Description

Kältegerät mit Wasserleitung Refrigerating appliance with water pipe
Die vorliegende Erfindung betrifft ein Kältegerät mit einem wenigstens einen Innenraum umschließenden wärmeisolierenden Gehäuse und einer Wasserleitung, die eine Wand des Gehäuses kreuzt, um zum Beispiel einen in dem Innenraum untergebrachten Eisbereiter oder eine Zapfstelle mit Wasser zu versorgen.The present invention relates to a refrigerator having a heat-insulating housing enclosing at least one internal space, and a water pipe crossing a wall of the housing to, for example, supply water to an ice maker or a tap located in the interior.
Aus DE 10 2005 057 137 A1 ist ein derartiges Kältegerät bekannt, bei dem in die Wasserleitung ein Wasserfilter eingefügt ist. Das Wasserfilter befindet sich entweder in einem Sockelbereich des Kältegeräts, außerhalb von dessen Isolationsschicht, oder innerhalb von dieser in engem thermischem Kontakt mit dem Innenraum. Bei der ersten Ausgestaltung tritt das Problem auf, dass gleichzeitig Abwärme erzeugende Vorrichtungen wie etwa Verdichter und/oder Verflüssiger in dem Sockelbereich untergebracht sind, und diese den Wasserfilter erwärmen. Eine warme Umgebung fördert jedoch das Wachstum von Keimen in dem Filter und verkürzt so die Zeit, die dieser betrieben werden kann, ohne ausgetauscht oder regeneriert zu werden. Eine Anbringung des Wasserfilters in engem thermischem Kontakt mit dem Innenraum hingegen ist nur praktikabel, wenn dieser mit Gewissheit keine Temperaturen unter 00C annimmt. Ein enger thermischer Kontakt des Filters mit dem umgebenden Innenraum führt außerdem dazu, dass jedes Mal, wenn warmes Frischwasser von außen in den Filter nachströmt, dessen Umgebung im Innenraum erwärmt wird, was die Haltbarkeit von dort untergebrachtem Kühlgut beeinträchtigen kann.From DE 10 2005 057 137 A1, such a refrigeration device is known in which a water filter is inserted into the water line. The water filter is located either in a base region of the refrigeration device, outside of its insulating layer, or within this in close thermal contact with the interior. In the first embodiment, there is a problem that waste heat generating devices such as compressors and / or condensers are accommodated in the base area at the same time and they heat the water filter. However, a warm environment promotes the growth of germs in the filter and thus shortens the time that it can be operated without being exchanged or regenerated. An attachment of the water filter in close thermal contact with the interior, however, is only practicable, if it assumes with certainty no temperatures below 0 0 C. A close thermal contact of the filter with the surrounding interior also means that each time warm fresh water from the outside flows into the filter, the environment is heated in the interior, which may affect the durability of stored therein refrigerated goods.
Aufgabe der vorliegenden Erfindung ist, ein Kältegerät mit einer eine Gehäusewand kreuzenden Wasserleitung und einer in der Wasserleitung gebildeten Kammer anzugeben, bei der Wasser in der Kammer kühl gehalten werden kann, ohne dass dies zu einer unzweckmäßigen Erwärmung von der Kammer benachbarten Bereichen des Innenraums führt.The object of the present invention is to provide a refrigeration device having a water pipe crossing a housing wall and a chamber formed in the water pipe, in which water in the chamber can be kept cool, without this leading to inappropriate heating of the chamber adjacent areas of the interior.
Die Aufgabe wird gelöst, indem bei einem Kältegerät der oben angegebenen Art die Kammer in eine Isolationsschicht der Wand eingebettet ist. So nimmt das Wasser in derThe object is achieved by the chamber is embedded in an insulating layer of the wall in a refrigeration device of the type specified above. So does the water in the
Kammer in stationärem Zustand eine Temperatur an, die zwischen derjenigen desChamber in a stationary state, a temperature between that of the
Innenraums und der Umgebung liegt. Dies ermöglicht eine Anbringung der Kammer auch an einem Gefriergerät, ohne dass das Innere der Kammer gefrieren muss. Derjenige Teil der Isolationsschicht, der zwischen der Kammer und dem Innenraum liegt, verhindert zwar nicht, dass das Wasser seine Wärme an den Innenraum abgibt, doch kann er den Wärmeübergang so weit verlangsamen, dass dieser Wärmeeintrag nur noch einen kleinen Anteil des Gesamtwärmeeintrags in den Innenraum ausmacht. Somit kommt es in der Umgebung der Kammer auch zu keiner Erwärmung des Innenraums, die die Haltbarkeit von dort untergebrachtem Kühlgut beeinträchtigen könnte.Interior and the surrounding area. This allows attachment of the chamber as well on a freezer, without the interior of the chamber having to freeze. Although that part of the insulation layer that lies between the chamber and the interior does not prevent the water from giving off its heat to the interior, it can slow down the heat transfer to such an extent that this heat input only accounts for a small proportion of the total heat input into the interior accounts. Thus, it comes in the vicinity of the chamber and no warming of the interior, which could affect the shelf life of refrigerated goods housed there.
