Definitions

  • the invention relates to a drinking water pipe system with a cistern

  • the aim is to ensure perfect drinking water quality in the respective drinking water installation.
  • Microorganisms and, under certain circumstances, pathogens such as legionella can multiply in drinking water installations. If legionella get into installations with heated drinking water where the water temperature is between 25 °C and 50 °C, they can multiply to hygienically relevant concentrations.
  • the quality of the drinking water in the pipes and devices of a drinking water installation can be adversely affected, particularly as a result of stagnation and unsuitable operation, due to the proliferation of microorganisms or an increased concentration of dissolving parts of the materials of the devices or pipes, so that the requirements placed on drinking water are no longer met .
  • a well-known measure for maintaining a hygienic drinking water quality is to provide a drinking water circulation line, the heated drinking water a drinking water heater, z. B. a storage drinking water heater, in which the drinking water to a minimum temperature of z. B. about 60 ° C is heated.
  • a further known measure for maintaining hygienically perfect drinking water quality consists in arranging a flushing station at the end of a water pipe run, for example at one end of a drinking water floor pipe of a residential building or hospital.
  • the rinsing station enables cold and/or hot water to be drained off in a targeted manner into a drain in order to enable the water in the respective water line harness to be exchanged.
  • a drinking water pipe system in which a cold water pipe is designed as a series pipe.
  • the cold water pipe shows at least one tap valve serving as an extraction point and an outlet, a toilet cistern being connected to the outlet, and the cistern being arranged at the end of the cold water line.
  • the drinking water pipe system is equipped with an electronic controller that is equipped with a time measuring device and uses a sensor to record drinking water withdrawal from the cold water pipe, with the sensor activating the time measuring device and the electronic controller when drinking water is withdrawn controls an actuating device of the cistern to trigger a toilet flush when a predetermined time interval since the last drinking water withdrawal is exceeded.
  • the same quantity of cold water is always taken from the cold water pipe for flushing at the same maximum time intervals.
  • the cistern comprises a flushing device with a cold water supply line, a hot water supply line, a valve arrangement for letting in the water flowing in through the cold water supply line and the hot water supply line, and a water discharge line for draining the water let in by the valve arrangement.
  • the flushing device has at least one temperature sensor for measuring the water temperature in the cold water supply line and/or the hot water supply line and for generating at least one temperature signal.
  • a controller for actuating the valve arrangement is provided.
  • the controller generates a control signal as a function of the temperature signal, with the valve arrangement draining water through the water drain into the cistern as a function of the control signal.
  • the cistern is provided with a cistern valve arrangement, by means of which at least part of the amount of water contained in the cistern can be drained for flushing a toilet.
  • the cistern is also, as is customary in the prior art, provided with an overflow which does not require the draining of water from the cistern which rises above a predetermined water level in the cistern Actuation of the cistern valve assembly is used.
  • the overflow is defined by a valve closure body of the cistern valve arrangement designed as an overflow pipe.
  • this cistern allows not only a hygiene flushing of a cold water line but also a hygiene flushing of a hot water line, the respective hygiene flushing does not take place independently of the flushing water level. With hygiene flushing, the safety distance of the overflow water level prescribed in DIN EN 14055 is not reached by the mark for the highest nominal water level to be applied by the cistern manufacturer.
