Definitions
- the invention relates to a method for operating a dishwasher according to the subject matter of claim 1.
- 3in1 combination preparations have been available for use in dishwashing machines, which together contain a cleaning substance, a softening substance and a rinse aid substance and are fed to the washing machine at the same time at a certain point in time are available in compressed tablet form so-called “3in1” tabs as well as “3in1” powders
- the 3in1 combination preparations can be placed in designated dispensers of the dishwasher, in which case they will be at a certain point in time by the washing program of the dishwasher On the other hand, they can also be placed by the user of the dishwasher in the dishwasher, for example in the cutlery basket, before switching on the washing program
- the user of a dishwasher is now generally meh r as a selectable wash program for cleaning the soiled items set in the dishwasher.
- the rinse aid first in a high concentration, that is added overdosed and it is assumed that due to carryover in Spülwasserresten and adhesions of the rinse aid washed dishes, Spül understandinger regardingn and the ceiling of the rinse tank and in the supply lines, the concentration in the rinse cycle still sufficient to achieve a particularly good drying result.
- Another embodiment of the 3-in-1 combination preparation provides that initially only the detergent and the softener dissolve and the rinse aid, which is encapsulated in the 3-in-1 combination preparation, z. B. present in the form of a wax-coated bead, dissolves only temperature and / or pH-dependent during rinsing.
- the rinse aid of the second type is already dissolved.
- the rinse aid of the former type has the particular disadvantage that in the execution of several rinse program sections before rinsing, such.
- cleaning, intermediate rinsing the latter is known to be switched between the program sections cleaning and rinsing, dissolves too quickly and is no longer present in sufficient concentration by multiple rinsing liquid change in the program section rinse.
- Another deficiency in the use of 3-in-1 combination preparations may occur when the user of the dishwasher is dispensing by inserting e.g. B.
- At least one washing program such as, for example, a dishwasher
- a washing program such as, for example, a dishwasher
- the selection means are usually in a control panel of the dishwasher and are well known as such.
- a switchable additional function is provided by the use of combination preparations with multiple drugs such use of a program control is displayed.
- the user-selected washing program such as intensive program, normal program, short program, eco program, is adapted to the use of a combination preparation, the cleaning substance, softening substance and final rinse substance. That is, when the additional function is activated, a corresponding signal is given to the control unit, which automatically carries out the adaptation of the respective user-selected washing program to the use of combination preparations.
- various control routine routines are stored in the microcontroller of the control unit, which is used, and / or on various parameters of the wash programs, such as temperature, duration of a certain Spülprogrammabêtes, Spülillonkeits hypollvolumen, pH u. a. is added or intervened in a defined manner and thereby changed.
- An alternative solution is an additional function, in which switching off a switching means acts according to the invention.
- a specially designed washing program for special use with a combination preparation among other washing programs as such is self-selectable.
- a regeneration function of a softening device is either switched off or changed in comparison to a normal program designed for combination preparations.
- the additional function is designed for the use of a "3in1" combination preparation, this combination preparation containing as effective substances for cleaning the ware substantially only cleanser substance, softening substance and rinse aid substance.
- the "3in1" combination preparation may also have other substances whose direct or indirect influence on the cleaning and drying results of individual rinse program sections or the overall cleaning result of the rinse program are of minor importance. If further active substances of the combination preparation are not expressly mentioned, however, these are, if known and influenceable, included in the subject matter of the invention.
- a switching means for switching on the additional function which is preferably located in the screen carrier of the dishwasher next to other selection means and / or display means.
- a switching means for switching on the additional function, which is preferably located in the screen carrier of the dishwasher next to other selection means and / or display means.
- the switching means diverse known designs, such as rotary selector switch, button or the like are conceivable.
- an actuation of a switching means by a user-dependent selection is possible, which can be switched by selecting in a menu-driven selection device, for example in a display display or networked home appliances via a graphical interface or possibly a voice recognition system.
- a combination preparation in particular of a "3in1" combination preparation
- a combination preparation can be detected in the dishwasher by at least one sensor provided, so that it is possible to distinguish between the sequence of the program and whether a combination preparation works according to the dilution principle or a combination preparation which first applies the rinse aid in the Rinsing phase pH-dependent and / or temperature-dependent dissolution is used.
- concentration and / or pH change and / or changes in the degree of hardness of the rinsing liquid are determined, the conclusions on the concentration of the individual active substances of the "3in1" combination preparation allow, with the result that the program flow at any appropriate time be modified.
- sensors at least one of the sensors is designed as a chemical and / or acoustic and / or thermal and / or optical and / or pneumatic sensor type. These can be designed differently in number and their specific detection property. Furthermore, an evaluation of the sensor signals both with regard to the adaptation of the rinsing program sequence with respect to the use of the "3in1" combination preparation and for the design of the Other parameters of the entire rinse cycle can be used. Furthermore, alternatively, at least one provided chemical sensor with appropriately selected receptors, the detection of z. B. several simultaneously occurring agents, such as cleaners and softeners and / or rinse aid, recognize the use of a combination preparation and signal without the addition of the additional function to the program flow control, the use of a combination preparation.
- the use of a combination preparation is concluded and the program sequence is changed accordingly.
- the use of a sensor which recognizes at least the pH value and / or the temperature and / or the degree of hardness of the rinsing liquid is particularly preferred.
- the intended sensors determine continuously or discontinuously during the program sequence or individual wash program sections whose time courses or times can be predetermined by the program control, of individual program parameters, eg. B. based on an actual target value comparison and / or a difference value and / or the change history of a parameter such as pH, temperature, turbidity, foaming, concentration, water hardness, whether a particular active substance of the combination preparation z. B. exceeds a predetermined minimum or maximum value. Further z. B. as a function of a difference value, the z. B.
- the evaluation of the pH value is currently feasible in such a way that the program section cleaning represents a maximum basic ph value, either in the program section rinsing by a predetermined value must be fallen below, or its change history, eg. B. in a predetermined characteristic field, predefined within predeterminable tolerances or pH jumps (erratic change in pH) can be determined within predefined periods of time or on the other hand, time constants are determined for their occurrence, e.g. after reaching the dissolution temperature of an encapsulated rinse aid.
- such sensor measurement with activated additional function for adapting a Spülprogrammablilleres to the use of a combination preparation for the active intervention in the program flow itself used in selecting a special designed Spülprogrammablilleres have a kind of control function to determine whether during the program actually a combination preparation Use finds or at least one effective substance is present in sufficient concentration at the given time, adjustments of the Spülprogrammablilleres can be optional.
- a suitable method of evaluation of the sensor measurement signals is z.
- at least individual parameter values can be determined within determinable time intervals or time intervals and subjected to an actual nominal value comparison, a difference value formation or a threshold value query or the changes can be made compared to preset values or values determined in the program sequence, all comparison values being shown in tables or as default values in at least one memory unit of the program control are stored.
- this storage unit can also be located outside the dishwasher.
- certain program states can also be stored in the memory unit, whose combination pairings are e.g. not desired are deposited and these can prompt the user to certain actions.
- Such undesirable constellations arise e.g. in the program section prewash if increased foaming and / or significant pH fluctuations occur, or a predetermined rinse aid concentration is exceeded during all program sections or rinse aid concentration jumps occur regardless of a specific temperature or temperature profile. The user can, for example, according to the occurred error situation.
- the loading of a combination preparation in the Dosierkombination make or the program flow is aborted until user-dependent re-commissioning of the dishwasher takes place or the detected as erroneous measurement result is at least indicating.
- z. B. is detected by an acoustic sensor, the case of a tablet from the metering chamber in the washing.
- Other Detection possibilities offer optical sensors, the z. B. register increased foaming or chemical sensors that evaluate the change in the pH of the rinsing fluid.
- an enzymatic cleaner substance having an efficacy temperature limit of about 30 ° C and a rinse aid substance with a dissolution temperature at about 58 ° C is included, with shortened scheduled program sections, and thus shortened solution duration, by short-term, possibly repeated and / or or controlled or regulated power output of the heating means in the pre-washing and / or intermediate rinsing the rinse liquid preferably heated at the end of the respective process section, so that for the following process sections cleaning or rinsing, which are operated with hot rinse liquid, the respective chemical substance their full effectiveness can develop better and longer.
- the dissolution and thus the effectiveness of the cleaner or rinse aid for the duration of each program section is improved.
- the energy supplied is comparable to that of an activation energy.
- the actually used "3in1" combination preparation of the program control is specified as a parameter, eg. B. by input via an image capture
- the z. B. recognizes the barcode of a "3in1" combination preparation or stored in the program store commercially available "3in1" combination preparations can be selected or the use of a specific combination preparation can be entered by the user in any other way, the user-dependent predetermined information on the use of a certain "3in1" combination preparations are either stored up to a changing input information or retrieved at the beginning of each or a defined predetermined time.
- a product unequivocally not identified as a "3in1" combination preparation can deactivate a "3in1" function erroneously selected by the user or when selecting a "3in1" program, an error message is output.
- the program sequence control takes into account the additional function, provides that the program sequence of selected rinse program changes and is adapted in its entire design to the use of a combination preparation.
- individual or several parameters of the various wash program sections pre-wash, clean, intermediate wash, rinse are automatically adjusted in the manner described below, depending on the evaluation of predetermined sensor measurements, or changed in a predefined manner.
- the steps indicated in the method claims in this case do not necessarily represent a requirement for the washing program sequence with regard to their sequence, but can specifically be determined, e.g. be selected depending on the use of a particular combination preparation or type of combination preparation, repeated and / or sequentially switched or followed by other program steps known per se.
- the function of the rinse aid and possibly the detergent dosing in the selected rinse program is hidden when using a "3in1" combination preparation.
- the z. B. sensor-dependent determination of the concentration of the rinse aid to meter these in required amounts, this compensates if necessary, dilution losses of the previous rinse program sections. If, during the selected wash program, further opening times for the metering device are provided for releasing a wide variety of substances, these too are blocked or the time of metering in a particular substance is shifted and / or changed in the metering dosage.
- a softening substance is added to the combination preparation which is to make it unnecessary to soften in a known manner in the dishwasher by means of an intended softening device, then this is also known to be one Dishwasher to be performed regenerating the softener with saturated salt solutions (brine) is not necessary, therefore, in the program flow the Regenerierfunktion, ie the addition of a defined brine volume to the softening device, which is otherwise provided at a defined time of the program sequence hidden.
- the water hardness actually present in the dishwasher if necessary, monitored due to softening with the softening substance of the combination preparation and possibly the Regenerierfunktion the softener switched so that a partial softening of the water through the softening device at a designated hardness sensor that can determine the water hardness of the rinse is made.
- a designated hardness sensor that can determine the water hardness of the rinse.
- the water volume for the regeneration function can be used, in particular in soft water areas, alternatively as a defined volume wholly or partly in the liquid-carrying program sections for dimensioning a predetermined liquid volume.
- the duration of the initially provided program section pre-rinsing can be shortened in order to prevent the encompassed rinse aid and rinse aid active substances from dissolving too early and in the cleaning or rinsing sections are in too low a concentration.
- a rinsing program which provides for two or more pre-rinsing sections, each with complete water change, then by omitting at least one pre-rinsing or reducing to a pre-rinsing section of the program, this already prevents prophylaxis, even without the detection of a combination preparation, from being incorrectly introduced into the dishwasher instead of dissolved in the dosing combination combined preparations dissolves too early.
- the pre-rinsing process section is shortened or completely omitted, this reduces the time of loading the ware with water, the process of dissolving heavy soiling, which may have long adhered to the ware, is thereby shortened or completely eliminated. This is not conducive to good cleaning results in some cases of contamination. Therefore, in such cases, the process section cleaning is preferably extended by the duration of the process section by which the pre-rinse process section has been shortened. Thus, the dissolution of the dirt particles is at least partially moved into the cleaning procedure.
- the number of intermediate rinsing sections between the cleaning and rinsing program sections is reduced to an intermediate rinsing section, which essentially has the task of eliminating occasionally trapped dirt particles and chemical residues of the cleaning.
- the intermediate rinsing can be operated with a reduced maximum rinsing liquid volume compared to the maximum intended rinsing liquid volume of the program section cleaning, so that the concentration of the dissolved rinse aid is higher than with the same size rinsing liquid volume as in cleaning.
- the intermediate rinsing section may possibly be completely dispensed with.
- the energy fed in during the process sections which are operated with hot rinsing liquid is removed.
- the energy fed in during the process sections which are operated with hot rinsing liquid is removed.
- the circulation pump can be provided by repeated switching on and off the circulation pump with different determinable and / or predefinable duration of the on and off state the circulation pump to bring the rinsing liquid in the manner of a pulse rinse on the dishes.
- the circulation of the rinsing liquid and thus the application of the ware is interrupted with rinsing liquid.
- This type of pulse purging is briefly described with a sequence of spraying, pausing, splattering, pausing, splashing, pausing, etc.
- the intermediate rinse may be provided in dependence of the measurement of turbidity and / or the content of rinse aid in the rinsing liquid, a dilution step.
- the dilution step causes a partial volume of the rinsing liquid, which was used during the intermediate rinsing, to continue to be used in the subsequent rinsing process section and to be mixed with fresh rinsing liquid to be supplied.
- the loss in particular of rinse aid against a complete pumping and filling of rinsing liquid is reduced.
