Multi-cyclone dust collector for vacuum cleaner and vacuum cleaner employing the same
First Claim
1. A multi-cyclone dust collector for a vacuum cleaner, comprising:
- a first cyclone unit causing dust-laden air sucked into 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, the second cyclone unit causing partially clean air, which is discharged from the first cyclone unit and then enters into a lower portion of the second cyclone unit, to form a second upwardly whirling air current so as to separate fine contaminants from the partially clean air by centrifugal force.

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.

13. A vacuum cleaner comprising:
-
a vacuum generator generating suction force;
a suction brush sucking dust-laden air by the suction force;
a multi-cyclone dust collector separating and collecting contaminants from the air sucked through the suction brush;
wherein the multi-cyclone dust collector comprises;
a first cyclone unit in fluid communication with the suction brush at a lower portion of the first cyclone unit, the first cyclone unit causing the dust-laden air 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, the second cyclone unit causing partially clean air, which is discharged from the first cyclone unit and then sucked into a lower portion of the second cyclone unit, to form a second upwardly whirling air current so as to separate fine contaminants from the partially clean air by centrifugal force. - View Dependent Claims (14)
