Description

[0001] Sanitary insert, corresponding use, method, series, fluidic arrangement and corresponding use

[0002] The invention relates to a sanitary insert with a separating stage and a mixing stage formed downstream of the separating stage, wherein the mixing stage has an arrangement of flow obstructions lying transverse to a main flow direction, wherein the flow obstructions project from a support.

[0003] The invention relates to a sanitary insert with a separating stage and a mixing stage formed downstream of the separating stage, wherein the mixing stage has an arrangement of flow obstructions lying transverse to a main flow direction.

[0004] The invention also relates to the use of an arrangement of flow obstructions projecting from a support for forming a mixing stage of a sanitary installation part.

[0005] Furthermore, the invention relates to a method for forming a sanitary insert, a method for introducing an arrangement of flow obstructions into a sanitary fitting, and a method for introducing a sanitary insert into a sanitary fitting.

[0006] Furthermore, the invention relates to series of sanitary insert parts with at least two variants of sanitary insert parts.

[0007] Furthermore, the invention relates to a fluidic arrangement with a connection part on which a hose connection and a receptacle for a sanitary insert, in particular a sanitary insert as described herein, and / or an aerator, are formed, wherein the receptacle and the hose connection are in fluidic communication. The invention also relates to the use of a connection part of a fluidic arrangement for supplying air from outside the connection part to a sanitary insert placed in a receptacle of the fluidic arrangement.

[0008] A sanitary fitting of the type described here is known, for example, as an aerator. The aforementioned use of an arrangement of flow obstructions, the aforementioned methods, and the product series are also known.

[0009] Typical sanitary inserts include, for example, a pre-filter, a reduction stage, a separation stage, a mixing stage, and / or a discharge stage as functional stages, through which fluid flows in that order. Sanitary inserts are also known in which one or more of these stages are missing.

[0010] The reducing stage can be designed, for example, to reduce a flow rate. For instance, the reducing stage can be configured as a throttle, reducing the flow rate by a factor dependent on a pressure difference within a given operating range. Alternatively, the reducing stage can be configured as a flow regulator, reducing the flow rate to a value that is practically or precisely independent of the pressure within a given operating range. Flow regulators often incorporate an elastic control element that is deformable by an operating pressure and changes the area of ​​a flow opening depending on the pressure.

[0011] One possible function that can be realized with a separation stage, particularly the one described here, is to fluidically decouple flow conditions upstream of the separation stage from flow conditions downstream. Another characteristic of the separation stage can be, for example, the separation of an incoming fluid into a multitude of individual jets. For this purpose, the separation stage comprises a separation unit, also referred to as a separation structure. The separation stage, and in particular the separation unit, can, for example, have an arrangement of holes from which individual jets emerge. The separation stage can, for instance, be designed as a separation plate with an arrangement of holes. Furthermore, the separation stage can have an arrangement of separation nozzles. Alternatively or additionally, the separation stage can be designed as a diffuser or in some other way.

[0012] A mixing stage can follow the dispersing stage, typically incorporating flow obstructions to ensure thorough mixing and turbulence of the individual jets generated by the dispersing stage. This mixing stage may also include an air intake, created by a negative pressure behind or at the dispersing stage, which can be used to generate an aerated jet.

[0013] In practice, it is known to insert flow obstructions in the form of grid inserts into the mixing stage, which can be made of different materials.

[0014] A final outlet stage, which can be designed as an outlet structure, for example, can perform rectifying functions, such as generating a unidirectional outflow. Another function of an outlet stage can be, for example, to form a fluidically permeable termination of the mixing stage.

[0015] The invention is based on the objective of simplifying the manufacture of a sanitary insert and / or increasing the possible applications of a sanitary insert. To solve this objective, the invention proposes the subject matter of the independent claims.

[0016] In particular, the invention proposes the features of claim 1 to solve the aforementioned problem. To solve the aforementioned problem in a sanitary insert of the type described above, the invention proposes that an outlet stage formed downstream of the mixing stage be firmly connected, in particular integrally, to the support of the mixing stage.

[0017] The main flow direction can be determined, in particular, by vectorially plotting the flow direction at each point of the sanitary fitting as a whole at a single point, whereby the main flow direction can be calculated as the average of all these flow directions. Often, the main flow direction is opposite to the direction in which the sanitary fitting can be inserted into a sanitary valve.

[0018] A rigid connection between the support and the exit step can be achieved, in particular, by a positive-locking, force-locking, and / or material-locking connection between these two components. Preferably, this rigid connection can be designed as a captive connection. Additionally or alternatively, this rigid connection can exhibit only minimal or no play between the support and the exit step. A particularly rigid connection between the support and the exit step can be achieved by forming these two components as a single piece.

[0019] Due to the firmly connected, especially one-piece, design of the support with the outlet step, the support with the flow obstructions and the outlet step can be easily integrated together in a single outlet section of a

[0020] Sanitary fittings are to be arranged.

[0021] In particular, the support with the flow obstructions and the outlet stage can be inserted into and arranged in the sanitary fitting through an outlet opening of a sanitary fitting, contrary to the main flow direction intended in the normal operation of the sanitary insertion device.

[0022] The flow obstructions can be designed in a particularly straight and / or rod-like form. In a direction transverse to the main flow direction, the flow obstructions, which are designed in a particularly straight and / or rod-like form, preferably do not extend beyond one end of the outlet step.

[0023] In practice, the outlet step may be designed to be round. Additionally or alternatively, it may be designed to allow the discharge step to emit a round jet. Again, additionally or alternatively, the outlet step may be designed as a round discharge structure. In its intended use, a round discharge step has a round, in particular circular, outer circumference and / or a round flow cross-section perpendicular to the main flow direction. For example, the outer circumference of the discharge structure may be round. A round jet may be emitted, for example, by having a round flow cross-section that limits the flow area for the jet.

[0024] If the outlet stage is fixed, particularly integrally, connected to the support and is round, or at least allows for the emission of a round jet, the round outlet stage can be easily implemented, thus making a round jet, which is popular in practice, quickly available and / or adaptable. Alternatively or additionally, the features of the dependent claim, which also relates to a sanitary component, can be provided to solve the aforementioned problem. In this case, for a sanitary component with a separating stage and a mixing stage formed downstream of the separating stage, wherein the mixing stage has an arrangement of flow obstructions lying transversely to a main flow direction, it is proposed according to the invention that the flow obstructions are arranged on the support in at least two levels.An advantage of this is that good mixing in the manner of a cascade can be achieved when a fluid, especially water, flows through the sanitary fitting as intended.

[0025] The sanitary insert can in particular be a sanitary insert of the type described at the beginning and / or a sanitary insert of the type described above.

[0026] In particular, at least two of the at least two levels can be aligned parallel to each other. This allows a fluid, especially water, to be influenced in a particularly homogeneous way, thus creating a controlled jet. Furthermore, this allows for a compact design of the sanitary fitting.

[0027] In one embodiment of the invention, it can be provided that the flow restrictors, in particular with the outlet stage and / or the separation stage, can be inserted into a housing part in the direction of flow and / or against the direction of flow. This facilitates the formation of a mixing stage in the sanitary inlet part by subsequently inserting the fully formed flow restrictors.

[0028] For example, it can be designed that the disassembly stage and / or the discharge stage and / or the support (and / or another part that can be used together with the flow obstructions) makes sealing contact with the housing part. This reduces or prevents unwanted leaks.

[0029] The housing part can, for example, be a downstream open basket or one closed with a discharge structure and / or be integrally connected to or carry a disassembly stage.

[0030] Housing part and disassembly stage, flow obstructions, support and discharge stage can generally be manufactured in pairs or in groups of more than two elements from a matching material.

[0031] Alternatively or additionally, the features of the dependent claim, which also relates to a sanitary insert, can be provided to solve the aforementioned problem. In this case, it is proposed according to the invention that, in a sanitary insert of the type described at the outset or in a sanitary insert of the type described above, two adjacent levels of the at least two levels overlap at least partially in the main flow direction. This allows for a particularly compact design of the sanitary insert.

[0032] The sanitary insert can in particular be a sanitary insert of the type described at the beginning and / or a sanitary insert of the type described above.

[0033] The flow obstructions of a second of the two adjacent levels can, in particular here, be arranged laterally offset from the flow obstructions of a first of the two adjacent levels. In particular, the flow obstructions of the second of the two adjacent levels can be arranged, at least with a section, in a free space between two adjacent flow obstructions of the first of the two adjacent levels. The levels can, in particular thus, be arranged partially nested within one another.

[0034] Furthermore, in practice, it may be provided that the flow obstructions in at least one level are aligned parallel to each other. In particular, the flow obstructions in at least one of the at least two levels may be aligned parallel to each other. The parallel alignment of the flow obstructions in the level or in at least one of the levels does not require that all flow obstructions in that level be arranged parallel to each other, even though this may be implemented in practice. It is also possible that the level or at least one of the levels has a plurality of areas with flow obstructions, whereby the flow obstructions contained in one of the areas may be arranged parallel to each other. If a plurality of levels is provided, the parallel arrangement described here may be implemented in each of these levels.The parallel alignment allows for particularly good mixing of a fluid flowing through the sanitary insert as intended and / or a compact design.

[0035] Alternatively or additionally, the features of the further dependent claim, which also relates to a sanitary insert, can be provided to solve the aforementioned problem. In this case, to solve the aforementioned problem in a sanitary insert with a separation stage and a mixing stage formed downstream of the separation stage, wherein the mixing stage has an arrangement of flow obstructions lying transversely to a main flow direction, it is proposed according to the invention that the flow obstructions are arranged in at least one level, wherein at least one of the at least one level has at least two areas, wherein the orientation of the flow obstructions in at least two of the at least two areas differs from one another.In other words, at least one of the floors described here may contain two or more areas with flow obstructions oriented differently across the areas, the different orientation of the flow obstructions being determined by a direction in which the flow obstructions project from the support.

[0036] The at least two areas of a floor can, for example, be adjacent to each other on that floor. In particular, the flow obstructions in each of these areas can be aligned parallel to each other.

[0037] As described, the flow obstructions can be arranged on at least two levels. In this case, the orientation of the flow obstructions described here can be implemented in at least one, or at least two, of the at least two levels.

[0038] By forming the areas on at least one level, especially in combination with the formation of at least one further level of flow obstructions, the flow obstructions can be arranged particularly well distributed within a flow cross-section of the mixing stage. Thus, the flow in the mixing stage can be mixed particularly well, especially without the flow being able to penetrate deep into the mixing stage unhindered.

[0039] If at least one level, and in particular at least one of the at least two levels described herein, has the described at least two areas, it may be provided in practice that the flow obstructions in a second area of ​​the at least two areas are oriented transversely to the flow obstructions in a first area of ​​the at least two areas. It is also possible that three or more areas are provided, with the flow obstructions in the second and third areas being oriented transversely to the flow obstructions in the first area. Due to the transverse orientation of the flow obstructions, they can be distributed particularly efficiently within the flow cross-section of the mixing stage.

[0040] In particular, the flow obstructions in the second area, and optionally the third area, can be aligned orthogonally to the flow obstructions in the first area. An orthogonal alignment achieves an excellent compromise between efficient distribution of the flow obstructions and excellent manufacturability of the support structure with the flow obstructions and, if applicable, with the outlet stage.

[0041] In practice, it may additionally or alternatively be provided that the orientation of the flow obstructions, in particular the orientation of the flow obstructions described here, includes an angle between two of the at least two described levels. In other words, the flow obstructions of these two levels may be rotated relative to each other with respect to a longitudinal axis, which may be oriented parallel to the main flow direction. In particular, the orientation of the flow obstructions of two adjacent levels may include an angle. Additionally or alternatively, the angle may be 90°, so that the flow obstructions in the two levels may be rotated orthogonally to each other. The angle described above may, in particular, be included between the flow obstructions of two levels with flow obstructions oriented parallel to each other.

[0042] In particular, if the sanitary installation unit has at least two floors and at least one of these floors has two areas, it may additionally or alternatively be provided that an orientation of the flow obstructions, in particular the orientation of the flow obstructions described here, forms an angle between two areas of the at least two floors. In other words, the flow obstructions of an area of ​​a first of the two floors may be rotated relative to a longitudinal axis relative to the flow obstructions of an area of ​​a second of the two floors.

[0043] In particular, the orientation of the flow obstructions of two adjacent areas can involve an angle. Additionally or alternatively, the angle can be 90°, so that the flow obstructions in the two areas can be rotated orthogonally to each other.

[0044] In practice, it may also be possible for the separating stage to be formed integrally with the support of the mixing stage. This makes it possible to easily arrange the separating stage, the support with the flow restrictions, and the outlet stage together in a single outlet piece of a sanitary fitting. Furthermore, this allows for a particularly suitable orientation of the flow restrictions relative to the separating stage to be predetermined during the manufacturing of the sanitary fitting, especially an orientation in which the flow restrictions are arranged parallel to the described outlet structures of the separating stage.

[0045] Alternatively, in practice, the support can be connected to the disassembly stage via a support connection. This support connection can be force-fit and / or form-fit. In particular, the support connection can be captive, for example, by latching or snapping. If required, the support can also be detachably connected to the disassembly stage.

[0046] If the carrier is connectable to the disassembly stage, it is possible to flexibly and easily combine different variants of disassembly stages with different variants of carriers, different variants of flow restrictors, and / or different variants of discharge stages. A further advantage is that the carrier with the flow restrictors can be manufactured separately from the disassembly stage. This can simplify tool design for injection molding. With a detachable carrier connection, the aforementioned combination can be modified subsequently, allowing for adaptation to changing requirements while minimizing waste. With a non-detachable carrier connection, the advantage is that it prevents the unwanted loosening or subsequent replacement of components of the combination.

[0047] In practice, if the discharge stage can be connected to the separation stage via the support, this connection may have a non-symmetrical and / or non-circular interface. In particular, the support connection may have this interface. Additionally or alternatively, this interface may define an orientation of the flow obstructions relative to the separation stage with respect to rotations about a longitudinal axis parallel to the main flow direction. This allows for easy alignment of the flow obstructions with a pattern or arrangement of holes in the separation stage, without requiring subsequent checks or increased assembly effort. It is thus easily achieved that the separation nozzles and flow obstructions automatically align themselves, or that the separation nozzles and flow obstructions are precisely aligned with each other.

[0048] In particular, the separating stage, designed, for example, as a separating plate or diffuser, can have a recess, and the support can have a projection that geometrically corresponds to the recess, in particular that is at least partially geometrically complementary. The recess can be formed, in particular, at the center of the separating stage. Additionally or alternatively, if the separating stage is intended to be arranged in a sanitary fitting, the recess can be accessible and / or passable in an orientation parallel to the main flow direction. This allows the projection of the support to be inserted into the recess particularly easily, especially if the separating stage is already arranged in a sanitary fitting, namely by moving the support with the projection into the recess against the main flow direction.The projection corresponding to the recess can, for example, be formed on the intended inflow side of the carrier and / or the mixing stage. Additionally or alternatively, the recess can be formed in the center of the mixing stage. This allows the projection of the carrier to be easily inserted into the recess.

[0049] A cross-section of the projection and a cross-section of the corresponding recess can be rotationally asymmetric in order to form the symmetry-breaking interface.

[0050] The projection and / or recess may additionally or alternatively feature retaining elements, such as locking lugs. The locking lugs can engage a shoulder, thus enabling a secure plug connection between the disassembly stage and the support with the flow obstructions.

[0051] In practice, it may further be provided that the

[0052] The outlet step is supported by the disassembly step. This support can be achieved, for example, by the outlet step being integrally formed with the disassembly step via the support. Alternatively, the outlet step can be supported by connecting it to the disassembly step via the support. Apart from this, the outlet step can be unattached, but it doesn't necessarily have to be, as described below. In other words, apart from the connection via the support, the outlet step can float freely in its intended position within a sanitary fitting. In particular, in this case, the outlet step can have a free outer circumferential edge, i.e., one not fixed to another component. The geometry of the outlet step can therefore be flexibly designed, especially at the circumferential edge.In other words, in this case an outer contour of the outlet stage can be formed independently of an inner contour of a housing surrounding the outlet stage and / or of an inner contour of an element surrounding the sanitary insert, for example a mouthpiece.

