- the jet channels open into a portion of the jet regulator housing on the outlet side and if this outlet-side section has a clear housing cross-section that widens in the outlet direction.
- the jet channels still open in the interior of the jet regulator housing in a partial area on the outlet side, where they can, for example, combine to form an annular wall formed from a thin band of water.
- this ring wall still spreads slightly after emerging from the jet regulator housing, whereby this ring wall is maintained over a comparatively long distance of the emerging water jet without the water collapsing into an unclean and disordered jet pattern .
- the stability of the individual spray jets or the annular wall formed here from the individual jets is maintained over a comparatively long distance even after they emerge from the jet regulator housing, if a profile is provided in the outlet-side section of the jet regulator housing on the inside circumference, which is formed by molding and molding oriented in the direction of flow is formed.

- the indentations 22 formed between two adjacent protrusions 23 taper in the outlet direction in such a way that that in the rotational position according to FIG Figure 2 generated spray jet can spread further until it emerges from the jet regulator housing.
- the indentations and formations 22, 23 form guide ribs and guide grooves on the inner circumference of the housing, which further promote the spreading of each individual jet, so that an outlet area that widens conically outward is created, which gives the spray jet a direction diverging with respect to the jet regulator's longitudinal axis.
- outlet-side section of the second housing part 6 has a clear housing cross-section widening in the outlet direction and that a sharp tear-off edge is provided on the inner circumference of this outlet-side section.
- the splitter openings 8 of the jet splitter 7 represent cross-sectional constrictions, the individual jets formed in the splitter openings 8 experience an increase in speed which, according to the Bernoulli equation, leads to a negative pressure on the outflow side of the jet splitter 7.
- the negative pressure formed on the outflow side of the jet splitter 7 leads to the fact that ambient air is sucked into the interior of the jet regulator housing via the jet channels 9, which are formed there with the individual jets to form a homogeneous, non-spraying and pearly-soft overall jet.
- the mixing space formed between the insert part 24 and the downstream end face of the pot-shaped jet splitter section 17 is reduced by the cup-shaped design of the jet splitter 7 in such a way that a comparatively small mixing chamber is formed in which no undesired resonances can occur.
- the good mixing of the ambient air sucked into the interior of the housing with the water flowing through the jet regulator 2 is additionally promoted by the lattice or network structure of the insert part 24 which is arranged on the outflow side of the mixing chamber and is inserted into the interior of the jet regulator housing.
- the flow rate regulator 4 can be inserted into the first housing part 5 up to a support 25, 25 '.

- the flow rate regulator 4, 4 ' here has at least one annular gap 26, 26', in each of which an annular throttle body 27, 27 'made of elastic material is inserted.
- the at least one annular gap 26, 26 ' has on its inside and / or outside circumferential wall a control profile, between which and the elastic throttle body 27, 27' a control gap remains, which narrows under the increasing pressure of the inflowing water in such a way that the per unit time flowing water volume is set to a predetermined maximum value.
- the insert unit 1 'shown can be mounted on the water outlet of a sanitary water outlet fitting (not shown here) with the aid of an outlet mouthpiece 28'.
- the outlet mouthpiece 28 ' is formed at least in two parts and has an inflow-side and an outflow-side section 32', 33 ', which sections 32', 33 'can be rotatably connected to one another.
- An internal or - as here - external thread 34 ' is provided on the inflow-side section 32' of the outlet mouthpiece 28 ', which can be mounted in a corresponding external or internal thread on the water outlet.
- the sections 32 ', 33' of the outlet mouthpiece 28 ' which are rotatably connected to one another are each designed in the form of a sleeve, their sleeve interiors merging into one another.
- the jet regulator 2 ' is inserted in the sleeve interior of the outlet mouthpiece 28' and its sections 32 ', 33'.
- the jet regulator 2 ' can also be switched between two discharge jet images.
- the jet regulator 2 ' also has two housing parts 5', 6 'which can be rotated relative to one another. While the inflow-side first housing part 5 'is held firmly at the water outlet with the aid of the section 32', the outflow-side second housing part 6 'is rotatably connected to the section 33' of the outlet mouthpiece 28 'serving as a handle such that the second housing part 6' relative to the first housing part 5 'can be rotated.
- steel channels 9' are provided which are preferably evenly spaced apart from one another in the circumferential direction and which capture the individual jets coming from the splitting openings 8 'of the jet splitter 7'.
- the second housing part 6 ' is formed here from two separate parts, of which the inner sleeve 19' is inserted into an outer sleeve 42 '.
- the jet regulator 2 ' In the annular space located between the jet channels 9 'and the spray nozzles 35', the jet regulator 2 'has at least one ring insert 36' which has a lattice or network structure and which is intended to serve as a flow straightener which compares the water flowing through.
- this lattice structure is formed by radial webs which delimit flow holes between them. Since at least the inner portion of the peripheral walls surrounding the spray nozzles 35 'is directed obliquely outwards, those which emerge from the spray nozzles 35' become visibly separate Individual jets are deflected obliquely outwards, so that a ring-shaped circumferential discharge jet image is formed which is formed from individual jets flowing away.
- the individual jets emerging from the splitter openings 8 ' are each guided over a deflection bevel 37' which, in this second rotational position, directs the individual jets formed in the splitter openings 8 'radially towards the central outlet opening 10' redirect inwards.
- One of the deflection slopes 37 ' is provided between adjacent beam channels 9'.
- a fin or fin-shaped flow divider 44 ' is provided in each of the deflection bevels 37', which already causes a first division of the inflowing water.
- the fin-shaped flow dividers 44 ' divide the water diverted radially inwards at the deflection slopes 37' into at least two partial streams, the partial streams diverted radially inwards in this way in each case striking the pins 38 'projecting on the outflow side of the jet splitter 7' and there are divided again in such a way that the water flowing through the jet regulator 1 ′ is mixed particularly well with the ambient air.

