Abstract

There is provided an electric blower capable of satisfactorily enhancing the blowing efficiency of an impeller and an electric cleaner having the electric blower. In the electric blower of the present invention, an area of a passage cross-section perpendicular to a center line of a passage, defined by front shroud 2, rear shroud 3 and hub 6 of inducer 8 from inlet 5 to outlet 25 of impeller 1, is monotonically increased from inlet 5 to outlet 25. Accordingly, air flow speed depending on the flow rate in impeller 1 is gradually decreased throughout the whole passage from inlet 5 to outlet 25, so that acceleration or rapid deceleration of the air flow speed is prevented, thereby satisfactorily enhancing the blowing efficiency.
