Description

The invention relates to a sanitary outlet unit with a jet regulator which has an inflow-side jet splitter with splitter openings which split the inflowing water into a plurality of individual jets, and which has an outflow-side hole structure made up of a plurality of spray openings through which the water from the jet regulator is shaped individual spray jets exits, as well as with an outlet mouthpiece, which has a connection thread at least on its inflow-side peripheral portion, with which the outlet mouthpiece can be screwed to a mating thread on the water outlet of a sanitary outlet fitting.

It is already known to mount a jet regulator at the water outlet of a sanitary outlet fitting in order to shape the water exiting there into, for example, a homogeneous, non-spraying and possibly pearly soft water jet.

Jet regulators have also already been created which allow the water flowing out at the water outlet of a sanitary outlet fitting to emerge in separate individual jets. Some of these outlet units of the type mentioned above, also referred to as spray jet regulators, have an outlet mouthpiece that has a connection thread on the inside or outside of its inflow-side circumferential portion, with which the outlet mouthpiece can be screwed to a mating thread on the water outlet of a sanitary outlet fitting. These known outlet units have an inflow-side jet splitter which divides the inflowing water into a plurality of individual jets before these individual jets flow inside the outlet mouthpiece to an outflow-side hole structure which has a plurality of Has spray openings through which the water exits the jet regulator in the form of individual spray jets.

The aim is to give different sanitary outlet fittings from different manufacturers a characteristic shape. In this case, the outlet fittings are also designed in the area of their water outlet, deviating from the usual circular outlet cross-section, on the outer circumference with a square or otherwise non-circular cross-section. One problem here is to mount the outlet mouthpiece of a sanitary outlet unit on this non-circular water outlet of the sanitary outlet fitting by means of a screw connection, which regularly requires a round cross-section of the two components to be connected, at least in the area of the screw connection.

There is therefore the particular object of creating a sanitary outlet unit of the type mentioned at the outset, in which the jet shape of the exiting water is adapted to the non-circular cross section of the sanitary fitting in the area of its water outlet.

One inventive solution to this problem in the case of the sanitary outlet unit of the type mentioned at the outset consists in particular in that the edge-side spray openings of the downstream hole structure are arranged outside a circular area projected axially in the direction of the hole structure, which form the splitter openings of the upstream jet splitter.

In addition or instead, a further inventive solution to this problem in the case of the sanitary outlet unit of the type mentioned at the outset can consist in particular in that the outlet mouthpiece has a triangular, square or polygonal cross-section on the outer circumference, and that the through the corner points of the hole pattern formed by the spray openings delimit a uniform triangle, square or polygon.

The sanitary outlet unit according to the invention has a jet regulator which has an inflow-side jet splitter which divides the inflowing water into a plurality of individual jets in the interior of the jet regulator. The water divided and swirled in this way in the jet regulator flows to a perforated structure which forms the outflow side of the jet regulator, where the water exits the outlet unit. This hole structure has a plurality of spray openings through which the water exits the jet regulator in the form of individual spray jets. The jet regulator is arranged in an outlet mouthpiece, which has a connection thread on the inside or outside of its inflow-side circumferential part, with which the outlet mouthpiece can be screwed to an external or internal thread on the water outlet of the sanitary outlet fitting. In order to be able to adapt the shape of the outlet mouthpiece in its outer circumference to the non-circular outlet cross-section of a sanitary outlet fitting, the outlet mouthpiece has, for example, a triangular, square or polygonal cross-section on the outer circumference. In order to let the outflowing water emerge with a non-circular and in particular a three-, four- or polygonal jet cross-section, although the outlet mouthpiece of the outlet unit according to the invention can be screwed onto a mating thread on the water inlet of the sanitary outlet fitting and although the outlet mouthpiece therefore has a round cross-section at least in this area one solution according to the invention provides that the edge-side spray openings of the downstream hole structure are arranged outside a circular area projected axially in the direction of the hole structure, which circular area forms the splitter openings of the upstream jet splitter.

In order to allow the outflowing water to exit in a shape-adapted manner, in particular with a triangular, square or polygonal jet cross-section, the further proposal of the invention provides that the lines running through the corner points of the hole pattern formed by the spray openings delimit a uniform triangle or square or a polygon. The water jet emerging in individual spray jets thus has a triangular, square or polygonal jet cross section and is thus uniform with respect to the outer circumference of the outlet mouthpiece. Since this non-circular jet cross-section of the exiting water is formed by the individual spray jets, it is ensured that the emerging water retains its non-circular, i.e. triangular, square or polygonal outlet jet pattern even over a longer distance, without this water necessarily becoming an unsteady round jet cross-section tried to change.

