About the conventional air conditioner configured as above,
The operation will be described below. First, the wind flow of the multi-blade blower 2 flows in the direction of the arrow having an angle to the circumferential tangential direction to some extent from the radial direction of the multi-blade blower 2, and the flow is directed at right angles to the heat exchanger 1 by the straightening vanes 6. It is configured so that it is deflected so as to lead to.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention However, in the above configuration, when the heat exchanger 1 is vertically long, the distance between the heat exchanger 1 and the multiblade blower 2 is large (when the outer diameter of the multiblade blower is 0.2 or more). Does not have the effect of the straightening vane 6, but there is an effect of the arrangement of the straightening vane 6 in the place where the heat exchanger 1 and the multiblade blower 2 partially come close to each other. The distance between 1 and the multiblade blower 2 must be increased.

Therefore, the outer diameter of the multiblade blower 2 is reduced to increase the number of revolutions to secure the required air volume. As a result, there is a drawback that noise is increased due to an increase in the number of rotations. Further, since the straightening vanes 6 are arranged around the entire circumference of the multiblade blower 2, there is a drawback that workability is poor.

Action Since the air conditioner of the present invention has the above-mentioned configuration, the flow rectifying plate allows the air from the multi-blade blower to flow in a direction perpendicular to the portion of the heat exchanger that approaches the multi-blade blower,
Noise can be reduced by reducing wind turbulence. Further, since it is only necessary to dispose the current plate in the space where the multiblade blower and the heat exchanger are close to each other, the configuration is simple and the workability is also good.

Effects of the Invention As described above, the air conditioner of the present invention includes a multi-blade blower,
The multi-blade blower is provided with a heat exchanger arranged in close proximity to a part thereof, and a straightening vane arranged in a space where the multi-blade blower and the heat exchanger are close to each other. Since the wind from the multi-blade blower flows in a direction perpendicular to the portion approaching the blade blower, the flow of the wind blown from the multi-blade blower flows into the heat exchanger without disturbance. Also, ventilation resistance can be reduced and noise due to turbulence does not occur. Furthermore, the outer diameter of the multi-blade blower can be increased to reduce noise. Further, since it is not necessary to dispose the current plate around the entire circumference of the multiblade blower, workability can be improved and cost can be reduced.
