Abstract

A modification to the circuity of a domestic linen dryer which has an electronic control system, together with a humidity control and a step sequence circuit, eliminates the inconvenience arising from the precautions for the safety of children. When the program is interrupted by the opening of the door, as happens if it is desired to put in more linen, the program stored is cancelled and the step sequence circuit is set back to start. On pressing the start button once, the sequence circuit is run through rapidly to the point at which it was interrupted, and the remaining steps can only be completed after a delay. If during this period of delay the program is reselected, it restarts at the same point without the delay of the sequence being run through.

Description

Verfahren zur Steuerung des Programmablaufs Procedure for controlling the program sequence

eines Wäschetrockners Die Erfindung bezieht sich auf ein Verfahren zur Steuerung des Programmablaufs eines Wäschetrockners, der eine elektronische Programmsteuereinrichtung in Verbindung mit einer Feuchtesteuerung und ein Schrittsteuerwerk aufweist. of a clothes dryer The invention relates to a method to control the program sequence of a tumble dryer that has an electronic Program control device in connection with a humidity control and a step control unit having.

Bei den Trocknern der vorgenannten Art ist es aus Sicherheitsgründen notwendig, daß bei Unterbrechung während des Programmablaufs durch Öffnen der Tür das in der elektronischen Programmsteuereinrichtung gespeicherte Programm gelöscht wird und daß das Sohrittsteue rwe rk wieder in die startbereite Anfangsposition fährt. HIerdurch soll unter dem Gesichtspunkt der Kindersicherheit vermieden werden, daß das Kind in die Wäsche trommel steigen kann und durch Zuziehen der Tür den Trockner wieder in Gang setzen kann.In the case of dryers of the aforementioned type, it is for safety reasons necessary that if the program is interrupted by opening the door the program stored in the electronic program control device is deleted and that the Sohrittsteue rwe rk back to the start-ready starting position moves. This is to avoid, from the point of view of child safety, that the child can get into the laundry drum and the dryer by closing the door can start again.

Durch die vorbeschriebene Sicherheitsmaßnahme entsteht für den Benutzer des Trockners ein Bedienungsnachteil, und zwar wenn das bereits angelaufen Trockenprogramm gewollt unterbrochen wird, um noch Wäschestücke nachzulegen. In diesem Fall muß nun erst abgewartet werden bis die Programmschalteinrichtung das restliche Programm überfahren hat und wieder für eine erneute Anwahl bereit ist. Obwohl dieser Vorgang in einem Schnellgang durchgeführt wird, kommt es doch zu einer lästigen Wartezeit.The safety measure described above arises for the user of the dryer is an operating disadvantage, namely when the drying program has already started is deliberately interrupted in order to add more items of laundry. In this case must now wait until the program switching device carries out the rest of the program has run over and is ready to be selected again. Although this process is carried out at a rapid pace, there is an annoying waiting time.

Der Erfindung liegt die Aufgabe zugrunde, den vorbeschriebenen Nachteil zu vermeiden und ein Verfahren zur Steuerung des Programmablaufs eines Wäschetrockners zu offenbaren bei dem trotz Einhaltung der entsprechenden Sicherheitsbestimmungen die Bedienungsfreundlichkeit des Trockners verbessert wird.The invention is based on the above-described disadvantage to avoid and a method for controlling the program sequence of a tumble dryer to be revealed in spite of compliance with the relevant safety regulations the ease of use of the dryer is improved.

Die Lösung dieser Aufgabe wird dadurch erreicht, daß durch Öffnen der Trocknertür während des laufenden Programms das in der elektronischen Programmsteuereinrichtung gespeicherte Programm gelöscht wird, daß die Weiterschaltung der Schrittsteuerung in den Schnellgang zum Überfahren der restlichen Programmschritte erst nach einer zeitlichen Verzögerung erfolgen kann und daß bei erneuter Programmanwahl innerhalb dieser zeitlichen Verzögerung das Programm an gleicher Stelle fortgesetzt wird, ohne daß die Schrittsteuerung in den Schnellgang fährt.The solution to this problem is achieved by opening the dryer door while the program is running that in the electronic program control device stored program is deleted that the step control is continued into high speed to run through the remaining program steps only after one time delay can take place and that with renewed program selection within this time delay the program is continued at the same point, without the step control going into overdrive.

