Abstract
Description
Die vorliegende Erfindung betrifft ein Unterbaugruppenelement für ein Kühl-und/oder Gefriergerät sowie ein Kühl- und/oder Gefriergerät.The present invention relates to a subassembly element for a refrigerator and / or freezer as well as a refrigerator and / or freezer.
Aus dem Stand der Technik ist es bereits bekannt, bei Kühl- und/oder Gefriergeräten bodenseitig angeordnete Komponenten zu einer Unterbaugruppe bzw. einer sogenannten Gerätesockelbaugruppe zusammenzufassen und sodann als derart zusammengefasste Baugruppe mit dem Innenbehälter zusammenzufügen. Daran anschließend werden beispielsweise die Außenwandungen des Kühl- und/oder Gefriergerätes angebracht.It is already known from the prior art to combine components arranged on the bottom side in the case of refrigerators and / or freezers to form a subassembly or a so-called device base subassembly and then to assemble the subassembly thus combined with the inner container. Subsequently, for example, the outer walls of the refrigerator and / or freezer are attached.
Weiter ist bereits bekannt, bei Geräten keine Rückwandverflüssiger vorzusehen, sondern Kompressor und Verflüssiger im Sockelbereich anzuordnen. Hierzu werden beispielsweise im Gerätesockel Kompressor und Teile des Verflüssigerkreislaufs angeordnet. Über Luftführungskanäle, die im Gerätesockel angeordnet sind, werden die im Gerätesockel angeordneten Komponenten wie Kompressor und die Teile des Verflüssigerkreislaufs mit kalter Umgebungsluft beaufschlagt und hierdurch gekühlt. Problematisch erweist sich jedoch bei den bislang bekannten Vorschlägen aus dem Stand der Technik, dass diese die Komponenten im Sockelbereich nacheinander in den Luftführungskanälen anordnen, so dass keine optimale Belüftung der Komponenten gegeben ist, denn die von den weiter vorne in den Luftführungskanälen angeordneten Komponenten abgegebene Wärme führt zu einer Erwärmung der Luft in den Luftführungskanälen, so dass die nachgeordneten Komponenten ggf. nicht mehr ausreichend gekühlt werden können.Furthermore, it is already known to provide no rear wall condenser in the case of devices, but to arrange the compressor and condenser in the base area. For this purpose, for example, compressor and parts of the condenser circuit are arranged in the device base. Via air ducts, which are arranged in the device base, arranged in the device base components such as the compressor and the parts of the condenser circuit are exposed to cold ambient air and thereby cooled. However, problems with the hitherto known proposals from the prior art prove that these are the components in the base area Arrange successively in the air ducts, so that no optimal ventilation of the components is given, because the heat emitted by the further arranged in the air ducts components heat leads to a heating of the air in the air ducts, so that the downstream components may no longer be sufficiently cooled can be.
Es ist daher die Aufgabe der vorliegenden Erfindung, ein Unterbaugruppenelement der eingangs genannten Art in vorteilhafter Weise weiterzubilden, insbesondere dahingehend, dass eine Luftführung in dem Unterbaugruppenelement ermöglicht wird und dass eine optimale Belüftung aller in dem Unterbaugruppenelement angeordneten Komponenten ermöglicht werden kann.It is therefore the object of the present invention to develop a subassembly of the type mentioned in an advantageous manner, in particular to the effect that an air guide is made possible in the subassembly and that optimum ventilation of all components arranged in the subassembly can be made possible.
Diese Aufgabe wird erfindungsgemäß gelöst durch ein Unterbaugruppenelement mit den Merkmalen des Anspruchs 1. Danach ist vorgesehen, dass ein Unterbaugruppenelement, insbesondere ein Gerätesockel, für ein Kühl- und/oder Gefriergerät wenigstens zwei voneinander getrennte Luftführungsbereiche aufweist, die jeweils mit Luft zur Kühlung beaufschlagbar sind. Dadurch ergibt sich der Vorteil, die beispielsweise in den jeweiligen Luftführungsbereichen angeordneten Komponenten gesondert mit Luft zur Kühlung beaufschlagen zu können, wodurch eine bessere Kühlung und Wärmeabfuhr in den jeweiligen Luftführungsbereichen erzielbar ist.This object is achieved by a subassembly element with the features of claim 1. Thereafter, it is provided that a subassembly, in particular a device base, for a refrigerator and / or freezer at least two separate air ducts, each of which can be acted upon with air for cooling , This results in the advantage of being able to separately apply air for cooling to the components arranged, for example, in the respective air-guiding regions, as a result of which better cooling and heat dissipation in the respective air-guiding regions can be achieved.
