Description

[0001] Aerator, outlet arrangement and method for assembling or disassembling a aerator

[0002] The invention relates to a jet regulator comprising a splitter unit with an external attachment point for attachment to a water stream, wherein a housing part has an outlet structure and is attached to a fastening point on the splitter unit. Such a jet regulator finds widespread practical application.

[0003] The invention further relates to a method for assembling and disassembling a jet regulator. Such a method is known.

[0004] The invention further relates to an outlet arrangement with a jet regulator and a mounting sleeve. Such an outlet arrangement is known.

[0005] The invention is based on the object of extending the service life of a jet regulator. The invention is also based on the object of providing a jet regulator in which limescale buildup can be easily removed by hand. The invention is also based on the object of reducing material costs and manufacturing complexity. This object is achieved by the features of the independent claims. Advantageous embodiments are described in the subclaims.

[0006] It should be noted that the features listed individually in the dependent claims can be combined with one another in any technologically expedient manner and define further embodiments of the invention. Furthermore, the features listed in the claims are further specified and explained in the description, with further preferred embodiments of the invention being presented.

[0007] To achieve this object, the invention proposes the features of claim 1. In particular, in a jet regulator of the type described above, the invention proposes that the housing part be made at least partially of an elastic material. Limescale buildup on the housing part can thus be easily rubbed off or removed by hand.

[0008] The engagement point can preferably be designed as a closed, circumferential rib. Alternatively, the engagement point can also be formed as part of a thread.

[0009] Advantageous embodiments of the invention are described below, which can optionally be combined with the features of claim 1 alone or in combination with the features of other embodiments.

[0010] In an advantageous embodiment, the attachment point can be provided downstream of the point of attack. Thus, improved mechanical stability can be achieved.

[0011] The disperser unit can be understood as a generic term and can, for example, comprise a diffuser unit and a disperser plate as variants. The diffuser unit can have a diffuser and a diffuser ring. For example, a disperser unit can be characterized as a functional unit which effects a decoupling of flow behavior within the jet regulator from flow behavior upstream of the jet regulator. In an advantageous embodiment, it can be provided that the housing part is elastic in one region of the wall. It is advantageous if the wall can be elastically deformable in this region. The wall can also be cylindrical. Limescale can therefore be removed relatively easily manually, in particular locally.

[0012] In an advantageous embodiment, the elastic material can be rubber, silicone, or a thermoplastic elastomer. This provides a cost-effective material that can reduce the overall material costs of the jet regulator.

[0013] In an advantageous embodiment, the engagement point can provide a material-locking and / or force-locking and / or form-locking connection. Thus, a connection with a simple design can be provided.

[0014] In an advantageous embodiment, the outlet structure can have webs and / or rings on the downstream side. The webs are preferably parallel, for example to form a rectangular grid, or branched in a network-like manner, for example to form a hexagonal grid. The webs are pronounced in the axial direction, with their dimension being larger in the axial direction than in the radial direction. This can provide stabilization of the outlet structure so that deformation of the outlet structure does not negatively influence the spray pattern.

[0015] Alternatively or additionally, the outlet structure can also have rings on the downstream side. Thus, outlet structures can be provided, for example, with several concentric rings, particularly connected with radially extending webs.

[0016] The rings or webs can be of different thicknesses in order to achieve local reinforcement of the bending line as required.

[0017] For this purpose, the bars or rings can be of different heights or different lengths.

[0018] In an advantageous embodiment, the webs and / or rings can have a cross-section that tapers in the direction of flow. This is beneficial for the recombination of the individual jets emerging from the outlet structure. Thus, a uniform and dynamic jet pattern can be achieved.

[0019] In an advantageous embodiment, the outlet structure can be reinforced with ribs on the upstream side. The ribs can be designed as transverse webs, whereby the transverse webs can be less high than the longitudinal webs. This can stabilize the outlet structure so that the jet pattern is not negatively affected under water pressure. The ribs can be made, for example, from the elastic material.

