Description

Technical Field

[0001] This utility model belongs to the field of heating plate technology and relates to a heating container with high thermal conductivity. Background Technology

[0002] In daily life, some appliances that require heating (such as kettles and rice cookers) usually have a heating plate installed inside. Heat is conducted through contact between the heating plate and the container being heated. Currently, existing heating plates are typically flat, meaning the container contacts the bottom surface of the heating plate during heating. While this structure is simple and easy to implement, it also has certain drawbacks. Specifically, a flat heating plate only contacts the container through its bottom surface, resulting in a limited heating area, low heat transfer efficiency, and a longer heating time. Furthermore, a flat heating plate tends to cause uneven heating, with the bottom area of ​​the container getting excessively hot while the upper areas remain cool, affecting the overall performance. Utility Model Content

[0003] The purpose of this invention is to provide a heating container with high thermal conductivity to solve the problems of limited heating area, low heat conduction efficiency, and long heating time of existing planar heating plates mentioned in the background art.

[0005] A heating container with high thermal conductivity includes a shell and a heating plate, wherein the heating plate is installed inside the shell, and the heating plate includes:

[0006] A heating base plate, with a heating element installed at its bottom;

[0007] A heating side plate is located at the edge of the heating base plate, and its outer end extends outward along the axis of the heating base plate.

[0008] The heating base plate and the heating side plate are integrally stretched and formed, and the heating base plate and the heating side plate surround each other to form an installation cavity with an opening.

[0009] Preferably, the heating base plate has a disc-shaped structure.

[0010] Preferably, the lower surface of the heating base plate is provided with a connecting post, the height of which is greater than the thickness of the heating tube.

[0011] Preferably, the heating tube is coiled in an arc shape around the bottom surface of the heating base plate, and the vertical distance from any point on the center line of the arc to the central axis of the heating base plate is equal.

[0012] Preferably, the outer edge of the heating side plate is folded outward horizontally to form a connecting ring, and the connecting ring extends into the annular groove opened in the side wall of the outer shell.

[0013] Preferably, it also includes a kettle body, which is made of glass, and the lower end of the kettle body can extend into the mounting cavity formed by the heating base plate and the heating side plate.

[0014] Preferably, it also includes a rubber ring installed on the top of the outer shell, the inner edge of which extends toward the center of the outer shell, and the inner wall of the rubber ring can contact the outer wall of the outer shell when the lower end of the pot is installed into the mounting cavity.

[0015] Preferably, the rubber ring has multiple slots that are arranged vertically through each other, and the slots extend from the middle of the upper end face of the rubber ring towards the inner wall.

[0016] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0017] This utility model has a simple and reasonable design structure. The heating plate is designed with a U-shaped cross-section, which allows the heated container to conduct heat not only through the bottom heating plate but also through the side heating plates to conduct heat to the side walls of the container during the heating process.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] As shown in the figure, a heating container with high thermal conductivity includes a shell 1 and a heating plate 4. The heating plate 4 is installed inside the shell 1 and includes:

[0030] A heating base plate 401 is provided, and a heating tube 405 is installed at its bottom. In this example, the heating base plate 401 is a disc-shaped structure. In other embodiments, the heating base plate 401 may also be designed as an elliptical or polygonal structure, which is not limited here.

[0031] Heating side plate 402 is located at the edge of heating base plate 401, and its outer end extends outward along the axis of heating base plate 401;

[0032] The heating base plate 401 and the heating side plate 402 are integrally stretched and formed, and the heating base plate 401 and the heating side plate 402 surround to form an open mounting cavity 403. In actual use, the kettle body 6 can be placed in the mounting cavity 403. On the one hand, the heating base plate 401 and the heating side plate 402 can contact the kettle body 6 to improve the heat conduction efficiency and heating effect. On the other hand, the structural design of the mounting cavity 403 can also prevent the heated container from easily detaching from the mounting cavity 403 when the kettle body 6 is docked with the heating plate 4.

[0033] Specifically, the lower surface of the heating base plate 401 is provided with a connecting post 406. The height of the connecting post 406 is greater than the thickness of the heating tube 405. This arrangement serves two purposes: firstly, the connecting post 406 is used to fix the heating plate 4; secondly, it is to prevent the lower surface of the heating tube 405 from contacting other components inside the appliance, thus preventing the components from being damaged by heat.

[0034] Specifically, the heating tube 405 is coiled in an arc shape around the bottom surface of the heating base plate 401, and the vertical distance from any point on the center line of the arc to the central axis of the heating base plate 401 is equal, in order to improve the uniformity of heating of the heating plate 4. The heating tube 405 can be a brazed heating tube, which is welded to the bottom of the heating base plate 401 by brazing process. After being powered on, it can conduct heat to the heating plate 4. Since the cross-sectional shape of the heating plate 4 is U-shaped, the container can not only be heated at the bottom, but the heat can also be conducted to the heating side plate 402, thereby achieving the effect of side heating.

[0035] Specifically, the outer edge of the heating side plate 402 is folded outward horizontally to form a connecting ring 404, which extends into the annular groove opened in the side wall of the outer shell 1 to axially limit the heating plate 4.

[0036] Specifically, it also includes a pot body 6, which is made of glass. The lower end of the pot body 6 can extend into the mounting cavity 403 formed by the heating base plate 401 and the heating side plate 402. In addition, in this embodiment, the heating container also includes a mounting plate 3 connected to the bottom of the heating plate 4, a temperature detection sensor, and an inner shell 2 disposed inside the outer shell 1. A top cover 7 is also provided on the top of the pot body 6. This part of the structure is a conventional setting in the prior art and will not be described in detail here.

[0037] Specifically, it also includes a rubber ring 5 installed on the top of the outer shell 1. The inner edge of the rubber ring 5 extends towards the center of the outer shell 1, and when the lower end of the pot body 6 is installed into the mounting cavity 403, the inner wall of the rubber ring 5 can contact the outer wall of the pot body 6. The design of the rubber ring 5 is mainly to prevent the pot body 6 from sliding after being placed into the mounting cavity 403. In addition, it can also keep the hot air in the mounting cavity 403 to prevent heat from dissipating outward, which is beneficial to improving the heat conduction efficiency. More specifically, the rubber ring 5 has multiple slots 501 that are arranged vertically through it. The slots 501 are arranged from the middle of the upper end face of the rubber ring 5 towards the inner wall, so that the pot body 6 can easily enter the mounting cavity 403.

[0038] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
