Washing programs are usually associated with a dial and laundry temperature, e.g. Easy to clean 30 ° C or coloreds 60 ° C. By selecting the dialing temperature, the washing machine user sets the laundry temperature at which he wishes to wash the laundry.
- laundry temperature refers to the temperature at which the laundry is washed in the post-wash step, i. the actual temperature measurable in the washing machine during the final washing. The dial temperature is in this sense the target temperature during the Nachwasch intimids, while the wash temperature represents the actual temperature during the Nachwasch intimids.
- the post-washing step is carried out according to the specifications of the set washing program, regardless of whether the circulating device is activated or not.
- the laundry is moved by means of a rotating drum over a specified by the wash program Nachwasch period.
- the washing liquid covers the radiator disposed in the tub, but is below the drum. That is, before the heating step washing liquid has been introduced into the tub, wherein it has moistened the laundry located in the drum. The laundry has taken up washing liquid, but there is no free liquor in the drum.
- the washing liquid is heated by means of the radiator to the predetermined by the washing program wash temperature.
- the radiator is turned on, a temperature stratification sets in, which leads to microsolation occurring on the radiator surface after a period of time. Because of the short distance to the surface, the vapor bubbles manage to persist there, and they exit as vapor.
- the laundry Since energy can be transmitted via the natural propagation behavior of the steam in principle into the wet laundry, the laundry is heated to the predetermined by the selection temperature wash temperature. After reaching the predetermined laundry temperature or a predetermined heating step for the heating step, the heating of the washing liquid is stopped. After the heating step, the post-washing step is carried out.
- washing liquid is conveyed from the lower region of the tub into the upper region of the tub.
- the lower portion of the tub is within the meaning of the present invention, the bottom of the washing machine.
- the sump is the lower part of the washing machine, in which the washing liquid introduced into the tub accumulates by gravity and is located below the drum.
- the upper portion of the tub in the context of the present invention, the area of the tub, which is located above the bottom.
- the Umflut shark is activated during the Nachwasch intimids if the selection temperature is less than or equal to a threshold temperature.
- the relation of the temperature of the washing liquid at the lower region of the tub to the selection temperature plays a particular role in the decision as to whether the activation of the circulating device makes sense or not.
- the limit temperature therefore preferably depends on the temperature theoretically expected or measured during the heating step of the washing liquid located in the lower region of the tub.
- the limit temperature is preferably equal to the temperature of the washing liquid located in the lower region of the lye container, or preferably up to 5 ° C. higher.

- the temperature of the washing liquid located in the lower region of the tub is about 45.degree.
- the selection temperature is equal to or up to 5 ° C higher than the temperature of the washing liquid located in the lower part of the tub, so in the above example to 50 ° C, then probably the temperature of the laundry is not increased but rather slightly reduced, but one Increasing the washing liquid in the laundry by activating the flooding device can contribute to the improvement of the washing effect.
- the limit temperature is preferably between 40 ° C and 60 ° C, more preferably between 45 ° C and 50 ° C.
- the temperature of the washing liquid located in the lower part of the tub can vary at the end of the heating step.
- the temperature of the washing liquid located in the lower region of the tub is in the range of 35 to 55 ° C, more in the range of 40 to 45 ° C.
- the flooding device is deactivated after activation as a function of the washing liquid level and / or time-dependent. If no washing liquid can be pumped out of the sump, the circulating device is preferably deactivated so that it does not become damaged.
- the method may include a time control of the circulating device and / or a control fluid level-dependent control for determining the time of deactivation of the circulating device.
- the method may be deactivated after activation of the flooding device after a predetermined deactivation period.
- the Umflut can also be deactivated depending on the washing liquid level in the lower portion of the tub, which can be determined for example by means of sensor means.
- the flooding device is deactivated as a function of the washing liquid level when the amount of washing liquid to be conveyed by the flooding device is below a predetermined washing liquid quantity threshold value. Whether the amount of scrubbing liquid to be conveyed is below the predetermined scrubbing liquid amount threshold value depends on the level of scrubbing liquid in the lower area of the scrubber and can be determined, for example, by means of a sensor.
- the predetermined washing liquid quantity threshold value is preferably chosen such that the circulatory device is not damaged during the delivery due to an insufficient amount of washing liquid available to the washing liquid and / or its operation is ineffective.
- the flooding device is reactivated when the wash liquid level in the lower portion of the tub is above a predetermined wash liquid level threshold.
