Abstract

The sanitary fitting (1) has a housing (6) with a spray regulator (4), fitted with at least one insert (5a,5b) with lateral bars across the water flow to define passage openings (12) between them. The bars of the insert(s) form a grid or a net, with intersection points (10). The water flow to the spray regulator is passed through a perforated plate (2) to give water sprays.

Description

The invention relates to a sanitary fixture which has a Strahlreguliereinrichtung inside a built-in housing, which Strahlreguliereinrichtung at least one insertable in the installation housing insert part, which has transversely oriented to the flow direction webs, which define between them through openings.

From the DE 100 27 987 A1 A jet regulator with a jet regulator housing is already known, in the interior of which a jet regulating device is provided which has a plurality of insertion parts which can be successively inserted into the jet regulator housing in the flow direction. These inserts each have an outer support ring, which is connected on the inside with approximately parallel extending, spaced-apart webs. The webs bound respectively via the passage cross-section extending, unidirectionally limited passage openings, wherein the passage openings of adjacent insertion parts are arranged offset in the circumferential direction of the mounting housing to each other. With the help of the provided in the prior art jet regulator inserts complex, the flow rate sharply slowing down and a pearlescent-soft water jet forming mesh-like or cascade-shaped structures are formed, wherein the producible with little effort by means of conventional manufacturing techniques insert parts are not prone to undesirable calcification. In order to achieve an effective speed reduction of the incoming water, it is advisable to arrange the webs of each insert with the smallest possible distance from each other. However, if this distance between the webs of an insert part is dimensioned too small, there is a risk that the dirt particles flowing in the line network do not slip between the webs and therefore can increasingly impair the function of the previously known jet regulator.

There is therefore in particular the task of creating a cost-producible and functionally reliable sanitary fitting of the type mentioned, which allows the best possible Strahlreguliereigenschaften even on a relatively small cross-sectional area.

The achievement of this object of the invention consists in the sanitary fitting of the type mentioned in particular in the features of the current patent claim. 1

The built-in part according to the invention has a Strahlreguliereinrichtung inside its built-in housing, which has at least one insertable in the built-in housing insert. This at least one insert part has webs which are oriented transversely to the throughflow direction and which are arranged in the manner of a lattice or net, according to the invention, crossing at intersection nodes. As a result of this grid-like or net-like structure, the at least one insertion part can also have a multiplicity of webs on a comparatively small cross-sectional area, which divide the inflowing water flow into a plurality of individual beams. Thus, even at high flow rates Effective mixing and jet control can be achieved on a comparatively small cross-sectional area with low production costs. Even with a large number of webs, these can be arranged in a lattice-like or net-like manner relative to one another in such a way that the passage openings are nevertheless sufficiently large to allow dirt particles entrained in the liquid flow to pass through.

The built-in part according to the invention is designed as a jet regulator in a preferred embodiment. A development according to the invention therefore provides that the Strahlreguliereinrichtung upstream of a Strahlzerlegeeinrichtung for decomposing the incoming liquid stream is arranged in a plurality of individual jets and that at least one insertion of the Strahlreguliereinrichtung is arranged relative to the jet disintegrating means so that the individual jets on crossing nodes of the at least one insertion part incident. A deceleration of the inflowing liquid and a division of the individual jets flowing into the jet regulating device can be achieved particularly effectively if the individual jets strike crossing nodes of the at least one insertion part.

The jet disintegrating device of the built-in part according to the invention can be designed, for example, as a baffle plate. Excessive noise is avoided, however, when the jet disintegrating device is designed as a perforated plate.

In order to increase the distribution of the individual beams even further and to further improve the beam control properties even on a small cross-sectional area, it is advantageous if at least two adjacent insert parts grid or web-like webs are provided. These insert parts also have webs crossing at intersection nodes, which divide the inflowing water flow into a multiplicity of individual beams. At the intersection of the Einsetzteile each water jet is again so effectively divided into several individual beams that even at high flow rates on a relatively small cross-sectional area an effective mixing and beam control can be achieved. The built-in component according to the invention is therefore distinguished by the best possible beam regulation properties even on the smallest cross-sectional area.

An embodiment according to the invention provides that the webs and the intersection nodes of the at least two adjacent insertion parts are aligned with each other. A particular advantage of such an embodiment is that at least two insertion parts can be identical.

In another refinement embodiment according to the invention, which is distinguished by a particularly effective division of the water jets in the smallest space, it is provided that the passage openings of an insert part are followed by the crossing nodes of the adjacent insert part in the flow direction.

