Definitions

  • the invention relates to a backflow barrier which has a jet nozzle which can be connected to an inlet and a catching part which has to capture the liquid jet coming from the jet nozzle via a free jet path and which can be connected or connected to a drain, and with an outlet arranged below the free jet path, which outlet has to discharge a liquid subset not captured by the catching part.

  • Below the jet section located between the jet nozzle and the trapping part there is arranged a housing outlet which has to discharge an amount of liquid, not trapped by the trapping part, out of the housing interior.
  • the pressure energy of the inflowing water from the supply network in the jet nozzle is converted into kinetic energy to bring the water jet on the short free jet distance to the atmosphere in combination and subsequently to at least partially convert the kinetic energy of the water jet in the area of the trapping part, also referred to as a diffuser, into pressure energy which is required, for example, for the cleaning jet of the sub-showers.
  • the jet nozzle and the capture part are to be adapted to each other and to the specific conditions of the respective supply network . It is a disadvantage that the prior art backflow barriers are indeed optimized in view of the prevailing conditions in a particular supply network, but that these backflow barriers may not provide optimal performance under different conditions. It is always effective to ensure that the pipe network is not contaminated with dirty water.
  • the optimized coordination between the jet nozzle and the catching part can be impaired if, in particular, dirt or calcium deposits form on the nozzle opening of the catching part. Such lime deposits are possible if the water droplets remaining at the nozzle opening of the jet nozzle evaporate and a lime residue originally contained in the water remains behind.
  • the achievement of this object is in the backflow barrier of the type mentioned in particular in that the jet nozzle is displaceably guided in the backflow barrier and displaced from a standby position into a spraying position, in which injection position the jet nozzle with its nozzle orifice delimiting a nozzle section Through opening pierces, which is provided in an elastic membrane or closed in the ready position by a flap.
