Abstract

A hand vacuum cleaner has a cyclone chamber formed of at least two axially extending cyclone chamber sidewall portions wherein one of the portions is pivotally openable. Once opened, a moveable member is translatable to clean or enable cleaning of a screen.

First claim

The invention claimed is:

1. A hand vacuum cleaner comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) a main body having the dirty air inlet, a suction motor positioned in the air flow path upstream of the clean air outlet and a handle;
(c) a cyclone positioned in the air flow path, the cyclone comprising a cyclone chamber, a cyclone chamber air inlet, a cyclone chamber air outlet, a centrally positioned cyclone axis of rotation, a first end having the cyclone chamber air outlet, an axially spaced apart second end and an axially extending sidewall extending between the first and second ends, wherein the cyclone chamber air outlet comprises a generally axially extending porous member having a porous sidewall and wherein a portion of the axially extending sidewall is rotatably mounted between a closed position in which the cyclone chamber is closed and an open position in which the cyclone chamber is open; and,
(d) a moveable member comprising at least one of the portion of the axially extending sidewall, the porous member and, a cleaning member positioned in the cyclone chamber between the axially extending sidewall of the cyclone chamber and the porous sidewall, wherein the moveable member is moveable from an operating position in which the moveable member is positioned towards the first end and a cleaning position in which the moveable member has been translated axially away from the first end,
wherein, the moveable member is moveable as or subsequent to the portion of the axially extending sidewall of the cyclone chamber being moved away from the closed position.

2. The hand vacuum cleaner of claim 1 , wherein the moveable member is moveable from the operating position towards the cleaning position as the portion of the axially extending sidewall of the cyclone chamber is moved from the closed position towards the open position.

3. The hand vacuum cleaner of claim 2 , wherein the moveable member is biased towards the cleaning position.

4. The hand vacuum cleaner of claim 1 , wherein the moveable member is moveable from the operating position to the cleaning position when the portion of the axially extending sidewall of the cyclone chamber is in the open position.

5. The hand vacuum cleaner of claim 4 further comprising an actuator that is drivingly connected to the moveable member.

6. The hand vacuum cleaner of claim 1 wherein the portion of the axially extending sidewall is rotatably mounted by a rotatable mount and the rotatable mount is located at the first end of the cyclone.

7. The hand vacuum cleaner of claim 6 , wherein the portion of the axially extending sidewall is pivotally mounted to the main body about an axis that is transverse to the cyclone axis of rotation.

8. The hand vacuum cleaner of claim 1 , wherein the moveable member comprises at least one of the portion of the axially extending sidewall and the cleaning member, and in the cleaning position, at least a portion of the moveable member is positioned axially outwardly of the first end of the cyclone.

9. The hand vacuum cleaner of claim 8 , wherein the moveable member is telescopically mounted.

10. The surface cleaning apparatus of claim 1 wherein the moveable member comprises the cleaning member wherein, in the operating position, the cleaning member abuts the first end and, in the cleaning position, at least a portion of the cleaning member has been translated axially away from the first end.

11. The surface cleaning apparatus of claim 10 wherein the cleaning member comprises an annular member.

12. The hand vacuum cleaner of claim 1 wherein the moveable member comprises the porous member and in the cleaning position, the porous member has been axially translated away from the first end.

13. The hand vacuum cleaner of claim 12 wherein, in the cleaning position, at least a portion of the porous member is positioned axially outwardly of the first end of the cyclone.

14. The hand vacuum cleaner of claim 1 wherein the moveable member comprises the portion of the axially extending sidewall and the cleaning member.

15. The hand vacuum cleaner of claim 1 wherein the moveable member comprises the portion of the axially extending sidewall.

16. The surface cleaning apparatus of claim 1 wherein the porous member is tapered towards the second end.

17. A hand vacuum cleaner 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 member comprising an air treatment chamber, an air treatment chamber air inlet, an air treatment chamber air outlet, a first end having the air treatment chamber air outlet, a second end longitudinally spaced apart in a longitudinal direction 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 upstream of the clean air outlet;
(d) a moveable member positioned in the air treatment chamber, the moveable member comprising at least one of a portion of the air treatment member sidewall, the porous member and a cleaning member positioned in the air treatment chamber between the air treatment chamber sidewall and the porous sidewall; and,
wherein, the moveable member is moveable as or subsequent to the portion of the air treatment member sidewall being moved away from the closed position, and
the moveable member comprises at least one of the portion of the air treatment member sidewall and the cleaning member, and in the cleaning position, at least a portion of the moveable member is positioned longitudinally outwardly from the second end of the air treatment member.

18. The hand vacuum cleaner of claim 17 wherein the moveable member is telescopically mounted.

19. A hand vacuum cleaner 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 member comprising an air treatment chamber, an air treatment chamber air inlet, an air treatment chamber air outlet, a first end having the air treatment chamber air outlet, a second end longitudinally spaced apart in a longitudinal direction 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 upstream of the clean air outlet;
(d) a moveable member positioned in the air treatment chamber, the moveable member comprising at least one of a portion of the air treatment member sidewall, the porous member and a cleaning member positioned in the air treatment chamber between the air treatment chamber sidewall and the porous sidewall; and,
wherein, the moveable member is moveable as or subsequent to the portion of the air treatment member sidewall being moved away from the closed position, and
wherein the portion of the air treatment member sidewall is pivotally mounted about an axis that is transverse to the longitudinal direction.
