Abstract

La présente invention concerne un dispositif et un procédé de rinçage de cuvette de toilettes capables de rendre compatibles une capacité d’évacuation plus élevée et un effet d’économie d’eau plus élevé. Le dispositif de rinçage de cuvette de toilettes comprend un moyen d’alimentation en eau qui introduit de l’eau de rinçage dans la cuvette (2) d'une cuvette de toilettes (1), un passage d'écoulement d'évacuation (5) formé dans la continuité du côté aval de la partie étanche à l'eau (4) de la cuvette de toilettes (1), un moyen d'aspiration de l'air qui aspire l'air du passage d'écoulement d'évacuation (5) et un moyen de commande permettant de commander le moyen d’alimentation en eau et le moyen d’aspiration de l’air. Ce dernier comprend un éjecteur (21) dans lequel une pression négative est produite lorsqu'on fait passer l'eau de rinçage dans celui-ci, un réservoir (20) stockant une pression négative produite lorsque l'éjecteur (21) aspire l’air dans celui-ci, un tuyau d’aspiration de l’air permettant au réservoir (20) de communiquer avec le passage d’écoulement d’évacuation (5) et une valve (V5) installée dans le tuyau d’aspiration de l’air, qui est ouverte et fermée par le moyen de commande.
