Description
Die Erfindung betrifft eine Karbonisiervorrichtung gemäß dem Oberbegriff des Anspruchs 1 für den Haushaltsbereich zum Karbonisieren von Flüssigkeit, insbesondere von Wasser oder eines auf Wasserbasis hergestellten Getränkes, umfassend Wasserversorgungsmittel, bevorzugt einen Wasseranschluss zum Anschließen an eine Haus- (bzw. Fest-) Wasserleitung und/oder einen (wiederbefüllbaren) Wassertank sowie einen Karbonisierbehälter, dem mit CO2 versorgbare Karbonisiermittel, insbesondere eine Karbonisierkerze, zum Karbonisieren von Flüssigkeit zugeordnet, insbesondere in diesem angeordnet, sind.The invention relates to a Karbonisiervorrichtung according to the preamble of
Bekannte Karbonisiervorrichtungen für den Haushaltsbereich umfassen in der Regel eine austauschbare CO2-Druckflasche sowie ein Innengewinde zum Festlegen einer lösbaren Flasche, je nach Ausführungsform aus Glas oder Kunststoff. In dieser Flasche kann zu karbonisierendes Wasser aufgenommen werden, welches üblicherweise zuvor über einen Wasserhahn einer Festwasserleitung entnommen wurde. Dem zu karbonisierenden Wasser kann manuell Sirup zur Flavorisierung zugegeben werden. Für den Fall, dass der Nutzer ein gekühltes, karbonisiertes Getränk trinken möchte, muss er entweder vorher das zu karbonisierende Wasser oder das fertige Getränk im Anschluss an die Karbonisierung in einem Kühlschrank kühlen.Known household carbonators typically include a replaceable CO 2 pressure bottle and an internal thread for securing a detachable bottle, glass or plastic depending on the embodiment. In this bottle can be added to carbonating water, which was usually taken previously via a tap of a Festwasserleitung. The water to be carbonated can be manually added to the flavoring syrup. In the event that the user wishes to drink a chilled, carbonated beverage, he must first either cool the water to be carbonated or the finished beverage in a refrigerator after carbonation.

Die
Ausgehend von dem vorgenannten Stand der Technik liegt der Erfindung die Aufgabe zugrunde, eine verbesserte Karbonisiervorrichtung für den Haushalt anzugeben, mit welcher die Bereitstellung eines kühlen, karbonisierten Getränks möglich ist, wobei ein Anfrieren von zu kühlender Flüssigkeit, insbesondere Wasser, sicher vermieden werden soll.The
Based on the aforementioned prior art, the present invention seeks to provide an improved Karbonisiervorrichtung for the household, with which the provision of a cool, carbonated beverage is possible, with a freezing of liquid to be cooled, especially water, should be safely avoided.
Bevorzugt soll die Karbonisiervorrichtung den hygienischen Anforderungen Rechnung tragen.Preferably, the Karbonisiervorrichtung should take into account the hygienic requirements.
Diese Aufgabe wird hinsichtlich der Karbonisiervorrichtung mit den Merkmalen des Anspruchs 1 gelöst, d.h. bei einer gattungsgemäßen Karbonisiervorrichtung dadurch, dass dem Karbonisierbehälter zum Kühlen von darin befindlicher Flüssigkeit ein Latentkältespeicher zugeordnet ist, umfassend ein, bevorzugt synthetisches, Phasenwechselmaterial, welches zur Kältespeicherung die Enthalpie eines thermodynamischen Phasenwechsels von flüssig zu fest, insbesondere von flüssig zu kristallin, bei Unterschreiten einer Phasenwechseltemperatur nutzend ausgebildet ist, wobei diese Phasenwechseltemperatur auf eine Temperatur von oberhalb 0°C eingestellt bzw. das Phasenwechselmaterial so ausgebildet bzw. ausgewählt ist, dass die Phasenwechseltemperatur oberhalb des Gefrierpunktes von Wasser bei Normaldruck 1013 m/bar beträgt.This object is achieved with respect to the Karbonisiervorrichtung with the features of
Vorteilhafte Weiterbildungen der Erfindung sind in den Unteransprüchen angegeben. In den Rahmen der Erfindung fallen sämtliche Kombinationen aus zumindest zwei von in der Beschreibung, den Ansprüchen und/oder den Figuren offenbarten Merkmale.Advantageous developments of the invention are specified in the subclaims. All combinations of at least two features disclosed in the description, the claims and / or the figures fall within the scope of the invention.
