CA 2589357

A plumbing fixture includes a receptacle (12) for receiving waste, a tank (17) for storing water, and an electrically operated pump (22) that conveys water from the tank into the receptacle to flush the waste through a drain. The duration that the pump in operated to flush the waste is altered in response to variation of the electrical voltage supplied to the plumbing fixture. The pump is operated to decrease the amount of water in the tank when that amount is sensed to be excessive. Further operation of the pump is inhibited for a given interval to avoid overheating when the pump has been operating too frequently. The pump is cycled on and off in predefined patterns to indicate different malfunctions to a user.

Cette invention concerne une installation sanitaire comprenant une cuvette pour déchets, un réservoir de stockage d'eau et une pompe électrique faisant passer l'eau du réservoir dans la cuvette pour en chasser les déchets via une vidange. La durée de fonctionnement de la pompe de chasse d'eau varie en fonction des variations de la tension électrique fournie à l'installation sanitaire. La pompe réduit le volume de l'eau dans le réservoir lorsque ce volume est jugé excessif. Par ailleurs, la pompe est coupée pendant un laps de temps donnée afin d'éviter une surchauffe lorsqu'elle a été actionnée trop souvent. Tout mauvais fonctionnement est signalé par des cycles de sollicitation et d'arrêt de la pompe selon une fréquence prédéfinie.
