Abstract

L'invention concerne un appareil chauffant, en particulier un four de cuisson, qui comprend un dispositif d'autonettoyage par pyrolyse. Cet appareil présente une chambre de traitement (4), qui peut être fermée par une porte (9). Entre la face intérieure de porte (13) et un rebord (5) entourant la chambre de traitement (4) est placé un élément d'étanchéité (7) qui est constitué de matières résistant de façon différente aux températures élevées. La partie (14) dudit élément d'étanchéité résistant le plus aux températures élevées fait face à la chambre de traitement (4), et la partie (15) dudit élément d'étanchéité résistant le moins aux températures élevées est opposée à la chambre de traitement (4). Selon l'invention, au moins la partie (14) intérieure de l'élément d'étanchéité (7), qui fait face à la chambre de traitement (4), et la partie extérieure (15) de l'élément d'étanchéité (7), qui est opposée à la chambre de traitement, sont constituées de matières du même type qui présentent une surface fermée et étanche.
