Abstract

A surface cleaning apparatus comprises a dirt inlet, a handle, a cyclone separator having an outer wall, a top, a fluid inlet downstream from the dirt air inlet and a fluid outlet, a screen positioned around the fluid outlet such that fluid exiting the cyclone separator passes through the screen and the screen is removable through the top of the cyclone separator, and, a fluid flow motor.

Claims

1. A surface cleaning apparatus comprising:

(a) a dirt inlet;

(b) a handle;

(c) a cyclone separator having an outer wall, a top, a fluid inlet downstream from the dirt air inlet and a fluid outlet;

(d) a screen positioned around the fluid outlet such that fluid exiting the cyclone separator passes through the screen and the screen is removable through the top of the cyclone separator; and

,

(e) a fluid flow motor.

2. The surface cleaning apparatus of claim 1 wherein the fluid outlet has an upper portion positioned above the top of the cyclone separator and is removable with the screen.

3. The surface cleaning apparatus of claim 1 wherein the upper portion of the fluid outlet is a handle for the screen.

4. The surface cleaning apparatus of claim 1 wherein a fluid flow conduit is collinear with the fluid outlet, extends through the cyclone chamber and has an upper portion positioned above the top of the cyclone separator and the upper portion of the fluid outlet is a handle for the screen.

5. The surface cleaning apparatus of claim 1 wherein the screen is rotatably mounted to the cyclone separator.

6. The surface cleaning apparatus of claim 1 wherein the screen has a larger diameter than the fluid outlet.

7. The surface cleaning apparatus of claim 5 wherein the top of the cyclone chamber has a removable annular band that has a diameter larger than the diameter of the screen.

8. The surface cleaning apparatus of claim 6 wherein the removable annular band is removable with the fluid conduit.

9. The surface cleaning apparatus of claim 6 wherein the removable annular band forms a one piece assembly with the fluid conduit.

10. The surface cleaning apparatus of claim 1 wherein the screen has an outer perimeter defining a cavity and a transverse member extending across the cavity.

11. The surface cleaning apparatus of claim 1 wherein the fluid outlet has an inlet and the screen has a longitudinal surface that is parallel to the fluid outlet and has first and second opposed ends one of which is positioned below the inlet of the fluid outlet, and the transverse member extends across a central region defined by the longitudinal surface and the inlet to the fluid outlet is surrounded by the longitudinal surface and the transverse member.

12. The surface cleaning apparatus of claim 11 wherein the transverse member is positioned mid way along the longitudinal surface.

13. The surface cleaning apparatus of claim 10 wherein the first opposed end is positioned towards the top and the transverse member is positioned adjacent the first opposed end.

14. The surface cleaning apparatus of claim 10 wherein the second opposed end is positioned distal from the top and the transverse member is positioned adjacent the second opposed end.

16. The surface cleaning apparatus of claim 14 wherein the transverse member is positioned between the first and second opposed ends and the inlet to the fluid outlet is surrounded by the longitudinal surface and the transverse member.

18. The surface cleaning apparatus of claim 14 wherein the first opposed end is positioned towards the top and the transverse member is positioned adjacent the first opposed end.

19. The surface cleaning apparatus of claim 14 wherein the screen is removable.

20. The surface cleaning apparatus of claim 14 wherein the screen is removable through the top of the cyclone separator.

21. The surface cleaning apparatus of claim 18 wherein the fluid outlet has an upper portion positioned above the top of the cyclone separator and is removable with the screen.

22. The surface cleaning apparatus of claim 19 wherein the upper portion of the fluid outlet is a handle for the screen.

23. The surface cleaning apparatus of claim 18 wherein the screen is rotatably mounted to the cyclone separator.

24. The surface cleaning apparatus of claim 18 wherein the screen has a larger diameter than the fluid outlet.

25. The surface cleaning apparatus of claim 23 wherein the top of the cyclone chamber has a removable annular band that has a diameter larger than the diameter of the screen.

26. The surface cleaning apparatus of claim 24 wherein the removable annular band is removable with the fluid conduit.

27. The surface cleaning apparatus of claim 24 wherein the removable annular band forms a one piece assembly with the fluid conduit.

15. A surface cleaning apparatus comprising:

(a) a dirt inlet;

(b) a handle;

(c) a cyclone separator having an outer wall, a top, a fluid inlet downstream from the dirt air inlet and a fluid outlet, the fluid outlet having an inlet;

(d) a screen positioned around the inlet of the fluid outlet, the screen having a longitudinal surface that is parallel to the fluid outlet and has first and second opposed ends one of which is positioned below the inlet of the fluid outlet, and a transverse member positioned to define a cavity interior of the longitudinal surface that is open to the fluid in the cyclone separator without passing through the screen; and

,

(e) a fluid flow motor.

17. The surface cleaning apparatus of claim 15 wherein the transverse member is positioned mid way along the longitudinal surface.
