Abstract:
PURPOSE: To enhance the blowing efficiency of a blower, by forming a rotary blade in an arcuated cross-sectioned shape which is symmetrical on the inlet and outlet sides, and making guide vanes attached on the inlet and outlet sides, adjustable in their attaching angles.
CONSTITUTION: The cross-sectioned shape of a rotary blade is formed such that it is symmetric with each other on the air inlet and outlet sides. A plurality of guide vanes 7A, 7B are attached to the inner surface of a cylindrical casing 1 at the inlet and outlet sides of the rotary blade 6, and are adjustable in their attaching angles. Accordingly, no substantial difference is appreciated in blowing efficiency between both blowing directions of air.
