DUST-COLLECTING UNIT OF A VACUUM CLEANER FOR SMOOTHLY EXHAUSTING SUCKED AIR TO THE OUTSIDE AND IMPROVING SUCTION FORCE, BY CLEANLY REMOVING DUST FORMED IN A BENT PART

摘要

PURPOSE: A dust-collecting unit of a vacuum cleaner is provided to easily remove dust of a filter by fixing both ends of a bent part of the filter by flexible materials. CONSTITUTION: A dust-collecting unit of a vacuum cleaner comprises a cover(100) selectively closing the upper end to prevent sucked air from being exhausted to the outside in an unfiltered state; a filter assembly; and a dust-collecting casing(300) including an inlet(311) for inflow of dust and a dirt separation chamber(310) in which a cyclone air current is formed. An outlet(110) for exhaust of filtered air is formed to the middle part of the cover. The filter assembly includes a corrugated filter(230) and a filter casing(210). The corrugated filter comprises a bent part(231) bent several times to filter incoming dust and flexible fixing parts(233) for flexibly fixing both ends of the bent part. The filter casing is attached to the cover while the corrugated filter is inserted in the filter casing.
