Abstract
In a full-automated washer, a cloth amount sensor detects a quantity of an object being washed which is thrown into a washing drum as a value inclusive of information regarding a degree of bulkiness of the object to be washed. A processing circuit included in the full-automated washer is responsive to a detection output signal from the cloth amount sensor to determine a water supply amount, a cleanser feed amount, a stirring time and a rinsing time. The cloth amount sensor is mounted to a stirring motor. Upon an OFF-state of the motor, the detection output signal is generated by measuring a voltage waveform induced by inertial motion which varies in accordance the degree of bulkiness of the object to be washed.
