    Description: The invention relates to the field of toilets, in particular ceramic toilets, such as toilets.
    Typically toilet bowls are made of ceramic. The bowl itself, as well as the water inlet and rinse distributor for the rinse water are cast from ceramic. Ceramic is expensive and a casting process, depending on the design of the object to be cast, for example with various openings and passages, is very complex. Also, water inlet and rinse distribution areas are difficult or impossible to access for cleaning or descaling. In addition, a water pipe is connected by inserting the end of the pipe of the water pipe into the ceramic water inlet. Such a connection is highly susceptible to leakage, in particular due to the generous tolerances of the inner diameter of the ceramic water inlet.
    It is therefore a need to create toilets with a flushing water inlet that are less prone to leakage. Furthermore, there is a need to create toilets with a flushing water inlet and distribution system that simplifies the manufacture of conventional toilets.
    The invention relates to a toilet, preferably mainly made of ceramic, comprising a bowl with a wall passage located in an upper region of a rear bowl wall section and having a wall opening. The toilet also has a water inlet that connects to the wall passage and can be connected to a rinsing water pipe of a water pipe, the water inlet being formed by a plastic water inlet pipe.
    The water supply line can be designed to be removable. The water supply line can be connected to the wall passage, for example clamped therein. The water supply line can also be connected to a flushing distributor fitted in the wall opening of the wall passage. This can be a direct connection between the two elements. The rinse distributor, and preferably also the water supply line, preferably extend into the wall passage where the two elements are connected to one another.
    A connection of the rinsing distributor and water supply line can also be realized via intermediate elements, for example a fastening line. The fastening line is installed in the wall passage. A flushing distributor is provided at one end of the fastening line and the water supply line at the end of the fastening line opposite the flushing distributor.
    The water supply line is connected directly to the rinse distributor or via an intermediate piece, preferably a fastening line. Direct or indirect connections are preferably realized by screwing.
    Typically, a toilet has a bowl and at least in the region of the wall opening has an edge which projects into the interior of the bowl towards the bowl bottom and is spaced from the rear bowl wall section. This edge optically covers the flushing distributor area.
    In embodiments of the invention, the toilet has a ceramic flushing distributor, which is connected to the edge and the wall passage. In such embodiments, the plastic water supply line is preferably connected directly to the wall passage, for example to the end of the wall passage opposite the flushing distributor.
    Alternatively, a plastic flushing distributor can be introduced into the wall opening and connected, for example, to the water supply line.
    In a system in which a water supply line made of plastic is provided, the manufacture of a toilet is simplified. It enables the replacement of ceramic parts. A ceramic water inlet can be completely replaced by the water inlet pipe. A mold for a toilet can be greatly simplified and ceramic and weight can be saved.
    In particular, a connection to a water pipe, which is usually a tube made of plastic, but can also be made of metal, is improved. Usually the end of the pipe of the water pipe is inserted sealingly into the ceramic inlet. Such a connection is highly susceptible to leaks, in particular due to the generous tolerances of the inner diameter of the ceramic water inlet.
    In contrast, the connection of a pipe end on or in a plastic supply line can be realized very easily, for example with a union nut. Plastic connections can be assembled very tightly and are not very susceptible to leaks. In addition, plastic lines and metal pipes have lower tolerances, which simplifies the production of standardized connections.
    With the water supply line made of plastic, an element of the flushing water supply in a toilet can be produced with few deviations. This has a positive effect on a regular, constant washing result.
    A hollow volume formed by the edge, a bowl top and the rear bowl wall section of the toilet bowl is preferably completely open towards the bowl bottom.
    CH 714 828 A2 The edge which is open at the bottom allows simple and direct access to the wall opening. Installation of a flushing distributor is not only simplified by the open area between the edge and the rear bowl wall section, but is even made possible in the first place.
