Description

Technical area

The invention relates to a cleaner supply and dosing device with at least one dissolution and storage container, a structure for positioning at least one treatment agent in the form of a solid, at least one circulation pump and at least one filling water supply line. The invention further relates to a method for providing at least one fluid-soluble solid treatment agent for commercial ovens, steam cookers and dishwashers for cleaning, descaling and rinsing, as well as to the use of the method for treating devices to be cleaned.

State of the art

Multiple dosing systems for dosing cleaning products are traditionally represented by the use of liquid cleaners. Here, a defined portion of a cleaner is conveyed to the place of use using a dosing pump from a canister that stores the cleaner. These systems are inexpensive due to the components used, but cause relatively high transport costs due to the high water content. Furthermore, the canisters represent a high proportion of the weight of plastic waste generated. An advantage of such liquid dosing systems is the simple dosing and their relatively long storage stability due to the defined conditions in production.

In EP 2 502 542 B1 a multiple dosing system is described, which completely dissolves a treatment agent provided in a cartridge in powder, tab, block or gel format with a predetermined amount (for example filling quantity 1 l) in a defined amount of fluid, preferably water, through a one-time dissolution process and the resulting liquid treatment agents stored in a storage container.

Such systems do not require interference-prone measuring technology to determine a cleaner concentration. However, due to the provision of a large amount of solid cleaner and the fact that it is sometimes stored in a storage container for a long time, precipitation can occur within the storage container, which can lead to blockages in the filters and dosing pumps of a dosing system, and in the worst case, to sludge. The cause of the precipitation is often undefined local water quality when the solid cleaner dissolves.

Other multiple dosing systems described below dissolve a solid cleaner in individual portions, which are then fed directly or promptly to the point of use. This avoids long downtimes and thus prevents precipitation.

EP 2 905 069 A1 refers to a dosing device for providing at least one cleaner or at least one cleaning component and to a method for operating a dosing device. This includes a storage chamber and a circulating medium circulated in it by means of a circulation pump. The circulation pump conveys the circulating medium in the circuit. The circulating medium is applied to the at least one cleaner or the at least one cleaner component via nozzles in a time-defined manner. The defined cleaner, descaler and rinse aid solution created here is then used for cleaning, descaling and rinsing items to be washed, the muffle area of an oven or steamer, a milk pipe system or a coffee brewing unit in fully automatic coffee machines. The treatment agent produced here is subject to strong concentration fluctuations. One embodiment variant is intended to enable an almost constant amount of dissolved cleaner by spraying for a long time until a saturation range is reached.

WO 92/04857 A1 discloses a dosing device which, with the aid of a solvent, preferably water, produces a concentrated treatment solution from a solid cleaner stored in a cartridge through a time-limited wetting or spraying. The cleaner is only partially dissolved. Design measures should ensure a more closely defined concentration range and avoid clogging of pumps and filters. However, the concentration ranges vary within a fairly wide range between 9% and 16%. However, controlled monitoring using electronic sensors to set a previously defined concentration range does not take place.

DE 10 2020 100 554 A1 discloses a system for cleaning a device that carries drinking water, consisting of a filter candle that can be inserted into a filter head, and a cleaning cartridge that can be exchanged for the filter candle. The cleaning cartridge includes an adapter into which a cleaning agent, preferably a tablet, can be inserted. To clean the water-carrying device, the filter candle used for water treatment on the filter head is replaced by the cleaning cartridge, the adapter of which is loaded with cleaning agent. The tablet in the cleaning cartridge dissolves as the flow flows through it Water and is fed to the device that supplies drinking water via the outlet of the adapter.

The present invention is based on the object of providing a cleaning preparation and dosing device with which at least one treatment agent in solid form can be completely liquefied at the point of use and has the storage stability required for later applications.

In an advantageous development of the method proposed according to the invention, according to method step c), at least one treatment agent fluid mixture is produced in the at least dissolving and storage container by circulating a quantity of fluid by means of at least one circulation pump until the at least one treatment agent is partially or completely dissolved. This makes it possible to advantageously achieve that the at least one treatment agent is completely dissolved in solid form and the resulting residues are minimized.

