Description

The invention relates to a rinsing station for a ring or series line system. Furthermore, the invention relates to a series line system and a loop system, each with such a rinsing station.

Nowadays, it is common to install row or loop systems when installing water pipes. Typically, hot water and / or cold water pipes in a room of a building or on a floor of a building are routed in series from consumer to consumer in a series pipe system. In this case, one last consumer of the consumers connected in series should be a frequently used consumer, for example a bathroom sink. This ensures that when using this last consumer water is flushed through all the upstream pipe sections of the cold water and / or hot water pipes of the room or the floor (floor). This stagnation areas can be avoided in pipe sections in which existing water is not or rarely moved or rinsed, such as in a little-used bathtub. Such areas of stagnation would often cause hygienic deficiencies, especially due to bacteria formation (eg Legionella).

In the case of loop systems, in addition to the piping systems, cold water or hot water pipes from the last consumer at the beginning of the pipeline will be used Row line laid. As a result, a line ring for the cold water or hot water pipes is formed. This has the advantage that with each use of whichever consumer water flow from both directions to the consumer and thus regardless of the operation of a connected to the loop consumer always all the pipe sections are flowed through.

In the above-described piping systems flushing stations can be used in addition, which further improve the hygiene of such systems. Typically, a rinse station is installed in a series or loop system and flushes it automatically. This is particularly advantageous if the Reihenbeziehungsweise loop system is not operated for a long time, for example, if an apartment, a house or a building section are left empty for a long time.

An object of the invention is to provide a concept for a flushing station which contributes to efficient assembly.

A rinsing station for rinsing a ring or series conduit system is disclosed. The series or loop system is set up, for example, for a drinking water installation. The rinsing station has a cold water connection for connecting a cold water line and a hot water connection for connecting a hot water line. Furthermore, the rinsing station has a wastewater connection, wherein the cold water connection and the hot water connection are fluidically coupled to the wastewater connection. The rinsing station is characterized in that the cold water connection, the Hot water connection and the waste water connection are assigned to a bottom of the rinsing station.

Because all connections of the flushing station are assigned to a common side of the flushing station, the flushing station can be coupled fluidically via only the common side with pipelines. In other words, pipelines such as cold water, hot water and drainage or sewage pipes are connected or fluidically coupled exclusively via the common side to the rinsing station. In other words, said ports are fluidically connectable from a common side. For example, a piping of the rinsing station takes place only on the common side of this.

The common side is preferably the underside of the rinsing station, where "bottom" means that this side is assigned to a floor, in particular facing it.

The described rinsing station contributes to the efficient mounting of pipelines. In particular, all the pipelines that lead to the rinsing station or lead away from it can be routed bundled over one side. In particular, it is not necessary to lay individual tubes around the rinsing station in order to establish a fluidic connection on another side of the rinsing station, for example on an upper side. Furthermore, it contributes to the fact that fewer pipes are required, in particular lengths of the pipes can be reduced. This saves manufacturing and assembly costs.

Typically, cold and hot water pipes in a floor of a floor of a building or at least moved close to the ground and from bottom to top (against the direction of gravity) to built consumers such as sink or the like out. The fact that all connections are assigned to the underside of the rinsing station, the pipes can thus be performed on the shortest path perpendicular to the ground to the rinsing station. Another advantage is that particularly in masonry or solid walls particularly few recesses for the laying of the pipes to the rinsing station must be provided or introduced. In particular, only one or more suitable recesses for the lines are necessary on the common side of the rinsing station. The lines can thus be efficiently connected to the rinsing station. As a result, considerable time and therefore assembly costs can be saved, especially on a construction site.

According to one embodiment, the cold water connection, the hot water connection and the waste water connection are opened substantially to a common plane. The common plane faces the common side of the flushing station. The common plane is, for example, in a mounted state, a floor of a room of the building. The common plane may, for example, also be an imaginary plane which faces all the openings of the described connections of the rinsing station. It is not absolutely necessary that cross sections of the openings are arranged parallel to the common plane. Rather, it is also possible that the cross-sections of the openings of the terminals are arranged at a certain angle to the common plane. In other words, all cross sections of the openings of the terminals or the Connection pipe at a maximum angle less than 90 ° to the common plane aligned. This contributes to efficient assembly.

