Definitions

  • the invention relates to a device for producing carbonated water, according to the preamble of claim 1.
  • the sparkling water can also be produced at home in corresponding sparkling water devices.
  • water coming from the tap is mixed with carbon dioxide in the device. In this way, table water is obtained without great technical effort.
  • the previously known devices for producing carbon dioxide-added table water for domestic use have the disadvantage that the mixing device for supplying the carbon dioxide into the water is very voluminous because a storage container for the water is provided, over which a carbon dioxide atmosphere in excess pressure is provided the goal is that the carbon dioxide gradually dissolves in the water.
  • the efficiency of introducing the carbon dioxide into the water is also not optimal.
  • the invention is based on the objective of creating a device for producing carbonated water with an improved mixing device.
  • the basic idea of the mixing device lies in a microstructure, which can be formed, for example - and in particular - by plastic or by a ceramic.
  • This micro structure has a large number of small outlet openings on the one hand for the water and on the other hand for the carbon dioxide. Since these outlet openings lie close together and thus a large surface area and short diffusion paths are formed, the outflowing carbon dioxide immediately comes into solution through the close contact with the water, so that the carbon dioxide is introduced directly into the water in the micromixer.
  • the outlet openings preferably have a diameter of less than 1 mm, particularly preferably a diameter of less than 200 ⁇ m.
  • An advantage of the device according to the invention is that the large number of outlet openings each have the same diameter. As a result, the concentration of carbon dioxide in the table water can be adjusted by the choice of the diameter of the outlet openings.
  • This micro structure as a mixing device has the advantage on the one hand that it is small and on the other hand the advantage that the efficiency is very high and the residence time water / carbon dioxide is very short. As a result, the table water is poured out immediately after the two components have been mixed without a calming phase. Precisely adjustable concentrations of carbon dioxide in water are achieved through precisely defined dimensions of the microstructures of the mixing device.
  • micromixers made from poorly heat-conducting materials, such as plastic is that the temperature control is more effective and faster than that of macroscopic mixers, by combining and / or integrating the micromixers and heating and / or cooling elements.
  • the development according to claim 2 has the advantage that the greatest possible contact between the two media water and carbon dioxide is created. Basically, it is also conceivable that the outlet openings are formed in a matrix-like manner, the matrix points of the carbon dioxide outlet openings lying between the matrix points of the water outlet openings.
  • the development according to claim 3 proposes designs of the outlet openings in the form of nozzles, the cross-sectional shape being essentially point-shaped.
  • a further development according to claim 5 proposes a preferred embodiment of the microstructure.
  • the basic idea lies in a lamella-like micromixer system, the comb-like structures forming guide channels for the water and for the carbon dioxide.
  • these microstructures it is possible in a technically simple manner to bring the two media to be mixed together, namely the water and the carbon dioxide, into contact with one another.
  • these comb-like structures can be form elements, with a flat counterplate on the lamellar, comb-like structures delimiting the flow channels.
  • the water supply is preceded by disinfection in order to make the microstructure and the dispensing mechanism sterile.
  • the development according to claim 8 proposes that the mixing device is preceded by cooling.
  • the basic idea of the development according to claim 9 is that the cooling device is directly assigned to the mixing device in such a way that at the same time as the carbon dioxide is being fed into the water (and the carbon dioxide) and thus the table water is cooled.
  • the advantage is that by integrating the cooling device into the mixing device, elements of the mixing device can also be used for the cooling device. Overall, the cooling of the table water is improved.
  • Another advantage is that in the event that the device according to the invention consists at least partially or entirely of plastic, the table water can be dispensed without additional cooling phases, since the mixing device has a small mass and this enables a correspondingly rapid temperature change or regulation.
  • a preferred embodiment of the cooling device in the form of a Peltier element is proposed by the development according to claim 10.
  • the cold side of the Peltier element is used for cooling.
  • the Peltier element can preferably be plate-shaped.
  • the use of a Peltier element as a cooling device represents a simple possibility for the technical implementation of the cooling device.
  • the further development according to claim 12 proposes an alternative to this with the use of a heating device for disinfection.
  • a preferred further development proposes claim 13, the basic idea being to combine the cooling device, in particular in the form of the Peltier element, with the microstructure for feeding the carbon dioxide into the water.
  • Both the microstructure for the carbon dioxide supply on the one hand and the Peltier cooling on the other hand are integrated in a common system in such a way that the microstructure is in operative connection with the Peltier element.
  • microstructure not only serves to supply the carbon dioxide into the water, but that this microstructure can also serve to remove the heat by means of a continuously flowing water stream, the heat being dissipated via micromechanical structures he follows.
  • the basic idea of the development according to claim 17 is to use conventional water fittings from the basic principle and from the arrangement, but which are additionally equipped with a mixing device for supplying the carbon dioxide into the water.
