Abstract
A vacuum cleaner, centrifugally separates contaminates from air and collects them in a filter assembly that includes a rotary filter connected to an exhaust port. The filter is provided with a suction grill portion at the outer circumference and a discharge port that is fluidly connected to the exhaust port of the cyclone type dust collecting apparatus. Contaminants accumulated on the outer surface of the filter are easily removed by rotating the filter in association with the dust receptacle.
Claims18
A filter assembly for a cyclone type dust collecting apparatus of a vacuum cleaner, the cyclone type dust collecting apparatus centrifugally separating contaminants from an externally-drawn air and collecting the separated contaminants therein, the filter assembly for filtering contaminants floating in an air which is discharged through an exhaust port of the cyclone the dust collecting apparatus, comprising:
- a rotary filter rotatably connected with respect to the exhaust port of the cyclone type dust collecting apparatus, the rotary filter including a suction grill portion disposed at the outer circumference and a discharge port in fluid communication with the exhaust port;
- and
- a filter rotating unit comprised of a connecting portion open in a downward direction with respect to an axis of the rotary filter:
- an operating bar extending upwardly from the bottom of the dust receptacle of the cyclone type dust collecting apparatus, for operating in association with the connecting portion of the rotary filter:
- and a rotation driving portion, disposed between the operating bar and the connecting portion, capable of rotating the rotary filter in association with the engagement and disengagement of the dust receptacle, the filter rotating unit for rotating the rotary filter within the dust collecting apparatus, thereby removing the contaminants filtered on the suction grill portion and depositing them into a removable dust receptacle engaged to the cyclone type dust collecting apparatus.
A filter assembly for use in a cyclone type dust collecting apparatus of a vacuum cleaner capable of filtering contaminants centrifugally separated from cyclonic air swirling within a dust receptacle, the cyclone type dust collecting apparatus having an exhaust port, the filter assembly comprising:
- a cylindrical rotary filter, rotatably connected with respect to the exhaust port of the cyclone type dust collecting apparatus, including a suction grill portion disposed at the outer circumference of the rotary filter and a discharge port in fluid communication with the exhaust port of the cyclone type dust collecting apparatus;
- and
- a filter rotating unit for rotating the rotary filter, whereby rotation of the rotary filter by the filter rotating unit results in removal of contaminants filtered by the suction grill portion, said filter rotating unit comprised of:
- a connecting portion opened in a downward direction with respect to an axis of the rotary filter;
- an operating bar extending upwardly from the bottom of the dust receptacle of the cyclone type dust collecting apparatus, for operating in association with the connecting portion of the rotary filter;
- and
- a rotation driving portion, disposed between the operating bar and the connecting portion, capable of rotating the rotary filter in association with the engagement and disengagement of the dust receptacle.
