Multi-cyclone dust collector for vacuum cleaner and vacuum cleaner employing the same

US-7966692-B2

Abstract

The present invention relates to a multi-cyclone dust collector and a vacuum cleaner employing the same that forms an upwardly whirling air current so as to separate contaminants. The multi-cyclone dust collector for the vacuum cleaner includes a first cyclone unit causing dust-laden air sucked through a lower portion of the first cyclone unit to form a first upwardly whirling air current so as to separate contaminants from the dust-laden air by centrifugal force, and a second cyclone unit disposed under the first cyclone unit and making partially clean air, which is discharged from the first cyclone unit and then sucked in a lower portion of the second cyclone unit, to form a second upwardly whirling air current so as to separate dust from the partially clean air by centrifugal force.
