[0002] As the pace of people's lives accelerates, more and more people are looking for cooking appliances that can automatically cook food, freeing up their hands and providing convenient and quick cooking. Microcomputer-controlled cooking appliances can cook food automatically without human intervention, and they can be used for multiple purposes with one pot, saving effort and producing no smoke, making them popular with an increasing number of users.

[0003] In conventional technology, heating devices for pot bodies generally use a heating coil to heat the pot body and generate heat through electromagnetic induction. However, the heat radiation from the pot body, i.e., the heat generated by the heating coil itself, increases the temperature of the heating coil and affects the lifespan of the coil and fixing frame. Therefore, when heating the pot body, it is difficult to control the temperature, which affects the lifespan of the heating device. Summary of the Invention [Problem to be solved by the invention]

[0023] As shown in Figure 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 apparatus is mounted on the outer periphery of the pot body 10, and the shape of the heating device 20 matches the shape of the pot body 10. There is a predetermined distance between the heating device 20 and the outer periphery of the pot body 10, and the predetermined distance ranges from 15 mm to 20 mm. In this way, when the heating device 20 heats the pot body 10, the predetermined distance reduces heat conduction between the heating device 20 and the pot body 10, ensuring the heating effect of the heating device 20 on the pot body 10 and extending the service life of the heating device and the entire cooking apparatus.

[0025] 2 and 3, the heating device 20 includes a fixing frame 24 and a heating element 22. The fixing frame 24 is enclosed by the outside of the pot body 10, and the heating element 22 is fixed to the fixing frame 24. In the present embodiment, the distance between the outer diameter of the pot body and the inner diameter of the heating element 26 ranges from 15 mm to 20 mm. The heating element 22 is disposed on the outer periphery of the pot body 10 via the fixing 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 tightly wound around the fixed frame 24. This winding method can be radial, as shown in Figures 2 or 3, to form a circular or elliptical heating area, or it can be wrapped around a bracket to form a circular or elliptical heating area. Regardless of the winding method, care must be taken to ensure a smooth winding without sharp corners. To prevent the pot from heating empty, the highest position of the heating element 22 should not be too high (too close to the upper edge of the pot body 10). The width of the heating element 22 (i.e., in the circumferential direction of the pot body 10) is not limited and can be as wide as necessary to increase the heating area of ​​the pot body 10 and improve heating efficiency.

[0027] The heating element 22 has a cylindrical surface conforming to the shape of the upper part of the pot body 10 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 heating element 22, which is formed by winding a heating wire, closest to the pot body has a columnar structure conforming to the shape of the pot body 10, and the lower part of the heating element 22 closest to the pot body has a columnar structure conforming to the shape of the pot body 10. When the pot body 10 has a spherical structure, the spherical structure is formed by combining a columnar structure at the upper part with a spherical structure at the lower part, and the upper part of the heating element 22 closest to the pot body is adaptively changed, i.e., the shape of the upper part of the heating element 22 closest to the pot body is set to a cylindrical surface, and the lower part of the heating element 22 closest to the pot body 10 is set to a spherical surface. In this 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 heating stability is maintained.

[0028] In this embodiment, the fixing frame 24 comprises an upper fixing frame 242 and a lower fixing frame 244 arranged one above the other, with the upper fixing frame 242 conforming to the shape of the upper part of the pot body 10 and the lower fixing frame 244 conforming to the shape of the lower part of the pot body 10. If the pot body 10 has a columnar structure from top to bottom, the upper fixing frame 242 and the lower fixing frame 244 both have columnar structures conforming to the shape of the pot body 10. That is, the surface of the upper fixing frame 242 closest to the pot body 10 is cylindrical, and the surface of the lower fixing frame 244 closest to the pot body 10 is also cylindrical. If the pot body 10 has a spherical structure, the spherical structure can be understood as being formed by combining an upper cylindrical structure with a lower spherical structure. The shape of the upper fixing frame 242 conforming to the columnar structure of the pot body 10 is cylindrical, and the shape of the lower fixing frame 244 conforming to the spherical structure of the pot body 10 is spherical. In this application, the fixed frame 24 is designed to be segmented according to different shapes of the pot body 10, and the shape of the heating element 22 fixed to the fixed frame is adjusted to equalize the distance between the heating element 22 and the pot body 10, thereby maintaining heating stability.

[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 bolt is passed through the fixing hole 268 to fix the fixing frame 24 to the pan body assembly, i.e., 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 operating, 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 are inserted to secure the shield cover to the pot body assembly. The shield cover 28 effectively surrounds the heating element 22 and even the entire heating area to shield electromagnetic fields and prevent the heating element 22 from heating its outer metal shell. Preferably, the shield cover 28 has a segmented or arc-shaped structure that fits the arc-shaped outer periphery of the pot body, and its height is approximately equal to that of the heating element 22. The shield cover 28 is formed of a highly conductive material, preferably aluminum, copper, or an alloy thereof.

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

[0033] The above is merely a description of preferred embodiments of the present application and the technical principles applied thereto. Those skilled in the art will understand that the present application is not limited to the specific embodiments described herein, and that various obvious modifications, adjustments, and substitutions can be made by those skilled in the art without departing from the scope of protection of the present application.
