EP3543412B1 - Flushing distributor system for sanitary articles and sanitary articles with such a flushing distributor system - Google Patents

Description

The invention relates to the field of flush distributor systems for sanitary articles, in particular for those made of ceramics, for example toilets. Typically, toilet bowls are made of ceramic. The bowl itself, as well as the water inlet and flushing distributor for flushing 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. Water inlet and flushing manifold areas are also difficult or impossible to access for cleaning or decalcification. Generic purge manifold systems are in DE 10 2006 031 893 A and EP 0 643 177 A disclosed.

There is therefore a need to create a flushing distributor system for sanitary articles, in particular toilets, which makes cleaning easier. The invention includes a plastic flush manifold system for use with a sanitary article such as a toilet or urinal. The flush manifold system includes a flush manifold and an attachment line for attaching the flush manifold to a sanitary article. The flushing distributor has an inlet opening, at least one outlet opening arranged at an angle to the inlet opening, and fastening means. A central axis of the inlet port of the purge manifold corresponds to a central axis of the attachment line.

The fastening means of the flushing distributor are preferably arranged in the outer area of the inlet opening. The inlet opening is preferably fully accessible. The attachment line also has attachment means, which attachment means of the attachment line correspond to the attachment means of the flushing manifold, for detachably attaching the flushing manifold to the attachment line. The attachment means of the flushing distributor and attachment line are arranged and designed in such a way that they can be removed and permit attachment of the flushing manifold to and from the attachment conduit in a direction perpendicular to the central axis of the attachment conduit. A flushing manifold system in which the flushing manifold and attachment line are detachable from one another allows easy cleaning or replacement of the flushing manifold. The mounting line can be mounted in a plumbing fixture and the flush manifold can be attached to and removed from the mounting tubing as needed, particularly after installation of the plumbing fixture. After removing the flushing distributor, cleaning in the area of the attachment line is also possible. In particular, a decrease

Attachment and detachment of the flush manifold in a direction perpendicular to a central axis of the attachment pipe also enables detachable attachment of a flush manifold in a toilet where a ceramic rim makes access to a flush water inlet impossible. The direction perpendicular to the central axis preferably corresponds to a direction downwards or from below in relation to the sanitary item, for example the rim of a toilet bowl. A flushing distributor system made of plastic also makes it easier to produce a sanitary item. In particular, it allows the replacement of ceramic parts that make up a flushing manifold. For example, a mold can be simplified and ceramic can be saved. This means that a sanitary article that is otherwise of the same design can be produced more easily and with less weight. It is also comparatively easy to comply with tolerances in the production of plastic elements, so that a regular, consistent flushing result can be achieved. Tolerances in the production of a ceramic sanitary article can also be compensated for with the flushing distributor system made of plastic.

'Perpendicular to the central axis' of the fastening line is understood to mean a direction of 90 degrees to the central axis. However, 'perpendicular to central axis' includes exactly 90 degrees with respect to the direction of removal and attachment of the flushing manifold, as well as a few degrees of deviation from exactly 90 degrees. For example, depending on the configuration of the fastening means, they can be tilted or slightly angled relative to the central axis of the fastening line. 'Perpendicular to the central axis' thus also includes directions which deviate by up to 20 degrees from the vertical of the central axis of the fastening line.

Fastening means of the scavenging distributor and fastening line are preferably designed in such a way that the scavenging distributor can be removed from or attached to the fastening line by moving in a direction exactly 90 degrees perpendicular to the central axis of the fastening line.

The central axis of the attachment line generally corresponds to the longitudinal axis of the line part of the attachment line.

