Abstract:

A filter assembly for a vacuum cleaner that includes a main housing having an inlet and an outlet. A motor moves air from the inlet to the outlet, and a first filter is arranged between the inlet and the outlet for filtering the air. An inner wall and an outer wall that is spaced apart from the inner wall form a cavity between the walls. The cavity is located between the first filter and the outlet. The inner wall has an inner opening that permits air to flow from the first filter into the cavity, and the outer wall has an outer opening. A back cover is removably secured to the outer wall over the outer opening to seal the cavity and guide the air from the cavity to the outlet. The back cover includes an access opening that is removably secured to the back cover over the access opening to seal the access opening. A filter cartridge is removably disposed within the cavity. The filter cartridge has a first side with a first opening and a second side opposite the first side and adjacent to the access cover with a second opening. The filter cartridge has a second filter, such as a HEPA filter, disposed therein between the first and the second openings for further filtering the air. A portion of the first side is in sealing engagement with a portion of the inner wall such that the first opening is aligned with the inner opening wherein the motor moves the air from the inner opening to the second opening.

International Classification:

A47L 536

US Classification:

15377

Abstract:

For a vacuum cleaning unit, a cleaning tool employing a rotatably driven brush and having a split manifold therein which allows a vacuum airflow to be directed to the outermost longitudinal ends of the brush without interference with a drive belt rotatably driving the brush at its approximate longitudinal midpoint. The cleaning tool includes an upper housing having a centrally disposed cut-out portion and a semi-circular portion for partially housing the brush therein. A cut-out is formed in a base portion of the upper housing. A lower housing also has a cut-out shaped identically to that of the cut-out portion of the upper housing. A front sole plate is included which is secured to the lower housing and which includes a pair of openings separated by a central portion, where the openings allow portions of the brush to protrude. Each of the upper and lower housings further have runner portions which form airflow channels through which a vacuum airflow may be generated. When the upper and lower housings are secured together, a drive belt is able to extend through the centrally disposed cut-out portion, the cut-out portion in the base of the upper housing and the cut-out portion in the lower housing to engage at its approximate longitudinal mid-point.
