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; 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.

2 . The refrigerator according to claim 1 , wherein the door dike includes a cut-shaped rail mount unit, and wherein the rail is coupled to the rail mount unit at the inner space.

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

4 . The refrigerator according to claim 3 , wherein the rail cover bracket is coupled to the rail, wider than the rail and the rail coupling unit, and completely covers the rail and the rail coupling unit.

5 . The refrigerator according to claim 4 , 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 rail coupling unit.

6 . The refrigerator according to claim 5 , 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.

7 . The refrigerator according to claim 2 , wherein the door dike includes a rail coupling opening through which the supporter is configured to move forward and rearward along the rail to be coupled to the rail.

8 . The refrigerator according to claim 7 , wherein the rail coupling opening is covered by a coupling cover after the supporter is coupled to the rail.

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

10 . The refrigerator according to claim 1 , wherein the moving basket comprises a basket that is configured to accommodate goods coupled to the moving frame, and wherein the moving frame and the basket are configured to move in an integrated manner.

11 . The refrigerator according to claim 10 , wherein the supporter comprises a supporter frame including a plurality of rollers at upper and lower parts of the supporter, and wherein the moving frame comprises an extending frame coupled to the supporter frame.

12 . The refrigerator according to claim 11 , wherein the basket is seated at an upper part of the moving frame and the 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.

13 . The refrigerator according to claim 12 , wherein the basket includes insertion grooves which are configured to receive the extending frame.

14 . The refrigerator according to claim 13 , wherein the insertion grooves are located at both left and right sides of the basket.

15 . 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.

16 . The refrigerator according to claim 15 , wherein the roller guide includes a plurality of roller openings spaced a distance away from one another at one side of the roller guide.

17 . The refrigerator according to claim 16 , wherein the 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.

18 . The refrigerator according to claim 17 , wherein the supporter comprises a lever that is configured to be selectively inserted into the roller openings to limit the vertical movement of the moving frame.

19 . The refrigerator according to claim 18 , wherein the supporter comprises an operation unit that is configured to adjust displacement of the lever based on the user's input displacement.

20 . The refrigerator according to claim 19 , 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.

21 . The refrigerator according to claim 20 , wherein an interlocking part is located between the operation unit and the lever, and wherein the interlocking part, the operation unit, the lever, and the spring are accommodated in a supporter cover.
