Abstract

The invention provides an electromagnetic heating appliance and a temperature measuring device and a temperature measuring method thereof. The electromagnetic heating appliance comprises a choking coil, a first power tube and a second power tube, wherein the first power tube is connected with the choking coil through the second power tube. The temperature measuring device comprises: a first thermistor welded on a circuit board and used for collecting the temperature of a first power tube; and a second thermistor welded on the circuit board and used for collecting the temperature of a second power tube. The temperature measuring device of the electromagnetic heating appliance is simple in processing technology and low in cost.

Description

technical field [0001] The invention relates to the technical field of electrical appliances, in particular to a temperature measuring device of an electromagnetic heating appliance, a temperature measuring method of the electromagnetic heating appliance and an electromagnetic heating appliance with the temperature measuring device. Background technique [0002] At present, in an induction cooker with a half-bridge topology, since two power tubes (IGBT, Insulated Gate Bipolar Transistor) are used, and the power tube is a heat-generating device, the main control chip needs to detect the temperature of the IGBT in real time during the heating process to prevent When abnormal, the IGBT is overheated and burned. Therefore, two sets of temperature measuring circuits are generally used for temperature measurement, including thermistors, resistors, capacitors, etc., and thermistors generally measure temperature through flexible support frames in contact with the IGBT body, resultin...
