Description

The invention relates to a sanitary fitting with a one- or multi-part installation housing, which has a thread for attachment to a provided at the water outlet of a sanitary outlet fitting mating thread, the housing has a downstream housing end face with flow holes and wherein in the housing at least one insert part up to a Insert stop is used.

Sanitary components are required as jet former, non-aerated jet regulator, jet aerator, flow regulator or non-return valve in various designs. For example, aerated jet regulators, so-called jet aerators, have been created to form a homogeneous, non-spattering and pearly-soft jet of water.

Out DE-GM 93 14 990 The Applicant is a jet aerator previously known, which has a perforated plate serving as a beam splitter in its installation housing, which has a number of flow holes for generating a plurality of individual jets. In the discharge area of the flow holes pins are provided, whose pointing to the perforated plate free and conically tapered pin end is designed as Abweisschräge, each deflects one of the flow holes coming from the individual jets 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 that can be screwed to 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 jet aerator serving as a sanitary fitting with a multipart installation housing that 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 installation housing a plurality of lattice-shaped insertion parts are used, which as Strahlreguliereinrichtung serve, which has the inside of the ventilated individual jets again to form 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. In order to mount or dismount the installation housing at the water outlet of the outlet fitting, but always another installation housing or other special turning tool is required, which is not always available, especially in a household.

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 in the housing interior of the previously known jet regulator can change, so that the previously known Jet regulator may not have consistent and in particular no consistent and in particular no consistently good beam quality and requires a lot of space.

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 CH-PS 380042 , of the US 2002/0084353 A1 , of the US 3,014,667 and the US 4534514 previously known.

There is therefore a particular object to provide a sanitary fitting of the type mentioned above, which is characterized by ease of use and yet represents an at least equivalent alternative to the mountable with an outlet mouthpieces with regard to function and aesthetic appearance of the outlet fitting.

An inventive proposal for solving this problem provides that the mounting part has a ventilated aerator or is configured as such that the peripheral wall of the housing at least in an at least double-walled configured portion bounds at least one ventilation duct, and that the at least one, the downstream end of the housing side open Venting channel opens into at least one, leading into the housing interior of the installation housing ventilation opening.

The built-in part according to the invention has a one- or multi-part installation housing, which has an external thread on its housing outer circumference, which is intended for screwing into a provided on the inner circumference of the water outlet of a sanitary outlet fitting internal thread. With the help of the installation housing provided external thread, the installation part according to the invention may optionally also screw so deep into the internal thread on the water outlet until the fitting does not or hardly protrudes beyond the water outlet. In this case, an outflow-side housing end face is provided on the installation housing, which has flow holes through which the water flowing through the fitting can flow. At least one insert part can be inserted into the installation housing up to an insertion stop, which insertion part has to shape and / or regulate the water flowing through.

According to the above proposed invention, it is provided that the built-in part has a ventilated jet regulator or is designed as such. The peripheral wall of the installation housing defines at least in an at least double-walled configured portion of at least one ventilation duct, which is open to the downstream housing end side and which opens into at least one, leading into the housing interior of the installation housing ventilation opening. Thus, ambient air can be sucked in through the ventilation channel which is open toward the downstream housing front side and introduced into the housing interior via the at least one ventilation opening, where this ambient air is mixed with the water, which may have been temporarily divided into individual jets, in order to produce a pearly-soft water flow. Since the at least one ventilation channel is integrated into the circumferential wall of the installation housing, the installation part according to the invention can be mounted with its external thread in such internal threads, which are also intended to receive an outlet nozzle. It can thus be used either on a conventional jet regulator, which requires an outlet nozzle for mounting, or it can instead be used according to the invention the built-in part, which is no longer dependent on an outlet nozzle. There the fitting according to the invention is no longer dependent on an outlet nozzle, and since such an outlet mouthpiece was usually made of brass and the manufacturing process had required a final chrome plating the brass part, the costs associated with the procurement of such material materials are avoided, regardless of the material supply Metal ensured and on a polluting chrome plating process can be dispensed with.

According to a further proposal according to the invention, is claimed for the self-protection, in addition or instead provided that the downstream housing front is convex or convex curved in the outflow direction and at least one slot, the opposite slot longitudinal sides as turning or tool engagement surfaces for an in the at least one slot releasably deployable rotary tool are configured.

In this proposed invention, the fitting according to the invention on its downstream housing end face on at least one slot, the opposite slot longitudinal sides are designed as a rotary control surfaces or tool engagement surfaces for a, in the at least one slot releasably deployable rotary tool. In this case, the downstream housing front side is formed in the outflow such convex or convex curved that the slot can be made sufficiently deep to provide the rotary tool on the corresponding deep slot longitudinal sides a sufficient turning or tool engagement surface, without thereby excessively large space in the housing interior get lost.

