Abstract:
1. A method for controlling the supply of power to a radiant heater of a cooking hob by use of a control circuit, the control circuit configured to deliver power to the radiant heater via first and second electrical paths, the method comprising: supplying a first level of power to the radiant heater through a closed disconnection switch situated in the first electrical path; sensing a temperature of the cooking hob; upon detecting that the temperature has reached or exceeded a predetermined temperature, terminating the supply of power to the radiant heater through the first electrical path by opening the disconnection switch and for at least a period of time initiating the supply of a second level of power to the radiant heater through the second electrical path, the second level of power being less than the first level of power and sufficiently low to cause the radiant heater to cool.
