Abstract:
1. A multi cyclone collector, comprising: a first cyclone collector that draws in external air and separates and collects a plurality of first particles from the external air; a plurality of second cyclone collectors arranged in fluid communication with the first cyclone collector so as to receive air from which the plurality of first particles has been separated by the first cyclone collector, and to separate and collect a plurality of second particles from the received air; a collecting container that collects the plurality of second particles separated by the plurality of second cyclone collectors; and a case in which the first and plurality of second cyclone collectors are received, wherein the case is formed in a polygonal shape having at least one interior corner formed by two adjacent vertical walls, wherein some of the plurality of second cyclone collectors are positioned in a circular arrangement along an outer circumferential portion of the first cyclone collector, and a remainder of the plurality of second cyclone collectors are positioned in a non-circular arrangement at the at least one interior corner and along one of the two adjacent vertical walls of the case such that a distance between the first cyclone collector and a second cyclone collector positioned at the at least one interior corner is greater than a distance between the first cyclone collector and a second cyclone collector arranged along the outer circumferential portion of the first cyclone collector.
