[0027] As Figure 1 shown, a cooking device includes a pot body 10 and a heating device 20. The heating device 20 is disposed on the outer periphery of the pot body 10, matches the shape of the pot body 10, and there is a preset distance between the heating device 20 and the outer periphery of the pot body 10. The value range of the preset distance is 15 mm - 20 mm.

[0028] The heating device 20 of the cooking device is provided on the outer periphery of the pot body 10. The shape of the heating device 20 matches the shape of the pot body 10, and a preset distance is provided between the heating device 20 and the outer periphery of the pot body 10. The value range of the preset distance is 15 mm - 20 mm. In this way, when the heating device 20 heats the pot body 10, under the action of the preset distance, the heat conduction between the heating device 20 and the pot body 10 can be reduced, which can not only ensure the heating effect of the heating device 20 on the pot body 10, but also improve the service life of the heating device and even the entire cooking device.

[0029] As Figure 2 and Figure 3 shown, the heating device 20 includes a fixing frame 24 and a heating element 22. The fixing frame 24 covers the outside of the pot body 10, and the heating element 22 is fixed on the fixing frame 24. In the embodiment of the present application, it means that the value range of the distance between the outer diameter of the pot body and the inner diameter of the heating element 26 is 15 mm - 20 mm. The heating element 22 is arranged on the outer periphery of the pot body 10 through the fixing frame 24 to heat the pot body 10.

[0030] The heating element 22 is a circular structure or an oval structure formed by a heating wire coiled around the fixing frame 24. When the heating wire is wound around the fixing frame 24, it adheres to the fixing frame 24 and winds. The winding method can adopt a radiation winding as Figure 2 or Figure 3 shown to form a circular or oval heating wire heating area; or the bracket adopts a loop winding to form a heating wire heating area with a circular or oval contour. No matter which winding method is used, it should be noted that when winding, the wire winding should be smooth and without sharp corners. The highest point of the heating element 22 should not be too high (too close to the upper edge of the pot body 10) to avoid the occurrence of dry burning of the pot body. The width of the heating element 22 (i.e., in the circumferential direction of the pot body 10) is not limited and can be increased as much as possible according to needs to increase the heating area of the pot body 10 and improve the heating efficiency.

[0031] The heating element 22 includes a cylindrical surface that matches the shape of the upper part of the pot body, and a cylindrical surface or a spherical surface that matches the shape of the lower part of the pot body 10. When the pot body 10 is a cylindrical structure from top to bottom, the upper part of the surface of the heating element 22 formed by coiling the heating wire that is close to the pot body is a cylindrical structure that matches the shape of the pot body 10, and the lower part of the surface of the heating element 22 that is close to the pot body is a cylindrical structure that matches the shape of the pot body 10. When the shape of the pot body 10 is a spherical kettle type structure, it can be understood that the spherical kettle type structure is formed by combining an upper part, a cylindrical structure, and a lower part of a spherical structure. Then, an adaptive change is made to the upper part of the surface of the heating element 22 that is close to the pot body, that is, the shape of the upper part of the surface of the heating element 22 that is close to the pot body is set as a cylindrical surface, and the lower part of the surface of the heating element 22 that is close to the pot body 10 is set as a spherical surface. In this application, by varying the shape of the pot body 10 and the shape of the heating element 22 accordingly, it is ensured that the distance between the heating element 22 and the pot body 10 is equal, maintaining the stability of heating.

[0032] In this embodiment, the fixing frame 24 includes an upper fixing frame 242 and a lower fixing frame 244 arranged up and down. The upper fixing frame 242 matches the shape of the upper part of the pot body 10, and the lower fixing frame 244 matches the shape of the lower part of the pot body 10. When the pot body 10 is a cylindrical structure from top to bottom, both the upper fixing frame 242 and the lower fixing frame 244 are cylindrical structures that match the shape of the pot body 10, that is, the surface of the upper fixing frame 242 that is close to the pot body 10 is a cylindrical surface, and the surface of the lower fixing frame 244 that is close to the pot body 10 is also a cylindrical surface. When the shape of the pot body 10 is a spherical kettle type structure, it can be understood that the spherical kettle type structure is formed by combining an upper part, a cylindrical structure, and a lower part of a spherical structure. Then, the shape of the upper fixing frame 242 that cooperates with the cylindrical structure of the pot body 10 is set as a cylindrical surface, and the shape of the lower fixing frame 244 that cooperates with the spherical structure of the pot body 10 is set as a spherical surface. In this application, by varying the shape of the pot body 10 and making a segmented design of the fixing frame 24, and thus varying the shape of the heating element 22 fixed to the fixing frame, it is ensured that the distance between the heating element 22 and the pot body 10 is equal, maintaining the stability of heating.

[0033] At least one side of the fixing frame 24 is provided with a fixing edge 266, and at least one fixing hole 268 is provided on the fixing edge 266. Fixing members such as screws and bolts pass through the fixing hole 268 to fix the fixing frame 24 to the pot body assembly, that is, the fixing frame 24 is fixed to the outer periphery of the pot body 10 of the cooking device.

[0034] The material of the fixing bracket 24 is made of heat-resistant material, preferably engineering plastics or heat-resistant plastics such as nylon. During the operation of the heating device 20, the fixing bracket 24 will not be affected by its service life due to the long-term high-temperature working environment.

[0035] As Figure 4 shown, the heating device 20 further includes a shielding cover 28, and the shielding cover 28 surrounds the outer periphery of the heating device 20. Shielding cover fixing edges extend from both sides of the shielding cover 28, and shielding cover fixing holes are formed in the shielding cover fixing edges. Fixing members such as bolts or screws pass through the shielding cover fixing holes to fix the shielding cover to the pot body assembly. The shielding cover 28 can well surround the heating element 22 and even the entire heating area to achieve electromagnetic field shielding and prevent the heating element 22 from heating the metal outer shell outside it. Preferably, the shielding cover 28 is of a segmented structure or an arc-shaped structure to adapt to the arc-shaped outer periphery of the pot body, and its height is equivalent to the height of the heating element 22. The shielding cover 28 is made of a material with good conductivity, preferably materials with good electrical conductivity such as aluminum, copper and their alloys.

[0036] The material of the fixing bracket 24 is made of heat-resistant material. Preferably, materials such as engineering plastics or nylon are used.
