Abstract

The sanitary functional unit (2) is provided with an insertion housing, which is connected at an outlet end (8) of a sanitary outlet fitting (9) by an intermediate holder. The outlet end of the functional unit is defined by a capsule-shaped ring wall (14) at the insertion housing or at the intermediate holder.

Description

The invention relates to a sanitary functional unit with an insertion housing, which is held in a sleeve-shaped outlet mouthpiece and held therein interchangeable, which outlet nozzle at the outlet end of a sanitary outlet fitting is releasably fastened.

The invention also relates to a sanitary functional unit with an insertion housing, which is used directly or with the aid of an intermediate holder in the outlet end of a sanitary outlet fitting and held there releasably.

Conventional sanitary functional units, which are designed for example as a jet regulator or include a jet regulator, are regularly mounted with the aid of an outlet nozzle at the outlet end of a sanitary outlet fitting. These functional units can be used with their insertion in the sleeve-shaped outlet nozzle and kept interchangeable, while the outlet nozzle in turn with a male or female thread on a counter-thread at the outlet end of the outlet fitting is releasably fastened.

It has also already created a jet regulator, the jet regulator housing is designed as an insertable into the outlet end of a sanitary outlet fitting insert cartridge (see. DE 10 2005 010 551 B4 ). On the outer circumference of the jet regulator housing to an external thread is provided, which is releasably connectable with a complementary inner peripheral side internal thread at the outlet end of the sanitary outlet fitting. In this case, the previously known jet regulator is screwed so deep into the outlet end of the outlet fitting until its outlet end side terminates substantially flush with the outlet end face of the outlet fitting.

In these prior art jet regulators, which terminate substantially flush with the outlet end face of the outlet fitting, however, there is a risk that a slight amount of water flowing out of the outlet fitting may be due to gravity or due to adhesion forces to the outlet fitting and may flow down the outside circumference thereof as a trickle. This trickle leaves after the evaporation of a visible by interfering calcium deposits drop trace and can even lead to malfunction in sensor-controlled outlet fittings. This problem occurs especially in such outlet fittings reinforced whose outlet end is not angled perpendicular to the fitting body. If the outlet fitting is not mounted directly on the ceramic washbasin, but next to it, for example, on a not provided with a water drainage level, disturbing pools of water can often form there. This puddles even lead to greater damage when this, the outlet fitting bearing level is made of wood, wood veneer or other water-sensitive material for design reasons.

There is therefore a particular task, a sanitary To provide functional unit of the aforementioned type, in which a trespassing of water droplets on the outer circumference of the sanitary outlet fitting safely avoided and undesirable droplet traces on the outlet fitting and possibly also malfunction of this outlet fitting can be effectively counteracted.

If the sanitary functional unit is mounted with the aid of an outlet mouthpiece at the outlet end of a sanitary outlet fitting, the solution according to the invention is in particular that the downstream end edge of the sleeve-shaped outlet mouthpiece projects beyond the downstream end face of the functional unit and is designed as a protruding drip edge. In this case, the outflow-side end edge of the sleeve-shaped outlet mouthpiece forms a drainage edge projecting above the outflow-side end plane of the functional unit and preferably sharp-edged, at which the water can drip off, without fear of exceeding even single drops of water on the outlet fitting.

If the insertion of the sanitary function unit, however, used directly or with the aid of an intermediate holder in the outlet end of a sanitary outlet fitting and kept detachable there, the solution of the above task in particular provides that the downstream end plane of the functional unit by a sleeve-shaped annular wall on Einsetzgehäuse or am Intermediate holder is defined, which is designed as a projecting over the outlet end of the sanitary outlet fitting drip edge.

The functional unit according to the invention has a sleeve-shaped annular wall which defines the downstream end plane of this functional unit. This sleeve-shaped annular wall is designed as a over the outlet end of the sanitary outlet fitting projecting drip edge. The sleeve-shaped annular wall thereby forms a slight projection on which water can drip off, without the risk that individual drops of water can pass on the outlet fitting. Since in the functional unit according to the invention a trespassing of water droplets on the sanitary outlet fitting is avoided with certainty, even disturbing droplet traces and, where appropriate, malfunctions of the sanitary outlet fitting is effectively counteracted.

A rapid dripping of the water seeping out of the sanitary functional unit water is favored if the dripping edge forming a ring wall is formed comparatively sharp.