Description
Die Erfindung betrifft einen Strahlregler, der wahlweise zwischen wenigstens zwei Auslaufstrahlbildern umschaltbar ist und der dazu ein Strahlreglergehäuse mit zumindest zwei relativ zueinander verdrehbaren Gehäuseteilen hat, von denen ein zuströmseitiges erstes Gehäuseteil am Wasserauslauf einer sanitären Auslaufarmatur drehfest montierbar ist und von denen ein abströmseitiges zweites Gehäuseteil mindestens an seinem abströmseitigen Gehäuseaußenumfang als Handhabe ausgebildet oder mit einer Handhabe verbunden ist, wobei das erste Gehäuseteil einen Strahlzerleger mit mehreren Zerlegeröffnungen hat, wobei am Gehäuseinnenumfang des zweiten Gehäuseteiles voneinander beabstandete Strahlkanäle vorgesehen sind, wobei die von den Zerlegeröffnungen kommenden Einzelstrahlen in einer ersten Drehstellung der Gehäuseteile durch die Strahlkanäle geführt und zu einem ringförmig umlaufenden Auslaufstrahlbild geformt und in einer zweiten Drehstellung im Gehäuseinneren des Strahlreglers zu einer zentralen Auslauföffnung des Strahlreglergehäuses umgelenkt werden, wobei der Strahlzerleger zwei Strahlzerleger-Teilbereiche hat, von denen ein zentraler erster Strahlzerleger-Teilbereich topfförmig ausgebildet ist, wobei der zentrale erste Strahlzerleger-Teilbereich mit einem als umlaufender Ringflansch oder Ringabsatz ausgestalteten zweiten Strahlzerleger-Teilbereich verbunden ist, und wobei im zweiten Strahlzerleger-Teilbereich die Zerlegeröffnungen vorgesehen sind.The invention relates to a jet regulator which can optionally be switched between at least two outlet jet images and which has for this purpose a jet regulator housing with at least two housing parts which can be rotated relative to one another, of which an inflow-side first housing part can be rotatably mounted on the water outlet of a sanitary outlet fitting and of which an outflow-side second housing part at least is formed on its outflow-side outer circumference of the housing as a handle or is connected to a handle, the first housing part having a jet splitter with a plurality of splitting openings, with jet channels spaced apart from one another being provided on the housing inner circumference of the second housing part, the individual jets coming from the splitting openings in a first rotational position of the housing parts guided through the jet channels and formed into a circular discharge jet pattern and in a second rotational position in the interior of the jet regulator to form a center len outlet opening of the jet regulator housing are deflected, the jet splitter having two jet splitter sections, of which a central first jet splitter section is cup-shaped, the central first jet splitter section being connected to a second jet splitter section configured as a circumferential ring flange or ring shoulder, and wherein the splitting openings are provided in the second jet splitting section.
Aus der
Die vorbekannte Einsetzeinheit und insbesondere ihr zwischen zwei Auslaufstrahlbildern umschaltbarer Strahlregler sind vergleichsweise aufwendig in der Konstruktion und Herstellung. Darüber hinaus sind die in der vorbekannten Einsetzeinheit erzeugten Auslaufstrahlbilder noch vergleichsweise unsauber und instabil.The previously known insert unit and in particular its jet regulator which can be switched between two discharge jet images are comparatively complex to design and manufacture. In addition, the discharge jet images generated in the known insertion unit are still comparatively unclean and unstable.
Aus der
Es besteht daher insbesondere die Aufgabe, ein Strahlregler der eingangs erwähnten Art zu schaffen, der mit vergleichsweise geringem Aufwand herstellbar ist und der sich durch klar voneinander unterscheidbare sowie in sich stabile Auslaufstrahlbilder auszeichnet.There is therefore in particular the task of creating a jet regulator of the type mentioned at the outset, which can be produced with comparatively little effort and which is distinguished by clearly distinguishable and inherently stable discharge jet images.
Die erfindungsgemäße Lösung dieser Aufgabe sieht dazu vor, dass der topfförmige Strahlzerleger an der Abströmseite seines Topfbodens voneinander beabstandete Stifte oder Zapfen aufweist, welche stiftförmige Strömungshindernisse bilden.The solution to this problem according to the invention provides for the pot-shaped jet splitter to have pins or pegs spaced apart from one another on the outflow side of its pot base, which pins form pin-shaped flow obstacles.
Der Strahlzerleger des erfindungsgemäßen Strahlreglers hatzwei Strahlzerleger-Teilbereiche, von denen ein zentraler erster Strahlzerleger-Teilbereich als topfförmige Beruhigungszone ausgebildet ist, in der das anströmende Wasser abgebremst und über die Umfangswandung dieser Topfform in radialer Richtung zu dem zweiten Strahlzerleger-Teilbereich umgelenkt wird, wobei der zweite Strahlzerleger-Teilbereich als Ringabsatz oder Ringflansch ausgebildet ist, in dem die Zerlegeröffnungen des Strahlzerlegers vorgesehen sind. Erfindungsgemäß ist vorgesehen, dass der topfförmige Strahlzerleger an der Abströmseite seines Topfbodens voneinander beabstandete Stifte oder Zapfen aufweist, welche stiftförmige Strömungshindernisse bilden.The jet splitter of the jet regulator according to the invention has two jet splitter sections, of which a central first jet splitter section is designed as a pot-shaped calming zone, in which the inflowing water is braked and redirected over the peripheral wall of this pot shape in the radial direction to the second jet splitter section, the second jet splitter sub-area is designed as a ring shoulder or ring flange in which the splitting openings of the jet splitter are provided. According to the invention, it is provided that the pot-shaped jet splitter has on the outflow side of its pot base spaced pins or pegs which form pin-shaped flow obstacles.
Da die auf der Abströmseite des Strahlzerlegers vorgesehenen Stifte oder Zapfen stiftförmige Strömungshindernisse bilden, durch die das von den Umlenkschrägen kommende Wasser sich hindurchwinden muss, wird die Geschwindigkeit des Wassers zwischen diesen stiftförmigen Hindernissen wirksam reduziert.Since the pins or pegs provided on the downstream side of the jet splitter form pin-shaped flow obstacles through which the water coming from the deflection bevels has to wind, the speed of the water between these pin-shaped obstacles is effectively reduced.
