Description

Die Erfindung betrifft ein Auslaufmundstück für Sanitärarma­turen mit den im Oberbegriff des Anspruchs 1 angegebenen Merkmalen.
Derartige bekannte Auslaufmundstücke werden sowohl mit einer Belüftungseinrichtgung zum Anreichern des austretenden Was­serstrahls mit Luftblasen als auch ohne Belüftungseinrich­tungen bei Sanitärarmaturen, z.B. bei Waschtisch-, Küchen- ­und Wannenarmaturen, eingesetzt, wobei insbesondere durch die quer im Bereich der Austrittsöffnung angeordneten Siebe ein homogener, spritzfreier und weicher Wasserstrahl erzeugt wird (DE-OS 30 00 799 / DE-OS 14 59 518).
Die Gebrauchsdauer der Auslaufmundstücke wird meist von im Wasser mitgeführten Partikeln und den Ausscheidungen aus dem Wasser, insbesondere Kalkausscheidungen, bestimmt, die die Durchtrittsöffnungen verschließen. Wie mit Versuchen bestä­tigt wurde, haben in der Regel die im Wasser mitgeführten Partikeln nur einen geringen Einfluß auf die Gebrauchsdauer. Dagegen verursachen die Kalkausscheidungen aus dem Wasser, die sich als Ablagerungen im Sieb absetzen und somit die Siebmaschen verschließen, eine wesentliche Verringerung der Gebrauchsdauer. Bei einem Versorgungsnetz mit einem Wasser von 18 bis 22° dH traten bei einem handelsüblichen Auslauf­mundstück bei einer üblichen Gebrauchshäufigkeit bereits nach weniger als einem Vierteljahr deutliche Beeinträchti­gungen des Strahlbildes des aus dem Mundstück austretenden Wassers auf.The invention relates to a spout for sanitary fittings with the features specified in the preamble of claim 1.
Known outlet mouthpieces of this type are used both with a ventilation device for enriching the emerging water jet with air bubbles and without ventilation devices in sanitary fittings, for example in washbasin, kitchen and bath fittings, in particular through the sieves arranged transversely in the area of the outlet opening, a homogeneous, splash-free and soft water jet is generated (DE-OS 30 00 799 / DE-OS 14 59 518).
The service life of the outlet mouthpieces is usually determined by particles carried in the water and the excretions from the water, in particular lime deposits, which close the through openings. As has been confirmed with tests, those carried in the water usually have Particles only have a minor influence on the service life. In contrast, the calcium deposits from the water, which settle as deposits in the sieve and thus close the sieve mesh, cause a significant reduction in the service life. In the case of a supply network with a water of 18 to 22 ° dH, with a commercial outlet mouthpiece with a normal frequency of use, the jet pattern of the water emerging from the mouthpiece was clearly impaired after less than a quarter of a year.

Der Erfindung liegt die Aufgabe zugrunde, ein Auslaufmund­stück nach dem Oberbegriff des Anspruchs 1 zu schaffen, das gegen Kalkausscheidungen aus dem Wasser relativ unempfind­lich ist.The invention has for its object to provide an outlet mouthpiece according to the preamble of claim 1, which is relatively insensitive to lime deposits from the water.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß das stromabwärts angeordnete Sieb eine möglichst große Maschen­weite aufweist, wobei die Maschenweite so groß gewählt wer­den kann, daß noch ein den Querschnitt der Wasseraustritts­öffnung bedeckender Wassertropfen nach dem Absperren des Wasserzuflusses unter dem Sieb gehalten wird.
In der DE-OS 30 00 799 ist zwar am Rande bereits eine günstige Wirkung eines abflußseitigen Siebes mit gröberer Maschenweite erwähnt, wobei allerdings lediglich eine Ver­doppelung der Maschenweite zu den vorgeschalteten Feinsieben vorgeschlagen wird. Handelsübliche Feinsiebe haben etwa eine lichte Maschenweite von 0,5 mm. Die überragende Bedeutung einer möglichst großen Maschenweite im Hinblick auf das Ver­kalkungsverhalten wird jedoch offensichtlich nicht erkannt.This object is achieved in that the downstream sieve has the largest possible mesh size, the mesh size can be chosen so large that a water droplet covering the cross section of the water outlet opening is kept under the sieve after the water inlet has been shut off.
DE-OS 30 00 799 already mentions a favorable effect of a drain-side sieve with a coarser mesh size, although only a doubling of the mesh size to the upstream fine sieves is proposed. Commercially available fine sieves have a mesh size of about 0.5 mm. The outstanding importance of the largest possible mesh size with regard to the calcification behavior is obviously not recognized.

