Abstract
A surface cleaning apparatus comprises an air flow passage extending from a dirty air inlet to a clean air outlet and a suction motor. The surface cleaning apparatus may also comprise a cyclone chamber provided in the air flow passage. The cyclone chamber may comprise a cyclone air inlet, a cyclone air outlet and a dirt outlet. The surface cleaning apparatus may comprise a dirt collection chamber having a dirt inlet, a dirt collection chamber first end, an opposed dirt collection chamber second end and a longitudinally extending sidewall. Various design improvements are provided.
Claims27
A surface cleaning apparatus comprising:
- (a) an air flow passage extending from a dirty air inlet to a clean air outlet and including a suction motor;
- (b) a cyclone bin assembly positioned in the air flow passage and comprising a cyclone chamber comprising a cyclone air inlet, a cyclone air outlet and a dirt outlet, and a dirt collection chamber having a radial outer wall, the cyclone bin assembly having a bin first end, an opposed bin second end axially spaced apart from the bin first end in an axial direction, the radial outer wall comprising a first sidewall portion extending at least nearly parallel to the axial direction, a second sidewall portion extending at least nearly parallel to the axial direction, the first sidewall portion having a first width in a lateral direction generally orthogonal to the axial direction, the second sidewall portion having a second width in the lateral direction that is different to the first width and a first inclined transition portion connecting the first sidewall portion and the second sidewall portion and widening from the first width to the second width, wherein the first inclined transition portion is located at the cyclone air inlet.
A surface cleaning apparatus comprising:
- a) an air flow passage extending from a dirty air inlet to a clean air outlet and including a suction motor;
- b) a cyclone chamber disposed within the air flow path and comprising a cyclone air inlet, a cyclone air outlet and a dirt outlet;
- c) a dirt collection chamber external the cyclone chamber and in communication with the cyclone chamber dirt outlet, a dirt collection chamber first end, an opposed dirt collection chamber second end spaced apart from the dirt collection chamber first end along a chamber axis and a sidewall extending between the dirt collection chamber first and second ends, the sidewall comprising a first sidewall portion extending at least nearly parallel to the chamber axis toward the dirt collection chamber first end and having a first width in a lateral direction that is generally orthogonal to the chamber axis, a second sidewall portion extending at least nearly parallel to the chamber axis and disposed between the first sidewall portion and the dirt collection chamber second end and having a second width in the lateral direction that is different than the first width, and an inclined transition sidewall portion extending from the first sidewall portion to the second sidewall portion and connecting the first sidewall portion and the second sidewall portion wherein the cyclone air outlet is positioned adjacent the inclined transition sidewall portion in an outer wall of the cyclone chamber.
A surface cleaning apparatus comprising:
- a) an air flow passage extending from a dirty air inlet to a clean air outlet and including a suction motor;
- b) a cyclone chamber disposed within the air flow path and comprising a cyclone air inlet, a cyclone air outlet, a dirt outlet, a cyclone chamber first end, an opposed cyclone chamber second end axially spaced apart from the cyclone chamber first end in an axial direction and a cyclone chamber sidewall extending therebetween;
- c) a dirt collection chamber external to the cyclone chamber and in communication with the cyclone chamber dirt outlet, a dirt collection chamber first end, an opposed dirt collection chamber second end spaced apart from the dirt collection first end along a chamber axis and a dirt collection chamber sidewall extending between the dirt collection chamber first and second ends, the cyclone chamber second end being positioned between the cyclone chamber first end and the second end of the dirt collection chamber, the dirt collection chamber sidewall comprising a first sidewall portion extending at least nearly parallel to the chamber axis toward the dirt collection chamber first end and having a first width in a lateral direction that is generally orthogonal to the chamber axis, a second sidewall portion extending at least nearly parallel to the chamber axis and disposed between the first sidewall portion and the dirt collection chamber second end and having a second width in the lateral direction that is different than the first width, and an inclined transition sidewall portion extending from the first sidewall portion to the second sidewall portion and connecting the first sidewall portion and the second sidewall portion wherein the first width and the second width are wider than a maximum width of the cyclone chamber sidewall.
