Abstract

PURPOSE:To utilize the site effectively, and improve the cooling effect by a method wherein the outdoor unit of an air conditioner is stored in an attic, and at the same time, the front surface of the outdoor unit is covered by a louver window. CONSTITUTION:For the title air conditioner, the air outlet of an outdoor unit 2 is arranged to face a ventilation port which is provided in an attic, and at the same time, the front surface of the outdoor unit 2 is covered by a louver window 4. When an exhaust fan 6 of the outdoor unit 2 is operated, air which is drawn from air intake ports 5 being formed on the front surface side and rear surface side is heat-exchanged by a heat-exchanger 7, and is discharged from an air outlet 3. When air is drawn from the air intake port 5 on the rear surface side, the air pressure of the attic reduces, and therefore, the outside air is drawn from the other ventilation port, and the ventilation of the attic is performed. For this reason, a site to install the outdoor unit 2 becomes unnecessary, and the land can be effectively utilized, and at the same time, the appearance of a building is not spoiled. Also, by the forcible ventilation of the attic, warmed air is emitted to the outside, and the temperature of the attic decreases, and therefore, the cooling effect is not spoiled.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner which is generally called a separate type and which is composed of an indoor unit and an outdoor unit.

[0002]

2. Description of the Related Art An outdoor unit 2a of a conventional air conditioner is shown in FIG.
As shown in, it was installed next to the building or in one corner of the balcony. Also, when the roof of a building is exposed to sunlight, the warmed air is trapped in the attic, so a ventilation port was provided in the attic for natural ventilation. Further, a louver window 4a was attached to the ventilation port to cover it so that rainwater would not enter.

[0003]

Since the outdoor unit 2a of the conventional air conditioner is installed beside a building or at one corner of the balcony, the outdoor unit 2a occupies a part of the site,
In addition to not being able to effectively utilize the site, the outdoor unit 2a is exposed to the outside of the building, which causes the appearance of the building to deteriorate.

[0004] In addition, in the case of natural ventilation in which only the ventilation opening is provided in the attic, the warmed air cannot be exhausted and stays in the attic, so that hot air comes down from the ceiling and the cooling effect is impaired even if it is cooled. There was also a problem. Therefore, an object of the present invention is to provide an air conditioner that solves the above-mentioned problems, can effectively utilize the site, and can enhance the cooling effect.

[0005]

In the present invention, the indoor unit 1
And an outdoor unit 2 in which the exhaust port 3 of the outdoor unit 2 is disposed so as to face a ventilation port provided in the attic, and the front face of the outdoor unit 2 is covered with a louver window 4. And, the above-mentioned subject was solved. The heat exchanger 7 of the outdoor unit 2 is preferably formed in a substantially U shape so as to surround the exhaust fan 6.

Further, it is preferable that the intake port 5 of the outdoor unit 2 is formed on the front side and the rear side of the outdoor unit 2, and the intake ports 5 on the front side and the rear side are connected by the ventilation passage 10. It is preferable to provide a shutter 11 that can be opened and closed at the intake port 5 on the back side. It is preferable that the blades 12 of the shutter 11 are tilted inward of the outdoor unit 2.

[0007]

In the present invention, since the outdoor unit 2 of the air conditioner is housed in the attic, the site required for installing the outdoor unit 2 becomes unnecessary. Furthermore, since the front surface of the outdoor unit 2 is covered with the louver window 4, the outdoor unit 2 cannot be seen from the outside of the building. When the air conditioner is used, the warm air trapped in the attic is discharged by the exhaust fan 6 of the outdoor unit 2, so that the temperature of the attic decreases.

Since the heat exchanger 7 of the outdoor unit 2 is formed in a substantially U shape so as to surround the exhaust fan 6, the length of the heat exchanger 7 can be increased, so that the same heat exchange effect can be obtained. However, the width of the heat exchanger 7 can be narrowed to the same width as the conventional louver window 4a. Further, the intake ports 5 of the outdoor unit 2 are formed on the front side and the rear side of the outdoor unit 2, and the intake ports 5 on the front side and the rear side are connected to the ventilation passage 1
By connecting with 0, even if an air conditioner is installed in the ventilation port, the ventilation port will not be blocked.

If a shutter 11 that can be opened and closed is provided at the intake port 5 on the back side, when ventilation of the attic is unnecessary in the winter and the like, the ventilation of the attic is maintained even if the shutter 12 is closed and the air conditioner is operated. You can prevent it. By tilting the blades 12 of the shutter 11 of the intake port 5 on the rear surface side toward the inside of the outdoor unit 2, even if water drops are attached to the blades 12 due to humidity, the blades 12 fall inside the outdoor unit 2.
