Description

Die Erfindung betrifft einen Lamellenverdampfer für Haushalt-Umluft-Kühl- und Gefriergeräte nach dem Oberbegriff des Anspruchs 1. Sie betrifft im engeren Sinn eine vormontierte Verdampfereinheit mit welcher bei der seriellen Fertigung besagte Geräte komplettiert werden.The invention relates to a finned vaporizer for domestic convection refrigerators and freezers.

Kühlschränke bzw. Gefriergeräte, welche nach dem Umluftkälte-Prinzip arbeiten (auch bekannt unter der Handelsbezeichnung "no frost"-Geräte) besitzen zusätzlich ein Luftgebläse. Über ein Kanalsystem wird mit Hilfe besagten Ventilators die Luft aus dem Geräteinnenraum dem Verdampfer zugeführt, dort abgekühlt, entfeuchtet und anschließend wiederum zurückgeblasen. Da sich Luftfeuchtigkeit am Verdampfer als Reif niederschlägt, wird in den Betriebspausen des Kompressors der Verdampfer durch eine Intervallheizung mit einer Leistung von ca. 150 Watt automatisch abgetaut. Das Tauwasser wird zur Verdunstung in eine oberhalb des Kompressors angeordnete Schale geleitet. Zusätzlich im Geräteinnenraum untergebrachte Kühlakkus verlängern, vornehmlich bei Netzspannungsausfällen, die Lagerdauer des eingebrachten Kühl- und Gefrierguts. (Aus HEA-Bilderdienst, Serie: Kühl- und Gefriergeräte; Ausgabe Juli 1986).Refrigerators and freezers that work according to the forced-air cooling principle (also known under the trade name "no frost" devices) also have an air blower. Via a duct system, the fan is used to supply the air from the interior of the device to the evaporator, where it is cooled, dehumidified and then blown back. Since air moisture condenses on the evaporator as frost, the evaporator is automatically defrosted by an interval heater with an output of approx. 150 watts during the breaks in operation of the compressor. The condensation water is led into a bowl arranged above the compressor for evaporation. In addition, refrigeration accumulators housed in the interior of the device extend the storage time of the refrigerated and frozen goods, especially in the event of a power failure. (From HEA picture service, series: refrigerators and freezers; July 1986 edition).

Aus der DE 41 43 254 A1 ist eine "Abtauvorrichtung" bekannt. Die Abtauvorrichtung umfaßt eine Isolietplatte sowie eine darüber angeordnete Heizplatte. Die Heizplatte besteht aus einer dünnen Platte aus Aluminium oder dgl. und einem Heizkabel, das an der Unterseite der dünnen Platte angeordnet ist, um die von dem Heizkabel erzeugte Wärme auf die Träger, die Rippen und das Kühlmittelrohr des Verdampfers zu übertragen. Hinter dem rückseitigen Teil des Verdampfers ist abwärts gerichtet ein Abflußkanal vorgesehen, der das vom Verdampfer beim Abtauvorgang abtropfende Wasser sammelt.A "defrosting device" is known from DE 41 43 254 A1. The defrosting device comprises an insulating plate and a heating plate arranged above it. The heating plate consists of a thin plate of aluminum or the like. And a heating cable which is arranged on the underside of the thin plate in order to transfer the heat generated by the heating cable to the carrier, the fins and the coolant tube of the evaporator. Behind the rear part of the evaporator, a drainage channel is provided which collects the water dripping from the evaporator during the defrosting process.

Des weiteren ist aus dem GM 87 12 962 eine "Vorrichtung zum Befestigen eines Kastenverdampfers" bekannt. Besagter Kastenverdampfer besitzt aus seinem Lamellenpaket seitlich herausragende Rohrbögen. Über diese Rohrbögen werden von beiden Seiten her entsprechende Formteile formschlüssig aufgesteckt. Beide Formteile besitzen erhaben angeformte Zapfen und Stollen über welche der Kastenverdampfer in seitlichen Einschubnuten des Gefrierschrank-Innenbehälters gehaltert wird.Furthermore, a "device for attaching a box evaporator" is known from GM 87 12 962. Said box evaporator has laterally protruding pipe bends from its plate package. Corresponding molded parts are plugged in from both sides using these pipe bends. Both molded parts have raised pegs and studs via which the box evaporator is held in the side slots of the freezer inner container.

