DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioner provided with a cross flow fan as a blowing means,
The present invention relates to measures for improving the shape and layout of a heat exchanger for adjusting the temperature of air taken in from a cross flow fan.

[0002]

2. Description of the Related Art Conventionally, for example, Japanese Patent Publication No. 7-5201
As disclosed in Japanese Unexamined Patent Application Publication No. 6-62, there is known an indoor unit of an air conditioner that blows air with a cross flow fan. As shown in FIG. 9, this type of indoor unit has an air suction port (b) at the upper part of the front of the casing (a).
An air outlet (c) is provided at the lower part of the front of (a). And, in the casing (a), the air inlet (b)
A heat exchanger (d) is arranged upright facing the air conditioner, and a cross flow fan (e) is arranged at the back of the heat exchanger (d) (downstream in the air flow direction). . Further, an air flow guide (f) is provided between the cross flow fan (e) and the air outlet (c). This air flow guide (f)
A circular arc-shaped portion (h) bulging in an arc along the crossflow fan (e) with a radius of curvature larger than the outer periphery of the crossflow fan (e), and an upstream end of the arc-shaped portion (h). And a suction port (g) formed to communicate with the air outlet (c),
The air flow sucked from the suction port (g) by the operation of the cross flow fan (e) is guided straight to the air outlet (c).

[0003] The indoor air introduced into the casing (a) from the air suction port (b) with the driving of the cross flow fan (e) flows between the refrigerant flowing through the refrigerant pipe of the heat exchanger (d). After adjusting the temperature by performing heat exchange, the air is sucked into the air flow guide section (f) from the cross flow fan (e), and blown out as air-conditioned air from the air outlet (c) toward the room. .

[0004]

Incidentally, in the above cross flow fan (e), a substantially semicircular portion from the suction port (g) is exposed downstream of the heat exchanger (d) in the air flow direction. Air is drawn in over a wide area from almost the entire exposed part.

In this case, air flows from the air inlet (b) through the heat exchanger (d) and is sucked into the cross flow fan (e), so that the cross flow fan (e) can be used efficiently. Also in this case, it is necessary to reduce the flow resistance of the air flowing through the heat exchanger (d).

However, in the above-mentioned conventional indoor unit, since the heat exchanger (d) is arranged to face the air suction port (b), the opening area of the air suction port (b) and the heat exchanger (d) are different. ) Almost coincides with each other, and only the same amount of air can flow through the heat exchanger through the air inlet. Therefore, when the cross flow fan (e) operates, the flow resistance of the air passing through the heat exchanger (d) increases, and the cross flow fan (e)
However, there is a disadvantage that the blowing efficiency is deteriorated due to the airflow.

Further, when the heat exchanger (d) is erected inside the casing (a), the casing itself becomes very bulky, and the heat exchanger is arranged compactly in order to make the indoor unit compact. There are also requests to do so.

[0008] The present invention has been made in view of such a point, and an object of the present invention is to provide a heat exchanger so as to surround the cross flow fan, thereby reducing the air flow resistance to the heat exchanger. In this way, the blowing efficiency of the cross flow fan is improved, and the heat exchanger is arranged compactly.