Des Weiteren kann vorgesehen sein, dass der Luftführungsbereich zumindest teilweise kanalartig ausgebildet ist und/oder ein gemeinsamer Lufteinlass vorgesehen ist und/oder dass die Luftführungsbereiche jeweils wenigstens einen eigenen Luftauslass aufweisen.Furthermore, it may be provided that the air guidance area is at least partially channel-like and / or a common air inlet is provided and / or that the air guidance areas each have at least one air outlet of their own.
Ferner ist möglich, dass im Bereich des Lufteinlasses wenigstens ein Ventilator vorgesehen ist. Vorteilhafterweise ist somit möglich, mittels des Ventilators, der im Bereich eines gemeinsamen Lufteinlasses für die wenigstens zwei voneinander getrennten Luftführungsbereiche angeordnet ist, Umgebungsluft in die beiden Luftführungsbereiche einzublasen, wobei weiter vorzugsweise vorgesehen sein kann, dass die in die Luftführungsbereiche eingeblasene Luft, die dort zur Kühlung dient, jeweils über einen eigenen Luftauslass des jeweiligen Luftführungsbereichs wieder den Gerätesockel bzw. das Unterbaugruppenelement verlässt.It is also possible that at least one fan is provided in the region of the air inlet. Advantageously, it is thus possible, by means of the fan, which is arranged in the region of a common air inlet for the at least two separate air ducts to blow ambient air into the two air ducts, wherein more preferably can be provided that the blown into the air ducts air there to Cooling is used, each leaves its own air outlet of the respective air duct area the device base or the subassembly element.
Ferner ist möglich, dass der Lufteinlass frontseitig zwischen den beiden randseitigen Luftauslässen angeordnet ist und/oder dass der Lufteinlass durch einen Rahmen begrenzt ist und/oder dass der Lufteinlass mit einem Luftfilter versehen ist, der vorzugsweise den Lufteinlass vollständig abdeckt und mittels dessen die durch den Lufteinlass eintretende Luft filterbar ist, wobei der Luftfilter insbesondere in den Rahmen einsetzbar ist. Dadurch ergibt sich beispielsweise der Vorteil, dass Lufteinlass und Luftauslass ausschließlich frontseitig angeordnet sind, was insbesondere bei in Nischen oder wandnah angeordneten Kühl- und/oder Gefriergeräten von Vorteil ist. Besonders vorteilhaft ist es, wenn der Lufteinlass frontseitig zentrisch angeordnet ist. Durch den Luftfilter kann vorteilhafterweise verhindert werden, dass das Innere des Unterbaugruppenelements im Betrieb verschmutzt und somit auch einem Leistungsabfall der Komponenten des Kältekreislaufs, beispielsweise eines Verflüssigers entgegengewirkt werden kann. Denkbar ist insbesondere, dass der Luftfilter besonders einfach vom Nutzer des Kühl- und/oder Gefriergerätes entfernt werden kann. Dies kann beispielsweise dadurch erfolgen, dass der Kunde mittels einer Lasche den Luftfilter aus dem den Lufteinlass begrenzenden Rahmen herauszieht und einen Ersatzluftfilter in den Rahmen einsetzt. Denkbar ist auch, dass der Luftfilter nach einer Reinigung wiederverwendbar erneut in den Rahmen eingesetzt werden kann.It is also possible that the air inlet is arranged on the front side between the two peripheral air outlets and / or that the air inlet is limited by a frame and / or that the air inlet is provided with an air filter, which preferably completely covers the air inlet and by means of which by Air inlet entering air is filterable, the air filter is used in particular in the frame. This results, for example, in the advantage that the air inlet and outlet are arranged exclusively at the front, which is particularly advantageous in niches or close to the wall arranged cooling and / or freezers. It is particularly advantageous if the air inlet is arranged centrally on the front side. By means of the air filter, it is advantageously possible to prevent the interior of the subassembly element from being contaminated during operation and thus also from a drop in performance of the components of the refrigeration cycle, for example a condenser, being counteracted. It is conceivable, in particular, that the air filter can be removed particularly easily by the user of the refrigerator and / or freezer. This can be done, for example, that the customer by means of a tab pulls the air filter from the frame limiting the air inlet and inserts a replacement air filter in the frame. It is also conceivable that the air filter can be reused after cleaning in the frame again.
