Definitions
- the invention relates to a device for conditioning rinsing liquid in sanitary Facilities by placing a subset of each in a pan in each flush stored liquid conditioning substance is entered into the rinsing liquid, according to the preamble of claim 1.
- the conditioning substance can be disinfectant and / or air-improving and / or cleaning and / or coloring liquid active ingredients act as they are on the market Are available.
- Known devices of the generic type include those in which the Conditioning substance over a soakable, permanent or with the rinsing liquid Intermittent element, e.g. added from an open-cell foam and those where the addition is based on a siphon effect.
- Conditioning devices of the first type mentioned are e.g. in EP-B-0 538 957 or EP-A-785315 described.
- the capillary pathways that contain the conditioning substance from a Storage vessel must cover up to the pending rinsing liquid, what are relatively long can easily render the device unusable by clogging the capillary paths can. Another consequence of this is that the amount dosed in the rinsing liquid Conditioning substance may initially be set too high, which if necessary with a undesirable environmental pollution.
- conditioning devices e.g. are known from DE-A-2916385, mainly conditioning substances in solid form can and is used it is hardly possible to dispense the conditioning substance evenly with each rinse guaranteed.
- a conditioning device (DE-A-19520145), the one contains a filling space of the device filling substance of pasty consistency. The Flushing liquid is passed over the surface of the filling with each flushing process in order to entrain a small amount of the pasty substance. It is not just measures against unwanted sump formation is also necessary Adjust the viscosities of the substances reacting with each other to make a to get approximately uniform release of active ingredient.
- Fluctuations in the strength of the Flushing liquid flow as can occur for a variety of reasons, also have one uneven, possibly interrupted release of conditioning substance, so that it is not guaranteed that the metered amount of conditioning substance from the rinsing process for rinsing is always the same.
- the invention has for its object a structurally simple design To provide a conditioning device for dispensing liquid conditioning substances, which with every rinsing process a uniform, time-controlled release of active ingredient in the Irrigation liquid guaranteed regardless of the strength of the prevailing rinsing flow.
- the Amount of conditioning substance added to the rinsing liquid with each rinsing process can be precisely specified by an outlet opening of a pantry for the Conditioning substance with each rinsing process specifically over a period of time during which a Collecting container for the rinsing liquid is filled, opened and at the end of the rinsing process Elapse of one of the passage capacity of an emptying opening of the collecting vessel is locked again at a certain time.
- For triggering a substance delivery is not that Strength or duration of the respective rinsing liquid flow, but the filling of the Decisive receptacle. The e.g.
- the amount of conditioning substance released can be finer according to one Further development of the invention can be further evened out in that it is the volume a space not occupied by the sealing element inside a prechamber corresponds to the pantry, which in the closed position of the sealing element with the Conditioning substance is filled and emptied in the release position. A swamp formation is avoided in the device since no liquid remains after a rinsing process.
- the device allows easy refilling with liquid conditioning substance. It is therefore characterized by a particularly favorable usability and also by a simple inexpensive manufacturing option.
- the conditioning device according to the invention is composed of one in FIG. 2 with the general reference number 1 indicated base or lower part and one with the general reference number 2 indicated upper or lid part, which by the circumference Both parts provided, engageable locking means 3 releasably together can be connected.
- a bracket 4 for clamping the device can be attached to the cover part 2 an edge of a toilet bowl or the like.
- the base part 1 and cover part 2 are preferably molded parts made of a suitable plastic material, such as a polyolefin. Other materials can also be used.
- the base part 1 defines a storage chamber 5 for receiving an amount Conditioning substance, which via a filling opening 6 in the lid part 2, cf. Fig. 2, in the Storage chamber 5 can be filled without the cover part 2 having to be lifted off.
- a suitable, e.g. central point of the underside of the bottom wall 7 of the base part 1 protrudes circumferentially of an opening 10 made in the bottom wall 7, a sealing flange-like extension 8 that creates an unspecified antechamber.
