Description
Einrichtung zur Steuerung der Leistungszufuhr bei elektrischen Haushalt-Wärmegeräten Die Erfindung bezieht sich auf eine Einrichtung zur Vorwahl der Leistungszufuhr bei elektrischen Haushalt-Wärmegeräten, insbesondere bei Kochplatten, unter Verwendung eines gegebenenfalls über einen Steuerverstärker mit Temperaturfühler regelbaren Halbleiterstromtores, sowie eines damit verbundenen Stufenschalters, durch den das Stromtor eingeschaltet oder kurzgeschlossen werden kann.Device for controlling the power supply in electrical household heating devices The invention relates to a device for preselecting the power supply in electrical household heating devices, in particular in hotplates, using one that can be regulated via a control amplifier with a temperature sensor Semiconductor current gates, as well as an associated tap changer through which the Power gate can be switched on or short-circuited.
Es ist vorgeschlagen worden, die Leistungszufuhr bei elektrischen Haushalt-Wärmegeräten mit einem Halbleiterstromtor veränderbar zu machen. Ein die Temperatur und damit die Leistung messender Fühler, z. B. ein temperaturabhängiger Widerstand, steuert den Gitterkreis des Stromtores gegebenenfalls über einen Steuerverstärker.It has been suggested that the power supply in electrical To make household heating devices changeable with a semiconductor current gate. One the Temperature and thus the power measuring sensors, e.g. B. a temperature dependent Resistor, controls the grid circuit of the power gate, if necessary via a control amplifier.
Es ist ersichtlich, daß bei Wechselspannungsbetrieb eine derartige Einrichtung eine Regelung der elektrischen Leistungszufuhr etwa im Bereich bis zur halben Nennleistung ermöglicht, weil nur eine Halbwelle des Wechselstromes ausgenutzt wird. Um den Nachteil der nur zur Hälfte ausgenutzten Nennleistung des Heizkörpers zu beseitigen, ist es möglich, zwei Stromtore in Gegenparallelschaltung anzuordnen, wodurch beide Halbwellen ausgesteuert werden können. Die Voraussetzung hierfür ist eine den Aufwand beträchtlich erhöhende Phasenumkehrstufe.It can be seen that with AC voltage operation such Establishing a regulation of the electrical power supply approximately in the range up to half the nominal power, because only a half-wave of the alternating current is used will. About the disadvantage of only half of the nominal output of the radiator to eliminate, it is possible to arrange two power gates in opposite parallel connection, whereby both half waves can be controlled. The prerequisite for this is a phase inversion stage which increases the cost considerably.
Die der Erfindung zugrunde liegende Aufgabe besteht darin, eine Einrichtung zur Vorwahl der Leistungszufuhr anzugeben, die es mit einfachen Mitteln ohne erheblichen Mehraufwand gestattet, die Leistung zwischen Null und dem Nennwert auch bei einteiligen Heizkörpern zu verändern.The object on which the invention is based is to provide a device to indicate the preselection of the power supply, which can be achieved by simple means without significant Additional effort allowed, the performance between zero and the nominal value even with one-piece To change radiators.
Die Aufgabe wird nach der Erfindung dadurch gelöst, daß parallel zum Stromtor ein Gleichrichterelement mit einer dem Stromtor entgegengerichteten Polung angeordnet ist, das durch den Stufenschalter zusätzlich oder an Stelle des Stromtores einschaltbar ist. Mit dieser Maßnahme ergibt sich vorteilhaft die Möglichkeit, die Leistung zwischen dem halben und dem vollen Wert der Nennleistung auszusteuern. Die Regelbarkeit der Leistungszufuhr ist durch die Vorwahl mit dem Stufenschalter um das Doppelte erhöht, ohne daß ein großer Mehraufwand an Betriebsmitteln hierfür erforderlich ist.The object is achieved according to the invention in that parallel to Stromtor a rectifier element with a polarity opposite to the Stromtor is arranged by the step switch in addition to or instead of the power gate can be switched on. With this measure there is advantageously the possibility that To control power between half and the full value of the nominal power. The controllability of the power supply is through the preselection with the step switch doubled without the need for a great deal of additional resources is required.