- the temperature in the process sections preceding the program section rinsing, preferably in the process section cleaning is preferably reduced to a temperature below the dissolution temperature of the rinse aid, preferably below 58 ° C.
- a selected intensive program which usually operates the cleaning section with temperatures between 58 and 70 ° C, prevents that when using a combination preparation with temperature-dependent release of the rinse aid substance this possibly already dissolves here and therefore present in the program section rinse in too low a concentration.
- the temperature control of the rinsing liquid during a selected rinsing process which has been adapted to the use of combination preparations automatically, as mentioned above, determined on the one hand by the dissolution temperatures of the individual chemical substances.
- the rinsing liquid is not heated by switching on intended heating means, so that the rinsing liquid essentially depends on the water inlet temperature.
- the rinsing liquid is actively heated as a result of switching on the heating means provided and passive in the intermediate rinsing program section without connecting these heating means, ie. H. by removing energy from the heat capacity of the dishwasher, heated significantly to a temperature below the dissolution temperature of a temperature-dependent rinse aid.
- parts of the wash program with selected "3in1" function run completely or partially according to a defined predetermined program or detection and evaluation of certain parameters, eg. B. by sensors, in a suitable manner to the actual situation with respect to a predetermined desired situation completely or partially adapt.
- connection of the "3in1" function or the selection of a “3in1" purging program can also be switched on, if necessary, in the case of networked household appliances which are operated independently of location by a central computer not located in the dishwasher.
- a special "3in1" flushing program can be provided, which is adapted from the outset to the use of combination preparations, especially those containing cleaners, softeners and rinse aid at the same time.
- This "3in1" purging program is selected directly by the user of the dishwasher and is characterized by the following essential process steps, the case mentioned but not necessarily sequence of process steps represents a possible Spülprogrammablauf without the final program section drying:
- the pre-rinse is done with cold water, which is thus essentially dependent on the water supply temperature, for an extremely short period of 2 to 5 min., Preferably 2 to 3 min. During this time, mainly fresh soiling can be detached and softened dirt can be softened.
- the liquid can be provided with heavy contamination one or more dilution steps of the rinsing liquid, wherein a dilution step due to the brevity of the pre-rinsing, preferably at the end of the pre-rinsing is provided. If no dilution step takes place at the end of the pre-rinse, the rinse liquid is completely changed before the next program section.
- the freshly supplied rinsing liquid which may also be diluted and thus contaminated to a certain extent, is now heated in the cleaning process section to a temperature which is below the dissolution temperature of the rinse aid, preferably between 40 and 57 ° C.
- the combination preparation is preferably supplied to the rinsing container by the dosing device within the first third of the program section cleaning, provided that the combination preparation is not by the user before starting the rinsing-rinsing program in the washing, z. B. in the cutlery basket was inserted.
- the rinsing liquid is circulated in the washing during cleaning about 10 to 30 minutes and completely pumped or diluted at the end of the cleaning process section. This decision can be made dependent on an optional turbidity measurement of the rinsing liquid.
- the process section cleaning is followed by a process section intermediate rinsing in which the fresh or diluted rinsing liquid now present is passively, i. H. is heated exclusively by energy removal of the heat capacity of the dishwasher, so that it removes during their circulation still existing residual debris and chemical residues of the process section cleaning.
- the circulation of the rinsing liquid takes place in the intermediate rinsing section for a period of about 2 to 10 minutes.
- the intermediate rinsing can also be operated as pulse rinsing with a reduced maximum rinsing liquid volume with respect to the maximum rinsing liquid volume of the cleaning.
- the intermediate flushing stage ends with a complete or partial drainage.
- a defined rinsing liquid volume is supplied to the rinsing container. This can be fixed from the outset and / or set variably in dependence of various parameters.
- a dependent variable is the concentration of the rinse aid actually present in the rinse liquid, since this has an immediate effect on the rinse aid result and thus on the subsequently achievable drying result of the ware.
- concentration of the rinse aid actually present in the rinse liquid, since this has an immediate effect on the rinse aid result and thus on the subsequently achievable drying result of the ware.
- the concentration of the rinse aid at the beginning of the program section rinsing can be adjusted to a predetermined concentration by supplying a defined rinse liquid volume.
- the rinsing liquid with rinse aid already dissolved, as well as the rinse aid still to be dissolved is now preferably heated to a dissolution temperature above the dissolution temperature of a rinse aid dissolving in pH and / or temperature.
- This dissolution temperature is currently above 58 ° C (for the "3in1" combination preparation Calgonit Powerballs®).
- the rinsing liquid is heated and circulated.
- the rinsing liquid is removed as far as possible by pumping out of the rinsing container.
- the Spülcieserdecke, the Spül variouser is removed in, following the program section rinse, program section drying.
- the drying is preferably carried out as condensation drying.
- at least one circulating air blower is switched on in the first third of this program section.
- the intermediate rinsing during the liquid-carrying process sections can preferably be designed as pulse rinses, ie, during the process section intermediate rinsing, the circulation pump is repeatedly switched on and off for a predefinable or determinable duration.
- the duration of switching on the circulation pump and the switching off of the circulation pump is dependent on a level of Spülillonkeitsitate in the washing, which corresponds to a lower level, at which the circulating pump sucks no air. Due to the above-mentioned limited factor, there are further dependencies on the rotational speed of the circulation pump, which withdraws more rinsing liquid from the sump as the rotational speed increases.
- the design of the pulses of switching on and off of the circulation pump is adjustable depending on a turbidity measurement of the rinsing liquid, so the duration of switching on the circulation pump can be shortened compared to the duration of turning off the circulation pump at low degree of contamination and extended accordingly with increased degree of contamination.
- the maximum existing rinsing liquid volume during a liquid-carrying process section preferably set in the process section intermediate rinsing defined.
- a combination preparation which contains a rinse aid which has a temperature and / or pH-dependent dissolution behavior
- a certain pH preferably in the neutral pH range

- the single figure shows a schematic of the individual process sections of a washing program sequence. It is assumed that the water of the supply line is substantially soft and thus has a low degree of hardness.
- the rinsing liquid should reach a temperature of about 55 ° C, which at the time of the invention, a temperature below the dissolution temperature of the rinse aid of pHund temperature-dependent dissolvable 3inl combination preparation, such as Calgonit Powerballs® corresponds.
- the "3in1" combination preparation is added, preferably during the supply of rinsing liquid (indicated by arrow 3 in1).
- the rinsing liquid is circulated at the maximum predetermined temperature for about 10 to 30 minutes in the washing and thereby applied to the dishes to be cleaned. At the end of the program section cleaning, the rinsing liquid is almost completely removed from the rinsing container (indicated by arrow VR). The rinsing liquid volume is refilled for a subsequent program section intermediate rinsing and heated and circulated exclusively by removing energy stored in the heat capacity of the dishwasher.
- the maximum volume of rinsing liquid supplied can be varied as a function of a turbidity measurement and / or a concentration measurement of existing rinse aid which operates on the dilution principle.
- the rinsing liquid volume is preferably increased in the case of a high degree of contamination and / or a high degree of concentration of the rinse aid and / or strongly basic medium of the rinsing liquid.
- the rinsing liquid volume is lowered.
- the process section intermediate rinsing passes into the program section rinsing after a dilution step or after a complete pumping, not shown, for example depending on the degree of turbidity.
- the rinsing liquid volume is at least partially increased and preferably reaches the maximum rinsing liquid volume of the program section cleaning.
- the rinsing liquid volume can also be adjusted precisely to a predeterminable concentration range of the rinse aid by appropriately evaluated measurement results of provided sensors.

Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Geschirrspülmaschine gemäß dem Gegenstand des Anspruches 1.The invention relates to a method for operating a dishwasher according to the subject matter of
Es sind nunmehr seit geraumer Zeit sog. "3in1"-Kombinationspräparate" zur Verwendung in Geschirrspülmaschinen erhältlich, die zusammen eine Reinigungssubstanz, eine Enthärtungssubstanz und eine Klarspülsubstanz enthalten und dem Spülbehälter der Geschirrspülmaschine zu einem bestimmten Zeitpunkt gleichzeitig zugeführt werden. Diese "3in1"-Kombinationspräparate sind in gepresster Tablettenform sog. "3in1"-Tabs als auch als "3in1"-Pulver verfügbar. Die 3in1-Kombinationspräparate können in vorgesehene Dosiervorrichtungen der Geschirrspülmaschine eingelegt werden, in diesem Fall werden sie zu einem bestimmten Zeitpunkt, der durch den Spülprogrammablauf der Geschirrspülmaschine bestimmt wird, dem Spülbehälter zudosiert. Andererseits können sie auch durch den Benutzer der Geschirrspülmaschine in die Geschirrspülmaschine, z. B. in den Besteckkorb, vor dem Einschalten des Spülprogrammes gelegt werden. Dem Benutzer einer Geschirrspülmaschine steht heute im Allgemeinen mehr als ein auswählbares Spülprogramm zum Reinigen des in die Geschirrspülmaschine eingestellten verschmutzten Spülgutes zur Verfügung. Als auswählbare Spülprogramme sind hinlänglich Programme unter den Namen Kurzprogramm, Normalprogramm, Intensivprogramm, Ökoprogramm, für die auch verschiedenste synonyme Begriffsbildungen existieren, bekannt. Seit der Verwendung von "3in1"-Kombinationspräparaten durch den Benutzer der Geschirrspülmaschine haben sich die Kundenbeschwerden bei den Herstellern der Geschirrspülmaschinen gehäuft. Denn die Reinigungs- und/oder Trocknungsergebnisse des in der Geschirrspülmaschine gereinigten Spülgutes haben sich teilweise dramatisch bei Verwendung von 3in1-Präparaten gegenüber herkömmlicher einzelner Zudosierung der entsprechenden Substanzen verschlechtert. Als besonders problematisch hat sich erwiesen, dass zum einen die Benutzer die vorgeschriebene Lokalisierung des 3in1-Kombinationspräparates in der Geschirrspülmaschine nicht beachten, so dass manche die 3in1-Tabs in die Geschirrspülmaschine legen, während durch den Hersteller eine Benutzung ausschließlich per Dosiervorrichtung vorgeschrieben ist. Ferner sind die Angaben der Hersteller der "3in1"-Kombinationspräparate bzgl. der Auswahl eines geeigneten Spülprogrammes nicht sachgerecht, da der Benutzer der Geschirrspülmaschine im Allgemeinen zwar weiß, welches Spülprogramm er in Abhängigkeit des Verschmutzungs- und Antrocknungsgrades der Schmutzpartikel auswählen muss, jedoch keine intimere Kenntnis über den Ablauf des Spülprogrammes an sich hat. Diese Kenntnis impliziert der Hersteller des 3in1-Kombinationspräparates beim Benutzer und lässt dabei ferner völlig unberücksichtigt, dass am Markt verschiedene "3in1"-Kombinationspräparate vorhanden sind, die sich in Abhängigkeit verschiedenster Parameter unterschiedlich auflösen und dementsprechend zu verschiedenen Zeitpunkten ihre höchste Wirksamkeit erzielen. So arbeiten einige am Markt erhältliche 3in1-Kombinationspräparate nach einem sog. "Verdünnungsprinzip" (auch als Carry over-Prinzip bekannt), d. h. zu Beginn des Reinigens wird das 3in1-Kombinationspräparat zugesetzt und beginnt sich aufzulösen. Dabei wird hauptsächlich der Klarspüler zunächst in einer hohen Konzentration, d. h. überdosiert zugesetzt und es wird davon ausgegangen, dass infolge von Verschleppungen in Spülwasserresten und Adhäsionen des gelösten Klarspülers an Spülgut, Spülbehälterwänden und der Decke des Spülbehälters als auch in den Zuleitungen die Konzentration im Klarspülgang noch ausreicht, um ein besonders gutes Trocknungsergebnis zu erzielen. Eine andere Ausführungsform des 3in1-Kombinationspräparates sieht vor, dass sich zunächst nur der Reiniger und der Enthärter auflösen und der Klarspüler, der im 3in1-Kombinationspräparat abgekapselt, z. B. in Form einer wachsumhüllten Perle vorliegt, sich erst temperatur- und/oder pH-Wert-abhängig während des Klarspülens auflöst. Bei der Verwendung eines Spülprogrammes, welches schon im Programmabschnitt Reinigen mit hohen Temperaturen arbeitet und/oder wo die Dauer des Reinigungsvorganges sehr lang gewählt wird, was im Allgemeinen bei einem Intensivprogramm üblich ist, wird der Klarspüler der zweitgenannten Art jedoch schon aufgelöst. Der Klarspüler der erstgenannten Art hat insbesondere den Nachteil, dass bei dem Ausführen mehrerer Spülprogrammabschnitte vor dem Klarspülen, wie z. B. Reinigen, Zwischenspülen, wobei letzterer bekannterweise zwischen die Programmabschnitte Reinigen und Klarspülung geschaltet ist, sich zu schnell auflöst und dabei durch mehrfachen Spülflüssigkeitswechsel im Programmabschnitt Klarspülen nicht mehr in ausreichender Konzentration vorhanden ist. Ein weiterer Mangel bei der Verwendung von 3in1-Kombinationspräparaten kann auftreten, wenn der Benutzer der Geschirrspülmaschine die Zudosierung durch Einlegen, z. B. eines 3in1-Tabs, vor dem Start des Spülprogrammes an irgendeiner Stelle des Geschirrspülers, jedoch nicht in die Dosierkombination vornimmt. Hierbei beginnt z. B. im Programmabschnitt Vorspülen zumindest der Reiniger und Enthärter sich zu lösen, wobei im Allgemeinen in Laborversuchen festgestellt werden konnte, dass das Auflösungsverhalten der 3in1-Kombinationspräparaten auch bei Wasser, welches im Wesentlichen Zuleitungstemperatur