Description

Vorrichtung zur bioziden Behandlung von Wäsche Device for the biocidal treatment of laundry
Die Erfindung betrifft eine Vorrichtung zur bioziden Behandlung von Wäsche in einer Waschmaschine.The invention relates to a device for the biocidal treatment of laundry in a washing machine.
Zwar sind zahlreiche biozid wirkende Substanzen, also sol- che, die auf Mikroorganismen wie Bakterien, Viren, Pilze und/oder Sporen abtötend oder mindestens wachstumshemmend wirken, bekannt. Geeignete Substanzen, d.h. solche, die in passender Dosierung biozid wirksam, jedoch für den menschlichen Organismus und insbesondere den menschlichen Stoff - Wechsel (Metabolismus) zumindest weitestgehend unschädlich sind, können z.B. mittels einer Dosiervorrichtung dem Waschmittel zugegeben oder direkt in die Waschtrommel bei deren Beladung mit Wäsche eingegeben werden. Eine biozide Behandlung jeder Wäschecharge auf diesem Weg ist sowohl um- ständlich als auch mit dem Risiko von Unter- oder Überdosierungen behaftet.It is true that numerous biocidal substances, ie those which kill or at least inhibit growth on microorganisms such as bacteria, viruses, fungi and / or spores, are known. Suitable substances, i. those which are biocidally effective at the appropriate dosage but at least largely harmless to the human organism and in particular to the human metabolism, may e.g. be added by means of a metering device to the detergent or be entered directly into the washing drum in the loading of laundry. Biocide treatment of each wash batch in this way is both cumbersome and carries the risk of under- or overdosing.
Der Erfindung liegt die Aufgabe zugrunde, eine einfach zu handhabende Vorrichtung zur bioziden Behandlung von Wäsche in einer Waschmaschine, insbesondere einer Haushaltswaschmaschine, zu schaffen.The invention has for its object to provide an easy-to-use device for the biocidal treatment of laundry in a washing machine, in particular a household washing machine.
Diese Aufgabe ist erfindungsgemäß dadurch gelöst, dass eine biozide Substanz in einem Hohlkörper eingeschlossen ist, dessen Schale Öffnungen für den Durchtritt der Wasch- und Spülflotten hat.This object is inventively achieved in that a biocidal substance is enclosed in a hollow body whose shell has openings for the passage of the washing and rinsing liquors.
Der Hohlkörper enthält eine biozide Substanz, deren Art, Zusammensetzung und ggf. Trägerstruktur herstellerseitig so ausgewählt ist, dass sie in ein wässriges Medium, also die Wasch- und/oder Spülflotten der Waschmaschine in einer wirksamen, jedoch für Menschen unschädlichen Konzentration kontinuierlich freigesetzt wird. Der Benutzer braucht deshalb diesen Hohlkörper nur zusammen mit der Wäsche in die Waschtrommel zu geben. Die biozide Substanz und/oder ihre Trägerstruktur können insbesondere so gewählt sein, dass sie für sehr viele, z.B. über hundert Waschgänge wirksam bleiben.The hollow body contains a biocidal substance, the type, composition and optionally carrier structure is selected by the manufacturer so that they in an aqueous medium, ie the washing and / or rinsing liquors of the washing machine is continuously released in an effective, but harmless concentration for humans. Therefore, the user needs to give this hollow body only together with the laundry in the washing drum. The biocidal substance and / or its carrier structure may in particular be chosen so that they remain effective for very many, eg over a hundred washes.
Der Hohlkörper besteht vorzugsweise aus zwei miteinander verrasteten Halbschalen, die nach Einbringung der bioziden Substanz herstellerseitig unlösbar miteinander verrastet werden.The hollow body preferably consists of two half-shells locked together, which after insertion of the biocidal substance are irreversibly latched together by the manufacturer.
Insbesondere kann der Hohlkörper aus einem waschmittelbeständigen Kunststoff bestehen.In particular, the hollow body may consist of a detergent-resistant plastic.
