Abstract

An all in the head surface cleaning apparatus may include a surface cleaning head having a dirty air inlet and first and second laterally opposed sidewalls. The surface cleaning head may include a brush motor drivingly connected to a moveable brushing member, the brush motor having a brush motor axis. The surface cleaning head may include a cyclone assembly having a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber and positioned forward or rearward of the cyclone chamber. The cyclone may have a longitudinal cyclone axis. The surface cleaning head may include a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends. An upper portion may be mounted to the surface cleaning head between a storage position and a floor cleaning position, and may include drive handle.

Claims

1. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, a lower end having a dirty air inlet and first and second laterally opposed sidewalls;

(ii) a brush motor drivingly connected to a moveable brushing member, the brush motor having a brush motor axis;

(iii) a cyclone assembly comprising a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber and positioned forward or rearward of the cyclone chamber, the cyclone having a longitudinal cyclone axis; and

,

(iv) a suction motor positioned at the rear end of the surface cleaning head, the suction motor having a first end, a second end and a suction motor axis extending between the first and second ends; and

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle;

wherein there is an absence of an operating component of the surface cleaning apparatus between the cyclone chamber and the dirt collection chamber.

2. The apparatus of claim 1 wherein the dirt collection chamber is positioned forward of the cyclone chamber.

3. The apparatus of claim 1 wherein the dirt collection chamber is positioned rearward of the cyclone chamber.

4. The apparatus of claim 1 wherein the dirt collection chamber is positioned between the cyclone chamber and the brush chamber.

5. The apparatus of claim 1 wherein the cyclone chamber has a dirt outlet positioned at a lateral outward end of the cyclone chamber.

6. The apparatus of claim 5 wherein the dirt outlet comprises an opening in a sidewall of the cyclone chamber.

7. The apparatus of claim 6 wherein the dirt outlet faces the dirt collection chamber.

8. The apparatus of claim 7 wherein the dirt outlet also faces upwardly.

9. The apparatus of claim 1 wherein the cyclone chamber and the dirt collection chamber have upper surfaces and the upper surface of the dirt collection chamber is at a height of or below the upper surface of the cyclone chamber.

10. The apparatus of claim 1 wherein the surface cleaning head has an upper surface having a profile and the cyclone assembly has an upper surface having a profile that conforms to the profile of the upper surface of the surface cleaning head.

11. The apparatus of claim 1 wherein the surface cleaning head has an upper surface having a profile and the dirt collection chamber has an upper surface having a profile that conforms to the profile of the upper surface of the surface cleaning head.

12. The apparatus of claim 1 wherein the dirt collection chamber has an openable end wall.

13. The apparatus of claim 12 wherein the dirt collection chamber and the cyclone chamber are concurrently openable.

14. The apparatus of claim 1 further comprising an air flow path extending rearwardly from a brush chamber outlet to the cyclone chamber and at least a portion of the first air flow path comprises a portion of the cyclone assembly.

15. The apparatus of claim 14 wherein the portion of the air flow path is positioned at a lateral inward end of the cyclone chamber.

16. The apparatus of claim 15 wherein a lateral outward end of the dirt collection chamber is openable.

17. The apparatus of claim 1 further comprising an air flow path extending rearwardly from a brush chamber outlet to the cyclone chamber and at least a portion of the first air flow path extends through the cyclone chamber.

18. The apparatus of claim 17 wherein the portion of the air flow path is positioned at a lateral outward end of the cyclone chamber.

19. The apparatus of claim 18 wherein a lateral outward end of the dirt collection chamber is openable.

20. The apparatus of claim 1 wherein the upper portion comprises a first end coupled to the surface cleaning head and a second end spaced apart from the first end and wherein the drive handle is disposed toward the second end.

21. The apparatus of claim 1 further comprising a mounting hub extending from the rear side of the surface cleaning head, the upper portion being moveably mounted to the mounting hub and being rotatably connected to the mounting hub whereby the upper portion is rotatable about a rotation axis relative to the surface cleaning head.

22. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, a lower end having a dirty air inlet and first and second laterally opposed sidewalls;

(ii) a brush motor drivingly connected to a moveable brushing member, the brush motor having a brush motor axis;

(iii) a cyclone assembly comprising a cyclone chamber having a closed lower end, a dirt outlet and a dirt collection chamber exterior to the cyclone chamber and positioned forward or rearward of the cyclone chamber, the cyclone having a longitudinal cyclone axis, wherein the dirt outlet faces upwardly; and

,

(iv) a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends; and

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle.

23. An all in the head surface cleaning apparatus comprising:

(a) a surface cleaning head comprising;

(i) a front end, a rear end, a lower end having a dirty air inlet and first and second laterally opposed sidewalls;

(ii) a brush motor drivingly connected to a moveable brushing member housed in a brush chamber, the brush motor having a brush motor axis;

(iii) a cyclone assembly comprising a cyclone chamber and a dirt collection chamber exterior to the cyclone chamber and positioned forward or rearward of the cyclone chamber, the cyclone having a longitudinal cyclone axis; and

,

(iv) a suction motor having a first end, a second end and a suction motor axis extending between the first and second ends; and

(b) an upper portion moveably mounted to the surface cleaning head between a storage position and a floor cleaning position, the upper portion comprising a drive handle;

wherein the dirt collection chamber extends from the cyclone chamber to the brush chamber along all of the length of the cyclone chamber in the direction of the cyclone axis.