aufweist, sehr gut ist. Durch Abpumpen steht den nachfolgenden Programmabschnitte Reinigen, ggf. vorgesehenen Programmabschnitten Zwischenspülen, Klarspülen, die Substanzen des 3in1-Kombinationspräparates in einer geringeren Konzentration zur Verfügung, was direkte Auswirkung sowohl auf das Reinigungs- als auch auf das Trocknungsergebnis des Spülgutes hat und dieses im Allgemeinen verschlechtert.For a long time now, so-called "3in1" combination preparations have been available for use in dishwashing machines, which together contain a cleaning substance, a softening substance and a rinse aid substance and are fed to the washing machine at the same time at a certain point in time are available in compressed tablet form so-called "3in1" tabs as well as "3in1" powders The 3in1 combination preparations can be placed in designated dispensers of the dishwasher, in which case they will be at a certain point in time by the washing program of the dishwasher On the other hand, they can also be placed by the user of the dishwasher in the dishwasher, for example in the cutlery basket, before switching on the washing program The user of a dishwasher is now generally meh r as a selectable wash program for cleaning the soiled items set in the dishwasher. Programs which can be selected as wash programs are well-known under the name short program, normal program, intensive program, eco program, for which also very different synonymous conceptual formations exist. Since the use of "3in1" combination preparations by the user of the dishwasher, customer complaints have accumulated among manufacturers of dishwashers. For the cleaning and / or drying results of the items to be cleaned in the dishwasher worsened, in some cases dramatically, when using 3-in-1 preparations in comparison with conventional individual metered addition of the corresponding substances. It has proven to be particularly problematic that, on the one hand, the users do not pay attention to the prescribed localization of the 3-in-one combination preparation in the dishwasher, so that some place the 3-in-1 tabs in the dishwasher, whereas the manufacturer requires use exclusively by means of a dosing device. Furthermore, the information provided by the manufacturers of the "3in1" combination preparations with regard to the selection of a suitable washing program is inappropriate, since the user of the dishwasher generally knows which washing program he must select depending on the degree of dirtying and drying of the dirt particles, but no more intimate Knowledge about the course of the washing program has. This knowledge implies the manufacturer of the 3-in-1 combination preparation at the user and also completely disregards the fact that various "3in1" combination preparations are present on the market, which dissolve differently depending on various parameters and accordingly achieve their highest effectiveness at different times. Thus, some 3in1 combination preparations available on the market operate according to a so-called "dilution principle" (also known as the carry-over principle), ie at the beginning of the cleansing, the 3-in-one combination preparation is added and begins to dissolve. It is mainly the rinse aid first in a high concentration, that is added overdosed and it is assumed that due to carryover in Spülwasserresten and adhesions of the rinse aid washed dishes, Spülbehälterwänden and the ceiling of the rinse tank and in the supply lines, the concentration in the rinse cycle still sufficient to achieve a particularly good drying result. Another embodiment of the 3-in-1 combination preparation provides that initially only the detergent and the softener dissolve and the rinse aid, which is encapsulated in the 3-in-1 combination preparation, z. B. present in the form of a wax-coated bead, dissolves only temperature and / or pH-dependent during rinsing. When using a wash program, which already works in the program section cleaning at high temperatures and / or where the duration of the cleaning process is chosen very long, which is common in an intensive program, the rinse aid of the second type is already dissolved. The rinse aid of the former type has the particular disadvantage that in the execution of several rinse program sections before rinsing, such. As cleaning, intermediate rinsing, the latter is known to be switched between the program sections cleaning and rinsing, dissolves too quickly and is no longer present in sufficient concentration by multiple rinsing liquid change in the program section rinse. Another deficiency in the use of 3-in-1 combination preparations may occur when the user of the dishwasher is dispensing by inserting e.g. B. a 3in1 tabs, before the start of the wash program at any point of the dishwasher, but not in the Dosierkombination makes. This begins z. As in the program section pre-rinsing at least the cleaner and softener to solve, which was generally found in laboratory experiments that the dissolution behavior of the 3-in-1 combination preparations is also very good for water, which has substantially supply temperature. By pumping the following program sections cleaning, possibly provided program sections intermediate rinsing, rinsing, the substances of the 3in1 combination preparation in a lower concentration available, which has a direct effect on both the cleaning and the drying result of the items to be washed and this generally worsens.
Es ist Aufgabe der Erfindung, ein Verfahren zum Betreiben einer Geschirrspülmaschine vorzuschlagen, das zumindest einen der vorstehend genannten Nachteile überwindet und ein Spülprogramm bereitstellt, welches auf die Verwendung von Kombinationspräparaten mit mehreren Wirkstoffen angepasst ist oder angepasst wird, wobei dem Benutzer die grundsätzliche Verwendung der bisher bekannten Spülprogramme weiterhin ermöglicht werden soll.It is an object of the invention to provide a method for operating a dishwasher, which overcomes at least one of the aforementioned disadvantages and provides a washing program, which is adapted to the use of combination preparations with multiple active substances or adapted, the user the basic use of the previously known washing programs continue to be possible.
Vorstehend genannte Aufgabe wird durch ein Verfahren gemäß den Merkmalen des Anspruchs 1 gelöst.The above object is achieved by a method according to the features of
Gemäß dem Verfahren der vorgeschlagenen Erfindung ist an einer Geschirrspülmaschine zumindest ein Spülprogramm, wie z. B. Intensivprogramm, Normalprogramm, Kurzprogramm, Ökoprogramm, durch den Benutzer der Geschirrspülmaschine auswählbar. Die Auswahlmittel befinden sich zumeist in einer Bedienblende der Geschirrspülmaschine und sind als solche hinlänglich bekannt.According to the method of the proposed invention, at least one washing program, such as, for example, a dishwasher, is provided on a dishwasher. B. Intensive program, normal program, short program, eco program, selectable by the user of the dishwasher. The selection means are usually in a control panel of the dishwasher and are well known as such.
Erfindungsgemäß ist eine zuschaltbare Zusatzfunktion vorgesehen, durch die bei der Verwendung von Kombinationspräparaten mit mehreren Wirkstoffen eine derartige Verwendung einer Programmsteuerung angezeigt wird. Dies hat zur Folge, dass das durch den Benutzer ausgewählte Spülprogramm, wie Intensivprogramm, Normalprogramm, Kurzprogramm, Ökoprogramm, auf die Verwendung eines Kombinationspräparates, das Reinigungssubstanz, Enthärtungssubstanz und Klarspülsubstanz umfasst, selbsttätig angepasst wird. Das heißt, bei eingeschalteter Zusatzfunktion wird ein entsprechendes Signal an die Steuereinheit gegeben, die selbsttätig die Anpassung des jeweils benutzerabhängig ausgewählten Spülprogrammes auf die Benutzung von Kombinationspräparaten vornimmt. Hierzu sind beispielsweise verschiedene Steuerablaufroutinen im Microcontroller der Steuereinheit hinterlegt, auf die zurückgegriffen wird, und/oder auf verschiedene Parameter der Spülprogramme, wie Temperatur, Dauer eines bestimmten Spülprogrammabschnittes, Spülflüssigkeitsfüllvolumen, pH-Wert u. a. wird definiert zu- bzw. eingegriffen und diese hierdurch verändert. Eine alternative Lösung stellt eine Zusatzfunktion dar, bei der ein Abschalten eines Schaltmittels erfindungsgemäß wirkt. In einer weiteren Ausführungsform der Erfindung ist ein speziell gestaltetes Spülprogramm zur besonderen Verwendung mit einem Kombinationspräparat unter anderen Spülprogrammen als solches selbst auswählbar. Bei der Erfindung ist durch Zuschalten der Zusatzfunktion eine Regenerierfunktion einer Enthärtereinrichtung entweder abgeschaltet oder im Vergleich zu einem nicht für Kombinationspräparate ausgelegten Normalprogramm verändert.According to the invention a switchable additional function is provided by the use of combination preparations with multiple drugs such use of a program control is displayed. As a result, the user-selected washing program, such as intensive program, normal program, short program, eco program, is adapted to the use of a combination preparation, the cleaning substance, softening substance and final rinse substance. That is, when the additional function is activated, a corresponding signal is given to the control unit, which automatically carries out the adaptation of the respective user-selected washing program to the use of combination preparations. For this purpose, for example, various control routine routines are stored in the microcontroller of the control unit, which is used, and / or on various parameters of the wash programs, such as temperature, duration of a certain Spülprogrammabschnittes, Spülflüssigkeitsfüllvolumen, pH u. a. is added or intervened in a defined manner and thereby changed. An alternative solution is an additional function, in which switching off a switching means acts according to the invention. In a further embodiment of the invention, a specially designed washing program for special use with a combination preparation among other washing programs as such is self-selectable. In the invention, by switching on the additional function, a regeneration function of a softening device is either switched off or changed in comparison to a normal program designed for combination preparations.
Bevorzugt ist die Zusatzfunktion auf die Verwendung eines "3in1"-Kombinationspräparates ausgelegt, wobei dieses Kombinationspräparat als wirkspezifische Substanzen zur Reinigung des Spülgutes im Wesentlichen nur Reinigersubstanz, Enthärtungssubstanz und Klarspülersubstanz enthält. Unabhängig von diesen Bestandteilen kann das "3in1"-Kombinationspräparat auch weitere Substanzen aufweisen, deren direkter oder indirekter Einfluss auf das Reinigungs- und Trocknungsergebnis einzelner Spülprogrammabschnitte bzw. das Gesamtreinigungsergebnis des Spülprogrammes von untergeordneter Bedeutung sind. Sofern weitere wirkspezifische Substanzen des Kombinationspräparates nicht ausdrücklich genannt sind, sind diese jedoch sofern bekannt und beeinflussbar vom Erfindungsgegenstand mit umfasst.Preferably, the additional function is designed for the use of a "3in1" combination preparation, this combination preparation containing as effective substances for cleaning the ware substantially only cleanser substance, softening substance and rinse aid substance. Regardless of these components, the "3in1" combination preparation may also have other substances whose direct or indirect influence on the cleaning and drying results of individual rinse program sections or the overall cleaning result of the rinse program are of minor importance. If further active substances of the combination preparation are not expressly mentioned, however, these are, if known and influenceable, included in the subject matter of the invention.
Es ist ferner ein Schaltmittel zum Zuschalten der Zusatzfunktion umfasst, wobei dieses bevorzugt im Blendenträger der Geschirrspülmaschine neben anderen Auswahlmitteln und/oder Anzeigemitteln lokalisiert ist. Eine andere Möglichkeit das Schaltmittel anzuordnen, bietet die Dosiereinrichtung des Kombinationspräparates, in die das Kombinationspräparat bevorzugt eingefüllt ist. In der Ausgestaltung des Schaltmittels sind verschiedenartigste bekannte Ausgestaltungen, wie Drehwahlschalter, Taster oder dergleichen denkbar. Ferner ist auch eine Betätigung eines Schaltmittels durch eine benutzerabhängige Auswahl möglich, die durch Auswahl in einer menügeführten Auswahlvorrichtung, beispielsweise in einem Anzeigedisplay oder bei vernetzten Hausgeräten über eine graphische Oberfläche oder ggf. ein Spracherkennungssystem zugeschaltet werden kann.It is further comprises a switching means for switching on the additional function, which is preferably located in the screen carrier of the dishwasher next to other selection means and / or display means. Another possibility to arrange the switching means, the metering device of the combination preparation, in which the combination preparation is preferably filled. In the embodiment of the switching means diverse known designs, such as rotary selector switch, button or the like are conceivable. Furthermore, an actuation of a switching means by a user-dependent selection is possible, which can be switched by selecting in a menu-driven selection device, for example in a display display or networked home appliances via a graphical interface or possibly a voice recognition system.
In der Geschirrspülmaschine ist durch zumindest einen vorgesehenen Sensor die Verwendung eines Kombinationspräparates insbesondere eines "3in1"-Kombinationspräparates detektierbar, so dass für die Programmablaufgestaltung zum einen unterscheidbar ist, ob ein Kombinationspräparat nach dem Verdünnungsprinzip arbeitet, oder ein Kombinationspräparat, welches den Klarspüler erst in der Klarspülphase pH-Wert- und/oder temperaturabhängig auflöst, verwendet wird. Zum anderen können bei wiederholter Sensormessung während des gesamten Spülprogrammablaufes z. B. Konzentrations- und/oder pH-Wert-Veränderung und/oder Änderungen des Härtegrades der Spülflüssigkeit festgestellt werden, die Rückschlüsse auf die Konzentration der einzelnen Wirksubstanzen des "3in1"-Kombinationspräparates zulassen, mit der Folge, dass der Programmablauf zu jedem geeigneten Zeitpunkt modifiziert werden.The use of a combination preparation, in particular of a "3in1" combination preparation, can be detected in the dishwasher by at least one sensor provided, so that it is possible to distinguish between the sequence of the program and whether a combination preparation works according to the dilution principle or a combination preparation which first applies the rinse aid in the Rinsing phase pH-dependent and / or temperature-dependent dissolution is used. On the other hand, with repeated sensor measurement during the entire Spülprogrammablaufes z. B. concentration and / or pH change and / or changes in the degree of hardness of the rinsing liquid are determined, the conclusions on the concentration of the individual active substances of the "3in1" combination preparation allow, with the result that the program flow at any appropriate time be modified.
