Abstract
Description
Die Erfindung betrifft eine Vorrichtung zum keimfreien Zapfen von Getränken, z.B. von stillem Wasser, von mit CO2 oder O2 angereichtertem oder versetztem Wasser, von Säften, von Milch usw., mit einem in einem Gehäuse angeordneten oder ausgebildeten Flüssigkeitskanal, mit einem Anschluß zum Zuführen des Getränkes und einer Abgabeöffnung zum Abgeben des Getränkes.The invention relates to a device for the sterile dispensing of beverages, for example still water, of water enriched or mixed with CO 2 or O 2 , of juices, of milk, etc., with a liquid channel arranged or formed in a housing, with a connection to Feeding the beverage and a discharge opening for dispensing the beverage.
Bei der Trinkwasseraufbereitung bzw. Tafelwasseraufbereitung im Bereich von Einzelverbrauchern (Haushalt) oder Großverbrauchern (Krankenhäusern, Betrieben) ist entscheidend, dass das gezapfte bzw. abgegebene Wasser dem Verbraucher keimfrei zur Verfügung gestellt wird. Insbesondere besteht die Gefahr, dass bei unregelmäßiger Benutzung, aber auch bei häufiger Inanspruchnahme derartiger Anlagen am freien Ende der Zapfstelle ein oder auch mehrere Wassertropfen hängen bleiben, die Anlaß zu einer Keimbildung geben können, oder aber, dass der Rand des Auslasses von Zeit zu Zeit Keime aus der Umgebung aufnimmt, die z.B. von Benutzern der Anlage oder aus der Umgebung stammen. Derartige Probleme treten jedoch nicht nur bei der Trinkwasser- bzw. der Tafelwasseraufbereitung auf, sondern generell bei Getränken, die nicht in keimfreier Umgebung gezapft werden.For drinking water treatment or table water treatment in the area of individual consumers (Household) or large consumers (hospitals, companies) is crucial that the tapped or dispensed water is germ-free for the consumer Is made available. In particular, there is a risk that if used irregularly, but also with frequent use of such systems at the free end one or more drops of water get stuck at the tap, which gives rise to one Nucleation can give or that the edge of the outlet from time to time Time absorbs germs from the environment, e.g. from users of the plant or from the environment. However, such problems do not only occur with drinking water or table water treatment, but generally for drinks that are not in aseptic environment can be tapped.
Aus der DE 43 36 248 C2 ist ein Filtergerät zum Filtern von Wasser, zum Regenerieren des Filters und zum Desinfizieren des Filters im Haushaltsbereich bekannt, bei dem ein gesintertes Aktivkohlefilter in der einen Durchflußrichtung im Filterbetrieb benutzt wird und in der entgegengesetzten Richtung das Rückspülmittel in Form von heißem Wasserdampf zur Regeneration und Desinfektion des Filters hindurchgepreßt wird. Hierbei wird der Volumenstrom des Filtergerätes klein gehalten, um eine lange Verweildauer des zu filternden Wassers im Filtermedium zu gewährleisten und eine optimale Filterwirkung zu erzielen. Mit einer derartigen Methode wird erreicht, dass die Filterregenerierung und die Desinfektion ohne Zerlegen des Filtergerätes und ohne Wechsel des Filtermediums erreicht wird. Nachteilig ist hierbei, dass die Desinfektion kontinuierlich durchgeführt und Dampf am Gerät bereitgestellt werden muß.DE 43 36 248 C2 describes a filter device for filtering water, for regeneration of the filter and for disinfecting the filter in the household sector, in which a sintered activated carbon filter used in one flow direction in filter operation and in the opposite direction the backwashing agent in the form of hot Water vapor is pressed through for regeneration and disinfection of the filter. Here, the volume flow of the filter device is kept small in order to ensure a long residence time to ensure the water to be filtered in the filter medium and an optimal Achieve filter effect. With such a method it is achieved that the Filter regeneration and disinfection without disassembling the filter device and without Change of filter medium is achieved. The disadvantage here is that disinfection carried out continuously and steam must be provided on the device.
