Definitions

  • the invention relates to a device for the precipitation of lime from water for use within a dishwasher according to the preamble of claim 1.
  • the object is therefore to provide a device for precipitating the lime from the water in a dishwasher, which has a good effect and does not pollute the waste water in any way.
  • Figure 1 is a schematic side view of a device according to the invention.
  • Figure 2 is a bottom view of the bottom of the device shown in Figure 1; and Figure 3 is a top view of the top of the container shown in Figure 1.
  • the container shown in Figure 1 has a substantially cylindrical housing 2, which preferably consists of a stainless steel mesh that is supported by a plastic frame. Care must be taken to use a heat-resistant plastic that can withstand the temperatures that occur in a dishwasher.
  • the cylindrical housing 2 has an opening which is closed with the container lid 3.
  • the container bottom has a reinforcing ring and reinforcing webs, which are also made of heat-resistant plastic, and spacer cones 6, which are provided so that the container bottom does not lie directly on the dishes to be cleaned.
  • the height of the housing 2 is approximately 50 to 100 mm, the diameter is 30 to 50 mm.
  • the top 4 of the housing is flared, as shown in Figures 1 and 3.
  • a reinforcing ring and web which is also made of heat-resistant plastic, and a retaining bracket 7, via which the device can be hung on a suitable suspension device within the dishwasher.
  • the housing 2 and the container bottom are closed on all sides by a stainless steel screen mesh 2, which has a mesh size between 0.2 and 0.8 mm, as a result of which the water in the dishwasher can enter and exit.
  • the device is completely or partially filled with a material described in technical terms as catalyst granules.
  • This catalyst granulate is an ion exchange material which is weakly acidic and has functional carboxylate groups (COO " ) on its surface, which in turn carry counterions, namely Ca 2+ ions.
  • This material is described in detail in the document mentioned in the introduction to the description described why special configurations of the material should not be discussed further here.
  • the effect of the material is that it binds the lime physically dissolved in the water, creating lime agglomerations that are washed off the surface in larger particles. This means that the physically dissolved lime crystals cannot settle homogeneously on the surface of the dishwasher and on the dishes and thus form the unwanted lime film, but are flushed out with the waste water.
  • the described device is introduced into the interior of a dishwasher before the washing process and, for example, placed or placed in the baskets available for glasses or cups. Here you can use the retaining web 5 or the bracket 7.
  • the water that has entered the dishwasher through a tap is sprayed under pressure using nozzles in the rotating arms of the machine.
  • the device according to the invention is repeatedly flowed through by the water.
  • the water is mixed with detergent and heated.
  • the so-called seed crystals form on the surface of the catalyst granules and are rinsed out after reaching a certain size.
  • the regeneration of the catalyst granules takes place in a manner known per se. No salt is necessary for this and the catalyst granules can be used as often as desired.
  • a soft material for example a net or a type of stocking, is selected instead of the housing 2, as a result of which the access of the water into the interior of the container is ensured. Damage to the dishes is further avoided with this procedure.
  • the soft container can have a hanging hook for hanging in the interior of the dishwasher.

Abstract

L'invention concerne un dispositif servant à la précipitation du calcaire de l'eau dans des lave-vaisselle. De tels dispositifs connus utilisent des substances chimiques entraînant souvent une charge en matières polluantes des eaux usées. L'invention vise à fournir un dispositif pour la précipitation du calcaire de l'eau à l'intérieur d'un lave-vaisselle, qui soit efficace et n'entraîne pas la pollution des eaux usées. A cet effet, le dispositif selon l'invention comporte un contenant pouvant être placé à l'intérieur du lave-vaisselle, pouvant être traversé par l'eau de lavage du lave-vaisselle et contenant une substance échangeuse d'ions qui présente, à sa surface, des groupes carboxylate fonctionnels (COO-).