[0053] Additionally or alternatively, in practice, the flow obstructions can be forcibly aligned with the positions of the holes in the separating stage for a passing fluid. In particular, the flow obstructions can be forcibly aligned with the positions of the separating nozzles in the separating stage. A reproducible alignment of the holes from which the individual jets of the separating stage emerge, relative to an orientation of the flow obstructions, can be advantageous for consistent jet generation quality across many aerators. This forced alignment can eliminate the degree of freedom that normally arises when using inserts as flow obstructions in the prior art. Additional alignment aids, such as guide grooves, guide ribs, or other shapes on inserts, are unnecessary.This can also facilitate largely automated manufacturing.

[0054] Particularly when the support can be connected to the disassembly stage, the support connection can be designed to achieve forced alignment such that the flow obstructions can be arranged in a single predetermined orientation or in two predetermined orientations, in which the flow obstructions are forced to align with the positions of the holes in the disassembly stage. In particular, the shape of the described recess in the disassembly stage and the shape of the corresponding projection of the support can be designed accordingly, for example, having a symmetry-breaking interface with a predetermined orientation.

[0055] As mentioned, the separation stage can be designed as a separation plate. The resulting flat arrangement of holes is particularly easy to align with flow obstructions.

[0056] Furthermore, it can be advantageous if the arrangement of the holes in the separation stage in the main flow direction is congruent with a shape of the flow obstructions. This allows the holes to be easily covered by subsequent flow obstructions.

[0057] Additionally or alternatively, it can be provided that at least some of the flow obstructions, in particular the flow obstructions, are forcibly aligned centrally with the positions of holes in the separation stage for a passing fluid. For example, a flow obstruction can be forcibly aligned with each hole of the separation unit in such a way that the fluid passing through a hole as intended, for example water, strikes the flow obstruction centrally. Deep penetration of the emerging individual jets into the mixing chamber is thus avoided.

[0058] The aforementioned holes can each be configured as an outlet for the fragmentation nozzles of the fragmentation stage. This allows for the simple predefining of the outflow directions of the individual jets, making alignment even more feasible.

[0059] In particular, the holes of the separation stage can be arranged in at least one row. In this case, a flow obstruction can be oriented towards each row of holes, and especially towards each row of separation nozzles, such that the fluid passing through the holes as intended encounters the flow obstruction. One or more flow obstructions of the mixing stage can, for example, be arranged parallel to and preferably in the main flow direction below one of the at least one row, particularly centrally. This also results in the described advantage that deep penetration of the emerging individual jets into the mixing chamber is avoided.For this purpose, especially if the carrier can be connected to the disassembly stage, the interface can be designed such that the arrangement of the flow obstructions can be arranged in a single predetermined orientation or in two predetermined orientations, in which at least one of the flow obstructions is arranged below and parallel to one of the at least one row of holes.

[0060] Additionally or alternatively, it can be provided that a flow obstruction, particularly in an uppermost level, is oriented towards each hole of the separation stage such that the water exiting the hole preferably strikes the flow obstruction centrally. In practice, it can further be provided that at least the mixing stage is laterally enclosed by a sleeve-shaped housing part. The housing part can also laterally enclose the mixing stage and the separation stage, or the mixing stage and the outlet stage, or the mixing stage, the separation stage, and the outlet stage. This can, for example, be the case over the entire length between the separation stage and the outlet stage, particularly an outlet structure.Thus, for example, the interior of the mixing stage, i.e., in particular a space or system of spaces accommodating flow obstructions, can be closed or delimited upstream by the separation stage, downstream by the round outlet stage, and laterally by the sleeve-shaped housing part. This allows for a compact or at least enclosed insert.

[0061] The sleeve-shaped housing part can be geometrically matched to the round outlet stage, in particular such that an outer contour of the outlet stage, as described here, abuts an inner contour of the housing part, as described here. The geometric match can additionally or alternatively be designed such that the circumferential gap between the outlet stage and the housing part remains essentially constant. This allows the support with the flow obstructions and the outlet stage to be inserted into the housing part particularly easily and / or with a precise fit, enabling the emission of a defined jet.

[0062] Additionally or alternatively, the disassembly stage can be enclosed laterally by the housing part.

[0063] In practice, the housing part can preferably be permanently connected to the disassembly stage via a disassembly stage connection. The disassembly stage connection can be force-fit and / or form-fit. In particular, the preferably permanent disassembly stage connection can be captive. The permanent connection of the housing part to the disassembly stage can, in particular, be detachable only by destructive means. If required, it can also be provided that the disassembly stage can be detachably connected to the housing part.

[0064] If the disassembly stage can be connected to the housing part, it is possible to combine different housing part variants with different disassembly stage variants. Furthermore, if the disassembly stage and the carrier can be connected to each other, as described, it is also possible to flexibly and easily combine different housing part variants with different disassembly stage variants, as well as with different flow restrictors and / or different discharge stages. Another advantage is that the disassembly stage can be manufactured separately from the housing part. This can simplify tool design for injection molding. With a detachable disassembly stage connection, the aforementioned combination can be modified subsequently, allowing for adaptation to changing requirements while minimizing waste.In the case of an inseparable decomposition stage connection, it is advantageous that a particularly undesirable loosening or subsequent replacement of components of the combination can be prevented.

[0065] If the separation stage connection is designed as a captive connection, it can be, in particular, a latching connection and / or a snap-fit ​​connection. Specifically, the housing part can have at least one retaining projection extending inwards into an interior space, especially the described interior space of the mixing stage. The separation stage can then rest on one side of the retaining projection in the main flow direction. The separation stage can be placed onto this side from an inflow side of the housing part. Alternatively, the separation stage can be inserted into the housing part from an outflow side and moved past the at least one retaining projection.In the latter alternative, the disassembly stage, when moved past the at least one retaining projection, can be elastically deformed, at least in sections, and spring back elastically to its original shape on the upstream side of the retaining projection. For this purpose, the at least one retaining projection on the downstream side can be wedge-shaped, i.e., with a wall rising inwards in the insertion direction. The disassembly stage can have an elastic ring, particularly a circumferential one. In particular, a retaining projection circumferentially on the inner surface of the housing part can be formed. Due to the circumferential ring and / or the circumferential retaining projection, a particularly secure connection of the disassembly stage to the housing part can be achieved.

[0066] To seal the separation stage, which is connectable to the housing part, against the mixing stage, a gap, particularly on the inlet side, between the housing part and the separation stage can be sealed with a sealing element, in particular a gasket, preferably a sealing ring. The sealing element can be clamped in the housing part and / or rest on the separation stage. This ensures that the sealing element is held securely in its intended position.

[0067] As an alternative to the jointable design of the housing part with the disassembly stage, the housing part can, in practice, be formed integrally with the disassembly stage. This makes it possible to easily arrange the disassembly stage and the housing part together, for example, in the outlet of a sanitary fitting or in a nozzle. If the housing part is formed integrally with the disassembly stage, and the disassembly stage is also formed integrally with the support, it is possible for the disassembly stage, the housing part, the support with the flow obstructions, and the outlet stage to be easily arranged together in the outlet of a sanitary fitting. This allows at least one main element of the sanitary fitting to be formed from a single piece, which is particularly stable and easy to install.

[0068] Alternatively, if the housing part is formed in one piece with the disassembly stage and the support is designed to be connectable to the disassembly stage, it is possible to first arrange the disassembly stage and the housing part together in a simple way in an outlet piece of a sanitary fitting and then to connect the support with the flow obstructions and the outlet stage together with the disassembly stage and arrange it in the sanitary fitting.

[0069] The housing part can have an external fastening element, for example, in the form of a preferably circumferential retaining projection, which can engage with a counter-fastening element of a connection part and / or a nozzle. Alternatively or additionally, the fastening element can be a thread formed on the outside of the housing part, in particular an external thread, with which the housing part can be screwed into a connection part and / or a sanitary fitting. The fastening element can be located, in particular, on the inlet side of the outlet stage and / or on the outflow side of the separation stage. The connection part and / or the sanitary fitting can have a corresponding counter-fastening element, for example, in the form of an internal thread. The housing part can, for example, be made of plastic.The housing part can, for example, separate the mixing stage from an air intake chamber through which air can be supplied.

[0070] In practice, it may additionally or alternatively be provided that the housing part has an inner surface whose inner contour surrounds a non-circular flow cross-section. In other words, the contour of the inner surface determines the non-circular flow cross-section. The inner surface refers to the interior side of the housing part facing the interior. In particular, the inner contour of the inner surface may surround a non-circular flow cross-section of the mixing stage and / or the discharge stage. If an outer contour of the flow obstruction arrangement and / or an outer contour of the discharge stage corresponds to the inner contour of the inner surface, it is possible to arrange the flow obstruction arrangement in preferred orientations with respect to rotations about a longitudinal axis parallel to the main flow direction, in particular the longitudinal axis described above, within the housing part.The non-circular inner contour can be, for example, triangular, square, pentagonal, hexagonal, octagonal, oval, or elliptical. With an octagonal outer and inner contour, for instance, it is possible to reduce the number of possible orientations from essentially infinite to eight preferred orientations, compared to a circular outer and inner contour.

[0071] If the housing part can be connected to the disassembly stage via the disassembly stage connection, in practice the disassembly stage connection may be designed to have a non-symmetrical and / or non-circular interface. This interface can define an orientation of the housing part relative to the disassembly stage with respect to rotations about a longitudinal axis that is aligned parallel to the main flow direction, in particular the longitudinal axis described above. This allows for a unique orientation of the disassembly stage and the housing part relative to each other.

[0072] For example, the disassembly stage can have a plurality of pins, in particular arranged circumferentially and / or at intervals. The housing part can have recesses corresponding to the pins, into which the pins engage when connected. For the interface, for example, one of the pins and its corresponding recess can be longer and / or wider than the other pins and their corresponding recesses, so that the longer and / or wider pin can only be connected to the disassembly stage in one orientation of the housing part relative to the disassembly stage.

[0073] In practice, it may additionally or alternatively be provided that an outer contour, in particular the outer contour described here, of the outlet stage corresponds to an inner surface of a housing part, in particular to the inner surface of the housing part described here. In particular, the outlet stage may be designed as an outlet structure, preferably the one described here, and an outer contour of the outlet structure may correspond to an inner surface of a housing part, in particular to the inner surface of the housing part described here. The inner surface may, in particular, be an inner surface of a downstream section of a housing part, in particular of the housing part described here.

[0074] Due to its corresponding design, the outlet step can be used particularly easily. Additionally or alternatively, an attractive appearance can be created for the sanitary fitting and / or a water jet that can be discharged with the sanitary fitting.

[0075] The outer contour can be formed, for example, as a circumferential edge or by components of a lattice structure. For instance, the inner surface and its corresponding outer contour can be aligned and / or complementary. If the outer contour is also formed as a circumferential edge, it can be ensured that little or no water flows between the inner surface and the circumferential edge that is intended to be in contact with it.

[0076] Preferably, a sealant, in particular a sealing ring, can be arranged on and / or in a gap between the inner surface and the outer contour, which is designed in particular as a circumferential edge. This makes it possible for very little or no water to flow between the inner surface and the circumferential edge.

[0077] In practice, it may further be provided that a clear width of a housing part, in particular of the housing part described here, is as large as or larger than a core width of a fastening means of the housing part, in particular of the fastening means described here, with which the sanitary insert part can be fastened as intended to a counter fastening means, in particular of the counter fastening means described here.

[0078] The clear width of the housing part can, for example, be an inner diameter of the housing part.

[0079] In particular, it can be provided that a clear width, preferably an inner diameter, of the described downstream section of the housing part is as large as or larger than the core width of the fastening means of the housing part.

[0080] The core width of the fastener is the width that the counter-fastener has as its clear width.

[0081] The fastening element can, for example, be designed as an external thread, in particular the external thread described here. In this case, the mating fastening element can be an internal thread, in particular the internal thread described here.

[0082] If the fastener is designed as an external thread, in particular an external thread, the core diameter is the core diameter of the external thread, which corresponds to the clear width of the internal thread. The core diameter is the distance between the thread root, i.e., the lowest point of the external thread, and the opposite thread root. The core diameter is the smallest diameter occurring on the external thread.

[0083] The described design of the widths, in particular the diameters, results in the fastening element, for example designed as an external thread, being able to be screwed into the counter-fastening element, for example designed as an internal thread, and in the fact that downstream of the fastening element a maximum utilization of a width, in particular a diameter, of the outlet structure and thus an outlet jet with the largest possible flow cross-section can be achieved.

[0084] In particular, the width, especially the diameter, of the outlet structure can be as large as or larger than the core width of the fastener, especially the core diameter of the external thread. For example, the width of the outer contour of the outlet structure can be as large as or larger than the core width of the fastener.

[0085] Preferably, the wall thickness, particularly of the downstream section of the sleeve-shaped housing part described here, can be reduced compared to an adjacent upstream section of the housing part in order to achieve the described maximum utilization of the diameter of the outlet structure. For this purpose, the inner surface of, for example, the downstream section can be offset radially outwards relative to the inner surface of the adjacent upstream section.

[0086] In connection with the described design of the dimensions, particularly the diameters, it can be advantageous to provide that, downstream of the fastening element, especially the external thread, no ventilation channel of the type described below is formed that runs past an outer surface of the housing part. This allows the installation space otherwise required for the ventilation channel to also be used for the outlet structure. Additionally or alternatively, it can be advantageous if a water jet emitted by the sanitary insert is vented through the connection part or through an outlet piece of a sanitary fitting.

[0087] In practice, it may additionally or alternatively be provided that the outlet stage, which is designed in particular as the outlet structure, is supported by a housing part, in particular by the housing part described here.

[0088] The discharge step can be carried by means of the housing part in addition to, or as an alternative to, the described method of carrying the discharge step using the support connected to the disassembly step. In particular, when the discharge step is carried by the housing part, the discharge step is not formed integrally with the support and the disassembly step. Carrying the discharge step by means of the housing part provides an alternative to the described method of carrying it using the disassembly step, and this alternative makes the discharge step particularly easy for a user to operate as intended.

[0089] It is also possible that the outlet stage is supported by the housing part and, via the carrier, by the disassembly stage. This can result in a particularly stable sanitary insert.

[0090] In practice, it can also be provided that the discharge stage, which is designed specifically as the discharge structure, can be connected to a housing part, particularly the housing part described here, via a discharge stage connection. This makes the described support of the discharge stage by the housing part particularly easy. Additionally or alternatively, it is possible to flexibly and easily combine different variants of housing parts and / or disassembly stages with different variants of discharge stages. A further advantage is that the discharge stage can be manufactured separately from the disassembly stage and / or the housing part. This can simplify tool design for injection molding.

[0091] Preferably, the outlet stage can be permanently connected to the housing part.

[0092] The outlet step connection can be force-fit and / or form-fit. In particular, the preferably fixed outlet step connection can be captive, for example, with a clip connection. The fixed connection of the outlet step to the housing part can, in particular, be detachable only by destructive means. This is advantageous because it prevents unwanted loosening or subsequent replacement of components of the assembly. If required, it can also be provided that the outlet step can be detachably connected to the housing part, so that changes in requirements can be accommodated and waste is minimized.

[0093] If the outlet step connection is designed as a captive connection, the outlet step connection can in particular be a latching connection and / or a snap connection.

