Description

Technical Field

[0001] The invention relates to a fluid arrangement comprising a valve, a discharge piece which can be connected to a discharge pipe of a fitting, and a hose which fluidically connects the discharge piece to the valve.

[0002] The invention furthermore relates to a fitting comprising a fitting housing in which a valve is arranged, a discharge pipe in which a discharge piece is arranged and which is connected to the fitting housing, and a hose which fluidically connects the discharge piece to the valve. Background Art

[0003] Generally, a fitting may be, for example, a housing for a path for a fluid for the purpose of releasing the fluid and usually features a valve for controlling the fluid flow. In principle, two different types are known. In one type, the fitting housing is in contact with the fluid, and in the other type, the fitting housing receives a fluid arrangement which itself is in contact with the fluid and thus avoids contact of the fluid with the fitting housing.

[0004] Such fittings are known, for example, in the form of kitchen fittings with a pivotable outlet. Such fittings have the disadvantage that the fluid seal at the pivot point is very complex. Furthermore, the arrangement of the valve in the fitting body greatly restricts the shaping. Furthermore, the jet-guiding outlet element must be sealed relative to the fitting, which is technically simple to implement only with a circular jet shaping. This also leads to severe restrictions on the design of such fittings. Fittings are also known in which the fitting housing is designed as part of a piece of furniture, for example as a shelf plate or wall panel.

[0005] A sanitary fitting as an example for a fitting can be characterized, for example, in that it forms at least one outlet pipe, the orientation of which can be predetermined by mounting the sanitary fitting on or beside the base support. Summary of the invention

[0006] The object of the present invention is to improve such an accessory.

[0007] This object is achieved by a fluid arrangement, a use and a fitting according to the independent claims.

[0008] In one embodiment of a fluid arrangement of the type mentioned above, the discharge piece has a non-circular circumferential contour. Since the discharge piece is inserted into a discharge piece connection, in particular a discharge piece receptacle, which is preferably made of plastic and is fluid-tight relative thereto, according to this embodiment, the need to seal the discharge piece directly relative to the outlet opening of the fitting is eliminated. This simplifies the sealing due to the largely free shaping of the discharge piece connection, which is preferably made of plastic and is optionally detachably connected to the outlet opening of the fitting. In this way, the shaping of the discharge piece and the fitting is largely decoupled.

[0009] The discharge piece can be detachably connected to a discharge piece connection, which is formed on the discharge hose. This allows, for example, a simple replacement of the discharge piece as a jet regulator. The discharge piece connection can be formed here so as not to be lost, for example, connected in a materially sealed manner or fixed to the discharge hose in a pull-out-proof manner. For the pull-out-proof fixing, for example, a clamping jaw is provided, which is grippingly connected to the discharge hose and is held in a self-locking manner on the discharge piece connection by a restraining device. Embodiments are also known and can be used in which the restraining device can be placed in a release position in order to disengage the gripping connection and release the discharge hose.

[0010] In general, the discharge element can be designed to achieve a desired jet quality of the discharged water jet. For example, the discharge element can have a splitter stage, which can, for example, split the incoming water flow into a plurality of individual jets, and / or a mixing stage, which can, for example, allow the mixing of air into the water jet. A typical example of a discharge element is a (preferably aerated or unaerated) jet regulator, another example is a jet shaper. The discharge element can also have at least one valve function, for example as a switch or as a shut-off valve.

[0011] In this way it is possible to provide fittings with unusual shapes or to integrate the discharge piece into a piece of furniture completely without fittings, wherein alternative designs are possible due to the non-circular shape.

[0012] Therefore, in the present invention, there is no need for sealing of the discharge member relative to the discharge pipe, so that the discharge member can accept any shape. In particular, the discharge member can be elliptical or substantially angular, also with rounded corners.

[0013] The outlet part connection can be used for the fluid-tight connection of the outlet part to the outlet hose. Wetting of the sanitary fittings can thus be avoided; sanitary fittings can also be completely omitted, for example by arranging the fluid arrangement on the furniture part.

[0014] For example, the outlet piece connection can be designed as an outlet piece receptacle, into which the outlet piece can be inserted, in particular screwed and / or clipped, in a fluid-tight manner.

[0015] Generally, the discharge piece can be arranged in a discharging piece connection, such as the already mentioned discharging piece receiving portion, in a loss-proof manner. This can be done, for example, by a connecting mechanism that prevents automatic detachment or makes it difficult.

