Definitions
- the invention relates to a cleaning device for beverage lines, in particular dispensing lines, with an automatically operating four-way switch valve, which has a housing with a supply line connection connected to a cleaning liquid supply line, with two dispensing line connections connected to the ends of a dispensing line loop and with a drain connection and has a valve slide which switches over when at least one cleaning body conveyed by the dispensing line loop strikes it on the end face.
- Such a cleaning device is known from DE-A-33 47 003.
- the cleaning liquid in particular water, is conveyed by the domestic water line or a pump under a certain pressure and flows through the dispensing line loop with the entrainment of one or more cleaning bodies.
- These cleaning bodies are mostly designed as sponges, which are adapted to the tap line diameter; it can also be pearls or other cleaning elements.
- the changeover valve switches to the other end position under the influence of the liquid pressure.
- the cleaning fluid then flows through the dispensing line loop in the opposite direction, again taking the cleaning bodies with it, whereupon the work cycle is repeated.
- the invention is therefore based on the object of specifying a cleaning device of the type described at the outset which offers greater security with regard to switching.
- This object is achieved in that a switching valve which temporarily interrupts the inflow of the cleaning liquid is arranged in the feed line.
- this switching valve increases the switching security.
- a high flow resistance is present, for example, in dispensing lines which assert a cooling position and have a correspondingly long length, or in dispensing lines for non-alcoholic beverages (AFG area) which only have an inside diameter of 5 mm instead of the 7 mm customary for beer lines.
- the switching valve also has other advantages.
- the cleaning bodies only advance in sections and therefore more slowly on average. Since even standing cleaning liquid loosens dirt as a result of the longer exposure time, it can be taken away more easily by the cleaning bodies. With the same fluid consumption, cleaning is more intensive and therefore better. Conversely, the same cleaning effect can be achieved with less consumption of cleaning fluid.
- the switching processes lead to vibrations in the liquid column, which also help to loosen dirt.
- the switching valve is a solenoid valve. This is easy to operate with a small design.
- the switching valve can be controlled by a timer. If this timer is effective not only in the area of the changeover time, but during the entire cleaning period, the above-mentioned improved cleaning effect is also obtained because of the lower average speed of the cleaning bodies.
- the switching valve and the timer element preferably form a structural unit. This can be installed in the supply line without difficulty.
- the switching valve forms an attachment to the four-way switching valve.
- the housing of the changeover valve forms a stable basis for the switching valve or the structural unit consisting of switching valve and timer element. The subsequent part of the supply line is not burdened by this switching valve.
- the timer can open and close the switching valve for approximately the same length of time.
- the intensive cleaning is hereby taken into account.
- the timer can preferably be switched on together with a device that conveys the cleaning liquid. Whenever, for example, the feed pump is switched on, the timer is also effective.
- a four-way switch valve 1 has a housing 2 with a supply connection 3, which is connected to a cleaning liquid supply line 4, two dispensing line connections 5 and 6, which are connected to the ends of a dispensing line loop 7, and a drain connection 8.
- a slide 10 is axially displaceable, which has two valve openings 11 and 12 in an axial groove 13 on the circumference of the slide.
- the valve opening 11 is connected via a channel 14 in the slide 10 with flow openings 15 on the end face 16 of the slide, the valve opening 12 via a channel 17 running in the slide with flow openings 18 on the end face 19 of the slide.
- the respective one slide opening cooperates with the end face 20 of a supply connector 21, the other valve opening is connected to the drain connection 8 via a connection space 22.
- Cleaning liquid is fed from a container 23 by means of a conveying device 24, here a pump 26 driven by an electric motor 25, into the feed line 4 under pressure. It arrives in the illustrated Position of the slider 10 via the supply pipe 21 and the valve opening 11 as well as via the flow openings 15 and the tap line connection 4 in the tap line loop 7. It takes cleaning body 27, of which a sponge is shown, with it. The cleaning liquid then goes from the other dispensing line connection 6 via the flow openings 18 and the valve opening 12 to the drain connection. As soon as the cleaning bodies 27 reach the other end face 19, the flow openings 18 are covered, whereupon the switching should take place by axially displacing the slide 10 due to the pressure of the pump 26. Then the work cycle is repeated in the opposite direction.