In order to be able to form the water jet emerging from the built-in part well, without therefore the downstream housing front side offers a high flow resistance, it is expedient if the downstream housing front side is designed as a grid, mesh or hole structure.

The at least one slot can be designed as a slot-shaped opening of the housing end face. A preferred embodiment according to the invention, in contrast, provides that the at least one slot has a slot or groove bottom, which is closed or - for example, by a slot or groove bottom forming hole or grid structure - open or liquid-permeable designed.

In order to design the slot longitudinal sides serving as turning or tool engagement surfaces sufficiently stable, and to be able to transmit a correspondingly high torque to these slot longitudinal sides, it is advantageous if the housing end face has a cross-sectional thickening at least in the area of the at least one slot.
It is particularly advantageous if the slot longitudinal sides have a greater wall thickness than the flow guide walls forming the grid, mesh or hole structure of the housing end face.

A further proposal according to the invention of its own worth-worthy significance provides that the installation housing has a downstream housing section with a reduced compared to the adjacent inflow housing section housing cross-section, and that the free end edge of the above the water outlet projecting downstream housing portion serves as a drip edge.

A designed according to this invention proposal sanitary fitting has a downstream housing portion, the one opposite the adjacent inflow-side housing portion has reduced housing cross-section. In this case, the free end edge of the over the water outlet projecting outflow-side housing portion is designed as a drip edge at which the remaining water can still drain after closing the stopcock without overflowing on the outside of the outlet fitting and run along there.

In order to be able to uniformly mix ambient water with the water flowing through the installation component according to the invention over its entire cross section, it is advantageous if a plurality of ventilation openings, preferably uniformly distributed over the housing circumference, are provided.

In order to accommodate the at least one ventilation channel with little effort in the peripheral wall of the installation housing, it is advantageous if the housing has at least in a downstream housing portion an outer, at least a portion of the external thread bearing housing wall and a spaced by the at least one ventilation duct inner housing wall.

In this case, the inner housing wall can also be configured as a drip edge when the inner housing wall projects beyond the outer housing wall and forms the downstream housing front edge.

In order to screw the insert according to the invention well with a corresponding rotary tool on the inside of an outlet fitting provided inside circumference female thread, it is advantageous if the inner and the outer housing are preferably connected to each other via radial webs and if at least two webs as a rotary or Tool engagement surfaces are provided for an insertable into the space between the webs rotary tool.

If the built-in component according to the invention is designed as a jet aerator, the ambient air can be sucked into the housing interior of the installation housing by a negative pressure. A preferred embodiment according to the invention provides that the jet regulator has an insert part designed as a jet splitter, which divides the water flow into a plurality of individual jets and that the at least one ventilation opening is arranged in a section of the housing interior which follows the jet splitter in the direction of flow. Since the inflowing water stream is divided into a plurality of individual jets in the jet splitter and since these individual jets experience an increase in speed in the area of the cross-sectional constriction caused by the jet splitter, a negative pressure is generated according to the Bernoulli equation on the downstream side of the jet crusher, the suction of the ambient air in the Housing interior causes.

In order for the highest possible negative pressure on the outflow side of the jet breaker arises and thus the water flowing through the insert according to the invention can be well and effectively mixed with the ambient air, it is advantageous if the jet splitter for splitting the water flow in a plurality of individual jets, a plurality of flow openings Has.

It is possible that the jet splitter is designed as a perforated plate or as a diffuser. However, a preferred embodiment according to the invention provides that the diffuser designed as a jet separator has a flow-bearing ring wall bearing, on the downstream side a central baffle is formed, which the inflowing Water flow deflects towards the peripheral Dürchflussöffnungen.

It is expedient if a diffuser ring is provided, which surrounds the diffuser at least in the region of the flow openings and if a flow channel tapering in the direction of flow is provided between the inner circumference of the diffuser ring and the outer circumference of the diffuser. The water divided into individual jets in the region of the diffuser is accelerated in the flow channel provided between the diffuser and the diffuser ring in such a way that a comparatively high negative pressure can already be generated in the region of this flow channel with small amounts of water.

So that the homogeneous jet pattern of the exiting water jet is not impaired, it is advantageous for the diffuser ring to shield the at least one ventilation opening at a distance such that the adjacent subarea of the diffuser ring serves as splash guard for the at least one ventilation opening against the water flowing on the inside circumference of the diffuser ring.

