Abstract

A dust collector includes a cylindrical housing forming an outer appearance of the dust collector; a cyclone inside the housing to cause a swirling flow to separate dust from air introduced into the housing; axial inlet type swirl tubes receiving air and fine dust that have passed through the cyclone, and causing a swirling flow to separate the fine dust from the air; and a mesh surrounding an outside of the axial inlet type swirl tubes to form a boundary between the cyclone and the axial inlet type swirl tubes, wherein the axial inlet type swirl tubes are stacked in stages and the axial inlet type swirl tubes in each stage are arranged in first and second columns that are provided in opposite directions to each other, and axial lengths of the axial inlet type swirl tubes gradually increase toward the center of each stage.
