Abstract
The utility model discloses a tripping control circuit of an electric cooker, which belongs to the technical field of electric appliances. The tripping control circuit is formed by a power supply, a microcontroller, a temperature sensor and an IGBT (Insulated Gate Bipolar Transistor), wherein the temperature sensor is fixedly arranged on a thermistor, the output end of the temperature sensor is connected with the input end of the microcontroller, the output end of the microcontroller is connected with a grid electrode of the IGBT, one end of the IGBT is connected with a positive electrode of the power supply, the other end of the IGBT is connected with the thermistor, and the other end of the thermistor is connected with a negative electrode of the power supply. When the device works, the temperature of the thermistor can be detected by the temperature sensor, a signal can be sent to the microcontroller by the temperature sensor when the temperature exceeds a set value, a signal can be sent by the microcontroller for switching off the IGBT, thus a heating circuit can be switched off, and the tripping operation of the electric cooker can be realized. The tripping control circuit disclosed by the utility model has the advantages that the circuit performance is stable, the reliability is high, and the response speed is quick.
