Description

Vorrichtung zum Herstellen von mit Kohlendioxid versetztem Tafelwasser Device for producing carbonated water
Die Erfindung betrifft eine Vorrichtung zum Herstellen von mit Kohlendioxid versetztem Tafelwasser nach dem Oberbegriff des Anspruchs 1.The invention relates to a device for producing carbonated water, according to the preamble of claim 1.
Als Alternative zu dem Kauf von fertigem Sprudel ist es bekannt, daß man den Sprudel auch zu Hause in entsprechenden Sprudelgeräten herstellen kann. Zu diesem Zweck wird aus dem Wasserhahn stammendes Wasser in dem Gerät mit Kohlendioxid versetzt. Auf diese Weise erhält man ohne großen technischen Aufwand Tafelwasser.As an alternative to buying finished sparkling water, it is known that the sparkling water can also be produced at home in corresponding sparkling water devices. For this purpose, water coming from the tap is mixed with carbon dioxide in the device. In this way, table water is obtained without great technical effort.
Die bisher bekannten Geräte zum Herstellen von mit Kohlendioxid versetztem Tafelwasser für den Hausgebrauch haben den Nachteil, daß die Mischeinrichtung zum Zuführen des Kohlendioxids in das Wasser deshalb sehr voluminös ist, weil ein Vorratsbehälter für das Wasser vorgesehen ist, über dem sich eine Kohlendioxidatmosphäre im Überdruck mit dem Ziel befindet, daß sich das Kohlendioxid allmählich in dem Wasser löst. Neben der großen Bauweise ist auch der Wirkungsgrad der Einbringung des Kohlendioxids in das Wasser nicht optimal.The previously known devices for producing carbon dioxide-added table water for domestic use have the disadvantage that the mixing device for supplying the carbon dioxide into the water is very voluminous because a storage container for the water is provided, over which a carbon dioxide atmosphere in excess pressure is provided the goal is that the carbon dioxide gradually dissolves in the water. In addition to the large construction, the efficiency of introducing the carbon dioxide into the water is also not optimal.
Davon ausgehend liegt der Erfindung die A u f g a b e zugrunde, eine Vorrichtung zum Herstellen von mit Kohlendioxid versetztem Tafelwasser mit einer verbesserten Mischeinrichtung zu schaffen.Proceeding from this, the invention is based on the objective of creating a device for producing carbonated water with an improved mixing device.
Die technische L ö s u n g ist gekennzeichnet durch die Merkmale im Kennzeichen des Anspruchs 1.The technical solution is characterized by the features in the characterizing part of claim 1.
Dadurch ist eine Vorrichtung zum Herstellen von mit Kohlendioxid versetztem Tafelwasser geschaffen, welche sich durch eine optimale Mischeinrichtung zum Zuführen des Kohlendioxids in das Wasser auszeichnet. Die Grundidee der Mischeinrichtung liegt in einer Mi- krostruktur, welche beispielsweise - und insbesondere - durch Kunststoff oder durch eine Keramik gebildet sein kann. Diese MikroStruktur besitzt eine große Anzahl von kleinen Austrittsöffnungen einerseits für das Wasser und andererseits für das Kohlendioxid. Da diese Austrittsöffnungen dicht nebeneinanderliegen und damit eine große Oberfläche und kurze Diffusionswege gebildet werden, kommt das ausströmende Kohlendioxid durch den engen Kontakt mit dem Wasser sofort in Lösung, so daß das Kohlendioxid im Mikromischer direkt in das Wasser eingebracht wird. Die Austrittsöffnungen weisen vorzugsweise einen Durchmesser unter 1 mm, besonders bevorzugt einen Durchmesser unter 200 μm auf. Ein Vorteil der erfindungsgemäßen Vorrichtung besteht darin, daß die Vielzahl der Austrittsöffnungen jeweils einen gleichen Durchmesser aufweisen. Hierdurch wird durch die Wahl des Durchmessers der Austrittsöffnungen eine Einstellbarkeit der Konzentration von Kohlendioxid im Tafelwasser erreicht. Diese MikroStruktur als Mischeinrichtung hat zum einen den Vorteil, daß sie klein baut und zum anderen den Vorteil, daß der Wirkungsgrad sehr hoch und die Verweilzeit Wasser/Kohlendioxid sehr kurz ist. Dadurch wird unmittelbar nach dem Mischen der beiden Komponenten das Tafelwasser ohne Beruhigungsphase sofort ausgeschenkt. Durch exakt definierte Abmessungen der MikroStrukturen der Mischeinrichtung werden dabei exakt einstellbare Konzentrationen von Kohlendioxid in Wasser erreicht. Da die durch die kleinen Austrittsöffnungen nebeneinander austretenden Fluide einen senkrecht zu ihrer Strömungsrichtung