Description

Kältegerät mit Kaltwasserspender Refrigerating appliance with cold water dispenser
Haushaltskältegeräte mit einem eingebauten, gekühlten Wassertank, aus dem an einem Spender an der Geräteaußenseite Wasser abzapfbar ist, ohne das Gerät öffnen zu müssen, erfreuen sich bei den Verbrauchern zunehmender Beliebtheit. Um das Wasser im Tank auf einer Temperatur halten zu können, die von der Temperatur eines Innenraums des Kältegeräts verschieden ist, ist der Tank häufig in eine Isolationsmaterialfüllung eingelassen, mit der ein Zwischenraum zwischen einer festen Innen- und Außenhaut der Wand ausgefüllt ist. Eine Isolation des Tanks sowohl gegenüber dem Innenraum als auch der Umgebung ist insbesondere dann erforderlich, wenn der Innenraum Temperaturen unter 00C annehmen kann.Domestic refrigeration appliances with a built-in, cooled water tank, from which water can be tapped off at a dispenser on the outside of the device, without having to open the device, are becoming increasingly popular with consumers. In order to keep the water in the tank at a temperature that is different from the temperature of an interior of the refrigerator, the tank is often embedded in an insulating material filling with which a gap between a solid inner and outer skin of the wall is filled. An insulation of the tank both with respect to the interior and the environment is particularly necessary if the interior can assume temperatures below 0 0 C.
Die Einbettung des Tanks in das Isoliermaterial macht es erforderlich, dass Zu- und Ableitungen des Tanks sich durch die Isolationsmaterialfüllung erstrecken. Stellen, an denen die Zu- und Ableitungen Innen- oder Außenwand der Haut kreuzen, müssen sorgfältig abgedichtet sein, um zu verhindern, dass feuchte Luft in die Isolationsmaterialfüllung eindringen und ihre Feuchtigkeit in der Füllung auskondensieren kann. Wenn die Isolationsmaterialfüllung in üblicherweise aus einem in den Zwischenraum eingespritzten und daran zu einem Schaum expandierten Kunstharz besteht, ist eine sorgfältige Abdichtung auch erforderlich, um einen Austritt von expandierendem Harz zu verhindern. Die Leitungsdurchführungen tragen daher erheblich zu den Fertigungskosten eines solchen Kältegeräts bei. Wenn an den Zapfstellen elektrische Verbraucher, Signalgeber, Schalter, etc vorgesehen sind, ergeben sich entsprechende Probleme bei der Verlegung von deren Anschlusskabeln.The embedding of the tank in the insulating material requires that the supply and discharge lines of the tank extend through the insulating material filling. Where the inlets and outlets cross the inner or outer wall of the skin, they must be carefully sealed to prevent moist air from entering the insulation material filling and allowing its moisture to condense in the filling. If the insulative material fill is typically a resin injected into the gap and expanded into a foam, careful sealing is also required to prevent leakage of expanding resin. The cable bushings therefore contribute significantly to the manufacturing cost of such a refrigerator. If electrical consumers, signalers, switches, etc are provided at the taps, corresponding problems arise when laying their connecting cables.
Ein weiteres Problem ist, dass Teile, die mit Isolationsmaterial in Form von expandiertem Kunstharz in Kontakt sind, im Falle eines Defekts kaum sinnvoll ausgetauscht und repariert werden können. Wenn, wie vielfach der Fall, die Zapfstelle an einer Tür des Kältegeräts angeordnet ist, kann im Fall eines solchen Defekts meist nur die gesamte Tür ausgetauscht werden, was für den Benutzer des Geräts mit erheblichen Kosten verbunden ist. Aufgabe der vorliegenden Erfindung ist daher, ein Kältegerät mit Kaltwasserspender zu schaffen, das einfach und preiswert montierbar und reparaturfreundlich ist.Another problem is that parts that are in contact with insulation material in the form of expanded resin in the event of a defect can hardly be meaningfully replaced and repaired. If, as is often the case, the tapping point is arranged on a door of the refrigerator, in the case of such a defect usually only the entire door can be replaced, which is associated with considerable costs for the user of the device. Object of the present invention is therefore to provide a refrigerator with cold water dispenser, which is easy and inexpensive to install and easy to repair.
