Description

Dishwasher and procedure for operation of a dishwasher using a combined preparation with several active substances.

The invention relates to a dishwasher, in the that at least one rinse program can be selected and at a procedure for the operation of a dishwasher.

For a long time you can get the called combined preparations 3 in 1 for use in dishwasher, which together contain a substance of cleaning, a substance that reduces water hardness and a rinsing substance and that are fed at the same time rinse tank of the dishwasher at a certain time. These 3-in-1 combined preparations are available in the form of pressed tablets, the so-called 3-in-1 tablets as well as 3 in 1 powder. Combined preparations 3 in 1 can be inserted in dispensing devices provided for in the dishwasher, in this case they are dosed at a certain time, which is determined to through the dishwasher rinse program cycle, to rinse tank. On the other hand, they can also be placed through the dishwasher user in the dishwasher, for example in the cutlery basket, before connecting the program cleared up. In general, the user currently has more than one optional rinse program for cleaning item a rinse dirty introduced in the dishwasher. As programs of rinse optional programs have long been known  known by the names of short program, normal program, intensive program, economic program, for those who exist also the most different formations of synonyms concepts. Since the use of combined preparations 3 in 1 by the user of dishwasher customer claims have accumulated to the dishwasher manufacturers. Since the results of Drying of the item rinsed clean in the dishwasher have worsened, in part, drastically in the case of using 3-in-1 preparations versus conventional individual dosing. It has been revealed as especially problematic that, on the one hand, users do not observe the prescribed location of the preparation combined 3 in 1 in the dishwasher, so that many place 3-in-1 tablets in the dishwasher while prescribed by the manufacturer a use exclusively on the device of dosage. In addition, the indications of the manufacturers of the 3-in-1 combined preparations with respect to the selection of a adequate rinse program are not correct, since the Dishwasher user, in general, knows, in effect, what program rinse should be selected based on the degree of dirt and the degree of drying of dirt particles, but does not have a exact knowledge about the cycle of the clearing program itself. This knowledge involves the manufacturer of the combined preparation 3 in 1 in the user and can also be completely ignored, that different combined preparations are present in the market 3 in 1, which dissolve differently depending on the most different parameters and therefore they get in different moments maximum activity. So, for example, some prepared 3-in-1 combined that can be purchased commercially work from agreement with the so-called "dilution principle" (known also as a principle Carry over), that is, that is added to the beginning of cleaning the combined preparation 3 in 1 and begins to dissolve. In this case, the agent of rinsed in a high concentration, that is, in excessive dose and part of that due to the propagation in remains of chlorine water and to the adhesions of the rinse agent dissolved in article a rinse, on the walls of the rinse tank and on the roof of the rinse tank as well as in the feeding ducts, the concentration in the rinse process is still sufficient to achieve a particularly good drying result. Other embodiment of the combined preparation 3 in 1 provides that first dissolve only the detergent and the de-hardener and the rinse agent, which is encapsulated in the 3-in-1 combined preparation, which is present, for example, in form of a pearl coated with wax, it is first dissolved in function of the temperature and / or of the pH vapor during rinsing. Without However, in the case of using a rinse program, which already working in the cleaning program section with high temperatures and / or where the duration of the cleaning process is select very long, which is, in general, usual in the case of an intensive program, the rinse agent is already dissolved Second type mentioned. The first type rinse agent especially mentioned has the disadvantage that in the case of carrying out several sections of the cleaning program before of rinsing, such as cleaning, intermediate washing, being connected the latter, as is known, between the sections of the cleaning and rinsing program, dissolves too quickly and in this case it is no longer present in sufficient concentration in the rinse program section due to multiple change of rinse liquid. Another drawback in the case of using 3-in-1 combined preparations may appear when the user of the dishwasher carries out the dosage through the insertion, for example, from a 3-in-1 tablet, before the start of the program of rinse somewhere in the dishwasher, but not in the dose combined. In this case, for example in the program section of rinsed, detergent and detergent begin to dissolve de-hardener, and can be determined, in general, in tests of laboratory that the dissolution behavior of the preparations combined 3 in 1 is very good also in water, which presents essentially the temperature of the feed duct. By pumping medium, in the following sections of the program cleaning, where appropriate the planned program sections such as intermediate wash, rinse, the substances of the preparation Combined 3 in 1 are available in one more concentration reduced, which has a direct impact on both the cleaning result as well as the drying result of the clarified article and, in general, makes it worse.

