Description

[0001]Ma / pj December 18, 2024 Applicant: TECE GmbH 48282 Emsdetten WC mounting module with leakage protection The invention relates to a mounting module for a WC according to the preamble of claim 1 and a WC arrangement comprising a WC and such a mounting module as well as a set for implementing such a mounting module and a use of such a mounting module. Generic mounting modules can be installed in a wall as a flush-mounted module and comprise a flushing device for discharging flush water vertically downwards and, as connecting pipes, a flush pipe for supplying the flush water from the flushing device to the WC and a drain pipe for discharging waste water from the WC. As the mounting module is designed as a flush-mounted module, i.e. can be installed in a wall, the mounting module does not interfere with a room, but is concealed from view for a user standing in the room, for example by a wall paneling provided on a front side of the mounting module, for exampleTiles, or the mounting module itself can have a decorative plate or cover plate, which forms a front side of the mounting module and which can be adjacent to a wall cladding of the room on its sides. Such a mounting module further has a supply connection, which comprises at least one water connection for supplying the flushing device and can also have an electrical connection for providing a supply to electrical components of a toilet connected to the mounting module. Usually, the water connection is connected to a pressurized water supply line. The flushing device can be actuated by an actuating device from a front side of the mounting module, for which various solutions are known in the prior art. A valve of the flushing device can be actuated by such an actuating device, and by actuating this valve, the flushing water can be discharged from the flushing water outlet of theThe flushing device is thus discharged and fed to the toilet via this. The valve of the flushing device is thus arranged between the supply connection of the flushing device, which is formed by the water connection of the mounting module or connected to it, and the flushing water outlet of the flushing device, and depending on the position of the valve, a flow of flushing water flowing through the supply connection into the flushing device out of the flushing water outlet is enabled or prevented. Generally preferably, the flushing water outlet is configured as an opening enclosed by an edge, wherein the valve has a valve element which, in the closed state, rests against the edge in a circumferentially sealed manner around the opening and is spaced from the edge in the open state. The vertical position of the flushing water outlet is formed by the vertically lowest position of the end of the section of the edge which surrounds the opening and points towards the opening, at whichthe valve element forms a sealing seal when closed. In most cases, the flushing device comprises a cistern designed to store water for flushing the toilet and, for this purpose, has a cistern wall defining an interior of the cistern. Furthermore, such a flushing device comprises a fill valve connected to the water connection of the supply line and arranged in the cistern, as well as a drain valve connected to a flush water outlet of the cistern and arranged in the cistern. Fill valves and drain valves are absolutely common in the prior art. The drain valve is actuated via an actuating plate, from which at least one actuating pin of the actuating device extends to the drain valve. The flush pipe is formed in one piece with the cistern or is at least partially manufactured as a separate component and connected to it. The flush pipe canbe formed in one piece or in several parts. Frequently, a first flush pipe section is formed in one piece with the cistern, wherein at least one further flush pipe section is connected to this first flush pipe section, in particular is detachably connected, wherein in particular the further flush pipe section or one of the further flush pipe sections is formed as a flush pipe bend. The flush water outlet of the flushing device is usually formed by an opening in the bottom of the cistern, to which a valve seat of the drain valve is fixed, which in a closed state prevents the flush water stored in the cistern from escaping through the flush water outlet and in an open state is spaced from the opening, so that the flush water stored in the cistern can escape from the flush water outlet stored in the cistern. Furthermore, flushing devices designed as pressure flushers are also known, which with their access to the water connection of thesupply connection and which have a valve that can be operated with an actuating device. With such a pressure flusher, the water connection is connected to a pressurized water supply line, and when the flushing device is actuated by means of the actuating device, the flushing device allows the water flowing under pressure from the water supply line to flow from its flush water outlet as flush water directly via the flush pipe into the toilet. In any case of generic mounting modules, the problem exists that a water flow must be guaranteed at the mounting module, and therefore a leakage can occur. Since, when the mounting module is used as intended, the mounting module and thus also a potential leakage point are integrated into the wall, such a leak is often only noticed late, possibly even too late. Especially when using a mounting module in buildings that areare predominantly constructed of wood, such as in Scandinavian countries, such an undetected leak can have very significant and serious consequences (rotting, decay, mold growth, etc.). Approaches to providing an assembly module that takes this problem into account are already known in the prior art. For example, it is known in the prior art to provide a connection for the water supply connection that is suitable for a water supply line that is designed in a "pipe-in-pipe" construction, i.e., which comprises an inner pipe for supplying tap water to the cistern and an outer pipe, with the inner pipe being arranged within the outer pipe. The "pipe-in-pipe" construction of the water supply line is particularly advantageous for buildings made of wood and is even required in some countries, such as Norway. It offers protection in the event of a leak in the inner pipe, since water that accidentally escapes from the inner pipe can beThe outer pipe can be collected and drained away. The outer pipe thus serves as a protective pipe for the inner pipe, in which the water is regularly conveyed under pressure, and prevents water from escaping into the building structure and thus causing water damage. While the outer pipe is also suitable for fluid conveyance, it is normally dry if there is no leak. The inner pipe is preferably a plastic pipe, particularly a pipe made of cross-linked polyethylene (PEX pipe). If the inner pipe ruptures, the water enters the outer pipe. The outer pipe directs the leaked water into a drain or visibly onto the floor of a room. The outer pipe is often designed as a corrugated pipe. The publication "Ror-i-ror-systemer," published by the Norwegian Building Research Institute in 2006 (ISBN 82-536-0925-6), provides a detailed description of the "pipe-in-pipe system." The pipe-in-pipe design can counteract this.be that a leak in the water-carrying pipe of the water supply line remains undetected and leads to permanent dampness in a wall. Such a water connection is often designed in such a way that a leak in the water-carrying inner pipe is led through the outer pipe via the water connection to the flushing device, in particular into the cistern. However, such a water connection adapted to a pipe-in-pipe design does not guarantee any precautionary measure with regard to leaks occurring outside the water supply line, for example a leak at a valve of the flushing device or at the inlet or outlet of the cistern or at the cistern wall. Furthermore, it is known, for example, from EP 3138968 B1 to provide a protective sheath outside a cistern, which has a hose-like extension on its underside, through which leakage water can be released into a room in front of a wall paneling, so that the leakcan be noticed. However, with this solution, the implementation and installation of such a protective cover is complex, and the protective cover can only be adapted with difficulty to all possible requirements arising during the installation of a toilet. The present invention is based on the object of providing a mounting module for a toilet or a toilet arrangement or a set for implementing a mounting module or a use of a mounting module, with which damage to a building due to an undetected leak in components of the mounting module can be prevented as far as possible and with which at least one disadvantage that exists in generic mounting modules or toilet arrangements or uses can be at least partially remedied. As a solution to the object underlying the present invention, the invention proposes a mounting module with the features according to claim 1. The mounting module is designed such thata toilet can be connected to the mounting module. The connection preferably comprises both a mechanical installation, i.e. fixing the toilet to a wall via the mounting module, and the fluid-conducting connection of the flush water and waste water connection of the toilet via the flush pipe and drain pipe of the mounting module to the building-side water supply line or waste water line, after the mounting module has been set up in a room and fixed to a building wall and connected to the building-side lines. Preferably, the mounting module can be used as a flush-mounted module and thus, when used as intended, can be installed in a wall or integrated into a wall. In general, a wall can comprise a building wall, wherein a pre-wall enclosed by the wall is provided at a distance from the building wall in front of the building wall, on the front of which a wall paneling is arranged and which delimits a room with its front side, wherein the mounting modulea proper use, at least with the majority of its extension, in particular completely, is arranged within the area lying between the building wall and the front of the partition wall. The mounting module comprises a flushing device for discharging flushing water vertically downwards. When the mounting module is used as intended, the vertical direction is the direction in which the weight acts on the earth. The mounting module further comprises a supply connection and, as connecting pipes, which are connected to the toilet when the toilet is connected to the mounting module, a flush pipe for supplying the flushing water from the flushing device to the toilet and a drain pipe for discharging wastewater from the toilet. The flush pipe preferably has a flush pipe socket at its end intended for connection to the toilet. The drain pipe preferably has a drain pipe socket at its end intended for connection to the toilet.Flush pipe sockets and drain pipe sockets are well known in the art; in most cases, flush pipe sockets and drain pipe sockets are designed according to standards to correspond with the standardized corresponding connections of the toilet. To connect the toilet to the mounting module, a drain connection pipe of adjustable length and a flush connection pipe of adjustable length are usually used, with which the connection between the drain pipe socket and the corresponding drain connection of the toilet and between the flush pipe socket and the corresponding flush connection of the toilet is established, whereby the length of the respective connection pipe is adjusted to the existing distance between the toilet and the respective socket. The drain pipe of the mounting module is preferably designed to be connected to the toilet at one end and to a building-side sewage pipe at its other end. The mounting module hasFurthermore, a protective cover surrounding the flushing device for collecting leakage water. The protective cover surrounds the flushing device in such a way that dripping leakage water occurring at least at the flushing device is collected by the protective cover before it can reach the wall into which the mounting module is intended to be integrated. Preferably, the protective cover is arranged at least on the rear and on the underside, particularly preferably at least on the rear and on both transverse sides of the flushing device and on the underside of the flushing device. Preferably, the protective cover surrounds the flushing device at its underside. Generally, the mounting module is bounded in a first spatial direction (sagittal direction) by a front and a rear side, in a second spatial direction (transverse direction) by two transverse sides, i.e., the left and right sides, and in a third direction (vertical direction) by the top and bottom.wherein the three spatial directions are perpendicular to one another. In one embodiment, the protective cover is open at its front side, wherein it has an opening at its front side, wherein the opening extends in particular over at least 30%, in particular at least 50% of its extension length in the transverse and vertical directions. The opening is thus preferably designed as an inspection opening. Preferably, the opening has an extension in the transverse direction of at least 30 cm, in particular at least 40 cm. Preferably, the opening has an extension length in the vertical direction of at least 20 cm, in particular at least 30 cm, in particular at least 40 cm. Components of the assembly module, in particular at least components of the flushing device, in particular at least the entire flushing device, and / or at least components of a water distributor, in particular at least the entire water distributor, in particularbe advantageously accessible. The protective sheath preferably encloses the flushing device at least in two spatial directions on both sides and in particular furthermore in the third spatial direction on at least one side, in particular in all three spatial directions on both sides. The protective sheath preferably encloses the flushing device at least in the transverse direction and sagittal direction over at least one vertical section on both sides and at least on its underside. At least preferably, the arrangement of the protective sheath around the flushing device by means of the protective sheath ensures a collecting device which collects leakage water dripping from the flushing device in a trough-like manner, in particular also collects any leakage water dripping from the supply line connection. The protective sheath has a discharge opening for discharging collected leakage water. The protective sheath is preferably designed to discharge the leakage water collected by it exclusively via the discharge openingto dispense. Preferably, the dispensing opening is provided at a lower end and / or at a front side of the protective cover. According to one embodiment, the dispensing opening is fluid-conductingly connected to one of the connecting pipes or is connected to a fluid line that can be fluid-conductingly connected to one of the connecting pipes. For example, the dispensing opening can be fluid-conductingly connected directly to the flush pipe or the drain pipe as one of the connecting pipes via a fluid line, or the dispensing opening can be connected to a fluid line that has a connection at its end facing away from the dispensing opening that corresponds to a connection that can be connected, for example, to the flush pipe or the drain pipe, for example directly or indirectly, in particular by means of a toilet. The connection of the fluid line to be connected can, for example, be designed as a screw connection or plug connection, as is known in the prior art.is generally known and customary, in particular according to a common standard for a water connection, so that the connection of the fluid line to be connected can be sealingly and in particular detachably connected to the corresponding connection. When providing a fluid line that is connected to the dispensing opening, its end facing away from the dispensing opening has a sufficient fit or rigidity to be connected to a corresponding connection so that the fluid can be guided from the dispensing opening via the fluid line and subsequently to one of the connecting pipes. Generally preferably, the dispensing opening is connected to the flush pipe as a connecting pipe in a fluid-conducting manner. This can particularly advantageously ensure that leakage water can be drained from the dispensing opening into a toilet by means of the flush pipe and then discharged from the toilet via the drain pipe into a building-side drain pipe.Fluid-carrying connection or connectability of the outlet opening with one of the connecting pipes allows leakage water to be led directly, in particular by means of the properly connected toilet, into a building's wastewater line without reaching the floor of a room and collecting there, and without penetrating the building structure and damaging it. In one embodiment, the mounting module has an empty pipe that opens into an interior of the protective cover and / or runs at least partially within the interior. The empty pipe has an empty pipe end, from which a line can be inserted into the empty pipe. The empty pipe end is accessible from a front side of the mounting module, so that a line can be inserted from the front side of the mounting module into the empty pipe end and thus from the empty pipe end into the empty pipe. The empty pipe end can be designed as an open end with a clear cross-section that extends into the front side of theassembly module, wherein the clear cross section of the empty conduit end preferably lies in a plane spanned by the explained transverse and vertical directions. Preferably, the empty conduit is designed and arranged relative to the protective sheath such that its clear cross section is arranged within a cross section of the dispensing opening or that it extends offset from the dispensing opening from an interior of the protective sheath to the outside. With an offset arrangement of the clear cross section of the empty conduit relative to the clear cross section of the dispensing opening, it can be provided that these clear cross sections are separated from one another by a partition wall, wherein the partition wall is preferably formed by the protective sheath. The empty conduit has a clear cross section that is delimited by an empty conduit wall of the empty conduit. In one embodiment, the empty conduit wall forms the said partition wall. With an arrangement of the clear cross section of the empty conduitWithin the opening cross-section of the dispensing opening, the opening cross-section of the dispensing opening is larger than the clear cross-section of the empty pipe so that leakage water can escape from the dispensing opening alongside the clear cross-section of the empty pipe. Particularly preferably, the opening cross-section of the dispensing opening is at least 1.5 times, in particular at least 2 times, the clear cross-section of the empty pipe. In any case, the provision of the empty pipe offers the particular advantage that at least one, in particular exactly one, line, in particular a water line and / or electrical line, can be led through the empty pipe into the interior of the protective sheath, so that such a line can be connected to a corresponding connection, in particular a connection of the supply line connection, and can be led out of the protective sheath from this connection. The provision of the empty pipe offers the particular advantage thata corresponding line can be subsequently introduced into the empty conduit and thus subsequently laid over the empty conduit so that it runs inside the protective sheath. Accordingly, one end of the empty conduit is arranged so that it is accessible from the outside, i.e. from outside the interior of the protective sheath, so that a line can be laid from the outside through the empty conduit. In one embodiment, the supply connection has a water connection, which is sealingly connected to an outer side of the protective sheath. This has the particular advantage that the water connection is directly connected to the protective sheath in a water-conducting manner, so that leakage water escaping at the water connection can be directly collected by the protective sheath. The advantageously provided empty conduit preferably runs to the water connection. The water connection is preferably pre-assembled