- the Umflut headphones can be operated at intervals. Whether this makes sense can be determined for example by means of sensors which measure the washing temperature and the washing liquid temperature in the lower region of the tub. When the ratio of wash temperature and wash liquid temperature in the lower Area of the tub results that activation of the Umflut Vietnamese contributes to the efficiency of the process, the Umflut Marie is activated, otherwise not.
- the method is such that, in the case of activation of the flooding device, the flooding device at the beginning of the post-washing step, i. after the end of the heating step, is activated.
- the circulating device is deactivated during the Nachwasch intimids when the circulating device is no longer sufficient to be pumped washing liquid available and / or when a predetermined activation period has expired.

- an amount of energy expended for operating the radiator during the heating step is adjusted such that the laundry temperature corresponds to the selection temperature.
- the washing machine user sets the target temperature for washing the laundry in the post-washing step.
- the washing temperature ie the actual temperature during the subsequent washing step, depends essentially on 3 input variables: 1. the selection temperature, 2. the amount of washing liquid and 3. the mixing temperature of washing liquid and laundry.
- the mixture of washing liquid and laundry results from the fact that the laundry absorbs the washing liquid introduced before the heating step.
- the filled amount of the washing liquid is adjusted so that there is no free liquor in the drum, the amount of washing liquid to be heated is in the lower portion of the tub, so that it covers the radiator but is below the drum.
- Selecting the selection temperature sets the temperature to be reached.

- the circulating device is deactivated when a predetermined period of time has elapsed and / or when the washing liquid level in the lower region of the tub has dropped to a level such that the circulating pump can no longer completely draw in washing liquid. If the dialing temperature is more than 45 ° C, the post-washing step Na is carried out without activating the circulating device.
- the washing phase Wa is terminated by pumping out the washing liquid from the tub, wherein the drainage device is activated and the washing liquid is removed from the tub as far as possible. If necessary, the drum is operated at a high speed in order to remove the washing liquid present as a bound liquor from the textile fibers of the laundry as much as possible. Subsequently, fresh washing liquid, which consists essentially of water, is introduced into the tub. Then, a rinsing phase Sp starts, in which the drum moves the laundry in the washing liquid. Optionally, during the rinsing phase Sp, the flooding device can be activated. At the end of the rinsing phase Sp, the rinsing liquid is pumped off and removed via the drainage device.
- a spin phase Sc which serves to drain the laundry.
- the drum is rotated at a speed, so that the laundry is applied to the drum shell and the washing liquid is pulled out of the laundry through the openings of the drum due to the centrifugal force.

Description
Die Erfindung betrifft ein Verfahren zum Betreiben einer Waschmaschine mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit zum Behandeln von Wäsche, einer in dem Laugenbehälter drehbar gelagerten Trommel zur Aufnahme der Wäsche, einem Heizkörper und einer Umfluteinrichtung zum Fördern von Waschflüssigkeit aus einem unteren Bereich des Laugenbehälters in einen oberen Bereich, bezogen auf die betriebsgemäße Aufstellposition der Waschmaschine. Das Verfahren weist die Durchführung eines Waschprogramms mit einer vorbestimmten Anwahltemperatur auf. Das Waschprogramm weist einen Heizschritt und einen Nachwaschschritt auf, wobei während des Heizschritts ein Waschflüssigkeitspegel in dem Laugenbehälter ausgebildet ist, sodass der Heizkörper unterhalb des Waschflüssigkeitspegels und die Trommel oberhalb des Waschflüssigkeitspegels liegt, bezogen auf die betriebsgemäße Aufstellposition der Waschmaschine, und Dampf mittels Betreiben des Heizkörpers erzeugt wird. Der Nachwaschschritt wird nach dem Heizschritt durchgeführt. Während des Nachwaschschritts wird die Wäsche in der Trommel bewegt.The invention relates to a method for operating a washing machine with a tub for holding washing liquid for treating laundry, a rotatably mounted in the tub drum for receiving the laundry, a radiator and a Umfluteinrichtung for conveying washing liquid from a lower portion of the tub in a Upper area, based on the operating position of the washing machine. The method includes performing a wash program at a predetermined dial temperature. The washing program comprises a heating step and a subsequent washing step, wherein a washing liquid level is formed in the tub during the heating step so that the heating body is below the washing liquid level and the drum is above the washing liquid level based on the operating position of the washing machine and steam by operating the heating body is produced. The post-washing step is carried out after the heating step. During the post-washing step, the laundry is moved in the drum.
