Abstract

Disclosed herein is a refrigerator including a sliding bar provided in each of a pair of doors and that moves between standby and contact positions to which the sliding bar moves from the standby position to seal a gap between the doors, and a moving device that operates the sliding bar in linkage with operations of opening and closing the doors, wherein the moving device includes a lever that is pressed by the main body and rotatably provided inside the doors to transmit a pressing force in a direction different from a direction in which the lever is pressed by the main body, and a sliding link that operates in linkage with rotation of the lever and configured so that the sliding bar moves between the standby position and the contact position. Through this configuration, the refrigerator minimizes noise related to opening and closing the doors and improves insulation performance.

First claim

What is claimed is:

1. A refrigerator comprising:
a main body having a storage compartment;
a pair of doors configured to open and close the storage compartment;
a sliding bar provided in each of the pair of doors, each sliding bar being configured to move in a first direction between a standby position and a contact position to which the sliding bar moves from the standby position to seal a gap between the pair of doors; and
a moving device configured to operate the sliding bar in cooperation with operations of opening and closing the doors, wherein the moving device includes:
a lever mounted for rotation about an axis inside each door and configured to rotate about the axis when pressed by the main body as the door is closed to transmit a pressing force to the sliding bar in each door; and
a sliding link configured to operate in cooperation with rotation of the lever and configured so that the sliding bar moves between the standby position and the contact position,

wherein the first direction, in which each sliding bar moves between the standby position and the contact position, extends along the axis of rotation of the lever.

2. The refrigerator of claim 1 , wherein:
the moving device further includes an intermediate link configured to operate in cooperation with the lever and provided to be movable in a second direction perpendicular to the axis of rotation of the lever when pressed by the main body; and
the sliding link is configured to convert movement of the intermediate link in the second direction into movement in the first direction in which the sliding bar moves between the standby position and the contact position.

3. The refrigerator of claim 2 , wherein the sliding link has one end rotatably provided in the intermediate link and an other end rotatably provided in the sliding bar.

4. The refrigerator of claim 2 , wherein the sliding bar remains parallel to the first direction.

5. The refrigerator of claim 2 , wherein the sliding link includes:
a first link rotatably provided in the intermediate link;
a second link configured to move relative to the first link; and
a link elastic member configured to generate an elastic force in a longitudinal direction in the sliding link between the first link and the second link.

6. The refrigerator of claim 2 , wherein the moving device further includes a lever elastic member provided to elastically return the lever and configured to generate an elastic restoration force in the second direction when the storage compartment is closed by the doors.

7. The refrigerator of claim 2 , wherein the moving device further includes an elastic member provided to elastically return the intermediate link and configured to generate an elastic restoration force in the second direction when the storage compartment is closed by the doors.

8. The refrigerator of claim 1 , wherein the lever is configured so that movement thereof is limited by an inner wall of the storage compartment when the storage compartment is closed by the doors.

9. The refrigerator of claim 1 , wherein:
the sliding bar includes a pair of sliding bars respectively provided in the pair of doors; and
the pair of sliding bars include first and second magnets disposed at opposite surfaces to come into contact with each other at the contact position.

10. The refrigerator of claim 9 , wherein the first and second magnets are configured to be spaced a predetermined distance apart from each other at the contact position.

11. The refrigerator of claim 1 , further comprising:
a housing forming a containing space so that the sliding bar is contained therein at the standby position; and
a sealing rib configured to divide the containing space.

12. The refrigerator of claim 11 , wherein the sealing rib extends in a longitudinal direction of the sliding bar and the housing and has one side fixed to the housing and an other side fixed to the sliding bar.

13. The refrigerator of claim 12 , wherein the sealing rib is provided to bend in accordance with whether the sliding bar is at the standby position or the contact position.

14. A refrigerator comprising:
a main body having a storage compartment;
a pair of doors configured to open and close the storage compartment;
a sliding bar provided in each of the pair of doors, each sliding bar configured to move in a first direction between a standby position and a contact position to which the sliding bar moves from the standby position to seal a gap between the pair of doors; and
a moving device provided in the doors to operate the sliding bar in cooperation with operations of opening and closing the doors, wherein the moving device includes:
a lever mounted for rotation about an axis inside each door and configured to rotate about the axis when pressed by the main body as the door is closed to transmit a pressing force to the sliding bar in each door;
an intermediate link configured to operate in cooperation with the lever and provided to be movable in a second direction perpendicular to the axis of rotation of the lever when pressed by the main body; and
a sliding link configured to operate in cooperation with the intermediate link and convert a pressing force transmitted in the second direction into movement in the first direction to move the sliding bar in the second first direction,

wherein the first direction, in which each sliding bar moves between the standby position and the contact position, extends along the axis of rotation of the lever.

15. The refrigerator of claim 14 , wherein the sliding link has one end rotatably provided in the intermediate link and an other end rotatably provided in the sliding bar.

16. The refrigerator of claim 14 , wherein the sliding bar is configured to move between the standby position at which the sliding bar is accommodated in the doors when the storage compartment is opened and the contact position to which the sliding bar moves from the standby position in the first direction to protrude from the doors when the storage compartment is closed.

17. The refrigerator of claim 14 , wherein the sliding bar remains parallel to the first direction.

18. The refrigerator of claim 14 , wherein:
the doors include an outer case and an inner case coupled to the outer case and having at least a portion accommodated in the storage compartment when the storage compartment is closed by the doors; and
the lever is provided to protrude higher than the portion of the inner case accommodated in the storage compartment and provided so that an operation thereof is restrained by an inner wall of the storage compartment in the storage compartment closed by the doors.

19. A refrigerator comprising:
a main body having a storage compartment; and
a pair of doors configured to open and close the storage compartment and having a bar assembly provided in each of the pair of doors and configured to fill a space between the pair of doors when the storage compartment is closed by the doors, wherein each bar assembly includes:
a housing forming a containing space;
a sliding bar configured to move in a first direction between a standby position at which the sliding bar is inserted into the containing space and a sealing position to which the sliding bar moves from the standby position to protrude from one door of the pair of doors toward an other door; and
a sealing rib configured to connect an inner surface of the housing forming the containing space to the sliding bar and extending in a longitudinal direction of the bar assembly to divide the containing space; an
