Problems solved by technology

[0016] Furthermore, when the means of fastening the metal connection part to the cover involves the aid of a previous perforation of the cover, it is then necessary to re-establish the seal of the cover where said perforation occurred, which may in some cases be complicated and expensive , with a risk of loss of reliability, especially in the long run or in cases of extreme stress (excessive stress, ...)
[0017] Certain fastening models also pose a risk of unwanted disassembly, which in the worst case can be followed by incorrect reassembly, possibly exposing the user to danger

Embodiment Construction

[0044] The invention relates firstly to a lid assembly 1 for being associated with a vessel 2 of an appliance 3 for cooking food under pressure to cooperate with said vessel 2 to form a closure for cooking under pressure. The invention also relates to an appliance 3 for cooking under pressure comprising such a lid assembly 1 . The appliance 3 for cooking under pressure is used for cooking a variety of foods in the presence of steam (eg water vapour) at a pressure level above atmospheric pressure. The steam is generated by heating a cooking liquid in the appliance 3 in the presence of food, which liquid may for example be an aqueous liquid. The appliance 3 of the invention is preferably intended for domestic use, however, it should be understood that the invention may also be applied to professional or semi-professional appliances.

[0045] The appliance 3 according to the invention is designed to raise the pressure exclusively under the action of a heat source (internal or ex...

Abstract

A cover assembly (1) comprising a plurality of parts including: - a cover (4) having an inner face (4A) and an opposite outer face (4B); and - a plurality of connecting elements (6, 7, 8, 9, 10) attached to said cover (4) to protrude from said outer face (4B); The subassembly is characterized in that each of the connecting elements (6, 7, 8, 9, 10) is attached to the cover (4) by a respective laser weld bead (11, 12). The invention also provides an appliance for cooking food under pressure.

Description

technical field [0001] The present invention relates to the technical field of appliances for cooking food under pressure in general, and in particular to cooking enclosures designed to form pressure rises capable of cooking food contained therein under water vapor pressure of the pressure cooker category of household appliances. [0002] The present invention more particularly relates to a lid subassembly for use in association with a vessel for cooking food under pressure to cooperate with the vessel to form a pressure cooking enclosure, said lid subassembly comprising a plurality of components, The plurality of components includes at least: [0003] - a metal cap having an inner face for facing the interior of the closure and an opposite outer face; and [0004] - a plurality of metal connection elements permanently and inseparably attached to the cover to protrude from the outside to mechanically connect the cover with other parts of the cover assembly. [0005] The inv...
