In addition, the second water guide roller 68 and the second vertical guide roller 62 may be positioned adjacent to each other to guide the sliding of the drawer container 60.

In addition, a second vertical guide 74 supported by the first vertical guide roller 90 described with reference to FIG. 2 is installed at the side of the drawer container 60.

The second vertical guide 74 has a shape similar to that of a panel that is substantially rectangular. That is, the second vertical guide 74 can be made in an inclined state. In addition, the second vertical guide 74 may be integrally formed with the drawer container 60.

4 is a perspective view schematically illustrating a state in which FIGS. 2 and 3 are combined. 4 is a state in which the drawer container is completely inserted into the inner case, one side of the inner case is omitted. A description with reference to FIG. 4 is as follows.

The first vertical guide roller 90 is located at the rear of the drawer container 60 to contact the second vertical guide 74. In addition, the first vertical guide roller 90 supports the weight of the rear of the drawer container (60).

The second vertical guide roller 62 is accommodated in the first vertical guide 82 and makes contact with the first vertical guide 82. In addition, the second vertical guide roller 62 supports the weight of the front of the drawer container (60).

That is, the rear of the drawer container 60 is supported by the first vertical guide roller 90, and the front of the drawer container 60 is supported by the second vertical guide roller 62. In other words, the drawer container 60 is supported vertically at a total of four points. This is because the left and right sides of the drawer container 60 should be considered together.

Therefore, even when food is accommodated in the drawer 60 and the weight is increased, the drawer 60 may be stably supported as compared with the related art. In addition, since the drawer container 60 is supported by the first vertical guide roller 90 and the second vertical guide roller 62 which can be rotated, the drawer container 60 can be easily slid.

On the other hand, the rear of the side of the drawer container 60 is guided to slide by the first water guide roller (96). In addition, the front of the side of the drawer container 60 is guided to slide by the second water guide roller (68).

Thus, the drawer container 60 is fixed at a total of four points with respect to the horizontal direction. This is because the left and right sides of the drawer container 60 should be considered together. Therefore, the lateral movement of the drawer container 60 can be prevented.

For example, if the drawer container is fixed at two points with respect to the horizontal direction, the lateral movement of the drawer container 60 cannot be prevented.

Because, when the drawer container is fixed at two points with respect to the horizontal direction it can be supported only at one point on the left, one point on the right. Then, the drawer container may be rotated by a predetermined angle in the left and right directions based on one point on the left side or one point on the right side. Therefore, the left and right movement of the drawer container can be generated.

In this case, the drawer container and the inner case may be deformed while the edge of the drawer container hits the inner case. Furthermore, each of the refrigerators may be broken so that the appearance of the refrigerator may not be beautiful. In addition, when the inner case is broken, unnecessary cold air may flow in or out through the broken part, which may cause a problem in storing food at a set temperature.

Figure 5 is a plan view showing the sliding operation of the drawer container according to the present invention. A description with reference to FIG. 5 is as follows.

The drawer container 60 may be slid into the inner case 40 and drawn in, or may be slid out of the inner case 40.

The refrigerator described above operates as described below.

When the drawer container 60 is drawn into the inner case 40, the first water guide roller 96 is rotated in contact with the inner case 40. In addition, the second water guide roller 68 is rotated in contact with the drawer container (60). One side of the drawer container 60 is fixed by two points, that is, the first water guide roller 96 and the second water guide roller 68, so that the left and right rotation of the drawer container 60 does not occur. Do not.

Since the first water guide roller 96 and the second water guide roller 68 are rotatably installed, the drawer container 60 can be easily slid.

In addition, the first vertical guide roller 90 supports the bottom surface of the second vertical guide 74, but rotates when the drawer container 60 is drawn into the inner case 40. Therefore, the friction between the first vertical guide roller 90 and the second vertical guide 74 is not large, it is possible to smoothly move the drawer container 60.

On the other hand, the second vertical guide roller 62 is accommodated in the first vertical guide 82 is rotated. That is, the second vertical guide roller 62 may be moved only along the inside of the first vertical guide 82. Therefore, the movement path of the drawer container 60 may be limited. Since the second vertical guide roller 62 is also rotatable, the friction between the second vertical guide roller 62 and the first vertical guide 82 is not large.

On the other hand, since the middle portion of the first vertical guide lower surface 86 is inclined at a predetermined angle, after passing through the middle portion of the first vertical guide lower surface 86, the second vertical guide roller 62 has the first vertical guide roller 62. The vertical guide is moved to be inclined at a predetermined angle along the lower surface 86. That is, since the drawer container 60 is moved to be inclined at a predetermined angle, the drawn state of the drawer container 60 is easily fixed.

In addition, when the drawer container 60 is fully inserted into the inner case 40, the second vertical guide roller 62 comes into contact with the first vertical guide vertical surface 88, and the second vertical guide. The roller 62 does not rotate and stops.

That is, the drawer container 60 is no longer drawn into the inner case 40 and stops in a fixed state.

In addition, since the drawer container 60 is slid out of the inner case 40 and drawn out, the description thereof will be omitted.

The present invention is not limited to the above-described embodiments, and as can be seen in the appended claims, modifications can be made by those skilled in the art to which the invention pertains, and such modifications are within the scope of the present invention.
