Multi-cyclone apparatus and vacuum cleaner having the same

摘要

A multi-cyclone apparatus is capable of separating and collecting contaminants by three stages. The multi-cyclone apparatus has a first collecting unit (10) which separates large-sized contaminants from an air which is drawn through an air suction port (11), a cyclone body (20) comprising a second cyclone (30) which is communicated with the first collecting unit (10) and separates middle-sized contaminants from the drawn air, and a plurality of third cyclones (40) arranged around the second cyclone (30) and separate small-sized contaminants from the drawn air, an air discharge port (61) communicated with the cyclone body (20), through which the air is discharged after passing through the third cyclones (40), and a contaminant receptacle (70) provided to a lower end of the cyclone body (20), and collects contaminants separated from the second (30) and the third cyclones (40).
