Definitions
- the invention relates to a program-controlled washing machine with a rotating drum in a tub and a detergent dispenser, which is divided into several dispenser compartments for receiving the detergent and care products and a water softener and the fresh water is supplied to the tub via the dispenser.
- a washing machine of this type is known from DE-A 37 15 832.
- the water softener is rinsed into the tub at the same time as the detergent.
- a washing machine with a tub for receiving a laundry drum which is connected by an overflow to a preheater and softener boiler.
- the tub and the softener boiler each have a direct feed line to a detergent or softener feed hopper.
- a softening agent is introduced by hand through the relevant funnel in the water softener. After opening a fresh water supply valve assigned to the softening boiler, the softened water is conveyed via the overflow into the tub.
- the washing water is softened in a special container and thus outside of the washing tub receiving the washing drum and then fed to the washing tub.
- This softening process not only requires an additional container that makes the washing machine more expensive, but also lengthens due to the additional manual handling and preparation of the Wash water outside the tub also significantly increases the total wash time.
- the invention has for its object to simplify the softening of the washing water in a drum washing machine in terms of handling and improve its effectiveness, so that the active substances of both the softening agent and the detergent are fully effective and thus better utilized.
- the solution to this problem according to the invention is that first the water softener and only then the detergent with the incoming fresh water is flushed into the tub, the washing detergent being carried out with a certain time delay after the water softener flushing process and the time delay approximately Is 5 minutes.
- the proposed softening process also considerably reduces the environmental impact, since the addition of the water softening agent can be reduced by about 20% due to this handling with equally good results.
- the water softener can also first be flushed in with a smaller amount of water than the amount of water required for the washing process, for example 2 to 5 liters. This further improves the activation of the detergent subsequently washed in.
- the washing machine 1 shown in FIG. 1 has an integrated drawer-like induction device 2 for a wide variety of laundry treatment agents, such as water softeners, detergents, fabric softeners.
- the induction device 2 is in the illustrated embodiment in three treatment agent chambers 4, 5 u. 6 divided.
- the water softener is filled into the treatment agent chamber 4 and the detergent into the chamber 5.
- the fabric softener can be introduced into the chamber 6.
- the washing machine 1 has a tub with a washing drum running around it, which can be loaded with laundry via a front loading opening closed by a porthole window 3.

- Line 7 shows the course of water softening when the water softener and the detergent are flushed in at the same time (prior art).
- Line 8 shows the course of water softening if the water softener is washed in first and then the detergent. From this line it can be seen that the water hardness of the washing water is reduced or bound very quickly when the water softening agent is separated and brought in earlier and that the subsequent washing or addition of detergent, which occurs at time P, is carried out with completely softened washing water.
- the water softener is filled in the treatment agent chamber 4 and the detergent in the chamber 5.
- the water inlet (not shown) is opened, a certain partial amount, preferably 2 to 5 liters, of the total fresh water inlet is first let in via the chamber 4 and the water softener is thus flushed into the tub.
- the fresh water supply is opened again until the required washing level is reached.
- the laundry drum can also be set in a reversing movement in order to achieve a good distribution of the water softening agent in the wash water.
- the further water supply takes place via the chamber 5 and rinses the detergent located there into the tub.
- the detergent can also be rinsed in immediately after the water softener has been rinsed in. This could be useful if the overall washing program should not be extended.
- a further possible embodiment is that the water softener is first rinsed out of the chamber 4 of the induction device 2, the entire amount of water required being fed to the washing drum at the same time. After a certain period of time, e.g. B. up to 5 minutes, during which the water softener has been dissolved or well distributed in the wash water and has fully developed its effect, part of this wash liquor is pumped up to the chamber 5 of the dispenser 2, in which the detergent is located, and this Chamber rinsed out.

- Another embodiment is characterized in that the inflowing fresh water first enters the chamber 4 of the induction device 2, in which the water softener is located. From this chamber, the water is passed into the chamber 5 with the detergent.
- a further chamber can expediently be connected between the two chambers. This will ensure good mixing of the Water softener and the fresh water as well as the solution or dispersion of all softening substances in the flushed fresh water.
