Abstract

Un robinet comprend un bec, un conduit deau qui transporte leau à travers le bec et un mécanisme actionnable par voie électrique disposé dans le conduit. Un premier capteur capacitif a un premier champ de détection et produit un premier signal de sortie à la détection des mains dun utilisateur dans ce premier champ de détection. Un deuxième capteur capacitif a un deuxième champ de détection qui produit un deuxième signal de sortie à la détection des mains dun utilisateur dans ce deuxième champ de détection. Un dispositif de commande se couple aux premier et deuxième capteurs capacitifs et au robinet actionnable par voie électrique. Le dispositif de commande est programmé pour actionner le robinet actionnable par voie électrique par suite de la détection des mains de lutilisateur dans le premier champ de détection, mais pas dans le deuxième champ de détection, pendant un intervalle prédéterminé qui commence dès la détection des mains de lutilisateur dans le premier champ de détection.
