Description

Die Erfindung betrifft eine Vorrichtung zum Erzeugen von kohensäurehaltigem Wasser mit einem wasserdurchströmbaren Behälter und einer in den Behälter mündenden Kohlensäure-Zuführung.The invention relates to a device for producing carbonated Water with a water flowable container and one in the container mouthful carbonic acid feed.

Bei einer bekannten Vorrichtung der oben angegebenen Art wird Wasser zur Erzeugung eines Getränkes mit Kohlensäure versetzt. Dabei wird das Wasser in einem Behälter mittelst einer Düse eingebracht. In den Behälter wird zusätzlich CO2 eingeleitet. Das CO2 kann sich in dem Behälter im Wasser lösen. Das aus dem Behälter heraussströmende Wasser ist dann carbonisiert. Dieses carbonisierte Wasser kann direkt als Getränk verwendet werden. Es ist aber auch vorgesehen, dass dem carbonisierten Wasser ein Getränkekonzentrat zugesetzt wird. Alternativ kann Wasser dadurch carbonisiert werden, dass es in einer CO2-Atmosphäre zerstäubt wird. Bei der Zerstäubung des Wasser diffundiert CO2 in die Wassertröpfchen. Auf diese Weise bildet sich dann carbonisiertes Wasser (Sodawasser). Der Sättigungsgrad des Wassers mit CO2 hängt in erheblichem Maße vom CO2-Druck und der Temperatur des eingespritzten Wassers ab.In a known device of the type specified above, water is carbonated to produce a beverage. The water is introduced into a container by means of a nozzle. CO 2 is additionally introduced into the container. The CO 2 can dissolve in the container in the water. The water flowing out of the container is then carbonized. This carbonated water can be used directly as a drink. However, it is also provided that a beverage concentrate is added to the carbonated water. Alternatively, water can be carbonized by atomizing it in a CO 2 atmosphere. When the water is atomized, CO 2 diffuses into the water droplets. In this way carbonized water (soda water) is formed. The degree of saturation of the water with CO 2 depends to a large extent on the CO 2 pressure and the temperature of the water injected.

Der Erfindung liegt die Aufgabe zugrunde, eine gattungsgemäße Vorrichtung zu verbessern.The invention has for its object a generic device to improve.

Gelöst wird die Aufgabe durch die in den Ansprüchen angegebene Erfindung.The object is achieved by the invention specified in the claims.

