Abstract

The invention relates to a supplementary second faucet spout for standard tap valves, single-hand mixer faucets, or two-hand mixer faucets, for dispensing hot or cold tap water or other suitable liquids and which can be adapted for dispensing soda-water other liquids.

Description

The invention relates to an adapter for dispensing valves (mixers one-handed or two-hand lever) to provide them with a second tap spout to remove soda water or soft drinks over the additional second tap spout.

It is known that soda water and soft drinks can be taken from a tap.

From the DE 196 08 482 A1 a mixing valve with a first outlet mouth and a base with a second separate outlet mouth is known, wherein the separate outlet mouth is connectable to a separate water supply. The adapter known from this document has the features of the preamble of claim 1.

From the FR 2 755 361 a mixing valve with a first tap outlet and an adapter with a second tap outlet is known, wherein the second tap outlet is connectable to a liquid container.

The DE 198 02 200 A1 discloses a dispensing device for liquid container with a connection pipe and an outlet pipe, wherein in the connection pipe a compensator is fixed by means of holding elements.

The invention is therefore the object of developing an adapter such that the flow rate of soda water regulatable and at the same time different soda water qualities can be removed.

This object is solved by the features of claim 1.

The novel to the invention is that z. B. a normal kitchen faucet by the novel second tap spout so that makes it possible at the point where the conventional tap is placed (in most cases in the sink area) then in this place by the cultivation of the second tap spout is possible below the conventional tap spout to take soda water or soft drinks through the additional second tap spout.

This removal of soda water by the novel second tap spout has no connection with the conventional tap spout, except that the two tap spouts are supplied by the same cold water supply with cold water.

The conventional tap (mixer tap) (pictured not shown) is interrupted by the water supply cold and hot water (unscrewed), possibly also from the supply line for dishwashers and washing machines.

The new second faucet spout sits on the place above the recess where previously the old dispensing valve (mixing valve) was built up as the first of the new additional tap spout (pictured).

The additional faucet spout is designed so that there is enough space for the supply line for the new faucet spout and for the old faucet as well as for the faucets for the old tapping point, which is to be understood as an empty tube with integrated faucet spout.

The aforementioned empty tube can also be constructed so that this sleeve, which may be made of metal or other materials an integrated bracket for a faucet outlet shows that you can remove said tap spout from this and so used as a holder for the tap spout.

So that the additional second faucet spout fits tightly and securely in place, this second faucet spout has its own mounting option or is brought to a secure hold by the existing mounting options of the old tap (mixer tap).

The new second faucet outlet, which is responsible for the removal of soda and soft drinks, is placed over the old Ausspahrung for the conventional tap (mixer) what is already in the existing countertop or in the sink and on it comes the old nozzle.

By using the existing fasteners you can also use new fasteners that are matched to the old fitting and the novel second tap spout.

Such a mounting gives the novel faucet outlet a secure attachment.

The supply lines for the old tap valve (mixer tap) are replaced by adapter lines or also by new lines if they are now too short by mounting the second tap spout (not pictured).

For nozzles that have a pivoting faucet outlet is the rigid connection between the fitting and the new second tap outlet, which is responsible for the removal of soda and soft drinks, and the worktop (sink) characterized in that the old nozzle further independent of the second tap spout the pivot function the old faucet outlet can be used (not pictorially shown).

The novel second tap spout has a special feature that the tap spout is used for soda and soft drinks or even for filtered or purified tap water has an integrated compensator.

This compensator then has the function to take over the closing and opening options for the user.

The compensator in the faucet outlet before the outlet for soda, purified tap or soft drinks by a mechanical operation, which sits on the faucet outlet to operate the Kompensatorenzylinders which may also be conical to use said cylinder to open or close the liquid flow.

According to the invention, the possibility of the compensator (conical cylinder or non-conical cylinder should be safe from food materials, eg VA steel) mechanically (other types of movement are conceivable) in the directions with the liquid flow to the tap outlet or against the liquid flow to move.
By such a possibility of use of the compensator, it is now possible to regulate the flow rate of the flounces (soda water).

The advantage is that the user of the novel second tap spout (or as a single stand-alone spout) by different adjustment options of the compensator (cylinder with matching cylinder guide) has the opportunity to take different types of soda via the tap spout.

Another design of the novel second faucet spout (generally referring to the faucet spout) is that the faucet spout with integrated compensator and closing and opening operation as well as regulating the liquid flow rate may consist of two parts, of retainer and removable faucet spout with integrated movable spout Compensator in the area in front of the faucet outlet.

