Description

The invention relates to a built-in wall mounting cistern for a toilet ceramic comprising a water connection, an actuator, a connecting pipe between the installation cistern and the toilet ceramics and a moisture and leakage protection.

The installation cistern is used for flushing a sanitary ware, preferably a toilet ceramics. The installation cistern is connected to water supply lines via the water connection. A valve for the water connection ensures that the installation cistern keeps a constant amount of water. Now, if the actuator is operated to rinse, an opening in the installation cistern to the connecting pipe is released by another valve. Through this opening, the water flows from the installation cistern for flushing in the toilet ceramics. Then the installation cistern refills with water from the water connection.

Moisture and leakage protection is provided to prevent water damage, which may be due to condensation or leaking water from a leak or similar. could arise on the installation cistern and the connected components. For this purpose, it can be provided, for example, that unintentionally leaked water is absorbed and discharged by the moisture and leakage protection.

In addition, a mounting frame and a cover plate can also be provided. The built-in rack serves to accommodate the installation cistern and the connected components in a wall or pretext. Further, a cover plate can be attached to the cover to cover the rack.

Areas of application of the invention are wet rooms, in particular sanitary areas in buildings, which were built of wood, for example wooden houses. Unlike concrete or stone living rooms, wood houses are at an increased risk of irreparable damage to the building fabric of a wooden house due to the vulnerability of wood to mildew and rot.

In the Scandinavian countries, houses are mostly made of wood. In this region, especially in Norway, there are therefore official regulations and recommendations for avoiding water damage and its possible consequences, for example the technical regulations of the Planning and Construction Act 1997 (TEK).

Particularly relevant are TEK § 9-1 "Installation" and TEK § 9-5 "Sanitary Installations". From them also the now described "pipe in pipe" system emerges, after which all water pipes "pipe in pipe" are to be laid. In this case, an outer tube serves as a protective tube for an inner PEX tube, in which the water is guided. It is a plastic tube made of cross-linked polyethylene. If the inner tube breaks, the water enters the protective tube. This leads it into an open, accessible floor drain. The protective tube prevents leakage of water into the building substance and thus water damage. At the same time the pipe break or water damage can be detected. Countermeasures, such as closing a main or Distribution line, can be initiated. For this purpose, it is also customary to provide sensors and protective valves. In the publication " Ror-i-ror-systemer ", published by the Construction Research Institute Norway in 2006 (ISBN 82-536-0925-6 ), there is a detailed description of the "pipe in pipe system".

Furthermore, these provisions also apply to avoid water damage by a built-in cistern application. The Norwegian licensing authority SINTF published the following recommendations.

To install installation cisterns, SINTF recommends laying a sealing membrane in the wet area of a sanitary area, for example a bathroom, first of all sealing it, then tiling it. Only then is an additional, separate pretext to install the installation cistern to build. The space in the pretext for installing the cistern is easily accessible, for example, by a removable cover plate. The dimensioning of this space should also make it easy to maintain and replace the cistern and pipes.

Furthermore, it is recommended to provide a bottom slot-like opening in the pretext, through which any water, caused by a fault, can pass from the wall into the bathroom. Similar to the described "tube in tube" system thereby fulfilling two functions to avoid water damage. On the one hand, the damage can be detected early, on the other hand, the water can run off without damaging the building fabric. For this purpose, bathrooms are equipped according to the Norwegian standard with a floor drain. To support the process, SINTF recommends providing a slope in the pretext.

Such systems are sold, for example, by Geberit. In the lower region of the recess of a pretext a bevelled attachment is formed. The slope of the essay leads to a tube, which in a verfliesten cover plate made of plasterboard, wood or similar. is trained. Thus, it is possible that any leaking water from the room in the pretext can drain through the tube in front of the cover plate. This water then flows through a floor drain in the bathroom.

Furthermore, systems for simultaneous installation during the Rohinstallation a bathroom are still known. These have a built-in frame, which serves to accommodate the installation cistern, which is sealed to the front. On the front of connecting pipes between the toilet ceramic and the cistern or the sewer system are provided. The front is with a cover plate made of plasterboard, wood or similar. coverable.