The document DE-A-19957243 publishes a dishwasher, which is suitable for both operation with conventional detergents as well as for operation with Combined preparations An operator can select a program from corresponding rinse according to the detergent used in each case.

The purpose of the invention is to propose a dishwasher and a procedure for operating a dishwasher, which solves at least one of the drawbacks mentioned above and prepares a rinse program, which is adapted or adapted to the use of combined preparations with several active substances, and should be enabled from now on to the user the basic use of the rinse programs known so far and in this case should also be avoided yet that through an erroneous entry through the user is executed a 3-in-1 cycle, although no preparation is planned corresponding, or vice versa.

The aforementioned task is solved by means of a dishwasher according to the characteristics of claim 1 and by means of a procedure according to the characteristics of the claim 11.

In accordance with the device of the invention proposal, you can select in a dishwasher at least one rinse program, such as an intensive program, normal program, short program, economic program. Agree with the invention a rinse program is now proposed selectable of this type, which is defined itself for the use of a preparation combined with several active substances or at least one means is provided for the additional connection of a additional function, through which, in the case of a connection In addition to this function, at least one parameter can be modified of the selected rinse program with respect to the use of a preparation combined with several active substances. At dishwasher operated with this rinse program, according to another feature of the invention, at least one sensor, which recognizes if a combined preparation has been introduced in the dosing facility or elsewhere in the dishwasher. Such a structure has as a consequence that the rinse program selected by the user, such as intensive program, normal program, short program, program economically adapts automatically to the use of a combined preparation, especially comprising substance detergent, de-hardening substance and substance of cleared, when a sensor recognizes the presence of a preparation combined or even the default dishwasher itself a corresponding 3 in 1 program. That is, in the case of the solution of the additional function a corresponding signal is emitted to the control unit, which performs automatically an adaptation of the rinse program selected in each case depending on the user to use the combined preparation. TO for this purpose, for example, different execution routines are deposited of the program in the microcontroller of the control unit, at that is accessed, and / or accessed in a defined way to different parameters of the rinse programs, such as temperature, duration of a given section of the rinse program, volume of Filling liquid filling, pH value, etc. and in this way it Modify these parameters. In the other embodiment of the invention, a rinse program can be selected specially configured for special use with a prepared combined under other rinse programs than those can be selected automatically through the control of the program according to the installation detection of prepared.

In a preferred manner, the additional function or The special rinse program are designed for use of a combined 3-in-1 preparation, containing this preparation combined as specific active substances for cleaning the product to be washed essentially only detergent substance, de-hardening substance and clearing substance. Of one independently of these ingredients, the combined preparation 3 in 1 it can also present other substances, whose influence Direct or indirect on the result of cleaning and drying of individual sections of the rinse program or about the result of the general cleaning of the rinse program have a secondary importance. Although they are not expressly mentioned other specific active substances of the combined preparation, these, however, are also included to the extent that are known and can be influenced by the object of the invention.

In addition, a switching means is included for the additional connection of the additional function, being located this means in a preferred manner on the screen support of the dishwasher together with other means of selection and / or means of representation. Another possibility to arrange the means of switching offers the preparation dosing facility combined, in which the preparation is filled in a preferred manner combined. In the configuration of the switching medium are conceivable the most different known configurations, such as rotary pushbutton switches, keys or the like. Further, an activation of a switching means to through a selection depending on the user, which can be connect additionally through a selection on a device menu-guided selection, for example on a screen representation or in the case of appliances connected to the network through a graphic surface or, if necessary, a system Voice recognition

In the dishwasher it can be detected through at least one sensor intended to use a preparation combined, especially a combined 3-in-1 preparation, so that for the configuration of the execution of the program you can distinguish, on the one hand, if a combined preparation works from according to the dilution principle or a preparation is used combined, which dissolves the rinse agent already in the phase of clarified depending on the pH value and / or depending on the temperature. On the other hand, in the case of repeated measurement with sensor during The entire cycle of the rinse program can be determined by example, a modification of the concentration and / or the pH value and / or modifications of the degree of hardness of the rinse liquid, which allow conclusions about the concentration of individual active substances of the combined preparation 3 in 1, with the consequence that the program cycle can be modified in Any suitable moment.