Diese Aufgabe wird bei einem Kältegerät mit einem Gehäuse, bei dem in einer Wand des Gehäuses eine nach außen offene, eine Zapfstelle für gekühltes Wasser oder dergleichen enthaltende Nische gebildet ist, und wobei die Wand eine einen Innenraum begrenzende Innenhaut, eine Außenhaut und eine sich zwischen Innen- und Außenhaut erstreckende Isolationsmaterialfüllung umfasst, und mit einem Vorratsbehälter für an der Zapfstelle abzuzapfendes Wasser oder dergleichen dadurch gelöst, dass in die Nische eine isolierende Zwischenwand eingefügt ist, die einen den Vorratsbehälter aufnehmenden inneren Bereich der Nische von einem die Zapfstelle aufnehmenden äußeren Bereich trennt. Durch Platzieren des Vorratsbehälters in der Nische wird die Notwendigkeit vermieden, diesen zur Schutz vor Unterkühlung in das Isolationsmaterial einzubetten, während eine ausreichende Kühlbarkeit des Vorratsbehälters dadurch sicher gestellt ist, dass er von der Umgebung durch die isolierende Zwischenwand abgeschirmt ist. Durch Abmontieren der Zwischenwand kann der Vorratsbehälter freigelegt werden, so dass Reparaturen an ihm möglich sind.This object is achieved in a refrigerator with a housing in which in a wall of the housing an outwardly open, a tapping point for chilled water or the like containing niche is formed, and wherein the wall defining an inner skin, an outer skin and a between Inner and outer skin extending insulating material filling comprises, and with a reservoir for tapped at the tapping point water or the like solved in that in the niche an insulating partition is inserted, which separates the reservoir receiving the inner region of the niche of the tapping receiving outer region , By placing the reservoir in the niche, the need to embed it in the insulation material for protection against hypothermia is avoided, while adequate cooling of the reservoir is ensured by being shielded from the environment by the insulating partition. By dismantling the partition, the reservoir can be exposed so that repairs to it are possible.
Eine erhebliche Vereinfachung des Zusammenbaus ergibt sich, wenn eine den Vorratsbehälter versorgende Wasserleitung in einem in die Außenhaut der Wand eingetieften Kanal aufgenommen ist. Dadurch entfällt die Notwendigkeit, die Versorgungsleitung des Vorratsbehälters durch die Isolationsmaterialführung hindurchzuführen, und eine aufwendige Abdichtung von Durchbrüchen in Innen- und Außenhaut der Wand ist nicht erforderlich.A considerable simplification of the assembly results when a reservoir supplying the water pipe is accommodated in a recessed into the outer skin of the wall channel. This eliminates the need to pass the supply line of the reservoir through the insulation material guide, and a complex sealing of openings in the inner and outer skin of the wall is not required.
Ein solcher in die Außenhaut der Wand eingetiefter Kanal kann ferner auch eine Versorgungsleitung für einen an der Nische angeordneten elektrischen Verbraucher aufnehmen.Such a channel, which is countersunk into the outer skin of the wall, can furthermore also receive a supply line for an electrical consumer arranged at the niche.
Ein Durchgang in der Wand, der den inneren Bereich der Nische mit dem Innenraum verbindet, ermöglicht eine effiziente und schnelle Kühlung des Vorratsbehälters durch Luftaustausch zwischen dem inneren Bereich der Nische und dem Innenraum. Um den Luftaustausch zu fördern, kann an dem wenigstens einem Durchgang ein Ventilator angebracht sein. Dieser kann einen elektrischen Verbraucher wie oben erwähnt darstellen.A passage in the wall, which connects the inner region of the niche with the interior, allows efficient and rapid cooling of the reservoir by air exchange between the inner region of the niche and the interior. In order to promote the exchange of air, a fan may be attached to the at least one passage. This can represent an electrical consumer as mentioned above.
Eine zum Vorratsbehälter benachbarte Heizung kann als ein Schutz vor dem Gefrieren des Tankinhalts vorgesehen werden. Auch sie kann einen elektrischen Verbraucher darstellen.A heater adjacent to the reservoir may be provided as protection against freezing of the tank contents. It too can be an electrical consumer.