Vorzugsweise umfasst der Hohlkörper eine Innenschale und eine Außenschale. Dies hat den Vorteil, dass die Außenscha- Ie aus einem wäscheschonendem, weichen oder elastischen Material bestehen kann, das zudem farblich und haptisch ansprechend gestaltet ist.Preferably, the hollow body comprises an inner shell and an outer shell. This has the advantage that the outer shell can consist of a laundry-preserving, soft or elastic material which, moreover, has a pleasing color and haptic appeal.
In dieser Ausführungsform kann die Innenschale aus einem die mechanische Festigkeit gewährleistenden Kunststoff wie glasfaserverstärktem Polypropylen und die Außenschale aus einem thermoplastischen Elastomeren sein.In this embodiment, the inner shell may be made of a mechanical strength ensuring plastic such as glass fiber reinforced polypropylene and the outer shell of a thermoplastic elastomer.
Die Anordnung, die Zahl und der Querschnitt der Öffnungen in der Hohlkörperschale beeinflussen die Konzentration der bioziden Substanz in den Wasch- und/oder Spülflotten. Zweckmäßig können die Öffnungen in der Hohlkörperschale aus zwei einander gegenüberliegenden Sätzen von Löchern, mit Durchmessern zwischen 0,5 mm und 5 mm, bestehen, wobei die- se zwei Löchersätze einander zweckmäßigerweise gegenüberliegen. In die Hohlkörperschale kann an mindestens einer Stelle ein Indikator eingebettet sein, der durch Farbumschlag das Ende der Nutzungsdauer der Vorrichtung anzeigt. Das ist vor al- lern dann sinnvoll, wenn die Vorrichtung durch geeignete Wahl der bioziden Substanz für eine sehr große Zahl, z.B. 100 Wäschechargen verwendet werden kann. Die Nutzungsdauer kann in einem solchen Fall auch durch mechanischen Verschleiß des Hohlkörpers begrenzt sein.The arrangement, the number and the cross section of the openings in the hollow body shell influence the concentration of the biocidal substance in the washing and / or rinsing liquors. Suitably, the openings in the hollow body shell of two opposite sets of holes, with diameters between 0.5 mm and 5 mm, consist, these two holes sets expediently opposite each other. An indicator may be embedded in the hollow body shell at at least one point, which indicates by color change the end of the useful life of the device. This is particularly useful if the device can be used by a suitable choice of the biocidal substance for a very large number, eg 100 batches of laundry. The service life can be limited in such a case by mechanical wear of the hollow body.
Besonders bevorzugt ist der Hohlkörper eine Hohlkugel .Particularly preferably, the hollow body is a hollow sphere.
Die biozide Substanz kann aus nano-skaligen Teilchen auf einer Trägerstruktur oder in diese eingebettet bestehen. Geeignete organische oder anorganische , poröse oder was- serpermeable Trägermaterialien sind dem Fachmann bekannt.The biocidal substance may consist of nanoscale particles embedded in or embedded in a support structure. Suitable organic or inorganic, porous or water-permeable carrier materials are known to the person skilled in the art.
Bevorzugt umfasst die biozide Substanz Metallionen. Dabei kann es sich um Ionen mindestens eines der Metalle Ag, Cu, Zn, Au, Ir, Pd, Ti, Al und Sn handeln.Preferably, the biocidal substance comprises metal ions. These may be ions of at least one of the metals Ag, Cu, Zn, Au, Ir, Pd, Ti, Al and Sn.
Alternativ kann die biozide Substanz quartäre Ammoniumverbindungen, Triclosan, Isothiazoline, Antibiotika, Chitosan oder Mischungen hiervon umfassen.Alternatively, the biocidal substance may include quaternary ammonium compounds, triclosan, isothiazolines, antibiotics, chitosan, or mixtures thereof.
Nach einer anderen Ausführungsform kann die biozide Substanz quartäre Ammoniumverbindungen, Triclosan, Isothiazoline, Antibiotika, Chitosan oder Mischungen hiervon umfassen.In another embodiment, the biocidal substance may comprise quaternary ammonium compounds, triclosan, isothiazolines, antibiotics, chitosan, or mixtures thereof.