Am Ende des Heizschritts befindet sich aufgewärmte Waschflüssigkeit in dem unteren Bereich des Laugenbehälters, die während des Nachwaschens ungenutzt ist, weil sie nicht mit der Wäsche in der Trommel in Berührung kommt. Die Erwärmung von Waschflüssigkeit, die nicht zum Waschen genutzt wird, ist nicht effizient.At the end of the heating step, warmed up scrubbing liquid is located in the lower portion of the tub, which is unused during the post-washing because it does not come into contact with the laundry in the drum. The heating of washing liquid that is not used for washing is not efficient.
Der Erfindung stellt sich somit das Problem, ein Verfahren zum Betreiben einer Waschmaschine und eine Waschmaschine bereitzustellen, die effizienter sind.The invention thus faces the problem of providing a method of operating a washing machine and a washing machine which are more efficient.
Erfindungsgemäß wird dieses Problem durch ein Verfahren mit den Merkmalen des Patentanspruchs 1 und eine Waschmaschine mit den Merkmalen des Patentanspruchs 10 gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a method having the features of patent claim 1 and a washing machine having the features of patent claim 10. Advantageous embodiments and further developments of the invention will become apparent from the following subclaims.
In dem Verfahren wird die Umfluteinrichtung während des Nachwaschschritts in Abhängigkeit von der Anwahltemperatur aktiviert. Die Umfluteinrichtung wird insbesondere dann aktiviert, wenn es effizient ist, die im unteren Bereich des Laugenbehälters erwärmte Waschflüssigkeit in den oberen Bereich des Laugenbehälters zu fördern und dadurch für eine Durchmischung der Waschflüssigkeit mit der Wäsche zu sorgen.In the method, the flooding device is activated during the subsequent washing step, depending on the selection temperature. The circulating device is activated, in particular, when it is efficient to convey the washing liquid heated in the lower region of the tub into the upper region of the tub, thereby ensuring thorough mixing of the washing liquid with the wash.
Die mit der Erfindung erreichbaren Vorteile bestehen neben einer verbesserten Effizienz darin, dass bei Aktivierung der Umfluteinrichtung eine bessere Durchmischung von Waschflüssigkeit und Wäsche erreicht und dadurch die Waschwirkung erhöht werden kann. Wenn es hingegen nicht effizient ist, die Umfluteinrichtung zu aktivieren, wird der Nachwaschschritt ohne Aktivierung der Umfluteinrichtung durchgeführt. Die Aktivierung der Umfluteinrichtung in Abhängigkeit der Anwahltemperatur während des Nachwaschschritts befähigt daher, das Verfahren derart zu führen, dass eine gute Waschwirkungs- und Energiebilanz erzielt werden kann.The achievable with the present invention consist in addition to improved efficiency is that when activated the Umfluteinrichtung a better mixing of Washing liquid and laundry reached and thereby the washing effect can be increased. On the other hand, if it is not efficient to activate the flooding device, the post-wash step is performed without activating the flooding device. The activation of the flooding device as a function of the selection temperature during the subsequent washing step therefore enables the process to be carried out in such a way that a good washing effect and energy balance can be achieved.
Im Sinne der vorliegenden Erfindung meint der Ausdruck "Anwahltemperatur" die Temperatur, die ein Waschmaschinennutzer mittels Auswählen eines durchzuführenden Waschprogramms einstellt. Waschprogramme sind üblicherweise mit einer Anwahl- und Wäschetemperatur verknüpft, z.B. Pflegeleicht 30°C oder Buntwäsche 60°C. Mittels Auswählen der Anwahltemperatur stellt der Waschmaschinennutzer die Wäschetemperatur ein, bei der er die Wäsche waschen möchte. Der Ausdruck "Wäschetemperatur" bezeichnet die Temperatur, bei der die Wäsche in dem Nachwaschschritt gewaschen wird, d.h. die tatsächlich in der Waschmaschine während des Nachwaschens messbare Temperatur. Die Anwahltemperatur ist in diesem Sinne die Soll-Temperatur während des Nachwaschschritts, während die Wäschetemperatur die Ist-Temperatur während des Nachwaschschritts darstellt. Der Nachwaschschritt wird entsprechend den Vorgaben des eingestellten Waschprogramms ausgeführt, unabhängig davon, ob die Umfluteinrichtung aktiviert wird oder nicht. Während des Nachwaschschritts wird die Wäsche mittels rotierender Trommel über eine vom Waschprogramm vorgegebene Nachwasch-Zeitdauer bewegt.For the purposes of the present invention, the term "dialing temperature" means the temperature that a washing machine user sets by selecting a washing program to be performed. Washing programs are usually associated with a dial and laundry temperature, e.g. Easy to clean 30 ° C or coloreds 60 ° C. By selecting the dialing temperature, the washing machine user sets the laundry temperature at which he wishes to wash the laundry. The term "laundry temperature" refers to the temperature at which the laundry is washed in the post-wash step, i. the actual temperature measurable in the washing machine during the final washing. The dial temperature is in this sense the target temperature during the Nachwaschschritts, while the wash temperature represents the actual temperature during the Nachwaschschritts. The post-washing step is carried out according to the specifications of the set washing program, regardless of whether the circulating device is activated or not. During the Nachwaschschritts the laundry is moved by means of a rotating drum over a specified by the wash program Nachwasch period.
