Definitions
- Refrigeration appliances with automatic defrosting function conventionally have an evaporation tray which is accommodated together with the compressor in an open compartment of the refrigeration appliance housing.
- the evaporation tray serves to trap and evaporate condensation water, which precipitates on a vaporizer arranged on the cooling space of the refrigeration device.
- Such an evaporation tray must have sufficient power to evaporate under any operating conditions, the accumulating condensation, as overflow of the shell could cause water reaches live parts of the compressor or its environment.
- various parameters are important, such as the free liquid surface in the shell, its temperature and an unobstructed air circulation between the shell and the environment of the refrigerator.
- the evaporation tray may be mounted directly on the compressor or on the walls of a compartment which receives it together with the compressor.
- the immediate attachment of the evaporation tray on the compressor has the advantage that an efficient heat transfer from the compressor to the shell and thus a high water temperature and a correspondingly high evaporation performance can be achieved.
- a disadvantage of this design is that for each type of compressor a suitable evaporation tray must be specially designed and manufactured and the compressor can be installed only with the specially suitable for him shell in a refrigerator. In the mass production of refrigerators, however, it would be desirable compressors of different manufacturers or makes that can differ in their housing form, to be able to install in conjunction with a same model of evaporation tray.
- the need to assemble compressors and evaporation tray prior to their installation in a refrigeration device complicate the installation of the refrigerator because the evaporation tray blocks access to fasteners or hindered.
- the evaporation tray is mounted in the compartment independent of the compressor; but then other disadvantages must be accepted. Since the temperature in the shell, and thus its evaporation performance, depends on the distance of the shell to the compressor, the evaporation performance of a shell may prove inadequate if used with a compressor of lesser height, rather than the compressor for which it was originally designed is, even if this provides the same heat output. As a result, it also does not allow the evaporation tray independent of the compressor to employ a uniform model of evaporation cups in combination with different compressor models.
- document JP 2000 292 051 A discloses a refrigerator according to the preamble of claim 1.
- the object of the present invention is to provide a refrigeration device which allows the use of gleichformformten evaporation trays in conjunction with different compressor models.
- the brackets each have supporting surfaces on which rest side webs of the evaporation tray.
- the holders In order to prevent accidental mounting of the evaporation tray in an inappropriate height, the holders each have a coding associated with it, which allows the mounting of the provided with a complementary coding evaporation tray only on each one of these brackets.
- the coding of the evaporation tray is a recess and in which the holder around a projection which engages in the recess, so on located at the bottom bracket such a coding dispensable, since an evaporation tray on this holder is anyway only mountable when installed by several different in the refrigerator mountable compressor models, the model with the minimum height. Thus, an erroneous assembly of the shell at the bottom bracket in conjunction with a false compressor model per se is excluded. However, the accidental mounting of the evaporation tray on a too high mount when using a compressor with low height is prevented by the coding
- the coding of the shell is a projection and that of the holder is a recess in which engages the projection, it can be omitted for an analogous reason, a coding of the top bracket.
- the mounting of the evaporation tray can e.g. take place in which this is placed in the manner of a drawer with their webs on a holder and then inserted into the compartment.
- the evaporation tray can be brought by pivoting about a vertical axis against its mounted position or removed from this position. This has the advantage that jamming and sticking of the shell during assembly is not possible.
- this axis crosses one of the webs of the evaporation tray.
- This, and the pivoting mobility of the shell, allows the coding to be applied to the lateral web which is crossed by the axle.
- This has the advantage that the coding can be located at a location close to the open side of the tray and remains visible during assembly of the tray. If an inexperienced person inadvertently tries to mount the tray in a wrong fixture and fails to do so, they can easily identify the reason and choose the correct fixture.
- the coding of the evaporation shell is formed by at least one projection which faces upwards from the web and which is in assembled state engages in a complementary recess on a side wall of the compartment.
- This coding is preferably formed by a body formed in two parts with the evaporation shell, which can be fastened in a plurality of positions on the evaporation shell. This makes it possible to produce evaporation trays with a same shape suitable for different compressor models in large numbers and by attaching the coding only for a specific model of compressor specific adapt when it is clear which model is actually to be installed.
- locking means are preferably provided for locking the evaporation tray in the mounted position.
- a locking means can be formed by a locking clip attached to the web remote from the axis of rotation.
- a compression spring is disposed between the evaporation tray and a rear wall of the tray.
