Description

[0001] The invention relates to a sanitary insert part, in particular for insertion into a sanitary fitting and / or a pipe and / or a ball joint.

[0002] Furthermore, the invention relates to a use of a sanitary insert part for insertion into a sanitary fitting and / or a pipe and / or a ball joint.

[0003] The object of the invention is to improve sanitary inserts and their use.

[0004] To achieve the stated object, the features of claim 1 are provided according to the invention. In particular, to achieve the object in a sanitary insert, it is proposed that at least one textile fabric forms at least part of a downstream outlet stage of the sanitary insert. This can, for example, reduce noise that occurs when a fluid, for example water, flows through the sanitary insert. The textile fabric can be arranged as the last part of the sanitary insert in the direction of flow. The sanitary insert can be a jet regulator and / or flow regulator for insertion into a sanitary fitting and / or a pipe. The outlet can be the point at which water leaves the sanitary insert.

[0005] Alternatively or additionally, the features of the independent claim directed to a sanitary insert are provided according to the invention to achieve the stated object. In particular, to achieve the stated object in a sanitary insert of the type described above, it is proposed that a textile fabric be arranged immediately after a reducing stage. This can, for example, reduce noise when flowing through the sanitary insert. The reducing stage can be arranged upstream of the textile fabric in the flow direction. "Arranged immediately after the reducing stage" can mean, for example, that no further functional elements are arranged after the reducing stage, but that a small space exists between the reducing stage and the textile fabric, or that there is direct contact with the reducing stage.The advantage here is that noise generated by turbulence at the reduction stage can be dampened by the subsequent textile fabric. In particular, it can be provided that the textile fabric contacts the reduction stage. This makes it possible, for example, to have the textile fabric adjoin the reduction stage, which has a positive effect on noise development.

[0006] Alternatively or additionally, the textile fabric can be provided with a separation stage. This can, for example, enable the textile fabric to divide or separate a water stream into several parts, thereby achieving noise reduction.

[0007] In an advantageous embodiment, it can be provided that the textile fabric is supported against a flow direction. The support can thus counteract a water force acting on the textile fabric in the flow direction. This can, for example, ensure that the textile fabric retains its shape and is not bulged or washed out of the sanitary insert. In particular, the support can take place in a flow-through area, i.e. the area through which water flows through the sanitary insert. In particular, the textile fabric can be supported by a support, for example by a grid element which has grid struts running transversely to one another, such that the support is permeable to water. In the center of the support, this can have a pin.The support can be attached to the housing via a force-locking connection, for example a snap-in connection, so that it can withstand the water pressure.

[0008] In an advantageous embodiment, the sanitary insert can be provided with a screen positioned upstream of the textile fabric in the direction of flow. This can, for example, achieve noise reduction. Alternatively or additionally, the sanitary insert can be provided with a mixing stage positioned downstream of the textile fabric in the direction of flow. This can, for example, achieve an aerated jet.

[0009] In an advantageous embodiment, it can be provided that the textile fabric is supported on the downstream side by a support. The support can thus counteract a water force acting on the textile fabric in the direction of flow. This can, for example, ensure that the textile fabric stays in shape and is not bulged or flushed out of the sanitary insert. Preferably, the support can be latched. This can, for example, ensure that the support can be easily installed and held securely in place. Preferably, the support can form a cutting step. This can, for example, ensure that the cutting step and the support can be designed as a single piece. Alternatively or additionally, it can be provided that the textile fabric is clamped between the reducing step and the support or a support.This can, for example, ensure that the textile fabric remains safely and permanently in its intended location.

[0010] In an advantageous embodiment, the textile fabric can be woven. This can, for example, make the textile fabric particularly stable due to its weaving. Alternatively or additionally, the textile fabric can be knitted. This can, for example, make the textile fabric a warp-knitted fabric and thus particularly elastic. Alternatively or additionally, the textile fabric can be knitted. This can, for example, make the knitted fabric particularly elastic.

[0011] In an advantageous embodiment, it can be provided that the textile fabric is a fabric round. This can, for example, make it easy to produce the textile fabric as a fabric round. Alternatively or additionally, it can be provided that the textile fabric is made of a plastic. This can, for example, make it easy to produce the textile fabric and / or hardly deposit limescale on it and / or that no potentially hazardous substances are released into drinking water, thus making it easier to comply with drinking water guidelines and / or that the textile fabric is easy to produce or weave. In particular, it can be provided that the textile fabric is made of polyethylene terephthalate (PET).This allows the textile fabric to be produced particularly cost-effectively and also results in the advantages described in the previous sentence.