In an advantageous development of the method proposed according to the invention, a first solid bar containing cleaner or a second solid bar containing descaler or a third solid bar containing rinse aid is used as a treatment agent in solid form. In a further development of the method proposed according to the invention, according to method step a), the water treatment unit contains active substances of the cation exchanger type, whereby cations that influence the hardness of water, calcium, magnesium, iron, aluminum or manganese, are removed from the supplied fluid. This allows the water quality to be significantly improved and, on the other hand, the storage time of a treatment fluid mixture can be significantly extended by such pretreatment of the water used.

Alternatively, when carrying out process step a), the water treatment unit can contain active substances of the anion exchanger type, whereby anions, in particular carbonate anions or poorly soluble sulfate anions, are removed, which significantly improves the quality of the water used to dissolve the treatment agent present as a solid.

In the method proposed according to the invention, the water treatment unit can also be used when carrying out method step a). lution contain active ingredients of the mixed bed ion exchanger type, whereby both cations and anions are removed and water is obtained with the quality of distilled water.

By using the method proposed according to the invention, at least one treatment agent is liquefied at the point of use in a cleaner supply and dosing device in such a way that a treatment agent fluid mixture obtained thereby has a storage stability which corresponds to that of a treatment agent produced under defined production conditions, filled and provided as a liquid container. A particular advantage here is that the outer packaging material and transport costs can be significantly reduced compared to liquid cleaning or treatment agents and, in addition, the service life of a treatment fluid mixture obtained can be significantly extended.

In the method proposed according to the invention, the unit for water treatment is advantageously designed to be regenerable in such a way that a water treatment agent or active substances for water treatment are periodically regenerated, which takes place via a regeneration unit which is filled with a regeneration agent and which provides a saturated solution of a regeneration fluid.

In the method proposed according to the invention, according to method step d) in the dosing cycle, liquefied treatment agent fluid mixture is fed in portions or continuously to the device to be cleaned in a defined concentration by means of a treatment agent metering pump.

In an advantageous development, the treatment agent according to process step d) can have active ingredients for water treatment of the zeolite type, whereby cations can be removed.

Advantageously, in the method proposed according to the invention, when inserting a block-shaped treatment agent with an integrated unit for water treatment or when inserting a container with active substances for water treatment into the loading drawer, these can be connected to a fluid inlet by means of a connecting coupling when the loading drawer is closed. This eliminates the need for connection work; The connection can be made, for example, simply by closing the loading drawer, so that a reliable coupling with the fluid inlet can be achieved and uniform wetting or dissolution of the treatment agent used can be achieved.

Finally, the invention relates to the use of the cleaning preparation and dosing device for treating and cleaning commercial ovens, commercial dishwashers, washing machines and coffee machines and the like. One use of the method proposed according to the invention for treating devices to be cleaned relies on solid cleaners and/or solid decalcifiers and/or solid rinse aids and/or cleaning enhancers or even bleaching agents and/or enzymes.

Advantages of the invention

The solution proposed according to the invention can save considerable packaging effort on the one hand and, on the other hand, considerable amounts of plastic material due to the use of essentially unpackaged treatment agents in the form of solids. It is now possible for a cleaner supply and dosing device to liquefy at least one treatment agent present as a solid at the point of use in such a way that the treatment agent fluid mixture produced has a storage stability that is comparable to that of a treatment agent produced under defined production conditions and present as a liquid container . The solution proposed according to the invention makes it possible in particular to avoid the occurrence of precipitation, which can then lead to blockages in filters and metering pumps during use. The solution proposed according to the invention ensures that a defined high water quality can be provided in the dissolving and storage containers of any design variant, so that the precipitation mentioned or, in extreme cases, sludging occurs and the treatment fluid mixtures are usable for a longer period of time and with the corresponding storage stability can be stocked. It is therefore possible to use a treatment agent fluid mixture that has already been prepared in the past after a number of operating cycles of a device to be cleaned in the form of a cooking appliance or an oven, a dishwasher or the like, without the adverse phenomena mentioned above occurring.

