Der Vorwiderstand wird auf eine definierte Nennleistung des Elektromotors eingestellt. Bei Überschreiten der Nennleistung wird der Vorwider stand auf Temperaturen aufgeheizt, die schließlich zu einer Auslösung der Temperatursicherung und einer Un terbrechung der Stromzufuhr zum Elektromotor führen. Bei bekannten Fernsteueranordnungen der vorgenannten Art ist die Temperatursicherung innerhalb des Motor kreises in Reihe zum Motor angeordnet und wird dort im Betriebszustand vom Motorstrom durchflossen. Vor allem bei hohen Anschlußleistungen kann dies zu unerwünschten Aufheizungen und Fehlfunktionen der Temperatursicherung führen. Weiter wird die relativ große Bauweise der Tem peratursicherung bei großen Anschlußleistungen als nach teilig empfunden.The remote control arrangement according to the invention is in front especially for use in radiator and heater fans in the Vehicle construction determined. The series resistor is on a defined nominal power of the electric motor set. If the nominal power is exceeded, the series resistor becomes got heated up to temperatures that eventually too a triggering of the temperature fuse and an Un Disconnect the power supply to the electric motor. In known remote control arrangements of the aforementioned Type is the temperature fuse inside the motor circle arranged in series to the motor and is there in the Operating current flowed through by the motor current. Especially with high connected loads this can be undesirable Heating and malfunction of the temperature fuse to lead. The relatively large construction of the Tem temperature protection for large connected loads as after felt in part.
Ausgehend hiervon liegt der Erfindung die Aufgabe zu grunde, die Fernsteueranordnung der eingangs angegebe nen Art dahingehend zu verbessern, daß auch bei großen Motorleistungen eine zuverlässige Temperatursicherung mit geringem baulichen Aufwand möglich ist.Based on this, the object of the invention reasons, the remote control arrangement specified at the beginning NEN way to improve that even with large Motor performance a reliable temperature protection is possible with little construction effort.
Zur Lösung dieser Aufgabe wird gemäß der Erfindung vor geschlagen, daß die Temperatursicherung ein im Steuer stromkreis angeordnetes, thermisch auslösbares Schalt element aufweist. Das Schaltelement kann dabei als re versibler Schutzschalter mit thermischem Auslöser, ins besondere als Bimetallstreifen, oder als thermisch aus lösbares Halbleiterschaltelement ausgebildet sein. Al ternativ hierzu kann die Temperatursicherung auch als thermisch auslösbares, irreversibles Sicherungsorgan ausgebildet werden.To solve this problem, according to the invention struck that the thermal fuse is in control circuit arranged, thermally triggerable switch element. The switching element can be re flexible circuit breaker with thermal release, ins especially as bimetallic strips, or as thermal releasable semiconductor switching element can be formed. Al Alternatively, the temperature fuse can also be used as thermally triggered, irreversible security device be formed.
Die erfindungsgemäße Temperatursicherung wird vor allem bei der Fernsteuerung von Gleichstrommotoren, die mit hohen Stromstärken beaufschlagt werden, mit Vorteil eingesetzt.The temperature fuse according to the invention is above all in the remote control of DC motors with high currents are applied, with advantage used.
Beim Einsatz der Fernsteuerungsanordnung für Gebläse lüfter in Kraftfahrzeugen ist der Fernsteuerschalter zweckmäßig als auf die Kühlwassertemperatur eines Kraft fahrzeugs ansprechender Thermoschalter ausgebildet.When using the remote control arrangement for blowers The remote control switch is a fan in motor vehicles expedient than on the cooling water temperature of a force vehicle-trained thermal switch trained.
Nachstehend wird die Erfindung anhand eines in der Zeichnung in schematischer Weise dargestellten Ausfüh rungsbeispiels näher erläutert.The invention is based on one in the Drawing shown in a schematic manner example explained in more detail.
