Abstract

Es wird eine Temperaturmeßeinrichtung für eine Regelschaltung(10) insbesondere eines elektrischen Strahlungsheizgeräts mit einem unterhalb eines Glaskeramik-Kochfeldes(1) angeordneten Heizleiter(2) vorgeschlagen, bei der für die Temperaturerfassung der Heizleiter(2) selbst genügt. Es ist ein Umschalter(6) vorgesehen, der den Heizleiter(2) zyklisch an eine Widerstandsmeßschaltung(7) legt. Diese erfaßt den jeweiligen temperaturabhängigen ohmschen Widerstandswert des Heizleiters(2) und erzeugt ein temperaturproportionales Steuersignal für die Regelschaltung(10).

Figure 00000001
A temperature measuring device for a control circuit (10), in particular an electric radiant heater with a heating conductor (2) arranged below a glass ceramic cooktop (1), is proposed, in which the heating conductor (2) itself is sufficient for temperature detection. A changeover switch (6) is provided, which connects the heating conductor (2) cyclically to a resistance measuring circuit (7). This detects the respective temperature-dependent ohmic resistance value of the heating conductor (2) and generates a temperature-proportional control signal for the control circuit (10).