In the flushing distributor system according to the invention, the attachment means of the flushing distributor and fixing line, and the at least one outlet opening of the flushing distributor are preferably designed and arranged in such a way that they allow the flushing distributor to be removed from and attached to the fixing line essentially in one direction of the at least one outlet opening of 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 in a sanitary article, it points in the direction of the outlet of the sanitary article or in the direction of a bowl bottom. However, this direction typically points neither exactly vertically downwards nor exactly perpendicularly to the central axis of the fastening system, but rather deviates from the vertical. This allows the flushing water to be directed through the outlet opening of the flushing distributor not vertically downwards, but rather parallel to an inner wall of the bowl or in the direction of the outlet of the sanitary article. 'Substantially' in the direction of the outlet opening thus includes a deviation of, for example, up to 45 degrees from the vertical.

To attach the flushing distributor to the attachment line, the attachment means are connected to one another. To remove the flushing manifold from the attachment line, the attachment means are detached from one another.

The attachment means of the flushing distributor and the attachment line are preferably designed in such a way that the attachment means can be connected and released by a relative movement of the flushing distributor and attachment line. Preferably, no tools whatsoever are required for connecting and loosening the fastening means.

Connecting and disconnecting of the fastening means can be effected by a linear movement or by a rotational movement or by a combination of a linear and rotational movement. Linear and rotary movements can also be combined. For example, the fastening means can be released initially by a rotational movement, with the flushing distributor then being removed by a linear movement perpendicular to the central axis of the fastening line.

The attachment means of the flushing distributor and the attachment line preferably allow the attachment means to be loosened and connected and the flushing distributor to be removed and attached by a linear relative movement, for example an exclusively linear relative movement of the flushing distributor and attachment line.

Preferably, the attachment means of the flushing manifold and attachment line are arranged and configured to allow removal and attachment of the flushing manifold from and to the attachment line by a purely linear movement in the direction perpendicular to the central axis of the attachment line.

In preferred embodiments of the flushing distributor system, the attachment means of the flushing distributor and the attachment line are designed as mutually corresponding interlocking grooves and ridges. can the fastening means of the fastening line can be designed as a rail and the fastening means of the flushing distributor can be designed as a comb or longitudinal projection which is guided in the rail of the fastening line. The comb and rail can also be attached to the other element of the flushing manifold system. A comb of the attachment line is then routed into a groove or rail of the flushing manifold, thereby attaching the two elements together.

Preferably, the attachment conduit has a horseshoe shaped rail and the flushing manifold has a rim projecting around the inlet opening.

Alignment and insertion aids can be provided on the flushing distributor and attachment line. These enable easier positioning of the fastening means relative to one another and preferably simplify the fastening process, for example mutual guiding, such as inserting a comb in a groove.

The attachment means of the flushing distributor and attachment line can also form a snap lock. For example, the flushing manifold and attachment line can be provided with slightly offset projections that snap into place when the flushing manifold and attachment line are fully connected. A snap fastener can also be configured in other ways, such as an interlocking projection and notch.

A snap lock can preferably be released with slightly increased effort. A snap lock preferably prevents the fastening means from being loosened unintentionally, for example due to flushing water pressure or vibrations.

The attachment 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 which correspond to the fastening means of the flushing distributor are preferably attached to one end of the pipe part. The fastening line preferably has a radially outwardly projecting stop at this one end. In the installed state of the flushing distributor, the stop can limit a movement of the fastening line or the flushing distributor system in a wall opening in a wall of a sanitary article, at least in one direction.

The stop can be formed by the fastening means or as a separate stop, for example a radially outwardly protruding projection.

The stop is preferably formed by the fastening means. For example, a rear side of a fastener forms a stop, while a front side of the fastener corresponds to the fasteners of the flushing manifold.

The purge manifold has at least one outlet port. If only a single outlet opening is provided, this preferably not only points in a single direction, but rather allows flushing water to be distributed in several directions. The outlet opening can be designed, for example, as an elongate outlet opening, for example as a curved slit. A single outlet opening preferably enables flushing water to be distributed in a fan shape. Flushing water is thus directed not only in a downward direction, for example, in the direction of the outlet of a sanitary article, but also allows a wide lateral wetting and washing off of an inner wall of the sanitary article.

