Diesem Vorratsbehälter, dem sogenannten Karbonisa¬ tor, wird normales Wasser in Trinkqualität entweder aus der Leitung eines Wasserversorgungssystems oder einem Vorratsbe¬ hälter unter ausreichendem Druck zugeführt, wobei das zuge¬ führte Wasser selbst unter Druck stehen kann oder aber durch eine Druckpumpe ausschließlich oder zusätzlich in den Karbo¬ nisator gefördert wird. Außerdem wird dem Karbonisator2 Precondition for a prepared cool soft drink chilled. Normal water in drinking quality is fed to this storage container, the so-called carbonator, either from the line of a water supply system or from a storage container under sufficient pressure, the supplied water itself being able to be under pressure or else exclusively or additionally by a pressure pump the carbonator is promoted. It also becomes the carbonizer

Durch verschiedene Maßnahmen wird die Karbonisierung des Wassers im Karbonisator mit dem zugeführten CO -Gas durchgeführt bzw. unterstützt, wobei sich der Einsatz von im Karbonisator angeordneten Umwälzpumpen bewährt hat. Diese saugen aus dem mit CO -Gas gefüllten Kopfbereich des Karbonisators dieses CO -Gas an und führen dieses in das in Bewegung, insbesonde¬ re in Drehung versetzte Wasser ein. Wie bereits ausgeführt, dient eine Kühlung des Karbonisators zum einen der Verbesse¬ rung der Karbonisierung und zum anderen als Voraussetzung, daß das endgültig bereitete und ausgegebene Getränk die ge¬ wünschte niedrige und im wesentlichen konstante Temperatur aufweist. Die Kühlung des Karbonisators erfolgt zweckmäßig über ein Kühlsystem, das in der Lage ist, im Seitenbereich der Seitenwandungen des Karbonisators einen Eismantel aufzu¬ bauen, welcher sich durch das umgewälzte Wasser einigermaßen gleich stark ausbildet. Dadurch wird "Kältekapazität" ge¬ speichert und das Kühlsystem braucht nicht extrem leistungs¬ stark ausgelegt werden, wie dies bei Durchflußkühlung not-2 2 ter via a pressure reducing valve, so that a pressure of approx. 4 bar is built up in the carbonator. The carbonation of the water in the carbonator is carried out or supported with the supplied CO gas by various measures, the use of circulation pumps arranged in the carbonator having proven successful. These suck this CO gas from the head region of the carbonator filled with CO gas and introduce it into the water which is set in motion, in particular in rotation. As already stated, cooling the carbonator serves on the one hand to improve the carbonation and on the other hand as a prerequisite that the final prepared and dispensed beverage has the desired low and essentially constant temperature. The carbonator is expediently cooled by means of a cooling system which is able to build up an ice jacket in the side region of the side walls of the carbonator, which ice jacket is formed to a certain extent by the circulated water. As a result, "cooling capacity" is stored and the cooling system need not be designed to be extremely powerful, as is necessary in the case of flow cooling.

Wird beispielsweise im beschriebenen Anwendungsfall die Aus¬ gabe eines frisch bereiteten Erfrischungsgetränks gewünscht, so wird in einer an den Bodenbereich des Karbonisators an¬ schließenden Leitung ein Absperrventil geöffnet und das ge¬ kühlte, karbonisierte Wasser zu diesem Zweck entnommen. Da das Wasser von im Hinblick auf den sich ausbildenden Eisman¬ tel im Bereich der Kühlschlangen in die Nähe des Gefrier¬ punktes gekühlt ist, besteht eine gewisse Gefahr, daß Eis¬ teilchen oder -teile in den Bereich der Ausflußöffnung ge¬ langen und diese verstopfen.If, for example, in the described application, the delivery of a freshly prepared soft drink is desired, a shut-off valve is opened in a line connected to the bottom area of the carbonator and the cooled, carbonated water is removed for this purpose. Since the water is cooled in the area of the cooling coils in the vicinity of the freezing point with regard to the ice coat being formed, there is a certain risk that ice particles or parts will get into the area of the outflow opening and block it .
