Description

The invention relates to a drain system according to the preamble of claim 1 and a method for installing a drain system in a room floor. Generic drainage systems are used to conduct water from the surface of a room floor into a drain pipe system. Such a drain system is usually installed in the room floor, that is to say integrated into the room floor, with a slope being provided in the room floor such that water on the room floor is conducted to the drain system. Generic drain systems have a drain pot that has a connector for connecting to a drain pipe of a drain pipe system. When installing a generic drain system in a room, the drain pot is first connected to a drain pipe so that its inlet opening points upwards, the drain pot and the drain pipe being placed on a floor of the room. Subsequently, when installing a generic drain system, screed is laid on the floor, which then finally determines the position of the drain pipe and the drain pot. The drain pot is then sealed off from the screed by gluing a sealing sleeve provided on the drain pot to the screed. Generic drainage systems have also a gutter with a nozzle that is used in the installation of the drain system in the room in the inlet opening of the drain pot, and an odor trap (also shown as a "siphon"), which is inserted into the gutter or in the nozzle on the gutter . The odor trap ensures that unpleasant smells from the drain pipe system do not enter the room through the nozzle. In addition, if possible, the nozzle is sealed off from the drain pot, so that an odor barrier is also ensured between the nozzle and drain pot.

When installing a generic drain system, the drain system is integrated into the floor of the room, which includes a floor covering, such as tiles. The drainage channel of the drainage system must be integrated into the level of the floor covering both optically and functionally. Depending on the application, elongated, such as, for example, rectangular or oval, and also uniformly dimensioned, for example, circular or square, drainage channels are known in the prior art, the latter often being referred to as "point sequences". The variants mentioned can, for example, have any or no symmetry, for example have a polygonal outline in the horizontal. The above-mentioned integration of the drainage channel has proven difficult in the case of generic drainage systems. Because with generic drain systems, the position of the drain pot in the room is fixed before the floor covering is laid. A variation of the position of the gutter depending on the technical and visual requirements when laying the flooring is therefore only possible to a very limited extent. Especially when installing a gutter on a room boundary element, such as a wall, reinforced This problem arises because, for example, depending on the thickness of the wall tile provided, the drainage channel must be at a corresponding distance from the space-limiting element.

In the prior art, the difficulties described for generic drainage systems were tackled in various ways. For example, in DE 20 2014 007 391 U1 discloses a drain system in which a receiving tube with a circular cross section is provided for insertion into the drain pan, whereas the connection piece fastened to the drain channel has a flattened cross section, so that it can be inserted eccentrically to the receiving tube in the receiving tube. Depending on the orientation of the gutter to the receiving tube, a certain variation of the relative position of the gutter to the drain pot can be made possible due to the eccentric arrangement of the nozzle in the receiving tube. The connector is sealed relative to the receiving tube by providing a fixing ring which receives the flattened cross section of the connector and has such a horizontal extension that it comes to rest on the receiving tube at the top of the receiving tube when the connector is placed on it, and thereby the gap between the receiving tube and spigot covered to a significant extent. Another way was in EP 1 674 629 B1 and DE 10 2005 036 576 A1 followed. In this document, a drain system is disclosed in which a double pipe system is provided between the drain pot and the nozzle attached to the drain gutter. The double pipe system has two concentrically arranged pipes. The outer tube is sealed to the drain pan, the inner tube is sealed to the drain gutter nozzle. Outer and inner tubes each have a horizontally extending flange, the two flanges of the two tubes being parallel to one another over a considerable horizontal section run and a seal between the two flanges is provided so that the inner tube is horizontally displaceable relative to the outer tube, while the flange of the inner tube slides sealingly along the seal which is attached to the flange of the outer tube. The generic drain systems described have various disadvantages. With the eccentric arrangement of the nozzle in the receiving pipe, only a very limited variation of the position of the drainage channel relative to the drain pot is possible, and moreover, the odor barrier between the receiving pipe and the nozzle is poor because there is no adequate sealing between these two components. The provision of a pipe system with parallel flanges of the two pipes, as explained, does enable a sufficient odor barrier and a sufficient horizontal displacement of the drainage channel relative to the drain pan. However, the production of such a drain system is expensive due to the large number of components used, and due to the large number of seals used, such a drain system is relatively prone to errors.

The present invention has for its object to provide a drain system that at least partially eliminates the problems described above that occur when installing generic drain systems and / or the disadvantages of generic drain systems.

As a solution to at least one of the objects on which the present invention is based, the invention proposes an execution system with the features of claim 1. The drain system includes a drain pot with an inlet opening. The drain pan is intended to be placed on a floor of a room and connected to a drain pipe in such a way that its inlet opening in the room points upwards. The execution system according to the invention further comprises a Drainage channel with a socket for insertion in the inlet opening of the drain pan. In one embodiment, the gutter is made integral with the nozzle as a one-piece component. In one embodiment, the drainage channel and connecting piece are each produced as a separate component and then connected to one another. The connection between the gutter and nozzle is preferably such that these two parts are non-detachably connected to each other, that is, when used as intended, they cannot be detached from each other but only with considerable mechanical and / or chemical effort. The cross-section of the socket is designed so that it corresponds to the inlet opening of the drain pot so that the drainage channel with the nozzle arranged on it can be placed from above onto the upward-pointing inlet opening of the drain pan, while the socket has at least one vertical section through the inlet opening in the drain pot enters and is placed in the drain pot. The drainage channel can be designed as required, for example elongated in the horizontal or as a uniformly dimensioned point drain. The invention has proven to be particularly advantageous for elongated gutters, since the problem of positioning the gutter can be particularly virulent here.

