Description

[Detailed description of the invention] (a) Industrial application field This invention relates to a drain treatment device that is incorporated into a ceiling-embedded or ceiling-suspended air conditioner.

(b) Conventional technology As a device for discharging drain water generated in a heat exchanger from a drain pan to the outdoors, if a large drain slope cannot be maintained, the drain pump is used as an air conditioner as shown in Japanese Utility Model Application Publication No. 15924/1983. This system is installed inside the aircraft and pumps the drain water collected in the drain pan above the air conditioner.

(c) Problems to be solved by the invention When repairing or replacing the drain pump, the drain pump cannot be removed from the air conditioner without lowering the air conditioner from the ceiling, making service work troublesome.

The present invention provides a drain processing device for an air conditioner in which a drain pump can be easily attached and removed while the air conditioner is installed on the ceiling.

(d) Measures to solve the problem This proposal is an air conditioner in which a heat exchange chamber containing a built-in heat exchanger and drain pan and a blower chamber containing a built-in fan are separated by a partition plate. An opening is provided to accommodate the drain pump from the ventilation chamber to the heat exchange chamber.

(e) Action If you open the ventilation grill of the ventilation chamber, remove the drain pump in the heat exchange chamber from the ventilation chamber, and take it out of the air conditioner through the open part of the ventilation grill, you can drain the air conditioner while it is still installed on the ceiling. We can repair and replace pumps.

(F) Embodiment Figure 1 is a cross-sectional view of a ceiling-mounted air conditioner incorporating the proposed device, and Figure 2 is a vertical cross-sectional view of the air conditioner taken along the -' arrow direction in Figure 1. The inside of the main body 1 is divided into a heat exchange chamber 2 and a ventilation chamber 3 by a partition plate 4,
A heat exchanger 5, a drain pan 6, and a drain pump 7 are built into the heat exchange chamber 2, and a centrifugal fan 8, a fan casing 9, and a fan motor 10 are built into the ventilation chamber 3.

11 is a wind direction changing blade 1 communicating with the heat exchange chamber 2;
The air outlet 13 with two air outlets is a suction ventilation grill that can be opened and closed and communicates with the ventilation chamber 3, and is provided on a decorative panel 16 that closes the ceiling hole 15 of the ceiling board 14, and the indoor air sucked in from the ventilation grill 13. After being sucked into the fan casing 9, it is pushed out by the fan 8 into the heat exchange chamber 2 through the outlet 17 of the fan casing 9 that penetrates the partition plate 4, is cooled by the heat exchanger 5, and is blown out from the outlet 11. be done.

Due to this cooling operation, drain water generated in the heat exchanger 5 accumulates in the drain pan 6, is pumped up by the drain pump 7, is guided to the upper part of the main body 1 through the drain hose 18, and is then discharged outdoors.

FIG. 3 is a perspective view of essential parts of the air conditioner showing how the drain pump 7 is installed, and FIG. 4 is a perspective view of the drain pump 7. An opening 19 is cut out in a part of the partition plate 4, and A part of the drain van 6 is extended from the opening 19 toward the ventilation chamber 3 side, and this extended portion 2
While positioning the drain pump 7 at the opening 1
A drain pump 7 is fixed to a blind plate 21 that closes the drain pump 9 from the side of the ventilation chamber 3 with a mounting fitting 22.

With this configuration, if the drain pump 7 becomes clogged or breaks down, the air filter 2 can be removed while the air conditioner is still installed on the ceiling plate 14.
3 and rotate the ventilation grill 13 as shown by the chain line in FIG. 2, insert your hand into the ventilation chamber 3, and remove the four screws 24. After that, the blind plate 21 is installed in the ventilation chamber 3.
When the mounting bracket 2 is moved diagonally upward to the side, the mounting bracket 2 is attached to the blind plate 21.
The drain pump 7 fixed at 2 is moved to the ventilation chamber 3 through the opening 19, and the drain pump 7 and the blind plate 21 are pulled out from the opening where the ventilation grill 13 is opened, so that the drain pump 7 can be repaired or replaced. . still,
When taking out the drain pump 7 from the heat exchange chamber 2, the drain pump 7 can be taken out without any problem if the drain hose 18 is removed from the drain pump 7, or if the drain hose 18 is made to have a flexible structure.

The drain pump 7 can be installed by performing the reverse operation, and the flange pieces 25, 25 of the blind plate 21 are crimped to the two sides of the opening 19 with the screws 24, and the other flange piece 26 is attached to the side plate of the main body 1. The lower edges of the blind plates 21 are pressed against the drain pans 6, so that the opening 19 is sealed by the blind plates 21.

(g) Effects of the invention According to this invention, an opening for housing the drain pump was provided in the partition plate that separates the heat exchange room and the ventilation room, so the air conditioner could be left installed on the ceiling during service. Able to install and remove drain pumps.

Moreover, since we used the ventilation room, which is a dead space, as a work space to store the drain pump in the heat exchange room, the air conditioner does not have to grow in size. This device is most suitable for ceiling-mounted air conditioners that can only be used for work.

Additionally, if the drain pump and the blind plate are integrated, it is possible to more easily attach and detach the drain pump.
