Use of a hose for the fluidic connection of an outlet piece to a valve on a sanitary fitting, fluidic arrangement and corresponding sanitary fitting

Abstract

According to the invention, in a fluidic arrangement (2) that can be mounted inside a sanitary fitting (1), it is proposed that a hose (5) connecting a spout (3) to a valve (4) be designed to be long enough that the hose (5) protrudes from an interior space (6) that spatially connects the valve (4) to the spout (3). This protruding section (45) of the hose (5) is fluidically connected to the valve (4) outside the interior space (6) (see Figure 1).

Description

[0001] The invention relates to a use of a hose for the fluidic connection of an outlet piece to a valve on a sanitary fitting, wherein the outlet piece can be firmly connected to the sanitary fitting.

[0002] The invention further relates to a fluidic arrangement for a sanitary fitting, comprising an outlet piece and a valve and a hose which fluidically connects the outlet piece to the valve, wherein the hose is fluidically connected to a point of the valve facing away from the outlet piece in the position of use of the valve.

[0003] Finally, the invention relates to a sanitary fitting.

[0004] It is known to use hoses in plumbing fixtures as described above. This allows the fluid flow to be functionally separated from the mechanical support on the plumbing fixture, thus creating greater design freedom for the plumbing fixture.

[0005] The invention is based on the object of simplifying the installation of a sanitary fitting.

[0006] To achieve this object, the features of claim 1 are provided according to the invention. In particular, when used as described above, the invention proposes that the hose extend between the outlet piece and its valve-side end in a section outside a housing of the sanitary fitting. Thus, a change in direction, for example, a curved loop or a deflection of the hose for returning to the valve, can be formed outside the confined space of the housing.

[0007] A further advantage is that a point where the hose can be connected to the valve can be arranged in such a way that a visual inspection is possible during assembly and / or that different hose lengths can be easily compensated.

[0008] Another advantage is that the valve can be installed first, before the hose needs to be fluidically connected to the valve. This can simplify valve installation, as it prevents previously connected hoses from resisting the valve's insertion and, for example, causing the valve to jam. This also prevents the hose from accidentally kinking when inserting the valve.

[0009] The invention thus unfolds its advantages particularly in the case of permanently installed or installable hoses, where the hose end at the outlet piece is not accessible from the outside during use.

[0010] It can be provided that the hose is arranged at least partially in an interior space of the sanitary fitting, which extends between the outlet piece and the valve. Thus, the hose can be arranged, for example, in an outlet pipe.

[0011] In this case, the hose can be led out of the interior and connected to the valve outside the interior. Another advantage is that the connection to the valve (typically a cartridge) can be made outside the confines of a spout. This can significantly simplify production. A catch funnel for (blind) insertion of the hose into the valve is unnecessary. Another advantage is that the installed hose can remain accessible from the outside. This allows for a taut or minimally twisted installation in the sanitary fitting. This can improve the service life of the hose and, in particular, ensure the long-term tightness of the connections.

[0012] Alternatively or additionally, the hose can be provided between the interior and its valve-side end in the section outside the housing of the sanitary fitting. The aforementioned section is thus located outside the interior and can be arranged so that it is easily accessible from the outside, particularly underneath a support structure for the sanitary fitting.

[0013] The connection of the hose to the valve can, for example, take place after the hose has been laid in the interior - particularly in the case of a one-piece hose - or before or at the same time as the hose has been laid in the interior - particularly in the case of a hose with two or more hose pieces.

[0014] In an advantageous embodiment, the interior space can be arranged in an outlet pipe of the sanitary fitting. Thus, the invention can be advantageously used in the particularly confined space of an outlet pipe.

[0015] In an advantageous embodiment, the hose can be provided with a greater length than the interior space can accommodate. This makes it easy to ensure that the hose protrudes from the interior space and remains accessible from the outside.

[0016] In an advantageous embodiment, the hose can be connected to the underside of the valve. This provides an easily accessible location for connection that is concealed during use. Excess hose can thus remain hidden from view.

[0017] In an advantageous embodiment, a valve-side section of the hose can be arranged so that it is accessible from outside the plumbing fixture. This allows the hose to be manipulated even after installation and connected to the valve under visual inspection, or fluidically connected to it - directly or indirectly.