Damit das durch den erfindungsgemäßen Strahlregler strömende Wasser im Gehäuseinneren des Strahlreglergehäuses in einer der Drehpositionen in den zentralen ersten Strahlregler-Teilbereich geführt werden kann, ist es vorteilhaft, wenn am Innenumfang des zweiten Gehäuseteiles Umlenkschrägen vorgesehen sind, welche die in den Zerlegeröffnungen gebildeten Einzelstrahlen in wenigstens einer zweiten Drehstellung der Gehäuseteile in Richtung zu dem zentralen ersten Strahlregler-Teilbereich umlenken.
Das über die Umlenkschrägen in Richtung zum zentralen ersten Strahlregler-Teilbereich umgelenkte Wasser kommt dort mit einer vergleichsweise hohen Geschwindigkeit an, die nun zunächst reduziert werden muss, bevor das durch den erfindungsgemäßen Strahlregler strömende Wasser in der gewünschten Weise geformt und verändert werden kann. Um das auf der Abströmseite der Umlenkschrägen ankommende Wasser in seiner Geschwindigkeit abzubremsen, ist es zweckmäßig, wenn auf der Abströmseite der Umlenkschrägen voneinander beabstandete stift- oder stegförmige Strömungshindernisse vorgesehen sind.So that the water flowing through the jet regulator according to the invention can be guided in the interior of the jet regulator housing in one of the rotational positions into the central first jet regulator sub-area, it is advantageous if deflecting bevels are provided on the inner circumference of the second housing part, which at least deflect the individual jets formed in the splitter openings deflect a second rotational position of the housing parts in the direction of the central first jet regulator sub-area.
That over the deflection slopes towards the central first Water that is deflected by the jet regulator section arrives there at a comparatively high speed, which now has to be reduced first before the water flowing through the jet regulator according to the invention can be shaped and changed in the desired manner. In order to slow down the speed of the water arriving on the outflow side of the deflection bevels, it is expedient if pin-shaped or web-shaped flow obstacles are provided on the outflow side of the deflection bevels.
Dabei sieht eine bevorzugte Ausführungsform gemäß der Erfindung vor, dass die Stifte oder Zapfen sich zu ihrem abströmseitigen Stift- oder Zapfenende hin vorzugsweise konisch verjüngen und/oder dass das Stift- oder Zapfenende der Stifte oder Zapfen gerundet ist.A preferred embodiment according to the invention provides that the pins or pins preferably taper conically towards their downstream pin or pin end and / or that the pin or pin end of the pins or pins is rounded.
Um die Geschwindigkeit des durch die Stifte oder Zapfen geführten Wassers noch zusätzlich zu reduzieren, ist es vorteilhaft, wenn am Topfboden des topfförmigen Strahlzerlegers abströmseitig ein zentraler Topfboden-Teilbereich vorsteht und/oder wenn der Topfboden des topfförmigen Strahlzerlegers zumindest auf seiner Abströmseite stufenförmig ausgebildet ist.In order to further reduce the speed of the water led through the pins or pegs, it is advantageous if a central pot base portion protrudes on the outflow side of the pot bottom of the pot-shaped jet splitter and / or if the pot bottom of the pot-shaped jet splitter is designed in a step-like manner at least on its outflow side.
Damit der erfindungsgemäße Strahlregler vergleichsweise kompakt ausgebildet werden kann, ist es vorteilhaft, wenn die Stift- oder Zapfenenden der Stifte oder Zapfen etwa in einer Ebene angeordnet sind.
Um das kreisförmig umlaufende Auslaufstrahlbild durch sichtbar getrennt voneinander ausströmende Spraystrahlen zu bilden, ist es vorteilhaft, wenn den Strahlkanälen Spraydüsen in Strömungsrichtung nachgeschaltet sind und wenn die Spraydüsen vorzugsweise in dem auslaufseitigen Teilbereich des Strahlreglergehäuses münden.So that the jet regulator according to the invention can be made comparatively compact, it is advantageous if the pin or pin ends of the pins or pins are arranged approximately in one plane.
In order to form the circular outlet jet pattern by means of spray jets which visibly separate from one another, it is advantageous if spray nozzles are connected downstream of the jet channels in the flow direction and if the spray nozzles preferably open into the outlet region of the jet regulator housing.
Um das im Inneren des Strahlreglers mehr oder weniger aufgewirbelte Wasser zu einem homogen auslaufenden Strahl zu formen, ist es vorteilhaft, wenn zwischen den Strahlkanälen und den Spraydüsen zumindest ein Ringeinsatz vorgesehen ist, der eine als Strömungsgleichrichter dienende Gitter- oder Netzstruktur hat. Damit die Funktion dieser Gitter- oder Netzstruktur als Strömungsgleichrichter noch zusätzlich begünstigt wird, ist es vorteilhaft, wenn die die Gitter- oder Netzöffnungen umgrenzenden Wandabschnitte eine im Vergleich zur Öffnungsweite dieser Gitter- oder Netzöffnungen höhere Längserstreckung in Durchflussrichtung haben.In order to form the more or less swirled water inside the jet regulator into a homogeneously flowing jet, it is advantageous if at least one ring insert is provided between the jet channels and the spray nozzles, which has a grid or network structure serving as a flow straightener. So that the function of this grid or network structure as a flow straightener is additionally favored, it is advantageous if the wall sections surrounding the grid or network openings have a greater longitudinal extent in the flow direction compared to the opening width of these grid or network openings.
Dabei sieht eine besonders vorteilhafte Ausführungsform gemäß der Erfindung vor, dass die Gitterstruktur des Ringeinsatzes durch vorzugsweise radiale Stege gebildet ist, die als Gitteröffnungen Durchflusslöcher zwischen sich begrenzen.A particularly advantageous embodiment according to the invention provides that the lattice structure of the ring insert is formed by preferably radial webs which, as lattice openings, delimit flow holes between them.