on the outer side of the protective sheath and is thereby sealingly connected to theOutside of the protective cover. Preferably, the water connection is designed to be connected to a corresponding connection of the flushing device, in particular to be connected to the flushing device within the interior of the protective cover delimited by the protective cover. In one embodiment, the protective cover has an actuating opening through which an actuating device provided for triggering the flushing device can be inserted into the protective cover from the outside, wherein the protective cover preferably also has an installation channel enclosing the actuating opening. Preferably, the installation channel is designed to conduct fluid. At least part of the interior of the protective cover is accessible through the actuating opening so that an actuating device can be connected to the flushing device arranged at least partially in the interior of the protective cover. The installation channel forms a casing around the section of theActuating device, with which the actuating device extends from the outside into the protective cover, so that the installation duct can fulfil a sealing function by being attached to or connected to one side of the wall with its end facing away from the interior of the protective cover, so that the actuating opening can be provided without there being a risk of leakage water penetrating between the front of the wall and the protective cover. In one embodiment, the mounting module has a mounting element, wherein the mounting module has fixing devices which are fixed to the mounting element and which, while fixing the protective cover, cooperate with holding devices of the protective cover which are formed by an outer side of the protective cover. By the fixing devices provided on the mounting element interacting with holding devices which are formed by the outer side of the protective cover and thus notare arranged on the inside of the protective cover, with which the protective cover delimits the interior space enclosed by it, it can be particularly advantageously ensured that the interaction of fixing devices and holding devices does not cause any leakage of the protective cover. Preferably, one of the holding devices is assigned to one of the fixing devices, wherein the pair of holding device and assigned fixing device cooperate to fix the holding device by means of the fixing device relative to the mounting element and thus to fix the protective cover relative to the mounting element. The holding devices can, for example, be formed by a simple outer side section of a bag-like protective cover or by a flange-like section of the protective cover. Generally, the holding device and assigned fixing device are preferably connectable to one another in a detachable, fixable manner, in particular without tools.detachably connectable to one another, so that the protective cover can be particularly easily detached from the mounting element by releasing the holding devices from the associated fixing devices. Alternatively or additionally, the fixing devices can be designed to be detachably connectable to the mounting element. In one embodiment, the mounting module, in addition to the flushing device, has a water distributor with a central connection and several branch lines branching off from the central connection, wherein the water distributor is arranged within the protective cover. By arranging the water distributor within the protective cover, the protective cover can also collect leakage water escaping from the water distributor and discharge it through the discharge opening. The water distributor has at least one central connection and several branch lines branching off from the one central connection. In embodiments, the water distributor can also have several central connections, of whichseveral branch lines each branch off, assigned to the respective central connection. Of course, the branch lines encompassed by the water distributor do not necessarily have to end in the protective sheath, but can continue outside the protective sheath with further branch line sections, and accordingly, the central connection can be provided on a water pipe that extends from the outside into the protective sheath. It is essential that the central connection and branch lines branching off from it are arranged in the water distributor so that any leakage water occurring there can be collected by the protective sheath. Preferably, at least one, in particular at least the majority, of the branch lines, in particular all branch lines, each have a connection by means of which they can be connected to a line section of a water pipe. By arranging the branch lines with their connections in the protective sheath,all leakage water occurring at the connections of the branch lines is collected by the protective sheath. The assembly module according to the invention, with its respective embodiments, brings with it considerable advantages compared to the prior art. The various solutions according to the invention and the various embodiments of the solutions can be combined with one another in a particularly advantageous manner and can each advantageously have features that are explained here in connection with generic assembly modules. This applies both to the various described embodiments of an assembly module and to the various described embodiments of a toilet arrangement, a set and a use of an assembly module, all of which can each have features that are disclosed in connection with other embodiments or can be combined with other embodiments, including other solutions according to the invention.The solutions or embodiments according to the invention ensure that the protective cover provides sufficient sealing to prevent leakage water from entering the building structure when the mounting module is used as intended, in which the mounting module is installed in a wall of the building, with a toilet arranged at the front of the mounting module and connected to the flush pipe and drain pipe of the mounting module, and the flushing device connected to a water supply line of the building via the supply line connection and actuated by an actuating device. The various embodiments according to the invention are always dedicated to the problem of realizing a functional mounting module that is sealed against leakage water in a practical manner that is as simple as possible for an installer during installation of the mounting module to enable its intended use.Installation of a mounting module, which is to be carried out by an installer, comprises the arrangement of the mounting module in the wall and the fastening of the mounting module relative to the wall as well as the connection of the supply connection of the mounting module to a building-side water supply line and in particular to a building-side electrical supply line, the fastening of the toilet, in particular to the mounting module, in particular by means of conventional fastening screw bolts as a wall-mounted toilet spaced from a room floor, and the connection of the flush pipe and drain pipe to the toilet and the setting up of the actuating device such that the flushing device can be actuated to perform a flush. In one embodiment, the outlet opening is fluid-conductingly connected to the flush pipe by a fluid guide. The fluid guide is enclosed by the mounting module. Through the fluid-conducting connection, water emerging from the outlet opening is directed by means of the flush pipe into theWC. The flush pipe extends from the flushing device, in particular from the flush outlet of the flushing device, with its flush pipe extension, along which it conducts flush water from the flushing device to the connected WC when used as intended, to its end pointing away from the flushing device. With its end pointing away from the flushing device, the flush pipe can thus be connected to the corresponding flush connection of a WC by means of a flush connection pipe. The end of the flush pipe, which is connected to a corresponding connection of a WC when the assembly module is used as intended to create a WC arrangement, is arranged behind the outlet opening in the flow direction of the flush water emerging from the outlet opening. While the protective sheath guides the leakage water to the outlet opening, the flush pipe guides theLeakage water into the toilet. Particularly preferably, the fluid guide opens into the flush pipe at a connection point. In an advantageous embodiment, the connection point is arranged above a lower end of a clear cross-section of the flush pipe, which the flush pipe has at its end facing away from the flushing device, preferably arranged vertically spaced from this lower end of the end of the flush pipe facing away from the flushing device above this lower end, in particular by at least 0.5 cm, in particular by at least 1 cm, in particular by at least 2 cm. The lower end of the clear cross-section of the flush pipe at its end facing away from the flushing device defines a specific vertical position, which is determined by the clear cross-section of the flush pipe at its said end. In an advantageous embodiment, the connection point is from a lower end, i.e. absolute lowerend of the flush pipe, in particular by at least 1 cm, in particular by at least 2 cm, in particular by at least 3 cm vertically, with reference to the absolute lower end of the flush pipe. Particularly preferably, the connection point is spaced from both an upper end and a lower end of the flush pipe by at least 10%, in particular at least 15%, in particular at least 20% of the vertical height of the flush pipe, i.e. the entire vertical extent of the flush pipe. The flush pipe usually forms its lower end at its end to be connected to the toilet, which end is usually formed by a flush pipe socket of the flush pipe. The upper end of the flush pipe is usually connected to the flush water outlet of the flushing device, so that the flush water flowing out of the flushing device when it is actuated reaches the upper end of the flush pipe. By the connection point at which the outlet opening is connected via theFluid guide opens into the flush pipe, is arranged vertically above the lower end of the clear cross section of the flush pipe, which the flush pipe has at its end facing away from the flushing device, leakage water emerging from the outlet opening can be particularly advantageously diverted through the flush pipe into a toilet connected to the flush pipe. The connection point is arranged with its vertically lower end above, in particular vertically spaced above, the lower end of the clear cross section of the flush pipe, which the flush pipe has at its end facing away from the flushing device. Preferably, the flush pipe is designed to be connected with this end by means of a flush connection pipe to a corresponding flush connection of a toilet. By the connection point being separated both from the flush water outlet and from the absolute lower end of the flush pipe, in particular as explained from the lower end of its clear cross section, which itat its end facing away from the flushing device, both a reliable drainage of all potentially occurring leakage water into the flush pipe and a drainage of the leakage water through the flush pipe into a toilet connected to it can be advantageously ensured. In one embodiment, the mounting module comprises a backflow preventer for preventing flush water from the flush pipe from entering the protective sheath through the outlet opening. The backflow preventer can, for example, be designed as a check valve. Generally preferably, the backflow preventer is designed in such a way that it allows leakage water from the outlet opening into the flush pipe at any time, but prevents flush water from the flush pipe from flowing into the protective sheath through the outlet opening. For example, the backflow preventer can be designed as a check valve that is attached to the outlet openingand / or at the connection point and / or in the fluid guide and which is pressed against a sealing seat when flushing water flows from the flushing pipe towards the interior of the protective cover, whereas when leakage water flows from the discharge opening into the flushing pipe, it is automatically released from the sealing seat by the flow of the leakage water. In one embodiment, the discharge opening opens into an opening of the flushing pipe, in particular via the fluid guide, wherein the opening of the flushing pipe is enclosed by a section of the flushing pipe. Said section thus defines the opening cross-section of the opening. The protective cover is preferably arranged in a sealing manner against this section of the flushing pipe. This creates a sealing seal between the protective cover and the section of the flushing pipe surrounding the opening, thus preventing fluid from escaping, so that all leakage water thatextending from the discharge opening to the opening of the flush pipe, entering the flush pipe through the opening of the flush pipe and being unable to run uncontrolled along the outside of the flush pipe. In one embodiment, the flush pipe has a pipe wall that encloses a clear cross-section of the flush pipe. The flush pipe is designed to guide flushing water within its clear cross-section. In one embodiment, a wall section spaced apart from the pipe wall and the protective sheath is arranged within the clear cross-section, wherein the discharge opening opens into the flush pipe between the pipe wall and the wall section. The wall section can thus help to prevent flushing water from the flush pipe from entering the protective sheath through the discharge opening. The wall section can thus, for example, act as a baffle plate or protective plate to prevent flushing water, in particular flushing water splashes, from entering the protective sheath.by means of the discharge opening. The wall section can be formed, for example, by a backflow preventer. The wall section can be formed, for example, at least partially by a check valve running within the clear cross-section of the flushing pipe and / or at least partially by a pipe section of the flushing pipe running within the clear cross-section of the flushing pipe. The pipe section can be designed to guide flushing water from the flushing water outlet of the flushing device past the opening of the flushing pipe into which the discharge opening of the protective sheath opens. Preferably, the flushing pipe has a pipe section located within its clear cross-section, which is connected to the flushing water outlet of the flushing device, so that, starting from the flushing water outlet, the flushing water emerging from it is initially fixed in its course to the clear cross-section of the pipe section of the flushing pipe, wherein thePipe section is arranged within the clear cross-section of an outer pipe of the flushing pipe, which forms the said pipe wall of the flushing pipe, in particular is spaced from the pipe wall of the flushing pipe, in particular is spaced from the pipe wall of the flushing pipe over at least the predominant part of its extension, wherein the extension is based on its pipe axis. Preferably, the flushing pipe has a check valve of the backflow preventer, which is spaced between the pipe section and the pipe wall and allows a vertical water flow from top to bottom between the pipe section and the pipe wall and prevents a vertical water flow from bottom to top between the pipe section and the pipe wall. In one embodiment, the flushing pipe has a flushing line and a branch connected to the flushing line, wherein the flushing line is connected to a flushing water outlet of the flushing device and theDischarge opening is connected to the branch for discharging water via the branch into the flushing line. By providing such a branch, the entry of flushing water from the flushing line, which is connected to the flushing water outlet, into the discharge opening can be prevented in a particularly simple manner, if possible. The flushing line preferably forms the flushing pipe socket of the flushing pipe, with which the flushing pipe is to be connected to a flushing water inlet, i.e. flushing water connection, of a toilet when used as intended to create a toilet arrangement. The branch preferably opens vertically below the discharge opening into the flushing line. The flushing water outlet is preferably arranged vertically above the point at which the branch enters the flushing line, the flushing water outlet, and the point at which the branch opens into the flushing line. This also allows for the flushing water outlet or the connection point betweenLeakage water escaping from the flushing water outlet and flushing line is guided via the discharge opening and by means of the branch into the flushing line. In one embodiment, the flushing pipe is connected with a connection end to a flushing water outlet of the flushing device, wherein the discharge opening is arranged vertically below the connection end. Preferably, the discharge opening is arranged at a distance from the vertically lower end of the flushing pipe by at least 10%, in particular at least 20%, of a vertical extension length of the flushing pipe, which the flushing pipe has from its vertically lower end, i.e. absolute lower end, to the flushing water outlet and thus to its connection end connected to the flushing water outlet. Furthermore, the discharge opening is particularly preferably arranged at a distance from the flushing water outlet by at least 5%, in particular at least 10%, in particular at least 15%, in particular at least 20% of this vertical extension length of the flushing pipe.arranged at a distance below the flushing water outlet. Generally preferably, the protective sheath is made at least partially, in particular completely, from a softer material than the flushing pipe. Generally preferably, the protective sheath has a sheath thickness that is less than the pipe wall thickness of the flushing pipe, in particular at most 70%, in particular at most 50%, in particular at most 30%, in particular at most 20% of the pipe wall thickness of the flushing pipe. In one embodiment, the mounting module has a signaling device that is arranged at a location in the protective sheath and is designed to output a signal upon detection of water at the location. Particularly preferably, the location in the interior of the protective sheath is arranged relative to the discharge opening in such a way that leakage water collected in the protective sheath must pass this location in order to reach the discharge opening. In one embodiment, the signaling device is designed to output aelectrical signal upon detection of water at the location. For this purpose, detectors well known in the art can be used, which can be used in such a signaling device provided for outputting an electrical signal. For example, such a detector can be designed as an optical detector that detects the presence of water at the location by a change in the optical properties of this location, for example a photodiode-based detector, or the detector can be designed to detect changes in the shape of a material that changes its shape in the presence of water, for example by swelling. Such a change in shape can, for example, also be detectable by an optical detector or by a strain gauge. In one embodiment, the signaling device is designed to output a signal in a change in the shape and / or color of a front side of the mounting module.existing signal when water is detected at the location. For example, an element can be provided on the front of the module which is connected to the location in a water-conducting manner, for example by means of a capillary, and which changes its color or shape upon contact with water so that this can be easily perceived by a user standing in a room in whose wall the mounting module is integrated. For example, a color change can consist of a dye being provided at the location which colors the leaking water before it is dispensed at the outlet opening so that the colored leaking water is visible at the front of the mounting module, for example at the front of the flush pipe, and thus acts as a signal itself. In one embodiment, the signaling device has a signal converting device which converts the electrical signal into a signal that is particularly easy for a user to perceive.For example, the signal conversion can consist in generating a warning tone or showing a warning message on a display on the front of the mounting module.

