Abstract

The invention discloses an electromagnetic cooking appliance and a detection method thereof, wherein the electromagnetic cooking appliance includes an insulated gate bipolar transistor, the insulated gate bipolar transistor is used to drive the electromagnetic cooking appliance to heat, and the electromagnetic cooking appliance detects The method includes the following steps: acquiring the current opening width and current detection value of the IGBT; acquiring the first current threshold of the IGBT according to the opening width; comparing the current detection value and the first current threshold; when the current detection value is less than or equal to the first current threshold, reduce the heating power of the electromagnetic cooking appliance, and / or generate a prompt signal to prompt the existence of the electromagnetic cooking appliance abnormal. The technical scheme of the invention improves the safety of the electromagnetic cooking utensil.

Description

technical field [0001] The invention relates to the technical field of cooking, in particular to an electromagnetic cooking utensil and a detection method thereof. Background technique [0002] Most of the pot bases of existing electromagnetic cooking appliances are made of acrylonitrile-butadiene-styrene copolymer or polypropylene plus glass fiber material, and the highest temperature resistance of the pot base is usually about 200°C. When the electromagnetic cooking appliance is abnormally dry, the temperature at the bottom of the heated pot will rise sharply, which may exceed the maximum temperature that the pot base can withstand. Or, when heating a pot with a small bottom area, the temperature may rise sharply due to the small bottom area of ​​the pot and slow heat dissipation. In the existing electromagnetic cooking utensils, the temperature of the heated pot is detected by the temperature sensor. However, due to the slow time response of the temperature sensor, the m...
