Definitions

  • the invention relates to a water outlet mouthpiece for the water outlet of a faucet according to the preamble of patent claim 1.
  • a water outlet mouthpiece in particular for a household water pipe is known, in which the water inlet side, a filter element is arranged. Behind this filter element two nozzle plates are provided, each having cylindrical passage openings which are arranged offset to one another. With the nozzle plates, the water is divided into a plurality of individual jets, which mix in a subsequent mixing chamber with sucked air and are summarized in a subsequent sieve package back to a full, the water outlet mouthpiece leaving mixed jet.
  • Water outlet mouthpieces of the type mentioned are from the DE 102 46 333 A1 and the DE 100 27 986 A1 known. These each have successively arranged, spaced-apart water-carrying elements, which throttle the water flow, expand and shape and each have approximately the same cross-sectional area.
  • the object of the invention is to provide a device of the type mentioned above in such a way that the water jet without the use of an air mixer or aerator water outlet side evenly distributed to a plurality of outlet openings to obtain a homogeneous spray pattern of multiple water jets.
  • the water outlet mouthpiece comprises a carrier element which can be connected to the water outlet and has an antechamber.
  • the flow rate of the incoming water jet is reduced with the throttle element to obtain a laminar flow.
  • the water jet is then widened evenly with the at least one expansion elements and further slowed down.
  • the exiting water jet is formed by the mold element. Since the water flows with reduced flow rate almost turbulence-free through the water outlet mouthpiece, and beyond no air supply is provided, takes place in the water outlet mouthpiece no mixing with air.
  • the throttle element, the expansion element and the mold element are arranged on or in the carrier element.
  • the carrier element has an inlet nozzle, whose cross section is substantially smaller than the cross section of the vestibule.
  • a water pipe between a mixer valve or the like and the water outlet nozzle can be used with a relatively small internal cross-section, which takes a correspondingly smaller amount of water.
  • a relatively quick water exchange in the water pipe can be achieved, so that when changing the setting of the mixer valve a rapid change in temperature and / or change in water quantity, so a quick feedback at the water outlet takes place.
  • This is particularly important in electronically controlled mixer valves of great importance, since an operator is dependent on this feedback.
  • the high flow velocity due to the small internal cross section of the water pipe does not have the consequence here, in contrast to the prior art, that turbulences in the water outlet lead to an inhomogeneous spray pattern.
  • the elements are each arranged at a distance from one another. This has the advantage that, following each element, a sufficiently large volume is available into which the water can be distributed without turbulence.
  • the at least one throttle element is a baffle arranged in the antechamber of the water outlet mouthpiece substantially perpendicular to the water flow direction.
  • the baffle plate has flow openings along its edges.
  • a water outlet with a smaller inner cross-section with which a faster water supply is made possible by a mixing valve to the water outlet nozzle.
  • the at least one expansion element as a perforated plate, in particular as a perforated plate, with a plurality of particularly evenly over the respective perforated plate arranged holes can be realized, which is arranged in front of a respective expansion space.
  • At least two perforated plates are arranged one behind the other essentially parallel to one another, whose holes are offset, so that the water, after flowing through the holes of one of the perforated plates, is decelerated at the respective non-perforated region of the next perforated plate viewed in the direction of flow, and thus the flow rate is further reduced to achieve a calming of the water flow and an even better distribution of the water.
  • the molding element has a plurality of through-flow of the molding channels, to which the water is split, and with which the desired spray pattern is realized.
  • the molding element is a cuboid with continuous cylinder bores.
  • the use of a cuboid has the advantage that arranged along its long sides a plurality of cylinder bores can be, so that a composite of a plurality of individual shape jets water curtain can be generated.
  • the water outlet mouthpiece has a substantially an outer cross-section of the same formula elements inner cross-section, so that a uniform expansion of the water jet over the entire flow area in the water outlet nozzle is made possible before the mold element.
  • the support element in particular a housing, can be clipped.
  • the inlet connection is designed for connection to a hose, with which the water outlet nozzle can be connected to a water hose in the interior of the fitting leading to the mixing valve.
  • the fitting itself does not come into contact with water. In this way it is prevented that deposited in the valve lime or the interior of the valve corroded.
  • FIG. 1 a water outlet nozzle 1 is arranged in a water outlet 2 with a rectangular cross section of a faucet.