Preferably, a plurality of outlet openings are provided in the flushing manifold. If there are several outlet openings, these are arranged in different areas of the flushing distributor and preferably point in different directions. Flushing water can thus be directed through the multiple outlet openings into different areas of an inner wall of the sanitary article.

In preferred embodiments of the flushing distributor, the flushing distributor has three outlet openings. A first of the three outlet openings is preferably perpendicular to a second and third outlet opening of the three outlet openings arranged. The second and third outlet openings are preferably in line and allow the flushing water to be distributed in substantially opposite directions. A flushing manifold having three outlet ports is preferably formed as a T-piece, with one side of the T-piece having the inlet port. This is preferably arranged perpendicularly to all the outlet openings, so that a jet of flushing water enters the flushing distributor through the inlet opening and is then prevented from flowing further in a straight line by a wall of the T-piece. The flushing water is distributed through the outlet openings which are arranged at an angle, for example arranged perpendicular to a central axis of the inlet opening.

Preferably, a central axis of the inlet opening of the flushing manifold corresponds to the central axis of the attachment line.

The flushing distributor system according to the invention can also have a safety part. The securing part can be attached to an end of the fastening line opposite the flushing distributor. The securing part has larger external dimensions than the fastening line. The fastening line can thus be secured at least in one direction against falling out of a wall opening of a sanitary article when the fastening line is inserted in this wall opening, for example in a wall of a toilet bowl.

With a stop and a securing part, the flushing manifold system can be firmly mounted on a sanitary article.

With a safety part, a ceramic water inlet of a toilet bowl can be connected to a water connection pipe, as is known, regardless of the differently designed flushing distributor system.

As an alternative to a safety part, the flushing distributor system can have a plastic water supply line. The water supply pipe is connected at one end to the attachment pipe and at its opposite end End can be connected to a water connection pipe. The water inlet line replaces a water inlet, which is an integral part of the ceramic bowl in standard toilets and is connected to a water connection pipe.

In the case of a flushing distributor system in which a water supply line made of plastic is also provided, the production of a sanitary article is further simplified. In particular, it enables the further replacement of ceramic parts. A ceramic water inlet can also be replaced by the water inlet pipe. A sanitary article in the region of the flushing distributor is thus preferably essentially restricted to a wall opening in a bowl wall. A mold can be greatly simplified and additional ceramics and weight can be saved.

A connection to a water pipe, which is usually a pipe made of plastic but can also be made of metal, is also improved. Usually the end of the pipe of the water pipe is pushed into the ceramic inlet to form a seal. Such a connection is highly susceptible to leaks, in particular also due to the generous tolerances of the inside diameter of the ceramic water inlet.

In contrast, the connection of a pipe end to or into a plastic supply line can be implemented very easily, for example with a union nut. Plastic connections can be assembled very tightly and are not prone to leakage. In addition, plastic water supply lines and metal pipes have lower tolerances, which simplifies the creation of standardized connections.

With the water supply line, another element of the flushing water supply in a sanitary item can be produced with few deviations. This has a positive effect on a regular, consistent flushing result.

Fastening line and water supply line can be permanently or detachably connected to each other. They can also be used as a common part getting produced. Fastening line and water supply line are preferably separate elements which are screwed together.

Threaded plastic items are easy and inexpensive to manufacture and also form a secure and tight connection.

Preferably, the attachment line has an external thread and the water supply line has an internal thread that corresponds to the external thread of the attachment line. Reversed threads or other types of attachment are also possible. For example, a water supply line can also be connected to the fastening line by means of a bayonet lock, by means of a snap lock or by means of clamps.

A water supply line is preferably tubular, with different diameters being able to 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 pipe preferably has a standardized diameter, for example EN80.

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.

A longitudinal axis of the first line section preferably corresponds to the central axis of the fastening line.

The two line sections of the water supply line are preferably arranged coaxially. Then the longitudinal axis of the water supply line corresponds to the central axis of the attachment line.

