Description

Technical Field

[0001] The present invention relates to a sanitary insert, in particular for insertion into an outlet fitting and / or a water pipe, comprising at least one housing part having a receiving space, at least one insertion screen inserted into the receiving space of the at least one housing part, and at least one decomposition unit located upstream of the insertion screen in the flow direction of the fluid. Background Art

[0002] Such sanitary inserts, in particular jet regulators, are known, wherein an inserted screen ensures homogenization of the jet and / or the incorporation of air.

[0003] Thus, DE 100 27 987 A1 shows a jet regulator having a jet regulator housing, in the housing interior of which a jet regulating device is arranged.

[0004] DE 10 2015 012 107 A1 discloses a jet regulator having a jet regulator housing, in whose interior at least one rectifier is arranged, which has at least one grid or reticular structure oriented transversely to the flow direction and composed of intersecting webs.

[0005] EP 3219860 A1 discloses a jet regulator having a jet regulator housing which can be or is mounted on a sanitary water outlet and in which a jet splitter is arranged. The jet splitter has flow holes which split the water flowing through the jet regulator housing into individual jets.

[0006] WO 2018 / 050285 A1 shows a sanitary unit having a sleeve-shaped spout piece that can be fitted onto the water outlet of a sanitary outlet fitting and has a sleeve interior space into which a sanitary functional unit having at least one functional element can be inserted.

[0007] For various reasons, such as when machine-controlled automated installation is not possible, sanitary inserts of the type mentioned above often still require at least partial manual assembly. This requires constant attention to the correct orientation of the insert screen relative to the housing components. For example, the insert screen may have flow openings that must be correctly oriented relative to the housing components and / or other insert screens for proper function of the insert screen. Correct orientation can sometimes be difficult or time-consuming during manual assembly. Summary of the Invention

[0008] It is therefore an object of the present invention to provide a sanitary insert and a method for producing the same, in which the installation of the sanitary insert is simplified.

[0009] According to the invention, this object is achieved by a sanitary insert having the features described below.

[0010] To achieve this object, the invention proposes a sanitary insert of the type mentioned in the introduction, characterized in that the sanitary insert is particularly intended for insertion into a fitting outlet and / or a water pipe, comprises at least one housing part having a receiving space, at least one insert screen inserted into the receiving space of the at least one housing part, and at least one disassembly unit located upstream of the at least one insert screen in the flow direction of the fluid, wherein at least one orientation aid is formed on the at least one housing part, and at least one mating orientation aid corresponding to the orientation aid is formed on the at least one insert screen, wherein the at least one orientation aid is designed as a centering pin, the at least one housing part has a first and a second orientation aid, the at least one insert screen correspondingly has a first and a second mating orientation aid, and the first and second orientation aids of the housing part are designed as two orientation aids of different designs. This results in the advantage that the insert screen can be correctly oriented relative to the at least one housing part more simply and therefore more quickly. This simplifies and speeds up installation overall.

[0011] Advantageous embodiments of the invention are described below, which can optionally be combined with the features described above, either alone or in combination with features of other advantageous embodiments.

[0012] The orientation aid can be characterized, for example, in that, at the beginning of the orientation of the two components relative to one another, in particular on a first orientation path, there is a relatively large (lateral) gap between the components in order to capture the embedded screen, which (lateral) gap decreases during the further orientation process, in particular on a second orientation path. The orientation path can be the path along which the embedded screen is inserted into the at least one housing component during insertion. Preferably, the orientation is the centering of the embedded screen within the at least one housing component and / or transversely to the insertion direction.

[0013] According to an advantageous embodiment, it can be provided that the insert comprises an outlet structure which forms the outlet side of the sanitary insert. The outlet structure can be formed by the at least one housing part or can be placed onto the at least one housing part, for example.

[0014] To enable particularly simple assembly of the sanitary insert, the present invention provides that the at least one housing component has a first and a second orientation aid, and that the at least one insert screen correspondingly has a first and a second mating orientation aid. Thus, the housing component and the at least one insert screen are oriented relative to one another by at least two orientation aids of different designs on the housing component and two mating orientation aids on the insert screen that match these. This allows for faster and simpler correct assembly of the components of the sanitary insert.