Der Erfindung liegt der Gedanke zugrunde, die Karbonisiervorrichtung mit einem Latentkältespeicher auszustatten, der ein, bevorzugt synthetisches, Phasenwechselmaterial (Phasenübergangsmaterial) enthält, welches zur Kältespeicherung die Energie eines thermodynamischen Phasenwechsels (Phasenübergangs) von flüssig zu fest, insbesondere von flüssig zu kristallin, bei Unterschreiten eines Phasenwechseltemperatur von oberhalb 0°C nutzend ausgebildet ist, also oberhalb des Gefrierpunktes von Wasser, um somit sicher ein Frieren der zu kühlenden Flüssigkeit in der Getränkekühlvorrichtung, insbesondere bei Normalbedingungen, d.h. bei einem Atmosphärendruck von 1013 m/bar und einer Umgebungstemperatur von 20°C zu verhindern. Bei Phasenwechselmaterialien (PCM-Materialien) ist die latente Wärme, insbesondere die Schmelzwärme, wesentlich größer als die Wärme, die sie aufgrund ihrer normalen spezifischen Wärmekapazität (ohne den Phasenumwandlungseffekt) speichern kann. Dieser Phasenumwandlungseffekt wird vorliegend im Rahmen einer Haushaltsgetränkekarbonisiervorrichtung ausgenutzt, indem durch den Phasenübergang des Phasenwechselmaterials von fest zu flüssig der zu kühlenden Flüssigkeit ein erhebliches Maß an Wärmeenergie entzogen und diese somit gekühlt wird. Diese entzogene Wärmeenergie wird dem Latentkältespeicher erfindungsgemäß mit der Kühleinrichtung entzogen, bevorzugt derart, dass durch die Wirkung der Kühleinrichtung der bei der Kühlung der Flüssigkeit auftretende Phasenwechsel des Phasenwechselmaterials rückgängig gemacht wird, also das Phasenwechselmaterial zum Speichern der Kälteenergie wieder verfestigt wird. Wie erwähnt, handelt es sich bei dem Phasenwechselmaterial bevorzugt um ein synthetisches, insbesondere nicht auf Wasserbasis hergestelltes Phasenwechselmaterial, dessen Phasenwechseltemperatur auf eine Temperatur von oberhalb 0°C eingestellt ist. Ganz besonders bevorzugt enthält das Phasenwechselmaterial Paraffin bzw. ist auf Paraffinbasis ausgebildet.The invention is based on the idea to equip the Karbonisiervorrichtung with a Latentkältespeicher containing a, preferably synthetic, phase change material (phase change material), which for cold storage the energy of a thermodynamic phase change (phase transition) from liquid to solid, in particular from liquid to crystalline, falls below a phase change temperature of above 0 ° C is used, ie above the freezing point of water, thus ensuring a freezing of the liquid to be cooled in the beverage cooling device, in particular under normal conditions, ie at an atmospheric pressure of 1013 m / bar and an ambient temperature of 20 ° C to prevent. For phase change materials (PCM materials), the latent heat, especially the heat of fusion, is significantly greater than the heat that it can store due to its normal specific heat capacity (without the phase change effect). This phase transformation effect is exploited here in the context of a Haushaltsgetränkekarbonisiervorrichtung by withdrawn by the phase transition of the phase change material from solid to liquid of the liquid to be cooled, a significant amount of heat energy and this is thus cooled. This extracted heat energy is removed from the latent cold storage according to the invention with the cooling device, preferably such that is reversed by the action of the cooling device occurring during the cooling of the liquid phase change of the phase change material, ie the phase change material for Storing the cold energy is solidified again. As mentioned, the phase change material is preferably a synthetic phase change material, in particular not produced on the basis of water, whose phase change temperature is set to a temperature of above 0 ° C. Most preferably, the phase change material contains paraffin or is formed on paraffin-based.
Der Einsatz eines solchen Latentkältespeichers in Haushaltskarbonisiervorrichtungen für Getränke bringt erhebliche Vorteile mit sich. So wird aufgrund der speziellen Auswahl oder Einstellung des Phasenwechselmaterials mit einer Phasenwechseltemperatur von oberhalb 0°C ein Anfrieren von zu kühlender Flüssigkeit innerhalb der Karbonisiervorrichtung sicher vermieden, wie dieses auftreten würde, wenn an sich bekannte auf Wasser- bzw. Eisbasis arbeitende Kältespeichersysteme, wie diese beispielsweise in professionellen Zapfanlagen eingesetzt werden, anstelle des Latentkältespeichers verwendet würden.The use of such a latent cold storage in Haushaltskarbonisiervorrichtungen for drinks brings significant benefits. Thus, due to the particular selection or adjustment of the phase change material having a phase change temperature above 0 ° C, freezing of liquid to be cooled within the carbonator is safely avoided, as would occur if known cold water storage systems operating on water or ice, such as these For example, be used in professional dispensers, would be used instead of Latentkältespeichers.
Darüber hinaus ist der Latentkältespeicher pflegearm, d.h. das Phasenwechselmaterial muss vom Nutzer nicht ausgetauscht bzw. erneuert werden, wie dies bei bekannten Wasser- bzw. Eisbasiskältespeichern der Fall ist. Darüber hinaus ist der Latentkältespeicher wartungsfrei. Durch die Integration eines Latentkältespeichers in eine Haushalts-Karbonisiervorrichtung kann dem Nutzer auf komfortable und einfach zu bedienende Weise ein auf eine Temperatur von unter 10°C, noch weiter bevorzugt unter 8°C gekühltes, karbonisiertes Getränk bereitgestellt werden. Ganz besonders bevorzugt ist der Latentkältespeicher derart ausgebildet, dass mit der erfindungsgemäßen Karbonisiervorrichtung Getränke auf eine Temperatur zwischen 1°C und 8°C, ganz besonders bevorzugt zwischen 2°C und 6°C, kühlbar sind, insbesondere ausgehend von einer Ursprungswassertemperatur, beispielsweise von einer typischen Raumtemperatur von 20°C oder 22°C oder einer Wassertemperatur in einem Wasserleitungsnetz, beispielsweise zwischen 9°C und 16°C.In addition, the Latentkältespeicher is low maintenance, ie the phase change material must not be replaced or renewed by the user, as is the case with known water or Eisbasiskältespeichern. In addition, the latent cold storage is maintenance-free. By integrating a latent cold storage into a household carbonator, the user may be provided in a convenient and easy to use way with a carbonated beverage cooled to a temperature of below 10 ° C, more preferably below 8 ° C. Most preferably, the latent cold storage is designed such that with the carbonator according to the invention drinks to a temperature between 1 ° C and 8 ° C, most preferably between 2 ° C and 6 ° C, can be cooled, in particular starting from a source water temperature, for example a typical room temperature of 20 ° C or 22 ° C or a water temperature in a water supply network, for example between 9 ° C and 16 ° C.
