Definitions

  • the invention relates to a device for reduction of limescale from water, which is a channel flowed through in a sanitary facility, with at least one arranged in or on the flow-through channel Permanent magnets.
  • Examples of devices that contain permanent magnets and serve the purposes described are in the DE 42 13 805 A1, FR 26 88 012 A1, DE 295 08 819 U, DE 44 36 435 A1 or DE 87 17 348 U described. In all of these cases, the questionable Installation in a piece of pipe or hose outside the sanitary fitting inserted. It is there at a relatively large distance from the point which would be the most necessary effect, namely from the outlet area the respective sanitary facility. Also are these known devices are relatively complicated designed and complex to assemble.
  • EP 0 502 890 B1 described facility.
  • the proposal made certain items of the aerator from magnetic material, so the deposit-reducing effect within to achieve the aerator.
  • this measure is exclusively for use within Aerators limited.
  • the object of the present invention is a device of the type mentioned in such a way that they are easy to assemble and therefore particularly inexpensive is that they have a second function at the same time is able to fulfill, for which so far with sanitary facilities a separate component was used.
  • the permanent magnet into a tube-like part elastomeric material is integrated, which in the flowable Channel can be arranged and designed so that he at least with the wall of the flow-through channel forms an air-filled chamber and thus as a damper serves for flow noise.
  • Lime scale reducing device with to combine a muffler as he basically is already known and in different embodiments is used in sanitary facilities.
  • Such Silencers are based on the principle that the elastic Wall of a hose-like part under the influence against the sound generated by the flowing water an air cushion swings. These vibrations, under whose influence periodically compresses the air cushion are an energy dissipation mechanism, which leads to the desired sound absorption.
  • the Permanent magnet (or the permanent magnets) in the tube-like part integrated, so no special Holding structures needed for him more. Also an additional space requirement for the permanent magnet or magnets practically does not arise. It can namely in generally the one that is taken up by a silencer anyway or at least space available for him within the sanitary facilities themselves (i.e. not only in the supply lines to these sanitary facilities) be used.
  • the permanent magnet does not take up any additional space at all then one and no assembly effort arises then when the permanent magnet is in the form of a powder is present in the material of the hose-like part is embedded.
  • the permanent magnet can also be a solid one Shaped body designed and inserted into a chamber be formed in or on the tubular part is.
  • An embodiment of the invention is particularly preferred, in which in the flowable interior of the tubular structure is arranged, which swirls the flowing water. That one such swirling the deposit-reducing effect of the permanent magnet is known in and of itself, for example from DE 42 13 805 A1.
  • the swirling structure can be an insert which is inserted into the interior of the hose-like part is. However, it is particularly inexpensive Embodiment of the invention in which the swirling Structure integrally molded onto the tubular part is.
  • a particularly important area of application of the invention is that the tube-like part for insertion trained in the outlet channel of a sanitary fitting is. At this point, the invention unfolds Establish their greatest possible in both their functions Effect. Also at this point is in every sanitary fitting a suitable place to accommodate the invention Facility available.
  • Another preferred location for the invention is the interior of a shower hose.
  • Figure 1 shows a conventional hand shower in partial section 1, which has a curved grip area 2 and one itself this subsequent bell-shaped housing 3 comprises. Located on the underside of the bell-shaped housing 3 the shower base 4 with those in the drawing recognizable shower openings.
  • the grip area 2 of the hand shower 1 is hollow and contains a channel 5 through which the water from a bell-shaped shower hose, not shown Housing 3 and thus flows to the shower base 4.
  • a device is inserted into this channel, which overall carries the reference number 6 and both the damping of flow noise as well as the reduction of Limescale is used.
  • This device 6 is as follows built up:
  • a hose-like part 7 made of elastomeric material comprises a plurality at an axial distance from one another of annular projections 8 which are in the assembled position with its outer surface on the inner surface of the Channel 5 are present.
  • a plurality of annular chambers 9 Since the Installation of the device 6 in the hand shower 1 in a "dry" Condition occurs, the chambers 9 are filled with air. They remain so even when the hand shower 1 is in operation which flows through the hose-like part 7 of water becomes.
  • the wall of the hose-like part comes into play 7 in particular in the area of the chambers 9 in vibrations. These vibrations take place against that in the chambers 9 trapped air volume, which in a known manner damping the flow noise.
  • the material of the tubular part 7 is in finely divided shape, e.g. B. in the form of a more or less coarse-grained powder, magnetic material stored.
  • This magnetic material is known in and of itself Way to "condition" the water flowing through that lime deposits are reduced. This will especially the risk of constipation or pollution the shower holes in shower base 4 are reduced.
  • the effect of the contained in the tubular part 7 magnetic particle is shaped by a helical Installation 10 in the water-flowed interior 11 of the hose-like Part 7 supports.
  • Figure 2 shows a second embodiment of a Device for reducing limescale and for Sound absorption, which is similar to that of Figure 1 is. Corresponding parts are therefore with the same reference numerals plus 100 marked. The facility 106 is pushed into the same hand shower 1 that also is shown in Figure 1.
  • Means 106 is largely the same shaped like the device 6 of Figure 1. That is, it also comprises a hose-like part 107, the outside of which is spaced axially apart located annular projections 108 are formed. Between the handle area 2 of the hand shower 1 and the tubular part 107 of the device 106 is formed in this way in turn chambers 109, which also during the Operation of the hand shower 1 remain filled with air and in the manner described above the damping of the Flow noise serve.
  • the magnets that help reduce lime scale lead not in the form of a powder or the like into the material of the hose-like part 107 integrated. Rather, some of the chambers are 109 filled with magnetic material. This is what it is about preferably a molded body 111, which in the Gaps between adjacent ring-like projections 108 of the hose-like part 107 is inserted.
  • the device 106 also has an additional structure in the water-flowed interior 111, which with is designated by reference numeral 110 and the swirl of the water flowing through it. In the embodiment this device is direct from FIG molded onto the tubular part 107.
