Description

background

[0001] The present invention relates to a water outlet arrangement and in particular to a water outlet arrangement with a quick-coupling device and an outlet body, a quick-coupling device, a hose with a quick-coupling device, and a sanitary installation with a quick-coupling device.

[0002] Water outlet arrangements with couplings are known from DE 10 2006 060 929 B4, DE 196 28 780 B4, DE 198 06 634 A1, US 6,006,784, DE 100 22 350 A1 and DE 43 14 101 A1. However, these are only suitable for practical use to a limited extent. Inventive solution

[0003] According to one embodiment, a water outlet assembly comprises a quick-release coupling device with a first coupling part and a second coupling part, which can be detachably connected to each other by means of a spring-loaded coupling. For coupling, the two coupling parts are movable relative to each other along a coupling axis until the spring-loaded coupling engages. In the coupled state, the two coupling parts are freely rotatable relative to each other when the coupling is engaged. The first coupling part has a flow channel with a valve that is open when the two coupling parts are coupled and closed when they are uncoupled. The water outlet assembly further comprises a discharge body, with or without sensors and / or with or without an operating unit, which is connected to the second coupling part.

[0004] The quick-release coupling allows for easy, tool-free assembly and disassembly of the water outlet assembly. This can even be done under water pressure, as the first coupling part has a valve that blocks the flow channel on the inlet side as soon as the two coupling parts are separated.

[0005] In contrast to previous solutions, the embodiments described here employ a spring-loaded coupling to ensure a secure connection between the first and second coupling parts. To engage the coupling, the two coupling parts are moved relative to each other along the coupling axis, which typically runs in the axial direction of the coupling parts, until the spring-loaded coupling engages. When coupled, the two coupling parts can be freely rotated relative to each other. However, it is also possible to provide stops that limit this free rotation.

[0006] The free rotation allows the spout to be turned in the desired direction as needed, for example, relative to a sink. This is not possible with previously used bayonet fittings or other twist locks, as a rotational movement with these immediately carries the risk of uncoupling or loosening.

[0007] To disconnect, the outlet body and second coupling part can be pulled off along the coupling axis, automatically closing the valve in the first coupling part. Disconnection, like coupling, can be done without tools. This allows for easier cleaning and / or disinfection of sanitary facilities and the water outlet assembly.

[0008] The outlet body is preferably detachably connected to the second coupling part and can therefore be replaced. Likewise, the second coupling part can of course be replaced. This two-part design also simplifies cleaning and maintenance.

[0009] The quick-release coupling is preferably designed as a plug-in coupling. Coupling and uncoupling are achieved solely through movements along the coupling axis. Rotational movements are not required for coupling and uncoupling.

[0010] This type of mechanical coupling has the advantage that twisting the second coupling part relative to the first does not lead to accidental release of the quick-release coupling, as can happen, for example, with bayonet fittings. It is significantly more likely that the outlet body will be accidentally twisted or receive a blow in the direction of rotation during use than that it will be accidentally pulled off against increased resistance.

[0011] According to one embodiment, the spring-loaded coupling has at least one detent element pre-tensioned by means of a spring element, which is mounted in the first or second coupling part and, in the coupled state, engages in a circumferential receptacle (detent element receptacle) of the other of the two coupling parts in order to block a relative movement of the two coupling parts to each other in the direction of the coupling axis without restricting free rotation.

[0012] The locking element, for example in the form of a ball or a pin, can engage in a radially circumferential groove or recess, thereby preventing axial relative movement of the two coupling parts along the coupling axis. The strength of the coupling resistance can be adjusted, for example, by the spring force and shape of the locking element and its receptacle.

[0013] The coupling can, for example, be designed as a "click" coupling, which allows relative movement of the two coupling parts along the coupling axis until the locking element engages in the receptacle and "clicks." The locking movement of the locking element can be essentially perpendicular to the coupling axis or at an angle other than 90° to it. This makes it possible, for example, to require less force for coupling than for uncoupling, thus improving the safety of the quick-release coupling arrangement.

[0014] According to one embodiment, two or more locking elements can be provided, which engage in a common locking element receptacle, for example, in the form of a circumferential groove. It is also possible that two or more locking elements are provided, each engaging in its own locking element receptacle, for example, in spaced-apart circumferential grooves. A combination of these variants is also possible.

[0015] According to one embodiment, the valve of the first coupling part has an axially movable valve body which, in the uncoupled state of the two coupling parts, presses against a valve seat arranged in the first coupling part under spring pressure and, in the coupled state of the two coupling parts, is pushed out of its valve seat by the second coupling part.

[0016] The valve closes the flow channel running through the first coupling part, which can also be referred to as the inlet-side flow channel. Typically, during the coupling process, the valve body is pushed out of its valve seat in the direction of the coupling axis, thus opening the flow channel. A spring element can counteract this movement. Upon disengagement, the spring element then ensures the immediate closure of the inlet-side flow channel.

[0017] According to one embodiment, the second coupling part has a flow channel with a valve that is open when the two coupling parts are coupled and closed when they are uncoupled. This ensures a secure closure on the outlet side as well, preventing any backflow of water from the column of water that may be present in the outlet body, which is advantageous during cleaning and maintenance. The outlet-side flow channel can thus also be blocked.

