In the non-independent temperature control mode, only the main temperature sensor participates in the temperature control, and the remaining first temperature sensors 101 do not participate in the control, and therefore, the remaining first temperature sensors 101 other than the main temperature sensor may be housed in the housing portion 13 so as not to interfere with the cooking accessory 40. In the non-independent temperature control mode, the temperature of the main temperature sensor and the temperature of the furnace core are in one-to-one mapping relation, and after the target temperature of the furnace core is determined, the temperature of the furnace core is adjusted according to the temperature measured by the main temperature sensor as a reference so as to achieve the aim of accurately controlling the temperature. For example, if the value of the main temperature sensor is 220 ℃, the corresponding core temperature is 218 ℃. If the target temperature of the core is 218 ℃, when the value of the main temperature sensor is less than 220 ℃, the first heating element 20 and the second heating element 30 are controlled to increase the operating power, so that the temperature of the core is increased until the value of the main temperature sensor is 220 ℃, and the temperature of the core can be regulated to 218 ℃.
In some embodiments of the invention, the method further comprises the steps of:
the control of the switching of the main temperature sensor to the first position further comprises:
acquiring an independent temperature control mode instruction, wherein the independent temperature control mode is to respectively control the first heating element 20 and the second heating element 30, so that the first heating element 20 and the second heating element 30 are respectively heated to different temperatures;
Determining the cooking accessory 40 close to the first heating element 20 positioned at the bottom wall 121 of the baking cavity 11 as a second target cooking accessory 40 according to the independent temperature control mode command and the position of each cooking accessory 40, wherein the second target cooking accessory 40 is the cooking accessory 40 closest to the first heating element 20;
Determining a first temperature sensor 101 adjacent to the second target cooking accessory 40 and located between the second target cooking accessory 40 and the first heating member 20 as a secondary temperature sensor according to the second target cooking accessory 40, determining the secondary temperature sensor as the first temperature sensor 101 located between the second target cooking accessory 40 and the first heating member 20 and closest to the second target cooking accessory 40, the secondary temperature sensor being capable of rapidly and accurately reflecting the temperature of the area of the second target cooking accessory 40 facing the side of the first heating member 20;
The secondary temperature sensor is controlled to be switched to the first position so that the secondary temperature sensor extends into the baking chamber 11, so that the temperature measured by the secondary temperature sensor reflects the temperature of the heated region of the first heating member 20.
It should be noted that, in the independent temperature control mode, the primary temperature sensor reflects the temperature of the area heated by the second heating element 30, and the secondary sensor reflects the temperature of the area heated by the first heating element 20, so that the second heating element 30 may be controlled based on the temperature value measured by the primary temperature sensor, and the first heating element 20 may be controlled based on the temperature value measured by the secondary temperature sensor, so as to achieve separate control of the first heating element 20 and the second heating element 30.
In some embodiments of the invention, the method further comprises the steps of:
judging whether each first temperature sensor 101 is a primary temperature sensor or a secondary temperature sensor, and if the first temperature sensor 101 is not marked as a primary sensor or a secondary sensor, indicating that the first temperature sensor 101 is not involved in temperature control of the oven;
If not, the first temperature sensor 101 is controlled to switch to the second position, so that the first temperature sensor 101 which is not involved in the temperature control of the oven is accommodated in the accommodating portion.
In some embodiments of the invention, the method further comprises the steps of:
acquiring a cooking end instruction or a pause instruction;
according to the cooking end command or the pause command, the at least one first temperature sensor 101 is controlled to switch to the second position to prevent interference with the first temperature sensor 101 when placing or taking food on the cooking accessory 40.
Referring to fig. 2-6, according to one specific embodiment of the present invention, a control method of an oven is provided,
The oven is provided with a first mounting part 51, a second mounting part 52 and a third mounting part 53 at intervals from top to bottom in sequence, and the first mounting part 51, the second mounting part 52 and the third mounting part 53 are used for placing the cooking accessory 40.
The control method comprises the following steps:
Firstly, judging whether a cooking accessory 40 is placed in the baking cavity 11, and if no baking tray exists, respectively accommodating a first one-temperature sensor 1011 and a first two-temperature sensor 1012 in a first accommodating part 131 and a second accommodating part 132;
If the baking tray is put in, firstly judging the placement position of the cooking accessory 40 positioned at the uppermost layer of the cooking accessory 40, if the uppermost layer of the cooking accessory 40 is put in the position of the first mounting part 51, judging the main temperature sensor as a second first temperature sensor 1021, if the uppermost layer of the cooking accessory 40 is positioned at the position of the second mounting part 52, judging the main temperature sensor as a first temperature sensor 1011, and if the uppermost layer of the cooking accessory 40 is positioned at the position of the third mounting part 53, judging the main temperature sensor as a first second temperature sensor 1012;
Judging whether the temperature control command is in an independent temperature control mode, if the temperature control command is in a non-independent temperature control mode, keeping the temperature sensor judged as the main temperature sensor in a state of extending into the baking cavity 11, for example, keeping the first one-to-one temperature sensor 1011 and the first two-temperature sensor 1012 unchanged in the second position if the second one-to-one temperature sensor 1021 is the main temperature sensor, controlling the first one-to-one temperature sensor 1011 to move to the first position if the first one-to-one temperature sensor 1011 is the main temperature sensor, keeping the first two-temperature sensor 1012 unchanged in the second position, and controlling the first two-temperature sensor 1012 to move to the first position if the first two-temperature sensor 1012 is the main temperature sensor, and keeping the first one-to-two temperature sensor 1011 unchanged in the second position;
When the temperature control is the independent temperature control mode, the placement position of the lowest cooking accessory 40 in the placed cooking accessory 40 is judged, if the lowest cooking accessory 40 is placed in the position of the first mounting portion 51, the first one-temperature sensor 1011 is judged to be the sub-temperature sensor, if the lowest cooking accessory 40 is placed in the position of the second mounting portion 52, the first two-temperature sensor 1012 is judged to be the sub-temperature sensor, if the lowest cooking accessory 40 is placed in the position of the third mounting portion 53, the second two-temperature sensor 1022 is judged to be the sub-temperature sensor, and the main temperature sensor and the sub-temperature sensor are simultaneously controlled to be moved to the first position to maintain the state of being extended into the baking chamber 11, and if the first one-temperature sensor 1011 or the first two-temperature sensor 1012 is neither the main temperature sensor nor the sub-temperature sensor, the first two-temperature sensor 1012 is accommodated in the accommodating portion 13.
Specifically, when in the non-independent temperature control mode, the main temperature sensor is used as a sensor for reacting the temperature of the furnace core, in the algorithm, the temperature of the main temperature sensor and the temperature of the furnace core are in one-to-one mapping relation, and the target value is quickly and accurately reached by utilizing the PID algorithm, and in the independent temperature control mode, the first heating element and the second heating element are separately controlled, the second heating element is controlled by feeding back the temperature through the main temperature sensor, and the first heating element is controlled by feeding back the temperature through the secondary temperature sensor.
For example, in one specific embodiment, when a user is cooking a small cake, the first one-temperature sensor or the first two-temperature sensor is in the second position before cooking begins, the small cake is placed on the baking pan, the baking pan with the small cake is placed in the oven, the independent temperature control mode is set, the second heating element 220 ℃, the first heating element 160 ℃, cooking begins, the first one-temperature sensor and the first two-temperature sensor are in the first position, cooking ends, and the first one-temperature sensor and the first two-temperature sensor return to the second position.
