Definitions

  • the present invention relates to a sanitary fitting which can be used in particular for sinks, wash basins, showers and/or bathtubs.
  • a liquid in particular water, can be dispensed as required.
  • Sanitary fittings usually have a fitting housing with a rigid or swivelling outlet. An outlet opening is formed on the outlet, through which the liquid can be released as a jet into the area surrounding the sanitary fitting.
  • the disadvantage of the known sanitary fittings, and particularly low-pressure fittings, is that the jet can be inhomogeneous, fluttering and/or splashing when released.
  • the jet pattern can often only be improved by completely opening the sanitary fitting, which, however, leads to increased liquid and/or energy consumption.
  • 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 provide a sanitary fitting through which the liquid can be dispensed with an improved jet pattern.
  • the sanitary fitting is used in particular for the needs-based provision or dosing of a liquid, in particular water, at a sink, washbasin, shower and/or bathtub.
  • the sanitary fitting can be part of a drinking water installation in a building.
  • the sanitary fitting can have a mixing valve for mixing cold water with a cold water temperature and hot water with a hot water temperature 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 is in particular a maximum of 90 °C, preferably 25 °C to 90 °C, particularly preferably 55 °C to 65 °C.
  • the sanitary fitting can have at least one actuating element, for example in the manner of an actuating lever. With the help of the at least one actuating element, in particular the mixed water temperature and/or a discharge amount of the mixed water or the liquid can be adjusted.
  • the hot water can be supplied to the sanitary fitting, for example, from a water heater or a boiler.
  • the flow straightener can have a rectifier length (in particular parallel to the longitudinal axis). of, for example, 5 mm to 50 mm and/or (in particular orthogonal to the longitudinal axis) a straightener diameter of, for example, 10 mm to 50 mm.
  • the flow straightener is in particular not designed in the manner of a mousseur.
  • the flow straightener in particular does not allow air to be mixed into the liquid or mixed water.
  • the flow straightener is in particular designed in such a way that it has a low flow resistance and/or (essentially) does not generate an increase in pressure in a water heater connected to the sanitary fitting.
  • the valve casing tapers in a flow direction of the liquid or the mixed water up to a, in particular slot-shaped, valve outlet.
  • the valve outlet is closed when the sanitary fitting is not in use or the mixing valve is closed. If an inflow of liquid or mixed water is activated, for example by opening the mixing valve, the slot-shaped valve outlet opens due to elastic deformation of the valve casing as a result of the liquid pressure, allowing the liquid or mixed water to pass through the duckbill valve. After the mixing valve is closed, the slot-shaped valve outlet closes automatically as a result of the falling liquid pressure, preventing the liquid from dripping.
  • the duckbill valve is arranged or fixed in the outlet.
  • the channels of the duckbill valve can run parallel to the longitudinal axis.
  • the duckbill valve is arranged upstream of the flow straightener, in particular in the flow direction of the liquid through the outlet.
  • the flow direction of the liquid in the outlet points in particular from the fitting housing to the outlet opening.
  • the duckbill valve is arranged in particular upstream of the flow straightener or the flow straightener downstream of the duckbill valve.
  • the duckbill valve allows the flow straightener to be supplied with liquid or mixed water across its entire cross-section not only when the mixing valve is fully open, but also when the mixing valve is only partially open and/or when the flow of liquid or mixed water through the outlet is low, so that the liquid can be delivered with a homogeneous jet pattern.
  • the duckbill valve expands so that an increase in pressure in the water heater or boiler can be avoided. If liquid is heated in the water heater or boiler, the liquid in the water heater or boiler can expand and lead to droplets forming at the outlet.
  • the duckbill valve can prevent uncontrolled emptying of the outlet.
  • the duckbill valve can be attached to the outlet using a housing of the flow straightener.
  • the housing can be at least partially sleeve-shaped, ring-shaped or tubular.
  • the housing can have an inner diameter of, for example, 10 mm to 50 mm (in particular orthogonal to the longitudinal axis).
  • the housing can have a thread and/or be screwed to the outlet.
  • the housing can be made at least partially of metal and/or plastic.
  • the duckbill valve can, for example, be clamped between the housing and the outlet.
  • the duckbill valve can have a circumferential flange.
  • the flange can serve in particular to fasten the duckbill valve in the outlet.
  • the circumferential flange can be clamped between the housing and the outlet.
  • the flange can have at least one sealing geometry.
  • the at least one sealing geometry can be designed, for example, as annular elevations on the flange.
