Description

[0001] 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.

[0002] The invention relates to 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 transverse to a main flow direction.

[0003] The invention also relates to the use of an arrangement of flow obstructions projecting from a support to form a mixing stage of a sanitary insert.

[0004] Furthermore, the invention relates to methods for forming a sanitary insert, a method for introducing an arrangement of flow obstructions into a sanitary fitting, and methods for introducing a sanitary insert into a sanitary fitting.

[0005] Furthermore, the invention relates to series of sanitary insert parts with at least two variants of sanitary insert parts.

[0006] 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.

[0007] The invention also relates to the use of a connecting part of a fluidic arrangement for supplying air from outside the connecting part to a sanitary insert part inserted into 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 the flow rate. For instance, it can be a throttle that reduces the flow rate by a factor dependent on the pressure difference within a given operating range. Alternatively, the reducing stage can be a flow regulator that reduces the flow rate to a value that is practically or precisely independent of the pressure within a given operating range. Flow regulators often feature an elastic control element that deforms under operating pressure and changes the area of ​​a flow orifice depending on the pressure.

[0011] One possible function that can be achieved 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 this 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 a discharge structure, for example, can perform rectifying functions, such as generating a unidirectional flow. Another function of an outlet stage can be to form a fluidically permeable seal for 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.

[0016] To solve the aforementioned problem, the invention proposes the subject matter of the independent claims.

[0017] 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.

[0018] 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.

[0019] A rigid connection between the support and the run-out 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 run-out step. A particularly rigid connection between the support and the run-out step can be achieved by forming these two components as a single piece.

[0020] Due to the firmly connected, in particular one-piece, design of the support with the outlet step, the support with the flow obstructions and the outlet step can be easily arranged together in an outlet piece of a sanitary fitting.

[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 opposite 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, the outlet step can be designed as a circular discharge structure. A circular outlet step, when used as intended, has a round, particularly circular, outer circumference perpendicular to the main flow direction. For example, the outer circumference of the discharge structure can be round.

[0024] If the outlet step is round and firmly connected to the support, especially in one piece, the round outlet step can be easily used and thus a round jet, which is popular in practice, can be quickly made available and / or adapted.

[0025] 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, for a sanitary insert with a separation stage and a mixing stage located 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 on the support in at least two levels. It is advantageous that good mixing in the manner of a cascade can be achieved when a fluid, in particular water, flows through the sanitary insert as intended.

[0026] 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.

[0027] 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 enables a compact design of the sanitary fitting.

[0028] 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.

[0029] 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.

[0030] The flow obstructions of a second of the two adjacent levels can, in particular, be arranged laterally offset from the flow obstructions of a first of the two adjacent levels. Specifically, 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.

[0031] 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.

[0032] 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, for 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 protrude from the support.

[0033] 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.

[0034] 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.

[0035] By creating zones on at least one level, especially in combination with at least one further level of flow obstructions, the flow obstructions can be particularly well distributed within a flow cross-section of the mixing stage. This allows for particularly effective mixing of the flow within the mixing stage, especially without the flow being able to penetrate deep into the mixing stage unimpeded.

[0036] 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.

[0037] 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 step.

[0038] 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.

[0039] In particular, if the sanitary installation unit has at least two floors and at least one of these floors has two sections, it may additionally or alternatively be provided that the orientation of the flow obstructions, especially the orientation of the flow obstructions described here, forms an angle between two sections of the at least two floors. In other words, the flow obstructions of a section of a first of the two floors may be rotated relative to the flow obstructions of a section of a second of the two floors with respect to a longitudinal axis. In particular, the orientation of the flow obstructions of two adjacent sections may form an angle. Additionally or alternatively, the angle may be 90°, so that the flow obstructions in the two sections may be rotated orthogonally to each other.

[0040] 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.

[0041] Alternatively, in practice, the support can be connected to the disassembly stage via a connection. This connection can be force-fit and / or form-fit. In particular, the connection can be captive, for example, by locking or snapping. If required, the support can also be detachably connected to the disassembly stage.

[0042] 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 connection, the aforementioned combination can be modified subsequently, allowing for adaptation to changing requirements while minimizing waste. With a permanent connection, the advantage is that it prevents the unwanted loosening or subsequent replacement of components within the combination.

[0043] The connection can have a symmetry-breaking interface, in particular where the interface defines an orientation of the flow obstructions relative to the disassembly stage with respect to rotations about a longitudinal axis. This makes it easy to align the flow obstructions to a pattern or arrangement of holes in the disassembly stage without requiring subsequent verification or increased assembly effort. It is thus easily achieved that the disassembly nozzles and flow obstructions automatically align themselves, or that the disassembly nozzles and flow obstructions are precisely aligned with each other.

[0044] In particular, the separation stage, designed, for example, as a separation 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 separation stage. Additionally or alternatively, if the separation stage is intended to be arranged in a sanitary fitting, the recess can be engaged and / or penetrated 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 separation 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 also allows the projection of the carrier to be easily inserted into the recess.

[0045] A cross-section of the projection and a cross-section of the corresponding recess can be rotationally asymmetrical in order to form the symmetry-breaking interface.

[0046] The projection and / or recess may additionally or alternatively feature retaining elements, such as locking lugs. These locking lugs can engage behind a shoulder, thus enabling a secure plug-in connection between the disassembly stage and the support with the flow obstructions.

[0047] In practice, it may be further stipulated that the outlet step is supported by the disassembly step. This support can be achieved, for example, by forming the outlet step integrally with the disassembly step via the support. Alternatively, the support can be achieved by connecting the outlet step to the disassembly step via the support. Apart from this, the outlet step may otherwise be unattached. 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, the outlet step can have a free, i.e., .The outer circumferential edge is not fixed to any other component. Therefore, the geometry of the outlet step can be flexibly designed, particularly at the circumferential edge. In other words, the outer contour of the outlet step can be formed independently of any inner contour of a housing surrounding the outlet step and / or of any inner contour of an element surrounding the sanitary fitting, such as a mouthpiece.

[0048] Additionally or alternatively, in practice, the flow obstructions can be forcibly aligned with the positions of the holes in the separating stage for the 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 the 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 features on inserts, are unnecessary.This can also facilitate largely automated manufacturing.

[0049] Particularly when the support can be connected to the disassembly stage, the connection for achieving forced alignment can be designed 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. Specifically, 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.

