Description

Die Erfindung betrifft eine Waschmaschine, insbesondere eine Haushaltswaschmaschine, mit einer Programmwahleinrichtung zur Anwahl von Waschprogrammen, welche verschiedenen Wäschearten zugeordnet sind, mit einem Laugenbehälter, in welchem eine Trommel drehbar gelagert ist, mit einer Waschmitteleinspülkammer mit mindestens einem Fach zur Aufnahme von Waschmittel, mit einer Einrichtung zur Ermittlung des Gewichts der in der Trommel befindlichen Wäsche, und mit einer Mikroprozessor-Steuerung zur Berechnung einer vom Gewicht der Wäsche abhängigen Waschmittel-Sollmenge für das jeweilige Waschprogramm.The invention relates to a washing machine, in particular a household washing machine a program selection device for selecting washing programs, which different Types of laundry are assigned, with a tub, in which a drum is rotatable is stored, with a detergent dispenser with at least one compartment for receiving of detergent, with a device for determining the weight of those in the drum Laundry, and with a microprocessor control to calculate a weight of the laundry-dependent set amount of detergent for the respective washing program.

Im Allgemeinen erfolgt bei Waschmaschinen die Zugabe von Waschmittel nach den Angaben des Herstellers auf dem jeweiligen Waschmittelpaket, unter Umständen mit Hilfe eines Meßbechers. Die Dosierung ist aber letztendlich dem Ermessen des Benutzers überlassen und deshalb ungenau. Statistischen Untersuchungen zufolge, kommt es in der Regel zu Überdosierungen.In general, detergents are added to washing machines according to the instructions of the manufacturer on the respective detergent package, possibly with the help of a measuring cup. The dosage is ultimately left to the discretion of the user and therefore inaccurate. According to statistical studies, overdoses usually occur.

Aus der DE 195 11 789 A1 ist eine Stelleinrichtung bekannt, mit welcher das Aufnahmevolumen einer Dosierkammer für Wasch- oder Geschirrspülmittel verändert werden kann. Diese Stelleinrichtung besteht aus einer elastischen Membran und einer damit verbundenen Schubstange. Die Stange wird in den Bedienbereich des Haushaltsgerätes geführt, so dass der Benutzer durch Einschieben oder Hinausziehen nach eigenem Gutdünken das Aufnahmevolumen der Dosierkammer und damit die jeweilige Wasch-/Spülmittelmenge beeinflussen kann. Auch diese Einrichtung führt letztendlich zu einer Dosierung, die vom Benutzer nach eigenem Ermessen festgelegt wurde und deshalb fehlerhaft sein kann.From DE 195 11 789 A1 an adjusting device is known with which the receiving volume a dosing chamber for detergents or dishwashing detergents can be changed. This Actuator consists of an elastic membrane and a connecting rod connected to it. The rod is guided into the operating area of the household appliance so that the Users by inserting or pulling out the volume as they see fit the dosing chamber and thus the respective amount of detergent / detergent can. In the end, this device also leads to a dosing by the user was determined at its own discretion and may therefore be incorrect.

Weiterhin ist insbesondere bei Spülmaschinen, aber auch bei Waschmaschinen eine automatische Dosierung konstanter Waschmittelmengen bekannt.Furthermore, an automatic one is particularly useful in dishwashers, but also in washing machines Dosage of constant amounts of detergent known.

Aus der GB 2 087 438 B ist es bei einer Trommelwaschmaschine bekannt, das Gewicht der Wäsche nach dem Einfüllen in die Trommel automatisch zu ermitteln und eine von diesem Gewicht abhängige Waschmittelmenge vorzuschlagen. Hierbei ergibt sich der Nachteil, daß der Benutzer diese Teilmenge anhand der Meßbecher-Skalierung abschätzen muß, wodurch es wieder zu Ungenauigkeiten bei der Waschmittelzugabe kommen kann.From GB 2 087 438 B it is known for a drum washing machine that the weight of the Automatically determine laundry after it is put into the drum and one of these Suggest weight dependent amount of detergent. This has the disadvantage that the User must estimate this subset based on the measuring cup scaling, which makes it again inaccuracies when adding detergent may occur.