[0018] In an advantageous embodiment, the hose can be provided with a deflection. This allows for space-saving hose routing, for example, past the valve and back to it.

[0019] In this case, the hose can be composed of two hose sections that are fluidically connected to each other via a connecting element. This allows for deflection without deforming the hose.

[0020] It is particularly advantageous if the connecting element is made from a single injection-molded part or assembled from several injection-molded parts. This enables simple production.

[0021] In an advantageous embodiment, the connecting element can be provided to create a fluidic change of direction between the hose sections. This avoids excessive curvature when the hose is routed outside the interior to the valve.

[0022] For example, the change in direction can be a reversal. This allows the hose sections to be placed close together.

[0023] In an advantageous embodiment, it can be provided that the connecting element is only mounted once at least one hose section, in particular both hose sections, have been mounted at their other ends. Thus, the hose sections can easily be brought to a uniform length – for example, by cutting them to length – before the connecting element is mounted.

[0024] To achieve the stated object, the features of the independent claim directed to a fluidic arrangement are provided alternatively or additionally according to the invention. In particular, in a fluidic arrangement of the type described above, the invention proposes that the hose has a deflection at a point spaced from its two ends. This avoids excessive bending, particularly when the hose is mounted on an underside of the valve. This can reduce the space required by the hose. This also creates a possibility of forming a connection between the hose and the valve outside the interior of a sanitary fitting—for example, outside a spout.

[0025] In an advantageous embodiment, the valve can be provided with a recess to accommodate the hose at a location spaced apart from its two ends. This provides a simple way to guide the hose past the valve and out of the interior of a sanitary fitting, in particular a spout, without requiring additional bulk in the area of ​​the valve.

[0026] In an advantageous embodiment, the hose can be connected to the underside of the valve. This allows for easy connection of the hose at a location that is already accessible for connecting additional hoses. This also allows for the hose to be routed as freely as possible away from the valve.

[0027] In an advantageous embodiment, the deflection can be achieved by means of a connecting element that fluidically connects two hose sections. This prevents the hose from kinking, for example, due to excessive bending stress.

[0028] In an advantageous embodiment, the connecting element can be provided with two hose receptacles and a connecting channel that fluidically connects them. Thus, the hose sections of the hose can be easily fluidically connected, in particular by inserting them into the hose receptacles.

[0029] In this case, the hose receptacles on the one hand and the connecting channel on the other can be arranged in such a way that they can be separated by a plane. This makes it easy to ensure that the two hose sections end on the same side of this plane. This replaces or avoids the very sharp bends in the hose that would otherwise be necessary.

[0030] In general, the hose forms a downward-hanging loop between its exit from the interior and the valve. It is advantageous to position the connecting element at the lowest point of the loop. This minimizes the use of lateral space.

[0031] In an advantageous embodiment, the hose receptacles can be provided so that they do not diverge in the insertion direction. This makes it easy to ensure that the inserted hose sections do not interfere with each other.

[0032] This can be achieved, for example, by arranging the hose receptacles parallel or converging. A parallel alignment of the hose receptacles has the advantage that the hose sections can be arranged particularly closely to one another. A converging arrangement has the advantage that injection molding can be particularly simple, since the respective tools for forming the hose receptacles converge toward one another, thus forming the connecting channel with their tips without the need for additional tools.

[0033] Alternatively or additionally, the hose receptacles can form an acute angle in at least one lateral projection. This makes it easy to ensure that the hose receptacles converge toward one another. For example, the hose receptacles can be aligned parallel to one another in another lateral projection or can also form a (possibly different) acute angle. The hose receptacles can meet or be skewed relative to one another. The hose receptacles can also converge toward one another and define an acute solid angle.

[0034] A lateral projection can be characterized, for example, by a projection direction running perpendicular to a longitudinal axis or direction of travel of at least one hose receptacle.

[0035] In an advantageous embodiment, the hose sections can be held firmly in place. This ensures a tight connection between the hose sections and the connecting element.

[0036] Alternatively or additionally, the hose sections can be secured in their hose receptacles with a self-locking spring element. This allows for easy assembly without the need for additional tools.

[0037] It can also be provided that one hose section is connected to one hose receptacle by a material bond, and another hose section is connected to another hose receptacle by means of a self-locking spring element. This can be determined depending on the material of the hose sections or other operating conditions and circumstances.