- the opening 10 forms an inlet in the antechamber or a connection between it and the pantry 5.
- the lower free end region of the extension 8 is curved inward like a sealing lip and forms on the inside of the neck 8 a first or lower annular sealing surface 9 with which a Approach 8 recorded spherical sealing element 11 engage in sealing engagement can to an outlet opening 12 delimited by the annular sealing surface 9 To close the antechamber.
- the sealing element 11 is freely movable in the antechamber added and can with a second or upper annular sealing surface 13 which the Inlet or surrounds the opening 10 in sealing engagement to the opening 10 to close when the sealing element 11 under a force from the sealing engagement with the lower sealing surface 9 has been moved out, which is generally indicated by 14 in FIG indicated actuating element can be exerted on the sealing element 11.
- the sealing member 11 becomes in the sealing relationship shown in Figs Sealing surface 9 along the outlet opening 12 due to its own weight and the Sealing element 11 acting gradient pressure in the storage chamber 5 Amount of conditioning substance kept.
- Fig. 2 shows the structure of the actuating element 14.
- the actuating element 14 is basically in the manner of a rocker with an arm region that can be pivoted about an axis of rotation 15 16 on one side of the axis of rotation 15 (on the right in FIG. 2) and an arm region in the form of a Collection vessel 19 formed on the other side (left side) of the axis of rotation 15.
- the axis of rotation 15 can, as Fig. 1 shows, between opposite wall sections of a secondary chamber 18 forming pocket-shaped projection 17 of the conditioning device, which is provided on the outside of the storage chamber 5 on the base part 1, as shown in FIG. 2.
- the secondary chamber 18 is open at the top, so that part of a rinsing liquid in one from the rinsing liquid stream falling above the conditioning device, cf. arrows Sp in Fig. 3, in the sub-chamber 18 can get into each flushing to Fill the receptacle 19 of the actuating element 14.
- the left-hand region of the actuator 14 exerts a downward force that the right arm portion 16 moves up to the sealing member 11 from the sealing engagement with the first or lower sealing surface 9 and in sealing engagement to move with the upper or second sealing surface 13 of the neck 8.
- the opening 10 will consequently closed during each rinsing process and the outlet opening 12 of the attachment 8 Approved. Under these circumstances, the free space between the sealing element 11 and the interior of the approach 8 existing conditioning substance via the outlet opening 12 step outside and mix with the flushing liquid flow, cf. Arrows K in Fig. Third
- the collecting vessel 19 is constantly emptied a throttle bore 20 takes place at a lower area in the wall of the collecting vessel 19th is provided so that when a rinsing process ends in the receptacle 19 remaining Flushing liquid is gradually discharged to the outside and thereby onto the sealing element 11 exerted force is released. As a result, the sealing member 11 comes after each Flushing process back into the relationship sealing the outlet opening 12.
- the force exerted on the actuating element 14 during a flushing process is made up of a dynamic component in the form of the flow force of the rinsing liquid when this in the Secondary chamber 18 strikes the collecting vessel 19, and the weight of the in the collecting vessel 19th retained rinsing liquid together.
- the force is therefore high enough to do that Sealing element 11 against the biasing force from its own weight and the gradient pressure of the conditioning substance stored in the storage chamber 5 from the closing to the To move release position.
- the amount dispensed during each flushing process of conditioning substance to be precisely specified.
- the quantity delivered is not depending on the length of time during which the sealing element 11 is in the release position located.
- the sealing element in its release position the inlet into Keeps the interior of the antechamber closed, it is understood that such an accurate Dosage of the amount of conditioning substance dispensed with each rinsing process enabling function also omitted and instead a permanent fluid connection could be provided between the pantry and the prechamber.
- Actuator can also be designed without a collecting vessel, so that with each Force acting on the flushing process essentially through the dynamic flow force components is determined.
