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.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS [0001] This application claims the benefit of Korean Application No. P2005-0049801, filed on Jun. 10, 2005, which is hereby incorporated by reference as if fully set forth herein.

AI Technical Summary

Benefits of technology

[0016] An object of the present invention is to provide a vacuum cleaner which enables easy separation of a dust collecting filter from the vacuum cleaner, for convenient washing or replacement of the dust collecting filter.

[0017] Another object of the present invention is to provide a vacuum cleaner which enables a user to dismount the dust collecting filter easily, so that the user can determine an extent of accumulation of dust in the dust collecting filter.

[0019] To achieve these objects and other advantages and in accordance with the purpose of the invention, as embodied and broadly described herein, a vacuum cleaner includes 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 or the cleaner body for housing the dust collecting filter therein and drawing out of the dust collecting device or the cleaner body 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.

[0020] Preferably, the vacuum cleaner further includes a filter mounting portion at a portion the filter housing is to be mounted thereto, having an opening for mounting the filter housing. More preferably, the filter assembly further includes a sealing member at a portion the filter housing is secured to the filter mounting portion for preventing the air from leaking to an outside of the filter assembly.

[0021] In the meantime, preferably, the filter housing includes a mesh at at least one of an upper and a lower portion of the filter housing for easy reception of the filter. More preferably, the filter housing includes a holding member for holding the dust collecting filter. Moreover, more preferably, the filter assembly further includes a handle on a front of the filter housing.

Problems solved by technology

However, the related art dust collecting device has a problem in that the separation of the dust collecting filter from the cleaner body for periodic washing or replacement is cumbersome.

Moreover, much effort is required for the user even in determining an extent of accumulation of dust in the dust collecting filter for determining a time for washing or replacing the dust collecting filter.
