Abstract
An overheating prevention apparatus of a boiling water washing machine including a heater for boiling clothes with hot water. The apparatus includes a first thermistor for sensing the temperature of the heater; a heater temperature sensing section for generating a first temperature sensing signal corresponding to the temperature of the heater; a second thermistor for sensing the temperature of washing water supplied to a tub; a water temperature sensing section for generating a second sensing signal corresponding to the temperature of the washing water; a first temperature comparing section for comparing the first temperature sensing signal with a reference signal considered as an overheating temperature signal; a second temperature comparing section for comparing the second temperature sensing value with the sum of the first temperature sensing value and a predetermined value; a temperature increment calculating section for calculating temperature increments for a predetermined time period by the first temperature sensing signal, and comparing the calculated value with a predetermined reference value a load drive section and a power supply switching section including at least two relay means for operating the heater.
