Description

Die Erfindung betrifft eine sanitäre Einsetzeinheit mit einem Strahlregler, mit einem dem Strahlregler zuströmseitig vorgeschalteten Vorsatzsieb und mit einem zwischen Strahlregler und Vorsatzsieb vorgesehenen Durchflussmengenregler, der einen Drosselkörper aus elastischem Material hat, welcher zwischen sich und einer, an einer Umfangswandung vorgesehenen Regelprofilierung einen sich unter dem Druck des durchströmenden Wassers verändernden Steuerspalt umgrenzt, wobei der Durchflussmengenregler an dem Strahlregler und das Vorsatzsieb an dem Durchflussmengenregler lösbar gehalten ist.The invention relates to a sanitary inserting unit with a jet regulator, with a front screen arranged upstream of the jet regulator and with a flow regulator provided between jet regulator and front screen, which has a throttle body made of elastic material, which under itself and a rule profiling provided on a circumferential wall extends below the Pressure of the water flowing through the control gap bounded, wherein the flow regulator on the jet regulator and the front screen on the flow regulator is releasably held.

Aus der EP 0 733 148 A1 der Anmelderin ist bereits eine sanitäre Einsetzeinheit vorbekannt, die einen Strahlregler, ein zuströmseitig vorgeschaltetes Vorsatzsieb sowie einen zwischen Strahlregler und Vorsatzsieb angeordneten Durchflussmengenregler aufweist. Während der Strahlregler einen homogenen und nicht-spritzenden Wasserstrahl formen soll, ist das Vorsatzsieb dazu bestimmt, die im durchströmenden Wasser eventuell mitgeführten Schmutzpartikel zurückzuhalten. Der zwischengeschaltete Durchflussmengenregler hat das pro Zeiteinheit durchströmende Wasservolumen unabhängig vom Wasserdruck auf einen festgelegten Maximalwert einzuregeln und zu begrenzen. Der Durchflussmengenregler weist dazu einen ringförmigen Drosselkörper aus elastischem Material auf, der zwischen sich und einer, an einer Umfangswandung vorgesehenen Regelprofilierung einen sich unter dem Druck des durchströmenden Wassers verändernden Steuerspalt umgrenzt. Der Durchflussmengenregler, das Vorsatzsieb und der Strahlregler der vorbekannten Einsetzeinheit weisen an ihren einander zugewandten Enden jeweils zueinander passende Anschlussmittel auf, die ein lösbares Verbinden dieser Einbauteile gewährleisten. Auf diese Weise ist es möglich, den Strahlregler der vorbekannten Einsetzeinheit gegebenenfalls auch willkürlich oder versehentlich allein mit dem Durchflussmengenregler oder allein mit dem Vorsatzsieb zu verwenden. Wird der Strahlregler aber allein mit dem Durchflussmengenregler verwendet, besteht u.a. die Gefahr, dass im Wasserstrom eventuell mitgeführte Schmutzpartikel in den Mengenregler gelangen und dort zu Fehlleistungen und insbesondere zu geringeren Literleistungen des Durchflussmengenreglers führen. Durch derart beliebige Zusammenstellungen der Einbauteile besteht die Gefahr, dass die vorbekannte Einsetzeinheit die ihr zugedachte Funktion nicht oder nicht optimal erfüllen kann.From the EP 0 733 148 A1 the Applicant is already a sanitary inserting unit previously known, which has a jet regulator, a front side upstream filter screen and a arranged between the jet regulator and front screen flow regulator. While the jet regulator is to form a homogeneous and non-squirting jet of water, the header screen is intended to retain the particles of dirt that might be carried along in the water flowing through. The intermediate flow regulator must regulate the volume of water flowing through per unit time regardless of the water pressure to a set maximum value limit. For this purpose, the flow rate regulator has an annular throttle body made of elastic material, which delimits between itself and a control profile provided on a circumferential wall a control gap which changes under the pressure of the water flowing through. The flow rate regulator, the front screen and the jet regulator of the previously known insertion unit have at their mutually facing ends in each case mating connection means which ensure a releasable connection of these built-in parts. In this way, it is possible, if appropriate, to use the jet regulator of the previously known insertion unit either alone or inadvertently with the flow rate regulator alone or with the attachment sieve. However, if the jet regulator is used alone with the flow rate regulator, there is the risk, inter alia, that dirt particles entrained in the water flow may enter the flow regulator and lead there to erroneous performance and, in particular, lower liter rates of the flow rate regulator. By such arbitrary compilations of the mounting parts there is a risk that the previously known insertion unit can not fulfill its intended function or not optimal.