As sensors, at least one of the sensors is configured as a chemical sensor and / or as an acoustic sensor and / or as thermal sensor and / or as an optical sensor and / or as a pneumatic sensor. These sensors can be configured different in number and in its specific detection property. In addition, an evaluation of Sensor signals can be used both with respect to the adaptation of the rinse program cycle in relation to the use of the combined 3-in-1 preparation as well as for configuration of the remaining parameters of the entire cycle of the washing program In addition, in an alternative way, at least one planned chemical sensor with shapely selected receivers corresponding, which is used for the detection, for example, of several active substances that appear at the same time, such as detergent and de-hardener and / or rinse agent, can recognize the use of a combined preparation or also without a connection additional function additional to the cycle control of the program, can signal the use of a combined preparation. Through control measurements, if necessary, repeated and / or in comparison with other sensor measurements during the cycle from the program, the use of a combined preparation and the program cycle is modified accordingly. Currently, the use of a sensor is especially preferred, which recognizes at least the pH value and / or the temperature and / or the degree of liquid hardness to rinse.

The expected sensors determine a continuously or discontinuously during the program cycle or during individual sections of the rinse program, whose temporary developments or whose instants can be determined at through program control, between individual parameters of the program, for example with a help of a comparison of theoretical value and the real value and / or a differential value and / or the development of the modification of a parameter, such as the pH value, the temperature, turbidity, foaming, concentration, water hardness, if an active substance determined of the combined preparation exceeds or does not reach exceeds or does not reach a predetermined minimum or maximum value. Also for example, result in a differential value, which can be derived, for example, depending on the manufacturer from prepared combined 3 in 1 proper, as well as with compared to other typical parameters, such as jumps of the concentration, dissolution temperatures or combinations of parameters such as pH value and concentration or concentration and rinse program cycle temperature. During an interval of determined time of a rinse program cycle or during the entire duration of the rinse program is detected from in the same way the modification of at least one parameter of the rinse program and is evaluated. Thus, for example, with respect to pH value development of the rinse liquid can be taken out conclusions on the concentration of active substances Individuals of the 3-in-1 combined preparation. In this way, currently the pH value assessment of such can be carried out way that the cleaning program section represents a value Maximum basic pH, or in the rinse program section should reach a predetermined value or, instead, its cycle of modification, for example in a field of characteristic curves default, is predefined within tolerances predetermined or jumps of the pH value are calculated (modification abrupt pH value) within previously specified time intervals defined or, on the other hand, time constants are determined for its appearance, for example after having reached the dissolution temperature of an encapsulated rinse agent. From according to the invention, such measurement of the sensors is used, when the additional function is connected, for the adaptation of a cycle of the clearing program when using a preparation combined for active intervention in the program cycle in yes, in the case of a configured rinse program cycle of special form, these have first of all a kind of function control to determine if during the program cycle actually used a combined preparation or is present at least a specific substance active at the predetermined instant in a sufficient concentration and can be done in a way optional adaptations of the rinse program cycle.

A suitable method for the evaluation of sensor signals consists in determining, for example, the value or the modification of certain program parameters rinse such as turbidity, pH value, foaming, concentration, water hardness, etc. in an individual way like also in suitable combinations at characteristic moments of rinse program cycle, with respect to its appearance qualitative and quantitative as well as with respect to their times of mutual delay. In this regard, within sections of time or predetermined time intervals can be calculated at least individual values of the parameters and these can be subjected to a comparison of the theoretical value and the real value, to a formation of the differential value or to a query of the threshold value or can make changes with respect to the values previously adjusted or calculated in the program cycle, being deposited all comparative values in tables or as values default in at least one memory unit of the control of the Program. In the case of appliances connected to the network, this memory unit can also be located outside the dishwasher. In addition, the memory unit can be memorized also certain program states, can be deposited combinations, for example, undesirable and these can force the user to certain manipulations. Such constellations do not desired result, for example, in the program section of prewash, when a high foam formation and / or clear oscillations of the pH value, or a predetermined concentration of the rinse agent during all the sections of the program or, instead, appear jumps of the concentration of the rinse agent independently of a certain temperature or a temperature cycle. He user, according to the error situation appeared, can be invited, for example, to carry out an introduction of a combined preparation in the dosed combination or instead interrupts the program cycle until it is carried out, by part of the user, a new commissioning of the dishwasher or, instead, at least the result of the measurement is indicated Recognized is wrong.

In the prewash or wash program section it can be foreseen that the instant of the actual dosage of the 3-in-1 combined preparation be further supervised, by example through an acoustic sensor the fall of a tablet from the dosing chamber in the reservoir of clear out. Other detection possibilities offer sensors optical, which record an intensified formation of the foam or chemical sensors, which evaluate the modification of the pH value of the rinse liquid.

