Description

Dosiervorrichtung Dosing device
Die vorliegende Erfindung betrifft eine Dosiervorrichtung zum Zudosieren von vorzugsweise Flüssigwaschmittel aus einem Vorratsbehalter in einen Mischraum, insbesondere Laugenbehälter einer Waschmaschine.The present invention relates to a metering device for metering preferably liquid detergent from a storage container into a mixing room, in particular a washing machine tub.
Bei herkömmlichen Waschmaschinen wird ein Waschmittel z.B. in flüssiger Form aus einem Vorratsbehalter, z.B. einem Einspülkasten für Waschmittel, in die Waschflotte zudo- siert. Das Dosieren des Waschmittels wird vorab durch Ein¬ füllen einer bestimmten Menge von flüssigem Waschmittel in den Einspülkasten vorgenommen und kann nicht während des Waschens an die tatsächlich notwendige Waschmittelmenge angepaßt werden. Wird eine zu große Waschmittelmenge ver¬ wendet, so gelangt ein Teil des Waschmittel-Überschusses in z.B. Textilien, womit Hautreizungen und eine Ver¬ schlechterung der Textilien verbunden sein können, und der andere Teil in das Abwasser und belastet die Umwelt. Wenn die Waschmittelmenge zu gering gewählt wurde, so werden die Textilien nur unzureichend gereinigt.In conventional washing machines, a detergent e.g. in liquid form from a storage container, e.g. a detergent dispenser into the wash liquor. The detergent is dosed beforehand by pouring a certain amount of liquid detergent into the dispenser drawer and cannot be adapted to the amount of detergent actually required during washing. If too much detergent is used, some of the excess detergent ends up in e.g. Textiles, with which skin irritation and deterioration of the textiles can be connected, and the other part into the waste water and pollutes the environment. If the amount of detergent selected is too small, the textiles will be cleaned insufficiently.
Der vorliegenden Erfindung liegt somit die Aufgabe zugrun¬ de, eine Dosierrichtung zur Verfügung zu stellen, mit der eine automatische, von der Menge und dem Verschmutzungs¬ grad des Waschguts abhängige Waschmitteldosierung ermög¬ licht wird. Erfindungsgemäß wird diese Aufgabe dadurch gelöst, daß die Dosiervorrichtung in einem flüssigkeitsdichten, in eine Waschflotte einbringbaren Gehäuse die Komponenten umfaßt:The present invention is therefore based on the object of making available a metering direction by means of which automatic detergent metering, which is dependent on the amount and degree of soiling of the laundry, is made possible. According to the invention, this object is achieved in that the metering device comprises the components in a liquid-tight housing which can be introduced into a washing liquor:
- den Vorratsbehalter;- the storage container;
- eine dem Vorratsbehalter zugeordnete Dosiereinrichtung;- A metering device assigned to the storage container;
- eine Sensoreinrichtung zur Bestimmung der Waschmittel- konzentration in der Waschflotte;- A sensor device for determining the detergent concentration in the wash liquor;
- eine der Sensoreinrichtung nachgeschaltete Regeleinrich¬ tung für die Waschmittelkonzentration; unda control device for the detergent concentration downstream of the sensor device; and
- eine Energieversorgungseinrichtung.- An energy supply facility.
Dabei kann vorgesehen sein, daß die Dosiereinrichtung ein Ventil umfaßt.It can be provided that the metering device comprises a valve.
Ferner kann auch vorgesehen sein, daß die Dosiereinrich¬ tung eine Pumpe umfaßt.It can also be provided that the metering device comprises a pump.
In einer besonderen Ausführungsform der Erfindung kann vorgesehen sein, daß die Sensoreinrichtung einen Sensor zur Messung des pH-Wertes der Waschflotte umfaßt.In a special embodiment of the invention it can be provided that the sensor device comprises a sensor for measuring the pH value of the wash liquor.
Vorteilhafterweise umfaßt die Sensoreinrichtung zusätzlich einen Sensor zur Messung der Leitfähigkeit der Waschflot¬ te.The sensor device advantageously additionally comprises a sensor for measuring the conductivity of the washing liquor.
In einer besonders bevorzugten Ausführungsform umfaßt die Sensoreinrichtung zusätzlich einen Sensor zur Messung der Temperatur der Waschflotte.In a particularly preferred embodiment, the sensor device additionally comprises a sensor for measuring the temperature of the wash liquor.