Die Eisbildung innerhalb des Vorratsbehälters soll in Berei¬ chen erfolgen, die für die sonstige Betriebsweise des Vor¬ ratsbehälters als Karbonisator unproblematisch sind. Diese Bereiche sind die seitlichen Wandungen des Vorratsbehälters, welche von den Kühlschlangen des Kühlsyste s thermisch gut leitend umgeben sind. In diesem Bereich wird sich auch tat¬ sächlich die Eisbildung entwickeln und ein bereits vorhande¬ ner Eismantels wird bei weiterer Kühlung sich auch dort ver¬ größern. Probleme bei der Betriebsweise von derartigen kar¬ bonisierenden Vorratsbehältern haben zu Beobachtungen ge¬ führt, die ergaben, daß zumindest bei karbonisiertem Wasser sich dieses bei üblich angewandten, stetigen Wärmeentzug sich unter die typische Gefriertemperatur abkühlen läßt, oh¬ ne daß eine Eisbildung einsetzt. Durch Wärmefluß und Konvek- tion kann sich dann im Vorratsbehälter im wesentlichen über den gesamten Bereich ein Temperaturwert einstellen, der un¬ ter dem eigentlichen Gefrierpunkt liegt, mit der Folge, daß nunmehr der Gefriervorgang in unkontrollierter Weise an be-Ice formation within the storage container should take place in areas which are unproblematic for the other operating mode of the storage container as a carbonizer.

2 Erzeugung von karbonisiertem Wasser in einem gekühlten Vor¬ ratsbehälter, die dieser Aufgabe gerecht wird, ist erfin¬ dungsgemäß dadurch gekennzeichnet, daß im Bereich der durch die Kühlleitungen des Kühlkreislaufs beaufschlagten Wandung des Vorratsbehälters Maßnahmen zur gezielten örtlichen, ge¬ genüber den übrigen Bereichen vorgezogenen Eisbildung ge¬ troffen sind.2 Production of carbonated water in a cooled storage tank, which does this task, is inventively characterized in that in the area of the wall of the storage tank acted upon by the cooling lines of the cooling circuit, measures for targeted local, preferred over the other areas are preferred Ice formation are affected.
Als Maßnahme zur bevorzugten lokalen Eisbildung im Vorrats¬ behälter im Nahbereich, in dessen Kühlleitung ist nach einer bevorzugten Ausgestaltung der erfindungsgemmäßen Vorrichtung ein Raum für den Vorratsbehälterinhalt abgetrennt, welcher strömungsarm oder strömungslos zum Vorratsbehälterinneren offen ist. Bevorzugt ist dieser abgetrennte Raum kleiner als 100 mmjijj und es ist zweckmäßig in kleiner als 10 mmjiji auszu¬ bilden.As a measure for the preferred local ice formation in the storage container in the vicinity, in its cooling line, according to a preferred embodiment of the device according to the invention, a space for the storage container content is separated, which is open to the interior of the storage container with little or no flow. This separated space is preferably less than 100 mmjijj and it is expedient to design it in less than 10 mmjiji.
Diese bevorzugte Ausgestaltung in Form eines vom Vorratsbe¬ hälterinneren strömungstechnisch abgetrennten Raum ist bei¬ spielsweise durch ein auf die Vorratsbehälterwandung im Be¬ reich der Kühlleitung aufgesetztes Rohr realisierbar. EineThis preferred embodiment in the form of a fluidically separated space from the inside of the storage container can be realized, for example, by means of a pipe placed on the storage container wall in the area of the cooling line. A
ERSATZBLATT äußerst zweckmäßige Realisierung ist auch derart gegeben, daß der strömungstechnisch beruhigte Raum gebildet ist durch eine nach außen zwischen zwei Kühlleitungswendel gerichtete Ausprägung der Wandung des Vorratsbehälters und eine diese Ausprägung weitestgehend gegenüber dem Vorratsbehälterinne¬ ren abdeckenden Platine. Eine weitere bevorzugte Maßnahme zur partiellen, vorgezogenen Eisbildung läßt sich dadurch realisieren, daß die Wandung des Vorratsbehälters zumindest partiell im bevorzugt durch die Kühlleitung beaufschlagten oberen Bereich gegenüber dem Vorratsbehälterinneren aufge¬ rauht und ansonsten im unteren Bereich des Vorratsbehälters glatt ausgestaltet ist.REPLACEMENT LEAF Extremely expedient realization is also given in such a way that the fluidically calmed space is formed by an outward-directed configuration of the wall of the storage container between two cooling line coils and a circuit board covering this configuration as far as possible with respect to the storage container interior. A further preferred measure for the partial, advanced ice formation can be implemented in that the wall of the storage container is roughened at least partially in the upper region, which is preferably acted upon by the cooling line, in relation to the interior of the storage container and is otherwise smooth in the lower region of the storage container.