Um eine effiziente Wärmeübertragung von der Heizung auf den Tankinhalt bei geringem Wärmetransfer an den Innenraum zu gewährleisten, ist die Heizung zweckmäßigerweise an einer der isolierenden Zwischenwand zugewandten Seite des Tanks angeordnet.In order to ensure efficient heat transfer from the heater to the tank contents with low heat transfer to the interior, the heater is expediently arranged on one of the insulating intermediate wall facing side of the tank.
Um an der Zapfstelle auch die Entnahme von Eis zu ermöglichen, ist vorzugsweise in dem Innenraum des Kältegeräts ein Eisvorratsbehälter angeordnet, den ein Durchgang der Wand mit dem äußeren Bereich der Nische verbindet.In order to enable the removal of ice at the tapping point, an ice storage container is preferably arranged in the interior of the refrigerator, which connects a passage of the wall with the outer region of the niche.
Der Durchgang ist zweckmäßigerweise durch eine elektrisch steuerbare Klappe verschließbar, so dass, wenn kein Eis entnommen wird, keine warme Außenluft durch den Durchgang in den Innenraum gelangt.The passage is suitably closed by an electrically controllable flap, so that when no ice is removed, no warm outside air passes through the passage in the interior.
Die Klappe ist zweckmäßigerweise Teil einer in die Nische eingefügten Baugruppe. So ist die Baugruppe durch die Außenhaut der Wand von dem Isolationsmaterial getrennt und kann daher, wenn eine Reparatur erforderlich ist, entfernt werden, ohne das Isolationsmaterial in Mitleidenschaft zu ziehen.The flap is expediently part of an assembly inserted into the niche. Thus, the assembly is separated from the insulation material by the outer skin of the wall and therefore, if repair is required, can be removed without affecting the insulation material.
Um Taubildung in dem nach außen freiliegenden äußeren Bereich der Nische zu verhindern, kann an einer dem äußeren Bereich der Nische zugewandten Oberfläche der isolierenden Wand eine Heizung vorgesehen sein.In order to prevent dew formation in the externally exposed outer region of the niche, heating may be provided on a surface of the insulating wall facing the outer region of the niche.

Das in Fig. 1 in einem schematischen Schnitt gezeigte Kältegerät hat einen wärmeisolierenden Korpus 1 und eine Tür 2, die einen Innenraum 3 begrenzen. Der Innenraum 3 ist durch einen Verdampfer gekühlt, der in einer im oberen Bereich des Korpus 1 abgeteilten Verdampferkammer 4 untergebracht ist.The refrigerating appliance shown in a schematic section in FIG. 1 has a heat-insulating body 1 and a door 2 which delimit an interior space 3. The interior space 3 is cooled by an evaporator which is accommodated in an evaporator chamber 4 divided off in the upper region of the body 1.
