Aus der
Strahlregler mit einem als Diffusor ausgestalteten Strahlzerleger sind jedoch vor allem in einem bestimmten Anwendungsbereich, insbesondere bei geringen Wasserdrücken, vorteilhaft einsetzbar.Jet regulators with a jet splitter designed as a diffuser can, however, be used advantageously above all in a certain area of application, in particular with low water pressures.
Aus der
Es besteht daher die Aufgabe, eine sanitäre Einsetzeinheit der eingangs erwähnten Art zu schaffen, die sich durch einen breiteren Einsatzbereich auszeichnet oder in anderen Anwendungsbereichen vorteilhaft eingesetzt werden kann, wobei sich die erfindungsgemäße Einsetzeinheit auch dadurch auszeichnen soll, dass in ihr ein möglichst homogener und nichtspritzender Wasserstrahl geformt werden kann.The object is therefore to create a sanitary insert unit of the type mentioned at the beginning, which is characterized by a broader range of application or can be used advantageously in other areas of application, the insert unit according to the invention also being characterized in that it is as homogeneous and non-spattering as possible Water jet can be shaped.
Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der sanitären Einsetzeinheit der eingangs erwähnten Art insbesondere darin, dass in dem von der Projektion des zumindest einen Durchflusskanals umgrenzten Zentralbereich des Strahlzerlegers zumindest ein Durchflussloch vorgesehen ist, und dass die Durchflusslöcher des Strahlzerlegers einen Einström-Lochabschnitt und einen Ausström-Lochabschnitt haben.The inventive solution to this problem consists in the sanitary insert unit of the type mentioned in particular that in the central area of the jet splitter delimited by the projection of the at least one flow channel at least one flow hole is provided, and that the flow holes of the jet splitter have an inflow hole section and an outflow -Have hole section.
Die erfindungsgemäße Einsetzeinheit ist am Wasserauslauf einer sanitären Auslaufarmatur montierbar. Die Einsetzeinheit weist eine zuströmseitige Durchflussmengenregler-Einheit auf, auf deren Abströmseite ein Strahlregler vorgesehen ist. Während die Durchflussmengenregler-Einheit die pro Zeiteinheit durchströmende Wassermenge druckunabhängig auf einen festgelegten Maximalwert einzuregeln hat, soll der Strahlregler der erfindungsgemäßen Einsetzeinheit das dort austretende Wasser zu einem homogenen, nicht-spritzenden und gegebenenfalls auch perlend-weichen Wasserstrahl formen.The insert 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 the downstream side of which is provided with a jet regulator. While the flow rate regulator unit has to regulate the amount of water flowing through per unit of time to a specified maximum value independent of pressure, the jet regulator of the insert unit according to the invention should shape the water exiting there into a homogeneous, non-splashing and possibly also pearly-soft water jet.
Die Durchflussmengenregler-Einheit der erfindungsgemäßen Einsetzeinheit weist zumindest einen ringförmigen Durchflusskanal auf, in dem ein ringförmiger Drosselkörper aus elastischem Material vorgesehen ist. Der in dem zumindest einen Durchflusskanal befindliche Drosselkörper begrenzt zwischen sich und einer benachbarten, eine Regelprofilierung aufweisenden Kanalwandung einen Steuerspalt, dessen Durchtrittsquerschnitt durch den sich unter der beim Durchströmen bildenden Druckdifferenz verformenden Drosselkörper veränderbar ist.

In dem von der Projektion des zumindest einen Durchflusskanals umgrenzten Zentralbereich des Strahlzerlegers ist zumindest ein Durchflussloch vorgesehen. Da im Zentralbereich des Strahlzerlegers zumindest ein Durchflussloch vorgesehen ist, wird die Bildung eines im Strahlquerschnitt homogenen und nicht-spritzenden Auslaufstrahls im Strahlrelger der erfindungsgemäßen Einsetzeinheit begünstigt. Dabei weisen die Durchflusslöcher des Strahlzerlegers einen einströmenden Loch-Abschnitt und einen ausströmenden Loch-Abschnitt auf. Die erfindungsgemäße Einsetzeinheit zeichnet sich durch eine auch über große und insbesondere höhere Druckbereiche vorteilhafte Funktionsweise aus.The flow rate regulator unit of the insert unit according to the invention has at least one annular flow channel in which an annular throttle body made of elastic material is provided.

At least one throughflow hole is provided in the central region of the jet splitter that is delimited by the projection of the at least one throughflow channel. Since at least one through-flow hole is provided in the central area of the jet splitter, the formation of an outlet jet which is homogeneous in terms of jet cross-section and which does not spray is promoted in the jet regulator of the insert unit according to the invention. The throughflow holes of the jet splitter have an inflowing hole section and an outflowing hole section. The insertion unit according to the invention is distinguished by a mode of operation that is advantageous even over large and, in particular, higher pressure ranges.

