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