The intended as drip edge ring wall can already integrally formed during the manufacturing process of the functional unit according to the invention or, if necessary, subsequently connected only with this. For this purpose, a development according to the invention provides that the annular wall integrally formed on the inflow side adjacent housing portion of the insert housing or glued, welded, locked, bolted or the like is subsequently connected.

Even a small projection of the sleeve-shaped annular wall is sufficient to drain well from the functional unit according to the invention running water. A preferred embodiment, which does not appear disturbing, therefore provides that the drip edge or the annular wall over the adjacent housing portion of the insert housing about 1 to 5 mm, preferably about 2 to 3 mm, protrudes.

To avoid slipping over a water droplet on the sanitary outlet fitting, it is advantageous if the projection between the water outlet and the fitting edge is more than 1.0 mm.

In order not to adversely affect the attractive appearance of a sanitary outlet fitting, it is expedient if the functional unit according to the invention, which can be designed as a jet regulator, flow rate regulator, flow restrictor, backflow preventer or a combination of such functional elements, clearly receding in appearance and, for example, in the color of the outlet fitting configured or formed transparent. A preferred embodiment according to the invention therefore provides that the annular wall in comparison to the inflow side adjacent housing portion of a visibly different material, preferably made of a different colored and / or transparent material. The annular wall according to the invention can thus be made in comparison to the insertion of the same plastic or other plastic material, but in each case a visibly different material component is added, which gives the drip edge forming the ring wall a different appearance.

The dripping of the remaining at the outlet end side of the functional unit according to the invention water is substantially facilitated when the downstream end edge region of the drip edge and in particular the annular wall is designed sharp-edged.

To insert the functional unit according to the invention in a simple manner in the outlet end and from the outlet end of the outlet fitting Also be able to take out again, it is advantageous if the housing section adjacent to the annular wall on the inside or outside circumference has at least one tool engagement surface for an assembly and disassembly tool. For assembly and disassembly purposes, a corresponding tool can be attached to this at least one tool engagement surface in such a way that a high torque can be transmitted to the sanitary functional unit with the aid of the assembly and disassembly tool.

In order to be able to apply the torque required for assembly or disassembly to the jet regulator and its jet regulator housing, it may be advantageous if the annular wall has a tool engagement surface on its outlet-side end edge and / or on its outer periphery and / or on its inner circumference. This tool engagement surface can be formed, for example, by alternating projections and recesses into which a complementarily shaped assembly and disassembly tool can engage.

The solution according to the invention offers particular advantages in particular in those embodiments in which the insertion housing and / or the intermediate holder have a substantially cylindrical outer circumference.

A particularly advantageous embodiment according to the invention provides that on the downstream end edge of the annular wall on the inner peripheral side a cross-sectional constriction, an annular bead or the like constriction is provided. By such, at the downstream end edge of the annular wall provided on the inner peripheral side constriction of the exiting water jet is circumferentially constricted such that a homogeneous and non-squirting spray pattern is additionally favored.

Further developments according to the invention will become apparent from the claims and the description. Hereinafter, advantageous embodiments according to the invention will be described in more detail with reference to FIGS.

In the FIGS. 1 to 14 are sanitary functional units 1, 2, 3, 4, 5, 6 shown, which are used directly or with the aid of an intermediate holder 17 in the outlet end 8 of a sanitary outlet fitting 9 and held there releasably. The functional units 1, 2, 3, 4, 5, 6, which may be in the form of flow restrictors, flow rate regulators, backflow preventers or laminar jet formers or represent a combination of such functional elements, are designed here as preferably aerated jet regulators, which jet regulators are a homogeneous, non-spraying and in particular, should form pearly-soft water jet.

For this purpose, the functional units 1, 2, 3, 4, 5, 6 shown here have an insertion housing 10 which carries on its inflow side a front screen 11 for filtering out the dirt particles entrained in the water. On the inflow side of the insert housing 10, below the front screen 11, a jet splitter 12 is provided which decomposes the inflowing water into a plurality of accelerated individual jets. Due to the acceleration of the individual beams is on the downstream side the Strahlzerlegers 12 generates a negative pressure, which causes an intake of the ambient air. This ambient air is mixed in the interior of the insert housing 10 with the individual jets before the aerated individual jets are united by a downstream, latticed or net-like and here honeycomb-shaped flow rectifier 13 again to a homogeneous emerging total beam.