[0050] As mentioned, the separation stage can be designed as a separation plate. The resulting flat arrangement of holes makes it particularly easy to align with flow obstructions.

[0051] Furthermore, it can be advantageous if the arrangement of the holes in the separation stage coincides with the shape of a flow obstruction in the main flow direction. This allows the holes to be easily covered by subsequent flow obstructions.

[0052] 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 so 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.

[0053] The aforementioned holes can each be configured as an outlet for the fragmentation nozzles of the fragmentation stage. This allows for easy predefining of the outflow directions of the individual jets, making alignment even more feasible.

[0054] 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 impinges upon 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, particularly 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.

[0055] Additionally or alternatively, it can be provided that for each hole of the disassembly stage a flow obstruction, in particular in an uppermost level, is oriented in such a way that the water exiting the hole preferably hits the flow obstruction in the middle.

[0056] In practice, the mixing stage can also be laterally enclosed by a sleeve-shaped housing part. This can be the case, for example, along the entire length between the separation stage and the discharge stage, particularly a discharge structure. Thus, for instance, an interior space of the mixing stage—specifically, a space or system of spaces accommodating flow obstructions—can be closed or delimited upstream by the separation stage, downstream by the round discharge stage, and laterally by the sleeve-shaped housing part. This allows for a compact or at least enclosed insert.

[0057] The sleeve-shaped housing part can be geometrically matched to the round outlet stage, in particular such that one, and especially the outer contour of the outlet stage described here, abuts one, and especially the inner contour of the housing part described here. The geometric matching can additionally or alternatively be designed such that the circumferential gap between the outlet stage and the housing part remains essentially constant. Thus, the support with the flow obstructions and the outlet stage can be inserted into the housing part particularly easily and / or with a precise fit, and a defined jet can be emitted.

[0058] Additionally or alternatively, the disassembly stage can be enclosed laterally by the housing part.

[0059] In practice, the housing part can be preferably permanently connected to the disassembly step via a disassembly step connection. The disassembly step connection can be force-fit and / or form-fit. In particular, the preferably permanent disassembly step connection can be captive. The permanent connection to the disassembly step connection can, in particular, be detachable only by destructive means. If required, it can also be provided that the disassembly step can be detachably connected to the housing part.

[0060] 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 a non-disconnecting step connection, it is advantageous that a particularly undesirable loosening or subsequent replacement of components of the combination can be prevented.

[0061] 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, as the separation stage is moved past the at least one retaining projection, it can be elastically deformed, at least in sections, and spring back elastically to its original shape on the inflow 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 that rises inwards in the insertion direction. The disassembly stage can have an elastic ring, particularly a circumferential one. Specifically, a retaining projection can be formed circumferentially on the inside of the housing part. Due to the circumferential ring and / or the circumferential retaining projection, a particularly secure connection between the disassembly stage and the housing part can be achieved.

[0062] 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.

[0063] As an alternative to the jointable design of the housing part with the disassembly stage, the housing part can, in practice, be formed as a single piece 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 mouthpiece.

[0064] If the housing part is formed integrally with the separating stage, and the separating stage is also formed integrally with the support, it is possible to easily arrange the separating stage, the housing part, the support with the flow restrictors, and the outlet stage together in a single outlet piece 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.

[0065] 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 a spout of a sanitary fitting and then to connect the support with the flow obstructions and the spout stage together with the disassembly stage and arrange it in the sanitary fitting.

[0066] The housing component can have a preferably circumferential retaining projection on its outer surface, which can be gripped with a connecting part and / or a nozzle. Alternatively or additionally, the housing component can have a thread on its outer surface, allowing it to be screwed into a sanitary fitting. The housing component can, for example, be made of plastic. The housing component can, for example, separate the mixing stage from an air intake chamber through which air can be supplied.

[0067] 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 one ventilation passage leading into the mixing stage is formed. Thus, air can be supplied to the mixing stage to generate an aerated jet. The ventilation passage can be formed, in particular, if the sanitary insert has a housing part, especially the housing part described above, that laterally encloses the mixing stage. The ventilation passage can, in particular, extend through the housing part and / or past an edge of the housing part.

[0068] The ventilation duct can open to the outside via an air inlet, particularly into the environment surrounding the sanitary fitting. This allows for the simple introduction of outside air into the mixing stage.

[0069] In practice, the ventilation passage may be designed to include at least one ventilation opening, at least in sections. This at least one ventilation opening may be located, in particular, in the housing part.

[0070] This allows air to be supplied directly to the mixing stage. The at least one ventilation opening can extend in a circumferential direction of the sanitary insert, so that the air is distributed along this circumference and can be supplied directly to the mixing stage. Additionally or alternatively, multiple ventilation openings can be provided in the housing. This allows the direct supply of air to be further distributed and thus improved.

[0071] If the sanitary fitting has a ventilation opening, in practice it can be provided 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 particularly effective mixing of an incoming fluid, especially water, with air flowing in through the at least one ventilation opening, without the fluid, especially water, unintentionally escaping through the ventilation openings.

[0072] In particular, the positioning of the ventilation opening can fulfill at least one of the following criteria: The distance between the ventilation opening (24) and the upstream first level (38) is at least 0.3 mm, preferably at least 0.5 mm; the distance between the ventilation opening (24) and the upstream first level (38) corresponds to at least one quarter of the distance from the separation stage (6) to this level (38); the distance between an downstream end of the ventilation opening (24) and the separation stage (6) corresponds to at least a distance from a hole (27) of the separation stage (6) located transversely, in particular orthogonally, to the main flow direction (25) to an edge of the separation stage (6).Depending on the size of the sanitary fitting and the specific circumstances of use, the aforementioned criteria can ensure that the fluid, especially 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, especially 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, especially the water pressure, is low.

[0073] The ventilation passage can additionally, or alternatively at least partially, be formed 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.

[0074] 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.

[0075] The ventilation passage can then be additionally or alternatively formed, at least in sections, by at least one air duct.

[0076] It has been shown that the formation of an air duct at the dismantling stage allows for a space-saving design of the sanitary insert, because then the ventilation passage can be formed at least partially in the material of the dismantling stage.

[0077] 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 defining ribs. Preferably, the air channel is open at one end.

[0078] 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.

