Abstract

A compressor housing comprising an upper shell and a lower shell assembled at a peripheral weld seam. At least one shell extends from the center of the housing beyond the weld seam outwards and upwards.

Description

Die vorliegende Erfindung betrifft ein Kältemittel-Verdichtergehäuse, insbesondere für einen Verdichter zur Verwendung in einem Haushaltskältegerät. Ein solches Verdichtergehäuse ist zum Beispiel aus DE 20 209 839 U1 bekannt. Ein weiteres Verdichtergehäuse gemäß dem Oberbegriff von Anspruch 1 ist aus DE19802453 bekannt.The present invention relates to a refrigerant compressor casing, in particular for a compressor for use in a household refrigerator. Such a compressor housing is made, for example DE 20 209 839 U1 known. Another compressor housing according to the preamble of claim 1 is made DE19802453 known.

Das herkömmliche Verdichtergehäuse ist zusammengesetzt aus zwei Schalenteilen, die miteinander hermetisch verschweißt sind und den Verdichter umschließen. Einerseits zum Kühlen des Verdichters, andererseits zur Beseitigung von Kondenswasser, das im Inneren des Kältegerätes in Normalbetrieb regelmäßig anfällt, ist an der oberen Schale des Gehäuses ein Verdunstungsbehälter montiert, in welchen das Kondenswasser hineingeleitet wird und in dem es mit Hilfe der Abwärme des Verdichters verdampft wird.The conventional compressor housing is composed of two shell parts, which are hermetically welded together and enclose the compressor. On the one hand to cool the compressor, on the other hand to eliminate condensation that accumulates regularly in the interior of the refrigerator in normal operation, an evaporation tank is mounted on the upper shell of the housing, in which the condensed water is introduced and in which it evaporates with the aid of the waste heat of the compressor becomes.

Nur wenn sich der Boden des Kondenswasserbehälters sehr eng an die gewölbte Oberseite der oberen Gehäuseschale anschmiegt, ist ein effizienter Wärmeübergang von der Gehäuseschale in das Kondenswasser und damit eine effiziente Kühlung des Verdichters und Verdunstung des Kondenswassers möglich. Um einen engen Formschluss zu gewährleisten, müssen der Boden des Kondenswasserbehälters und die obere Gehäuseschale mit engen Toleranzen gefertigt werden, was mit Kosten verbunden ist.Only when the bottom of the condensed water container fits snugly against the curved top side of the upper housing shell, an efficient heat transfer from the housing shell into the condensate water and thus an efficient cooling of the compressor and evaporation of the condensed water is possible. To ensure a tight fit, the bottom of the condensate tank and the upper housing shell must be made with tight tolerances, which is associated with costs.

Aufgabe der Erfindung ist, ein Gehäuse für einen Verdichter anzugeben, das bei minimalen Fertigungskosten und geringen Anforderungen an die Maßgenauigkeit der Schalenteile eine gleichmäßig effiziente und wirksame Kühlung des Verdichters bzw. Verdunstung des Kondenswassers gewährleistet.The object of the invention is to provide a housing for a compressor, which ensures a uniformly efficient and effective cooling of the compressor or evaporation of condensate with minimal production costs and low demands on the dimensional accuracy of the shell parts.

Die Aufgabe wird gelöst durch ein Verdichtergehäuse mit einer oberen und einer unteren Schale, die an einer umlaufenden Nahtstelle miteinander verbunden sind, bei dem wenigstens eine der Schalen in radialer Richtung nach außen sowie nach oben über die Nahtstelle hinausreicht. Aus dieser Formgebung resultiert an der Oberseite des Verdichtergehäuses eine Konkavität, deren Wände unmittelbar durch die Schalen des Verdichtergehäuses gebildet sind und die in der Lage ist, Kondenswasser aufzunehmen. Der Fortfall der herkömmlichen Verdunstungsschale als eigenes Bauteil und der unmittelbare Kontakt des Kondenswassers mit den Schalen des Verdichtergehäuses gewährleistet eine effiziente Wärmeübertragung an das Kondenswasser unabhängig von eventuellen Fertigungsstreuungen in der Form der Schalen, und damit eine effiziente Kühlung und Verdunstung.The object is achieved by a compressor housing having an upper and a lower shell, which are connected to one another at a peripheral seam, in which at least one of the shells extends in the radial direction outwards and upwards beyond the seam. From this shape results at the top of the compressor housing, a concavity whose walls are formed directly by the shells of the compressor housing and which is able to absorb condensation. The omission of the conventional evaporation tray as a separate component and the direct contact of the condensate with the bowls of the compressor housing ensures efficient heat transfer to the condensate, regardless of any manufacturing variations in the shape of the bowls, and thus efficient cooling and evaporation.

