Jedes Gerät ist damit auf eine bestimmte Gesamtleistungs­ aufnahme festgelegt.The simultaneous operation of two electrical household appliances ten, e.g. B. washing machine and tumble dryer, übli usually over two separate circuits or power lines. The Resilience for each circuit or for each power line to max. 16 amps limited and also accordingly chert. Each device is therefore on a certain total output recording determined.

Bei einem aus dem DE-GM 16 83 534 bekannten Elektroherd, bei dem eine Unterteilung in primäre und sekundäre Verbraucher vorgenom­ men ist, wird die Energiezufuhr zu den sekundären Verbrauchern während der Unterbrechung der Energieaufnahme der primären Ver­ braucher durch eine thermische Steuereinrichtung freigegeben.In a known from DE-GM 16 83 534 electric stove, in which a division into primary and secondary consumers is the energy supply to the secondary consumers during the interruption of the energy consumption of the primary ver released by a thermal control device.

Aus dem Buch "Elektrische Geräte für Haushalt und Gewerbe", 1958, S. 44-45, ist es bei einem Elektroherd mit mehreren elektrischen Verbrauchern be­ kannt, durch eine Verriegelungsschaltung sicherzustellen, daß beim gleichzeitigen Einschalten mehrerer Verbraucher der zulässi­ ge Gesamtanschlußwert nicht überschritten wird.It is from the book "Electrical Appliances for Household and Business", 1958, pp. 44-45 in an electric cooker with several electrical consumers knows to ensure by a locking circuit when switching on several consumers of the permissible total connected load is not exceeded.

Weiterhin ist aus der Patentanmeldung DE-PAN P 5693 D, bek. gem. am 13.3.52, eine Schaltungsan­ ordnung für Stromverbrauchsgeräte, welche an eine gemeinsame Stromführung angeschlossen sind, bekannt, die nur ein wechselwei­ ses Einschalten der einzelnen Geräte mit voller Anschlußleistung zuläßt. Furthermore, from patent application DE-PAN P 5693 D, known. acc. on 13.3.52, a circuit regulation for power consumption devices which are connected to a common Power supply are connected, known that only one alternate Switching on the individual devices with full connected load allows.  

In der Zeitschrift "Der Anschluß" vom September 1968, S. 15 ist ein Stromrelais einer Vorrangschaltung für einen elektrischen Durchlauferhitzer mit einem Wärmespeicher-Heizgerät beschrieben, das beim Einschalten des Durchlauferhitzers anspricht und über einen Steuerkontakt das Aufladeschütz des Wärmespeicher- Heizgerätes abschaltet.In the magazine "Der Anschluss" from September 1968, p. 15 is a current relay of a priority circuit for an electrical Continuous-flow heater described with a heat storage heater, that responds when the instantaneous water heater is switched on and over a control contact the charging contactor of the heat storage Heater switches off.

Keine dieser bekannten Schaltungsanordnungen ist jedoch für zwei separat betreibbare Haushaltsgeräte, vor allem nicht für eine Waschmaschine und einen Wäschetrockner mit je einem Haupt- und einem Nebenverbraucher zum gleichzeitigen Betrieb beider Geräte geeignet.However, none of these known circuit arrangements is for two separately operated household appliances, especially not for one Washer and dryer, each with a main and a secondary consumer for the simultaneous operation of both devices suitable.

Der Erfindung liegt deshalb die Aufgabe zugrunde eine Steuerein­ heit zu schaffen, um bei Vorhandensein von nur einer Netzleitung trotzdem einen gleichzeitigen Betrieb von Waschmaschine und Trom­ melwäschetrockner zu ermöglichen.The invention is therefore based on the object a Steuerein to create in the presence of only one power line nevertheless a simultaneous operation of washing machine and power to enable the tumble dryer.

Die Lösung dieser Aufgabe gemäß der Erfindung ist dem Patentanspruch 1 zu entnehmen.This object is achieved according to the invention Claim 1 can be seen.