[0016] In another embodiment, the outlet tube is alternatively or additionally designed to be pivotable relative to the fitting housing.

[0017] This can be achieved by the use of the fluid arrangement according to the invention. Advantageously, the fitting housing on the pivotable outlet pipe does not need to be sealed, since fluid contact with the fitting housing can be avoided. Such seals often cause problems with regard to durability.

[0018] The outlet hose is preferably unarmored, since no tensile loads occur during use and since no longitudinal displacements occur during use, so that no wear occurs. Alternatively or additionally, the outlet hose can be extruded and / or formed in a single layer.

[0019] Particularly advantageously, fittings, in particular sanitary fittings, are formed in the manner described at the outset, wherein a fluid arrangement is installed so that the discharge hose is guided in the discharge pipe. If the discharge pipe is pivotable, the discharge hose can provide the required flexibility so as not to hinder this pivoting movement.

[0020] The outlet hose can have a fixed reversing device at a location spaced apart from its two ends, which reversing device can be optionally detached and is designed in a U-shaped or V-shaped manner in one embodiment. In addition, the fitting housing can have a channel in which a section of the outlet hose is guided and in which the section of the outlet hose can be rotated about an axis extending longitudinally with respect to the pivot axis of the outlet pipe, in particular parallel to the pivot axis. In this way, a pivoting of the outlet pipe can be achieved, wherein the hose is rotated in the channel. This rotatability is ensured by the channel, since the hose does not have to be restricted or clamped in the channel by other structural elements.

[0021] Alternatively or additionally, it can be provided that the outlet hose is fastened rotatably about its longitudinal axis in the reversing device and / or in the outlet connection. Compensation of torsional stresses can thus be achieved in a simple manner. Alternatively or additionally, it can also be provided that the mixed water hose connected to the reversing device, which is described in more detail further below, is rotatably connected to the reversing device and / or the valve. This also enables compensation of torsional stresses in the outlet hose.

[0022] The rotatability can be achieved, for example, by a respective restraining device that is rotatable relative to the clamping jaw holder and / or by a clamping jaw holder that is rotatable on a received (eg drainage or mixing water) hose.

[0023] In particular, in conjunction with the above-described embodiments, it is not necessary to seal the outlet pipe relative to the fitting housing of the fitting, so that the fitting can be produced more simply and at a lower cost and moreover requires fewer components than in the prior art.

[0024] In another embodiment, the discharge element is alternatively or additionally connected to the valve fluid. The valve is arranged below the foot of the sanitary fitting, in particular outside the fitting housing, and a control connection to the valve is provided. The fitting housing also has a channel in which a hose is guided between the valve and the discharge element and / or a control connection is guided. In this way, the valve can be arranged away from its actuation. The fitting can thus be designed very compactly and also relatively free in terms of shaping, since no space for a valve or a valve cartridge is required. The valve is triggered via the control connection.

[0025] The control connection can act here, for example, mechanically and / or fluidically (hydraulically, pneumatically).

[0026] The valve can be a conventional valve or a diaphragm valve, for example, which can be triggered by a pilot valve. The control connection can be present in a manner suitable for the pilot valve or establish an operative connection between the pilot valve and the valve.

[0027] In contrast to the above-mentioned kitchen fittings, it is provided according to the invention that the hose is connected directly to the outlet and that the outlet is connected directly to the valve. In the known kitchen fittings, the pull-out spray device is connected to the hose and thus the entire spray device conducts water. This is possible because the water is conducted from the valve to the outlet via the hose and therefore the outlet pipe itself does not need to conduct water.

[0028] The control connection is preferably formed as a rod, a flexible tube, a Bowden cable or an articulated rod. Other embodiments may also have an electrically actuated pilot valve, so that the control connection can also be formed by an electrical conductor. In addition, the control connection can also have a hydraulic or pneumatic connection between the pilot valve and the main valve.

[0029] In one embodiment, the sanitary fitting has a fastening element, with which the valve is fastened to a fitting housing and / or a fitting holder. In this way, a simple assembly of the valve can be achieved.

[0030] The accessory holder can be denoted, for example, as a lower support, on which sanitary accessories can be fixedly mounted for use. For example, the accessory holder can be configured as a washstand or as a stand bottom.

[0031] In one embodiment, the discharge element has a polygonal and / or concave circumferential contour.

[0032] The circumferential contour can also be composed of straight and curved lines. For example, a rectangular contour can be formed which comprises two semi-circular disks arranged on opposite sides, the diameter of which is the same as the length of the sides.