Einer ersten Ausgestaltung zufolge ist es die untere Schale, die über die Nahtstelle hinausreicht und an dieser mit einem äußeren Rand der oberen Schale verbunden ist, so dass die Wände der entstehenden Konkavität zum Teil durch die obere Schale und zum Teil durch über die Nahtstelle hinausreichende Teile der unteren Schale gebildet sind.According to a first embodiment, it is the lower shell, which extends beyond the seam and is connected thereto with an outer edge of the upper shell, so that the walls of the resulting concavity partly through the upper shell and partly through reaching beyond the seam parts the lower shell are formed.

Einer zweiten Ausgestaltung zufolge ist es die obere Schale, die über die Nahtstelle hinausreicht und an der Nahtstelle mit einem äußeren Rand der unteren Schale verbunden ist. In diesem Fall begrenzt die obere Schale allein die Konkavität.According to a second embodiment, it is the upper shell, which extends beyond the seam and is connected at the seam to an outer edge of the lower shell. In this case, the upper shell alone limits the concavity.

Vorzugsweise bildet die Nahtstelle eine tiefste Stelle einer umlaufenden, nach oben offenen Rinne.Preferably, the seam forms a lowest point of a circumferential, upwardly open channel.

Bei unterschiedlichen Schalenhöhen, insbesondere bei einer gegenüber der oberen Schale höheren unteren Schale, lassen sich die Verdichter besonders gut vormontieren.At different shell heights, in particular at a higher lower shell compared to the upper shell, the compressors can be pre-assembled particularly well.

Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachfolgenden Beschreibung von Ausführungsbeispielen anhand der beigefügten Figuren. Es zeigen:

Further features and advantages of the invention will become apparent from the following description of embodiments with reference to the accompanying figures. Show it:
Fig. 1
a schematic section through a compressor housing according to a first embodiment of the invention;
Fig. 2
an enlarged detail Fig. 1 ;
Fig. 3
a schematic section through a second embodiment of the housing; and
Fig. 4
an enlarged detail of one opposite Fig. 3 slightly modified design.

Das in Fig. 1 gezeigte Gehäuse setzt sich zusammen aus einer flachen unteren Schale 1, an deren Außenseite mehrere Befestigungsfüße 2 für die Montage des Verdichtergehäuse in einem Kältegerät angeschweißt sind, und einer oberen Schale 4, die mit dem äußeren Rand der unteren Schale 1 über eine Schweißnaht 3 verbunden ist. Die obere Schale 4 erstreckt im Schnitt von einem zentralen Scheitelpunkt aus nach außen und abwärts bis zur Schweißnaht 3 sowie in radialer Richtung zunächst über die Schweißnaht 3 hinaus weiter nach unten, um schließlich wieder anzusteigen. Die obere Schale 4 bildet so eine nach oben offene umlaufende Rinne 5, die in der Lage ist, zu verdunstendes Kondenswasser aufzunehmen.This in Fig. 1 shown housing is composed of a flat lower shell 1, on the outside of a plurality of mounting feet 2 are welded for mounting the compressor housing in a refrigerator, and an upper shell 4, which is connected to the outer edge of the lower shell 1 via a weld 3 , The upper shell 4 extends in section from a central vertex outwards and downwards to the weld seam 3 and in the radial direction, first on the weld 3 also further down to finally rise again. The upper shell 4 thus forms an upwardly open circumferential groove 5, which is able to absorb condensate to be evaporated.

Der tiefste Punkt 6 der Rinne 5 liegt bei dieser Ausgestaltung in radialer Richtung ein Stück weit außerhalb der Schweißnaht 3, so dass bei niedrigem Wasserstand das Wasser in der Rinne 5 den innerhalb der Schweißnaht 3 liegenden Bereich der oberen Schale 4 nicht berührt und daher nur schwach erwärmt wird. Bei steigendem Wasserstand breitet sich aufgrund des zum Mittelpunkt hin allmählich ansteigenden Verlaufes des inneren Bereiches der Schale 4 das Wasser immer weiter auf diesen inneren Bereich aus, wodurch einerseits die Effektivität der Wärmeübertragung auf das Wasser und andererseits die zur Verfügung stehende Verdunstungsoberfläche stark zunehmen. So steigt mit dem Wasserstand auch die Verdunstungsrate, und ein Überlaufen wird vermieden.The lowest point 6 of the channel 5 is located in this embodiment in the radial direction a little way outside the weld 3, so that at low water level, the water in the channel 5 does not touch the lying within the weld 3 area of the upper shell 4 and therefore only weak is heated. As the water level rises, the water gradually spreads to this inner area due to the gradually increasing towards the center of the inner region of the shell 4, whereby on the one hand the effectiveness of the heat transfer to the water and on the other hand the available evaporation surface increase sharply. Thus, with the water level and the evaporation rate increases, and overflow is avoided.

