Embodiment Construction

[0030] figure 1 The housing of a refrigerator is shown with a body 1 and a door 2 hinged to the body, the door being shown in a partially open position. The pressure compensating valve 5 is provided in the lower corner of the door 2 and extends between the front side and the rear side of the door 2 .

[0031] figure 2 The same housing is shown with the door in a wider open position, wherein the rear side of the door towards the interior 4 of the appliance can be seen. On the rear side there is provided a magnetic seal 26, in the form of a frame, tightly against the frame 3 of the body 1 when the door 2 is closed.

[0032] In order to provide support for the magnetic seal 26, the frame 3 may be formed from a ferromagnetic sheet: for example, the case is contemplated where the foam side of the frame 3 formed of plastic is lined with a strip 27 of ferromagnetic metal, which the shape of the figure 2 The dotted outline in is shown. At the lower corners of the frame 3 , the ...

Abstract

A refrigerator has a body (1) and a door (2) which is attached to the body (1) and bounds a thermally insulated interior space (4). A pressure-compensation valve (5) permits an inflow of air from the outside into the interior space (4) and blocks an outflow of air out of the interior space (4). A front frame (3) of the body (1), which frame faces the door (2), is provided with a frame heater (27,30), and the pressure-compensation valve (1) is in thermal contact with the frame heater (27, 30), and this permits the frame heater (27, 30) to heat the pressure-compensation valve (5) to above the freezing point of water.

Description

technical field [0001] The invention relates to a refrigerator, such as a domestic refrigerator or refrigerator, having a pressure compensating valve for preventing negative pressure from being generated in the interior of the refrigerator. Background technique [0002] Every time the door of the refrigerator is opened, warm air enters the inner space of the refrigerator and cools in the inner space after the door is closed, and creates a negative pressure by which the door resists the body The front side is sucked. After the door has been closed, this negative pressure makes it difficult to open the door again until the pressure between the interior space and the environment is rebalanced. In fact, pressure compensation is always restored after an extended period of time because the seals normally fitted between the door of the refrigerator and the front side of the body do not provide a complete airtight seal, requiring generally The leakage rate of the seal is kept as l...