Während des Heizschritts bedeckt die Waschflüssigkeit den in dem Laugenbehälter angeordneten Heizkörper, befindet sich aber unterhalb der Trommel. D.h., vor dem Heizschritt ist Waschflüssigkeit in den Laugenbehälter eingelassen worden, wobei sie die sich in der Trommel befindende Wäsche durchfeuchtet hat. Die Wäsche hat Waschflüssigkeit aufgenommen, es befindet sich aber keine freie Flotte in der Trommel. Während des Heizschritts wird die Waschflüssigkeit mittels des Heizkörpers auf die von dem Waschprogramm vorgegebene Wäschetemperatur aufgeheizt. Bei eingeschaltetem Heizkörper stellt sich eine Temperaturschichtung ein, die dazu führt, dass nach einer Zeitdauer ein Mikrosieden an der Heizkörperoberfläche auftritt. Aufgrund der geringen Distanz bis zur Oberfläche gelingt es den Dampfblasen, bis dorthin bestehen zu bleiben, und sie treten als Dampf aus. Da Energie über das natürliche Ausbreitungsverhalten des Dampfes prinzipiell in die feuchte Wäsche übertragen werden kann, wird die Wäsche auf die durch die Anwahltemperatur vorgegebene Wäschetemperatur erwärmt. Nach Erreichen der vorgegebenen Wäschetemperatur oder einer für den Heizschritt vorbestimmten Heiz-Zeitdauer wird das Heizen der Waschflüssigkeit beendet. Nach dem Heizschritt wird der Nachwaschschritt durchgeführt.During the heating step, the washing liquid covers the radiator disposed in the tub, but is below the drum. That is, before the heating step washing liquid has been introduced into the tub, wherein it has moistened the laundry located in the drum. The laundry has taken up washing liquid, but there is no free liquor in the drum. During the heating step, the washing liquid is heated by means of the radiator to the predetermined by the washing program wash temperature. When the radiator is turned on, a temperature stratification sets in, which leads to microsolation occurring on the radiator surface after a period of time. Because of the short distance to the surface, the vapor bubbles manage to persist there, and they exit as vapor. Since energy can be transmitted via the natural propagation behavior of the steam in principle into the wet laundry, the laundry is heated to the predetermined by the selection temperature wash temperature. After reaching the predetermined laundry temperature or a predetermined heating step for the heating step, the heating of the washing liquid is stopped. After the heating step, the post-washing step is carried out.
In Abhängigkeit von der Anwahltemperatur wird Waschflüssigkeit aus dem unteren Bereich des Laugenbehälters in den oberen Bereich des Laugenbehälters gefördert. Der untere Bereich des Laugenbehälters ist im Sinne der vorliegenden Erfindung der Sumpf der Waschmaschine. Der Sumpf ist der untere Bereich der Waschmaschine, in dem sich die in den Laugenbehälter eingelassene Waschflüssigkeit aufgrund der Schwerkraft ansammelt und sich unterhalb der Trommel befindet. Der obere Bereich des Laugenbehälters ist im Sinne der vorliegenden Erfindung der Bereich des Laugenbehälters, der sich über dem Sumpf befindet. Mittels der Aktivierung der Umfluteinrichtung wird die sich im Sumpf befindende Waschflüssigkeit in den oberen Bereich des Laugenbehälters gefördert und somit dem Sumpf entzogen.Depending on the selection temperature, washing liquid is conveyed from the lower region of the tub into the upper region of the tub. The lower portion of the tub is within the meaning of the present invention, the bottom of the washing machine. The sump is the lower part of the washing machine, in which the washing liquid introduced into the tub accumulates by gravity and is located below the drum. The upper portion of the tub in the context of the present invention, the area of the tub, which is located above the bottom. By means of the activation of the circulating device, the washing liquid located in the sump is conveyed into the upper region of the suds container and thus withdrawn from the sump.