[0038] The hose sections can be connected to their hose receptacles, for example, by being plugged on, inserted, or attached. This can also be implemented in the same or different ways for the hose receptacles.

[0039] In an advantageous embodiment, the connecting element can be provided with a first part and a second part. Thus, a complex component can be assembled from individual, individually easy-to-manufacture parts.

[0040] In this case, the first part can form at least one hose receptacle. This is advantageous because additional components for forming the hose receptacle are dispensable.

[0041] It can also be provided that the second part forms at least one hose receptacle. This is advantageous because additional components for forming the hose receptacle are dispensable.

[0042] It is particularly advantageous if the first and second parts each form a hose receptacle. This allows the hose receptacles to be separated from each other. A fluid connection in the hose can be established, for example, after the parts have been assembled onto their respective hose sections.

[0043] Alternatively or additionally, a separating surface between the first part and the second part can be provided outside the hose receptacles. This is advantageous because the separating surface prevents any disruption or impairment of the hose receptacles—for example, during sealing. The separating surface can be flat or curved, for example—in particular, as a free surface. The separating surface can define an interface via which the first part can be connected or is connected to the second part.

[0044] In an advantageous embodiment, the first part forms both hose receptacles, and the second part forms a cover that defines the connecting channel. This allows the connecting channel to be easily manufactured using injection molding technology.

[0045] It is particularly advantageous if the first part forms the hose receptacles in one piece. This allows the hose receptacles to be firmly aligned with each other. Mechanical stresses between the hose sections can be easily absorbed.

[0046] Alternatively or additionally, the second part can be provided as a single piece to form the lid. This allows the second part to be easily used to complete a fluid path. Lids are generally easy to manufacture using injection molding.

[0047] In an advantageous embodiment, the first part can be provided with a recess that engages with the second part to form the connecting channel. This allows for the creation of more complex internal geometries.

[0048] In this case, the formation can be arranged at a distance from a sealing flange connecting the first part and the second part. A separate sealing of a complex formation can therefore be omitted.

[0049] Alternatively or additionally, the connecting channel can be designed to have a consistent cross-section along its length. This reduces flow resistance and turbulence, or even eliminates it entirely.

[0050] In an advantageous embodiment, the first part and the second part can jointly form a section of the connecting channel with a round cross-section. This allows for an internal geometry that is particularly favorable for flow with as little loss as possible.

[0051] Alternatively or additionally, the first part and the second part can be provided together to form a section of the connecting channel with a consistent cross-section. This allows a consistent cross-section of the connecting channel to be easily created using injection-molded parts. The resulting longitudinal division avoids holes that would otherwise be laborious to create in the injection mold.

[0052] In an advantageous embodiment, the first part and the second part can be fluidically connected by an axial seal. An axial seal has the advantage that a connection can be established by a plug-in movement transverse to a flow direction. Thus, guide means for the plug-in movement can be designed to absorb axial forces. This relieves the load on the fluidic connection. The risk of a fluidic connection being released by internal pressure can thus be reduced because the opening movement is oriented transversely to the direction of the force resulting from the internal pressure.

[0053] In an advantageous embodiment, the hose receptacles of the connecting element can be designed without longitudinal burrs. This makes it particularly easy to achieve a tight seal in the hose receptacles. For example, this can be achieved by having a tool parting line running outside the hose receptacles.

[0054] To achieve the stated object and as a preferred application of the invention, in a sanitary fitting, wherein a fluidic arrangement has an outlet piece and a valve and a hose that fluidically connects the outlet piece to the valve, wherein the outlet piece is firmly connected to the sanitary fitting, it is provided that the hose extends between the outlet piece and its valve-side end in a section outside a housing of the sanitary fitting. This allows the hose to be returned to the valve outside the sanitary fitting. Any obstruction to the hose routing inside the housing can thus be reduced.

[0055] In this case, the fluidic arrangement can be designed, for example, according to the invention, in particular as described above and / or according to one of the claims directed to a fluidic arrangement.

[0056] Alternatively or additionally, the sanitary fitting is designed for a use according to the invention, in particular as described above and / or according to one of the claims directed to a use. Thus, the advantages of the invention can be utilized in a sanitary fitting, in particular, the interior space being arranged in an outlet pipe of the sanitary fitting.

