Sink unit with built-in water distribution device and a

Sink unit, which has fastening means.

Background of the invention

German Offenlegungsschrift DE 10 2010 001 086 A1 discloses a

Domestic water distribution station for connection to a main water connection. This domestic water distribution station can be made of single components

Replace domestic water system. It includes an input port, a water filter, multiple manifold segments with output ports for connecting

Domestic water pipes, as well as manually operable valves. This device is not intended for installation in a sink cabinet but for connection to the main water supply of a house.

The German patent application DE 36 04 324 A1 discloses an installation wall element with a plate-shaped rear wall and a plate-shaped front wall, between which pipes and pipe sections for water supply lines and

Water disposal lines are attached. Such a wall element is provided as a prefabricated component for wet cells. The disclosed wall element is characterized in that it can be prefabricated and still allows adaptation to different connection geometries.

European Patent EP 0 175 299 B1 discloses a multiple siphon for

Fitted kitchens for connecting several used water sources. The siphon is essentially cube-shaped and has several chambers that allow an odor finish for multiple waste water sources in a particularly compact design. In addition, the siphon can be combined with a cold and hot water distributor, but which have no control valves.

German Offenlegungsschrift DE 103 17 071 A1 discloses an auxiliary installation framework for sanitary installations for installation in a sink cabinet. On a rectangular subframe from frame struts, among other things, a siphon, two angle valves and pressure-resistant connection hoses are arranged, which can be connected to water supply lines for hot and cold water and distribute the water to over-table outlet fittings and other water consumers.

The problem underlying the invention

The invention is based on the object, a use of a

Water distribution device in a sink unit for distributing

Indicate drinking water to domestic appliances. In particular, by the use of a water distribution device a drinking water distribution in a sink unit cabinet should be particularly space-saving and easy to implement.

The invention is also based on the object, an improved

Provide water distribution device for installation in a sink cabinet. Furthermore, the invention has the object, an improved

To provide sink cabinet with built-in water distribution device.

In addition, an improved sink cabinet, which has fastening means to be provided. Inventive solution

The reference numbers in all claims have no limiting effect, but are only intended to improve their readability.

To solve the problem, the invention proposes the use of a

Water distribution device (WVV) in a sink cabinet for distributing drinking water to household appliances with water, wherein the WVV comprises at least: fastening means for mounting on a wall in the sink cabinet; a supply water input ready for connection to a water supply line; a plurality of device water outlets ready to be connected; a filter water outlet and a filter water inlet for connecting a water filter, wherein the

Supply water inlet is connected via a drinking water line with the filter water outlet to feed the water filter with water, and the filter water inlet is connected via at least one filter water line to the plurality of device water outlets to feed the device water outlets with water coming from the filter water inlet.

As water-conducting household appliances, hereinafter also referred to as devices for simplicity, devices are understood to have at least one water connection. Such devices are available for private or professional use.

Water-conducting household appliances are used for example for drinking water treatment and in this case have a drinking water inlet and a

Drinking water output. These include, for example, water filters, water softeners,

Carbonizers and water coolers and hot water boilers. Appliances that consume drinking water have a drinking water inlet and usually also one

Used water outlet. These include, for example, dishwasher and

Washing machines and sinks with faucet and drain. Devices without water outlet in the sense of a utility water drain are for example coffee machines,

Water dispensers, steam cleaners, garden hoses or lawn sprinklers. in the

Sink unit must therefore be installed a variety of drinking and utility water pipes. The latter are usually closed by a siphon against the escape of unwanted odors.

A fastener according to the invention is a supporting element of the WVV, with which the water inlets, water outlets and water pipes of the WVV are connected, so that a unit arises from these components, wherein individual components can be detachably and / or movably connected. Components may be connected to the fastener directly or via another component. In particular, water inlets and / or water outlets may be movably connected to the fastener. For example, a water inlet and / or water outlet may be formed as a movable end of a flexible pipe or hose fixedly or detachably connected to the fastening means on one side. Furthermore, a fastening means comprises holes or fastening loops, so that the WVV can be mounted with screws on a wall, for example. A fastening means is for example a frame, a plate or a housing.

For the purposes of the invention, water can flow in via a water inlet and drain off via a water outlet or water drain. For the purposes of the invention, water flows from a water inlet via a water pipe or through a water-bearing

Home appliance to a water outlet or water drain.

