Abstract

An indoor vacuum cleaner comprises a dirty air inlet, a handle, a cyclone separator having an outer wall, a fluid inlet downstream from the dirty air inlet and a fluid outlet, a plate having a cyclone chamber surface and positioned to substantially divide the cyclone separator into a cyclone chamber and a dirt collection chamber, each of the cyclone chamber and the dirt collection chamber having an outer wall, the outer wall of each of the cyclone chamber and the dirt collection chamber having an outer perimeter, the dirt collection chamber having a cyclone chamber end spaced from a dirt collection floor, a passage extending between the cyclone chamber and the dirt collection chamber, the passage configured such that separated dirt travels at least outwardly as the dirt travels through the passage and, an air flow motor.

Claims

1. A surface cleaning apparatus cleaner comprising:

(a) a dirty air inlet;

(b) a handle;

(c) a cyclone chamber having a longitudinal axis, a fluid inlet downstream from the dirty air inlet, a dirt outlet comprising an opening at a first end of the cyclone chamber and a fluid outlet spaced from the first end, the opening having an area;

(d) a plate having a cyclone chamber surface and the cyclone chamber surface of the plate having an area that is larger than the area of the opening;

(e) a passage extending between the cyclone chamber and a dirt collection chamber, the passage defined at least in part by first and second opposed walls extending at an angle to the longitudinal axis such that separated dirt travels at least outwardly as the dirt travels through the passage; and

,

(f) an air flow motor.

2. The surface cleaning apparatus of claim 1 wherein the passage is formed between the cyclone chamber surface of the plate and an end surface of the first end of the cyclone chamber.

3. The surface cleaning apparatus of claim 2 wherein the cyclone chamber has an inner surface adjacent the first end and the dirt collection chamber has an inner surface adjacent the dirt outlet, the plate is positioned spaced from the end surface and the inner surface of the dirt collection chamber has a perimeter that is larger then a perimeter of the inner surface of the cyclone chamber adjacent the first end.

4. The surface cleaning apparatus of claim 1 wherein the plate comprises a disc positioned adjacent a cyclone chamber end of the dirt collection chamber and the dirt collection chamber extends under at least a portion of the disc.

5. The surface cleaning apparatus of claim 1 further comprising a flow director having a flow directing surface that extends inwardly and downwardly into the cyclone chamber from an outer wall of the cyclone chamber to a position spaced from the plate and the passage is formed between the flow director and the cyclone chamber surface of the plate.

6. The surface cleaning apparatus of claim 1 wherein the passage extends generally transverse to a longitudinal axis of the cyclone chamber.

7. The surface cleaning apparatus of claim 1 wherein the opening is in a plane transverse to the longitudinal axis of the cyclone chamber.

8. The surface cleaning apparatus of claim 1 wherein the first and second opposed walls extend transversely.

9. The surface cleaning apparatus of claim 1 wherein the passage is L shaped in vertical section taken along the longitudinal axis.

10. A surface cleaning apparatus comprising:

(a) a dirty air inlet;

(b) a handle;

(c) a cyclone chamber having a longitudinal axis, a fluid inlet downstream from the dirty air inlet, a fluid outlet and a dirt outlet at a dirt outlet end of the cyclone chamber;

(d) a plate having a cyclone chamber surface;

(e) a passage extending between the cyclone chamber surface and an end surface at the dirt outlet end of the cyclone chamber, wherein the dirt outlet comprises an opening in the end surface, the opening is in a plane transverse to the longitudinal axis of the cyclone chamber, the cyclone chamber surface having an area that is larger then the area of the opening and,

(f) an air flow motor.

11. The surface cleaning apparatus of claim 10 wherein the cyclone chamber has an inner surface adjacent the opening and the dirt collection chamber has an inner surface adjacent the plate, the plate is positioned spaced from the opening and the inner surface of the dirt collection chamber has a perimeter that is larger then a perimeter of the inner surface of the cyclone chamber adjacent the opening.

12. The surface cleaning apparatus of claim 10 wherein the plate comprises a disc positioned adjacent a cyclone chamber end of the dirt collection chamber and the dirt collection chamber extends under at least a portion of the disc.

13. The surface cleaning apparatus of claim 10 further comprising a flow director having a flow directing surface that extends inwardly into the cyclone chamber from an outer wall of the cyclone chamber to a position spaced from the plate and the passage is formed between the flow director and the cyclone chamber surface of the plate.

14. The surface cleaning apparatus of claim 10 wherein the passage extends generally transverse to a longitudinal axis of the cyclone chamber.

15. The surface cleaning apparatus of claim 10 wherein the passage comprising a first portion that extends in a first direction and a second portion that extends in a second direction that is at an angle to the first direction.

16. The surface cleaning apparatus of claim 10 wherein the passage is L shaped in vertical section taken along the longitudinal axis.

17. A surface cleaning apparatus comprising:

(a) a dirty air inlet;

(b) a handle;

(c) a cyclone chamber having a longitudinal axis, a fluid inlet downstream from the dirty air inlet, a dirt outlet at a first end of the cyclone chamber;

(d) a plate having a cyclone chamber surface;

(e) a passage extending between the cyclone chamber and a dirt collection chamber, the passage comprising a first portion that extends in a first direction and a second portion that extends in a second direction that is at an angle to the first direction; and

,

(f) an air flow motor.

18. The surface cleaning apparatus of claim 17 wherein the first portion conveys separated dirt outwardly.

19. The surface cleaning apparatus of claim 18 wherein the second portion conveys separated dirt away from the cyclone chamber.

20. The surface cleaning apparatus of claim 17 wherein the first portion extends transversely to the longitudinally extending axis.

21. The surface cleaning apparatus of claim 20 wherein the second portion extends longitudinally.

22. The surface cleaning apparatus of claim 20 wherein the fluid outlet is spaced from the first end.

23. The surface cleaning apparatus of claim 17 wherein the passage is L shaped in vertical section taken along the longitudinal axis.
