ABSTRACT:
In a steam iron with the water tank above an electrically heated soleplate with steam apertures, a primary steam generator is disposed in the soleplate and fed from the tank by a metering water valve for steam generation. A cover plate over the soleplate forms distributing passages connecting the primary generator with the apertures and a separate surge generator is provided and fed by a surge valve for intermittent steam generation. A duct connects the surge generator in upstream flow series relation so surge steam flows through the duct into the primary generator and then through the distributing passages to the apertures for a surge of steam. To this general arrangement, an improvement is provided comprising a converging nozzle means forming the exit from the duct and discharging centrally of the primary generator whereby the nozzle increases the surge steam velocity into the primary generator to scrub the generator before entering the distribution passages to the soleplate apertures.