For the purposes of the invention, water pipes are rigid or flexible elements that can carry water and contain branches. Water pipes are for example pipes or pipe pieces or hoses or a combination of pipes and hoses.

Branches are realized, for example, by tees to which pipes or hoses are connected.

For the purposes of the invention "ready for connection" means that the relevant

Water inlet or water outlet is not yet connected to a water pipe or a device. In this case, "ready to be connected" does not preclude the need to make preparations at the respective water inlet or outlet, for example, it may be necessary first to remove a cap or to attach an adapter or to make another preparation to the intended water line or to connect a device

Connecting prepared water inlets or water outlets of the WVV is still accessible even if the WVV is mounted in the sink unit.

A water filter is a device for changing the water quality. In most cases, particles contained in the water, such as suspended solids or microorganisms or substances dissolved in the water, are removed or their concentration lowered.

For example, water filters serve to enhance the smell and taste of the water improve and / or reduce the hardness of the water. The function of the

Water filters can be based on mechanical, physical-chemical or biological effects or on a combination of several aforementioned effects.

Drinking water installations are usually housed in sink vanity units. The sink unit cabinet is usually placed in the immediate vicinity of a building-side water supply and a waste water drain. The building-side water supply lines are usually provided with corner valves for connecting a drinking water installation. In addition to the drinking water installation usually a variety of water-conducting household appliances is housed in the sink cabinet. Furthermore, the sink cabinet is often to provide space for a garbage container and cleaning agents. With a standard width of the sink unit of 60 cm, the available space is quickly used up. Therefore, it is advantageous to make the drinking water installation particularly space-saving.

According to the state of the art, when installing a drinking water installation, individual components such as tees, valves and water pipes are successively assembled and installed in the sink unit. The installation is time-consuming and requires considerable planning effort, since all items must be known and available before installation and is usually feasible only by a professional. Such a drinking water installation can possibly be confusing, space consuming and

be susceptible to damage. These possible disadvantages are avoided by the invention by using a WVV in a sink cabinet. The WVV combines as described above a variety of components on a fastener, so that the WVV as a compact unit with ready to connect water inputs and

Water outlets is present. The achievable advantage of the use of a WVV is that a particularly space-saving and clear drinking water distribution is made possible and also the assembly is easy to carry out, whereby time and costs are saved.

To achieve the object, the invention also proposes the use of a WVV for connection to a water filter for distributing filtered drinking water to water-conducting household appliances. For this use, the WVV includes at least fasteners for mounting on a wall, a filter water inlet for

Connecting a water filter and a plurality for connecting ready

Appliance water outlets, where the filter water inlet via at least one

Filter water line is connected to the plurality of appliance water outlets to the Supply unit water outlets with water coming from the filter water inlet. Since the use of the WVV provides for connection to a water filter, the WVV does not have an integrated water filter. As a result, the WVV can advantageously be constructed particularly simple and compact. Preferably, the WVV is used in a sink cabinet. Particularly preferably, the water filter is also installed in the sink cabinet, so that the WVV can advantageously be particularly easily connected to the water filter.

The solution of the task succeeds out, however, by a WVV for installation in a sink unit cabinet, the attachment means for mounting the WVV on a wall in the sink cabinet and prepare for connection

Supply water inlet and a plurality to connect ready

Device water outlets has. The WVV also includes: a filter water outlet and a filter water inlet for connecting a water filter, the

Furthermore, the object is achieved by providing a sink unit, in which the aforementioned WVV is installed.

The solution of the problem is achieved by putting off by providing a

A sink cabinet having attachment means to which a WVV can be attached, the WVV having a supply water inlet ready for connection to a water supply line, a plurality for connection

Equipment water outlets, a filter water outlet and a filter water inlet for connecting a water filter, the supply water inlet is connected via a drinking water line with the filter water outlet to feed the water filter with water, and the filter water inlet over at least one

Filter water line is connected to the plurality of appliance water outlets to feed the appliance water outlets with water coming from the filter water inlet. Preferred embodiments of the invention

In a preferred use of a water distribution device, the drinking water to be distributed has a temperature of less than 20 degrees Celsius, more preferably less than 15 degrees Celsius, even more preferably less than 10 degrees Celsius. Preferably, a supply water inlet of the WVV is connected via a water pipe to a building-side cold water connection. Connected household appliances such as a water filter, a drinking water cooler, a carbonator or a coffee machine usually need to be charged with cold water. An achievable advantage is that the components of the WVV at

Use with cold water are spared and therefore less prone to damage. Another achievable advantage is that the WVV can be used without a thermostat. As a result, the WVV can be less complex in construction and cheaper to manufacture.