- the program control device of the washing machine has corresponding switching steps for controlling the execution options described.
Description
Die Erfindung betrifft eine programmgesteuerte Waschmaschine mit einer in einem Laugenbehälter umlaufenden Wäschetrommel und einer Waschmittel-Einspülvorrichtung, die in mehrere Einspülkammern zur Aufnahme der Wasch- und Pflegemittel sowie eines Wasserenthärtungsmittels unterteilt ist und die Frischwasserzufuhr zum Laugenbehälter über die Einspülvorrichtung erfolgt.The invention relates to a program-controlled washing machine with a rotating drum in a tub and a detergent dispenser, which is divided into several dispenser compartments for receiving the detergent and care products and a water softener and the fresh water is supplied to the tub via the dispenser.
Eine Waschmaschine dieser Art ist aus der DE-A 37 15 832 bekannt. Bei dieser Waschmaschine wird das Wasserenthärtungsmittel gleichzeitg mit dem Waschmittel in den Laugenbehälter eingespült.A washing machine of this type is known from DE-A 37 15 832. In this washing machine, the water softener is rinsed into the tub at the same time as the detergent.
Weiterhin ist aus der FR-A 1 156 788 eine Waschmaschine mit einem Laugenbehälter zur Aufnahme einer Wäschetrommel bekannt, der durch einen Überlauf mit einem Vorwärmer- und Enthärteboiler Verbunden ist. Der Laugenbehälter und der Enthärteboiler besitzen je eine direkte Zuleitung zu einem Wasch- bzw. Enthärtemittel-Eingabetrichter. Zum Enthärten des Wassers für den Hauptwaschgang wird ein Enthärtemittel von Hand durch den betreffenden Eingabetrichter in dem mit Wasser gefüllten Enthärteboiler eingebracht. Nach Öffnen eins dem Enthärteboiler zugeordneten Frischwasserzulaufventils wird das enthärtete Wasser über den Überlauf in den Laugenbehälter befördert. Bei dieser Waschmaschine wird das Waschwasser in einem speziellen Behälter und damit außerhalb des die Wäschetrommel aufnehmenden Laugenbehälters enthärtet und danach dem Laugenbehälter zugeführt. Dieses Enthärtungsverfahren erfordert nicht nur einen die Waschmaschine verteuernden zusätzlichen Behälter sondern verlängert aufgrund der zusätzlichen manuellen Handhabung sowie Aufbereitung des Waschwassers außerhalb des Laugenbehälters auch die Gesamtwaschdauer erheblich.Furthermore, from FR-A 1 156 788 a washing machine with a tub for receiving a laundry drum is known, which is connected by an overflow to a preheater and softener boiler. The tub and the softener boiler each have a direct feed line to a detergent or softener feed hopper. To soften the water for the main wash cycle, a softening agent is introduced by hand through the relevant funnel in the water softener. After opening a fresh water supply valve assigned to the softening boiler, the softened water is conveyed via the overflow into the tub. In this washing machine, the washing water is softened in a special container and thus outside of the washing tub receiving the washing drum and then fed to the washing tub. This softening process not only requires an additional container that makes the washing machine more expensive, but also lengthens due to the additional manual handling and preparation of the Wash water outside the tub also significantly increases the total wash time.
Ausgehend von diesem Stand der Technik liegt der Erfindung die Aufgabe zugrunde, das Enthärten des Waschwassers in einer Trommelwaschmaschine handhabungsmäßig zu vereinfachen und in der Wirkung zu verbessern, so daß die aktiven Substanzen sowohl des Enthärtungsmittels als auch des Waschmittels voll wirksam und damit besser ausgenützt werden.Based on this prior art, the invention has for its object to simplify the softening of the washing water in a drum washing machine in terms of handling and improve its effectiveness, so that the active substances of both the softening agent and the detergent are fully effective and thus better utilized.
