Description

Die Erfindung betrifft eine Vorrichtung zur Karbonisierung und Kühlung von Getränken, insbesondere von Trinkwasser, mit einem Getränkebehälter, in dem eine Karbonisiereinheit mit einem externen CO2-Anschluß untergebracht ist, und mit einer Kühleinrichtung.The invention relates to a device for carbonating and cooling of beverages, in particular of drinking water, with a beverage container in which a Karbonisiereinheit is housed with an external CO 2 connection, and with a cooling device.

Als Erfrischungsgetränke werden gerne gekühlte und karbonisierte, d.h. mit CO2 angereicherte Getränke konsumiert. Aus Platz- und Vorratshaltungsgründen ist es vorteilhaft, Getränke erst vor Ort und kurz vor dem Ausschenken mit CO2 anzureichern.As soft drinks cooled and carbonated, ie enriched with CO 2 drinks are consumed. For space and storage reasons, it is advantageous to enrich drinks only on site and shortly before serving with CO 2 .

Aus der DE 30 16 941 A1 ist ein Getränkeautomat mit einem zur Vorratshaltung, Kühlung und Karbonisierung von Trinkwasser dienendem Behälter bekannt. Zur Kühlung ist an der Außenseite des Behälters ein an ein Kälteaggregat angeschlossener Wärmetauscher vorgesehen. Zur Karbonisierung des Trinkwasservorrates dient ein CO2-Gaspolster oberhalb des Trinkwasserspiegels im Behälter. Die Ausstoßmenge an gekühltem, karbonisiertem Wasser ist bei dem beschriebenen Automat jedoch niedrig.From DE 30 16 941 A1 a vending machine with a serving for stockpiling, cooling and carbonation of drinking water container is known. For cooling, a heat exchanger connected to a refrigeration unit is provided on the outside of the container. To carbonize the drinking water supply, a CO 2 gas cushion is used above the drinking water level in the container. However, the discharge amount of cooled carbonated water is low in the described automaton.

Ein anderer Getränkeautomat mit einem zur Vorratshaltung, Kühlung und Karbonisierung von Trinkwasser dienendem Behälter ist in der DE 80 12 782 U1 beschrieben. Die Kühlung erfolgt wieder über einen an ein Kälteaggregat abgeschlossenen Wärmetauscher an der Außenseite des Behälters. Zur Karbonisierung ist hier ein am Behälterboden befindlicher scheibenförmiger Verteiler vorgesehen, der für eine gute Diffusion des von außen unter Druck zugeführten CO2 sorgt. Auch bei diesem Getränkeautomaten muß das eingefüllte Trinkwasser zunächst eine bestimmte Zeit lang gekühlt und mit CO2 durchsprudelt werden, bevor ein Ausschank des fertigen Getränkes erfolgen kann.Another vending machine with a serving for stockpiling, cooling and carbonation of drinking water container is described in DE 80 12 782 U1. The cooling takes place again via a closed to a refrigeration unit heat exchanger on the outside of the container. For carbonation, a disk-shaped distributor located at the bottom of the container is provided here, which ensures good diffusion from outside pressurized CO 2 provides. Also in this vending machines, the filled drinking water must first be cooled for a certain time and bubbled with CO 2 , before a serving of the finished beverage can be done.

Eine Aufgabe der Erfindung besteht darin, eine Vorrichtung zur Karbonisierung und Kühlung von Getränken anzugeben, mit der bei geringem Platzbedarf größere Getränkemengen erzeugt werden können.An object of the invention is to provide a device for the carbonation and cooling of beverages, with the larger quantities of drinks can be produced in a small footprint.

Die Aufgabe wird gelöst durch eine Vorrichtung zur Karbonisierung und Kühlung von Getränken nach Anspruch 1. Vorteilhafte Ausgestaltungen sind den abhängigen Ansprüchen zu entnehmen.The object is achieved by a device for carbonation and cooling of beverages according to claim 1. Advantageous embodiments can be found in the dependent claims.