Ein automatischer Eisbereiter 5 ist in unmittelbarer Nachbarschaft der Verdampferkammer 4 im Innenraum 3 angeordnet. Unter dem Eisbereiter 5 ist ein Sammelbehälter 6 angebracht, der von dem Eisbereiter 5 erzeugte Eisstücke auffängt. Eine Förderschnecke 7 am Boden des Sammelbehälters 6 dient zum Fördern der Eisstücke zu einer Ausgabeöffnung 8 am türnahen Ende des Sammelbehälters 6.An automatic ice maker 5 is arranged in the immediate vicinity of the evaporator chamber 4 in the interior 3. Under the icemaker 5, a collecting container 6 is mounted, which catches ice pieces 5 produced by the ice maker. A screw conveyor 7 at the bottom of the collecting container 6 serves to convey the pieces of ice to a discharge opening 8 at the door near the end of the collecting container. 6
Die Wände von Korpus 1 und Tür 2 des Kältegeräts sind in an sich bekannter Weise jeweils durch eine feste Außenhaut , eine feste Innenhaut 9 und eine zwischen beiden eingeschlossene Isoliermaterialschicht 10 aus Schaumstoff gebildet. Die hier mit einer Möbelplatte 11 verblendet dargestellte Außenhaut der Tür 2 ist im Wesentlichen aus zwei Teilen zusammengefügt, einer im wesentlichen ebenen Frontplatte 12 und einem in eine zentrale Öffnung der Frontplatte 12 eingefügten, eine zur Außenseite der Tür 2 hin offene Nische 13 begrenzenden Kunststoffgehäuse 14. In der Innenhaut 9 der Tür ist eine zu dem Gehäuse 14 komplementäre Ausbuchtung 15 geformt. An einer Oberseite dieser Ausbuchtung 15 ist unterhalb der Ausgabeöffnung 8 des Sammelbehälters 6 ein Schacht oder Trichter 16 geformt, von dem ein unterer Rand dicht an das Gehäuse 14 anschließt, so dass aus dem Sammelbehälter 6 ausgegebenes Eis durch den Schacht 16 in die Nische 13 gelangt. Die Nische 13 ist durch eine eingefügte isolierende Zwischenwand 17 in einen inneren Bereich 18 und einen äußeren Bereich 19 gegliedert. Der innere Bereich 18 ist durch einen im vorliegenden Fall als Wassertank 20 ausgebildeten Vorratsbehälter im Wesentlichen ausgefüllt. Der Wassertank 20 ist durch eine Versorgungsleitung 21 an das Trinkwassernetz angeschlossen.The walls of the body 1 and door 2 of the refrigerator are formed in a conventional manner in each case by a solid outer skin, a solid inner skin 9 and an enclosed between the two insulating material layer 10 of foam. The outer skin of the door 2 shown here with a furniture panel 11 is essentially composed of two parts, a substantially flat front panel 12 and a plastic housing 14 delimiting a niche 13 open to the outside of the door 2 and inserted in a central opening of the front panel 12 In the inner skin 9 of the door, a recess 15 complementary to the housing 14 is formed. At a top of this bulge 15, a shaft or funnel 16 is formed below the discharge opening 8 of the collecting container 6, of which a lower edge connects tightly to the housing 14, so that out of the collecting container 6 ice passes through the shaft 16 into the niche 13 , The niche 13 is divided by an inserted insulating partition 17 into an inner region 18 and an outer region 19. The inner region 18 is substantially filled by a reservoir formed in the present case as a water tank 20. The water tank 20 is connected by a supply line 21 to the drinking water network.
Die Versorgungsleitung 21 verläuft von einem nicht gezeigten externen Anschluss aus zunächst durch den Korpus 1 , wo an der Leitung 21 ein Sperrventil 22 angeordnet ist, das, solange kein Wasser aus dem Tank 20 abgezapft wird, geschlossen ist und so den stromabwärts von ihm liegenden Teil der Versorgungsleitung 21 und den Tank 20 von einem im Trinkwassernetz herrschenden Überdruck abschirmt. Die Versorgungsleitung 21 ist aus dem Korpus 1 benachbart zu einem Scharnier der Tür 2 herausgeführt und tritt in einen in Fig. 2 gezeigten, sich entlang eines unteren Randes der Tür 2 erstreckenden rillenförmigen Kanal 23 über.The supply line 21 extends from an external connection, not shown, first through the body 1, where on the line 21, a check valve 22 is arranged, which, as long as no water is tapped from the tank 20, is closed and so the downstream of him lying part the supply line 21 and the tank 20 shields from a pressure prevailing in the drinking water network overpressure. The supply line 21 is led out of the body 1 adjacent to a hinge of the door 2 and enters a groove-shaped channel 23, shown in FIG. 2, extending along a lower edge of the door 2.