Es besteht daher insbesondere die Aufgabe, eine sanitäre Einsetzeinheit der eingangs erwähnten Art zu schaffen, die trotz ihrer Vielteiligkeit stets in einer Zusammenstellung ihrer Einbauteile gehalten wird, welche eine optimale Funktion der erfindungsgemäßen Einsetzeinheit sicherstellt.There is therefore a particular object to provide a sanitary inserting unit of the type mentioned, which is always maintained in spite of their many parts in a compilation of their built-in parts, which ensures optimum function of the insertion unit according to the invention.

Die erfindungsgemäße Lösung dieser Aufgabe besteht bei der sanitären Einsetzeinheit der eingangs erwähnten Art insbesondere darin, dass die Regelprofilierung an mindestens einer Umfangswandung eines Regelkörpers vorgesehen ist, dass der Regelkörper über wenigstens einen Verbindungssteg mit einer Halterung verbunden ist, dass der wenigstens eine Verbindungssteg als Niederhalter für den, zwischen dem wenigstens einen Verbindungssteg und dem Strahlregler angeordneten Drosselkörper vorgesehen ist, und dass die Halterung mit ihrem zuströmseitigen Stirnrandbereich am Vorsatzsieb und mit ihrem abströmseitigen Stirnrandbereich am Innenumfang des Reglergehäuses lösbar befestigbar ist.The achievement of this object is in the sanitary inserting unit of the type mentioned in particular that the rule profiling is provided on at least one peripheral wall of a control body, that the control body is connected via at least one connecting web with a holder that the at least one connecting web is provided as a hold-down for the arranged between the at least one connecting web and the jet regulator throttle body, and that the holder with its inflow-side end edge region on the attachment screen and with its downstream end edge region on the inner circumference of the regulator housing is detachably fastened.

Bei der erfindungsgemäßen Einsetzeinheit ist die Regelprofilierung an einer inneren und/oder äußeren Umfangswandung eines Regelkörpers vorgesehen. Dieser Regelkörper ist über wenigstens einen Verbindungssteg mit einer Halterung verbunden, die mit ihrem zuströmseitigen Stirnrandbereich am Vorsatzsieb und mit ihrem abströmseitigen Stirnrandbereich am Innenumfang des Reglergehäuses lösbar befestigt ist. Dabei ist der wenigstens eine, die zumindest eine Halterung mit dem Regelkörper verbindende Verbindungssteg als Niederhalter ausgebildet, welcher den Drosselkörper im Bereich zwischen dem Strahlregler einerseits und dem wenigstens einen Verbindungssteg andererseits hält. Da die Halterung das Vorsatzsieb mit dem Durchflussmengenregler verbindet, stellt die mit dem Regelkörper verbundene Halterung eine Art von Originalitätssicherung dar, derart, dass das Vorsatzsieb und der Strahlregler nur dann zusammengehalten werden, wenn auch der Durchflussmengenregler montiert ist. Wird beispielsweise bei der Montage der erfindungsgemäßen Einsetzeinheit der Durchflussmengenregler vergessen, dann kann auch das Vorsatzsieb nicht montiert werden und der Fehler ist sofort erkennbar.In the inserting unit according to the invention, the control profiling is provided on an inner and / or outer circumferential wall of a control body. This control body is connected via at least one connecting web with a holder which is releasably secured with its inflow-side end edge region on the attachment screen and with its downstream end edge region on the inner circumference of the regulator housing. Here, the at least one connecting the at least one support with the control body connecting web is designed as a hold-down, which holds the throttle body in the region between the jet regulator on the one hand and the at least one connecting web on the other. Because the bracket connects the header screen to the flow regulator, the bracket connected to the regulator body provides some form of tamper evidence such that the header and jet regulators are only held together when the flow regulator is mounted. If, for example, the flow rate regulator is forgotten during assembly of the insertion unit according to the invention, then the attachment screen can not be mounted and the error can be recognized immediately.