In einer bevorzugten Ausführungsform wird die Umfluteinrichtung während des Nachwaschschritts aktiviert, wenn die Anwahltemperatur kleiner oder gleich einer Grenztemperatur ist. Die Relation von der Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit zur Anwahltemperatur spielt insbesondere eine Rolle bei der Entscheidung, ob die Aktivierung der Umfluteinrichtung sinnvoll ist oder nicht. Die Grenztemperatur hängt daher bevorzugt von der theoretisch zu erwartenden oder während des Heizschritts gemessenen Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit ab.In a preferred embodiment, the Umfluteinrichtung is activated during the Nachwaschschritts if the selection temperature is less than or equal to a threshold temperature. The relation of the temperature of the washing liquid at the lower region of the tub to the selection temperature plays a particular role in the decision as to whether the activation of the circulating device makes sense or not. The limit temperature therefore preferably depends on the temperature theoretically expected or measured during the heating step of the washing liquid located in the lower region of the tub.
Vorzugsweise ist die Grenztemperatur gleich der Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit oder bevorzugterweise bis zu 5°C höher. Vorzugsweise wird die Grenztemperatur in einem Temperaturbereich gewählt, welche zwischen der Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit und einer um 5°C höheren Temperatur liegt. Beispielsweise beträgt die Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit etwa 45°C. Bei Waschprogrammen mit einer Anwahltemperatur bis zu 45°C ist es dann effizient, die Umfluteinrichtung zu aktivieren, weil die durch die Umfluteinrichtung geförderte Flüssigkeit einerseits zur Erhöhung der Wäschetemperatur beitragen kann und anderseits für eine bessere Durchmischung von Wäsche und Waschflüssigkeit gesorgt wird. Wenn die Anwahltemperatur gleich der oder bis zu 5°C höher als die Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit ist, also im obigen Beispiel bis 50°C, dann wird zwar wahrscheinlich die Wäschetemperatur nicht erhöht sondern eher geringfügig verringert, aber eine Erhöhung der Waschflüssigkeit in der Wäsche durch Aktivierung der Umfluteinrichtung kann zur Verbesserung der Waschwirkung beitragen.The limit temperature is preferably equal to the temperature of the washing liquid located in the lower region of the lye container, or preferably up to 5 ° C. higher. The limit temperature is preferably selected in a temperature range which is between the temperature of the washing liquid located in the lower region of the lye container and a temperature which is higher by 5 ° C. For example, the temperature of the washing liquid located in the lower region of the tub is about 45.degree. In washing programs with a selection temperature up to 45 ° C, it is then efficient to activate the Umfluteinrichtung because the funded by the Umfluteinrichtung fluid can on the one hand contribute to increase the laundry temperature and on the other hand ensures better mixing of laundry and washing liquid. If the selection temperature is equal to or up to 5 ° C higher than the temperature of the washing liquid located in the lower part of the tub, so in the above example to 50 ° C, then probably the temperature of the laundry is not increased but rather slightly reduced, but one Increasing the washing liquid in the laundry by activating the flooding device can contribute to the improvement of the washing effect.
Die Grenztemperatur liegt vorzugsweise zwischen 40°C und 60°C, bevorzugter zwischen 45°C und 50°C. Je nach Waschmaschinentyp und beispielsweise den Abmessungen des Heizkörpers und den Abmessungen des unteren Bereichs des Laugenbehälters und der eingestellten Anwahltemperatur kann die Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit am Ende des Heizschritts variieren. Bei einer Haushaltwaschmaschine, bei der sich am Ende des Heizschritts 1,0 bis 2,0 Liter oder durchschnittlich ca. 1,5 Liter Waschflüssigkeit im unteren Bereich des Laugenbehälters befinden, liegt die Temperatur der sich im unteren Bereich des Laugenbehälters befindenden Waschflüssigkeit im Bereich von 35 bis 55 °C, eher im Bereich von 40 bis 45°C.The limit temperature is preferably between 40 ° C and 60 ° C, more preferably between 45 ° C and 50 ° C. Depending on the washing machine type and, for example, the dimensions of the radiator and the dimensions of the lower portion of the tub and the set temperature selection, the temperature of the washing liquid located in the lower part of the tub can vary at the end of the heating step. In a household washing machine, in which 1.0 to 2.0 liters or an average of about 1.5 liters of washing liquid are at the bottom of the tub at the end of the heating step, the temperature of the washing liquid located in the lower region of the tub is in the range of 35 to 55 ° C, more in the range of 40 to 45 ° C.
