Description

The invention relates to a sanitary functional unit having a housing which is releasably attachable to the water outlet of a sanitary outlet fitting, wherein the housing has a downstream housing face with discharge openings, wherein the downstream housing end face has at least one slot whose opposite slot longitudinal sides as a rotation - Or tool engagement surfaces are designed for a releasably insertable in the at least one slot rotary tool, and wherein the housing of the functional unit is rotatably supported at the water outlet of the outlet fitting.

Various sanitary functional units are already known which can be detachably fastened at the outlet end of a sanitary outlet fitting in order to shape and / or regulate the water jet emerging there. For example, jet regulators have been created which are intended to form the outflowing water into a homogeneous, non-spattering and, if appropriate, also pearly-soft water jet. These, for example, designed as a jet regulator functional units have a housing having a downstream and, for example, as a flow rectifier designed housing end face having a plurality of outflow openings. In order to assemble such known functional units at the outlet end of the outlet fitting, one has already created functional units which carry an external thread on the housing outer circumference of its housing, with which the housing with a provided on the inner circumference of the outlet fitting internal thread can be screwed. In order to be able to apply the rotational force required for screwing the corresponding thread to the housing, profilings are provided on the downstream peripheral edge or on the peripheral edge of the housing to serve as a rotary-action or tool-engaging surface for a turning tool. Since the previously known functional units are usually maintenance-free for many months, the required turning tool is often laid over the months in such a way that it is not readily available when needed.

A jet aerator is known from DE-GM 93 14 990 of the Applicant, which has a perforated plate serving as a jet disintegrator in its installation housing, which has a number of flow holes for generating a plurality of individual jets. Pins are provided in the outflow region of the throughflow holes, whose free and conically tapering pin end pointing towards the perforated plate is designed as a deflection slope which deflects each of the individual beams coming from the throughflow holes obliquely to the flow direction. In order to mount the mounting housing of this known jet aerator on the water outlet of a sanitary outlet fitting, a sleeve-shaped outlet nozzle is provided, in which the installation housing can be used up to an insertion stop. At the outlet mouthpiece a thread is provided, which can be screwed with a corresponding mating thread on the water outlet.

The external appearance of the outlet fitting is determined by the water outlet and the adjacent outlet nozzle and its screw connection at the water outlet. In order to create an aesthetically pleasing appearance, it is necessary to make the visible surfaces of the outlet mouthpiece on the one hand and the outlet fitting in the region of its water outlet on the other hand as uniform as possible. Nevertheless, there remains a narrow gap between the outlet nozzle and the jet regulator insert, which tends to be soiled and can have a disturbing effect.

It has therefore also provided a likewise serving as Strahlbelüfter sanitary fitting with a multi-part installation housing, which has an external thread on its outer circumference for screwing into a provided on the inner circumference of the water outlet of a sanitary outlet fitting internal thread (see. DE 10 2005 010 551 A1 ). On the installation housing downstream of a flow straightener is formed, which is designed as a, flow holes having perforated plate, which forms the downstream housing end face. In the housing interior of the mounting housing a plurality of lattice-shaped inserts are used, which serve as Strahlreguliereinrichtung, which has to form the ventilated inside the housing individual rays back to a homogeneous, non-squirting overall jet. The downstream housing front edge has a profiling, which can serve as a tool engagement surface of the corresponding profiling of a further installation housing used as a turning tool. Since the out DE 10 2005 010 551 A1 previously known jet aerator can be screwed so deep into the water outlet of a sanitary outlet fitting that the downstream housing end face of the mounting housing does not project beyond the water outlet of the outlet fitting, the aesthetic impression is determined solely by the outlet fitting. To the installation housing at However, a further installation housing or another special turning tool is always required, which is not always available, especially in a household, water outlet of the outlet fitting or dismantling.