Bevorzugt ist der Karbonisierbehälter als Druckbehälter ausgebildet und/oder angesteuert, wobei der Druck im Behälter während und/oder nach der Karbonisierung bevorzugt zwischen 2 bar und 12 bar, bevorzugt zwischen 3,5 bar und 7 bar, beträgt. Wie später noch erläutert werden wird, dient in Weiterbildung der Erfindung der Behälterdruck zum Ausleiten von karbonisierter Flüssigkeit in Richtung zu einem Auslass, bevorzugt unter Verzicht auf entsprechende elektromotorische Fördermittel, wie einer Pumpe.Preferably, the Karbonisierbehälter is designed and / or controlled as a pressure vessel, wherein the pressure in the container during and / or after the carbonization preferably between 2 bar and 12 bar, preferably between 3.5 bar and 7 bar, is. As will be explained later, in a further development of the invention, the container pressure is used for discharging carbonized liquid in the direction of an outlet, preferably without corresponding electromotive conveying means, such as a pump.
Wie später noch erläutert werden wird, stellt die Karbonisiervorrichtung (über den Latentkältespeicher) gekühltes, karbonisiertes Wasser zur Verfügung, wobei der Wärmeübergang der zu kühlenden Flüssigkeit, insbesondere Wasser, in den Latentkältespeicher mittels eines Durchflusswärmetauschers und/oder in dem Karbonisierbehälter entzogen wird, der, wie noch erläutert werden wird, bevorzugt von dem Latentkältespeicher umgeben ist. Erfindungsgemäß ist vorgesehen, dass die Karbonisiervorrichtung neben gekühltem karbonisiertem Getränk, gekühltes, nicht karbonisiertes Getränk, insbesondere stilles Wasser, an einem Auslass bereitstellt, welches diesem bevorzugt unter Umgehung des Karbonisierbehälters zugeführt wird. Unabhängig davon, ob die Kühlvorrichtung ausschließlich karbonisiertes Getränk oder zusätzlich auch stilles Getränk ausgeben kann, ist in Weiterbildung der Erfindung vorgesehen, die Karbonisiervorrichtung mit einer Flavorisiereinrichtung auszustatten, um mit Geschmack versehenes, d.h. flavorisiertes, karbonisiertes Getränk (und ggf. stilles, flavorisiertes Getränk) ausgeben zu können, indem Wasser in der Karbonisiervorrichtung in Kontakt gebracht wird mit entsprechendem Getränkesubstrat, beispielsweise durch Injizieren von Wasser in eine Getränkesubstratkapsel und/oder Injizieren von Getränkesubstrat, insbesondere Konzentrat in das Wasser, insbesondere mittels einer Einspritzeinrichtung.As will be explained later, the carbonator (via the latent cold store) provides cooled, carbonated water, wherein the heat transfer of the liquid to be cooled, in particular water, is withdrawn into the latent cold storage by means of a flow heat exchanger and / or in the carbonator, which, as will be explained, is preferably surrounded by the Latentkältespeicher. According to the invention, it is provided that, in addition to cooled carbonated beverage, the carbonating device provides cooled, non-carbonated beverage, in particular still water, at an outlet which is preferably supplied to the latter, bypassing the carbonating container. Regardless of whether the cooling device can spend exclusively carbonated beverage or additionally also still drink, is provided in development of the invention to equip the Karbonisiervorrichtung with a Flavorisiereinrichtung to flavored, ie flavored, carbonated beverage (and possibly still, flavored beverage) by contacting water in the carbonator with appropriate beverage substrate, for example, by injecting water into a beverage substrate capsule and / or injecting beverage substrate, in particular concentrate into the water, in particular by means of an injection device.
Besonders bevorzugt ist es, wenn die Karbonisiermittel derart ausgebildet sind, dass mit diesen die Flüssigkeit auf einen CO2-Anteil von über 3g/l, insbesondere zwischen 4g/l, vorzugsweise zwischen 4g/l und 15g/l, ganz besonders bevorzugt zwischen 5g/l und 15g/l, noch weiter bevorzugt zwischen 5g/l und 9g/l CO2, karbonisierbar ist.It is particularly preferred if the carbonating agents are designed such that with these the liquid to a CO 2 content of about 3g / l, in particular between 4g / l, preferably between 4g / l and 15g / l, most preferably between 5g / l and 15g / l, more preferably between 5g / l and 9g / l CO 2 , is carbonizable.