[0020] In an advantageous embodiment, it can be provided that the housing part consists of the elastic material at least in a wall region upstream of the outlet structure. Thus, an axial length of the housing part can be easily reduced by deformation. It is preferably provided that the wall region is made of the elastic material all the way around and / or in its entire axial extent. In this case, the terms "axial", "radial" and / or "circumferential direction" and / or "longitudinal" and / or "transverse" can refer, for example, to an insertion direction and / or a longitudinal axis of the jet regulator.

[0021] In an advantageous embodiment, the outlet structure can be made of an elastic material, preferably rubber, silicone, or a thermoplastic elastomer. Alternatively or additionally, the outlet structure can be formed integrally with the housing part. Thus, limescale buildup can be removed by simple manual rubbing.

[0022] In an advantageous embodiment, the housing part can be provided with a thickened portion which provides a radial seal acting outwards, for example towards an external mounting sleeve or a fitting, and / or inwards towards the splitter unit, in particular a splitter plate. Thus, a seal can be provided in a simple manner and / or a thread can be sealed on both sides. The thickened portion is preferably pronounced at the upper end of the housing part. An additional sealing ring is therefore unnecessary.

[0023] In an advantageous embodiment, the outlet structure can have a concave shape on the inflow side. This provides a stable shape that reduces deformation under the prevailing water pressure.

[0024] Preferably, the jet regulator has an outlet structure that is essentially adapted to the load.

[0025] In an advantageous embodiment, the outlet structure can have a convex shape on the upstream side. This provides a stable shape that reduces deformation under the prevailing water pressure.

[0026] In an advantageous embodiment, the splitter unit can be made of a stiffer material than the outlet structure. This provides greater stability for the jet regulator.

[0027] A splitter unit typically includes a diffuser and a diffuser ring or splitter plate.

[0028] In an advantageous embodiment, it can be provided that the outlet structure is / are manually deformable at least inwardly and / or the connected cylindrical region of the sleeve. The outlet structure can be more easily deformed inwardly than outwardly. This can be the case, for example, if the user attempts to contact tool engagement surfaces with a tool. This provides easier access to the tool engagement surfaces and enables the use of a variety of tools. A conceivable tool could be a coin, for example.

[0029] In an advantageous embodiment, the housing part can be provided with ventilation openings. This allows air to be easily drawn in and mixed with the water jet, resulting in a visually appealing spray pattern.

[0030] In an advantageous embodiment, it can be provided that the disassembly unit preferably extends from the inside through the ventilation openings. The disassembly unit can also extend from the outside through the ventilation openings. This provides a stable basic shape and prevents the housing part from slipping downward under water pressure. In an advantageous embodiment, it can be provided that the disassembly unit has a fastening point. This allows a simple connection between the disassembly unit and the housing part to be achieved.

[0031] The fastening point(s) can produce a snap connection, wherein the snap connection bevel angles can be selected, for example, such that either an angle of less than 90° or equal to 90° is included or at least a self-locking hold is ensured.

[0032] Alternatively or additionally, the fastening point(s) may be circumferentially limited. The presence of ventilation openings is not mandatory; however, such ventilation openings may be used to accommodate circumferentially limited fastening points.

[0033] In an advantageous embodiment, it can be provided that a lateral projection of a contact surface for a mouthpiece or mounting sleeve beyond the attachment point is less than or equal to a thickening of the housing part at the attachment point. This can prevent the housing part from slipping downwards and / or changing its position under prevailing water pressure, since it cannot fit through an annular gap that forms between the attachment point and the mounting sleeve due to the projection.