[0094] In practice, the outlet stage connection may further be designed to have a non-symmetrical and / or non-circular interface. In particular, this interface may define an orientation of the flow obstructions relative to the separation stage with respect to rotations about a longitudinal axis parallel to the main flow direction. As described, the housing part may also be connected to the separation stage in a predetermined orientation relative to the separation stage or be formed integrally with the separation stage.

[0095] Due to the fixed connection of the discharge stage to the support, which preferably determines a predetermined orientation of the flow obstructions relative to the discharge stage, and provided the housing part is arranged in a predetermined orientation relative to the disassembly stage, aligning the flow obstructions with a pattern or arrangement of holes in the disassembly stage can be easily achieved without requiring subsequent inspection or increased assembly effort. Thus, similar to the interface of the support connection, it is easy to ensure that the disassembly nozzles and flow obstructions align automatically, or that the disassembly nozzles and flow obstructions are precisely aligned with each other.

[0096] The interface of the support connection and the interface of the outlet stage connection can be present simultaneously, in which case they result in the same alignment of the flow obstructions with a pattern or arrangement of holes in the disassembly stage. Alternatively, only one of these two described interfaces may be present.

[0097] In practice, it may additionally or alternatively be provided that the outlet step connection and / or the interface of the outlet step connection is formed between an outer contour of the outlet step, in particular the outer contour described here, preferably the circumferential edge described here, and a section of an inner surface, in particular the described inner surface, of the housing part. In particular, the outlet step connection and / or the interface of the outlet step connection may be formed between the outer contour and the inner surface of the downstream section of the housing part.

[0098] For example, the outer contour, in particular the circumferential edge, can be non-circular, especially rotationally asymmetrical, for example elliptical or oval. The section of the inner surface on which the outlet step is arranged, or a sealing element arranged in this section, can be designed to correspond to, in particular complementarily to, the outer contour. In this way, the outlet step connection and / or the interface can be designed to be particularly simple and space-saving. In particular, in addition to the outer contour, which is preferably designed as a circumferential edge, no additional components or geometries may be required to form the interface.

[0099] In practice, it may additionally or alternatively be provided that a housing part, in particular the housing part described here, is designed with a double wall. The double wall may be designed to influence the ventilation of a water jet emitted by the sanitary insert, as described in more detail below. The double wall may, in particular, have an outer wall and an inner wall spaced apart from it. For example, the outer wall and the inner wall may be arranged coaxially. The outer wall and the inner wall may be formed integrally and / or firmly connected to each other by means of webs arranged between them. The outer wall may, for example, have a round outer surface. It may additionally or alternatively have a round inner surface. The inner wall may, for example, have a non-round outer surface.It may additionally or alternatively have a non-round inner surface, in particular the one described here.

[0100] In practice, it may additionally or alternatively be provided that the orientation of the flow obstructions relative to the separating stage with respect to rotations about a longitudinal axis parallel to the main flow direction is randomized. In other words, a defined orientation of the flow obstructions relative to the separating stage with respect to rotations about the longitudinal axis may be omitted, particularly if a sufficient number of holes are included in the separating stage. In this case, the sanitary insert can do without interfaces of the type described here.

[0101] It has been surprisingly discovered that, in sanitary fittings of a design known in technical terms as the "high-flow" variant, aligning the flow obstructions with the holes in the disassembly stage is not necessary, or at least not required with a high degree of precision. It has also surprisingly been found that, particularly in sanitary fittings of a design known in technical terms as the "low-flow" variant, aligning the flow obstructions with the holes or disassembly nozzles in the disassembly stage, and especially the alignment described here, can be advantageous.

[0102] A high-flow variant can be distinguished from a low-flow variant, for example, by its high or higher flow rate class. For instance, an aerator with dimensions 16.5 x 1 (thread diameter and thread pitch), which produces a jet diameter of 11 mm, can operate in high-flow mode from a flow rate class of 5 l / min, and an aerator with dimensions 24 x 1, which produces a jet diameter of 18 mm, from a flow rate class of 12 l / min. More generally, or additionally, one can say that the high-flow mode differs from the low-flow mode in that, in a high-flow mode, the individual jets encountering a flow obstruction are deflected so strongly that they interfere with neighboring jets, in particular deflecting and / or atomizing them, whereas this cannot occur in the low-flow mode.This can mean that aligning the flow obstructions with the dispersing nozzles is more important in low-flow mode and / or for low-flow sanitary components, especially low-flow aerators, than in high-flow mode and / or for high-flow sanitary components, especially high-flow aerators. For example, a flow rate per unit of time can be defined using an upstream reduction stage, especially a flow regulator, which results in operation in either the low-flow or high-flow mode. However, arrangements and designs of flow obstructions in the mixing stage are also possible that achieve good or even excellent jet characteristics for all flow classes.

[0103] For example, tests have shown that a suspended attachment or design of the flow obstructions or the associated support of the mixing stage on the separation stage can be used for all flow classes and thus especially for the low flow regime and the high flow regime.For example, tests have also shown that if the flow obstructions of the mixing stage are aligned with the separation nozzles of the separation stage via an orientation aid formed on the housing and / or between the support of the flow obstructions and the separation stage and / or the outlet stage, the sanitary insert can be used in a wide range of flow classes, for example in the low flow regime and / or in the high flow regime, in particular both for variants in which the flow obstructions are formed separately from the separation stage and for variants in which the flow obstructions are firmly connected to the separation stage.

[0104] Alternatively or additionally, to solve the aforementioned problem, the features of the further dependent claim, which also relates to a sanitary insert, may be provided. In this case, to solve the aforementioned problem, it is proposed according to the invention that the mixing stage has a sleeve in a sanitary insert of the type described at the outset or in a sanitary insert of the type described above. The sleeve can, in particular, be inserted into and / or attached to the mixing stage, especially such that it laterally surrounds the flow obstructions. Additionally or alternatively, the sleeve can be enclosed laterally spaced by a housing part, in particular the housing part described herein. Insertion and / or attachment is particularly possible if the support of the mixing stage can be connected to the separation stage and / or to the discharge stage.

[0105] Due to the sleeve, which can be flexibly used and / or removed, it is possible to flexibly and precisely influence the water jet dispensed by the insert. For example, the sleeve can be used to direct the water flowing into the mixing stage through a flow cross-section predetermined by the sleeve, whereby the flow cross-section can be smaller and / or geometrically different from the flow cross-section of the mixing stage. Additionally or alternatively, the sleeve can be designed to influence the aeration of the water jet, as described in more detail below.

[0106] Alternatively or additionally, the features of the further dependent claim, which also relates to a sanitary insert, can be provided to solve the aforementioned problem. According to the invention, to solve the aforementioned problem, it is proposed that a sanitary insert of the type described at the outset or of the type described above be provided with at least one ventilation passage leading into the mixing stage. This allows air to be supplied to the mixing stage to generate an aerated jet. The ventilation passage can be configured in particular if the sanitary insert has a housing part, especially the housing part described above, that laterally surrounds the mixing stage. The ventilation passage can open to the outside via an air inlet, particularly into an environment surrounding the sanitary insert. This allows air to be easily supplied to the mixing stage from the outside.

[0107] The ventilation passage can, in particular, lead at least partially or completely through the housing part or at least partially or completely along a housing part, for example the one already mentioned, for example parallel to the main flow direction between the described outer wall and the described inner wall, and / or transverse to the main flow direction.

[0108] Additionally or alternatively, the ventilation passage can lead through and / or along a sleeve that can be inserted into and / or attached to the mixing stage, in particular the sleeve described here, at least partially or completely.

[0109] Additionally or alternatively, the ventilation passage can lead past an inner surface of the housing part, in particular the inner surface of the housing part described here, and / or past an outer surface of the housing part.

[0110] Additionally or alternatively, the ventilation channel can run along an outer surface of the sleeve. This can be particularly advantageous if the ventilation channel also runs along the inner surface of the housing part. In this case, an annular or sleeve-shaped ventilation channel can be formed in the mixing stage outside the sleeve. Water can then flow inside the sleeve. The sleeve can also have openings or recesses to direct incoming air to or near the separation stage, such as the aforementioned separation stage, and its separation nozzles.

[0111] In practice, the sleeve may be supported by the flow obstructions and / or by the outlet stage, which is designed specifically as an outlet structure. For example, for this purpose, an inner contour of the sleeve can be connected to an outer contour of the arrangement of flow obstructions by means of a press fit. Additionally or alternatively, the sleeve can rest on the outlet structure.

[0112] In practice, the ventilation passage may also be provided for, at least in sections, by at least one ventilation opening. At least one of the at least one ventilation opening may, in particular, be formed in or on the housing part. Additionally or alternatively, at least one of the at least one ventilation opening may be formed in or on the sleeve. The at least one ventilation opening may, in particular, be designed such that an airflow perpendicular to the main flow direction of the water jet is possible. The at least one ventilation opening may, for example, be designed if the housing and / or the sleeve has a crown, i.e., an uneven end face, at an inflow-side end where the housing and / or the sleeve abuts the dispersing stage. Air can thus flow through the ventilation opening between the crown and the outlet stage.Additionally or alternatively, the at least one ventilation opening can be at least one window in the housing and / or the sleeve.

[0113] Thus, air can be supplied directly to the mixing stage. The at least one ventilation opening can extend, in particular, in a circumferential direction of the sanitary insert, so that the air can be supplied directly to the mixing stage along this length. Additionally or alternatively, a plurality of ventilation openings can be formed in the housing. This allows the direct supply of air to be further distributed and thus improved.

[0114] If the sanitary fitting has a ventilation opening, it can be provided in practice that the at least one ventilation opening is located on the upstream side of a floor in which the flow obstructions are arranged, in particular on the upstream side of the first floor of the described at least two floors. This allows for a particularly effective mixing of an incoming fluid, especially water, with the air flowing in through the at least one ventilation opening, without the fluid, especially water, unintentionally escaping through the ventilation openings.

[0115] In particular, the positioning of at least one ventilation opening can meet at least one of the following criteria:

[0116] • The distance between the ventilation opening and the first level on the inflow side is at least 0.3 mm, preferably at least 0.5 mm; • The distance between the ventilation opening and the first level on the inflow side corresponds to at least one quarter of the distance from the disassembly stage to this level;

[0117] • The distance between an outflow-side end of the ventilation opening and the separation stage corresponds to at least a distance from a hole of the separation stage located transversely, in particular orthogonally, to the main flow direction to an edge of the separation stage. Depending on the size of the sanitary fitting and the respective operating conditions, the aforementioned criteria can ensure that the fluid, in particular the water, does not splash out of the at least one ventilation opening, or only to a limited extent, when the fluid encounters flow obstructions, and / or that the fluid, in particular the water, does not flow out of the at least one ventilation opening, or only to a limited extent, when the sanitary fitting is inclined during operation and the fluid pressure, in particular the water pressure, is low.

[0118] The ventilation passage can additionally or alternatively be formed, at least in sections, by an annular space, which is fluidically connected to the surroundings of the sanitary fitting, particularly via the air inlet, and can be formed around the entire perimeter of the mixing stage. The annular space allows for excellent air distribution and transport within the mixing stage.

[0119] In practice, it may additionally or alternatively be provided that at least one air channel is formed on one of the outflow sides of the separation stage, which is designed in particular as a separation plate, and which forms a section of the ventilation passage.

[0120] The ventilation passage can then be additionally or alternatively formed, at least in sections, by the at least one air duct. It has been shown that forming an air duct at the dismantling stage allows for a space-saving design of the sanitary installation, because the ventilation passage can then be formed, at least partially, within the material of the dismantling stage.

[0121] The air channel at the disassembly stage can be formed, for example, by modifying a (preferably flat or regular) base body with a three-dimensional structure to create air channels. For instance, an air channel can be formed by a depression or by limiting ribs. Preferably, the air channel is open at one end.

[0122] The at least one air channel can additionally or alternatively be configured longitudinally, in particular parallel, to the at least one row of holes of the disassembly stage. In particular, holes of the disassembly stage arranged in a common row can open into one of the at least one air channels. The row of these holes can be arranged along the air channel, in particular along the bottom of an air channel configured as a recess. In this case, if the holes of the disassembly stage are arranged in several rows, the rows can be separated by walls formed in the disassembly stage. These walls can, for example, be configured as ribs, in particular the aforementioned ribs.

[0123] Due to the arrangement of the holes in the air duct(s), water jets emerging from the holes can be excellently directed onto the flow obstructions arranged in the intended main flow direction under the recesses and simultaneously well aerated. Particularly good aeration can be achieved if the air duct(s) extend continuously from an outer circumference of the disassembly stage, especially with a constant cross-section, to a center point or centerline on the downstream side of the disassembly stage. Additionally or alternatively, the air duct(s) can extend from the outer circumference of the disassembly stage to the support connected to or integrally formed with the disassembly stage.

[0124] As mentioned, the separation stage can be designed as a separation plate with an arrangement of holes or separation nozzles. Thus, a typically flat underside of the separation stage can be used to form the at least one air channel as described. Since separation plates are also used at low operating pressures, the advantages of the invention are particularly beneficial here.

[0125] Preferably, the ventilation passage is designed such that the air flows from the air inlet through the annular space, then through the at least one ventilation opening, and then into the mixing stage. This allows for a compact design with excellent ventilation.

[0126] Alternatively or additionally, the features of the further dependent claim, which also relates to a sanitary insert, can be provided to solve the aforementioned problem. In this case, it is proposed according to the invention that, in a sanitary insert of the type described at the outset or in a sanitary insert of the type described above, no means for ventilation are provided. In contrast to the sanitary insert described here for generating an aerated jet, a sanitary insert can thus be provided with which an unaerated jet can be generated.

[0127] In practice, it may be provided that the mixing stage has at least two sub-spaces separated by the support, the support having at least one pressure equalization recess fluidly connecting the at least two sub-spaces.

[0128] The support can, in particular, be arranged in a plane with the described centerline of the downstream side of the separation stage. The two sub-spaces can thus be essentially the same size and preferably symmetrical.

[0129] The presence of at least one pressure equalization opening allows for pressure equalization between the sub-chambers. This means that any impairment of the jet cross-section caused by the support structure can be at least partially or completely compensated. Without the pressure equalization opening, the impairment can manifest itself in particular as a disruption of symmetry, for example, by a surface-shaped support structure, leading to the formation of a preferred flow direction in the cross-section. This causes the jet cross-section to deviate undesirably from the cross-section or cross-sectional shape of the mixing stage.

[0130] The pressure equalization recesses are particularly advantageous in the sanitary insert with round outlet step described here, because deviations from a round cross-section of a discharged water jet are particularly noticeable and, due to the pressure equalization recesses, a jet cross-section that is as round as possible can be produced when a water jet is discharged as intended.

[0131] The pressure equalization recess can, for example, define at least two fluid paths between the sub-chambers. This makes it possible to create circular flows, which counteract the aforementioned formation of a preferred direction in the jet cross-section and can thus help to generate a more homogeneous jet cross-section. It can be particularly advantageous if at least three or even more than three fluid paths are defined in this way. For example, this can be achieved by designing the pressure equalization recess as several pressure equalization openings that are not interconnected.

[0132] Each of the pressure equalization openings can then, for example, define a separate fluid path for equalization between the sub-chambers. The surface area of ​​the pressure equalization opening can, for example, be at least 10%, at least 15%, or at least 20% of the surface area of ​​a longitudinal section of the mixing stage. Thus, a substantial contribution to mixing across the separation of the two sub-chambers can be achieved. This effect can be particularly advantageous if at least 30% or even at least 40% of the surface area of ​​the longitudinal section is occupied. It is especially beneficial if the pressure equalization opening occupies as large a proportion as possible, while also taking into account the remaining stability of the support structure and the space required for flow obstructions.Particularly good results can be achieved in the 44-60% range, but pressure equalization recesses with at least 60% or even at least 70% surface area are also possible.

[0133] The at least one pressure equalization recess can, in particular, allow a transverse flow with respect to the main flow direction. The formation of a transverse flow has a balancing effect between the sub-spaces, which can result in a more uniform cross-sectional pattern of the emerging water jet.

