Then, the liquid refrigerant is transferred to the indoor heat exchanger 7 through a capillary tube (not shown) and heat-exchanged to generate cold air. The cold air is blown into the room from the blower 9 for the cold air by the indoor blower 8 to cool the room.

In particular, the inside and outside of the indoor cover 14 are pressurized or depressurized in accordance with changes in atmospheric pressure and a load is applied to the entire indoor cover 14, so that the grid-like reinforcing ribs 14a are formed. Are reinforced with.

[0007]

However, in the inside and outside of the indoor cover 14 of the vehicle air conditioner described above, a load is applied to the entire indoor cover 14 by pressurization and depressurization as the atmospheric pressure changes. Due to the relationship, the above indoor cover 1
4 and the reinforcing ribs 14a may cause cracks due to metal fatigue, and the reinforcing ribs 14a
Therefore, it is difficult to attach the heat insulating material 15 to the inside of the indoor cover 14 while avoiding this.

The present invention has been made in view of the above-mentioned circumstances, and cracks are generated inside and outside the cover even if a load is applied to the entire cover due to pressurization or decompression due to changes in atmospheric pressure. It is an object of the present invention to provide an air conditioner for a vehicle, in which the heat insulating material on the inside of the cover is easily attached and labor is saved by mass production.

[0009]

SUMMARY OF THE INVENTION The present invention is a vehicle air conditioner installed on the ceiling side of a vehicle, wherein a main body of the vehicle air conditioner is provided with a cover body, and the cover body is provided. A punching reinforcement cover is attached to at least the inner surface of the main body.

[0010]

According to the present invention, the punching reinforcing cover is attached to the cover body so that the pressure applied to the entire cover by pressure or pressure reduction due to atmospheric pressure change is evenly distributed so that the cover body is not cracked. In addition, the heat insulating material on the inside of the cover can be easily attached to save labor in mass production.

The present invention will now be described with reference to the illustrated embodiments.

The present invention will be described by giving the same reference numerals to the same constituent members as those of the above-described specific example.

1 to 3, reference numeral 1 is a main frame of a vehicle air conditioner installed on the ceiling side of a vehicle traveling at high speed. The main frame 1 has an indoor heat exchange chamber. 2, the machine room 3 and the outdoor heat exchange room 4 are the partition members 5a, 5
b are divided and formed, and indoor air intake suction ducts 6 are formed on both sides of the main frame 1 where the indoor heat exchange chamber 2 is located. An indoor heat exchanger 7 as a cooler (evaporator) and an indoor blower 8 are installed in the indoor heat exchange chamber 2. The indoor blower 8
At the main frame body 1 where is located, a blowout port 9 for cool air is formed so as to blow cool air into the room. Further, each well-known refrigerant compressor 10 is installed in the machine room 3, and each outdoor heat exchanger 11 as a condenser and the outdoor blower 12 are provided in the outdoor heat exchange chamber 4, respectively. ing. Further, each of the main frame 1 in which the outdoor heat exchange chamber 4 is located is formed with each of the intake ports 13 for the outdoor air, and from each of the intake ports 13, the outdoor heat exchange chamber 4 is formed.
After the heat of the air flowing in to each of the outdoor heat exchangers 11 is exchanged,
It is exhausted to the outside by the outdoor blower 12.
On the other hand, in the upper opening of the main frame 1 in which the indoor heat exchange chamber 2 is located, as shown in FIGS. 2 and 3, a cover body 20 constituting a substantially rectangular falling dish-shaped indoor cover. The punching reinforcement covers 21 and 22 are attached to the inside and outside of the cover body 20 by welding. A mounting seat 20a is formed inside the lower part of the cover body 20, and a cut-and-raised reinforcing rib 20b is formed at an end of the mounting seat 20a.

On the other hand, a cover member 16 in the shape of a substantially rectangular falling dish is capped at the upper opening of the main frame 1 in which the machine room 3 is located, and the outdoor heat exchange is performed. A cover member 17 in the shape of a substantially square dish plate is capped and provided in the upper opening of the main frame 1 in which the chamber 4 is located.

Therefore, now, the punching reinforcement covers 2 are provided inside and outside the cover body 20 as the indoor cover.
Since Nos. 1 and 22 are attached, even if a load is applied to the entire cover 20 due to pressurization or depressurization due to change in atmospheric pressure, pressurization or depressurization due to atmospheric pressure change is applied to the entire cover and is uniformly dispersed. Therefore, there is no risk of cracks, and the heat insulating material can be easily attached to the inside of the punching reinforcing cover 22. Although the present invention has been described for the case where the punching reinforcement covers 21 and 22 are attached to the inside and outside of the cover body 20 that constitutes the interior cover, for example, within the range not changing the gist of the present invention, The design can be freely changed to be applied to the cover member 16 of the machine room 3 or the cover member 17 of the outdoor heat exchange chamber 4. Further, according to the present invention, it goes without saying that the punching reinforcing cover 22 may be attached only to the inside of the cover body 20.
