Description

Electromagnetic heat conduction structure of electromagnetic heating household utensils

Technical Field

The utility model relates to an electromagnetic heating device specifically is an electromagnetic heating household utensils's electromagnetism heat conduction structure.

Background

Along with the social development and the improvement of the living standard of people, the requirements of people on products are higher and higher, and the induction cooker is a household appliance which is very convenient to use and very wide in application, so that the induction cooker is more and more popular in the market. The heating principle of the induction cooker is as follows: the electromagnetic coil on the main machine generates an alternating magnetic field, when the bottom of the cookware containing iron is placed on the stove surface of the main machine, the cookware cuts alternating magnetic lines of force, and then alternating current (eddy current) is generated at the metal part at the bottom of the cookware, the eddy current enables iron molecules of the cookware to move irregularly at high speed, and the molecules collide and rub with each other to generate heat energy. However, since the metal ware releases harmful heavy metals when being used for boiling water for a long time, which is harmful to the health of users, and the metal ware is inconvenient to process, the metal ware is replaced by the clean non-metal ware made of glass, ceramics and the like on the market, but the non-metal ware cannot be heated by an electromagnetic oven, so that the bottom of the non-metal ware is adhered with a magnetic conduction film, and the electromagnetic heating ware made of the non-metal materials such as the glass, the ceramics and the like is favored. However, the existing magnetic conductive film is only limited to a silver film, and the silver film is easy to fall off after long-term use without a protective layer. For example, chinese patent document CN208114509U discloses an electromagnetic heating container, and specifically discloses an electromagnetic heating container including: a non-magnetic conduction vessel for splendid attire treat heating matter still includes magnetic conduction membrane and non-metallic protective layer, and the magnetic conduction membrane sets up on the surface of vessel bottom, and the protective layer covers on the one side that deviates from the vessel bottom at the magnetic conduction membrane, and the magnetic conduction membrane includes a plurality of magnetic stripes or a plurality of concentric magnetic conduction rings of leading, and it has the third protective layer to fill in the clearance between two adjacent magnetic stripes or two adjacent concentric magnetic conduction rings of leading. The magnetic conductive film is arranged on the outer surface of the bottom of the container body, and can bubble or even fall off due to high temperature after long-time use, and in practical application, the magnetic conductive film is only made of silver materials, so that the materials are limited.

Therefore, further improvements are needed.