[0134] In particular, this method makes it possible to avoid geometrically induced deformations of the jet cross-section using simple means. Specifically, it allows for a jet cross-section that is adapted as closely as possible to the clear cross-section or cross-sectional shape of, for example, the aforementioned mixing chamber or discharge stage, especially discharge structure.

[0135] In practice, the mixing stage may additionally or alternatively be provided with a support structure that braces the beam in the main flow direction. Additionally or alternatively, the mixing stage may also have a support structure that braces the arrangement of flow obstructions in the main flow direction. The support structure can serve to reduce or prevent deformation of the beam and / or displacement of the flow obstructions, particularly in the main flow direction. For this purpose, the support structure may, for example, have a plurality of webs that engage radially outward flow obstructions and / or radially outward points of flow obstructions. Webs are thin and thus have a minimal impact on the flow. At the same time, they are ideally suited for a predetermined force application.Additionally or alternatively, the webs can be arranged in a plane with the described centerline of the downstream side of the disassembly stage. This can be particularly advantageous if the support is also arranged in this plane.

[0136] In practice, the support structure, which may be designed as a plurality of webs, can be configured to support the beam and / or arrangement of flow obstructions at the outlet step. This configuration can be particularly advantageous because it allows the beam and / or arrangement of flow obstructions to be supported in the main flow direction or slightly inclined to the main flow direction. This results in particularly high stability of the support structure, allowing it to be designed with a very thin profile without compromising its support performance. Simultaneously, support at the outlet step can be advantageous because the beam and outlet step are formed as a single unit, and thus the support structure can be manufactured concurrently with the one-piece production of the beam and outlet step. The support structure can then also be formed as a single unit with the beam and outlet step.This makes the sanitary insert easy to manufacture overall and allows for particularly stable support.

[0137] Alternatively or additionally, the features of the further dependent claim, which also relates to a sanitary insert, can be provided to solve the aforementioned problem. In this case, it is proposed according to the invention that, in a sanitary insert of the type described at the outset or in a sanitary insert of the type described above, at least some of the flow obstructions have a non-circular cross-section. With non-circular cross-sections of the flow obstructions, a particularly good compromise between turbulence of the incoming jets and water throughput through the mixing stage can be achieved.

[0138] The non-circular cross-section can have a greater extent, particularly in the main flow direction and / or in a direction in which the sanitary fitting can be inserted into a sanitary fitting, than perpendicular to this direction. This allows the fluid, especially water, to exit the sanitary fitting as a particularly homogeneous jet in the main flow direction.

[0139] Additionally or alternatively, the non-circular cross-section can be elliptical or oval. This allows the flow obstructions to have a smooth surface, enabling particularly uniform mixing and water release.

[0140] If the flow obstructions are arranged on the support structure in at least two levels, particularly the at least two levels described here, it may be practical to provide that the flow obstructions in the upstream first of the at least two levels have a non-circular cross-section. Due to the non-circular shape in the first level, the influence of the flow obstructions on the fluid flowing around them in the first level can be reduced, thus reducing lateral splashing of the fluid, especially water.

[0141] Additionally or alternatively, particularly in the first of at least two floors on the upstream side, and further, particularly in the first of the at least two floors described here, the length ratio of the extent of the non-circular cross-section in the main flow direction and / or in the direction in which the sanitary insert can be inserted into a sanitary fitting, to the extent transverse to this direction, can be at least 1.5, preferably at least 1.8, and more preferably at least 2. With a length ratio of at least 1.5, preferably at least 1.8, and more preferably at least 2, the influence of the flow obstructions on the fluid flowing around them can be reduced. The influence decreases with increasing length ratio, thereby facilitating the flow around the obstructions. This allows the incoming fluid to be mixed in a controlled manner.

[0142] If the flow obstructions are arranged on at least two levels, in particular on the at least two levels described here, it may be additionally or alternatively provided in practice that the length ratio of the extent of a non-circular cross-section in the main flow direction to the extent perpendicular to this direction over two adjacent levels decreases.

[0143] Alternatively, it is also possible that the length ratio of the

[0144] The extent of a non-circular cross-section, in particular the one described here, increases in the main flow direction compared to the extent perpendicular to this main flow direction over two adjacent floors.

[0145] Due to the decrease and increase in length, it is possible to achieve a sanitary component with a small installation space. Additionally or alternatively, it is possible to create multiple zones in the mixing stage along the main flow direction, with a predetermined mixing of a fluid introduced as intended, particularly water, taking place in each of these zones. In particular, the length ratio across the levels can decrease or increase continuously, so that the mixing in the mixing stage increases or decreases continuously. A decrease in the length ratio between two adjacent levels can be particularly advantageous, as this allows for a gradually increasing mixing along the main flow direction.

[0146] Furthermore, or alternatively, it can be provided that the length ratio of the extent of a non-circular cross-section, particularly the one described here, is greater in the first and last levels of the at least two levels in the main flow direction than in an intermediate level. This allows the advantages described, achievable with the decreasing length ratio in the main flow direction, to be combined with a particularly good jet alignment produced by the last level.

[0147] In practice, it can additionally or alternatively be provided that the non-circular cross-section becomes wider or narrower across two adjacent levels of the at least two levels in the main flow direction. This allows the described changes in length ratios to be achieved particularly easily. To solve the aforementioned problem, the features of the further dependent claim, which relates to the use of an arrangement of flow obstructions to form a mixing stage, can also be provided. According to the invention, it is proposed that, when using the type described above, the support is rigidly connected to a discharge stage. This makes it possible to form a mixing stage in a particularly simple manner. In particular, the support can be integrally connected to the discharge stage. Thus, a mechanically particularly stable sanitary insert can be formed.The outlet stage can be round, so that a round jet, which is popular in practice, can be easily produced due to its use.

[0148] In particular, if the support and the separation stage can be connected, the support with the flow obstructions and the discharge stage can be arranged downstream of a separation stage when used.

[0149] Alternatively, especially if the support and the disassembly stage are formed in one piece, the support with the flow obstructions and the outlet stage can be arranged downstream of a disassembly stage when used.

[0150] In its use, it may be provided that the mixing stage is or will be laterally surrounded by a housing part. In particular, the separating stage may be connectable to the housing part or formed integrally with the housing part.

[0151] Due to the application, it is possible to flexibly and / or easily combine different variants of disassembly stages and / or different variants of housing parts with different variants of supports, different variants of flow obstructions and / or different variants of outlet stages.

[0152] In connection with the use, explicit reference is also made to the description of the other claimed items, in particular to the description of the sanitary fitting. The features and associated advantages described therein are transferable to the use accordingly as features and associated advantages.

[0153] To solve the aforementioned problem, the features of the further dependent claim relating to a method for forming a sanitary insert can also be provided. According to the invention, it is proposed that the method comprises the following steps to solve the aforementioned problem:

[0154] - Providing a breakup stage and an arrangement of flow obstructions projecting from a support rigidly connected to a discharge stage;

[0155] - Merging the carrier and the disassembly stage;

[0156] - Connecting the support to the breakup stage such that the support and the flow obstacles are arranged downstream of the breakup stage and that the flow obstacles are perpendicular to the main flow direction.

[0157] This makes it possible to flexibly and / or easily design a sanitary insert with different variations of disassembly stages and different combinations of supports, flow restrictors, and outlet stages. A further advantage is that the support with the flow restrictors can be manufactured separately from the disassembly stage.

[0158] The fixed connection between the support and the exit step can be achieved in particular by forming the support and the exit step as a single piece.

[0159] The outlet step can be round in particular.

[0160] The support and the separating stage can be joined, particularly against the intended main flow direction. This allows for a particularly simple design of the sanitary insert, even if the separating stage is already integrated into a sanitary fitting.

[0161] In connection with all the methods described herein, explicit reference is also made to the description of the other claimed items, in particular to the description of the sanitary fitting. The features and associated advantages described therein can be transferred analogously to the methods as method features and associated advantages.

[0162] To solve the aforementioned problem, the features of the further dependent claim relating to a method for forming a sanitary insert can also be provided. According to the invention, it is proposed that the method comprises the following steps to solve the aforementioned problem:

[0163] - Providing a housing part and a disassembly stage, wherein the disassembly stage is rigidly connected to a support and the support is rigidly connected to a discharge stage, wherein an arrangement of flow obstructions projects from the support;

[0164] - Joining the housing part and the disassembly stage;

[0165] - Connecting the disassembly stage to the housing section such that the support and flow restrictions are arranged downstream of the disassembly stage within the housing section, and that the flow restrictions are positioned perpendicular to the main flow direction. This makes it possible to flexibly and / or easily design a sanitary insert with different housing section variants and with different combinations of disassembly stage, support, flow restrictions, and outlet stage. A further advantage is that the housing section can be manufactured separately from the disassembly stage.

[0166] The fixed connection between the support and the exit step can be achieved in particular by forming the support and the exit step as a single piece.

[0167] The outlet step can be round in particular.

[0168] The housing part and the disassembly stage can be joined together, particularly against the intended main flow direction. This allows for a particularly simple design of the sanitary insert, even if the housing part is already integrated into a sanitary fitting.

[0169] To solve the aforementioned problem, the features of the further dependent claim, relating to a method for introducing an arrangement of flow obstructions into a sanitary fitting, may also be provided. In this arrangement, the flow obstructions project from a support that is rigidly connected, in particular integrally formed, with a particularly round outlet step. According to the invention, to solve the aforementioned problem, the method is proposed to comprise the following steps:

[0170] Insertion of the arrangement of flow obstructions into the sanitary fitting through the outlet opening of the sanitary fitting;

[0171] Securing the arrangement in the sanitary fitting.

[0172] This procedure allows the arrangement of

[0173] Flow obstructions can be introduced into the sanitary fitting particularly easily, even if the disassembly stage is already arranged in a sanitary fitting.

[0174] In practice, the following additional steps may be provided in the procedure for introducing an arrangement of flow obstructions into a sanitary fitting, whereby the procedure may then be a procedure for introducing a sanitary insert into a sanitary fitting:

[0175] - Inserting a disassembly step into the sanitary fitting;

[0176] - Fixing the disassembly stage;

[0177] - Connecting the support to the disassembly stage in the sanitary fitting in such a way that the support and the

[0178] Flow obstructions are located downstream of the breakup stage and that the flow obstructions lie perpendicular to a, in particular the, main flow direction.

[0179] In particular, the disassembly stage can first be inserted into the sanitary fitting and fixed there, and then the arrangement of flow obstructions can be inserted into the sanitary fitting and the support can be connected to the disassembly stage.

[0180] The method can be designed in such a way that the disassembly stage is inserted into the sanitary fitting through the outlet opening. This makes the method particularly easy to carry out, especially without having to disassemble the sanitary fitting.

[0181] The method can additionally provide that a housing part, in particular the housing part described here, is inserted into the sanitary fitting, especially through the outlet opening of the sanitary fitting. The disassembly stage can either be formed integrally with the housing part, and consequently the housing part with the disassembly stage is inserted, whereby the disassembly stage can be fixed by fastening the housing part in the sanitary fitting. Alternatively, the disassembly stage can be connectable to the housing part, whereby the housing part can be inserted first and then the disassembly stage can be inserted, whereby the disassembly stage can be fixed by connecting it to the housing part.

[0182] This method allows for particularly easy insertion of the sanitary insert into the sanitary fitting. Furthermore, it makes it possible to flexibly and / or easily design a sanitary insert with different variations of disassembly stages and different combinations of supports, flow restrictors, and outlet stages.

[0183] In particular, the procedure can be used to insert the sanitary insert described here into a sanitary fitting.

[0184] If the support is firmly connected, in particular in one piece, with a particularly round disassembly stage, the following steps may alternatively be provided in practice for the method of introducing an arrangement of flow obstructions into a sanitary fitting, whereby the method may then also be a method for introducing a sanitary insert into a sanitary fitting:

[0185] - Inserting the disassembly stage with the arrangement and the outlet stage into the sanitary fitting;

[0186] - Fixing the disassembly stage such that the support and the flow obstructions are arranged downstream of the disassembly stage and that the flow obstructions lie transversely to a, in particular the, main flow direction.

[0187] The method can be designed in such a way that the disassembly stage is inserted into the sanitary fitting through the outlet opening. This makes the method particularly easy to carry out, especially without having to disassemble the sanitary fitting.

[0188] The method can additionally provide that a housing part is inserted into the sanitary fitting, in particular through the outlet opening of the sanitary fitting. The separation stage can be connected to the housing part, whereby the housing part can be inserted first and then the separation stage can be inserted, the separation stage being fixed by connecting it to the housing part, for example, by means of a separation stage connection, and in particular by means of the separation stage connection described here. The support and the flow obstructions are then arranged downstream of the separation stage in the housing part.

[0189] This method also allows for particularly easy insertion of the sanitary insert into the sanitary fitting. Furthermore, it is possible to flexibly and / or easily design a sanitary insert with different housing component variants and different combinations of disassembly stage, support, flow obstructions, and outlet stage.

[0190] In particular, the procedure can be used to insert the sanitary insert described here into a sanitary fitting.

[0191] To solve the aforementioned problem, the features of the further subordinate claim relating to a series of sanitary fittings may also be provided. It is proposed that the series comprises at least two variants of sanitary fittings, each variant having an identical separation stage. The separation stage of both variants is connectable to a support arranged downstream of the separation stage, the support being rigidly connected, in particular integrally, to a downstream, in particular round, outlet stage. The first variant has a first arrangement of flow obstructions lying transversely to a main flow direction and projecting from a support, and the second variant has a second arrangement of flow obstructions lying transversely to a main flow direction and projecting from a support, different from the first.

[0192] An advantage of this design is that sanitary components, particularly aerators, can be easily designed to meet a wide range of requirements. For example, by combining the separator stage with different arrangements of flow obstructions positioned transversely to the main flow direction and projecting from the support, the spray pattern generated in the mixing stage and / or the aeration of the jet can be quickly and / or easily adjusted. A further advantage is that this process generates as little waste as possible.

[0193] In connection with the product series described here, explicit reference is also made to the description of the other claimed items, in particular to the description of the sanitary fittings. The features and associated advantages described therein are transferable to the product series by analogy as features and associated advantages of the product series.

[0194] To solve the aforementioned problem, the features of the further subordinate claim relating to a series of sanitary fittings may also be provided. It is proposed that the series comprise at least two variants of sanitary fittings, each variant having an identical housing part. The housing part of both variants is connectable to a disassembly stage arranged in the housing part, the disassembly stage being rigidly connected, in particular integrally, to a downstream support, the support being rigidly connected, in particular integrally, to a downstream round outlet stage.The first variant has a first arrangement of flow obstacles lying transversely to a main flow direction and projecting from the support, and the second variant has a second arrangement of flow obstacles lying transversely to a main flow direction and projecting from the support, which differs from the first.

[0195] Another advantage is that sanitary components, especially aerators, can be easily designed to meet a wide variety of requirements. For example, by combining the housing with different types of separator stages and arrangements of flow obstructions positioned transversely to the main flow direction and projecting from the support, the spray pattern generated in the mixing stage and / or the aeration of the jet can be quickly and / or easily adjusted. A further advantage is that this process generates as little waste as possible.

[0196] To solve the aforementioned problem, the features of the further dependent claim relating to a fluidic arrangement may also be provided. In this context, it is proposed according to the invention that, in a fluidic arrangement of the type described above, the connecting part has at least one air guide for supplying air from outside the connecting part into the receptacle.

