Abstract
Description
Die vorliegende Erfindung betrifft eine Ausgabevorrichtung für ein Kältegerät zur Ausgabe einer Flüssigkeit, insbesondere von gekühltem Wasser. Derartige Ausgabevorrichtungen werden in zunehmendem Maße, häufig kombiniert mit einem automatischen Eisbereiter, in Kältegeräte eingebaut. Sie umfassen herkömmlicherweise eine Flüssigkeitsleitung, an der ein Tank und ein Schaltventil zum Steuern der Ausgabe von Flüssigkeit aus dem Tank angeordnet sind. Meist ist die Leitung an das Trinkwassernetz eines Gebäudes anschließbar, um aus dem Tank entnommenes Wasser automatisch nachzufüllen.The The present invention relates to an output device for a refrigerator for dispensing a liquid, in particular cooled Water. Such dispensers are increasingly being combined, often combined with an automatic ice maker, installed in refrigerators. They include conventionally a liquid line, on a tank and a switching valve for controlling the output of liquid are arranged from the tank. Mostly the line is to the drinking water network a building connected, to automatically top up with water taken from the tank.
Herkömmlicherweise ist der Auslass, an dem die Flüssigkeitsleitung endet, ein offenes Ende eines abwärts gerichteten Rohres. In einem solchen Rohr bleibt häufig nach dem Abzapfen von Wasser zunächst ein Rest zurück, der erst mit einer gewissen Verzögerung abfließt. Wenn der Behälter, in den abgezapft worden ist, zu dem Zeitpunkt bereits vom Auslass entfernt worden ist, verteilt sich das Wasser unkontrolliert.traditionally, is the outlet to which the fluid line ends, an open end of a down pipe. In such a pipe remains frequent after tapping off water first a rest back, the first with a certain delay flows. If the container, into which has already been tapped, at the time already from the outlet has been removed, the water is distributed uncontrollably.
Zur Tropfenbildung am Auslass kann es auch kommen, wenn Wasser im Tank bis kurz über den Gefrierpunkt abgekühlt wird. Sobald nämlich eine Temperatur von 4°C unterschritten wird, dehnt sich das Wasser im Tank wieder aus, und dabei verdrängtes Wasser tritt am Auslass aus.to Dripping at the outlet can also occur if there is water in the tank until just above the Freezing point cooled becomes. As soon as a Temperature of 4 ° C falls below, the water in the tank expands again, and thereby displaced Water exits at the outlet.
Ein weiteres Problem, das mit der Abkühlung von Wasser im Tank zusammenhängt, ist die Volumenabnahme, die bei Abkühlung oberhalb von 4°C auftritt. Sie führt dazu, dass, wenn frisch eingefülltes Wasser im Tank abkühlt, Luft am Auslass eingesogen wird. Wenn diese den Tank erreicht, ist sie daraus schwierig wieder zu beseitigen.One Another problem associated with the cooling of water in the tank is the volume decrease, the cooling occurs above 4 ° C. she leads to that, when freshly filled water cooling in the tank, Air is sucked in at the outlet. When it reaches the tank is make them difficult to remove.
Aufgabe der vorliegenden Erfindung ist, eine Ausgabevorrichtung, insbesondere für gekühltes Wasser, für ein Kältegerät zu schaffen, bei der das Problem des Nachtropfens wenn nicht behoben, so doch zumindest gelindert ist.task The present invention is an output device, in particular for chilled water, for a To create a refrigeration device when the problem of dripping if not resolved, at least at least alleviated.
Die Aufgabe wird dadurch gelöst, dass an einer Ausgabevorrichtung mit einer an einem Auslass endenden Flüssigkeitsleitung, an der ein Schaltventil und ein Tank für die Flüssigkeit angeordnet sind, der Auslass mit einem Lippenventil versehen ist.The Task is solved by that on an output device having one end at an outlet Liquid line, on which a switching valve and a tank for the liquid are arranged, the outlet provided with a lip valve.
Das Lippenventil bildet einen flexiblen Engpass, den Wasser, welches nach einem Abzapfvorgang in einem Rohrabschnitt oberhalb des Lippenventils drucklos steht, nicht zu überwinden vermag. Da das Lippenventil unter einem an der stromaufwärtigen Seite anliegenden Unterdruck sperrt, ist es auch wirksam, um ein Zurückfließen von Luft in die Leitung zu verhindern, insbesondere, wenn der Tank zwischen dem Auslass und dem Schaltventil angeordnet ist.The Lip valve forms a flexible bottleneck, the water which after a tapping operation in a pipe section above the lip valve unpressurized stands, can not be overcome can. Because the lip valve is under one on the upstream side adjacent negative pressure locks, it is also effective to a backflow of To prevent air in the pipe, especially if the tank is between the outlet and the switching valve is arranged.
Vorzugsweise ist an dem Tank ein Zuflussanschluss oberhalb eines Abflussanschlusses angeordnet. Dadurch ist es möglich, kaltes Wasser, das sich im Tank in Bodennähe sammelt, abzuzapfen, während gleichzeitig oben warmes Wasser nachfließt, ohne dass sich die unterschiedlich temperierten Wassermassen vermischen. Bei einem solchen Tank ist es besonders wichtig, mit Hilfe des Lippenventils das Zurückströmen von Luft in den Tank zu verhindern, da es schwierig ist, aus einem solchen Tank die Luft wieder zu beseitigen.Preferably is at the tank an inflow port above a drain port arranged. This makes it possible cold tap water that collects in the tank near the bottom, while at the same time warm water flows in, without that mix the different temperature water masses. In such a tank, it is particularly important to use the lip valve Backflow of To prevent air from entering the tank as it is difficult to get out of such a tank Tank to eliminate the air again.
Um zu verhindern, dass das Lippenventil unter einem zu starken stromaufwärtigen Unterdruck kollabiert, ist der Tank vorzugsweise reversibel komprimierbar. So wird der Unterdruck, der im Tank auftreten kann, begrenzt und das Lippenventil geschützt.Around to prevent the lip valve from collapsing under excessive upstream vacuum, the tank is preferably reversible compressible. That is how it works Vacuum, which can occur in the tank, limits and the lip valve protected.
