Description

The invention relates to a sanitary inserting unit with a jet regulator, which has a jet regulator housing with a housing inlet and a housing outlet, which jet regulator housing has a jet separator in its housing interior.

Various insertion units have already been provided which can be mounted on the water outlet of a sanitary outlet fitting in order to form the water emerging there into a homogeneous, non-spraying and possibly also soft, soft water jet. The previously known insertion units have for this purpose a jet regulator with a jet regulator housing, in whose housing interior the water flowing through can be mixed with ambient air. The aerator housing such aerated jet regulator has a housing inlet connected to the clear cross section of the water outlet of the sanitary outlet fitting and a housing outlet, wherein the jet regulator housing has in its housing interior a jet splitter, which can be configured as a cup-shaped diffuser or as a perforated plate. In a designed as a cup-shaped diffuser jet disintegrator of the pot bottom serves as a baffle, which is the beam splitter deflects incoming water to the outside. In this case, flow openings are provided in the peripheral wall of the cup shape, through which the water can flow. The throughflow openings open into an annular channel, which is formed between the outer circumference of the cup-shaped diffuser and a diffuser ring enclosing the diffuser. In the through-flow openings of the diffuser and also in the annular channel, which tapers in the direction of flow, the water flowing through undergoes an increase in speed which, according to the Bernoulli equation, results in a negative pressure downstream. Due to this negative pressure ambient air is sucked in, which can enter into the housing interior through ventilation openings in the housing peripheral wall of the jet regulator housing. The previously known insertion units with their jet regulator, the jet regulator housing, the jet separator located in the jet regulator housing and the ventilation openings provided in the housing peripheral wall of the jet regulator housing have a certain installation length, which necessitates a correspondingly long outlet nozzle. Since the outlet mouthpiece is regularly made in the outer presentation of the outlet fitting and there color differences between the. Outlet fitting and a separately produced outlet nozzle are perceived disturbing, the production of such an insertion unit and the associated outlet nozzle is associated with a considerable manufacturing effort.

It is the object to provide a sanitary inserting unit of the type mentioned, whose production and assembly is associated with a significantly reduced effort.

A solution to this problem according to the invention consists, in particular, in that the insertion unit is ventilated Jet regulator has its jet divider is designed as a cup-shaped diffuser, the bottom of the pot serves as a water flowing through the deflecting outwardly deflecting baffle and in the peripheral wall of its cup shape has at least one flow opening, which opens into an annular channel, wherein the jet regulator in a Gehäuseumfangswandung its jet regulator housing has at least one ventilation duct whose Kanalauslassöffnung opens in the housing interior of the jet regulator housing, wherein the housing outlet facing the opening edge of the Kanalauslassöffnung is arranged above a running through the outlet end face of the jet separator cross-sectional plane of the jet regulator housing.

The sanitary inserting unit constructed in accordance with this invention proposes a ventilated jet regulator which has a jet regulator housing with a housing inlet and a housing outlet. In the housing interior of the jet regulator housing a jet splitter is provided, which is designed as a cup-shaped diffuser. This cup-shaped diffuser has a bottom of the pot, which serves as a deflecting the water flowing through outward baffle. In the peripheral wall of the cup-shaped diffuser at least one flow opening is provided which opens into an annular channel, wherein the jet regulator has in a Gehäuseumfangwandung its jet regulator housing at least one ventilation channel, the channel outlet opens in the housing interior of the jet regulator housing. In this case, the opening edge of the channel outlet opening facing the housing outlet is arranged above a cross-sectional plane of the jet regulator housing extending through the outlet-side end face of the jet breaker. In the case of the jet regulator used in the sanitary inserting unit according to the invention, a clear reduction in the height and a considerable reduction in height can be achieved Reduction of the mixing chamber volume reach the mixing chamber downstream of the jet splitter in the flow direction. In this mixing chamber, the water flowing through the inserting unit is mixed with ambient air before the thus aerated water, if appropriate, flows out of the housing outlet of the jet regulator into the atmosphere via an outlet-side flow rectifier. Since the housing outlet facing the opening edge of the channel outlet opening of the at least one ventilation duct is disposed above a running through the outlet side end face of the jet separator cross-sectional plane of the jet regulator housing, the at least one ventilation duct in the Gehäuseumfangswandung the jet regulator housing can be positioned extremely high up towards the housing inlet, so that the Lower edge of the channel opening of the at least one ventilation duct is arranged above the lower end of the designed as a diffuser jet breaker. Due to the extremely short and compact design of the inserting unit according to the invention, only a correspondingly short outlet nozzle is required, whereby the effort associated with the production of the inserting unit according to the invention and its outlet nozzle is considerably reduced.

