Description

[0001] The invention relates to an assembly module according to the preamble of claim 1, as well as the use of an assembly module as an entry module for a residential unit and a water supply system for a residential unit.

[0002] The use of mounting modules for installing a washbasin is well known in the prior art. Such a mounting module typically comprises a module frame with vertical longitudinal struts and transverse struts. The module frame is usually made of metal. Such a module frame is typically designed to be robust enough to support a washbasin. Furthermore, the module frame is usually equipped with various fixing and holding devices, for example, threaded nuts and / or threaded bolts and / or retaining plates and / or other holding devices, so that a washbasin can be easily attached to the module frame and the water connections for the washbasin, typically a cold water connection and a hot water connection, as well as a drain pipe, can be easily attached to the module frame.For the proper installation of a washbasin, the mounting module is typically first positioned against a wall in a room and secured relative to the wall, for example, by fixing it directly to the wall itself and / or to the floor of the room. The washbasin is then attached to the module frame. The washbasin's cold water and hot water connections are usually fixed to brackets provided on the module frame and connected to cold and hot water pipes, respectively, that are already installed in the room. A washbasin faucet, which is attached to or enclosed by the washbasin, is then connected to these water connections. A drain pipe is also typically attached to another bracket provided on the module frame, and the washbasin's drain is then connected to this drain pipe. The drain pipe is connected to a drain line that is already installed in the room.

[0003] A mounting module of this type is designed as a cohesive assembly unit, meaning that the entire module, including all its components, can be moved as a single unit and thus positioned against a wall. Such mounting modules significantly simplify the installation of a washbasin, as the washbasin can be installed securely in a room without special preparations, and the brackets allow for easy connection of the washbasin to water pipes or a drain pipe. These mounting modules are frequently used in the construction of partition walls. In such cases, the mounting module is first positioned and secured in the room, after which the hot and cold water pipes are connected to the washbasin's cold water connection.The washbasin hot water connection is to be connected, and in particular, a drain pipe is to be attached to the module frame and connected to a drain line. A partition wall, such as a drywall, wood paneling, or similar, is then installed in front of the mounting module. The partition wall must have openings leading to the mounting module, providing access to the washbasin cold water connection, the washbasin hot water connection, and the drain pipe. Regardless of the challenges of installing a washbasin, there is also the issue that a hot and cold water line, as well as a drain line, must be installed in the room where a washbasin is to be installed.Typically, such pipes are laid along a room boundary, for example, along the ceiling, floor, and / or at least one wall of the room. These water pipes are equipped with outlets to which sanitary fixtures, such as a washbasin, toilet cistern, shower, or the like, can be installed. The usual approach is therefore to first lay such pipes in a room and then, to prepare for the installation of a washbasin, to install a mounting module, as described above, at the level of an outlet of the respective wall pipe. Furthermore, to facilitate the installation, removal, maintenance, or repair of a washbasin or other sanitary fixtures, a shut-off valve is usually provided on each of the hot and cold water pipes.This shut-off valve is usually installed once for each residential unit, allowing the hot or cold water supply to be interrupted or enabled for the entire unit. With the supply interrupted, a sanitary fixture can be installed or removed; with the supply enabled, the respective sanitary fixture can be used. Therefore, a complete water supply system for a residential unit requires some effort. Firstly, a central shut-off valve must be installed for the unit. Secondly, a water pipe must be laid from the shut-off valve within the unit, for example, to the bathroom and kitchen.Furthermore, in the case of a central hot water supply, a second shut-off valve must be provided to which the hot water line of the residential unit is connected. Alternatively, if the unit is to have its own cold water heater for hot water supply, a hot water heating system must be installed in the residential unit and connected on one side to the cold water line downstream of the first shut-off valve and on the other side to the hot water line of the residential unit. The numerous considerations that a plumber must take into account when designing a water supply system for a residential unit, and the many interconnected tasks that a plumber must perform, result in significant time and expense for the installation of plumbing systems in a residential unit.Especially in light of the high demand for living space and thus the high demand for the rapid completion of residential units and their sanitary installations or water supply systems, there is a desire for concepts that enable the fastest and simplest possible sanitary installation in a residential unit.

[0004] The present invention is based on the objective of providing an assembly module or a use of an assembly module or a water supply system with which at least one of the disadvantages or problems described above can be at least partially eliminated.

[0005] As a solution to the problem underlying the invention, the invention proposes an assembly module with the features according to claim 1. The assembly module is designed as a cohesive assembly unit. As explained with regard to generic assembly modules, the assembly module is thus not merely a set of components that can be arranged in any configuration relative to one another, but rather the assembly module is movable as a cohesive assembly unit, whereby the relative positions of the components of the assembly module are fixed during such movement. Thus, the assembly module can be moved to prepare for the installation of a washbasin against a wall and positioned in front of the wall. In general, an assembly module according to the invention, or its use, may have features that are described here in connection with assembly modules or uses known from the prior art.The mounting module comprises a module frame with vertically extending longitudinal struts and transversely extending cross struts. A fixing device for securing the washbasin, a first bracket for holding a washbasin cold water connection, and a second bracket for holding a washbasin hot water connection are arranged on the module frame. The brackets and the fixing device are fixed to the module frame, so that the mounting module is designed as a single, integrated assembly unit. Particularly preferably, the mounting module has a further bracket, also fixed to the module frame, designed to hold a drain pipe. The fixing device can, for example, comprise two mounting bolts, each with a nut that can be screwed onto it for securing a washbasin in a conventional manner. The fixing device can, for example, comprise a sheet metal plate.The brackets can be designed appropriately, for example by comprising a sheet metal plate with retaining eyelets and / or by being designed in a clamp-like manner.

