Definitions

  • the present invention relates to a water tap with a mixer tap for use in a connection system for use as a high-pressure or low-pressure fitting and a corresponding connection system for use as a high-pressure or low-pressure fitting.
  • An insert for use in a connection system according to the invention, the use of an insert in a connection system according to the invention and a method for producing a water tap according to the invention are also disclosed.
  • Water taps are known from everyday life, with a water tap usually being part of a connection system, which can also include hoses and other components, for example.
  • Conventional faucets have a so-called mixing faucet, which is also known as a mixing fitting, for dosing the water flow and setting the water temperature.
  • the temperature desired by the user is set in appropriate water taps by the mixing faucet by dosing and mixing cold and warm water.
  • High-pressure fittings are usually used when the fitting is directly connected to hot water networks, instantaneous water heaters or pressure boilers where the hot water is under full mains pressure. These fittings are because of that characterized in that they only have two connections, a cold water connection and a hot water connection. The cold and hot water streams are mixed inside the mixer tap by a so-called mixer cartridge and discharged via a common outlet.
  • low-pressure fittings which are suitable for use with an unpressurized boiler, have three connection lines.
  • the faucet has a cold water outlet, through which the cold water is routed from the faucet to the boiler, and a hot water inlet, through which the water heated by the boiler is routed through the faucet to the outlet.
  • the basic principle of a faucet with a mixer tap is known in the prior art.
  • Corresponding mixer taps are, for example, in DE10057591C1 , the DE 102005061032 A1 or the DE19507195A1 disclosed.
  • DE 4421387 A1 discloses a single-hole faucet for mixing and/or dispensing cold, warm or mixed water.
  • the EP 2388378 A2 discloses a water pipe fitting with a cartridge having a variable-length control disc and three openings for water flow for supplying and distributing cold water, hot water and mixed water.
  • the EP 0060481 A1 discloses a valve for a sanitary water mixing faucet having a fixed ceramic valve seat disc with three ports and a sliding ceramic valve disc.
  • the DE 1072443 B discloses a mixer tap with a single handle that can be used to adjust not only the mixing ratio of two liquids but also the total discharge amount.
  • the DE 20 2019 105 673 U1 of the inventor of the present invention discloses a faucet with a mixer tap which can be used as a high-pressure or low-pressure faucet.
  • the mixing cartridges mentioned above which actually mix the water flows inside the mixer tap, are established components that were developed back in the 1940s.
  • mixing cartridges there are two flat ground ceramic discs that can be moved and rotated against each other.
  • the fixed, underlying ceramic plate in the Mixing cartridge has three openings.
  • a rotatable and pivotable second ceramic plate in which a single recess is worked.
  • the mixing cartridge's control lever By operating the mixing cartridge's control lever, the position of the hole in the movable ceramic plate relative to the stationary ceramic plate is changed, thereby creating a connection between the underlying openings, through which the streams of water can flow.
  • Corresponding mixing cartridges which are also referred to as mixing units or control cylinders, are for example in DE 102004035644 B4 and the DE 112017000317 T5 as well as the US5853023 and the US5375624 disclosed.
  • the tap previously used in the kitchen may no longer be compatible with the connection in the new property.
  • the resale value of used faucets the look of which is usually tailored to a specific kitchen or bathroom facility, is regularly low, whereas the acquisition costs of a new faucet, which in turn matches the desired design, can be considerable.
  • the problems described above not only result in high costs, but also in considerable effort. Waste is also generated by the faucet that is no longer required, which the specialist would like to avoid, especially in times of dwindling resources and greater environmental awareness among consumers.
  • the present invention is therefore based on the primary object of eliminating or at least reducing the disadvantages of the prior art described above. Accordingly, the present invention is based in particular on the object of specifying a faucet that can be used equally in a connection system as a high-pressure and low-pressure fitting, and thereby solves the problems described above.
  • the task was to specify a faucet and an associated connection system whose structure is so simple that even a layperson can switch it from low-pressure operation to high-pressure operation by making small structural changes.
  • the water tap to be specified should not form any closed reservoirs in which stagnant water can collect.
  • the objective was that the water tap to be specified should be easy and cost-effective to manufacture, namely using only such equipment and process steps that are already used in the production of conventional water taps.
  • the main body of a faucet is regularly referred to as the battery body.
  • This battery body and its configurations are fundamentally familiar to a person skilled in the art.
  • the battery body includes elements for mounting the faucet on a sink, for example with a thread.
  • the water outlet of the faucet is arranged on the battery body, which can extend, for example, as a straight or curved faucet from the battery body.
  • the battery body and the outlet can, in principle, be made of any conventional methods known to those skilled in the art material that is in principle suitable for the production of water taps can be produced, metals and metal alloys, in particular iron, steel and aluminum, being particularly suitable.
  • the battery body has a receiving space, the walls and floor of which are formed by the battery body, and which is provided for receiving a mixing cartridge.