Als Sensoren ist zumindest einer der Sensoren als chemischer und/oder akustischer und/oder thermischer und/oder optischer und/oder pneumatischer Sensortyp ausgebildet. Diese können in Anzahl und ihrer spezifischen Detektionseigenschaft unterschiedlich gestaltet sein. Ferner ist eine Auswertung der Sensorsignale sowohl hinsichtlich der Anpassung des Spülprogrammablaufes bezüglich der Verwendung des "3in1"-Kombinationspräparates als auch für die Gestaltung der sonstigen Parameter des gesamten Spülprogrammablaufes verwertbar. Ferner kann alternativ zumindest ein vorgesehener chemischer Sensor mit entsprechend ausgewählten Rezeptoren, der zur Detektion z. B. mehrerer gleichzeitig auftretender Wirkstoffe, wie Reiniger und Enthärter und/oder Klarspüler, die Verwendung eines Kombinationspräparates erkennen und auch ohne ein Zuschalten der Zusatzfunktion an die Programmablaufsteuerung die Verwendung eines Kombinationspräparates signalisieren. Durch ggf. wiederholte Kontrollmessungen und/oder im Abgleich mit anderen Sensormessungen während des Programmablaufes wird auf die Verwendung eines Kombinationspräparates geschlossen und der Programmablauf entsprechend verändert. Besonders bevorzugt ist derzeit die Verwendung eines Sensors, der zumindest den pH-Wert- und/oder die Temperatur und/oder den Härtegrad der Spülflüssigkeit erkennt.As sensors at least one of the sensors is designed as a chemical and / or acoustic and / or thermal and / or optical and / or pneumatic sensor type. These can be designed differently in number and their specific detection property. Furthermore, an evaluation of the sensor signals both with regard to the adaptation of the rinsing program sequence with respect to the use of the "3in1" combination preparation and for the design of the Other parameters of the entire rinse cycle can be used. Furthermore, alternatively, at least one provided chemical sensor with appropriately selected receptors, the detection of z. B. several simultaneously occurring agents, such as cleaners and softeners and / or rinse aid, recognize the use of a combination preparation and signal without the addition of the additional function to the program flow control, the use of a combination preparation. By repeated control measurements and / or in comparison with other sensor measurements during the program sequence, the use of a combination preparation is concluded and the program sequence is changed accordingly. At present, the use of a sensor which recognizes at least the pH value and / or the temperature and / or the degree of hardness of the rinsing liquid is particularly preferred.
Der/die vorgesehenen Sensoren ermitteln kontinuierlich oder diskontinuierlich während des Programmablaufes oder einzelner Spülprogrammabschnitte deren Zeitverläufe bzw. Zeitpunkte durch die Programmsteuerung vorgebbar sind, von einzelnen Programmparametern, z. B. anhand eines Ist-Soll-Wertevergleiches und/oder eines Differenzwertes und/oder des Änderungsverlaufes eines Parameters wie pH-Wert, Temperatur, Trübung, Schaumbildung, Konzentration, Wasserhärte, ob eine bestimmte Wirksubstanz des Kombinationspräparates z. B. einen vorgegebenen minimalen oder maximalen Wert über- oder unterschreitet. Ferner z. B. in Abhängigkeit eines Differenzwertes, der sich z. B. herstellerabhängig aus dem "3in1"-Kombinationspräparat selbst ergeben kann, als auch im Hinblick auf andere typische Parameter wie Konzentrationssprünge, Auflösetemperaturen bzw. Parameterkombinationen wie pH-Wert und Konzentration oder Konzentration und Temperatur des Spülprogrammablaufes ergeben. Für einen bestimmbaren Zeitabschnitt eines Spülprogrammablaufes oder über die gesamte Dauer des Spülprogrammes wird ebenfalls die Änderung zumindest eines Parameters des Spülprogrammes erfasst und ausgewertet. So sind z. B. hinsichtlich des Verlaufes des pH-Wertes der Spülflüssigkeit Rückschlüsse auf die Konzentration der einzelnen Wirksubstanzen des "3in1"-Kombinationspräparates möglich. So ist derzeit die Auswertung des pH-Wertes derart durchführbar, dass der Programmabschnitt Reinigen einen maximal basischen ph-Wert darstellt, entweder im Programmabschnitt Klarspülen um einen vorgegebenen Wert unterschritten werden muss, oder aber dessen Änderungsverlauf, z. B. in einem vorgegebenen Kennlinienfeld, innerhalb vorgebbarer Toleranzen vordefiniert ist oder pH-Wertsprünge (sprunghafte Änderung des pH-Wertes) innerhalb vordefinierter Zeitabschnitte ermittelt werden oder andererseits Zeitkonstanten für deren Auftreten ermittelt werden, z.B. nach dem Erreichen der Auflösetemperatur eines gekapselten Klarspülers. Erfindungsgemäß werden derartige Sensormessung bei eingeschalteter Zusatzfunktion zur Anpassung eines Spülprogrammablaufes an die Verwendung eines Kombinationspräparates für den aktiven Eingriff in den Programmablauf an sich verwendet, bei Auswahl eines speziellen gestalteten Spülprogrammablaufes haben diese zunächst eine Art Kontrollfunktion, um festzustellen, ob während des Programmablaufes tatsächlich ein Kombinationspräparat Verwendung findet oder zumindest eine wirkspezifische Substanz zur vorgegebenen Zeit in ausreichender Konzentration vorhanden ist, Anpassungen des Spülprogrammablaufes können optional erfolgen.The intended sensors determine continuously or discontinuously during the program sequence or individual wash program sections whose time courses or times can be predetermined by the program control, of individual program parameters, eg. B. based on an actual target value comparison and / or a difference value and / or the change history of a parameter such as pH, temperature, turbidity, foaming, concentration, water hardness, whether a particular active substance of the combination preparation z. B. exceeds a predetermined minimum or maximum value. Further z. B. as a function of a difference value, the z. B. depending on the manufacturer from the "3in1" combination preparation itself, as well as with regard to other typical parameters such as concentration jumps, dissolution temperatures or parameter combinations such as pH and concentration or concentration and temperature of the Spülprogrammablaufes result. For a determinable period of a wash program sequence or over the entire duration of the wash program, the change of at least one parameter of the wash program is also detected and evaluated. So z. B. with regard to the course of the pH of the rinsing liquid conclusions about the concentration of the individual active substances of the "3in1" combination preparation possible. Thus, the evaluation of the pH value is currently feasible in such a way that the program section cleaning represents a maximum basic ph value, either in the program section rinsing by a predetermined value must be fallen below, or its change history, eg. B. in a predetermined characteristic field, predefined within predeterminable tolerances or pH jumps (erratic change in pH) can be determined within predefined periods of time or on the other hand, time constants are determined for their occurrence, e.g. after reaching the dissolution temperature of an encapsulated rinse aid. According to the invention, such sensor measurement with activated additional function for adapting a Spülprogrammablaufes to the use of a combination preparation for the active intervention in the program flow itself used in selecting a special designed Spülprogrammablaufes these have a kind of control function to determine whether during the program actually a combination preparation Use finds or at least one effective substance is present in sufficient concentration at the given time, adjustments of the Spülprogrammablaufes can be optional.
Eine geeignete Methode der Auswertung der Sensormesssignale ist z. B. den Wert bzw. die Änderung bestimmter Parameter des Spülprogrammes wie Trübung, pH-Wert, Schaumbildung, Konzentration, Wasserhärte u. a. einzeln als auch in geeigneten Kombinationen zu charakteristischen Zeitpunkten des Spülprogrammablaufes, hinsichtlich ihres qualitativen und quantitativen Auftretens als auch ihrer Verzögerungszeiten untereinander zu ermitteln. Hierzu können innerhalb bestimmbarer Zeitabschnitte oder Zeitabstände zumindest einzelne Parameterwerte ermittelt und diese einem Ist-Soll-Wertabgleich, einer Differenzwertbildung oder einer Schwellwertabfrage unterzogen werden bzw. die Änderungen gegenüber voreingestellten oder im Programmablauf ermittelten Werte vorgenommen werden, wobei sämtliche Vergleichswerte in Tabellen oder als Defaultwerte in zumindest einer Speichereinheit der Programmsteuerung hinterlegt sind. Bei vernetzten Hausgeräten kann diese Speichereinheit auch außerhalb der Geschirrspülmaschine lokalisiert sein. Ferner sind in der Speichereinheit auch bestimmte Programmzustände abspeicherbar, deren Kombinationspaarungen z.B. nicht erwünscht sind hinterlegbar und diese können den Benutzer zu bestimmten Handlungen auffordern. Derartige nicht erwünschte Konstellationen ergeben sich z.B. im Programmabschnitt Vorspülen wenn eine erhöhte Schaumbildung und/oder deutliche pH-Wert-Schwankungen auftreten, bzw. eine vorgegebene Klarspülerkonzentration während aller Programmabschnitte unterschritten ist oder aber Klarspülerkonzentrationssprünge unabhängig von einer bestimmten Temperatur bzw. Temperaturverlauf auftreten. Der Benutzer kann entsprechend der aufgetretenen Fehlersituation z. B. aufgefordert werden das Einlegen eines Kombinationspräparates in die Dosierkombination vorzunehmen oder aber der Programmablauf wird abgebrochen bis benutzerabhängig eine erneute Inbetriebnahme des Geschirrspülers erfolgt oder aber das als fehlerhaft erkannte Messergebnis wird zumindest anzeigt.A suitable method of evaluation of the sensor measurement signals is z. B. the value or the change of certain parameters of the wash program such as turbidity, pH, foaming, concentration, water hardness u. a. individually as well as in suitable combinations at characteristic times of Spülprogrammablaufes, to determine their qualitative and quantitative appearance as well as their delay times with each other. For this purpose, at least individual parameter values can be determined within determinable time intervals or time intervals and subjected to an actual nominal value comparison, a difference value formation or a threshold value query or the changes can be made compared to preset values or values determined in the program sequence, all comparison values being shown in tables or as default values in at least one memory unit of the program control are stored. In networked household appliances, this storage unit can also be located outside the dishwasher. Furthermore, certain program states can also be stored in the memory unit, whose combination pairings are e.g. not desired are deposited and these can prompt the user to certain actions. Such undesirable constellations arise e.g. in the program section prewash if increased foaming and / or significant pH fluctuations occur, or a predetermined rinse aid concentration is exceeded during all program sections or rinse aid concentration jumps occur regardless of a specific temperature or temperature profile. The user can, for example, according to the occurred error situation. B. the loading of a combination preparation in the Dosierkombination make or the program flow is aborted until user-dependent re-commissioning of the dishwasher takes place or the detected as erroneous measurement result is at least indicating.
Im Programmabschnitt Vorspülen oder Reinigen kann vorgesehen sein, dass der Zeitpunkt der tatsächlichen Zudosierung des "3in1"-Kombinationspräparates zusätzlich überwacht wird, z. B. durch einen akustischen Sensor der Fall einer Tablette aus der Dosierkammer in den Spülbehälter detektiert wird. Andere Detektionsmöglichkeiten bieten optische Sensoren, die z. B. verstärkte Schaumbildung registrieren oder chemische Sensoren, die die Änderung des pH-Wertes der Spülflüssigkeit auswerten.In the program section prewash or cleaning can be provided that the time of actual addition of the "3in1" combination preparation is additionally monitored, z. B. is detected by an acoustic sensor, the case of a tablet from the metering chamber in the washing. Other Detection possibilities offer optical sensors, the z. B. register increased foaming or chemical sensors that evaluate the change in the pH of the rinsing fluid.