- a switching valve 28 with an actuating magnet 29 is provided in the feed line 4. This is actuated by a timer switch 30, which is applied to the mains voltage U with the aid of a double switch 31 together with the conveying device 24. As soon as the timer 30 is activated, it actuates the switching valve 28 in such a way that it is in each case for 3 to 4 seconds. is open. Then it is closed for the same time or for a shorter time, whereby the inflow of the cleaning liquid is interrupted. The resulting pressure changes in the dispensing line loop 7 have the effect that when the cleaning body or bodies 27 have closed the flow openings 15 and 18, the slide 10 is brought into the other working position with certainty.
- Fig. 2 shows schematically how the solenoid valve 28 is attached to the housing 2 of the four-way switch valve 1 and in turn forms a structural unit with the timer element 30.
- the house water connection can also be used instead of the pump 26, so that water is supplied as a cleaning liquid under the usual water line pressure.
- the flow openings 15 and 18 need not be attached to the end face of the actual slide body, but can be located on the end face of components connected to the slide 10.
- a four-way switch valve reference is made to DE-A-33 47 003.
- the function of the switching valve is, however, also effective in the case of four-way changeover valves which are constructed differently and can be operated automatically by the liquid pressure.
- the switching valve was a 1.010 type solenoid valve from A + K Müller in Dusseldorf and the time switch 30 was an MV-IS1 interval switch from Kristensen GmbH in Harrislee.

Abstract
Description
Die Erfindung bezieht sich auf eine Reinigungsvorrichtung für Getränkeleitungen, insbesondere Schankleitungen, mit einem automatisch arbeitenden Vier-Wege-Umschaltventil, das ein Gehäuse mit einem mit einer Reinigungsflüssigkeits-Zuleitung verbundenen Zuleitungsanschluß, mit zwei mit den Enden einer Schankleitungsschleife verbundenen Schankleitungsanschlüssen und mit einem Ablaufanschluß sowie einen Ventilschieber aufweist, der umschaltet, wenn mindestens ein durch die Schankleitungsschleife geförderter Reinigungskörper stirnseitig auf ihn auftrifft.The invention relates to a cleaning device for beverage lines, in particular dispensing lines, with an automatically operating four-way switch valve, which has a housing with a supply line connection connected to a cleaning liquid supply line, with two dispensing line connections connected to the ends of a dispensing line loop and with a drain connection and has a valve slide which switches over when at least one cleaning body conveyed by the dispensing line loop strikes it on the end face.
Eine solche Reinigungsvorrichtung ist aus DE-A-33 47 003 bekannt. Die Reinigungsflüssigkeit, insbesondere Wasser, wird von der Hauswasserleitung oder einer Pumpe unter einem gewissen Druck gefördert und durchfließt die Schankleitungsschleife unter Mitnahme von einem oder mehreren Reinigungskörpern. Diese Reinigungskörper werden zumeist als Schwämmchen, welche dem Schankleitungsdurchmesser angepaßt sind, ausgebildet; es kann sich aber auch um Perlen oder andere Reinigungselemente handeln.Such a cleaning device is known from DE-A-33 47 003. The cleaning liquid, in particular water, is conveyed by the domestic water line or a pump under a certain pressure and flows through the dispensing line loop with the entrainment of one or more cleaning bodies. These cleaning bodies are mostly designed as sponges, which are adapted to the tap line diameter; it can also be pearls or other cleaning elements.
Sobald die Reinigungskörper das Schleifenende erreicht haben und an der Stirnseite des Schiebers vorgesehene Durchflußöffnungen abdecken, schaltet das Umschaltventil unter dem Einfluß des Flüssigkeitsdrucks in die andere Endlage. Die Reinigungsflüssigkeit durchströmt dann, wiederum unter Mitnahme der Reinigungskörper, die Schankleitungsschleife in entgegengesetzter Richtung, worauf sich das Arbeitsspiel wiederholt.As soon as the cleaning bodies have reached the end of the loop and cover the flow openings provided on the end face of the slide, the changeover valve switches to the other end position under the influence of the liquid pressure. The cleaning fluid then flows through the dispensing line loop in the opposite direction, again taking the cleaning bodies with it, whereupon the work cycle is repeated.
In manchen Fällen wurde beobachtet, daß das Vier-Wege-Umschaltventil beim Auftreffen der Reinigungskörper nicht umschaltet. Versuche, die Reibung des Schiebers zu vermindern, führten nur zu einem begrenzten Erfolg.In some cases it has been observed that the four-way switch valve does not switch when the cleaning bodies hit it. Attempts to reduce slide friction have met with limited success.
