<p>The invention is directed to a self-cleaning steam iron with means to purge the iron through the soleplate by providing a substantially separate large opening in the iron's water tank with a dump valve so the water can be suddenly dumped onto the hot soleplate. With the additional steam suddenly generated, the entire tank, steam distribution system, and ports are completely and forcefully purged of water, steam, loose residues, and entrapped lint. An additional function to this self-cleaning combination uses the same structure with a separate steam knob to actuate the dumping structure separately and in pulses to provide a surge of steam through the soleplate upon actuation. The same knob, on continuous actuation, converts the iron into a dry iron. Thus, common structure provides a multi-function steam iron.</p> |