[0018] According to one embodiment, the valve of the second coupling part has an axially movable valve body which, in the uncoupled state of the two coupling parts, is spring-loaded and presses against a valve seat located in the second coupling part. In the coupled state of the two coupling parts, the first coupling part forces the valve body out of its valve seat. The valve in the second coupling part can be constructed similarly to the valve in the first coupling part. Typically, however, the valve body in the second coupling part is moved in the opposite direction to the valve body in the first coupling part to open. During coupling, the two valve bodies can act against each other and push each other out of their respective valve seats.

[0019] The two valves may also have different designs. In particular, the valve in the first coupling part is designed to reliably block the applied water pressure.

[0020] According to one embodiment, the discharge body has at least one control unit which is connected to a transmission arrangement for transmitting signals between the two coupling parts or between the first coupling part and the discharge body.

[0021] The water outlet assembly can be operated, for example, by buttons or touch-sensitive control surfaces. These can be integrated into the outlet body. The transmission assembly transfers the signals generated by the control unit from the second coupling part to the first coupling part, from where they can be forwarded to a control device, for example, via a signal line or wirelessly. The transmission assembly can also supply power to the control unit.

[0022] The transmission arrangement can be designed as an electrical transmission arrangement, an inductive transmission arrangement, an electromagnetic transmission arrangement, and / or an optical transmission arrangement. The signals to be transmitted are then, accordingly, electrical, magnetic, electromagnetic, and / or optical signals. The couplings used can be galvanic, inductive, resistive, optical, or electromagnetic in nature.

[0023] According to one embodiment, at least one sensor (transducer) can be arranged in the first coupling part and / or in the second coupling part and / or in the outlet body. The sensor can be a temperature and / or pressure and / or pH and / or flow sensor. It can also be connected to the transmission arrangement to enable the transmission of sensor signals to the control unit. For example, this allows the water temperature to be measured very close to the outlet of the outlet body and used by the control unit for more precise control of the water temperature.

[0024] The at least one sensor can alternatively or additionally be connected to a wireless communication device located in or on the outlet body, or in the first or second coupling part. This enables, for example, remote monitoring of the sensor or integration into a central control system. Remote monitoring can be contactless, for example via WLAN, Bluetooth, NFC, or transponder technology, or contact-based.

[0025] Preferably, the sensor technology, in particular for recording the water temperature, flow rate, pH value, other parameters (skin condition, body temperature, etc.) of the user himself as well as the current switching state ("ON / OFF"), is integrated into the outlet body.

[0026] According to one embodiment, the sensor is a proximity sensor that activates the control unit and / or its illumination and / or the water supply depending on whether an object is nearby. A proximity sensor can also be part of the control unit or constitute the control unit itself. For example, the control unit can consist solely of a proximity sensor if, for instance, only cold water dispensing or dispensing water at a predetermined temperature is desired. In each case, the water temperature set during the last operation or a water temperature programmed into a mixing unit can be activated. The water temperature can also be set independently in a mixing unit that is coupled to the proximity sensor and connected to the first coupling part.

[0027] According to one embodiment, in addition to the control unit, a proximity sensor is provided, for example, on the outlet body.

[0028] According to one embodiment, a display device is arranged on or in the outlet body and is connected to the transmission arrangement. This allows information, for example about the water temperature and / or the flow rate and / or the pH value, to be output to the user.

[0029] According to one embodiment, the transmission arrangement has at least one contact element that is arranged on the first coupling part and, in the coupled state of the quick-coupling device, engages in an annular groove with an internal contact formed in the second coupling part or outlet body.

[0030] The annular groove is typically located on the side facing the first coupling part. The contact element on the first coupling part engages in the annular groove, thereby creating an electrical contact. One or more contacts, for example in the form of contact rings, can be arranged in the annular groove. The contact element may have spring-loaded contacts to ensure a reliable electrical contact. The annular groove and the contact element engaging within it ensure that the electrical contacts are protected. Furthermore, the electrical contact is maintained even if the two coupling parts are rotated relative to each other. Alternatively, the annular groove can be located on the first coupling part and the contact element on the second coupling part.

[0031] According to one embodiment, the transmission arrangement transmits signals contactlessly between the first and second coupling parts or between the first coupling part and the discharge body. This can be achieved, for example, inductively. For this purpose, a coil, for instance concentrically around the first coupling part, can be positioned in a corresponding annular recess in the second coupling part or discharge body when the two coupling parts are coupled. A coil is then arranged coaxially to this coil in the second coupling part or discharge body. However, it is also possible to achieve inductive coupling without forming an annular recess, for example, if both coils are arranged very close to the respective surface of their respective coupling parts.It is also possible that, by using a recess, one coil is radially surrounded by the other coil in the coupled state of the quick-coupling device, whereby either the coil lying in the recess can form the outer or the inner coil.

[0032] Alternatively, contactless signal transmission can be achieved using radio technology, such as WLAN, Bluetooth, NFC or transponder technology.

[0033] Furthermore, it is possible to design the transmission device as an optical transmission device for transmitting optical signals. This can be achieved, for example, by means of an optical transmitter (LED, laser, OLED) and a corresponding receiver, which is, for instance, embedded in or optically coupled to an acrylic or glass ring. The acrylic or glass ring directs the optical signals to the receiver regardless of the current rotational position.

[0034] According to one embodiment, the water outlet assembly further comprises a communication device for remote monitoring of the water outlet assembly. This device can, as described above, communicate with corresponding sensors in the water outlet assembly and / or the control unit. The communication device can enable contactless and / or contact-based communication.