Die Vorrichtung zur Karbonisierung und Kühlung von Getränken, insbesondere von Trinkwasser, weist eine Kühleinrichtung und einen Getränkebehälter auf, in dem eine Karbonisiereinheit mit einem externen CO2-Anschluß untergebracht ist. Erfindungsgemäß ist die Karbonisiereinheit in einem rohrförmigen Innenbehälter angeordnet, der sich im Inneren des Getränkebehälters befindet und an einem ersten Ende eine Entnahmeleitung für karbonisiertes Getränk und an einem zweiten Ende eine Verbindung zu dem äußeren Getränkebehälter aufweist. Außerdem enthält die Karbonisiereinheit eine Vielzahl von Hohlvolumina, die über den externen CO2-Anschluß mit CO2 beaufschlagt werden und von einer für CO2-Gas durchlässigen aber wasserundurchlässigen Membran von dem Getränk im Inneren des Innenbehälters abgetrennt sind.The device for the carbonation and cooling of beverages, in particular of drinking water, has a cooling device and a beverage container, in which a Karbonisiereinheit is housed with an external CO 2 connection. According to the invention, the carbonating unit is arranged in a tubular inner container which is located inside the beverage container and has a carbonated beverage removal line at a first end and a connection to the outer beverage container at a second end. In addition, the Karbonisiereinheit contains a plurality of hollow volumes, which are acted upon via the external CO 2 connection with CO 2 and separated from a permeable for CO 2 gas but water-impermeable membrane of the beverage in the interior of the inner container.

Diese Anordnung gestattet es, größere Mengen an Getränk zu karbonisieren und kann im Durchfluß betrieben werden. Indem die Karbonisiereinheit in einem Innenbehälter angeordnet ist, in den nur vorgekühltes Getränk aus dem äußeren Getränkebehälter gelangt, wird das Getränk sehr schnell mit CO2 angereichert.This arrangement makes it possible to carbonize larger quantities of beverage and can be operated in the flow. By the carbonating unit in an inner container is arranged, passes in the only pre-cooled beverage from the outer beverage container, the beverage is very quickly enriched with CO 2 .

Vorzugsweise ist der Innenbehälter derart in dem Getränkebehälter angeordnet, daß er konzentrisch von gekühltem aber noch nicht karbonisiertem Getränk umgeben wird. Dies ermöglicht beste Kühlung im Inneren.Preferably, the inner container is disposed in the beverage container such that it is concentrically surrounded by cooled but not yet carbonated beverage. This allows best cooling inside.

Bei den Hohlvolumina handelt es sich vorzugsweise um die Innenräume von Hohlfasermembranen. Diese weisen eine große Membranoberfläche auf und ermöglichen daher eine besonders schnelle und gründliche Anreicherung des Getränkes mit CO2.The hollow volumes are preferably the interiors of hollow fiber membranes. These have a large membrane surface and therefore allow a particularly rapid and thorough enrichment of the beverage with CO 2 .

Gemäß einer vorteilhaften Weiterbildung ist in der Verbindung zwischen äußerem Getränkebehälter und Innenbehälter ein Silberfilter zur Desinfektion des Getränks vorgesehen. Dadurch wird die Qualität des Getränks verbessert, was besonders bei der Verwendung gewöhnlichen Leitungswassers Vorteile bietet.According to an advantageous development, a silver filter for disinfecting the beverage is provided in the connection between the outer beverage container and the inner container. This improves the quality of the drink, which offers advantages especially when using ordinary tap water.

Vorzugsweise ist bei dieser Weiterbildung an einer Getränkezuleitung und an der Entnahmeleitung jeweils ein Druckmesser zur Bestimmung eines Differenzdrucks zwischen zugeleitetem und entnommenem Getränk vorgesehen. Eine Anzeigeeinrichtung dient zur Anzeige des aus dem Differenzdruck ermittelten Filterzustandes. So kann der Filterzustand auf einfache Weise überwacht und der Filter rechtzeitig ausgetauscht oder gereinigt werden.In this development, a pressure gauge for determining a differential pressure between supplied and withdrawn drink is preferably provided in each case at a beverage supply line and at the withdrawal line. A display device serves to display the filter state determined from the differential pressure. Thus, the filter condition can be easily monitored and the filter replaced or cleaned in a timely manner.

Die Kühleinrichtung enthält vorteilhaft ein thermo-elektrisches Kühlelement. Ein solches Kühlelement kühlt besonders effektiv und weist auch bei größeren Entnahmemengen eine gute Kühlleistung auf. Da auf ein Kühlmittelaggregat verzichtet werden kann, ist die Vorrichtung besonders kompakt aufgebaut. Außerdem ermöglicht sie einen sehr leisen Betrieb.The cooling device advantageously contains a thermoelectric cooling element. Such a cooling element cools particularly effectively and has a good cooling performance even with larger removal quantities. There on one Coolant unit can be omitted, the device is particularly compact. It also allows very quiet operation.

