Description

[0001] Construction kit for a sanitary installation and sanitary arrangement

[0002] The invention relates to a kit for a sanitary installation, with valves, each valve having an interface for attaching a manual operating element.

[0003] The invention further relates to a sanitary arrangement, for example a changeover and / or closing device or sanitary installation, with at least two valves.

[0004] A modular system for plumbing installations, for example, allows plumbing fixtures to be adapted as needed and to a specific installation location, such as in a piece of furniture, without the need for special components. This creates a simple and cost-effective way to cover many different applications with just a few different components.

[0005] The object of the invention is now to expand the area of ​​application of such a kit and such a sanitary arrangement.

[0006] This object is achieved by a construction kit having the features of claim 1 and a sanitary arrangement according to claim 16.

[0007] The modular system according to the invention is therefore characterized in that a duplicating device is provided which is designed to be coupled to the interfaces of at least two valves in order to transmit a common manual actuation to the at least two valves. This makes it possible to switch several valves with just one manual actuation. In one embodiment, the duplicating device has mechanical guide means for guiding an actuation movement. In this way, the actuation movement is predetermined or at least stabilized.

[0008] In one embodiment, the duplicating device has at least two counter-interfaces, each of which can be coupled to an interface of a valve. This makes the valves variable and versatile.

[0009] It is particularly advantageous if the at least two mating interfaces are identical to one another and / or allow interchange of the connected valves and / or the interfaces can be reversibly detachably and / or permanently connected to the mating interfaces. In this way, the modular system offers maximum flexibility in use, since a wide range of applications can be covered with just a few components.

[0010] In one embodiment, the duplication device has a mechanical branch. This allows for mechanical actuation of multiple valves. The mechanical branch can be designed, for example, for push or pull actuation.

[0011] In one embodiment, the multiplication device has a fluid branch. This allows hydraulic or pneumatic actuation of several valves.

[0012] In one embodiment, the duplicating device has an electrical branch. This allows electrical actuation of several valves.

[0013] In one embodiment, the duplicating device is configured to transmit the manual actuation simultaneously, in particular to all valves. In this way, all valves are switched simultaneously and synchronously.

[0014] Alternatively, in one embodiment, the multiplication device can be configured to transmit the manual actuation to at least one valve with a time delay, wherein the time delay relates to the actuation of the other valves by the multiplication device. In this way, it is possible, for example, to allow a fluid flow to increase or stop more smoothly. This can, in particular, prevent a pressure surge during the closing process, which occurs when large volumes of water are decelerated quickly.

[0015] Independent of the time at which the individual valves are triggered, a time delay can also be implemented compared to manual operation.

[0016] In one design, the valves each feature a push-push mechanism. It is particularly advantageous if a mechanical branch is provided for pressure actuation.

[0017] In one embodiment, the duplicating device converts a jointly acting actuating movement into two individual actuating movements, in particular synchronously or at different times and / or of the same type, each of which acts on only one of the at least two valves. In this way, a valve can be used universally, since the valve is always actuated in the same way, regardless of whether the valve is actuated alone or jointly with other valves via a duplicating device.

[0018] In one embodiment, the jointly acting actuating movement and the individual actuating movements are of the same movement type, in particular linear actuating movements. This enables simple and cost-effective implementation and duplication of the movement.

[0019] In one embodiment, the valves comprise a main valve and a pilot valve, with the pilot valve controlling the main valve. The advantage here is that actuation of the pilot valve requires only a small amount of force, allowing the duplicating device to be of simple design.

[0020] In one embodiment, the multiplication device can be coupled to the pilot valve. It may be advantageous if the multiplication device has a fluid branch, with mechanical actuation. This means that the multiplication device directs the fluid flow to two pilot valves, thus switching the two main valves.

[0021] In one embodiment, the valves are of a uniform valve type. In particular, the type of branching is uniform, which makes the duplication device simpler to design.

