JP 2001 133129 A offenbart, dass ein Kompressor und ein wassergekühlte Kondensator auf den gegenüberliegenden Seiten des Gebläsemotors im Maschinenraumen angeordnet sind. JP 2001 133129 A discloses that a compressor and a water-cooled condenser are disposed on the opposite sides of the fan motor in the engine room.

EP 2 136 168 A1 offenbart eine Kühlvorrichtung mit einem Kühlsystem bestehend aus einem Kompressor und einem Kondensator, wobei eine Verdunstungsschale oberhalb des ersten Kondensatorteils des Kondensators angeordnet ist. EP 2 136 168 A1 discloses a cooling device with a cooling system consisting of a compressor and a condenser, wherein an evaporation tray is arranged above the first condenser part of the condenser.

Der vorliegenden Erfindung liegt die Aufgabe zugrunde, ein Kühl- und/oder Gefriergerät der eingangs genannten Art dahingehend weiterzubilden, dass auf einen derartigen Korrosionsschutz des Verflüssigers verzichtet werden kann und dennoch eine effiziente Wärmeübertragung vom Verflüssiger zur Verdunstungsschale bzw. zu dem darin befindlichen Kondenswasser möglich ist.
Diese Aufgabe wird durch ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 1 gelöst.
Danach ist vorgesehen, dass in oder an der Verdunstungsschale eine oder mehrere Aufnahmen für den oder die Verflüssiger vorgesehen sind, wobei die wenigstens eine Aufnahme derart angeordnet ist, dass das in der Verdunstungsschale befindliche Kondenswasser nicht mit dem Verflüssiger in Kontakt steht.
Die wenigstens eine Aufnahme für den wenigstens einen Verflüssiger ist somit derart angeordnet, dass der Verflüssiger nicht in dem Bereich angeordnet ist, der im Betrieb des Gerätes mit Kondenswasser gefüllt ist. Somit kann auf die genannte Korrosionsbeschichtung des Verflüssigers verzichtet werden, wodurch sich eine Kostenersparnis ergibt. Besonders vorteilhaft ist es, wenn die Aufnahme derart ausgeführt ist, dass die Abwärme des Verflüssigers zumindest teilweise durch die Aufnahme in das in der Verdunstungsschale befindliche Kondenswasser geleitet wird. Die Aufnahme ist somit vorzugsweise derart angeordnet, dass sie einerseits mit dem Verflüssiger in Verbindung steht und andererseits mit dem Kondenswasser in Verbindung steht, so dass die von dem Verflüssiger abgegebene Wärme durch die Aufnahme hindurch zumindest teilweise dem Kondenswasser zugeführt wird, wodurch dessen Verdunstung gefördert wird.The present invention has the object of developing a refrigerator and / or freezer of the type mentioned in that can be dispensed with such a corrosion protection of the condenser and yet efficient heat transfer from the condenser to the evaporation tray or to the condensate therein is possible ,
This object is achieved by a refrigerator and / or freezer with the features of claim 1.
Thereafter, it is provided that in or on the evaporation tray one or more receptacles for the condenser or are provided, wherein the at least one receptacle is arranged such that the condensate located in the evaporation tray is not in contact with the condenser.
The at least one receptacle for the at least one condenser is thus arranged such that the condenser is not arranged in the region which is filled with condensed water during operation of the device. Thus, can be dispensed with said corrosion coating of the condenser, resulting in a cost savings. It when the recording is carried out such that the waste heat of the condenser is at least partially passed through the inclusion in the condensation in the evaporation tray is particularly advantageous. The receptacle is thus preferably arranged in such a way that it communicates with the condenser on the one hand and with the condensed water on the other hand so that the heat released by the condenser is at least partially supplied to the condensed water through the receptacle, thereby promoting its evaporation ,

Die Verdunstungschale weist einen Boden auf, wobei die Aufnahme in Form eines oder mehrerer von dem Boden der Verdunstungsschale erstreckender Erhebungen bzw. Vorsprünge ausgeführt ist.The evaporation tray has a bottom, the receptacle being in the form of one or more elevations or projections extending from the bottom of the evaporation tray.

