Abstract

In the case of a sanitary outlet unit (1, 10), it is proposed to design throughflow channels (4) in a jet shaper (3) in such a way that an outflow direction (14) predetermined by each throughflow channel (4) in two mutually perpendicular planes and / or around two perpendicular directions are aligned tilted against a housing longitudinal axis (12).

Description

The invention relates to a sanitary outlet unit which has a housing which can be mounted on the water outlet of a sanitary outlet fitting and which has a jet shaper on its outlet end face, which has flow channels which are arranged on the outlet end face of the housing and which feed the water flowing out of the jet shaper Split up isolated individual beams.

Sanitary outlet units of the type mentioned are previously known, for example, as so-called spray jet regulators. Such spray jet regulators regularly have a housing that can be mounted on the water outlet of a sanitary outlet fitting. The housing of this known spray jet regulator has on its outlet end face a jet shaper which has throughflow channels which are arranged on at least one circular path on the outlet end face. With the help of these through-flow channels, the water emerging from the jet shaper is divided into individual jets, so that a spray jet formed from visibly isolated jets emerges.

From the DE 41 08 521 A1 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 in an axial plane and positioned radially outward. A soft shower jet is intended to be generated by deflecting the flow of the water flowing through the housing of the known jet shower head.

Efforts are now being made to give sanitary outlet fittings an aesthetically pleasing shape that goes beyond the intended use. We are always looking for ways to also to design the water jet emerging from the outlet fitting, for example as a surge of water, in an aesthetically pleasing manner.

There is therefore the task of creating a sanitary outlet unit of the type mentioned at the beginning, which is characterized by an aesthetically particularly appealing outlet jet pattern.

To achieve the stated object, the features of claim 1 are provided in a sanitary outlet unit according to the invention. In particular, in order to achieve the stated object in a sanitary outlet unit of the type described at the beginning, it is proposed according to the invention that for this purpose the throughflow channels arranged on at least one closed path each define an outflow direction which is caused by a rotation in both a housing longitudinal axis and a tangential direction to the closed Path spanned plane as well as in a plane spanned by the housing longitudinal axis and a complementary direction which is perpendicular to the housing longitudinal axis and the tangential direction, emerges from the housing longitudinal axis. Thus, a discharge jet image can be generated which, on the one hand, appears to have a twist - for example due to the first-mentioned rotation - and on the other hand - for example due to the second-mentioned rotation - assumes an outer contour deviating from a cylindrical shape. The outflow direction is thus tilted out of both of the aforementioned planes.

In particular, in order to achieve the stated object in the case of a sanitary outlet unit of the type described at the outset, it is alternatively or additionally proposed according to the invention that the throughflow channels arranged on at least one closed path each define an outflow direction which both in a projection on a plane spanned by a housing longitudinal axis and a tangential direction to the closed path and in a projection on a plane spanned by the housing longitudinal axis and a complementary direction which is perpendicular to the housing longitudinal axis and the tangential direction, encloses an angle with the housing longitudinal axis . In this way, an outlet jet image can be generated which, on the one hand - for example through the first-mentioned angle - appears to have an entanglement of rays that are crossed in a viewing position laterally to the outflow direction and, on the other hand - for example through the angle mentioned in the second place - assumes an outer contour deviating from a constant cross-section .

In one embodiment of the invention, it can be provided that the outflow directions are given by a channel longitudinal axis of the respective through-flow channel. The outflow direction can thus be aligned simply by shaping the associated throughflow channel.

In one embodiment of the invention it can be provided that the outflow directions of the throughflow channels each enclose an angle with the tangential direction which is in the same quadrant for all throughflow channels. Thus, a uniform twist and / or a uniform entanglement of the rays of the outlet jet image can be achieved regardless of a viewer's position. The angles are preferably chosen to be equal to one another.

In one embodiment of the invention, it can alternatively or additionally be provided that the outflow directions of the throughflow channels each enclose an angle with the complementary direction which is in the same quadrant for all throughflow channels. So is a Uniform opening or constriction of the outlet jet image can be achieved from all lateral observer positions. The angles are preferably chosen to be equal to one another.

In one embodiment of the invention, it can be provided that the outflow directions are inclined into an interior space that is delimited by the closed path. A tapered or tapered outer contour of the outlet jet pattern can thus be achieved.