From the US-A-4,534,513 is therefore also a jet regulator with a sleeve-shaped installation housing previously known, which carries at its downstream housing circumference an external thread with which the installation housing can be screwed to an inner peripheral side provided at the water outlet of the outlet fitting internal thread. The installation housing has a downstream housing end face, which is formed by superimposed layers of metal screens and which is guided displaceably in the housing interior of the installation housing. By applying this coin to the downstream end of the housing, the housing end side is advanced into the interior of the housing such that a slot receiving the coin on the narrow side is uncovered, which serves as a tool engagement surface for the coin used as a turning tool. However, the displaceability of the housing end face has the consequence that the flow conditions inside the housing of the previously known jet regulator can change, so that the previously known jet regulator may not have consistent and in particular no consistently good beam quality and requires a large amount of installation space.

From the WO 2006/005099 A2 which represents the closest prior art, a flow restrictor is already known, with which the expiring through a water outlet of a sanitary outlet fitting amount of water can be throttled. The previously known flow rate limiter has for this purpose a housing which has an annular shoulder on the outer peripheral side on its inflow side. The housing can be used in a drainage nozzle which can be mounted on the water outlet until the annular shoulder engages on an inner peripheral side Ring heel rests in the outlet nozzle. In the housing of the known flow rate limiter a water jet splitting insert is screwed. In this case, the setting of the desired amount of water by changing the position of the insert in the housing and by screwing or unscrewing the insert by means of the screw on the housing. The insert has for this purpose a slot-shaped recess on its downstream end face into which a coin can be applied as a turning tool. At this downstream end face water outlet openings are provided, which are arranged in a circle around the slot-shaped recess at a distance to this and form the emerging water to a spray jet of isolated individual jets.

From the CH 380 042 A already known a jet regulator with a sleeve-shaped jet regulator housing, which carries on the inlet side on the outer circumference of the housing an external thread with which the jet regulator housing can be screwed into an internal thread in the water outlet of a sanitary outlet fitting. The previously known jet regulator offers the advantage that the notch provided on the outer circumference of the casing practically does not change the jet pattern of the outgoing water, but a screwdriver of the required width, which is required as a turning tool, is not always available.

From the US Pat. No. 3,520,481 A One already knows a ball joint having a screwed on the water outlet of an outlet fitting first hinge part and a downstream second hinge part. The joint parts are connected via a tubular connecting arm, which is rotatably mounted with a thickening designed as a ball head in a joint socket of the first joint part. At his Ball head opposite the free end of the tubular connecting arm is incorporated an internal thread into which a slot screw can be screwed for fixing the second hinge part on the connecting arm. Since a screwing of the first joint part of the sanitary outlet fitting by means of the slotted screw provided on the slot is not possible because the ball joint prevents transmission of the torque acting on the slot on the first joint part, the previously known ball joint for mounting on the outlet fitting on Outer circumference of the first joint part are detected.

Similar jet regulators, which have on their downstream housing face tool engagement surfaces for a simple turning tool, are also from the WO 2006/094680 A1 , of the US 2002/0084353 Alund the US-A-3,014,667A previously known.

Also, one has already created jet regulator with a jet regulator housing whose downstream housing end face has a spherical cap peripheral edge region which is pivotably mounted in a designed as a socket pan housing portion of the jet regulator housing that the exiting water jet aligned with respect to the impact point in the subsequent washbasin can be. In this case, a pin-shaped handle is provided on the downstream side of the housing end face, which protrudes disturbingly outwards and may possibly also cause undesired manipulation of the housing end face. If there is no visually visible feature on the outlet end face, it is not clear to the inexperienced or ignorant user that the water jet can be adjusted by actuating the outlet end face in its direction.

There is therefore a particular task, a sanitary To provide a functional unit of the type mentioned, which avoids the disadvantages of the prior art described above, and which is characterized by a much simplified handling.

The solution to this problem according to the invention consists in particular in that the at least one slot is formed as a groove, which has a groove base, which is designed to be liquid-permeable by a grid structure forming the groove bottom.

