Description

The invention relates to a mounting module for mounting a cistern and a method for realizing a pre-wall in front of such a mounting module as well as a method for realizing a WC installation with a WC body installed on a front side of a pre-wall.

Generic mounting modules are widely known in the art and are mostly used for mounting a cistern behind a pre-wall. The mounting module extends along a vertical line with a height and along a transversal line with a width and forms a front side, wherein the pre-wall is usually arranged on the front side of the mounting module extending along the vertical and transversal lines. The pre-wall can have openings through which elements of the mounting module extend, so that the pre-wall is only arranged in front of sections of the front side of the mounting module and further sections of the mounting module extend in front of the pre-wall, so that they form pre-wall side sections of the mounting module, which are arranged in front of the pre-wall. The term front side always refers to the side of the mounting module to which a WC body is intended to be attached to the mounting module and to which with a viewing direction that runs perpendicular to the vertical and the transverse. To attach the toilet body, the mounting module usually has fastening rods that are firmly mounted to a module frame of the mounting module and onto which the toilet body can then be pushed, while the fastening rods are inserted into corresponding openings in the toilet body, after which the toilet body is finally fastened to the fastening rods by means of fixing devices that correspond to the fastening rods, for example comprising a nut and/or a clamping unit. A cistern usually comprises an actuating device for triggering a toilet flush, which is usually integrated into a cover plate that closes a reversing opening provided in the cistern. Generic assembly modules usually comprise a module frame, a drain pipe and a cistern with a flush pipe, wherein in an operating position of the assembly module the cistern is attached to the module frame and the flush pipe forms a flush pipe connection open at the front of the assembly module and the drain pipe is attached to the module frame and forms a drain pipe connection open at the front of the assembly module. The operating position refers to a specific arrangement of the components of the assembly module relative to one another. In the operating position, the flush pipe connection and the drain pipe connection of the assembly module are accessible from the front, so that in the operating position of the assembly module a toilet body with its flush water inlet connection and its waste water outlet connection can be connected to the flush pipe connection and the drain pipe connection from the front of the assembly module.

Generic mounting modules are suitable for the particularly simple installation of a toilet. The provision of the module frame, which usually has at least two vertically running support struts and at least two transverse struts connecting the support struts, enables easy installation of the cistern and a toilet body in a room. This is because the module frame can be placed with its vertical underside on a room floor and fixed to the room floor and in particular to a wall bordering the room, for example the supporting structure for a drywall or a building wall, so that a cistern fixed to the module frame and a toilet body fixed to the module frame can be arranged in a simple and reliable manner in a room. At the same time, by attaching the flush pipe and the drain pipe to the module frame, the module frame can reliably determine the positions of these pipes in the operating position. The drain pipe, which is attached to the module frame, usually opens into a building-side sewer line at its vertically lower end. After the drain pipe of the assembly module has been connected to the building's wastewater line and the cistern has been connected to at least one building-side water supply line and, in particular, to a building-side electrical supply line, a pre-wall can then be created in front of the module frame and thus at least partially in front of the assembly module. Such a pre-wall is usually realized as a drywall. The pre-wall comprises a building board, for example, a plasterboard, and UW and CW profiles are usually used as the supporting frame for the pre-wall, to the front of which the building boards of the pre-wall are mounted. Generic assembly modules usually have a module frame, which in such UW or CW profiles. These generic mounting modules thus enable reliable fixation and connection of a cistern before the pre-wall is installed. After the pre-wall is completed, which usually includes building panels as well as tiles applied to the front of the building panels, a toilet body can be mounted on the front of the pre-wall and easily connected to the cistern's flush pipe connection and the drain pipe connection.

