BLOWER FOR VEHICLES

摘要

A vehicle blower device is provided to introduce inside air into a vehicle room even in the case of an outside air mode by an inside air introducing unit mounted to a scroll case in a simple structure, thereby improving heating performance. A vehicle blower device includes an inside air introducing unit(140) formed with an inside air inlet path(121a) formed at a side of an upper end of a scroll case(120). An auxiliary door(135) is coupled with an outlet portion of the inside air inlet path by coupling elements(150) for opening the path in response to rotation of a blower fan(123). The outlet portion and the auxiliary door are inclined for increasing an area for introducing inside air. The coupling elements are a plurality of protrusions(151) formed at an upper end of the outlet portion and a fixing element(152) for fixing the auxiliary door to the protrusions.
