According to what is disclosed in Japanese Patent No. 8661, an intake port and an exhaust port are provided in a housing of an indoor unit through a ventilation path, and a heat exchanger is arranged substantially vertically on the intake port side, while the heat exchange is performed. In an air conditioner in which an indoor fan is installed in the ventilation path on the lower side of the heat exchanger, a plurality of straightening vanes of approximately the same width as the width of the heat exchanger but different in length are provided at predetermined intervals in the vertical direction of the heat exchanger. The airflow distribution of the heat exchanger is made uniform by reducing the noise and the air conditioning capacity by setting each of the straightening vanes at the same angle in the intake flow path from the rear side of the heat exchanger to the indoor fan. We are trying to improve

音もかなり増加する。The indoor unit for an air conditioner is often installed by embedding it in the ceiling or hanging it from the ceiling. However, recent buildings have low ceilings and There is little space. Therefore, further miniaturization of the indoor unit for an air conditioner has become an important issue. Especially for the type that is embedded in the ceiling, the area that can be installed is limited because it is installed between the beams on the ceiling, and the number of buildings with a lower ceiling height increases, resulting in smaller and thinner structures. Is mandatory. In order to make the indoor unit for an air conditioner smaller and thinner, it is essential to make the heat exchanger smaller, but simply reducing the size of the heat exchanger will satisfy the performance of the air conditioner. Is not possible and the noise is considerably increased.

機の小型化には貢献しない。In order to reduce the size of the heat exchanger while ensuring the performance as an air conditioner, it is necessary to improve the performance of the heat exchanger. There is a means to make the shape of the fin a new shape to improve the performance of the heat exchanger, but it is more effective to make the wind speed distribution of the heat exchanger uniform to improve the performance because noise can be reduced. . Even in the past, attention has been paid to this point, and the uneven wind speed distribution of the heat exchanger that occurs due to the blower characteristics of the indoor unit, and the wind speed distribution of the heat exchanger is uniform by installing a straightening plate in the heat exchanger on the suction side of the blower. It has been devised that the heat exchanger is installed in such a way that the shape of the heat exchanger is inclined according to the direction of the wind speed of the blower outlet, or that the blower outlet is inclined toward the center of the heat exchanger. However, the rectifying plate has a heat exchanger on the upstream side of the blower, and the method of inclining the heat exchanger is costly due to development of the production line, etc., and even if the indoor unit becomes thin, The footprint cannot be reduced. Also, even if the blower outlet is tilted, the position of maximum wind speed will change, and this will not be a fundamental improvement. On the other hand, there is also a low-cost control plate that positively guides the swirling flow of the blower to the heat exchanger as a noise reduction means, but it does not lead to uniform wind speed distribution of the heat exchanger, and it does not contribute to downsizing the indoor unit. Do not contribute.

い。In the case of suppressing the wind noise by pressing the heat exchanger, the wind speed distribution is made uniform because it is provided on the upper and lower front surfaces of the heat exchanger and does not control only the swirling flow of the water receiver. That is not enough consideration.

In view of the characteristics of the centrifugal blower 102, the wind velocity distribution of No. 2 is high on the top plate 110 side, and decreases toward the water receiver 106 side. Since the four sides of the heat exchanger 105 and the water receiver 106 are in contact with or close to each other, almost no air flows into the heat exchanger 105 up to this portion. By increasing the wind speed on the side of the water receiver 106 without changing the wind speed on the side of the top plate 110 to make the wind speed distribution of the heat exchanger 105 more uniform, the air conditioning capacity is reliably improved, and as a result, noise can be reduced. On the other hand, the air flow of the indoor unit for an air conditioner includes not only a flow in the vertical cross section direction but also a flow in the horizontal cross section direction, that is, a swirling flow (circumferential flow). In particular, on the side of the water receiver 106, the swirling flow is dominant due to the characteristics of the centrifugal blower 102. This swirling flow is applied to the heat exchanger 10
5 to make the wind speed distribution of the heat exchanger 105 more uniform, the air conditioning capacity is similarly improved, and as a result, noise can be reduced. In the present embodiment, the swirling flow on the side of the water receiver 106 is made to pass more through the heat exchanger 105 so as to be more uniform and improve the air conditioning capacity.