Such assembly modules must therefore remain in a room for an extended period during the construction period, once the drainpipe and cistern have been connected to the corresponding building pipes or pipe connections. This is because various trades are usually active at this time, such as floor fitters, drywallers, tilers, electricians, etc. Such assembly modules must therefore enable the later connection of a toilet body during this construction period without causing damage and, in addition, protect access to building connections, for example, to prevent unpleasant odors from escaping from the building's wastewater line or contaminants from entering such a wastewater line during the construction period. Furthermore, such assembly modules should enable the simplest and safest possible connection of the toilet body after the pre-wall and, in particular, the floor in a room have been erected. Such assembly modules only partially meet these requirements. For example, it is known to deliver assembly modules with covers that can be attached to the flush pipe connection and the drain pipe connection. While this can in principle prevent damage to the drain pipe connection and the flush pipe connection, as well as the ingress of contaminants into these connections and the escape of unpleasant odors are largely avoided. However, such cover hoods only inadequately ensure that the pre-wall can be easily completed in a way that ensures the most universal connection possible for any toilet bowl. It should be noted that toilet bowls with a wide variety of functions are available on the market today, for example with additional features such as a hygienic flush, odor extraction, or a drying fan. Different toilet bowls require different wall connections, and providing cover hoods on the flush pipe connection and drain pipe connection does not create sufficient space to later allow the direct connection of almost any toilet bowl to the pre-wall without the need for complex and difficult additional work, such as deliberately prying open the pre-wall. Furthermore, depending on the design of the cistern and toilet body, different types of wall connections are required, for example, an electrical connection to supply power to the toilet body, for example, to heat water for a shower facility, for an odor extraction system, or for a hairdryer, an electrical connection to supply power to an electric actuator plate, and/or a water connection provided in addition to the flush pipe, for example, for a shower facility. Furthermore, conventional installation modules do not offer any safety precautions to ensure that the respective wastewater outlet connection of the toilet body and the flush water supply connection of the toilet body are properly connected during a subsequent connection of a toilet body, even when providing pre-walls with a considerable depth. fluid-tight connection to the flush pipe connection or the drain pipe connection. In addition, during the typically long construction period, during which the mounting module is installed in a room before the pre-wall construction is completed, modifications to the mounting module can easily be made by unauthorized personnel or information about the installation requirements of the mounting module can be lost until the installing plumbing specialist finally installs a toilet body on the front of the pre-wall, which can lead to further errors in the installation of the toilet body. EP 3 258 020 A1 discloses an assembly module according to the preamble of claim 1. The assembly module comprises a two-part connection stem with a connection element and a closure element. In a construction-time position, the closure element is attached to the connection element. Starting from the construction-time position, the closure element can be detached from the connection element, while the connection element remains unchanged on a mounting frame of the assembly module, thereby establishing an operating position of the assembly module in which a flush pipe connection and a drain pipe connection are accessible from a front side of the module.

The present invention is therefore based on the object of providing an assembly module or a method for realizing a pre-wall in front of such an assembly module or a method for realizing a WC installation or a system with such an assembly module, which at least partially eliminates at least some of the problems and disadvantages of known assembly modules or methods or systems.

As a solution to the above-mentioned, the invention The invention proposes an assembly module with the features according to claim 1.

The assembly module is suitable for mounting a cistern, in particular behind a pre-wall, which is arranged on a front side of the assembly module extending along a vertical and a transverse line. The assembly module comprises a module frame, which extends with its module frame height along the vertical and with its module frame width along the transverse line. The assembly module further comprises a drain pipe and a cistern with a flush pipe, wherein in a construction-time position of the assembly module, which has a fixed The arrangement of the components of the assembly module relative to one another is defined, the cistern is attached to the module frame, and the flush pipe forms a flush pipe connection open at the front of the assembly module, and the drain pipe is attached to the module frame and forms a drain pipe connection open at the front of the assembly module. The assembly module according to the invention can have further features that are explained above in connection with generic assembly modules or methods.