Um die in Verlängerung zumindest eines der Durchflusskanäle vorgesehene lochfreie Ringzone im Strahlzerleger möglichst schmal halten zu können, und um in dem außerhalb der Durchflusskanäle liegenden Teilbereich des Strahlzerlegers möglichst viele Durchflusslöcher platzieren zu können, ist es vorteilhaft, wenn die Durchflusskanäle zweier benachbarter Durchflussmengenregler durch eine Ringwandung voneinander getrennt sind, und wenn die Regelprofilierung dieser Durchflusskanäle auf der Innenseite und der Außenseite dieser Ringwandung vorgesehen sind.In order to be able to keep the hole-free ring zone in the jet splitter provided as an extension of at least one of the flow channels as narrow as possible, and in order to be able to place as many flow holes as possible in the partial area of the jet splitter located outside the flow channels, it is advantageous if the flow channels of two adjacent flow regulators are through an annular wall are separated from each other, and if the regular profiling of these flow channels are provided on the inside and the outside of this ring wall.
Die Bildung eines homogenen Auslaufstrahls im Strahlregler der erfindungsgemäßen Einsetzeinheit wird begünstigt, wenn die außerhalb der Projektion des zumindest einen Durchflusskanals angeordneten Durchflusslöcher des Strahlzerlegers auf wenigstens einer Kreisbahn und vorzugsweise auf mindestens zwei Kreisbahnen angeordnet sind.The formation of a homogeneous outlet jet in the jet regulator of the insert unit according to the invention is promoted if the flow holes of the jet splitter arranged outside the projection of the at least one flow channel are arranged on at least one circular path and preferably on at least two circular paths.
Dabei sieht eine bevorzugte Ausführung gemäß der Erfindung vor, dass die die Durchflusslöcher aufweisenden Kreisbahnen konzentrisch zueinander und/oder zur Projektion des zumindest einen Durchflusskanals angeordnet sind.A preferred embodiment according to the invention provides that the circular paths having the throughflow holes are arranged concentrically to one another and / or to the projection of the at least one throughflow channel.

Die Einsetzeinheit 1 weist eine Durchflussmengenregler-Einheit 4 auf, welche die pro Zeiteinheit durchströmende Wassermenge druckunabhängig auf einen festgelegten Maximalwert einregelt. In zumindest einem, im wesentlichen ringförmigen Durchflusskanal 5, 6 der Durchflussmengenregler-Einheit 4 ist ein ringförmiger Drosselkörper 7, 8 aus elastischem Material vorgesehen, welcher zwischen sich und einer benachbarten Kanalwandung, die eine Regelprofilierung 24 aus in Durchströmrichtung orientierten Ein- und Ausformungen 11, 12 trägt, einen Steuerspalt 13 begrenzt, dessen Durchtrittsquerschnitt durch den sich unter der beim Durchströmen bildenden Druckdifferenz verformenden Drosselkörper 7, 8 verändert. Je nach Wasserdruck formt der Drosselkörper in den jeweils einen Durchflussmengenregler bildenden Durchflusskanälen 5, 6 sich mehr oder weniger stark in die Regelprofilierung 24 und der lichte Steuerspalt 13 verändert sich entsprechend.The
Die Durchflussmengenregler-Einheit 4 weist hier zwei konzentrische Durchflusskanäle 5, 6 auf, in denen jeweils ein elastischer Drosselkörper 7, 8 eingelegt ist. Dabei ist in dem, einen kleineren Durchmesser aufweisenden innenliegenden Durchflusskanal 5 ein Drosselkörper 7 vorgesehen, der im Vergleich zu dem im außenliegenden, einen größeren Durchmesser aufweisenden Durchflusskanal 6 befindlichen Drosselkörper 8 einen kleineren Materialquerschnitt, insbesondere eine kleinere Schnurstärke, hat, und deshalb leichter auch auf geringe Wasserdrücke und Wasserdruckänderungen reagiert.The flow rate regulator unit 4 here has two