A simple and producible with little effort embodiment according to the invention provides that at least one inflow and / or a downstream Einsetzteil is configured lattice-shaped and has two, intersecting shares parallel lattice webs. Additionally or alternatively, an inflow and / or outflow side insert may have a family of radial lands extending concentrically and annularly around the intersection with a family of coulters Cross bars. According to a further proposal according to the invention it is provided that at least one inflow and / or outflow-side insert part has star-shaped or web-like intersecting webs.

A space-saving embodiment of the installation part according to the invention, which also saves space in the axial direction, provides that the webs of at least one insertion part are arranged in a plane oriented preferably transverse to the direction of flow and the insertion parts are in particular plate-shaped.

In order to unify the single jet generated in the Strahlreguliereinrichtung back to a homogeneous, non-squirting total jet, it is advantageous if the Strahlreguliereinrichtung downstream of a flow rectifier having passage openings whose opening width is smaller than the height in the flow direction. It is particularly expedient if the flow rectifier is arranged at the outlet end of the built-in housing.

The flow straightener can be integrally connected to the built-in housing or used as a separate insert in the built-in housing. While a flow rectifier which can be used as a separate insert part in the built-in housing additionally supports the modular construction of the built-in component according to the invention, a flow rectifier connected in one piece with the built-in housing can also serve as a downstream vandalism protection of the built-in part.

The flow rectifier of the built-in part according to the invention can be adapted in its design to the application and the purpose. For example, it is provided that the flow rectifier rectangular, circular segment-shaped or has honeycomb passage openings.

It is also possible that the flow rectifier and / or the Strahlreguliereinrichtung have at least one metal mesh.

The built-in part according to the invention is designed as a jet regulator in a preferred embodiment.

In a built-in as a jet regulator built-in training provides according to the invention of its own worthy importance that the built-in housing is divided into at least two housing parts, that the housing parts are connected to each other and that an inflow-side housing part with the jet disintegrating device is firmly and permanently connected.

In this embodiment, the built-in housing is divided into at least two housing parts and thus at least in an inflow-side and a downstream housing part. Of these housing parts an inflow-side housing part is firmly and permanently connected to the jet disintegrating device. Since even a comparatively sensitive jet disintegrating device is securely, firmly and securely connected to the housing part at its peripheral edge, no significant functionally impairing deformation of the jet disintegrating device is to be expected, even under hot water temperatures and high water pressures. Since the jet disintegrating device is held firmly and permanently on the inner wall of the housing and since there is no longer required an annular flange as a support for the jet disintegrating device, the jet regulator can be designed with a relatively small housing diameter even at high flow rates, as in the prior art only at Beam regulators with lower Flow rate was possible. By firmly connected to the built-in housing jet disassembling the installation housing undergoes a radial reinforcement, which makes the sleeve-shaped mounting housing also a total of fracture and dimensionally stable. While in prior art beam regulators, in which a separate perforated plate was mounted as jet disintegrating device in the outer housing, always sealing problems between perforated plate and sleeve-shaped outer housing occurred, the jet regulator according to the invention has the significant advantage that these sealing problems do not arise due to the one-piece between Strahlzerlegeeinrichtung and zuströmseitigem housing part. Since the built-in housing consists of at least two mutually connectable housing parts, yet the Strahlzerlegeeinrichtung downstream in the flow direction Strahlreguliereinrichtung and optionally other required functional units can be used in the built-in housing. The built-in part according to the invention designed as a jet regulator is therefore characterized by a high dimensional stability and at the same time low production costs.

If a strong or less strong deceleration of the water flow in the installation part according to the invention is desired, an adaptation of the built-in part by replacing the Strahlreguliereinrichtung and its downstream functional units is possible. A preferred embodiment according to the invention therefore provides that at least two, optionally be inserted into the built-in housing Strahlreguliereinrichtungen are assigned to the existing of at least two interconnectable housing parts built-in housing.

The inflow-side housing part designed as a jet regulator built-in can be produced with little effort as a one-piece plastic injection molded part, if the jet disassembling device is integrally connected to the housing part assigned to it.

The expense associated with the manufacture of the mounting part is additionally reduced if the built-in housing has two housing parts which can be connected to one another in a parting plane oriented transverse to the inflow direction.

The housing parts of the mounting part according to the invention can be particularly easily and conveniently connected to each other when these housing parts of the built-in housing are releasably locked together. Instead, it is also possible to firmly connect at least two housing parts, for example by an adhesive or welded connection.

