A circuit arrangement for heating elements in a cooker hob with at least two individual cooking regions (Ha, Hb, H'b, Hz) with a respective input for an electronic control device for the production of variable heating power, comprises control means whereby the individual cooking regions are usable together by being connected together, in particular for elongate cooking vessels. The current paths for the heating elements associated with the individual cooking regions are switchable through a switching element (SK) (Fig. 5) in such a manner that the heating elements of the individual cooking regions are selectably switched in a first switching position of SK to a respective heating power control device (S3, P3; S4, P4, Fig. 5) or in a second switch position together to one of these heating power control devices (S3, R3) while the further heating power control devices (S4, P4) are separated from their associated heating element. The microprocessor (???P) provides duty cycle regulation of the heating elements via relays (K3-K8, Fig. 5). <IMAGE> |
