ABSTRACT:
A combination flash/flood boiler steam iron with a water tank having a fill opening and a liquid fill valve means to close the tank to ambient and having a steam generating soleplate with ports and boiler therein and a water valve to start and stop a metered flow of water to the boiler for generating flash steam. In this combination the improvement is added for selectively operating the iron with a flooded boiler comprising a separate flood valve means operable to partially empty the tank and fill the boiler to a flooded condition to generate saturated steam. A tubular means connects the boiler and water tank to balance both pressure within the iron and water level during flooded operation and to conduct all the generated steam to the tank interior. A steam passage distributing means connects to the soleplate ports and the distributing means is separated from the boiler generating means. Pressure control conduit means connects the tank interior and the distributing means whereby the iron operates dry with the valves closed to prevent steam generation; it operates with flash steam with the water valve open; and it operates flooded with saturated steam with the flood valve open; thus providing flexibility in several modes of operation. Additionally, a removable spout may be attached to the fill opening forming a steam nozzle so the iron may be used as a fabric steamer on vertically hanging garments.