[0022] In one embodiment, the duplication device is configured for coupling to at least one valve of a first valve type and to at least one valve of a second valve type. Thus, different valve types can be switched using one duplication device, thereby reducing the number of necessary components in the modular system. A first valve type can be, for example, a switching valve; a second valve type can be, for example, a diaphragm valve with a pilot valve or a piston valve.

[0023] In one embodiment, the valves of the first valve type correspond in the interface to the valves of the second valve type.

[0024] Alternatively, the valves of the first valve type may differ from the valves of the second valve type at least in their interface.

[0025] In one embodiment, the valves feature a thermostatic element. This can be particularly advantageous if, for example, the valves are used to control the hot and cold water supply in an on / off manner. This allows the temperature to be adjusted.

[0026] In one embodiment, a functional sanitary installation that can be constructed from the kit has fewer, preferably identical, valves and / or fewer valve types than the kit.

[0027] The invention further relates to a valve body with at least two valve receptacles, whose fluid connections are connected in pairs. It is advantageous that at least two valves can be switched in a fluid switching function.

[0028] For example, this can be achieved by appropriately forming channels.

[0029] The fitting body can, for example, be part of the modular system already described.

[0030] The invention further comprises a sanitary arrangement, in particular a sanitary fitting, sanitary diverter and / or closing device, or sanitary installation, with at least two valves, which is characterized in that a duplication device is provided which is coupled to the at least two valves, in particular to interfaces for fastening a respective manual actuation element, in order to transmit a common manual actuation simultaneously to the at least two valves. In this way, the at least two valves can be triggered by one actuation process.

[0031] Valves can be limited in their flow rate, for example by their geometry, by internal pipe cross-sections and / or by their operating principle.

[0032] In one embodiment of the sanitary arrangement, it is therefore advantageous if the at least two valves act fluidly in parallel, in particular wherein a fluid flow is split upstream of the at least two valves and / or combined downstream of the at least two valves. As a result, the flow rate can be doubled or increased by connecting two or more valves in parallel. However, thanks to the duplication device, only one manual actuation is necessary. A user thus does not recognize the presence of multiple valves.

[0033] It may be advantageous if the multiplication device actuates the valves with a time delay so that the fluid flow increases gradually and does not start immediately at maximum strength.

[0034] Alternatively or additionally, it can be provided that the duplication device actuates the valves with a time delay, so that the fluid flow decreases gradually and, for example, is not immediately reduced to the maximum strength or is stopped completely.

[0035] In one version of the sanitary arrangement, the

[0036] Duplicating device mechanical guide means for guiding an actuating movement on .

[0037] In one embodiment of the sanitary arrangement, the duplication device has at least two counter-interfaces, each of which can be coupled to an interface of a valve, in particular wherein the at least two counter-interfaces are identical to one another and / or allow an interchange of the coupled valves and / or wherein the interfaces can be reversibly detachably and / or permanently connected to the counter-interfaces.

[0038] In one embodiment of the sanitary arrangement, the duplicating device comprises a mechanical, fluidic or electrical branching.

[0039] In one embodiment of the sanitary arrangement, the duplication device is designed to transmit the manual operation simultaneously, in particular to all valves, or to at least one valve with a time delay.

[0040] In one version of the sanitary arrangement, the valves have a push-push mechanism.

[0041] In one embodiment of the sanitary arrangement, the duplication device converts a jointly acting actuating movement into two, in particular synchronously running and / or similar, individual actuating movements, each of which acts only on one of the at least two valves (3).

[0042] In one embodiment of the sanitary arrangement, the jointly acting actuating movement and the individual actuating movements are of the same movement type, in particular linear actuating movements. In one embodiment of the sanitary arrangement, the valves have a main valve and a pilot valve.

[0043] In one embodiment of the sanitary arrangement, the duplication device can be coupled to the pilot valve.

[0044] In one embodiment of the sanitary arrangement, the valves are of a uniform valve type.

[0045] In one embodiment, the sanitary arrangement has valves of a first and a second valve type, wherein the duplication device is designed to be coupled to at least one valve of the first valve type and to at least one valve of the second valve type, in particular wherein the valves of the first valve type correspond to the valves of the second valve type in the interface or wherein the valves of the first valve type differ from the valves of the second valve type at least in their interface.

