step 201, at least one information of each food material type in multiple food material types is obtained.

The at least one information of the food material type may include: suitability information for indicating whether the material of the material type is suitable for storing in the storage compartment. If the suitability information of a certain food material type indicates that the food material of the food material type is suitable for being stored in the storage room, it can be determined that the refrigerator can play a fresh-keeping effect on the food material. If the suitability information for a food material type indicates that the food material of the food material type is not suitable for storage in the storage compartment, it can be determined that storing the food material in the refrigerator accelerates deterioration of the food material. For example, the suitability information may indicate the two cases by two different values, respectively, such as 0 and 1. When the value of the suitability information of the food material type is 1, the suitability information indicates that the food material of the food material type is suitable to be stored in the storage chamber; when the value of the suitability information of the food material type is 0, the suitability information indicates that the food material of the food material type is not suitable for storing in the storage chamber.

For example, the first influential information may indicate two cases, namely that the food material of the food material type can ripen the food material and that the food material of the food material type cannot ripen the food material, through two different numerical values. E.g. the two values may be 0 and 1, respectively. When the value of the first influential information of the food material type is 1, the first influential information indicates that the food material of the food material type can ripen the food material; when the value of the first influential information of the food material type is 0, the first influential information indicates that the food material of the food material type cannot ripen the food material.

Optionally, the at least one information of the food material type may further include: and second influential information which is used for indicating whether the food material of the type of the food material has the characteristic of being ripened or not, wherein a certain food material has the characteristic of being ripened, namely, the food material can be ripened by the food material, and a certain food material does not have the characteristic of being ripened, namely, the food material cannot be ripened by the food material. For example, the second influential information may indicate two cases, that the food material of the food material type can be ripened by the food material and the food material of the food material type cannot be ripened by the food material, respectively, through two different values. E.g. the two values may be 0 and 1, respectively. When the value of the second influential information of the food material type is 1, the second influential information indicates that the food material of the food material type can be ripened by the food material; when the value of the second influential information of the food material type is 0, the second influential information indicates that the food material of the food material type cannot be ripened by the food material.

In addition, in the embodiment of the application, whether the food material can be ripened and whether the food material can be ripened can be respectively indicated through the first influential information and the second influential information. Optionally, the first influential information and the second influential information of the food material type may also be represented by the same information, and this same information is referred to as influential information in this embodiment of the application. The influential information of a food material type can be used to indicate that the food material of the food material type can ripen, can be ripened by the food material, or can neither ripen nor be ripened by the food material. For example, the influence information may indicate the three cases by different three values, such as 1,0 and-1. When the value of the influential information of the food material type is 1, the influential information indicates that the food material of the food material type can ripen the food material; when the value of the influential information of the food material type is 0, the influential information indicates that the food material of the food material type can be ripened by the food material; when the value of the influential information for the food material type is-1, the influential information indicates that the food material of the food material type cannot be ripened by either the food material or the food material. Optionally, an optional value may be added to the influential information, and the optional value indicates that the food material has both the ripening characteristic and the ripened characteristic, that is, the food material can be ripened and ripened.

Optionally, the at least one information of the food material type may further include: a recommendation processing method of the food material type when stored. When the food materials of any food material type are stored, the corresponding recommendation processing method is adopted, so that the shelf life of the food materials can be prolonged, and the fresh-keeping effect of the refrigerator on the food materials can be improved.

Alternatively, a surface of the door of the refrigerator adjacent to the opening of the storage compartment may be provided with a shelf, and the plurality of storage regions may include storage regions partitioned by the shelf. Since there may be a difference between the temperature and the humidity of each location in the storage compartment, such as a lower temperature in an area near the top and a higher temperature in an area near the bottom of the refrigerating compartment, the storage compartment may be divided into a plurality of storage areas according to the temperature and the humidity of each location in the storage compartment. Alternatively, the division of the storage areas can also be carried out according to other parameters, for example, different storage areas can be divided according to the distance from the opening of the respective location in the storage compartment. For example, the identity of the storage area may be descriptive of where the storage area is located in the storage compartment, such as refrigerator compartment first floor, refrigerator door shelf; or the identification of the storage area may be the name assigned to the storage area, if a vegetable area, a meat area. The food materials are stored in different storage areas in the storage chamber, so that the preservation effect or the access convenience of the food materials can be influenced, and when the food materials of a certain food material type are stored in the storage area indicated by the identification of the recommended storage area corresponding to the food material type, the preservation effect or the access convenience of the food materials can be improved.

Optionally, the at least one information of the food material type may further include: store room parameter ranges. The storage compartment parameter range may comprise at least one of a suitable storage temperature range and a suitable storage humidity range of the food material.

Optionally, the at least one information of food material type may further comprise: store the chamber parameters. The food of any food type can have better fresh-keeping effect in the environment with the storage chamber parameters of the food type. Optionally, the storage parameter of the food type may be in a storage parameter range of the food type, and the storage parameter may be a parameter in the storage parameter range that is most suitable for storing food, and the food may obtain the best fresh-keeping effect in an environment of the storage parameter.

Optionally, the food material database may include at least one information of each of the plurality of food material types, the food material database may be stored in a memory of the refrigerator, and the controller may directly obtain the food material database from the memory to obtain the at least one information of each of the plurality of food material types. Or the food material database can also be stored in the internet, and the controller can access the internet to further acquire the food material database from the internet.

