KältegerätRefrigeration appliance

Die Erfindung bezieht sich auf ein Kältegerät, insbesondere ein Kühl- und/oder Gefriergerät, mit aus Kunststoff bestehenden Teilen, wie z. B. Türdichtung, Tiefkühlfachtürdichtung, Verdampferstütze, kunststoffisolierte Verdrahtung, Verkleidungskeder.The invention relates to a refrigeration device, in particular a refrigerator and/or freezer, with plastic parts, such as door seal, freezer compartment door seal, evaporator support, plastic-insulated wiring, panel piping.

Ein Kältegerät, insbesondere ein Kühl- und/oder Gefriergerät für den Haushalt, weist üblicherweise eine ganze Anzahl von Teilen auf, die ganz aus Kunststoff bestehen oder beispielsweise im Fall der Verdrahtung, mittels Kunststoff isoliert sind. Derartige Teile bestehen derzeit üblicherweise aus PVC oder PVC-Verbindungen.A refrigeration appliance, in particular a refrigerator and/or freezer for the home, usually has a whole number of parts that are made entirely of plastic or, for example in the case of wiring, are insulated using plastic. Such parts currently usually consist of PVC or PVC compounds.

Im Zuge eines zunehmenden Umweltbewußtseins und strenger gesetzlicher Auflagen bezüglich der Luftreinhaltung sind die vorgenannten Teile bedenklich, weil zum einen bei der Herstellung Chlorverbindungen oder Halogenverbindungen erforderlich sind und zum anderem bei der Entsorgung oder im Brandfall Dioxine, Furane und Halogensäuren entstehen können.In the wake of increasing environmental awareness and stricter legal requirements regarding air pollution control, the aforementioned parts are of concern because, on the one hand, chlorine compounds or halogen compounds are required during production and, on the other hand, dioxins, furans and halogen acids can be produced during disposal or in the event of fire.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Kältegerät anzugeben, das nicht oder in erheblich geringerem Maß als heute üblich mit diesen vorstehend genannten Nachteilen behaftet ist.The invention is therefore based on the object of specifying a refrigeration device which is not affected by the above-mentioned disadvantages or is affected to a considerably lesser extent than is usual today.

Diese Aufgabe wird bei einem Kältegerät der eingangs genannten Art erfindungsgemäß dadurch gelöst, daß dieThis object is achieved in a refrigeration device of the type mentioned above in that the

Türdichtung halogenfrei ist und einen thermoplastischen Elastomer umfaßt.Door seal is halogen-free and contains a thermoplastic elastomer.

Auf diese Weise ist es gewährleistet, daß das mit Ausnahme des Kunststoffinnenbehälters, der Türinnenverkleidung und der geschäumten Isolierung massereichste Kunststoffteil weder zu dessen Herstellung Halogen, und insbesondere Clor erforderlich macht noch bei der Entsorgung oder Verbrennung Halogene, insbesondere Chlor, in organischen oder Säure-Verbindungen freisetzt.In this way, it is ensured that the plastic part, which has the highest mass, with the exception of the plastic inner container, the inner door panel and the foamed insulation, neither requires halogens, and in particular chlorine, for its production nor releases halogens, in particular chlorine, in organic or acidic compounds during disposal or incineration.

In vorteilhafter Weiterbildung der Erfindung ist es vorgesehen, daß die Türdichtung eines separaten oder integrierten Gefrierfachs halogenfrei ist und einen thermoplastischen Elastomer umfaßt. Ebenso kann eine Verdampferstütze vorgesehen sein, welche halogenfrei ist und einen thermoplastischen Elastomer umfaßt.In an advantageous development of the invention, it is provided that the door seal of a separate or integrated freezer compartment is halogen-free and comprises a thermoplastic elastomer. An evaporator support can also be provided which is halogen-free and comprises a thermoplastic elastomer.

Des weiteren kann die gesamte kunststoffisolierte Verdrahtung halogenfrei sein und mittels eines thermoplatischen Elastomers isoliert sein.Furthermore, the entire plastic-insulated wiring can be halogen-free and insulated using a thermoplastic elastomer.

Außerdem kann es vorgesehen sein, daß ein halogenfreier Verkleidungskeder vorgesehen ist, welcher einen thermoplastischen Elastomer umfaßt.In addition, it can be provided that a halogen-free cladding piping is provided which comprises a thermoplastic elastomer.

In besonders vorteilhafter Ausgestaltung der Erfindung eignet sich als thermoplastischer Elastomer eine Verbindung mit der Bezeichnung PP-EPDM und/oder SEBS.In a particularly advantageous embodiment of the invention, a compound called PP-EPDM and/or SEBS is suitable as a thermoplastic elastomer.

Vorstehend erstgenannte Verbindung ist ein Mischung aus Polypropylenelastomer und Ethylen-Propylen-Dienpolymerisat-(Terpolymer)-Kautschuk, der in der Literatur auch mit EPT abgekürzt wird. Die zweitgenannte Verbindung ist einThe first compound mentioned above is a mixture of polypropylene elastomer and ethylene-propylene-diene polymer (terpolymer) rubber, which is also abbreviated to EPT in the literature. The second compound is a

Gemisch aus Polystyrol und Polypropylen und wird in der Literatur als Styrolethylenbutadinstyrol bezeichnet. Hierbei ist die Zusammensetzung der einzelnen thermoplastischen Elastomere von der Dicke, der Temperaturbeständigkeit, der Weichheit und den übrigen Eigenschaften des mit einem der vorstehend genannten Stoffe hergestellten Kunststoffteils abhängig.Mixture of polystyrene and polypropylene and is referred to in the literature as styrene-ethylene-butadiene-styrene. The composition of the individual thermoplastic elastomers depends on the thickness, temperature resistance, softness and other properties of the plastic part made with one of the above-mentioned materials.