The elements of the flushing manifold system can be multi-piece or one-piece. Preferably, the flushing distributor, attachment line or water supply line are in one piece. Preferably, the flushing manifold, attachment line and water supply line are in one piece.

The purge manifold system is made of plastic, for example injection molded plastic. The plastic used should be chemically resistant and mechanically strong enough for assembly and multiple connection and disconnection of the individual elements of the flushing distributor system. Polypropylene (PP) is preferably used to manufacture the flushing manifold.

Unless explicitly stated otherwise, all openings in the flushing distributor system preferably have a round inner diameter. Other diameter shapes, for example elliptical, are also advantageous in terms of even water distribution or optimized cleaning. However, diameters other than round are also possible, for example square or polygonal diameters.

The purge manifold system may further include a flow restrictor. This can be placed in any element of the flushing manifold system. A flow restrictor is preferably located upstream of the inlet port of the purge manifold. A flow limiter is preferably introduced in the fastening line.

The invention also includes a sanitary article with a flushing manifold system according to the invention and described in the application. The sanitary article is preferably a toilet. The sanitary article is preferably made of ceramic, for example cast completely from ceramic.

In preferred embodiments, the sanitary article has a bowl with a wall opening made in an upper region of a rear bowl wall section. The attachment line of The flushing distributor system is placed in the wall opening and the at least one outlet opening of the flushing distributor attached to the fastening line points in the direction of the bottom of the bowl. The flushing distributor system is introduced and aligned in the wall opening in such a way that flushing water guided through the flushing distributor is directed along the inside of the rear bowl wall section at least in the direction of the bowl bottom. Lateral areas of the inner wall are preferably also wetted.

Preferably, the bowl has at least in the area of the wall opening, preferably exclusively in the area of the wall opening, an edge that protrudes into the interior of the bowl in the direction of the bowl bottom and is spaced apart from the rear bowl wall section. A hollow volume formed by the rim, a bowl top and the rear bowl wall section is completely open in the direction of the bowl bottom.

This allows easy and direct access to the flush manifold. The open area between the edge and the rear bowl wall section not only simplifies the removal of the flushing distributor, it actually makes it possible in the first place. In addition, as already mentioned above, a bowl can have a much simpler shape than with a flushing distributor integrated into the ceramic bowl.

In preferred embodiments of the flushing manifold system, this also has a water supply line. A sanitary item can be designed very simply in the area of the flushing distributor and the water inlet. A bowl wall essentially has only one wall opening for attachment of the flush manifold system. The attachment line of the flushing distributor system is positioned in the wall opening of the bowl wall. Depending on the configuration of the flushing distributor system, the water supply line is mounted on one end of the fastening line on the rear side of the wall. The flushing distributor is attached to the inside of the bowl at the opposite end of the attachment line and via the corresponding attachment means detachably attached to the attachment line. Optionally, the water supply line is already connected to the attachment line or made as a common element.

The flush manifold system is preferably retained 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 gaskets can additionally be provided for sealing the flushing manifold system.

A rear bowl wall section in the area of the wall opening therefore has no additional ceramic projections or tubular inflow parts. Correspondingly, a bowl wall around the wall opening can have a thickness that is as uniform as possible.

A rear bowl wall section adjacent the wall opening preferably has a thickness equal to or less than 25 millimeters, more preferably equal to or less than 20 millimeters, for example a thickness between 10 millimeters and 20 millimeters or between 12 millimeters and 18 millimeters, such as 15 millimeters.

Depending on the position of the wall opening in the bowl wall, a thickness of the bowl wall that is as uniform as possible extends around the wall opening over a more or less extensive area. A wall opening in the bowl wall is preferably arranged as close as possible to a bowl top.

The thickness of the bowl wall around the wall opening, which is as uniform as possible, preferably extends over at least 3 millimeters, particularly preferably over at least 5 millimeters around the wall opening.