  • Mixing valve connected water hose 3 is water inlet side in the FIG. 1 from above on a tubular inlet port 4 of the water outlet mouthpiece 1 inserted.
  • the inlet nozzle 4 is arranged centrally in a front side of a housing 5 of the water outlet mouthpiece 1.
  • the housing 5 is a cuboid, in cross-section to the water outlet 2 complementary hollow body, in the FIG. 1 is opened down and used as a support member for the components described in more detail below.
  • the entrance 4 opens into an anteroom 6 in the housing 5.
  • the vestibule 6 has perpendicular to the course of the inlet nozzle 4 has a rectangular cross-section whose area is substantially larger than the surface of the inner cross section of the water hose 3.
  • the inlet port 4 opposite side of the vestibule. 6 is bounded by a flat baffle plate 7, which is arranged parallel to the end face of the housing 5 and whose outer cross section coincides with the inner cross section of the housing 5.
  • the baffle plate 7 has flow openings 8 along its edges, through which water from the antechamber 6 in FIG. 1 can flow down into a first expansion space 9.
  • the flow openings 8 have the shape of halves along their respective axis cylinders whose cut surfaces terminate with the respective edge of the baffle plate 7.
  • the first expansion space 9 is in FIG. 1 bounded below by a first flat perforated plate 10, which is arranged parallel to the baffle plate 7.
  • a plurality of through holes 11 are arranged in the form of cylinder bores.
  • the edge of the first perforated plate 10 merges into a first sleeve 12, which extends equally upwards and downwards and downwards.
  • the outer cross section of the first sleeve 12 coincides with the inner cross section of the housing 5.
  • the holes 11 of the first perforated plate 10 open into a second expansion space 13.
  • the second expansion space 13 is limited in the figure below by a second perforated plate 14.
  • the second perforated plate 14, analogous to the perforated plate 10, has a multiplicity of through holes 15, which resemble the holes 11.
  • the holes 15 are arranged offset relative to the holes 11, so that the holes 11, 15 of each of the two perforated plates 10, 14 are each a non-perforated region of the other perforated plate 14, 10 are arranged opposite.
  • the edges of the second perforated plate 14 go, analogous to the edges of the perforated plate 10, in a second sleeve 16 on.
  • the outer cross section of the second sleeve 16 also coincides with the inner cross section of the housing 5.
  • the holes 15 of the second perforated plate 14 open into a third widening space 17, which is bounded on the water outlet side in the figure below by a shaped element 18.
  • the mold element 18 has the shape of a cuboid, which is arranged in a form-fitting manner in the housing 5, so that one of its surface pairs is oriented parallel to the second perforated plate 14.
  • three identical mold channels 19 are arranged for three water jets equidistant side by side.
  • the molding channels 19 are continuous cylinder bores whose cylinder axes are oriented perpendicular to the perforated plates 10,14 and lead out of the water outlet mouthpiece 1 out.
  • FIG. 2 the water outlet side of the water outlet mouthpiece 1 is shown. Through the molding channels 19 through the perforated plate 14 can be seen with a portion of their holes 15.
  • FIG. 3 on the right, the components of the water outlet mouthpiece 1 are shown isometrically in an exploded view.
  • the housing 5, the baffle plate 7, the first perforated plate 10, the second perforated plate 14 and the mold element 18 are each viewed from below.
  • the water flows at reduced speed through the passage openings 8 into the first widening space 9, where it distributes in the direction of the center of the first perforated plate 10.
  • the water flows through the holes 11 of the first perforated plate 10 into the second expansion space 13, where the flow velocity is reduced again and an expansion of the original water jet over the entire cross section of the second perforated plate 14 is achieved.
  • the homogeneous laminar water flow now flows evenly to the mold channels 19 of the mold element 18, with each of which a jet of water is formed, so that water outlet side three homogeneous water jets from the mold element 18 of the water outlet mouthpiece 1 emerge.
  • the water outlet mouthpiece 1 is connected directly to the water outlet of the faucet in this case.
  • the water outlet mouthpiece 1 is plugged into the water hose 3 or the water outlet, clipped or screwed.
  • cross sections instead of rectangular cross sections, other cross sections, such as square or oval cross sections may be provided.