  • This enables a direct production of table water using the micromixing process.
  • the particular advantage of the mixing device within the water fitting is that the water mixed with the carbon dioxide is emitted immediately and thus no water mixed with carbon dioxide "stands" in the line.
  • the mixing device can be integrated as a type of cartridge in the tap. By appropriately designing the mixing device, it has only a small dimension, so that the water fitting modified in this way does not differ in size from conventional water fittings.
  • the mixing device can be a micromixer with an integrated cylindrical shape. The switchover and connection of carbon dioxide to the water can be implemented technically using simple controls.
  • the development according to claim 18 has the advantage that "still water” or “medium” can be tapped when the carbon dioxide supply is switched off or throttled. According to the development in claim 19, the variant is also possible in which water is directed past the mixing device. This corresponds to the function of a "normal" faucet.
  • a further development with the additional supply of syrup proposes claim 20.
  • the basic idea lies in the production of mixed drinks, i.e. A syrup concentrate is added to the pure table water in the tap or immediately after the tap, so that the drink gets a certain flavor. Additional lines can be integrated in the water fitting for the syrup admixture. The connection of syrup or similar additives can be technically implemented using simple controls.
  • a mixed syrup feed enables the addition of different flavors.
  • the development according to claim 21 has the advantage that the compensator directly at the opening of the tap prevents premature decarbonization of the table water and gently reduces the overpressure when the table water is tapped in the sense that the carbon dioxide does not escape excessively.
  • Figure 1 is a purely schematic view in the manner of a block diagram of the manufacturing device with Peltier cooling.
  • FIG. 3 shows a kind of a fragmentary exploded view of the illustration in FIG. 2 in a first variant
  • FIG. 4 shows a kind of a fragmentary exploded view of the illustration in FIG. 2 in a second variant; 5 and 6 show more detailed representations of the embodiment in FIG. 3;
  • FIGS. 7 and 8 show more detailed illustrations of the embodiment in FIG. 4;
  • the device for producing table water mixed with carbon dioxide of the purely schematic representations in FIGS. 1 and 2 has a mixing device 1 with a water supply 2 and a carbon dioxide supply 3.
  • a heating device / disinfection device 4 is connected into the water supply 2.
  • the mixing device 1 has a cooling device 5 in the form of a Peltier element. This is connected to a voltage supply device 6 (which also controls the heating device 4 at the same time).
  • the Peltier element of the cooling device 5 is sandwiched between two plate elements 7, the left plate element 7 in FIG. 2 being connected to the water supply 2 and to the carbon dioxide supply 3, while the right plate element 7 is connected to cooling lines 8.
  • a microstructure 9 is assigned to the mixing device 1. In the embodiment of FIGS. 3 and 5 and 6, this microstructure 9 is arranged on both sides of the Peltier element of the cooling device 5, while in the embodiment of FIGS. 4 and 7 and 8 the microstructure 9 is arranged on the plate elements 7 is.
  • the microstructure 9 of the mixing device 1 cannot be seen. It is arranged on the opposite bottom of the illustration. Can be seen in Fig. 1, i.e. on the visible upper side of the illustration, however, is another microstructure which is arranged in FIG. 2 between the Peltier element and the right plate element 7. This microstructure is thus connected to the cooling lines 8 and, due to its large surface area, serves to improve the cooling of the warm side of the Peltier element of the cooling device 5.
  • the microstructures 9 are formed with two comb structures, the fingers 10 of the two comb structures interlocking in opposite directions.
  • One comb structure is connected to the water supply 2 and the other comb structure to the carbon dioxide supply 3.
  • the plate element 7 has a slot-like passage opening 11. Since the plate elements 7 on the Peltier element of the cooling device 5, the corresponding through openings 11, in cooperation with the comb-like channel structures, form outlet openings 12 with an essentially rectangular cross-sectional profile. Outlet openings 12 alternate with one another for the water and on the other hand for the carbon dioxide.
  • the functioning of the mixing device 1 is as follows:
  • the water is fed to the mixing device 1 by means of a pump 13.
  • carbon dioxide is fed to the mixing device 1 from a storage container 14.
  • the mixing device 1 Through the comb-like microstructure 9, the water and the carbon dioxide are guided in the comb-like channels until these media exit through the outlet openings 12. After this exit, the water comes into contact with the carbon dioxide so that they mix with one another in such a way that the carbon dioxide dissolves in the water.
  • the bottled water thus produced is discharged via line 15. Since the mixing structures are located in the region of the cold side of the Peltier element of the cooling device 5, the bottled water is cooled at the same time. The Peltier element is cooled on the warm side by means of the cooling lines 8.
  • FIG. 9 shows an exemplary application of the mixing device 1 with the microstructure 9 in a water fitting 16, as is usually present in a water basin 17.
