DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a support structure for a refrigerator in a refrigerator or the like, and more particularly, to suspend a base on which the refrigerator is mounted in a cooler storage unit formed integrally with the refrigerator body. The present invention relates to a support structure for a refrigeration apparatus as described above.

[0002]

2. Description of the Related Art Cabinet is configured to be horizontally long as a refrigerator or a freezer (hereinafter simply referred to as "refrigerator") for storing fresh foods (hereinafter referred to as "foodstuffs") such as vegetables and fruits, meat and fish for a long time. Horizontal refrigerators are known. Inside the horizontally long box-shaped main body (cabinet), a storage room for cooling and storing food is defined. A machine room is provided adjacent to the side of the main body. The machine room is formed by forming a plurality of angle members arranged to protrude on the side of the main body into a frame shape, and disposing a panel on the outer surface of the frame body. On the base constituting the inner bottom of the machine room, a base plate is slidably mounted in the front-rear direction. On this base plate, a refrigeration system including a condenser, a cooling fan, a compressor and the like is provided. The refrigeration system is configured so as to be able to enter and exit the machine room integrally with the base plate. Above the inside of the machine room, there is housed an insulation box detachably mounted on the main body and communicating with the storage room, and a cooler and a fan inside the storage are arranged inside the insulation box. Then, the storage chamber is cooled by circulating and supplying the refrigerant from the refrigerating device to the cooler.

[0003]

A plurality of legs are disposed on the bottom surface of the refrigerator body, and the bottom surface of the refrigerator faces upward from the installation floor surface by a required height. In this case, since the machine room is constituted by a frame separately provided on the side of the main body, the legs are generally provided only on the main body side, and are housed in the machine room. The weight of the refrigeration apparatus to be used is to be supported by a frame. For this reason, when a heavy article is placed on the upper part of the frame or the work is performed on the upper part, the frame may be distorted by the weight. As a result, distortion also occurs in the base of the machine room on which the base plate on which the refrigeration apparatus is disposed is mounted, and large vibration and noise are generated during operation of the refrigeration apparatus, and this may cause a failure of the apparatus. There are drawbacks. Further, it is pointed out that if the distortion of the base becomes large, it becomes impossible to smoothly move the base plate and the refrigerating device into and out of the machine room. In addition, it is conceivable to provide the legs not only on the main body side but also on the machine room side. However, in this case, the number of parts is increased and the number of assembling steps is increased, which causes an increase in manufacturing cost. Further, since a frame having a size surrounding the heat insulating box in which the cooler and the internal fan are disposed is disposed on the side of the main body, the width of the machine room is increased.
As a result, it is pointed out that the refrigerator itself becomes large. When trying to reduce the size of the refrigerator, the internal volume of the storage room is reduced by the increase in the width of the machine room, which causes a disadvantage that the amount of stored foodstuffs is reduced. In addition, it is pointed out that the number of components constituting the machine room increases, the cost increases, and assembly takes time.

[0004]
