Definitions

  • the present invention relates to a sanitary fitting that can be used in particular for washbasins, showers and/or bathtubs.
  • the present invention relates to a method for installing a corresponding sanitary fitting.
  • Sanitary fittings serve in particular to provide water and/or to mix cold water and hot water to form mixed water with a desired mixed water temperature and to dose the mixed mixed water.
  • the water from a valve or the mixed water from a mixing valve is routed via liquid channels in a fitting housing to an outlet opening of an outlet of the fitting housing. Since the water is in contact with the fitting housing, fitting housings must be made of a material suitable for drinking water, such as brass.
  • the liquid channels within the fitting housing must be designed in the form of plastic water channels, for example, so that the mixed water does not come into contact with the fitting housing.
  • connection between a water supply of the outlet and a valve housing of the valve or a valve adapter of the valve or the mixing valve of the sanitary fitting is particularly problematic here, because the connection either involves an increase in the diameter of the fitting housing or a multi-part design of the fitting housing requires.
  • Sanitary fittings with a connecting element for connecting the water supply to the valve adapter are therefore known, with the connecting element being able to be fastened to the valve adapter by means of a linear sliding guide.
  • An O-ring is placed between the connector and the valve adapter to prevent leakage. When assembling the connector to the valve adapter via the linear slide, the O-ring may come out of place due to friction between the O-ring and the connector Position slipping so that its sealing effect is no longer given and there may be delays in assembly due to necessary rework.
  • the object of the invention is therefore to at least partially solve the problems described with reference to the prior art and in particular to specify a sanitary fitting that is easy to assemble and in which a connection between the connecting element and the valve adapter is reliably protected against leaks.

  • the proposed sanitary fitting serves in particular to provide water, to mix cold water and hot water to form a mixed water with a desired mixed water temperature and/or to meter the mixed mixed water.
  • Such sanitary fittings are regularly used for sinks, washbasins, showers and/or bathtubs.
  • the sanitary fitting has a fitting housing with an outlet having an outlet opening, it being possible for the fitting housing to consist at least partially of brass, a zinc alloy and/or plastic.
  • the fitting housing is in particular designed in one piece, d. H. especially not composed of two (half) shells.