It is advantageous if the spray openings are arranged on the inlet side in parallel rows that are spaced apart from one another. In this way, the spray jets can be distributed approximately evenly over the jet cross-section.

A structurally simple and easy to manufacture embodiment according to the invention provides that the jet splitter is designed as a perforated plate which has a plurality of splitter openings that are spaced apart from one another.

It is advantageous if the splitter openings of the jet splitter designed as a perforated plate are arranged in concentric hole circles with respect to one another.

In contrast, another embodiment according to the invention provides that the jet splitter acts as a diffuser is formed, which has a pot-shaped diffuser insert with a pot bottom serving as a baffle surface, and which are provided on the pot circumference of the pot-shaped diffuser insert in the circumferential direction spaced apart from each other splitting openings which open into an annular gap narrowing in the flow direction. If the jet regulator is designed as a diffuser, the inflowing water can also be easily divided into the individual jets in the low-pressure range, which are then transformed into the spray jets in the outflow-side hole structure. This diffuser has a pot-shaped diffuser insert which has a pot bottom which serves as a baffle for the inflowing water. At this impact surface the water flowing to the jet splitter is slowed down and deflected radially outwards, where splitter openings spaced apart from one another in the circumferential direction are provided on the circumference of the cup-shaped diffuser insert. These splitting openings open into an annular gap which narrows in the direction of flow. Since the annular gap narrows in the direction of flow, a negative pressure is generated on the outflow side of this annular gap according to Bernoulli's equation, which, if necessary, can also be used in a ventilated jet regulator to suck in ambient air.

A preferred embodiment according to the invention provides that the diffuser insert is inserted from the inflow side into a diffuser ring of the diffuser, preferably releasably, and that the diffuser insert and the diffuser ring delimit the annular gap between them.

The non-circular external appearance of the water emerging from the outlet unit according to the invention is determined in particular by the spray openings which form the corner points of this hole pattern. With it this formative effect of the spray jets emerging in the corner areas is additionally favored, it is advantageous if the spray openings arranged in the corner areas of the hole pattern of the hole structure have a larger clear flow cross-section compared to the other spray openings of the hole structure.

In order to promote the cleaning effect of the water emerging in spray jets and to prevent these spray jets from flowing together in an uncontrolled manner over the greatest possible distance, it is advantageous if the longitudinal axes of the spray openings in the outer areas of the perforated structure are angled outwards.

A uniform distribution of the spray jets in the jet cross-section of the overall jet generated by them favors when the longitudinal axes of the spray openings arranged in a central area of the perforated structure are approximately coaxial with the longitudinal axis of the jet regulator, and when the remaining spray openings are increasingly angled outwards towards the outer area of the perforated structure.

A uniform distribution of the spray jets over the entire jet cross-section of the exiting water is already promoted in the interior of the jet regulator of the outlet unit according to the invention if the jet splitter has a round outer circumference.

To this end, in a preferred exemplary embodiment according to the invention, it is provided that the diffuser insert and / or the diffuser ring have a round outer circumference.

A structurally simple and comparatively easy to manufacture embodiment according to the invention provides that the jet regulator has a jet regulator housing which is pot-shaped at least in its downstream partial area is formed, and that the pot bottom of this pot-shaped housing portion is formed by the hole structure having the spray openings.

In order to be able to manufacture the jet regulator used in the outlet unit according to the invention with as little effort as possible, even if the jet regulator housing still has a round cross-section in the area of the screw connection of the outlet unit according to the invention, which in the area of the outflow-side hole structure into a triangular, square or polygonal cross-section passes over, it is advantageous if the jet regulator has an at least two-part jet regulator housing and has at least one inflow-side and at least one cup-shaped outflow-side housing part.

A preferred embodiment according to the invention provides that the at least one inflow-side housing part can be inserted from the inflow side up to a first insertion stop in the outlet mouthpiece, and that the at least one outflow-side housing part can be inserted from the outflow side up to a second insertion stop into the outlet mouthpiece can be used.

In order to mount these housing parts captively, but possibly also easily detachable, in the outlet mouthpiece of the outlet unit according to the invention, it can be useful if the at least one inflow-side housing part and the at least one outflow-side housing part in the outlet mouthpiece can preferably be releasably latched into one another.

According to a further advantageous embodiment according to the invention, it is provided that the at least one outflow-side housing part is designed as a hollow body, and the outer peripheral side is designed as a hollow body Has shape-adapted triangular or square or polygonal cross-section, and that this hollow body has a round insertion opening on its inflow-side end face for inserting the at least one, in cross-section on the outer circumference of the inflow-side housing part.

