Abstract

A surface cleaning apparatus includes a cyclone bin assembly that includes a cyclone chamber and a dirt collection chamber. A first end of the cyclone bin assembly includes at least a portion of the cyclone chamber and at least a portion of the dirt collection chamber and at least a portion of a sidewall separating the dirt collection chamber and the cyclone chamber. The first end of the cyclone bin assembly is rotationally mounted between a closed position and an open position in which an end of the cyclone chamber and an end of the dirt collection chamber are opened.

First claim

The invention claimed is:

1. A hand vacuum cleaner comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet with a suction motor positioned in the air flow path;
(b) a main body comprising a handle and the suction motor; and,
(c) a cyclone bin assembly comprising a cyclone chamber positioned in the air flow path and a dirt collection chamber, the cyclone chamber has a cyclone air inlet, a cyclone air outlet, a dirt outlet, a cyclone chamber front end having a cyclone chamber front end wall, a cyclone chamber rear end having a cyclone chamber rear end wall and cyclone axis of rotation that extends between the cyclone chamber front end wall and the cyclone chamber rear end wall, the dirt collection chamber having a dirt collection chamber front end having a dirt collection chamber front end wall and an axially spaced apart dirt collection chamber rear end having dirt collection chamber rear end wall, a portion of the dirt collection chamber is spaced from the cyclone chamber in a direction transverse to the cyclone axis of rotation whereby the portion faces towards the cyclone chamber and is separated from the cyclone chamber by a sidewall,
wherein a front end of the cyclone bin assembly comprises at least a portion of the cyclone chamber, at least a portion of the dirt collection chamber and at least a portion of the sidewall, the front end of the cyclone bin assembly is rotationally mounted between a closed position and an open position in which the rear end of the cyclone chamber and the rear end of the dirt collection chamber are opened.

2. The hand vacuum cleaner of claim 1 wherein the dirt outlet is provided in the sidewall.

3. The hand vacuum cleaner of claim 1 wherein the cyclone air inlet is provided at the cyclone chamber front end and the cyclone air outlet is provided at the cyclone chamber rear end.

4. The hand vacuum cleaner of claim 3 wherein the dirt outlet is provided in the sidewall.

5. The hand vacuum cleaner of claim 1 wherein the dirt outlet comprises an opening in the sidewall that extends axially inwardly into the cyclone chamber from the cyclone chamber rear end wall.

6. The hand vacuum cleaner of claim 1 further comprising an inlet conduit, the dirty air inlet is located at an inlet end of the inlet conduit and the inlet conduit is part of the front end of the cyclone bin assembly.

7. The hand vacuum cleaner of claim 1 wherein the dirt collection chamber front end is positioned axially forwardly from the cyclone chamber front end whereby the cyclone axis of rotation extends through a portion of the dirt collection chamber that is located axially outwardly from the cyclone chamber front end.

8. The hand vacuum cleaner of claim 1 wherein the front end of the cyclone bin assembly is rotationally mounted to a rear end of the cyclone bin assembly.

9. The hand vacuum cleaner of claim 1 wherein the front end of the cyclone bin assembly is rotationally mounted at a location of the rear end wall of the cyclone chamber.

10. The hand vacuum cleaner of claim 1 wherein the front end of the cyclone bin assembly is rotationally mounted to a rear end of the cyclone bin assembly at a location midway along an axial length of the cyclone bin assembly.

11. A surface cleaning apparatus comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet with a suction motor positioned in the air flow path; and,
(b) a cyclone bin assembly comprising a cyclone chamber positioned in the air flow path and a dirt collection chamber, the cyclone chamber has a cyclone air inlet, a cyclone air outlet, a dirt outlet, a cyclone chamber first end having a cyclone chamber first end wall, a cyclone chamber second end having a cyclone chamber second end wall and cyclone axis of rotation that extends between the cyclone chamber first end wall and the cyclone chamber second end wall, the dirt collection chamber having a dirt collection chamber first end having a dirt collection chamber first end wall and an axially spaced apart dirt collection chamber second end having dirt collection chamber second end wall, a portion of the dirt collection chamber is spaced from the cyclone chamber in a direction transverse to the cyclone axis of rotation whereby the portion faces towards the cyclone chamber and is separated from the cyclone chamber by a sidewall,
wherein a first end of the cyclone bin assembly comprises at least a portion of the cyclone chamber, at least a portion of the dirt collection chamber and at least a portion of the sidewall, the first end of the cyclone bin assembly is rotationally mounted between a closed position and an open position in which the second end of the cyclone chamber and the second end of the dirt collection chamber are opened.

12. The surface cleaning apparatus of claim 11 wherein the dirt outlet is provided in the sidewall.

13. The surface cleaning apparatus of claim 11 wherein the cyclone air inlet is provided at the cyclone chamber first end and the cyclone air outlet is provided at the cyclone chamber second end.

14. The surface cleaning apparatus of claim 13 wherein the dirt outlet is provided in the sidewall.

15. The surface cleaning apparatus of claim 11 wherein the dirt outlet comprises an opening in the sidewall that extends axially inwardly into the cyclone chamber from the cyclone chamber second end wall.

16. The surface cleaning apparatus of claim 11 further comprising an inlet conduit, the dirty air inlet is located at an inlet end of the inlet conduit and the inlet conduit is part of the first end of the cyclone bin assembly.

17. The surface cleaning apparatus of claim 11 wherein the dirt collection chamber first end is positioned axially outwardly from the cyclone chamber first end whereby the cyclone axis of rotation extends through a portion of the dirt collection chamber that is located axially outwardly from the cyclone chamber first end.

18. The surface cleaning apparatus of claim 11 wherein the front end of the cyclone bin assembly is rotationally mounted to a rear end of the cyclone bin assembly.

19. The surface cleaning apparatus of claim 11 wherein the front end of the cyclone bin assembly is rotationally mounted at a location of the second end wall of the cyclone chamber.

20. The surface cleaning apparatus of claim 11 wherein the front end of the cyclone bin assembly is rotationally mounted to a rear end of the cyclone bin assembly at a location midway along an axial length of the cyclone bin assembly.
