Surface cleaning apparatus, cyclonic air treatment member and surface cleaning apparatus including the same
A surface cleaning apparatus comprises an air treatment member having an air treatment chamber. A moveable member is positioned in the air treatment chamber. A driving assembly is drivingly connected to the moveable member wherein an end wall of the air treatment chamber is openable in response to the moveable member being longitudinally translated through at least the portion of the air treatment chamber.
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 and a longitudinally extending sidewall, wherein the air treatment chamber air outlet comprises a longitudinally extending porous member having a porous sidewall;
(c) a suction motor positioned in the air flow path upstream of the clean air outlet;
(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, 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; and,
(e) a handle drivingly connected to the moveable member whereby operation of the handle translates the moveable member longitudinally through at least a portion of the chamber,
wherein the first end is moved from a closed position to an open position when the moveable member is longitudinally translated through at least the portion of the chamber.
2. The vacuum cleaner or extractor of claim 1 further comprising an openable lock operable between a locked position in which the first end is secured in a closed position and an open position in which the first end is moveable to an open position, and the lock is moveable from the locked position to the open position in response to the moveable member being longitudinally translatable through at least the portion of the chamber.
3. The vacuum cleaner or extractor of claim 2 wherein the driving linkage operably engages the lock to move the lock from the locked position to the open position as the moveable member is longitudinally translated through at least the portion of the chamber.
4. The vacuum cleaner or extractor of claim 3 wherein the driving linkage comprises a longitudinally extending drive rod.
5. The vacuum cleaner or extractor of claim 4 wherein the driving linkage operably engages the first end to open the first end as the moveable member is longitudinally translated through the chamber.
6. The vacuum cleaner or extractor of claim 3 wherein the driving linkage operably engages the first end to open the first end as the moveable member is longitudinally translated through at least the portion of the chamber.
7. The vacuum cleaner or extractor of claim 3 wherein the moveable member comprises the cleaning member and the cleaning member operably engages the first end to open the first end as the cleaning member is longitudinally translated through at least the portion of the chamber.
8. The vacuum cleaner or extractor of claim 3 wherein the moveable member comprises the porous member and the porous member operably engages the first end to open the first end as the porous member is longitudinally translated through at least the portion of the chamber.
9. The vacuum cleaner or extractor of claim 2 wherein the moveable member comprises the cleaning member and the cleaning member operably engages the lock to move the lock from the locked position to the open position as the cleaning member is longitudinally translated through at least the portion of the chamber.
10. The vacuum cleaner or extractor of claim 9 wherein the cleaning member operably engages the first end to open the first end as the cleaning member is longitudinally translated through at least the portion of the chamber.
11. The vacuum cleaner or extractor of claim 2 wherein the moveable member comprises the porous member and the porous member operably engages the lock to move the lock from the locked position to the open position as the porous member is longitudinally translated through at least the portion of the chamber.
12. The vacuum cleaner or extractor of claim 11 wherein the porous member operably engages the first end to open the first end as the porous member is longitudinally translated through at least the portion of the chamber.
13. The vacuum cleaner or extractor of claim 1 wherein, in the cleaned position, at least a portion of the moveable member is exterior of the air treatment chamber.
14. 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.
15. The vacuum cleaner or extractor of claim 1 wherein the cleaning member comprises an annular member.
16. The vacuum cleaner or extractor of claim 15 wherein the annular member has a plurality of finger members depending longitudinally therefrom.
17. The vacuum cleaner or extractor of claim 16 wherein the finger members depend from a radially outward portion of the annular member.
18. The vacuum cleaner or extractor of claim 1 wherein the air treatment member comprises a cyclone having a centrally positioned cyclone axis of rotation.
19. The vacuum cleaner or extractor of claim 1 wherein the porous member is tapered towards the openable first end.
