Description

Die Erfindung betrifft einen Strahlregler mit einem Strahlreglergehäuse, in dessen Gehäuseinnenraum eine Lochplatte mit einer Mehrzahl von Durchflußlöchern zum Aufteilen des durchströmenden Wassers vorgesehen ist, auf deren Abströmseite der Lochplatte im Strahlreglergehäuse und/oder an der Abströmstirnfläche des Strahlreglergehäuses Strömungshindernisse vorgesehen sind, die dort in einem zentralen oder mittigen Bereich angeordnet oder konzentriert sind und die das durchströmende Wasser in eine äußere Ringzone umlenken. Strahlregler der eingangs erwähnten Art sind bereits in den verschiedensten Ausführungen bekannt. Solche Strahlregler werden an dem Wasserauslauf einer sanitären Auslaufarmatur montiert, um dort einen homogenen und seitlich nicht-spritzenden Wasserstrahl zu erzeugen. Man hat auch Strahlregler geschaffen, die den austretenden Wasserstahl belüften und das durchströmende Wasser dazu mit der Umgebungsluft durchmischen sollen.The invention relates to a jet regulator with a jet regulator housing, in the housing interior of a perforated plate is provided with a plurality of Durchflußlöchern for dividing the water flowing through, are provided on the downstream side of the perforated plate in the jet regulator housing and / or at the Abströmstirnfläche the jet regulator flow obstacles, there in a central or central area are arranged or concentrated and divert the water flowing through into an outer annular zone. Jet regulator of the type mentioned are already known in various designs. Such jet regulators are mounted on the water outlet of a sanitary outlet fitting to produce a homogeneous and laterally non-splashing water jet there. It has also created aerator, which aerate the escaping water steel and mixing the water flowing through it with the ambient air.

Aus der DE 10 2006 057 795 B3 die als nächster Stand der Technik angesehen werden kann, kennt man bereits einen Strahlregler der eingangs erwähnten Art mit einem Strahlreglergehäuse, in dessen Gehäuseinnenraum eine Lochplatte mit einer Mehrzahl von Durchflusslöchern zum Aufteilen des durchströmenden Wassers vorgesehen ist. Auf der Abströmseite der Lochplatte sind in das Strahlreglergehäuse Einsetzteile eingelegt, die jeweils eine in einer quer zur Durchströmrichtung orientierten Ebene angeordnete Netzstruktur aus einer Schar radialer Stege aufweisen, welche sich an Kreuzungsknoten mit einer Schar konzentrischer Stege kreuzen. Auf der Zuströmseite der Lochplatte ist ein Filtersieb vorgesehen, das eine zentral angeordnete Schmutzauslassöffnung mit einem im Vergleich zu den Sieböffnungen des Filtersiebes vergrößerten lichten Öffnungsquerschnitt hat. Die Schmutzauslassöffnung ist mit Hilfe des Ventilkörpers eines Ventils verschließbar, das von seiner Offenstellung unter dem Staudruck des zuströmenden Wassers gegen die Rückstellkraft einer Rückstellfeder in seine Schließstellung bewegbar ist und vom zuströmenden Wasser stets in dieser Schließstellung gehalten wird. An den Ventilkörper dieses Ventils ist ein Führungszapfen angeformt, der eine zentrale Führungsöffnung in der Lochplatte durchsetzt. An dem abströmseitig über die Lochplatte vorstehenden Zapfenende des Führungszapfens ist ein zentrisch orientiertes Gitternetz angeformt, welches in seinem Zentrum weniger Durchflussmöglichkeiten bietet als am äußeren Rand und somit ein Strömungshindernis bildet, welches das durchströmende Wasser in die äußere Ringzone umlenkt. Auch dieser vorbekannte Strahlregler setzt einen gewissen Durchfluss und einen ausreichenden Wasserdruck im Leitungsnetz voraus, damit das durchströmende Wasser den Ventilkörper gegen die Rückstellkraft der Rückstellfeder in die Schließstellung des Ventils drücken kann.From the DE 10 2006 057 795 B3 which can be regarded as the closest prior art, already known a jet regulator of the type mentioned with a jet regulator housing, in the housing interior a perforated plate with a plurality is provided by flow holes for dividing the water flowing through. On the downstream side of the perforated plate insertion parts are inserted into the jet regulator housing, each having a arranged in a direction transverse to the flow plane network structure of a family of radial webs, which intersect at intersection nodes with a family of concentric webs. On the inflow side of the perforated plate, a filter screen is provided, which has a centrally arranged Schmutzauslassöffnung with an enlarged compared to the screen openings of the filter screen clear opening cross-section. The Schmutzauslassöffnung can be closed by means of the valve body of a valve which is movable from its open position under the back pressure of the incoming water against the restoring force of a return spring in its closed position and is always held by the inflowing water in this closed position. On the valve body of this valve, a guide pin is formed, which passes through a central guide opening in the perforated plate. At the outflow side above the perforated plate projecting spigot end of the guide pin a centrally oriented grid is formed, which offers less flow possibilities in its center than at the outer edge and thus forms a flow obstacle, which deflects the water flowing through into the outer annular zone. Also, this previously known jet regulator requires a certain flow and a sufficient water pressure in the pipeline network, so that the water flowing through the valve body can press against the restoring force of the return spring in the closed position of the valve.

