Abstract
Disclosed is a method for controlling a heating-washing operation of a washing machine. A microprocessor has many subroutines for providing optimal washing conditions of the washing machine in correspondence to respective temperatures of washing water, through which optimal washing effect is achieved. Washing water is heated until the temperature thereof reaches a set temperature, and the temperature of washing water is measured while heated. The microprocessor performs individual subroutines corresponding to the measured temperature. The subroutines have data about the amount of washing water, rotational velocity of a drum, and a period for changing the rotational direction of the drum. Heating is stopped when the temperature of washing water reaches the set temperature, and the microprocessor performs the washing operation according to the subroutine corresponding to the set temperature. Thus, washing effect is maximized and energy is saved.