An Hand der Zeichnung sei ein Ausführungsbeispiel nach der Erfindung beschrieben und die Wirkungsweise erläutert.An exemplary embodiment according to the invention is given with reference to the drawing described and the mode of operation explained.
In der Figur ist ein Heizkörper 1 gezeigt, der über einen Schalter 2 an die Netzanschlußklemmen 3, 4 angeschaltet und damit an Spannung gelegt ist. Der Schalter 2 weist die Schaltstellungen 5, 6, 7, 8 und 9 auf, die eine verschiedenartige Leistungszufuhr ermöglichen. In der Zuleitung 10 ist hinter dem die Schaltstellung 6 bildenden Kontakt ein Halbleiterstromtor 11, z. B. ein steuerbarer Siliziumgleichrichter, angeordnet. Hinter dem die Schaltstellung 8 bildenden Kontakt ist ein Gleichrichterelement 12, z. B. ein Siliziumgleichrichter, angeordnet. Mit dem Schalter 2 können, wie aus der Figur ersichtlich, die nachfolgend beschriebenen Betriebsarten hinsichtlich der Leistungszufuhr vorgewählt werden.In the figure, a radiator 1 is shown, which has a switch 2 is connected to the mains connection terminals 3, 4 and thus connected to voltage. The switch 2 has the switch positions 5, 6, 7, 8 and 9, which are of different types Enable power supply. In the supply line 10 is behind the switch position 6 forming contact a semiconductor current gate 11, z. B. a controllable silicon rectifier, arranged. Behind the contact forming the switching position 8 is a rectifier element 12, e.g. B. a silicon rectifier arranged. With switch 2, how apparent from the figure, the operating modes described below with respect to the power supply can be selected.
In Stellung 6 liegt das Stromtor 11 in Reihe mit dem Heizkörper 1. Gemäß dem am Gitteranschluß 13 eingespeisten Signal, das von der abgegebenen Leistung des Heizkörpers 1 abhängig sein kann, ist die Leistungszufuhr zwischen Null und dem halben Wert der Nennleistung möglich. In Stellung 7 werden die Kontakte der Schaltungen 6 und 8 durch den Schleifer 14 des Schalters 2 überbrückt. Damit ist dem Stromtor 11 das Gleichrichterelement 12 mit einer dem Stromtor 11 entgegengerichteten Polung parallel geschaltet. Der Steuer- bzw. Regelbereich der Leistungszufuhr liegt zwischen dem halben und dem vollen Wert der Nennleistung. In Stellung 8 ergibt sich durch die Reihenschaltung von Gleichrichterelement 12 und Heizkörper 1 ein Festwert der halben Nennleistung infolge der durch Einweggleichrichtung erzielten Leistungshalbierung. In Stellung 9 wird dem Heizkörper durch die Überbrückung 15 die volle Leistung zugeführt. Der Heizkörper 1. wird in der Schaltstellung 5 allpolig vom Netz bzw. den Anschlußklemmen 3, 4 abgeschaltet.In position 6, the power gate 11 is in series with the radiator 1. According to the signal fed in at the grid connection 13, which may be dependent on the output of the radiator 1, the power supply between zero and half the value of the nominal power is possible. In position 7, the contacts of the circuits 6 and 8 are bridged by the wiper 14 of the switch 2. The rectifier element 12 is thus connected in parallel to the current gate 11 with a polarity opposite to the current gate 11. The control or regulation range of the power supply is between half and the full value of the nominal power. In position 8, the series connection of rectifier element 12 and radiator 1 results in a fixed value of half the nominal power as a result of the power halving achieved by half-wave rectification. In position 9, the radiator is supplied with full power through the bridge 15. The heating element 1. is switched off from the mains or the terminals 3, 4 on all poles in the switch position 5.