In a preferred use of a WVV the drinking water to be distributed is at a pressure of less than 8 bar at the supply water inlet. Preferably, the WVV is therefore designed so that water can be distributed with a pressure of less than 8 bar without damaging the WVV. Particularly preferably, the WVV for distributing drinking water, which with a pressure of less than 5 bar from the

Water supply is used. In particular, use of the WVV is preferred in which the pressure of the water coming from the building water supply line does not have to be reduced. A preferred WVV therefore does not include a pressure reducer. Particularly preferably, the WVV does not include safety valves. As a result, the advantage can be achieved that the WVV is cheaper. However, this does not exclude that the building-side water installation includes pressure reducers and / or safety valves. In an alternative use of the WVV to connect to a

Water supply, is supplied from the drinking water with a higher pressure of the WVV, the WVV includes a pressure reducer, preferably between the

Supply water inlet and the drinking water pipe of WVV is mounted. In a further alternative embodiment, the WVV includes a pressure reducer, which is preferably mounted between the filter water outlet and the drinking water line of the WVV, to the water filter as well as devices that are fed with filtered water against

To protect pressure surges, which can be caused for example by a connected to a water outlet of the WVV dishwasher. Thereby the advantage can be obtained that the water-conducting household appliances, which at the following Device water outlets are connected, are particularly protected against pressure surges that can adversely affect the operation of the device and / or damage the devices and water pipes.

In a preferred embodiment of the WVV according to the invention, the filter water outlet is ready for connection. This means that no water pipe or device is connected to the filter water outlet. In the same way, the filter water inlet is preferably ready for connection. Particularly preferred are filter water inlet and

Filter water outlet ready for connection. An alternative preferred development of the WVV comprises a water filter, wherein the water inlet of the water filter is connected to the filter water outlet of the WVV and the water outlet of the water filter is connected to the filter water inlet of the WVV. In this embodiment, the water filter is preferably attached to the common fastening means of the WVV.

Preferably, it is an activated carbon filter, particularly preferably an ion exchanger. Particularly preferably, a combination of activated carbon filter and ion exchanger is used with fine particle filter. The water filter is preferably designed to liberate the water coming from the building-side water supply from undesirable odors or tastes, impurities or germs. Particularly preferably, the water filter lowers the degree of hardness of the water. Of the

Water filter is preferably arranged so that when the WVV in the

Sink unit is built-in, making it possible to replace one

Filter cartridge is possible without removing the WVV. By integrating the

Water filter in the WVV can be achieved the advantage that the drinking water installation is even more space-saving and clear. In an alternative embodiment of the invention, the water filter at another location in the sink cabinet

be arranged and connected only via connecting lines to the filter water inlet and - output. This arrangement may have the advantage that the

Drinking water installation can be better adapted to the conditions of the sink unit. In a further alternative embodiment, the filter water inlet without a detour via a water filter directly with the filter water outlet, for example by a piece of hose or a piece of pipe, be shorted. In such an embodiment, therefore, no water filtration is provided. This is for example advantageous if already pretreated water from the building water supply line comes or if the untreated water already has a sufficiently low degree of hardness. Preferably, the fastening means of the water distribution device are formed as a closable housing. Preferably, a predominant part of the water-carrying components, in particular the water pipes, in the interior of the

Housed housing. Particularly preferably, a removable cover is provided, which is preferably transparent. Preferably, all connections are accessible from the outside, ie without removing the cover, so that water pipes can be connected to the terminals. For the mounting of the fastening means on a wall, which is preferably located in a sink cabinet, the fastening means preferably has eyelets or other connecting element. Preferably, the WVV can be fastened by means of screws through the eyelets on a wall. A wall may be part of the sink cabinet or a building side wall located behind the sink unit cabinet, which is through the

Sink unit is accessible. Alternatively, instead of on a wall, it may also be advantageous to attach the WVV to the bottom or to a bottom of the top cover in the interior of the sink table. A lockable housing has the achievable advantage that all components of the WVV are particularly protected against damage before, during and after installation.

In a preferred version of the WVV, at least three appliance water outlets are connected to the filter water inlet via the filter water line. Especially

Preferably, at least five appliance water outlets are connected to the filter water inlet via the filter water line. Filtered water is preferred because it has improved taste and avoids calcification of the attached equipment. A variety of device water outlets advantageously allows the connection of many devices without the use of tees, which the

Drinking water installation otherwise confusing and susceptible to damage.