Selbstverständlich ist auch die Verwendung eines Gemisches unterschiedlicher biozider Substanzen möglich. Abhängig von der getroffenen Wahl, wird durch die Zahl und den Querschnitt der Löcher, die Art des Trägermaterials und die Menge dessen Dotierung mit der bioziden Substanz, alternativ deren Granulierung und Menge, die durchschnittliche wirksame Konzentration eingestellt. Sie kann in diesem Sinn z.B. zwischen 1 μg/1 und 10 mg/1 Wasser liegen.Of course, the use of a mixture of different biocidal substances is possible. Depending on the choice made, the number and cross section of the holes, the type of support material and the amount of its doping with the biocidal substance, alternatively their granulation and amount, the average effective concentration set. In this sense, it may, for example, be between 1 μg / l and 10 mg / l of water.
Grundsätzlich kommen alle bioziden Substanzen in Betracht, die im Kontakt mit einem wässrigen Medium in einer wirksamen, für den menschlichen Metabolismus jedoch unschäd- liehen Konzentration freigesetzt werden. Besonders bevorzugt sind biozide Substanzen, die nicht nur während des Waschvorganges wirksam sind sondern zu einer Imprägnierung der Wäsche führen, so dass die Wäsche nach dem Waschen für längere Zeit biozid ausgerüstet ist, d.h. die Ansiedelung und/oder die Vermehrung von Mikroorganismen erheblich vermindert oder sogar für einige Zeit völlig unterdrückt wird. Diese Wirkung wurde vor allem bei dem oben genannten Ein- satz von Metallionen, insbesondere von Silberionen, quantitativ nachgewiesen.In principle, all biocidal substances come into consideration, which are released in contact with an aqueous medium in an effective, for human metabolism but harmless lent concentration. Particularly preferred are biocidal substances which are effective not only during the washing process but lead to an impregnation of the laundry, so that the laundry is biocidically equipped for a long time after washing, i. the settlement and / or multiplication of microorganisms is significantly reduced or even completely suppressed for some time. This effect was demonstrated quantitatively, above all in the abovementioned use of metal ions, in particular silver ions.

Fig. 4 einen Schnitt längs der Linie D-D in Fig. 2.Fig. 4 is a section along the line D-D in Fig. 2nd
Fig. 5 die Einzelheit in Fig. 3 in vergrößertem Maßstab. Die in Fig. 1 dargestellte Hohlkugel besteht aus einer oberen Halbschale 1 und einer unteren Halbschale 2, die miteinander verrastet und gelocht sind. Der Außendurchmesser der Hohlkugel kann z.B. bei 50 mm liegen. Fig. 2 zeigt eine Aufsicht auf die Hohlkugel, in erster Linie zur Veranschaulichung der Lage der Schnittlinien B-B und D-D in den nachfolgenden Figuren.Fig. 5 shows the detail in Fig. 3 on an enlarged scale. The hollow sphere shown in Fig. 1 consists of an upper half-shell 1 and a lower half-shell 2, which are locked together and perforated. The outer diameter of the hollow sphere can be, for example, 50 mm. Fig. 2 shows a plan view of the hollow sphere, primarily to illustrate the position of the section lines BB and DD in the following figures.
Fig. 3 verdeutlicht, dass im Inneren der Hohlkugel 1.2 ein hier beispielhaft als Würfel dargestellter Trägerkörper 3 eingeschlossen ist, der die biozide Substanz enthält. Der Trägerkörper 3 kann z.B. ein Fasergebilde in Form eines Fließes oder eines mehrlagigen Gewirks oder Gewebes sein, das mit der bioziden Substanz dotiert ist. Besonders bewährt haben sich silberhaltige cellulosische Fasern mit io- nentauschen-den Eigenschaften. Als Trägermaterialien kommen auch dotierte poröse Polymere, Polyurethan, Aktivkohle, Zeolithe, Keramiken und dergleichen in Betracht.Fig. 3 illustrates that in the interior of the hollow sphere 1.2 a here exemplified as a cube carrier body 3 is included, which contains the biocidal substance. The carrier body 3 may e.g. a fibrous structure in the form of a flow or a multi-layered knit or fabric doped with the biocidal substance. Silver-containing cellulosic fibers with ion exchange properties have proved particularly useful. Suitable support materials are also doped porous polymers, polyurethane, activated carbon, zeolites, ceramics and the like.
