Abstract

L'invention concerne un dispositif de nettoyage sanitaire (50) capable de réaliser le nettoyage de buse avec une configuration peu coûteuse et simple sans réduire la facilité d'utilisation des fonctions de nettoyage. En mode « maintien d'interruption de chaleur », pendant lequel la mise sous tension d'un chauffage d'eau chaude est interrompue pendant une durée donnée grâce à l'actionnement d'une unité d'actionnement (52), durant cette période l'eau chaude dans le réservoir d'eau chaude (20) est projetée par un dispositif de nettoyage de buse d'une ouverture de sortie d'eau de nettoyage de buse (151) ou d'un système similaire, et le dispositif buse (100) est nettoyé. Par conséquent, il est possible d'utiliser efficacement l'eau chaude dans le réservoir d'eau chaude (20) et de maintenir l'hygiène du dispositif buse (100) et il est possible d'éviter de diminuer la facilité d'utilisation à cause de l'absence d'eau chaude lors du prochain nettoyage localisé.
