Abstract
PURPOSE: To reduce the air turbulence in the proximity of the discharge port by forming a discharge passage adjecent to the discharge port with it depth in the dimension about same as the width of an impeller.
CONSTITUTION: When a drive shaft 4 is rotated, impeller 13 also rotates in the direction of an arrow 21, and the air sucked from a suction port 16 is gradually pressurized between the blades 14 of the impeller 13 and reaches a discharge port 17. When the depth of a discharge passage 19 is made to be approximately same dimension as the width of the impeller 13, all the high pressure air leating from an air passage 12 to the discharge passage 19 flows straight to the direction of the discharge passage 19 where it is sufficiently straightened and discharged to outside through the discharge port 17 thereby providing an efficient action of fan without a loss by turbulence.