[0197] The fluidic arrangement includes a connection part, which can be, in particular, the connection part described here. The connection part is provided with a hose connection and a receptacle for a sanitary insert. The hose connection serves to connect a separate hose or can be materially bonded, for example, by laser welding or other welding methods. The receptacle can, in particular, be a space that serves to accommodate a sanitary insert, especially the one described here, such as an aerator. The receptacle can, in particular, be open in one direction so that the sanitary insert, for example, the aerator, can be inserted. The receptacle and the hose connection are in fluidic communication, so that a fluid, in particular water, can flow from the hose connection into the receptacle.Thus, a sanitary insert and / or an aerator inserted into the receptacle can be supplied with the fluid, in particular water. Because the connecting part has at least one air conduit for supplying air from outside the connecting part into the receptacle, a fluid, in particular water, dispensed as intended by the fluidic arrangement can be supplied with air. In particular, it is not necessary for the sanitary insert and / or the aerator itself to have means for supplying air in order to generate the aerated jet.

[0198] The design of the air guide at the connection point has the advantage that a larger proportion of the available cross-section at the sanitary fitting can be used for water flow. This allows for larger jet diameters.

[0199] In connection with the fluidic arrangements described here, explicit reference is also made to the description of the other claimed items, in particular to the description of the sanitary insert. The features and associated advantages described therein are transferable to the fluidic arrangement as features and associated advantages of the fluidic arrangement. In practice, it may additionally or alternatively be provided that the air conduit includes an opening in a wall of the connecting part. With the opening in the wall, a structurally simple and, in particular, compact design of the air conduit is possible. This is because the connecting part regularly already has a wall to support the sanitary insert.By utilizing the openings in the wall, the wall can also serve to conduct air, so that the formation of separate components for conducting air is not necessary.

[0200] The air conductors may also include two or more openings in the wall of the connector. The wall described in this context may, in particular, be the wall of a sleeve-shaped section of the connector.

[0201] Furthermore, in practice, the air guides can be designed to draw air from the interior of a sanitary fitting that accommodates the hose connection. This advantageously eliminates the need for an opening on the downstream side of the fluidic arrangement. In particular, no opening for supplying air at an downstream end is required, especially no opening for supplying air to a sanitary insert and / or a flow regulator located in the receptacle. In this way, a jet of air can be generated that is ventilated in a manner invisible to the user of the fluidic arrangement. In particular, this allows for the design of a visually appealing sanitary fitting.

[0202] In practice, it may also be provided that the air conduits are designed to draw in air from an outlet opening, in particular the outlet opening described here, of a sanitary fitting.

[0203] In this way, even if the sanitary fitting lacks an interior space for air supply as described above, or if an interior space is unsuitable for air supply, an aerated jet can be generated. The air guides for drawing air from the outlet opening can be designed to be invisible, particularly to a user. The air guides for drawing air from an outlet opening can be designed, in particular, as a flowable partial annular cross-section and / or ring cross-section fluidly connected to the outlet opening. Additionally or alternatively, the air guides, in particular the partial annular cross-section and / or the ring cross-section, can be designed with the aid of the described sleeve-shaped section of the receptacle and / or an opening in a sanitary fitting in which the receptacle is arranged.

[0204] Furthermore, in practice, it may be provided that the air-conducting elements are formed on an inner surface that defines the receptacle. In particular, the air-conducting elements may be formed in a threaded area. The threaded area may be formed on the inner surface that defines the receptacle. The threaded area may, for example, be formed by the described internal thread of the connecting part.

[0205] In this way, even if the sanitary fitting lacks the described interior space for supplying air, or if the interior space is unsuitable for supplying air, an aerated jet can be generated. Here too, the air intake elements can be designed to be invisible to the user. These air intake elements can be designed, in particular, as a flowable partial annular cross-section and / or a ring cross-section. Additionally or alternatively, the air intake elements, especially the partial annular cross-section and / or the ring cross-section, can be designed using the described sleeve-shaped section of the receptacle and / or a housing part of a sanitary insert part and / or a sanitary fitting inserted into the receptacle.

[0206] In an advantageous design, the air guides can include a channel running in a wall of the connection part, for example, the one already mentioned, and / or on the outside of a wall, for example, the one already mentioned. This allows for a simple and / or compact air supply.

[0207] In an advantageous embodiment, a sanitary insert, in particular as described above and / or claimed below, and / or a jet regulator can be arranged or formed in the receptacle. Thus, jet shaping and / or a desired jet quality can be achieved at a water outlet of the fluidic arrangement.

[0208] In this case, a ventilation opening of the sanitary insert and / or the aerator can be in fluidic communication with the air channel of the connection part. Thus, the ventilation of a sanitary insert or an aerator formed or arranged in the housing can be easily supplied with air from the outside.

[0209] In an advantageous design, it may be provided that the hose connection is integrated into the housing.

[0210] The air duct is designed with a fluidically separating sealing element. This prevents operating pressure from causing leakage via the air duct at the hose connection.

[0211] For example, the sealing element can be integrally formed with the connection part and / or the sanitary insert. This can simplify assembly. Alternatively or additionally, the sealing element or another sealing element, for example as a sealing ring, can be arranged in the receptacle. This can simplify the tool design for manufacturing the assembly.

[0212] What these variants can have in common is that a sealing element, such as the one already mentioned, contacts the sanitary insert and the connection part. This makes the aforementioned fluidic separation easily achievable.

[0213] To solve the aforementioned problem, the features of the further dependent claim, which relates to the use of a connection part of a fluidic arrangement, may also be provided. According to the invention, to solve the aforementioned problem, the use of a connection part of a fluidic arrangement for supplying air from outside the connection part to a sanitary insert part inserted into a receptacle of the fluidic arrangement is proposed.

[0214] This makes it possible to generate an aerated jet using a sanitary insert, in particular the sanitary insert described here and / or an aerator, inserted into a sanitary fitting.

[0215] In particular, an aerated jet can be generated regardless of whether the sanitary fitting and / or the aerator itself has means for supplying air to a fluid, especially water, being dispensed as intended. In other words, an aerated jet can be generated by this use even if the sanitary fitting does not have means for supplying air.

[0216] In particular, the use described here may relate to the use of a connecting part of the fluidic arrangement described here.

[0217] In particular, the supply of air from outside the connection part to a sanitary insert part placed in a receptacle of the fluidic arrangement can take place via an interior of a sanitary fitting that accommodates the fluidic arrangement.

[0218] Additionally or alternatively, air can be supplied via an outlet opening, in particular the outlet opening of a sanitary fitting described here.

[0219] Additionally or alternatively, air can be supplied between the sanitary insert and an inner surface of the connection part that limits the intake.

[0220] Additionally or alternatively, air can be supplied through a wall of the connection part.

[0221] In connection with the use of the connection part described here, explicit reference is also made to the description of the other claimed items, in particular to the description of the sanitary insert. The features and associated advantages described therein are transferable, mutatis mutandis, as features and associated advantages of the use of the connection part.

[0222] The invention will now be described in more detail by means of exemplary embodiments, but is not limited to these. Further exemplary embodiments result from combining the features of one or more claims with each other and / or with one or more features of the exemplary embodiments.

[0255] The figures are described collectively below, where expedient. Structurally and / or functionally similar or identical components and functional units are designated with matching reference symbols and are not described separately again.

[0256] Figures 1 to 5 show the same embodiment of a sanitary insert designated as a whole by numeral 1, which is exemplified as an aerator. Figures 1 and 2 show the sanitary insert 1 in its intended use. The sanitary insert 1 is attached to a connecting part 2 in a spout 3, for example, on a spout pipe of a sanitary fitting (not shown). Figures 3 to 5 show the sanitary insert 1 in isolation from different perspectives, with a housing part of the sanitary insert omitted in Figure 5 for clarity.

[0257] For the fastening of the sanitary insert 1 shown in Figures 1 and 2, the connecting part 2 has, in a manner known per se, at least one retaining projection 4 which is attached to the outlet piece 3 by a corresponding recess or shoulder 5. The fastening of the connecting part 2 can be effected, for example, by inserting the connecting part 2 into the outlet piece 3 through an outlet opening 11 of the outlet piece 3, from which the water is intended to exit the sanitary fitting. The connecting part 2 can be elastically deformed so that the retaining projection can be moved past the shoulder 5 and rest in a recess above the shoulder.

[0258] There are also known variants where the connecting part has an external thread that can be screwed onto a corresponding internal thread formed on the outlet piece, or where the connecting part has an internal thread that can be screwed onto a corresponding external thread formed on the outlet piece. In these cases, the connecting part can, for example, be a nozzle.

[0259] The sanitary insert 1 has a housing part 8, a separating stage 6, a mixing stage 7 formed downstream of the separating stage 6 and a mixing stage downstream of the mixing stage

[0260] 7 formed, round discharge stage 19. In other words, the mixing stage 7 is fluidically subordinate to the separation stage 6, and the discharge stage 19 is fluidically subordinate to the mixing stage 7. A support 33 of the mixing stage 7 and the discharge stage 19 are rigidly connected to each other, the rigid connection being achieved by the support 33 being formed integrally with the discharge stage 19.

[0261] The housing part 8 is sleeve-shaped and serves to connect the sanitary insert part 1 to the connection part 2. For this purpose, the sleeve-shaped housing part has

[0262] 8 a fastening means designed as an external thread 12 on , which is screw-fastened to a corresponding counter-fastening means designed as an internal thread 13 of the connecting part 2 .

[0263] In further examples, this is, for instance, described as...

[0264] Internal threads 13 form counter-fastening means directly on the outlet piece 3, so that the sanitary insert part 1 can be connected directly to the outlet piece 3, in particular by means of the housing part 8, especially by screwing it on (see Fig. 21 and the associated description). A connecting part 2 is then not required.

[0265] The sleeve-shaped housing part 8 also serves to form the sanitary insert 1 as a compact, mechanically stable structure and to seal it off externally. As can be seen particularly in Figures 3 and 4, the housing part 8 extends from the separation stage 6 to the outlet stage 19, and the sleeve-shaped housing part 8 laterally encloses the mixing stage 7 along its entire length between the separation stage 6 and the outlet stage 19. This creates an interior space 10 of the mixing stage in which the flow obstructions 32 are accommodated. The interior space 10 is delimited upstream by the separation stage 6, downstream by the round outlet stage 19, and laterally by the sleeve-shaped housing part 8. In the illustrated embodiment, the separation stage 6 and the outlet stage 19 are also enclosed by the housing part 8.

[0266] The housing part 8 is mechanically connected to the disassembly stage 6 via an inflow-side area.

[0267] The separation stage 6 serves to separate an incoming fluid, especially water, into a multitude of individual jets. This allows flow conditions upstream of separation stage 6 to be fluidically decoupled from flow conditions downstream of separation stage 6.

[0268] The separation stage 6 is designed as a basic body with a three-dimensional structure in the form of a separation plate 6. However, other forms of the separation stage are also conceivable, for example in the form of a diffuser. To separate the incoming water, an arrangement of holes 27, which can be seen particularly in Figures 3 and 5, is incorporated into the separation plate 6, from which individual jets can emerge. The holes 27 are arranged in parallel rows 37 and, in the variant of the sanitary insert 1 described here, have identical, constant rectangular cross-sections in the direction of flow.

[0269] In alternative versions of the disassembly stage, the holes can have different cross-sections, for example round cross-sections, and / or cross-sections that vary in the direction of flow, so that they can be designed as nozzles.

[0270] The disassembly plate 6, when used as intended in Figures 1 and 2 with the sanitary insert 1, is arranged orthogonally to a direction 14 in which the sanitary insert 1 is intended to be inserted into the sanitary unit. As a result, the individual jets flow out of the holes 27 in a direction essentially opposite to this direction 14.

[0271] The connection between the disassembly plate 6 and the sleeve-shaped housing part 8 is achieved via a positive-locking, captive disassembly stage connection, which can be seen particularly in Figures 3 and 4. This connection allows different variants of housing parts to be combined with different variants of disassembly stages.

[0272] The disassembly step connection is designed as a snap-fit ​​connection, for which the disassembly plate 6 has a circumferential elastic ring 17 on a circumferential edge, which can be seen particularly in Figure 5, and the sleeve-shaped housing part 8 has a circumferential retaining projection 18 on its inside, which projects inwards into the interior space 10, and which can be seen particularly in Figures 3 and 4. The retaining projection 18 is wedge-shaped on its downstream side, i.e., it has a wall that rises inwards in the direction 14. This allows the disassembly plate 6 to be placed on the retaining projection 18 from a designated inflow side in the opposite direction 14 when the housing part 8 is not in use, or the disassembly plate 6 can be inserted into the housing part 8 in the direction 14 from an outflow side of the housing part 8 and moved past the retaining projection 18 when the housing part 8 is in use.When the disassembly plate 6 is moved past the retaining projection 18, the ring 17 is elastically deformed and springs back elastically to its original shape on the upstream side of the retaining projection 18 and then rests on the upstream side of the retaining projection 18.

[0273] To seal a gap 28 between the separating plate 6 and the housing part 8, a sealing element designed as a sealing ring 29 rests on the separating plate 6 and the gap 28 on the upstream side of the gap, as can be seen in Figures 3 and 4, and is clamped in the housing part 8. The mixing stage 7 is thus sealed against a space formed on the upstream side of the separating stage 6. The sealing ring 29 also seals the sanitary insert 1 against the connection part 2 by bearing with an upstream side against an downstream side of the connection part 2. The sealing ring 29 is not shown in Figure 5, but is nevertheless present in principle when the insert 1 is installed.

[0274] In an alternative version of the sanitary insert 1, the separation stage 6 is formed integrally with the housing part 8 (see Fig. 6 and the accompanying description). In yet another version, no housing part 8 is provided, and the separation stage 6 is inserted directly into the connection part 2 or into the outlet piece 3 (not shown), for example, via a connection according to the separation stage connection described here. The mixing stage 7 is formed by the support 33 arranged in the interior 10 and an arrangement 41 of flow obstructions 32 located transversely to the direction 14 in which the sanitary insert 1 is intended to be inserted into the outlet piece 3. The direction 14 is directed opposite to the intended main flow direction 25 in which the sanitary insert 1 is subjected to flow.Thus, the flow obstructions 32 protrude from the support 33 in such a way that they also lie perpendicular to the main flow direction 25.

[0275] As indicated in Figures 1 and 2, and particularly evident in Figure 4, the sanitary insert 1 has at least one ventilation passage 9 leading into the mixing stage 7.

[0276] The ventilation passage 9 serves to supply air to the mixing stage 7 in order to generate an aerated water jet. The ventilation passage 9 is supplied with air from an air volume in the outlet piece 3. Through a window in the connection part 2 (not shown in these figures, but an exemplary embodiment of which can be seen in Fig. 24), air flows from the air volume in the outlet piece 3 to the housing part 8 and along the housing part 8 to the ventilation openings 24 formed in the housing part 8, as shown in Fig. 4.

[0277] A total of four ventilation openings 24 are provided, of which only two are shown in Figure 4 due to the sectional view. The ventilation openings 24 form a section of the ventilation passage 9, and the window of the connection part 2 serves as an air inlet into which the ventilation passage 9 opens. The ventilation passage 9 passes through the housing part 8 via the ventilation openings 24. The ventilation openings 24 are located in an inflow area of ​​the mixing stage 7 upstream of the flow obstructions 32 and close to the separating plate 6, so that the water jets flowing into the mixing stage 7 can be thoroughly mixed with the air. Furthermore, the ventilation openings 24 extend in the circumferential direction of the sanitary insert part 1 to allow the air to be introduced in a distributed manner.In particular, the ventilation openings 24 are arranged on the upstream side of a first level 38 of the flow obstructions 32, which is described in detail below, and on the downstream side of the separation stage 6. A distance A between a downstream end of the ventilation opening 24 and the separation stage 6 corresponds to a distance B from a hole 27 of the separation stage 6, located transversely, i.e., orthogonally, to the main flow direction 25, to an edge of the separation stage 6, so that water does not spray and / or run uncontrollably out of the sanitary insert 1 through the ventilation openings 24 when the sanitary insert 1 is tilted and / or the water pressure is low.

