Abstract
PURPOSE: To promote the efficiency of a fan by shaping an impeller to have a smooth expansion near the exit upward and/or downward in the direction of the height of a blade for removing the loss caused by the sudden expansion of an air stream.
CONSTITUTION: An impeller 4' is shaped near its exit part 18 to keep some expansion with a smoothly curved surface in its height direction. As a motor is rotated, air is conducted to an air guide through the inside of the impeller 4'. Although there is a difference between the exit height B2 of the impeller and the air guide height B3 near the exit part 18 of the impeller, the smooth expansion at the exit part 18 removes the loss caused by the sudden expansion of an air stream, and promotes the efficiency of a fan.
