Safety valve for pressure-cooking appliance and device including such a valve

Abstract

The invention relates to a safety valve (1) for a pressure-cooking appliance having an orifice (3) communicating the interior of the appliance with the outside, said valve (1) comprising a flexible body (4) having an aperture (5) passing through the flexible body (4), and a shutter (6) embedded in the flexible body to occupy a closed position, said flexible body being adapted to be mounted on the appliance so as to occupy a sealing position in which the valve (1) closes said orifice (3), said shutter ( 6) being adapted to leave the closed position so as to allow a leakage of steam through said aperture (5) when the pressure in the appliance reaches a first level of security. The safety valve is characterized in that said soft body is adapted to leave the sealing position so as to allow a leakage of steam when the pressure in the appliance reaches a second level of security, said valve (1) comprising a first holding member (8) being a part of the flexible body and adapted to prevent the separation of the appliance and the flexible body.

Description

technical field [0001] The present invention relates to the general technical field of household pressure cooking apparatus comprising a container and a lid designed to lock onto the container to form a substantially airtight cooking enclosure, such apparatus being designed such that the food contained in the container is cooked under steam pressure Next cook. [0002] The invention relates more particularly to a safety valve for a pressure cooking appliance provided with an orifice allowing the inside of the appliance to communicate with its outside, said valve firstly comprising a flexible body through which an opening passes, said valve secondly comprising a joint Within the flexible body with a closure member occupying at least a closed position in which the valve closes the opening, the flexible body is designed to be mounted on the device in a manner occupying at least a sealing position in which, A valve closes the orifice, the closing member being designed to leave it...

AI Technical Summary

Problems solved by technology

Such devices employing fusible material pose a food safety hazard (residues of the fusible material can fall into and mix with food without the user being able to detect it) and are irreversible, prevent the user from easily reusing the device, and make the user Must use after-sales service

[0013] This irreversible problem is also encountered in appliances that create leaks by applying deformation of the metal parts of the pressure cooker (container, lid and locking mechanism) through a safety device of last resort

This deformation usually occurs in the field of plastics, so that the pressure cooker is then irreparably deformed and thus unusable

[0014] Spring-loaded safety valves are relatively complex and expensive to manufacture, do not have good precision, and are not easy to clean, while pop-up finger valves have the drawback of ejecting metal fingers in the event of overpressure, which can injure the user and / or be lost
