Claim 1
Independent Claim
95 words
Radiant heating element (11) for heating glass ceramic plates in cookers, with at least two zones (16, 16a, 17, 17a) with timed, power-controlled electric heating resistors (13, 13a, 14, 15, 15a) and a thermal cut-out (19, 19a) with a temperature sensor (18, 18a) extending over both zones (16, 16a, 17, 17a), characterized in that a series heating resistor (15, 15a) arranged in the outer zone (17) of the heating element is connected in series with a central heating resistor (13, 13a) and can be disconnected in one switching state of the thermal cut-out (19, 19a).
Claim 2
Dependent Claim
95 words
Radiant heating element (11) for heating glass ceramic plates in cookers, with at least two zones (16, 16a, 17, 17a) with timed, power-controlled electric heating resistors (13, 13a, 14, 15, 15a) and a thermal cut-out (19, 19a) with a temperature sensor (18, 18a) extending over both zones (16, 16a, 17, 17a), characterized in that a series heating resistor (15, 15a) arranged in the outer zone (17) of the heating element is connected in series with a central heating resistor (13, 13a) and can be disconnected in one switching state of the thermal cut-out (19, 19a).
Claim 3
Dependent Claim

Heating element according to claim 3, characterized in that the series heating resistor (15) takes up part of the circumference and/or the radial extension of the outer zone (17).
Claim 6
Dependent Claim
27 words
Heating element according to claim 3, characterized in that the series heating resistor is arranged separately from the further heating resistor (14) of the corresponding zone (17).
Claim 7
Dependent Claim

Heating element according to claim 6, characterized in that the series heating resistor (15a) closely surrounds a central zone (16a) containing the central heating resistor (13a), the series heating resistor (15a) being an outer heating coil turn.
Claim 9
Dependent Claim
39 words
Heating element according to one of the preceding claims, characterized in that the thermal cut-out (19) has two contacts (20, 21) with different response temperatures, whereof that with the lower response temperature is constructed as a changeover contact (21).
Claim 10
Dependent Claim
54 words
Heating element according to claim 8, characterized in that the changeover contact (21) connects in parallel the heating resistors (13, 14) in a central and an outer zone (16, 17) in an initial cooking phase and on switching over connects one of these heating resistors (13) in series with the series-connected heating resistor (15).
Claim 11
Dependent Claim
79 words
Heating element according to claim 8, characterized in that the changeover contact (21) is located in the lead to the associated heating resistor (13), is constructed as a reversing switch and on reaching its response temperature connects the heating resistor (13) associated therewith in parallel with the in each case next heating resistor (14), the switch (20) with the highest response temperature being in series with the common return line (28) of all the heating resistors (13, 14, 15).
