Abstract

La présente invention concerne un dispositif de nettoyage par ultrasons (50) pouvant purger de manière adéquate de l'eau à partir d'un seau de stockage d'eau (210) et améliorant ainsi la commodité pour un utilisateur. Le dispositif de nettoyage par ultrasons (50) comprend : un orifice de purge (211) pour purger l'eau du seau de stockage d'eau (210) ; un corps de soupape (220) qui ferme l'orifice de vidange (211) ; et un mécanisme de commutation de soupape (230) utilisé pour commuter le corps de soupape (220) de la manière suivante : lorsque le générateur d'ultrasons (110) et le seau de stockage d'eau (210) sont situés dans les positions de fonctionnement, le corps de soupape (220) est dans un état fermé ; et lorsque le générateur d'ultrasons (110) et le seau de stockage d'eau (210) sont situés dans les positions de veille, le corps de soupape (220) est dans un état ouvert. Le mécanisme de commutation de soupape (230) comprend une partie d'actionnement (250) pour ouvrir le corps de soupape (220). Lorsque le générateur d'ultrasons (110) et le tambour de stockage d'eau (210) sont situés dans les positions de fonctionnement et qu'une opération d'ouverture est effectuée, le mécanisme de commutation de soupape (230) commute le corps de soupape (220) d'un état fermé à un état ouvert.
