Embodiment Construction

[0033] exist figure 1 The refrigerating device shown in the schematic diagram of has a generally cuboid body 1 and a door 2 attached thereto. The stringers 3 joined together to form a rectangle are formed by deep drawing on a rectangular thermoplastic sheet 12 , wherein the thermoplastic sheet 12 serves here as an inner cladding and forms the largest part of the inner side of the door 2 . In the closed position of the door 2 the stringers 3 engage with the body 1 . The stringers 3 are enclosed by a continuous edge strip 6 as a first frame surface 6 . The magnetic seal 4 is in the closed position substantially airtight with respect to and rests against the front second frame surface 5 of the body, while the magnetic seal 4 is anchored on the inside of the door in a manner well known to those skilled in the art. In a groove extending between the stringer 3 and the edge strip 6 .

[0034] exist figure 1 In the completed assembled condition of the magnetic seal 4, only the fla...

Abstract

A body (1) and a door (2) of a refrigeration device surround a cooled interior space and have frame surfaces (5; 3, 6) which face one another and bound a gap which is filled by a seal (4). A passage (8, 9, 18) which bridges the seal (4) is formed in at least a first of the frame surfaces (6). A non-return valve (17) is provided at the passage (8, 9, 18).

Description

technical field [0001] The present invention relates to a refrigeration device, in particular a domestic refrigeration device, such as a refrigerator or freezer, with a pressure compensating opening, the purpose of which is to prevent the formation of a vacuum inside the refrigeration device. Background technique [0002] Every time the door of the refrigerator is opened, warm air reaches inside the refrigerator and after the door is closed the air cools down and creates a vacuum so that the door is vacuumed against the front side of the appliance body. The result of this vacuum is that it is very difficult to open the door again after it has been closed long enough, until the pressure between the interior and the environment is rebalanced. In fact, pressure compensation has always been reoccurring after a long time, because the seals usually fitted between the door and the front side of the refrigeration unit body do not provide a completely airtight seal, and the leakage r...