In order to mount the jet splitter in the outlet mouthpiece of the outlet unit according to the invention, it is advantageous if the perforated plate having the splitter openings can be inserted into the outlet mouthpiece from the inflow side up to an insertion stop.

Developments according to the invention emerge from the drawings in conjunction with the claims and the description. Preferred exemplary embodiments of the invention are presented in greater detail below.

In the Figures 1 to 18 various versions 100, 108, 111, 114 of a sanitary outlet unit are shown. The outlet units 100, 108, 111, 114 shown here have an outlet mouthpiece 1, which has a connection thread 2 at least on its inflow-side peripheral portion, with which the outlet mouthpiece 1 can be screwed to a mating thread on the water outlet, a sanitary outlet fitting not shown here. The connection thread 2, which can also be designed as an external thread with a corresponding design of the outlet mouthpiece 1, is designed here as an internal thread. As from a comparison of the Figures 1 to 18 becomes clear, the outlet mouthpiece has a triangular or square, but possibly also a polygonal cross-section on the outer circumference. While the outlet mouthpiece 1 in the Figures 1 to 13 and 17 to 18 outlet units 100, 108 and 111 shown has a quadrangular cross-section on the outer circumference, the one shown in FIG Figures 14 to 16 The outlet unit 114 shown has a triangular cross section on the outer circumference.

From the Fig. 1 , 5 to 7 , 8, 10 , 11, 13 , 14th and 17 to 18 it becomes clear that the outlet units 100, 108, 111 and 114 shown here have a jet regulator 3 which has an inflow-side jet splitter 4 or 5 which divides the inflowing water into a plurality of individual jets. This jet regulator 3 has an outflow side and in the Figures 2 , 3 , 6th , 8th , 10 , 13th and 15 to 16 Hole structure shown in more detail consisting of a plurality of spray openings 6 through which the water exits from the jet regulator 3 in the form of isolated spray jets. In order to be able to adapt the outer circumference of the outlet mouthpiece 1 of the outlet units 100, 108, 111 and 114 to the non-circular outlet cross-section of the sanitary outlet fitting, the outlet mouthpieces 1 of the outlet units 100, 108, 111 and 114 are also three-, four- or otherwise polygonal and thus formed uniformly. In order to allow the outflowing water to emerge with a triangular, square or polygonal jet cross-section, it is provided that the lines running through the corner points of the hole pattern formed by the spray openings 6 delimit a correspondingly uniform triangle, square or polygon. Since this non-circular jet cross-section of the exiting water is formed by the individual spray jets, it is ensured that the exiting water retains its non-circular, i.e. triangular, square or polygonal outlet jet pattern, even over a longer distance of the water jet, without this water inevitably becoming restless tried to change round beam cross-section. In the Fig. 2 , 3 , 8th , 15th , 16 and 17 to 18 it can be seen that the spray openings 6 forming the outflow-side hole structure are arranged on the inlet side in parallel rows spaced apart from one another. In this way it is ensured that the hole structure of the jet regulator 3 emerging water is distributed approximately evenly over the entire cross-section of the outlet jet.

From a comparison of the Fig. 13 and 18th on the one hand as well as the Figs. 1 to 12 and 14 to 17 on the other hand, it becomes clear that the jet splitter 3 provided in the jet regulator 3 of the outlet units 100, 108, 111 and 114 can be designed either as a perforated plate or as a diffuser. So the beam splitter 5 is in the Figures 11 to 13 and 18th The illustrated outlet unit 111 is designed as a perforated plate which has a plurality of separating openings 7 spaced apart from one another. These splitter openings 7 of the jet splitter 5 designed as a perforated plate are arranged in concentric hole circles with respect to one another.

In contrast, the jet splitter 4 is in the Figures 1 to 10 and 14 to 17 The outlet units 100, 108 and 114 shown are designed as a diffuser which has a pot-shaped diffuser insert 8 with a pot bottom serving as a baffle surface 9. On the circumference of the cup-shaped diffuser insert 8, separating openings 10 spaced apart from one another in the circumferential direction are provided, which open into an annular gap 11 which narrows in the flow direction Pf1. In the Fig. 6, 7 , 8 and 10 it can be seen that the diffuser insert 8 can be inserted preferably detachably from the inflow side into a diffuser ring 12 of the diffuser 4. The diffuser insert 8 and the diffuser ring 12 delimit the annular gap 11, which narrows in the flow direction.

