Cyclone dust collecting apparatus and vacuum cleaner having the same

摘要

A cyclone dust collecting apparatus for a vacuum cleaner includes a first chamber (10); an entering passage (55) disposed above the first chamber, the entering passage guiding outer air to form a downwardly whirling air current in the first chamber (10); a second chamber (40) formed at a position higher than that of an outlet of the entering passage above the first chamber, the second chamber (40) in which the outer air entering from the first chamber (10) whirls; a contaminants-blocking member (60) disposed to be spaced apart from a bottom surface of the first chamber at a center of the first chamber, the contaminants-blocking member (60) preventing contaminants and water separated in the first chamber (10) from moving into the second chamber (40); and a grill (70) disposed inside the second chamber to be in fluid communication with an air discharging port (29) through which clean air is discharged.