The running of the empty pipe to the supply line connection ensures that the line can be guided to the supply line connection by means of the empty pipe. The empty pipe can end with its end facing the supply line connection directly at the supply line connection or can point at a distance from the supply line connection. The latter case can have the particular advantage that leakage water that occurs at the connection point between the line and the supply line connection can be easily collected outside the empty pipe by the protective sheath and discharged via the outlet opening.

The empty conduit wall can be designed as a completely closed and thus uninterrupted continuous empty conduit wall over the entire length of the empty conduit or can have recesses along the length of the pipe, which, however, where possible, ensure sufficient guidanceof the line in the empty conduit. In one embodiment, the empty conduit is designed as a coherent, one-piece component.

Thus, such an armored hose can preferably be inserted into the empty conduit from that end and, while being pushed into the empty conduit from this end of the empty conduit, can be guided through the empty conduit through the guide provided by the empty conduit until one end is arranged at the supply line connection. A armored hose with a standard size of DN8 or DN10, provided in accordance with the standard valid at the time of filing, or if applicable, the priority date of the present application, is known to a person skilled in the art within the scope of their professional expertise as an absolutely common line that has sufficient robustness and rigidity to ensure reliable water flow.

Generally, the empty pipe is preferably integrated into the protective cover at least in such a way that it is integrally connected to the protective cover. By integrating the empty pipe into the protective cover, the empty pipe can be realized particularly easily and, moreover, a reliable seal at the transition between the protective cover and the empty pipe can be ensured.In one embodiment, the mounting module has a mounting element to which the flush pipe is fastened by means of a fastening device. The fastening device particularly preferably comprises a clamp. The fastening device rests with a fastening section on the flush pipe so that it can ensure the fastening of the flush pipe relative to the mounting element. In one embodiment, the fastening device has vertical passages offset from the fastening section, which are designed to allow the leakage water to pass vertically from an upper side of the fastening device through the passages to an underside of the fastening device, so that the vertical passages can lead to the fastening device preventing the drainage of leakage water within the protective cover towards the dispensing opening as far as possible. Generally preferably, the fastening device has a fastening component whichvertical passages. Generally preferably, the fastening device comprises a clamp and the fastening component, wherein the fastening component is pressed against the flush pipe by the clamp to fix the flush pipe. The fastening component can, for example, be designed in the manner of a ring, in particular in the manner of a slotted ring, so that the ring can be radially compressed and thus can be mounted pressing against the flush pipe. Generally preferably, the fastening component can be designed in the manner of a fan ring, which has horizontal struts and vertical passages between the struts, wherein the fan ring can be designed as a slotted ring, as explained.

In one embodiment, the empty pipe is fixed in its position by the fastening device, i.e. by the same fastening device that fixes the flushing pipe relative to the mounting element. Preferably, the fastening device has a fastening component that simultaneously serves to fix the position of the empty pipe and to fix the flushing pipe relative to the mounting element. The fastening component can be designed in the manner of a ring with vertical passages, for example in the manner of a fan ring.

It should be noted that the flush pipe can of course be assigned a radius and thus also a radial direction. The tangential direction runs perpendicular to the radial direction. By having the empty pipe radially spaced from the fastening section or arranged tangentially between two sections of the fastening section, compression of the empty pipe, i.e. a reduction of its clear cross-section, can be effectively prevented and at the same time a reliable fixation of the flush pipe relative to the mounting element and a sufficiently robust and simple fixation of the empty pipe relative to the mounting element can be ensured. In one embodiment, the supply connection of the mounting module has a water connection or is designed as a water connection. The water connection has aOuter element for connection to an outer pipe of a water supply line and an inner element for connection to an inner pipe of the water supply line. Preferably, the outer element is sealingly connected to the protective cover, in particular sealed relative to an outer side of the protective cover, so that when the outer pipe of the water supply line is connected to the outer element, leakage water that reaches the protective cover from the outer pipe can only be drained by the outer element to the interior of the protective cover and thus cannot get between the outer element and the outer side of the protective cover. The water supply line is thus preferably designed according to a pipe-in-pipe construction, so that it has an inner pipe and an outer pipe surrounding the inner pipe. The inner pipe is suitable for conducting water and thus for connection to a water supply pipe under water pressure. The outer pipe is designed toIn the preferred embodiment, the water connection further comprises an inner element to which the inner pipe of the water supply line can be connected.

