Description
Wasserführendes Haushaltgerät, insbesondere Waschmaschine Water-bearing household appliance, especially a washing machine
Die Erfindung betrifft ein wasserführendes Haushaltgerät, insbesondere Waschmaschine, das an eine erste Wasserzufuhrleitung für kaltes Wasser und eine zweite Wasserzufuhrleitung für heißes Wasser angeschlossen ist, wobei die Wasserzuführleitungen an eine Mischbatterie angeschlossen sind, aus der Wasser über eine Zuleitung in einen Laugenbehalter einfüllbar ist. Ein derartiges Haushaltgerät ist bereits aus der US 4 147 297 bekannt. Dort wird eine Waschmaschine beschrieben, die zwei Zuführungsleitungen umfasst, die jeweils an einen Kalt- bzw. einen Warmwasseranschluss angeschlossen sind. Die Zuführungsleitungen sind an eine Mischbatterie angeschlossen, die zwei Elektroventile umfasst. Je nach Öffnungszustand der Elektroventile wird heißes, warmes oder kaltes Wasser durch einen Zuführschlauch in einen Laugenbehalter der Waschmaschine eingelassen.The invention relates to a water-carrying household appliance, in particular a washing machine, which is connected to a first water supply line for cold water and a second water supply line for hot water, the water supply lines being connected to a mixer tap from which water can be filled into a tub through a supply line. Such a household appliance is already known from US 4 147 297. A washing machine is described there, which comprises two feed lines, each of which is connected to a cold or hot water connection. The feed lines are connected to a mixer tap that includes two solenoid valves. Depending on the opening state of the electrovalves, hot, warm or cold water is let into a washing machine tub through a feed hose.
Die bekannte Waschmaschine umfasst einen ersten Schalter zum Erfassen eines vorbestimmten Temperaturpegels des heißen Wassers. Der Benutzer der Waschmaschine kann wählen, ob er mit heißem oder nur mit warmem Wasser waschen möchte. Wenn er heißes Wasser auswählt, lässt ein Heißwasserventil solange ausschließlich heißes Wasser ein, wie ein bestimmter, vorgegebener Temperaturwert nicht überschritten wird. Wenn jedoch der Temperaturwert erreicht wird, wird der Schalter geschlossen. Dadurch betätigt er das Elektroventil, das zusätzlich kaltes Wasser in den Laugenbehalter einlaufen lässt. Wenn andererseits der Benutzer warmes Wasser für einen anderen Waschvorgang ausgewählt hat, betätigt er einen Bedienschalter. Auch in diesem Fall ist das Heißwasserventil zunächst allein geöffnet. Ein zweiter Schalter erfasst einen Temperaturpegel, der einer vorbestimmten Temperatur des warmen Wassers entspricht. Wenn dieser überschritten wird, wird ein zweiter Schalter geschlossen, so dass auch in diesem Fall zusätzlich kaltes Wasser in den Laugenbehalter einläuft.The known washing machine comprises a first switch for detecting a predetermined temperature level of the hot water. The user of the washing machine can choose whether he wants to wash with hot or only warm water. If he selects hot water, a hot water valve only lets in hot water as long as a certain, predetermined temperature value is not exceeded. However, when the temperature value is reached, the switch is closed. This actuates the electrovalve, which also allows cold water to enter the tub. On the other hand, when the user has selected warm water for another washing operation, he operates an operation switch. In this case too, the hot water valve is initially open on its own. A second switch detects a temperature level that corresponds to a predetermined temperature of the warm water. If this is exceeded, a second switch is closed, so that cold water also runs into the tub in this case.
Die bekannte Waschmaschine erlaubt damit einen Waschbetrieb auf zwei unterschiedlichen, vorgegebenen Temperaturen. Jedoch ist die Auswahl der Waschprogramme auf genau diese beiden Temperaturen beschränkt. Nachteilig an dem bekannten Verfahren ist, dass es nicht in jedem Fall sinnvoll ist, zunächst das heiße Wasser in den Laugenbehalter einzufüllen und anschließend das kalte Wasser entsprechend der gewünschten Temperatur zu ergänzen. Durch heißes Wasser kann es nämlich auch zur Verfestigung von Verschmutzungen in dem
Wäschestück kommen, die sich nachher nur schwer wieder entfernen lassen. Ein Beispiel hierfür sind Eiweißverbindungen, die durch Koagulieren des Eiweißes in dem Wäschestück erhärten. Das Koagulieren findet erst oberhalb einer bestimmten Temperatur statt, die gerade durch vorgeschaltetes Befüllen mit heißem Wasser überschritten wird.The known washing machine thus permits washing operation at two different, predetermined temperatures. However, the choice of washing programs is limited to exactly these two temperatures. A disadvantage of the known method is that it is not always sensible to first fill the hot water into the tub and then to add the cold water according to the desired temperature. Hot water can also cause dirt to solidify in the Items of laundry that are difficult to remove afterwards. An example of this are protein compounds which harden through coagulation of the protein in the laundry item. Coagulation only takes place above a certain temperature, which is just exceeded by filling with hot water beforehand.
