Abstract

The invention relates to a sanitary outlet unit (1, 10), wherein flow-through channels (4) are formed in a jet former (3) in such a way that the flow-through channels are grouped around an axis (12) and that each flow-through channel (4) has a specified outflow direction (14), which is tilted both toward the axis (12) and perpendicularly thereto. The tilt toward the axis produces a converging jet pattern, and the tilt perpendicular thereto produces an additional optical effect (cf. Fig. 11).

Description

Sanitary outlet unit

The invention relates to a sanitary outlet unit which has a housing which is mountable on the water outlet of a sanitary outlet fitting and which has at its outlet end face a jet former which has flow-through channels which are arranged on the outlet end side of the housing and which discharges the water flowing out of the jet former Divide individual beams. Sanitary discharge units of the type mentioned above are known for example as so-called spray jet regulators. Such spray jet regulators regularly have a housing which can be mounted on the water outlet of a sanitary outlet fitting. The housing of this known spray jet regulator has at its outlet end face a jet former which has flow-through channels, which are arranged on the outlet end face on at least one circular path. With the help of these flow-through channels, the water emerging from the jet former is split up into individual individual jets so that a spray jet formed from visible individual jets emerges.

From DE 41 08 521 Al a jet shower with a shower head is known, which has a plurality of water outlet openings to form a shower jet, which are guided lying in an axial plane radially outward. By a flow deflection of the water flowing through the housing of the known jet shower water, a soft shower spray is to be generated. Efforts are being made today to provide sanitary outlet fittings with an aesthetically pleasing shape going beyond the intended use. It is always looking for ways to make the emerging from the outlet fitting water jet, for example, as a flood of water to make aesthetically pleasing.

It is therefore an object to provide a sanitary outlet unit of the type mentioned above, which is characterized by an aesthetically pleasing outlet spray pattern.

To achieve the above object, the features of claim 1 are provided in a sanitary outlet unit according to the invention. In particular, to solve the above problem in a sanitary outlet unit of the type described above, the invention proposes that for this purpose arranged on at least one closed path Durchströmkanäle each defining an outflow direction by a rotation in both by a housing longitudinal axis and a tangential to the closed Rail spanned plane as well as in a by the housing longitudinal axis and a complementary direction, which is perpendicular to the housing longitudinal axis and the tangential direction, spanned plane emerges from the housing longitudinal axis. Thus, an outflow jet image can be generated, which on the one hand, for example, by the first-mentioned rotation - has a twist and on the other hand - for example, by the second-mentioned rotation - assumes a deviating from a cylindrical shape outer contour. The outflow direction is thus tilted out of both mentioned levels. In particular, to solve the above problem in a sanitary outlet unit of the type described above according to the invention alternatively or additionally proposed that the arranged on at least one closed path Durchströmkanäle each define a AusStrömrichtung, both in a projection on a through a housing longitudinal axis and a tangential direction The closed plane spanned plane as well as in a projection on a plane defined by the housing longitudinal axis and a complementary direction, which is perpendicular to the housing longitudinal axis and the tangential direction, plane forms an angle with the housing longitudinal axis. Thus, a discharge jet image can be generated, on the one hand - for example, by the first-mentioned angle - an entanglement of located in a side to the outflow direction

Viewing position seems to have entangled rays and on the other hand - for example, by the second angle mentioned - assumes a deviating from a constant cross section outer contour.

In one embodiment of the invention can be provided that the outflow directions are given by a channel longitudinal axis of the respective flow channel. Thus, the outflow direction is easy by a shaping of the associated

Flow channel aligned.

In one embodiment of the invention it can be provided that the outflow directions of the flow-through channels in each case enclose an angle with the tangential direction, which for all

Durchströmkanäle located in the same quadrant. Thus, uniform swirl and / or uniform entanglement of the jet stream jets is independent of one Observer position achievable. Preferably, the angles are each selected equal to each other.

In one embodiment of the invention may alternatively or additionally be provided that the outflow directions of the flow passages each include an angle with the complementary direction, which for all

Durchströmkanäle located in the same quadrant. Thus, a uniform opening or constriction of the outlet jet pattern from all lateral viewer positions can be achieved. Preferably, the angles are each selected equal to each other.

In one embodiment of the invention can be provided that the outflow directions are inclined in a demarcated from the closed path interior. Thus, a waisted or tapered outer contour of the outlet jet pattern can be achieved.

In one embodiment of the invention can be provided that the closed path is a ring or circular path. Thus, the invention can be used in outlet units with round outer contour or round cross-section.

