Description

Toilet with flushing water connection

Technical Field

The invention relates to a toilet with water flushing, abbreviated as WC, which accordingly has a flushing water connection. The invention also relates to the use of such a toilet.

Background

Toilets have long been of standard configuration and are widely used. Depending on their function, they have a connection for flushing water from a flushing water supply, for example a flushing water tank or a flushing water pipe without a flushing water tank but with a flushing valve. The vertical pipe section extends from the flush tank down to a so-called flush elbow in which the pipe direction is changed by about 90 degrees in relation to the toilet bowl direction. If there is no flush tank, the corresponding flush water pipe can run, for example, horizontally in the wall behind the toilet and can likewise be reached via a flush elbow (i.e. a corner fitting).

The toilet consists essentially of a toilet body, usually made of ceramic. The toilet body typically has a rear portion through which the toilet body moves towards the mounting wall. In the case of a hanging installation, the toilet body is hung on a wall with its rear part; but it may also have its own stand. The connection is usually made through the rear, for which purpose the toilet body has at the rear a corresponding connection for the flushing water, and of course also for the sewage. The installer connects these connections, which are usually integrated in the ceramic body, via pipe sections cut out as required, for example to flushing elbows and wall-side sewage connections, i.e. to the inlet to the sewage treatment system.

The flushing water delivered by the flushing water connection is usually distributed along the flushing rim into the toilet bowl. The flushing rim is here designed to hang inwardly along the upper rim of the toilet bowl and to distribute the flushing water via a number of downward openings like a shower head.

In recent years, toilets provided with a single (or several) flushing water inlet (or several such openings) on the side wall of the toilet bowl, which introduces flushing water substantially horizontally and along the inner wall of the toilet bowl, have been increasingly put on the market. Such a washing water inlet is usually not provided at the rear, but at the side.

In such toilets, the flushing water is usually led along a curved pipe bend to a flushing water inlet, which may be formed integrally with the toilet body and which, like the conventional toilets described above, extends all the way to the rear of the toilet, i.e. to a connection on the wall.

Here "behind" refers to a direction pointing backwards from the perspective of a user sitting on the toilet, i.e. behind him and pointing towards a wall. Similarly, "front" corresponds to the direction of the user's line of sight directly in front. "lateral" and "width direction" are also understood to mean, from the perspective of the user, to the right or to the left or in the direction of the shoulders of the user. This applies to the rest of the description and claims.

Disclosure of Invention

The object of the invention is to propose a toilet with an improved flushing water connection.

The object of the invention is achieved by a toilet bowl comprising: a toilet body, a toilet bowl in the toilet body, a flushing water inlet in the toilet body and the toilet bowl, a pipe integrated in the toilet body between the flushing water inlet of the toilet and a flushing water connection, wherein the flushing water connection is arranged behind the toilet bowl and at least 5cm from the rear side of the toilet body. The invention also relates to an advantageous use of the toilet.

Preferred embodiments are given in the dependent claims and will be explained in detail below together with the basic idea of the invention. No distinction is made between the individual protection types.

The basic idea of the invention is: leaving an intermediate distance between the integrated flush water connection of the toilet and the rear of the toilet body. The distance is at least 5cm, preferably at least 6cm, 7cm, 8cm, 9cm or even 10 cm.

The flushing water connection is a connection on the toilet body itself, i.e. on a pipe section which is integrated into the toilet body on one side and which extends from the flushing water connection to the flushing water inlet (in the toilet bowl) on the other side.

This distance according to the invention can be bridged across the respective pipe section when connected, as will be explained in more detail below. The conduit section is not integral with the toilet body and may be made of different materials. With respect to the toilet body itself, the flush water connection is preferably not connected to the rear of the toilet body.

This is particularly applicable to toilets with additional functionality, particularly shower-toilets, which is the preferred application here. Between the rear of the toilet bowl itself and the rear of the toilet body and/or above this area, a certain number of technical devices for shower functions and other functions should be placed, so the distance between the rear of the toilet bowl and the rear of the toilet body is usually larger than for a simple toilet without additional functions.

Preferably, the toilet body is made of ceramic. The pipe section can be made of plastic, for example. In the ceramic design of the toilet body, the pipe between the flushing water inlet and the flushing water connection can be integrally formed by a so-called hollow casting process.

"integrated" means fabricated from the same materials and with a uniform fabrication process. In this case, there is usually no visible border or material transition.

In the manufacture of ceramic toilet bodies, which have ceramic pipes for flushing water extending to the rear of the toilet body in a conventional manner, corresponding connections are usually connected to other ceramic components of the rear, in particular to the frame of the toilet body. The inventors herein have found that the number of cracks increases, which may be caused during the ceramic production process (including firing and drying) or due to mechanical stress caused by the weight of the user. It has been demonstrated that: in any case, the pipe section for the flushing water would in some way form a "lever" for force transmission to the rear of the toilet body, which would be problematic.