[0034] In an advantageous embodiment, it can be provided that the splitter unit comprises a diffuser and a diffuser ring. This makes it possible to provide a visually advantageous jet pattern. In an advantageous embodiment, it can be provided that the housing part engages in a groove of the diffuser ring on the upstream side. This makes it possible to stabilize the position of the housing part and prevent the housing part from slipping downwards under the water pressure. In an advantageous embodiment, it can be provided that an insert part is arranged between the splitter unit and the outlet structure. The insert part is preferably designed as one insert grid or several insert grids. The insert part can also be designed as one molded part or several molded parts. This makes it possible to increase the mechanical stability of the jet regulator and improve the jet pattern.

[0035] Preferably, the insert part is inserted into the outlet structure.

[0036] The insert preferably has upwardly projecting pillars and / or spikes, which ensure mixing of the water. These pillars and / or spikes can, for example, be connected to each other only at their bases. This allows for deformability in one direction, in which the free ends of the pillars and / or spikes can move away from each other, while the pillars and / or spikes rest against each other in the opposite direction and prevent deformation.

[0037] For example, these upwardly projecting pillars or spikes can be formed on an otherwise elastic outlet structure and stabilize it downwards by supporting each other.

[0038] In an advantageous embodiment, the insert part can be rigidly or elastically deformable. With a rigid design, the outlet structure can thus be stabilized or stiffened. With an elastic design, the elastic deformations cannot be hindered, which is advantageous.

[0039] To achieve the stated object, the features of the independent claim directed to a method for assembling and disassembling a jet regulator are provided according to the invention. In particular, to achieve the stated object, the invention proposes in a method of the type described at the outset that a tool is inserted into grooves or tool engagement surfaces so that an outlet structure of the jet regulator is elastically deformed. Thus, a large number of different tools can be used, since the outlet structure and / or overlying geometric parts made of rubber are elastically deformable. For example, it may also be possible to use a coin as a tool.

[0040] An advantage of the invention is that the outlet structure can protrude axially beyond a tool engagement surface without impairing the functionality of the tool engagement surface. This protrusion has the advantage of simplified cleaning.

[0041] To achieve the stated object, the features of the independent claim directed to an outlet arrangement are provided according to the invention alternatively or additionally. In particular, to achieve the stated object, the invention proposes that in an outlet arrangement with a jet regulator according to one of the aforementioned features and a mounting sleeve for fastening the jet regulator, a tool engagement surface is provided on the mounting sleeve on the downstream side, with which the mounting sleeve can be assembled and disassembled by a rotational movement and / or linear movement. Preferably, a housing part projects beyond the tool engagement surface. In this way, a robust structure can be provided.

[0042] According to the invention, it can be provided that the outlet arrangement comprises a jet regulator and a mounting sleeve for fastening the jet regulator, wherein on the downstream side there is a tool engagement surface on the mounting sleeve, with which the mounting sleeve can be assembled and disassembled, and wherein a housing part of the jet regulator is elastically deformable until the tool engagement surface is accessible for a tool. . Thus, numerous tools can be used and special production of the tools is no longer necessary. Special tools are no longer required due to the flexible housing part.

[0043] In an advantageous embodiment, the jet regulator can be arranged on a support shoulder of the mounting sleeve. This allows for optimal fastening and accessibility of the outlet structure, thus making it easy to clean during everyday use.

[0044] In one embodiment of the invention, it can be provided that a tool parting line is arranged on an inflow side of the outlet structure. Thus, an outlet structure can be easily manufactured using injection molding technology, the shaped elements of which, in particular webs or ribs, have a cross-section that decreases in the flow direction. The tool parting line can be characterized, for example, as a structure running around the workpiece and resulting from a parting line of an injection molding tool.

[0045] The invention will now be explained using a few

[0046] The invention is described in more detail in the exemplary embodiments, but is not limited to these few exemplary embodiments. Further variants of the invention and exemplary embodiments arise from combining the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiments and / or the previously described variants of inventive devices and predecessors.

[0070] In the following description of various embodiments of the invention, elements which correspond in their function are given the same reference numbers even if they have a different design or shape.

[0071] For clarity, not all reference symbols are shown in the figures, although the elements may very well be present in the figures. However, identical reference symbols denote functionally and / or structurally identical components and functional units.