As a result of the solution proposed according to the invention, in addition to reducing the amount of packaging plastic that represents packaging waste, the transport costs can also be significantly reduced compared to liquid products in canister containers. By completely liquefying the at least one treatment agent present as a solid in a defined volume during a dissolution cycle, a proven and cost-effective dosing using liquid pumps can be used. The water treatment unit used in the cleaner supply and dosing device, which is connected upstream of it, ensures that fluid or filling water, which is used to dissolve the treatment agents present as solids, is produced under standardized manufacturing conditions of a production company. This ensures that high-quality water, which has previously undergone treatment, is used as the dissolving fluid and, regardless of the water quality at the site of liquefaction, a liquefied treatment agent is provided which has an almost unlimited storage stability before liquefaction and at least that long after liquefaction can be maintained like a conventional liquid treatment agent from its production date.

Furthermore, with regard to the solution proposed according to the invention, it should be emphasized that the shape/geometry of the different treatment agents in the form of a solid is designed to be complementary to the geometry of the respective closure inserts. This prevents accidental insertion of a treatment agent into an incorrect dissolution chamber.

Embodiments of the invention

In the following description of the embodiments of the invention, the same or similar elements are referred to with the same reference numerals, with a repeated description of these elements being omitted in individual cases. The figures represent the subject matter of the invention only schematically.

According to the perspective and partially sectioned representation 1 There is a cleaner supply and dosing device 10 in a double-chamber design for holding solid rods.

The cleaner supply and dosing device 10 in a double chamber design is used for single or multiple doses of treatment agents and includes in the embodiment variant according to 1 two adjacent dissolving and storage containers 40, 60 as well as first and second container overflows 43, 63 assigned to them and a water inlet 102 each.

There are two dissolution and storage containers 40, 60 provided as well as first and second closure inserts 46, 66 assigned to the two dissolution and storage containers 40, 60, which can be closed at a first closable opening 44 and a second closable opening 64. Treatment agents in solid form, for example a first solid rod 45 containing cleaner, or a second solid rod 65 containing descaler, or a third solid rod 68 containing rinse aid, can be inserted into the first or second closable opening 44, 64 be led. The solid rods 45, 65, 68 mentioned thus protrude into the respective dissolving and storage containers 40, 60 and are washed around by the fluid stored there and gradually dissolved, such that a first treatment agent fluid mixture 47 and a second treatment agent fluid mixture 67 is generated.

Ideally, the solid bodies, which are designed in particular as solid rods 45, 65, 68, can be designed differently in shape and color in order to avoid mixing up the products. As an example (see illustration according to 5 ), the first solid rod 45, containing cleaner, could be round, the second solid rod 65, containing descaler, could be triangular and the third solid rod 68, containing rinse aid, could be square.

In the in 1 In the illustrated embodiment variant of the cleaner supply and dosing device 10, for example, the first solid rod 45, containing cleaner, is introduced into the first dissolving and storage container 40 provided for this purpose by opening the first closable opening 44 and this is then closed in a liquid-tight manner. Thereafter, by opening the first solenoid valve 42, the first dissolving and storage container 40 is filled with a defined volume of an amount of fluid, preferably water, and after closing the first solenoid valve 42 and opening the second solenoid valve 49 and closing a third solenoid valve 50 the amount of fluid is circulated using a first circulation pump 48 until the first solid rod 45, containing cleaner, is completely dissolved. The first treatment agent fluid mixture 47 produced in this way corresponds in concentration and composition to the desired treatment agent fluid mixture, without the use of expensive, maintenance-intensive mechanical and/or electronic sensor technology. The first treatment agent fluid mixture 47 can then be cost-effectively and reliably via internal liquid metering devices, such as hose pumps, coffee machine pumps and the like, by means of the first circulation pump 48 by simultaneously opening the third solenoid valve 50 and closing the second solenoid valve 49, the first treatment agent fluid mixture 47 completely or partially in the area of application , for example a baking chamber, a water tank in the dishwasher and the like, can be dosed in portions or continuously.

In the same way, a second solid rod 65, containing descaler, and/or a third solid rod 68, containing rinse aid, can be introduced into the second dissolution and storage container 60 provided for this purpose by opening the second closable opening 64 and proceeded as outlined above.

From the illustration according to 1 It can be seen that the line system of the first dissolution and storage container 40 is assigned the solenoid valves 42, 49, 50 and the first circulation pump 48, whereas the second dissolution and storage container 60 is assigned solenoid valves 62, 69, 70 and a second circulation pump 52.

According to the representation 2 .1 is a side view of an embodiment variant of the cleaner supply and dosing device 10 with a loading platform with a regenerable unit 100 for water treatment. 2 .2 shows a section 2 .1 as a top view.