The drainage system according to the invention further comprises a seal for the extensive, in particular circumferentially closed sealing of the connection piece against the drain pot. The seal can thus preferably be mounted between an inner wall of the drain pot and an outer wall of the connecting piece in such a way that the outside of the connecting piece is sealed around the connecting piece with respect to the drain pot and is therefore sealed without interruption. In one embodiment, the nozzle is designed in the manner of a cylinder, the seal being designed in the manner of a sealing ring which can be pushed sealingly onto the outside of the cylinder and, when the cylinder is provided with the seal in the drain pot, seals the cylinder against the drain pot in a closed manner. In one embodiment, the connecting piece can comprise a plurality of partial connecting pieces, each of which can be designed, for example, in the manner of a cylinder. In this embodiment, the seal is designed in such a way that it can be arranged around all the partial connections for sealing the outside of all partial connections against the drain pot.

The drain system according to the invention further comprises an odor trap which can be used in the nozzle to prevent odors from escaping from the drain pipe system through the nozzle into the outside. The odor trap can be implemented in a conventional manner, for example in the manner of a siphon or as an elastic plastic hose that opens to allow waste water to pass through and then closes automatically. The drain system according to the invention further comprises a sealing sleeve, which is arranged sealingly on the drain pot or can be arranged in a sealing manner and by means of which the drain pot can be sealed against a screed which is laid around the drain pot by gluing the sealing sleeve onto the screed. The execution system according to the invention thus comprises several individual components. These components are designed to correspond to each other in such a way that they can be aligned or arranged with respect to one another for an assembly arrangement of the drain system, in which the drain system fulfills its intended function, that is to say the removal of water that is located on a room floor into a drain pipe Drain pipe system. In this assembly arrangement of the drain system, the nozzle is arranged at least with a vertical section horizontally within the drain pot. The seal is so relative to that in the mounting arrangement Stub and arranged relative to the drain pan that it extends horizontally circumferentially, in particular circumferentially closed, around the neck and seals the neck circumferentially, in particular circumferentially closed, against the drain pan. The odor trap is arranged in the mounting arrangement in the nozzle. It is arranged horizontally completely within the socket and vertically at least in sections within the socket and in particular vertically at least in sections within the drain pot. Furthermore, in the assembly arrangement, the sealing sleeve is sealingly connected to the drain pot. The sealing sleeve preferably extends with all of its two-dimensional extension directions beyond at least 5 cm, in particular at least 10 cm, beyond the drain pot, so that the sealing sleeve provides a sufficiently large, closed sealing surface around the drain pot for gluing with a screed. According to the socket, seal and drain pan are designed so that they correspond to each other that in the mounting arrangement, the socket and the seal are together horizontally displaceable relative to the drain pan. It must be taken into account here that in the assembly arrangement the seal continuously provides a seal for the connector relative to the drain pot, that is to say during a horizontal displacement of the connector together with the seal relative to the drain pot. According to the invention, the seal has a first contact section, by means of which it presses against the socket in the mounting arrangement with a horizontal contact force, as well as a second contact section, which is guided in the mounting arrangement in a receiving groove of the drain pot that runs horizontally around the socket, this second Contact portion of the seal in this provided by the drain pot, that is integrated in the drain pot sealingly connected to the drain pot, which is preferably ensured, in particular is ensured only by the fact that the second contact section presses against the drain pot with a vertical contact force, the first and the second contact section of the seal being integrally connected to one another or the seal having a first sealing ring which provides the first contact section and a second sealing ring, which provides the second contact section, these two sealing rings being connected to one another in an integral or form-fitting manner by an intermediate element. The seal thus lies at the same time in a sealing manner on the connecting piece and in a sealing manner on the drain pot, a circumferentially closed seal for the connecting piece or drain pot being provided in each case in particular by means of the first and second contact sections. The seal with respect to the socket is ensured by the fact that the seal with its first contact section presses horizontally against the socket, whereas the seal with respect to the drain pot is preferably ensured by the fact that the seal with its second contact section presses vertically against the drain pot. It is of course possible, depending on the geometric configuration of the components and depending on the movement of the components to one another, that in some embodiments the seal also exerts a certain vertical pressing force on the connecting piece with its first contact section and also a certain horizontal pressing force against it with its second contact section exercises the drain pan. For the function of the drain system according to the invention, it is essential that the receiving groove runs around the connection piece, in particular runs closed, and runs horizontally. The receiving groove provides at least one wall running along the horizontal, which ensures an abutment surface of the drain pot on which the seal with its second abutment section is always guided, in particular can always be in contact with the vertical abutment force when the connection piece coexists with the Seal is located horizontally in different positions relative to the drain pan. In the case of a design of the connecting piece such that the connecting piece has a plurality of partial connecting pieces arranged horizontally next to one another, the seal is preferably designed in such a way that in the assembly arrangement with its first contact section, the entirety of the partial connecting pieces is closed horizontally and circumferentially encloses, while its second contact section is arranged in the receiving groove and is sealingly connected to the drain pot. The partial nozzles can be spaced horizontally from one another, for example, the seal also running between the partial nozzles and sealing the partial nozzles against one another; in another embodiment, the partial nozzles can have at least one common outer wall, by means of which they are inherently connected to one another and thus also sealed to one another. According to the invention, the seal rests with its first contact section with the horizontal contact force against the connector, the connector being vertically displaceable relative to the seal while maintaining the seal between the seal and connector. According to the invention, the seal is fixed in the mounting arrangement due to its arrangement in the receiving groove with its vertical position relative to the drain pan, whereas the socket can be displaced vertically relative to the seal and thus relative to the drain pan while maintaining the seal of the socket relative to the drain pan by means of the seal .

