Abstract

The present invention is applicable to " a combination structure of links (5, 8) and a cylinder (4); Structure connected to the top and bottom of the refrigerator door; When the door of the refrigerator is opened for more than one angle, the links 5 and 8 move according to the movement of the door so that the piston 3 compresses the cylinder 4 and the compressed cylinder 4 moves the links 5, 8, the links 5, 8 receiving the compressive force transmit the force in the direction opposite to the moving direction of the door of the refrigerator, and the contact force and the compressive force transmitted to the piston 3 and the cylinder 4 cancel each other And the force of the door is reduced so as to buffer the shock.

Description

Refrigerator door dampeners

The present invention relates to a refrigerator door shock absorber, and more particularly, to a refrigerator door shock absorber having a door (5, 8) 4) a refrigerator door shock absorber which functions to counteract the door of a refrigerator by the action reaction action law of motion.

Conventional techniques that can serve as a buffer for a door include a shock absorber using spring force, a shock absorber using a link and a cam, and a shock absorber using a sealer hydraulic pressure.

More specifically, according to the prior art related to the present invention, the door hinge device for a door of Korean Patent No. 10-0742354 controls the rotation speed of the door by using the elasticity and restoring force of the spring in accordance with the rotation of the shaft. However, it is impossible to fix the door due to the resilience of the spring, and when considering a refrigerator door that opens and closes dozens of times a day, wear due to physical friction between the fixed cam and the rotating cam is expected.

Korean Patent Laid-Open Publication No. 10-2004-0067145 discloses a refrigerator having an opening / closing control device for a refrigerator door, a link bar moving forward and backward in the case of a refrigerator, a hinge-coupled link bar, and a control device for adjusting the forward / The opening angle of the refrigerator door can be adjusted and maintained in multiple stages. However, the multistage control device is inconvenient because it can not provide smooth door opening to the user.

[Patent Document 1] Korea Patent No. 10-0742354 "Buffer hinge device for door ", 2007.07.27 [Patent Document 2] Korean Published Patent Application No. 10-2004-0067145 "Opening and Closing Control of Refrigerator Door and Refrigerator ", 2009.05.08

none.

It is an object of the present invention to provide a refrigerator door shock absorber which allows a refrigerator door shock absorber to be realized with a simple structure.

In order to solve the above problems, the present invention provides a refrigerator comprising a link 5 provided on a refrigerator body, a link 8 connecting the refrigerator body and the door, and pins 1, 2, 6, -bar mechanism. Further, the refrigerator body is provided with rails which serve as paths of the driving pins 1 and 2, and a cylinder 4 and a piston 3, which serve as buffer for the rails, are provided. The present invention is characterized in that a buffering effect occurs in the door of the refrigerator due to the action of the 4-bar mechanism, the piston (3) and the cylinder (4).

The refrigerator door shock absorber according to the present invention has the following effects.

1. A simple and durable structure makes it possible to buffer the refrigerator door.

2. Noise is low due to the linkage structure of the hydraulic cylinder.

3. Due to its structural characteristics, it can be used for all doors such as Kimchi refrigerator, front door.

1 is a perspective view of a refrigerator door shock absorber according to the present invention.
2 is a plan view of a refrigerator door shock absorber according to the present invention.

Hereinafter, a refrigerator door shock absorber according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a refrigerator door shock absorber according to the present invention, and FIG. 2 is a plan view of a refrigerator door shock absorber according to the present invention.

The refrigerator door shock absorber according to the present invention comprises a link 5 installed in a refrigerator main body, a link 8 connecting the door of the refrigerator main body and doors, and pins 1, 2, 6, 7) are combined to form a 4-bar mechanism.

When the refrigerator door (9) is opened above a certain angle, the connected links (5, 8) rotate on the door axis to compress the piston (3). The compressed piston 3 transmits the force as much as it is compressed to the links 5, 8 by the law of action reaction. The links (5, 8) to which the force is transmitted transmit the force in the direction opposite to the moving direction of the refrigerator door. As the force of the door is reduced by canceling the two forces, the compressive force of the piston (3) becomes smaller as the force of the door is reduced, so that the force is balanced at the maximum angle and the buffer effect is produced.

In addition, the refrigerator door shock absorber according to the present invention is characterized by its combination structure of the links (5, 8) and the cylinder (4), and thus can be utilized in various applications such as a kimchi refrigerator door and a doorway door.

Hereinafter, a refrigerator door shock absorber according to the present invention will be described in detail with reference to the accompanying drawings. The refrigerator door shock absorber according to the present invention can vary the operating angle of the piston 3 and the cylinder 4 due to the adjustment of the length of the links 5 and 8 by the combination structure of the links 5 and 8 and the cylinder 4 Can change. Accordingly, the claims of the present invention include modification and modification of the operating angle of the piston (3) and the cylinder (4) according to the adjustment of the length of the links (5, 8).