[0033] In one embodiment, the discharge piece is inserted into a discharge piece receptacle fixed to the fitting housing. An advantage here is that the discharge piece receptacle does not have to be sealed relative to the fitting housing.

[0034] In one embodiment, the discharge piece receptacle has an outer contour that matches the inner contour. This means that the outer contour is substantially shaped identically to the inner contour.

[0035] In one embodiment, the discharge piece is fixed by a snap-on connection. In this way, locking of the discharge piece is possible without screwing it in. In particular, the discharge piece can be fixed or assembled without tools.

[0036] In one embodiment, a sealing device is provided between the discharge piece and the discharge piece receptacle.

[0037] In one embodiment, the passage extends at least between the fixed reversing device and the water outlet and / or between the fixed reversing device and the valve. In this way, the hose can be formed on the course of the fluid from the valve to the discharge member with at least one change of direction.

[0038] Here, a fixed reversing device can be represented, for example, as a reversing device at a fixed position in the hose. When the hose is bent or the shape changes, the fixed reversing device does not move together in this sense.

[0039] In one embodiment, the channel extends separately from the inlet hose and the outlet hose of the valve. In this way, friction between the hoses can be prevented, which could damage the hoses or hinder the pivoting movement.

[0040] In one embodiment, the hose is rotatably fastened in the switching device and / or the valve. In this way, compensation of a twist on a twisted hose is possible. Thus, the stability of the fluid arrangement can be increased.

[0041] In one embodiment, the lateral inner dimension of the channel is at least twice as large as the diameter of the hose. In this way, both the upwardly directed section of the hose and its downwardly directed section, ie to and from the reversing device, can be movably received in the channel. The hose can be deflected laterally.

[0042] In one embodiment, the fitting housing is designed without a seal at at least one pivot point of the outlet pipe. This increases operational safety and stability. Since the seal is always subject to wear, the fitting inevitably becomes loose at this sealing point over time. This is avoided by the advantageous design, since no seal is required and is not provided. In this way, a greater degree of freedom is also provided with regard to the choice of shape and material.

[0043] In one embodiment, the mixing water hose is fluidically connected to the valve at a position facing away from the outlet piece in the use position of the valve. A lateral outlet on the valve can thus be avoided. This can be advantageous for the design of the fitting, since less lateral installation space is required.

[0044] In one embodiment, the outlet hose extends outside the fitting housing in a section between the outlet piece and its valve-side end, in particular wherein the reversing device is arranged outside the fitting housing. In this way, a simple assembly of the hose and the reversing device can be achieved.

[0045] In one embodiment, the outlet hose is fluidically connected to the mixed water hose via a connecting element which forms the reversing device.

[0046] In one embodiment, the reversing device produces a change of direction, in particular a reversal of direction, of the flow between the mixing water hose and the outlet hose.

[0047] The invention furthermore comprises a fluid arrangement comprising a valve, a hose, an outlet piece and an outlet piece receptacle for forming a sanitary fitting according to one of the preceding claims. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] Figure 6 A cross-sectional view of a reversing device showing a fluid arrangement. DETAILED DESCRIPTION

[0056] Figure 1 As an example for a fitting according to the invention, a sanitary fitting 1 is shown, which comprises a fitting housing 2. In this example, the fitting housing 2 has a lower housing part 3, which is designed, for example, for fastening to a washstand or a kitchen worktop, and an upper housing part 4. A valve 5, for example in the form of a closed valve cartridge, is arranged in the upper housing part.

[0057] The valve 5 has two inlet connections 6, into which in the example described, a cold water hose 7 and a hot water hose 8 are connected. The hoses 7, 8 can be connected to the valve 5, for example, by means of a plug connection, in which the hoses are inserted directly into a plug connection receptacle. In particular, no hose connections or similar connecting elements are required in this case.

[0058] The valve 5 also has an outlet connection 9 which is designed similarly to the inlet connection 6 as a direct plug-in connection receptacle into which a mixed water hose 10 can be inserted.

[0059] The plug connection is preferably designed to be rotationally fixed on the outlet connection 9 , so that the mixed water hose 10 cannot be rotated about its axis in the plug connection receptacle.

[0060] Independently of this, the plug connection of the input connector 6 can also be designed to be rotationally fixed.

