EP4229245B1 - 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 - Google Patents

Description

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

The invention further relates to a fluidic arrangement for a sanitary fitting, with 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 on the valve facing away from the outlet piece in the position of use of the valve.

Finally, the invention relates to a sanitary fitting.

It is known to use hoses in sanitary fittings in accordance with the use described above. This makes it possible to functionally separate the fluid guide from the mechanical support on the sanitary fitting and thus create greater design freedom on the sanitary fitting.

From the WO 2017/123087 A1 A mixer tap for dispensing water is known. From the DE 10 2013 020586 A1 A hose coupling for connecting a flexible hose line with an adjacent line section is known. US 2017/183846 A1 A faucet assembly is known which comprises a faucet body with a fastening axis in a direction in which the faucet body protrudes from a fastening point. From the EP 0 432 553 A1 A valve housing is known which has a fixed housing part which is surrounded by a casing element which can be pivoted about an axis. WO 2009/143352 A1 is a deflection arrangement for use with a faucet assembly having a diverter valve attached to an inlet end of a spray tube and releasably received in a connector.

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

To achieve this object, the features of claim 14 are provided according to the invention. In particular, when used as described above, the invention proposes 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 a change in direction, for example a bent loop or a deflection of the hose for return to the valve outside the confined space.

space available in the housing. A further advantage is that a point at which 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.

Another advantage is that it is possible to install the valve first, before the hose has to be fluidically connected to the valve. This can simplify the installation of the valve, as it avoids hoses that are already connected offering resistance to the insertion of the valve and thus causing the valve to jam, for example. This also avoids the hose becoming accidentally kinked when the valve is inserted.

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.

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. The hose can thus be arranged in an outlet pipe, for example.

It can be provided that the hose is 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 confined space of an outlet pipe. This can significantly speed up production. simplify. A funnel for (blind) insertion of the hose into the valve is not required. Another advantage is that the installed hose can remain accessible from the outside. This makes it possible to install it tightly or with minimal twisting in the sanitary fitting. This can improve the service life of the hose and in particular the permanent tightness of the connections.

Alternatively or additionally, it can be provided that the hose extends between the interior and its valve-side end in the section outside the housing of the sanitary fitting. The section already mentioned is therefore outside the interior and can be arranged so that it is easily accessible from the outside and in particular below a support structure for the sanitary fitting.

The connection of the hose to the valve can, for example, be made after the hose has been laid in the interior or - particularly in the case of a hose with two or more hose sections - before or when the hose is laid in the interior.

In an advantageous embodiment, it can be provided that the interior is arranged in an outlet pipe of the sanitary fitting. The invention can thus be used advantageously in the particularly confined space conditions of an outlet pipe.

In an advantageous embodiment, it can be provided that the hose has a greater length than can be accommodated by the interior. This makes it easy to ensure that the hose protrudes from the interior and remains accessible from the outside.

In an advantageous embodiment, the hose can be connected to the underside of the valve. This means that an easily accessible location that is concealed during use can be used for connection. Excess hose can therefore remain hidden from the viewer.

In an advantageous embodiment, it can be provided that a valve-side section of the hose is arranged so that it is accessible from outside the sanitary fitting. This means that the hose can be manipulated even after it has been laid and connected to the valve under visual inspection or - directly or indirectly - fluidically connected to it.

According to the invention, the hose is provided with a deflection. This allows a space-saving hose routing, for example past the valve and back to it.

The idea is that the hose is made up of two hose pieces that are fluidically connected to one another via a connecting element. This allows the hose to be redirected without deforming.

It is particularly advantageous if the connecting element is made from an injection-molded part or is composed of several injection-molded parts. This enables simple production.

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

For example, the change in orientation can be a reversal of direction. This means that the hose sections can be placed close to each other.

In an advantageous embodiment, it can be provided that the connecting element is only mounted when at least one piece of hose, in particular both pieces of hose, are mounted with their other ends. The pieces of hose can thus be easily brought to a uniform length - for example by cutting them to the appropriate length - before the connecting element is mounted.

