Method and apparatus for controlling operation of range top heating elements for cooking

摘要

A range has burner elements which are connected in series with a temperature switch. Upon reaching a predetermined temperatures, the switch opens and power to the burner element is secured. The burner elements are preferably open coil units, but radiant burner elements may employ similar technology with a lower upper threshold than prior art units have used. Lowering the temperature in a cooking utensil below common ignition temperatures while still allowing boiling is an objective of many embodiments.

主权项

1. An electric range comprising:
a first exposed coil electric heating element at an upper surface of the range; a temperature sensing switch connected within a drip pan cavity, said connection independent of the first exposed coil electric heating element to electric range in and electrical series with the first exposed coil electric heating element, wherein upon reaching a predetermined upper temperature, the switch opens thereby preventing the flow of electricity to the first exposed coil electric heating element and when the temperature is below a predetermined lower temperature, the switch closes permitting the flow of electricity.