[0015] In order to be able to correctly orient the at least one embedded screen in the receiving space relative to the at least one housing part in a central position, according to the invention, the at least one orientation aid is designed as a centering pin, in particular with a non-circular cross-section. This makes it easier to insert the embedded screen into the receiving space. In particular, the centering pin can have a polygonal or multi-angular, preferably quadrilateral, cross-section. Therefore, in addition to orienting the embedded screen centrally in the receiving space, it is also possible to simultaneously achieve a correct rotational orientation of the embedded screen relative to the housing part around the axis of the centering pin. A variety of possible orientations can be specified, which can be defined, for example, by the number of angles of the centering pin. This makes it possible to achieve a central orientation of the at least two components relative to each other.

[0016] Alternatively or additionally, another advantageous embodiment may provide that the at least one orientation aid is formed at least on the inner side of a housing wall, in particular a housing component. In particular, the at least one orientation aid may be at least one orientation aid extending in the direction of insertion of the at least one embedded screen into the receiving space, preferably extending continuously in the direction of insertion of the at least one embedded screen into the receiving space. This allows for circumferential alignment of the at least two components relative to one another.

[0017] In order to be able to orient the at least two components particularly well relative to each other, it can be provided that the at least one cooperating orientation aid of the at least one embedded screen is formed by a sleeve, in particular a sleeve centrally formed on the embedded screen, and / or is formed on the outer circumference of the embedded screen.

[0018] According to an advantageous embodiment, the at least one orientation aid defines at least one guide rail along which the at least one insert screen is displaceably guided. Thus, in addition to the correct orientation during initial assembly of the components, the at least one orientation aid also ensures that the at least one insert screen is brought into the correct end position within the receiving space and cannot be twisted incorrectly relative to the housing component.

[0019] According to another advantageous embodiment, a plurality of orientation aids can be formed on the at least one housing part. These can be designed in particular as orientation aids extending in the insertion direction of the at least one embedded screen into the receiving space, preferably extending continuously in the insertion direction of the at least one embedded screen into the receiving space.

[0020] In order to be able to more easily achieve the correct rotation-related orientation of the at least one embedded screen, according to a further advantageous embodiment, it can be provided that the at least one embedded screen has a tooth structure that corresponds to the mating tooth structure of the at least one housing part. The tooth structure can in particular be a tooth structure that protrudes from the upper side and / or on the lower side, in particular in the edge region. The mating tooth structure can in particular be a mating tooth structure that is constructed in the bottom region of the receiving space. Thus, the correct orientation of the components relative to each other during installation can be better ensured by the interaction of the tooth structure and the mating tooth structure. Thus, in particular, it can be better recognized whether the components are in the correct end position, in particular because otherwise the components would not be able to rest against each other over a large area and / or gaps would form between them if they were not assembled correctly.

[0021] In order to be able to expand the functionality of the sanitary insert, it can be provided that the sanitary insert has at least two insertion screens which are inserted into the receiving space.

[0022] According to a particularly advantageous embodiment, it can be provided that the first embedded screen has a toothing structure and the second embedded screen has a mating toothing structure corresponding thereto in order to orient the two embedded screens correctly relative to each other.

[0023] According to another particularly advantageous embodiment, provision can be made for the at least one embedded screen to be fixed against rotation relative to the at least one housing part and / or the outlet structure by means of the interaction of the at least one orientation aid and the at least one mating orientation aid corresponding thereto, thereby ensuring optimal functionality.

[0024] In order to simplify the insertion of the at least one insert screen into the receiving space, according to a particularly advantageous embodiment, it can be provided that the at least one orientation aid is designed such that it widens in cross section in the insertion direction of the insert screen into the receiving space.