The extension of the most uniform possible thickness of the wall opening is limited in the upward direction by the top of the bowl. The rear one, which is adjacent to the wall opening, points downwards towards the bottom of the bowl Bowl wall section at least over a length of preferably 10 millimeters, particularly preferably over a length of at least 15 millimeters in the direction of the bowl bottom, a thickness of less than or equal to 25 millimeters, particularly preferably equal to or less than 20 millimeters, for example a thickness between 10 millimeters and 20 millimeters or between 12 millimeters and 18 millimeters.

The invention also includes a ceramic toilet having a bowl with a wall opening made in an upper region of a rear bowl wall section for the introduction of a flushing distribution system according to the present invention and as described in the application. At least in the area of the wall opening, preferably exclusively in the area of the wall opening, the bowl has an edge which protrudes into the interior of the bowl in the direction of the bowl bottom and is spaced apart from the rear bowl wall section. A hollow volume formed by the rim, a bowl top and the rear bowl wall section is completely open in the direction of the bowl bottom. The rear bowl wall section adjoining the wall opening also has a thickness of less than or equal to 25 millimeters, preferably of less than or equal to 15 millimeters.

The other features and advantages of such a ceramic toilet bowl have already been described in connection with the flushing distribution system and generally in relation to sanitary articles.

In the figures, the same reference symbols are used for the same or similar elements.

The flush manifold system 1 in 1 consists of a flushing distributor 10 and a fastening line 20 made of plastic, for example PP. The attachment line 20 is a tube 21 which has a radially projecting edge 220 at one end. Apart from a lower area, the edge 220 is configured as a rail 22 that is accessible from below.

An edge 111 of the flushing distributor 10 running around an inlet opening 15 is introduced into the rail 22 so that the edges 111, 220 of the flushing distributor and fastening line are flush at the bottom.

Flushing manifold 10 and attachment line 20 are in 1 attached to each other. In 2 flushing manifold 10 and attachment line 20 are shown separated from each other. Arrow 600 indicates the direction in which the purge manifold 10 with the Fastening line 20 is connected. The rinsing distributor is pushed into the rail 22 of the fastening line 20 from below with the edge 111 . The flushing distributor 10 is removed from the fastening line 20 in the opposite direction.

The flushing 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 the figure. A first outlet opening 12 points downwards and is arranged at an angle to the vertical 602 in relation to the central axis 601 of the fastening line 20 and the inlet opening 15 . The two other outlet openings 11, 13 point radially outwards in opposite directions. The flushing distributor 20 consists essentially of a T-piece 14, which has an outlet opening 11,12,13 at each of the three ends of the "T". this is in 3 clearly visible in the front view of the flushing manifold. A back side of the "T" is essentially formed by the inlet opening 15 and the peripheral edge 111. FIG. The edge 111 is not completely round, but straightened on two laterally opposite sides 1110,1111. This allows the rim to be guidedly inserted and retained in the track 22 of the fastening line.

The rail 22 of the attachment line 20 is designed as a single continuous rail. An upper part is rounded, essentially following the exit opening. The two sides are straight. The rail is designed in a horseshoe shape, as in 4 shown. 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 fastening means that correspond to one another. Alignment and insertion aids can be provided on the rail or edge, for example bevelled rail entrances. These allow easier positioning of the rim 111 on and in the splint when inserting the rim. As in 2 to see the back of the rail 22 forms at the same time a stop for the attachment line, for example on a toilet bowl wall, when mounting the attachment line.

The inlet opening 23 and outlet opening 24 of the attachment line 20 have the same inner diameter as the inlet opening 15 of the flushing distributor 10. Preferably, a jet of flushing water does not experience any obstacles in the transition from the attachment line to the flushing distributor.

The tube 21 of the attachment line 20 has in the embodiment of figure 1 an external thread 210 over its entire length. This is used to attach the attachment line 20 in a wall opening and a wall of a sanitary article. By means of an external thread 210, for example, a threaded nut or another securing element (not shown) can be attached to the end of the fastening line 20 opposite the flushing distributor 10 and the fastening line can thus be fastened to the wall.

