Description

Arrangement for guiding water

Technical Field

The invention relates to a water-guiding arrangement comprising a functional unit and at least one connecting hose.

Background

Such water-guiding arrangements are known and are incorporated, for example, in sanitary fittings. The connecting hose is often used to separate the function of the water guidance of the functional unit, for example a valve or a water outlet, from the function of the mechanical retention of the functional unit on the sanitary fitting. This often results in the fluid connection of the connecting hose to the functional unit being provided hidden in the sanitary fitting in the use position.

Disclosure of Invention

The object of the invention is to provide a simple, fluid-tight connection in a water-conducting arrangement.

In order to solve the task, according to an advantageous feature of the invention. In particular, in the case of a water-guiding arrangement of the type mentioned at the outset, it is therefore proposed according to the invention that an integrally formed retaining flange is formed in one piece at the end of the connecting hose facing the functional unit and is caught on the hose receptacle of the valve. The hose connection to the connecting hose can therefore be dispensed with. This simplifies the establishment of the fluid connection. When the hose connection is no longer required, the net internal cross-section can be selected larger at a constant external dimension. This is advantageous for a flow resistance which is as low as possible.

The functional unit may be, for example, a valve or a water outlet. The invention can therefore advantageously be used in functional units which are arranged in narrow spaces.

For example, the connection hose may be an inlet hose. The invention can thus also be used in connection hoses with relatively high operating pressures. It can be provided here, for example, that the connection hose is a cold water hose. This can positively affect the long-term stability of the fluid connection.

For example, the connection hose may also be a discharge hose. The invention is used here in that the operating pressure on the outlet side of the functional unit is often significantly lower than the operating pressure on the inlet side due to the pressure drop on the functional unit.

In one embodiment of the invention, it can be provided that the connecting hose is produced from a thermoplastic material. The retaining flange can thus be formed particularly simply.

In one embodiment of the invention, it can be provided that the holding flange is formed by thermoplastic molding. In this case, the connecting hose can advantageously be produced from extruded material. The holding flange may in this case be shaped, for example, after shearing the connecting hose.

In one embodiment of the invention, the hose receptacle can be open laterally. So that the connection hose does not have to be threaded.

In one embodiment of the invention, the hose receptacle can be designed to be closed around. Thus, the holding flange can be supported along the entire circumference.

In one embodiment of the invention, it can be provided that the radially acting pull anchor is formed on the retaining flange. Thus, an anti-pull-out device may be provided. This is particularly advantageous in the case of connection hoses which partially lose their form stability by heating with flowing warm water.

In this case, it can be provided, for example, that the tension anchor is formed as a groove or a rib. A form-locking connection between the holding flange and the hose receptacle can thus be established with a simple mechanism. The hose receptacle can be provided with a corresponding shape, for example, in particular on the support surface.

The groove or rib may be formed, for example, circumferentially in order to hold the holding flange on all sides.

In one embodiment of the invention, it can be provided that the holding flange presses onto a bearing surface on the hose receptacle. Thus preventing the retaining flange from sliding out. In this case, it is particularly advantageous if the pull anchor already described is formed on the retaining flange. By means of the pressing force, it is possible to achieve a form-locking of the pull-in anchor without undesired detachment even in the case of hot water temperatures.

In one embodiment of the invention, it can be provided that one of the support surfaces, for example the already mentioned support surface, on the hose receptacle is formed in correspondence with the retaining flange. A form-locking can thus be established.

It can be provided here, for example, that a radially acting mating pull anchor is formed in this way. By means of the engagement of the pull anchor and the mating pull anchor, a particularly secure holding of the holding flange can be achieved.

This can be achieved, for example, by a form-locking design between the hose receptacle and the holding flange.

The form-locking simple design is provided by at least one, preferably circumferential, rib which engages into the groove. Thereby enabling additional sealing to be achieved.

The at least one rib may be formed here, for example, on the support surface and/or on the retaining flange.

In one embodiment of the invention, it can be provided that the hose receptacle has a circumferential support disk, against which the retaining flange rests. In this case, it is advantageous if, independently of the design of the functional unit, the holding flange can be supported on all sides, in particular if the hose receptacle is open laterally.

The support disk is preferably designed to be removable. This may simplify disassembly. Different materials may also be selected for the support disc and for the carrier plate supporting the support disc.

For example, it can be provided that the support disk is formed as a stamping and/or a bending piece. The support disk can thus be produced, for example, from metal, while the already mentioned carrier plate of the functional unit can be produced from plastic.

For example, it can be provided that the support disk is embodied as a die casting, in particular as a zinc die casting. Thus, alternative materials may be used.

Alternatively or additionally, the support disk may be formed as a plastic part. The plastic part may for example be thermoplastic, in order to allow for a simple manufacture.

