Description

1 / 15 Water-conducting arrangement and sanitary accessory with a water-conducting arrangement.

[0001] The present invention relates to a water-conducting arrangement, with a functional unit and at least one connecting hose.

[0002] Such water-conducting arrangements are known and used, for example, in sanitary fittings. Connecting hoses often serve to separate the function of conducting water to a functional unit, for example, a valve or a water outlet, from the function of mechanically holding the functional unit in the sanitary fitting. This often has the consequence that a fluid link from the connecting hose to the functional unit is concealed in the position of use in the sanitary fitting.

[0003] The present invention aims to develop a simple fluid link in a water-conducting arrangement.

[0004] To achieve the aforementioned objective, the characteristics of claim 1 are provided according to the present invention. Specifically, in a water-conducting arrangement of the type mentioned above according to the present invention, it is suggested that, at one end of the connecting hose facing the functional unit, a molded retaining flange is formed in a single piece, and that the retaining flange is engaged in a hose inlet of the valve. This makes a hose nozzle unnecessary in the connecting hose. This simplifies the production of the fluid connection. When no hose nozzle is needed, a clear internal cross-section can be selected, which is larger, while the external dimension remains the same. This is favorable for the lowest possible flow resistance.

[0005] For example, the functional unit could be a valve or a water outlet. The present invention can therefore be used, Petition 870260043322, dated 08 / 05 / 2026, p. 8 / 54 2 / 15 advantageously, in functional units, which are arranged in conditions of narrower spaces.

[0006] For example, the connecting hose can be a feed hose. Therefore, the present invention can also be used in connecting hoses with a relatively high operating pressure. Here, it can be foreseen, for example, that the connecting hose is a cold water hose. This can positively influence the long-term stability of the fluid connection.

[0007] For example, the connecting hose can also be a drain hose. The present invention becomes necessary here where an operating pressure on the drain side of a functional unit, due to the pressure drop across the functional unit, is often significantly lower than that on the feed side.

[0008] In one embodiment of the present invention, the connecting hose can be provided as being made from a thermoplastic material. This allows the retaining flange to be molded in a particularly simple manner.

[0009] In one embodiment of the present invention, it can be provided that the retaining flange is formed by thermoplastic deformation. In this case, it is advantageous that the connecting hose can be produced from an extruded material. The retaining flange can be molded, in this case, for example, after the connecting hose has been cut to length.

[0010] In one embodiment of the present invention, it can be provided that the hose inlet is opened laterally. This eliminates the need for the connecting hose to be threaded.

[0011] In one embodiment of the present invention, it can be provided that the hose inlet is formed circumferentially closed. Petition 870260043322, dated 08 / 05 / 2026, p. 9 / 54 3 / 15 This allows the retaining edge to be supported along the entire circumference.

[0012] In one embodiment of the present invention, it can be provided that a radial anchoring tie rod is formed in the retaining rim. This allows for the provision of removable protection. This is particularly advantageous in cases where the connecting hose partially loses its shape stability due to heating with the flow of hot water.

[0013] Here, it can be provided, for example, that the anchoring tie rod is formed as a groove or rib. Thus, a positive union between the retaining edge and the hose inlet can be produced by simple means. The hose inlet can be provided, for example, with a corresponding shape, particularly on a support surface.

[0014] The groove or rib may be formed, for example, circumferentially to support the retaining edge on all sides.

[0015] In one embodiment of the present invention, it can be provided that the retaining rim is pressed against a support surface at the hose inlet. This prevents the retaining rim from sliding out. This is particularly advantageous if the anchoring tie rod described herein is formed on the retaining flange. Through contact pressure, it can be achieved that the positive union of the anchoring tie rod does not accidentally come loose, even at hot water temperatures.

[0016] In one embodiment of the present invention, it can be foreseen that a bearing surface, for example, as already mentioned, can be formed at the hose inlet corresponding to the retaining flange. This makes it possible to produce a positive connection.

[0017] Here, it can be predicted, for example, that a radially acting anchor counter-tie rod will thus be formed. Through Petition 870260043322, dated 08 / 05 / 2026, p. 10 / 54 4 / 15 of the interconnection of the anchor tie rod and counter-tie rod can achieve a particularly firm support of the retaining edge.

