Description

[0001] The present invention relates to a sanitary installation for partitioning a shower area, comprising a number of functional modules configured for partitioning at least one shower area, and at least one mounting rail arrangement having a receiving section and a connection section connected to the receiving section. In its assembled state, the receiving section extends at least partially vertically along a longitudinal axis and is configured for coupling with at least one of the functional modules. The connection section is configured to be connected to a wall and / or ceiling via a distal wall- and / or ceiling-side connection. Furthermore, the sanitary installation includes at least one electrical device for providing a physical output.

[0002] In the field of sanitary installations, particularly in the area of ​​shower enclosures, it is common to use various functional modules to enhance functionality and comfort in bathrooms. Well-known systems typically comprise simple mechanical structures that serve to physically separate shower areas while meeting basic requirements for stability and watertightness. These systems are generally limited to mechanical functions and do not offer integrated electrical solutions that meet modern demands for comfort and functionality.

[0003] This is primarily due to the stringent safety requirements for electrical plumbing installations in the shower area, which aim to eliminate the risk of electric shock. The shower area, specifically the area above the shower / bathtub extending 2.25 meters upwards and within a 1.2-meter radius of the fixtures, therefore requires electrical plumbing installations with a minimum IP44 rating. However, for safety reasons, IP65-rated installations are generally used. This means that the installation must be water-resistant, completely dustproof, and protected against water jets from all angles (e.g., from pressure washers or showers).

[0004] According to established techniques, electrical appliances such as lighting or heating systems are often installed separately and not in the splash-prone area of ​​the shower. These appliances are typically not integrated into the shower enclosure structure, which limits the comfort of the shower area. Consequently, existing plumbing installations for shower enclosures are not designed to interact with modern smart home technologies, thus limiting automation and control options.

[0005] Furthermore, there are theoretical considerations regarding routing electrical cables for supplying appliances in the shower area through permanently installed wall elements of sanitary installations, as shown, for example, in DE 10 2019 124 877 A1. However, routing electrical cables connected to the household electrical grid, which typically operates at 230 V, appears to be only possible to a limited extent, if at all, in practice. There is also a need for flexible and customizable solutions for sanitary installations that nevertheless allow for the integration of electrical cables for supplying appliances.

[0006] Despite significant advances in sanitary engineering, there remains a need for innovative solutions that allow for the seamless integration of electrical appliances into shower enclosures. Such solutions should not only simplify plumbing installation but also improve safety and aesthetics. Furthermore, there is a growing demand for systems compatible with modern smart home technologies to enable user-friendly control and customization of functions.

[0007] Therefore, one of the technical problems underlying the present invention is to provide a sanitary installation that at least partially overcomes the disadvantages of known sanitary installations.

[0008] An objective of the present invention is to provide a sanitary installation that overcomes one or more of the disadvantages of the known sanitary installation.

[0009] The invention solves the underlying problem in a first aspect by means of a sanitary installation according to claim 1. With regard to a sanitary installation of the type mentioned above, the invention proposes that the mounting rail arrangement includes a power cable guided therein, which is at least indirectly connected to the electrical consumer. The room connection comprises a low-voltage connection, which is designed for the conductive connection of the power cable to a power line installed in the wall and / or ceiling for carrying current at a low voltage. Low voltage is defined as alternating voltages up to 1000 volts and direct voltages up to 1500 volts.

[0010] It should be understood that the power cable guided in the mounting rail arrangement has insulation.

