Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial field of application) The present invention has a drainage pipe housed inside to reduce the thickness and facilitate maintenance and inspection of the drainage pipe. The present invention relates to a vehicle air conditioner.

(Prior Art) The air conditioner is provided with a drain pipe for draining drain water generated in the heat exchanger (evaporator and condenser) to the outside, which is conventionally shown in FIG. As described above, it is generally practiced that the drain pipe 1 projects downward from the drain port 2a formed in the lower surface of the bottom plate 2 of the indoor unit A and the outdoor unit B, and is disposed below the bottom plate 2 in parallel therewith. It was being appreciated.

(Problems to be solved by the invention) However, since the drain pipe 1 is arranged, not only the height dimension as an air conditioner of about 50 mm is required under the bottom plate 2, but also the drain port 2a is provided. Since the air conditioners are oriented in the same direction, the height for the drainage pipe 1 is required over almost the entire length of the air conditioner, and the dimension for connecting the drainage pipe 3 is required, and the thickness as the air conditioner is required. However, there is a problem that the drainage pipe 1 increases considerably and the length of the drainage pipe 1 becomes long, so that maintenance and inspection cannot be easily performed when the drainage pipe 1 is clogged with dust. It was

In view of the above, the present invention provides a vehicle air conditioner that reduces the thickness of the air conditioner by changing the arrangement of drainage ports and drainage pipes for drain water drainage, and that allows easy maintenance and inspection of drainage pipes. The purpose is to provide.

[Constitution of device]

(Means for Solving Problems) In order to achieve the above object, the present invention has an indoor fan housed in an indoor unit in the front-rear direction, an indoor heat exchanger, and an outdoor heat exchanger housed in an outdoor unit. In a vehicle air conditioner that is embedded in a vehicle interior ceiling portion that is configured by sequentially arranging an air conditioner and an outdoor fan, the air conditioner is formed via a pair of rising side walls between an indoor heat exchanger and an outdoor unit. The indoor side intake port formed in the indoor unit bottom plate that opens to the indoor side, the drain pan part that is formed adjacent to the indoor side intake port and that houses the indoor heat exchanger, and the bottom plate from this drain pan part A drain pipe extending parallel to the bottom plate, a drain pipe extending parallel to the bottom plate from the heat exchanger on the outdoor side, and a drain port provided on each of the rising sidewalls. Air conditioner with tip outlet on the mouth It is characterized in that it is arranged so as to face the side of the table.

(Operation) In the vehicle air conditioner of the present invention, since the drain pipe is extended to the indoor intake port, maintenance and inspection of the drain pipe can be easily performed from the inside of the vehicle. It is possible to maintain and manage the inside of the drainage pipe, which is prone to occur, in an appropriate state where clogging of dust does not occur, and because the horizontal portion of the drainage pipe can be shortened, it is not necessary to maintain the height of the pipe, so the length of the drainage pipe can be shortened .

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

1 to 3 show an embodiment of the present invention, in which an air conditioner is composed of an indoor unit A and an outdoor unit B, and the bottom surfaces of both units A and B are closed by a bottom plate 2. There is.

Inside the indoor unit A, a compressor 3, an evaporator 4 as a heat exchanger, and an evaporator fan 5 are housed, and an indoor-side intake port 6 is bored in the bottom plate 2 so as to be located behind the evaporator fan 5. Is provided with an indoor air outlet 7.

Inside the outdoor unit B, a condenser 8 as a heat exchanger and an outdoor fan 9 are housed, and an outdoor inlet 10 and an outdoor outlet 11 are provided, respectively.

In the present invention, as shown in FIG. 4, a drainage pipe 1 for draining drain water generated from the evaporator 4 and the condenser 8 as the heat exchanger to the outside is projected below the bottom plate 2, This is to prevent the thickness of the air conditioner from increasing, and the following configuration is provided for this purpose.

That is, the bottom plate 2 has a concave drain pan portion 12 protruding downward.
Is formed in a bent shape, the evaporator 4 is housed inside the drain pan 12, and the drain pan 1
The convex portion 13 is bent and formed continuously to the convex portion 1.
A part of the top wall of 3 is cut off, and the indoor suction port 6 is formed therein.

Then, the rising side walls 13a, 13b of the convex portion 13
Drainage ports 14a and 14b are formed in each of them so as to face each other.

One drain port 14 communicating with the drain pan section 12
“A” is for draining the drain water of the evaporator 4 to the outside, and the drain pipe 1a on the indoor side is connected to this. The other exhaust port 14b opposite to the drain port 14a is for draining the drain water of the condenser 8 to the outside, and the drain pipe 1b on the outdoor side of the condenser 8 which is water-tight and connected thereto is inserted. Has been done.

Both drainage pipes 1a and 1b are arranged in parallel with the bottom plate 2 and are housed inside the convex portion 13, and
Both drainage pipes 1a and 1b are bent at a right angle with their tip outlets directed toward the sides of the air conditioner.

With this configuration, the indoor drain pipe 1a and the outdoor drain pipe 1b are housed inside the convex portion 13, that is, inside the air conditioner, and this projects from the bottom plate 2 downward. In addition to preventing this, drain water is discharged to the outside from the side of the air conditioner.

[Effect of device]

Since the present invention is configured as described above, by extending the drainage pipe to the indoor side intake port, maintenance and inspection of the drainage pipe can be easily performed from inside the vehicle, and dust clogging and scales are likely to occur. The inside of the drainage pipe can be maintained and managed in an appropriate state without clogging with dust.

Also, since the horizontal portion of the drainage pipe can be shortened, it is not necessary to make a difference in height of the pipe, so the length of the drainage pipe can be shortened, and the thickness as an air conditioner can be reduced by about 50 mm. Since the space for connecting the drainage pipe is not necessary and the projection under the bottom plate is eliminated, it is advantageous for the vehicle body frame arrangement.
