[0002] Some existing cooking appliances generally include a base, an inner pot is placed on the base, a heating cavity is formed between the bottom of the inner pot and the inner cavity bottom of the base, a heating device is fixed to the bottom of the inner pot, and the heating device heats in the heating cavity to heat the inner pot for cooking food; a heat insulation plate needs to be arranged in the base to separate the heat in the heating cavity from other electronic components in the base, so as to prevent the normal operation of other components from being affected due to excessive temperature.

[0003] When the existing heat insulation plate is insulating heat, since it is in the high-temperature heating cavity for a long time, it has a certain amount of heat while insulating heat. In order to prevent the side wall of the base from melting due to high temperature, a gap is provided between the heat insulation plate and the inner wall of the base. However, when the soup in the inner pot leaks out during use, it is easy to enter the bottom of the base along the inner wall of the base along this gap, which will not only affect the operation of the internal components, but also be inconvenient to clean; or other components are added to the edge of the heat insulation plate to achieve the heat insulation effect, but the manufacturing cost is increased, which is not conducive to production and manufacturing.

[0017] The embodiment of this application provides a heat insulation structure for a cooking appliance, which is used to solve the technical problems that the heat insulation structure of the existing cooking appliance is unreasonably arranged and not convenient for production and manufacturing.

[0018] In order to make the invention object, features, and advantages of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the embodiments described below are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present application.

[0019] Please refer to Figures 1 to 3 The embodiment of the present application provides a base heat dissipation structure for an induction cooker. The cooking appliance includes a base 100 and an inner pot 200. A heating device 210 is provided at the bottom of the inner pot 200; the inner pot 200 is hung on the edge of the base 100, and a heat insulation plate 300 is installed on the base 100 below the inner pot 200; the heat insulation plate 300 is fixed in the inner cavity of the base 100, and a limiting edge 310 is provided by folding the edge of the heat insulation plate 300, and the limiting edge 310 is in contact with the inner wall of the base 100; the connection between the side wall and the bottom of the heat insulation plate 300 is arc-shaped; a plurality of groups of heat dissipation holes 320 are arranged circumferentially along the limiting edge 310, and the groups of heat dissipation holes 320 are formed by densely distributing a plurality of heat dissipation holes 321.

[0020] Specifically, a heating coil is fixed on the bottom of the inner pot 200 to heat the inner pot 200 for cooking food. A terminal is provided on the base 100. The inner pot 200 is hung on the base 100, and the heating coil is inserted into the terminal for heating. The heat insulation plate 300 is installed at the bottom of the base 100, so that a heating cavity is formed between the inner pot 200 and the heat insulation plate 300. Other components are provided below the heat insulation plate 300 on the base 100. Through the heat insulation effect of the heat insulation plate 300, the heat in the heating cavity is prevented from being conducted to other components to affect normal operation. The heat insulation plate 300 is made of a metal material with good heat dissipation effect. In this embodiment, the heat insulation plate 300 is made of galvanized sheet, which has a certain heat radiation effect, can preferably reflect the heat of the heating device back to the side of the inner pot 200, has poor heat conduction effect and good heat dissipation effect, and ensures heat insulation effect while having sufficient structural strength. The edge of the heat insulation plate 300 is folded horizontally to form a limiting edge 310. The contour of the limiting edge 310 is consistent with the inner wall contour of the base 100 and abuts against the inner wall of the base 100. Under the abutment of the limiting edge 310, it plays a role of limiting and supporting the base 100 in the horizontal direction. Multiple groups of heat dissipation hole groups 320 are formed on the limiting edge 310, and a heat dissipation fence hole is provided at the bottom of the bottom, so that heat can be exchanged through the heat dissipation holes 321 to reduce the temperature of the limiting edge 310, and the situation of melting glue when the limiting edge 310 abuts against the side wall of the base 100 can be prevented. The heat insulation plate 300 has a certain height, and the connection between the side walls around it and the bottom is arc-shaped, so that a larger cavity is formed under the limiting edge 310 at the bottom of the heat insulation plate 300, which can increase the heat exchange efficiency between cold air and the heat in the heated cavity and improve the heat dissipation effect. The heat insulation plate 300 in this embodiment has a simple and reasonable structure and is convenient for production and manufacturing.

[0021] Further, a convex fixing plate 110 is provided on one side wall of the inner cavity of the base 100. The limiting edge 310 is provided with a limiting groove 311 at a position adapted to the fixing plate 110, and the limiting groove 311 is clamped to the limiting plate. A convex fixing plate 110 is provided on one side of the inner wall of the base 100 near the rear side. The fixing plate 110 is used to fix the feet of the base 100. The limiting edge 310 forms an avoiding limiting groove 311 at the corresponding position. The limiting groove 311 is docked with the fixing plate 110, which is also convenient for positioning during installation. Heat dissipation hole groups 320 are provided at the corners of both sides of the limiting edge 310 near the limiting groove 311; Heat dissipation hole groups 320 are provided at the middle parts of the adjacent two sides and the opposite side of the limiting groove 311 of the limiting edge 310; The width of the limiting edge 310 at the limiting groove 311 is smaller. By arranging heat dissipation hole groups 320 on both sides of the limiting groove 311, it is ensured that the limiting edge 310 has a good heat dissipation effect on this side. Heat dissipation hole groups 320 are provided in the middle of the other three sides of the limiting edge 310 except the limiting groove 311. This area is relatively close to the heating coil area, ensuring good heat dissipation effect while ensuring the structural strength of the limiting edge 310.

[0022] Still further, the heat dissipation holes 321 are in a runway shape. The heat dissipation hole group 320 is formed by arranging a plurality of heat dissipation holes 321 in a runway shape, increasing the area of the heat dissipation holes 321 and improving the efficiency of heat exchange.

[0023] Even further, a strip-shaped reinforcing rib 330 is convexly provided in the middle of the heat insulation disc 300. The rear side of the bottom of the heat insulation disc 300 is the installation area of the wiring terminal. A strip-shaped reinforcing rib 330 is convexly formed in the middle, and both ends of the reinforcing rib 330 are bent towards the opposite sides respectively, corresponding to the wiring terminal and other protrusions at the bottom, further strengthening the structural strength.

[0024] Specifically refer to Figure 3 , a plurality of fixing columns 120 are provided on the base 100, and fixing holes 312 are provided on the limiting edge 310. The fixing holes 312 are fixed to the fixing columns 120 by threaded connection. The position of the fixing holes 312 is close to the heat dissipation hole group 320. Fixing columns 120 extend from the front side and the rear side of the bottom of the inner cavity of the base 100. Fixing holes 312 are provided at the corresponding positions of the limiting edge 310. The fixing holes 312 are adjacent to the heat dissipation hole groups 320 on the front and rear sides of the limiting edge 310, ensuring that the temperature at the fixing holes 312 is relatively low and not likely to cause the fixing columns 120 to deform due to high temperature. The fixing holes 312 and the fixing columns 120 are fixed by screws or studs, etc., making the installation of the heat insulation disc 300 stable.
