Abstract

A faucet aerator having a cylindrical housing with air openings therein and a lenticular screen arrangement in the housing downstream from the openings. The screen arrangement comprises two curved or dished screens arranged with their peripheral edges abutting and with their central portions spaced apart to form an air/water mixing chamber between them. The screens, in one embodiment, are integrally joined together along a portion of their peripheries. The aerator includes support means on the housing for supporting the screen arrangement by its peripheral edge on one side. A perforated member is mounted in the housing upstream from the air openings and a central spacer projects downstream to hold the screen arrangement against the support means.

Description

Die Erfindung betrifft einen Perlator für Wasserhahnmund­stücke, mit einem zylindrischen Gehäuse, in dem Gehäuse angeordneten Luftschlitzen sowie unterhalb der Luftschlitze in das Gehäuse eingesetzten Sieben, wobei der Perlator in ein zylindrisches Gehäuse einsteckbar und dieses am Wasser­hahnmundstück befestigbar ist.The invention relates to a aerator for faucet mouthpieces, with a cylindrical housing, air slots arranged in the housing and sieves inserted into the housing below the air slots, the aerator being insertable into a cylindrical housing and attachable to the faucet mouthpiece.

Perlatoren dienen dem Zweck, Wasser-Luft-Gemische aus den Mundstücken von Wasserhähnen austreten zu lassen. Dazu wird Luft seitlich in den Perlator eingezogen, die dann mit dem Wasserstrahl vermischt wird, um diesen ergiebiger werden zu lassen und um Fließgeräusche zu dämpfen. Unterhalb der Luft­schlitze befinden sich mehrere in Abstand voneinander ange­ordnete Siebe, die den Wasserstrahl teilen und es infolge­dessen hinter jedem Sieb zu einer innigen Durchmischung des aufgeteilten Wasserstrahles mit der Luft kommt. Die Siebe sind eben ausgebildet und weisen an ihrem Rand eine Ab­standsaufbördelung auf, so daß benachbarte Siebe im Bereich der betreffenden Aufbördelung aufeinander zu liegen kommen und hierdurch der Abstand benachbarter Siebe vorgegeben ist.The purpose of aerators is to let water-air mixtures emerge from the mouthpieces of taps. For this purpose, air is drawn into the side of the aerator, which is then mixed with the water jet to make it more productive and to dampen flow noises. Below the louvers are a number of spaced-apart screens that divide the water jet and, as a result, the split water jet is thoroughly mixed with the air behind each screen. The sieves are flat and have a flared spacing at their edge, so that adjacent sieves come to lie on top of one another in the region of the flare concerned and the spacing of adjacent sieves is thereby predetermined.

Die bekannten Perlatoren haben sich in der Praxis durch­aus bewährt. Nachteilig ist bei ihnen jedoch, daß die Her­stellung der Abstandsaufbördelung der einzelnen Siebe des Perlators kostenintensiv ist und außerdem die Außensiebe sich mit der Zeit verlegen.The known aerators have proven themselves in practice. It is disadvantageous for them, however, that the production of the flanging of the spacing of the individual sieves of the aerator is cost-intensive and, in addition, the outer sieves move over time.

Es ist Aufgabe vorliegender Erfindung, einen Perlator der genannten Art zu schaffen, der billiger als bekannte Perla­toren herzustellen ist, dabei jedoch nach wie vor gewähr­leistet ist, daß eine intensive Vermischung des Wassers mit der Luft erfolgt.It is an object of the present invention to provide a aerator of the type mentioned which is cheaper to produce than known aerators, but which still ensures that the water is mixed intensively with the air.

Gelöst wird die Aufgabe dadurch, daß mindestens eine aus zwei Sieben gebildete linsenartige Siebanordnung vorge­sehen ist.The object is achieved in that at least one lens-like sieve arrangement formed from two sieves is provided.