Die erfindungsgemäßen Maßnahmen führen dazu, daß partiell in einem begrenzten Bereich Kristallisationspunkte für die Eis¬ bildung geschaffen werden, von denen aus die Bildung des ge¬ wünschten Eismantels bei entsprechend kühlem Wasser sich wunschgemäß ausbildet. Partielle Unterkühlungen der Wandung sind ansonsten schwer zu realisieren, da durch die Wärmelei¬ tung in der Wandung und durch die Wärmeleitung und insbeson¬ dere die Konvektion in der Flüssigkeit derartige Unterschie¬ de kaum relevant wirksam gemacht werden können, es sei denn mit erheblichem Aufwand. Das Abtrennen einer kleinen Flüs¬ sigkeitsmenge von der Gesamtflüssigkeit jedoch bewirkt in diesem relativ kleinen und strömungstechnisch abgeschotteten Raum eine gezielte vorgezogene Eisbildung, die sich durch kleine, offene Stellen von diesem abgetrennten Raum in den Vorratsbehälter fortpflanzt. Die gemäß den bevorzugten Aus¬ gestaltungen abgetrennten kleinen Räume sind in diesem Zu¬ sammenhang besonders hilfreich und wirksam, jedoch hat sich auch gezeigt, daß partielle Aufrauhungen der Vorratsbehäl¬ terwandungen im Bereich der Kühlleitungen gegenüber anson-The measures according to the invention mean that crystallization points for ice formation are partially created in a limited area, from which the formation of the desired ice jacket with appropriately cool water forms as desired.

Der Eismantel 10 be¬ wirkt eine sehr konstante Wassertemperatur in der Nähe des Gefrierpunkts und bietet Kältepotential bei Ausgabe von kal¬ tem Wasser aus dem Vorratsbehälter und Nachfüllen von dem gegenüber wärmerem Wasser in den Vorratsbehälter.HE SA TZB The water supply is cooled via evaporator coils 9 of a cooling system, not shown, in such a way that an ice jacket 10 is located in the interior of the storage container 1 in the area of the evaporator coils 9, which are thermally conductive against the wall of the storage container builds up. The thickness of this ice jacket 10 is monitored by an ice sensor 11, from which the cooling circuit and thus the cooling capacity is controlled. The ice jacket 10 causes a very constant water temperature in the vicinity of the freezing point and offers cold potential when cold water is dispensed from the storage container and refilled with warmer water into the storage container.
Um die ursprüngliche Bildung des Eismantels 10 gezielt ein¬ zuleiten, ist im Bereich der untersten Windung der an der Wandung des Vorratsbehälters 1 thermisch gut leitend anlie¬ genden Verdampferleitung 9 ein Raum zum Inneren des Vorrats¬ behälters zwar offen, aber strömungstechnisch in das dort befindliche Wasser beruhigend angeordnet.In order to initiate the original formation of the ice jacket 10 in a targeted manner, a space to the inside of the storage container is open in the area of the lowest turn of the evaporator line 9, which has good thermal conductivity against the wall of the storage container 1, but is fluidically into the one located there Water arranged soothing.