[0006] According to the described solution according to the invention, a central cold water connection, a cold water distributor, and a cold water supply connection are fixed to the module frame, and the washbasin cold water connection is held on the first bracket. The central cold water connection, the cold water distributor, and the washbasin cold water connection are thus held on the module frame and are therefore part of the integrated assembly unit, which is how the assembly module is designed. The central cold water connection is designed for connection to a cold water line of a house and is connected, or connectable, to the cold water distributor in a fluid-carrying manner.The cold water distributor has a first outlet that is connected, or connectable, to the washbasin cold water connection, and a second outlet that is connected, or connectable, to the cold water supply connection, to which a cold water line from a residential unit can be connected. The cold water distributor is thus designed to be simultaneously connected, via its first outlet, to the washbasin cold water connection and, via its second outlet, to the cold water supply connection, while its inlet is connected, via its main inlet, to the central cold water connection, so that the washbasin cold water connection and the cold water supply connection are supplied with water via the cold water distributor.

[0007] The mounting module described above, according to the invention, enables a particularly simple implementation of a sanitary installation or a water supply system in a residential unit. Because the central cold water connection and the cold water distributor are integrated into the mounting module, which is designed as a single, cohesive unit, the module can be easily positioned at a location where a washbasin installation is already planned. A cold water line from the house can then be connected to the central cold water connection, and the cold water can be distributed directly via the cold water distributor included in the mounting module. The invention thus utilizes the unique concept of using a mounting module, originally intended for washbasin installation, simultaneously as a distribution module. This facilitates the implementation of a sanitary installation or a water supply system in a residential unit.The installation of a cold water line in a residential unit can be significantly simplified. A particularly advantageous feature is that the central cold water connection is fluid-carrying to the water distributor, and that the cold water distributor is fluid-carrying to both the washbasin cold water connection and the cold water supply connection. By installing such a mounting module, which already has a fluid-carrying connection as described, connecting the mounting module to the cold water line and distributing the cold water from the cold water line into the cold water line of the residential unit and to a washbasin faucet can be achieved very easily.The fluid-carrying connection can be advantageously realized, for example, by suitable pipes and / or by integrating the cold water distributor together with the washbasin cold water connection and / or the cold water supply connection into a single component. Due to the inventive design of the mounting module, the cold water supply connection and / or the central cold water connection can be specifically arranged at a height that is advantageous for connection to a cold water line. It is generally preferred that the cold water supply connection and / or the central cold water connection is spaced at least 60 cm vertically from the underside of the mounting module. It is generally preferred that the module frame has feet that can be fixed vertically in various positions relative to the longitudinal struts, so that the height of the mounting module can be adjusted by changing the vertical position of the feet relative to the longitudinal struts.The mounting module preferably has a height of more than 70 cm. In embodiments where the height of the mounting module is adjustable, for example by means of adjustable feet, the minimum adjustable height is preferably at least 70 cm. The mounting module preferably has a height of less than 130 cm. In embodiments where the height of the mounting module is adjustable, for example by means of adjustable feet, the maximum adjustable height is preferably at most 150 cm, and particularly at most 130 cm. The height is the vertical extension of the mounting module from its vertical underside to its vertical top, with feet preferably forming the vertical underside when provided.

[0008] In one embodiment, a shut-off valve is provided between the central cold water inlet and the outlets of the cold water distributor to prevent water flow from the central cold water inlet to the outlets of the cold water distributor. A fluid-carrying connection between the central cold water inlet and the outlets of the cold water distributor is thus only possible via the shut-off valve, so that in its closed position, the shut-off valve prevents water flow from the central cold water inlet to the outlets of the cold water distributor, and in its open position, it allows such water flow. The shut-off valve can, for example, be integrated into the cold water distributor or spaced apart from both the cold water distributor and the central cold water inlet and arranged between them.In one embodiment, a water meter is provided between the central cold water connection and the outlets of the cold water distributor to measure any quantity of water flowing from the cold water connection to the outlets of the cold water distributor. Thus, the water meter is preferably positioned in a fluid path between the central cold water connection and the outlets of the cold water distributor such that any quantity of water flowing from the central cold water connection to the outlets of the cold water distributor must flow through the water meter and is therefore recorded by the water meter. By providing a shut-off valve or a water meter, the function of the mounting module as a distributor module, which represents an inlet module for a residential unit and to which the cold water line of a house can be connected, and from which the water supply to the residential unit is provided, can be particularly enhanced. The shut-off valve or...The water meter can be integrated into the cold water distributor or provided separately. In a particularly advantageous embodiment, the mounting module comprises the shut-off valve and the water meter, wherein the shut-off valve and the water meter are fixed to the module frame by means of a retaining device. The retaining device can, for example, comprise a sheet metal plate or a board to which the shut-off valve and water meter are attached. The retaining device can, for example, include screw connections and / or clamps. The retaining device can be enclosed by the module frame or attached to it. Particularly preferably, the shut-off valve and the water meter are integrated into a water control module. The water control module is preferably a single, continuous component that is fixed to the module frame via the retaining device.The water control module can preferably be detached from the module frame as a single, integrated unit and replaced by an identical water control module. Integrating the shut-off valve and water meter into a single water control module can significantly simplify the manufacturing and integration of both components within the mounting module, as well as facilitate maintenance of the mounting module in the event of a faulty shut-off valve and / or water meter, or their replacement.