Damit die das ringförmig umlaufende Auslaufstrahlbild bildenden Einzelstrahlen ein konisch erweiterndes Auslaufstrahlbild bilden, ist es vorteilhaft, wenn zumindest ein innenliegender Teilbereich der die Spraydüsen umgrenzenden Umfangswandungen schräg nach außen gerichtet ist.In order that the individual jets forming the circular outlet jet image form a conically widening outlet jet image, it is advantageous if at least one inner portion of the peripheral walls surrounding the spray nozzles is directed obliquely outwards.
Ein stabiles und gleichmäßiges Auslaufstrahlbild wird begünstigt, wenn die Zerlegeröffnungen gleichmäßig verteilt über den zweiten Strahlzerleger-Teilbereich angeordnet sind.A stable and uniform discharge jet pattern is favored if the splitting openings are arranged evenly distributed over the second jet splitting sub-area.
Eine besonders gute Abbremswirkung des zum erfindungsgemäßen Strahlregler anströmenden Wassers wird begünstigt, wenn der topfförmige erste Strahlzerleger-Teilbereich lochfrei ausgebildet ist.A particularly good braking effect of the water flowing to the jet regulator according to the invention is favored if the cup-shaped first jet splitter sub-area is designed without holes.
Um den geringen Konstruktions- und Herstellungsaufwand noch zusätzlich zu reduzieren, ist es vorteilhaft, wenn der Strahlzerleger mit dem zuströmseitigen ersten Gehäuseteil einstückig verbunden ist.In order to further reduce the low construction and manufacturing costs, it is advantageous if the jet splitter with the inflow-side first housing part is integrally connected.
Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass das zweite Gehäuseteil zumindest in seinem zuströmseitigen Teilbereich hülsenförmig ausgebildet ist.A preferred embodiment according to the invention provides that the second housing part is sleeve-shaped, at least in its inflow-side section.
Um das erste und das zweite Gehäuseteil des Strahlreglergehäuses auf einfache Weise relativ zueinander verdrehen und dennoch sicher miteinander verbinden zu können, ist es vorteilhaft, wenn das erste und das zweite Gehäuseteil lösbar miteinander verbindbar, vorzugsweise miteinander verrastbar, sind.In order to be able to rotate the first and the second housing part of the jet regulator housing relative to one another in a simple manner and nevertheless securely connect them to one another, it is advantageous if the first and the second housing parts can be detachably connected to one another, preferably locked together.
Eine platzsparende und kompakte Bauweise des erfindungsgemäßen Strahlreglers wird begünstigt, wenn der topfförmige erste Strahlzerleger-Teilbereich des ersten Gehäuseteiles in das Hülseninnere des zweiten Gehäuseteiles vorsteht.A space-saving and compact design of the jet regulator according to the invention is favored if the cup-shaped first jet splitter section of the first housing part protrudes into the sleeve interior of the second housing part.
Durch Verdrehen der beiden Gehäuseteile relativ zueinander werden die Zerlegeröffnungen des im ersten Gehäuseteil vorgesehenen Strahlzerlegers in ihrer Relativposition zu den Kanalöffnungen der im zweiten Gehäuseteil vorgesehenen Strahlkanäle ausgerichtet. Während die Zerlegeröffnungen in einer der ersten Drehstellung entsprechenden Rastposition oberhalb der Kanalöffnungen der Strahlkanäle angeordnet sind, sind diese Zerlegeröffnungen in der zweiten Drehposition der Gehäuseteile auf den zwischen den Strahlkanälen verbleibenden Freiraum oder Längsspalt im Gehäuseinneren des Strahlreglergehäuses ausgerichtet. Dabei kann das durch die zwischen den Strahlkanälen verbleibenden Freiräume geführte Wasser in einen zentralen Abschnitt im Gehäuseinneren des Strahlreglergehäuses umgelenkt werden, um von dort als gegebenenfalls auch belüfteter Gesamtstrahl aus dem Strahlreglergehäuse auszutreten.By rotating the two housing parts relative to one another, the splitting openings of the jet splitter provided in the first housing part are aligned in their position relative to the channel openings of the beam channels provided in the second housing part. While the splitting openings are arranged in a latching position corresponding to the first rotational position above the channel openings of the jet channels, these splitting openings in the second rotating position of the housing parts are aligned with the free space or longitudinal gap between the jet channels in the interior of the jet regulator housing. In this case, the water guided through the free spaces remaining between the jet channels can be deflected into a central section in the interior of the jet regulator housing in order to emerge from there as a possibly also aerated total jet from the jet regulator housing.
Um die jeweils einem Auslaufstrahlbild zugeordneten Strömungswege im Gehäuseinneren des Strahlreglergehäuses voneinander trennen zu können, ohne dass diese Strömungswege gegeneinander abgedichtet werden müssten, ist es vorteilhaft, wenn im zweiten Gehäuseteil eine Innenhülse vorgesehen ist, deren Auslaufstirnseite die zentrale Auslauföffnung bildet.In order to be able to separate the flow paths in the housing interior of the jet regulator housing, each associated with an outlet jet pattern, without these flow paths having to be sealed off from one another, it is advantageous if an inner sleeve is provided in the second housing part, the outlet end of which forms the central outlet opening.
Dabei sieht eine besonders einfache und leicht herstellbare Ausführungsform gemäß der Erfindung vor, dass die Innenhülse in das zweite Gehäuseteil einstückig eingeformt ist.A particularly simple and easy to manufacture embodiment according to the invention provides that the inner sleeve is molded in one piece into the second housing part.
Das durch die Innenhülse geführte Wasser lässt sich gut zu einem homogenen und nicht-spritzenden Gesamtstrahl formen, wenn die die zentrale Auslauföffnung bildende und als Gitter- oder Netzstruktur ausgebildete Auslaufstirnseite der Innenhülse durch sich an Kreuzungsknoten kreuzende und zwischen sich Austrittsöffnungen umgrenzende Stege gebildet ist.The water guided through the inner sleeve can easily be formed into a homogeneous and non-splashing overall jet if the outlet end face of the inner sleeve, which forms the central outlet opening and is designed as a lattice or network structure, is formed by webs which intersect at intersection nodes and which delimit between outlet openings.