To achieve the stated object, the features of claim 1 directed to a fluidic arrangement are also provided according to the invention. In particular, in a fluidic arrangement of the type described at the outset, the invention proposes that the hose has a deflection at a point spaced apart from its two ends. This avoids excessive bending, particularly when the hose is mounted on an underside of the valve. This can reduce the amount of space taken up by the hose. This also creates the possibility of forming a connection between the hose and the valve outside the interior of a sanitary fitting - for example outside an outlet pipe.

In an advantageous embodiment, the valve can have a recess to accommodate the hose at a further location spaced from its two ends. This creates a simple possibility of leading the hose past the valve out of an interior of a sanitary fitting, in particular an outlet pipe, without this having to be done in the area of the valve. must be applied additionally.

In an advantageous embodiment, the hose can be connected to the underside of the valve. This makes it easy to connect the hose to a location that is already accessible for connecting other hoses. This also makes it possible to route the hose as freely as possible away from the valve.

According to the invention, the deflection is produced by means of a connecting element that fluidically connects two hose pieces. This makes it possible to avoid kinking of the hose - for example due to excessive bending stress.

According to the invention, the connecting element has two hose receptacles and a connecting channel that fluidically connects them. The hose sections of the hose can thus be easily fluidically connected, in particular by inserting them into the hose receptacles.

It can be provided that the hose receptacles on the one hand and the connecting channel on the other hand are 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 very strong bends in the hose that would otherwise be necessary.

In general, it can be said that the hose forms a downward hanging loop between its exit from the interior and the valve. It is advantageous if the connecting element is located at the lowest point of the loop. This means that as little lateral installation space as possible is required. be consumed.

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

This can be achieved, for example, by having the hose holders run parallel or converge towards one another. A parallel alignment of the hose holders has the advantage that the hose pieces can be arranged particularly close to one another. An arrangement that converges towards one another has the advantage that injection molding can be particularly easy, since the respective tools for forming the hose holders converge towards one another and can thus form the connecting channel with their tips without additional tools.

Alternatively or additionally, it can be provided that the hose receptacles enclose an acute angle in at least one lateral projection. This makes it easy to ensure that the hose receptacles run towards each other. For example, the hose receptacles can be aligned parallel to each other in another lateral projection or also enclose an acute angle (possibly different). The hose receptacles can meet or be skewed to each other. The hose receptacles can also run towards each other and describe an acute solid angle.

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

In an advantageous embodiment, it can be provided that the hose pieces are held in a materially bonded manner. This enables a tight connection of the hose pieces to the connecting element.

Alternatively or additionally, the hose sections can be held in their hose holder with a self-locking spring element. This makes assembly easy to carry out without any additional tools.

It can also be provided that one hose section is connected to one hose receptacle by means of 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.

The hose pieces can be connected to their hose holders, for example, by being plugged on, inserted or attached. This can also be done in the same or different ways for the hose holders.

According to the invention, the connecting element has a first part and a second part. This allows a complex component to be assembled from individual parts, each of which is easy to manufacture.

In this case, it can be provided that the first part forms at least one hose holder. The advantage here is that further components for forming the hose holder are not necessary.

It can also be provided that the second part forms at least one hose holder. The advantage here is that further components for forming the hose holder are not required.

It is particularly advantageous if the first part and the second part each form a hose holder. This means that the hose holders can be separated from one another. A fluidic connection in the hose can be established, for example, after the parts have been mounted on their respective hose sections.

Alternatively or additionally, it can be provided that a separating surface between the first part and the second part runs outside the hose receptacles. The advantage here is that any disruption or impairment of the hose receptacles - for example during sealing - can be avoided by the separating surface. 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.

In an advantageous embodiment, it can be provided that the first part forms both hose receptacles and the second part forms a cover that delimits the connecting channel. The connecting channel can thus be easily manufactured using injection molding technology.

