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 the direct-type washing machine of the present invention, Figure 3 is a functional diagram of the direct-attached washing machine of the present invention, the washing outer tank (1) containing the wash 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 having a threaded portion 41 for transmitting the rotational force of the motor 5 through the central portion of the hub 3; A washing rod 6 coupled to the upper side of the drive shaft 4 and rotating together with the motor 5; By controlling the rotational force of the motor (5) transmitted to the laundry rod (6) is composed of a power interruption mechanism (7) for transmitting the rotational force to the hub (3) and the washing inner tank (2) and the washing blade (21).

The power control mechanism 7 is provided with a drive portion 7a and a driven portion 7b on the upper and lower portions of the drive shaft 4, and a drive tooth portion 71a is formed on the upper surface of the drive portion 7a. A projection 72a corresponding to the threaded portion 41 of the drive shaft 4 is formed on the lower inner surface of the drive portion 7a, and a driven tooth portion corresponding to the drive tooth portion 71a on the bottom surface of the driven portion 7b. 71b is formed.

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. When it rotates, the laundry rod 6, which receives the rotational force from the drive shaft 4, rotates to generate a rotational water stream to wash the laundry.

That is, when the motor 5 rotates forward, the drive shaft 4 rotates to rotate the laundry rod 6, and the screw portion 41 is rotated by the rotation of the screw portion 41 formed at the lower portion of the drive shaft 4. ) And the projection 72a, which is correspondingly fastened, rises under the guidance of the screw portion 41, so that the driving portion 7a of the power control mechanism 7 rises, but the driving teeth 71a and the blood of the driving portion 7a are raised. Since the motor 5 reversely rotates before the driven tooth portion 71b of the eastern portion 7b contacts, the projection 72a is lowered again while being guided by the screw portion 41 formed on the drive shaft 4. As a result, the driving tooth portion 71a and the driven tooth portion 71b come into contact with each other to prevent the rotational force of the motor 5 from being transmitted.
