In addition, when the stirring device 14 is rotated forward and reverse during the washing process, the water storage tank 12 is vibrated by the rotation of the washing tank 13 and water, and the water storage tank 12 is the main body 11 through the hook rod 17. Vibration is alleviated by resilient hanging inside.

After the washing cycle is completed, the washing water is first drained, and then a rinsing cycle is performed. During the rinsing cycle, a normal water supply stroke proceeds and at the same time a predetermined amount of water is stored in the water tank 12, the foreign body removal device 20 is removed by the microcomputer. Pump means 21 is operated, and the water stored in the water tank 12 is pumped to the filter cylinder 23a of the filter means 23 installed at the upper end along the pump hoses 22 and 22 '. The water pumped into the filter barrel 23a is filtered by the filter member 23d therein, and is then sprayed into the washing tank 13 through the discharge hole 23c to remove the detergent liquid remaining in the laundry. Washed clean, the contaminated water is discharged to the water tank 12 through the through hole (13a) of the washing tank (13).

When a predetermined amount of water is stored in the water tank 12, the pump means 21 of the water supply and the foreign matter removing device 20 is stopped and the motor 15 is rotated forward and backward, and the rotational force thereof is the power switching means 16. At the same time it is transmitted to the deceleration in the power switching means 16, the forward and reverse power is transmitted to the stirring device 14 through the washing shaft (16a), at which time the washing water is rotated and the laundry is rotated forward and reverse the laundry The water is rinsed cleanly, and after a predetermined time elapses, the contaminated water is drained out through the drainage means. In the rinsing cycle, the above process is repeated several times, so that the laundry detergent is completely removed.

After the rinsing cycle is repeatedly completed, the dehydration stroke proceeds. When the motor 15 rotates in one direction at a high speed in the dehydration process, the washing shaft 16a and the dehydration shaft 16b rotate together by the power switching means 16 at a high speed. At this time, the washing tub 13 is rotated at a high speed. When the washing tank 13 is rotated at a high speed, centrifugal force is applied to the laundry to spread the laundry toward the inner circumferential surface of the washing tank 13, and the washing water contained in the laundry is dehydrated. In addition, the dewatered wash water is discharged toward the water storage tank 12 along a plurality of through holes 13a formed on the inner and outer circumferential surfaces of the washing tank 13, and the washed water is discharged to the outside through the drainage means.