Zweckmäßig ist mit dem thermo-elektrischen Kühlelement ein Kühlkörper thermisch verbunden und ein Lüfter vorgesehen, der den Kühlkörper kühlt. Durch die effiziente Wärmeabfuhr wird die Kühlleistung verbessert und die Vorrichtung kann noch kompakter ausgeführt werden.Appropriately, a heat sink is thermally connected to the thermo-electric cooling element and a fan is provided which cools the heat sink. The efficient heat dissipation improves the cooling performance and makes the device even more compact.

Vorteilhaft ist die Kühleinrichtung an einer Außenseite des Getränkebehälters angeflanscht.

FIG. 2:
a cross section through the Karbonisiereinheit of Figure 1.

Die in Figur 1 im Längsschnitt gezeigte Vorrichtung 10 zur Kühlung und Karbonisierung von Getränken besitzt einen Getränkebehälter 11 mit einer thermischen Isolierschicht 22. Über eine Zuleitung 18 wird der Getränkebehälter 11 mit frischem Getränk, vorzugsweise Wasser, befüllt. An der Zuleitung ist ein Druckregler 32 angeordnet. Die Zuleitung kann z.B. mit dem Trinkwassernetz oder auch mit einem Wassertank verbunden sein. In den Getränkebehälter 11 ist ein rohrförmiger Innenbehälter 12 eingesetzt, der an seinem unteren Ende mit dem äußeren Getränkebehälter 11 verbunden ist. Die Vorrichtung wird durch vier Spannschrauben 26 zusammengehalten. In dem Boden 23 des Getränkebehälters ist ein Kanal 24 vorhanden, der mit dem Innenbehälter 12 und seitlich über eine Schrägbohrung 25a mit dem äußeren Getränkebehälter 12 verbunden ist. In dem Kanal befindet sich ein Silberfilter 27 zur Desinfektion des Getränks.The apparatus 10 for cooling and carbonating beverages shown in FIG. 1 in longitudinal section has a beverage container 11 with a thermal insulating layer 22. Via a supply line 18, the beverage container 11 is filled with fresh drink, preferably water. At the supply line, a pressure regulator 32 is arranged. The supply line may e.g. be connected to the drinking water network or with a water tank. In the beverage container 11, a tubular inner container 12 is used, which is connected at its lower end to the outer beverage container 11. The device is held together by four clamping screws 26. In the bottom 23 of the beverage container, a channel 24 is present, which is connected to the inner container 12 and laterally via an oblique bore 25 a with the outer beverage container 12. In the channel is a silver filter 27 for disinfecting the drink.

In den Innenbehälter ist eine austauschbare Karbonisiereinheit 13 eingesetzt. Über eine CO2-Zuleitung 15 mit Druckregler 33 wird die Karbonisiereinheit 13 mit CO2 versorgt. In den Innenbehälter 12 mündet eine Entnahmeleitung 16 zur Entnahme karbonisierten Getränks. An der Entnahmeleitung 16 ist ein elektrisches 2/2-WegeVentil 30 vorgesehen. An dem Getränkebehälter 11 ist seitlich des Innenbehälters 12 zusätzlich noch ein zweiter Leitungsanschluß 17 zur Entnahme von unkarbonisiertem, gekühltem Getränk vorgesehen, der auch mit einem elektrisches 2/2-Wege-Ventil 31 versehen ist. Die Entnahmeleitung 17 ist über eine Schrägbohrung 25a mit dem Kanal 24 im Boden 23 des Getränkebehälters 11 verbunden. An der Mündung der Schrägbohrung befindet sich ein weiterer Silberfilter 27b. Der Boden 23 kann zum Austausch der Karbonisiereinheit 13 und zum Wechseln oder Reinigen der Silberfilter 27, 27b geöffnet werden.In the inner container, an exchangeable Karbonisiereinheit 13 is inserted. Via a CO 2 supply line 15 with pressure regulator 33, the carbonating unit 13 is supplied with CO 2 . Into the inner container 12 opens a sampling line 16 for the removal of carbonated beverage. At the extraction line 16, an electrical 2/2-way valve 30 is provided. On the beverage container 11, a second line connection 17 for removing uncarbonated, cooled beverage is additionally provided laterally of the inner container 12, which is also provided with an electric 2/2-way valve 31. The removal line 17 is connected via an inclined bore 25 a to the channel 24 in the bottom 23 of the beverage container 11. At the mouth of the oblique bore is a another silver filter 27b. The bottom 23 may be opened to replace the carbonating unit 13 and to change or clean the silver filters 27, 27b.