Des weiteren ist aus der DE 197 44 490 A1 eine Trinkwasseraufbereitungsanlage mit Aktivkohlefilter und Sterilfilter bekannt, bei der der Aktivkohlefilter durch Austausch des Filtermediums gereinigt und der Sterilfilter durch hindurchgeleiteten Wasserdampf desinfiziert bzw. regeneriert wird. Der Wasserdampf wird durch eine Heizeinrichtung am Sterilfilter erzeugt. Hierbei wird vorgeschlagen, den Zapfhahn der Anlage mit Wasserdampf, der durch den Zapfhahn geleitet wird, regelmäßig zu reinigen, wobei die Heizung vorzugsweise als Heizpatrone ausgebildet ist. Auch diese Methode hat den Nachteil, dass an der Zapfstelle Wasserdampf erzeugt bzw. durch den Zapfhahn geleitet werden muß, der anschließend kondensiert und in Form von Wassertröpfchen am Zapfhahnausgang zurückbleibt, so dass erneut die Gefahr einer Bekeimung besteht.Furthermore, from DE 197 44 490 A1 a drinking water treatment plant is included Activated carbon filter and sterile filter known in which the activated carbon filter by replacement of the filter medium cleaned and the sterile filter through water vapor passed through disinfected or regenerated. The water vapor is through a heater generated on the sterile filter. It is proposed here to tap the system tap with steam, which is passed through the tap to clean regularly, the Heating is preferably designed as a heating cartridge. This method also has the Disadvantage that water vapor is generated at the tap or passed through the tap must be condensed and then in the form of water droplets on Tap outlet remains, so that there is again the risk of germination.
Aufgabe der Erfindung ist, eine gattungsgemäße Trinkwasseraufbereitungsanlage so zu verbessern, dass eine einfache, preiswerte und effektive Entkeimung am austrittsseitigen Ende der Zapfstelle erreicht wird.The object of the invention is to create a generic drinking water treatment plant improve that a simple, inexpensive and effective disinfection on the outlet side End of the tap is reached.
Diese Aufgabe wird dadurch gelöst, dass die Abgabeöffnung bzw. der Bereich der Abgabeöffnung des Flüssigkeitskanals elektrisch beheizt wird.

Sie kann ferner als Manschette oder dgl. ausgebildet sein, die am Flüssigkeitsrohrende befestigt wird. Alternativ kann die Heizvorrichtung in das Rohrende, z.B. in unmittelbarer Nähe der Abflußöffnung, in die Leitungswand eingebaut und integriert sein. Der Flüsigkeitskanal im Bereich der Abgabeöffnung wird in regelmäßigen Abständen während der Zeit, in der kein Getränk gezapft wird, kurzzeitig auf eine so hohe Temperatur aufgeheizt, z.B. höher als 80°C, dass eine Keimbildung und damit ein Eindringen von Keimen durch die Abgabeöffnung in den nach innen anschließenden Teil des Flüssigkeitskanales verhindert wird, wobei die Keime bei anhaltender Nichtbenutzung der Anlage oder aber durch Einfluß von außen entstehen können. Vor allen Dingen tritt die Keimbildung an Wassertröpfchen auf, die am Umfangsrand der Öffnung der Flüssigkeitsleitung bestehen bleiben. Durch den Aufheizvorgang erfolgt eine Erwärmung des Endbereiches der Flüssigkeitsleitung bzw. der anhaftenden Wassertröpfchen bis auf eine Temperatur, bei der entstehende Keime abgetötet werden.

Above all, nucleation occurs Water droplets on the peripheral edge of the opening of the liquid line stay. The heating process heats up the end area of the Liquid line or the adhering water droplets to a temperature at the resulting germs are killed. Steam is not formed here.
Die Heizvorrichtung ist vorzugsweise als Heizspule ausgebildet, die mit Niedervoltspannung von z.B. 24 V gespeist wird; die Stromstärke wird so gewählt, dass eine Aufheizung der Innenseite des Rohrstückes, des Ringes, der Manschette oder dgl. auf ca. 85 - 125°C erreicht wird, also eine Temperatur, bei der der Aufbau eines Biofilmes an der Innenwand des Wasserauslaßstutzens sicher vermieden wird, so dass an der Auslaufstelle eine Keimsperre erreicht wird, die verhindert, dass Keime am Auslauf entstehen und bei der nächsten Wasserentnahme mit in das Trinkwasser gelangen oder sich nach innen bewegen können.The heating device is preferably designed as a heating coil with low voltage from e.g. 24 V is supplied; the current is chosen so that a Heating up the inside of the pipe section, the ring, the cuff or the like 85 - 125 ° C is reached, i.e. a temperature at which a biofilm builds up on the inner wall of the water outlet nozzle is avoided, so that on the Spout is a germ barrier that prevents germs from spilling arise and get into the drinking water with the next water withdrawal or can move inwards.
