Demnach werden zumindestens solche Oberflächen, die von der Bildung von Rückständen betroffen sein können und insbesondere auch mit Wäschestücken in Berührung kommen, derart gestaltet, dass die Hafteigenschaften von Flüssigkeiten und/oder Verunreinigungen an diesen Oberflächen beseitigt oder zumindest geringer werden. Überwiegend reicht es aus, die Hafteigenschaften von Flüssigkeiten an den betreffenden Oberflächen zu beseitigen, indem die Flüssigkeiten die Oberflächen nicht benetzen sondern hieran abperlen. Die Oberflächen bleiben dadurch jedenfalls dann, wenn sie nicht in der Flüssigkeit eingetaucht sind, größtenteils trocken und insbesondere trocknet die Flüssigkeit nicht an den Oberflächen, wodurch in der Flüssigkeit vorhandene Zusätze als Rückstände auf den Oberflächen zurückbleiben und hieran anhaften.A method for solving the problem mentioned at the outset shows the measures of Claim 1 on. Accordingly, at least those surfaces that are from the Formation of residues can be affected and especially with Items of laundry come into contact, designed in such a way that the adhesive properties of Liquids and / or contaminants on these surfaces are eliminated or at least decrease. It is mostly sufficient to adhere to the adhesive properties of liquids Eliminate the surfaces in question by removing the liquids from the surfaces do not wet but roll off. In any case, the surfaces remain then, when not immersed in the liquid, mostly dry and in particular, the liquid does not dry on the surfaces, which in the Liquid additives remain as residues on the surfaces and cling to it.
Vorzugsweise werden die Hafteigenschaften der in Betracht kommenden Oberflächen dadurch beseitigt bzw. verringert, dass diese mit einer Beschichtung versehen werden. Die Beschichtung kann im einfachsten Falle nach Art eines Lacks auf die Oberfläche aufgetragen werden dabei findet eine solche Beschichtung Verwendung, die niedrig energene Eigenschaften aufweist und dadurch ein Benetzen der Oberflächen mit Flüssigkeit und darin enthaltenen Zusätzen verhindert, indem die Flüssigkeit köaguliert also zusammen mit den darin gebundenen Zusätzen Tropfen oder dergleichen bildet, die von der beschichteten Oberfläche bzw. der Oberseite der Beschichtung abperlen.The adhesive properties of the surfaces in question are preferred eliminated or reduced by providing them with a coating. In the simplest case, the coating can be applied to the surface in the manner of a lacquer such a coating is used that is low has energetic properties and thereby wetting the surfaces Prevents liquid and additives contained therein by coagulating the liquid thus forms drops or the like together with the additives bound therein roll off the coated surface or top of the coating.

Vorzugsweise weist die Mikrorauhigkeit eine Struktur auf, die aus feinen Mikronoppen gebildet wird. Diese Struktur führt zu einer hydrophoben Oberfläche, wie sie von Lotusblumenblättern bekannt ist. Diese Oberfläche lässt sich nicht benetzen. Sie wird nach jedem Befeuchten sofort wieder trocken und bleibt auch sauber, da die Flüssigkeit, insbesondere Wasser, sofort von der Oberfläche abperlt und dabei Schmutzteilchen mitnimmt, die somit nicht auf der Oberfläche festhaften können.The micro-roughness preferably has a structure which consists of fine micro-knobs is formed. This structure leads to a hydrophobic surface like that of Lotus petals is known. This surface cannot be wetted. she will immediately dry after each moistening and also stays clean because the liquid, especially water, immediately rolls off the surface and dirt particles takes with them, which cannot stick to the surface.
Die Beschichtung wird nach Art eines Lackes gebildet, wozu die Beschichtung im einfachsten Fall durch Lackieren auf die Oberfläche aufgebracht wird. Für die Beschichtung bzw. als Lack eignet sich ein polymerhaltiges Material bzw. ein Polymer. Insbesondere findet eine Beschichtung bzw. ein Lack auf Silikonbasis Verwendung. Auf diese Weise lässt sich einfach und wirksam eine dauerhafte Beschichtung der Oberfläche bilden, die zum von Lotusblättern bekannten Effekt des Abperlens von Wasser oder sonstigen Flüssigkeiten einschließlich darin enthaltener Zusätze oder Verschmutzungen führt.The coating is formed like a varnish, which is why the coating in simplest case is applied to the surface by painting. For the A polymer-containing material or a polymer is suitable for coating or as a lacquer. In particular, a coating or varnish based on silicone is used. On this way, a permanent coating of the surface can be easily and effectively form the effect of water or water pearls known from lotus leaves other liquids including additives or dirt contained therein leads.

