CYCLONE DUST COLLECTOR AND VACUUM CLEANER

摘要

A vacuum cleaner having a cyclone dust collecting device is provided to reduce noise generated in an upper cover by installing a noise reducing part between discharge holes of a second cyclone chamber and the upper cover. A vacuum cleaner having a cyclone dust collecting device includes a cyclone body(100), an upper cover(120), and a noise reducing part(130). The cyclone body includes a first cyclone chamber, a second cyclone chamber(142), and a discharge hole(162). The first cyclone chamber centrifuges the inhaled air primarily. The second cyclone chamber centrifuges the inhaled air secondly. The discharge hole discharges the inhaled air from the second cyclone chamber. The upper cover covers an upper side of the cyclone body, and has an inner wall facing with a plurality of discharge holes. The noise reducing part is installed between the inner wall of the upper cover and a plurality of discharge holes, and reduces the noise generated in the upper cover.