In this case, a preferred development according to the invention provides that the housing outlet facing the opening edge of the channel outlet opening of the at least one ventilation channel is arranged above a running through the outlet side channel opening of the annular channel cross-sectional plane. In this further embodiment, the opening edge facing the housing inlet of the channel outlet opening of the at least one ventilation channel opening in the interior of the housing is even above a cross-sectional plane running through the outlet-side channel opening of the annular channel. Due to this exceptional location of at least a ventilation duct, a particularly good and intensive mixing of the sucked into the housing interior air is achieved with the accelerated in the preferably tapered annular channel water; The highly positioned arrangement of the at least one ventilation channel on the housing peripheral wall of the jet regulator housing simultaneously prevents water from being able to splash out through the at least one ventilation channel, thereby preventing the intake of further ambient air.

In order to generate a high negative pressure in the area of the mixing chamber adjoining the annular channel, by means of which ambient air can be sucked into the interior of the housing through the at least one ventilation channel, it is advantageous if the annular channel extends in the direction of its outlet-side channel opening at least in a partial section rejuvenated. In this case, a preferred embodiment according to the invention provides that this annular channel tapers conically towards its outlet-side channel opening.

Another proposal of its own worthy protection provides for the sanitary inserting unit of the type mentioned above to solve the above problem that the inserting unit has a vented jet regulator with a jet disintegrator, which is designed as a cup-shaped diffuser whose pot bottom as a water flowing through The deflector serves at least in the peripheral wall of its cup shape, which opens into an annular channel, wherein the jet splitter at least partially projects into a diffuser ring and bounded between the ring and the diffuser ring, the diffuser ring in a outlet side housing part of the Radiation regulator housing is used until an outer peripheral side arranged on the diffuser ring Ring shoulder rests on an inlet-side mating surface on the outer side housing part, wherein the outer circumference of the circumferential ring is provided on the diffuser ring, which is latched with a provided on the outlet side housing part inside peripheral locking groove and wherein the locking cam has a ramp, which cooperates with a locking groove in the direction of insertion upstream skew, which counter-slope compared to the ramp has a greater angle of inclination than the jet regulator longitudinal axis.

In this insertion unit according to the invention, which can be implemented in addition to or instead of the above-mentioned invention proposal, the aerated jet regulator on a jet breaker, which is designed as a cup-shaped diffuser, the pot bottom of this diffuser serves as a water flowing through the outwardly deflecting baffle and wherein in the peripheral wall of the pot shape at least one flow opening is provided. This diffuser designed as a diffuser is at least partially in front of a diffuser ring, which limits the annular channel between itself and the diffuser. The diffuser ring can be inserted into an outflow-side housing part of the jet regulator housing until an annular shoulder arranged on the outer circumference of the diffuser ring rests on an outlet-side counter-surface on the outlet-side housing part. In order to connect the diffuser ring to the outlet-side housing part firmly, yet releasably, a circumferential locking cam is provided on the outer circumference of the diffuser ring, which can be latched with a locking groove arranged on the outlet-side housing part. The outer circumference of the circumferential ring on the diffuser ring locking cam has a ramp, which is connected to one of the locking groove in the insertion upstream counter-slope on the outlet side housing part interacts. In this case, this counter-slope in comparison to the run-up slope on the jet controller longitudinal axis greater inclination angle. By this configuration, it is possible to mount the diffuser ring on the one hand and the outlet side housing part on the other hand also in an automated manufacturing process at high speed. Due to the geometric configuration of ramp and counter-slope, the expansion rate at the outlet side housing part is not as large as, for example, in a design with inlet radii. This lower strain rate during rapid assembly can effectively prevent expansion cracks in the outlet-side housing part during the assembly process and also lower assembly forces are the result of this limiting latched snapping or snapping.

In this case, a preferred embodiment according to the invention, that the inclination angle of the counter bevel between 40 ° and 50 ° and that of the ramp is between 30 ° and 40 °. Preferred is an embodiment in which the inclination angle of the counter bevel is about 45 ° and that of the ramp is about 35 °.

