Abstract

La présente invention concerne une cuvette de WC à garde d'eau modifiable. Cette cuvette comprend une zone supérieure, une sortie de drainage des déchets de la zone supérieure, une zone inférieure et une sortie de drainage des déchets de la zone inférieure. Un passage de décharge de déchets de dérivation est fixé à une tige support ou un orifice support. Un appareil de repositionnement permet de repositionner le passage de décharge de déchets dont l'extrémité inférieure entoure la sortie de drainage des déchets de la zone supérieure et l'extrémité supérieure pouvant être abaissée et repositionnée automatiquement et amenée jusqu'à la sortie de drainage des déchets de la zone inférieure. L'invention vise à remédier aux inconvénients de la cuvette de WC classique dus à l'immobilité du passage de décharge de déchets entre la sortie de drainage de déchets de la zone supérieure et la sortie de drainage de déchets de la zone inférieure, ces inconvénients étant une garde d'eau élevée, une résistance de l'eau élevée et une grande consommation d'eau. Le passage de décharge de déchets selon l'invention est dévié automatiquement pour former une garde d'eau plus basse lorsque l'on tire la chasse-d'eau et il est repositionné automatiquement pour former une garde-d'eau plus haute lorsque l'on ne tire pas la chasse d'eau. Cela permet non seulement de piéger les odeurs mais aussi d'améliorer l'efficacité de la chasse-d'eau et d'économiser l'eau. La structure selon l'invention est simple, fiable et a un faible coût.