Darüber hinaus kann vorgesehen sein, dass in den Luftführungsbereichen jeweils Komponenten des Kältekreislaufes angeordnet sind, insbesondere Teile des bzw. der Verflüssiger(s), wobei der bzw. die Verflüssiger als Spiralverflüssiger ausgebildet ist bzw. sind. Dadurch ergibt sich der Vorteil, dass bei Geräten mit einer hohen Kühlleistung, die darüber hinaus ohne einen rückwandseitig angeordneten Verflüssiger bzw. Rückwandverflüssiger auskommen müssen, jeweils Verflüssiger in den Luftführungsbereichen angeordnet werden können. Zur Erhöhung der Oberfläche für die Wärmeabstrahlung werden die Verflüssiger vorteilhafterweise als Spiralverflüssiger ausgebildet. Da die Verflüssiger jeweils in den voneinander getrennten Luftführungsbereichen angeordnet sind, ist eine gleichmäßige und somit optimale Kühlung der Verflüssiger möglich, da diese parallel und nicht wie bislang seriell angeordnet sind.In addition, it can be provided that components of the refrigeration circuit are arranged in each case in the air-guiding regions, in particular parts of the condenser (s), the condenser or condensers being or being designed as spiral condenser. This has the advantage that in the case of devices with a high cooling capacity, which in addition have to make do without a condenser or rear wall condenser arranged on the back wall side, in each case condenser can be arranged in the air guide areas. To increase the surface for the heat radiation, the condenser are advantageously formed as a spiral condenser. Since the condenser in each case in the separate Air ducts are arranged, a uniform and thus optimal cooling of the condenser is possible because they are arranged in parallel and not as previously serial.
Des Weiteren kann vorgesehen sein, dass wenigstens ein Bypassbereich, insbesondere ein Bypasskanal vorhanden ist, mittels dessen Luft zu einer Verdunstungsschale führbar ist und/oder mittels dessen Luft zu wenigstens einem Kompressor führbar ist, wobei der Kompressor vorzugsweise in dem Unterbaugruppenelement angeordnet ist. Dadurch wird es möglich, mittels des Bypasskanals eine Verdunstungsschale dynamisch zu belüften, wodurch die Verdunstungsleistung steigt. Vorteilhafterweise ist denkbar, dass die Verdunstungsschale mit einem Deckel ausgeführt ist, in welchem Lüftungsöffnungen vorgesehen sind, wodurch die warme Luft beispielsweise an der Geräterückwand des Kühl- und/oder Gefriergeräts hochströmen kann. Durch dieses Hochströmen der warmen Luft kann eine Betauung der Geräterückwand vermieden werden. Dies ist insbesondere dann von Vorteil, wenn das Gerät über keinen Rückwandverflüssiger verfügt, der aufgrund seiner Wärmeabstrahlung eine Betauung der Rückwand verhindert. Dies ist insbesondere bei Geräten von Vorteil, die für den Einsatz in Ländern mit hoher Luftfeuchtigkeit und hoher Umgebungstemperatur vorgesehen sind. In diesem Zusammenhang ist ebenfalls denkbar, dass eine dynamische Belüftung der Rückwand vorgesehen ist, was durch eine entsprechende Ansteuerung bzw. Regelung des Ventilators erreicht werden kann. Eine derartige dynamische Belüftung der Rückwand ist insbesondere dann von Vorteil, wenn zwischen Gerät und Wand ein zu geringer Abstand besteht, um genügend Luft durch natürliche Konvektion an der Rückwand aufsteigen zu lassen.Furthermore, it can be provided that at least one bypass region, in particular a bypass channel is present, by means of which air can be guided to an evaporation tray and / or by means of which air can be guided to at least one compressor, wherein the compressor is preferably arranged in the subassembly element. This makes it possible to dynamically aerate an evaporation tray by means of the bypass channel, whereby the evaporation performance increases. Advantageously, it is conceivable that the evaporation tray is designed with a lid in which ventilation openings are provided, whereby the warm air can flow, for example, on the rear wall of the refrigerator and / or freezer. Through this high flow of warm air condensation of the rear panel can be avoided. This is particularly advantageous if the device has no back wall condenser, which prevents condensation of the rear wall due to its heat radiation. This is particularly advantageous for devices that are intended for use in countries with high humidity and high ambient temperature. In this context, it is also conceivable that a dynamic ventilation of the rear wall is provided, which can be achieved by a corresponding control or regulation of the fan. Such a dynamic ventilation of the rear wall is particularly advantageous if there is too little space between the device and the wall to allow sufficient air to rise through natural convection on the rear wall.