An inventive proposal for solving this problem is in the sanitary outlet unit of the type mentioned thus in particular that arranged on at least one annular or circular flow passages have an inclined both in the direction of the housing longitudinal axis and a direction towards a circumferential channel longitudinal axis.

Trained according to this invention proposal inventive outlet unit has a housing which is mounted on the water outlet of a sanitary outlet fitting to to let out the water emerging there with an aesthetically appealing spray pattern. At the outlet end face of the housing, a jet shaper is provided which has flow-through channels which are arranged on the outlet end face on at least one annular or circular path. The flow-through channels can be arranged on the outlet front side on a circular path or, for example, also on an elliptical annular path. These flow passages divide the water flowing out of the jet former into isolated individual jets in such a way that this outflowing water is formed from visible individual jets.

A preferred embodiment according to the invention aims at the fact that these individual jets form a mesh-like outflow jet image of the outflowing water. In addition or instead, these individual jets can also form a partially tapered, preferably waist-shaped, tapered outflow jet pattern. The flow channels arranged in at least one annular or circular path in the jet former of the outlet unit according to the invention have for this purpose a channel longitudinal axis inclined both in the direction of the housing longitudinal axis and in the direction of a circumferential direction. The outlet unit according to the invention is thus distinguished by its aesthetically pleasing discharge jet pattern.

Since the flow-through channels of the invention according to the invention described above proposal

Outlet unit are arranged on at least one circular path, provides a particularly simple and preferred embodiment according to the invention that the housing of this outlet unit has a round housing cross-section. In order to allow the individual jets forming the outflow jet pattern to emerge from the jet former in an arrangement which appears as homogeneous as possible, it is advantageous if all of the throughflow channels have the same angle of inclination.

The outflow jet image of the outlet unit according to the invention is particularly suitable if the flow channels are inclined in the direction of the housing longitudinal axis, that the outflowing individual beams form a ring zone with distance from the beam former, which is smaller than the optionally outer circular path with flow channels.

A further proposed invention for solving the above object provides in the outlet unit of the type mentioned above, that the flow channels are arranged on the outlet end side of the housing on at least two spaced-apart lines and that arranged on at least one line flow channels have a channel longitudinal axis, which is both inclined relative to the housing longitudinal axis in the direction of the adjacent line of flow channels and, relative to the plane of the outlet end face of this sanitary outlet unit, angled in relation to this line from the right angle. The outlet unit according to the invention designed according to this invention proposal has through-flow channels, which are arranged on the outlet end side of the housing on at least two spaced-apart lines. Of these flow-through channels, at least the flow channels arranged on one of these lines have a channel longitudinal axis which is inclined both in relation to the housing longitudinal axis in the direction of the adjacent line of flow channels and in relation to the plane of the outlet face of this sanitary outlet unit in relation to this line from the right Angled angle is different. The flow channels arranged on at least one line thus have angles which deviate from the right angle with respect to the axes of an XY and Z coordinate system, these flow channels being inclined in the direction of the flow channels arranged on the adjacent line. The individual jets flowing out of the flow-through channels seem to intersect several times line by line, so that a lattice-like or network-like interwoven structure of these beams is visible in side view.

In order to further improve this aesthetically pleasing outflow jet image of the individual rays exiting linearly, it is advantageous if all the flow-through channels have the same angle of inclination line by line.

It is possible that in one embodiment, arranged on a line flow channels have a channel longitudinal axis, which extend approximately parallel to the housing axis of the housing, while on the other hand on at least one other line arranged flow channels have a contrast angled channel longitudinal axis. However, an embodiment is preferred in which the pairs of mutually associated lines arranged flow channels are arranged point-symmetrical to each other.

Although it is conceivable, arranged on the outlet end face and a circular housing flow channels line by line to each other, - the linienweise arrangement of Durchströmkanäle is particularly advantageous feasible if the housing has a rectangular housing cross-section and if the housing with respect to the housing longitudinal sides narrow in cross-section Has housing narrow sides. A structurally particularly simple embodiment according to the invention provides that the beam shaper is designed as a perforated plate. It is advantageous if the outlet end face forming the jet former is held immovably relative to the housing of the outlet unit, in particular in the circumferential direction. For this purpose, it is particularly advantageous if the outlet plate of the housing forming perforated plate is integrally connected to the housing.

In order to limit the water consumption in a simple manner, it may be advantageous for the jet former to be preceded by a throttle narrowing the clear flow cross-section in the flow direction.

So that homogeneous and non-squirting individual jets can be formed in the jet former, which form a likewise homogeneous outflow jet pattern, it is advantageous if the jet former is preceded by a stream of water passing through a plurality of jet separators and / or a flow regulator in flow direction, which flow regulator the water flowing through regulates and limits pressure independently to a maximum flow volume.

