Description

"Filterpatrone zum Einsetzen in einen Wasservorratstank""Filter cartridge for insertion in a water storage tank"
Filterpatronen zum Einsetzen in einer Wasservorratstank einer Getränkemaschine, wie einer Espressomaschine oder dergleichen sind in der Regel mit einem Gehäuse ausgestattet, in dem ein aus Filtermaterial gebildetes Filterbett angeordnet ist. Derartige Filterpatronen sind beispielsweise aus der Druckschrift DE 197 17 054 bekannt.Filter cartridges for insertion in a water storage tank of a beverage machine, such as an espresso machine or the like are generally equipped with a housing in which a filter bed formed from filter material is arranged. Such filter cartridges are known for example from the publication DE 197 17 054.
Bei dieser bekannten Filterpatrone wird das Filterbett im Aufström von unten nach oben durchströmt. Dies hat zur Folge, dass durch eine Saugpumpe in der entsprechenden Getränkemaschine das Wasser durch die gesamte Filterpatrone gegen den Strömungswiderstand des Filterbettes hin angehoben werden muss. Dabei steht sowohl der Strömungswiderstand des Filterbettes, als auch die Gravitation des Wassers der Strömungsrichtung entgegen.In this known filter cartridge, the filter bed is flowed through in the upward flow from bottom to top. This has the consequence that the water must be lifted through the entire filter cartridge against the flow resistance of the filter bed through a suction pump in the corresponding beverage machine. In this case, both the flow resistance of the filter bed, as well as the gravity of the water counteract the flow direction.
Aufgabe der Erfindung ist es daher, eine Filterpatrone vorzuschlagen, bei der die Strömungsführung erleichtert ist.The object of the invention is therefore to propose a filter cartridge in which the flow guidance is facilitated.
Diese Aufgabe wird ausgehend von einer Filterpatrone gemäß dem Oberbegriff des Anspruchs 1 durch diese kennzeichnenden Merkmale gelöst.This object is achieved on the basis of a filter cartridge according to the preamble of claim 1 by these characterizing features.
Durch die in den Unteransprüchen genannten Maßnahmen sind vorteilhafte Ausführungen und Weiterbildungen der Erfindung möglich. Dementsprechend zeichnet sich eine erfindungsgemäße Filterpatrone mit einem austauschbaren Adapterteil dadurch aus, das im Filterbett wenigstens ein in Betrieb von oben nach unten durchströmter Strömungsbereich vorgesehen ist. Das Filterbett kann in diesen Bereichen demnach unter Zuhilfenahme der Gravitation durchströmt werden, sodass der Strömungswiderstand des Filterbettes wenigstens teilweise kompensiert wird.The measures mentioned in the dependent claims advantageous embodiments and developments of the invention are possible. Accordingly, a filter cartridge according to the invention with an exchangeable adapter part is distinguished by the fact that at least one flow region through which the flow passes from top to bottom is provided in the filter bed. The filter bed can thus be flowed through in these areas with the aid of gravity, so that the flow resistance of the filter bed is at least partially compensated.
In einer besonderen Ausführung der Erfindung umfasst das Adapterteil eine mit dem Wasservorratstank in Verbindung stehende Steigleitung zur Aufnahme des Wassers aus dem Wasservorratstank und zur Weiterleitung in die Filterpatrone aufweist .In a particular embodiment of the invention, the adapter part comprises a standing with the water storage tank riser for receiving the water from the water storage tank and for forwarding into the filter cartridge.
Ein derart ausgestaltetes Adapterteil ermöglicht somit nicht nur die ausgangsseitige Anpassung einer Filterpatrone an alle gängigen Anschlusselemente von Wasservorratstanks durch entsprechenden Austausch des Adapterteils, sondern es stellt zugleich auch die Wasserzufuhr in die Filterpatrone sicher. Auf diese Weise ist eine separate, entsprechend tief angeordnete Wassereintrittsöffnung bei der Filterpatrone entbehrlich. Außerdem ist eine Entleerung desSuch a designed adapter part thus not only allows the output side adjustment of a filter cartridge to all common connection elements of water storage tanks by appropriate replacement of the adapter part, but it also ensures the supply of water into the filter cartridge at the same time. In this way, a separate, correspondingly deeply arranged water inlet opening in the filter cartridge is dispensable. In addition, an emptying of the
Wasservorratstanks bis auf Höhe der Wassereintrittsöffnung im Adapterteil möglich. Insbesondere kann die Filterpatrone auch in einer der Länge des Adapterteils entsprechenden Höhe oberhalb des Tankbodens angeordnet werden, wobei die Wasserzufuhr über den Adapter gewährleistet ist.Water supply tanks possible up to the height of the water inlet opening in the adapter part. In particular, the filter cartridge can also be arranged in a height corresponding to the length of the adapter part above the tank bottom, wherein the water supply is ensured by the adapter.