[0278] In the interior space 10, a further section of the ventilation passage 9 is formed by an annular space running around the mixing stage 7 in the cross-sectional plane of the ventilation openings 24. The annular space allows air flowing in through the ventilation openings 24 to be excellently distributed and transported within the mixing stage 7.

[0279] Not shown in the figures, but conceivable, is a variant of the sanitary installation in which no means for ventilation are provided. For example, based on figures 1 to 5, the ventilation window 24 can be omitted, so that an unventilated jet can be generated.

[0280] Downstream of the annular space, the flow obstructions 32 are considered in the main flow direction 25 in at least two

[0281] The three floors, namely floors 38, 39, 40, are arranged. This allows for good mixing in a cascade-like manner when water flows through the sanitary inlet 1 as intended. At least two, namely all three floors, are involved.

[0282] 38, 39, 40 aligned parallel to each other. The flow obstructions 32 on the different levels 38,

[0283] 39 and 40 each have parallel orientations to one another, as can be seen, for example, in Figures 3 and 5. The flow obstructions 32 of the first level 38 and the third level 40 are located exactly one above the other in the main flow direction 25, and the flow obstructions 32 of the second level 39 are laterally offset from them. As can be seen particularly in Figure 4, each pair of adjacent levels overlaps by a small section in the main flow direction 25, with the overlap of the third level 40 with the second level 39 being somewhat greater than the overlap of the second level 39 with the first level 38. Thus, the levels 38, 39, and 40 are arranged in a nested arrangement.

[0284] The flow obstructions 32 are held in the described position by the support 33. The support 33 consists of a central, round pillar 53, which is rigidly connected to the separation plate 6, and a thin wall 54. In the variant described here, the wall 54 is oriented orthogonally to the flow obstructions 32 and is arranged in a common plane with a centerline of the outflow side 15 of the separation stage 6. The rigid connection of the support 33 to the separation stage 6 is achieved in the variant described here by forming the support 33 and the separation plate 6 as a single piece. However, variants of the arrangement 41 of flow obstructions 32 without the support 33 are also conceivable, or with a support 33 that is not formed as a single piece with the outflow stage 6, but is preferably rigidly connected to it.

[0285] Due to the central arrangement of the support 33 and the flat wall 54, the flow obstructions 32 can be supported by the support 33 particularly easily and effectively. Particularly high stability is achieved by the fact that the arrangement 41 of flow obstructions 32 is firmly connected to the support 33, in particular as a single piece.

[0286] Due to the wall 54 of the support 33, the mixing stage 7 is divided into two equally sized, symmetrical sub-chambers 34, 35. The wall 54 of the support 33 has a plurality of pressure equalization recesses 36, which fluidically connect the two sub-chambers 34, 35. The pressure equalization recesses 36 are so large that the essentially wall-shaped support 33 is reduced to the central pillar 53 and a plurality of flat webs that connect the flow obstructions 32 at specific points.

[0287] The pressure equalization recesses 36 allow a transverse flow with respect to the main flow direction 25. The formation of a transverse flow has a balancing effect between the sub-spaces 34, 35. In particular, pressure equalization between the sub-spaces 34, 35 is possible. Thus, any impairment of the jet cross-section that can be discharged as intended with the sanitary insert 1 by the support 33 can be at least partially compensated.

[0288] The pressure equalization recesses 36 are particularly advantageous in the sanitary insert 1 with round outlet stage 19 described here, because deviations from a round cross-section 30 of a discharged water jet are particularly noticeable and, due to the pressure equalization recesses 36, a jet cross-section that is as round as possible can be produced for a water jet discharged as intended.

[0289] The flow obstructions 32 have a non-circular cross-section 30, which can be seen particularly in Figures 3 and 4 and is realized in particular in the form of a rectangle with rounded corners. The non-circular cross-section 30 has a greater extent in the intended main flow direction 25, which is opposite to the direction 14 in which the sanitary insert 1 can be inserted into the sanitary fitting, than transversely, and in particular orthogonally, to this direction 25. The length ratio of the extent of the non-circular cross-section 30 in direction 25 to the extent transversely, and in particular orthogonally, to this direction 25 is at least 2. From the first floor 38 to the third floor 40, i.e., Over the floors adjacent along the main flow direction 25, this length ratio increases slightly because the extent of cross-section 30 perpendicular to direction 25 decreases and the extent of cross-section 30 in direction 25 remains unchanged.In other words, the cross-section 30 and thus also the flow obstructions 32 become narrower over two floors 38, 39 and 39, 40 respectively, adjacent in the main flow direction 25.

[0290] The non-circular cross-sections of the flow obstructions 32 allow for a particularly good compromise between turbulence of the incoming jets and water flow rate through the mixing stage 7. Furthermore, the water flowing along the aligned flow obstructions 32 through the mixing stage 7 can flow evenly out of the sanitary inlet section 1.

[0291] In other alternative variants of the sanitary insert 1, the cross-sections are elliptical or oval, as can be seen, for example, in Fig. 9 and Fig. 11.

[0292] The superimposed flow obstructions 32 of the first level 38 and the third level 40 are forcibly aligned with the positions of the holes 27 formed in the rows 37 of the separating plate 6 such that the water passing through the holes 27 as intended strikes a flow obstruction 32 of the first level 38 located parallel to one of the rows 37 of holes 27 in the center. The arrangement of the holes 27 in the separating plate 6 in the main flow direction 25 is congruent with the shape of the flow obstructions 32, so that the holes 27 can be easily covered by the subsequent flow obstructions 32. This prevents the individual jets emerging from the holes 27 from penetrating deeply into the mixing chamber 7.

[0293] A reproducible alignment of the holes 27, from which the individual jets of the separating plate 6 emerge, relative to an orientation of the flow obstructions 32, which can be achieved with the forced alignment, can be advantageous for a consistent quality of jet generation across many jet regulators.

[0294] To prevent or minimize deformation of the support 33 and the flow obstructions 32 under the load of the impacting water jets, the mixing stage 7 has a support structure 42 that braces the support 33 and the arrangement 41 of flow obstructions 32 in the main flow direction 25 at the outlet stage 19. As can be seen particularly in Figures 4 and 5, the support structure 42 is formed in the form of two thin, flat webs 42, which are arranged in a plane with the wall 54 of the support 33 and the described centerline of the downstream side 15 of the separation stage 6. The webs 42 engage radially outward flow obstructions 32 and are inclined radially outward when viewed in the main flow direction 25. For particularly high stability, the webs 42 are integrally formed with the support 33 on the upstream side. On the downstream side, the piers 42 rest on the outlet step 19.This allows the support 33 to be supported by the flow obstructions 32 as needed, or to swing freely with respect to the outlet step 19. The thin, flat webs 42 have only a very minor influence on the intended flow and are at the same time ideally aligned for a predetermined force input initiated by the water flow.

[0295] The outlet stage 19, as can be seen particularly in Figure 5, is an outlet structure 20 with a round outer contour 21, which is defined by a round circumferential rim 21. The outlet structure 20 has a lattice structure 22 and a plurality of openings 23 in a central section, wherein the lattice structure 22 has lattice elements aligned parallel to the main flow direction 25 for aligning the flow, and the openings 23 are honeycomb-shaped between them. In a radially outer ring section adjacent to the circumferential rim 21, the outlet structure 20 has larger, semi-annular openings 26. The circumferential edge 21 corresponds to an inner surface 60 of a downstream section 65 of the housing part 8 such that the circumferential edge 21 and the inner surface 60 of the downstream section 65 are complementary to each other, as shown in Figures 1, 2 and 4.

[0296] The flow obstructions 32 can be inserted into the housing part 8 with the outlet stage 19 and / or the disassembly stage 6, in the direction of flow (not shown) and / or against the direction of flow (as shown in the figures).

[0297] In this process, the disassembly stage 6 (for example via the ring 17) and / or the discharge stage 19 (for example via the outer contour 21) and / or the carrier 33 (not shown) can make sealing contact with the housing part 8.

[0298] For the one-piece formation of the mixing stage 7 with the discharge stage 19, the support 33 of the mixing stage 7 is formed integrally with the discharge structure 20 at one downstream end. Thus, the discharge stage 19 is also formed integrally with the separation stage 6, and the discharge stage 19 is supported by the separation stage 6 when the separation stage 6 is located in the housing part 8. The discharge stage 19, supported by the separation stage 6, does not require any further fastening, for example, to the housing 8 or a direct fastening to the separation stage 6. However, this is also possible as an option.

[0299] As can be seen particularly in Figure 4, the clear opening, in the form of an inner diameter 66, of the housing part 8 in the downstream section 65 is as large as the core diameter, in the form of a core diameter 67, of the external thread 12 of the housing part 8, with which the sanitary insert 1 is intended to be fastened in the connection part 2. The core diameter, i.e., the core diameter 67, of the external thread 12 corresponds to the clear opening of the internal thread 13 of the connection part 2. This allows the external thread 12 to be screwed into the internal thread 13 and, in addition, enables maximum utilization of the diameter of the outlet structure 20 downstream of the external thread 12. The diameter of the outlet structure 20 corresponds to the inner diameter 66 of the housing part 8 in the outflow-side section 65 due to the corresponding design with the inner surface 60 of the downstream section 65 .This allows for an outlet jet with the largest possible flow cross-section.

[0300] In the embodiment shown in Figures 1 to 5, the wall thickness of the downstream section 65 of the sleeve-shaped housing part is reduced compared to an upstream adjacent section of the housing part 8 in order to achieve the described maximum utilization of the diameter of the outlet structure 20. For this purpose, the inner surface 60 of the downstream section 65 is offset radially outwards relative to the inner surface of the upstream adjacent section.

[0301] Depending on the design of the sanitary facilities described here

[0302] The housing part 8 and the outlet stage 19 are not mandatory components of the sanitary insert.

[0303] Figure 6 shows an alternative version of the sanitary insert 1. This version is similar to the version shown in Figures 1 to 5. Therefore, only the existing differences between the two versions will be described below.

[0304] In the variant shown in Figure 6, the disassembly stage 6 and the housing part 8 are not connected to each other, but are formed in one piece. Therefore, the described disassembly stage connection is unnecessary. This one-piece design is particularly well sealed and mechanically stable.

[0305] To enable the support 33 to be inserted in the direction 14 in which the sanitary insert 1 is intended to be inserted into the sanitary unit, the support 33 in the variant shown in Figure 6 is not formed integrally with the disassembly stage 6, but rather the support 33 is connectable to the disassembly stage 6 via a support connection 43. This also makes it possible to flexibly and easily combine different variants of disassembly stages 6 with different variants of supports 33, different variants of arrangements 41 of flow obstructions 33, and / or different variants of outlet stages 19.

[0306] The carrier connection 43 is designed as a locking, captive connection.

[0307] The support connection 43 has a symmetry-breaking interface 44, where the interface 44 defines an orientation of the flow obstructions 32 relative to the disassembly stage 6 with respect to rotations about a longitudinal axis. Thus, an orientation of the flow obstructions 32 towards the rows 37 of the holes 27 in the

[0308] Disassembly stage 6 is accessible. For the symmetry-breaking interface 44, the disassembly stage, designed as disassembly plate 6, has a central, asymmetrical recess that can be accessed in an orientation parallel to the main flow direction 25. The carrier 33 has a projection geometrically corresponding to the recess and spring-loaded locking lugs 51 that engage the projection. The carrier 33 can thus be moved into the recess against the main flow direction 25 with the projection. Once the locking lugs 51 have penetrated the recess, they can spring open and thus securely hold the carrier 33 in the disassembly plate 6.

[0309] Alternative variants of the sanitary insert 1 with different types of support connection 43 are shown in Figures 14 and 15. These variants are similar to the variant shown in Figure 6, therefore only the existing differences are described. In particular, the housing part 8 is not shown in Figures 14 and 15 for better illustration of the respective support connection 43. The disassembly stage 6 shown in Figures 14 and 15 can either be connected to the housing part 8 analogously to the variant in Figures 1 to 5, or, analogous to the variant in Figure 6, be formed as a single piece with the housing part 8.

[0310] The support connection 43 shown in Figures 14 and 15 can function in a similar way. The support connections 43 shown can be designed as a latching connection.

[0311] The support connections 43 shown differ from each other in that the variant shown in Figure 14 allows free alignment and rotation of the support 33 and the arrangement 41 of flow obstructions 32 relative to the disassembly stage 6 about a longitudinal axis, whereas the variant shown in Figure 15, like the variant shown in Figure 6, determines a forced alignment of the support 33 and the arrangement 41 of flow obstructions 32 relative to the disassembly stage 6.

[0312] For the forced alignment of the support 33 and the arrangement 41 shown in Figure 15, the support 33, with its flat wall 54, engages in slots 46 oriented along the main flow direction 25 in two projections 47 of the disassembly plate 6. A section of the flat wall 54 and the slots 46 are geometrically corresponding to each other. This allows the support 33 to be easily inserted into the slots 46, particularly in the direction 14. The combination of the slots 46 and the support 33 forms the symmetry-breaking interface 44, which defines an orientation of the flow obstructions 32 relative to the disassembly stage 6 with respect to rotations about a longitudinal axis.

[0313] In the variant shown in Figure 14, the projections 47 with the slots 46 are also formed. However, the projections 47 protrude less from the disassembly plate 6 in the main flow direction 25 than in the variant shown in Figure 15. Thus, the support 33 does not engage with the slots 46. The support connection 43 is made exclusively via the central, round pillar 53 of the support 33, which is rotatably connected to a corresponding recess in the disassembly plate 6.

[0314] Figure 7 shows another alternative variant of the sanitary insert 1. This variant is also similar to the variant shown in Figures 1 to 5. Therefore, only the existing differences between the two variants will be described below.

[0315] The variant shown in Figure 7 features the support connection 43, which is described in connection with the variant shown in Figure 6. This variant can alternatively also feature the support connection 43 shown in Figures 14 or 15. Furthermore, the variant shown in Figure 7 features the separation stage connection described in connection with the separation stage described in Figures 1 to 5. This variant therefore differs from the variant shown in Figures 1 to 5 in that the separation stage 6 and the support 33 can be connected to each other. This allows for particularly high flexibility with regard to the combinability of different variants of separation stages 6, supports 33, arrangements 41 of flow obstructions 33 and / or discharge stages 19.

[0316] Figures 8 and 9 show another alternative variant of the sanitary insert 1. This variant is also similar to the variant shown in Figures 1 to 5. Therefore, only the existing differences between the two variants will be described below. In Figure 8, the housing part 8 and the outlet step 19 are not shown for better visibility. In Figure 9, the housing part 8 is not shown.

[0317] As can be seen from Figures 8 and 9, the separation stage 6 is also designed as a basic body with a three-dimensional structure in the form of a separation plate 6. On the outflow side 15 of the separation plate 6 facing the mixing stage 7, a plurality of air channels 16 are incorporated into the separation plate 6 as a recess open on one side. The air channels 16 are parallel to each other and to the flow obstructions 32, extending continuously from an outer circumference of the separation plate 6 to the wall 54 of the support 33 at the centerline of the outflow side.

[0318] 15 of the disassembly plate 6 are formed. The holes 27 arranged in one of the common rows 37 open into an air channel 16 formed parallel to this row 37. The holes 27 arranged in different rows 37 are thus separated by ribs formed in the disassembly stage 6 between the air channels 16.

[0319] The air channels 16 form one section of the ventilation passage 9. Air flows from the annular space described in connection with Figures 1 to 5 into the air channels 16 and is thus distributed particularly quickly and evenly across the mixing stage 7. The formation of air channels 16 on the disassembly plate 6 allows for a space-saving design of the sanitary insert, because the ventilation passage 9 is then at least partially formed within the material of the disassembly stage 6. Furthermore, the water jets emerging from the holes 27 can be directed effectively onto the flow obstructions 32 arranged in the main flow direction 25 beneath the air channels 16 and simultaneously receive excellent ventilation.