Wie die Detailvergrößerung der Fig. 2 zeigt, ist in der oberen Schale 4 in Höhe der Schweißnaht 3 eine umlaufende Sicke 7 gebildet, in die der Rand der unteren Schale 1 eingreift. So ist die Position der Schalen 1, 4 zueinander vor dem Verschweißen festgelegt, und es ist leicht sicherzustellen, dass sie sich auf dem gesamten Umfang der unteren Schale 1 berühren und dicht verschweißt werden können.Like the detail enlargement of the Fig. 2 shows, in the upper shell 4 at the level of the weld 3, a circumferential bead 7 is formed, in which the edge of the lower shell 1 engages. Thus, the position of the shells 1, 4 is fixed to each other before welding, and it is easy to ensure that they touch on the entire circumference of the lower shell 1 and can be tightly welded.

Fig. 3 zeigt einen zu Fig. 1 analogen Schnitt durch ein Verdichtergehäuse gemäß einer zweiten Ausgestaltung der Erfindung. Die untere Schale 1 ist hier in Form eines Topfes mit flachem Boden und mit in einem unterem Bereich steil ansteigenden, in einem oberem Bereich auseinanderlaufenden Seitenwänden 8 dargestellt, sie könnte aber auch einen gewölbten Boden wie in Fig. 1 gezeigt haben; entsprechend wäre die Topfform der Fig. 3 auch auf die Ausgestaltung der Fig. 1 übertragbar. Fig. 3 shows you one Fig. 1 analog section through a compressor housing according to a second embodiment of the invention. The lower shell 1 is here shown in the form of a pot with a flat bottom and steeply rising in a lower region, diverging in an upper region side walls 8, but it could also have a curved bottom as in Fig. 1 have shown; Accordingly, the pot shape would be the Fig. 3 also on the design of the Fig. 1 transferable.

Auf dem aufgeweiteten oberen Abschnitt der Seitenwand 8 ruht eine gewölbte obere Schale 4; ihr Rand ist mit der Seitenwand 8 verschweißt. Der oberste Bereich der Seitenwand 8, oberhalb der Schweißnaht 3, begrenzt zusammen mit der oberen Schale 4 eine umlaufende Rinne 5, die Kondenswasser aufnimmt. Aufgrund der gewölbten Form der Schale 4 nimmt auch hier die Fläche, auf der das Wasser in der Rinne 5 direkt durch die obere Schale 4 hindurch beheizt wird, mit steigendem Wasserstand zu, genauso wie die freie Oberfläche des Wassers, an der die Verdunstung stattfindet.On the flared upper portion of the side wall 8 rests a domed upper shell 4; its edge is welded to the side wall 8. The uppermost region of the side wall 8, above the weld seam 3, together with the upper shell 4, delimits a circumferential groove 5, which absorbs condensation water. Due to the curved shape of the shell 4, the surface on which the water in the channel 5 is heated directly through the upper shell 4 also increases with increasing water level, as does the free surface of the water at which the evaporation takes place.

Bei dieser Ausgestaltung fallen die Schweißnaht 3 und die tiefste Stelle 6 der Rinne 5 zusammen, so dass auch bei niedrigem Wasserstand in der Rinne 5 das darin befindliche Wasser unmittelbar durch die obere Schale 4 hindurch erwärmt wird.In this embodiment, the weld 3 and the lowest point 6 of the channel 5 coincide, so that even at low water level in the channel 5, the water therein is heated directly through the upper shell 4 therethrough.

Fig. 4 zeigt in einem vergrößerten Schnitt die Umgebung der Schweißnaht 3 in einer gegenüber Fig. 3 geringfügig abgewandelten Ausgestaltung. Hier ist die Seitenwand 8 der unteren Schale 1 im Wesentlichen vertikal, bis auf eine Schulter 9, die zwei Wandabschnitte von geringfügig unterschiedlichem Durchmesser verbindet und als Auflage dient, an der die obere Schale 4 verschweißt ist. Fig. 4 shows in an enlarged section the environment of the weld 3 in a opposite Fig. 3 slightly modified embodiment. Here, the side wall 8 of the lower shell 1 is substantially vertical, except for a shoulder 9, which connects two wall sections of slightly different diameter and serves as a support on which the upper shell 4 is welded.