In order to allow the ambient air to flow in in particular in the adjoining directly to the jet splitter without the water there penetrate through the ventilation holes in the ventilation channel and can escape from there into an area outside the jet zone, it is expedient if the diffuser ring at least one Has Luftdurchströmöffnung and when the at least one air flow opening narrows in the flow direction preferably to a Luftdurchströmschlitz.

Place the insert housing and the diffuser ring as well as the diffuser ring and the diffuser exactly in relation to each other and to be able to mount, it is expedient if in the insertion of the diffuser ring and / or in the diffuser ring, the diffuser can be used up to an insertion stop.

So that the individual parts of the installation part according to the invention can not inadvertently separate from each other during transport or storage, it is advantageous if the diffuser ring in the insertion and / or the diffuser in the diffuser ring is releasably fixable and preferably releasably latched. In this case, a preferred embodiment according to the invention provides that an annular shoulder or annular flange is provided on the diffuser ring and / or on the diffuser, which cooperates with the insertion stop.

Thus, the water flowing through pressure can be regulated independently of pressure to a maximum water volume per unit time, it is advantageous if the mounting part has a flow rate regulator, which is connected upstream of the aerated jet regulator in the flow direction.

In order that the dirt particles entrained in the water do not lead to functional impairments in the successive functional units of the built-in component according to the invention, it is expedient for the preferably aerated jet regulator and, if appropriate, the flow rate regulator to be preceded by a front screen in the flow direction.

In order to avoid leakage currents on the outer circumference of the installation housing over, it is advantageous if an annular seal made of preferably soft elastic material is provided for axial sealing between the mounting part and an annular outlet located in the water outlet.

Further features of the invention will become apparent from the following description of inventive embodiments in conjunction with the claims and the drawings. The individual features may be implemented individually or in combination in an embodiment according to the invention.

In the FIGS. 1 to 12 and 14 to 27 is a sanitary fitting in various versions 1, 2, 4, 5, 6 and 7 shown. The built-in parts 1, 2, 4, 5, 6 shown here and 7 are mounted on the water outlet 70 of a sanitary outlet fitting 8 not shown here otherwise. The mounting parts 1, 2, 4, 5, 6 and 7 have a mounting housing 9, which has an external thread 10 at its outer circumference. The external thread 10 is intended for screwing into an internal thread 11, which is provided on the inner circumference of the water outlet 70 of the sanitary outlet fitting 8 (see. Fig. 14 ). The installation housing 9 has a downstream housing end 12 with flow holes 13.

The circumferential wall of the installation housing 9 of the installation parts 1, 2, 4, 5, 6 and 7 shown here defines an annular peripheral ventilation duct 14 in a double-walled partial area. This ventilation duct 14, which is open towards the downstream, in the figures lower housing end side 12, opens into a plurality of ventilation openings 15, which are arranged distributed uniformly over the housing circumference and lead into the housing interior of the installation housing - 9. The ventilation channel 14 and the ventilation openings 15 are part of a built-in parts 1, 2, 4, 5 and 6 jet regulator 16, a so-called Strahlbelüfters. In contrast, the installation element 7 itself is designed as a jet regulator.

The installation housing 9 of the mounting parts 1, 2, 4, 5, 6 and 7 has in its downstream housing portion an outer housing wall 17 and a spaced apart by the ventilation channel 14 inner housing wall 18, of which the inner housing wall 18 projects beyond the outer housing wall 17 and forms the downstream housing end edge. The outer housing wall 17 carries at least a portion of the external thread 10. The inner and the outer housing 17, 18 are connected to each other via radial webs 19, wherein the webs 19 as a turning or tool engagement surface for an insertable into the space between the webs 19 rotary tool are provided.

Since such a special turning tool but especially in a private household is not always available, the downstream housing end face 12 of the in the FIGS. 15 to 27 shown mounting parts 5, 6 and 7 at least one slot 20, 21, the opposite slot longitudinal sides are designed as a turning or tool engagement surfaces for a rotary tool, which is releasably insertable into the at least one slot 20 and 21 respectively. As a turning tool, a screwdriver, but preferably also serve a coin. So that with the help of the insertable into the slot 20, 21 rotary tool and a higher torque can be transmitted, the downstream housing end 12 in the outflow convex or convex, so that the slot longitudinal sides are preferably designed deep without the housing end face 12 in the Housing interior space would significantly limit available space. Thus, there is sufficient space in the housing interior to provide further insertion or flow forming grooves 47, 48 therein (see FIG. Fig. 27 ). While the jet regulator 5 according to the FIGS. 15 to 20 only carries an approximately radially oriented slot 20 on its housing end face are on the housing end face 12 of the in the FIGS. 21 to 26 shown mounting parts 6 two radially oriented and arranged at right angles to each other slots 20, 21 are provided, which form a cross slot here.

