Abstract

A refrigerator includes a cabinet defining a storage compartment, a door, a drawer, a roller at a side of the drawer, and a withdrawal frame in the storage compartment configured to support the drawer and move in a forward-rearward direction, and a link rotatably that is connected to the door and a connection shaft, that is configured to move the withdrawal frame forward based on the door being opened and to move the withdrawal frame rearward based on the door being closed, and that defines, along a longitudinal direction of the link, a connection hole that is configured to receive the connection shaft, the link being located at the withdrawal frame.

First claim

What is claimed is:

1. A refrigerator comprising:
a cabinet that defines a storage compartment with an opening;
a door rotatably coupled to the cabinet and configured to open and close the opening;
a drawer located in the storage compartment and configured to store food;
a roller located at a side of the drawer;
a withdrawal frame that is located in the storage compartment, that is configured to support the drawer, and that is configured to move in a forward-rearward direction; and
a link that is rotatably connected to the door at a side of the link and rotatably connected to a connection shaft at an other side of the link, that is configured to move the withdrawal frame forward based on the door being opened and to move the withdrawal frame rearward based on the door being closed, and that defines, along a longitudinal direction of the link, a connection hole that is configured to receive the connection shaft, the link being located at the withdrawal frame,
wherein the withdrawal frame comprises:
a horizontal base part that includes the connection shaft;
a side part that extends upward from the horizontal base part; and
a drawer guide that is located at the side part, that is configured to support the roller, and that is configured to guide the roller in the forward-rearward direction to enable the drawer to move in the forward-rearward direction relative to the withdrawal frame based on the withdrawal frame moving relative to the storage compartment.

2. The refrigerator according to claim 1 , wherein the connection hole is configured to guide movement of the connection shaft in a direction that is perpendicular to a center axis of the connection shaft.

3. The refrigerator according to claim 2 , wherein a rear end of the connection hole that is nearer to a rear of the refrigerator than a front end of the connection hole and that is spaced apart from the connection shaft based on the door being closed.

4. The refrigerator according to claim 3 , wherein the rear end of the connection hole is configured to contact the connection shaft based on the door being opened to a predetermined withdrawal start angle defined with respect to a front surface of the refrigerator.

5. The refrigerator according to claim 4 , wherein the predetermined withdrawal angle is less than or equal to 90 degrees.

6. The refrigerator according to claim 3 , wherein the connection shaft is spaced apart from the front end of the connection hole based on the door being opened to a maximum withdrawal angle defined with respect to a front surface of the refrigerator.

7. The refrigerator according to claim 6 , wherein the maximum withdrawal angle is greater than 90 degrees.

8. The refrigerator according to claim 1 , wherein the withdrawal frame further comprises:
an additional side part that extends from the horizontal base part; and
an additional drawer guide that is located at the additional side part and that faces the drawer guide.

9. The refrigerator according to claim 1 , wherein the connection shaft protrudes downward from the horizontal base part.

10. The refrigerator according to claim 1 , further comprising a pair of frame legs that protrude from a bottom surface of the horizontal base part and that are spaced apart from each other in a lateral direction of the storage compartment, each of the pair of frame legs comprising a plurality of rollers configured to move along a bottom of the storage compartment in the forward-rearward direction.

11. The refrigerator according to claim 10 , further comprising a guide rail located at the bottom of the storage compartment and configured to guide movement of the pair of frame legs in the forward-rearward direction.

12. The refrigerator according to claim 11 , further comprising:
a vertical partition that divides the interior of the storage compartment into a left part and a right part,
wherein the vertical partition and the guide rail define a space that is configured to receive a first frame leg of the pair of frame legs.

13. The refrigerator according to claim 12 , further comprising a pair of additional guide rails that define a space that is configured to receive a second frame leg of the pair of frame legs.

14. The refrigerator according to claim 1 , further comprising:
additional drawers that located above or below the drawer, and
additional drawer guides that are located at the withdrawal frame and that are configured to guide the additional drawers.