[0018] This can be achieved, for example, by a positive connection between the hose intake and the retaining edge.

[0019] A simple model of a positive union is given by at least one rib, preferably circumferential, that engages in a groove. By means of this, an additional seal can be achieved.

[0020] At least one rib may be formed, for example, on the bearing surface and / or retaining edge.

[0021] In one embodiment of the present invention, it can be provided that the hose inlet has a circumferential support disc on which the retaining rim rests. In this case, it is advantageous that, regardless of the formation of the functional unit, multilateral support of the retaining rim can be achieved, particularly when the hose inlet is opened laterally.

[0022] Preferably, the backing disc is formed in a removable form. This can facilitate disassembly. Different materials can also be selected for the backing disc and for a support plate that holds the backing disc.

[0023] For example, it can be foreseen that the support disc is formed as a perforated piece and / or a bending piece. Thus, the support disc can be produced, for example, from metal, while the support plate of the aforementioned functional unit is made from synthetic material.

[0024] For example, it may be foreseen that the support disc is formed as a casting, particularly as a zinc casting. Thus, alternative materials may be used. Petition 870260043322, dated 08 / 05 / 2026, p. 11 / 54 5 / 15

[0025] Alternatively or additionally, it may be provided that the support disc be formed as a piece of synthetic material. This could be, for example, thermoplastic, in order to allow for simple production.

[0026] Alternatively or additionally, it can be provided that sharp edge structures are formed on a bearing surface, particularly as already described, for the retaining rim. These sharp edge structures can be fixed to the retaining rim to keep them in positive contact. This can be achieved particularly simply if the bearing disc is a perforated piece – for example, metallic – and / or a bending piece and / or a cast piece, particularly a zinc cast piece.

[0027] Through this, sharp-edged structures can present, for example, at least one retaining grid. With this, structures that can be produced in a particularly simple way are described.

[0028] In one embodiment of the present invention, it can be provided that a sealing surface is formed at the end of the connecting hose. In this case, it is advantageous that a sealing function can be integrated into the retaining rim. No additional sealing means are required. The connecting hose can thus be produced from a single component, since a sealing ring or such a sealing means can be provided in the functional unit.

[0029] The sealing surface can be formed, here for example, in a circumferential shape. Thus, it is possible to achieve a multilateral seal.

[0030] It can be predicted that the sealing surface will act axially. Therefore, a contact pressure, particularly the contact pressure described earlier, can be used in Petition 870260043322, dated 08 / 05 / 2026, page 12 / 54 6 / 15 retaining rim for a seal.

[0031] Alternatively or additionally, it may be provided that the sealing surface acts axially. Thus, an arrangement is described whose sealing effect is independent of a contact pressure on the retaining rim.

[0032] In one embodiment of the present invention, it can be provided that an axially acting bearing surface is formed on one feed side of the retaining rim. Thus, a sealing ring can be easily fitted.

[0033] Here it can be foreseen that an axial backseating surface will be formed on the valve. This can be provided, for example, by an implanted sealing ring.

[0034] In one embodiment of the present invention, it can be foreseen that a radially acting sealing surface is formed on a support, which projects on the feed side, by the retaining rim. Thus it is possible to construct a radial seal that can be produced particularly by thermoplastic molding.

[0035] Here it can be predicted that an axially counter-sealing surface will be formed on the valve. In this case, it is advantageous that a contact pressure from the valve can be applied to form a seal. Here too, a counter-sealing surface can be formed on a sealing ring.

[0036] In one embodiment of the present invention, it can be provided that a circumferential edge of an inlet opening at the end of the connecting hose has a sharp edge. This allows for a groove-free design of a transition between the connecting hose and the functional unit. Such grooves can cause turbulence in the flowing water and thus unintentionally reduce a clear effective cross-section at the transition.

[0037] For example, it can be predicted that the sharp edge is Petition 870260043322, dated 08 / 05 / 2026, page 13 / 54 7 / 15 formed with a tool without radii. Thus - particularly with thermoplastic molding - a simple tool can be used to obtain the smoothest possible transition.

[0038] Alternatively or additionally, it may be provided that the circumferential edge be formed flush with the valve. By means of this, it is possible to frequently avoid transverse flow narrowing and / or an increase in flow resistance. Preventing irregularities in the transition also reduces the possibility of dirt accumulation in this area.

