Definitions

  • the invention relates to a device for the biocidal treatment of laundry in a washing machine.
  • biocidal substances ie those which kill or at least inhibit growth on microorganisms such as bacteria, viruses, fungi and / or spores
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the hollow body may consist of a detergent-resistant plastic.
  • the hollow body comprises an inner shell and an outer shell.
  • the outer shell can consist of a laundry-preserving, soft or elastic material which, moreover, has a pleasing color and haptic appeal.
  • 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.
  • 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.
  • 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.
  • the hollow body is a hollow sphere.
  • 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.
  • 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.
  • the biocidal substance may include quaternary ammonium compounds, triclosan, isothiazolines, antibiotics, chitosan, or mixtures thereof.
  • the biocidal substance may comprise quaternary ammonium compounds, triclosan, isothiazolines, antibiotics, chitosan, or mixtures thereof.
  • the use of a mixture of different biocidal substances is possible.
  • 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 may, for example, be between 1 ⁇ g / l and 10 mg / l of water.
  • biocidal substances come into consideration, which are released in contact with an aqueous medium in an effective, for human metabolism but harmless lent concentration.
  • 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. 1 shows a device in the form of a hollow sphere
  • FIG. 1 is a plan view of the hollow sphere in Fig. 1,
  • Fig. 4 is a section along the line D-D in Fig. 2nd
  • 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 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.
  • the carrier body 3 may be dispensed with if the biocidal substance is e.g. is a granulated or compact, sparingly soluble metal salt.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