The functional unit according to the invention has at its downstream and the outflow openings having housing end face at least one downstream open slot, the opposite slot longitudinal sides are configured as a rotary control surfaces or as a tool engagement surfaces for a rotary tool, which can be releasably inserted into the at least one slot. The housing of the functional unit at the water outlet of the outlet fitting is rotatably supported such that, for example, between the housing outer circumference and the outlet end bounding the inner circumference of the outlet fitting provided screw or bayonet connection between a release and a holding position can be rotated. Since the at least one slot is formed as a groove, which has a groove bottom, which is designed to be permeable to liquid through a grid structure forming the groove bottom, the functional unit according to the invention is characterized by a high stability of the housing end face also in the region of the slot. The slot allows the use of the simplest turning tools that are usually at hand in a household. The slot is unobtrusively integrated into the housing end face, so that the slot causes less unauthorized or unwanted manipulation of the functional unit.

The functional unit according to the invention therefore always has at least one slot on its downstream housing end face, the opposite slot longitudinal sides of which serve as turning or tool engagement surfaces for a rotary tool which can be inserted into the slot.

In one embodiment of the subject invention, the housing of the functional unit is rotatably supported on the water outlet of the outlet fitting, so that the rotation force required to rotate the housing can be applied via the rotary tool inserted into the slot. A functional unit, which carries on its outer periphery an external thread which cooperates with an internal thread on the inner circumference of the water outlet, can thus be easily mounted or removed from the water outlet of the outlet fitting.

In another embodiment of the functional unit according to the invention, the housing end face is rotatably mounted relative to the housing. In such a functional unit, the rotary tool can be inserted into the slot to bring the housing end face in the desired relative position to the housing.

In a further embodiment according to the invention, which the two features of the subject invention described above combined, the rotary tool is inserted into the at least one slot to change the relative position between the housing end face and the housing. If this relative position can be fixed in at least one rotational position and / or in at least one direction of rotation, the housing itself can also be rotated in its relative position to the water outlet and, for example, mounted and dismounted there by a screwed or plugged / swivel connection.

As a turning tool, for example, a screwdriver can be inserted into the slot. A preferred development according to the invention, however, provides that the at least one slot is designed for inserting a coin-shaped rotary tool part region or a coin serving as a rotary tool. A coin-shaped rotary tool subarea or a coin which can be used as a rotary tool offer the advantage that the comparatively large flat sides of this rotary tool clearly recognize the relative position of the housing, housing end face and water outlet. In particular, a coin is available as a turning tool in the rule.

In order to be able to center the coin or the coin-shaped rotary tool subregion quickly and easily in the position of use in the slot, it is advantageous if the at least one slot has a circular segment-shaped cross section in the direction of insertion.

In order to be able to apply the rotary tool quickly to the housing end face, it is expedient if at least two intersecting slots are provided on the housing end face. In this case, a preferred embodiment according to the invention provides that the slots are arranged crosswise to each other are and that the junction of the intersecting slots is provided approximately centrally to the longitudinal extent of at least one slot.

Slot and turning tool can serve different purposes.

Thus, the housing end face may additionally be rotatably mounted thereon relative to the housing in order to adjust, for example, the adjusting elements located inside the housing or to be able to adjust and align the housing end face and the flow openings provided thereon relative to the housing longitudinal axis.

In addition to or instead of this alignment function of slot and turning tool these can also be intended for installation and / or disassembly of the functional unit in the water outlet of the sanitary outlet fitting. In this case, a further development according to the invention consists in that the rotary tool which can be inserted into the at least one slot for mounting and / or disassembling the functional unit which can be detachably mounted and / or dismounted by a plug / rotary or rotary movement at the outlet end of the outlet fitting is intended.

In order to change the relative position of the housing end face in relation to the housing, it is expedient if the housing end face in the downstream end plane of the functional unit rotatably guided about the housing longitudinal axis and / or oriented to any, transverse to the housing longitudinal axis Swivel axis is pivotally mounted.

In order to be able to attach the functional unit which can be inserted into the outlet fitting there easily by means of a simple screw connection, it is advantageous if an external thread is provided on the housing outer circumference of the housing interacts with an internal thread on the inner circumference of the outlet fitting, and that on the at least one slot, the torque required for screwing in and unscrewing the thread to the housing is transferable.

In order to give the housing end face in the region of the slot sufficient stability and to make the slot sufficiently deep, so that a turning tool firmly and securely attack it, it is advantageous if the housing end face at least in the region of at least one slot has a cross-sectional thickening.

