The problem underlying the invention

The invention has for its object to provide a use of a water distribution device in a sink cabinet for the distribution of drinking water to household 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 to provide an improved water distribution device for installation in a sink cabinet. Furthermore, the invention has for its object to provide an improved 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 achieve the object, the invention proposes the use of a water distribution device (WVV) in a sink cabinet for the distribution of drinking water to household appliances with water, 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 for connection; a filter water outlet and a filter water inlet for connection of a water filter, the water inlet being connected to the filter water outlet via a potable water line to provide water to the water filter, and the filter water inlet connected to the plurality of appliance water outlets via at least one filter water line to communicate the appliance water outlets with Filter water inlet to feed incoming water.

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-bearing domestic appliances are used, for example, for drinking water treatment and in this case have a drinking water inlet and a drinking water outlet. These include, for example, water filters, water softeners, carbonators and water coolers and hot water boiler. Appliances that consume drinking water have a drinking water inlet and usually also a used water outlet. These include, for example, dishwashers and washing machines as well as 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 cabinet therefore a variety of drinking and utility water pipes must be laid. 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 is formed 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-conducting household 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 outlet is not yet connected to a water pipe or a device. In this case, "ready for connection" does not exclude that preparations must still be made at the respective water inlet or water outlet. So it may be necessary, for example, first to remove a cap or attach an adapter piece or make another preparation to connect the proposed water pipe or a device. In particular, ready-to-connect water inlets or water outlets of the WVV are 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 improve the smell and taste of the water and / or to reduce the degree of hardness of the water. The function of the water filter 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 angle valves for the connection of a drinking water installation. In addition to the drinking water installation, a large number of water-conducting domestic appliances is usually accommodated in the sink unit. 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, be space consuming and 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 is present as a compact unit with prepared for connection water inputs and water outlets. 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.

The solution of the object is also achieved by a WVV for installation in a sink cabinet, the attachment means for attaching the WVV on a wall in the sink cabinet and a prepared for connection supply water inlet and a plurality ready for connection device water outlets. The WVV also includes: a filter water outlet and a filter water inlet to connect a water filter, the water inlet being connected to the filter water outlet via a drinking water line to provide water to the water filter and the filter water inlet being connected to the plurality of appliance water outlets via at least one filter water line, to feed the appliance water outlets with water coming from the filter water inlet.

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

The solution of the problem is also achieved by providing a sink unit, which has attachment means to which a WVV can be attached, the WVV prepared for connection to a water supply water inlet, a plurality ready for connection device water outlets, a filter water outlet and a filter water inlet to the connection a water filter, wherein the supply water inlet is connected via a drinking water line to 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.

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. 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 are conserved when used with cold water and therefore less susceptible to damage.

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 the distribution of drinking water, which comes with a pressure of less than 5 bar from the water supply line 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 for connection to a water supply, is supplied from the drinking water with a higher pressure of the WVV, the WVV includes a pressure reducer, which is preferably mounted between the supply water inlet and the drinking water line of the WVV. In a further alternative embodiment, the WVV includes a pressure reducer which is mounted between the filter water outlet and the drinking water line of the WVV to protect the water filter and devices that are fed with filtered water against pressure surges, for example, by a dishwasher connected to a water outlet of the WVV can be caused. As a result, the advantage can be achieved that the water-conducting household appliances, which are connected to the following appliance water outlets, are particularly protected from pressure surges that can adversely affect the operation of the devices 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, more preferably an ion exchanger. Most preferably, a combination of activated carbon filter and ion exchanger with fine particle filter is used. 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. The water filter is preferably arranged so that it is accessible when the WVV is installed in the sink cabinet, so that a replacement of a filter cartridge is possible without removing the WVV. By integrating the water filter into the WVV, the advantage can be achieved that the drinking water installation becomes even more space-saving and clearer. In an alternative embodiment of the invention, the water filter may be arranged at a different location in the sink cabinet and connected only via connecting lines to the filter water inlet and outlet. This arrangement can have the advantage that the drinking water installation can be better adapted to the circumstances 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, housed inside the 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 cabinet that is accessible through the sink cabinet. 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. Particularly 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 make the drinking water installation otherwise confusing and prone 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 Wasserentkalkungseinrichtungen. The achievable advantage of a further connection for unfiltered water is that the time interval between replacement of the water filter or a filter cartridge is extended, whereby time and costs 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 It is particularly easy to close and re-open the device water outlet, which can be an advantage when servicing a device or changing a connection, since not all the water supply has to be closed and the use of blind plugs can be dispensed with.

In a preferred WVV, at least one water inlet or outlet has a 3/8 inch pipe thread. Here is the achievable advantage that commercially available water-conducting household appliances without the use of adapters can be connected, since most commercial water-conducting household appliances have water connections with screw threads of 3/8 inch nominal diameter. For the use of equipment having ports of other sizes, an alternative embodiment of the WVV also has 1/2 inch and / or 1 inch nominal water outlets. This makes the WVV even more versatile. 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.

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 line connections, more preferably three utility water lines. For example, a drain of a sink, a utility water drain of a dishwasher and / or a washing machine and a drip water drainage of a hot water boiler can be connected to the multiple siphon. The achievable advantage of the integration of the multiple siphon in the WVV is that a particularly 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 comprises a drain which is arranged pivotable by 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.

Preferably, all water inlets and water outlets of the WVV are provided with labeling means. Labeling advantageously allows each water inlet and outlet to be identified. This simplifies the identification of the individual water connections.

Preferably, the maximum width of the WVV is less than 55 cm. This has the advantage that the WVV fits in a standard sink unit with a typical width of 60 cm. Particularly preferably, the width of the WVV is less than 45 cm. This has the advantage that the water connections are even easier to access.
