ABSTRACT:
A top cover locking system and a method for a boiling clothes washing machine includes a microcomputer for controlling the operation of the system. A heater boils the washing water along with clothes to be washed. A top cover locking system is provided with a switch for detecting the opening/closing of the top cover. The detected signal is applied to the microcomputer, and a solenoid valve locks or releases the top cover according to the control signal from the microcomputer during the boiling wash and dehydrating modes, thereby preventing accidents and promoting thermal efficiency.