Weiterhin kann vorgesehen sein, dass die Aufnahme eine Wandung aufweist, die teilweise oder vollständig einen Hohlraum umgibt, in dem sich zumindest ein Abschnitt des Verflüssigers befindet. Ebenso ist es denkbar, dass die Aufnahme als kompakter Körper ausgeführt ist bzw. keinen Hohlraum aufweist, in den der Verflüssiger eingesetzt ist. Denkbar ist es, dass der Verflüssiger auf die Aufnahme aufgesetzt wird.
Die Wandung kann zum Zwecke einer optimalen Wärmeleitung vom Verflüssiger in das Kondenswasser aus einem besonders gut wärmeleitenden Material bestehen. Sie kann dünn ausgeführt werden, damit eine gute Wärmeleitung erfolgt.
Der Verflüssiger kann in dem genannten Hohlraum form- und/oder kraftschlüssig fixiert sein. Auch ist es möglich, den Verflüssiger kraft- und/oder formschlüssig in oder auf der Aufnahme zu fixieren.
In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der Hohlraum in seiner Kontur im Wesentlichen der Kontur des Verflüssigers entspricht. Denkbar ist es, dass die Aufnahme eine Wandung aufweist, die über eine oder mehrere Rippen verfügt, die derart angeordnet sind, dass die Rippen in den Bereich der Verdunstungsschale reichen, in dem sich im Betrieb des Gerätes das Kondenswasser befindet. Diese Rippen dienen somit zur Optimierung der Wärmeleitung vom Verflüssiger in den mit Kondenswasser gefüllten Bereich der Verdunstungsschale.Furthermore, it can be provided that the receptacle has a wall which partially or completely surrounds a cavity in which at least a portion of the condenser is located. It is also conceivable that the receptacle is designed as a compact body or has no cavity, in which the condenser is used. It is conceivable that the condenser is placed on the receptacle.
The wall may consist of a particularly good heat conducting material for the purpose of optimal heat conduction from the condenser in the condensate. It can be made thin, so that a good heat conduction takes place.
The condenser may be fixed positively and / or non-positively in said cavity. It is also possible to fix the liquefier positively and / or positively in or on the receptacle.
In a further embodiment of the invention it is provided that the cavity corresponds in its contour substantially to the contour of the condenser. It is conceivable that the receptacle has a wall which has one or more ribs which are arranged in such a way that the ribs extend into the region of the evaporation cup in which the condensate water is located during operation of the apparatus. These ribs thus serve to optimize the heat conduction from the condenser in the condensate-filled area of the evaporation tray.

Die Verdunstungsschale weist einen Boden auf wobei sich die wenigstens eine Rippe bis zum Boden der Verdunstungsschale erstreckt. Sind mehrere Rippen vorgesehen, ist es denkbar, dass diese in Umfangsrichtung der Aufnahme bzw. von deren Wandung beabstandet angeordnet sind.The evaporation tray has a bottom with the at least one rib extending to the bottom of the evaporation tray. If a plurality of ribs are provided, it is conceivable that they are arranged in the circumferential direction of the receptacle or spaced from the wall thereof.

Besonders vorteilhaft ist es, wenn die Aufnahme einen integralen Bestandteil der Verdunstungsschale bildet, wodurch sich eine besonders einfache Herstellbarkeit der Anordnung ergibt. Denkbar ist es beispielsweise die Verdunstungsschale mit der Aufnahme aus einem Kunststoffteil oder einem Metallteil, d. h. einstückig auszubilden. Grundsätzlich ist es ebenfalls denkbar, dass die Aufnahme und die eigentliche Verdunstungsschale zwei oder mehr als zwei Teile sind, die im Betriebszustand aneinander gefügt sind.It is particularly advantageous if the receptacle forms an integral part of the evaporation tray, resulting in a particularly simple manufacturability of the arrangement. It is conceivable, for example, the evaporation tray with the inclusion of a plastic part or a metal part, ie integrally form. In principle, it is also conceivable that the receptacle and the actual evaporation tray are two or more than two parts, which are joined together in the operating state.

