Definitions

  • Sanitary fitting with a mixed water channel formed between a water conduit and a cartridge receptacle The present invention relates to a sanitary fitting which is used in particular for sinks, shower and / or bathtubs.
  • Sanitary fittings are used to mix cold water and hot water to a mixed water with a desired mixed water temperature and the dosage of the mixed mixed water.
  • the mixed water is passed from a Mischkartu cal via fluid 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, the fitting housing must be made of a material suitable for drinking water, such as brass. Inexpensive zinc housings cannot be used for health reasons, for example. Furthermore, in known sanitary fittings, the fitting housings can become very hot, so that there can be a risk of scalding.
  • 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 which is designed such that inexpensive materials can be used for its fitting housing.
  • a sanitary fitting contributes to this, which has at least the following components: a fitting housing with an outlet having an outlet opening;
  • a cartridge receptacle which is at least partially tubular and arranged in the valve housing Ar;
  • a mixing cartridge for mixing cold water and hot water to form mixed water which is at least partially arranged in the cartridge receptacle;
  • a water duct which is at least partially tubular and in which the cartridge receptacle with the mixing cartridge are at least partially arranged, so that a mixed water channel is formed between the water duct and the cartridge receptacle through which the mixed water can be fed to the outlet opening of the outlet.
  • the proposed sanitary fitting is used in particular to mix cold water and hot water to form mixed water with a desired mixed water temperature and / or to meter the mixed mixed water.
  • Such sanitary fittings are regularly used for sinks, sinks, showers and / or bathtubs.
  • the sanitary fitting has a fitting housing with an outlet having an outlet opening, wherein the fitting housing can at least partially consist of brass, a zinc alloy and / or plastic.
  • the fitting housing can be attached to a support, for example a work plate, the sink, the washbasin, the shower or the bathtub.
  • the fitting housing has a (protruding or branching) outlet which is rigidly or movably connected to the fitting housing.
  • the outlet can be at least partially tubular.
  • the fitting housing can have a decorative outer surface.
  • the outlet has an outlet opening through which a liquid, in particular (mixed) water, can be dispensed.
  • a cartridge receptacle for receiving and / or fastening a mixing cartridge to the fitting housing is arranged in the fitting housing.
  • the cartridge receptacle is at least partially tubular so that the mixing cartridge can be arranged at least partially in the cartridge receptacle.
  • the cartridge receptacle can thus be designed, for example, in the manner of an adapter, by means of which the mixing cartridge is held in the fitting housing.
  • the cartridge holder can at least partially consist of brass and / or plastic.
  • the cartridge receptacle can be attached to the fitting housing directly or indirectly, for example, by other components of the sanitary fitting.
  • the mixing cartridge in particular cold water with a cold water temperature and warm water with a warm water temperature can be mixed to form mixed water with a desired mixed water temperature.
  • the cold water temperature is in particular a maximum of 25 ° C (Celsius), preferably 1 ° C to 25 ° C, particularly preferably 5 ° C to 20 ° C and / or the hot water temperature in particular a maximum of 90 ° C, preferably 25 ° C to 90 ° C, particularly preferably 55 ° C to 65 ° C.
  • the mixing cartridge is at least partially arranged in the cartridge mount and / or attached to the cartridge mount. In addition, the mixing cartridge can be actuated by means of a lever of the sanitary fitting.
  • the mixed water temperature and / or a discharge amount of the mixed water can be set by means of the lever.
  • the mixing cartridge can be designed, for example, in the manner of a single-lever mixer and / or at least partially cylindrical. Furthermore, the mixing cartridge can have a cartridge housing.
  • the sanitary fitting comprises a water duct which is also at least partially tubular.
  • the water duct can at least partially consist of brass and / or plastic.
  • the cartridge receptacle is at least partially arranged with the mixing cartridge in the water duct, so that a mixed water channel is formed between the water duct and the cartridge receptacle.
  • the mixed water channel is particularly in shape a gap formed between the cartridge receptacle and the water guide.
  • the cartridge receptacle can have an outside diameter in the area of the mixed water channel, for example, which is smaller than an inside diameter of the water duct in the area of the mixed water channel.
  • the mixed water channel can be at least partially delimited by an outer surface of the cartridge receptacle and / or an inner surface of the water duct.
  • the mixed water channel can, for example, have a length (in particular in a longitudinal direction parallel to a longitudinal axis of the fitting housing) of 10 mm (millimeters) to 100 mm.
  • the mixed water mixed by the mixing cartridge can be fed to the outlet opening of the outlet via the mixed water channel without the mixed water coming into contact with the fitting housing.
  • the fitting housing can at least partially consist of a material, such as plastic or zinc, which is not suitable for drinking water, which results in a cost advantage.
  • the risk of scalding can be reduced as a result.
  • the mixed water channel can be at least partially ring-shaped.
  • the cartridge receptacle can have a first wall thickness of a maximum of 5 mm in the area of the mixed water channel.
  • the first wall thickness can have 1 mm to 5 mm.
