Compressor 6 even when used in the kitchen installation
It is effective for the cooling and heat dissipation of the condenser 4.

[0008]

However, in the above-mentioned structure, in recent years, in order to reduce the wall thickness of the heat insulating layer and the capacity of the machine room by improving the internal volume efficiency of the refrigerator, the external size and the refrigerating capacity are reduced. As a result, the space for installing the compressor, condenser, and preheating pipe has become difficult.

Further, if the size is reduced for the purpose of forcibly mounting, not only the performance is deteriorated due to the reduction of cooling efficiency and the power consumption is increased, but also the long-term reliability is lost.

The present invention solves the above problems and relates to a refrigerator for forcedly cooling a compressor by using a blower.

[0011]

In order to solve the above-mentioned problems, the refrigerator of the present invention has a plate arranged in the entire width in the lower part of the refrigerator, a heat radiation pipe is provided under the plate, and behind the plate,
A compressor and a blower are arranged, and a suction port, through which the heat radiation pipe escapes, is provided in the plate in front of the blower.

[0012]

According to the present invention, the heat radiation effect of the heat radiation pipe and the cooling effect of the compressor are enhanced by the above-mentioned structure.

Indicates.

Reference numeral 30 is a compressor, 31 is a blower, 32 is a fan of the blower 31, 33 is a partition plate that divides the machine chamber 26 into two parts, left and right, and 34 is the compressor 30 and the blower 31 behind the plate 29. The mounting plate on which is arranged is shown. Two
Reference numeral 9a denotes an air suction port provided in the plate 29 at a position where the heat radiation pipe 28 escapes to reduce air convection resistance.

Reference numeral 35 is an evaporation dish arranged immediately below the compressor 30 for receiving defrosting water, 36 is a drain hose, 37 is a machine chamber cover, and 37a is an air discharge port provided in the machine chamber cover 37.

The arrow in the figure indicates the direction of air convection. The operation of the refrigerator configured as described above will be described.

The air taken in by the blower from the air suction port 29a of the plate 29 at the escape position of the heat radiating pipe 28 passes through the heat radiating pipe 28 and the plate 29, and the blower 3
1. Convection with the compressor 30 and blows air to the air outlet 37a provided in the machine chamber cover 37.

As described above, according to this embodiment, the plate 29 is arranged in the entire width of the lower part of the refrigerator, and the compressor 3 is provided behind it.
0, by disposing on the blower 31 and arranging the air suction port 29a in front of the blower 31, the heat radiation of the heat radiation pipe 28 and the cooling of the compressor 30 can be performed without being influenced by the width dimension of the refrigerator. It is effective.

As described above, according to the present invention, the plate is arranged in the whole width in the lower part of the refrigerator, the heat radiation pipe is provided under the plate, the compressor and the blower are arranged behind it, and the heat is radiated in front of the blower. By providing the air suction port that escapes the pipe, the heat dissipation effect of the heat dissipation pipe is enhanced by the large heat dissipation area, and the cooling effect of the compressor and the evaporation effect of the defrost water saucer are improved by the air blow from the blower. . Furthermore, since the plates are arranged over the entire width, the strength of the underbody as the structure of the refrigerator main body is improved. In addition, since the gap in the lower part of the refrigerator is reduced, it is possible to prevent mice from entering the machine room, and to prevent smoke and ignition due to electric wire galling.
