Description

Verdichter-Verdunstungsschale-Anordnung für ein Kältegerät Compressor evaporation bowl arrangement for a refrigeration device
Die vorliegende Erfindung betrifft eine Anordnung mit einem Verdichter und einer Verdunstungsschale für ein Kältegerät wie etwa einen Kühl- oder Gefrierschrank.The present invention relates to an arrangement with a compressor and an evaporation tray for a refrigerator, such as a refrigerator or freezer.
Bei einem Kühlschrank kondensiert vom Kühlgut an die Luft im Innenraum des Kühlschranks abgegebene Feuchtigkeit oder durch Türöffnen eingetragene Feuchtigkeit am Verdampfer. Diese Feuchtigkeit muss aus dem Innenraum des Kühlschranks abgeführt werden. Zu diesem Zweck ist im Allgemeinen an einer Wand des Innenraums unterhalb des Verdampfers eine Sammelrinne angebracht, die vom Verdampfer abfließende Feuchtigkeit auffängt. Vom tiefsten Punkt der Sammelrinne aus ist durch die Gehäusewand des Kühlschranks ein Kanal geführt, durch den das Wasser aus dem Innenraum abfließen kann. Dieser Kanal mündet herkömmlicherweise in einer offenen Schale, in der das Wasser verdunsten kann. Die Schale ist über dem Verdichter des Kühlschranks angeordnet, um das Wasser mit der Abwärme des Verdichters zu erwärmen und dadurch seine Verdunstung zu beschleunigen.In the case of a refrigerator, moisture released from the refrigerated goods condenses into the air in the interior of the refrigerator or moisture entered on the evaporator by opening the door. This moisture must be removed from the interior of the refrigerator. For this purpose, a collecting channel is generally attached to a wall of the interior space below the evaporator, which collects moisture flowing away from the evaporator. From the lowest point of the collecting trough, a channel is led through the housing wall of the refrigerator through which the water can flow out of the interior. This channel traditionally ends in an open bowl in which the water can evaporate. The bowl is placed over the compressor of the refrigerator to heat the water with the waste heat from the compressor, thereby accelerating its evaporation.
Auch bei Gefriergeräten mit Abtauautomatik, sogenannten No-Frost-Geräten, bei denen der Verdampfer von Zeit zu Zeit künstlich aufgeheizt wird, um daran niedergeschlagenen Reif abzutauen, kommen solche Verdunstungsschalen zum Einsatz.Such evaporation trays are also used in freezers with automatic defrost, so-called no-frost devices, in which the evaporator is artificially heated from time to time in order to defrost the frost deposited on it.
Eine solche Schale muss möglichst nah am Verdichter angebracht sein, um eine ausreichende Erwärmung zu erzielen, die gewährleistet, dass die Schale im Betrieb nicht überläuft und Wasser auf den Verdichter fließt. Um eine solche enge und bei Serienfertigung von Gerät zu Gerät einheitliche Nachbarschaft zwischen Verdichter und Verdunstungsschale zu erreichen, wird die Schale im Allgemeinen nicht an Gehäuseteilen des Kältegeräts montiert, sondern unmittelbar an dem Verdichter.Such a bowl must be placed as close as possible to the compressor in order to achieve sufficient heating, which ensures that the bowl does not overflow during operation and water flows onto the compressor. In order to achieve such a close neighborhood between compressor and evaporation tray, which is uniform in series production from device to device, the tray is generally not mounted on housing parts of the refrigeration device, but rather directly on the compressor.
Eine bekannte Möglichkeit, die Schale zu montieren ist das Verrasten an Rohrstutzen des Verdichters. Dies ist jedoch unter dem Gesichtspunkt einer festen und sicherenA known way to mount the shell is to snap it onto the pipe socket of the compressor. However, this is from the standpoint of a firm and secure
Anbringung der Verdunstungsschale unbefriedigend, da maximal zwei Befestigungspunke an Ein- und Ausgangsleitung des Verdichters zur Verfügung stehen und der Abstand zwischen den Rohrstutzen und der Verdunstungsschale groß sein kann.Attachment of the evaporation tray unsatisfactory, since a maximum of two fastening points are available on the inlet and outlet lines of the compressor and the distance between the pipe socket and the evaporation tray can be large.