[0072] Fig. 1 shows an outlet arrangement 1 in a sectional view. The outlet arrangement 1 comprises a jet regulator 2 and a mounting sleeve 3. The jet regulator 2 has a diffuser 4 and a diffuser ring 5. The jet regulator 2 furthermore has a housing part 6 which is made entirely of an elastic material and thus also in its wall region 24. The elastic material is preferably a rubber or a silicone or a thermoplastic elastomer. The housing part 6 comprises an outlet structure 7. The wall region 24 extends over the entire circumference of the jet regulator 2 and also over the entire (axial) height of the housing part 6 upstream or above the outlet structure 7.

[0073] The mounting sleeve 3 comprises a sealing ring 23 which is arranged radially. The elastic housing part 6 has a sealing function since it lies tightly against the diffuser ring 5 and is held in position by the mounting sleeve 3. The elastic housing part 6 can be elastically prestressed relative to the diffuser ring 5. The elastic housing part 6 lies tightly against the mounting sleeve 3, with the diffuser ring 5 forming a counter sealing surface. The elastic housing part 6 is held in position by the splitter unit 8 by means of the fastening points 10 on the one hand and the mounting sleeve 3 on the other. The sealing function acts simultaneously inwards and outwards.

[0074] Fig. 2 shows a jet regulator 2 in a sectional view from the front. The jet regulator 2 has a housing part 6 with an outlet structure 7 and a disperser unit 8. The disperser unit 8 comprises a diffuser 4 and a diffuser ring 5. The disperser unit 8 is made of a stiffer material than the outlet structure 7. The outlet structure 7 can be made of an elastic material, for example a rubber or a silicone or a thermoplastic elastomer. The housing part 6 has ventilation openings 9. The disperser unit 8 preferably engages from the inside through the ventilation openings 9. The mounting sleeve 3 is not shown in Fig. 2, but is present. The disperser unit 8 has a fastening point 10. A lateral projection of a contact surface 25 for a mouthpiece or a mounting sleeve 3 over the fastening point 10 is smaller than a material thickness of the housing part 6.The outlet structure 7 has webs 11 in the radial direction. The webs 11 are intended to provide the outlet structure 7 with a certain degree of stability, so that deformation of the outlet structure 7 due to water pressure is reduced. As an alternative to the webs 11, the outlet structure 7 can have rings 31. The webs 11 are preferably parallel or branched in a network.

[0075] Fig. 3 shows a perspective view of a splitter housing 12 and a housing part 6. The splitter housing 12 has fastening points 10, which can preferably be engaged from the inside through the ventilation openings 9 of the housing part 6. Fig. 4 shows the jet regulator from the front, with the splitter housing 12 and the housing part 6 assembled.

[0076] Fig. 5 shows a sectional view of an outlet arrangement 1 in a fitting 13. The outlet arrangement 1 comprises a jet regulator 2 and a mounting sleeve 3. The mounting sleeve 3 has a sealing ring 23 which is arranged radially on the mounting sleeve 3 and contacts and seals the fitting 13. The diameter of the sealing ring 23 is larger than the diameter of the thread 14 of the mounting sleeve 3. The mounting sleeve 3 can also be designed as a mouthpiece. The housing part 6 has ribs 15 which stiffen the outlet structure 7. The outlet structure 7 is also made of an elastic material, for example a rubber or a silicone or a thermoplastic elastomer, and can be formed integrally with the housing part 6. The jet regulator 2 furthermore has a flow regulator 16 which generates / defines a specific flow-pressure curve.The diffuser ring 5 has an external engagement point 17, which rests on a support shoulder 38 of the mounting sleeve 3. The housing part 6 engages in a groove 18 of the diffuser ring 5 on the upstream side. The housing part 6 can also serve as a radial seal to a nozzle or to the mounting sleeve 3; this eliminates the need for a separate seal or close tolerances and high surface requirements for a seal between hard materials.