[0079] Due to the arrangement of the holes in the air duct(s), water jets emerging from the holes can be directed effectively onto the flow obstructions arranged below the recesses in the intended main flow direction, while simultaneously providing excellent ventilation. Particularly good ventilation 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.

[0080] 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.

[0081] 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.

[0082] 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 no means for ventilation are provided in a sanitary insert of the type described at the outset or in a sanitary insert of the type described above. 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.

[0083] In practice, it may be provided that the mixing stage has at least two sub-chambers separated by the support, the support having at least one pressure equalization recess fluidically connecting the at least two sub-chambers.

[0084] The support can be arranged in a plane with the described centerline of the downstream side of the separation stage. The two sub-chambers can thus be essentially the same size and preferably symmetrical.

[0085] 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.

[0086] 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.

[0087] 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.

[0088] For example, this can be achieved by designing the pressure equalization recess as several pressure equalization openings that are not interconnected.

[0089] Each of the pressure equalization openings can then, for example, define a separate fluid path for equalizing pressure 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. This allows for a substantial contribution to mixing across the separation of the two sub-chambers. This effect can be particularly beneficial if at least 30% or even at least 40% of the surface area of ​​the longitudinal section is occupied. It is especially advantageous 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.

[0090] The at least one pressure equalization recess can, in particular, allow for a cross-flow with respect to the main flow direction. The formation of a cross-flow has a balancing effect between the sub-chambers, which can result in a more uniform cross-sectional pattern of the emerging water jet.

[0091] 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.

[0092] 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 can be ideally aligned 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.

[0093] 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 design can be particularly advantageous because it allows the beam and / or the 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.

[0094] 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 flow through the mixing stage can be achieved.

[0095] 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.

[0096] 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.

[0097] 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 minimizing lateral splashing of the fluid, especially water.

[0098] Additionally or alternatively, particularly in a first of at least two floors on the upstream side, and further, particularly in the first of the at least two floors described here on the upstream side, 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. , The length ratio is 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, thus facilitating the flow around the obstructions. This allows the incoming fluid to be mixed in a controlled manner.

[0099] 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 particular of the one described here, in the main flow direction to the extent perpendicular to this direction decreases over two adjacent levels.

[0100] Alternatively, it is also possible that the length ratio of the extent of a non-circular cross-section, in particular the one described here, in the main flow direction to the extent perpendicular to this main flow direction increases over two adjacent floors.

[0101] Due to the decrease and increase in length, it is possible to achieve a sanitary inlet 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, particularly water, being introduced as intended, taking place in each of these zones. Specifically, the length ratio can decrease or increase continuously across the levels, 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 because it allows for a gradually increasing mixing along the main flow direction.

[0102] 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 the particularly good jet alignment produced by the last level.

[0103] In practice, it can additionally or alternatively be provided that the non-circular cross-section becomes wider or narrower across two floors adjacent in the main flow direction of at least two floors. This makes it particularly easy to achieve the described changes in length ratios.

[0104] To solve the aforementioned problem, the features of the further dependent claim, which relates to the use of an arrangement of flow obstructions for forming 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 fitting can be formed. The discharge stage can, in particular, be round, so that a round jet, which is popular in practice, can be easily generated.

[0105] In particular, if the support and the disassembly stage can be connected, the support with the flow obstructions and the discharge stage can be arranged downstream of a disassembly stage when used.

[0106] Alternatively, especially if the support and the disassembly stage are formed in one piece, the support with the flow obstructions and the discharge stage can be arranged downstream of a disassembly stage when used.

[0107] 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.

[0108] Due to its use, 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.

[0109] 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 insert. The features and associated advantages described therein can be transferred analogously to the use as features and associated advantages.

[0110] 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: Providing a breakup stage and an arrangement of flow obstructions projecting from a beam rigidly connected to a discharge stage; joining the beam and the breakup stage; connecting the beam to the breakup stage such that the beam and the flow obstructions are arranged downstream of the breakup stage and that the flow obstructions are perpendicular to the main flow direction.

[0111] This makes it possible to flexibly and / or easily design a sanitary insert with different variations of separation stages and different combinations of support, flow obstructions, and outlet stage. A further advantage is that the support with the flow obstructions can be manufactured separately from the separation stage.

[0112] 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.

[0113] The outlet step can be round, in particular.

[0114] 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.

[0115] 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 insert. The features and associated advantages described therein can be transferred analogously to the methods as method features and associated advantages.

[0116] 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: Providing a housing part and a separation stage, wherein the separation stage is rigidly connected to a support and the support is rigidly connected to an outlet stage, wherein an arrangement of flow obstructions projects from the support; joining the housing part and the separation stage; connecting the separation stage to the housing part such that the support and the flow obstructions are arranged downstream of the separation stage in the housing part and that the flow obstructions are located transversely to the main flow direction.

[0117] This makes it possible to flexibly and / or easily design a sanitary insert with different housing component variants and with different combinations of disassembly stage, support, flow obstructions, and outlet stage. A further advantage is that the housing component can be manufactured separately from the disassembly stage.

[0118] 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.

[0119] The outlet step can be round, in particular.

[0120] The housing and the disassembly 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 housing is already integrated into a sanitary fitting.

[0121] 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, can also be provided. In this arrangement, the flow obstructions project from a support that is rigidly connected, in particular integrally, to a particularly round outlet step. According to the invention, to solve the aforementioned problem, the method is proposed to comprise the following steps: Inserting the arrangement of flow obstructions into the sanitary fitting through the outlet opening of the sanitary fitting; fixing the arrangement in the sanitary fitting.

[0122] This method makes it particularly easy to integrate flow obstructions into sanitary fittings, even if the disassembly stage is already located in a sanitary fitting.

[0123] 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: Inserting a separating stage into the sanitary fitting; fixing the separating stage; connecting the support to the separating stage in the sanitary fitting in such a way that the support and the flow obstructions are arranged downstream of the separating stage and that the flow obstructions lie transversely to one, in particular the, main flow direction.

[0124] 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 connected to the disassembly stage.

[0125] The process can be designed in such a way that the disassembly stage is inserted into the sanitary fitting through the outlet opening. This makes the process particularly easy to carry out, especially without having to disassemble the sanitary fitting.

[0126] 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 is inserted together with the disassembly stage, 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.

[0127] 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.

[0128] In particular, the procedure can be used to insert the sanitary insert described here into a sanitary fitting.

