Abstract

A refrigerator includes a main body, a storage compartment provided inside the main body and having an open front side of the storage compartment, a door rotatably coupled to the main body and which opens or closes the open front side of the storage compartment, and a gasket coupled to a rear side of the door to maintain a seal between the main body and the door when the door is closed. The gasket includes a first gasket coupled to the rear side of the door to absorb an impact generated between the door and the main body when the door is closed and a second gasket provided as an integrated injection molded product and coupled to a rear side of the first gasket to maintain the seal between the door and the main body when the door is closed.

First claim

What is claimed is:

1. A refrigerator comprising:
a main body;
a storage compartment provided inside the main body and having an open front side of the storage compartment;
a door rotatably coupled to the main body to open or close the open front side of the storage compartment; and
a gasket coupled to a rear side of the door to maintain a seal between the main body and the door when the door is closed,
wherein the gasket comprises:
a first gasket coupled to the rear side of the door to absorb an impact generated between the door and the main body when the door is closed, wherein
the first gasket includes a coupling part coupled to the rear side of the door,
a shock absorbing unit configured to absorb an impact generated between the door and the main body when the door is closed, and
a plurality of coupling projections extending from the shock absorbing unit and away from the coupling part, and
a second gasket provided as an integrated injection molded product and coupled to a rear side of the first gasket to maintain the seal between the door and the main body when the door is closed, wherein:
at least a portion of the first gasket is not covered by the second gasket, and
a plurality of coupling grooves corresponding to the plurality of coupling projections are provided on an exterior surface of the second gasket so that the first gasket and the second gasket are detachably coupled.

2. The refrigerator according to claim 1 , wherein the first gasket comprises:
an upper gasket which corresponds to an upper edge of the rear side of the door;
a lower gasket which corresponds to a lower edge of the rear side of the door;
a left gasket which corresponds to a left edge of the rear side of the door; and
a right gasket which corresponds to a right edge of the rear side of the door.

3. The refrigerator according to claim 2 , wherein each of the upper gasket, the lower gasket, the left gasket, and the right gasket of the first gasket is extrusion-molded and bonded to have a square shape corresponding to the upper edge, the lower edge, the left edge, and the right edge of the rear side of the door, respectively.

4. The refrigerator according to claim 1 , wherein the second gasket is injection molded integrally with a magnet to embed the magnet inside the second gasket.

5. The refrigerator according to claim 1 , wherein the second gasket is coupled to the rear side of the first gasket to prevent exposure of a bonded trace of the first gasket to the outside.

6. The refrigerator according to claim 1 , wherein the second gasket is formed with a magnetic strength based on the distance.

7. The refrigerator according to claim 5 , wherein the second gasket is selected based on a distance between the main body and the door.

8. The refrigerator according to claim 5 , wherein the second gasket has one of a plurality of different colors.

9. The refrigerator according to claim 8 , wherein a gasket color for the second gasket is selected to match a color of the rear side of the door.

10. A refrigerator, comprising:
a main body;
a storage compartment provided inside the main body and having an open front side of the storage compartment;
a door rotatably coupled to the main body to open or close the open front side of the storage compartment; and
a gasket formed in a square shape to correspond to edges of a rear side of the door and coupled to the rear side of the door to maintain a seal between the main body and the door when the door is closed,
wherein the gasket comprises:
a first gasket coupled to the rear side of the door to absorb an impact generated between the door and the main body when the door is closed, wherein:
the first gasket includes a coupling part coupled to the rear side of the door,
a shock absorbing unit configured to absorb an impact generated between the door and the main body when the door is closed, and
a plurality of coupling projections extending from the shock absorbing unit and away from the coupling part, and
a second gasket coupled to a rear side of the first gasket to maintain a seal between the door and the main body when the door is closed, wherein:
the second gasket is divided into a plurality of corner sections arranged in corners of a square shape and a plurality of connecting sections connecting the plurality of corner sections and provided as an injection molded product, wherein
at least a portion of the first gasket is not covered by the second gasket, and
a plurality of coupling grooves corresponding to the plurality of coupling projections are provided on an exterior surface of the second gasket so that the first gasket and the second gasket are detachably coupled.

11. The refrigerator according to claim 10 , wherein the second gasket is used by replacing only the plurality of connection sections according to a size of the door.

12. A refrigerator comprising:
a main body;
a storage compartment provided inside the main body and having an open front side of the storage compartment;
a door rotatably coupled to the main body to open or close the open front side of the storage compartment; and
a gasket coupled to a rear side of the door to maintain a seal between the main body and the door when the door is closed,
wherein the gasket comprises:
a first gasket coupled to the rear side of the door to absorb an impact generated between the door and the main body when the door is closed, wherein:
the first gasket includes a coupling part coupled to the rear side of the door,
a shock absorbing unit configured to absorb an impact generated between the door and the main body when the door is closed, and
a plurality of coupling projections extending from the shock absorbing unit and away from the coupling part; and
a second gasket coupled to a rear side of the first gasket to maintain a seal between the door and the main body when the door is closed and provided as an injection molded product integrally formed with a magnet to embed the magnet inside the second gasket, wherein:
at least a portion of the first gasket is not covered by the second gasket, and
a plurality of coupling grooves corresponding to the plurality of coupling projections are provided on an exterior surface of the second gasket so that the first gasket and the second gasket are detachably coupled.

13. The refrigerator according to claim 12 , wherein the first gasket is divided into a plurality of pieces, extrusion-molded, and bonded to have a square shape corresponding to edges of the rear side of the door.