For example, the food material database can include the food material types shown in table 1 below and at least one information for each food material type. It should be noted that, the following table 1 only explains that the food material database includes three food material types, and the number of the food material types in the food material database may also be other values, such as seven, eight or even hundreds of thousands, which is not limited in the embodiment of the present application. In table 1 below, the storage chamber parameters are shown as examples including only temperature. Each piece of information of the food material types in table 1 below is only an example, and the information of the food material types in practical application may not be the same as the information in table 1 below, which is not limited in this embodiment of the application.

It should be noted that, in the embodiment of the present application, the at least one piece of information of each food material type in the multiple food material types in the food material database may all include: suitability information, first influential information, second influential information, recommended processing method, recommended storage area identification, storage room parameter, and storage room parameter range. Optionally, there may also be a case where some information of some food material types is empty in the plurality of food material types. As shown in table 1 below, "-" in table 1 below indicates that the identification of the recommended storage area in the at least one information of the material type banana is empty.

TABLE 1

Step 202, when the target food material is stored in the storage room, the suitability information of the type of the target food material is obtained. If the suitability information of the type of the target food material indicates that the target food material is not suitable for storing in the storage room, go to step 203; when the suitability information of the type of the target food material indicates that the target food material is suitable for storing in the storage room, step 204 is executed.

Wherein the target food material is a food material to be stored in the storage chamber, or a food material being stored into the storage chamber by a user. The type of the target food material is hereinafter referred to as the target food material type. When a user wants to store a target food material taken by the user in the storage room, the controller may first obtain the type of the target food material to obtain the type of the target food material. And further searching the suitability information of the target food material type in at least one information of the multiple food material types. The controller can determine whether the plurality of food material types comprise the target food material type, determine at least one piece of information of the target food material type when the plurality of food material types comprise the target food material type, and obtain suitability information from the at least one piece of information of the target food material type.

Alternatively, the controller may acquire the target food material type in various ways.

In a first optional implementation manner, the controller may determine the type of the target food material by means of image recognition. The controller can control the camera device to collect multi-frame images including hand areas at the opening of the refrigerator when determining that the door of the refrigerator is in an open state, and determine whether a user stores food materials into the refrigerator according to the multi-frame images including the hand areas. And when determining that the user is about to store food materials into the refrigerator, identifying the type of the food materials in the images collected by the camera device to obtain the type of the target food materials.

For example, the controller may acquire a frame of depth image after the camera device acquires the frame of depth image, and then perform hand detection on the frame of depth image to determine whether the frame of depth image is an image including a hand region. After determining the image including the hand region, the controller may further detect the image including the hand region, and determine whether the image is an image of a hand holding a food material. Then, the controller can determine the moving track of the hand with the food materials according to the multi-frame images of the hand with the food materials, and further determine whether the user stores the food materials into the refrigerator or not according to the moving track. If the moving track of the hand is a track moving from a position where the hand is far away from the storage chamber to a position where the hand is close to the storage chamber, the fact that the user wants to store food materials into the refrigerator can be determined.

The controller may directly input a frame of image including an image of a hand holding the food material into the food material type recognition model after determining that the frame includes the image, to obtain a recognition result of the frame of image output by the food material type recognition model. The recognition model can be used to output a food material type and a confidence of the food material type based on an input image. The controller may determine the food material type corresponding to the maximum confidence in the recognition results of the images of the multiple frames of the hand-held food materials as the target food material type.

In a second alternative implementation manner, the controller may determine the target food material type by means of user input. The controller may control the information output assembly in the refrigerator to output a prompt message for determining whether to store the food material when determining that the refrigerator door is in an open state, and determine whether to store the food material according to the response message input by the user through the information input assembly in the refrigerator. When the user is determined to store the food materials, the information output component can be controlled to output prompt information prompting the input of the target food material type, and the target food material type is determined according to the response information input by the user through the information input component. Optionally, the controller may also output a prompt message for inputting the type of the target food material if the food material is to be stored together when the controller information output component outputs a prompt message for determining whether the food material is to be stored. Optionally, the information output component may include at least one of a speaker, a display screen, an indicator light, and a terminal communicatively connected to the controller, and the information input component may include at least one of a microphone, a display screen, and a terminal communicatively connected to the controller.

Illustratively, the information output component includes a speaker and the information input component includes a microphone. When the controller determines that the refrigerator door is in an open state, the controller can control the loudspeaker to play a first prompt voice for determining whether the food material needs to be stored, collects a first response voice collected by the microphone within a target time length after the prompt information is played by the loudspeaker, and analyzes the first response voice to determine whether the food material needs to be stored by a user. The controller can also control the loudspeaker to play a second prompt voice prompting input of the type of the target food material, acquire a second response voice collected by the microphone within a target time length after the loudspeaker plays the prompt information, and analyze the second response voice to determine the type of the target food material. Optionally, the first prompt voice and the second prompt voice can be played simultaneously, and then the user can input a first response voice indicating whether to store the food material and a second response voice indicating the type of the target food material together.

If the controller determines that the refrigerator door is in the open state, the controller can control the speaker to play' do you store food, ask what food to store if you store food? When hearing the voice, the user can say 'store in apple', and then the microphone can collect the voice. The controller can analyze the voice collected by the microphone to determine that the user stores the food material, and the stored food material is an apple, namely the type of the target food material is an apple. Optionally, the controller may also control the display screen or a terminal in communication connection with the controller to output prompt information; the user may also input the type of the food material in a manner of inputting on a touch display screen of the refrigerator or in a manner of inputting on a terminal in communication connection with the controller, which is not limited in the embodiment of the present application.