According to the invention, the assembly module has a two-part connecting extension comprising a connecting element and a closing element. The connecting element and the closing element are preferably each manufactured separately from the module frame. The connecting element is preferably made of plastic, preferably as an injection-molded part. The closing element is preferably made of plastic, paper, or cardboard. In the assembly-time position of the assembly module, the closing element of the connecting extension is releasably attached to the module frame and the connecting element and closes the flush pipe connection and the drain pipe connection. In this case, the closure element has on its front side, ie with its projection, viewed from the front side in a direction perpendicular to the transverse and vertical, a transverse and a vertical extension, within which both the flush pipe connection and the drain pipe connection are arranged, wherein this front side with its corresponding transverse and vertical extension, within which both the flush pipe connection and the drain pipe connection are arranged, by at least 15 mm, in particular at least 30 mm, in particular between 15 mm and 100 mm, over the module frame, ie over the front side of the module frame. In this case, protrusion generally means a protrusion along a direction that is perpendicular to the vertical and the transverse. The closure element is preferably fastened directly to the connection element and in particular directly to the module frame. In one embodiment, the closure element is fastened to the connection element indirectly via the module frame. In one embodiment, the connection element and/or the closure element is fastened to the module frame indirectly via the drain pipe fastened to the module frame and/or via the flush pipe fastened to the module frame. For this purpose, the connection element preferably has a first connection element section which is inserted outside around the flush pipe connection for fastening the connection element to the flush pipe, and/or a second connection element section which is inserted outside around the drain pipe connection for fastening the connection element to the drain pipe. Alternatively or additionally, the closure element preferably has a first closure element section, which is inserted into the flush pipe connection for fastening the closure element to the flush pipe, and/or a second closure element section, which is inserted into the drain pipe connection for fastening the closure element to the drain pipe. The closure element is preferably fastened to the module frame exclusively indirectly via the flush pipe and/or the drain pipe. The connection element is preferably fastened to the module frame exclusively indirectly via the flush pipe and/or the drain pipe. In this case, a corresponding design of the closure element and module frame as well as the closure element and connection element is always provided such that the closure element starting from the construction position, it is detachable from both the module frame and the connection element and can therefore be separated and removed from both. By closing the flush pipe connection and the drain pipe connection, the closure element ensures that a clear cross-section through which the drain pipe connection and the flush pipe connection are accessible from the front of the assembly module in the construction position is significantly smaller, in particular at least 50% smaller, in particular at least 80% smaller, in particular at least 95% smaller, than the respective clear cross-section of the flush pipe connection and the drain pipe connection, which form the flush pipe connection and the drain pipe connection in a plane spanned by the transverse and vertical lines. Particularly preferably, the closure element closes at least the drain pipe cross-section in an odor-tight manner.

Starting from the construction-time position, the closure element is detachable from the connection element and the module frame to create an operating position of the assembly module. The operating position of the assembly module defines an arrangement of these components that differs from the arrangement of the components of the assembly module defined in the construction-time position. However, starting from the construction-time position in the operating position, the cistern is still attached to the module frame and the flush pipe still forms a flush pipe connection that is open at the front of the assembly module, and the drain pipe is still attached to the module frame and forms a drain pipe connection that is open at the front of the assembly module. Particularly preferably, a changed arrangement of the closure element relative to the other components of the assembly module is the only Difference between the construction-time position and the operating position. In one embodiment, the only difference between the operating position and the construction-time position is a change in the position of the closure element and the connection element relative to the other components of the assembly module. In the operating position, the connection element is fastened to the module frame, preferably unchanged from the construction-time position. In the operating position, the connection element protrudes with its front side beyond the module frame, i.e. beyond the front side of the module frame, in particular by at least 5 mm, in particular between 5 mm and 30 mm beyond the module frame, preferably unchanged from the construction-time position. The connection element forms a guide running in a direction that is perpendicular to the transverse and perpendicular to the vertical, which guide runs in front of the front side of the module frame with at least one guide section and, in particular, extends further behind the module frame with a further guide section that is directly connected to the first-mentioned guide section. Particularly preferably, starting from the operating position, the closure element can be placed on the front side of the connecting element in order to realize the construction time position, in particular without changing the position and fixing of the connecting element relative to the module frame, and can be releasably fixed relative to the connecting element, for example by directly fixing it to the connecting element and/or fixing it to the module frame, wherein particularly preferably the closure element with its front side, with which it has the said transverse and vertical extension, within which both the flush pipe connection and the drain pipe connection are arranged, in the construction time position protrude at least 5 mm, in particular at least 10 mm, beyond the front of the connecting element.

