Abstract

Official abstract text for this publication.

A refrigerator according to an embodiment of the present invention may include: a basket assembly slidably coupled to a first door in a front-to-rear direction of the first door, wherein the basket assembly comprises: a basket configured to accommodate food; a first base provided to be slidable in the front direction of the first door by passing through the opening of the first door, the basket being placed on an upper surface of the first base; a second base provided to be slidable in the rear direction of the first door, the first base being slidably coupled to an upper surface of the second base; and a third base of which a front end is fixed to a rear surface of the first door, wherein the second base is slidably coupled to an upper surface of the third base.

First claim

Opening claim text (preview).

The invention claimed is: 1. A refrigerator, comprising: a cabinet configured to form a storage space; a first door coupled to a front surface of the cabinet to selectively open and close the storage space, and having an opening formed therein; a second door coupled to a front surface of the first door and configured to selectively open and close the opening of the first door; a first hinge configured to rotatably couple the first door to the cabinet; a second hinge configured to rotatably couple the second door to the first door; and a basket assembly slidably coupled to the first door in a front-to-rear direction of the first door, wherein the basket assembly comprises: a basket configured to accommodate food; a first base provided to be slidable in the front direction of the first door by passing through the opening of the first door, the basket being placed on an upper surface of the first base; a second base provided to be slidable in the rear direction of the first door, the first base being slidably coupled to an upper surface of the second base; and a third base of which a front end is fixed to a rear surface of the first door, wherein the second base is slidably coupled to an upper surface of the third base. 2. The refrigerator of claim 1 , further comprising a case provided at the rear surface of the first door and configured to form an accommodation space in which the basket is accommodated, wherein the case has a drawing out hole which enables the basket to be drawn out of the accommodation space and to be drawn out toward the rear of the first door. 3. The refrigerator of claim 2 , further comprising a rear cover coupled to an end of the second base and configured to selectively open and close the drawing out hole, wherein, while the basket is accommodated in the accommodation space, an outer surface of the rear cover is on the same plane as a rear surface of the case. 4. The refrigerator of claim 2 , further comprising a first rail assembly configured to connect a lower surface of the first base with an upper surface of the second base, wherein, due to the first rail assembly, a front surface of the first base is able to pass through the opening and to be slid forward from a front surface of the first door by a predetermined distance. 5. The refrigerator of claim 4 , wherein the first rail assembly comprises a first rail part installed at one of the lower surface of the first base and the upper surface of the second base, and a first rail guide installed at the other one of the lower surface of the first base and the upper surface of the second base. 6. The refrigerator of claim 5 , further comprising a stopper member configured to establish a forward drawing out limit of the first base. 7. The refrigerator of claim 6 , wherein the stopper member comprises a stopping protrusion configured to protrude from an edge of at least one side surface of the opening toward a center of the opening, and a stopping groove configured to extend from an edge of at least one side surface of the first base by a predetermined length in a forward and backward direction and to accommodate the stopping protrusion. 8. The refrigerator of claim 6 , wherein the stopper member comprises a stopping protrusion configured to protrude from one of the lower surface of the first base and the upper surface of the second base, and a stopping groove configured to extend from the other one of the lower surface of the first base and the upper surface of the second base by a predetermined length in a forward and backward direction and to accommodate the stopping protrusion. 9. The refrigerator of claim 6 , wherein the stopper member comprises a stopping protrusion configured to protrude from each of the first rail part and the first rail guide and to interfere with each other. 10. The refrigerator of claim 6 , wherein the stopper member comprises a stopping protrusion configured to protrude from one of the first rail part and the first rail guide, and a stopping groove configured to extend from the other one of the first rail part and the first rail guide by a predetermined length and to accommodate the stopping protrusion. 11. The refrigerator of claim 4 , further comprising a second rail assembly configured to connect a lower surface of the second base with an upper surface of the third base, wherein, due to the second rail assembly, a rear end of the second base is able to be drawn out of the accommodation space and to be slid backward from a rear surface of the case by a predetermined distance. 12. The refrigerator of claim 11 , wherein the second rail assembly comprises a second rail part installed at one of the lower surface of the second base and the upper surface of the third base, and a second rail guide installed at the other one of the lower surface of the second base and the upper surface of the third base. 13. The refrigerator of claim 12 , further comprising a stopper member configured to establish a backward drawing out limit of the second base. 14. The refrigerator of claim 13 , wherein the stopper member comprises a stopping protrusion configured to protrude from one of the lower surface of the second base and the upper surface of the third base, and a stopping groove configured to extend from the other one of the lower surface of the second base and the upper surface of the third base by a predetermined length in a forward and backward direction and to accommodate the stopping protrusion. 15. The refrigerator of claim 13 , wherein the stopper member comprises a stopping protrusion configured to protrude from each of the second rail part and the second rail guide and to interfere with each other. 16. The refrigerator of claim 13 , wherein the stopper member comprises a stopping protrusion configured to protrude from one of the second rail part and the second rail guide, and a stopping groove configured to extend from the other one of the second rail part and the second rail guide by a predetermined length and to accommodate the stopping protrusion.
