Abstract

A refrigerator that is capable of enabling a user to easily introduce or remove goods into or from the refrigerator is described. Specifically, a refrigerator that is capable of enabling a drawer for receiving goods to be more conveniently used is described. The refrigerator includes a cabinet having a storage compartment with a food introduction port formed in the front thereof, a door hingedly connected to the cabinet for opening and closing the storage compartment, a plurality of drawers disposed in the storage compartment, the drawers being arranged vertically, a moving frame extending vertically so as to correspond to the height at which the drawers are disposed, the moving frame being configured to selectively push the drawers such that the drawers are moved toward the food introduction port, an electric driving unit coupled to the moving frame for moving the moving frame toward the food introduction port, and a controller for controlling the electric driving unit to move the moving frame when it is sensed that the door is open.

Claims (37)

1. A refrigerator comprising:

a cabinet with a storage compartment;

a partitioning wall that is configured to partition the storage compartment into a left compartment and a right compartment;

a drawer in the left compartment and a drawer in the right compartment;

a moving frame configured to push at least one of the drawer in the left compartment or a drawer in the right compartment while being moved forward; and

an electric driving unit comprising a motor assembly, and a connection member that is configured to interconnect the motor assembly and the moving frame,

wherein the motor assembly comprises a first motor assembly on a first position of the partitioning wall for the drawer in the left compartment and a second motor assembly on a second position of the partitioning wall for the drawer in the right compartment, and

wherein the connection member comprises an extension part that is configured to extend in a direction that reduces a twist of the moving frame caused by the moving frame pushing on at least one of the drawer in the left compartment or the drawer in the right compartment.

2. The refrigerator of claim 1 , wherein the first position and the second position are arranged side by side on the partitioning wall, and

wherein the direction to reduce the twist of the moving frame caused by the moving frame pushing on at least one of the drawer in the left compartment or a drawer in the right compartment is one of

a first direction to the first position from the second position or a second direction to the second position from the first position.

3. The refrigerator of claim 2 , wherein the first position and the second position are vertically arranged, and

wherein the extension part is configured to extend upward or downward from the end of a connected portion that is configured to interconnect the motor assembly and the moving frame respectively in a downward direction or an upward direction.

4. The refrigerator of claim 1 , wherein the drawer in the left compartment and a drawer in the right compartment comprise:

multiple drawers vertically arranged in the left compartment; and

multiple drawers vertically arranged in the right compartment.

5. The refrigerator of claim 4 , wherein the moving frame is a single moving frame configured to push the multiple drawers in the left compartment or the multiple drawers in the right compartment.

6. The refrigerator of claim 1 , wherein the moving frame is connected with at least one of the drawer in the left compartment or the drawer in the right compartment so as to apply a force to the drawer in a direction in which the at least one of drawer in the left compartment or the drawer in the right compartment is withdrawn from an initial position to a manipulating position.

7. The refrigerator of claim 6 , wherein the moving frame is disconnected from the at least one of the drawer in the left compartment or the drawer in the right compartment so as not to apply a force to the drawer in a direction in which the drawer is inserted from the manipulating position to the initial position.

8. The refrigerator of claim 6 , further comprising:

a door hingedly connected to the cabinet and that is configured to open and close the storage compartment; and

a sensor configured to sense whether the door is open.

9. The refrigerator of claim 8 , wherein the electric driving unit is configured to move the moving frame forward such that at least one of the drawer in the left compartment or the drawer in the right compartment are withdrawn forward when the sensor sensed the door is opening.

10. The refrigerator of claim 8 , further comprising:

a drawer holder that is configured to selectively connect to each of the drawer in the left compartment and the drawer in the right compartment to provide elastic restoring force to the drawer in the left compartment and the drawer in the right compartment, when the at least one of the drawer in the left compartment or the drawer in the right compartment moves back from the manipulating position to the initial position.

11. The refrigerator of claim 10 , wherein the moving frame comprises a transfer member connected to each of the drawer in the left compartment and the drawer in the right compartment at a first height, and

wherein the drawer holder is configured to selectively connect to each of the drawer in the left compartment and the drawer in the right compartment at a second height, which is different from the first height.

12. The refrigerator of claim 11 , wherein each of the drawer in the left compartment and the drawer in the right compartment comprise a first catching member on the first height and a second catching member on the second height.

13. The refrigerator of claim 12 , wherein the drawer holder further comprises a hanging member, and

wherein the selective connection between the drawer holder and each of the drawer in the left compartment and the drawer in the right compartment is through a connection between the hanging member and the second catching member of each of the drawer in the left compartment and the drawer in the right compartment.

14. The refrigerator of claim 13 , wherein the hanging member of the drawer holder is connected to the second catching member of each of the drawer in the left compartment and the drawer in the right compartment, when the opening of the door is sensed and at least one of the drawer in the left compartment and the drawer in the left compartment move from the initial position to an elastic force starting position located in advance of the initial position.

15. The refrigerator of claim 13 , further comprising:

a rail configured to support at least one of the drawer in the left compartment or the drawer in the right compartment to move forward and backward relative to the storage compartment.

16. The refrigerator of claim 15 , wherein the rail extends from the initial position to a maximum withdrawal position located in advance of the manipulating position.

17. The refrigerator of claim 16 , wherein the connection between the hanging member of the moving frame and each of the drawer in the left compartment and the drawer in the right compartment is released at an elastic force ending position located between the manipulating position and the maximum withdrawal position.

18. The refrigerator of claim 16 , wherein a housing of the drawer holder further comprises an inclined slot such that the connection between the hanging member of the drawer holder and the second catching member of at least one of the drawer in the left compartment or the drawer in the right compartment is released at an elastic force ending position located between the manipulating position and the maximum withdrawal position.

19. The refrigerator of claim 1 , wherein a distance between the moving frame and the motor assembly is changed in proportion to a distance by which the connection member is withdrawn from the motor assembly.