Der Erfindung liegt daher die Aufgabe zugrunde, eine Reinigungsvorrichtung der eingangs beschriebenen Art anzugeben, die hinsichtlich des Umschaltens eine höhere Sicherheit bietet.The invention is therefore based on the object of specifying a cleaning device of the type described at the outset which offers greater security with regard to switching.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß in der Zuleitung ein den Zufluß der Reinigungsflüssigkeit zeitweilig unterbrechendes Schaltventil angeordnet ist.This object is achieved in that a switching valve which temporarily interrupts the inflow of the cleaning liquid is arranged in the feed line.
Ganz überraschend wurde festgestellt, daß durch die Betätigung dieses Schaltventils die Umschaltsicherheit erhöht wird. Dies gilt insbesondere für Rohrleitungsschleifen, die einen großen Strömungswiderstand haben, oder für Reinigungsvorrichtungen, bei denen die Reinigungsflüssigkeit mit begrenztem Druck zugeführt wird. Ein hoher Strömungswiderstand ist beispielsweise bei Schankleitungen vorhanden, die eine Kühllage durchsetzen und eine entsprechend große Länge haben, oder bei Schankleitungen für alkoholfreie Getränke (AFG-Bereich), die nur einen Innendurchmesser von 5 mm statt der für Bierleitungen üblichen 7 mm haben.It was surprisingly found that the actuation of this switching valve increases the switching security. This applies in particular to pipe loops that have a high flow resistance or to cleaning devices in which the cleaning liquid is supplied with limited pressure. A high flow resistance is present, for example, in dispensing lines which assert a cooling position and have a correspondingly long length, or in dispensing lines for non-alcoholic beverages (AFG area) which only have an inside diameter of 5 mm instead of the 7 mm customary for beer lines.
Der Wirkungsmechanismus ist nicht bekannt. Es wird aber vermutet, daß normalerweise der Strömungswiderstand in der Schankleitungsschleife einen Druckabfall hervorruft, so daß an deren der Zuflußseite abgewandten Ende nur noch ein Teil des eingangsseitig vorhandenen Drucks wirksam ist, der zum Umschalten nicht mehr ausreicht. Wird dagegen das Schaltventil verwendet, steht jeweils unmittelbar nach dem Öffnen nahezu der volle Eingangsdruck auch am entgegengesetzten Schankleitungsschleifenende zur Verfügung. Ist hiermit die Ruhereibung des Schiebers erst einmal überwunden, genügt ein geringerer Druck, um ihn in die andere Arbeitslage zu bringen.The mechanism of action is not known. However, it is assumed that normally the flow resistance in the tap line loop causes a pressure drop, so that at its end facing away from the inflow side only part of the pressure present on the inlet side is effective, which is no longer sufficient for switching. If, on the other hand, the switching valve is used, almost the full inlet pressure is available at the opposite end of the tap line immediately after opening. Once this has overcome the idle friction of the slide, a lower pressure is sufficient to bring it into the other working position.
Das Schaltventil bringt auch noch andere Vorteile mit sich. Die Reinigungskörper rücken immer nur abschnittsweise und daher im Mittel langsamer vor. Da auch stillstehende Reinigungsflüssigkeit infolge der längeren Einwirkzeit Schmutz löst, kann dieser von den Reinigungskörpern leichter mitgenommen werden. Bei gleichem Flüssigkeitsverbrauch ergibt sich eine intensivere und daher bessere Reinigung. Umgekehrt kann der gleiche Reinigungseffekt bei geringerem Verbrauch an Reinigungsflüssigkeit erzielt werden. Darüberhinaus führen die Schaltvorgänge zu Schwingungen in der Flüssigkeitssäule, die ebenfalls helfen, Schmutz zu lösen.The switching valve also has other advantages. The cleaning bodies only advance in sections and therefore more slowly on average. Since even standing cleaning liquid loosens dirt as a result of the longer exposure time, it can be taken away more easily by the cleaning bodies. With the same fluid consumption, cleaning is more intensive and therefore better. Conversely, the same cleaning effect can be achieved with less consumption of cleaning fluid. In addition, the switching processes lead to vibrations in the liquid column, which also help to loosen dirt.
Bei einer bevorzugten Ausführungsform ist das Schaltventil ein Magnetventil. Dieses läßt sich bei kleiner Bauform leicht betätigen.In a preferred embodiment, the switching valve is a solenoid valve. This is easy to operate with a small design.