[0057] In this case, the hose can be connected to the valve outside the interior. The hose can thus remain accessible for direct or indirect connection to the valve.

[0058] A particularly advantageous use according to the invention, in particular as described above and / or according to one of the claims directed to a use, is one in which a fluidic arrangement according to the invention, in particular as described above and / or according to one of the claims directed to a fluidic arrangement, and / or a fluidic arrangement is used as part of the previously described sanitary fitting. The aforementioned individual aspects can thus be advantageously combined.

[0059] The invention will now be described in more detail using exemplary embodiments, but is not limited to these exemplary embodiments. Further exemplary embodiments arise from combining the features of individual or multiple claims with one another and / or with individual or multiple features of the exemplary embodiments.

[0061] A sanitary fitting designated as a whole with 1 according to Figure 1 has a fluidic arrangement for water flow 2.

[0062] The fluidic arrangement 2 has an outlet piece 3 and a valve 4.

[0063] The outlet piece 3 is fluidically connected to the valve 4 via a hose 5.

[0064] For example, a jet regulator and / or jet former known per se can be arranged or formed in the outlet piece 3.

[0065] The hose 5 is arranged in an interior space 6 of the sanitary fitting 1, which is formed by an outlet pipe 7.

[0066] The interior space 6 extends between the outlet piece 3 and the valve 4 and is limited by them.

[0067] The outlet pipe 7 thus establishes a mechanical connection between the outlet piece 3 and the valve 4.

[0068] To establish the fluidic connection, the hose 5 is connected with its outlet end 8 to the outlet piece 3.

[0069] With its valve-side end 9, the hose 5 is led out of the interior 6.

[0070] The hose 5 is thus fluidically connected to the valve 4 at a point 10 which, in the mounted position of use, faces away from the outlet piece 3 and the interior 6.

[0071] It can thus be said that the hose 5 is guided past the valve 4. For this purpose, the valve 4 has a recess 11 which at least partially accommodates the hose 5 at a point 13 between the ends 8, 9.

[0072] The hose 5 is fluidically connected to the underside 14 of the valve 4, to which a cold water hose 15 and a hot water hose 16 are also connected (in a manner known per se).

[0073] At a point 17 between the ends 8, 9, more precisely in the exemplary embodiment between the point 13 and the valve-side end 9, i.e. outside the interior space 6, a deflection 18 is formed.

[0074] This deflection 18 divides the hose 5 into two hose pieces 19, 20.

[0075] The deflection 18 causes the flow direction between the valve-side hose section 20 and the outlet-side hose section 19 to change by more than 90°.

[0076] For this purpose, the deflection 18 is effected by means of a connecting element 21, which fluidically connects the valve-side hose section 20 with the outlet-side hose section 19.

[0077] For fluidic connection, a hose receptacle 22 for the outlet-side hose section 19 and a hose receptacle 23 for the valve-side hose section 20 are formed on the connecting element 21.

[0078] These hose holders 22, 23 are connected by a connecting channel 24 (cf. e.g. Fig. 8 to 10 ) are fluidically connected to one another so that water can flow from the valve-side hose section 20 into the outlet-side hose section 19.

[0079] The hose 5 thus forms a loop 46 between its outlet 47 from the interior 6 and the valve 4. The deflection 18 is formed at the lowest point 17 of the loop 46.

[0080] Figure 2shows a further sanitary fitting 1 with a fluidic arrangement 2 according to the invention. Components and functional units that are functionally and / or structurally similar or identical to the preceding embodiment are designated by the same reference numerals and are not described separately again. Figure 1 are therefore considered Figure 2 accordingly.

[0081] The embodiment according to Figure 2 differs from the preceding embodiment in that the hose 5 is fastened at its valve-side end 9 with a crimp sleeve 25 on a hose nipple (not shown in more detail), which is known per se, while the hose 5 in Figure 1 is plugged directly into a corresponding hose receptacle (not shown) on the valve 4.

[0082] The Figures 3 to 6show the assembly steps for assembling the fluidic arrangement 2 using the sanitary fitting 1. Components and functional units that are structurally and / or functionally similar or identical to the preceding embodiments are designated by the same reference numerals and are not described separately again. Figures 1 and 2 are therefore considered to be Figures 3 to 6 accordingly.