[0011] One advantage of the invention lies in the integration of the electrical supply, i.e., the at least one power cable, within the mounting rail assembly, which enables flexible and safe cable routing for supplying electrical devices. The mounting rail assembly, capable of integrating both mechanical and electrical functions, offers a versatile solution for modern sanitary installations that are both aesthetically pleasing and functional. The ability to route the power cable safely and securely, without being affected by external influences, represents a significant advancement in the design of sanitary installations used in demanding environments. A further advantage is the simple connection of the power cables to the electrical wiring installed in the wall or ceiling via the low-voltage connection, which simplifies installation and maintenance.The mounting rail assembly is mechanically connected to a wall or ceiling in the bathroom via the room connection. This allows for a simple and splash-proof electrical connection via the integrated low-voltage connection. The power cable can be safely connected to the mains supply within the mounting rail assembly, thus increasing safety. Furthermore, the inventors utilized the insight that a cable-carrying mounting rail assembly, which, in addition to the room connection for mechanical attachment to the room structure, also features a low-voltage connection, provides a central element of the sanitary installation. This element can be used in combination with one or more different and individually configurable functional modules, always ensuring a reliable power supply.This allows for individual placement of the electrical device, such as an LED strip, which can be attached to the mounting rail assembly itself or supplied with low-voltage power via suitable electrical connections within the functional module. Functional modules can also be designed simply as a strip with a permanently integrated sanitary unit, such as a towel rack and / or a storage compartment. Alternatively, the functional modules can incorporate sanitary furniture in the form of benches, washbasins, chests of drawers, and the like.

[0012] According to a preferred embodiment, the mounting rail assembly is equipped with a number of fluid-tight cable guides. These fluid-tight cable guides offer the advantage of preventing the ingress of water or other liquids into the electrical wiring area, thus increasing the safety and longevity of the plumbing installation. One primary cable guide of the fluid-tight cable guides is specifically designed to be sealed distal to the low-voltage connection. This sealing feature ensures that the power cable can be routed safely and securely from the low-voltage connection to an electrical contact. This helps to maintain the integrity of the electrical connection and minimize potential hazards from moisture or other external influences.Protection against liquid ingress significantly increases the safety of the plumbing installation, as it minimizes the risk of short circuits or other electrical problems caused by water contact. The electrical connection ensures that the physical output provided by the electrical appliance can be reliably utilized. The combination of a low-voltage connection, linked to a power line installed in the wall or ceiling, and fluid-tight cable conduits enables an efficient and safe power supply to the electrical appliances within the plumbing installation.

[0013] According to a preferred embodiment, the electrical contact is formed in a wall of the primary cable tray, and the electrical contact provides a fluid-tight seal for the primary cable tray. Thus, the power cable is already housed in a protected, fluid-tight sealed space during the installation of the plumbing system, which simplifies handling. Integrating the electrical contact into the wall of the primary cable tray also allows for a compact design that is aesthetically pleasing and saves space. The fluid-tight seal of the primary cable tray also contributes to the overall ease of maintenance of the plumbing system, as it reduces the likelihood of damage from moisture ingress, resulting in less frequent repairs or component replacements.

[0014] Preferably, the wall in which the electrical contact is formed is an outer wall of the receiving section, and the power cable is a first power cable. The functional module forms, at least partially, a fluid-tight cavity enclosed by a module wall and includes a second power cable housed within this cavity. This second power cable is connected via an electrical inlet contact in the module wall to the electrical contact of the primary cable guide in the outer wall of the receiving section. The fluid-tight cavity in the functional module protects the second power cable from moisture and other environmental influences, thereby increasing the durability and reliability of the electrical connection.The electrical inlet contact in the module wall and the electrical contact in the outer wall of the receiving section enable a secure and easily manageable connection between the first and second power cables, simplifying the installation and maintenance of the plumbing system. This configuration offers the advantage of improved modularity and flexibility, as the functional modules can be easily replaced or expanded without requiring extensive modifications to the electrical wiring. Furthermore, the fluid-tight design of the cavity within the functional module enhances safety by minimizing the risk of short circuits or other electrical problems caused by moisture. The use of two separate power cables connected via an electrical contact allows for clear separation of the electrical lines, simplifying troubleshooting and repair in the event of a fault.

