Abstract
A recycling extraction cleaner and dryer is provided which includes a unitary body member having a vacuum blower chamber, a plenum chamber and a nozzle head including a drying air discharge, a cleaning fluid discharge and a vacuum intake. A cleaning fluid container is removably mounted on the body to communicate with the cleaning fluid discharge, and a vacuum generator in the vacuum blower chamber creates a vacuum in the plenum chamber which communicates with the vacuum intake. The vacuum generator creates an exhaust air flow in the vacuum blower chamber which is directed to the drying air discharge to provide drying air under pressure to a surface to be cleaned and to increase the pressure differential between the plenum chamber and the surface contacting side of the nozzle head.
Claims26
An extraction cleaner for cleaning a surface comprising:
- a body member for housing internal cleaner components including a handle at a first end thereof, a nozzle head at a second end thereof opposite to and spaced from said first end, said nozzle head including a cleaning fluid discharge means and a vacuum intake means, a vacuum blower chamber formed adjacent to said handle, and a plenum chamber formed adjacent to said vacuum blower chamber, said body member including a fluid chamber seating area between said nozzle head and said plenum chamber;
- a fluid receiving chamber removably mounted in said fluid chamber seating area for containing cleaning fluid, said fluid receiving chamber being mounted in communication with said plenum chamber, means connecting said fluid receiving chamber to said cleaning fluid discharge means to provide cleaning fluid from said fluid receiving chamber to said cleaning fluid discharge means;
- a vacuum generating means mounted in said vacuum blower chamber and operative to create a vacuum in said plenum chamber and fluid receiving chamber;
- a vacuum conduit means connecting said vacuum intake means to said fluid receiving chamber, said vacuum conduit means including a conduit inner end section and an elongated conduit extending from said nozzle head to said conduit inner end section, said conduit inner end section curving inwardly of said plenum chamber and downwardly at an angle into said fluid receiving chamber to direct fluid and air in said vacuum conduit means downwardly into said fluid receiving chamber;
- and
- a return air conduit means spaced above the conduit inner end section and connecting said plenum chamber to said vacuum blower chamber and having a first end opening into said vacuum blower chamber and a second end opening into said plenum chamber, said return air conduct means including a first conduit section extending from said first end downwardly into said plenum chamber toward said fluid receiving chamber and a second conduit section extending laterally frown said first conduit section to said second end to form an enclosed passageway from said first end to said second end.