Außerdem kann vorgesehen sein, daß die Sensoreinrichtung einen Sensor zur Messung der Konzentration einer in dem in die Waschflotte eingebrachten Waschmittel vorhandenen Sub¬ stanz umfaßt. Vorzugsweise umfaßt die Regeleinrichtung einen elektrisch betriebenen Meßwert-Verstärker sowie einen Komperator für einen Ist-Soll-Vergleich.It can also be provided that the sensor device comprises a sensor for measuring the concentration of a substance present in the detergent introduced into the washing liquor. The control device preferably comprises an electrically operated measurement value amplifier and a comparator for an actual-target comparison.
Günstigerweise umfaßt die Energieversorgungseinrichtung mindestens eine Batterie.The energy supply device advantageously comprises at least one battery.
Weiterhin kann vorgesehen sein, daß die Energieversor¬ gungseinrichtung mindestens ein Thermoelement zur Energie¬ versorgung umfaßt.Furthermore, it can be provided that the energy supply device comprises at least one thermocouple for energy supply.
Darüber hinaus kann vorgesehen sein, daß die Energiever¬ sorgungseinrichtung einen mechanischen Schwunganker-Gene¬ rator umfaßt.In addition, it can be provided that the energy supply device comprises a mechanical swing armature generator.
Außerdem kann vorgesehen sein, daß die Dosiervorrichtung eine Einrichtung zur Bestimmung der Wasserhärte umfaßt.It can also be provided that the metering device comprises a device for determining the water hardness.
Schließlich kann vorgesehen sein, daß das Gehäuse Kugelge¬ stalt aufweist.Finally, it can be provided that the housing has a spherical shape.
Der Erfindung liegt die überraschende Erkenntnis zugrunde, daß durch die erfindungsgemäße Anordnung und Verbindung einer Sensoreinrichtung mit einer Regeleinrichtung und einer Dosiereinrichtung eine kompakte Dosiervorrichtung erzielt wird, mit der direkt in einem Mischraum oder im Bereich desselben eine Bestimmung der Waschmittelkonzen¬ tration und in Abhängigkeit von diesem Wert ein Zudosieren des Waschmittels vorgenommen werden kann. Da die Dosier¬ vorrichtung in der Waschflotte sowohl mechanisch bewegt als auch in der Regel erwärmt wird, kann darüber hinaus durch Verwendung eines Thermoelements oder dergleichen bzw. eines mechanischen Schwunganker-Generators eine eige¬ ne, d.h. ohne Verwendung von Batterien, Energieversorgung erzielt werden. Eine Sensoreinrichtung mit Sensoren zur kombinierten Mes¬ sung von pH-Wert, Leitfähigkeit und Temperatur der Wasch¬ flotte bietet besonders gute Regelungsmöglichkeiten, da sowohl der pH-Wert als auch die Leitfähigkeit relativ stark vom Tensidgehalt abhängen und somit unter Berück¬ sichtigung der Temperatur zur Bestimmung der Waschmittel- konzentration besonders geeignet sind.The invention is based on the surprising finding that, by the arrangement and connection of a sensor device with a control device and a metering device according to the invention, a compact metering device is achieved with which the detergent concentration can be determined directly in a mixing room or in the area thereof and as a function thereof Value can be added to the detergent. Since the metering device in the wash liquor is both moved mechanically and is generally heated, it is also possible, by using a thermocouple or the like or a mechanical flywheel armature generator, to achieve a power supply of its own, ie without using batteries. A sensor device with sensors for combined measurement of the pH value, conductivity and temperature of the washing liquor offers particularly good control options, since both the pH value and the conductivity depend relatively strongly on the surfactant content and therefore taking the temperature into account Determination of the detergent concentration are particularly suitable.
Bei Verwendung einer Einrichtung zur Bestimmung der Was¬ serhärte kann darüber hinaus auch ein grundsätzlicher Mehr- oder Minderbedarf an Waschmittel aufgrund einer ho¬ hen bzw. geringen Wasserhärte berücksichtigt werden.When using a device for determining the water hardness, it is also possible to take into account a basic need for more or less detergent due to a high or low water hardness.
Wird ein spezielles Waschmittel verwendet, welches eine PilotSubstanz (Indikator) enthält, so kann die Waschmit¬ telkonzentration über deren Konzentration in der Wasch¬ flotte laufend gemessen werden.If a special detergent is used which contains a pilot substance (indicator), the detergent concentration can be measured continuously via its concentration in the washing liquor.
