Abstract
Kältegerät mit einem Innenteil, das aus einem Polymermaterial auf Ligningrundlage gefertigt ist.Refrigerating appliance with an inner part, which is made of a polymer material on Ligningrundlage.
Description
Die vorliegende Erfindung betrifft ein Innenteil für ein Kältegerät, d. h. ein Teil, welches die Innenwandung des Kühlraums eines Kältegerätes, wie etwa eines Haushaltskühlschranks, -gefrierschranks oder dergleichen, oder einen Teil von dieser Innenwandung bildet oder zur Anbringung in diesem Innenraum vorgesehen ist, sowie ein mit wenigstens einem solchen Innenteil ausgestattetes Kältegerät.The present invention relates to an inner part for a refrigeration device, d. H. a part which forms the inner wall of the refrigerating space of a refrigerating appliance, such as a household refrigerator, freezer or the like, or a part of this inner wall or is provided for mounting in this interior, as well as a refrigerator equipped with at least one such inner part.
Derartige Innenteile werden herkömmlicherweise aus thermoplastischen Werkstoffen wie z. B. Polystyrol hergestellt, die aus nicht nachwachsenden Rohstoffen, insbesondere Erdöl, gewonnen werden. Die sortenreine Wiedergewinnung dieser Polymermaterialien beim Recycling eines Kältegerätes nach Gebrauch ist arbeitsaufwendig, insbesondere was den Innenbehälter des Kältegerätes angeht, der bei herkömmlichen Kältegeräten von einer Isolierschaummasse umgeben und mit dieser innig verbunden ist. Anstelle einer stofflichen Wiederverwertung dieser Materialien ist zwar auch eine thermische Verwertung möglich, dies ist jedoch wenig wünschenswert, da das dabei freiwerdende Kohlenstoffdioxid die globale CO2-Bilanz beeinträchtigt.Such internal parts are conventionally made of thermoplastic materials such. As polystyrene, which are obtained from non-renewable resources, especially petroleum. The sorted recovery of these polymer materials in recycling a refrigeration appliance after use is labor intensive, especially as regards the inner container of the refrigerator, which is surrounded in conventional refrigeration appliances by a Isolierschaummasse and connected to this intimately. Thermal recycling is also possible instead of reusing these materials, but this is not very desirable because the carbon dioxide released in the process affects the global CO2 balance.
Bei der Suche nach ökologischeren Alternativen für diese Werkstoffe sind im allgemeinen gesetzliche Bestimmungen wie etwa in Deutschland die Bedarfsgegenständeverordnung vom 10. April 1992 zu berücksichtigen, die Regelungen enthalten, die die Verbraucher vor Schadstoffen schützen sollen, die aus aus ungeeigneten Werkstoffen hergestellten Innenteilen austreten können.In the search for more ecological alternatives for these materials, general legal provisions, such as Germany's Consumer Goods Ordinance of 10 April 1992, are to be taken into account, which contain provisions to protect consumers from harmful substances that may escape from interior parts made of unsuitable materials.
Aufgabe der vorliegenden Erfindung ist, ein Kältegerät mit einem Innenteil zu schaffen, wobei das Innenteil aus einem physiologisch unbedenklichen, für die CO2-Bilanz neutralen Material besteht.Object of the present invention is to provide a refrigerator with an inner part, wherein the inner part consists of a physiologically acceptable, neutral for the CO2 balance material.
Ein solches Material ist ein Polymer auf Lignin-Grundlage. Lignin ist ein natürliches Polymer, das bei der Herstellung von Zellulose aus Holz als Abfallprodukt anfällt.One such material is a lignin-based polymer. Lignin is a natural polymer obtained as a waste product in the production of cellulose from wood.
Reines Lignin ist ungünstigerweise spröde, doch ist es mit geeigneten Zusatzstoffen zu einem belastbaren thermoplastischen Polymermaterial verarbeitbar. Ein zum Flexibelmachen des Lignins bevorzugter Zusatzstoff sind Fasern, wobei natürliche Fasern, insbesondere pflanzliche Fasern wie etwa Hanf- oder Flachsfasern wegen ihrer CO2-Neutralität gegenüber Kunstfasern bevorzugt sind.Pure lignin is unfavorably brittle, but it can be processed with suitable additives to form a load-bearing thermoplastic polymer material. A preferred additive for making the lignin flexible is fiber, with natural fibers, especially vegetable fibers such as hemp or flax being preferred because of their CO2 neutrality over synthetic fibers.
Aus einem solchen Polymermaterial können beliebige Innenteile, insbesondere Kältegeräte-Innenbehälter, Türinnenverkleidungen, Kühlguträger, sowohl zur Anbringung in einem Innenbehälter als auch an einer Türinnenverkleidung, sowie Auszugkästen gefertigt werden.From such a polymer material, any internal parts, in particular refrigeration device inner container, door inner panels, Kühlguträger, both for mounting in an inner container and on a door inner lining, and pull-out boxes are made.
Ein derartiges Polymermaterial wird von der Fa. Tecnaro, Eisenach unter dem Handelsnamen Arboform vertrieben. Die zur Herstellung der genannten Innenteile herkömmlicherweise eingesetzten Technologien des Spritzgießens bzw. Tiefziehens sind bei diesem thermoplastischen Polymermaterial in gleicher Weise wie bei herkömmlichen Werkstoffen anwendbar.Such a polymer material is marketed by Tecnaro, Eisenach under the trade name Arboform. The technologies of injection molding or deep drawing conventionally used for producing said internal parts are applicable to this thermoplastic polymer material in the same way as in conventional materials.
Der „ökologische” Charakter der Innenteile bzw. eines mit derartigen Innenteilen ausgestatteten Kältegeräts ist für den Anwender aufgrund des holzähnlichen Erscheinungsbildes von aus Lignin-Polymermaterial gefertigten Teilen unmittelbar augenfällig. Die aus dem Lignin-Polymermaterial gefertigten Innenteile können nach Gebrauch des Kältegeräts verbrannt werden, wobei nicht mehr Kohlendioxid frei gesetzt wird, als zuvor durch die zur Herstellung des Materials genutzten Pflanzen gebunden wurde. Die Teile sind daher CO2-neutral. Darüber hinaus ist das Polymermaterial kompostierbar, d. h. im Gegensatz zu Teilen aus herkömmlichen Thermoplasten können die erfindungsgemäßen Innenteile deponiert und auf natürlichem Wege abgebaut werden.The "ecological" character of the internal parts or a refrigeration device equipped with such internal parts is immediately obvious to the user due to the wood-like appearance of parts made of lignin polymer material. The internal parts made of the lignin polymer material can be burned after use of the refrigerator, with no more carbon dioxide being released than was previously bound by the plants used to produce the material. The parts are therefore CO2-neutral. In addition, the polymer material is compostable, d. H. In contrast to parts made of conventional thermoplastics, the internal parts according to the invention can be landfilled and degraded by natural means.