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

In the case of the sanitary outlet unit of the type mentioned at the outset, an inventive proposal for solving this problem consists in particular in that the throughflow channels arranged on at least one annular or circular path have a channel longitudinal axis that is 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 designed according to this inventive proposal has a housing which can be mounted on the water outlet of a sanitary outlet fitting in order to allow the water exiting there to flow out with an aesthetically particularly appealing jet pattern. On the outlet end face of the housing, a jet shaper is provided which has throughflow channels which are arranged on the outlet end face on at least one ring or circular path. The throughflow channels can be arranged on the outlet end face on a circular path or, for example, also on an elliptical ring path. These through-flow channels divide the water flowing out of the jet former into individual jets in such a way that this outflowing water is formed from visibly isolated individual jets.

A preferred embodiment according to the invention aims to ensure that these individual jets form a braided outlet jet image of the outflowing water. In addition or instead, these individual jets can also form an outlet jet pattern that tapers in areas, preferably tapering in the form of a waist. The throughflow channels arranged on at least one annular or circular path in the jet shaper 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 characterized by its particularly aesthetically pleasing outlet jet pattern.

Since the flow channels of the outlet unit according to the invention designed according to the inventive proposal described above are arranged on at least one circular path, a particularly simple and preferred embodiment according to the invention provides that the housing of this outlet unit has a round housing cross-section.

In order to allow the individual jets that form the outlet jet pattern to emerge from the jet shaper in an arrangement that appears as homogeneous as possible, it is advantageous if all through-flow channels have the same angle of inclination.

The outlet jet pattern of the outlet unit according to the invention is particularly pleasing if the flow channels are inclined in the direction of the housing longitudinal axis in such a way that the outflowing individual jets form an annular zone at a distance from the jet shaper, which is smaller than the possibly outer circular path with flow channels.

A further inventive proposal for solving the above object provides, in the case of the outlet unit of the type mentioned at the outset, that the throughflow channels on the outlet end face of the housing are arranged on at least two mutually spaced lines and that the throughflow channels arranged on at least one line have a longitudinal channel axis, which is both inclined relative to the housing longitudinal axis in the direction of the adjacent line of throughflow channels and, based on the plane of the outlet end face of this sanitary outlet unit, is angled in relation to this line of its own deviating from a right angle. The outlet unit according to the invention designed according to this proposal of the invention has through-flow channels which are arranged on the outlet end face of the housing on at least two lines spaced apart from one another. Of these throughflow channels, at least the throughflow 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 throughflow channels and, based on the plane of the outlet end face of this sanitary outlet unit, in relation to this of its line is angled differently from the right angle. The throughflow channels arranged on at least one line thus have angles deviating from the right angle with respect to the axes of an X-Y and Z coordinate system, these throughflow channels being inclined in the direction of the throughflow channels arranged on the adjacent line. The individual jets flowing out of the through-flow channels appear to cross each other several times in a line, so that a grid-like or network-like interwoven structure of these jets is visible in a side view.

In addition to this aesthetically pleasing outlet jet pattern of the individual jets exiting line by line improve, it is advantageous if all through-flow channels have the same angle of inclination line by line.

It is possible, in one embodiment, for the through-flow channels arranged on a line to have a longitudinal channel axis which runs approximately axially parallel to the longitudinal axis of the housing, while the through-flow channels arranged on at least one other line have a longitudinal axis that is angled in comparison. However, an embodiment is preferred in which the flow channels arranged on lines assigned to one another in pairs are arranged point-symmetrically to one another.

Although it is conceivable to arrange the flow channels arranged on the outlet end face of a circular housing in line with one another, the linear arrangement of the flow channels can be implemented particularly advantageously if the housing has a rectangular housing cross-section and if the housing has a narrower cross-section than the longitudinal sides of the housing Housing has 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 shaper is held immovable relative to the housing of the outlet unit, in particular in the circumferential direction. For this purpose, it is particularly advantageous if the perforated plate forming the outlet end face of the housing is integrally connected to the housing.

In order to limit the water consumption in a simple way, it can be advantageous if the jet shaper has a clear Flow cross-section narrowing throttle is connected upstream in the direction of flow.

So that homogeneous and non-spraying individual jets can be formed in the jet shaper, which also form a homogeneous outlet jet pattern, it is advantageous if the jet shaper is preceded by a jet splitter that divides the flowing water into a large number of individual jets and / or a flow rate regulator in the direction of flow, which flow rate regulator regulates and limits the water flowing through to a maximum flow volume independent of pressure.