In the installation housing 9 of the mounting parts 1, 2, 4, 5, 6 and 7, at least one insert part can be used up to an insertion stop. So will the FIGS. 1 to 12 and 14 to 26 clearly that in the installation housing 9 of the mounting parts 1, 2, 4, 5, 6 and 7 designed as a beam splitter insert can be used, which has to divide the water flow into a plurality of individual jets and to a plurality of flow openings 22 has. The serving as a beam splitter insert is here designed as a diffuser 23, which has a flow opening 22 bearing ring wall 24. To the annular wall 24 of the cup-shaped diffuser 23 here, a central baffle 25 is formed, which deflects the inflowing water flow in the direction of the peripheral flow openings 22.

The diffuser 23 is encompassed by a diffuser ring 26 such that between the inner circumference of the diffuser ring 26 and the outer circumference of the diffuser 23, a flow channel 30 tapering in the direction of flow is provided. The ventilation openings 15 are covered by the diffuser ring 26 at a distance such that the adjacent portion of the diffuser ring 26 serves as a splash guard 27 for the ventilation openings 15 against the water flowing on the inner circumference of the diffuser ring 26.

The diffuser ring 26 of the built-in parts 2, 5 and 6 has air flow openings 29, which narrow in the flow direction to an air flow slot. The ambient air can thus be sucked through the ventilation duct 14 through the ventilation openings 15 in the peripheral wall and the Luftdurchströmöffnungen 29 in the diffuser ring 26 into the housing interior of the mounting housing 9 to mix there with the individual beams generated by the diffuser 23 before they again at the serving as a flow straightener housing end face 12 to be united and formed into a homogeneous, non-squirting and bead soft vented overall jet.

The integrated into the built-in parts 1, 2, 4, 5 and 6 jet regulator 16 thus consists essentially of the diffuser 23, the associated diffuser ring 26, and designed as a flow rectifier housing end face 12 of the installation housing. 9

While in the built-in parts 1, 2, 4, 5 and 6 of the jet decomposer is designed as a diffuser 23, which is designed as a jet regulator built-in part 7 in FIG. 27 Instead, a beam splitter, which is designed as a perforated plate 40, which has a corresponding number of axial flow holes 41 for dividing the inflowing water into a plurality of individual jets.

In order to suck the ambient air into the housing interior and to be able to generate a negative pressure in the housing interior, an annular flow passage 30 tapering in the direction of flow is provided between the inner circumference of the diffuser ring 26 and the outer circumference of the diffuser 23. In this tapered flow channel 30, the separated individual streams in the diffuser 23 are accelerated such that on the downstream side of the diffuser 23 in the region of the downstream channel opening of the flow channel 30, a negative pressure.

Also at the in FIG. 27 the built-in part 7, the passage cross-section in the flow holes 41 of the perforated plate 40 is narrowed such that the individual beams generated by the perforated plate 40 are accelerated so that even on the downstream side of the perforated plate 40, a negative pressure.

While the diffuser ring 26 can be inserted into the installation housing 9 up to an insertion stop 31, the diffuser 23 in turn can be inserted into the diffuser ring 26 up to an insertion stop 32. In this case, a sealing ring 33 is preferably made of soft elastic material, which seals the separating gaps between the housing 9 and the housing 26 and diffuser between diffuser 26 and diffuser 23 and the axial sealing between the inflow-side end edge of the mounting housing 9 and an annular shoulder in the water outlet 7 of the sanitary outlet fitting. 8 can be clamped.

In the Fig. 1 to 12 and 14 to 26 It can be seen that the flow regulator of the built-in parts 1, 2, 4, 5 and 6, a flow rate controller 34 is connected upstream, which has an annular throttle body 35 made of elastic material, which throttle body 35 between itself and a Regelprofilierung 36 under the pressure of the flowing water changed control gap 37 limited. This flow rate regulator 34 is connected via a latching connection with the jet regulator 16 following in the flow direction and in particular with its diffuser 23. The flow rate regulator 34, in turn, is preceded by an attachment screen 38, which conically tapers counter to the flow direction, and has to filter out the dirt particles entrained in the water before these dirt particles can impair the function of the flow rate regulator 34 or the downstream jet regulator. A comparable attachment screen 38 is also provided in front of the installation part 7.