[0129] 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: Inserting the separation stage with the arrangement and the outlet stage into the sanitary fitting; fixing the separation stage in such a way that the support and the flow obstructions are arranged downstream of the separation stage and that the flow obstructions lie transversely to one, in particular the, main flow direction.

[0130] The process can be designed in such a way that the disassembly stage is inserted into the sanitary fitting through the outlet opening. This makes the process particularly easy to carry out, especially without having to disassemble the sanitary fitting.

[0131] The method can additionally provide that a housing part is inserted into the sanitary fitting, particularly through the outlet opening of the fitting. The disassembly stage can be connected to the housing part, whereby the housing part can be inserted first and then the disassembly stage inserted, the disassembly stage being fixed in place by connecting it to the housing part, for example, by means of a disassembly stage connection, and in particular by means of the disassembly stage connection described here. The support and the flow obstructions are then arranged downstream of the disassembly stage in the housing part.

[0132] This method also 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 housing component variants and different combinations of disassembly stage, support, flow obstructions, and outlet stage.

[0133] In particular, the procedure can be used to insert the sanitary insert described here into a sanitary fitting.

[0134] 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 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 circular, 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.

[0135] A key advantage is the ease with which sanitary components, particularly aerators, can be designed to meet a wide range of requirements. For example, by combining the separator stage with various 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. Another advantage is the minimal waste generated in this process.

[0136] 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 insert. The features and associated advantages described therein are transferable to the product series by analogy as features and associated advantages of the product series.

[0137] To solve the aforementioned problem, the features of the further dependent 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 within 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.

[0138] 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.

[0139] 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 at the outset, the connecting part has at least one air guide for supplying air from outside the connecting part into the receptacle.

[0140] The fluidic arrangement includes a connection part, which can be, in particular, the connection part described here. The connection part features a hose connection and a receptacle for a sanitary insert. The hose connection serves to connect a separate hose or can be bonded, for example, by laser welding or other welding processes. The receptacle can be, in particular, a space designed to hold a sanitary insert, such as an aerator, as described here. The receptacle can be open in one direction to allow the sanitary insert, such as the aerator, to be inserted. The receptacle and the hose connection are fluidically connected, allowing a fluid, in particular water, to 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 guide 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. Specifically, 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.

[0141] The design of the air guides 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.

[0142] 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 by analogy as features and associated advantages of the fluidic arrangement.

[0143] In practice, it may be additionally or alternatively provided that the air ducts include a penetration in a wall of the connection piece. This penetration allows for a structurally simple and, in particular, compact design of the air ducts. This is because the connection piece typically already has a wall to support the sanitary fitting. By utilizing the penetrations in the wall, the wall can also serve to conduct air, thus eliminating the need for separate components for air ducting.

[0144] The air guides may also include two or more openings in the wall of the connection part. The wall described in this context may, in particular, be the wall of a sleeve-shaped section of the connection part.

[0145] 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 the downstream end is required, and especially no opening for supplying air to a sanitary insert and / or aerator 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. This allows for the creation of a visually appealing sanitary fitting.

[0146] In practice, it may also be provided that the air conveying means are designed to draw in air from an outlet opening, in particular the outlet opening described here, of a sanitary fitting.

[0147] In this way, even if the sanitary fitting lacks an internal space for air supply as described above, or if an internal 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 invisibly concealed, particularly for the 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 a ring cross-section fluidly connected to the outlet opening. Additionally or alternatively, the air guides, 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 an opening in a sanitary fitting in which the receptacle is located.

[0148] Furthermore, in practice, the air guides may be formed on an inner surface that defines the receptacle. In particular, the air guides may be formed within a threaded area. This threaded area may be located on the inner surface that defines the receptacle. For example, the threaded area may be formed by the internal thread of the connecting part as described above.

[0149] In this way, an aerated jet can also be generated if the sanitary fitting lacks the described internal space for air supply, or if an internal space is unsuitable for air supply. Here too, the air guides for air intake can be designed to be invisible to the user. The air guides for air intake can be designed, in particular, as a flowable partial annular cross-section and / or a ring cross-section. Additionally or alternatively, the air guides, especially 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 a housing part of a sanitary insert part and / or a sanitary fitting inserted into the receptacle.

[0150] 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.

[0151] 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. Specifically, an aerated jet can be generated regardless of whether the sanitary insert and / or the aerator itself has means for introducing air into a fluid, especially water, as intended. In other words, this application allows an aerated jet to be generated even if the sanitary insert does not have any means for introducing air.

[0152] In particular, the use described here may relate to the use of a connecting part of the fluidic arrangement described here.

[0153] 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 be effected via an interior of a sanitary fitting that accommodates the fluidic arrangement.

[0154] Additionally or alternatively, air can be supplied via an outlet opening, in particular the outlet opening of a sanitary fitting described here.

[0155] Additionally or alternatively, air can be supplied between the sanitary insert and an inner surface of the connection part that limits the intake.

[0156] In connection with the use of the connecting 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 connecting part.

[0157] The invention will now be described in more detail by means of exemplary embodiments, but is not limited to these embodiments. 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.

