Abstract
A steam ironing device includes a steam iron, a steam generator for generating steam and supplying steam to the steam iron, and a supply device for supplying water to the steam generator. During operation of the steam ironing device, scale is formed in the steam generator, and the water in the steam generator gradually gets contaminated with ions. In order to clean the steam generator and replace the water with fresh water, the steam generator is regularly subjected to an auto-rinsing process. A moment at which this process needs to take place is a moment at which an amount of scale and/or a concentration of ions have exceeded a predetermined maximum. The amount of scale and/or the concentration of ions are indirectly monitored by keeping account of a total quantity of water that has been supplied to the steam generator since a set starting point.