The external thread 210 running over the entire length or just over a large part of the length of the tube 21 enables the fastening line to be attached to walls of different thicknesses and secure fastening even with imprecisely cast ceramic walls.

The flushing distributor system according to Figures 1 to 4 is suitable to replace a ceramic flush distributor construction in a conventional toilet. Such a toilet can be manufactured correspondingly more easily and the flush distributor can be cleaned.

The terms 'bottom' and 'top' are used with respect to the items depicted in the figures. However, the purge manifold system is shown as it would be oriented in space when assembled. Correspondingly, “below” and “above” are understood in particular with regard to sanitary articles. 'Down' also refers to a general direction of flow of water due to gravity.

In 5 and 6 the flushing manifold system is shown in cross section with water supply line 30 . figure 5 shows the system in an exploded view and 6 in assembled condition.

Flush manifold 10 and attachment line 20 are the same as described in the previous figures. In addition, the flushing manifold system includes a water supply line 30 and a V-seal 40 . The water supply line 30 consists essentially of a supply pipe 32 and a connecting pipe 31 coaxially adjoining it. The connecting pipe 31 has an internal thread 310 along its entire length. The internal thread 310 and the internal diameter of the connecting pipe 31 correspond to the external thread 210 and external 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 pipe 30 has a larger internal diameter than the connecting pipe 31 and also than 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 manifold 10, as in 6 is good to see.

The upstream end 33 of the inlet pipe 32 is sealed to a water line (not shown). Water line and inlet pipe are preferably standardized.

The V-seal 40 comes to rest around the connecting pipe 31 and between the wall of the sanitary article (not shown) and the shoulder 35 of the connecting pipe 31/inlet pipe 32 when the flushing distributor system is in the assembled state. This prevents any water running back between the flushing distributor system and the sanitary items.

• Innendurchmesser Zulaufrohr: >55 mm;
• Aussendurchmesser Verbindungsrohr: 45mm;
• Innendurchmesser Befestigungsleitung: 35 mm;
• Winkel Senkrechte zur Mittelachse - untere Auslauföffnung Spülverteiler: 10Grad bis 25 Grad, beispielsweise 15 Grad bis 20 Grad;
• Winkelabweichung seitliche Auslauföffnungen Spülverteiler von Geraden durch beide Öffnungen: 3 Grad bis 10 Grad, beispielsweise 5 Grad;
• Durchmesser untere Auslauföffnung: 10 mm bis15 mm, beispielsweise 13 mm; Durchmesser seitliche Auslauföffnungen: 18 mm bis 22 mm, beispielsweise 20mm.

Exemplary dimensions of the flushing distributor system are:

• Inside diameter of inlet pipe: >55 mm;
• Outer diameter connecting tube: 45mm;
• Inside diameter of fastening line: 35 mm;
• Angle perpendicular to central axis - lower outlet flushing manifold: 10 degrees to 25 degrees, for example 15 degrees to 20 degrees;
• Angular deviation of side outlet openings flushing manifold from straight lines through both openings: 3 degrees to 10 degrees, for example 5 degrees;
• Lower outlet opening diameter: 10 mm to 15 mm, for example 13 mm; Diameter of lateral outlet openings: 18 mm to 22 mm, for example 20 mm.

In 7 , 8 and 9 12 are a rear view, a bottom view, and a top view, respectively, of the flushing manifold system of FIGS 6 shown. In 8 and 9 It can be 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 bent slightly backwards towards the inlet opening. This directs a jet of flushing water sideways, but slightly backwards towards the wall. This allows a very wide wetting of the inside of the wall.

The flushing distributor system 1 according to Figures 5 to 9 with water inlet pipe 30 is suitable for replacing a flush manifold construction and a ceramic water inlet in a conventional toilet. Such a toilet can be produced with significantly less effort and less ceramic material than conventional toilets.