[0035] According to one embodiment, the first coupling part has a coupling pin, an inlet-side connection, and a flange between the coupling pin and the inlet-side connection. The second coupling part has a coupling pin receptacle into which the coupling pin can be axially inserted.

[0036] The first coupling component can be attached to or integrated into a sanitary fixture, such as a sink, washbasin, or console. The coupling pin then protrudes from the sanitary fixture. This avoids the need for a recess or cavity with dead volume. This is particularly advantageous from a hygienic point of view, as no water remains in such "dead volumes" where bacteria or Legionella can develop. Instead, the sanitary fixture can be flush with the flange.

[0037] According to one embodiment, the outlet body can consist at least partially or entirely of a mineral material, ceramic material, glass composite, metal, plastic, or a composite of at least two of these materials. The outlet body can typically accommodate an interchangeable and modifiable aerator or mixing nozzle at the outlet. The aerators sold under the trade name PERLATOR serve as an example.

[0038] The design of the spout body can be independent of the material chosen for the quick-release coupling. For example, it is possible to mold the spout body from a mineral composite material, thus achieving virtually any external shape. The design, color, and feel of the spout body can therefore be adapted to the sanitary fixture or deliberately contrast with it.

[0039] Preferably, the outlet body completely accommodates the second coupling part, so that it is no longer visible when coupled. This is advantageous not only from an aesthetic point of view but also for ease of cleaning and handling.

[0040] According to one embodiment, a sanitary installation comprises a sanitary basin, a water outlet arrangement, and a mixing device. The mixing device has at least one first inlet, one second inlet, and at least one mixed water outlet, wherein the first coupling part of the quick-coupling device of the water outlet arrangement is connected to the mixed water outlet of the mixing device.

[0041] The sanitary fixture can be, for example, a hand basin, a bathtub, a bidet, or a shower. The sanitary basin is then formed by the actual basin body, the bathtub body, the shower tray or shower base, or the permanently installed floor with a drain. The first coupling part can be permanently mounted to the sanitary fixture, for example, in the sanitary basin, in a wall, or on a console. The drain body can be detached from the first coupling part using the quick-release coupling.

[0042] The mixing unit can include a control unit, as described above. For example, the actual supply of the service water, i.e., setting the desired pressure, flow rate, pH value, and temperature, can be performed by the mixing unit. This eliminates the need for actuating valves in the area of ​​the outlet body, allowing for a compact design of the outlet body. The quick-release coupling device housed in the outlet body can also be very compact. Furthermore, this design makes it possible to reduce the incoming water pressure, as an outlet pressure of 1 bar is perfectly sufficient in many cases.

[0043] In contrast, the line pressure in domestic water systems is typically between 3 and 6 bar. The mixing valve can therefore reduce the line pressure to the required service water pressure and, if necessary, keep it constant. However, pressure reduction by the mixing valve is not necessary, as the quick-coupling device typically tolerates or is designed for significantly higher pressures.

[0044] According to one embodiment, the mixing device can include or be connected to a desalination unit. This allows, for example, the water supplied by the mixing device to be adjusted to a desired level of hardness. The level of hardness can also be changed during operation by appropriately mixing desalinated and non-desalinated water. Furthermore, the mixing device can be used to control the targeted addition of salts.

[0045] According to one embodiment, the mixing device further comprises a control connection which is connected to the contact element of the first coupling part, for example via a signal line. This allows the mixing device to be operated and controlled directly from the discharge body.

[0046] According to one embodiment, a sanitary fitting has a hose which is connected on one side to the first coupling part of the water outlet arrangement of the quick-coupling device, and on the other side a hand shower which forms the outlet body connected to the second coupling part.

[0047] The sanitary fitting can therefore also include a flexible component. The quick-release coupling between the hose and the spout allows for easy removal of the hand shower. If the spout has controls, the user can, for example, directly control the water temperature and flow pressure with the hand holding the hand shower. Separate controls, such as faucets or the like, are not required.

[0048] According to one embodiment, the hose has at least one signal line which is connected to the contact element of the first coupling part.

[0049] The signal line can lead to a mixing device, which is used, for example, to adjust the water pressure and temperature.

[0050] The signal line can be a cable or an optical fiber. Both can be easily integrated into conduits. In the case of an optical fiber, it can simply be cast or braided into the sheathing. For cables, a metal or conductive plastic braid, which is used for pressure stabilization of conduits, can be used, for example. By using several insulated metal or plastic braids, a multi-core cable can be created.

[0051] According to one embodiment, the sanitary installation also includes a communication device for contactless and / or contact-based remote monitoring of the mixing device. This is possible with all sanitary installations described here.

[0052] According to one embodiment, a sanitary installation comprises a sanitary basin and a water outlet assembly. The outlet assembly has an inlet, wherein the first coupling part of the quick-connect device is connected to a cold, hot, or mixed water supply line.

[0053] According to one embodiment, a quick-release coupling device comprises a first coupling part and a second coupling part, which can be detachably connected to each other by means of a spring-loaded coupling. For coupling, the two coupling parts are movable relative to each other along a coupling axis until the spring-loaded coupling engages. In the coupled state, the two coupling parts are freely rotatable relative to each other when the coupling is engaged. The first coupling part has a flow channel with a valve that is open when the two coupling parts are coupled and closed when they are uncoupled. The quick-release coupling device further comprises a transmission arrangement for transmitting signals between the two coupling parts.

