[0004]

In order to achieve the above-mentioned object, an indoor heat exchanger and an indoor heat exchanger are arranged in a housing so as to face each other, and air from a suction port is blown through the indoor heat exchanger. In an air conditioner including a blower that blows air to an outlet, the indoor heat exchanger is bent into a substantially L shape, and a second suction port is formed on a side surface of the housing facing the bent portion.
It is characterized in that an outside air intake duct is connected to the second suction port. Further, the tip of the bent portion is extended to the blower. In addition, the bending angle of the bent portion is such that the width between the second suction port and the length between the side surface of the housing forming the second suction port and the end of the blower are two sides. It is characterized in that it is formed in substantially the same angle as the diagonal of the rectangle. The tip of the bent portion is extended to the end of the second suction port on the blower side. Further, a plurality of slits and a connecting portion are formed between the slits on one side surface of the housing, and the connecting portion is cut to serve as the second suction port. The slit is formed into a substantially circular shape.

[0005]

According to the above structure, the indoor heat exchanger and the blower that is arranged so as to face the indoor heat exchanger and blows the air from the suction port through the indoor heat exchanger to the air outlet are provided. In the equipped air conditioner, the indoor heat exchanger is approximately L
A bent shape is formed, a second suction port is formed on the side surface of the housing facing the bent portion, an outside air intake duct is connected to the second suction port, and the tip of the bent portion is , Extending to the blower, the bending angle of the bent portion, the width of the second suction port, between the side surface of the housing forming the second suction port and the end of the blower. Form the angle of the diagonal of a rectangle with two sides, and
The tip of the bent portion is extended to the end of the second suction port on the blower side. Further, on one side surface of the housing, a plurality of slits and a connecting portion are formed between them, and the connecting portion is cut to serve as the second suction port, and the shape of the slit is substantially circular. Since it is configured to have a shape, the installation work of the indoor unit body can be simplified, the depth dimension of the body can be shortened, and as a result, the size can be reduced.

[0006]

Embodiments of the present invention will be described in detail with reference to the accompanying drawings. The same parts as those in the conventional example are denoted by the same reference numerals. FIG. 1 is a cross-sectional view of an air conditioner showing an embodiment of the present invention. An air conditioner is configured by an indoor heat exchanger 2 inside the housing 1 and a blower 3 that is arranged so as to face the indoor heat exchanger and blows air from the suction port 1a through the indoor heat exchanger to the air outlet 6 To do. Here, the indoor heat exchanger is bent into a substantially L shape, and the second suction port 1b is formed on the side surface of the housing facing the bent portion 2a. Further, the outside air intake duct 5 is connected to the second suction port. Then, the tip of the bent portion is extended to the blower 3.

The bending angle of the bent portion 2a is
As shown in FIG. 2, a rectangle W having a width W of the second suction port and a length D between the side surface of the housing forming the second suction port and the end of the blower as two sides. The angle is almost the same. Then, the tip of the bent portion 2a is extended to the end of the second suction port on the blower side. Further, FIG.
As shown in FIG. 5, a plurality of slits 1c and a connecting portion 1d are formed on one side surface of the housing 1, and the connecting portions are cut to serve as the second suction port.
Then, the slit is formed into a substantially circular shape.
Therefore, the duct installation work is simplified. Also, the depth dimension of the main body can be reduced.

[0008]

As described above, according to the present invention, the indoor heat exchanger and the indoor heat exchanger are arranged in the casing so as to face each other, and the air from the suction port is blown to the air outlet through the indoor heat exchanger. In the air conditioner provided with a blower, the indoor heat exchanger is bent into a substantially L shape, and a second suction port is formed on a side surface of the housing facing the bent portion. An outside air intake duct is connected to the suction port, the tip of the bent portion is extended to the blower, and the bending angle of the bent portion is the same as the width of the second suction port. (2) The length between the side surface of the housing that forms the suction port and the end of the blower is formed to be substantially the same as the angle of the diagonal line of the rectangle having two sides, and the tip of the bent portion is (2) Stretch to the end of the suction port on the blower side.

Furthermore, a plurality of slits and a connecting portion are formed between the slits on one side surface of the housing, and the connecting portion is cut to form the second suction port, and
Since the shape of the slit is formed in a substantially circular shape, the installation work of the indoor unit body can be simplified and the depth dimension of the body can be shortened, and as a result, the apparatus body can be downsized. Can be done.
