Definitions

  • the present invention relates to a method and a device for providing at least enriched with CO 2 drinking water and non-enriched with CO 2 drinking water, in which the unreacted drinking water and / or the enriched drinking water is removed if necessary by means of one or more suitable dispensing valves. Furthermore, the invention enters a device which operates according to the said method.
  • EP 1892214 A A device according to the introductory part of claim 6 is known from EP 1892214 A known.
  • Such devices are usually referred to as a water dispenser. They are known in various embodiments.
  • water dispensers are considered in which an operator can tap at least two or more different types of drinking water.
  • other types of drinks can be obtained from such water dispensers, such as so-called soft drinks.
  • Water dispensers either have a local drinking water reservoir and / or are connected by means of a suitable connection to a drinking water pipe which is present in a building, for example. Regardless of the type of drinking water source used, the water in such water dispensers is susceptible to nucleation. This is often caused by longer stagnation times of the respective drinking water in the piping system of the water dispenser.
  • un-enriched drinking water - hereinafter referred to as "un-enriched" drinking water - by means of a conduit system of the device, starting from a water source along a CO 2 -Ariching device in which the unreacted drinking water is enriched with CO 2 , to a dispensing valve led for the enriched drinking water, in particular pumped, over which the enriched drinking water is finally removed.
  • a (usually further) dispensing valve is arranged in the line system, via which the unreacted drinking water of the device can be removed.
  • the discharge valve for the unreacted drinking water, the CO 2 enrichment device and the discharge valve for the enriched drinking water are arranged in the manner of a series connection and fluidly connected to each other. Based on the flow direction of the outgoing from the drinking water source drinking water therefore the output valve for the unreacted drinking water, the CO 2 enrichment facility and the output valve for the enriched drinking water are arranged in this sequence successively.
  • the connection of the facilities or organs is usually created by means of suitable, water-bearing components, such as pipes, hoses, or other fluid conduits or fluid channels, such as valves or the like.
  • the decisive factor in relation to the flow direction of the drinking water is the arrangement of the dispensing valve for the unreacted drinking water, the CO 2 enrichment device and the dispensing valve for the enriched drinking water within the line system in a row indirectly - namely optionally with the interposition of other components - or immediately one after the other.
  • the drinking water starting from the drinking water source, first flows to the dispensing valve, via which a user can tap unreacted drinking water as required. Downstream of this dispensing valve, the unreacted drinking water is then converted to enriched drinking water and finally to the appropriate dispensing valve for enriched drinking water.
  • all of the lines which the inflowing drinking water flows from the drinking water source to the delivery valve for the enriched drinking water are flowed through by fresh water originating from the drinking water source.
  • the through-flow lines are advantageously cleaned by the inflowing water and the water in the lines is replaced by fresh water.
  • the invention is based on the recognition that CO 2 -enriched drinking water is generally much more in demand from users than drinking water enriched with CO 2 or not enriched with CO 2 .
  • those lines are also cleaned by inflowing drinking water or the drinking water is also exchanged in those lines which are arranged upstream of the discharge valve for the unreacted drinking water.
  • the lines leading to the CO 2 drinking water dispensing valve on the one hand are connected in parallel to the unavailable water dispensing valve and are connected to a Y-connector only in the region of the dispensing, for example.
  • a tapping of drinking water enriched with CO 2 exclusively leads to the afterflow of drinking water in the corresponding CO 2 drinking water pipes.
  • the water in the unreacted drinking water pipes, on the other hand, does not flow or is not replaced by the removal of enriched drinking water.
  • the dispensing valve for the unreacted drinking water, the CO 2 enrichment device and the dispensing valve for the enriched drinking water are usually only indirectly connected to one another. It can be interposed fluid-conducting in the line system various other liquid-conducting components or devices
  • a cooling device is also connected in series and, downstream of the cooling device, a further dispensing valve which serves to dispense then cooled, unreacted drinking water.
  • the device would be able to dispense at least three different types of water, namely uncooled, unreacted drinking water, cooled, unreacted drinking water and (cooled) enriched drinking water.
  • the unreacted drinking water is preferably passed through a passage of the valve for unreacted drinking water.
  • This valve passage is preferably formed by a valve inlet and a first, in particular permanently liquid-conducting connected to the input output of the valve.
  • the unreacted drinking water is supplied via suitable supply lines or line sections of the line system to the valve inlet and out of said first output out of the valve.
  • the first output then connects the valve to the other lines of the piping system, which forward the drinking water, in particular in the direction of the CO 2 enrichment device or in the direction of the discharge valve for the enriched water.
  • the discharge valve for the unreacted drinking water next to the first output via which the water of the series circuit is further led to a second connected to the input or connectable output, the opening of which is closable with a closing member.
  • This second exit is the actual extraction outlet, via which the unreacted drinking water can be removed at the delivery point of the device.
  • the individual dispensing valves preferably form a contiguous dispensing area or dispensing block, in which the individual dispensing valves are arranged. Preferably then open the closable or openable outputs of the valves to a common outlet channel through which the selected drinking water in the direction of a container, such as a cup, can flow.
  • the dispensing valves are preferably part of a valve device which has at least two valves, wherein the first valve has an input and at least two outputs connected or connectable to the input, wherein one of the outputs has a movable closing member with which the output can be closed and at Demand is releasable.
  • the dispensing valves can be controlled by means of a suitable control, so that, for example, after the selection of a particular type of drinking water by a user, the dispensing valve corresponding to the selected type of drinking water is opened.
  • Fig. 1 shows the schematic diagram of a device 10 for providing at least enriched with CO 2 drinking water and non-enriched with CO 2 drinking water, namely a water dispenser.
  • the device 10 has a housing, not shown, as well as a conduit system 20.
  • the line system 20 in this case comprises an output unit 12, at the three different types of water or water types are removed, namely not enriched with CO 2 , uncooled drinking water (also called Ambientewasser), cooled, unreacted drinking water (also called still water) and cooled, with CO 2 enriched drinking water.
  • uncooled drinking water also called Ambientewasser
  • unreacted drinking water also called still water

  • the output of this second cooling device 32 is connected via the line 20e to the input of a CO 2 enrichment device 34, namely with a so-called Karbonatorlan.
  • the drinking water which is pre-cooled by the first cooling device 30 and the second cooling device 32, enriched with CO 2 .
  • the output of the enrichment device 34 is connected to the line 20 f to an input 36 of the third output valve 18.
  • the valves 14, 16 are each designed such that the respective valve inlet and the respective, first valve outlet 28 are permanently connected to one another in fluid-conducting manner. In other words, the drinking water entering the valve 14, 16 flows through the interior of the valve housing 26 and exits at the respective valve outlet 28.
  • the two valves 14, 16 each have second valve outputs 38. These open into a common outlet channel 40.
  • an outlet 42 of the third dispensing valve 18 opens into the outlet channel 40.
