摘要： PROBLEM TO BE SOLVED: To provide a washing machine capable of performing control with high accuracy by calculation with a small processing load without detecting a phase current of a motor.SOLUTION: A current detecting resistance is inserted between a lower side switching element configuring an inverter circuit and a ground, and a control circuit reads a peak value of a terminal voltage of the current detecting resistance via a peak hold circuit. Then, when outputting a PWM signal generated based on voltage phase control to each switching element configuring the inverter circuit, the control circuit performs A/D conversion of the peak value acquired by the peak hold circuit and compares it with a reference value, and when the peak value surpasses the reference value, it gradually reduces duty of the PWM signal according to the size of the surpassing difference.

摘要： PROBLEM TO BE SOLVED: To efficiently and surely eliminate an unbalanced state in a rotating drum.
SOLUTION: In this drum type washing machine, an unbalanced state in the rotating drum is recognized based from the rotation variation of a motor in a process wherein the revolution number of the motor is raised to a maximum revolution number at the time of a dehydrating operation, and a cloth loosening control in response to the unbalanced state is performed. For example, when it is judged that an unbalance occurs in the right and left sections in the rotating drum, the driving of the motor is stopped for one time, and then, the motor is rotated for 5 seconds at a low speed so that the revolution number of the rotating drum may become approximate 50 rpm. When it is judged that an unbalance occurs at around the center of the rotating drum, the driving of the motor is stopped for one time, and then, the motor is rotated for 20 seconds at the low speed so that the revolution number of the rotating drum may become approximate 50 rpm.
