A control arrangement for domestic electrical apparatuses, such as dryers, washing machines or the like, having a heating device (5) and having a temperature-dependent switching device (6) which controls the heating device (5). In order to let the user of the apparatus know automatically if defective operating modes occur, a display device (7, 8), which is provided with means for storing its switching state, is placed in the circuit of the heating device (5) in parallel with the temperature-dependent switching device (6). <IMAGE>

Description

Steuerungsanordnúng für - -elektrische Haushaltsgeräte Control arrangement for - -electric household appliances

Die Erfindung betrifft eine Steuerungsanordnung für elektrische Haushaltsgeräte nach dem Oberbegriff des Patentanspruches 1.The invention relates to a control arrangement for electrical household appliances according to the preamble of claim 1.

Bei einer Vielzahl von elektrisch beheizten Haushaltsgeräten, wie z.B. Wäschetrockner, Wasch- und Geschirrspülmaschinen sind einerseits ein Thermostat, welcher die Einhaltung einer bestimmten Betriebstemperatur regelt, und andererseits eine Überhitzungsschutz-Ein richtung vorgesehen, die bei Ausfall des Thermostaten oder bei Überhitzung aus anderen Betriebsursachen die Stromzufuhr abschaltet bzw. unterbricht, bevor die Heizeinrichtung, was in der Regel ein Mantelrohrheizkörper ist, auf eine unzulässig oder gefährliche Temperatur kommt. Durch diese Einrichtungen wird zwar die Überschreitung unzulässiger Temperaturen beim betreffenden Gerät verhindert, der Benutzer jedoch erhält damit noch keinen Hinweis, daß sich das Gerät in einem gestörten Betriebszustand befindet. Die Folge davon ist, daß die Suche nach möglichen Fehlerquellen, die oftmals vom Benutzer selbst erkannt und ohne Einschaltung eines Kundendienstes auch abgestellt werden könnten, unterbleibt. Solche Fehlerquellen können z.B. bei einem Haushalts-Wäschetrockner das nicht richtige Verlegen des Abluftschlauches, das Verstellen der Abluftöffnungen, ein Verstopfen des Flusensiebes oder eine Überladung der Wäschetrommel sein.In a variety of electrically heated household appliances, such as E.g. clothes dryers, washing machines and dishwashers are on the one hand a thermostat, which regulates the maintenance of a certain operating temperature, and on the other hand an overheating protection device is provided in the event of a thermostat failure or in the event of overheating for other operational reasons, switch off or switch off the power supply. interrupts before the heating device, which is usually a tubular heater comes to an impermissible or dangerous temperature. Through these bodies Exceeding impermissible temperatures is prevented on the device in question, However, the user does not receive any indication that the device is in a disturbed operating state. The consequence of this is that the search for possible Sources of error that are often recognized by the user himself and without the involvement of a Customer service could also be turned off. Such sources of error incorrect routing of the exhaust air hose, e.g. in a household tumble dryer, Adjusting the exhaust air openings, clogging the lint filter or overloading be the laundry drum.

Aufgabe der Erfindung ist es daher, eine Steuerungsanordnung für ein elektrisches Haushaltsgerät so weiterzubilden, daß bei gestörten Betriebszuständen der Benutzer automatisch darauf aufmerksam gemacht wird.The object of the invention is therefore to provide a control arrangement for a electrical Household appliance so that when disturbed Operating states of the user is automatically made aware of it.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem kennzeichnenden Teil des Patentanspruches 1 zu entnehmen.The solution to this problem according to the invention is the characteristic one Part of claim 1 can be found.

Durch die Erfindung wird in vorteilhafter Weise erreicht, daß der Benutzer eines solcher Art ausgerüsteten Gerätes bei unzulässigen bzw. kritischen Be triebszuständen automatisch einen entsprechenden Hinweis erhält. Durch entsprechende Überprüfung des Gerätes durch den Benutzer können dann Fehler quellen, die evtl in der falschen Geräteaufstellung oder Bedienung ihre Ursache haben, vom Benutzer festgestellt und ohne Einschaltung eines Kundendienst von diesem auch selbst behoben bzw. beseitigt werden.By the invention it is achieved in an advantageous manner that the Users of such a device equipped with impermissible or critical Operating states automatically receives a corresponding notification. Through appropriate Checking the device by the user can then cause errors caused by incorrect installation or operation of the device by the user and rectified it himself without engaging a customer service or eliminated.

