Abstract
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 P, 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 Pis reached. Rather than being sustained until the predetermined pressure Pis reached, the open position is sustained for one of a predetermined time interval Δt after Pis reached, and until a predetermined temperature value Tis reached. The appliance is provided with at least one closure/opening safety means whose position is sensitive to pressure.