Wenn das Gehäuse in an sich bekannter Weise einen Korpus und eine an den Korpus angelenkte Tür umfasst, ist die Wand, in der die wassergefüllte Kammer untergebracht ist, vorzugsweise Teil des Korpus. Insbesondere kann sie eine Seitenwand, eine Decke, ein Boden oder, bei einem Kältegerät mit zwei Innenräumen, auch eine Trennwand zwischen diesen sein.If the housing in a conventional manner comprises a body and hinged to the body door, the wall, in which the water-filled chamber is housed, preferably part of the body. In particular, it may be a side wall, a ceiling, a floor or, in a refrigerator with two interiors, also a partition wall between them.
Zweckmäßig ist eine Unterbringung der Kammer in einer Decke des Kältegeräts insbesondere deshalb, weil, falls die dem Innenraum zugewandte Unterseite der Kammer auf unter 00C abkühlt, daran abgekühltes Wasser in der Kammer so lange aufsteigt, anstatt zu gefrieren, bis der gesamte Kammerinhalt auf 00C abgekühlt ist. Falls hingegen die Unterseite der Kammer wärmer als 4°C ist, bildet sich im Inneren der Kammer eineIt is expedient to accommodate the chamber in a ceiling of the refrigerator, in particular, because, if the underside of the chamber facing the interior cools to below 0 0 C, cooled water in the chamber rises so long, rather than to freeze until the entire chamber contents 0 0 C has cooled. If, however, the bottom of the chamber is warmer than 4 ° C, forms a inside the chamber
Temperaturschichtung des Wassers aus, so dass das Wasser in der Kammer zur thermischen Isolation des Innenraums beiträgt.Temperature stratification of the water, so that the water in the chamber contributes to the thermal insulation of the interior.
Die Kammer kann in aus DE 10 2005 057 137 A1 bekannter Weise ein Wasserfilter enthalten, oder sie kann einfach als Wassertank vorgesehen sein.The chamber can contain a water filter in a manner known from DE 10 2005 057 137 A1, or it can simply be provided as a water tank.
Um ein Gefrieren des Inhalts der Kammer sicher auszuschließen, kann der Kammer eine elektrische Heizeinrichtung zugeordnet sein.To safely exclude freezing of the contents of the chamber, the chamber may be associated with an electric heater.
Bei einem Kältegerät, das sowohl einen Tank als auch ein Wasserfilter umfasst, ist eine gute Platzausnutzung erreichbar, wenn beide in einer gleichen Wand untergebracht sind.In a refrigeration device, which includes both a tank and a water filter, good space utilization can be achieved if both are housed in a same wall.

Fig. 1 zeigt einen schematischen Schnitt in Tiefenrichtung durch ein Kältegerät gemäß einer ersten Ausgestaltung der Erfindung. Ein Korpus 1 und eine am Korpus 1 angelenkte Tür 2 sind in dem Fachmann vertrauter Weise hergestellt, indem ein Zwischenraum zwischen einer aus Kunststoff einstückig tiefgezogenen Innenwand und einer aus einem oder mehreren gebogenen Blechen zusammengefügten Außenwand mit einem festen Isolierschaum 4 ausgefüllt ist. Der Isolierschaum 4 erstreckt sich bis in eine in einen Sockelbereich 5 des Korpus vorspringende Tasche 6, in der eine zur Vorderseite des Korpus 1 hin offene Aussparung 7 gebildet ist. In der Aussparung 7 ist eine Filterkartusche 8 untergebracht. An die Filterkartusche 8 ist ein wärmeisolierender Deckel 9 angefügt, der die Aussparung 7 zur Vorderseite des Geräts hin dicht abschließt. Die Aussparung 7 ist somit sowohl gegen die Umgebung als auch gegen den Innenraum 3 thermisch isoliert, wobei aber die Dicke der Isolierschicht zwischen der Aussparung 7 und dem Innenraum 3 geringer ist als zum Beispiel an Seiten- oder Rückwand des Korpus 1. Eine Wasserleitung 10 verläuft von einem nicht dargestellten, außerhalb des Geräts liegenden Versorgungsanschluss zur Filterkartusche 8 und von dieser innerhalb des Isolierschaums 4 zu einem an einer