Steam iron having valved demineralizing cartridge and secondary demineralized reservoir

摘要

A non-scaling electric steam iron has a heating sole plate (1), a steam chamber (3), a water reservoir (5), a feed device (6) for supplying water to the steam chamber, and a demineralizing cartridge (7) placed in the water circuit which connects the reservoir (5) to the steam chamber (3). The demineralizing cartridge (7) is placed in a removable manner between the primary plain-water reservoir (5) and a secondary demineralized-water reservoir (25) which communicates with the water feed device (6). The cartridge (7) communicates with the Primary reservoir (5) and the secondary reservoir (25) by the use of valves (27a,27b) which prevent any outflow of water when the cartridge is removed from the iron.
