When the cooker cover is covered with the cooker body, the thermistor is connected with the thermistor under the condition that an external power supply structure is electrified, the controller 5 acquires that the resistance value of the thermistor 31 changes, the controller 5 can think that the top heating device 11 is connected at the moment, and when a cooking function needs to be operated, the L/N line control switch 51 can be closed; when the cooker cover 1 and the cooker body 2 are not covered, the thermistor is not electrified, the resistance value is not changed, the controller considers that the top heating device 11 is not connected at the moment, and the L/N line control switch is disconnected and closed. The principle is that the power supply of the top heating device is determined by the control switch on the bottom main machine. Only when the control switch is closed, the terminal block can be supplied with commercial power, and the commercial power is supplied to the top heating device 11 after passing through the top terminal block. That is, when the top heating means 11, that is, the pot lid 1 is not covered, the NTC is not connected, and the data acquisition circuit considers that the top heating means 11 is not connected at this time, the L/N line control switch is turned off. When the top heating means 11, i.e. the lid 1, is not covered, i.e. the NTC is connected, the data acquisition circuit will acquire data, which is considered to be connected to the top heating means. When the cooking function needs to be operated, the L/N line control switch is closed.