Vorteilhafterweise umfasst die Filterpatrone weiterhin eine mit der Steigleitung des Adapterteils verbindbare Steigleitung, die oberhalb des Filterbettes in der Filterpatrone ausmündet. In dieser Bauform ist die Durchströmung des gesamten Filterbettes im sogenannte Abstromverfahren von oben nach unten möglich, d. h. das gesamte Filterbett wird hierbei unter Zuhilfenahme der Gravitation durchströmt.Advantageously, the filter cartridge further comprises a connectable with the riser of the adapter part riser, which opens above the filter bed in the filter cartridge. In this design, the flow through the entire filter bed in the so-called downflow from top to bottom is possible, ie the entire filter bed is in this case with the aid of Gravity flows through.
Die oberhalb des Filterbettes in der Filterpatrone ausmündende Steigleitung kann dabei in die Filterpatrone bzw. in deren Gehäuse integriert werden, sodass sie vollständig im Innern der Patrone verläuft, oder aber auch außerhalb der Patrone als separate Leitung angeordnet werden.The rising above the filter bed in the filter cartridge riser can be integrated into the filter cartridge or in the housing so that it runs completely inside the cartridge, or even outside the cartridge are arranged as a separate line.
Vorzugsweise wird das Adapterteil mit einer Dichtung versehen, die für den dichten Abschluss der Auslassleitung am bzw. im Anschlusselement des Wasservorratstanks sorgt. Ein solcher dichter Abschluss stellt sicher, dass ausschließlich gefiltertes Wasser die Ausgangsöffnung des Wasservorratstanks erreicht und nicht etwa ungefiltertes Wasser beigemischt wird.Preferably, the adapter part is provided with a seal, which ensures the tight completion of the outlet on or in the connection element of the water storage tank. Such a tight seal ensures that only filtered water reaches the outlet opening of the water storage tank and not admixed with unfiltered water.
Eine solche Dichtung wird vorteilhafterweise durch eine Axialdichtung für den dichten Abschluss der Auslassleitung des Adapterteils am Behälterboden gebildet. Eine solche Axialdichtung bietet eine einfache Handhabung, da durch axiales Andrücken der Dichtung am Behälterboden der erforderliche dichte Formschluss erzielt wird. Reibungskräfte, die beispielsweise beim Anpressen einer Radialdichtung an einen entsprechend geformten radialen Dichtsitz auftreten können, sind hierbei vermieden.Such a seal is advantageously formed by an axial seal for the tight completion of the outlet of the adapter part at the container bottom. Such an axial seal provides easy handling, since the required tight positive locking is achieved by axial pressing of the seal on the container bottom. Frictional forces that may occur, for example, when pressing a radial seal to a correspondingly shaped radial sealing seat, are avoided.
Darüber hinaus ist mit Hilfe einer Axialdichtung problemlos eine definierte Betriebsposition der Filterpatrone bzw. des Adapterteils gegebenenfalls unter Zuhilfenahme eines Anschlags möglich.In addition, with the help of an axial seal a defined operating position of the filter cartridge or the adapter part, possibly with the aid of a stop possible.
Eine erfindungsgemäße Filterpatrone wird bevorzugt in einem Wasservorratstank eingesetzt, der ein Rückschlagventil aufweist, sodass der Wasservorratstank aus der entsprechenden Getränkemaschine entnehmbar ist, ohne dass Wasser durch dessen Bodenöffnung austreten kann. Der Wasservorratstank kann somit zum Befüllen aus der Maschine entnommen werden.A filter cartridge according to the invention is preferably used in a water storage tank having a check valve, so that the water storage tank can be removed from the corresponding beverage machine without water can escape through the bottom opening. The water storage tank can thus be removed for filling from the machine.