[0083] It is evident that in a first step ( Figure 3 ) first, the outlet-side hose section 19, to which the outlet piece 3 may already be attached, is introduced from the outside via the interior space 6 in the outlet pipe 7 into the vertically oriented space 26 below the valve 4. It can also be seen that the valve-side hose section 20 - in which an adapter piece 27 may already be connected to the valve-side end 9, is introduced from the outside (above) into the space 26.

[0084] In a next step ( Figure 4) the cold water hose 15 and the hot water hose 16 are led from below through the space 26 to the adapter piece 27 and connected to it.

[0085] Afterward ( Figure 5 ) The valve 4 is assembled from a base body 28, which accommodates the valve mechanism in a conventional manner, and the adapter piece 27 and mounted on the sanitary fitting 1. This step can also be performed before the second assembly step.

[0086] The outlet-side hose section 19 and the valve-side hose section 20 can now be cut to a common length with which they protrude beyond the space 26.

[0087] For this purpose, the outlet piece 3 is already moved into its position of use, so that the outlet-side hose piece 19 no longer moves.

[0088] Finally ( Figure 6) the connecting element 21 is placed on the hose pieces 19, 20 or connected to them in order to establish a fluidic connection between the valve 4 and the outlet piece 3 and to effect a deflection 18 of the water flow at the transition between the valve-side hose piece 20 and the outlet-side hose piece 19.

[0089] Figure 7 shows, as an example, three connecting elements 21, which instead of the general functional block, for example, in the Figures 1 and 2 can be used. A three-dimensional oblique view and a side view are shown. Components and functional units that are functionally and / or structurally similar or identical to the previous embodiments are designated by the same reference numerals and are not described separately again.

[0090] It can be seen that the hose receptacles 22, 23 are arranged relative to each other in such a way that a solid angle of less than 90°, particularly in the variants in the middle and on the right (parallel hose receptacles 22, 23) defines a solid angle of 0°.

[0091] Figure 8 shows the left connecting element 21 from Figure 7 additionally in an axial section.

[0092] It is evident that a plane 29, perpendicular to the plane of the drawing, can be found, which separates the hose receptacles 22, 23 on the one hand and the connecting channel 24 on the other. This prevents the inserted hose section 19, 20 from partially or completely closing the connecting channel 24.

[0093] In other words, the hose receptacles 22, 23 with their openings are located in a half-space which does not contain the connecting channel 24, at least in its deflecting region 30.

[0094] In the embodiment according to Figure 8 the hose section 19, 20, for example the valve-side hose section 20 is inserted into the corresponding hose receptacle 23 and secured with a self-locking spring element 31

[0095] The other hose receptacle 23 can be designed in the same way or - as shown here by way of example - can be designed for the material-locking connection or casting of the outlet-side hose piece 19.

[0096] In further embodiments, both hose receptacles 22, 23 can be equipped with a self-locking spring element 31.

[0097] Figure 9 shows an alternative to the embodiment according to Figure 8 . Here, material-to-material connections in both hose receptacles 22, 23 are shown.

[0098] It is advantageous for both designs if the hose receptacles are dimensioned in such a way that an inserted piece of hose 19, 20 does not leave a step at the transition.

[0099] In all other respects, the explanations to the Figures 1 to 8 accordingly.

[0100] Figure 10 shows a further connecting element 21 as an alternative to the connecting element 21 according to Figure 8 .

[0101] Again, both hose receptacles 22, 23 are designed for material-to-material connection, for example laser welding, gluing, etc.

[0102] The variant is characterized by increased stability, which is achieved through thicker walls and a reinforcement gusset 32.

[0103] In the embodiments according to the Figures 8 to 10The hose receptacles 22, 23 each have a longitudinal axis 33. The longitudinal axes 33 of the two hose receptacles 22, 23 meet at one point and thus form an acute angle. It can therefore be said that the connecting elements 21 of the Figures 8 to 10 can be inscribed in an acute solid angle.

[0104] In further embodiments, these longitudinal axes 33 do not meet, but are skewed to each other. However, in these embodiments, the same image is obtained in lateral projection as in the Figures 8 to 10 , so that it can be said that the hose receptacles 22, 23 also enclose an acute angle in at least one lateral projection, namely the projection onto the plane of the drawing in the figures shown, in these embodiments.