The drain system according to the invention has a number of advantages compared to drain systems of the generic type. On the one hand, the drain system can be produced from a small number of simply constructed components and is therefore inexpensive. On the other hand, the drainage system ensures a reliable seal between the nozzle and the drain pot thanks to the targeted, sealing contact of the seal on the drain pan and the nozzle. In addition, due to the arrangement of the seal in the horizontally extending receiving groove, a considerable displaceability of the connection piece relative to the drain pot along the horizontal plane is made possible. About the design of the receiving groove, in particular about the horizontal extent of the receiving groove, and about the Adjustment of the geometric dimensions of the nozzle and drain pot allows the extent of the displaceability to be set in a targeted manner when the drain system is implemented. Furthermore, with the drain system according to the invention, simple assembly is also ensured, since the seal can be arranged in advance in the receiving groove of the drain pan, after which, when the drain system is installed in a room floor, the connecting piece can be inserted vertically into the seal from above. The guidance of the seal within the receiving groove ensures such vertical support of the seal that even when a considerable vertical force is exerted when the connector is inserted, there is no deformation of the seal which impairs the function of the seal. The drain system according to the invention thus enables a very simple and therefore less error-prone installation of the drain system in a room floor.

In the drainage system according to the invention, the seal has a first contact section with which it presses against the connecting piece, and a second contact section with which it lies sealingly against the drain pot within the receiving groove, for which purpose it preferably presses against the drain pot. In one embodiment, the first and the second contact section of the seal are connected to one another in one piece, for example the first and second contact sections can be provided by a single sealing ring. This enables a particularly simple construction and a particularly simple and inexpensive manufacture of the drain system according to the invention. In another embodiment, the seal has a first sealing ring, which provides the first contact section, and a second sealing ring, which provides the second contact section, these two sealing rings being connected to one another in an integral or form-fitting manner via an intermediate element, the Intermediate element can be particularly preferably torsionally stiff, in particular torsionally stiff than the sealing rings.

In one embodiment, the receiving groove is formed by a vertically upper, horizontally circumferential, in particular closed, circumferential web and by a vertically lower, horizontally circumferential, in particular closed, circumferential web. Both webs are covered by the drain pan. At least one of the webs is designed as a separate press ring and, in the assembly arrangement of the drain system according to the invention, presses the seal vertically on the other of the two webs to provide the vertical contact force with which the second contact section of the seal presses against the drain pot inside the receiving groove to ensure the sealing Connection between drain pan and seal. One of the two webs, in particular the upper web, is particularly preferably integrated in the wall of the drain pan, whereas the other of the two webs, in particular the lower web, is designed as a press ring. The one web is then produced integrally with a section of the wall delimiting the drain pot. The other web is produced as a separate press ring, that is to say as a component separate from the wall, and is inserted into the wall to achieve the assembly arrangement. By pressing the seal with respect to the web integrated in the wall, one can in a particularly reliable manner Sealing of the nozzle relative to the drain pot to ensure the odor barrier can be provided. Particularly preferably, locking projections are provided on the wall of the drain pot, with which the web designed as a press ring can be locked in order to achieve the assembly arrangement. In general, "wall" is used to denote a vertical housing section of the drain pot, which surrounds and thus delimits an interior of the drain pot, in which a vertical section of the nozzle is arranged in the mounting arrangement. In the exemplary embodiments described, in which at least one of the webs is designed as a separate press ring, a particularly simple installation of the drain system according to the invention is made possible. Because the seal can be aligned relative to the drain pan, after which the receiving groove is only made by inserting the press ring. When the press ring is inserted, such a pressing force is exerted on the seal that a sufficient vertical contact force for sealing the seal relative to the drain pot is ensured.

