Abstract

A hand vacuum cleaner comprises a main body has a driving handle and houses a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end. An air treatment member has a dirt collection region having an openable door provided on a front end of the air treatment member.

Claims

1. A hand vacuum cleaner having a front end having a dirty air inlet, a rear end, a clean air outlet, an upper end and a bottom, the hand vacuum cleaner comprising:

(a) a main body comprising an upper end, a lower end, a front end, a rear end and a driving handle, the main body housing a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end; and

,

(b) an air treatment member comprising a dirt collection region having an openable door provided on a front end of the air treatment member and an openable door lock comprising a door release actuator wherein the door is moveable to an open position when the door release actuator is actuated.

2. The hand vacuum cleaner of claim 1 wherein the hand grip portion is spaced from the main body whereby a finger receiving area is provided between the hand grip portion and the main body.

3. The hand vacuum cleaner of claim 2 wherein at least a portion of the finger receiving area is positioned linearly rearwardly from the air treatment member.

4. The hand vacuum cleaner of claim 1 wherein the main body comprises a suction motor housing and the driving handle has an end that extends from the suction motor housing.

5. The hand vacuum cleaner of claim 1 wherein the main body comprises a suction motor housing and the driving handle has an end that extends upwardly and forwardly from the suction motor housing.

6. The hand vacuum cleaner of claim 1 wherein the driving handle is provided at the rear end of the main body.

7. The hand vacuum cleaner of claim 1 wherein the inlet passage extends generally rearwardly.

8. The hand vacuum cleaner of claim 7 wherein the inlet passage is positioned above the openable door.

9. The hand vacuum cleaner of claim 7 wherein the dirty air inlet comprises an inlet passage that extends longitudinally between an inlet end and an outlet end and has a longitudinal passage axis and the longitudinal passage axis interests the driving handle.

10. The hand vacuum cleaner of claim 1 wherein the air treatment member has a front end having an air treatment member air inlet and a longitudinally rearwardly spaced apart rear end having an air treatment member air outlet.

11. The hand vacuum cleaner of claim 10 wherein the inlet passage is positioned above the openable door.

12. A hand vacuum cleaner having a front end having a dirty air inlet, a rear end, a clean air outlet, an upper end and a bottom, the hand vacuum cleaner comprising:

(a) a main body comprising an upper end, a lower end, a front end, a rear end and a driving handle, the main body housing a suction motor and fan assembly, the suction motor and fan assembly having a suction motor axis of rotation wherein the driving handle has a hand grip portion that extends upwardly and forwardly when the hand vacuum cleaner is oriented with the upper end above the lower end; and

,

(b) a cyclone unit comprising a cyclone having a cyclone axis of rotation, a dirt collection region having an openable door provided on a front end of the cyclone unit and an openable door lock comprising a door release actuator wherein the door is moveable to an open position when the actuator is actuated.

13. The hand vacuum cleaner of claim 12 wherein the hand grip portion is spaced from the main body whereby a finger receiving area is provided between the hand grip portion and the main body.

14. The hand vacuum cleaner of claim 12 wherein at least a portion of the finger receiving area is positioned linearly rearwardly from the cyclone unit.

15. The hand vacuum cleaner of claim 12 wherein the main body comprises a suction motor housing and the driving handle has an end that extends from the suction motor housing.

16. The hand vacuum cleaner of claim 12 wherein the main body comprises a suction motor housing and the driving handle has an end that extends upwardly and forwardly from the suction motor housing.

17. The hand vacuum cleaner of claim 12 wherein the driving handle is provided at the rear end of the main body.

18. The hand vacuum cleaner of claim 12 wherein the inlet passage extends generally rearwardly.

19. The hand vacuum cleaner of claim 18 wherein the inlet passage is positioned above the openable door.

20. The hand vacuum cleaner of claim 12 wherein the dirty air inlet comprises an inlet passage that extends longitudinally between an inlet end and an outlet end and has a longitudinal passage axis and the longitudinal passage axis interests the driving handle.

21. The hand vacuum cleaner of claim 20 wherein the inlet passage is positioned above the openable door.

22. The hand vacuum cleaner of claim 12 wherein when the hand vacuum cleaner is oriented with the upper end above the lower end, the cyclone axis of rotation is generally horizontal.
