Abstract
An air cleaner adapted to filter out various types of substances through a filter assembly, as well as automatically remove the filtered substances, and a method for controlling the operation of such an air cleaner, are provided. The air cleaner may include a rotation brush unit installed on an inner wall surface of a front panel, facing a front surface of a mesh-type filter body and adapted to rotate while maintaining contact with the front surface of the filter body. When a suction operation is terminated, the rotation brush unit may to remove dust accumulated on the surface of the mesh-type filter body.
Claims15
An air cleaner, comprising:
- a case having a front opening formed therein;
- an air-drawing device and a filter assembly received in the case;
- a front panel coupled to the case to open and close the front opening of the case;
- a filter cover installed in the case, at a position corresponding to the front opening formed in the case, and at a front surface of the filter assembly;
- a mesh filter installed on a front surface of the filter cover to filter particles from air flowing into the filter assembly;
- a rotating brush assembly installed on an inner wall surface of the front panel so as to face a front surface of the mesh filter, wherein the rotating brush assembly rotates while maintaining contact with the front surface of the mesh filter when the front opening of the case is closed by the front panel, wherein the rotating brush assembly is configured to be selectively rotated and to maintain contact with the front surface of the mesh filter so as to dislodge alien substances from the front surface of the mesh filter;
- and
- a driving motor mounted at the front panel and operably coupled to the rotating brush assembly to drive the rotating brush assembly.
An air cleaner, comprising:
- a case having a receiving space formed therein configured to receive an air-drawing device and a filter assembly therein, the case having an access opening providing access to the receiving space;
- a front panel coupled to the case to open and close the access opening;
- a filter cover provided at the access opening and positioned to cover a front surface of the filter assembly, the filter cover comprising:
- a cover body having an opening formed at a central portion thereof to guide air therethrough;
- a plurality of support ribs extending radially across the opening formed in the cover body;
- and
- a drop guide formed at a lower portion of the opening in the cover body;
- a mesh filter installed on a front surface of the filter cover to filter particles from air flowing into the filter assembly;
- and
- a rotating brush assembly installed on an inner wall surface of the front panel so as to face a front surface of the mesh filter and configured to be rotated by a driving motor mounted at the front panel, wherein the rotating brush assembly rotates while maintaining contact with the front surface of the mesh filter when the access opening of the case is closed by the front panel, wherein the rotating brush assembly is configured to be selectively rotated and to maintain contact with the front surface of the mesh filter so as to dislodge alien substances from the front surface of the mesh filter,
- wherein the drop guide of the filter cover comprises:
- a plurality of stop ledges and a single-bodied stop rib respectively formed on two adjacent support ribs of the support ribs formed in the opening of the cover body;
- and
- a closing plate closing a space between the two adjacent support ribs, wherein the plurality of stop ledges protrude along a first support rib of the two adjacent support ribs and the stop rib protrudes along a second support rib of the two adjacent support ribs, with the rotating brush assembly passing through the first support rib first with reference to a rotation direction of the rotating brush assembly.
