Abstract

La présente invention concerne un appareil chauffant d’un chauffe-eau électrique instantané. L’appareil comporte un caisson rayonnant la chaleur possédant une admission d’eau et une évacuation d’eau. Un capot rayonnant la chaleur est monté à l’entrée d’une extrémité dudit caisson rayonnant la chaleur et une feuille en céramique destinée à rayonner la chaleur est solidement rattachée à l’extrémité inférieure du capot rayonnant la chaleur. L’extrémité de sortie de ladite feuille en céramique destinée à rayonner la chaleur est raccordée aux lignes d’alimentation électrique qui traversent ledit capot rayonnant la chaleur. Une fois montée, la feuille en céramique est immergée dans le liquide contenu dans ledit caisson rayonnant la chaleur. La feuille en céramique destinée à rayonner la chaleur est constituée d’un corps de feuille en céramique et d’une couche mince imprimée destinée à rayonner la chaleur, laquelle est agglomérée dans ledit corps de feuille en céramique par frittage. La présente invention dotée de cette structure a l’avantage d’offrir une structure simple, une haut rendement thermique, un rayonnement uniforme de la chaleur et une longue durée de vie.