The assembly module according to the invention offers a number of advantages. By providing a two-part connection extension, special consideration can be given to the different circumstances and requirements during the construction period, during which the pre-wall is also being erected, and during the connection of a toilet to the assembly module after the construction period, i.e. after the pre-wall has been installed. By virtue of the fact that, in the construction position of the assembly module, the front of the closure element extends transversely and vertically over the flush pipe connection and the drain pipe connection, thus covering both of these when viewed from the front, in particular by forming a flat, closed front side of the closure element, and closing the pipe connections, damage to these pipe connections can be prevented on the one hand, and the ingress of contaminants into lines connected to these pipe connections can be prevented on the other. Since the closure element, with its front side, which covers the drain pipe connection and the flush pipe connection, as seen from the front, protrudes significantly beyond the module frame, in particular by at least 15 mm, in particular by at least 30 mm, in particular by at least 50 mm, in particular between 15 mm and 100 mm, in particular between 30 mm and 100 mm, the closure element also serves as a placeholder for an opening to be provided in the pre-wall when the pre-wall is installed on the front of the assembly module. This particularly favors the provision of a sufficiently large opening in the pre-wall, which allows for a universal connection of almost any toilet body with almost any functionalities. permitted. By the closure element specifying clear dimensions of the opening in the pre-wall and thus enabling, for example, a tiler to specifically provide the opening in the size of the closure element, i.e. the transverse and vertical extension of the closure element with its front side, it can be ensured that only such an opening is created in the pre-wall that is covered by almost every standard toilet body after its installation on the front of the pre-wall. By also providing a connection element which is detachably attached to the closure element in the construction position and which, in the operating position, provides a guide with a guide section in front of the front of the module frame, it is ensured, on the one hand, that the connection element is reliably fixed to the module frame in the construction position and does not get lost. On the other hand, it is ensured that in the operating position, in which a toilet body can preferably be connected to the assembly module, a guide is provided which simplifies the connection of the toilet body. The guide can, for example, comprise a fluid guide from at least one of the drain pipe connection and the flush pipe connection to the front of the module frame, whereby in the event of a faulty connection of a waste water connection line leading to a toilet body at the drain pipe connection and/or a faulty connection of a flush water connection line leading to a toilet body at the flush pipe connection, any leaking water is guided in front of the module frame so that it can be detected from the front of the pre-wall. The guide can, for example, also comprise a geometric guide, for example by providing a cavity or guiding side walls, which enable the targeted positioning of a connecting device, such as a hygiene flush supply hose or an electrical supply line or an electrical control device or other connection device that can be connected to a toilet body, or other components such as a projection set for the targeted vertical installation of a toilet body. By extending at least with a guide section in front of the module frame, the guide ensures sufficient guidance along the direction that is perpendicular to the transverse and vertical and/or enables sufficient storage space and the provision of sufficient guide sections to facilitate a toilet connection. Particularly preferably, the guide, with its guide section extending in front of the module frame, is arranged exclusively within a vertically and transversely extending extension area, which the said front side of the closure element, which protrudes at least 15 mm from the module frame, covers with its transverse and vertical extensions in the construction position. Particularly preferably, the entire extension of the connecting element in the operating position, with which the connecting element extends in front of the module frame, is arranged exclusively within a vertically and transversely extending extension area, which the said front side of the closure element covers in the construction position with its transverse and vertical extension. Particularly preferably, the connecting element is reversibly detachable from the module frame starting from the operating position, i.e., detachable from the module frame and subsequently reattached. A corresponding, reversibly detachable attachment can be effected, for example, by a latching and/or clamping. Particularly preferably, the module frame has two vertically extending support struts and several transversely extending extending transverse struts. Preferably, the drain pipe connection is arranged vertically between two of the transverse struts, wherein the drain pipe preferably overlaps with at least one, in particular both, of the transverse struts at its end forming the drain pipe connection in a direction perpendicular to the vertical and transverse directions. Preferably, the drain pipe is fastened to at least one of the two transverse struts by means of a fastening device, such as a clamp, at its end forming the drain pipe connection. Particularly preferably, the transverse struts are vertically spaced from one another by at least 11 cm. Particularly preferably, starting from the operating position, the connecting element is detachable from the module frame, releasing a free space on both transverse sides of the drain pipe connection, previously covered by the connecting element as seen from the front, wherein the free space on each of the transverse sides of the end of the drain pipe forming the drain pipe connection extends in the transverse direction over at least 5 cm, in particular at least 10 cm, starting from the respective transverse end of the end of the drain pipe, in particular extends vertically continuously between the two transverse struts, in particular in the transverse direction continuously up to the support strut adjacent to the respective transverse end of the end of the drain pipe. By releasing this free space, the connection of the drain pipe of the assembly module to a building-side wastewater line is particularly simplified, since after dismantling the connection element from the module frame, the free space allows easy handling of the drain pipe, in particular also dismantling and/or moving of the drain pipe from the module frame, whereby the drain pipe can be easily inserted into a Wastewater pipe connection of the building's wastewater pipe can be plugged into or connected to it.

