[0023] As shown in FIG. 1, the cooking device comprises a pot body 10 and a heating device 20, the heating device 20 is provided on the outer periphery of the pot body 10, and there is a predetermined distance between the heating device 20 and the outer periphery of the pot body 10 to match the shape of the pot body 10, and the value of the predetermined distance ranges from 15 mm to 20 mm.

[0024] The heating device 20 of the cooking device is provided on the outer periphery of the pan body 10, the shape of the heating device 20 matches the shape of the pan body 10, and there is a predetermined distance between the heating device 20 and the outer periphery of the pan body 10, the predetermined distance ranging from 15mm to 20mm. In this way, when the heating device 20 heats the pan body 10, the heat conduction between the heating device 20 and the pan body 10 can be reduced under the action of the predetermined distance, ensuring the heating effect of the heating device 20 on the pan body 10 and extending the service life of the heating device and the entire cooking device.

[0025] 2 and 3, the heating device 20 includes a fixed frame 24 and a heating member 22, the fixed frame 24 is covered on the outside of the pot body 10, and the heating member 22 is fixed to the fixed frame 24. In the embodiment of the present application, the value of the distance between the outer diameter of the pot body and the inner diameter of the heating member 26 ranges from 15 mm to 20 mm. The heating member 22 is disposed on the outer periphery of the pot body 10 via the fixed frame 24, and the pot body 10 is heated.

[0026] The heating element 22 has a circular or elliptical structure formed by winding a heating wire around the fixed frame 24. When winding the heating wire around the fixed frame 24, the heating wire is wound tightly around the fixed frame 24, and the winding method is adopted to wind the heating wire radially to form a circular or elliptical heating wire heating area, or to wind the heating wire around the bracket to form a heating wire heating area with a circular or elliptical outline, as shown in FIG. 2 or FIG. 3. Whatever winding method is selected, it is necessary to wind smoothly without corners. In order to avoid the pan body from being boiled dry, the highest position of the heating element 22 should not be too high (too close to the upper edge of the pan body 10). The width of the heating element 22 (i.e., in the circumferential direction of the pan body 10) is not limited and can be as wide as necessary to increase the heating area of ​​the pan body 10 and improve the heating efficiency.

[0027] The heating element 22 includes a cylindrical surface conforming to the shape of the upper part of the pot body, and a cylindrical or spherical surface conforming to the shape of the lower part of the pot body 10. When the pot body 10 has a columnar structure from top to bottom, the upper part of the surface of the heating element 22 close to the pot body, which is formed by winding a heating wire, has a columnar structure conforming to the shape of the pot body 10, and the lower part of the surface of the heating element 22 close to the pot body has a columnar structure conforming to the shape of the pot body 10. When the shape of the pot body 10 is a spherical pot structure, the spherical pot structure is formed by combining a columnar structure at the upper part and a spherical structure at the lower part, and the upper part of the surface of the heating element 22 close to the pot body is adaptively changed, that is, the shape of the upper part of the surface of the heating element 22 close to the pot body is set to a cylindrical surface, and the lower part of the surface of the heating element 22 close to the pot body 10 is set to a spherical surface. In the present application, the shape of the heating element 22 is adjusted according to the different shapes of the pot body 10, the distance between the heating element 22 and the pot body 10 is equalized, and the stability of heating is maintained.

When the pot body 10 has a columnar structure from top to bottom, the upper fixing frame 242 and the lower fixing frame 244 are both columnar structures adapted to the shape of the pot body 10, i.e., the surface of the upper fixing frame 242 close to the pot body 10 is a cylindrical surface, and the surface of the lower fixing frame 244 close to the pot body 10 is also a cylindrical surface. When the pot body 10 has a spherical shape, it can be understood that the spherical shape is formed by combining an upper cylindrical structure and a lower spherical structure, and the shape of the upper fixing bracket 242 adapted to the columnar structure of the pot body 10 is a cylindrical surface, and the shape of the lower fixing frame 244 adapted to the spherical structure of the pot body 10 is a spherical surface. In the present application, the fixed frame 24 is designed in segments according to different shapes of the pan body 10, the shape of the heating element 22 fixed to the fixed frame is adjusted, the distance between the heating element 22 and the pan body 10 is made equal, and the heating stability is maintained.

[0029] At least one side of the fixing frame 24 is provided with a fixing edge 266, and the fixing edge 266 is provided with at least one fixing hole 268. A fastener such as a screw or a bolt is passed through the fixing hole 268 to fix the fixing frame 24 to the pan body assembly, i.e., the fixing frame 24 is fixed to the outer periphery of the pan body 10 of the cooking apparatus.

[0030] The fixing frame 24 is made of a heat-resistant material, preferably a heat-resistant plastic such as engineering plastic or nylon, etc. When the heating device 20 is in operation, the life of the fixing frame 24 will not be affected by a long-term high-temperature environment.

[0031] As shown in FIG. 4, the heating device 20 further includes a shield cover 28 surrounding the outer periphery of the heating device 20. Shield cover fixing edges extend from both sides of the shield cover 28, and the shield cover fixing edges are provided with shield cover fixing holes, through which fasteners such as bolts or screws pass to fix the shield cover to the pan body assembly. The shield cover 28 can effectively surround the heating element 22 and even the entire heating area, so as to shield the electromagnetic field and prevent the heating element 22 from heating its outer metal shell. Preferably, the shield cover 28 has a segmented structure or a circular arc structure to fit the circular arc outer periphery of the pan body, and its height is approximately equal to that of the heating element 22. The shield cover 28 is made of a material having good electrical conductivity, preferably a material having good electrical conductivity such as metal aluminum, copper and their alloys.

[0032] The fixed frame 24 is made of a heat-resistant material, and is preferably made of a heat-resistant plastic such as engineering plastic or nylon.