- this compression spring is a leaf spring formed integrally with the evaporation tray.
- Fig. 1 shows a rear view of the housing 1 of a refrigerator, which is to be considered as an example of a refrigerator according to the invention.
- a compressor 3 and an evaporation tray 4 are housed in a lower region of the back of the housing 1.
- connections 5 of the compressor which are provided for connection to a condenser or evaporator, are still unconnected.
- connection 5 of the compressor which are provided for connection to a condenser or evaporator, are still unconnected.
- connection 5 of the compressor which are provided for connection to a condenser or evaporator, are still unconnected.
- connection 5 of the compressor which are provided for connection to a condenser or evaporator, are still unconnected.
- connection 5 of the compressor which are provided for connection to a condenser or evaporator
- FIGS. 2 and 3 show two perspective views of the tray 2, each with mounted therein compressor 3, but without evaporation tray 4.
- upper portion of the compartment 2 between the compressor 3 and the ceiling 7 of the compartment are on its side walls. 8 , 9 two holders for an evaporation tray arranged one above the other.
- Each support comprises a horizontal groove 10a, 10b in the side wall 8, and opposite at the same height, a horizontal groove 11a, 11b in the side wall 9.
- the grooves 10a, 10b extend continuously from the open front of the compartment 2 to its rear wall 12.
- the side wall 8 of the compartment is not perpendicular to the back of the housing 1, but extends in its the open front of the compartment 2 facing region slightly oblique and is in its rear wall 12 of the compartment 2 facing rear portion swung such that the Width of the tray 2 to the rear wall 12 decreases towards.
- tongue 13 two openings 14a, 14b are respectively formed in extension of the grooves 10a, 10b.
- each groove 11a, 11b of the side wall 9 lying toward the outside of the housing 1 a short recess 16 is cut off in each case by a vertical rib 15 at its end facing the open rear side.
- a recess 17 a, 17 b is formed at different distances from the rib 15 each have a recess 17 a, 17 b.
- the recess 17a or 17b has the function of a coding for the assembly of the evaporation tray 4, as will become clearer later.
- Fig. 4 is a perspective view of the evaporation tray 4 Fig. 1 ,
- the evaporation tray 4 is divided by partitions 18, 19, 20, 21 into a plurality of basins 22, 23, 24, 25, 26, 27.
- the bottom of the shell is shaped according to the shape of the top of the compressor 3, over which it is to be mounted, so that the basins 22 to 27 each have different depths.
- the shallowest basin 22, which is arranged centrally in the shell 4 comes when the evaporation tray 4 is mounted in the compartment 2, under a in Fig. 2 shown outlet opening 28 to lie in the ceiling 7 of the compartment 2, so that from the refrigerator of the refrigerator through the drain opening 28 expiring condensate first fills the basin 22. Only when this overflows, the condensation reaches the surrounding pool 23.
- the basins 23 to 27 are connected to each other by cutouts 29 in the partitions 19, 20, so that if the evaporation capacity of a pool is insufficient, the respective following is flooded and so the evaporation surface is increased.
- An overflow pipe 30 in the last tank 27 allows in an emergency a controlled flow of condensation out of the refrigerator out without risk of live parts in the second
- the evaporation tray 4 has an approximately trapezoidal ground plan, with a front side 31 facing the open side of the compartment 2, an approximately parallel rear side 32 which is shorter than the front side 31, facing the front wall 31 and rear side 32 facing the side wall 9 Side edge 33 and an obliquely and partially rounded extending side wall 8 facing the side edge 34.
- Side edge 33 and an obliquely and partially rounded extending side wall 8 facing the side edge 34 are horizontal webs 35, 36 formed on the shell 4, which in the assembled state of the shell 4 on the undersides of the grooves 10, 11 a or 10b, 11 b rest.
- a short pin 40 is divided by a cut 39.
- the pin 40 is provided to be inserted obliquely from the side into one of the recesses 16 during assembly of the evaporation tray 4.
- the engagement between pin 40 and recess 16 defines a vertical pivot axis about which the evaporation cup 4 can be pivoted to be further inserted into the compartment 2.
- Fig. 4 shows two projections or pins 41 which project from the web 35 upwards.
- the evaporation tray 4 is provided with only one of these two pins 41.
- the pin 41 may be formed integrally with the shell; Preferably he is subsequently attached to the shell 4, for example by a permanent locking.
