Flushing arrangement for flushing a toilet bowl, water closet having such a flushing arrangement and toilet bowl

Abstract

The flushing arrangement has a flush tank ( 28 ), from which an amount of flushing water can be supplied to the toilet bowl ( 6 ). Said amount of flushing water is divided into two part amounts for cleaning an upper region of the toilet bowl ( 6 ) and a further part amount for moving water that is present in the toilet bowl ( 6 ). A flushing eddy is generated with one of these two part amounts, said flushing eddy flowing along an inner surface ( 10 ) of the toilet bowl ( 6 ) and cleaning said toilet bowl at least in one upper region (A). There are preferably four part amounts provided which are in each case deliverable in a controlled manner by a valve ( 30, 31, 32, 80 ). The flushing arrangement makes a more thorough cleaning of the toilet bowl possible with comparatively little water.