Mit weiterem Vorteil wird bei einem ggf. modifizierten Kombinationspräparat, in dem z. B. eine enzymatische Reinigersubstanz mit einer Wirksamkeitstemperaturgrenze von ca. 30 °C und eine Klarspülersubstanz mit einer Auflösetemperatur bei ca. 58 °C umfasst ist, bei gleichzeitig verkürzten vorgesehenen Programmabschnitten, und damit verkürzter Lösungsdauer, durch kurzzeitiges, ggf. auch wiederholtes Zuschalten und/oder gesteuerter oder geregelter Leistungsabgabe der Heizmittel in den Verfahrensabschnitten Vorspülen und/oder Zwischenspülen die Spülflüssigkeit vorzugsweise am Ende des jeweiligen Verfahrensabschnittes aufgeheizt, so dass für die folgenden Verfahrensabschnitte Reinigen bzw. Klarspülen, die mit heißer Spülflüssigkeit betrieben werden, die jeweilige chemische Substanz ihre vollständige Wirksamkeit besser und länger entfalten kann. Durch das Vorheizen bzw. verstärkte Aufheizen der Spülflüssigkeit am Ende des vorangehenden Spülprogrammabschnittes ist das Auflösen und damit die Wirksamkeit des Reinigers oder Klarspülers für die Dauer eines jeden Programmabschnittes verbessert. Die dabei zugeführte Energie ist der einer Aktivierungsenergie vergleichbar. Bei einer vorgesehenen Temperatursteuerung oder Temperaturregelung können Auflösungsdauer, Konzentration, Einwirkzeit, Zeitpunkt der Freisetzung einer chemischen Substanz des "3in1"-Kombinationspräparates optimiert werden.With further advantage is in an optionally modified combination preparation in which z. B. an enzymatic cleaner substance having an efficacy temperature limit of about 30 ° C and a rinse aid substance with a dissolution temperature at about 58 ° C is included, with shortened scheduled program sections, and thus shortened solution duration, by short-term, possibly repeated and / or or controlled or regulated power output of the heating means in the pre-washing and / or intermediate rinsing the rinse liquid preferably heated at the end of the respective process section, so that for the following process sections cleaning or rinsing, which are operated with hot rinse liquid, the respective chemical substance their full effectiveness can develop better and longer. By preheating or intensified heating of the rinsing liquid at the end of the preceding rinsing program section, the dissolution and thus the effectiveness of the cleaner or rinse aid for the duration of each program section is improved. The energy supplied is comparable to that of an activation energy. With an intended temperature control or temperature control, the dissolution time, concentration, exposure time, time of release of a chemical substance of the "3in1" combination preparation can be optimized.
Von besonderem Vorteil ist dabei, wenn benutzerabhängig das tatsächlich verwendete "3in1"-Kombinationspräparat der Programmsteuerung als Parameter vorgegeben wird, z. B. durch Eingabe über eine Bilderfassung, die z. B. den Barcode eines "3in1"-Kombinationspräparates erkennt oder im Programmspeicher hinterlegte im Handel erwerbbare "3in1"-Kombinationspräparate ausgewählt werden oder die Verwendung eines bestimmten Kombinationspräparates durch den Benutzer in sonstiger Weise eingegeben werden kann, wobei die benutzerabhängig vorgegebene Information über die Verwendung eines bestimmten "3in1"-Kombinationspräparates entweder bis zu einer sich ändernden Eingabe Informationen gespeichert werden oder aber zu Beginn eines jeden oder definiert vorgegebenen Zeitpunktes erneut abgefragt wird.It is particularly advantageous if, depending on the user, the actually used "3in1" combination preparation of the program control is specified as a parameter, eg. B. by input via an image capture, the z. B. recognizes the barcode of a "3in1" combination preparation or stored in the program store commercially available "3in1" combination preparations can be selected or the use of a specific combination preparation can be entered by the user in any other way, the user-dependent predetermined information on the use of a certain "3in1" combination preparations are either stored up to a changing input information or retrieved at the beginning of each or a defined predetermined time.
Mit weiterem Vorteil kann bei Abfrage bzw. Auswertung einer Information über die Art und Darreichungsform der zugeführten Reinigungs-, Klarspül- und ggf. Enthärtungssubstanzen ein eindeutig nicht als "3in1"-Kombinationspräparat identifiziertes Produkt eine fälschlicherweise durch den Benutzer ausgewählte "3in1"-Funktion abschalten bzw. bei Auswahl eines "3in1"-Programmes eine Fehlermeldung ausgegeben werden.With further advantage, in the case of interrogation or evaluation of information about the type and dosage form of the supplied cleaning, rinsing and possibly softening substances, a product unequivocally not identified as a "3in1" combination preparation can deactivate a "3in1" function erroneously selected by the user or when selecting a "3in1" program, an error message is output.
Es ist ferner von Vorteil, dass bei eingeschalteter "3in1"-Funktion bzw. bei Auswahl eines "3in1"-Spülprogrammes die Anzeige für Zustände des Spülprogrammes, die bei herkömmlichen Spülprogrammen mit Einzeldosierung der Substanzen eingeschaltet sind, abgeschaltet oder ausgeblendet werden, so z. B. die Abschaltung einer Anzeige-LED zum Zeitpunkt des Regeneriervorganges oder eine Anzeige-LED, die zur Auffüllung von Klarspüler auffordert.It is also advantageous that when the "3in1" function is switched on or when a "3in1" rinsing program is selected, the display for states of the rinsing program which are switched on in conventional rinsing programs with single dosing of the substances are switched off or faded out, for example. As the shutdown of a display LED at the time of recovery or a display LED, which asks for replenishment of rinse aid.
Wird durch den Benutzer der Geschirrspülmaschine nach dem Einstellen verschmutzten Spülgutes in die Geschirrspülmaschine ein Spülprogramm ausgewählt, ein Kombinationspräparat der Geschirrspülmaschine zugegebenen und durch ein optional zugeschaltetes Auswahlmittel die Verwendung eines Kombinationspräparates angezeigt, so sieht die Programmablaufsteuerung unter Berücksichtigung der Zusatzfunktion vor, dass sich der Programmablauf des ausgewählten Spülprogrammes ändert und in seiner gesamten Gestaltung an die Verwendung eines Kombinationspräparates angepasst wird. Dabei werden in Abhängigkeit des ausgewählten Spülprogrammes einzelne oder mehrere Parameter der verschiedenen Spülprogrammabschnitte Vorspülen, Reinigen, Zwischenspülen, Klarspülen, in nachfolgend beschriebener Weise selbsttätig im wesentlichen abhängig von der Auswertung vorgegebener Sensormessungen angepasst oder in fest vorgegebener Weise verändert. Die dabei in den Verfahrensansprüchen aufgezeigten Schritte stellen hinsichtlich ihrer Abfolge kein zwangsläufig Erfordernis für den Spülprogrammablauf dar, sondern können gezielt z.B. in Abhängigkeit der Verwendung eines bestimmten Kombinationspräparates oder Typus des Kombinationspräparates ausgewählt, wiederholt und/oder nacheinander geschaltet oder von anderen, an sich bekannten Programmschritten gefolgt werden.If a washing program is selected by the user of the dishwasher after setting soiled items in the dishwasher, adding a combination preparation to the dishwasher and the use of a combination preparation indicated by an optionally switched selection means, the program sequence control, taking into account the additional function, provides that the program sequence of selected rinse program changes and is adapted in its entire design to the use of a combination preparation. Depending on the selected wash program, individual or several parameters of the various wash program sections pre-wash, clean, intermediate wash, rinse, are automatically adjusted in the manner described below, depending on the evaluation of predetermined sensor measurements, or changed in a predefined manner. The steps indicated in the method claims in this case do not necessarily represent a requirement for the washing program sequence with regard to their sequence, but can specifically be determined, e.g. be selected depending on the use of a particular combination preparation or type of combination preparation, repeated and / or sequentially switched or followed by other program steps known per se.
Bei der Verwendung einer Dosierkombination mit üblicherweise getrennter Vorratskammern für die Reiniger- und Klarspülersubstanz wird bei Verwendung eines "3in1"-Kombinationspräparates die Funktion der Klarspüler- und ggf. der Reinigerdosierung im ausgewählten Spülprogramm ausgeblendet. In einer alternativen Ausgestaltung ist es möglich bei der z. B. sensorabhängigen Bestimmung der Konzentration des Klarspülers diesen in erforderlichen Mengen nachzudosieren, dies gleicht ggf. Verdünnungsverluste der vorangehenden Spülprogrammabschnitte aus. Sofern während des ausgewählten Spülprogrammes weitere Öffnungszeitpunkte für die Dosiereinrichtung zur Freigabe verschiedenster Substanzen vorgesehen sind, werden auch diese gesperrt oder der Zeitpunkt der Zudosierung einer bestimmten Substanz verschoben und/oder in der Mengendosierung verändert.When using a dosing combination with usually separate storage chambers for the detergent and rinse aid substance, the function of the rinse aid and possibly the detergent dosing in the selected rinse program is hidden when using a "3in1" combination preparation. In an alternative embodiment, it is possible for the z. B. sensor-dependent determination of the concentration of the rinse aid to meter these in required amounts, this compensates if necessary, dilution losses of the previous rinse program sections. If, during the selected wash program, further opening times for the metering device are provided for releasing a wide variety of substances, these too are blocked or the time of metering in a particular substance is shifted and / or changed in the metering dosage.
Ist dem Kombinationspräparat neben der Reinigungssubstanz und der Klarspülsubstanz auch eine Enthärtungssubstanz zugesetzt, die das Enthärten in bekannter Weise in der Geschirrspülmaschine durch eine vorgesehene Enthärtungsvorrichtung unnötig machen soll, dann ist auch das bekannterweise in einer Geschirrspülmaschine durchzuführende Regenerieren des Enthärters mit gesättigter Salzlösungen (Sole) nicht notwendig, daher wird im Programmablauf die Regenerierfunktion, d. h. das Zusetzen eines definierten Solevolumens zur Enthärtungsvorrichtung, das ansonsten zu einem definierten Zeitpunkt des Programmablaufes vorgesehen ist, ausgeblendet. Erfindungsgemäß wird bei einem vorgesehenen Härtesensor, der die Wasserhärte der Spülflüssigkeit bestimmen kann, die tatsächlich in der Geschirrspülmaschine vorhandene Wasserhärte infolge des Enthärtens mit der Enthärtungssubstanz des Kombinationspräparates erforderlichenfalls überwacht und ggf. die Regenerierfunktion des Enthärters zugeschaltet, so dass eine Teilenthärtung des Wassers über die Enthärtervorrichtung vorgenommen wird. In Hartwassergebieten reicht erfahrungsgemäß das Enthärtungsvermögen der Enthärtersubstanzen eines "3in1"-Kombinationspräparates nicht aus. Deshalb ist es von besonderem Vorteil, wenn die Information über den Härtegrad des tatsächlich verwendeten Wassers der Zuleitung in die Gestaltung des Programmablaufes einfließt. Der Härtegrad des Wassers kann beispielsweise vom Benutzer über eine speziell vorgesehene Eingabefunktion, z. B. in der Bedienblende, eingegeben und gespeichert werden bzw. auch an einer Verschneideeinrichtung eingestellt werden, wobei entsprechende Mittel den Wert der Wasserhärteeinstellung an die Programmablaufsteuerung weiterleiten und bei eingeschalteter "3in1"-Funktion bzw. Auswahl eines "3in1"-Spülprogrammes das Zuschalten der Regenerierfunktion und/oder zumindest das Verschneiden von hartem mit weichem Wasser zumindest zu einem vorgegebenen Zeitpunkt ermöglichen.If, in addition to the cleaning substance and the rinse aid substance, a softening substance is added to the combination preparation which is to make it unnecessary to soften in a known manner in the dishwasher by means of an intended softening device, then this is also known to be one Dishwasher to be performed regenerating the softener with saturated salt solutions (brine) is not necessary, therefore, in the program flow the Regenerierfunktion, ie the addition of a defined brine volume to the softening device, which is otherwise provided at a defined time of the program sequence hidden. According to the invention, the water hardness actually present in the dishwasher, if necessary, monitored due to softening with the softening substance of the combination preparation and possibly the Regenerierfunktion the softener switched so that a partial softening of the water through the softening device at a designated hardness sensor that can determine the water hardness of the rinse is made. Experience has shown that in hard water areas the softening capacity of the softening substances of a "3in1" combination preparation is insufficient. Therefore, it is particularly advantageous if the information about the degree of hardness of the actually used water of the supply line flows into the design of the program sequence. The degree of hardness of the water, for example, by the user via a specially provided input function, eg. B. in the control panel, entered and stored or be set to a blending, with appropriate means forward the value of the water hardness setting to the program flow control and switched on "3in1" function or selection of a "3in1" purging the connection of Regenerierfunktion and / or at least allow the blending of hard and soft water at least at a given time.
Es ist vorgesehen, den bisherigen Wasserzulauf weiter über die Enthärtervorrichtung unabhängig von deren Enthärterkapazität, die mit zunehmender Zahl der Spülflüssigkeitswechsel in Abhängigkeit des Härtegrades des zugeführten Wassers erschöpft ist, zu führen. Alle anderen Alternativen des Wasserzulaufes sind zwar theoretisch möglich, jedoch nur dann zweckmäßig, wenn standardmäßig nur noch Kombinationspräparate mit einer Enthärtersubstanz erhältlich sind. Das ggf. im Vorratsbehälter der Geschirrspülmaschine definiert vorgehaltene Wasservolumen für die Regenerierfunktion kann insbesondere in Weichwassergebieten alternativ als definiertes Volumen ganz oder teilweise in den flüssigkeitsführenden Programmabschnitten zur Bemessung eines vorbestimmten Flüssigkeitsvolumens verwendet werden.It is envisaged to continue the previous water supply through the softening device regardless of their softening capacity, which is depleted with increasing number of rinsing fluid change depending on the degree of hardness of the water supplied. All other alternatives of the water supply are theoretically possible, but only useful if, by default, only combination preparations with a softening agent are available. The water volume for the regeneration function, optionally defined in the storage container of the dishwasher, can be used, in particular in soft water areas, alternatively as a defined volume wholly or partly in the liquid-carrying program sections for dimensioning a predetermined liquid volume.