Besonders zweckmäßig ist es, wenn die Phasenwechseltemperatur des Phasenwechselmaterials von flüssig zu fest, insbesondere bei 1013 m/bar mindestens 0,1°C beträgt und bevorzugt zwischen 0,1°C und 10°C gewählt ist. Besonders bevorzugt ist es, wenn die Phasenwechseltemperatur zwischen 0,1°C und 6°C, noch weiter bevorzugt zwischen 0,1°C und 5°C, ganz besonders bevorzugt zwischen 0,5°C und 2°C gewählt ist.It is particularly useful if the phase change temperature of the phase change material from liquid to solid, in particular at 1013 m / bar is at least 0.1 ° C and is preferably selected between 0.1 ° C and 10 ° C. It is particularly preferred if the phase change temperature between 0.1 ° C and 6 ° C, even more preferably between 0.1 ° C and 5 ° C, most preferably between 0.5 ° C and 2 ° C is selected.
Optimal für den Einsatz in den hier interessierenden Haushaltsvorrichtungen ist es, wenn das Phasenwechselmaterial nicht frei vorliegt, sondern an eine Polymerstruktur gebunden ist. Diese Technologie verhindert ein freies fließendes Phasenwechselmaterial nach seinem Phasenübergang in die flüssige Phase. Ganz besonders bevorzugt ist eine Ausführungsform, bei der das Phasenwechselmaterial, insbesondere aufgrund der Anbindung an einer Polymerstruktur spritzgießbar oder gießbar ist, wozu insbesondere das Trägerpolymer aufgeschmolzen werden muss. Bevorzugt liegt die Schmelztemperatur über 20°C, insbesondere über 50°C, noch weiter bevorzugt über 100°C, ganz besonders bevorzugt über 110°C, beispielsweise zwischen 120°C und 170°C. Unabhängig davon, ob das Phasenwechselmaterial aufgrund einer Polymerstrukturanbindung oder aufgrund einer anderen Technologie zu einem Formkörper formbar ist, ist es bevorzugt, wenn das, insbesondere polymergebundene Phasenwechselmaterial, also eine das Phasenwechselmaterial enthaltende Zusammensetzung, die neben dem Phasenwechselmaterial einen weiteren Bestandteil, wie ein Trägerpolymer umfasst, als formstabiler Formkörper vorliegt, der formstabil ist bis mindestens zu einer Temperatur von 20°C, noch weiter bevorzugt von mindestens 50°C, ganz besonders bevorzugt von mindestens 100°C, noch weiter bevorzugt von mindestens 110°C.It is optimal for use in the household devices of interest here if the phase change material is not free, but is bound to a polymer structure. This technology prevents free flowing phase change material after its phase transition into the liquid phase. Very particular preference is given to an embodiment in which the phase change material, in particular due to the connection to a polymer structure, is injection-moldable or castable, for which purpose in particular the carrier polymer has to be melted. The melting temperature is preferably above 20 ° C., in particular above 50 ° C., even more preferably above 100 ° C., very particularly preferably above 110 ° C., for example between 120 ° C. and 170 ° C. Regardless of whether the phase change material is moldable due to a polymer structure connection or due to another technology, it is preferred if the, in particular polymer bound phase change material, ie a composition containing the phase change material, in addition to the phase change material comprises a further constituent such as a carrier polymer is present as a dimensionally stable shaped body which is dimensionally stable up to at least a temperature of 20 ° C, even more preferably of at least 50 ° C, most preferably of at least 100 ° C, even more preferably of at least 110 ° C.
Die Ausbildung des Phasenwechselmaterials bzw. der Zusammensetzung (insbesondere zusammen mit einem Trägermaterial) als Formkörper, hat insbesondere für Haushaltsgeräte erhebliche Vorteile - so kann beispielsweise auf spezielle Abdichtungen verzichtet werden, da das Phasenwechselmaterial auch in der flüssigen Phase nicht davon fließen kann. Darüber hinaus kann die Herstellung des Formkörpers bzw. des Kältespeichers durch übliche Kunststoffformprozesse, wie Spritzgießen oder Gießen erfolgen, insbesondere durch Umspritzen oder Umgießen einer Durchflussleitung für einen Durchflusswärmetauscher und/oder des dann gleichzeitig als Kühlbehälter dienenden Karbonisierbehälter. Zudem bietet diese Ausgestaltung den Vorteil, dass große Wärmeübergangsflächen, wie Rippenstrukturen, besonders einfach und vollflächig mit dem Latentkältespeicher umgeben werden können.The formation of the phase change material or of the composition (in particular together with a carrier material) as a shaped body has considerable advantages, in particular for household appliances - for example, special seals can be dispensed with since the phase change material can not flow away even in the liquid phase. In addition, the production of the shaped body or of the cold storage can be carried out by conventional plastic molding processes, such as injection molding or casting, in particular by encapsulation or encapsulation of a flow line for a flow heat exchanger and / or then simultaneously serving as a cooling tank Karbonisierbehälter. In addition, this design offers the advantage that large heat transfer surfaces, such as rib structures, particularly simple and full-surface can be surrounded with the Latentkältespeicher.