[0054] This description also includes a quick-release coupling device with a transmission arrangement, in particular an electrical transmission arrangement. Such quick-release coupling devices can be supplied as a kit, with, for example, standardized connections to connect any discharge body to, for example, the second coupling part, or to insert the second coupling part into the discharge body. Depending on the perspective, either the discharge body or the quick-release coupling device is therefore interchangeable. The discharge body can be supplied separately as an optional component or manufactured individually. For example, it is possible to manufacture the discharge body individually using a generative or additive manufacturing process, e.g., using a 3D printer.

[0055] The fastening between the second coupling part and the outlet body can be designed to prevent rotation.

[0056] According to one embodiment, the transmission arrangement has at least one contact element that is arranged on the first coupling part and, in the coupled state of the quick-coupling device, engages in an annular groove with an internal contact formed in the second coupling part.

[0057] According to one embodiment, the transmission arrangement is designed for contactless transmission of signals between the first and second coupling part.

[0058] According to one embodiment, the second coupling part has at least one contact unit that is connected to the transmission arrangement.

[0059] According to one embodiment, a water hose has a first coupling part of a quick-release coupling device at its first end and a second coupling part of a quick-release coupling device at its end. The two coupling parts can be coupled together and are freely rotatable relative to each other when coupled. The first coupling part is equipped with a valve. The second coupling part can also be equipped with a valve.

[0060] The water hose can thus be connected at its second end to, for example, a permanently installed first coupling and at its first end to a second coupling, such as a spout or another water hose. This makes it possible, for instance, to equip the mixing device with a first coupling to which the water hose is attached at its second end (second coupling). The water hose can then be connected to a permanently installed adapter, which, for example, has a first and second coupling. The second coupling of the permanently installed adapter is used to connect to the water hose, while the first coupling of the permanently installed adapter is used to connect a spout, as described above, or a shower hose.

[0061] Furthermore, the water hose can be designed as a shower hose and create a detachable connection between a permanently installed connection with a first coupling part and the outlet body designed as a hand shower with a second coupling part.

[0062] This allows for the creation of a modular system based on quick-coupling devices.

[0063] The hose can have signal lines, as described above. The coupling parts then have the corresponding transmission arrangements or contacts that are connected to the signal lines.

[0064] The water outlet assembly, quick-coupling device, and sanitary fixture described here can be used in both private and public settings. For example, sanitary facilities in hotels or restaurants can be equipped with such water outlet assemblies. Furthermore, these water outlet assemblies can be used in industrial or medical environments. In particular, the ease of replacement, decoupling, and spatial separation of the water outlet and mixing device, the avoidance of steps, edges, or joints in the outlet area and the resulting ease of cleaning, as well as the quick coupling and uncoupling capability with automatic shut-off of the inlet, are some of the advantages that enable their use in these areas.Secondly, the installation effort is reduced, as it is not necessary to install cold and hot water pipes up to every outlet (faucet).

[0065] The embodiments described above can be combined with each other as desired. Brief description of the characters

[0075] Fig. Figure 8 shows a water outlet arrangement according to a further embodiment. Examples of implementation

[0076] The embodiments described here relate to a water outlet arrangement which is equipped with a quick coupling and which allows assembly and / or disassembly without tools by means of a spring-loaded coupling system.

[0077] Assembly is achieved through an axial movement that connects the two coupling parts and also decouples them again by means of an axial movement.

[0078] According to the embodiments described here, the water outlet arrangement is fully rotatable and pivotable in the coupled and operational state, since the two coupling parts ensure free rotation in the coupled state.

[0079] During disassembly, the water supply is shut off on the inlet side (intrinsically safe). The water outlet assembly can have at least one contact, for example electrical / optical / inductive, for transmitting electrical, electromagnetic, optical and inductive signals.

[0080] The water outlet assembly comprises a quick-release coupling, preferably made of stainless steel, brass, plastic, or a mineral or glass material, and the actual outlet body, which can be made of the same or different materials and in any shape suitable for water discharge. The resulting outlet assembly, consisting of the quick-release coupling and the outlet body, can be made of chrome-plated or painted brass, stainless steel, or plastic, ceramic, glass, or mineral materials. This outlet assembly can also be custom-made using additive manufacturing processes, also known as 3D printing, and then assembled with the quick-release coupling. The outlet body can be used, for example, as a water outlet on a washbasin, within a shelf or console, above a washbasin or bathtub, and also as a shower head.All these outlet bodies can contain sensors and buttons that control / regulate the outlet volume, pH value, temperature and / or time-based algorithms for the water flow.

[0081] Fig. Figure 1 shows a sanitary installation using the example of a washbasin. 110 At the sink 110 is a discharge body 190 in the form of a water outlet that can be designed as desired, via a quick-release coupling or plug-in coupling 150 with a water inlet or mixed water inlet 125 connected. The quick coupling 150 This forms the quick-release coupling device. The term "quick-release coupling" will be used hereafter.

[0082] The outlet body 190 forms together with the quick coupling 150 a water outlet arrangement 100 The outlet body 190 It can be formed in any desired shape. Typically, the outlet body has 190 a flow channel 192on, which is from the quick coupling 150 to a drain opening 191 leads.

[0083] The mixed water inlet 125 connects the quick coupling 150 with a mixing device 120 , which are located below the sink 110 or can be installed behind a wall. The mixing unit 120 can have at least two inlets 121 and 122 They typically have features for hot and cold water. In addition to at least one central mixed water inlet, they also have a central mixed water supply. 125 for quick coupling 150 can the mixing device 120 further inflows 123 , 124 for other sanitary facilities. From the perspective of the mixing unit 120 The milk water inlet 125 for quick coupling 150 This represents a mixed water outflow, as the mixed water here comes from the mixing device. 120 flows away. Therefore, these terms will be used synonymously below.

