Abstract

A vacuum cleaner operable to separate debris from an airflow including a separator defining a cyclonic chamber having a longitudinal axis, a dirty air inlet, a dirt outlet, and an air outlet. The vacuum cleaner further includes a dirt collection chamber in fluid communication with the dirt outlet of the cyclonic chamber. The longitudinal axis of the cyclonic chamber is oriented generally horizontally when the separator is received within the dirt collection chamber.

Claims

1. A vacuum cleaner operable to separate debris from an airflow, the vacuum cleaner comprising:

a first stage separator having a cylindrical outer sidewall defining a cyclonic chamber, the cyclonic chamber having a dirty air inlet, a dirt outlet, and an air outlet; and

a dirt collection chamber in fluid communication with the dirt outlet of the cyclonic chamber, the dirt collection chamber further including a bottom wall and a sidewall that extends upwardly from the bottom wall, the sidewall having an opening,

wherein the first stage separator, including the cylindrical outer sidewall, is removably and slidably received within the dirt collection chamber by inserting the separator into the opening of the sidewall, wherein the first stage separator, including the cylindrical outer wall, is removable from within the dirt collection chamber.

2. The vacuum cleaner of claim 1, wherein the separator further includes one of either a groove and a rail, and the dirt collection chamber further includes the other of either the groove and the rail.

3. The vacuum cleaner of claim 2, wherein the separator includes two grooves and the dirt collection chamber includes two rails.

4. The vacuum cleaner of claim 3, wherein the two grooves extend along a length of the cyclonic chamber.

5. The vacuum cleaner of claim 4, wherein the two grooves are spaced approximately 180 degrees apart.

6. The vacuum cleaner of claim 1, wherein the separator is configured for generally horizontal insertion into the dirt collection chamber.

7. The vacuum cleaner of claim 1, wherein the dirty air inlet is formed in a first end of the cyclonic chamber and the dirt outlet is formed in a second end of the cyclonic chamber.

8. The vacuum cleaner of claim 7, wherein the air outlet is formed in the first end of the cyclonic chamber.

9. The vacuum cleaner of claim 7, wherein the second end of the cyclonic chamber abuts a front wall of the dirt collection chamber.

10. The vacuum cleaner of claim 1, wherein the separator further includes a top cover that, when assembled in the dirt collection chamber, defines an outer periphery of the dirt collection chamber.

11. The vacuum cleaner of claim 10, wherein a rib extends between the top cover and the cyclonic chamber.

12. The vacuum cleaner of claim 10, wherein the dirty air inlet extends through the top cover.

13. The vacuum cleaner of claim 1, wherein the separator further includes a back cover that, when assembled in the dirt collection chamber, defines an outer periphery of the dirt collection chamber.

14. The vacuum cleaner of claim 13, wherein the air outlet extends through the back cover.

15. The vacuum cleaner of claim 1, wherein a baffle tube is coupled to the air outlet.

24. The vacuum cleaner of claim 1, further comprising a top wall opposite the bottom wall, wherein the sidewall extends between the top wall and the bottom wall.

25. The vacuum cleaner of claim 24, wherein the top wall is removable from the dirt collection chamber with the first stage separator.

26. The vacuum cleaner of claim 1, wherein the dirt collection chamber includes a door that is opened to allow the dirt collection chamber to be emptied, wherein the door defines at least a portion of the bottom wall.

16. A vacuum cleaner operable to separate debris from an airflow, the vacuum cleaner comprising:

a first stage separator having a cylindrical outer sidewall defining a cyclonic chamber, the cyclonic chamber having a longitudinal axis, a dirty air inlet, a dirt outlet, and an air outlet; and

a dirt collection chamber in fluid communication with the dirt outlet of the cyclonic chamber,

wherein the first stage separator, including the cylindrical outer sidewall, is removably received within the dirt collection chamber along a generally horizontal direction, and wherein the longitudinal axis of the cyclonic chamber is oriented generally horizontally when the separator is received within the dirt collection chamber.

17. The vacuum cleaner of claim 16, wherein the dirt outlet is oriented such that dirt exiting the cyclonic chamber travels vertically into the dirt collection chamber.

18. The vacuum cleaner of claim 16, wherein the dirty air inlet is formed in a first end of the cyclonic chamber and a front wall of the dirt collection chamber abuts a second end of the cyclonic chamber.

19. The vacuum cleaner of claim 18, wherein the dirt outlet is formed in the second end of the cyclonic chamber.

20. The vacuum cleaner of claim 16, wherein the separator is removably received within the dirt collection chamber with a groove and a rail arrangement.

21. The vacuum cleaner of claim 16, wherein the separator further includes a top cover that, when assembled in the dirt collection chamber, defines an outer periphery of the dirt collection chamber.

22. The vacuum cleaner of claim 16, wherein the separator further includes a back cover that, when assembled in the dirt collection chamber, defines an outer periphery of the dirt collection chamber.

23. The vacuum cleaner of claim 16, wherein the dirt collection chamber includes a pivotably openable door.

27. The vacuum cleaner of claim 16, further comprising a top wall opposite the bottom wall, wherein the sidewall extends between the top wall and the bottom wall.

28. The vacuum cleaner of claim 27, wherein the top wall is removable from the dirt collection chamber with the first stage separator.

29. The vacuum cleaner of claim 16, wherein the dirt collection chamber includes a door that is opened to allow the dirt collection chamber to be emptied, wherein the door defines at least a portion of the bottom wall.