[0009] In one embodiment, lines, in particular pipes, are fixed to the module frame, connecting the central cold water connection to the cold water distributor in a fluid-carrying manner and / or connecting the cold water distributor to the washbasin cold water connection and / or to the cold water supply connection in a fluid-carrying manner. The lines are encompassed by the mounting module and fixed to the module frame. The central cold water connection is spaced apart from the cold water distributor and connected to it in a fluid-carrying manner by at least one of the lines. Alternatively or additionally, the cold water distributor is spaced apart from the washbasin cold water connection and / or the cold water supply connection and connected to it in a fluid-carrying manner by at least one of the lines. By spaced apart from the cold water distributor and / or by spaced apart from the washbasin cold water connection or the cold water supply connection, the central cold water connection is protected from the cold water supply connection.Since the cold water supply connection is spaced apart, these connections can be independently fixed to suitable positions on the module frame. Because the mounting module includes lines fixed to the module frame, which provide the described fluid flow, the entire mounting module can be easily set up and connected by an installer at the desired location. The fluid flow already integrated into the mounting module effectively prevents leaks or inadequate fluid flow caused by installation errors at the mounting location. Furthermore, this allows an installer to install the mounting module on-site in a room and connect it to the appropriate lines or connections in a particularly time-saving manner.To provide cold water to a residential unit, it is sufficient to connect the mounting module, installed in a room, with its central cold water connection to the cold water supply of the building, to connect a washbasin faucet to the washbasin cold water connection, and to connect the cold water line of the residential unit to the cold water supply connection. Preferably, the cold water supply connection is spaced apart from the washbasin cold water connection, the central cold water connection, and especially the cold water distributor, and is connected to the cold water distributor by one of the aforementioned lines.

[0010] In one embodiment, the cold water distributor is arranged transversely, particularly over a predominant part of its transverse extent, and especially over its entire transverse extent, between the central cold water connection and the second support. In another embodiment, the washbasin cold water connection is arranged transversely between the central cold water connection and the second support, and in yet another embodiment, the first support is arranged transversely between the central cold water connection and the second support. The central cold water connection can thus be provided in a transverse end region of the module frame, while the cold water distributor and the second support are provided on the same transverse side of the central cold water connection, the transverse end region preferably extending from a transverse end of the module frame over less than 30% of its total transverse extent.This allows the cold water connection to be particularly easy to access and the entire assembly module with its many components to be designed in a compact manner.

[0011] In one embodiment, the cold water distributor has an outlet distribution unit that forms the first and second outlets of the cold water distributor. The outlet distribution unit can be designed as a single, integrated component that can be reversibly disassembled and reassembled from the module frame. Preferably, the outlet distribution unit is held on the first support. Particularly preferably, the first outlet forms the washbasin cold water connection. By having the first outlet directly function as the washbasin cold water connection, a direct fluid-carrying connection between the first outlet and the washbasin cold water connection is thus ensured.In general, in one embodiment the cold water distributor can be designed as a single-piece unit, while in another embodiment it can comprise several distributor units, for example, an outlet distributor unit and at least one further distributor unit, such as the intermediate distributor unit described in more detail below. Each of the distributor units can be designed as a single, integral unit. Preferably, the distributor unit is designed in the form of an arc extending between two arc ends, one of which is configured as the inlet and the other as the outlet of the arc. Between its arc ends, the arc has a further outlet, which preferably forms the cold water connection for the washbasin. This further outlet can thus be the first outlet of the cold water distributor.The outlet formed at one end of the bend can, for example, serve as the cold water supply connection or be connected to, or connectable to, the cold water supply connection. The bend-shaped design of the distribution unit has proven to be particularly easy to manufacture and advantageous for use. By providing several distribution units connected to each other via pipes, with all distribution units and their connecting pipes being enclosed within the cold water distributor, the cold water distributor can be manufactured particularly easily. Furthermore, the distribution units can be positioned on the module frame at points where one of their outlets can directly serve as a connection, for example, as explained above, as a washbasin cold water connection, or, as explained in more detail below, as the third outlet of the cold water distributor.Preferably, the distribution units each have one inlet and at least two outlets, wherein one outlet of a first distribution unit is fluid-carrying connected to the inlet of a second distribution unit, and at least one of the outlets of the distribution units forms one of the outlets of the cold water distributor.