With additional advantage, in the case of a combined preparation, if necessary, modified, in which, by For example, an enzymatic detergent substance with a activity temperature limit of approximately 30 ° C or a rinsing substance with a dissolution temperature of 58 ° C approximately, with sections of the program planned for it reduced time and, therefore, with a dissolution duration reduced, through the additional short-term connection, given the case also repeated and / or through the transfer of power controlled or regulated heating means in the sections of the prewash and / or intermediate wash procedure, the rinse liquid in a preferred manner at the end of the section respective procedure, so that for the sections following the cleaning or rinse procedure, which they are made with hot rinsing liquid, the substance respective chemistry can develop better and for longer its total activity Through preheating or intensified heating of the rinse liquid at the end of the previous section of the rinse program improves dissolution and, therefore, the activity of the detergent or the clarified during the time period of each section of the program. The energy fed in this case is comparable to that of an energy  of activation. With an expected temperature control or a temperature regulation can optimize the duration of the dissolution, concentration, acting time, instant the release of a chemical from the combined preparation 3 in one.

In this case it is especially advantageous that predetermined by the user the combined preparation 3 in 1 actually used in the control program as a parameter, by example through the entry on an image register, which recognizes, for example, the bar code of a combined preparation 3 in 1 or you can select 3-in-1 combined preparations that are can be purchased commercially and that are deposited in memory of the program or the use of a combined preparation determined by the user, being memorized the default information depending on the user a through the use of a combined 3-in-1 preparation determined or until information about modification or, instead, is consulted again at the beginning of each instant or a predetermined instant defined.

With additional advantage, during the consultation or well during the evaluation of information about the type and the method of administration of cleaning substances, rinsing and, if necessary, de-hardening, an unidentified product in a unique way as a combined preparation 3 in 1 can disconnect a selected 3-in-1 function in a wrong way to through the user or an error message can be issued in the case of selecting a 3 in 1 program.

In addition, it is advantageous that when the function 3 in 1 is connected, or in the case of selecting a program clarified 3 in 1, the representations are disconnected or deleted of states of the clearing program, which are connected in the conventional rinse programs with individual dosing of substances, such as, for example, the disconnection of an LED from indication at the instant of the regeneration process or an LED of indication, which requests the filling of rinse agent.

If selected through the user of the dishwasher after setting the dirty item to be cleaned in the dishwasher a rinse program, a wash program, it add a combined preparation in the dishwasher and it is represented, to through an additionally connected selection means optional, the use of a combined preparation, then the program cycle control, taking into account the function additional, it is expected that the cycle of the washing program will be modified selected and adapts in all its configuration to the use of a combined preparation. In this case, depending on the program of selected wash, individual or various parameters are adapted parameters of the different sections of the rinse program such as prewash, clean, intermediate wash, rinse, a manner described below automatically essentially in function of the evaluation of predetermined sensor measurements or they are modified in a fixed way by default. The stages shown in this case in the claims of the process with  regarding their sequence they do not represent a mandatory requirement for the wash program cycle, but can be selected from a specific way, for example depending on the use of a particular combination preparation or the type of preparation combined, they can be repeated and / or connected successive or may be followed by other stages of the procedure known itself.

In the case of using a combination dosed with reserve cameras usually separated for detergent substance and rinse substance, in the case of use of a combined 3-in-1 preparation, the function is suppressed of the dosage of the rinse substance and, where appropriate, of the detergent dosage in the washing program selected. In an alternative configuration, for example in the case of determination of the concentration of the rinse agent in function of a sensor, it is possible to dose this agent in the necessary quantities, compensating in this way, if necessary, the dilution losses of the preceding sections of the washing program. Yes during the wash program selected other opening moments are planned for the Dosing facility for the release of the most different substances, these are also blocked or the instant of dosing of a certain substance and / or Modify the dosage of the quantity.

If the combined preparation is added, in addition to the detergent substance and rinse substance, also a de-hardening substance, which should make the darkening in a known way in the dishwasher to through a device intended for de-hardening, then agent regeneration is not required either de-hardener, which must be performed, as is known, in a dishwasher, with saturated saline solutions (brine), so that the regeneration function is suppressed in the program cycle, that is, the addition of a defined brine volume to the de-hardening device, which is otherwise provided in a defined moment of the program cycle. In one way alternative, if a hardness sensor is provided, which can determine the water hardness of the washing liquid, it can, if necessary, monitor the water hardness of the liquid of washing that is actually present in the dishwasher due to de-hardening agent with the de-hardening substance of the prepared combined and, if necessary, can be connected additionally the regeneration function of the de-hardener, of so that a partial de-hardening of the water is carried out at through the de-hardening device. In hard water regions, of according to experience, the ability to de-hardening of the de-hardening substances of a prepared combined 3 in 1. Therefore, it is especially advantageous that the information on the degree of hardness of the water used actually in the feed duct enter the configuration of the program cycle. The degree of water hardness can be entered by the user through an input function specially planned, for example on the control screen and can can be memorized or can also be set in an installation of mixing, in which corresponding means transmit the value of water hardness adjustment to program cycle control and when the 3 in 1 function is connected or in the case of the selection of a 3-in-1 washing program, enable connection additional regeneration function and / or at least the mixture of hard water with soft water at least in an instant predetermined.