Optionally, in this second optional implementation manner, the controller may also determine whether the user stores the food material in an image recognition manner, and reference may be made to the description of the first optional implementation manner for determining whether the user stores the food material in the image recognition manner, which is not described again in this embodiment of the application.

It should be noted that, in the embodiment of the present application, the controller may optionally select one of the two optional implementation manners to obtain the type of the target food material; or when the type of the target food material is not determined through the first optional implementation manner, the type of the target food material is determined through the second optional implementation manner.

Since the suitability information of the food materials in different processing states may be different, the controller may further determine the processing state information of the food materials to be stored in the storage chamber in an image recognition manner or a user input manner, so as to further accurately determine whether the target food materials are suitable for storage in the storage chamber. If the target food material is pumpkin, the pumpkin is not suitable to be stored in the storage chamber when the pumpkin is in an uncut state, and the pumpkin is suitable to be stored in the storage chamber when the pumpkin is in a cut state. Optionally, at this time, the food material type in the food material database may carry the processing state of the food material.

And 203, triggering the information output component to output prompt information that the target food material is not suitable for being stored in the storage room.

When the suitability information of the type of the target food material searched by the controller indicates that the target food material is not suitable for being stored in the storage room, the controller can control the information output assembly to output prompt information that the target food material is not suitable for being stored in the storage room. After learning the prompt message, the user can know that the target food material is stored in the storage room, so that the deterioration of the food material is accelerated, and the food material is not stored in the storage room.

Exemplarily, the type of the target food material is banana, and the controller can play a prompt message that the banana is not suitable for being stored in the storage room through the controller loudspeaker or control the display screen to display the prompt message that the banana is not suitable for being stored in the storage room. Optionally, the controller may also output the prompt via an indicator light. For example, the indicator light can be controlled to emit light with a specific color, and for example, the controller can control the sub indicator light at the top of the storage room to emit red light; or the indicator light is controlled to sequentially emit light of a plurality of colors according to a specific light-emitting sequence, or the indicator light can be controlled to output prompt information in other light-emitting modes.

Optionally, when the suitability information of the target food material type indicates that the target food material is not suitable for storage in the storage room, the controller can also obtain the storage room parameter or the storage room parameter range of the target food material type and output prompt information of the storage room parameter or the storage room parameter range of the target food material type. The user can determine the environmental parameters suitable for storing the target food material through the prompt message, and the environmental parameters are the storage chamber parameters or the storage chamber parameter range of the type of the target food material, so that the user can store the target food material in the environment with the storage chamber parameters or the storage chamber parameter range.

For example, the controller can search the storage chamber parameter range of the target food material type in the food material database, and then output the prompt message of the storage chamber parameter range of the target food material type. The storage chamber parameter range of the target food material type is also the storage chamber parameter range corresponding to the target food material. If the target food material type is banana, the storage chamber parameter of the target food material type is normal temperature, and the normal temperature refers to a temperature range of 20-25 ℃, and the controller can control the loudspeaker to play prompt information that the banana is suitable to be stored in a normal temperature environment. Further, for example, the controller can search the storage parameter of the target food material type in the food material database, and then output the prompt message of the storage parameter of the target food material type. If the target food material type is banana, the storage chamber parameter of the target food material type is 20 ℃, and the controller can play prompt information of 'banana is suitable to be stored in an environment with 20 ℃ through the controller loudspeaker'.

It should be noted that, in the embodiment of the present application, the storage chamber parameter of the food material type only includes the temperature, and the storage chamber parameter range only includes the temperature range as an example for explanation. Optionally, the storage chamber parameter of the food material type may also include humidity, the storage chamber parameter range may also include a humidity range, and for the case that the storage chamber parameter includes humidity, reference may be made to the related description of temperature, which is not described in detail in the embodiments of the present application.

And step 204, obtaining the influence information of the target food material type. When the influential information indicates that the target food material can ripen the food material, executing step 205; when the influential information indicates that the target food material can be ripened by the food material, executing step 207; when the influential information indicates that the target food material cannot ripen and cannot be ripened by the food material, step 209 is executed.

When the suitability information for the type of the target food material indicates that the target food material is suitable for storage in the storage compartment, the controller can determine whether there are other factors affecting the freshness effect of the food material to be stored in the storage compartment.

Because some edible materials are stored together and possibly influence each other, if a certain edible material can be ripened, or a certain edible material can be ripened by the edible material, the stored edible materials are too ripe early, the freshness keeping effect of the edible materials is further influenced, and whether the edible materials are mutually influenced is a factor influencing the freshness keeping effect of the edible materials. Since the influential information of the type of food material can indicate whether the food material can ripen and be ripened by the food material, the controller can acquire the influential information of the type of the target food material, and then determine whether there is a food material in the storage chamber that can interact with the target food material according to the influential information. For example, the controller can perform a lookup in the food material database based on the target food material type to obtain the influential information in the at least one information of the target food material type.

When the influential information of the type of the target food material indicates that the target food material cannot ripen and cannot be ripened by the food material, the controller may determine that there is no food material that can interact with the target food material, so it may be directly determined that there is no food material in the storage chamber that can interact with the target food material.

Step 205, determining whether the first food material is stored in the storage room. When the first food material is stored in the storage chamber, step 206 is executed. If the first food material is not stored in the storage chamber, step 209 is executed.

The multiple food material types in the food material database comprise the type of the first food material, and the influence information of the type of the first food material indicates that the first food material can be ripened by the food material.

