Specifically, for the non-contact temperature sensor 1, the infrared energy radiated by the cooker is detected to measure the temperature of the cooker. The non-contact temperature sensor 1 comprises a sensor body 10, the sensor body 10 extends along the up-down direction, an infrared sensing temperature piece 110 capable of receiving infrared energy is arranged in the sensor body 10, an infrared transmission part 120 is upwards arranged at the top end of the sensor body 10 corresponding to the infrared sensing temperature piece 110, when the cooker is placed on a gas stove, infrared energy radiated by the cooker can be received by the infrared sensing temperature piece 110 through the infrared transmission part 120, and further measurement of the temperature of the cooker is achieved.
Generally, the sensor body 10 is installed at the burner of the gas stove, when the gas stove works, the sensor body 10 is located in the high-temperature flame, and at this time, the sensor body 10 is roasted by the high-temperature flame and the high-temperature flue gas, so that the temperature of the infrared transmission part 120 of the sensor body 10 is increased, the infrared transmission part 120 radiates higher infrared energy, and the infrared temperature sensing element 110 located in the sensor body 10 is interfered to detect the infrared energy radiated by the cooker, so that the temperature measurement accuracy of the non-contact temperature sensor 1 is greatly reduced.
In order to improve the temperature measurement accuracy of the non-contact temperature sensor 1, in this embodiment, the non-contact temperature sensor 1 further includes a heat shield 20 disposed on the sensor body 10, the heat shield 20 extends along the up-down direction, the heat shield 20 is in a barrel shape, the upper end of the heat shield 20 is in an open arrangement, the upper end of the sensor body 10 penetrates through the lower end of the heat shield 20, and the upper end of the sensor body 10 is located in the heat shield 20. Thus, when the cooker is placed on the gas stove, the bottom of the cooker is abutted with the upper end of the heat shield 20 to form a relatively closed heat insulation cavity 200, so that the infrared transmission part 120 is positioned in the heat insulation cavity 200, and further, the infrared transmission part 120 is prevented from being directly subjected to the roasting of high-temperature flame and high-temperature flue gas, the temperature of the infrared transmission part 120 can be obviously reduced, the infrared energy radiated outwards by the infrared transmission part 120 is reduced, the infrared energy received by the infrared sensing part 110 is sourced from the cooker as far as possible, and the temperature measurement accuracy of the infrared sensing part 110 on the cooker is ensured.
The heat shield 20 is generally made of a high temperature resistant material, such as a metal material, e.g., copper, stainless steel, or a ceramic material. In some preferred embodiments, referring to fig. 3, the inner surface or the outer surface of the heat shield 20 is further coated with a heat reflection layer 230, and the heat reflection layer 230 blocks the infrared energy generated by the high temperature flame from radiating toward the support tube 130, so as to prevent the support tube 130 from absorbing a large amount of infrared energy to raise its temperature, and finally reduce the interference to the infrared sensing element 110.
The heat shield 20 may be secured to the sensor body 10 in a variety of ways, for example, the heat shield 20 may be secured to the sensor body 10 by welding, or the heat shield 20 may be removably mounted to the sensor body 10 by screws, snaps, interference fit, or the like.
According to the technical scheme, the heat shield 20 is arranged on the sensor body 10, the upper end of the sensor body 10 penetrates through the lower end of the heat shield 20, and the upper end of the sensor body 10 is positioned in the heat shield 20, so that when the cooker is placed on a gas stove, the bottom of the cooker is abutted with the upper end of the heat shield 20 to form the relatively closed heat-insulating cavity 200, and therefore the infrared transmission part 120 is positioned in the heat-insulating cavity 200, further, the infrared transmission part 120 is prevented from being directly roasted by high-temperature flame and high-temperature flue gas, the temperature of the infrared transmission part 120 can be obviously reduced, the infrared energy radiated outwards by the infrared transmission part 120 is reduced, the infrared energy received by the infrared sensing part 110 is sourced from the cooker as far as possible, the temperature measurement accuracy of the infrared sensing part 110 on the cooker is ensured, and finally the temperature measurement accuracy of the non-contact temperature sensor 1 on the cooker is ensured.
Further, in this embodiment, the sensor body 10 includes the support tube 130 and the fixing ring 140, where the support tube 130 is disposed along the vertical direction, the fixing ring 140 is fixedly installed in the support tube 130, the infrared temperature sensing element 110 is fixed on the fixing ring 140, by setting the fixing element, the infrared temperature sensing element 110 is fixed in the support tube 130, so that the infrared temperature sensing element 110 is prevented from directly contacting the support tube 130, the support tube 130 with higher temperature is prevented from heat transfer to the infrared temperature sensing element 110, and the temperature measurement interference of the support tube 130 to the infrared temperature sensing element 110 is reduced. An infrared transmitting portion 120 is disposed at the top end of the supporting tube 130, wherein the top end of the supporting tube 130 is generally open, so that infrared energy generated by the cooker can be radiated to the infrared sensing element 110.
