Vacuum cleaner

Abstract

An object of the present invention is to provide a dust collecting device in a vacuum cleaner replacement of which dust collecting filter is easy. To achieve this, the present invention provides a vacuum cleaner including a cleaner body having a body suction opening, and a fan-motor assembly for forced circulation of air introduced through the body suction opening, a dust collecting device in communication with the body suction opening, the dust collecting device having a main cyclone unit for separating foreign matters from the air introduced thereto by a cyclone principle, and at least one supplementary cyclone unit around the main cyclone for separating foreign matters from the air discharged from the main cyclone unit, a suction unit having an air suction opening in communication with the body suction opening, for drawing external air through the air suction opening, and a filter assembly having a dust collecting filter in a flow passage through which the air from the supplementary cyclone unit flows for separating the foreign matters from the air, and a filter housing in the dust collecting device for housing the dust collecting filter therein and drawing out of the dust collecting device assembly in a sliding fashion, thereby permitting easy mounting/dismounting of the dust collecting filter on/off the dust collecting device, enabling convenient washing or replacement of the dust collecting filter.