Die entsprechende Getränkemaschine wird wiederum vorteilhafterweise mit einer Saugpumpe versehen, um die zuverlässige Durchströmung der Filterpatrone und somit die zuverlässige Entnahme der gewünschten Wassermenge für die Getränkemaschine sicherzustellen.The corresponding beverage machine is in turn advantageously provided with a suction pump to ensure the reliable flow through the filter cartridge and thus the reliable removal of the desired amount of water for the beverage machine.
Im Falle einer Durchströmung des Filterbetts im Abstrom wird, wie oben angeführt, der Strömungswiderstand des Filterbettes durch die Gravitation wenigstens teilweise kompensiert, sodass die Saugpumpe weniger groß dimensioniert werden muss.In the case of a flow through the filter bed in the outflow, as stated above, the flow resistance of the filter bed is at least partially compensated by gravity, so that the suction pump must be dimensioned less large.
Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt und wird anhand der Figur nachfolgend näher erläutert.An embodiment of the invention is illustrated in the drawing and will be explained with reference to the figure below.

Figur 1 eine schematische Schnittdarstellung einer ersten Ausführungsform der Erfindung und,FIG. 1 is a schematic sectional view of a first embodiment of the invention and
Figur 2 eine schematische Schnittdarstellung einer zweiten Ausführungsform.Figure 2 is a schematic sectional view of a second embodiment.
In Figur 1 ist eine Filterpatrone 1 mit Filtergehäuse 2 und erfindungsgemäßem Adapterteil 3 dargestellt. Das Adapterteil 3 ist auf nicht näher dargestellte Weise, beispielsweise durch einen Klipsverschluss mit einem Filtergehäuse 2 verbindbar.FIG. 1 shows a filter cartridge 1 with filter housing 2 and adapter part 3 according to the invention. The adapter part 3 is connected in a manner not shown, for example by a clip closure with a filter housing 2.
Das Adapterteil 3 ist in Form eines Doppelrohrs ausgebildet, wobei die Wandung des Außenrohrs 4 in der dargestellten Ausführungsform einen bodenseitigen Anschlusssockel 5 eines Wasservorratstanks umschließt, von dem vorliegend nur der Tankboden 6 dargestellt ist. Zentral im Innern des Außenrohres 4 ist ein Innenrohr 7 mit einer bodenseitigen Axialdichtung in Form eines Dichtbalgs angebracht. Das Innenrohr 7 mündet bodenseitig in eine Auslassöffnung 9 des Tankbodens 6. An der Oberseite ist das Adapterteil 3 mit einem Deckel 10 verschlossen, der eine Durchgangsöffnung 11 in eine durch eine Trennwand 12 im Filtergehäuse 2 gebildete Einlasskammer 13 aufweist. Die Durchgangsöffnung 11 ist im Bereich des Zwischenraums zwischen dem Innenrohr 7 und dem Außenrohr 4 angeordnet.The adapter part 3 is in the form of a double tube, wherein the wall of the outer tube 4 in the illustrated embodiment, a bottom-side terminal socket 5 a Water reservoir tanks encloses, of which in the present case only the tank bottom 6 is shown. Centrally in the interior of the outer tube 4, an inner tube 7 is attached with a bottom-side axial seal in the form of a sealing bellows. The inner tube 7 opens on the bottom side into an outlet opening 9 of the tank bottom 6. At the top, the adapter part 3 is closed with a cover 10, which has a passage opening 11 in an inlet chamber 13 formed by a partition wall 12 in the filter housing 2. The passage opening 11 is arranged in the region of the intermediate space between the inner tube 7 and the outer tube 4.
Die Trennwand 12 bildet an ihrem oberen Ende einen Überlauf 14 in die Auslasskammer 15, die bodenseitig mit einer Durchgangsöffnung 16 mit dem Innenrohr 7 in Verbindung steht.The partition wall 12 forms at its upper end an overflow 14 in the outlet chamber 15, which is on the bottom side with a passage opening 16 with the inner tube 7 in connection.