[0061] The sanitary fitting 1 further comprises an outlet pipe 11 which in this embodiment is arranged pivotably on the fitting housing 2 between the lower housing part 3 and the upper housing part 4, wherein the pivot axis extends approximately vertically through the center of the fitting housing 2. The outlet pipe 11 extends approximately radially relative to the fitting housing 2, wherein the outlet pipe is inclined upward relative to the horizontal.

[0062] The outlet piece 13 is arranged at the free end 12 of the outlet tube 11 .

[0063] The discharge element 13 can have a decomposer stage and a mixing stage in a manner known per se, optionally a quantity limiting stage and / or a quantity reducing stage. For example, the discharge element 13 can be a jet regulator.

[0064] According to one embodiment of the invention, the discharge piece 13 has a non-circular circumferential contour. A discharge piece connection 23 , here a discharge piece receptacle 14 , is provided in the discharge pipe 11 , to which the discharge piece 13 is connected or inserted.

[0065] The inner contour of the discharge piece receptacle 14 is preferably adapted to the outer contour of the discharge piece 13 , ie is designed in such a way that the discharge piece 13 can be inserted into the discharge piece receptacle 14 with a seamless fit.

[0066] Independently of this, the outer contour of the discharge piece receptacle 14 can be adapted to its inner contour.

[0067] A discharge hose 15 is arranged in the discharge pipe 11, which is fluidically connected to the discharge piece 13. Preferably, a non-rotatable plug connection is also used here. The discharge hose 15 can be directly, that is, directly fixed to the discharge piece 13. Alternatively, the discharge hose can also be connected to the discharge piece receptacle 14, as shown in the example.

[0068] As long as the discharge piece 13 is fluidically connected via the discharge hose 15, sealing of the discharge piece 13 relative to the discharge piece receptacle 14 and / or the discharge pipe 11 is not necessary. If the discharge hose 15 is connected to a discharge piece connection 23, for example the discharge piece receptacle 14, it is advantageous to provide a sealing device between the discharge piece 13 and the discharge piece connection 23, in particular the discharge piece receptacle 14.

[0069] The discharge piece 13 can be removably fixed in the discharge piece receptacle 14 , preferably without tools, by means of a latching or snap connection.

[0070] The outlet hose 15 and the mixed water hose 13 are fluidically connected to one another via a reversing device 16. The reversing device 16 is designed in an approximately U-shaped manner and has two plug-in connection receptacles, into which the outlet hose 15 and the mixed water hose 13 can each be inserted. It is advantageous that the plug-in connections are also designed to be non-rotatable here.

[0071] It is particularly advantageous here if the mixing water hose 13 is dimensioned so long that the switching device 16 is located outside the fitting housing 2. In this way, the switching device 16 can be easily installed at a desired location after the sanitary fitting 1 is installed. For this purpose, the valve-side end 35 of the outlet hose 15 extends into a region outside the fitting housing 2.

[0072] The valve 5 , the outlet hose 15 , the mixed water hose 13 , the switching device 16 , the outlet piece 13 and the outlet piece connection 23 form a fluid arrangement 32 . The fluid arrangement 32 can be operated without the fitting housing 2 and without the outlet pipe 11 .

[0073] According to one embodiment of the invention, the fitting housing 2 has a channel 17, in which at least the mixed water hose 13 and preferably also the outlet hose 15 are guided. The cross section of the channel 17 is preferably dimensioned in such a way that it is twice as large as the cross section of the hose guided therein. The two hoses 13 and 15 are now freely guided in the channel and in particular have no bends or contacts, for example, with the cold water hose 7 and / or the hot water hose 8. This allows the outlet pipe 11 to be freely pivotable. This is because when the outlet pipe 11 is pivoted, the outlet hose 15 is also forced to rotate in the channel. This rotation is transmitted to the mixed water hose 13 via the reversing device 16.

[0074] In particular, a rotationally fixed plug connection or, in general, a rotationally fixed connection of the hoses 13 and 15 to the switching device 16 and the valve 5 plays a role here. This is because a rotationally fixed connection can be designed to be permanently sealed more easily than a rotatable connection. By pivoting the outlet pipe 11, the torsional forces occurring in the hose can be easily absorbed by the rotationally fixed connection, so that only the mixed water hose 10 and / or the outlet hose 15 are twisted.

[0075] It may be advantageous here if the mixed water hose 13 and / or the outlet hose 15 are accommodated with play in the channel 17. In this way, for example, assembly can be simplified.

[0076] The channel 17 can also be designed to be structurally separate within the fitting housing 2 .

