the exhaust valve is provided with an electromagnetic coil, the opening and the closing of the exhaust valve are correspondingly controlled by electrifying and deenergizing the electromagnetic coil, and correspondingly, the control instruction is specifically used for controlling the electrification or the deenergization of the electromagnetic coil in the exhaust valve.
6. The method of claim 5, wherein the generating of the control command by the main control unit according to the current humidity and the working state of the electric pressure cooker comprises:
when the electric pressure cooker is in a water boiling state and the pressure in the electric pressure cooker reaches a preset pressure value, generating a corresponding control instruction according to a humidity interval in which the current indoor humidity value is located; or
When the electric pressure cooker is in a food rolling heating section in a food heating state, and the pressure in the electric pressure cooker reaches a preset pressure value, a corresponding control instruction is generated according to a humidity interval in which the indoor current humidity value is located.
7. The method according to claim 6, wherein the generating, by the main control unit, the corresponding control command according to the humidity interval in which the current indoor humidity value is located specifically includes:
when the indoor current humidity value is not less than a preset standard comfortable humidity value, the main control unit generates a first control instruction; wherein the first control command is for closing an exhaust valve;
when the indoor current humidity value is smaller than a preset standard comfortable humidity value and the difference value between the preset standard comfortable humidity value and the indoor current humidity value is in a first interval, the main control unit generates a second control instruction; the second control instruction is used for controlling the exhaust valve to be opened and maintaining the opening state in a first time period;
when the indoor current humidity value is smaller than the preset standard comfortable humidity value and the difference value between the preset standard comfortable humidity value and the indoor current humidity value is in a second interval, the main control unit generates a third control instruction; the third control instruction is used for controlling the exhaust valve to be opened and maintaining the opening state in a second time period;
when the indoor current humidity value is smaller than a preset standard comfortable humidity value and the difference value between the preset standard comfortable humidity value and the indoor current humidity value is in a third interval, the main control unit generates a fourth control instruction; the fourth control instruction is used for controlling the exhaust valve to be opened and maintaining the opening state in a third time period;
wherein the length of the first time period is less than the second time period, and the length of the second time period is less than the third time period.
8. The method of claim 5, wherein prior to the humidity sensor detecting the current humidity within the chamber, the method further comprises:
and controlling the humidity sensor to be turned on or off.