It is possible that the jet shaper of the outlet unit according to the invention is only preceded by a jet splitter and, if necessary, an attachment or filter screen. In particular at high water pressures, which can lead to high energy and strong turbulence in the exiting water, it is advantageous if the jet shaper is preceded by a throttle or a flow rate regulator in the direction of flow and if between the flow rate regulator or the throttle on the one hand and the jet shaper on the other a jet splitter is provided.

So that the comparatively fine clear opening cross-sections in the jet splitter and in the jet shaper cannot inadvertently be closed by dirt particles carried along in the water, it is useful if an attachment or filter screen is arranged in the direction of flow in front of the throttle, the flow rate regulator and / or the jet splitter.

The outlet unit according to the invention can be configured with a comparatively small axial longitudinal extension if the jet splitter is designed as a cup-shaped diffuser that is attached to the circumferential wall of its Has pot-shaped decomposition openings and the bottom of the pot serves as a baffle that deflects the water flowing through to the decomposition openings.

It can be advantageous if the splitting openings open into an annular gap which tapers in the direction of flow. If this annular gap tapers in the direction of flow, the water exiting the splitting openings in individual jets experiences a significant increase in speed, which leads to a negative pressure on the outflow side of the annular gap according to Bernoulli's equation. With the help of this negative pressure, if necessary and with a corresponding design of the outlet unit according to the invention, ambient air can also be sucked into the interior of the housing, which air is mixed there with the water flowing through.

In one embodiment of the invention it can be provided that the throughflow channels are designed to taper in the throughflow direction. This makes it easy to achieve that a desired outlet jet image is retained over a longer distance.

It is particularly favorable if the flow channels each form a cone, the central axis of which is inclined with respect to the longitudinal axis of the housing. A double inclined or tilted alignment of the outflow directions can thus be easily achieved. The outflow direction can result, for example, from an angle bisecting an opening cone.

Alternatively or additionally, it can be provided that an opening angle of the throughflow channels is selected to be so large that the throughflow channels are designed without undercuts in relation to the longitudinal axis of the housing. The advantage here is that a simple demolding can be achieved without multi-part molding tools.

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. On its outlet end face, the housing 2 has a jet shaper 3 which has throughflow channels 4 which are arranged on the outlet end face of the outlet units 1, 10, 100. These through-flow channels 4 divide the water flowing out of the jet shaper 3 into visible individual jets.

While the flow channels 4 in the Figures 1 to 12 The outlet units shown are arranged on a circular path, the flow channels 4 in the Figures 13 to 16 outlet unit shown on two spaced apart and preferably parallel to each other arranged lines L, L '.

From an overall view, in particular the Figures 5 to 9 it becomes clear that the throughflow channels of the outlet unit 1 have a direction both in the direction of the housing longitudinal axis 12 (cf. Fig. 6 ) as well as a channel longitudinal axis 13 inclined in the direction of a circumferential direction (cf. Figures 7 to 9 ) to have. All through-flow channels 4 have the same angle of inclination.

The jet shaper 3 of the outlet units 1, 10, 100 is designed here as a perforated plate. While the throughflow channels 4 in the jet shaper 3 of the outlet units 1, 10 are arranged on at least one circular path, the throughflow channels 4 are in the Figures 13 to 16 outlet unit 100 shown is provided on at least two spaced-apart lines L, L '. This, the outlet face of the housing 2 perforated plate forming the housing can also be connected in one piece to the housing 2.

In the Figures 1 and 10 it can be seen that the jet shaper 3 is preceded by a jet splitter 5 which divides the flowing water into a plurality of individual jets. The jet splitter 5 in the Figures 1 and 10 The outlet units 1, 10 shown here are designed as a cup-shaped diffuser 6, which on the peripheral wall of its cup shape has decomposition openings 7 which are arranged at regular intervals in the peripheral direction. The bottom of the pot-shaped diffuser 6 is provided as a baffle surface 8 which deflects the water flowing through to the splitting openings 7. The splitting openings 7 open on the outer circumference of the diffuser 6 in an annular gap which tapers in the direction of flow. For this purpose, the diffuser 6 is encompassed by a diffuser ring 8, the annular gap being arranged between the diffuser 6 and the diffuser ring 8.

In the Figure 10 The outlet unit shown also has a flow rate regulator 9, which regulates the water flowing through to a maximum flow volume independently of pressure. This flow rate regulator 9 is connected upstream of the jet splitter 5 in the direction of flow. Instead of the flow rate regulator 9, a throttle (not shown further here) can also be used, which restricts the flow cross-section in this area and also reduces the water consumption.