In this case, it has no influence on the mounting elements located inside the housing if the housing end face has a convex or similar outwardly projecting shape, and if this shape is preferably centered on the end face center point.

The ease of use of the functional unit according to the invention is facilitated if the at least one slot has a slot longitudinal extent approximately radially aligned with the end face center.

If the outflow-side housing end face of the functional unit according to the invention is mounted rotatably and / or pivotably in the housing, the outgoing water jet can be changed in its outlet direction. In this case, a preferred embodiment according to the invention provides that at least one, preferably arranged on a running through the center of the housing end face center line spacer is provided on the inflow side of the housing end face, which is connected upstream of a hole, grid or Net structure or the like flow shaping part is applied and defines a pivot axis about which the housing end face in the selected relative position or rotational position of the housing and housing end face is tiltable or pivotable.

In this case, not only the relative position of the housing end face on the one hand and the housing on the other hand can be pivoted and / or rotated, but also the assembly or disassembly of the held by a screw or a plug / rotary connection in the water outlet housing is facilitated if on the outflow side of the Flow forming part projects at least one rotation stop, which abuts in at least one relative position or rotational position of the housing and housing end face on the at least one spacer, that the housing and the housing end face are rotatably connected.

To better recognize the pivot axis of the housing end face and to facilitate alignment of the exiting water jet, it is advantageous if at least one slot axially parallel or offset by 90 ° to the at least one, provided on the inflow side of the housing end face spacer is arranged.

Further developments according to the invention will become apparent from the claims and the description in conjunction with the figures. The invention will be described in more detail below with reference to preferred embodiments.

Fig. 24

one with the functional units in the Fig. 1 to 5 comparable functional unit, which is designed as a jet regulator, which carries at its jet regulator housing an external thread, wherein in the housing interior of the jet regulator housing, a plurality, a hole, grid or mesh structure and configured as insertion parts flow shaping parts are used.

In the Fig. 1 to 24 Different versions 1, 2, 3, 4, 5, 41 and 42 of a sanitary functional unit are shown. The functional units 1, 2, 3, 4, 5, 41 and 42 have a housing 6, which is releasably attachable to the water outlet 7 of a sanitary outlet fitting 8 (see. FIGS. 12 and 13 ). The housing 6 has a downstream housing end face 9, which has a plurality of outflow openings 10 Has. The outflow openings 10 are bounded by a honeycomb cell-like outlet structure, which forms at least a portion of the housing end faces 9.

The functional units 1, 2, 3, 4, 5, 41 and 42 are designed here as a jet regulator or have such. While in the functional units 1 and 2 according to the Fig. 1 to 5 between the outflow-side jet regulator 11 and an inflow-side attachment screen 12, a flow rate regulator 13 is interposed, which is to limit the water flowing through, regardless of the water pressure to a maximum flow volume per unit time, the functional units 3, 4, 5 and 42 according to Fig. 6 to 21 and Fig. 24 designed as a jet regulator, which is preceded only by a front screen 12 for filtering the possibly entrained in the water dirt particles. The in the Fig. 24 and jet regulator 41 illustrated does not require such an attachment screen.

With the jet regulators shown here, which are designed as ventilated jet regulators, the water emerging from the water outlet is to be shaped into a homogeneous, non-spraying and pearly-soft water jet. For this purpose, the jet regulators have an inflow-side jet breaker which divides the inflowing water into a plurality of individual jets; This creates a negative pressure on the outflow side of the jet separator, which causes an intake of ambient air, which penetrate through housing or ventilation openings 14 into the housing interior of the housing 6 and can be mixed there with the water flowing through.

The jet disintegrator can be designed, for example, as a perforated plate 15 or as a cup-shaped diffuser 16, on the pot peripheral wall of which flow openings 17 are provided and whose bottom of the pot is designed as a leading to the flow-through openings 17 baffle and deflection 18. Coming from the jet splitter and here enriched with ambient air individual jets are formed in a downstream flow rectifier again to a homogeneous emerging total beam, the housing end face 9 forms the flow straightener.

