Description

Die vorliegende Erfindung betrifft ein Kältegerät, insbesondere ein Haushaltskältegerät, mit einer Verdampferkammer und einer die Verdampferkammer entwässernden Kondenswasserableitung.The present invention relates to a refrigeration appliance, in particular a household refrigeration appliance, with an evaporator chamber and a condensation water drain line that drains the evaporator chamber.

Wenn ein in einer Verdampferkammer angeordneter Verdampfer ein von der Verdampferkammer getrenntes Lagerfach kühlt, indem Luft zwischen der Verdampferkammer und dem Lagerfach umgewälzt wird, schlägt sich Feuchtigkeit, die die Luft in dem Lagerfach aufgenommen hat, in der Verdampferkammer überwiegend am Verdampfer selbst, zum Teil aber auch an kalten Wänden der Verdampferkammer in deren stromabwärts vom Verdampfer gelegenen Teil als Reif nieder.When an evaporator located in an evaporator chamber cools a storage compartment separate from the evaporator chamber by circulating air between the evaporator chamber and the storage compartment, moisture that has been absorbed by the air in the storage compartment is reflected in the evaporator chamber mostly on the evaporator itself, but in part also deposited as frost on the cold walls of the evaporator chamber in the part downstream from the evaporator.

Um einen auf Dauer energieeffizienten Betrieb eines solchen Kältegeräts zu gewährleisten, muss dieser Reif von Zeit zu Zeit beseitigt werden. Dazu ist in der Verdampferkammer unter dem Verdampfer eine Wasserablaufschale montiert, in der vom Verdampfer ablaufendes Tauwasser zusammenläuft. Um auch den sich an den kalten Wänden der Verdampferkammer niederschlagenden Reif sicher auffangen zu können, müsste eine solche in der Verdampferkammer montierte Wasserablaufschale sich bis unter die Unterkanten dieser Wände erstrecken, doch dies ist mit der Anforderung, dass die Verdampferkammer sowohl einfach aufgebaut als auch zu Wartungszwecken zerlegbar sein soll, nur schwerlich zu vereinbaren. Herkömmlicherweise hat deshalb die Wasserablaufschale eine Stirnwand, die einer stromabwärtigen Wand der Verdampferkammer zugewandt ist, sowie Befestigungsvorsprünge, die über die Stirnwand überstehen, durch eine Öffnung der stromabwärtigen Wand hindurchgreifen und an einer von der Verdampferkammer abgewandten Oberfläche der stromabwärtigen Wand verhakt sind. Diese Befestigungsvorsprünge können zwar den Abstand zwischen der Stirnwand der Wasserablaufschale und der stromabwärtigen Wand der Verdampferkammer begrenzen, können ihn aber, bedingt durch Fertigungstoleranzen, nicht exakt zu Null machen. Dies kann dazu führen, dass Tauwasser, das an der stromabwärtigen Wand herabläuft, nicht in die Wasserablaufschale gelangt, sondern zwischen deren Stirnwand und der stromabwärtigen Wand hindurchläuft und dadurch Bereiche des Kältegeräts erreicht, wo ein weiterer Abfluss des Wassers nicht gewährleistet ist und sich ansammelndes Wasser zu Funktionsstörungen des Kältegeräts führen kann.In order to ensure long-term energy-efficient operation of such a refrigeration device, this frost must be removed from time to time. For this purpose, a water drain pan is installed in the evaporator chamber under the evaporator, in which the condensed water that runs off the evaporator collects. In order to be able to safely catch the frost that settles on the cold walls of the evaporator chamber, such a water drainage tray mounted in the evaporator chamber would have to extend below the lower edges of these walls, but this is with the requirement that the evaporator chamber be both simply constructed and Maintenance purposes should be dismantled, difficult to agree. Conventionally, therefore, the water drain pan has an end wall facing a downstream wall of the evaporator chamber, and fastening projections protruding from the end wall, penetrating through an opening of the downstream wall, and hooked to a surface of the downstream wall remote from the evaporator chamber. Although these attachment projections can limit the distance between the front wall of the water drainage tray and the downstream wall of the evaporator chamber, they cannot make it exactly zero due to manufacturing tolerances. This can result in condensation water running down the downstream wall not getting into the water drainage tray, but instead running between its end wall and the downstream wall and thus areas of the refrigeration device reached where further drainage of the water is not guaranteed and accumulating water can lead to malfunctions of the refrigeration device.

