Description

[0001] Beam govern

[0002] The invention relates to a jet regulator with an interior space formed beneath a splitter unit, wherein the splitter unit has at least one water passage into the interior space, and with at least one insert part arranged in the interior space.

[0003] Aerators 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 pipe. It is known to insert inserts in the form of grids into the interior, for example, to improve mixing or homogenization of the water jet.

[0004] The invention is based on the object of creating a jet regulator with improved usage properties.

[0005] To achieve the stated object, the features of claim 1 are provided according to the invention. In particular, to achieve the stated object, in a jet regulator of the type described above, the invention proposes that the insert be in contact with the splitter unit at least in an area surrounding the at least one water passage. By positioning the insert directly on the splitter unit, flow noise can be reduced. This improves the performance characteristics.

[0006] In this case, it is advantageous if the insert part lies flat, at least in the area mentioned. In an alternative, the splitter unit can have a diffuser in which, for example, an axially entering jet is deflected in a lateral direction and split into individual jets, and these individual jets are swirled and deflected in the axial direction. Diffusers are particularly well suited as splitter units for lower flow classes. These individual jets are preferably arranged on a uniform radius, resulting in a ring arrangement of individual jets.

[0007] The term "axial" can, for example, refer to a longitudinal axis and / or a main flow direction of the jet regulator.

[0008] Alternatively or additionally, the splitter unit can have a perforated plate, in which, for example, an axially entering jet is directly divided into a plurality 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 evenly across a cross-section of the interior.

[0009] In an advantageous embodiment, the insert can be supported on the downstream side by at least one support element. This makes it easy to hold the insert in its position of use. It is even possible for the insert to be pressed against the disassembly unit.

[0010] The insert can be supported, for example, by at least one insert grid as a support element. This allows for the use of an easily mounted support element.

[0011] In an advantageous embodiment, the mesh size of the insert can be smaller than the mesh size of a downstream insert grid, for example, the one already mentioned. It has been found that particularly close-meshed inserts can achieve a particularly significant noise reduction.

[0012] The term "mesh size" can, for example, imply a grid structure or a net structure of the insert part and the at least one support element, in particular of the at least one insert grid.

[0013] In an advantageous embodiment, the insert can be supported on the downstream side by an outlet structure. This allows for a stable arrangement of the insert.

[0014] In an advantageous embodiment, the insert can be supported at its periphery on a housing part that preferably laterally delimits the interior space. Thus, additional support elements are dispensable.

[0015] In an advantageous embodiment, the insert can be provided to cover and / or contact the splitter unit laterally, at least in the area of ​​the water passages. Thus, all individual jets emerging from the splitter unit can be captured. This further reduces noise generation.

[0016] In an advantageous embodiment, the insert can have at least one layer of a flat structure. This allows for a flat design of the insert. This has proven beneficial for noise reduction.

[0017] A fabric can, for example, be characterized as an essentially two-dimensional object that is made from one-dimensional elements, such as wires, fibers, filaments or threads, in a joining process, such as weaving, knitting, warp knitting, fulling or braiding.

[0018] The sheet materials can be made of wire, for example. Thus, metal mesh or metal fabric, or generally metallic sheet materials, can be used. A comparatively high level of stability and strength can be achieved.

[0019] In an advantageous embodiment, the fabric can be a textile fabric. This allows the use of a particularly flexible fabric. This has been found to be particularly beneficial for noise reduction. Examples of textile fabrics are woven, braided, felted, knitted, or warp-knitted fabrics.

[0020] The material of the textile fabric can, for example, consist of natural fibers and / or chemical fibers, of natural polymers and / or synthetic polymers and / or inorganic fibers. The natural fibers can, for example, be mineral natural fibers such as asbestos fibers or rock wool, plant natural fibers such as cotton fibers, flax fibers or hemp fibers, or animal natural fibers such as wool, silk or fur. Chemical fibers made from natural polymers can, for example, be regenerated cellulose-based fibers such as viscose, lyocell or rubber. Chemical fibers made from synthetic polymers can be, for example, polyacrylnitrite, polypropylene, polyester, polyamide, polyurethane or a mixture thereof. Inorganic fibers can be ceramic fibers, glass fibers or metal fibers.Based on the desired degree of noise reduction or the production process, advantageous materials or material combinations can be used for the textile fabric. In an advantageous embodiment, the insert can have at least one layer made of a fabric. Tests have shown particularly good noise reduction properties for fabrics, especially when all layers are made of one fabric.

[0021] In an advantageous embodiment, at least one layer can be formed from plastic fibers and / or metal fibers and / or wire. Plastic fibers are particularly advantageous in terms of low deposit formation and food compatibility. Metal fibers or wire, for example, are advantageous for dimensional stability.