Mit der erfindungsgemäßen Ausbildung wird in überraschender Weise erreicht, daß die Kalkausscheidungen des Wassers im wesentlichen völlig unschädlich für die Funktionstüchtigkeit des Auslaufmundstückes erfolgen. Wahrscheinlich wird dies dadurch erreicht, daß bei in üblichen Benutzungszeiträumen nur der im unteren Sieb hängende Wassertropfen an der Luft eintrocknet und die Kalkausscheidungen unschädlich an den groben Maschen des unteren Siebes abgelagert werden. Zusätz­lich dürfte aber auch die Haftung der Kalkablagerungen an dem grobmaschigen Sieb reduziert sein, da in einem Versuch mit einem handelsüblichen Auslaufmundstück mit unveränderten Sieben und einem parallel betriebenen Auslaufmundstück mit erfindungsgemäß veränderten Sieben festgestellt wurde, daß bei dem erfindungsgemäßen Sieb kaum Kalkablagerungen fest­gestellt wurden, wenn das herkömmliche Sieb bereits nahezu vollkommen mit Kalkablagerungen verschlossen war.With the design according to the invention it is surprisingly achieved that the lime deposits of the water are essentially completely harmless to the functionality of the outlet mouthpiece. This is probably achieved by the fact that, in normal periods of use, only the water droplet hanging in the lower sieve dries in the air and the lime deposits are deposited harmlessly on the coarse meshes of the lower sieve. In addition, the adhesion of the limescale deposits to the coarse-mesh sieve should also be reduced, since in an experiment with a commercially available outlet mouthpiece with unchanged sieves and a parallel outlet nozzle with sieves according to the invention, it was found that hardly any limescale deposits were found in the sieve according to the invention if that conventional sieve was almost completely closed with limescale.

In weiterer Ausgestaltung der Erfindung kann vorteilhaft das untere Sieb aus einem Geflecht gebildet werden, das eine lichte Maschenweite von etwa 1,2 mm bis 5 mm hat. Zweckmäßig können auch die einzelnen Siebe stufenweise in Ausströmrichtung in der Maschenweite vergrößert werden.In a further embodiment of the invention, the lower sieve can advantageously be formed from a braid that has a clear mesh size of approximately 1.2 mm to 5 mm. The individual screens can also be expediently enlarged in the mesh size in the outflow direction.

Bei einem Auslaufmundstück mit einer Belüftungseinrichtung kann vorteilhaft das untere Sieb aus einem Drahtgeflecht ge­bildet werden, das eine lichte Maschenweite von etwa 1,5 mm hat, während die stromaufwärts angeordneten Siebe aus Draht­geflecht etwa eine lichte Maschenweite von 0,5 mm haben. Schließlich können vorteilhaft die einzelnen Siebe aus ver­kalkungsunempfindlichem Material wie Kunststoff hergestellt werden.In the case of an outlet mouthpiece with a ventilation device, the lower sieve can advantageously be formed from a wire mesh which has a clear mesh size of approximately 1.5 mm, while the upstream wire mesh sieves have a clear mesh size of 0.5 mm. Finally, the individual sieves can advantageously be made of calcification-insensitive material such as plastic.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung teilweise im Längsschnitt als Auslaufmundstück mit Belüf­tungseinrichtung dargestellt und wird im folgenden näher be­schrieben.An embodiment of the invention is shown in the drawing, partly in longitudinal section, as an outlet mouthpiece with a ventilation device and is described in more detail below.

