Definitions
- the invention relates to a sparkling water device according to the preamble of claim 1.
- Sparkling water devices, water carbonators, carbonation devices or soda water devices for enriching tap water with carbon dioxide or CO2 have been in use for many years as an alternative to mineral water or table water with carbon dioxide in filled containers, so-called bottled water.
- piped water filter systems have been established in front of the tap or at the water tap, or so-called water filter jugs, e.g. from the company Brita in Taunusstein (DE), with which a predetermined amount of water can be filtered gravimetrically via a two-chamber system (upper chamber for impure water, lower chamber for pure water).
- DE Brita in Taunusstein
- the invention therefore has the task of providing a simplified
- the object is achieved, starting from a sparkling water device of the type mentioned at the outset, by the characterizing features of claim 1, for a filter of claim 17, for a mineralization stage of claim 22 and for a manufacturing method of claim 23.
- the invention proposes the integration of a water treatment stage into a sparkling water device in order to ensure water conditioning by filtration or by adjusting the mineral content in order to prepare sparkling water of consumer-friendly quality.
- the invention also enables a combination of a water filter system and a simple sparkling water device without a feed pump, without electrical connection and without hydraulic and/or pneumatic connection to a mains water network, and therefore also avoids the disadvantages of a separate water filter and sparkling water device.
- the invention is characterized in that the flow through the water treatment stage in the sparkling water device is controlled by using the applied pressure can be realized from a pressure cylinder filled with C02 gas used in the sparkling water device.
- the water can be forced through a filter and/or through a mineralization stage to enrich the water with minerals and treated, which enables rapid water treatment without the need for the additional integration of an electrically driven feed pump, without connecting the device to a mains water network and without the previously described disadvantages of alternative combinations with externally operated water treatment systems.
- the filtration or mineralization of the water can take place at the end of the CO2 carbonation of the water, in another embodiment also before the CO2 carbonation of the water, but filtration or mineralization between the beginning and the end of the CO2 gas carbonation of the water would also be conceivable in order to obtain optimal sparkling water quality.
- the water can be driven through a filter via a hydraulic and/or pneumatic pump driven by CC>2 gas.
- the water could be driven by CO2 gas through the water filter and/or through the mineralization stage, and in the process, a special gas pressure reservoir could be charged with CO2 gas, which would then release its pressure again during the carbonation process of the water.
- the filter also serves as a CO2-gas distributor (gas distribution frit), through which the gas is introduced into the water in small bubbles via a porous filter body. When the sparkling water is drawn off, the sparkling water flows through the filter in the opposite direction by reversing the pressure conditions.
- the filter and/or the mineralization stage is integrated into a carbonator (pressure vessel in which the CO2 gas enrichment of the water takes place) integrated into the sparkling water device, from which the filtered sparkling water can be drawn off from the device in different portions.
- a carbonator pressure vessel in which the CO2 gas enrichment of the water takes place
- the filter used in the sparkling water device serves to reduce the chlorine from the tap water and/or the reduction of heavy metals and/or organic contaminants, such as chlorination by-products, pesticides, medical residues, hormones, particles and/or the reduction of water hardness and/or microorganisms and/or fine plastics.
- the filter consists of a compressed filter granulate and/or a sinter-like solidified or solidified by means of binding agents at low temperatures and shaped granulate of ion exchange resin and/or activated carbon granulate (also called carbon filter block in the professional jargon of the filter industry) or other combined Filter materials or mineralization materials or mineralization granules.
- the filter has a stable three-dimensional structure with a fine pore structure, for example in the form of a filter block, through which the CO2 gas can be introduced into the water, in particular for better absorption of the CO2 gas in the water can be introduced in fine bubbles and when the flow is reversed, the water enriched with CO2 gas can be filtered through the filter in the opposite direction to that in which the CO2 gas was introduced.
- a fine pore structure for example in the form of a filter block
- a mineralization stage specifically designed for remineralization for example in the form of a mineralization cartridge or mineralization cartridge, can be integrated into the sparkling water device in order to enrich water with a low mineral content to a desired mineral content, for example when the tap water comes from seawater desalination, or when the water used has previously been desalinated by a reverse osmosis system.

- Sparkling water device with pre- and final carbonation and gas-driven pump which is driven by CO2 gas from the gas cylinder and presses pre-carbonated water through the filtration and/or mineralization stage into the final carbonator, from which a portioned withdrawal takes place
- Fig . 7 a schematic representation of a
- the water reservoirs 12 and 22 have a triple functionality:
- This sparkling water device 30 also initially features a gas cartridge 31 and a water reservoir 32.
- the water reservoir 32 serves here for pre-carbonation and for further transport of the water under pressure during carbonation.
