Problems solved by technology

If this is the case only along part of the length of the seal, there will be a seal leak at the location between the front frame and the door; in extreme cases this can cause the door to no longer close tightly
[0003] Said problem arises in particular along the horizontal extension of the seal, since there is a particularly high risk of repulsion-inducing misalignment of the magnets in this part, due to, for example, the presence of storage shelves mounted on the door. highly variable load

Embodiment Construction

[0014] figure 1 A freezer is shown having a body 1 and a door 2 fastened to the body 1 by a multi-link hinge 3 . The door has on its inside a magnetic seal 4 forming a rectangular frame, a multi-chambered hollow made of flexible plastic, in which a magnet is housed in one of the cavities. While it can be shown, for simplicity, the storage shelves installed in the doors for containing refrigerated items are not shown.

[0015] When the door is in the closed position, a magnetic seal 4 is applied against the plastic front frame 5 forming the front side of the body 1 .

[0016] figure 2 is a perspective rear view of the front frame 5 and the inner container 6 assembled on the front frame 5 by the inner container 6 assembled from a plurality of metal sheets. Arranged in the shape of a frame on the rear side of the front frame and around the opening of the inner container is a magnet 7 . The magnets described can be assembled from individual pieces. A mesh 8 bent at right ang...

Abstract

Disclosed is a refrigerator comprising a body (1) and a door (2), The body (1) is provided with a front frame (5) that is made of a low heat-conducting material such as plastic or similar and is backed by a first magnet (7). A door (2) seal (4) that is fitted with a second magnet (9) seals against the front frame (5) in the closed position of the door (2). Opposite first poles (7N, 9S) of the two poles (7N, 7S; 9N, 9S) of each magnet (7, 9) face the contact area between the seal (4) and the front frame (5) while second poles (7S; 9N) face away from the contact area.

Description

technical field [0001] The invention relates to a freezer with a housing and a door, wherein the housing has a front frame made of plastic. Front frames of the type described are used in particular in freezers in which both the inner container and the outer shell are made of metal, in order to prevent the formation of cold bridges between the inner container and the outer shell. Background technique [0002] Freezer doors typically have a flexible seal equipped with magnets that are pulled by a magnetic force when the door is closed, which acts to hold the door tightly against the front frame. If the front frame is not made of ferromagnetic sheet metal, but of plastic, the ferromagnetic material attracted by the magnets of the seal can only be attracted behind the front frame, resulting in a minimum distance between the magnet and the ferromagnetic material Will increase due to the degree of thickness of the front frame material, the attractive force will be greatly reduced...