DE 10 2006 015994 A1 betrifft ein Kältegerät mit einer Lagerkammer und einer Verdampferkammer, die mit der Lagerkammer über einen Kaltluftdurchgang und einen Warmluftdurchgang kommuniziert und die einen Verdampfer enthält, an welchem aus der Lagerkammer zuströmende Luft abgekühlt und anschließend in die Lagerkammer zurückgeführt wird. DE 10 2006 015994 A1 relates to a refrigerator with a storage chamber and an evaporator chamber which communicates with the storage chamber via a cold air passage and a warm air passage and which contains an evaporator at which air flowing in from the storage chamber is cooled and then returned to the storage chamber.

Aufgabe der Erfindung ist, ein Kältegerät zu schaffen, bei dem die Verdampferkammer einfach und zerlegbar aufgebaut ist und ein vollständiger Abfluss des Tauwassers gewährleistet ist.The object of the invention is to create a refrigeration device in which the evaporator chamber is constructed in a simple and dismountable manner and a complete drainage of the condensation water is ensured.

Die Aufgabe wird gelöst, indem bei einem Kältegerät mit einer Verdampferkammer, einem in der Verdampferkammer montierten Verdampfer, einem Ventilator zum Antreiben eines Luftstroms durch die Verdampferkammer und einer Wasserablaufschale, die in der Verdampferkammer unter dem Verdampfer montiert ist und eine Stirnwand, die einer stromabwärtigen Wand der Verdampferkammer zugewandt ist, sowie wenigstens einen über die Stirnwand überstehenden und durch eine Öffnung der stromabwärtigen Wand hindurchgreifenden Befestigungsvorsprung aufweist, in einer Anschlagstellung, in der eine äußere Oberfläche der Stirnwand eine innere Oberfläche der stromabwärtigen Wand an einem inneren Kontaktpunkt berührt und eine rückwärtige Oberfläche des Befestigungsvorsprungs eine äußere Oberfläche der stromabwärtigen Wand an einem äußeren Kontaktpunkt berührt, zu den einander berührenden Oberflächen an den Kontaktpunkten tangentiale Ebenen vom äußeren Kontaktpunkt zur Öffnung hin konvergieren.The object is achieved in that, in a refrigeration appliance having an evaporator chamber, an evaporator mounted in the evaporator chamber, a fan for driving an air flow through the evaporator chamber and a water drainage tray which is mounted in the evaporator chamber under the evaporator and an end wall which is a downstream wall faces the evaporation chamber, and has at least one fastening projection projecting beyond the end wall and reaching through an opening in the downstream wall, in a stop position in which an outer surface of the end wall touches an inner surface of the downstream wall at an inner contact point and a rear surface of the attachment projection contacts an outer surface of the downstream wall at an outer contact point, planes tangent to the contacting surfaces at the contact points converge from the outer contact point towards the opening.

Durch die Konvergenz der tangentialen Ebenen ist es auch trotz gewisser Abmessungstoleranzen der Verdampferkammer und der Wasserablaufschale möglich, einen eng anliegenden Kontakt zwischen der Stirnwand der Wasserablaufschale und der stromabwärtigen Wand herzustellen, indem beide in einer zur Oberfläche der Stirnwand oder der stromabwärtigen Wand gegeneinander verschoben werden, bis sowohl eine äußere Oberfläche der Stirnwand eine innere Oberfläche der stromabwärtigen Wand als auch eine rückwärtige Oberfläche des Befestigungsvorsprungs eine äußere Oberfläche der stromabwärtigen Wand berührt.Due to the convergence of the tangential planes, it is possible, despite certain dimensional tolerances of the evaporator chamber and the water drain pan, to establish a tight contact between the end wall of the water drain pan and the downstream wall, by sliding both towards the surface of the end wall or the downstream wall against each other, until both an outer surface of the end wall contacts an inner surface of the downstream wall and a rear surface of the attachment boss contacts an outer surface of the downstream wall.

