Description

Die vorliegende Erfindung betrifft eine Vorrichtung zum Temperieren von in Gefäßen wie insbesondere Flaschen befindlichen Flüssigkeiten, wie insbesondere von Getränken.The present invention relates to a device for tempering in vessels such as liquids in particular bottles, such as in particular of drinks.

Die Erfindung geht davon aus, daß es zwar möglich ist, Flüssigkeiten z.B. mit Hilfe von Mikrowellen sehr schnell zu erwärmen, daß das Abkühlen jedoch relativ viel Zeit erfordert. So dauert etwa das Kühlen von in Flaschen befindlichen Getränken in einem Kühlschrank von Raumtemperatur auf Trinktemperatur (∼ 8 °C) mehrere Stunden, und in einem Tiefkühlschrank immer noch mindestens eine Stunde.The invention assumes that it is possible to use liquids e.g. with help of microwaves to heat very quickly, but the cooling relatively much Takes time. For example, it takes time to cool bottled drinks in a refrigerator from room temperature to drinking temperature (∼ 8 ° C) several Hours, and still in the freezer for at least an hour.

Aus dem Stand der Technik sind Flaschenkühler bekannt, die entweder Eiswasser als Kühlmedium verwenden (DE-PS 252 782) oder aber thermoelektrische Kühlungen, die der Umgebung bei entsprechender Polung Wärme entziehen bzw. gegenüberliegend abgeben, sog. Peltierelemente (GB 844 652; DE 34 13 031 A1, DD 80 856).Bottle coolers are known from the prior art, which either ice water use as cooling medium (DE-PS 252 782) or thermoelectric Cooling that draws heat from the environment with appropriate polarity or dispense opposite, so-called Peltier elements (GB 844 652; DE 34 13 031 A1, DD 80 856).

Nachteilig ist bei den thermoelektrischen Flaschenkühlern, daß die Zeit der Temperaturabsenkung des Flascheninhaits relativ lang ist, da die Flaschen von Luft umgeben sind. Die Kühlung geschieht dabei über einen Ventilator (DD 80 856) oder durch Wärmeleitung über eine Metallplatte, auf der die Flasche steht (GB 844 652). In der DE-PS 252 782 muß zur Aufrechterhaltung der gewünschten niedrigen Temperatur Eis nachgefüllt werden, die Flasche steht dabei in einem Einsatz aus für Wasser undurchlässigen biegsamen Stoff, dieser ist nur zur Verwendung bestimmter Flaschendurchmesser geeignet.A disadvantage of thermoelectric bottle coolers is that the time for lowering the temperature the bottle contents is relatively long because the bottles are out of air are surrounded. The cooling is done by a fan (DD 80 856) or by heat conduction over a metal plate on which the bottle stands (GB 844 652). In DE-PS 252 782 must maintain the desired low temperature ice, the bottle is in one Use of flexible material impermeable to water, this is only for use certain bottle diameter suitable.

Die vorliegende Erfindung hat sich demgegenüber die Aufgabe gestellt, eine Vorrichtung zu schaffen, mit deren Hilfe das Abkühlen oder Erwärmen von Flascheninhalt in von Peltierelementen beaufschlagten Behältnissen möglich ist, wobei der gesteigerte Wärmeübergang weitgehend unabhängig vom Durchmesser der Flaschen gewährleistet bleiben soll.In contrast, the present invention has as its object a device to create, with the help of cooling or heating bottle contents is possible in containers loaded by Peltier elements, the increased heat transfer largely independent of the diameter of the bottles should be guaranteed.

Die Lösung dieser Aufgabe gelingt mit einer Vorrichtung zum Temperieren von in Gefäßen, insbesondere von in Flaschen befindlichen Getränken, welche die Merkmale des Hauptanspruches aufweist. Vorteilhafte Ausgestaltungen finden sich in den Unteransprüchen.This problem is solved with a device for tempering in Vessels, especially of bottled beverages, which the Features of the main claim. Find advantageous configurations themselves in the subclaims.

