Abstract

A vacuum cleaner has a housing and a cover moveably mounted to the housing between a closed position and an open position. A filter is carried by the cover and includes an upstream surface and a downstream surface through which working air passes. When a user of the vacuum cleaner opens the cover, the upstream surface of the filter 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;
a housing defining a cyclone separator in fluid communication with the suction source;
a cover moveably mounted to the housing between a closed position and an open position; and
a filter carried by the cover for movement therewith and 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 is viewable from a user's vantage point.

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

4. The vacuum cleaner of claim 1 , and further comprising a filter housing coupled with the cover and defining a filter chamber, wherein the filter is in the 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 1 , and further comprising a filter tray removably mounted within the cover and retaining the filter.

7. The vacuum cleaner of claim 6 , 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 retained within the filter tray.

8. The vacuum cleaner of claim 6 , wherein the upstream surface and the downstream surface are on opposing sides of the filter.

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

10. The vacuum cleaner of claim 1 , wherein the housing comprises an exhaust grill removably mounted to the cyclone separator and comprising a plurality of openings in fluid communication with the filter.

11. 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 housing 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.

12. The vacuum cleaner of claim 1 , wherein the cover comprises an air outlet in fluid communication with the suction source in the closed position.

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

14. A vacuum cleaner, comprising:
a suction nozzle;
a suction source fluidly connected to the suction nozzle;
a housing in fluid communication with the suction source;
a cover moveably mounted to the housing between a closed position and an open position; and
a filter carried by the cover for movement therewith and 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 is exposed and the downstream surface is hidden.

15. The vacuum cleaner of claim 14 , and further comprising a filter housing coupled with the cover and defining a filter chamber, wherein the filter is in the filter chamber.

16. The vacuum cleaner of claim 14 , further comprising a filter tray removably mounted within the cover and retaining the filter.

17. The vacuum cleaner of claim 16 , 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 retained within the filter tray.

18. A vacuum cleaner, comprising:
a suction nozzle;
a suction source fluidly connected to the suction nozzle;
a housing defining a cyclone separator in fluid communication with the suction source and having a central axis;
a cover pivotally mounted to the housing by a hinge defining a pivot axis about which the cover moves between a closed position and an open position;
a filter carried by the cover for movement therewith and having an upstream surface and a downstream surface through which working air passes; and
a handle grip attached to the cover;
wherein the pivot axis of the cover is perpendicular to the handle grip; and
wherein the central axis of the cyclone separator passes through the filter and the handle grip when the cover is in the closed position.

19. The vacuum cleaner of claim 18 , wherein the downstream surface of the filter is hidden from a user's vantage point when the cover is moved to the open position.

20. The vacuum cleaner of claim 18 , and further comprising a filter housing coupled with the cover and defining a filter chamber, wherein the filter is in the filter chamber.