[0320] On the downstream side below the air ducts 16, the flow obstructions 32 are arranged, as in the variants shown in Figures 1 to 7. In the variant shown in Figures 8 and 9, the flow obstructions 32 are arranged in only two levels 38, 39. Furthermore, the flow obstructions 32 have a modified, namely elliptical, non-circular cross-section 30. The length ratio of the extent of the non-circular cross-section 30 in the main flow direction 25 to the extent perpendicular to this direction 25 is also at least 2 here.

[0321] Particularly due to the modified cross-section 30, the wall of the support 33 and the pressure equalization recess 36 are also designed somewhat differently. However, their function remains unchanged. In another variant, the cross-section 30 of the flow obstructions 32 can be oval. Variants are also possible in which different cross-sections 30 described here are combined. In the variant shown in Figures 8 and 9, the ring 17 of the disassembly stage connection described in connection with Figures 1 to 5 is also designed differently. The ring 17 shown in Figures 8 and 9 can be replaced by the ring shown in Figures 1 to 5, and vice versa.

[0322] Figures 10 and 11 show another alternative variant of the sanitary insert 1. This variant is similar to the variant shown in Figures 8 and 9. Therefore, only the existing differences between these two variants will be described below.

[0323] The flow obstructions 32 of the variant shown in Figures 10 and 11 are arranged in three levels 38, 39, 40. The flow obstructions 32 of the first level 38 and the third level 40 are stacked one above the other, as in the variant shown in Figures 1 to 5, and the second level 39 is laterally offset from them. The non-circular cross-section 30 of the flow obstructions 32 in the first level 38 and the second level 39 is elliptical, as in the variant shown in Figures 8 and 9. The ratio of the length of the non-circular cross-section 30 in the main flow direction 25 to the length perpendicular to this direction 25 is also at least 2 in the first level 38 and the second level 39.

[0324] In contrast, the cross-section 30 of the flow obstructions 32 on the third level 40 is round. The ratio of the length of the cross-section 30 in the main flow direction 25 to the length perpendicular to this direction 25 is therefore exactly 1 on the third level 40. Thus, the ratio of the length of the non-circular cross-section 30 in the main flow direction 25 to the length perpendicular to this direction 25 decreases across the two adjacent levels 39 and 40.

[0325] Figure 12 shows another alternative version of the sanitary insert 1. This version is also similar to the version shown in Figures 1 to 5. Therefore, only the existing differences between the two versions will be described below. For better visibility, the housing part 8 and the outlet step 19 are not shown in Figure 12.

[0326] In the variant shown in Figure 12, the orientation of the flow obstructions 32 between the two adjacent levels 39, 40 of the three levels 38, 39, 40 forms an angle of 90°. In other words, the second (i.e., middle) level 39 and the third (i.e., lower) level 40 in the main flow direction 25 are rotated relative to each other about a longitudinal axis of the sanitary inlet part 1, which is aligned parallel to the main flow direction 25. This allows for an excellent distribution of the flow cross-sections 32 relative to the flow cross-section of the mixing stage 7.

[0327] Figure 13 shows another alternative version of the sanitary insert 1. This version is also similar to the version shown in Figures 1 to 5. Therefore, only the existing differences between the two versions will be described below. For better visibility, the housing part 8 and the outlet step 19 are not shown in Figure 13.

[0328] In the variant shown in Figure 13, the arrangement 41 of flow obstructions is also designed such that the flow obstructions 32 are arranged in the three levels 38, 39, 40. At least one level 40, namely the third level 40 in the main flow direction 35, has at least two, namely three, areas 48, 49, 50 of flow obstructions 32. These areas are also shown in Figure 18, which depicts the lower

[0329] The arrangement 41 described here, consisting of flow obstructions 32, is shown in isolation. In the arrangement 41 described here and shown in Figures 13 and 18, the orientation of the flow obstructions 32 differs between two of the three regions 48, 49, 50. While the flow obstructions 32 in a first region 48 are oriented parallel to the holes 27 arranged in rows 37, the flow obstructions 32 in the second region 49 and the third region 50 are oriented transversely, in particular orthogonally, to the flow obstructions 32 of the first region 48. Furthermore, the flow obstructions 32 of the second region 49 and the third region 50 project in opposite directions from the outwardly facing longitudinal sides of the two outermost flow obstructions 32 of the first region 48.

[0330] This orientation ensures that the flow obstructions 32 of the second level 39 are aligned parallel to the flow obstructions 32 of the first area 48 of the third level, and that the flow obstructions 32 of the second level 39 form an angle of 90° with the flow obstructions 32 of the second area 49 and the third area 50 of the third level 40. In other words, the orientation of the flow obstructions 32 between the two adjacent areas forms an angle of 90°, namely between the second level 39, which is designed as a single area, and the second area 49 and the third area 50 of the third level 40. This also allows for an excellent distribution of the flow cross-sections 32 relative to the flow cross-section of the mixing stage 7.

[0331] Figures 14 and 15 are described in connection with Figure 6.

[0332] Figure 16 shows another variant of arrangement 41 of

[0333] Flow obstructions 32 in a schematic representation.

[0334] The length ratio of the cross-sectional area 30 in the first 38 and last 39 levels of the at least three levels 38, 39, 40 in the main flow direction 25 is greater than in the intermediate level 38. This allows the advantages described, achievable with the decreasing length ratio in the main flow direction 25, to be combined with the particularly good jet alignment produced by the last level 40. This arrangement 41 can be combined with the described mixing stage 7 and / or the described sanitary insert 1.

[0335] Figure 17 shows a further variant of the arrangement 41 of flow obstructions 32 in a schematic representation. In this variant, the arrangement 41 does not have the support described above. The two levels 38, 39 can be connected to each other, in particular formed in one piece, or can support each other loosely. For example, the connection or support can be achieved by means of a spacer 51, which here is designed as a ring. In the arrangement 41, the levels 38, 39 overlap analogously to the manner described in connection with Figure 4. This arrangement 41 can also be combined with the described mixing stage 7 and / or the described sanitary insert 1.

[0336] Figure 18 shows, in isolation, the lowest level 40 of the arrangement 41 of flow obstructions 32 of the variant of a sanitary insertion device 1 shown in Figure 13 and is described in connection with Figure 13. The isolated view shows that the flow obstructions 32 of the first section 48 are connected to each other by means of the support 33. The flow obstructions 32 of the second section 49 and the third section 50 project from an outer surface of the outer flow obstructions 32 of the first section 48 and are additionally supported by the upstream flow obstructions 32 of the second level 39, which are oriented transversely to the flow obstructions 32 of the second section 49 and the third section 50. This figure also shows that the two lower levels 38, 39 overlap section by section in the main flow direction 25.

[0337] Figure 19 shows a further variant of the arrangement 41 of flow obstructions 32. This variant is similar to the lowest level 40 of the arrangement 41 of flow obstructions 32 shown in Figure 18. Therefore, only the existing differences between the two variants will be described below. In contrast to the variant of the arrangement 41 of flow obstructions 32 shown in Figure 18, the arrangement 41 described here has only one level, namely level 40, which is designed similarly to the third level 40 in Figure 13, located in the main flow direction 25. Optionally, the variant described here can have further levels of the type shown here or of another type, for example, with flow obstructions 32 that are exclusively parallel to each other. The individual flow obstructions 32 of the first section 48 can be connected to each other by a holder 52.The flow obstructions 32 of the second section 49 and the third section 50 can be configured as described in connection with Figure 18. The arrangement 41 described here can be combined with the described mixing stages and / or sanitary insertion devices.

[0338] Figure 20 shows a further variant of the arrangement 41 of flow obstructions 32 with a support 33. This variant has parallel flow obstructions 32 in two tiers 38, 39. The support 33 differs from the support 33 of the variant shown in Figures 1 to 5. In the variant shown in Figure 20, the support 33 also consists of the central, round pillar 53, which is rigidly connected to the disassembly plate 6, and the thin wall 54. However, the wall 54 is not flat, as shown in Figures 1 to 5, but rather a ring that radially surrounds the arrangement 41 of flow obstructions 32. In particular, each of the tiers 38, 39 shown can have its own ring. The flow obstructions 32 are firmly connected to the wall 54, in particular formed integrally with it.

[0339] Figure 21 shows an application of the sanitary insert in an analogous view to the application shown in Figure 2. This application is similar to the application and arrangement shown in Figures 1 and 2. Therefore, only the existing differences are described below. The application shown in Figure 21 differs from the application shown in Figure 2 in that the internal thread 13 is formed directly on the outlet piece 3, so that the sanitary insert 1 can be screwed directly onto the outlet piece 3 by means of the external thread 12 formed on the housing part 8. A connecting part 2 is therefore not required.

[0340] Figures 22 to 24 show the intended use shown in Fig. 1, or the connecting part 2, in further sectional views. Figures 22 to 24 also reveal a fluidic arrangement and the use of a fluidic arrangement, in particular the fluidic arrangement.

[0341] The fluidic arrangement 82 has the connection part 2. A hose connection 55 and a receptacle 56 for the sanitary insert 1 are formed on the connection part 2. The hose connection 55 serves to connect a hose 81, which can be flexible or rigid. The receptacle 56 is designed as a chamber which serves to receive the sanitary insert 1. The receptacle 56 can be open, in particular in the intended main flow direction, so that the sanitary insert 1 can be inserted. The receptacle 56 and the hose connection 55 are in fluidic communication, so that a fluid, in particular water, can flow from the hose connection 55 into the receptacle 56. Thus, the sanitary insert 1, which is inserted into the receptacle 56, can be supplied with the fluid, in particular water.The connection part 2 has at least one air guide 57 for supplying air from outside the connection part 2 into the receptacle 56, so that a fluid, in particular water, dispensed by the fluidic arrangement can be supplied with air. In particular, it is not necessary for the sanitary insert part 1 itself to have means for supplying air in order to generate the aerated jet. Once the air has flowed through the air guide 57 into the receptacle 56, the air is available for mixing with a fluid to be dispensed by the sanitary insert part 1. For mixing, the air can flow through the described aeration passage 9 into the mixing stage 7.

[0342] The air conduits 57 have several openings 63 in a wall 64 of a sleeve-shaped section of the connection part 2, through which the air can be supplied to the sanitary insert part 1 via connection part 2.

[0343] In the variant shown here, the air conduits 57 are configured to draw air from an interior space 58 of the sanitary fitting 59, which accommodates the hose connection 55. The sanitary fitting 59 is, in particular, the sanitary fitting of the outlet piece 3. Due to this design, an opening for supplying air on the downstream side of the fluidic arrangement is advantageously not required. In particular, no opening for supplying air is required at the sanitary insert 1 arranged in the receptacle 56. In this way, a visually appealing sanitary fitting can be designed.

[0344] In variants of the fluidic arrangement, the air conduits 57 are designed to draw in air from the outlet opening 11 of the sanitary fitting 59 (not shown).

[0345] As can be seen in particular in Figure 24, the air conductors 57 are at least partially also formed on an inner surface 61 limiting the receptacle 56 in a threaded area 62, namely on the internal thread 13.

[0346] The figures also show in particular the use of the connection part of the fluidic arrangement for supplying air from outside the connection part 2 to the sanitary insert part 1 which is inserted into a receptacle 56 of the fluidic arrangement.

[0347] Figure 25 shows yet another alternative variant of the sanitary insert 1, whereby one housing part of the sanitary insert is omitted for clarity. This variant is also similar to the variant shown in Figures 1 to 5. Therefore, only the existing differences between the two variants will be described below.

[0348] In the variant shown in Figure 25, the support 33 is not formed integrally with the separation stage 6, nor with the outlet stage 19, which is designed as an outlet structure 20. Rather, the support 33 is rigidly connected to the separation stage 6 on the upstream side and to the outlet stage 19, which is designed as an outlet structure 20, on the downstream side by means of the pier 53. For this purpose, an upstream section of the pier 53 engages an undercut in a recess of the separation stage. This results in a variant of the described support connection, which can have the interface 44 for aligning the flow obstruction 32 relative to the separation stage 6. Furthermore, a downstream section of the pier 53 engages an undercut in a recess of the outlet stage 19, which is designed as an outlet structure 20.This connection can also have an interface that can align the flow obstructions and the outlet stage relative to each other around a longitudinal axis that is aligned parallel to the main flow direction.

[0349] Alternatively, in variants of the insert where the support 33 of the mixing stage 7 is not integrally formed with the separation stage 6, as shown, for example, in the variant of the insert 1 depicted in Figure 25, the orientation of the flow obstructions 32 relative to the separation stage 6 is randomized with respect to rotations about the longitudinal axis, which is aligned parallel to the main flow direction 25. In this case, the interfaces determining the defined orientation can be omitted, particularly if a sufficient number of holes are included in the separation stage 6. This variant can be advantageous, for example, when high flow classes are implemented.

[0350] Figure 26 shows yet another alternative variant of sanitary fitting 1. This variant is also similar to the variant shown in Figures 1 to 5. Therefore, the existing differences between the two variants will be described below.

[0351] The variant shown in Figure 26 and the variant shown in particular in Figure 4 differ in that, in the variant shown in Figure 26, the ventilation passage 9 is not formed by means of the ventilation openings 24. The ventilation openings 24 are therefore omitted in the variant shown in Figure 26. Instead, the mixing stage 7 of the variant shown in Figure 26 has a sleeve 73. The sleeve 73 can be placed on the arrangement 41 of flow obstructions 32 and inserted into the housing part 8, so that the sleeve 73 surrounds the flow obstructions 32 laterally and is enclosed on the outside by the housing part 8. In the inserted state, the sleeve 73 has a lateral gap to the housing part 8.

[0352] The sleeve 73 is supported by the arrangement 41 of flow obstructions 32 and by the outlet stage 19, which is designed in particular as an outlet structure 20. For this purpose, an inner contour of the sleeve 73 is connected to an outer contour of the arrangement 41 of flow obstructions 32 by means of a press fit, and the sleeve 73 rests on the outlet structure 20.

[0353] The sleeve 73 can be variably attached or inserted and, if necessary, removed again to influence the flow in the mixing stage 7. When the sleeve 73 is inserted, water can, for example, be guided through an interior enclosed by the sleeve 73. This reduces the flow cross-section of the water jet that can be dispensed with the sanitary insert 1. Additionally, the ventilation channel 9 leading into the mixing stage 7 can be routed between the inner surface 60 of the housing part 8 and an outer surface 75 of the sleeve 73. The air guided past the sleeve 73 can, for example, be directed past an inflow-side end of the sleeve 73 into the interior enclosed by the sleeve 73 and mixed there with the water. Alternatively, the sleeve can also provide a ventilation opening of the type described, so that a section of the ventilation channel 9 passes through the sleeve 73.

[0354] By means of the sleeve 73, a ventilation passage 9 can therefore be formed flexibly and easily in a sanitary insertion unit 1, which otherwise does not provide any means for ventilating the water jet.

[0355] The sleeve 73 may have openings or recesses at its upstream end, i.e. near or at the bursting stage 6, to supply supplied air to the bursting nozzles 27.

[0356] Figures 27 and 28 show yet another alternative variant of the sanitary insert 1 from different perspectives. This variant is similar to the one shown in Figure 7. Therefore, only the existing differences between the two variants will be described below.

[0357] Unlike the variant of the sanitary insert 1 shown in Figure 7, the variant shown in Figures 27 and 28 has a housing part 8 with a double wall 70. The double wall 70 has an outer wall 71 and an inner wall 72 formed integrally with it. The outer wall 71 and the inner wall 72 are arranged coaxially and spaced apart from each other. The integral formation of the outer wall 71 and the inner wall 72 is achieved by means of spaced-apart structures 78 oriented parallel to the longitudinal direction, so that a space is formed between the outer wall 71 and the inner wall 72.

