Electromagnetic heating cookware and three-dimensionally heated electromagnetic cooking appliance

Abstract

The invention relates to an electromagnetic heating cookware and a three-dimensionally heated electromagnetic cooking appliance. The electromagnetic heating cookware is formed by stretching aluminum plates and is a cylindrical cookware with a bottom. The cookware comprises a pot body, a pot bottom, a transition part and a magnetic conduction heating element which is embedded into the outer side of the transition part, wherein the transition part is connected with the pot body and the pot base; the transition part is arc; the heat conduction heating element is a metal stretching net with a high extending property; the metal stretching net is compressed and connected to the corresponding part of the aluminum plate in advance and is stretched and formed into a cookware together with the aluminum plate. The three-dimensionally heated electromagnetic cooking appliance comprises a shell, the cookware and an electromagnetic wire coil for inducing the cookware to be heated three-dimensionally; the cookware is the cookware for electromagnetic heating; and the electromagnetic cooking appliance is an electric cooker, or an electric pressure cooker or an electric stewpan.

Description

technical field [0001] The invention relates to the field of household kitchen appliances, in particular to a pot for electromagnetic heating and an electromagnetic cooking appliance with three-dimensional heating of the pot. Background technique [0002] Aluminum pots in the prior art are widely used in household kitchen appliances such as electric rice cookers, electric pressure cookers, and electric saucepans. Such pots conduct heat quickly, heat evenly, and are usually made of deep-drawn aluminum plates with low cost. Because the aluminum material is a non-magnetic material, this inner pot cannot be used directly on an electromagnetic heating appliance. However, with the continuous development and progress of science and technology, new heating stoves such as induction cookers have widely entered ordinary households, and Aluminum pots alone cannot be used on induction cookers, which will inevitably limit their competitiveness in the market. For this reason, scientific an...

AI Technical Summary

Problems solved by technology

Due to the large difference in elongation between the aluminum plate and the steel plate, the joint between the two plates is the weakest at the transition part during the stretching process. When the pot is abnormally dry, the problem of bursting will easily occur at this point.