[0084] The mixing device 120 can at least one tax input 126a exhibit, for example via a signal line 126 with contacts of the quick coupling 150 It can be electrically connected. This allows control signals to be sent from an operating unit of the outlet body. 190 , as described below, for the mixing device 120 and in particular to a control device located therein 127 be conducted.

[0085] Furthermore, the mixing device 120 at least one sensor (transducer) 129 as well as a communication device 128 for contactless and / or wired communication with a remote query device, a maintenance device, or a central control and monitoring unit. The sensor 129 , or the sensors 129 , can use the communication device 128and / or the control unit 127 be coupled.

[0086] Remote monitoring can be used, for example, to record and transmit the amount of water consumed, separated into hot and cold water. The current usage status can also be queried, for instance, to centrally generate a signal when the water supply is no longer in use or has been open for longer than a predefined period. This can be advantageous in nursing homes, for example, to ensure that residents are healthy and that the water supply has not been accidentally left open, thus preventing water damage.

[0087] According to one embodiment, a camera and / or scanner can also be integrated into the dispensing body, which scans or photographs body parts (hand, skin, arm, etc.) and then transmits the data remotely. This can be used, for example, for diagnostics, such as in traditional Chinese medicine, or for measuring the pH value on the skin and / or body temperature, as well as other physiological parameters.

[0088] The control unit 127 can therefore directly connect to the communication device 128 for such remote inquiries.

[0089] The mixing device 120 It also has valves (not shown here) for mixing hot and cold water. These valves are preferentially controlled by the control unit. 127 controlled, which simultaneously regulates the respective water quantities to maintain a predetermined water temperature at the mixed water inlet. 125This enables. Furthermore, the control unit can 127 have facilities for processing algorithms for the temporal control of water flow and temperature in order to regulate the flow rate and water temperature according to a predetermined time profile.

[0090] The mixing unit 120 It can also be used for any mixed water inlet. 123 , 124 , 125 Control individually or in groups and regulate or control the respective flow rate and temperature individually or in groups.

[0091] Fig. Figure 2 shows a quick coupling according to one embodiment. 200 in the form of a plug-in coupling that is integrated into a sanitary facility.

[0092] The quick coupling 200 includes a first coupling part 210 and a second clutch part 220 The first clutch part 210 is permanently installed here, for example in a sink205 a sanitary facility. The first coupling part 210 It then protrudes vertically from the surface of the sink. 205 out. It is also possible that the first clutch part 210 integrated into a wall or console and installed, for example, horizontally or at an angle.

[0093] The first clutch part 210 includes a hollow coupling pin 211 , an inlet-side connection 212 and a flange 213 , which in this embodiment is located between the coupling pin 211 and the inlet-side connection 212 is arranged. A flow channel 214 centrally penetrates the first coupling part 210 The inlet-side connection 212It can be designed as a threaded connection for receiving a permanently installed water pipe, for mounting on a washbasin, shelf, console or bathtub, or for connecting to a hose, for example by means of an adapter.

[0094] The second clutch part 220 includes a body 225 , in which a coupling pin receptacle 221 is formed. At the same time, the coupling pin receptacle forms 221 also a flow channel 224 in the second clutch part 220 .

[0095] The two coupling parts are used for coupling. 210 , 220 along a coupling axis, indicated here by the dotted line, the two parts move towards each other. In doing so, the coupling pin... 211 into the coupling pin receptacle 221 inserted until a point on the outside of the coupling pin 211 arranged spring-loaded locking element 241into a space on the inside of the coupling pin receptacle 221 intended locking element receptacle 242 intervenes. This involves the movement of the locking element. 241 typically radially outwards. It is also possible to arrange the locking element differently. 241 on the inside of the coupling pin receptacle 221 and from the locking element mount 242 on the outside of the coupling pin 211 to be provided. Then the movement of the locking element takes place. 241 when snapping into place, radially inwards.

[0096] The coupling axis typically runs in the axial direction of the two coupling parts.

[0097] As a locking element 241 or locking elements 241 Spheres or pins with rounded tips are particularly suitable. This is achieved through the shaping of the locking element. 241 and locking element holder 242The force required for coupling and uncoupling can be adjusted by changing the spring preload strength. This also contributes to the safety of the quick-release coupling.

[0098] To uncouple, only the second coupling part needs to be removed. 220 can be pulled off along the coupling axis by overcoming a definable resistance.

[0099] When coupled, the second coupling part 220 completely free against the first coupling part 210 rotatable, since the locking element 241 in the surrounding locking element holder 242 can follow the rotation without losing the clutch effect.

[0100] To ensure free rotation, it is sufficient if the coupling pin 211 an essentially circular cylindrical outer cross-section and the coupling pin receptacle 221 It has an essentially circular cylindrical inner cross-section. The outer shape of the second coupling part220 It does not necessarily have to be circular or cylindrical, nor rotationally symmetrical. However, a rotationally symmetrical outer shape is preferred. In the embodiment shown here, the body is 225 of the second clutch part 220 frustoconical.