- the sealing element does not necessarily need a spherical one Have configuration. Rather, another one, e.g. cylindrical or frustoconical configuration can be provided.
- the sealing element could also on Arm area of the actuator to be articulated.
- the sealing element is biased into its closed position by a spring or the like.

Description
Die Erfindung betrifft eine Vorrichtung zur Konditionierung von Spülflüssigkeit bei sanitären
Einrichtungen, indem bei jedem Spülvorgang eine Teilmenge einer in einer Vorratskammer
gespeicherten flüssigen Konditionierungssubstanz in die Spülflüssigkeit eingegeben wird,
gemäss dem Oberbegriff des Patentanspruches 1.The invention relates to a device for conditioning rinsing liquid in sanitary
Facilities by placing a subset of each in a pan in each flush
stored liquid conditioning substance is entered into the rinsing liquid,
according to the preamble of
Bei der Konditionierungssubstanz kann es sich um desinfizierende und/oder luftverbesserende und/oder reinigende und/oder färbende flüssige Wirkstoffe handeln, wie sie auf dem Mark verfügbar sind.The conditioning substance can be disinfectant and / or air-improving and / or cleaning and / or coloring liquid active ingredients act as they are on the market Are available.
Bekannte Vorrichtungen der gattungsgemässen Art umfassen solche, bei denen die Konditionierungssubstanz über ein damit tränkbares, mit der Spülflüssigkeit permanent oder intervallmässig beaufschlagbares Element, z.B. aus einem offenporigen Schaumstoff zugegeben wird, und solche, bei denen die Zugabe auf einem Siphoneffekt beruht. Konditionierungsvorrichtungen der erst genannten Art sind z.B. in der EP-B-0 538 957 oder EP-A-785315 beschrieben. Die Kapillarwege, die die Konditionierungssubstanz von einem Vorratsgefässes bis zur anstehenden Spülflüssigkeit zurücklegen muss, sind relativ lang, was leicht zu einem Unbrauchbarwerden der Vorrichtung durch Verstopfen der Kapillarwege führen kann. Eine weitere Folge davon ist, dass die in der Spülflüssigkeit dosierte Menge an Konditionierungssubstanz anfänglich zu hoch eingestellt sein kann, was ggf. mit einer unerwünschten Belastung der Umwelt verbunden sein kann. Bei auf dem Siphoneffekt beruhenden Konditionierungsvorrichtungen, wie sie z.B. aus der DE-A-2916385 bekannt sind, können vornehmlich nur Konditionierungssubstanzen in fester Form verwendet werden und ist eine gleichmässige dosierte Abgabe der Konditionierungssubstanz bei jedem Spülvorgang kaum gewährleistet. Bekannt ist auch eine Konditionierungsvorrichtung (DE-A-19520145), die eine einen Füllraum der Vorrichtung füllende Substanz von pastenförmiger Konsistenz enthält. Die Spülflüssigkeit wird bei jedem Spülvorgang über die Oberfläche der Füllung geleitet, um dabei eine geringe Menge der pastenförmigen Substanz mitzureissen. Es sind nicht nur Massnahmen gegen eine unerwünschte Sumpfbildung erforderlich, ausserdem ist auch eine gezielte Abstimmung der Viskositäten der miteinander reagierenden Substanzen vorzunehmen, um eine annähernd gleichmässige Wirkstoffabgabe zu erhalten. Schliesslich ist eine Konditionierungsvorrichtung (DE-A-2532963) bekannt, bei der bei einem Spülvorgang ein Strom der Spülflüssigkeit auf eine um eine Achse schwenkbare Prallplatte trifft, wobei die dynamische Kraft des Spülflüssigkeitsstromes eine Drehung der Prallplatte bewirkt, welche Bewegung ausgenutzt wird, um ein kugelförmiges Dichtungselement aus dem dichtenden Eingriff mit einer Auslassöffnung eines Vorratsbehälters für eine flüssige Konditionierungssubstanz zu bringen. Dadurch ist die konditionierende Wirkung der bekannten Konditionierungsvorrichtung auf die kurze Zeit beschränkt, bei der ein Spülflüssigkeitsstrom mit ausreichender Strömungsenergie die Prallplatte beaufschlagt. Desinfizierende oder luftverbessernde Wirkungen können daher, wenn