[0025] Alternatively or additionally, it may be provided that the free end of the at least one orientation aid has an insertion aid. The insertion aid may in particular be designed as a tip. This is preferably so that the at least one embedded screen can be more easily inserted into the receiving space in the correct insertion position with the aid of the insertion aid. The embedded screen can thus first be placed onto the tip using the orientation aid, so that the embedded screen is already centered relative to the housing part. Further orientation can then be performed by means of a centering core or circumferential orientation aid that cooperates with the other or the cooperating orientation aid before the embedded screen reaches its final position in the housing part.

[0026] According to another particularly advantageous embodiment, the disassembly unit can have at least one fixing element, wherein the interaction of the fixing element with the at least one orientation aid and / or insertion aid, in particular the aforementioned insertion aid, provides a torsion lock for the disassembly unit relative to the at least one housing part. This torsion lock also ensures that the disassembly unit is positioned correctly relative to the at least one housing part.

[0027] According to a particularly advantageous embodiment, it can be provided that the at least one orientation aid is designed as a centering aid.

[0028] According to one embodiment, it can be provided that the diameter, in particular the largest diameter, of the at least one orientation aid corresponds at most to the width of two diameters of the opening of the outlet structure.

[0029] In order to simplify the adjustment of the at least one insert screen into the receiving space, in particular by eliminating the need for adjustment at two different locations during the initial insertion of the insert screen, it can be provided that the first orientation aid is longer than the second orientation aid. Thus, initial contact is initially established only between the first orientation aid and the insert screen, and further alignment is then performed, for example, also by the first orientation aid and / or by the second orientation aid.

[0030] It can be particularly advantageous if the at least one disintegration unit is designed as a disintegration plate having a plurality of through-openings, in particular through-openings that are evenly distributed and / or of equal size.

[0031] According to an advantageous development, it can be provided that a screen is arranged upstream of the at least one decomposition unit in the direction of flow.

[0032] The object mentioned at the outset is also achieved according to the invention by a method for producing a sanitary insert as described below. This method can be used in particular for producing the sanitary insert described and / or claimed herein. To achieve this object, according to the invention, a production method can preferably be provided, in which at least one insert screen is placed onto a first orientation aid, in particular a first orientation aid designed as a centering pin, via a matching mating orientation aid. By inserting the insert screen into the receiving space up to a stop point within the receiving space, the at least one insert screen is finely aligned via a second mating orientation aid, in particular a mating orientation aid designed on the circumference of the insert screen, and a second orientation aid, in particular an orientation aid designed on the inside of the receiving space of the housing part. Initial contact is first established only between the first orientation aid and the insert screen, and further orientation is then achieved via the second orientation aid. This significantly simplifies the manual installation of the sanitary insert and therefore allows for a shorter installation time. BRIEF DESCRIPTION OF THE DRAWINGS

[0045] Figure 1-11 Two embodiments of a sanitary insert are shown, which is designated as a whole by the reference numeral 1. However, the invention is not limited to the examples shown in the drawings.

[0046] The sanitary insert 1 is respectively configured to be embedded in an outlet fitting and / or a water pipe. For this purpose, for example, at least one coupling can be configured on the outside of the housing part 2, which can be embedded in a corresponding mating coupling on the outlet fitting and / or the water pipe.

[0047] The at least one housing part 2 has a receiving space 3 which is designed such that at least one insert screen 4, 5 can be inserted or is already inserted therein. The at least one insert screen 4, 5 can have the function of evenly dividing the jet impinging on the insert screen 4, 5 and / or improving the air mixing of the jet by means of a ventilation device.

[0048] The sanitary insert 1 further comprises a splitting unit 6 for splitting the jet flowing into the insert 1 in the usage position into a plurality of individual jets. The splitting unit 6 is located upstream of the at least one insert screen 4, 5 in the flow direction 7, so that the incoming jet first strikes the splitting unit 6 and only then strikes the insert screens 4, 5.

[0049] The disassembly unit 6 can be designed, for example, as a disassembly plate, which is placed onto the housing part 2 , in particular on the open side of the housing part 2 .

[0050] In order to make it easier to manually install the individual components of the sanitary insert 1, Figure 1-11 The sanitary insert 1 of each embodiment has at least one orientation aid 8, 9. The at least one orientation aid 8, 9 can be designed as part of the housing part 2 or can be arranged thereon, for example.

