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 Strahlregler für Wasserhahnmundstücke, der in ein zylindrisches, am Wasserhahnmundstück befestigbares Außengehäuse einsetzbar ist, mit einem zylindrischen Gehäuse mit in seiner Außenwand angeordneten Luftschlitzen, einem oberhalb der Luftschlitze im zylindrischen Gehäuse angeordneten, gelöcherten Teil sowie mindestens zwei unterhalb der Luftschlitze in das Gehäuse eingesetzten Sieben, von denen das unterste, nach außen weisende Sieb ein verhältnismäßig grobes Sieb ist.The invention relates to a jet regulator for faucet mouthpieces which can be inserted into a cylindrical outer housing which can be fastened to the faucet mouthpiece, with a cylindrical housing with air slots arranged in its outer wall, a perforated part arranged above the air slots in the cylindrical housing and at least two below the air slots in the Sieves inserted into the housing, of which the lowest, outward-facing sieve is a relatively coarse sieve.

Strahlregler dienen dem Zweck, Wasser-LuftGemische aus den Mundstücken von Wasserhähnen austreten zu lassen. Dazu wird Luft seitlich in den Strahlregler eingezogen, die dann mit dem Wasserstrahl vermischt wird, um diesen ergiebiger werden zu lassen und um Fließgeräusche zu dämpfen. Ein Strahlregler der eingangs bezeichneten Art ist beispielsweise aus der US-A 3 531 051 bekannt.Jet regulators serve the purpose of allowing water-air mixtures to emerge from the mouthpieces of taps. To do this, air is drawn into the side of the jet regulator, which is then mixed with the water jet to make it more productive and to dampen flow noises. A jet regulator of the type described in the opening paragraph is known, for example, from US Pat. No. 3,531,051.

Dieser bekannte Strahlregler weist im Austrittsbereich zwei Siebe auf, von denen das äußere zwar als ein relativ grobes Sieb bezeichnet ist, Maschenweitenangaben sind der Druckschrift jedoch nicht zu entnehmen. Beide Siebe sind eben ausgebildet, und das obere Sieb weist eine rechtwinklig nach unten abgewinkelte Bördelkante auf, mit der es zwecks Abstandshaltung auf dem Rand des unteren Siebes aufliegt. Dieser bekannte Strahlregler ist oberhalb der Luftschlitze bereits mit einer durchlöcherten Platte versehen, die den Wasserzufluß in einzelne Düsenstrahlen aufteilt, eine spezielle Einrichtung zur Durchflußmengenbegrenzung oder Durchflußmengenregelung ist jedoch nicht vorgesehen.This known jet regulator has two screens in the outlet area, of which the outer one is referred to as a relatively coarse screen, however, mesh sizes are not given in the document. Both sieves are flat and the upper sieve has a flanged edge which is angled downwards at a right angle and with which it rests on the edge of the lower sieve for the purpose of maintaining distance. This known jet regulator is already provided with a perforated plate above the air slots, which divides the water inflow into individual jet jets, but a special device for flow rate limitation or flow rate control is not provided.

Der US-A 3 851 825 ist ein Wasserstrahlaustrittskopf zu entnehmen, der ein durchlöchertes Teil zur Strahlaufteilung und austrittsseitig mehrere nach außen gewölbte Siebe aufweist, die auch dicht aufeinanderliegen können, warum die Siebe derart ausgebildet sind, ist der Druckschrift jedoch nicht zu entnehmen. Es ist vielmehr angegeben, daß das innerste Sieb sogar grober ausgeführt sein soll als das äußere. Diese bekannte Vorrichtung weist weder eine Lufteinsaugeinrichtung noch eine Durchflußregelung auf.US Pat. No. 3,851,825 shows a water jet outlet head which has a perforated part for the jet distribution and, on the outlet side, a plurality of screens which are curved outwards and which can also lie closely on one another, but the publication does not disclose why the screens are designed in this way. Rather, it is stated that the innermost sieve should be made even coarser than the outer one. This known device has neither an air intake device nor a flow control.

Die bekannten Strahlregler haben sich in der Praxis durchaus bewährt. Nachteilig ist bei ihnen jedoch, daß die Herstellung der Abstandsaufbördelung der einzelnen Siebe kostenintensiv ist und außerdem die Außensiebe sich mit der Zeit verlegen, da bei guter Strahlqualität verhältnismäßig feinmaschige Siebe erforderlich sind.The known jet regulators have proven their worth in practice. The disadvantage with them, however, is that the production of the flanging of the spacing of the individual screens is cost-intensive and, in addition, the outer screens move over time, since relatively good-mesh screens are required with good jet quality.