[0101] The locking mechanism of the two coupling parts 210 , 220 preferably via spring-loaded balls 241 , which are in the first clutch part 210 stored and inserted into the locking element receptacle designed here as a circumferential groove 242 in the second clutch part 220 engage. To uncouple, the second coupling part is used. 220 then axially against the spring resistance of the springs which hold the balls 241 into the groove 242 press, pulled off.

[0102] Both clutch parts 210 , 220 have valves or valve inserts 230 , 280 , which are located in the respective flow channels 214 ,224 are used and seal them.

[0103] The valve 230 The first clutch part has a valve body 231 up, which is under a spring element 234 generated preload in the direction of the second coupling part 220 against a valve seat 232 is pressed. A replaceable seal may be required. 233 , for example in the form of a ring seal, on the valve body 231 be arranged, which are then from the valve body 231 against the valve seat 232 is pressed. The valve body 231 It also features a valve tappet. 236 up, which leads towards the second coupling part 220 points.

[0104] The valve 280 in the second clutch part 220 is in a valve insert 285 housed, which leads from the first coupling part 210 far side of the flow channel 224It may, for example, be screwed into or pressed into these. The valve 280 also features a valve body 281 up, which is equipped with a spring element 284 , which is against the valve insert 285 supported, in the direction of the first coupling part 210 against a valve seat 282 is pressed. A ring seal or other sealing element can also be used here. 283 between the valve seat 282 and the valve body 281 be planned.

[0105] In the second clutch part 220 is therefore an insert or valve insert 285 provided for, which in the direction of flow has a spring-loaded closure or valve 280 to protect against backflow from downstream to the second coupling part 220 The water it contains is used for this purpose. When axially merging the second coupling part. 220 with the first clutch part 210The upper valve insert presses 285 by means of its valve body, which is pre-tensioned in the direction of clutch movement 281 against the valve tappet 236 in the first clutch part 210 In this process, both valve bodies press against each other. 231 , 281 from their respective valve seats 232 , 282 out and open their respective flow channels 214 , 224 This reduces the flow rate in the first coupling part. 210 released. At the same time, the pressure exerted by the valve tappet is overcome. 236 moving valve bodies 281 the spring force in the valve insert 285 and also provides the flow channel here 224 free. The flow channels thus opened 214 , 224 This forms a common, continuous flow opening. The water can now pass through the quick coupling. 200 flow through.

[0106] By means of the respective set spring force of the spring elements 234and 284 open the valves 230 , 280 simultaneously or one after the other.

[0107] As in Fig. 2. As can be seen, the valve insert 285 at its first clutch part 210 The pointing side has a pin-like outer shape to guide it into the flow channel. 214 of the first clutch part 214 to be able to intervene.

[0108] The valves 230 and 280 are also preferably rotationally symmetrical in design.

[0109] The quick coupling 200 It also includes a transfer order. 250 , for example to transmit electrical signals between the two coupling parts 210 , 220 to exchange. The transmission arrangement can enable optical, resistive, galvanic, inductive, or electromagnetic signal transmission.

[0110] This can be done in the second coupling part. 220for example, connecting contacts in a ring groove 255 be arranged around the perimeter of the first coupling part 210 The facing side is formed. The first coupling part 210 It also has connecting contacts, for example in the form of a raised contact ring. 251 , which fits into the ring groove 255 of the second clutch part 220 engages when both clutch parts 210 , 220 are coupled together. At the second coupling part... 220 The contact ring can be positioned on the pointing side 251 Several concentrically arranged contacts are present, which correspond to corresponding connecting contacts in the annular groove and engage with them in the coupled state. Due to the annular design of the annular groove 255 and contact ring 251 is the free rotation of the second coupling part 220 compared to the first clutch part 210This remains possible. This allows signal transmission in any rotational position.

[0111] Instead of a contact ring 251 can also be a contact pin 252 in the first clutch part 210 This is provided for in the lower part of the first coupling section. 210 presented as an alternative.

[0112] The contacts can also be spring-loaded to ensure a secure electrical contact.

[0113] It is advantageous if the contacts are on the side of the first coupling part. 210 raised above the flange 213 are and into the ring groove 255 or engage in another suitable recess. This largely protects the contacts. Is the first coupling part 210 for example, vertically in a sink 205or similar integrated components, the contacts are located above the surface of the washbasin. Additional seals can also be provided for further protection.

[0114] Fig. 3 shows the quick coupling 200 out of Fig. 2 in a perspective view. The arrangement of the ring groove is particularly noticeable here. 255 with the internal contact rings. The quick-release coupling is shown here in an unassembled state, i.e., the first coupling part. 210 is not attached to a sanitary facility.

[0115] The valve 230 is used as an insert for the second coupling part 220 pointing side into the flow channel 214 inserted, i.e. into the coupling pin 211 inserted and, for example, pressed or screwed into it.

[0116] Fig. Figure 4 shows a water outlet arrangement according to a further embodiment. The quick-release coupling used here essentially corresponds to the one described in the Fig. 2 and Fig. The 3 quick couplings shown are used, so only the differences are explained.

[0117] The water outlet assembly forms an outlet set comprising three parts, namely the first coupling part. 210 , the second clutch part 220 and a discharge body 290 , which is connected to the second coupling part 220 is detachably connected.