Rückwand 11 des Korpus 1 montierten Eisbereiter 12 sowie zu einer Zapfstelle 13 für gekühltes Wasser, die in einer Nische 14 an der Vorderseite der Tür 2 angebracht ist.Fig. 1 shows a schematic section in the depth direction by a refrigerator according to a first embodiment of the invention. A carcass 1 and a door 2 hinged to the carcass 1 are made in a familiar manner to the person skilled in the art by filling a gap between an inner wall integrally molded of plastics material and an outer wall joined together by one or more bent plates and filled with a solid insulating foam 4. The insulating foam 4 extends into a projecting into a base region 5 of the body pocket 6, in which an open towards the front of the body 1 recess 7 is formed. In the recess 7, a filter cartridge 8 is housed. To the filter cartridge 8, a heat-insulating cover 9 is added, which closes the recess 7 to the front of the device towards tight. The recess 7 is thus thermally insulated both against the environment and against the interior 3, but the thickness of the insulating layer between the recess 7 and The interior space 3 is smaller than, for example, on the side or rear wall of the body 1. A water line 10 extends from a supply connection, not shown, outside the device to the filter cartridge 8 and from there within the insulating foam 4 to one on a rear wall 11 of the body 1 mounted icemaker 12 and to a tapping point 13 for chilled water, which is mounted in a niche 14 at the front of the door 2.
Durch geeignete Wahl der Schichtdicken des Isolierschaums 4 zwischen dem Innenraum 3 und der Aussparung 7 bzw. zwischen der Aussparung 7 und der Umgebung kann eine Temperatur von wenig über 00C in der Aussparung 7 auch dann eingestellt werden, wenn der Innenraum 3 selbst auf einer Temperatur unter 00C gehalten ist.By a suitable choice of the layer thicknesses of the insulating foam 4 between the interior 3 and the recess 7 and between the recess 7 and the environment, a temperature of a little above 0 0 C in the recess 7 can be adjusted even if the interior 3 itself on a Temperature is kept below 0 0 C.
Um ein Einfrieren der Kartusche auch bei ungewöhnlich niedrigen Umgebungstemperaturen zu verhindern, kann in der Aussparung 7 ein Temperaturfühler 15 und eine durch diesen gesteuerte elektrische Heizung 16 vorgesehen sein, die immer dann in Betrieb geht, wenn die Temperatur in der Aussparung 7 der 0°-Grenze kritisch nahe kommt.In order to prevent freezing of the cartridge even at unusually low ambient temperatures, a temperature sensor 15 and a controlled by this electric heater 16 may be provided in the recess 7, which always goes into operation when the temperature in the recess 7 of 0 ° Border comes critically close.
In der Filterkartusche 8 gekühltes Wasser kann unmittelbar dem Eisbereiter 12 oder der Zapfstelle 13 zugeführt werden. Insbesondere zur Deckung des Bedarfs des Eisbereiters 12 ist der Inhalt der Kartusche 8 in der Regel ausreichend. Um an der Zapfstelle 13 auch größere Mengen kalten Wassers abzapfen zu können, als dem Fassungsvermögen der Filterkartusche 8 entspricht, ist diese über die Wasserleitung 10 vorzugsweise noch mit einem Wassertank 17 in Reihe verbunden, der, wie in dem Schnitt der Fig. 2 zu sehen, ebenfalls in den Isolierschaum 4 der Tasche 6 eingebettet ist.In the filter cartridge 8 cooled water can be supplied directly to the ice maker 12 or the tapping point 13. In particular, to meet the needs of the ice maker 12, the contents of the cartridge 8 is usually sufficient. In order to tap at the tapping point 13 and larger amounts of cold water than the capacity of the filter cartridge 8 corresponds, this is preferably still connected via the water pipe 10 with a water tank 17 in series, as seen in the section of FIG , is also embedded in the insulating foam 4 of the bag 6.
