To normal pressure.That is, pressure relief device 50 can make instantaneous release in cooking cavity 11, instantaneous release can be such that rice is turned over
Rolling increases the being heated evenly property of rice to reduce rice agglomeration.
Specifically, it when the pressure in cooking cavity 11 is negative pressure, is pressurized.Two coils of solenoid valve 40 first
Must not be electric, potential device 30 does not work, so that cooking cavity 11 be made to be in air-tight state, pressure relief device 50 can open work,
To make the pressure in cooking cavity 11 from negative pressure variation to normal pressure；When the pressure in cooking cavity 11 is normal pressure, pressure relief device 50
It closes, then the right side coil of solenoid valve 40 obtains electric, and booster pump 3 starts to carry out air inlet to cooking cavity 11, makes in cooking cavity 11
Pressure is changed to positive pressure from normal pressure.
When the pressure in cooking cavity 11 is positive pressure, depressurized.Two coils of solenoid valve 40 first must not
Electricity, potential device 30 do not work, so that cooking cavity 11 be made to be in air-tight state, pressure relief device 50 can open work, to make
Pressure in cooking cavity 11 is changed to normal pressure from positive pressure；When the pressure in cooking cavity 11 is normal pressure, pressure relief device 50 is closed, so
The left side coil of solenoid valve 40 obtains electric afterwards, and control vacuum pump 31 vacuumizes, and is changed to the gas in cooking cavity 11 from normal pressure negative
Pressure.
Optionally, the pressure in cooking cavity 11 is from negative pressure to positive pressure, from negative pressure is just pressed onto, at least variation is primary respectively.Example
Such as, then the pressure in cooking cavity 11 can be changed to again negative pressure from positive pressure first from negative pressure variation to positive pressure；Or cooking cavity 11
Interior pressure first can be changed to negative pressure from positive pressure, then be changed to positive pressure again from negative pressure, and so on.

To normal pressure state.
After S2, cooking cavity 11 enter normal pressure, closeouts 51 block relief port 23, and 40 left side coil of solenoid valve is powered, very
31 work of sky pump makes cooking cavity 11 form negative pressure state, after air pressure reaches P2kPa, electromagnetism to be evacuated to cooking cavity 11
Valve 40 power off, cooking cavity 11 can maintain air pressure P2kPa for a period of time after, control closeouts 51 open, make in cooking cavity 11
Gas boosting is rapidly achieved normal pressure state.
At least one period of state or more of S3, circulation step S1 and S2, until entering heated condition；
In the entire water suction stage, 50 cycle operation of potential device 30, solenoid valve 40 and pressure relief device, cook when cancellation or
When person enters the heating period, potential device 30, solenoid valve 40 and pressure relief device 50 can then power off immediately to stop working.
According to an embodiment of the invention, air pressure of the cooking apparatus 100 within the water suction stage, cooking cavity 11 realizes positive/negative-pressure
Alternating variation, and then rice internal pressure changes repeatedly, and the air in the grain of rice accelerates discharge, can make the water imbibition of rice more
By force, while absorbent time shortens, and speed of cooking is accelerated；Pressure relief device 50 can allow the air pressure in cooking cavity 11 not by external force
In the case where restore normal pressure, reduce the consuming of the energy, instantaneous release also has certain rolling to act in rice, increases rice
Being heated evenly property.
