Abstract

A cyclonic air treatment member comprises a cyclone and a dirt collection chamber external to the cyclone chamber. The cyclone chamber extends longitudinally in an axial direction between a cyclone first end and a cyclone second end. The cyclone chamber includes an axially extending dirt outlet. A removable dirt outlet insert member may be removably receivable by a portion of the dirt outlet.

Claims (21)

  1. CLAIMS:
    1 . A cyclonic air treatment member comprising: (a) a cyclone having a cyclone sidewall, a cyclone first end, an opposed cyclone second end, a cyclone air inlet proximate the cyclone first end, a cyclone air outlet and a cyclone longitudinal axis extending from the cyclone first end to the cyclone second end, wherein a cyclone chamber is located between the cyclone first and second ends and the cyclone chamber has an outer perimeter which comprises the cyclone sidewall, wherein an air flow path extends from the cyclone air inlet to the cyclone air outlet: and, (b) a dirt collection chamber external to the cyclone chamber, the dirt collection chamber having first and second dirt outlet regions, each dirt outlet region extending around a portion of the perimeter of the cyclone chamber, wherein the second dirt outlet region is positioned proximate the cyclone second end, and the first dirt outlet region is positioned toward the cyclone first end relative to the second dirt outlet region.
  2. 2. The cyclonic air treatment member of claim 1 , wherein the first dirt outlet region is longitudinally spaced apart from and discrete from the second dirt outlet region.
  3. 3. The cyclonic air treatment member of claim 1 , wherein the second dirt outlet region is longitudinally spaced apart from and contiguous with the first dirt outlet region.
  4. 4. The cyclonic air treatment member of claim 1 , wherein the first dirt outlet region is angularly offset about the outer perimeter of the cyclone chamber as compared to the second dirt outlet region.
  5. 5. The cyclonic air treatment member of claim 1 , wherein at least one of the first and second dirt outlet regions comprises a slot extending angularly around a portion of the perimeter of the cyclone chamber.
  6. 6. The cyclonic air treatment member of claim 1 , wherein at least one of the first and second dirt outlet regions comprises an array of 4 or more apertures formed in the cyclone sidewall.
  7. 7. The cyclonic air treatment member of claim 1 , wherein the first dirt outlet region comprises a slot formed in the cyclone sidewall, and the second dirt outlet region comprises an array of 4 or more apertures formed in the cyclone sidewall and positioned adjacent the first dirt outlet region between the cyclone first end and the first dirt outlet region.
  8. 8. The cyclonic air treatment member of claim 1 , wherein each of the first and second dirt outlet regions has a long dimension, and the long dimension of the first dirt outlet region is oriented generally transverse to the long dimension of the second dirt outlet region.
  9. 9. The cyclonic air treatment member of claim 1 , wherein the air flow path includes a cyclonic path portion that extends cyclonically from the cyclone air inlet toward the cyclone second end, and at least one of the dirt outlet regions has a long dimension that is aligned with the cyclonic path portion.
  10. 10. The cyclonic air treatment member of claim 9, wherein at least 75% of the first dirt outlet extends along a portion of the cyclonic path portion.
  11. 11. The cyclonic air treatment member of claim 9, wherein the first dirt outlet region extends along the cyclonic path from an upstream outlet end of the first dirt outlet region to a downstream outlet end of the first dirt outlet region.
  12. 12. The cyclonic air treatment member of claim 1 1 , wherein the downstream outlet end of the first dirt outlet region is positioned towards the cyclone second end relative to the upstream outlet end of the first dirt outlet region.
  13. 13. The cyclonic air treatment member of claim 1 1 , wherein both of the upstream outlet end of the first dirt outlet region and the downstream outlet end of the first dirt outlet region are located along a portion of the cyclonic path portion.
  14. 14. The cyclonic air treatment member of claim 1 , wherein the second dirt outlet region has a long dimension having a radial projection that is aligned perpendicularly to the cyclone axis.
  15. 15. The cyclonic air treatment member of claim 14, wherein the first dirt outlet region has a long dimension having a radial projection that is aligned parallel to the cyclone axis.
  16. 16. The cyclonic air treatment member of claim 1 , wherein the second dirt outlet region is bordered by the cyclone second end.
  17. 17. The cyclonic air treatment member of claim 1 , wherein the cyclone further comprises a third dirt outlet region to the dirt collection chamber, the third dirt outlet region is formed in the cyclone sidewall, and is oriented transverse to the first and second dirt outlet regions.
  18. 18. The cyclonic air treatment member of claim 17, wherein the first, second, and third dirt outlet regions are contiguous .
  19. 19. The cyclonic air treatment member of claim 17, wherein the first, second, and third dirt outlet regions are discrete.
  20. 20. The cyclonic air treatment member of claim 1 , wherein the cyclone air outlet is at the cyclone second end.
  21. 21. The cyclonic air treatment member of claim 1 , wherein the cyclone air outlet is at the cyclone first end.