An der in Figur 1 linken Seitenwand des Getränkebehälters 11 ist ein thermo-elektrisches Kühlelement 14 angeflanscht. Thermo-elektrische Kühlelemente sind an sich bekannt und arbeiten nach dem Peltier-Effekt, indem durch einen elektrischen Stromfluß eine Seite des Kühlelementes sich abkühlt, während die andere sich erwärmt. Solche Peltier-Kühler werden für eine Vielzahl von Anwendungen verwendet. An der warmen Seite des Kühlelements 14 ist ein Kühlkörper 20 thermisch angekoppelt, der von einem Lüfter 20 mit Luft gekühlt wird. Eine elektrische Steuerung 19 steuert Kühlelement 14 und Lüfter 20 um eine konstante niedrige Temperatur in dem Getränkebehälter 11 zu gewährleisten. Zur thermischen Ankopplung besteht die Seitenwand des Getränkebehälters 11 aus Messing.On the left in Figure 1 side wall of the beverage container 11, a thermo-electric cooling element 14 is flanged. Thermo-electric cooling elements are known per se and work according to the Peltier effect by one side of the cooling element cools by an electric current flow, while the other is heated. Such Peltier coolers are used for a variety of applications. On the warm side of the cooling element 14, a heat sink 20 is thermally coupled, which is cooled by a fan 20 with air. An electrical control 19 controls cooling element 14 and fan 20 to ensure a constant low temperature in the beverage container 11. For thermal coupling, the side wall of the beverage container 11 is made of brass.

Die Karbonisiereinheit enthält eine Vielzahl von sogenannten Hohlfasermembranen. Die hohlen Fasern bestehen aus einer semipermeablen Membran aus Polymer oder keramischem Werkstoff. Gase können durch die Membran hindurch diffundieren, während Flüssigkeiten zurückgehalten werden. Die Hohlfasermembranen werden im Inneren über die CO2-Zuleitung 15 und den Druckregler 33 unter konstantem Druck mit CO2-Gas beaufschlagt. Das CO2 diffundiert durch die Hohlfasermembranen in den rohrförmigen Innenbehälter 12 und löst sich in dem darin befindlichen Getränk. Durch die große Oberfläche der vielen Hohlfasermembranen wird das Getränk sehr schnell mit CO2 angereichert. Die Karbonisiereinheit 13 kann mit geringem CO2-Druck betrieben werden. Da die Löslichkeit von CO2 unter Druck höher ist, schäumen unter Druck karbonisierte Getränke beim Entnehmen stark auf. Dies wird durch die Verwendung des Hohlfasermembran-Karbonisierers, der mit geringem Druck betrieben werden kann, weitgehend verhindern.The carbonating unit contains a plurality of so-called hollow fiber membranes. The hollow fibers consist of a semipermeable membrane of polymer or ceramic material. Gases can diffuse through the membrane while retaining liquids. The hollow fiber membranes are acted upon in the interior via the CO 2 supply line 15 and the pressure regulator 33 under constant pressure with CO 2 gas. The CO 2 diffuses through the hollow fiber membranes into the tubular inner container 12 and dissolves in the beverage therein. Due to the large surface area of the many hollow-fiber membranes, the beverage is very quickly enriched with CO 2 . The carbonating unit 13 can be operated with low CO 2 pressure. As the solubility of CO 2 under pressure is higher, under pressure carbonated beverages foam heavily on removal. this will by the use of the hollow fiber membrane carbonator, which can be operated at low pressure, largely prevent.

Über die Zuleitung 18 wird wie eben schon erwähnt frisches Getränk zugeführt. Dies kann beispielsweise Trinkwasser aus einer an die Zuleitung angeschlossenen Trinkwasserleitung sein. Durch das Kühlelement 14 wird das Getränk im Vorbeiströmen gekühlt. Erst das auf diese Weise gekühlte Getränk gelangt über die Verbindungsleitung 121 mit dem Silberfilter 27 in den Innenbehälter 12. Dadurch ist das Getränk gut vorgekühlt, bevor es in die Karbonisiereinheit 13 im Inneren des Innenbehälters 12 gelangt. Da die Löslichkeit von CO2 in kaltem Wasser höher ist, ist die Anreicherung durch diesen Aufbau gegenüber herkömmlichen Geräten verbessert.About the supply line 18 as already mentioned fresh drink supplied. This can be, for example, drinking water from a drinking water line connected to the supply line. By the cooling element 14, the beverage is cooled in the Vorbeiströmen. Only the drink cooled in this way passes via the connecting line 121 with the silver filter 27 into the inner container 12. As a result, the beverage is well pre-cooled before it enters the carbonating unit 13 in the interior of the inner container 12. Since the solubility of CO 2 in cold water is higher, the enrichment is improved by this structure over conventional devices.

