Definitions

  • the invention relates to a sanitary insert unit with an insert housing which can be mounted on or in a water outlet of a sanitary outlet fitting and in whose housing interior there is a liquid path which, when in use, guides water flowing through the housing interior, with a jet splitter having a plurality of splitter openings are provided, which divide the water flowing through into a plurality of individual jets, and with at least one lattice or network structure following the jet splitter in the liquid path, with at least one by-pass channel being provided which bypasses the liquid path at least in sections and which at least has a tapering clear channel cross-section in a partial section, wherein the at least one bypass channel tapers or narrows in the direction of its outflow-side channel opening and wherein the bypass channel passes through the jet splitter.
  • a sanitary insert unit of the type mentioned is already known, which can be mounted on the water outlet of a sanitary outlet fitting using a sleeve-shaped outlet mouthpiece in order to shape the water flowing through into a homogeneous outlet jet.
  • the previously known insert unit has an insert housing which can be inserted into the outlet mouthpiece and in the housing interior of which a liquid path is provided which, during use, guides water flowing through the housing interior.
  • a jet splitter with splitter openings, which are designed as inflow openings, is provided on the inflow side of the previously known insertion unit. In these inflow openings the water flowing through is divided into a plurality of individual jets, which are guided to inner and outer flow chambers.
  • the water outlet side of the DE 10 2004 044 158 B3 previously known insertion unit is closed by a base in which a plurality of continuous inner and outer water outlet nozzles are arranged along two concentric circles in a bottom view. These water outlet nozzles form a lattice structure that follows the jet splitter in the liquid path.
  • a central bypass channel bypassing the liquid path at least in sections is also provided, and a valve with a valve piston that can be displaced in the water flow direction is arranged in front of the inlet opening of the channel.
  • the valve disc of this valve has a water inlet opening leading to the cleaning jet channel, with the cleaning jet channel running in the hollow valve piston. If the dynamic pressure of the water on the valve disk increases, the entire cleaning jet channel is moved into the water outlet seal and the valve is opened so that, in addition to the cleaning jet, a soft jet made up of several individual jets emerges from the water outlet nozzles.
  • a cleaning jet is first generated, which is replaced by a soft jet formed from a number of individual jets as the dynamic pressure increases.
  • the cleaning jet cannot be amplified by an arbitrary increase in flow rate - instead, a soft jet is provided.
  • a sanitary insert unit is already known, which is formed from an inflow-side flow rate regulator and an outflow-side jet regulator.
  • the flow rate regulator of the previously known insert unit has a shell-shaped regulator housing with an outer peripheral edge area that extends radially outwards as a protruding annular flange is designed. With this outer edge area of its regulator housing designed as a flat annular flange, the flow rate regulator of the previously known insert unit rests on the inflow-side end peripheral edge area of the downstream-side adjacent jet regulator.
  • the shell interior of the regulator housing which is open towards the outflow side, is dimensioned such that a partial area of an attachment screen protruding beyond the front peripheral edge area of the jet regulator can also be accommodated therein.
  • the flow rate regulator of the previously known insert unit can thus also be used subsequently in an already existing installation situation in which a jet regulator and an upstream attachment sieve are already present and mounted at the outlet end of a sanitary outlet fitting.
  • a sanitary insert unit which has an inflow-side filter screen with at least one dirt outlet opening, which dirt outlet opening has an enlarged clear opening cross section compared to the screen openings of the filter screen.
  • the at least one dirt outlet opening opens into at least one by-pass or cleaning channel, with the dirt outlet opening being arranged in front of and the channel outlet of the at least one by-pass or cleaning channel being arranged in the direction of flow behind at least one liquid-carrying component of the previously known insert unit.
  • the dirt outlet opening has this Filter screen on compared to the screen openings of the filter screen enlarged clear opening cross section.

  • the at least one dirt outlet opening of the filter screen is arranged in the direction of flow in front of and the channel outlet of the by-pass or cleaning channel in the direction of flow behind at least one liquid-carrying component of at least one functional unit located in the previously known insert unit. Since the dirt particles that may endanger the functioning of this water-carrying component can be discharged via the by-pass or cleaning channel during the interruption of the water supply, low-maintenance and trouble-free functioning of the previously known insertion unit is ensured. During normal use, however, no accelerated jet of liquid is provided for cleaning purposes by this previously known sanitary insert unit either.
  • an outlet mouthpiece which can be mounted on the water outlet of a sanitary outlet fitting and whose flow cross section can be adjusted.
  • a cone made of an elastically resilient material is provided in the previously known outlet mouthpiece, which cone forms a conically widening annular gap between itself and an outlet opening adapted to the cone.
  • the overpressure prevailing in front of the annular outlet gap weighs on the small end face of the flexible cone and causes the cone to be deformed in the sense of a bulging of its outer surface. Since this overpressure depends on the pressure in the inflow line, the cone is deformed more with increasing inflow pressure. This increases the clear width of the Annular gap reduced and counteracted an increase in the amount of water flowing out.
  • a sanitary insert unit with an insert housing is already known, which can be mounted on the water outlet of a sanitary outlet fitting using an outlet mouthpiece (cf. publication on the Internet at www.neoperl.net/de/oem/products/aerators/productlines/perlator hcflowthru.html and U.S. DesPat D622,356).
