Abstract
Description
Die Erfindung betrifft ein allgemein bekanntes Kältegerät mit einem wärmeisolierenden Gehäuse, innerhalb welchem wenigstens ein on einer Innenverkleidung ausgekleideter Lagerraum vorgesehen ist, welcher von einem flächenhaften, in wärmeleitendem Kontakt mit der Innenverkleidung stehenden Verdampfer gekühlt ist, welcher in der Wärmeisolation des Gehäuses angeordnet ist.The invention relates to a generally known refrigerator with a heat-insulating housing, inside which is provided at least one storage space lined on an inner lining which is from a flat, in heat-conducting contact with the inner lining standing evaporator is cooled, which in the thermal insulation of the housing is arranged.
Bei Kühlgeräten ist es seit langem Stand der Technik, daß deren zum Kühlen ihres Kühlraumes dienende Verdampferplatinen in die Wärmeisolation des Kühlgerätegehäuses eingebettet sind und in wärmeleitendem Kontakt mit einer den Kühlraum des Gerätes auskleidenden Innenverkleidung stehen. Diese Art der Verdampfer, welche auch als sogenannte cold-wall-Verdampfer bezeichnet sind, haben zwar den Vorteil, daß sie nutzvolumensteigernd außerhalb des Kühlraumes angeordnet und somit dessen überwiegend glatten Wände meist leicht zu reinigen sind. Die durchaus gängige Maßnahme, die Verdampfer durch Einschäumen in den Wärmeisolationsschaum mit einzubetten, bringt bedingt durch den benetzenden Wärmeisolationsschaum jedoch mit sich, daß die Verdampferplatinen in direktem flächigen Kontakt mit dem Wärmeisolationsschaum stehen. Dies hat zur Folge, daß von der Verdampferplatine beispielsweise durch das Einspritzen des zur Kühlung dienenden Kältemittels in die Verdampferplatine mit hohen Geschwindigkeiten Geräusche ausgehen, welche die Folge von geschwindigkeitsbedingt verursachten Turbulenzen sind, welche die Verdampferplatine zu Schwingungen anregen. Diese Schwingungen werden durch die Ankopplung des zur Wärmeisolierung verwendeten Schaumes an die Verdampferplatine an ersteren übertragen. Da der Wärmeisolationsschaum Körperschall gut leitet, werden die von der Verdampferplatine abgegebenen Strömungs- und Einspritzgeräusche durch die weitere Ankopplung des Wärmeisolationsschaumes an die äußeren Gehäuseschalen des Kühlgerätegehäuses von diesem als Luftschall abgestrahlt. Die vom Gerätegehäuse abgestrahlten Schallwellen, welche auf die zeitlich nicht konstanten Strömungs- und Einspritzgeräusche des Kältemittels in die Verdampferplatine zurückzuführen sind, wirken je nach Aufstellungsort des Kühlgerätes auf den Endverbraucher nicht nur störend, sondern können diesen hinsichtlich einer einwandfreien Funktion des Kühlgerätes in Zweifel setzen, da die Geräuschquelle für den Endverbraucher nicht lokalisierbar ist.In cooling devices, it has long been state of the art that their for cooling their Evaporator boards serving the cooling space in the thermal insulation of the cooling device housing are embedded and in heat-conducting contact with the cooling chamber of the Inner lining of the unit. This type of vaporizer, which are also referred to as so-called cold wall evaporators, but have the advantage that they are arranged outside the cold room and thus increase its useful volume mostly smooth walls are usually easy to clean. The most common Measure the evaporator by foaming it in the heat insulation foam embedding, however, due to the wetting thermal insulation foam with itself that the evaporator boards in direct surface contact with the heat insulation foam stand. This has the consequence that, for example, of the evaporator board by injecting the cooling refrigerant into the evaporator board emit noise at high speeds, which is the result of are turbulence caused by speed, which the evaporator board to stimulate vibrations. These vibrations are due to the coupling of the foam used for thermal insulation on the evaporator board on the former transfer. Since the heat insulation foam conducts structure-borne sound well, the flow and injection noises emitted by the evaporator board the further coupling of the thermal insulation foam to the outer housing shells of the cooling unit housing is radiated by this as airborne sound. The from the device housing radiated sound waves, which affect the temporally not constant flow and injection noise of the refrigerant into the evaporator board depending on the location of the cooling unit End users are not only annoying, but can do this with regard to a doubt the proper functioning of the cooling unit, as the source of the noise the end consumer cannot be localized.
