Description

[Detailed Description of the Invention] The present invention relates to a drain processing device for an air conditioner or the like, and particularly relates to an improvement of a dew tray for receiving ice from the drain.

Generally, the heat exchanger is placed directly on this dew pan, or
Alternatively, a structure is adopted in which the dew pan is attached to an amphoteric cutting plate that forms a heat exchange chamber, but in the former structure, the dew pan is fixed by the heat exchanger, so there is a drawback that it cannot be removed for cleaning etc. In the latter structure, the partition plates on both sides had to be made sturdy to support the weight of the heat exchanger, and both had problems.

In view of the above, the object of the present invention is to provide a drain treatment device in which a dew tray can be freely attached and detached, ice can be reliably received from the drain, and a heat exchanger can be easily mounted and fixed.

This project includes a main dew pan that is detachable and a plurality of auxiliary dew pans arranged and fixed on both sides. It is constructed by being fixed on a dew pan.

With this configuration, the heat exchanger is mounted and fixed astride the auxiliary dew pans on both sides, and the main dew pan can be attached and removed as needed.

An embodiment of the present invention will be described below based on the drawings. Fig. 1 is a plan view showing the internal structure of the guide side unit of an air conditioner, Fig. 2 is an exploded perspective view of the main parts, and 1 is an integral diaphragm unit. The main bottom frame is made of a sheet metal and has a shape, on which the compressor 2 is mounted, and a drain hole 3 is provided for discharging condensed water from a low-pressure pipe (not shown) connected to the compressor.

Reference numeral 4 denotes a sheet metal auxiliary bottom frame welded to the main bottom frame 1, which has a notch formed therein to form a recess 6 for storing ships in the sheet metal main dew pan 5, which is detachably attached to the sheet metal auxiliary dew pan 5. a, 7b in recess 6
It is placed on both side parts 8at8b of and fixed by welding.

The main dew pan 5 slides on rails 9, 9 integrally formed in the recess 6, and also serves as an auxiliary dew pan. The inner edges 10a and 10b of a and 7b are placed on the main dew pan 5, and the condensate condensed on the fins 12 of the heat exchanger 11 is directly transferred to the main dew pan 5.
The drain treatment device that receives water and condenses on the tube plates 13a and 13b on both sides is used as an auxiliary dew pan? After the water has been received by at7b, it is introduced into the main dew pan 5, and then passed through the drain hole 14 of the main dew pan 5 through a rehose (not shown) to an outdoor drain (not shown).
It is designed to be discharged.

The main dew pan 5 is removed during cleaning and to prevent condensate falling from the fins 12 from freezing during heating operations at low outside temperatures.

Reference numeral 16 denotes a hook welded and fixed across the center of one auxiliary dew pan 7b, and 17a and 17b are locking devices welded and fixed to two places on the left and right of the other auxiliary dew pan 7a. U-shaped piece 18 formed at the bottom of one tube plate 13b of 11
When the protruding piece 19 formed at the bottom of the other tube plate 13a is inserted into one of the locking tools 17a while engaging the hook 16, the heat exchanger 11 becomes an auxiliary dew pan. a,? b and is positioned and fixed astride the top.

If a heat exchanger 11' with a larger capacity is to be installed, the hook 16 can be used as is, and the protruding piece 19' can be attached to the other hook 17b, which is arranged according to the length of the heat exchanger.
Just insert and change.

In this way, by replacing the heat exchanger 11 and the compressor 2, the common outdoor unit can be used as is for different capacities such as 2 horsepower and 3 horsepower.

In addition, 20 is a blower that sends out outdoor air as shown by the arrow, and 21
．． 21 is a pedestal.

With the structure of the present invention as described above, the main dew pan can be attached and removed as needed, the drain can be reliably received by the main dew pan and the auxiliary dew pan, and the heat exchanger can be mounted on a sturdy bottom frame. It can be easily placed and fixed via the auxiliary dew tray.

In addition, by providing multiple locking tools for adjusting the tube plate fixing position on one of the auxiliary dew pans, heat exchangers of different lengths and large and small capacities can be incorporated and changed, making it possible to standardize the outdoor unit. .
