Definitions

  • the invention relates to a dishwasher with a metering device for the addition of additives in the washing and a method for metering additives in the washing in a dishwasher.
  • additives are needed, which are, for example, cleaning, washing, care, descaling and rinse aid and supplemental additives such as active chlorine or bleach.
  • the aggregates are generally available as a solid in the form of free-flowing powders, compressed powders, gels or liquids.
  • the quantities of additives required in each case must be determined before the start of the cleaning cycle - apart from z.
  • rinse aid generally be added manually by the user, the proportions of each agent are fixed without regard to the actual needs. Only the rinse aid is stored in highly diluted form in storage containers for several applications and automatically added via a metering device, if no combination product with integrated rinse aid is used.
  • a household detergent dispenser is known.
  • a powdered or liquid detergent and in another chamber a rinse aid is stored.
  • the additives are automatically fed to the cleaning process.
  • From the DE 4018582 A1 is a device for proportion-proportional dosage of additives to liquid detergents in a commercial dishwasher known. From a metering pump liquid detergent is transported via a conveyor line in the wash tank. Shortly before the confluence of the conveyor line in the Wash tank is an injector nozzle in the manner of a jet pump with a suction line to at least one storage vessel for liquid additives, eg. As hydrogen peroxide (H 2 O 2 ), active chlorine or anti-foaming agent arranged. Since both components, namely detergent and additive, brought together just before entering the wash and then unfold directly in the wash tank their approaching effect in the flushing process, there is no time for a chemical reaction. The disadvantage here is that a dosage of the additive to a limited extent only in dependence on the addition amount of the detergent and thus not independently possible. Furthermore, only individual liquid additives can be added.
  • H 2 O 2 hydrogen peroxide
  • the applicant is a device for single, metered delivery of several pumpable drugs known.
  • the pumpable active substances are conveyed from one storage container into a common working container and for mixing the promoted active substances with a working medium, in which the reservoir and a Hämediumansaug réelle be connected via individually controllable valves to a collecting channel, the collecting output via an airtight closing pump with the working container is connectable.
  • the disadvantage of this device is that, due to the use of a common working container, residues of active substances can react with other active substances, so that unwanted chemical reactions can occur. An independent and pure dosage of active ingredients in a treatment room is thus not possible.
  • a number of metering devices corresponding to the number of active ingredients or active substance combinations used are housed within the machine housing of the washing machine, the feeds of which are directly connected to an inlet connection of an associated active substance container.
  • active ingredients of the rinsing solution can be added.
  • the disadvantage here is that the method, the working equipment and the device can be used only in a washing machine, because there is another basic technical concept that can not be used in dishwashers, especially because of the use of substantially only washing-active substances and builders, because the remaining substances are generally not needed in dishwashers, and the structural design of the device. Furthermore, the process is predominantly designed to allow adaptation to certain water hardnesses or bleach proportions. An alignment, in particular to certain soiling cases is not possible. Furthermore, the deliverable drugs are limited to detergent substances, builders, stabilized bleaches, bleach-accelerating catalysts, organic acids, and fabric softeners, so that the process can be used only to a limited extent for applications that require these agents.
  • the EP 0 048 519 are provided on the same principle outside and separate from this only external container with associated pumps for cleaning powder of conventional composition, rinse aid and disinfectant.
  • the disinfectant is added before the start of the cleaning cycle in the washing liquid with the detergent.
  • the EP 0392 196 A1 deals with a level monitoring device for a storage and dosing device for storing several pumpable washing or rinsing agents such as heavy duty detergent, mild detergent, bleach and for their automatic metered addition.
  • the EP 1 186 694 A2 relates to a recording apparatus for a washing machine that controls the addition of various types of cleaning agents due to washing information transmitted via a communication network.
  • the additives used in the prior art for dishwashers, especially detergents consist of a mixture of different substances or basic chemicals (components) with different, each very specific tasks.
  • the additives used to date whether supplied manually or automatically, represent "all-round products” or “combination products”, which are designed for a very wide range of applications.
  • the detergents used in the prior art as compact dishwashing detergents consist of the following basic chemicals or components as additives: nonionic surfactants (wetting agents), phosphates (builders), soda and silicates (alkali carriers), perborate and TAED (bleach), amylase and proteases (enzymes) as well as anti-foaming agents, softeners, fragrances, dyes, disintegrants and coatings / binders (auxiliaries that are not directly involved in the cleaning process).

  • disintegrants and coatings / binders auxiliaries that are not directly involved in the cleaning process.
  • a liquid rinse aid is also generally used, which due to the required dosing accuracy about 97 vol. % consists of water and only effective as rinse aid to 3 vol .-%, in order to achieve a higher dosing accuracy, because in an overdose harmful foaming of the dishwasher occurs.
  • the object of the present invention is therefore to provide a dishwashing machine and a method which allow dishwashers to add only the basic chemicals necessary for the respective requirement, in particular basic chemicals from all-round products, into the washing container.

  • This allows a considerable increase in comfort for the user because, unlike the prior art, he no longer has to procure the aggregate independently, but instead they are automatically sent to the household. Due to the low consumption of aggregates because of the optimized dosage and the separation into components and the use of concentrates this also very low costs, because shipments only in relatively large time intervals, for example, only every three to four months, are necessary.