[0039] In one embodiment of the present invention, the functionality can be provided as a mixing cartridge. This covers a common application case.

[0040] In one embodiment of the present invention, it can be provided that the connecting hose is a mixed water hose. The present invention takes advantage of the fact that the mixed water hose is often implemented at a low operating pressure and that, thereby, an overload can be reduced in the fluid connection at the retaining rim.

[0041] In a preferred application, for the solution of the present objective, a sanitary accessory with a water-conducting arrangement according to the present invention is suggested, particularly as described above and / or according to a claim directed to a water-conducting arrangement.

[0042] Here, it can be foreseen, for example, that the connecting hose is implemented as a drain hose for a sanitary fitting water outlet. With this, it is possible to achieve an operating pressure that differs only slightly from an ambient pressure if the pressure drop at the water outlet is low. This favors the requirements for a durable sealing capacity of the retaining rim. Petition 870260043322, dated 08 / 05 / 2026, page 14 / 54 8 / 15

[0043] Alternatively or additionally, it may be provided here that at least one supply hose of the functional unit, particularly of the valve, has a hose nozzle. Thus, a pressure-resistant connection with a hose nozzle on the functional unit may be combined with the connection described by a retaining flange, for example, on the drain side.

[0044] The present invention is described in more detail below based on embodiments, however, it is not limited to them. Other embodiments result from combining the features of individual or multiple claims with each other and / or with individual or multiple features of the embodiments.

[0065] Figure 20 is a partial representation of Figure 19.

[0066] Figures 1 to 6 and 9 show a first example of a modality and are described together below.

[0067] A sanitary accessory characterized by 1 has a water-conducting arrangement 2. This water-conducting arrangement 2 Petition 870260043322, dated 08 / 05 / 2026, page 16 / 54 10 / 15 comprises at least one sanitary functional unit 3, one connecting hose 4 and other connecting hoses 5.

[0068] Functional unit 3 has two inlets and one outlet, with the other connecting hoses 5 connected to the inlets and connecting hose 4 to the outlet.

[0069] A retaining lip 7 is formed at one end of the connecting hose 4 facing the functional unit 3.

[0070] Functional unit 3 has a functional body 8 and a support plate 9.

[0071] The other connecting hoses 5 have, in a known manner, respectively, a connecting piece 10, comprising a hose nozzle 13 and a crimping sleeve 14. The connecting pieces 10 are engaged, in a known manner, on the support plate 9 at the hose inlet 11.

[0072] The retaining lip 7 of the connecting hose 4 is engaged, without a separate connection, directly into a hose inlet 12 on the support plate 9.

[0073] The retaining flange 7 is produced here from the same material as the connecting hose 4 and is molded in one piece onto the connecting hose 4.

[0074] Connecting hose 4 consists of a thermoplastic material, which has been cut to length before assembly.

[0075] The retaining flange 7 was molded onto the connecting hose 4 using a heated drilling tool, in a thermoplastic form, from the hose material, such that the hose material was cast to form the retaining flange 7.

[0076] In Figure 4 it can be seen that the hose inlet is formed circumferentially closed so that the connecting hose 4 must be screwed through the hose inlet 12 Petition 870260043322, dated 08 / 05 / 2026, p. 17 / 54 11 / 15 during assembly and pulling to the retaining edge 7.

[0077] In the embodiment shown, the functional unit is formed as a valve 15 that can be actuated with an externally accessible actuating element 16, to control the flow of the other connecting hoses 5 into the connecting hose 4.

[0078] The connecting hose 4 is designed, therefore, as a drain hose 17 which is connected, on the low pressure side of the functional unit 3, in the manner described, with a retaining flange 7.

[0079] In Figures 5 and 6 it is possible to see that the lower part 18 of the retaining rim 7 is not flat, but has a structure.

[0080] through this structure an anchoring tie rod is formed that acts in the radial direction and prevents the retaining flange 7 from being pulled by the hose intake 12.

[0081] This risk may exist, for example, when the connecting hose 4 is heated by the hot water passing through it in such a way that dimensional stability is significantly reduced or is no longer provided.

[0082] The anchor tie rod 19 mentioned is formed, in the embodiment, by a rib 20 in the lower part 18, which engages in the corresponding groove 21 in a bearing surface 22 for the retaining edge 7 in the support plate 9.

