Description
Technical Field

Background
At present, an electric heating tube is welded or riveted on a metal disc, or the metal disc is die-cast by taking the electric heating tube as a core. The electrothermal tube takes a metal tube as a shell, spiral heating wires are uniformly distributed along the axial direction of the center in the tube, and gaps of the electrothermal tube are filled with magnesia with good insulating and heat conducting properties. The electric heating tube cannot completely cover the metal disc due to the limitation of bending radius and other factors of the electric heating tube. Therefore, the heat is concentrated, the temperature of the electric heating tube and the covered area thereof is higher, the temperature of the surrounding area is lower, the metal disc is unevenly heated, and the temperature of the connecting terminal of the electric heating tube is higher. Therefore, the heating effect is not ideal, the thermal power density of unit area is not high, a large heat dissipation space is required to be reserved for the wiring terminal, the overall height of the cooking utensil is high, the product volume is increased, the user experience is affected, and a series of problems such as production material cost and the like are also wasted.
An electrothermal film is proposed in application 201911244488.1, which consists of an electrothermal film body and a metal wrapping sheet. The electrothermal film main body is an insulating film covered on the two sides of the heating wire, and the metal wrapping sheet clamps the electrothermal film main body therein. The metal wrapping sheet can be formed by folding the metal sheet in half, flattening the metal flat tube, riveting or welding the upper metal sheet and the lower metal sheet. The electric heating film has good heat dissipation effect and can solve the problems of the electric heating disc. In the application process, it is found that a certain thickness is required for the electrothermal disk to achieve necessary strength, and as the thickness of the metal wrapping sheet increases, the probability of the adhesion degree between the electrothermal film main body and the metal wrapping sheet becoming worse increases, because after the metal wrapping sheet becomes thicker, the uncertainty of processing flatness increases, and the riveting or welding force of the upper and lower metal sheets is insufficient to eliminate uneven places. The poor degree of laminating seriously influences the heat dissipation of electric heat membrane main part and the performance of electric heat dish.