Wird durch einen Sensor während'eines einleitenden Vorspülens die Verwendung eines Kombinationspräparates erkannt bzw. die Verwendung desselben durch eingeschaltete Zusatzfunktion angezeigt, so kann die Dauer des zunächst vorgesehenen Programmabschnittes Vorspülen verkürzt werden um zu verhindern, dass sich die umfassten Reiniger- und Klarspülerwirkstoffe zu früh auflösen und in den Abschnitten Reinigen bzw. Klarspülen in zu geringer Konzentration vorliegen. Ist andererseits ein Spülprogramm ausgewählt, das zwei oder mehrere Vorspülabschnitte mit jeweils vollständigem Wasserwechsel vorsieht, so wird durch Weglassen zumindest eines Vorspülens bzw. die Reduzierung auf einen Programmabschnitt Vorspülen hierdurch auch ohne die Detektion eines Kombinationspräparates bereits prophylaktisch verhindert, dass sich ein fälschlicherweise in den Geschirrspülmaschine statt in die Dosierkombination eingelegtes Kombinationspräparate zu früh auflöst.If the use of a combination preparation is detected by a sensor during an initial pre-rinsing or the use thereof is indicated by the auxiliary function switched on, the duration of the initially provided program section pre-rinsing can be shortened in order to prevent the encompassed rinse aid and rinse aid active substances from dissolving too early and in the cleaning or rinsing sections are in too low a concentration. If, on the other hand, a rinsing program is selected which provides for two or more pre-rinsing sections, each with complete water change, then by omitting at least one pre-rinsing or reducing to a pre-rinsing section of the program, this already prevents prophylaxis, even without the detection of a combination preparation, from being incorrectly introduced into the dishwasher instead of dissolved in the dosing combination combined preparations dissolves too early.
Wird wie oben geschildert der Verfahrensabschnitt Vorspülen verkürzt oder ganz ausgelassen, so verringert sich hierdurch die Zeit des Beaufschlagens des Spülgutes mit Wasser, der Anlösevorgang von starken Verschmutzungen, die möglicherweise schon lang am Spülgut haften, wird hierdurch verkürzt oder ganz aufgehoben. Das ist in manchen Verschmutzungsfällen einem guten Reinigungsergebnis nicht förderlich. Deshalb wird in solchen Fällen der Verfahrensabschnitt Reinigen vorzugsweise um die Dauer des Verfahrensabschnittes verlängert, um die der Verfahrensabschnitt Vorspülen verkürzt wurde. So wird das Anlösen der Schmutzpartikel zumindest teilweise in den Verfahrensabschnitt Reinigen verschoben.If, as described above, the pre-rinsing process section is shortened or completely omitted, this reduces the time of loading the ware with water, the process of dissolving heavy soiling, which may have long adhered to the ware, is thereby shortened or completely eliminated. This is not conducive to good cleaning results in some cases of contamination. Therefore, in such cases, the process section cleaning is preferably extended by the duration of the process section by which the pre-rinse process section has been shortened. Thus, the dissolution of the dirt particles is at least partially moved into the cleaning procedure.
Besonders bevorzugt wird die Zahl der Zwischenspülabschnitte zwischen den Programmabschnitten Reinigen und Klarspülen auf einen Zwischenspülabschnitt reduziert, der im Wesentlichen die Aufgabe hat, vereinzelt hängen gebliebene Schmutzteilchen und chemische Rückstände des Reinigens zu beseitigen. Mit weiterem Vorteil kann das Zwischenspülen bei verringertem maximalen Spülflüssigkeitsvolumen gegenüber dem maximal vorgesehenen Spülflüssigkeitsvolumen des Programmabschnittes Reinigen betrieben werden, so dass die Konzentration des gelösten Klarspülers höher ist als bei gleich großem Spülflüssigkeitsvolumen wie im Reinigen. Wird während des Programmabschnittes Reinigen die Spülflüssigkeit mehrfach verdünnt und/oder ist durch eine entsprechende Trübungsmessung ein geringer Verschmutzungsgrad der Spülflüssigkeit erkannt worden, so kann auf den Zwischenspülabschnitt ggf. vollständig verzichtet werden.Particularly preferably, the number of intermediate rinsing sections between the cleaning and rinsing program sections is reduced to an intermediate rinsing section, which essentially has the task of eliminating occasionally trapped dirt particles and chemical residues of the cleaning. With further advantage, the intermediate rinsing can be operated with a reduced maximum rinsing liquid volume compared to the maximum intended rinsing liquid volume of the program section cleaning, so that the concentration of the dissolved rinse aid is higher than with the same size rinsing liquid volume as in cleaning. If during the program section cleaning the rinsing liquid is diluted several times and / or a low degree of contamination of the rinsing liquid has been detected by a corresponding turbidity measurement, the intermediate rinsing section may possibly be completely dispensed with.
Im Verfahrensabschnitt Zwischenspülen, der mit lauwarmer Spülflüssigkeit betrieben wird und demzufolge kein aktives Aufheizen durch Zuschalten vorgesehener Heizelemente vorsieht, wird die während der Verfahrensabschnitte, die mit heißer Spülflüssigkeit betrieben werden, eingespeiste Energie entzogen. Um den Verfahrensablauf energetisch günstig und wie oben beschrieben auch Wasser sparend und damit die Konzentration des Klarspülers erhöhend im Verfahrensabschnitt Zwischenspülen zu gestalten, kann vorgesehen sein, durch wiederholtes Ein- und Ausschalten der Umwälzpumpe mit unterschiedlich bestimmbarer und/oder vorgebbarer Dauer des Ein- und Ausschaltzustandes der Umwälzpumpe die Spülflüssigkeit in der Art eines Impulsspülens auf das Spülgut einzubringen. Beim Ausschalten der Umwälzpumpe ist das Umwälzen der Spülflüssigkeit und damit das Beaufschlagen des Spülgutes mit Spülflüssigkeit unterbrochen. Diese Art des Impulsspülens ist kurz mit einer Abfolge Bespritzen, Pause, Bespritzen, Pause, Bespritzen, Pause, usw. beschrieben.In the intermediate flushing process section, which is operated with lukewarm rinsing liquid and therefore does not provide active heating by switching on provided heating elements, the energy fed in during the process sections which are operated with hot rinsing liquid is removed. In order to make the procedure energetically favorable and as described above also water-saving and thus increasing the concentration of the rinse aid in the process section intermediate rinsing, can be provided by repeated switching on and off the circulation pump with different determinable and / or predefinable duration of the on and off state the circulation pump to bring the rinsing liquid in the manner of a pulse rinse on the dishes. At the Turning off the circulation pump, the circulation of the rinsing liquid and thus the application of the ware is interrupted with rinsing liquid. This type of pulse purging is briefly described with a sequence of spraying, pausing, splattering, pausing, splashing, pausing, etc.
Am Ende zumindest eines Verfahrensabschnittes wie z. B. dem Zwischenspülen kann in Abhängigkeit der Messung der Trübung und/oder des Gehaltes an Klarspüler in der Spülflüssigkeit ein Verdünnungsschritt vorgesehen sein. Der Verdünnungsschritt bewirkt, dass ein Teilvolumen der Spülflüssigkeit, welche während des Zwischenspülens benutzt wurde, in dem anschließenden Verfahrensabschnitt Klarspülen weiter verwendet wird und mit frischer Spülflüssigkeit, die zugeführt wird, vermischt ist. Infolge des Verdünnungsschrittes wird der Verlust insbesondere an Klarspüler gegenüber einem vollständigen Abpumpen und Auffüllen von Spülflüssigkeit verringert. Eben aus diesem Grund kann auch unabhängig von der Messung der Trübung der Spülflüssigkeit zwangsläufig ein Verdünnungsschritt anstelle eines vollständigen Abpumpens der Spülflüssigkeit z. B. am Ende eines Spülprogrammabschnittes vorgesehen sein.At the end of at least one procedure section such. B. the intermediate rinse may be provided in dependence of the measurement of turbidity and / or the content of rinse aid in the rinsing liquid, a dilution step. The dilution step causes a partial volume of the rinsing liquid, which was used during the intermediate rinsing, to continue to be used in the subsequent rinsing process section and to be mixed with fresh rinsing liquid to be supplied. As a result of the dilution step, the loss in particular of rinse aid against a complete pumping and filling of rinsing liquid is reduced. Precisely for this reason, irrespective of the measurement of the turbidity of the rinsing liquid inevitably a dilution step instead of a complete pumping out of the rinsing liquid z. B. be provided at the end of a rinse program section.
Als weiterer oder alternativer Schritt wird bevorzugt die Temperatur in den dem Programmabschnitt Klarspülen vorgelagerten Verfahrensabschnitten, vorzugsweise im Verfahrensabschnitt Reinigen, auf eine Temperatur unterhalb der Auflösungstemperatur des Klarspülers, vorzugsweise unterhalb von 58 °C, reduziert. Damit wird bei z. B. einem ausgewählten Intensivprogramm, welches üblicherweise den Reinigungsabschnitt mit Temperaturen zwischen 58 und 70 °C betreibt, verhindert, dass bei Verwendung eines Kombinationspräparates mit temperaturabhängiger Freigabe der Klarspülersubstanz diese sich ggf. schon hier auflöst und demzufolge im Programmabschnitt Klarspülen in zu geringer Konzentration vorliegt.As a further or alternative step, the temperature in the process sections preceding the program section rinsing, preferably in the process section cleaning, is preferably reduced to a temperature below the dissolution temperature of the rinse aid, preferably below 58 ° C. This is at z. B. a selected intensive program, which usually operates the cleaning section with temperatures between 58 and 70 ° C, prevents that when using a combination preparation with temperature-dependent release of the rinse aid substance this possibly already dissolves here and therefore present in the program section rinse in too low a concentration.
Im Programmabschnitt Klarspülen wird das Spülgut auf eine Temperatur von mindestens 58 °C für den anschließenden Programmabschnitt Trocknen aufgeheizt, hierdurch wird auch das temperaturabhängige und ggf. pH-Wert-abhängige Auflösen des Klarspülers ermöglicht.In the program section rinsing the items to be washed is heated to a temperature of at least 58 ° C for the subsequent program section drying, thereby also the temperature-dependent and possibly pH-dependent dissolution of the rinse aid is possible.
Mit Vorteil ist die Temperaturführung der Spülflüssigkeit während eines ausgewählten Spülverfahrens, das auf die Verwendung von Kombinationspräparaten selbsttätig, wie vorstehend erwähnt, angepasst wurde, zum einen durch die Auflösetemperaturen der einzelnen chemischen Substanzen bestimmt. Zum anderen wird unter energetischen Gesichtspunkten während des Vorspülens, sofern es durchgeführt wird, die Spülflüssigkeit nicht durch Zuschalten vorgesehener Heizmittel aufgeheizt, so dass die Spülflüssigkeit im Wesentlichen von der Wasserzulauftemperatur abhängig ist. Während des Reinigens und Klarspülens wird die Spülflüssigkeit infolge Einschaltens vorgesehener Heizmittel aktiv aufgeheizt und im Programmabschnitt Zwischenspülen ohne Zuschalten dieser Heizmittel passiv, d. h. durch Entnahme von Energie aus den Wärmekapazitäten des Geschirrspülers, deutlich auf eine Temperatur unterhalb der Auflösungstemperatur eines temperaturabhängigen Klarspülers aufgeheizt.Advantageously, the temperature control of the rinsing liquid during a selected rinsing process, which has been adapted to the use of combination preparations automatically, as mentioned above, determined on the one hand by the dissolution temperatures of the individual chemical substances. On the other hand, from an energetic point of view, during the pre-rinsing, if it is carried out, the rinsing liquid is not heated by switching on intended heating means, so that the rinsing liquid essentially depends on the water inlet temperature. During rinsing and rinsing, the rinsing liquid is actively heated as a result of switching on the heating means provided and passive in the intermediate rinsing program section without connecting these heating means, ie. H. by removing energy from the heat capacity of the dishwasher, heated significantly to a temperature below the dissolution temperature of a temperature-dependent rinse aid.
Ohne die Erfindung zu beschränken ist es möglich, Bestandteile des Spülprogrammes bei ausgewählter "3in1"-Funktion ganz oder teilweise nach einem definiert vorgegebenen Programm ablaufen zu lassen bzw. Erkennen und Auswertung von bestimmten Parametern, z. B. durch Sensoren, in geeigneter Weise an die Ist-Situation in Bezug auf eine vorgegebene Soll-Situation ganz oder teilweise anzupassen.Without restricting the invention, it is possible, parts of the wash program with selected "3in1" function run completely or partially according to a defined predetermined program or detection and evaluation of certain parameters, eg. B. by sensors, in a suitable manner to the actual situation with respect to a predetermined desired situation completely or partially adapt.
Das Zuschalten der "3in1"-Funktion bzw. die Auswahl eines "3in1"-Spülprogrammes kann ferner auch bei vernetzten Haushaltgeräten, die ortsunabhängig von einem nicht im Geschirrspüler lokalisierten Zentralrechner betrieben werden, erforderlichenfalls zugeschaltet werden.The connection of the "3in1" function or the selection of a "3in1" purging program can also be switched on, if necessary, in the case of networked household appliances which are operated independently of location by a central computer not located in the dishwasher.