In one embodiment, the vertical and horizontal extension of the element at its front side, which protrudes at least 15 mm beyond the module frame and within which both the flush pipe connection and the drain pipe connection are arranged, is each delimited by an outer side of the closure element running around the flush pipe connection and the drain pipe connection. The outer side preferably runs continuously around the flush pipe connection and the drain pipe connection, in particular continuously around it. The outer side preferably runs, in particular continuously, from the aforementioned front side of the closure element to the front side of the connection element or to the front side of the module frame along a direction that is perpendicular to the vertical and the transverse, wherein it runs around the flush pipe connection and the drain pipe connection over its course in this direction. Preferably, the outer side of the closure element includes the same transverse and vertical extension throughout its extension in this direction from the front side of the closure element to the front side of the connecting element or to the module frame, so that a section through the outer side has the same areal extension in every plane spanned by the transverse and vertical within this area. By providing such a circumferential outer side of the closure element, the closure element can serve as a particularly good orientation for the provision of an opening in the pre-wall, in particular during the application of a tiled covering of the pre-wall. Particularly preferably, the outer side has their opposite absolute transverse ends have an extension of at least 15 cm, in particular at least 20 cm, and between their opposite absolute vertical ends have an extension of at least 20 cm, in particular at least 25 cm. Particularly preferably, the circumferential outer side of the closure element encloses a transverse and vertical area of at least 300 cm ² , in particular at least 400 cm ² . As a result, a particularly advantageous, large opening in the pre-wall, which can still be closed by a standard toilet body, can be kept free by the closure element.

In one embodiment, the connecting element in the operating position, and in particular also in the construction position, has a fluid guide from the flush pipe connection and/or the drain pipe connection to in front of the module frame for draining leaking water escaping from the flush pipe connection and/or the drain pipe connection. The guide formed by the connecting element thus comprises the fluid guide or is designed as the fluid guide. As explained above, this can ensure particularly reliable guidance that leaking water escaping from the flush pipe connection and/or the drain pipe connection is guided through the fluid guide in front of the module frame, particularly preferably in front of the prefabricated wall, thus preventing undetected moisture from forming behind the prefabricated wall, which could, for example, lead to building damage, such as mold formation. The fluid guide preferably extends with a first guide section in front of the front of the module frame and with a second guide section starting from the first guide section to behind the flush pipe connection or the drain pipe connection, wherein particularly Preferably, the fluid guide and in particular the said first and second fluid guide sections each have a first part which is assigned to the flush pipe connection and runs below the flush pipe connection but above the drain pipe connection, and a second part which is assigned to the drain pipe connection and runs below the drain pipe connection, so that leakage water emerging from the pipe connection assigned to the respective part can be reliably drained away via the two parts. Particularly preferably, the connecting element has a first pipe socket with which it is connected to the flush pipe connection in a fluid-conducting manner in the operating position, and a second pipe socket with which it is connected to the drain pipe connection in a fluid-conducting manner in the operating position. The first and second pipe sockets thus at least partially form the fluid guide of the connecting element and each have a first section which extends in front of the module frame and a second section which, starting from the first module frame, runs behind the respective connection. The provision of a pipe socket as part of the fluid guide has proven particularly advantageous for the particularly reliable routing of leakage water from the respective pipe connection to the front of the module frame. Particularly preferably, the first pipe socket is arranged outside the flush pipe connection and/or the second pipe socket is arranged outside the drain pipe connection.

In one embodiment, the closure element comprises a first and a second cylindrical closure section, wherein in the construction time position the first cylindrical closure section closes the flushing pipe connection and the second cylindrical closure section closes the Closes the drain pipe connection. In one embodiment, in the construction-time position, the first cylindrical closure section is arranged within the first pipe socket formed by the connection element and is connected via said first pipe socket to the flush pipe connection, and the second cylindrical closure section is arranged within the second pipe socket formed by the connection element and is connected via said second pipe socket to the drain pipe connection. In one embodiment, in the construction-time position, the first cylindrical closure section is arranged in the flush pipe connection and the second cylindrical closure section is arranged in the drain pipe connection.

