However, if the drum 3 rotates by the repulsive force between the driving unit first magnetic unit 63 and the driving unit second magnetic unit 65, the first magnetic body 633 and the third magnetic body 653 are the same magnetic poles. It is provided to have, and the second magnetic body 635 and the fourth magnetic body 655 will also be provided to have the same magnetic poles.

Hereinafter, for convenience of description, a description will be given based on a case in which the drum 3 rotates due to the attraction force between the driving unit first magnetic unit 63 and the driving unit second magnetic unit 65.

An insulating part 659 may be further provided on the outer circumferential surfaces of the third magnetic body 653 and the fourth magnetic body 655. Although not shown in the drawings, the insulation may be provided on the outer circumferential surfaces of the first magnetic body 633 and the second magnetic body 635, respectively.

Furthermore, when the drum rotation shaft 33 is provided in the drum 3, the second base 651 may further include a second fastening hole 657 to which the drum rotation shaft 33 is fixed.

When the first base 631 rotates by the rotation shaft 611 of the motor 61, the first magnetic body 633 and the second magnetic body 635 rotate, and the first magnetic body 633 and the second magnetic body 635 are rotated. When the third magnetic body 653 and the fourth magnetic body 655 rotates the second base 651 by an attractive force, the drum 3 rotates inside the tub 2.

That is, the drum 3 provided in the laundry treatment apparatus 100 of the present invention is not directly coupled to the rotating shaft 611 of the motor 61 to be rotated, but the driving unit first magnetic unit 63 and the driving unit second magnetic unit. It rotates by the attraction force between 65.

On the other hand, the interval between the drum 3 and the tub 2 during the rotation of the drum 3 will be kept constant by the longitudinal supports 53, 54.

In the clothes treating apparatus 100 having the above-described structure, since the vibration generated when the drum 3 is rotated is not transmitted to the tub 2 through the rotating shaft 615 of the motor, the clothes treating apparatus with reduced vibration and noise. Has the effect of providing.

The inner peripheral surface of the tub and the outer peripheral surface of the drum are maintained at regular intervals through the circumferential support parts 51 and 52 and the longitudinal support parts 53 and 54 as well as the drum 3 rotates. Vibration and noise can be minimized.

Furthermore, the laundry treatment apparatus 100 of the present invention does not need a gasket to prevent the tub 2 from being transmitted to the cabinet because the tub 2 can be separated from the vibrometer.

In the conventional laundry treatment apparatus, a gasket for preventing the insulation of the vibration and the leakage of the washing water inside the tub was essential between the inlet 11 and the tub opening 21. However, the present invention provides vibration insulation in the laundry treatment apparatus 100. There is an effect that can remove the gasket for.

In addition, the laundry treatment apparatus 100 of the present invention can separate the tub 2 from the vibrometer, thereby maximizing the volume of the tub 2 located inside the cabinet 1 having the same volume (maximum washing capacity). You can also expect the effect.

In the conventional clothing processing apparatus, it was necessary to secure a space between the tub and the cabinet to prevent the tub and the cabinet from colliding during the vibration of the tub. The tub can be minimized or separated from the vibrometer, thereby maximizing the volume of the tub 2 located inside the cabinet 1 having a constant volume.
