Definitions

  • the invention relates to a spout for sanitary fittings with the features specified in the preamble of claim 1.
  • the service life of the outlet mouthpieces is usually determined by particles carried in the water and the excretions from the water, in particular lime deposits, which close the through openings. As has been confirmed by tests, the particles carried in the water generally have only a minor influence on the service life. In contrast, the calcium deposits from the water, which settle as deposits in the sieve and thus close the sieve mesh, cause a significant reduction in the service life. In the case of a supply network with a water of 18 to 22 ° dH, with a commercial outlet mouthpiece with a normal frequency of use, the jet pattern of the water emerging from the mouthpiece was clearly impaired after less than a quarter of a year.
  • the invention has for its object to provide an outlet mouthpiece according to the preamble of claim 1, which is relatively insensitive to lime deposits from the water.
  • the downstream sieve has a clear mesh size of about 1.2 mm to 5 mm, preferably square meshes with a clear mesh size of about 1.5 mm x 1.5 mm, and the one or more arranged upstream Sieves have a clear mesh size of approximately 0.5 mm x 0.5 mm.
  • DE-B 3 000 799 already mentions a favorable effect of a drain-side sieve with a coarser mesh size, although only a doubling of the mesh size to the upstream fine sieves is proposed.
  • Commercial fine sieves have a mesh size of about 0.5 mm. The outstanding importance of the largest possible mesh size with regard to the calcification behavior is obviously not recognized.
  • the lime deposits in the water are essentially completely harmless to the functionality of the outlet mouthpiece. This is probably achieved by the fact that, in normal periods of use, only the water droplet hanging in the lower sieve dries in the air and the lime deposits are deposited harmlessly on the coarse meshes of the lower sieve.
  • the adhesion of the lime deposits to the coarse-mesh sieve should also be reduced, since in an experiment with a commercially available outlet mouthpiece with unchanged sieves and a parallel outlet nozzle with sieves according to the invention, it was found that hardly any limescale deposits were found in the sieve according to the invention if that conventional sieve was almost completely closed with limescale.
  • the individual sieves can advantageously be made from calcification-insensitive material such as plastic.
  • An embodiment of the invention is shown in the drawing, partly in longitudinal section, as an outlet mouthpiece with a ventilation device and is described in more detail below.
  • the outlet mouthpiece shown corresponds with its housing 1 and a ventilation device 2 to a commercially available water jet aerator.
  • the outlet mouthpiece is connected with its housing 1 with the aid of a thread 11 and a seal 12 to the outlet pipe of a water tap fitting.
  • the outflowing water first passes through a strainer 3 with which coarse particles are separated from the water. Thereafter, the inflowing water is broken down into jet nozzles 21 into individual jets which have a high speed, which creates a negative pressure so that air is supplied to the water jets through air intake channels 22 and mixes with them.
  • Sieves 5, 6 are arranged at a distance from one another downstream of the ventilation device 2.
  • the screens 5 have a square wire mesh, each of which has a mesh size of 0.5 mm.
  • the downstream sieve 6 also has a square wire mesh, the clear mesh size of which is 1.5 mm.
  • the water-air mixture generated in the ventilation device 2 is homogenized by the sieves 5 and leaves the outlet mouthpiece through the sieve 6.
  • the remaining water remains adhering between the sieves 5 to 6 and forms a drop below the sieve 6, which has the total cross section of the outlet mouthpiece covered.
  • the water drop hanging below the sieve 6 dries and deposits the lime deposits on the lower sieve 6, which substantially prevents 5 lime deposits from occurring on the narrower sieves.