[0012] In an advantageous embodiment, it can be provided that the sanitary insert part has a flow control for controlling a flow rate. This can, for example, control a water flow rate, for example dependent on or independently of a water pressure. In particular, it can be provided that the flow control is a volume regulator. This can, for example, make it possible for the volume regulator to allow a predefined flow rate to pass depending on or independently of the applied water pressure. In this way, for example, a constant flow rate can be ensured through the sanitary insert part. For this purpose, the volume regulator has an O-ring which deforms depending on the water pressure and thus regulates the flow rate. Alternatively or additionally, it can be provided that the sanitary insert part has a flow control as a reducing stage for controlling the flow rates.This can, for example, make it possible for the reducing stage to control the flow rate that flows through the sanitary insert.

[0013] In an advantageous embodiment, it can be provided that a housing of the sanitary insert part is structureless on an outer side. This can, for example, make it possible for the housing to bear sealingly against the wall of a pipe and / or an outlet fitting. In particular, it can be provided that the outer side is not grooved. For example, it can have no grooves. Alternatively or additionally, it can be provided that the outer side is smooth. Alternatively or additionally, it can be provided that the outer side is profileless. Alternatively or additionally, it can be provided that the outer side is threadless. The advantages of the aforementioned embodiments lie in the optimal adaptation of the sanitary insert part for use in a pipe or a sanitary fitting so that it can be used there in a sealing manner.

[0014] In an advantageous embodiment, it can be provided that the textile fabric is made from at least two layers of textile fabric, wherein the individual layers can be welded together. This can, for example, make the textile fabric particularly stable and able to withstand high water pressure over a long service life. The welding can provide additional stability. A water flow can also be advantageously manipulated so that a low noise level is achieved during the flow. In particular, it can be provided that the individual layers are ultrasonically welded together. This can, for example, make the textile fabric quick and inexpensive to produce. Ultrasonic welding has the advantage that no additional material needs to be added.Ultrasonic welding is particularly suitable for the material-to-material bonding of two layers lying on top of each other.

[0015] In an advantageous embodiment, the textile fabric can have a mesh size between 600 micrometers and 1000 micrometers. This can, for example, make it possible to manipulate the water flow through the textile fabric in such a way that a low noise level is achieved. In particular, a mesh size of 800 micrometers of the textile fabric can be provided to achieve the best effect on the noise level of the flow.

[0016] In an advantageous embodiment, it can be provided that the textile fabric is woven, with a warp thread and weft thread being crossed with each other. This can, for example, result in the textile fabric having a regular structure, which has a positive effect on the noise level of the water flow. In particular, the warp thread and weft thread can be woven at right angles to each other. This can, for example, result in a particularly effective reduction in noise level. Alternatively or additionally, it can be provided that the textile fabric has a plain weave. This can, for example, result in each warp thread being alternately positioned above and below a weft thread, and each weft thread being alternately positioned above and below a warp thread. This can have a positive effect on the noise level of the water flow through the sanitary insert.

[0017] In an advantageous embodiment, the sanitary insert can be provided with at least two housing parts. This can, for example, make the housing structurally simple to manufacture. In particular, the housing can be provided with a two-part design.

[0018] This can, for example, make it possible for both or at least two housing parts to be fastened together, thereby enclosing a space between them.

[0019] Alternatively or additionally, it can be provided that the textile fabric is fastened to the first housing part with the aid of the second housing part. This can, for example, achieve a structurally simple fastening of the textile fabric to the first housing part. In particular, the textile fabric can be clamped to the first housing part. This can, for example, make it particularly easy to fasten the textile fabric. Alternatively or additionally, it can be provided that the textile fabric is held along its outer circumference. This can, for example, make it possible for water to flow through a large part of the textile fabric.

