ABSTRACT:
An adjustable steam flow control for an electric steam iron includes a metering rod mounted in threaded engagement with a support bushing and having a lower end that extends into a valve orifice between the water reservoir and the steam generation chamber. A pinion gear is secured to the metering rod and engages a spur gear sector on a rotatably mounted steam adjust knob. Rotation of the steam adjust knob in one direction or the other by the user causes the metering rod to rotate in its bushing and advance into or retract from the orifice to thus control the steam flow rate. The steam control knob is provided with a spur gear sector so that partial rotation of the steam control knob will rotate the metering rod through its full range of motion. The present invention advantageously provides an adjustable steam flow control for an electric steam iron in which steam control can be precisely controlled and in which repeatable increments or decrements of steam flow can be obtained in a positive manner.
