The invention relates to a washing
machine and a
water treatment system using the washing
machine. The washing
machine comprises an external drum, an internal drum arranged in the external drum, and a
thumb wheel arranged in the internal drum, wherein the
thumb wheel is driven by a main motor, and an output shaft of the main motor is connected with the external drum and the internal drum through an electronic
clutch; the internal drum comprises at least two pairs of elastic valve bodies and non-elastic valve bodies which are connected together in turn to form a drum body, and through holes which are only opened when the washing machine performs a
dewatering process are distributed on wall bodies of the non-elastic valve bodies; each non-elastic valve body is distributed along the outer edge of the
thumb wheel and is connected with a connecting rod which is used for controlling the
radial displacement of the non-elastic body, and the connecting rod is connected with a driving mechanism; when the washing machine performs a washing process and a rinsing process, along with the rotation of the thumb wheel, the driving mechanism controls each non-elastic valve body to perform quick radial reciprocating displacement through the connecting rod; and when the washing machine performs the
dewatering process, along with the rotations of the external drum and the internal drum, the driving mechanism controls each non-elastic valve body to extrude towards the center of the thumb wheel through the connecting rod and releases each non-elastic valve body until the
dewatering process is finished. The washing machine can knead and rub clothes in the washing and rinsing processes and can perform dewatering with extruding force in the high-speed rotary dewatering process.
