Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a drain processing device for a medium-sized or large-sized air-cooled heat pump type air conditioner.

Conventional configuration and its problems Air-cooled heat pump type air conditioner, 60 tons or
A drain processing device for an air-cooled heat pump type air conditioner of 80 tons or more is shown in FIG. 1 is a base, 2 is a compressor room, 3 is a semi-hermetic compressor, 4 is a water cooler/heater serving as a heat exchanger on the user side, 5 and 6 are provided on both sides,
A plate-type (air-cooled) outdoor heat exchanger on the unused side,
Completed.

8 is a box-shaped drain pan provided directly below the outdoor heat exchangers 5 and 6, and 9.10 is this drain pan 7.8.
11 is a blower.

Conventionally, the drain pan 7.8 is constructed like this, but because it is large and long in the longitudinal direction, if the slope is reversed or installed with a small slope, the drain port 9. , 10 to J:Il water is in poor condition, and a portion of the drain remains in the drain pan 7.8, and as time passes, the water storage portion of the drain pan 7.8 becomes severely corroded. For that reason, it is necessary to replace drain pan 7.8. .

At the time of this replacement, it had a drawback that it was difficult to replace it because it was box-shaped and installed directly below the outdoor heat exchangers 6, 6.

OBJECTS OF THE INVENTION The object of the present invention is to obtain a drain pan in which when drain falls into a drain pan, the drain is smoothly filled with water by υ1 without accumulating, and is less susceptible to corrosion.

Structure of the Invention In a large-sized air-cooled heat pump type air conditioner, both ends of the compressor room cover are provided so as to be located directly below the outdoor heat exchanger, and each end is provided with an inclined piece from the inside to the outside and a flat part. A mounting piece is provided that protrudes from the outer end surface of the outdoor heat exchanger, and a triangular drain pan is provided on this mounting piece, and the drain pan is mounted and fixed at an angle in one direction. It is.

DESCRIPTION OF EMBODIMENTS An embodiment according to the present invention will be described with reference to FIGS. 2 to 5. In Figures 2 to 6, 15 is the main body of the air-cooled heat pump type air conditioner, 16 is the blower for outdoor heat exchange installed on the top side, and 17.18 is the plate type installed at both ends. 1g of outdoor heat exchanger! '17';, 19,20
21 is a triangular drain pan, 21 is a base, 22 is an operating door, 23 is a pressure display bar 1, and 24 in FIG. 3 is a compressor room. A water cooler/heater 26 serving as a side heat exchanger, a liquid receiver (not shown), and the like are housed. Reference numeral 27 indicates a compressor room cover that is partitioned as the compressor room 24; 28 indicates inclined pieces provided at both ends of the compressor room cover 27, slanting from inside to outside; 29 indicates attachment of drain pans 19 and 20; This mounting piece 29
is provided to protrude from the outer end surface 30 of the outdoor heat exchanger 1, 18.

Further, the flat portion 31 is provided in flat contact with the base 21 to obtain stability. 32 is a drain pan 19 with a triangular cross section.
, a drain outlet provided at one end of 20; 33 is a screw for fixing the drain pans 19 and 20;
In order to lower the height of the screw hole t, the screw hole t is placed on an inclined line, and several screws are fixed. In addition, drain pan 19
, 20 are installed and fixed at the installation site, and are kept as separate parts during shipping and transportation.

In the above configuration, both ends of the compressor room cover 27 that become the hems are located directly below "1" of the outdoor heat exchanger 17.18,
An inclined piece 28 is provided at both ends of this position, and further extended,
A mounting piece 29 protrudes from the outer end surface of the outdoor heat exchanger 17.
A triangular drain pan 19 is attached to this mounting piece 29.
, 20 are mounted and fixed with screws 33 so that the drain port 32 side is lower. As a result, mainly during heating, when the condensed water that has adhered to the outdoor heat exchangers 17 and 18 drains and falls onto the inclined piece 28 and the flat part 31, the inclined piece 28
The water falling on the side picks up speed and falls on the drain pan 19 side,
Both the water flowing from the flat part 31 and the water falling from one side of the slope flow toward the drain pan 19 side. Drain pan 19
, 20 further flows to the drain port 32 side and is drained into a predetermined drain channel via a drain port (not shown) or the like. However, as described above, the drain pans 19 and 20 are fixed at the site using the threaded portions 33 after the main body is installed.

Effects of the Invention As described above, the present invention has a compressor room cover that has an inclined piece from the inside to the outside and a flat part on both ends located directly below the outdoor heat exchanger, and further extends to the outside of the outdoor heat exchanger. This is a drain processing device in which a mounting piece is provided protruding from the end face, and a triangular drain pan is provided on this mounting piece, and the drain pan is tilted so that the drain port provided on one side is lowered. The condensate that has condensed on the outdoor heat exchanger quickly flows through the inclined piece and the flat part to the drain pan, and within the drain pan, it is further quickly drained towards the drain port, and then from the inclined piece to the flat part and then to the bottom of the drain pan. Until then, the elements that cause drainage to accumulate can be eliminated, allowing for smooth drainage. Therefore, corrosion of the drain pan is also reduced, and even if the drain pan needs to be replaced, it can be easily replaced without any difficulty. Furthermore, with the trepan pan removed, transportation,
Since the drain pan can be carried in and transported separately, there is no need to remove the 11] of the main body, which has practical effects.