Preferably, a device water outlet is used to connect a fitting. A preferred fitting is a DVGW-approved safety fitting.

A preferred WVV includes at least one additional water outlet for unfiltered water, which is connected to the supply water inlet via the drinking water line. This water outlet is also referred to below as a service water outlet and is provided, for example, for connecting a dishwasher and / or a washing machine. These machines can also be operated with unfiltered or undecalcified water. Preferably, they have their own Wasserentkalkungseseinchtungen The achievable advantage of another connection for unfiltered water is that the time interval between replacing the water filter or a

Filter cartridge is extended, whereby time and cost can be saved.

In a preferred WVV, at least one appliance water outlet has a shut-off valve with which the water flow through the appliance water outlet can be regulated. As a result, the flow rate of a device water outlet can advantageously be limited. The shut-off valve can preferably be operated by hand. Particularly preferably, the shut-off valve is a shut-off valve, for example a ball valve. The achievable advantage here is that the device water outlet is particularly easy to close and reopen, which can be an advantage when maintaining a device or changing a connection, since not the entire water supply must be closed and also dispense with the use of blind plugs can.

An alternative preferred WVV has no valves. In particular, the WVV preferably does not have shut-off valves which are preferably manually operable.

Particularly preferably, the WVV also has no safety and / or pressure relief valves. As a result, it is advantageously achievable to realize a particularly cost-effective and compact WVV since fewer components are used. In particular, a preferred WVV can be operated without the use of electric current. Thus advantageously no power source must be present at the location of use of the WVV.

In a preferred WVV at least one water inlet or outlet has a pipe thread with a nominal diameter of preferably 3/8 inch. Here is the achievable advantage that commercially available water-conducting household appliances without the use of adapters can be connected, as most commercially available

water-bearing household appliances have water connections with screw threads of 3/8 inch nominal width. For the use of devices that have connections of other nominal size, an alternative embodiment of the WVV also has

Water outlets with nominal widths of 1/2 inch and / or 1 inch up. This makes the WVV even more versatile. Preferably, at least one connection is with one

Screw thread or screw fitting for connecting a line provided, for example, as a screw-in or screw-on. Furthermore, particularly preferably at least one connection to a connector, bulkhead connector or a push-in fitting. Preferred materials for connectors or

Fittings are brass, nickel plated brass, stainless steel and / or plastic preferably with food approval, for example POM. A preferred one Connector is straight, particularly preferably angled, again particularly preferably designed as a T-connector. A preferred connector allows you to connect 4 mm, 6 mm, 8 mm, 10 mm, 12 mm, 15 mm, 18 mm, 22 mm or 28 mm diameter leads. Particularly preferably, it can also be Reduzierverbinder, preferably at least two different

Have connection diameter. Particularly preferred connectors are, for example, John Guest. Particularly preferably, at least one water inlet or water outlet can be provided for connection to a line with a bayonet closure. This has the achievable advantage that a connection between a water pipe and a water inlet or water outlet can be made and / or solved very quickly and easily. Deviating from the connectors listed above, other connection systems can be used with the WVV.

In a preferred embodiment of the invention, the WVV comprises a multiple siphon. A multiple siphon is an odor trap that can be used to connect multiple utility water sources. Preferably, the multiple siphon comprises at least two utility water connections, more preferably three

Used water pipes. For example, at the multiple siphon a drain of a sink, a utility water flow of a dishwasher and / or a

Washing machine and a drip water drainage of a Hei ßwasserboilers be connected. A preferred multiple siphon is a tube siphon, preferably

Tube segments comprises, which are preferably releasably attached to each other. A

Tubular design is particularly advantageous because such a multiple siphon can be composed of commercially available standard components. The achievable advantage of integrating the multiple siphon into the WVV is that one particular

space-saving arrangement is created and the multiple siphon is well protected against damage. In addition, a considerable time savings can be achieved during assembly. A preferred multiple siphon also includes an outflow, the

is preferably arranged to be pivotable through 360 degrees, particularly preferably up to 180 degrees, so that depending on installation orientation of the WVV the connection to the building-side wastewater discharge is simplified. This can have the advantage that the multiple siphon is particularly versatile and the assembly is simplified, which in turn saves time. In an alternative embodiment of the invention, the WVV comprises a simple siphon, preferably a water inlet and a Has water drainage. In this embodiment, the WVV can advantageously be particularly compact.