In Fig. 2 ist ein zweischenkliger Kanal 23 gezeigt, wobei jeweils ein Schenkel des Kanals von einer der zwei unteren Ecken der Tür 2 zu einem an der Vorderseite der Tür gebildeten Ausschnitt 24 verläuft. So kann die Tür der Fig. 2 wahlweise rechts oder links angeschlagen werden, wobei je nach Anschlagseite der Türscharniere die Versorgungsleitung 21 durch einen der zwei Schenkel des Kanals 23 geführt wird. Wenn keine Wahlmöglichkeit für die Anschlagseite der Tür 2 vorgesehen ist, genügt es, wenn der Kanal 23 einen einzigen Schenkel aufweist.In Fig. 2 a zweischkliger channel 23 is shown, wherein in each case a leg of the channel extends from one of the two lower corners of the door 2 to a cutout 24 formed at the front of the door. Thus, the door of Fig. 2 can be struck either right or left, depending on the stop side of the door hinges, the supply line 21 is guided through one of the two legs of the channel 23. If no option for the stop side of the door 2 is provided, it is sufficient if the channel 23 has a single leg.
An dem Ausschnitt 24 beginnt, wie in der perspektivischen Ansicht der Fig. 3 zu erkennen, ein in die Außenhaut 9 eingetiefter, sich vertikal bis zu der Nische 13 erstreckender Kanal 25. Der Kanal 25 geht über in einen Kanal 26, der sich am Boden des Gehäuses 14 in Tiefenrichtung bis kurz hinter eine Stufe 27 erstreckt. DieAt the cutout 24 begins, as can be seen in the perspective view of Fig. 3, a eingetiefter in the outer skin 9, vertically extending to the niche 13 channel 25. The channel 25 merges into a channel 26, located at the bottom of the housing 14 in the depth direction to just after a step 27 extends. The
Versorgungsleitung 21 ist im hier dargestellten Fall in dem Kanal 25 von derSupply line 21 is in the case shown here in the channel 25 of the
Möbelplatte11 verdeckt; es kann aber auch zur Sicherung der Versorgungsleitung 21 in dem Kanal 25 ein (nicht dargestelltes) U-Profil über die Versorgungsleitung 21 gestülpt und an den Seiten des Kanals 25 befestigt, z.B. verrastet, sein. Auf gleicher Tiefe wie die Stufe 27 ist an der Decke des Gehäuses 14 eine zweite, in Fig. 3 gestrichelt dargestellte Stufe 28 gebildet.Furniture panel11 concealed; but it can also be used to secure the supply line 21 in the channel 25 a (not shown) U-profile placed over the supply line 21 and attached to the sides of the channel 25, for example, locked. At the same depth as the step 27, a second step 28 shown in dashed lines in FIG. 3 is formed on the ceiling of the housing 14.
In einer rückwärtigen unteren Ecke des Gehäuses 14 sind zwei Durchgänge 29, 30 zu sehen, die sich durch die Tür 2 hindurch in den Innenraum 3 erstrecken. Während der Durchgang 29 frei ist, ist der nur teilweise sichtbare Durchgang 30 mit einem Ventilator versehen.In a rear lower corner of the housing 14, two passages 29, 30 can be seen, which extend through the door 2 into the interior 3. While the passage 29 is free, the only partially visible passage 30 is provided with a fan.
Der hinter den Stufen 27, 28 liegende innere Bereich 18 der Nische 13 ist vorgesehen, um den Wassertank 20 aufzunehmen. Dieser ist in Fig. 3 zusammen mit seiner Versorgungsleitung 21 gezeigt, die entsprechend dem Verlauf der sie aufnehmenden Kanäle 23, 25, 26 gekrümmt dargestellt ist.The inner region 18 of the niche 13 located behind the steps 27, 28 is provided to receive the water tank 20. This is shown in Fig. 3 together with its supply line 21, which is shown curved according to the course of the female receiving channels 23, 25, 26.
Wenn der Wassertank 20 eingebaut ist, verbleibt zwischen dessen Rückwand und der Rückwand des Gehäuses 14 ein Spalt, in welchem, angetrieben durch den Ventilator im Durchgang 30, Kaltluft aus dem Innenraum 3 zirkulieren kann, um den Inhalt des Tanks schnell zu kühlen.When the water tank 20 is installed, a gap remains between the rear wall thereof and the rear wall of the housing 14, in which, driven by the fan in the passage 30, cold air can circulate out of the inner space 3 to quickly cool the contents of the tank.
