Definitions

  • the invention relates to an aerator with an interior space formed below a decomposition unit, the decomposition unit having at least one water passage into the interior space, and with at least one insert part arranged in the interior space.
  • Jet regulators are known and are used to provide a water jet of the desired shape and/or quality, for example aerated or laminar, and/or flow class, preferably at the water outlet of a sanitary fitting or in a closed line. It is known to insert inserts in the form of insert grids into the interior, for example to improve mixing or homogenization of the water jet.
  • the object of the invention is to create an aerator with improved performance characteristics.
  • claim 1 The features of claim 1 are provided according to the invention to solve the stated problem.
  • the insert rests against the splitter unit at least in an area around the at least one water passage. Flow noise can be reduced by positioning the insert directly on the splitter unit. This improves the usage properties.
  • the splitter unit can have a diffuser in which, for example, an axially entering jet is deflected in a lateral direction and divided into individual jets and these individual jets are swirled and deflected in the axial direction.
  • Di f fusors are particularly suitable as a separating unit for lower flow classes. These individual beams are preferably arranged on a uniform radius, resulting in a ring arrangement of individual beams.
  • axial can refer, for example, to a longitudinal axis and/or a main flow direction of the jet regulator.
  • the splitter unit can have a perforated plate, in which, for example, an axially entering jet is divided directly into a large number of axially exiting individual jets.
  • Perforated plates are particularly well suited as a splitter unit for higher flow classes.
  • the individual jets are preferably distributed uniformly over a cross section of the interior.
  • the insert part is supported on the outflow side by at least a supporting element.
  • the insert can easily be held in its position of use. It is even possible for the insert to be pressed against the splitter unit.
  • the insert can be supported, for example, by at least one insert grid as a support element.
  • a support element that is easy to assemble can thus be used.
  • a mesh size of the insert is smaller than a mesh size of, for example, the one already mentioned downstream inlay grid is . It has been found that a particularly large reduction in noise can be achieved with particularly close-meshed inserts.
  • the term "mesh size" can, for example, imply a lattice structure or a network structure of the insert part and the at least one support element, in particular the at least one insert lattice.
  • the insert part is supported on an outlet structure on the outflow side. A stable arrangement of the insert can thus be achieved.
  • the insert part is supported at its periphery on a housing part that preferably laterally delimits the interior. Additional support elements are therefore not necessary.
  • the insert part covers and/or contacts the splitter unit in the lateral direction at least in the area of the water passages.
  • the insert part has at least one layer of a fabric.
  • a flat design of the insert can thus be achieved. This has been found to be beneficial for noise reduction.
  • a fabric can be characterized, for example, as an essentially two-dimensional object that consists of one-dimensional elements, such as wires, fibers, Filaments or threads, produced in a joining process, for example by weaving, knitting, knitting, fulling or braiding.
  • one-dimensional elements such as wires, fibers, Filaments or threads
  • the fabrics can be made of wire, for example.
  • metal meshes or metal fabrics or generally metallic flat structures can be used. Comparatively high stability and strength can be achieved.
  • the fabric is a textile fabric.
  • a particularly flexible sheetlike structure can thus be used. It has been found that this is particularly beneficial for noise reduction.
  • textile fabrics are woven, braided, felt, knitted or crocheted fabrics.
  • the material of the textile fabric can consist, for example, of natural fibers and/or chemical fibers, of natural polymers and/or of synthetic polymers and/or of inorganic fibers.
  • the natural fibers can be, for example, natural mineral fibers such as asbestos fibers or rock wool, natural plant fibers such as cotton fibers, flax fibers or hemp fibers, or natural animal fibers such as wool, silk or fur hair.
  • Chemical fibers made from natural polymers can be, for example, regenerated fibers based on cellulose such as viscose, lyocell or rubber.
  • Chemical fibers made from synthetic polymers can be, for example, polyacrylic nitrite, polypropylene, polyester, polyamide, polyurethane or a mixture thereof.
  • Inorganic fibers can be ceramic fibers, glass fibers or metal fibers.
  • Advantageous materials or combinations of materials can thus be used for the textile fabric based on the degree of noise reduction desired or the production process.
  • the insert has at least one layer of fabric. Tests have shown particularly good noise reduction properties for fabrics, especially when all layers are made of one fabric.
  • At least one layer is formed from plastic fibers and/or metal fibers and/or wire.
  • Plastic fibers are particularly favorable in terms of low deposits and food compatibility.
  • Metal fibers or wire for example, are favorable for dimensional stability.
  • All layers are preferably made of plastic fibers, for example woven, knitted, warp-knitted, milled or braided.
  • the at least one layer is punched. This enables simple manufacture.
  • the insert part has at least two layers. Tests have shown that particularly good properties with regard to low noise development result from a multi-layer structure.
  • the at least two layers enclose an intermediate space.
  • the formation of gaps favors further noise reduction.
  • the at least two layers are congruent. This enables simple manufacture.
  • the insert part is reinforced at its edge.
  • a stable support of the insert at its periphery can be achieved, for example without inner support elements.
  • the dismantling unit has a perforated plate. It has been found that good reductions can be achieved precisely for individual jets that emerge from a perforated plate.
  • the thickness of the insert is less than the thickness of the perforated plate. Comparatively thin inserts can thus be used.
  • the at least one support element supports the insert at a point spaced apart from an edge region of the insert.
  • the surface contact with the dismantling unit can also be supported in an interior area.
  • a distance between a support point can be at least 1/10 or at least 1/4 of a diameter or a maximum extent of the insert.

  • an impairment of a flow is low.
  • the support element can be arranged in the middle, for example.
  • a symmetrical structure or a symmetrical support is thus easily achievable.