According to the invention, the connection element has a cavity which has a front side and which is open at its front side and, in the operating position, is accessible from the front side, in particular from the front side of the mounting module. The cavity has a transverse and a vertical extension, wherein the flush pipe connection and the drain pipe connection are arranged within the transverse and vertical extensions of the cavity. The cavity comprises at least one partial cavity which is provided within the transverse and vertical extensions of the cavity and which is defined by a respective partial cavity wall which delimits the partial cavity transversely and/or vertically and extends with its partial cavity wall height perpendicular to the transverse and vertical. The cavity has an extension in a direction perpendicular to the transverse and perpendicular to the vertical, which is preferably at least 5 mm, in particular at least 10 mm long. Accordingly, the cavity is suitable for accommodating for connecting a toilet body necessary elements, such as supply lines, connection devices such as control devices, operating devices, transformers or the like, other components, etc., since sufficient space is provided by the depth of the cavity, i.e. its extension in a direction which is perpendicular to the vertical and the transverse, In one embodiment, the connection element has a first and a second pipe socket which are enclosed by the cavity, wherein at least a section of the wall of the respective pipe socket represents a partial cavity wall and the clear cross section of the respective pipe socket represents a partial cavity. Generally speaking, the cavity is delimited by a wall, preferably delimited by a transversely and vertically circumferential wall, wherein the wall extends with its wall height perpendicular to the transverse and perpendicular to the vertical and preferably defines the extension of the cavity in this direction via its wall height. Particularly preferably, the wall has a wall height averaged over its circumferential length of at least 5 mm, in particular at least 10 mm, wherein the wall with its circumferential length runs around a transversely and vertically extending region and thereby encloses a vertically and transversely extending area, which is preferably at least 300 cm ² , in particular at least 400 cm ² . Particularly preferably, the wall runs on both transverse sides of the flush pipe connection and the drain pipe connection with a section each vertically between the flush pipe connection and the drain pipe connection and is spaced with these sections transversely from the flush pipe connection and the drain pipe connection, in particular by at least 3 cm each, in particular on at least one transverse side by at least 5 cm, in particular at least 8 cm, in particular on both transverse sides by at least 5 cm each, in particular at least 8 cm. The cavity is thus preferably delimited by a wall having a wall section that is spaced apart in the transverse direction from the flush pipe connection and the drain pipe connection. As a result, the cavity can provide a particularly suitable receiving space for a connection device for the toilet body. In general, the cavity is preferably arranged with its entire transverse and vertical extent completely within a vertically and transversely extending extension region that the front side of the closure element covers with its transverse and vertical extent in the construction position, this being the said front side of the closure element, which protrudes by at least 15 mm beyond the module frame in the construction position. This ensures that the closure element provides a placeholder in the construction position and thus during construction, in particular during construction of the pre-wall, which ensures access to the cavity after the pre-wall has been realized. In general, the assembly module particularly preferably has a cavity cover which is designed for the reversible closing of at least part of the front side of the cavity starting from the operating position. For this purpose, the cavity cover particularly preferably has mechanical closure means which correspond to mechanical closure means which are provided on the cavity, in particular on the wall of the cavity or on at least one partial cavity wall. By providing a cavity cover which can reversibly close part of the front side of the cavity, in particular the front side of a partial cavity delimited by a partial cavity wall, a particularly good chambering of a connection device or other device suitable for a toilet used component, in particular an electronic component, must be guaranteed, which can protect this component or the connection device particularly advantageously when a toilet body is connected to the mounting module, which typically remains unchanged over a very long period of many years. In general, the cavity preferably has a rear wall on its rear side opposite the front side which is open in the operating position, which closes at least 50%, in particular more than 70%, of the rear of the cavity. In this case, the rear wall does not in any case close the clear cross-sections of the flush pipe connection and the drain pipe connection, which are preferably located within the cavity. By providing a rear wall which at least partially closes the rear of the cavity, the cavity can ensure particularly targeted accommodation of the connection device or other components and, in particular, also better protection of the same.

In one embodiment, the connecting element and the closure element are configured to correspond to one another in such a way that, in the construction position, their transverse and vertical ends merge flush with one another, at least in sections. Particularly preferably, the connecting element does not protrude transversely or vertically beyond the closure element. This flush transition can particularly facilitate the use of the assembly module, and in particular, the construction of a pre-wall in front of the assembly module can be particularly simplified.