[0012] In one embodiment, the cold water distributor has a third outlet, which serves as a connection for a sanitary element that can be attached to the module frame. This sanitary element could be, for example, an instantaneous water heater or another sanitary component, such as a hygienic flushing device, a cistern, or the like. By having a third outlet, the cold water distributor allows the mounting module to be easily configured to supply multiple components with cold water fed into the central cold water connection from a cold water line of a building. More preferably, the cold water distributor includes an intermediate distribution unit with at least two outlets.A first outlet of the intermediate distribution unit forms the third outlet of the cold water distributor, and a second outlet of the intermediate distribution unit is configured to supply the washbasin cold water connection. Particularly preferably, the cold water distributor comprises an intermediate distribution unit and an outlet distribution unit as described above, wherein the second outlet of the intermediate distribution unit is configured to supply the outlet distribution unit, and the outlet distribution unit provides the washbasin cold water connection. Particularly preferably, an inlet of the intermediate distribution unit is connected to the central cold water connection, and an inlet of the outlet distribution unit is connected to one of the outlets of the intermediate distribution unit in a fluid-carrying manner, so that the outlet distribution unit can only be supplied with water from the central cold water connection via the intermediate distribution unit.

[0013] In one embodiment, the mounting module includes a washbasin hot water connection held on the second bracket. A hot water connection is fixed to the module frame, spaced apart from the second bracket, and is fluid-conducting or connectable to the washbasin hot water connection. A hot water supply for feeding the washbasin hot water connection can be connected to this hot water connection. With this embodiment, the invention takes a unique approach: While a mounting module typically only provides the water connections for a washbasin, this embodiment features both a hot water connection, to which a hot water supply can be connected, and the washbasin hot water connection itself, which is fluid-conducting or connectable to this hot water connection.Thus, regardless of the position of the washbasin hot water connection, a water supply can be connected to the hot water connection, and the aforementioned fluid-carrying connection enables the washbasin hot water connection to be supplied by the hot water supply via the hot water connection. Preferably, the washbasin hot water connection is spaced at least 30 cm, and in particular at least 40 cm, away from the hot water connection, so that the fluid-carrying line connecting them has a corresponding length of at least 30 cm, and in particular at least 40 cm.

[0014] In one embodiment, a cold water inlet and a hot water outlet connection for an instantaneous water heater are fixed to the module frame. The hot water outlet connection is designated as the hot water connection and is fluid-carrying, or connectable to, a hot water distributor fixed to the mounting module. In the described embodiment, an instantaneous water heater can thus be connected to both the cold water inlet and the hot water outlet connections, so that the instantaneous water heater is supplied with cold water from the cold water inlet connection and can supply the hot water distributor fixed to the module frame with hot water via the hot water outlet connection. Particularly preferably, the cold water distributor has the third outlet described above, with the instantaneous water heater being the sanitary element described above and the cold water inlet connection being the third outlet.Thus, in the particularly preferred embodiment, the cold water distributor feeds the instantaneous water heater via its third outlet, which functions as the cold water inlet, and the instantaneous water heater feeds the hot water distributor, which is enclosed by the mounting module, via its hot water outlet, which functions as the hot water inlet. This makes the functionality of the mounting module as a distribution module for a residential unit particularly advantageous.

[0015] Particularly preferably, the hot water distributor has a first outlet that is connected or connectable to the washbasin hot water connection, and a second outlet that is connected or connectable to a hot water supply connection to which a hot water line of a residential unit can be connected. In this particularly advantageous embodiment, the mounting module thus enables the supply of both the hot and cold water lines of a residential unit. This can be easily achieved by connecting the mounting module with its central cold water connection to a cold water line of the house and connecting the hot and cold water lines to the hot and cold water supply connections of the mounting module, respectively.It is generally preferred that the cold water supply connection and / or the hot water supply connection and / or the central cold water connection be spaced at least 60 cm away from the vertical underside of the mounting module.

[0016] The cold water distributor preferably includes an intermediate distribution unit as described above, wherein the mounting module has the described cold water inlet and hot water outlet connections, and the third outlet of the cold water distributor, formed by the intermediate distribution unit, serves as the cold water inlet for the instantaneous water heater. More preferably, the intermediate distribution unit of the cold water distributor is arranged vertically below the outlet distribution unit. The mounting module is more preferably placed on the floor of a room with its vertical underside. When the mounting module is installed in a room as intended, the vertical direction preferably points in the direction of the force of gravity acting on the ground.The intermediate distribution unit is generally preferably spaced vertically away from the outlet distribution unit, preferably by at least 5 cm, particularly preferably by at least 10 cm, and especially by at least 20 cm, wherein the intermediate distribution unit can be arranged, for example, below or above the outlet distribution unit. The assembly module, as described above, generally preferably includes a shut-off valve and a water meter, wherein the shut-off valve and the water meter are arranged vertically between the intermediate distribution unit and the outlet distribution unit.The inventors have determined that, due to this relative arrangement of the intermediate distribution unit and the output distribution unit, and in particular the shut-off valve and water meter, the mounting module can still be designed compactly despite the integration of a large number of components into the mounting module, and that a plumber can still easily connect the mounting module's connections to their intended connection partners, such as the hot and cold water connection of a washbasin tap, or the hot and cold water pipe, or the cold water inlet and hot water outlet of an instantaneous water heater.

