[0005] In some embodiments, the mica heating plate has a circular horizontal cross-section, and the support plate has a circular horizontal cross-section.

[0006] In some embodiments, the bent edge is formed by stamping the through hole.

[0007] In some embodiments, the mica heating plate includes an upper cover, a base, and a heating component. The heating component is disposed between the upper cover and the base. The support plate extends downward from the edge of the upper cover. The heating component and the base are pressed between the rolled edge and the bottom surface of the upper cover.

[0008] In some embodiments, the heating element includes a mica plate and a heating wire, with both ends of the heating wire disposed in the pins and the middle portion of the heating wire wound around the mica plate.

[0009] In some embodiments, a drainage hole is provided on one side of the bent edge, which is lower than the bottom surface of the insulation cover.

[0010] Compared with the prior art, the beneficial effects of this application are as follows:

[0011] This application utilizes the bend on the insulation cover and the rolled edge at the bottom of the mica heating plate to fix the mica heating plate onto the insulation cover during assembly. The mica heating plate is placed on the through hole, and then the edge of the through hole is bent using hydraulic equipment. The assembly process is quick and easy, saving a lot of manpower and resources and improving assembly efficiency. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] refer to Figures 1 to 5 This application provides a mica heating plate fixing structure, including: a heat preservation cover 1 and a mica heating plate 2 disposed inside a rice cooker. The bottom of the mica heating plate 2 is provided with a pin 3. The middle of the heat preservation cover 1 is provided with a through hole 4 for the pin 3 to pass through. The edge of the mica heating plate 2 extends downward and is provided with a support plate 5. The bottom end of the support plate 5 extends inward and is provided with a rolled edge 6. The edge of the through hole 4 extends upward and is provided with a bent edge 7 for hooking the rolled edge 6.

[0019] In some embodiments, the horizontal cross-section of the mica heating plate 2 is circular, the horizontal cross-section of the support plate 5 is circular, that is, the horizontal cross-sections of the rolled edge 6 and the bent edge 7 are also circular, and the bent edge 7 can attach the hook to the rolled edge 6.

[0020] In some embodiments, the bent edge 7 is formed by stamping through the through hole 4.

[0021] In some embodiments, the mica heating plate 2 includes an upper cover 8, a base 9, and a heating component 10. The heating component 10 is disposed between the upper cover 8 and the base 9. A support plate 5 extends downward from the edge of the upper cover 8. The heating component 10 and the base 9 are pressed together between the rolled edge 6 and the bottom surface of the upper cover 8.

[0022] In some embodiments, the heating element 10 includes a mica plate and a heating wire, with both ends of the heating wire disposed in the pins 3 and the middle part of the heating wire wound around the mica plate.

[0023] In some embodiments, a drainage hole 11 is provided on one side of the bent edge 7, which is lower than the bottom surface of the insulation cover 1. When water overflows into the insulation cover 1, the water can be discharged through the drainage hole 11 on the insulation cover 1, thus avoiding short circuit.

[0024] The specific fixing process of this application is as follows: the mica heating plate 2 is placed upside down on the workbench (at this time, the pin 3 is facing upwards), and then the heat insulation cover 1 is placed upside down on the mica heating plate 2 (at this time, the through hole 4 is located inside the rolled edge 6). The edge of the through hole 4 is bent using hydraulic equipment, and the bent edge 7 is abutted against the hook and hung on the rolled edge 6 to complete the fixing of the mica heating plate 2.

[0025] This application utilizes the bend 7 on the insulation cover 1 to cooperate with the rolled edge 6 at the bottom of the mica heating plate 2. During the assembly process, the mica heating plate 2 only needs to be placed on the through hole 4, and then the edge of the through hole 4 is bent using hydraulic equipment to fix the mica heating plate 2 on the insulation cover 1. The assembly process is quick and simple, saving a lot of manpower and material resources and improving assembly efficiency.

[0026] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model.