Neben den bereits bekannten auswählbaren Spülprogrammen Normalprogramm, Intensivprogramm, Ökoprogramm, Kurzprogramm, kann auch ein spezielles "3in1"-Spülprogramm vorgesehen sein, das an die Verwendung von Kombinationspräparaten, insbesondere solchen, die Reiniger, Enthärter und Klarspüler gleichzeitig enthalten, von vornherein angepasst ist. Dieses "3in1"-Spülprogramm wird durch den Benutzer der Geschirrspülmaschine direkt ausgewählt und ist durch die im Folgenden genannten wesentlichen Verfahrensschritte gekennzeichnet, die dabei genannte, jedoch nicht zwangsläufige Abfolge der Verfahrensschritte stellt dabei einen möglichen Spülprogrammablauf ohne den abschließenden Programmabschnitt Trocknen dar:In addition to the well-known selectable programs normal program, intensive program, eco program, short program, a special "3in1" flushing program can be provided, which is adapted from the outset to the use of combination preparations, especially those containing cleaners, softeners and rinse aid at the same time. This "3in1" purging program is selected directly by the user of the dishwasher and is characterized by the following essential process steps, the case mentioned but not necessarily sequence of process steps represents a possible Spülprogrammablauf without the final program section drying:
Verändern oder Abschalten der Enthärterfunktion der Regeneriereinrichtung und/oder Verändern oder Abschalten der Öffnung spezieller Bevorratungskammern der Dosiervorrichtung für insbesondere neben dem Kombinationspräparat weiterhin einzeln bevorrateter chemischer Substanzen (Reiniger, Klarspüler) und/oder Verändern der Zudosierungsmenge der bevorrateten chemischen Substanzen.Changing or switching off the softening function of the regenerating device and / or changing or switching off the opening of special storage chambers of the metering device for in addition to the combined preparation still individually stored chemical substances (detergent, rinse aid) and / or changing the Zudosierungsmenge the stored chemical substances.
Abschalten korrespondierender Anzeigeelemente zu Funktionen, die während des Programmablaufes zumindest durch die Programmablaufsteuerung von vornherein, dass heißt voreingestellt abgeschaltet werden, vorzugsweise Abschalten der Anzeige Regenerierung bei abgeschalteter Regenerierfunktion durch die Regeneriereinrichtung und/oder Abschalten der Anzeige Klarspüler nachfüllen bei zumindest abgeschalteter automatischer Zudosierung des Klarspülers.Turn off corresponding display elements to functions that are switched off during the program, at least by the program control from the outset, that is preset, preferably switching off the display regeneration with switched off regeneration by the regenerator and / or turning off the display refill rinse at least disabled automatic dosing of the rinse aid.
Das Vorspülen erfolgt mit kaltem Wasser, das also im Wesentlichen von der Wasserzuleitungstemperatur abhängig ist, für eine äußerst kurze Dauer von 2 bis 5 min., vorzugsweise 2 bis 3 min. In dieser Zeit können hauptsächlich frische Verschmutzungen abgelöst und länger anhaftende Verschmutzungen angeweicht werden. In Abhängigkeit einer optionalen Trübungsmessung der Flüssigkeit können bei starker Verschmutzung ein oder mehrere Verdünnungsschritte der Spülflüssigkeit vorgesehen sein, wobei ein Verdünnungsschritt aufgrund der Kürze des Vorspülens, vorzugsweise am Ende des Vorspülens, vorgesehen ist. Findet am Ende des Vorspülens kein Verdünnungsschritt statt, so wird die Spülflüssigkeit vor dem folgenden Programmabschnitt vollständig gewechselt.The pre-rinse is done with cold water, which is thus essentially dependent on the water supply temperature, for an extremely short period of 2 to 5 min., Preferably 2 to 3 min. During this time, mainly fresh soiling can be detached and softened dirt can be softened. Depending on an optional turbidity measurement the liquid can be provided with heavy contamination one or more dilution steps of the rinsing liquid, wherein a dilution step due to the brevity of the pre-rinsing, preferably at the end of the pre-rinsing is provided. If no dilution step takes place at the end of the pre-rinse, the rinse liquid is completely changed before the next program section.
Die dabei frisch zugeführte Spülflüssigkeit, die auch verdünnt und damit in einem gewissen Grad verunreinigt sein kann, wird nun im Verfahrensabschnitt Reinigen auf eine Temperatur, die unterhalb der Auflösetemperatur des Klarspülers, vorzugsweise zwischen 40 und 57 °C, liegt, aufgeheizt.The freshly supplied rinsing liquid, which may also be diluted and thus contaminated to a certain extent, is now heated in the cleaning process section to a temperature which is below the dissolution temperature of the rinse aid, preferably between 40 and 57 ° C.
Das Kombinationspräparat wird durch die Dosiervorrichtung vorzugsweise innerhalb des ersten Drittels des Programmabschnittes Reinigen dem Spülbehälter zugeführt, sofern das Kombinationspräparat nicht durch den Benutzer vor dem Starten des Spül-Spülprogrammes in den Spülbehälter, z. B. in den Besteckkorb, eingelegt wurde.The combination preparation is preferably supplied to the rinsing container by the dosing device within the first third of the program section cleaning, provided that the combination preparation is not by the user before starting the rinsing-rinsing program in the washing, z. B. in the cutlery basket was inserted.
Bei der o. g. Temperatur wird die Spülflüssigkeit im Spülbehälter während des Reinigens ca. 10 bis 30 Minuten umgewälzt und am Ende des Verfahrensabschnittes Reinigen vollständig abgepumpt oder verdünnt. Diese Entscheidung kann von einer optional durchgeführten Trübungsmessung der Spülflüssigkeit abhängig gemacht werden.In the o. G. Temperature, the rinsing liquid is circulated in the washing during cleaning about 10 to 30 minutes and completely pumped or diluted at the end of the cleaning process section. This decision can be made dependent on an optional turbidity measurement of the rinsing liquid.
Wird zumindest eine Trübungsmessung der Spülflüssigkeit durchgeführt, so ist ein Durchführen mehrerer Verdünnungsschritte in Abhängigkeit des Verschmutzungsgrades und/oder der Konzentration einzelner Bestandteile des Kombinationspräparates optional ausführbar. Auf den Verfahrensabschnitt Reinigen folgt ein Verfahrensabschnitt Zwischenspülen, bei dem die nunmehr vorhandene frische oder verdünnte Spülflüssigkeit passiv, d. h. ausschließlich durch Energieentnahme der Wärmekapazitäten des Geschirrspülers aufgeheizt wird, so dass diese während ihres Umwälzens noch vorhandene letzte Schmutzreste und chemische Rückstände des Verfahrensabschnittes Reinigen entfernt. Das Umwälzen der Spülflüssigkeit findet im Verfahrensabschnitt Zwischenspülen für eine Dauer von ca. 2 bis 10 Minuten statt. Alternativ kann das Zwischenspülen auch als Impulsspülen bei verringertem maximalen Spülflüssigkeitsvolumen bzgl. des maximalen Spülflüssigkeitsvolumen des Reinigens betrieben werden .If at least one turbidity measurement of the rinsing liquid is carried out, it is optionally possible to carry out a plurality of dilution steps as a function of the degree of soiling and / or the concentration of individual constituents of the combined preparation. The process section cleaning is followed by a process section intermediate rinsing in which the fresh or diluted rinsing liquid now present is passively, i. H. is heated exclusively by energy removal of the heat capacity of the dishwasher, so that it removes during their circulation still existing residual debris and chemical residues of the process section cleaning. The circulation of the rinsing liquid takes place in the intermediate rinsing section for a period of about 2 to 10 minutes. Alternatively, the intermediate rinsing can also be operated as pulse rinsing with a reduced maximum rinsing liquid volume with respect to the maximum rinsing liquid volume of the cleaning.
Der Verfahrensabschnitt Zwischenspülen wird mit einer vollständigen oder teilweisen Entleerung beendet.The intermediate flushing stage ends with a complete or partial drainage.
Im Verfahrensabschnitt Klarspülen wird dem Spülbehälter ein definiertes Spülflüssigkeitsvolumen zugeführt. Dieses kann von vorne herein fest bemessen sein und/oder variabel in Abhängigkeit verschiedenster Parameter eingestellt werden. Eine abhängige Größe ist dabei die Konzentration des dabei tatsächlich in der Spülflüssigkeit vorhandenen Klarspülers, da diese unmittelbaren Einfluss auf das Klarspülergebnis und somit auf das anschließend erzielbare Trocknungsergebnis des Spülgutes nimmt. So wird im Falle einer geringen Konzentration des Klarspülers am Anfang des Programmabschnittes Klarspülen die Spülflüssigkeit so gering wie möglich, ggf. jedoch in Abhängigkeit des Trübungsgrades der Spülflüssigkeit, zugeführt werden. Ist anderenfalls die Konzentration des Klarspülers zu Beginn des Programmabschnittes Klarspülen überdurchschnittlich oder ausreichend hoch, so kann die Konzentration des Klarspülers durch Zuführung eines definiert einstellbaren Spülflüssigkeitsvolumens auf eine vorbestimmte Konzentration eingestellt werden. Die Spülflüssigkeit mit bereits aufgelöstem Klarspüler, wie auch die mit noch aufzulösendem Klarspüler, wird nunmehr vorzugsweise auf eine Auflösetemperatur oberhalb der Auflösetemperatur eines ph-Wert- und/oder temperaturabhängigen sich auflösenden Klarspülers aufgeheizt. Diese Auflösetemperatur liegt derzeit oberhalb von 58 °C (für das "3in1"-Kombinationspräparat Calgonit Powerballs®). Für eine Dauer von 2 bis 15 Minuten, jedoch ebenfalls zumindest bis zum Erreichen einer vorgegebenen Temperatur von derzeit vorzugsweise 65 bis 70 °C, wird die Spülflüssigkeit aufgeheizt und umgewälzt. Am Ende des Programmabschnittes Klarspülen wird die Spülflüssigkeit soweit als möglich durch Abpumpen aus dem Spülbehälter entfernt.In the rinsing process section, a defined rinsing liquid volume is supplied to the rinsing container. This can be fixed from the outset and / or set variably in dependence of various parameters. A dependent variable is the concentration of the rinse aid actually present in the rinse liquid, since this has an immediate effect on the rinse aid result and thus on the subsequently achievable drying result of the ware. Thus, in the case of a low concentration of the rinse aid at the beginning of the program section rinsing the rinsing liquid as low as possible, but possibly depending on the degree of turbidity of the rinsing liquid, are supplied. If, otherwise, the concentration of the rinse aid at the beginning of the program section rinsing is above average or sufficiently high, the concentration of the rinse aid can be adjusted to a predetermined concentration by supplying a defined rinse liquid volume. The rinsing liquid with rinse aid already dissolved, as well as the rinse aid still to be dissolved, is now preferably heated to a dissolution temperature above the dissolution temperature of a rinse aid dissolving in pH and / or temperature. This dissolution temperature is currently above 58 ° C (for the "3in1" combination preparation Calgonit Powerballs®). For a period of 2 to 15 minutes, but also at least until reaching a predetermined temperature of currently preferably 65 to 70 ° C, the rinsing liquid is heated and circulated. At the end of the rinsing program section, the rinsing liquid is removed as far as possible by pumping out of the rinsing container.
An dem Spülgut, der Spülbehälterdecke, den Spülbehälterwänden verbleibende Restflüssigkeit und Wasserdampf wird im, auf den Programmabschnitt Klarspülen folgenden, Programmabschnitt Trocknen entfernt. Die Trocknung wird dabei vorzugsweise als Kondensationstrocknung durchgeführt. Während der Kondensationstrocknung wird, sofern vorhanden, vorzugsweise im ersten Drittel dieses Programmabschnittes zumindest ein Umluftgebläse eingeschaltet.On the items to be washed, the Spülbehälterdecke, the Spülbehälterwänden remaining residual liquid and water vapor is removed in, following the program section rinse, program section drying. The drying is preferably carried out as condensation drying. During the condensation drying, if present, preferably at least one circulating air blower is switched on in the first third of this program section.