In a further preferred embodiment of the invention, the multiple siphon preferably has a substantially straight, preferably circular cylindrical portion which serves as a waste water inlet to which preferably a substantially consisting of a U-shaped curved tube portion is arranged on which preferably arranged a drain is. Preferably, the curved portion projects out of the fastening means of the WVV such that the curved portion is preferably pivotable through 360 degrees, particularly preferably at least 180 degrees, particularly preferably at least 90 degrees. Preferably, the axis about which the curved portion is pivotable is parallel to the axis of the circular cylindrical portion.

Preferably, all water inlets and water outlets of the WVV with

Labeling provided. Labeling advantageously allows everyone

To mark water inlet and water outlet. This simplifies the identification of the individual water connections.

Preferably, the maximum width of the WVV is less than 55 cm. The maximum width of the WVV refers to a WVV before installation and / or before the connection of appliance or building water pipes. This has the advantage that the WVV fits in a standard sink unit with a typical width of 60 cm.

Particularly preferably, the maximum width of the WVV is less than 45 cm, more preferably less than 30 cm, and even more preferably less than 20 cm. This has the advantage that the water connections are even easier to access.

Preferred water pipes and / or water connections consist of metal and / or plastic, for example stainless steel and / or copper and / or brass and / or PE and / or PVC. In particular, materials are preferred which do not react with water and preferably do not corrode. The achievable advantage of the materials mentioned is that they do not or almost not change the quality of the water. Another possible advantage is that components of the materials mentioned not or only little wear show ß and therefore only after very long intervals of preferably more than 5, more preferably more than 10 years must be maintained. A preferred WVV is characterized by the fact that it manages without hose rupture protection. A particularly preferred WVV dispenses entirely with the use of hoses, in particular pressure-resistant hoses. It has been found that a WVV can advantageously be made particularly compact, if it is preferably composed only of pipe sections and / or fittings. Another achievable advantage is that such a WVV can be particularly stable in terms of their mechanical strength.

Detailed description of the invention with reference to an embodiment

In the following description of a preferred embodiment of the present invention, like reference characters designate like or similar components.

First embodiment

Figure 1 shows a water distribution device 1 (WVV) for use in a

Spültischunterschrank. The illustrated WVV 1 consists of a covered with a transparent lid housing 2, with which the individual components are connected. At the the upper end is a supply water inlet 3, which is intended to be connected to a building-side cold water supply. The supply water inlet 3 is connected via a drinking water line 4 with a filter water outlet 5 at the bottom left and another device water outlet, which is provided as a service water outlet 6 for connecting a dishwasher or a waxing machine. At the

Filter water outlet 5, a pressure reducer 7 is attached, the following

Device water outlets 8, 9 shield against pressure surges caused by the dishwasher. However, the pressure reducer 7 is not absolutely necessary for the use of the WVV. Two of the device water outlets 8 shown are closed with blind plugs 10. A not shown water filter is connected via a line at the output 1 1 of the pressure reducer 7. The filtered water is supplied via a further line at the filter water inlet 12 of the WVV 1 again. The filter water inlet 12 is located behind the filter water outlet 5 and is therefore only partially visible in FIG. About a filter water line 13, the three device water outlets 8, 9 with the

Filter water inlet 12 connected. All water inlets 3, 12 and water outlets 5, 6, 8, 9 described above are defined in the illustrated embodiment by the side walls of the housing 2.

At the top device water outlet 9, a pipe 14 is connected, which leads to a pressure relief valve 15 with a drip tray 16. The output of the

Relief valve 15 is provided for connecting a hot water boiler, not shown. The drip hopper 16 of the pressure relief valve 15 is connected via a

Drip water inlet 18 connected to a multiple siphon 19. The illustrated connection of the pressure relief valve 15 by means of a tube 14 together with the connection of the

Drip water funnel 16 at the multiple siphon 19 leads to a particularly safe and stable arrangement of the pressure relief valve 15. This prevents dripping water from the drip hopper 16 runs into the sink cabinet.

