Abstract

PURPOSE: To increase the ventilating volume and to improve the efficiency of ventilation by making the diameter of intake opening equal to the external diameter of a fan right after the top of a turning point of casing pressure; and by making the diameter equal to the internal diameter of the fan in another areas.
CONSTITUTION: The intake opening 7 is formed in an egg-type shape by making the diameter of the intake opening 7 equal to the external diameter DO of the fan 2 within the area of suction immediately after the top of a turning point of casing pressure and making the diameter equal to the internal diameter DI of the fan 2 in another areas. Therefore, the suction area is not produced within the casing 7 because of the opening for intake containing the suction area immediately after the tip 9, and the air is smoothly sent out of the outlet 8. For this reason, the ventilating volume becomes greater, and the noise can be reduced because the average intake speed of air is lowered.
