Description

Jet regulator and corresponding use

Technical Field

The present invention relates to a jet regulator having an outflow structure through which, in use, a jet is discharged, wherein the outflow structure has an outer annular region and an inner core region through which, in use, water of the jet is discharged simultaneously, wherein the outflow structure has a dividing element by which the outflow structure is divided into a plurality of cells, which cells each have a discharge opening.

The invention also relates to the use of the outflow structure of the jet regulator.

Background

Such jet regulators are known in practice and subject to examination.

It is known to use the outflow structure of a jet regulator to shape the discharged jet, for example with respect to the cross-sectional shape.

Disclosure of Invention

The invention is based on the following tasks: a novel design possibility is provided for the discharged jet of the jet regulator.

In order to solve the above-mentioned task, the features of claim 1 are provided according to the invention. In particular, in order to solve the above-mentioned object, in a jet regulator of the type described at the beginning, it is proposed according to the invention that at least a part of the separating element extending outwards in the outer annular region is configured thicker than at least a part of the separating element in the core region. The discharged jet can thus reach the core region and the outer region surrounding the core region in the annular region. By means of the thicker, extending separating element in the annular region of the outflow structure, a break-up in the circumferential direction can be produced in the annular region of the discharged jet, which break-up leads to a local concentration of the water course, which appears to extend over the core jet of the jet as a jet arm in the discharge direction of the jet.

The present invention has realized that dividing the (two-dimensional) outflow structure into a (two-dimensional) core region and a (two-dimensional) outer annular region can be used to achieve the division of the discharged (three-dimensional) jet into a (three-dimensional) core region of the jet forming the core jet and a (three-dimensional) annular region of the jet surrounding the core region by means of different topographical designs of the (two-dimensional) region. By virtue of the configuration according to the invention of the separating element, an additional free space in terms of the external design can be achieved, which involves the structuring of the annular region of the jet in the circumferential direction and results in a division into portions of the jet arms which appear as if they were on the core jet.

If the core region of the outflow structure is circular, a columnar core jet of the discharged jet can be achieved.

The thickness of the separating element may be measured transversely to the jet direction and/or along the discharge face of the outflow structure through which the jet is discharged.

Preferably, the portion of the outwardly extending separating element in the outer annular region is configured thicker than at least a portion of the outwardly extending separating element in the core region.

The separating element can be constructed to be flexible, for example in the case of a woven or textile outflow structure, or to be rigid, for example in the case of a grid-shaped outflow structure.

In a preferred embodiment, at least the outer annular region of the separating element is formed as a web.

In an advantageous embodiment, it can be provided that the core region defines a columnar core jet of the jet. A particularly regular basic shape can thus be achieved. The term "columnar core jet" may also include together a widening obtained after the outflow structure in the course of the jet for physical reasons.

In an advantageous embodiment, it can be provided that the annular region defines jet arms of the jet, which are each delimited in the circumferential direction. The structuring of the external portion of the jet can thus be effected in the circumferential direction, which results in a profile design in which the jet arms are present on the core jet.

In an advantageous embodiment, it can be provided that the jet arm is connected to the core jet of the jet, for example as already mentioned. Thus, it is still possible to provide a jet that does not diverge but can be perceived as a whole. Here or alternatively, it may be achieved that: the jet arm extends over the core jet of the jet, for example over the core jet referred to.

In an advantageous embodiment, it can be provided that the thicker and outwardly extending separating element of the annular region has a thickness which is at least twice the thickness of the thinnest separating element of the core region. Thus, separate elements of different thickness may also be used in the core region.

For example, it can be provided that the thicker and outwardly extending separating element has a thickness that is at least three times or at least five times the thickness of the thinnest separating element. The reference point for the thickness of the separating element may be, for example, the average thickness, the thickest part or the thinnest part of the separating element. It has been found that by means of this dimensional difference a visually particularly clearly perceptible construction of the fluidic arm can be achieved, which appears as a single structure without being separated from the overall structure.

In an advantageous embodiment, it can be provided that the annular region is separated from the core region by a circumferential separating web. In this way, a particularly clearly perceptible division of the jet into a core jet and an outer jet arm directed along the jet can be achieved.

In this case, it can be provided that the circumferential separating web has a greater thickness than at least one further circumferential separating web in the core region. It has been found that by the specific design of separate structures that are larger or more pronounced than the structures in the core region, a distinctly perceptible structuring can be achieved on the core jet. This may be achieved by slight variations in the core region which may leave the uniform nature of the core jet unchanged, while more pronounced structuring at the transition to and/or in the annular region results in a pronounced separately perceptible difference in the jet map. The further circumferential separation tab in the core region may be, for example, the thickest circumferential separation tab. Thus, the structural transformation leading to the annular region may be more pronounced than the structural transformation within the annular region.

In general, it can be said that the surrounding separating webs do not necessarily extend circularly. Depending on the basic pattern or pattern type of the outflow structure, for example, a polygonal course of the separating webs can also be formed.

In an advantageous embodiment, it can be provided that a distribution region is provided upstream of the outflow structure, which distribution region directs the flowing water both onto the annular region and onto the core region. The core jet and the jet arm can thus be made to exist simultaneously and complement each other in a simple manner.

