Description
Steuereinrichtung für HaushaltsmaschinenControl device for household machines
Die Erfindung betrifft eine Steuereinrichtung für Haushaltsmaschinen, z.B. Elektroherde, Waschmaschinen, Geschirrspüler und dergleichen, die mit einem Wählschalter mit mehreren Schaltstufen ausgebildet sind. Bei den bisher bekannten Haushaltmaschinen wird der Wahlschalter im allgemeinen durch Hand auf die gewünschte Schaltstufe eingestellt, wonach dann ein automatischer Arbeitsablauf erfolgen kann« Dies erfordert, daß der häufig sehr raumgreifende Wahlschalter an einer Stelle im Maschinengehäuse untergebracht werden muß, die eine bequeme Bedienung ermöglicht. Diese für die Bedienung günstigen Stellen befinden sich zumeist am oberen Rand der Frontplatte in einem erheblichen Abstand zu den zu schaltenden Motoren und dergleichen, die im allgemeinen im unteren Gehäuseteil, meist im rückwärtigen Abschnitt, untergebracht sind. Da die Wahlschalter allgemein mit einer Vielzahl von Kontakten ausgerüstet sein müssen, so daß ein großer Verdrahtungsaufwand in Form von Kabelbäumen erforderlich ist. Oft bereitet jedoch auch der Einbau des meist großen Wahlschalters an einer Stelle Schwierigkeiten, die von außen her bequem für die . Schaltung zugänglich ist. Dies ist insbesondere dann der Fall, wenn, wie es häufig angestrebt wird, die Gehäuseabmessungen möglichstThe invention relates to a control device for household machines, e.g. electric stoves, washing machines, dishwashers and the like, formed with a selector switch with several switching stages are. In the household machines known so far, the selector switch generally set by hand to the desired switching level, after which an automatic work sequence can take place « This requires that the selector switch, which is often very extensive, must be accommodated at one point in the machine housing, which is a enables convenient operation. These locations, which are favorable for operation, are mostly on the upper edge of the front panel in a considerable distance from the motors to be switched and the like, which are generally housed in the lower part of the housing, mostly in the rear section. Since the selector switches generally must be equipped with a large number of contacts, so that a large amount of wiring in the form of cable harnesses is required. Often, however, the installation of the mostly large selector switch at one point also causes difficulties that are convenient for the outside world. Circuit is accessible. This is particularly the case when, as is often the case, the housing dimensions are as close as possible

klein, insbesondere möglichst schmal, gehalten werden sollen.should be kept small, in particular as narrow as possible.
Der Erfindung liegt daher die Aufgabe zugrunde, den Aufbau derartiger Haushaltsmaschinen zu vereinfachen und den Bedienungskomfort zu erhöhen, indem der Wahlschalter von den Bedienungselementen räumlich getrennt wird.The invention is therefore based on the object of simplifying the construction of such household machines and making them easier to use by physically separating the selector switch from the controls.
Gemäß der Erfindung wird diese Aufgabe dadurch gelöst, daß der Wahlschalter mit einem elektromotorischen oder elektromagnetischen Kraftantrieb gekuppelt ist, der über elektronische Sensortasten ansteuerbar ist. Derartige Sensortasten, wie sie heute z.B. bei Fernsehgeräten bereits üblich sind, besitzen zwei Elektroden, die beim Berühren mit dem Pinger mit einem endlichen Widerstand der Haut überbrückt werden, wodurch eine nachgeschaltete Elektronikschaltung in einen anderen Schaltzustand umschaltet.According to the invention, this object is achieved in that the selector switch with an electromotive or electromagnetic Power drive is coupled, which can be controlled via electronic sensor buttons. Such sensor buttons, As they are already common today in television sets, for example, have two electrodes that are activated when the pinger is touched a finite resistance of the skin can be bridged, whereby one downstream electronic circuit in another Switching status changes.
Durch diese elektronische Steuerung wird auch dem Trend des Einsatzes von Elektronik in Haushaltsgeräten Rechnung getragen, was als Verkaufsargument ins Gewicht fällt. In technischer Hinsicht ergibt sich ein wesentlicher Vorteil dadurch, daß der Wahlschalter an eine beliebige Stelle im Maschinengehäuse eingebaut werden kann, da eine direkte manuelle Betätigung des Wahlschalters nicht mehr notwendig ist.This electronic control also takes into account the trend towards the use of electronics in household appliances, what is important as a sales argument. In technical There is a significant advantage in that the selector switch is installed anywhere in the machine housing can be, since a direct manual operation of the selector switch is no longer necessary.
Wenn der Wahlschalter die Gestalt eines Drehschalters besitzt, ist dieser zweckmäßigerweise mit einem Getriebemotor versehen, der die sonst übliche Handbetätigung ersetzt und über die Sensortasten angesteuert wird. Durch die Elektronikschaltung wird der Motor zum Anlaufen gebracht und läuft dann so lange, bis ein mit umlaufender Kontakt in der gewünschten Programmstellung des Schalters diesen Vorgang wieder abschaltet. Pur Jede einzelne Programmtaste, die einer bestimmten SchaltstellungIf the selector switch is in the form of a rotary switch, this is expediently provided with a gear motor, which replaces the usual manual operation and via the Sensor buttons is controlled. The motor is started by the electronic circuit and then runs for as long as until a rotating contact in the desired program position of the switch switches this process off again. Pure Each individual program button that has a specific switch position