Ein an einem oberen Bereich des Tanks 20 angeordneter Temperaturfühler 31 steuert den Betrieb des Ventilators sowie einer an der vorderen Wand des Tanks 20 angebrachten Folienheizung 32. Wenn die vom Temperaturfühler 31 erfasste Wassertemperatur einen ersten Grenzwert überschreitet, wird zum Kühlen des Tankinhalts der Ventilator aktiviert, unterschreitet die Temperatur einen zweiten, niedrigeren Grenzwert, wird die Folienheizung 32 in Betrieb genommen um ein Einfrieren des Tankinhalts zu verhindern.A temperature sensor 31 disposed at an upper portion of the tank 20 controls the operation of the fan and a film heater 32 mounted on the front wall of the tank 20. When the water temperature detected by the temperature sensor 31 exceeds a first threshold, the fan is activated to cool the tank contents, If the temperature falls below a second, lower limit, the film heater 32 is put into operation to prevent freezing of the tank contents.
Im zusammengebauten Zustand ist der Wassertank 20 hinter der isolierenden Zwischenwand 17 verborgen. Die Position der Zwischenwand 17 ist dadurch festgelegt, dass ihre Rückseite an die zwei Stufen 27, 28 anschlägt. Durch einen Ausschnitt 33 an der oberen Kante der Zwischenwand 17 ist eine Ausgabeleitung 34 des Tanks 20 zu einer Spenderbaugruppe 35 in dem äußeren Bereich 19 herausgeführt. Diese Spenderbaugruppe 35 ist vorgesehen, um in der Nische 13 unter dem Dach des Gehäuses 14 montiert zu werden, und ist in Fig. 4 in einem Schnitt gezeigt. Ein Durchgang 36 der Baugruppe 35 verlängert den Schacht 16 und ist durch eine an einer Achse 37 schwenkbar aufgehängte Klappe 38 verschlossen. Die Ausgabeleitung 34 ist in der Spenderbaugruppe 35 durch einen flexiblen Schlauch 39 verlängert, der auf einen an der Außenseite der Klappe 38 montierten Ausgabestutzen 40 mündet. Wenn die Klappe 38 geöffnet wird, um Eis zu entnehmen, wird der Ausgabestutzen 40 beiseite geschwenkt. Ein Behälter kann daher zum Auffangen der Eisstücke bzw. zum Abzapfen von Wasser an der gleichen Stelle in der Nische 13 positioniert werden.In the assembled state, the water tank 20 is hidden behind the insulating partition 17. The position of the intermediate wall 17 is determined by its rear abutting the two steps 27, 28. Through a cutout 33 on the upper edge of the intermediate wall 17, an output line 34 of the tank 20 is led out to a dispenser assembly 35 in the outer region 19. This dispenser assembly 35 is intended to be mounted in the niche 13 under the roof of the housing 14, and is shown in Fig. 4 in a section. A passage 36 of the assembly 35 extends the shaft 16 and is connected by a to a Axis 37 pivotally hinged flap 38 closed. The dispensing line 34 is extended in the dispenser assembly 35 by a flexible hose 39 which opens onto a dispensing nozzle 40 mounted on the outside of the flap 38. When the flap 38 is opened to remove ice, the discharge port 40 is pivoted aside. A container can therefore be positioned at the same location in the niche 13 for catching the pieces of ice or for tapping water.
Eine so genannte Pitcherklappe 41 ist zur Montage am Boden des Gehäuses 14 vorgesehen. Es handelt sich um eine Baugruppe von in etwa kastenartiger Gestalt, wobei von den Wänden des Kastens eine vordere Wand und eine obere Wand 42 in in Fig. 3 gezeigter Weise ausklappbar sind. In eingeklappter Stellung kann ein kleiner Behälter auf die Außenseite der oberen Wand 42 gestellt werden, um Wasser oder Eis aufzufangen; in aufgeklappter Stellung kann ein mittelgroßer Behälter auf einer Bodenfläche 43 der Pitcherklappenbaugruppe 40 platziert werden, oder ein großer Behälter kann auf der Innenseite der oberen Wand 42 schräg gestellt werden, so dass seine Einfüllöffnung unter dem Ausgabestutzen 39 bzw. der Klappe 38 zu liegen kommt.A so-called pitch flap 41 is provided for mounting at the bottom of the housing 14. It is an assembly of approximately box-like shape, wherein from the walls of the box, a front wall and an upper wall 42 in the manner shown in Fig. 3 are foldable. In the folded position, a small container can be placed on the outside of the top wall 42 to catch water or ice; In the unfolded position, a medium-sized container may be placed on a bottom surface 43 of the pitcher flap assembly 40, or a large container may be slanted on the inside of the top wall 42 so that its fill opening is below the dispensing spout 39 and flap 38, respectively.
