Domestic appliance

摘要

The appliance has a heating device (2) comprising an electrical non-conductive substrate (5) as support material and an electrical conductive coating (6) arranged on the substrate. The electrical conductive coating is heated in a current-conducting state. The heating device comprises an electrical conductive, porous material (7) heated in a current-conducting state. The substrate comprises glasses, glass fibers, plastic i.e. silicone, and ceramic. The substrate exhibits a porous, foam-like, air-permeable structure.