According to a further embodiment, the cold water connection, the hot water connection and the waste water connection point substantially in the same direction. The direction is vectorial. In other words, the ports and the sewer port point in a direction away from the common side of the purge station. This contributes to efficient assembly.

According to a further embodiment, longitudinal axes of the cold water connection, the hot water connection and the waste water connection are aligned substantially parallel to one another. At least in the region of the openings of the terminals, the longitudinal axes are substantially parallel to one another. Substantially parallel means that the longitudinal axes not only run exactly parallel, but can also be aligned with each other with a slight angular deviation from one another, for example of a few degrees. This makes it possible to lay the pipeline for connection to the cold water connection, hot water connection and the waste water connection parallel to each other and thus extremely space-saving. This allows a compact and space-saving installation of pipelines. This contributes to the fact that only small recesses in walls or masonry must be provided.

According to a further embodiment, the longitudinal axes extend in a common plane. As a result, the lines are routed and connected in a common plane to the rinsing station.

According to a further embodiment, the cold water connection and / or the hot water connection to a profiled support sleeve, a compression sleeve and / or a plastic ring. This allows pipes to be quickly and easily connected to the appropriate connections. Typically, an end of a pipeline is pushed between a compression sleeve and a support sleeve and then pressed firmly and tightly radially by means of a pressing tool. The plastic ring is used, for example, to secure the compression sleeve to the support sleeve and can also have a Verpresskennzeichnung which is separated during the pressing process by means of the pressing tool.

Alternatively or additionally, the connections may also include an inner or an outer thread for the connection of pipelines.

According to a further embodiment, the rinsing station has a further cold water connection and a further hot water connection. The other two connections are formed according to a previously mentioned arrangements and configurations. As a result, in the manner described above, cold water and hot water lines can be connected to each of the two connections, so that the water can be conducted from a cold water or hot water connection to the further cold water or further hot water connection. This allows a looping through of the water of the hot or cold water line, without the water must flow through the waste water connection.

According to a further embodiment, the two cold water connections and the two hot water connections are each part of a pipe connection piece, which is fluidically coupled to the waste water connection. By way of example, the pipe connecting piece is a double connecting piece which is fluidically coupled to the sewage connection via a third connection. The pipe fittings may be part, in particular an integral part of the rinsing station. The pipe connector is designed for example as a fitting. The pipe connector may be referred to as a through-hole fitting.

Preferably, the two cold water connections and the two hot water connections are each fluidly connected via a U-shaped pipe section. Thus, the water can be looped through the U-shaped pipe section from the first cold water connection to the second cold water connection, without this must necessarily drain over the further connection of the pipe connector and the waste water connection. Due to the U-shaped pipe section a continuous pipe run between the two cold water connections or both hot water connections is achieved. This contributes to lower pressure losses in the pipe connector when, for example, a medium such as water, is passed through the two cold water connections or hot water connections.

According to a further embodiment, the rinsing station has a housing, wherein the cold water connection and the hot water connection or the two cold water connections and the two hot water connections are arranged within the housing. Alternatively or additionally, the waste water connection of the rinsing station is arranged within the housing. In other words, the connections are encapsulated and / or enclosed in the housing of the rinsing station. This contributes to a particularly compact design of the rinsing station. For example, the housing of the rinsing station for the terminals each have a cylindrical recess, can be introduced via the pipes into the interior of the rinsing station to connect them to the corresponding terminals. Such an arrangement also contributes to a simpler and safer transport without damaging the cold or hot water connections. Furthermore, it helps to ensure that the connections on the construction or assembly are not physically damaged by contact with other objects.

