Multi-cyclone dust collector for vacuum cleaner and dust collecting method
First Claim
1. A multi-cyclone dust collector for a vacuum cleaner, comprising:
- a first cyclone unit comprising a first cyclone body, and a first dust collecting chamber, the first cyclone body taking dust-laden air entering through an under portion of the first cyclone body and forming a first upwardly whirling air current so as to centrifugally separate contaminants from the dust-laden air, the first dust collecting chamber collecting contaminants discharged from the first cyclone body; and
a second cyclone unit wrapping around at least a portion of the first dust collecting chamber, the second cyclone unit sucking semi-clean air discharged from the first cyclone unit through an under portion of the second cyclone unit, the second cyclone unit taking the semi-clean air and forming a second upwardly whirling air current so as to centrifugally separate fine contaminants from the semi-clean air.

Abstract
The present invention relates to a multi-cyclone dust collector for a vacuum cleaner and dust collecting chamber. The multi-cyclone dust collector includes a first cyclone unit having a first cyclone body and a first dust collecting chamber, the first cyclone body taking dust-laden air entering through an under portion thereof and forming a first upwardly whirling air current so as to separate contaminants centrifugally from the dust-laden air, the first dust collecting chamber collecting contaminants discharged from the first cyclone body; and a second cyclone unit wrapping around at least a portion of the first dust collecting chamber, sucking semi-clean air discharged from the first cyclone unit through an under portion thereof, taking the sucked semi-clean air and forming a second upwardly whirling air current so as to separate contaminants centrifugally from the semi-clean air.

14. A multi-cyclone dust collector for a vacuum cleaner comprising:
-
a first cyclone unit comprising at least one first cyclone body that separates contaminants from dust-laden air; and
a second cyclone unit separating fine contaminants from semi-clean air discharged from the first cyclone unit, the second cyclone unit comprising a plurality of second cyclones that is separate from the first cyclone body and wraps around at least a portion of the first cyclone body;
wherein the first and second cyclone units have bottom portions on the same horizontal surface. - View Dependent Claims (15, 16)

17. A dust collecting method comprising steps of:
-
entering dust-laden air into a bottom portion of at least one first cyclone;
whirling the dust-laden air upwardly to separate contaminants from the dust-laden air to form semi-clean air;
discharging the contaminants out of the at least one first cyclone;
discharging semi-clean air to the bottom portion of the at least one first cyclone through an air communicating member disposed inside the at least one first cyclone;
entering the semi-clean air into a plurality of second cyclones through second air suction ports formed on bottom portions of sides of the plurality of second cyclones, whirling the semi-clean air upwardly to separate fine contaminants from the semi-clean air to form clean air; and
discharging the clean air to the bottom portions of the plurality of second cyclones. - View Dependent Claims (18, 19)