Im einfachsten Fall und wenn es lediglich auf das Umschalten des Schiebers ankommt, genügt es, mit dem Schaltventil den Zufluß der Reinigungsflüssigkeit kurzzeitig zu unterbrechen, wenn die Reinigungskörper das Ende der Schankleitungsschleife erreicht haben. Dies kann von Hand oder durch einen automatischen Schaltvorgang, beispielsweise ausgelöst durch einen die Reinigungskörper erfassenden Sensor, erfolgen.In the simplest case and when it is only a matter of switching the slide, it is sufficient to briefly interrupt the inflow of the cleaning liquid with the switching valve when the cleaning bodies have reached the end of the dispensing line loop. This can be done manually or by an automatic switching process, for example triggered by a sensor that detects the cleaning bodies.
Günstiger ist es aber, den Unterbrechungsvorgang mehrfach zu wiederholen, weil hierdurch die Umschaltsicherheit noch verbessert wird. Daher empfiehlt es sich, daß das Schaltventil durch ein Zeitschaltglied steuerbar ist. Wenn dieses Zeitschaltglied nicht nur im Bereich des Umschaltzeitpunkts wirksam ist, sondern während der gesamten Reinigungsdauer, erhält man auch die oben erwähnte verbesserte Reinigungswirkung wegen der geringeren Durchschnittsgeschwindigkeit der Reinigungskörper.However, it is cheaper to repeat the interruption process several times because this improves the switchover safety. It is therefore recommended that the switching valve can be controlled by a timer. If this timer is effective not only in the area of the changeover time, but during the entire cleaning period, the above-mentioned improved cleaning effect is also obtained because of the lower average speed of the cleaning bodies.
Vorzugsweise bilden das Schaltventil und das Zeitschaltglied eine Baueinheit. Diese kann ohne Schwierigkeiten in die Zuleitung eingebaut werden.The switching valve and the timer element preferably form a structural unit. This can be installed in the supply line without difficulty.
Ebenfalls ist es günstig, wenn das Schaltventil einen Anbauteil zum Vier-Wege-Umschaltventil bildet. Das Gehäuse des Umschaltventils stellt eine stabile Basis für das Schaltventil bzw. die aus Schaltventil und Zeitschaltglied bestehende Baueinheit dar. Der anschließende Teil der Zuleitung wird durch dieses Schaltventil nicht belastet.It is also favorable if the switching valve forms an attachment to the four-way switching valve. The housing of the changeover valve forms a stable basis for the switching valve or the structural unit consisting of switching valve and timer element. The subsequent part of the supply line is not burdened by this switching valve.
Besonders gute Resultate haben sich gezeigt, wenn das Zeitschaltglied das Schaltventil jeweils nur für wenige Sekunden, also etwa 1 bis 5 sek., öffnet. Eine Öffnungszeit von 3 bis 4 sek. hat sich als besonders wirksam herausgestellt. Schwankungen ergeben sich natürlich in Abhängigkeit vom zur Verfügung stehenden Eingangsdruck und den speziellen Daten der zu reinigenden Schankanlage.Particularly good results have been shown when the timer opens the switching valve only for a few seconds, that is to say about 1 to 5 seconds. An opening time of 3 to 4 seconds. has proven to be particularly effective. Fluctuations naturally arise depending on the available inlet pressure and the special data of the dispensing system to be cleaned.
Ferner kann das Zeitschaltglied das Schaltventil für etwa gleich lange Zeiten öffnen und schließen. Hiermit wird der intensiven Reinigung Rechnung getragen.Furthermore, the timer can open and close the switching valve for approximately the same length of time. The intensive cleaning is hereby taken into account.
Es genügt aber für das Umschalten, wenn das Zeitschaltglied das Schaltventil jeweils nur kurzzeitig schließt.However, it is sufficient for the switchover if the time switching element closes the switching valve only briefly in each case.
Mit Vorzug ist das Zeitschaltglied zusammen mit einer die Reinigungsflüssigkeit fördernden Einrichtung einschaltbar. Immer dann, wenn beispielsweise die Förderpumpe eingeschaltet wird, ist auch das Zeitschaltglied wirksam.The timer can preferably be switched on together with a device that conveys the cleaning liquid. Whenever, for example, the feed pump is switched on, the timer is also effective.

