Patent number: 9513021Abstract: The rear side outer peripheral edge of a propeller fan rotated and driven by a motor, of a propeller fan drive unit, is surrounded by a bell mouth. An upper plate, a lower plate, a side plate, and a machine room plate constitute an air duct at the suction side, outside the radial direction of the propeller fan. The cross-section of the bell mouth, at a first position in the vicinity where a blade of the propeller fan is closest, and where the distance between the propeller fan and the plate constituting the air duct outside the radial direction is relatively narrow, is made to be such that an expansion angle ?1 of the bell mouth suction side is made small. The overlapped height Hb of the propeller fan and the bell mouth is made large against a cross-section at a second position where the distance between the propeller fan and a plate is relatively large. The shape of the cross-section of the bell mouth is made to change gradually between the first position and the second position.Type: GrantFiled: October 29, 2009Date of Patent: December 6, 2016Assignee: MITSUBISHI ELECTRIC CORPORATIONInventors: Yasuaki Kato, Takahide Tadokoro, Masanobu Baba, Hiroyuki Takada
