Abstract
The invention relates to a device for the automatic release of a flushing process after use of a urinal or similar sanitary appliance. The invention is characterized in that at least one sensor is placed in the trap. When the level of the liquid in the trap changes, the sensor generates a switching impulse which controls a water electrovalve. This causes the water valve to open and flushing to begin
Claims21
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;
- 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.
An apparatus for automatic triggering of a flushing process after usage of a urinal or similar sanitary engineering installation, such as a toilet, wherein at least one target (1.4) is disposed in a water trap (siphon) (1.15) of the urinal exhibiting a feed-in inlet (1.1) and a discharge outlet (1.14), which target changes its position upon level changes (1.13,1.14, 1.5, 2.1,2.2, 2.3) of the liquid contained in the siphon (1.15), and wherein the change in position is captured by a sensor (1.8,1.9), which sensor causes the generation of a switching pulse (1.10) then when the liquid level changes by a predetermined amount, and wherein the switching pulse triggers an electro-water valve or, respectively, a magnet controlled water valve, thereby the opening of the water valve and the initiation of the flushing process is caused, characterized in that a discharge barrier (1.6) is disposed in the discharge outlet (1.14) of the siphon (1.15), wherein the discharge barrier (1.6) is furnished with an opening (3.3), wherein the cross-section of this opening (3.3) is dimensioned such that only a volume stream smaller than the average urine volume per time unit is possible through this opening (3.3) and wherein the target (1.4) is disposed in the region of the discharge barrier (1.6).