Die von der Anmelderin gegenwärtig eingesetzte Technik nutzt daher Flachstifte, die auf die Oberseite des Verdichters geschweißt werden, um daran die Verdunstungsschale zu montieren. Mit dieser Technik kann die Verdunstungsschale zwar fest und sicher sowie mit einer reproduzierbaren Position in Bezug auf den Verdichter montiert werden, sie hat jedoch den Nachteil, dass das Schweißen arbeitsaufwändig ist, weil die zum Anbringen der Stifte vorgesehenen Stellen am Verdichtergehäuse zuvor blankgeschliffen werden müssen, und dass bei unachtsamem Schweißen Beschädigungen des Verdichtergehäuses nicht ausgeschlossen sind. Wenn beim Schweißen das Gehäuse des Verdichters ein Loch bekommt, so ist dieser Schaden nicht wirtschaftlich zu beheben, und der Verdichter muss verschrottet werden.The technology currently used by the applicant therefore uses flat pins which are welded onto the top of the compressor in order to mount the evaporation tray thereon. With this technique, the evaporation tray can be installed securely and securely and with a reproducible position in relation to the compressor, but it has the disadvantage that welding is labor-intensive, because the locations provided for attaching the pins on the compressor housing have to be polished beforehand, and that damage to the compressor housing cannot be ruled out in the event of careless welding. If there is a hole in the compressor housing during welding, this damage cannot be repaired economically and the compressor must be scrapped.
Aufgabe der vorliegenden Erfindung ist, eine Verdichter-Verdunstungsschale-Anordnung anzugeben, die einfach und wirtschaftlich realisierbar ist.The object of the present invention is to provide a compressor-evaporation tray arrangement which is simple and economically feasible.
Die Aufgabe wird gelöst durch eine Anordnung mit den Merkmalen des Anspruchs 1.The object is achieved by an arrangement with the features of claim 1.
Die Rastflanken der oberen Halbschale können mit geringem Aufwand bereits bei der Fertigung der Schale, noch vor dem Zusammenbau des Verdichters, eingearbeitet werden. Der Zusammenbau der erfindungsgemäßen Anordnung kann daher in einfacher Weise erfolgen, in dem die Schale einfach auf den Verdichter bis zum Verrasten aufgepresst wird, oder durch Aufsetzen und anschließendes Verdrehen in Art einer Bajonettbefestigung.The latching flanks of the upper half-shell can be incorporated with little effort during the manufacture of the shell, even before the compressor is assembled. The assembly of the arrangement according to the invention can therefore be carried out in a simple manner by simply pressing the shell onto the compressor until it snaps into place, or by fitting and then rotating it in the manner of a bayonet attachment.
Um den Zusammenbau zu vereinfachen, ist es wünschenswert, dass die obere Halbschale eine um eine Achse rotationssymmetrische Grundform aufweist, und dass die Rastflanken in einer gleichen Höhe in Bezug auf diese Achse angeordnet sind. So ist es möglich, die Verdunstungsschale in einer Vielzahl von Orientierungen entsprechend dem Symmetriegrad zu montieren; das Suchen einer zum Montieren geeigneten Orientierung der Schale wird dadurch erleichtert oder vollends überflüssig. Die Rastflanken können an wenigstens einem Vorsprung oder wenigstens einer Rille der oberen Halbschale gebildet sein. Dabei kann es sich insbesondere um einen einzigen, umlaufenden Vorsprung oder um mehrere, voneinander getrennte und in regelmäßigen Winkelabständen um den Umfang der Halbschale verteilte Vorsprünge handeln; entsprechend kann auch die Rille sich um den gesamten Umfang der Halbschale erstrecken, oder mehrere Rillen erstrecken sich in einer Ebene, über getrennte Umfangsabschnitte der Halbschale.In order to simplify the assembly, it is desirable that the upper half-shell has a basic shape that is rotationally symmetrical about an axis, and that the latching flanks are arranged at the same height with respect to this axis. So it is possible to mount the evaporation tray in a variety of orientations according to the degree of symmetry; the search for an orientation of the shell suitable for mounting is thereby made easier or completely unnecessary. The locking flanks can be formed on at least one projection or at least one groove of the upper half-shell. This can be, in particular, a single, circumferential projection or a plurality of projections which are separate from one another and distributed at regular angular intervals around the circumference of the half-shell; Accordingly, the groove can also extend around the entire circumference of the half-shell, or a plurality of grooves extend in one plane, over separate circumferential sections of the half-shell.