Das dargestellte Auslaufmundstück entspricht mit seinem Ge­häuse 1 und einer Belüftungseinrichtung 2 einem handelsüb­lichen Wasserstrahlbelüfter.
Das Auslaufmundstück wird hierbei mit seinem Gehäuse 1 mit Hilfe eines Gewindes 11 und einer Dichtung 12 an das Aus­laufrohr einer Wasserzapfarmatur angeschlossen. Beim Wasser­zapfvorgang tritt das ausströmende Wasser zunächst durch ein Fangsieb 3, mit dem grobe Partikeln aus dem Wasser abgeson­dert werden. Hiernach wird das zuströmende Wasser in Strahl­düsen 21 in Einzelstrahlen zerlegt, die eine hohe Geschwin­digkeit aufweisen, wodurch ein Unterdruck entsteht, so daß Luft durch Luftansaugkanäle 22 den Wasserstrahlen zugeführt wird und sich mit Ihnen vermischt. Stromabwärts hinter der Belüftungseinrichtung 2 sind Siebe 5,6 mit Abstand zueinan­der angeordnet. Die Siebe 5 weisen dabei ein quadratisches Drahtgeflecht auf, das jeweils eine Maschenweite von 0,5 mm hat. Das stromabwärts gelegene Sieb 6 weist ebenfalls ein quadratisches Drahtgeflecht auf, dessen lichte Maschenweite jedoch 1,5 mm beträgt. Das in der Belüftungseinrichtung 2 erzeugte Wasserluftgemisch wird durch die Siebe 5 homogeni­siert und verläßt das Auslaufmundstück durch das Sieb 6. Bei einem Absperren des Wasserzuflusses bleibt das restliche Wasser zwischen den Sieben 5 bis 6 haften und bildet unter­halb des Siebes 6 einen Tropfen, der den Gesamtquerschnitt des Auslaufmundstücks bedeckt. In den Zeiträumen, wo kein Wasser gezapft wird, trocknet der unterhalb des Siebes 6 hängende Wassertropfen ein und lagert die Kalkausscheidungen an dem unteren Sieb 6 ab, wodurch wesentlich verhindert wird, daß auch an den engeren Sieben 5 Kalkausscheidungen erfolgen.
Durch Versuche wurde ermittelt, daß die Verkalkungsneigung wesentlich verringert wird bzw. mindestens eine Verdreifa­chung der Lebensdauer gegenüber herkömmlichen Wasserauslauf­mundstücken erreicht werden kann.The outlet mouthpiece shown corresponds with its housing 1 and a ventilation device 2 to a commercially available water jet aerator.
The outlet mouthpiece is connected with its housing 1 with the aid of a thread 11 and a seal 12 to the outlet pipe of a water tap fitting. In the water tapping process, the outflowing water first passes through a strainer 3 with which coarse particles are separated from the water. Thereafter, the inflowing water is broken down into jet nozzles 21 into individual jets which have a high speed, which creates a negative pressure so that air is supplied to the water jets through air intake channels 22 and mixes with them. Sieves 5, 6 are arranged at a distance from one another downstream of the ventilation device 2. The screens 5 have a square wire mesh, each of which has a mesh size of 0.5 mm. The downstream sieve 6 also has a square wire mesh, the clear mesh size of which is 1.5 mm. The water-air mixture generated in the ventilation device 2 is homogenized by the sieves 5 and leaves the outlet mouthpiece through the sieve 6. When the water inflow is shut off, the remaining water remains adhering between the sieves 5 to 6 and forms a drop below the sieve 6, which has the total cross section of the outlet mouthpiece covered. In the periods when no water is tapped, the water drop hanging below the sieve 6 dries and deposits the lime deposits on the lower sieve 6, which substantially prevents 5 lime deposits from occurring on the narrower sieves.
Experiments have shown that the tendency to calcification is significantly reduced or at least triples in life compared to conventional water outlet mouthpieces can be achieved.
