Definitions

  • the invention relates to a jet shaper, which is arranged in the water outlet of a sanitary outlet fitting and which has at least one homogenizer with a plurality of flow holes, which are each bounded by, flow guide walls.
  • the previously known jet regulators have a homogenizing device which has a honeycomb-like or mesh or net-like structure with a multiplicity of throughflow holes which are delimited by flow guide walls.
  • the homogenizer may optionally be preceded by further functional units on the inflow side.
  • the jet former for generating a flat water jet belt has a greater beam width compared to the beam depth that the at least one homogenizer at least in a partial region in the flow direction nozzle-like tapering flow guide upstream or downstream, and that the flow guide has on both sides of its longitudinal extent edge regions with a larger compared to the longitudinal center region flow area.
  • the beam former according to the invention optionally has a homogenizing device beyond further functional units, which forms a smooth, uniformized jet with a transparent, clear jet pattern with the aid of its throughflow holes delimited by flow guide walls.
  • the homogenizing device is preceded or followed by a flow guide that tapers in the manner of a nozzle, at least in a partial region in the flow direction.
  • this flow guide On both sides of its longitudinal extension, this flow guide has edge regions with a larger flow cross-section than the longitudinal middle region. In the marginal corner areas is respectively generates a high-volume guide beam, these, arranged in the corner regions guide beams are connected by a central jet film together.
  • a water distribution which is inhomogeneous over the jet cross-section is achieved with more or less strong edge stress, wherein the edge stressing can be varied, if necessary, by designing the flow guide and its clear cross section.
  • the flow guide has a bone-shaped clear cross-sectional contour on the outlet side.
  • a preferred embodiment according to the invention provides that in the flow guide a water jet belt can be produced, which has on both sides in the edge regions each have a jet area with increased compared to the longitudinal central area volume flow and between these jet areas a water film connecting them together.
  • jet former The manufacturability of the jet former according to the invention is further simplified if the jet former is detachably insertable into the water outlet and held there, preferably by frictional engagement.
  • the jet former carries on its peripheral wall a circumferential ring seal, which is preferably held in an outer groove of the peripheral wall of the jet former is.
  • a particularly advantageous development according to the invention provides that the flow-guiding walls of the homogenizing device form a lattice- or net-shaped or a honeycomb-cell-like structure.
  • FIG. 2 shows the beam former from FIG. 1 in a longitudinal section in section plane III-III according to FIG.
  • FIG. 3 shows the jet former of FIGS. 1 and 2 in a plan view of its inflow side
  • FIG. 4 shows the beam former from FIGS. 1 to 3 in a cross-section in section plane IV-IV according to FIG.
  • FIG. 5 shows the beam former from FIGS. 1 to 4 in a per- perspective view on its inflow side
  • FIGS. 1 to 5 shows the beam former from FIGS. 1 to 5 in a perspective top view on its outlet side
  • FIGS. 1 to 7 show a beam former 1 in different views. It is clear from the cross section in FIG. 7 that the jet former 1 can be inserted into the water outlet 2 of a sanitary outlet fitting.
  • the beam former 1 has a homogenizer 3, which forms the inflow-side end face of the beam former 1.
  • the homogenizer 3 has a plurality of flow holes 4 which are bounded by flow guide walls 5, respectively. It is clear from FIGS. 1, 3 and 5 to 7 that the flow guide walls 5 form a grid-shaped structure.
  • the jet former 1 has a larger jet width 1 than the jet depth t in order to produce a flat water jet belt.
  • the homogenizing device 3 is followed by a flow guide 6, which narrows in the manner of a nozzle, at least in a partial region in the flow direction.
  • This flow guide 6 has on both sides of its longitudinal extent edge regions 7, 8 with a comparison with Longitudinal region 9 larger flow area on.
  • the homogenizer 3, with the aid of its flow-through walls 4 bounded flow holes 4 forms a smooth, uniform water jet with a transparent, clear spray pattern.
  • the homogenizing device 3 is followed by a flow guide 6, which narrows in the manner of a nozzle, at least in a partial region in the flow direction.
  • this flow guide 6 On both sides of its longitudinal extension, this flow guide 6 has edge regions 7, 8 with a larger flow cross-section compared to the longitudinal middle region 9.
  • a high-volume guide beam is generated in the edge-side corner regions, wherein these guide beams arranged in the corner regions are connected to one another by a central jet film.
  • the beam former 1 shown here a water distribution which is inhomogeneous over the beam cross-section is achieved with more or less strong edge stress, wherein the edge stressing can be varied by designing the flow guide 6 and its clear cross section.
  • the flow guide 6 has a bone-shaped clear cross-sectional contour on the outlet side. It is shown in FIGS. 8 to 10 that the contour of the flow guide 6 can be used to more or less vary the edge stress of the water jet generated in the beam former 1.
  • the jet former 1 can be detachably inserted into the water outlet 2 and held there, preferably by frictional engagement.
  • the beam former 1 contributes its circumferential wall a circumferential annular seal 10, which is preferably held in an outer groove 11 of the peripheral wall of the jet former 1.
  • the homogenizer 3 can be detachably inserted into the beam former 1.
  • the flow guide walls 5 of the homogenizer 3 have a grid-shaped structure.
  • the jet former 1 can be inserted into the water outlet from the outlet side of a sanitary outlet fitting and can be held in a press fit there by means of the annular seal 10.
  • the edge regions 7, 8 two more or less pronounced guide beams are formed, between which then a stable water film can form.
  • the edge-side guide beams and the water film located in the longitudinal center region 9 of the flow guide 6 can vary more or less, which can be achieved by the various "nodular" restriction contours of the beam former 1.
  • the task of the homogenizer provided on the inlet side of the beam former 1 is to use the beam
  • the beam former 1 effectively counteracts an early collapse of the water jet generated therein, with the aid of the beam former 1 providing a smooth radiation surface and a glass clear spray pattern without disturbing turbulences a transparent, clear spray pattern is achievable.
