Problems solved by technology

Due to the fact that the technical solution does not inductively heat the bottom of the ceramic liner, most of the current electromagnetic rice cookers or induction cookers with electromagnetic coils placed at the bottom have relatively large magnetic resistance and are not very practical.

Abstract

The invention discloses a safety-type electromagnetic induction heating nonmetal pot which can be independently applied to heating an electromagnetic cooker or used as an electromagnetic-induction type electric rice cooker liner. The safety-type electromagnetic induction heating nonmetal pot comprises a ceramic or glass nonmetal pot body and a metal casing, wherein the metal casing takes the shape of a bucket or a basin and is at least provided with a magnetic induction metal layer at the outer bottom part; and the metal casing covers the bottom and partial or whole lateral part outside the nonmetal pot body, wherein at least partial position is closely covered without an air layer remain. The invention has the beneficial effects of simple process, attractive appearance, fast cooking speed, high thermal efficiency, safety, reliability, and the like and is suitable for large-batch industrial production and all-sided popularization and application.

Description

technical field [0001] The invention relates to a cooking utensil applied to electromagnetic induction heating, in particular to a safe electric cooker which can be individually applied to electromagnetic oven heating or used as an inner tank of an electromagnetic induction rice cooker, with large heating area, fast heating speed, not easy to burst, and energy saving. Magnetic induction heats non-metallic pans. Background technique [0002] Non-metallic pots and utensils such as purple sand, ceramics, and glass will not produce harmful aluminum ions and peel off non-stick coatings, and have a unique cooking style that returns to nature. , stews, pot of traditional Chinese medicine and so on. The non-metal pots that are widely used at present are resistive heating, but the thermal efficiency of the method is not high enough, and the heating speed is relatively slow. The induction cooker and electromagnetic rice cooker using electromagnetic heating are considered to have hig...
