Abstract

PURPOSE: To promote reliability of air amount adjustment blown from blower, by providing air venting fan and annular damper with slots on its periphery, and by adjusting overlapped area of the slots of damper with respect to air vent outlet of the fan.
CONSTITUTION: When fan 2 is rotated by motor 3, air sucked from its suction opening 5 is discharged through vent outlets 6a, 6b of fan case 1. Disposed slidably along inner periphery of case 1 is annular damper 7 consisting of three arc-like damper sections 7a, 7b, 7c, and having two slots 9a, 9b which can be respectively aligned with vent outlets 6a, 6b. Both ends of section 7c are pivotally connected respectively to section 7a and 7b by arbors 8 with rotatable rollers 11 and spring plates 12 by which sections 7a and 7b are biased so as to be kept in contact with inner periphery of case 1. Sections 7a and 7b are not directly connected, and free ends thereof are spaced apart from each other. Thus, if damper 7 is turned along inner periphery of case 1, overlapped are as between vent outlets 6a, 6b and slots 9a, 9b can be adjusted as will, so as to regulate air amount passing therethrough at any desired value.