Um die Wahrscheinlichkeit eines Wasserdurchtritts durch die Öffnung selber zu minimieren, liegt der äußere Kontaktpunkt oberhalb der Öffnung. So kann die Stirnwand, wenn der Befestigungsvorsprung diesen Kontaktpunkt erreicht, die Öffnung großenteils verdecken.In order to minimize the likelihood of water passage through the opening itself, the external contact point is above the opening. Thus, when the attachment projection reaches this point of contact, the end wall largely closes the opening cover up

Eine Oberkante der Stirnwand sollte wenigstens lokal tiefer liegen als der äußere Kontaktpunkt, um entweder sicherzustellen, dass wenn sich Wasser in einem Spalt zwischen Stirnwand und stromabwärtiger Wand sammelt, dieses Wasser eher über die Oberkante der Stirnwand in die Ablaufschale hinein als durch die Öffnung abfließt, oder von vornherein zu verhindern, dass Stirnwand und stromabwärtige Wand einen Spalt bilden können, der durch die Öffnung entwässert.A top edge of the end wall should be at least locally lower than the outer contact point to either ensure that if water collects in a gap between the end wall and the downstream wall, that water drains over the top edge of the end wall into the drain pan rather than through the opening, or to prevent in the first place that the end wall and the downstream wall can form a gap that drains through the opening.

Um einen dicht schließenden Kontakt zur stromabwärtigen Wand unmittelbar an einer Oberkante der Stirnwand herzustellen, verläuft diese Oberkante in Höhe der Öffnung.In order to establish a tightly closing contact with the downstream wall directly at an upper edge of the end wall, this upper edge runs at the level of the opening.

Ebenfalls zum Zwecke der Abdichtung zwischen Stirnwand und stromabwärtiger Wand sollten die äußere Oberfläche der Stirnwand und die innere Oberfläche der stromabwärtigen Wand eben sein.Also for purposes of sealing between the end wall and the downstream wall, the outer surface of the end wall and the inner surface of the downstream wall should be flat.

Ein von der stromabwärtigen Wand abgewandter Bereich der Wasserablaufschale kann auf einer Bodenplatte der Verdampferkammer aufliegen.A region of the water drainage tray facing away from the downstream wall can rest on a base plate of the evaporator chamber.

Ein der stromabwärtigen Wand zugewandter Bereich der Wasserablaufschale ist hingegen vorzugsweise von der Bodenplatte beabstandet.On the other hand, an area of the water drainage tray facing the downstream wall is preferably at a distance from the base plate.

Der dadurch geschaffene Zwischenraum zwischen der Wasserablaufschale und der Bodenplatte kann genutzt werden, um darin eine Heizung für die Wasserablaufschale unterzubringen und so zu verhindern, dass vom Verdampfer oder der stromabwärtigen Wand abfließendes Tauwasser in der Wasserablaufschale erneut gefriert.The space thus created between the water drain pan and the bottom plate can be used to accommodate a heater for the water drain pan therein and thus prevent condensation water flowing off the evaporator or the downstream wall from refreezing in the water drain pan.

Der von der stromabwärtigen Wand abgewandte Bereich der Wasserablaufschale kann zwischen eine sich unter dem Verdampfer erstreckende Abtauheizung und die Bodenplatte der Verdampferkammer eingreift. Insbesondere wenn die Abtauheizung selber plattenförmig und zur stromabwärtigen Wand abschüssig ist, braucht sich die Wasserablaufschale dann nicht unter dem gesamten Verdampfer zu erstrecken, um von dort abfließendes Tauwasser komplett aufzufangen.The area of the water drain pan facing away from the downstream wall can engage between a defrost heater extending below the evaporator and the bottom plate of the evaporator chamber. In particular, if the defrost heater itself is plate-shaped and slopes down to the downstream wall, the water drainage tray then does not have to extend under the entire evaporator in order to completely collect condensation water flowing from there.

