Description

The invention relates to the installation of a shower toilet.

Water closets (toilets) with a bidet function have been known and used for a long time. Here, a toilet is additionally equipped with at least one shower for cleaning the abdomen of a user, which is often referred to as a short shower. For example, a motorized-moving shower arm of the sub-shower can advance to an operating operation in the toilet bowl and direct a shower water jet upward and go back to function. In many cases, such shower facilities are equipped with other facilities, such as water heaters such as boilers or water heaters, hair dryer facilities, shower arm cleaners etc. For shower facilities are usually an additional shower water connection, for example as cold water connection of a water heater in the shower toilet, and an electric Connection, for example, to supply a water heater, a drive motor or other facilities provided. Basically, technical parts of the shower device can also be arranged "behind" the actual toilet body in a mounting wall; For example, a water heater could be provided there, so that the mentioned additional shower water connection can also affect already heated water. In principle, it is also conceivable within the scope of this invention that only a single further line connection is provided for the shower device, for example such a water connection.

Usually, WCs are connected to a wall behind, in particular if, as preferred here, they have no base and hang freely. For this purpose, in the wall or in a cladded porch in front of the wall usually a toilet connection device is provided as or in a mounting frame for the toilet. Such mounting frames regularly consist of two right and left outside arranged vertical struts of a support frame and held therebetween transverse structures, such as horizontal struts or mounting plates. Usually, load-carrying connection devices for suspending the WC body, connecting pieces for the Rinse water and the waste water of the toilet bowl and connecting devices for the mentioned specific lines of the shower device formed.

The DE 10 2009 030 490 A1 also relates to the installation of a shower toilet and proposes the displacement of the connections in a space behind the mounting wall or a mounting frame provided therein, wherein inclined feed tubes for a telescopic method of a shower arm and a Föhnarms from this room in the toilet Bowl are used in it.

The DE 103 40 295 A1 concerns a template for the sanitary installation of WCs with standardized connection positions.

The WO 2011/083396 A2 refers to a universal mounting frame for mounting wall-mounted WCs or bidets.

The EP 0 558 127 A1 also describes a mounting frame, which is designed in a variant for a wall-mounted toilet and in another for a wall-mounted bidet.

The EP 1 803 859 A2 describes the production of a wall element for fixing wall-hung toilets, bidets, urinals or washbasins.

The DE 199 53 682 A1 is aimed at a universal mounting frame for mounting a toilet, a bidet or a washbasin.

The GB 2 466 763 A deals with a combined toilet / bidet unit.

The DE 196 24 522 A1 refers to the upgrade of a conventional toilet bowl with a conventional bidet fitting.

In the context of third-party objections, a document was filed with the title "Planning information closomat info", which bears the date of June 1994 and whose authenticity and affiliation with the previously published state of the art has confirmed the examining division.

The object of the invention is to provide a practical and inexpensive solution for the installation of a shower toilet, especially with regard to the shower water pipe.

To this end, the invention firstly relates to a new use of a toilet connection device for the wall-side connection of a shower toilet, in which the shower toilet is connected to the toilet connection device and the toilet connection device is equipped with a connection device side Spülwasserzuleitungs connection device for a toilet A shower toilet, a connector-side sewer connection means for the toilet bowl of the shower toilet and a connector-side shower water pipe connection device in the form of a separable shower water line interface or a positioning device for fixing the shower water pipe position of a shower water pipe to the shower device, to a before the Level of the wall or the WC connection device lying separable shower water line interface leads, wherein the Spülwasserzuleitung and the sewer line are connected to the shower toilet, with a Mittelpu nt of the sewer at the sewer port and a center of the purge water supply to the purge water supply port define a vertical reference line, and the circle center of a section of the shower water conduit at the shower water conduit port or at the locator of the reference line is greater than 15mm and less than 75 mm horizontally, characterized in that the separable shower water line interface between two sections of the shower water pipe is connected to the shower device of the shower toilet in the plane of the wall or bowl side in front of the plane of the wall or the WC connection device.

