Definitions

  • the invention relates to a sanitary insert unit, which can be inserted into a discharge fitting, comprising an essentially conical-shaped upstream sieve with a downstream throughflow regulator and a jet regulator located further downstream in the direction of the flow.
  • Sanitary insert units of the type mentioned at the outset have been known in various embodiments. Such insert units are regularly inserted into a discharge mouthpiece, which is mounted in a detachable manner in a sanitary discharge fitting. With the aid of such insert units, a homogenous, soft, and non-splashing water jet is formed.
  • Such insert units comprising an upstream throughflow regulator and a downstream jet regulator, can result in mounting problems due to their construction size.
  • the retrofitting into such discharge fittings is problematic, which had previously been operated with an insert unit comprising no throughflow regulators but a jet regulator only, because the latter insert unit has a lower construction height than the insert unit with a throughflow regulator.
  • the object is to provide a sanitary insert unit of the type mentioned at the outset, in which the mounting problems based on the construction height are avoided even in environments with limited space.
  • the object is attained according to the invention in particular in that the throughflow regulator is essentially arranged within the interior space of the insert unit limited at its top by the upstream sieve.
  • the insertion of the throughflow regulator into the interior space limited by the upstream sieve can occur in a particularly efficient manner, when the throughflow regulator is provided with a cross-sectional profile essentially shaped corresponding to the profile of the upstream sieve.
  • the upstream sieve can become clogged by contaminants or calcium deposits.
  • the throughflow regulator In order to ensure sufficient water flow even in upstream sieves partially clogged in their central area it is advantageous for the throughflow regulator to be provided with a sloping surface rising radially upward at an exterior, in particular circular edge region, which leads to a throughflow opening connected to a control gap or the like, provided with the jet regulator, and for the rising sloping surface and the upstream sieve to be distanced from one another.
  • the rising sloping surface In order to achieve a defined flow of water to the throughflow regulator via the rising sloping surface and to avoid turbulence in the circumferential direction, it is useful for the rising sloping surface to be provided on its upper side with approximately radially aligned grooves to form individual inflow channels.
  • the inflow speed can be increased at the throughflow regulator, and subsequently at the jet regulator as well, so that the functionality of the insert unit is improved.
  • the bars located between the grooves to end close to or at the interior side of the upstream sieve and to serve as support elements for said upstream sieve. This way, the bars form supports for the upstream sieve so that the stability of the arrangement is improved and an undesired deformation of the upstream sieve, for example by excessive pressure of the inflowing water, can be avoided.
  • the bars of the rising sloping surface In order to enable steady water influx it is useful for the bars of the rising sloping surface to be distanced from one another in regular intervals in the circumferential direction.
  • One preferred embodiment of the insert unit according to the invention includes the throughflow regulator being provided with a central core region, which is surrounded by a circular throttle body, and that between the throttle body and the rising sloping surface a control gap is formed, with the cross-section of its opening being adjustable by the throttle body deforming under the pressure difference developing by the throughflow.
  • FIG. 1 a side view of an insert unit according to the invention, partially in cross-section
  • FIG. 2 a top view of the throughflow regulator of an insert unit according to the invention.
  • a sanitary insert unit marked 1 in its entirety, is provided with an upstream sieve 2 , a throughflow regulator 3 , and a jet regulator 4 , detachably connected to one another via its housing.
  • FIG. 1 shows a side view of the insert unit 1 partially in a cross-section.
  • the upstream sieve 2 formed essentially cone-shaped, an interior space 6 is formed, in which the throughflow regulator 3 is arranged.
  • the throughflow regulator 3 is provided with a central core region 7 , which is surrounded by a circular throttle body 8 . Between the throttle body 8 and a radially, inwardly rising sloped surface 9 a control gap 10 is formed in the exterior edge region of the throughflow regulator 3 , which is in throughflowing connection to the jet regulator 4 located therebelow.
  • the central core region 7 , the throttle body 8 , and the rising sloping surface 9 are sized such that the cross-sectional profile of the throughflow regulator 3 is substantially form-fitting to the cross-sectional profile of the upstream sieve 2 , with the rising sloping surface 9 and the upstream sieve 2 being distanced from one another. Due to the arrangement of the throughflow regulator 3 inside the interior space 6 formed below the upstream sieve 2 an insert unit 1 results with, in reference to conventional insert units, a reduced construction height and/or with the ability to realize a construction height for an insert unit housing a throughflow unit, which previously was only possible for insert units without any throughflow regulators. Thus, the insert unit 1 according to the invention can be easily integrated in environments, in which previously known jet regulators without any throughflow regulators had been used or which are provided with limited space available.
  • the rising sloped surface 9 is provided at its upper side with rinsing grooves or the like 11 , extending radially and equally spaced apart from one another, in order to form individual influx channels.
  • These influx channels allow a controlled incoming flow of water, which enters the throughflow regulator 3 through the area of the upstream sieve 2 above rising sloping surface 9 , towards the control gap 10 .
  • This way even in the case of a sectional clogging of the upstream sieve 2 in the central region, for example by contaminants in the inflowing water or by calcium deposit, sufficient water flow from the exterior region is ensured into the control gap 10 and subsequently into jet regulator 4 .
  • the bars or protrusions 12 positioned between the grooves 11 and limiting them end in proximity to the interior side of the upstream sieve 2 . This way, they can serve as support elements for the upstream sieve 2 , in order to improve the stability of the insert unit 1 and to prevent an undesired deformation of the upstream sieve 2 into the interior space 6 , for example by excessive pressure of the inflowing water or by the handling during the mounting process of the insert unit 1 .
