The arrangement of the structure effectively solves the problem that the cooking utensil cannot be normally used because a user reversely installs the pot body 20 in the related art.

The above-mentioned "at least a part of the first handle 22 is disposed in the first limiting recess 11" means that a part of the first handle 22 may be located in the first limiting recess 11 or the whole of the first handle 22 may be located in the first limiting recess 11. Accordingly, the above-mentioned "at least a part of the second handle 23 is disposed in the second limiting recess 12" means that a part of the second handle 23 may be located in the second limiting recess 12 or the whole of the second handle 23 may be located in the second limiting recess 12.

Fig. 1-3 show the related structure of the first embodiment of the pot body assembly according to the present application. In the first technical solution of the embodiment, the temperature sensing element 30 is disposed on the first handle 22, and the temperature sensing part of the temperature sensing element 30 extends into the pot body 20. The first wireless module 41 is disposed on the first handle 22 and below the temperature sensing element 30; the second wireless module 42 is disposed inside the pot body 10 and fixed below the first wireless module 41 by the inner wall of the pot body 10 and the bracket 13.

In the process of loading the pot body 20, the user can smoothly place the pot body 20 into the pot body 10 by matching the fool-proof groove 51 with the fool-proof protrusion 52. If the user puts the pan body 20 reversely, the first handle 22 is put into the second limit concave part 12, and the second handle 23 is put into the first limit concave part 11. Because the first handle 22 does not have a corresponding groove to match with the fool-proof protrusion 52, the fool-proof protrusion 52 will prop against the lower surface of the first handle 22, so that the first handle 22 is higher than the second handle 23, and the whole pot body 20 is inclined and cannot be installed in place. The arrangement of the fool-proof structure 50 effectively avoids the situation that the temperature signal transmitted by the temperature sensing element 30 cannot be received by the transmission device 40, which results in the failure of accurate temperature measurement, when the pot body 20 is reversely installed by a user in the installation process.

In other embodiments, the fool-proof groove may also be disposed in the second limiting recess, and correspondingly, the fool-proof protrusion is disposed on the second handle. The structure can also effectively prevent the user from reversely mounting the pot body in the mounting process.

The arrangement of the arc-shaped ribs and the arc-shaped grooves is adapted to the circumferential profiles of the cooker body 10 and the cooker body 20, so that the fool-proof structure 50 can give consideration to the fool-proof effect and the manufacturing cost. Meanwhile, the convex rib and groove structure has the advantages of simple process, reliable structure and low processing cost.

As shown in fig. 4, in the present embodiment, the fool-proof protrusion 52 is disposed in the second limiting recess 12, the fool-proof groove 51 is disposed in the second handle 23, and two ends of the fool-proof protrusion 52 are connected to the opposite sidewalls of the second limiting recess 12. The sidewall of the fool-proof protrusion 52 is connected to the sidewall of the second limiting recess 12, so that the fool-proof protrusion 52 fully utilizes the circumferential length of the second limiting recess 12, the length of the fool-proof protrusion 52 is increased, the strength of the fool-proof protrusion 52 and the strength of the fool-proof structure 50 are improved, and the connection is reliable. When the cover is rotated, the fool-proof protrusion 52 can also play a role in stabilizing the pot body 20, so that the pot body 20 is prevented from moving when the cover body 60 is rotated.

In this embodiment, the fool-proof protrusion 52 is an arc-shaped rib, and the fool-proof groove 51 is a groove adapted to the arc-shaped rib. It should be noted that the cooperation of the protrusion and the groove with other shapes is within the protection scope of the present application as long as the second handle can be prevented from being installed in the first limiting concave portion and the first handle is prevented from being installed in the second limiting concave portion.

During the installation process, if the user reversely installs the pot body 20, the sensing element 54 does not sense the magnetic element 53, and the controller will send out a prompt signal. The prompt signal comprises a light prompt, a sound prompt and the like, and a user can know that the pot body 20 is reversely assembled after receiving the prompt signal, so that the user can correctly assemble the pot body.

As shown in fig. 9 and 10, the sensing member 54 is disposed below the second stopper recess 12, and the magnetic member is disposed on the second handle 23. The sensing member 54 is disposed below the second limiting recess 12, i.e. when properly installed, the sensing member 54 is located below the magnetic member 53, and can sense the magnetic member 53. If a user reversely installs the pot body 20 during the installation process, the first handle 22 is put into the second limit concave part 12, and the second handle 23 is put into the first limit concave part 11. So that the first handle 22 is above the sensing element 54, the sensing element 54 does not sense the magnetic element 53, and the user is prompted.

In this embodiment, the magnetic member 53 is a magnet, and the inductive member 54 is a reed switch. The magnet and the reed switch are common components and parts, can be directly purchased, and have various types for selection, and the cost is low.