It should be noted that when the influential information of the type of the target food material indicates that the target food material can ripen, the controller can further determine whether a food material that is influential with the target food material is already stored in the storage chamber. Such as determining whether a food material capable of being ripened by the target food material is stored in the storage chamber. For example, the controller can determine the types of at least one type of food materials stored in the storage room, and then search the influence information of each type in the food material database to determine whether each type of food materials can be ripened by the food materials. When it is determined that a certain type of food material among the food materials stored in the storage chamber can be ripened by the food material, the controller may determine that a first food material, that is, the food material stored in the storage chamber and capable of being ripened by the food material, is stored in the storage chamber. Because the target food material can be used for ripening, the first food material can be used for ripening, so that the controller can determine that the first food material can be used for ripening, and the first food material can be influenced with the target food material. When it is determined that there is no food material capable of being ripened by the food material in the food materials stored in the storage chamber, the controller may determine that the first food material is not stored in the storage chamber, and there is no food material capable of interacting with the target food material in the storage chamber.

Alternatively, a storage of the refrigerator may have stored therein a food material information base including types of at least one type of food material stored in the storage chamber. For example, the controller may acquire the type of the food material each time the food material is stored in the storage chamber, store the type of the food material in the food material information library, acquire the type of the food material when the food material is taken out of the storage chamber, and delete the type of the food material from the food material information library, so as to ensure that the type of the food material in the food material information library is the type of the food material stored in the storage chamber. The manner in which the controller acquires the type of the food material may refer to the related introduction of the controller acquiring the type of the target food material in step 202, which is not described in this embodiment of the present application again. The controller can directly acquire the type of at least one type of food material in the food material information base, and further determine the type of the at least one type of food material in the food material information base as the type of the at least one type of food material stored in the storage chamber.

Optionally, the food material information base may further include at least one information of types of various food materials stored in the storage chamber. The at least one type of information of the food material type in the food material information base is similar to the at least one type of information of the food material type in the food material database, and for the food material information base, reference may be made to the introduction of the food material database in step 201, which is not described in detail in the embodiments of the present application.

And step 206, triggering an information output component to output prompt information that the target food material can ripen the first food material.

After the controller determines that the first food material is stored in the storage chamber, the controller can determine that the target food material can ripen the first food material, and then the controller can control the information output component to output prompt information that the target food material can ripen the first food material. After learning the prompt message, the user can know that the target food material is stored in the first food material in the storeroom to hasten ripening, and then the user can further determine whether to store the target food material in the storeroom. If the user can not store the target food material into the storage room; or the user can store the target food material into the storage chamber and take the first food material out of the storage chamber, so that the first food material is prevented from being deteriorated in an accelerated manner due to the fact that the target food material is stored into the storage chamber.

Illustratively, the target food material is an apple, the first food material is a pear, and the controller can control the speaker to play a prompt message of 'the apple can ripen the pear in the storage room', or control the display screen to display a prompt message of 'the apple can ripen the pear in the storage room'. The controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

Optionally, after determining that the first food material is stored in the storage chamber, the controller may further determine a storage location of the first food material and output a prompt message of the storage location. For example, the controller can simultaneously prompt the target food material to ripen the first food material and prompt the storage position of the first food material through a prompt message. Exemplarily, the type of the target food material is apple, the first type is pear, the storage position of the pear is the second layer of the refrigerating chamber, and the controller can control the loudspeaker to play prompt information of 'the apple can ripen the pear stored on the second layer of the refrigerating chamber', or control the display screen to display prompt information of 'the apple can ripen the pear stored on the second layer of the refrigerating chamber'. It should be noted that the controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

In the embodiment of the application, when the controller determines that the influence information of the type of the target food material indicates that the target food material can ripen the food material, it is directly determined whether the first food material is stored in the storage chamber. Optionally, when determining that the influential information of the type of the target food material indicates that the target food material has the ripening characteristic, the controller may directly output a prompt that the target food material has the ripening characteristic, or may also directly output a prompt that the target food material can ripen the food material. At this time, the controller may not perform step 205 and step 206, or the controller may still perform step 205 and step 206, and the embodiment of the present invention is not limited. Optionally, when it is determined in step 205 that the first food material is not stored in the storage chamber, a prompt that the target food material has the ripening characteristic or a prompt that the target food material can ripen the food material may be directly output, and then step 209 is executed; or only the prompt message that the target food material has the ripening characteristic or the prompt message that the target food material can ripen the food material can be output without executing the step 209; or, no prompt information may be output and step 209 is not performed, and the embodiment of the present application is not limited.

For example, the controller may control the information output component to output a prompt that the target food material is capable of ripening the food material. After learning the prompt message, the user can know that the target food material can be ripened, and if the target food material is stored in the storage chamber, the user can possibly ripen the food material stored in the storage chamber, and then the user can further determine whether to store the target food material in the storage chamber. For example, the target food material is an apple, and the controller may control the speaker of the controller to play a prompt message that "the apple can ripen the food material", or control the display screen to display a prompt message that "the apple can ripen the food material". Optionally, the controller may also output the prompt through an indicator light. For example, the indicator light can be controlled to emit light with a specific color, and for example, the controller can control the sub indicator light at the top of the storage room to emit yellow light; or the indicator light is controlled to sequentially emit light of a plurality of colors according to a specific light-emitting sequence, or the indicator light can be controlled to output prompt information in other light-emitting modes.

And step 207, determining whether the second food material is stored in the storage room. When the second food material is stored in the storage chamber, step 208 is executed. If the second food material is not stored in the storage chamber, step 209 is executed.