Fig. 3 zeigt eine abgewandelte Ausgestaltung, bei der die thermische Isolation zwischen dem Innenraum 3 und der Filterkartusche 8 und, sofern vorhanden, einem Wassertank durch einen mit Isolationsmaterial ausgefüllten, in den Boden des Innenraums 3 eingefügten Deckel 18 gebildet ist. Um die Filterkartusche 8 leicht austauschen zu können, kann eine Fassung 19, die in die Filterkartusche 8 eingeschraubt ist, mit anderen Teilen der Wasserleitung 10 flexibel, zum Beispiel über Schlauchabschnitte, verbunden sein. Falls ein Benutzer keine Filterung des Trinkwassers benötigt, kann die Filterkartusche 8 in allen Ausgestaltungen der Erfindung auch durch eine Leerkartusche ersetzbar sein, die keine Filterwirkung aufweist und lediglich einen Wassertank bildet.3 shows a modified embodiment in which the thermal insulation between the interior 3 and the filter cartridge 8 and, if present, a water tank is formed by a lid 18 filled with insulation material and inserted into the bottom of the interior 3. In order to easily replace the filter cartridge 8, a socket 19, which is screwed into the filter cartridge 8, with other parts of the water pipe 10 flexibly, for example via hose sections, be connected. If a user does not require filtering of the drinking water, the filter cartridge 8 may be replaceable in all embodiments of the invention by an empty cartridge, which has no filtering effect and forms only a water tank.
Fig. 4 zeigt eine Ausgestaltung, bei der die Filterkartusche 8 und der Wassertank 17 in die Decke 20 des Korpus verlagert sind. Um eine gute Platzausnutzung zu erreichen undFig. 4 shows an embodiment in which the filter cartridge 8 and the water tank 17 are displaced into the ceiling 20 of the body. To achieve a good space utilization and
Stufen an der Unterseite der Decke 20 zu vermeiden, sind die Filterkartusche 8 und derTo avoid steps on the underside of the ceiling 20, the filter cartridge 8 and the
Wassertank 17 hier flach quaderförmig ausgeführt. Da Filter 8 und Tank 17 bei dieserWater tank 17 here flat cuboid running. Since filter 8 and tank 17 at this
Ausgestaltung von unten gekühlt sind, kann ihr gesamter Inhalt bis auf 00C abkühlen, bevor es zur Eisbildung darin kommt. Diese Anordnung ist daher relativ tolerant gegen eine Unterkühlung.Cooled configuration from below, can cool their entire content to 0 0 C before it comes to ice formation in it. This arrangement is therefore relatively tolerant of hypothermia.
Fig. 5 zeigt in einem zu Fig. 2 analogen Schnitt eine Ausgestaltung mit einem in der Decke 20 des Korpus 1 benachbart zur Filterkartusche 8 und Wassertank 17 angeordneten Verdampfer 21. Obwohl Tank und Filter ihre Wärme an den Innenraum über eine im Vergleich zur Ausgestaltung der Fig. 4 relative kleine Oberfläche an den Innenraum 3, nämlich im Wesentlichen nur über den Deckel 18 abgeben, ist eine unerwünschte Erwärmung von Kühlgut dadurch kaum zu befürchten, da dieses die Decke 20 nur selten unmittelbar berührt. Durch eine Anbringung des Eisbereiters 12 unterhalb des die Nische des Tanks 17 und der Filterkartusche 8 verschließenden Deckels 18 kann ein Kontakt des relativ warmen Deckels 18 mit Kühlgut vollständig ausgeschlossen werden.Fig. 5 shows in an analogous to FIG. 2 section of an embodiment with a in the ceiling 20 of the body 1 adjacent to the filter cartridge 8 and water tank 17 arranged evaporator 21. Although tank and filter their heat to the interior via a compared to the embodiment of Fig. 4 Relatively small surface to the interior 3, namely substantially only give over the lid 18, an undesirable heating of refrigerated goods is thus hardly to be feared, since this rarely touches the ceiling 20 directly. By attaching the ice maker 12 below the niche of the tank 17 and the filter cartridge 8 occlusive lid 18, a contact of the relatively warm lid 18 can be completely excluded with refrigerated goods.
Fig. 6 zeigt eine Ausgestaltung, bei der die Filterkartusche 8 und der Wassertank 17 in einer Seitenwand 22 des Korpus 1 untergebracht sind, wobei eine die Filterkartusche 8 aufnehmende Nische vom Innenraum durch den Deckel 18 abgeteilt ist. Eine entsprechende Anbringung von Filter und/oder Tank an der Rückwand des Korpus 1 kommt ebenfalls in Betracht, sofern diese nicht von einem Verdampfer belegt ist.Fig. 6 shows an embodiment in which the filter cartridge 8 and the water tank 17 are accommodated in a side wall 22 of the body 1, wherein a filter cartridge 8 receiving niche is partitioned from the interior through the lid 18. An appropriate attachment of filter and / or tank on the rear wall of the body 1 is also considered, unless it is occupied by an evaporator.
Fig. 7 zeigt einen Schnitt durch ein Kombinationskältegerät mit einem Gefrierfach 23 und einem Normalkühlfach 24, bei dem eine austauschbare Filterkartusche 8 und ein Wassertank 17 in einer horizontalen Trennwand 25 zwischen den Fächern 23, 24 untergebracht sind.