Indem der der stromabwärtigen Wand zugewandten Bereich der Wasserablaufschale unter elastische Spannung gesetzt ist, kann eine Verschiebung der Wasserablaufschale durch Erschütterungen, insbesondere während eines Transports des Kältegeräts, verhindert werden.By putting the area of the water drainage tray facing the downstream wall under elastic tension, displacement of the water drainage tray due to vibrations, in particular during transport of the refrigeration appliance, can be prevented.

Vorzugsweise ist der abgewandte Bereich Druckkräften der Abtauheizung und der Bodenplatte ausgesetzt, die ein den einem Befestigungsvorsprung gegen die Kontaktpunkte treibendes Drehmoment auf die Ablaufschale ausüben und so dafür sorgen, dass der Kontakt am äußeren und am inneren Kontaktpunkt auch nach Erschütterungen bestehen bleibt.Preferably, the remote area is exposed to compressive forces from the defrost heater and the base plate which exert a torque on the drain pan that drives a mounting projection against the contact points, thus ensuring that the contact at the outer and inner contact point is maintained even after shocks.

Um die Ablaufschale entlang der einander gegenüberliegenden Oberflächen von Stirnwand und stromabwärtiger Wand eindeutig zu positionieren, kann ein oberer Rand der Öffnung wenigstens einen zu einem Scheitel schräg ansteigenden Randabschnitt aufweisen.In order to positively position the drain pan along the opposing surfaces of the end wall and the downstream wall, an upper edge of the opening may have at least one edge portion that rises obliquely to an apex.

Um die Ablaufschale kippsicher zu fixieren, sollten Befestigungsvorsprünge an der Wasserablaufschale auf beiden Seiten einer die Stirnwand kreuzenden Mittelebene vorgesehen sein.In order to fix the drain pan so that it cannot tip over, fastening projections should be provided on the water drain pan on both sides of a central plane crossing the end wall.

Wenn die Verdampferkammer und ein Lagerfach in einem gemeinsamen Innenbehälter untergebracht sind, kann die stromabwärtige Wand Teil eines Bauteils sein, das in den Innenbehälter eingefügt ist und Verdampferkammer und Lagerfach voneinander trenntIf the evaporation chamber and a storage compartment are housed in a common inner container, the downstream wall can be part of a component which is inserted into the inner container and separates the evaporation chamber and storage compartment from one another

Fig. 1 zeigt einen schematischen Schnitt durch ein Not-Frost-Kältegerät. Ein Korpus 1 und eine Tür 2 des Kältegeräts können eine oder mehrere Kammern umgeben, in Fig. 1 ist nur eine Kammer 3 gezeigt. Ein aus Kunststoff tiefgezogener Innenbehälter 4 grenzt die Kammer 3 gegenüber einer die Wände des Korpus 1 ausfüllenden Schaumstoffschicht 5 ab. 1 shows a schematic section through an emergency frost refrigeration device. A body 1 and a door 2 of the refrigerator can surround one or more chambers in 1 only one chamber 3 is shown. An inner container 4 deep-drawn from plastic delimits the chamber 3 from a foam layer 5 filling the walls of the body 1 .

