Definitions

  • the invention relates to a water outlet mouthpiece for the water outlet of a Was ⁇ faucet with at least one expansion element for the water flowing through.
  • 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 zylinder ⁇ shaped 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 again to a full, the water outlet mouth ver ⁇ let mixing beam.
  • the object of the invention is to design a device of the type mentioned above such that the water jet can be distributed uniformly to a plurality of outlet openings on the water outlet side without the use of an air mixer or air bubbler in order to obtain a homogeneous spray pattern from a plurality of water jets.
  • the flow velocity of the incoming jet of water with the throttle element is reduced in order to obtain a laminar flow.
  • the jet of water is then mixed with the at least one expansion element.
  • the exiting water jet is formed by the mold element. Since the water flows through the water outlet mouthpiece with virtually no turbulence at a reduced rate of flow and, moreover, no air supply is provided, no mixing with air takes place in the water outlet mouthpiece.
  • a water line between a mixer valve or the like and the water outlet mouthpiece can be used with a relatively small internal cross-section, which takes a correspondingly smaller amount of water. In this way, a relatively quick water exchange in the water pipe reachable, 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.
  • 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 disperse without turbulence.
  • the at least one throttle element is a baffle plate arranged essentially perpendicular to the water flow direction in an antechamber of the water outlet mouthpiece.
  • the baffle plate has flow openings along its edges.
  • a water outlet with a smaller internal cross section ein ⁇ settable with the faster water supply from a mixing valve to the water outlet nozzle is made possible.
  • the at least one widening element can be realized in a particularly simple manner and without great technical complexity as a perforated plate, in particular as a perforated plate, with a multiplicity of holes arranged in particular evenly over the respective perforated plate, which is arranged in front of a respective widening 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 flows through the holes of one of the perforated plates at the respective non-perforated region of the perforated plates Viewed flow direction brakes next perforated plate, and thus the flow velocity is further reduced, to Chen a calming of the water flow and an even better distribution of the water to Errei chen.
  • the molding element has a plurality of mold channels through which water can flow, to which the water is divided, 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 a multiplicity of cylinder bores can be arranged along its long sides, so that a water curtain composed of a multiplicity of individual molding jets can be produced.
  • the Wasserauslaufmund ⁇ piece has a substantially an outer cross-section of the same element equivalent 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 at least one throttle element, the at least one expansion element and the mold element can be connected to one another or in a carrier element which can be connected to the water outlet, in particular be clipped, in particular in a housing.
  • the carrier element has an inlet connection for connection to a hose, with which the water outlet nozzle can be connected to a hose in the interior of the valve, which leads to the mixing valve.
  • the fitting itself does not come into contact with water in this way. In this way it is prevented that limescale settles in the fitting or the interior of the fitting corrodes.
  • FIG. 1 schematically, in section, a water outlet mouthpiece for a tap with a rectangular internal cross section
  • FIG. 2 shows a water outlet-side view of the water outlet mouthpiece shown in FIG. 1;
  • FIG 3 shows the components of the water outlet mouthpiece shown in Figure 1 in isometric view and in each case in a plan view.
  • a water outlet mouthpiece 1 is arranged in a water outlet 2 with a rectangular cross-section of a water tap.
  • One with a not shown Mixing valve connected water hose 3 is inserted on the water inlet side in Figure 1 from above on a rohrförrnigen input port 4 of the water outlet in piece 1 ge.
  • the inlet nozzle 4 is arranged centrally in an end face of a housing 5 of the water outlet end piece 1.
  • the housing 5 is a cuboid, in cross-section to the water outlet 2 complementary hollow body which is opened in the figure 1 un ⁇ th and is 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 agrees.
  • the baffle plate 7 has flow openings 8 along its edges, through which water from the antechamber 6 in FIG. 1 can flow downwards into a first widening space 9.
  • the through-flow openings 8 have the shape of cylinders which are halved along their respective axis and whose cut surfaces are flush with the respective edge of the baffle plate 7.
  • the first expansion space 9 is limited in Figure 1 below by a first flat perforated plate 10, which is arranged parallel to the baffle plate 7.
  • a multiplicity 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 widening space 13.