    If not only a water inlet, but also a flushing distributor made of plastic, this allows an additionally simplified manufacture of a toilet. In particular, it enables the replacement of other ceramic parts. For example, a mold can be further simplified and ceramic can be saved. This means that an otherwise identical toilet can be manufactured more easily and with less weight. Compliance with tolerances in the manufacture of plastic elements is also comparatively simple, so that a regular, constant rinsing result can be achieved. Tolerances in the production of a ceramic sanitary article can also be compensated for with the water inlet and rinsing distributor made of plastic.
    The water supply line preferably has an internal thread which corresponds to an external thread of another element.
    Other types of connection are also possible, for example, a water supply line can also be connected by means of a bayonet lock, by means of a snap lock or simply by means of clamps to the flushing distributor or a fastening line.
    A water supply line is preferably tubular, wherein different diameters can be provided. In particular, the diameter of the water supply line can be adapted to national or international standards. An end of the water supply line to be connected to a water pipeline preferably has a standardized diameter, for example EN80.
    [0021] In preferred embodiments, the water supply line has two line sections. A first line section has a first inner diameter and a second line section has a second inner diameter. The first inside diameter is smaller than the second inside diameter. The water supply line preferably consists of two line sections with different diameters.
    The two line sections of the water supply line are preferably arranged coaxially.
    Preferably, a fastening line made of plastic is provided for fastening the flushing distributor to the toilet. The flushing distributor has an inlet opening, at least one outlet opening arranged at an angle to the inlet opening, and fastening means. The fastening means of the flushing distributor are preferably arranged in the outer region of the inlet opening. The inlet opening is preferably completely accessible.
    The at least one outlet opening of the flushing distributor attached to the fastening line preferably points towards the bottom of the bowl. The fastening line has fastening means, which fastening means of the fastening line correspond to the fastening means of the flushing distributor, for the preferably detachable attachment of the flushing distributor to the fastening line.
    The fasteners of the flushing manifold and mounting line are preferably arranged and designed so that they allow removal and attachment of the flushing manifold from and to the mounting line in a direction perpendicular to a central axis of the mounting line. The central axis of the fastening line preferably corresponds to a longitudinal axis of the water supply line.
    Detachable rinsing distributor and fastening line allow easy cleaning and replacement of the rinsing distributor. The fastening line can be fastened in a toilet and preferably connected to a water supply line. If necessary, the flushing distributor can be attached to and removed from the fastening line. After removing the rinsing distributor, cleaning in the area of the fastening line is also possible.
    The attachment and detachment of the flushing distributor in a direction perpendicular to a central axis of the fastening part also enables the detachable attachment of a flushing distributor to a toilet, where a ceramic edge makes direct access to a flushing water inlet impossible. The direction perpendicular to the central axis preferably corresponds to a direction downwards or from below in relation to the toilet, for example the edge of a toilet bowl.
    The flushing distributor system is introduced and aligned in the wall opening and in the wall passage in such a way that flushing water guided through the flushing distributor is directed at least in the direction of the bowl bottom along the inside of the rear bowl wall section. Lateral areas of the inner wall are preferably also wetted.
    [0029] “perpendicular to the central axis” of the fastening line means a direction of 90 degrees to the central axis. However, “perpendicular to the central axis” includes exactly 90 degrees in relation to the removal and attachment direction of the flushing distributor, as well as a few degrees deviation of exactly 90 degrees. For example, depending on the design of the fastening means, these can be tilted or slightly angled with respect to the central axis of the fastening line. “Vertical to the central axis” thus also includes directions that deviate by up to 20 degrees from the vertical of the central axis of the fastening line.
    Fastening means of flushing distributor and fastening line are preferably designed such that the flushing distributor can be removed from or attached to the fastening line by movement in one direction exactly 90 degrees perpendicular to the central axis of the fastening line.