In one embodiment, the drain pot comprises a base body and a cover, which are each produced as separate components and are subsequently connected to one another, the base body having a connection piece for a drain pipe and the cover having the receiving groove for the seal. In general, the drain pot can be made particularly preferably from stainless steel or from plastic. The production of the drain pot from two separate components, namely the base body and cover, which are particularly preferably each made of plastic, can be particularly simplified to implement the receiving groove and the sealingly pressed arrangement of the seal in the receiving groove. Because the lid is for the realization of the receiving groove and / or for the insertion of the Seal in the groove easily accessible from two sides. The lid preferably also has the inlet opening of the drain pot. The base body and cover are connected to one another in a closed, circumferentially sealing manner, in particular in a non-detachable manner, so that they cannot be separated from one another when the drain system is used as intended. In the present case, "sealing" generally means an at least watertight, in particular odor-tight seal, preferably a seal according to the test according to DIN EN1253, part 1, as of March 2015. The base body and cover are particularly preferably welded together to produce the drain pan, in particular these two components are made of plastic and are mirror-welded together. In an alternative embodiment according to the invention, the connection is detachable and sealing, for example via a clip connection, with a molded seal being provided between the cover and the base body.

In one embodiment, the seal has a closed circumferential core, the two contact sections each being provided by a closed circumferential elastic plastic ring which is circumferentially connected to the core. In one embodiment, the two contact sections are each provided by one of two separately provided plastic rings each connected to the core. In one embodiment, the two contact sections are jointly provided by a single, one-piece plastic ring which is connected to the core. Such a one-piece plastic ring can, for example, be integrally produced as a plastic ring in a single production step, in one embodiment, such a one-piece plastic ring that provides both contact sections is over two process steps manufactured, two separate plastic rings being produced in a first process step and the two separate plastic rings being connected to one another in a second process step to form a single, one-piece plastic ring. Both the core and the at least one elastic plastic ring are arranged in a closed circumferential manner in the assembly arrangement around the connecting piece, with a connection being provided between the core and at least one plastic ring such that the ensemble consisting of the soul and plastic ring runs along the entire circumference around the connecting piece each position is firmly interconnected. By designing the seal as a core and comprising at least one plastic ring, a seal with a high functionality for the drain system according to the invention can be provided in a cost-effective manner. This is because the soul can be used to influence the geometric shape and stability of the seal in a targeted manner, while the at least one plastic ring can be used to influence an embodiment of the seal that is advantageous with regard to a seal. In one embodiment, the core is made from a more rigid plastic than the plastic ring or from metal. In one embodiment, the plastic ring is made of an elastic material, whereas the core is made of a plastic material. In one embodiment, the core is made from a material that has a shear stiffness that is at least twice the shear stiffness of the material from which the at least one plastic ring is made. In one embodiment, the seal has a plastic ring which is designed in the manner of a bellows, the plastic ring having an opening for receiving the connecting piece, and in this embodiment the seal further has a soul designed in the manner of a circular ring which forms the bellows supported vertically, the bellows being supported vertically on the soul. Particularly preferably, the core is always guided in the mounting groove in the mounting arrangement, so that the core itself is supported vertically by the mounting groove and can thus always ensure adequate support of the bellows. Thanks to the bellows-like design of the plastic ring, a horizontal displaceability of the nozzle relative to the drain pot is guaranteed, while the plastic ring always ensures a seal between the nozzle and drain pot, with horizontal movement of the nozzle relative to the drain pot at least sections of the hawk bellows together with the nozzle relative to the drain pot be moved so that a joint movement of the nozzle with the seal takes place relative to the drain pot. If the seal is designed as a bellows, the seal between the second contact section and the drain pot can be made, for example, by gluing and in particular additionally by a vertical contact force. Very generally, in one embodiment, the seal, nozzle and drain pot are designed to correspond to one another such that when the nozzle moves in the mounting arrangement relative to the drain pot, the seal as a whole is moved together with the nozzle relative to the drain pot. In one embodiment, the at least one plastic ring and the core are integrally connected to one another circumferentially around the connecting piece. In one embodiment, the at least one plastic ring and the core are connected to one another in a form-fitting manner around the connecting piece. For example, recesses can be provided in one of the two components, plastic ring or core, while in the other of the two components (plastic ring or core), projections corresponding to the recesses can be provided, the corresponding recesses and projections being provided in the assembly arrangement Interlock gasket. The depressions and projections are particularly preferably formed with an extension in the vertical. For example, a positive connection between the plastic ring and the core can be provided via a tongue and groove connection. The plastic ring and the soul are particularly preferably connected to one another at the same time via a positive and a material connection. In general, it is particularly advantageous that when a seal comprising a plastic ring and core is provided, these two components (plastic ring and core) are connected to one another in such a way that when the connecting piece moves horizontally in the mounting arrangement relative to the drain pan core and plastic ring, there is always a common horizontal movement perform the nozzle. In one embodiment, the seal in the second contact section has a greater thickness along the vertical than in the first contact section, particularly preferably at least twice this thickness. A particularly reliable guidance of the seal in the receiving groove can thereby be ensured and at the same time a sealing contact of the seal on the connecting piece.