In the above embodiment, the sensor body 10 may further include a guide bar 150 and an elastic member 160, wherein the guide bar 150 is slidably connected to the lower end of the support tube 130, and the support tube 130 may slide up and down with respect to the guide bar 150; the elastic member 160 is accommodated in the support tube 130, one end of the elastic member 160 abuts against the fixing ring 140, and the other end abuts against the guide rod 150. The fixed ring 140 is located above the guide rod 150, the elastic piece 160 is located between the guide rod 150 and the fixed ring 140, the guide rod 150 is installed at the burner of the gas stove, when the cooker is placed on the gas stove, the bottom of the cooker is abutted with the heat insulation cover 20, the elastic piece 160 is compressed under the action of the gravity of the cooker, and then the cooker presses the heat insulation cover 20 and the supporting tube 130 downwards, so that good contact between the heat insulation cover 20 and the cooker is guaranteed, and the cooker is prevented from being jacked up. It is understood that the elastic member 160 may be a spring, a shrapnel, or the like.
Further, in the embodiment, the top end of the support tube 130 is open, and the infrared transmitting portion 120 includes a light transmitting member 121 mounted at the open top end of the support tube 130 in a covering manner, wherein the light transmitting member 121 has a better transmission effect on infrared rays, so that infrared energy generated by the cooker can be ensured to be radiated onto the infrared sensing member 110. It can be appreciated that the transparent member 121 is generally high temperature glass, and has better heat resistance and infrared light transmission effect.
It should be noted that, by setting the light-transmitting member 121 to cover the opening at the top end of the supporting tube 130, the infrared sensing member 110 is prevented from being directly exposed, so as to prevent stains from falling on the surface of the infrared sensing member 110, and to influence the receiving of the stains to the infrared energy, thereby ensuring the normal operation of the infrared sensing member 110.
In this embodiment, the infrared sensing element 110 is preferably spaced from the light-transmitting element 121, so that the infrared sensing element 110 can more fully receive the infrared energy transmitted from the light-transmitting element 121.
In order to facilitate the installation of the transparent member 121, the top end of the supporting tube 130 extends radially outward along the top end to form an installation flange 131, the outer circumferential surface of the installation flange 131 extends upward to form a limit flange 132, and the outer circumferential surface of the transparent member 121 abuts against the limit flange 132, so that the transparent member 121 and the supporting tube 130 are installed and fixed.
Further, in order to facilitate the installation of the heat shield 20 on the support tube 130, the lower end of the heat shield 20 is provided with an installation via hole 210 corresponding to the support tube 130, an annular installation flange 220 extends upwards along the hole edge of the installation via hole 210, and the annular installation flange 220 is sleeved and fixed on the outer circumferential surface of the support tube 130. The annular mounting flange 220 may be fixed to the support tube 130 by welding, or the annular mounting flange 220 is sleeved on the outer peripheral surface of the support tube 130 in an interference manner.
In the above embodiment, the upper end surface of the annular mounting flange 220 preferably abuts against the mounting flange 131, and at this time, the heat shield 20 can be relatively positioned with the top end of the support tube 130 through the annular mounting flange 220, so that the mounting height of the heat shield 20 relative to the support tube 130 is relatively fixed, so as to facilitate the consistency of assembly between the heat shield 20 and the support tube 130.
When the infrared transmitting portion 120 is positioned in the heat insulating chamber 200, the infrared transmitting portion 120 is not higher than the upper end surface of the heat shield 20. In the embodiment of the present invention, in order to avoid the infrared transmitting portion from abutting against the cooker, the infrared transmitting portion 120 is lower than the upper end surface of the heat shield 20, i.e. a gap is provided between the infrared transmitting portion 120 and the cooker.
It can be understood that when the light-transmitting member 121 is disposed at the top end of the supporting tube 130, if the light-transmitting member 121 contacts with the cooker, the surface of the light-transmitting member 121 is easily scratched, which results in a reduction of the transmission effect of the light-transmitting member 121 to the infrared rays, thereby affecting the receiving of the infrared energy by the infrared temperature sensing member 110 and affecting the accuracy of the non-contact temperature sensor 1 in measuring the temperature of the cooker. When the infrared transmission part 120 is lower than the upper end surface of the heat shield 20, a gap is formed between the light-transmitting member 121 and the cooker, so that the contact between the cooker and the light-transmitting member 121 can be avoided, the transmission effect of the light-transmitting member 121 on infrared rays is further ensured, and the temperature measurement accuracy of the infrared sensing member 110 is ensured.
The invention also provides a gas stove which comprises a non-contact temperature sensor, wherein the specific structure of the non-contact temperature sensor refers to the embodiment, and as the gas stove adopts all the technical schemes of all the embodiments, the gas stove has at least all the beneficial effects brought by the technical schemes of the embodiments, and the detailed description is omitted.
The foregoing description is only of the preferred embodiments of the present invention and is not intended to limit the scope of the invention, and all equivalent structural changes made by the description of the present invention and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the invention.
