  • a control device which monitors the underlying treatment process and controls.
  • US 3,692,180 describes another device for treating or reprocessing water in a compact design, which provides a small container for drinking water, in which the water is treated by passing ozone bubbles through the water over a certain period of time.
  • This water purifier also has devices that prevent ozone from entering the atmosphere. In order to effectively prevent the formation of excess ozone gas, the ozone generator is automatically switched off after predetermined time intervals.
  • the known devices for treating or reprocessing water have the disadvantage that, on the one hand, they do not have the sufficient flexibility to meet the requirements of a treatment device for water purification and water disinfection. In particular, time coordination of the different purification units or subunits is difficult or even impossible at all. On the other hand, these systems do not make it possible to make changes to the purification units in a simple and cost-effective manner, for example in order to adapt individual system units to changed initial conditions in the water to be treated. Although maintenance work can be carried out on these devices for treating or reprocessing water, special measures to simplify these activities cannot be seen from this.
  • a treatment unit for the treatment or purification of water is finally known, in which several filters are formed side by side in the device housing.
  • This processing unit is replaced by changing the processing materials in the processing units, such as activated carbon, iodine-containing resin, filters etc.
  • the processing unit is formed by individual cartridges or cartridges attached to the device, the fillers of which can be replaced or which can be replaced individually.
  • the present invention is based on the object of providing a generic treatment device for water and for this purpose a household appliance which avoids the disadvantages mentioned above and by which it is possible to control the course of various purification processes independently of one another in terms of time. Depending on the nature of the quality of the water to be cleaned, it should also be possible to use different treatment units with different cleaning processes.

  • All of these purification units can be formed in a single preparation unit and can be connected to a suitable household appliance via input or output lines.
  • the individual purification units can be controlled independently of one another and do not, as described in the prior art, have to be controlled as separate cartridges formed at different points in the household appliance.
  • Such a processing unit can be easily removed and disposed of as a whole from the household appliance and can be easily replaced by a new one.
  • purification units are arranged one behind the other in the flow direction in the individual material paths, that is to say, for example, the suspended matter filter, the ion exchanger and the activated carbon filter can form a material path for the water, while an air dryer in series with an ozone generator and a second material path Ozone destroyer, which frees ozone-containing exhaust air from the surface of the mixing chamber when the ozone is dissolved in the water, forms a third material path.
  • the processing unit thus forms a central station in the household appliance, in which all purification processes, such as chemical oxidation, adsorption, filtration and dispensing of substances, such as adding flavor-changing substances, are carried out. Such a central station is easy to handle, can be quickly replaced and checked if necessary.
  • the separation of the processing unit from the household appliance enables simple replacement or replacement together with the integrated cleaning units.
  • the processing unit can be combined with other cleaning units Replace the equipped treatment unit if it is necessary to adapt it to the changed starting conditions of the water to be treated. This can be the case, for example, by moving or changing the water quality by changing the source of supply.
  • the change of the processing unit from the household appliance can on the other hand also lead to a simplified implementation of any maintenance work that may be required on the household appliance.
  • processing unit is not understood to the extent that in the individual purification units of the processing unit only “filter processes” (in the literal sense) for the processing of the substance can take place, but that such purification processes can also take place at which, for example, chemical reactions take place.
  • filter processes in the literal sense
  • the water to be treated is fed to the individual purification processes and, after the entire treatment has been completed, can be led out of the treatment unit again via a single drain.
  • the line couplings are designed so that they can be easily separated from the corresponding pipe connections in the household appliance or connected again without significant water or ozone escaping.
  • the processing unit is always completely replaced when it is exhausted.
  • at least one material path for filtration and purification of the water to be treated and at least one material path for preparation of the air / ozone mixture to be prepared can be provided.

