Beschreibung
Zusammenfassung:	A sirocco fan is provided that may include an impeller, in which a plurality of first blades and a plurality of second blades are formed on a main plate, and a scroll housing that covers the impeller. The scroll housing may include air suction holes formed on both of first and second plates and a rounded portion formed to be convex in an opposite direction of the impeller on a scroll that connects both of the first and second plates. An interval from the main plate to the rounded portion in a direction perpendicular to a rotation central axis of the impeller may be the largest. A rapid change in direction of air flowing to the scroll from the impeller may be minimized, and collision of air with the scroll may be lessened, reducing a flow loss and enhancing efficiency.