A preferred embodiment according to the invention provides that a downstream housing part is designed sleeve-shaped and that in this housing part at least one insert part of the Strahlreguliereinrichtung is used. It is advantageous if the at least one insert part can be inserted into the housing part assigned to the jet regulating device from its inflow side up to a plug-in stop or a support.

In order to be able to easily adapt the built-in component according to the invention to the different requirements even when using the same built-in housing, this built-in housing can be assigned a plurality of jet regulator devices that can optionally be inserted into the built-in housing. In addition or instead, it is possible that the Strahlreguliereinrichtung of the jet regulator is modular and it is associated with a plurality of selectively combinable with each other insert parts.

A preferred embodiment according to the invention sees that the outlet-side housing part at least in the region of the water outlet opening has a soft and / or water-repellent surface. The advantage of this embodiment is the absence of calcification in the region of its water outlet opening. In addition, in particular a soft surface can be easily cleaned by manually stripping any deposits.

For the same reasons, it may be advantageous if, in addition or instead, the outlet-side housing part is made of an elastic material at least in the region of the water outlet opening. It is preferable to use rubber, silicone, thermoplastic elastomers or other rubber-elastic materials.

In order to favor the ease of manufacture of the jet regulator according to the invention also in the region of its outlet-side housing part, it is advantageous if the outlet-side housing part is made essentially of an elastic material and / or a material with a soft or water-repellent surface.

Thus, a housing part made of rubber-elastic material is sufficiently stable in itself and can be secured for example by a latching connection to the adjacent housing part, it is advantageous if the outlet-side housing part is stiffened by circumferentially preferably evenly distributed longitudinal webs.

In this case, a preferred embodiment according to the invention provides that the longitudinal webs are provided at least in the region of the outlet opening.

A particularly advantageous embodiment according to the invention of its own worthy of protection provides that the outlet-side housing part in the region of the water outlet opening has at least one constriction or the like narrowing of its flow cross-section. This constriction or the like constriction of the flow cross-section has a calibrating effect on the outflowing water jet and its jet pattern. The constriction of the flow cross-section is provided in the region of the water outlet opening and thus in a region downstream of possible interference contours in the flow direction. By calibrating the water jet, a homogeneous and non-squirting spray pattern is significantly favored.

In order to simplify the production of the jet regulator according to the invention even further, it is advantageous if the outlet-side housing part is preferably connectable to the housing part adjacent to the inflow side via an in particular circumferential detent connection.

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.

Fig. 15

a jet regulator, similar to that FIG. 1 whose jet decomposing device is designed here as a baffle plate.

In FIG. 1 a sanitary fitting is shown, which is insertable into the outlet mouthpiece of a sanitary outlet fitting. The insert is here designed as a jet regulator 1, which serves to produce a homogeneous, pearly soft and non-squirting water jet. For this purpose, the jet regulator 1 has a jet disintegrating device 2, which may be formed, for example, as a baffle plate, but preferably-as here-designed as a perforated plate and divides the inflowing water flow into a plurality of individual jets. For this purpose, the perforated plate 2 has a corresponding number of flow holes 3, which preferably taper conically in the flow direction, at least on an inflow-side hole section. So that dirt particles can not penetrate into the mounting part 1 and there can lead to malfunctions, a front screen 17 is provided on the inflow side.

The jet decomposing device formed by the perforated plate 2 is followed by a jet regulating device 4 in the flow direction. This jet regulating device 4 is intended to strongly decelerate the individual jets coming from the jet disintegrating device 2, divide it into further individual jets and, if necessary, favor an air mixing in order ultimately to achieve a sparkling-soft water jet. The Strahlreguliereinrichtung 4 has for this purpose two insertion parts 5a, 5b, which at a distance from each other in the built-in housing 6 are used.