Um die Einbauteile der erfindungsgemäßen Einsetzeinheit dauerhaft und dennoch leicht lösbar miteinander verbinden zu können und um die Einbaulänge der erfindungsgemäßen Einsetzeinheit möglichst gering zu halten, ist es vorteilhaft, wenn der Durchflussmengenregler ein Reglergehäuse hat, das mit seinem abströmseitigen Stirnendbereich in einer Einsetzöffnung am Strahlregler einsetzbar ist.In order to permanently and easily detachably connect the mounting parts of the insertion unit according to the invention and to keep the installation length of the insertion unit according to the invention as low as possible, it is advantageous if the flow rate regulator has a regulator housing, with its downstream Stirnendbereich in an insertion can be used on the jet regulator.

Eine genaue Festlegung der zwischen den Einbauteilen der erfindungsgemäßen Einsetzeinheit vorgesehenen Position wird begünstigt, wenn der Strahlregler einen Ringabsatz hat, der den Einsetzweg des Reglergehäuses in die Einsetzöffnung begrenzt.A precise determination of the intended between the mounting parts of the insertion unit according to the invention position is favored when the jet regulator has an annular shoulder which limits the insertion of the regulator housing in the insertion.

Eine bevorzugte Weiterbildung gemäß der Erfindung sieht vor, dass am Außenumfang des Reglergehäuses ein Ringflansch vorgesehen ist, mit dem das Reglergehäuse in die Einsetzöffnung einsetzbar ist. Bei dieser Ausführungsform weist der Durchflussmengenregler im Vergleich zum Strahlregler einen, um den Ringflansch reduzierten Außendurchmesser auf, so dass sich die erfindungsgemäße Einsetzeinheit auch in den eventuell geringen lichten Durchflussquerschnitt am Auslaufende einer sanitären Auslaufarmatur einsetzen lässt.A preferred development according to the invention provides that an annular flange is provided on the outer circumference of the regulator housing, with which the regulator housing can be inserted into the insertion opening. In this embodiment, the flow regulator in comparison to the jet regulator, an outer diameter reduced around the annular flange, so that the insertion unit according to the invention can also be used in the possibly small clear flow cross section at the outlet end of a sanitary outlet fitting.

Auf der Zuströmseite des Durchflussmengenreglers wird der Drosselkörper in axialer Richtung durch den wenigstens einen, als Niederhalter dienenden Verbindungssteg gesichert. Um eine solche axiale Sicherung auch auf der Abströmseite zu gewährleisten, ist es vorteilhaft, wenn am Innenumfang des Reglergehäuses ein Ringflansch vorgesehen ist, auf dem der Drosselkörper in Gebrauchsstellung aufliegt. Der derart beidseits in axialer Richtung gesicherte Drosselkörper wird somit genau in der gewünschten Position im Bereich der Regelprofilierung gehalten.On the upstream side of the flow regulator, the throttle body is secured in the axial direction by the at least one, serving as hold-down connecting web. In order to ensure such axial securing on the downstream side, it is advantageous if an annular flange is provided on the inner circumference of the regulator housing, on which rests the throttle body in the use position. The thus secured on both sides in the axial direction throttle body is thus kept exactly in the desired position in the range of the control profile.

Eine besonders leicht herstellbare Ausführungsform gemäß der Erfindung sieht vor, dass die wenigstens eine Halterung am Vorsatzsieb und/oder am Reglergehäuse lösbar verrastbar ist.A particularly easy to manufacture embodiment according to the invention provides that the at least one holder on the attachment screen and / or on the controller housing is releasably latched.

Möglich ist, dass an den Regelkern mehrere Halterungen angeformt sind, die am Vorsatzsieb und/oder am Reglergehäuse an mehreren, voneinander beabstandeten Befestigungsstellen angreifen. Bevorzugt wird jedoch eine Ausführungsform gemäß der Erfindung, bei welcher die Halterung als Haltering ausgestaltet ist.It is possible that a plurality of brackets are formed on the control core, on the front screen and / or on the controller housing attack a plurality of spaced apart attachment points. However, an embodiment according to the invention in which the holder is designed as a retaining ring is preferred.

Vorteilhaft ist es, wenn an der Halterung zumindest ein Rastvorsprung, eine Rastausnehmung oder dergleichen Rastmittel vorgesehen ist, welches Rastmittel mit einem Gegenrastmittel am Vorsatzsieb und/oder am Reglergehäuse zusammenwirkt.It is advantageous if at least one latching projection, a latching recess or the like locking means is provided on the holder, which latching means cooperates with a counter-latching means on the attachment screen and / or on the controller housing.

