Definitions

  • the invention relates to a aerator for faucet mouthpieces, with a cylindrical housing, air slots arranged in the housing and sieves inserted into the housing below the air slots, the aerator being insertable into a cylindrical housing and attachable to the faucet mouthpiece.
  • aerators The purpose of aerators is to let water-air mixtures emerge from the mouthpieces of taps. For this purpose, air is drawn into the side of the aerator, which is then mixed with the water jet to make it more productive and to dampen flow noises.
  • Below the louvers are a number of spaced-apart screens that divide the water jet and, as a result, the split water jet is thoroughly mixed with the air behind each screen.
  • the sieves are flat and have a flared spacing at their edge, so that adjacent sieves come to lie on top of one another in the region of the flare concerned and the spacing of adjacent sieves is thereby predetermined.
  • the known aerators have proven themselves in practice. It is disadvantageous for them, however, that the production of the flanging of the spacing of the individual sieves of the aerator is cost-intensive and, in addition, the outer sieves move over time.
  • the object is achieved in that at least one lens-like sieve arrangement formed from two sieves is provided.
  • the two sieves forming the sieve arrangement can be placed directly on top of one another with their edges without the need to flare each individual sieve.
  • Each sieve has a curved surface, the two sieves are joined together to form the lens-like sieve arrangement in such a way that the curvatures of the sieves point away from one another.
  • the production of the individual sieves is very simple, it is only necessary to punch out the individual sieves and to provide the curvature in one form.
  • the screens can be made of metal or plastic, for example, they can have a mesh or a perforated field.
  • optimal water-air mixtures result when the sieve arrangement is formed by a coarse and a fine sieve, the coarse sieve being arranged on the outside and the fine sieve on the inside. Even with two coarse sieves, however, there is a sufficiently good jet formation. It is sufficient for the optimal formation of a water-air mixture completely off if a single lens-like sieve arrangement is provided.
  • a preferred arrangement of the coarse sieve on the outside of the aerator according to the invention results in a longer service life due to a delayed calcification of the coarse sieve, since after the water flow has been interrupted by the aerator, it firstly retains only small amounts of water and, on the other hand, it is retained Evaporation of the lime deposits that form the adhesion water, move the larger meshes much more slowly.
  • the sieves can be produced and formed in a particularly cost-effective manner if two sieves with the same curvature are connected in the region of their edges by means of a web and the lens-like sieve arrangement is formed by folding the sieves together.
  • the screens connected by means of the web can simultaneously be produced by a tool, by collapsing the screens in such a way that the edges of the screens come to lie on one another and the curvatures of the screens point away from one another, the screen arrangement is formed.
  • Perlators have usually inserted a circular, cap-shaped, perforated part above the air slots in the housing.
  • the perforated part has the effect that the water jet is separated before the air slots and there is already an increased mixing of water and air in the area of the air slots.
  • the perforated part can have at least one spacer on its side facing the sieve arrangement, the free end of which comes into contact with the upper sieve of the sieve arrangement. By forming the perforated part with the spacer, the spacer presses over the upper sieve of the sieve arrangement onto the lower, outer sieve of the sieve arrangement, thereby it is ensured that the screen arrangement is held in a defined manner in the housing.
  • a particularly good beam formation using the new sieve formation results in combination with a flow limitation or flow control device above the perforated component.
  • Such a flow control device advantageously consists of a disc which is arranged on spaced ribs on the perforated component and has limited flexibility, which is provided with certain recesses for a reduced flow cross section.
  • the spacer ribs are expediently formed as an integral part on the top of the perforated part and extend radially from the center to the outside.
  • the recess in the limited flexible disc can advantageously be designed as a central hole. The water entering the housing passes through the central hole into the space between the disk and the perforated part, is divided by the ribs, flows through the perforated part past the air slots to pass through the screen arrangement.
  • an outward arch is advantageous sieve, in particular a fine sieve.
  • the strainer is used to hold back coarse dirt in the water being pumped.
  • the sieve should be arranged in the housing so that it is easy to remove, clean and reinsert.
  • a aerator 1 which has a cylindrical housing 2 with louvers 3.
  • the air slots 3 are located in one plane of the housing 2, a plurality of air slots 3 are arranged distributed over the circumference of the housing 2.
  • the water flows through the housing 2 in the illustration according to FIG. 1 from top to bottom.
  • the housing has an inward circumferential projection 4.
  • a sieve arrangement 5 is held by this attachment 4, which is inserted through the housing 2 from above during assembly.
  • the sieve arrangement 5 consists of two sieves which are arranged in a lens-like manner, ie the upper sieve 6 has an upward curvature, the lower sieve 7 has a downward curvature.
  • the circumferential edges of the screens 6 and 7 are supported on one another in the area of the housing 2.
  • the upper sieve 6 has a fine mesh
  • the lower sieve 7 has a large mesh.
  • the sieves are made of a metal wire, the wire diameter of the coarse sieve should be about 0.5 mm with a clear mesh size of about 0.5 to 1.5 mm, but preferably 0.8 to 1.3 mm, the diameter of the wire of the fine Sieve about 0.15 to 0.20 mm with a mesh size of 0.1 to 0.2 mm.
  • the housing 2 has a larger inner diameter in the area of an upper extension 8 than in the region of the lower extension 4.
  • the housing 2 receives in the region of the extension 8 a circular, cap-shaped part 9 which has a plurality of holes 11 penetrating the bottom 10 .
  • the part 9 On its side facing the sieve arrangement 5, the part 9 has a spacer 12, the free end of which comes into contact with the upper sieve 6 of the sieve arrangement 5. This ensures that when the part 9 is inserted, the sieve arrangement 5 is held in a defined manner in the aerator 1.
  • the part 9 On its upper side, the part 9 has five ribs 13, which radiate from the center of the part 9 and on which a disc 14 with a central hole 15 is arranged.
  • the disc 14 lies not only on the ribs 13, but also on a further circumferential projection 16 of the part 9. Above the disc 14 there is a fine sieve 17 which is curved outwards.
