Description

Arrangement for guiding water

Technical Field

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

Background

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

Disclosure of Invention

The object of the invention is to provide a simple, fluid connection that can be established in a water-conducting arrangement.

To solve this object, the invention is characterized by the features of claim 1. In particular, in a water-conducting arrangement of the type mentioned at the outset, it is proposed according to the invention that an integrally formed retaining collar is formed in one piece on the end of the connecting hose facing the functional unit and is hooked on the hose receptacle of the valve. The hose connection on the connecting hose can therefore be dispensed with. This simplifies the establishment of the fluidic connection. When the hose connector is no longer required, the net internal cross section can be selected to be large at constant external dimensions. This is advantageous for as low a flow resistance as possible.

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

For example, the connecting hose may be an inlet hose. The invention can therefore 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 may positively affect the long-term stability of the fluid connection.

For example, the connecting hose may also be a discharge hose. The invention makes use of the fact 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 across the functional unit.

In one embodiment of the invention, it can be provided that the connecting tube is made of a thermoplastic material. The holding flange can thus be shaped particularly simply.

In one embodiment of the invention, it can be provided that the retaining flange is formed by thermoplastic molding. The connecting hose can advantageously be produced from an extruded material. The retaining flange can in this case be shaped, for example, after the connecting hose has been cut off.

In one embodiment of the invention, it can be provided that the hose receiving section is laterally open. So that the connection hose does not have to be threaded in.

In one embodiment of the invention, it can be provided that the hose holder is closed around. Thus, the retaining flange can be supported along the entire circumference.

In one embodiment of the invention, provision may be made for radially acting pulling anchors to be formed on the retaining flange. Thus, a pull-out prevention device can be provided. This is particularly advantageous in the case of connection hoses which, by heating with flowing warm water, lose their shape stability partially or lose.

It can be provided here, for example, that the pulling anchor is designed as a groove or a rib. A positive connection between the retaining flange and the hose receptacle can thus be established with a simple mechanism. The hose receiving portion can be provided with a corresponding shape, for example, in particular on the bearing surface.

The groove or rib can 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 retaining flange is pressed against a bearing surface on the hose receiving section. The retaining flange is thus prevented from slipping out. It is particularly advantageous here if the pulling anchor already described is formed on the holding flange. By means of the pressing force, it is possible to achieve that the form-locking of the pulling anchor also does not undesirably disengage at hot water temperatures.

In one embodiment of the invention, it can be provided that a bearing surface, such as the one already mentioned, on the hose receptacle is formed in correspondence with the retaining flange. A form closure can thus be established.

It can be provided here, for example, that a radially acting co-operating pulling anchor is formed in this way. By 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 retaining flange.

A simple design of the form-locking is provided by at least one, preferably circumferential rib, which engages in the groove. Additional sealing can thereby be achieved.

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

In one embodiment of the invention, it can be provided that the hose receiver has a circumferential support plate, against which the retaining flange rests. In this case, it is advantageous if, independently of the design of the functional unit, a support of the retaining collar on all sides is possible, in particular when the hose receiving section is open laterally.

The support plate is preferably designed to be removable. This may simplify disassembly. Different materials can 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 designed as a stamping and/or bending part. The support plate can thus be made of metal, for example, while the already mentioned carrier plate of the functional unit can be made of plastic.

For example, it can be provided that the support disk is formed as a die cast part, in particular as a zinc die cast part. Alternative materials may be used.

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

Alternatively or additionally, provision may be made for the support surface for the retaining flange, which support surface is in particular already described, to be formed with sharp edges. These sharp-edged structures can be embedded in the retaining flange in order to positively retain the structures. This can be achieved particularly simply when the support disk is a stamping and/or bending and/or die-casting, for example of metal, in particular a zinc die-casting.

The sharp-edged structure can have at least one holding claw, for example. This means that a particularly simple production is possible.

In one embodiment of the invention, it can be provided that a sealing surface is formed on the end of the connecting tube. It is advantageous here that the sealing function can be integrated into the retaining flange. Other sealing mechanisms may be dispensed with. The connecting hose can therefore 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, for example, circumferentially. Sealing on all sides can thus be achieved.

It may be provided that the sealing surfaces act axially. The contact pressure on the retaining flange, in particular the contact pressure described above, can thus be used for sealing.

Alternatively or additionally, it can be provided that the sealing surfaces act radially. An arrangement is therefore described, the sealing action of which is independent of the contact pressure on the retaining 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 thus be mounted simply.

Here, provision can be made for axially acting mating sealing surfaces to be formed on the valve. The mating sealing surface can be provided, for example, by a built-in 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 projects beyond the retaining flange on the inflow side. A radial seal can thus be formed which is simple, in particular can be produced by thermoplastic forming.

Here, provision can be made for radially acting mating sealing surfaces to be formed on the valve. It is advantageous here to use the contact pressure of the valve 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 a sharp-edged edge. This enables a groove-free configuration 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 edges of the sharp edges are formed by means of a tool without a radius. Simple tools can therefore be used, in particular in the shaping of thermoplastics, for obtaining a transition which is as smooth as possible.