In one embodiment, the drainage channel is firmly connected to the connecting piece, the drainage channel and the connecting piece being particularly preferably each produced as separate components and then connected to one another. The gutter is particularly preferably made of a metal, whereas the nozzle is made of a plastic. The drainage channel is particularly preferably produced using a deep-drawing process.

In one embodiment, the nozzle has at least one horizontally extending web, which divides the nozzle into at least two partial nozzles, each of which extends vertically. Seals in the assembly arrangement the gasket closes all of the connecting pieces against the drain pot. For example, the at least two partial connectors can be spaced apart horizontally. For example, the at least two partial connectors can have a common boundary wall, so that they are connected to one another. In the assembly arrangement, the seal provides a circumferential seal of all the partial connections with respect to the drain pan. The odor trap particularly preferably comprises a plurality of partial odor traps, which can each be inserted into one of the partial connections. The partial odor traps are particularly preferably identical. The provision of several partial nozzles can have the particular advantage that, on the one hand, a sufficient drainage capacity of water is guaranteed by the drainage system located in the mounting arrangement and, on the other hand, the seal can be designed in such a way that it takes up little space and material horizontal load due to a horizontal displacement of the nozzle relative to the drain pot has such stability that it always ensures a reliable seal of the drain pot relative to the nozzle.

The connecting piece particularly preferably has a receiving section for receiving the odor trap, the odor trap being designed to be insertable into and removable from the receiving section. This makes it particularly easy to keep the drain system clean. The odor trap particularly preferably has a cup in which an immersion tube is removably arranged, the odor trap having a circumferential sealing seal on its top, via which it is connected in a sealing manner in the assembly arrangement to the connection piece. The blocking seal can prevent unpleasant smells from escaping from the pipe system between the nozzle and the odor trap into the room in which a drain system according to the invention is installed can be effectively prevented. In one embodiment, the connecting piece has a plurality of partial connecting pieces, each of which has a receiving section into which a partial odor trap can be inserted. The dip tube of the odor trap particularly preferably has the barrier seal.

In one embodiment, the cup of the odor trap has a horizontal cross section that extends in a first horizontal direction over a first extension length and in a second horizontal direction over a second extension length. The first extension length is at least 1.5 times, in particular at least twice as long as the second extension length. The dip tube has a pipe section with a clear cross section for the passage of water, which is arranged horizontally within the cup in the mounting arrangement and extends in the first horizontal direction over at least 70% of the first extension length and in the second horizontal direction over at most 70% of the extends second extension length, wherein in particular the cup extends in the second horizontal direction over at most 90%, in particular at most 80% of the extension length of the clear cross section of the nozzle in the second horizontal direction. The corresponding geometrical coordination between the cup and the immersion tube ensures in a particularly effective manner that on the one hand the immersion tube provides a sufficiently large clear cross section for wastewater and on the other hand wastewater that has flowed through the immersion tube through a sufficiently large clear cross section between the cup or The nozzle and immersion pipe can flow into the drain pot and from there into the end pipe connected to the drain pot. This is particularly due to the fact that the extension of the dip tube in the The first horizontal direction is relatively large and in the second horizontal direction is relatively small, based in each case on the dimensions of the cup or the nozzle. Particularly preferably, at least one flange extending in the second horizontal direction is provided on an outer side of the tube section of the dip tube for supporting the dip tube to the cup. This embodiment brings with it the particular advantage that the clear cross section through which the water which has flowed through the immersion tube for leaving the cup is always kept sufficiently large, since the flange causes the cup to collapse to the immersion tube is effectively counteracted. It is generally pointed out at this point that the first and second horizontal directions are particularly preferably perpendicular to one another.

In one embodiment, the cup is bounded in the second horizontal direction by two opposing walls, of which a first wall has at most 80% of a vertical extension length of the second wall over at least 50% of its horizontal extension length, the dip tube being at least one from the first wall is twice the horizontal distance from the second wall. This ensures a particularly good flow of waste water through the odor trap. This can be particularly advantageous for the drainage performance of a drainage system installed in a mounting arrangement in a room floor.

Each partial connector particularly preferably has a receiving section assigned to it, in which an odor trap assigned to it is arranged. In the assembly arrangement, two adjacent odor traps are particularly preferably arranged with respect to one another in such a way that their dip tubes are arranged offset to one another in the second horizontal direction. The dip tubes overlap in the second horizontal direction only partially at most. This can ensure that wastewater flowing out of one of the adjacent odor traps can flow past the adjacent odor trap through the largest possible clear cross section.