- the two possible mounting positions of the pins 41 respectively correspond to the position of the recesses 17a, 17b on the grooves 11a, 11b.
- How to make a synopsis of the Figures 3 and 4 easily recognizes is a shell 4, when it is equipped in the front position with a pin 41, only in the upper 11 a of the two grooves 11 a, 11 b inserted, when fitted in the rear position only in the lower groove 11 b ,
- the web 36 carries at its front end a locking clip, which, when the evaporation tray 4 is inserted correctly, in one of the openings 14 of the tongue 13 engages.
- the pin 41 abuts against the side wall 9 before such locking is possible and thus blocks further insertion of the tray 4 into the tray 2.
- a integrally formed on the back 32 of the shell 4 leaf spring 38 presses in the locked state of the evaporation tray 4 against the rear wall 12 of the tray 2 and so keeps the shell 4 under tension so that outgoing vibrations from the compressor 3 in operation does not cause a rattling of the shell 4 can lead.
- Fig. 5 shows a perspective view of the tray 2 with mounted above the compressor 3 evaporation tray 4.
- the lateral webs of the evaporation tray lie respectively in the lower grooves 10b and 11b, and the pin 41 of the shell 4 engages in the recess 17b of the lower groove 11 b ,
- the locking clip 37 is snapped on the lower opening 14 b of the tongue 13.
- An appropriate assembly of the shell 4 to the Higher lying grooves 10 a, 11 a would not be possible, since here the position of the recess 17 a does not match that of the pin 41. So it is impossible that the shell 4 is inadvertently installed too high, too far from the compressor 3, in which sufficient heating and evaporation of the condensate is no longer guaranteed.
- compartment 2 If a different model of compressor is installed in compartment 2, such as the one in Fig. 6 shown compressor 3 'of greater height, so this is combined with an evaporation tray 4, which carries the pin 41 at a recess 17 a of the upper groove 11 a matching position.
- the height of the compressor 3 ' is so great that it intrinsically blocks the insertion of an evaporation tray 4 into the lower grooves 10b, 11b, the recess 17a on the upper groove 11a and the pin 41 on one with the compressor 3 'to be combined evaporation tray 4' omitted, since after assembly of this compressor anyway only the attachment of the shell 4 'to the upper grooves 10a, 11a is possible.
- the assembly of the shell 4 'in the lower grooves 10, 11, is also in the in Fig. 6 shown case the evaporation tray 4 'provided with the coding pin 41 in a complementary to the recess 17 a of the upper groove 11 a position.
- Fig. 7 shows yet another view of the tray 2 with in high position above the high compressor 3 'mounted evaporation tray 4', wherein the evaporation tray is shown in section. It can clearly be seen here that the shell becomes flatter from its front side 31 towards the rear side 32, so that it can easily be swung out of the compartment 2 without colliding with the compressor 3 '.
- grooves 10a, 10b, 11a, 11b can also be replaced by other types of suspension, and the number of suspensions or the various Levels in which they allow the mounting of an evaporation tray can be greater than two.

Abstract
Description
Kältegeräte mit automatischer Abtaufunktion weisen herkömmlicherweise eine Verdunstungsschale auf, die zusammen mit dem Verdichter in einem offenen Fach des Kältegerätegehäuses untergebracht ist. Die Verdunstungsschale dient dazu, Kondenswasser, das sich an einem am Kühlraum des Kältegeräts angeordneten, Verdampfer niederschlägt, aufzufangen und zu verdampfen.Refrigeration appliances with automatic defrosting function conventionally have an evaporation tray which is accommodated together with the compressor in an open compartment of the refrigeration appliance housing. The evaporation tray serves to trap and evaporate condensation water, which precipitates on a vaporizer arranged on the cooling space of the refrigeration device.
Eine solche Verdunstungsschale muss eine ausreichende Leistung aufweisen, um unter beliebigen Betriebsbedingungen das anfallende Kondenswasser zu verdunsten, da ein Überlaufen der Schale dazu führen könnte, dass Wasser an spannungsführende Teile des Verdichters oder seiner Umgebung gelangt. Für die Verdunstungsleistung der Schale sind diverse Parameter von Bedeutung, wie etwa die freie Flüssigkeitsoberfläche in der Schale, ihre Temperatur und eine unbehinderte Luftzirkulation zwischen der Schale und der Umgebung des Kältegerätes.Such an evaporation tray must have sufficient power to evaporate under any operating conditions, the accumulating condensation, as overflow of the shell could cause water reaches live parts of the compressor or its environment. For the evaporation performance of the shell various parameters are important, such as the free liquid surface in the shell, its temperature and an unobstructed air circulation between the shell and the environment of the refrigerator.