In einer bevorzugten Ausführungsform wird die Umfluteinrichtung nach Aktivierung in Abhängigkeit des Waschflüssigkeitspegels und/oder zeitabhängig deaktiviert. Wenn aus dem Sumpf keine Waschflüssigkeit mehr gefördert werden kann, wird die Umfluteinrichtung vorzugsweise deaktiviert, damit sie keinen Schaden nimmt. Hierzu kann das Verfahren eine zeitliche Steuerung der Umfluteinrichtung und/oder eine waschflüssigkeitspegelabhängige Regelung zur Bestimmung des Zeitpunkts der Deaktivierung der Umfluteinrichtung aufweisen. Beispielsweise kann das Verfahren nach Aktivierung der Umfluteinrichtung nach einer vorbestimmten Deaktivierungs-Zeitdauer deaktiviert werden. Alternativ oder zusätzlich zur zeitlichen Steuerung der Deaktivierung der Umfluteinrichtung kann die Umfluteinrichtung auch in Abhängigkeit des Waschflüssigkeitspegels in dem unteren Bereich des Laugenbehälters deaktiviert werden, der beispielsweise mittels Sensormitteln ermittelt werden kann.In a preferred embodiment, the flooding device is deactivated after activation as a function of the washing liquid level and / or time-dependent. If no washing liquid can be pumped out of the sump, the circulating device is preferably deactivated so that it does not become damaged. For this purpose, the method may include a time control of the circulating device and / or a control fluid level-dependent control for determining the time of deactivation of the circulating device. For example, the method may be deactivated after activation of the flooding device after a predetermined deactivation period. Alternatively, or in addition to the timing of the deactivation of the Umfluteinrichtung the Umfluteinrichtung can also be deactivated depending on the washing liquid level in the lower portion of the tub, which can be determined for example by means of sensor means.
Vorzugsweise wird die Umfluteinrichtung in Abhängigkeit des Waschflüssigkeitspegels deaktiviert, wenn die von der Umfluteinrichtung zu fördernde Waschflüssigkeitsmenge unterhalb eines vorbestimmten Waschflüssigkeitsmengen-Schwellenwerts liegt. Ob die zu fördernde Waschflüssigkeitsmenge unterhalb des vorbestimmten Waschflüssigkeitsmengen-Schwellenwerts liegt, hängt von dem Waschflüssigkeitspegel in dem unteren Bereich des Laugenbehälters ab und kann beispielsweise mittels eines Sensors ermittelt werden. Der vorbestimmte Waschflüssigkeitsmengen-Schwellenwert ist bevorzugt derart gewählt, dass die Umfluteinrichtung während der Förderung aufgrund einer zu geringen zur Verfügung stehenden Waschflüssigkeitsmenge der Waschflüssigkeit keinen Schaden nimmt und/oder ihr Betrieb ineffektiv ist.Preferably, the flooding device is deactivated as a function of the washing liquid level when the amount of washing liquid to be conveyed by the flooding device is below a predetermined washing liquid quantity threshold value. Whether the amount of scrubbing liquid to be conveyed is below the predetermined scrubbing liquid amount threshold value depends on the level of scrubbing liquid in the lower area of the scrubber and can be determined, for example, by means of a sensor. The predetermined washing liquid quantity threshold value is preferably chosen such that the circulatory device is not damaged during the delivery due to an insufficient amount of washing liquid available to the washing liquid and / or its operation is ineffective.