    CH 714 828 A2 The fastening means of the flushing distributor and fastening line, as well as the at least one outlet opening of the flushing distributor, are preferably designed and arranged such that they remove and attach the flushing distributor from and to the fastening line essentially in a direction of the at least one outlet opening allow the flushing distributor. An outlet opening is arranged in the flushing distributor system in such a way that, when the flushing distributor system is installed, it points in a toilet in the direction of the toilet outlet or in the direction of a bowl bottom. However, this direction typically does not point exactly vertically downwards, nor exactly perpendicular to the central axis of the fastening system, but rather deviates from the vertical. This allows flushing water to be directed through the outlet opening of the flushing distributor not vertically downwards, but parallel to a bowl's inner wall or towards the toilet outlet. “Essentially” in the direction of the outlet opening thus includes a deviation of, for example, up to 45 degrees to the vertical.
    The attachment means are connected to one another for attaching the flushing distributor to the attachment line. The fastening means are detached from one another in order to remove the flushing distributor from the fastening line.
    The fastening means of the flushing distributor and the fastening line are preferably designed in such a way that the fastening means can be connected and detached by a relative movement of the flushing distributor and fastening line. Preferably no tools are required to connect and detach the fasteners.
    The fastening means can be connected and released by a linear movement or by a rotational movement or by a combination of a linear and rotational movement. Linear and rotational movements can also be combined. For example, the fastening means can be loosened initially by a rotational movement, the flushing distributor then being removed by a linear movement perpendicular to the central axis of the fastening line.
    Preferably, the fastening means of the flushing distributor and the fastening line enable the fastening means to be loosened and connected, and a removal and attachment of the flushing distributor by means of a linear relative movement, for example an exclusively linear relative movement of the flushing distributor and fastening line.
    Preferably, the fastening means of the flushing distributor and the fastening line are arranged and designed in such a way that they enable removal and attachment of the flushing distributor from and to the fastening line by means of an exclusively linear movement in the direction perpendicular to the central axis of the fastening line.
    The fastening means of the flushing distributor and the fastening line are preferably designed as mutually corresponding interlocking grooves and ridges. The fastening means of the fastening line can be designed as a rail and the fastening means of the flushing distributor as a comb or longitudinal projection which is guided in the rail of the fastening line. Comb and rail can also be attached to the other element of the flushing distribution system. A comb of the fastening line is then guided in a groove or rail of the flushing distributor and the two elements are thus attached to one another.
    Alignment and insertion aids can be provided on the rinsing distributor and fastening line. These make it easier to position the fastening means against one another and preferably simplify the fastening process, for example mutually guiding, such as inserting a comb in a groove.
    The fastening means of the flushing distributor and fastening line can additionally form a snap lock. For example, the flushing manifold and fastening line can be provided with projections which are slightly offset from one another and which are snapped in when the flushing distributor and fastening line are completely connected to one another. A snap lock can also be designed differently, for example as an interlocking projection and notch.
    [0040] A snap lock can preferably be released with slightly increased effort. A snap lock preferably prevents the fastening means from unintentionally loosening, for example due to flushing water pressure or vibrations.
    [0041] The fastening line preferably has a tubular part. The fastening line is preferably a tubular part provided with fastening means. The fastening means of the fastening line corresponding to the fastening means of the flushing distributor are preferably attached to one end of the pipe part.
    [0042] The fastening line preferably has a stop projecting radially outwards at this one end. In the assembled state, the stop can restrict movement of the fastening line or the flushing distribution system in a wall opening in a wall of a toilet at least in one direction.
    The stop can be formed by the fastening means or as a separate stop, for example a projection projecting radially outwards.
    Preferably, the stop is formed by the fastening means. For example, a rear side of a fastening means forms a stop, while a front side of the fastening means corresponds to the fastening means of the flushing distributor.
    [0045] The rinsing distributor has at least one outlet opening. If only a single outlet opening is provided, it preferably does not point in only one direction, but rather allows rinsing water to be distributed in several
    CH 714 828 A2
    Directions. The outlet opening can be designed, for example, as an elongated outlet opening, for example as a curved slot. Preferably, a single outlet opening enables flushing water to be distributed in a fan shape. In this way, rinsing water is not only directed in the direction, for example downward, towards the outlet of a toilet, but also allows a wide side wetting and washing off of an inner wall of the toilet.
