Description

The invention relates to a flushing station for flushing a ring or row line system according to the preamble of patent claim 1.

Nowadays it is common to install row or ring pipe systems when laying water pipes.

Typically, in a row pipe system, hot water and / or cold water pipes are routed from consumer to consumer in a room of a building or on a floor of a building. A last consumer of the consumers connected in series should be a frequently used consumer, for example a wash basin of a bathroom. This ensures that when this last consumer is used, water is flushed through all the upstream pipe sections of the cold water and / or hot water pipes in the room or on the floor (floor). In this way, stagnation areas can be avoided in pipe sections in which existing water is not or only rarely moved or flushed, such as, for example, in the case of a bathtub which is not used very often. Such stagnation areas would often cause hygienic deficiencies, particularly due to the formation of bacteria (e.g. legionella).

In the case of ring pipe systems, in addition to the row pipe systems, cold water or hot water pipes are run by the last consumer at the beginning of the Row line laid. This creates a pipe ring for the cold water or hot water pipes. This has the advantage that with every use of whatever consumer water flows from both directions to the consumer, and therefore irrespective of the actuation of a consumer connected to the ring line, all pipeline sections are always flowed through.

In the line systems described above, additional flushing stations can be used, which further improve the hygiene of such systems. Typically, a flushing station is installed in a row or loop system and flushes it automatically. This is particularly advantageous if the row or ring line system is not operated for a long time, for example if an apartment, a house or a section of a building is empty for a long time.

The US 2005/274812 A1 relates to a water flushing system for the automatic maintenance of water quality in water supply systems.

The DE 20 2014 105702 U1 relates to a sanitary arrangement in which a flushing line with an electrically controllable flushing valve and a control unit for controlling the electrically controllable flushing valve are provided.

The WO 2014/040823 A1 relates to a water fitting for performing a hygiene flush in a water installation.

The EP 1 964 983 A1 relates to a device for automatic rinsing of water pipes, with at least a valve connected to a water pipe and a control with which the valve for flushing the water pipe is opened and closed.

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

This object is achieved by a flushing station for flushing a ring or row line system with the features of claim 1. The row or ring line system is set up for a drinking water installation, for example. The rinsing station has a housing in which a cold water connection for connecting a cold water line and a hot water connection for connecting a hot water line are arranged. The rinsing station also has a waste water connection. The cold water connection and the hot water connection are fluidly coupled to the waste water connection. The rinsing station is characterized in that the cold water connection, the hot water connection and the waste water connection are assigned to an underside of the rinsing station.

The fact that all connections of the flushing station are assigned to a common side of the flushing station means that the flushing station can be fluidly coupled to pipes via only the common side. In other words, pipelines such as cold water, hot water and drain or waste water pipes are connected to the flushing station only via the common side or are fluidly coupled. In other words, said connections can be fluidically connected from a common side. For example the rinsing station is piped only on the common side of it.

The common side is preferably the underside of the rinsing station, with “below” meaning that this side is assigned to a floor, in particular facing.

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

Typically, cold and hot water pipes are laid in a floor of a floor of a building or at least close to the floor and are led from bottom to top (against the direction of gravity) to built-in consumers such as wash basins or the like. Because all connections are assigned to the underside of the flushing station, the pipelines can thus be routed in the shortest possible way perpendicular to the floor to the flushing station. Another advantage is that especially in brick or solid walls, particularly few recesses have to be provided or made for the laying of the pipes to the flushing station. In particular, are only at the common side of the flushing station one or more suitable recesses for the lines necessary. The lines can thus be efficiently connected to the flushing station. This can save considerable time and thus assembly costs, especially on a construction site.

In addition, the rinsing station has a housing, the cold water connection and the hot water connection or two cold water connections and two hot water connections (see below) being arranged within the housing. The wastewater connection of the rinsing station is optionally arranged inside 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 flushing station for the connections each has a cylindrical recess, via which pipes can be introduced into the interior of the flushing station in order to connect them to the corresponding connections. Such an arrangement also contributes to a simpler and safer transport without the cold or hot water connections being damaged. It also helps to ensure that the connections on the construction or assembly are not physically damaged by contact with other objects.

According to one embodiment, the cold water connection, the hot water connection and the waste water connection are essentially open to a common level. The common level is opposite the common side of the washing station. The common level is, for example, a floor of a room of the building in an assembled state. The common level can also be an imaginary level, for example all openings of the connections described opposite the flushing station. It is not absolutely necessary for cross sections of the openings to be arranged parallel to the common plane. Rather, it is also possible that the cross sections of the openings of the connections are arranged at a certain angle to the common plane. In other words, all cross sections of the openings of the connections or of the connection pipe are oriented at an angle of less than 90 ° to the common plane. This contributes to efficient assembly.