The cleaner supply and dosing device 10 according to 2 .1 and 2.2 includes the first dissolution and storage container 40 as well as a unit 100 for water treatment, furthermore a regeneration unit 101. The first dissolution and storage container 40 is with a structure in the form of a positioning platform 91 for positioning treatment agents in solid form, for example in Shape of the solid rods 45, 65, 68. The positioning platform 91 is located above a filling level 75 of a fluid, so that a treatment agent in solid form positioned on the positioning platform 91 in the form of one or more of the solid rods 45, 65, 68 does not come into contact with the fluid contained in the first dissolution and storage container 40 . In the top view according to 2 .2 it can be seen that the positioning platform 91 can be divided by a partition 93, whereby two treatment agents in solid form in the form of solid rods 45, 65, 68 can be accommodated here. These treatment agents, which are present as solid rods 45, 65, 68, can be placed on the positioning platform 91 of the first dissolution and storage container 40 by means of a closure cap 92. The option of stocking several treatment agents in the form of solid rods 45, 65, 68 at the same time increases the range until a new treatment with the treatment agents in the form of solid rods 45, 65, 68, without making the cleaning supply and dosing device 10 significantly larger in terms of its dimensions to have to.

In contrast to the version according to 1 Due to the integrated unit 100 for water treatment, a fluid, preferably water, can be optimally prepared before entering the first dissolution and storage container 40. This makes it possible to prevent flocculation and the resulting defects caused by blocked filters and metering pumps, especially when the residence time and storage time of the treatment agent present as a solid, in the form of solid rods 45, 65, 68, and liquefied first treatment agent fluid mixture 47, can be prevented.

For the optimal treatment of the inflowing fluid, preferably filling water, the water treatment unit 100 contains active substances 150. These can be cation exchangers, anion exchangers or mixed-bed ion exchangers. If the water treatment unit 100 is filled with active substances 150 of the cation exchanger type, the cations calcium and magnesium that cause water hardness as well as disruptive cations such as iron, aluminum or manganese are removed during the treatment of the filling water. If the water treatment unit 100 is filled with active substances 150 of the anion exchanger type, anions are removed during the optimization of the filling water, in particular carbonate anions or poorly soluble sulfate anions. Alternatively, if the water treatment unit 100 is filled with active substances 150 of the mixed-bed ion exchanger type, both cations and anions are removed when the filling water is optimized. A fluid, namely water, is obtained in the quality of distilled water. The unit 100 for water treatment is according to the exemplary embodiment 2 .1 designed to be regenerable. For this purpose, the active substances 150 for water treatment are regenerated after a defined amount of fluid (filling water) has been prepared. For this purpose, in addition to the unit 100 for water treatment, there is a regeneration unit 101 in the cleaner supply and dosing device 10. The regeneration unit 101 is filled with a regeneration agent 109, over which there is water, so that a saturated solution of regeneration agent 109 is formed. Depending on the type of active ingredients 150, a salt or an acid can be used as the regenerating agent 109 for water treatment.

After a request from a control unit 140, the treatment agent is positioned as a solid body in the form of solid rods 45, 65, 68 on the positioning platform 91 through the closure cap 92. This is confirmed by the operator at the control unit 140, whereby the control unit 140 puts the cleaner supply and dosing device 10 into a filling cycle. According to this filling cycle, the first dissolution and storage container 40 is filled with fluid, preferably water. For this purpose, the first solenoid valve 42 and a filling valve 108 of the dissolving and storage container 40 are opened by the control unit 140, whereas the solenoid valves, a filling valve 103 (regeneration), a regeneration valve 107 and a solenoid valve 105 for regrind outlet remain closed. Fluid, preferably water, now flows into the integrated unit 100 for water treatment via a filling water line 132, the inlet volume being defined, for example, by an opening time of a filling valve 42 for fluid inlet. In the illustrated embodiment according to 2 .1 this is done from an upper area of the water treatment unit 100. When the fluid, preferably water, enters the water treatment unit 100, the fluid comes into contact with the active substances 150. Here, the fluid, preferably water, which is of undefined quality, is optimally prepared by the active substances 150 for water treatment. Due to the open filling valve 108 for the first dissolution and storage container 40, the treated fluid can exit the water treatment unit 100 as filling water and flow into the first dissolution and storage container 40 via the filling line 120. When the filling level 75 is reached, the filling of the first dissolution and storage container 40 is completed. The control unit 140 now closes the first solenoid valve 42 and the filling valve 108 of the filling line 120 again.

