BLOWER DEVICE, METHOD FOR MANUFACTURING BLOWER DEVICE, AND INTEGRATED UNIT

摘要

PROBLEM TO BE SOLVED: To provide a blower device, a method for manufacturing the blower device, and an integrated unit enabling design keeping small the clearance between a bell-mouth and a propeller fan, and improving aerodynamic characteristics.;SOLUTION: This method for manufacturing the blower device 1 is the method for manufacturing the blower device 1 provided with a fan part 3 provided with the propeller fan 8 and a motor 9, the bell-mouth 4 covering a periphery of the propeller fan 8, and a body casing 2 having the fan part 3 and the bell-mouth 4 stored therein. The manufacturing method includes a resin forming process, a fixing process, and a cutting process. Resin is formed to be a state connecting the bell-mouth 4 and the propeller fan 8 with at least one connection part 10 by one forming die in the resin forming process. The propeller fan 8 is connected to a shaft 13 of a motor 9 and the bell-mouth is fixed on the body casing 2 under a condition where the bell-mouth 4 and the propeller fan 8 is connected by the connection part 10 in the fixing process. The connection part 10 is cut off and the bell-mouth 4 and the propeller fan 8 are separated in the cutting process.;COPYRIGHT: (C)2009,JPO&INPIT