Außerdem wird in der GB 2 087 438 B als Alternative vorgeschlagen, eine vom Gewicht der Wäsche abhängige automatische Dosierung des Waschmittels vorzunehmen. Eine automatische Dosierung ist jedoch zufriedenstellend nur mit Flüssigwaschmitteln möglich, welche vom Benutzer aber nur relativ selten verwendet werden. Außerdem sind zur automatischen Dosierung teure Zusatzeinrichtungen notwendig.GB 2 087 438 B also proposes as an alternative, one of the weight of the To carry out laundry-dependent automatic dosing of the detergent. An automatic Dosage is satisfactory only possible with liquid detergents, which from But users are used relatively rarely. Also for automatic dosing expensive additional equipment necessary.

Der Erfindung stellt sich somit das Problem, bei einer Waschmaschine der eingangs genannten Art die Dosierung von Waschmittel für den jeweiligen Waschgang zu erleichtern.The invention thus presents the problem in a washing machine of the type mentioned Type to facilitate the dosage of detergent for the respective wash cycle.

Erfindungsgemäß wird dieses Problem durch Waschmaschinen mit den in den unabhängigen Patentansprüchen 1 bis 3 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen. According to the invention this problem is solved by washing machines with the in the independent Claims 1 to 3 specified features solved. Advantageous configurations and Further developments of the invention result from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen in einer exakten Steuerung des Dosiervorgangs, wodurch Überdosierungen weitestgehend vermieden werden.The advantages achievable with the invention consist in exact control of the dosing process, whereby overdoses are largely avoided.

In einer vorteilhaften Ausführungsform der Erfindung ist eine Einrichtung zur Eingabe der Art und/oder spezifischen Dichte des verwendeten Waschmittels vorhanden. Hierdurch werden die unterschiedlichen Dichten von Kompakt- und Normalwaschmitteln berücksichtigt.In an advantageous embodiment of the invention, a device for entering the type and / or specific density of the detergent used. This will make the different densities of compact and normal detergents are taken into account.

Es hat sich als besonders vorteilhaft erwiesen, einen Strichcode-Leser zur Identifizierung eines verwendeten Waschmittels vorzusehen und aus einem Speicher in Abhängigkeit des identifizierten Waschmittels einen Wert für dessen spezifische Dichte abzurufen. Auf diese Weise wird die Eingabe vereinfacht und Fehler vermieden.It has proven particularly advantageous to use a barcode reader to identify a provide detergent used and from a memory depending on the identified Detergent to get a value for its specific density. That way simplifies entry and avoids errors.

Es ist weiterhin vorteilhaft, wenn die Mikroprozessor-Steuerung den für ein jeweiliges Programm ermittelten oder eingegebenen Wert in einem nichtflüchtigen Speicher ablegt und bei Anwahl des gleichen Programms mit der Programmwahleinrichtung erneut abruft. Hierdurch muß die Eingabe der Art und/oder spezifischen Dichte nur bei Verwendung eines neuen Waschmittels eingegeben werden.It is also advantageous if the microprocessor control for a particular program stores the determined or entered value in a non-volatile memory and at Selection of the same program with the program selector again. hereby you only have to enter the type and / or specific density when using a new one Detergent can be entered.

Figur 2) vorgesehen, die über Signalleitungen (14) mit verschiedenen Meßgebem und den Bedienelementen verbunden ist. Sie gibt zeit- und zustandsabhängige Befehle über Steuerleitungen (15) an verschiedene Aktoren (Motoren, Ventile, Anzeigeelemente ...) weiter.A microprocessor control (MC) is used to control the different washing programs (see Figure 2) provided, the signal lines (14) with various transducers and Controls is connected. It issues time and status-dependent commands via control lines (15) to various actuators (motors, valves, display elements ...).