Second, the invention relates to a new use of a shower toilet for a wall connection to a wall-side toilet connection device, wherein the shower toilet is connected to the toilet connection device and is equipped with a WC-side Spülwasserzuleitungs connection means for wall connection, a WC-side waste water connection device for wall connection and a WC-side shower water pipe connection device in the form of a separable shower water line interface or a positioning device for fixing the shower water pipe position of a shower water pipe to the shower device, to a before the Level of the wall or the WC connection device lying separable shower water line interface leads, wherein the Spülwasserzuleitung and the sewer pipe are connected to the shower toilet, wherein a center of the sewer pipe at the sewer connection means and a center Spülwasserzuleitung at the Spülwasserzuleitungs connection means define a vertical reference line and the circle center of a section of the shower water pipe to the shower water pipe connection device or to the positioning of the Bez Stroke more than 15 mm and less than 75 mm horizontally spaced, characterized in that the separable shower water line interface between two sections of the shower water pipe to the shower device of the shower toilet in the plane of the wall or bowl side in front of the plane of the wall or the WC connection device is connected.

Preferred embodiments are the subject of the dependent claims.

According to the invention, at least one further connection device or positioning device for the shower water line of the shower device lies with respect to the width within the middle 150 mm, but outside the middle 30 mm. In other words, the distance from the center is smaller than 75 mm and larger than 15 mm. In this case, the center should be defined by the center of the Spülwasserzuleitung on the wall side and toilet-side connection device of Spülwasserzuleitung and the middle of the sewer line to the wall side and toilet-side connection device of the sewer. These two lines are basically centered and one above the other and therefore form an independent of details of the installation of the shower toilet reference point.

The shower water pipe connection device or positioning device according to the invention relates to the shower water pipe, ie the water supply for the Shower facilities. A centrally in the above sense, and in particular an inventive arrangement is particularly preferred in two shower lines, in particular in addition to an electrical line.

In principle, further internal positions are increasingly preferred, at least up to a certain upper limit. Accordingly, instead of the mentioned 150 mm, the following central widths are increasingly preferred as upper limits (in mm in each case): 125, 120, 115, 110. More preferred lower limits are in the following order: 40 mm, 50 mm, 60 mm, 70 mm, 80 mm ,

Of course, these symmetrical statements on both sides do not mean that two positions must be present or two connection positions must be symmetrical. It is thus quantified only as an invention to understand area. For example, the narrowest limit of 110 mm means that the circle center of the shower duct should be at most 55 mm horizontally away from the vertical center line.

In this context, it is also significant that in the vast majority of today's WCs quasi-standardized connection positions for the Spülwasserzuleitung, the sewer line and mechanical and hanging WCs load-bearing fasteners, especially threaded rods exist. In this case, the said line connections are provided centrally, of course, the Spülwasserzuleitung runs over the sewer line, and are in a height range just below the Spülwasserzuleitungs connection device laterally 90 mm and 115 mm from the center remote mechanical connection devices specified, in particular threaded rods on the wall side and corresponding mounting holes on toilet side.

Thus, positions for the shower water pipe connection device or positioning device according to the invention are basically "closer to the center" than in the prior art, but more preferably even closer to the center than the outer and most preferably even closer to the center than the inner usual position the mechanical attachment.

This arrangement closer to the center facilitates the accessibility of the connection devices for a fitter or maintenance technician, in particular from below, and permits or uses a corresponding configuration of the rear side of the WC. Normally, WCs have an area which is kept clear of the rear side around central rinsing water supply lines and sewers of the toilet bowl. in other words, the contact surfaces of the toilet body are on the mounting wall outside of this free area. A corresponding arrangement of the mentioned connection devices thus allows a design of the WC, in which one can reach the connection devices from below, without having to disassemble the toilet body. This applies depending on the application for an achievement by hand or at least with a tool. For the sake of illustration, reference is made to the exemplary embodiment. There, the reserved area is approximately inverted V-shaped, and the terminal means on the sewage pipe can be accessed from below. (According to this example, a toilet can therefore be connected to a device according to the invention per se or with adapted rear configuration.) There, these connection devices are furthermore located just outside the area of the flushing water supply line for the toilet bowl and with respect to the vertical extent with respect to the horizontal extension approximately at the level of the lower edge and also at the height of the load of the toilet body supporting connection devices. However, these are only preferred and by no means compelling positions.