Die einzige Figur zeigt eine Schaltungsanordnung für die Fernsteuerung des Elektromotors für einen Heiz- und Gebläselüfter.The only figure shows a circuit arrangement for the remote control of the electric motor for a heating and Blower fan.
Die in der Zeichnung dargestellte Schaltungsanordnung umfaßt einen in einem Motorstromkreis 10 angeordneten Gleichstrommotor 12 und einen zu diesem in Reihe ge schalteten Vorwiderstand 14. Der Motorstromkreis 10 ist über den Schaltkontakt 16 eines Relais 18 mit einer als Akkumulator ausgebildeten Gleichstromquelle 20 verbind bar. Die Magnetspule 22 des Relais 18 befindet sich in einem Steuerstromkreis 24, der über einen vorzugsweise als Thermoschalter ausgebildeten Fernsteuerschalter 26 mit der Gleichstromquelle 20 verbindbar ist. Der Vorwi derstand 14 ist thermisch mit einer Temperatursicherung 28 gekoppelt, die ein im Steuerstromkreis 24 angeord netes, thermisch auslösbares Schaltelement 30 aufweist.The circuit arrangement shown in the drawing comprises a DC motor 12 arranged in a motor circuit 10 and a series resistor 14 connected in series with it. The motor circuit 10 is connected via the switch contact 16 of a relay 18 to a direct current source 20 designed as an accumulator. The magnet coil 22 of the relay 18 is located in a control circuit 24 which can be connected to the direct current source 20 via a remote control switch 26 , which is preferably designed as a thermal switch. The Vorwi resistor 14 is thermally coupled to a temperature fuse 28 which has a thermally triggerable switching element 30 arranged in the control circuit 24 .
Das Schaltelement 30 kann beispielsweise als reversib ler Schutzschalter mit thermischem Auslöser, insbeson dere als Bimetallstreifen ausgebildet sein. Es ist je doch auch möglich, den Schutzkontakt 30 als Halbleiter schaltelement, als temperaturabhängigen Widerstand oder als irreversibel durchschmelzendes Sicherungsorgan aus zubilden.The switching element 30 can be designed, for example, as a reversible circuit breaker with a thermal release, in particular as a bimetallic strip. However, it is also possible to form the protective contact 30 as a semiconductor switching element, as a temperature-dependent resistor or as an irreversibly melting fuse element.
Bei einer Betätigung des Fernsteuerschalters 26 wird die Magnetspule 22 des Relais 18 von einem Steuerstrom durchflossen und der Schaltkontakt 16 des Motorstrom kreises 10 entgegen der Kraft einer nicht dargestellten Feder geschlossen. Dadurch wird der Gleichstrommotor 12 in Gang gesetzt. Wird eine vorgegebene Nennleistung des Gleichstrommotors 12, auf die der Vorwiderstand 14 ab gestimmt ist, überschritten, so wird der Vorwiderstand 14 aufgeheizt, bis die Temperatursicherung 28 ausgelöst wird. In diesem Falle unterbricht das Schaltelement 30 den Steuerstromkreis 24. Dadurch fällt das Relais 18 ab, so daß auch der Motorstromkreis 10 über den Schalt kontakt 16 geöffnet wird. Da die Temperatursicherung nur von dem relativ kleinen Steuerstrom durchflossen wird, ist eine kleine Bauweise und ein zuverlässiger Betrieb gewährleistet.When the remote control switch 26 is actuated, a magnetic current flows through the solenoid 22 of the relay 18 and the switching contact 16 of the motor current circuit 10 is closed against the force of a spring, not shown. As a result, the DC motor 12 is started. If a predetermined nominal power of the DC motor 12 , to which the series resistor 14 is tuned, is exceeded, the series resistor 14 is heated until the temperature fuse 28 is triggered. In this case, the switching element 30 interrupts the control circuit 24 . As a result, the relay 18 drops off, so that the motor circuit 10 is opened via the switching contact 16 . Since only a relatively small control current flows through the temperature fuse, a small design and reliable operation are guaranteed.
