Abstract
An accessory tool for an extraction cleaner having an accessory hose, a fluid delivery system, and a fluid recovery system includes a lens, a tool body, a spray tip, and a cleanout assembly. The tool body is connectable to the fluid delivery system and the fluid recovery system via the accessory hose. The lens couples to the tool body to form a suction nozzle volume therebetween. The tool body defines a fluid channel opposite the lens. The spray tip dispenses a cleaning fluid from the fluid delivery system onto a surface during a spray cycle of the extraction cleaner. The cleanout assembly selectively diverts the cleaning fluid from the spray tip and into the suction nozzle volume via the fluid channel during a clean out cycle of the extraction cleaner to thereby clean the lens and the accessory hose.
Claims19
An accessory tool for an extraction cleaner having an accessory hose with a wand, a fluid delivery system, and a fluid recovery system, the accessory tool comprising:
- a lens;
- a tool body connectable to said fluid delivery system and said fluid recovery system via said accessory hose, wherein the lens is coupled with the tool body to form a suction nozzle opening into a suction nozzle volume between the lens and a rear tool wall, and wherein the rear tool wall at least partially defines a transverse fluid channel opposite the lens, adjacent to the suction nozzle opening, and in fluid communication with the suction nozzle volume, wherein the transverse fluid channel includes a radiused channel portion and a wall contiguous with the radiused channel portion;
- a spray tip configured to dispense a cleaning fluid from said fluid delivery system onto a surface during a spray mode of said extraction cleaner;
- and
- a cleanout assembly coupled to the tool body and configured to selectively divert the cleaning fluid from the spray tip and into the transverse fluid channel during a clean out mode of said extraction cleaner to thereby clean the lens and the accessory hose.
An accessory tool for an extraction cleaner having an accessory hose with a wand including a spray actuator, a fluid delivery system, and a fluid recovery system, the accessory tool comprising:
- a lens;
- a tool body connectable to said fluid delivery system and said fluid recovery system via said accessory hose, wherein the lens couples to the tool body forming a suction nozzle volume therebetween;
- a spray tip configured to dispense a cleaning fluid from said fluid delivery system in response to actuation of said spray actuator;
- a cleanout assembly configured to selectively divert the cleaning fluid from the spray tip and into the suction nozzle volume to thereby clean the lens and the accessory hose, wherein the cleanout assembly includes:
- a diverter sleeve slidable between a spray position and a clean out position, wherein the cleaning fluid is dispensed from the spray tip to a surface when the diverter sleeve is in the spray position, and wherein the diverter sleeve is configured to translate over the spray tip to move the diverter sleeve to the clean out position, the cleaning fluid being diverted from the spray tip into the suction nozzle volume when the diverter sleeve is in the clean out position;
- and
- a rinse tip, wherein the rinse tip is configured to conduct the cleaning fluid into the suction nozzle volume when the diverter sleeve is in the clean out position;
- and
- a tool actuator operably coupled to the tool body, wherein the tool actuator is operably coupled to the diverter sleeve and configured to move the diverter sleeve between the spray position and the clean out position.
An extraction cleaner, comprising:
- an accessory hose;
- a fluid delivery system;
- a fluid recovery system;
- and
- an accessory tool comprising:
- a lens;
- a tool body connectable to the fluid delivery system and the fluid recovery system via the accessory hose, wherein the lens couples to the tool body to form a suction nozzle volume therebetween, the tool body comprises a rear tool wall that defines a transverse fluid channel recessed into the rear tool wall to define a channel portion contiguous with a wall that extends to the rear tool wall, and wherein the transverse fluid channel is arranged parallel to and adjacent to a nozzle opening of the suction nozzle volume;
- a spray tip configured to dispense a cleaning fluid from the fluid delivery system onto a surface during a spray mode of said extraction cleaner;
- and
- a cleanout assembly configured to selectively divert the cleaning fluid from the spray tip, through a fluid junction in a rinse tip, along the transverse fluid channel, and into the suction nozzle volume during a clean out mode of said extraction cleaner to thereby clean the lens and the accessory hose.