In FIG. 1 It can be seen that the built-in housing 6 is designed in two parts and two detachably latched together housing parts 7, 8 has. In this case, the inflow-side housing part 7 with the perforated plate 2 in one piece and thus both fixed and inextricably connected. These housing parts 7, 8 are detachably connected to one another in a parting plane oriented transversely to the inflow direction. Since a relatively thin perforated plate 2 is securely and firmly connected to the housing part 7 at its peripheral edge, no significant functionally impairing deformation of the perforated plate 2 is to be expected, even with hot water temperatures and high water pressures. Since the perforated plate 2 is held firmly and permanently on the inner wall of the housing and since there is no need for an annular flange as a support for the perforated plate, the jet regulator 1 can be designed with a relatively small housing diameter even at high flow rates, as in the prior art only was possible with beam regulators with low flow rate. Through the fixedly connected to the built-in housing 6 perforated plate 2, the built-in housing 6 undergoes a radial reinforcement, which makes the sleeve-shaped mounting housing 6 also a total breakage and dimensionally stable. Since the built-in housing consists of at least two detachably connectable to each other housing parts 7, 8, nevertheless the perforated plate 2 downstream in the flow direction Strahlreguliereinrichtung 4 and optionally other required functional units are inserted into the mounting housing 6. The jet regulator 1 is therefore characterized by a high dimensional stability and at the same time low production costs. The jet regulator 1 can be designed with a comparatively small housing diameter even at high flow rates. If different flow rates a corresponding adjustment of the jet regulator 1, this is possible by replacing the perforated plate 2 downstream Strahlreguliereinrichtungen and the like functional units.

In FIG. 1 can be seen that the downstream housing part 8 is designed sleeve-shaped and that in this housing part 8, the insertion parts 5a, 5b of the Strahlreguliereinrichtung 4 can be used up to a plug-in stopper 9. From a comparison of FIGS. 2 to 8 and in particular from the FIGS. 4 and 8th It is clear that the insertion parts 5a, 5b each have at crossing nodes 10 crossing webs 11, wherein the passage openings 12 of one of these inserts the junction nodes 10 of the adjacent insert part 5b are downstream in the flow direction, while the passage openings 12 of the outflow side insert part 5b, the crossing nodes 10th the adjacent inflow-side insertion part 5a are connected upstream in the flow direction.

The water jet flowing to the installation part 1 designed as a jet regulator is split into a plurality of individual jets at each crossing node 10 of the inflow-side insertion part 5a. These individual jets are again divided into a plurality of further individual jets at the junction node 10 of the downstream part 5b. The Strahlreguliereinrichtung 4 of the jet regulator 1 is characterized by the cascaded junction points 10 of their insertion parts 5a, 5b by a particularly effective deceleration of the incoming water jet even on the smallest cross-sectional area.

The Strahlreguliereinrichtung 4 of the jet regulator 1 shown here is modular; the Strahlreguliereinrichtung 4 are assigned a plurality of optionally combinable with each other insert parts 5. So have the in the Figures 2 and 3 illustrated insertion parts 5a and 5b grid-shaped webs 11. The lattice structures of these insertion parts 5a, 5b are arranged offset from one another by approximately 45 °, with the insertion part 5b shown in FIG. 3 in comparison to the insertion part 5a FIG. 2 has a smaller grid spacing. By Lageorientierungsein- or -ausformungen 13 at the outer peripheral edge of the insertion parts 5a, 5b, which cooperate with longitudinally oriented, complementarily shaped Lageorientierungsaus- or -einformungen on the housing inner circumference of the housing part 8, is always a positional arrangement of the insertion 5 to each other in the mounting housing. 6 guaranteed.

While that in FIG. 5 shown inflow-side insertion part 5c has a bevy of radial webs 11 ', which intersect at the intersection node with a crowd concentric and annular circumferential ridges 11 ", has the in FIG. 6 shown outflow-side insert part 5d star-shaped or web-like intersecting webs 11. The webs 11 of each plate-shaped designed insertion part 5 are arranged in a direction transverse to the flow direction plane.

In FIG. 1 can be seen that the Strahlreguliereinrichtung 4 at the outlet end of the mounting housing 6, a flow rectifier 14 is connected downstream. From a comparison of Figures 9 and 10 It is clear that this flow rectifier 14, in which the opening width of the passage openings 15 is smaller than the height in the flow direction, for example, honeycomb ( Fig. 9 ) or circular segment ( Fig. 10 ) Passage openings 15 may have.

In the Figures 11 and 12 are shown here serving as a flow straightener inserts having a grid-shaped metal mesh.

In FIG. 13 it is shown that the Strahlreguliereinrichtung 4 can also have two adjacent insertion parts 5a, 5b, the webs 11 and crossing nodes 10 are aligned with each other. It will be off FIG. 13 clearly that the insertion parts 5a, 5b of such a Strahlreguliereinrichtung 4 can also be configured identical, whereby the manufacturing cost can be further reduced. Just like in the FIGS. 4 and 8th , is also in FIG. 13 indicated by circles executed in bold that the flow openings of the perforated plate 2 with the crossing nodes 10 at least one, downstream in the flow direction insert part. By the in FIG. 13 in bold circles, the impact point of the individual beams coming from the jet disintegrating device 2 is illustrated at the crossing node 10 of the insertion part 5a.