Eine bevorzugte Ausführungsform gemäß der Erfindung sieht vor, dass an zumindest einer Umlenkschräge wenigstens ein Strömungsteiler vorgesehen ist, welcher wenigstens eine Strömungsteiler das an der Umlenkschräge entlangströmende Wasser in Teilströme aufteilt. Die in zumindest einer der Umlenkschrägen und vorzugsweise in allen Umlenkschrägen vorgesehenen Strömungsteiler teilen das an ihnen vorbeiströmende Wasser in jeweils mindestens zwei Teilströme auf, die an den in Strömungsrichtung nachfolgenden Strömungshindernissen anschließend weiter zerteilt werden.A preferred embodiment according to the invention provides that at least one flow divider is provided on at least one deflection slope, which at least one flow divider divides the water flowing along the deflection slope into partial flows. The flow dividers provided in at least one of the deflection bevels and preferably in all deflection bevels divide the water flowing past them into at least two partial streams, which are then further divided by the flow obstacles that follow in the flow direction.
Dabei ist es besonders vorteilhaft, wenn der wenigstens eine Strömungsteiler finnenförmig über die zumindest eine Umlenkschräge vorsteht.It is particularly advantageous if the at least one flow divider projects in a fin shape over the at least one deflection slope.
Es kann vorteilhaft sein, wenn die in den Zerlegeröffnungen gebildeten Einzelstrahlen in zumindest einer ersten Drehstellung der Gehäuseteile gegen eine außenliegende Wand der Strahlkanäle geführt sind, und wenn dazu gegenüber der Strahlreglerlängsachse wenigstens eine der Kanalwände der Zerlegeröffnungen und vorzugsweise eine innenliegende Kanalwand der Zerlegeröffnungen schräg nach außen orientiert ist.It may be advantageous if the individual jets formed in the splitter openings are guided in at least a first rotational position of the housing parts against an outer wall of the jet channels, and if for this purpose at least one of the channel walls of the splitter openings and preferably an inner channel wall of the splitter openings obliquely outward relative to the longitudinal axis of the jet regulator is oriented.
Bei diesem Erfindungsvorschlag wird das im Strahlzerleger aufgeteilte und durch die Zerlegeröffnungen geführte Wasser von dort als Einzelstrahlen gegen die außenliegende Kanalwand der Strahlkanäle gerichtet, um von dort zumindest zunächst noch als ringförmig zueinander angeordnete Einzelstrahlen zum Strahlreglerauslauf zu strömen.In this proposal for the invention, the water divided in the jet splitter and guided through the splitter openings is directed from there as individual jets against the outer channel wall of the jet channels in order to flow from there at least initially as individual jets arranged in a ring shape to the jet regulator outlet.
Dabei wird ein sauberes und stabiles Auslaufstrahlbild noch zusätzlich begünstigt, wenn die Strahlkanäle in einem Ringspalt zwischen dem Außenumfang der Innenhülse und dem Gehäuse-Innenumfang des Strahlreglergehäuses angeordnet sind.A clean and stable discharge jet pattern is additionally favored if the jet channels are arranged in an annular gap between the outer circumference of the inner sleeve and the inner circumference of the jet regulator housing.
Damit die aus den Strahlkanälen austretenden Einzelstrahlen noch im Gehäuseinneren ein, eine Ringwand bildendes Auslaufstrahlbild formen können oder damit die Einzelstrahlen als einzelne, ringförmig zueinander angeordnete Spraystrahlen aus dem erfindungsgemäßen Strahlregler austreten, ist es vorteilhaft, wenn die Strahlkanäle in einem auslaufseitigen Teilbereich des Strahlreglergehäuses münden und wenn dieser auslaufseitige Teilbereich einen sich in Auslaufrichtung erweiternden lichten Gehäusequerschnitt hat. Bei dieser Ausführungsform münden die Strahlkanäle noch im Gehäuseinneren des Strahlreglergehäuses in einem auslaufseitigen Teilbereich, wo sie sich beispielsweise zu einer, aus einem dünnen Wasserband geformten Ringwand vereinen können. Da der auslaufseitige Teilbereich einen sich in Auslaufrichtung erweiternden lichten Gehäusequerschnitt hat, spreizt sich diese Ringwand nach dem Austreten aus dem Strahlreglergehäuse noch geringfügig auf, wodurch diese Ringwand noch über eine vergleichsweise lange Wegstrecke des austretenden Wasserstrahls aufrechterhalten bleibt, ohne dass das Wasser zu einem unsauberen und ungeordneten Strahlbild zusammenfällt.So that the individual jets emerging from the jet channels can still form an outlet jet image forming an annular wall inside the housing, or so that the individual jets emerge from the jet regulator according to the invention as individual spray jets arranged in a ring, it is advantageous if the jet channels open into a portion of the jet regulator housing on the outlet side and if this outlet-side section has a clear housing cross-section that widens in the outlet direction. In this embodiment, the jet channels still open in the interior of the jet regulator housing in a partial area on the outlet side, where they can, for example, combine to form an annular wall formed from a thin band of water. Because the outlet side Partial area has a clear housing cross-section widening in the outlet direction, this ring wall still spreads slightly after emerging from the jet regulator housing, whereby this ring wall is maintained over a comparatively long distance of the emerging water jet without the water collapsing into an unclean and disordered jet pattern .