In the Fig. 1 to 24 It can be seen that at the downstream housing end face 9 of each functional unit 1, 2, 3, 4, 5, 41 and 42 at least one slot 19 is provided, the opposite slot longitudinal sides 20 as turning or tool engagement surfaces for a in the at least one Slot 19 releasably insertable rotary tool are configured. In Fig. 5 is indicated by a dotted line that in the at least one slot 19, a coin-shaped rotary tool portion or preferably serving as a rotary tool coin 21 is used.

The at least one slot 19 is here designed as a groove whose groove base provided on the side facing away from the slot opening is closed or, as here, for example, by a hole structure in the groove base, can be made liquid-permeable or open. In order to be able to align a coin 21 inserted therein into the slot 19, it is expedient that the at least one slot 19 forms a circular segment-shaped depression in the direction of insertion.

Slot 19 and rotary tool can serve various purposes.

So is in the in Fig. 7 to 23 shown functional units 3, 4, 5 and 41, the rotary tool for aligning the relative position between the housing end face 9 and the Housing 6 is provided by means of a rotating and / or pivoting movement.

Like from the FIGS. 7 to 23 can be seen, the housing end face 9 is rotatably guided approximately in the downstream end plane of the functional units 3, 4, 5 and 41 and mounted pivotable or tiltable about any, transverse to the housing longitudinal axis oriented pivot axis. The outer circumference 22 of the disk-shaped housing end face 9 is designed to spherical cap and pivotally held in a complementary shaped socket 23, which is formed by a portion of the housing inner peripheral wall of the housing 6. In this case, the pivot axis may be formed by spacers 43 which protrude on the inflow side of the housing end face 9 and which bear against a upstream flow forming part 44 such that these spacers 43 form a pivot axis about which the housing end face 9 tilted or pivoted can be.

By rotating, pivoting or pivoting and pivoting the housing end face 9 relative to the housing 6, the emerging water jet can be aligned with respect to the point of impact in the wash basin. The walls delimiting the outflow openings 10 are designed as flow guide walls 24, which preferably have a greater height than the clear diameter.

In addition to or instead of the above-mentioned alignment function can be used in the at least one slot 19 rotary tool for mounting and / or disassembly of the releasably mountable by a plug / rotary movement or a rotary motion at the outlet of the outlet fitting or dismountable functional unit. The functional units 1, 2, 3, 4, 41 and 42 have for this purpose on the housing outer periphery of its housing 6 on an external thread 25 which with an internal thread 26 (see. Fig. 12 ) cooperates on the inner circumference of the outlet fitting. About the at least one slot 19 for screwing in and unscrewing the threads 25, 26 required rotational force on the housing 6 is transferable.

While in the functional units 1, 2 and 42, the rotary tool and the slot 19 serve only one purpose, the slot 19 in the in the FIGS. 6 to 15 and 22 to 23 shown functional units 3, 4 and 41 both for aligning the downstream housing end face 9 as well as for mounting or dismounting of the housing 6 at the water outlet of the outlet fitting needed. Since in the functional units 3, 4 and 41, the housing end face 9 is rotatably or pivotally mounted in the housing 6 are rotatably connected to the upstream in the flow direction, connected to the housing 6 and as a grid, network or - as here - as a hole structure formed Flow shaping part 44 rotational stops 45 are provided, which cooperate in a rotational position of the housing end face 9 with the spacers 43. If the spacers 43 abut on these rotation stops 45, the applied rotational force is converted into a screwing-in or unscrewing movement of the screw connection provided between the housing outer circumference and the fitting inner circumference.

At the in Fig. 16 to 21 shown functional unit, only the outflow-side housing end face 9 is pivotally mounted in the housing 6 such that the outgoing water jet can be aligned with respect to the subsequent washbasin. In order to fix the functional unit 5 according to Figures 16 to 21 at the water outlet of a sanitary outlet fitting releasably, a per se usual, but not shown here outlet nozzle is required. The housing 6 of the functional unit 5 can be inserted into the sleeve-shaped outlet mouthpiece to subsequently releasably secure the outlet nozzle at the outlet end of the sanitary outlet fitting.

