Description
Die Offenlegungsschrift
Die vorliegende Erfindung betrifft ein No-Frost-Kältegerät mit einer Verdampfer-Baugruppe. Eine solche Baugruppe umfasst herkömmlicherweise einen gehäuseartigen Träger, auf dem sich ein Lamellenverdampfer abstützt, der über eine Lufteintritts- und eine Luftaustrittsöffnung, von einem Ventilator zwangsbelüftet ist, der am Träger angebracht ist, um Luft zunächst über und dann in einen Luftkanal zu drücken, über den sie einen Kühlraum des Kältegeräts erreicht. Bei einer bekannten Verdampfer-Baugruppe ist an einer Rückseite des Gehäuses ein Fenster gebildet, in das eine Platte, durch eine umlaufende flexible Gummilippe mit der Gehäuserückwand verbunden, gedämpft schwingfähig eingesetzt ist. In der Platte ist die Luftaustrittsöffnung des Gehäuses gebildet, und über der Luftaustrittsöffnung ist ein Ventilator montiert. Eine Wand eines an die Luftaustrittsöffnung anschließenden Luftkanals ist in Schlitzen der Gummilippe verrastet.The present invention relates to a no-frost refrigerator with an evaporator assembly. Such an assembly conventionally comprises a box-type carrier on which is supported a vane evaporator forcibly vented via an air inlet and an air outlet, by a ventilator mounted on the carrier to initially force air over and then into an air duct it reaches a cold room of the refrigerator. In a known evaporator assembly, a window is formed on a rear side of the housing, in which a plate, connected by a circumferential flexible rubber lip with the rear wall of the housing, is used damped vibrated. In the plate, the air outlet opening of the housing is formed, and above the air outlet opening, a fan is mounted. A wall of a subsequent to the air outlet opening air duct is locked in slots of the rubber lip.
Aufgabe der vorliegenden Erfindung ist, eine schnell und einfach zu montierende Verdampferbaugruppe zu schaffen.Object of the present invention is to provide a fast and easy to install evaporator assembly.
Die Aufgabe wird gelöst durch ein No-Frost-Kältegerät mit den Merkmalen des Anspruchs 1. Die einteilige Ausbildung des Stegs mit der Wand und damit mit dem Träger reduziert zum einen montagevereinfachend die Teilezahl der Baugruppe, zum anderen vereinfacht es die Positionierung eines, z.B. den Ventilator tragenden und zugleich einen Teil einer Luftführung bildenden Trägerelements, das mit seinem dem Durchgang zugewandten offenen Seite die Wandung des Luftkanals vervollständigt.The object is achieved by a no-frost refrigeration device with the features of
Vorzugsweise ist der Ventilator an dieser Schale montiert.Preferably, the fan is mounted on this shell.
Vorzugsweise bilden der Steg und eine Wand der Schale eine Labyrinthdichtung, so dass der von dem Ventilator angetriebene Luftstrom im wesentlichen verlustfrei den Kühlraum des Kältegeräts erreicht.
Um den Zusammenbau zu beschleunigen, sind der Steg und eine Wand der Schale - bei der es sich auch um die oben erwähnte, an der Labyrinthdichtung beteiligte Wand handeln kann - mit zusammenwirkenden Rastmitteln versehen.
Ein Schaufelrad und ein Motor des Ventilators sind vorzugsweise auf entgegengesetzten Seiten eines Bodens der Schale angeordnet, so dass von dem Motor abgegebene Wärme nicht unmittelbar in den von dem Ventilator umgewälzten Luftstrom gelangen kann.Preferably, the web and a wall of the shell form a labyrinth seal, so that the air flow driven by the fan reaches the cooling space of the refrigeration device substantially loss-free.
To accelerate the assembly, the web and a wall of the shell - which may also be the above-mentioned wall involved in the labyrinth seal - are provided with cooperating detent means.
A paddle wheel and a motor of the fan are preferably arranged on opposite sides of a bottom of the shell, so that heat emitted by the motor can not pass directly into the air flow circulated by the fan.