In one embodiment, the sealing sleeve is designed as a flat membrane, on which a mounting frame is provided which encloses, in particular, encloses, an opening provided in the sealing sleeve. The drain pot has on its upper side a circumferential groove corresponding to the mounting frame, which surrounds the inlet opening of the drain pot in a closed manner. In the mounting arrangement, the mounting frame is inserted in the groove in a circumferential manner, in particular in a closed circumferential manner, in a sealing manner to the drain pan. The provision of a corresponding sealing sleeve with a mounting frame makes the installation of the drain system according to the invention on site, in particular the sealing of the drain pan after laying a screed around the drain pan, particularly easy. Because the processing tradesman can seal the sealing sleeve by hand without tools on the drain pan by pressing the mounting frame into the groove, after which he can then glue the sealing sleeve to the screed. The mounting frame is particularly preferably injection-molded onto the flat membrane using an injection molding process and made of plastic. In one embodiment, a circumferential sealing element, preferably made of PPE, is provided in the groove or on the mounting frame. In one embodiment, the mounting frame is made of PP. In one embodiment, the flat membrane is designed as a waterproof fleece. In one embodiment, the flat membrane is designed as a three-layer "tri-laminate" that comprises two PP spunbonded fabrics, between which a layer of thermoplastic elastomer (TPE), in particular comprising EPDM components, is arranged. As a result, it is particularly preferred to provide a sealing sleeve, the flat membrane of which can be stretched in one direction of its flat extent, as a result of which the flat membrane can be geometrically adapted particularly well to the floor environment or room environment with which it is to be adhesively bonded.

In one embodiment, the mounting system comprises a building protection system, which is designed as a protective cover that can be mounted on the top of the drain pan for closing the drain pan. In an installation arrangement of the drain system, the building protection is mounted on the top of the drain pot and forms a peripheral upper edge of the drain system. The installation arrangement designates such an arrangement of the elements of the drain system according to the invention, in which these elements are arranged at least temporarily, while the drain system is installed in the floor of a room. For example, the mounting system according to the invention can be arranged in the installation arrangement while the drain pan is connected to a drain pipe and while the screed is laid on the floor of a room around the drain pan. The building protection can ensure that no coarse contaminants get into the drain pot and in particular no coarse contaminants get into a groove provided on the top of the drain pot for receiving the mounting frame of a sealing sleeve. The top edge of the building protection, which also forms the circumferential top edge of the drain system in the installation arrangement, can act as a peel edge for the screed installer. In particular, in the installation arrangement, the top of the building protection forms the top of the drain system, via which a screed installer can pull off.

The building protection particularly preferably comprises a one-piece component, in particular a plastic component produced by injection molding or otherwise, which has a fastening frame and a center piece which is horizontally surrounded by the fastening frame. In the installation arrangement, the building protection with the component comprising the fastening frame and the center piece is mounted on the top of the drain pan. The building protection component has a predetermined breaking seam between the fastening frame and the center piece for breaking out the center piece. The center piece is designed so that it can be placed on the inlet opening of the drain pan and thereby covers the inlet opening of the drain pan. The particularly advantageous design of the building protection therefore makes it possible, on the one hand, to provide a top edge of the drain system, possibly functioning as a peeling edge for a screed layer, via the building protection in the installation arrangement of the drainage system, whereas after laying the screed and during the further installation steps of the building protection in one Space the center piece can continue to act as protection against coarse contamination of the drain pan. For example, the center piece can cover the inlet opening of the drain pan after the sealing sleeve has been glued to the screed and before the drain gutter with the nozzle is inserted into the drain pan. Correspondingly, the building protection is particularly advantageously designed such that it covers the groove for receiving the mounting frame in the installation arrangement in order to protect the groove against contamination.

In one embodiment, the center piece has a passage opening. This passage opening enables leak tests to be carried out in the drain pipe system with the drain pot connected to them, since the Passage opening allows water to be poured into the drain pan. By providing the passage opening, it is thus possible for the building protection to remain mounted on the drain pot to ensure protection of the drain pot, while tests are carried out on the drain pipe system before the room floor is finally completed (including the completion of the floor covering and the installation of the drainage channel) can. The building protection particularly preferably has a film which is designed as a covering over the component and comprises a fastening frame and a central piece and forms the top of the building protection. This film can be designed, at least in sections, as an adhesive film that can be detached from the component. Such a coating can ensure reliable closure of a passage opening provided in the center piece. The passage opening in the center piece is particularly preferably covered by a removable adhesive film section of the covering, so that the passage opening is accessible if necessary by removing this adhesive film section and can then be closed again by placing this adhesive film section on. The provision of such a covering can also have the advantage that the surface of the component comprising the fastening frame and center piece is not contaminated when the screed is being laid, since it is protected by the covering. This can be advantageous, for example, if the fastening frame is fastened to the drain pot by means of screws and contamination of the screws with screed is undesirable, since this makes it more difficult to loosen the screws for dismantling the fastening frame. The covering particularly preferably extends horizontally over at least 0.5 cm, in particular over at least 1 cm beyond the horizontal extent of the center piece. This can have the particular advantage that when the center piece breaks out of the named component, the center piece can rest on the inlet opening and the sections of the coating projecting horizontally beyond the center piece additionally ensure a sealing of the inlet opening. Particularly preferably, the installation of the drain system in a room comprises a work step in which the drain system is processed in the installation arrangement in such a way that a pressure is generated on the center piece towards the drain pot, while the building protection is mounted on the drain pot, with the pressure being applied the center piece towards the drain pan is broken out of the mounting frame and, together with the cover, comes to rest on the inlet opening of the drain pan.