Particularly preferably, the inner pipe can be reversibly connected to the inner element and detached from the inner element, while the outer element remains unchanged and sealed against the protective sheath, in particular remains unchanged and pressed against the protective sheath. By pressing the outer element from the outside onto the protective sheath,In a particularly advantageous manner, a sealing connection between the outer element and the protective cover can be ensured, so that when the outer pipe is connected to the outer element and a leak occurs on the inner pipe, leaked water from the inner pipe can be guided through the outer pipe to the outer element and from there can reach the protective cover without leakage and can be discharged from there via the discharge opening. In one embodiment, a valve of the flushing device can be reversibly connected to and detachable from the inner element, while the outer element remains sealed against the protective cover, in particular remains pressed against the protective cover without change. The reversible connectability or detachability of the inner pipe to the inner element or of the valve on the inner element can be particularly advantageous for the revisability of the assembly module. In general, the outer element preferably presses theProtective cover against a cistern of the flushing device. The cistern can form a sufficiently robust abutment for the pressing force to be exerted, and by pressing the protective cover against the cistern by means of the outer element, a sealing connection between the outer element and the protective cover and a sealing connection between the protective cover and the cistern, and thus a sealing connection between the outer element and the cistern, can be ensured. In one embodiment, the inner element is fixed in a fixed position to the protective cover and / or to a cistern surrounded by the protective cover in an operating state of the assembly module in which it is used as intended to implement a toilet arrangement. This can particularly preferably be a reversibly detachable fixation. Generally, the valve of the flushing device is fixed in a fixed position to the protective cover and / or to the cistern by means of the inner element in the operating state.fixed. This ensures a reliable arrangement of the inner element and protective cover or of the valve and protective cover relative to one another. In one embodiment, the outer element and / or the inner element of the water connection is pre-assembled to the protective cover. In the pre-assembled state of the outer element on the protective cover, the outer pipe of the water supply line can be connected to the outer element, while the outer element remains unchanged in the pre-assembled state and thus remains connected to the protective cover. Accordingly, in one embodiment, it is provided that the inner element is fastened in a pre-assembled state relative to the protective cover and in this pre-assembled state, the inner pipe can be connected to the inner element. In one embodiment, the flushing device has a cistern, wherein the outer element is connected to the protective cover at a distance from the cistern in a fluid-conducting manner to the interior of the protective cover.is attached so that water escaping from the outer pipe enters the protective cover outside the cistern when the water supply line is connected to the water connection. Naturally, the outer element is sealingly connected to the protective cover. This embodiment can particularly advantageously ensure that leakage water conducted from the outer pipe to the mounting module is guided into the interior of the protective cover as simply as possible and can then be discharged from the outlet opening of the protective cover. The mounting module comprising a water connection that is at least partially pre-assembled as explained can be used particularly advantageously by an installer for installation, wherein the mounting module with pre-assembled outer element and / or inner element can be fixed as a complete unit to a wall of a room and then the water supply pipe with outer and inner pipes can be connected to the water connection.In one embodiment, the water connection has a shut-off valve. The shut-off valve can prevent a water supply and thus prevent the continuation of a leak occurring in the protective cover. The shut-off valve is particularly preferably connected to the signaling device explained above, wherein upon detection of water at the location, which can be carried out as explained above, the shut-off valve can be controlled to close by means of the signaling device, so that no water can reach components located in the protective cover through the water connection. In one embodiment, the installation duct has a flange which runs continuously around the actuating opening and projects laterally beyond a duct wall of the installation duct. The flange is preferably provided at a front end of the installation duct. The flange preferably forms a section of a front side of the installation duct. TheInstallation channel with its front side facing away from the flushing device. The channel wall can be formed in one piece or in several parts, i.e. consisting of several separate parts. In general, in one embodiment, the installation channel is formed in one piece with a shell body of the protective cover, with which the protective cover surrounds the flushing device. In general, in one embodiment, the protective cover can have at least two shell parts. For example, a first shell part can form the shell part of the protective cover with which it surrounds the flushing device, wherein the first shell part preferably has the discharge opening. In one embodiment, the installation channel is formed by a second shell part. For example, the first shell part can be sealingly connected to a lower section of the flushing device and the second shell part can be sealingly connected to an upper section of the flushing device. The protective cover can also have more thanhave two casing parts, for example, a further casing part that surrounds a water distributor as explained in more detail here. The numbering of the casing parts is not to be understood as limiting, but merely serves to assign the respective casing part to the properties indicated with the same numbering in the respective context. In one embodiment, the flushing device has a cistern, wherein the protective casing has a first casing part that surrounds the cistern in order to collect leakage water escaping from the cistern, wherein this first casing part has the discharge opening of the protective casing, wherein the protective casing has a second casing part that encloses the installation channel and is connected to the cistern in a sealing manner around an inspection opening of the cistern. This can ensure that splash water entering the installation channel from a room can becannot penetrate the wall, but with a sealing integration of the flange of the installation channel in a sealing plane of the wall, the spray water can only be guided within the installation channel, i.e. within the channel wall up to the cistern and there can enter the cistern via its inspection opening, but cannot penetrate into the wall. In one embodiment, the installation channel is designed in several parts, wherein a first part of the installation channel is formed integrally with a shell body of the protective cover, with which the protective cover surrounds the flushing device and which forms the discharge opening of the protective cover, wherein the installation channel has at least one further part that is connectable to the first part, in particular detachably connectable. For example, the channel wall of the installation channel can be designed in several parts, for example, the channel wall can be telescopicbe formed and comprise an outer pipe and an inner pipe, which are movable relative to one another in a sealing manner while adjusting the duct length. For example, the flange of the installation duct can be formed by at least one component manufactured separately from the duct wall. For example, the flange of the installation duct can be formed by a sealing sleeve as explained in more detail below or by a sealing strip attached to the duct wall all the way around the duct wall. The flange is particularly advantageous for sealing integration into a wall cladding surrounding the installation duct. The actuating opening fundamentally represents a potential leak in the protective cover. However, since the actuating opening is enclosed by the installation duct, i.e. by the duct wall of the installation duct, and furthermore the flange protrudes laterally beyond the duct wall, the flange can be sealingly connected to a front side of theWall cladding and, on the other hand, the duct wall provides a water guide so that no water can penetrate into the actuation opening, which could then penetrate uncontrolled into the building structure, since the actuation opening is connected to the interior of the protective cover by means of the installation duct and, moreover, the flange ensures the sealing connection of the installation duct to adjacent wall sections. The flange is preferably designed in a suitable manner so that a seal can be ensured between the duct wall and the wall sections adjacent to the installation duct by means of the flange. In one embodiment, the duct wall and flange are integrated into a one-piece component. In one embodiment, the flange is formed by at least one component manufactured separately from the duct wall, which seals against the duct wall to create the assembly module.For example, the flange can be formed by a multi-part sealing sleeve that can be connected to the duct wall, in particular plugged transversely onto the duct wall, or a sealing sleeve that can be pushed onto the duct wall, or by an adhesive sealing tape that can be glued onto the duct wall. For example, the flange can be formed by shell parts that can be arranged around the outside circumference of the duct wall and, to create the assembly module, can be sealingly connected to one another and to the duct wall. It has proven particularly advantageous to provide a coating on the front and / or rear side of the flange. The coating can, for example, be designed as an adhesive coating and / or as a fabric coating or nonwoven coating. Such a coating can be particularly advantageous for connecting a sealing element, for example an adhesive sealing tape or a sealing paint. A nonwoven or fabric coating can be used for adhesion of aSealing coating can be particularly advantageous. Although the coating makes the production of the assembly module more complicated overall, it has been recognized that the coating offers significant advantages, in particular a simpler sealing integration of the protective cover into a sealing layer of the wall by bonding the sealing layer to the coating provided on the front and / or back of the flange. Generally speaking, the channel wall is therefore preferably made of a different material than the coating. Preferably, the channel wall and a base structure of the flange, which already protrudes laterally beyond the channel wall, are made of the same material, in particular plastic, with the coating being provided on this base structure. Particularly preferably, the channel wall is made of a smooth plastic, whereas the coating is, in comparison, rougher and / or stickier and / or more absorbent.In one embodiment, the installation duct extends with its duct extension direction over a duct length from its rear end to its front end. The duct extension direction indicates the direction along which the installation duct runs with its clear cross-section. The cross-section is thus perpendicular to the duct extension direction. Particularly preferably, the flange is provided at the front end of the installation duct. With its rear end, the installation duct preferably merges into an adjacent section of the protective sheath. An actuating pin of the actuating device can be guided through the installation duct. Preferably, the duct length of the installation duct is adjustable between a minimum length and a maximum length. The adjustability can be ensured by a suitable design of the duct wall. Preferably, for each adjustable duct length of the duct wall, the flange is sealingly connected to theThe flange is connected to the duct wall. This ensures that, for each adjustable duct length, the flange protrudes laterally beyond the duct wall of the installation duct, so that the flange can be used to seal the duct wall to a wall section of a wall cladding surrounding the duct wall or the installation duct. Preferably, for each adjustable duct length of the duct wall, the flange forms a section of the front of the installation duct. For example, to create an assembly module in which the duct length of the duct wall is adjustable and the flange is sealingly connected to the duct wall for each set duct length, the duct wall can be made of a material whose length can be adjusted along the duct extension direction, or made of a separable material, so that the duct length can be adjusted starting from the maximum length by cutting off a duct wall section.is, starting from the maximum length, the length of the channel wall is shortened in the direction of channel extension by the length of the severed channel wall section. For example, the channel wall can be designed to be elastic, i.e. stretchable, and / or in the manner of a bellows and / or telescopic and / or made of a severable material. In a telescopic design, the channel wall can be designed in several parts, wherein the several parts together form the telescopic design and are thus displaceable relative to one another in the direction of channel extension. For example, the channel wall can be made of a cuttable material or have webs arranged one behind the other in the direction of channel extension, which each run around the clear cross-section and on each of which a tear-off tab is provided, via which they can be severed from one another to shorten the channel length. In one embodiment, the flange has several in theThe installation duct has partial flanges spaced apart from one another in the direction of duct extension, wherein, to adjust the duct length, the duct wall can be severed between each two partial flanges adjacent in the direction of duct extension, so that for each set duct length, one of the partial flanges always forms at least part of the front of the installation duct. In one embodiment, the flange is designed to be movable relative to the duct wall along the direction of duct extension. For this purpose, the flange can be connected, for example, to a flexible film that is connected to the duct wall, for example, at the rear end of the duct wall, wherein the flexible film preferably surrounds the duct wall like a sleeve to ensure mobility of the flange along the direction of duct extension relative to the duct wall. In one embodiment, the flange is formed by a sealing sleeve that can be sealingly connected to the duct wall. The sealing sleeve is characterized bygenerally characterized in that it has a planar extension within which an opening is provided, wherein the planar extension encloses the opening in a closed manner. The channel wall is arranged in the opening. The sealing sleeve can be designed in one piece or in several parts. The sealing sleeve can, for example, be plugged laterally, i.e. transversely and / or vertically onto the channel wall and thus consist of several parts that are connected to one another by plugging them in. The sealing sleeve can, for example, be designed in the form of a film or plate and be connected to the channel wall by means of an adhesive sealing tape. The connection between the sealing sleeve and the channel wall is provided in one embodiment on an outer side of the channel wall, in one embodiment on an inner side of the channel wall, in a further embodiment both on the outer side and on the inner side of the channel wall. Preferably, theSealing sleeve for implementing the assembly module can be applied to the duct wall, wherein in one embodiment the duct wall is to be cut to its desired length before applying the sealing sleeve and sealingly connecting the sealing sleeve to the duct wall, and in one embodiment the duct wall can also be cut to length after applying the sealing sleeve to the duct wall and sealing the sealing sleeve relative to the duct wall. Generally preferably the sealing sleeve is designed such that it can be pushed onto the duct wall in a sealing manner, in particular pushed onto the duct wall from a front side of the duct wall along the duct extension direction. Generally preferably the sealing sleeve has a first region with which it rests against the duct wall, and a second region which encloses the first region and with which it projects laterally beyond the duct wall. In this case the sealing sleeve projects with the secondArea preferably extends circumferentially around the channel wall laterally over the channel wall, i.e. preferably both in the transverse and vertical directions. In one embodiment, the sealing sleeve has an opening which is enclosed by the first area and in which the channel wall can be arranged or is arranged. Preferably, the channel wall can be inserted into the opening when the sealing sleeve is pushed on. Preferably, the opening has a greater extension length in a first direction than in a second direction, wherein the first and second directions are perpendicular to one another. Preferably, the first direction corresponds to the transverse direction and the second direction to the vertical direction. Preferably, the extension length in the first direction is at least 1.2 times, in particular at least 1.3 times, preferably at least 1.5 times the extension length in the second direction. Preferably, the extension length of the opening in the first direction isat least 15 cm and in the second direction at least 7 cm, in particular at least 10 cm. Generally, the channel wall preferably has a greater extension length in a first direction than in a second direction, in particular at least 1.2 times, in particular at least 1.3 times, in particular at least 1.5 times the extension length in the second direction. Preferably, the extension length of the channel wall in the first direction is at least 15 cm and in the second direction at least 7 cm, in particular at least 10 cm. Preferably, the first and second directions are perpendicular to one another, in particular the first direction runs in the transverse direction and the second direction in the vertical direction. The sealing sleeve is thus designed to be connected to the channel wall, which has a considerable extension length in the first and second directions, so that the channel wall can enclose a considerable clear cross-section. Thus, a sufficientSize to enable the passage of actuating pins of an actuating device must be ensured. The sealing sleeve is thus preferably specifically adapted to be sealingly connected to the channel wall, wherein the channel wall and in particular the opening of the sealing sleeve have correspondingly large dimensions and in particular correspondingly unequal dimensions in the first and second directions. Generally preferably, the sealing sleeve has a planar extension which is spanned by the vertical and transverse directions, wherein the sealing sleeve extends beyond the channel wall by more than 1 cm, in particular more than 2 cm on each side perpendicular to the sagittal direction, and in each area which is arranged outside the channel wall, ie in the area in which the sealing sleeve extends laterally beyond the channel wall and which is spaced from the channel wall by more than 5 mm, an extension length in the sagittal direction ofless than 3 mm, in particular less than 2 mm. This makes it particularly easy to integrate the sealing sleeve into a sealing plane of a wall with its area extending laterally beyond the duct wall. In general, it should be noted at this point that the sealing between the duct wall and the wall section surrounding the duct wall is particularly demanding, as this area is usually perceived particularly closely and, upon completion of the installation of the assembly module, tiles are usually provided in this area. Due to the above-mentioned extension of the sealing sleeve, a seal between the duct wall and the surrounding wall section can be ensured in a particularly simple and elegant manner. In one embodiment, the sealing sleeve is designed to be elastically deformable in its first area and / or the duct wall is designed to be elastically deformable and / or the sealing sleeve is glued to the duct wall.An elastic design of the first region of the sealing sleeve and / or the channel wall can ensure a particularly reliable, easy-to-implement seal between the channel wall and the sealing sleeve. Bonding can enable a particularly cost-effective implementation of the sealing sleeve. In one embodiment, the sealing sleeve is made of a stiffer material, at least in sections of the first region, than in other sections of the sealing sleeve. This has the particular advantage that the sealing sleeve can thereby have sufficient robustness to ensure a reliable seal relative to the channel wall. For example, the first region can be made of a stiffer material in sections where sections of an elastic material are provided, which bear sealingly against the channel wall. In one embodiment, the sections made of a stiffermaterial, over a larger proportion of the extension length of the opening in the first direction than in the second direction. This makes it possible to take into account the special circumstances that arise when the opening extends over a greater extension length in the first direction than in the second direction, since the stiffer sections can particularly advantageously ensure sufficient stiffness of the sealing sleeve even with a correspondingly large extension length in the first direction, via which a sufficient sealing of the sealing sleeve relative to the duct wall can be achieved. In one embodiment, the flange is at least partially formed by a sealing element arranged on the duct wall. The sealing element can, for example, form part of the sealing sleeve or establish a sealing connection between the sealing sleeve and the duct wall. In one embodiment, the sealing element is designed asExpansion element formed. For example, the sealing element can be designed as an expansion strip which, in a pre-assembled state, is covered by a cover strip, wherein by loosening the cover strip, an expansion of the expansion element can be generated, so that the sealing element can seal the duct wall on its outer side to a laterally adjacent element, for example a laterally adjacent wall section or a laterally adjacent sealing sleeve. The sealing element can, for example, be designed as a sealing ring, an elastic sealing lip or an expansion element. Generally preferably, the flange is designed in the manner of a closed ring which has a front end running in one plane and / or a rear end running in one plane.

For example,The flange and / or the intermediate body can be made of a fiber-reinforced plastic. By providing a different, in particular stiffer, material for producing the flange and / or the intermediate body, waviness of the flange can be particularly advantageously avoided, so that the flange particularly advantageously has a front end running in one plane and / or a rear end running in one plane, whereas such waviness is often difficult to prevent when the flange is made of the same material as the duct wall, for example when providing conventional joining techniques for the flange and duct wall, such as welding.

Such a dimensionally stable plastic box, unlike a bag-like cover, has a defined geometric shape, which it always maintains when it is placed on a base without an external force acting on it. The design of the protective cover as a dimensionally stable plastic box can enable particularly simple mounting of the protective cover on a mounting element and / or in a recess in a wall and / or a particularly simple arrangement of the flushing device in the protective cover. The plastic box is preferably designed as a watertight collecting tray, wherein leakage water can be discharged vertically below the plastic box through the discharge opening.The plastic box has a removable lid on its front side, which ensures the above-explained separability of the protective cover on its front side.

