Abstract

PURPOSE: To decrease noise from ventilating fan, by avoiding unfavorable influence from the motor supporting structure and installing the damper apart from the fan, as well as by positioning the motor on the upper side of the fan and supporting it from the ceiling board, and providing large space with the silencer.
CONSTITUTION: With the motor 3 supported by the ceiling board 2a of the fan housing 2 and positioned on the upper side of the fan 4, enough large space can be available for the silencer 5 on the exhaust side. Noise from the fan can be decreased because of the absence of any obstacle such as the damper prop or the motor support either on the upper or the lower side of the fan 4. With the sucking passage 7 made of ringed lining duct, sufficient sucking space can be secured even though the width S of the passage is narrow, as well as the secondary air noise due to increasing speed of wind flow or damage from air pressure can be prevented. The noise from the fan can also be decreased, because the damper 10 is installed apart from the fan 4 in order not to disturb the flow of sucking air.