On the other hand, if the duct were to be extended to the rear without such mechanical connection, a relatively long and "unsupported" duct section would be formed, which in turn would be susceptible to breakage or breakage.

In addition, the pipe section, whether made of plastic or ceramic, unnecessarily complicates the manufacture of the toilet body.

In addition, it has been confirmed that: the bridging can be achieved in a very simple manner by the pipe sections (preferably made of plastic) required for the distance and with various advantages as will be explained below.

The invention is particularly suitable for toilets mentioned at the outset which do not have a conventional flushing rim, but have a lateral flushing water inlet in the toilet bowl. The pipe bends connecting the flushing water inlets with the flushing water connections can here be made integrally with the toilet body, in particular in ceramics, in particular in the mentioned hollow casting process. Along the length of the pipe bend, there are no further transitions between the individual parts, whose abrupt diameter changes, glue joints, seals or similar elements can impede the flow, form attachments that can cause contamination problems, increase manufacturing costs, contain a risk of leakage and/or complicate assembly.

Here, the flushing water connection (and very generally in the present invention) is preferably centered with respect to the width direction, i.e. centered behind the toilet bowl. In the case of the pipe bend just described, it leads not only to the rear of the toilet bowl, but also to the area behind its center, see the examples.

According to the invention, the flushing water connection itself can have a circular cross-section, even for pipe bends which normally have a non-circular (for example oval) cross-section. Conventional connection techniques can thus be used, in particular a round joint on the flushing water connection of the toilet and an insertion tube end with a conventional seal. In the past, the adhesion is adopted for the non-circular cross section, which is relatively complex and has poor reliability.

Another advantage that can be achieved by the present invention is: by designing the pipe section to be connected to (or to) the flushing water connection of the toilet relatively long, the individual parts required on the pipe connection or pipe section are reduced. The pipe section can then, during installation, extend back out of the toilet body and be connected to the flushing water supply in the interior of the wall, i.e. behind the front side of the wall. For example, it may be attached directly to the flushing elbow. Conventionally, if the pipe portion integrally formed with the toilet main body does not reach the rear of the toilet in any way, particularly if a curved pipe bend is not integrally formed along the toilet bowl, the pipe bend is made of plastic, for example. From the flushing elbow a straight pipe section is led forward and cut to length appropriately. On the other hand, the number of pipe sections and the number of transitions can also be reduced by making the pipe sections to be connected to the (integrated) flushing water connections of the toilet penetrate into the wall.

A further advantageous application of the invention is the height adjustability of the connection to the flushing water. This can be achieved, for example, by selecting between a plurality of differently formed pipe sections. Thereby, the height difference can be compensated for according to individual situations. Mechanical fastening, such as slotted holes, can be used if the toilet itself is mounted at a height that can be selected within a certain range of adjustment. In many cases, the sewage connection is already height-adjustable on the wall side or can be realized height-adjustably like a rinsing water connection.

Furthermore, the pipe section can have a connection opening on its outer surface, which can be used in different ways. For this purpose, it is generally possible to provide the connection opening with a screwable cap. This connection opening can then be used, for example, for installing a flushing water throttle valve. Such a flushing water throttle valve makes it possible to adjust the inflow of flushing water on a case-by-case basis if the inflow of flushing water with too much kinetic energy is possible due to a certain predetermined height difference relative to the tank or a certain predetermined pipe pressure. This is particularly advantageous in particular for toilets in which a plurality of the mentioned lateral flushing water inlets already exist in the bowl, in particular in order to prevent splashing. For a description of this, reference is made to patent document EP3064663a 1.

Alternatively (or additionally, for example with an additional connection opening), an odour removal device can be connected in order to remove unpleasant odours from the toilet bowl via the flush water line. Finally, an additive can be added, for example, a device for introducing a cleaning or sanitizing agent (e.g., a tablet), such as a cage, can be inserted through the connection opening.

Another advantage of the present invention is: the pipe sections in the rear region of the toilet are thinner than the corresponding ceramic pipe sections due to their plastic design, thus saving valuable space. This space may be used, for example, for mounting shower assemblies. In this case, there is also an advantage that: first, the pipe sections are omitted during assembly and only inserted after the shower assembly has been fully installed. In particular cases, this may create valuable "adjustment space (Rangierraum)" for the installation of other parts.

Detailed Description

In fig. 1, a ceramic toilet body is denoted by reference numeral 1, the toilet body 1 having an opening for a toilet bowl 2 visible from the front and an opening 3 for mounting a shower assembly visible from the rear. The depression numbered 4 serves to pass a shower arm of a shower device, not shown here, which is likewise not shown here. At its rear right side, a rinsing water connection 5 is visible, which is connected to a pipe section 6. The following 7 shows a pipe section for the sewage connection 14. The pipe sections 6, 6', 7' are made of plastic.

The same can be seen in fig. 2, but in which a straight-running pipe section 6' is depicted, whereas the pipe section 6 in fig. 1 forms a small height jump. Fig. 3 shows the height jump caused by the pipe section 6 and the inner shape of the basin in longitudinal section.