In one embodiment, a first partial shell forms a lower section of the protective cover and is connected to a second partial shell forming an upper section of the protective cover, wherein the first partial shell is designed as a collecting tray for collecting leakage water and the discharge opening is arranged on the first partial shell. As a result, the flushing device can be inserted particularly easily into the first partial shell designed as an open collecting tray, wherein thesecond partial shell, the escape of leakage water spraying out laterally into a wall can be effectively prevented and a simple placement of the second partial shell onto the first partial shell can be made possible, wherein the first partial shell and the second partial shell are preferably designed to correspond to one another in such a way that, in the intended operating state, in which the plastic box is formed by means of the partial shells, the second partial shell is arranged overlapping with the first partial shell such that the second partial shell diverts spray water collected by it into the first partial shell. In one embodiment, the protective cover has at least one of the holding devices on at least two opposite sides, each of which is fixed by means of one of the fixing devices to a mounting element, in particular indirectly via a cistern of the mounting module fastened to the mounting element. The opposite sidesare two sides which, with respect to a specific spatial direction, form a different end of the protective cover. The holding devices can be designed, for example, in the manner of an eyelet, a hook, a flange section, or by means of another designed outer side section of the protective cover. The fixing devices are designed to correspond to the holding devices, for example, in the manner of a hook, an eyelet, or a retaining clip. The holding devices are preferably arranged on an outer side of a protective cover wall of the protective cover and extend away from the protective cover wall, wherein the protective cover wall delimits, with its inner side, the interior of the protective cover in which the rinsing device is arranged. The holding devices are thus preferably designed as a section of the protective cover provided in addition to the protective cover wall, which has the particular advantage thatthe holding devices, a force for fixing the protective cover to the mounting element or cistern can be applied without this risking damage to the protective cover wall and thus the tightness of the protective cover. The fixing devices can be designed, for example, as clamping devices, in particular screw clamps or elastic clamps. This can particularly preferably be accompanied by the holding devices being designed as a section of a flange or other surface section of the protective cover. The fixing devices are particularly preferably formed by the mounting element and / or the cistern or as separate elements from the mounting element and the cistern, which are fixed to the latter, in particular are releasably fixed. In one embodiment, the fixing elements are releasably latched and / or clamped to the mounting element. In one embodiment, the holding devices area section of the protective cover is formed which is more dimensionally stable than a section of the protective cover wall which borders the interior of the protective cover and which is adjacent to the holding devices. For example, the holding devices can be made of a more dimensionally stable plastic or can be thicker than the adjacent protective cover wall. As a result, the holding devices can be designed in a particularly suitable manner for reliably fixing the protective cover to the mounting element or cistern. In one embodiment, the holding devices are provided on a flange section or on a pocket- or tab-like section of the protective cover. As a result, it can be particularly advantageously realized that a section of the flushing device, by means of which it is fastened relative to the mounting element, is encompassed by the protective cover, while the fixing devices engage on this section, since this section with its outer siderespective holding device of the protective cover, so that a leak-free fixing of the protective cover and the flushing device to the mounting element can be enabled. In one embodiment, the flushing device has fixing devices by means of which it is fixed to the mounting element, wherein in each case one of the holding devices encloses one of the fixing devices. In this case, the holding device encloses the respective fixing device at least partially. Preferably, the respective fixing device is completely enclosed by a section of the protective cover, on the outside of which the respective holding device of the protective cover is formed. In one embodiment, in each case one of the fixing devices and one of the holding devices are fixed together to the mounting element by one of the fixing devices. This enables a leak-free fixing of both theThe fastening devices are preferably each engaged with a pair of holding devices and associated fastening devices, in which the respective fixing device only bears directly against the respective associated holding device and, due to the pocket-like enclosing of the section of the protective cover forming it, engages the respective fastening device, so that a particularly reliable and simple, and at the same time sealing, assembly of the rinsing device and the protective cover on the mounting element is enabled. In one embodiment, at least some of the holding devices are reversibly connected to theFixing devices connectable to and detachable from these to ensure the detachability of at least a portion of the protective cover from the mounting element, in particular to make the flushing device accessible from a front side of the mounting module. Particularly preferably, the holding devices are configured to correspond to the fixing devices in such a way that the holding devices are reversibly connectable to and detachable from the fixing devices, and thereby at least said portion of the protective cover is reversibly detachable from and reconnectable to the mounting element without the detachment or connection resulting in a change in the water conduction properties of the protective cover. The protective cover is thus configured to be sealing in the same way both in the state in which the holding devices are detachable from the fixing devices and in the state in which the holding devices are connected to the fixing devices. ParticularlyPreferably, the holding and fixing devices are designed as mutually corresponding locking elements or in the manner of a hook and hook receiving pair. This makes it particularly easy to detach the protective cover from the mounting element or cistern. In one embodiment, the protective cover is held at a distance from at least one water-conducting area of ​​the flushing device. For example, the flushing device can have a cistern which has a cistern wall which is designed to store flushing water and is thus designed as a water-conducting area of ​​the flushing device. For example, the flushing device can have a pipe section which carries water when the mounting module is used as intended, for example a pipe section of a pressure flusher which is connected to a water supply line when used as intended. By detaching the protective cover from the water-conducting areaspaced apart, thermal contact between the water-bearing area and the protective cover can be reduced due to the distance between the water-bearing area and the protective cover and thus the air provided within the distance. This has the particular advantage that even if - as is typically the case - cold water is arranged in the water-bearing area of ​​the flushing device, the formation of condensation on the outside of the protective cover is prevented as far as possible. In general, the flushing device can have a flushing device wall which, when the assembly module is used as intended, defines the water-bearing area in which water is arranged on its inside when used as intended, wherein the protective cover preferably comprises at least 90% of the surface of the outside of the wall in the water-bearing area, i.e. in an area in which, when used as intended, water is in thewall is arranged, is spaced apart. In one embodiment, a thermal protective cover is arranged between the protective cover and the flushing device or the protective cover is designed as a thermal protective cover. This can prevent the formation of condensation particularly effectively. By designing the protective cover itself as a thermal protective cover, for example by designing the protective cover from Styrofoam or from plastic with air chamber inclusions, the assembly module can be manufactured particularly inexpensively. In one embodiment, the protective cover is made at least in sections from an elastically stretchable material, wherein the stretchable material, when stretched from its rest position, rests against the flushing device with an elastic restoring force. To realize the assembly module, the flushing device is thus arranged in the interior of the protective cover in which the stretchable material is stretched. The protective cover is preferably made from an elasticmade of stretchable plastic. By making the protective cover from elastically stretchable material, on the one hand, inserting the flushing device into the protective cover or pulling the protective cover onto the flushing device can be made particularly easy and / or a particularly space-saving implementation of the mounting module can be made possible. In one embodiment, the mounting module has a multi-part mounting element with a first mounting element part and a second mounting element part, wherein the mounting element parts can be detachably connected to one another and wherein the protective cover is fastened exclusively to the first mounting element part. This has the particular advantage that, starting from a normal operating state of the mounting module in which the mounting element parts are connected to one another, the protective cover can be removed from a wall, while the second mounting element part remains fixed to the wall by detaching the first mounting element part from thesecond mounting element part is released, or that the first mounting element part can remain fixed to a wall together with the protective cover, while the second mounting element part, in particular together with other components of the mounting module, such as at least part of the flushing device or the water distributor, can be released and removed from the wall for maintenance purposes. For example, the second or second mounting element part can be permanently fixed to the wall for installation of the mounting module on or in a wall, while the first or first mounting element part can be released from the second or first mounting element part and thereby also from the remaining wall, which is particularly advantageous for maintenance purposes. The mounting element can, for example, also have a third mounting element part, wherein the first mounting element part is arranged between the second and third mounting element parts and can be released from both of them. Generally preferredThe mounting module comprises a mounting element, wherein at least a part of the flushing device, in particular the flushing device, and / or at least a part of the water distributor and / or at least a part of the protective cover, in particular the protective cover, is detachably attached to the mounting element. The mounting element can generally preferably be designed as a mounting frame, in particular a metal frame, with vertical struts and cross struts and, for example, when the mounting module is installed with mounting feet enclosed by it, can be firmly fixed to the floor of a room, in particular screwed to it, and furthermore can be fixed in a fixed position to a building wall with its vertical and / or cross struts, in particular screwed to it. The protective cover can be attached to the mounting element directly or indirectly via the flushing device, in particular via a cistern enclosed by the flushing device, which is attached to the mounting element.Preferably, the flushing device and / or the water distributor and / or the protective cover (or at least a respective part thereof) is detachably attached to a front side of the mounting element and can be removed from the front side of the mounting element. As a result, the flushing device and / or the water distributor and / or the protective cover can be removed from the mounting element in a particularly simple manner for maintenance purposes, while the mounting element remains unchanged in its position in the space. In one embodiment, at least a part of the flushing device, in particular the flushing device as a whole, is detachable from the mounting element and can be removed from it, while at least a lower section of the flush pipe and at least a part of the protective cover remains on the mounting element. Preferably, the remaining part of the protective cover forms the described inspection opening of the protective cover. This has the particular advantage thatWhen at least part of the flushing device is removed for maintenance purposes, the seal between the protective cover and the wall section of a wall surrounding the protective cover can remain untouched. Particularly preferably, the remaining part of the protective cover surrounds the said lower section of the flush pipe. Particularly preferably, the lower section of the flush pipe comprises the flush pipe bend of the flush pipe. Particularly preferably, the lower section of the flush pipe comprises the flush pipe socket of the flush pipe. An at least partial removability of the flushing device from the mounting element or from the protective cover while the lower section of the flush pipe remains can have the particular advantage that the flush pipe can remain connected to a flush pipe connection of a WC of a WC arrangement comprising the mounting module, while at least part of the flushing device is removed from the mounting element or from the protective cover. In aIn one embodiment, the drain pipe runs at least predominantly outside the protective sheath, preferably the drain pipe runs completely outside the protective sheath. This allows the structure of the protective sheath to be kept simple and still ensures that in the event of a leak in the water supply, the leaked water is discharged via the outlet opening. In one embodiment, the drain pipe is fastened outside the protective sheath to a mounting element of the mounting module. This allows the drain pipe to be fastened without the fastening of the drain pipe having to be taken into account when designing the protective sheath. In one embodiment, the water distributor can be fastened to a building wall by means of a mounting element of the mounting module and / or by means of the protective sheath. Thus, the water distributor can preferably be fastened to the building wall exclusively via the mounting element or the protective sheath.Preferably, the water distributor extends with its transverse extension at least predominantly within the transverse extension of the mounting element. This can ensure that the water distributor is fixed by means of the mounting element in a particularly advantageous manner. In one embodiment, the mounting element is designed as a mounting frame having a vertical strut on each of its transverse sides, wherein the water distributor is arranged with its transverse extension at least predominantly between the vertical struts of the mounting frame. The inventors have surprisingly found that the integration of a water distributor into a mounting module having a protective sheath as explained above is associated with particular advantages, since, on the one hand, the installation of the water distributor can be simplified, in particular by fixing the water distributor to a building wall via the mounting element, and, on the other hand, since the protective sheath can be usedcan be used to catch a leakage of the water distributor. In one embodiment, the flushing device is arranged at least predominantly in front of the water distributor. For example, the flushing device can be arranged in front of branch lines of the water distributor or in front of further line sections connected to the branch lines of the water distributor, so that the flushing device is accessible from the front of the assembly module, but not the branch lines arranged behind the flushing device or the further line sections connected thereto. The term "arrangement of an element "in front of" another element refers to an arrangement with respect to the sagittal direction in the direction from the back to the front; accordingly, the front of a section of an element is arranged "in front" of its back or its back is arranged "behind" its front. Preferably, less than 50% of the front of the flushing device isWater distributor is concealed, preferably the entire front side of the flushing device is not concealed by the water distributor. In one embodiment, the flushing device comprises a cistern which extends in a direction perpendicular to the vertical direction and the transverse direction, in this case mostly referred to as the sagittal direction, over less than 13 cm, in particular less than 12 cm, in particular less than 11 cm, in particular less than 10 cm, in particular less than 9 cm. While conventional cisterns have a considerable depth, i.e. extension length in the sagittal direction, the inventors have recognized that, especially when providing a protective sheath, and in particular when providing a water distributor, the realization of a cistern which is flat in the sagittal direction brings with it particular advantages. This is because the mounting module can still be easily integrated into a wall. The feasibility of such aA specialist can expertly design a cistern that is flat in the sagittal direction, for example, by providing a correspondingly wide or high cistern in order to ensure a sufficient water storage capacity in the cistern, and / or by providing a correspondingly narrow drain and fill valve. In one embodiment, the protective cover is designed in the manner of a cabinet that is open or can be opened at its front. The cabinet can, for example, be designed as a dimensionally stable plastic box as explained here. By designing the protective cover in the manner of a cabinet, on the one hand, sufficient stability of the protective cover can be ensured, for example, to enable the fastening of further components of the mounting element relative to the wall by means of the protective cover. In addition, by providing an opening, i.e. a cabinet that is open or can be opened at the front, a clearly definedInspection opening of the protective cover must be ensured.

Generally preferably, the protective cover has a vertical extension length of at least 60 cm, in particular at least 80 cm. By designing acorrespondingly large protective cover, the components of the assembly module can be arranged particularly advantageously in the protective cover and be accessible for maintenance purposes. The correspondingly large design of the protective cover has proven to be particularly advantageous for embodiments in which the assembly module has a water distributor. In this case, the water distributor is particularly preferably arranged relative to the flushing device in such a way that at least the central connection, in particular the shut-off valve of the central connection, in particular the shut-off valves of its branch lines, are arranged above the flushing device and within the interior of the protective cover and / or components of the water distributor, in particular branch lines of the water distributor, are arranged in the sagittal direction behind the flushing device and within the interior of the protective cover. The inventors have surprisingly found that by providing an assembly module which has aWater distributor, a flushing device and a protective sheath, an installation or assembly of the flushing device and water distributor in a wall of a room can be realized in a simple manner, with which the ingress of leaking water into the wall is prevented as far as possible.