Unter den Meßgebem der erfindungsgemäß ausgebildeten Waschmaschine (1) befindet sich ein erster Gewichtssensor (16), mit dem die Beladungsmenge der Trommel (3) ermittelt werden kann. Als Sensor kann in bekannter Weise ein Lagesensor verwendet werden, mit welchem die gewichtsabhängige Laugenbehälterabsenkung erfaßt wird. Andere Gewichtssensoren (beispielsweise Dehnungsmeßstreifen) oder andere Verfahren zur Feststellung von Art und/oder Gewicht der Beladung können ebenfalls verwendet werden.Is located under the Meßgebem the washing machine (1) designed according to the invention a first weight sensor (16) with which the loading quantity of the drum (3) is determined can. As a sensor, a position sensor can be used in a known manner, with which the weight-dependent lowering of the tub is detected. Other weight sensors (e.g. strain gauges) or other methods to determine Art and / or load weight can also be used.

Ein weiterer Gewichtssensor (17) ist an der Waschmittelschublade (12) angeordnet und ermittelt das Gewicht der vom Benutzer eingefüllten Waschmittel-Istmenge. Dieses Gewichtssignal wird ebenfalls an die Mikroprozessor-Steuerung (MC) weitergegeben. Anstelle dieses Gewichtssensors (17) kann ein Füllstandssensor verwendet werden.Another weight sensor (17) is arranged on the detergent drawer (12) determines the weight of the actual amount of detergent filled by the user. This weight signal is also passed on to the microprocessor control (MC). Instead of this Weight sensor (17), a level sensor can be used.

Figur 2 zeigt die Bedienelemente der Waschmaschine (1) in vergrößerter Form. Mit dem Drehwahlschalter (18) wird das durchzuführende Programm für den Waschvorgang je nach Wäscheart und Temperatur ausgewählt. Weitere Zusatzfunktionen sind durch Drucktastenschalter (19) anwählbar. Dabei kann mit einer Taste "Stark verschmutzt" (nicht dargestellt) der Verschmutzungsgrad der Wäsche eingegeben werden. Die Mikroprozessor-Steuerung (MC) steht über eine Steuerleitung (15) mit einer Signaleinrichtung in Form einer Anzeigelampe (20) in Verbindung.Figure 2 shows the controls of the washing machine (1) in an enlarged form. With the Rotary selector switch (18) the program to be carried out for the washing process depending on Laundry type and temperature selected. Other additional functions are by push button switches (19) can be selected. You can use a "heavily soiled" button (not shown) Degree of soiling of the laundry can be entered. The microprocessor control (MC) stands via a control line (15) with a signal device in the form of an indicator lamp (20) in connection.

Ein weiteres Eingabeelement dient zur Übermittlung der spezifischen Dichte des verwendeten Waschmittels. Die Eingabe kann entweder manuell durch ein Tastenfeld (nicht dargestellt) erfolgen oder über einen Strichcode-Leser (21), über den die Mikroprozessor-Steuerung (MC) Angaben über die Art des Waschmittels von der Verpackung einliest und hiervon abhängig den Wert für die Dichte aus einem ersten Speicher (SP 1) abruft. Darüber hinaus ist in der Steuerung ein zweiter nichtflüchtiger Speicher (Sp 2) integriert, in dem für jede mit dem Drehwahlschalter (18) einstellbare Wäscheart ein Wert für eine spezifische Waschmitteldichte zugeordnet werden kann.Another input element is used to transmit the specific density of the used Detergent. Entry can either be done manually using a keypad (not shown) take place or via a barcode reader (21) via which the microprocessor control (MC) Reads information about the type of detergent from the packaging and depending on it Retrieves value for the density from a first memory (SP 1). In addition, in the Control integrated a second non-volatile memory (Sp 2), in which for each with the Rotary selector switch (18) adjustable laundry type a value for a specific detergent density can be assigned.

Die Funktionsweise der gezeigten Anordnung ist wie folgt:The arrangement works as follows:

Zunächst schaltet der Benutzer das Gerät durch Drücken der Taste "Ein/Aus" (22) ein. Danach füllt er die zu waschende Wäsche (4) in die Trommel (3). Anschließend wird mit dem Drehwahlschalter (18) das durchzuführende Programm für den Waschvorgang je nach Wäscheart und Temperatur ausgewählt. Zusatzfunktionen können über Drucktastenschalter (19) eingestellt werden.First, the user switches the device on by pressing the "On / Off" button (22). After that he fills the laundry (4) to be washed into the drum (3). Then use the rotary selector switch (18) the program to be carried out for the washing process depending on the type of laundry and Temperature selected. Additional functions can be set using the push button switch (19) become.