Die Stabilität der einzelnen Spraystrahlen oder der hier aus den Einzelstrahlen gebildeten Ringwand wird auch nach dem Austreten aus dem Strahlreglergehäuse noch über eine vergleichsweise lange Wegstrecke aufrechterhalten, wenn im auslaufseitigen Teilbereich des Strahlreglergehäuses innenumfangsseitig eine Profilierung vorgesehen ist, die durch in Strömungsrichtung orientierte Ein- und Ausformungen gebildet ist. Diese Ein- und Ausformungen am Gehäuseinnenumfang des Strahlreglergehäuses führen dazu, dass die durch das Wasser gebildete Ringwand über eine längere Wegstrecke als konstanter Wasserfilm aufrecht erhalten wird. Damit das am Gehäuseinnenumfang des Strahlreglergehäuses geformte Auslaufstrahlbild besonders sauber aus dem erfindungsgemäßen Strahlregler austreten kann, ist es vorteilhaft, wenn das Strahlreglergehäuse am Innenumfang seines auslaufseitigen Teilbereiches eine Abrisskante aufweist.The stability of the individual spray jets or the annular wall formed here from the individual jets is maintained over a comparatively long distance even after they emerge from the jet regulator housing, if a profile is provided in the outlet-side section of the jet regulator housing on the inside circumference, which is formed by molding and molding oriented in the direction of flow is formed. These indentations and shapes on the inside circumference of the jet regulator housing mean that the ring wall formed by the water is maintained as a constant water film over a longer distance. So that the discharge jet image formed on the inside circumference of the jet regulator housing can emerge from the jet regulator according to the invention in a particularly clean manner, it is advantageous if the jet regulator housing has a tear-off edge on the inner periphery of its outlet-side partial area.
Eine Vergleichmäßigung des Strahlbildes über einen großen Druckbereich wird begünstigt, wenn der Strahlregler Bestandteil einer sanitären Einsetzeinheit ist und wenn dem Strahlregler ein Durchflussmengenregler oder eine Durchflussdrossel vorgeschaltet ist.A uniformization of the jet pattern over a large pressure range is favored if the jet regulator is part of a sanitary application unit and if a flow rate regulator or a flow restrictor is connected upstream of the jet regulator.
Dabei wird eine besonders kompakte und platzsparende Bauweise begünstigt, wenn der Durchflussmengenregler oder die Durchflussdrossel bis zu einem Auflager in das erste Gehäuseteil einsetzbar ist.A particularly compact and space-saving design is favored if the flow rate controller or the flow restrictor can be used up to a support in the first housing part.
Der Durchflussmengenregler oder die Durchflussdrossel kann im Gehäuseinneren des Strahlreglergehäuses und insbesondere des zuströmseitigen ersten Gehäuseteiles gesichert untergebracht werden, wenn dem Durchflussmengenregler oder der Durchflussdrossel ein Vorsatz- oder Filtersieb vorgeschaltet ist, das am ersten Gehäuseteil vorzugsweise lösbar fixierbar ist. Dieses Vorsatz- oder Filtersieb hat die im anströmenden Wasser eventuell enthaltenen Kalk- oder dergleichen Schmutzpartikel auszufiltern, die andernfalls die Funktion der Einsetzeinheit und auch ihres Strahlreglers beeinträchtigen könnten.The flow rate regulator or the flow restrictor can be securely accommodated in the interior of the jet regulator housing and in particular in the inflow-side first housing part if the flow quantity regulator or the flow restrictor is preceded by an attachment or filter screen, which can preferably be detachably fixed to the first housing part. This front screen or filter screen has to filter out the lime or similar dirt particles that may be present in the inflowing water, which could otherwise impair the function of the insert unit and its jet regulator.
Damit sich mit den Änderungen der Drehstellungen auch die jeweiligen Auslaufstrahlbilder verändern lassen, ist es vorteilhaft, wenn zwischen benachbarten Strahlkanälen jeweils eine Umlenkschräge vorgesehen ist.So that the respective discharge jet images can also be changed with the changes in the rotational positions, it is advantageous if a deflection bevel is provided in each case between adjacent jet channels.
Damit das über die Umlenkschrägen umgelenkte Wasser auf der Abströmseite des Strahlzerlegers die dort vorgesehenen stift- oder stegförmigen Strömungshindernisse passieren kann, ist es vorteilhaft, wenn die zumindest eine Umlenkschräge einen Umlenkschrägen-Auslauf hat, der unterhalb dem Strahlzerleger im Hülseninneren des zweiten Gehäuseteiles mündet.So that the water deflected via the deflection bevels on the outflow side of the jet splitter can pass the pin-shaped or web-shaped flow obstacles provided there, it is advantageous if the at least one deflecting bevel has a deflecting bevel outlet which opens below the jet splitter in the sleeve interior of the second housing part.
Um eine zusätzliche Geschwindigkeitsreduktion des im Strahlreglergehäuse umgelenkten Wassers zu erreichen, ist es vorteilhaft, wenn zumindest eine der Umlenkschrägen im Bereich ihres Umlenkschrägen-Auslaufs mindestens einen vorzugsweise flossen- oder finnenartigen Strömungsteiler aufweist.In order to achieve an additional speed reduction of the water deflected in the jet regulator housing, it is advantageous if at least one of the deflection bevels has at least one preferably fin or fin-like flow divider in the region of its deflection bevel outlet.