Another object of the movable removable faucet spout from the holder which comes through the old draufgelegt tap valve (mixing valve) is used, that the novel faucet outlet is provided with a flexible conduit which makes it possible to take the faucet spout from its holder, whereby the user of the novel Faucet outlet is able soda water or soft drinks and filtered or purified tap water outside the sink area to refill his drinks in containers (bottles, glasses) (not shown pictorially).

Another variant is that the aforementioned construction options and applications of the additional second tap spout is already integrated by design in a tap with at least one cold water inlet, so as a complete unit but with different functions namely only cold water and soda water and soft drinks or filtered and purified tap water ( not shown pictorially) or as a single-hand mixer in conjunction with the second tap spout for soda and Erfrischungsgetrlnke but also as a two-hand mixer also with the second tap spout, of course, have installed a built-in faucet compensator or cylinder mechanically or permanently.

Another variant is that in the region of the second tap spout a mechanical control element is present to produce the Co ² -Stom in the direction of system soda water or soft drinks and thus this system offers the opportunity to take the desired drinks on the novel tap spout, the possibility one also for the required Flümigkeiten (tap water) into consideration.

Another variant is the required tap water needs (liquids) to produce in conjunction with Co ² soda water and soft drinks is the required amount of liquid (tap water) by activity, for example, in a single-lever mixer tap release for the tap water required to produce soda water, this is then about the one-hand lever control unit which is also responsible for cold and hot water and mixed water to construct so that at a new position which otherwise is not present by the newly created position, it may be the Wasserbarf (liquids) for the supply for the system it allows soda water in particular and also via a static mixer produce (pictorially not shown).

In order to enable and close the tap water flow through a single-lever mixer tap that provides power for the production of soda water (or filtered and cleaned tap water), it must be used in case control or other release and closure systems by newly developed systems.
This also applies to two-hand lever mixing valves (not pictorially shown).

The installation possibility to allow the compensator (cylinder) in the new second tap outlet (single tap spout) is solved as follows. The faucet spout to be used with a compensator is manufactured in such a way that this faucet spout can be divided into two parts which can be screw-jointed in connection with flexible sealing material which is also gas-tight.
The lower part of the faucet spout towards the faucet spout is designed to allow the inner cylinder guide to be conveniently conical to the cylinder within the tap spout for a conical cylinder. The preferred spout outlet materials must be food grade materials (not shown).

It makes it necessary to remove it via the new faucet spout with integrated compensator, and this is solved in such a way that it is possible to screw a supply line (which can also be squeezable) to the faucet spout.
This supply line can also be flexible.

With the tap spout with integrated compensator that you can attach from its holder to the nozzle (mixer tap, mixer tap) to fill with soda water or soft drinks, it is possible between the tap outlet and mixing system (static mixer) to attach a weight to the supply that the user of the tap spout after completing the tapping process makes this faucet spout more convenient.

In order to integrate a Venturie in the mixing system, which is necessary in order to adjust over the novel faucet spout with integrated compensator and is mechanically so is loosened that the Venturie is constructed so that a connection for a supply line for the Co ² supply for the mixing system necessary to make soda water (not pictured).

When using a static mixer, it is solved so that the supply line leading to the tap outlet is connected by a screw or crimp connection with the static mixer in the tap outlet direction.
As a next step, the static mixer (or other mixing systems to produce soda water) will need to use a venturi, which will also be attached to the mixing system (static mixer) in the direction of the tap spout by screw or crimp connections (not shown pictorially).

Even with the use of a Venturie (must not necessarily be in a given case) in this case, the Flfiissigkeitsversorgung for the mixing system via a T-piece where the required Co ² supply a connection option is available, is solved so. The possibly the Venturie at the main cold water supply which is also for the cold water supply of the normal dispensing valve (mixing valve) via a new double shut-off valve on the side that is necessary for the supply of tap water for soda water production with a check valve or similar systems are conceivable. The closed soda water system guarantees that no Co ² gas can get into the main water line or into the normal annature. Therefore, the non-return system must also be gas-tight, this check system must also be used on the gas side (not pictured).

Co ^{2 is} necessary for the production of soda water. This is solved so that at the mixing system for the production of soda water with the new faucet outlet is connected for a consistently good soda water quality is a constant Co ² pressure and a constant Co ² flow rate necessary.
This requires a Co ² pressure reducer with flow rate regulation.