[0077] Fig. 6 shows the outlet arrangement 1 from Fig. 5 in a perspective view from below. On the downstream side, tool engagement surfaces 19 are visible, onto which tools can engage. Since the outlet structure 7 is made of an elastic material, it can be deformed when a tool engages the tool engagement surfaces 19. A variety of different tools are also conceivable, for example, a coin. This eliminates the need for the design and provision of special tools, which represents a logistical and financial burden.

[0078] Fig. 7 shows a sectional view of an outlet assembly 1 in a fitting 13. The outlet structure 7 has ribs 15 that stabilize the outlet structure. The ribs 15 engage with the webs 11 and strengthen them. The webs 11 are preferably parallel or branched in a network. The idea here is to stabilize the entire outlet structure so that it deforms little or not at all under water pressure and produces an attractive spray pattern.

[0079] Fig. 8 shows the outlet arrangement 1 from Fig. 7 in a perspective view. In contrast to Fig. 6, there are no tool engagement surfaces 19, but a

[0080] Gripping surface 20. The gripping surface 20 can be rotated to screw the internal mounting sleeve 3 in or out.

[0081] Fig. 9 shows a jet regulator in a sectional view from the side. The outlet structure 7 has a convex shape. This convex shape ensures that the deformation of the housing part 6 takes place primarily at the wall, while still generating an attractive jet pattern. Fig. 10 shows an exploded view of Fig. 9 with a diffuser ring 5 of a disperser unit 8 and a housing part 6 in a perspective view from above. The housing part 6 has ventilation openings 9, which are

[0082] During operation, they can draw in air, which combines with the water jet to create a specific jet pattern. The splitter housing 12 has a circumferential attachment point 10, which can be designed as a snap connection. The splitter housing 12 also has an engagement point 17, which is designed as a circumferential rib.

[0083] Fig. 11 shows an outlet arrangement 1 in a sectional view from the side and in a fitting 13. Ribs 15 reinforce the outlet structure 7. A sealing ring 23 is arranged on the diffuser ring 5 and seals the splitter unit 8 against the fitting 13. In the embodiments shown so far, the sealing ring 23 was formed on the mounting sleeve 3 and sealed the mounting sleeve 3 against the fitting 13. The jet regulator 2 has an attachment sieve 21 and a flow regulator 16. The diffuser 4 is arranged within the diffuser ring 5. The housing part 6 engages in a groove 18 of the diffuser ring 5. The thread 14 of the mounting sleeve 3 is arranged on the inflow side. Fig. 12 shows the outlet arrangement 1 from Fig. 11 in a perspective view from the side. A tool engagement surface 19 is visible. The outlet structure 7 of the housing part 6 is deformable, allowing a variety of tools to be used.The separate production of special tools is no longer necessary. These special tools represent an additional burden on manufacturing costs, and keeping them constantly available is an organizational and logistical challenge.

[0084] Fig. 13 to Fig. 15 show the outlet arrangement 1 in a perspective view and with a tool 22. The deformed outlet structure 7 can be seen in Fig. 13 to Fig. 15. The tool 22 is shown here as a plate. Other shapes of tools 22 are also conceivable, for example a round or coin shape. The wall region 24 (not shown here) upstream of the outlet structure 7 can consist of an elastic material and can also be deformable. Fig. 15 shows the deformed outlet structure 7 and the deformed wall or wall region 24 (not visible here due to the representation of the fitting 13 and the mounting sleeve 3).