For example, the further dispensing opening can be connected to the first casing part via the fluid line and via this to the dispensing opening, wherein the dispensing opening can dispense leakage water that has entered the first casing part from the further dispensing opening. Accordingly, it can be provided that the dispensing opening is designed to dispense leakage water into the second casing part and that the leakage water dispensed from the dispensing opening into the second casing part can be discharged through the further dispensing opening. In one embodiment, the mounting module has adjusting means that are arranged between the protective cover and the mounting element of the mounting module and by means of which the protective cover is fastened to the mounting element.

In this case, the adjustment means are preferably designed such that a position of the protective cover relative to the mounting element can be adjusted by means of the adjustment means, while the protective cover is fixed relative to the mounting element via the adjustment means. In this case, the adjustment means can be designed such that theyEnsure a pre-fixing state of the protective cover relative to the mounting element, in which a certain positional fixation of the protective cover relative to the mounting element is already ensured, whereas in the pre-fixing state the protective cover is still movable relative to the mounting element, whereas the adjustment means further enable the realization of a fixing state in that the protective cover is fixed in a fixed position relative to the mounting element by means of the adjustment means as explained and thus its position is also fixed with respect to the sagittal direction relative to the mounting element. The same positionability can of course also be provided for the flushing device or the water distributor by means of the adjustment means relative to the mounting element. The adjustment means can, for example, be designed as a sliding guide, wherein in the pre-fixing state displaceability via the sliding guide is ensured and in the fixing state theDisplaceability is prevented by jamming. For example, the adjusting means can also be designed as a locking or screw device. In general, the adjusting means are preferably designed such that the adjusting means ensure an adjustability of the position of the protective cover (and in particular of the flushing device and / or the water distributor) relative to the mounting element in the sagittal direction over a position range which is at least 3 cm, in particular at least 5 cm, in particular at least 7 cm in the sagittal direction. During the adjustability of the position within the position range, the adjusting means preferably ensure guidance of the protective cover (and in particular of the flushing device or the water distributor) relative to the mounting element. The adjusting means or the enabling of an adjustment of the position in the sagittal direction relative to the mounting element can have the particular advantagebring that the position, relative to the sagittal direction, can be adjusted taking into account the conditions provided in the wall, for example, taking into account the length of a paneling on the front side of the mounting element in the sagittal direction or the wall thickness of a wall paneling provided on the front side of the mounting element. The protective cover can thus be specifically positioned in its position, relative to the sagittal direction, in such a way that it can be particularly advantageously integrated into a sealing plane of the wall.

A supply connection assigned to the water connection is connected to a water supply line, in particular via the supply line connection of theMounting module. A supply connection assigned to the electrical connection is connected to an electrical supply line, in particular via the supply line connection of the mounting module. The shower facility supply line, in particular each of the preferably several provided shower facility supply lines, runs within the protective cover. Thus, the shower facility supply line preferably runs with at least a section within the protective cover, whereby a particularly compact design can be achieved. In one embodiment, the shower facility supply line is connected to a connection element arranged in the protective cover, i.e. in the interior of the protective cover, which has a connection for connection to a supply line. The connection element can, for example, be encompassed by the water connection or supply line connection.

In one embodiment, the shower device supply line runs through the protective cover and is connected to a connection element arranged outside the protective cover. When connected to a connection element arranged in the protective cover, any leakage water that occurs during this connection can be collected directly by the protective cover. Furthermore, the supply line connection of the assembly module can be used as the connection element, which, for example, is simultaneously the supply line connection for the flushing device. For example, the connection element can be formed by a water connection of a cistern of the flushing device, which is arranged in the protective cover and which is supplied with water via this water connection. In the described embodiment, it is particularly advantageous that the shower device supply line with its cross section lies within an opening cross sectionthe dispensing opening or extends offset from the dispensing opening to the outside from an interior of the protective cover, wherein it is particularly preferably arranged in an empty conduit which is encompassed by the mounting module and whose clear cross-section lies within an opening cross-section of the dispensing opening or which extends offset from the dispensing opening to the outside from an interior of the protective cover.

These dimensions preferably correspond to the dimensions of the preferably provided inspection opening of the mounting module. Preferably, the flushing device comprises a cistern, wherein the inspection opening and thus also the cover plate have a width and height that is greater than the width and height of the cistern. By providing aWith such a large inspection opening and such a cover plate, the flushing device and in particular the protective cover can be particularly easily accessible from the front of the mounting module, in this case from the front of the partition wall with which it defines the space. The cover plate can be enclosed by the mounting module, in particular fixed to the mounting element, in particular detachably and / or guided so as to be movable relative to it, or the cover plate can be a plate separate from the mounting module and mountable on the partition wall.

The invention further relates to a set for the implementation of an assembly module. The set comprises as components a flushing device, a supply connection, a flushing pipe element, a drain pipe and a protective cover. The flushing pipe element can form the flushing pipe or part of the flushing pipe of the assembly module to implement the assembly module. The assembly module can comprise further components, for example a mounting element, an empty pipe, etc. In every operating state of the set, the assembly module is formed by the components of the set. The flushing pipe element of the set comprises a flushing line and a branch connected to the flushing line. The set is for the implementation of a firstoperating state, in which an assembly module according to the invention is formed by the components of the set, wherein the flushing line is connected to a flushing water discharge opening of the flushing device and the discharge opening is connected to the branch for discharging leakage water by means of the branch into the flushing line. The set is further designed to implement a second operating state, in which the assembly module is implemented without a protective sheath and in which an air extraction device, which is included in the system as a further component, is connected to the branch - in comparison to the first operating state instead of the discharge opening - wherein, of course, the flushing line of the flushing pipe element is connected to a flushing water discharge opening of the flushing device, as in the first operating state. The set can thus enable a particularly cost-reduced implementation of different assembly modules, since identical parts are used.An assembly module can be produced which comprises a protective sheath and is designed as explained for the assembly modules according to the invention and in which the leakage water can be reliably discharged via the flushing pipe by means of the specially designed flushing pipe element with flushing line and branch. Furthermore, an assembly module can be designed in which no special sealing measures, i.e. no protective sheath, are provided, wherein the same, specially designed flushing pipe element can be used to ensure air extraction. The air extraction device can, for example, comprise a fan and / or an air extraction hose connected to a fan. The set is particularly preferably designed to implement a third operating state in which the assembly module is designed as an assembly module according to the invention and, as in the first operating state, the discharge opening is connected to the branch for discharging leakage water by means of the branch.into the flushing line, wherein the air extraction device is also connected to the branch. This can be ensured, for example, by the branch having two connections, a first connection for connecting the outlet opening and a second connection for connecting the air extraction device, or by the air extraction device being arranged in the protective cover and thus air extraction can take place via the branch via the outlet opening of the protective cover. The invention further relates to a use of an assembly module according to the invention for securing water-carrying connections when connecting a toilet, wherein the assembly module is set up in a room and a wall panel is provided in the room and then the toilet is connected to the flush pipe and the drain pipe of the assembly module, thereby ensuring that all leakage water flowing from the outlet opening is channeled into the room or into theDrain pipe flows. The wall cladding can be formed on a front side of a false wall. For example, the wall cladding can comprise tiles. By first setting up the mounting module in the room and providing the wall cladding, and only then connecting the toilet to the flush pipe and drain pipe of the mounting module, while ensuring that the leakage water flows in front of the wall cladding into the room or flows into the drain pipe, a particularly simple connection of a toilet can be made possible while ensuring that leakage water is prevented from entering a building. The invention is explained in more detail below with reference to eleven figures using exemplary embodiments.