It is particularly advantageous if the first part forms the hose holders in one piece. This means that the hose holders can be firmly aligned with each other. Mechanical stresses between the hose pieces can be easily absorbed.

Alternatively or additionally, it may be provided that the second part forms the lid in one piece. The second part can therefore be used in a simple manner to complete a fluid path. Lids are usually easy to manufacture using injection molding.

According to the invention, the first part has a shape that engages in the second part to form the connecting channel. This allows more complex internal geometries to be formed.

In this case, it can be provided that the formation is 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.

Alternatively or additionally, the connecting channel can have a constant cross-section along its course. This means that flow resistance can be reduced and turbulence can be reduced or even completely avoided.

In an advantageous embodiment, it can be provided that the first part and the second part together form a section of the connecting channel with a round cross-section. This makes it possible to form an internal geometry that is particularly favorable for flow that is as loss-free as possible.

Alternatively or additionally, it can be provided that the first part and the second part together form a section of the connecting channel with a constant cross-section. This means that a constant cross-section of the connecting channel can be easily formed using injection-molded parts. The resulting longitudinal division avoids holes that would have to be laboriously created in the injection molding tool.

In an advantageous embodiment, it can be provided that the first part and the second part are fluidically connected with 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. Guide means for the plug-in movement can thus be designed to absorb axial forces. This relieves the fluidic connection. The risk of a fluidic connection being released by the internal pressure can thus be reduced because the opening movement is aligned transversely to the direction of the force of the load resulting from the internal pressure.

In an advantageous embodiment, it can be provided that the hose receptacles of the connecting element are 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 run outside the hose receptacles.

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 makes it possible to return the hose outside the sanitary fitting to the valve. Any obstruction to the hose guide inside the housing can thus be reduced.

In this case, the fluidic arrangement can be designed according to the invention, in particular as described above and/or according to one of the methods directed to a fluidic arrangement. demands, be trained.

Alternatively or additionally, the sanitary fitting is designed to be used according to the invention, in particular as described above and/or according to one of the claims directed to a use. The advantages of the invention can thus be used in a sanitary fitting, in particular where the interior can be arranged in an outlet pipe of the sanitary fitting.

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.

A use according to the invention, in particular as described above and/or according to one of the claims directed to a use, 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 sanitary fitting described above, is particularly favorable. The individual aspects mentioned can thus be advantageously combined.

The invention will now be described in more detail using embodiments, but is not limited to these embodiments. Further embodiments arise by combining the features of individual or multiple protection claims with one another, as specified in the appended claims.

A sanitary fitting designated as a whole with 1 according to Figure 1 has a fluidic arrangement for water guidance 2.

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

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

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

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

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

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

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

The hose 5 is led out of the interior 6 with its valve-side end 9.

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.

It can therefore 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 further point 13 between the ends 8, 9.

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).

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

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

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°.

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.

For the 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.

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.

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.

Figure 2 shows 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 with the same reference numerals and are not described separately again. The explanations for Figure 1 are therefore considered Figure 2 accordingly.

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

The Figures 3 to 6 show 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 with the same reference numerals and are not described separately again. The explanations for the Figures 1 and 2 are therefore among the Figures 3 to 6 accordingly.

It is clear that in a first step ( Figure 3 ) first the outlet-side hose section 19, to which the outlet piece 3 can already be attached, is introduced from the outside via the interior 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 can already be connected to the valve-side end 9, is introduced from the outside (above) into the space 26.

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.

Afterward ( Figure 5 ), the valve 4 is assembled from a base body 28, which accommodates the valve mechanism in a manner known per se, and the adapter piece 27 and mounted on the sanitary fitting 1. This step can also be carried out before the second assembly step.

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.

For this purpose, the outlet piece 3 is already brought into its position of use, so that the outlet-side Hose section 19 does not move any further.