kleinen Querschnitt aufweisen, kann aufgrund der kurzen Diffusionswege eine schnelle Anreicherung des Kohlendioxids im Tafelwasser erfolgen. Ein weiterer Vorteil beim Einsatz von Mikromischem aus schlecht wärmeleitenden Stoffen, wie Kunststoff, ist die im Vergleich zu makroskopischen Mischern effektivere und schnellere Temperaturregelung durch die Kombination und/oder Integration der Mikromischer und Heiz- und/oder Kühlelementen.This creates a device for producing table water mixed with carbon dioxide, which is characterized by an optimal mixing device for feeding the carbon dioxide into the water. The basic idea of the mixing device lies in a microstructure, which can be formed, for example - and in particular - by plastic or by a ceramic. This micro structure has a large number of small outlet openings on the one hand for the water and on the other hand for the carbon dioxide. Since these outlet openings lie close together and thus a large surface area and short diffusion paths are formed, the outflowing carbon dioxide immediately comes into solution through the close contact with the water, so that the carbon dioxide is introduced directly into the water in the micromixer. The outlet openings preferably have a diameter of less than 1 mm, particularly preferably a diameter of less than 200 μm. An advantage of the device according to the invention is that the large number of outlet openings each have the same diameter. As a result, the concentration of carbon dioxide in the table water can be adjusted by the choice of the diameter of the outlet openings. This micro structure as a mixing device has the advantage on the one hand that it is small and on the other hand the advantage that the efficiency is very high and the residence time water / carbon dioxide is very short. As a result, the table water is poured out immediately after the two components have been mixed without a calming phase. Precisely adjustable concentrations of carbon dioxide in water are achieved through precisely defined dimensions of the microstructures of the mixing device. Since the fluids emerging through the small outlet openings next to one another have a small cross section perpendicular to their direction of flow, the short diffusion paths allow rapid enrichment of the carbon dioxide in the table water. Another advantage of using micromixers made from poorly heat-conducting materials, such as plastic, is that the temperature control is more effective and faster than that of macroscopic mixers, by combining and / or integrating the micromixers and heating and / or cooling elements.
Die Weiterbildung gemäß Anspruch 2 hat den Vorteil, daß ein größtmöglicher Kontakt zwischen den beiden Medien Wasser und Kohlendioxid geschaffen ist. Grundsätzlich ist es dabei auch denkbar, daß die Austrittsöffnungen matrixartig ausgebildet sind, wobei zwischen den Matrixpunkten der Wasseraustrittsöffnungen die Matrixpunkte der Kohlendioxidaustrittsöffnungen liegen.The development according to claim 2 has the advantage that the greatest possible contact between the two media water and carbon dioxide is created. Basically, it is also conceivable that the outlet openings are formed in a matrix-like manner, the matrix points of the carbon dioxide outlet openings lying between the matrix points of the water outlet openings.
Die Weiterbildung gemäß Anspruch 3 schlägt Ausbildungen der Austrittsöffnungen in Form von Düsen vor, wobei die Querschnittsform im wesentlichen punktförmig ausgebildet ist.The development according to claim 3 proposes designs of the outlet openings in the form of nozzles, the cross-sectional shape being essentially point-shaped.
Demgegenüber schlägt die Weiterbildung gemäß Anspruch 4 eine Alternative in der Form der Düsen als Schlitze vor, welche parallel nebeneinanderliegen. Die Wirkungsweise hier ist derart, daß das Wasser sowie das Kohlendioxid durch den jeweiligen Schlitz in der Art eines Vorhanges oder Schleiers ausströmt, so daß sich die abwechselnden "Wände" von Wasser und Kohlendioxid miteinander vermischen.In contrast, the further development according to claim 4 proposes an alternative in the form of the nozzles as slots which are parallel to one another. The mode of operation here is such that the water and the carbon dioxide flow out through the respective slit in the manner of a curtain or veil, so that the alternating "walls" of water and carbon dioxide mix with one another.