Weitere Merkmale und Vorteile der Erfindung ergeben sich aus der nachstehenden Beschreibung, in der ein Ausfüh¬ rungsbeispiel anhand der schematischen Zeichnung im ein¬ zelnen erläutert ist.Further features and advantages of the invention result from the following description, in which an exemplary embodiment is explained in detail with reference to the schematic drawing.
Die Figur zeigt eine Ausführungsform der erfindungsgemäßen Dosiervorrichtung. Die Dosiervorrichtung 10 weist ein ku¬ gelförmiges Gehäuse 12 aus Kunststoff auf. Das Gehäuse 12 weist einen Schraubverschluß 26 zum Einfüllen von Wasch¬ mittel in einen Vorratsbehalter 14 und eine Ventileinrich¬ tung 16 als Dosiereinrichtung für das Waschmittel auf. Weiterhin weist das Gehäuse 12 eine Ausnehmung für eine pH-Wert-Meßelektrode 18 und ein verschraubbares Fach für eine Batterie 24 zur Energieversorgung auf. Die pH-Wert- Meßelektrode 18 dient dazu, die Waschmittelkonzentration indirekt über den pH-Wert der Waschflotte zu bestimmen. Alle Elemente (26, 18, 24) sind derart angeordnet, daß sie nicht über die Umfangskontur des Gehäuses 12 hinausragen. Neben der Energieversorgungseinrichtung 24 befindet sich eine Regeleinrichtung 22, die einen elektrisch betriebenen Meßwert-Verstärker sowie Komperator zum Ist-Soll-Vergleich umfaßt und das Ventil 16 steuert, um sicherzustellen, daß das Waschmittel lediglich in dosierter Form in Abhängig¬ keit von der von der pH-Meßelektrode 18 gemessenen pH-Wert der Waschflotte in die Waschflotte entlassen wird, so daß also insgesamt der pH-Wert der Waschflotte auf einem vor¬ gebbaren Soll-Wert gehalten werden kann. Sinkt der von der pH-Meßelektrode 18 gemessene pH-Wert (Ist-Wert) der Wasch¬ flotte in Richtung auf den sauren Bereich ab, wenn z.B. für einen bestimmten Schmutzanteil aufgrund der zu wa¬ schenden Wäschestücke zu wenig Waschmittel vorhanden ist, so wird über die Regeleinrichtung 22 das Ventil 16 geöff¬ net und gelangt weiteres Waschmittel in die Waschflotte.The figure shows an embodiment of the metering device according to the invention. The metering device 10 has a spherical housing 12 made of plastic. The housing 12 has a screw cap 26 for filling detergent into a storage container 14 and a valve device 16 as a metering device for the detergent. Furthermore, the housing 12 has a recess for a pH value measuring electrode 18 and a screwable compartment for a battery 24 for energy supply. The pH value measuring electrode 18 serves to determine the detergent concentration indirectly via the pH of the wash liquor. All elements (26, 18, 24) are arranged such that they do not protrude beyond the circumferential contour of the housing 12. In addition to the energy supply device 24 there is a control device 22 which comprises an electrically operated measuring value amplifier and comparator for the actual-target comparison and controls the valve 16 in order to ensure that the detergent is only in dosed form depending on the condition of the pH measuring electrode 18 measured pH of the wash liquor is released into the wash liquor, so that overall the pH of the wash liquor can be kept at a predetermined target value. If the pH value (actual value) of the washing liquor measured by the pH measuring electrode 18 drops in the direction of the acidic range, for example if too little detergent is available for a certain proportion of dirt due to the items to be washed, then The valve 16 is opened via the control device 22 and further detergent enters the wash liquor.
Die "Dosierkugel" 10 wird vor einem jeweiligen Waschgang bei Bedarf mit Waschmittel aufgefüllt und vorzugsweise in einen Laugenbehälter einer Waschmaschine eingebracht. Um bei einer Waschmitteldosierung die Wasserhärte zu berück¬ sichtigen, kann die Dosiervorrichtung 10 zusätzlich eine Einrichtung zur Bestimmung der Wasserhärte (nicht gezeigt) aufweisen.The "dosing ball" 10 is filled with detergent before a respective wash cycle, if necessary, and is preferably placed in a washing machine tub. In order to take the water hardness into account when dosing detergent, the dosing device 10 can additionally have a device for determining the water hardness (not shown).
