Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vegetable box opening / closing device for a refrigerator, and more particularly, to conveniently storing food in a vegetable box of a refrigerator and completely adhering a vegetable box door to a main body by its own weight.

[0002]

2. Description of the Related Art In a conventional refrigerator, as shown in FIGS. 1 and 2, a vegetable box 6 for storing foods such as vegetables is formed in a lower portion of a main body 1a. The vegetable box can be opened and closed by a vegetable storage door 3a.

When the vegetable storage door 3a is pushed into the main body 1a, a suction force acts between the magnetic material attached to the door gasket (not shown) and the iron plate of the main body 1a.
Therefore, the vegetable storage door 3a is in close contact with the main body to maintain the heat insulating state.

[0004]

However, when the magnetic force of the door gasket drops due to long-term use, the vegetable storage daore 3a is imperfectly adhered to the main body 1a, and the cold air is cooled by the main body 1a.
Is leaked to the outside. That is, there arises a problem that the electric power loss of the refrigerator is caused, the cold air efficiency of the refrigerator is lowered, and the reliability of the product is lowered.

The present invention is to solve the above problems, and provides a vegetable box opening / closing device for a refrigerator in which food can be easily stored in the vegetable storage and the vegetable storage door is completely brought into close contact with the main body by its own weight. The purpose is to

[0006]

In order to achieve the above object, a vegetable box opening / closing device of the present invention is provided in a lower part of a refrigerator main body for storing vegetables and for guiding movement of the vegetable box. A guide rail fixed to the lower wall of the main body, a slider that is inserted into the guide rail and has a number of rollers, and is attached to both sides of the vegetable box, and rotates the roller when the vegetable box is inserted or removed. When the support member and the vegetable box are completely inserted into the lower part of the body of the refrigerator, the gravity type locking means for connecting the support member to the guide rail by the weight of the vegetable box. It is characterized by being composed of and.

Example 1 Example 1 of the present invention will be described with reference to the drawings. 3 is an exploded perspective view showing the present invention, FIG. 4 is a vertical sectional view showing a combined state of FIG. 3, and FIG. 5 is a vertical sectional view showing an operating state of the present invention.

Guide rails 2 are fixedly provided on both sides of the inner case wall surface in the lower portion of the main body 1, and an upward projecting portion 2a is formed at one front end of the guide rail 2. Inside the guide rail 2 is provided a slider 5 that makes a forward and backward linear motion when the vegetable storage door 3 is opened and closed. A plurality of rollers 4 are mounted on the slider 5. The support member 7 is connected to the vegetable storage door 3, and the vegetable box 6 is mounted inside. The support member 7 moves together with the slider 5 by the frictional force of the roller 4 when the vegetable storage door 3 is opened and closed, and a guide long groove 8 connected to the upper surface of the roller 4 is formed on one side. A stopper 9 for pressing the slider 5 when the vegetable storage door 3 is closed is formed at the upper part of the front end of the support member 7, and an inclined surface 7a corresponding to the upward projecting portion 2a of the guide rail is formed at the lower part of the front end. It is formed. An upward protrusion that protrudes higher than the guide rail in front of the guide rail and a front of the slider, and when the vegetable box is completely inserted in the lower part of the refrigerator, the direction of gravity on the inclined surface of the upward protrusion. The roller which receives the force of and constitutes a gravity type locking means.

The operation of the present invention thus constructed is as follows. When the user tries to open the vegetable storage door 3 below the main body 1 of the refrigerator, the vegetable storage door 3 is pulled in the state as shown in FIG. The roller 4 of the slider 5 contacted between the upward protruding portion 2a of the guide rail 2 and the lower inclined surface 7a at the front end of the guide long groove 8 on both sides of the support member 7 is attached to the front end of the guide rail by frictional force. It moves forward while getting over the formed upward protruding portion 2a.

As shown in FIG. 5B, when the supporting member 7 is moved together with the slider 5 so that the roller 4 in front of the slider 5 comes out of the main body 1, the vegetable box 6 is joined to the supporting member 7 by its own weight. Since the vegetable storage door 3 hangs downward, the user can conveniently store the stored food in the vegetable box 6.

When the user presses the vegetable storage door 3 in order to close the vegetable storage door 3 in the state shown in FIG. 5B, the support member 7 moves to the right and the support member A stopper 9 formed on the upper part of one front end of 7 presses the slider 5. When the roller 4 of the support member 7 gets over the upward projecting portion 2a of the guide rail 2, the whole of the support member 7 and the vegetable storage door 3 is slightly raised to the main body as shown in FIG. Since it is in close contact with No. 1, cold air is prevented from leaking.

[0012]

As described above, according to the present invention, when the vegetable storage door 3 at the bottom of the body 1 of the refrigerator is opened, it opens slightly downward, so that the user can conveniently store the stored food. . In addition, according to the present invention, the vegetable storage door 3 is completely brought into close contact with the main body 1 due to the weight of the vegetable storage to prevent cold air leakage. As a result, the efficiency and reliability of the product are greatly improved.