Die Strömungsrichtung des Adapters ist durch Pfeile dargestellt. Im Bodenbereich kann das Wasser über eine entsprechende Durchgangsöffnung im Außenrohr 4, die beispielsweise in Form von Längsschlitzen (nicht näher dargestellt) oder durch einen einfachen Abstand des Außenrohrs 4 zum Boden 6 vorliegen kann. Der Anschlusssockel 5 ist zu diesem Zweck ebenfalls mit Öffnungen, beispielsweise mit Schlitzen in axialer Richtung versehen (ebenfalls nicht dargestellt) , sodass das Wasser ungehindert in den Zwischenraum zwischen dem Außenrohr 4 und den Innenrohr 7 strömen kann.The flow direction of the adapter is shown by arrows. In the bottom region, the water can be present via a corresponding passage opening in the outer tube 4, which may be in the form of longitudinal slots (not shown in detail) or by a simple distance of the outer tube 4 to the bottom 6, for example. The connection base 5 is also provided for this purpose with openings, for example with slots in the axial direction (also not shown), so that the water can flow unhindered into the space between the outer tube 4 and the inner tube 7.
Dieser Zwischenraum bildet eine Steigleitung 17, über die das Wasser in die Einlasskammer 13 gelangt. Über den Überlauf 14 gelangt das Wasser in die Auslasskammer 15 und somit in das Innenrohr 7, über das es durch die Auslassöffnung 9 des Behälterbodens 6 abfließen kann. Die Einlasskammer 13 sowie die Auslasskammer 15 sind im vorliegenden Ausführungsbeispiel mit Filtermaterial, beispielsweise Ionentauscherharz und/oder Aktivkohle oder dergleichen gefüllt. In dieser Ausführungsform bildet die Auslasskammer 15 einen Strömungsbereich, der im Abstrom, d. h. von oben nach unten durchströmt wird und somit den Strömungswiderstands des Filterbettes wenigstens teilweise kompensiert und somit den Strömungswiderstand des Filterbettes wenigstens teilweise kompensiert.This space forms a riser 17, via which the water enters the inlet chamber 13. Via the overflow 14, the water enters the outlet chamber 15 and thus into the inner tube 7, via which it can flow through the outlet opening 9 of the container bottom 6. The inlet chamber 13 and the outlet chamber 15 are filled in the present embodiment with filter material, such as ion exchange resin and / or activated carbon or the like. In this Embodiment, the outlet chamber 15 forms a flow region, which is flowed through in the outflow, ie from top to bottom and thus at least partially compensates the flow resistance of the filter bed and thus at least partially compensates the flow resistance of the filter bed.
Die Ausführungsvariante gemäß Figur 2 entspricht im Wesentlichen dem erstgenannten Ausführungsbeispiel, wobei die Steigleitung 17 nunmehr seitlich neben dem Auslassrohr 18 angeordnet und mit einer Steigleitung 19 der Filterpatrone 20 verbunden ist. über die Steigleitung 19 gelangt das Wasser von oben in das Filterbett 21, das infolgedessen vollständig im Abstrom durchströmt wird. Bei dieser Ausführungsform kann beispielsweise ein außenumschließender Anschlusssockel 22 im Behälterboden vorgesehen werden. Alternativ oder in Kombination hierzu kann auch ein nach innen in das Auslassrohr 18 hineinstehender Anschlusssockel 23 vorgesehen werden. Über ein Dichtelement 24, das beispielsweise ebenso wie im Ausführungsbeispiel gemäß Figur 1 als Axialdichtung 8 ausgelegt sein kann, wird das Auslassrohr 18 gegenüber der Außenumgebung abgedichtet, sodass lediglich gefiltertes Wasser in die Austrittsöffnung 25 des Tankbodens 26 gelangen kann. The embodiment variant according to FIG. 2 essentially corresponds to the first-mentioned exemplary embodiment, wherein the riser 17 is now arranged laterally next to the outlet pipe 18 and connected to a riser 19 of the filter cartridge 20. via the riser 19, the water passes from above into the filter bed 21, which is consequently completely flowed through in the outflow. In this embodiment, for example, an outer-enclosing terminal socket 22 may be provided in the container bottom. Alternatively or in combination with this, a connection socket 23, which projects inwards into the outlet pipe 18, can also be provided. Via a sealing element 24, which may be designed, for example, as in the embodiment of Figure 1 as axial seal 8, the outlet pipe 18 is sealed against the outside environment, so that only filtered water can get into the outlet opening 25 of the tank bottom 26.
