Abstract
A multi-cyclone dust collector including at least one first cyclone forcing contaminants-laden air that is entered into a lower portion of the at least one first cyclone to whirl so as to centrifugally separate contaminants from the contaminants-laden air; and at least one second cyclone being disposed around the at least one first cyclone, the at least one second cyclone forcing semi-clean air that is discharged from the at least one first cyclone and is entered into a lower portion of the at least one second cyclone to whirl so as to centrifugally separate fine contaminants from the air.
Claims44
A multi-cyclone dust collector for a vacuum cleaner comprising:
- at least one first cyclone having a lower portion, the at least one first cyclone forcing contaminants-laden air that enters the lower portion to whirl so as to centrifugally separate contaminants from the contaminants-laden air, the at least one first cyclone discharging semi-clean air;
- and
- at least one second cyclone being disposed around the at least one first cyclone, the at least one second cyclone having a second lower portion, the at least one second cyclone forcing the semi-clean air that enters into the second lower portion to whirl so as to centrifugally separate fine contaminants from the semi-clean air, the at least one second cyclone discharging clean air.
A multi-cyclone dust collector for a vacuum cleaner, comprising:
- a first cyclone sucking contaminants-laden air into a lower portion of the first cyclone, the first cyclone forcing the contaminants-laden air to form a first upwardly whirling air current so as to centrifugally separate the contaminants from the contaminants-laden air;
- a first dust collecting chamber being disposed to wrap around at least a portion of the first cyclone, the first dust collecting chamber collecting the contaminants discharged from the first cyclone;
- and
- a plurality of second cyclones being disposed around the first cyclone, the plurality of second cyclones sucking semi-clean air that is discharged from the first cyclone into a lower portion of each of the second cyclones, the plurality of second cyclones forcing the semi-clean air to form a second upwardly whirling air current so as to centrifugally separate fine contaminants from the semi-clean air.

A multi-cyclone dust collector for a vacuum cleaner, comprising:
- at least one first cyclone sucking contaminants-laden air so as to separate contaminants, a first dust collecting chamber collecting the contaminants separated by the at least one first cyclone, at least one second cyclone re-separating centrifugally semi-clean air discharged from the at least one first cyclone, and a second dust collecting chamber collecting fine contaminants separated by the at least one second cyclone,

A method of collecting contaminants for a multi-cyclone dust collector, comprising:
- sucking contaminants-laden air into a lower portion of a first cyclone so as to form the contaminants-laden air into a first upwardly whirling air current inside the first cyclone;
- separating contaminants from the contaminants-laden air by centrifugal force so as to discharge the contaminants from the first cyclone in a direction opposite to the gravity direction;
- discharging semi-clean air from the first cyclone in the gravity direction;
- sucking the semi-clean air into a second lower portion of a second cyclone so as to form the semi-clean air into a second upwardly whirling air current inside the second cyclone;
- separating fine contaminants from the air by centrifugal force so as to discharge the fine contaminants from the second cyclone in a direction opposite to the gravity direction;
- and
- discharging clean air from the second cyclone in the gravity direction.