[0017] Preferably, the mounting module has a transverse width of less than 70 cm, particularly less than 60 cm, and a width of at least 40 cm. Preferably, the washbasin hot water connection and the washbasin cold water connection are fixed to the module frame by means of first and second supports such that they have a defined distance from each other in the transverse direction, particularly a distance in the range of 12 cm to 17 cm, and more preferably a distance between their centers in the transverse direction of 15 cm. Preferably, the cold water inlet connection and the hot water outlet connection are fixed to the module frame in such a way that they have a defined distance from each other in the transverse direction, particularly in the range of 8 cm to 13 cm, and more preferably a distance between their centers in the transverse direction of 10 cm.It is generally preferred that the cold water inlet and hot water outlet connections are arranged at the same vertical height. It is generally preferred that the washbasin hot water connection and the washbasin cold water connection are arranged at the same vertical height. It is generally preferred that the cold water inlet and hot water outlet connections of the washbasin hot water connection and the washbasin cold water connection are spaced apart by at least 50 cm, in particular at least 60 cm, in particular at least 70 cm, and in particular by less than 90 cm, in particular less than 80 cm. It is generally preferred that the central cold water connection and the cold water supply connection and / or the hot water supply connection are arranged at the same vertical height, in particular within a vertical end region of the mounting module that forms the top of the mounting module and extends over less than 25% of the total vertical length of the mounting module.Preferably, the mounting module has a further support for holding a drain pipe, wherein the further support is arranged vertically below the washbasin hot water connection and washbasin cold water connection and above the cold water inlet and hot water outlet connection and / or above the water meter and / or shut-off valve.

[0018] As a further solution to the problem underlying the invention, the invention proposes an assembly module with the features according to claim 12. The assembly module of this solution according to the invention may, in advantageous embodiments, have features disclosed in connection with embodiments of the solution described above. Likewise, the solution according to the invention described above may, in advantageous embodiments, have features described in connection with embodiments of the solution explained in more detail below. The solutions according to the invention may be particularly advantageously combined. In particular, features described for a specific component of an embodiment of one of the two solutions may be provided for a corresponding or functionally equivalent component of an embodiment of the other solution.The mounting module according to this solution, as explained above, is designed as a cohesive mounting unit and is therefore movable and positionable in front of a wall to prepare for the installation of a washbasin. The module comprises a module frame with vertically extending longitudinal struts and transversely extending cross struts, on which a fixing device for fixing the washbasin, a first bracket for holding a washbasin cold water connection, and a second bracket for holding a washbasin hot water connection are arranged. According to the solution according to the invention described here, a cold water inlet and a hot water outlet connection for an instantaneous water heater are fixed to the module frame, and the washbasin hot water connection, which is located in front of the mounting module, is held on the second bracket.The hot water outlet is connected, or connectable, to a hot water distributor fixed to the module frame. The hot water distributor has a first outlet that is connected, or connectable, to the washbasin hot water connection, and a second outlet that is connected, or connectable, to a hot water supply connection fixed to the module frame, to which a hot water pipe from a residential unit can be connected. Preferably, the hot water distributor is designed as a single, continuous component, particularly a one-piece unit, especially in the form of an elbow as described above in relation to the distributor units.The mounting module, as described above, offers the distinct advantage that it incorporates inlet and outlet connections for an instantaneous water heater and a hot water supply connection, even though it is primarily intended for installing a washbasin. This allows not only the supply of hot and cold water to a washbasin and its faucet attached to the module's frame, but also, thanks to the integrated hot water distributor and supply connection, the hot water supply for an entire residential unit. The mounting module thus enables a particularly simple, quick, and cost-effective implementation of a hot water installation in a residential unit.Preferably, the mounting module has a central cold water connection designed for connection to a cold water supply line, wherein the cold water inlet connection is fluid-carrying to the central cold water connection, and the hot water outlet connection is fluid-carrying only via the hot water distributor to the washbasin hot water connection and to the hot water supply connection. Particularly preferably, the cold water inlet connection and the hot water outlet connection are located less than 50 cm, particularly less than 40 cm, particularly less than 30 cm, and particularly less than 20 cm from a vertical underside of the mounting module. Such connections are particularly advantageous for an electric instantaneous water heater. More generally, the mounting module preferably has an additional bracket for holding an electrical connection for an electric instantaneous water heater.The electrical connection is preferably spaced vertically less than 30 cm, and in particular less than 20 cm, from the cold water inlet and hot water outlet connections. Due to the design of the mounting module according to the invention, the hot water supply connection and / or the central cold water connection can be specifically arranged at a height that is particularly advantageous for connection to a hot water pipe or a cold water line. Generally, it is preferred that the hot water supply connection and / or the central cold water connection is spaced vertically at least 60 cm from the vertical underside of the mounting module.