In einer bevorzugten Ausführungsform wird die Umfluteinrichtung nach Deaktivierung erneut aktiviert, wenn der Waschflüssigkeitspegel in dem unteren Bereich des Laugenbehälters oberhalb eines vorbestimmten Waschflüssigkeitspegel-Schwellenwerts liegt. In diesem Fall kann die Umfluteinrichtung intervallmäßig betrieben werden. Ob dies sinnvoll ist, kann beispielsweise mittels Sensoren ermittelt werden, die die Wäschetemperatur und die Waschflüssigkeitstemperatur in dem unteren Bereich des Laugenbehälters messen. Wenn das Verhältnis von Wäschetemperatur und Waschflüssigkeitstemperatur in dem unteren Bereich des Laugenbehälters ergibt, dass eine Aktivierung der Umfluteinrichtung zur Effizienz des Verfahrens beiträgt, wird die Umfluteinrichtung aktiviert, andernfalls nicht.In a preferred embodiment, after deactivation, the flooding device is reactivated when the wash liquid level in the lower portion of the tub is above a predetermined wash liquid level threshold. In this case, the Umfluteinrichtung can be operated at intervals. Whether this makes sense can be determined for example by means of sensors which measure the washing temperature and the washing liquid temperature in the lower region of the tub. When the ratio of wash temperature and wash liquid temperature in the lower Area of the tub results that activation of the Umfluteinrichtung contributes to the efficiency of the process, the Umfluteinrichtung is activated, otherwise not.
Vorzugsweise ist das Verfahren derart ausgestaltet, dass im Falle einer Aktivierung der Umfluteinrichtung die Umfluteinrichtung zu Beginn des Nachwaschschritts, d.h. nach dem Ende des Heizschritts, aktiviert wird. Dadurch kann die zusätzliche Waschwirkung während des Nachwaschschritts optimal ausgenutzt werden. Die Umfluteinrichtung wird während des Nachwaschschritts deaktiviert, wenn der Umfluteinrichtung nicht mehr genügend zu fördernde Waschflüssigkeit zur Verfügung steht und/oder wenn eine vorbestimmte Aktivierungs-Zeitdauer abgelaufen ist. Bevorzugt wird die Umfluteinrichtung während des Nachwaschschritts im Falle einer Aktivierung einmal aktiviert und deaktiviert und der Nachwaschschritt wird nach des einmaligen Betriebs der Umfluteinrichtung fortgeführt. Eine einmalige Aktivierung der Umfluteinrichtung ist im Falle einer zur Aktivierung der Umfluteinrichtung geeigneten Anwahltemperatur ausreichend, um auf eine einfache Weise eine verbesserte Effizienz des Waschverfahrens zu erreichen.Preferably, the method is such that, in the case of activation of the flooding device, the flooding device at the beginning of the post-washing step, i. after the end of the heating step, is activated. As a result, the additional washing effect during the Nachwaschschritts be optimally utilized. The circulating device is deactivated during the Nachwaschschritts when the circulating device is no longer sufficient to be pumped washing liquid available and / or when a predetermined activation period has expired. In the case of an activation, the circulating device is preferably activated and deactivated once during the subsequent washing step, and the subsequent washing step is continued after the single-use operation of the circulating device. A one-time activation of the flooding device is sufficient in the case of a selection temperature suitable for activating the flooding device, in order to achieve an improved efficiency of the washing method in a simple manner.
Im Falle einer mehrfachen Aktivierung und Deaktivierung der Umfluteinrichtung kann zwar eine verbesserte Durchmischung von Wäsche und Waschflüssigkeit erreicht werden, dem steht allerdings ein erhöhter verfahrenstechnischer und bautechnischer Aufwand entgegen. Die Vorteile und Nachteile einer einmaligen Aktivierung und Deaktivierung der Umfluteinrichtung sind daher gegenüber einer mehrmaligen Aktivierung und Deaktivierung der Umfluteinrichtung insbesondere in Abhängigkeit des vom Waschmaschinennutzer gewählten Waschprogramms abzuwägen.In the case of a multiple activation and deactivation of the circulating device, although an improved mixing of laundry and washing liquid can be achieved, however, this is precluded by an increased procedural and constructional effort. The advantages and disadvantages of a single activation and deactivation of the circulating device are therefore to be weighed against a repeated activation and deactivation of the circulating device, in particular depending on the washing program selected by the washing machine user.
