Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings using the same reference numerals for the same members, parts.

Figure 2 is a schematic configuration diagram of a direct-type washing machine of the present invention, the washing outer tank (1) containing the washing water; A washing inner tub (2) integrally formed with the washing wing (21) into which the laundry is inserted and installed into the washing outer tub (1); A hub (3) coupled to and fixed to a lower portion of the washing tub (2) to support the washing tub (2); A drive shaft 4 for transmitting the rotational force of the motor 5 to the hub 3; Composed to the upper side of the drive shaft 4 is composed of a laundry rod (6) to rotate with the motor (5).

The lower serration part 42 is formed in the drive shaft 4 to transmit the rotational force of the motor 5 to the hub 3, and the washing rod 6 is formed on the upper side of the drive shaft 4 by the washing rod 6. The upper serration part 41 is formed to transmit the rotational force of.

The laundry rod 6 is fixed by the drive shaft 4 and the vis 7, and the cover 62 having the through hole 63 formed thereon is coupled to the upper side of the laundry rod 6, and the through hole 63. The washing rod 6 of the washing rod 6 is rotated by receiving the rotational force of the motor 5 from the upper serration portion 41 of the drive shaft 4 and flows into the washing water introduced into the hollow portion 64. The nozzle 61 is formed in several places.

Referring to the operation effect according to the above configuration, first, open the door of the washing machine, put the laundry into the interior of the washing tank (2), and then press the operation switch, the appropriate amount of washing water and detergent is supplied to the washing tank (2), When the water level of the wash water reaches the set water level, the supply of the wash water is stopped and at the same time, the motor 5 performs the forward and reverse rotation to wash the laundry. At this time, the motor 5 is reversed. Rotating water flow is generated by the washing blade 21 and the washing tub 2, and the washing rod 6 coupled to the center of the washing tub 2 rotates along with the washing tub 2 to rotate. Generates water flow and jet streams.

That is, the laundry rod 6 is rotated while receiving the forward and reverse rotational power of the motor 5 from the upper serration part 41 of the drive shaft 4 to rotate the water flow in the center of the washing tub 2. Is generated, the washing water flowing into the through hole 63 formed in the cover 62 is stored in the hollow portion 64 is sprayed from the nozzle 61 formed in a plurality of places by the centrifugal force of the rotating laundry rod (6) By the rotation of the motor 5, the jetting flow by the nozzle 61 of the laundry rod 6 is generated along with the rotational flow by the washing blade 21 and the laundry rod 6.

Therefore, in the washing machine as described above, the washing blade 21 rotates by the rotation of the motor 5 and generates the overall rotational flow inside the washing tub 2, and at the same time, the washing is installed in the center of the washing tub 2. The rod 6 rotates to generate more rotational water flow of the washing tub 2, and by washing the sprayed water from the nozzles 61 formed at a plurality of places of the laundry rod 6, washing the conventional motor.
