Definitions
- the invention relates to a method for automatically triggering a rinsing process for urinals with an electrically operated shut-off valve in the water inlet and a temperature sensor arranged in the odor trap, whose signals from an electronic control and evaluation unit Control of the shut-off valve can be evaluated (see DE-U-9 012 652).
- U1 is a urinal with an automatic temperature-controlled Flushing device known, in which an outside of the odor trap arranged temperature sensor triggers a rinsing process as soon as this one Temperature increase detected by urine.
- This is supposed to Disadvantages are avoided that when arranging temperature sensors in the Odor trap occurred in particular because the temperature increase often does not lead to evaluable signals in the odor trap.
- the arrangement of the temperature sensors outside the odor trap does not lead to the generation of clearly evaluable signals in all cases.
- the invention has for its object to further develop the method described above for automatically triggering a flushing process for urinals such that reliably evaluable signals for triggering a flushing process are generated under all operating conditions with at least one temperature sensor arranged in the odor trap.
- control and evaluation unit uses the values supplied by the temperature sensor to determine the temperature gradient, that is to say the change in the determined temperature over time, and initiates a rinsing process when a predetermined minimum value for the temperature gradient is exceeded becomes.
- the method according to the invention is independent of the respective absolute temperature in the odor trap and also with slow temperature changes due to the warming or cooling of the ambient air a flushing process is triggered whenever the temperature change rate, i.e. the change in the determined temperature over the Time exceeds a certain, adjustable value, for example by Discharge of urine or also dirty water. Since with the invention Process not the absolute temperature, but the temperature rise over time with the help of the control and evaluation unit is avoided the invention unnecessary rinsing operations by an increase or Lowering of the absolute temperature detected by the temperature sensor arise due to heating or cooling of the ambient air would.
- a relatively small change in the Temperature gradients for example a temperature change of 0.2 ° C per second to trigger the desired rinsing process, as such
- the temperature gradient does not change due to heating or Cooling of the ambient air, but only by introducing Urine or dirty water can be caused.
- the temperature sensor in the odor trap of the urinal i.e. installation is invisible, the installation is omitted visible parts, such as light barriers or infrared sensors to trigger the Flushing. This reduces the risk of deliberate destruction, especially by recognizing visible control parts to be triggered.
- shut-off valve 5 is a water turbine 6, which is an electric generator 7 drives.
- the shut-off valve 5 is actuated by an electromagnet 8th.
- an odor trap 9 connected, which ends in a drain line 10.
- a temperature sensor 12 attached by a signal line 13 with an electronic Control and evaluation unit 14 is connected.
- the energy supply this electronic control and evaluation unit 14 is carried out by a Capacitor 15, the charging voltage generated by the generator 7 electrical energy is generated, the capacitor 15 by a Charging line 16 is supplied.
- the electronic is via a control line 17 Control and evaluation unit 14 connected to the electromagnet 8.
- the temperature and gradient in the odor trap 9 is determined by the control and evaluation unit 14 on the basis of the values supplied by the temperature sensor 12.
- the diagram according to FIG. 2 shows the temperature curve over time t with solid lines. It can be seen that after a previous rinsing process the water temperature of, for example, 12 ° Celsius slowly rises to room temperature T 1 of, for example, 20 ° Celsius due to the warmer ambient air. If urine at a temperature of approx.
- circuit 6.1 shown in Fig. 3 is a temperature proportional Generated signal that is integrated in the RC link 6.2.
- a switching signal is always triggered at comparators 6.3 and 6.4, if the current sensor signal exceeds the switching threshold, which turns out the integration signal and by electrical positive feedback of the comparator results.
- a microprocessor those for triggering the Averaging, comparisons and operations required for the flushing process created using a suitable computer program. The following applies on the one hand the rule that a rinsing process is triggered when the current temperature T is a small amount larger than the average value the last few minutes. Even if the temperature is in a certain Time decreases by a certain amount, a rinsing process triggered.
