Abstract

A hand vacuum cleaner comprises a main body and a removably mounted air treatment member. The air treatment member has an air flow passage which comprises a handle for the air treatment member.

Claims

1. A hand vacuum cleaner having a front end, a rear end, 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; and

,

(b) an air treatment member, the air treatment member comprising an air treatment member axis and an air treatment member handle wherein the air treatment member handle comprises an air flow passage, wherein the air treatment member handle has an outward side spaced outwardly from the air treatment member, an inward side positioned between the air treatment member and the outward side of the air treatment member handle and a middle portion positioned between the outward side and the inward side, and the air treatment member handle narrows in a direction transverse to a direction of air flow through the handle from the middle portion towards the inward side.

2. The hand vacuum cleaner of claim 1 wherein the air flow passage comprises an inlet passage of the air treatment member.

3. The hand vacuum cleaner of claim 2 wherein the inlet passage extends longitudinally between a dirty air inlet end and an outlet end.

4. The hand vacuum cleaner of claim 1 wherein the air treatment member handle comprises a portion spaced from the air treatment member whereby a finger receiving area is provided between the air treatment member handle and the air treatment member.

5. The hand vacuum cleaner of claim 1 wherein the air treatment member handle is provided above the air treatment member.

6. The hand vacuum cleaner of claim 1 wherein the passage extends generally axially in the direction of the air treatment member axis.

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

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

9. The hand vacuum cleaner of claim 1 wherein the air treatment member is removable from the main body and the air treatment member handle is removable with the air treatment member.

10. The hand vacuum cleaner of claim 1, wherein a bleed valve is positioned in the air treatment member handle.

11. A hand vacuum cleaner having a front end, a rear end, 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; and

,

(b) a cyclone unit, the cyclone unit comprising a cyclone having a cyclone axis of rotation, a cyclone unit handle, wherein the cyclone unit handle comprises an air flow passage

wherein the cyclone unit handle comprises a portion spaced from the cyclone unit whereby a finger receiving area is provided between the cyclone unit handle and the cyclone unit.

12. The hand vacuum cleaner of claim 11 wherein the cyclone unit handle comprises an inlet passage of the cyclone unit.

13. The hand vacuum cleaner of claim 12 wherein the inlet passage extends longitudinally between a dirty air inlet end and an outlet end.

14. The hand vacuum cleaner of claim 11 wherein the cyclone unit handle is provided above the cyclone unit.

15. The hand vacuum cleaner of claim 11 wherein the passage extends generally parallel to the cyclone axis.

16. The hand vacuum cleaner of claim 11 wherein the driving handle comprises a portion spaced from the main body whereby a finger receiving area is provided between the driving handle and the main body.

17. The hand vacuum cleaner of claim 11 wherein the driving handle is provided at the rear end of the main body.

18. The hand vacuum cleaner of claim 11 wherein the cyclone unit is removable from the main body and the cyclone unit handle is removable with the cyclone unit.

19. The hand vacuum cleaner of claim 11 wherein when the hand vacuum cleaner is oriented with the upper end positioned above the lower end, the cyclone axis of rotation is generally horizontal.

20. The hand vacuum cleaner of claim 11, wherein a bleed valve is positioned in the cyclone unit handle.
