CYCLONIC SURFACE CLEANING APPARATUS WITH EXTERNALLY POSITIONED DIRT CHAMBER
A surface cleaning apparatus comprises a floor cleaning unit and an upright section comprising a handle drivingly connected to the surface cleaning head. The surface cleaning apparatus also comprises a cyclone mounted on the upright section and positioned in the air flow passage. The cyclone is inverted and/or has an external dirt collection chamber.
1 . An upright surface cleaning apparatus comprising:
(a) a floor cleaning unit comprising a surface cleaning head having a dirty air inlet, a cleaning head air outlet and an upright section comprising a handle drivingly connected to the surface cleaning head;
(b) a cyclone unit positioned in the air flow passage, the cyclone unit comprising a cyclone having an air inlet located at a lower end of the cyclone and an air outlet and a dirt outlet provided at an upper end of the cyclone, and a dirt collection chamber exterior to the cyclone and surrounding at least a portion of the cyclone;
(c) a suction motor positioned in the air flow path; and,
(d) a surface cleaning unit removably mounted to the handle wherein the surface cleaning unit comprises the cyclone unit and the suction motor.
2 . The surface cleaning apparatus of claim 1 wherein the cyclone and the dirt collection chamber are concurrently openable.
3 . The surface cleaning apparatus of claim 1 wherein the cyclone is positioned interior of the dirt collection chamber.
4 . The surface cleaning apparatus of claim 1 further comprising a plate facing the dirt outlet.
5 . The surface cleaning apparatus of claim 4 wherein the plate is mounted to an upper end of the cyclone unit.
6 . The surface cleaning apparatus of claim 5 wherein the cyclone is an inverted cyclone having an air inlet and an air outlet at a lower end of the cyclone.
7 . The surface cleaning apparatus of claim 1 further comprising a vortex finder that is provided on an openable door of the cyclone.
8 . The surface cleaning apparatus of claim 1 wherein the handle comprises a portion of the air flow path.
9 . An upright surface cleaning apparatus comprising:
(a) a floor cleaning unit comprising a surface cleaning head having a dirty air inlet, a cleaning head air outlet and an upright section comprising a handle drivingly connected to the surface cleaning head;
(b) a cyclone unit mounted on the upright section and positioned in the air flow passage, the cyclone unit comprising a cyclone having an air inlet located at a lower end of the cyclone and an air outlet and a dirt outlet provided at an upper end of the cyclone, and a dirt collection chamber exterior to the cyclone and surrounding at least a portion of the cyclone wherein the cyclone unit is removable in a closed configuration; and,
(c) a suction motor positioned in the air flow path.
10 . The surface cleaning apparatus of claim 9 further comprising a surface cleaning unit removably mounted to the handle wherein the surface cleaning unit comprises the cyclone unit and the suction motor.
11 . The surface cleaning apparatus of claim 9 wherein the cyclone and the dirt collection chamber are concurrently openable.
12 . The surface cleaning apparatus of claim 9 wherein the cyclone is positioned interior of the dirt collection chamber.
13 . The surface cleaning apparatus of claim 9 further comprising a plate facing the dirt outlet.
14 . The surface cleaning apparatus of claim 13 wherein the plate is mounted to an upper end of the cyclone unit.
15 . The surface cleaning apparatus of claim 14 wherein the cyclone is an inverted cyclone having an air inlet and an air outlet at a lower end of the cyclone.
16 . The surface cleaning apparatus of claim 9 further comprising a vortex finder that is provided on an openable door of the cyclone.