Aufgrund der linsenartigen Siebanordnung können die bei­den die Siebanordnung bildenden Siebe unmittelbar mit ihren Rändern aufeinandergelegt werden, ohne daß eine Abstandsauf­bördelung jedes einzelnen Siebes erforderlich ist. Jedes Sieb weist eine gekrümmte Oberfläche auf, die beiden Siebe werden derart zur linsenartigen Siebanordnung aneinanderge­fügt, daß die Wölbungen der Siebe voneinander wegweisen. Die Herstellung der einzelnen Siebe ist denkbar einfach, es ist ausschließlich erforderlich, die einzelnen Siebe auszu­stanzen und in einer Form mit der Wölbung zu versehen.Because of the lens-like sieve arrangement, the two sieves forming the sieve arrangement can be placed directly on top of one another with their edges without the need to flare each individual sieve. Each sieve has a curved surface, the two sieves are joined together to form the lens-like sieve arrangement in such a way that the curvatures of the sieves point away from one another. The production of the individual sieves is very simple, it is only necessary to punch out the individual sieves and to provide the curvature in one form.

Die Siebe können beispielsweise aus Metall oder Kunst­stoff hergestellt sein, sie können ein Maschengitter oder aber ein Lochfeld aufweisen. Versuche haben gezeigt, daß sich optimale Wasser-Luft-Gemische dann ergeben, wenn die Siebanordnung durch ein grobes und ein feines Sieb gebildet ist, wobei das grobe Sieb außen und das feine Sieb innen angeordnet ist. Selbst bei zwei groben Sieben ist jedoch eine ausreichend gute Strahlbildung zu verzeichnen. Zur optimalen Bildung eines Wasser-Luft Gemisches reicht es völlig aus, wenn eine einzige linsenartige Siebanordnung vorgesehen ist.The screens can be made of metal or plastic, for example, they can have a mesh or a perforated field. Experiments have shown that optimal water-air mixtures result when the sieve arrangement is formed by a coarse and a fine sieve, the coarse sieve being arranged on the outside and the fine sieve on the inside. Even with two coarse sieves, however, there is a sufficiently good jet formation. It is sufficient for the optimal formation of a water-air mixture completely off if a single lens-like sieve arrangement is provided.

Durch eine bevorzugte Anordnung des groben Siebes außen läßt sich bei dem erfindungsgemäßen Perlator eine verlänger­te Lebensdauer infolge einer verzögerten Verkalkung des gro­ben Siebes verzeichnen, da dieses nach dem Unterbrechen des Wasserdurchlaufs durch den Perlator erstens nur geringere Mengen an Wasser zurückhält, und zum anderen die sich durch Verdunstung des Adhäsionswassers bildenden Kalkansätze die größeren Maschen wesentlich langsamer verlegen.A preferred arrangement of the coarse sieve on the outside of the aerator according to the invention results in a longer service life due to a delayed calcification of the coarse sieve, since after the water flow has been interrupted by the aerator, it firstly retains only small amounts of water and, on the other hand, it is retained Evaporation of the lime deposits that form the adhesion water, move the larger meshes much more slowly.

Besonders kostengünstig lassen sich die Siebe herstellen und die Siebanordnung bilden, wenn zwei eine gleichge­richtete Wölbung aufweisende Siebe im Bereich deren Kan­ten mittels eines Steges verbunden sind und die linsenar­tige Siebanordnung durch ein Zusammenklappen der Siebe gebildet wird. Die mittels des Steges verbundenen Siebe können gleichzeitig durch ein Werkzeug hergestellt wer­den, durch ein Zusammenklappen der Siebe derart, daß die Kanten der Siebe aufeinander zu liegen kommen und die Wöl­bungen der Siebe voneinander wegweisen, wird die Sieb­anordnung gebildet.The sieves can be produced and formed in a particularly cost-effective manner if two sieves with the same curvature are connected in the region of their edges by means of a web and the lens-like sieve arrangement is formed by folding the sieves together. The screens connected by means of the web can simultaneously be produced by a tool, by collapsing the screens in such a way that the edges of the screens come to lie on one another and the curvatures of the screens point away from one another, the screen arrangement is formed.