Der Erfindung liegt die Aufgabe zugrunde, ein Kältegerät gemäß dem Oberbegriff des Anspruches 1 mit einfachen konstruktiven Maßnahmen hinsichtlich der Schallabgabe zu verbessern.The invention has for its object a refrigerator according to the preamble of Claim 1 with simple constructive measures with regard to sound emission to improve.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß der Verdampfer mit seine Masse erhöhenden Mitteln versehen ist, durch welche der Verdampfer für betriebsbedingt auf ihn einwirkende Erregerfrequenzen weitestgehend schwingungssteif ausgebildet ist.This object is achieved according to the invention in that the evaporator with its mass-increasing means is provided, by which the evaporator for operational reasons excitation frequencies acting on it as far as possible is designed to be vibration-resistant.
Durch die Erhöhung der Masse des Verdampfers läßt sich dieser durch die betriebsbedingt auftretenden Erregerschwingungen, verursacht durch Turbulenzen des mit hoher Strömungsgeschwindigkeit im siedenden Zustand in die Verdampferplatine eingespritzten Kältemittels, deutlich weniger anregen. Durch die verminderte Anregung befindet sich die Verdampferplatine trotz der auf sie einwirkenden, als Strömungs- und Einspritzgeräusche wahrnehmbaren Turbulenzen zumindest weitestgehend im Ruhezustand, so daß trotz der dem Wärmeisolationsschaum anhaftenden guten Leiteigenschaften für Körperschall die Schallabgabe des Gerätegehäuses so stark vermindert ist, daß die Einspritz- und Strömungsgeräusche für einen Endverbraucher nicht mehr wahrnehmbar sind.By increasing the mass of the evaporator, this can be caused by the operation excitation vibrations, caused by turbulence of the high Flow velocity in the boiling state injected into the evaporator board Refrigerant, stimulate significantly less. Due to the diminished excitation the evaporator board despite acting on it, as a flow and Injection noises perceptible turbulence at least largely in the idle state, so that despite the good conductive properties adhering to the heat insulation foam for structure-borne noise, the sound emission of the device housing is reduced so much is that the injection and flow noise is no longer for an end user are noticeable.
Entsprechend einer bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß die Mittel wärmeisolationsseitig auf den Verdampfer aufgebracht sind.According to a preferred embodiment of the subject of the invention it is provided that the means are applied to the evaporator on the heat insulation side are.
Durch die wärmeisolationsseitige Anbringung der Mittel zur Erhöhung der Masse des Verdampfers ist die Verdampferplatine an den mit den Mitteln zur Masseerhöhung versehenen Bereichen nicht mehr unmittelbar mit dem benetzend wirkenden Wärmeisolationsschaum verbunden ist, so daß dieser als Leiter für den Körperschall zumindest bereichsweise von der Verdampferplatine entkoppelt und somit eine weitere Geräuschminimierung des Kühlgerätes erzeugt ist. By attaching the means to increase the mass of the heat insulation side Evaporator is the evaporator board on the provided with the means for increasing the mass Areas no longer directly with the wetting heat insulation foam is connected, so that this at least as a conductor for structure-borne noise decoupled from the evaporator board in some areas and thus further noise minimization of the refrigerator is generated.
Besonders einfach auf die Verdampferplatine aufbringbar sind die Mittel zur Masseerhöhung, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß die Mittel als folienähnlicher Werkstoff ausgebildet sind.The means for increasing the mass are particularly easy to apply to the evaporator board, if after a next advantageous embodiment of the subject Invention is provided that the means are designed as a film-like material.
Gemäß einer nächsten bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß der folienartige Wirkstoff biegeweich ausgeführt ist.According to a next preferred embodiment of the subject of the invention it is provided that the film-like active ingredient is designed to be flexible.
Ein biegeweicher Werkstoff bringt den zusätzlichen Vorteil mit sich, daß er den Konturen an der Verdampferplatinenoberfläche problemlos zu folgen vermag und somit die Beschichtung der Verdampferplatine vereinfacht ist. Zugleich ist durch die konturengenaue Anpassung der Folie sichergestellt, daß diese an der Platinenoberfläche anliegt und somit im Fertigungsprozeß eine Hinterfüllung der Folie mit Wärmeisolationsmaterial im wesentlichen angeschlossen ist.A flexible material has the additional advantage that it has the contours can easily follow on the evaporator board surface and thus the Coating the evaporator board is simplified. At the same time is due to the precise contours Adjusting the film ensures that it lies against the surface of the board and thus a backfilling of the film with heat insulation material in the manufacturing process is essentially connected.
