The lower portion of the water tank 11 is equipped with a drive motor 14 for generating power, and the drive motor 14 receives the power from the dehydration shaft to selectively drive the washing tank 12 or the pulsator 16 by receiving power ( A power train 15 having 24 and a washing shaft 23 is provided. A drain pipe 19 is connected to the lower part of the water tank 11 for guiding water drained after washing or dehydration to the outside during washing, and a drain motor 20 for opening and closing the drain pipe 19 is installed. . On the other hand, the upper side of the main body 10 is provided with a water pipe 21 for guiding the wash water supplied from the outside to the water tank 11 inside the main body 10, and communicates with the water pipe 21 to wash the inside of the washing tank 12. A water supply device 22 for supplying water is provided above the main body 10. And the pulsator 16 is composed of the upper blade 17 and the lower blade 18, the upper blade 17 to drive the rotary drive in the washing tank 12 to perform the washing function, the lower wing 18 The part of the washing water is forced to raise the washing water through the rising induction pipe 25 provided on the inner wall of the washing tank 12 to fall into the washing tank 12 from the upper washing tank 12.

In the conventional washing machine configured as described above, when external commercial power is applied, external water is supplied into the water tank 11 by opening the water supply device 22. Then, after the appropriate amount of water is supplied to the water tank 11, the drive motor 14 is operated so that the power transmission device 15 causes the washing tank 12 or the pulsator 16 to be driven by the power transmitted from the drive motor 14. To transmit power. First, when washing, the pulsator 16 is rotated forward and backward, thus, the water flow generated by the upper wing 17 of the pulsator 16 and the falling water generated by the lower wing 18 in the washing tank 12 and Washing is performed by the friction force of the pulsator 16. When the washing is completed for a predetermined time, the drain motor is opened to discharge water to the outside through the drain pipe 19, and then the rinsing stroke is continuously performed.
