The invention relates to a heating device (1) comprising a metallic substrate (2) whose at least one part is coated with a self-cleaning coating. The inventive coating consists of an external layer (4) contacting ambient air and comprising at least one type of oxidation catalyst selected from platinoid oxides, at least one internal layer (3) which is arranged between the metallic substrate and the external layer and comprises at least one type of oxidation catalyst selected from transition elements oxides of lb group. The inventive heating device can be embodied, for instance in the form of an iron soleplate consisting of a heating base (6) provided with heating elements (7) or a cooking appliance. Said metallic substrate can be covered with an intermediary enamel layer (5). A method for coating the metallic substrate of a heating device with said coating is also disclosed.
La présente invention concerne un appareil chauffant (1) comprenant un support métallique (2) dont au moins une partie est recouverte d'un revêtement autonettoyant, caractérisé en ce que le revêtement comprend: - a~) une couche externe (4), au contact de l'air ambiant, comprenant au moins un catalyseur d'oxydation choisi parmi les oxydes de platinoïdes, - b~) au moins une couche interne (3), située entre le support métallique et la couche externe, comprenant au moins un catalyseur d'oxydation choisi parmi les oxydes des éléments de transition du groupe lb. Cet appareil chauffant peut par exemple être sous la forme d'une semelle de fer à repasser comprenant une base chauffante (6) munie d'éléments chauffants (7) ou d'un appareil de cuisson. Le support métallique peut être recouvert d'une couche intermédiaire (5) en émail. L'invention concerne également un procédé pour recouvrir le support métallique d'un appareil chauffant d'un revêtement tel que décrit ci-dessus.