des Drehwahlsehalters zugeordnet ist, wird dann ein solcher Kontakt erforderlich· Diese Kontakte laufen auf konzentrischen -Bahnen einer Printplatte, wobei die Bahnen dann je nach Winkelstellung des Schalters entsprechend ausgebildet sind. Der Antrieb dieser Kontakte erfolgt dabei synchron mit der Bewegung des Wahlschalters durch den Motor.of the rotary selector switch is assigned, then becomes such a Contact required · These contacts run on concentric tracks on a printed circuit board, the tracks then depending are designed according to the angular position of the switch. These contacts are driven synchronously with the movement of the selector switch by the motor.
Es sind zwar Relaissteuerungen bekannt, bei denen die Betätigungstasten von den Netzschaltern der Relais räumlich getrennt aufgebaut sind. Gegenüber diesen Relaissteuerungen besitzt die Erfindung jedoch den Vorteil, daß die Verwendung eines Motor getriebenen Drehwahlschalters die Gesamtsteuerung wesentlich verbilligt. Dies trifft insbesondere für Waschmaschinen und ähnliche Maschinen zu, bei denen nicht nur ein Ein- und Ausschaltvorgang erforderlich ist, sondern für die verschiedenen Programme immer mehrere Kontakte benötigt werden. Dies kann bei einem Drehschalter mit einer Nockenwelle sehr preisgünstig erreicht werden.Relay controls are known in which the operating buttons are spatially separated from the power switches of the relays. Compared to these relay controls, the Invention, however, the advantage that the use of a motor-driven rotary selector switch, the overall control is essential cheaper. This applies in particular to washing machines and similar machines that do not only require switching on and off is required, but several contacts are always required for the various programs. This can can be achieved very inexpensively with a rotary switch with a camshaft.
Ein weiterer Vorteil der Erfindung liegt darin, daß lediglich die Elektronikschaltung mit den Programmtasten an der Bedienungsstelle angeordnet werden muß, wofür ein minimaler Raum ausreichend ist. Der Wahlschalter mit dem Motorantrieb kann an irgend einer geeigneten Stelle der Maschine untergebracht werden, zweckmäßigerweise in der Nähe der zu schaltenden Aggregate. Außerdem wird hierdurch dem Designer die Möglichkeit gegeben, das Bedienungspult nach rein ästhetischen Gesichtspunkten und Gesichtspunkten des Bedienungskomforts aufzubauen, ohne Rücksicht nehmen zu müssen auf irgendwelche Einbaubedingungen im Gehäuse.Another advantage of the invention is that only the electronic circuit with the program buttons on the control point must be arranged, for which a minimal space is sufficient. The selector switch with the motor drive can be accommodated at any suitable point on the machine, expediently near the one to be switched Aggregates. In addition, this gives the designer the opportunity to adjust the control panel from a purely aesthetic point of view and to set up aspects of ease of use without having to take any installation conditions into account in the housing.
Nach einer weiteren Ausgestaltung der Erfindung ist der jeweiligen Programmtaste eine Anzeigelampe zugeordnet, die in der Taste oder auch benachbart zur Taste angeordnet werden kann.According to a further embodiment of the invention, the respective Program key assigned an indicator lamp that can be arranged in the key or adjacent to the key.

Gemäß einer weiteren Ausgestaltung der Erfindung kann zum Antrieb des Wahlschalters auch ein Hubmagnet als Kraftantrieb verwendet werden. Dieser Hubmagnet kann die Nockenwelle schrittweise über ein geeignetes Schaltrad jeweils um einen Schritt weiterdrehen.According to a further embodiment of the invention, a lifting magnet can also be used as a power drive to drive the selector switch be used. This lifting magnet can move the camshaft step by step using a suitable ratchet wheel turn one step further.
Anstelle des Wahlschalters kann auch ein kontinuierlich einstellbarer Regler, beispielsweise in Gestalt eines Thermostaten oder eines impulsgesteuerten Energiereglers Anwendung finden. Hierbei müßte die stufenlose Einstellung durch die Aufteilung in verschiedene Programmstufen über die Tastatur ersetzt werden.Instead of the selector switch, a continuously adjustable switch can also be used Regulator, for example in the form of a thermostat or a pulse-controlled energy regulator application Find. The stepless setting would have to be made by dividing the program into different program levels via the keyboard be replaced.
Gemäß einer Ausgestaltung der Erfindung kann für jedes Programm eine Taste mit Anzeigelampe vorgesehen werden. Stattdessen kann auch eine einzige Taste Anwendung finden, der eine Digitalanzeige für die jeweilige Programmwahl zuzuordnen ist und die entsprechend der Programmzahl mehrmals berührt werden muß oder solange berührt bleiben muß, bis das gewünschte Programm in der Digitalanzeige erscheint.According to one embodiment of the invention, a button with an indicator lamp can be provided for each program. Instead of this A single button can also be used to assign a digital display for the respective program selection and which must be touched several times according to the number of programs or must remain touched until the desired The program appears in the digital display.