According to a further suggestion of its own worthy of protection, which can be implemented in addition to or instead of the inventive proposals described above, the jet regulator with its jet regulator housing in a water outlet of a sanitary outlet fitting mountable outlet nozzle is used, wherein the jet regulator is axially sealed by a sealing ring, the between the jet regulator and the outlet-side end edge of the outlet fitting is clamped, wherein the jet regulator has on its inlet-side end face an encompassed by the sealing ring wall and wherein the sealing ring on the one hand on the ring wall and on the other protrudes the inflow-side end edge of the outlet mouthpiece.

In this proposed invention, the jet regulator of the insertion unit according to the invention is used with its jet regulator housing in a mounted on the water outlet of a sanitary outlet fitting outlet nozzle. In order to seal the jet regulator housing against the water outlet of the sanitary outlet fitting, an axially sealing sealing ring is provided which can be clamped between the jet regulator and the outlet-side end edge of the outlet fitting. The jet regulator now has on its inflow-side end face an annular wall encompassed by the sealing ring, the sealing ring projecting on the one hand via the annular wall and on the other hand via the inlet-side end edge of the outlet mouthpiece. Especially with a particularly compact design of the inserting unit and its jet regulator, only a very small space is available for the sealing ring required for the axial sealing. Since the sealing ring due to a secure holding in the outlet mouthpiece on the one hand and a required standard projection from the outlet mouthpiece out on the other hand can have a very slim height to thickness ratio, there is a risk that the sealing ring when tightening the outlet nozzle at the water outlet of the sanitary outlet fitting inside collapses, which hinders a secure, tight fastening of the outlet mouthpiece and the insertion unit located therein at the water outlet of a sanitary outlet fitting. However, since the jet regulator of the insertion unit according to the invention has an annular wall encompassed by the sealing ring on its inlet-side end face, the sealing ring is supported against lateral buckling in the case of axial compression by means of the annular wall. In this case, the sealing ring in an interference fit inside circumference on the outlet nozzle, so that the sealing ring both itself and the insertion unit in the assembly the insertion unit in the outlet fitting associated handling and in particular ensures a handling done upside down. However, so that the sealing ring can be pressed into the outlet mouthpiece in a slight press fit, it is expedient if a slight air gap or clearance remains between the sealing ring and the counter-flow direction upwardly projecting annular wall.

A preferred embodiment according to the invention provides that the jet regulator of the insertion unit according to the invention has a jet regulator housing having an inlet-side and a outlet-side housing part, that designed as a diffuser or perforated plate jet splitter can be inserted from the inlet-side housing front side in the inlet-side housing part and that at arranged on the inlet-side end face of the jet breaker, the annular wall, preferably integrally formed, is.

According to another proposal according to the invention of its own worth-worthy importance is provided that the annular wall surrounds a regulator housing a flow regulator unit and / or a header or filter screen. If required, this flow regulator unit can be connected to the attachment or filter screen on its inlet-side end face. In order to secure the flow rate regulator unit on the upstream side of the insertion unit according to the invention safely and yet with little effort, 'it is advantageous if a locking connection is provided between the annular wall and the regulator housing.

The simple production of the insertion unit according to the invention is additionally made much easier when provided between the annular wall and the controller housing latching connection at a distance below the free end edge the annular wall is arranged. Thus, the regulator housing of the flow regulator unit can be inserted into the annular wall, whereby a positionally correct arrangement between the regulator housing of the flow regulator unit and the other components of the insertion unit is ensured. Further pressure on the flow-rate regulator unit centered in the annular wall allows it to be securely and firmly connected to the other components of the insertion unit.

Further developments according to the invention will become apparent from the claims in conjunction with the drawings and the description. Hereinafter, a preferred embodiment according to the invention will be explained in more detail with reference to the drawing.

In the Figures 1 and 2 and FIGS. 3 to 6 show two different embodiments of a sanitary inserting unit 1. The sanitary inserting unit 1 can be inserted into a sleeve-shaped outlet mouthpiece 2, which can be mounted on the water outlet of an outlet fitting (not further shown here). The sanitary inserting unit 1 has a jet regulator 3, which is designed here as a ventilated jet regulator. The jet regulator 3 has a jet regulator housing whose inlet-side housing end face forms a housing inlet 4, while the downstream housing face is designed as a housing outlet 5. In the jet regulator housing a jet splitter 6 is provided, which is designed here as a cup-shaped diffuser. This pot-shaped diffuser has a pot bottom 7, which serves as a baffle, which deflects the water flowing through to the outside. The cup-shaped diffuser has in the peripheral wall of its cup shape at least one flow opening and preferably - as here - several, in particular at regular intervals from each other arranged flow openings 8, which open into an annular channel 9.