[0158] It shows Fig. 1 shows a first variant of a sanitary insertion unit in its intended use in an outlet piece of a sanitary fitting, in an axial section; Fig. 2 shows the sanitary insertion unit made of Fig. 1 in a opposite Fig. 2 Axial section rotated by 90°, Fig. 3 the sanitary insertion unit made of Fig. 1 in an isolated sectional view, in a view from obliquely above onto the section plane, Fig. 4 the sanitary insertion unit made of Fig. 1 in an isolated sectional view, in a frontal view of the section plane, Fig. 5 the sanitary insertion unit made of Fig. 1Fig. 6 shows a second variant of a sanitary insertion unit in an isolated axial section view from below, looking obliquely at the section plane; Fig. 7 shows a third variant of a sanitary insertion unit in an isolated axial section view from below, looking obliquely at the section plane; Fig. 8 shows a fourth variant of a sanitary insertion unit in an isolated axial section view without a drain step, looking obliquely at below; Fig. 9 shows the sanitary insertion unit made of Fig. 8 , with a discharge step, in an isolated sectional view, in a frontal view of the section plane, Fig. 10; a fifth variant of a sanitary insertion unit in an isolated view, without a discharge step, in a view from a low angle, Fig. 11; the sanitary insertion unit made of Fig. 10, with a discharge step, in an isolated sectional view, in a frontal view onto the section plane, Fig. 12 a sixth variant of a sanitary insertion unit in an isolated view, without a discharge step, in a view from below at an angle, Fig. 13 a seventh variant of a sanitary insertion unit in an isolated view, without a discharge step, in a view from below at an angle, Fig. 14 a seventh variant of a sanitary insertion unit in an isolated sectional view, in an oblique view onto the section plane, Fig. 15 an eighth variant of a sanitary insertion unit in an analogous view to Fig. 14Fig. 16 a schematic representation of an arrangement of flow obstructions in a further variant, in a sectional view, in a view onto the section plane, Fig. 17 a schematic representation of an arrangement of flow obstructions in a yet further variant, in a sectional view, in a view onto the section plane, Fig. 18 an isolated representation of the lowest level of the arrangement of flow obstructions of the in Fig. 13Fig. 19 shows a variant of a sanitary insertion unit, in a view from an oblique top; Fig. 20 shows an isolated representation of an arrangement of flow obstructions; Fig. 21 shows an isolated representation of an arrangement of flow obstructions in a further variant, in an oblique view from an oblique top; Fig. 21 shows a variant of a sanitary insertion unit in its intended use in an alternative outlet of a sanitary fitting, in a view analogous to Fig. 2 , Fig. 22 the in Fig. 1 The intended use shown in a further sectional view, in an oblique view of the section plane, Fig. 23, is shown in Fig. 1 The intended use shown in a further sectional view, in an oblique view of the section plane, Fig. 24, the connecting part of the Fig. 1 The variant shown is in an isolated representation, in a side view.

[0159] The figures are described collectively below, where appropriate. Structurally and / or functionally similar or identical components and functional units are designated with matching reference symbols and are not described separately again.

[0160] The Figures 1 to 5 The figures show the same embodiment of a sanitary insert designated as a whole by the number 1, which is designed by way of example as an aerator. Figures 1 and 2 Figure 1 shows the sanitary insert 1 in its intended use. The sanitary insert 1 is attached to a connecting part 2 in an outlet piece 3, for example, on an outlet pipe of a sanitary fitting (not shown). Figures 3 to 5 show the sanitary insert 1 in isolated representation from different perspectives, whereby in Figure 5 For better clarity, part of the housing of the sanitary insert is not shown.

[0161] For those in the Figures 1 and 2 The depicted fastening of the sanitary fitting part features a connecting part 2 with at least one retaining projection 4, which is attached to the outlet piece 3 by a corresponding recess or shoulder 5, in a manner known per se. The connecting part 2 can be fastened, for example, by inserting it into the outlet piece 3 through an outlet opening 11 of the outlet piece 3, from which water is intended to flow from the sanitary fitting. The connecting part 2 can be elastically deformed so that the retaining projection can move past the shoulder 5 and rest in a recess above the shoulder.

[0162] There are also known variants in which the connecting part has an external thread that can be screwed onto a corresponding internal thread formed on the outlet piece, or in which 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.

[0163] The sanitary insert 1 comprises a housing part 8, a separation stage 6, a mixing stage 7 located downstream of the separation stage 6, and a round outlet stage 19 located downstream of the mixing stage 7. In other words, the mixing stage 7 is fluidically downstream of the separation stage 6, and the outlet stage 19 is fluidically downstream of the mixing stage 7. A support 33 of the mixing stage 7 and the outlet stage 19 are rigidly connected to each other, with the rigid connection being achieved by the support 33 being formed integrally with the outlet stage 19.

[0164] 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 8 has an external thread 12 which is screwed to a corresponding internal thread 13 of the connection part 2.

[0165] In further embodiments, the internal counter-thread 13 is formed directly on the outlet piece 3, so that the sanitary insert part 1 can be screwed directly to the outlet piece 3, in particular by means of the housing part 8 (see figure). Fig. 21 and the associated description). A connection part 2 is then not required.

[0166] The sleeve-shaped housing part 8 also serves to form the sanitary insert part 1 as a compact, mechanically stable structure and to seal it off to the outside. As particularly in the Figures 3 and 4As can be seen, 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.

[0167] The housing part 8 is mechanically connected to the disassembly stage 6 via an inflow-side area.

[0168] 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.

[0169] 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 embodiments of the separation stage are also conceivable, for example in the form of a diffuser. To separate the incoming water, a [missing information] is required, particularly in the Figures 3 and 5 The arrangement of holes 27, as shown, is incorporated into the disassembly 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. In alternative variants 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.

[0170] The disassembly plate 6 is located in the Figures 1 and 2The sanitary insert 1 is arranged orthogonally to a direction 14 in which it is intended to be inserted into the sanitary unit, as shown in the intended use. As a result, the individual jets flow out of the holes 27 in a direction essentially opposite to this direction 14.

[0171] The connection of the disassembly plate 6 to the sleeve-shaped housing part 8 is effected by a positive-locking, captive disassembly step connection, which is particularly evident in the Figures 3 and 4 This connection allows different types of housing parts to be combined with different types of disassembly stages.

[0172] The disassembly step connection is designed as a snap connection, for which the disassembly plate 6 has a feature on a circumferential edge, particularly in Figure 5The recognizable, circumferential elastic ring 17 and the sleeve-shaped housing part 8 on the inside form a particularly in the Figures 3 and 4 The retaining projection 18, which can be identified as circumferential and projects inwards into the interior space 10, is wedge-shaped on its downstream side. . It has a wall that rises inwards along direction 14. This allows the disassembly plate 6 to be inserted into the housing part 8 from an outflow side in direction 14 and moved past the retaining projection 18. As the disassembly plate 6 moves 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, then rests on the upstream side of the retaining projection 18.

[0173] For sealing a gap 28 existing between the disassembly plate 6 and the housing part 8, as shown in the Figures 3 and 4A sealing element designed as a sealing ring 29 is located on the upstream side of the gap 28 on the disassembly plate 6 and the gap 28, 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 disassembly stage 6. The sealing ring 29 also seals the sanitary insert part 1 against the connection part 2 by bearing with an upstream side of the sealing ring 29 against an downstream side of the connection part 2. Figure 5 The sealing ring 29 is not shown, but is nevertheless present in principle.

