ELECTRIC STEAM GENERATION

摘要

A steam generator e.g. for a hand-held portable appliance such as a domestic iron or steam cleaner comprises a water inlet (50; 172), a boiler (52; 174), a valve (46; 168) for controlling the entry of water into the boiler and means (42; 152) for delivering a surge of water to the boiler when the valve is opened. Also disclosed is an adaptor (12) for supplying electrical power to a mobile electrical appliance (1). The adaptor is operable in a corded mode when secured to the appliance for supplying electrical power and water while the appliance is being used; or a cordless mode when secured to a base unit (91) such that electrical and water connection can be made by placing the appliance (1) on or against the base unit; and broken by lifting or moving the appliance away from the base unit.
