Abstract

PURPOSE: To prevent noise by a method wherein an airflow regulating plate fitted with a movable suction port is arranged on the opposite side of a fan relative to a fixed suction port in such a manner that it can freely slide in the axial direction of a motor, and an airflow is introduced either from the movable suction port alone or from both the movable suction port and the clearance between the regulating plate and the fixed suction port.
CONSTITUTION: With an airflow regulating plate 8 contacted with a fixed suction port 5, the air flows in only from an opening hole 9 so that the amount of airflow is minimum. With the airflow regulating plate 8 gradually parted away from the fixed suction port 5, the clearance 15 is enlarged and the amount of air flowing is increased, the maximum airflow being attained when the clearance 15 is maximum. The regulating plate 8 is adjusted by operating a knob 11. Accordingly, since any small passage is not formed at the time of airflow regulation, greater noise is avoided and failure of regulation due to missing of parts is avoided.
