Abstract

In a water jet injection device for use with dispensers for producing and dispensing beverages mixed of fruit syrup or concentrate there is provided a simple rinsing system which, if need arises, disturbs the water jet of the injection device with the aid of a rod-type member adjustable from outside in such a manner that in the mixing chamber an excess pressure and turbulent flow are generated in place of a vacuum, whereby the mixing chamber is separated from the supply conduit for fruit syrup or the like and an intensive cleaning of all of the parts of the injection device contacting the mixed beverage is effected with the aid of the water of the water jet.

Description

Die Erfindung betrifft eine Wasserstrahl-Injektionsvorrichtung an Dispensern zum Herstellen und Abgeben von Mischgetränken aus Fruchtsirup oder Konzentraten und Wasser mit den Merkmalen des Oberbegriffs des Anspruchs 1. Diese Vorrichtung kann auch zum Mischen von Wasser mit Pasten, Brei oder dgl. dienen, um z.B. Kakao-Getränke, Suppen, Seifengemische oder dgl. herzustellen.The invention relates to a water jet injection device on dispensers for producing and dispensing mixed drinks from fruit syrup or concentrates and water with the features of the preamble of claim 1. This device can also be used to mix water with pastes, porridge or the like, for example to To produce cocoa drinks, soups, soap mixtures or the like.

Eine solche Vorrichtung ist z.B. aus der DE-OS 32 34 957 bekannt.Such a device is e.g. known from DE-OS 32 34 957.

Es ist notwendig und auch meist Üblich, der Zuleitung für den Sirup oder das Konzentrat ein Rückschlagventil zuzuordnen. Dies ist erforderlich, um bei Auftreten von Störungen einen Eintritt des Wassers oder des Mischgetränkes in diese Zuleitung zu verhindern. Ein solches Rückschlagventil ist auch erforderlich, um die Mischkammer und alle mit dem Mischgetränk in Kontakt stehenden Teile des Systems aus hygienischen Gründen mit Wasser zu spülen und zu reinigen. Zu diesem Zweck ist es bekannt zwischen der Mischkammer und dem Rückschlagventil einen gesteuerten Druckwasseranschluß vorzusehen, der bei abgesperrter Zuleitung zu dem Wasserstrahlrohr zwecks Durchspülung geöffnet wird. Es ist auch möglich das Rückschlagventil mit dem Anschluß für Sirup und Konzentrat von dem Injektorgehäuse zu trennen und den Anschluß des Injektorgehäuses mit einer Spülleitung zu verbinden.It is necessary and usually usual to assign a check valve to the supply line for the syrup or concentrate. This is necessary in order to prevent water or the mixed drink from entering this supply line when faults occur. Such a check valve is also required to rinse and clean the mixing chamber and all parts of the system that are in contact with the mixed drink with water for hygienic reasons. For this purpose, it is known to provide a controlled pressure water connection between the mixing chamber and the check valve, which is opened for rinsing when the supply line to the water jet pipe is shut off. It is also possible to separate the check valve with the connection for syrup and concentrate from the injector housing and to connect the connection of the injector housing with a flushing line.

All diese Lösungen sind aufwendig und kompliziert und schwierig zu bedienen. Der hohe Bedienungsaufwand bietet das Risiko, daß nicht in ausreichend kurzen Abständen gespült wird, was zu hygienischen Problemen führen kann.All of these solutions are complex, complicated and difficult to use. The high level of operating effort entails the risk that washing is not carried out in sufficiently short intervals, which can lead to hygienic problems.

Es ist Aufgabe der Erfindung die aufgezeigten Nachteile zu vermeiden und eine Wasserstrahl-Injektionsvorrichtung mit den Merkmalen des Oberbegriffs so weiterzubilden, daß bei geringem Herstellungs- und Bedienungsaufwand eine einfache und zuverlässige Spülung gewährleistet ist.It is an object of the invention to avoid the disadvantages shown and to develop a water jet injection device with the features of the preamble in such a way that simple and reliable rinsing is ensured with little production and operating effort.