Ein Vier-Wege-Umschaltventil 1 besitzt ein Gehäuse 2 mit einem Zuleitungsanschluß 3, der mit einer Reinigungsflüssigkeit-Zuleitung 4 verbunden ist, zwei Schankleitungsanschlüssen 5 und 6, die mit den Enden einer Schankleitungsschleife 7 verbunden sind, und einen Ablaufanschluß 8. In einer Bohrung 9 ist ein Schieber 10 axial verschiebbar, der zwei Ventilöffnungen 11 und 12 in einer Axialnut 13 am Schieberumfang aufweist. Die Ventilöffnung 11 ist über einen Kanal 14 im Schieber 10 mit Durchflußöffnungen 15 an der Stirnseite 16 des Schiebers, die Ventilöffnung 12 über einen im Schieber verlaufenden Kanal 17 mit Durchflußöffnungen 18 an der Stirnseite 19 des Schiebers verbunden. Die jeweils eine Schieberöffnung wirkt mit der Stirnseite 20 eines Zuleitungsstutzen 21 zusammen, die jeweils andere Ventilöffnung steht über einen Verbindungsraum 22 mit dem Ablaufanschluß 8 in Verbindung.A four-way switch valve 1 has a
Reinigungsflüssigkeit wird aus einem Behälter 23 mittels einer fördernden Einrichtung 24, hier einer durch einen Elektromotor 25 angetriebenen Pumpe 26, unter Druck in die Zuleitung 4 gespeist. Sie gelangt in der veranschaulichten Stellung des Schiebers 10 über den Zuleitungsstutzen 21 und die Ventilöffnung 11 sowie über die Durchflußöffnungen 15 und den Schankleitungsanschluß 4 in die Schankleitungsschleife 7. Sie nimmt dabei Reinigungskörper 27, von denen hier ein Schwämmchen dargestellt ist, mit. Die Reinigungsflüssigkeit geht dann vom anderen Schankleitungsanschluß 6 über die Durchflußöffnungen 18 und die Ventilöffnung 12 zum Ablaufanschluß. Sobald die Reinigungskörper 27 die andere Stirnseite 19 erreichen, werden die Durchflußöffnungen 18 abgedeckt, worauf das Umschalten durch axiale Verlagerung des Schiebers 10 aufgrund des Drucks der Pumpe 26 erfolgen sollte. Danach wiederholt sich das Arbeitsspiel in umgekehrter Richtung.Cleaning liquid is fed from a
Um dieses Umschalten mit Sicherheit bewerkstelligen zu können, ist in der Zuleitung 4 ein Schaltventil 28 mit einem Betätigungsmagneten 29 vorgesehen. Dieses wird von einem Zeitschaltglied 30 betätigt, das mit Hilfe eines Doppelschalters 31 zusammen mit der fördernden Einrichtung 24 an die Netzspannung U gelegt wird. Sobald das Zeitschaltglied 30 wirksam gemacht wird, betätigt es das Schaltventil 28 derart, daß es jeweils für 3 bis 4 sek. geöffnet ist. Dann wird es für die gleiche Zeit oder eine kürzere Zeit geschlossen, wodurch der Zufluß der Reinigungsflüssigkeit unterbrochen wird. Die hierdurch in der Schankleitungsschleife 7 auftretenden Druckänderungen bewirken, daß dann, wenn der oder die Reinigungskörper 27 die Durchflußöffnungen 15 bzw. 18 verschlossen haben, der Schieber 10 mit Sicherheit in die jeweils andere Arbeitsstellung gebracht wird.In order to be able to accomplish this switching with certainty, a

Abweichungen von den dargestellten Ausführungsformen sind in vielfacher Hinsicht möglich, ohne den Grundgedanken der Erfindung zu verlassen. Beispielsweise kann statt der Pumpe 26 auch der Hauswasseranschluß verwendet werden, so daß Wasser als Reinigungsflüssigkeit unter dem üblichen Wasserleitungsdruck zugeführt wird. Die Durchflußöffnungen 15 und 18 brauchen nicht an der Stirnfläche des eigentlichen Schieberkörpers angebracht zu sein, sondern können sich an der Stirnfläche von mit dem Schieber 10 verbundenen Bauelementen befinden. Als Beispiel für den Aufbau eines Vier-Wege-Umschaltventils wird auf DE-A-33 47 003 verwiesen. Die Funktion des Schaltventils ist aber auch bei anders aufgebauten, durch den Flüssigkeitsdruck automatisch betätigbaren Vier-Wege-Umschaltventilen wirksam.Deviations from the illustrated embodiments are possible in many respects without departing from the basic idea of the invention. For example, the house water connection can also be used instead of the
In einem Ausführungsbeispiel war das Schaltventil ein Magnetventil vom Typ 1.010 der Firma A+K Müller in Düsseldorf und das Zeitschaltglied 30 ein Intervallschalter MV-IS1 der Firma Kristensen GmbH in Harrislee.In one exemplary embodiment, the switching valve was a 1.010 type solenoid valve from A + K Müller in Dusseldorf and the
