However, when the closing speed of the storage box is increased, the speed at which the cover closes the storage box is also increased. In particular, when the weight of the cover is heavy, the strength of the cover closing the storage box is also increased, so that the cover is closed when the storage box is closed. I was shocked.

This caused a loud noise, and the storage box or cover was also damaged.

The present invention is to solve the above problems, an object of the present invention is to provide a refrigerator that can mitigate the impact of the cover to close the storage box when closing the storage box and prevent the occurrence of noise.

       In order to achieve the above object, the refrigerator according to the present invention is a main body, a storage box which is opened and closed by sliding in the main body, a shelf covering a part of the storage box, hinged to the shelf and the storage box Rotating according to the entrance and the opening and closing of a portion of the storage box, characterized in that it comprises a shock absorber to mitigate the impact of the cover hit the storage box when the storage box is closed.

In addition, the shock absorber is characterized in that the one side is fixedly supported on the shelf, the other side is a torsion spring is fixedly supported on the cover.

In addition, the torsion spring is characterized in that it is formed to have a greater restoring force as the storage box is changed from an open state to a closed state.

In addition, the storage box is formed with a guide portion and the cover is characterized in that the projection is guided to the guide portion to rotate the cover is formed.

In addition, the guide portion is characterized in that it comprises a groove portion accommodated in a state in which the projection is laid down, a flat portion supported in the state in which the projection is standing and the inclined surface connecting the groove portion and the flat portion.

Hereinafter, a refrigerator according to an exemplary embodiment of the present invention will be described in detail with reference to the accompanying drawings.

As shown in FIG. 1, the refrigerator according to an embodiment of the present invention may include a main body 10, a refrigerating chamber 11, and a freezing chamber 12, each of which is divided into two sides and includes a refrigerating chamber 11 and a freezing chamber 12. The refrigerator compartment door 13 and the freezer compartment door 14 are rotatably installed on both sides of the main body 10 so as to be opened and closed.

The main body 10 includes a compressor (not shown) for compressing a refrigerant at a high temperature and a high pressure, a condenser (not shown) for cooling with heat exchange with air, an expansion device (not shown) for expanding under reduced pressure, and a refrigerating chamber 11. And a refrigeration cycle component such as an evaporator (not shown) for cooling the air inside the freezer compartment 12, and the cool air generated in the evaporator is discharged through the cold air outlet 15 provided at the rear of the main body 10 to store the refrigerator compartment ( 11) and the freezing chamber 12.

The refrigerating chamber door 13 and the freezing chamber door 14 are provided with a rack 16 for storing a container such as a bottle. In the refrigerating chamber 11 and the freezing chamber 12, various kinds of foods can be partitioned and stored. A plurality of shelves 17 are installed. In particular, a lower portion of the refrigerating chamber 11 is provided with a storage unit 20 which is a space for separately storing foods requiring freshness such as vegetables or fruits.

As shown in FIG. 2, the housing 20 has an upper opening and a shelf 17 and a shelf 17 covering most of an upper portion of the storage box 30, which are opened and closed by sliding in the front-rear direction. ) Is hinged by the hinge shaft 42 and rotates as the storage box 30 slides forward and backward and includes a cover 40 that opens and closes an upper portion of the storage box 30.

A handle 31 is formed on the front side of the storage box 30 so that the storage box 30 can be easily gripped by hand, and the side of the storage box 30 when the storage box 30 slides in the front and rear directions. The rail 32 is formed so that it may be guided by the protrusion (not shown) provided in the side wall of 11.

As described above, the opened upper portion of the storage box 30 is covered by the shelf 17 and the cover 40, which is to seal the storage box 30 to maintain a constant humidity in the storage box 30. to be.

In addition, the reason why the upper part of the storage box 30 is covered by using the cover 40 which is a separate member from the shelf 17 is that the cover 40 is rotated even when the storage box 30 is pulled a little. This is to form the space 35.

When the storage box 30 is pulled to open the storage box 30 as described above, the cover 40 opens the storage box 30 and the cover 40 pushes the storage box 30 to close the storage box 30. In order for the 40 to close the storage box 30, the guide part 36 is formed on the upper side of the storage box 30, and the protrusion 40 is guided according to the shape of the guide part 36. 41 is provided.

The guide portion 36 includes a groove portion 36a formed at the front and a flat portion 36b formed at the rear, and an inclined surface 36c connecting the groove portion 36a and the flat portion 36b. As described above, the guide part 36 is formed in the storage box 30, and the protrusions 41 are formed in the cover 40, so that the cover 40 is slid in the front-rear direction so that the cover 40 is accommodated in the storage box 30. ) Will be opened and closed.

First, when the storage box 30 is pulled to open the storage box 30, the projection 41 of the cover 40 is guided along the inclined surface 36c while being supported in a standing state on the flat part 36b, so that the cover ( 40 rotates in a clockwise direction about the hinge shaft 42, and thus the cover 40 opens the storage box 30.

However, when the storage box 30 is pushed to close the storage box 30, the protrusion 41 of the cover 40 is received along the inclined surface 36c and accommodated in a state lying down in the groove 36a. 40 is rotated counterclockwise around the hinge axis 42 and the cover 40 is to close the storage box 30.

When the storage box 30 is pushed to close the storage box 30 as described above, the cover 40 hits the storage box 30 and noise is generated, and the storage box 30 or the cover 40 is damaged. The shock absorbing member as shown in FIG.

In the present embodiment, the torsion spring 50 is used as the shock absorbing member. However, in addition to the torsion spring 50 of the present embodiment, another member may be used as long as it prevents the cover 40 from hitting the storage box 30 strongly. .

The center 50a of the torsion spring 50 used in the present embodiment is inserted into the hinge shaft 42 and one side 50b is fixedly supported on the shelf 17, and the other side 50c is fixed on the cover 40. Supported.

In addition, the torsion spring 50 is in a state in which one side 50b and the other side 50c are relaxed in a vertical state, and a state in which one side 50b and the other side 50c are in equilibrium with each other has a restoring force.

4A and 4B show the operation of the cover 40 provided with the torsion spring 50 as described above.

As shown in FIG. 4A, when the storage box 30 is pulled to open the storage box 30, the protrusion 41 of the cover 40 rises along the inclined surface 36c formed on the guide part 36 and is flat. Since the cover 40 is rotated in the clockwise direction about the hinge shaft 42, the cover 40 opens the storage box 30. At this time, the torsion spring 50 is in a state in which one side 50b and the other side 50c are perpendicular to each other, and the torsion spring 50 is maintained in a relaxed state.

However, as shown in FIG. 4B, when the storage box 30 is pushed to close the storage box 30, the protrusion 41 of the cover 40 descends along the inclined surface 36c formed in the guide part 36. Since the cover 40 is located in the groove 36a, the cover 40 is rotated counterclockwise about the hinge shaft 42 and thus the cover 40 closes the storage box 30.

At this time, the torsion spring 50 has a restoring force gradually because one side (50b) and the other side (50c) is changed to a state parallel to each other in a state perpendicular to each other, the cover 40 is generated because the force to return to the original state The impact on the storage box 30 is alleviated.

As described above in detail, according to the refrigerator according to the present invention, when the cover closes strongly against the storage box, noise may be prevented from being damaged or broken.