From the longitudinal sections according to Fig. 6 , 10 and 13th as well as from the top views in Fig. 17 and 18th it can be seen that the edge-side spray openings 6 are arranged in the downstream hole structure outside a circular area projected axially in the direction of the hole structure, which The circular area forms the splitter openings 7 of the jet splitter 4, 5 on the upstream side. In the Fig. 6 , 10 , 13th and 17th 1 to 18 it can be seen that the longitudinal axes of the spray openings 6 in the outflow-side hole structure in the outer regions of the hole structure are angled outwards. In contrast, the longitudinal axes of the spray openings 6 arranged in a central region of the perforated structure run approximately coaxially to the longitudinal axis of the jet regulator 3, while the remaining spray openings 3 are increasingly angled outwards towards the outer region of the perforated structure.

From the longitudinal sections in the Fig. 6 , 10 and 13th it can be seen that the jet splitter 4, 5 of the outlet units 100, 108, 111 and 114 has a round outer circumference. For this purpose, the diffuser insert 8 and the diffuser ring 12 of the outlet units 100, 108 and 114 are each designed with a round outer circumference.

While the in Figures 8 to 10 The outlet unit 108 shown, the components of the jet regulator 3 are inserted directly into the outlet mouthpiece 1 from the inflow side, the jet regulator 3 of the outlet units 100, 111 and 114 has a jet regulator housing that is pot-shaped at least in its downstream sub-area. The pot bottom of this pot-shaped housing section is formed by the hole structure having the spray openings 6. In the case of the outlet units 100, 111 and 114 shown here, the jet regulator 3 has an at least two-part jet regulator housing and for this purpose has at least one housing part 13 on the inflow side and at least one cup-shaped housing part 14 on the outflow side Fig. 13 can be seen, in the outlet unit 111 shown there, the at least one inflow-side housing part 13 can be inserted into the outlet mouthpiece 1 from the inflow side up to a first insertion stop 15, while in contrast the The outflow-side housing part of the outlet unit 111 is inserted into the outlet mouthpiece 1 from the outflow side up to a second insertion stop 16. The upstream housing part 13 and the downstream housing part 14 in the outlet mouthpiece 1 of the outlet unit 111 can be locked into one another in such a way that these housing parts 13, 14 clamp an annular flange 17 forming the insertion stops 15, 16 on the inner circumference of the outlet mouthpiece 1 between them.

From a comparison of the Figures 6 and 7 it can be seen that the outflow-side housing part 14 of the outlet unit 100 can be designed as a hollow body, which has a triangular or - as here- quadrangular or even a polygonal cross-section that is shaped to match the outlet mouthpiece 1 on the outer circumference. This hollow body, which is square in cross section here, has a round insertion opening 19 on its front side on the inflow side, into which the housing part 13 on the inflow side, which is round in cross section on the outer circumference, can be inserted.

In the case of the Figures 8 to 10 The outlet unit 108 shown is the diffuser having the splitter openings 10 on the one hand and also the plate-shaped hole structure 18 having the spray openings 6 on the other hand from the outflow side of the outlet mouthpiece 1 into the outlet mouthpiece 1 each up to an insertion stop and clipped there if necessary.

The one in the Figures 11 to 13 The embodiment shown, the jet regulator 111 has a multi-part housing, with an inflow-side housing part 13 with a circular cross-section being latchable in an insertion opening of a cuboid outflow-side housing part 14. During the cuboid housing part 14 on the downstream side is inserted from the outflow side into the outflow-side receiving opening of a likewise cuboid outlet mouthpiece 1, the circular inflow-side insert part 13 is pushed into the outlet mouthpiece 1 until an outer circumferential annular shoulder on the upstream housing part 13 rests against a ring shoulder serving as an insertion stop in the sleeve interior of the outlet mouthpiece 1 Housing part 13 on the inflow side is latched in the insertion opening of the cuboid housing part 14 on the outflow side. In the longitudinal section in Fig. 13 It can be seen that the jet splitter 5 is designed here as a perforated plate formed in one piece into the inflow-side housing part 13, which has the splitter openings 7 oriented axially parallel to the longitudinal axis of the jet regulator in the plate plane of the perforated plate oriented transversely to the flow direction. In contrast, the spray openings 6 on the downstream end face of the jet regulator 3 are increasingly angled outwards from the center.

In the Fig. 17 and 18th it is indicated that the spray openings 6 arranged in the corner points of the hole pattern of the hole structure have a larger clear flow cross section compared to the other spray openings 6 of the hole structure.