Dabei handelt es sich um eine Vorrichtung, die die Wäschestücke vor allem nach dem Waschen entwässert, nämlich einen Großteil der Flüssigkeit aus dem Wäschestücken entfernt. Beispielsweise kann es sich hierbei um eine Entwässerungspresse handeln, bei der aus der in einem Aufnahmebehälter sich befindenden Wäsche durch einen Pressstempel die Flüssigkeit größtenteils aus den Wäschestücken herausgepresst wird. Hierbei sind mindestens die mit den Wäschestücken in Berührung kommenden Oberflächen des Behälters und gegebenenfalls auch des Pressstempels so behandelt, dass sie verringerte Hafteigenschaften aufweisen. Unter dem Begriff "verringerte Hafteigenschaft" ist in diesem Zusammenhang zu verstehen, dass die so ausgebildeten oder behandelten Oberflächen nicht oder nicht nennenswerte Umfange zum Anhaften von irgendwelchen Verunreinigungen neigen, sich also auf die Dauer keine ungewünschten Beläge auf mindestens den mit den Wäschestücken in Berührung kommenden Teilen der Vorrichtung bilden können.A device for solving the above-mentioned object has the features of Claim 7 on. This is a device that pre-sets the laundry items drained everything after washing, namely a large part of the liquid from the Items removed. For example, this can be a dewatering press act with the laundry in a receptacle most of the liquid from the laundry by means of a press ram is pressed out. At least those are in contact with the items of laundry coming surfaces of the container and, if applicable, also of the press ram treated that they have reduced adhesive properties. Under the term In this context, "reduced adhesive property" means that the so trained or treated surfaces not or not significant extent tend to stick to any contaminants, so in the long run none unwanted coverings on at least those in contact with the items of laundry can form upcoming parts of the device.

But also bridges between successive mangle troughs of a plurality of mangle rolls Trough shortages are preferably designed or treated so that their with the Garments in contact with surfaces have no noteworthy adhesive properties exhibit.
Die verringerten Hafteigenschaften der vorstehend beschriebenen Vorrichtungen werden bevorzugt erreicht durch eine Oberfläche, die die Eigenschaften von Lotusblumenblättern aufweist. Demzufolge ist die Oberfläche bzw. Plättfläche mit einer Mikrostruktur, insbesondere einer Mikronoppen aufweisenden Mikrorauhigkeit, versehen.The reduced adhesive properties of the devices described above will preferably achieved by a surface that has the properties of lotus petals having. As a result, the surface or plate surface has a microstructure, in particular a micro roughness having micro knobs.
Entweder ist die Oberfläche der Mangelmulde, der Trommel, des Vorratsbehälters, des Aufnahmebehälters und/oder des Pressstempels zur Bildung der Vorrichtungen nach den Ansprüchen 7-9 selbst so ausgebildet, dass Mikrostrukturen, insbesondere Mikronoppen auf den mindestens mit den Wäschestücken in Kontakt kommenden Oberflächen vorhanden sind. Üblicherweise werden jedoch die Oberflächen der vorstehend genannten Komponenten der Vorrichtungen mit einer Beschichtung versehen, die auf ihrer freiliegenden, den Wäschestücken zugewandten Kontaktfläche mit Mikrostrukturen bzw. Mikronoppen versehen ist. Eine solche Beschichtung kann aus einem Lack oder einem lackähnlichen Material gebildet sein. Die Beschichtung ist ganz oder teilweise aus mindestens einem Polymer bzw. Silikon gebildet. Das Material der Beschichtung ist dabei so gewählt, dass dieses zumindest abriebfest ist. Insbesondere bei Mangeln und Waschmaschinen wird ein Material für die Beschichtung gebildet, dass dem bei diesen Vorrichtungen vorherrschenden Temperaturen zuverlässig standhält.Either the surface of the trough, the drum, the storage container, the Receiving container and / or the press ram to form the devices according to the Claims 7-9 themselves designed so that microstructures, in particular micro-knobs on the surfaces that come into contact with the items of laundry at least available. Usually, however, the surfaces of the above Components of the devices provided with a coating on their exposed contact surface facing the laundry items with microstructures or Microns is provided. Such a coating can consist of a paint or a lacquer-like material be formed. The coating is completely or partially out formed at least one polymer or silicone. The material of the coating is included chosen so that it is at least abrasion-resistant. Especially with shortages and Washing machines are made of a material for the coating, that of these Device reliably withstands prevailing temperatures.