Furthermore, assembly or connection or maintenance work in the area between the flushing water supply line and the sewage line are regularly impeded by these lines or their connection devices. It is therefore provided that the circle center of the section of at least the shower water pipe to the shower water pipe connection device or positioning outside the actual center, specifically the middle 30 mm, is located.

By the term "connection device" is meant a separable interface, that is, for example, an electrical plug-in contact or a watertight coupling between two shower line sections. However, the term "positioning" refers to a wall-side or toilet-side device, the only the wall-side position of a corresponding shower line or the toilet sets. For example, could be mounted in a extending between the vertical frame struts of a mounting frame horizontal mounting plate a hole through which an extra-long shower line is guided and forward, so in the direction of toilet bowl, can be continued. In this case, the actually separable interfaces could also be slightly in front of the plane of the wall or the mounting frame; but they are preferably approximately in this plane. The analogous applies to an excess length of shower pipe at the back of the WC and an arrangement of an interface behind the front of the wall.

Generally, with respect to the vertical arrangement, a position of the attachment means is on the one hand below the top edge and preferably the center line of the flush water supply to the toilet bowl at the flush water supply port and on the other hand above the bottom edge and preferably above the center line of the waste water line for the toilet bowl at the sewer connection for reasons of accessibility and simplicity of construction. With regard to vertical positioning, according to the invention arrangements are provided in the area around the load-carrying connection devices which are between 15% above their vertical height and 40% below, the percentage values relating to the vertical height of the load-bearing connection devices relative to the ground. Further preferred are upper limits of plus 10% and plus 5% and, independently, lower limits of minus 30%, minus 20% and minus 10%. For adjustable mounting racks, a ground position in the middle of the adjustment range is meant. The statements relate again to at least one shower line.

In the prior art, however, the connection means for the specific shower lines of shower toilets were positioned very far outside, which concerns the horizontal direction. They were either in a two vertical frame struts connecting mounting plate directly within the frame struts or even outside the frame struts and thus in the sense of claim 1 at about 390 mm or above (195 mm distance to the center). This probably has the reason that in many shower toilets, the shower lines are not hidden at all behind the toilet body, but are visibly connected next to it. In particular, this applies to shower toilets with a shower attachment, ie one on an ordinary toilet body Between the toilet seat and the mounting wall mounted technology housing that contains the necessary technology for the shower equipment outside and above the rest of the toilet body. Such retrofittable solutions are then connected via laterally from the toilet body and visibly guided lines. In this sense, it will have sought to keep the corresponding toilet connection devices or mounting racks for essay solutions and integrated shower toilets, in which at least part of the shower device is integrated in the toilet body, universal.

In the central arrangement according to the invention is a Sichtverdeckung, especially through the toilet body, preferred and easily possible.

The invention relates, as already stated, the use of toilet connection devices which are designed for a position according to the invention at least one shower water pipe to the shower water pipe connection device or positioning device and also for a further outward position. This can be taken into account for different toilets that may only partially suitable for a position according to the invention. For example, a guided in a mounting rack line or run in the mounting frame pipe channel could be designed to be sufficiently flexible, so that they can be converted, for example, between a further inside and a further outward position in the mounting frame. In a favorable solution, such a pipe channel is branched and thus offers two different pipe channel pieces to choose from, each of which fits to its own position. Of course, more than two alternatives are conceivable. For example, such a pipe channel can be guided by a arranged over a cistern integrated in a cistern valve for a shower water pipe approximately along one of the frame struts down and slightly above the terminal positions or position of the positioning then to this approximately V-shaped branching configured.