Figure 1, comprising Figures 1a, 1b and 1c, shows an example of a generic mounting module 10 (Figures 1a and 1c) and a generic toilet arrangement 100 (Figure 1b) in principle representations. Such a mounting module, which is typically known in the prior art, has a mounting element 1, which can be fastened in the usual way relative to a wall of a building. In the exemplary embodiment shown here, the mounting element 1 is designed as a mounting frame with vertical struts and transverse struts or cross struts. Such a design of the mounting element 1 is very frequently used in the prior art, since it can be used toIn a simple manner, a robust mounting element can be realized which can be fixed relative to a wall using simple measures, for example, by means of height-adjustable mounting feet shown in Figure 1, fastened to a floor of a room and fastened to the wall by means of further mounting elements, as shown, for example, for embodiments according to the invention in Figures 2a, 3a, 9a and 6b. However, other designs of the mounting element are also known, for example a design as a built-in box, which, particularly in wet construction, can be arranged in a recess of a wall and fixed to the wall. In Figure 1, the vertical direction Z, the transverse direction Y and the sagittal direction X are shown as three spatial directions perpendicular to one another. When such a mounting module 10 is used as intended, the mounting module 10 is usually aligned such that the vertical direction Z is parallel to theEarth's gravitational force, and is aligned such that the sagittal direction X runs at least substantially parallel to a surface normal of the surface of the wall facing the room, into which the mounting module 10 is installed. In the illustrated embodiment of a mounting module 10 known as typical in the prior art, the mounting module 10 comprises a flushing device 2 having a cistern. The cistern has a cistern wall in which flushing water can be stored. At the bottom of the cistern wall, a flushing water outlet is provided in the form of an opening which can be reversibly closed by a drain valve of the flushing device 2. The drain valve can be actuated via an actuating device 20 by means of a commercially available actuating plate. The flushing device 2 further comprises a filling valve which is connected to a supply connection of the mounting module 10 designed as a water connection, to which a building-sideWater supply line can be connected. Such a typical mounting module 10 also usually has a flush pipe 3, which is fluidically connected to the flush water outlet of the cistern of the flushing device 2. Usually, a first pipe section of the flush pipe 3 is manufactured integrally with the cistern, with further pipe sections of the flush pipe 3 adjoining this first pipe section, in particular a flush pipe bend, which forms a flush pipe socket of the flush pipe 3, which is connected to a flush connection 53 of a toilet 5 by means of a flush connection pipe 30, as shown in Figure 1b. The flushing device 2 and the flush pipe 3 are usually fixed in a fixed position to the mounting element 1. Furthermore, a drain pipe 4 is usually fixed in a fixed position to the mounting element 1, which forms a drain pipe socket, which is connected to a drain connection 54 of a toilet 5 by means of a drain connection pipe 40.as shown in Figure 1b. In the toilet arrangement, as shown, for example, in Figure 1b, the flush pipe 3 and the drain pipe 4 of the mounting module 10 are thus fluidly connected to one another via the toilet 5 connected to the mounting module 10, since flush water which is discharged from the flushing device 2 via the flush pipe 3 into the toilet 5 passes through the toilet 5 to the drain pipe 4. Furthermore, a typical mounting module 10 often has, on the one hand, a water connection 23 as a supply line connection and, furthermore, an empty pipe 6 which emerges from the cistern of the flushing device 2 and leads to a front side of the mounting module 10. This can be seen from the combination of Figure 1a, which shows a front side of the mounting module 10 in an oblique view, and Figure 1c, which shows a rear view of the mounting module 10 in an oblique view. Through such an empty pipe 6, for example, a water pipe which is connected to the flushing device 2 within the cistern can bethe water connection 23 of the flushing device 2, are led to the front of the mounting module 10 and serve there, for example, to supply a shower toilet with tap water. Figure 2, comprising Figures 2a, 2b and 2c, shows an embodiment of an inventive mounting module 10 in various schematic diagrams. The inventive mounting module 10 can generally preferably be used together with a toilet 5 to realize a toilet arrangement 100, as shown by way of example in Figure 1b. Components of the mounting module 10, which are already provided with reference numerals in Figure 1 with reference to a mounting module 10 known as typical, are provided with corresponding reference numerals in the description of inventive embodiments, and with regard to the explanation of these components, reference is made to the corresponding description of Figure 1. In contrast to the known from the prior art shown in Figure 1The assembly module 10 of the embodiment shown in Figure 2, like all assembly modules 10 according to the invention, has a protective sheath 7 that surrounds the flushing device 2 of the assembly module 10, so that leakage water escaping from the flushing device 2 or at a connection of the flushing device 2 can be collected by the protective sheath 7 surrounding the flushing device 2. In a particularly advantageous embodiment, as shown by way of example in Figure 2, the protective sheath 7 completely surrounds the flushing device 2, except for an actuation opening 71 of the protective sheath 7, a connection opening 75 of the protective sheath 7, and a discharge opening 72 of the protective sheath 7, and is thus continuously closed. The discharge opening 72 is provided, as can be seen from Figure 2a, on the front side of the assembly module 10. The discharge opening 72 is enclosed circumferentially by a sealing flange 720. In the present embodiment, the sealing flange is720 is formed integrally with the protective cover 7. However, other configurations are also possible in which the sealing flange 720 can be slid sealingly onto a channel wall of the protective cover 7 in the manner of a slide-on sealing sleeve, as explained in detail here. The sealing flange 720 can be sealingly integrated into a sealing plane of the wall, which faces the space delimited by the wall, so that leakage water can be guided through the discharge opening 72 in front of the sealing plane and thus runs into the space visibly for a user, so that the leakage can be detected and subsequently remedied. By fluid-conducting the sealing flange 720 via a channel wall 721 of the protective cover 7 to an interior region of the protective cover 7, in which the flushing device 2 is arranged, the collected leakage water can be reliably discharged via the discharge opening 72 to the front of the mounting module 10. The provision of aSuch a channel wall 721 of the protective sheath 7, which fluidically connects the sealing flange 720 to the aforementioned interior area in which the flushing device 2 is arranged, is generally advantageous according to the invention. An installation channel with a corresponding channel wall 711 and a corresponding flange 710 is further provided around the actuation opening 71 of the mounting module 10 in the described embodiment. By incorporating the flange 710 into a sealing plane as explained above, the penetration of splash water into the wall can be particularly advantageously prevented, in particular also splash water that reaches the actuation opening 71 from the room. While in Figures 2a and 2b the protective sheath 7 is shown in dashed lines, in Figure 2c it is indicated by dashed lines and thus shown transparently, so that the components of the mounting module 10 arranged within the protective sheath 7 are also more clearly visible.are. From a view of Figures 2a, 2b and 2c together, it can be seen that the mounting module 10 further comprises a fastening device comprising a clamp 8 and a fan-shaped ring 80. With this fastening device, on the one hand, the flush pipe 3 is held on the mounting element 1 and, on the other hand, the protective cover 7 is held fixed relative to the mounting element 1. The fan-shaped ring 80, with its radial inner side, forms a fastening section of the fastening device, with which the fastening device bears against the flush pipe 3, wherein the fan-shaped ring 80 further forms vertical passages of the fastening device offset from this fastening section. The vertical passages, i.e., which extend from a top side to a bottom side of the fan-shaped ring 80 and thus also of the fastening device, enable leakage water to drain vertically downwards through the fan-shaped ring 80 towards the discharge opening 72.The protective sheath 7 is arranged on a radial outer side of the fan ring 80, in that the clamp 8 presses the protective sheath 7 against the outside at the level of the fan ring 80. From Figure 2c it is further apparent that the mounting module 10 has fixing devices 8, which in the present embodiment are detachably fixed to the mounting element 1 and which in the present case bear exclusively against an outer side section of the protective sheath 7, i.e. only against an outer side of the protective sheath 7. The functionality of such fixing devices 82, which are advantageously provided in the embodiments, is explained in more detail below with reference to Figure 10. From a view of Figures 1c and 2c together it is apparent that in a conventional flushing device, tabs 22 are typically provided, which are fastened to the mounting element 1 by screws as fixing devices. In the embodiment according to Figure 2, such tabs 22 are also provided on theCistern of the flushing device 2, but these tabs 22 are enclosed by the protective sheath 7, and the fixing devices 8 encompass the tabs 22 together with the area of ​​the protective sheath 7 surrounding the tabs 22, which thus acts as a holding device corresponding to the respective fixing device 8, so that the fixing devices 8 jointly fasten the flushing device 2 and the protective sheath 7 to the mounting element 1. Figure 3, comprising Figures 3a and 3b, shows a further embodiment of an assembly module 10 according to the invention in schematic principle representations. In addition to the components of this embodiment already described, this embodiment of the assembly module 10 according to the invention has an empty pipe 76, which is connected with one empty pipe end to the connection opening 75 and thus opens into the interior of the protective sheath 7, and which with its other empty pipe end 760 is protruding from the front of the assembly module 10accessible into this front side of the mounting module 10. In the embodiment shown in Figure 3, the empty pipe 76 is manufactured integrally with the protective sheath 7 as a single, coherent component made of plastic. In the described embodiment, however, the empty pipe 76 forms a volume separated from the interior of the protective sheath 7, which is generally advantageous according to the invention, wherein, starting from the empty pipe end 760 accessible from the front side, a line, for example a water line, in particular a DN10 reinforced hose, and / or an electrical line can be led to the connection opening 75. The connection opening 75 is generally preferably arranged at the supply connection, i.e. water and / or electrical connection, of the mounting module 10, so that, starting from the connection opening 75, the corresponding line can be easily connected to the corresponding connection. Generally, it has been found particularly advantageousIt has been found that at least at the level of the empty pipe end 760 accessible from the front, the internal volume of the empty pipe 76, i.e. its clear cross-section, is separated from the interior of the protective sheath 7. In the present case, the clear cross-section of the empty pipe 76 is surrounded by an empty pipe wall over the entire pipe extension length of the empty pipe 76, wherein the empty pipe wall delimits the clear cross-section from the interior of the protective sheath 7 and thus simultaneously delimits the interior of the protective sheath 7 with a section. As can be seen from Figure 3, the discharge opening 72 and the empty pipe end 760 open towards the front of the assembly module 10 are jointly enclosed by a sealing flange 720 of the assembly module 10. Figure 3b further shows that the empty pipe 76 has an empty pipe section 761, the clear cross-section of which extends in a direction from the open empty pipe end 760 accessible from the front toother empty conduit end, so that this empty conduit section 761 is designed in the manner of a funnel. This is generally particularly advantageous, since it simplifies the insertion of a line from the empty conduit end 760 located at the front to the other empty conduit end. Figure 4, comprising Figures 4a and 4b, shows a further embodiment of an assembly module 10 according to the invention schematically in various principle representations. The embodiment according to Figure 4 differs from the embodiment according to Figure 3 primarily in that the empty conduit 76 is manufactured as a separate component from the protective sheath 7 and thus runs at a distance from the protective sheath 7 over the vast majority of its pipe extension length. The empty conduit 76 of the embodiment according to Figure 4 is connected via an empty conduit connection 762 to the connection opening 75 of the protective sheath 7 and thus opens into the interior of theProtective cover 7. With its empty conduit end 760 accessible from the front, it is offset, but arranged directly adjacent to the dispensing opening 72 and, together with the latter, is enclosed all the way around by the sealing flange 720. In a further embodiment, not shown, such a separate empty conduit 76 can, for example, also run completely within the protective cover 7, wherein the empty conduit 76 in this case delimits an empty conduit volume from the interior of the protective cover 7, which is arranged within the interior of the protective cover 7. Furthermore, in such an embodiment, the empty conduit end 760 of the empty conduit 76 accessible from the front of the mounting module 10 can be arranged within the clear cross-section of the dispensing opening 72. Figure 5, comprising Figures 5a and 5b, shows two further embodiments of an inventive mounting module 10 schematically in various schematic representations. Each of theseEmbodiments each have a signaling device 77, 78, which is arranged at a location in the protective cover, i.e. within the interior of the protective cover, and is designed to output a signal upon detection of water at this location. The signaling device 77 of the embodiment shown in Figure 5a is designed as an electronic signaling device 77, which electronically dictates the presence of water, for example due to a reduced resistance between contacts of the signaling device 77. In one embodiment, the signaling device 77 is designed to output an electrical signal as a signal upon detection of water, which is converted into an acoustic signal, for example into an alarm tone that is easily perceptible by a user. In one embodiment, the signaling device 77 is designed to output at least one electrical signal as a signal, which is forwarded to a network and then in the networkcan be processed. For example, the signaling device 77 can be designed as an IoT device that wirelessly feeds a corresponding electrical signal into a network, from which the signal can be taken as a warning signal. For example, service providers, such as installers, can be connected to the network, so that the time during which a leak is present can be particularly advantageously reduced by the output of the signal. In the embodiment shown in Figure 5b, the signaling device 78 is designed as a water-soluble tab. Generally, the signaling device 78 is preferably arranged at a location on the protective cover 7 where the leaking water necessarily collects before it can be discharged via the discharge opening 72. When a leak occurs, leaking water thus reaches the signaling device 78 and is colored by it, so that the leaking water emerges colored at the front of the mounting module andcan thus be recognized as a color change on the front side of the mounting module. This can be particularly advantageous for a wide variety of applications, in particular for applications in which the dispensing opening 72 is fluidically connected to the flush pipe 3 of the mounting module 10, since in such a case, the escape of the colored leakage water in the flushing chamber of the toilet 5 can be particularly advantageously detected. Figure 6, comprising Figures 6a and 6b, shows a further embodiment of an inventive mounting module in schematic principle representations. Figure 6a shows a view of the front side, Figure 6b shows an oblique view of the front side and an enlarged view of an area X of the mounting module 10. In the embodiment according to Figure 6, an empty pipe 76 is provided which, similar to that explained for Figure 3, is manufactured integrally with the protective cover 7. The fastening device of the mounting module 10 isparticularly advantageously designed, as can be seen in particular from Figure 6b, in which the protective sheath 7 is transparent and thus only shown by dashed lines. The fastening device has a clamp 8 and a fan ring 80, wherein the fan ring 80 has several vertical passages and a specific passage 876 of these vertical passages is designed to correspond to the empty pipe 76, so that the empty pipe 76 is reliably held on the mounting element 1 by the fastening device, without the empty pipe 76 being squeezed with a significant reduction in its clear cross-section at the level of the fastening device. Figure 7, comprising Figures 7a and 7b, shows a further embodiment of a mounting module 10 according to the invention in schematic principle representations. In Figure 7a, unlike in Figure 7b, the protective sheath 7 is transparent and thus only shown by dashed lines. In the embodimentAccording to Figure 7, the discharge opening 72 does not open directly into the front of the mounting module 10, but rather opens into a branch 37 of the flush pipe 3, which is connected to a flushing line 38 of the flush pipe 3. Thus, leakage water discharged from the discharge opening 72 can be discharged through the flush pipe 3 into a toilet 5 connected thereto, so that it does not reach a spatial boundary of the room in which the mounting module 10 is arranged or a toilet arrangement 100 is realized with such a mounting module 10. By arranging the discharge opening 72 below the flushing water outlet of the flushing device 2, but above the point where the branch 37 joins the flushing line 38, it can be ensured that the leakage water is sufficiently discharged into the flushing pipe 3 through the discharge opening 72, and on the other hand it can be ensured that during a flushing process, flushing water splashing back from the flushing pipe 3 only contributes slightly to theDischarge opening 72. In a particularly advantageous embodiment, the flushing line 38 and branch 37 form a flushing pipe element that can be used flexibly, wherein in a first application variant, the discharge opening of a protective sheath 7 of the assembly module is connected to the branch 37, and in a second application variant, an air extraction device, and not the discharge opening 72 of a protective sheath 7, is connected to the branch 37. The embodiment according to Figure 7 further