Der Silberfilter 27 dient dazu, im zugeführten Wasser enthaltene Keime abzutöten. Er besteht aus einem feinmaschigen Silber- oder silberbeschichteten Gewebe. Grobe Partikel, wie mitgeschwemmte Kalkrückstände aus der Wasserzuleitung, werden in dem Silberfilter 27 ebenfalls zurückgehalten. Der Silberfilter 27 kann sich daher nach einiger Zeit zusetzen. Daher ist eine Anzeigeeinrichtung (nicht gezeigt) zur Anzeige des Filterzustandes vorgesehen. Dazu befindet sich in der Zuleitung 18 und in der Entnahmeleitung 16 jeweils ein Druckmesser, mit deren Hilfe der Differenzdruck zwischen zugeleitetem und entnommenem Getränk bestimmt wird. Je schlechter der Silberfilter 27 durchgängig ist, um so höher ist der Differenzdruck. Übersteigt der Differenzdruck eine tolerable Schwelle, so wird angezeigt, daß der Silberfilter ersetzt oder gereinigt werden muß. Reinigung oder Austausch des Silberfilters 27 kann dann über den Boden 23 vorgenommen werden.The silver filter 27 serves to kill germs contained in the supplied water. It consists of a fine-meshed silver or silver-coated fabric. Coarse particles, such as washed-out limescale from the water supply, are also retained in the silver filter 27. The silver filter 27 can therefore clog after some time. Therefore, a display device (not shown) for displaying the filter state is provided. For this purpose, in the supply line 18 and in the extraction line 16 are each a pressure gauge, by means of which the differential pressure between supplied and withdrawn drink is determined. The worse the silver filter 27 is continuous, the higher the differential pressure. If the differential pressure exceeds a tolerable threshold, it is indicated that the silver filter must be replaced or cleaned. Cleaning or replacement of the silver filter 27 can then be done via the bottom 23.

Die Vorrichtung 10 ist in Figur 2 in einem Querschnitt gezeigt. Der Getränkebehälter 11 der Vorrichtung 10 weist ein quadratisches Profil auf. Der konzentrisch in dem Getränkebehälter 11 angeordnete Innenbehälter 12 hat hingegen ein rundes Profil. In dem Innenbehälter 12 ist die Karbonisiereinheit 13 mit Hohlfasermembranen eingesetzt. Selbstverständlich können der Innenbehälter 12, der Außenbehälter 11 und entsprechend auch die Karbonisiereinheit 13 auch ein beliebiges anderes Profil haben.The device 10 is shown in Figure 2 in a cross section. The beverage container 11 of the device 10 has a square profile. The concentric arranged in the beverage container 11 inner container 12, however, has a round profile. In the inner container 12, the carbonating unit 13 is inserted with hollow fiber membranes. Of course, the inner container 12, the outer container 11 and accordingly also the Karbonisiereinheit 13 also have any other profile.

In der rechten unteren Ecke des Getränkebehälters 11 ist der Leitungsanschluß 17 zur Entnahme von unkarbonisiertem, gekühltem Getränk gezeigt, der über den Silberfilter 25 (nicht gezeigt) mit dem Getränkebehälter 11 verbunden ist. Mit langen Spannschrauben 26 wird die Vorrichtung 10 zusammengehalten.In the lower right corner of the beverage container 11, the line connection 17 for the removal of uncarbonated, cooled beverage is shown, which is connected via the silver filter 25 (not shown) to the beverage container 11. With long clamping screws 26, the device 10 is held together.

Seitlich ist an den Getränkebehälter 11 der Peltier-Kühler 14 mit Schrauben 28 angeflanscht. Der Kühlkörper 20 ist mit Schrauben 29 auf dem Peltier-Kühler 14 festgeschraubt. Zwei Lüfter 21 kühlen den Kühlkörper 20 mit Luft. Die ganze Vorrichtung ist in einem stabilen, kompakten Gehäuse 34 mit rechteckigem Profil aus Stahlblech untergebracht.The side of the beverage container 11 of the Peltier cooler 14 is flanged with screws 28. The heat sink 20 is screwed with screws 29 on the Peltier cooler 14. Two fans 21 cool the heat sink 20 with air. The whole device is housed in a stable, compact housing 34 with a rectangular profile made of sheet steel.
