  • Patent number: 7913433
    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.

  • Patent number: 6763620
    Abstract: The invention relates to a steam iron with instantaneous vaporization comprising a water container (2), a steam chamber (32), an anti-drip device (80) and a drip device having a rod (4) which moves axially. According to the invention, the total stroke of the axially-moving rod (4) comprises a first stroke which provides the flow of water through the opening (520) of a module (5) that receives the water from the container (2) via the anti-drip device (80) and a second stroke which simultaneously opens a direct passage for the water to flow from the container (2) to the module (5) and moves the module (5) by opening a larger hole for the water to flow from the container to the steam chamber.

  • Patent number: 6622938
    Abstract: A displaceable nozzle (8) of an injection steam generator for small appliances, particularly irons or ironing stations, comprising a steam chamber (3) inside a steam generator housing (1) provided with an injection opening (5), is positioned telescopically on a fixed member to define a nozzle chamber (10). This nozzle (8) can be displaced by an inside pressure in the nozzle chamber in a first pressure range in the direction of the injection opening (5) and can be moved back from the injection opening (5) by a restoring force e.g., a restoring spring (12), wherein the inside pressure in the nozzle chamber (10) is lower in second pressure range than in the first pressure range. A drain passage (18) for the nozzle chamber 10 is connected via a valve arrangement (19, 21) to the fixed member (11), so that excess residual water, which exits when the nozzle (18) is moved back from the nozzle chamber (10), does not cause calcification of the nozzle opening (9) and the injection opening (5).

  • Patent number: 6615515
    Abstract: A steam iron includes an iron unit and an evaporating unit. The evaporating unit includes a horizontal partition that divides a steam generating chamber into upper and lower chamber portions. Water is evaporated within the lower chamber portion so as to form steam that raises the partition, thereby permitting steam flow from the lower chamber portion into the upper chamber portion.

  • 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.

  • Patent number: 6209239
    Abstract: To prevent water particles or mist carried by steam exiting from the steam vents of a steam iron, the steam generated in its steam chamber follows tortuous paths from both a vaporization section and a blast path to the steam vents. A baffle having a concave front face spans across the rear of the vaporization section and the open rear ends of the blast path face the concave baffle face. The lid of the steam chamber is sealed by pressure to the baffle and to a pair of ribs that define the sides of the blast path. The outer rib is higher than the inner rib so that, if the seal between the lid fails, the failure will likely occur between the inner rib and the lid so that any water escaping from the blast path will likely enter the vaporization chamber and not exit through a steam vent.