In FIG. 14 is a, located in an outlet mouthpiece 21 jet regulator 1 is shown, the sleeve-shaped outer housing consists of two releasably latched together housing parts 7, 8. In this case, the inflow-side housing part 7 with the perforated plate 2 in one piece and thus both fixed and inextricably connected. While the upstream-side housing part 7 is made of a comparatively strong plastic material, the outlet-side housing part 8 is made of an elastic material and has a soft and water-repellent surface. Since the housing part 8 thus also in the region of its water outlet opening and thus in the region of the flow rectifier 14 provided there has a water-repellent surface, which is characterized in FIG. 14 illustrated jet controller 1 by the calcification of the outlet side flow rectifier 14. Since the outlet-side housing part 8 is made of rubber, silicone or a thermoplastic elastomer and thus has an elastic and soft surface, in particular on Flow rectifier 14 accumulated calcifications or dirt particles are easily detached manually. In order to additionally facilitate the manual cleaning of the jet regulator 1, it can be advantageous if the jet regulator 1 protrudes at least slightly beyond the outlet mouthpiece 21 with an outlet-side partial region.

How out FIG. 14 becomes clear, the inflow-side housing part 7 and the outlet-side housing part 8 are releasably held together by a latching connection. In order to prevent that the outlet-side housing part 8 can be pulled off axially from the inflow-side housing part 7, the support shoulders, on which both housing parts 7, 8 touch, are designed so that sufficiently large forces can be absorbed. In addition, the outlet-side housing part 8 is stiffened by radial longitudinal webs 22, which are arranged distributed uniformly in the region of the flow rectifier 14 and thus in the region of the outlet opening in the circumferential direction. By provided on the rubber-elastic housing part 8 longitudinal webs 22, which create very close to the inner contour of the outlet nozzle 21, it is prevented that the rubber-elastic housing part 8 expand and thus can be deducted from the housing part 7. In any case, the axial forces resulting from the water pressure on the elastic housing part 8 are comparatively small, since the water pressure at the perforated plate serving as jet disintegrating device 2 in the housing part 7 is already almost completely reduced.

In FIG. 14 can be seen that the outlet-side housing part 8 in the region of the water outlet opening has a constriction 23, which causes a constriction of the flow cross-section. Through this narrowing of the flow cross-section, a calibration of the outflowing water jet and a homogenization of the jet pattern is achieved.

The constriction 23 is provided in the region of the water outlet opening and thus in a region downstream of possible interference contours in the flow direction. By calibrating the water jet, a homogeneous and non-squirting spray pattern is significantly favored.

In FIG. 15 is one with FIG. 1 comparable jet regulator 1 shown. While in FIG. 1 has shown a perforated plate as jet disintegrating device 2, the jet disintegrating device 2 of the in FIG. 15 illustrated jet regulator designed as a baffle plate. The use of a designed as a baffle jet disintegration device is useful if the associated noise can be neglected in favor of a special effective deceleration of the incoming liquid flow. From the partial longitudinal section in FIG. 15 It is clear that the inflowing liquid flow impinges on a plate plane 26, which is arranged transversely to the inflow direction or jet regulator longitudinal axis. From this plate plane 26 of the liquid flow flows in the radial direction to flow openings 27, which are provided at the circulating around the plate plane 26 peripheral wall. The liquid stream divided into individual streams in the throughflow openings 27 can then continue to flow to the jet regulating device 4 and / or to the flow rectifier 14, which are connected downstream of the jet decomposing device 2 in the flow direction.

The in FIG. 15 illustrated jet regulator also has a built-in housing 6, which is divided into two detachably connectable housing parts 7, 8. While the inflow-side housing part 7 is firmly and permanently connected to the designed as a baffle jet decomposition device 2, are in the sleeve-shaped downstream housing part 8 two Inserted inserted parts, which have both honeycomb flow openings. While the comparatively thin and with small flow openings provided inflow-side insertion part 5 serves as Strahlreguliereinrichtung, the thicker and provided with large flow openings downstream Einsetzteil forms a flow straightener, which forms the individual jets into a homogeneous total beam. In this case, the outflow-side insertion part forming the flow rectifier rests on a radial peripheral edge 28 of the housing part 8, while the inflow-side insertion part 5 is supported on the outflow-side insertion part with a central spacer 29.