Aus der DE 30 00 799 A1 ist bereits ein belüfteter Strahlregler vorbekannt, der in seinem Strahlreglergehäuse eine Lochplatte hat, die eine Vielzahl von Durchflußlöchern aufweist, welche in konzentrischen Lochkreisen auf der Lochplatte angeordnet sind und welche das durch das Strahlreglergehäuse strömende Wasser in eine entsprechende Anzahl von Einzelstrahlen aufteilen sollen. Da die Durchflußlöcher den lichten Durchflußquerschnitt im Bereich der Lochplatte verengen, erfährt das durchströmende Wasser in den Durchflußlöchern eine Geschwindigkeitserhöhung, die gemäß der Bernoullischen Gleichung auf der Abströmseite der Lochplatte einen Unterdruck bewirkt. Durch den auf der Abströmseite der Lochplatte erzeugten Unterdruck wird Umgebungsluft angesaugt, die durch in der Gehäusewandung vorgesehene Belüftungsöffnungen in das Gehäuseinnere des Strahlreglergehäuses eindringen und dort mit dem durchströmenden Wasser vermischt werden kann. Damit das durchströmende Wasser mittels der Lochplatte geräuscharm in Einzelstrahlen aufgeteilt wird, ist bei dem aus DE 30 00 799 A1 vorbekannten Strahlregler unter anderem vorgesehen, dass die Durchflußlöcher einen im Querschnitt mehrkantigen Lochäbschnitt haben, dem ein im Querschnitt zunehmend erweiterter und abströmseitig zylindrischer Lochabschnitt nachgeschaltet ist (vergleiche Figur 4 in DE 30 00 799 A1 ). Durch solche, verschiedene Abschnitte aufweisende Durchflußlöcher wird in den Durchflußlöchern jeweils ein im Querschnitt runder und linear ausströmende Einzelstrahl erzeugt.From the DE 30 00 799 A1 already a ventilated jet regulator is already known, which has in its jet regulator housing a perforated plate having a plurality of flow holes, which in concentric hole circles on the Perforated plate are arranged and which should divide the water flowing through the jet regulator housing into a corresponding number of individual beams. Since the flow-through holes narrow the clear flow area in the area of the perforated plate, the water flowing through in the flow-through holes experiences an increase in speed, which causes a negative pressure on the outflow side of the perforated plate according to the Bernoulli equation. By the negative pressure generated on the downstream side of the perforated plate ambient air is sucked in, which penetrate through openings provided in the housing ventilation openings in the housing interior of the jet regulator housing and mixed there with the water flowing through. Thus, the water flowing through the noise plate is divided into individual beams by means of the perforated plate, is in the off DE 30 00 799 A1 previously provided jet regulator, inter alia, provided that the Durchflußlöcher have a polygonal cross-section Lochäbschnitt, which is followed by a cross-section increasingly extended and downstream cylindrical portion of the hole (see FIG. 4 in DE 30 00 799 A1 ). Through such, different sections having flow holes in each of the flow holes a circular cross-section and linear outflowing single beam is generated.

Aus der EP 1 273 724 B1 (= DE 601 01 909 T2 ) kennt man bereits einen Strahlregler mit einem Strahlreglergehäuse, in dessen Gehäuseinnenraum eine Lochplatte vorgesehen ist, die Durchflußlöcher hat, welche in Durchflußrichtung einen gleichbleibenden lichten Querschnitt aufweisen. Der Lochplatte ist ein Prallkonus in Durchströmrichtung nachgeschaltet, der eine Einschnürung im Durchflußquerschnitt des vorbekannten Strahlreglers bildet. Die in der Lochplatte erzeugten Einzelstrahlen können die Umgebungsluft im Gehäuseinnenraum des Strahlreglergehäuses mit sich reißen und treffen anschließend derart auf der Schrägfläche des Prallkonus auf, dass die belüfteten Einzelstrahlen mit der mitgerissenen Luft aufgebrochen und durchmischt werden.From the EP 1 273 724 B1 (= DE 601 01 909 T2 ) is already known a jet regulator with a jet regulator housing, in the housing interior a perforated plate is provided which has flow holes, which have a constant clear cross-section in the flow direction. The perforated plate is followed by a baffle cone in the flow direction, which forms a constriction in the flow area of the previously known jet regulator. The individual beams generated in the perforated plate can tear the ambient air in the housing interior of the jet regulator housing with him and then meet such on the inclined surface of the impact cone that the aerated individual jets are broken up and mixed with the entrained air.

Die vorbekannten Strahlregler setzen jedoch einen gewissen Durchfluß und einen ausreichenden Wasserdruck im Leitungsnetz voraus, damit auf der Abströmseite der als Strahlzerleger dienenden Lochplatte ein ausreichender Unterdruck erzeugt wird, um Umgebungsluft in den Gehäuseinnenraum des Strahlreglergehäuses zu saugen. Demgegenüber ist der bei geringem Durchfluß und niedrigen Wasserdrücken gebildete Unterdruck meist nicht ausreichend, um die Umgebungsluft mit dem durchströmenden Wasser vermischen zu können.However, the prior art jet regulators require a certain flow and sufficient water pressure in the pipeline network, so that sufficient negative pressure is generated on the downstream side of serving as a jet separator perforated plate to suck ambient air into the housing interior of the jet regulator housing. In contrast, the negative pressure formed at low flow and low water pressures is usually not sufficient to mix the ambient air with the water flowing through can.

Es besteht daher die Aufgabe, einen Strahlregler der eingangs erwähnten Art zu schaffen, der auch bei geringem Durchfluß und/oder niedrigen Wasserdrücken, wie sie beispielsweise auch zu Wassersparzwecken häufig angestrebt werden, einen ausreichend belüfteten und dementsprechend perlend-weichen Wasserstrahl zu erzeugen vermag. Dabei wird auch die Erzeugung eines möglichst voluminösen Strahles angestrebt, der für den Benutzer sich visuell und haptisch nicht vom gewohnten Stand der Technik unterscheidet, wobei der erfindungsgemäße Strahlregler vorzugsweise austauschbar mit den bekannten Strahlreglerausführungen sein soll.It is therefore an object to provide a jet regulator of the type mentioned, which is also at low flow and / or low water pressures, as they are often sought, for example, for water saving purposes, a sufficiently ventilated and accordingly perlender-soft water jet is able to produce. In this case, the generation of a possible voluminous beam is sought, which does not differ visually and haptically from the usual state of the art for the user, the jet regulator according to the invention should preferably be interchangeable with the known jet regulator designs.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei dem Strahlregler der eingangs erwähnten Art insbesondere darin, dass die Lochplatte eine zentrale lochfreie erste Prallfläche hat, die zumindest eine Ringwandung umgrenzt, dass die Ringwandung außenumfangsseitig von einer ringförmig umlaufenden zweiten Prallfläche umgrenzt ist, dass die Ringwandung in radialer Richtung orientierte Durchtrittsöffnungen aufweist, und dass auf der in der Prallflächen-Ebene angeordneten Seite der Durchtrittsöffnungen jeweils ein Durchflussloch der Lochplatte vorgesehen ist.The achievement of this object is in the jet regulator of the type mentioned in particular that the perforated plate has a central hole-free first baffle which bounds at least one annular wall, that the annular wall is bounded on the outer peripheral side of an annular peripheral second baffle that the annular wall in the radial Has directionally oriented passages, and that on the in the Plane surface-level side of the passage openings each have a flow hole of the perforated plate is provided.

