Description

Die Erfindung betrifft eine Waschmaschine mit einer Programmsteuerung, mit einem an Federn schwingend aufgehängten oder abgestützten Laugenbehälter, in dem eine Trommel zur Aufnahme von Wäsche drehbar gelagert und über einen Motor im Wasch- und Schleudergang antreibbar ist, und mit einer Einrichtung zur Erzeugung eines vom Wäschegewicht abhängigen Signals.The invention relates to a washing machine with a program control, with a spring swinging suspended or supported tub, in which a drum for recording of laundry rotatably and via a motor in the wash and spin cycle is drivable, and with a device for generating a laundry weight dependent Signal.

Bei den eingangs genannten Waschmaschinen ist es bekannt, das Gewicht der in die Trommel eingelegten Wäsche durch Auswertung der relativen Höhenänderung zwischen dem Laugenbehälter und dem Gehäuse zu bestimmen. Hierzu wird beispielsweise in der DE 22 04 325 C2 die Verwendung eines induktiven Bewegungsaufnehmers im Bereich eines Stoßdämpfers vorgeschlagen. Daneben ist es bekannt, anstelle der Höhenänderung die Änderung der vom Laugenbehälter auf das Gehäuse übertragenen Gewichtskraft auszuwerten. Hierzu ist beispielsweise aus der DE-OS 20 34 847 die Verwendung von mechanisch-elektrischen Wandlern bekannt.In the washing machines mentioned above, it is known the weight of the drum inserted laundry by evaluating the relative change in height between the tub and determine the housing. For this purpose, for example, in DE 22 04 325 C2 the use of an inductive motion sensor in the area of a shock absorber proposed. In addition, it is known that instead of the change in height, the change of the Evaluate the tub on the weight transferred to the housing. This is for example from DE-OS 20 34 847 the use of mechanical-electrical transducers known.

Bei diesen Waschmaschinen ist es weiterhin bekannt, neben der Gewichtsmessung, die durch eine Auswertung des statischen Signalanteils des Weg- oder Kraftsensors erfolgt, den dynamischen Signalanteil des Sensorsignals im Schleudergang auszuwerten. In der DE 89 05 566 U1 wird dieser Signalanteil zur Erkennung von Unwuchten der drehenden Trommel herangezogen. Unwuchten werden beispielsweise durch ungünstige Wäscheverteilung in der Trommel während des Schleuderns hervorgerufen.In these washing machines, it is also known, in addition to the weight measurement by an evaluation of the static signal component of the displacement or force sensor takes place, the dynamic one Evaluate the signal portion of the sensor signal in the spin cycle. In DE 89 05 566 U1 this signal component is used to detect imbalances in the rotating drum. Imbalances are caused, for example, by unfavorable laundry distribution in the drum caused during the spin cycle.

Weiterhin ist aus der DE 41 04 151 A1 bekannt, eine durch Überdosierung von Waschmittel hervorgerufene vermehrte Schaumbildung durch eine Leitwertmeßeinrichtung, eine Druckmeßeinrichtung oder eine Lichtschrankenanordnung zu sensieren. Diese Sensoren sind teuer und störungsanfällig (Leitwertmessung, Lichtschranke) oder wegen ihrer Ungenauigkeit unzuverlässig (Druckmessung).Furthermore, it is known from DE 41 04 151 A1, one by overdosing detergent caused increased foam formation by a conductance measuring device, a pressure measuring device or to sense a light barrier arrangement. These sensors are expensive and susceptible to malfunction (conductance measurement, light barrier) or unreliable due to its inaccuracy (Pressure measurement).

Der Erfindung stellt sich somit das Problem, bei einer Waschmaschine der eingangs genannten Art mit einfachen Mitteln eine genaue Schaumsensierung zu ermöglichen.The invention thus presents the problem in a washing machine of the type mentioned Art to enable precise foam detection with simple means.

Erfindungsgemäß wird dieses Problem durch eine Waschmaschine mit den im Patentanspruch 1 angegebenen Merkmalen gelöst.According to the invention this problem is solved by a washing machine with in the claim 1 specified features solved.

Bei der erfindungsgemäßen Ausbildung der Waschmaschine wird das Phänomen ausgenutzt, daß der in der Trommel vorhandenen Schaum den Wäschefall dämpft, der durch die Trommeldrehung und durch das Reversieren hervorgerufen wird. Der Wäschefall wiederum verursacht Schwankungen des Gewichtssignals. Auf diese Weise kann vorteilhafterweise der bereits vorhandene Gewichtssensor auch zur Schaumsensierung genutzt werden.In the construction of the washing machine according to the invention, the phenomenon is exploited that the foam in the drum dampens the laundry, caused by the rotation of the drum and is caused by reversing. The laundry case in turn causes Fluctuations in the weight signal. In this way, the already can existing weight sensor can also be used for foam detection.

In einer vorteilhaften Weiterbildung der Erfindung wird die Auswerteschaltung dazu genutzt, den Zeitwert einer Programmlaufzeit-Anzeigevorrichtung in Abhängigkeit von der ermittelten Schaumbildung bzw. deren Menge zu korrigieren. Hierdurch wird die Notwendigkeit zur Verlangsamung oder Änderung der Schleuderdrehzahl-Profile früh erkannt und bei der Anzeige der Programmlaufzeit berücksichtigt.In an advantageous development of the invention, the evaluation circuit is used to the time value of a program runtime display device depending on the determined Correct foam formation or its amount. This eliminates the need to slow down or change in the spin speed profiles detected early and when displaying the Program duration considered.