[0019] In one embodiment, the mounting module includes a fixing device for securing the instantaneous water heater. Particularly preferably, the mounting module further includes a shut-off valve and / or a water meter as described above, and in particular a water control module as described above. The holding device for the shut-off valve and / or water meter and the fixing device are preferably fixed to at least one identical cross member of the module frame, and in particular fixed between two identical cross members of the module frame. This enables a particularly simple and robust fixing of the instantaneous water heater, shut-off valve, and / or water meter, since the same cross members can be used for robust fixing, and thus a specific group of cross members or a specific cross member can be designed to be sufficiently robust.Furthermore, this allows the numerous components of the mounting module to be fixed to the module frame in a particularly space-saving manner. The fixing device can, for example, comprise a plate, in particular a wooden or metal plate. In one embodiment, the cold water inlet and hot water outlet connections are fixed to the module frame in a predefined position relative to each other. In another embodiment, the cold water inlet and hot water outlet connections are fixed to the module frame in a predefined position relative to the fixing device.

[0020] In one embodiment, the cold water inlet and hot water outlet connections are both arranged on the same side, in the transverse direction, of the central cold water connection. Particularly preferably, they are arranged on the same side, in the transverse direction, of at least one of the washbasin cold water connection and washbasin hot water connection. More generally, at least one of the washbasin cold water connection and washbasin hot water connection is arranged transversely between the central cold water connection and the cold water inlet and hot water outlet connections. This allows the components to be fixed to the module frame in a particularly space-saving manner. More generally, the cold water inlet and hot water outlet connections are arranged transversely on the same side of the shut-off valve and water meter and spaced apart from them in the transverse direction.Preferably, the mounting module has an additional bracket for holding a drain pipe. Particularly preferred are the central cold water connection and at least one of the cold water inlet and hot water outlet connections arranged on two different sides, with respect to the transverse direction, of the additional bracket. Particularly preferred are the cold water distributor and / or the hot water distributor arranged at least partially vertically above the additional bracket and thus, when a drain pipe is properly fixed to the module frame via the additional bracket, positioned vertically above the drain pipe.

Preferably, in embodiments that have the central cold water connection, the hot water supply connection, and the cold water supply connection, these three connections are each spaced accordingly from the lower vertical end.

[0023] The invention further relates to the use of a mounting module according to the invention as an inlet module for a residential unit in a house. The residential unit preferably comprises a kitchen and a bathroom, with the mounting module preferably being used for installing and fixing a washbasin in the kitchen or bathroom. In the use according to the invention, a cold water line of the house is connected to the central cold water connection of the mounting module, with the entire water supply of the residential unit being provided exclusively via the mounting module through the cold water line. Thus, the mounting module functions as an inlet module through which the water is routed to supply the residential unit and then into the corresponding water lines of the residential unit.Preferably, a washbasin is mounted on the mounting module, particularly after connecting the cold water line and the cold water pipe and especially the hot water pipe to the corresponding connections of the mounting module and particularly after the construction of a pre-wall after said connection, wherein the washbasin fitting of the washbasin is connected to the washbasin cold water connection and to the washbasin hot water connection.In the invention, a flow heater, particularly an electric flow heater, is particularly preferred, being connected to the cold water inlet and hot water outlet connections, wherein the washbasin hot water connection and the hot water supply connection of the mounting module are supplied with hot water by the flow heater via the hot water outlet connection, wherein a hot water pipe of the residential unit is connected to the hot water supply connection, which runs from the room of the residential unit in which the mounting module is installed to another room of the residential unit in which a sanitary element is provided, for example another washbasin, a shower, a washing machine connection, a dishwasher connection or the like.In one embodiment, a cold water line from the residential unit is connected to the cold water supply connection of the mounting module. This line leads from the room in which the mounting module is installed into another room and supplies water to a sanitary element in this other room, such as another washbasin, a shower, a washing machine connection, a dishwasher connection, or the like.

[0024] The invention further relates to a water supply system for a residential unit. The water supply system comprises a hot water line and / or a cold water line, wherein the residential unit has at least two rooms, each with a hot water line outlet and a cold water line outlet for connecting a sanitary fixture, for example, a washbasin, a shower, a washing machine, a dishwasher, etc. The water supply system further comprises a mounting module according to the invention, which is connected to the cold water supply line of a house via its central cold water connection and which is connected to the cold water line via its cold water supply connection and / or to the hot water line via its hot water supply connection. Preferably, both the hot water line and the cold water line of the residential unit's water supply system are supplied with water.Particularly preferably, the assembly module has a shut-off valve, wherein the shut-off valve can have a release state and a closed state and only allows water to pass in the release state, wherein in the closed state of the shut-off valve the hot and cold water lines of the water supply system are separated from the cold water line and are therefore not supplied with water.

[0025] The invention is explained in more detail below with reference to two figures and exemplary embodiments.

[0026] They show: Fig. 1: in a schematic representation of principle an embodiment of an assembly module according to the invention; Fig. 2: in a schematic representation of principle an embodiment of a water supply system according to the invention for a residential unit.

