The invention relates to a sanitary inserting unit with an insertion housing, which is mountable on one or in a water outlet of a sanitary outlet fitting and in the housing interior, a liquid path is provided which leads through the housing interior flowing water, wherein in the liquid path, a jet splitter with a plurality of Zerlegeröffnungen is provided, which divide the water flowing through into a plurality of individual jets, and with at least one, the jet splitter in the liquid path subsequent grid or network structure, and wherein at least one of the liquid path at least partially bypassing by-pass channel is provided.

A sanitary insert unit of the type mentioned above is already known with an insert housing that can be mounted on the water outlet of a sanitary outlet fitting with the aid of an outlet nozzle (see publication on the Internet at www.neoperl.net/de/oem/products/aerators/productlines/perlatorh cflowthru.html as well US DesPat D622,356 ). In the housing interior of the insert housing, a liquid path is provided, which leads through the housing interior flowing water. In order to mix the guided over the liquid path with ambient air and water to form a homogeneous, non-squirting water jet, a Strahlzerleger is provided with a plurality of Zerlegeröffnungen in the liquid path, which divide the water flowing through into a plurality of individual jets, wherein the jet splitter Fluid path is followed by at least one grid or network structure, which ventilated Combine individual jets before a homogeneous total jet of aerated water emerges from the insert housing. In order to allow filtered or aerated water to escape via a separate outlet of the sanitary inserting unit if required, a central by-pass channel is provided in the housing, bypassing the liquid path at least in sections and its downstream channel opening on the outlet end side of the insert housing protrudes.

In various low-water countries is in the water supply network only a very low water pressure and in other countries compliance with such a low flow per unit time is prescribed that can be effectively cleaned with this small amount of water per unit time, for example, a wet shaver or similar object. It is therefore an object to provide a sanitary inserting unit of the type mentioned above, which still offers the user the opportunity to clean objects with a powerful cleaning jet, even at low outflowing amounts of water per unit of time.

The inventive solution to this problem is in the sanitary inserting unit of the type mentioned in particular that the by-pass channel is designed as a nozzle for generating at least one accelerated liquid jet and that the by-pass channel to at least in a section a tapered has clear channel cross-section.

The insertion unit according to the invention has an insertion housing, which can be mounted on or in a water outlet of a sanitary outlet fitting. For this purpose, an external thread can be provided on the housing outer circumference of the insertion, which can be screwed with an internal thread in the water outlet. Possible but is also that the insert housing is insertable into a sleeve-shaped outlet nozzle, which can be screwed by means of a thread on a mating thread on the water outlet. In the housing interior of the insert housing a liquid path is provided, can be passed through the water flowing through. In this liquid path, a jet splitter is provided which has a plurality of Zerlegeröffnungen which divide the water flowing through into a plurality of individual jets. The jet splitter is followed in the liquid path at least one grid or network structure, which acts as a flow straightener or as a homogenizer and should form the coming of the jet splitter single rays optionally after enriching and mixing with ambient air to a leaking from the insert soft overall jet. The insertion unit according to the invention has at least one by-pass channel bypassing the fluid path at least in sections, which serves to generate at least one accelerated liquid or cleaning jet. In the total jet flowing out of the sanitary inserting unit, a liquid or cleaning jet accelerated in comparison to the total jet is thus produced by means of the at least one by-pass channel formed as a nozzle, which is characterized by an increased cleaning power compared to the rest of the overall jet.

In order to reduce the water consumption noticeably and to be able to set the flow rate to a low maximum value, it is advantageous if a flow rate regulator is provided in the inlet housing upstream of the jet splitter, which adjusts the water flowing through to a pressure-independent maximum flow rate.

A functionally reliable embodiment according to the invention, the can be produced inexpensively and save space in the insertion, provides that the flow regulator has at least one elastic annular throttle body which surrounds a regulator core and limits a control gap between itself and a, provided on the outer peripheral wall of the regulator core or surrounding the throttle body inner peripheral wall rule profiling which control gap changes under the pressure of the water flowing through such that the flow rate of the flow regulator does not exceed a pressure-independent maximum value.

