When the temperature measuring element 31 is installed, the temperature measuring element 31 can be placed into the accommodating groove 322 from the opening of the accommodating groove 322, so that the temperature measuring element 31 is more convenient to install. Specifically, a first lead hole 323 through which the lead 311 of the temperature measuring element 31 can pass is formed at the bottom of the accommodating groove 322 to facilitate the routing of the temperature measuring element 31, so that the plug terminal 312 connected to the end of the lead 311 of the temperature measuring element 31 is electrically connected to the circuit board 43. Of course, in other implementations, the first lead hole 323 may also be formed on the sidewall of the receiving groove 322.

Preferably, the temperature sensing end of the temperature measuring element 31 has a stopping flange 310, and the bottom surface of the stopping flange 310 abuts against the upper surface of the opening of the accommodating groove 322. Through setting up backstop flange 310, effectively spacing has been carried out temperature element 31, further guarantees that temperature element 31 can be with the pan good contact, and then has improved the accuracy of temperature measurement.

For example, the heat-conducting casing of the temperature measuring element 31 may be T-shaped, and the top of the T-shaped heat-conducting casing is formed as the above-mentioned stop flange 310, so as to abut against the outside of the notch of the accommodating groove, that is, the temperature collecting end of the temperature measuring element 31 is located outside the notch of the accommodating groove, so that the temperature collecting end is not lower than the upper surface of the panel 2, thereby ensuring that the temperature measuring element 31 can directly contact with the bottom of the pot.

Because the bottom surfaces of some pots are flat surfaces and the bottom surfaces of some pots are concave surfaces or non-flat surfaces which are concave upwards, the temperature collecting end of the temperature measuring element 31 extends out of the opening of the containing groove 322, so that the temperature collecting end of the temperature measuring element 31 is ensured to be reliably contacted with the bottom surfaces of the pots, the pans and the non-pans can be used on the induction cooker of the embodiment, and accurate temperature control is realized.

As shown in fig. 3 and 9, the bottom end of the main body of the elastic element 32 is open, and a part of the sidewall of the main body of the positioning element 33 extends into the main body of the elastic element 32 and is attached to the inner wall of the main body of the elastic element 32. Therefore, the positioning part 33 plays a certain supporting and limiting role in the radial direction of the elastic main body part, so that the elastic part 32 cannot move left and right easily, and the stability of the elastic part 32 is further improved.

The outer sidewall of the main body of the positioning member 33 has a second flange 332 extending outward, and the second flange 332 and the sidewall of the positioning member 33 together form a support platform 300 for supporting the elastic member 32. The supporting platform 300 supports and limits the elastic element 32, so that the stability of the elastic element 32 is further improved. Specifically, the first flange 321 of the elastic member 32 is located on the second flange 332 of the positioning member 33. The notch 333 and the detent can be provided on the second flange 332 of the positioning element 33.

Specifically, the main body of the positioning member 33 may be provided with a second lead hole 331 through which the lead 311 of the temperature measuring element 31 passes. That is, the lead wire 311 of the temperature measuring element 31 sequentially extends from the first lead hole 323 at the bottom of the accommodating groove 322 of the elastic element 32 and the second lead hole 331 of the positioning element 33, and is electrically connected to the circuit board 43, so that the wiring is convenient and neat. It can be understood that the first lead hole 323 and the second lead hole 331 can allow the lead 311 of the temperature measuring element 31 to pass through and also allow the plug terminal 312 at the end of the lead 311 of the temperature measuring element 31 to pass through, or the first lead hole 323 and the second lead hole 331 only allow the lead 311 to pass through, and after the lead 311 passes through, the plug terminal 312 is connected to the end of the lead 311.

Preferably, at least two connecting arms 111 are provided, and at least two connecting arms 111 are arranged at intervals along the circumferential direction of the fixing frame 10. The connection between the fixing frame 10 and the annular cover 110 is realized through at least two connecting arms 111, so that the fixing frame 10 can be reinforced from at least two positions, the stability of the fixing frame 10 is improved, the stability of the temperature measuring component 3 fixed on the fixing frame 10 is further ensured, a guarantee is provided for the good contact between the temperature measuring element 31 and a cookware, and the accuracy of temperature measurement is further improved. Moreover, when the pan was placed on panel 2, temperature element 31 contacted with the bottom of a boiler of pan, and the pan can produce decurrent pressure to temperature measuring component 3, and simultaneously, temperature measuring component 3 can produce pressure to a certain extent to mount 10, through setting up linking arm 111 to at least two, can strengthen mount 10 from two at least positions, makes mount 10 can not warp easily, has improved mount 10's structural strength and bearing capacity.

In the present embodiment, the connecting arms 111 are specifically two, and the two connecting arms 111 are respectively disposed on two sides of the fixing frame 10.

In particular, the cover 11 may be bonded to the panel 2. When the upper cover 11 and the fixing frame 10 are integrally formed, the whole of the upper cover 11 and the fixing frame 10 can be bonded on the panel 2 together, and the assembly is quicker and more convenient. Here, it is possible to select to bond only the ring cover 110 to the panel 2, or to bond only the holder 10 to the panel 2, or to bond both the ring cover 110 and the holder 10 to the panel 2. Specifically, a glue groove may be provided on the upper surface of the upper cover 11, and when connecting, glue is dispensed into the glue groove, and then the panel 2 is adhered above the upper cover 11.