[0015] According to a preferred embodiment, the functional module comprises two parallel longitudinal sides which, in the assembled state, run parallel to the longitudinal extent of the mounting rail assembly. This configuration enables stable and secure attachment of the functional module to the mounting rail assembly by engaging one of the longitudinal sides with the receiving section. This arrangement ensures a reliable mechanical connection that holds the functional module in position while simultaneously allowing for easy assembly and disassembly. Alternatively, two parallel receiving sections may be provided, so that each longitudinal side engages with a receiving section. Preferably, the electrical inlet contact is integrated on the first longitudinal side of the functional module.This placement of the electrical inlet contact facilitates the electrical connection between the functional module and the mounting rail assembly, which contains a power cable. This arrangement enables the efficient and safe transmission of electrical energy, for example, to an electrical load integrated into the functional module. The electrical inlet contact on the longitudinal side of the functional module also offers the advantage of being protected from external influences, thus increasing the safety and longevity of the electrical connection.

[0016] According to a preferred embodiment, the first longitudinal side is received in a receiving groove of the receiving section. This receiving groove is designed to ensure a secure and stable fastening of the first longitudinal side. The electrical contact for the primary cable routing is provided in the outer wall within the receiving groove. This means that the electrical contact is integrated into the structure of the receiving groove, providing an efficient and space-saving solution. The electrical contact and the electrical inlet contact are interconnected within the receiving groove, ensuring a reliable electrical connection. This arrangement allows for simple and quick plumbing installation. Integrating the electrical contact into the receiving groove reduces wiring complexity and increases safety, as the electrical connections are protected and less susceptible to damage.Another advantage is the increased flexibility in the design and placement of the functional modules, as the electrical connection can be made regardless of the modules' position within the mounting groove. This allows for individual customization of the sanitary installation to the specific needs and requirements of the user. Integrating the electrical contacts into the mounting groove also contributes to the aesthetics of the sanitary installation, as there are no visible cables or connections.

[0017] Preferably, at least one functional module has an electrical outlet contact formed in the module wall, which is connected to the electrical inlet contact via a second power cable for conducting current. This specific configuration enables efficient and safe current flow within the functional module, as the electrical outlet contact serves as an interface that can direct the current flow to other components of the plumbing installation. The electrical outlet contact is strategically positioned in the module wall to ensure seamless integration and easy accessibility, thus facilitating the installation and maintenance of the plumbing system.

[0018] According to a preferred embodiment, the electrical appliance has an electrical connection that can be connected to the electrical contact and / or the outlet contact and / or the inlet contact. This connection is designed to receive low-voltage power, ensuring a safe and efficient energy supply. The electrical connection is designed to establish a corresponding connection to the relevant contact, simplifying installation and maintenance. This allows for a flexible and modular design of the plumbing installation, as functional modules can be easily replaced or added without requiring extensive electrical work.The consumer can also be arranged individually and thus, for example, be located on the first longitudinal side of the function modules, where the consumer connection is then connected to the electrical contact of the mounting rail arrangement, or be located on the second longitudinal side of the function modules, where the consumer connection is then connected to the outlet contact of the function module.

[0019] According to a preferred embodiment of the plumbing installation, the electrical contact and / or the consumer connection and / or the inlet contact and / or the outlet contact is designed as an electrical plug connector. An electrical plug connector allows for easy and quick connection and disconnection of the electrical components, which significantly simplifies the installation and maintenance of the plumbing installation. The use of plug connectors reduces the need for complex wiring work, thus shortening installation time and minimizing the risk of installation errors. Furthermore, plug connectors provide a reliable and stable electrical connection, which is crucial for the safe operation of electrical consumers and other components in the plumbing installation.The ability to easily plug and unplug electrical components also facilitates the replacement and expansion of the system, increasing the flexibility and adaptability of the plumbing installation. Another advantage of using plug connectors is improved safety, as these contacts are generally designed to ensure a secure and insulated connection, thus reducing the risk of short circuits or electrical accidents.