Alternatively or additionally, provision may be made for the bearing surface for the holding flange to be embodied as a sharp edge, in particular as already described. These sharp-edged structures can be embedded in the holding flange in order to hold the structures in a form-fitting manner. This can be achieved particularly simply if the support disk is a stamping and/or bending part and/or die-cast part, for example of metal, in particular a zinc die-cast part.

The sharp-edged structure described here can, for example, have at least one holding claw. Thus, a structure which can be produced particularly simply is described.

In one embodiment of the invention, it can be provided that a sealing surface is formed at the end of the connecting tube. In this case, the sealing function can advantageously be integrated into the holding flange. Other sealing mechanisms may be dispensed with. The connecting hose can thus be produced from a single component, since a sealing ring or other sealing means can be provided on the functional unit.

The sealing surface can be formed here, for example, circumferentially. Sealing on all sides can thus be achieved.

It may be provided that the sealing surface acts axially. The pressing force onto the holding flange, in particular the pressing force described above, can thus be used for sealing.

Alternatively or additionally, it may be provided that the sealing surface acts radially. An arrangement is described, the sealing action of which is independent of the pressing force onto the holding flange.

In one embodiment of the invention, it can be provided that the axially acting sealing surface is formed on the inflow side of the retaining flange. The sealing ring can be simply installed.

It can be provided here that an axially acting mating sealing surface is formed on the valve. The mating sealing surface can be provided, for example, by an incorporated sealing ring.

In one embodiment of the invention, it can be provided that the radially acting sealing surface is formed on a connecting piece which protrudes beyond the retaining flange on the inflow side. Thus, a radial seal can be produced that is simple, in particular by thermoplastic molding.

It can be provided here that a radially acting mating sealing surface is formed on the valve. In this case, the pressure of the valve can advantageously be used for forming the seal. The mating sealing surface can also be formed on the sealing ring.

In one embodiment of the invention, it can be provided that the circumferential edge of the inlet opening at the end of the connecting tube has sharp edges. This enables a slotless construction of the transition between the connection hose and the functional unit. Such grooves can cause turbulence in the flowing water and thus undesirably reduce the net effective cross-section at the transition.

For example, it can be provided that the sharp-edged edges are formed by means of a tool without radius. In particular in the case of thermoplastic shaping, simple tools can be used to achieve as smooth a transition as possible.

Alternatively or additionally, the circumferential edge can be configured to be flush with the valve. This makes it possible to avoid a constriction of the flow cross section and/or an increase in the flow resistance. Avoidance of irregularities on the transition also reduces the likelihood of dirt deposition in this region.

In one embodiment of the invention, it can be provided that the functional unit is a mixing drum. Thus covering frequent use cases.

In one embodiment of the invention, the connection hose may be a mixing water hose. The invention is used here in that the mixing water hose is generally subjected to a small operating pressure and the load of the fluid connection on the holding flange can thereby be reduced.

In a preferred application, in order to solve the task, a sanitary fitting is proposed, which comprises the water-guiding arrangement according to the invention, in particular as described above.

Here, it can be provided, for example, that the connection hose is guided as a discharge hose to a water outlet of the sanitary fitting. It is thus achieved that the operating pressure differs only slightly from the ambient pressure when the pressure drop over the water outlet opening is small. This simplifies the requirement for fatigue-resistant tightness on the retaining flange.

Alternatively or additionally, it can be provided here that at least one supply hose of the functional unit, in particular of the valve, has a hose connection. The connection with the hose connection, which is resistant to pressure, on the functional unit can thus be combined with the connection via the retaining flange, for example on the discharge side.

Detailed Description

Fig. 1 to 6 and 9 show a first embodiment and are then explained together.

The sanitary fitting, generally designated 1, has an arrangement 2 for guiding water. The water-guiding arrangement 2 has at least one sanitary functional unit 3, a connection hose 4 and further connection hoses 5.

The functional unit 3 has two inputs and an output, wherein the further connecting hose 5 is connected to the inputs and the connecting hose 4 is connected to the outputs.

A holding flange 7 is formed at the end 6 of the connecting hose 4 facing the functional unit 3.

The functional unit 3 has a functional body 8 and a support plate 9.

The further connecting hoses 5 each have a connecting piece 10, which has a hose connection 13 and a crimp sleeve 14, in a manner known per se. The connecting piece 10 is suspended in a manner known per se on the carrier plate 9 into the hose receptacle 11.

The holding flange 7 of the connecting hose 4 is hung directly into the hose receptacle 12 on the carrier plate 9 without a separate joint.

The holding flange 7 is made of the same material as the connecting hose 4 and is formed in one piece on the connecting hose 4.

The connecting hose 4 is made of a thermoplastic material which is sheared correspondingly before assembly. The holding flange 7 is formed thermoplastically on the connecting hose 4 by means of a heated die, from the hose material, so that the hose material is pushed up in order to form the holding flange 7.