The jet regulator 3 has at least one ventilation channel 10 in a circumferential housing wall of its jet regulator housing on, the Kanalauslassöffnung opens inside the housing. By way of this at least one ventilation duct 10, ambient air can be sucked into the housing interior of the jet regulator housing, which is there shaped with the water flowing through it to form a homogeneous, non-spraying and, in particular, even soft, soft water jet.

In order to make the sanitary inserting unit 1 and its jet regulator 3 as compact as possible, the opening edge 11 of the channel outlet opening of the at least one ventilation channel 10 facing the housing outlet 5 is arranged above a cross-sectional plane of the jet regulator housing extending through the outlet-side end face 12 of the jet separator 6. In this way, the overall height of the annular channel 9 in the flow direction following mixing chamber M, in which the mixed with ambient air water is treated, substantially reduce. The at least one ventilation channel 10 is here positioned in the direction of the housing inlet 4 in such a way that the opening edge 11 of the channel outlet opening of the at least one ventilation channel 10 facing the housing outlet 5 is arranged above a cross-sectional plane running through the outlet-side channel opening 13 of the annular channel 9. By this arrangement, the ventilation ducts 10 and their Kanalauslassöffnungen, in which the annular channel 9 on the outside delimiting channel wall covers the Kanalauslassöffnungen the ventilation ducts 10, a particularly good and intensive mixing of the sucked into the housing interior of the jet regulator housing air is achieved with the accelerated in the annular channel 9 water , Through this arrangement, positioned in the direction of the housing inlet 4, of the ventilation channels 10, it is avoided that the water, mixed with ambient air, splashes outwards and thus prevents the intake of further air.

As if from a comparison of FIGS. 1 to 6 becomes clear, the jet splitter 6 projects at least in sections into a diffuser ring 33 which delimits the annular channel 9 between itself and the jet splitter 6. The diffuser ring 33, which is also embodied here as an inflow-side housing part of a substantially two-part jet regulator housing, can be inserted into an outlet-side housing part 26 of the jet regulator housing until an annular circumference 14 arranged on the outer circumference of the diffuser ring 33 rests on an outlet-side counter face on the outlet-side housing part 26. On the outer circumference of the diffuser ring 33, a circumferential locking cam 15 is provided, which can be latched with a locking groove 16 provided on the outlet-side housing part 26 on the inner peripheral side. In this case, the locking cam 15 has a ramp 16 which cooperates with a locking groove 16 in the direction of insertion upstream counter-slope 18.

The counter-slope 18 on the outlet-side housing part 26 has here compared to the ramp 16 on the latching cam 15 of the diffuser ring 33 a relation to the jet regulator longitudinal axis greater inclination angle. As a result of these different angles of inclination of the run-on slope 17 and the counter-slope 18, it is possible to mount the diffuser ring 33 and the outlet-side housing part 26 at high speed, if appropriate also in an automated production and assembly process. Due to the selected geometric configuration of the run-on slope 17 and the corresponding counter-slope 18, the expansion rate at the outlet-side housing part 26 is not so great, as for example in a design with inlet radii. Due to this lower strain rate, expansion cracks on the outlet-side housing part 26 can be effectively prevented during the assembly process, even with rapid assembly; At the same time, even lower assembly forces are sufficient to accomplish the provided between the diffuser ring 33 and the outlet-side housing part 26 latching connection. While the angle of inclination of the counter-slope 18 is preferably approximately 45 °, the run-up slope 17 in contrast has an angle of inclination with respect to the longitudinal axis of the jet regulator of approximately 35 °.

As in the FIGS. 1 to 6 it can be seen, the jet regulator 3 is preceded by a preferably conical intent or filter screen 19. As with the in FIGS. 1 and 2 can be seen, may be disposed between the header or filter screen 19 and the jet regulator 3, a flow regulator unit 20, which has to regulate the flow to the jet regulator 3 per unit time water volume to a predetermined pressure-independent value.