Nachfolgend werden bevorzugte Beispiele von Vorrichtungen zu Wäschereizwecken erläutert, die nach dem erfindungsgemäßen Verfahren hergestellt sind. The following are preferred examples of devices for laundry purposes explained, which are prepared by the inventive method.
Eine als Waschmaschine ausgebildete Vorrichtung zu einer Nassbehandlung von Wäschestücken verfügt über eine drehbare Trommel in der bei gewerblichen Waschmaschinen die Vorwäsche, Nachwäsche, das Spülen gegebenenfalls eine Ausrüstung der Wäschestücke erfolgen. Des Weiteren verfügt die Waschmaschine über mindestens einen Vorratsbehälter für Behandlungsflüssigkeit. Der Vorratsbehälter, auch Tank genannt, dient auch als Zwischenspeicher für die Flüssigkeit.A device designed as a washing machine for wet treatment of Laundry items has a rotating drum in the commercial Wash the pre-wash, post-wash, rinse if necessary The laundry items are equipped. Furthermore, the washing machine has at least one reservoir for treatment liquid. The reservoir, too Called the tank, it also serves as a temporary storage for the liquid.
Damit bei diesen Waschmaschinen an der Oberfläche der Waschtrommel und der Tanks keine Verunreinigungen, die beispielsweise aus Zusätzen in den Flüssigkeiten, und zwar sowohl Waschflüssigkeiten als auch Spülflüssigkeiten und Ausrüstflüssigkeiten, enthalten sein können, festhaften, sind diese so ausgebildet, dass sie mindestens verringerte Hafteigenschaften aufweisen, vorzugsweise überhaupt keine Haftung zulassen. Zumindest sind so solche Oberflächen der Trommel und/oder der Tanks gebildet, die mit Flüssigkeit bzw. Wäschestücken in Berührung.So with these washing machines on the surface of the washing drum and the tanks no impurities, for example from additives in the liquids, namely contain both washing liquids and rinsing liquids and finishing liquids may be adherent, they are designed so that they are at least reduced Have adhesive properties, preferably allow no liability at all. At least such surfaces of the drum and / or tanks are formed that with Liquid or items of laundry in contact.
Beim hier beschriebenen Beispiel werden die betreffenden Oberflächen haftunfähig gemacht durch eine zusätzliche Beschichtung. Bei dieser Beschichtung kann es sich um Lack oder eine Substanz handeln, die wie Lack auf die unbeschichtete Oberfläche der Trommel bzw. der Tanks aufgebracht wird. Diese unbeschichtete Oberfläche ist gebildet aus üblichen Materialien für solche Waschmaschinen, und zwar Stahl, insbesondere Edelstahl bzw. rostfreier Stahl.In the example described here, the surfaces concerned become incapable of adhesion made by an additional coating. This coating can be Paint or a substance act like paint on the uncoated surface of the Drum or the tanks is applied. This uncoated surface is formed made of common materials for such washing machines, namely steel, in particular Stainless steel or stainless steel.