In one embodiment, the mounting module has a supply hose that runs from an electrical connection and/or a water connection of the cistern to the connecting element and opens into a region of the connecting element which lies within a vertically and transversely extending extension region which the front side of the closure element covers in the construction position with its transverse and vertical extension, wherein the focus is on the said front side which protrudes by at least 15 mm beyond the module frame. Preferably, the region into which the supply hose opens lies, at least in sections, transversely outside the flush pipe connection and the drain pipe connection. This can enable particularly good accessibility to this area, even after a toilet body has been connected. Particularly preferably, the region extends transversely between 60 mm and 150 mm, in particular between 60 mm and 120 mm, beyond the vertical line running centrally through the flush pipe connection and the drain pipe connection. Particularly preferably, the supply hose opens into the cavity of the connecting element. Particularly preferably, the cavity has the aforementioned rear wall, wherein the rear wall has an opening into which the supply hose opens. In general, the rear wall preferably has predetermined breaking sections that can be broken open from the front under pressure, thereby releasing an opening defined by the predetermined breaking sections. This allows an installer, for example an electrician or plumber, to provide an opening in the rear wall of the cavity at a location suitable for connecting the respective toilet body, through which opening a connecting device to the toilet body can be guided or through which a component extending away from the toilet body at its rear can protrude.

According to the invention, the cavity comprises at least one Partial cavity, in particular a plurality of partial cavities. According to the invention, at least one, in particular a plurality of the partial cavities are arranged with their vertical and transverse extensions completely outside the vertical and transverse extension of the flush pipe connection and the drain pipe connection. The partial cavity is provided within the cavity and is delimited at least in sections by a partial cavity wall from regions of the cavity that are provided horizontally and/or vertically adjacent to the partial cavity. In one embodiment, the cavity comprises a partial cavity that is circumferentially enclosed by a partial cavity wall, wherein preferably a section of the partial cavity wall is provided by the wall of the cavity, whereas the remainder of the partial cavity wall runs within the cavity. Particularly preferably, a partial cavity wall is provided in the cavity, which delimits two adjacent partial cavities of the cavity from one another. Particularly preferably, the cavity has at least one partial cavity which, with respect to the vertical and with respect to the transversal, lies outside the flush pipe connection and outside the drain pipe connection, wherein in one embodiment, the connection element has a first and second pipe socket as explained above, and the pipe socket wall of the first and second pipe socket each forms at least a section of the partial cavity wall. Particularly preferably, the supply hose explained above opens into one of the partial cavities. Preferably, the rear wall of the cavity explained above extends at least partially, in particular completely, over the rear side of the partial cavity, wherein the rear wall has an opening within the partial cavity into which the supply hose opens. Particularly preferably, this opening is located vertically below of the flush pipe connection and vertically above the drain pipe connection, wherein this opening preferably has a first vertical distance from the flush pipe connection and a second vertical distance from the drain pipe connection, wherein the second distance is preferably at least twice, in particular at least three times, in particular at least five times the first distance. Particularly preferably, the opening is arranged in a transverse region which is transversely spaced less than 2 cm from a vertical axis which runs through the center point of the flush pipe connection and through the center point of the drain pipe connection. Particularly preferably, the transverse extent of the opening is limited to a transverse region which extends up to a maximum of 10 cm, in particular a maximum of 8 cm, in particular a maximum of 5 cm transversely away from the said vertical axis. Particularly preferably, the connection element has the first pipe socket explained above, wherein the opening is vertically spaced less than 1 cm from the pipe socket. Particularly preferably, the assembly module comprises a water line and/or an electrical line, wherein the water line and/or the electrical line are arranged in the supply hose in the operating position and each extend from a connection of the cistern through the supply hose into the cavity, in particular into the said partial cavity.

