Abstract:
An apparatus for automatic triggering of a flushing process after usage of a urinal or similar sanitary engineering installation comprising a urinal;a water trap disposed in the urinal; a target disposed in the water trap of the urinal exhibiting a feed-in inlet and a discharge outlet, wherein the target changes its position upon level changes of the liquid contained in the water trap and wherein the target is disposed on a discharge side of the water trap; a sensor disposed in the water trap for capturing a change in position of the target, wherein the sensor causes the generation of a switching pulse when the liquid level changes by a predetermined amount; a water valve connected to the sensor, wherein the switching pulse triggers the water valve, thereby the opening of the water valve and initiating a flushing process; a discharge barrier disposed in the discharge outlet of the water trap, wherein the discharge barrier is furnished with an opening, wherein the cross-section of this opening is dimensioned such that only a volume stream smaller than the average urine volume per time unit is possible to pass through this opening and wherein the target is disposed in the region of the discharge barrier; a barrier immersed in the water trap in such a way that no air exchange is possible between the region of the feed-in inlet and the discharge outlet, but a flow through of liquid is possible.
