Device for controlling or limiting temperature in an electric cooking appliance.

摘要

A device for controlling or limiting temperature in an electric cooking appliance comprises a switch (44) and a temperature sensor (42) operatively coupled to the switch. The temperature sensor comprises a rod (46) arranged substantially coaxially within a tube (52), the rod being made of a material having a first coefficient of thermal expansion and the tube comprising at least two tube portions (48, 50), one of the tube portions being made from a material having a second coefficient of thermal expansion lower than the first coefficient of thermal expansion and another of the tube portions being made from a ceramic material having a third coefficient of thermal expansion intermediate the first and second coefficients of thermal expansion. The device can be incorporated into a cooking appliance which includes at least two heating elements (22, 24) defining separate heating areas for the cooking appliance. <IMAGE>