überhaupt, nur sehr kurzzeitig erreicht werden. Eine grundsätzlich erwünschte Langzeitwirkung lässt sich mit der bekannten Konditionierungsvorrichtung nicht erzielen. Schwankungen in der Stärke des Spülflüssigkeitsstromes, wie sie aus vielerlei Gründen auftreten können, haben ferner eine ungleichmässige, ggf. unterbrochenen Abgabe von Konditionierungssubstanz zur Folge, so dass nicht gewährleistet ist, dass die zudosierte Menge an Konditionierungssubstanz von Spülvorgang zu Spülvorgang immer gleich ist.Known devices of the generic type include those in which the Conditioning substance over a soakable, permanent or with the rinsing liquid Intermittent element, e.g. added from an open-cell foam and those where the addition is based on a siphon effect. Conditioning devices of the first type mentioned are e.g. in EP-B-0 538 957 or EP-A-785315 described. The capillary pathways that contain the conditioning substance from a Storage vessel must cover up to the pending rinsing liquid, what are relatively long can easily render the device unusable by clogging the capillary paths can. Another consequence of this is that the amount dosed in the rinsing liquid Conditioning substance may initially be set too high, which if necessary with a undesirable environmental pollution. At on the siphon effect based conditioning devices, e.g. are known from DE-A-2916385, mainly conditioning substances in solid form can and is used it is hardly possible to dispense the conditioning substance evenly with each rinse guaranteed. Also known is a conditioning device (DE-A-19520145), the one contains a filling space of the device filling substance of pasty consistency. The Flushing liquid is passed over the surface of the filling with each flushing process in order to entrain a small amount of the pasty substance. It is not just measures against unwanted sump formation is also necessary Adjust the viscosities of the substances reacting with each other to make a to get approximately uniform release of active ingredient. After all, there is one Conditioning device (DE-A-2532963) is known, in the case of a rinsing process Current of the rinsing liquid meets a baffle plate which can be pivoted about an axis, the dynamic force of the flushing liquid flow causes a rotation of the baffle plate, which Movement is exploited to seal a spherical sealing element Engagement with an outlet opening of a reservoir for a liquid Bring conditioning substance. This is the conditioning effect of the known Conditioning device limited to the short time that a flushing liquid flow with sufficient flow energy is applied to the baffle plate. Disinfectant or Air-improving effects can therefore only be achieved for a very short time, if at all become. A basically desired long-term effect can be achieved with the known one Do not achieve conditioning device. Fluctuations in the strength of the Flushing liquid flow, as can occur for a variety of reasons, also have one uneven, possibly interrupted release of conditioning substance, so that it is not guaranteed that the metered amount of conditioning substance from the rinsing process for rinsing is always the same.
Der Erfindung liegt die Aufgabe zugrunde, eine konstruktiv einfach ausgestaltete Konditionierungsvorrichtung für die Abgabe flüssiger Konditionierungssubstanzen zu schaffen, die bei jedem Spülvorgang eine gleichmässige, zeitlich gesteuerte Wirkstoffabgabe in die Spülflüssigkeit unabhängig von der Stärke des jeweilig herrschenden Spülstromes gewährleistet. The invention has for its object a structurally simple design To provide a conditioning device for dispensing liquid conditioning substances, which with every rinsing process a uniform, time-controlled release of active ingredient in the Irrigation liquid guaranteed regardless of the strength of the prevailing rinsing flow.