Bei dem Verflüssiger kann es sich beispielsweise um einen Spiralverflüssiger handeln. Jedoch sind auch andere Verflüssigerformen denkbar. Möglich ist es, den Spiralverflüssiger derart auszuführen, dass mehrere, nebeneinander angeordnete Spiralen vorgesehen sind, die jeweils in einer bereits genannten Aufnahmen der Verdunstungsschale stehen.The condenser may be, for example, a spiral condenser. However, other condenser forms are conceivable. It is possible to carry out the spiral condenser such that a plurality of juxtaposed spirals are provided, which are each in an already mentioned recordings of the evaporation tray.

Grundsätzlich ist die Erfindung jedoch nicht hinsichtlich der Art und Anzahl der Verflüssiger beschränkt. Denkbar ist es ebenfalls, nur einen Spiralverflüssiger oder sonstigen Verflüssiger einzusetzen.In principle, however, the invention is not limited in terms of the type and number of condenser. It is also conceivable to use only a spiral condenser or other condenser.

Vorzugsweise ist der oder die Verflüssiger von der Aufnahme lösbar ausgeführt. Auf diese Weise ist es möglich, die Verdunstungsschale beispielsweise zu Reinigungszwecken abzunehmen.Preferably, the one or more liquefiers of the recording is carried out detachably. In this way it is possible to remove the evaporation tray, for example for cleaning purposes.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass die Verdunstungsschale einen ersten Bestandteil eines aus wenigstens zwei Teilen bestehenden Moduls bildet, das wenigstens einen zweiten Bestandteil aufweist, der Mittel zur Luftführung und/oder Mittel zur Führung des Kondenswassers und/oder Mittel zur Aufnahme einer oder mehrerer Komponenten des Gerätes und/oder Befestigungsmittel zur Befestigung des Moduls am Gerät aufweist.In a further embodiment of the invention, it is provided that the evaporation tray forms a first component of a module consisting of at least two parts, comprising at least a second component, the means for air guidance and / or means for guiding the condensed water and / or means for receiving a or comprising a plurality of components of the device and / or fastening means for fixing the module to the device.

Bei den genannten Komponenten des Gerätes, die in dem zweiten Bestandteil des Moduls angeordnet sind, kann es sich beispielsweise um einen Ventilator handeln, der die Luft über den Verflüssiger bzw. über die Verdunstungsschale führt. Ebenso kann vorgesehen sein, dass es sich bei der Komponente um den Verflüssiger selbst handelt. So ist es beispielsweise denkbar, dass der zweite Bestandteil die obere Aufnahme für den oder die Verflüssiger bildet.In the case of the named components of the device, which are arranged in the second component of the module, it may be, for example, a fan which conducts the air via the condenser or via the evaporation tray. It can also be provided that the component is the liquefier itself. For example, it is conceivable that the second component forms the upper receptacle for the condenser or condenser.

Auch ist es denkbar, dass mittels des zweiten Befestigungsteils Rohrdurchführungen insbesondere des Verflüssigers bzw. deren Abdichtungen realisiert werden. Auch kann in dem zweiten Bestandteil beispielsweise auch der Kondenswasserzulauf realisiert sein, durch den das Kondenswasser in die Verdunstungsschale hineinläuft.It is also conceivable that by means of the second fastening part pipe penetrations, in particular the condenser or its seals are realized. Also, in the second component, for example, the condensate inlet can be realized, through which the condensate runs into the evaporation tray.

In weiterer Ausgestaltung der Erfindung ist vorgesehen, dass der genannte Ventilator beispielsweise zu Servicezwecken von dem zweiten Bestandteil des Moduls abnehmbar ist.In a further embodiment of the invention it is provided that said fan is removable, for example, for service purposes of the second component of the module.

Bei dem Modul kann es sich beispielsweise um eine vormontierte Einheit handeln, was die Fertigung entsprechend vereinfacht.The module may be, for example, a preassembled unit, which simplifies the production accordingly.

