  • Steam discharge unit for use in a soleplate of a steam iron
    Patent number: 8615909
    Abstract: A steam discharge unit (1) comprises a chamber (10) for accommodating a flow of a water-steam mixture and heating the water-steam mixture, an inlet (11) to the chamber (10), and an outlet (12) from the chamber (10). In order to avoid water droplets from exiting the chamber (10) through the outlet (12) along with a flow of steam, special measures are taken, which comprise a barrier (20) arranged inside the chamber (10), in a flow path of a water-steam mixture from the inlet (11) to the outlet (12), and a hydrophobic surface (30) arranged preferably close to the outlet (12). In case water droplets remain inside the chamber (10) and tend to move towards the outlet (12), an actual release of the water droplets from the chamber (10) cannot take place by virtue of the presence of the barrier (20) and the hydrophobic surface (30) as mentioned.
