DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a drawer-type door for opening and closing a front opening of a storage room. The present invention relates to a storage provided with a container.

[0002]

For example, in a refrigerator, a lower container is provided on the back side of a drawer type door that opens and closes a front opening of a freezing room, which is a storage room, and is positioned above the lower container. There is a configuration in which an upper container movable in the front-rear direction is provided.

In such a configuration, the lower container is conventionally detachably supported by a support frame provided on the back of the door, and the lower container is moved relative to the freezing compartment as the door moves in the front-rear direction. To be put in and out. The upper container is slidably supported by upper container rails provided so that both flange portions provided at the upper end portions of the left and right side portions are provided on the left and right side surface portions of the freezer compartment so as to extend in the front-rear direction. The projections provided on the left and right sides of the bottom are slidably supported on support surfaces provided on the upper left and right sides of the lower container.

In the above-described conventional structure, when the upper container is moved in the front-rear direction, the distance between the flange portion and the upper container rail and the distance between the bottom convex portion and the support surface of the lower container are increased. There is a drawback that operability is poor due to large sliding friction.

In order to improve the operability of the upper container, rails guided by the upper container rail are provided on both left and right side surfaces of the upper container, and the rails roll on the upper container rail. It is conceivable to adopt a configuration in which the rollers are rotatably provided.

However, in such a case, it is necessary to separately provide dedicated rails on the left and right side surfaces of the upper container. Therefore, since the width of the upper container in the left-right direction is reduced, the capacity of the upper container is reduced. There is a problem that it becomes.

The present invention has been made in view of the above circumstances, and an object of the present invention is to improve the operability of an upper container in a device provided with a lower container and an upper container.
It is an object of the present invention to provide a storage that does not need to reduce the capacity of the upper container.

SUMMARY OF THE INVENTION In order to achieve the above object, a storage according to the present invention is provided with a storage room having an opening formed in a front surface thereof, and a storage room provided in front of the storage room so as to be movable in the front-rear direction. A drawer-type door that opens and closes the front opening of the storage room by moving in the front-rear direction, and is provided on the back side of this door,
A lower container that is moved into and out of the storage chamber with the movement of the door in the front-rear direction, and on both left and right side surfaces in the storage chamber, each is located above the lower container and extends in the front-rear direction. An upper container rail provided, an upper container disposed in the storage chamber positioned above the lower container, and having a flange portion on both left and right sides facing the upper container rail from above; It is characterized in that it comprises a roller rotatably provided on each of the left and right flange portions of the container, and a roller which rolls on the upper container rail as the upper container moves in the front-rear direction.

According to the above arrangement, rollers are provided on both right and left flange portions of the upper container, and these rollers roll with respect to upper container rails provided on both left and right side surfaces in the storage chamber. Therefore, operability when moving the upper container in the front-rear direction can be improved. Also, since the rollers are provided on both the left and right flange portions, unlike the case where special rails are separately provided on the left and right side surfaces of the upper container, it is not necessary to reduce the width of the upper container in the left-right direction, There is no need to reduce the volume of the upper container.

In this case, a guide surface extending in the front-rear direction is provided above the left and right sides of the lower container, and the left and right sides at the bottom of the upper container are provided on the guide surface with the movement of the upper container in the front-rear direction. It is preferable to provide a configuration in which a rolling lower roller is provided (the invention of claim 3).

According to the above-described embodiment, the following effects can be obtained. First, the upper container 50 is
In addition, since the upper container 50 is moved via the lower roller 62, the operability when moving the upper container 50 in the front-rear direction can be improved, and the storage in the lower container 33 can be easily taken in and out. it can.

In the upper container 50, the rear side of the left and right flange portions 54 and 55 is a so-called dead space, and in this embodiment, the rollers 58 are provided here. Unlike the case where dedicated rails are separately provided on both side surfaces, it is not necessary to reduce the width of the upper container 50 in the left-right direction.
It is not necessary to reduce the capacity. Moreover, the roller 58
Is configured to be directly attached to the support holes 57 formed in the flange portions 54 and 55, so that the number of parts is small and the configuration can be simplified.

The lower roller 62 of the upper container 50 is configured to fit into the fitting recess 37 of the lower container 33, and the upper container 50 is also pulled out when the door 30 is opened. Therefore, the usability of the upper container 50 can be improved.

The stopper 70 of the front lowering portion 69 of the upper container 50 is brought into contact with the front end of the upper container rail 40 from the front, thereby restricting the upper container 50 from moving further backward. So the upper container 5
Unlike the case where the rear end portion of the freezer abuts against the rear surface portion of the freezing compartment 8, the upper container 50 can be reliably positioned.

The right upper container rail 40 is set higher than the left upper container rail 40, and the right flange 55 of the upper container 50 is higher than the left flange 54. Since it is set, it is possible to prevent the upper container 50 from being inserted upside down, and to improve the capacity of the right storage portion 53.

Although the right flange portion 55 is set higher than the left flange portion 54, since the concave portion 71 is formed at a position from the rear portion of the right flange portion 55, the upper container 50 is formed. The operation for removing from the freezer compartment 8 can be easily performed.

The present invention is not limited to the above embodiment, but can be modified or expanded as follows. The present invention is not limited to the freezing compartment 8 and can be applied to the vegetable compartment 7.