Die Kammer 3 ist durch eine Verdampferschale 6 unterteilt in ein Lagerfach 7, eine Verdampferkammer 8 und eine Ventilatorkammer 9. Ein Ventilator 10 in der Ventilatorkammer 9 saugt Luft aus dem Lagerfach 7 über eine türnahe Einlassöffnung 11 in die Verdampferkammer 8, durch einen darin angeordneten Verdampfer 12 und eine Öffnung 14 in einer stromabwärtigen Wand 13 der Verdampferkammer 8 in die Ventilatorkammer 9 und stößt sie von dort wieder in das Lagerfach 7 aus.The chamber 3 is divided by an evaporator shell 6 into a storage compartment 7, an evaporator chamber 8 and a ventilator chamber 9. A ventilator 10 in the ventilator chamber 9 sucks air from the storage compartment 7 via an inlet opening 11 close to the door into the evaporator chamber 8, through an evaporator arranged therein 12 and an opening 14 in a downstream wall 13 of the evaporator chamber 8 into the fan chamber 9 and ejects them from there into the storage compartment 7 again.

Verdampferschale 6 und Verdampfer 12 sind in Fig. 2 in einem vergrößerten Schnitt und in Fig. 3 in einer teilweise auseinandergezogenen Ansicht gezeigt. Der Verdampfer 12 ist ein Lamellenverdampfer von im Wesentlichen quaderförmiger Gestalt. An der Unterseite des Verdampfers 12 erstreckt sich eine plattenförmige Abtauheizung 15. Die Abtauheizung 15 umfasst eine Wärmeverteilerplatte 16 aus Blech und ein Heizrohr 17, das auf der Wärmeverteilerplatte 16 in Schlangenlinien verlegt ist. Die Wärmeverteilerplatte 16 ist zur stromabwärtigen Wand 13 der Verdampferkammer 6 hin abschüssig. Geradlinige Abschnitte des Heizrohrs 17 sind auf der Wärmeverteilerplatte 16 in Richtung des Gefälles verlegt, so dass sie den Fluss von Tauwasser auf der Wärmeverteilerplatte 16 nicht behindern und jeweils in einen Zwischenraum zwischen Lamellen des Verdampfers 12 eingreifen und diese so effizient beheizen können.Evaporator dish 6 and evaporator 12 are in 2 in an enlarged section and in 3 shown in a partially exploded view. The evaporator 12 is a finned evaporator with an essentially cuboid shape. A plate-shaped defrost heater 15 extends on the underside of the evaporator 12. The defrost heater 15 comprises a heat distribution plate 16 made of sheet metal and a heating pipe 17 which is laid on the heat distribution plate 16 in serpentine lines. The heat spreader plate 16 slopes down to the downstream wall 13 of the evaporator chamber 6 . Straight portions of the heating pipe 17 are laid on the heat spreader plate 16 in the direction of the slope so that they do not impede the flow of condensed water on the heat spreader plate 16 and can each engage a gap between fins of the evaporator 12 to heat them efficiently.

Formkörper 18, 19 von im Wesentlichen plattenartiger Gestalt, z.B. aus expandiertem Polystyrol, füllen Zwischenräume zwischen der Oberseite des Verdampfers 12 und der (in Fig. 2 nicht dargestellten) Decke des Innenbehälters 4 bzw. zwischen der Abtauheizung 15 und einer Bodenplatte 49 der Verdampferschale 6 aus, um die vom Ventilator 10 angesaugte Luft verlustfrei durch den Verdampfer 12 zu leiten. Der untere Formkörper 19 bildet ferner zusammen mit der Bodenplatte 49 einen Boden der Verdampferkammer 8, der Verdampfer 12 und Abtauheizung 15 vom Lagerfach 7 isoliert. In Fig. 3 ist im Wesentlichen nur der obere Formkörper 18 zu sehen, der untere Formkörper 19 und die Wasserablaufschale 25 sind in der Verdampferschale 6 aufgenommen, so dass der untere Formkörper hinter deren Wand 13 und unter der Wasserablaufschale 25 verborgen ist.Shaped bodies 18, 19 of essentially plate-like shape, for example made of expanded polystyrene, fill gaps between the top of the evaporator 12 and the (in 2 not shown) cover of the inner container 4 or between the defrost heater 15 and a base plate 49 of the evaporator shell 6 in order to direct the air sucked in by the fan 10 through the evaporator 12 without loss. The lower molded body 19 also forms, together with the base plate 49, a base of the evaporator chamber 8, which insulates the evaporator 12 and defrost heater 15 from the storage compartment 7. In 3 essentially only the upper molded body 18 can be seen, the lower molded body 19 and the water drainage tray 25 are accommodated in the evaporator tray 6 so that the lower molded body is hidden behind its wall 13 and under the water drainage tray 25 .

