In order to prevent the protective effect from being reduced by mechanical stresses, the invention provides in its embodiment that the coated vapor shield (1) is arranged in a floating manner on the carrier part (2) of the chimney (3). <IMAGE>

Description

Die Erfindung betrifft die Vermeidung von stärker anhaftenden Verunreinigungen, insbesondere von Fetten, an Haushaltsgeräten mit angeströmten beschichteten Teilen.The invention relates to the prevention of more adhering contaminants, especially greases, on household appliances with coated parts.

Bei Haushaltgeräten ist allgemein das Problem bekannt, dass schon nach kurzer Betriebsdauer helle Gitter oder Flächen aus Kunststoff durch auf sie wirkende Wrasen verschmutzt werden. Der kondensierte Wrasen brennt dabei an der Oberfläche ein, reagiert chemisch mit dem Kunststoff und verfärbt ihn so nachhaltig, dass nach einer gewissen Einwirkungsdauer eine erfolgreiche Reinigung kaum mehr möglich ist.With household appliances, the problem is generally known that after a short time Operating time bright grids or plastic surfaces due to vapors acting on them become dirty. The condensed vapor burns on the surface, reacts chemically with the plastic and discolours it so sustainably that after one After a certain period of exposure, successful cleaning is hardly possible.

Deshalb wurde in der DE 44 20 820 A1 für Lüftergitter und Bedienteile aus Kunststoff vorgeschlagen, dass zumindest der von Wrasen angeströmte Teilbereich der Kunststoffteile mit einer Silikatschicht bedeckt wird. Das Aufbringen der Silikatschicht erfolgt im Tauchverfahren. Eine solche Silikatschicht zeichnet sich durch hohe Härte aus und soll selbst eine Reinigung mit scharfen Putzmitteln bzw. im Geschirrspüler gestatten. Nachteilig bei dieser Art der Beschichtung ist es, dass das Reinigen zwar erleichtert, die Haftung von Fetten aber nicht von vornherein vermindert wird.Therefore, in DE 44 20 820 A1 for fan grilles and control panels made of plastic suggested that at least the sub-area of the Plastic parts are covered with a layer of silicate. The application of the silicate layer takes place in the immersion process. Such a silicate layer is characterized by high hardness and should allow cleaning with sharp detergents or in the dishwasher. The disadvantage of this type of coating is that cleaning makes it easier Adhesion of fats is not reduced from the outset.

Eine andere Variante wird in der EP 0 692 013 B1 vorgeschlagen. Hier wird auf die Oberfläche, die einer Verunreinigung durch organische Lebensmittelablagerungen ausgesetzt ist, eine Beschichtung aufgetragen, die nach dem Trocknen und Verunreinigen mit Wasser oder wässriger Lösung leicht entfernbar ist.
Diese Lösung hat den gravierenden Nachteil, dass die Oberflächenbeschichtung zyklisch wiederholt werden muss.
Another variant is proposed in EP 0 692 013 B1. Here, a coating is applied to the surface that is exposed to contamination by organic food deposits, which can be easily removed after drying and contamination with water or aqueous solution.
This solution has the serious disadvantage that the surface coating has to be repeated cyclically.

Aufgabe der Erfindung ist es, stark anhaftende Verunreinigungen, insbesondere aus Wrasen kommend, zu verhindern.The object of the invention is to remove strongly adhering contaminants, in particular from Coming vapors to prevent.

Gelöst wird diese Aufgabe mit den Merkmalen des Anspruchs 1, vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved with the features of claim 1, advantageous Refinements are the subject of the dependent claims.

Erfindungsgemäß ist bei einem Haushaltsgerät mit von Wrasen angeströmten beschichteten Teilen vorgesehen, dass die Teile aus Polycarbonat bestehen und eine Silikonhardcoatingbeschichtung aufweisen. Solche Teile können bevorzugt Wrasenschirme oder auch Abdeckungen von Lampen bei Wrasenschirmen oder Dunstabzugshauben sein.According to the invention is in a household appliance with the flow of vapors coated parts provided that the parts are made of polycarbonate and a Have silicone hard coating. Such parts can be preferred Vapor umbrellas or covers of lamps for vapors or Extractor hoods.

Wrasenschirme aus Polycarbonat mit einer bevorzugten Dicke bis zu 10 mm werden dabei tauchbeschichtet, so dass 100 % der Oberfläche gegen die Einwirkung jeglicher Fette geschützt sind. Die derart beschichtete Oberfläche weist niedrige Oberflächenspannungen auf und zeichnet sich durch niedrige Polarität aus.Vapor umbrellas made of polycarbonate with a preferred thickness up to 10 mm while dip-coated, so that 100% of the surface against the influence of everyone Fats are protected. The surface coated in this way has a low surface Surface tensions and is characterized by low polarity.

Um zu verhindern, dass durch mechanische Spannungen die Schutzwirkung reduziert wird, sieht die Erfindung in ihrer Ausgestaltung vor, dass der beschichtete Wrasenschirm schwimmend auf dem Trägerteil der Esse angeordnet wird. Dies kann durch ein zwischen dem Trägerteil der Esse und dem Wrasenschirm angeordnetes Silikonschaumprofil erfolgen.To prevent mechanical protection from reducing the protective effect In its embodiment, the invention provides that the coated vapor screen is arranged floating on the support part of the chimney. This can be done through an between silicone foam profile arranged on the support part of the chimney and the vapor shield respectively.

Eine derartige Anordnung eines Wrasenschirmes ist in der Zeichnung dargestellt. Der Wrasenschirme 1 aus Polycarbonat mit einer Dicke von 8 mm ist mit Silikonhardcoating tauchbeschichtet. Er liegt spannungsfrei auf dem zwischen dem Trägerteil 2 der Esse 3 und dem Wrasenschirm 1 angeordneten Silikonschaumprofil auf. Ebenso sind die Abdeckungen der Lampen 4 mit Silikonhardcoating beschichtet.Such an arrangement of a vapor screen is shown in the drawing. The Vapor umbrellas 1 made of polycarbonate with a thickness of 8 mm is with silicone hard coating dip coated. It lies tension-free on that between the carrier part 2 of the chimney 3 and the vapor screen 1 arranged silicone foam profile. Likewise, they are Lamp 4 covers coated with silicone hard coating.