It is possible that the jet former of the outlet unit according to the invention is preceded by only one jet separator and optionally a header or filter screen. In particular, at high water pressures, which can lead to high energy and to a strong turbulence of the exiting water, it is advantageous if the jet former a throttle or a flow regulator in the flow direction is upstream and if between the flow regulator or the throttle on the one hand and the beam former on the other hand, a beam splitter is provided. Thus, the comparatively fine clear opening cross-sections in the beam splitter and the beam shaper can not be accidentally closed by entrained in the water dirt particles, it is expedient if an intent or filter screen is arranged in the flow direction before the throttle, the flow regulator and / or the beam.

The outlet unit according to the invention can be configured with a comparatively small axial longitudinal extent if the jet splitter is designed as a pot-shaped diffuser which has burster openings on the peripheral wall of its pot shape and whose pot bottom serves as an impact surface which deflects the water flowing through to the burster openings. It may be advantageous if the Zerlegeröffnungen open in an annular gap which tapers in the flow direction. If this annular gap tapers in the throughflow direction, the water emerging from the decomposition openings in individual jets experiences a substantial increase in velocity, which leads to a negative pressure on the outflow side of the annular gap according to the Bernoulli equation. With the help of this negative pressure, ambient air can be sucked into the housing interior of the housing when needed and corresponding design of the outlet unit according to the invention, which is mixed there with the water flowing through.

In one embodiment of the invention can be provided that the flow channels tapering in the flow direction are formed. Thus, it is easily attainable that a desired discharge jet pattern is maintained over a longer distance. It is particularly advantageous if the flow channels each form a cone whose central axis is inclined relative to the housing longitudinal axis. Thus, a double inclined or tilted orientation of the outflow directions is easily accessible. The outflow direction can result, for example, from an angle bisector of an opening cone.

Alternatively or additionally, it may be provided that an opening angle of the flow-through channels is chosen so large that the flow-through channels are formed without undercut with respect to the housing longitudinal axis. The advantage here is that a simple demolding without multi-part molds can be achieved.

Further developments according to the invention will become apparent from the following description taken in conjunction with the claims and the drawings. The invention will be described in more detail below with reference to a preferred embodiment:

In the figures 1 to 16 three versions 1, 10, 100 of a sanitary outlet unit are shown. The sanitary outlet units 1, 10, 100 shown here have a housing 2 which can be mounted on the water outlet of a sanitary outlet fitting, not shown here. The housing 2 has at its outlet end face on a jet former 3, the flow channels 4, which are arranged at the outlet end face of the outlet units 1, 10, 100. These flow-through channels 4 divide the water flowing out of the jet former 3 into visible individual jets.

While the flow-through channels 4 of the outlet units shown in FIGS. 1 to 12 are arranged on a circular path, the through-flow channels 4 are those shown in FIGS. 13 to 16 shown outlet unit on two spaced apart and preferably arranged parallel to each other lines L, L ^x . 5 to 9, it is clear that the through-flow channels of the outlet unit 1 have a channel longitudinal axis 13 (cf., FIG 7 to 9). In this case, all flow channels 4 have the same angle of inclination.

The beam former 3 of the outlet units 1, 10, 100 is designed here as a perforated plate. While the flow-through channels 4 in the jet former 3 of the outlet units 1, 10 are arranged on at least one circular path, the flow-through channels 4 of the outlet unit 100 shown in FIGS. 13 to 16 are provided on at least two spaced-apart lines L, L ^x . This, the outlet end face of the housing 2 forming perforated plate may also be integrally connected to the housing 2.

In FIGS. 1 and 10, it can be seen that the jet former 3 is preceded by a stream of water flowing through it into a plurality of jet separators 5 which split the individual beams. The jet splitter 5 of the discharge units 1, 10 shown in FIGS. 1 and 10 is here designed as a pot-shaped diffuser 6 which has on the circumferential wall of its pot former openings 7, which are arranged at equal intervals in the circumferential direction. The pot bottom of the cup-shaped diffuser 6 is provided as a baffle 8, which deflects the water flowing through to the Zerlegeröffnungen 7. The Zerlegeröffnungen 7 open at the outer periphery of the diffuser. 6 in an annular gap, which tapers in the direction of flow. For this purpose, the diffuser 6 is surrounded by a diffuser ring 8, wherein the annular gap between the diffuser 6 and the diffuser ring 8 is arranged.

The outlet unit shown in FIG. 10 additionally has a flow rate regulator 9, which adjusts the water flowing through to a maximum flow volume independently of pressure. This flow regulator 9 is connected upstream of the jet splitter 5 in the flow direction. Instead of the flow regulator 9 can also be used a throttle not shown here, the

Flow cross section in this area narrows and also reduces water consumption.