    Preferably, multiple outlet openings are provided in the purge manifold. If there are several outlet openings, these are arranged at different areas of the flushing distributor and preferably point in different directions. This allows flushing water to be directed through the several outlet openings into different areas of an inner wall of the toilet.
    [0047] In preferred embodiments of the rinsing distributor, the rinsing distributor has three outlet openings. A first of the three outlet openings is preferably arranged perpendicular to a second and third outlet opening of the three outlet openings. The second and third outlet openings preferably lie on a line and allow a flushing water distribution essentially in opposite directions. A flushing distributor with three outlet openings is preferably designed as a T-piece, one side of the T-piece having the inlet opening. This is preferably arranged perpendicular to all outlet openings so that a flushing water jet enters the flushing distributor through the inlet opening and is then prevented from continuing to flow in a straight line by a wall of the T-piece. The flushing water is distributed through the angled outlet openings, for example perpendicular to a central axis of the inlet opening.
    A central axis of the inlet opening of the flushing distributor preferably corresponds to the central axis of a fastening line or the longitudinal axis of the water supply line or the central axis of a fastening line and the longitudinal axis of the water supply line.
    Flush distributor and fastening line, as well as fastening line and water supply line can be connected to one another in a fixed or removable manner. They can also be made as common parts. The fastening line and water supply line are preferably separate elements which are connected to one another, preferably screwed together.
    Threaded plastic articles are simple and inexpensive to manufacture and also form a secure and tight connection.
    A fastening line preferably has an external thread and the water supply line has an internal thread corresponding to the external thread of the fastening line. Reverse threads or other types of mounting are also possible, as described above.
    [0052] The elements of the flushing distribution system can be in several pieces or in one piece. The rinsing distributor, fastening line or water supply line are preferably in one piece. The rinsing distributor, fastening line and water supply line are preferably in one piece. Flushing distributor and fastening line, as well as fastening line and water supply line can also be in one piece.
    The components of the rinse distribution system including water supply line are made of plastic, for example from a plastic by injection molding. The plastic used should be chemically stable and mechanically strong enough for assembly and, if necessary, a multiple connection and disconnection of the individual elements of the flushing distribution system. Polypropylene (PP) is preferably used for the production.
    Unless explicitly stated otherwise, all of the openings in the rinsing distributor system preferably have a round inner diameter. Other diameter shapes, for example elliptical, are also advantageous in terms of uniform water distribution or optimized cleaning. However, diameters other than round are also possible, for example square or polygonal diameters.
    [0055] The purge manifold system may further include a flow restrictor. This can be installed in any element of the flushing distribution system. A flow limiter is preferably arranged upstream of the inlet opening of the flushing distributor. A flow limiter is preferably introduced into a plastic element, such as a fastening line or a water supply line.
    If the flushing distributor and a water supply line and possibly also intermediate elements such as fastening lines are made of plastic, a toilet in the area of the flushing distributor and the water inlet can be made very simple. A toilet bowl can have a much simpler shape than with a flushing distributor integrated in the ceramic bowl.
    Preferably, a toilet in the area of the flushing distributor is essentially limited to a wall opening in a bowl wall. A mold can be greatly simplified and additional ceramic and weight can be saved. A bowl wall then essentially has only one wall opening for attaching the flushing distribution system. For example, a fastening line of the flushing distribution system is positioned in the wall opening of the bowl wall. Depending on the design of the flushing distributor system, the water supply line is mounted on the rear of the wall at one end of the fastening line. The flushing distributor is attached to the inside of the bowl at the opposite end of the fastening line and attached to the loading device via corresponding fastening means
    CH 714 828 A2 fastening line removable or fixed. If necessary, the water supply line is already connected to the fastening line or is manufactured as a common element.