Perlatoren haben normalerweise oberhalb der Luftschlitze im Gehäuse ein kreisrundes, kappenförmiges, gelöchertes Teil eingesetzt. Das gelöcherte Teil bewirkt, daß bereits vor den Luftschlitzen der Wasserstrahl getrennt wird und es im Bereich der Luftschlitze schon zu einer erhöhten Durch­mischung von Wasser und Luft kommt. Das gelöcherte Teil kann auf seiner der Siebanordnung zugewandten Seite min­destens ein Abstandsstück aufweisen, dessen freies Ende in Anlage mit dem oberen Sieb der Siebanordnung gelangt. Durch die Ausbildung des gelöcherten Teiles mit dem Abstandsstück drückt das Abstandsstück über das obere Sieb der Siebanord­nung auf das untere, äußere Sieb der Siebanordnung, wodurch gewährleistet ist, daß die Siebanordnung definiert im Ge­häuse gehalten wird.Perlators have usually inserted a circular, cap-shaped, perforated part above the air slots in the housing. The perforated part has the effect that the water jet is separated before the air slots and there is already an increased mixing of water and air in the area of the air slots. The perforated part can have at least one spacer on its side facing the sieve arrangement, the free end of which comes into contact with the upper sieve of the sieve arrangement. By forming the perforated part with the spacer, the spacer presses over the upper sieve of the sieve arrangement onto the lower, outer sieve of the sieve arrangement, thereby it is ensured that the screen arrangement is held in a defined manner in the housing.

Eine besonders gute Strahlausbildung unter Verwendung der neuen Siebausbildung ergibt sich in Kombination mit einer Durchflußbegrenzungs- bzw. Durchflußregeleinrichtung ober­halb des gelöcherten Bauteiles.A particularly good beam formation using the new sieve formation results in combination with a flow limitation or flow control device above the perforated component.

Eine solche Durchflußregeleinrichtung besteht vorteilhafter­weise aus einer auf Abstandsrippen auf dem gelöcherten Bau­teil angeordneten, begrenzt flexiblen Scheibe, die mit be­stimmten Aussparungen für einen reduzierten Strömungsquer­schnitt versehen ist. Zweckmäßigerweise sind die Abstands­rippen als integraler Bestandteil auf der Oberseite des ge­löcherten Teiles ausgebildet und verlaufen radial von deren Mitte nach außen. Die Aussparung in der begrenzt flexiblen Scheibe kann vorteilhafterweise als zentrales Loch ausge­bildet sein. Das in das Gehäuse eintretende Wasser gelangt durch das zentrische Loch in den zwischen der Scheibe und dem gelöcherten Teil befindlichen Raum, wird durch die Rippen aufgeteilt, strömt durch das gelöcherte Teil an den Luftschlitzen vorbei, um durch die Siebanordnung durchzu­treten. Aufgrund der zentrischen Anordnung des Loches strömt das Wasser oberhalb der Luftschlitze im wesentlichen in der Mitte des Wasserhahnmundstückes und gelangt erst im Laufe des weiteren Strömungsweges nach außen. Abgesehen von der besseren Vermischung von Wasser und Luft ist es durch die Wahl des Lochdurchmessers der Scheibe möglich, den Durchfluß des Wassers durch das Mundstück des Wasserhahns zu verändern. Eine zusätzliche Regelwirkung kann durch den begrenzt flexiblen Charakter der Scheibe erreicht werden, wenn diese bei erhöhtem Zulaufdruck teilweise in die Strö­mungskanäle zwischen den Abstandsrippen gedrückt wird.Such a flow control device advantageously consists of a disc which is arranged on spaced ribs on the perforated component and has limited flexibility, which is provided with certain recesses for a reduced flow cross section. The spacer ribs are expediently formed as an integral part on the top of the perforated part and extend radially from the center to the outside. The recess in the limited flexible disc can advantageously be designed as a central hole. The water entering the housing passes through the central hole into the space between the disk and the perforated part, is divided by the ribs, flows through the perforated part past the air slots to pass through the screen arrangement. Due to the central arrangement of the hole, the water flows above the louvers essentially in the middle of the faucet mouthpiece and only reaches the outside in the course of the further flow path. Apart from the better mixing of water and air, it is possible to change the flow of water through the mouthpiece of the tap by selecting the hole diameter of the disc. An additional control effect can be achieved through the limited flexible nature of the disk if it is partially pressed into the flow channels between the spacing ribs when the inlet pressure is increased.