Die Verdunstungsschale kann unmittelbar am Verdichter oder an den Wänden eines Faches befestigt sein, welches diese zusammen mit dem Verdichter aufnimmt. Die unmittelbare Anbringung der Verdunstungsschale am Verdichter hat den Vorteil, dass ein wirksamer Wärmeübergang vom Verdichter auf die Schale und damit eine hohe Wassertemperatur und eine dementsprechend hohe Verdunstungsleistung erreichbar sind. Ein Nachteil dieser Konstruktion ist jedoch, dass für jeden Verdichtertyp eine passende Verdunstungsschale eigens konstruiert und gefertigt werden muss und der Verdichter nur mit der speziell für ihn passenden Schale in ein Kältegerät eingebaut werden kann. Bei der Serienfertigung von Kältegeräten wäre es jedoch wünschenswert Verdichter unterschiedlicher Hersteller oder Fabrikate, die sich in ihrer Gehäuseform unterscheiden können, in Verbindung mit einem gleichen Modell von Verdunstungsschale einbauen zu können. Außerdem kann die Notwendigkeit, Verdichter und Verdunstungsschale vor ihrem Einbau in ein Kältegerät zusammenfügen, die Montage des Kältegerätes erschweren, weil die Verdunstungsschale den Zugriff auf Befestigungselemente versperrt oder behindert.The evaporation tray may be mounted directly on the compressor or on the walls of a compartment which receives it together with the compressor. The immediate attachment of the evaporation tray on the compressor has the advantage that an efficient heat transfer from the compressor to the shell and thus a high water temperature and a correspondingly high evaporation performance can be achieved. A disadvantage of this design, however, is that for each type of compressor a suitable evaporation tray must be specially designed and manufactured and the compressor can be installed only with the specially suitable for him shell in a refrigerator. In the mass production of refrigerators, however, it would be desirable compressors of different manufacturers or makes that can differ in their housing form, to be able to install in conjunction with a same model of evaporation tray. In addition, the need to assemble compressors and evaporation tray prior to their installation in a refrigeration device, complicate the installation of the refrigerator because the evaporation tray blocks access to fasteners or hindered.
Diese Probleme lassen sich zwar vermeiden, wenn die Verdunstungsschale in dem Fach unabhängig vom Verdichter befestigt wird; es müssen dann aber andere Nachteile in Kauf genommen werden. Da die Temperatur in der Schale und somit ihre Verdunstungsleistung vom Abstand der Schale zum Verdichter abhängig ist, kann sich die Verdunstungsleistung einer Schale als unzureichend erweisen, wenn sie anstatt mit dem Verdichter, für den sie ursprünglich konstruiert wurde, mit einem Verdichter mit geringerer Bauhöhe eingesetzt wird, auch wenn dieser die gleiche Wärmeleistung liefert. Im Endeffekt erlaubt es daher auch die vom Verdichter unabhängige Befestigung der Verdunstungsschale nicht, ein einheitliches Modell von Verdunstungsschalen in Kombination mit unterschiedlichen Verdichtermodellen einzusetzen.Although these problems can be avoided if the evaporation tray is mounted in the compartment independent of the compressor; but then other disadvantages must be accepted. Since the temperature in the shell, and thus its evaporation performance, depends on the distance of the shell to the compressor, the evaporation performance of a shell may prove inadequate if used with a compressor of lesser height, rather than the compressor for which it was originally designed is, even if this provides the same heat output. As a result, it also does not allow the evaporation tray independent of the compressor to employ a uniform model of evaporation cups in combination with different compressor models.
Dokument
Aufgabe der vorliegenden Erfindung ist, ein Kältegerät anzugeben, das die Verwendung von gleichgeformten Verdunstungsschalen in Verbindung mit unterschiedlichen Verdichtermodellen erlaubt.The object of the present invention is to provide a refrigeration device which allows the use of gleichformformten evaporation trays in conjunction with different compressor models.
Die Aufgabe wird gelöst durch ein Kältegerät mit den Merkmalen des Anspruchs 1.The object is achieved by a refrigeration device having the features of claim 1.