Der Karbonisierbehälter dient in erster Linie der Karbonisierung von Wasser oder eines daraus hergestellten, flavorisierten Getränks und kann, was bevorzugt ist, gleichzeitig zum Kühlhalten und/oder zum Kühlen von darin aufgenommener Flüssigkeit dienen, wenn, wie noch erläutert werden wird, der Karbonisierbehälter gleichzeitig als Kühlbehälter ausgebildet ist, der zumindest abschnittsweise von dem Latentkältespeicher umgeben ist oder indem der Latentkältespeicher zumindest abschnittsweise in den Behälter hineinragt. Bevorzugt umfasst der Karbonisierbehälter ein Innenvolumen bzw. weist ein Aufnahmevolumen von Flüssigkeit zwischen 200 mm und 3000 mm, ganz besonders bevorzugt zwischen 400 mm und 1500 mm, noch weiter bevorzugt zwischen 500 mm und 1000 mm auf. Besonders bevorzugt beträgt ein Durchmesser des Kühlbehälters über 5 cm.The carbonator vessel serves primarily to carbonize water or a flavored beverage made therefrom, and may, as is preferred, simultaneously serve to hold and / or cool liquid received therein, as will be explained later, as the carbonator vessel simultaneously Cooling container is formed, which is at least partially surrounded by the Latentkältespeicher or by the Latentkältespeicher protrudes at least partially into the container. Preferably, the Karbonisierbehälter comprises an inner volume or has a receiving volume of liquid between 200 mm and 3000 mm, most preferably between 400 mm and 1500 mm, even more preferably between 500 mm and 1000 mm. Particularly preferred is a diameter of the cooling tank over 5 cm.
Zur Bereitstellung des für eine Karbonisierung benötigen CO2 in der Karbonisiervorrichtung ist es von Vorteil, wenn die Karbonisiermittel mit einem CO2-Druckspeicher verbunden sind, der entweder fest in der Karbonisiervorrichtung verbaut oder besser austauschbar an dieser festlegbar ist. Bei dem CO2-Druckspeicher handelt es sich bevorzugt um eine CO2-Druckgasflasche, die noch weiter bevorzugt zum Wiederbefüllen austauschbar ist.In order to provide the CO 2 required for carbonization in the carbonator, it is advantageous if the carbonizers are connected to a CO 2 pressure accumulator, which is either permanently installed in the carbonator or better exchangeable at this fixable. The CO 2 pressure accumulator is preferably a CO 2 compressed gas cylinder, which is even more preferably replaceable for refilling.
Wie bereits angedeutet ist es besonders bevorzugt, wenn der Karbonisierbehälter gleichzeitig als Kühlbehälter zum Kühlen und/oder Kühlhalten von Wasser und/oder einem im Rahmen der Karbonisiervorrichtung auf Wasserbasis hergestellten Getränkes ausgestaltet ist. Hierzu ist der Karbonisierbehälter bevorzugt zumindest abschnittsweise von dem Latentkältespeicher umgeben, insbesondere umgossen oder umspritzt.As already indicated, it is particularly preferred if the carbonating container is designed at the same time as a cooling container for cooling and / or keeping water cool and / or a beverage produced in the context of the water-based carbonating device. For this purpose, the Karbonisierbehälter is preferably at least partially surrounded by the Latentkältespeicher, in particular cast or overmoulded.
Zusätzlich oder alternativ kann der Latentkältespeicher zumindest abschnittsweise in dem Karbonisierbehälter angeordnet sein, beispielsweise axial oder radial in diesen hineinragen.Additionally or alternatively, the latent cold storage can be arranged at least in sections in the Karbonisierbehälter, for example, project axially or radially in this.
Als besonders zweckmäßig hat sich eine Ausgestaltung der Karbonisiervorrichtung herausgestellt, bei der der Karbonisierbehälter zu Kühlzwecken einen Metallmantel, insbesondere einen Leichtmetalllegierungsmantel, wie einen Aluminiumlegierungsmantel aufweist, der zumindest abschnittsweise, bevorzugt vollumfänglich von dem Latentkältespeicher umgeben ist, insbesondere umgossen oder umspritzt ist, wobei der Kältespeicher bevorzugt wiederum von einem Wärmedämmmaterial umgeben ist, wobei es sich bei dem Wärmedämmmaterial beispielsweise um ein Kunststoffschaummaterial handeln kann und/oder um ein spritzbares Material.Particularly expedient, an embodiment of the Karbonisiervorrichtung has been found in which the Karbonisierbehälter for cooling purposes, a metal shell, in particular a light metal alloy shell, such as an aluminum alloy jacket, which is at least partially, preferably completely surrounded by the Latentkältespeicher, in particular cast or overmolded, the cold storage preferably in turn is surrounded by a thermal insulation material, wherein the thermal insulation material may be, for example, a plastic foam material and / or a sprayable material.
Als besonders vorteilhaft hat es sich nun herausgestellt, wenn dem Metallmantel mindestens eine, bevorzugt monolithisch (einteilig) mit dem Metallmantel ausgebildete oder den Metallmantel wärmeleitend kontaktierende Kälteübergangskontaktfläche zugeordnet ist, die wärmeleitend von der Kühleinrichtung, insbesondere einem thermoelektrischen Kühlelement, kontaktiert ist. Bevorzugt ist die Kälteübergangskontaktfläche an einem Axial- und/oder Radialfortsatz vorgesehen, der den den Metallmantel umgebenden Latentkältespeicher durchsetzt und bevorzugt zumindest abschnittweise auch das bevorzugt vorgesehene Wärmedämmmaterial, um dann von außen die Kühleinrichtung anschließen bzw. kontaktieren zu können.To be particularly advantageous, it has now been found that at least one, preferably monolithic (one-piece) formed with the metal shell or the metal shell thermally conductive contacting cold junction contact surface is the metal shell, which is thermally conductive of the cooling device, in particular a thermoelectric cooling element, contacted. The cold junction contact surface is preferably provided on an axial and / or radial extension, which penetrates the latent cold storage surrounding the metal jacket and preferably at least in sections also the preferably provided thermal insulation material in order to connect or contact the cooling device from the outside.
