Heated base unit for a household appliance for heating liquids, comprises a bi-metallic switching strip that operates the heating element in a high and low temperature mode of operation

摘要

The base heating element comprises of a metallic plate (13) that is coated in an insulative material to isolate the appliance form the resistive heating element (21). A sensing means (11) detects the operation temperature and terminates power to the resistive element when a pre-determined temperature is reached. A bi-metallic strip serves to complete the electrical connection and is configured to operate to different temperatures.