In the Figures 1 to 3 An embodiment of an execution system according to the invention is shown in different views. While in Figure 1 a cross section along the vertical Z and along the horizontal X of the drain system is shown, which is located in the mounting arrangement and is integrated in a room floor of a room is in Figure 2 an exploded view this execution system according to the invention shown and in Figure 3 a partial exploded view, in which various in Figure 2 visible individual parts are assembled into elements of the drain system. In the following, the Figures 1 to 3 illustrated embodiment of a drain system according to the invention in more detail with reference to all three figures.

The drain system according to the invention comprises a drain pot 1 which has a connection piece 150 for connection to a drain pipe. The base body 15 of the drain pot 1 with the connector 150 are integrally produced in one piece as a plastic component by means of an injection molding process. The drain pan 1 further comprises a lid 14, which is also integrally produced as a plastic component by means of an injection molding process. The lid 14 of the drain pot 1 forms a receiving groove in which, in particular, from Figure 1 can be seen, a seal 4 is arranged in the assembly arrangement of the drain system. This receiving groove of the drain pot 1 is formed from an upper web 11 and a lower web 13, which in the present case is designed as a press ring 13. The cover 14 of the drain pot 1 has a wall in which locking projections 12 are provided, with which the press ring 13 is locked for producing the assembly arrangement of the drain system. In the manufacture of the drain pan 1, the seal 4 comprising a closed circumferential plastic ring 41 and a closed circumferential core 42 is first placed on the upper web 11 and then the press ring 13 is pushed over the locking projections 12 until it snaps behind the locking projections and thereby the Press seal 4 vertically against the upper web 11. The upper web 11, like the press ring 13, has a closed circumferential design, in the assembly arrangement as well Figure 1 visible, closed around the nozzle 3.

After the cover 14 with the press ring 13 has been joined together with the seal 4 comprising the plastic ring 41 and the core 42, the upper side of the base body 15 is then welded to the underside of the cover 14, so that the cover 14 and the base body 15 together form an integral housing wall of the drain pan 1 form.

The seal 4 is realized in the present case by a one-piece plastic ring 41 and a core 42, the plastic ring 41 having a first contact section 402 with which it presses horizontally against the connector 3 in the assembly arrangement of the drain system, and a second contact section 401 with which it is arranged in the mounting arrangement of the drain system within the receiving groove of the drain pot 1 and presses vertically against the drain pot 1, in the present case against the upper web 11 of the drain pot 1. By this pressing, the plastic ring 41 creates a sealing connection both to the drain pan 1 and to the nozzle 3. In the present case, the core 41 is designed as a circumferentially closed metal ring which has circular cutouts. The plastic ring 41 has projections corresponding to the cutouts, which are provided on the underside of the plastic ring 41. In Figure 1 it can be seen that the plastic ring 41 with its projections is snapped into the recesses of the core 42 designed as a metal ring. As a result of this latching, a positive connection is provided horizontally circumferentially around the connector 3 between the core 41 and the plastic ring 41 of the seal 4, so that the seal 4 has sufficient stability for the seal 4 to move relative to the drain pan 1 when the connector 3 is moved horizontally completely performs a common movement with the nozzle 3 relative to the drain pot 1 and continuously rests sealingly against both the nozzle 3 and the drain pot 1.

That in the Figures 1 to 3 The drain system according to the invention furthermore has a building protection which comprises a component 100 which is produced in one piece by injection molding and a coating 101. The component 100 has a center piece and a fastening frame. In the installation arrangement of the drain system according to the invention described, the coating 101 is arranged on the top of the component and glued to this component. The coating 101 is designed as a transparent adhesive film. In general, the building protection is designed to be transparent at least across horizontal sections, so that a craftsman can look into the drain pot from above when installing the drain system in the installation arrangement and thus detach the building protection from the drain pot while the drain pot is connected to a drain pipe or during installation of screed around the drain pan is usually necessary. In the drain system according to the invention described, the center piece has a passage opening 112, which is reversibly closed by a detachable adhesive film section 1121 of the cover 101. The center piece is furthermore only connected to the fastening frame of the building protection 100 via 8 narrow webs 111, a predetermined breaking seam 110 being provided between the webs by material cut-out, so that the center piece can be broken out of the fastening frame very easily. For this purpose, press depressions 113 are specifically provided for displaying the positions at which a press force is to be applied to break out the center piece. In the installation arrangement of the mounting system, which in Figure 3 is shown, the building protection is screwed to the drain pot 1 and covers the inlet opening of the building protection 1. In addition, the building protection in the installation arrangement protects a groove provided on the top of the drain pot 1, which is particularly in Figure 1 and Figure 2 can be seen. In this groove is in the Assembly arrangement of the drain system, which in Figure 1 is shown, a mounting frame 61 of the sealing sleeve 6 of the drain system is arranged. This mounting frame 61 is closed all around an opening of the sealing sleeve 6. The mounting frame 61 is injection molded onto the otherwise flat membrane of the sealing sleeve 6 and ensures a sealing connection in the mounting arrangement between the sealing sleeve 6 and the drain pot 1, a closed peripheral sealing element 610 being provided in the receiving groove for this purpose. The sealing sleeve 6 is, as in Figure 1 can be seen in the assembly arrangement with a floor 9 and a wall 90 sealingly connected.

