For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0029] The structure of the temperature sensor at the bottom of the pot, such as Figure 1-3 As shown, it includes: a probe 100 and a silicone bracket 200;

[0030] A contact plane 101 is provided on the top of the probe 100. The probe 100 is installed at the center of the silicone bracket 200 and the contact plane 101 of the probe 100 is exposed on the top of the silicone bracket 200. The silicone bracket 200 is wide at the bottom and narrow at the top to support the mounting surface on which it is assembled. The silicone bracket 200 provides axial elastic force for the probe 100.

[0031] When in use, the silicone bracket 200 is installed in the rice cooker, and the silicone bracket 200 is supported on the installation surface on which it is assembled. When the probe 100 is subjected to pressure from the inner pot 420 of the rice cooker, the probe 100 moves downward, and the silicone bracket 200 is compressed and deformed. The silicone bracket 200 provides an upward elastic force for the probe 200, so that the probe 100 is in good contact with the bottom of the inner pot 420.

[0032] Furthermore, the silicone bracket 200 is narrow at the top and wide at the bottom, and is arranged in a bowl shape, so as to wrap the probe 100 well.

[0033] In one embodiment, the silicone bracket 200 is hollow, and a hollow channel 201 is formed in the middle. The upper end of the hollow channel 201 is in close contact with the probe 100 to clamp the probe 100. The diameter of the lower end of the hollow channel 201 is larger than the diameter of the probe 100, and a reinforcing rib 210 is provided at the lower end of the hollow channel 201. The reinforcing rib 210 protrudes from the inner wall of the hollow channel 201 toward the center.

[0034] Furthermore, the silicone bracket 200 may be provided with bite marks at the upper end of the hollow channel 201 , so as to more closely fit with the probe 100 , clamp the probe 100 , and prevent relative movement between the silicone bracket 200 and the probe 100 .

[0035] Furthermore, the reinforcing rib 210 is integrally formed with the silicone bracket 200 , and the reinforcing rib 210 is provided to enhance the deformation capacity of the silicone bracket 200 so that the silicone bracket 200 can be better reset after deformation.

[0036] In one embodiment, the probe 100 includes: a first probe portion 110 and a second probe portion 120, wherein the second probe portion 120 is disposed on the top of the first probe portion 110, and the upper surface of the second probe portion 120 forms the contact plane 101; the diameter of the second probe portion 120 is greater than the diameter of the first probe portion 110;

[0037] Furthermore, a groove body for accommodating the second probe part 120 is provided on the top of the silicone bracket 200 , and the contact plane 101 is flush with the top of the silicone bracket 200 .

[0038] like Figure 3 As shown, the first probe part 110 and the second probe part 120 are assembled. After the assembly, the second probe part 120 is limited in the groove body, and the second probe 120 cannot move up and down relative to the silicone bracket 200.

[0039] Furthermore, the height of the probe 100 is greater than the height of the silicone bracket 200, and the end of the probe 100 passes through the silicone bracket 200, which is convenient for subsequent installation.

[0040] Air heat transfer rice cooker, such as Figure 4-5As shown, it includes: an outer shell 410 and an inner pot 420, and also includes a pot bottom temperature sensing probe structure.

[0041] A first cover 430 and a second cover 440 are further provided between the shell 410 and the inner pot 420. The pot bottom temperature sensing probe structure is installed on the first cover 430 and protrudes from the first cover 430. The silicone bracket 200 provides an upward elastic force for the probe 100 to make it closely contact the bottom of the inner pot 420.

[0042] like Figure 5 As shown, the pot bottom temperature sensing probe structure protrudes from the surface of the first cover body 430 after installation. When the inner pot 420 is installed, the gravity of the inner pot 420 acts on the pot bottom temperature sensing probe structure, so that the contact plane 101 of the probe 100 is closely fitted with the bottom surface of the inner pot 420.

[0043] like Figure 4 As shown, the bottom of the silicone bracket 200 is supported on the inner wall of the first cover 430, and the lower end of the probe 100 extends downward through the first cover 430, as shown in FIG. Figure 2 As shown, the probe 100 is further provided with a limiting portion 130, which is located outside the first cover body 430 and abuts against the outer bottom wall of the first cover body 430;

[0044] Continue as Figure 4 As shown, the silicone bracket 200 provides an upward elastic force for the probe 100. Since the limiter 130 is in conflict with the outer bottom surface of the first cover body 430, the probe 100 will not be pulled away from the first cover body 430 by the upward elastic force. On the contrary, under external force, the probe 100 can move downward, and the silicone bracket 200 is compressed; after the downward force applied to the probe 100 disappears, the elastic force of the silicone bracket 200 pushes the probe 100 to move upward and reset, which facilitates the upward and downward movement of the probe 100. The utility model uses the elastic force of the silicone bracket 200 to make the contact plane 101 better contact with the inner liner 420 to detect the bottom temperature of the inner liner 420.

[0045] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
