For example, such terms may indicate a fixed connection, a movable connection, or a detachable connection; may indicate a mechanical connection or an electrical connection; and may indicate direct interconnection, indirect interconnection through an intermediate medium, or internal communication between two elements. Those of ordinary skill in the art may understand specific meanings of the foregoing terms in the present application based on a specific situation.

As shown in FIG. 1, a cooking device comprises a pot body 10 and a heating apparatus 20, wherein the heating apparatus 20 is arranged at an outer periphery of the pot body 10 and matches a shape of the pot body 10, a preset distance is provided between the heating apparatus 20 and the outer periphery of the pot body 10, and the preset distance ranges from 15 mm to 20 mm.

The heating apparatus 20 of the cooking device is arranged at the outer periphery of the pot body 10, a shape of the heating apparatus 20 matches the shape of the pot body 10, a preset distance is provided between the heating apparatus 20 and the outer periphery of the pot body 10, and the preset distance ranges from 15 mm to 20 mm. In this way, when the heating apparatus 20 heats the pot body 10, the preset distance can reduce the heat conduction between the heating apparatus 20 and the pot body 10, which can not only ensure the heating effect of the heating apparatus 20 on the pot body 10, but also increase the service life of the heating apparatus and even the entire cooking device.

As shown in FIGS. 2 and 3, the heating apparatus 20 comprises a fixing frame 24 and a heating member 22, the fixing frame 24 is covered on an outer side of the pot body 10, and the heating member 22 is fixed on the fixing frame 24. In the embodiment of the present application, a distance between an outer diameter of the pot body and an inner diameter of the heating member 26 ranges from 15 mm to 20 mm. The heating member 22 is arranged on the outer periphery of the pot body 10 through the fixing frame 24 to heat the pot body 10.

The heating member 22 is a circular structure or an elliptical structure formed by coiling a heating wire on the fixing frame 24. When being wound on the fixing frame 24, the heating wire is attached to and wound on the fixing frame 24, and the winding mode can adopt a radiation type winding mode as shown in FIG. 2 or FIG. 3 to form a circular or elliptical heating wire heating area; or a bracket is wound in a circle to form a circular or elliptical heating wire heating area. In any winding mode, the winding needs to be smooth without edges and corners. The highest point of the heating member 22 should not be too high (too close to the upper edge of the pot body 10), so that the phenomenon of dry burning of the pot body is avoided. The width of the heating member 22 (i.e., the direction around the circumference of the pot body 10) is not limited, and can be increased as much as possible based on a requirement to increase the heating area of the pot body 10 and improve the heating efficiency.

The heating member 22 comprises a cylindrical surface matching a shape of an upper part of the pot body and a cylindrical or spherical surface matching a shape of a lower part of the pot body 10. When the pot body 10 is a cylindrical structure from top to bottom, an upper part of one surface of the heating member 22 formed by coiling the heating wire close to the pot body is a cylindrical structure matching the shape of the pot body 10, and a lower part of one surface of the heating member 22 close to the pot body is a cylindrical structure matching the shape of the pot body 10. When the shape of the pot body 10 is a spherical kettle-shaped structure, it can be understood that the spherical kettle-shaped structure is formed by combining the cylindrical structure of the upper part and the spherical structure of the lower part, and then the upper part of one surface of the heating member 22 close to the pot body is adaptively changed. That is, the shape of the upper part of one surface of the heating member 22 close to the pot body is configured as a cylindrical surface, and the shape of the lower part of one surface of the heating member 22 close to the pot body 10 is configured as a spherical surface. The present application ensures the same distance between the heating member 22 and the pot body 10 by designing the shape of the heating member 22 according to different shapes of the pot body 10, thereby maintaining the stability of heating.

In this embodiment, the fixing frame 24 comprises 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, an upper fixing frame 242 and a lower fixing frame 244 are both cylindrical structures matching the shape of the pot body 10. That is, one surface of the upper fixing frame 242 close to the pot body 10 is a cylindrical surface, and one surface of the lower fixing frame 244 close to the pot body 10 is also a cylindrical surface. When the shape of the pot body 10 is a spherical kettle-shaped structure, it can be understood that the spherical kettle-shaped structure is formed by combining the cylindrical structure of the upper part and the spherical structure of the lower part, then the shape of the upper fixing frame 242 matching the cylindrical structure of the pot body 10 is configured as a cylindrical surface, and the shape of the lower fixing frame 244 matching the spherical structure of the pot body 10 is configured as a spherical surface. The present application designs the fixing frame 24 in sections according to the different shapes of the pot body 10, thereby changing the shape of the heating member 22 fixed on the fixing frame, which ensures the same distance between the heating member 22 and the pot body 10 and maintains the stability of heating.

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 holes 268 to fix the fixing frame 24 and the pot body assembly. That is, the fixing frame 24 is fixed on the outer periphery of the pot body 10 of the cooking device.

The fixing frame 24 is made of a heat-resistant material, preferably engineering plastics or nylon or other heat-resistant plastics. When the heating apparatus 20 is working, the serve life of the fixing frame 24 will not be affected by the long-term high-temperature working environment.

As shown in FIG. 4, the heating apparatus 20 further comprises a shield cover 28, wherein the shield cover 28 surrounds an outer periphery of the heating apparatus 20. Shield cover fixing edges extend from two sides of the shield cover 28, shield cover fixing holes are provided on the shield cover fixing edges, and fixing members such as screws and bolts pass through the shield cover fixing holes to fix the shield cover and the pot body assembly. The shield cover 28 can well surround the heating member 22, and even the entire heating area, to shield electromagnetic fields and prevent the heating member 22 from heating the metal shell outside the heating member. Preferably, the shield cover 28 is a segmented structure or an arc-shaped structure to adapt to the outer periphery of the arc-shaped pot body, and the height of the shield cover is equivalent to the height of the heating member 22. The shield cover 28 is made of a material with good electrical conductivity, preferably a material with good electrical conductivity such as metal aluminum, copper and alloys thereof.

The fixing frame 24 is made of a heat-resistant material. Preferably, engineering plastics, nylon or the like are adopted.