From the in FIGS. 3 and 4 Prior art jet regulator 1 are known, which can be used from the end face of the outlet fitting 9 in the outlet end 8, that the outlet end face of this jet regulator 1 is substantially flush with the outlet side end edge region of the outlet fitting 9. At the in FIGS. 3 and 4 However, there is a risk that at the outlet end face of the jet regulator 1 remaining water droplets, especially at such an angled outlet end 8, on the outer circumference of the fitting housing and can flow down so gravitationally caused that especially after the evaporation disturbing recognizable drop trace remains. Such a drop track can lead to malfunction especially in sensor-controlled outlet fittings.

In order to prevent the passage of water droplets from the functional unit 2, 3, 4, 5, 6 to the outlet fitting 9 in order to avoid undesirable droplet traces and to exclude in particular conditional malfunction, especially in a sensor-operated outlet fitting with security, have in the Figures 1 and 2 and 5 to 14 shown functional units 2, 3, 4, 5, 6, a sleeve-shaped annular wall 14, which defines the downstream end plane of the functional units 2, 3, 4, 5, 6 and as a projecting beyond the outlet end of the sanitary outlet fitting 9 Dripping edge is designed.

From the FIGS. 5 to 14 It is clear that the drip edge forming annular wall 14 at least at its downstream end edge region has a relation to the inflow upstream wall sections of the insert housing 10 or the intermediate holder reduced wall thickness, the downstream end edge region of this annular wall 14 is designed sharp-edged.

In Fig. 5 It can be clearly seen that a radially inwardly pointing annular bead is provided on the inner peripheral side of the edge wall of the annular wall 14, which causes a constriction which favors a homogeneous and non-spraying jet pattern of the exiting water jet.

The in the FIGS. 5 and 6 and jet regulators 2, 6, which are illustrated in FIGS. 13 and 14, have a multipart and preferably two-part insertion housing 10, on whose outflow-side and here also an external thread 15 bearing housing part 16, the annular wall 14 is integrally formed.

In contrast, the ring wall 14 in the in FIGS. 7 to 12 shown beam regulators 3, 4, 5 glued to the inflow side adjacent wall portion of the insert housing 10, welded, locked, bolted or otherwise attached as a posteriori.

In order not to disturb the outlet side projecting annular wall 14 in appearance, this can compared to the inflow side adjacent wall portion of the insert housing 10 or the intermediate holder 7 from a different color, preferably adapted to the color of the outlet fitting or from a transparent or transparent Be made of material.

The in the FIGS. 5 to 6 and 11 to 14 shown. Jet regulators 2, 5 and 6 have on the annular wall 14 on the inflow side adjacent wall portion of the insert housing 10 or the intermediate holder 7 a tool engagement surface for attachment of an assembly and disassembly tool, designed here as a crown-shaped profiling 18 and on the inside and / or outside of the Ring wall 14 is arranged. In the in the FIGS. 7 to 10 illustrated beam regulators 3 and 4 is provided on the outlet side end edge of the jet regulator housing designed as a crown-shaped profiling tool engagement surface, which covers the subsequently attached ring wall. In order to transmit the torque required for assembly and disassembly to the jet regulators 3 and 4, a comparably shaped tool engagement surface 18 'on the outside and / or - as here - provided on the inner circumference of the annular wall 14, with the next smaller assembly and disassembly tool compatible and formed by Aus- and indentations.

In the FIGS. 13 and 14 It is clear that the jet regulator 6 carries at its inflow-side peripheral edge region an annular flange which limits the insertion path of the insert housing 10 in the sleeve-shaped intermediate holder 7. Here, the intermediate holder 10 carries a peripheral external thread 15 which cooperates with an internal thread at the outlet end of the outlet fitting 9. In contrast, the insertion housing 10 in the FIGS. 5 to 12 illustrated jet regulator 2, 3, 4, 5 outer circumference provided the external thread to screw these jet regulator 2, 3, 4, 5 directly into the provided at the outlet end of the outlet fitting internal thread.

In the Figures 1 and 2 is shown as one according to the FIGS. 5 to 14 trained functional unit 2 in the outlet end 8 of a sanitary outlet fitting 9 is used so that the downstream end plane of the functional unit 2 is defined by the sleeve-shaped annular wall 14 on the insert housing 10, which serves as an annular over the outlet end 8 of the sanitary outlet fitting 9 dripping edge. With the help of this annular wall 14 at the lowest flow rate trespassing and adherence of water is prevented at the outlet fitting to counteract unwanted water pools on the fixture attachment and drip marks on the outer periphery of the sanitary outlet fitting 9 and thereby preclude conditional malfunction even with a sensor-operated outlet fitting 9 with certainty.