Die Lösung dieser Aufgabe gemäß der Erfindung besteht darin, daß zuerst das Wasserenthärtungsmittel und danach erst das Waschmittel mit dem zulaufenden Frischwasser in den Laugenbehälter eingespült wird, wobei das Einspülen des Waschmittels mit einer gewissen Zeitverzögerung nach dem Wasserenthärtungsmittel-Einspülvorgang durchgeführt wird und die Zeitverzögerung in etwa 5 Minuten beträgt.The solution to this problem according to the invention is that first the water softener and only then the detergent with the incoming fresh water is flushed into the tub, the washing detergent being carried out with a certain time delay after the water softener flushing process and the time delay approximately Is 5 minutes.
Durch diese Maßnahme wird erreicht, daß das Wasserenthärtungsmittel unmittelbar in den Laugenbehälter eingespült und damit gut gelöst bzw. in der eingespülten Wassermenge gut verteilt wird, so daß die Härtebildner im Waschwasser bereits vorab gebunden sind, bevor das Waschmittel zugeführt bzw. in die Wäschetrommel eingespült wird. Die Folge davon ist ein wesentlich besseres Reinigungsergebnis bei dem betreffenden Waschgut bei Schonung der Wäsche und der Waschmaschine. Dadurch, daß das Einspülen des Waschmittels erst mit einer gewissen Zeitverzögerung nach dem Einspülen des Wasserenthärtungsmittels vorgenommen wird, wobei eine solche Zeitverzögerung bis zu 5 Minuten betragen kann, wird eine besonders gute Auflösung bzw. Verteilung des Wasserenthärtungsmittels im Waschwasser erreicht, da die Einspülung des Waschmittels bereits in das vollständig enthärtete Waschwasser erfolgt. Damit kann das Waschmittel mit der Einspülung auch sofort seine volle Waschkraft im Waschwasser entfalten.This measure ensures that the water softener is flushed directly into the tub and thus well dissolved or well distributed in the amount of water that is flushed in, so that the hardening agents in the wash water are already bound in advance before the detergent is added or flushed into the washing drum . The result of this is a much better cleaning result for the laundry in question while protecting the laundry and the washing machine. Because the detergent is only rinsed in with a certain time delay after the water softening agent has been rinsed in, such a time delay of up to 5 minutes being possible, a particularly good dissolution or distribution of the water softening agent in the washing water is achieved since the detergent is rinsed in already in the fully softened wash water. So that the detergent with the detergent, you can immediately develop your full washing power in the wash water.
Des weiteren wird durch das vorgeschlagene Enthärtungsverfahren auch eine erhebliche Umweltentlastung erreicht, da aufgrund dieser Handhabung bei gleichguten Ergebnissen die Zugabe des Wasserenthärtungsmittels um etwa 20 % verringert werden kann.Furthermore, the proposed softening process also considerably reduces the environmental impact, since the addition of the water softening agent can be reduced by about 20% due to this handling with equally good results.
Das Wasserenthärtungsmittel kann zunächst auch mit einer gegenüber der für den Waschvorgang erforderlichen Wassermenge geringeren Wassermenge, von beispielsweise 2 bis 5 Liter, eingespült werden. Dadurch wird die Aktivierung des nachfolgend eingespülten Waschmittels weiter verbessert.The water softener can also first be flushed in with a smaller amount of water than the amount of water required for the washing process, for example 2 to 5 liters. This further improves the activation of the detergent subsequently washed in.
Weitere vorteilhafte Maßnahmen sind in der Beschreibung des Anmeldungsgegenstandes enthalten.Further advantageous measures are contained in the description of the subject of the application.
DIe Erfindung wird nachfolgend anhand von zwei zeichnerischen Darstellungen näher beschrieben und noch weiter verdeutlicht.The invention is described in more detail below with reference to two graphic representations and made even clearer.
Es zeigen:
- Fig. 1
- eine Waschmaschine mit einer als Schublade ausgebildeten Einspülvorrichtung für die Wäschebehandlungsmittel,
- Fig. 2
- den Wasserenthärtungsverlauf bei der bisherigen Einspülungs-Methode und bei der Zwei-Stufen-Einspülung nach der Erfindung.