Es ist die Aufgabe der Erfindung, ein wasserführendes Haushaltgerät derart weiterzubilden, dass es flexibel bei verschiedenen Temperaturen einsetzbar ist.It is the object of the invention to develop a water-carrying household appliance in such a way that it can be used flexibly at different temperatures.
Erfindungsgemäß wird diese Aufgabe bei einer Waschmaschine der eingangs genannten Art dadurch gelöst, dass die Mischbatterie in einer Regeleinrichtung integriert ist, durch die die Temperatur des in den Laugenbehalter einlaufenden Wassers regelbar ist.According to the invention, this object is achieved in a washing machine of the type mentioned at the outset in that the mixer tap is integrated in a control device by means of which the temperature of the water entering the tub can be regulated.
Durch die Erfindung ist es möglich, für jedes beliebige Programm eine vorgegebene Temperatur einzustellen, ohne dass diese von der Temperatur des zur Verfügung gestellten Warmwassers aus der Warmwasserleitung abhängig ist. Diese kann nämlich bei sehr verschiedenen Werten liegen, beispielsweise bei 40° C, aber auch bei 80° C und ist nicht vorher definierbar. Daher ist die Einspeisung von Zulaufwasser mit einer nicht exakt geregelten Zulauftemperatur in einem wasserführenden Haushaltgerät, also insbesondere in einem Geschirrspüler oder in einer Waschmaschine, nach dem Stand der Technik bei der Behandlung des zu reinigenden Geschirrs, besonders aber eines zu waschenden Wäschepostens, mit erheblichen Risiken verbunden.The invention makes it possible to set a predetermined temperature for any program without this being dependent on the temperature of the hot water made available from the hot water line. This can be at very different values, for example at 40 ° C, but also at 80 ° C and cannot be defined beforehand. Therefore, the feeding of feed water with a not exactly regulated feed temperature in a water-bearing household appliance, i.e. in particular in a dishwasher or in a washing machine, according to the state of the art in the treatment of the dishes to be cleaned, but especially of a laundry item to be washed, with considerable risks connected.
Erst gemäß der Erfindung kann die Zulauftemperatur des eingespeisten Wassers ständig angepasst und geändert werden. Über eine sowohl mit einer Kaltwasser- als auch mit einer Warmwasserleitung kommunizierende Mischbatterie wird stets nur Zulaufwasser mit einer geregelten Temperatur eingespeist. Auf diese Weise wird das Warmwasser in effektiver Weise ausgenutzt. Die Mischbatterie steht, da sie Teil einer Regeleinrichtung ist, in ständigem Datenaustausch mit einem Regler, so dass die für den jeweiligen Wasch- oder Reinigungsprozess erforderliche Temperatur exakt eingestellt wird. Das Einleiten des erfindungsgemäß richtig temperierten Wassers verkürzt den gesamten Waschprozess, da ein nachträgliches Mischen von kaltem und heißem Wasser nicht mehr notwendig ist.Only in accordance with the invention can the inlet temperature of the water fed in be continuously adapted and changed. Via a mixer tap that communicates with both a cold water and a hot water pipe, only feed water with a regulated temperature is fed in at all times. In this way, the hot water is used effectively. The mixer tap, since it is part of a control device, is in constant data exchange with a controller, so that the temperature required for the respective washing or cleaning process is set exactly. The introduction of the water which has the correct temperature according to the invention shortens the entire washing process, since a subsequent mixing of cold and hot water is no longer necessary.
Vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den Unteransprüchen.Advantageous developments of the invention result from the subclaims.
Mit Vorteil ist die Temperatur des in den Laugenbehalter einlaufenden Wassers je nach dem in dem Haushaltgerät ablaufenden Programm von einer Programmsteuereinheit vorgebbar. Programmindividuell wird eine bestimmte Temperatur des zulaufenden Wassers ausgewählt. Wenn die Regelung auf die Programmsteuereinheit des Haushaltgeräts zurückgreifen kann, wird in dem Reinigungs- oder Waschprozess kaum noch Elektroenergie benötigt. Dadurch
lässt sich auch die effektivste Temperatur in Verbindung mit einem dem Wasser zugesetzten Reinigungsmittel passend sowohl von Beginn des Reinigungs- oder Waschprozesses als auch im Gesamtprozess unter Ausnutzung von vorhandenem Warmwasser auswählen. Schon vor Beginn des Reinigungs- oder Waschprozesses kann eine genau bestimmte Temperatur des Zulaufwassers ausgewählt werden.The temperature of the water entering the tub can advantageously be predetermined by a program control unit, depending on the program running in the household appliance. A specific temperature of the incoming water is selected for each program. If the control can use the program control unit of the household appliance, then hardly any electrical energy is required in the cleaning or washing process. Thereby The most effective temperature can also be selected in conjunction with a detergent added to the water, both from the start of the cleaning or washing process and in the overall process using existing hot water. A precisely determined temperature of the feed water can be selected even before the cleaning or washing process begins.