In an advantageous embodiment, it can be provided that the distribution region is formed as a chamber. A distribution area is thus described which can be formed particularly easily.

In an advantageous embodiment, it can be provided that the distribution area is configured as a flow barrier. Thus, balanced distribution (e.g., characterized by pressure and/or flow) over a wide operating range may be achieved. Good results can be achieved with the aid of a distribution area made of porous material, such as felt, foam or plastic fabric.

In an advantageous embodiment, it can be provided that the radially outwardly extending separating element of the thicker design of the annular region has a slope, by means of which the associated outlet opening tapers in the jet direction. It has been found that these inclined portions create attractive jet shapes. It is envisaged that the inclined portion contributes to the effect that the jet arms do not extend fully in the jet direction, but rather meander over the core jet and cross each other-similar to the amount of water on a pebble bed in mountain streams.

It can be provided here that the taper in the annular region is configured more strongly than in the core region (at comparable or comparable points). The jet arms can thus be distinguished from one another more clearly than the jet fractions in the core jet.

Alternatively or additionally, it may be provided that the taper in the annular region is configured with the opposite sign to that in the core region. In the case of injection molding technology, this may mean that the annular region and the core region have to be demolded in opposite directions. By reversing the sign, a particularly well perceived structure can be constructed.

In an advantageous embodiment, it can be provided that the thickness of the circumferential (for example, the circumferential already mentioned) separating web between the annular region and the core region is at most the same as the radial extent of the smallest outlet opening in the annular region. Thus, the separation between the core jet and the jet arm may be smaller than the size of the jet arm, so that the jet arm adheres to the core jet. The thickness of the separating tab is preferably at least half the radial extent.

In an advantageous embodiment, it can be provided that the outlet opening in the annular region is formed in the shape of a ring segment. This has proven to be advantageous for the design of the profile.

In an advantageous embodiment, it can be provided that the outlet openings in the annular region are arranged symmetrically and/or uniformly distributed. A regular arrangement of a plurality of jet arms can thus be achieved.

In an advantageous embodiment, it can be provided that at least the thicker and outwardly extending separating elements of the annular region are oriented radially. It is envisaged that this results in a particularly pronounced division of the jet arms.

In an advantageous embodiment, it can be provided that the thicker and outwardly extending separating element of the annular region radially extends diametrically across the annular region. Thus a complete division of the annular region can be achieved. This may result in a particularly pronounced configuration of the jet arms and/or aid in visual separation of the core jet.

Alternatively or additionally, to solve the mentioned task, the features of the parallel usage claims are proposed. In order to solve the above-mentioned task, it is therefore proposed according to the invention in the case of a use of the type described at the outset that the outflow structure of the jet regulator serves to divide the discharged jet into a preferably cylindrical core jet and a jet arm extending over the core jet. A novel jet shape is thus formed, which can be characterized in particular by a non-constant cross-sectional shape in the course and at the same time by a constant outflow profile over time in practice.

It can be provided here that the jet regulator is constructed according to the invention, in particular as described above and/or as claimed below. The described jet shape can thus be realized in a structurally simple manner.

In one embodiment of the invention, it can be provided that the jet arm is attached to the core jet at least in the longitudinal section of the jet. Thus, the jet can still be perceived as a unit.

In one embodiment of the invention, it can be provided that the jet arms meander and/or cross each other at least in longitudinal section over the core jet. Thereby an interesting visual appearance design can be achieved.

Detailed Description

Fig. 1 to 3 are described in the following collectively.

The jet regulator 1 according to the invention is embedded in a per se known manner in a mouthpiece 2 which is screwed with a fitting 3, so that water is led through a fitting outlet 4 and through the jet regulator 1 for forming an exiting jet.

In another embodiment, threads are configured on the jet regulator 1, so that the mouthpiece 2 is not necessary. In a further embodiment, the mouthpiece 2 is provided with an internal thread in order to be screwed onto a mating external thread of the fitting 3.

The jet regulator 1 in fig. 1 comprises, by way of example, the following functional units in the flow direction: a pre-screen 5, a quantity adjusting stage 6, a diverter stage 7, a mixing stage 8, an outflow stage 9 and a sleeve 11.

In further embodiments individual ones of the functional units 5-8 may be omitted. Additional functional stages may be implemented.

The quantity control stage 6 is shown in fig. 1 as a quantity limiter, which sets a constant flow for a specific operating pressure independently of the pressure. In a further embodiment, a quantity reducer, for example a throttle valve, is implemented instead of a quantity limiter.

In the embodiment shown, the diverter stage 7 is configured as a diverter plate with holes 10. In a further embodiment, a further splitter stage 7, for example a diffuser, is implemented.

In general, the splitter stage 7 serves to divide the incoming water jet into a plurality of individual jets in order to decouple the flow behavior in the jet regulator 1 and downstream from the flow behavior in the fitting 3 and thus to achieve a desired defined jet pattern or jet formation and to achieve a desired defined jet quality.

The holes 10 are configured as nozzle-shaped in order to achieve acceleration of the individual jets, so that a negative pressure is generated after the splitter stage 7.