In fig. 4, it can be seen that the hose receptacle 12 is formed in a circumferentially closed manner, so that the connecting hose 4 must be inserted into and extended through the hose receptacle 12 to the holding flange 7 during assembly.

In the exemplary embodiment shown, the functional unit 3 is designed as a valve 15 which can be actuated by means of an actuating element 16 which is accessible from the outside in order to control the flow from the further connecting hose 5 into the connecting hose 4.

The connection hose 4 is thus designed as a discharge hose 17, which is connected on the low-pressure side of the functional unit 3 in the manner described in the way described above with the holding flange 7.

In fig. 5 and 6, it can be seen that the underside 18 of the holding flange 7 is formed from time to time flat, but has a structure.

By this construction, a pulling anchor 19 is formed, which acts in the radial direction and prevents the holding flange 7 from being pulled through the hose receptacle 12. This risk may occur, for example, when the connecting hose 4 is heated by hot water flowing therein to such an extent that the shape stability is significantly impaired or no longer exists.

The mentioned pull anchors 19 are formed in the exemplary embodiment by ribs 20 on the underside 18, which engage in corresponding grooves 21 on the carrier plate 9 on a support surface 22 for the holding flange 7.

The groove 21 thus forms a mating pulling anchor 23, which in interaction with the pulling anchor 19 causes a radial locking and fixing of the holding flange 7.

On the upper side 24 of the holding flange 7, a sealing surface 25 is formed, which enables an axial sealing.

Since the connecting hose 4 is formed and used as the discharge hose 17 in this embodiment, the upper side 24 is the inflow side 26.

An adapted mating sealing surface 27 comprising an axially sealing ring 28 is formed on the functional body 8. In the use position, the functional body 8 is pressed against the carrier plate 9, so that the pull anchor 19 and the mating pull anchor 23 are held in the active position on the one hand and the sealing ring 28 is pressed onto the sealing surface 25 on the other hand, in order to cause a seal.

It can also be seen in the detail view according to fig. 2 that an inlet opening 29 of the connecting hose 4 is formed at the end 6, said inlet opening having a sharp edge 30 or a radius-free edge 31. This gives a smooth transition 32 to the functional body 8 without irregularities in the wall of the liquid guide leading to turbulence.

The valve 15 is a mixing drum 33, wherein the connecting hose 4 is guided as a mixing water hose 34 to a water outlet 35 on the end of a discharge pipe 36.

Fig. 7 and 8 show a variant of the combination of the connecting hose 4 and the carrier plate 9, which can be installed in the water-guiding arrangement 1 according to fig. 1 to 4 instead of the combination according to fig. 5.

The same reference numerals are given and the functional and functional elements that are functionally and/or structurally identical or equivalent to those of the previous embodiments are not specifically described again. The implementation of the previous embodiment is thus correspondingly applicable to fig. 7 and 8.

In the embodiment according to fig. 7 and 8, the pull anchors 19 and the mating pull anchors 23 are formed by ribs 20 in the bearing surface 22 and corresponding grooves 21 on the underside 18 of the holding flange 7.

In other embodiments, other combinations of grooves and ribs or other mechanisms for positive locking action are implemented.

Fig. 10 to 16 show another embodiment. Again, the same reference numerals are used to designate and not again separately describe structural and/or functional elements and functional units that are structurally identical or equivalent to those of the previous embodiments. The embodiments of fig. 1 to 9 are thus correspondingly suitable for fig. 10 to 16.

The embodiment according to fig. 10 to 16 is distinguished from the previous embodiment in that the hose receptacle 12 is open laterally, as is the case in the hose receptacle 11.

In order to hold the holding flange 7 on all sides in this case, a support disc 37 is provided in the hose receptacle 12, which constitutes the support surface 22.

The support disk 37 is made of a non-thermoplastic material, for example metal. In the illustrated embodiment, the support disc 37 is stamped or bent.

In other embodiments, the support disk 37 is made of a non-metallic material, such as plastic.

In other embodiments, sharp-edged structures, for example holding claws, can be formed on the support surface 22, with which the support disk 37 can be clamped in the holding flange 7.

Fig. 17 to 20 show another embodiment according to the invention. Again, the same functional units are denoted and functionally and/or structurally the same or equivalent components and functional units as in the previous embodiments are not separately described again. The embodiments of fig. 1 to 16 are thus correspondingly suitable for fig. 17 to 20.

The embodiment according to fig. 17 to 20 differs from the previous embodiment in that the axially acting sealing surface 25 is not formed at the inflow end 6, but rather the connecting piece 38 is formed. The connecting piece 38 forms a radially oriented sealing surface 25 which engages into a sealing ring 28 which engages into a lower part 39 of the functional body 8 and is radially compressed.

In the water-guiding arrangement 1, it is therefore proposed according to the invention to form a retaining flange 7 on one end 6 of the connecting hose 4, which engages behind the hose receptacle 12 in order to hold the connecting hose 4.