Subsequently, the control unit 140 initiates the dissolution cycle, the dissolution of one of the two solid-state treatment agents in the form of solid rods 45, 65, 68 located on the positioning platform 91. For example, a seventh solenoid valve 80 is opened for this purpose, whereas an eighth solenoid valve 81 remains closed. The first circulation pump 48 sucks the fluid, preferably water, from the first dissolving and storage container 40 and sprays it via the solenoid valve 80 onto the treatment agent in solid form opposite the spray line 82 in the form of solid rods 45, 65, 68. These are completely dissolved, there is now a liquefied treatment fluid mixture 47 with a defined concentration within the first dissolution and storage container 40. The dissolution cycle is now complete. A further treatment agent as a solid rod 45, 65, 68, which also rests on the positioning platform 91 of the first dissolution and storage container 40, is protected and shielded from being sprayed by the fluid during this dissolution cycle by the closed eighth solenoid valve 81 and the partition 93.

After the dissolution cycle, the control unit 140 starts a dosing cycle, which is done by external signals. The first liquefied treatment agent fluid mixture 47 with a defined concentration is requested via the treatment agent metering pump 73 in portions or continuously to the device to be cleaned, for example a commercial oven, a commercial steamer, a steamer, a dishwasher, a commercial dishwasher, a commercial fully automatic coffee machine or the like.

As soon as a minimum filling level is reached in the first dissolution and storage container 40, the control unit 140 can initiate the start of a new filling cycle and, in a subsequent dissolution cycle, the previously undissolved further treatment agent opposite the eighth solenoid valve 81, designed as a solid rod 45, 65, 68 , dissolve and dose accordingly.

After a defined amount of fluid or filling water has been processed, the active substances 150 contained in the water treatment unit 100 are used up and must be regenerated. Within a regeneration cycle, with the first solenoid valve 42 closed and the filling valve 108 closed, the previously closed filling valve 103 with the regeneration unit 101 as well as the regeneration valve 107 and the solenoid valve 105 for the regenerated outlet are opened. Fluid now flows into the regeneration unit 101 as filling water and displaces the saturated salt and/or acid solution contained therein via a regeneration line 106 into the unit 100 for water treatment. There, the used active substances 150 contained therein are regenerated for water treatment by releasing ions absorbed by the active substances 150 during water treatment. Because the solenoid valve 105 for the regrind outlet is now open, the regrind leaves the cleaner supply and dosing device 10 via the outlet 104.

3 a cleaning supply and dosing device 10 in a single-chamber design with a loading drawer 90 and an integrated unit 100 for water treatment according to the disposable principle can be removed. The cleaning preparation and dosing device 10 includes the first dissolving and storage container 40, the first circulation pump 48, the treatment agent dosing pump 73 and a horizontally movable loading drawer 90. If several treatment agents should be designed in solid form for cleaning, in particular as solid rods 45, 65, 68, be desired within the first dissolution and storage container 40, the cleaner supply and dosing device 10 comprises two or more treatment drawers 90 as well as two or more opposing solenoid valves and spray lines 82, so that selective spraying of different treatment agents in solid form is made possible.

In the in 3 In the embodiment variant shown, the unit 100 for water treatment is designed to hold a container 160, filled with active substances 150 for water treatment, as a disposable unit. This means that the active ingredients 150 for water treatment are not intended for regeneration. This saves installation space and reduces manufacturing costs, and it is also ensured at all times that the cleaner supply and dosing device 10 is operated with correspondingly high-quality fill water.

The container 160 can accordingly 3 with a defined number of treatment agents, designed as solid rods 45,65,68, are sold in one sales unit. Here, the container 160 can be provided with active substances for water treatment with an RFID sensor or 310 or an RFID chip 311.

This in the unit 100 for water treatment according to the embodiment variant 3 Usable container 160 can contain active substances 150 for water treatment of the cation exchanger type, anion exchanger type and also of the mixed bed ion exchanger type or a zeolite.