    The water supply line or the entire rinsing distributor system is preferably held and preferably sealed by stops in the wall opening and on the wall. Seals, such as sealing rings, for example O-rings, V-rings or flat seals, can also be provided for sealing.
    A rear bowl wall section in the region of the wall opening thus has no additional ceramic projections or tubular inflow parts.
    Accordingly, a bowl wall around the wall opening can have a thickness that is as uniform as possible.
    A wall passage preferably determines a thickness of the rear bowl wall portion adjacent the wall opening. This thickness is preferably equal to or less than 70 millimeters. In particularly preferred embodiments of the toilet, this thickness is equal to or less than 40 millimeters, preferably equal to or less than 20 millimeters, for example between 10 millimeters and 20 millimeters or between 12 millimeters and 18 millimeters, such as, for example, 5 millimeters.
    A rear bowl wall section adjoining the wall opening preferably has a thickness of equal to or less than 25 millimeters.
    Depending on the position of the wall opening in the bowl wall or a wall passage, a thickness of the bowl wall that is as uniform as possible extends around the wall opening over an extended or less extended area. A wall opening in the bowl wall or a wall passage is preferably arranged as close as possible to the top of a bowl.
    The thickness of the bowl wall around the wall opening that is as uniform as possible extends over at least 3 millimeters, preferably over at least 5 millimeters, around the wall opening. In certain embodiments of a toilet bowl, the thickness, which is as uniform as possible, extends over approximately 25 millimeters around the wall opening.
    The extent of the thickness of the wall opening, which is as uniform as possible, is limited in the upward direction by the top of the bowl. Downward, towards the bowl bottom, the rear bowl wall section adjoining the wall opening has a length of preferably at least 10 millimeters, particularly preferably over a length of at least 25 millimeters in the direction of the bowl bottom, a thickness of 70 mm or less, particularly preferably equal or less 40 millimeters, for example a thickness between 10 millimeters and 20 millimeters or between 12 millimeters and 18 millimeters.
    The invention is explained in more detail below with reference to figures. It shows:

    FIG. 5 shows a side view of the flushing distribution system according to FIG. 4 without water supply line;
    6 shows a front view of a fastening line, for example according to FIGS. 4 and 5;
    7 shows a horizontal cross section through the flushing distributor area according to FIG. 3.
    In the figures, the same reference symbols are used for the same or similar elements.
    Fig. 1 shows a conventional toilet 6, in which a flushing manifold integrally formed with the edge 731 and a wall passage 610 has been replaced by a plastic flushing distributor 70.
    The toilet 6 comprises a bowl 60 with a bowl bottom 61, a substantially circumferential bowl wall 62 and a bowl top 63. The bowl top 63 is formed by a flat surface, the bowl except for a rear bowl area, the area for the rinse water supply, has a thickened edge 630.
    In a rear area of the bowl 60, the area of the rinse water supply, the bowl 60 has an edge 731 projecting downwards into the bowl in the direction of the bowl bottom 61. This edge covers the rinse distributor 70.
    [0070] The rear bowl wall area 600 has a wall passage 610 having a wall opening 521, into which the flushing distributor 70 is introduced. Adjoining the wall passage 610 is a water inlet 620. This is integrally formed with the wall passage 610 and the bowl 60 made of ceramic. A water line (not shown) is sealed from the rear through the upstream end 75 of the water inlet to the water inlet 620.
    CH 714 828 A2 The rinsing distributor 70 is fastened with the aid of a securing part 71 in the wall passage 610 in the toilet bowl 60. The securing part 71 is essentially a plastic tube, which has an internal thread 710 at one end. The internal thread 170 corresponds to the external thread 700 of the flushing distributor.
    The rinsing distributor has a beak-like projection 72, which is open at the bottom, for introducing rinsing water towards the bowl bottom 61.