Ein Ausführungsbeispiel der Erfindung wird nachfolgend an Hand einer Schaltung näher erläutert. Das Ausführungsbeispiel ist dabei auf den Stromlaufplan eines elektrischen Haushalts-Wäschetrockners abgestellt.An embodiment of the invention is based on a Circuit explained in more detail. The exemplary embodiment is on the circuit diagram a household electric tumble dryer turned off.

Von einem Netzsteckeranschluß 1,2 fließt Strom über einen Hauptschalter 3 zu den einzelnen Verbrauchern des Haushaltsgerätes, welches im vorliegenden Falle ein Wäschetrockner ist. Als ein Teil der Verbraucher kommen dabei z.B. der Antriebsmotor sowie die Programmsteuerung in Frage, die nur schematisch angedeutet und mit 4 bezeichnet sind. Ein weiterer Verbraucher ist eine Heizeinrichtung 5, in deren Stromweg eine temperaturabhängige Schalteinrichtung 6 gelegt ist sowie eine Anzeigevorrichtung 7 mit Anzeigelampe 8. Von der Anzeigevorrichtung 7 führt eine zusätzliche Leitung 9 zu einem Anschluß-Punkt 10 im Stromkreis der temperaturabhängigen Schalteinrichtung 6. Über diese Leitung wird die Spannung de r te der temperaturabhängigen Schalteinrichtung 6 abgefühlt. Führt nun ein Überschreiten der Temperatur im Gerät (Wäschetrockner) zum Ansprechen und damit Öffnen der temperaturabhängigen Schalteinrichtung 6, wird zunächst die Stromzufuhr zur Heizeinrichtung 5 unterbrochen. Gleichzeitig tritt zwischen dem bereits genannten Anschluß--Punkt 10 und einem weiteren, im Stromkreis der Schalteinrichtung 6 befindlichen Anschluß-Punkt 11 eine Spannung auf, die ein Ansprechen der durch die Anschluß-Punkte 10,11 parallel zur Schalteinrichtung 6 geschalteten Anzeigevorrichtung 7 auf, was ein Aufleuchten von deren Anzeigelampe 8 zur Folge hat. Dem Benutzer wird damit beim beschriebenen Ausführungsbeispiel optisch angezeigt, daß die temperaturabhängige Schalteinrichtung 6 angesprochen hat. Damit die optische Anzeige auch dann erhalten bleibt, wenn die offene temperaturabhängige Schalteinrichtung 6 noch vor Ende des Programmablaufes wieder in ihre Schließstellung zurückfällt, sind in der Anzeigevorrichtung 7 Mittel zur Speicherung ihres Schaltzustandes vorgesehen. Solche Mittel können z.B. Selbsthalteschaltungen mit Relais oder Multivibratoren sein.Current flows from a mains plug connection 1, 2 via a main switch 3 to the individual consumers of the household appliance, which in the present case is a clothes dryer. The drive motor, for example, is part of the consumers and the program control in question, which is only indicated schematically and denoted by 4 are. Another consumer is a heating device 5, in whose current path a temperature-dependent switching device 6 is placed and a display device 7 with indicator lamp 8. An additional line leads from the indicator device 7 9 to a connection point 10 in the circuit of the temperature-dependent switching device 6. The voltage de r te of the temperature-dependent switching device is transmitted via this line 6 sensed. If the temperature in the device (tumble dryer) is exceeded to respond and thus open the temperature-dependent switching device 6, is initially the power supply to the heating device 5 is interrupted. At the same time occurs between the aforementioned connection point 10 and another one in the circuit the switching device 6 located connection point 11 a voltage on which a response by the connection points 10,11 parallel to the switching device 6 switched on display device 7, which means that its indicator lamp lights up 8 results. The user is thus in the described embodiment visually indicated that the temperature-dependent switching device 6 addressed Has. So that the visual display is retained even if the open temperature-dependent Switching device 6 into its closed position again before the end of the program sequence falls back, means are in the display device 7 for storing its switching state intended. Such means can, for example, be self-holding circuits with relays or multivibrators be.