Im Rahmen der vorliegenden Offenbarung ist in erster Linie die Rede von einem als Metallmantel ausgebildeten Mantel des Kühl- oder Karbonisierbehälters. Hierbei handelt es sich jedoch lediglich um ein bevorzugtes Ausführungsbeispiel. Denkbar ist auch der Einsatz alternativer, wärmeleitender Materialien, wie Kunststoffmaterialien, die, falls diese vorgesehen werden, auch eine fakultative Leitung eines Durchflusswärmetauschers beinhalten können, beispielsweise durch Umspritzen. Dies bedeutet, dass sämtliche Offenbarungsstellen, an denen von einem Metallmantel die Rede ist auch im Sinne eines Mantels allgemein, d.h. unabhängig von der Materialwahl, zu verstehen sind.In the context of the present disclosure, the term primarily refers to a jacket of the cooling or carbonizing container formed as a metal jacket. However, this is only a preferred embodiment. Also conceivable is the use of alternative, heat-conducting Materials, such as plastic materials, which, if provided, may also include optional ducting of a flow heat exchanger, such as by overmolding. This means that all revelation points that are referred to by a metal shell in the sense of a coat generally, ie regardless of the choice of material to understand.
Zur Gewährleistung eines guten Wärmeübergangs zwischen Latentkältespeicher und Kühlbehälter bzw. Karbonisierbehälter hat es sich als besonders vorteilhaft herausgestellt, den Metallmantel mit einer konturierten Außenfläche zu versehen, in die das Phasenwechselmaterial (Kältespeichermedium) ragt, was insbesondere durch Umspritzen oder Umgießen dieser konturierten Außenfläche mit dem Latentkältespeichermaterial bzw. dem bevorzugt polymergebundenen Phasenwechselmaterial realisiert ist. Wie erwähnt, ist es zusätzlich oder alternativ zur Ausbildung des Karbonisierbehälters als zumindest abschnittsweise von dem Latentkältespeicher begrenzten Kühlbehälters zur Kühlung von Flüssigkeit während einer Ruhephase möglich und bevorzugt, einen dem Latentkältespeicher zugeordneten Durchflusswärmetauscher vorzusehen, um Wasser und/oder ein daraus hergestelltes flavorisiertes Getränk zu kühlen. Dieser Durchflusswärmetauscher umfasst bevorzugt eine Durchflussleitung, die mit dem Latentkältespeicher wirkverbunden ist, um mit diesem der durch die Durchflussleitung strömenden Flüssigkeit Wärmeenergie entziehen zu können.To ensure a good heat transfer between Latentkältespeicher and cooling tank or Karbonisierbehälter, it has been found to be particularly advantageous to provide the metal shell with a contoured outer surface into which the phase change material (cold storage medium) protrudes, which in particular by encapsulation or encapsulation of this contoured outer surface with the latent cold storage material or the preferably polymer-bound phase change material is realized. As mentioned, it is additionally or alternatively to the formation of the Karbonisierbehälters as at least partially limited by the Latentkältespeicher cooling tank for cooling liquid during a rest phase possible and preferred to provide the Latentkältespeicher associated flow heat exchanger to cool water and / or a flavored beverage prepared therefrom , This flow heat exchanger preferably comprises a flow line which is operatively connected to the latent cold storage in order to be able to extract thermal energy from the liquid flowing through the flow line with it.
Ganz besonders bevorzugt ist eine Kombination aus Durchflusswärmetauscher und als Kühlbehälter ausgebildeten Karbonisierbehälter, die sich eines gemeinsamen oder unterschiedlicher Latentkältespeicher(s) bedienen, wobei bevorzugt auch die im Durchflusswärmetauscher vorgekühlte Flüssigkeit, insbesondere Wasser dem als Kühlbehälter ausgebildeten Karbonisierbehälters zugeführt und/oder an diesem vorbei unmittelbar in Richtung eines Auslasses geleitet wird.Very particularly preferred is a combination of flow heat exchanger and designed as a cooling tank Karbonisierbehälter, the use of a common or different Latentkältespeicher (s), preferably also in the flow heat exchanger pre-cooled liquid, in particular water designed as a cooling tank Supplied carbonation and / or passed to this past immediately in the direction of an outlet.
