<p>PURPOSE: To detect the rotational vibration state of a washing barrel by a current flowing through a motor by providing a buffer means receiving and inverting a motor driving signal and a motor stopping signal outputted from a microcomputer to output them by a motor means. CONSTITUTION: When a washing machine 10 reaches a dehydrating process, a microcomputer 1 performs a control program by the dehydrating program according to a previously programmed state. A digital value accompanied with a current value obtained by sensing a current flowing through the motor M of a motor driving part executing dehydration by rotating the washing cylinder 30 is inputted to the microcomputer, which detects the unbalanced state of the washing cylinder 30 by controlling to the program state according to it and controls the motor M to output a driving stop signal at the time of detecting the unbalanced state to stop the dehydrating process. Thus, the unbalanced state of the washing barrel is detected more precisely by this method than that by a control switch 40, thereby the vibrating noise of the washing barrel generated by the malfunction of a vibration sensor is prevented.</p> |