Der Amspruch 1 sieht insbesondere vor, dass die CO2-Zuleitung dem Bodenbereich des Behälters zugeordnet ist. Der Kopfbereich des Behälters weist eine CO2-Ableitung auf, zur Entnahme von nicht im Wasser gelösten CO2. Dieses CO2 wird durch die CO2-Zuführung im Bodenbereich in das Wasser geleitet. Zufolge der erfindungsgemäßen Ausgestaltung können erhebliche Mengen von CO2 in den mit Wasser teilgefüllten Behälter eingebracht werden. Überschüssiges CO2 wird im Kopfbereich des Behälters abgesaugt und der CO2-Zuführung wieder zugeführt. In einer bevorzugten Weiterbildung der Erfindung liegt zwischen der CO2-Ableitung des Kopfes des Behälters und der CO2-Zuführung des Bodens des Behälters ein Gasverdichter. Mit diesem Gasverdichter kann das sich im Kopfbereich des Behälters ansammelnde CO2 abgesaugt werden. Zufolge dieses Absaugens ändert sich der Wasserspiegel des sich in dem Behälter befindenden Wassers. Um den Wasserspiegel auf einem bestimmten Niveau zu halten, besitzt der Behälter zwei Pegelsensoren. Ein Pegelsensor spricht an, wenn der Wasserspiegel einen Minimalpegel unterschreitet. Der andere Sensor spricht an, wenn der Wasserspiegel einen Maximalpegel überschreitet. Die Zuführung des Wassers erfolgt über den Kopf des Behälters. Der Wasserablauf erfolgt über den Boden des Behälters. In einer bevorzugten Ausgestaltung wird die Kohlensäure-Zuführung von einem porösen Hohlkörper ausgebildet. Bei diesem porösen Hohlkörper kann es sich um eine Filterpatrone aus Keramik oder Kunststoff handeln. Die Porösität dieses Hohlkörpers liegt vorzugsweise zwischen 20 und 60µm. Die Kohlensäurezufuhr kann kontinuierlich erfolgen. Es ist aber auch vorgesehen, diese intervallartig zuzuführen. In einer Weiterbildung der Erfindung sind zwei oder mehrere Behälter aneinandergereiht. Diese Behälter können als kommunizierende Röhren ausgestaltet sein. Bevorzugt sind Wasserzulauf und Pegelsensoren in voneinander verschiedenen Behältern angeordnet. Dies hat zur Folge, dass der Wasserspiegel im Bereich der Pegelsensoren nicht durch zulaufendes Wasser gestört wird, was zu einer Verfälschung der Pegelmesswerte führen könnte. Das von der Gaspumpe aus dem Kopfbereich des Behälters abgesaugte CO2 wird im Bereich des Behälterbodens in die Speiseleitung zurückgeführt. Die Speiseleitung mündet in den porösen Hohlkörper, der am Behälterboden befestigt ist. Durch die Wände des porösen Hohlkörpers gelangt das CO2 aus dem Hohlkörper und steigt in Form mikroskopischer Blasen im Wasser nach oben. Es wird dabei teilweise in Wasser gelöst. Das überschüssige CO2 sammelt sich im Kopfbereich des Behälters, um in der beschriebenen Weise abgesaugt und rückgeführt zu werden.Claim 1 provides in particular that the CO 2 feed line is assigned to the bottom region of the container. The head area of the container has a CO 2 drain for the removal of CO 2 not dissolved in the water. This CO 2 is led into the water through the CO 2 supply in the bottom area. As a result of the configuration according to the invention, considerable amounts of CO 2 can be introduced into the container which is partially filled with water. Excess CO 2 is sucked off in the head area of the container and returned to the CO 2 supply. In a preferred development of the invention, a gas compressor lies between the CO 2 discharge of the head of the container and the CO 2 supply of the bottom of the container. With this gas compressor, the CO 2 accumulating in the head area of the container can be extracted. As a result of this suction, the water level of the water in the container changes. The tank has two level sensors to keep the water level at a certain level. A level sensor responds when the water level falls below a minimum level. The other sensor responds when the water level exceeds a maximum level. The water is supplied via the top of the container. The water is drained from the bottom of the tank. In a preferred embodiment, the carbonic acid supply is formed by a porous hollow body. This porous hollow body can be a filter cartridge made of ceramic or plastic. The porosity of this hollow body is preferably between 20 and 60 µm. The carbonic acid can be supplied continuously. However, it is also envisaged to supply them at intervals. In a development of the invention, two or more containers are strung together. These containers can be designed as communicating tubes. The water inlet and level sensors are preferably arranged in different containers. The consequence of this is that the water level in the area of the level sensors is not disturbed by incoming water, which could lead to a falsification of the level measurement values. The CO 2 sucked out of the head region of the container by the gas pump is returned to the feed line in the region of the container bottom. The feed line opens into the porous hollow body, which is attached to the bottom of the container. The CO 2 comes out of the hollow body through the walls of the porous hollow body and rises in the form of microscopic bubbles in the water. It is partially dissolved in water. The excess CO 2 collects in the head region of the container in order to be suctioned off and returned in the manner described.

Der grundsätzliche Aufbau der erfindungsgemäßen Vorrichtung wird anhand der Fig. 1 beschrieben. Der Behälter 1 besitzt eine zylinderförmige Gestalt, wobei sich die Zylinderachse in der Vertikalen erstreckt. Die vertikale Länge des Behälters (Höhe) beträgt hier mindestens 400mm. Im Zentrum des Bodens 3 des Behälters 1 befindet sich die Mündung eines CO2-Kanals 15. Der CO2-Kanal 15 mündet in eine CO2-Zuführung, die die Form eines porösen Körpers 2 besitzt. Der poröse Körper 2 besitzt die Gestalt eines stirnseitig geschlossenen Rohres. Durch die Poren des porösen Körpers 2 kann das in die Höhlung des Körpers 2 einströmende CO2 aus dem Hohlkörper 2 heraustreten. Die Porengröße beträgt etwa 20 bis 60µm.The basic structure of the device according to the invention is described with reference to FIG. 1. The container 1 has a cylindrical shape, the cylinder axis extending in the vertical. The vertical length of the container (height) is at least 400mm. The mouth of a CO 2 channel 15 is located in the center of the bottom 3 of the container 1. The CO 2 channel 15 opens into a CO 2 feed, which has the shape of a porous body 2. The porous body 2 has the shape of a tube closed at the end. The CO 2 flowing into the cavity of the body 2 can emerge from the hollow body 2 through the pores of the porous body 2. The pore size is approximately 20 to 60 µm.