In das Gehäuse oberhalb des gelöcherten Teiles bzw. ober­halb der Scheibe ist vorteilhaft ein nach außen gewölb­ tes Sieb, insbesondere ein feines Sieb eingesetzt. Das Sieb dient dazu, im geförderten Wasser befindlichen groben Schmutz zurückzuhalten. Das Sieb sollte so im Gehäuse ange­ordnet sein, daß es einfach zu entnehmen, zu reinigen und wieder einzusetzen ist.In the housing above the perforated part or above the disc, an outward arch is advantageous sieve, in particular a fine sieve. The strainer is used to hold back coarse dirt in the water being pumped. The sieve should be arranged in the housing so that it is easy to remove, clean and reinsert.

Die Erfindung ist anhand der beigefügten Zeichnungen näher erläutert. Es stellt dar:

  • Fig. 1 einen Mittellängsschnitt durch den erfindungs­gemäßen Perlator und
  • Fig. 2 eine Ansicht X des Perlators, wobei jedoch Teile des Perlators entfernt wurden.
The invention is explained in more detail with reference to the accompanying drawings. It shows:
  • Fig. 1 shows a central longitudinal section through the aerator according to the invention and
  • Fig. 2 is a view X of the aerator, but parts of the aerator have been removed.

In Fig. 1 ist ein Perlator 1 dargestellt, der ein zylindri­sches Gehäuse 2 mit Luftschlitzen 3 aufweist. Die Luft­schlitze 3 befinden sich in einer Ebene des Gehäuses 2, es sind eine Vielzahl von Luftschlitzen 3 über den Umfang des Gehäuses 2 verteilt angeordnet. Das Wasser durchfließt das Gehäuse 2 in der Darstellung nach der Fig. 1 von oben nach unten. An seinem unteren Ende weist das Gehäuse einen nach innen gerichteten umlaufenden Ansatz 4 auf. Von diesem An­satz 4 wird eine Siebanordnung 5 gehalten, die bei der Mon­tage von oben durch das Gehäuse 2 gesteckt wird. Die Sieban­ordnung 5 besteht aus zwei Sieben, die linsenartig angeord­net sind, d.h. das obere Sieb 6 weist eine nach oben gerich­tete Wölbung, das untere Sieb 7 eine nach unten gerichtete Wölbung auf. Die umlaufenden Kanten der Siebe 6 und 7 stützen sich im Bereich des Gehäuses 2 aufeinander ab. Wie der Fig. 1 zu entnehmen ist, ist das obere Sieb 6 feinma­schig, das untere Sieb 7 grobmaschig. Die Siebe sind aus einem Metalldraht hergestellt, der Drahtdurchmesser des groben Siebes sollte etwa 0,5 mm betragen bei einer lichten Maschenweite von etwa 0,5 bis 1,5 mm, vorzugsweise jedoch 0,8 bis 1,3 mm, der Durchmesser des Drahtes des feinen Siebes etwa 0,15 bis 0,20 mm bei einer lichten Maschenweite von 0,1 bis 0,2 mm.In Fig. 1, a aerator 1 is shown, which has a cylindrical housing 2 with louvers 3. The air slots 3 are located in one plane of the housing 2, a plurality of air slots 3 are arranged distributed over the circumference of the housing 2. The water flows through the housing 2 in the illustration according to FIG. 1 from top to bottom. At its lower end, the housing has an inward circumferential projection 4. A sieve arrangement 5 is held by this attachment 4, which is inserted through the housing 2 from above during assembly. The sieve arrangement 5 consists of two sieves which are arranged in a lens-like manner, ie the upper sieve 6 has an upward curvature, the lower sieve 7 has a downward curvature. The circumferential edges of the screens 6 and 7 are supported on one another in the area of the housing 2. As can be seen from FIG. 1, the upper sieve 6 has a fine mesh, the lower sieve 7 has a large mesh. The sieves are made of a metal wire, the wire diameter of the coarse sieve should be about 0.5 mm with a clear mesh size of about 0.5 to 1.5 mm, but preferably 0.8 to 1.3 mm, the diameter of the wire of the fine Sieve about 0.15 to 0.20 mm with a mesh size of 0.1 to 0.2 mm.

