Abstract

A handheld extraction cleaner includes a fluid delivery system and a recovery system including a suction nozzle, a recovery tank, and a suction source. The recovery tank has an auto-close feature that automatically seals an outlet of the tank when the recovery tank is mounted to a tank receiver of the extraction cleaner.

First claim

What is claimed is:

1. A handheld extraction cleaner, comprising:
a unitary body including a carry handle and a tank receiver;
a fluid delivery system including a supply tank on the unitary body and at least one fluid distributor; and
a recovery system including a working air path through the unitary body, a suction nozzle defining an inlet to the working air path, a suction source in fluid communication with the suction nozzle, and a recovery tank removably mounted to the tank receiver, the recovery tank comprising:
a collection chamber having an inlet opening and an outlet opening;
a tank body defining the collection chamber; and
a plug coupled with the tank body and moveable between a closed position in which the plug seals the outlet opening and an open position in which the plug is at least partially spaced from the outlet opening to form a drain path to empty dirty liquid in the recovery tank;
wherein the plug is configured to automatically move from the open position to the closed position by the mounting of the recovery tank to the tank receiver.

2. The handheld extraction cleaner of claim 1 , wherein:
the recovery system comprises a separator defining a portion of the working air path through the unitary body, the separator including an outlet aligned with the inlet opening of the recovery tank to transfer dirty liquid separated from a working airstream into the recovery tank; and
the recovery tank, the suction nozzle, and the separator form a modular unit that is removably coupled with the tank receiver.

3. The handheld extraction cleaner of claim 2 , wherein the modular unit comprises a brush between the suction nozzle and the recovery tank.

4. The handheld extraction cleaner of claim 1 , comprising a battery pack carried by the unitary body and electrically coupled with the suction source, wherein the battery pack is located at least one of:
rearwardly of a vacuum motor of the suction source; and
below the carry handle.

5. The handheld extraction cleaner of claim 1 , wherein the fluid delivery system comprises a pump carried by the unitary body, wherein the pump is located at least one of:
rearwardly of a vacuum motor of the suction source; and
below the carry handle.

6. The handheld extraction cleaner of claim 1 , wherein the plug is slidably mounted in the outlet opening, and wherein the plug does not separate from the outlet opening in the open position.

7. The handheld extraction cleaner of claim 1 , comprising a blocker on the unitary body that is positioned to push the plug to the closed position as the recovery tank is mounted to the tank receiver.

8. The handheld extraction cleaner of claim 7 , wherein the blocker depends within the tank receiver or adjacent to the tank receiver.

9. The handheld extraction cleaner of claim 7 , wherein the blocker comprises an engagement face that overlaps at least a portion of the plug when the recovery tank is mounted to the tank receiver.

10. The handheld extraction cleaner of claim 7 , wherein the plug comprises a stem and a cap on the stem.

11. The handheld extraction cleaner of claim 10 , wherein the stem is offset on the cap to define a drain passage below the stem in the open position.

12. The handheld extraction cleaner of claim 10 , wherein the cap comprises a head and outwardly extending flange on the head, wherein the head is sized to fit within the outlet opening with at least a portion of the flange extending over and outwardly of a rim of the outlet opening.

13. The handheld extraction cleaner of claim 12 , wherein the cap comprises a perimeter seal surrounding an outer perimeter of the head and the perimeter seal is sized to be compressed by an interior surface of the outlet opening.

14. The handheld extraction cleaner of claim 12 , comprising a blocker on the unitary body that is positioned to engage the cap and push the plug to the closed position as the recovery tank is mounted to the tank receiver.

15. The handheld extraction cleaner of claim 10 , wherein the stem comprises rails and the tank body comprises guides in the outlet opening that receive the rails to slidably mount the stem to the outlet opening.

16. The handheld extraction cleaner of claim 10 , wherein the stem comprises a stopper configured to one of inhibit or prevent the plug from being physically separated from the tank body.

17. The handheld extraction cleaner of claim 1 , comprising:
a first latch between the plug and the tank body to releasably retain the plug in the closed position; and
a second latch between the plug and the tank body to releasably retain the plug in the open position.

18. A handheld extraction cleaner, comprising:
a cleaner body including a forward end, a rearward end, and a tank receiver;
a fluid delivery system; and
a recovery system including a working air path through the cleaner body, a suction nozzle defining an inlet to the working air path, a suction source in fluid communication with the suction nozzle, and a recovery tank mounted to the tank receiver, the recovery tank comprising:
a collection chamber having an inlet opening and an outlet opening;
a tank body defining the collection chamber; and
a plug coupled with the tank body and configured to automatically seal the outlet opening when the recovery tank is mounted to the tank receiver.

19. The handheld extraction cleaner of claim 18 , wherein the plug is slidably mounted in the outlet opening.

20. The handheld extraction cleaner of claim 18 , comprising a blocker on the cleaner body that is positioned to push the plug to seal the outlet opening as the recovery tank is mounted to the tank receiver.