[0046] In one embodiment of the sanitary arrangement, at least one valve has a thermostatic element.

[0047] In another embodiment, a valve has a mixing device for mixing hot and cold water. This allows the functionality of a sanitary fitting constructed using the modular system to be expanded.

[0048] In one embodiment, the sanitary arrangement is formed from a modular system according to the invention, in particular wherein the sanitary arrangement has fewer, preferably identical, valves and / or fewer valve types than the modular system.

[0049] Finally, the invention also encompasses the use of two valves connected in parallel to control a water flow in a sanitary installation. Thus, an increased flow rate can be achieved without the need for special valves.

[0050] In particular, a common manual operation can be transmitted simultaneously to at least two valves. This simplifies operation. The use of two or more valves to control an (increased) flow can thus be achieved unnoticed by the user.

[0051] In particular, a construction kit according to the invention can be used for this use, for example as described above and / or according to one of the claims directed to a construction kit.

[0052] Alternatively or additionally, this use can be provided in a sanitary arrangement according to the invention, for example as described above and / or according to one of the claims directed to a modular system.

[0053] The invention is explained in more detail below using exemplary embodiments with reference to the accompanying drawings.

[0054] It shows:

[0058] Fig. 4 shows another sanitary arrangement with two parallel valves for increasing a flow rate, which is assembled using the modular system

[0059] Fig. 5 is a schematic front view of a sanitary arrangement according to Fig. 4 with a fitting body, and

[0060] Fig. 6 is a schematic side view of the valve body of Fig. 5.

[0061] Fig. 1 shows a sanitary construction kit 1 which is designed to form a sanitary functional arrangement 15 by connecting the desired components of the sanitary construction kit 1 to one another according to assembly instructions.

[0062] In Figs. 2 and 3, several embodiments of sanitary functional arrangements of a sanitary kit 1 according to the invention are shown, each of which is designated as 15.

[0063] The sanitary kit 1 comprises at least one outlet element 2 from which a fluid, in particular a water jet, emerges during use of a sanitary functional arrangement 15.

[0064] In order to be able to control the outlet from the outlet element 2, the sanitary kit 1 has at least one valve 3 and at least one connecting element 4, with which the outlet element 2 can be fluidly connected to the valve 3 or is connected in the assembled state.

[0065] The sanitary kit 1 comprises at least two, preferably functionally different, valves 3, which can be selectively fluidically connected to the outlet element 2 via the at least one connecting element 4. In addition to the valves 3, further control elements, such as a diverter 23, can also be present. The sanitary kit 1 has a distributor 5, to which two or more, preferably functionally different, valves 3 and / or connecting elements 4 and / or outlet elements 2 can be connected simultaneously or are connected in the assembled state.

[0066] To enable the simplest possible assembly, the at least one connecting element 4 is designed to be pluggable. To prevent a plugged connection from becoming loose, the at least one connecting element 4 and / or the component connected thereto can have a latching and / or locking mechanism to firmly connect the components to one another.

[0067] In order to be able to form a variety of differently designed sanitary functional arrangements 15, at least one connecting element 4 is designed to be variable in shape. Preformed connecting elements 4 and / or connecting elements 4 with different lengths may also be present.

[0068] The sanitary kit 1 has at least one connection element for connection to a supply connection 16 (in particular of a supply network). For a functional arrangement 15 that is designed to be connected to multiple supply connections 16 of a supply network or multiple supply networks, i.e. in particular a hot water connection and a cold water connection, one connection element can be provided per supply network, in particular per connection.

[0069] The sanitary kit 1 comprises at least one functional unit. The at least one functional unit can have one or more functions. Examples of these can be: at least one further valve 3, a sensor 6 and / or an actuator 7, for example a flow heater 8 and / or a power generator 9. The functional unit can be connected directly and / or indirectly via a connecting element 4 to the valve 3 and / or to the outlet element 2.