Insbesondere beim Vorsehen einer Kombination aus Durchflusswärmetauscher und als Kühlbehälter ausgebildetem Karbonisierbehälter ist es von Vorteil, wenn der Durchflusswärmetauscher, eine, bevorzugt gewendelte, Flüssigkeitsleitung (Durchflussleitung) umfasst, die zumindest abschnittsweise innerhalb der Karbonisierbehälterwandung verläuft, insbesondere in diese eingegossen ist, beispielsweise für den bevorzugten Fall der zumindest abschnittsweisen Ausbildung der Behälterwandung aus Metallgussmaterial. Zusätzlich oder alternativ verläuft die Flüssigkeitsleitung des Durchflusswärmetauschers außerhalb der Karbonisierbehälterwandung in einem Bereich zwischen dem Karbonisierbehälter und dem Latentkältespeicher oder innerhalb des Latentkältespeichers. Bei den zuvor erwähnten Realisierungsmöglichkeiten entzieht der Latentkältespeicher sowohl der durch den Durchflusswärmetauscher strömenden Flüssigkeit als auch der im Karbonisierbehälter aufgenommenen Flüssigkeit Wärmeenergie.In particular, when providing a combination of flow heat exchanger and designed as a cooling tank Karbonisierbehälter, it is advantageous if the flow heat exchanger, a, preferably coiled, liquid line (flow line) includes at least partially extends within the Karbonisierbehälterwandung, in particular cast into this, for example for the preferred Case of at least partially forming the container wall made of metal casting material. Additionally or alternatively, the liquid line of the flow heat exchanger outside the Karbonisierbehälterwandung in a range between the Karbonisierbehälter and the Latentkältespeicher or within the Latentkältespeichers. In the aforementioned implementation possibilities, the latent cold storage removes heat energy both from the liquid flowing through the flow heat exchanger and from the liquid taken up in the carbonizing tank.
Besonders zweckmäßig ist es, wenn die Karbonisiervorrichtung mit, bevorzugt elektromotorischen, Fördermitteln, insbesondere in Form einer Pumpe, beispielsweise einer Schwingankerpumpe oder einer Rotationskolbenpumpe oder alternativ zu einer Pumpe mit einer Förderzentrifuge, zum Fördern von Wasser von den Wasserversorgungsmitteln in Richtung zu dem Latentkältespeicher, insbesondere in den Karbonisierbehälter und/oder durch einen fakultativen Durchflusswärmetauscher, aufweist.It is particularly expedient if the Karbonisiervorrichtung with, preferably electromotive, funding, in particular in the form of a pump, such as a vibrating tank pump or a rotary piston pump or alternatively to a pump with a delivery centrifuge for conveying water from the water supply means in the direction of the latent cold storage, in particular in the Karbonisierbehälter and / or by an optional flow heat exchanger having.
Bevorzugt beträgt ein erzeugbarer Fördervolumenstrom der Fördermittel zwischen 200ml/min und 1000 ml/min, ganz besonders bevorzugt zwischen 250ml/min und 800ml/min. Für den bevorzugten Fall der Realisierung des Karbonisierbehälters als Kühlbehälter ist in Weiterbildung der Erfindung eine die Fördermittel ansteuernde Niveauregelung vorgesehen, um für ein gleichbleibendes Füllniveau Sorge zu tragen, welches bevorzugt zwischen 200ml und 3000 ml, ganz besonders bevorzugt zwischen 400ml und 1500 ml, noch weiter bevorzugt zwischen 500 ml und 1000 ml, beträgt.Preferably, a producible delivery volume flow of the conveying means is between 200 ml / min and 1000 ml / min, very particularly preferably between 250 ml / min and 800 ml / min. For the preferred case of the realization of the Karbonisierbehälters as a cooling container is in the development of The invention provides a level control which activates the conveying means, in order to ensure a constant filling level, which is preferably between 200 ml and 3000 ml, very particularly preferably between 400 ml and 1500 ml, even more preferably between 500 ml and 1000 ml.
Grundsätzlich ist es möglich, im Karbonisierbehälter karbonisierte Flüssigkeit aus dem Karbonisierbehälter zu einem Getränkeauslass mittels einer Pumpe oder dgl. elektromotorisch betriebenen Fördermittel zu befördern. Bevorzugt ist jedoch eine Ausführungsform, bei der karbonisierte Flüssigkeit aus dem Karbonisierbehälter mittels CO2-Druck, insbesondere aus dem vorerwähnten Druckspeicher zu dem Auslauf, insbesondere durch ein manuell oder automatisiert betätigbares Auslassventil förderbar ist, wodurch auf eine ansonsten notwendige Austragspumpe verzichtet werden kann.In principle, it is possible to convey carbonated liquid from the carbonating container to a beverage outlet in the carbonating container by means of a pump or the like, by electric motor driven conveying means. However, preferred is an embodiment in which carbonated liquid from the Karbonisierbehälter by means of CO 2 pressure, in particular from the aforementioned accumulator to the outlet, in particular by a manually or automatically operable outlet valve can be conveyed, which can be dispensed with an otherwise necessary discharge pump.
Wie eingangs bereits angedeutet, ist es grundsätzlich möglich, dass mit der Karbonisiervorrichtung lediglich karbonisiertes Wasser (ohne Geschmackszugabe und ggf. zusätzlich gekühltes stilles Wasser) bereitgestellt wird. Besonders zweckmäßig ist es jedoch in Weiterbildung der Erfindung, die Karbonisiervorrichtung mit einer Flavorisiereinrichtung auszustatten, mittels der stilles und/oder karbonisiertes Wasser mit Getränkesubstrat in Kontakt bringbar ist, beispielsweise in an sich bekannter Weise durch das Vorsehen einer Injektionseinrichtung zum Injizieren von Wasser in bzw. zum Durchleiten von Wasser durch eine Getränkesubstrateinheit, insbesondere einer Getränkesubstratkapsel und/oder das Vorsehen einer bevorzugt eine Einspritzpumpe umfassenden Einrichtung zum Einspritzen von Getränkesubstrat, insbesondere Konzentrat in das Wasser, insbesondere während des Durchflusses und/oder in den Karbonisierbehälter hinein.As already indicated, it is basically possible that with the carbonator only carbonated water (without added flavor and possibly additionally cooled still water) is provided. However, it is particularly useful in a further development of the invention to equip the Karbonisiervorrichtung with a Flavorisiereinrichtung, by means of the still and / or carbonated water with beverage substrate can be brought into contact, for example in a conventional manner by providing an injection device for injecting water into or for passing water through a beverage substrate unit, in particular a beverage substrate capsule and / or the provision of a device preferably comprising an injection pump for injecting beverage substrate, in particular concentrate into the water, in particular during the flow and / or in the Karbonisierbehälter inside.