[0020] In an advantageous embodiment, it can be provided that a snap connection connecting two housing parts, for example the snap connection already mentioned, can be locked by inserting the sanitary insert part into a pipe. This can, for example, ensure that one wall of the pipe presses against the snap connection so that the latter is closed. Alternatively or additionally, it can be provided that a locking tongue of a snap connection connecting two housing parts, for example the snap connection already mentioned, is formed on one housing part of the two housing parts. This can, for example, ensure that the locking tongue can connect with the other housing part and create a snap connection. In particular, it can be provided that this housing part (second housing part) projects laterally beyond the other housing part (first housing part) of the at least two housing parts.This can, for example, make it possible to achieve a particularly simple but secure connection between the two housing parts.

[0021] In an advantageous embodiment, the textile fabric can be arranged downstream of the flow control. This can, for example, make it possible for the water to flow through the flow control before flowing through the textile fabric. In particular, it can be provided that the textile fabric is arranged downstream of the flow regulator. This can, for example, make it possible for the flow regulator to be fluidically connected upstream of the textile fabric.

[0022] In an advantageous embodiment, the second housing part can be connected to the first housing part in a force-locking manner. This can, for example, ensure that both housing parts are securely connected and yet can be separated from each other once a force holding the two housing parts together has been overcome. In particular, the force-locking connection can be a snap connection, which is structurally simple to manufacture.

[0023] Alternatively or additionally, to achieve the stated object, the features of the independent claim directed to a sanitary insert part are provided according to the invention. In particular, to achieve the stated object, in a sanitary insert part of the type described above, it is proposed that a second housing part forms a sealing element. This can, for example, make it possible to dispense with a sealing ring made of, for example, rubber. In particular, it can be provided that a wall of the second housing part forms a sealing element. This can, for example, make it possible to achieve a seal in a structurally simple manner, since a sealing ring can be dispensed with.

[0024] Alternatively or additionally, to achieve the stated object, the features of the independent claim directed to a use of a sanitary insert part are provided according to the invention. In particular, to achieve the stated object, the invention proposes a use of a sanitary insert part for insertion into a sanitary fitting and / or a pipe and / or a ball joint, characterized in that at least one textile fabric is arranged in a downstream outlet of the sanitary insert part. As a result, it can be achieved, for example, that the use of such a sanitary insert part enables a reduced noise level that arises when flowing through the sanitary insert part, compared to known sanitary insert parts.

[0025] The invention will now be described in more detail using an exemplary embodiment, but is not limited to the exemplary embodiment. Further exemplary embodiments arise from combining the features of one or more claims with one another and / or with one or more features of the exemplary embodiment.

[0026] They show: Fig. 1a sanitary insert in lateral sectional view, Fig. 2the sanitary insert from Fig. 1 in perspective sectional view, Fig. 3 the sanitary insert part from Fig. 1-2 in perspective view and Fig. 4 a textile fabric in detail, Fig. 5 an embodiment of the sanitary insert part a lateral sectional view, Fig. 6 the embodiment of Fig. 5 in a perspective sectional view, Fig. 7 a further embodiment in a lateral sectional view, Fig. 8 the embodiment from Fig. 6in a perspective sectional view and Fig. 9 a sectional view of the sanitary insert part from Fig. 7-8 an outlet side.

[0027] The Fig. 1 to Fig. 3 show a sanitary insert 1, designated overall by 1, for insertion into a sanitary fitting, a pipe, and / or a ball joint. The downstream outlet 2 of the sanitary insert 1 is formed by a textile fabric 3. In the embodiment shown, the sanitary insert 1 is a flow regulator 4.

[0028] The textile fabric 3 is arranged directly after a reducing stage 5 and forms a separating stage 6. The reducing stage 5 reduces and regulates a water flow through the sanitary insert part 1. The separating stage 6 separates a water flow into several parts. The embodiments of the Figures 5 and 6show a sanitary insert part 1 in which the textile fabric 3 is arranged directly after the reduction stage 5, wherein the sanitary insert part 1 has a front screen 35. The textile fabric 3 contacts the reduction stage 5. In addition, a mixing stage is arranged downstream of the textile fabric 3 in the flow direction 22.

[0029] The Figures 7 and 8show an embodiment in which the textile fabric 3 is supported against the flow direction 22 by a support 41, in this case a grid element 36. Here, the textile fabric 3 is positioned downstream of the reduction stage 5 in the flow direction 22 and rests on the grid element 36. The grid element 36 is latched to the housing 11 and thus supports the textile fabric 3 against water pressure. The latch 40 is designed as a force-locking connection between the grid element 36 and the housing 10. The support 41 is provided in a flow area 42 of the sanitary insert part 1, so that the textile fabric 3 is supported flatly.

