Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention relates to an air conditioner that uses a heat exchanger and a compressor to perform air conditioning, and particularly to a housing that houses the heat exchanger and the compressor. Drainage structure.

(Prior Art) A conventional drainage structure will be described with reference to FIG.

In the conventional waterproof structure, a drain pan 72 is installed below the heat exchanger 71, and drain water or the like collected by the drain pan 72 is to be discharged to the outside from a discharge pipe 74 inserted into the housing 73.

(Problems to be solved by the invention) However, in the conventional drainage structure, it is necessary to bend the discharge pipe somewhere because the diameter of the discharge pipe cannot be large because the volume inside the housing is limited. However, there is a problem that the discharge pipe is closed due to foreign matter such as dust.

Therefore, in the present invention, it is a technical subject to dispose a discharge pipe having a large diameter so as not to be affected by the volume in the housing.

[Constitution of device]

(Means for Solving the Problems) Technical means taken to achieve the above-mentioned technical problems include a first housing for accommodating a heat exchanger and a housing arranged below the first housing for accommodating a compressor. A second housing, a drain pan disposed between the first housing and the second housing, and a first housing that is disposed outside the second housing such that the upper end communicates with the drain pan and the lower end opens. And at least one hollow column that is a drain pipe.

(Operation) According to the above-mentioned technical means, the drain water or the like discharged from the first housing is collected by the drain pan and discharged by the hollow support as the discharge pipe. Since the hollow struts are located outside the housing, the diameter of the hollow struts can be large independent of the housing volume. Therefore, according to the above-mentioned technical means, it is possible to arrange the discharge pipe having a large diameter without being affected by the volume in the housing.

By the way, when the hollow support pillar is bent, foreign matters such as dust are likely to be accumulated therein, and the hollow support pillar is easily closed.

Therefore, in the device according to the second aspect, the hollow column has a straight shape.

Then, even if foreign matter such as dust enters the hollow support, the hollow support is unlikely to be closed.

Apart from that, in order to improve the mechanical strength and the appearance design of the second housing, it is necessary to appropriately determine the cross-sectional area and the shape of the hollow column.

Therefore, in the device according to the third aspect, the hollow column is formed by using the extruded aluminum material.

Then, the shape of the hollow column can be freely designed, and the cross-sectional area and cross-sectional shape of the hollow column can be appropriately determined.

(Embodiment) A preferred embodiment to which the present invention is applied will be described below with reference to the accompanying drawings.

FIG. 1 is a perspective view depicting the device of this embodiment.

The first housing 1 has a roof panel 3 and two heat exchangers 2.
And two side panels (not shown) and drain pan 6
Is equipped with. The space in the first housing 1 is the heat exchanger chamber
Is 10. The two heat exchangers 2 are fixed so as to face each other. The side surface of the first housing 1 is surrounded by the heat exchanger 2 and side panels (not shown). A roof panel 3 is fixed above the heat exchanger 2. Two fans 4 are fixed on the roof panel 3.

A second housing 5 is arranged below the first housing 1. The second housing 5 includes a drain pan 6, a bottom plate 8 and four side panels (not shown). The space inside the second housing 5 is a machine room 11. A compressor (not shown) and the like are arranged in the machine room 11.

The drain pan 6 is arranged between the first housing 1 and the second housing 5. The drain pan 6 has four hollow columns 7
It is fixed to the upper end of a, 7b, 7c, 7d.

FIG. 2 shows an AA cross-sectional view of the hollow column 7b. Hollow brace 7b
Is made by extruding an aluminum material. The hollow columns 7b are anodized to prevent rusting for a long period of time. The ends 72b and 73b of the hollow column 7b are ribs for fixing the side panel. Note that the other hollow columns 7a, 7c, 7d are exactly the same as the hollow columns 7b, so a description thereof will be omitted.

A partial plan view of the drain pan 6 as viewed from B is shown in FIG. As shown in the drawing, side panels are fixed to the ends 72b and 73b of the hollow column 7b. A recessed portion 6b is provided at the corner of the drain pan 6. The recess 6b is the upper opening 70 of the hollow strut 7b.
facing b. The width of the recessed portion 6b is substantially the same as the width of the upper opening 70b of the hollow column 7b.

Rainwater, snow, dust, and the like enter the heat exchanger room 10. Further, drain water is generated from the heat exchanger 10. Heat exchanger room
Drain water that has entered the 10 is collected by the drain pan 6, and flows into the upper openings 70a, 70b, 70c, 70d of the hollow columns 7b from the recessed portions 6a, 6b, 6c, 6d by gravity, and the hollow columns 7a, 7
It is discharged from the lower openings 71a, 71b, 71c, 71d of the hollow columns 7a, 7b, 7c, 7d through the insides of b, 7c, 7d.

In this embodiment, the four hollow columns 7a, 7b, 7c and 7d have exactly the same functions. Therefore, even if a hollow pillar
Even if one of the 7a, 7b, 7c, 7d is closed by dust or the like, the remaining hollow columns 7a, 7b, 7c, 7d can quickly drain the drain water or the like. Therefore, the drain pan 6 is not corroded, and drain water or the like overflows from the drain pan 6 without contaminating the outer appearance of the second housing 5.

In addition, in this embodiment, an example in which an aluminum extruded material is used as the hollow columns 7a, 7b, 7c, 7d has been introduced, but a steel pipe or the like can also be used as the hollow columns 7a, 7b, 7c, 7d.

Further, various shapes can be used as the cross-sectional shape of the hollow columns 7a, 7b, 7c, 7d. As the cross-sectional shape of the hollow columns 7a, 7b, 7c, 7d, the shapes as shown in FIGS. 4, 5 and 6 can be considered.

[Effect of device]

According to the present invention, the diameter of the hollow column can be increased regardless of the volume of the housing. Therefore, even if foreign matter such as dust enters the hollow conduit, it is difficult to close the empty conduit.

Also, by disposing the drainage pipe on the outside of the second housing, compared to the case where the drainage pipe is provided on the inside of the housing, it is advantageous in terms of space without interfering with other parts, and therefore drainage is facilitated. The tube can be straightened. As a result, the conduit is more difficult to close.

In addition, since the first housing is supported by the hollow pillar that serves as a drainage pipe, the hollow pillar can also have a function of discharging drain water and the like in the drain pan to the outside and a function of supporting the first housing. There is no need to newly install a supporting member, resulting in cost advantage.
