  • Self-cleaning steam iron
    Publication number: 20030136032
    Abstract: A self-cleaning steam iron has a self-cleaning function. The self-cleaning function is activated by an integrated steam control means which also controls the steam level in the ironing mode. The control means resets a steam iron to the ironing mode after each self-cleaning but does not alter the steam level set in the ironing mode unless a self-cleaning is performed subsequent to the steam level setting.
