Multi-cyclone apparatus and vacuum cleaner having the same
First Claim
1. A multi-cyclone apparatus, comprising:
- a first collecting unit having an air suction port, the first collecting unit separating large-sized contaminants from an air that is drawn through the air suction port;
a cyclone body comprising a second cyclone in fluid communication with the first collecting unit and a plurality of third cyclones arranged around and in fluid communication with the second cyclone, the second cyclone separating middle-sized contaminants from the drawn air and the plurality of third cyclones separating small-sized contaminants from the drawn air;
an air discharge port in fluid communication with the cyclone body, through which the air is discharged after passing through the plurality of third cyclones; and
a contaminant receptacle provided at a lower end of the cyclone body, the contaminant receptacle collecting the middle-sized and small-sized contaminants.

Abstract
A multi-cyclone apparatus is capable of separating and collecting contaminants by three stages. The multi-cyclone apparatus has a first collecting unit which separates large-sized contaminants from an air which is drawn through an air suction port, a cyclone body comprising a second cyclone which is communicated with the first collecting unit and separates middle-sized contaminants from the drawn air, and a plurality of third cyclones arranged around the second cyclone and separate small-sized contaminants from the drawn air, an air discharge port communicated with the cyclone body, through which the air is discharged after passing through the third cyclones, and a contaminant receptacle provided to a lower end of the cyclone body, and collects contaminants separated from the second and the third cyclones.
