Moreover, in case that the user draws out a storage container of the same depth, it is lower by dimension A than that of a conventional structure of one, so it is easy to check the foods, etc., within the storage container 15, and it is easy of taking foods, etc., in and out, and besides a case ceases to occur such as that the user overlooks and forgets to use the foods, etc.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator having a drawer-type insulated door provided with a storage container for storing foods and the like on the back surface thereof.

[0002]

2. Description of the Related Art This type of refrigerator is disclosed in Japanese Patent Laid-Open No. 10-103.
No. 853, which is disclosed in FIG. 4 for convenience of storing foods and the like. That is, the drawer-type insulated doors tend to increase due to ease of organization and ease of use, and the drawer position is becoming higher with an increase in internal volume and diversification of storage temperature zones.

[0003]

However, in the above-mentioned prior art, since the heat-insulating door moves linearly, if the heat-insulating door is provided at a high position, the door obstructs the inside of the storage container drawn out. It is difficult to confirm foods and the like, and it is also difficult to put foods in and out. In addition, even if it is pulled out at a relatively low position (below the waist), if you do not pull it out enough, there is a blind spot on the front bottom part,
Sometimes they overlooked food and forgot to use it.

Accordingly, the present invention provides a refrigerator that can easily check foods and the like in a storage container even when an insulated door is provided at a high position, easily put in and take out foods and the like, and can avoid overlooking the foods and forgetting to use them. The purpose is to provide.

[0005]

For this purpose, the present invention comprises a storage container for storing foods and the like on the back surface thereof, and a heat insulating door which is drawn out in an arc shape.

The present invention also provides a refrigerator having a drawer-type heat-insulating door provided with a storage container for storing foods and the like on the back surface thereof, wherein the storage container is supported and has arcuate guide surfaces on both sides thereof. A first rail having a first roller at a rear end of the both sides, and a second roller guided to a guide surface of the first rail at a front end of each of inner surfaces of the refrigerator. And a second rail having an arcuate guide surface for guiding the first roller.

Further, according to the present invention, a stopper is provided at the front end of the guide surface of the second rail to limit the drawing out of the heat insulating door.

[0008]

Embodiments of the present invention will be described below with reference to the drawings. In FIG. 1, a refrigerator 1 has a box-shaped main body 2 having heat insulating walls on both sides except a front surface, a back surface, a ceiling surface, and a bottom surface. The main body 2 is formed by filling a heat insulating material such as urethane foam between an outer box made of a steel plate and an inner box made of a hard resin material.

The interior of the main body 2 is divided into a refrigerator compartment 3, two freezer compartments and a vegetable compartment by partition walls. The front opening of the uppermost refrigerator compartment 3 can be closed by a pivotable heat insulating door 4 that can be opened and closed, and the freezer compartment and vegetable compartment on the lower side of the refrigerator compartment 3 are drawer heat insulating doors 5, 6, and 7, respectively.

The heat insulating doors 4, 5, 6, and 7 are each formed by filling a heat insulating material such as urethane foam between a door outer box 8 made of a steel plate and a door inner box 9 made of a hard resin material. . Then, the first rail 1 made of metal having a U-shape in plan view is provided on the back surfaces of the heat insulating doors 5 and 6 of the freezer compartment, that is, on the inner box 9 of the door.
Fix 2 Both sides of the first rail 12 have an L-shaped cross section, and the back surface of the upper plate constitutes a guide surface 13. In addition, since both sides of the first rail 12 have an arc shape when viewed from the side, the guide surface 13 has an arc shape in which the front side and the back side are low. Further, first rollers 14 are respectively provided at rear ends of both sides of the first rail 12.

The heat-insulating door 5 and the first rail 12
And the heat insulating door 6 and the first rail 1
In the space formed by the storage container 2, storage containers 15 for storing foods and the like are fitted respectively, and are placed on the first rails 12 via flange pieces 16 protruding from the storage containers 15. You. The storage container 15 has a box shape with an open top surface, and the bottom surface and the upper end portion are made of a hard resin material having an arc shape when viewed from the side.

On the other hand, a second rail 20 having a U-shaped cross section is fixed to both side surfaces of the inner box of the refrigerator.
A second roller 2 guided by a guide surface 13 of the first rail 12 is provided at a front end of the inner surface of the second rail 20.
1 and arcuate guide surfaces 22 and 23 for guiding the first roller 14 are formed.

The guide surface 2 of the second rail 20
A stopper 25 is formed at the front end of the heat-insulating door 5 for restricting the heat-insulating door 5 from being pulled out, and the front side of the stopper 25 is cut off.

With the above configuration, when the heat insulating door 5 and the storage container 15 are pulled out as shown in FIG. 2, the second roller 21 of the second rail 20 is guided by the guide surface 13 and the first The first roller 14 of the rail 12 is guided by arcuate guide surfaces 22 and 23 and a stopper 25
According to the present embodiment, as compared with the conventional structure (linear movement of the storage container) in which the blind spot is generated in front of the storage container from the same viewpoint as shown by the diagonal lines, the heat insulating door 5 is positioned at the front. It is inclined, and the blind spot is smaller in front of the storage container 15, so that it is easy to overlook.

Further, as shown in FIG. 4, when the storage containers having the same depth are drawn out, the storage container 1 according to the present embodiment is reduced by the dimension A as compared with the conventional structure.
It is easy to confirm the food and the like in 5 and to easily put and take out the food and the like, and it is possible to avoid overlooking the food and the like and forgetting to use it. Further, in the latter half of the pulling-out operation, the user intends to open with his own weight. Note that the heat-insulating door and the storage container 15 having such a structure can be configured in multiple stages (two stages in the present embodiment).

Further, when the heat insulating door 5 is closed, the self-closing mechanism can be formed without a complicated mechanism because the second half of the operation is to be closed by its own weight, and it is possible to reliably prevent the cool air from flowing out of the refrigerator.

[0017]

As described above, it is difficult to close the heat-insulating door linearly obliquely downward to make it easier to check the food and the like in the storage container. Since the structure is such that it can be pulled out by itself, the latter half of the pulling-out operation attempts to open by its own weight, and the latter half of the closing operation tries to close by its own weight, so opening and closing is easy. Moreover, even if the heat-insulating door is provided at a high position, it is possible to provide a refrigerator in which foods and the like in the storage container can be easily checked, foods and the like can be easily taken in and out, and foods and the like are not overlooked and forgotten.
