Abstract

Program controlled laundry drier has a cycle where initially the drum section is filled with a given volume of water, and the drum is rotated at a higher speed than the normal rate, so that the water is carried up by the ribs at the drum edge to a height of about \3 of the washing chamber diameter. The water is then emptied.

Description

Die Erfindung betrifft einen programmgesteuerten Waschtrockner mit einem Laugenbehälter, in dem eine Trommel zur Aufnahme von Wäsche drehbar gelagert ist, mit einem zwischen zwei Öffnungen des Laugenbehälters angeordneten Prozeßluft- und Kondenskanal und mit Bedien­ elementen zur Anwahl von Wasch-, Trocken- und Sonderprogrammen, wobei mit einem Bedienelement ein von einem Wasch- oder Trockenprogramm unabhängig durchführbares Programm zum Ausspülen von Flusen wählbar ist.The invention relates to a program-controlled washer dryer with a tub, in which a drum for receiving laundry is rotatably mounted, with one between two Openings of the tub arranged process air and condensation channel and with operator elements for the selection of washing, drying and special programs, with one Control element that can be carried out independently of a washing or drying program Program for rinsing out fluff is selectable.

Ein solcher Waschtrockner ist aus der DE 43 03 655 A1 bekannt. Bei Waschtrocknern können sich während des Trocknungsprozesses im Prozeßluft- und Kondenskanal Flusen festsetzen. Diese lagern sich in den folgenden Trocknungsprogrammen an der neu eingefüllten Wäsche ab und stellen insbesondere bei andersfarbigen Textilien eine Verschmutzung dar. Um dies zu vermeiden, ist es bekannt, den von der Verflusung besonders stark betroffenen Kondenskanal zu spülen. Dabei kann es vorkommen, daß sich die aus dem Kondenskanal gespülten Flusen auf dem Weg durch den Laugenbehälter zum Abfluß an den Laugenbehälterwänden, an der Außenseite der Trommel und durch Verschleppung in den folgenden Waschprogrammen sogar an der Tür festsetzen.Such a washer dryer is known from DE 43 03 655 A1. With washer dryers lint build up in the process air and condensation duct during the drying process. In the following drying programs, these are deposited on the newly filled laundry and are particularly dirty with different colored textiles. To do this avoid, it is known, the condensation channel that is particularly badly affected by the condensation to wash. It can happen that the lint rinsed out of the condensation channel on the way through the tub to the drain on the tub walls, at the On the outside of the drum and even in the following washing programs fix on the door.

Der Erfindung stellt sich somit das Problem, bei einem Waschtrockner der eingangs genannten Art die Verschleppung von Flusen aus dem Kondenskanal in den Laugenbehälter und damit aus dem Trocknungsprozeß in den Waschprozeß zu verhindern.The invention thus presents the problem in a washer dryer of the type mentioned Kind of carryover of fluff from the condensation channel into the tub and thus to prevent from the drying process in the washing process.

Erfindungsgemäß wird dieses Problem durch einen programmgesteuerten Waschtrockner mit den im Patentanspruch 1 angegebenen Merkmalen gelöst. Vorteilhafte Ausgestaltungen und Weiterbildungen der Erfindung ergeben sich aus den nachfolgenden Unteransprüchen.According to the invention, this problem is solved by a program-controlled washer dryer solved the features specified in claim 1. Advantageous configurations and Further developments of the invention result from the following subclaims.

Die mit der Erfindung erreichbaren Vorteile bestehen darin, daß auf Wunsch des Benutzers eine vollständige Reinigung des Waschtrockners von Flusen vorgenommen werden kann und somit eine Verschleppung von Flusen von einer Wäsche zur nächsten vermieden wird.The advantages achievable with the invention are that at the request of the user a complete cleaning of the washer dryer from fluff can be done and this prevents the spread of fluff from one wash to the next.