Zwischen dem Verdampfer 12 und der stromabwärtigen Wand 13 erstreckt sich ein Graben 20 in Querrichtung des Korpus 1. Vom Boden des Grabens 20 aus führt ein Durchgang 21 durch die Wand 13 in die Ventilatorkammer 9. Von der Ventilatorkammer 9 aus verläuft eine Rohrleitung 22 durch die Rückwand des Korpus 1 ins Freie, insbesondere zu einer Verdunstungsschale 23 in einem Maschinenraum 24 des Korpus 1.Between the evaporator 12 and the downstream wall 13, a trench 20 extends in the transverse direction of the body 1. From the bottom of the trench 20, a passage 21 leads through the wall 13 into the fan chamber 9. From the fan chamber 9, a duct 22 runs through the Rear wall of the body 1 to the outside, in particular to an evaporation tray 23 in a machine room 24 of the body 1.

Eine Wasserablaufschale 25 (s. Fig. 2, 4 ) ist vorgesehen, um beim Abtauen des Verdampfers 12 durch die Abtauheizung 15 abfließendes Tauwasser aufzufangen und der Verdunstungsschale 23 zuzuleiten, ohne dass es sich in dem Formkörper 19 oder in Fugen zwischen diesem und der Verdampferschale 6 verteilen kann. Zu diesem Zweck umfasst die Wasserablaufschale 25 einen vorderen Bereich 26, der zwischen der Abtauheizung 15 und dem darunterliegenden Formkörper 19 eingeklemmt ist, um von der Abtauheizung 15 abfließendes Wasser aufzufangen, einen rinnenförmigen hinteren Bereich 27, der sich, vom Boden des Grabens 20 durch einen Zwischenraum 28 getrennt, über den Graben 20 erstreckt und mit einer an der stromabwärtigen Wand 13 anliegenden Stirnwand 33 abschließt, und einen Rohrstutzen 29, der sich ausgehend vom tiefsten Punkt des hinteren Bereichs 27 durch den Durchgang 21 der Wand 13 erstreckt und dessen freies Ende in die Rohrleitung 22 eingreift.A water drainage tray 25 (see Figures 2, 4 ) is provided in order to collect condensation water flowing through the defrost heater 15 during the defrosting of the evaporator 12 and to direct it to the evaporation tray 23 without it being able to distribute in the shaped body 19 or in gaps between this and the evaporator tray 6 . For this purpose, the water drainage tray 25 comprises a front area 26, which is clamped between the defrost heater 15 and the underlying shaped body 19 in order to collect water flowing off the defrost heater 15, a channel-shaped rear area 27, which extends from the bottom of the trench 20 through a Intermediate space 28 separated, extends over the trench 20 and ends with an end wall 33 resting against the downstream wall 13, and a pipe socket 29 which, starting from the deepest point of the rear area 27, extends through the passage 21 of the wall 13 and whose free end in the pipe 22 engages.

Der Zwischenraum 28 unter dem hinteren Bereich 27 bietet Platz für eine Heizung, die während des Abtauens des Verdampfers 12 auch den hinteren Bereich 27 und den Rohrstutzen 29 erwärmt, um sicherzustellen, dass vom Verdampfer 12 abgelaufenes Tauwasser tatsächlich die Verdunstungsschale 23 erreicht und nicht vorher im hinteren Bereich 27 oder im Rohrstutzen 29 erneut gefriert. Ein Stück dieser Heizung 48 ist in Fig. 3 am Ende des Rohrstutzens 29 gezeigt.The intermediate space 28 under the rear area 27 provides space for a heater which also heats the rear area 27 and the pipe socket 29 during the defrosting of the evaporator 12 in order to ensure that the evaporator 12 has run off Condensed water actually reaches the evaporation tray 23 and does not freeze again beforehand in the rear area 27 or in the pipe socket 29 . A piece of this heater 48 is in 3 shown at the end of the pipe socket 29.

