Surface cleaning apparatus, cyclonic air treatment member and surface cleaning apparatus including the same
A surface cleaning apparatus comprises an air treatment chamber having a first end, an axially opposed second end, an axis extending between the first and second axially opposed ends and an axially extending air treatment chamber sidewall. The air treatment chamber air outlet is provided at the second opposed end and the first opposed end is moveably mounted between a closed position and an open position in which the air treatment chamber is open. The air treatment chamber has a stationary portion and an openable portion and the openable portion is moveably mounted between a closed position and an open position in which the air treatment chamber is open. When the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the air treatment chamber sidewall.
1. A vacuum cleaner comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) an air treatment assembly provided in the air flow path, the air treatment assembly comprising an air treatment chamber, the air treatment chamber comprising a cyclone having a first end having a first end wall, an axially opposed second end having a second end wall, a cyclone air inlet, a cyclone air outlet, a cyclone axis extending between the first and second axially opposed ends in an axial direction and a sidewall extending in the axial direction between the first and second axially opposed ends, wherein the cyclone air outlet is provided at the second opposed end and wherein the first opposed end is moveably mounted by a first opposed end mount between a closed position and an open position in which the air treatment chamber is open; and,
(c) a suction motor provided in the air flow path,
wherein the air treatment chamber has a stationary portion and an openable portion, the openable portion is moveably mounted by an openable portion mount between a closed position and an open position in which the air treatment chamber is open, and
wherein, when the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend along a length of the sidewall in the axial direction.
2. The vacuum cleaner of claim 1 wherein the second end wall is moveable with the openable portion.
3. The vacuum cleaner of claim 1 wherein the openable portion is generally U-shaped in a plane that is transverse to the cyclone axis.
4. The vacuum cleaner of claim 1 wherein the cyclone air outlet comprises a porous member that is mounted to the second end wall of the cyclone and the second end wall is part of the openable portion.
5. The vacuum cleaner of claim 4 wherein the second end wall is mounted in a fixed orientation with respect to the openable portion.
6. The vacuum cleaner of claim 1 wherein the openable portion mount is located adjacent the cyclone air outlet.
7. The vacuum cleaner of claim 1 wherein the openable portion mount comprises a rotational mount.
8. The vacuum cleaner of claim 7 wherein the openable portion mount is a pivot mount and the openable portion is pivotally mounted to vacuum cleaner adjacent an air outlet end of the cyclone.
9. The vacuum cleaner of claim 1 wherein the first end wall is moveable with the openable portion.
10. The vacuum cleaner of claim 9 wherein the first end wall is fixedly mounted to the openable portion.
11. The vacuum cleaner of claim 1 wherein the first end wall is openable independently of opening the openable portion.
12. The vacuum cleaner of claim 11 wherein the first end wall is movable mounted to the openable portion.
13. A vacuum cleaner comprising:
(a) an air flow path extending from a dirty air inlet to a clean air outlet;
(b) an air treatment assembly provided in the air flow path, the air treatment assembly comprising an air treatment chamber, the air treatment chamber comprising a cyclone having a first end having a first end wall, an axially opposed second end having a second end wall, a cyclone air inlet, a cyclone air outlet, a cyclone axis extending between the first and second axially opposed ends in an axial direction and a sidewall extending between the first and second axially opposed ends, wherein the cyclone air outlet is provided at the second opposed end and wherein the first opposed end is moveably mounted by a first opposed end mount between a closed position and an open position in which the cyclone is open; and,
(c) a suction motor provided in the air flow path,
wherein the air treatment chamber has a stationary portion and an openable portion, the openable portion is moveably mounted by an openable portion mount between a closed position and an open position in which the air treatment chamber is open, and
wherein the openable portion is U-shaped in a plane that is transverse to the cyclone axis.
14. The vacuum cleaner of claim 13 wherein, when the openable portion is in the closed position, the openable portion and the stationery portion abut along peripheral edges that extend generally in the axial direction axially along a length of the air treatment chamber sidewall.
15. The vacuum cleaner of claim 13 wherein the second end wall is moveable with the openable portion.
16. The vacuum cleaner of claim 13 wherein the cyclone air outlet comprises a porous member that is mounted to the second end wall of the cyclone and the porous member is rotatable concurrently with the openable portion.
17. The vacuum cleaner of claim 13 wherein the cyclone air outlet comprises a porous member that is mounted to the second end wall of the cyclone and the porous member is rotatable subsequent to the openable portion moving towards the open position.