[0118] The in Fig. 5 shown outlet bodies 290 It can consist of one or more parts. Specifically, in this embodiment, it consists of a base body. 290a and an outlet 290b The basic body 290a has a recording or recording room 295 for the preferably complete absorption of the second coupling part 220The recording 295 is in Fig. 5 clearly visible. The inner shape of the recording 295 can be adjusted to the outer shape of the second coupling part 220 can be adapted. For example, the second coupling part can be adjusted. 220 into the recording 295 They are inserted in a rotationally secure manner and secured within it by means of fixing elements. 293 , for example, in the form of screws. To ensure a rotationally fixed connection between the second coupling part 220 and the outlet body 290 To improve the connection, positive-locking connecting elements, such as longitudinal grooves and ribs extending in the axial direction, can be provided. These also ensure a precise relative position of the second coupling part. 220 and basic body 290a to each other, which is advantageous for the electrical connection, as described below.

[0119] The outlet body 290It can therefore generally be connected to the second coupling part by means of screws or plug and / or screw connections. 220 be connected.

[0120] It is also possible that the second clutch part 220 into the outlet body 290 It is glued in place. However, the second coupling part can then be replaced without any problems. 220 , or the outlet body 290 , only conditionally given.

[0121] About seals 294 A seal is formed between the second coupling part. 220 and basic body 290a The basic body 290a and the run 290b Each has a central bore or opening that is coaxial with the flow channel. 224 in the second clutch part 220 are and together form a channel 292 in the outlet body 290 form, which leads to the outlet opening of the outlet body, not shown here 290 leads.

[0122] Alternatively, it is also possible that the second clutch part 220 into the basic body 290a It is screwed in. To ensure a rotationally secure connection here as well, additional fixing elements are also used. 293 used.

[0123] As in Fig. 4. The second coupling part is recognizable. 220 via a ring groove 264 with internal ring contacts 261 , 262 and 263 The number of contacts is not limited to three, but can also be two, four, or more. Of the individual ring contacts... 261 , 262 , 263 electrical lines, for example in the form of a cable, lead to a contact unit 256 , located on the outside of the second coupling part 220 is arranged and has an electrical contact with the base body 290a mediated. The contact unit 256 This includes contact elements in the second coupling part. 220and corresponding contact elements in the base body 290a These are connected via electrical wires. 258 , for example in the form of a cable, with individual controls 271 , 272 , 273 a control unit 270 tied together.

[0124] The control unit 270 is on the outside of the outlet body 290 , specifically here the basic body 290a arranged, for example, in the material of the base body 290a integrated. The controls 271 , 272 , 273 The control unit can consist of switches, for example membrane switches, or areas of a touch-sensitive surface, for example also in the same material as the outlet body itself or a glass or plastic surface.

[0125] The control unit 270 is thus by means of the transmission arrangement 250 , which the ring groove 264with the ring contacts 261 , 262 , 263 on the side of the second coupling part 220 and the contact ring 251 on the side of the first coupling part 210 includes, and a signal line 226 with the mixing unit (not shown here). The mixing unit can therefore be conveniently operated directly by touching or pressing the control unit. 270 They can be controlled, for example to adjust the water temperature and the amount of water flowing through.

[0126] An alternative transmission arrangement 250a is in the lower part of the image Fig. 4 shown. This transmission arrangement 250a enables contactless signal transmission through inductive coupling of a concentric connection to the coupling pin 211 coil 269 on the first clutch part 210 with a concentric coupling pin receptacle 221 coil 268in the second clutch part 220 The coil 269 When the clutch is engaged, it enters the ring groove. 267 to lie down and therefore lies on the coil 268 directly opposite each other. This results in good inductive coupling. A benefit of this design is that the coils 268 , 269 They can be completely encapsulated, so there are no bare contacts in the coupling area.

[0127] By means of the transfer order 250a It is not only a signal transmission but also a supply of electrical energy from the first coupling part. 210 to the second clutch part 222 Possible. Energy transmission can occur at a comparatively low frequency, unlike signal transmission.

[0128] Alternatively, the transmission arrangement can also enable optical signal transmission. For example, instead of the coil... 268An acrylic or glass ring is integrated to guide the optical signal from a transmitter on the first coupling part to a receiver, regardless of the rotational position of the two coupling parts. The glass ring, for example, is positioned relative to the ring groove. 267 free so that optical coupling from a transmitter 269 For example, an LED, OLED, or laser can be used. It is also possible to incorporate an acrylic ring, glass ring, or similar component on the first coupling part or on both. In the case of an optical transmission arrangement, the signal line is an optical fiber. The advantage of using an optical transmission arrangement is that no current flows. Since no high-frequency signals need to be transmitted, but only control signals in, for example, the kHz range, the quality of the optical coupling is comparatively uncritical.

[0129] Alternatively, signal transmission can be achieved using radio technology based on WLAN, Bluetooth, or transponder technology. This allows for integration into a wireless central home control system or remote access system.

[0130] To transmit the signals and / or energy from the second coupling part 220 on the outlet body 290 To transfer, one can also be used with the transfer order. 250a connected contact unit 257 as described above. The electronics used for signal generation 266 , which is then also supplied with energy, is connected via a cable 259 with the contact unit 257 tied together.

[0131] Fig. Figure 4 shows a further alternative regarding the attachment of the first coupling part. 210 This one has its flange. 213 to the top of the sanitary facility 205attached and intersected with the inlet-side connection 212 an opening in the sanitary facility 205 The inlet is then connected from below to the inlet-side connection. 212 screwed together and the first coupling part 210 so that at the sanitary facilities 205 fixed.

[0132] Furthermore, seals can 218 on the first clutch part 210 , alternatively or additionally also on the second coupling part 220 , be ordered.

