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

Embodiment Construction

[0045] The present invention relates to a safety valve 1 for steam pressure cooking appliances, ie appliances designed to cook food with steam by heating a cooking fluid, for example an aqueous liquid, inside the appliance and with the food produce. In known manner, the steam pressure cooking device comprises a container (with picture not shown) and a lid 2 designed to fit over the container in a substantially airtight manner to form a culinary enclosure capable of increasing pressure when the container is subjected to a heat source (which may be integrated or external) until weighed A predetermined pressure level for the "operating pressure", which is maintained by means of a regulating valve equipped with the equipment. This steam pressure cooking device is provided with an orifice 3 allowing the inside of the device to communicate with its outside. In other words, said aperture 3 communicates the inside of the culinary enclosure formed by the container and lid 2 with the ...

Abstract

The valve (1) has a flexible body including an opening (5), and a closing element (6) embedded in the body for occupying a closing position of the opening. The body is designed to leave from a sealing position so as to allow escape of steam through an orifice of a cooking appliance when pressure in the appliance reaches a safety level. A retaining unit (8) is formed of a part of the body, and prevents separation of the appliance and the body once the body is left from the sealing position.

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...