    The rinse manifold 70 is substantially horizontal, i.e. a central or longitudinal axis of the securing part 71 is introduced essentially horizontally in the toilet 6. Once installed, the flushing distributor is firmly installed in the toilet and cannot be replaced without dismantling the toilet.
    2 shows a cross section through the flushing water inlet and distributor area of a toilet according to the invention.
    The toilet in turn comprises a bowl with a substantially circumferential bowl wall and a bowl top 63. The bowl top 63 is in turn formed by a flat surface. In a rear area of the bowl, the area of the rinse water supply, the bowl has an edge 731 projecting downwards into the bowl in the direction of the bowl bottom. This edge essentially covers the flushing distributor 70.
    The toilet bowl is changed in a rear area, in the area of the water supply compared to FIG. 1. The water supply is made of plastic.
    The water inlet 620 according to FIG. 1 is essentially replaced by a water supply line 30 made of plastic. The water inlet line 30 essentially consists of an inlet pipe 32 and a connecting pipe 31 adjoining it coaxially. The connecting pipe 31 has an internal thread 710 along its entire length. The internal thread 710 and the internal diameter of the connecting pipe 31 correspond to the external thread 700 and the external diameter of the fastening thread of the flushing distributor 70.
    The threads 700, 710 connect the water supply line 30 and the rinsing distributor 70 directly to one another.
    The inlet pipe 32 of the water inlet line 30 has a larger inner diameter than the connecting pipe 31 and also as a through opening 34 at the downstream end of the inlet pipe 32. The through opening 34 has the same diameter as the inner diameter of the fastening thread of the flushing distributor 70.
    The different pipe diameters of the water supply line 30 form a shoulder 35 which, together with the flushing distributor 70, enables the entire flushing water inlet and distribution system to be fixedly mounted.
    The rear bowl wall area 600 has a wall passage 610 having a wall opening 521, into which the flushing distributor 70 is introduced and fastened therein together with the water supply line 30. Following the wall passage 610, there is no longer any ceramic water inlet. A water pipe (not shown) is sealed from the rear to the upstream end 33 of the water supply pipe 30.
    The water supply line 30 is oriented essentially horizontally, i.e. a central or longitudinal axis of the water supply line is introduced essentially horizontally in the toilet.
    The entire area of the flushing water supply and inlet into the toilet bowl is ceramic-free except for the wall passage 610. An edge 731 could also be dispensed with purely technically, since the flushing distributor 70 takes over the entire water distribution in the toilet bowl. For visual and design reasons, however, an edge is reluctant to do without.
    Around the wall opening 521 of the wall passage 610, the thickness of the wall is greater than in a lower region. In the example shown, the thickness of the wall around the wall opening 531 is approximately 65 mm. This range of thickness can extend over several centimeters. However, the wall passage 610 is located as high as possible in the toilet bowl and thus as close as possible to the top of the bowl 63 in order to allow water to flow in as far as possible from the top of the bowl. The same thickness range around the wall opening 610 thus only extends over approximately 25 mm. The same thickness range of approx. 65 mm also extends downwards towards the bottom of the bowl 61 about 25 mm.
    FIG. 3 shows a toilet 5 with a built-in separable flushing distributor system 1 including a water supply line 30. The flushing distributor system is shown in detail in FIG. 4 and with a V-seal 40. FIG. 4 shows a cross section and an exploded view of the flushing distribution system according to FIG. 3.
    The rinsing distributor system 1 consists of a rinsing distributor 10, a fastening line 20 which can be detachably connected to the rinsing distributor and a water supply line 30, all made of plastic, for example PR. The fastening line 20 is a tube 21 which has a radially projecting edge 220 at one end having. The edge 220 is designed, apart from a lower area, as a rail 22 accessible from below.