Diese Aufgabe wird durch die Maßnahmen des Anspruchs 1 gelöst.This object is achieved by the measures of claim 1.

Aufgrund der vorgesehenen Maßnahmen wird der durch das Wasserstrahlrohr zugeführte und die Injektionswirkung hervorrufende Wasserstrahl bei Bedarf zur Spülung der Mischkammer und aller mit dem Mischgetränk in Kontakt tretenden Teile der Injektionsvorrichtung ausgenutzt. Dies wird dadurch erreicht, daß bei Spülbedarf der Wasserstrahl so gestört wird, daß die Injektorwirkung umgekehrt wird und in der Mischkammer ein durch den Wasserstrahl hervorgerufener Druckanstieg erreicht wird. Durch die Störung des Wasserstrahls wird dieser zugleich zu einer turbulenten Strömung innerhalb der Mischkammer umgewandelt, wodurch die Spül- und Reinigungswirkung wesentlich begünstigt wird.On the basis of the measures provided, the water jet supplied through the water jet pipe and causing the injection action becomes, if necessary, for rinsing the mixing chamber and all that come into contact with the mixing drink Parts of the injection device used. This is achieved by disturbing the water jet when flushing is required so that the injector effect is reversed and a pressure rise caused by the water jet is achieved in the mixing chamber. Due to the disturbance of the water jet, this is also converted into a turbulent flow within the mixing chamber, whereby the rinsing and cleaning effect is significantly enhanced.

Ein besonderer Wasseranschluß für den Spülvorgang ist nicht erforderlich. Ebensowenig sind Handgriffe oder Steuerungsmaßnahmen zur Bedienung dieses besonderen Wasseranschlusses notwendig.A special water connection for the rinsing process is not necessary. Hand movements or control measures to operate this special water connection are also not necessary.

Durch die Einfachheit der Bedienung wird die ordnungsgemäße Spülung des Injektorsystems entscheidend begünstigt, so daß hygienische Probleme nicht zu befürchten sind.Due to the simplicity of operation, the proper flushing of the injector system is decisively promoted, so that hygienic problems are not to be feared.

Die Anordnung ist so einfach im Aufbau und in der Bedienung, so daß es auch möglich ist, eine Spülung des Systems automatisch als Schlußphase jedes Abgabevorganges für ein Mischgetränk vorzusehen. Unabhängig davon können auch am Dispenser schon vorhandene Betätigungselemente, die z.B. zum Auslösen des Abgabevorganges für das Mischgetränk dienen dazu verwendet werden, um in Abhängigkeit vom Ausgabevorgang des Mischgetränkes oder aber willkürlich den Spülvorgang auszulösen.The arrangement is so simple in structure and operation that it is also possible to automatically rinse the system as the final phase of each dispensing process for a mixed drink. Irrespective of this, existing actuating elements, e.g. to trigger the dispensing process for the mixed drink are used to trigger the rinsing process depending on the dispensing process of the mixed drink or arbitrarily.

Die Erfindung wird nachfolgend anhand einer schematischen Zeichnung eines Ausführungsbeispiels näher erläutert.The invention is explained in more detail below with the aid of a schematic drawing of an exemplary embodiment.

Die Figur zeigt einen Wasserstrahl-Injektionsvorrichtung gemäß der Erfindung im senkrechten Schnitt.The figure shows a water jet injection device according to the invention in vertical section.