[0070] Furthermore, the sanitary kit 1 comprises at least two different, in particular differently shaped and / or differently long, connecting elements 4 with matching connections. This allows a user to select the connecting element 4 that best suits their installation needs.

[0071] The sanitary kit 1 comprises a plurality of fastening means 10 for fastening the at least one outlet element 2 and / or the at least one valve 3 and / or the at least one connecting element 4 to a functional carrier 11.

[0072] The sanitary kit 1 comprises at least one branching element 12, in particular a branching element 12 branching more than twice, with which at least one connecting element 4 can be selectively connected to form the distributor 5.

[0073] In order to be able to carry out manual control, at least one valve 3 has a manual control element 13. The manual control elements 13 of two different valves 3 have a matching outer contour and / or outer dimensions in order to be able to be used by a user optionally while requiring the same space.

[0074] In the example, some of the handheld control elements 13 have a mating interface 22, with which the handheld control element 13 is connected to an interface of a valve 3. The mating interface 22 can comprise a detachable connection, so that a handheld control element 13 can be connected to different valves 3.

[0075] In one example, at least two valves 3 can be designed as valves. The valves can have a continuous, multi-stage, or on / off flow rate control. The valves can be actuated mechanically, fluidically, or electrically.

[0076] The valves can be of a uniform valve type. Uniformity can refer to the type of flow control and / or actuation.

[0077] The modular system 1 further comprises at least one duplicating device 17. The duplicating device 17 may, for example, have an interface 14 for connection to a hand-held control element 13 or its counter-interface 22, or a hand-held control element 13 may be fixed, in particular integral, with the duplicating device 17.

[0078] Furthermore, the duplication device 17 has a branch 18 dividing into two or more branches 19, at each end of which a counter-interface 22 is formed. Via this counter-interface 22, each branch 19 of the duplication device 17 can be connected to the interface 14 of a valve 3. In this way, two or more valves 3 can be actuated by a single manual control element 13 via the duplication device 17.

[0079] In one embodiment, the duplication device is configured for simultaneous coupling to at least one valve of a first valve type and to at least one valve of a second valve type. Thus, different valve types can be switched using one duplication device, thereby reducing the number of required components in the modular system.

[0080] In one embodiment, the valves of the first valve type correspond in the interface to the valves of the second valve type.

[0081] Alternatively, the valves of the first valve type may differ from the valves of the second valve type at least in their interface.

[0082] It is also possible for different valve types with the same interfaces and other valve types with different interfaces to be present in a single module. The interfaces can indicate a possible combination of valve type and manual control element, thus preventing misuse.

[0083] Fig. 2 shows a first sanitary arrangement 15 formed from a modular system 1. The sanitary arrangement 15 has two supply connections 16, for example, hot and cold water.

[0084] Each supply connection 16 is connected to a valve 3 via connecting elements 4. The valves 3 are in turn connected to a mixer 20 via connecting elements 4, which in turn is connected to an outlet element 2.

[0085] The two valves 3 have interfaces 14 for connection to a manual control element 13. In this example, however, a branch 19 of a duplicating device 17 with its counter interfaces 22, which has a manual control element 13, is connected to each of the interfaces 14.

[0086] In this way, both valves 3 can be actuated simultaneously and synchronously with just one manual control element 13. The actuation can be mechanical, for example. The valves 3 can, for example, have diaphragm valves that can be switched via a pilot valve. Here, the duplication device 17 can, for example, mechanically actuate a push-push mechanism. However, the duplication device 17 can also be connected downstream of a push-push mechanism and contain a branch of the fluidic control line that controls the pilot valve, so that the actuation takes place mechanically, but the branching is fluid.

[0087] In addition, numerous other combinations of actuation and branching effects are conceivable and possible, not all of which can be listed here. Therefore, the application is in no way limited to the embodiments shown.