Such a system is available from Bryne Plast. The built-in frame is designed as a front and top open, dense plastic box. On the underside of the plastic box a tub is formed. In the lateral, lower front area of this tub, a tube is formed, which dissipates any leaking water.

A similar system is offered by VINAR VVS. A built-in wooden frame is lined to the front and top with a flexible, waterproof membrane. By folding the membrane, a trough is formed on the underside of the mounting frame. In a known manner, a tube for the passage of any water occurring, provided on the tub.

The installation effort on site of the systems described is relatively high. In the former system that is So first to completely tiling the bathroom, then there is a separate pretext to build, which must be tiled again. Disadvantages are thus the increased material costs, the high expenditure of time and the associated increased installation costs. The on-site assembly of the latter two systems is a multi-stage and therefore expensive process.

It has been found that water damage in the cistern itself occurs more frequently than a leaking cistern. Splash then usually passes out of the inspection opening of the cistern against the cover plate. In the systems mentioned, it is therefore usually necessary after a water damage to replace the cover plate, which is formed predominantly of wood or plasterboard. This in turn generates follow-up costs.

Furthermore, the current described water courses represent an unsightly interruption of the wall or the pretext, in particular the asymmetrically arranged sequences of the latter two systems.

Functionally, these processes are also not satisfactory. Through the open drain vermin and pests can get behind the cover plate and settle there. It should also be remembered that moisture that accumulates in the space behind the cover plate due to either water damage or normal use of the bathroom may cause odor due to lack of adequate venting.

Currently, the systems described do not have a large market share in Scandinavia, including Norway. Reasons are possibly the disadvantages described, in particular the increased effort in terms of installation and costs.

It is also possible that the systems are the possible buyers not completely convincing in terms of reliability of protection against water damage. Since the risk associated with water damage can be a threat to existence, the requirements for the acceptance of the potential buyer are particularly high. A system against water damage should therefore be as robust and safe as possible.

Based on the above-mentioned prior art and the associated disadvantages, the invention is intended to provide a built-in cistern with moisture and leakage protection for installation in a wall, which is particularly easy to install quickly and on site, while being robust, safe and aesthetic and unattractive is designed in terms of pests or odor.

In the solution according to the invention, this object is already achieved in that the moisture and leakage protection as a mounting cistern and connecting tube surrounding, flexible and waterproof protective cover is formed and that the underside of the protective sleeve a hose-like extension is formed with at least one lower-side opening at the end , Accordingly, the protective cover surrounds all components of the installation cistern in the installation position and seals it against leakage, but at the same time is designed so that actuation of the cistern is possible. The particular advantage of this solution is that it can be retrofitted to existing cisterns without conversion and greater effort.

Ideally, the solution according to the invention corresponds to the recommendations of the SINTF and the regulations according to TEK.

The solution according to the invention preferably comprises a built-in cistern designed for installation in a recess of a wall. The installation cistern is preferably arranged in a built-in rack. This is preferably as Rectangular frame made of profiles of metal, in particular hollow profiles of aluminum or steel, formed. Other materials are possible, such as plastic or wood.

The mounting frame comprises receiving means for receiving the components of the solution according to the invention and for mounting in the recess of the wall. As receiving means may be provided, eyelets, thread and recesses for receiving components u.ä. For adjustment in the recess, it may be useful to make the mounting frame height adjustable, for example by a telescopic mechanism.

To cover the recess, a cover plate made of plasterboard is preferably provided, which is preferably clad with tiles. It is also possible the plate made of glass, plastic, stainless metal or similar. train. With regard to the determination of the SINTF, it is particularly useful to attach the cover plate removable and sealing over the recess of the wall. For this purpose, corresponding seals and fastening means may be formed on the mounting frame and / or the cover plate. Such fasteners may be, for example, screw, snap, clamp, or spring connections. The seals can, for example, as rubber profiles, foam edges or similar. be educated. The cover plate is preferably mounted in such a way that it is flush with the wall covering of the bathroom. It may also be provided to plaster the cover plate with the surrounding wall and then tiling.
The installation cistern contains all the necessary connections and mechanisms for flushing a lower-side trained sanitary ware. The water connection can be designed in particular for a PEX inner tube. To avoid the aforementioned water damage in the cistern special safety devices can be formed on the water connection be. These may include, for example: safety valves, eg ball shut-off valves, seals eg compression fittings, as well as safety hoses, eg reinforced hoses with carbon fibers, nylon or stainless steel braiding, etc.