Die Drahtbügel sind umfaßt von einem lose an diesen anliegenden Folienstrumpf und das Gehäuse ist mit einem Kühlmedium befüllbar. In einer Ausnehmung der Wandung des Gehäuses ist als Kühlung ein Peltierelement angeordnet, das eine Wärmeübertragungsfläche und eine Gegenfläche aufweist, wobei die Wärmeübertragungsfläche von dem Fluid umspült und die Gegenfläche belüftet ist. Unter Fluid im Sinne der vorliegenden Erfindung werden dabei schüttfähige Materialien, wie Granulate, vorzugsweise jedoch Flüssigkeiten verstanden.The wire brackets are surrounded by a loosely attached film stocking and the housing can be filled with a cooling medium. In a recess of the Wall of the housing is arranged as a cooling Peltier element, the one Has heat transfer surface and a counter surface, the heat transfer surface washed by the fluid and the counter surface is ventilated. Under In the context of the present invention, fluid can be used as pourable materials, understood as granules, but preferably liquids.

Durch die erfindungsgemäße Ausgestaltung wird eine intensive, nahezu vollflächige Temperierung der Behältnisse erreicht, wobei das verwendete Kühlmedium, vorzugsweise Wasser, den Temperaturausgleich zwischen dem Peltierelement wegen der gegenüber Luft wesentlich höheren Wärmeleitfähigkeit stark beschleunigt. Gleichwohl werden die Behältnisse jedoch nicht benetzt, das Fluid ist vollständig von den Behältnissen und auch der Umgebungsluft separiert, so daß auch eine Verkeimung ausgeschlossen ist, gegebenenfalls lassen sich dem für den Wärmetransport verwendeten Medium entsprechende Desinfektionsmittel zugeben.The configuration according to the invention makes an intensive, almost full-surface Tempering of the containers reached, the cooling medium used, preferably water, the temperature compensation between the Peltier element because of the much higher thermal conductivity compared to air accelerates. Nevertheless, the containers are not wetted, the fluid is completely separated from the containers and also from the ambient air, so that germs are also excluded, if necessary, the Appropriate disinfectants used for heat transfer admit.

Durch die Drahtbügel wird erreicht, daß der wasserundurchlässige Folienstrumpf derart beabstandet wird, daß sich die Gefäße in diesen von oben leicht einschieben lassen. Darüber hinaus fixieren die über Stege verbundenen Bügel den Folienstrumpf gegen dessen Auftrieb am Gehäuseboden.The wire hanger ensures that the waterproof film stocking is spaced such that the vessels slide into them easily from above to let. In addition, the brackets connected via webs fix the Foil stocking against its buoyancy on the case bottom.

Vorteilhaft weist der Boden des Kühlbeckens eine Ausnehmung auf, in welchen die Stege eingreifen. Diese vorteilhaft als V-Nut gestaltete Ausnehmung gewährleistet, daß die Drahtbügel gegen ein Verschieben oder Verrutschen gesichert sind und so beim Einstellen oder der Entnahme der Getränkebehälter in der nahezu senkrechten Position verbleiben.The bottom of the cooling basin advantageously has a recess in which engage the webs. This recess, which is advantageously designed as a V-groove, ensures that the wire bracket is secured against shifting or slipping are and so when setting or removing the beverage container in the near vertical position remain.

Der Folienstrumpf hat gegenüber den Gefäßen ein Übermaß, so daß hinsichtlich ihrer Abmessung verschieden große Behältnisse temperiert werden können, wobei der hydrostatische Druck dafür sorgt, daß sich die Folie eng und großflächig an die Gefäßwandung anlegt. Dadurch wird zum einen ein guter Wärmekontakt gewährleistet. Zum anderen werden so die Gefäße in dem Behältnis gehalten und dem Auftrieb insbesondere bei teilentleerten Gefäßen entgegengewirkt.The film stocking has an excess compared to the vessels, so that with regard to their dimensions can be tempered containers of different sizes, wherein The hydrostatic pressure ensures that the film is tight and large to the wall of the vessel. On the one hand, this creates good thermal contact guaranteed. On the other hand, the vessels are kept in the container and counteracting buoyancy, particularly in the case of partially emptied vessels.

Die Wärmeübertragungsfläche ist dabei wie auch die Gegenfläche vergrößert und weist Rippen auf, so daß die Leistungsfähigkeit des Peltierelements gesteigert wird.The heat transfer surface is enlarged, as is the counter surface has ribs so that the performance of the Peltier element is increased becomes.

Vorteilhaft ist dabei, daß nach Umpolung des Peltierelements dieses auch zur Erwärmung des Übertragungsfluids und überdies des Gefäßinhaltes verwendet werden kann, um damit z.B. auch Heißgetränke bereitstellen zu können.It is advantageous that after reversing the polarity of the Peltier element, this also for heating of the transmission fluid and also the contents of the vessel can be used can, e.g. to be able to provide hot drinks too.