  • at least one material path for air enriched with ozone and at least one material path for the water are required (claim 5).
  • the material paths provided according to the invention in the treatment unit can thus be used in a variety of ways for the processes taking place during the treatment, in particular not only for the water to be treated itself, but also for those substances which are useful for the entire treatment process, or which arise unintentionally and therefore must be destroyed again

  • the connections are arranged in an approximately horizontal plane in the upper region of the processing unit.
  • the processing unit is disassembled from the household appliance, it can be ensured that no noteworthy liquids emerge from the openings of the feed and discharge lines, since any residual liquids that are present migrate to the lower region of the processing unit due to the effect of gravity.

  • the free space 100 between the device box 97 and the processing unit 40 serves as an outlet of the pipe sockets 84 to 88 and can also serve as a space into which both the cleaned air flows in from the line 75 and the air for the ozone generator 48 is extracted.
  • the fifth purification unit 45 and the second purification unit 42 can also be located in separate water circuits parallel to the first purification unit 43, so that these - in addition to the connection lines 74 already described, 69, 20, 70, 73 - have their own connection lines (not shown) and can be controlled via valves (not shown) in such a way that the first, fifth and second purification units 43, 45, 42 are either in succession, side by side or in time as required can only be switched on when the water has flowed through one of the purification units 43, 45, 47 practically completely purified and is only then fed to the next purification unit 45 or 42.
  • the simplest solution is shown in that all three purification units 43, 45, 42 are connected directly one after the other in the fluid circuit, so that this results in only a second water circuit, which is only switched on after the water in the first water circuit is only was enriched with ozone.
  • the construction of the treatment unit 40 shown in FIGS. 2 to 7 with different material paths 53, 54, 55, 56 makes it possible to carry out the water purification in individual steps side by side or also at a distance one after the other.
  • the disinfection can be carried out in a multi-stage continuous process for a quantity of water to be removed from the household appliance. The duration of exposure to the disinfectant essentially depends on the volume flow of the sample and the volume ratio in the household appliance.
  • disinfection for a larger preselected amount of water can be carried out in a cycle process. The water is circulated in a reaction vessel and subjected to the various process stages.
  • FIG. 1 The mode of operation of FIG. 1 in conjunction with the water treatment system for an electrically operated household appliance shown in FIGS. 2 to 7 is as follows:
  • the household appliance is switched on by means of the main switch (not shown) before the lid 13 can be removed from the vessel 2.
  • an electrical locking device (not shown) formed between the lid 13 and the vessel 2 can be used, which only allows the lid 13 to be opened when there is no longer any ozone in the form of a gas cushion 27 in the chamber 25.
  • an ozone sensor (not shown) is formed in the plug 13, which always measures the ozone content in the gas cushion 27 and feeds this to the electronic control device 82, which then releases the electrical locking device or not.
  • an additional air pump (not shown) designed in the device must first generate air in order to supply gas in the chamber 25 via line 20 to the fourth purification unit designed as ozone filter 46 and to remove the ozone there. So-. as soon as the gas cushion 27 is free of ozone, the plug 13 can be removed from the vessel 2.
  • the same can apply correspondingly to the processing unit 40, because it should only be possible to remove it from the housing box 67 when the device is not in operation or when no more ozone is measured in the lines 18, 73.
  • This electronic check can also be measured via additional sensors (not shown) and transmitted to the control device 82, which in turn then does not issue the command to separate the processing unit 40 from the device box, which can be done via mechanical / electrical actuators (not shown).
  • water 22 can be entered into the vessel 2, which consists either of a water pipe or of rainwater or other contaminated water.
  • the plug 13 is closed again, but the jet mixer 21 with the pipe 16 and the pipe 19 of the exhaust pipe 20 remain in the plug 13.
  • the supply and discharge lines 17, 18, 20 are flexible in the area of the plug 13.