    The water inlet line 30 essentially consists of an inlet pipe 32 and a connecting pipe 31 adjoining it coaxially. The connecting pipe 31 has an internal thread 310 over its entire length. The internal thread 310 and the internal diameter of the connecting tube 31 correspond to the external thread 210 and
    CH 714 828 A2
    Outside diameter of the fastening line 20. The water supply line 30 and fastening line 20 are connected to one another by means of the threads 310, 210.
    The inlet pipe 32 of the water inlet line 30 has a larger inner diameter than the connecting pipe 31 and also as a through opening 34 at the downstream end of the inlet pipe 32. The through opening 34 has the same diameter as the inlet opening 23 and outlet opening 24 of the fastening line 20 and the inlet opening 15 of the flushing distributor 10. Preferably, a flushing water jet experiences no obstacle in the transition from the fastening line to the flushing distributor.
    The V-seal 40 comes in the assembled state of the flushing distribution system to lie around the connecting pipe 31 and between the toilet wall and shoulder 35 of the connecting pipe 31 to the inlet pipe 32. This prevents any water return between the rinsing distributor system and the sanitary articles.
    The toilet 5 comprises a bowl 50 with a bowl bottom 51, a substantially circumferential bowl wall 52 and a bowl top 53. The bowl top 53 is formed by a flat surface, the bowl except for a rear bowl area, the area for the rinse water supply, has a slightly inwardly projecting circumferential projection 530.
    In a rear area of the bowl 50, the area of the rinse water supply, the bowl 50 has an edge 531 projecting downwards into the bowl in the direction of the bowl bottom 51. This edge essentially covers the flushing distributor 10 of the flushing distributor device 1.
    [0093] The rear bowl wall area 520 has a wall opening 521 with a passage, into which the flushing distribution system 1 is introduced. The rinse distribution system 1 is oriented essentially horizontally, i.e. a central or longitudinal axis 602 of the system is introduced essentially horizontally in the toilet 5.
    The rinsing distributor 20 essentially consists of a T-piece, which has an outlet opening 11, 12, 13 at each of the three ends of the “T”. A rear side of the “T” is essentially formed by an inlet opening 15 and a peripheral edge 111. The edge 111 is not completely round, but straightened on two laterally opposite sides 1110, 1111. This allows a guided insertion of the edge into the rail 22 of the fastening line and a hold therein.
    The rinsing distributor 10 has an inlet opening 15 and three outlet openings 11, 12, 13, the third 13 of the three outlet openings being arranged on the side facing away from FIG. 3. A first outlet opening 12 points downward approximately parallel to the inside of the rear bowl wall region 520. The lower outlet opening is angled by approximately 20 degrees from the vertical, and therefore does not point exactly vertically downwards. A flushing water jet thus hits the inside of the bowl wall at a flat angle. The first outlet opening is arranged at an angle to the vertical 602 with respect to the central axis 601 of the fastening line 20 and the inlet opening 15. The two further outlet openings 11, 13 point radially outward in opposite directions. One of two further outlet openings 11, 13 points directly out of the plane of the drawing, the other into the plane of the drawing.
    The area which is completely open at the bottom between the rear bowl wall area 520 and bowl rim 531 allows direct access to the flushing distributor 10. Fastening means from the flushing distributor 10 and fastening line 20 allow the flushing distributor 10 to be removed by pulling it downward. The fastening line 20 is held in the wall opening 521 and on the rear bowl wall region 520. A first-time attachment or a subsequent reattachment of the flushing distributor 10 to the fastening line 20 from below is possible by inserting the edge 111 of the flushing distributor into the downwardly open rail 22 of the fastening line.
    A water pipe (not shown) is sealingly connected to the water feed pipe 30 from behind. The entire area of the rinse water supply and inlet into the toilet bowl is ceramic-free except for one bowl wall.