Ein besonders günstiges Geräuschverhalten für ein Kältegerät durch die vollkommene Entkopplung des Wärmeisolationsschaumes von der Verdampferplatine ist erreicht, wenn nach einer nächsten vorteilhaften Ausgestaltung des Gegenstandes der Erfindung vorgesehen ist, daß der folienartige und biegeweiche Werkstoff die wärmeisolationsseitige Fläche des Verdampfers weitestgehend bedeckt.A particularly favorable noise behavior for a refrigerator due to the perfect Decoupling of the heat insulation foam from the evaporator board has been achieved if after a next advantageous embodiment of the subject of the invention it is provided that the film-like and flexible material the heat insulation side Evaporator surface largely covered.
Besonders günstige Dämpfungseigenschaften weist der folienähnliche und biegeweiche Werkstoff auf, wenn nach einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß der folienartige und biegeweiche Werkstoff als Schwergummimatte ausgeführt ist.The film-like and flexible material has particularly good damping properties Material on if according to a further preferred embodiment of the object the invention provides that the film-like and flexible Material is designed as a heavy rubber mat.
Zugleich ist durch die Schwergummimatte eine deutliche Gewichtserhöhung der Verdampferplatine erreicht.At the same time, the heavy rubber mat significantly increases the weight of the evaporator board reached.
Besonders leicht verarbeiten läßt sich der folienähnliche und biegeweiche Werkstoff, wenn nach einer alternativen Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß der folienartige und biegeweiche Werkstoff als Bitumenfolie ausgebildet ist. The film-like and flexible material is particularly easy to process, if provided according to an alternative embodiment of the subject of the invention is that the film-like and flexible material is designed as a bitumen film is.
Entsprechend einer weiteren bevorzugten Ausführungsform des Gegenstandes der Erfindung ist vorgesehen, daß der folienähnliche und biegeweiche Werkstoff die Masse des Verdampfers um wenigstens 25% erhöht.According to a further preferred embodiment of the subject of Invention is provided that the film-like and flexible material Evaporator mass increased by at least 25%.
Durch eine derartige Masseerhöhung ist nicht nur erreicht, daß sich der Verdampfer von den betriebsbedingt auftretenden Turbulenzen deutlich weniger anregen läßt, sondern auch, daß sich die Verdampferplatine für das Fertigungspersonal in der Serienfertigung auch noch vernünftig handhaben läßt.Such an increase in mass not only achieves that the evaporator from the turbulence that occurs during operation can be stimulated significantly less, but also that the evaporator board for the manufacturing staff in series production can also be handled properly.
Eine besonders geringe Geräuschemission für ein Kältegerät ist erreicht, wenn nach einer letzten bevorzugten Ausführungsform des Gegenstandes der Erfindung vorgesehen ist, daß der folienähnliche und biegeweiche Werkstoff schallabsorbierende Eigenschaften aufweist.A particularly low noise emission for a refrigerator is achieved if after a last preferred embodiment of the subject of the invention provided is that the film-like and flexible material has sound-absorbing properties having.
Die Erfindung ist in der nachfolgenden Beschreibung am Beispiel eines in der Zeichnung vereinfacht dargestellten Haushaltskühlschrankes erläutert.The invention is in the following description using the example of one in the drawing Household refrigerator illustrated in simplified form.