- pre-carbonation is used because a vessel 34 is provided at the end for final carbonation.
- the path of the water up to this point is basically analogous to the devices 10, 20 according to Figures 1, 2. That is, the water is pressed from the pre-carbonator 32 through the line LW via the valve V through the filter 33 (and/or a mineralization stage) into the pressure vessel 34.
- a filter 53 is arranged in the reservoir 52 here.
- a mineralization stage for mineralizing the water or a device comprising the filter and the mineralization stage can also be used.
- the filter and/or mineralization stage is/are arranged here in the reservoir tank 52 and is/are located in the water.
- the filter and the mineralization stage is/are designed such that it/they has/have an inlet and an outlet that opens directly into the line LW.
- Figure 5 thus represents an embodiment which, for example, shows a water tank as reservoir 52, which can be equipped with a filter cartridge or a filter candle.
- the filter cartridge or candle is arranged in the tank and is permanently immersed in water. It has an inlet and an outlet and can be flowed through.
- the arrangement of the filter or the mineralization stage would therefore be similar to that in a fully automatic coffee machine, although in fully automatic coffee machines the water is usually sucked out of the tank by an electric pump, which is not necessary here.
- a pump 66 is used for the first time. However, it is not an electrically operated pump, but a gas-driven pump. Again, the line LG from the gas cartridge 61 splits into two parallel lines. Lines LG1 and LG2 are connected, with line LG2 leading into a pressure vessel 64 for carbonation, or rather, for final carbonation. Line LG1 now leads to pump 66 and drives it with gas.
- the gas that drives pump 66 can still be used: It flows out via line LG3 and is fed into reservoir 62 to carry out pre-carbonation there and, at the same time, to force the water, which is incompressible and cannot escape, through line LW due to the increase in pressure. Above all, however, the water is sucked from reservoir 52 into line LW by pump 66.
- the simultaneous effect of the suction of the pump and the pressure of the CO2 gas introduced into reservoir 62 results in a particularly effective and/or complete transport of the water volume from reservoir 62.
- the pump 66 pumps the water further through the filter 63 and/or the mineralization stage into the vessel 64, into which the line LG2 flows for final carbonation.
- FIG 7 A particularly preferred development of the invention is shown in Figure 7, which primarily represents a very compact design and shows a simple pipe layout that also requires few valves.
- the line LG (which can be shut off by a tap) leads directly into the water reservoir 72, which also serves as a carbonator.
- the gas line is directly connected to a so-called gas distribution frit or filter frit 73, which consists of a porous structured Filter material is formed and enables a fine distribution of the gas in the water.
- the sparkling water can be drawn off directly from the water reservoir 72.
- the CO2 pressure in the water reservoir 72 forces the sparkling water in the opposite direction through the filter 73 and into the line LW.
- a mineralization function for sparkling water can also be integrated into the filter, or a mineralization stage can be used instead of the filter.
- the filter and/or mineralization stage 73 has/have a dual function. First, they serve as a gas distribution frit during the carbonation of the water in the water reservoir 72, and after carbonation is complete and the sparkling water is drawn off, they serve as a filter or mineralization stage for the sparkling water.
- the frit 73 can comprise a granular material as a filter or mineralization stage that forms or has a pore structure and can be used to filter the sparkling water.
- the gas connection or line LG and the water line LW can be connected directly to the gas distribution frit or filter frit 73.
- a line LG3 leads from the pump 86, through which the gas for driving the pump 86 can be transferred to a pressure accumulator 87 and stored.
- the CO2 gas stored in the pressure accumulator 87 can pressurize the vessel 84 via the line LG3 and be used for pre-carbonization.
- the final carbonation in the vessel 84 also takes place via the gas line LG2 (with a lockable valve VH), through which the vessel 84 or the carbonator can be directly pressurized with CO2 gas.
- the carbonator 84 can be emptied via a tap VH ( e . g . into a drinking glass 85 ) .
- the pressure accumulator 87 is a gas accumulator for the temporary storage or stockpiling of gas. It is conceivable that the pressure accumulator 87 is designed as a diaphragm vessel that expands via an elastic diaphragm when filled with gas and contracts again when emptied (e.g., by opening a valve in its outlet) by contracting the diaphragm.
- valves shown in Figures 1-8 are only examples. Other valves may be used if necessary. It is also conceivable that individual valves are not necessary and can be omitted. All embodiments and further developments of the invention have in common that carbonated sparkling water can be produced without significant delay, but is filtered and/or mineralized and of high quality with defined properties. However, the sparkling water device of the invention is simplified and environmentally friendly because the pumping process for transporting the water is accomplished by the gas pressure that is used for carbonation anyway.