[0020] According to a preferred embodiment, the sanitary installation additionally comprises at least one printed circuit board (PCB) which is connected via a second power cable to a low-voltage connection of the room's electrical supply and can be connected via a control line to at least one control interface. A receiving compartment for the PCB is assigned to the functional module and / or the mounting rail assembly. The PCB serves as a central control unit that enables communication between the various electrical components of the sanitary installation. Connecting the PCB to the low-voltage connection ensures a safe and efficient power supply, which is necessary for the operation of the electrical appliances.The control line enables the transmission of control commands and signals between the circuit board and the control interfaces, allowing for precise control and adjustment of the plumbing system's functions. The mounting space for the circuit board within the functional module or mounting rail assembly provides protection and integration of the electronic components, thus simplifying installation and maintenance. Integrating the circuit board into the mounting rail assembly or functional module saves space and enables a compact design for the entire plumbing system.

[0021] According to a preferred embodiment, the receiving space is assigned to the mounting rail assembly, specifically to the receiving section. The receiving space serves as a dedicated area within the mounting rail assembly where the circuit board can be securely housed. This not only simplifies the installation and maintenance of the plumbing system but also improves its aesthetics by concealing cables and connections. A particular feature of this embodiment is the integration of at least one control interface into the wall and / or ceiling. This control interface can be designed as a smart home control interface, meaning that the plumbing system can be integrated into an existing smart home system. Using a smart home control interface enables interaction between the various components of the plumbing system and other smart home devices.This offers the advantage that the control and monitoring of the plumbing system can be centralized and automated. For example, the smart home control interface could be used to control the lighting, temperature, or other physical output variables of the plumbing system via a central smart home platform.

[0022] According to a preferred embodiment, the receiving space is assigned to the mounting rail assembly, and in particular to the receiving section. This mounting rail assembly includes at least one control interface, which is designed as a local control unit. This local control unit is located within the mounting rail assembly and connected to the circuit board via a control line. The mounting rail assembly thus serves not only for the mechanical fastening and stabilization of the functional modules, but also for the integration and guidance of electrical and control components. The local control unit within the mounting rail assembly enables decentralized control of the electrical loads, which increases the flexibility and adaptability of the sanitary installation.Connecting the control unit to the circuit board via the control cable ensures reliable and efficient communication between the various components. This arrangement offers the advantage of controlling the electrical components within the plumbing installation. An operator can therefore control the components from the shower area. Furthermore, integrating the control unit into the mounting rail provides a space-saving and aesthetically pleasing solution, as no additional external control devices are required.

[0023] According to a preferred embodiment, the mounting rail assembly comprises a connecting element configured to connect the receiving section to the connecting section. The receiving space is preferably integrated into the connecting element. The connecting section is preferably designed as a cross member that extends horizontally in the assembled state and is configured to connect the mounting rail assembly to a wall, with the connecting element acting as a corner connector. Alternatively, the connecting element is preferably designed as a ceiling connection that extends vertically in the assembled state and is configured to connect the mounting rail assembly to a ceiling, with the connecting element acting as a vertical connection. The connecting element enables a flexible and stable connection between the receiving section and the connecting section, which facilitates the installation and adjustment of the plumbing fixtures.Integrating the mounting space into the connector allows for slim dimensions of both the mounting and connection sections, as the mounting space for the circuit board is provided within the connector. This contributes to the system's compactness and efficiency by minimizing space requirements and simplifying plumbing installation. Designing the connection section as a crossbar or ceiling connection offers additional installation flexibility, as the mounting rail assembly can be attached horizontally to a wall or vertically to a ceiling. This enables versatile application of the plumbing installation in various spatial configurations and increases the system's adaptability to diverse structural requirements.The corner connector and the vertical connection, as specific designs of the connecting part, contribute to the stability and robustness of the connection, which improves the durability and reliability of the sanitary installation.

