A household appliance for cooking under pressure, the appliance being provided with bistable calibrated leakage means suitable for taking up an open position in which the pressure inside the appliance is allowed to increase continuously to above a determined pressure P0, while also allowing air to be bled from the appliance, and a closed position corresponding to an absence of leakage of air to the outside, the open position being sustained until a predetermined pressure value P1 is reached. Rather than being sustained until the predetermined pressure P1 is reached, the open position is sustained for one of a predetermined time interval Deltat after P0 is reached, and until a predetermined temperature value T1 is reached. The appliance is provided with at least one closure/opening safety means whose position is sensitive to pressure.