Eine bevorzugte Ausbildung der Mikrostruktur schlägt die Weiterbildung gemäß Anspruch 5 vor. Die Grundidee liegt in einem lamellenartigen Mikromischersystem, wobei die kammartigen Strukturen Führungskanäle für das Wasser sowie für das Kohlendioxid bilden. Mittels dieser MikroStrukturen ist es auf technisch einfache Weise möglich, die beiden miteinander zu vermischenden Medien, nämlich das Wasser sowie das Kohlendioxid in Kontakt miteinander zu bringen. Insbesondere lassen sich diese kammartigen Strukturen auf plattenförmi- gen Elementen ausbilden, wobei eine ebene Gegenplatte auf den lamellenartigen, kammartigen Strukturen die Fließkanäle begrenzt.A further development according to claim 5 proposes a preferred embodiment of the microstructure. The basic idea lies in a lamella-like micromixer system, the comb-like structures forming guide channels for the water and for the carbon dioxide. Using these microstructures, it is possible in a technically simple manner to bring the two media to be mixed together, namely the water and the carbon dioxide, into contact with one another. In particular, these comb-like structures can be form elements, with a flat counterplate on the lamellar, comb-like structures delimiting the flow channels.
Gemäß der Weiterbildung in Anspruch 6 ist der Wasserzuführung eine Desinfektion vorgeschaltet, um die MikroStruktur sowie die Ausschankmechanik keimfrei zu machen.According to the development in claim 6, the water supply is preceded by disinfection in order to make the microstructure and the dispensing mechanism sterile.
Eine Alternative hierzu (oder auch zusätzlich) schlägt die Weiterbildung gemäß Anspruch 7 vor, wobei das Heizen des Wassers auf beispielsweise 95°C ebenfalls Bakterien abtötet.An alternative to this (or also in addition) is proposed by the development according to claim 7, wherein heating the water to, for example, 95 ° C. also kills bacteria.
Damit das Tafelwasser gekühlt ist, schlägt die Weiterbildung gemäß Anspruch 8 vor, daß der Mischeinrichtung eine Kühlung vorgeschaltet ist.So that the table water is cooled, the development according to claim 8 proposes that the mixing device is preceded by cooling.
Die Grundidee der Weiterbildung gemäß Anspruch 9 besteht darin, daß die Kühleinrichtung direkt der Mischeinrichtung dergestalt zugeordnet ist, daß gleichzeitig während der Zuführung des Kohlendioxids in das Wasser dieses (sowie das Kohlendioxid) und damit das Tafelwasser gekühlt wird. Der Vorteil besteht darin, daß durch die Integration der Kühleinrichtung in die Mischeinrichtung Elemente der Mischeinrichtung zugleich auch für die Kühleinrichtung verwendet werden können. Insgesamt ist damit die Kühlung des Tafelwassers verbessert. Ein weiterer Vorteil besteht darin, daß im Falle, daß die erfindungsgemäße Vorrichtung zumindest teilweise oder ganz aus Kunststoff besteht, das Tafelwasser ohne zusätzliche Kühlphasen abgegeben werden kann, da die Mischeinrichtung eine kleine Masse aufweist und dies eine entsprechend schnelle Temperaturänderung bzw. -regelung ermöglicht.The basic idea of the development according to claim 9 is that the cooling device is directly assigned to the mixing device in such a way that at the same time as the carbon dioxide is being fed into the water (and the carbon dioxide) and thus the table water is cooled. The advantage is that by integrating the cooling device into the mixing device, elements of the mixing device can also be used for the cooling device. Overall, the cooling of the table water is improved. Another advantage is that in the event that the device according to the invention consists at least partially or entirely of plastic, the table water can be dispensed without additional cooling phases, since the mixing device has a small mass and this enables a correspondingly rapid temperature change or regulation.
Eine bevorzugte Ausbildung der Kühleinrichtung in Form eines Peltier-Elements schlägt die Weiterbildung gemäß Anspruch 10 vor. Dabei dient die Kalt-Seite des Peltier-Elements dem Kühlen. Das Peltier-Element kann dabei vorzugsweise plattenförmig ausgebildet sein. Die Verwendung eines Peltier-Elements als Kühleinrichtung stellt eine einfache Möglichkeit zur technischen Realisierung der Kühleinrichtung dar.A preferred embodiment of the cooling device in the form of a Peltier element is proposed by the development according to claim 10. The cold side of the Peltier element is used for cooling. The Peltier element can preferably be plate-shaped. The use of a Peltier element as a cooling device represents a simple possibility for the technical implementation of the cooling device.