Auf den Trägerkörper 3 kann verzichtet werden, wenn die biozide Substanz z.B. ein granuliertes oder kompaktes, schwer lösliches Metallsalz ist.The carrier body 3 may be dispensed with if the biocidal substance is e.g. is a granulated or compact, sparingly soluble metal salt.
Die Fig. 1 und Fig. 3 zeigen weiter, dass die obere Halbschale 1 mit einem ersten Satz von Löchern 4 und die untere Halbschale 2 mit einem zweiten Satz von Löchern 4 versehen ist.FIGS. 1 and 3 further show that the upper half shell 1 is provided with a first set of holes 4 and the lower half shell 2 is provided with a second set of holes 4.
Beide Halbschalen sind, wie die Fig. 3 und 4 hzeigen, zweischichtig. Die jeweiligen Innenschalen 1.1, 2.1 bestehen aus glasfaserverstärktem Polypropylen. Die Außenschalen 1.2, 2.2 bestehen aus einem thermoplastischen Elastomeren und sind durch Anschmelzung oder in anderer geeigneter Wei- se mit den jeweiligen Innenschalen 1.1, 2.1 einstückig verbunden .Both half-shells are, as shown in FIGS. 3 and 4 show, in two layers. The respective inner shells 1.1, 2.1 are made of glass fiber reinforced polypropylene. The outer shells 1.2, 2.2 consist of a thermoplastic elastomer and are integrally connected by fusion or in another suitable manner with the respective inner shells 1.1, 2.1.
Aus optischen Gründen sind die Löcher 4 gestuft ausgebildet, d.h. die Lochquerschnitte in den jeweiligen Außenscha- len 1.2, 2,2sind etwas größer als die Querschnitte der korrespondierenden Löcher in den jeweiligen Innenschalen 1.1, 2.1. Der Lochdurchmesser liegt in dieser Ausführungsform bei etwas mehr als einem Millimeter.For optical reasons, the holes 4 are stepped, that is, the hole cross sections in the respective outer shells 1.2, 2.2 are slightly larger than the cross sections of the corresponding holes in the respective inner shells 1.1, 2.1. The hole diameter is in this embodiment at just over one millimeter.
Die obere Innenschale 1.1 und die untere Innenschale 2.1 sind gemäß den Fig. 3 bis 5 umlaufend ähnlich einer Nut- und-Feder-Verbindung praktisch unlösbar miteinander verrastet . Zu diesem Zweck ist die obere Innenschale 1.1 mit zahlreichen Stegen 1.1.1 versehen, die ihr eine hohe Steifigkeit verleihen, so dass die Hohlkugel nur unter Zerstö- rung geöffnet werden kann.The upper inner shell 1.1 and the lower inner shell 2.1 are locked in accordance with FIGS. 3 to 5 circumferentially similar to a tongue and groove connection virtually insoluble with each other. For this purpose, the upper inner shell 1.1 is provided with numerous webs 1.1.1, which give it a high rigidity, so that the hollow sphere can only be opened with destruction.
Eine oder beide Halbschalen können eine z.B. den Platz (je) eines Loches einnehmende Indikatorsubstanz (nicht dargestellt) tragen, die z.B. durch Farbwechsel, dessen Auftre- ten von der Anzahl, der Dauer und den Waschflottentemperaturen abhängt, anzeigt, dass die Wirksamkeit der bioziden Substanz sich dem Ende zuneigt. One or both half-shells may have a e.g. carry the place (each) hole occupying indicator substance (not shown), e.g. Color change, which depends on the number, duration and wash liquor temperatures, indicates that the efficacy of the biocidal substance is nearing completion.