[0027] In Fig. Figure 1 is a schematic representation of an embodiment of an assembly module 100 according to the invention. The assembly module 100 comprises a module frame 1, which has longitudinal struts 11 extending in the vertical direction Z and transverse struts 12 extending in the transverse direction Y. The lower vertical end of the assembly module 100 and the module frame 1 is formed by feet 15. These feet 15 are fixed in their position perpendicular to the vertical direction Z relative to the longitudinal struts 11, but can be fixed in different positions relative to the longitudinal struts 11 with respect to the vertical direction Z. Thus, the height of the assembly module 100 can be adjusted by changing the vertical position of the feet 15 relative to the longitudinal struts 11.

[0028] All other components of the assembly module 100, i.e., all components except the module frame 1 itself, are fixed to the module frame 1, which is generally advantageous according to the invention. By fixing all other components to the module frame 1, a cohesive assembly unit is created, allowing the entire assembly module 100 to be easily transported by an installer from the loading platform of a truck into a room of a residential unit, moved against a wall in that room, and positioned and fixed relative to it, for example, by screwing the feet 15 to the floor of the room and by screwing at least some of the longitudinal and / or transverse struts 11, 12 to the wall. This transportability and assembly capability of the entire assembly module 100 as a cohesive assembly unit is particularly advantageous according to the invention.After the mounting module 100 has been installed in the room, i.e., fixed relative to the wall of the room, a plumber can, thanks to the inventive design of the mounting module 100, connect the mounting module 100 particularly easily and quickly to a cold water line of the house in which the residential unit is located and to the water pipes laid in the residential unit independently of the mounting module 100 in order to realize a water supply system in the residential unit.

[0029] According to the in Fig. In the embodiment shown in Figure 1, the mounting module 100 comprises a washbasin cold water connection 73 and a washbasin hot water connection 83. The washbasin cold and hot water connections 73 and 83 are each fixed in position to the module frame 1 by means of a bracket. Furthermore, a drain pipe 6 is fixed to the module frame 1 by means of another bracket. The washbasin cold and hot water connections 73 and 83 and the drain pipe 6 are fixed in position to the module frame 1 such that they have a relative position to each other that a standard washbasin with standard fittings can be easily connected to them, i.e., with its washbasin faucet to the washbasin cold and hot water connections 73 and 83 and with its drain to the drain pipe 6.

[0030] The assembly module 100 described herein, according to the invention, further advantageously comprises a central cold water connection 2, which is provided at one end of a pipe of the assembly module 100. The pipe, and thus also the central cold water connection 2, is fixed to the module frame 1. The central cold water connection 2 is fluid-conducting connected via the described pipe to a water control module 5, which includes a shut-off valve 3 and a water meter 4. The water control module 5 is fixed in position between two crossbars 12 of the module frame 1 specifically provided for this purpose and is fluid-conductingly sealed to the central cold water connection 2, as well as fluid-conductingly sealed to a cold water distributor. The cold water distributor, according to the invention, advantageously comprises an intermediate distributor unit 72 and an outlet distributor unit 71.These distribution units 71, 72 are each designed in the form of a bend extending between two bend ends, one of which is configured as the inlet and the other as the outlet of the bend, with the bend having a further outlet between its bend ends. In the case of the intermediate distribution unit 72, the further outlet is configured as a cold water inlet connection 75 for an instantaneous water heater. The outlet formed at one of its bend ends is fluid-carrying connected to the inlet of the outlet distribution unit 71 via a further pipe. The further outlet of the outlet distribution unit 71 is configured as the washbasin cold water connection 73 described above.The outlet of the distribution unit 71, formed at one of its curved ends, is connected via a further pipe to the cold water supply connection 74, to which a cold water line of the described residential unit can be connected to supply the cold water line of the residential unit. With the described embodiment, which is generally advantageous according to the invention, connecting the central cold water connection 2 of the mounting module 100 ensures not only a supply to a washbasin via the washbasin cold water connection 73, but also a supply to the entire cold water line of the residential unit by connecting it to the cold water supply connection 74. Thus, the shut-off valve 3 of the mounting module 100 can function as a central shut-off valve for the entire cold water supply of the residential unit.Furthermore, when using an instantaneous water heater connected to the cold water inlet 75, as explained in more detail below, the mounting module 100 can also provide the hot water supply for the entire dwelling unit, so that the shut-off valve 3 of the mounting module 100 can function as a central shut-off valve for the entire water supply of the dwelling unit. Accordingly, the water meter 4 can measure any water consumption occurring in the dwelling unit.