Die Vorrichtung 1 umfasst Wasserversorgungsmittel 2, hier in Form eines nachfüllbaren Wassertanks, der zum Wiederauffüllen entnehmbar angeordnet ist. Zusätzlich oder alternativ kann die Vorrichtung 1 mit einem Anschluss zum Anschließen an eine Festwasseranschlussleitung versehen sein. Die Wasserversorgungsmittel 2 umfassen in dem konkreten Ausführungsbeispiel ein Kopplungsventil 3, umfassend eine Rückschlagventilanordnung, um eine Entnahme des Wasserbehälters zu Reinigungs- und Wiederbefüllzwecken zu ermöglichen.The

Die Fördermittel 5 dienen der Versorgung 1 eines Behälters 6 mit Wasser. Der Behälter 6 ist in dem gezeigten Ausführungsbeispiel gleichzeitig als Kühlbehälter und Karbonisierbehälter ausgestaltet. Die den Fördermitteln 5 nachgeordnete Wasserversorgungsleitung (Druckseite) mündet in einen das Behälterinnenvolumen umgebenden, hier gewendelt ausgeführten Durchflusswärmetauscher 7 und kann dann als stilles Wasser, d.h. in nicht karbonisierter Form über ein ersten Auslassventil 8 zu einem Auslass 9 in ein Getränkebehältnis 10, insbesondere ein Glas oder eine Tasse oder einen Krug strömen. Das erste Auslassventil 8 befindet sich in einer Auslassleitung 11 für stilles Wasser.The conveying means 5 serve to supply 1 of a
Wie dem Fluidschema zu entnehmen ist, teilt sich eine Ausgangsleitung 12 des Durchlasswärmetauschers 7 auf, in die vorerwähnte Auslassleitung für stilles Wasser 11 sowie eine Befüllleitung 13 mit Befüllventil 14 zum Befüllen des Behälters 6 mit zu karbonisierendem Wasser. Der Behälter 6 ist zum Einhalten eines konstanten Füllniveaus mit einer angedeuteten Niveauregelung 15 ausgestattet, über die die Fördermittel 5 entsprechend geregelt werden.As can be seen from the fluid diagram, an
Dem Behälter 6 sind Karbonisiermittel 16, bevorzugt umfassend eine Karbonisierkerze zugeordnet, die über eine Druckleitung 17 mit CO2 aus einem CO2-Druckspeicher 18 der Vorrichtung 1 versorgbar sind, um das Wasser zu karbonisieren.The

Der Latentkältespeicher 19 hat in dem konkreten Ausführungsbeispiel zwei Aufgaben. Zum einen kühlt er das im Durchfluss durch den Durchflusswärmetauscher 7 strömende nicht karbonisierte Wasser, welches dann in gekühlter Form über die Auslassleitung 11 zum Auslass 9 geführt wird. Für den Fall, dass dieses Wasser in einem Befüllbetriebszustand über die Befüllleitung 13 in den Behälter 6 zur späteren Aufkarbonisierung strömt ist das Wasser bereits vorgekühlt. Gleichzeitig dient der Latentkältespeicher 19 aufgrund der Anordnung um die Behälterwandung herum zur Kühlung des innerhalb des Behälters 6 befindlichen Wassers vor und/oder während und/oder nach einem Aufkarbonisierungsschritt. Das karbonisierte Wasser kann über eine Auslassleitung 20 mit einem zweiten Auslassventil 21 zum Auslass 9 geleitet und dort in das Getränkebehältnis 10 gezapft werden. Selbstverständlich ist es alternativ zu dem Vorsehen eines gemeinsamen Auslasses 9 möglich, separate Auslässe für karbonisiertes und stilles Wasser vorzusehen.
- Unabhängig davon, Bei der Auswahl des Phasenwechselmaterials ist es wesentlich, dass dieses so eingestellt bzw. ausgestaltet ist, dass mit diesem die zu kühlende Flüssigkeit, hier Wasser bei einer Umgebungstemperatur von 20°C nicht friert, d.h. also eine Eisbildung vermieden wird, was insbesondere bei zu kühlenden nichtalkoholischen Flüssigkeiten dadurch sichergestellt werden kann, dass die Phasenwechseltemperatur (Phasenübergangstemperatur) des Phasenwechselmaterials (Phasenübergangsmaterials) oberhalb von 0°C liegt.
- Regardless, in the selection of the phase change material, it is essential that this is set or designed so that it does not freeze the liquid to be cooled, here water at an ambient temperature of 20 ° C, ie, ice formation is avoided, which in particular in non-alcoholic liquids to be cooled, it can be ensured that the phase change temperature (phase transition temperature) of the phase change material (phase change material) is above 0 ° C.
