Problems solved by technology

The partial vacuum that exists in the interior space of the refrigerator is detrimental as it makes it more difficult to open the door
The actual opening operation of the door is delayed because the user has to move the handle 13 over a certain distance for operating the lifting elements 14, 15 and the pressure equalization between the environment and the interior space of the refrigerator takes a certain time

Embodiment Construction

[0030] Figure 1 shows in a highly schematic manner a refrigerator with a body 1 and a door 2 pivoting on it; said body 1 and door 2 together delimit an interior space 3 and a magnetic seal 4; fixed to the inside perimeter of the door 2, and magnetically attached to the contact surface 5 on the front side of the body 1 in an airtight manner, so that: if warm air enters the interior space 3, the door 2 closes in an airtight manner and After the air has cooled in the interior space 3 , a partial vacuum can be eliminated in the interior space 3 .

[0031]In the heat-insulating wall 6 on the bottom of the body 1 , a lifting element 7 is arranged in a recess 8 . The lifting element 7 is made of a temperature-dependent deformable material such as a shape memory alloy or bimetal. Below the lifting element 7 , a heating device 10 , here a PTC heating device 10 , which serves to heat the lifting element 7 , is arranged in the recess 8 .

Abstract

The invention relates to a method for operating a refrigerator comprising two movably connected housing parts, a frame (1) and a door (2) which jointly delimit a heat-insulated interior (3), as well as a seal (4) that is fastened to a first of the housing parts (2) and airtightly contacts the other, second housing part (1) in the closed position of both housing parts. The inventive method encompasses a step (a) in which the airtight contact between the seal (4) and the second housing part (1) is prevented for a specific period of time along a section of the seal while the sealing contact between the seal (4) and the second housing part (1) is subsequently restored along said section of the seal in a step (b). The invention also relates to a refrigerator for carrying out said method.

Description

technical field [0001] The present invention relates to refrigerators and methods of operation thereof. The refrigerator has a body and a door as two movably connected housing parts jointly defining an insulated interior space, and a seal fastened to a first of the two housing parts and The two housing parts are in gas-tight contact with the other second housing part in the closed position. In order to achieve an air pressure balance between the external atmosphere surrounding the refrigerator and the interior space of the refrigerator, in step (a) of the method, at the closed position of the two housing parts along a portion of the length of the seal, the seal is prevented for a period of time Gas-tight contact between the part and the second housing part. The invention also relates to a refrigerator implementing said method. The refrigerator includes a lifting element that makes air-tight contact between the seal and the second housing part in a first position, and can be...