Besonders vorteilhaft ist es, wenn der Strahlregler einen Strahlzerleger hat, der topfförmig ausgestaltet ist und der an der Umfangswandung seiner Topfform eine Mehrzahl vorzugsweise gleichmäßig voneinander beabstandeter und das durchströmende Wasser in eine Mehrzahl von Einzelstrahlen aufteilender Durchflussöffnungen hat.It is particularly advantageous if the jet regulator has a jet disintegrator which is pot-shaped and which has a plurality of preferably uniformly spaced apart and at the peripheral wall of its pot shape flow through the water into a plurality of single-jet flow openings.

Weitere Merkmale gemäß der Erfindung ergeben sich aus der nachfolgenden Figurenbeschreibung in Verbindung mit den Ansprüchen sowie der Zeichnung. Nachstehend wird die Erfindung anhand eines bevorzugten Ausführungsbeispieles noch näher beschrieben.Further features according to the invention will become apparent from the following description of the figures in conjunction with the claims and the drawings.

Die Einsetzeinheit 1 weist einen Strahlregler 2 auf, der einen homogenen, nicht-spritzenden und gegebenenfalls auch perlend-weichen Wasserstrahl formen soll. Dem Strahlregler 2 ist zuströmseitig ein Vorsatzsieb 3 vorgeschaltet, dass die im Wasser eventuell mitgeführten Schmutzpartikel, welche die Funktion der nachfolgenden Funktionseinheiten beeinträchtigen könnten, zurückzuhalten hat. Zwischen dem Strahlregler 2 und dem Vorsatzsieb 3 ist ein Durchflussmengenregler 4 vorgesehen, der das durchströmende Wasservolumen unabhängig vom Wasserdruck auf einen festgelegten Maximalwert begrenzen und einregeln soll.In the single FIGURE, a sanitary inserting unit 1 is shown, which can be mounted at the outlet end of a sanitary outlet fitting by means of an outlet nozzle (not further shown). The insertion unit 1 has a jet regulator 2, which is to form a homogeneous, non-splashing and possibly also pearly-soft water jet. The jet regulator 2 upstream of a front screen 3 is preceded that the possibly entrained in the water Dirt particles, which could affect the function of the following functional units, has to retain. Between the jet regulator 2 and the front screen 3, a flow rate regulator 4 is provided which is intended to limit and regulate the water volume flowing through, irrespective of the water pressure, to a defined maximum value.

Der Durchflussmengenregler 4 weist ein hülsenförmiges Reglergehäuse 5 auf, in dessen Gehäuseinnenraum ein ringförmiger Drosselkörper 6 aus elastischem Material vorgesehen ist. Der Drosselkörper 6 umgrenzt zwischen sich und einer, an einer Umfangswandung vorgesehenen Regelprofilierung 7 einen Steuerspalt 8, der sich unter dem Druck des durchströmenden Wassers verwendet. Dabei wird der Drosselkörper 6 bei steigendem Wasserdruck zunehmend in die Ausnehmungen 9 der Regelprofilierung 7 gepresst, derart, dass sich der Steuerspalt 8 verengt und einen in Abhängigkeit vom Wasserdruck kleineren Durchflussquerschnitt freihält.The flow rate regulator 4 has a sleeve-shaped regulator housing 5, in the housing interior of which an annular throttle body 6 made of elastic material is provided. The throttle body 6 defines between itself and a, provided on a peripheral wall rule profiling 7 a control gap 8, which is used under the pressure of the water flowing through. In this case, the throttle body 6 is increasingly pressed with increasing water pressure in the recesses 9 of the control profile 7, such that the control gap 8 narrows and a smaller depending on the water pressure flow cross section.

Der Durchflussmengenregler 4 ist an dem Strahlregler 2 und das Vorsatzsieb 3 ist am Durchflussmengenregler 4 lösbar gehalten.The flow rate regulator 4 is held on the jet regulator 2 and the attachment sieve 3 is detachably held on the flow rate regulator 4.

Die Regelprofilierung 7, die in Durchströmrichtung orientierte und über den Umfang verteilte Ausnehmungen 9 oder Rillen hat, ist an der inneren und/oder äußeren Umfangswandung eines Regelkörpers 11 angeordnet, der hier als ein im Inneren des Reglergehäuses 5 vorgesehener zentraler Regelkern 11 ausgebildet ist. Der Regelkern 11 ist über wenigstens einen, quer zur Durchströmrichtung orientierten Verbindungssteg 12 mit einer Halterung 13 verbunden, die hier als Haltering ausgestaltet ist.