[0051] A mating orientation aid 10 , 11 matching the at least one orientation aid 8 , 9 is formed and / or arranged on the at least one insertion screen 4 , 5 .

[0052] The at least one orientation aid 8, 9 cooperates with the at least one mating orientation aid 10, 11 in such a way that the at least one embedded screen 4, 5 is correctly oriented when inserted into the receiving space 3 and / or can only be inserted in the correct orientation relative to the housing part 2, in particular up to the end position.

[0053] The sanitary insert 1 further comprises an outlet structure 12, which forms an outlet side 13 of the insert 1. Water flowing through the insert 1 therefore leaves the insert 1 again at the outlet structure 12.

[0054] Figure 1-11 The embodiment shown in FIG has a first orientation aid 8 and a second orientation aid 9. Accordingly, the at least one embedded screen 4, 5 has a first mating orientation aid 10 and a second mating orientation aid 11. The advantage of providing multiple orientation aids 8, 9 and mating orientation aids 10, 11 is that the at least one embedded screen 4, 5 is adapted at different, in particular spaced-apart locations when inserted into the receiving space 3. This makes insertion simpler and therefore faster.

[0055] The first orientation aid 8 can be configured as a centering pin 14, for example. In particular, the centering pin 14 itself can be located approximately centrally within the accommodating space 3. Therefore, the at least one embedded screen 4, 5 can be inserted centrally into the accommodating space 3. A first matching orientation aid 10 designed as an opening is correspondingly configured on the embedded screens 4, 5, into which the centering pin 14 is inserted when the embedded screens 4, 5 are inserted into the accommodating space. The matching orientation aid 10 can be configured as a sleeve 19, for example, which is part of the embedded screens 4, 5 or is arranged on them. The first matching orientation aid 10 can be configured centrally on the at least one embedded screen 4, 5.

[0056] The centering pin 14 can also be designed to determine a predetermined orientation of the embedded screens 4, 5 in the direction of rotation. For this purpose, the centering pin 14 can, for example, have a non-circular cross section 15. The mating orientation aid 10, which is designed as an opening, can have a shape corresponding to the cross section 15. Therefore, the at least one embedded screen 4, 5 must first be put onto the centering pin 14 so that it can then be rotated around the centering pin 14 until the non-circular cross section 15 can be inserted into the opening in a matching manner. For example, it can be provided that the centering pin 14 has a polygonal or multi-angled, preferably square, cross section 15. It can be provided here that a plurality of possible orientations, but in particular a limited number of orientations, can be provided between the housing part 2 and the at least one embedded screen 4, 5.

[0057] Figures 1 to 11 The embodiment shown has a second alignment aid 9, which is formed at least on the inner side 16 of the housing wall 17 of the housing part 2. The second alignment aid 9 is designed as at least one guide structure extending in the insertion direction 18 of the at least one embedded screen 4, 5 into the receiving space 3.

[0058] The second mating orientation aid 11 is configured to match the second orientation aid 9 on the outer circumference of the at least one embedded screen 4, 5. When the at least one embedded screen 4, 5 is inserted into the receiving space 3, the mating orientation aid 11 at least partially rests on the orientation aid 9 and / or can be guided along the orientation aid when the embedded screen 4, 5 is brought into its final position. The second orientation aid 9 and / or the second mating orientation aid 11 can be configured, for example, as a material recess and / or a material accumulation.

[0059] exist Figures 1 to 11 In the embodiment shown, the second orientation aid 9 is at least partially designed as at least one guide rail 21, which preferably extends, in particular continuously, from the entrance to the receiving space 3 to the bottom area 33. The guide rail 21 can be formed, for example, by at least one rail, which is formed as part of the housing part 2 on the inner side 16 of the housing wall 17 or is arranged thereon.