The mixing stage 8 is configured in the form of a chamber. In order to enhance the mixing effect, different grid-like or textile-like insertion elements 13 are inserted into the mixing stage 8.

Fig. 1 shows a specific option for two grid-shaped insertion parts 13, which are followed by a textile-shaped sieve, for example a plastic disk, as insertion parts 13. In another embodiment, the textile-shaped screen can also be a metal screen. In other embodiments, another configuration of the placement member 13 may be constructed and arranged.

The outflow stage 9 with the outflow structure 14 adjoins the mixing stage 8. The outflow structure 14 has outflow openings 15, 16, the length of which, in each case, can be greater than the thickness of the insert part 13, in particular of the grid webs of the insert part 13. Each discharge opening 15, 16 defines a cell 32 of the outflow structure 14.

The outflow structure 14 acts as a rectifier through these outlet openings 15, 16, which are generally longer than their inner diameter or their inner width, to eliminate turbulence there of the mixing stage 8.

The length of the discharge openings 15, 16 may be measured perpendicular or transverse to the inner diameter of the discharge openings.

As can be seen in fig. 2 and 3, the outlet openings 15, 16 in the core region 17 are partially closed, in particular in the vicinity of the radially extending separating element 20.

This serves to increase the flow resistance in the core region 17 in order to achieve a balanced distribution of water onto the core region 17 and the annular region 18.

It can furthermore be seen that the thicker, radially outwardly extending separating element 20 of the annular region 18 has a slope 28, by means of which the associated outlet opening 16 tapers in the jet direction.

The discharge openings 15 in the core region 17 are embodied in reverse and (slightly) widened in the flow direction.

Fig. 4a and 4b show another embodiment according to the invention, wherein the functional stages 5-8 are omitted to simplify the illustration. Structurally and/or functionally homogeneous or identical components and functional units are denoted by the same reference numerals and are not described separately. Accordingly, the statements made with respect to the foregoing embodiments apply accordingly.

The jet regulator serves to provide a higher flow level (instead of 1.5gpm to 2.2gpm in fig. 1), so that here the discharge openings 15, 16 do not have to be closed to a large extent.

Fig. 5a and 5b show another embodiment similar to the illustrations in fig. 4a and 4 b. Structural and/or functional homogeneous or identical components and functional units are again denoted by the same reference numerals and are not described separately. Accordingly, the statements made with respect to the foregoing embodiments apply accordingly.

The embodiment according to fig. 5a and 5b differs from the previous embodiments in that radial symmetry is also achieved in the core region 17.

The separating element 19 extends radially here and has circular or circumferential separating webs 24 and 26, the first separating web 24 separating or separating the core region 17 from the annular region 18 and the second separating web 26 being located inside the core region 17. The first separation tab 24 has a greater thickness than the second separation tab 26.

Between the thick separating elements 20 of the annular region 18 there are also non-thickened separating elements 29 which also extend radially, which continue selected separating elements 19 outwards from the core region 17.

Fig. 6a and 6b show another embodiment of a diagram similar to that of fig. 5a and 5 b. The same or identical components and units are again denoted by the same reference numerals and are not described again separately. Accordingly, the statements made with respect to the foregoing embodiments apply accordingly.

The embodiment according to fig. 6a and 6b differs from the embodiment according to fig. 5a and 5b in that an inclined portion 28 is additionally provided, which has already been discussed in relation to fig. 1.

Fig. 7a and 7b show another embodiment according to the invention. The same or identical components and units are again denoted by the same reference numerals and are not described again separately. Accordingly, the statements made with respect to the foregoing embodiments apply accordingly.

The embodiment according to fig. 7a and 7b differs from the previous embodiments in that a ventilation window 12 is provided, which ensures that air is sucked into the mixing stage 8 through the ventilation channel 31 during normal operation.

However, after the splitter stage 7 in the mixing stage 8a porous material is arranged, for example in the form of a felt, foam or plastic fabric, through which a portion of the water is led outwards via the ventilation window 12.

The original ventilation channel 31 leading to the end face now has the annular region 18 according to the invention, so that the jet pattern or jet formation is shown here as in fig. 9 and 10.

Fig. 8a and 8b show a further embodiment according to the invention in which the outflow stage 9 has an outflow structure 14 essentially formed by a large discharge opening 15, wherein the placement member 13 is arranged upstream of the discharge opening 15.

As can be seen from fig. 8a and 8b, the separating elements 19 in the core region 17 may extend linearly (radially or non-radially). In the example shown, the separating element 19 in the core region 17 is surrounded by a distribution region 27, in particular a porous material 30. The separating element 19 may be a (plastic) material or a (grid) tab of metallic structure, in particular a separating tab, wire or wire.

In the case of a jet regulator, it is therefore proposed to divide the outflow structure 14 into a core region 17 and an annular region 18 surrounding the core region 17, wherein the core region 17 defines the discharged jet 21 as a core jet 23, and the annular region 18 presets the outer side of the jet 21, wherein the outwardly extending dividing elements 19, 20 in the annular region 18 are dimensioned such that the jet 21 is divided on the outer side into jet arms 22.
