Abstract
PURPOSE: To enable a rotation of the pulsator axis, also sense a rotation of the dewatering reservoir independent of the sensing of the rotation, enable a highly accurate control when the water is to be removed, resulting in performing a safe operation of the washing machine.
CONSTITUTION: Dewatering reservoir 2 is provided in a washing reservoir 1, the pulsator 4 and the dewatering reservoir 2 are selectively driven to rotate by the same motor 6 via pulsator axis 3 for driving the pulsator 4 located in the dewatering reservoir 2. In such a constructed automatic washing machine, each of the rotary plates 10 and 11 is fixed to the pulsator axis 3 and the dewatering reservoir 2, and each of the rotary plates 10 and 11 is provided with each of exclusive rotary plate sensors 13 and 14 having an opposing coil 15. In each of the sensors 13 and 14, an output corresponding to a variation of magnetic flux generated in the coil 15 due to an opposing arrangement between the rotary plates 10 and 11, and thereby the rotational speed of the washing machine either in case of washing or in case of dewatering is independently sensed.