It is planned to drive the water supply performed so far additionally through the device de-hardening independently of its ability to de-hardening, which runs out as the number of changes of washing liquid depending on the degree of hardness of the water fed. All other alternatives for the admission of water are, in effect, theoretically possible, but they are only convenient when they can be obtained, according to the standard, only still prepared combined with a substance of thinning The volume of water reserved, if necessary, of a defined way in the reservoir of the dishwasher to The regeneration function can be used especially in soft water regions alternately as total defined volume or partially in sections of the program that conduct liquid to the measurement of a predetermined volume of liquid.

If recognized through a sensor during a initial prewash the use of a combined preparation or its use is represented through the function additional connected, then you can shorten the duration of the prewash program section planned first with the in order to prevent the active substances of the detergent and the rinse agent included dissolve too soon and are present in the wash or rinse sections in concentration too low. If, on the other hand, it is selected a washing program, which provides two or more prewash sections with respective complete water change, then it is already prevented from prophylactic form through the omission of at least one prewash or well through the reduction to a section of the program pre-washed in this way also without the detection of a preparation combined, that a combined preparation is dissolved too soon wrongly inserted in the dishwasher instead of being introduced in the dosed combination.

If as already described above, the Prewash procedure stage is shortened or deleted totally, then in this way the time of the drive of the article to be washed with water, and shortened or removed totally in this way the dirt dilution process strong, which have possibly already adhered in the article to wash for a long time. This is not favorable in many cases. of dirt for a good cleaning result. Therefore in such cases the section of the cleaning procedure is prolonged in the measure of the duration of the procedure section, in order to shorten the prewash procedure section. This way, the onset of particle dissolution is shifted of dirt at least partially to the procedure section of cleaning.

In a particularly preferred way, it is reduced the number of intermediate wash sections between sections of the cleaning and rinsing program to a section of intermediate wash, which essentially has the task of eliminating the individual dirt particles that remain suspended and Chemical waste from cleaning. With additional advantage, the intermediate washing can be carried out with a maximum volume reduced washing liquid compared to the maximum expected volume of washing liquid from the cleaning program section, so that the concentration of the clarifying agent dissolved is higher than with a volume of washing liquid of the same magnitude as in the washed. If during the cleaning program section it is diluted several times the washing liquid and / or has been recognized through a corresponding measurement of turbidity a degree of dirtiness reduced washing liquid, then it can be dispensed with, given the case, totally from the intermediate wash section.

In the washing procedure section intermediate, which is carried out with mild washing liquid and, therefore, no active heating is planned through of the additional connection of heating elements provided, extracts the energy fed during the sections of the procedure, which are operated with hot washing liquid. To configure the procedure cycle in a favorable way from the energy point of view and also with water economy, as described above and, therefore, with the effect of the concentration of the clarifying agent is increased in the stage of the intermediate washing procedure, may be provided introduce the washing liquid as a pulse rinse about the item to be washed through the connection and disconnection Repeated circulation pump with a duration default and / or predefined different from the connection status and circulation pump disconnection. When you disconnect the circulation pump, the circulation of the liquid from wash and, therefore, the drive of the article to be washed with washing liquid This type of pulse rinse is described in an abbreviated way with an injection sequence, pause, injection, pause, injection pause and so on.

At the end of at least one section of the procedure, such as intermediate washing, may be planned a dilution stage depending on the measurement of the turbidity and / or configuration of the chlorinating agent in the washing liquid The dilution stage causes a partial volume of the washing liquid, which has been used during washing intermediate, be used additionally in the next stage of rinse procedure and be mixed with washing liquid Again, that is fed. Due to the dilution stage, it is reduced the loss especially of clarifying agent in front of a pumping of Complete discharge and a filling of washing liquid. Precisely for this reason, it can also be provided, in a way independent of the measurement of the turbidity of the washing liquid in a forced way a dilution stage instead of a pumping of complete discharge of the washing liquid, for example at the end of a wash program section.