Bei dem erfindungsgemäßen Strahlregler sind auf der Abströmseite der Lochplatte im Strahlreglergehäuse und/oder an der Abströmstirnfläche des Strahlreglergehäuses Strömungshindernisse vorgesehen, die dort in einem zentralen oder mittigen Bereich angeordnet oder konzentriert sind und die das durchströmende Wasser in eine äußere Ringzone umlenken, die demgegenüber keine oder eine geringere Anzahl oder Gesamtfläche von Strömungshindernissen aufweist. Um den Strahlregler mit einem Strahlreglergehäuse zu schaffen, das aus Kompatibilitätsgründen in seinen Abmessungen den Abmessungen handelsüblicher Strahlregler entspricht und um dennoch auch bei geringen Durchflüssen einen im Querschnitt vergleichbar voluminös erscheinenden Wasserstrahl zu formen, wird das durchströmende Wasser mittels der Strömungshindernisse von einem zentralen oder mittigen Bereich aus zumindest teilweise auch in eine äußere Ringzone umgelenkt, die den Außenumfang des austretenden Wasserstrahles formt.In the jet regulator according to the invention, flow obstacles are provided on the outflow side of the perforated plate in the jet regulator housing and / or on the Abströmstirnfläche the jet regulator housing, which are arranged or concentrated there in a central or central area and redirect the water flowing through into an outer annular zone, which in contrast no or has a smaller number or total area of flow obstacles. In order to create the jet regulator with a jet regulator housing, which for compatibility reasons corresponds in its dimensions to the dimensions of commercially available jet regulators, and nevertheless to form a water jet with a comparably voluminous cross-section even at low flow rates, the water flowing through it becomes a central or central region by means of the flow obstacles from at least partially deflected into an outer annular zone, which forms the outer periphery of the exiting water jet.

Dabei weist die Lochplatte eine zentrale erste Prallfläche auf, die von zumindest einer Ringwandung umgrenzt wird. Diese Ringwandung hat in radialer Richtung orientierte Durchtrittsöffnungen, die über den Umfang der Ringwandung voneinander beabstandet sind. Über die zentrale erste Prallfläche hinaus ist eine außenseitig um die Ringwandung umlaufende zweite Prallfläche vorgesehen, die vorzugsweise in der Ebene der zentralen ersten Prallfläche angeordnet ist. Bodenseitig und somit auf der in der Prallflächen-Ebene angeordneten Seite der Durchtrittsöffnungen ist jeweils eines der Durchflusslöcher der Lochplatte vorgesehen. Durch diese Umlenkung des anströmenden Wassers im Bereich der Durchflusslöcher wird das Wasser abgebremst, zur Seite hin ausgelenkt und gegebenenfalls durch, in gegensinnige Richtungen aufeinander zuströmende Teilströme durchmischt, um anschließend in Verengung des Durchflussquerschnitts in den Durchflusslöchern wieder eine Geschwindigkeitserhöhung zu erfahren. Gemäß der Bernoullischen Gleichung wird durch diese Geschwindigkeitserhöhung auf der Abströmseite der Lochplatte ein Unterdruck erzeugt, mittels dem Umgebungsluft in den Gehäuseinnenraum des Strahlreglergehäuses eingesaugt werden kann. Der in dem erfindungsgemäßen Strahlregler geformte Wasserstrahl zeichnet sich daher durch ein voluminös erscheinendes Auslaufstrahlbild und durch eine gute Luftdurchmischung des durchströmenden Wassers auch bei geringen Durchflüssen und niedrigen Wasserdrücken aus.In this case, the perforated plate on a central first baffle, which is bounded by at least one annular wall. This annular wall has radially oriented through openings, which are spaced apart from each other over the circumference of the annular wall. Beyond the central first baffle surface, there is provided a second baffle surface which extends around the outside of the ring wall and which is preferably arranged in the plane of the central baffle surface. On the bottom side and thus on the arranged in the baffle plane side of the passage openings each one of the flow holes of the perforated plate is provided. Through this Deflection of the inflowing water in the region of the flow holes, the water is braked, deflected to the side and optionally mixed by, in opposite directions flowing inflow partial streams, and then in the narrowing of the flow cross-section in the flow holes again experience an increase in speed. According to the Bernoulli equation, a vacuum is generated by this speed increase on the downstream side of the perforated plate, by means of which ambient air can be sucked into the housing interior of the jet regulator housing. The water jet formed in the jet regulator according to the invention is therefore distinguished by a voluminous discharge jet pattern and by good air mixing of the water flowing through, even at low flow rates and low water pressures.

Ein vorteilhaftes Ausführungsbeispiel gemäß der Erfindung sieht vor, dass auf der Abströmseite der Lochplatte mit Abstand von dieser am Gehäuseinnenumfang eine umlaufende Prallschräge vorgesehen ist, die den lichten Gehäusequerschnitt in diesem Bereich in Strömungsrichtung zunehmend verengt. Bei dieser vorteilhaften Ausführungsform trifft das aus den Durchflußlöchern austretende und bereits mit Luft angereicherte Wasser mit Abstand nach der Lochplatte auf einer Prallschräge auf, die das bereits derart aufbereitete Wasser noch zusätzlich vermischt und aufteilt, bevor das derart mit Luft angereicherte Wasser als homogener, nicht-spritzender und perlend-weicher Wasserstrahl aus dem Strahlregler austreten kann.An advantageous embodiment according to the invention provides that on the downstream side of the perforated plate at a distance from this on the housing inner circumference a circumferential baffle slope is provided, which increasingly narrows the clear housing cross-section in this area in the flow direction. In this advantageous embodiment, the exiting from the flow holes and already enriched with air water meets at a distance to the perforated plate on a baffle, which additionally mixes and divides the already treated water before the thus enriched with air water as a homogeneous, non- spouting and pearly-soft water jet can escape from the jet regulator.