  • Mixing cartridges with an adjusting lever are described in the prior art and conventional mixing cartridges are used within the scope of the present invention.
  • Conventional mixing cartridges have a first, a second and a third opening on the end face facing away from the adjusting lever, it being possible to establish a connection between the various openings by aligning the adjusting lever.
  • the adjusting lever of corresponding mixing cartridges is intended to be connected, for example, to a one-hand handle and thus enable the consumer to adjust the water temperature and the volume flow by moving the two ceramic discs arranged in the mixing cartridge against each other.
  • the mixing cartridge is designed in such a way that it is also regularly used in the prior art, namely in such a way that by aligning the adjusting lever a connection between the first and the second opening, between the first and the third opening and between the first and the second and the third opening, i.e. all three openings simultaneously.
  • Corresponding mixing cartridges are regularly designed in such a way that it is not possible to establish a connection exclusively between the second and the third opening.
  • the connection of the openings is achieved by the mutual displacement of the two ceramic plates in the mixing cartridge and is due to the superimposition of the holes in the ceramic plates.
  • the bottom of the receiving space includes a first, a second, and a third hole. These holes extend as channels through the part of the battery body lying under the floor of the receiving space and emerge on the outside of the battery body facing away from the receiving space.
  • the first hole and the first channel form an associated first connection
  • the second hole and the second channel form an associated second connection
  • the third hole and the third channel form an associated third connection.
  • the connections are intended to be connected to water pipes. Even if the first, second and third connection are formed by a hole in the simplest case, it is therefore preferred that the first, second and third connection have means for fastening water pipes, for example screw threads.
  • the channel connected to the first hole i.e. the first channel, which is also connected to the first connection, also comprises a first outlet, via which the first channel is additionally connected to the water outlet.
  • This outlet is usually inside the battery body between the first hole and the first terminal and extends through the battery body toward the water outlet.
  • the faucet defined above in the generic term is a faucet with a mixer tap, which can be used as a low-pressure fitting and which accordingly has three connections.
  • the faucet can also include other components, in particular clamping screws for fixing the mixing cartridge in the receiving space or cover caps.
  • the third channel which is connected to the third hole, is also additionally connected to the water outlet via a second outlet, with both the first outlet and the second outlet being in the respective channels, ie in the first and third channel, respectively.
  • a suitable insert also referred to as an adapter, so that liquid can flow between the connection, ie the first or third connection, and the hole, ie the first or third hole, without exiting through the respective outlet.
  • the faucet according to the invention is therefore only conditionally suitable for direct operation without the insert, but is suitable for use in a connection system according to the invention which at least also includes the insert.
  • Either the first or the second outlet in the corresponding channel of the water tap according to the invention can be bridged by the insert. This allows the connectivity in the tap and thus its functionality to be controlled and specifically changed by the arrangement of the insert. If the second outlet in the third channel is bypassed by the liner, a faucet will be included that will match the original connectivity and functionality of a low pressure faucet as defined in the preamble, as the second outlet does not affect the fluid flow in the port system. If the first outlet in the first channel is bridged by the insert, then a faucet is included in which the position of the only open outlet has been changed relative to the position of the mixing cartridge in the low pressure faucet, i.e. without actually changing the position of the mixing cartridge or other components, namely from the first channel to the third channel.
  • a corresponding connection system with use in the first channel of the faucet according to the invention is suitable for use as a high-pressure fitting, with the third outlet being appropriately closed with a plug.
  • connection system which includes the faucet according to the invention
  • the flow of the water streams in the various operating variants and the production of the faucet according to the invention are disclosed below.
  • the faucet according to the invention solves the problems described above and makes it possible to use the faucet in both high-pressure and low-pressure operation, ie as a high-pressure and low-pressure fitting, depending on the position of the insert in the connection system.
  • the connection system according to the invention with the water tap according to the invention is suitable for use as a low-pressure fitting.
  • the third connection is connected to a cold water supply, the second connection to the cold water inlet of a low-pressure heater, e.g. an unpressurized boiler, and the first connection to the hot water outlet of the low-pressure heater. If necessary, cold water enters the first hole via the mixing cartridge via the third hole in the battery body, from where it reaches the water outlet via the first channel and the first outlet arranged in it.
  • Low-pressure heaters which are also referred to as open or non-pressurized hot water tanks, are known to those skilled in the art.
  • all common low-pressure heaters can be used within the scope of the present invention. If hot water is requested by actuating the control lever, cold water flows from the third hole via the mixing cartridge into the second hole, from where it is fed to the low-pressure heater. The hot water provided by the low-pressure heater returns from the low-pressure heater via the first connection into the first channel and via the first outlet arranged in the first channel to the water outlet.
  • the water tap or the connection system is suitable for operation as a high-pressure fitting if the insert is arranged in the first channel and the third connection is closed, for example with a plug.
