Abstract
A surface cleaning apparatus uses an inverted cyclone. An air flow path extends from a dirty air inlet to a clean air outlet. A suction motor is positioned in the air flow path. The inverted cyclone is downstream from the dirty air inlet in a first cyclonic cleaning stage. The cyclone defines a cyclone chamber having a lower air inlet, a lower air outlet and an upper dirt outlet. An openable dirt collection chamber is in communication with the upper dirt outlet.
Claims15
A hand held carriable surface cleaning apparatus having an upper end, a lower end, a rear end and a front end, the hand held surface cleaning apparatus comprising:
- a) an air flow path extending from a dirty air inlet to a clean air outlet;
- b) a first cyclonic cleaning stage comprising a cyclone downstream from the dirty air inlet, the cyclone defining a cyclone chamber having a lower air inlet, a lower air outlet and an upper dirt outlet and an openable dirt collection chamber, the dirt collection chamber in communication with the upper dirt outlet;
- c) a suction motor positioned in the air flow path;
- d) a handle provided on the upper end of the hand carriable surface cleaning apparatus, the handle extending forwardly from the rear end of the hand carriable surface cleaning apparatus whereby the handle overlies at least a portion of the first cyclonic cleaning stage and the suction motor, the handle having an actuator provided thereon;
- and,
- e) a filter positioned directly below the cyclone air outlet
- wherein the handle has outer perimeter extending between a front end of the handle and a rear end of the handle, a front section having a front section outer perimeter, a central section having a central section outer perimeter and a rear section having a rear section outer perimeter, and each of the front section outer perimeter, the central section outer perimeter and the rear section outer perimeter has an equal length in a forward rearward direction, and
- wherein, the suction motor has a center provided between a front end and a rear end of the suction motor, the rear end of the handle is at the rear end of the suction motor and the central section of the handle overlies the center of the suction motor.
A surface cleaning apparatus having an upper end, a lower end, a rear end and a front end, the surface cleaning apparatus comprising:
- a) an air flow path extending from a dirty air inlet to a clean air outlet;
- b) a first cyclonic cleaning stage comprising an cyclone downstream from the dirty air inlet, the cyclone defining a cyclone chamber having a longitudinally extending axis, a lower cyclone air inlet, a lower cyclone air outlet, an upper dirt outlet;
- c) an openable dirt collection chamber in communication with the dirt outlet, the dirt collection chamber having a lower openable end portion that comprises a dirt collection surface;
- d) a suction motor positioned in the air flow path;
- e) a handle provided on the upper end of the first cyclonic cleaning stage, the handle extending from the rear end of the surface cleaning apparatus forwardly to overlie at least a portion of the first cyclonic cleaning stage;
- and,
- f) a filter positioned directly below the cyclone air outlet
- wherein the handle has outer perimeter extending between a front end of the handle and a rear end of the handle, a front section having a front section outer perimeter, a central section having a central section outer perimeter and a rear section having a rear section outer perimeter, and each of the front section outer perimeter, the central section outer perimeter and the rear section outer perimeter has an equal length in a forward rearward direction, and
- wherein, the suction motor has a center provided between a front end and a rear end of the suction motor, the rear end of the handle is at the rear end of the suction motor and the central section of the handle overlies the center of the suction motor.