[0077] Another advantage of this arrangement is that the outlet pipe 11 has no seal relative to the fitting housing 2 at its pivot point 18. This is because the outlet pipe 2 does not conduct water overall. As a result, the pivot points 18 can be designed to be simpler and more durable. And no wear of the seals at these pivot points 18 occurs.

[0078] Figure 2 Another embodiment of a sanitary fitting 1 is shown, which has a slightly different Figure 1 However, the same or functionally identical features are provided with the same reference numerals. Figure 1 Different characteristics.

[0079] The fitting housing 2 in this example has an outlet pipe 11 which is arranged vertically upward on the upper housing part 4 approximately in the extension of the center axis of the fitting housing 2. The outlet pipe 11 is designed to be approximately U-shaped here. Thus, in this embodiment, there is only a pivot point 18 between the fitting housing 2 and the outlet pipe 11.

[0080] In this embodiment, the valve 5 is arranged laterally on the fitting housing 2 , wherein a valve cartridge is also used here.

[0081] The drain hose 15 is guided here through the valve 5 in a channel 17. In particular, the channel 17 is dimensioned at this location so that the drain hose 15 is neither clamped nor impeded in its movement in another way. This prevents the drain hose 15 or the sanitary fitting 1 as a whole from being damaged by pivoting the drain pipe 11.

[0082] Figure 3 Another embodiment of a sanitary fitting 1 is shown, which has a Figure 1 The sanitary fittings 1 of the embodiment of the present invention are of a slightly different construction. However, identical or functionally identical features are provided with the same reference numerals. Figure 1 Different characteristics.

[0083] The outlet pipe 11 of the sanitary fitting 1 is in this embodiment Figure 1 However, the valve 5 is not arranged in the upper housing part 4 here, but is arranged completely outside the fitting housing 2. For example, under the washstand 19, in any case under the foot of the sanitary fitting 1.

[0084] An actuating element 20 for the valve 5 is arranged on the upper housing part 4 of the sanitary fitting 1, which is connected to the valve via a control connection 21. The control connection 21 can be designed, for example, as a rod, a flexible tube, a Bowden cable or an articulated lever. The control connection 21 is guided in the channel 17 in the embodiment shown. In this embodiment, it is advantageous that the sanitary fitting 1 has practically no restrictions in its shape, since all water-conducting elements are connected via hoses and are in principle located outside the sanitary fitting 1. In this embodiment, the assembly of the hose is also simplified, since the hose is freely accessible.

[0085] Figure 4 Another exemplary embodiment is shown. Functionally and / or structurally similar or identical components and functional units to the previous exemplary embodiment are denoted by the same reference numerals and are not described separately again. The embodiments of the previous exemplary embodiment therefore apply accordingly. Figure 4 .

[0086] according to Figure 4 Embodiments and methods of Figure 3 The exemplary embodiment of is distinguished at least in that the control connection 21 is fluidic and produces an operative connection between a pilot valve 30 , which can be actuated mechanically, for example, and the valve 5 (as a main valve).

[0087] For this purpose, the control connection 21 has a discharge line 33 to the pilot valve 30 and a return line 34 from the pilot valve to the valve 5 .

[0088] Figure 5 A more detailed view of a valve 5 is shown. Functionally and / or structurally similar or identical components and functional units to those of the previous exemplary embodiment are denoted by the same reference numerals and are not described separately again. The embodiments of the previous exemplary embodiment therefore apply correspondingly to Figure 5 .

[0089] The inlet connection 6 and the outlet connection 9 are arranged in a two-part pressure housing 24, which is exemplarily arranged here. The pressure housing 24 surrounds the valve 5 and establishes a fluid connection. The pressure housing 24 can in particular receive the operating pressure of the inlet connection 6, so that the valve 5 can be arranged outside the sanitary fitting 1.

[0090] Figure 6 1 shows a more detailed view of the reversing device 16. Functionally and / or structurally similar or identical components and functional units to those of the previous exemplary embodiment are denoted by the same reference numerals and are not described separately again. The embodiments of the previous exemplary embodiment therefore apply correspondingly to Figure 6 .

[0091] The reversing device 16 has two clamping jaws 26 with clamping jaws 27, with which one hose, here by way of example the mixed water hose 10 and the outlet hose 15, can be held in a tension-resistant manner. The clamping jaws 26 are arranged here in a rotatable but self-locking manner in a restraining device 28. Twists in the hose can be easily compensated by a relative rotation of the clamping jaws 26 with respect to the restraining device 28.
