Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner, and more particularly to a wall-mounted or ceiling-hung air conditioner.

[0002]

2. Description of the Related Art A home air conditioner is preferably one in which the main body does not project to the indoor side as much as possible when installed indoors.
Separation type air conditioners, which have become the mainstream of home air conditioners, have outdoor units that are placed outdoors, and the size of indoor units is minimized. The mainstream of these separation type air conditioners is a wall-mounted type, and the side face has a thin and vertically long form in which the front and rear length is smaller than the height so that the main body cabinet does not protrude as much as possible. However, various demands have become apparent as the spread of the separation type air conditioner has improved. One of them is a demand for a wall-mounted air conditioner with a small mounting space.

In order to reduce the mounting space on the wall surface, conventionally, as shown in FIG. 10, the main body cabinet has a thin shape whose height is shorter than the front-rear length, and the air suction port is on the front face and the air discharge port is on the front side. An air conditioner has been proposed in which the outlets are respectively arranged at the rear of the bottom surface and the upper surface of the main body cabinet is mounted on the wall surface so as to be positioned substantially parallel to the ceiling surface. These conventional examples are, for example, actual Kaihei 2-30.

[0004]

In the conventional example shown in FIG. 10 (a), since the side face shape is a rectangular parallelepiped main body cabinet 1, a main body cabinet having a large air suction port in the front part is used. It was overhanging to the inside of the room, giving the user a feeling of pressure.

Further, in the conventional example shown in FIG. 10 (b), by making the side shape "horizontal L-shaped", the front portion of the main body cabinet is thinned to reduce the feeling of oppression. However, in this conventional example, since the step portion is formed on the bottom surface portion,
Not only does it not match the interior of the room, but the air inlet provided in the front part becomes smaller, and the opening ratio of the air inlet is reduced.

Further, in both of the conventional examples, since the wind direction plate in the air discharge port is formed in the shape of a horizontal bar and the air discharge port is arranged on the horizontal plane, it is difficult to blow the cool air further forward. In addition, the air outlet was always open and did not match the interior of the room.

The present invention has been made to solve the above-mentioned problems, and an object thereof is to excellently blow cold and warm air,
It is to provide a thin air conditioner with less pressure.

An air outlet provided on the back side, the top surface of the main body cabinet is a plane substantially parallel to the ceiling surface, and the bottom surface part of the main body cabinet goes from the back side to the front side. Follow the instructions to go up.

Further, as a preferable one, a thin main body cabinet in which the front-rear length of the upper surface portion is larger than the height of the rear surface portion of the main body cabinet is used.

Further, it is preferable that the bottom surface is an arc surface or a flat surface.

Further, as a preferred one, a movable wind direction plate capable of concealing the air discharge port when not in use is provided.

Further, as a preferable example, the front portion of the main body cabinet is inclined rearward.

[0013]

[Operation] By raising the bottom surface of the main body cabinet from the rear side to the front side,
The pressure on the body cabinet is reduced. Further, by providing the air outlet on the inclined bottom surface portion, the air outlet can be directed forward. In addition, by providing the air suction port on the upper surface, while hiding the air suction port,
A large aperture ratio can be obtained.

Further, by providing the air discharge port with a movable wind direction plate capable of concealing the air discharge port, it is possible to make the entire bottom surface part a uniform convex surface or a flat surface when not in use.

Further, by tilting the front portion rearward, the main body cabinet can be made thin and the air intake port of the front portion can be made small.
