<P>PROBLEM TO BE SOLVED: To detect a motor rotating state and a motor coil leakage just after starting, with simple constitution. <P>SOLUTION: A motor 13 rotatably drives a rotary tube, and is vectorially controlled by a motor driving control means composed of a microcomputer 33. The microcomputer 33 functions as a control means for controlling washing operation. A voltage dividing resistance 53 is arranged between the motor 13 and GND 2. The microcomputer 33 also functions as a rotating state detecting means and a leakage detecting means, and detects the rotating state of the motor 13 on the basis of voltage generated in the voltage dividing resistance 43 just after starting the motor, and detects the leakage generated in a motor 13 part on the basis of the voltage generated in the voltage dividing resistance 53 at undriven time of the motor 13. <P>COPYRIGHT: (C)2004,JPO |