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 cause a deflection 18 of the water flow at the transition between the valve-side hose piece 20 and the outlet-side hose piece 19.

Figure 7 shows three connecting elements 21 as an example to explain the technical background, 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 embodiments are designated with the same reference numerals and are not described separately again.

It can be seen that the hose receptacles 22, 23 are arranged relative to each other such 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°.

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

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

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.

In the example according to Figure 8 the hose piece 19, 20, for example the valve-side hose piece 20, is inserted into the corresponding hose receptacle 23 and secured in a tension-resistant manner with a self-locking spring element 31.

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.

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

Figure 9 shows an alternative to the example according to Figure 8 Here, material-locking connections in both hose receptacles 22, 23 are shown.

In both designs, it is advantageous if the hose holders are dimensioned in such a way that an inserted hose piece 19, 20 does not leave a step at the transition.

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

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

Again, both hose receptacles 22, 23 are designed for material-locking connection, for example laser welding, gluing, etc.

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

In the examples according to the Figures 8 to 10 The hose holders 22, 23 each have a longitudinal axis 33. The longitudinal axes 33 of the two hose holders 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.

In other examples, these longitudinal axes 33 do not meet, but are skewed to each other. In these examples, however, 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 in these examples enclose an acute angle in at least one lateral projection, namely the projection onto the drawing plane in the figures shown.

Furthermore, the comments on the Figures 1 to 9 .

The examples after the Figures 8 to 10 have in common that the connecting element 21 can be manufactured as a single piece as an injection-molded part. This is aided by the oblique alignment of the hose holders 22, 23 to one another, which in the area of the connecting channel 24 creates a undercut-free production is possible.

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 with the same reference numerals and are not described separately again. The explanations for the Figures 1 to 10 are therefore among the Figures 11 to 14 accordingly.

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.

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

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-locking connection.

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.

In this case, a formation 40 is formed on the first part 35, which protrudes from the separating surface 37 and engages into the second part 36, which forms one half of a circumference in Cross-section of the connecting channel 24. The other half is defined here by the cover 39.

In this way, it can be ensured 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.

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

In Figure 15 It is still clear that the formation 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 formation 40 engages from the outside.

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.

Furthermore, the statements on the previous embodiments apply to the Figures 15 to 17 accordingly.

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

Here, the first part 35 and the second part 36 are connected to one another with a film hinge 41 and can be manufactured in an injection molding process. The film hinge 41 enables the parts 35, 36 to be aligned with one another.

In all other respects, the statements on the Figures 11 to 17 accordingly.

The Figures 20 to 23 show a further example of a connecting element 21 to explain the technical background. Components and functional units that are functionally and/or structurally similar or identical to the preceding embodiments are designated with the same reference numerals and are not described separately again. The explanations for the Figures 1 to 19 are therefore among the Figures 20 to 23 accordingly.

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

The hose receptacles 22, 23 are therefore - like the other hose receptacles - designed to be free of longitudinal burrs and thus allow a particularly good fit to the inserted hose pieces 19, 20.

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 in a material-tight manner.

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.

The Figures 24 and 25 show a further connecting element 21. In this case, the lid-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 expansion.

The Figures 26 to 29 show detailed views of the connecting element 21 from Figure 7 , right image.

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

The first part 35 and the second part 36 can be moved against each other in the sealing plane in order to achieve a positive fit.

This variant also enables the production of two individual parts that can be demoulded and therefore manufactured using injection moulding technology.

Overall, it can be said that the formation 40 is designed and arranged such that the connecting channel 24 has a constant cross-section at least in the section 43.

According to the invention, in a fluidic arrangement 2 that can be mounted inside a sanitary fitting 1, it is proposed to design a hose 5 that connects an outlet piece 3 to a valve 4 so long that the hose 5 protrudes from an interior 6 that spatially connects the valve 4 to the outlet piece 3. This protruding section of the hose 5 is fluidically connected to the valve 4 outside the interior 6.
