Description

Die Erfindung bezieht sich auf einen Strahlregler für den Wasserstrahlaustritt einer Wasserauslaufarmatur, insbesondere für Trinkwasser, mit einem an die Wasserauslaufarmatur ansetzbaren Mundstück mit Dichtung und der Wasserstrahlformung dienenden Innenteil.The invention relates to a jet regulator for the water jet outlet a water outlet fitting, especially for drinking water, with one to the Water outlet fitting attachable mouthpiece with seal and water jet shaping serving inner part.

Strahlregler der vorbezeichneteten Gattung sind auch unter der Bezeichnung "Perlator" bekannt. Die bekannten Strahlregler versprudeln das der Wasserauslaufarmatur entströmende Wasser mit Luft, so daß der Wasserstrahl angenehm weich ist und kaum spritzt.Flow regulators of the aforementioned type are also under the name "Perlator" known. The well-known jet regulators bubble that of the water outlet fitting flowing water with air, making the water jet pleasant is soft and hardly splashes.

Die bekannten Strahlregler umfassen ein Mundstück mit Dichtung, welches an den Austritt einer Wasserauslaufarmatur ansetzbar ist. Das Mundstück wird mit dem Austritt der Wasserauslaufarmatur verschraubt. Dazu sind die zu verbindenden Bauteile mit entsprechenden Gewinden ausgerüstet. Zur Abdichtung zwischen Mundstück und Wasserauslaufarmatur ist in dem Mundstück eine Dichtung vorhanden. The known jet regulators include a mouthpiece with a seal, which the outlet of a water outlet fitting is attachable. The mouthpiece is screwed to the outlet of the water outlet fitting. They are too connecting components equipped with appropriate threads. For sealing between the mouthpiece and the water outlet fitting is in the mouthpiece a seal is present.

Der Wasserstrahlformung bzw. der Versprudelung mit Luft dient ein in das Mundstück eingebautes Innenteil. Bekannte Innenteile weisen siebkorbartige Ausgestaltungen auf und sind mit Ansaugkanälen für Luft versehen.The water jet forming or the bubbling with air serves in the Mouthpiece built-in inner part. Known inner parts have strainer-like ones Designs on and are provided with intake channels for air.

Die bisher bekannten Strahlregler neigen zu Verkalkungen, denn im gezapften Trinkwasser ist mehr oder weniger viel Kalk gelöst. Wird kein Trinkwasser gezapft, ist also die Wasserauslaufarmatur geschlossen, verbleibt im Strahlregler eine geringe Menge nicht abgetropften Trinkwassers. Wird längere Zeit kein weiteres Wasser gezapft, verdunstet ein Teil der Wasserrestmenge, und in der Wasserrestmenge nimmt dabei die Konzentration der gelösten Komponenten, insbesondere der Kalkkomponente zu. Dies kann letztlich dazu führen, daß sich Kalk im Inneren des Strahlreglers an unerwünschten Stellen absetzt, mit der Folge, daß der Strahlregler, insbesondere sein Innenteil, die zugedachte Funktion verliert.The previously known jet regulators tend to calcify, because in the tap Drinking water is more or less dissolved in lime. Will not be drinking water tapped, i.e. the water outlet fitting is closed, remains in the jet regulator a small amount of non-drained drinking water. Will be a long time no more water is drawn off, part of the remaining water evaporates, and the concentration of the dissolved components in the residual water quantity especially the lime component. This can ultimately lead to that there is lime in the interior of the jet regulator at undesirable locations sets, with the result that the aerator, especially its inner part, the intended function loses.

Der Erfindung liegt die Aufgabe zugrunde, einen Strahlregler so auszubilden, daß seiner Verkalkung entgegengewirkt wird.The invention has for its object to design a jet regulator so that its calcification is counteracted.