Eine Steuerungsbaugruppe 44, die an der Vorderseite des Geräts freiliegende Schalter 45 trägt, ist unter der Decke des Gehäuses 14 die Spenderbaugruppe 35 nach vorn verdeckend montiert. Die Schalter 45 dienen zur Steuerung des Betriebs der Klappe 38, der Förderschnecke 7, des Sperrventils 22, etc. Signalleitungen, die zur Steuerung des Sperrventils 22 und der Förderschnecke 8 die Steuerungsbaugruppe 44 mit dem Korpus 1 verbinden, verlaufen zusammen mit der Versorgungsleitung 21 entlang der Kanäle 26, 25, 23. Des weiteren verläuft durch diese Kanäle 26, 25, 23 ein elektrisches Versorgungskabel zur Versorgung von diversen in der Nische 13 montierten elektrischen Verbrauchern wie etwa der Folienheizung 32 des Wassertanks, einer an der Außenseite der Zwischenwand 17 angebrachten Folienheizung 47, die zum Verhindern von Taubildung an der Zwischenwand 17 dient, einer (nicht dargestellten) Beleuchtung, die z. B. in die Spenderbaugruppe 35 integriert sein kann, um einen zu befüllenden Behälter zu in der Nische 13 beleuchten, des Ventilators im Durchgang 30 oder einer in die Klappe 38 integrierten Heizung, die die Taubildung im Durchgang 36 der Spenderbaugruppe 35 sowie gegebenenfalls ein Festfrieren der Klappe 38 in der den Durchgang 36 versperrenden Stellung verhindert. Entsprechend der Reihenfolge ihrer Anordnung in Fig. 3 sind der Tank 20 mit seinen angeschlossenen Leitungen 21 , 34, die Zwischenwand 17 und die Baugruppen 35, 41 , 44 an der fertig zusammengebauten und mit Isoliermaterial ausgeschäumten Tür 2 montierbar und können im Bedarfsfall jeweils wieder abmontiert werden, um repariert oder ausgetauscht zu werden. Für eine solche Reparatur ist es nicht einmal erforderlich, die Tür 2 zu öffnen, so dass keine Gefahr einer unerwünschten Erwärmung von im Innenraum 3 gelagerten Kühlgut durch die Reparatur besteht. A control assembly 44 carrying exposed switches 45 on the front of the device is mounted under the ceiling of the housing 14 to conceal the dispenser assembly 35. The switches 45 serve to control the operation of the flap 38, the auger 7, the check valve 22, etc. Signal lines connecting the control assembly 44 to the body 1 for controlling the check valve 22 and the auger 8 extend along with the supply line 21 of the channels 26, 25, 23. Furthermore, runs through these channels 26, 25, 23, an electrical supply cable for supplying various mounted in the niche 13 electrical loads such as the film heater 32 of the water tank, mounted on the outside of the intermediate wall 17 film heater 47, which serves to prevent dew formation on the intermediate wall 17, a (not shown) lighting, the z. B. may be integrated into the dispenser assembly 35 to illuminate a container to be filled in the niche 13, the fan in the passage 30 or integrated in the flap 38 heating, the dewing in the passage 36 of the dispenser assembly 35 and optionally a freezing of the Flap 38 in the passage 36 obstructing position prevents. According to the order of their arrangement in Fig. 3, the tank 20 with its connected lines 21, 34, the intermediate wall 17 and the assemblies 35, 41, 44 can be mounted on the finished assembled and foamed with insulating door 2 and can be removed again if necessary to be repaired or replaced. For such a repair, it is not even necessary to open the door 2, so that there is no risk of undesirable heating of refrigerated goods stored in the interior 3 by the repair.
