  • Flush and pre-wash systems are known, for example, with regard to urinals and shower toilets, in which a pre-wash is triggered before use. This contributes to improved hygiene by keeping the siphon, i. H. the odor trap is filled with water once to promote the evacuation of urine. In addition, such a pre-flush also serves to wet the bowl surface of the urinal with water in order to reduce any buildup on the bowl surface.

  • a motor or actuator such as a linear drive or a solenoid
  • a pre-rinse function generally requires little rinse water, because the aim of a pre-rinse is to only wet the bowl of the sanitary facility with water in order to create or leave a sliding layer, and in this way to help reduce the amount of faeces during use and / or urine stick to the bowl of the sanitary facility, so that any second main flushing processes or subsequent cleaning can be avoided.
  • a standard small-volume flush with 3 liters of flushing water, as used according to the current state of the art, is not necessary for this and can objectively be viewed as a waste of water.
  • flushing valves it is not possible to provide quantities of flushing water other than those preset on the flushing valve. This applies both with regard to any desired smaller amounts of flushing water and also with regard to a possibly desired larger amount of flushing water.

  • This variability of the flushing system according to the invention is based on the innovation that the drain valve that closes the drainage of the flushing water into the bowl of the sanitary facility is not only, like conventional drain valves, by a purely mechanical lever-float combination that can be defined by a setting, if necessary , which always results in one or more specific predefined lift height (s) of the drain valve, can be raised and thus opened, but also by means of an actuator that acts on the flushing lever of the drain valve independently of a manual actuation button.

  • the drain valve is opened only briefly and just enough by actuating the small-quantity flushing lever of the drain valve that a small amount of flushing water, sufficient to wet the surface of the bowl, can be dispensed.

  • the actuator is deactivated, whereby the pressure cable is actively or passively pushed back into its starting position before the actuator was activated.
  • “Active” in this context means that the actuator actively pulls the pressure cable back.
  • Passive in this context means that the pressure cable is pushed back into its starting position by the lever mechanism of the closing valve. The valve closure itself takes place in that the valve falls back into its position closing the drain opening due to gravity.
  • valve and drain or flush valve for reasons of simplicity are used both for the part of the drain valve / valve / flush valve closing the drain opening and for the valve as a whole, since the flushing system according to the invention is a known per se Drain valve / valve / flush valve is used, the mechanics and functionality of which is assumed to be known and according to the invention is also used when opening by means of the actuator, the lifting bell of the valve closing the drain opening by the actuator, however, according to the invention in more than that by the conventional drain valve / valve / Flush valve mechanically preset positions and can also be held there if desired.
  • An essential point of the flushing system or pre-flushing system according to the invention is to use an actuator to act on the small flush volume mechanism, for example, so that not the entire small flush volume, but only an amount of flush water sufficient to wet a surface of a bowl of a sanitary facility is delivered to a flushing water tank and distributed in the bowl of the sanitary facility.
  • this is achieved in that, in a conventional mechanical two-flush volume drain valve, the small flush volume mechanism is controlled in such a way that the flush water valve rises to such an extent that a reduced amount of flush water is released compared to the small flush volume, which is just sufficient to prevent faeces from adhering and / or to avoid urine in the bowl of the sanitary facility without the actual small flush volume mechanism specified by the valve becoming active.
  • the surface of the bowl of the sanitary facility is only wetted with water without, as in the prior art, a significant amount of water flowing out of the bowl of the sanitary facility.
  • the actuator is a motor, in particular a linear drive, a spindle drive or a swivel joint mechanism, which acts on the selected flush volume mechanism or lever via a pressure force transmission, for example by means of a pressure cable or a pressure rope, and the drain valve in the event of activation opens so that an amount of flushing water defined by the height of lift of the valve is dispensed into the bowl.
  • a pressure cable is used, which is advantageously passed through a Bowden cable and acts on a lever arm of the small flush volume mechanism.
  • this can cause the smallest amount of flushing water required for pre-flushing to be released into the bowl of the sanitary facility by opening the valve briefly and then dropping it after the actuator has been switched off.

H. Odor trap, has expired.
  • the flushing system according to the invention can have a time control to end activation of the actuator after a predeterminable period of time after activation of the actuator or to reset the actuator to its initial state before the pressure force transmission, so that the drain valve subsequently , ie after deactivation of the actuator, can close again.
  • the setting of a reduced amount of flushing water for example for pre-flushing the bowl of the sanitary facility, is controlled in a surprisingly simple manner via an opening degree, or the lift height, of the drain valve.
  • the degree of opening of the drain valve is adjusted so that the amount of flush water used for pre-flushing is preferably in the range of 20% to 80% of the small flush volume of 3 liters, i.e. in the range of 0.6 liters to 2.4 liters however, depending on whether a flush toilet or a urinal is to be pre-flushed, it is in the range from 1 liter to approx. 1.5 liters, i.e. about half the conventional small flush volume.
