Abstract

A hand vacuum cleaner may include a suction motor and fan assembly that is positioned downstream of a pre-motor filter. A post motor filter may be positioned downstream of the suction motor and fan assembly and may be in the lower end of the hand vacuum cleaner and an energy storage member may be in an upper end of the handle.

First claim

The invention claimed is:

1. A hand vacuum cleaner having a front end, a rear end, an upper end, a lower end and a handle, the hand vacuum cleaner comprising:
(a) an air flow passage extending from an air inlet to a clean air outlet;
(b) an air treatment member downstream of the air inlet;
(c) a suction motor and fan assembly that is positioned in the air flow passage;
(d) at least one energy storage member positioned at an upper end of the handle; and,
(e) a post motor filter positioned downstream of the suction motor and fan assembly and at a lower end of the handle.

2. The hand vacuum cleaner of claim 1 wherein the handle has a hand grip portion that extends upwardly and forwardly, the at least one energy storage member is positioned at an upper end of the hand grip portion and the post motor filter positioned at a lower end of the hand grip portion.

3. The hand vacuum cleaner of claim 1 wherein the suction motor and fan assembly is positioned forward of at least some of the energy storage members.

4. The hand vacuum cleaner of claim 1 wherein the suction motor and fan assembly is positioned forward of all of the energy storage members.

5. The hand vacuum cleaner of claim 1 wherein the suction motor and fan assembly is positioned rearward of the air treatment member.

6. The hand vacuum cleaner of claim 1 wherein the air treatment member comprises a cyclone chamber and the suction motor and fan assembly is positioned rearward of the cyclone chamber.

7. The hand vacuum cleaner of claim 6 wherein the cyclone chamber has an axis of rotation and the suction motor is positioned below the axis of rotation.

8. The hand vacuum cleaner of claim 7 wherein the axis of rotation extends in a forward/rearward direction.

9. The hand vacuum cleaner of claim 8 wherein air travels rearwardly from the suction motor to the post-motor filter.

10. The hand vacuum cleaner of claim 9 wherein air travels generally linearly from the suction motor to the post-motor filter.

11. The hand vacuum cleaner of claim 9 wherein the suction motor and fan assembly is positioned forward of at least some of the energy storage members.

12. The hand vacuum cleaner of claim 1 wherein the air treatment member comprises a cyclone chamber which has an axis of rotation and the suction motor is positioned below the axis of rotation.

13. The hand vacuum cleaner of claim 12 wherein the axis of rotation extends in a forward/rearward direction.

14. The hand vacuum cleaner of claim 13 wherein air travels rearwardly from the suction motor to the post-motor filter.

15. The hand vacuum cleaner of claim 14 wherein air travels generally linearly from the suction motor to the post-motor filter.

16. The hand vacuum cleaner of claim 15 wherein the suction motor and fan assembly is positioned forward of at least some of the energy storage members.

17. The hand vacuum cleaner of claim 1 wherein air travels rearwardly from the suction motor to the post-motor filter.

18. The hand vacuum cleaner of claim 17 wherein air travels generally linearly from the suction motor to the post-motor filter.

19. The hand vacuum cleaner of claim 17 wherein the suction motor and fan assembly is positioned forward of at least some of the energy storage members.