Um von der Gegenfläche Wärme abzuführen wird vorgeschlagen, dieser in an sich bekannter Weise ein Gebläse zuzuordnen. Dieses ist vorzugsweise leiselaufend bzw. schallisoliert in der Vorrichtung angeordnet. In order to dissipate heat from the counter surface, it is suggested that it be in assign a fan in a known manner. This is preferably quiet or arranged soundproofed in the device.

Das Gebläse ruht zur Schallisolierung vorzugsweise in einer Auskleidung aus Schaumkunststoff wie z.B. Polyurethan.For sound insulation, the fan preferably rests in a lining Foam plastic such as Polyurethane.

Weiterhin weist die Wandung insbesondere in der Ausführung aus Schaumkunststoff Schraubeinsätze zur Befestigung von Einbauten wie insbesondere des Befestigungsringes der Halteplatte für den Folienstrumpf und des Peltierelements, wobei zwischen dem Peltierelement und der dieses tragenden Wand eine Dichtung angeordnet ist, die den Kühlmedienraum von der Gebläseseite abtrennt.Furthermore, the wall has, in particular, the design made of foam plastic Screw inserts for fastening internals such as the Fastening ring of the holding plate for the film stocking and the Peltier element, a seal between the Peltier element and the wall supporting it is arranged, which separates the cooling medium space from the blower side.

Es wird vorgeschlagen, auf dem Gehäuse bzw. dessen oberem Rand eine Pumpe zu befestigen, über welche Druckluft in das Gefäß eingebracht werden kann, um über ein Steigleitung und einen Auslauf die enthaltene Flüssigkeit ausbringen zu können, ohne das Gefäß entnehmen zu müssen. Die Pumpe kann äquivalent auch einen Druckgasanschluß aufweisen oder elektrisch betreibbar sein, insbesondere ist sie handbetrieben.It is proposed to have a pump on the housing or its upper edge to fasten, via which compressed air can be introduced into the vessel in order to Dispense the liquid contained via a riser and an outlet can without having to remove the vessel. The pump can be equivalent also have a compressed gas connection or be electrically operated, in particular it is manually operated.

Um beim Pumpen Leerhub zu vermeiden, ist in der Steigleitung nahe ihrem oberen Ende ein insbesondere federbelastetes Rückschlagventil angeordnet, das nach dem Beenden des Pumpvorganges den Rückfluß der anstehenden Flüssigkeit verhindert.To avoid idle stroke when pumping, the riser is near its top Arranged a particularly spring-loaded check valve, the after the pumping process has ended, the reflux of the liquid present prevented.

Die Feder des Ventils kann eine veränderbare Federspannung aufweisen, auf diese Weise kann im Gasraum oberhalb der Flüssigkeit im Gefäß ein gewünschter Überdruck aufrechterhalten werden, der ein unerwünschtes Ausgasen insbesondere von CO2 mindert.The spring of the valve can have a variable spring tension, in this way a desired overpressure can be maintained in the gas space above the liquid in the vessel, which reduces undesired outgassing, in particular of CO 2 .

Von besonderem Vorteil ist die vorliegende Erfindung für großvolumige Getränkeflaschen, insbesondere z.B. für CO2-haltige Erfrischungsgetränke oder Bier. Der Flascheninhalt wird wegen der hohen Leistungsfähigkeit der Peltierelemente und dem erfindungsgemäß gewährleisteten sehr hohen Wärmeübergang zum einen überraschend schnell gekühlt - ca. 15 Minuten genügen in der Regel für eine Temperaturabfall von bis zu über 10 °C - zum anderen muß der Flascheninhalt bei Entnahme nicht bewegt werden, was zu einer deutlichen Verminderung an CO2-Verlusten führt.The present invention is particularly advantageous for large-volume beverage bottles, in particular for example for CO 2 -containing soft drinks or beer. The bottle contents are cooled surprisingly quickly on the one hand because of the high performance of the Peltier elements and the very high heat transfer guaranteed according to the invention - about 15 minutes are usually sufficient for a temperature drop of up to over 10 ° C - on the other hand the bottle contents do not have to be moved when removed become, which leads to a significant reduction in CO 2 losses.

