Abstract:
1. An upright suction cleaner comprising: a floor engaging base unit; a body unit pivotally mounted on the base unit; a suction generating device disposed on one of said base unit and body unit; a dirt collecting enclosure disposed on said body unit, said dirt collecting enclosure having a first and a second chamber formed therein; an inlet port cooperatively engaging a portion of said first chamber, said inlet port allowing communication of airflow into said first chamber; a first filter member disposed in said first chamber and operating in conjunction with said inlet port for imparting to such airflow communicated thereto, a vortex action; wherein said first filter member is effective so as to remove from such airflow, particles of debris of a larger size and deposit such larger sized debris into said first chamber, said first filter member is further effective for communicating therethrough into said second chamber, the remaining airflow from said first chamber; wherein such remaining airflow from said first chamber, while still having associated therewith, a cyclonic action, deposits into said second chamber, debris of a size smaller than that which was deposited in said first chamber; a cyclone chamber disposed above said dirt collecting enclosure, said cyclone chamber effective for communicating airflow remaining from said second chamber, into a third chamber, said cyclone chamber further effective for imparting additional cyclonic action to said remaining airflow; and, a second filter member disposed in said third chamber, said second filter member being effective for removing from said remaining airflow, debris of a size smaller than that removed by said second chamber; wherein said second chamber is a tube disposed at one side of said first chamber and further wherein said second chamber is of a diameter substantially smaller than the diameter of said first chamber so that, when gripped, said second chamber acts as a handle for transport of said dirt collecting enclosure.