[0133] The outlet body 290 It can be made of a suitable material, for example metal, plastic, glass, ceramic, or a mineral composite. It is also possible to make the base body 290a made of one material and the outlet 290b to shape from a different material.

[0134] Fig. 5 shows the in Fig. 4 Water outlet arrangement with inductive coupling shown in a perspective exploded view, but without attachment to a sanitary fixture.

[0135] Fig. Figure 6 shows another embodiment of a water outlet arrangement, here using the example of a hand shower which is connected to a hose via a quick coupling. 301 is connected.

[0136] The design of the quick coupling can basically be the same as described above and includes a first coupling part. 310 and a second clutch part 320 The first clutch part 310 It has a thread to which a hose can be attached. 301 using an adapter 302 It is screwed on. The adapter 302 It also provides an electrical contact between the signal line routed in the hose wall. 326 and the contact element 351 or the coil 369 here.

[0137] The quick coupling can therefore either be connected via a contact-based transmission arrangement. 350 with contact ring 351 on the first clutch part 310 and ring groove 364 with ring contacts 361 , 362 , 363 on the second clutch part 320 , or via a contactless transmission arrangement 350a with coil 369 on the first clutch part 310 and ring groove 367 and coil 368 on the second clutch part 320 Available. Alternatively, optical transmission arrangements can also be used. Likewise, appropriate contact units can be used. 356 or 357 or optical contact units may be provided.

[0138] The hose 301 can at least one signal line 326 have a first coupling part at its first end 310 with transmission arrangement and a second coupling part at its second end 320with a corresponding transmission arrangement. The signal line 326 then connects the transmission arrangements of the coupling parts 310 , 320 This makes it possible to connect the hose. 301 In addition to the water connection, a signal connection and / or power supply can also be established. If all coupling components are equipped with coordinated transmission arrangements, signal transmission can be easily achieved even with a modular sanitary installation.

[0139] The signal line 326 It can be designed as a simple wire, multiple cable, stranded wire, foil, single or multiple wire braid, or optical fiber. Fig. Figure 6 shows the signal line, for example, as a wire. Fig. 7, on the other hand, is a version of the signal line. 326 shown as a metal mesh or conductive plastic mesh.

[0140] In addition, one or more measuring transducers (sensors) can be used. 399 , a camera and / or scanner in the second coupling part 220 and / or in the outlet body 390 It is also possible to install one or more sensors in the first coupling part. 310 to provide. The sensors 399 can either be equipped with electronics 366 or via a line or cable 359 , the transfer order 350 , 350a and signal line 326 be connected to the control unit in the mixing device.

[0141] The sensor(s) can also be provided with a permanently installed first coupling part, either in the first or second coupling part or in the outlet body.

[0142] Alternatively, signal transmission can be achieved using radio technology based on WLAN, Bluetooth, or transponder technology. This allows integration into a wireless central home control system or remote access system. For example, a communication device can be used for this purpose. 398 to be provided, for example in the outlet body 390 or also in the second clutch part 320 It can be integrated. The communication device 398 In addition to remote querying, it can also be used to transmit control signals to the mixing unit. It also serves to supply power to the communication unit. 398 Inductive coupling through the transmission arrangement is also a viable option. 350a this is because it allows for a comparatively simple and reliable energy transfer.

[0143] In the outlet body 390 is still a control unit 370 with controls 371 ,372 , 373 arranged, for example via cables 358 with the contact unit 356 and / or communication device 398 It can be connected. This makes it possible to control the water supply and water temperature directly via the controls. 371 , 372 , 373 to control.

[0144] The outlet body, for example designed as a shower head 390 can use one or more contacts (as part of the contact-based transmission arrangement) 350 or the contactless transmission arrangement 350a) for signal processing or signal transmission. All outlet bodies described here can contain sensors and buttons that control / regulate the flow rate, temperature, and / or timing algorithms for the water flow. The sensors can be mounted anywhere on the shower head. Preferably, however, on the side facing the inside of the shower head, as this enables ergonomic one-handed operation.

[0145] The outlet body designed as a hand shower or shower head 390 is, as described above, connected to the second coupling part 320 connected. The outlet body 390 It also features a flow channel. 392 on, which is in fluidic connection with the flow channel of the second coupling part 320 stands.

[0146] As described above, the outlet body 390It can be one-piece or multi-piece, and constructed from one or more materials. It can be made of chrome-plated or coated brass, stainless steel, plastic, ceramic, glass, or a mineral composite. Additive manufacturing processes can also be used to create free-form shapes for the outlet body. 390 , or parts thereof, may be used.

[0147] Fig. Figure 7 shows the water outlet arrangement according to Fig. Figure 6 shows a perspective view for better illustration, where the metal mesh of the hose is visible. 301 simultaneously as a signal line 326 serves.

[0148] Fig. Figure 8 shows another embodiment of a water outlet arrangement, which differs from that of the Fig. 6 and Fig. 7 differs essentially only in that the transmission arrangement 350 here directly between the first clutch part 310 and the outlet body 390It is formed. Therefore, no more signals are transmitted via the second coupling part. Therefore, there is also no contact unit. 356 , 357 between the second clutch part 320 and outlet body 390 necessary.

[0149] The electrical signal transmission between the first coupling part 310 and outlet body 390 It can be done with or without contact. In the latter case, for example, a coil is placed in the outlet body. 390 integrated.
