Abstract

See full text

An impeller includes a hub and a plurality of blades. The blades are disposed around an outer periphery of the hub. Each of the blades includes a connecting end, a sweep-back part and a sweep-forward part. The connecting end is coupled with the hub. The sweep-back part is disposed at an edge of the blade and extended from the connecting end. An extending direction of the sweep-back part is opposed to a rotating direction of the impeller. The sweep-forward part is extended from the sweep-back part. An extending direction of the sweep-forward part is the same as the rotating direction of the impeller.
