Definitions

  • the invention relates to a sanitary insert unit, which can be mounted in the water outlet of a sanitary outlet fitting, with a flow rate regulator unit which has at least one annular throttle body made of elastic material in at least one annular flow channel, which has at least one throttle body between itself and an adjacent one which carries a control profile Channel wall delimits a control gap, the passage cross-section of which can be changed by the throttle body, which deforms under the pressure difference that forms during flow, and with a jet regulator arranged on the outflow side of the flow rate regulator unit, which has a jet splitter, which divides the water coming from the flow rate regulator unit into a A large number of individual beams are divided.
  • a sanitary insert unit of the type mentioned at the beginning which includes an inflow-side flow rate regulator unit and a downstream-side jet regulator. While the flow rate regulator unit has to regulate the amount of water flowing through per unit of time to a set maximum value, the water in the jet regulator is formed into a homogeneous, non-splashing and pearly-soft water jet.
  • the flow rate regulator unit has two annular flow channels arranged concentrically to one another, in each of which an annular throttle body made of elastic material is inserted.
  • the throttle bodies each delimit a control gap between themselves and a control profile which is provided on an adjacent channel wall of the associated flow channel, the passage cross section of which can be changed by the throttle body which deforms under the pressure difference that forms during flow.
  • the downstream side arranged jet regulator has a jet splitter which is designed as a diffuser and has a baffle surface which deflects the incoming water radially outwards towards an annular wall.
  • this ring wall there are flow holes distributed over the circumference of the wall, through which the deflected water is divided into individual jets. These flow holes open into an annular gap that narrows in the flow direction and creates a negative pressure on the outflow side. This negative pressure allows ambient air to be sucked into the insertion housing of the previously known insertion unit, where it is mixed with the water flowing through on the outflow side of the diffuser serving as a jet splitter.
  • jet regulators with a jet splitter designed as a diffuser can be used advantageously, especially in a certain area of application, especially at low water pressures.
  • the jet splitter of the jet regulator used in the previously known insertion unit has a central hole-free baffle surface, which is delimited on the inflow-side end face of the jet splitter by an outer first annular wall, which has passage openings oriented in the radial direction and passing through it, on the side arranged in the baffle plane
  • the through-openings each have a flow hole connected to the through-openings through the jet splitter.
  • the outer first annular wall is surrounded on the outer circumference by an annular annular space.
  • the water coming from the flow rate regulator is in the DE 10 2013 004 076 A1 known insertion unit is first deflected radially outwards on the central hole-free baffle surface in order to flow there through the passage openings provided in the inner ring wall into the associated flow hole of the jet splitter, the water flowing from the flow rate regulator unit of the previously known insertion unit cannot flow directly and flow unchecked through the flow holes in the jet splitter and the jet splitter flows out DE 10 2013 004 076 A1
  • the previously known sanitary insertion unit acts more like a conventional diffuser, in which the incoming water on the inflow side of the jet splitter is also initially deflected outwards at right angles to the flow direction of the jet regulator.
  • the flow rate regulator connected upstream on the inflow side DE 10 2013 004 076 A1 The previously known sanitary insert unit has only one annular flow channel, the projection of which is aligned in the flow direction with the hole-free baffle surface. This combination should make the amount of water flowing through the aerator practically independent of the water pressure prevailing in front of the aerator.
  • the jet splitter is designed as a perforated plate
  • the projection of at least one of the flow channels is arranged in a hole-free ring zone of the jet splitter, and that the flow channels are arranged outside the projection of the flow channels
  • Flow holes of the jet splitter designed as a perforated plate are arranged on at least one circular path in the perforated plate in such a way that the water flowing from the flow rate regulator unit flows directly and unbraked through these flow holes in the jet splitter.
  • the insertion unit according to the invention can be mounted on the water outlet of a sanitary outlet fitting.
  • the insertion unit has an inflow-side flow rate regulator unit, on the outflow side of which a jet regulator is provided. While the flow rate regulator unit has to regulate the amount of water flowing through per unit of time to a fixed maximum value regardless of pressure, the jet regulator of the insertion unit according to the invention is intended to form the water emerging there into a homogeneous, non-splashing and possibly also pearly-soft water jet.
  • the flow rate regulator unit of the insertion unit according to the invention has at least one annular flow channel in which an annular throttle body made of elastic material is provided.
  • the throttle body located in the at least one flow channel delimits a control gap between itself and an adjacent channel wall having a control profile, the passage cross section of which can be changed by the throttle body which deforms under the pressure difference that forms during flow.
  • the one located on the downstream side of the flow rate regulator unit The aerator has a jet splitter, which divides the water coming from the flow rate regulator unit into a large number of individual jets. This beam splitter is designed as a perforated plate in the insertion unit according to the invention.
  • the projection of at least one of the flow channels in a hole-free ring zone of the jet splitter is arranged.
  • a hole-free ring zone is therefore provided in the jet splitter in the axial extension of at least one of the flow channels.
  • the flow holes arranged outside the projection of the flow channels in the jet splitter designed as a perforated plate are arranged on at least one circular path in the perforated plate in such a way that the water flowing from the flow rate regulator unit can flow directly and unbraked through the flow holes in the jet splitter.
  • the insertion unit according to the invention is characterized by an advantageous mode of operation even over large and in particular higher pressure ranges.
  • an advantageous embodiment according to the invention provides that at least one flow hole is provided in the central region of the jet splitter delimited by the projection of the at least one flow channel.

  • a preferred embodiment according to the invention which is characterized by particularly good functionality, provides that the flow holes of the jet splitter have an inflow hole section and an outflow hole section. While the inflow hole section can taper in a funnel shape in the flow direction, it is advantageous if the outflow section has a cylindrical clear hole cross section.
  • the functional operation of the insertion unit according to the invention and its flow rate regulator unit is favored if a throttle body with a smaller cross section, in particular a smaller cord thickness, is provided in the flow channel having a smaller diameter, compared to that in the one on the outside, which has a larger diameter Throttle body located in the flow channel.
  • a sanitary insert unit 1 which can be mounted on the water outlet of a sanitary outlet fitting.
  • the insertion unit 1 has an insertion housing 2, which carries a radially projecting annular flange 3 on the circumference in its inflow-side edge region.