Fig. 1 zeigt einen vereinfacht schematisch dargestellten Tischkühlschrank 10, dessen
frontseitig mit einer wärmeisolierenden Tür 11 versehenes Gehäuse 12 eine Kunststoffinnenverkleidung
13, eine dazu beabstandete Außenverkleidung 14 und einen in
flüssigen Ausgangskomponenten zwischen den Verkleidungen 13 und 14 eingebrachten
Wärmeisolationsschaum 15 aufweist, welcher durch seine adhäsive Wirkung an
den Verkleidungen 13 und 14 anhaftet und dadurch dem wärmeisolierenden Gehäuse
12 seine Steifigkeit verleiht. Innerhalb des wärmeisolierenden Gehäuses 12 ist in dessen
oberem Abschnitt ein ***-Gefrierfach 16 vorgesehen, welches durch eine wärmeisolierend
ausgeführte Gefrierfachtür 17 separat verschließbar ist und welches durch
eine wärmeisolierende Zwischenwand 18 an einem unterhalb dem Gefrierfach 16 angeordneten
Normalkühlfach 19 wärmeisolierend getrennt ist. Das Normalkühlfach 19
ist mit in gleichmäßigen Abständen übereinander angeordneten, zur Ablage von Kühlgut
dienenden Kühlgutablagen 20 versehen und von einem zu einer Verdampferplatine
21 gehörenden, durch einen Platinenabschnitt gebildeten Verdampfer 22 gekühlt, welcher
an der der Tür 11 gegenüberliegenden Rückseite des Kühlfaches 19 angeordnet
ist. Der mit einer nach dem Rollbond-Verfahren hergestellten Kältemitteikanalanordnung
23 ausgestattete Verdampfer 22 ist wärmeisolationsseitig in wärmeleitendem
Kontakt auf die Rückseite der Innenvekleidung 13 aufgebracht und über nicht näher
bezeichnete Verbindungskanäle mit einem im Querschnitt im wesentlichen U-förmig
ausgebildeten Verdampfer 24 strömungstechnisch verbunden. Der aus einem zweiten
Platinenabschnitt der Verdampferplatine 21 herausgeformte Verdampfer 24 weist wie
der Verdampfer 22 eine nach dem Rollbond-Verfahren hergestellte Kältemittelkanalanordnung
25 auf und ist mit seiner ebenen Platinenseite wie der Verdampfer 22 in
wärmeleitendem Kontakt auf die dem Wärmeisolationsschaum 15 zugewandte Außenseite
der Gefrierfachinnenverkleidung 13 aufgebracht. Die Kältemittelkanalanordnung
25 weist eine Kältemitteleinspritzstelle 26 auf, weiche durch Prägung eines nicht näher
dargestellten Drosselrohres erzeugt ist (siehe hierzu Fig. 2).Fig. 1 shows a
Wie insbesondere aus Fig. 2 hervorgeht, ist der Verdampfer 24 auf seiner mit den
Ausprägungen für die Kältemittelkanalanordnung 25 versehenen Oberfläche mit einer
zum Erhöhung seiner Masse um wenigstens 25% dienenden Mitteln versehen, weiche
im vorliegenden Fall als folienähnlicher Werkstoff 27 ausgebildet sind. Der folienähnliche
Werkstoff 27, welcher beispielsweise durch eine Bitumenfolie oder eine Schwergummimatte
gebildet sein kann, bedeckt die gesamte, den Wärmeisolationsschirm 15
zugewandte Oberfläche des Verdampfers 24 und ist biegeweich ausgeführt, wodurch
die folienähnliche Matte 27 in der Lage ist, den Konturen der Kältemittelkanalanordnung
25 zu folgen. Durch die auf die wärmeisolationsseitige Oberfläche des Verdampfers
24 aufgeklebte folienähnliche Matte 27 ist der als guter Leiter für Körperschall erkannte
Wärmeisolationsschirm 15 nicht mehr direkt mit dem Verdampfer 24 kontaktiert,
so daß letzterer von dem Wärmeisolationsschaum 15 entkoppelt ist. Eine besonders
intensive Entkopplung ist dann erreicht, wenn die folienähnliche Matte 27 neben
den zur Gewichtserhöhung des Verdampfers 24 dienenden Eigenschaften zusätzlich
schwingungsdämpfende Eigenschaften aufweist, in diesem Fall sind die die Verdampferplatine
in Schwingungen zu versetzen vermögenden Turbulenzen, welche durch das
mit hoher Geschwindigkeit in siedendem Zustand zur Einspritzstelle 26 geförderte
Kältemittel verursacht werden, nicht nur durch die infolge der Masseerhöhung deutlich
schwingungssteifere Ausbildung des Verdampfers, sondern zusätzlich durch die
dampfende Wirkung der Matte 27 abgefangen. Allein durch die Masseerhöhung des
Verdampfers 24, bewirkt durch die folienähnliche Matte 27, ist ein für die betriebsbedingt
auf den Verdampfer 24 einwirkenden Erregerfrequenzen, hervorgerufen durch
die sich bildenden Turbulenzen des eingespritzten Kältemittels derart schwingungssteif,
daß auf den Wärmeisolationsschaum 15 eine Übertragung von Körperschall,
ausgehend von dem Verdampfer 24, zumindest im wesentlichen vermieden ist.As can be seen in particular from FIG. 2, the