Diese Aufgabe ist durch die Merkmale des Schutzanspruchs 1 gelöst. Vorteilhafte Weiterbildungen der Erfindung und Ausgestaltungen des erfindungsgemäßen Strahlreglers ergeben sich aus den Merkmalen der Unteransprüche 2 bis 6.This object is achieved by the features of claim 1. advantageous Developments of the invention and refinements of the invention Jet regulator result from the features of subclaims 2 until 6.

Dadurch, daß bei dem Strahlregler in erfindungsgemäßer Weise in sein Mundstück eine Vorrichtung zur Keimbildung mindestens einer im Wasser gelösten Komponente, insbesondere eine Vorrichtung zur Kalkkristallkeimbildung, angeordnet ist, bilden sich im vorhandenen Restwasser bei Zunahme der Konzentration der gelösten Kalkkomponente Kalkkristalle. Die Bildung der Kalkkristallkeime führt zur Abnahme der Konzentration der gelösten Komponente im Restwasser, daß der Strahlregler noch enthält, so daß die Neigung zur Verkalkung des Strahlreglers mit Vorteil absinkt. Sobald an der Wasserauslaufarmatur erneut gezapft wird, werden die gebildeten Kalkkristalle ausgeschwemmt. Characterized in that be in the jet regulator in the inventive manner Mouthpiece a device for nucleation of at least one in the water dissolved component, in particular a device for lime crystal nucleation, is arranged, form in the existing residual water with an increase the concentration of the dissolved lime component lime crystals. The formation of the Lime crystal nuclei lead to a decrease in the concentration of the dissolved component in the residual water that the jet regulator still contains, so that the inclination for calcification of the jet regulator advantageously decreases. As soon as at the water outlet fitting is tapped again, the lime crystals formed are washed out.

Die Kalkkristallkeimbildung führt somit zu einer wesentlichen Verlangsamung, wenn nicht sogar zur Verhinderung der Kalkabsetzung im Strahlregler.The lime crystal nucleation thus leads to a significant slowdown, if not to prevent limescale build-up in the aerator.

Die Vorrichtung zur Kalkkristallkeimbildung ist mit Vorteil als wasserdurchlässiges Behältnis ausgebildet. Dieses Behältnis kann somit Wasser aufnehmen und wieder abgeben. Das Behältnis enthält ein schwach sauer konditioniertes lonenaustauschmaterial, dessen Carboxylatgruppe mit CA2+ - Ionen beladen ist.The device for lime crystal nucleation is advantageously designed as a water-permeable container. This container can thus absorb water and release it again. The container contains a weakly acid conditioned ion exchange material, the carboxylate group of which is loaded with CA 2+ ions.

Ein solches lonenaustauschmaterial ist in der Lage, in dem in das Behältnis eingedrungenen Restwasser Kalkkristallkeime zu bilden, die dann, wenn das damit belastete Wasser aus dem Behältnis wieder abtropft, an die ebenfalls noch im Strahlregler vorhandene Restwassermenge abgegeben werden. Dort führen die gebildeten Kristallkeime zur Ausfällung weiterer Kalkkristalle aus dem Restwasser, womit die Neigung, daß aus dem Restwasser Kalk an Fremdoberflächen im Strahlregler abgesetzt wird, erheblich herabgesetzt wird.Such an ion exchange material is capable of being in the container penetrated residual water to form limestone nuclei, which if the thus contaminated water drips out of the container, to which also Any residual water still present in the jet regulator can be dispensed. There the crystal nuclei formed lead to the precipitation of further lime crystals the residual water, with the tendency for limescale to form from the residual water Foreign surfaces in the aerator are significantly reduced becomes.

Sobald frisches Wasser gezapft wird, werden die gebildeten Kalkkristalle sowie das damit befrachtete Restwasser ausgeschwemmt.As soon as fresh water is tapped, the limestone crystals formed as well the residual water loaded with it washes out.

Um die Wasserdurchlässigkeit des Behältnisses zu steigern, sind vorbestimmte Bereiche der Wandung des Behältnisses mit Durchbrechungen versehen, beispielsweise siebartig ausgebildet, derart, daß zwar Wasser durchgelassen wird, jedoch das lonenaustauschmaterial im Behältnis verbleibt.In order to increase the water permeability of the container, there are predetermined ones Provide areas of the wall of the container with openings, for example, sieve-shaped, such that water is admitted However, the ion exchange material remains in the container.