According to a further embodiment, the cold water connection, the hot water connection and the waste water connection point essentially in the same direction. The direction is to be considered vectorially. In other words, the connections and the waste water connection point in one direction away from the common side of the flushing station. This contributes to efficient assembly.

According to a further embodiment, the longitudinal axes of the cold water connection, the hot water connection and the waste water connection are aligned essentially parallel to one another. At least in the area of the openings of the connections, the longitudinal axes run essentially parallel to one another. Essentially parallel means that the longitudinal axes not only run exactly parallel, but can also be aligned with one another with a slight angular deviation, 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 makes it compact and allows space-saving laying of pipes. This contributes to the fact that only small recesses have to be provided in walls or masonry.

According to a further embodiment, the above-mentioned longitudinal axes run in a common plane. As a result, the lines are laid and connected to the flushing station on a common level.

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

Alternatively or additionally, the connections can also comprise an internal or an external 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 two other connections are designed in accordance with a previously mentioned arrangements and configurations. As a result, cold water and hot water pipes can be connected to both connections in the manner described above, so that the water can be directed from a cold water or hot water connection to another cold water or further hot water connection. This enables water to be looped through the hot or cold water pipe without the water having to run off via 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 fluidly coupled to the waste water connection. The pipe connection piece is, for example, a double connection piece which is fluidly coupled to the waste water connection via a third connection. The pipe connectors can be part, in particular an integral part, of the rinsing station. The pipe connector is designed, for example, as a fitting. The pipe connector can be referred to as a loop-through fitting.

The two cold water connections and the two hot water connections are preferably fluidly connected via a U-shaped pipe section. The water can thus be looped through the U-shaped pipe section from the first cold water connection to the second cold water connection without this necessarily having to flow off via the further connection of the pipe connection piece 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, for example, if a medium such as water, over the two Cold water connections or hot water connections is passed through.

Furthermore, a row line system and a ring line system for a building are described. Each system has a hot water pipe and a cold water pipe and several consumers that are connected to the hot water pipe and / or cold water pipe. Furthermore, each system has a flushing station according to one of the aforementioned configurations, 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 washing station via a bottom side of the flushing station facing a floor of the building.

Such systems essentially enable the aforementioned advantages and functions. In particular, pipelines are only on the underside of the rinsing station connected to the flushing station so that the pipes can be laid in the shortest possible way to the flushing station.

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

The exemplary embodiment is described below with reference to the attached figures. Elements of the same type or having the same effect are provided with the same reference symbols in all figures.

Figure 1 shows a schematic, perspective view of a ring line system 1 for a floor of a building, which is not shown completely. In Figure 1 a bathroom is shown as an example.

The ring line system 1 comprises several consumers 2, namely a toilet 3, a shower 4 and a wash basin 5. The consumers 2 are fluidly connected to a cold water line 6 and / or a hot water line 7.

The cold water line 6 and the hot water line 7 are connected via valves 14 and / or line taps to a cold water riser line 10 or hot water riser line 11. The cold water riser pipe 10 and the warm water riser pipe 11 are main pipes of a building and generally run vertically from a house connection over different floors of the building. The cold water pipe 6 and the hot water pipe 7 are predominantly installed in the vicinity of a floor 12 of the bathroom.

In the exemplary embodiment, the cold water line 6 leads from the cold water riser line 10 to a cistern 9 of the toilet 3. From the toilet 3, the cold water line 6 is led further to a mixer tap 8 of the shower 4. The cold water line 6 is led from the shower 4 to a rinsing station 13, which can also be referred to as a hygiene rinsing station. The cold water line 6 is then passed from the rinsing station 13 to a mixer tap 8 of the wash basin 5. Thereupon, the cold water line 6 is routed in a further room of the building and from this to a beginning of the ring line system 1 (that is, downstream of the valves 14 in front of the consumers 2), for example to a branch (not shown).

The situation with the hot water line 7 is similar. Starting from the hot water rising line 11 after the valve 14, the hot water line 7 is led directly to the mixer tap 8 of the shower 4. From the shower 4, the hot water line 4 is led directly to the mixer tap 8 of the wash basin 5 and from there to the rinsing station 13. Starting from the rinsing station 13, the hot water line 6 similar to the cold water line 6 led into the other room of the building and returned to the beginning of the ring line system 1.

The water pipes 6 and 7 are connected to the consumer 2 such that they are passed on from one consumer to the next consumer or looped through. The lines 6, 7 are connected to the mixing fittings 8 or to the flushing station 13 via pipe connecting pieces 15, which can also be referred to as double connecting pieces or loop-through pieces. The respective hot or cold water line 6, 7 is forwarded directly to the next consumer 2 via a pipe connector 15, without the respective consumer 2 having to be actuated.