[0024] According to a preferred embodiment, the plumbing installation includes a fluid-tight secondary cable tray in which the first control line is routed. The fluid-tight nature of the secondary cable tray prevents water or other liquids from penetrating the cable tray and impairing the electrical connection or the function of the control line. This increases the safety and reliability of the entire plumbing installation by preventing short circuits or other electrical problems. Furthermore, the fluid-tight cable tray helps extend the service life of the electrical components by protecting them from corrosion and other moisture-related damage.

[0025] According to a preferred embodiment, the control interface of the mounting rail assembly comprises a first control interface, and the control line of the mounting rail assembly comprises a first control line. The first control interface and the first control line enable communication between the mounting rail assembly and the printed circuit board. The printed circuit board is connected via a second control line to a second control interface integrated into the wall or ceiling. This second control interface can, in particular, be a smart home control interface, thus enabling the integration of the plumbing installation into a smart home system. This configuration allows for improved control of the fixtures, which can be carried out either via the smart home control system or via the integrated control unit. User-friendliness is therefore further enhanced.

[0026] According to a preferred embodiment, the mounting rail assembly includes an operating interface associated with the control unit. The operating interface is preferably formed in a corresponding recess in an outer wall section of the mounting section facing the shower area. This operating interface allows direct user interaction with the control unit, thereby simplifying the operation of the various functional modules of the sanitary installation. Integrating the operating interface into the outer wall section of the mounting section offers the advantage of easily accessible and ergonomically positioned controls, thus increasing user-friendliness. Furthermore, arranging the operating interface in a corresponding recess creates an aesthetically pleasing and space-saving solution that does not detract from the overall appearance of the sanitary installation.The mounting rail arrangement, particularly the mounting section, not only provides a mechanical fastening option for the functional modules but also integrates the necessary control elements to ensure convenient and user-friendly operation. The corresponding recess in the outer wall section of the mounting section ensures that the operating interface is securely and stably mounted, thus guaranteeing long-term and reliable operation.

[0027] According to a preferred embodiment, the operating interface comprises a touchpad which, with a transparent disc, seals the recess in a fluid-tight manner. This arrangement enables intuitive and user-friendly operation of the sanitary installation, as a touchpad allows direct and simple interaction with the various functions of the sanitary installation. The use of a transparent disc for the fluid-tight seal of the recess offers the advantage that the control unit is protected from moisture and other environmental influences, which is particularly important in a humid environment such as a bathroom.

[0028] According to a preferred embodiment of the invention, at least one of the electrical loads is integrated into the functional module and connected to the inlet contact via the load connection. This configuration allows for seamless integration of the electrical load into the functional module, resulting in a more compact and aesthetically pleasing plumbing installation. The electrical load can be, for example, a lighting unit or a speaker system. Integrating the load into the functional module simplifies the plumbing installation, as fewer separate components need to be mounted and wired.

