Definitions

  • the invention relates to a device for improving the quality of drinking and / or industrial water according to the preamble of claim 1.
  • oligodynamically acting metal such as silver
  • the oligodynamically acting metal can be assigned an element with a different electrodynamic potential, as described in DE 35 43 223 AI.
  • Drinking water treated with UV radiation is used in particular in piping systems in the Federal Republic of Germany. This water is actually dead immediately after the irradiation and is therefore an excellent breeding ground for bacteria etc. It is also known that drinking water is often in pipes or pipe sections over a longer period of time. A Plastic pipes or other sections consisting of plastics, in which drinking water is stored for a longer period, represent a particular risk of a resulting bacteriological load up to contamination. Outbreaks of so-called legionnaires' disease have repeatedly become known from bathing establishments in recent years, the germs of which could multiply explosively and unpredictably in temperate sections of the drinking or fresh water pipes. At or in these breeding grounds, arrangements of filters, particularly against legionella, have proven to be largely ineffective.
  • oligodynamics describes a disinfection effect by releasing, for example, silver ions, which is disclosed, among other things, in German published patent application DE 35 43 223 AI for a water storage container made of stainless steel and in German patent specification DE 44 36 927 CI for an oral irrigator Plastic is used to kill germs.
  • the invention has for its object to provide a device for improving the quality of drinking and / or industrial water, which is suitable for use in shower hoses and for subsequent introduction in water-carrying pipes.
  • the device according to the invention consists of a flexible silver wire, over the entire length of which another metallic material extends, which is also designed to be flexible.
  • the other metallic material is preferably designed as an elongated coil spring in which the silver wire lies. It is particularly advantageous to manufacture the coil spring from stainless steel and to design it as a compression spring. Training as a compression spring has the advantage that There is a small free space between the individual turns of the coil spring, through which water can come into contact with the inserted silver wire. This has a positive influence on the oligodynamic effect.
  • a preferred embodiment provides that an end piece with a retaining pin engaging in the helical spring is placed on each end of the helical spring.
  • the coil spring can enclose the retaining pin so tightly that the end piece is held in the coil spring in a self-locking manner. Additional gluing or soldering is not necessary.
  • a braid of silver wires can represent an embodiment according to the invention.
  • a device comprises a silver wire or a braid made of silver, a silver wire being arranged together with a wire-shaped body or braid of a material with a different normal potential in the same line or in essentially the same line section. Due to the joint arrangement of the relatively inexpensive precious metal silver together with another material, a line or line section is also standing water according to the electrochemical voltage series of the metals and non-metals build up a potential gradient that counteracts the formation and / or multiplication of bacteria and germs in a very strong way. On the one hand, a static electric field is built up in a line or in a line section due to the difference in the normal potentials, which significantly impedes bacterial growth and is not dependent on an external supply of electrical energy.
  • silver ions are secreted, which are harmless to humans in the normally soluble concentrations in water and yet have a very strong oligodynamic property.
  • silver alloys with copper and / or palladium etc. should also be included synonymously by the designation of the precious metal, since silver alloys are also suitable for the separation of silver ions in a known manner.
  • the material with a normal potential other than silver essentially consists of a stainless steel.
  • a stainless steel in particular changes the taste of drinking water only insignificantly even in a device according to the invention, since it is largely corrosion-resistant in water at pH values of 6.5 to 6.9 and usual operating temperatures between about 6 ° and about 70 ° C. Even in interaction with silver, there is no taste impairment, discoloration or the like in drinking water.
  • other materials can also be added to the stainless steel as a carrier or added in particular by adding, fixing inlays, stranding etc.
  • the silver wire is advantageously coated on the surface with silver, in particular in a galvanic process.
  • the silver wire is washed before and / or after processing or in some other way superficially cleaned. Both measures ensure in themselves that a device according to the invention releases silver as particles and silver ions only to an extent immediately after installation, which is permitted under food law in drinking water.
  • a silver-plated wire for example a silver-plated copper wire, can also be used as the silver wire in the context of the present invention. Due to the decidedly longer service life, a wire made of solid silver is preferred. The same applies to a braid which, despite a concentration of the presentation of embodiments and further developments of the invention, should always be included on wire-shaped bodies without their own mention.
  • the silver wire and / or the other material are preferably arranged in a spiral in the one line or the line section.
  • a sufficiently large active surface is also created on a very short path.
  • the active surface can be further increased by training in the form of a braid or similar shapes.
  • the antibacterial effect is increased very effectively or is sufficiently strong when viewed over small lengths.
  • part of a device according to the invention is always in contact with the water or residual water from the silver wire and / or the other material, even when a line or line section is partially emptied, so that there is always a sufficient disinfection effect.
  • the at least two components of a device according to the invention are at least partially in close contact.
  • a silver wire is twisted with the other material or arranged around the other material.
  • a device according to the invention in a further development as twisted arrangement itself in a spiral shape, so that they also through small openings in a Cable, a hose or a piece of pipe can be virtually screwed in, pushed or inserted.
  • an average diameter of a spiral device is chosen such that it is smaller than a free diameter of the line or the line section.
  • a major advantage of a device constructed in accordance with the invention in accordance with this embodiment then lies primarily in the fact that it is flexible in a wide range, at least in this preferred embodiment.
  • a device according to the invention can thus be supplemented in a simple and quick manner in a line or a line section without substantial intervention in its mechanical stability or even weakening damage.
  • a spacer is advantageously provided on the device.
  • the spacer serves to prevent contact of the combination of silver and the other material with the material of the line section. This is particularly important in the case when the line or the line section does not consist of an insulator and thus additional ionization processes and consequently also corrosion phenomena can occur in contact with a device according to the invention.
  • the spacer itself is therefore preferably made of a plastic.
  • two or more spacers can also be connected to one another. This connection is preferably made flexible, as will be described below with reference to an exemplary embodiment with reference to the drawing.
  • a device according to the invention thus has a small overall length and is particularly suitable as a retrofit part.
  • An inventive The device is also designed as a line piece, which can advantageously be flexible in the form of a hose.
  • This opens up a wide variety of possible uses for a device according to the invention, from a shower hose, use on or with a aerator to use in an air conditioning system.
  • the defined and slow processes in a device according to the invention require, if at all, only very long maintenance intervals.
  • the service life of a hose, a seal, a sieve etc. can easily be achieved, so that no separate maintenance intervals need to be monitored.
  • a device according to the invention can also be attached quickly and easily due to its flexibility.
  • External connections by current sources are advantageously no more necessary than, for example, the provision of buffers against electrolytic decomposition of water with the risk of oxyhydrogen formation.
