Abstract

Disclosed herein is a refrigerator including a body, a storage compartment formed in the body, a door which opens and closes the storage compartment, a damper that mitigates an impact, which occurs when the door is closed, and includes a cylinder, a piston that moves back and forth in the cylinder, and a pressurizing rod that transfers a pressure applied from the door to the piston, and a hinge that rotatably supports the door and includes a hinge bracket which connects the body to the door and a guide rail that guides a movement of the pressurizing rod.

First claim

What is claimed is:

1 . A refrigerator comprising:
a body; a storage compartment formed in the body; a door that opens or closes the storage compartment; a damper that mitigates an impact, which occurs when the door is closed, and comprises a cylinder, a piston that moves back and forth in the cylinder, and a pressurizing rod that transfers a pressure applied from the door to the piston; and a hinge that rotatably supports the door and comprises a hinge bracket which connects the body to the door and a guide rail that guides a movement of the pressurizing rod.

2 . The refrigerator of claim 1 , wherein the hinge bracket and the guide rail are separately provided and mutually coupled.

3 . The refrigerator of claim 1 , wherein the guide rail comprises:
a rail body coupled to the hinge bracket; and a guide portion that guides the movement of the pressurizing rod.

4 . The refrigerator of claim 1 , wherein the guide rail comprises a pair of guide walls that are provided on both sides of the pressurizing rod and extend in a movement direction of the pressurizing rod to guide the movement of the pressurizing rod.

5 . The refrigerator of claim 4 , wherein the guide rail comprises a guide path formed between the pair of guide walls.

6 . The refrigerator of claim 4 , wherein the guide rail comprises separation prevention grooves formed on the pair of guide walls to prevent a separation of the pressurizing rod.

7 . The refrigerator of claim 1 , wherein the pressurizing rod comprises a head portion pressurized by the door and guided by the guide rail.

8 . The refrigerator of claim 7 , wherein the head portion comprises a separation prevention protrusion that protrudes to prevent a separation from the guide rail.

9 . The refrigerator of claim 1 , wherein the door comprises a pressurizing roller portion that protrudes to pressurize the pressurizing rod.

10 . The refrigerator of claim 9 , wherein the pressurizing roller portion comprises:
a base portion coupled to a top side of the door; a roller installation portion that extends from the base portion; and a roller rotatably installed in the roller installation portion.

11 . A refrigerator comprising:
a body; a storage compartment formed in the body; a door that opens or closes the storage compartment; a hinge that rotatably supports the door; a hinge cover coupled to a top of the body to cover the hinge; and a damper that mitigates an impact, which occurs when the door is closed, and is coupled to the hinge cover.

12 . The refrigerator of claim 11 , wherein the damper comprises:
a damping device that performs a damping operation; and a damper housing that accommodates the damping device and coupled to the hinge cover.

13 . The refrigerator of claim 12 , wherein the damper housing comprises a first coupling portion that protrudes to be coupled to the hinge cover.

14 . The refrigerator of claim 13 , wherein the hinge cover comprises a second coupling portion coupled to the first coupling portion.

15 . The refrigerator of claim 11 , wherein the hinge cover comprises:
an upper wall; a sidewall portion that extends downward from an edge of the upper wall; and a hinge accommodating portion formed inside the upper wall and the sidewall portion, and wherein the damper is coupled to an inside surface of the upper wall.

16 . The refrigerator of claim 11 , wherein the hinge cover comprises an opening through which the damper passes.

17 . A refrigerator comprising:
a body; a storage compartment formed in the body; a door that opens or closes the storage compartment; a hinge that rotatably supports the door; a damper that mitigates an impact, which occurs when the door is closed; and a hinge cover coupled to a top of the door to form a hinge accommodating portion that accommodates the hinge and the damper.

18 . The refrigerator of claim 17 , wherein the damper comprises:
a moving part having a movement according to an opening and closing operation of the door; and a cylinder part fixed to the hinge cover regardless of the opening and closing operation of the door, and wherein the hinge comprises a guide rail that guides the movement of the moving part.

19 . The refrigerator of claim 17 , wherein the hinge cover comprises:
an upper wall; and a sidewall portion that extends downward from an edge of the upper wall, and wherein the damper is coupled to the upper wall.