[0030] Figure 9shows a view of the grid element 36 of the sanitary insert 3 from an outlet side. Struts 38 of the grid element 36 can be seen, which support the textile fabric 3 and are simultaneously permeable to water. A pin 39 is formed in the center of the grid element 36, which extends in the direction of flow 22.

[0031] The textile fabric 3 is supported on the downstream side by a lockable support 41 forming the disassembly stage 6. The Figures 1-2 and 7-8 show embodiments in which the textile fabric 3 is clamped between the reducing stage 5 and the or a support 41.

[0032] The textile fabric 3 is made as a fabric round 7 and from the plastic polyethylene terephthalate 8 (PET).

[0033] The sanitary insert 1 has a flow control 9, which in the illustrated embodiment is a flow regulator 4. The flow regulator 4 controls the amount of water that can flow through the flow regulator 4. An O-ring 10 can adapt to the water pressure and deform to allow a constant amount of water to flow through the flow regulator 4, or the sanitary insert 1, depending on the water pressure.

[0034] A housing 11 of the sanitary insert 1 is structureless on its outer side 12. In other embodiments not shown, the outer side 12 of the housing 11 is non-grooved, smooth, profileless, or threadless.

[0035] The textile fabric 3 in Fig. 1 and Fig. 2 is formed from four layers 13 of textile fabric 3, with the individual layers 13 welded together to form two layers. This construction increases the stability of the textile fabric 3.

[0036] Textile fabric 3 has a mesh size of 800 micrometers, with a thread diameter of 280 micrometers. This results in an open area of fabric 3 of 55%.

[0037] The textile fabric 3 is woven, with a warp thread 16 and a weft thread 17 interlaced at right angles to each other. The textile fabric 3 has a plain weave 18.

[0038] Fig. 4 shows a close-up of the textile fabric 3. The warp threads 16 and weft threads 17 are interlaced at right angles, resulting in the plain weave 18. The threads have a diameter of 280 micrometers.

[0039] The housing 11 of the sanitary insert 1 consists of two housing parts 19, 20. The textile fabric 3 is fastened to the first housing part 19 by means of the second housing part 20. The fastening is effected by clamping, with the textile fabric 3 being held along an outer circumference 21 of the textile fabric 3.

[0040] The textile fabric 3 is arranged downstream of the flow control 9, i.e., the flow regulator 4. In the embodiment shown, the flow regulator 4 represents the flow control 9. The flow direction through the sanitary insert 3, or through the flow regulator 4, is designated by 22.

[0041] The second housing part 20 is connected to the first housing part 19 in a force-locking manner by a snap connection 23.

[0042] A wall 24 of the second housing part 20 forms a sealing element 25. Thus, the sanitary insert part 1 can seal against a pipe or a sanitary fitting without an additional sealing element.

[0043] A sanitary insert 1, wherein a textile fabric 3 is arranged in a downstream outlet 2 of the sanitary insert 1, can be used for insertion into a sanitary fitting and / or a pipe. This advantageously results in low noise levels.

[0044] Fig. 1 and Fig. 2 show that the flow regulator 4 is held in a force-locking manner under an inwardly directed nose 26 of the first housing part 19. A water flow is guided through openings 27 of the flow regulator 4, laterally past a central segment 28 of the flow regulator and past the O-ring 10, after which the water flow is directed to the splitter stage 6.

[0045] An opening diameter 29 on the downstream side of the reducing stage 5 is smaller than an opening diameter 30 of the outlet 2 on its downstream side. A diameter 31 of the textile fabric 3 is larger than the opening diameter 29 on the downstream side of the reducing stage 5 and larger than the opening diameter 30 on the downstream side of the outlet 2. Thus, the textile fabric 3 cannot be flushed out of the sanitary insert 1 by water pressure.

[0046] The housing parts 19, 20 clamp the textile fabric 3 between them, so that a play 32 between the joined housing parts 19, 20 is bridged.

[0047] A sanitary insert part 1 is proposed, in particular for insertion into a sanitary fitting and / or a pipe, characterized in that at least one textile fabric 3 forms a downstream outlet 2 of the sanitary insert part 1. / List of reference symbols List of reference symbols