Eine besonders einfach herstellbare Ausführungsform gemäß der Erfindung sieht vor, dass die Prallschräge die Zuströmseite eines Wandungsabschnitts bildet, der als zumindest eine im Längsschnitt wellenförmige Einschnürung ausgestaltet ist.A particularly easy to manufacture embodiment according to the invention provides that the baffle slope forms the inflow side of a Wandungsabschnitts, which is configured as at least one wavy constriction in longitudinal section.

Dabei kann die Prallschräge als innenumfangsseitige Ausformung oder innenumfangsseitiger Vorsprung der Gehäuseumfangswandung ausgestaltet und mit dem Strahlreglergehäuse oder einem Strahlreglergehäuseteil einstückig verbunden sein.In this case, the impact bevel can be designed as an inner peripheral side projection or inner peripheral side projection of the housing peripheral wall and can be integrally connected to the jet regulator housing or a jet regulator housing part.

Bevorzugt wird jedoch eine Ausführung, bei der die Prallschräge als Wandungsabschnitt eines in das Strahlreglergehäuse einsetzbaren ringförmigen oder hülsenförmigen Einsetzteiles ausgebildet ist.However, an embodiment in which the baffle slope is formed as a wall portion of an insertable into the jet regulator housing annular or sleeve-shaped insert is preferred.

Um auch in das Gehäuseinnere des Strahlreglergehäuses zumindest ein Strahlformteil einsetzen zu können, selbst wenn die als Strahlzerleger dienende Lochplatte an das Strahlreglergehäuse einstückig angeformt ist, ist es vorteilhaft, wenn das Strahlreglergehäuse mehrteilig ausgestaltet ist und zumindest zwei, vorzugsweise lösbar miteinander verbindbare Gehäuseteile hat.In order to use at least one beam molding in the housing interior of the jet regulator housing, even if the perforated plate serving as a jet splitter is integrally formed on the jet regulator housing, it is advantageous if the jet regulator housing is designed in several parts and has at least two, preferably releasably connectable housing parts.

Dabei sehen besonders vorteilhafte Ausführungsformen gemäß der Erfindung, vor, dass die Prallschräge am Gehäuseinnenumfang eines abströmseitigen Gehäuseteiles einstückig angeformt ist und/oder dass die Lochplatte in dem Gehäuseinnenraum eines zuströmseitigen Gehäuseteiles einstückig eingeformt ist.In this case, particularly advantageous embodiments according to the invention, provide that the impact bevel is integrally formed on the housing inner circumference of a downstream housing part and / or that the perforated plate is integrally formed in the housing interior of an inflow-side housing part.

Zusätzlich zu oder vorzugsweise statt einer Prallschräge kann der Lochplatte in Strömungsrichtung wenigstens eine Netz-oder Gitterstruktur nachgeschaltet sein. Das aus den Durchflußlöchern kegelförmig oder konisch austretende und auf der wenigstens einen Netz- oder Gitterstruktur auftreffende Wasser wird dort abgebremst und mit den nebenliegenden zerlegten Anteilen des aus den benachbarten Durchflußlöchern austretenden Wassers zerlegt, um anschließend als weicher Gesamtstrahl aus dem Strahlregler austreten zu können.In addition to or preferably instead of a baffle slope, the perforated plate can be connected downstream of at least one mesh or grid structure in the flow direction. The tapered or conically emerging from the flow holes and impinging on the at least one network or lattice water is braked there and decomposed with the adjacent disassembled portions of emerging from the adjacent flow holes water to then emerge as a soft overall beam from the jet regulator can.

Zwar kann eine solche Gitterstruktur auch durch ein eingelegtes Metallsieb gebildet werden, das aus zwei Scharen vorzugsweise rechtwinklig verwobener Metalldrähte gebildet ist, - bevorzugt wird jedoch eine Ausführungsform, bei der die Netz-oder Gitterstruktur aus zwei Scharen, an Kreuzungsknoten aneinander kreuzenden Stegen gebildet ist. Eine solche Netz-oder Gitterstruktur, die aus zwei Scharen, an Kreuzungsknoten einander kreuzenden Stegen gebildet ist, lässt sich auf einfache Weise auch als Kunststoffspritzgußteil herstellen.Although such a lattice structure can also be formed by a pickled metal screen, which is formed from two sets of preferably rectangularly interwoven metal wires, an embodiment is preferred in which the network or lattice structure is formed from two sets of webs crossing each other at intersecting nodes. Such a network or lattice structure, which is formed from two flocks, at intersection nodes crossing webs, can be produced in a simple manner as a plastic injection molded part.

Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass die wenigstens eine, der Lochplatte in Strömungsrichtung nachgeschaltete Netzstruktur aus radialen Stegen und damit an Kreuzungsknoten kreuzenden konzentrischen Stegen gebildet ist.In this case, a preferred embodiment according to the invention provides that the at least one, the perforated plate in the flow direction downstream network structure of radial webs and thus crossing at crossing nodes concentric webs is formed.

Um die Zerlegung des von der Lochplatte kommenden Wassers noch zusätzlich zu begünstigen, kann es vorteilhaft sein, wenn der Lochplatte in Strömungsrichtung wenigstens zwei voneinander beabstandete Netz- oder Gitterstrukturen nachgeschaltet sind.In order to further promote the decomposition of the water coming from the perforated plate, it may be advantageous if the perforated plate is followed in the direction of flow by at least two network or grid structures spaced apart from one another.

Dabei sieht eine bevorzugte Weiterbildung gemäß der Erfindung vor, dass wenigstens ein Durchflußloch in Strömungsrichtung mit einem radialen Steg der einen Netzstruktur sowie mit einem konzentrischen Steg einer benachbarten Netzstruktur fluchtet.In this case, a preferred development according to the invention provides that at least one flow hole in the flow direction is aligned with a radial web of a network structure and with a concentric web of an adjacent network structure.

Das in der Lochplatte aufgeteilte Wasser strömt aus den Durchflußlöchern der Lochplatte weniger als Einzelstrahl und vielmehr als Sprühkegel aus. Um die aus den Durchflußlöchern austretenden Sprühkegel noch weiter aufzubrechen und aufzuteilen, ist es vorteilhaft, wenn die jeweils mit einem Durchflußloch fluchtenden Stege sich in Strömungsrichtung des wenigstens einen Durchflußloches in den verschiedenen Ebenen dieser Netz- oder Gitterstrukturen überdecken oder kreuzen.The divided in the perforated plate water flows out of the flow holes of the perforated plate less than single jet and rather than spray cone. In order to further break up and divide the spray cones emerging from the flow holes, it is advantageous if each with a flow hole aligned webs overlap or intersect in the flow direction of the at least one Durchflußloches in the various levels of network or grid structures.