In order to make the housing end face 9 stable even in the region of the slot 19, it is advantageous if the housing end face has a cross-sectional thickening at least in the region of the at least one slot 19. In the FIGS. 1 to 24 It can be seen that the housing end face 9 here for this purpose has a convex, outwardly projecting shape, wherein this shape is centered to the end face center of the housing end face 9. Due to the convex shape, the slot 19 can extend comparatively deep into the housing end face 9, without the housing interior of the housing 6 remaining between the housing end face 9 and the jet splitter 15 being substantially restricted; This housing interior is therefore - as in Fig. 24 is illustrated - for other, for example, as a grid or reticulated or formed as a hole structure inserts available, which can be used as needed for beam regulation or beam shaping in the housing interior.

The slot 19 has a slot longitudinal extent approximately radially aligned with the end face center.

From a comparison of FIGS. 3 and 4 on the one hand and the FIGS. 15 . 17 . 21 and 24 On the other hand, it is clear that at least two, intersecting slots 19 may be provided on the housing end face 9. In the functional unit 1, the slots 19 are arranged crosswise to each other, wherein the crossing node of the intersecting slots 19 approximately centrally to the longitudinal extent of Slots 19 is provided.

In the FIGS. 1 to 24 are the functional units 1, 2, 3, 4, 5, 41 and 42 designed as a jet regulator or have such a jet regulator. It is also possible, the outflow-side housing end face of other functional units, which are designed for example exclusively as a flow regulator or flow restrictor, with a slot 19, which facilitates the handling and / or assembly / disassembly of these functional units.

In Fig. 1 it can be seen that the hole structure provided on the housing end face 9 outside the slot 19 is spaced from the slots such that the slot longitudinal sides 20 have a greater wall thickness compared to the flow guide walls 24.

In the Fig. 22 to 23 is clearly seen that on the upstream side of the housing end face two spaced-apart spacers 43 are provided, which are arranged on a running through the center of the housing end face 9 center line. These spacers 43 abut against the upstream of the flow direction and here formed as an insert part Strömungsformungsteil 44 such that the spacers 43 define a pivot axis about which the housing end face 9 in the selected relative position or rotational position of housing 6 and housing end face 9 tiltable or is pivotable. By turning the housing end face 9 in the joint socket 23 of the housing 6, the spacers 43 can be realigned so that the pivot axis formed by the spacers 43 also changes in its relative position to the housing 6. In the Fig. 22 to 23 It can be seen that 44 two rotational stops on the downstream side of the upstream flow forming part 44 Protrude 45, which rest in at least one relative position or rotational position of the housing 6 and the housing end face 9 on the spacers 43, that the housing 6 and the housing end face 9 are rotatably connected to - in addition, the corresponding functional unit 41 in the water outlet of to assemble or disassemble sanitary outlet fitting (cf. FIGS. 22 and 23 ).

The functional units 1, 2, 3, 4, 5, 41, and 42 shown here thus always have at least one slot 19 at their downstream housing end face 9, whose opposite slot longitudinal sides 20 serve as turning or tool engagement surfaces for a slot serve rotary tool. In the in the Fig. 1 to 5 and 24 As shown, the housing 6 of the functional unit 1, 2, 42 is rotatably supported at the water outlet of the outlet fitting, so that the rotational force required to rotate the housing can be applied via the rotary tool introduced into the slot 19. These functional units 1, 2 and 42, which carry on the outer circumference of their housing 6 an external thread 25 which cooperates with an internal thread on the inner circumference of the water outlet, can thus be easily mounted or disassembled at the water outlet of the outlet fitting.

In another embodiment, not shown here, the housing end face 9 is only rotatably supported relative to the housing 6. In such a functional unit, the rotary tool can be inserted into the slot 19 in order to bring the housing end face 9 into the desired relative position to the housing 6.

In the in the 6 to 23 shown embodiments, which combine the two features described above, the rotary tool in the at least one slot 19th used to change the relative position between the housing end face 9 and the housing 6. If the spacers 43 are in at least one rotational position on the rotation stops 45 in such a way that this relative position of the housing end face 9 and housing 6 is fixed, the housing 6 can also be rotated in its relative position to the water outlet. The functional units 3, 4, 5 and 41 can be mounted or dismounted by turning the housing 6 in the water outlet.
