[0037] The third temperature control component 300 is installed corresponding to the heating tube 440 and senses the temperature of the heating tube 440;
[0038] When the air heat transfer rice cooker is in use, the first temperature control component 100 detects the temperature of the top of the pot 420, the second temperature control component 200 detects the temperature of the bottom of the pot 420, and the third temperature control component 300 detects the temperature of the heating tube 440. The heating temperature is detected from three different positions through the three-point temperature control structure, thereby achieving the purpose of precise temperature control.
[0039] Furthermore, an electronic board is provided in the air heat transfer rice cooker, and the first temperature control component 100, the second temperature control component 200 and the third temperature control component 300 are all electrically connected to the electronic board, and the temperature signals detected by the first temperature control component 100, the second temperature control component 200 and the third temperature control component 300 are all transmitted to the electronic board, and after being analyzed by the electronic board, the heating power of the heating tube 440 is controlled according to a preset program on the electronic board;
[0040] If a plurality of heating tubes 440 are provided in the air heat transfer rice cooker, the operating number and operating power of the heating tubes 440 can be controlled.
[0041] In one embodiment, the first temperature control component 100 includes: a first probe 110 and a first mounting bracket 120; the first mounting bracket 120 is assembled in the inner cover 411 of the pot cover 410, the first mounting bracket 120 is hollow, the first probe 110 extends downward through the first mounting bracket 120, and the temperature of the top of the pot 420 is detected by the first probe 110.
[0042] Specifically, the first temperature control component 100 is installed at the center of the pot cover 410. The pot cover 410 has an inner cover 411. The inner cover 411 is provided with a hole for assembling the first mounting bracket 120. The first mounting bracket 120 is a silicone bracket. The first mounting bracket 120 is sealed with the inner wall of the hole to prevent steam from entering the gap between the inner cover 411 and the outer cover of the pot cover 410 through the hole.
[0043] In one embodiment, the second temperature control component 200 includes:
[0044] The second mounting bracket 220 is mounted on the first cover 430;