Eine Weiterbildung hiervon schlägt Anspruch 11 vor, daß nämlich durch eine Spannungsumkehr des Peltier-Elements die Kalt-Seite zur Warm-Seite wird und damit das durchfließende Wasser auf beispielsweise 95°C erhitzt wird. Dadurch kann das Peltier-Element bedarfsweise zur Desinfektion der Mischeinrichtung sowie der nachgeschalteten Ausschankmechanik verwendet werden.A further development of this suggests claim 11, namely that by reversing the voltage of the Peltier element, the cold side becomes the warm side and thus the water flowing through is heated to, for example, 95 ° C. As a result, the Peltier element can be used, if necessary, for disinfecting the mixing device and the downstream dispensing mechanism.
Eine Alternative hierzu schlägt die Weiterbildung gemäß Anspruch 12 mit der Verwendung einer Heizeinrichtung zur Desinfektion vor. Eine bevorzugte Weiterbildung schlägt Anspruch 13 vor, wobei der Grundgedanke darin besteht, die Kühleinrichtung insbesondere in Form des Peltier-Elements mit der Mikrostruk- tur zur Zuführung des Kohlendioxids in das Wasser zu kombinieren. Dabei ist sowohl die Mikrostruktur für die Kohlendioxidzuführung einerseits sowie die Peltier-Kühlung andererseits in einem gemeinsamen System dergestalt integriert, daß die Mikrostruktur im Wirkzusammenhang mit dem Peltier-Element steht.The further development according to claim 12 proposes an alternative to this with the use of a heating device for disinfection. A preferred further development proposes claim 13, the basic idea being to combine the cooling device, in particular in the form of the Peltier element, with the microstructure for feeding the carbon dioxide into the water. Both the microstructure for the carbon dioxide supply on the one hand and the Peltier cooling on the other hand are integrated in a common system in such a way that the microstructure is in operative connection with the Peltier element.
Die Weiterbildung hiervon gemäß Anspruch 14 schlägt vor, für die Mikrostruktur ein - von der Kühleinrichtung - separates Plattenelement vorzusehen. Das Peltier-Element ist dann direkt an der Mikrostruktur angeordnet und bildet dessen räumliche Begrenzung.The further development thereof according to claim 14 proposes to provide a separate plate element for the microstructure - from the cooling device. The Peltier element is then arranged directly on the microstructure and forms its spatial limitation.
Eine Alternative hierzu schlägt Anspruch 15 vor, bei der das Peltier-Element mit einer integrierten, d.h. aufgetragenen Mikrostruktur versehen ist.An alternative to this is proposed in claim 15, in which the Peltier element with an integrated, i.e. applied microstructure is provided.
Die Weiterbildung gemäß Anspruch 16 geht von dem Grundgedanken aus, daß die Mikrostruktur nicht nur zur Zuführung des Kohlendioxids in das Wasser dient, sondern daß diese Mikrostruktur auch zum Abtransport der Wärme mittels eines kontinuierlich durchfließenden Wasserstroms dienen kann, wobei die Abführung der Wärme über mikromechanische Strukturen erfolgt.The development according to claim 16 is based on the basic idea that the microstructure not only serves to supply the carbon dioxide into the water, but that this microstructure can also serve to remove the heat by means of a continuously flowing water stream, the heat being dissipated via micromechanical structures he follows.
