Pressure cooking appliance with improved safety system

Abstract

The present invention provides a pressure cooking appliance with an improved safety system. The pressure cooking appliance (1) of the present invention includes: a bowl (2) and a lid (3); a device (4) for locking the lid (3) relative to the bowl (2) and is installed to movement between a locked position and an unlocked position; and a device (7) for controlling the movement of the locking / unlocking device (4) and mounted for movement between an open position and a closed position. The invention is characterized in that the appliance includes a blocking device (18) mounted movable between a position blocking the locking / unlocking device (4) and a position releasing the locking / unlocking device (4) . In addition, the blocking device (18) cooperates with the above-mentioned control device (7), so that when the control device (7) moves from the closed position to the open position, the blocking device (18) moves from the blocking position to the release position. .

Description

technical field [0001] The present invention relates to the general technical field of appliances for cooking food, and more particularly to domestic cooking appliances designed to form a substantially airtight cooking enclosure for cooking food under steam pressure. [0002] The invention more particularly relates to a domestic cooking appliance for cooking food under pressure, the appliance comprising: [0003] a cuve and a lid designed to fit and lock onto said cuve so as to form a substantially airtight cooking enclosure; [0004] locking / unlocking means for locking the lid relative to the bowl and mounted for movement on the lid between a locked position and an unlocked position; and [0005] control means for moving said locking / unlocking means, said control means being mounted in at least one open position corresponding to said unlocked position of said locking / unlocking means and in relation to said locking / unlocking means The unlocking device moves between at least ...

AI Technical Summary

Problems solved by technology

Such unlocking may then cause a sudden release of the cover, which may cause all adverse consequences

[0012] However, with most known pressure cookers provided with various overpressure safety devices, such an event is generally impossible

[0013] However, there are still difficulties in the use of the above-mentioned control mechanism, which is otherwise extremely advantageous, and in particular, it is not suitable for appliances that are subject to large deformations during normal operation, such as pressure cookers with internally mounted lids

[0014] Finally, the above-mentioned control mechanism implemented as a rotating middle part sometimes requires the user to apply very high manual force to unlock the appliance