• Durchmesser Wandöffnung: >46mm; Wanddicke um Wandöffnung: 15 mm;
• Distanz Wandöffnung-Randinnenseite auf Höhe Mittelachse: >36 mm.

Exemplary dimensions of the toilet bowl 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.

10 shows a WC 5 with a built-in flushing distributor system 1 according to FIG 6 but without V-seal. The toilet 5 includes 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, with the bowl having a slightly inwardly projecting peripheral projection 530 except for a rear bowl area, the area for flushing water supply.

In a rear area of the bowl 50, the area of the rinsing water supply, the bowl 50 has an edge 531 projecting downwards into the bowl in the direction of the bowl bottom 51. This rim essentially covers the flushing manifold 10 of the flushing manifold device 1.

The rear bowl wall area 520 has a wall opening 521 into which the flushing distributor system 1 is introduced. The flush distributor system 1 is aligned essentially horizontally, i.e. a central or longitudinal axis 602 of the system is placed in the toilet 5 essentially horizontally.

The lower outlet opening 12 of the flushing distributor 10 points downwards approximately parallel to the inside of the rear bowl wall region 520. The lower outlet opening is angled at approximately 20 degrees from the vertical and thus does not point exactly vertically downwards. A jet of flushing water thus hits the inside of the bowl wall at a shallow angle. One of the two other outlet openings 11,13 points directly out of the plane of the drawing, the other into the plane of the drawing.

The area between the rear bowl wall area 520 and the bowl edge 531, which is completely open at the bottom, allows direct access to the flushing distributor 10. The attachment means of the flushing distributor 10 and attachment line 20 allow the flushing distributor 10 to be removed by pulling the same downwards. The attachment line 20 is retained in the wall opening 521 and on the rear bowl wall area 520 . This makes it possible to subsequently reattach the flushing distributor 10 from below to the fastening line 20 by pushing the edge 111 of the flushing distributor into the rail 22 of the fastening line, which rail is open at the bottom.

A water pipe (not shown) is sealed to the water supply pipe 30 from behind. The entire area of the flush water supply and inlet into the toilet bowl is ceramic-free except for one bowl wall. From a purely technical point of view, a rim 531 could also be dispensed with, since the flush distributor 10 takes over the entire water distribution in the toilet bowl. For optical and design reasons, however, people are reluctant to do without an edge.

Around the wall opening 521, the thickness of the wall is preferably slightly greater than in a lower or more lateral area. In the example shown, the thickness of the wall around the wall opening 531 is approximately 15 mm. This thickness range 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 upper side 53 of the bowl in order to allow water to flow in from the top of the bowl if possible. The same thickness range around the wall opening 531 thus only extends over approximately 4 mm to 8 mm up to the bowl top 53. The same thickness range extends downwards towards the bowl bottom 51 over approximately 12 mm. On the side, the thickness ranges from 15mm to about 20mm.

In 11 and 12 the rinse water supply and distribution area is shown enlarged. 11 FIG. 1 shows a horizontal cross-section through the flushing manifold area according to FIG 10 at the level of the central axis 602. 12 shows a vertical cross-section through the flushing manifold area according to FIG 10 essentially through the T-piece 14 of the flushing distributor 10 centrally to the lateral outlet openings 11,13.

11 12 clearly shows the alignment of the two lateral, opposite outlet openings 11, 13 in the flushing distributor 10 and that these lie on a line that is slightly bent backwards. The T-piece 14 is bent slightly backwards towards the rear bowl wall. A jet of flushing water is thus directed laterally on both sides of the flushing distributor 10 onto the inside of the rear bowl wall region 520, specifically as close as possible to the wall opening 521. This enables the inside of the wall to be wetted as completely and as widely as possible. 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. The in the Figures 10 to 12 Roughly hatched areas are made of ceramic and are part of the toilet bowl 5. All ceramic elements are preferably cast in one piece. The small shaded areas are made of plastic and are part of the flushing distributor system 1.