So that an effective liquid or cleaning jet can also be formed in the by-pass channel by means of the comparatively low flow rate, it is advantageous if the by-pass channel tapers at least in at least one conical subsection in the direction of its downstream channel opening.

A structurally particularly simple and easily manageable embodiment according to the invention provides that the by-pass channel has an inflow-side channel opening, which is arranged in the liquid path below at least one of the burster openings and in particular below at least two of the burster openings. In this embodiment, a liquid or cleaning jet is generated from at least one single jet formed in the jet splitter. In this case, a particularly advantageous embodiment, which is distinguished by a particularly effective cleaning jet, provides that the smallest clear channel cross section of the at least one by-pass channel comprises a clear cross-sectional area which is smaller than the cross-sectional area of the burster opening opening into the inflow-side channel opening or as the sum of the clear cross-sectional areas of the in the inflow side Channel opening opening Zerlegeröffnungen.

In order to be able to form the liquid jet or cleaning jet without regard to the jet separator and, if appropriate, the upstream flow regulator, it may be advantageous if the by-pass channel penetrates the jet separator and possibly also the flow regulator.

It is possible that the jet splitter is designed as a perforated plate. In contrast, another embodiment, which offers advantages particularly at low water pressures, provides that the jet splitter is designed as a diffuser having a baffle surface, which deflects the inflowing water in the direction of Zerlegeröffnungen, which are provided in an outer peripheral wall of the diffuser. In this embodiment, the outflowing water is first braked and deflected at the baffle of at least in this sub-area, for example cup-shaped diffuser, before the thus redirected in particular outwardly water is divided into the Zerlegeröffnungen in individual jets, which Zerlegeröffnungen are provided in the outer peripheral wall of the diffuser.

So that only a limited volume of water per unit time in the insertion unit according to the invention to a soft, non-spattering Water jet is formed, it is advantageous if the flow rate regulator upstream of the jet splitter and, if appropriate, and is arranged in front of the / an inflow-side channel opening of the by-pass channel. If the flow rate regulator is also arranged in front of the inflow-side channel opening of the by-pass channel, a defined maximum value of the flow capacity can also be maintained, taking into account the hard liquid or cleaning jet generated in the by-pass channel.

Disturbances due to dirt particles entrained in the water flow can be avoided, and trouble-free operation of the insertion unit and its components can be achieved if the insertion unit has a filter screen which filter screen is arranged upstream of the jet splitter and optionally upstream of the flow regulator connected therebetween.

If the by-pass channel passes through the jet separator and possibly also an upstream flow regulator, it may be expedient if the inflow-side channel opening of the by-pass channel is arranged in the inflow direction immediately below the filter screen. It is also avoided that the entrained in the water dirt particles clog the provided in the by-pass channel nozzle opening or can only narrow.

A preferred embodiment according to the invention provides that the filter screen preferably widens conically in the direction of flow. This embodiment has the advantage that the, for example, from the inflow-side attachment or filter screen, a downstream jet regulator and, if necessary, a flow regulator connected therebetween or flow restrictor formed insertion unit can be formed at least at its outer peripheral edge with a comparatively small longitudinal extent, although the Sieboberfläche of in the inflow-side clear cross-section of the outlet fitting projecting header or filter screen was made comparatively large.

Another embodiment according to the invention provides that the filter screen has a funnel-shaped form, and that the funnel shape of the filter screen tapers in the direction of an inflow-side channel opening of the at least one by-pass channel.

In order that an external soft and non-squirting overall jet can be formed in the insertion unit according to the invention, which encloses a hard cleaning jet arranged in its center and easily accessible there, it is advantageous if the by-pass channel is arranged approximately coaxially to the longitudinal central axis of the insertion housing ,

A development according to the invention provides that the by-pass channel tapers towards a water jet in the direction of a preferably central nozzle opening, which nozzle opening has the smallest clear cross-section of the by-pass channel.