As another stage or alternative stage is reduced from a preferred way the temperature in the sections of the procedure that are placed before the program section of clarified, in a preferred manner in the process step of cleaning, at a temperature below the temperature of dissolution of the rinse agent, preferably below 58 ° C. In this way, for example, in the event that selected an intensive program, which develops in a way usual with the cleaning section at temperatures between 58 and 70ºC, it is prevented that in the case of using a combined preparation with release, depending on the temperature, of the substance of clarified, it dissolves, if necessary, already here and, therefore, is present in too low concentration in the section of rinse program

In the rinse program section, heats the article to be washed at a temperature of at least 58 ° C to the next section of the drying program, so that It also enables the dissolution of the clearing agent as a function of the temperature and / or, as the case may be, depending on the pH value.

With advantage, the temperature conduction of the washing liquid during a selected washing procedure, which has been automatically adapted to the use of combined preparations, as mentioned above, is determined, on the one hand, through the temperatures of dissolution of individual chemical substances. For other part, from energy points of view, during prewash, if is carried out, lar's liquid does not heat through heating means provided additionally connected, so that the washing liquid essentially depends on the temperature of the intake water During cleaning and rinsing heats up Actively wash liquid due to media connection heaters provided and heated in the program section gives intermediate washing without additional connection of these means heaters passively, that is, through the extraction of energy from the thermal capacities of the dishwasher, clearly at a temperature below the temperature of dissolution of a rinse agent dependent on the temperature.

Without limiting the invention, it is possible to make components of the wash program are executed with the 3-in-1 function selected in whole or in part according to a program default defined or fully or partially adapt to through the recognition and evaluation of certain parameters, for example through sensors, in a manner appropriate to the real situation with respect to a theoretical situation default

Additional connection of the 3 in 1 function or Well the selection of a 3-in-1 washing program, can be connected if necessary, in addition, also in appliances connected to the network, which are operated depending on the place by a computer central not located in the dishwasher.

In addition to the selected wash programs already known as normal program, intensive program, program economic, short program, a program can also be planned 3-in-1 special wash, which is adapted from the beginning to the use of combined preparations, especially those that contain detergent, de-hardener and rinse agent weather. This 3-in-1 wash program is directly selected through the dishwasher user and is characterized by essential stages of the procedure that are mentioned to then they represent the mentioned sequence but the sequence mentioned in this case not necessarily forced from stages of the procedure represent in this respect a possible cycle of the wash program if the final section of the program drying:

Modification or disconnection of the function of the de-hardening of the regeneration and / or modification facility or disconnection of the opening of special reserve cameras of the dosing device for special chemicals stored, in addition, individually next to the preparation combined (detergent, rinse agent) and / or modification of the Dosage amount of chemical substances stored

Disconnection of representation elements corresponding functions, which are disconnected beforehand, is that is, that are adjusted previously, during the program cycle to least through the control of the program cycle, in a way preferred disconnection of the regeneration representation with the regeneration function disconnected through the installation of regeneration and / or disconnection of the filling representation of the rinse agent in case at least the dosage Automatic rinse agent is disconnected.

The prewash is carried out with cold water, which depends, therefore, essentially on the intake temperature of water, for an extraordinarily short period of time between 2 and 5 minutes, preferably between 2 and 3 minutes. In this time, you can dissolve mainly fresh dirt and soils that have adhered for a long time can be softened weather. Based on this optional turbidity measurement, in the case of strong dirt, one or several stages may be provided of dilution of the washing liquid, with a stage of dilution by virtue of the brevity of the prewash, in a way preferred the end of prewash. If no stage takes place of dilution at the end of the prewash, then the liquid before the next section of the program.

The washing liquid fed in this case again, which may be diluted and therefore contaminated in a to a certain degree, it is now heated at the stage of the procedure of cleaning at a temperature, which is below the temperature of dilution of the rinse agent, preferably between 40 and 57 ° C.

The combined preparation is fed through of the dosing device in a preferred manner within the first third of the cleaning program section to the tank of wash, if the combined preparation has not been introduced through of the user before the start of the washing program in the tank to wash, for example, in the cutlery basket.

At the temperature mentioned above it circulates the washing liquid in the washing tank for cleaning between 10 and 30 minutes and is pumped completely or diluted at the end of the cleaning procedure section. This decision it can be taken based on a measurement of the turbidity of the rinse liquid that is optionally carried out.

