  • Publication number: 20160273757
    Abstract: The present invention discloses a steam generator for a steam oven in particular used to evaporate water for the purpose of food preparation. The configuration in an L-shape combined with an inner profile maximizing the heat transfer surface increases the power density and facilitates limestone removal during heating and cooling of the steam generator (500). The configuration acts as a natural drain for debris that is generated during operation. By mounting the longer arm (502) of an L-shaped steam generator in a horizontal position and corresponding dimensioning of the heat transfer area, optimum conditions for household appliances can be achieved. A sup port structure (530) fixes the steam generator (500) in such a position in the household appliance (600).