The invention is explained in more detail below with reference to an exemplary embodiment:

FIG. 1

shows a partly sectional and partly perspective toilet body of a shower toilet according to the prior art;

FIG. 2

shows a rear view of a corresponding but according to the invention Klosettkörpers;

FIG. 3

shows a toilet connection device according to the invention for the wall-side connection of the shower toilet from the Figures 1 and 2 in front view.

In FIG. 1 can be seen in a toilet toilet body shown in perspective, and seen from obliquely behind and slightly elevated. FIG. 1 is also cut, so shows only one half of the toilet seat. Clearly, a classic toilet bowl 1, a knee 2 of a drain siphon and, subsequently, one to the right pointing pipe socket 3 as sewer connection device of the toilet to the wall connection. Furthermore, it can be seen above the pipe socket 3, a further pipe socket 4, namely a Spülwasserzuleitungs connection device. This leads into a flushing channel 5 surrounding the upper edge of the toilet bowl 1. Above the flushing channel, the toilet bowl body is essentially horizontal and is closed flat upwards.

On this flat top of the toilet seat, a known shower attachment can be constructed, from which, for example, a shower arm can be moved into the upper opening of the toilet bowl 1 obliquely downwards and forwards. Conventionally, such shower heads are even with regard to their power and shower water connection lines with lateral connection devices or laterally outgoing connection lines provided. With the side here is the area approximately above the in FIG. 1 upper rear edge of the lavatory body in its straight portion, namely meant to the right of the bowl opening.

Incidentally, shows FIG. 1 on the right an approximately triangular profile rear wall portion 6 for engagement with a mounting wall. This profile rear wall portion 6 is closed between the illustrated approximately vertical (V-shaped) frame struts and the horizontal struts. It contains a recognizable cylindrical hole 7 as a mounting hole for a bolt for mechanical attachment of Klosettkörpers, so as a load-bearing connection device. This mechanical assembly is conventional and common.

FIG. 2 shows largely the same toilet body, with the same reference numerals are used accordingly. Here is the line of sight exactly from the back horizontally on the back, with the second half of the toilet bowl body is shown.

One recognizes clearly that the already in FIG. 1 shown profile rear wall portion 6 together with its mirror-symmetrical counterpart leaves a middle surface free, which is filled up through the pipe socket 4 of Spülwasserzuleitung and below, but with space right and left thereof, the pipe socket 3 includes the sewer. This free area is roughly like an inverted "V" with Rounding or shaped like an inverted "U" with slightly divergent legs. It can be clearly seen that at the outer edge of this free area two pipe sections 8 and 9, one on each side, are located. These are a shower water supply line 8 and a power supply line 9 or conduits for it. These are at the same level in terms of vertical height as already shown FIG. 1 With regard to the horizontal extent they are offset 50 mm from the center to the outside, so at a distance from each other of 100 mm. This refers to the respective circle center of the section through the line, as indicated in the drawing. In contrast, the centers of the bolt mounting holes 7 90mm outside the center, so in a mutual distance of 180 mm.

It can easily be seen that the corresponding lines 8 or 9 can continue from there, for example, obliquely upwards and outwards and run up inside inner cavities of the ceramic toilet body behind the profile rear wall 6 and, for example, by an in FIG. 1 not provided through opening in the top of the toilet seat can be passed through in a shower attachment. The cables can be used in FIG. 2 shown position due to their own dimensional stability and / or hold as a result of a fixation, for example, the ceramic toilet body. For example, they can be glued by an adhesive body. In principle, flexible lines with an undefined position are conceivable, which are brought into the illustrated positions during assembly and are designed to that extent.

A fitter or service technician can reach the positions according to the invention of the shower lines 8 and 9 without any particular difficulties by hand or with a tool from below, even in the assembled state of the shower toilet. For this purpose, he can pass by the sewer pipe socket 3 and does not have to grab in the slightly more difficult area between this and the pipe socket 4 of Spülwasserzuleitung "around the corner". It can also be seen that the positions of the lines 8 and 9 are variable depending on the detailed design of the rear contact surface of the toilet seat body to different sides or can be. In particular, could also be the area: within the profile rear walls 6 partially accessible and thus could also positions horizontally outside the mounting holes 7 for the load-bearing bolts into consideration.

