Werner Otto in Berlin.Werner Otto in Berlin. Bei Heizkissen o. dgl., bei denen die Temperatur dem Bedarf entsprechend regelbar ist, erfolgte die. Temperaturregelung bisher entweder durch Verwendung eines Stufenschalters in Verbindung mit mehreren Heizwiderständen, die einzeln, parallel und in Serie geschaltet werden können, oder durch Verwendung mehrerer wahlweise schaltbarer Thermostaten in Verbindung mit einem einzigen Hekwiderstand. In beiden Fallen erfolgt die Regelung in ganz bestimmten Stufen, so daß Zwisdhentemperaturen nicht erreicht werden können.With heating pads or the like, where the temperature can be regulated as required is, the. Temperature control so far either by using a step switch in connection with several heating resistors, which can be used individually, in parallel and in Can be switched in series, or by using several optionally switchable Thermostats in connection with a single Hek resistor. In both cases it takes place the regulation in very specific stages, so that intermediate temperatures are not reached can be. Die Erfindung hat zum Gegenstande eineThe subject of the invention is a ι5 Vorrichtung, die eine stetige Änderung der Temperatur zwisdhen einem Höchst- und Mindestwert ermöglicht. Zu diesem Zwecke ist parallel zu einem an sich, bekannten im Stromkreis eines Heizwiderstandes liegenden Heizkörper, der unmittelbar einen Thermostaten beeinflußt, ein regelbarer Widerstand geschaltet, durch dessen verschiedenartige Einstellung eine stetige Regelung des durch den Thermostatheizkörper gehenden Stromanteils möglich ist.ι5 device that has a steady change in Temperature between a maximum and minimum value. To this end is parallel to a known heating element in the circuit of a heating resistor, which directly influences a thermostat, switched a controllable resistor, through its various setting, a continuous regulation of the current component going through the thermostatic radiator is possible. Ein Ausführungsbeispiel der neuen Vorrichtung ist in der Abbildung dargestellt. Im Stromkreis des Heizwiderstandes a, der von einem Stecker & aus gespeist wird, liegt ein fhermostatischer Schalter bekannter Art, dessen bimetallische Lamelle c unter dem Einfluß eines Heizkörpers d steht, der mit ihr in Serie geschaltet ist. Parallel zu dem Heizkörper d liegt ein regelbarer Widerstands. In an sich bekannter Weise kann selbstverständlich der Heizkörper d als Heizspirale um die Lamelle c herumgelegt sein. Je mehr Widerstand man bei e einschaltet, um so mehr Strom fließt durch den Heizkörper d, um so schneller kommt dieser auf die Temperatur, bei der 'die Lamelle c durch ihre Formänderung den Schalter öffnet, um so kürzer ist daher die bis zum Ausschalten des Heizwiderstandes vergehende Zeit, um so niedriger wird somit die Temperatur des Heizkissens gehalten, und umgekehrt. Die Temperatur des Heizkissens wird also durch Zuschalten von Widerstand herabgesetzt,: durch Abschalten von Widerstand erhöht.An embodiment of the new device is shown in the figure. In the circuit of the heating resistor a, which is fed by a plug &, there is a thermostatic switch of a known type, the bimetallic lamella c of which is under the influence of a radiator d which is connected in series with it. A controllable resistor is located parallel to the radiator d. In a manner known per se, the radiator d can of course be placed around the lamella c as a heating coil. The more resistance you switch on at e , the more current flows through the heating element d, the faster it reaches the temperature at which the lamella c opens the switch due to its change in shape, and the shorter the time it takes to switch off the Heating resistance -α elapsing time, the lower the temperature of the heating pad is kept, and vice versa. The temperature of the heating pad is reduced by switching on resistance: increased by switching off resistance.
