Abstract

A motor enclosure for a vacuum cleaner includes a body having both a motor receiver for receiving a motor and a filter receiver for receiving a filter.

Claims

1. A motor enclosure for a vacuum cleaner including both a motor and a filter, said motor enclosure comprising:

a body including both a motor receiver and a filter receiver.

2. The motor enclosure of claim 1 wherein said body further includes at least one conduit having a first end in fluid communication with said motor receiver and a second end in fluid communication with said filter receiver.

3. The motor enclosure of claim 1, wherein said body further includes a first conduit and a second conduit, said first and second conduits each having a first end in fluid communication with said motor receiver and a second end in fluid communication with said filter receiver.

4. The motor enclosure of claim 3, wherein said body includes a first section and a second section that are secured together.

5. The motor enclosure of claim 4, wherein said first section includes said motor receiver and said second section includes said filter receiver.

6. The motor enclosure of claim 5, wherein a first fastening feature is provided on said first section and a second, cooperating fastening feature is provided on said second section.

7. The motor enclosure of claim 6 wherein said first section includes said first and second conduits.

8. The motor enclosure of claim 7 wherein said first fastening feature is provided on said first and second conduits.

9. The motor enclosure of claim 8, wherein said first and second fastening features are cooperating tabs and apertures.

10. The motor enclosure of claim 9, wherein said second section includes first and second filter receiver inlets, said first and second filter receiver inlets communicating with said first and second conduits.

11. The motor enclosure of claim 10, wherein said filter receiver includes a filter support.

12. The motor enclosure of claim 11, further including a filter in said filter receiver and an inlet manifold between said filter and said first and second filter receiver inlets.

13. The motor enclosure of claim 11, further including a filter adapter having a frame engaging said filter support and a filter cavity for holding a filter.

14. The motor enclosure of claim 12, wherein said second section includes a removable cover allowing access to said filter receiver.

15. The motor enclosure of claim 14, further including an outlet manifold between said filter and said cover.

16. The motor enclosure of claim 15, further including an exhaust outlet in said second section in fluid communication with said outlet manifold.

17. The motor enclosure of claim 10, wherein said first section includes a closed end adjacent said second section and an open end opposite said closed end.

18. The motor enclosure of claim 17, further including a first motor support engaging said open end of said first section.

19. The motor enclosure of claim 18, wherein said first motor support is annular and constructed from vibration damping material.

20. The motor enclosure of claim 19, further including a second motor support engaging said closed end of said first section.

21. The motor enclosure of claim 20, wherein said second motor support is constructed from vibration damping material.

22. The motor enclosure of claim 21, wherein said closed end includes a mounting aperture and said second motor support includes a projection received in said mounting aperture.

23. The motor enclosure of claim 22, wherein said second motor support includes at least one protuberance.

24. The motor enclosure of claim 23, further including a fan and motor assembly in said motor receiver.

25. The motor enclosure of claim 24, wherein said fan and motor assembly includes a housing.

26. The motor enclosure of claim 25, wherein said first motor support engages a first end of said housing and a second motor support engages a second end of said housing.

27. The motor enclosure of claim 26, wherein said housing includes at least one mounting hole and said at least one protuberance is received in said mounting hole.

28. The motor enclosure of claim 27, wherein said projection includes a hub opening and said fan and motor assembly includes a hub received in said opening.

29. The motor enclosure of claim 28, wherein said closed end includes a first pair of spaced slots and said second motor support includes a second pair of spaced slots, said first and second pair of slots defining a pair of electrical conductor inlets.

30. The motor enclosure of claim 29, wherein said pair of electrical conductor inlets are provided at opposite sides of said fan and motor assembly.