- Fig. 1
- a washing machine with a washing device designed as a drawer for the laundry treatment agents,
- Fig. 2
- the course of water softening in the previous induction method and in the two-stage induction according to the invention.
Die in Fig. 1 dargestellte Waschmaschine 1 besitzt eine integrierte schubladenartige Einspülvorrichtung 2 für die verschiedensten Wäschebehandlungmittel, wie Wasserenthärtungsmittel, Waschmittel, Weichspülmittel. Die Einspülvorrichtung 2 ist beim dargestellten Ausführungsbeispiel in drei Behandlungsmittel-Kammern 4, 5 u. 6 aufgeteilt. In der Behandlungsmittel-Kammer 4 wird das Wasserenthärtungsmittel und in der Kammer 5 das Waschmittel eingefüllt. In die Kammer 6 kann, wenn im Waschprogramm vorgesehen, das Weichspülmittel eingegeben werden. Die Waschmaschine 1 hat einen Laugenbehälter mit einer darin umlaufenden Wäschetrommel, die über eine durch ein Bullaugentürfenster 3 verschlossene frontseitige Beschickungsöffnung mit Waschgut beladbar ist.The
Im Schaubild nach Fig. 2 steht die Y-Achse für die Wasserhärte und auf der X-Achse ist die Zeit für den Einspülvorgang der Wäschebehandlungsmittel aufgetragen. Die Linie 7 zeigt den Wasserenthärtungsverlauf, wenn das Wasserenthärtungsmittel und das Waschmittel gleichzeitig (Stand der Technik) eingespült werden. Linie 8 gibt den Wasserenthärtungsverlauf wieder, wenn zuerst das Wasserenthärtungsmittel und danach erst das Waschmittel eingespült werden. Aus dieser Linie wird ersichtlich, daß bei der vom Waschmittel getrennten und vorgezogenen Einspülung des Wasserenthärtungsmittels die Wasserhärte des Waschwassers sehr schnell herabgesetzt bzw. gebunden wird und daß die nachfolgende Einspülung bzw. Waschmittelzugabe, was beim Zeitpunkt P erfolgt, bei völlig enthärtetem Waschwasser vorgenommen wird. Mit weiterer Zuführung von Waschwasser steigt die Wasserhärte insgesamt wieder etwas an und stabilisiert sich nach einer gewissen Zeit unterhalb der Linie 7. Wie ein Vergleich der beiden Linien 7 und 8 deutlich zeigt, ist die Wirksamkeit des Wasserenthärtungsmittels bei der sogenannten Zwei-Stufen-Einspülung nach der Erfindung gegenüber der Einspülung nach dem Stand der Technik wesentlich gesteigert bei gleichzeitiger Einsparung von 20 % Wasserenthärtungsmittel. Dadurch, daß die Wasserhärte schon vor dem Waschen gebunden wird, kann sich das später zugeführte Waschmittel voll auf die Beseitigung des Schmutzes konzentrieren.In the diagram according to FIG. 2, the Y axis stands for the water hardness and the time for the washing-in process of the laundry treatment agents is plotted on the X axis. Line 7 shows the course of water softening when the water softener and the detergent are flushed in at the same time (prior art). Line 8 shows the course of water softening if the water softener is washed in first and then the detergent. From this line it can be seen that the water hardness of the washing water is reduced or bound very quickly when the water softening agent is separated and brought in earlier and that the subsequent washing or addition of detergent, which occurs at time P, is carried out with completely softened washing water. With further addition of washing water, the water hardness rises again somewhat and stabilizes below line 7 after a certain time. As a comparison of the two lines 7 and 8 clearly shows, the effectiveness of the water softener in the so-called two-stage flushing is less the invention compared to the flushing according to the prior art significantly increased while saving 20% water softener. Because the water hardness is bound before washing, the detergent added later can concentrate fully on removing the dirt.