Um den erfindungsgemäßen Strahlregler mit vergleichsweise geringem Aufwand beispielsweise aus einzelnen Kunststoffteilen herstellen zu können, kann es vorteilhaft sein, wenn jede Netz- oder Gitterstruktur durch ein in den Gehäuseinnenraum des Strahlreglergehäuses einsetzbares Einsetzteil gebildet ist.In order to be able to produce the jet regulator according to the invention with comparatively little effort, for example, from individual plastic parts, it may be advantageous if each mesh or lattice structure is formed by an insertion part which can be inserted into the housing interior of the jet regulator housing.

Dabei sieht eine bevorzugte Ausführungsform vor, dass jedes Einsetzteil außenumfangsseitig eine umlaufende Ringwandung hat, an welche Stege der Netz- oder Gitterstruktur gehalten und vorzugsweise einstückig angeformt sind.In this case, a preferred embodiment provides that each insert part has on the outer peripheral side a circumferential annular wall, to which webs of the mesh or grid structure are held and preferably integrally formed.

Das Aufbrechen und Zerteilen der aus den Durchflußlöchern der Lochplatte austretenden Sprühkegel wird noch begünstigt, wenn zumindest die konzentrischen Stege und vorzugsweise auch die radialen Stege einer in Strömungsrichtung vorderen Netzstruktur im Vergleich zu den Stegen einer in Strömungsrichtung abströmseitig benachbarten Netzstruktur eine gleiche oder kleinere Stegdicke aufweist.The breaking up and dividing of the spray cone emerging from the throughflow holes of the perforated plate is further promoted if at least the concentric webs and preferably also the radial webs of a network structure in front in the direction of flow has an equal or smaller web thickness compared to the webs of a network structure adjacent downstream.

Die in der Lochplatte vorgesehenen Durchflußlöcher können auf konzentrischen Lochkreisen angeordnet sein. Eine bevorzugte Ausführungsform gemäß der Erfindung sieht jedoch vor, dass die Lochplatte eine zentrale lochfreie Prallfläche hat, die zumindest eine Ringwandung umgrenzt, dass die zumindest eine Ringwandung in radialer Richtung orientierte Durchtrittsöffnungen aufweist, und dass auf der in der Prallflächen-Ebene angeordneten Seite der Durchflußöffnungen jeweils ein Durchflußloch der Lochplatte vorgesehen ist. Das auf diese Weise im Bereich der Ringwandung umgelenkte Wasser wird zunächst abgebremst, zur Seite hin ausgelenkt und durch gegebenenfalls in gegensinnigen Richtungen aufeinander zuströmende Teilströme durchmischt, bevor es durch die Durchflußlöcher der Lochplatte hindurchfließen und auf der Abströmseite der Lochplatte in Form einer entsprechenden Anzahl von Sprühkegeln austreten kann.The flow holes provided in the perforated plate can be arranged on concentric hole circles. However, a preferred embodiment according to the invention provides that the perforated plate has a central hole-free baffle which bounds at least one annular wall, that the at least one annular wall has radially oriented passage openings, and that on the arranged in the baffle plane side of the flow openings in each case a Durchflußloch the perforated plate is provided. The water diverted in this way in the area of the annular wall becomes first braked, deflected to the side and mixed by optionally in opposite directions flowing towards each other streams before it can flow through the through holes of the perforated plate and can emerge on the downstream side of the perforated plate in the form of a corresponding number of Sprühkegeln.

Um das im Gehäuseinnenraum des Strahlreglergehäuses mit Umgebungsluft durchmischte und entsprechend aufgewirbelte Wasser auf der Abströmseite des Strahlreglers wieder zu einem homogenen Gesamtstrahl zu formen und um das aus dem Strahlregler austretende Wasser in einer abströmseitigen Homogenisierungseinrichtung zu einem nicht-spritzend austretenden Wasserstrahl formen zu können, ist es zweckmäßig, wenn die abströmseitige Stirnfläche des Strahlreglergehäuse durch eine Netz-oder Wabenzellenstruktur gebildet ist, und wenn die die abströmseitige Stirnfläche bildende Netz- oder Wabenzellenstruktur entweder mit dem Strahlreglergehäuse unlösbar verbunden und insbesondere einstückig angeformt oder durch ein in das Strahlreglergehäuse einsetzbares Einlegeteil gebildet ist.In order to reshape in the housing interior of the jet regulator housing with ambient air and correspondingly fluidized water on the outflow side of the jet regulator back to a homogeneous overall jet and to be able to shape the emerging from the jet regulator water in a downstream homogenizer to a non-squirting emerging water jet, it is expedient if the outflow-side end face of the jet regulator housing is formed by a net or honeycomb cell structure, and if the net or honeycomb cell structure forming the downstream end face is either inseparably connected to the jet regulator housing and in particular integrally formed or formed by an insert which can be inserted into the jet regulator housing.

Die Vergleichmäßigung des aus dem Strahlregler austretenden Gesamtstrahles wird noch begünstigt, wenn die die abströmseitige Stirnfläche des Strahlreglergehäuses bildenden Netz-oder Wabenzellenstruktur durch Stege gebildet ist, die sich zumindest in einem abströmseitigen Teilbereich in Strömungsrichtung verjüngen.The homogenization of the exiting from the jet regulator overall jet is still favored when the net or honeycomb cell structure forming the downstream end face of the jet regulator housing is formed by webs which taper at least in a downstream portion in the flow direction.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht vor, dass der erfindungsgemäße Strahlregler als belüfteter Strahlregler ausgebildet ist, in dessen Gehäuseinnenraum zumindest eine Belüftungsöffnung mündet, die den Gehäuseinnenraum mit der Atmosphäre verbindet. Damit die zumindest eine Belüftungsöffnung den Gehäuseinnenraum mit der Atmosphäre verbinden kann, kann in einem doppelwandigen Teilbereich des Strahlreglergehäuses oder in einem das Strahlreglergehäuse umgrenzenden Ringspalt wenigstens ein Belüftungskanal vorgesehen sein, der zur Atmosphäre hin offen ausgestaltet ist.A preferred embodiment according to the invention provides that the jet regulator according to the invention is designed as a ventilated jet regulator, in whose housing interior at least one ventilation opening opens, which connects the housing interior with the atmosphere. So that at least one ventilation opening can connect the housing interior with the atmosphere, at least one ventilation channel may be provided in a double-walled portion of the jet regulator housing or in an annular gap surrounding the jet regulator housing, which is designed to be open to the atmosphere.

Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass zumindest ein Durchflussloch der Lochplatte sich zu seiner Abströmseite hin kegelförmig oder konisch erweitert. Bei dieser Ausführungsform hat der erfindungsgemäße Strahlregler ein Strahlreglergehäuse, in dessen Gehäuseinnenraum eine sich beispielsweise über den Gehäusequerschnitt erstreckende Lochplatte vorgesehen ist. Die Lochplatte hat eine Mehrzahl von Durchflusslöchern, die zum Aufteilen des durchströmenden Wassers bestimmt sind. Zumindest eines der in der Lochplatte vorgesehenen Durchflusslöcher erweitert sich zu seiner Abströmseite hin und vorzugsweise bis zur Abströmseite hin zunehmend kegelförmig oder konisch. Durch das kegelförmige oder konische Aufspreizen des aus der Lochplatte austretenden Wassers kann sich dieses selbst bei geringen Durchflüssen und niedrigen Wasserdrücken praktisch über den gesamten Gehäusequerschnitt des Strahlreglergehäuses mit der in das Strahlreglergehäuse eingesaugten Umgebungsluft vermischen.A preferred embodiment according to the invention provides that at least one flow hole of the perforated plate widens conically or conically towards its downstream side. In this embodiment, the jet regulator according to the invention has a jet regulator housing, in the housing interior of which a perforated plate extending, for example, over the housing cross-section is provided. The perforated plate has a plurality of flow holes intended to divide the flowing water. At least one of the flow holes provided in the perforated plate widens increasingly conically or conically towards its downstream side and preferably as far as the downstream side. As a result of the conical or conical spreading of the water emerging from the perforated plate, it can mix with the ambient air sucked into the jet regulator housing, even at low flow rates and low water pressures, practically over the entire housing cross section of the jet regulator housing.

Dabei wird die gute Luftdurchmischung des durchströmenden Wassers auch bei geringen Durchflüssen und niedrigen Wasserdrücken zusätzlich begünstigt, wenn zumindest ein Durchflussloch sich zu seiner Abströmseite hin derart kegelförmig oder konisch erweitert, dass der aus dem Durchflussloch austretende und durch die Kegelform oder die Konizität sich erweiternde Einzelstrahl sich im Gehäuseinnenraum noch vor dem Auftreffen von Einzelstrahlen auf wenigstens ein im Gehäuseinnenraum angeordnetes Strahlformteil mit dem Einzelstrahl wenigstens eines benachbarten Durchflussloches durchmischt.In this case, the good air mixing of the water flowing through is favored even at low flow rates and low water pressures, if at least one flow hole in such a conical or conical widening to its downstream side, that emerging from the flow hole and by the conical shape or conicity widening single beam itself in the housing interior even before the impingement of individual jets on at least one arranged in the housing interior Mixed jet molding with the single jet of at least one adjacent flow hole.

Nachstehend wird die vorliegende Erfindung anhand bevorzugter Ausführungsbeispiele noch näher beschrieben.Further developments according to the invention will become apparent from the claims in conjunction with the figures and the description of the figures.

In den Figuren 1 bis 7 ist ein Ausführungsbeispiel100 eines Strahlreglers dargestellt. Die Strahlregler-Ausführung 100 ist dazu bestimmt, am Wasserauslauf einer sanitären Auslaufarmatur montiert zu werden, um dort einen homogenen und seitlich nicht-spritzenden Wasserstrahl zu formen. Um den Wasserstrahl als perlend-weichen Wasserstrahl austreten zu lassen, ist die Strahlregler-Ausführung 100 als belüfteter Strahlregler ausgebildet, bei dem das durchströmende Wasser mit Umgebungsluft durchmischt und angereichert wird.In the FIGS. 1 to 7 an embodiment 100 of a jet regulator is shown. The jet regulator version 100 is intended to be mounted on the water outlet of a sanitary spout to form a homogeneous and laterally non-splashing jet of water there. In order to allow the jet of water to emerge as a soft-sparkling water jet, the jet regulator design 100 is designed as a ventilated jet regulator, in which the water flowing through is mixed with ambient air and enriched.

Die Strahlregler-Ausführung 100 weist ein hülsenförmiges und im Querschnitt rundes Strahlreglergehäuse 2 auf.The jet regulator embodiment 100 has a sleeve-shaped and in cross section round jet regulator housing 2.

Die Strahlregler-Ausführung 100 in den Figuren 1 bis 7 ist mit einem hier nicht weiter dargestellten hülsenförmigen Auslaufmundstück am Wasserauslauf der Auslaufarmatur zu montieren, nachdem der Strahlregler 100 von der zuströmseitigen Hülsenöffnung des Auslaufmundstücks aus in dessen Hülseninnenraum eingesetzt wurde, bis ein Ringabsatz 4 am Außenumfang des Strahlreglergehäuses 2 auf einen im Auslaufmundstück innenumfangsseitig angeordneten Auflager aufliegt.The jet regulator version 100 in the FIGS. 1 to 7 is to be mounted with a sleeve-shaped outlet nozzle not shown here at the water outlet of the outlet fitting after the jet regulator 100 has been inserted from the inflow side sleeve opening of the outlet mouthpiece in the sleeve interior until a ring shoulder 4 rests on the outer periphery of the jet regulator housing 2 on an inner peripheral side arranged in the outlet nozzle support ,

Im Gehäuseinnenraum des Strahlreglers 100 ist eine Lochplatte 5 vorgesehen, die eine Mehrzahl von Durchflußlöchern 6 trägt.In the housing interior of the jet regulator 100, a perforated plate 5 is provided, which carries a plurality of Durchflußlöchern 6.

