Abstract

A surface cleaning apparatus comprises an air treatment chamber with a moveable member positioned therein. An end wall of the air treatment chamber is openable in response to a moveable member being longitudinally translated through at least the portion of the air treatment chamber. The driving assembly includes a handle and a drive rod that is rotatably mounted about a longitudinally extending axis of the drive rod between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber. In the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber and, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.

First claim

The invention claimed is:

1. A vacuum cleaner or extractor comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) an air treatment member having an air treatment chamber positioned in the air flow path, the air treatment chamber comprising an air treatment chamber air inlet, an air treatment chamber air outlet, an openable first end, a longitudinally spaced apart second end having the air treatment chamber air outlet and a longitudinally extending sidewall, wherein the air treatment chamber air outlet comprises a longitudinally extending porous member having a longitudinally extending porous sidewall;
(c) a suction motor positioned in the air flow path;
(d) a moveable member positioned in the air treatment chamber, the moveable member comprising at least one of the porous member and a cleaning member positioned in the air treatment chamber between the sidewall of the air treatment chamber and the porous sidewall; and,
(e) a driving assembly comprising a handle and a driving linkage, the driving linkage comprises a longitudinally extending drive rod having a longitudinally extending axis, the drive rod is rotatably mounted about the longitudinally extending axis between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber, wherein, in the stored position, the handle is longitudinally spaced from the first and second ends of the air treatment chamber, whereby, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.

2. The vacuum cleaner or extractor of claim 1 wherein the driving linkage comprises an extendable member wherein, in the stored position, the extendable member is in a contracted configuration and, in the operable position, the extendable member is in an extended configuration in which the handle is operable to longitudinally translate the moveable member through at least a portion of the chamber.

3. The vacuum cleaner or extractor of claim 2 wherein the extendable member comprises a telescoping drive rod.

4. The vacuum cleaner or extractor of claim 1 wherein a portion of the driving linkage is exterior to the air treatment chamber and in the stored position, the portion of the driving linkage is recessed against a portion of the vacuum cleaner or extractor.

5. The vacuum cleaner or extractor of claim 4 wherein, in the stored position, the portion of the driving linkage is coextensive with the portion fimof the air treatment member.

6. The vacuum cleaner or extractor of claim 2 wherein the extendable member is exterior to the air treatment chamber and in the contracted configuration, the extendable member is recessed against a portion of the vacuum cleaner or extractor.

7. The vacuum cleaner or extractor of claim 6 wherein, in the contracted configuration, the extendable member is coextensive with a portion of the air treatment member.

8. The vacuum cleaner or extractor of claim 1 wherein, in the stored position, a flange that extends from an outer surface of a portion of the vacuum cleaner or extractor impedes the handle translating the moveable member through at least a portion of the chamber and in the operable position the handle is rotated away from the flange.

9. The vacuum cleaner or extractor of claim 8 wherein, in the stored position, the handle abuts the flange.

10. The vacuum cleaner or extractor of claim 1 further comprising a stop member operably engageable with the driving assembly to inhibit the driving assembly moving to the operable position wherein the step member comprises an abutment surface that is part of an exterior surface of the vacuum cleaner or extractor.

11. The vacuum cleaner or extractor of claim 1 wherein the moveable member is moveable from an operating position in which the moveable member is positioned towards the second end and a cleaned position in which the moveable member is translated longitudinally away from the second end.

12. The vacuum cleaner or extractor of claim 11 wherein in the cleaned position, at least a portion of the moveable member is exterior of the air treatment chamber.

13. The vacuum cleaner or extractor of claim 1 wherein the moveable member comprises the cleaning member and the cleaning member is moveable from an operating position in which the cleaning member abuts the second end and a cleaned position in which the moveable member is translated longitudinally away from the second end.

14. The vacuum cleaner or extractor of claim 1 wherein the cleaning member comprises an annular member.

15. A vacuum cleaner or extractor comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) an air treatment member having an air treatment chamber positioned in the air flow path, the air treatment chamber comprising an air treatment chamber air inlet, an air treatment chamber air outlet, an openable first end, a longitudinally spaced apart second end having the air treatment chamber air outlet and a longitudinally extending sidewall, wherein the air treatment chamber air outlet comprises a longitudinally extending porous member having a longitudinally extending porous sidewall;
(c) a suction motor positioned in the air flow path;
(d) a moveable member positioned in the air treatment chamber, the moveable member comprising at least one of the porous member and a cleaning member positioned in the air treatment chamber between the sidewall of the air treatment chamber and the porous sidewall; and,
(e) a driving assembly comprising a handle and a driving linkage, the driving linkage comprises a longitudinally extending drive rod having a longitudinally extending axis, the drive rod is rotatably mounted about the longitudinally extending axis between a stored position in which the moveable member is in a stored position and an operable position in which the moveable member is translatable through at least a portion of the chamber, wherein, in the stored position, a flange that extends from an outer surface of a portion of the vacuum cleaner or extractor impedes the handle translating the moveable member through at least a portion of the chamber and in the operable position the handle is rotated away from the flange, whereby, when the driving assembly is in the operable position, the driving assembly is operable to longitudinally translate the moveable member through at least a portion of the chamber.

16. The vacuum cleaner or extractor of claim 15 wherein the driving linkage comprises an extendable member wherein, in the stored position, the extendable member is in a contracted configuration and, in the operable position, the extendable member is in an extended configuration in which the handle is operable to longitudinally translate the moveable member through at least a portion of the chamber.

17. The vacuum cleaner or extractor of claim 15 wherein a portion of the driving linkage is exterior to the air treatment chamber and in the stored position, the portion of the driving linkage is recessed against a portion of the vacuum cleaner or extractor.

18. The vacuum cleaner or extractor of claim 15 wherein, in the stored position, the handle abuts the flange.

19. The vacuum cleaner or extractor of claim 15 wherein the moveable member is moveable from an operating position in which the moveable member is positioned towards the second end and a cleaned position in