Die Grundidee der Weiterbildung gemäß Anspruch 17 besteht darin, vom Grundprinzip und von der Anordnung her herkömmliche Wasserarmaturen zu verwenden, welche jedoch zusätzlich mit einer Mischeinrichtung zum Zuführen des Kohlendioxids in das Wasser bestückt sind. Dadurch ist eine direkte Erzeugung von Tafelwasser im Mikromischverfahren möglich. Der besondere Vorteil der Mischeinrichtung innerhalb der Wasserarmatur besteht darin, daß das mit dem Kohlendioxid versetzte Wasser gleich abgegeben wird und somit kein mit Kohlendioxid versetztes Wasser in der Leitung "steht". Die Mischeinrichtung kann als eine Art Patrone im Zapfhahn integriert sein. Durch eine entsprechende Ausbildung der Mischeinrichtung besitzt diese nur eine kleine Dimension, so daß sich die so modifizierte Wasserarmatur von herkömmlichen Wasserarmaturen von der Größe her nicht unterscheidet. Bei der Mischeinrichtung kann es sich um einen Mikromischer mit integrierter zylindrischer Form handeln. Die Umschaltung sowie Zuschaltung von Kohlendioxid zu dem Wasser kann durch einfache Bedienelemente technisch realisiert werden.The basic idea of the development according to claim 17 is to use conventional water fittings from the basic principle and from the arrangement, but which are additionally equipped with a mixing device for supplying the carbon dioxide into the water. This enables a direct production of table water using the micromixing process. The particular advantage of the mixing device within the water fitting is that the water mixed with the carbon dioxide is emitted immediately and thus no water mixed with carbon dioxide "stands" in the line. The mixing device can be integrated as a type of cartridge in the tap. By appropriately designing the mixing device, it has only a small dimension, so that the water fitting modified in this way does not differ in size from conventional water fittings. The mixing device can be a micromixer with an integrated cylindrical shape. The switchover and connection of carbon dioxide to the water can be implemented technically using simple controls.
Die Weiterbildung gemäß Anspruch 18 hat den Vorteil, daß bei abgeschalteter oder gedrosselter Kohlendioxid-Zufuhr "Stilles Wasser" bzw. "Medium" gezapft werden kann. Gemäß der Weiterbildung in Anspruch 19 ist auch die Variante möglich, bei welcher Wasser an der Mischeinrichtung vorbeigeleitet wird. Dies entspricht der Funktion eines "üblichen" Wasserhahns.The development according to claim 18 has the advantage that "still water" or "medium" can be tapped when the carbon dioxide supply is switched off or throttled. According to the development in claim 19, the variant is also possible in which water is directed past the mixing device. This corresponds to the function of a "normal" faucet.
Eine weitere Weiterbildung mit der zusätzlichen Zuführung von Sirup schlägt Anspruch 20 vor. Die Grundidee liegt in der Herstellung von Mischgetränken, d.h. dem reinen Tafelwasser wird ein Sirupkonzentrat in der Armatur oder unmittelbar nach der Armatur zugeführt, damit das Getränk eine bestimmte Geschmacksrichtung erhält. Dabei können zusätzliche Leitungen in der Wasserarmatur für die Sirupbeimischung integriert werden. Die Zuschaltung von Sirup oder ähnlichen Zusätzen kann durch einfache Bedienelemente technisch realisiert werden. Somit wird zusammenfassend durch eine kombinierte Sirupzuführung die Beimengung verschiedener Geschmacksstoffe ermöglicht.A further development with the additional supply of syrup proposes claim 20. The basic idea lies in the production of mixed drinks, i.e. A syrup concentrate is added to the pure table water in the tap or immediately after the tap, so that the drink gets a certain flavor. Additional lines can be integrated in the water fitting for the syrup admixture. The connection of syrup or similar additives can be technically implemented using simple controls. In summary, a mixed syrup feed enables the addition of different flavors.
Die Weiterbildung gemäß Anspruch 21 hat den Vorteil, daß der Kompensator direkt an der Öffnung des Zapfhahns ein vorzeitiges Entkarbonisieren des Tafelwassers verhindert und beim Zapfen des Tafelwassers den Überdruck in dem Sinne schonend abbaut, daß das Kohlendioxid nicht übermäßig entweicht.The development according to claim 21 has the advantage that the compensator directly at the opening of the tap prevents premature decarbonization of the table water and gently reduces the overpressure when the table water is tapped in the sense that the carbon dioxide does not escape excessively.
Schließlich schlägt die Weiterbildung gemäß Anspruch 22 eine Peltier-Kühlung vor. Diese kann in der Wasserarmatur integriert oder an dieser adaptiert sein. Dadurch ist eine technisch einfache Möglichkeit zum Kühlen des Tafelwassers geschaffen.Finally, the development according to claim 22 proposes Peltier cooling. This can be integrated in the water fitting or adapted to it. This creates a technically simple way of cooling the table water.