Alternatively or additionally, provision may be made for the circumferential edge to be formed flush with the valve. This can often avoid a constriction in the cross-section of the flow and/or an increase in the flow resistance. The avoidance of irregularities on the transition also reduces the possibility 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, it can be provided that the connection hose is a mixing water hose. The invention makes use of the fact that the mixing water hose is usually subjected to low operating pressures and the load of the fluid connection on the retaining flange can thereby be reduced.

In order to solve the problem, a preferred application provides a sanitary fitting which comprises a water-guiding arrangement according to the invention, in particular as described above and/or in accordance with the claims for a water-guiding arrangement.

In this case, it can be provided, for example, that the connecting 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 is small. This simplifies the requirement for fatigue-resistant sealing 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. A pressure-resistant connection on the functional unit by means of the hose connector can thus be combined with said connection via the retaining flange, for example on the outlet side.

Detailed Description

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

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

The functional unit 3 has two inputs and one output, wherein the further connecting hoses 5 are connected to the inputs and the connecting hoses 4 are connected to the outputs.

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

The function unit 3 has a function body 8 and a bracket plate 9.

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

The retaining flange 7 of the connecting hose 4 hangs directly without a separate connection into the hose receiving portion 12 on the carrier plate 9.

The retaining flange 7 is made of the same material as the connecting tube 4 and is integrally formed on the connecting tube 4.

The connecting hose 4 is made of a thermoplastic material which is cut off accordingly before assembly. The retaining flange 7 is formed thermoplastically from the hose material on the connecting hose 4 by means of a heated die punch, so that said hose material is pushed up to form the retaining flange 7.

Fig. 4 shows that the hose receptacle 12 is closed around, so that the connecting hose 4 must be inserted through the hose receptacle 12 and extended as far as the retaining 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 other connecting hose 5 into the connecting hose 4.

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

As can be seen in fig. 5 and 6, the underside 18 of the retaining flange 7 is formed flat from time to time, but has a structure.

By means of 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 can occur, for example, if the connecting hose 4 is heated by the hot water flowing therein to such an extent that the dimensional stability is significantly reduced or no longer exists.

The mentioned pulling anchor 19 is formed in the exemplary embodiment by a rib 20 on the underside 18, which engages in a corresponding groove 21 on the carrier plate 9 on a bearing surface 22 for the retaining flange 7.

The slots 21 thus form cooperating pull anchors 23 which, in interaction with the pull anchors 19, cause radial locking and fixing of the holding flanges 7.

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

Since the connection hose 4 is constructed and used as a discharge hose 17 in this exemplary embodiment, the upper side 24 is the inflow side 26.

A suitable mating sealing surface 27, which comprises 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 on the one hand the pull anchor 19 and the mating pull anchor 23 remain in the active position and on the other hand the sealing ring 28 presses against the sealing surface 25 in order to cause a seal.

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

The valve 15 is a mixing cartridge 33, wherein the connecting hose 4 leads as a mixed water hose 34 to a water discharge 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, as it can be installed in the water-guiding arrangement 1 according to fig. 1 to 4 instead of the combination according to fig. 5.

Components and functional units which are functionally and/or structurally identical or equivalent to the previous embodiments are denoted by the same reference numerals and are not described again in particular. The embodiments for the previous examples thus apply correspondingly to fig. 7 and 8.

In the exemplary embodiment according to fig. 7 and 8, the pull anchor 19 and the mating pull anchor 23 are formed by a rib 20 in the bearing surface 22 and a corresponding groove 21 on the underside 18 of the holding flange 7.

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

Fig. 10 to 16 show another embodiment. Structural and/or functional components and functional units that are structurally and/or functionally identical to or equivalent to the previous exemplary embodiments are also denoted by the same reference numerals and are not described again separately. The embodiments of fig. 1 to 9 are therefore correspondingly suitable for fig. 10 to 16.

The exemplary embodiments according to fig. 10 to 16 differ from the previous exemplary embodiments in that the hose receptacle 12 is open laterally, as is already the case in the hose receptacle 11.

For the purpose of holding the holding collar 7 on all sides, a bearing disk 37 is provided in the hose receptacle 12, which bearing disk forms the bearing surface 22.

The support disc 37 is made here 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 retaining claws, can be formed on the bearing surface 22, with which the bearing disk 37 can be locked in the retaining collar 7.

Fig. 17 to 20 show a further exemplary embodiment according to the invention. The same or equivalent components and functional units as in the previous exemplary embodiments are again denoted by the same functional units and are not explained again separately. The embodiments of fig. 1 to 16 are therefore correspondingly applicable to fig. 17 to 20.

The exemplary embodiments according to fig. 17 to 20 differ from the previous exemplary embodiments in that no axially acting sealing surface 25 is formed on the inflow end 6, but rather a connecting piece 38. The connecting piece 38 forms a radially oriented sealing surface 25 which engages in a sealing ring 28 which engages in a lower part 39 of the functional body 8 and is pressed radially.

In the arrangement 1 for guiding water, it is therefore proposed according to the invention that a retaining collar 7 is integrally formed on one end 6 of the connecting hose 4, said retaining collar engaging behind the hose receptacle 12 in order to catch the connecting hose 4.