The sanitary ware is preferably designed as a toilet ceramics. However, it is also possible a bidet ceramic or other related sanitary devices. Thus, it is possible to use the solution according to the invention of the moisture and leakage protection, for example, for a concealed water heater.

It is intended to connect the cistern via a connecting pipe with the cistern, which preferably consists of plastic. The cistern has an actuating device, which is preferably mechanically switchable. The actuating device preferably comprises a button. It is also possible to form the actuator contactless. For example, the flushing may be electronically switchable by remote control. In the standard case, however, the solution according to the invention comprises a commercial cistern with a mechanical actuator. A passage opening for a button of such an actuating device is preferably formed on the cover plate.

Essential to the invention is a moisture and leakage protection. This is preferably designed as a, the built-in cistern and the connecting tube surrounding, flexible, waterproof protective cover. Such a protective cover is preferably formed as a polyethylene film with Polypropylenbeflockung. Also possible are materials or material combination with similar properties.

The protective cover is preferably tight and follows the shape of the cistern and the connecting pipe. Accordingly, it is possible that the protective cover has a hose-like extension which is provided for the connecting tube. The protective cover has at least one opening, which is preferably formed at the end of the described extension and the connecting tube is arranged within this opening. The opening itself is preferably arranged in front of the cover plate behind the toilet ceramic. Such an opening then serves to drain any water behind the toilet ceramic. From there, the water can drain into a floor drain of the bathroom. Water damage is thus detected early and can be remedied. Advantageously, such a drain opening is formed invisible to the user.

It is possible to provide at the said opening edges, which can be sealingly connected to the cover plate. The edges can be plastered, for example, with a tile covering on the cover plate. It is also possible to provide a detachable, sealed connection, for example by rubber sealing rings, metal clamps or the like.

If no floor drain in the bathroom should be provided, it is also possible to direct the water drain directly into the toilet ceramic. Preferably, it is possible to sealingly close the lower-side opening of the protective sleeve with a collar around the connecting tube. Possibly occurring water could then collect in this area. Furthermore, a closable by a valve opening in the connecting pipe may be provided, through which the collected water enters the connecting pipe and ultimately to drain into the toilet ceramic. This valve may be mechanically formed so that it only opens when outside the connection tube in the protective cover Water has accumulated.

The valve can also be designed as an electrically switched valve. For this purpose, preferably a sensor is provided in the area between the protective cover and the connecting pipe. This opens the valve as soon as water is detected in the protective cover. Since no puddle or the like alerts the user to the water damage, it may also be particularly convenient that the sensor is connected to a warning device. As a warning device, for example, a beep, a warning light o.ä. be educated. Such a warning system can also be useful in the previously described variant with floor drain.

The solution according to the invention is preferably pre-installed. This applies to all possible combinations of the aforementioned elements of the invention. Particularly preferably, the cistern and the connecting pipe are already equipped with the protective cover before installation on site. For this purpose, the shell preferably has a further upper opening, which makes it possible to put the protective cover over the installation cistern and the connecting tube, as it were, over a loose stocking. It is also possible to close the said top opening. For this example, elastics may be provided in the edges of the opening. It is also possible to optionally provide a hood-like cover in the region of the opening. The cover could be slipped over or under said opening. To fix the cover, elastics may be provided in edges. Also possible are Velcro u. Snap fasteners and fastening rivets and the like. The training may also be such as to close the opening by means of the cover tight. It is possible, this closure permanently, for example by adhesive, welding or even solvable form, for example by a snap closure with flexible plastic profiles.

