Definitions

  • the present invention relates to a jet regulator for a sanitary fitting and a sanitary fitting with a corresponding jet regulator.
  • Sanitary fittings of this type are used in particular to provide a liquid as required at a sink or washbasin.
  • Sanitary fittings can have an aerator through which the liquid can be released as a laminar jet.
  • jet regulators of this type can be designed in the manner of an aerator, through which air can be admixed to the liquid.
  • discharging the liquid as a laminar jet can lead to high liquid consumption.
  • the object of the invention is therefore to at least partially solve the problems outlined with reference to the prior art and in particular to specify an aerator for a sanitary fitting, through which the liquid consumption of the liquid can be reduced. Furthermore, a sanitary fitting with an aerator should be specified, through which the liquid consumption of the liquid can be reduced.
  • the aerator can be used in particular for a sanitary fitting which is used to provide a liquid, in particular water or mixed water, for example at a tap, a sink and/or a washbasin.
  • the mixed water can be mixed by the sanitary fitting or by a mixing valve of the sanitary fitting, in particular from cold water with a cold water temperature and hot water with a hot 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 is in particular a maximum of 90° C., preferably 25° C. to 90° C. more preferably 55°C to 65°C.
  • the mixing valve can be arranged at least partially in a fitting housing of the sanitary fitting. Furthermore, the mixing valve can be actuated via an actuating element, in particular for setting a mixed water temperature of the mixed water and/or dispensing the mixed water.
  • the actuating element can be designed, for example, in the manner of a lever or rotary element.
  • the aerator can be designed, for example, in the manner of a mousseur, an aerator or an aerator and/or can be used to deliver the liquid to an area surrounding the sanitary fitting.
