ABSTRACT:
An electric steam iron includes a plastic housing shell forming a hollow handle structure and a soleplate with steam generating means and ports for distribution of steam. A pump actuated by a handle button delivers water from a tank within the housing shell to the steam generating means. The iron is controlled by a low DC voltage electronic control including a printed circuit board disposed in the housing shell away from the soleplate and having means including a power resistor for reducing high AC line voltage to low DC supply to the circuit. The shell and hollow handle structure are open to the soleplate and the printed circuit board is directly exposed to heat from the power resistor. The power resistor is mounted directly on the soleplate between a pair of upstanding ribs on the soleplate and is cemented in thermally close coupling thereto by a heat transfer compound so that substantially all of the heat from the power resistor is conducted directly into the soleplate during use of the iron, thus preventing excessive heating of the printed circuit board and allowing the printed circuit board to be located within the housing shell.
