Abstract
Provided is an air blower for an air conditioner. The air blower for the air conditioner includes a centrifugal fan and a fan housing. The fan housing covers the centrifugal fan, and forms a scroll-type flow path having a varying cross-sectional area and guiding air forcibly blown by the centrifugal fan to an outlet. Here, a bottom surface of the scroll-type flow path inclines and is thinnest near a region where the scroll-type flow path ends. The thickness of the bottom surface progressively increases along a straight line running from a region where the bottom surface is thinnest to an opposite outer side of the scroll-type flow path through a center of the centrifugal fan.