If at least one measurement of the turbidity of the rinse liquid, then it can be carried out optionally a multi-stage dilution embodiment in function of the degree of dirtiness and / or the concentration of the individual ingredients of the combined preparation. To the section of cleaning procedure follows a section of the procedure of intermediate wash, in which the new or diluted washing liquid that is now present passively heated, that is, exclusively through the extraction of energy from thermal capacities of the dishwasher, so that it eliminates during its circulation the last remains of dirt that are still present and chemical waste from the section of cleaning procedure The cleaning liquid circulation takes place in the intermediate washing procedure section for a period of time between 2 and 10 minutes. In one way Alternatively, intermediate washing can also be performed as pulse washing with a reduced maximum volume of liquid wash in relation to the maximum volume of washing liquid of the cleaning.

The washing procedure section intermediate ends with a total or partial emptying.

In the rinse procedure section, feed the wash tank a defined volume of liquid from to wash. This can be fixed from the beginning. and / or can be adjusted in a variable way depending on the most different parameters A dependent variable is in this case the concentration of the clarifying agent that is present in this case really in the washing liquid, since it has a direct influence on the result of the rinse and, therefore, on the result of the following selective drying of article a to wash. Thus, for example, in the case of a reduced concentration of the clarifying agent at the beginning of the program section of rinse, the smallest amount of washing liquid is fed possible, but given, the case, depending on the degree of turbidity of the washing liquid If otherwise the concentration of the agent chlorinate at the beginning of the clarification program section is by above average or is high enough, then you can adjust the concentration of the rinse agent through the feeding a volume of washing liquid adjusted so defined at a predetermined concentration. Washing liquid with chlorinating agent already dissolved, as well as the washing liquid with chlorinating agent yet to dissolve, it is now heated from a preferred way at a dissolution temperature above the dissolution temperature of a rinse agent that dissolves depending on the pH value and / or depending on the temperature. This dissolution temperature is currently above 58 ° C (for the combined preparation 3 in 1 Calgonit Powerballs®. During a period of time between 2 and 15 minutes, but in the same way at less until a predetermined temperature is achieved with preferably between 65 and 70 ° C, the liquid is heated clarify and circulate. At the end of the program section of rinse the washing liquid is removed as much as possible to through pumping from the wash tank.

The residual liquid and water vapor that they remain in the article to be washed, on the roof of the tank wash, on the walls of the wash tank is removed in the section of the drying program that follows the program section of clear out. Drying is carried out in this case in a manner preferred as condensation drying. During drying by condensation connects at least one air circulation blower, if present, in a preferred manner in the first third of This section of the program.

Intermediate washing during sections of the procedure that conduct liquid can be configured in a preferred way as pulse washing, that is, during the intermediate washing procedure section, connects and disconnect the circulation pump periodically for a predetermined or determinable period of time. In this case, the duration of the connection of the circulation pump and the Disconnection of the circulation pump is a function of a level of filling liquid in the wash tank, which corresponds to a lower level of filling, in which the circulation pump does not breathe air Under the limited factor mentioned previously, there are other dependencies with respect to the number of revolutions of the circulation pump, which extracts more and more wash liquid from the sump as the number increases of revolutions. The connection pulse configuration and circulation pump disconnection can also be applied as a function of a liquid turbidity measurement of wash, so that, in the case of a degree it is reduced dirt, the duration of the pump connection can be shortened circulation with respect to the duration of the pump disconnection of circulation and in the case of a high degree of dirt, It can be extended to a corresponding extent. Depending on one measurement of the pH value and / or the temperature of the liquid and / or a Calculated concentration of the rinse agent can be adjusted from a defined way the maximum volume of washing liquid present during a section of the procedure that conducts liquid, from a preferred way in the washing procedure section intermediate. Thus, for example, an influence can be exerted on the dissolution behavior and / or the concentration of rinsing agent and / or one of the other substances of the preparation combined. If a combined preparation is used, it contains a rinsing agent, which has a dissolution behavior in function of the temperature and / or depending on the pH value, it can be achieve a certain pH vapor, in a preferred manner in the Neutral pH range, during intermediate washing. This presupposes, if necessary, both a high volume of the liquid wash during intermediate washing, as can also be achieved this pH value through one or several expected dilution stages during intermediate washing.

The following explains in detail the invention in an exemplary embodiment, with the help of a procedure for the operation of a domestic dishwasher, which is suitable for the use of combined preparations 3 in 1, that is, of those that contain the active substances detergent, rinse agent and de-hardener.

