Abstract

The invention discloses an electromagnetic heating cooking appliance and its IGBT overheating abnormal processing method and device. The IGBT overheating abnormal processing method includes the following steps: when the electromagnetic heating cooking appliance is heating, the temperature of the IGBT is obtained in real time; The temperature of the electromagnetic heating cooker is judged to generate a judgment result; when it is known that the IGBT is overheated abnormally according to the judgment result, the heating power of the electromagnetic heating cooking appliance is controlled to decrease step by step, wherein, in the process of controlling the heating power of the electromagnetic heating cooking appliance The reference temperature for judging the temperature of the IGBT is gradually increased. The IGBT overheating abnormality processing method of the embodiment of the present invention can perform buffer processing when the IGBT is about to overheat, and can fully determine whether the temperature of the IGBT can support continued work, instead of simply controlling the electromagnetic heating cooking appliance to stop heating, so that the IGBT Overheating abnormality has the possibility of self-recovery.

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-recov...
