Abstract

A cyclonic separator for a suction cleaner comprises a cyclone body of which at least part is afforded by components which fit together at interfaces extending axially of the cyclone body. The components may also afford air inlet and dust outlet passages, and at least partially define a dust-collecting chamber

Claims

1. A cyclonic separator for a suction cleaner, comprising a first cyclone body formed from at least two components that fit together at multiple interfaces extending axially along the first cyclone body.

2. A separator according to claim 1 wherein at least part of the interfaces between the first cyclone body components lies in a plane which also contains an axis of the first cyclone body.

3. A separator according to claim 1 wherein at least one of an air inlet and a dust outlet is formed afforded by the first cyclone body components.

5. A separator according to claim 1 wherein portions of the first cyclone body components are semi-cylindrical or tapered.

6. A separator according to claim 1 wherein a dust collecting chamber is provided in association with at least one of the first cyclone body components.

7. A separator according to claim 1 wherein at least one of the first cyclone body components includes at least one passage extending transversely through the cyclone body.

8. A separator according to claim 7 wherein the first cyclone body components define a tangential air inlet passage and a tangential dust-outlet passage.

9. A separator according to claim 8 wherein the inlet passage is at or adjacent a first end of the first cyclone body and the dust outlet passage is at or adjacent a second end of the first cyclone body.

10. A separator according to claim 8 wherein an outlet passage for air leaving the separator is provided by an outlet member extending axially of the separator from the first end of the first cyclone body.

11. A separator according to claim 10 wherein the outlet member extends from the first end of the first cyclone body having the inlet passage.

12. A separator according to claim 11 further comprising a second cyclone body formed from at least two components that fit together at interfaces that lie in a plane which contains an axis of the second cyclone body, wherein the second cyclone body is connected to the first cyclone body.

13. A separator according to claim 12 wherein the second cyclone body includes an air inlet passage at or adjacent a first end of the second cyclone body and a dust outlet passage at or adjacent a second end of the second cyclone body, and an outlet passage for air leaving the separator is provided by an outlet member extending axially of the separator from the first end of the second cyclone body.

14. A separator according to claim 13, wherein the first and second cyclone bodies are arranged in an end-to-end relationship with one another.

15. A separator according to claim 14 wherein the axis of the first cyclone body and the axis of the second cyclone body are in alignment with one another.

16. A separator according to claim 14 wherein the first and second cyclone bodies are arranged with the air inlet of the first cyclone body and the air inlet of the second cyclone body adjacent to one another, and the dust outlet of the first cyclone body and the dust outlet of the second cyclone are located at the ends of the first and second cyclone bodies that are remote from one another.

17. A separator according to claim 16 further comprising a divided dust collecting chamber connected to both of the dust outlets.

18. A separator according to claim 16 further comprising an air outlet member, having a portion extending into the first and the second cyclone bodies in opposite directions from the adjacent ends thereof.

19. A separator according to claim 18 wherein the air outlet member is a generally T-shaped pipe, with the oppositely-extending portions thereof connected to an outlet pipe lying between the adjacent ends of the first and second cyclone bodies.

20. A separator according to claim 19 wherein the outlet pipe extends transversely of the axes of the first and second cyclone bodies, for connection to a source of suction in a cleaner.

21. A separator according to claim 12, further comprising an air inlet member providing a branched passage leading to the air inlet passage of the first cyclone body and the air inlet passage of the second cyclone body.

22. A separator according to claim 17 wherein the first and second cyclone bodies and the dust collection chamber are connected to form a unit removeably connected to a suction cleaner body.
