Abstract

A refrigerator may include a cabinet disposed at a storage compartment, a door hinged to the cabinet and configured to open and close at least a portion of the storage compartment, the door including an outer door defining a front appearance of the door, a door dike defining a rear appearance of the door, and an inner space located between the outer door and the door dike, a moving frame configured to move vertically with respect to the door dike, the moving frame including a supporter configured to extend from the door dike to the inner space, and a rail embedded in the inner space configured to support the supporter.

First claim

What is claimed is:

1. A refrigerator comprising:
a cabinet disposed at a storage compartment;
a door hinged to the cabinet and configured to open and close at least a portion of the storage compartment, the door including an outer door defining a front appearance of the door, a door dike defining a rear appearance of the door, and an inner space located between the outer door and the door dike, the inner space being configured to be filled with a filler for insulation;
a loop-shaped moving frame that is coupled to a lower part of a basket, and that is configured to move vertically with respect to the door dike, the moving frame including a supporter configured to extend from the door dike to the inner space and an extending frame that is configured to extend perpendicular to the loop-shaped moving frame, wherein the supporter includes a supporter frame that is coupled to the extending frame; and
a rail embedded in the inner space configured to support the supporter;
a cut-shaped rail mount unit formed at the door dike and configured to be coupled to the rail at the inner space of the door;
a rail coupling opening formed at the door dike and defining a rail coupling space that is located inside the door dike, one end of the rail being disposed at the rail coupling space and the supporter being inserted into the rail coupling space from outside of the door dike through the rail coupling opening to be coupled to the rail; and
a coupling cover configured to cover the rail coupling opening and the rail coupling space from outside of the door dike after the supporter is coupled to the rail.

2. The refrigerator according to claim 1 , wherein the rail and the rail mount unit are covered by a rail cover bracket disposed at the inner space.

3. The refrigerator according to claim 2 , wherein the rail cover bracket is coupled to the rail, wider than the rail and the cut-shaped rail mount unit and completely covers the rail and the cut-shaped rail mount unit.

4. The refrigerator according to claim 3 , wherein, when the inner space is filled with a filler, the rail cover bracket is disposed to separate the inner space into a first space for the filler and a second space for accommodating the rail and the cut-shaped rail mount unit.

5. The refrigerator according to claim 4 , wherein the rail cover bracket includes a lattice rib at an outer surface of the rail cover bracket to increase a coupling area between the rail cover bracket and the filler.

6. The refrigerator according to claim 1 , wherein the loop-shaped moving frame is configured to have a square closed loop by aluminum die-casting.

7. The refrigerator according to claim 1 , further comprising a moving basket comprising the moving frame and the basket that is configured to accommodate goods and that is coupled to the moving frame, wherein the loop-shaped moving frame and the basket are configured to move in an integrated manner.

8. The refrigerator according to claim 7 , wherein the supporter frame includes a plurality of rollers at upper and lower parts of the supporter.

9. The refrigerator according to claim 8 , wherein the basket is seated at an upper part of the loop-shaped moving frame and the loop-shaped moving frame is configured to be inserted into a lower part of the basket such that the moving frame supports load applied to the basket.

10. The refrigerator according to claim 9 , wherein the basket includes insertion grooves which are configured to receive the extending frame.

11. The refrigerator according to claim 10 , wherein the insertion grooves are located at both left and right sides of the basket.

12. The refrigerator according to claim 1 , wherein the supporter comprises rollers disposed at upper and lower sides of the supporter, and wherein the rail comprises a roller guide configured to move the rollers vertically.

13. The refrigerator according to claim 12 , wherein the roller guide includes a plurality of roller openings spaced a distance away from one another at one side of the roller guide.

14. The refrigerator according to claim 13 , wherein outer parts of the rollers include an elastic material, and
wherein the rollers are configured to elastically deform based on the rollers moving along the roller guide, and elastically restore at the roller openings to be partially inserted into the roller openings.

15. The refrigerator according to claim 14 , wherein the supporter comprises a lever that is configured to be selectively inserted into the roller openings to limit the vertical movement of the loop-shaped moving frame.

16. The refrigerator according to claim 15 , wherein the supporter comprises an operation unit that is configured to adjust displacement of the lever based on an input displacement provided by a user.

17. The refrigerator according to claim 16 , further comprising a spring disposed between the operation unit and the lever, the spring being configured to return the operation unit and the lever to an original position.

18. The refrigerator according to claim 17 , wherein the operation unit, the lever, and the spring are accommodated in a supporter cover.
