A conventional refrigerator will be described with reference to FIGS. 4 to 8. The refrigerator 1 has a box-shaped main body 2 having heat insulating walls on both side surfaces except the front surface, the back surface, the ceiling surface, and the bottom surface. The main body 2 is configured by filling a heat insulating material 2C such as urethane foam between an outer box 2A made of a steel plate and an inner box 2B made of a hard resin material.

The inside of the main body 2 is divided into a refrigerating compartment 3, a vegetable compartment 4 and two freezing compartments 5 and 6 by partition walls. The front opening of the uppermost refrigerating compartment 3 can be closed by a rotatable insulation door 7 that can be opened and closed, and the front opening of the vegetable compartment 4 and the freezing compartments 5, 6 below the refrigerating compartment 3 can be of a pull-out type. It is closed by heat insulating doors 8, 9 and 10, respectively.

The heat insulating doors 7, 8, 9 and 10 are constructed by filling a heat insulating material 11C such as urethane foam between a door outer box 11A made of a steel plate and a door inner box 11B made of a hard resin material. There is. A storage container 13 for storing food or the like is attached to the back surfaces of the vegetable compartment 4 and the freezer compartments 5, 6, that is, the inner box 11B. X indicates the position of the center of gravity of the storage container 13.

First rails 14 made of metal are provided on both sides of the storage container 13, and a first roller 15 is provided at the rear end thereof. Second rails 17 for guiding the first rollers 15 are provided on both inner side surfaces of the refrigerator body 2, and the second rails 1 for guiding the first rails 14 are provided at the front end portions thereof.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the drawings. The refrigerator to which the present invention is applied is the same as the conventional refrigerator shown in FIGS. 4 and 5, and the description of the overlapping portions will be omitted.

In the refrigerator of the present invention, the difference from the conventional refrigerator is that, as shown in FIGS. 1 to 3, in the second rail 17 in which the first roller 15 is slidably guided while rotating. The groove 20 is that the groove upper wall 20A is inclined upward from the rear intermediate position to the front.

That is, as shown in FIG. 2, when the heat insulating door 8 is pulled out forward, while the center of gravity position X of the storage container 13 is in front of the second roller 18, the heat insulating door 8 is the same as the conventional one.
And the storage container 13 is pulled out straight forward, but when the center of gravity position X of the storage container 13 passes the second roller 18, the first roller 15 slides on the upwardly inclined surface of the groove upper wall 20A and the groove lower wall. Since it separates from 20B, the heat insulation door 8 and the storage container 13 are gradually pulled out while inclining downward.

Then, as shown in FIG. 1, when the heat insulating door 8 and the storage container 13 are fully pulled out, the heat insulating door 8 and the storage container 13 rotate downward about the second roller 18 and are inclined. Therefore, the second roller 18 is locked to the step 29 of the first rail 14.

On the contrary, when the heat insulating door 8 is pushed in, the first roller 15 is guided by the second rail 17 while rotating and sliding on the upward inclined surface of the groove upper wall 20A, and at the same time, the second roller 18 is moved. The first rail 14 is guided while rotating, and the heat insulating door 8 gradually becomes horizontal from the inclined state and then returns to the original position. Therefore, it is possible to return to the original position only by the normal pushing back operation, without having to purposely lift the heat insulating door 8.

As described above, since the groove upper wall 20A (sliding surface) of the second rail 17 with respect to the first roller 15 is inclined upward from the rear to the front, it is accommodated when the heat insulating door 8 is pulled out. Since the container 13 is inclined downward, it is easy to visually recognize foods or the like inside the storage container 13 that are particularly in front, and even when the storage container 13 is at a relatively high position such as the vegetable compartment 4, It is possible to prevent food items from overlooking and to prevent food items from decaying.

Further, when the center of gravity X of the storage container 13 comes to the front of the second roller 18, the storage container is made to incline downward, so when the food in the back of the storage container 13 is taken out, it is stored. It suffices to pull the container 13 straight out, and when the heat insulating door 8 is fully opened, the second roller 1
Since the storage container 13 is rotated downward and tilted about the storage container 8, the storage container 1 is opened when the heat insulating door 8 is fully opened.
The front side of the storage container 13 is visually wide, and the user can see the entire inside of the storage container 13 in a natural state while standing, which is excellent in usability.

Of course, not only the vegetable compartment 4 but also the freezer compartments 5 and 6 located at a lower position than this can have the same drawer structure.

Although the embodiments of the present invention have been described above, various alternatives, modifications, and variations can be made by those skilled in the art based on the above description, and the present invention can be carried out in various ways without departing from the spirit of the invention. It is intended to cover alternatives, modifications or variations.