Diese Aufgabe wird erfindungsgemäss durch die Merkmale des Patentanspruches 1 gelöst. Die
Menge an der Spülflüssigkeit bei jedem Spülvorgang zudosierter Konditionierungssubstanz kann
genau vorgegeben werden, indem eine Auslassöffnung einer Vorratskammer für die
Konditionierungssubstanz bei jedem Spülvorgang gezielt über eine Zeitdauer, während der ein
Auffanggefäss für die Spülflüssigkeit gefüllt ist, geöffnet und am Ende des Spülvorgangs nach
Verstreichen einer von der Durchlasskapazität einer Entleerungsöffnung des Auffanggefasses
bestimmten Zeit wieder verschlossen wird. Für die Auslösung einer Substanzabgabe ist nicht die
Stärke oder Dauer des jeweilig herrschenden Spülflüssigkeitsstromes, sondern die Füllung des
Auffanggefässes massgebend. Die z.B. desinfizierende oder luftverbessernde Eigenschaft der
Konditionierungssubstanz kann daher über den eigentlichen Spülvorgang hinaus zum Tragen
kommen. Die abgegebene Menge an Konditionierungssubstanz kann feiner gemäss einer
Weiterbildung der Erfindung dadurch weiter vergleichmässigt werden, dass sie dem Volumen
eines nicht von dem Dichtungselement eingenommenen Raumes im Inneren einer Vorkammer
der Vorratskammer entspricht, die in der Schliesstellung des Dichtungselementes mit der
Konditionierungssubstanz gefüllt und in der Freigabestellung entleert wird. Eine Sumpfbildung
in der Vorrichtung wird vermieden, da nach einem Spülvorgang keine Flüssigkeit zurückbleibt.
Die Vorrichtung erlaubt ein problemloses Nachfüllen mit flüssiger Konditionierungssubstanz.
Sie zeichnet sich daher durch eine besonders günstige Gebrauchstüchtigkeit und ferner durch
eine einfache kostengünstige Fertigungsmöglichkeit aus.This object is achieved according to the invention by the features of
Die Erfindung wird nachfolgend anhand einer Ausführungsform und der Zeichnung näher
erläutert. Es zeigen:
Die Konditionierungsvorrichtung gemäss der Erfindung setzt sich zusammen aus einem in Fig. 2
mit dem allgemeinen Bezugszeichen 1 angedeuteten Basis- oder Unterteil und einem mit dem
allgemeinen Bezugszeichen 2 angedeuteten Ober- oder Deckelteil, die durch umfänglich der
beiden Teile vorgesehene, miteinander in Eingriff bringbare Verrastmittel 3 lösbar miteinander
verbunden sein können. Am Deckelteil 2 kann ein Bügel 4 zum Anklemmen der Vorrichtung an
einem Rand einer Toilettenschüssel oder dgl. vorgesehen sein. Der Basisteil 1 und Deckelteil 2
sind vorzugsweise Formteile aus einem geeigneten Kunststoffmaterial, wie einem Polyolefin.
Andere Mateialien können ebenfalls verwendet werden.The conditioning device according to the invention is composed of one in FIG. 2
with the
Der Basisteil 1 definiert eine Vorratskammer 5 zur Aufnahme einer Menge an
Konditionierungssubstanz, die über eine Einfüllöffnung 6 im Deckelteil 2, vgl. Fig. 2, in die
Vorratskammer 5 eingefüllt werden kann, ohne dass der Deckelteil 2 abgehoben werden muss.
