Abstract

A wet and dry vacuum cleaner system is disclosed, wherein the system includes a debris container having an inlet and outlet, a filter support having a filter and being adapted to situate at least a portion of the filter within the container and intermediate between the inlet and outlet, a vacuum unit adapted to be coupled to the container, and a housing. A wet/dry vacuum appliance system is also disclosed, which includes means for housing a vacuum unit, means for slidably receiving a debris container, and means for releasably holding the container in sealed engagement with the vacuum unit. In addition, methods of removing debris from such a vacuum cleaner and vacuum appliance systems are described.

Claims

1. A wet and dry vacuum cleaner system, comprising:

a housing;

a vacuum unit contained within the housing;

a container for receiving debris, the container slidably received within the housing below the vacuum unit, the container having an air inlet and air outlet;

a filter support removably coupled to the container, the filter support having a filter and the filter support being adapted to situate at least a portion of the filter within the container;

wherein the housing includes tracks within which supports of the container glide as the container is slid within the housing, the tracks include ramps configured to raise a rear portion of the container as the container is slid within the housing;

at least one latch configured to lift a front portion of the container and thereby sealingly couple the container to the vacuum unit.

2. The vacuum cleaner system of claim 1, wherein the container has at least one gasket adapted to sealingly engage the vacuum unit.

3. The vacuum cleaner system of claim 1, wherein the vacuum unit has at least one gasket adapted to sealingly engage the container.

4. The vacuum cleaner system of claim 1, wherein the container is freely mobile upon being decoupled from the housing by releasing the at least one latch.

5. The vacuum cleaner system of claim 1, wherein the container slides within the housing on rollers.

6. The vacuum cleaner system of claim 1, wherein the container slides within the housing on glides.

7. The vacuum cleaner system of claim 1, the filter support further including a float therein and a float retainer configured to retain the float within the filter support.

8. The vacuum cleaner system of claim 1, further including tabs that engage recesses when the container is coupled to the vacuum unit, thereby resisting lateral forces on the container, wherein the tabs extend up from the container into the recesses located within the vacuum unit, when the container is coupled to the vacuum unit.

9. The vacuum cleaner system of claim 1, further including tabs that engage recesses when the container is coupled to the vacuum unit, thereby resisting lateral forces on the container, wherein the tabs extend down from the vacuum unit into the recesses located within the container, when the container is coupled to the vacuum unit.

10. A wet and dry vacuum cleaner system, comprising:

a housing having two side panels;

a vacuum unit coupled between the two side panels of the housing, the vacuum unit having a bottom;

a container removably sealed to the bottom of the vacuum unit, the container having an air inlet and air outlet, the container being slidably received within slots of the two side panels of the housing;

wherein the housing includes the slots within which supports of the container glide as the container is slide within housing, the slots include ramps at a rear of the slots, the ramps being configured to raise a rear portion of the container as the container is slid within the housing; and

a filter support having a filter, the filter support being removably coupled between an inside of the container and the vacuum unit such that air traveling from the container to the vacuum unit passes through the filter and the filter support being adapted to situate at least a portion of the filter within the container.

11. The vacuum cleaner system of claim 10, wherein the container is slidingly removable from the housing when the container is uncoupled from the vacuum unit.

12. The vacuum cleaner of claim 10, wherein the container further comprises rollers that communicate with the slots.

13. The vacuum cleaner system of claim 10, wherein the slots support and lift a rear portion of the container as the container is slid into the housing and coupled to the vacuum unit.

14. The vacuum cleaner system of claim 10, further including at least one latch at least partially mounted on a front portion of the container which lifts the front portion of the container as the container is slid into the housing and coupled to the vacuum unit.

15. The vacuum cleaner system of claim 10, wherein the side panels of the housing include slots which support a front portion of the container as the container is slid into the housing and coupled to the vacuum unit.

16. The vacuum cleaner system of claim 10, wherein the container has at least one gasket adapted to sealingly engage the vacuum unit.

17. The vacuum cleaner system of claim 10, wherein the vacuum unit has at least one gasket adapted to sealingly engage the container.

18. The vacuum cleaner system of claim 10, further including tabs that extend up from the container to engage recesses in the vacuum unit when the container is coupled to the vacuum unit, thereby resisting lateral forces on the container.

19. The vacuum cleaner system of claim 10, further including tabs that extend down from the vacuum unit to engage recesses in the container when the container is coupled to the vacuum unit, thereby resisting lateral forces on the container.