The steps of the preferred assembly method will now be described. After the installation cistern and the connecting tube are provided with the protective cover, both are inserted into the above-described frame-shaped mounting frame. For this purpose, preferably previously described receiving means are formed on the mounting frame. These preferably correspond with fastening means, which are provided on the protective cover and can be formed, for example, as fastening eyelets. The mounting frame preferably comprises at least one transverse strut, which preferably has an opening for receiving the connecting pipe. The connecting tube may protrude through the opening, together with the tubular part of the protective cover, beyond the plane defined by the frame-shaped mounting frame. The outstanding part of the connecting pipe thus serves to connect to the WC ceramic. For this purpose, an additional connection connecting pipe can also be provided.

Similarly, the cross member for receiving the connecting pipe, a cross member for a sewer pipe of the toilet ceramic may be formed. By the described fastening means, the mounting frame can be secured in a corresponding recess of a wall.

Before connecting to the WC ceramic, a recess with the built-in frame must be provided with a cover plate. This cover plate preferably has corresponding passage openings for the connecting pipes. The attachment of the cover plate can then be done in the manner described above. Thus, the installation of the installation cistern is completed after a possible tiling of the cover plate.

a side sectional view of the embodiment according to FIG. 1 after installation.

FIG. 1 shows a built-in cistern 1 made of plastic and the components essential for installation. These include a mechanical actuator 13, a mounting cistern in mounting position frame-mounted enclosing frame 2 steel profiles and telescopic mechanism 8 for height adjustment, a connecting pipe 3 made of plastic, a protective cover 4 made of polyethylene film with Polypropylenbeflockung and a cover plate 5 made of plasterboard.

Furthermore, the following safety devices are arranged on the non-illustrated water connection for a PEX inner tube: a Kugelabsperrhahn, a compression fitting and a short armored hose.

The protective cover 4 according to the invention surrounds the flushing cistern 1 completely and continuously with the connected connecting pipe 3. Laterally on the protective cover fastening means, not shown, are formed as fastening eyelets. Furthermore, the protective cover 4 has two nozzle-like openings 6, 7. By means of screws, not shown, the protective cover 4 and thus also the installation cistern 1 and the connecting pipe 3 are fixed to the corresponding receiving means of the mounting frame 2. The receiving means of the mounting frame 2 are in the present case designed as a thread.

The connecting pipe 3 is formed bent and comprises a vertical and a horizontal part. The horizontal part of the connecting tube is arranged in a passage opening of a transverse strut of the built-in frame 3, not shown.

The fastening means for attachment in a corresponding recess of a wall, not shown are formed as eyelets on the top and bottom of the mounting frame 2.

A cover plate 5 is releasably fixed by screws to the mounting frame 2 and has various through holes. Through this, among other things, a tubular extension of the protective cover 4 together with the top opening 7 and the protruding edges of the protective cover 4 in the region of an opening for a button 6 for a mechanical actuator 13 in front of the cover 5.

FIG. 2 shows the installation cistern 1 after installation in the installed position. A toilet ceramic 10 is connected by means of the connection connecting pipe 12 via connecting pipe 3 with the installation cistern 1. Furthermore, a drain pipe 11 is connected to a drain of the toilet ceramic 10. Through a corresponding passage opening in the cover plate 5, the drain pipe 11 is connected to a waste water connection, not shown, behind the cover plate 5. The lower-side opening 6 is striped over the terminal connection pipe 12 to behind the WC ceramic. The edges of the protective cover 4 in the region of the opening for a button 7 are plastered under a tile covering 9 Abdeckeckplatte 5. The cover plate 5 itself is plastered flush with the tile covering 9 of a wall, not shown.

Now, if water unintentionally from the installation cistern 1 or the connecting pipes 3, 12, this water is collected by the waterproof protective cover 4. The protective cover 4 thus prevents leakage of the water in the building substance behind the cover plate 5. The collected water is then passed through the protective cover 4 along the connecting tubes 3, 12 to the lower-side opening 6 of the protective cover 4. From this opening 6, which is arranged behind the toilet ceramic, the water flows off. The outflow of this water from the opening 6 is in the FIG. 2 represented by drops. Now water can continue to drain into a floor drain, not shown. In this way a water damage is avoided.