The advantage of the jump in height here is that the relatively low position of the rinsing water connection due to the sink 4 for the shower arm is compensated. Thus, the pipe section 7 is straight. According to fig. 2 (and fig. 4), the toilet is installed correspondingly high.

Fig. 4 shows two longitudinal sections which are arranged next to one another at the same height, wherein the viewing direction on the right corresponds to fig. 3, but pipe sections 6 'and 7' according to fig. 2 are used. The pipe sections are omitted from the left side and the connections can be seen. In particular, a rinsing water inlet 8 can be seen here, which communicates with the rinsing water connection 5.

Fig. 5 shows a cross section of the toilet bowl main body 1 in fig. 1 to 4, but in the width direction (perpendicular to the plane of the cross section) and rearward in the viewing direction. Here, in particular, the pipe bend 9, which establishes the connection on the right side, can be seen. The pipe elbow 9 is integrally formed with the ceramic toilet main body using a hollow casting process. Here it extends out of sight inside the envelope wall 10 and the basin inner wall 11.

That is to say that during the flushing process the flushing water is passed directly (without intermediate pieces) from the concealed cistern, not shown, through the flushing elbow, also not shown, into the pipe section 6 or 6 'and via the pipe section 6 or 6' and the flushing water connection 5 into the pipe elbow 9, so that it enters the basin 2 through the flushing water inlet opening 8. In the basin 2, the washing water performs a circular and spiral downward movement, which movement is supported by the shape of the interior of the basin, which is the subject of another patent application. In any case, the flushing water flow completely wets the inner wall of the toilet bowl 2 as shown and then exits via the siphon elbow as shown, the sewage connection 14 and the pipe section 7 or 7' connected to this sewage connection 14.

As can be readily seen from a comparison of fig. 1 and 2 or fig. 3 and 4 (right), by selecting different duct sections 6, 6', a height adjustment can be achieved. The mechanical fastening can be adjusted as mentioned by means of the elongated hole. In this case, the height adjustment on the sewage conduit side is effected in a manner similar to that of a rinsing water conduit, i.e. by means of different conduit sections 7, 7'. However, the height adjustability of the sewage connection in the normally existing wall can also be utilized.

It can also be seen that the rear portion of the toilet body 1 (located at the rear right in fig. 1 and 2, and at the right side in fig. 3 and 4) is mechanically disconnected from the washing water supply pipe and the sewage pipe. At the same time, the flushing water supply pipe is designed to be flow-suitable, seamless and production-technically advantageous in the main area, i.e. starting from the flushing water connection 5 through the pipe bend 9 up to the flushing water inlet 8, i.e. made in a hollow casting process integrally with the rest of the toilet body 1.

The necessary transitions (at some point) on the flush water connection 5 are unavoidable, but in this embodiment occur directly on the pipe section 6, which pipe section 6 leads directly to the pipe bend, so that a minimum number of transitions and parts are used. The connection between the pipe sections 6, 6 'or 7, 7' and the toilet ceramic body 1, i.e. the connecting

pieces

5 and 14, is effected by means of conventional elastic seals. These connections are reliably and permanently sealed and are more easily accessible in the shown position than, for example, transitions in the vicinity of the flushing water inlet 8, which can also be considered, see also patent document EP3064663a 1. In this embodiment the distance between the flushing water connection 5 and the connection plane, i.e. the plane of the wall, is 12.5 cm.

Fig. 6 shows a view similar to fig. 1, but in the area of the pipe section 6 close to the rinsing water connection 5, a cover 12 of the connection opening 13 arranged on the upper side of the outer surface of the pipe section 6 can be seen, which is uncovered in fig. 8. Fig. 7 shows a section corresponding to fig. 3, in which a flushing water throttle 14 is shown, which is made integrally with the cover 12 and serves to adapt the flushing water flow to various pressure conditions. Reference is again made to patent document EP3064663a 1.

On the connection opening 13, it is also possible to connect, for example, an odour removal device, which is not shown (but a similar form is shown in patent document EP3064663a 1), for which purpose the connection opening can be arranged to the side instead of above. In addition, it is also possible to install cages for cleaning or sterilizing tablets or similar additives, for example.

Finally, comparing fig. 1 and 3, it can be clearly seen that: when at least the pipe section 6, and possibly also the pipe section 7, is first removed and can only be used after the installation of the various components, the upper opening 3 of the toilet body 1 and the available volume thereunder, which can be clearly seen in fig. 1, provide significantly more space for the installation of these different components. In this connection, the invention is also particularly suitable for use in connection with toilets with additional functions, in particular shower devices.

Since the illustrated toilet can also be coupled with a very common straight pipe section 6', for example according to fig. 3, the invention is also directed to a toilet body 1 without said pipe section(s). In the same sense, the not shown seat ring and the not shown cover (or shower device), which are not essential for the invention, can also be removed from the present embodiment and are therefore not an integral part of the subject matter of the invention.