[0060] In order to correctly orient the at least one embedded screen 4, 5 in the direction of rotation relative to the housing part 2 at least in the end position, the at least one embedded screen 4, 5 has a toothing structure 22. The toothing structure 22 can be formed on the upper side 24 and / or the lower side 25, in particular in the edge region 26. In particular, the toothing structure 22 can be formed by a plurality of teeth of equal or different widths in the circumferential direction, which can be inserted into correspondingly shaped recesses in the mating toothing structure 23. The mating toothing structure 23 of the at least one housing part 2 can be formed, for example, in the bottom region 33 of the receiving space 3. Preferably, each embedded screen 4, 5 can have a toothing structure 22 (see, for example Figure 8 ).

[0061] In such Figure 1-11In the illustrated embodiment of a sanitary insert 1 having a plurality of embedded screens 4, 5, the mating toothing 23 may also be formed alternatively or additionally on the second embedded screen 5. The interaction of the at least one toothing 22 and the at least one mating toothing 23 allows the embedded screens 4, 5 to be correctly oriented relative to one another and / or relative to the housing part 2, at least in the rotational direction. In the fully inserted position, it can be provided that the toothing 22 and the mating toothing 23 are in substantial or complete contact with one another. Preferably, the toothing 22 and the mating toothing 23 are each formed in an edge region 26 of the at least one embedded screen 4, 5 and / or in an edge region of the bottom of the receiving space 3.

[0062] By the cooperation of the at least one orientation aid 8, 9 and the at least one cooperating orientation aid 10, 11 corresponding to the orientation aid 8, 9, Figure 1-11 In the embodiment of , the at least one embedded screen 4 , 5 is secured against rotation relative to the at least one housing part 2 and / or the outlet structure 12 .

[0063] The at least one embedded screen 4, 5 has a plurality of openings, which can be formed by a mesh, for example. Therefore, by correctly aligning the housing part 2 with the embedded screens 4, 5, the holes of the outlet structure 12 can also be correctly aligned relative to the openings of the at least one embedded screen 4, 5.

[0064] In order to better retain the at least one insert screen 4 , 5 in the receiving space 3 , the at least one orientation aid 8 , 9 can be designed such that it widens in cross section 15 along an insertion direction 18 of the insert screen 4 , 5 into the receiving space 3 .

[0065] exist Figure 1-11 In the sanitary insert 1 of FIG. 1 , the free end or upper end of the at least one orientation aid 8 , 9 each has an insertion aid 27 . The insertion aid 27 can be designed as a tip 28 that widens in the insertion direction 18 . The insertion aid 27 makes it easier to insert the at least one insert screen 4 , 5 into the receiving space 3 in the correct insertion position.

[0066] The disassembly unit 6 has a plurality of fixing elements 29, which are formed on the underside and / or on the outer circumference of the disassembly unit 6. The interaction of the fixing elements 29 with the at least one orientation aid 8, 9 and / or the insertion aid 27 ensures that the disassembly unit 6 is fixed against rotation relative to the at least one housing part 2. Furthermore, the through-opening 31 of the disassembly unit 6 is correctly oriented relative to the downstream insertion screens 4, 5 and / or the housing part 2 and / or the outlet structure 12 in the flow direction 7. The fixing elements 29 can be configured, for example, as material recesses and / or material accumulations. The fixing elements 29 can be wedge-shaped, in particular.

[0067] The diameter, in particular the largest diameter, of the first orientation aid 8 , in particular of the centering pin 14 , corresponds at most to the width of two diameters of the opening of the outlet structure 12 .

[0068] exist Figures 1 to 11 In the insert 1 shown, a screen 32 is arranged upstream of the at least one decomposition unit 6 in the flow direction 7 .

[0069] The present invention therefore relates to a sanitary insert 1, in particular for insertion into an outlet fitting and / or a water pipe, comprising at least one housing part 2, which is open on one side and has a receiving space 3 accessible via the open side, at least one insertion screen 4, 5 inserted into the receiving space 3 of the at least one housing part 2, at least one decomposition unit 6, which is located upstream of the at least one insertion screen 4, 5 in the flow direction 7 of the fluid, and at least one orientation aid 8, 9, wherein at least one mating orientation aid 10, 11 corresponding to the orientation aid 8, 9 is formed on the at least one insertion screen 4, 5.