[0022] Preferably, all layers are made of synthetic fibers, for example woven, knitted, warp-knitted, milled or braided.

[0023] In an advantageous embodiment, at least one layer can be punched. This allows for simple production.

[0024] In an advantageous embodiment, the insert can have at least two layers. Tests have shown that multi-layer construction results in particularly good properties with regard to low noise generation.

[0025] In this case, it can be provided that the at least two layers are connected to one another at their edges, preferably in a material-to-material manner. This enables the use of a compact unit in which the layers can be fixed relative to one another.

[0026] Alternatively or additionally, the at least two layers may enclose a gap. The formation of gaps promotes further noise reduction.

[0027] In an advantageous embodiment, the at least two layers may be congruent. This allows for simple production.

[0028] In an advantageous embodiment, the insert can be reinforced at its edge. This allows stable support of the insert along its periphery, for example, even without internal support elements.

[0029] In an advantageous embodiment, the splitter unit can be provided with a perforated plate. It has been found that significant reductions can be achieved, especially for individual jets emerging from a perforated plate.

[0030] In an advantageous embodiment, the thickness of the insert can be less than the thickness of the perforated plate. Thus, comparatively thin inserts can be used.

[0031] In an advantageous embodiment, it can be provided that the at least one support element supports the insert at a location spaced from an edge region of the insert. Thus, the flat contact with the disassembly unit can also be supported in an interior region.

[0032] For example, a distance of a support point can be at least 1 / 10 or at least 1 / 4 of a diameter or a largest dimension of the insert.

[0033] Alternatively or additionally, the support element can support the insert, preferably at one or more points, in a point-like manner. Thus, any flow impairment can be kept to a minimum.

[0034] The support element can, for example, be positioned centrally. This makes a symmetrical structure or symmetrical support easily achievable.

[0035] Alternatively or additionally, the support element can be arranged eccentrically to the insert. This allows for mechanically stable arrangements to be provided.

[0036] Preferably, support is provided at a location that lies between two adjacent holes of a disassembly unit, for example the one already mentioned, preferably centrally therebetween.

[0037] In an advantageous embodiment, the splitter unit can have conically shaped holes. Preferably, the diameter of the holes decreases in the direction of flow. The geometries of the holes can be identical or non-identical. Thus, a jet regulator can be provided that has particularly good noise characteristics.

[0038] The invention will now be described in more detail with reference to exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments result from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

[0050] Fig. 1 to 4 show a jet regulator according to the invention, designated as a whole by 1, and parts thereof.

[0051] The jet regulator 1 has a housing 2 in which a splitter unit 3 is arranged.

[0052] Downstream of the splitter unit 3, an interior space 4 is formed in which the individual jets emerging from the splitter unit 3 can mix and homogenize in order to emerge in a desired jet quality through an outlet structure 5 acting as a rectifier.

[0053] The splitter unit 3 has water passages 6 which each form a single jet as a nozzle and discharge it into the interior 4 .

[0054] In the interior space 4, an insert part 7 is arranged directly downstream of the disintegrator unit 3, which insert part 7 lies flat against the disintegrator unit 3 in the area 8 of the water passages 6.

[0055] The disintegrator unit 3 has a perforated plate 9 with holes 11 evenly distributed along a lateral direction 10, each forming a water passage 6. The holes 11 of the perforated plate 9 or of the disintegrator unit 3 are conical in shape, with a diameter of the holes 11 increasing in the flow direction. A support element 12 is formed below or downstream of the insert part 7, which holds the insert part 7 in contact with the disintegrator unit 3.

[0056] The support element 12 is arranged centrally and is held in the position of use by struts 34 of a very coarse-meshed insert grid 13, which divides the interior space 4 into four quadrants.

[0057] The central arrangement of the support element 12 can mean that the support element 12 is in a region of the insert part 7, wherein the region is given by a circular area whose radius is less than or equal to 80 percent, preferably 60 percent, particularly preferably 50 percent, of the total radius of the insert part 7 (Fig.1, Fig.5, Fig.8).

[0058] The support element 12 can support the insert 7 in a point-like manner. The support element 12 supports the insert 7 at a location spaced from an edge region 35 of the insert 7 (Fig. 5; Fig. 8).

[0059] The insert part 7 is supported indirectly on the outlet structure 5 via the support element 12.

[0060] By comparing Fig. 3 and 4 it can be seen that a mesh width 14 of the insert part 7 is smaller than a mesh width 15 of the insert grid 13.

[0061] In the example, mesh size 14 is a fraction of mesh size 15.

