Abstract
A steam iron is disclosed having a water tank, steam generating soleplate, a guided water valve to start and stop water to the soleplate for steam generation, and a dumper valve in the bottom of the tank to suddenly empty the tank onto the soleplate to purge and clean the iron. To this conventional structure an improvement provides a unitary assembly of the dumper valve that includes a first smoothly continuous tubular member with its upper end connected to the bottom of the tank and its lower end extended below the tank towards the soleplate. Cooperating with this is a second smoothly continuous concentric tubular member telescopically disposed frictionally with the first member so the two tubes are pushed and locked together. Each of the members has an inwardly directed flange at one end and at the opposite end from the other so that the flanges define reduced openings at the upper and lower tubular ends. A movable flat valve disc spans the upper opening below its flange and a spring is provided below the disc to bias it closed whereby the structure provides a complete and entire assembled subunit that may be fixedly locked in the tank bottom and is movable to direct all the water straight through the tubular members to suddenly empty the iron.