[0174] In an alternative variant of the sanitary insert 1, the disassembly stage is formed in one piece with the housing part 8 (see Fig. 6and the associated description). In yet another variant, no housing part 8 is provided and the disassembly stage 6 is inserted directly into the connection part 2 or into the outlet piece 3, for example via a connection according to the disassembly stage connection described here (not shown).

[0175] The mixing stage 7 is formed by the support 33 located in the interior 10 and by an arrangement 41 of flow obstructions 32 lying transversely to the direction 14 in which the sanitary inlet part 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 inlet part 1 is flowed through. Thus, the flow obstructions 32 project from the support 33 in such a way that they also lie transversely to the main flow direction 25.

[0176] As in the Figures 1, 2 and 4As can be seen, at least one ventilation passage 9 leading into the mixing stage 7 is formed in the sanitary insertion part 1.

[0177] 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 the figures), air flows from the air volume in the outlet piece 3 to the housing part 8 and along the housing part 8 to the Figure 4 ventilation openings 24, formed in the housing part 8, as shown.

[0178] A total of four ventilation openings 24 are formed, of which in Figure 4Due to the sectional view, only two are shown. 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 separation 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 for a distributed introduction of the air. In particular, the ventilation openings 24 are arranged on the inflow side of a first level 38 of the flow obstructions 32, which will be described in detail later, and on the outflow side of the separation stage 6.In this case, a distance A between an outflow-side end of the ventilation opening 24 and the separation stage 6 corresponds to at least 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 through the ventilation openings 24 out of the sanitary insert 1 when the sanitary insert 1 is tilted and / or the water pressure is low.

[0179] Within 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 distributed and transported efficiently within the mixing stage 7.

[0180] Not shown in the figures, but conceivable, is a variant of the sanitary insert in which no means for ventilation are provided. This could, for example, be based on the Figures 1 to 5 The ventilation windows 24 can be omitted, so that an unventilated jet can be generated.

[0181] Downstream of the annular space, the flow obstructions 32 are arranged in at least two levels, namely three levels 38, 39, 40, when viewed in the main flow direction 25. This allows for good mixing in the manner of a cascade when water flows through the sanitary inlet section 1 as intended. At least two, namely all three levels 38, 39, 40 are aligned parallel to each other. The flow obstructions 32 in the different levels 38, 39, 40 each have parallel orientations to each other, as for example in the Figures 3 and 5This can be seen. The flow obstructions 32 of the first level 38 and the third level 40 lie exactly one above the other in the main flow direction 25, and the flow obstructions 32 of the second level 39 are laterally offset to this. As can be seen in particular in Figure 4 As can be seen, two adjacent floors overlap in the main flow direction 25 by a small section, with the overlap of the third floor 40 with the second floor 39 being somewhat more pronounced than the overlap of the second floor 39 with the first floor 38. As a result, the floors 38, 39, 40 are arranged in a nested arrangement.

[0182] 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 this variant 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.

[0183] 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.

[0184] 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 that fluidically connect the two sub-chambers 34, 35. The pressure equalization recesses 36 are so large that the essentially wall-like support 33 is reduced to the central pillar 53 and a plurality of flat webs that connect the flow obstructions 32 at specific points.

[0185] 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-chambers 34, 35. In particular, pressure equalization between the sub-chambers 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.

[0186] 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 when a water jet is discharged as intended.

[0187] The flow obstructions 32 exhibit a particularly pronounced characteristic in the Figures 3 and 4The non-circular cross-section 30, which is realized in particular in the form of a rectangle with rounded corners, is recognizable. 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., across the floors adjacent along the main flow direction 25, this length ratio increases slightly because the extent of the cross-section 30 transversely to direction 25 decreases, while the extent of the 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.

[0188] 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.

[0189] In other alternative variants of the sanitary insert 1, the cross-sections are elliptical or oval, as for example in Fig. 9 and Fig. 11 can be seen.

[0190] 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.

[0191] 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.

[0192] To prevent the support 33 and the flow obstructions 32 from deforming, or deforming only minimally, under the load of the impinging water jets, the mixing stage 7 has a support structure 42 that supports the support 33 and the arrangement 41 of flow obstructions 32 in the main flow direction 25 at the outlet stage 19. The support structure 42 is, as shown in particular in the Figures 4 and 5The structure is recognizable as 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 disassembly stage 6. The webs 42 engage radially outward flow obstructions 32 and are inclined radially outward 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 webs 42 rest on the outlet stage 19. This allows the support 33 with the flow obstructions 32 to be supported as needed or to oscillate freely with respect to the outlet stage 19. The thin, flat webs 42 have only a minimal influence on the intended flow and are simultaneously ideally suited for a predetermined force input initiated by the water flow.

[0193] The phase-out stage 19 is, as particularly in Figure 5The outlet structure 20 has a discharge structure 20 with a round circumferential rim 21. In a central section, the discharge structure 20 features a grid structure 22 and a plurality of openings 23. The grid structure 22 has grid elements aligned parallel to the main flow direction 25 for flow alignment, and the openings 23 are honeycomb-shaped between them. In a radially outer ring section adjacent to the circumferential rim 21, the discharge structure 20 has larger, semi-annular openings 26. The circumferential rim 21 corresponds to the inner wall of the housing part 8.

[0194] 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 supported discharge stage 19 has no further fastening, for example, to the housing 8 or a direct fastening to the separation stage 6.

[0195] Depending on the embodiment of the sanitary insert described here, the housing part 8 and the outlet stage 19 are not mandatory components of the sanitary insert.

[0196] Figure 6 shows an alternative variant of the sanitary insert 1. This variant is similar to the one in the Figures 1 to 5The variant shown is shown. Therefore, only the existing differences between the two variants will be described below.

[0197] At the in Figure 6 In the variant shown, the disassembly stage 6 and the housing part 8 are not connected to each other, but are formed as a single piece. Therefore, the previously described disassembly stage connection is unnecessary. This one-piece design is particularly well sealed and mechanically stable.

[0198] In order to enable the insertion of the support 33 in the direction 14, in which the sanitary insert 1 is intended to be inserted into the sanitary unit, the following is necessary in the Figure 6In the variant shown, the support 33 is not formed integrally with the disassembly stage 6, but rather the support 33 can be connected to the disassembly stage 6 via a connection 43. This 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 discharge stages 19.

[0199] Connection 43 is designed as a locking, captive connection.