Bei dem erfindungsgemäßen Kühl- und/oder Gefriergerät handelt es sich vorzugsweise um ein Unterbaugerät. Dabei kann vorgesehen sein, dass die genannte Anordnung bzw. das genannte Modul im Sockelbereich dieses Gerätes angeordnet ist.The refrigerator and / or freezer according to the invention is preferably an underbody device.

In Figur 1 ist mit dem Bezugszeichen 10 ein Modul dargestellt, dass in Form einer vormontierten Einheit hergestellt und sodann in den Sockelbereich eines Unterbaugerätes eingesetzt wird.In FIG. 1 Reference numeral 10 represents a module that is manufactured in the form of a preassembled unit and then inserted into the base area of a sub-assembly.

Das Modul 10 weist eine unten angeordnete Verdunstungsschale 12 und einen zweiten Bestandteil 14 auf, der verschiedene, unten näher beschriebene Funktionen erfüllt.The module 10 has a bottom arranged evaporation tray 12 and a second component 14, which fulfills various functions described in more detail below.

Die beiden Teile 12, 14 des Moduls 10 sind voneinander lösbar ausgeführt. Das Modul 10 kann somit beispielsweise für Reinigungs- oder Wartungszwecke zerlegt werden.The two parts 12, 14 of the module 10 are designed to be detachable from each other. The module 10 can thus be disassembled, for example, for cleaning or maintenance purposes.

Der untere Teil, d. h. die Verdunstungsschale 12 des Moduls 10 dient als Auffangschale für Kondenswasser aus dem Kühlgerät. Wie dies insbesondere aus Figur 2 hervorgeht, erstrecken sich vom Bodenbereich 13 der Verdunstungsschale 12 drei nebeneinander stehende Aufnahmen 14, die die Form senkrecht stehender Hohlzylinderabschnitte aufweisen, die an ihren Außenwandungen Rippen 16 aufweisen. Diese Aufnahmen 14 sind integrale Bestandteile der Verdunstungsschale 12, d. h. einstückig mit dem Boden 13 der Verdunstungsschale 12 verbunden.The lower part, ie the evaporation tray 12 of the module 10 serves as a collecting tray for condensed water from the refrigerator. How this particular out FIG. 2 it can be seen extending from the bottom portion 13 of the evaporation tray 12 three adjacent receptacles 14, which have the shape of vertical hollow cylinder sections having ribs 16 on their outer walls. These receptacles 14 are integral components of the evaporation tray 12, that is integrally connected to the bottom 13 of the evaporation tray 12.

In die Aufnahmen 14 eingesetzt ist ein Spiralverflüssiger 20, der in dem hier dargestellten Ausführungsbeispiel aus drei miteinander verbundenen spiralförmigen Bereichen 20a, 20b und 20c besteht, von denen jeder in einer Aufnahme 14 steht. Der Verflüssiger 20 verfügt über herkömmliche Zu- und Ablaufleitungen.Inserted in the receptacles 14 is a spiral condenser 20, which in the exemplary embodiment shown here consists of three interconnected spiral-shaped regions 20a, 20b and 20c, each of which is in a receptacle 14. The condenser 20 has conventional supply and discharge lines.

Erfindungsgemäß ist vorgesehen, dass der Verflüssiger 20 sowie dessen Zu- bzw. Ableitungen nicht in dem Bereich der Verdunstungsschale 12 angeordnet sind, der im Betrieb des Gerätes mit Kondenswasser gefüllt ist. Auf diese Weise ist es möglich, einen vergleichsweise aufwendigen und teuren Korrosionsschutz für den Verflüssiger 20 und dessen Zu- und Ablaufrohre zu verzichten. Gleichzeitig ermöglicht die untere Aufnahme 14 des Verflüssigers 20 auch die Entnahme der Verdunstungsschale 12 nach unten zur Reinigungszwecken.According to the invention, it is provided that the condenser 20 as well as its supply and discharge lines are not arranged in the region of the evaporation tray 12, which is filled with condensed water during operation of the device. In this way it is possible to dispense with a comparatively complicated and expensive corrosion protection for the condenser 20 and its inlet and outlet pipes. At the same time the lower receptacle 14 of the condenser 20 also allows the removal of the evaporation tray 12 down for cleaning purposes.