In einer bevorzugten Ausführungsform wird eine zum Betreiben des Heizkörpers während des Heizschritts aufzuwendende Energiemenge derart eingestellt, dass die Wäschetemperatur der Anwahltemperatur entspricht. Mit Auswählen der Anwahltemperatur stellt der Waschmaschinennutzer die Soll-Temperatur zum Waschen der Wäsche in dem Nachwaschschritt ein. Die Wäschetemperatur, d.h. die Ist-Temperatur während des Nachwaschschritts, hängt im Wesentlichen von 3 Eingangsgrößen ab: 1. der Anwahltemperatur, 2. der Waschflüssigkeitsmenge und 3. der Mischtemperatur von Waschflüssigkeit und Wäsche. Die Mischung von Waschflüssigkeit und Wäsche entsteht dadurch, dass die Wäsche die vor dem Heizschritt eingefüllte Waschflüssigkeit aufnimmt. Da die eingefüllte Waschflüssigkeitsmenge jedoch derart eingestellt wird, dass keine freie Flotte in der Trommel vorhanden ist, befindet sich die aufzuheizende Waschflüssigkeitsmenge im unteren Bereich des Laugenbehälters, sodass sie den Heizkörper bedeckt, sich aber unterhalb der Trommel befindet. Mittels Auswählen der Anwahltemperatur wird die zu erreichende Wäschetemperatur vorgegeben. In Abhängigkeit von der vor dem Heizschritt eingefüllten Waschflüssigkeitsmenge und der Mischtemperatur von Wäsche und Waschflüssigkeit wird nun die während des Heizschritts benötigte Energiemenge derart eingestellt, dass die Wäschetemperatur der Anwahltemperatur entspricht.In a preferred embodiment, an amount of energy expended for operating the radiator during the heating step is adjusted such that the laundry temperature corresponds to the selection temperature. Upon selecting the dial temperature, the washing machine user sets the target temperature for washing the laundry in the post-washing step. The washing temperature, ie the actual temperature during the subsequent washing step, depends essentially on 3 input variables: 1. the selection temperature, 2. the amount of washing liquid and 3. the mixing temperature of washing liquid and laundry. The mixture of washing liquid and laundry results from the fact that the laundry absorbs the washing liquid introduced before the heating step. However, since the filled amount of the washing liquid is adjusted so that there is no free liquor in the drum, the amount of washing liquid to be heated is in the lower portion of the tub, so that it covers the radiator but is below the drum. Selecting the selection temperature sets the temperature to be reached. Depending on the amount of washing liquid filled before the heating step and the mixing temperature of the laundry and Washing liquid is now set the amount of energy required during the heating step such that the wash temperature corresponds to the selection temperature.
Die Erfindung betrifft weiterhin eine Waschmaschine mit einem Laugenbehälter zur Aufnahme von Waschflüssigkeit, einer im Laugenbehälter drehbar gelagerten Trommel zur Aufnahme von zu behandelnder Wäsche, einem Heizkörper, einer Umfluteinrichtung und einer Regeleinrichtung zum Steuern eines Waschprogramms. Die Regeleinrichtung ist dazu eingerichtet, die Waschmaschine während der Durchführung des vorstehend beschriebenen Verfahrens zu betreiben. Um ein energieeffizientes Verfahren bereitzustellen, ist die Regeleinrichtung insbesondere dafür eingerichtet, die für das ausgewählte Waschprogramm benötigte Waschflüssigkeitsmenge derart einzustellen, dass keine freie Flotte in der Trommel vorhanden ist, dass der Heizkörper während des Heizschritts Dampf erzeugt, und dass die Umfluteinrichtung in Abhängigkeit der Anwahltemperatur aktiviert wird. Vorzugweise ist die Regeleinrichtung dafür eingerichtet, die Umfluteinrichtung im Falle einer Aktivierung zeitabhängig und/oder waschflüssigkeitspegelabhängig zu deaktivieren. Weiterhin kann die Regeleinrichtung vorzugsweise die zum Betreiben des Heizkörpers aufzuwendende Energiemenge ermitteln und einregeln.The invention further relates to a washing machine with a tub for receiving washing liquid, a rotatably mounted in the tub drum for receiving laundry to be treated, a radiator, a Umfluteinrichtung and a control device for controlling a washing program. The control device is adapted to operate the washing machine during the implementation of the method described above. In order to provide an energy-efficient method, the control device is in particular configured to adjust the amount of washing liquid required for the selected wash program such that no free liquor is present in the drum, that the heating element generates steam during the heating step, and that the circulating device depends on the selection temperature is activated. Preferably, the control device is adapted to disable the Umfluteinrichtung in the case of activation time-dependent and / or washing liquid level dependent. Furthermore, the control device can preferably determine and adjust the amount of energy expended for operating the radiator.