Der Pumpenkopf besitzt vorzugsweise eine Aufnahme für den Flaschenhals, der z.B. mit einem Gewinde ausgestattet ist, in das die Flasche einschraubbar ist. Dabei kann eine Pumpe auch für die Druckversorgung mehrerer Flaschen dienen, die Ausläufe weisen dabei Absperrorgane auf, die wahlweise geöffnet werden.The pump head preferably has a receptacle for the bottle neck, the e.g. is equipped with a thread into which the bottle can be screwed. One pump can also be used to supply pressure to several bottles, the spouts have shut-off devices that can be opened optionally.

Auf dem Gehäuse kann die Pumpe z.B. mit Hilfe eines Bajonettverschlusses gehalten sein, das Peltierelement ist insbesondere durch einen einstellbaren Thermostaten geregelt.On the housing the pump can e.g. held with the help of a bayonet catch be, the Peltier element is particularly adjustable Thermostats regulated.

Anhand der beiliegenden Figuren wird die vorliegende Erfindung erläutert.The present invention is explained on the basis of the attached figures.

  • Figure 2 shows the holder of the film stocking and
  • Figure 3 is a plan view of this.

    • Figur 1 zeigt das Gehäuse 2 der Vorrichtung, das in seinem Inneren ein Becken 20 aus Schaumkunststoff aufweist, welches mit Kühlmedium 13 in gewünschter Menge gefüllt ist.
    Das Becken 20 weist seitlich eine Ausnehmung 9 auf, in die eine Peltierelement als Kühlung 3 eingefügt ist, dieses wird über Schraubeinsätze in der Beckenwandung gehalten. Dabei ragen die Rippen der Wärmeübertragungsfläche 11 in das Beckeninnere, d.h. sie sind von dem Kühlmedium, vorzugsweise Wasser, umspült, wobei das Fluid natürlich bei Umpolung des Peltierelements Wärme aufnimmt und überträgt.     Figure 1 shows the housing 2 of the device, which has in its interior a basin 20 made of foam plastic, which is filled with cooling medium 13 in the desired amount.
    The basin 20 has a recess 9 on the side, into which a Peltier element as cooling 3 is inserted, which is held in the basin wall by means of screw inserts. The ribs of the heat transfer surface 11 protrude into the interior of the pool, ie they are surrounded by the cooling medium, preferably water, the fluid naturally absorbing and transferring heat when the polarity of the Peltier element is reversed.

    In der Beckenwandung 10 ist ein Spacer 21 angeordnet, der von einem O-Ring 22 umgeben ist und die Luftkammer 23 gegen das Fluid 13 abdichtet.A spacer 21 is arranged in the basin wall 10 and is supported by an O-ring 22 is surrounded and seals the air chamber 23 against the fluid 13.

    Die eigentliche Peltierfläche 24 liegt am Spacer 21 an, seine gegenüberliegende Seite ist mit den Rippen der Gegenfläche 12 verbunden und vom Gebläse 25 beaufschlagt, welches in Halterippen 26 aus Schaumkunststoff eingefügt ist. Die Luftkammer 23, durch ein Abdeckblech 33 geschlossen ist, umgibt somit Gebläse und Peltierelement, sie weist eine Luftzu- und eine Luftableitung auf, über welche sie mit der Umgebungsluft verbunden ist.The actual Peltier surface 24 lies against the spacer 21, its opposite one Side is connected to the ribs of the counter surface 12 and acted upon by the blower 25, which is inserted into retaining ribs 26 made of foam plastic. The Air chamber 23, which is closed by a cover plate 33, thus surrounds fans and Peltier element, it has an air inlet and an air outlet, via which it is connected to the ambient air.

    Auf einem Vorsprung 27 am oberen Beckenteil liegt ein Befestigungsring 28 auf, der ebenfalls aus Schaumkunststoff gefertigt und über Schraubeinsätze 14 mit dem Becken verschraubt sein kann. Dieser Befestigungsring 28 dichtet gegen das Kühlmedium 13 ab.A fastening ring 28 rests on a projection 27 on the upper basin part, which is also made of foam plastic and with screw inserts 14 the basin can be screwed. This mounting ring 28 seals against that Cooling medium 13 from.

    Der Haltering 28 umschließt den oberen Rand des Folienstrumpfes 8, der in das Becken 20 hinabhängt und von den Drahtbügeln 7 auf Abstand gehalten wird. Die Drahtbügel 7 sind fußseitig über Stege 7' zusammengefaßt und fixieren den Folienstrumpf 8 gegen dessen Auftrieb am Boden des Beckens 20.The retaining ring 28 encloses the upper edge of the film stocking 8, which in the Basin 20 hangs down and is kept at a distance from the wire brackets 7. The Wire clips 7 are combined on the foot side via webs 7 'and fix the Foil stocking 8 against its buoyancy at the bottom of the pool 20.