If necessary, to be able to provide a larger jet cross-section in the cleaning jet for cleaning purposes, it may be advantageous if the by-pass channel tapers in the direction of an annular gap in order to produce a ring jet.

This provides a structurally particularly simple embodiment according to the invention, that the by-pass channel has a cylindrical clear cross-section and that in the by-pass channel is inserted in the flow direction at least partially tapered insert that between its outer periphery and the inner peripheral wall of the by-pass channel limited to the annular gap.

In order to be able to design the cleaning jet without regard to the flow rate of an optionally upstream flow rate regulator, it is expedient if at least one uncontrolled flow channel leading to an inflow-side channel opening of the by-pass channel passes through the regulator core of the flow rate regulator.

It may be advantageous if the annular gap or the nozzle opening form a downstream channel opening of the by-pass channel. In this embodiment, an object to be cleaned can be arranged at a small distance below the channel opening of the by-pass channel, so that this cleaning jet impinges virtually unhindered on the object to be cleaned and there can fully develop its cleaning power.

In this case, a preferred embodiment according to the invention provides that the outflow-side channel opening of the by-pass channel is arranged approximately in an outflow-side end plane or at least as far as an outflow-side end plane of the insertion housing.

So that the water flowing through the liquid path in the insertion housing can be formed on the outlet side again into a soft and non-squirting overall jet, it is expedient if a grid structure is provided at the downstream end plane of the insertion housing with approximately honeycomb-shaped Grid openings. In this case, the webs forming the lattice structure may have a longitudinal extent oriented in the direction of flow, which is equal to or greater than the maximum clear opening cross section of the lattice openings. Due to the honeycomb-like configuration of the grid openings only a small resistance is opposed to the water flowing through, and yet it is particularly easy to form a non-squirting overall jet.

In order to be able to form a non-squirting overall jet out of the water guided in the liquid path and, if appropriate, also to favor the mixing of this water flow with ambient air, it is advantageous if at least one preferably annular insertion part is inserted into the insertion housing, which has a grid interposed in the liquid path - Has or network structure.

In this case, a preferred embodiment according to the invention provides that the insertion parts are arranged in the liquid path below the jet disintegrator.

In order to produce a sparkling-soft overall jet, it is advantageous if the sanitary insert part for mixing the water flowing through the liquid path with ambient air has at least one ventilation channel which preferably opens below the jet separator in the liquid path.

In the FIGS. 1 to 14 different versions 1, 6 and 12 of a sanitary inserting unit are shown. The insertion units 1, 6, 12 have an insertion housing 2, which is mountable to a water outlet 3 of a sanitary outlet fitting not otherwise shown here. The insert housing 2 of the insertion units 1, 6, 12 is to use from the inflow side in a sleeve-shaped outlet nozzle 4 until a provided on the outer circumference of the insert housing 2 annular flange 5 rests on serving as a support 7 annular shoulder on the inner circumference of the outlet nozzle 4. The outlet nozzle 4 is screwed with a thread 8 on a mating thread 27 on the water outlet 3, wherein the separation zone can be sealed by a sealing ring 29.

In the housing interior of the insert housing 2 of the insert units 1, 6, 12, a liquid path is provided, can be passed through the water flowing through. In this liquid path, a jet splitter 9 or 10 is provided, which has a plurality of Zerlegeröffnungen 11 and 13, which divide the water flowing through into a plurality of individual jets. The jet splitter 9, 10 of the insertion units 1, 6, 12 is in the liquid path at least one grid or network structure 14, 15 downstream, which acts as a flow straightener or homogenizer and coming from the jet splitter single rays optionally after their enrichment and mixing with ambient air to a form the insertion 2 emerging soft, non-squirting overall jet. The insertion units 1, 6, 12 have at least one by-pass channel 16 bypassing the fluid path, at least in sections, for generating at least one accelerated liquid or cleaning jet is determined. This by-pass channel 16 has for this purpose at least in a section a tapered clear channel cross-section. In the total jet flowing out of the insertion units 1, 6, 12, a cleaning jet accelerated in comparison to the total jet is thus produced with the aid of the at least one by-pass channel 16 designed as a nozzle, which is characterized by a high cleaning power.