    Around the wall opening 521, the thickness of the wall is preferably slightly larger than in a lower region. In the example shown, the thickness of the wall around the wall opening 531 is approximately 15 mm. This range of thickness can extend over several centimeters. However, the wall opening 531 is located as high as possible in the toilet bowl and thus as close as possible to the top of the bowl 53 in order to allow water to flow in as far as possible from the top of the bowl. The thickness range around the wall opening 531 thus only extends over approximately 4 mm to 8 mm to the top of the bowl 53. Downward towards the bowl bottom 51, the thickness range extends over approximately 12 mm. On the side, the thickness range of 15mm extends over about 20mm.
    As can be seen in FIG. 5, the edge 111 of the flushing distributor 10 surrounding the inlet opening 15 is introduced into the rail 22, so that the edges 111, 220 of the flushing distributor and fastening line are flush below.
    Flushing distributor 10 and fastening line 20 are fastened to one another in FIG. 5. The flushing distributor is inserted from below with the edge 111 into the rail 22 of the fastening line 20. The flushing distributor 10 is removed from the fastening line 20 in the opposite direction.
    [0101] The rail 22 of the fastening line 20 is designed as a single continuous rail. An upper part is rounded, essentially following the outlet opening. The two sides are straight. The rail is horseshoe-shaped, as shown in Fig. 6. The upper round edge serves as a stop and positioning of the edge 111 of the flushing distributor 10. Edge 111 and rail 22 form mutually corresponding fastening means. On rail or edge
    CH 714 828 A2 alignment and insertion aids can be provided, for example beveled rail entrances. These make it easier to position the edge 111 on and in the rail when the edge is inserted.
    As can be seen in FIG. 3, the rear of the rail 22 simultaneously forms a stop for the fastening line on the toilet bowl wall when the fastening line is being installed.
    In the exemplary embodiment in FIG. 4, the tube 21 of the fastening line 20 has an external thread 210 over its entire length. This serves to connect the fastening line 20 to the water supply line and then to fasten it in the wall opening and the wall of a toilet.
    The external thread 210 extending over the entire length or even only over a large part of the length of the tube 21 enables the fastening line and the water supply line to be attached to walls of different thicknesses and to be securely fastened even if the ceramic walls are cast inaccurately.
    In Fig. 7, the rinse water supply and distribution area of Fig. 3 is shown enlarged. FIG. 7 shows a horizontal cross section through the flushing distributor area according to FIG. 3 at the level of the central axis 602. It can be clearly seen that the two lateral, opposite outlet openings 11, 13 in the flushing distributor 10 lie on a slightly curved line. The T-piece is slightly bent towards the inlet opening 521. A jet of rinse water is directed sideways and slightly backwards towards the wall.
    Due to the slight bend of the T-piece in the direction of the rear bowl wall, a rinse water jet on both sides of the rinse distributor 10 is directed laterally towards the inside of the rear bowl wall area 520, near the wall opening 521. This enables the inside to be wetted as completely and very broadly as possible the Wall.
    Except for the simple side wall with the wall opening 521, there is no further ceramic wall, ceramic tube or other ceramic element in the area of the flushing water supply and distribution. The toilet bowl is very simple in this area.
    1 to 3 and 7 roughly hatched areas are made of ceramic and part of the toilet bowl
    5. All ceramic elements are preferably cast together. The small areas are made of plastic.
    3 to 7 with water supply line 30 is suitable for replacing a flushing distributor construction and a ceramic water inlet in a conventional toilet. Such a toilet can be manufactured with significantly less effort and less ceramic mass than conventional toilets. Such a toilet, in particular a rinsing distributor, can also be cleaned better.
    The terms “below” and “above” are used in relation to the objects shown in the figures. However, the flushing distribution system is shown as it would be in the room when assembled.
    [0111] Accordingly, “below” and “above” are understood in particular with regard to WC. "Bottom" also refers to a general flow direction of water due to gravity.
    Exemplary dimensions of the toilet bowl according to FIG. 3 are:
    Wall opening diameter:> 46mm; Wall thickness around wall opening: 15 mm;
    Distance from wall opening to inside edge at height of central axis:> 36 mm.