Furthermore, a series piping system and a loop system for a building will be described. Each system has a hot water pipe and a cold water pipe as well as one or more consumers, which are connected to the hot water pipe and / or cold water pipe. Furthermore, each system has in each case a rinsing station according to one of the aforementioned embodiments, which is arranged in or on a wall of the building. The hot water pipe and the cold water pipe are connected to the cold water connection and the hot water connection of the rinsing station via an underside of the rinsing station facing the floor of the building.

Such systems essentially allow the aforementioned advantages and functions. In particular, pipelines are only over the bottom of the rinsing station connected to the rinsing station, so that the pipes can be laid by the shortest route of the rinsing station.

Further advantageous embodiments are disclosed in the following detailed description of an embodiment.

The embodiment will be described below with reference to the attached figures. Similar or equivalent elements are provided across the figures with the same reference numerals.

a view of the rinsing station.

FIG. 1 shows a schematic, perspective view of a not fully shown loop system 1 for a floor of a building. In FIG. 1 is exemplified a bathroom.

The loop system 1 comprises a plurality of consumers 2, namely a toilet 3, a shower 4 and a sink 5. The consumers 2 are fluidly connected to a cold water pipe 6 and / or a hot water pipe 7.

The cold water line 6 and the hot water line 7 are connected via valves 14 and / or faucets to a cold water riser 10 and hot water riser 11. The cold water riser 10 and the hot water riser 11 are main lines of a building and usually run from a house connection vertically on different floors of the building. The cold water pipe 6 and the hot water pipe 7 are mainly laid in a vicinity of a floor 12 of the bathroom.

In the exemplary embodiment, the cold water line 6, starting from the cold water riser 10 leads to a cistern 9 of the toilet 3. From the toilet 3, the cold water pipe 6 is further led to a mixing valve 8 of the shower 4. From the shower 4, the cold water line 6 to a rinsing station 13, which can also be referred to as Hygienespülstation out. The cold water line 6 is then passed from the rinsing station 13 to a mixing valve 8 of the wash basin 5. Then the cold water pipe 6 is guided in a further room of the building and returned from this to a beginning of the loop system 1 (ie in the flow direction behind the valves 14 in front of the consumer 2), for example to a branch (not shown).

The situation is similar with the hot water pipe 7. The hot water pipe 7 is performed starting from the hot water riser 11 after the valve 14 directly to mixing valve 8 of the shower 4. From the shower 4, the hot water pipe 4 is led directly to the mixing valve 8 of the washbasin 5 and from there to the rinsing station 13. Starting from the rinsing station 13, the hot water pipe is the sixth performed in the other room of the building and returned to the beginning of the loop system 1 analogous to the cold water pipe 6.

The water pipes 6 and 7 are connected to the consumer 2 so that they are forwarded from one consumer to the next consumer or sanded through. To the mixing valves 8 and to the rinsing station 13, the lines 6, 7 via pipe fittings 15, which may also be referred to as double fittings or pass-through pieces connected. Via a pipe connector 15, the respective hot or cold water line 6, 7 is forwarded directly to the next consumer 2, without the respective consumer 2 must be operated.

As described above, the entire loop system 1, ie the entire cold water line 6 and / or the hot water line 7 is now flushed by an operation of a consumer 2, so that stagnation areas in the lines 6 and 7 are avoided. For example, 4 hot water and cold water is flushed via lines 6 and 7 from both directions to the shower 4 when you press the shower.

In order not to give the flushing of all lines exclusively in human hands, the rinsing station 13, is provided. This ensures that flush the loop system 1, if none of the consumer 2 is operated and thus the water would normally be in the lines 6 and 7 would be stopped.

The rinsing station 13, which is arranged in a wall of the bathroom is based on Figures 2 and 3 detailed described. FIG. 2 shows a part of the FIG. 1 , which represents the rinse station 13 enlarged. FIG. 3 shows the rinsing station 13 alone in a front view.

