Definitions

  • the present invention relates to a method for automatically actuating the flushing device of a double urinal system with two electrodes arranged in each siphon of the system and connected to an electronic control unit for measuring the conductivity of the flushing water located in the siphon and one in each feed line for the flushing water Solenoid valve, as well as a flushing device for a double urinal system, each with two electrodes arranged in each siphon of the system and connected to an electronic control unit for measuring the conductivity of the flushing water in the siphon and one magnetic valve arranged in each supply line for the flushing water.
  • Double urinator systems are known, in which the flushing process is triggered when the conductivity value measured in the siphon between two electrodes attached in the siphon exceeds an adjustable value.
  • These known systems have the disadvantage that, when the two urinos are used simultaneously or almost simultaneously, the flushing process of both urinos takes place simultaneously at least for a certain part of the total flushing time. As a result, the diameter of the primary rinsing water supply must be too large.
  • this is achieved in that when the flushing process of one urinal of the double urinal system is started, the flushing for the other urinal is blocked during the flushing process and / or when the conductivity falls below a first adjustable value and / or falls below a second adjustable value
  • the rinsing process is interrupted and a fault message is triggered at the same time.
  • control device comprises first means for mutually blocking the flushing for the two urinos and / or second means for switching off the flushing in the event of a fault.
  • this is achieved in the method in that when the value falls below a first adjustable value and / or falls below a second adjustable value of the conductivity of the rinsing water in the siphon, the rinsing process is interrupted after an adjustable number of rinses or after an adjustable time and a fault message is triggered at the same time.
  • control device comprises means for switching off the flushing in the event of a fault.
  • the system comprises two urinals 2 and 3, secondary supply lines 4 and 5 for the rinsing water and a control device 6 for controlling the rinsing of the two urinals 2 and 3.
  • a primary water supply line 7 leads to the control device 6 and to two solenoid valves 8 and 9 which are provided in the control device.
  • Two flexible hoses 10 and 11 lead from the solenoid valves to external connections 12 and 13 on the control device 6 for the secondary feed lines 4 and 5 for the rinse water.
  • two electrodes 16 and 17 are respectively.
  • 18 and 19 for measuring the electrical conductivity of the rinsing water located in the siphons 14 and 15.
  • the electrodes 16 and 17 respectively. 18 and 19 are by electrical leads 20 and 21, respectively. 22 and 23 are connected to the electronic control device 24 located in the control device 6.
  • FIG. 2 shows a section along the line II-II of FIG. 1.
  • FIG. 3a shows schematically the flushing process of a known double urinalir system and in FIG. 3b the flushing process of the double urinalir system according to the invention.
  • the solenoid valve 8 and / or 9 is actuated by the control electronics 24 after a certain delay time and the flushing process is initiated.
  • the control electronics 24 In the known double urinoir system with simultaneous or almost simultaneous use of systems A and B, ie when the impedance between the measuring electrodes 16 and 17, respectively. 18 and 19 below the response value, triggered by the control electronics after the delay time t v, the rinsing process during the rinsing time t s , the delay time being the same for both urinos A and B.
  • Fig. 3b it can be seen how the rinsing process works with simultaneous or almost simultaneous use of the systems A and B with the control device according to the invention.
  • the flushing process is initiated during a time t s even after the control electronics 24 respond to an increased conductivity measured between the electrodes 16 and 17 after a delay time t v .
  • the flushing process is also delayed after the electrodes 18 and 19 respond to a measured increased conductance between them during a delay time t v .
  • the control electronics system B is blocked during time t sp and flushing is initiated at system B during time t s .
  • the primary water supply line 7 can also be equipped with a 1/2 inch pipe. If two double urinals are combined to form a 4-unit system, a 3/4-inch pipe can be selected for the primary supply, whereas a 1-inch pipe would normally be necessary.
  • FIG. 4 shows the block diagram for the control of the double urinal system with mutual flushing lock and lockout.
  • the conductivity measurement in the two siphons 14 and 15 of the double urinoir system takes place via electrodes 16 and 17 respectively.
  • 18 and 19, which each have a measuring arrangement 25 and. 26 are connected to a comparator 27 with a response threshold.
  • the comparator 27 is each with a first circuit 28. 29 connected, which circuits each contain a delay stage, a purge time setting and a lockout circuit.
  • the first circuits 28 and 29 are connected to a second circuit 30, which causes the two urinos A and B to be blocked when one of them is flushed.
  • the second circuit 30 is each with an amplifier and output stage 31 respectively.
  • the components 28 and 29 are a green and red light emitting diode 33 and 34 respectively. 35 and 36 connected. During the retirement light up and during the delay or flushing time of the system A and / or B, the green LEDs 33 flash. 35. In the event of a fault, ie if the resistance between electrodes 16 and 17 resp. 18 and 19 in the siphons 14 and 15 of the urinos A and B is continuously smaller than, for example, 200 ⁇ or continuously larger than, for example, 10 k ⁇ , the red LEDs 34 and 34 light up, respectively. 36.
  • Resistance that is too low can occur, for example, if a piece of money that has fallen into the urinal between the two Electrodes contact, or if the resistance between urine stones between the electrodes has dropped below the above-mentioned interference threshold. If the supply line from the electronic control circuit 24 to the electrodes is interrupted, the resistance between the electrodes is constantly too high, that is to say, for example, greater than the interference threshold of 10 k ⁇ . It would also be conceivable to provide a third light-emitting diode, which shines yellow, for example, if the resistance is too high or too low. If the resistance between the electrodes is constantly too low, the flushing of a urinal is stopped by the circuit 28 or 29 after an adjustable number of flushing processes, for example after five flushing processes.
  • the operator can then use the display means, in this case the light emitting diodes, to determine that a fault has occurred. If, in the event of a fault, the flushing of one urinal was not stopped, firstly the water consumption would be too high, and secondly the flushing of the other urinal of the double urinal system would be permanently blocked. It could also be provided that the control electronics 24 interrupt the rinsing process of a urinal after a settable time in the event of a fault, in all cases this being indicated by the light-emitting diodes in the event of a fault. It would also be conceivable to indicate the fault by means of an acoustic signal.
  • the electronic control circuit 24 could also be constructed, for example, with a one-chip processor, in which case the information relating to the function, that is to say flushing, delay, blocking or malfunction, could then be called up. In this case, only one lamp would be required for each urinoir A, B, which would shine continuously, for example, in normal functioning, would flash twice if the resistance was too low and three times if the resistance was too high.
  • the front plate 37 of the control electronics 24 can be seen.
  • the flushing time for system A or B can be set separately, for example between 2 and 10 seconds.
  • connection 40 and 41 for connection to the network. Furthermore, connections 42 and 43 are respectively. 44 and 45 provided for the solenoid valves 8 and 9. Connections 46 and 47 are provided for electrodes 16 and 17 of urino A and connections 48 and 49 are provided for electrodes 18 and 19 of urino B.
  • the fault lock-out described could also be used in individual urinalir systems.
