Sealing cushion of refrigerator door

Abstract

This invention discloses a gasket for fridge door. It is arranged at the inner face edge of fridge door and firmly attached to the edge of fridge door inner face and opening face of storage chamber. It includes: expanding plate protrudes from the lateral face of the gasket; ribs which are on the expanding plate and protrude towards the inner face direction of storage chamber. The expanding plate and ribs are formed together with the gasket. It avoids cold air flowing to the connecting part of fridge door on the storage chamber opening face and storage chamber anterior edge. The gasket seals the storage chamber. The ribs undertake double sealing, which makes sealing thoroughly. This invention also avoids cold air or food entering the space between gasket and projection or fridge inner face. It avoids pollution and capacity reduction.

Description

technical field [0001] The invention relates to a refrigerator, in particular to a refrigerator door sealing gasket formed on each storage room of the refrigerator. Background technique [0002] Generally, a refrigerator is equipped with a plurality of storage rooms such as a freezer for freezing food or beverages and a refrigerator for storing food or beverages in a low-temperature environment. [0003] One side of the storage room forms an open side, and the user can store or take out the stored food. [0004] Said open face is generally opened / closed by a box door covering this open face. [0005] The door of the refrigerator and the storage room are generally made of metal or resin materials. According to the material characteristics of the door and the storage room, the junction of the door of the refrigerator and the opening of the storage room can be close to each other. [0006] A small gap is formed at the junction between the door and the opening, or it bulges du...

Problems solved by technology

[0011] But, in the sealing mode of the open face of above-mentioned prior art gasket and box door, one side of gasket is installed on the inside surface of box door and forms sealing, and the other side of gasket passes through when closing box door and open surface. Edges are joined to form a seal, and a small gap is created at the part where the gasket and the edge of the open surface are joined, and there is a problem that the cold air inside the storage room leaks to the outside through this gap.

[0012] Although the above-mentioned prior art has developed auxiliary components such as magnets used to assist in increasing the mutual joint force between the gasket and the edge of the open surface, there are still aging of the gasket and the rubber material gasket under the action of the joint force between the door and the open surface. Deformation and other phenomena occur, resulting in the defect that the open surface cannot be completely bonded

[0013] In addition, the gasket will be cooled by the cold air in the storage room, and the cooled gasket will cool the moisture in the air after the cooled gasket is joined with the air outside the refrigerator, thereby forming water droplets on the door and baffle and the outer surface of the gasket. While the water drops reduce the appearance of the refrigerator, it also increases the labor of the user to clean the water drops