In einer anderen Weiterbildung der Erfindung ist in dem Laugenbehalter eine Zusatzheizung vorhanden, durch die das aus der Zuleitung zugeführte Wasser auf eine noch höhere Temperatur aufheizbar ist. Diese muss nur dann eingesetzt werden, wenn ein Reinigungsvorgang durchgeführt werden soll, dessen Temperatur noch über der Temperatur des zugeführten heißen Wassers liegt.In another development of the invention, an additional heater is present in the tub, by means of which the water supplied from the feed line can be heated to an even higher temperature. This only has to be used if a cleaning process is to be carried out, the temperature of which is still above the temperature of the hot water supplied.
Als vorteilhaft erweist es sich darüber hinaus, wenn in die Programmsteuereinheit eine Fuzzy-Logik integriert ist. Dann ist die Programmsteuereinheit auch an sich ändernde Bedingungen innerhalb des Haushaltgeräts anpassbar. Durch die Erfindung wird ein Reinigungs- oder Waschprozess geschaffen, bei dem in erheblichem Maße elektrische Energie und zudem auch Zeit eingespart wird, da ein längerdauernder Heizvorgang entfällt. Nur noch gelegentlich wird es erforderlich sein, zusätzlich die Heizung in dem Laugenbehalter einzuschalten.It also proves to be advantageous if fuzzy logic is integrated in the program control unit. Then the program control unit can also be adapted to changing conditions within the household appliance. The invention creates a cleaning or washing process in which electrical energy and also time are saved to a considerable extent, since a longer heating process is eliminated. Only occasionally will it be necessary to additionally switch on the heating in the tub.
Darüber hinaus kann die in der Erfindung vorgesehene Mischbatterie auch in anderen Gebieten der Technik eingesetzt werden, beispielsweise in derIn addition, the mixer tap provided in the invention can also be used in other fields of technology, for example in
Lebensmittelindustrie und in der chemischen Industrie. In Verbindung mit einem technischen Zwecken dienenden Gebäude oder im Energiemanagement, z. B. der offenen LON (Local Operating System)-Technik kann die geregelte Mischbatterie zum Einsatz kommen. Dabei kann sie zentral gesteuert werden und eine Vielzahl von Prozessen, z. B. eine Spülung eines Rohrleitungssystems, um Legionellen oder andere Keime zu töten, genau und nachprüfbar durchführen. Durch dieFood industry and in the chemical industry. In connection with a technical building or in energy management, e.g. B. the open LON (Local Operating System) technology, the regulated mixer can be used. It can be controlled centrally and a variety of processes, e.g. B. flush a piping system to kill Legionella or other germs accurately and verifiably. Through the

Waschprozess ermöglicht, während im Unterschied zu der Erfindung eine herkömmliche Mischbatterie nur den einmal eingestellten Wert garantieren kann. Mittels der LON-Technik lässt sich hingegen vorsehen, dass die Waschmaschine erst dann in Betrieb geht, wenn die Steuerung abgefragt wurde, ob als Option auch warmes Wasser im Speicher bereit steht.Washing process enables, whereas in contrast to the invention, a conventional mixer tap can only guarantee the value set once. LON technology, on the other hand, can be used to ensure that the washing machine does not start up until the controller has been asked whether hot water is also available as an option.
Die Erfindung wird nachstehend an einem Ausführungsbeispiel anhand der Zeichnungen ausführlicher erläutert. Es zeigen: Fig. 1 schematisch eine Waschmaschine in einer Schnittansicht undThe invention is explained in more detail below using an exemplary embodiment with reference to the drawings. 1 schematically shows a washing machine in a sectional view and
Fig. 2 die Regelschaltung in schematischer Darstellung.Fig. 2 shows the control circuit in a schematic representation.