Um zwischen zwei Auslaufstrahlbildern umschalten zu können, hat der Strahlregler 2, 2' der Einsetzeinheiten 1, 1' mindestens zwei relativ zueinander verdrehbare Gehäuseteile 5, 6; 5', 6'. Während ein zuströmseitiges erstes Gehäuseteil 5, 5' am Wasserauslauf der sanitären Auslaufarmatur drehfest montierbar ist und dazu einen außenumfangsseitigen Ringflansch oder Ringabsatz 29, 29' hat, der zwischen einem innenumfangsseitigen Ringabsatz 30 im Auslaufmundstück 28 und dem abströmseitigen Stirnrand des Wasserauslaufs der sanitären Auslaufarmatur einspannbar ist, ist ein abströmseitiges zweites Gehäuseteil 6, 6' mindestens an seinem abströmseitigen Gehäuseaußenumfang als Handhabe ausgebildet oder mit einer Handhabe verbunden. In
Am Gehäuseinnenumfang des zweiten Gehäuseteiles 6 sind voneinander beabstandete Strahlkanäle 9, 9' vorgesehen, wobei die von den Zerlegeröffnungen 8, 8' kommenden Einzelstrahlen beispielsweise in der in
Um zwischen den Auslaufstrahlbildern wählen und differenzieren zu können, ist zwischen dem ersten und dem zweiten Gehäuseteil 5, 6; 5', 6' eine Drehrasterung vorgesehen. Dazu ist an einer umlaufenden Wandung des ersten Gehäuseteiles 5, 5' eine aus Rasteinformungen 11, 11' und Rastnocken 12, 12' gebildete Rastprofilierung vorgesehen, die mit Rastzähnen 13, 13' zusammenwirkt, welche jeweils an der dem Gehäuseinneren des Strahlreglergehäuses zugewandten Kanalwandung der Strahlkanäle 9, 9' angeformt ist. Die Gehäuseteile 5, 6; 5', 6' lassen sich somit exakt zueinander ausrichten, so dass die zu einem festgelegten Auslaufstrahlbild führenden Strömungswege im Gehäuseinneren des Strahlreglergehäuses exakt eingehalten werden können.In order to be able to choose and differentiate between the outflow jet images, one has to choose between the first and the

Die Rasteinformungen 11, 11' und die Rastvorsprünge oder Rastnocken 12, 12' der Rastprofilierung sind über gerade Rastflanken miteinander verbunden, wobei zwischen jeweils einer Rastflanke und einer Rasteinformung 11, 11' beziehungsweise einer benachbarten Rastnocke 12, 12' eine Profilierungsrundung vorgesehen ist. Um eine satte, jedoch konstruktiv sehr einfach ausgeführte Rasterung zu erreichen, ist die Rastprofilierung in Bezug auf ihre Rasteinformungen 11, 11' und ihre Rastnocken 12, 12' asymmetrisch gestaltet. Während die Rastnocken 12, 12' als ebener Berggipfel ausgebildet sind, dem ein Radius und anschließend wieder eine gerade Flanke folgt, schließt sich daran erneut ein Radius, eine gerade Flanke und anschließend ein zur Rasteinformung führender Radius an, wobei die Rasteinformung 11, 11' hier als durchgehender Radius ausgebildet ist. Um eine saubere Raststellung der Drehrasterung zu erreichen, ist hier vorgesehen, dass die Radien der Profilierungsrundungen und der Rastnocken 13, 13' in etwa übereinstimmen.The latching recesses 11, 11 'and the latching projections or latching

Das durch die Versorgungsleitung und den Armaturenkorpus anströmende Wasser fließt durch das Vorsatz- oder Filtersieb 3, 3' sowie den Durchflussmengenregler 4, 4' hindurch zunächst in den zentral angeordneten topfförmigen Strahlzerleger-Teilbereich 17, 17' und wird dort abgebremst, bevor das Wasser anschließend in Richtung zu den im zweiten Strahlzerleger-Teilbereich 18, 18' vorgesehenen Zerlegeröffnungen 8, 8' umgelenkt wird. Dabei dient der topfförmige Strahlzerleger-Teilbereich 17, 17' als Beruhigungszone für das anströmende Wasser; dieser topfförmige Strahlzerleger-Teilbereich 17, 17' ist lochfrei ausgebildet.The water flowing through the supply line and the valve body flows through the front filter or
Das zweite Gehäuseteil 6, 6' ist zumindest in seinem zuströmseitigen Teilbereich hülsenförmig ausgebildet. Das erste und das zweite Gehäuseteil 5, 6; 5', 6' sind lösbar miteinander verrastbar, wobei das mit dem Strahlzerleger 7, 7' einstückig verbundene erste Gehäuseteil 5 derart in das zweite Gehäuseteil 6, 6' eingesetzt ist, dass der topfförmige erste Strahlzerleger-Teilbereich 17, 17' des ersten Gehäuseteiles 5 in das Hülseninnere des zweiten Gehäuseteiles 6, 6' vorsteht.The
In den Figuren ist besonders gut erkennbar, dass im zweiten Gehäuseteil 6, 6' eine Innenhülse 19, 19' vorgesehen ist, deren Auslaufstirnseite die zentrale Auslauföffnung 10, 10' des Strahlreglergehäuses bildet. Diese Innenhülse 19 ist bei der Einsetzeinheit 1 in das zweite Gehäuseteil 6 einstückig eingeformt. Die die zentrale Auslauföffnung 10, 10' bildende Auslaufstirnseite der Innenhülse 19, 19' ist hier als Gitter- oder Netzstruktur ausgebildet, die durch, sich an Kreuzungsknoten kreuzende und zwischen sich Austrittsöffnungen 20, 20' umgrenzende Stege 21, 21' gebildet ist. Die Stege 21, 21' dieser Gitterstruktur sind hier so angeordnet, dass die Austrittsöffnungen 20, 20' praktisch eine wabenzellenartige Gitterstruktur bilden.In the figures it can be seen particularly well that an

Der Durchflussmengenregler 4 ist bis zu einem Auflager 25, 25' in das erste Gehäuseteil 5 einsetzbar. Da das Vorsatz- oder Filtersieb 3, 3' mit dem ersten Gehäuseteil 5, 5' lösbar verbunden, vorzugsweise lösbar verrastbar ist, ist der dem Vorsatz- oder Filtersieb 3, 3' in Strömungsrichtung nachgeschaltete Durchflussmengenregler 4, 4' im Inneren des ersten Gehäuseteiles 5, 5' im Bereich des Strahlzerlegers 7, 7' platzsparend untergebracht. Der Durchflussmengenregler 4, 4' weist hier zumindest einen Ringspalt 26, 26' auf, in den jeweils ein ringförmiger Drosselkörper 27, 27' aus elastischem Material eingelegt ist. Der zumindest eine Ringspalt 26, 26' hat an seiner innenseitigen und/oder außenseitigen Umfangswandung eine Regelprofilierung, zwischen der und dem elastischen Drosselkörper 27, 27' ein Regelspalt verbleibt, welcher sich unter dem zunehmenden Druck des zuströmenden Wassers derart verengt, dass die pro Zeiteinheit durchströmende Wassermenge auf einen festgelegten Maximalwert eingeregelt ist.The

Der Strahlregler 2' ist ebenfalls zwischen zwei Auslaufstrahlbildern umschaltbar. Um zwischen zwei Auslaufstrahlbildern umschalten zu können, hat auch der Strahlregler 2' zwei relativ zueinander verdrehbare Gehäuseteile 5', 6'. Während das zuströmseitige erste Gehäuseteil 5' mit Hilfe des Teilstücks 32' fest am Wasserauslauf gehalten ist, ist das abströmseitige zweite Gehäuseteil 6' mit dem als Handhabe dienenden Teilstück 33' des Auslaufmundstücks 28' derart drehfest verbunden, dass das zweite Gehäuseteil 6' relativ zum ersten Gehäuseteil 5' gedreht werden kann.The jet regulator 2 'can also be switched between two discharge jet images. In order to be able to switch between two discharge jet images, the jet regulator 2 'also has two housing parts 5', 6 'which can be rotated relative to one another. While the inflow-side first housing part 5 'is held firmly at the water outlet with the aid of the section 32', the outflow-side second housing part 6 'is rotatably connected to the section 33' of the outlet mouthpiece 28 'serving as a handle such that the second housing part 6' relative to the first housing part 5 'can be rotated.