Die sogenannte Zwei-Stufen-Einspülung nach der Erfindung kann nun wie folgt durchgeführt werden:The so-called two-stage flushing in accordance with the invention can now be carried out like be carried out as follows:
Wie bereits erwähnt, ist in der Behandlungsmittel-Kammer 4 das Wasserenthärtungsmittel und in der Kammer 5 das Waschmittel eingefüllt. Mit Öffnen des nicht dargestellten Wasserzulaufs wird eine bestimmte Teilmenge, vorzugsweise 2 bis 5 Liter, des insgesamt zulaufenden Frischwassers zuerst über die Kammer 4 eingelassen und damit das Wasserenthärtungsmittel in den Laugenbehälter eingespült. Nach einer kurzen Zeitspanne wird der Frischwasserzulauf bis zum Erreichen des erforderlichen Waschniveaus erneut geöffnet. Gleichzeitig mit dem Zulauf oder erst nach dem Zulauf kann die Wäschetrommel zusätzlich in eine reversierende Bewegung gesetzt werden, um eine gute Verteilung des Wasserenthärtungsmittels im Waschwasser zu erzielen. Nach einer Zeitspanne von bis zu 5 Minuten erfolgt der weitere Wasserzulauf über die Kammer 5 und spült das dort befindliche Waschmittel in den Laugenbehälter ein. Das Einspülen des Waschmittels kann auch unmittelbar nach dem Einspülen des Wasserenthärtungsmittels durchgeführt werden. Dies könnte zweckmäßig sein, wenn das Gesamtwaschprogramm zeitlich nicht verlängert werden soll.As already mentioned, the water softener is filled in the treatment agent chamber 4 and the detergent in the chamber 5. When the water inlet (not shown) is opened, a certain partial amount, preferably 2 to 5 liters, of the total fresh water inlet is first let in via the chamber 4 and the water softener is thus flushed into the tub. After a short period of time, the fresh water supply is opened again until the required washing level is reached. Simultaneously with the inflow or only after the inflow, the laundry drum can also be set in a reversing movement in order to achieve a good distribution of the water softening agent in the wash water. After a period of up to 5 minutes, the further water supply takes place via the chamber 5 and rinses the detergent located there into the tub. The detergent can also be rinsed in immediately after the water softener has been rinsed in. This could be useful if the overall washing program should not be extended.
Eine weitere Ausführungsmöglichkeit besteht darin, daß zunächst das Wasserenthärtungsmittel aus der Kammer 4 der Einspülvorrichtung 2 ausgespült wird, wobei gleichzeitig die gesamte erforderliche Wassermenge der Wäschetrommel zugeführt wird. Nach Ablauf einer bestimmten Zeitspanne, von z. B. bis zu 5 Minuten, während der das Wasserenthärtungsmittel gelöst bzw. im Waschwasser gut verteilt worden ist, und seine Wirkung voll entfaltet hat, wird ein Teil dieser Waschlauge zur Kammer 5 der Einspülvorrichtung 2, in welcher sich das Waschmittel befindet, hochgepumpt und diese Kammer ausgespült.A further possible embodiment is that the water softener is first rinsed out of the chamber 4 of the
Ein anderes Ausführungsbeispiel zeichnet sich dadurch aus, daß das zufließende Frischwasser zuerst in die Kammer 4 der Einspülvorrichtung 2 gelangt, in welcher sich das Wasserenthärtungsmittel befindet. Von dieser Kammer aus wird das Wasser in die Kammer 5 mit dem Waschmittel geleitet. Zwischen den beiden Kammern kann zweckmäßig noch eine weitere Kammer geschaltet sein. Dadurch wird eine gute Vermischung des Wasserenthärtungsmittels und des Frischwassers sowie die Lösung bzw. Dispergierung sämtlicher Enthärtersubstanzen im eingespülten Frischwasser erreicht.Another embodiment is characterized in that the inflowing fresh water first enters the chamber 4 of the
Ohne darauf näher eingehen zu wollen, muß noch erwähnt werden, daß die Programmsteuereinrichtung der Waschmaschine zur Steuerung dieser beschriebenen Ausführungsmöglichkeiten entsprechende Schaltschritte aufweist.Without wishing to go into this in more detail, it must also be mentioned that the program control device of the washing machine has corresponding switching steps for controlling the execution options described.
