Abstract (en)
A washing machine to re-perform sensing of the weight of laundry when an AC power is unstable is described. A zero-voltage detector detects a zero voltage of the AC power and generates a zero-voltage signal. If a count value counted according to the zero-voltage signal is greater than a maximum value, a microprocessor recognizes that the a voltage variation is generated due to abrupt power failure and if the count value is less than a minimum value, the microprocessor recognizes that a voltage variation is generated due to noise contained in the power. Then the microprocessor re-performs the sensing of the weight of laundry.