Anhand eines in der Zeichnung dargestellten Ausführungsbeispieles wird die Erfindung nachfolgend näher erläutert.Using one shown in the drawing The invention is an exemplary embodiment explained in more detail below.

Die Zeichnung zeigt eine Schalteinrichtung für eine Waschmaschine 1 als Gerät erster Priorität und einen Trommelwäschetrockner 2 als Gerät mit zweiter Priorität. Die Waschmaschine 1 hat als elektrischen Hauptverbraucher eine Heizeinrichtung 3 und als Nebenverbraucher einen Antriebsmotor 4 für deren Waschtrommel. In Reihe mit der Heizeinrichtung 3 ist ein üblicher Temperaturwächter 6 oder dergleichen geschaltet. Desgleichen hat der Trommelwäschetrockner 2 als Hauptverbraucher eine Heizeinrichtung 7 mit in Reihe dazu geschalteten Temperaturwächter 8 und als Nebenverbraucher ebenfalls einen Antriebsmotor 9 für dessen Wäschetrommel. Mit 10 ist eine elektrische Steuereinheit bezeichnet, die ein Stromrelais 11 und einen von diesem schaltbaren Kontakt 12 enthält. Die Steuereinheit 10 ist mit einem Stromeingang 13 an eine Netzleitung 14 angeschlossen, die mit 16 Ampere abgesichert ist. Ferner hat die Steuereinheit 10 zwei elektrische Ausgänge 15 und 16. An dem einen Ausgang 15 ist die Heizeinrichtung 3 (Hauptverbraucher) und der Antriebsmotor 4 (Nebenverbraucher) der Waschmaschine sowie der Antriebsmotor 9 (Nebenverbraucher) des Trommelwäschetrockners und am anderen Ausgang 16 ist nur die Heizeinrichtung 7 (Hauptverbraucher) des Trommelwäschetrockners angeschlossen. Der bereits erwähnte, vom Stromrelais 11 betätigbare Kontakt 12 der Steuereinheit 10 ist in Reihe mit der Heizeinrichtung 7 (Hauptverbraucher) des Trommelwäschetrockners geschaltet, während das Stromrelais 11 mit dem Antriebsmotor 4 und der Heizeinrichtung 3 (Haupt- u. Nebenverbraucher) der Waschmaschine bzw. dem Antriebsmotor 9 (Nebenverbraucher) des Trommelwäschetrockners eine Reihenschaltung bildet.The drawing shows a switching device for a washing machine 1 as a device with first priority and a drum dryer 2 as a device with second priority. The washing machine 1 has a heating device 3 as the main electrical consumer and a drive motor 4 for its washing drum as the secondary consumer. A standard temperature monitor 6 or the like is connected in series with the heating device 3 . Likewise, the tumble dryer 2 has as the main consumer a heating device 7 with temperature monitors 8 connected in series and as a secondary consumer also a drive motor 9 for its laundry drum. 10 denotes an electrical control unit which contains a current relay 11 and a contact 12 which can be switched by it. The control unit 10 is connected with a current input 13 to a power line 14 which is fused with 16 amps. The control unit 10 also has two electrical outputs 15 and 16 . At one output 15 , the heating device 3 (main consumer) and the drive motor 4 (secondary consumer) of the washing machine and the drive motor 9 (secondary consumer) of the tumble dryer and at the other output 16 , only the heating device 7 (main consumer) of the tumble dryer is connected. The aforementioned contact 12 of the control unit 10, which can be actuated by the current relay 11, is connected in series with the heating device 7 (main consumer) of the tumble dryer, while the current relay 11 with the drive motor 4 and the heating device 3 (main and secondary consumers) of the washing machine or the drive motor 9 (secondary consumer) of the tumble dryer forms a series connection.

