Abstract
Methods and apparatus for controlling the supply of power to a radiant heater of a cooking hob. According to one implementation a method is provided that includes the use of a control circuit that is configured to deliver power to the radiant heater via first and second electrical paths. One control method includes supplying a first level of power to the radiant heater through a closed disconnection switch situated in the first electrical path while sensing a temperature of the cooking hob. Upon detecting that the temperature has reached or exceeded a predetermined temperature, the control circuit terminates 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.
