Description
Die Erfindung betrifft eine Waschmaschine mit einer motorisch angetriebenen Wasch- und Schleudertrommel nach dem Oberbegriff des Patentanspruches.The invention relates to a washing machine with a motor-driven washing and spinning drum according to the preamble of the claim.
Es ist bei Waschmaschinen allgemein bekannt, für deren Wasch- und Schleudertrommel eine Unwuchtüberwachungseinrichtung (Unwuchterkennungseinrichtung) vorzusehen, durch die bei Auftreten bzw. Erfassen einer Unwucht in Folge ungünstiger Waschgutverteilung in der Wasch- und Schleudertrommel deren Drehzahl reduziert oder der Antrieb vorübergehend stillgesetzt wird. Während dieser Phase findet eine neue Wäschegutverteilung in der Wasch- und Schleudertrommel statt. Danach ist automatisch ein erneutes Hochlaufen der Wasch- und Schleudertrommel bzw. ein Wiederanlaufen des Antriebes vorgesehen. Dieser Vorgang einer günstigen Waschgutverteilung in der Wasch- und Schleudertrommel kann während des Schleuderprozesses unter Umständen mehrmals wiederholt werden.It is generally known in washing machines to provide an unbalance monitoring device (unbalance detection device) for their washing and centrifuging drum, by means of which the rotation speed is reduced or the drive is temporarily stopped when an unbalance occurs or is detected as a result of unfavorable distribution of laundry in the washing and centrifuging drum. During this phase, a new laundry distribution takes place in the washing and spinning drum. After that, the washing and centrifuging drum is automatically restarted or the drive restarted. This process of favorable laundry distribution in the washing and spinning drum can be repeated several times during the spinning process.
Bei diesem Vorgang der Wäscheunwuchtbeseitigung bzw. -korrektur läuft jedoch das mechanische Programmschaltwerk stetig weiter, d. h. die für den Schleuderprozeß vorgesehenen Zeitschritte des Programmschaltwerkes werden von diesem laufend abgearbeitet. Die für die Wächeunwuchtbeseitigung bzw. -korrektur und die damit verbundenen Wächeunwuchtmeßzyklen aufgewendete Zeit geht dadurch der vorgegebenen Schleuderzeit ab. Die Folge davon ist, daß die effektive Schleuderzeit verkürzt wird und diese Zeit dann nicht mehr ausreichend ist, die Wäsche zufriedenstellend zu entwässern. Eine Waschmaschine, bei der das Programmschaltwerk stetig weiter läuft, ist aus der DE-A-2620464 bekannt.In this process of removing or correcting laundry imbalance, however, the mechanical program switching mechanism continues to run, ie the time steps of the program switching mechanism provided for the spinning process are continuously processed by the latter. The time expended for the removal or correction of the imbalance and the associated imbalance measuring cycles thus goes beyond the predetermined spin time. The result of this is that the effective spinning time is reduced and this time is then no longer sufficient, the laundry to drain satisfactorily. A washing machine in which the program switching mechanism continues to run is known from DE-A-2620464.
Der Erfindung liegt nun die Aufgabe zugrunde, den aufgezeigten Mangel zu beheben, und sicherzustellen, daß die Wäscheunwuchtbeseitigung bzw. -korrektur keinen negativen Einfluß auf das erwünschte Schleuderergebnis hat.The invention is based on the object to remedy the shortcoming and to ensure that the laundry imbalance removal or correction has no negative influence on the desired spin result.
Die gestellte Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Antrieb des mechanischen Programmschaltwerkes für die Dauer der Waschgutverteilung und/oder einer Waschgutverteilungsmessung und/oder einer Waschgutverteilungskorrektur angehalten wird.The object is achieved according to the invention in that the drive of the mechanical program switching mechanism is stopped for the duration of the laundry distribution and / or a laundry distribution measurement and / or a laundry distribution correction.
Durch die vorgeschlagene Maßnahme wird in vorteilhafter Weise sichergestellt, daß während der einzelnen Waschgutverteilungszyklen bzw. -maßnahmen durch das Programmschaltwerk keine Schleuderzeitschritte abgearbeitet werden und damit die vorgegebene Schleuderzeit für das Schleudergut auch ungekürzt zur Verfügung steht.The proposed measure advantageously ensures that no spin cycle steps are processed by the program switching mechanism during the individual laundry cycle or measures, and thus the predetermined spin time for the spin cycle is also available in full.
An Hand eines Blockschaltplanes wird die Erfindung nachfolgend näher erläutert.The invention is explained in more detail below on the basis of a block diagram.
Mit 1 ist ein mechanisches Programmschaltwerk bezeichnet, wie es für Waschmaschinen mit angetriebener Wasch- und Schleudertrommel zum Einsatz kommt. Das Programmschaltwerk (1) besitzt eine übliche Programmtrommel (2) zum Betätigen von Programmkontakten (3), die über einen zugehörigen Antriebsmotor (4) in Umlauf gebracht wird. Ein Antriebsmotor für die Wasch- und Schleudertrommel der Waschmaschine ist mit (5) bezeichnet. Der vorgenannte Wasch- und Schleudertrommelantriebsmotor (5) und der Antriebsmotor (4) für die Programmtrommel (2) des Programmschaltwerkes (1) sind über je eine elektrische Leitung (7) bzw. (7') mit einem an sich bekannten digitalen Drehzahlregler (6) verbunden.1 with a mechanical program switching mechanism is designated, as it is used for washing machines with a driven washing and centrifuging drum. The program switching mechanism (1) has a conventional program drum (2) for actuating program contacts (3), which is brought into circulation via an associated drive motor (4). A drive motor for the washing and centrifuging drum of the washing machine is designated by (5). The aforementioned washing and centrifugal drum drive motor (5) and the drive motor (4) for the program drum (2) of the program switching mechanism (1) are each via an electrical line (7) or (7 ') with a digital speed controller known per se (6 ) connected.
Die Funktionsweise des digitalen Drehzahlreglers (6) ist die, daß der Antrieb (4) für die Programmtrommel (2) des Programmschaltwerkes (1) für die Dauer einer neuen Waschgutverteilung und/oder einer Waschgutverteilungsmessung und/oder während einer Waschgutverteilungskorrektur angehalten wird, d. h., daß die Steuereinheit des digitalen Drehzahlreglers (6) nur dann den Antriebsmotor (4) der Programmtrommel (2) ansteuert, wenn gerade keiner der vorgenannten drei Waschgutverteilungszyklen abläuft bzw. durchgeführt wird.The mode of operation of the digital speed controller (6) is that the drive (4) for the program drum (2) of the program switching mechanism (1) for the duration of a new laundry item distribution and / or one Detergent distribution measurement and / or stopped during a laundry distribution correction, that is to say that the control unit of the digital speed controller (6) only drives the drive motor (4) of the program drum (2) when none of the aforementioned three laundry distribution cycles is in progress or being carried out.
Claims (1)
- Washing machine with a motor-driven washing and spinning drum, with a driven mechanical programmer and an out-of-balance load monitoring device, which in the case of an excessive out-of-balance load of the washing and spinning drum reduces the drive speed of the drive motor or temporarily completely stops the latter for the purpose of re-distribution of the laundry, characterised in that the drive of the mechanical programmer is stopped for the duration of distribution of the laundry and/or for measuring the distribution of the laundry and/or for correcting the distribution of the laundry.