In dem in dem Verdichterfach des Kältegeräts Halterungen für die Verdunstungsschale in unterschiedlichen Höhen vorgesehen werden, ist es möglich, die Einbauhöhe der Verdunstungsschale jeweils an die Höhe des mit ihr kombinierten Verdichters anzupassen und so den Abstand zwischen Verdichter und Verdunstungsschale unabhängig vom verwendeten Verdichtermodell so weit einheitlich zu halten, dass eine ausreichende Verdunstungsleistung erzielt wird.In which are provided in the compressor compartment of the refrigerator supports for the evaporation tray at different heights, it is possible to adjust the installation height of the evaporation tray in each case to the height of the compressor combined with it, and so the distance between the compressor and evaporation tray regardless of the compressor model used so far uniform to keep that sufficient evaporation performance is achieved.
Vorzugsweise weisen die Halterungen jeweils Tragoberflächen auf, auf denen seitliche Stege der Verdunstungsschale ruhen.Preferably, the brackets each have supporting surfaces on which rest side webs of the evaporation tray.
Um eine versehentliche Montage der Verdunstungsschale in einer ungeeigneten Höhe zu verhindern, ist den Halterungen jeweils eine Codierung zugeordnet, die die Montage der mit einer komplementären Codierung versehenen Verdunstungsschale nur an jeweils einer dieser Halterungen erlaubt.In order to prevent accidental mounting of the evaporation tray in an inappropriate height, the holders each have a coding associated with it, which allows the mounting of the provided with a complementary coding evaporation tray only on each one of these brackets.
Wenn es sich bei der Codierung der Verdunstungsschale um eine Vertiefung handelt und bei der der Halterung um einen Vorsprung, der in die Vertiefung eingreift, so ist an der zuunterst gelegenen Halterung eine solche Codierung verzichtbar, da eine Verdunstungsschale an dieser Halterung ohnehin nur dann montierbar ist, wenn von mehreren verschiedenen in dem Kältegerät montierbaren Verdichtermodellen das Modell mit der minimalen Bauhöhe eingebaut ist. Damit ist eine irrtümliche Montage der Schale an der untersten Halterung in Verbindung mit einem falschen Verdichtermodell per se ausgeschlossen. Die versehentliche Montage der Verdunstungsschale an einer zu hoch gelegenen Halterung bei Verwendung eines Verdichters mit niedriger Bauhöhe wird jedoch durch die Codierung verhindertIf the coding of the evaporation tray is a recess and in which the holder around a projection which engages in the recess, so on located at the bottom bracket such a coding dispensable, since an evaporation tray on this holder is anyway only mountable when installed by several different in the refrigerator mountable compressor models, the model with the minimum height. Thus, an erroneous assembly of the shell at the bottom bracket in conjunction with a false compressor model per se is excluded. However, the accidental mounting of the evaporation tray on a too high mount when using a compressor with low height is prevented by the coding
Wenn hingegen die Codierung der Schale ein Vorsprung und die der Halterung eine Vertiefung ist, in die der Vorsprung eingreift, so kann aus analogem Grund eine Codierung der obersten Halterung fortgelassen werden.If, however, the coding of the shell is a projection and that of the holder is a recess in which engages the projection, it can be omitted for an analogous reason, a coding of the top bracket.
Die Montage der Verdunstungsschale kann z.B. erfolgen, in dem diese in Art einer Schublade mit ihren Stegen auf eine Halterung aufgesetzt und dann in das Fach eingeschoben wird. Bevorzugt ist jedoch, dass die Verdunstungsschale durch Schwenken um eine vertikale Achse gegen ihre montierte Stellung bringbar bzw. aus dieser Stellung entnehmbar ist. Dies hat den Vorteil, dass ein Verkanten und Steckenbleiben der Schale bei der Montage nicht möglich ist.The mounting of the evaporation tray can e.g. take place in which this is placed in the manner of a drawer with their webs on a holder and then inserted into the compartment. However, it is preferred that the evaporation tray can be brought by pivoting about a vertical axis against its mounted position or removed from this position. This has the advantage that jamming and sticking of the shell during assembly is not possible.
Vorzugsweise kreuzt diese Achse einen der Stege der Verdunstungsschale.Preferably, this axis crosses one of the webs of the evaporation tray.