Zumindest ein Durchflußloch 6 und vorzugsweise alle Durchflußlöcher 6 der Lochplatte 5 erweitern sich zumindest in einem abströmseitigen Teilbereich zu ihrer Abströmseite hin kegelförmig oder konisch. Die in der Lochplatte 5 vorgesehenen Durchflußlöcher 6 sind zum Aufteilen des durchströmenden Wassers bestimmt. Durch das kegelförmige oder konische Aufspreizen des aus der Lochplatte austretenden Wassers kann sich dieses selbst bei geringen Durchflußleistungen und niedrigen Wasserdrücken praktisch über den gesamten Querschnitt des Strahlreglergehäuses 2 mit der in das Strahlreglergehäuse eingesaugten Umgebungsluft vermischen.At least one through-hole 6 and preferably all through-holes 6 of the perforated plate 5 extend conically or conically at least in an outflow-side partial region to their downstream side. The provided in the perforated plate 5 through holes 6 are intended for dividing the water flowing through. Due to the conical or conical spreading of the water emerging from the perforated plate, it can mix with the ambient air sucked into the jet regulator housing, even at low flow rates and low water pressures practically over the entire cross section of the jet regulator housing 2.

Dabei erweitern sich die Durchflußlöcher 6 derart kegelförmig oder konisch, dass der aus den Durchflußlöchern 6 austretende und durch die Kegelform oder die Konizität sich erweiternde Wasserstrahl sich im Gehäuseinnenraum noch vor dem Auftreffen von Einzelstrahlen auf wenigstens ein im Gehäuseinnenraum angeordnetes Strahlformteil mit dem Einzelstrahl wenigstens eines benachbarten Durchflußloches durchmischt.The flow holes 6 extend conically or conically in such a way that the water jet emerging from the flow holes 6 and widening due to the conical shape or conicity becomes at least one adjacent one in the interior of the housing prior to the impact of individual jets on at least one beam molding arranged in the interior of the housing Durchflußloches mixed.

In den Figuren 2 und 3 ist erkennbar, dass die in der Strahlregler-Ausführung 100 vorgesehene Lochplatte 2 eine zentrale erste Prallfläche 14 hat, die von zumindest einer Ringwandung 15 umgrenzt wird. Diese Ringwandung 15 weist in radialer Richtung orientierte Durchtrittsöffnungen 16 auf, die hier über den Umfang der Ringwandung 15 voneinander beabstandet sind. Bodenseitig und somit auf der in der Prallflächen-Ebene angeordneten Seite der Durchtrittsöffnungen 16 ist jeweils eines der Durchflußlöcher 6 der Lochplatte 2 vorgesehen. Durch diese Umlenkung des anströmenden Wassers im Bereich der Durchflußlöcher 6 wird das Wasser abgebremst, zur Seite hin ausgelenkt und gegebenenfalls durch, in gegensinnige Richtungen aufeinander zuströmende Teilströme durchmischt, um anschließend in Folge der Verengung des Durchflußquerschnitts in den Durchflußlöchern 6 wieder eine Geschwindigkeitserhöhung zu erfahren. Gemäß der Bernoullischen Gleichung wird durch diese Geschwindigkeitserhöhung auf der Abströmseite der Lochplatte 5 ein Unterdruck erzeugt, mittels dem Umgebungsluft in den Gehäuseinnenraum des Strahlreglergehäuses 2 eingesaugt werden kann. In der Gehäuseumfangswandung des Strahlreglergehäuses 2 ist dazu zumindest eine auf der Abströmseite der Lochplatte 5 im Gehäuseinnenraum mündende Belüftungsöffnung 17 vorgesehen. Über die zentrale Prallfläche 14 hinaus kann zumindest eine, hier außenseitig umlaufende zweite Prallfläche 29 vorgesehen sein, die vorzugsweise in der Ebene der zentralen Prallfläche 14 angeordnet ist.In the FIGS. 2 and 3 It can be seen that the perforated plate 2 provided in the jet regulator embodiment 100 has a central first baffle surface 14, which is delimited by at least one annular wall 15. This annular wall 15 has oriented in the radial direction through openings 16, which are spaced apart here over the circumference of the annular wall 15 from each other. On the bottom side and thus on the arranged in the baffle plane side of the passage openings 16 each one of the through holes 6 of the perforated plate 2 is provided. By this deflection of the inflowing water in the region of the flow holes 6, the water is braked, deflected to the side and optionally mixed by, in opposite directions to each other inflowing streams, to subsequently in sequence the constriction of the flow area in the flow holes 6 again experience an increase in speed. According to the Bernoulli equation, a vacuum is generated by this speed increase on the outflow side of the perforated plate 5, by means of which ambient air can be sucked into the housing interior of the jet regulator housing 2. In the housing peripheral wall of the jet regulator housing 2, at least one ventilation opening 17 which opens out on the outflow side of the perforated plate 5 in the interior of the housing is provided for this purpose. In addition to the central baffle 14, at least one second baffle 29, which extends around the outside on the outside, may be provided, which is preferably arranged in the plane of the central baffle 14.

Bei der in den Figuren 1 bis 7 gezeigten Strahlreglerausführung 100 durchsetzen die Belüftungsöffnungen 17 das Strahlreglergehäuse 2 in radialer Richtung und sind an der Außenseite des Strahlreglergehäuses 2 mit einem Belüftungskanal verbunden, der als Ringspalt zwischen dem Gehäuseaußenumfang des Strahlreglergehäuses 2 und dem Innenumfang des Auslaufmundstücks gebildet wird und der zur abströmseitigen Stirnseite von Auslaufmundstück und Strahlregler100 zur Atmosphäre hin offen ist.In the in the FIGS. 1 to 7 shown jet regulator embodiment 100 enforce the ventilation openings 17, the jet regulator housing 2 in the radial direction and are connected to the outside of the jet regulator housing 2 with a ventilation channel, which is formed as an annular gap between the housing outer circumference of the jet regulator housing 2 and the inner circumference of the outlet nozzle and the downstream end of outlet nozzle and Jet regulator 100 is open to the atmosphere.