Im dargestellten Beispiel weist die Wasserstrahl-Injektionsvorrichtung ein langgestrecktes, im vorliegenden Fall horizontal liegendes Injektorgehäuse 1 auf, das in einer Aufnahme 6 des Dispensers angeordnet ist und an seinem rückwärtigen Ende an eine Wasserdruckleitung anschließbar ist, während das vordere Ende einen Düsenabschnitt 4 aufweist, auf dem abgedichtet und schwenkbar ein Abgabestutzen 5 angeordnet ist. Hinter dem Düsenabschnitt 4 ist eine Mischkammer 8 vorgesehen, die nach rückwärts durchein Dichtelement 20 abgeschlossen ist, welches abdichtend auch das zentral entlang der Achse 9 des Injektorgehäuses 1 ausgerichtete Wasserstrahlrohr 3 umgibt. Das Dichtelement 20 schließt rückschlagartig bei fehlender Injektorwirkung die seitliche Anschlußleitung 7 für den Fruchtsirup oder das Konzentrat ab.In the example shown, the water jet injection device has an elongated, in the present case horizontal injector housing 1, which is arranged in a receptacle 6 of the dispenser and can be connected at its rear end to a water pressure line, while the front end has a nozzle section 4 which is sealed and pivoted a dispensing nozzle 5 is arranged. A mixing chamber 8 is provided behind the nozzle section 4, which is closed to the rear by a sealing element 20, which also sealingly seals it centrally along the axis 9 of the injector housing 1 surrounding water jet pipe 3. The sealing element 20 suddenly closes off the side connecting line 7 for the fruit syrup or the concentrate in the absence of an injector effect.

In der Wand des Injektorgehäuses 1 ist abgedichtet aber radial verschiebbar angeordnet ein Ablenk- oder Prallelement 19, das in der Figur in der Ruhestellung gezeigt ist und damit außerhalb der durch die Mischkammer 8 führenden Bahn des Wasserstrahls zwischen Wasserstrahlrohr 3 und Düsenabschnitt 4 liegt. Das Prallelement weist außerhalb des Injektorgehäuses 1 ein Betätigungselement 18 auf. Die Anordnung umfaßt (nicht dargestellt) ein Vorspannelement, das bestrebt ist, normalerweise das Prallelement 19 in der nicht wirksamen zurückgezogenen Stellung zu halten.In the wall of the injector housing 1, a deflecting or impact element 19 is sealed but radially displaceably arranged, which is shown in the figure in the rest position and thus lies outside the path of the water jet leading through the mixing chamber 8 between the water jet pipe 3 and the nozzle section 4. The impact element has an actuating element 18 outside the injector housing 1. The arrangement includes (not shown) a biasing element which tends to normally maintain the baffle 19 in the inactive retracted position.

In dem Spendergehäuse ist an einer von außen zugänglichen Stelle ein Betätigungselement im dargestellten Beispiel in Form eines Stößels 17 vorgesehen, der in einem Balg 16 axial beweglich und abgedichtet so angeordnet ist, daß beim Eindrükken des Stößels 17 das Betätigungselement 18 beaufschlagt und das Prallelement 19 in die Bahn des Wassestrahls bewegt wird.In the dispenser housing, an actuating element in the example shown is provided in the form of a plunger 17 at an externally accessible location, which is axially movable and sealed in a bellows 16 such that when the plunger 17 is pressed in, the actuating element 18 acts and the impact element 19 in the path of the water jet is moved.

Die Betätigung des Stößels 17 bzw. des Betätigungselementes 18 kann auf verschiedene Weise erfolgen. So .ist es möglich in dem Spender eine Betätigungsvorrichtung vorzusehen, die in Abhängigkeit von der Auslösung eines Abgabevorganges so in Wirkung gesetzt wird, daß in der letzten Phase des Abgabevor- ganges das Betätigungselement 18 beaufschlagt wird, so daß die Restwassermenge, die für das Mischgetränk benötigt wird, als Spülwasser ausgenutzt wird, indem in der letzten Phase des Abgabevorganges der Wasserstrahl in der Mischkammer 8 gestört wird, wodurch das rückschlagartige Dichtelement 20 den weiteren Zulauf von Fruchtsirup oder Konzentrat unterbindet und eine wirbelnde Spülströmung in der Mischkammer und dem Düsenabschnitt 4 und dem Auslaufstutzen 5 erzeugt wird.The plunger 17 or the actuating element 18 can be actuated in various ways. It is thus possible to provide an actuating device in the dispenser which, depending on the triggering of a dispensing process, is activated in such a way that the actuating element 18 is acted upon in the last phase of the dispensing process, so that the residual water quantity required for the mixed drink is used as rinsing water by disrupting the water jet in the mixing chamber 8 in the last phase of the dispensing process, as a result of which the non-return sealing element 20 prevents the further inflow of fruit syrup or concentrate and a swirling rinsing flow in the mixing chamber and the nozzle section 4 and the like Spout 5 is generated.