  • the at least one sealing geometry can prevent the liquid or mixed water from escaping from a gap between the duckbill valve and the outlet and/or between the duckbill valve and the housing of the flow straightener.
  • the Fig.1 shows a sanitary fitting 1 in a side view.
  • the sanitary fitting 1 has a fitting housing 2 with an outlet 4 having an outlet opening 3.
  • the outlet 4 extends from the fitting housing 2 to the outlet opening 3 along a longitudinal axis 21.
  • the outlet 4 is (essentially) U-shaped here.
  • a mixing valve (not visible here) is arranged for mixing cold water and hot water to form mixed water.
  • the mixing valve can be operated via an actuating element 18, which is designed here in the manner of an actuating lever.
  • the mixed water can be fed from the mixing valve via the outlet 4 to the outlet opening 3 and can be discharged via the outlet opening 3 to an area 19 surrounding the sanitary fitting 1.
  • the Fig.2 shows the outlet 4 in a Fig.1 with a circle 20 in a sectional view.
  • a flow straightener 5 is arranged in the outlet opening 3 of the outlet 4.
  • the flow straightener 5 has a plurality of channels 22 which are separated by partitions 23 and extend parallel to the longitudinal axis 21.
  • the flow straightener 5 has (parallel to the longitudinal axis 21) a straightener length 24 and (orthogonal to the longitudinal axis 21) a straightener diameter 25.
  • the straightener diameter 25 corresponds (essentially) to an inner housing diameter 26 of a housing 13 with which the flow straightener 5 is attached to the outlet 4.
  • the housing 13 is sleeve-shaped and screwed to the outlet 4.
  • a first variant of a duckbill valve 6 is arranged upstream of the flow straightener 5 in the outlet 4 (in a flow direction 28 of the mixed water through the outlet 4).
  • the duckbill valve 6 is thus arranged in the outlet 4 upstream of the flow straightener 5.
  • the duckbill valve 6 has a length 32 (parallel to the longitudinal axis 21).
  • the duckbill valve 6 comprises a carrier element 8 and a duckbill valve insert 9.
  • the carrier element 8 is sleeve-shaped.
  • the carrier element 8 consists of a hard material and the duckbill valve insert 9 of an elastic material 12.
  • the duckbill valve insert 9 is connected to the carrier element 8 via a plug connection 10.
  • the duckbill valve insert 9 has cams 29 for forming the plug connection 10, each of which is inserted into a cam receptacle 30 of the carrier element 8.
  • the cams 29 and the cam receptacles 30 extend parallel to the longitudinal axis 21 in the direction of the outlet opening 3.
  • the duckbill valve insert 9 extends in the flow direction 28 from a valve inlet 31 to a slot-shaped valve outlet 17.
  • the valve outlet 17 is at a distance 7 from the flow straightener 5 (parallel to the longitudinal axis 21).
  • the carrier element 8 has an inner diameter 33 in the area of the valve outlet 17.
  • the carrier element 8 comprises a circumferential flange 14 which is clamped between the outlet 4 and the flow straightener 5 by means of the housing 13. The duckbill valve 6 is thereby fastened in the outlet 4.
  • the Fig. 3 shows the flow straightener 5 in a perspective view.
  • the flow straightener 5 has a plurality of prongs 35 on a longitudinal straightener end 34, which are arranged in a circle around the longitudinal axis 21.
  • the prongs 35 make it possible to close the channels 22 of the flow straightener 5, for example by a user of the Fig.1 shown sanitary fitting 1, can be prevented.
  • the Fig.4 shows the carrier element 8 in a sectional view.
  • the flange 14 is formed on a first longitudinal end 36 of the carrier element 8 and has a first sealing geometry 15 and a second sealing geometry 16.
  • the sealing geometries 15, 16 are each formed as annular elevations on the flange 14 and extend in the direction of a second longitudinal end 37 of the carrier element 8.
  • the flange 14 also has a third sealing geometry and fourth sealing geometry (not visible here) on an opposite side.
  • the third sealing geometry and fourth sealing geometry extend in the direction of the first longitudinal end 36 of the carrier element 8 and are arranged mirror-symmetrically to the sealing geometries 15, 16.
  • the cam receptacles 30 are formed in the second longitudinal end 37 of the carrier element 8.
  • the Fig.5 shows the duckbill valve insert 9 in a perspective view and the Fig.6 the duckbill valve insert 9 in a sectional view along the Fig.5 shown cutting plane 27.
  • a valve jacket 38 of the duckbill valve insert 9 extending to the slot-shaped valve outlet 17 has a valve jacket thickness 39.