In this case, the single figure shows a scheme of the individual sections of the procedure of a cycle of rinse program In this case, it is assumed that the water in the intake duct is essentially soft and therefore It has a reduced degree of hardness.

On the ordinate of curve A it is recorded, in a form not to scale, time and on the abscissa is represented, in a non-scale way, the volume of washing liquid, which is present in the wash tank. The important parameters individual for the procedure cycle, which are essential to achieve a cleaning result especially good of the item to be washed, they are identified by middle of corresponding arrows. In a preferred way, at start of the washing program automatic functions are suppressed Dosage, which do not include the contribution of the preparation combined 3 in 1. This refers in any case to the automatic dosing of the rinse agent, it is also suppressed Automatic regeneration function. From the figure you clearly deduces that the washing program is carried out with a prewash with a very short duration between 2 and 5 minutes at water intake temperature. In this section of the program you don't know add in a preferred way to the dishwasher no substance Chemistry for the improvement of the prewash result. However, in This case cannot be prevented through the user mistakenly provided the combined preparation three in 1 before the start-up of the dishwasher. After discharge pumping  Complete washing liquid at the end of the program section prewash, identified by means of the arrow VV, is fed clean wash liquid to the wash tank. This one is limited to a maximum expected washing liquid volume of approximately 4 liters, adapted to a dishwasher, which is intended for reception of 12 standard cutlery. At the beginning of the section from the cleaning program the washing liquid is heated through of the additional connection of heating means provided. In this case, the washing liquid must reach a temperature of approximately 55 ° C, which corresponds at the time of invention at a temperature below the temperature of solution of the rinse agent of the combined preparation 3 in 1, which dissolves depending on the pH value and depending on the temperature. In the first third of the program section of cleaning the combined preparation is added, in a preferred manner during the feeding of washing liquid (identified by of the arrow 3 in 1).

The washing liquid is circulated to a default maximum temperature between approximately 10 and 30 minutes in the wash tank and in this way the item to wash. At the end of the cleaning program section the washing liquid is almost completely removed from the tank wash (identified by means of the VR arrow). The volume of washing liquid is refilled again during a next section of the program and heats up exclusively through the energy extraction, which is memorized in the capacities thermal of the dishwasher, and it is circulated. The maximum volume of fed washing liquid can be varied depending on the agent to clarify present, which works according to the principle of dilution. In this way, as represented by dotted lines, the volume of the rinse liquid is preferably high in the case of a high degree of dirt and / or a high degree of concentration of the rinse agent and / or of a medium strongly Basic washing liquid. In the case of a degree of dirt reduced, already with a really low concentration of the agent clarify regarding the concentration, which is necessary in the rinsing, and / or with a neutral washing liquid, the volume is reduced of the washing liquid, as represented by dashed line.

The washing procedure section intermediate passes, after a dilution stage or after a complete discharge pumping not shown, for example depending on the degree of turbidity, to the section of the program to clarify. To that end the volume of washing liquid is raised at least partially and reaches in a preferred way the volume of washing liquid maximum present of the cleaning program section. For other part, alternatively you can adjust the volume of the washing liquid through measurement results correspondingly evaluated sensors provided also exactly at a predetermined concentration range of rinse agent The value of the volume of washing liquid that must be fed then it must be calculated through the unit of Program cycle control calculation. In this way, the Intermediate wash duration varies between 2 and 10 minutes and the Rinsing duration varies approximately between 2 and 15 minutes. He volume of washing liquid rises in the other program cycle to then at a temperature above a temperature of solution of the rinse agent depending on the pH value or in temperature function, the temperature being at this moment of dissolving the rinse agent at approximately 58 ° C, of so that it is heated to a minimum rinse temperature between 60 and 70 ° C. At the end of the rinse program section, removes the washing liquid almost completely from the tank wash (identified by means of arrow CK). In the section of rinse program connects a section of the drying program, which is not represented, however, here in detail.

Without limiting the invention, all indications, which comprise numerical values, are adapted to 3-in-1 combined preparations currently available in the Calgonit Powerballs® market, Somat 3in1®, Sun 3in1 Optimal®). With corresponding modifications of the composition of these 3 in 1 preparations can be adapted accordingly the parameters mentioned with values indications numeric

Without limiting the invention, it is also conceivable a program cycle setting or a procedure, in which the invention described above is reversed, that is, that all preset programs are designed for use of combined preparations (3 in 1) and through a medium switchable switching is possible an adaptation to the use of individual cleaning agents, rinsing agents and stored or dosible de-hardening of the program selected wash.