Im Bereich des Behälterkopfes 4 befindet sich eine Wasserzuleitung 11. Diese bildet eine Düse aus, durch welche das Wasser in den Behälter 1 einströmen kann. Am Boden 3 des Behälters 1 befindet sich ein Wasserablauf 12. Durch diesen Wasserablauf 12 wird das mit CO2 angereicherte Wasser einer nicht gezeichneten Ausgabevorrichtung in Form einer Tülle zugeleitet. In the area of the container head 4 there is a water supply line 11. This forms a nozzle through which the water can flow into the container 1. At the bottom 3 of the container 1 there is a water drain 12. Through this water drain 12, the water enriched with CO 2 is fed to an output device, not shown, in the form of a spout.

Die Steuerung des Wasserzulaufs in den Kopfbereich 1" des Behälters 1 erfolgt mittels eines Magnetventils 17.The control of the water supply in the head area 1 "of the container 1 is carried out by means of a solenoid valve 17.

Im Kopfbereich 1" des Behälters 1 befinden sich darüber hinaus zwei Pegelsensoren 7, 8. Mit dem Pegelsensor 7 wird der Maximalpegel des Wasserspiegels 9 detektiert. Mit dem Pegelsensor 8 wird der Minimalwert des Wasserspiegels 9 detektiert. Mittelst einer nicht dargestellten Regelung, der die Signale der Sensoren 7, 8 zugeführt werden, kann ein Gasverdichter 6 gesteuert werden. Dieser Gasverdichter 6 saugt mittels einer CO2-Ableitung 5 CO2 aus dem Kopfbereich 1" des Behälters 1. Hierdurch verbleibt ein nahezu konstantes CO2-Volumen 10 oberhalb des Wasserspiegels 9. Das durch die CO2-Ableitung 5 mittelst der Pumpe 6 abgesaugte CO2 wird durch einen CO2-Kanal 25 einer CO2-Einspeiseleitung 15 zugeführt, die in die CO2-Zuführung 2 mündet. In die CO2-Speiseleitung 15 mündet darüber hinaus eine CO2-Zuleitung von einer CO2-Flasche oder dergleichen. Zwischen dieser und der Einspeiseleitung 15 ist ein Rückschlagventil 16 geschaltet, um zu verhindert, dass der Gasverdichter 6 CO2 in Richtung der Vorratsflasche fördert.In the head region 1 "of the container 1 there are also two level sensors 7, 8. The level sensor 7 detects the maximum level of the water level 9. The level sensor 8 detects the minimum value of the water level 9. By means of a control (not shown) which detects the signals of the sensors 7, 8, a gas compressor 6 can be controlled. This gas compressor 6 sucks CO 2 from the head region 1 "of the container 1 by means of a CO 2 discharge 5. As a result, an almost constant CO 2 volume 10 remains above the water level 9. the through the CO 2 5 dissipation by means of the pump 6 sucked CO 2 is fed to 2 -Einspeiseleitung 15 by a CO 2 passage 25 a CO, which opens into the CO 2 supply. 2 In addition, a CO 2 feed from a CO 2 bottle or the like opens into the CO 2 feed line 15. A check valve 16 is connected between this and the feed line 15 in order to prevent the gas compressor 6 from conveying CO 2 in the direction of the storage bottle.

Das in den Figuren 2 und 3 dargestellte Ausführungsbeispiel zeigt eine Vorrichtung, die dieselben Elemente aufweist, die unter Bezugnahme auf die Fig. 1 vorstehend erörtert wurden. Zusätzlich weist diese Vorrichtung einen zweiten Behälter 14 auf. Dieser Behälter 14 ist mit dem Behälter 1 derartig verbunden, das beide Behälter miteinander kommunizieren und einen gemeinsamen Wasserspiegel 9 aufweisen. Hierzu dient zum einen der in Fig. 3 mit der Bezugsziffer 23 bezeichnete Wasserableitungskanal 23 sowie weitere, nicht dargestellte Kanäle. Zufolge des zweiten Behälters reduziert sich insgesamt die Bauhöhe.The embodiment shown in Figures 2 and 3 shows a device which has the same elements as described with reference to FIG. 1 were discussed above. In addition, this device has a second Container 14 on. This container 14 is connected to the container 1 in such a way that both containers communicate with each other and a common water level 9 have. For this purpose, the one with the reference number in FIG. 3 is used 23 designated water drainage channel 23 and other, not shown Channels. As a result of the second container, the overall height is reduced.