The plurality of food material types comprise a type of a second food material, and the influential information of the type of the second food material indicates that the second food material is capable of ripening.

It should be noted that when the influential information of the target food material type indicates that the target food material can be ripened by the food material, the controller can further determine whether the food material interacting with the target food material is stored in the storage chamber. Such as determining whether a food material capable of ripening the target food material has been stored in the storage chamber. For example, the controller may determine the type of at least one food material stored in the storage room, and then search the food material database for the influential information of each type to determine whether the food material of each type can ripen the food material. When it is determined that a certain type of food material among the food materials stored in the storage chamber can ripen the food material, the controller may determine that a second food material, that is, a food material stored in the storage chamber that can ripen the food material, is stored in the storage chamber. Because the target food material can be ripened by the food material, the second food material can ripen the food material, the controller can determine that the second food material can ripen the target food material, which can interact with the target food material. When it is determined that there is no food material capable of ripening among the food materials stored in the storage chamber, the controller may determine that the second food material is not stored in the storage chamber, and there is no food material capable of interacting with the target food material in the storage chamber.

And step 208, triggering the information output component to output prompt information that the target food material can be ripened by the second food material.

After the controller determines that the second food material is stored in the storage chamber, the controller can determine that the target food material can be ripened by the second food material, and then the controller can control the information output component to output prompt information that the target food material can be ripened by the second food material. After learning the prompt message, the user can know that the target food material is stored in the storage room and can be ripened by the second food material in the storage room, and then the user can further determine whether to store the target food material in the storage room. If the user can not store the target food material into the storage room; or the user can store the target food material into the storage chamber and take the second food material out of the storage chamber, so that the situation that the target food material is stored into the storage chamber and is accelerated to deteriorate due to ripening of the second food material is avoided.

Illustratively, the target food material is pears, the second food material is apples, and the controller may control the speaker to play a prompt message of "pears can be ripened by apples in the storage room" or control the display screen to display a prompt message of "pears can be ripened by apples in the storage room". It should be noted that the controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

Optionally, after determining that the second food material is stored in the storage chamber, the controller may further determine a storage location of the second food material and output a prompt message of the storage location. For example, the controller can simultaneously prompt the target food material to be ripened by the second food material and the storage position of the second food material through a prompt message. Illustratively, the target food material is pears, the second food material is apples, the storage positions of the apples are the second layer of the refrigerating chamber, and the controller can control the loudspeaker to play prompt messages of 'pears can be ripened by the apples stored in the second layer of the refrigerating chamber', or control the display screen to display prompt messages of 'pears can be ripened by the apples stored in the second layer of the refrigerating chamber'. It should be noted that the controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

In the embodiment of the application, when the controller determines that the influence information of the type of the target food material indicates that the target food material can be ripened by the food material, it is directly determined whether the second food material is stored in the storage chamber. Optionally, when determining that the influential information of the type of the target food material indicates that the target food material has the accelerated ripening characteristic, the controller may directly output a prompt that the target food material has the accelerated ripening characteristic, or may also directly output a prompt that the target food material can be ripened by the food material. At this time, the controller may not perform step 207 and step 208, or the controller may still perform step 207 and step 208, which is not limited in the embodiment of the present application. Optionally, when it is determined in step 207 that the first food material is not stored in the storage chamber, a prompt message that the target food material has the characteristic of being ripened or a prompt message that the target food material can be ripened by the food material may be directly output, and then step 209 is performed; or only the prompt message that the target food material has the accelerated ripening characteristic or the prompt message that the target food material can be accelerated by the food material is directly output without executing the step 209; or, no prompt information may be output and step 209 is not performed, and the embodiment of the present application is not limited.

For example, the controller may control the information output component to output a prompt that the target food material can be ripened by the food material. After learning the prompt message, the user can know that the target food material can be ripened by the food material, if the target food material is stored in the storage chamber, the target food material can be ripened by the food material stored in the storage chamber, and then the user can further determine whether the target food material is stored in the storage chamber. For example, the target food material is pear, and the controller can control the loudspeaker to play a prompt message of 'pear can be ripened by food material', or control the display screen to display a prompt message of 'pear can be ripened by food material'. Optionally, the controller may also output the prompt via an indicator light. If the indicator light can be controlled to emit light with a specific color, the controller can control the sub indicator light at the top of the storage room to emit blue light; or the indicator light is controlled to sequentially emit light with a plurality of colors according to a specific light emitting sequence, or the indicator light can be controlled to output prompt information in other light emitting modes.

Optionally, in steps 206 and 208 in the embodiment of the present application, the prompting information output by the controller controlling the information output component may not include the type of the first food material and the type of the second food material, and the prompting information may be only used for prompting that there is a food material in the storage room that affects the target food material. Optionally, the prompt message may also prompt the storage location of the food material interacting with the target food material. For example, the controller may control the indicator light to output the prompt message. For example, the controller may control the target sub-indicator to change the lighting color, or to emit light of a specific color, or to flash. The target sub-indicator lamp is located in the storage area where food materials mutually influenced with the target food material are located.

And 209, acquiring a recommendation processing method of the target food material during storage. Step 210 is performed.