Die in Figur 1 dargestellte Waschmaschine besitzt in bekannter Weise einen Laugenbehälter (1), in dem eine Trommel (2) zur Aufnahme von Wäsche drehbar gelagert ist. Der Antrieb der Trommel erfolgt über einen Motor (3). Der Laugenbehälter (1) ist an Federn (4) schwingbeweglich im Gehäuse (5) aufgehängt und wird zur Dämpfung dieser Schwingungen im unteren Bereich durch Stoßdämpfer (6) gegenüber dem Gehäuseboden (7) abgestützt.The washing machine shown in Figure 1 has a tub in a known manner (1), in which a drum (2) for receiving laundry is rotatably mounted. The The drum is driven by a motor (3). The tub (1) is on springs (4) swingably suspended in the housing (5) and is used to dampen these vibrations in the lower area supported by shock absorbers (6) against the housing base (7).

Zur Steuerung der verschiedenen Waschprogramme ist eine Mikroprozessor-Steuerung (8) vorgesehen, die über Signalleitungen (9) mit verschiedenen Meßgebern und den Bedienelementen (nicht dargestellt) verbunden ist. Sie gibt zeit- und zustandsabhängige Befehle über Steuerleitungen (10) an verschiedene Aktoren weiter. Dabei wird insbesondere der Motor (3) mit verschiedenen Drehzahlen zum Antrieb der Trommel (2) im Waschgang und im Schleudergang von der in der Mikroprozessor-Steuerung integrierten Motorregelung (R) angesteuert.A microprocessor control (8) is used to control the different washing programs. provided that via signal lines (9) with various sensors and the controls (not shown) is connected. It transfers time and status-dependent commands Control lines (10) to various actuators. In particular, the motor (3) with different speeds to drive the drum (2) in the wash cycle and in the spin cycle controlled by the motor control (R) integrated in the microprocessor control.

Unter den Meßgebern der erfindungsgemäß ausgebildeten Waschmaschine befindet sich ein Gewichtssensor, mit dem die Beladungsmenge der Trommel ermittelt werden kann. Als Sensor wird in bekannter Weise ein parallel zum Stoßdämpfer angeordneter Lagesensor (11) verwendet, mit welchem die gewichtsabhängige Laugenbehälterabsenkung erfaßt wird. Andere Gewichtssensoren, beispielsweise Dehnungsmeßstreifen, können ebenfalls verwendet werden. Der statische Anteil des Lagesensor (11)-Signals wird von der Mikroprozessor-Steuerung (8) zur Bestimmung des Wäschegewichts ausgewertet und beispielsweise in einer in den Zeichnungen nicht dargestellten Gewichtsanzeige angezeigt. Der dynamische Signalanteil wird in bekannter Weise von einer in der Mikroprozessor-Steuerung integrierten Auswerteschaltung (A) ausgefiltert und zur Sensierung des Schaumaufkommens im Laugenbehälter (1) herangezogen. Anstelle des Gewichtssensors kann auch ein aus der DE 195 22 393 A1 bekannter Beschleunigungssensor verwendet werden.Among the sensors of the washing machine designed according to the invention is a Weight sensor with which the load quantity of the drum can be determined. As a sensor a position sensor (11) arranged parallel to the shock absorber is used in a known manner, with which the weight-dependent lowering of the tub is recorded. Other Weight sensors, such as strain gauges, can also be used. The static part of the position sensor (11) signal is controlled by the microprocessor control (8) evaluated to determine the laundry weight and, for example, in one of the Weight not shown in the drawings. The dynamic signal component is in a known manner from an evaluation circuit integrated in the microprocessor control (A) filtered out and to sense the amount of foam in the tub (1) used. Instead of the weight sensor, one from DE 195 22 393 A1 known acceleration sensor can be used.

Figur 2 zeigt als Weg-Zeit-Diagramm das Sensorsignal während des Waschgangs mit Schaum (Signal I) und ohne Schaum (Signal II). Dabei wurde zur übersichtlicheren Darstellung das Signal I mit einem Offset belegt. Der Vergleich der Signale zeigt, daß die durch den Wäschefall und das Reversieren der Trommel (2) bedingten Signalschwankungen vom Schaum nahezu vollständig gedämpft werden. Somit kann die Auswerteschaltung (A) durch Ermittlung der Standardabweichung des dynamischen Signalanteils ein vermehrtes Schaumaufkommen im Waschgang sensieren. Ist dies der Fall, werden anschließend im Schleudergang das Drehzahlprofil im Schleuderhochlauf hinsichtlich Höhe und Beschleunigung an die ermittelte Schaummenge angepaßt. Daneben kann das Waschprogramm hinsichtlich seiner Länge und die Spülgänge hinsichtlich ihrer Dauer, Anzahl und/oder der verwendeten Spülwassermenge an das vermehrte Schaumaufkommen angepaßt werden. Außerdem können hierdurch bedingte Laufzeit-Verlängerungen bei der Anzeige der Programmlaufzeit (nicht dargestellt) berücksichtigt werden.Figure 2 shows a path-time diagram of the sensor signal during the wash with foam (Signal I) and without foam (Signal II). This was for a clearer presentation Signal I assigned an offset. The comparison of the signals shows that the laundry and the reversing of the drum (2) caused signal fluctuations from the foam almost be completely dampened. The evaluation circuit (A) can thus be determined by determining the Standard deviation of the dynamic signal component an increased amount of foam in the Sensing the wash cycle. If this is the case, the speed profile is then determined in the spin cycle in spin-up with regard to height and acceleration to the determined amount of foam customized. In addition, the length and length of the wash program Rinse cycles in terms of their duration, number and / or the amount of rinse water used the increased foam volume can be adjusted. In addition, this can cause Runtime extensions are taken into account when displaying the program runtime (not shown) become.