[0200] The connection 43 has a symmetry-breaking interface 44, the interface 44 defining an alignment of the flow obstructions 32 relative to the disassembly stage 6 with respect to rotations about a longitudinal axis. Thus, an alignment of the flow obstructions 32 with the rows 37 of holes 27 in the disassembly stage 6 can be easily achieved. For the symmetry-breaking interface 44, the disassembly stage, designed as a disassembly plate 6, has a central, asymmetrical recess that can be accessed in an orientation parallel to the main flow direction 25. The support 33 has a projection geometrically corresponding to the recess and spring-loaded locking lugs 51 engaging the projection. The support 33 can thus be moved into the recess with the projection against the main flow direction 25.When the locking lugs 51 have penetrated the recess, they can spring up and thus hold the carrier 33 securely in the disassembly plate 6.

[0201] Alternative variants of the sanitary insert 1 with other types of connection 43 are the Figure 14 and 15 shown. These variants resemble the one in Figure 6 The variant shown is therefore only described in terms of its existing differences. In particular, the following applies to the Figure 14 and 15 For better illustration of the respective connection 43, the housing part 8 is not shown. The in the Figure 14 and 15 The disassembly stage 6 shown can either be analogous to the variant of the Figures 1 to 5 be connectable to housing part 8 or analogous to the variant of the Figure 6 be formed in one piece with the housing part 8.

[0202] The in the Figure 14 and 15The connection 43 shown can function in a similar way. The connections 43 shown can be configured as a latching connection.

[0203] The compounds shown (43) differ from each other in that the in Figure 14 The variant shown allows free orientation 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 one in Figure 15 shown variant, as in Figure 6 The variant shown determines a forced alignment of the support 33 and the arrangement 41 of flow obstructions 32 relative to the disassembly stage 6.

[0204] For the in Figure 15In the forced alignment of the support 33 and the arrangement 41 shown, the support 33 engages with its flat wall 54 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 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.

[0205] At the in Figure 14 In the variant shown, 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. Figure 15In the variant shown, the support 33 does not engage with the slots 46. The 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.

[0206] Figure 7 shows another alternative variant of the sanitary insert 1. This variant also resembles the one shown in the

[0207] Figures 1 to 5 The variant shown. Therefore, only the existing differences between the two variants will be described below.

[0208] The in Figure 7 The variant shown features connection 43, which is associated with the one in Figure 6 The variant shown is described. This variant can alternatively also be the one described in the Figure 14 or 15 Compound 43 shown. Furthermore, the compound shown in Figure 7 shown variant which is related to the one in the Figures 1 to 5 described disassembly stage connection. This variant therefore differs from the one described in the Figures 1 to 5 The variant shown is made possible by the fact that the disassembly stage 6 and the support 33 can be connected to each other. This allows for a particularly high degree of flexibility with regard to the combinability of different variants of disassembly stages 6, supports 33, arrangements 41 of flow obstructions 33 and / or discharge stages 19.

[0209] The Figure 8 and 9 show another alternative variant of the sanitary insert 1. This variant also resembles the one shown in the Figures 1 to 5 shown variant. Therefore, only the existing differences between the two variants will be described below. Figure 8 For better visibility, housing part 8 and outlet stage 19 are not shown. Figure 9 Housing part 8 is not shown.

[0210] As shown by the Figure 8 and 9As can be seen, the disassembly stage 6 is also designed as a basic body with a three-dimensional structure in the form of a disassembly plate 6. On the outflow side 15 of the disassembly plate 6 facing the mixing stage 7, a plurality of air channels 16 are incorporated as recesses 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 disassembly plate 6 to the wall 54 of the support 33 at the centerline of the outflow side 15 of the disassembly plate 6. The holes 27 arranged in one of the common rows 37 open into an air channel 16 that is 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.

[0211] The air ducts 16 form one section of the ventilation passage 9. The air flows from the area associated with the Figures 1 to 5 The described annular space flows 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.

[0212] On the downstream side below the air ducts 16, as with the variants of the Figures 1 to 7 , the flow obstacles 32 arranged. In the Figure 8 and 9In the variant shown, 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.

[0213] Particularly due to the modified cross-section 30, the wall of the support 33 and the pressure equalization recess 36 are also shaped 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 several of the cross-sections 30 described here are combined.

[0214] During the Figure 8 and 9 The variant shown is the one related to the Figures 1 to 5The described ring 17 of the disassembly step connection is also modified. The one in the Figure 8 and 9 The wreath shown (number 17) can be found in the Figures 1 to 5 The wreath shown can be replaced, and vice versa.

[0215] The Figures 10 and 11 show another alternative variant of the sanitary insert 1. This variant is similar to the one in the Figure 8 and 9 The variant shown is shown. Therefore, only the existing differences between these two variants will be described below.

[0216] The flow obstructions 32 of the in the Figures 10 and 11 The variant shown is arranged in three levels 38, 39, 40. The flow obstructions 32 of the first level 38 and of the third level 40 are located as in the Figures 1 to 5In the variant shown, the two levels are stacked on top of each other, and the second level 39 is laterally offset from this. The non-circular cross-section 30 of the flow obstructions 32 in the first level 38 and the second level 39 is, as in the one shown in the Figure 8 and 9 The variant shown is elliptically shaped. 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 in the first level 38 and the second level 39.

[0217] 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.

[0218] The Figure 12 shows another alternative variant of the sanitary insert 1. This variant also resembles the one shown in the Figures 1 to 5 shown variant. Therefore, only the existing differences between the two variants will be described below. Figure 12 For better visibility, housing part 8 and outlet stage 19 are not shown.

[0219] At the in Figure 12In the variant shown, 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.

[0220] The Figure 13 shows another alternative variant of the sanitary insert 1. This variant also resembles the one shown in the Figures 1 to 5 shown variant. Therefore, only the existing differences between the two variants will be described below. Figure 13For better visibility, housing part 8 and outlet stage 19 are not shown.

[0221] At the in Figure 13 In the variant shown, 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 35 in the main flow direction, has at least two, namely three, areas 48, 49, 50 of flow obstructions 32. These areas are also in Figure 18 , which isolates the lower level 40 of the arrangement 41 described here from flow obstructions 32. In the arrangement described here and in the Figure 13 and 18In the arrangement 41 shown, the orientation of the flow obstructions 32 differs in 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 38.