[0105] Furthermore, the comments on the Figures 1 to 9 .

[0106] The examples of implementation according to the Figures 8 to 10 have in common that the connecting element 21 can be manufactured as a single injection-molded part. This is aided by the angled alignment of the hose receptacles 22, 23 relative to each other, which enables undercut-free production in the area of ​​the connecting channel 24.

[0107] The Figures 11 to 14 show another example of a connecting element 21. This connecting element 21 is in Figure 7 shown in the middle. Components and functional units that are functionally and / or structurally similar or identical to the previous embodiments are again designated by the same reference numerals and are not described separately again. The explanations regarding the Figures 1 to 10 are therefore considered to be Figures 11 to 14 accordingly.

[0108] The embodiment differs from the previous embodiments in that the connecting element 21 comprises a first part 35 and a second part 36, which together provide a fluid guide.

[0109] Here, two hose receptacles 22, 23 are formed on the first part 35, which are oriented parallel to each other in this example. Angled variants similar to Figures 8 to 10 possible.

[0110] The second part 36 is separated from the first part 35 by a separating surface 37, which forms a sealing flange 38. The sealing flange 38 is closed by a material-to-material connection.

[0111] This separating surface 37 runs outside the hose receptacles 22, 23. The second part 36 forms a cover 39, which limits the connecting channel 24 to the outside.

[0112] Here, a recess 40 is formed on the first part 35, protruding from the separating surface 37 and engaging the second part 36, which defines one half of a circumference in the cross-section of the connecting channel 24. The other half is defined here by the cover 39.

[0113] In this way, it can be achieved that the cross-section of the connecting channel 24 remains constant in its course and thus the cross-sectional area does not form a constriction compared to the hose pieces 19, 20.

[0114] This is achieved by a doubly arched or doubly curved surface 48 of the formation 40 in the manner of a saddle point (cf. Figs. 14 and 15 ).

[0115] In Figure 15It is also clear that the protrusion 40 is not involved in sealing the connecting channel 24, but merely serves to guide the flow. The circumferential sealing flange 38 completely seals the space 26, in which the protrusion 40 engages, from the outside.

[0116] The Figures 16 and 17 show a variant of the embodiment according to Figures 11 to 15 , where instead of Figure 14 shown self-locking spring element 31, a material connection is produced between the hose receptacles 22, 23 and the hose pieces 19, 20, for example by laser welding or other welding.

[0117] Furthermore, the statements regarding the preceding embodiments apply to the Figures 15 to 17 accordingly.

[0118] The Figures 18 and 19 show a further connecting element 21, for example for use in Figure 1 or 2 .

[0119] Here, the first part 35 and the second part 36 are connected to each other with a film hinge 41 and can be manufactured in a single injection-molding process. The film hinge 41 enables the alignment of the parts 35, 36 with respect to each other.

[0120] In all other respects, the statements regarding the Figures 11 to 17 accordingly.

[0121] The Figures 20 to 23 show a further embodiment of a connecting element 21. Components and functional units that are functionally and / or structurally similar or identical to the preceding embodiments are designated by the same reference numerals and are not described separately again. Figures 1 to 19 are therefore considered to be Figures 20 to 23 accordingly.

[0122] The connecting element 21 according to the Figures 20 to 23differs from the preceding connecting elements 21 in that the separating surface 37 is not flat, but has a laterally curved profile. This prevents the separating surface 37, which is arranged in an axial plane, from running into the hose receptacles 22, 23.

[0123] The hose receptacles 22, 23 are therefore - like the other hose receptacles - designed without longitudinal burrs and thus allow a particularly good fit to the inserted hose pieces 19, 20.

[0124] The second part 36 is aligned with the first part 35 using a positioning aid 50. The two parts 35, 36 are then joined together.

[0125] The two parts 35, 36 each define half a circumference in the cross-section of the connecting channel 24, as can be seen from Figure 20 is evident.

[0126] The Figures 24 and 25show a further connecting element 21. In this case, the cover-shaped second part 36 is essentially flat or planar, so that the connecting channel 24 has a dead space 42 which is provided by a cross-sectional widening.

[0127] The Figures 26 to 29 show detailed views of the connecting element 21 from Figure 7 , right figure.

[0128] An axial seal 44 is formed on the separating surface 37, which now runs between the hose receptacles 22, 23.
