Multi cyclone dust-collecting apparatus
First Claim
1. A multi cyclone dust-collecting apparatus, comprising:
- a dust-collecting housing that has a suction pipe formed on a bottom thereof and protruding to a predetermined length to allow an ambient air to be drawn in through the suction pipe, the dust-collecting housing for collecting dirt particles separated out from the drawn-in air;
a first cyclone that is disposed in the dust-collecting housing and has a first inlet port formed on a lower portion thereof to fluidly communicate with the suction pipe, the first cyclone for guiding the air drawn in through the first inlet port and then centrifugally separating out the dirt particles;
a plurality of secondary cyclones that are arranged outside the first cyclone at a predetermined interval and disposed in the dust-collecting housing, the plurality of secondary cyclones for centrifugally separating out fine dirt particles from the air discharged from the first cyclone; and
a cover unit that is disposed above the dust-collecting housing, the cover unit for guiding the air discharged from the first cyclone to the plurality of secondary cyclones, filtering again the air separated out from the dirt particles in the secondary cyclones, and discharging cleaned air outwardly.

Abstract
A multi cyclone dust-collecting apparatus including a dust-collecting housing; a first cyclone; a plurality of secondary cyclones; and a cover unit is provided. The dust-collecting housing has a suction pipe, which draws in ambient air. The first cyclone is disposed in the dust-collecting housing and has a first inlet port formed on a lower portion thereof to fluidly communicate with the suction pipe. The first inlet port and an air outlet port of the first cyclone have the same axis. The plurality of secondary cyclones are arranged outside the first cyclone at a predetermined interval and disposed in the dust-collecting housing. The cover unit guides the air discharged from the first cyclone to the respective secondary cyclones, filters again the air separated out from the dirt particles in the secondary cyclones, and discharges cleaned air outwardly.

17. A multi cyclone dust-collecting apparatus comprising:
-
a dust-collecting housing to collect dirt particles separated out from drawn-in air;
a first cyclone that is disposed in the dust-collecting housing, the first cyclone for centrifugally separating out the dirt particles from the drawn-in air;
a plurality of secondary cyclones that are arranged to enclose the first cyclone in a radial direction and centrifugally separate out fine dirt particles from the air discharged from the first cyclone; and
a suction pipe that upwardly protrudes from a lower portion of the dust-collecting housing to allow ambient air to flow from the lower portion of the dust-collecting housing toward the first cyclone. - View Dependent Claims (18, 19)
