Abstract

Selon l'invention, une pompe puise une eau de bain depuis un orifice d'absorption d'eau. Un conduit commun communique avec la pompe, et un conduit de partie supérieure bifurque depuis ce conduit commun. Un orifice d'évacuation d'eau de partie supérieure communique avec le conduit de partie supérieure, et décharge l'eau puisée par la pompe. Un conduit de partie inférieure bifurque également depuis le conduit commun. Un orifice d'évacuation d'eau de partie inférieure communique avec le conduit de partie inférieure, et décharge l'eau puisée par la pompe. Une vanne de commutation fait communiquer le conduit de partie supérieure et/ou le conduit de partie inférieure. L'orifice d'évacuation d'eau de partie supérieure est positionné dans une partie supérieure par rapport au point de bifurcation du conduit commun, et l'orifice d'évacuation d'eau de partie inférieure est positionné dans une partie inférieure par rapport à l'orifice d'évacuation d'eau de partie supérieure. Un dispositif de commande de vanne émet des signaux de commande vers la vanne de commutation, et met en communication le conduit de partie inférieure avec le conduit de partie supérieure afin de guider l'eau restant dans le conduit de partie supérieure vers le conduit de partie inférieure lorsque le fonctionnement de la pompe est à l'arrêt.
