  • These valve devices or valves which are installed in the valve devices, typically have a cold water connection and a hot water connection on one side and a mixed water outlet on the other side.
  • Such valve means may comprise a hydraulic single-lever mixer, such as in WO 2006/098795 disclosed.
  • valves that can be controlled by means of an electrical control to open or close them.
  • a control signal generator for generating an input signal to the controller can be used, wherein the controller controls the valves due to the input signal accordingly.
  • WO 2009/019731 A discloses a device for mixing water and regulating the flow rate of service water in hydraulic systems.
  • the apparatus comprises an electronic board or circuits electrically connected to one or more solenoid valves for regulating the flow rate of hot and cold water, the water being delivered to one or more faucets.
  • the relative displacement of one or more magnets in relation to one or more magnetic linear and / or rotational sensors of the electronic circuit generates a potential difference.
  • the potential difference is correspondingly transmitted to the solenoid valves for full / partial hope of this.

  • an electrically controllable valve is installed, which can be operated in two different modes. In one In manual mode, the valve is open and the mixing water flow rate and mixing water temperature are controlled only by the manually operated single lever mixer. In a second mode, the mixed water flow rate and the mixed water temperature are preset by the manually operable single lever mixer, and the electrically controllable valve may be either fully open or fully closed.
  • the controller receives an input signal from a touch or environment sensor when an object (such as a hand) is near the sensor. This input signal causes the controller to send an "on” or “off” flip-flop signal to the valve, which in turn causes the valve to be fully closed or fully opened, and the water flow to be opened or closed accordingly.
  • An object of the present invention is to provide a sanitary fitting with a control signal generator, wherein both mixing water temperature and water flow rate can be adjusted by means of the control signal generator and the control signal generator is only electrically connected via an electrical control with the valve device.

  • the mixed water flow rate is changed at the same mixed water temperature.
  • the electric controller 28 also controls the proportional valves 24, 26 of the valve device 12.
  • the first proportional valve 24 and the second proportional valve 26 are activated such that both valves are opened either by a first and a second opening value (in the case of increasing the mixing water flow rate) or by a first and closed a second closing value (in case of a reduction of the mixed water flow rate).
  • the percentage opening ratio of the first proportional valve 24 to the second proportional valve 26 is always kept constant in order to keep the mixed water temperature at an approximately constant temperature value.
  • FIG. 4b the same applies analogously to the example in FIG. 4b ,
  • FIG. 4b is initially constant by operation of the control signal generator 32 for approximately 1.2 seconds generates a third water quantity plus signal 92.
  • a fourth water quantity plus signal 94 is pulsed for about 0.1 seconds and after about 1.9 seconds (and an interruption of about 0.27 seconds) for about 0.35 seconds a constant fifth water quantity plus signal 96 generated.
  • a second water quantity minus signal 98 becomes constant for about 1.2 seconds and after 4.2 seconds (after an interruption of about 0.5 seconds) a fifth water quantity minus signal 100 pulses generated for around 0.1 seconds.
  • the percentage value of the mixed water flow rate increases within 0.9 seconds with a delay of the duration of the water amount plus time value linear from 0% to approx. 30%.
  • the fourth pulsed water amount plus signal 94 (whose signal duration is also shorter than the stored water amount plus time value) causes the water flow percentage to be instantaneous with respect to the end of the water amount plus signal 94 and 30% within 0.15 seconds 80%, according to the upper mixed water flow limit, increases.
  • the renewed, fifth water quantity plus signal 96 of about 0.36 seconds duration further increases the mixed water flow rate to about 92%.
  • the input signal 30 is no longer compared to a time value, but directly converted and there is therefore no lead time.
  • the input signal 30 is implemented immediately.
  • the second Water amount minus signal 98 of about 1.2 seconds causes the water flow to decrease linearly to about 62% starting with a delay corresponding to the water amount minus time value.

  • the temperature change, with pulse-type input signals 30, takes place at a speed of 100% in 0.5 seconds and, in the case of continuous input signals 30, at a speed of 100% in 2 seconds, and the change in the water quantity in the case of pulse-type input signals 30 at a speed of 100% in 0.3 seconds and, with continuous input signals 30, at a speed of 100% in 3 seconds.
  • speed values can be selected differently by appropriate programming of the controller 28.
  • input signals 30 which are less than or equal to the relevant time value are evaluated as pulse-type signals. However, it is also possible to regard only input signals 30 which are smaller than the relevant time value as pulse-like signals.
  • the controller 28 may be programmed such that, for example, for the above-described mixed water temperature reset value, not the minimum value but any other value is selected. It is also conceivable that several Intermediate stages, both in the temperature setting as well as the mixed water flow rate, can be preset, which can be selected by pulse-like tapping the control signal generator 32 (for example, when increasing the mixing water flow rate not only 30% and 80%, but for example 30%, 50%, 70 % and 80% and for example not only 100% for the mixed water temperature, but for example 20%, 40% 60% 80% and 100%).
  • FIGS. 3a to 3c and 4a and 4b show traces of mixed water temperature and mixing water flow rate as a function of sequential water flow plus, water flow minus, temperature plus or minus temperature input signals. These are generated by the control signal generator 32 or the joystick 34, wherein the actuating lever end region 40 of the joystick 34 can be deflected in two mutually at least approximately perpendicular Auslenkebenen.
  • the four input signals can be combined in any order, so that the temperature can be changed, for example with running water, and then the mixing water flow rate can be changed at the newly set temperature value or vice versa.
  • control signal generator 32 does not consist of a joystick 34, but, for example, four push buttons, each push button each one of the four input signals (water quantity plus, water quantity minus, temperature plus or minus temperature Signal) is assigned.
  • the timer further has the task of detecting the duration of the unaltered mixed water flow by measuring the time during which no more 30 input water flow occurs during a mixed water flow greater than zero. After a certain flow time of a few minutes, the controller 28 automatically sets the flow to zero.
