An induction cooker and its heating control circuit, and automatic/semi-automatic cooking equipment

Abstract

The invention discloses an induction cooker, a heating control circuit thereof and automatic / semi-automatic cooking equipment, wherein the heating control circuit comprises a coil driving circuit and a control signal generating circuit connected with the coil driving circuit, the control signal generating circuit comprises a storage unit which is used to store control parameter variation curves; according to the control parameter variation curves read from the storage unit, the control signal generating circuit generates a control signal and then outputs the control signal to the coil driving circuit so as to control the coil driving circuit to drive the induction cooker to output the corresponding heat power. The heating control circuit provided by the invention can well control the heating process of the induction cooker, thus the application scope of the induction cooker can be broader.

Description

technical field [0001] The invention relates to an electromagnetic oven, a heating control circuit thereof, and automatic / semi-automatic cooking equipment for electromagnetic heating. Background technique [0002] As a new cooking tool, induction cooker is increasingly accepted by people. Unlike traditional cooking tools, such as gas stoves, which use open fire cooking methods, induction cookers use the principle of electromagnetic induction to generate high-frequency alternating current through the components of the electronic circuit board and apply it to the electromagnetic coil. When the induction cooker is equipped with a pan (usually an iron-containing pan) placed on the induction cooker, the pan cuts the alternating magnetic force line and generates an alternating current, that is, an eddy current, in the metal part of the bottom of the pan. The eddy current makes the iron molecules of the pan move at high speed and irregularly, and the molecules collide and rub again...

AI Technical Summary

Problems solved by technology

[0003] In the existing heating process of cooking materials using induction cooker, when it is necessary to use different heats to heat materials, it is basically manual operation, and it is up to the operator to judge based on experience, at what stage, what kind of cooking method should be used. Heat, according to different cooking methods (such as frying, roasting, frying, etc.) way needs