Eine Waschmaschine 1 (Fig. 1 ) weist in einem Gehäuse 2 einen Laugenbehalter 3 auf, in dem eine Wäschetrommel 4 drehbar über eine Welle 5 gelagert und über
eine nicht dargestellte Antriebseinheit antreibbar ist. Die Wäschetrommel 4 wird über eine (nicht dargestellte) Befüllöffnung mit einem Wäscheposten 7 beschickt. Über eine Wasserzufuhrleitung 8 wird heißes Wasser und über eine Wasserzufuhrleitung 9 wird kaltes Wasser einer Mischbatterie 10 zugeführt. Diese ist ausgangsseitig über eine Zuleitung 11 mit dem Laugenbehalter 3 verbunden.A washing machine 1 (FIG. 1) has a tub 3 in a housing 2, in which a washing drum 4 is rotatably mounted via a shaft 5 and via a drive unit, not shown, can be driven. The laundry drum 4 is loaded with a laundry item 7 via a filling opening (not shown). Hot water is supplied via a water supply line 8 and cold water is supplied to a mixer tap 10 via a water supply line 9. This is connected on the output side to the tub 3 via a feed line 11.
In den Laugenbehalter 3 wird entsprechend einer von einem Temperatursensor 12, der vorzugsweise in der Nähe des Bodens des Laugenbehälters 3 angebracht ist, gemessenen Temperatur der Wäschelauge über die Zuleitung 11 temperiertes Wasser eingeleitet. Dazu wird in einem dem Temperatursensor 12 zugeordneten Wandler 13 die Temperatur der Wäschelauge als Signalgröße x' gewonnen. Diese wird einem Subtrahierer 14 zugeführt, der die Differenz xd aus der Signalgröße x' und einer von einer Programmsteuereinheit 15 generierten Führungsgröße w bildet. Die Führungsgröße w ist die Größe, deren Wert, d. h. der Sollwert, die Aufgabengröße unter festgesetzten Bedingungen annehmen soll. Sie wird dem Subtrahierer 14 von außen, d. h. über die Programmsteuereinheit 15, zugeführt. Aus dem Differenzwert Xd erzeugt ein Regler 16 Signalgrößen VR-I, und yR2, aufgrund deren Magnetventile 17, 18 in der Mischbatterie 10 geöffnet oder geschlossen werden, um aus dem kalten und dem heißen Wasser aus den beiden Wasserzuführleitungen 8, 9 gemischtes Wasser der gewünschten Temperatur über die Zuleitung 11 dem Laugenbehalter 3 zuzuführen. Die Mischbatterie 10 fungiert somit als Stellglied in dem Regelkreis.In accordance with a temperature of the washing solution measured by a temperature sensor 12, which is preferably located in the vicinity of the bottom of the washing container 3, water is introduced into the washing container 3 via the feed line 11. For this purpose, the temperature of the washing solution is obtained as signal variable x 'in a converter 13 assigned to the temperature sensor 12. This is fed to a subtractor 14, which forms the difference x d from the signal variable x 'and a reference variable w generated by a program control unit 15. The command variable w is the variable whose value, ie the target value, the task variable should assume under specified conditions. It is fed to the subtractor 14 from the outside, ie via the program control unit 15. From the difference value X d , a controller 16 generates signal quantities VR-I, and y R2 , on the basis of which solenoid valves 17, 18 in the mixer tap 10 are opened or closed in order to mix water from the cold and hot water from the two water supply lines 8, 9 to supply the desired temperature to the tub 3 via the feed line 11. The mixer tap 10 thus acts as an actuator in the control loop.
Falls das aus der Mischbatterie 10 herausfließende Wasser noch nicht eine ausreichend hohe Temperatur aufweist, wird es über eine im Bodenbereich des Laugenbehälters 3 angeordnete, als Zusatzheizung dienende Heizung 19 auf die erforderliche hohe Temperatur gebracht. Auch die Heizung 19 steht hierbei mit der Programmsteuereinheit 15 über eine Signalleitung in Verbindung.If the water flowing out of the mixer tap 10 does not yet have a sufficiently high temperature, it is brought to the required high temperature via a heater 19 which is arranged in the bottom region of the tub 3 and serves as an additional heater. The heater 19 is also connected to the program control unit 15 via a signal line.
In der Programmsteuereinheit 15 ist vorzugsweise eine Fuzzy-Logik-Einheit angeordnet, die zusätzliche Messgrößen der Wäschelauge, z. B. die Oberflächenspannung oder den pH-Wert berücksichtigt.A fuzzy logic unit is preferably arranged in the program control unit 15, which additional measurement variables of the laundry detergent, for. B. the surface tension or the pH value is taken into account.
Durch die Erfindung wird ein wasserführendes Haushaltgerät wie eine Waschmaschine mit einer Mischbatterie 10 ausgestattet, die Teil einer Regeleinrichtung ist. Diese umfasst neben der Mischbatterie 10 den Regler 16, den Temperatursensor 12, den Wandler 13 und den Subtrahierer 14.
The invention provides a water-carrying household appliance, such as a washing machine, with a mixer tap 10, which is part of a control device. In addition to the mixer tap 10, this includes the controller 16, the temperature sensor 12, the converter 13 and the subtractor 14.
