Inner pot for electromagnetic induction heating cooker and processing method thereof

Abstract

The invention discloses an inner pot for an electromagnetic induction heating cooker and a processing method thereof, relates to the technical field of electromagnetic induction heating cooking and solves the problem in the prior art of low magnetism conduction efficiency. The inner pot for the electromagnetic induction heating cooker comprises a pot body of the inner pot, wherein a magnetism conduction sheet is composited at the bottom on the outer side of the pot body. Meshes are arranged on the magnetism conduction sheet, pot body materials are deformed and extruded into the meshes, the magnetism conduction sheet is fixedly composited at the bottom of the pot body, a joint is formed between the edge of the magnetism conduction sheet and the pot body, a magnetism conduction layer is arranged outside the pot body and the magnetism conduction sheet, formed in high temperature meltallizing mode and covered on the joint position, and the magnetism conduction sheet at the joint position is tightly embedded into the pot body in the high temperature meltallizing process. The inner pot for the electromagnetic induction heating cooker is mainly used in the electromagnetic induction heating cookers, in particular to electric pressure cookers, electric cooker, electric saucepans and the like which are in electromagnetic induction heating.

Description

technical field [0001] The invention relates to the technical field of electromagnetic induction heating cooking, in particular to an inner pot for an electromagnetic induction heating cooker and a processing method thereof. Background technique [0002] Cooking appliances such as rice cookers and electric pressure cookers heated by electromagnetic induction, their working principle is: a high-frequency current is passed through the electromagnetic coil, so that a high-frequency alternating magnetic field is generated around the electromagnetic coil, and the alternating magnetic field can cause eddy currents to be generated on the inner pot , through the function of the eddy current, the inner pot itself can generate heat, so as to carry out heating and cooking. [0003] With the continuous development of electromagnetic induction heating technology, this type of cooker is becoming more and more popular at present. In order to realize electromagnetic heating, the inner pot g...

AI Technical Summary

Problems solved by technology

[0005] In the process of realizing and using the above-mentioned inner pot, the inventor found at least the following problems in the prior art: the solution of using a metal composite plate to directly stretch out the inner pot needs to use a whole piece of composite plate, and the upper part of the inner but side part Generally, electromagnetic heating is not required, which results in waste of magnetically conductive stainless steel and high cost of the inner pot; the inner pot made by fusion spraying is easy to be oxidized during the high-temperature spraying process of the magnetically conductive metal layer. The efficiency of magnetic conduction is low, and the heating efficiency of magnetic conduction electromagnetic induction heating cooker is low