    Der Beckenboden weist eine Ausnehmung 29 auf, in welche die Stege 7' der Bügel 7 eingreifen, die somit gegen ein Verrutschen oder Verschieben beim Einstellen oder der Entnahme der Getränkebehälter 1 gesichert sind. The pelvic floor has a recess 29 into which the webs 7 'of the bracket 7 intervene, thus preventing slipping or shifting when adjusting or the removal of the beverage container 1 are secured.

    Halteplatte 4 und Haltering 28 sind zum Einstellen einer Flasche durchbrochen-Öffnung 5, wobei vorteilhaft der Haltering in die Halteplatte integriert ist.Retaining plate 4 and retaining ring 28 are perforated for opening a bottle opening 5, wherein the retaining ring is advantageously integrated into the holding plate.

    In den Folienstrumpf 8 ist ein Gefäß 1 (Flasche) eingestellt, wobei der Druck des Kühlmediums 13 den Folienstrumpf eng an die Gefäßwandung schmiegt und derart eine Wärmeübertragung durch Wärmeleitung ermöglicht. Gleichzeitig wird so auch dem Auftrieb des Getränkebehältnisses entgegengewirkt.A vessel 1 (bottle) is set in the film stocking 8, the pressure of the Cooling medium 13 hugs the film stocking close to the vessel wall and such enables heat transfer through heat conduction. At the same time also counteracted the buoyancy of the beverage container.

    Das Fluid 13 ist somit vom Gefäß getrennt, es kann lange Zeit im Becken verbleiben und braucht grundsätzlich nicht ausgetauscht zu werden. Es kann chemische Zusätze zur Erhöhung der Wärmeleitung enthalten.The fluid 13 is thus separated from the vessel, it can remain in the basin for a long time and basically does not need to be replaced. It can be chemical Includes additives to increase heat conduction.

    Figur 2 zeigt den über die im wesentlichen senkrechten Drahtbügel 7 gezogenen Folienstrumpf 8. Dieser weist gegenüber dem (radialen) Abstand der Drahtbügel 7 ein Übermaß auf, so daß auch Gefäße unterschiedlicher Durchmesser eingestellt werden können. Die Drahtbügel 7, welche über Stege 7' fußseitig zusammengefaßt sind, halten den Folienstrumpf auseinander und fixieren diesen gegen dessen Auftrieb am Boden, so daß die Gefäße leicht eingeschoben werden können. Außen steht am Folienstrumpf das Kühlmedium an, das die Folie nach innen drückt und eine große Kontaktfläche zu den Gefäßen schafft. Es sind mindestens drei Drahtbügel erforderlich. FIG. 2 shows the film stocking 8 drawn over the essentially vertical wire brackets 7. This has an excess compared to the (radial) spacing of the wire brackets 7, so that vessels of different diameters can also be set. The wire brackets 7, which are combined on the foot side via webs 7 ', hold the film stocking apart and fix it against its buoyancy on the floor, so that the vessels can be easily inserted. On the outside of the film stocking is the cooling medium, which presses the film inwards and creates a large contact area with the vessels. At least three wire brackets are required.

    Figur 3 zeigt die mit der Halteplatte 4 verbundenen und über die Stege 7' zusammengefaßten Drahtbügel 7, die hier kreuzförmig als vier Abstandshalter angeordnet sind. Der Folienstrumpf 8 ist durch den hydrostatischen Druck eingebeult, in den Zwischenraum 34 kann mühelos eine Flasche oder ein anderes Gefäß eingeschoben werden. Zusätzlich ist es natürlich möglich, den oberen Rand des Folienstrumpfes an der Halteplatte 4 bzw. dem darunterliegenden Befestigungsring (28, Fig. 1) zu befestigen, um so eine große Einschuböffnung zu erhalten. Mittig besitzt die Halteplatte 4 die Öffnung 5. FIG. 3 shows the wire brackets 7 connected to the holding plate 4 and combined via the webs 7 ', which are arranged here in a cross shape as four spacers. The film stocking 8 is dented by the hydrostatic pressure, a bottle or another vessel can be easily inserted into the intermediate space 34. In addition, it is of course possible to fasten the upper edge of the film stocking to the holding plate 4 or the fastening ring (28, FIG. 1) underneath, in order to obtain a large insertion opening. The holding plate 4 has the opening 5 in the center.