This reference information contains a unique reference to specific assembly information stored in the information storage database. In general, the invention also relates to a system for providing information about a sanitary article having a QR code provided on the sanitary article, even independently of the assembly module according to the invention. By providing an intermediate database and an information storage database, the QR code can contain dynamically changeable information that can be changed easily and can have a high level of detail without the QR code having to be designed in a more complex manner. It should be noted that a complicated design of a QR code, through which a larger and thus more complex amount of information can be contained in a QR code, results in a more error-prone readability of the QR code. The inventors have recognized that by realizing a sanitary article, in particular an assembly module, with a QR code and providing an intermediate database and an information storage database, in which the aforementioned reference information or information on the sanitary article is contained, a structure is created that allows a manufacturer of the sanitary article to store changeable, in particular correctable, information on the sanitary article in the information storage database at different times, while has control over the reference via the intermediate database with which the QR code is linked to the corresponding information on the sanitary article. Particularly preferably, the QR code contains at least two different pieces of information, each of the pieces of information containing a different reference to another piece of reference information stored in the intermediate database, which contains a unique reference to a different piece of assembly information stored in the information storage database. Additionally or furthermore, the reference information stored in the intermediate database can have a multiple coding which, depending on a coding parameter additionally transmitted with the transmission of the reference transmitted in the QR code, refers to assembly information stored in the information storage database and associated with the respective coding parameter. The assembly information is only one example of any other information about the sanitary article. In the second alternative, which can be provided in addition to or as an alternative to the first alternative, reference information with a multiple coding is stored in the intermediate database, to which the QR code uniquely refers. When reading the QR code, depending on the software used to read the QR code or to send the reference, a coding parameter can be transmitted that selects the multiple coding, so that through the correspondence between multiple coding and coding parameter, the reference information can be referenced to a specific piece of information in the information storage database, depending on the coding parameter transmitted by the software with which the QR code was read and transmitted. The two alternatives mentioned offer the particular advantage that by providing a single QR code Different people can receive different information. For example, specialist personnel associated with the manufacturer of the mounting module can receive information about the mounting module that is not available to an installer, such as the batch number, serial number, etc. In the event of maintenance, the relevant specialist personnel can thus receive additional information about the mounting module if necessary.

In the construction-time position, the first cylindrical closure section 75 is arranged in the first pipe socket 65 and the second cylindrical closure section is arranged in the second pipe socket 68 to close the flush pipe connection 51 and the drain pipe connection 81. The assembly module 1 further has two fastening rods 10 designed as threaded rods and a storage cavity closure 710. The closure element 7 has a storage cavity 71 in which the fastening rods 10 are stored in the construction-time position, while they extend with their rod extension along the vertical Z. The storage cavity closure 710 can be detachably fastened to the closure element 7. The connecting element 6 has a cavity enclosed by a transversely and vertically circumferential wall 60, which is open at its front side and partially closed at its rear side by a rear wall. The cavity comprises a first partial cavity 64 and a second partial cavity 63. The first partial cavity 64 is delimited from the second partial cavity 63 by a section of the partial cavity wall 61. Both partial cavities 63, 64 are each transversely and vertically circumferentially enclosed by a partial cavity wall 61, wherein the wall of the cavity forms a section of the respective partial cavity wall 61, and the pipe wall of the first pipe socket 65 forms a section of the partial cavity wall 61 surrounding the first partial cavity 64, and the second pipe socket forms a section of the partial cavity wall 61 surrounding the second partial cavity 63. and a further section, which the partial cavity walls of the first and second partial cavities 63, 64 jointly form, separates the partial cavities 63, 64 from each other. The supply hose 3 opens into the first partial cavity 64 at an opening 640. The second partial cavity is separated from the first partial cavity 64 by the partial cavity wall 61 and by a Figure 3c shown partial cavity cover 630 can be reversibly closed. The second partial cavity 63 is particularly well suited for accommodating an electronic component that can be connected to a toilet body to be connected to the mounting module 1 and/or the cistern 2. Through a feedthrough provided in the section of the partial cavity wall 61 separating the partial cavities 63, 64 from one another, an electrical line, via which a low voltage can be transmitted, can pass from the second partial cavity 63 and thus from an electronic device provided in the second partial cavity 63 into the first partial cavity 64 and from there via the opening 640 into the supply hose 3 and via this to the cistern 2. In addition, a further electrical line can be fed to the toilet body through a passage provided in this partial cavity wall 61 and/or in the partial cavity cover 630, for example to supply power to a hot water heater, a hair dryer and/or a communication module (e.g. WLAN or Bluetooth module) that can be provided in the toilet body. By providing the cavity, in particular the aforementioned partial cavity 64, in particular the aforementioned second partial cavity 63, it can also be ensured, for example, that the cistern 2 does not have to be connected directly to a building-side supply network cable that has a correspondingly high voltage, but that the cistern is indirectly connected to the power supply network via the The electrical device arranged in the cavity can be connected, which can be particularly advantageous for safety reasons, especially with regard to the open water surface provided in the cistern. Figure 1 Furthermore, a connecting sleeve 9 for connecting the drain pipe 8 to a sewage pipe of a building is shown as an example.