comprises a protective element 130, which is trough-like or tube-like and is designed to guide leakage water emerging from the flushing pipe 3 to the front of the assembly module 10. Such a protective element 130 can, according to the invention, generally advantageously be provided as a casing part of the protective sheath 7, which is designed as a separate component from the casing body of the protective sheath 7 enveloping the flushing device 2. While in the present embodiment and generallyAdvantageously, the casing body ends above the flush pipe bend and thus above the flush pipe socket of the flush pipe 3, to which the flush connection pipe 30 is intended to be connected, the protective element 130 engages under, in particular surrounds, the flush pipe socket of the flush pipe 3 and can thus discharge leakage water escaping at the transition between the flush connection pipe 30 and the flush pipe 3 to the front of the assembly module 10. Generally preferably, a sealing flange 720 as explained above can be provided on the protective element 130. Generally preferably, the protective element 130 can be designed as a construction protection that remains on the assembly module 10 even after installation has been completed, wherein the construction protection has, in addition to the protective element 130, a removable cover that closes the drain pipe 4 and the flush pipe 3 during a construction period to protect them, wherein in particular the protective element 130 protects both the flush pipe 3 at the level of its flush pipe socket and the drain pipe 4 at the level of itsDrain pipe socket at least engages under, in particular engages around, so that at the transition between the flush pipe socket and the flush connection pipe 30 and at the transition between the drain socket of the drain pipe 4 and the drain connection pipe 40, leaking water can be drained to the front of the assembly module. This can be particularly advantageous if the discharge opening 72 opens into the flush pipe 3. Figure 8, comprising Figures 8a and 8b, shows a further embodiment of an assembly module 10 according to the invention schematically in various principle representations. In this embodiment, as well as in the embodiment according to Figure 7, the discharge opening 72 does not open into the front of the assembly module 10, but the discharge opening 72 is connected to the flush pipe 3 in a fluid-conducting manner. In deviation from the embodiment according to Figure 7, however, the embodiment according to Figure 8 provides that the discharge opening 72 is located between a pipe wall 33, which has a clearCross-section of the flush pipe 3, and opens into a wall section 34 located within this clear cross-section of the pipe wall 33. Both the pipe wall 33 and the wall section 34 are each formed by a pipe section of the flush pipe 3, wherein these two pipe sections 33, 34 are connected to one another, but passage openings 35 are provided between them. Thus, leakage water, which is discharged via the outlet opening 72 between these two pipe sections 33, 34, can flow through the passage openings 35 and be guided through the flush pipe 3 to a toilet 5 connected to the mounting module 10. In the particularly advantageous embodiment shown in Figure 8, a check valve 73 is further provided as a further wall section within the clear cross-section enclosed by the pipe wall 33. This configuration particularly effectively prevents the water from the flush pipe 3 from flowing into the interior via the outlet opening 72the protective cover 7. Even if the flush water backs up in the flush pipe 3 as far as the cistern 21 shown in Figure 8b, the non-return valve 73 prevents the thus backed-up water from entering the interior of the protective cover 7 via the discharge opening 72. At this point, the enlarged section shown in Figure 8 will be briefly discussed. This section shows that the flushing device 2, as is generally advantageous according to the invention, comprises a cistern 21 in which a drain valve 24 is arranged, which, in the closed state, rests with its seal on the edge surrounding the flush water outlet, i.e., the opening provided in the bottom of the cistern wall. This closed state is shown in Figure 8b. In the open state, this seal of the drain valve 24 is spaced from this edge, so that water can flow through the flush water outlet of the cistern 21 into the flush pipe 3. In Figure 9, comprisingFigures 9a and 9b show schematically illustrated basic diagrams of a further embodiment of an assembly module 10 according to the invention. Figure 9a shows an oblique view of the rear side of the assembly module 10, wherein the protective cover 7 is transparent and thus only shown with dashed lines, whereas Figure 9b shows a vertical view from above of the assembly module 10 and, for explanatory purposes, the upper left side is shown open so that components of the assembly module 10 located within the protective cover 7 or the cistern 21 are visible for explaining the described embodiment. Compared to the other embodiments, in the embodiment according to Figure 9, the supply connection or the water connection 750 of the supply connection of the assembly module 10 is specially designed. The water connection 750 is arranged at the connection opening 75 of the protective cover 7. The water connection 750 has an outer elementcomprising a connection component 751 and a mounting component 752. With the mounting component 752, the outer element is fixed to the protective sheath 7 around the connection opening 75, sealing it relative to the outside of the protective sheath 7. The outer pipe 51 of a water supply line, which in this case and generally advantageously is designed as a corrugated pipe, is connected to the outer element as intended. The water connection 750 further comprises an inner element, which is designed for connection to an inner pipe 52 of the water supply line, which is typically designed as a pressurized water-carrying supply line of a building, whereas the outer pipe 51 serves merely to collect leaks. The inner element has a mounting component 753, with which it is fixed to the cistern wall of the cistern 21, as well as a shut-off valve 254, which is held in a fixed position on the cistern 21 by the mounting component 753 of the inner element.and that can be closed and opened via an operating device 755, wherein a line 756 of the flushing device 2 is connected to the shut-off valve 754, which connects the shut-off valve 754 and, via this, the inner pipe 52 to a filling valve of the flushing device 2. In an embodiment not shown, the inner element and the outer element are not connected to one another. In the present exemplary embodiment, a hollow cylindrical line guide is provided between the outer element and the inner element, which has an opening in its cylinder wall on its underside (not shown in Figure 9b), so that leakage water discharged from the outer pipe 51 to the protective sheath 7 reaches the interior of the protective sheath 7 between its inner side defining the interior and the outer side of the cistern wall of the cistern 21. This leakage water can thus also be discharged via the discharge opening 72, which is provided according to the invention in the assembly module 10. InFigure 10, comprising Figures 10a, 10b and 10c, shows further embodiments of a mounting module 10 according to the invention or of components thereof in schematic principle representations. In Figure 10a, the mounting module 10 is shown in an oblique view of its rear side, i.e. rear side. The protective cover 7 is transparent and thus only shown by dashed lines so that the flushing device 2 with the cistern 21, which is arranged within the protective cover 7, is visible. From Figure 10a, it can be seen that the cistern 21 of the flushing device 2 has lateral tabs 22, via which it can be fastened to the mounting element 1, as already explained above, for example, for the cistern known from the prior art with reference to Figure 1c. The cistern 21 has two such tabs 22 on each of its transverse sides, of which only one is visible in Figure 10a due to the oblique view, which tabs 22 extend in the vertical direction.Z are arranged one above the other. In Figure 10a, to illustrate the fixation of the flushing device 2 and the protective cover 7 to the mounting element 1, one of the tabs 22 is shown without an associated fixation device 82, whereas the other of the tabs 22 is not visible in Figure 10a, since it is encompassed by the fixation device 82. The protective cover 7, together with the flushing device 2, is fixed to the mounting element 1 via the fixation device 82, in which the protective cover 7 rests with a section of its inner side against one of the tabs 22, and the fixation devices 82 encompass the section of the outer side of the protective cover 7 opposite this section of the inner side, which section forms a holding device for the protective cover 7. The fixation device 82, which is used in the embodiment of a mounting module 10 shown in Figure 10a, is shown enlarged in Figure 10b. The fixation device is designed in the manner of a retaining clip,which has a film hinge 822 on one side and a locking device 821 on the other side. By pivoting the two sections of the holding clip or the fixing device 82 connected to one another by the film hinge 822, the holding device of the protective cover 7 and the respectively associated tab 22, which forms a fastening device of the flushing device 2, can be encompassed together with these two sections. On its side facing the mounting element 1, the fixing device 82 has locking lugs, which are locked into locking recesses of the mounting element 1 for fixing the respective fixing device 82 and, via this, the flushing device 2 and the protective cover 7. Figure 10c shows schematically in two views the fixing device 83 of a further embodiment of an assembly module 10 according to the invention. This fixing device 83 has a recess in which a tab 22 of the cistern 21, enclosed by the protective cover 7, of theFlushing device 2 can be accommodated. Adjacent to this recess, the fixing device 83 has at least one section with a cutout through which a fixing means 84 can be inserted to connect the fixing device 83 to the mounting element 1. In the particularly preferred embodiment shown in Figure 10, a section with such a cutout is provided on two sides of the recess in which the tab 22 is arranged together with the section of the protective cover 7 enclosing it, so that the fixing device 83 can be fixed to the mounting element 1 on both sides of this recess via a fixing means 84. In Figure 11, comprising Figures 11a, 11b and 11c, a further embodiment of a mounting module according to the invention is shown schematically in various schematic representations. The mounting module 10 is characterized by a special design of its installation channel. TheThe installation duct has a duct wall 711 and a flange 710. The flange 710 is formed by a sealing sleeve 713. The sealing sleeve 713 has a first region 714 with which it rests against the duct wall 711, and a second region with which it extends laterally away from the duct wall, wherein the second region completely encloses the first region and is formed by the flange 710. The sealing sleeve 713 thus has an opening in which the duct wall 711 is arranged, wherein the sealing sleeve 713 rests with the second region 714 in a sealing manner against the outside of the duct wall 711. The first region has, on the one hand, a support section made of a rigid material, and on the other hand, an elastic sealing lip with which it presses against the duct wall 711 from the outside. As can be seen from the combination of Figures 11a and 11b, the sealing sleeve 713 is positioned along the direction of the installation duct on theThe channel wall 711 can be pushed onto it and can slide sealingly along the channel wall 711. The channel wall 711 has a plurality of webs 712 arranged one behind the other in the direction of channel extension, which are sealingly connected to one another, wherein, however, between each two adjacent webs 712 there is provided a separating groove in which the channel wall 711 has a smaller material thickness than in the region of the webs 712. Furthermore, the webs 712, generally advantageously, each have a tear-off tab, which is not shown in Figure 11. By pulling the tear-off tab on one of the webs 712, the web can be separated from its neighboring webs 712, whereby the channel wall 711 can be cut to a specific length, which is generally advantageous according to the invention. When installing the assembly module 10 according to Figure 11, the duct wall 711 can first be cut to length and then the sealing sleeve 713 can be attached to the duct wall 711,which is generally advantageous according to the invention. This makes it possible, in particular, for the mounting module 10 to be paneled on the front side of its mounting element 1, for example with plasterboard, after which the sealing sleeve 713 can then be connected to the duct wall 711, which is generally advantageous according to the invention. As a result, the paneling can be carried out particularly easily and, moreover, can be brought so close to the duct wall 711 in a particularly simple manner that a particularly reliable sealing of a gap between the duct wall 711 and the paneling can be achieved in a simple manner via the flange 710. The sealing sleeve 710 has an opening that is aligned with the clear cross-section of the duct wall 711, which is generally advantageous according to the invention. From Figure 11c it can be seen that this opening or this clear cross-section of the duct wall 711, generally advantageous according to the invention, inTransverse direction Y is considerably longer than in the vertical direction Z, which is particularly advantageous for the arrangement of an actuating device. In the state shown in Figure 11c, the clear cross-section of the installation channel or its channel wall 711 is closed by a protective plate 25, which is removable from the channel wall 711, which is generally advantageous according to the invention. The protective plate 25 can protect the interior of the installation channel and thus also access to the cistern 21 of the flushing device 2 during construction and can then be removed so that a conventional actuating plate can be used in a professional manner. While Figure 11 shows an embodiment in which the sealing sleeve 713 can be applied in a sealing manner via an elastic sealing lip on the outside of the side wall 711 by sliding it onto the side wall 711, other embodiments are of course possible, for example a sealthe sealing sleeve 713 relative to the channel wall 711 by means of a sealing adhesive tape or other adhesive, in particular on the outside and / or inside of the channel wall 711. Furthermore, in other embodiments, a differently configured adjustability of the channel length of the channel wall 711 is possible, so that, for example, instead of the webs 712 provided in the embodiment according to Figure 11, the length changeability can be realized by providing a telescopic channel wall 711 and / or by providing an easily cut channel wall 711. Figure 12 shows various schematic principle representations, on the one hand, the view of a front side of an embodiment of an assembly module 10 according to the invention and, on the other hand, an enlarged section of the assembly module 10. The embodiment according to Figure 12 has, in addition to the flushing device 2, a water distributor 9 with a cold water distributor and a hot water distributor.The cold water distributor has a cold water central connection 91 as a first central connection of the water distributor 9. The hot water distributor has a hot water central connection 92, which forms a further central connection of the water distributor 9. The water distributor 9 has, on the one hand, branch lines 910 branching off from the cold water central connection 91, each of which comprises a shut-off valve 911 assigned to it. Furthermore, the water distributor 9 has, as further branch lines, hot water branch lines branching off from the hot water central connection 92 and likewise each of which comprises a shut-off valve 911 assigned to it. Furthermore, both the cold water central connection 91 and the hot water central connection 92 each have a shut-off valve 911. The water distributor 9 extends with a considerable section in the vertical direction Z above the flushing device 2 and thus above the cistern of theFlushing device 2. The water distributor 9 and the flushing device 2 are arranged together in the protective cover 7 of the assembly module 10. In the present case, the protective cover 7 is designed in the manner of a cabinet that is open at its front. The protective cover 7 thus has a large inspection opening through which both the flushing device 2 and the water distributor 9 are accessible. Furthermore, the flushing device 2 can be removed from the protective cover 7 via the inspection opening. The protective cover 7 is preferably formed by a dimensionally stable plastic box. In the described embodiment, the assembly module 10 has a sealing sleeve (not shown in Figure 12), which is connected to the protective cover around the inspection opening of the protective cover and which projects beyond the protective cover 7 in the vertical and transverse directions Y, Z. In a particularly advantageous embodiment, as shown in Figure 12, the protective cover 7 has aInspection opening has a flange surrounding the inspection opening, to which the sealing sleeve is attached. The sealing sleeve allows the front side of the protective cover 7 to be integrated all the way around the inspection opening in a sealing plane of a wall in which the mounting module 10 is mounted. Generally preferably, the module 10 has adjustment means by means of which the protective cover 7 can be adjusted relative to the mounting element 1 along the sagittal direction, while it is held unchanged on the mounting element 1. As a result, the position of the front side of the protective cover 7 can be specifically adapted in the sagittal direction to a wall thickness or wall cladding thickness present in the sagittal direction X. Generally preferably, the mounting module 10 further comprises a cover plate, by means of which the inspection opening can be reversibly closed. The cover plate does not necessarily have to be sealed against the protective cover 7, since water escaping from the inspection opening can generally bethe seal of the protective cover 7 around the inspection opening can only reach a wall and thus cannot lead to undetected moisture penetration into the wall. In the described, particularly advantageous embodiment, the protective cover 7 furthermore forms a receiving tray with a tray bottom in its lower end region, so that leakage water can be collected on the tray bottom. In the enlarged illustration according to Figure 12, this tray bottom is shown with the opening provided therein, into which the flushing pipe 3 of the assembly module 10 is sealingly inserted. The flushing pipe 3 has a pipe section 31, which is connected to the flushing water outlet of the flushing device 2, as well as a pipe section 32, which delimits a clear cross-section of the flushing pipe in an area within which the pipe section 31 is arranged. Leakage water that collects on the tray bottom of the protective cover 7 can thus be collected between the pipe section31 and the pipe wall formed by the pipe section 32, enter the flush pipe and are discharged to the toilet through the flush pipe bend 36, which is connected to the pipe section 32. A non-return valve 73 particularly advantageously prevents flush water from the flush pipe 3 from passing through the outlet opening 72 into the protective cover 7.