The multiple siphon 19 is fastened with a clamp in the housing 2. About one

Wastewater connection 20 at the upper end of the multiple siphon 19 can be connected to a drain of a sink, not shown. The drain 21 of the

Multiple siphons 19 is pivotally designed so that it can be aligned depending on installation orientation of the WVV 1 in a sink cabinet to a building-side utility water drain. For attachment to a wall in sink unit cabinet, the housing 2 of the WVV 1 mounting lugs 18. At the hot water outlet 6 below a return valve 22 is mounted with a stopcock 23. The return valve 22 prevents polluted water from the dishwasher can penetrate into the drinking water pipe 4. Optionally, shut-off valves, for example ball valves, can be attached to the appliance water outlets 8, 9, which are designed here with pipe threads with a nominal width of 3/8 inch, in order to make each individual appliance water outlet 8, 9 separately closable.

Each water inlet and water outlet of the WVV is provided with labeling means 24, which can be labeled according to the use. Due to the perspective, not all labeling means 24 are visible.

The width of the housing 2 shown is 20 cm. This compact design simplifies installation in a standard sink unit with a width of 60 cm.

The installation of the WVV 1 in a sink unit and the connection of the

Water connections are made in a particularly simple and time-saving manner. The WVV 1 is by means of screws through the eyelets 18 on a wall in

Sink mounted. Using flexible lines with 3/8 inch union nuts, the supply water inlet 3 is first connected to the building-side cold water supply line. Then the connection to the water filter is made with further flexible lines. A DVGW-tested cold water fitting of the sink is connected to one of the unused device water outlets 8. At the output of the pressure relief valve 15, a not shown hot water boiler is connected. At the output of the return valve 22, a not shown dishwasher is connected. With the help of a flexible conduit, a connection between the drain of a sink and the multiple siphon 19 is made and the drain 21 of the multiple siphon 19 is connected via another flexible line after alignment with the utility water drain with this. After closing the remaining device water outlet 8 with a blind plug 10, the cold water supply line can be opened. The WVV 1 is thus ready for operation.

Second embodiment

Figure 2 shows a second exemplary embodiment of the WVV 1, which is intended to distribute exclusively filtered drinking water. Compared to the execution, in Figure 1 is shown, this embodiment has a more compact design. The housing 2 has a width of 16 cm and a height of 1 1 cm. The WVV 1 has a

Filter water line 13 as a continuous line system, which is composed of several bolted brass fittings and pipe sections. The

Filter water line 14 may also be integrally cast from a brass, copper or steel alloy. Instead of brass fittings, for example, stainless steel fittings or plastic fittings can be used. The filter water line 14 has a plurality of terminals which are provided with threads. On the thread plastic connectors are screwed. The exemplary embodiment shown is straight and angled John Guest plastic connectors for 10 mm leads

Diameter. By means of the connectors, cables can become water-carrying

Household appliances are particularly easy and time-saving connected. One of the ports is provided as a filter water inlet 12 for connecting a filter water supply coming from a water filter. About the filter water inlet 12, the filter water line 13 is fed with coming from the filter filtered drinking water. The remaining connections are as device water outlets 8, 9 for connecting

water-bearing household appliances. In contrast to the embodiment shown in Figure 1, this second embodiment has no drinking water pipe

Supply water inlet and filter water outlet on. Instead, the water filter is connected directly via a line to a building-side cold water supply. In addition to the more compact design will be a further improvement over the first

Execution achieved by the arrangement of the multiple siphon 19. The curved U-shaped section is now arranged clearly below the housing 2, as a result of which the drain 21 can be pivoted through 360 degrees. By means of the two fastening loops 18 arranged on the rear side of the housing, the WVV 1 can be fastened, for example, to a wall of a sink unit.

Third embodiment

A third exemplary embodiment of the WVV 1 is shown in FIG. This is a further development of the WVV 1 shown in FIG. 1, which has a similar construction to that of the WVV 1 shown in FIG. 2, since it uses, inter alia, the same housing 2 and the same arrangement of the multiple siphon 19. A

Drinking water pipe 4 with a supply water inlet 3 has a Filter water outlet 5 for charging a water filter with drinking water. A separate from the drinking water pipe 4 filter water line 13 has a filter water inlet 12 through which the WVV 1 is charged with filtered water, which over the

Appliance water outlets 8 can be distributed to water-bearing household appliances. An outflow 21 of the multiple siphon 19 can be pivoted 360 degrees as in the second embodiment, but the curved U-shaped section is not shown in the drawing.

The features disclosed in the foregoing description, the claims and the drawings may be of importance both individually and in any combination for the realization of the invention in its various forms.