Bei Waschtrocknern mit am Trommelmantel angeordneten Schöpfrippen, wovon die Erfindung auch Gebrauch macht, hat es sich als vorteil­ haft erwiesen, das Drehen der Trommel mit einer Drehzahl nF vorzunehmen, bei der das Wasser im Laugenbehälter von den Schöpfrippen bis zu einer Höhe von etwa 3/4 des Laugen­ behälter-Durchmessers mitgenommen wird. Hierdurch wird das Wasser nach Erreichen der gewünschten Höhe sehr stark verwirbelt und erreicht auf diese Weise auch die Stirnflächen, nämlich die Tür und die Trommel- bzw. Laugenbehälter-Rückwand. Bei einer Erhöhung der Drehzahl würde ein vollständiger, den Trommelmantel umgreifender Wassermantel ausgebildet werden und die Reinigung der Stirnflächen würde unterbleiben. Bei geringeren Drehzahlen würde eine Verwirbelung des Wassers nicht stattfinden. Bei handelsüblichen Haushalts-Wasch­ trocknern hat sich eine Drehzahl von ca. 250 min-1 als vorteilhaft erwiesen (Anspruch 5).In washer-dryers with scoop ribs arranged on the drum jacket, of which the invention also makes use, it has proven advantageous to carry out the rotation of the drum at a speed n F at which the water in the tub from the scoop ribs to a height of about 3 / 4 of the tub diameter. As a result, the water is swirled very strongly after reaching the desired height and in this way also reaches the end faces, namely the door and the drum or tub rear wall. If the speed were increased, a complete water jacket encompassing the drum jacket would be formed and the end faces would not be cleaned. At lower speeds, the water would not swirl. In commercial household washer dryers, a speed of approximately 250 min -1 has proven to be advantageous (claim 5).

Darüber hinaus ist es besonders vorteilhaft, wenn die Trommel in beiden Drehrichtungen ge­ dreht wird. Hierdurch erfolgt eine gleichmäßige Reinigung des gesamten Laugenbehälter- und Trommelbereichs (Anspruch 6).In addition, it is particularly advantageous if the drum ge in both directions of rotation is turning. This results in a uniform cleaning of the entire tub and Drum area (claim 6).

Es ist außerdem vorteilhaft, wenn die Trommel während des Entleerens des Laugenbehälters weiter gedreht wird. Hierdurch wird ein Absetzen der Flusen am Laugenbehälter-Mantel während des Entleerungsvorgangs vermieden (Anspruch 7).It is also advantageous if the drum is emptied while the tub is being emptied is rotated further. This will cause the lint to settle on the tub shell avoided during the emptying process (claim 7).

Ein Ausführungsbeispiel der Erfindung wird nachfolgend näher beschrieben. Der erfindungs­ gemäß ausgebildete Waschtrockner besitzt in bekannter Weise einen Laugenbehälter, in dem eine Trommel drehbar gelagert ist. Die Drehung der Trommel erfolgt über einen Antriebsmotor, die Regelung der Motordrehzahl über die Programmsteuerung, wobei vorteilhafterweise eine Mikroprozessor-Steuerung verwendet wird. Der Laugenbehälter ist im wesentlichen zylinder­ förmig ausgebildet und besitzt an seiner Vorderseite eine Entnahmeöffnung, die durch eine Tür verschlossen wird. Zum Trocknen wird im Bereich der Tür erwärmte Luft eingeleitet. Die Erwärmung und die anschließende Entfeuchtung der Trocknungsluft erfolgt in einer aus der DE 43 03 655 A1 bekannten Weise. Zur Verbesserung der Durchfeuchtung der Wäsche in den verschiedenen Waschprogrammen sind am Trommelmantel Schöpfrippen (siehe bspw. EP 0 304 391 A2) angeordnet.An embodiment of the invention is described in more detail below. The invention trained washer dryer has a tub in a known manner in which a drum is rotatably mounted. The drum is rotated by a drive motor, the regulation of the engine speed via the program control, advantageously a Microprocessor control is used. The tub is essentially cylindrical shaped and has a removal opening on its front, through a door is closed. Warmed air is introduced in the area of the door to dry. The Heating and the subsequent dehumidification of the drying air takes place in one of the DE 43 03 655 A1 known manner. To improve the moisture in the laundry Various washing programs have scoop ribs on the drum jacket (see e.g. EP 0 304 391 A2).

