PURPOSE:To optionally and surely set the direction of air blow-off, by rotatably supporting a deflecting plate at a nozzle-like air blow-off port and providing a deflector interlocked with the deflecting plate so that the are-shaped inlet and outlet parts of the deflector can be brought into and out of contact with each other. CONSTITUTION:When a lever 22 is set downward, the deflecting plate 20 is also set downward and a step portion 24' of the inlet part 24 and the outlet part 25 come into contact with each other. Then, the air from a blower 12 is oriented downward by the deflecting plate 20, and the air passing through the deflector 23 flows from the inlet part 24 along the outlet part 25 and is oriented downward further due to the Coanda effect produced by the step portion 24'. When the lever 22 is set horizontal, the deflecting plate 20 is set upward and the inlet part 24 is separated from the outlet part 25. Thus, the downward air on an oblique part 7 and the upward air on the upper side of the deflecting plate 20 flow horizontally because of their mutual attraction. The air over the deflector 23 is affected only by the inlet part 24, so that the and flows almost horizontally. Therefore, the direction of the blow-off can be efficiently determined. |