[0083] Slot 21 thus forms an anchoring counter-tie 23, which causes locking and radial fixation of the retaining flange 7 in interaction with the anchor tie rod 19.

[0084] On an upper side 24 of the retaining rim 7, a sealing surface is formed that allows for axial sealing.

[0085] Since, in this embodiment, the connecting hose 4 is formed and used as a drain hose 17, the side Petition 870260043322, dated 08 / 05 / 2026, page 18 / 54 12 / 15 top 24 is the feed side 26.

[0086] In the functional body 8, a suitable counter-sealing surface 27 is formed with an axially sealed sealing ring 28. In the use position, the functional body 8 is pressed against the support plate 9 in such a way that, on the one hand, the anchoring tie rod 19 and the counter-anchoring tie rod 23 are held in the operating position and, on the other hand, the sealing ring 28 is compressed against the sealing surface 25 to cause the seal.

[0087] In the detailed representation according to Figure 2 it is also possible to recognize that at the end 6, an inlet opening 29 of the connecting hose 4 is formed which has a sharp edge 30 or a free edge of radii 31. By means of this, a smooth transition 32 to the functional body 8 is obtained without irregularities in the liquid flow wall leading to eddies.

[0088] By valve 15 this is a mixing cartridge 33, in which the connecting hose 4 is led as mixed water hose 34 to the water outlet 35 at the end of the outlet pipe 36.

[0089] Figures 7 and 8 show a variant of a combination of a connecting hose 4 with a support plate 9, as it could be installed in the water conduit arrangement 1, according to Figures 1 to 4, instead of the combination according to Figure 5.

[0090] Components and functional units that are functionally and / or constructively the same or identical to the previous exemplary embodiment are indicated by the same reference symbols and are not specifically described again. The embodiments for the previous exemplary embodiment therefore apply correspondingly to Figures 7 and 8.

[0091] In the example of modality according to Figures 7 and Petition 870260043322, dated 08 / 05 / 2026, p. 19 / 54 13 / 15 8, the anchor tie rod 19 and the counter-tie rod 23 are formed by a rib 20 on the bearing surface 22 and by a corresponding groove 21 on the lower part 18 of the retaining edge 7.

[0092] In other examples of the embodiment, other combinations of grooves and ribs or other means are used to create a positive union.

[0093] Figures 10 to 16 show another embodiment. Again, structurally and / or functionally to the previous embodiments, structurally identical or even identical components and functional units are designated with the same reference numbers and are not described separately again. The embodiments for Figures 1 to 9 therefore apply in accordance with Figures 10 to 16.

[0094] The embodiment shown in Figures 10 to 16 differs from the previous embodiment examples in that the intake of hose 12 is open laterally, as was already the case in the intakes of hose 11.

[0095] To secure the retaining edge 7 on all sides, a support disc 37, which forms the support surface 22, is placed on the hose inlet 12.

[0096] The support disc 37 is produced here from a non-thermoplastic material, for example, metal. In the embodiment, the support disc 37 is perforated or bent.

[0097] In other embodiments, the support disc 37 is produced from a non-metallic material, for example, from a synthetic material.

[0098] In other examples of modality, on the support surface 22, structures with sharp edges can be formed, for example, retaining grids, with which the support disc 37 can engage with the retaining edge 7. Petition 870260043322, dated 08 / 05 / 2026, p. 20 / 54 14 / 15

[0099] Figures 17 to 20 show another embodiment according to the present invention. Again, components and functional units that are functionally and / or constructively similar or identical to the previous embodiments are designated with the same functional units and are not described separately again. The embodiments for Figures 1 to 16 therefore apply in accordance with Figures 17 to 20.

[0100] The embodiment according to Figures 17 to 20 differs from the previous embodiments in that, at the feed end 6, no axially acting sealing surface 25 is formed, but rather a support 38. This support 38 forms a radially oriented sealing surface 25, which engages with a sealing ring 28, which is inserted into the lower part 39 of the functional body 8 and is radially compressed.

[0101] In the water-conducting arrangement 1, it is therefore suggested, according to the present invention, that at one end 6 of the connecting hose 4, a retaining flange 7 is formed which attaches behind a hose inlet 12 to engage the connecting hose 4.