Der Waschtrockner besitzt ein Bedienfeld mit einem ersten Drehwahlschalter, mit dem Wasch­ programme nach Wäscheart und Temperatur eingestellt werden können. Darüber hinaus können mit diesem Drehwahlschalter selbsttätig ablaufende Sonderprogramme wie "Stärken", "Schleudern", "Pumpen" und "Flusen ausspülen" gewählt werden. Ein zweiter Drehwahlschalter dient zur Einstellungen von Trockenprogrammen, nach Wäschearten und Trocknungsgrad geordnet. Mit Drucktasten können Zusatzfunktionen ("Vorwäsche/Einweichen", "Kurz", "Schongang", "Wasser plus", "Trocknen/Temp. Niedrig"), Drehzahlen und eine Startvorwahl eingestellt werden.The washer dryer has a control panel with a first rotary selector switch, the wash programs can be set according to the type of laundry and temperature. Furthermore With this rotary selector switch, special programs such as "Strengths", "Spin", "Pump" and "Flush Fluff" can be selected. A second rotary selector switch is used to set drying programs, by type of laundry and degree of drying orderly. Additional functions ("Prewash / Soak", "Short", "Gentle cycle", "water plus", "drying / temp. Low"), speeds and a delay start can be set.

Die Funktion des Sonderprogramms "Flusen ausspülen" ist im folgenden beschrieben:
Nach der Anwahl des Programms werden 7,5 bis 8 Liter Wasser zeitgesteuert oder niveau­ gesteuert in den Laugenbehälter eingefüllt, so daß das Wasser in der Trommel einen Füllstand bis zum unteren Rand der Trommelöffnung erreicht. Dabei wird die Trommel mit Waschdreh­ zahl (ca. 50 min-1) gedreht. Anschließend wird die Trommel für ca. 60 Sekunden auf eine Dreh­ zahl nF von 250 min-1 beschleunigt. Dabei wird das Wasser im unteren Bereich des Laugenbe­ hälters von den Schöpfrippen der Trommel mitgerissen und bildet einen Wassermantel, der sich bis zu einer Höhe von 3/4 des Laugenbehälter-Durchmessers erstreckt. Durch das Zusam­ menbrechen des Wassermantels auf dieser Höhe entstehen Verwirbelungen, wodurch auch die Tür und die Trommel- und Laugenbehälter-Rückwand gereinigt werden. Nach Ablauf der 60 Sekunden erfolgt eine Pause von 5 Sekunden, in der die Trommel ausläuft. Anschließend erfolgt eine Drehrichtungsumkehr und eine erneute Beschleunigung der Trommel auf 250 min-1 für 60 Sekunden. Danach wird der Laugenbehälter unter weiterer Drehung der Trommel mit Waschdrehzahl (ca. 50 min-1) entleert.The function of the special program "Rinse out fluff" is described below:
After selecting the program, 7.5 to 8 liters of water are filled into the tub in a time-controlled or level-controlled manner so that the water in the drum reaches a level up to the bottom of the drum opening. The drum is rotated at the wash speed (approx. 50 min -1 ). The drum is then accelerated to a speed n F of 250 min -1 for approx. 60 seconds. The water of the Laugenbe hälters in the lower part is entrained by the scoop ribs of the drum, and forms a water jacket to a height of 3/4 of the tub diameter extends. The collapse of the water jacket at this level creates turbulence, which also cleans the door and the drum and tub rear wall. After the 60 seconds have elapsed, there is a pause of 5 seconds during which the drum runs out. The direction of rotation is then reversed and the drum is accelerated again to 250 min -1 for 60 seconds. Then the tub is emptied while rotating the drum at the washing speed (approx. 50 min -1 ).
