Description

Opening and closing device of home bar door for refrigerator {OPENING AND CLOSING DEVICE OF HOMEBAR DOOR FOR REFRIGERATOR}

The present invention relates to an opening and closing device of the home bar door, and more particularly, to smoothly operate the home bar door to open and close the door, thereby improving the operation of the door, and to reduce the required force when closing the home bar door. The opening and closing device of the home bar door for a refrigerator improved.

In general, recent refrigerators are provided with home bar doors on the doors of the refrigerators for large size, high quality, and energy saving.

The home bar door is configured to easily drink the contents, such as drinks, without opening the refrigerator door, as shown in Figures 5 and 6 rotatably coupled to the door of the refrigerator home bar door (50) And a link 51 provided to support the opening and closing of the home bar door 50.

In addition, the link 51 has a shaft 52 connected to the link 51 and the shaft 52 coupled to the link 51 to apply elasticity when the home bar door 50 is opened and closed, and a guide groove 53 formed in the door. It consists of a slider (54) for lifting up and down the spring, and a spring (55) provided to raise the slider (54).

That is, when the groove bar door 50 is opened, the slider 54 connected to the link 51 is lifted, and the link 51 and the groove bar door 50 are driven by the elasticity of the spring 55 connected thereto. By receiving the upward force, the home bar door 50 will be opened slowly.

However, as described above, when elasticity is applied to raise a link by a spring so as to open slowly when the home bar door is opened, it is difficult to precisely control the spring elasticity so that the opening and closing speeds of the home bar door are opened and closed. It becomes difficult to adjust, and there is a problem that the noise and impact increases when the home bar door is opened or closed.

Accordingly, an object of the present invention is to solve the above problems, it is possible to smoothly open and close the opening and closing of the home bar door to improve the operation feeling of the home bar door and to reduce the noise and shock generated when opening and closing the home bar door. An opening and closing device of a home bar door for a refrigerator is provided.

In order to achieve the above object, the present invention, in the opening and closing device of the home bar door comprising a link provided to support the opening and closing position of the home bar door installed to open and close the door of the refrigerator,

A first housing fixed to the groove bar door, a rotating member accommodated in the first housing and coupled with a link of the home bar door to rotate like a link, and compression and expansion of a spring when the rotating member is rotated. A first damping means configured to apply resistance to the rotation of the rotating member, a hydraulic member connected to the rotating member protruding into the through hole of the first housing, and interlocked with the hydraulic member; The second housing is fixed to the first housing, and the resistance is formed by the hydraulic pressure when the hydraulic member is rotated, and the damping force is formed together with the first damping means. And a second damping means configured to form.

As described above, the present invention has the advantage of improving the convenience of the user and improving the overall quality of the refrigerator by adjusting the opening speed of the home bar door to a fine and optimal state by using the elasticity and hydraulic pressure of the spring.

1 and 2 and 3 are a perspective view and an exploded perspective view and a cross-sectional view showing the opening and closing device of the home bar door for a refrigerator according to the present invention, the first housing (1) is fixedly installed in the home bar door (50), The rotating member 2 accommodated in the first housing 1 and coupled with the link 51 of the home bar door 50 to rotate together with the link 51 and the rotation member 2 when the rotating member 2 is rotated. First damping means configured to apply resistance to rotation of the rotating member 2 by compression and expansion of the spring 3, and a rotating member protruding into the through hole 4 of the first housing 1; 2) the hydraulic member (5) connected and rotated in conjunction with, and the chamber (6) is formed as much as the stroke to rotate and the home bar door (50) in the state in which the hydraulic member (5) is accommodated The second housing 7 fixed to the housing 1 and configured to form a resistance force by hydraulic pressure when the hydraulic member 5 is rotated. It consists of a second damping means.

That is, when the rotating member 2 is rotated by the link 51, the first damping force is generated by the elasticity of the spring 3 in the first damping means, and the hydraulic member 5 is rotated. The second damping force is generated, by combining the spring 3 having a mechanical elasticity difficult to adjust and the hydraulic pressure capable of relatively fine adjustment to form an appropriate damping force, the opening and closing speed of the home bar door 50 when opening and closing It is possible to fine-tune the power required to close.