When the controller determines that no food material which can mutually influence the target food material exists in the storage chamber, the controller can determine that the target food material is directly stored in the storage chamber, the preservation effect of the target food material cannot be influenced, and the preservation effect of the food material stored in the storage chamber cannot be influenced. The controller may then determine whether there are other factors that affect the freshness effect of the food material. Because the food materials are processed by different processing methods and then stored with different fresh-keeping effects, the processing method of the food materials in the storage chamber is a factor influencing the fresh-keeping effect of the food materials. The controller can acquire a recommendation processing method of the target food material during storage, and the freshness keeping effect of the target food material can be improved by processing the target food material by adopting the recommendation processing method during storage of the target food material. For example, the controller can search the food material database for the recommended processing method in at least one information of the target food material type.

Illustratively, the food material processing method may include a wrapping method, a processing method, or a placing method. For example, some food materials (such as dried fish and fruits or cut pumpkin) are wrapped by a preservative film or a vacuum bag to improve the preservation effect, and some food materials (such as green leaf vegetables) are wrapped to accelerate the rotting of the food materials or destroy the characteristics of the food materials. Some food materials need to be cut or cooked to a certain extent, for example, the radish needs to be cut off the leaves at the head. Some edible materials are different in the fresh-keeping effect under the mode of putting of difference, like egg extension and external temperature influence, the albumen can become thin yolk and can up float, but the big head of egg has an air chamber, and the big head is up when placing the egg, even the albumen becomes thin yolk and floats, can not make the yolk paste on the eggshell yet for the fresh-keeping effect of egg is better. Therefore, the recommended processing method of the dried fish and fruit food materials or the cut pumpkin can be as follows: wrapping with preservative film or vacuum bag; the recommended treatment method of the radish can be as follows: cutting off the head leaves; the recommended processing method of the eggs comprises the following steps: the big head is upward and the small head is placed under.

Step 210, triggering an information output component to output prompt information of a recommended processing method of the target food material during storage. Step 211 is performed.

When the controller determines the recommended processing method of the target food material when stored, the information output component may be controlled to output prompt information of the recommended processing method of the target food material when stored. After obtaining the prompt information, the user can know that the target food material is processed by the recommendation processing method during storage, so that the preservation effect of the food material can be improved, and the user can process the target food material by the recommendation processing method.

For example, the target food material is an egg, and the controller may control the speaker to play a prompt message of "the recommended big head of the egg is upward and the small head is placed below" or control the display screen to display a prompt message of "the recommended big head of the egg is upward and the small head is placed below". The controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

Step 211, obtaining an identifier of a recommended storage area of the target food material type in the plurality of storage areas. Step 212 is performed.

It should be noted that the plurality of storage areas may be a plurality of storage areas obtained by dividing the storage room, and each storage area may have a corresponding identifier. The dividing manner of the storage areas and the identification of the storage areas may refer to the related description in step 201, and are not described in detail in this embodiment of the present application. For example, the controller can look up an identification of the recommended reserve area of the target food material type in the food material database, which can indicate the recommended reserve area of the target food material.

And step 212, triggering the information output component to output prompt information for storing the target food materials into the recommended storage area according to the identification of the recommended storage area. Step 213 is performed.

After the identification of the recommended storage area of the type of the target food material is obtained, the controller can output prompt information for storing the target food material into the recommended storage area according to the identification of the recommended storage area. After knowing the prompt information, the user can store the target food materials in the recommended storage area, so that the freshness retaining effect or the access convenience of the target food materials are further improved.

For example, the target food material is eggs, and the identifier of the recommended storage area of the eggs is "refrigerator door shelf", the controller may play a prompt message of "recommended placing of eggs into refrigerator door shelf" through the controller speaker. Optionally, the controller may also output the prompt via an indicator light. For example, the sub-indicator lights in the recommended storage area can be controlled to change the lighting color or emit light with a specific color to prompt the user to store the target food material in the recommended storage area.

It should be noted that, in the embodiment of the present application, step 209 to step 212 are sequentially executed as an example, optionally, step 211 and step 212 may be executed first, and then step 209 and step 210 are executed, or step 209 and step 211 may be executed in parallel, which is not limited in the embodiment of the present application.

The presentation information in step 203, step 206, step 208, step 209, step 210, and step 212 may be information of storage guidance related to the target food material.

Step 213, obtaining the storage chamber parameters of each type of food material when the target food material is stored in the storage chamber and the plurality of types of food materials comprise the type of each type of food material in at least one type of food material stored in the storage chamber. Step 214 is performed.

After the target food material is stored in the storage chamber, the controller may obtain the type of at least one type of food material in the food material information database, where the type of at least one type of food material in the food material information database is the type of at least one type of food material stored in the storage chamber, and the type of at least one type of food material may include the type of the target food material. The food material information base may refer to the related description in step 205, and the embodiment of the present application is not described again. The controller can search the storage chamber parameters of the types of the food materials in the food material database according to the acquired types of the food materials stored in the storage chamber, wherein the storage chamber parameters of the types of the food materials are storage chamber parameters corresponding to the food materials.

Illustratively, the food material information base includes two food material types egg and apple. When the controller obtains the two food material types in the food material information base, the storage chamber parameters of eggs and the storage chamber parameters of apples can be respectively searched in the food material database. If the controller searches in the table 1, the parameters of the storeroom of the eggs are determined to be 5 ℃ and the parameters of the storeroom of the apples are determined to be 7 ℃.

