Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a refrigerator shelving apparatus suitable for improving the strength of a shelf for vertically partitioning a storage room of a domestic refrigerator having a large width.

[0002]

2. Description of the Prior Art Prior to the present invention, Shokai 60-6378
Japanese Patent Laid-Open Publication No. 0-202 discloses a refrigerator in which both sides and front and rear parts of a shelf net formed by a combination of metal rods are covered with pieces made of synthetic resin in order to prevent damage to a resin inner box of a freezer.

[0003] The Japanese Utility Model Publication No. 60-415, which precedes the present invention.
No. 05 publication discloses that both sides of the inner box can be removed so that the shelf can be removed without pulling out the resin shelf to the position where it is completely removed from the inner box, and the door opening angle is not limited to 90 ° or more. The upper and lower beads are formed so as to face each other vertically, and are surrounded by the outer peripheral frame portion composed of both side portions supported on the both lower beads and a rear side portion having a rising dimension higher than these side portions. Refrigerator, etc. that consists of a container-shaped resin shelf, removes the corners at the lower rear end of both sides of this shelf, and sets the spacing between the upper and lower beads to the same level as the height of the rear side. Rack support device is disclosed.

[0004]

In the former publication mentioned above, since the portion which becomes the placing portion of the food has a shelf net structure, the filth or liquid dropped from this placing portion, Meuno Food, is placed. Since it cannot be received by the storage unit, it will be extremely unsanitary for food, such as falling down the shelf net to stain the food below or permeating the inside of the food to deteriorate the food etc. There was a problem. Since the shelf net is formed by combining metal rods, there was no particular problem in terms of strength of the placed article against fruit juice.

On the other hand, in the latter publication mentioned above, since the shelf has a container shape, it is possible to receive dirt from food on the shelf. Since recent refrigerators have become larger and the width of the heat insulating box tends to be larger, the width of the shelves partitioning the heat insulating box into upper and lower parts is also increasing. In particular, since the shelves are made of resin, the larger the width dimension is, the more easily the shelves are bent and the load-bearing strength is easily lowered. Therefore, this shelf is divided into two on the left and right to support each shelf separately, one is made of resin and the other is made of metal or glass, and a metal reinforcing frame is attached to the peripheral edge of the shelf. It is necessary to make some efforts to improve the strength of the shelves.
However, if the shelves are divided into two left and right, the number of supporting members increases, and in addition, there is a problem that the effective internal volume decreases due to the presence of supporting arms on the back wall of the box that are in the zenpo. Further, although the strength of the entire shelf is improved by providing a metal reinforcing frame on the peripheral edge of the shelf, the reinforcing frame rubs the side wall of the inner box and causes abnormal noise when the articles are placed, or the inner box is cracked. Problems such as occurrences were likely to occur. Further, the work of placing and fixing the shelf container on the reinforcing frame is troublesome, and there is a problem that the weight of the shelf is greatly increased and it becomes difficult to attach and detach the shelf. If one of the shelves is made of resin and the other shelf is made of metal, the same problem as in the above-mentioned company-wide publication will occur.

Therefore, in the present invention, in addition to improving the strength of a resin-made shelf having an article mounting portion, it is possible to provide a shelf device for a refrigerator provided with a reinforcing member which is easily attached to the shelf. With the goal.

[0007]

According to the present invention, in a refrigerator in which a supporting portion for supporting a shelf for partitioning a storage chamber into upper and lower portions is formed on a side wall of the storage chamber, a front side portion of a peripheral side wall of the shelf supported by the supporting unit is provided. The present invention provides a shelf device for a refrigerator, which has a substantially U-shaped metallic reinforcing member to be attached, and has both left and right ends of the reinforcing member supported by the supporting portions.

Further, according to the present invention, in a refrigerator in which a support portion for supporting a shelf for partitioning a storage chamber into upper and lower parts so as to be movable back and forth is formed on a side wall of the storage chamber, the shelf has a flat plate member having a peripheral side wall, and the flat plate member. Of a refrigerator in which the plate member is provided with protrusions protruding in the left-right direction and placed on the front machine support portion, and both left and right ends of the reinforcement member are fixed to the protrusions. A shelf device is provided.

[0009]

According to the present invention, since the reinforcing member is attached to the front portion of the peripheral side wall of the shelf, the reinforcing member can be reduced in size and weight, and both left and right ends of the reinforcing member are formed on the side wall of the storage chamber. Since it is supported by the supporting part, the structural strength of the front part of the shelf can be improved and the strength of the peripheral side wall part placed on the supporting part can be improved, and the reinforcing member also serves as the front decoration member of the shelf. It is possible.

According to the second aspect, since the left and right ends of the reinforcing member can be fixed by utilizing the protrusions of the shelf supported by the supporting portion provided on the side wall of the storage chamber, it is possible to fix the reinforcing member specially. In addition to omitting the fixing member, it is possible to improve the strength of the front side wall and the left and right side wall front portions of the shelf, and to simplify attaching and detaching the reinforcing member.

Further, the reinforcing member 86 can also be used as a decorative member in the front part of the shelf 82, and the design of the shelf is improved.

[0037]

According to claim 1 of the present invention, since the metal reinforcing member attached to the front portion of the peripheral side wall of the shelf is substantially U-shaped, the size and weight can be reduced as compared with the conventional reinforcing frame. Since the left and right ends of the reinforcing member are supported by the supporting portions, the strength of the front portion of the shelf and the strength of the portion supported by the supporting portions can be improved. In particular, the reinforcing member can also be used as a front decoration member for the shelf.

According to the second aspect of the invention, since the left and right ends of the reinforcing member are fixed by utilizing the protrusions projecting laterally from the peripheral side wall of the shelf, the fixing member of the reinforcing member can be omitted, and the front of the shelf can be omitted. The strength of the side walls and the front portions of the left and right side walls can be improved, and the work of attaching and detaching the reinforcing member can be simplified.
