Abstract
A vacuum cleaner has an upright support structure pivotally mounted to a cleaning head. A portable surface cleaning unit is removably mounted to the upright support structure. The portable surface cleaning unit has a cyclone chamber, a dirt collection chamber exterior to the cyclone chamber and a suction motor. When the portable surface cleaning unit is mounted to the upright support structure and the upright support structure extends upwardly from the cleaning head, the upper end wall of the dirt collection chamber and the cyclone chamber end wall are an openable upper wall of the portable surface cleaning unit.
Claims20
A vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet provided in a cleaning head to a clean air outlet, the cleaning head having a front end with the dirty air inlet and a rear end;
- (b) an upright support structure pivotally mounted to the cleaning head;
- (c) a portable surface cleaning unit that is removably mounted to the upright support structure, the portable surface cleaning unit having the clean air outlet with a cyclone and a suction motor that are positioned in the air flow path;
- (d) the cyclone comprising a cyclone chamber extending along a cyclone chamber axis, the cyclone chamber comprising a cyclone chamber first end, an opposed cyclone chamber second end spaced apart from the cyclone chamber first end and a cyclone chamber sidewall extending between the first and second cyclone chamber ends, the cyclone chamber first end comprising a cyclone chamber first end wall and a dirt outlet and the opposed cyclone chamber second end comprising a cyclone chamber second end wall, a fluid inlet and a fluid outlet, wherein the cyclone chamber first end wall is openable whereby the cyclone chamber is opened, wherein the fluid inlet and the fluid outlet are positioned below the dirt outlet when the portable surface cleaning unit is mounted to the upright support structure and the upright support structure extends upwardly from the cleaning head;
- (e) the air outlet comprises a tapered member extending axially inwardly from the cyclone chamber second end wall, the tapered member comprises a longitudinally extending porous media and has a first end located at the cyclone chamber second end wall and a narrower second end spaced axially inwardly from the cyclone chamber second end wall;
- and,
- (f) a dirt collection chamber exterior to the cyclone chamber and in communication with the dirt outlet to receive dirt therefrom, the dirt collection chamber extending along a dirt collection chamber axis, the dirt collection chamber comprising a dirt collection chamber first end wall, an opposed dirt collection chamber second end wall spaced apart from the first collection chamber first end wall, and a dirt collection chamber sidewall extending therebetween, the dirt collection chamber first end wall being openable whereby the dirt collection chamber is opened,
- wherein when the portable surface cleaning unit is mounted to the upright support structure and the upright support structure extends upwardly from the cleaning head, the dirt collection chamber first end wall and the cyclone chamber first end wall are an openable upper wall of the portable surface cleaning unit.