[0062] Fig. 5 shows a further embodiment of a jet regulator 1 according to the invention. Components and functional units that are functionally and / or structurally similar or identical are designated by the same reference numerals and are not described separately again. The statements regarding Figs. 1 to 4 therefore apply accordingly to Fig. 5.

[0063] The embodiment according to Fig. 5 differs from the preceding embodiment at least in that the support element 12 is formed integrally on the outlet structure 5.

[0064] The support element 12 supports the insert part 7 at a location spaced from the edge region 35 of the insert part 7. The support element 12 can support the insert part 7 in a point-like manner.

[0065] The support element 12 can have a cylindrical or conical shape. Thus, different flow profiles can be generated in the interior space 4.

[0066] Fig. 6 shows a further exemplary embodiment of a jet regulator 1 according to the invention. Again, structurally and / or functionally similar or identical components and functional units to the preceding exemplary embodiment are designated by the same reference numerals and are not described separately. The statements regarding Figs. 1 to 5 therefore apply accordingly to Fig. 6.

[0067] The embodiment according to Fig. 6 differs from the preceding embodiments in that the insert part 7 rests on its circumference 16 on a shoulder 17 of a housing part 18.

[0068] The housing part 18 delimits the interior space 4 in the lateral direction 10 .

[0069] Fig. 7 shows a further exemplary embodiment of a jet regulator 1 according to the invention. Again, structurally and / or functionally similar or identical components and functional units to the preceding exemplary embodiments are designated by the same reference numerals and are not described separately again. The statements regarding Figs. 1 to 6 therefore apply accordingly to Fig. 7.

[0070] The embodiment according to Fig. 7 differs from the preceding embodiments in that several insert grids 13 are arranged in a stacked arrangement in the interior 4, which together support the insert part 7 and press it against the disassembly unit 3.

[0071] Fig. 8 shows a further exemplary embodiment of a jet regulator 1 according to the invention. Again, structurally and / or functionally similar or identical components and functional units to the preceding exemplary embodiments are designated by the same reference numerals and are not described separately. The statements regarding Figs. 1 to 7 therefore apply accordingly to Fig. 8.

[0072] The embodiment according to Fig. 8 differs from the preceding embodiments at least in that the insert part 7 is supported by an eccentrically mounted support element 12 which is placed in the outlet structure 5 and held by it.

[0073] The support element 12 supports the insert 7 at a location spaced from the edge region 35 of the insert. The support element 12 can support the insert 7 in a point-like manner.

[0074] The support element 12 can be in one piece or in several pieces, in particular in two pieces, with the outlet structure 5.

[0075] In Fig. 1 and 5 to 8 it can be seen that the insert

[0076] 7 according to Fig. 3 is formed from two superimposed layers 19. These layers 19 are each formed as a sheet-like structure 20.

[0077] Each sheet 20 is made of one-dimensional elements 21, for example wire 22 (see Fig. 3) or plastic fibers 23 (see Fig. 9), for example woven or braided.

[0078] Fig. 10 illustrates a possible production of a multi-layer insert 7 using the example of three layers 19.

[0079] Each layer 19 is made from a web 24, which is shown in the left half of Fig. 10.

[0080] The webs 24 can be configured differently or identically. The webs 24 can differ in terms of material selection and / or joining technique and / or mesh size.

[0081] The webs 24 are placed on top of each other - as shown in the right half of Fig. 10 - and cut out together along punching lines 25.

[0082] Fig. 11 shows a schematic diagram of an axial section through the finished insert 7.

[0083] It can be seen that a material connection 26 is formed on the edge 27 of the insert part 7, so that spaces 28 lying one above the other are formed in the interior space 2.

[0084] The material connection can be created, for example, by ultrasonic welding before, during, and / or after punching. Fig. 3 also shows that the edge 27 can be provided with a reinforcement 29, in particular to enable support of the insert 7 on the periphery 16.

[0085] In the sectional views according to Fig. 1 and Fig. 5 to 8 it can also be seen that a thickness 30 of the insert 7 is smaller than a thickness 31 of the perforated plate 9.

[0086] In the illustrated embodiments, the housing 2 is constructed in two parts and can be opened at a connection point 33 downstream of the disintegrator unit 3. Thus, the interior space 4 is accessible, for example, to insert the insert part 7 and / or the at least one insert grid 13 and / or the at least one support element 12 into the interior space 4.

[0087] In the jet regulator 1 according to the invention, it is thus proposed to arrange an insert part 7 directly behind a splitter unit 3 in an interior space 4 of the jet regulator 1, wherein the insert part 7 lies flat against an outflow side of the splitter unit 3.