An active substance 150 for water treatment of the mixed-bed ion exchanger type has the advantage over cation exchangers and anion exchangers that all types of disruptive components, whether anions or cations, can be exchanged. This creates the quality of distilled water. Active substances 150 for water treatment of the zeolite type work similarly to active substances 150 for water treatment of the cation exchange type, but are far more environmentally friendly.

In the in 3 In the illustrated embodiment variant of the cleaner supply and dosing device 10, the container 160 is first placed in the unit 100 for water treatment. The control unit 140 recognizes an RFID chip 310 located on the container 160 by means of an RFID sensor 311 integrated in the water treatment unit 100, and from now on cumulatively records what is in the water treatment unit 100 during each filling process via the filling valve 42 ( Fluid inlet) filling volume that has entered the cleaner supply and dosing device 10, preferably filling water. As soon as a cumulative volume of the filling water entering through the filling valve 42 at the fluid inlet has reached the total volume stored in the control unit 140 for dissolving the total number of treatment agents contained in a sales unit in the form of solid rods 45, 65, 68, the active ingredients 150 are available for water treatment The container 160 inserted into the water treatment unit 100 is consumed and the control unit 140 blocks the information used the RFID chip 310 for further water treatments. This ensures that the active substances 150 contained in the container 160 for water treatment are sufficient to optimally prepare the fluid, ie the filling water. This prevents flocculation and the resulting defects caused by blocked filters and pumps in a proactive manner.

At the request of the control unit 140, the first dissolving and storage container 40 is now loaded with the treatment agent in solid form in the form of solid rods 45, 65, 68. The respective solid rods, whether containing cleaner, descaler or rinse aid, are placed by the operator in the Open loading drawer 90 is inserted, after which it is closed. The closing of the loading drawer 90 is confirmed by the operator on the control unit 140, whereby the latter puts the cleaner supply and dosing device 10 into the filling cycle. The control unit 140 now opens the filling valve 42 at the fluid inlet. The inflow of the fluid, which is preferably filling water, takes place in accordance with the illustrated embodiment 3 via the fill water line 132 from a lower area into the water treatment unit 100. When the fluid, preferably water, enters the water treatment unit 100, the fluid, preferably water, also enters the container 160 and thereby also comes into contact with the active substances 150 for water treatment. Here, the fluid, preferably water, of undefined quality is optimally prepared by the active substances 150 for water treatment. The treated fluid (filling water) now exits the water treatment unit 100 and enters the first dissolution and storage container 40 via the filling line 120. When the filling level 75 of the fluid is reached, the filling of the first dissolution and storage container 40 is completed. The control unit 140 now closes the filling valve 42 at the fluid inlet again.

The control unit 140 now initiates the dissolution cycle, during which the dissolution of the treatment agent present as a solid in the form of solid rods 45, 65, 68 takes place. For this purpose, the first circulation pump 48 sucks in the fluid and sprays it over the treatment agents present as solid bodies in the form of solid rods 45, 65, 68. As soon as these are completely dissolved, a liquefied first treatment agent fluid mixture 47 lies in a defined concentration in the first dissolution and storage container 40 before. The dissolution cycle is now complete.

This is followed by the dosing cycle that is now to be started. This is also triggered by the control unit 140. First treatment agent fluid mixture 47 in liquid form in a defined concentration is supplied in portions or continuously to the respective device to be cleaned by means of the treatment agent metering pump 73. As soon as a minimum filling level is reached in the first dissolution and storage container 40, the operator is requested via the control unit 140 to use a further treatment agent in solid form, preferably in the form of a solid rod 45, 65, 68, which results in a new working cycle, comprising a filling cycle. a dissolution cycle and a dosing cycle can be completed.

As soon as all the treatment agents in solid form in the form of solid rods 45, 65, 68 contained in a sales unit are used up, the active ingredients 150 for water treatment contained in the container 160 of this sales unit are also used up. In contrast to the embodiment variant according to 2 .1 and 2.2, the water treatment agent 150 is not regenerated, but rather disposed of. By matching the capacity of the active substances 150 for water treatment in the container 160 of a sales unit with the total amount of water in the sales unit required to dissolve the treatment agents present as solids in the form of solid rods 45, 65, 68 in the same sales unit, optimal water treatment is guaranteed at all times. Since the control unit 140 has cumulatively recorded the total volumes of fluid (filling water) for dissolving all treatment agents contained in the sales unit and present as solid rods 45, 65, 68, it recognizes that the total capacity of the active ingredients 150 for water treatment within the container 160 has been reached and blocks it Information from the RFID chip 310 of the container 160 currently in the unit 100 for water treatment. The cleaner supply and dosing device 10 can now only continue to be used with a new container with the information of a new RFID chip 310, since the previously used unit 100 is exhausted in terms of its water treatment capacity and capability.