As described at the beginning, the entire ring line system 1, that is to say the entire cold water line 6 and / or the hot water line 7, is now flushed through when a consumer 2 is actuated, so that stagnation areas in the lines 6 and 7 are avoided. For example, when the shower 4 is actuated, hot water and cold water are rinsed to the shower 4 from both directions via the lines 6 and 7.

The rinsing station 13 is provided in order not to admit that all the lines have been rinsed through entirely by human hands. This ensures that the ring line system 1 is flushed through when none of the consumers 2 is actuated and the water in the lines 6 and 7 would normally stand still.

The rinsing station 13, which is arranged in a wall of the bathroom, is based on Figures 2 and 3rd more detailed described. Figure 2 shows a section of the Figure 1 , which shows the flushing station 13 enlarged. Figure 3 shows the flushing station 13 alone in a front view.

The rinsing station 13 has a housing 16 in which several components of the rinsing station 13 are arranged. A power supply unit 17 for connection to a power network of the building may be mentioned as an example. Furthermore, a control device 18 (also called a control device) is provided, for example. The rinsing station 13 has two pipe connectors 15, each having two cold water connections 19 and two hot water connections 20. Each pipe connection piece 15 has a third connection, via which it is fluidly coupled to a waste water connection 21 of the rinsing station 13. Valves 22, which can be electrically controlled by means of the control device 18, are fluidly arranged between every third connection of a pipe connection piece 15 and the waste water connection 21. The cold water connections 19 or the hot water connections 20 are fluidly coupled via a U-shaped pipe section of the corresponding pipe connection piece 15. The waste water connection 21 is fluidly coupled to a (upstream) safety device 23, so that the water flows through it and the waste water connection via a waste water system. In other words, the waste water connection 21 can be connected or connected to a waste water system. In the event of a blockage in the drain, the safety device 23 prevents the water from flowing back into the cold water or hot water lines 6, 7. Furthermore, the rinsing station 13 has one or more sensors, not shown, which, for example, detect a temperature or a volume flow of the hot or Measure cold water pipe 6, 7.

The safety device 23 and the waste water connection 21 can also be viewed as a unit, for example a waste water component.

The valves 22 are normally closed. However, if predetermined conditions occur, for example if a certain hot water temperature is fallen below, the control device 18 opens one or both valves 22 so that water can flow off via the waste water connection 21. In another example, the control device 18 opens the valves 22 briefly after 72 hours without actuation of a consumer 2. In other words, automatic forced rinsing takes place. This avoids the stagnation areas described, since all sections of the lines 6, 7 are flushed out.

As with the Figures 1 to 3 it can be seen that all connections 19 and 20 and 21 are assigned to an underside 24 of the washing station 13. This means that all pipelines and the drain are connected to the flushing station 13 via the underside 24 or are fluidly coupled. In particular, axes of rotational symmetry 25 of the connections 19, 20 and 21 run parallel to one another. Openings of the connections 19, 20 and 21 face a common, imaginary plane 26. The plane 26 runs parallel to the floor 12.

The rinsing station 13 enables the advantages and functions mentioned at the beginning.

As already mentioned, the cold and hot water pipes 6 and 7 are typically installed close to the ground. When installing the rinsing station 13, the lines 6 and 7 are only led perpendicular to the bottom 12 to the bottom 24 of the washing station 13. It is therefore not necessary, for example, to lead the hot or cold water line 6, 7 around the housing 16 of the washing station 13 to an upper side 27 of the washing station 13. This would necessitate longer pipelines, which increases material and assembly costs. Furthermore, the wall would have to be cut out significantly more comprehensively. The flushing station 13 can thus be installed efficiently, for example quickly, on a construction site.

The cold water and hot water connections 19 and 20 are arranged inside the housing 16 of the rinsing station 13. This has the advantage that the rinsing station 13 is very compact and no connections 19, 20 protrude from the housing 16 before the assembly, that is to say the operational installation of the rinsing station 13. This protects against physical damage and also makes transportation easier, for example with regard to stackability. Alternatively or additionally, the waste water 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 flushing station 13, so that none of the connections 19, 20, 21 protrude from the flushing station via the underside.

Instead of the in Figures 1 to 3 described ring line system 1, a row line system can also be installed, it being important to ensure that the flushing station 13 is connected last to the cold or hot water line 6 and 7, for example after all consumers of the row line system.

The invention is not limited by the embodiment shown. For example, the Flushing station 13 also in rooms or rooms other than the bathroom described. Different or differently designed pipe connectors 15 can also be used. It is essential that the connections 19, 20 21 of the rinsing station 13 are assigned to the underside 24.