Bevorzugt wird es, wenn der Kompressor im hinteren Bereich des Unterbaugruppenelementes bzw. eines Teils des Unterbaugruppenelementes angeordnet ist und/oder dass die Verdunstungsschale oberhalb des Kompressors angeordnet ist. In einer derartigen Anordnung ergibt sich der Vorteil, dass die durch den Lufteinlass mittels des Ventilators eingesaugte und über die Bypasskanäle auf die Kompressoren bzw. den Kompressor beaufschlagte Luft zunächst die Kompressoren kühlt und sodann die hierdurch erwärmte Luft in die Verdunstungsschale geführt wird, wodurch die Verdunstungsleistung gesteigert werden kann. Besonders vorteilhaft ist in diesem Zusammenhang, wenn über die deckelseitigen Luftaustrittsöffnungen der Verdunstungsschale die sehr warme Luft an der Rückwand des Kühl- und/oder Gefriergerätes entlang aufsteigen kann.It is preferred if the compressor is arranged in the rear region of the subassembly or a part of the subassembly and / or that the evaporation tray is arranged above the compressor. In such an arrangement, there is the advantage that the air sucked through the air inlet by means of the fan and acted upon by the bypass channels on the compressors or the compressor air first cools the compressors and then the air thus heated is fed into the evaporation tray, whereby the evaporation performance can be increased. In this context, it is particularly advantageous if the very warm air can rise along the rear wall of the refrigerating and / or freezing appliance via the cover-side air outlet openings of the evaporation tray.
Außerdem kann vorgesehen sein, dass in den Luftauslässen bzw. in den Bereichen der Luftauslässe wenigstens ein luftströmungsablenkendes Mittel vorgesehen ist, mittels dessen eine Kurzschlussströmung mit anderen Luftführungsbereichen verhinderbar ist, insbesondere, dass mittels des wenigstens einen luftströmungsablenkenden Mittels Kurzschlussströmungen von dem Lufteinlass und den Luftauslässen verhinderbar sind.In addition, it can be provided that at least one Luftströmungsablenkendes means is provided in the air outlets or in the areas of the air outlets, by means of which a short-circuit flow can be prevented with other air ducts, in particular by means of at least one Luftströmungsablenkenden means shortcircuit flows of the air inlet and the air outlets prevented are.
Besonders vorteilhaft ist es, wenn das luftströmungsablenkende Mittel einteilig an den jeweiligen Luftauslass angeformt ist und/oder dass das luftströmungsablenkende Mittel ein Luftauslassgitter mit schrägstehenden Lamellen ist. Beispielsweise kann bei einer Anordnung, bei der der Lufteinlass frontseitig zwischen den beiden Luftauslässen angeordnet ist, vorgesehen sein, dass die Luftauslässe jeweils ein Luftauslassgitter aufweisen, dessen schräg stehende Lamellen die austretende Luftströmung von der Mitte weg nach außen hin jeweils ablenken.It is particularly advantageous if the air flow deflecting means is integrally formed on the respective air outlet and / or that the air flow deflecting means is an air outlet grille with inclined blades. For example, in an arrangement in which the air inlet is arranged on the front side between the two air outlets, it can be provided that the air outlets each have an air outlet grille whose obliquely arranged fins divert the outgoing air flow away from the center to the outside.
Des Weiteren betrifft die vorliegende Erfindung ein Kühl- und/oder Gefriergerät mit den Merkmalen des Anspruchs 10. Danach ist vorgesehen, dass ein Kühl- und/oder Gefriergerät wenigstens ein Unterbaugruppenelement nach einem der Ansprüche 1 bis 9 aufweist.Furthermore, the present invention relates to a refrigerator and / or freezer with the features of