Die Beschichtung ist gebildet aus einem Lack oder einer sonstigen Substanz, die ganz oder zumindest teilweise aus einem Polymer besteht, insbesondere Silikon. Diese Beschichtung weist an ihren freien Flächen eine Oberfläche mit einer gezielten Rauhigkeit, und zwar einer Mikrorauhigkeit auf. Diese Mikrorauhigkeit wird durch eine feine Mikronoppen aufweisende Mikrostruktur gebildet, wodurch die Oberfläche von Lotusblumenblätten nachgeahmt wird und die Struktur der freiliegenden Flächen der Beschichtung die Eingenschaften dieser Lostusblumenblätter aufweist. In Folge der Mikroporen kann diese Oberfläche als nichthaltende Oberfläche bezeichnet werden, die dazu führt, dass Flüssigkeiten die Oberflächen nicht benetzen, sondern sich auf Grund ihrer Eigenspannung zusammenziehen zu Flüssigkeitstropfen, die von der Beschichtung abperlen und dabei Verunreinigungen, insbesondere durch in der Flüssigkeit enthaltenden Zusatzstoffe, mitreißen. Die mit der Beschichtung versehene Trommel bleibt dadurch an den beschichteten Flächen, nämlich solchen, die mit der zu waschenden oder in sonstiger Weise zu behandelnden Wäschestücken in Berührung kommen, frei von Ablagerungen und stets sauber. Ebenso verhält es sich bei den Tanks die insbesondere an der Innenwandung, wo zumindest die erfindungsgemäße Beschichtung vorhanden ist, frei von Ablagerungen bleiben.The coating is formed from a varnish or other substance that is entirely or at least partially consists of a polymer, in particular silicone. This Coating has a targeted surface on its free surfaces Roughness, namely a microroughness. This micro roughness is caused by a fine micro-nubs microstructure is formed, whereby the surface of Lotus flower petals are mimicked and the structure of the exposed areas of the Coating has the properties of these lostus petals. As a result of Micropores, this surface can be referred to as a non-holding surface leads to the fact that liquids do not wet the surfaces, but become aground their residual stress contract to form liquid drops from the coating roll off and contaminants, especially from in the liquid containing additives. The drum with the coating remains thereby on the coated surfaces, namely those which are to be washed or items of laundry to be treated in any other way come free of Deposits and always clean. The same applies to the tanks in particular on the inner wall, where at least the coating according to the invention is present, remain free of deposits.
Weiterhin können Vorrichtungen zum Entwässern von Wäsche mit einer nichthaftenden Beschichtung versehen sein. Im Falle einer Entwässerungspresse, die aus einem Aufnahmebehälter für die von einem Großteil der Flüssigkeit (gebundene Flotte) zu befreienden Wäsche und einen Pressstempel aufweisent, sind mindestens die mit den Wäschenstücken in Berührung kommenden Oberflächen des Aufnahmebehälters und des Pressstempels mit einer antihaftenden Beschichtung versehen. Diese Beschichtung ist vorzugsweise aus dem gleichen Material gebildet und weist die gleichen Eigenschaften auf, wie im Zusammenhang mit der Beschichtung für die Trommel und die Tanks der Waschmaschine nach dem ersten Ausführungsbeispiel der Erfindung beschrieben worden ist.Furthermore, devices for dewatering laundry with a non-adhesive Coating should be provided. In the case of a dewatering press consisting of a Containers for the bulk of the liquid (bound liquor) too liberating laundry and a stamp, at least those with the Items of laundry in contact with surfaces of the receptacle and of the press stamp with an anti-stick coating. This coating is preferably formed from the same material and has the same properties on how in connection with the coating for the drum and tanks of the Washing machine according to the first embodiment of the invention described has been.
Auch bei einer Vorrichtung zum Glätten von Wäschestücken, insbesondere einer Muldenmangel, kann eine nichthaftende Eigenschaft aufweisende Beschichtung vorhanden sein. Diese Beschichtung befindet sich zweckmäßiger Weise auf einer zu einer drehenden Mangelwalze weisenden Innenseite einer beheizbaren, halbkreisförmigen Mangelmulde, nämlich der sogenannten Plättfläche. Plättfläche ist vorzugsweise vollflächig antihaftend gemacht durch eine entsprechende Beschichtung der vorstehend beschriebenen Art und Eigenschaften. Insbesondere ist der Einlaufbereich der Mangelmulde nichthaftend ausgebildet, weil hier die Wäschestücke noch eine verhältnismäßig große Feuchte aufweisen. Ebenso ist es denkbar, Brücken zwischen aufeinanderfolgenden Mangelmulden von Muldenmangeln mit mehreren Mangelwalzen mit einer nichthaftenden Beschichtung zu versehen.Even with a device for smoothing laundry, in particular one Trough deficiency, a non-adhesive coating can be present his. This coating is expediently on one at a time rotating ironer-facing inside of a heatable, semicircular Lack trough, namely the so-called flat surface. Flattening surface is preferred made completely non-stick by a corresponding coating of the above described type and properties. In particular, the inlet area is the Deficiency tray non-adherent, because here the laundry items one more have relatively high humidity. It is also conceivable to build bridges between successive troughs of trough ironers with several ironer rollers to be provided with a non-stick coating.