In 4 .1 shows an embodiment variant of the cleaner supply and dosing device 10 for using a multifunctional treatment agent 110 with an integrated unit 100 for water treatment according to the disposable principle.

According to this embodiment variant, the unit 100 for water treatment is part of the solid-state multifunctional treatment agent 110 in the form of solid rods 45, 65, 68 and is designed as a disposable unit, ie not regenerable. According to this embodiment variant, the cleaner supply and dosing device 10 does not require a device-integrated unit 100 for washing water treatment in the inlet area for the fluid, preferably filling water. Analogous to the exemplary embodiment according to 3 includes the cleaner supply and dosing device 10 according to 4 .1 the first dissolution and storage container 40, the first circulation pump 48 and the treatment agent metering pump 73 and the in 4 .1 open loading drawer 90. The loading drawer 90 enables the precise positioning of the multifunctional treatment agent 110 with integrated unit 100 for water treatment intended for this embodiment.

The unit 100 for water treatment integrated in the multifunctional treatment agent 110 can in this embodiment variant be of the cation exchanger type, anion exchanger type and also of the mixed bed ion exchanger type or of the zeolite type. A water treatment agent, i.e. H. Active substances 150 for water treatment of the mixed-bed ion exchanger type has the advantage over cation exchangers and anion exchangers that all types of disruptive components, whether cations or anions, can be removed. This produces almost the quality of distilled water. Active substances 150 for water treatment of the zeolite type work similarly to active substances 150 of the cation exchange type, but are particularly environmentally friendly because they are of natural origin.

At the request of the control unit 140, the first dissolution and storage container 40 is now loaded with the multifunctional treatment agent 110 with an integrated unit 100 for water treatment. For this purpose, the multifunctional treatment agent 110 with integrated unit 100 for water treatment is inserted by the operator into the open loading drawer 90, after which it is closed. Through the precise positioning of the multifunctional treatment means 110 with integrated unit for water treatment 100 and by closing the loading drawer 90, a fluid connection is established between the integrated unit 100 for water treatment and the filling water line 132 by engaging a connecting coupling 112.

The insertion of the multifunctional treatment agent 110 and the closing of the loading drawer 90 are confirmed by the operator on the control unit 140, whereby the cleaner supply and dosing device 10 is put into the filling cycle.

The control unit 140 opens the filling valve 42 at the fluid inlet for a defined time. A quantity of fluid, preferably water, defined in accordance with the feed time for water, now flows via the filling water line 132 into the water treatment unit 100 integrated into the multifunctional treatment agent 110. In the illustrated embodiment according to 4 .1 this is done from a connection coupling 112 connected to the water inlet to the fluid water inlet 102 in an upper region of the integrated water treatment unit 100. When the fluid, preferably water, enters the integrated water treatment unit 100, the fluid comes with the active substances for water treatment 150 in contact. Here, the supplied fluid, preferably water, of undefined quality is optimally prepared by the active substances 150. Treated fluid (filling water) now exits the water treatment unit 100 integrated in the multifunctional treatment means 110 via an outlet 113 for treated fluid in the lower area of the integrated water treatment unit 100 and into the first dissolution and storage container 40. When the corresponding filling level 75 is reached, the filling of the first dissolution and storage container 40 is completed. The control unit 140 now closes the first solenoid valve 42 again.

The control unit 140 now controls the dissolution cycle, i.e. H. the dissolution of the treatment agent present as a solid in the form of the solid rods 45, 65, 68 is initiated. For this purpose, the first circulation pump 48 sucks in fluid and sprays it via a spray line 82 onto the treatment agent present as a solid in the form of the solid rods 45, 65, 68. If these are completely dissolved, a liquefied first treatment agent fluid mixture 47 lies in a defined concentration within the first solution - and storage container 40. The dissolution cycle is now complete.

