25. A method for separating a mixture of dirt and air inducted into a vacuum cleaner apparatus by a suction motor, said method comprising the steps of:
- directing said mixture of dirt and air to a bagless dustcup assembly comprising a handle assembly secured to an upstanding handle of said vacuum cleaner apparatus, a dustcup connected to said handle assembly and to a body portion of said vacuum cleaner apparatus, and a motor intake adaptor connected to said dustcup and to said suction motor;
drawing said mixture of dirt and air through a chimney extension included in a top-hinged support included in said handle assembly;
further drawing said mixture of dirt and air from said chimney extension through an inlet passageway provided in a plenum chamber member of a filter/cyclone assembly included in said dustcup;
drawing said mixture of dirt and air from said inlet passageway of said plenum chamber through a volute passageway defined by a volute structure having a first opening provided in a cyclone module included in said filter/cyclone assembly and a second opening included in said volute passageway, said second opening being in fluid communication with a dustcup chamber;
directing said mixture of dirt and air from said second opening of said volute passageway tangentially against an inner wall of a circular upper region of said dustcup chamber;
allowing said mixture of dirt and air to flow around inner wall of said circular upper region to a downward-ramped, spiral portion of said volute structure;
allowing said mixture of dirt and air to contact and flow along said downward-ramped, spiral portion of said volute structure and to thereby be caused to spirally flow downward to a closed bottom portion of said dustcup chamber;
allowing said mixture of dirt and air to contact said closed bottom portion of said dust cup chamber and thereby cause a portion of the dirt contained said mixture of dirt and air to become separated from said mixture by contact with said closed bottom portion;
inducing an upward flow of said mixture of dirt and air in a central region of said dustcup chamber toward a filter assembly connected to said cyclone module;
passing said mixture of dirt and air through said filter assembly and thereby producing a stream of substantially clean air;
passing said stream of substantially clean air through a plenum chamber defined by said cyclone module and by said plenum chamber member included in said filter/cyclone assembly;
directing said stream of substantially clean air from said plenum chamber to a dustcup passageway provided in said dustcup;
passing said stream of substantially clean air through said dustcup passageway and to a walled structure included in said motor intake adaptor; and
passing said stream of substantially clean air through a passageway defined by said walled structure and into an intake of said suction motor. - View Dependent Claims (26, 27, 28)
