Abstract

La présente invention concerne un dispositif de lavage des mains avec lequel des dysfonctionnements d'un distributeur de liquide de lavage peuvent être évités pendant le lavage des mains sans nécessiter une structure de dispositif complexe. Un dispositif de lavage des mains 1 comprend : un distributeur d'eau 10 qui distribue de l'eau ou de l'eau chaude lorsqu'un objet est détecté ; et un distributeur de liquide de lavage 20 qui distribue un liquide de lavage. Le distributeur d'eau 10 comprend : un orifice de distribution d'eau 12 ; un capteur de distribution d'eau 11 qui détecte un objet dans une plage de détection ; et une unité de commande de distribution d'eau 16 qui commande la distribution/coupure d'eau ou d'eau chaude depuis l'orifice de distribution d'eau 12 sur la base d'un signal de détection du capteur de distribution d'eau 11. Le distributeur de liquide de lavage 20 comprend : un orifice de distribution 22 ; un capteur de distribution de liquide de lavage 21 qui détecte un objet dans une plage de détection ; et une unité de commande de distribution de liquide de lavage 28 qui commande la distribution/coupure du liquide de lavage depuis l'orifice de distribution sur la base d'un signal de détection du capteur de distribution de liquide de lavage. Une direction de capteur Y2, qui est une direction d'émission de lumière d'émission qui est émise depuis le capteur de distribution de liquide de lavage 21, est inclinée une direction de distribution plus loin vers le bas qu'une direction de distribution X1 d'eau ou d'eau chaude qui est distribuée depuis l'orifice de distribution d'eau 12.
