Abstract
A surface cleaning apparatus has a cyclone chamber having a longitudinal cyclone axis of rotation wherein the dirt outlet is defined by a gap between the sidewall of the cyclone and a plate positioned at the dirt outlet end of the cyclone.
Claims20
A vacuum cleaner comprising:
- (a) an air flow path extending from a dirty air inlet to a clean air outlet;
- (b) a cyclone and a suction motor provided in the air flow path;
- (c) the cyclone comprising a cyclone chamber having a central longitudinal axis, the cyclone having a first end having a first end wall, an axially spaced apart second end, a cyclone chamber sidewall located between the first and second ends, a cyclone air inlet provided at the first end, a cyclone air outlet provided at the first end and a dirt outlet provided at the second end, wherein the first end of the cyclone chamber sidewall is located at the first end of the cyclone and the second end of the sidewall is spaced from the first end;
- (d) a plate located at the second end, the plate having a plate perimeter, a cyclone chamber face that faces towards the first end;
- and,
- (e) a dirt collection region in communication with the cyclone chamber via the dirt outlet,
- wherein the dirt outlet comprises an axial spacing between at least a portion of the cyclone chamber sidewall and the plate, and the plate has a non-circular shape in a plate plane that is transverse to the central longitudinal axis and that is located at the plate, and
- wherein the plate is moveably mounted between a closed position, in which the plate is positioned for operation of the cyclone and an open position wherein the plate is moved to provide access to the cyclone chamber.