Die Halteklauen sind vorzugsweise flexibel, so dass sie beim Aufstecken der Verdunstungsschale auf die obere Halbschale auseinandergespreizt werden, um anschließend hinter die Rastflanken eingreifen zu können.The holding claws are preferably flexible, so that they are spread apart when the evaporation tray is placed on the upper half-tray, so that it can then engage behind the locking flanks.
Es k ann a uch w ünschenswert s ein, s tarre H alteklauen v erwenden z u können, s o e twa wenn die Verdunstungsschale aus einem steifen Material geformt ist und die Halteklauen einteilig mit der Schale sein sollen. In diesem Fall ist eine Verrastung der Verdunstungsschale auf einfache Weise erreichbar, wenn die Vorsprünge in Umfangsrichtung der oberen Halbschale durch Zwischenräume getrennt sind, deren Breite wenigstens der Breite der Halteklauen entspricht, so dass diese beim Aufsetzen der Verdunstungsschale auf den Verdampfer zwischen den Vorsprüngen durchgeführt und durch anschließendes Verdrehen an diesen zum Eingriff gebracht werden können.It may also be desirable to be able to use rigid claws, for example if the evaporation bowl is made of a rigid material and the holding claws are to be made in one piece with the bowl. In this case, the evaporation tray can be locked in a simple manner if the projections in the circumferential direction of the upper half-tray are separated by gaps, the width of which corresponds at least to the width of the holding claws, so that these are carried out between the projections when the evaporation tray is placed on the evaporator and can be brought into engagement by subsequent twisting.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen mit Bezug auf die beigefügten Figuren. Es zeigen:Further features and advantages of the invention result from the following description of exemplary embodiments with reference to the attached figures. Show it:

Fig. 2 eine perspektivische Ansicht der vollständigen Verdunstungsschale aus Fig. 1 ; undFIG. 2 is a perspective view of the complete evaporation tray from FIG. 1; and
Fig. 3 einen Schnitt durch das Oberteil eines Verdichters mit darauf montierter Verdunstungsschale gemäß einer zweiten Ausgestaltung der Erfindung. Fig. 1 zeigt eine perspektivische Ansicht des Oberteils des Gehäuses 1 eines Verdichters für ein Kältegerät sowie, halbiert, einer darauf montierten Verdunstungsschale 2. Eine obere Halbschale 1 und eine nur zum Teil dargestellte untere Halbschale 9 sind durch eine Schweißnaht 10 verbunden. Die untere Halbschale 9 trägt vier Befestigungslaschen 11 zum Verschrauben des Verdichters in einem Kältegerät, von denen in der Fig. nur eine zu sehen ist. Die Halbschale 1 ist eine runde Kuppel, die aus Blech einteilig durch Tiefziehen geformt ist. Aus der Kuppelform sind drei rippenförmige Vorsprünge 3 herausgearbeitet, die sich in einer gleichen zur vertikalen Symmetrieachse der Kuppel senkrechten Ebene jeweils über einen Winkel von 60° erstrecken.Fig. 3 shows a section through the upper part of a compressor with an evaporation tray mounted thereon according to a second embodiment of the invention. 1 shows a perspective view of the upper part of the housing 1 of a compressor for a refrigeration device and, halved, an evaporation shell 2 mounted thereon. An upper half shell 1 and a lower half shell 9 only shown in part are connected by a weld 10. The lower half-shell 9 carries four fastening tabs 11 for screwing the compressor in a refrigerator, of which only one can be seen in the figure. The half-shell 1 is a round dome which is formed in one piece from sheet metal by deep drawing. Three rib-shaped projections 3 are worked out of the dome shape, each of which extends over an angle of 60 ° in a plane perpendicular to the vertical axis of symmetry of the dome.