[0222] 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.

[0223] The Figure 14 and 15 are related to Figure 6 described.

[0224] Figure 16Figure 41 shows a further variant of the arrangement 41 of flow obstructions 32 in a schematic representation. In this arrangement, 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 above, which are 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.

[0225] Figure 17Figure 41 shows a further variant of the arrangement 41 of flow obstructions 32 in a schematic representation. In this 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 arrangement 41, the levels 38, 39 overlap analogously to the arrangement described in Figure 41. Figure 4 described. This arrangement 41 can also be combined with the described mixing stage 7 and / or the described sanitary insert 1.

[0226] Figure 18 shows in isolation the lowest level 40 of the arrangement 41 of flow obstructions 32 of the in Figure 13 shown variant of a sanitary insertion device 1 and is related to Figure 13described. The isolated representation 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 side 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, in the main flow direction 25, overlap section by section.

[0227] Figure 19 Figure 41 shows yet another variant of the arrangement 41 of flow obstructions 32. This variant is similar to the one in Figure 32. Figure 18shown, lowest level 40 of the arrangement 41 of flow obstructions 32. Therefore, only the existing differences between the two variants will be described below. In contrast to the one shown in Figure 18 In the variant shown of the arrangement 41 of flow obstructions 32, the arrangement 41 described here has only one level, namely level 40, which is similar to the third level 40 in the main flow direction 25. Figure 13 is formed. 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 area 48 can be connected to each other by a holder 52. The flow obstructions 32 of the second area 49 and the third area 50 can be connected as in connection with Figure 18described, be designed. The arrangement 41 described here can be combined with the described mixing stages and / or sanitary insertion devices.

[0228] Figure 20 Figure 1 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 levels 38, 39. The support 33 differs from the support 33 shown in the Figures 1 to 5 The variant shown is formed. In the Figure 20 In the variant shown, the support 33 also consists of the central, round pillar 53, which is firmly connected to the disassembly plate 6, and the thin wall 54. However, the wall 54 is not, as in the Figures 1 to 5The flow obstructions 32 are not shown as separate units, but rather as a ring that radially surrounds the arrangement 41 of flow obstructions 32. In particular, each of the levels 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.

[0229] Figure 21 shows a use of the sanitary insert in an analogous view to the one in Figure 2 The use shown is similar to that described in the Figures 1 and 2 The use and arrangement shown are described below. Therefore, only the existing differences are described below. The following is a description of the use and arrangement shown below. Figure 21 The usage shown differs from that in Figure 2The application shown is made possible by the fact 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.

[0230] The Figures 22 to 24 show the in Fig. 1 The intended use shown, or the connecting part 2, is illustrated in further sectional views. Based on the Figures 22 to 24 A fluidic arrangement and the use of a, in particular the, fluidic arrangement are also recognizable.

[0231] The fluidic arrangement includes 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 separate hose (not shown). The receptacle 56 is designed as a chamber that serves to receive the sanitary insert 1. The receptacle 56 can be open, particularly in the intended main flow direction, to allow the sanitary insert 1 to 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, 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, it 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.

[0232] 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 insertion part 1 via connection part 2.

[0233] In the variant shown here, the air guides 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.

[0234] In variants of the fluidic arrangement, the air guides 57 are configured to draw in air from the outlet opening 11 of the sanitary fitting 59 (not shown).

[0235] As particularly in Figure 24As can be seen, the air guides 57 are at least partially also formed on an inner surface 61 limiting the intake 56 in a threaded area 62, namely on the internal thread 13.

[0236] 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 1, which is inserted into a receptacle 56 of the fluidic arrangement. The information related to the Figures 1 to 24The described arrangement 41 of flow obstructions 32, which project 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 discharge stage 19, which is in particular round. In this application, the support 33 with the flow obstructions 32 and the discharge stage 19 can be arranged, in particular, on the downstream side of the separation stage 6.

[0237] As shown by the Figures 1 to 20 and as can be seen from the associated description, a method for forming a sanitary insert 1 is also described, wherein the method comprises the following steps: Providing a separation stage 6 and an arrangement 41 of flow obstructions 32, which project from a support 33 which is rigidly connected, in particular integrally, to a particularly round outlet stage 19; joining the support 33 and the separation stage 6, in particular against the intended main flow direction 25; connecting the support 33 with the separation stage 6 such that the support 33 and the flow obstructions 32 are arranged downstream of the separation stage 6 and that the flow obstructions 32 lie transversely to the main flow direction 25.

[0238] As also shown by the Figures 1 to 24 and as can be seen from the associated description, a further method for forming a sanitary insert 1 is described, wherein the method comprises the following steps: Providing a housing part 8 and a separation stage 6, wherein the separation stage 6 is rigidly connected, in particular integrally, to a support 33 and the support 33 is rigidly connected, in particular integrally, to a particularly round outlet stage 19, wherein an arrangement 41 of flow obstructions 32 projects from the support 33; joining the housing part 8 and the separation stage 6, in particular against the intended main flow direction 25; connecting the separation stage 6 to the housing part 8 such that the support 33 and the flow obstructions 32 are arranged downstream of the separation stage 6 in the housing part 8 and that the flow obstructions 32 lie transversely to the main flow direction 25.

[0239] Furthermore, based on the Figures 1 to 24and the associated description shows that a method for introducing an arrangement 41 of flow obstructions 32 into a sanitary fitting is described, wherein the flow obstructions 32 project from a support 33 which is firmly connected, in particular integrally, with a particularly round outlet step 19 and wherein the method comprises the following steps: Inserting the arrangement 41 of flow obstructions 32 into the sanitary fitting through the outlet opening 11 of the sanitary fitting; fixing the arrangement 41 in the sanitary fitting.

[0241] 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 sanitary fitting, the following additional steps may be provided, wherein the support 33 is firmly connected, in particular in one piece, with a particularly round disassembly stage 6: 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; 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.

[0242] 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, wherein the disassembly stage 6 of both variants can be connected to a support 33 that can be arranged downstream of the disassembly stage 6, as for example in the Figure 6 , 14 or 15The support 33 is rigidly connected, in particular integrally, to a downstream, in particular round, outlet step 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 Figures 8 to 24 The variants of the arrangement 41 of the flow obstructions 32 shown can be formed on a support 33 which can be connected to the disassembly stage 6.
