BRIEF DESCRIPTION OF THE FIGURES

[0032] Exemplary embodiments of the present invention are explained in more detail below with reference to figures. These are for explanation only and should not be interpreted restrictively. It shows

[0033] FIG. 1 a multi-volume flushing system toilet according to the invention; and

[0034] FIG. 2 a schematic representation of a sound measurement.

DETAILED DESCRIPTION OF THE INVENTION

[0035] FIG. 1 shows a multi-volume flushing system toilet 1 according to the invention, which comprises a multi-volume flushing system and a toilet bowl 2. The multi-volume flushing system comprises a closable flushing water supply 7, 8 with a flushing water reservoir 7 and a flushing line 8, the flushing line 8 connecting the flushing water reservoir 7 to the toilet bowl 2. The toilet bowl 2 comprises a collecting basin 4 and a siphon 5. A drainpipe 6 is connected to the toilet bowl 2, through which the dirty water can drain into the sewage system. Shown is a toilet bowl 2 mounted on a wall, in which the flushing line 8 and the drainpipe 6 are guided essentially horizontally from behind the wall to the toilet bowl 2. In the area of the flushing water reservoir 7, the flushing line 8 can be completely closed by a flushing process trigger 10. The amount of flushing water can be determined by the duration of the opening of the flushing process trigger. The opening time is determined in a central processor unit CPU 12. The duration of the opening is determined on the basis of vibrations, which can be detected with a vibration detector 16 and can be evaluated with the CPU 12. The CPU 12 is electrically operatively connected to the flushing trigger 10, the vibration detector 16 and a user control 9. The multi-volume flushing system or the CPU 12 is supplied with electrical energy via a power supply. By activating the user control 9, the flushing line 8 can be released by the flushing process trigger 10. The actuation can be done by touch or without contact. For example, a movable push button or a stationary pressure surface can be used as a user actuation 9 with touch. Contactless user actuations 9 can comprise a first area 90 close to the wall or a second area 91 close to the toilet bowl. The first area 90 is arranged near a corresponding marking on the wall. The marking is, for example, a sign with a label or a pictogram. The second area 91 is arranged above and/or in front of the toilet bowl 2. A fan 20 is arranged in the area of the multi-volume flushing system toilet 1.

[0036] FIG. 2 shows a schematic illustration of a sound measurement as it can be visualized by means of an oscilloscope to which a vibration detector 16 can be connected. It is immediately apparent that a liquid 21 causes a signal sequence with a low amplitude and that a solid 22 triggers an individual signal with a much higher amplitude. The introduction of liquids 21 can thus be clearly distinguished from the introduction of solids 22 into the collecting basin 4 of a toilet bowl 2. This is also the case even if the respective total volume is identical.
