Abstract

L'invention concerne un dispositif de nettoyage sanitaire et un dispositif de toilette qui permettent d'éliminer efficacement les saletés d'une buse de nettoyage ou d'un dispositif analogue. Ce dispositif de nettoyage sanitaire est installé dans une partie fonctionnelle de la cuvette de toilette et a pour fonction de nettoyer le corps humain, et comprend : une buse de nettoyage (51) pouvant se déplacer vers l'avant et vers l'arrière entre une position fermée et une position avancée ; et une partie de nettoyage de buse (53) qui projette de l'eau de lavage pour nettoyer la buse de nettoyage (51). Le débit de l'eau de lavage projetée par la partie nettoyante de la buse (53) est plus élevé que le débit de l'eau de lavage projetée par la buse de nettoyage (51).