In order to be able to generate a hard central cleaning jet in the total jet flowing out of the fluid path of the inserting units 1, 6, 12, which can easily be identified by its defined position in the beam cross section, the by-pass channel 16 is approximately coaxial with the longitudinal central axis of the inserting housing 2 the insertion units 1, 6, 12 arranged. The provided at the downstream end face of the insert housing 2 lattice structure 14, which is integrally formed here on the insertion housing 2, has honeycomb-shaped grid openings 17, although due to the longitudinal extent of this lattice structure 14 forming webs well lead and shape the flowing water, but this Water flow only a small resistance oppose. In the insertion housing 2 of the inserting units 1, 6, 12 annular insertion parts 28 are used, which have an interposed in the liquid path grid or network structure 15. The insert parts 28 of the insertion units 1, 6, 12 shown here have a spider web-like structure of concentric webs, which intersect at intersection nodes with radial webs. The formed in the insertion parts 18 grid or network structures 15 favor a thorough mixing of the flowing water with the sucked into the housing interior of the insert housing 2 ambient air.

The guided in the liquid path of the inserting units 1, 6, 12 water flow is divided into the Zerlegeröffnungen 11, 13 of the beam splitters 9, 10 in individual jets, these individual jets experience an increase in speed, which generates a negative pressure on the downstream side of the beam splitters 9, 10. With the help of this negative pressure ambient air is sucked into the liquid path. The sanitary inserting units 1, 6, 12 have for this purpose at least one ventilation channel, which opens in the liquid path below the jet splitter 9, 10. This at least one ventilation duct is designed here as a housing opening 18 provided in the housing peripheral wall of the insert housing 2.

In order to limit the amount of water flowing through per unit time to a specified maximum value, a flow rate regulator 19 is provided in the insertion housing 2 upstream of the jet splitter 9, 10, which adjusts the water flowing through to a pressure-independent maximum flow rate. The flow rate regulators 19 used in the insertion units 1, 6, 12 have an elastic annular throttle body 20 made of elastic material, which surrounds a regulator core 21 and between itself and a rule profiling 22 provided on the outer circumferential wall of the regulator core or the inner peripheral wall surrounding the throttle body 20 Control gap limits which control gap changes under the pressure of the water flowing through such that the flow rate of the flow regulator 20 does not exceed a pressure-independent maximum value.

In the in the FIGS. 12 to 14 shown insertion unit 12, the by-pass channel 16 on an inflow-side channel opening in the liquid path below a subset of Zerlegeröffnungen 11 and in particular below at least two of the burster openings 11 is arranged. So that a hard and effectively cleaning cleaning jet can be generated in the by-pass channel 16 of the insertion unit 12, this by-pass channel 16 is dimensioned so that its smallest light channel cross-section comprises a clear cross-sectional area which is smaller than the sum of Clear cross-sectional areas of the opening into the inflow-side channel opening Zerlegeröffnungen eleventh

In the in the FIGS. 6 to 11 and 12 to 14 Imaged insertion units 6, 12, the inflow-side channel opening of the by-pass channel 16 is disposed below each of the flow rate controller 19, so that the regulated by the flow rate controller 19 maximum value of the flow rate also taking into account the cleaning jet and the by-pass channel through the 16th guided amount of water is not exceeded.

In the in the FIGS. 1 to 5 and 6 to 11 shown insertion units 1, 6 passes through the by-pass channel 16 the beam splitter 9 and 10, - in the insertion unit 1 according to the FIGS. 1 to 5 In addition, the by-pass channel 16 also penetrates the flow rate regulator 19.