Die Merkmale in den Unteransprüchen 2 bis 22 stellen - unabhängig vom Gegenstand des Hauptanspruches - jeweils eigenständige Erfindungen dar.The features in subclaims 2 to 22 each represent independent inventions, regardless of the subject matter of the main claim.

Die Vorrichtung zum Herstellen von mit Kohlendioxid versetztem Tafelwasser der rein schematischen Darstellungen in Fig. 1 und 2 weist eine Mischeinrichtung 1 mit einer Wasserzuführung 2 sowie einer Kohlendioxidzuführung 3 auf. In die Wasserzuführung 2 ist eine Heizeinrichtung/Desinfektionseinrichtung 4 geschaltet.The device for producing table water mixed with carbon dioxide of the purely schematic representations in FIGS. 1 and 2 has a mixing device 1 with a water supply 2 and a carbon dioxide supply 3. A heating device / disinfection device 4 is connected into the water supply 2.
Die Mischeinrichtung 1 besitzt eine Kühleinrichtung 5 in Form eines Peltier-Elements. Dieses ist an eine Spannungsversorgungseinrichtung 6 angeschlossen (welches gleichzeitig auch die Heizeinrichtung 4 steuert). Das Peltier-Element der Kühleinrichtung 5 ist sandwichartig zwischen zwei Plattenelementen 7 angeordnet, wobei in Fig. 2 das linke Plattenelement 7 an die Wasserzuführung 2 sowie an die Kohlendioxidzuführung 3 angeschlossen ist, während das rechte Plattenelemlent 7 an Kühlleitungen 8 angeschlossen ist.The mixing device 1 has a cooling device 5 in the form of a Peltier element. This is connected to a voltage supply device 6 (which also controls the heating device 4 at the same time). The Peltier element of the cooling device 5 is sandwiched between two plate elements 7, the left plate element 7 in FIG. 2 being connected to the water supply 2 and to the carbon dioxide supply 3, while the right plate element 7 is connected to cooling lines 8.
Der Mischeinrichtung 1 ist eine Mikrostruktur 9 zugeordnet. Bei der Ausführungsform der Fig. 3 sowie 5 und 6 ist diese Mikrostruktur 9 auf beiden Seiten des Peltier-Elements der Kühleinrichtung 5 angeordnet, während bei der Ausführungsform der Fig. 4 sowie der Fig. 7 und 8 die Mikrostruktur 9 auf den Plattenelementen 7 angeordnet ist.A microstructure 9 is assigned to the mixing device 1. In the embodiment of FIGS. 3 and 5 and 6, this microstructure 9 is arranged on both sides of the Peltier element of the cooling device 5, while in the embodiment of FIGS. 4 and 7 and 8 the microstructure 9 is arranged on the plate elements 7 is.
Bei der Darstellung in Fig. 1 ist die Mikrostruktur 9 der Mischeinrichtung 1 nicht erkennbar. Sie ist auf der abgewandten Unterseite der Darstellung angeordnet. Erkennbar in Fig. 1, d.h. auf der sichtbaren Oberseite der Darstellung ist jedoch eine weitere Mikrostruktur, welche in Fig. 2 zwischen dem Peltier-Element und dem rechten Plattenelement 7 angeordnet ist. Diese Mikrostruktur ist somit an die Kühlleitungen 8 angeschlossen und dient aufgrund ihrer großen Oberfläche der verbesserten Kühlung der Warm-Seite des Peltier-Elements der Kühleinrichtung 5.1, the microstructure 9 of the mixing device 1 cannot be seen. It is arranged on the opposite bottom of the illustration. Can be seen in Fig. 1, i.e. on the visible upper side of the illustration, however, is another microstructure which is arranged in FIG. 2 between the Peltier element and the right plate element 7. This microstructure is thus connected to the cooling lines 8 and, due to its large surface area, serves to improve the cooling of the warm side of the Peltier element of the cooling device 5.