Das Zwischenspülen während der flüssigkeitsführenden Verfahrensabschnitte kann bevorzugt als Impulsspülen ausgestaltet sein, d. h. dass während des Verfahrensabschnittes Zwischenspülen die Umwälzpumpe wiederholt für eine vorgebbare oder bestimmbare Dauer ein- und ausgeschaltet wird. Dabei ist die Dauer des Einschaltens der Umwälzpumpe und des Ausschaltens der Umwälzpumpe abhängig von einem Spülflüssigkeitsniveau im Spülbehälter, welcher einem unteren Füllstandsniveau entspricht, bei dem die Umwälzpumpe keine Luft ansaugt. Aufgrund des vorstehend genannten limitierten Faktors bestehen weitere Abhängigkeiten zur Drehzahl der Umwälzpumpe, die mit zunehmender Drehzahl mehr Spülflüssigkeit dem Sumpf entnimmt. Die Gestaltung der Impulse des Ein- und Ausschaltens der Umwälzpumpe ist auch in Abhängigkeit einer Trübungsmessung der Spülflüssigkeit einstellbar, so kann bei geringem Verschmutzungsgrad die Dauer des Einschaltens der Umwälzpumpe gegenüber der Dauer des Ausschaltens der Umwälzpumpe verkürzt werden und bei erhöhtem Verschmutzungsgrad entsprechend verlängert werden. In Abhängigkeit einer pH-Wert-Messung und/oder der Temperatur der Flüssigkeit und/oder einer ermittelten Klarspülerkonzentration kann das maximal vorhandene Spülflüssigkeitsvolumen während eines flüssigkeitsführenden Verfahrensabschnittes, vorzugsweise im Verfahrensabschnitt Zwischenspülen, definiert eingestellt werden. So kann auf das Auflösungsverhalten und/oder die Konzentration des Klarspülers und/oder einer der anderen Substanz des Kombinationspräparates Einfluss genommen werden. Wird ein Kombinationspräparat verwendet, welches einen Klarspüler enthält, der ein temperatur- und/oder ph-Wert-abhängiges Auflösungsverhalten hat, ist ein bestimmter pH-Wert, vorzugsweise im neutralen pH-Bereich, während des Zwischenspülens zu erreichen. Dies setzt ggf. sowohl ein erhöhtes Spülflüssigkeitsvolumen während des Zwischenspülens voraus, als dass auch dieser pH-Wert durch einen oder mehrere vorgesehene Verdünnungsschritte während des Zwischenspülens erreicht werden kann.The intermediate rinsing during the liquid-carrying process sections can preferably be designed as pulse rinses, ie, during the process section intermediate rinsing, the circulation pump is repeatedly switched on and off for a predefinable or determinable duration. The duration of switching on the circulation pump and the switching off of the circulation pump is dependent on a level of Spülflüssigkeitsniveau in the washing, which corresponds to a lower level, at which the circulating pump sucks no air. Due to the above-mentioned limited factor, there are further dependencies on the rotational speed of the circulation pump, which withdraws more rinsing liquid from the sump as the rotational speed increases. The design of the pulses of switching on and off of the circulation pump is adjustable depending on a turbidity measurement of the rinsing liquid, so the duration of switching on the circulation pump can be shortened compared to the duration of turning off the circulation pump at low degree of contamination and extended accordingly with increased degree of contamination. In dependence of one pH measurement and / or the temperature of the liquid and / or a determined rinse aid concentration, the maximum existing rinsing liquid volume during a liquid-carrying process section, preferably set in the process section intermediate rinsing defined. Thus, the dissolution behavior and / or the concentration of the rinse aid and / or one of the other substances of the combination preparation can be influenced. If a combination preparation is used which contains a rinse aid which has a temperature and / or pH-dependent dissolution behavior, a certain pH, preferably in the neutral pH range, is to be achieved during the intermediate rinsing. This presupposes, if necessary, both an increased volume of rinsing liquid during the intermediate rinsing, as well as that this pH value can be achieved by one or more intended dilution steps during the intermediate rinsing.
In einem Ausführungsbeispiel ist die Erfindung anhand eines Verfahrens zum Betreiben einer Haushalts-Geschirrspülmaschine, welches für die Verwendung von 3in1-Kombinationspräparaten, also von solchen mit den Wirkstoffen Reiniger, Klarspüler und Enthärter, geeignet ist, näher erläutert.In one embodiment, the invention with reference to a method for operating a domestic dishwasher, which is suitable for the use of 3in1 combination preparations, ie of those with the active ingredients cleaner, rinse aid and softener, explained in more detail.
Dabei zeigt die einzige Figur ein Schema der einzelnen Verfahrensabschnitte eines Spülprogrammablaufes. Es wird dabei vorausgesetzt, dass das Wasser der Zuleitung im Wesentlichen weich ist und somit einen geringen Härtegrad aufweist.The single figure shows a schematic of the individual process sections of a washing program sequence. It is assumed that the water of the supply line is substantially soft and thus has a low degree of hardness.
Auf der Ordinate der Kurve A ist nicht maßstäblich die Zeit und auf der Abszisse ist nicht maßstäblich das im Spülbehälter vorhandene Spülflüssigkeitsvolumen aufgetragen. Einzelne wichtige Parameter für den Verfahrensablauf, die für ein besonders gutes Reinigungsergebnis des Spülgutes unverzichtbar sind, sind durch entsprechende Pfeile gekennzeichnet. Vorzugsweise zu Beginn des Spülprogrammes werden automatische Zudosierungsfunktionen, die keine "3in1"-Kombinationspräparatzugabe umfassen, ausgeblendet, dies betrifft in jedem Fall die automatische Zudosierung des Klarspülers, ferner wird die automatische Regenerierungsfunktion ausgeblendet. Aus der Figur ist ersichtlich, dass das Spülprogramm mit einem Vorspülen von sehr kurzer Dauer von 2 bis 5 Minuten bei Zuleitungstemperatur des Wassers durchgeführt wird.On the ordinate of the curve A is not the scale to the time and on the abscissa is not to scale the Spülflüssigkeitsvolumen present in the washing container applied. Individual important parameters for the procedure, which are indispensable for a particularly good cleaning result of the items to be washed, are indicated by corresponding arrows. Preferably, at the beginning of the rinse program, automatic dosing functions that do not involve a "3in1" combination preparation addition are hidden, in each case involving the automatic dosing of the rinse aid, and the automatic regeneration function is also hidden. From the figure it can be seen that the wash program is performed with a pre-wash of very short duration of 2 to 5 minutes at supply temperature of the water.
In diesem Programmabschnitt sind vorzugsweise dem Geschirrspüler keine chemischen Substanzen zur Verbesserung des Vorspülergebnisses zugesetzt. Es lässt sich dabei jedoch nicht verhindern, dass durch den Benutzer fälschlicherweise das 3in1-Kombinationspräparat schon vor Start der Geschirrspülmaschine zugeführt wurde. Nach vollständigem Abpumpen der Spülflüssigkeit am Ende des Programmabschnittes Vorspülen, gekennzeichnet durch Pfeil VV, wird frische Spülflüssigkeit dem Spülbehälter zugeführt. Diese ist auf ein vorgesehenes maximales Spülflüssigkeitsvolumen von ca. 4 1, bemessen auf eine Geschirrspülmaschine, die zur Aufnahme von 12 Normgedecken vorgesehen ist, begrenzt. Zu Beginn des Programmabschnittes Reinigen wird die Spülflüssigkeit durch Zuschalten vorgesehener Heizmittel aufgeheizt. Dabei soll die Spülflüssigkeit eine Temperatur von ca. 55 °C erreichen, was zum Zeitpunkt der Erfindung eine Temperatur unterhalb der Auflösungstemperatur des Klarspülers von pHund temperaturabhängig auflösbaren 3inl-Kombinationspräparat, wie beispielsweise Calgonit Powerballs®, entspricht. Im ersten Drittel des Programmabschnittes Reinigen wird das "3in1"-Kombinationspräparat, vorzugsweise während des Zuführens von Spülflüssigkeit, zugegeben (gekennzeichnet mit Pfeil 3in1).In this section of the program, preferably no chemical substances are added to the dishwasher to improve the prewetting result. However, it can not be prevented that the user mistakenly supplied the 3-in-one combination preparation even before the start of the dishwasher. After complete pumping out of the rinsing liquid at the end of the program section pre-rinsing, characterized by arrow VV, fresh rinsing liquid is supplied to the rinsing container. This is limited to a maximum volume of rinsing liquid of about 4 liters, measured on a dishwashing machine intended to hold 12 standard dishes. At the beginning of the program section cleaning, the rinsing liquid is heated by connecting provided heating means. In this case, the rinsing liquid should reach a temperature of about 55 ° C, which at the time of the invention, a temperature below the dissolution temperature of the rinse aid of pHund temperature-dependent dissolvable 3inl combination preparation, such as Calgonit Powerballs® corresponds. In the first third of the program section cleaning, the "3in1" combination preparation is added, preferably during the supply of rinsing liquid (indicated by arrow 3 in1).
Die Spülflüssigkeit wird bei der maximal vorgegebenen Temperatur ca. 10 bis 30 Minuten im Spülbehälter umgewälzt und hierdurch das zu reinigende Spülgut beaufschlagt. Am Ende des Programmabschnittes Reinigen wird die Spülflüssigkeit aus dem Spülbehälter nahezu vollständig entfernt (gekennzeichnet durch Pfeil VR). Das Spülflüssigkeitsvolumen wird für einen folgenden Programmabschnitt Zwischenspülen frisch aufgefüllt und ausschließlich durch Entnahme von Energie, die in den Wärmekapazitäten des Geschirrspülers gespeichert ist, aufgeheizt und umgewälzt. Das maximal zugeführte Spülflüssigkeitsvolumen kann in Abhängigkeit einer Trübungsmessung und/oder einer Konzentrationsmessung von vorhandenem Klarspüler, der nach dem Verdünnungsprinzip arbeitet, variiert werden. So ist, wie punktiert dargestellt, das Spülflüssigkeitsvolumen bei hohem Verschmutzungsgrad und/oder hohem Konzentrationsgrad des Klarspülers und/oder stark basischem Milieu der Spülflüssigkeit bevorzugt erhöht. Bei geringem Verschmutzungsgrad, schon recht niedriger Konzentration des Klarspülers bezüglich der Konzentration, die im Klarspülen von Nöten ist, und/oder bereits neutraler Spülflüssigkeit wird das Spülflüssigkeitsvolumen, wie strichiert dargestellt, erniedrigt.The rinsing liquid is circulated at the maximum predetermined temperature for about 10 to 30 minutes in the washing and thereby applied to the dishes to be cleaned. At the end of the program section cleaning, the rinsing liquid is almost completely removed from the rinsing container (indicated by arrow VR). The rinsing liquid volume is refilled for a subsequent program section intermediate rinsing and heated and circulated exclusively by removing energy stored in the heat capacity of the dishwasher. The maximum volume of rinsing liquid supplied can be varied as a function of a turbidity measurement and / or a concentration measurement of existing rinse aid which operates on the dilution principle. Thus, as shown in dotted lines, the rinsing liquid volume is preferably increased in the case of a high degree of contamination and / or a high degree of concentration of the rinse aid and / or strongly basic medium of the rinsing liquid. At a low degree of contamination, already quite low concentration of the rinse aid with respect to the concentration, which is necessary in the rinse, and / or already neutral rinsing liquid, the rinsing liquid volume, as shown in phantom, lowered.
Der Verfahrensabschnitt Zwischenspülen geht nach einem Verdünnungsschritt oder nach einem nicht gezeigtem vollständigem Abpumpen z.B. Abhängigkeit von Trübungsgrad in den Programmabschnitt Klarspülen über. Hierzu wird zumindest teilweise das Spülflüssigkeitsvolumen erhöht und erreicht vorzugsweise das maximal vorhandene Spülflüssigkeitsvolumen des Programmabschnittes Reinigen. Andererseits kann alternativ das Spülflüssigkeitsvolumen durch entsprechend ausgewertete Messergebnisse vorgesehener Sensoren auch genau auf einen vorgebbaren Konzentrationsbereich des Klarspülers eingestellt werden. Der Wert des dann zuzuführenden Spülflüssigkeitsvolumens muss durch die Recheneinheit der Programmablaufsteuerung errechnet werden. Somit variiert die Dauer des Zwischenspülens zwischen 2 bis 10 min und die Dauer des Klarspülens ca. zwischen 2 bis 15 min. Das Spülflüssigkeitsvolumen wird im weiteren Programmablauf nunmehr auf eine Temperatur oberhalb einer pH-Wert- oder temperaturabhängigen Auflösungstemperatur des Klarspülers erhöht, die Auflösetemperatur des Klarspülers liegt derzeit bei ca. 58 °C, so dass auf eine Mindesttemperatur im Klarspülen von 60 bis 70 °C aufgeheizt wird. Am Ende des Programmabschnittes Klarspülen wird die Spülflüssigkeit nahezu vollständig aus dem Spülbehälter entfernt (gekennzeichnet durch Pfeil VK). An den Programmabschnitt Klarspülen schließt sich ein Programmabschnitt Trocknen an, der jedoch hier nicht weiter dargestellt ist.The process section intermediate rinsing passes into the program section rinsing after a dilution step or after a complete pumping, not shown, for example depending on the degree of turbidity. For this purpose, the rinsing liquid volume is at least partially increased and preferably reaches the maximum rinsing liquid volume of the program section cleaning. On the other hand, alternatively, the rinsing liquid volume can also be adjusted precisely to a predeterminable concentration range of the rinse aid by appropriately evaluated measurement results of provided sensors. The value of the rinsing fluid volume to be supplied then has to be calculated by the arithmetic unit of the program sequence control. Thus, the duration of the intermediate rinsing varies between 2 to 10 minutes and the duration of rinsing approximately between 2 to 15 minutes. The rinsing liquid volume is now in the further program flow to a temperature above one The dissolution temperature of the rinse aid is currently approx. 58 ° C, so that it is heated to a minimum rinse temperature of 60 to 70 ° C. At the end of the rinse program section, the rinse liquid is almost completely removed from the rinse tank (indicated by arrow VK). The program section rinsing is followed by a program section drying, which, however, is not shown here.

H. all preset programs are designed for the use of ("3in1") combination preparations and an operable switching means allows adaptation to the use of individually stored or dispensable cleaning, rinsing and softening agents of the selected rinse program.