While the jet breaker 9 in the FIGS. 1 to 5 and 12 to 14 shown insertion units 1, 12 is designed as a simple perforated plate, the jet splitter 10 of the inserting unit 6 according to the FIGS. 6 to 11 designed as a diffuser, which has a baffle 23, which deflects the inflowing water in the direction of the Zerlegeröffnungen 13, which are provided in an outer peripheral wall of the designed as a diffuser jet separator 10. In FIG. 8 It can be seen that the outer peripheral wall of the diffuser 10 designed as a diffuser is surrounded by an annular surface 24, and that between the Außenumfangswandung and an annular gap is provided on this annular surface 24, which tapers at least in sections in the flow direction of the water. According to the Bernoulli equation, a negative pressure forms on the outflow side of the annular gap in the interior of the housing, with the aid of which ambient air can be drawn in.

So that dirt particles entrained in the pipeline network can not impair the function of the insertion units and their components, the insertion units 1, 12 have a filter screen 25 which is arranged upstream of the jet splitter 9 and optionally also upstream of the flow regulator 19 interposed therebetween. While the filter screen 25 of in FIGS. 12 to 14 the inserting unit 1 is funnel-shaped, the funnel shape of this filter screen 25 tapering in the direction of an inflow-side channel opening of the at least one by-pass channel 16 provided in the insertion unit 1 ,

In order to produce a lance-shaped central cleaning jet, the by-pass channel 16 tapers into the FIGS. 1 to 5 and 12 to 14 shown insertion units 1, 12 in the direction of a central nozzle opening, which nozzle opening has the smallest clear cross-section of the respective by-pass channel.

If necessary, to be able to offer a cleaning jet with an enlarged beam cross-section, the by-pass channel 16 tapers in the insertion unit 6 according to FIGS. 6 to 11 in order to produce a ring beam in the direction of an annular gap. The by-pass channel 16 of the inserting unit 6 has for this purpose a cylindrical clear cross-section, wherein in this by-pass channel 16 in the flow direction at least partially conically widening Kanaleinsetzelement 26 is inserted, which limits the annular gap between its outer periphery and the inner peripheral wall of the by-pass channel 16.

The annular gap or the nozzle opening of the by-pass channel 16 provided in the insertion units 1, 6, 12 forms a downstream channel opening. This outflow-side channel opening is arranged at the insertion units 6, 12 approximately in a downstream end plane of the insertion housing 2. Although the flow rate regulator 19 arranged upstream of the insertion units 1, 6, 12 can greatly attenuate the water jet emerging from the fluid path, in the insertion units 1, 6, 12 an additionally hard cleaning jet is additionally provided which nevertheless effectively cleans dirty hands, toothbrushes, Razors or other objects. In this case, a subset of the inflowing to the units 1, 6, 12 incoming water in the at least one by-pass channel 16 is collected, bundled there and then passed through a designed as an annular gap or as a hole nozzle opening. In the trained as a nozzle by-pass channel 16 results in the bundled, relatively hard emerging cleaning jet, which is strong enough to clean a soiled object better. If necessary, the guided through the by-pass channel 16 amount of water can be mitgeregelt by the upstream in the insert housing 2 flow rate regulator 19. The guided through the liquid path water flow, which is not collected in the nozzle-like by-pass channel 16, passes through, as in a conventional jet regulator or Strahlbelüfter, first the beam splitter 9, 10 and then the beam splitter 9, 10 downstream grid or Network structures 14, 15 as the flow straightener or also serve as a homogenizer. The focused in the insertion units 1, 6, 12 bundled, sharp cleaning jet is circumferentially enveloped by the effluent from the liquid path soft overall, so that the cleaning jet is virtually invisible. The user is given the impression of having an ordinary stream of water in front of him, but if necessary, a sufficient cleaning effect can be achieved.
