Abstract

L'invention concerne un connecteur d'entrée de chauffe-eau électrique sans fil, conçu pour être couplé à un connecteur de base complémentaire, sur 360 degrés de rotation relative entre l'appareil et sa base, et conçu également pour être fixé centralement sur le dessous de l'élément chauffant de l'appareil, cet élément étant de préférence un élément à film épais. Deux dispositifs de commande de surchauffe d'élément chauffant, intégrés au connecteur d'entrée, sont logés dans des poches formées sur le pourtour d'un corps en plastique moulé du connecteur. Selon une variante, chaque dispositif de commande se présente sous la forme d'un interrupteur bimétallique soutenu par un support métallique à ressort dont une partie est intégrée à un mécanisme déclencheur d'interrupteur à basculement brusque depuis une position centrale. Selon une autre variante, un dispositif de commande comprend un fusible. La réinitialisation du ou des dispositifs de commande bimétalliques s'effectue lorsque l'utilisateur soulève l'appareil depuis la base et le repose sur celle-ci. Le dispositif de commande à fusible maintient le fusible sous la tension du ressort : ainsi, lorsque le fusible fond en cas de surchauffe, le ressort se détend et entraîne l'ouverture rapide d'une série de contacts d'interrupteur. Enfin, un détecteur de vapeur peut être couplé directement au connecteur.