Figur 2a zeigt diesen Raum etwas vergrößert als Innenbereich eines kleinen Rohres 13, welches senkrecht auf die Wandung des Vorratsbehälters 1 gegenüber einer Windung der Verdamp¬ ferleitung 9 aufgesetzt ist. Es zeigt sich, daß sich in die¬ sem Raum 12 bei Abkühlung des Wassers zum und unter den Ge¬ frierpunkt dort bevorzugt Eis bildet und bei in diesem Fall unterkühltem Wasser sich von dieser Kristallisationsstelle der Eismantel relativ rasch und schlagartig an der Wandung, die von der restlichen Verdampferleitung 9 umgeben ist, aus¬ breitet. Die sonstigen Bereiche innerhalb des Vorratsbehäl¬ ters 1 bleiben demgegenüber eisfrei. Oberhalb dieser Kri- stallisationsstelle durch den Raum 12 ist aufgrund des Dich-FIG. 2a shows this space somewhat enlarged as the inner area of a small tube 13, which is placed perpendicular to the wall of the storage container 1 opposite a turn of the evaporator line 9. It can be seen that when the water cools to and below the freezing point, ice preferably forms in this space 12, and in this case, undercooled water, the ice coat from this point of crystallization forms relatively quickly and abruptly on the wall, which is from the remaining evaporator line 9 is surrounded. In contrast, the other areas within the storage container 1 remain ice-free. Above this crystallization point through the room 12 is due to the
ERSATZBLATT teverhaltens von Wasser eher eine stärkere Unterkühlung an¬ zutreffen, so daß sich die Eisbildung nach oben zügig ent¬ wickelt.REPLACEMENT LEAF In relation to water, there is more of a hypothermia, so that the ice formation develops rapidly upwards.
Die Figur 2b zeigt einen noch stärker gegenüber dem Inneren des Vorratsbehälters 1 abgeschlossenen Raums 12', der ledig¬ lich über den ihn umgebenden Käfig mit dem Vorratsbehälter¬ inneren über zwei kleine Bohrungen 13 in Verbindung steht. Dadurch wird dieser Raum gesichert mit Wasser gefüllt und die Eiskristalle können sich im wesentlichen ungehindert nach außen entwickeln.FIG. 2b shows a space 12 'which is even more closed to the interior of the storage container 1 and which is only connected to the storage container interior via two small bores 13 via the cage surrounding it. This ensures that this space is filled with water and the ice crystals can develop to the outside essentially unhindered.
Die Figur 2c zeigt insoweit eine Modifikation der Ausbildung eines abgetrennten, der Eiskrstallisationsbildung dienenen Raumes 12" als dieser Raum durch eine Einbuchtung in der Wandung des Vorratsbehälters 1 zwischen zwei Windungen der Verdampferleitung realisiert ist, die durch ein Abdeckplätt- chen 17 mit zwei kleinen Durchbrüchen 18 abgedeckt ist.FIG. 2 c shows a modification of the design of a separate space 12 "which serves to form the ice installation as this space is realized by an indentation in the wall of the storage container 1 between two turns of the evaporator line, which is formed by a cover plate 17 with two small openings 18 is covered.
Die Figur 2d zeigt ebenfalls eine mögliche Maßnahme zur Rea¬ lisierung eines zwar gegenüber dem Vorratsbehälterinneren offenen, jedoch strömungstechnisch beruhigten Raumes 12"' mit einer auf die Wandung des Vorratsbehälters 1 entspre¬ chend aufgesetzten Kalotte 19, gegenüber einer Windung der Verdampferleitung 9. In jedem Fall muß sichergestellt sein, daß in den abgeschlossenen Raum 12 Flüssigkeit des Vorrats¬ behälters eindringen kann und dort bis zur Eisbildung auch verbleibt.FIG. 2d also shows a possible measure for realizing a space 12 ″ which is open to the interior of the storage container but has a fluidic calming, with a cap 19 correspondingly placed on the wall of the storage container 1, with respect to a winding of the evaporator line 9. In each In this case, it must be ensured that liquid from the storage container can penetrate into the closed space 12 and remains there until ice forms.