The jet regulator 3 can be used with its jet regulator housing in an outlet nozzle 2 which can be mounted on the water outlet of a sanitary discharge unit. In this case, the jet regulator is inserted from the inflow-side end face into the outlet nozzle 2 until an annular shoulder 21 arranged on the outer circumference of the jet regulator housing rests on an annular shoulder 22 arranged on the inner circumference of the sleeve-shaped outlet nozzle 2. In this case, the jet regulator 3 is axially sealed by means of a sealing ring 23 which is clamped between the jet regulator 3 and the outlet-side end edge of the outlet fitting. Due to the desired compact design of the jet regulator 3 and because of the limited on the inflow side of the jet regulator 3 by the attachment or filter screen 19 and the flow regulator unit 20 space is required for the axial sealing required sealing ring only a very small space. Since this sealing ring 23 for a secure fit in the outlet nozzle 2 and possibly also due to a required standard supernatant may have a very slim height to thickness ratio, there is a risk that the sealing ring 23 collapses when tightening the outlet mouthpiece 2 inwards, whereby a secure and tight fastening of the jet regulator 3 at the water outlet of the sanitary Outlet fitting is obstructed. The jet regulator 3 therefore has an annular wall 24 encompassed by the sealing ring 23 on its inlet-side end face, the sealing ring 23 projecting on the one hand via the annular wall 24 and on the other hand via the inlet-side end edge of the outlet nozzle 2. The annular wall 24 supports the sealing ring 23 formed here as a flat seal in the case of axial compression against lateral buckling. In this case, the sealing ring 23 is press-fit on the inner circumference of the outlet nozzle 2, so that the sealing ring 23 secures both itself and the jet regulator 3, if, for example, the sanitary inserting unit at the water outlet of the sanitary outlet fitting must be mounted in particular upside down. However, in order that the sealing ring 23 can be pressed into the outlet mouthpiece 2 with a slight press fit, it is advantageous if an air gap 25 remains between the sealing ring 23 and the circumferential annular wall 24 protruding counter to the direction of flow.

The jet regulator housing of the jet regulator 3 is designed in two parts here and has the diffuser ring 33, which also serves here as an inlet-side housing part, and an outlet-side housing part 26. In this case, the diffuser configured as a jet separator 6 can be used from the inlet-side housing end face in the diffuser ring 33, which also serves as an inlet-side housing part. At the inflow-side end face of the here as a diffuser designed jet breaker 6, the annular wall 24 is integrally formed. As from the longitudinal sections according to Figures 1 and 2 becomes clear, embraces the ring wall 24, a regulator housing 27 of a flow regulator unit 20. In the controller housing 27 of the flow regulator unit 20, at least one annular channel is provided in which an annular throttle body 29 is located between itself and a, disposed on an inner and / or outer channel wall rule profiling a Limited control gap, which is changeable by the deforming under the pressure of the inflowing water throttle body in its clear gap cross-section.

As if from a comparison of Figures 1 and 2 On the one hand and 3 to 6 on the other hand clear, in the space bounded by the annular wall 24 and a header or filter screen 19 and optionally additionally or instead, the flow regulator unit 20 are inserted. In order to securely hold the attachment or filter screen 19 or the flow rate regulator unit 20 in the free space bounded by the annular wall 24, a latching cam 30 is provided on the inner circumference of the annular wall 24. This locking cam 30 engages behind a arranged on the outer circumference of the regulator housing 27 or on the outer periphery of the attachment or filter screen 19 annular flange 31, 32. Since the inner peripheral side provided on the annular wall 24 locking cam 30 is arranged at a distance from the free end edge of the annular wall 24, which forms between the latching cam 30 and the free end edge of the annular wall 24 remaining Wandungsabschnitt the annular wall 24 a centering, the latching of the controller housing 27 or the intent or filter screen 19 on the locking cam 30 and the locking of the attachment screen 19 to the already latched to the annular wall 24 Regulator housing 27 much easier. The axial spacing of the latching cam 30 from the inflow-side end edge of the annular wall 24 allows an axial extent in which the attachment or filter screen 19 or the attachment screen 19 and Flow control unit 20 existing combination can be imposed during assembly, wherein the applied component due to the configuration of the locking cam 30 and the rounding at the peripheral downstream edge of the attachment or filter screen 19 or on the rounded in the same way circumferential lower edge of the controller housing 27th self-centered. As a result, the assembly process of the attachment or filter screen 19 or consisting of the attachment screen 19 and the flow regulator unit 20 combination on the designed as a diffuser beam splitter 6 is much easier, with only an axial assembly force must be applied for locking, without simultaneously for Centering and alignment of the components to be locked together care is to be taken.

At the outlet-side housing end face of the jet regulator housing, a flow rectifier is formed into a flow-guiding grid or network structure.