Fig. 4 zeigt die Wasserablaufschale 25 in einer Einzeldarstellung. Der in der Perspektive der Fig. 3 vom Betrachter abgewandte vordere Bereich 26 ist eben und an seinen seitlichen Rändern von Stegen 30 begrenzt, die im fertig montierten Zustand beiderseits der Wärmeverteilerplatte 16 aufragen, um darauf fließendes Tauwasser verlustfrei dem hinteren Bereich 27 zuzuleiten. Zwei von dem vorderen Bereich 26 aufragende Klammern 31 sind vorgesehen, um auf eine Kältemittelleitung 32 (s. Fig. 2) des Verdampfers 12 aufzurasten und so die Wasserablaufschale 25 am Verdampfer 12 zu verankern. Die Stirnwand 33 bildet den dem Betrachter zugewandten Rand der Wasserablaufschale 25. 4 shows the water drainage tray 25 in an individual representation. The in the perspective of 3 The front area 26 facing away from the viewer is flat and delimited at its lateral edges by webs 30 which, in the fully assembled state, rise up on both sides of the heat distribution plate 16 in order to direct condensation water flowing thereon to the rear area 27 without loss. Two brackets 31 projecting from the front portion 26 are provided to attach to a refrigerant line 32 (see Fig. 2 ) of the evaporator 12 and to anchor the water drainage tray 25 on the evaporator 12. The front wall 33 forms the edge of the water drainage tray 25 facing the viewer.

Von einer dem Betrachter zugewandten Oberfläche 34 der Stirnwand 33 stehen benachbart zu deren oberer Kante 35 zwei Befestigungsvorsprünge 36 ab. In der Mitte zwischen den beiden Befestigungsvorsprüngen 36 ist die obere Kante 35 ausgeschnitten, um Platz zu lassen für einen von der stromabwärtigen Wand 13 in die Verdampferkammer 8 hinein vorspringenden, die Öffnung 14 umgebenden Ansaugstutzen 37 (s. Fig. 1, 2). Zumindest in einem oberen Bereich ist die Oberfläche 34 eben und vertikal.Two fastening projections 36 protrude from a surface 34 of the end wall 33 facing the viewer, adjacent to its upper edge 35 . The upper edge 35 is cut out in the middle between the two fastening projections 36 in order to leave room for an intake connection piece 37 (see Fig. Figures 1, 2 ). At least in an upper area, the surface 34 is flat and vertical.