Durch die Aufnahmen 14, die aus vergleichsweise dünnwandigen Hohlzylinderabschnitten bestehen, kommt es zu einer guten Wärmeleitung der Verflüssigerabwärme in das in der Verdunstungsschale 12 stehende Kondenswasser. Dies wird nicht nur durch eine dünne Wandung, sondern zusätzlich durch die genannten Rippen 14 gelöst, die sich auf der Außenseite der Wandungen der Aufnahmen 14 erstrecken und bis zum Boden 13 der Verdunstungsschale 12 reichen.By the receptacles 14, which consist of relatively thin-walled hollow cylinder sections, there is a good heat transfer of Verflüssigerabwärme in standing in the evaporation tray 12 condensation. this will not only by a thin wall, but additionally solved by said ribs 14, which extend on the outside of the walls of the receptacles 14 and reach to the bottom 13 of the evaporation tray 12.

Der obere, zweite Bestandteil 14 des Moduls 10 beinhaltet eine nicht näher dargestellte Aufnahme für einen Ventilator und dient zur Luftführung über den Verflüssiger 20 bzw. über die Verdunstungsschale 12 sowie eine obere Aufnahme für den Verflüssiger 20. Der zweite Bestandteil 14 des Moduls, der unter anderem zur Luftführung dient, umgibt den Verflüssiger 20 und sitzt gleichsam als "Deckel" vollumfänglich auf der Verdunstungsschale 12 auf.The upper, second component 14 of the module 10 includes a receptacle not shown in detail for a fan and is used to guide air through the condenser 20 and via the evaporation tray 12 and an upper receptacle for the condenser 20. The second component 14 of the module serves for air flow, surrounds the condenser 20 and sits as it were as a "lid" fully on the evaporation tray 12.

Des Weiteren beinhaltet der zweite Bestandteil 14 den Kondenswasserablauf, sowie Befestigungsmittel zur Befestigung des Moduls 10 im Gerätesockel sowie eine Aufnahme von Abdichtungen der Rohrdurchführungen des Verflüssigers 20.Furthermore, the second component 14 includes the condensation drain, as well as fastening means for fastening the module 10 in the device base and a recording of seals of the pipe penetrations of the condenser 20th

Die Vorteile der vorliegenden Erfindung bestehen im Wesentlichen darin, dass durch den Wegfall von Korrosionsschutz-Beschichtungen des Verflüssigers ein Kostenvorteil erzielt wird, dass eine platzsparende Anordnung des Verflüssigers möglich ist, dass die Verflüssigerabwärme zur Kondenswasserverdunstung genutzt werden kann sowie dass eine schmutzunempfindliche Geometrie des Verflüssigers eingesetzt werden kann.The advantages of the present invention are essentially that a cost advantage is achieved by eliminating corrosion protection coatings of the condenser that a space-saving arrangement of the condenser is possible that the Verflüssigerabwärme can be used for condensate evaporation and that a dirt-insensitive geometry of the condenser used can be.

Durch die Modulbauweise ergibt sich eine kompakte Anordnung, wodurch der Vorteil erzielt wird, dass der Innenraum des Gerätes vergleichsweise groß gestaltet werden kann, da das Modul 10 relativ wenig Raum in Anspruch nimmt.Due to the modular design results in a compact arrangement, whereby the advantage is achieved that the interior of the device can be made comparatively large, since the module 10 takes up relatively little space.

Ein weiterer Vorteil der Anordnung besteht darin, dass eine gute Zugänglichkeit für den Kunden besteht und dass eine Entnahme des nicht dargestellten Ventilators im Servicefall ohne Weiteres möglich ist. Vorzugsweise sind die genannten Wartungs- bzw. Serviceschritte ohne Werkzeug ausführbar.Another advantage of the arrangement is that there is good accessibility for the customer and that a removal of the fan, not shown, in the case of service is readily possible. Preferably, said maintenance or service steps are executable without tools.