Dies und die Schwenkbeweglichkeit der Schale erlaubt es, die Codierung an dem von der Achse gekreuzten seitlichen Steg anzubringen. Dies hat den Vorteil, dass die Codierung an einer Stelle angebracht sein kann, die nahe an der offenen Seite des Faches liegt und während der Montage der Schale sichtbar bleibt. Wenn eine ungeübte Person versehentlich versucht, die Schale in einer falschen Halterung zu montieren, und ihr dies nicht gelingt, so kann sie den Grund dafür leicht erkennen und die richtige Halterung wählen.This, and the pivoting mobility of the shell, allows the coding to be applied to the lateral web which is crossed by the axle. This has the advantage that the coding can be located at a location close to the open side of the tray and remains visible during assembly of the tray. If an inexperienced person inadvertently tries to mount the tray in a wrong fixture and fails to do so, they can easily identify the reason and choose the correct fixture.
Um die Sichtbarkeit der Codierung für eine die Schale montierende Person zu verbessern, ist es ferner günstig, wenn die Codierung der Verdunstungsschale durch wenigstens einen von dem Steg nach oben gerichteten Vorsprung gebildet ist, der in montiertem Zustand in eine komplementäre Aussparung an einer Seitenwand des Fachs eingreift.In order to improve the visibility of the coding for a shell-mounting person, it is further favorable if the coding of the evaporation shell is formed by at least one projection which faces upwards from the web and which is in assembled state engages in a complementary recess on a side wall of the compartment.
Diese Codierung ist vorzugsweise durch einen zweiteilig mit der Verdunstungsschale ausgebildeten Körper gebildet, der in einer Mehrzahl von Positionen an der Verdunstungsschale befestigbar ist. Dies erlaubt es, Verdunstungsschalen mit einer gleichen, für verschiedene Verdichtermodelle geeigneten Gestalt in großen Stückzahlen zu fertigen und durch Anbringen der Codierung erst dann für ein bestimmtes Modell von Verdichter spezifisch anzupassen, wenn feststeht, welches Modell tatsächlich eingebaut werden soll.This coding is preferably formed by a body formed in two parts with the evaporation shell, which can be fastened in a plurality of positions on the evaporation shell. This makes it possible to produce evaporation trays with a same shape suitable for different compressor models in large numbers and by attaching the coding only for a specific model of compressor specific adapt when it is clear which model is actually to be installed.
Um zu verhindern, dass aus dem Betrieb des Verdichters resultierende Erschütterungen zu einem Klappern oder einer unerwünschten Wanderbewegung der Verdunstungsschale führen, sind vorzugsweise Rastmittel zum Verrasten der Verdunstungsschale in montierter Position vorgesehen. Bei einer mit seitlichen Stegen ausgestatteten, schwenkbaren Verdunstungsschalen kann ein solches Rastmittel durch eine an dem von der Drehachse abgewandten Steg angebrachte Rastklammer gebildet sein.In order to prevent vibrations resulting from the operation of the compressor resulting in rattling or undesired migration of the evaporation tray, locking means are preferably provided for locking the evaporation tray in the mounted position. In a swivel-type evaporation shells equipped with lateral webs, such a locking means can be formed by a locking clip attached to the web remote from the axis of rotation.
Zum Verhindern von Klappern ist es ferner wünschenswert, dass eine Druckfeder zwischen der Verdunstungsschale und einer Rückwand des Fachs angeordnet ist. Vorzugsweise ist diese Druckfeder eine einteilig mit der Verdunstungsschale gebildete Blattfeder.To prevent rattling, it is further desirable that a compression spring is disposed between the evaporation tray and a rear wall of the tray. Preferably, this compression spring is a leaf spring formed integrally with the evaporation tray.

