Description

[Detailed description of the invention] This invention relates to improving the drainage structure of an air conditioner that is installed through a window or wall, and its purpose is to facilitate maintenance and inspection of the drainage structure. This is one of the

Conventionally, as shown in Fig. 1, this type of air conditioner has an outer box attached so as to protrude indoors and outdoors through a wall a, and a pair of opposing rails C on both sides of the bottom of the outer box. established,
On this rail C, a board d1 a compressor e1 an indoor heat exchanger f
It had a structure in which a cooling unit consisting of 1 outdoor heat exchanger g1 fan motor h1 fans ij, etc. was mounted and housed so as to be slidable (approachable and retractable).

When necessary, such as during service, the cooling unit is pulled out for maintenance and inspection work.

On the other hand, the condensed water that has condensed on the indoor heat exchanger f etc. is shown in Figure 2.
As shown in FIG. 3, the water is temporarily stored on a substrate d, flows through a drainage hole k provided in the substrate d to a receiver m removably attached to the bottom of the outer box, and is discharged to the outside.

Therefore, when draining water during inspection or repair, for example, the receiver m can only be moved in a direction perpendicular to the bottom of the outer case, which means that the cooling unit cannot be completely removed from the outer case. The work cannot be done unless it is removed, and the workability is extremely poor.

Moreover, at that time, some of the condensed water that has accumulated on the indoor side may be spilled, causing problems.

The present invention eliminates the drawbacks found in the above-mentioned conventional air conditioners.

Hereinafter, FIGS. 4 to 4 of the attached drawings showing one embodiment of the present invention.
This will be explained with reference to FIG.

In FIG. 4, reference numeral 1 denotes a wall of a building that partitions an indoor side 2 and an outdoor side 3.

Reference numeral 4 denotes an outer box having open front and rear surfaces and a bottom surface, and is fixed to the wall 1 with the front and rear surfaces passing through holes provided in the wall 1 both indoors and outdoors.

Here, the mounting fittings for fixing the outer box 4 to the wall 1 are omitted because they are not necessary for the explanation.

5 is a cooling unit, which includes a substrate 6, a partition plate 7 vertically provided on the substrate 6, a compressor 8, an outdoor heat exchanger 9, an indoor heat exchanger 10, a fan motor 11, and a motor mounting base 12.
, a propeller fan 13, a multi-blade fan 14, etc.

The cooling unit 5 is slidably mounted on a pair of rails 15 provided on both sides of the bottom surface of the outer box 4 so as to extend in the penetrating direction, and can be pulled out to the indoor side 2 by a handle 16.

Therefore, since most of the main parts are built into the cooling unit 5, inspections, repairs, etc.
This can be done by pulling it out from the outer box 4 and removing it.

Reference numeral 17 denotes a water tray installed at the lower part of the indoor heat exchanger 10, and a groove portion 18 is formed in a part thereof so as to pass through the partition plate 7 and guide dehumidified water to the outdoor side of the substrate 6.

Reference numeral 19 denotes a drain port formed on the bottom surface of the substrate 6 on the outside of the room.

This drain port 19 part is the drain port 1 as shown in Fig. 4 and Fig. 6.
A constriction part 25 that projects inward is formed around the drain port 19, and a drain lid 26 having a drain hole 26a in the center is inserted into the drain port 19.

Further, on the bottom surface of the outer box 4, when the board 6 is housed in the outer box 4, a drainage tray mount 29 is provided that protrudes toward the center and has a substantially semicircular hole 29a that opens at the center directly below the throttle section 25. ,
The position of the hole 29a is set so that the center of the drain lid 26 coincides with the center of the hole 29a.

Reference numeral 27 denotes a funnel-shaped water receiver having a groove 27a on its outer periphery, and is detachably supported by the fixture 29 by fitting the groove 27a into the hole 29a.

28 is a drainage pipe, which is attached to the water receiver 27.

In the above configuration, when inspecting, repairing, etc., before pulling out the unit 5 to the indoor side 2, remove the drain receiver 27 from the drain tray mount 29 on the outdoor side 3, and pull out the drain M26 from the constriction part 25. By doing so, the dehumidified water can be drained, and if the water drain cover 26 is inserted again after draining the dehumidified water, the water level of the accumulated ice will be lowered from D to E, so when the unit 5 is pulled out to the indoor side 2. , there is no fear of water spilling,
Work can be easily performed on the indoor side 2.

Furthermore, the amount of dehumidified water required to cool the outdoor heat exchanger 9 can be adjusted by attaching and detaching the water drain lid 26 to and from the throttle part 25.

As is clear from the above embodiments, the drainage structure of the wall-penetrating air conditioner according to the present invention is such that the drainage device that receives condensed water from the cooling unit can be removed from the outdoor side, and maintenance and inspection work can be carried out. When performing this, the water from the cooling unit can be drained by first removing the drain from the outside, so compared to the conventional method where the cooling unit is removed from the outer box and then drained, it is possible to drain the condensed water indoors. It has various advantages such as no spillage and extremely good workability.