  • the household device can a possibly second switch or also be switched on automatically and the first process step can begin.
  • the pump 12 is switched on automatically by hand or via the control device 82, the valve 31 is opened and the valves 32, 72 are closed. However, this only if a control device has determined that the processing unit 40 is securely seated in the household appliance. Furthermore, the ozone generator 48 switches on and water now circulates via the connecting line 11 to the pump 12, from there via the output line 28 to the bypass line 29 back to line 17 and back into the jet mixer. 21. Since the flow of water in the jet mixer 21 is so large, gas is sucked in via the line 18, corresponding to the mode of operation of a water jet pump, so that air according to FIGS. 1 to 7 is first of all passed through the line connection 68 into the third purification unit trained air dryer 44, where it is dried and finally flows via line 74 into the ozone generator 48 and is enriched there with ozone.
  • This ozone-containing air reaches the jet mixer 21 according to FIGS. 1 to 7 and is mixed there with the water and emerges as a water jet 23 from the jet mixer 21 and impinges on the water surface 26 of the water 22 in the vessel 2 the water jet 23 mixed so violently with the water 22 that the ozone-air bubbles 24 even more be refined and there is a better dissolution of the ozone in the water.
  • This water 22 enriched with ozone is in turn fed via line 11 to the pump 12 and runs again via the outlet line 28, the bypass line 29 and the line 17 back into the jet mixer 21.
  • the valve 31 closes according to FIG. 1 and the valves 32, 72 are opened, so that the water enriched with ozone reaches the first purification unit 43 (FIGS. 2 to 7) via the treatment line 30 and the valve 33, in which the enlarged turbidity clumps or gloom are filtered out or removed from the water by settling.
  • the ozone generator 48 is switched off.
  • the water which has now been partially cleared of the cloudy matter, flows via the outlet line 38 into a fifth purification unit 45, in which the lime is removed from the water.
  • This fifth purification unit 45 can also be omitted if the water offered in a country is not particularly calcareous, or it can alternatively only be switched on by a further bypass line and a valve if this is desired by an operator or if this is specifically required by an operator Device used monitoring device (not shown) is switched on automatically.
  • the water After the water has been decalcified in the fifth purification unit 45, it flows according to FIGS. 1 to 7 via the line 39 into the second purification unit 42, where it is freed of ozone.
  • the water containing less ozone in this way flows via the line 73, the valve 72 and the line 17 back into the jet mixer 21, where the water is only mixed with air, since the ozone generator 48 has been switched off and thus the Air 68 sucked in air is only dried in air dryer 44 and then flows through the ozone generator without enrichment of ozone and then reaches the jet mixer 21 as dried air via line 18.
  • This second process step also runs in a cycle until the ozone sensor 35 no longer detects ozone in the water. This is a measure of the fact that the water is sufficiently cleaned and de-ozone.
  • the line 70 to a sixth purification unit 47 can also be opened by opening the three-way valve 33, in which flavors or other minerals or additives are added to the water and / or unpleasant odors are removed from it.
  • This second bypass line 83 leads via the output line 83 to the three-way valve 72, where it then flows back to the jet mixer 21 via line 17.
  • the two three-way valves 33, 72 can be switched so that both water flows through the first and second purification units 43, 42 and water through the sixth purification unit 47.
  • the material feed device 47 can also be controlled by the three-way valves 33, 72 such that only the water flows through the lines 70, 83 - and then no longer through the two first and second purification units 43 and 42.

  • the plug 13 can now be removed from the vessel 2 and the purified water 22 can be removed from the vessel 2. It is possible for the vessel 2 to be lifted from a housing base 7 carrying the vessel 2, although a pipe socket 102 must then be formed at the outlet 6 of the vessel 2, in which the check valve 8 which closes when the vessel 2 is lifted from the appliance base 7 is trained.
  • the vessel 2 can be gripped by the hand of an operator via the constriction 4 and the water 22 can be removed from the vessel 2 via the filling opening 3. Afterwards, unpurified water can be poured into the vessel 2 again, the lid 13 inserted into the injection device 21, the vessel 2 placed in the receiving opening 10 of the housing bowl 7 and the device can be fed to a next cleaning process.