In the assembly arrangement of the drainage system, the building protection is removed from the drain pot 1 and the sealing sleeve 6 is sealingly connected to the drain pot 1 via its mounting frame 61, the connector 3 being inserted into the drain pot 1 through the opening of the sealing sleeve 6 and through the inlet opening 1000 . The connector 3 has two partial connectors, which are separated from one another by a horizontally extending web 17. On the outside of the connection piece 3, the seal 4 with its first contact section 402 lies sealingly within the drain pot 1, the connector 3 being vertically displaceable relative to the seal 4 and also relative to the drain cup 1 while maintaining the seals mentioned. In the assembly arrangement, a partial odor trap 5 is arranged in each partial connector of the connector 3. Each partial odor trap 5 is of identical design, and the partial odor traps 5 together form the odor trap of the drain system. Each partial odor trap 5 has a cup 51 and an immersion tube 52 that is arranged in the mounting arrangement inside the cup 51. The dip tube 52 has on his a sealing seal 520, with which it rests sealingly on the receiving section of the partial connector, in which the respective partial odor trap 5 is received. Each dip tube has a tube section with a clear cross section for the passage of water, which is arranged horizontally in the mounting arrangement inside the cup. The clear cross section of the dip tube extends horizontally over a first extension length in a first horizontal direction, which is at least 70% of a first extension length of the cup in the first horizontal direction. In addition, each dip tube 52 extends in a second horizontal direction that is perpendicular to the first horizontal direction over a second extension length that is at most 70% of the second extension length of the cup in the second horizontal direction. The first extension length of the cup is more than twice the second extension length of the cup. Cup 51 and dip tube 52 are thus each elongated. Because of the relative dimensions of the cup 51 to the dip tube 52, the dip tube 52 extends almost over the entire width of the interior of the cup 51, which is defined by the first extension length, whereas it is only slightly more than half the second extension length of the cup extends. The dip tube 52 has on the outside of its tube section a flange 521 which extends in the second horizontal direction and supports the cup 51 and the dip tube 52 against one another. This provides a sufficiently large clear cross-section for waste water passing through the drain system and flowing vertically through the dip tube 52, through which this waste water can run out of the cup 51 from the lower end of the dip tube 52. In the described embodiment, the cup is bounded in the second horizontal direction by two opposite walls, the pipe section of the dip tube lies very closely on a first of the two walls and is spaced considerably further apart from the opposite wall, this distance being ensured by the flange 521. This wall of the cup 51, which is spaced apart from the pipe section of the immersion pipe 52, has a significantly smaller vertical extent than the opposite wall, which further improves the escape of waste water from the partial odor trap 5. Each partial odor trap 5 also has a removal bracket 53. This removal bracket is attached at an angle to the immersion tube 52, so that it has a substantially smaller vertical extension length in a first position than in a second position angled to the first. In the second position, the removal bracket 53 projects vertically from the partial odor trap 5, as a result of which the partial odor trap can be removed very easily. In the assembly arrangement, which in Figure 1 is shown, the removal bracket 53 is in its first position. In this position, it is arranged at a distance from the top of the drainage channel 2 in the assembly arrangement. The provision of a corresponding removal bracket is generally advantageous for a large number of embodiments according to the invention.

The gutter 2 is glued to the top of the nozzle 3. The gutter 2 is made in the present case from a deep-drawn stainless steel. The drainage channel 2 has an opening which is covered by a grate 20 which can be removed from the drainage channel 2, as a result of which the partial odor traps 5 and the nozzle 3 are accessible from above. The grate 20 has a slot 21 for discharging the waste water. The gutter 2 also has support elements 200, by means of which it can be supported on a screed placed on a floor.

From the figures and the above explanation it follows that in the assembly arrangement, the drain system is installed in a room floor in such a way that the drain pot 1 is set up on a floor via height-adjustable feet 16 and is connected to a drain pipe, the drain pot 1 being cast in a screed. In the assembly arrangement, the seal 4 is arranged in the drain pan 1, which runs closed all the way around a nozzle 3 to which the drainage channel 2 is attached. This drain connector 3 is movable together with the drainage channel 2 horizontally relative to the drain pot 1, while the seal 4 moves with the connector 3 and continuously ensures a sealing connection between the connector 3 and drain pot 1 during the horizontal movement. As a result, the drainage system according to the invention is designed such that when tiles 7 are installed on a screed 9 or on a wall 90, the drainage channel 2 can be aligned so that it is arranged as optimally as possible relative to the tiles and then with silicone joints 10 the tiles 7 can be sealingly connected.