[0085] Fig. 16 shows an outlet arrangement 1 in a sectional view from the side. The outlet arrangement comprises a housing part 6, an outlet structure 7, a front sieve 21, a splitter plate 27 and an insert part 26. The insert part 26 is located between the outlet structure 7 and the splitter plate 27 and is inserted into the outlet structure 7. The housing part 6, which consists of an elastic material, has ventilation openings 9, which ensure air mixing during operation of the jet regulator and thus ensure a regular and visually attractive jet pattern. The insert part 26 is inserted into the outlet structure 7, but can also be cast onto it, and increases the stability in one load direction, namely in the direction of flow. The insert part 26 has upwardly projecting pillars or spikes which ensure that the water is mixed.The insert part 26 can be segmented in order to allow mobility of the housing part 6 in at least one direction. The insert part 26 can either be rigid, for example to stabilize or stiffen the outlet structure 7, or it can itself be elastic so as not to hinder elastic deformation. The insert part 26 can also have a different shape than that shown here. The outlet arrangement 1 furthermore has a sealing ring 23 which seals the fitting 13, the mounting sleeve 3 and the splitter plate 27. The outlet arrangement 1 furthermore has one or more fastening points 10 which engage in the ventilation openings 9 and are designed to protrude from the splitter plate 27. The fastening points 10 enable the splitter plate 27 to be aligned at the correct angle to the housing part 6. The outlet structure 7 has webs 11 or rings which are arranged at the water outlet.The webs 11 are preferably branched parallel or in a network-like manner.

[0086] The insert part 26 can be of higher rigidity than a bottom of the housing part 6, on the one hand for compression transverse to the flow direction and on the other hand for deflection in the flow direction.

[0087] The insert part 26 can also be inserted with a range of motion so that the insert part 26 can be lifted off when the bottom of the housing part 6 is deformed.

[0088] Fig. 17 shows the outlet arrangement in a perspective view from the outside (fitting side). Figures 18 and 19 show the splitter plate 27 and the housing part 6 in a perspective view. The splitter plate 27 has splitter openings 28 and outwardly projecting fastening points 10. An insert part 26 is arranged within the housing part 6 and is inserted into the outlet structure 7. The fastening points 10 ensure that the splitter plate 27 is aligned at the correct angle within the housing part 6. The insert part 26 can in this case contact the splitter openings 28 directly in an assembled arrangement. This results in further jet fragmentation and thus better homogenization of the water jet.

[0089] Fig. 20 shows a further outlet arrangement 1 in a sectional side view. The outlet arrangement 1 of Fig. 20 has similar components to the outlet arrangement 1 of Fig. 16. One difference is that the outlet arrangement in Fig. 20 has at least one insert grid 34. The housing part 6 consists at least partially of an elastic material, preferably a rubber or a silicone or a thermoplastic elastomer. The jet regulator 1 is arranged on a support shoulder 38 of the mounting sleeve 3.

[0090] Fig. 21 shows an outlet assembly 1 in a perspective view from the outside of the fitting. A tool engagement surface 19 is provided, into which a tool 22 can engage to loosen or tighten the mounting sleeve 3. Since the housing part 6 is made of an elastic material, it is deformable, allowing a variety of different tools 22 to engage the tool engagement surface 19.

[0091] Figs. 22 and 23 show the housing part 6 and the disassembly plate 27 in a perspective view. The housing part 6 has an insert part 26 designed as an insert grid 34. The fastening points 10 can be designed as snap connections. An insert part 26 is formed in the housing part 6 and is arranged on the outlet structure 7.

[0092] Multiple insert parts 26 may also be present. The strength of the insert part 26 can provide further stabilization if the housing part 6 is too yielding or too flexible.

[0093] Figure 5 also shows that a tool parting line 32, which is created by at least two injection molding tool parts that touch each other during injection molding, is arranged at the level of the inflow side 33 of the outlet structure 7. The tool that forms the webs 11 of the outlet structure 7 is thus demolded in the direction of flow. The webs 11 are therefore designed with a cross-section or profile which has a decreasing dimension in the direction of flow. In a jet regulator 2, comprising a splitter unit 8 and an external attachment point 17 for fastening in a water stream, wherein a housing part 6 has an outlet structure 7 and is fastened to a fastening point 10 on the splitter unit 8, it is proposed that the housing part 6 is made at least partially of an elastic material.