[0358] The housing part 8 is connected to the disassembly stage 6 by means of a disassembly stage connection. The disassembly stage 6 is connected to the support 33 by means of a support connection. The support connection has a symmetry-breaking interface that allows the support 33 to be connected only in a way in which a defined orientation of the flow obstructions 32 relative to the disassembly stage 6, in particular relative to an arrangement of the holes 27, is achieved. For this purpose, a recess 76, in particular rectangular, is formed on the downstream side 15 of the disassembly stage 6, into which a corresponding, in particular complementary, counter-geometry 77 of the support 33 engages.

[0359] The inner wall 72 has, as in the variant shown in Figure 7, a round inner surface 60.

[0360] On a downstream section 65, the outlet stage 19, designed as an outlet structure 20, can be connected to the housing part 8 via an outlet stage connection of the type described. This allows the outlet stage 19 to be supported by the housing part 8.

[0361] The outlet step connection is designed as a positive-locking connection in the variant shown in Figures 27 and 28. For this purpose, a circumferential recess, semicircular in shape in the longitudinal section of the insert, is formed in the inner wall 72 of the downstream section 65. The outer contour 21 of the outlet step 19 is designed to correspond to this recess and engages in it. The outlet step 19 can, for example, be inserted into the housing 8 on the upstream side in the main flow direction 25, so that the outlet step connection is captive when the insert 1 is used as intended. Alternatively, the outlet stage 19 can be inserted into the housing 8 on the outflow side against the main flow direction 25 by elastically pressing the outflow-side section 65 of the inner wall 72 radially outwards and allowing it to spring back when the outlet stage 19 is positioned as intended.

[0362] Due to the described free space between the outer wall 71 and the inner wall 72, water can be guided through an interior space enclosed by the inner wall 72. This reduces the flow cross-section of the water jet dispensed by the sanitary insert 1 compared to a variant of the insert 1 that has the same core diameter of the fastening element, for example, designed as an external thread 12, but lacks an inner wall 72. Additionally, the ventilation passage 9 leading to the mixing stage 7 can be routed between the outer wall 71 and the inner wall 72. The air passing by the inner wall 72 can, for example, be directed past an inflow-side end of the inner wall 72 into the interior space enclosed by the inner wall 72 and mixed there with the water.For this purpose, the inner wall at an inflow-side end, where the inner wall 72 of the housing 8 abuts the separation stage 6, can have a crown, i.e., an uneven end face. Air can thus flow between the crown and the outlet stage 6 through ventilation openings.

[0363] Figures 29 and 30 show yet another alternative variant of the sanitary insert 1. Figure 29 shows the insert 1 in an assembled state. Figure 30 shows an exploded view to illustrate details of the disassembly stage 6, the housing part 8, and the mixing stage 7 with the outlet stage 19. This variant is similar to the one shown in Figures 27 and 28. The differences between the two variants are therefore described below.

[0364] The variant shown in Figures 29 and 30 also features the double wall and the integrally formed outer wall 71 and inner wall 72. The sectional view in Figure 29 shows that the integral formation of the outer wall 71 and the inner wall 72 is achieved by means of the spaced-apart structures 78, which are aligned parallel to the longitudinal direction.

[0365] Unlike the variant shown in Figures 27 and 28, the inner surface 60 of the inner wall 72 is not round, but non-circular. In the variant shown here, the inner surface forms the inner contour of a regular octagon. However, other inner contours are also conceivable, for example, that of a triangle, a quadrilateral, a pentagon, a hexagon, an ellipse, or an oval. As a result, the inner surface 60 surrounds a non-circular flow cross-section, particularly around the mixing stage 7 and the outlet stage 19.

[0366] The support connection also does not have the symmetry-breaking interface shown in Figures 27 and 28. The support connection shown in Figures 29 and 30 has a rotationally symmetrical interface, which would allow rotation of the support 33. However, this rotation is prevented by the non-circular inner surface 61 of the inner wall 72 and the corresponding outer contour of the arrangement 41 of flow obstructions 32.

[0367] The alignment of the flow obstructions 32 relative to the disassembly stage 6 can be achieved by the disassembly connection having a symmetry-breaking interface 68. For this purpose, a plurality of fixing elements 79 are formed on the outside of the outflow side 15 of the disassembly stage 6. A crown is formed on the inner wall 72, with projections extending against the flow direction serving as the described retaining projections 18 on which the disassembly stage 6 rests. In the assembled position, ventilation openings 24 are thus formed between the disassembly stage 6 and the inner wall 72. The connection of the disassembly stage 6 and the housing part 8 described here is only possible in one predetermined orientation. For this purpose, one or more of the fixing elements 79 and the corresponding projection can deviate geometrically from the other fixing elements 79 and projections.

[0368] Furthermore, the outlet stage connection also has a symmetry-breaking interface 69. This interface 69 is formed by an asymmetrical outer contour of the outlet stage 19 and a corresponding inner contour of a downstream section 65 of the inner wall 72. The outer contour of the outlet stage 19 is formed by outwardly projecting grid elements, one of which is slightly longer than the others. In the assembled state, the longer grid element engages in an engagement recess 80 shown in Figure 30 on a downstream section 65 in the inner wall 72. This engagement allows for a predetermined orientation of the outlet stage 19 relative to the housing part 8.

[0369] Due to the interface 69 outlet stage connection and the interface 68 of the disassembly stage connection, the outlet stage 19 and the fixed, in particular integral, arrangement 41 of flow obstructions 32 connected thereto can be arranged in a defined orientation relative to the disassembly stage 6, in particular relative to an arrangement of the holes 27.

[0370] Figures 31 and 32 show yet another alternative variant of the sanitary insert 1. Figure 31 shows the insert 1 in an assembled state. Figure 32 again shows an exploded view to illustrate details of the disassembly stage 6, the housing part 8, and the mixing stage 7 with the outlet stage 19. This variant is similar to the one shown in Figures 29 and 30. The differences between the two variants are therefore described below.

[0371] The variant shown in Figures 31 and 32 also features the double wall 70. However, the inner wall 72 has a plurality of grip recesses 80. The outlet stage 19 also has a plurality of outwardly projecting grid elements corresponding to the grip recesses 80. One of these combinations of grip recess 80 and corresponding grid element is geometrically different from the other combinations, so that a symmetry-breaking interface 69 is formed. This allows for a defined alignment of the outlet stage 19 and the flow obstructions 32, which are rigidly connected to it, particularly those formed in one piece, relative to the housing part 8.Due to the separation stage connection described in connection with Figures 29 and 30, a defined alignment of the outlet stage 19 and the flow obstructions 32 firmly connected thereto, in particular formed in one piece, relative to the separation stage 6, in particular relative to an arrangement of the holes 27, can be achieved.

[0372] Simultaneously, the engagement recesses 80 and the corresponding projecting grid elements can establish the discharge stage connection. The discharge stage 19 can thus, for example, be held securely in the housing part 8. In this respect, it is possible to dispense with the support connection between the support 33 and the disassembly stage 6 described in the other variants for supporting the support, as can be seen particularly in Figure 31. In this case, the discharge stage 19 and the mixing stage 7 are supported exclusively by the housing part 8.

[0373] The arrangement 41 of flow obstructions 32, described in connection with Figures 1 to 32 and projecting from a support 33, is ideally suited for use in forming a mixing stage 7 of a sanitary insert 1, in which the support 33 is rigidly connected, in particular integrally, to the outlet stage 19, which is in particular round. In this application, the support 33 with the flow obstructions 32 and the outlet stage 19 can be arranged, in particular, on the downstream side of the separating stage 6.

[0374] As shown by figures 1 to 32 and the associated

[0375] The description shows a method for forming a sanitary insert 1, wherein the method comprises the following steps:

[0376] - Providing a disassembly stage 6 and an arrangement 41 of flow obstructions 32, which project from a support 33 which is firmly connected, in particular in one piece, with a particularly round outlet stage 19;

[0377] - Merging of the carrier 33 and the disassembly stage 6, in particular against the intended main flow direction 25;

[0378] - Connecting the support 33 to the disassembly stage 6 such that the support 33 and the flow obstructions 32 are arranged downstream of the disassembly stage 6 and that the flow obstructions 32 are located transversely to the main flow direction 25.

[0379] As can also be seen from Figures 1 to 24 and the associated description, another method for forming a sanitary insert 1 is described, the method comprising the following steps:

[0380] - Providing a housing part 8 and a disassembly stage 6, wherein the disassembly stage 6 is firmly connected, in particular integrally, to a support 33 and the support 33 is firmly connected, in particular integrally, to a discharge stage 19, in particular round, wherein an arrangement 41 of flow obstructions 32 projects from the support 33;

[0381] - Merging of the housing part 8 and the disassembly stage 6, in particular against the intended main flow direction 25;

[0382] - Connecting the disassembly stage 6 to the housing part 8 such that the support 33 and the flow obstructions 32 are arranged downstream of the disassembly stage 6 in the housing part 8 and that the flow obstructions 32 are located transversely to the main flow direction 25.

[0383] Furthermore, it can be seen from Figures 1 to 24 and the associated description that a method for introducing an arrangement 41 of flow obstructions 32 into a sanitary fitting is described, wherein the flow obstructions

[0384] 32 of a carrier firmly connected, in particular in one piece, with a particularly round outlet step 19 formed

[0385] 33, and the procedure comprises the following steps:

[0386] - Insertion of the arrangement 41 of flow obstructions 32 into the sanitary fitting through the outlet opening 11 of the sanitary fitting;

[0387] - Fixing the arrangement 41 in the sanitary fitting .

[0388] In the method for introducing the arrangement 41 of flow obstructions 32 into the sanitary fitting, the following additional steps may be provided, in particular as part of a method for introducing a sanitary insert 1 into the sanitary fitting:

[0389] - Insertion of a disassembly stage 6 into the sanitary fitting, in particular through the outlet opening 11 of the sanitary fitting;

[0390] - Fixing disassembly stage 6;

[0391] - Connecting the support 33 to the separating stage 6 in the sanitary fitting such that the support 33 and the flow obstructions 32 are arranged downstream of the separating stage 6 and that the flow obstructions 32 are located transversely to the main flow direction 25.

[0392] Alternatively, in the method for introducing the arrangement 41 of flow obstructions 32 into the sanitary fitting, in particular as part of a method for introducing a sanitary insert 1 into the

[0393] Sanitary fitting, the following additional steps are provided, wherein the support 33 is firmly connected, in particular in one piece, with a disassembly stage 6, in particular round:

[0394] - Inserting the disassembly stage 6 with the arrangement 41 and the outlet stage 19 into the sanitary fitting, in particular through the outlet opening 11 of the sanitary fitting;

[0395] - Fixing the disassembly stage 6 such that the support 33 and the flow obstructions 32 are arranged downstream of the disassembly stage 6, in particular in the housing part 8, and that the flow obstructions 32 are located transversely to the main flow direction 25.

[0396] Based on the description of the variants, a series of sanitary insert parts 1 with at least two variants of sanitary insert parts 1 is also described, wherein both variants each have a matching disassembly stage 6, the disassembly stage 6 of both variants being connectable to a support 33 arranged downstream of the disassembly stage 6, as shown, for example, in Figures 6, 14, or 15. The support 33 is rigidly connected, in particular integrally, to a downstream, in particular round, outlet stage 19. The first variant has a first arrangement 41 of flow obstructions 32 lying transversely to a main flow direction 25 and projecting from the support 33, and the second variant has a second arrangement 41 of flow obstructions 32 lying transversely to a main flow direction 25 and projecting from the support 33, which differs from the first.In this context, it is also explicitly pointed out that the variants of the arrangement 41 of the flow obstructions 32 shown in Figures 8 to 24 can be formed on a support 33 that can be connected to the disassembly stage 6. Figure 33 shows a ventilated variant of Figure 31. Functionally and / or structurally similar or identical components and functional units are designated with the same reference numerals and are not described separately again. The explanations relating to the previous figures therefore apply accordingly.

[0397] In the embodiment according to Fig. 33, a ventilation passage 9 leading into the mixing stage 7 is designed as an air guide 57, wherein the ventilation passage 9 runs through the housing part 8 which laterally encloses the mixing stage 7 and passes through an octagonal sleeve 73 which is integrally formed on the housing part 8 to form a double wall.

[0398] Based on the description of the variants, a further series of sanitary insert parts 1 with at least two variants of sanitary insert parts 1 is also described, wherein both variants each have a matching housing part 8, the housing part 8 of both variants being connectable to a disassembly stage 6 that can be arranged in the housing part 8. The disassembly stage 6 is rigidly connected, in particular integrally, to a downstream-arranged support 33, and the support 33 is rigidly connected, in particular integrally, to a downstream-arranged, in particular round, outlet stage 19. The first variant has a first arrangement 41 of flow obstructions 32 lying transversely to a main flow direction 25 and projecting from the support 33; the second variant has a second arrangement 41 of flow obstructions 32 lying transversely to a main flow direction 25 and projecting from the support 33, which differs from the first.In this context, it is explicitly pointed out once again that the variants of the arrangement 41 of the flow obstructions 32 shown in Figures 8 to 24 can be formed on a disassembly stage 6, which, like the disassembly stage 6 shown in Figures 1 to 5, can be connected to the housing part 8.

[0399] Fig. 34 shows a further embodiment of the invention. Components and functional units that are functionally and / or structurally similar or identical to the preceding embodiments are designated with the same reference numerals and are not described separately again. The descriptions relating to Figures 1 to 33 therefore apply accordingly to Figure 34.

[0400] A sanitary fitting 59 has an interior 58, preferably as part of a spout pipe, in which a hose 81, which may be flexible or rigid, is arranged in a fluidic arrangement 82. The hose 81 may, for example, be fluidically connected to a valve, such as a valve cartridge or an angle valve, or preferably an electrically controlled valve.

[0401] The fluidic arrangement 82 has a hose connection 55 to which the hose 81 is connected or molded. The hose connection 55 is formed on a connection part 2.

[0402] The connection part 2 has a receptacle 56 in which a sanitary insert 1, for example as described above, is inserted or formed. The sanitary insert 1 can, for example, be or form a vented aerator. For this purpose, the sanitary insert 1 has at least one vent opening 24. The hose connection 55 is fluidically connected to the receptacle 56.

[0403] Air conduits 57 are formed on the connection part 2 to supply air from the outside, for example from the interior 58 or from outside the sanitary fitting 59, to the sanitary insert 1. The air conduits 57 can, for example, be formed as an open or closed channel on or in a wall 64 of the connection part 2, or may have such a channel.

[0404] For example, the air conductors 57 can be formed as a penetration 63 through the wall 64 (variant 57.1) and / or on an inside of the wall 64 (variant 57.2) and / or in the wall 64 (variant 57.3) and / or on an outside of the wall 64 (variant 57.4).

[0405] The ventilation opening 24 of the sanitary insert part 1 is in fluidic communication with the air conductor 57 or the air conductors 57 of the connection part 2 .

[0406] In the figure 56, a sealing element 29 fluidically separates the hose connection ( 55 ) from the at least one air conductor 57.

[0407] The sealing element 29 can, for example, be designed as a separate sealing ring.

[0408] The sealing element 29 can, for example, be molded onto the connection part 2 and / or the sanitary insert part 1.

[0409] The sealing element 29 makes contact with the sanitary insert part 1 on the one hand and the connection part 2 on the other hand, sealing .

[0410] Fig. 34 thus shows (similar to Figs. 22 to 24) a general use of a connection part 2 of a fluidic arrangement 82, in particular as previously described and / or claimed below, for supplying air from outside the connection part 2 to a sanitary insert 1 inserted into a receptacle 56 of the fluidic arrangement 82, in particular via an interior 58 of a sanitary fitting 59 accommodating the fluidic arrangement 82 and / or via an outlet opening 11 of, for example, the aforementioned sanitary fitting 59 and / or between the sanitary