Vor dem erstmaligen Programmstart in einer Wäscheart muß der Benutzer einen Wert für die spezifische Dichte des für diese Wäsche (4) verwendeten Waschmittels eingeben. Dieser Wert wird in einem nichtflüchtigen Speicher (SP 2) abgelegt und der entsprechenden Wäscheart zugeordnet. Auf diese Weise wird dem Umstand Rechnung getragen, daß für unterschiedliche Textilien verschiedene Waschmittel verwendet werden. Der Wert für die spezifische Dichte wird über das Programmende hinaus im nichtflüchtigen Speicher (SP 2) registriert, so daß Neueingaben nur bei Änderung des Waschmittels notwendig sind.Before the first program start in a type of laundry, the user must have a value for the Enter the specific density of the detergent used for this laundry (4). This value is stored in a non-volatile memory (SP 2) and the corresponding type of laundry assigned. In this way, the fact is taken into account that for different Textiles different detergents can be used. The specific gravity value will beyond the end of the program in the non-volatile memory (SP 2) registered, so that new entries are only necessary when changing the detergent.

Die Mikroprozessor-Steuerung (MC) startet nun das Waschprogramm mit einer Sequenz zur Eingabe des Waschmittels. In Abhängigkeit vom Wäschegewicht und der spezifischen Waschmitteldichte errechnet sie eine Waschmittel-Sollmenge (in Gramm). Wurde die Taste "Stark verschmutzt" betätigt, wird die Sollmenge bei Programmen, bei denen Vollwaschmittel verwendet wird (Kochwäsche/Buntwäsche; Mini) um 50% und bei Programmen, bei denen Feinwaschmittel verwendet wird (Feinwäsche ...) um 20% erhöht. Die Sollmenge wird nun laufend mit dem Gewicht der in das Fach (11) eingefüllten Waschmittel-Istmenge verglichen. Erreicht die Waschmittel-lstmenge den berechneten Sollmengen-Wert, wird die Anzeigelampe (20) angesteuert und leuchtet auf. Eine Überfüllung kann durch ein Blinksignal angezeigt werden. Um das Einfüllen von Waschmittel für weitere Programmteile (Vorwäsche) oder Weichspüler zu ermöglichen, ist eine Quittier-Taste (23) neben der Anzeigelampe (20) angeordnet. Die Sequenz zur Eingabe des Waschmittels muß dann dem gewählten Programm entsprechend mehrmals abgearbeitet werden. Nach dem Schließen der Waschmittelschublade (12) kann das Waschprogramm durch Drücken der Taste "Start" (24) ausgeführt werden.The microprocessor control (MC) now starts the washing program with a sequence Enter the detergent. Depending on the laundry weight and specific detergent density it calculates a target amount of detergent (in grams). Has the "Strong dirty "is pressed, the target amount for programs in which heavy detergents is used (cottons / colored clothes; mini) by 50% and in programs where Fine detergent is used (delicates ...) increased by 20%. The target quantity is now continuously compared with the weight of the actual amount of detergent filled in the compartment (11). If the actual detergent quantity reaches the calculated target quantity value, the indicator lamp will light up (20) activated and lights up. Overflowing can be indicated by a flashing signal become. To fill in detergent for other program parts (prewash) or To enable fabric softener, an acknowledgment button (23) is arranged next to the indicator lamp (20). The sequence for entering the detergent must then follow the selected program be processed several times accordingly. After closing the detergent drawer (12) the washing program can be carried out by pressing the "Start" button (24).

Figur 3 zeigt eine weitere Ausführungsform der Erfindung. Dort ist in der Waschmittelschublade (12) im Fach (11) für die Hauptwäsche eine Schiebeplatte (25) integriert, mit der das Aufnahmevolumen dieses Fachs (11) mit Hilfe eines Stellmotors (26) über ein Ritzel (27) und eine Zahnstange (28) verändert werden kann.