Die in den Figuren 1 bis 7 gezeigte Strahlregler-Ausführung 100 weist auf der Abströmseite der Lochplatte 2 mit Abstand von dieser am Gehäuseinnenumfang eine umlaufende Prallschräge 19 auf, die den lichten Gehäusequerschnitt in diesem Bereich in Strömungsrichtung zunehmend verengt. Diese Prallschräge 19 wird durch die Zuströmseite eines als im Längsschnitt wellenförmige Einschnürung ausgestalteten Wandungsabschnitt gebildet. Der die Prallschräge 19 aufweisende Wandungsabschnitt ist hier als ein in das Strahlreglergehäuse 2 einsetzbares ring- oder hülsenförmiges Einsetzteil 20 ausgestaltet.The in the FIGS. 1 to 7 shown jet regulator embodiment 100 has on the downstream side of the perforated plate 2 at a distance from this on the housing inner circumference a circumferential baffle slope 19, which increasingly narrows the clear housing cross-section in this area in the flow direction. This baffle slope 19 is formed by the inflow side of a wall section designed as a wavy constriction in longitudinal section. The wall portion having the baffle slope 19 is here as an insertable into the jet regulator housing 2 ring or sleeve-shaped insert 20th designed.

In Figur 5 wird deutlich, dass die abströmseitige Stirnfläche des Strahlreglers 100 durch eine Netzstruktur 22 oder eine Wabenzellenstruktur gebildet ist. Während die die abströmseitige Stirnfläche des Strahlreglers 100 bildende Netz- oder Wabenzellenstruktur 22 mit dem Strahlreglergehäuse 2 unlösbar verbunden ist, kann bei einer anderen, hier nicht weiter dargestellten Strahlregler-Ausführung die Auslaufstruktur durch ein in das Strahlreglergehäuse 2 einsetzbares Einlegeteil gebildet sein. Aus einem Vergleich der Figuren 2 und 4 ist erkennbar, dass die die abströmseitige Stirnfläche des Strahlreglers 100 bildende Netzstruktur 22 durch radiale und konzentrische Stege 24, 25 gebildet ist, die sich zumindest in einem abströmseitigen Teilbereich in Strömungsrichtung verjüngen. Da diese Stege 24, 25 sich zumindest in einem abströmseitigen Teilbereich in Strömungsrichtung verjüngen, wird eine Homogenisierung und Vergleichmäßigung des durch die Netzstruktur aus dem Strahlreglergehäuse 2 austretenden Wassers in Form eines homogenen Gesamtstrahles zusätzlich begünstigt.In FIG. 5 It is clear that the downstream end face of the jet regulator 100 is formed by a mesh structure 22 or a honeycomb cell structure. While the network or honeycomb cell structure 22 forming the outflow-side end face of the jet regulator 100 is permanently connected to the jet regulator housing 2, in another jet regulator embodiment not shown here, the outlet structure can be formed by an insert part which can be inserted into the jet regulator housing 2. From a comparison of FIGS. 2 and 4 It can be seen that the network structure 22 forming the outflow-side end face of the jet regulator 100 is formed by radial and concentric webs 24, 25 which taper at least in an outflow-side subregion in the flow direction. Since these webs 24, 25 taper in the flow direction at least in a downstream part, homogenization and equalization of the water emerging from the jet regulator housing 2 by the network structure is additionally promoted in the form of a homogeneous overall jet.

In den Figuren 4 und 5 wird deutlich, dass auf der Abströmseite der Lochplatte im Strahlreglergehäuse und/oder - wie hier - an der Abströmstirnfläche des Strahlreglergehäuses 2 Strömungshindernisse vorgesehen sein können, die dort in einem zentralen oder mittigen Bereich angeordnet oder konzentriert sind und die das durchströmende Wasser in eine äußere Ringzone umlenken, die demgegenüber keine oder eine geringere Anzahl oder Gesamtfläche von Strömungshindernissen aufweist. Bei dem in den Figuren 4 und 5 gezeigten Strahlregler 100 werden diese Strömungshindernisse durch die konzentrischen Stege 25 gebildet, die an der Abströmstirnfläche des Strahlreglergehäuses 2 auf einen zentralen oder mittigen Bereich konzentriert sind, während eine äußere Ringzone frei von solchen konzentrischen Stegen ist.In the FIGS. 4 and 5 It is clear that 2 flow obstacles can be provided on the downstream side of the perforated plate in the jet regulator housing and / or - as here - at the Abströmstirnfläche the jet regulator housing, which are arranged or concentrated there in a central or central area and the water flowing through into an outer annular zone deflect, which in contrast has no or a smaller number or total area of flow obstacles. In the in the FIGS. 4 and 5 shown jet regulator 100, these flow obstacles are formed by the concentric webs 25, which at the Abströmstirnfläche the jet regulator housing 2 to a central or central Area are concentrated, while an outer ring zone is free of such concentric webs.

In Figur 5 wird deutlich, dass das Strahlreglergehäuse 2 hier durch zwei miteinander lösbar verbindbare und vorzugsweise miteinander verrastbare Gehäuseteile 26, 27 gebildet ist, von denen hier das zuströmseitig vordere Gehäuseteil 26 mit der Lochplatte 6 einstückig verbunden ist. Damit die im Wasser eventuell mitgeführten Schmutzpartikel nicht die ordnungsgemäße Funktion des Strahlreglers beeinträchtigen können, ist dem Strahlreglergehäuse 2 ein Vorsatz- oder Filtersieb 28 vorgeschaltet, das hier lösbar am zuströmseitigen Gehäuseteil 26 gehalten ist. Dieses Vorsatz- oder Filtersieb 28 weist eine Vielzahl, im Querschnitt runder oder eckiger und insbesondere sechseckiger Filter- oder Sieböffnungen auf.In FIG. 5 It is clear that the jet regulator housing 2 is formed here by two housing parts 26, 27 which can be detachably connected to one another and are preferably latchable with one another, of which the front housing part 26 on the inflow side is integrally connected to the perforated plate 6. So that the dirt particles possibly entrained in the water can not impair the proper functioning of the jet regulator, the jet regulator housing 2 is preceded by an attachment or filter screen 28, which is held detachably on the inflow-side housing part 26 here. This attachment or filter screen 28 has a multiplicity of round or rectangular, in particular hexagonal, filter or sieve openings.