In the subsequent dosing cycle, the first treatment agent fluid mixture 47, liquefied by external signals or requirements, is fed in portions or continuously to a device to be cleaned in a defined concentration by means of the treatment agent metering pump 73 via the control unit 140. As soon as a minimum filling level is reached in the first dissolving and storage container 40, the operator is asked by the control unit 140 to use a further multifunctional treatment agent 110, after which a new cycle comprising a filling, a dissolving and a dosing cycle is run through can.

The use of a multifunctional treatment agent 110 with an integrated unit 100 for water treatment leads to a consistently identical quality of the treated fluid, which is preferably water, in every dissolution process.

While in the exemplary embodiment 3 The first fluid prepared by the active substances 150 for water treatment will have the best quality for dissolving the first treatment agent in the form of the solid rods 45, 65, 68 of a sales unit, a last fluid prepared by the water treatment unit 3 processed fluid has a poorer quality for dissolving a last solid treatment agent 45,65,68 of a sales unit.

The amount of active ingredients for water treatment 150 in a container 160 3 , will therefore always be higher than in a water treatment unit 100 of a multifunctional treatment agent 110 4 .

In 4 .2 is a multifunctional treatment agent 110 with an integrated unit for water treatment 100 according to 4 .1 shown enlarged. A solid-state treatment agent in the form of a solid rod 45, 65, 68 is connected to the integrated water treatment unit 100 by means of a connecting element 115. As a disposable unit, the integrated unit for water treatment 100 is disposed of together with the connecting element 115 after dissolution of the treatment agent in the form of a solid rod 45, 65, 68. The integrated unit 100 for water treatment is filled with active substances 150 of the type cation exchanger, anion exchanger, mixed-bed ion exchanger or zeolite. The water treatment unit 100 integrated into the multifunctional treatment agent 110 has a connection coupling 112 and an outlet 113 for treated fluid.

When inserting the multi-function treatment agent 110 with integrated unit 100 for water treatment into the positioning drawer 90, as in 4 .1, the multifunctional treatment agent 110 with integrated unit 100 for water treatment is positioned exactly in this. When the positioning drawer 90 is subsequently closed, the unit 100 for water treatment integrated in the multifunctional treatment means 110 is connected to the filling line 132 of the first dissolving and storage container 40 by means of the connecting coupling 112 for the fluid inlet and is connected in a fluid-tight manner. As soon as the filling valve 42 of the cleaner supply and dosing device 10 is closed 4 .1 opens, fluid, preferably water, flows via the filling line 132 of the first dissolution and storage container 40 and the connecting coupling 112 to the integrated unit 100 for water treatment and is prepared for use in the cleaner supply and dosing device 10 before it is transferred out of it the outlet 113 for treated fluid enters the first dissolution and storage container 40.

4 .3 it can be seen that when the loading drawer 90 is closed, the integrated unit 100 for water treatment located on the side of the multifunctional treatment agent 110 is connected to the filling water line 132 via the connecting coupling 112.

How out 4 .3 shows, the multifunctional treatment agent 110 is positioned in such a way that its integrated water treatment unit 100 does not hinder the spraying of the solid treatment agent in the form of solid rods 45, 65, 68 during the dissolution cycle.

According to the representation 5 Treatment agents present as solid bodies in the form of solid rods 45, 65, 68 of different geometries and each without a plastic coating can be seen, as can be used in the previously described exemplary embodiments of the cleaner supply and dosing device 10.

The lack of outer packaging, which is usually a cartridge or a can, significantly reduces the plastic content. The treatment agents in question here are designed as solid bodies in the form of solid rods 45, 65, 68, comprising cleaning, descaling or rinsing agents. Ideally they are in 5 The treatment agents shown schematically in the form of solid rods 45, 65, 68 are different in terms of their color and geometry in order to avoid mixing up the products. By way of example, it should be mentioned that the first solid rod 45, containing detergent, can be made round, the second solid rod 65, containing descaler, can be made triangular and the third solid rod 68, containing rinse aid, can be made square. Of course, other geometries can also be selected.

The invention is not limited to the exemplary embodiments described here and the aspects highlighted therein. Rather, within the range specified by the claims, a large number of modifications are possible, which are within the scope of professional action.
