Cyclone dust-collecting apparatus
First Claim
1. A cyclone dust-collecting apparatus to separate dust from air using a centrifugal force and to collect the separated dust, the cyclone dust-collecting apparatus comprising:
- a primary cyclone unit to separate dust from air;
a secondary cyclone unit disposed inside the primary cyclone unit to separate dust from air discharged from the primary cyclone unit; and
a tertiary cyclone unit disposed above the primary cyclone unit at an angle different from the primary and secondary cyclone units, wherein the primary cyclone unit comprises;
a cylindrical-shaped body having an inflow pipe formed on one side thereof at a tangent to the cylindrical-shaped body and a space formed thereinside; and
a grill pipe disposed substantially in a central portion of the cylindrical-shaped body to simultaneously function as an air outflow opening of the primary cyclone unit and as an air inflow opening of the secondary cyclone unit, wherein the grill pipe comprises a skirt to prevent dust separated from air by the primary cyclone unit from being re-scattered, and wherein the skirt has a plurality of filter pores.