The first damping means includes a first cam 8 formed on the rotating member 2, a second cam 9 formed to be coupled to the first cam 8, and a rotating member 2. In addition to being configured to move on the rotating member (2) in the penetrating state, it is made of a driving block (10) in contact with the spring (3).

The second damping means includes a first viscous fluid 11 filled in the chamber 6 and a first moving groove 12 protruding perpendicularly to the hydraulic member 5 and having a low portion. ) Is formed to be engaged with the engaging projection 13, the upper surface of the engaging projection 13, and the clearance 14 as much as D in the fitted state is formed and the first moving groove 12 and A second moving groove 15 is formed at one side so that the fluid can move through the play 14, and the other side is in close contact with the locking protrusion 13, and the blocking part 17 is configured to block the fluid. Consists of.

That is, when the hydraulic member 5 rotates to one side (the direction in which the home bar door is closed), the fluid 11 more easily moves to the opposite side of the blocking cover 17 through the first and second moving grooves 12 and 15. When the home bar door 50 is closed, the door bar can be closed with a small force. When the home bar door 50 is rotated in the opposite direction (the direction in which the home bar door is opened), the movement of the fluid is blocked by the blocking cover 17 to the fluid 11. The pressure is larger than when it is closed, so it opens slowly.

Particularly, the flange of the hydraulic member 5 bypasses the fluid to the opposite side of the blocking cover 17 at a position not corresponding to the moment of opening and closing the groove bar door 50 to reduce the damping force by hydraulic pressure. A bypass groove 18 is formed to allow the groove bar door 50 to open or close more quickly.

Of course, even if each of the first and second damping means is applied, the opening and closing of the home bar door 50 can be smoothly supported, but the adjustment is not fine compared to using the first and second damping means at the same time.

Referring to the operation and effect of the present invention as described above, when the door is opened while the home bar door 50 of the refrigerator is closed, the rotating member 2 connected to the link 51 rotates and is formed therein. The first cam 8 is rotated.

When the first cam 8 is rotated, the second cam 9 in close contact with this is pushed, and the driving block 10 moves to the left side in FIG. 3, and as the driving block 10 moves, the spring ( 3) is compressed, the compression elasticity of the spring (3) it is possible to primarily reduce the opening speed of the link 51, that is, the groove bar door (50).

In addition, the hydraulic member 5 installed to interlock with the rotating member 2 is rotated together, so that the blocking cover 17 fitted to the locking protrusion 13 rotates as shown in FIG. 4A. do.

When the blocking cover 17 rotates, the fluid 11 moves to the opposite side of the blocking cover 17 through the clearance between the second housing 7 and the hydraulic member 5 and the blocking cover 17. , Barrier cover 17 and the hydraulic member 5 is to be rotated slowly, as a result of the elasticity of the spring 3 and the damping force of the hydraulic pressure to open the home bar door 50 slowly.

When the blocking cover 17 is in the state as shown in FIG. 4C while the groove bar door 50 is opened, the fluid 11 is rapidly moved to the opposite side of the blocking cover 17 through the bypass groove 18, thereby providing this section. In the damping force of the fluid 11 is reduced the home bar door 50 is opened faster.

That is, since the bypass groove 18 is formed only in a certain section, the fluid moves quickly through the bypass groove 18 in this section, so that the damping force is drastically reduced to open or close quickly, and the rest of the section. In this case, the fluid 11 does not move quickly, so it opens or closes more slowly.

Particularly, when the home bar door 50 is closed again in the state in which the home bar door 50 is completely opened as shown in FIG. 4B, the home bar door 50 rotates in the direction of the B arrow in FIG. 4C, wherein the first and second moving grooves 12 and 15 And the clearance 14 formed between the inner surface of the blocking cover 17 and the locking protrusion 13 allows the fluid 11 to quickly move to the opposite side of the blocking cover 17, thereby reducing the damping force. When the home bar door 50 is closed, the home bar door 50 can be closed with a smaller force.

Of course, when the home bar door 50 is closed, there is no bypass groove 18 at the end thereof, so the damping force is increased, thereby preventing the home bar door 50 from being hardly closed.
