Abstract
Self-cleaning features for extraction cleaners and attachments for extraction cleaners, such as accessory tools, wands, and/or hoses, are provided. The self-cleaning features are configured redirect cleaning fluid from a fluid supply system of the extraction cleaner into a working air or fluid recovery path of the extraction cleaner, including, but not limited to into the working air or fluid recovery path of a tool, wand, and/or hose of the extraction cleaner.
Claims20
An external accessory for an extraction cleaner, the accessory comprising:
- a hand-held housing adapted for operational attachment to the extraction cleaner;
- a fluid delivery pathway extending through the housing between a fluid inlet and a fluid distributer, wherein the fluid inlet is configured for fluid communication with a supply container disposed in the extraction cleaner and adapted to contain a cleaning fluid and the fluid distributor is configured to deliver the cleaning fluid to a surface to be cleaned;
- an airflow pathway extending through the housing between a suction nozzle at a forward portion of the housing and an air outlet at a rearward portion of the housing, wherein the air outlet is in fluid communication with a recovery container disposed in the extraction cleaner and is configured to deliver a mixture of waste fluid and waste to the recovery container;
- and
- a diverter assembly disposed within or on the housing and configured to selectively divert the cleaning fluid into the airflow pathway downstream of the suction nozzle and upstream of the air outlet;
- wherein the diverter assembly in a first position corresponds to a surface cleaning mode for the accessory and the diverter assembly in a second position corresponds to a self-cleaning mode of the accessory.
An external accessory for an extraction cleaner, the accessory comprising:
- a hand-held housing adapted for operational attachment to the extraction cleaner;
- an airflow pathway extending through the housing between a suction nozzle at a forward portion of the housing and an air outlet at a rearward portion of the housing, wherein the air outlet is in fluid communication with a recovery container disposed in the extraction cleaner and is configured to deliver a mixture of waste fluid and waste mixture to the recovery container;
- a fluid delivery pathway extending through the housing between a fluid inlet and a fluid distributer, wherein the fluid inlet is configured for fluid communication with a supply container disposed in the extraction cleaner containing a cleaning fluid and the fluid distributor is configured to deliver the cleaning fluid to a surface to be cleaned;
- and
- a diverter assembly configured to selectively divert the cleaning fluid into the airflow pathway downstream of the suction nozzle and upstream of the air outlet;
- wherein the diverter assembly is disposed within or on the housing and at least a portion of the diverter assembly is moveable between a first position corresponding to a surface cleaning mode of the accessory and a second position corresponding to a self-cleaning mode of the accessory.
An external accessory for an extraction cleaner having a fluid delivery system comprising a supply container containing a cleaning fluid and a waste fluid and waste recovery system comprising a suction source and a recovery container for recovery of a waste fluid and waste mixture, the accessory comprising:
- a multi-part hand-held tubular housing adapted for operational attachment to the extraction cleaner;
- an airflow pathway extending through the housing between a suction nozzle at a forward portion of the housing and an air outlet at a rearward portion of the housing, wherein the air outlet is in fluid communication with the recovery container and is configured to deliver the waste fluid and waste mixture to the recovery container;
- a fluid delivery pathway extending through the housing between a fluid inlet and a fluid distributer, wherein the fluid inlet is configured for fluid communication with the supply container and the fluid distributor is configured to deliver the cleaning fluid to a surface to be cleaned;
- and
- a diverter assembly disposed within or on the housing, wherein at least a portion of the diverter assembly is moveable between a first position corresponding to a surface cleaning mode for the accessory and a second position corresponding to a self-cleaning mode of the accessory;
- wherein the diverter assembly defines a conduit between the fluid delivery pathway and airflow pathway when the diverter assembly is displaced to the second position to selectively divert the cleaning fluid into the airflow pathway downstream of the suction nozzle and upstream of the air outlet.