[0088] In the sanitary arrangement 15 of Fig. 3, a supply connection 16 is provided. A distributor 5 is connected upstream of the two valves 3, which distributes the water flow to two valves 3. Each valve 3 is connected to a manual control element 13 via a duplicating device 17, as in Fig. 2. Each valve 3 is fluidly connected to a separate outlet element 2.

[0089] Fig. 4 shows a sanitary arrangement 15 similar to Fig. 2.

[0090] The two supply connections 16 are connected to a mixer 20. The mixer 20 can additionally have a thermostatic element. The sanitary arrangement has a connecting element 4 with a large line cross-section or a large flow rate. A plurality of distributors 5 are arranged on this connecting element 4, which for the sake of clarity are shown here only as points on the connecting element 4. The distributor 5 leads to at least two (upper) valves 3, which can be actuated via a (respective) manual control element 13.

[0091] These two valves 3 are each connected to their own outlet element 2 .

[0092] Another distributor 5 is also connected to the two (lower) valves 3, which act in parallel in the fluid path.

[0093] On the downstream side, these two valves 3 are connected to an outlet element 2 via an inverted distributor 5 , which thus acts as a mixer 20 or combiner.

[0094] Thus, the fluid connections 21 of the lower valve receptacles 26 are brought together in pairs.

[0095] These two lower valves 3 are connected to a common manual control element 13 via a duplicating device 17. Therefore, both valves 3 can be operated with only one manual operation.

[0096] The lower valves can be switched on and / or off simultaneously or sequentially.

[0097] This outlet element 2 for the lower valves 3 can, for example, be a bath-filling fitting or a rain shower, or can be connected to one. The two (lower) valves 3 acting in parallel in the fluid path double the total flow rate through the valves 3, thereby enabling faster bath filling or a more complete shower experience. The duplication device 17 allows both valves 3 to be operated with just one manual actuation, so that the user cannot detect or notice the presence of two or more valves.

[0098] The first two valves 3 can, for example, control various outlet elements 2 with a lower flow rate, such as a shower head and / or a hand shower. In addition to the designs shown here, numerous other sanitary arrangements can be created from the modular system. The application is therefore not limited to the two designs shown.

[0099] Fig. 5 shows a schematic front view of an exemplary embodiment of a sanitary arrangement 15 according to Fig. 4. Fig. 6 shows a schematic side view of the lower valves 3 of the sanitary arrangement 15 of Fig. 5.

[0100] The sanitary arrangement 15 has a fitting body 24 with two (upper) valve receptacles 25 and two (lower) valve receptacles 26. The fitting body 24 can, for example, consist of a cast material, in particular metal, and can preferably be manufactured using a casting process. The fitting body 24 can, for example, be designed for flush mounting.

[0101] The fitting body 24 can also be an element of the modular system and serve, for example, as a base or functional carrier 11 for individual elements, especially valves, of the modular system.

[0102] Each valve receptacle 25, 26 has at least two fluid connections 21. The valve receptacles 25 and 26 have the fluid interfaces for connecting the valves 3. Within the valve body, the valve receptacles 25 and 26 can be fluidly connected by fixed channels, so that no additional hose connections are necessary within the valve body 24.

[0103] Two upper valves 3 are each arranged in one of the upper valve receptacles 25. The two upper valves 3 are each assigned to an outlet element 2, for example a shower head or a hand shower.

[0104] Two lower valves 3 are each arranged in one of the lower valve receptacles 26. The two lower valves 3 are fluidly connected in parallel. Within the valve body 24, the valve receptacles 26 are fluidly connected to one another via channels 4. Before and after the valve receptacles 26, the channels each contain a branch 5 which divides the fluid flow and reunites it. In this way, the flow rate can be doubled compared to one valve. The combined channel 4 leads to a common outlet element 2.

[0105] The two lower valves 3 are connected via a multiplication device 17 and can be operated jointly. The manual control 13 is connected via a branch 18 to two branches 19, each of which is coupled to the interfaces 14 of the two valves 3.

[0106] Preferably, the actuation of one of the two valves can be delayed so that the fluid flow does not start and end immediately at full strength.
