  • Patent number: 8726544
    Abstract: A boiler having a shell enclosing a space and an inlet for letting water into the shell space. The shell space has two separate sections, wherein a first section is located such as to receive a supply of fresh water to the boiler and wherein a second section is located such as to receive water from the first section when overflow of the first section takes place under the influence of a continuous supply of fresh water. A steam generating process takes place in the second section. Due to the fact that the second section is only indirectly filled with water, it is possible to have an undisturbed process. In particular, the water may be heated in the first section before reaching the second section. The first section may for example include an inner space of a container which is arranged inside the shell, for example.

  • 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.

  • Publication number: 20110265354
    Abstract: In a boiler (6) having a shell (8) enclosing a space (11) and an inlet (12) for letting water into the shell space (11), the shell space (11) has two separate sections (16, 21), wherein a first section (16) is located such as to receive a supply of fresh water to the boiler (6), and wherein a second section (21) is located such as to receive water from the first section (16) when overflow of the first section (16) takes place under the influence of a continuous supply of fresh water. A steam generating process takes place in the second section (21). Due to the fact that the second section (21) is only indirectly filled with water, it is possible to have an undisturbed process. In particular, the water may be heated in the first section (16) before reaching the second section (21). The first section (16) may comprise an inner space of a container (15) which is arranged inside the shell (8), for example.

  • Patent number: 7920778
    Abstract: A boiler (1) for heating water to steam comprises a boiler housing (10) having a bottom wall (12), a top wall (13) and a circumferential wall (14) extending between these walls (12, 13). When the boiler (1) is mounted in a steam generating device for generating steam and supplying steam to an appliance such as a steam iron (20), the boiler (1) is given an inclined orientation. In a lower portion (13a) of the top wall (13) of the boiler housing (10), an inlet opening (15) for letting in water to a boiler space (11) which is enclosed by the boiler housing (10) is arranged. When water is supplied through the inlet opening (15), the water lands on a lower zone (14a) of the circumferential wall (14) and flows further in a downward direction, along the circumferential wall (14). As a result, the water is pre-heated when it reaches the water which is already present in the boiler space (11), and there is no danger of the steam production getting interrupted.