Die in Fig. 2 vollständig gezeigte Verdunstungsschale 2 hat einen Boden 4, der der Kuppelform der oberen Halbschale 1 angepasst ist. Am Rand des Bodens 4, dort wo dieser mit der Seitenwand der Verdunstungsschale 2 zusammentrifft, sind drei Halteklauen 5 angeordnet. Diese erstrecken sich jeweils ebenfalls über einen Winkel von knapp 60° und sind gleichmäßig über den Umfang der Verdunstungsschale 2 verteilt. So ist es möglich, die Verdunstungsschale 2 zu montieren, in dem sie zunächst in einer Orientierung auf die Halbschale 1 aufgesetzt wird, in der die Halteklauen 5 die Zwischenräume zwischen benachbarten Rippen 3 durchgreifen und anschließend die Verdunstungsschale 2 zu d rehen, so d ass d ie Halteklauen 5 mit Rastflanken 7 a n d er Unterseite der Rippen 3 in Kontakt kommen und so die Verdunstungsschale 2 gegen die obere Halbschale 1 gedrückt halten.The evaporation shell 2 shown completely in FIG. 2 has a bottom 4 which is adapted to the dome shape of the upper half shell 1. At the edge of the bottom 4, where it meets the side wall of the evaporation tray 2, three holding claws 5 are arranged. These also each extend over an angle of almost 60 ° and are evenly distributed over the circumference of the evaporation tray 2. So it is possible to mount the evaporation tray 2 by first placing it on the half-shell 1 in an orientation in which the holding claws 5 reach through the spaces between adjacent ribs 3 and then rotate the evaporation tray 2 so that the d ie the holding claws 5 come into contact with the locking flanks 7 on the underside of the ribs 3 and so hold the evaporation tray 2 against the upper half-tray 1.
Die Verdunstungsschale 2 nach diesem Ausführungsbeispiel kann einteilig aus einem steifen Material gefertigt sein, da die Montage keine wesentliche Verformung der Halteklauen 5 erfordert.The evaporation tray 2 according to this embodiment can be made in one piece from a rigid material, since the assembly does not require any significant deformation of the holding claws 5.
Bei einer alternativen Ausgestaltung sind die drei Rippen 3 durch eine sich über den gesamten Umfang der Halbschale 1 erstreckenden Rippe ersetzt. In diesem Falle müssen die Halteklauen der Verdunstungsschale flexibel sein, damit die Verdunstungsschale durch Aufstecken auf die durchgehende Rippe montiert werden kann, wobei die Halteklauen nach außen gebogen werden. Zu diesem Zweck kann die gesamte Verdunstungsschale aus einem flexiblen Material geformt sein, oder flexible Halteklauen können an eine ansonsten steife Verdunstungsschale angefügt, z.B. durch Umspritzen angeformt, sein. Wenn das Material der Halteklauen nicht nur flexibel, sondern auch dehnbar ist, so können die Halteklauen auch als ein sich über den gesamten Umfang der Verdunstungsschale 2 erstreckender, geschlossener Ring ausgebildet sein.In an alternative embodiment, the three ribs 3 are replaced by a rib extending over the entire circumference of the half-shell 1. In this case, the holding claws of the evaporation tray have to be flexible so that the evaporation tray can be mounted on the continuous rib, the holding claws being bent outwards. For this purpose, the entire evaporation tray can be formed from a flexible material, or flexible holding claws can be attached to an otherwise rigid evaporation tray, for example molded on by injection molding. If the material of the holding claws is not only flexible but also stretchable, the holding claws can also be designed as a closed ring which extends over the entire circumference of the evaporation shell 2.
Bei der in Fig. 3 im Schnitt gezeigten zweiten Ausgestaltung der erfindungsgemäßen Anordnung ist die Verdunstungsschale an einer umlaufenden Rille 6 befestigt, die in die obere Halbschale 1 eingetieft ist. Die in die Rille 6 eingreifenden Halteklauen 5 können auch hier zu mehreren über den Umfang der Verdunstungsschale 2 verteilt sein, oder sie können einen einzigen geschlossenen Ring bilden.In the second embodiment of the arrangement according to the invention shown in section in FIG. 3, the evaporation shell is fastened to a circumferential groove 6 which is recessed into the upper half shell 1. The claws 5 engaging in the groove 6 can also be distributed here in a plurality over the circumference of the evaporation shell 2, or they can form a single closed ring.
Rastflanken 7 zur Verankerung der Verdunstungsschale sind hier durch die obere Seitenwand der Rille 6 gebildet. Locking flanks 7 for anchoring the evaporation tray are formed here by the upper side wall of the groove 6.