Das Gehäuse 2 weist im Bereich eines oberen Ansatzes 8 einen größeren Innendurchmesser auf als im Bereich des unteren Ansatzes 4. Das Gehäuse 2 nimmt im Bereich des An­satzes 8 ein kreisrundes, kappenförmiges Teil 9 auf, das eine Vielzahl von den Boden 10 durchsetzenden Löchern 11 aufweist. Auf seiner der Siebanordnung 5 zugewandten Seite besitzt das Teil 9 ein Abstandsstück 12, dessen freies Ende in Anlage mit dem oberen Sieb 6 der Siebanordnung 5 ge­langt. Hierdurch ist gewährleistet, daß bei eingesetztem Teil 9 die Siebanordnung 5 im Perlator 1 definiert gehalten ist.The housing 2 has a larger inner diameter in the area of an upper extension 8 than in the region of the lower extension 4. The housing 2 receives in the region of the extension 8 a circular, cap-shaped part 9 which has a plurality of holes 11 penetrating the bottom 10 . On its side facing the sieve arrangement 5, the part 9 has a spacer 12, the free end of which comes into contact with the upper sieve 6 of the sieve arrangement 5. This ensures that when the part 9 is inserted, the sieve arrangement 5 is held in a defined manner in the aerator 1.

Auf seiner Oberseite weist das Teil 9 fünf strahlenför­mig von der Mitte des Teiles 9 aus verlaufende Rippen 13 auf, auf welchen eine Scheibe 14 mit einem zentrischen Loch 15 angeordnet ist. Die Scheibe 14 liegt dabei nicht nur auf den Rippen 13, sondern gleichfalls auf einem weiteren umlau­fenden Ansatz 16 des Teiles 9. Oberhalb der Scheibe 14 ist ein nach außen gewölbtes feines Sieb 17 angeordnet. Ein elastischer Ring 18, der in das Teil 9 eingeklemmt ist, verhindert, daß das Sieb 17 und die Scheibe 14 ungewollt vom Teil 9 getrennt werden.On its upper side, the part 9 has five ribs 13, which radiate from the center of the part 9 and on which a disc 14 with a central hole 15 is arranged. The disc 14 lies not only on the ribs 13, but also on a further circumferential projection 16 of the part 9. Above the disc 14 there is a fine sieve 17 which is curved outwards. An elastic ring 18, which is clamped in the part 9, prevents the screen 17 and the disc 14 from being unintentionally separated from the part 9.

Bei der in Fig. 2 dargestellten Ansicht X gemäß Darstel­lung nach Fig. 1 wurden der Ring 18, das Feinsieb 17 und die Scheibe 14 weggelassen.In the view X shown in FIG. 2 as shown in FIG. 1, the ring 18, the fine screen 17 and the disk 14 have been omitted.