[0031] In the described embodiment and generally advantageously according to the invention, the mounting module 100 further comprises a hot water outlet connection 82. The hot water outlet connection 82 and the cold water inlet connection 75 are both fixed to a sheet metal plate 16, which acts as a cross brace 12, and thus also fixed to each other. Their centers are arranged at the same vertical height, and their distance in the transverse direction Y corresponds to a standard distance provided for an electric instantaneous water heater. The hot water outlet connection 82 is connected via a further pipe to a hot water distributor 81, which, as described above for the distributor units 71, 72, is designed in the form of an elbow. One end of its elbow serves as an inlet, which is connected to the hot water outlet connection 82, in particular via a pipe, and carries fluid.The other end of the bend acts as an outlet, which is connected, in particular via a pipe, to a hot water supply connection 84 of the mounting module 100. Between its ends, the bend has a further outlet, which is designed as a washbasin hot water connection 83. The mounting module 100 also has a fixing device 14, which in this case is designed as a board and is fixed between two correspondingly designed crossbars 12 of the module frame 1. This fixing device 14 serves to fix a conventional instantaneous water heater to the module frame 1. Such an instantaneous water heater can thus be fixed in a position relative to the module frame 1 by means of the fixing device 14, while its inlet connection is connected to the cold water inlet connection 75 and its outlet connection to the hot water outlet connection 82.When installing such an electric instantaneous water heater, the mounting module 100 can be used particularly advantageously as a central distribution unit or as an inlet module for a residential unit by connecting its central cold water connection 2 to the cold water supply line of a house, its hot water supply connection 84 to a hot water line of the residential unit, and its cold water supply connection 74 to a cold water line of the residential unit. As shown in the diagram. Fig. As can be seen in Figure 1, the central cold water connection 2, the cold water supply connection 74, and the hot water supply connection 84 are all spaced sufficiently far from the vertical underside, i.e., the lower vertical end, of the mounting module 100 to be easily accessible for an installer. Furthermore, the mounting module 100 is suitable as a standard washbasin mounting module. For this purpose, a fixing device 13, comprising a mounting bolt, is provided for fixing the washbasin relative to the module frame 1, and the connections of the washbasin fitting and its drain can be connected to the washbasin hot and cold water connections 73 and 83, as well as the drain pipe 6, which are fixed to the module frame 1.

[0032] In Fig. Figure 2 shows a highly simplified schematic representation of an embodiment of a water supply system for a residential unit according to the invention. Such a water supply system according to the invention can be implemented, for example, by using a mounting module 100 according to the invention as an inlet module for a residential unit in a house. A cold water pipe 700 and a hot water pipe 800 are provided in the residential unit, running through several rooms of the unit, which is generally advantageous according to the invention. For example, one of these rooms can be configured as a bathroom, another as a kitchen, and, in particular, another as a guest toilet. Each of the rooms has an outlet from each of the water pipes 700 and 800.For example, a kitchen sink 200 can be provided in one room, and a shower 300 in another, each connected to a branch of the respective water pipe 700, 800. In the described embodiment of the water supply system according to the invention, or in its use according to the invention, an embodiment of a mounting module 100 according to the invention is employed. For example, this could be a mounting module 100 as shown in... Fig. Figure 1 illustrates the functionality of the assembly module 100. Fig.Figure 2 is a highly simplified schematic representation. The mounting module 100 has a central cold water connection 2, via which it is connected to a cold water line of a house in which the residential unit is located. The central cold water connection 2 is connected to a water control module 5 of the mounting module 100, which includes at least one shut-off valve 3, in particular a shut-off valve 3 and a water meter 4. A cold water distributor 7 is located downstream of this water control module 5. A first outlet of the cold water distributor 7 is connected, with fluid flow, to a washbasin cold water connection 73 of the mounting module 100. A second outlet of the cold water distributor 7 is connected, with fluid flow, to the cold water supply connection 74, to which the cold water line 700 of the residential unit is connected.A third outlet of the cold water distributor 7 is connected, with fluid flow, to a cold water supply connection to which an instantaneous water heater 9 is connected, in this case an electric instantaneous water heater. Such an instantaneous water heater 9 has a cold water inlet through which it receives cold water, and a hot water outlet through which it supplies hot water. The hot water outlet of the instantaneous water heater 9 is connected to a hot water outlet connection of the mounting module 100, which is connected, with fluid flow, to a hot water distributor 8 of the mounting module 100. The hot water distributor 8 has a first outlet, which is connected, with fluid flow, to the washbasin hot water connection 83, and a second outlet, which is connected, with fluid flow, to the hot water supply connection 84 of the mounting module 100, to which the hot water pipe 800 of the residential unit is connected.It should be noted that, in this context, the term "fluid-carrying" preferably means "sealing fluid-carrying," ensuring leak-free fluid flow between the fluid-carrying connected elements. The water supply system according to the invention thus utilizes the feature of the embodiment of the assembly module 100 according to the invention, namely that the cold water distributor 7 has an inlet that is fed from the cold water line via the central cold water connection 2, and outlets with which it supplies the instantaneous water heater 9, the cold water supply connection 74, and the washbasin cold water connection 73, whereas the instantaneous water heater 9, with its hot water outlet, supplies an inlet of the hot water distributor 8, which in turn supplies the washbasin hot water connection 83 and the hot water supply connection 84 with its outlets.Thus, the shut-off valve 3 of the water control module 5 can be used to enable or disable the water supply for the entire residential unit, depending on the state of the shut-off valve 3. Since the mounting module 100 is designed as a cohesive mounting unit, it is not only a washbasin module and therefore not only used for mounting a washbasin, but also functions as a distribution module that can be connected to the central cold water supply of a house and handles the distribution of water into the water pipes of the residential unit.
