Abstract

A cyclone separator useable in a surface cleaning apparatus comprises a cyclone casing defining a cyclone chamber and having first and second opposed ends and a sidewall extending between the first and second ends. The first end is provided with a fluid inlet and the second end is provided with a dirt outlet. The dirt outlet provides a lateral outlet to a dirt collection chamber in communication with the cyclone chamber via the dirt outlet. The dirt outlet is positioned from about 90 to about 330° around the cyclone casing in a flow direction from the fluid inlet.

Claims (28)

1. A cyclone separator comprising:

(a) a cyclone casing defining a cyclone chamber having a longitudinal axis and having first and second spaced apart portions, a fluid inlet, a fluid outlet and a separated material outlet;

(b) the fluid inlet provided in the first portion;

(c) the separated material outlet provided in the second portion and providing a lateral outlet;

(d) a separated material collection chamber in communication with the separated material outlet and exterior to the cyclone chamber the separated material collection chamber is spaced axially from the cyclone chamber; and,

(e) the separated material outlet is positioned from about 90 to about 330° around the cyclone casing in a flow direction from the fluid inlet.

2. The cyclone separator of claim 1 wherein the separated material outlet is positioned from about 180 to about 300° around the cyclone casing in a flow direction from the fluid inlet.

3. The cyclone separator of claim 1 wherein the separated material outlet is positioned from about 240 to about 300° around the cyclone casing in a flow direction from the fluid inlet.

4. The cyclone separator of claim 1 wherein the separated material outlet is positioned about 270° around the cyclone casing in a flow direction from the fluid inlet.

5. The cyclone separator of claim 4 wherein the separated material collection chamber surrounds all of the cyclone chamber and the separated material collection chamber has an opposed surface facing the second end and spaced from the second end.

6. The cyclone separator of claim 1 wherein the separated material collection chamber surrounds at least a portion of the cyclone chamber.

7. The cyclone separator of claim 1 wherein the first portion includes a first end, the second portion includes an opposed second end, a sidewall extends between the first and second ends, and the separated material collection chamber has an opposed surface facing the second end and spaced from the second end.

8. A surface cleaning apparatus comprising the cyclone separator of claim 1 .

9. A cyclone separator comprising:

(a) a cyclone casing defining a cyclone chamber and having first and second spaced apart portions, a fluid inlet, a fluid outlet and a separated material outlet, wherein the first portion includes a first end, the second portion includes an opposed second end and a transition member is provided adjacent the second end, a sidewall extends between the first and second ends, the transition member having an inner surface, at least a portion of which extends in a different orientation to both the sidewall and the second end;

(b) the fluid inlet provided in the first portion;

(c) the separated material outlet provided in the second portion and providing a lateral outlet;

(d) a separated material collection chamber in communication with the separated material outlet and exterior to the cyclone chamber; and,

(e) the separated material outlet is positioned from about 90 to about 330° around the cyclone casing in a flow direction from the fluid inlet.

10. The cyclone separator of claim 9 wherein the separated material outlet is located at least partially in the transition member.

11. The cyclone separator of claim 9 wherein the separated material outlet is located in the transition member.

12. The cyclone separator of claim 11 wherein the transition member extends along an arc of a circle.

13. The cyclone separator of claim 12 wherein the circle has a radius of from 0.125 to 2 inches.

14. The cyclone separator of claim 11 wherein the sidewall and the transition member have a height and a diameter, and the height is less then the diameter.

15. The cyclone separator of claim 11 wherein the sidewall and the transition member have a height and a diameter, and the height is less then half of the diameter.

16. The cyclone separator of claim 11 wherein the fluid inlet is provided in the sidewall and the fluid inlet has an end closer to the second end then the first end.

17. The cyclone separator of claim 9 wherein the transition member is curved.

18. A surface cleaning apparatus comprising the cyclone separator of claim 9 .
