Abstract
A multi dust-collecting apparatus for a vacuum cleaner separating dirt particles from air by taking two steps. The multi dust-collecting apparatus includes a dust-collecting unit to separate dirt particles from the air by using gravity and inertia, and a plurality of cyclones to swirl the air discharged from the dust-collecting unit and separate the dirt particles from the air by using centrifugal force.
Claims11
A multi dust-collecting apparatus comprising:
- a first dust-collector to separate dirt particles from drawn-in air by using a gravity and an inertia;
- a second dust-collector arranged along a circumference of the first dust-collector to separate minute dirt particles from the air flowing from the first dust-collector using a centrifugal force;
- a cover unit disposed above the first and the second dust-collectors to guide the air discharged from the first dust-collector towards the second dust-collector and to discharge the air discharged from the second dust-collector to the outside;
- and
- a dirt receptacle unit to collect the dirt particles separated from the air in the first and the second dust-collectors.