Die
Von den Rillen 11a, 11 b der zur Außenseite des Gehäuses 1 hin liegenden Seitenwand 9 ist jeweils durch eine vertikale Rippe 15 an ihren der offenen Rückseite zugewandten Ende eine kurze Aussparung 16 abgetrennt. An der Oberseite jeder Rille 11 a, 11 b ist in unterschiedlichen Abständen von der Rippe 15 jeweils eine Vertiefung 17a, 17b gebildet. Die Vertiefung 17a bzw. 17b hat die Funktion einer Codierung für die Montage der Verdunstungsschale 4, wie später noch deutlicher wird.Of the
Die Becken 23 bis 27 sind miteinander jeweils durch Ausschnitte 29 in den Trennwänden 19, 20 verbunden, so dass, wenn die Verdunstungskapazität eines Beckens nicht ausreicht, das jeweils folgende geflutet wird und so die Verdunstungsoberfläche erhöht wird. Ein Überlaufstutzen 30 im letzten Becken 27 ermöglicht im Notfall einen kontrollierten Ablauf von Kondenswasser aus dem Kältegerät heraus, ohne Gefährdung spannungsführender Teile im Fach 2.The basins 23 to 27 are connected to each other by
Die Verdunstungsschale 4 hat einen angenähert trapezförmigen Grundriss, mit einer der offenen Seite des Fachs 2 zugewandten Vorderseite 31, einer dazu in etwa parallelen Rückseite 32, die kürzer als die Vorderseite 31 ist, einer zu Vorderseite 31 und Rückseite 32 senkrechten, der Seitenwand 9 zugewandten Seitenflanke 33 und einer schräg und teilweise gerundet verlaufenden, der Seitenwand 8 zugewandten Seitenflanke 34. Entlang der zwei Seitenflanken 33, 34 sind horizontale Stege 35, 36 an die Schale 4 angeformt, die im montierten Zustand der Schale 4 auf den Unterseiten der Rillen 10, 11 a oder 10b, 11 b ruhen.The
Vom vorderen Ende des Stegs 35 ist durch einen Einschnitt 39 ein kurzer Zapfen 40 abgeteilt. Der Zapfen 40 ist vorgesehen, um bei der Montage der Verdunstungsschale 4 schräg von der Seite kommend in eine der Aussparungen 16 eingeführt zu werden. Bei der weiteren Montage definiert der Eingriff zwischen Zapfen 40 und Aussparung 16 eine vertikale Schwenkachse, um die Verdunstungsschale 4 geschwenkt werden kann, um weiter in das Fach 2 eingeführt zu werden.From the front end of the
Der Steg 36 trägt an seinem vorderen Ende eine Rastklammer, die, wenn die Verdunstungsschale 4 korrekt eingeführt ist, in einen der Durchbrüche 14 der Zunge 13 einrastet. Bei einem Versuch, die Verdunstungsschale 4 in der falschen Höhe zu montieren, stößt der Stift 41 gegen die Seitenwand 9, bevor eine solche Verrastung möglich ist und blockiert so die weitere Einführung der Schale 4 in das Fach 2.The
Eine an die Rückseite 32 der Schale 4 einstückig angeformte Blattfeder 38 drückt im verrasteten Zustand der Verdunstungsschale 4 gegen die Rückwand 12 des Fachs 2 und hält so die Schale 4 unter Spannung, so dass vom Verdichter 3 im Betrieb ausgehende Erschütterungen nicht zu einem Klappern der Schale 4 führen können.A integrally formed on the
Wenn in das Fach 2 ein anderes Modell eines Verdichters eingebaut ist, wie etwa der in
Wenn die Bauhöhe des Verdichters 3' so groß ist, dass dieser von sich aus das Einführen einer Verdunstungsschale 4 in die unteren Rillen 10b, 11 b blockiert, so könnten die Vertiefung 17a an der oberen Rille 11a und der Stift 41 an einer mit dem Verdichter 3' zu kombinierenden Verdunstungsschale 4' entfallen, da nach Montage dieses Verdichters ohnehin nur die Anbringung der Schale 4' an den oberen Rillen 10a, 11a möglich ist. Es kann aber auch wünschenswert sein, einen zu engen Kontakt zwischen der Verdunstungsschale 4' und dem Verdichter 3'auszuschließen, so etwa, wenn dieser Oberflächenabschnitte aufweist, die bei direktem Kontakt die Schale 4' zu stark erhitzen und z.B. zu einer Beschädigung oder vorzeitigen Alterung ihres Kunststoffmaterials führen könnten. Um in einem solchen Fall die Montage der Schale 4' in den unteren Rillen 10, 11 auszuschließen, ist auch im in
Selbstverständlich können die Rillen 10a, 1 0b, 11a, 11b auch durch andere Arten von Aufhängung ersetzt werden, und die Anzahl der Aufhängungen bzw. der verschiedenen Niveaus, in denen sie die Montage einer Verdunstungsschale zulassen, kann größer als zwei sein.Of course, the