[0029] According to a preferred embodiment, at least one of the electrical components is designed as an electric heating element. An electric heating element can be used, for example, to regulate the temperature near the shower area, which is particularly advantageous in colder climates or during the winter months. Integrating the heating element directly into the shower enclosure offers a particularly efficient and space-saving heating option. Alternatively or additionally, at least one of the electrical components is designed as an LED light strip. An LED light strip provides an efficient and long-lasting lighting solution that can illuminate not only the shower area but also adjacent areas evenly. LEDs are known for their low energy consumption and long lifespan, which leads to a reduction in operating costs and maintenance.Alternatively or additionally, at least one of the electrical devices is designed as a speaker, radio, or tablet within a functional module or mounting rail assembly. This allows for an enhanced audio or visual experience while showering by integrating the speaker, radio, or tablet into the shower area. Alternatively or additionally, at least one of the electrical devices is designed as a hairdryer or drying device within a functional module or mounting rail assembly. This allows the user to be dried by an airflow within the shower area after showering. Alternatively or additionally, at least one of the electrical devices is designed as a wireless charging option on a room-facing side within a functional module or mounting rail assembly. This allows the user to conveniently charge their smartphone or other devices in the shower area.Alternatively or additionally, at least one of the electrical devices is designed as a clock or timer within a functional module or the mounting rail assembly. This allows the user to see the time while showering. Alternatively or additionally, at least one of the electrical devices is designed as an electric soap dispenser within a functional module or the mounting rail assembly. This allows the user to conveniently dispense soap and similar items from an integrated electric soap dispenser while showering. Alternatively or additionally, at least one of the electrical devices is designed as LED lighting for a wall-integrated storage compartment within a functional module. In this case, the functional module also serves as a piece of bathroom furniture. This contributes to increased user comfort and can also reduce the formation of condensation and mold in the shower area.The integration of LED lighting into a wall-integrated storage compartment within the functional module, which also serves as sanitary furniture, provides an additional light source that improves access to and visibility of items in the storage compartment. This eliminates the need for masonry work, which is typically required to create wall-integrated storage compartments, and simultaneously simplifies installation thanks to the integrated lighting. In the context of the invention, "wall-integrated" means that the storage compartment is recessed into the wall, extending from the wall surface into the wall and thus being flush with the wall.

[0030] The invention solves the aforementioned problem in a second aspect by means of a mounting rail arrangement according to claim 21. This mounting rail arrangement is designed such that, in a mounted state, it extends at least partially vertically along a longitudinal dimension and can be coupled to at least one functional module. The mounting rail arrangement comprises a connection section and a receiving section. The connection section of the mounting rail arrangement is configured to be connected to a distal room connection on the wall and / or ceiling side. The mounting rail arrangement further comprises a power cable guided in the connection section, which can be connected, at least indirectly, to an electrical load.The room connection includes a low-voltage connection that enables a conductive connection of the power cable to a power line installed in the wall or ceiling, which is designed to carry low-voltage current. By appropriately designing the mounting rail arrangement, the invention, according to the second aspect, incorporates the advantages mentioned at the outset with regard to the first aspect of the invention. Advantages and preferred embodiments according to the first aspect of the invention are also advantages and preferred embodiments according to the second aspect of the invention.

[0031] The invention solves the aforementioned problem in a third aspect by means of a functional module according to claim 22. The functional module forms, at least partially, a fluid-tight cavity enclosed by a module wall and contains a power cable housed within this cavity, which can be connected to an electrical contact of the retaining strip assembly via an electrical inlet contact in the module wall. This specific configuration enables a safe and efficient electrical connection by protecting and insulating the power cable within the cavity of the functional module. The fluid-tight cavity ensures that the power cable is protected from moisture and other environmental influences, which is particularly advantageous in a humid environment such as a shower.The electrical inlet contact in the module wall enables a simple and secure connection of the power cable to the mounting rail assembly, simplifying installation and maintenance. This arrangement optimizes the electrical supply to the functional modules, as the power cable is integrated directly into the module, eliminating the need for additional external cable connections. This reduces installation effort and time and minimizes the risk of electrical faults or short circuits. Furthermore, the fluid-tight design of the cavity provides additional protection against water ingress, increasing the durability and reliability of the electrical components.

[0032] According to a preferred embodiment, the functional module has two parallel longitudinal sides which, in the assembled state, run parallel to its longitudinal axis. A first longitudinal side can engage with a receiving section of a mounting rail assembly to form a sanitary installation, and the inlet contact is located on this first longitudinal side. This specific arrangement of the longitudinal sides and the inlet contact enables an optimized mechanical and electrical connection between the functional module and the mounting rail assembly. The parallel alignment of the longitudinal sides to the longitudinal axis ensures stable and secure mounting of the functional module, which facilitates installation and maintenance. This arrangement also contributes to an efficient and safe power supply to the functional module.