The required Co ² pressure reducer can also be used as Überdruckbegmnzer.
This is solved so that the required Co ² pressure reducer has a built-in pressure relief valve.This pressure relief valve may optionally be adjustable to various overpressure functions. At this mentioned Co ² pressure reducer, a holder can be integrated, which serves the purpose of the pressure reducer by screwing on the flush sub table or on the masonry comes to a secure stop (not shown pictorially).

For the supply of the pressure reducer with Co ² , which is required to produce soda water, a Co ² container is needed.This is solved so that the pressure reducer port for Co ^{2 shows} 90 degrees down and has a screw. There are also other conceivable closure options to apply.

Co ² containers without riser must be removed in an upright position. This is solved so that it is possible the Co ² container by the matching connection possibility of the Co ² container is tuned to the connection possibility of the Co ² pressure reducer.

Due to the 90 degree bend downwards, an upright removal of Co ² from the Co ² container can be guaranteed. Since the Co ² pressure reducer can be screwed on, there is also a safe position for the Co ² container (not pictured).

The Co ² containers (cartridges) are refillable. This is solved so that the exchange Co ² container (cylinder) by a mail order principle every user of the novel faucet spout makes it possible soda water or soft drinks to tap allows a replacement cylinder with Co ² to get easily (not shown pictorially).

In case the mixing system to produce soda water is made by a static mixer, so this can be designed so that it also serves as a tap water filter or cleaner. By a way to open the static mixer, it may also be cleaned or provided with new filters become (pictorially not represented).

In order to remove any filter system before the system to soda to spigot and the new tap spout this is so dissolved that a filter system upstream of the tap water (liquids in the mixing system) upstream this can also for the nonnal cold water supply for the normal mixing valve (dispensing valve ) are used (pictorially not shown).

A solution was found that way. If the operator of the novel faucet spout with integrated compensator cooled drinks (soda water or filtered tap water) is desired, then a cooling (preferably a continuous cooling device with integrated timer for on and off of the cooling device) in front of said mixing system to soda water or even tap water Cones such as filtered, purified tap water (liquids) (not pictured).

If other systems for the novel second tap spout are used, which make it possible to produce soda, this is solved so that then the novel second tap spout on the system that it is able to produce soda water is capable of the novel faucet spout soda or soft drinks to tap. Consideration could be given to systems such as the well-known processes such as Primex or Posmix and the process used in the beverage industry to produce CO ² via the created vacuum and to produce the selenium (soda water) in combination with mineral water.

There is a solution for a good and high CO ² enrichment in the tap water when a static mixer is used which is constructed as follows: as a special feature of this static mixer is that it consists of individual sieves so that the meshes of the individual sieves arranged on each other are. The preferred shape of the sieves are round, but can also have a different shape. For example, oval depending on the need for the enrichment of CO ² in liquids (tap water), different sieve strengths and mesh sizes or drill holes can be used. It could also be used if necessary between each sieve required for the Siebmischer is necessary Spacers are intregiert or each sieve has structurally from the screen material already a manufactured Abstanzwulz then replaced the spacers. If it is necessary to use spacings between the individual sieves, this can also be achieved by gumming the individual sieve elements as a spacer distemper to the subsequent sieves inside the mixing tube. The screen material must be made of food grade materials. For example: VA steel as well as the sheath in which the sieves sit. The number of sieves for a static mixer and the diameter of the individual sieves as well as the sieve strength and also the mesh size, must be adapted to the respective field of application. A static mixer constructed as described above can also be applied to other fields of application. For example: in wastewater treatment, beverage industry, agriculture or horticulture in Treibhäusem for the liquid supply of plants, vegetables or fruits. The static mixer as previously described can also be used for irrigation of sick trees. It is intended for a general industrial application of the above-described static mixer, which also applies to motor vehicles in the application of catalyzers. Depending on the construction, this static mixer described above can be used in conjunction with sieve elements for all types of gas which are also to be mixed with one another or in connection with liquids. As well as for dispensing systems that can produce soft drinks or for beer brewing or wine industry to produce soft drinks. But also in general in the food industry (not pictured).

The task is that the CO ² pressure reducer is needed a CO ² removal from the CO ² container which can be refilled after Entleerrung for the required CO ² pressure is adjustable and its special connection option for the CO ² container protection is unauthorized To prohibit persons and companies refilling with CO ² . This also applies particularly to the cylinder valve of the CO ² container which is considered for use.

A further embodiment of the invention is that there is an adapter option when the mixing fitting one-handed or two-hand mixing valve (dispensing valve) does not fit together in diameter this adapter can be used.

Further details of the invention will become apparent from the following detailed description and the accompanying drawings in which preferred embodiments of the invention are illustrated, for example.
