Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an outdoor unit of a cooling device having a compressor, a heat exchanger, and an accumulator.

[Conventional technology]

An outdoor unit of a conventional cooling device will be explained with reference to FIG.

In Fig. 6, 1 is an underframe, 1a is a drain hole formed in the underframe 1, 2 is a compressor installed on one side of the underframe 1, and 2a is a terminal installed on the upper side of the compressor 2. 3 is a heat exchanger installed on the other side of the underframe 1, 4 is a blower attached to the heat exchanger 3, 5 is a mounting plate for the blower 4, and 6 is a heat exchanger installed on the other side of the underframe 1. A partition plate 7 that partitions the exchanger 3 is an accumulator installed above the compressor 2, and the accumulator 7 is fixed to the partition plate 6 with a mounting plate 8.
9 is a control box, 10 is a cabinet, 11 is a service panel, 12 is a side panel, the underframe 1,
A compressor 2, a heat exchanger 3, a blower 4, and an accumulator 7 are housed in an interior surrounded by a cabinet 10, a service panel 11, and a side panel 12. In addition, the above-mentioned drain discharge hole 1a
is for discharging condensate dripping from the heat exchanger 3 to the outside of the outdoor unit during defrosting of frost that adheres to the heat exchanger 3 when the heat exchanger 3 acts as a cooler in the heat pump.

[Problem that the invention attempts to solve]

In the outdoor unit of the cooling system configured as described above, frost forms on the accumulator 7 depending on the operating state, and this frost melts during defrosting, and water droplets flow into the compressor 2.
There was a problem in that the wire could fall onto the top of the terminal 2a and enter the terminal portion 2a, causing an electrical leakage. Therefore, a heat insulating material may be wrapped around the accumulator 7 to prevent frost formation, but since the depth dimension A of the outdoor unit is small, wrapping the heat insulating material is difficult.

The purpose of this invention is to solve the above-mentioned problems and to provide an outdoor unit for a cooling device that prevents water droplets from entering the terminal section of the compressor without wrapping an insulating material around the accumulator. There is.

[Means for solving problems]

In this invention, in the outdoor unit of the cooling device as described above, a dew pan having a drain outlet opening on the outside of the compressor is installed between the compressor and the accumulator.

[Effect]

Since the outdoor unit of the cooling device according to this invention is constructed as described above, the water in which the frost adhering to the accumulator has melted is received in the dew tray and discharged from the drain outlet to the outside of the compressor. It is possible to prevent water from melting frost from entering the terminal section of the terminal.

〔Example〕

Hereinafter, embodiments of this invention will be described with reference to the drawings.

1, 2 and 3 show an embodiment of this invention. In these figures, the same parts as in FIG. 6 show corresponding parts, and 13 is a substantially box-shaped dew pan installed between the compressor 2 and the accumulator 7 and covering the lower surface of the accumulator 7. The dew pan 13 is inclined downwardly toward the partition plate 6, and is fixed to the vertical portion of the underframe 1 by a fixing plate 14. A drain outlet 13a is provided at the lowest part of the dew pan 13.
The drain outlet 13a is inserted into the square hole 6a of the partition plate 6, and its tip opening slightly protrudes from the partition plate 6 toward the heat exchanger 3. Note that the configuration of this device other than those described above is the same as that shown in FIG. 6.

Since the outdoor unit of this embodiment is configured as described above, the water droplets that fall when the frost adhering to the accumulator 7 melts during defrosting are transferred to the dew pan 1.
3, passes through the discharge port 13a, is discharged to the heat exchanger 3 side of the underframe 1 as shown by the arrow in Fig. 2, and is discharged to the outside of the outdoor unit through the drain discharge hole 1a of the underframe 1. Therefore, water falling from the accumulator 7 does not enter the terminal portion 2a of the compressor 2.

FIG. 4 shows a modification of the dew pan 13. This dew pan 13 is provided with a tubular drain outlet 13a, and is used in the same way as the dew pan 13 of the embodiment shown in FIGS. 1 to 3.

FIG. 5 shows another embodiment of this invention. In this embodiment, the dew pan 13 is inclined so that the side opposite to the partition plate 6 is lower, and a drain outlet 13a is formed at the lowest part of the dew pan 13 that protrudes toward the outer circumference of the compressor 2. A drain discharge hole 1b is formed in the underframe 1 to face the drain hole 13a.
The configuration of this embodiment other than the above is the same as that of the embodiment shown in FIGS. 1 to 3. and,
In this embodiment as well, the water droplets that fall when the frost adhering to the accumulator 7 melts during defrosting are transferred to the dew pan 1.
The water that falls from the accumulator 7 does not enter the terminal portion 2a of the compressor 2.

[Effect of idea]

As explained above, according to this invention, the water from the melted frost adhering to the accumulator placed above the compressor is received in the dew pan, and this water is discharged through the drain outlet provided at the lowest part of the dew pan. Since water can be discharged to the outside of the compressor, it is possible to prevent water from entering the terminal section of the compressor without wrapping an insulating material around the accumulator.
