Abstract

An extraction cleaner is provided with a removable recovery tank having a drain opening quick-empty valve and actuator assembly for emptying the tank. The actuator assembly may include a quick-release latch for a bottom-empty door or a drain plug for sealing the drain opening. The quick-release latch may include a button remote from the door or drain plug.

First claim

What is claimed is:

1. An extraction cleaner, comprising
a housing that comprises an upright assembly having a handle where the upright assembly is pivotally connected to a base assembly for directing the base assembly across a surface to be cleaned;
a suction nozzle provided on the housing;
a suction source provided on the housing and in fluid communication with the suction nozzle for generating a working airstream; and
a recovery tank for separating and collecting fluid and debris from the working airstream for later disposal, wherein the recovery tank is removably mounted on the housing and comprises:
a recovery container defining a recovery chamber and comprising a drain opening provided on a lower portion of the recovery container;
a valve fluidly connected to the drain opening for movement between a closed position for sealing the recovery chamber and an open position for draining fluid from the recovery chamber; and
an actuator for selectively opening the valve, wherein at least a portion of the actuator is provided on an upper portion of the recovery container.

2. The extraction cleaner of claim 1 , wherein the valve comprises a bottom empty door that is hingedly connected to the container for movement between a closed position in which the door covers the drain opening and an open position in which the door is separated from the drain opening.

3. The extraction cleaner of claim 2 , wherein the recovery container comprises a bottom wall, and wherein the drain opening is formed through the bottom wall and the bottom empty door is hingedly connected to the bottom wall wherein the bottom empty door comprises a drain plug, and wherein the drain plug is configured to seal the drain opening when the bottom empty door is in the closed position.

4. The extraction cleaner of claim 1 , wherein the actuator comprises:
a push rod configured to selectively open the valve; and
a user-engagable push button operably connected to the push rod and provided on the upper portion of the recovery container.

5. The extraction cleaner of claim 4 , and further comprising a door latch holding the door closed, wherein the push rod is configured to selectively release the door latch.

6. The extraction cleaner of claim 4 , wherein the recovery container comprises a bottom wall in which the drain opening is formed and a peripheral side wall extending upwardly from the bottom wall, and wherein the push rod is provided on an outside surface of the peripheral side wall for sliding movement along the outside surface of the peripheral side wall.

7. The extraction cleaner of claim 4 , wherein the push rod is routed inside the recovery container for sliding movement within the recovery chamber.

8. The extraction cleaner of claim 4 , and further comprising a carry handle coupled with the recovery container, wherein the user-engagable push button is provided on the carry handle.

9. The extraction cleaner of claim 1 , wherein the valve comprises a drain plug, and the actuator comprises a push rod connected to the drain plug.

10. The extraction cleaner of claim 1 , wherein the recovery container comprises a bottom wall in which the drain opening is formed, a peripheral side wall extending upwardly from the bottom wall, and a top wall, wherein the actuator comprises a user-engagable button provided on the top wall.

11. The extraction cleaner of claim 1 , wherein the recovery tank further comprises an air/liquid separator within the recovery container.

12. The extraction cleaner of claim 11 , wherein the air/liquid separator is removably mounted in the recovery container, and the recovery container has an insertion opening provided on the lower portion of the container through which the air/liquid separator is inserted into and removed from the recovery chamber, wherein the insertion opening is separate from the drain opening.

13. The extraction cleaner of claim 1 , wherein the housing comprises a base assembly and an upright assembly pivotally connected to the base assembly, wherein the suction nozzle is provided on the base assembly.

14. The extraction cleaner of claim 13 , wherein the recovery tank is removably mounted on the upright assembly.

15. The extraction cleaner of claim 1 , and further comprising a fluid delivery system for storing cleaning fluid and delivering cleaning fluid to the surface to be cleaned.

16. The extraction cleaner of claim 1 , and further comprising at least one supply container for storing a supply of fluid and at least one fluid distributor in fluid communication with the at least one supply container.

17. An extraction cleaner, comprising
a housing;
a suction nozzle provided on the housing;
a suction source provided on the housing and in fluid communication with the suction nozzle for generating a working airstream; and
a recovery tank for separating and collecting fluid and debris from the working airstream for later disposal, wherein the recovery tank is removably mounted on the housing and comprises:
a recovery container defining a recovery chamber and comprising a drain opening provided on a lower portion of the recovery container;
a valve fluidly connected to the drain opening for movement between a closed position for sealing the recovery chamber and an open position for draining fluid from the recovery chamber wherein the valve comprises a bottom empty door that is hingedly connected to the container for movement between a closed position in which the door covers the drain opening and an open position in which the door is separated from the drain opening; and
an actuator for selectively opening the valve, wherein at least a portion of the actuator is provided on an upper portion of the recovery container.