Die Leitungsaufnahme der elektrischen Komponenten der Waschmaschine und des Trommelwäschetrockners sind so aufeinander abgestimmt, daß die Stromaufnahme des Hauptverbrauchers (Heizeinrichtung 3 bzw. 7) eines der Geräte zusammen mit den Nebenverbrauchern (Antriebsmotor 4 und 9) beider Geräte 16 Ampere nicht übersteigt.The line consumption of the electrical components of the washing machine and the tumble dryer are coordinated so that the current consumption of the main consumer (heating device 3 or 7 ) of one of the devices together with the secondary consumers (drive motor 4 and 9 ) of both devices does not exceed 16 amperes.

Die Arbeitsweise der beschriebenen Schalteinrichtung nach der Zeichnung ist nun folgende:The operation of the switching device described according to the drawing is now the following:

Es wird angenommen, daß beide Geräte 1 und 2 mit Wäsche beladen und eingeschaltet sind. Die Waschmaschine 1 als Gerät erster Priorität wird über die Netzleitung 14 mit Spannung versorgt, d. h., die Heizeinrichtung 3 (Hauptverbraucher) und der Antriebsmotor 4 (Nebenverbraucher) liegen beide an Spannung. Beim Trommelwäschetrockner als Gerät zweiter Priorität liegt lediglich der Antriebsmotor 9 (Nebenverbraucher) am Stromversorgungsnetz. Der vom Stromrelais 11 betätigbare Kontakt 12 der Steuereinheit 10 befindet sich in Offenstellung, wodurch die Heizeinrichtung 7 (Hauptverbraucher) des Trommelwäschetrockners stromlos bleibt. Spricht nun der in Reihe mit der Heizeinrichtung 3 der Waschmaschine liegende Temperaturwächter 6 an, so wird diese (Hauptverbraucher des Gerätes erster Priorität) vom Versorgungsnetz getrennt. Dies hat zur Folge, daß das Stromrelais 11 der Steuereinheit 10 anspricht und den Kontakt 12 in Schließstellung schaltet. Dadurch wird die Heizeinrichtung 7 (Hauptverbraucher) des Trommelwäschetrockners (Gerät mit der zweiten Priorität) ans Netz geschaltet. Der Antriebsmotor 4 der Waschmaschine und der Antriebsmotor 9 des Trommelwäschetrockners liegen unabhängig vom jeweiligen Schaltzustand des Stromrelais 11 über die Steuereinheit 10 immer an Spannung. Schaltet nun der Temperaturwächter 6 die Waschmaschinen-Heizeinrichtung 3 (Hauptverbraucher) wieder ein, so wird gleichzeitig über das Stromrelais 11 durch Umschalten des Kontaktes 12 die Heizeinrichtung 7 des Trommelwäschetrockners wieder vom Netz getrennt, während der Antriebsmotor 9 des Trommelwäschetrockners zusammen mit den beiden Verbrauchern 3 u. 4 der Waschmaschine weiter betrieben wird.It is assumed that both devices 1 and 2 are loaded with laundry and switched on. The washing machine 1 as a device of first priority is supplied with voltage via the mains line 14 , ie the heating device 3 (main consumer) and the drive motor 4 (secondary consumer) are both live. In the case of the tumble dryer as a second priority device, only the drive motor 9 (secondary consumer) is connected to the power supply network. The contact 12 of the control unit 10 which can be actuated by the current relay 11 is in the open position, as a result of which the heating device 7 (main consumer) of the tumble dryer remains currentless. If the temperature monitor 6 in line with the heating device 3 of the washing machine responds, then this (main consumer of the device of first priority) is disconnected from the supply network. The result of this is that the current relay 11 of the control unit 10 responds and switches the contact 12 into the closed position. As a result, the heating device 7 (main consumer) of the tumble dryer (device with the second priority) is connected to the network. The drive motor 4 of the washing machine and the drive motor 9 of the tumble dryer are always live regardless of the respective switching state of the current relay 11 via the control unit 10 . If the temperature monitor 6 now switches on the washing machine heating device 3 (main consumer) again, the heating device 7 of the drum clothes dryer is simultaneously disconnected from the mains via the current relay 11 by switching the contact 12 , while the drive motor 9 of the drum clothes dryer together with the two consumers 3 u. 4 the washing machine continues to operate.