Die MikroStrukturen 9 sind mit zwei Kammstrukturen ausgebildet, wobei die Finger 10 der beiden Kammstrukturen entgegengesetzt gerichtet ineinandergreifen. Die eine Kammstruktur ist dabei an die Wasserzuführung 2 und die andere Kammstruktur an die Kohlendioxidzuführung 3 angeschlossen. In der Mitte der Strukturen besitzt dabei das Plattenelement 7 eine schlitzartige Durchtrittsöffnung 11. Da die Plattenelemente 7 an dem Peltier-Element der Kühleinrichtung 5 eben anliegen, bilden die entsprechenden Durchtrittsöffnungen 11 im Zusammenwirken mit den kammartigen Kanalstrukturen Austrittsöffnungen 12 mit einem im wesentlichen rechteckigen Querschnittsprofil. Dabei wechseln sich Austrittsöffnungen 12 einerseits für das Wasser und andererseits für das Kohlendioxid miteinander ab.The microstructures 9 are formed with two comb structures, the fingers 10 of the two comb structures interlocking in opposite directions. One comb structure is connected to the water supply 2 and the other comb structure to the carbon dioxide supply 3. In the middle of the structures, the plate element 7 has a slot-like passage opening 11. Since the plate elements 7 on the Peltier element of the cooling device 5, the corresponding through openings 11, in cooperation with the comb-like channel structures, form outlet openings 12 with an essentially rectangular cross-sectional profile. Outlet openings 12 alternate with one another for the water and on the other hand for the carbon dioxide.
Die Funktionsweise der Mischeinrichtung 1 ist wie folgt:The functioning of the mixing device 1 is as follows:
Das Wasser wird mittels einer Pumpe 13 der Mischeinrichtung 1 zugeführt. Ebenso wird aus einem Vorratsbehälter 14 Kohlendioxid der Mischeinrichtung 1 zugeführt. Durch die kammartige Mikrostruktur 9 wird das Wasser sowie das Kohlendioxid in den kammartigen Kanälen geführt, bis diese Medien durch die Austrittsöffnungen 12 austreten. Nach diesem Austritt kommt das Wasser mit dem Kohlendioxid in Kontakt, so daß sie sich miteinander dergestalt vermischen, daß sich das Kohlendioxid in dem Wasser löst. Der Austrag des so hergestellten Tafelwassers erfolgt über die Leitung 15. Da sich die Durchmischungsstrukturen im Bereich der Kalt-Seite des Peltier-Elements der Kühleinrichtung 5 befinden, wird gleichzeitig das Tafelwasser gekühlt. Die Kühlung des Peltier-Elements erfolgt auf der Warm-Seite mittels der Kühlleitungen 8.The water is fed to the mixing device 1 by means of a pump 13. Likewise, carbon dioxide is fed to the mixing device 1 from a storage container 14. Through the comb-like microstructure 9, the water and the carbon dioxide are guided in the comb-like channels until these media exit through the outlet openings 12. After this exit, the water comes into contact with the carbon dioxide so that they mix with one another in such a way that the carbon dioxide dissolves in the water. The bottled water thus produced is discharged via line 15. Since the mixing structures are located in the region of the cold side of the Peltier element of the cooling device 5, the bottled water is cooled at the same time. The Peltier element is cooled on the warm side by means of the cooling lines 8.
Die Fig. 9 zeigt eine beispielhafte Anwendung der Mischeinrichtung 1 mit der Mikrostruktur 9 in einer Wasserarmatur 16, wie sie üblicherweise an einem Wasserbecken 17 vorhanden ist. Das Besondere an dieser Wasserarmatur 16 ist, daß die Mikrostruktur 9 der Mischeinrichtung 1 in der Wasserarmatur 16 integriert ist und somit während des Zapfens des Wassers durch diese Mischeinrichtung 1 Kohlendioxid zugeführt wird. In dem Zapfhahn 18 der Wasserarmatur 16 befindet sich noch ein Kompensator 19, welcher ein vorzeitiges Entkarbonisieren des Tafelwassers verhindert und beim Zapfen des Tafelwassers den Überdruck abbaut.FIG. 9 shows an exemplary application of the mixing device 1 with the microstructure 9 in a water fitting 16, as is usually present in a water basin 17. What is special about this water fitting 16 is that the microstructure 9 of the mixing device 1 is integrated in the water fitting 16 and thus carbon dioxide is supplied through this mixing device 1 while the water is being drawn off. In the tap 18 of the water fitting 16 there is also a compensator 19 which prevents premature decarbonization of the table water and reduces the excess pressure when the table water is drawn.
Schließlich ist der Wasserarmatur 16 noch eine Sirupzuführung 20 zugeordnet, mittels der wahlweise dem Tafelwasser Sirup beigemengt werden kann. Finally, the water fitting 16 is also assigned a syrup feed 20, by means of which syrup can optionally be added to the table water.