Weitere Merkmale der Erfindung sind, daß die zeitliche Verzögerung vor Übergang in den Schnellgang nur in den feuchtigkeitsabhängig gesteuerten Trocknungswahlstufen wirksam ist.Further features of the invention are that the time delay before switching to overdrive, only in the moisture-dependent controlled drying selection levels is effective.

und zeitabhingig Durch das erfindungsgemäße Verfahren wird bei einem Wäschetrockner mit einer einfachen, schaltungstechnisch leicht zu realisierenden Maßnahme die Bedienungsfreundlichkeit des Gerätes verbessert, ohne daß dabei die Sicherheitsvorkehrungen vernachlässigt werden. and time-dependent By the method according to the invention is easy to do in terms of circuitry in a tumble dryer with a simple circuit implementing measure improves the user-friendliness of the device without that the safety precautions are being neglected.

Nachstehend soll das erfindungsgemäße Verfahren anhand einer bevorzugten Prograrr msteuerung für einen Trockner erläutert werden, wobei die wesentlicht Elemente der Programmsteuerung von einem mechanischen Schrittschaltwerk und einer elektronischen Steuereinheit gebildet werden. Die elektronische Steuereinheit enthält die Speicherung der möglichen Programmschritte und in Verbindung mit einer feuchtigkeitsabfragenden Steuerschaltung werden die Befehle zur Schrittausführung an das Schrittschaltwerk gegeben.In the following, the method according to the invention will be based on a preferred Program control for a dryer will be explained, with the essential elements the program control of a mechanical stepping mechanism and an electronic one Control unit are formed. The electronic control unit contains the storage of the possible program steps and in connection with a moisture query Control circuit are the commands for step execution to the stepping mechanism given.

Bei einem feuchtigkeitsabhängig gesteuerten Trockenprogramm wird der Feuchte anteil in der Wäsche laufend abgefragt, und der augenblickliche Trocknungsgrad.With a humidity-controlled drying program, the The amount of moisture in the laundry is continuously queried and the current degree of drying.

der Wäsche kann über elektronische Mittel auf der Schalterblende zur Anzeige gebracht werden. Will nun der Benutzer das Programm gewollt unterbrechen, z. B. um noch Wäscheteile nachzulegen oder empfindliche Wäscheteile vorzeitig aus der Trommel zu entnehmen, wird gleichzeitig mit der Türöffnung das in der elektronischen Steuereinheit vorprogrammierte Trocknungsprogramm gelöscht. Das mechanische Schrittschaltwerk bleibt aber noch für eine bestimmte Zeit (z. B. 5 Sekunden) in dem gleichen Schritt stehen.the laundry can be done electronically on the switch panel Display will be brought. If the user wants to interrupt the program intentionally, z. B. to refill items of laundry or to remove sensitive items of laundry prematurely removed from the drum, the electronic one is opened at the same time as the door is opened Control unit's preprogrammed drying program deleted. The mechanical stepping mechanism but remains in the same step for a certain time (e.g. 5 seconds) stand.

Innerhalb dieser Zeit kann der Benutzer das Programm durch entsprechende Anwahl bei geschlossener Tür erneut starten und das Schrittschaltwerk setzt an gleicher Stelle das Programm fort. Dadurch wird das lästige Warten vermieden, bis das Schrittschaltwerk im Schnellgang die restlichen Programmschritte überfahren hat.Within this time, the user can run the program through appropriate Start the selection again with the door closed and the step-by-step switch continues Continue the program. This avoids the annoying waiting for the stepping mechanism has passed the remaining program steps at high speed.

Bei mißbräuchlicher Türöffnung durch Kinder dagegen wird nach Ablauf der Verzögerungszeit das Trockungsprogramm aufgehoben und das Schrittschaltwerk fährt in die Stop-Position. Man kann davon ausgehen, daß in diesem Fall eine erneute Programmanwahl innerhalb der möglichen Verzögerungszeit von Kindern nicht vorgenommen wird.If the door is opened improperly by children, on the other hand, it will expire the delay time, the drying program is canceled and the stepping mechanism moves to the stop position. One can assume that in this case another Program selection not made by children within the possible delay time will.
