Cyclone dust-collecting apparatus

摘要

A cyclone dust-collecting apparatus comprises: a cyclone body having a suction passage formed therein; an upper cover disposed on an upper portion of the cyclone body; a dirt receptacle disposed under the cyclone body; and a noise-reducing member nested in the cyclone body in contact with an inner surface of the cyclone body, wherein dust-laden air flowing through the suction passage collides with the noise-reducing member so that a noise can be reduced.
