[0002] Electric heating cooking utensils are household appliances that directly heat the cooker through the principle of heating by electricity through the heating tube. Common ones include electric fryers, electric rice cookers, electric pressure cookers, etc. Electric heating cooking utensils in the prior art include heating components such as heating tubes and heating plates. The heating tubes and the heating plates can be integrally formed or manufactured separately and then combined. The heating tube is arranged at the bottom of the heating plate. When electricity is applied, the heating plate heats the heating plate, which in turn heats the pot body. The heating plate needs to be connected to the heat preservation cover in the cooking utensils by screws to achieve installation and fixation. However, the manufacturing cost of the structure in which the heating tube and the heating plate are integrally formed is relatively high, and the installation structure manufactured separately and then combined is relatively complex and inconvenient to assemble, which reduces the production efficiency of the cooking utensils.

[0003] Therefore, it is necessary to provide a heating assembly and a cooking appliance to at least partially solve the above problems. Utility Model Content

However, it will be apparent to those skilled in the art that the present application can be implemented without one or more of these details. In other examples, some technical features well known in the art are not described in order to avoid confusion with the present application.

[0059] In order to thoroughly understand the present application, a detailed description will be provided in the following description. It should be understood that these embodiments are provided to make the disclosure of the present application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. Obviously, the implementation of the embodiments of the present application is not limited to the specific details familiar to those skilled in the art. The preferred embodiments of the present application are described in detail below, but in addition to these detailed descriptions, the present application may also have other embodiments.

[0060] Ordinal numbers such as “first” and “second” cited in this application are merely identifiers and do not have any other meanings, such as a specific order, etc. Moreover, for example, the term “first component” itself does not imply the existence of a “second component”, and the term “second component” itself does not imply the existence of a “first component”.

[0061] It should be noted that the terms "upper", "lower", "front", "back", "left", "right", "inside", "outside" and similar expressions used in this application are for illustrative purposes only and are not restrictive.

[0062] The present application discloses a heating assembly for a cooking appliance and a cooking appliance having the same.

[0063] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings.

[0064] like Figure 1 、 Figure 2 As shown, in a preferred embodiment, the heating assembly of the present application is used in a cooking appliance 100, and the heating assembly includes: a heating plate 40, a heating tube 50 and a heat preservation cover 30;

[0065] The heating plate 40 is used to directly contact the pot body 10 of the cooking utensil 100 and transfer heat to the pot body 10, thereby heating the pot body 10 and thus heating the food in the pot body 10. The heating plate 40 can be made of aluminum stamping, which can significantly reduce the manufacturing cost compared to die casting.

[0066] The heating tube 50 is provided at the bottom of the heating plate 40. When the heating tube 50 is energized, it can generate heat and transfer the heat to the heating plate 40.

[0067] The heat-insulating cover 30 is used to accommodate the pot body 10 of the cooking utensil 100. The heat-insulating cover 30 is arranged around the pot body 10 and can reflect the heat generated by the pot body 10 back to the pot body 10, isolating the heat generated by the pot body 10 from escaping and preventing the pot body 20 from overheating. This not only improves the heat-insulating effect of the pot body 10, but also improves the safety of the cooking utensil 100.

[0068] The heating plate 40 and the heating tube 50 are fixedly connected by welding, and the heating plate 40 and the heat preservation cover 30, and / or the heating tube 50 and the heat preservation cover 30 are fixedly connected by welding.

[0069] The heating assembly in this embodiment is formed by manufacturing the heating plate 40 and the heating tube 50 separately and then welding them together. The heating plate 40 and / or the heating tube 50 are welded together with the heat insulation cover 30, which can facilitate the assembly between the components. Compared with the integral die-casting of the heating plate 40 and the heating tube 50, and the connection of the heating plate 40 and the heat insulation cover 30 by screws, the manufacturing cost can be reduced, the assembly process can be simplified, and the production efficiency of the cooking appliance 100 can be improved.

[0086] Brazing is used to securely connect the heating plate 40 to the heating tube 50, and to securely connect the heating plate 40 and / or the heating tube 50 to the heat-insulating cover 30. Because brazing has a relatively low melting point, the brazing material can be pre-laid, facilitating the welding of complex structures, thin-walled components, and components made of different materials. The brazing material can be selected from alloys such as aluminum-based, magnesium-based, copper-based, silver-based, manganese-based, gold-based, nickel-based, palladium-based, and tantalum-based alloys.

The second top surface 52 of the heating tube 50 is flush with the support step 31, ensuring that the heating tube 50, the support step 31, and the heating plate 40 are well integrated during the brazing process.

[0091] By fitting the second bottom surface 53 of the heating tube 50 to the bottom surface 34 of the heat preservation cover 30 , a welding structure is conveniently provided on the second bottom surface 53 of the heating tube 50 , thereby achieving a welded fixed connection between the heating tube 50 and the heat preservation cover 30 .