The rinsing station 13 has a housing 16 in which a plurality of components of the rinsing station 13 are arranged. As an example, a power supply unit 17 for connection to a power grid of the building is mentioned. Furthermore, for example, a control device 18 (also called control unit) is provided. The rinsing station 13 has two pipe fittings 15, each having two cold water connections 19 and two hot water connections 20. Each pipe connector 15 has a third connection, via which it is fluidically coupled to a waste water connection 21 of the rinsing station 13. Between every third connection of a pipe connection piece 15 and the waste water connection 21, valves 22 are fluidically arranged, which can be electrically controlled by means of the control device 18. The cold water connections 19 or the hot water connections 20 are fluidically coupled via a U-shaped pipe section of the corresponding pipe connection piece 15. The waste water connection 21 is fluidically coupled to an (upstream) safety device 23, so that the water flows out via this and the wastewater connection via a sewage system. In other words, the sewage connection 21 can be connected or connected to a sewage system. In the event of blockage of the drain, the safety device 23 prevents the water from flowing back into the cold water or hot water lines 6, 7. Furthermore, the flushing station 13 has one or more sensors (not shown), for example a temperature or a volume flow of the hot or cold water Cold water pipe 6, 7 measure.

The safety device 23 and the sewage connection 21 can also be regarded as a unit, for example, a sewage component.

Normally, the valves 22 are closed. However, if predetermined conditions occur, for example when a certain hot water temperature has fallen below, the control device 18 opens one or both valves 22 so that water can flow away via the waste water connection 21. In another example, the controller 18 briefly opens the valves 22 after 72 hours without operating a consumer 2. In other words, an automatic forced flushing takes place. As a result, the stagnation regions described are avoided since all sections of the lines 6, 7 are flushed through.

As based on the FIGS. 1 to 3 it can be seen, all ports 19 and 20 and 21 a bottom 24 of the rinsing station 13 are assigned. This requires that all pipes and the drain via the bottom 24 are connected to the flushing station 13 and fluidly coupled. In particular, rotational symmetry axes 25 of the connections 19, 20 and 21 run parallel to one another. Openings of the ports 19, 20 and 21 face a common, imaginary plane 26. The plane 26 runs parallel to the floor 12.

The rinsing station 13 allows the advantages and functions mentioned above.

As already mentioned, the cold and hot water pipes 6 and 7 are typically laid near the ground. When installing the flushing station 13, the lines 6 and 7 are only perpendicular to the bottom 12 to the bottom 24 of the rinsing station 13 out. It is thus not necessary, for example, to lead the hot or cold water line 6, 7 around the housing 13 of the rinsing station 13 to an upper side 27 of the rinsing station 13. This would unnecessarily require longer pipelines, which increases material and assembly costs. Furthermore, the wall would have to be left significantly more comprehensive. The rinsing station 13 can thus be efficiently, for example, mounted quickly on a construction site.

The cold water and hot water connections 19 and 20 are arranged in the interior of the housing 16 of the rinsing station 13. This has the advantage that the rinsing station 13 is very compact and, prior to assembly, that is to say the operational installation of the rinsing station 13, no connections 19, 20 protrude out of the housing 16. This protects against physical damage and also facilitates transport, for example with regard to stackability. Alternatively or additionally, the wastewater component (see above) is encapsulated in the housing 16. In other words, the waste water connection 21 is encapsulated in the housing 16 or surrounded by a cover of the housing 16 or the rinsing station 13, so that none of the connections 19, 20, 21 protrudes from the rinsing station via the underside.

Instead of in FIGS. 1 to 3 a loop line system can also be installed, it being ensured that the rinsing station 13 is connected at the last point to the cold or hot water line 6 and 7, for example, after all consumers of the series conduit system.

The invention is not limited by the illustrated embodiment. For example, the Flushing station 13 in other rooms or rooms than the bathroom described. Also, different or differently configured pipe connectors 15 can be used. It is essential that the ports 19, 20 21 of the rinsing station 13 of the bottom 24 are assigned.