Beim letztgenannten Stand der Technik ist lediglich die Befestigung und Lagefixierung des eigentlichen Verdampfers ohne dessen eingangs erwähnten Zubehörteile vorgesehen.In the latter prior art, only the attachment and position fixing of the actual evaporator is provided without the accessories mentioned above.

Der Erfindung liegt die Aufgabe zugrunde, bekannte Ausführungen weiterzubilden bzw. zu verbessern, d. h. eine einfach vorzufertigende komplette Verdampfereinheit zu schaffen (einschließlich der Abtauvorrichtung und aller erforderlichen Zubehör-Komponenten), die in Umluft-Kühlgeräten einfach und rasch einbaubar ist.The invention has for its object to develop or improve known designs, d. H. to create an easy-to-manufacture complete evaporator unit (including the defrosting device and all necessary accessory components) that can be easily and quickly installed in circulating air cooling units.

Diese Aufgabe wird gemäß der Erfindung durch die kennzeichnenden Merkmale des Anspruchs gelöst.This object is achieved according to the invention by the characterizing features of the claim.

Die mit der Erfindung erzielbaren Vorteile ergeben sich bereits aus Art und Weise der Aufgabenstellung; als weitere Vorteile sind anzusehen: Reduzierung der Montagekosten bei serieller Fertigung; in Kundendienstfällen kann die erfindungsgemäße Verdampfereinheit mit verringertem Arbeits- und Kostenaufwand ausgetauscht werden.The advantages that can be achieved with the invention result from the type of task; further advantages are to be seen: reduction of assembly costs for serial production; in customer service cases, the evaporator unit according to the invention can be replaced with reduced labor and cost.

Gemäß Fig. 1 ist eine aus diversen Einzelteilen bestehende Verdampfereinheit 1 über Führungsnoppen und Auflagen an hochgelegener Stelle in den Innenbehälter eines teilweise dargestellten Umluftkühlgerätes 2 eingeschoben und hierin mit einer Schiene ortsfest und in Schräglage gesichert gehaltert. Zur Luftumwälzung dient ein Gebläse 3. Die Schräglage besagter Verdampfereinheit 1 ermöglicht einen ungehinderten Ablauf entstehenden Tauwassers in einen Trichter 4.1, an evaporator unit 1 consisting of various individual parts is inserted via guide knobs and supports at a high point into the inner container of a circulating air cooling device 2, which is shown in part, and is secured therein with a rail and secured in an inclined position. A blower 3 is used for air circulation. The inclined position of said evaporator unit 1 enables an unimpeded drainage of condensation water into a funnel 4.