For example, parts of the profiles of the profile rear walls 6 or the fillings could be omitted therein and thus more surfaces for load-bearing connections or shower line positions according to the invention can be developed. In principle, it is preferred within the scope of this invention to arrange the shower line positions according to the invention in accordance with the explained geometric features (with respect to their vertical and horizontal position) within profile frames of rear profile rear walls of a shower toilet, and most preferably within a central exposed area between such profile frames this example shows.

The illustrated pipe sections 8 and 9 are essentially symbolic. Preferably, they terminate in an interface, for example, with a connector or other connector means located in or slightly in front of or behind the illustrated area. As already explained, however, the "interfaces" could also lie within the toilet bowl body or in the installation wall, and nevertheless the drawn or comparable positions of the lines can be selected.

FIG. 3 shows a corresponding toilet connection device. This has, in a conventional manner, a mounting frame with two vertical steel profile struts 10 on adjustable feet and a lower steel profile cross-member 11 and another upper (not exactly drawn) steel profile cross-beam. The cross-beam 11 carries an angle pipe section 12, namely the wall-side connection device for the sewer line of the toilet. In addition, a cross plate 13 as a mounting plate with optional inner and outer mounting holes 14 and 15 for the aforementioned fastening bolts, so matching the Aufnahmelöchem 7 in Figures 1 and 2 , intended. The inner mounting holes 15 are in the in FIG. 1 and FIG. 2 assumed mutual distance of 180 mm, the outer, which could also be used, but require an adaptation of the Klosettkörpers, at a mutual distance of 230 mm. Furthermore, the mounting plate 13 centrally contains a recess with a semicircular shape above and rectangular shape below, through which a wall-side Connection device 16 for the Spülwasserzuleitung, so complementary to the pipe socket 4 in the Figures 1 and 2 protrudes. Above the mounting plate 13 with these devices is a cistern 17, so a water tank for the Spülwasserzuleitung and above this a trigger mechanism 18 for the flushing process.

So far described the elements are in FIG. 3 conventional and would be used in conjunction with a toilet seat according to FIG. 1 form a conventional toilet arrangement. According to the in FIG. 2 Supplemented lines 8 and 9 are in FIG. 3 in the mounting plate 13, an opening 19 for a power connection, so matching the line 9 in FIG. 2 , And another opening 20 with a shower water connection, so matching the line 8 in FIG. 2 , From the opening 20 from a first dashed line (because arranged behind the mounting plate 13) plastic molded body is shown as a duct and numbered 21. This ultimately leads into the area behind the release plate of the above in FIG. 3 there is a fresh water valve, which supplies the cistern 17 and from which the shower water pipe is branched off. This line runs within this empty channel 21 to the opening 20th

In this case, the empty channel branches behind the upper edge of the mounting plate 13 in the manner shown and leads with a further possible line route to a further opening 22 in the mounting plate 13, which apart from its further outward position of the opening 20 corresponds.

This position of the opening 22 is conventional in itself; Such positions are connected to shower toilets on the market. In the present case, the toilet connection device in FIG. 3 be flexible and allow a threading through the water pipe for both terminal positions 20 and 22. Thus, shower toilets with inventive connection positions as in FIG. 2 or conventional shower toilets are connected. The latter can be both those with concealed connection, that is to say with a view covering given from the front through the shower attachment or the rest of the toilet bowl body or even those in which the connection is visible. The connection device after FIG. 3 allows it together with a shower toilet according to FIG. 2 an inventive use and the preparation of a toilet arrangement according to the invention, but also another.

It is easy to see that the mounting positions 19 and 20 within the mounting plate 13 could also be slightly higher or farther out. They could also be arranged below the mounting plate 13, for example, mounted on the lower edge or independently. Also, the mounting plate 13 may be extended downwards.

The interfaces, ie the connection devices themselves, with which the lines from the toilet body in the installation wall in FIG. 3 are inherently conventional and will not be explained further.
