Abstract

The invention discloses an electromagnetic heating cooking utensil and an IGBT overheating abnormity treatment method and device. The IGBT overheating abnormity treatment method includes the followingsteps: when the electromagnetic heating cooking utensil heats, obtaining the temperature of an IGBT in real time; judging the temperature of the IGBT to generate a judgement result; controlling the heating power of the electromagnetic heating cooking utensil to decrease step by step when obtaining that overheating abnormity of the IGBT occurs, wherein reference temperature for judging the temperature of the IGBT is increased step by step when controlling the heating power of the electromagnetic heating device to decrease step by step. The IGBT overheating abnormity treatment method of the embodiments of the invention can perform buffer treatment when the IGBT is about to overheat, and can fully judge whether the temperature of the IGBT can support continuous work instead of simply controlling the electromagnetic heating cooking utensil to stop heating, and makes the self-recovery of the IGBT overheating abnormity possible.

Description

technical field [0001] The present invention relates to the technical field of household appliances, in particular to a method for processing abnormal overheating of IGBT in an electromagnetic heating cooking appliance, a non-temporary computer-readable storage medium, a device for processing abnormal overheating of IGBT in an electromagnetic heating cooking appliance, and a method An electromagnetic heating cooking appliance having the IGBT overheating abnormal processing device. Background technique [0002] At present, IGBT (Insulated Gate Bipolar Transistor, Insulated Gate Bipolar Transistor), as the core component of the IH heating system, needs to be monitored and protected during work. [0003] In related technologies, a conventional method is to set a certain fixed temperature value, and when the temperature of the IGBT is higher than this temperature, the heating operation is stopped. However, this method is too simple, and does not give the possibility of self-rec...