Auf der Abströmseite der Durchflussmengenregler-Einheit 4 ist ein Strahlregler 9 angeordnet, der das anströmende Wasser zu einem homogenen, nicht-spritzenden und gegebenenfalls perlend-weichen Wasserstrahl formen soll. Dieser Strahlregler 9 hat einen als Lochplatte ausgebildeten Strahlzerleger 10 mit einer Mehrzahl von Durchflusslöchern 29, welcher Strahlzerleger 10 das von der Durchflussmengenregler-Einheit 4 kommende Wasser im Einsetzgehäuse 2 zunächst in eine Vielzahl von Einzelstrahlen aufteilt.On the outflow side of the flow rate regulator unit 4, a jet regulator 9 is arranged, which is intended to shape the inflowing water into a homogeneous, non-splashing and possibly pearly-soft water jet. This jet regulator 9 has a
Damit das von der Durchflussmengenregler-Einheit 4 noch mit einer hohen Geschwindigkeit anströmende Wasser nicht direkt und ungebremst durch die Durchflusslöcher 29 im Strahlzerleger 10 fließt, ist die Projektion zumindest eines der Durchflusskanäle 5, 6 in einer lochfreien Ringzone 27 des Strahlzerlegers 10 angeordnet, das heißt in der axialen Verlängerung zumindest eines der Durchflusskanäle 5, 6 ist eine lochfreie Ringzone 27 des Strahlzerlegers 10 vorgesehen.So that the water flowing from the flow rate regulator unit 4 does not flow directly and unchecked through the
In den Durchflusslöchern 29 der Lochplatte tritt das durchfließende Wasser mit einer erhöhten Geschwindigkeit aus, die auf der Abströmseite der Lochplatte einen Unterdruck bewirkt, welcher Unterdruck Umgebungsluft in das Gehäuseinnere des Einsetzgehäuses 2 saugt. Dazu sind in der Gehäusewandung des Einsetzgehäuses 2 in der direkt unterhalb des als Lochplatte ausgebildeten Strahlzerlegers 10 gelegenen Ringzone Belüftungsöffnungen 28 vorgesehen. Die vom Strahlzerleger 10 kommenden Einzelstrahlen werden im Gehäuseinneren des Einsetzgehäuses 2 - in der im Gehäuseinneren unterhalb dem Strahlzerleger 10 gelegenen Mischzone - mit der Umgebungsluft durchmischt. Um diese Durchmischung noch zusätzlich zu begünstigen und um das Wasser weiter abzubremsen, können im Einsetzgehäuse 2 Einsetzteile 14, 15 eingesetzt sein, die innerhalb einer außenliegenden Ringwand 16 eine Gitter- oder Netzstruktur aus einander an Kreuzungsknoten sich kreuzenden Stegen 17, 18 haben.In the through-
Dabei kreuzen sich hier konzentrische Stege 17 mit radialen Stegen 18 und bilden eine Netzstruktur aus, an der das Wasser noch weiter aufgeteilt und vermischt wird. An die Einsetzteile 14, 15 schließt sich abströmseitig ein Strömungsgleichrichter 19 mit Auslauföffnungen 20 an, welche Auslauföffnungen 20 eine vergleichsweise hohe Längserstreckung im Vergleich zum Lochquerschnitt haben. In den Auslauföffnungen 20 dieses Strömungsgleichrichters 19 wird das dort austretende Wasser zu einem homogenen Auslaufstrahl geformt. Dabei bildet der Strömungsgleichrichter 19 die auslaufseitige Stirnfläche der Einsetzeinheit 1. Auf der Abströmseite des Strömungsgleichrichters 19 ist eine Gehäuseeinschnürung 21 vorgesehen, die ein unerwünschtes Spritzen seitlich des austretenden Wasserstrahls verhindert.Here
Damit das Wasser nicht als instabiler Ringstrahl austritt und damit das austretende Wasser auch einen homogenen Strahlquerschnitt hat, ist in den von der Projektion des zumindest einen Durchflusskanals 5, 6 umgrenzten Zentralbereich 22 des Strahlzerlegers zumindest ein Durchflussloch 29 und - wie hier - vorzugsweise mehrere Durchflusslöcher 29 vorgesehen.So that the water does not emerge as an unstable ring jet and thus the emerging water also has a homogeneous jet cross-section, there is at least one
Damit trotz der lochfreien Ringzone 12 noch eine ausreichende Anzahl von Durchflusslöchern 29 in der als Strahlzerleger 10 dienenden Lochplatte platziert werden können, sind die Durchflusskanäle 5, 6 durch eine Ringwandung 23 voneinander getrennt, wobei die Regelprofilierungen 24 der konzentrisch zueinander angeordneten Durchflusskanäle 5, 6 auf der Innenseite und der Außenseite dieser Ringwandung 23 vorgesehen sind. Auf diese Weise lässt sich die lochfreie Ringzone 27 vergleichsweise schmal ausgestalten.So that a sufficient number of throughflow holes 29 can still be placed in the perforated plate serving as