From a comparison of the Figures 1 and 10 It becomes clear that the jet splitter 5 and possibly also the flow rate regulator 9 of the outlet units 1, 10 is preceded by an attachment or filter screen 11 in the direction of flow, which is intended to hold back and filter out the lime and dirt particles entrained in the water otherwise the function of the following components of the outlet units 1, 10 and in particular of the jet splitter 5, the flow rate regulator 9 and the jet shaper 3 could impair.

From looking at the Figures 5 to 9 It can be seen that the throughflow channels 4 are inclined in the direction of the housing longitudinal axis 12 in such a way that the outflowing individual jets form an annular zone at a distance from the jet shaper and preferably before they hit a water basin, which is smaller than the possibly outer circular path with the throughflow channels 4 of the jet shaper 3.

In the Figures 11 and 12 the outlet jet image is illustrated that the individual jets flowing out of the outlet units 1, 10 form. As the Figures 11 and 12 show, these individual jets form a network-like and regionally tapering outlet jet pattern that is particularly aesthetically pleasing.

The ones in the Figures 13 to 16 The outlet unit 100 shown has a jet shaper 3 with through-flow channels which are arranged on lines L, L 'which are spaced apart from one another and preferably arranged parallel to one another. The throughflow channels 4 arranged on at least one line and provided here on both lines L, L 'each have a channel longitudinal axis 13 which is inclined both in relation to the housing longitudinal axis 12 in the direction of the adjacent line of throughflow channels 4 and in relation to the Level of the outlet end face of this sanitary outlet unit, is angled in relation to this its line deviating from a right angle. In this case, all through-flow channels have the same angle of inclination line-wise, the through-flow channels 4 arranged on the lines L, L 'which are assigned to one another in pairs, being arranged point-symmetrically to one another. From the characters 14 to 16 it can be seen that the individual jets emerging from the jet former 3 of the outlet unit 100 here form an outlet jet pattern that appears to be bent like a braided or woven fabric in a side view, whereby the cutting plane of the individual jets that cross each other in lines should be arranged at a distance above a wash basin or collecting basin. Even those in the Figures 13 to 16 The outlet unit 100 shown is characterized by an aesthetically particularly appealing outlet jet pattern.

The Figures 17 to 25 show a further exemplary embodiment according to the invention of a sanitary outlet unit. Components and functional units which are functionally and / or structurally identical or similar to the preceding exemplary embodiments are denoted by the same reference symbols and are not described again separately. The remarks on the Figures 1 to 16 therefore apply to the Figures 17 to 25 corresponding.

The embodiment according to Figures 17 to 25 differs from the preceding exemplary embodiments at least in that the throughflow channels 4 are not designed to be cylindrical, but to taper conically. In particular, the Figures 18 to 25 that the cones are each inclined with respect to the housing longitudinal axis 12. The section CC is parallel to the tangential direction 15 in a through-flow channel 4 on the closed path which connects all the through-flow channels 4 and is circular here. Figure 22 time accordingly a section that runs in a plane that 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 alignment of the throughflow channel 4 and in particular its channel longitudinal axis 13, is rotated in this plane with respect to the housing longitudinal axis 12 and thus a Angle with the housing longitudinal axis 12 assumes. The section AA is laid along a complementary direction 16, which is perpendicular to the tangential direction 15, and thus runs in a plane that is spanned by the housing longitudinal axis 12 and the complementary direction 16. In Figure 23 it can thus be seen 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 formed in that the cones of the flow channels 4 each have geometric center axes which are tilted in relation to the housing longitudinal axis 12 in the two planes mentioned.

The opening angles of the individual cones are selected so large that no undercuts are formed from the inflow side along the housing longitudinal axis 12. A molding tool can thus be easily removed from the mold.

Figure 26 FIG. 13 shows a modification of the exemplary embodiment according to FIG Figures 17 to 25 , in which a flow rate regulator 9 is also used.

The angle information shown in the figures only serves to illustrate the preferred exemplary embodiments and can be implemented differently in other exemplary embodiments.

In the case of a sanitary outlet unit, it is therefore proposed to design throughflow channels 4 in a jet shaper 3 in such a way that an outflow direction 14 predetermined by each throughflow channel 4 in two mutually perpendicular planes and / or around two mutually perpendicular Direction is aligned tilted against a housing longitudinal axis 12.
