<p>A steam iron with a water tank, handle structure, ported soleplate, water valve assembly, thermostat control passing through the tank, and a fill opening in the forward handle portion to pass water through a riser tube to fill the iron is standard structure. To this is applied an improvement in the riser tube which comprises a single substantially cylindrical integral plastic member having an outer flange around its middle to rest on the tank with the tube extending down into the tank. The tube has a forward cut-away portion with the rear portion forming a baffle both being in the tank. The tube top is closed by a wall and a forward extension below the top wall is connected to the fill opening with an apertured baffle in the tube behind the extension. The top of the tube has a series of openings for selective use such as for self-clean or spray features and an operable stem extends through one of the openings connecting to the water valve. The riser tube has suitable vents and skirt extension to properly orient and lock the tube in position. Thus, a single integral plastic riser tube fills the water tank, it forms baffling in both the tank and fill opening for water retention, it has suitable vents to aid in filling and emptying and, it forms a guide for other selected features such as self-clean and spray that may be used in a basic iron.</p> |