  • the term stopper encompasses all structures and elements that are suitable for sealing the third connection in a liquid-tight manner, at least in the direction of the line, with a closure being particularly preferred that can be removed without leaving any residue. Sealing elements with a screw thread are particularly preferred.
  • the cold water supply is connected to the first connection and the hot water supply to the second connection. In this arrangement, when cold water is requested, it enters the mixing cartridge through the first hole and from there into the third hole.
  • the liquid only reaches the water outlet from the third channel via the second outlet arranged in the third channel, since the third connection is closed by the plug. If the control lever is moved to the hot water position, hot water through the second hole into the mixing cartridge and from there into the third hole, through which the hot water reaches the water outlet again through the second outlet.
  • the constant flushing of the third channel, which is closed with the plug, with the hot and cold water from the first and second channel prevents stagnant water from accumulating, which could be disadvantageous from a health perspective. Even after longer phases of non-operation, a consistently high water quality can be ensured by a relatively short flow of the water tap.
  • Water taps according to the invention are preferred, with the first and/or second and/or third connection, preferably all connections, being provided with screw threads.
  • first and/or second and/or third connection is preferred because it enables the water hoses or water lines to be attached securely and quickly and can regularly be connected particularly easily to the existing infrastructure.
  • both the first, the second and the third connection are provided with screw threads.
  • Water taps according to the invention are preferred, with the first and/or the second outlet extending over more than half the circumference, preferably over the entire circumference, of the corresponding channel and in particular being designed as an interruption of the respective channel.
  • Corresponding faucets are particularly advantageous since they allow a large flow of liquid through the corresponding outlets.
  • the channels are designed as tubes that are at least partially exposed in the battery body, corresponding outlets can also be produced particularly efficiently and easily, for example using a hacksaw.
  • connection system according to the invention can be used as a high-pressure or low-pressure fitting depending on the positioning of the insert.
  • the connection system according to the invention also solves the above-mentioned tasks.
  • connection system according to the invention can be quickly and cost-effectively redesigned with only minor modifications, which in case of doubt can also be carried out by a layperson, so that it can be used both as a high-pressure fitting and as a low-pressure fitting.
  • Our own tests have also shown that the connection system according to the invention is particularly safe and can also be installed safely by inexperienced consumers, since even an improper connection of the water tap, i.e. a connection of the fitting set to high pressure or low pressure to the other system, does not lead to all the usual problems with conventional water taps, but only manifests itself in an unfavorable mixing of the warm and hot water flows, which leads to a reduction in the achievable hot water temperature.
  • the consumer in this case can easily change the position of the insert and allow for proper operation.
  • connection system is only required if the connection system is to be set for high-pressure operation, in which case the third connection must be sealed with the plug.
  • hoses have also proven to be a particularly expedient way of connecting a connection system according to the invention, since they are significantly easier to handle than, for example, rigid copper pipes.
  • connection system is preferred, wherein the insert is a rigid or flexible, preferably a rigid, hollow body, preferably a pipe or hose, and or the insert having attachment means for attaching the insert to the battery body.
  • the insert is suitable and intended for bridging the first or second outlet arranged in the first or third channel, so that liquid can flow between the connection and the hole in each case without escaping through the outlet.
  • the insert is expediently a hollow body that can carry the liquid from the connection to the hole inside.
  • the shape of the insert essentially corresponds to the inner contours of the first and third channels, respectively, and has essentially the same length. If the channels are, for example, tubes with an inside diameter A and a length B, the use is preferably a tube or hose with a maximum outside diameter A and a maximum length B.
  • the insert preferably has fastening means for fastening the insert in the battery body, as a result of which particularly secure installation and a good fitting position of the insert are ensured.
  • fastening means for fastening the insert in the battery body, as a result of which particularly secure installation and a good fitting position of the insert are ensured.

  • a connection system according to the invention is preferred, in which the insert comprises at least one sealing element which, when the insert is inserted into the battery body, creates a liquid-tight connection between the insert and the wall of the respective channel, so that no water can get past the insert through the first or third hole can flow through the respective channel.
  • the insert comprises at least one sealing element which creates a liquid-tight connection between the insert and the wall of the respective channel when the insert is inserted into the battery body.
  • this sealing member is located at the tip, i.e. the outermost quarter, of the insert which is positioned closest to the first and third holes respectively.
  • the sealing element is preferably one or more, preferably two, sealing rings.
  • sealing elements also contribute to a better hold of the insert in the channel due to increased friction on the channel wall.
  • a further seal (secondary sealing element) to the inner wall of the channel on the side of the insert facing away from the tip is possible, in particular for further stabilization, but is often superfluous since the secure connection to the hose is of greater importance on this side.
  • a connection system according to the invention is preferred, in which the insert is connected to a hose or can be connected to a hose via a connecting piece, which enables a liquid-tight connection between the insert and the hose.
