Definitions
- the invention relates to a method for automatically triggering a flushing process for urinals with an electrically operable shut-off valve in the water inlet and a temperature sensor arranged in the odor trap, the signals of which are evaluated by an electronic control and evaluation unit for controlling the shut-off valve.
- a urinal with an automatic temperature-controlled flushing device in which a temperature sensor arranged outside the odor trap triggers a flushing process as soon as it detects a temperature increase due to urine impingement.
- This is intended to avoid the disadvantages which occurred when arranging temperature sensors in the odor trap, in particular because the temperature increase in the odor trap often does not lead to evaluable signals.
- the arrangement of the temperature sensors outside the odor trap does not always lead to the generation of clearly evaluable signals.
- the invention has for its object to 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 and at If a predeterminable minimum value for the temperature gradient is exceeded, a rinsing process is triggered.
- a flushing process is always triggered when the temperature change rate, i.e. the change in the determined temperature over time exceeds a certain, adjustable value, for example by introducing urine or also dirty water. Since the method according to the invention does not record the absolute temperature, but rather the temperature rise over time with the aid of the control and evaluation unit, the invention avoids unnecessary rinsing processes which are caused by an increase or decrease in the absolute temperature detected by the temperature sensor due to heating or cooling the ambient air would arise.
- a relatively small change in the temperature gradient for example a change in temperature of 0.2 ° C per second, is sufficient to trigger the desired flushing process, since such a change in the temperature gradient is not caused by 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. If it is arranged invisibly, there is no need to install visible parts such as light barriers or infrared sensors to trigger the rinsing processes. This reduces the risk of deliberate destruction, which is triggered in particular by recognizing visible control parts.
- a urinal 2 fastened to a wall 1, the water outlet 3 of which is connected to a water supply line 4.
- a water turbine 6, which drives an electric generator 7, is arranged behind a shut-off valve 5.
- the shut-off valve 5 is actuated by an electromagnet 8.
- an odor trap 9 is connected, which ends in a drain line 10.
- a temperature sensor 12 is attached to the odor trap 9, which is protected from access by a cover 11, and is connected to an electronic control and evaluation unit 14 by a signal line 13.
- the energy supply of this electronic control and evaluation unit 14 is provided by a capacitor 15, the charging voltage of which is generated by the electrical energy generated in the generator 7 and which is supplied to the capacitor 15 by a charging line 16.
- the electronic control and evaluation unit 14 is connected to the electromagnet 8 via a control line 17.
- 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 due to the warmer ambient air to the room temperature T1 of, for example, 20 ° Celsius. If at the time t1 urine with a temperature of about 36 ° Celsius is introduced into the urinal 2 and thus into the odor trap 9, the temperature T rises from the value T1 significantly faster than by heating the ambient air to a value T2.
- This rinsing process in turn brings cold water into the odor trap 9, so that the temperature determined by the temperature sensor 12 in the odor trap 9 drops in accordance with the diagram in FIG. 2. Subsequently, the temperature rises slowly due to the warmer ambient air.
- a temperature-proportional signal is generated, which is integrated in the RC element 6.2.
- a switching signal is always triggered by forwarding to comparators 6.3 and 6.4 when the current sensor signal exceeds the switching threshold which results from the integration signal and from electrical coupling of the comparator.
- the averages, comparisons and operations required to trigger the rinsing process are created using a suitable computer program.
- the rule applies that a rinsing process is triggered when the current temperature T is a small amount greater than the average value of the last minutes. Even if the temperature drops by a certain amount in a certain time, a rinsing process is triggered.
