The purpose of shock mitigation is easily achieved. As it is severely exposed to the side portion, not only does not look good in appearance, but there is a problem that acts as an obstacle that the shock absorber is caught when the contents are put in or taken out.

In the latter case, a shock absorber is installed at the rear of the Kimchi refrigerator, and a compression spring and a torsion spring are built into the case in which the guide hole is formed to cushion the opening and closing of the door. The disadvantage is that.

On the other hand, the above-mentioned cited examples have the effect of the buffering effect when opening and closing the door, but there is also a problem that the sealing performance is not sufficient because the sealing action in the closed state of the door only depends on the weight of the door.

The present invention has been made in order to improve the problems of the conventional kimchi refrigerator door opening and closing structure as described above, the purpose is to solve the damage of the appearance beauty due to the external exposure of the door opening and closing device, the kimchi refrigerator door is simplified configuration It is to provide the opening and closing structure of the.

Another object of the present invention to provide an opening and closing structure of the kimchi refrigerator door excellent in the sealing performance of the contents in the closed state.

Opening and closing structure of the kimchi refrigerator door according to the present invention for achieving the above object, the kimchi refrigerator door opening and closing to open and close by connecting the main body of the kimchi refrigerator and the door hinged to the body with a gas spring provided with a cylinder and a rod. In the apparatus, the cylinder and the rod is rotatably installed in the rear end of the door and the main body rear part of the kimchi refrigerator so that the rod of the gas spring is directed downward, the center of the cylinder and the rod in the closed state An axis is inclined at a predetermined angle α with respect to the rear portion of the kimchi refrigerator body starting from the lower end of the rod, and the angle β formed between the center axis of the cylinder and the rod and the hinge of the door when the door is opened. It is a characteristic technical feature that is installed so that the 90 ° or more.

Here, the upper end of the cylinder may be coupled to the rear end of the door via a hinge, the lower end of the rod is provided with a ball socket to be coupled to the ball stud fixed to the rear portion of the main body.

In addition, the angle formed by the line connecting the hinge of the door and the lower end of the gas spring with respect to the center axis of the cylinder and the rod may be configured to a maximum of + 10 °, at least -10 °.

Hereinafter will be described in detail with reference to the accompanying drawings about the opening and closing structure and its operation of the kimchi refrigerator door according to the present invention.

1 and 2 are views showing the closed and open state of the door by the door opening and closing structure according to the present invention, respectively.

As shown in the figure, the door opening and closing structure according to the present invention is connected to the main body 10 and the door 11 of the kimchi refrigerator to the opening and closing device connected to the gas spring 20 provided with the cylinder 21 and the rod 22 Apply.

Conventional gas spring 20 is composed of a cylinder 21, a piston (not shown) and rod 22, an oil seal (not shown), oil, and other accessories, the nitrogen gas inside the cylinder 21 As the inert gas is sealed after being sealed, when the rod 22 is perturbed in the cylinder 21, a pressure difference occurs due to a change in the internal pressure according to the volume change of the cylinder 21, and thus a buffering action and attenuation. Action, speed control, and so on.

According to the present invention, the gas spring 20 as described above in the state in which the door 11 of the Kimchi refrigerator is rotatably coupled via the hinge 13 with the bracket 12 interposed between the main body 10. The cylinder 21 and the rod 22 are rotatably installed at the rear end of the door 11 of the kimchi refrigerator and the rear surface of the main body 10 so that the rod 22 faces the ground, that is, the downward direction.

In particular, the lower end of the rod 22 is provided with a ball socket 23 is coupled to the ball stud 30 is fixed to the back of the kimchi refrigerator main body 10, the hinge 31 is also provided on the upper end of the cylinder 21 As a result, it is coupled to the rear end of the door 11.

Above all, the most important feature of the present invention is that, as shown in FIG. 1, when the door 11 of the kimchi refrigerator is closed, a central axis L connecting the cylinder 21 and the rod 22 is provided at the lower end of the rod 22. As a starting point, the rear side of the kimchi refrigerator main body 10 is inclined backward. When the door is opened as shown in FIG. 2, between the center axis of the cylinder and the rod 1 and the hinge 13 of the door 11. It is installed so that the angle (beta) which makes | forms becomes 90 degrees or more.

Furthermore, as shown in FIG. 1, the hinge 13 of the door 11 and the gas spring lower assembly, that is, the ball stud 30, are connected with respect to the central axis ℓ connecting the cylinder 21 and the rod 22. In view of the sealing performance and the operating force of the door, it is preferable to configure the angle α of the connecting line to a maximum of + 10 ° and a minimum of -10 °.

The opening and closing of the kimchi refrigerator door by the installation structure is made as follows.

First, since the rod 22 of the gas spring 20 is installed downward, when the door 11 is opened, the cylinder 21 of the gas spring 20 expands in volume and the As the compressed gas and oil contained therein buffer and dampen, the door 11 is opened flexibly.

At this time, since the angle β formed between the center axis L of the cylinder and the rod and the hinge 13 of the door 11 is set to be 90 ° or more, the self-weight of the door 11 in the open state As a result, the load applied to the hinge 13 stays in a proper state so that the load on the hinge 13 supporting the door 11 is not excessive.

On the other hand, when the door 11 is closed, while the cylinder 21 of the gas spring 20 decreases in volume, the door 11 is smoothly closed by buffering and damping as in the case of opening the door 11, At this time, as the gas spring 20 is maintained inclined at a predetermined angle with the rear portion of the kimchi refrigerator main body 10 as described above, the door 11 by the weight of the door 11 and the load of the gas spring 20 ) Will increase the sealing force.

In particular, when the angle α formed by the line connecting the door hinge 13 and the ball stud 30 with respect to the center axis ℓ connecting the cylinder 21 and the rod 22 mentioned above is a '+' value The self-weight of the door 11 and the repulsive force of the gas spring 20 improves the sealing function, but when the door 11 is opened, the 'α' value becomes 0 ° while the gas spring 20 changes to the '-' value. The door 11 is to be opened automatically by pushing.

In addition, the 'α' value can be set according to the designer's intention of the sealing performance or the operating force of the door 11 (force applied by the user). When the sealing performance is important, the 'α' value is set to '+'. The larger the value, the better the sealing performance but the higher the operating force, which makes the user uncomfortable. In addition, when the operating force is important, the value of 'α' is set to '-' value, and the smaller the value, the smaller the operating force, while the sealing performance is lowered, so the minimum value of the 'α' value is -10 ° in terms of experience.

As described above, the opening and closing structure of the kimchi refrigerator door according to the present invention is a compact link structure using only the gas spring 20 to enable the door 11 to be opened and closed very flexibly and stably, the door 11 It also keeps the structure to improve the sealing force of the work very much.

The opening and closing structure of the Kimchi refrigerator door according to the present invention simplifies the configuration of the opening and closing device and reduces the external exposure of the opening and closing device, thereby improving the beauty of the appearance and sealing performance of the contents in the closed state. This is excellent and has the effect of contributing to maintaining the freshness of the stored contents.
