Problems solved by technology

[0010] Although known air discharge devices are generally satisfactorily arranged, they still suffer from certain drawbacks
[0011] First, the operation of the air discharge mechanism needs to be carefully set so that the casing neither closes too quickly while the casing still contains air, nor closes too late to avoid pointlessly keeping the casing Temperature and pressure rises in the body or slowing leak flows require particularly precisely calibrated components that are manufactured and assembled together, complicating the manufacturing process and increasing the cost of the appliance
[0012] In addition, exposure of the discharge mechanism to particularly severe conditions can cause said mechanism to fail, for example by becoming clogged, fouled, or corroded, with the result of such failure reducing the performance of the appliance and indeed significantly shortening the its lifespan

Embodiment Construction

[0028] The invention relates to an appliance 1 of the pressure cooker type for cooking food under pressure, designed to cook food in a medium consisting of steam maintained at a pressure and temperature higher than the ambient atmospheric pressure and temperature.

[0029] According to the invention, the cooking appliance 1 comprises a container (not shown) and a lid 2 designed to be fastened on said container so as to define a casing 3 which is substantially airtight and intended to contain food.

[0030] For this purpose, said cover 2 may be provided with locking means of the type of clips, pliers, bayonets, etc. or any other equivalent system known to those skilled in the art.

[0031] The lid 2 may also be provided with one or more peripheral sealing gaskets for enabling it to fit in a tight manner on the container.

[0032] The cooking appliance 1 according to the invention may also comprise one or more regulators and safety systems for keeping the pressure prevailing ins...

Abstract

The present invention relates to an apparatus (1) for cooking food under pressure. The apparatus has a discharging device (4) capable of expelling air from a housing of the apparatus when the cooking is started, and a control device (10) that is designed to make the discharging device (4) change the structure from opening to closing. The apparatus is characterized in that the control device (10) comprises a solid actuator component (11) that is contained in a basic airtight restricting zone (12), and the restricting zone is suitable for separating the actuator component (11) from an air current (F) incoming from the housing (3).

Description

technical field [0001] The present invention relates to the general field of appliances for cooking under pressure, more particularly to domestic cooking appliances of the pressure cooker type. [0002] More particularly, the present invention relates to a cooking appliance for cooking food under pressure, the appliance comprising a container and a lid arranged to be fastened to said container to define a substantially closed enclosure for containing food. housing, the appliance is provided with: [0003] - discharge means capable of allowing air to escape from the housing at the start of cooking, said discharge means comprising: a leak opening connecting the inside of the housing with the outside of the appliance; and a closure member in contact with The leaks cooperate to enable the discharge means to alternate between an open configuration and a closed configuration in which they provide communication between the interior of the housing and the exterior of the appliance ,...
