Abstract
A steam generating device including an evaporation chamber for evaporating a liquid which is delivered from a reservoir while the chamber is being heated, which chamber includes a base composed of: a body of thermally conductive material having an upper surface against which the liquid to be evaporated is directed, the body having a surface layer extending from the upper surface; and hydrophilic fibers distributed across the upper surface and at least partially and locally embedded in the surface layer. A process for producing a base of an evaporation chamber, the base being composed of a body of thermally conductive material having an upper surface, the process being composed of intimately binding fibers of thermally insulating, hydrophilic material with the body of thermally conductive material in a layer at the upper surface, and at least partially impregnating the fibers with the thermally conductive material in order to promote heat transfer from the base to liquid which is present on the upper surface in order to evaporate the liquid.