Die CO2-Ableitung erfolgt über die beiden Öffnungen 5 im Bereich des Kopfes 4 des Behälters. Diese beiden Öffnungen 5 sind über einen CO2-Kanal 24 miteinander verbunden. Der CO2-Kanal 24 befindet sich saugseitig der Pumpe 6. Durch einen CO2-Rückführungskanal 25 wird das von der Pumpe 6 verdichtete CO2 den beiden CO2-Zuführungen zugeführt. Jeder Behälter 1, 14 besitzt bodenseitig 1", 14" eine CO2-Zuführung. Jedoch besitzt nur der Behälter 14 einen Wasserzulauf in Form einer Düse. Der andere Behälter 1 besitzt die beiden Sensoren 7, 8.The CO 2 discharge takes place via the two openings 5 in the area of the head 4 of the container. These two openings 5 are connected to one another via a CO 2 channel 24. The CO 2 passage 24 is located on the suction side of the pump 6. By means of a CO 2 -Rückführungskanal 25, the air compressed by the pump 6, CO 2 is the two CO 2 fed to injection account. Each container 1, 14 has a CO 2 supply on the bottom side 1 ", 14". However, only the container 14 has a water inlet in the form of a nozzle. The other container 1 has the two sensors 7, 8.

Das Rückschlagventil 16 in der CO2-Einspeiseleitung ist in dem aus Metall oder Kunststoff bestehenden Vorrichtungsgehäuse integriert. Ebenfalls in das Gehäuse integriert ist ein Rückschlagventil 26 für die Wasserzuleitung.The check valve 16 in the CO 2 feed line is integrated in the device housing made of metal or plastic. A check valve 26 for the water supply line is also integrated into the housing.

In Strömungsrichtung unmittelbar vor dem Rückschlagventil 26 befindet sich das Magnetventil 17. Bei dem Magnetventil handelt es sich um ein Pellet-Ventil. Auf einem Ventilsitz 18 sitzt ein zylindrischer Ventilkegel 19. An dem Ventilkegel 19 greift ein Hebel 21 an, der um ein Lager 22 schwenkbar ist. Am Kraftarm des Hebels 21 greift ein Elektromagnet 20 an, um bei einer Bestromung den Ventilkegel 19 vom Ventilsitz abzuheben. Mittels einer Feder wird der Ventilkegel 19 ansonsten auf den Ventilsitz 18 gedrückt.Located in the direction of flow immediately before the check valve 26 the solenoid valve 17. The solenoid valve is a pellet valve. A cylindrical valve cone 19 sits on a valve seat 18. On the valve cone 19 engages a lever 21 which is pivotable about a bearing 22. On the power arm the lever 21 engages an electromagnet 20 in order to energize the Lift valve plug 19 off the valve seat. The valve cone is held by a spring 19 otherwise pressed onto the valve seat 18.

Die Funktionsweise der erfidnungsgemäßen Vorrichtung ist die Folgende:The functioning of the device according to the invention is as follows:

Die Wasserableitung 12 besitzt endseitig ein Magnetventil. Öffnet dieses Magnetventil, so kann durch die Ableitung 12 Wasser aus dem Behälter 1 herausströmen. Durch die Düse 11 und das sich öffnende Magnetventil 17 wird Wasser in den Behälter eingeleitet. Das eingeleitete Wasser ist im Wesentlichen CO2frei. Das aus der Leitung 12 heraustretende Wasser ist mit CO2 angereichert. Die Zuführung des CO2 erfolgt durch ein Rückschlagventil 16 von einer CO2-Flasche oder dergleichen. Dabei durchströmt das CO2 den Kanal 15, um durch die porösen Hohlkörper 2 in das Wasser auszutreten und sich darin teilweise zu lösen. Sich im Wasser nicht gelöstes CO2 sammelt sich in dem Kopfvolumen 10, um dort in der Pumpe 6 abgesaugt zu werden. Das abgesaugte CO2 wird über die Rückführungsleitung 25 wieder in den CO2-Kanal 15 zurückgeführt.The water drain 12 has a solenoid valve at the end. If this solenoid valve opens, water can flow out of the container 1 through the drain 12. Water is introduced into the container through the nozzle 11 and the opening solenoid valve 17. The water introduced is essentially CO 2 free. The water emerging from line 12 is enriched with CO 2 . The CO 2 is supplied by a check valve 16 from a CO 2 bottle or the like. The CO 2 flows through the channel 15 in order to exit through the porous hollow bodies 2 into the water and to partially dissolve therein. CO 2 which is not dissolved in the water collects in the head volume 10 in order to be sucked off there in the pump 6. The extracted CO 2 is returned to the CO 2 channel 15 via the return line 25.