Im dargestellten Beispiel wird die Spülung des Injektorgehäuses willkürlich vorgenommen. Dazu wird vorteilhafterweise ein Betätigungselement wie ein Paddel 12 ausgenutzt, das an dem Gehäuse 10 des Dispenders bei 12a schwenkbar unter dem Auslaufstutzen 5 angeordnet ist. Dieses Paddel liegt normalerweise in der Einschubbahn eines Bechers in dem Ausgabebereich des Dispensers und dient normalerweise dazu den Misch- und Abgabevorgang auszulösen, wenn ein Becher ordnungsgemäß in den Dispenser eingeschoben ist. Diese Auslösebewegung des Paddels 12 ist durch den Pfeil 13 angedeutet. Dieses Paddel 12 ist so ausgebildet und angeordnet, daß es bei Bewegung entgegen der durch den Pfeil 13 angedeuteten Auslösebewegung, also bei Bewegung in Richtung des Pfeils 14 den Stößel 17 beaufschlagt um so den Spülvorgang in der beschriebenen Weise auszulösen.In the example shown, the injector housing is flushed arbitrarily. For this purpose, an actuating element, such as a paddle 12, is advantageously used, which is arranged on the housing 10 of the dispenser at 12a pivotably under the outlet connection 5. This paddle normally lies in the insertion path of a cup in the dispensing area of the dispenser and is normally used for the mixing and dispensing process trigger when a cup is properly inserted into the dispenser. This triggering movement of the paddle 12 is indicated by the arrow 13. This paddle 12 is designed and arranged such that it acts on the plunger 17 when moving against the triggering movement indicated by the arrow 13, that is to say when moving in the direction of the arrow 14, so as to trigger the rinsing process in the manner described.

Die beschriebene Vorrichtung arbeitet mit erhöhtem Wasserdruck, der vorzugsweise zwischen etwa 3,5 und 6 bar liegt. Bei diesem hohen Druck ergibt sich mit Hilfe der Ablenkeinrichtung eine hochwirksame Reinigung aller wichtigen Bereiche der Injektionsvorrichtung.The device described works with increased water pressure, which is preferably between about 3.5 and 6 bar. At this high pressure, the deflection device results in highly effective cleaning of all important areas of the injection device.

Es hat sich auch gezeigt, daß mit gesteuertem Eingriff in den in die Mischkammer einleitenden Wasserstrahl auch das Gemisch (Anteile von Wasser und zugemischtem Material) reguliert werden kann. Dazu kann eine Justiereinrichtung vorgesehen sein, mit der die Endstellung des Ablenkorgans vor dem Strahl eingestellt werden kann, wenn dies Organ während des Abgabevorganges in den Strahl vorbewegt wird. Die Stellung während des Spülvorganges kann davon unbeeinflußt bleiben.It has also been shown that the mixture (proportions of water and admixed material) can also be regulated by controlled intervention in the water jet leading into the mixing chamber. For this purpose, an adjusting device can be provided, with which the end position of the deflecting member in front of the jet can be adjusted if this member is moved into the jet during the dispensing process. The position during the rinsing process can remain unaffected.