From a comparison of Figures 1 and 10 it is clear that the jet splitter 5 and possibly also the flow rate regulator 9 of the outlet units 1, 10 is a Vorsatz- or filter 11 upstream in the flow direction, which is to retain and filter out the lime and dirt particles entrained in the water which otherwise could impair the function of the following components of the outlet units 1, 10 and in particular of the jet separator 5, of the flow rate regulator 9 and of the jet former 3.

From a close-up consideration of FIGS. 5 to 9, it can be seen that the flow-through channels 4 are inclined in the direction of the housing longitudinal axis 12 such that the outflowing individual beams form a ring zone with a spacing from the beam former, and preferably before impinging in a water basin, which is smaller than that optionally outer circular path with the flow-through channels 4 of the jet former 3. In FIGS. 11 and 12, the outflow jet pattern is illustrated that the individual jets flowing out of the discharge units 1, 10 form. As shown in FIGS. 11 and 12, these individual jets form a mesh-like and partially tapered outflow jet pattern, which is aesthetically particularly appealing.

The outlet unit 100 shown in Figures 13 to 16 has a beamformer 3 having flow channels, the spaced-apart from one another and preferably arranged in parallel lines L, L ^x are arranged. The arranged on at least one line and here on both lines L, L 'provided flow channels 4 each have a channel longitudinal axis 13, which is inclined in one both with respect to the housing longitudinal axis 12 in the direction of the adjacent line of flow channels 4 and, based on the Level of the outlet end face of this sanitary outlet unit, angled in relation to this line from the right angle. In this case, all the through-flow line by line have the same inclination angle, the pairs arranged on the mutually associated lines L, L ^l flow passages 4 are arranged point symmetrically to each other. It can be seen from FIGS. 14 to 16 that the individual jets issuing from the jet former 3 of the discharge unit 100 form an outflow jet image apparently braided or fabric-like bent in side view, wherein the sectional plane of the individual jets intersecting each other at a distance is arranged above a washing or collecting basin should be. Also, the outlet unit 100 shown in Figures 13 to 16 is characterized by an aesthetically pleasing discharge jet image. FIGS. 17 to 25 show a further exemplary embodiment of a sanitary discharge unit according to the invention. Functionally and / or structurally identical to the preceding exemplary embodiments and similar components and functional units are in this case designated by the same reference numerals and not described again separately. The remarks on FIGS. 1 to 16 therefore apply correspondingly to FIGS. 17 to 25.

The exemplary embodiment according to FIGS. 17 to 25 differs from the preceding exemplary embodiments at least in that the through-flow channels 4 are not cylindrical but conically tapered. In particular, FIGS. 18 to 25 show that the cones are each tilted in relation to the housing longitudinal axis 12. The section C-C is parallel to the tangential direction 15 in a flow channel 4 to the closed path, which vebindet all flow channels 4 and here runs circular laid. Accordingly, FIG. 22 shows a section which extends in a plane which is spanned by the housing longitudinal axis 12 and the tangential direction 15. It can be seen that the outflow direction 14, which is given by the orientation of the flow channel 4 and in particular its channel longitudinal axis 13, is rotated in this plane relative to the housing longitudinal axis 12 and thus occupies an angle with the housing longitudinal axis 12. The section A-A is along a complementary direction 16 which is perpendicular to the

Tangentialrichtung 15 is laid, and thus extends in a plane which is spanned by the housing longitudinal axis 12 and the complementary direction 16. It can thus be seen in FIG. 23 that the outflow direction 14 is also rotated in this plane against the housing longitudinal axis 12 and thus has an angle with the housing longitudinal axis 12. The described inclinations of the channel longitudinal axes 13 are in this case formed in that the cones of the flow channels 4 each have geometric center axes which are tilted relative to the housing longitudinal axis 12 in the mentioned two levels.

The opening angle of the individual cones are in this case chosen so large that no undercuts are formed from the inflow side along the housing longitudinal axis 12. Thus, a mold can be easily removed from the mold.

FIG. 26 shows a modification of the exemplary embodiment according to FIGS. 17 to 25, in which additionally a flow rate regulator 9 is inserted. The angle data shown in the figures are merely illustrative of the preferred embodiments and may be implemented differently in other embodiments. In a sanitary outlet unit, it is thus proposed to design flow channels 4 in a jet former 3 in such a way that an outflow direction 14 predetermined by each flow channel 4 is tilted in two mutually perpendicular planes and / or two directions perpendicular to one another relative to a housing longitudinal axis 12.
