The present invention relates to a refrigerator, and more particularly, to a sealing member of a door for a refrigerator, wherein the door and the door are joined to a door to cover an open surface formed in each storage compartment of the refrigerator.

In general, a refrigerator is provided with a plurality of storage compartments, such as a freezer compartment for freezing food or drink and a refrigerating compartment for storing the food or drink at low temperature.

In addition, the storage compartment has an open surface such that one surface thereof, such as a front surface thereof, is opened so that a user can store or take out food.

In addition, the open surface is generally formed to be opened / closed by a door formed to cover the open surface.

In addition, the refrigerator door and the storage compartment are generally made of a metal or resin material, and it is not possible to closely contact the joint portions of the door and the storage compartment opening surface according to the material properties of the door and the storage compartment.

Accordingly, since a minute gap is formed or floated at the junction between the door and the open surface, the cool air filled inside the storage compartment leaks to the outside of the refrigerator through the gap formed at the junction between the door and the open surface. There was a problem.

Therefore, the conventional refrigerator has been used to block the gap formed in the joint portion of the door and the open surface provided with a gasket formed of a resilient material in the joint portion of the door and the open surface.

Here, the gasket is made of an elastic material made of a rubber material formed to be in close contact with both the inner surface and the open surface of the door while having a predetermined thickness on a portion where the door and the open surface of the storage chamber contact each other, that is, the inner edge of the door. It was common to be.

Accordingly, when closing the door provided on the storage compartment opening surface of the refrigerator, the gasket provided on the inner edge of the door is in close contact with the edge of the opening surface.

In this case, one surface of the gasket is fastened to the inner surface of the door to form a seal, and the other surface of the gasket is in close contact with the edge of the storage compartment opening surface to close the door and the opening surface.

However, the sealing of the opening surface and the door using the conventional gasket as described above, while one surface of the gasket is fastened to the inner surface of the door to form a seal, while the other surface of the gasket is opened by the closing action of the door. As the sealing is formed by contacting the edge of the gasket, another gap may be formed at the portion where the gasket and the edge of the open surface are in contact with each other, and there is a problem in that cold air inside the storage compartment leaks through the gap. .

In addition, although the use of auxiliary binding members such as magnets to assist the bonding force between the gasket and the open surface has been developed so that the edges of the gasket and the open surface close to each other, the aging of the gasket, the door and the dog of the gasket made of the rubber material There was a problem that the complete joining of the open surface is impossible due to deformation due to the bonding strength of the side.

In addition, the gasket provided at the junction of the door and the open surface is cooled by the cold air of the storage compartment, the cooled gasket is in contact with the air outside the refrigerator to generate water droplets, as well as the appearance of the refrigerator is reduced, There was a problem to handle the water droplets.

The present invention has been invented to solve the above problems, an object of the present invention is to provide a sealing member of the door for a refrigerator to seal the joint of the door and the open surface of the refrigerator storage compartment.

Another object of the present invention is to provide a sealing member of a door for a refrigerator to improve the sealing ability of the junction portion by blocking the circulation of cold air filled in the storage compartment through the junction between the open surface of the refrigerator compartment and the door. Has its purpose.

Another object of the present invention is to provide a sealing member of a door for a refrigerator, which is to be installed together with a gasket installed on the refrigerator door.

Another object of the present invention is to provide a sealing member of a door for a refrigerator that can achieve a more rigid fixing effect according to the installation of the gasket of the refrigerator door.

The present invention for achieving the above object is that the sealing member is installed to block the cold air circulated to the joint portion of the open surface and the door on the inner edge of the door covering the open open surface of the refrigerator storage compartment. It features.

Another feature of the present invention, the sealing member is a body bonded to the outer surface of the dyke formed on the inner surface of the refrigerator door, and when the door is closed in the body protrudes in the direction of the inner surface of the storage compartment to face the dyke And a fixed ring formed at the end of the body and fixed to an inner surface of the door, and a finish formed by bending in the direction of the dyke at the tip of the body.
