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.

7. The vacuum cleaner of claim 1 wherein the dirt collection chamber has a bottom that is openable.

8. The surface cleaning apparatus of claim 1 wherein the portion of the cyclone chamber surface that faces the outwardly extending portion of the outer wall of the cyclone chamber extends generally parallel to the outwardly extending portion.

9. The vacuum cleaner of claim 1 wherein fluid outlet comprises a tube having an inlet and the tube extends along the axis of the cyclone chamber to a position below the fluid inlet and has an end that is spaced from the plate.

10. The vacuum cleaner of claim 9 further comprising a screen in covering relation to the inlet of the air flow tube and the screen is spaced from the plate.

11. An indoor vacuum cleaner comprising:

(a) a dirty air inlet;

(b) a handle;

(c) a cyclone chamber having an outer wall, an associated dirt collection chamber, a fluid inlet downstream from the dirty air inlet and a fluid outlet, 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 surface;

(d) a plate having a cyclone chamber surface and defining at least in part 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;

(e) a flow director having a flow directing surface that extends inwardly and downwardly into the cyclone chamber from the outer wall of the cyclone chamber to a position longitudinally spaced from and above the plate, whereby the flow director overlies a portion of the plate, and the passage is formed between the flow director and the cyclone chamber surface of the plate; and

,

(f) an air flow motor.

12. The vacuum cleaner of claim 11 further comprising an annular dirt collection region collinear with the cyclone chamber and separated therefrom by an inner annular wall that has a terminal end spaced from the plate and the passage is formed between the terminal end and the cyclone chamber surface of the plate.

13. The vacuum cleaner of claim 11 wherein the passage has a height that is less than ⅙

the diameter.

14. The vacuum cleaner of claim 11 wherein the passage has a height that is less than 1/10 the diameter.

15. The vacuum cleaner of claim 11 wherein the passage has a height that is less than 1/20 the diameter.

16. An indoor vacuum cleaner comprising:

(a) a dirty air inlet;

(b) a handle;

(c) a cyclone chamber having an outer wall, a fluid inlet downstream from the dirty air inlet, a dirt outlet and a fluid outlet;

(d) a plate having a cyclone chamber surface that extends under the fluid outlet and is longitudinally spaced from and is positioned facing the fluid outlet, each of the cyclone chamber and the dirt collection chamber having an outer wall, the cyclone chamber surface is unobstructed;

(e) 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

,

(f) an air flow motor.

17. The surface cleaning apparatus of claim 16 wherein the cyclone chamber surface of the plate and an end surface of the outer wall of the cyclone chamber are longitudinally spaced apart and face each other and a gap therebetween comprises the passage.
