  • the annular grooves 84 take in the assembled state lock washers 85 for reliable attachment of the bracket 82.
  • the mixing valve according to the invention in contrast to the known from the prior art mixing valves with manual adjustment of the temperature mixing device, the possibility to make an automatic hygiene flush. This is ensured by the fact that at the beginning of an automatic hygiene flush when opening the solenoid valve 23, the mixing valve 3 can be moved by means of the drive 25 in an open position, which may differ from the random setting of the temperature by the last user. This is ensured by the fact that the drive 25 is in communication with the adjusting device 7, which adjusts the mixer shaft in the predetermined position for a hygiene flush. Depending on the programming, this may be a mix of cold and hot water to ensure that both the cold water line and the hot water level are flushed out with a single flush.
  • the solenoid valve 23 is opened to allow the entry of water into the mixing valve according to the invention. After expiration of the preset purge time, the solenoid valve 23 is closed. It can be provided that the mixing valve moves after the predetermined flushing time in a preprogrammed position. Alternatively, it can also be provided that the mixing valve remains in the last rinsing position. Of course, there is the Possibility to specify different flushing times depending on the respective opening positions during programming.
  • a bracket by front or bevel gears.
  • the use of a belt drive is basically possible here.
  • a thermostat can also be used.
  • the invention opens up the possibility of providing an automatic hygiene flush also on fittings which are provided with a manual mixing device.
  • the mixing fitting according to the invention offers the possibility of arranging the components used also in an electronic washstand fitting of conventional size. Consequently, the mixing fitting according to the invention can be combined with conventional assemblies known from the sanitary sector, without having to make a change to other assemblies here.
  • the mixing fitting according to the invention is capable of independently carrying out so-called hygienic rinsing.
  • the controller 20 has a time measuring device, in which a time interval is adjustable, after which a forced flushing of the mixing valve according to the invention is to take place. If the mixing valve is not used within the pre-set period of time, an automated hygiene rinse takes place. This is done by a signal emitted by the controller 20, which is directed to the drive 25. The drive 25 comes into operation as a result of this signal, which leads to a movement of the drive shaft lever 77, which in turn via the bracket 82 has a movement of the mixer shaft lever 70 result.
  • the drive 25 is in operation until the mixer shaft 49 has reached an open position in which 17 enters the mixing valve 1 from both the hot water connection pipe 18 and from the cold water connection pipe 17.
  • this is the middle position, ie the position in which equal amounts of cold and warm water flow through the valve.
  • the opening position initially provides a cold water flushing and then provides a hot water flushing, or vice versa.
  • the mixer shaft 49 is moved to a mixed water position.
  • the solenoid valve 23 is controlled and released the inlet of the mixing valve 1, so that water can enter the valve.
  • both the cold water line and the hot water line are flushed by the design according to the invention, whereby a contamination of the upcoming in the lines of water is avoided.
  • the controller 20 Upon expiration of a pre-programmed purge time in the controller 20, in which the water flows through the mixing valve, the controller 20 again sends out a signal that causes the solenoid valve 23 to close. There is then no more water in the valve on and off.
  • the programming of the controller 20 may provide that the mixing valve 3 or the thermostat is brought by closing the solenoid valve 23 by means of the drive 25 in a predetermined opening position of the cold and / or hot water supply. Regardless of this, the next flushing operation will either occur when a user activates the mixing fixture or once again oversteps the preset period of non-use, again performing a forced sanitary flush as described above.
  • a mixing valve is provided which allows a forced flushing of the mixing valve to avoid stagnant water despite manual temperature setting and this simultaneously realized in a housing having the dimensions of conventional mixing valves.
  • Such a solution is not known from the prior art.
