Pressure-cooking device with improved construction and corresponding manufacturing method

Abstract

The present invention relates to a pressure-cooking device with improved structure and corresponding manufacturing method. A pressure-cooking device with installation lid inside includes at least: bowl-shaped member and lid, the lid is designed to be installed in the bowl-shaped member and to move between a closing position and an opening position; a control device (5), for making the lid move between the closing position and the opening position; an opening safety device (9), being designed to prevent the control device (5) from reaching a second position when the pressure of a container is larger than a prescribed value; the pressure-cooking device is characterized in that the control device (5) and the opening safety device (9) are all combined in a absolute mechanical subassembly (10), which is installed and fixed in said lid.

Description

technical field [0001] The present invention relates to the general technical field of food cooking appliances, in particular of the household type, designed to form an airtight cooking vessel in which food is cooked under steam pressure. [0002] The present invention more particularly relates to a pressure cooker with an internally mounted lid comprising at least: [0003] - a bowl and a cover designed to be mounted in said bowl movable at least between a closed position and an open position in which said cover cooperates with said bowl to form a substantially sealed cooking vessel, and in said open position, the interior of said vessel can be communicated with the exterior; [0004] - control means for moving said lid between its closed position and its open position, mounted at least in a first position corresponding to the closed position of said lid and to the opening of said lid moving between a second location corresponding to the location; and [0005] - An opening...

AI Technical Summary

Problems solved by technology

The purpose of this industrial method is to make the utensils have their distinguishing characteristics at the end of the process within an acceptable period of time that does not prolong the lead time of the shipment, but due to the above-mentioned design and construction, it is difficult or even impossible to carry out the method under the acceptable industrial conditions of known pressure cookers

[0034] Finally, in prior art cooking appliances with flexible lids, the relative positioning and correct fit of the safety pin and the rod depend inter alia on the manufacturing tolerances of the lid, which are often difficult to control due to the heavy metal forming techniques employed

[0035] This means that complicated and expensive industrial means must be employed in order to ensure that the safety bolt and the rod are properly mated on all lids

[0036] For the same reason, during after-sales service, the replacement of specific components mounted on the cover would be complicated to implement, since the interchangeability of the components would be compromised due to the manufacturing tolerances of the cover

In particular, replacement of the safety bolt on such known appliances requires very careful installation in order to be sure that the opening safety function is sufficiently ensured, which is very difficult to achieve