Es ist Aufgabe vorliegender Erfindung, einen Strahlregler der genannten Art zu schaffen, der billiger als bekannte Strahlregler herzustellen ist, dabei jedoch nach wie vor gewährleistet ist, daß eine intensive Vermischung des Wassers mit der Luft bei sparsamem Wasserverbrauch erfolgt, ohne daß die Siebe zum schnellen Verlegen neigen.It is an object of the present invention to provide a jet regulator of the type mentioned, which is cheaper to produce than known jet regulators, but which still ensures that intensive mixing of the water with the air takes place with economical water consumption without the sieves becoming too fast Tend to be embarrassed.

Gelöst wird die Aufgabe dadurch, daß oberhalb des gelöcherten Teiles eine Durchflußbegrenzungs-oder Durchflußregeleinrichtung vorgesehen ist, und daß die mindestens zwei Siebe aus mindestens einer aus jeweils zwei Sieben gebildeten, linsenartigen Siebanordnung bestehen, wobei zumindest das untere oder Außensieb dieser mindestens einen Siebanordnung ein Grobsieb mit einer lichten Maschenweite von 0,8 bis 1,5 mm ist.The object is achieved in that a flow limitation or flow control device is provided above the perforated part and in that the at least two sieves consist of at least one lens-like sieve arrangement formed from two sieves each, at least the lower or outer sieve of this at least one sieve arrangement being a coarse sieve with a mesh size of 0.8 to 1.5 mm.

Durch die Kombination einer Durchflußbegrenzungs- bzw. Durchflußregeleinrichtung oberhalb des gelöcherten Bauteiles mit der speziellen Siebanordnung ergibt sich eine besonders gute Strahlausbildung und Standzeit für die Siebe.The combination of a flow limitation or flow control device above the perforated component with the special sieve arrangement results in a particularly good beam formation and service life for the sieves.

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 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 them with a curvature in a mold.

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 screen arrangement is formed by a coarse and a fine screen, the coarse screen being arranged on the outside and the fine screen on the inside. Even with two coarse sieves, however, there is a sufficiently good jet formation. For the optimal formation of a water-air mixture, it is entirely sufficient if a single lenticular sieve arrangement is provided.

Durch die Anordnung des groben Siebes außen läßt sich bei dem erfindungsgemäßen Strahlregler eine verlängerte Lebensdauer infolge einer verzögerten Verkalkung des groben Siebes verzeichnen, da dieses nach dem Unterbrechen des Wasserdurchlaufs durch den Strahlregler erstens nur geringere Mengen an Wasser zurückhält, und zum anderen die sich durch Verdunstung des Adhäsionswassers bildenden Kalkansätze die größeren Maschen wesentlich langsamer verlegen.The arrangement of the coarse strainer on the outside of the jet regulator 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 jet regulator, it firstly retains only small amounts of water and, secondly, it evaporation of the lime deposits that form the adhesion water, lay 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.

Die 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.The flow control device advantageously consists of a disc which is arranged on spacer ribs on the perforated component and is of limited flexibility, which is provided with certain recesses for a reduced flow cross section. The spacer ribs are expediently formed as an integral component on the upper side 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 disc and the perforated part, is divided by the ribs, flows through the perforated part past the air slots to pass through the sieve arrangement. Due to the central arrangement of the hole, the water flows above the air slots 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, the choice of the hole diameter of the disc makes it possible to change the flow of water through the mouthpiece of the tap. An additional control effect can be achieved by 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 gewölbtes 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.An outwardly curved sieve, in particular a fine sieve, is advantageously inserted into the housing above the perforated part or above the disk. 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 Strahlregler und
  • Fig. 2 eine Ansicht X des Strahlreglers, wobei jedoch Teile des Strahlreglers 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 jet regulator according to the invention and
  • Fig. 2 is a view X of the jet regulator, but parts of the jet regulator have been removed.

In Fig. 1 ist ein Strahlregler 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 Sileb 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 0,8 bis 1,5 mm, der Durchmesser des Drahtes des feinen Siebes etwa 0,15 mm bis 0,20 mm bei einer lichten Maschenweite von 0,1 bis 0,2 mm.In Fig. 1, a jet regulator 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, i.e. 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 in FIG. 1, the upper sileb 6 is fine-meshed, the lower sieve 7 is coarse-meshed. 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 0.8 to 1.5 mm, the diameter of the wire of the fine sieve about 0.15 mm 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 Strahlregler 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 screen arrangement 5 is held in a defined manner in the jet regulator 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.