Die Befestigungsvorsprünge 36 erstrecken sich durch Öffnungen 41, die beiderseits des Ansaugstutzens 37 in der stromabwärtigen Wand 13 gebildet sind. Fig. 5 zeigt eine Draufsicht auf eine solche Öffnung 41 und den darin eingreifenden Befestigungsvorsprung 36; Fig. 6 zeigt einen Längsschnitt durch einen Befestigungsvorsprung 36 und dessen Umgebung. Die Befestigungsvorsprünge 36 sind um eine zur Oberfläche 34 der Stirnwand 33 senkrechte, in der Schnittebene der Fig. 6 verlaufende Achse 38 rotationssymmetrisch und haben jeweils einen Stiel 39 und einen Kopf 40 mit einer der Oberfläche 34 zugewandten, flach kegelstumpfförmigen rückwärtigen Oberfläche 42 (s. Fig. 6). Wenn der vordere Bereich 26 der Wasserablaufschale 25 zwischen der Abtauheizung 15 und dem Formkörper 19 eingeklemmt ist, ist dadurch der hintere Bereich 27 elastisch vorgespannt, so dass die Befestigungsvorsprünge 36 von unten gegen eine obere Kante 46 der Öffnungen 41 drücken. Der Stiel 39 ist kürzer als die Wandstärke d der stromabwärtigen Wand 13, so dass die rückwärtigen Oberflächen 42 an den Oberkanten der Öffnungen 41 eine äußere, d.h. von der Verdampferkammer 8 abgewandte, Oberfläche 43 der stromabwärtigen Wand 13 berühren und an diesen entlang einer zu der rückwärtigen Oberfläche 42 tangentialen Ebene 44 aufwärts bis in die Stellung der Fig. 6 entlanggleiten, in der sich die rückwärtige Oberfläche 42 und die äußere Oberfläche 43 in einem Kontaktpunkt 50 der oberen Kante 46 berühren und die Oberfläche 34 der Stirnwand 33 an der inneren Oberfläche 45 der stromabwärtigen Wand 13 dicht anliegt. Wenn an dieser inneren Oberfläche 45 oberhalb der Kante 35 niedergeschlagener Reif abtaut, kann das Tauwasser von dort nur in die Wasserablaufschale 25 hinein abfließen; der Weg in den Zwischenraum 28 ist durch den Kontakt von stromabwärtiger Wand 13 und Stirnwand 33 versperrt.The attachment projections 36 extend through openings 41 formed in the downstream wall 13 on either side of the intake manifold 37 . figure 5 Fig. 4 shows a top view of such an opening 41 and the fastening projection 36 engaging therein; 6 shows a longitudinal section through a fastening projection 36 and its surroundings. The fastening projections 36 are perpendicular to the surface 34 of the end wall 33, in the sectional plane of 6 axis 38 are rotationally symmetrical and each have a stem 39 and a head 40 with a flat frustoconical rear surface 42 facing surface 34 (see Fig. 6 ). When the front area 26 of the water drainage tray 25 is clamped between the defrost heater 15 and the shaped body 19, the rear area 27 is elastically pretensioned so that the fastening projections 36 press against an upper edge 46 of the openings 41 from below. The stem 39 is shorter than the wall thickness d of the downstream wall 13 so that the rear surfaces 42 at the top edges of the openings 41 have an outer, ie facing away from the evaporator chamber 8, touch surface 43 of the downstream wall 13 and on this along a tangential to the rear surface 42 plane 44 up to the position of 6 sliding along in which the rear surface 42 and the outer surface 43 touch at a contact point 50 of the upper edge 46 and the surface 34 of the end wall 33 abuts the inner surface 45 of the downstream wall 13 in close contact. If frost deposited on this inner surface 45 above the edge 35 defrosts, the condensation water can only flow away from there into the water drainage tray 25; the path into gap 28 is blocked by contact of downstream wall 13 and end wall 33 .

Auch Tauwasser, das beim Abfließen von der Oberfläche 45 auf die obere Kante 46 einer der Öffnungen 41 stößt, kann diese Öffnung 41 nicht ohne weiteres passieren. Aufgrund der geringen Länge des Stiels 39 sind dieser und die obere Kante 46 der Öffnung 41 immer durch einen Zwischenraum 47 getrennt. Dieser Zwischenraum 47 verhindert, dass ein Tauwassertropfen durch Kapillarwirkung in die Öffnung 41 hineingezogen wird. Stattdessen wird er durch den dachähnlichen Verlauf des oberen Randes 46 mit zu einem Scheitel schräg ansteigenden Abschnitten seitwärts abgelenkt und erreicht so schließlich die Wasserablaufschale 25.Even dew water that encounters the upper edge 46 of one of the openings 41 as it flows off the surface 45 cannot easily pass through this opening 41 . Due to the small length of the stem 39, this and the upper edge 46 of the opening 41 are always separated by a gap 47. This intermediate space 47 prevents a drop of condensation water from being drawn into the opening 41 by capillary action. Instead, it is deflected sideways by the roof-like course of the upper edge 46 with sections that rise obliquely to a peak and thus finally reaches the water drainage tray 25.