Mit besonderem Vorteil ist das Behältnis als in das Mundstück einlegbarer Hohlring ausgebildet. Der Hohlring weist vorzugsweise eine etwas rechteckige Querschnittsform auf. Der innere Hohlraum des Hohlrings enthält das als Granulat vorliegende lonenaustauschmaterial, bildete also eine Aufnahmekammer. In die Aufnahmekammer kann Wasser von außen eindringen und auch wieder nach außen abgegeben werden, da die Wandung des Behältnisses siebartig bzw. stark porös ausgebildet ist. Nach dem Einsetzen des Innenteil in das Mundstück kann das als Hohlring vorliegende Behältnis auf das Innenteil gesetzt werden und schließlich wird auf dem Hohlring wiederum die Dichtung in Form eines Dichtringes, beispielsweise aus Gummi, angeordnet. Bei Verschrauben mit der Armatur sind alle Bauteile des Strahlreglers miteinander verspannt.The container is particularly advantageous as it can be inserted into the mouthpiece Hollow ring formed. The hollow ring preferably has a somewhat rectangular shape Cross-sectional shape. The inner cavity of the hollow ring contains that ion exchange material present as granules, thus forming a receiving chamber. Water can penetrate from the outside into the receiving chamber also be given back to the outside because the wall of the container sieve-like or strongly porous. After inserting the inner part in the mouthpiece, the container present as a hollow ring on the Be placed inside and finally the turn on the hollow ring Seal in the form of a sealing ring, for example made of rubber, arranged. When screwing to the valve, all components of the jet regulator are together braced.

Der Werkstoff für das Behältnis, bzw. das in Form eines Hohlringes vorliegende Behältnis, ist vorzugsweise Kunststoff. Dieser Werkstoff erlaubt die Fertigung im Spritzgußverfahren bzw. in einem Extrusionsverfahren.The material for the container, or that in the form of a hollow ring Container, is preferably plastic. This material allows the Manufacturing by injection molding or in an extrusion process.

Bei einem Extrusionsverfahren kann ein Hohlprofil mit den Abmessungen des Querschnitts des Hohlringes endlos gefertigt werden. Dieses Hohlprofil läßt sich mit dem lonenaustauschmaterial in Form eines Granulats füllen, auf Länge schneiden und dann zu einem Ring biegen und an der Nahtstelle stoßen und verbinden.In an extrusion process, a hollow profile with the dimensions of the Cross section of the hollow ring are made endless. This hollow profile leaves fill up with the ion exchange material in the form of granules Cut length and then bend into a ring and butt at the seam and connect.

Es ist jedoch auch möglich, die an der Innenwand des Mundstücks zu liegen kommende Außenseite des Hohlringes als Verschlußstreifen auszubilden, der nach der Einfüllung des lonenaustauschmaterials in den Hohlring eingesetzt und z. B. verklebt wird.However, it is also possible to lie on the inner wall of the mouthpiece to develop the coming outside of the hollow ring as a sealing strip after filling the ion exchange material into the hollow ring and Z. B. is glued.

Jede andere Fertigungsmethode zur Herstellung eines Hohlrings ist natürlich möglich. Wichtig ist lediglich, daß der Hohlring das lonenaustauschmaterial enthält, welches aufgrund der Abmessungen des Hohlrings, ausreichende, und somit für die Bildung von Kalkkristallkeimen vorteilhafte Oberflächen bietet und außerdem Wasser leicht eindringen, aber auch den Hohlring leicht wieder verlassen kann.Any other method of manufacturing a hollow ring is natural possible. It is only important that the hollow ring contains the ion exchange material contains, which, due to the dimensions of the hollow ring, sufficient and thus surfaces advantageous for the formation of lime crystal nuclei offers and also water easily penetrate, but also the hollow ring easily can leave again.