It should be noted that, in the above embodiments of the present application, the controller directly obtains the storage chamber parameters of the food material types from the food material database as an example. Alternatively, only the storage compartment parameter range of the food material type may be included in the food material database, and not the storage compartment parameter of the food material type. At the moment, the controller can acquire the storage chamber parameter range of the food material type, and further determine the storage chamber parameter of the food material type according to the storage chamber parameter range. For example, the controller may determine a median value in the range of the storage chamber parameters of the food material type as the storage chamber parameters of the food material type, or the controller may determine a maximum value or a minimum value in the range of the storage chamber parameters as the storage chamber parameters of the food material type, or the controller may determine the storage chamber parameters according to other calculation methods, which is not limited in the embodiment of the present application.

Step 214, determining recommended parameters of the storage room according to the storage room parameters of the types of the at least one type of food materials. Step 215 is performed.

After determining the storage chamber parameters of the type of at least one type of food material stored in the storage chamber, the controller may determine parameters of the storage chamber that enable the preservation effect of the at least one type of food material currently stored in the storage chamber to be better, that is, recommended parameters of the storage chamber, according to the storage chamber parameters of the type of the at least one type of food material.

For example, the controller may determine an average value of the parameters of the storage compartment for the type of the at least one type of food material as the recommended parameter of the storage compartment. For example, the food material information base comprises two food material types of eggs and apples. The storeroom parameter of egg is 5 degrees centigrade, and the storeroom parameter of apple is 7 degrees centigrade, then the controller can confirm that the recommended parameter of storeroom is 6 degrees centigrade.

Step 215, triggering the information output component to output prompt information for adjusting the parameters of the storage room to recommended parameters. Step 216 is performed.

After the controller determines the recommended parameters of the storage room, the controller information output component can output prompt information for adjusting the parameters of the storage room to the recommended parameters, so that a user can manually adjust the parameters of the storage room to the recommended parameters according to the prompt information.

For example, the recommended parameter of the storage room determined by the controller is 6 degrees celsius, and the controller may play a prompt message of "recommend to adjust the temperature of the storage room to 6 degrees celsius" through the controller speaker. It should be noted that the controller may also output the prompt information in other manners, which may specifically refer to the related description of the controller controlling the information output component to output the prompt information in step 202, and the embodiments of the present application are not described again. For example, the refrigerator may include a parameter adjustment assembly, such as a display screen, an adjustment button, or an adjustment knob. The user can adjust the parameters of the storage chamber of the refrigerator by operating the parameter adjusting assembly.

Alternatively, the controller may directly adjust the parameters of the storage room to the recommended parameters. In this case, the prompt information may not be output, or the prompt information may be output after the adjustment to adjust the parameter of the storage room to the recommended parameter.

It should be noted that, in the embodiment of the present application, the storage chamber parameters of the food material types only include the temperature, and further, the recommended parameters of the storage chamber also only include the temperature. Optionally, the storage chamber parameter of the food material type may also include humidity, so the recommended parameter of the storage chamber may also include humidity, and for the case that the storage chamber parameter includes humidity, reference may be made to the related introduction of temperature, which is not described in detail in the embodiment of the present application.

Optionally, when the parameters of each storage area in the storage room can be respectively adjusted, the controller may also determine the recommended parameters of each storage area according to the storage room parameters of the types of food materials stored in each storage area, and then output prompt information for adjusting the parameters of the storage area to the corresponding recommended parameters.

Step 216, obtaining the storage chamber parameter range corresponding to each type of food material in the at least one type of food material. Step 217 is performed.

The controller may determine the type of at least one type of food material stored in the storage chamber, and then search the storage chamber parameter range of the type of each type of food material in the at least one type of food material in the food material database, that is, search the storage chamber parameter range corresponding to each type of food material.

And step 217, outputting prompt information that the third food material is not suitable for being stored in the storage room under the recommended parameter when the recommended parameter is out of the storage room parameter range corresponding to the third food material.

The controller may compare the storage chamber parameter range corresponding to each of the at least one type of food material with the recommended parameter of the storage chamber to determine whether the storage chamber parameter range corresponding to a food material in the at least one type of food material does not include the recommended parameter, that is, the recommended parameter is located outside the storage chamber parameter range of the food material. When determining that the storage chamber parameter range of a certain food material does not include the recommended parameter, the controller may determine that the food material is a third food material that is not suitable for storage in the storage chamber under the recommended parameter, and then the controller may control the information output component to output prompt information that the third food material is not suitable for storage in the storage chamber under the recommended parameter.

For example, the recommended parameter of the storage chamber is 7 degrees celsius, the food material a is stored in the storage chamber, and the storage chamber parameter range of the food material a is 3 to 5 degrees celsius, the controller may determine that the food material a is a third food material, and the food material a is not suitable for being stored in an environment at 7 degrees celsius. And the controller can control the loudspeaker to play prompt information that the food material A in the storage room is not suitable for being stored in the storage room at 7 ℃. After the user knows the prompt message, the user can adjust the parameters of the storeroom again, or the user can take the food material A out of the storeroom. The controller may also output the prompt information in other manners, and the embodiment of the present application is not limited.

It should be noted that, in the embodiment of the present application, step 213 to step 217 are performed as an example after step 212. Alternatively, the steps 213 to 217 may be performed once the controller determines that the food material is stored in the storage chamber, and the embodiment of the present invention is not limited thereto. If the controller determines that only the food material is stored in the storage chamber without performing the above steps 201 to 212, the controller may perform the above steps 213 to 217.