Die nichthaftende Beschichtung wird verfahrensmäßig nach der Herstellung der nichthaftenden Eigenschaften aufweisenden vorstehend beschriebenen Komponenten der Waschmaschine, Entwässerungspresse und/oder Muldenmangel auf die unbehandelte, glatte Metalloberfläche aufgebracht, und zwar entweder durch Spritzen, Streichen oder auch Gießen. Zumindest werden diejenigen Teile der genannten Vorrichtung beschichtet, die mit den Wäschestücken in Berührung kommen, damit die Wäschestücke vor Ablagerungen geschützt sind. Es ist jedoch auch denkbar, übrige Oberflächen oder Teile der genannten Vorrichtung zu beschichten, damit diese auch frei von irgendwelchen Ablagerungen bleiben, die die Oberflächen in irgendeiner Weise angreifen könnten.The non-stick coating is procedurally after the production of the Components described above non-adhesive properties the washing machine, dewatering press and / or trough lack on the untreated, smooth metal surface applied, either by spraying, Painting or watering. At least those parts of the above Coated device that come into contact with the laundry, so that the Items of laundry are protected from deposits. However, it is also conceivable, others To coat surfaces or parts of the device mentioned so that it is also free of any debris that remain on the surfaces in any way could attack.
Die Beschichtung aus insbesondere Silikon oder einem anderen Polymer, insbesondere einem Polymer, indem die Wasserstoffatome ganz oder teilweise durch Fluoratome ersetzt sind, ist so gewählt, dass sie abriebfest ist und insbesondere bei Muldenmangeln auch temperaturbeständig ist, nämlich die Temperaturen der beheizten Mangelmulde standhält.The coating, in particular silicone or another polymer, in particular a polymer, in which the hydrogen atoms are wholly or partly by fluorine atoms are selected so that they are resistant to abrasion and especially in the case of trough defects is also temperature-resistant, namely the temperatures of the heated ironer withstand.
Nach der Beschichtung der betreffenden Oberflächen der Vorrichtungen sind mindestens die mit den Wäschestücken in Kontakt kommenden Flächen der Vorrichtungen mit einer Mikroporenstruktur ähnlich derjenigen von Lotusblumenblättern versehen. Bei dieser Struktur die hydrophobe und/oder niedrigenergene Eigenschaften aufweist, findet keine Benetzung für die Flüssigkeiten statt. Vielmehr werden die Flüssigkeiten zur Tropfenbildung angeregt. Die Tropfen perlen von den Flächen ab, wodurch eine Ableitung der in den Flüssigkeiten enthaltenen Zusätze stattfindet, aber auch sonstige Verunreinigungen, die in den Flüssigkeiten nicht gebunden sind, mitgerissen werden und dadurch eine ständige Selbstreinigung der betreffenden Komponenten der Waschmaschine, Entwässerungspresse, bzw. Muldenmangel erfolgt.After coating the relevant surfaces of the devices, at least the surfaces of the devices coming into contact with the laundry items with a Microporous structure similar to that of lotus petals. At this There is no structure that has hydrophobic and / or low-energy properties Wetting for the liquids instead. Rather, the liquids become Drip formation stimulated. The drops roll off the surfaces, causing a drain the additives contained in the liquids take place, but also others Impurities that are not bound in the liquids are entrained and thereby a constant self-cleaning of the relevant components of the Washing machine, dewatering press, or trough lack.
Es ist auch denkbar, die Erfindung, insbesondere das erfindungsgemäße Verfahren, bei anderen Wäschereimaschinen, und zwar insbesondere Waschschleudermaschinen und/oder Trocknern, einzusetzen. Hier vor allem auch Trommeln ganz oder nur bezüglich ihrer mit Wäschestücken in Kontakt kommenden Oberflächen mit nichthaltenden Eigenschaften versehen, so das sie den weiter oben beschriebenen Lotusblumenblatteffekt und die daraus resultierenden Wirkungen aufweisen.It is also conceivable to include the invention, in particular the method according to the invention other laundry machines, in particular washer extractors and / or dryers.
