Cyclone dust collecting apparatus and vacuum cleaner having the same
First Claim
1. A cyclone dust collecting apparatus for a vacuum cleaner comprising:
- 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 at a center of the first chamber and spaced apart from a bottom surface of the first chamber to prevent 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,wherein the entering passage is formed in a helical pipe shape wound at least one turn along the first chamber, andwherein the outlet of the entering passage is formed at a position that is lower than that of an inlet of the entering passage and that is the same as or lower than that of the contaminants-blocking member.