The following explains the information prompting method provided by the embodiment of the present application by three examples:

for example, when the user opens the refrigerator door and stores the target food material banana into the storage chamber, the controller may acquire an image collected by the camera device, and identify the image to determine that the type of the target food material is banana. The controller can inquire the food material database to determine that the suitability information of the bananas is 0, the suitability information indicates that the target banana food material is not suitable to be stored in the storage chamber, and then the controller can control the loudspeaker to broadcast the prompt message that the bananas are not suitable to be placed in the refrigerator. Optionally, the controller may further query the food material database to determine the recommendation processing method of bananas, and then voice-broadcast the recommendation processing method. It should be noted that, in the embodiment of the present application, the recommended storage area of the food material type in the food material database is only an example of a storage area in the storage room. At this time, when the suitability information of the food material type indicates that the food material of the food material type is not suitable for storing in the storage chamber, the identification of the recommended storage area in the at least one information of the food material type may be empty. The identification of the recommended storage area is empty in at least one of the information of bananas as shown in table 1. Alternatively, when the suitability information of the food material type indicates that the food material of the food material type is unsuitable to be stored in the storage compartment, the recommended storage area of the food material type may also be another storage area other than the storage compartment. If the mark of the recommended storage area of bananas can be a ventilating place which is cool and cool at normal temperature, the controller can also obtain the mark of the recommended storage area of bananas at the moment, and the loudspeaker is controlled to broadcast the prompt message that the bananas are placed into the recommended storage area in a voice mode.

For another example, when the user opens the refrigerator door and deposits eggs of the target food material into the storage chamber, the controller may acquire an image captured by the camera device, and identify the image to determine that the type of the target food material is eggs. The controller may query the food material database to determine that the suitability information of the eggs, which indicates that the eggs are suitable for storage in the storage compartment, is 1. The controller can also inquire the influence information of the eggs to be-1, namely the eggs can not be used for accelerating the cooking of the food materials and can not be used for accelerating the cooking of the food materials. The controller may also query for recommended treatment methods and recommended storage areas for eggs. Furthermore, the controller can control the loudspeaker to broadcast the voice of 'eggs are recommended with big heads upward and small heads downward and placed into a refrigerator door shelf of a refrigerator refrigerating chamber'.

Optionally, as shown in table 1, the at least one information of the food material type may further comprise a volume of the food material type. The recommended storage area may further include a plurality of sub-storage areas, and the controller may determine the recommended sub-storage area among the plurality of sub-storage areas in combination with the volume and a remaining containable volume in the recommended storage area, and then output a prompt to store the food material of the food material type in the recommended sub-storage area. The controller can determine the residual volume of each layer of the refrigerator door of the refrigerator refrigerating chamber, and in combination with the volume of the eggs to be stored, the recommended sub-storage area is determined to be the X-th layer of the refrigerator door shelf, and then voice broadcast is performed, wherein the X-th layer of the refrigerator door shelf of the refrigerator refrigerating chamber is placed with the big head upwards and the small head downwards. The controller can also query the food material database to obtain storage chamber parameters (such as temperature) of eggs, calculate the mean value of the storage chamber parameters of all food materials in the current storage chamber to obtain recommended parameters (such as recommended temperature) of the storage chamber, and further control the loudspeaker to play voice to recommend and adjust the temperature of the storage chamber to the recommended temperature. And the controller may determine whether a third food material unsuitable for storage in the storage chamber at the recommended temperature exists among the food materials stored in the storage chamber, and output a prompt message when determining that the third food material unsuitable for storage in the storage chamber at the recommended temperature exists.

Further, for example, when the user opens the refrigerator door and stores the apple serving as the target food material into the storage chamber, the controller may acquire an image captured by the camera device, and identify the image to determine that the type of the target food material is the apple. The controller may query the food material database to determine that the suitability information for the apple is 1, the suitability information indicating that the apple is suitable for storage in the storage compartment. The controller can also inquire that the influence information of the apples is 1, namely the apples can ripen food materials. Further, the controller may query the food material database to determine a type of which the influential information is 0 among the types of food materials stored in the storage chamber, and if the type is B, the controller may control the speaker to play "the apple can ripen the B food material in the refrigerator" in a voice. Further, the controller can also inquire to obtain a recommended processing method and a recommended storage area of the apples, and further can control the loudspeaker to broadcast the 'recommended fresh-keeping bags for the apples, and the apples are placed in the fruit and vegetable area in the refrigerating chamber of the refrigerator' through voice broadcasting.

To sum up, in the refrigerator provided by the embodiment of the application, the controller can trigger the information output assembly to output the information of the storage guidance related to the target food material when the target food material is stored in the storage chamber. Therefore, the user can store the target food material according to the storage guidance information in a proper mode, and the food material fresh-keeping effect of the refrigerator is guaranteed.

The controller can trigger the information output component to prompt when the target food material is determined to be unsuitable to be stored in the storage room. Therefore, when the target food material is stored in the refrigerator, a user can directly know whether the target food material is suitable for being stored in the refrigerator, the situation that the food material unsuitable for being stored in the refrigerator is stored in the refrigerator by the user, so that the food material deterioration is accelerated is avoided, and the fresh-keeping effect of the refrigerator on the food material is ensured.

The controller can also determine whether the target food material and the food material stored in the storage chamber are mutually influenced, can trigger the information output component to output a recommendation processing method when the target storage food material is stored and prompt information of a recommended storage area, and can also trigger the information output component to output the prompt information of recommended parameters of the storage chamber according to the stored food material. Furthermore, the user can only process the food materials which are suitable to be placed in the storeroom according to the prompt information output by the controller by the recommended processing method and place the food materials into the recommended storage area, and the parameters of the storeroom can be adjusted to the recommended parameters, so that the fresh-keeping effect of the food materials in the storeroom is further improved.