Von einer geeigneten, z.B. zentralen Stelle der Unterseite der Bodenwand 7 des Basisteils 1 ragt
umfänglich einer in der Bodenwand 7 eingebrachten Öffnung 10 ein dichtflanschartiger Ansatz 8
ab, der eine nicht näher bezeichnete Vorkammer schafft. Die Öffnung 10 bildet einen Einlass in
die Vorkammer bzw. eine Verbindung zwischen dieser und der Vorratskammer 5. The
Der untere freie Endbereich des Ansatzes 8 ist dichtlippenartig nach innen gekrümmt und bildet
innenseitig des Ansatzes 8 eine erste oder untere ringförmige Dichtfläche 9, mit der ein im
Ansatz 8 aufgenommenes kugelförmiges Dichtungselement 11 in dichtendem Eingriff treten
kann, um eine von der ringförmigen Dichtfläche 9 umgrenzte Auslassöffnung 12 der
Vorkammer zu verschliessen. Das Dichtungselement 11 ist frei bewegbar in der Vorkammer
aufgenommen und kann mit einer zweiten oder oberen ringförmigen Dichtfläche 13, die den
Einlass oder die Öffnung 10 umgibt, in dichtendem Eingriff treten, um die Öffnung 10 zu
verschliessen, wenn das Dichtungselement 11 unter einer Kraft aus dem dichtenden Eingriff mit
der unteren Dichtfläche 9 herausbewegt wurde, die von einem in Fig. 2 allgemein mit 14
angedeuteten Betätigungselement auf das Dichtungselement 11 ausgeübt werden kann.The lower free end region of the
Das Dichtungselement 11 wird in der in Fig. 1 und 2 gezeigten dichtenden Beziehung zur
Dichtfläche 9 längs der Auslassöffnung 12 aufgrund seines Eigengewichtes und des auf das
Dichtungselement 11 wirkenden Gefälledruckes der in der Vorratskammer 5 befindlichen
Menge an Konditionierungssubstanz gehalten.The sealing
Fig. 2 zeigt den Aufbau des Betätigungselementes 14. Das Betätigungselement 14 ist
grundsätzlich nach Art einer um eine Drehachse 15 schwenkbaren Wippe mit einem Armbereich
16 einerseitig der Drehachse 15 (in Fig. 2 rechtsseitig) und einem Armbereich in Gestalt eines
Auffanggefässes 19 anderenseitig (linksseitig) der Drehachse 15 ausgebildet. Die Drehachse 15
kann, wie Fig. 1 zeigt, zwischen gegenüberliegenden Wandabschnitten einer eine Nebenkammer
18 bildenden taschenförmigen Anformung 17 der Konditionierungsvorrichtung gelagert sein, die
aussenseitig der Vorratskammer 5 am Basisteil 1 vorgesehen ist, wie es Fig. 2 zeigt.Fig. 2 shows the structure of the actuating
Die Nebenkammer 18 ist nach oben hin offen, so dass ein Teil einer Spülflüssigkeit in einem
von oberhalb der Konditionierungsvorrichtung herabfallenden Spülflüssigkeitsstrom, vgl. Pfeile
Sp in Fig. 3, in die Nebenkammer 18 bei jedem Spülvorgang hineingelangen kann, um das
Auffanggefäss 19 des Betätigungselementes 14 zu füllen. Auf diese Weise wird auf den
linkseitigen Bereich des Betätigungselementes 14 eine nach unten gerichtete Kraft ausgeübt, die
den rechtsseitigen Armbereich 16 nach oben bewegt, um das Dichtungselement 11 aus dem
dichtenden Eingriff mit der ersten oder unteren Dichtfläche 9 heraus und in dichtendem Eingriff
mit der oberen oder zweiten Dichtfläche 13 des Ansatzes 8 zu bewegen. Die Öffnung 10 wird
demzufolge bei jedem Spülvorgang verschlossen und die Auslassöffnung 12 des Ansatzes 8
freigegeben. Unter diesen Umständen kann im freien Raum zwischen dem Dichtungselement 11
und dem Inneren des Ansatzes 8 vorhandene Konditionierungssubstanz über die Auslassöffnung
12 nach aussen treten und sich mit dem Spülflüssigkeitsstrom vermischen, vgl. Pfeile K in Fig.
