Abstract

A handheld vacuum cleaner including a housing having a front end, a back end, a first side, and a second side, the housing further including a handle along a handle axis the handle axis extends in a direction from the back end toward the front end. A suction nozzle is along a suction nozzle axis that extends in a direction from the front end toward the back end. The handheld vacuum further includes a suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust. The cyclonic separator includes a longitudinal axis that extends in a direction from the first side toward the second side and the handle axis and the suction nozzle axis intersect at an obtuse angle.

First claim

What is claimed is:

1. A handheld vacuum cleaner comprising:
a housing having a front end, a back end, a first side, and a second side, the housing further including;
a handle along a handle axis, wherein the handle axis extends in a direction from the back end toward the front end;
a suction nozzle along a suction nozzle axis, wherein the suction nozzle axis extends in a direction from the front end toward the back end; and
a suction source including a motor and a fan, the motor operable to rotate the fan about a motor axis, the suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through a cyclonic separator to a clean air exhaust, the cyclonic separator includes a longitudinal axis that extends in a direction from the first side toward the second side; and
wherein the handle axis and the suction nozzle axis intersect at an obtuse angle.

2. The handheld vacuum cleaner of claim 1 , wherein the motor axis extends in a direction from the first side toward the second side.

3. The handheld vacuum cleaner of claim 1 , wherein the cyclonic separator is adjacent to the motor in a generally side-by-side arrangement.

4. The handheld vacuum cleaner of claim 1 , wherein the cyclonic separator is located between the motor and the suction nozzle.

5. The handheld vacuum cleaner of claim 1 , wherein handle axis and the suction nozzle axis are generally perpendicular to the longitudinal axis of the cyclonic separator.

6. The handheld vacuum cleaner of claim 1 , wherein the handle axis and the suction nozzle axis intersect at an obtuse angle above the cyclonic separator.

7. The handheld vacuum of claim 1 , wherein the motor axis is generally parallel to the longitudinal axis of the cyclonic separator.

8. The handheld vacuum cleaner of claim 1 , wherein the cyclonic separator further comprises:
a cylindrical wall having a first end and a second end,
a first end wall located at the first end of the cylindrical wall,
a dirty air inlet,
a clean air inlet,
a debris outlet adjacent the second end of the cylindrical wall, and
a debris collection chamber located within the housing and in fluid communication with the debris outlet of the cyclonic separator;
wherein the housing includes an aperture that extends through the first side, and wherein the first end wall of the cyclonic separator is removable through the aperture of the first side of the housing.

9. The handheld vacuum cleaner of claim 8 , wherein the dirty air inlet is adjacent the first end of the cylindrical wall.

10. The handheld vacuum cleaner of claim 8 , wherein the dirty air inlet extends through the cylindrical wall.

11. The handheld vacuum cleaner of claim 8 , wherein the clean air outlet is adjacent the first end of the cylindrical wall.

12. The handheld vacuum cleaner of claim 11 , further comprising a perforated tube located within the cylindrical wall.

13. The handheld vacuum cleaner of claim 8 , wherein the clean air outlet extends through the first end wall of the cyclonic separator.

14. The handheld vacuum cleaner of claim 13 , wherein the second side of the housing forms a second end wall of the cyclonic separator located at the second end of the cylindrical wall.

15. The handheld vacuum cleaner of claim 14 , wherein the debris outlet is adjacent the second end wall and the second end wall defines a portion of the debris outlet.

16. The handheld vacuum cleaner of claim 15 , wherein at least a portion of the first end wall is removable from the cylindrical wall.

17. The handheld vacuum cleaner of claim 16 , further comprising a perforated tube located within the cylindrical wall, the perforated tube extending from the first end wall of the cyclonic separator forming the clean air outlet, and wherein the perforated tube is removable with the first end wall through the aperture of the first side of the housing.

18. The handheld vacuum cleaner of claim 16 , wherein the suction source is located within the housing, the handheld vacuum cleaner further comprising a door coupled to the first side of the housing, the door movable relative to the housing to permit access to a filter chamber on or adjacent the first side of the housing.

19. The handheld vacuum cleaner of claim 18 , further comprising an airflow passageway along the first side of the housing from the clean air outlet to the filter chamber.

20. The handheld vacuum cleaner of claim 18 , wherein the door defines a duct that provides fluid communication between the cyclonic separator and the suction source.

21. The handheld vacuum cleaner of claim 8 , wherein the suction sources is located within the housing, the handheld vacuum cleaner further comprising a door coupled to the first side of the housing, the door movable relative to the housing to permit access to a filter chamber on or adjacent the first side of the housing.

22. The handheld vacuum cleaner of claim 21 , further comprising a premotor filter in the filter chamber configured to filter debris in the airflow traveling from the cyclonic separator to the suction source, the door movable relative to the housing to permit access to the premotor filter.

23. The handheld vacuum cleaner of claim 8 , further comprising a debris collection chamber door removably coupled to the housing to facilitate emptying debris from the debris collection chamber.

24. A handheld vacuum cleaner comprising:
a housing having a front end, a back end, a top side, a bottom side, a first side, and a second side;
a handle located at the top side of the housing, the handle having a longitudinal axis that extends in a direction from the back end toward the front end;
a suction nozzle located at the front end of the housing, the suction nozzle extends in a direction from the front end toward the back end that intersects the longitudinal axis of the handle;
a cyclonic separator having a longitudinal axis that extends in a direction from the first side toward the second side;
a clean air exhaust; and
a suction source including a motor and a fan, the motor operable to rotate the fan about a motor axis, the suction source operable to generate an airflow through the vacuum cleaner from the suction nozzle through the cyclonic separator to rotate the airflow about the longitudinal axis of the cyclonic separator and to the clean air exhaust.

25. The handheld vacuum cleaner of claim 24 , wherein the suction nozzle includes an opening that faces toward the bottom side of the housing and away from the longitudinal axis of the handle.

26. The handheld vacuum cleaner of claim 24 , wherein the motor axis and the longitudinal axis of the cyclonic separator are between the bottom side of the housing and the longitudinal axis of the handle.

27. The handheld vacuum cleaner of claim 26 , wherein the motor axis extends in a direction from the first side toward the second side parallel to the longitudinal axis of the cyclonic separator.
