Abstract

A vacuum cleaner has a separation/collection module with a housing and a cover pivotally mounted to the housing by a hinge. A filter assembly is carried by the cover and includes a filter media. When a user of the vacuum cleaner opens the cover, the filter media can be seen by the user.

First claim

What is claimed is:

1. A vacuum cleaner, comprising:
a suction nozzle;
a suction source fluidly connected to the suction nozzle; and
a separation/collection module comprising:
a housing defining a cyclone separator;
a cover pivotally mounted to the housing by a hinge and moveable between a close position and an open position; and
a filter assembly carried by the cover for movement therewith and comprising a filter media having an upstream surface and a downstream surface through which working air passes;
wherein when the cover is moved to the open position the upstream surface of the filter media is viewable from a user's vantage point.

2. The vacuum cleaner of claim 1 , wherein the downstream surface of the filter media is hidden from the user's vantage point when the cover is moved to the open position.

3. The vacuum cleaner from claim 1 , wherein the filter assembly is a pre-motor filter assembly and the suction source is fluidly downstream of the downstream surface of the filter media.

4. The vacuum cleaner of claim 1 , wherein the filter assembly comprises a filter housing coupled with the cover and defining a filter chamber.

5. The vacuum cleaner of claim 4 , wherein the filter housing seals against the housing in the closed position.

6. The vacuum cleaner of claim 4 , wherein the filter assembly further comprises a filter tray mounted within the filter chamber and retaining the filter media.

7. The vacuum cleaner of claim 1 , wherein the filter assembly further comprises a filter tray removably mounted within the cover and retaining the filter media.

8. The vacuum cleaner of claim 7 , wherein the filter tray comprises at least one filter inlet and at least one filter outlet which allow working air to pass through the filter media retained within the filter tray.

9. The vacuum cleaner of claim 7 , wherein the upstream surface and a downstream surface are opposing sides of the filter media.

10. The vacuum cleaner of claim 1 , wherein the filter media comprises one of a HEPA filter or a porous, non-pleated filter.

11. The vacuum cleaner of claim 1 , wherein the separation/collection module comprises an exhaust grill removably mounted to the cyclone separator and comprising a plurality of openings in fluid communication with the filter assembly.

12. The vacuum cleaner of claim 1 , wherein the cyclone separator comprises at least one cyclone chamber for separating contaminants from a dirt-containing working airstream and the separation/collection module comprises at least one collection chamber associated with the at least one cyclone chamber for receiving contaminants separated in the at least one cyclone chamber.

13. The vacuum cleaner of claim 1 , wherein the cover comprises an air outlet in fluid communication with the suction nozzle.

14. The vacuum cleaner of claim 1 , wherein the cover comprises a latch assembly selectively latching the cover in the closed position.

15. The vacuum cleaner of claim 14 , wherein the latch assembly comprises a latch engageable with the housing to latch the cover in the closed position and a latch actuator coupled with the latch, wherein the latch actuator conceals the latch from view from the user's vantage point when the cover is closed.

16. A vacuum cleaner, comprising:
a suction nozzle;
a suction source fluidly connected to the suction nozzle; and
a separation/collection module comprising:
a housing defining a cyclone separator;
a cover pivotally mounted to the housing by a hinge and moveable between a close position and an open position; and
a filter assembly carried by the cover for movement therewith and comprising a filter media having an upstream surface and a downstream surface through which working air passes;
wherein when the cover is moved to the open position the upstream surface of the filter media is exposed and the downstream surface is hidden.

17. The vacuum cleaner of claim 16 , wherein the filter assembly comprises a filter housing coupled with the cover and defining a filter chamber.

18. The vacuum cleaner of claim 17 , wherein the filter housing seals against the housing in the closed position.

19. The vacuum cleaner of claim 16 , wherein the filter assembly further comprises a filter tray removably mounted within the cover and retaining the filter media.

20. The vacuum cleaner of claim 19 , wherein the filter tray comprises at least one filter inlet and at least one filter outlet which allow working air to pass through the filter media retained within the filter tray.