3.The
Wie Fig. 2 weiter zu entnehmen ist, findet eine ständige Entleerung des Auffanggefässes 19 über
eine Drosselbohrung 20 statt, die an einem unteren Bereich in der Wand des Auffanggefässes 19
vorgesehen ist, so dass bei Beendigung eines Spülvorganges im Auffanggefäss 19 verbleibende
Spülflüssigkeit allmählich nach aussen abgeführt und dadurch die auf das Dichtungselement 11
ausgeübte Kraft aufgehoben wird. Infolge davon gelangt das Dichtungselement 11 nach jedem
Spülvorgang wieder in die die Auslassöffnung 12 abdichtende Beziehung zurück.As can also be seen in FIG. 2, the
Die auf das Betätigungselement 14 bei einem Spülvorgang ausübte Kraft setzt sich aus einer
dynamischen Komponente in Gestalt der Strömungskraft der Spülflüssigkeit, wenn diese in der
Nebenkammer 18 auf das Auffanggefäss 19 auftrifft, und dem Gewicht der im Auffanggefäss 19
zurückgehaltenen Spülflüssigkeit zusammen. Die Kraft ist daher ausreichend hoch, um das
Dichtungselement 11 gegen die Vorspannkraft aus seinem Eigengewicht und dem Gefälledruck
der in der Vorratskammer 5 bevorratenen Konditionierungssubstanz von der Schliess- in die
Freigabestellung zu bewegen. Entsprechend dem Volumen des von dem Dichtungslement 11 im
Inneren der Vorkammer belassenen Raumes kann die bei jedem Spülvorgang abgegebene Menge
an Konditionierungssubstanz genau vorgegeben werden. Die abgegebene Menge ist nicht
abhängig von der Zeitdauer, während der sich das Dichtungselement 11 in der Freigabestellung
befindet.The force exerted on the actuating
Obschon bevorzugt wird, dass das Dichtungselement in seiner Freigabestellung den Einlass ins Innere der Vorkammer verschlossen hält, versteht es sich, dass eine derartige, eine genaue Dosierung der bei jedem Spülvorgang abgegebenen Menge an Konditionierungssubstanz ermöglichende Funktion auch weggelassen und statt dessen eine permanente Fluidverbindung zwischen der Vorratskammer und der Vorkammer vorgesehen werden könnte. Ferner könnte das Betätigungselement auch ohne Auffanggefäss ausgebildet sein, so dass die bei jedem Spülvorgang einwirkende Kraft im wesentlichen durch die dynamische Strömungskraftkompente bestimmt ist. Das Dichtungselement braucht nicht notwendigerweise eine kugelförmige Konfiguration haben. Vielmehr könnte auch eine andere, z.B. zylindrische oder kegelstumpfförmige Konfiguration vorgesehen werden. Das Dichtungselement könnte auch am Armbereich des Betätigungselementes angelenkt sein. Schliesslich könnte vorgesehen werden, dass das Dichtungselement in seine Schliesstellung durch eine Feder oder dgl. vorgespannt ist. Weitere sich dem Fachmann anhand der gegebenen Lehre anbietende Modifkationen der beschriebenen Ausführungsform können vorgesehen werden, ohne dass dadurch der Schutzbereich der Patentansprüche verlassen wird.Although it is preferred that the sealing element in its release position the inlet into Keeps the interior of the antechamber closed, it is understood that such an accurate Dosage of the amount of conditioning substance dispensed with each rinsing process enabling function also omitted and instead a permanent fluid connection could be provided between the pantry and the prechamber. It could also Actuator can also be designed without a collecting vessel, so that with each Force acting on the flushing process essentially through the dynamic flow force components is determined. The sealing element does not necessarily need a spherical one Have configuration. Rather, another one, e.g. cylindrical or frustoconical configuration can be provided. The sealing element could also on Arm area of the actuator to be articulated. Finally, it could be provided that the sealing element is biased into its closed position by a spring or the like. Further modifications to the person skilled in the art based on the given teaching of Embodiment described can be provided without the Protection area of the claims is left.