Am Gehäuseinnenumfang des zweiten Gehäuseteiles 6' sind in Umfangsrichtung voneinander vorzugsweise gleichmäßig beabstandete Stahlkanäle 9' vorgesehen, welche die von den Zerlegeröffnungen 8' des Strahlzerlegers 7' kommenden Einzelstrahlen einfangen. Das zweite Gehäuseteil 6' ist hier aus zwei separaten Teilen gebildet, von denen die Innenhülse 19' in eine Außenhülse 42' eingesetzt ist. Die aus den Zerlegeröffnungen 8' kommenden Einzelstrahlen werden in der einen, ersten Drehstellung der Gehäuseteile 5', 6' zwischen der Innenhülse 19' und der Außenhülse 42' des zweiten Gehäuseteiles 6' weitergeführt, bevor sie abströmseitig angeordnete Spraydüsen 35' erreichen, welche in dem auslaufseitigen Teilbereich des Strahlreglergehäuses münden. In dem zwischen den Strahlkanälen 9' und den Spraydüsen 35' befindlichen Ringraum weist der Strahlregler 2' zumindest einen Ringeinsatz 36' auf, der eine Gitter- oder Netzstruktur hat und der als ein das durchströmende Wasser vergleichmäßigender Strömungsgleichrichter dienen soll. Diese Gitterstruktur ist bei dem hier verwendeten Ringeinsatz 36' durch radiale Stege gebildet, die Durchflusslöcher zwischen sich begrenzen. Da zumindest der innenliegende Teilbereich der die Spraydüsen 35' umgrenzenden Umfangswandungen schräg nach außen gerichtet ist, werden die aus den Spraydüsen 35' sichtbar separat austretenden Einzelstrahlen schräg nach außen abgelenkt, so dass ein aus auseinanderströmenden Einzelstrahlen gebildetes, ringförmig umlaufendes Auslaufstrahlbild entsteht.
In der demgegenüber zweiten Drehstellung der Gehäuseteile 5', 6' werden die aus den Zerlegeröffnungen 8' austretenden Einzelstrahlen jeweils über eine Umlenkschräge 37' geführt, welche die in den Zerlegeröffnungen 8' gebildeten Einzelstrahlen in dieser zweiten Drehstellung in Richtung zur zentralen Auslauföffnung 10' radial nach innen umlenken. Dabei ist zwischen benachbarten Strahlkanälen 9' jeweils eine der Umlenkschrägen 37' vorgesehen. In den Umlenkschrägen 37' ist jeweils ein flossen- oder finnenförmiger Strömungsteiler 44' vorgesehen, der bereits eine erste Aufteilung des zuströmenden Wassers bewirkt. Durch die finnenförmigen Strömungsteiler 44' wird das an den Umlenkschrägen 37' radial nach innen umgelenkte Wasser jeweils in zumindest zwei Teilströme aufgeteilt, wobei die derart radial nach innen umgelenkten Teilströme jeweils wiederum auf die an der Abströmseite des Strahlzerlegers 7' vorstehenden Stifte 38' auftreffen und dort erneut derart aufgeteilt werden, dass eine besonders gute Durchmischung des durch den Strahlregler 1' durchströmenden Wassers mit der Umgebungsluft erfolgt. Das derart mit Umgebungsluft durchmische Wasser kann anschließend über die zentrale Auslauföffnung 10' aus dem Strahlregler 2' als belüfteter Wasserstrahl austreten.On the inner circumference of the second housing part 6 ', steel channels 9' are provided which are preferably evenly spaced apart from one another in the circumferential direction and which capture the individual jets coming from the splitting openings 8 'of the jet splitter 7'. The second housing part 6 'is formed here from two separate parts, of which the inner sleeve 19' is inserted into an
In contrast, in the second rotational position of the housing parts 5 ', 6', the individual jets emerging from the splitter openings 8 'are each guided over a deflection bevel 37' which, in this second rotational position, directs the individual jets formed in the splitter openings 8 'radially towards the central outlet opening 10' redirect inwards. One of the deflection slopes 37 'is provided between adjacent beam channels 9'. A fin or fin-shaped flow divider 44 'is provided in each of the deflection bevels 37', which already causes a first division of the inflowing water. The fin-shaped flow dividers 44 'divide the water diverted radially inwards at the deflection slopes 37' into at least two partial streams, the partial streams diverted radially inwards in this way in each case striking the pins 38 'projecting on the outflow side of the jet splitter 7' and there are divided again in such a way that the water flowing through the jet regulator 1 ′ is mixed particularly well with the ambient air. The water mixed with ambient air in this way can then emerge from the jet regulator 2 'as a aerated water jet via the central outlet opening 10'.