Gemäß Fig. 2 besteht eine komplette Verdampfereinheit 1 aus mehreren Einzelkomponenten und wird wie folgt zusammengesetzt bzw. vormontiert: Ein wannenförmig ausgebildetes Einschubunterteil 5, hergestellt als Kunststoff-Spritzgießteil, besitzt mehrere räumlich voneinander getrennte Einlegetaschen 6 zur lagesicheren Aufnahme von Kühlakkus 7. An den hochgezogenen Rändern des Einschub-Unterteils 5 sind senkrecht nach oben ragende, federnde Rasthaken 8 angeformt. Eine Formausnehmung 9 dient der Aufnahme eines Temperaturfühlers 10. Das Einschubunterteil 5 wird durch einen Formdeckel 11 wärmeisoliert und paßgenau verschlossen. Hierzu ist besagter Formdeckel 11 mittels Alufolie kaschiert und die Kühlakkus 7 sind in nicht dargestellter Weise noch zusätzlich durch wärmedämmende Schaumstofformteile (beispielsweise Styropor) abgedeckt. Nach Verlegung der Leitung 12 des Temperaturfühlers 10 und der Montage eines Wärmeleitblechs 13 ist das Einschubunterteil 5 fertig bestückt. Ein Einschub-Oberteil 14 besitzt eine schräg geneigte Bodenfläche 15 und hierauf angeformte Flüssigkeits-Leitrippen 16 sowie eine Ablauföffnung 17 für das Verdampfer-Tauwasser. An den Seitenwandungen des Einschub-Oberteils 14 sind rechteckige Ausnehmungen 18 vorgesehen, deren maßliche Anordnung der Lage der Rasthaken 8 im Einschub-Unterteil 5 entspricht. Auf die Unterseite der Bodenfläche 15 des Einschub-Oberteils 14 wird eine Flächenheizung 19 aufgebracht. Die Flächenheizung 19 verhindert ein erneutes Gefrieren des von den Verdampferlamellen abtropfenden Tauwassers. Besagte Flächenheizung 19 stellt ein Fertigteil dar. Es besteht aus einer einseitig selbstklebenden, 0,15 mm starken Alufolie. Die Klebeschicht ist mit einem abziehbaren Schutzfilm abgedeckt. Auf der Foliengegenseite ist eine mäanderförmig verlegte und thermisch abgesicherte Heizkordel aufgeschweißt; deren Leistung beträgt in etwa 86 Watt bei 220 bis 240 Volt Netzspannung. Die Klebeschicht der Flächenheizung 19 gewährleistet eine gut wärmeleitende Verbindung zur Unterseite der Bodenfläche 15 des Einschub-Oberteils 14. Das so komplettierte Einschub-Oberteil 14 wird nun mit dem fertig bestückten Einschub-Unterteil 5 form- und kraftschlüssig (über die erwähnten Rasthaken 8 und Ausnehmungen 18) verschnappt.2, a complete evaporator unit 1 consists of several individual components and is assembled or preassembled as follows: A trough-shaped insert lower part 5, produced as a plastic injection molded part, has a plurality of spatially separated insertion pockets 6 for securely holding cooling accumulators 7 Edges of the lower insert part 5 are formed on the resilient locking hooks 8 projecting vertically upwards. A mold recess 9 serves to accommodate a temperature sensor 10. The insertion lower part 5 is thermally insulated by a mold cover 11 and closed with a precise fit. For this purpose, said mold cover 11 is laminated by means of aluminum foil and the cooling accumulators 7 are additionally covered in a manner not shown by heat-insulating foam molded parts (for example polystyrene). After laying the line 12 of the temperature sensor 10 and installing a heat conducting plate 13, the lower insert part 5 is fully equipped. An insert upper part 14 has an obliquely inclined base surface 15 and liquid guide ribs 16 formed thereon and an outlet opening 17 for the evaporator condensation water. Rectangular recesses 18 are provided on the side walls of the insert upper part 14, the dimensional arrangement of which corresponds to the position of the latching hooks 8 in the insert lower part 5. A surface heater 19 is applied to the underside of the bottom surface 15 of the upper insert part 14. The surface heating 19 prevents the condensation water dripping from the evaporator fins from freezing again. Said surface heating 19 represents a finished part. It consists of a self-adhesive 0.15 mm thick aluminum foil. The adhesive layer is covered with a removable protective film. On the opposite side of the film is a meandering and thermally secured heating cord welded on; their output is approximately 86 watts at 220 to 240 volts mains voltage. The adhesive layer of the surface heating 19 ensures a good heat-conducting connection to the underside of the bottom surface 15 of the upper insert part 14. The upper insert part 14 thus completed is now positively and non-positively connected to the inserted lower part 5 (via the mentioned locking hooks 8 and recesses 18) snapped.

Der eigentliche Lamellenverdampfer 20 ist nun in nicht näher dargestellter Weise auf der Bodenfläche 15 des Einschub-Oberteils 14 befestigbar. Letztendlich erfolgt die Komplettierung vorerwähnten Lamellenverdampfers 20 mit der Verdampferheizung 21 (enteist die Lamellen), den einsteckbaren Verdampferfühlern 22, 23 und dem über Haltewinkel 24 fixierten Kühlmittel-Saugrohr 25. Nach Verlegung aller elektrischen Zuleitungen und Verbindungen wird die derart komplettierte Verdampfereinheit 1, wie eingangs erwähnt, über Führungsnoppen und Auflagen in den hierfür vorgesehenen Raum eines Kühlgeräte-Innenbehälters eingeschoben.The actual lamella evaporator 20 can now be fastened in a manner not shown on the bottom surface 15 of the upper insert part 14. Ultimately, the above-mentioned finned vaporizer 20 is completed with the evaporator heater 21 (de-icing the fins), the plug-in evaporator sensors 22, 23 and the coolant suction pipe 25 fixed via the holding bracket 24 mentioned, inserted via guide knobs and pads in the space provided for this purpose in a cooling unit inner container.
