In order to prevent the operation part 91 from being drawn out from the receiving part 87, the connection part 8 is rotatably fixed to the connection body 81 so that the operation part 91 is connected to the receiving part 87 87 from being pulled out from the outflow preventing portion 88.

As shown in FIG. 4, the outflow preventing portion 88 is provided with a through-hole preventing through-hole 881 through which the rotating shaft 67 can pass through the outflow preventing portion 88.

The outflow preventing portion 88 is rotatably supported by the connection body 81 through a lower portion of the outflow preventing portion 88 and a bearing 89 positioned on the upper portion of the connection body 81. In this case, The portion 88 is held in contact with the bearing 89 through the coupling portion 883. [

The coupling portion 883 may be a nut that is coupled to the circumferential surface of the rotation shaft 67 and presses the withdrawal prevention portion 88 in the direction of the bearing 89.

5, when the actuating part 91 moves to the upper end of the receiving part 87, the first stopper 95 stops the movement of the actuating part 91, So that the rotational power is transmitted to the connecting body 81. [

The first stopper 95 may be an oilless bearing supported by the outflow preventing portion 88. The oilless bearing may be provided in a ring shape as means for minimizing the frictional force between a moving object and a fixed object without supplying lubricant to the friction surface.

When the first stopper 95 is provided as a ring-shaped oilless bearing and the rotation shaft 67 is provided so as to pass through the center of the oilless bearing, the first stopper 95 rotates the rotational shaft 67 It is not only a means for transmitting the rotation to the connection body 81 but also a function of a bearing for rotatably supporting the rotation shaft 67 on the connection body 81. [

The second stopper 96 prevents the movement of the actuating part 91 when the actuating part 91 moves to the lower end of the accommodating part 87 so that the rotational power of the rotary shaft 67 is transmitted to the connecting body 81 As shown in FIG. The second stopper 96 may be a ring-shaped oil-less bearing supported by the bending portion 871.

The first stopper 95 and the second stopper 96 may be formed as shown in FIG.

The first stopper 95 shown in FIG. 6 is provided as a spring positioned between the outflow preventing portion 88 and the actuating portion 91, and the second stopper 96 is provided with the bending portion 871 And a spring positioned between the actuating portions 91. [0035]

In this case, the first stopper 95 is provided to provide a force for moving the actuating portion 91 in a direction away from the outflow preventing portion 88, and the second stopper 96 is provided to move the actuating portion 91 in the direction away from the bending portion 871. [0064]

The first and second stoppers 95 and 96 may be provided to prevent the movement of the actuating part 91. In this case, At least one of the first stopper and the second stopper may be omitted when the pull-out preventing portion 88 and the bent portion 871 are provided, respectively.

Hereinafter, an operation process of the clothes processing apparatus 100 having the above-described structure will be described. 5 shows the case where the actuating part 91 is located at the center of the receiving part 87 for the sake of convenience of explanation but the initial position of the actuating part 91 is hereinafter referred to as the second stopper 96 Described based on the contact state.

When a current for forming a magnetic field rotating in the clockwise direction is supplied to the stator 71, the rotor 73 and the rotary shaft 67 will rotate in the clockwise direction.

When the rotary shaft 67 rotates clockwise, the agitating part 6 fixed to the free end of the rotary shaft will rotate clockwise inside the drum 4.

The withdrawal preventing portion 88 is rotatably supported by the connecting body 81 through the bearing 89. Therefore, when the rotation preventing portion 88 is rotated, The drum 4 fixed to the connection body 81 does not rotate.

On the other hand, when the agitating part 6 is rotated in the drum by the rotation of the rotating shaft 67, the actuating part 91 moves in the direction of the first stopper 95 by the conveying part 93. Therefore, when the rotation shaft 67 rotates by a preset number of times (the reference number of times) (when the stirring part rotates by a predetermined number of times), the operation part 91 will come into contact with the first stopper 95.

When the operating part 91 contacts the first stopper 95, the rotating shaft 67 and the connecting body 81 are connected through the operating part 91 and the first stopper 95, 81 rotate together with the rotary shaft 67. Therefore, the drum 4 will rotate in the same direction together with the agitating part 6. [

The number of reference times for rotating only the agitating part 6 may be variously set through the conveying part 93. However, in consideration of improvement of the washing power by the agitating part, It is preferable that the drum 4 is set to be rotated after at least one rotation is completed.

When the stator 71 is supplied with a current for forming a magnetic field rotating in a counterclockwise direction, the rotor and the rotary shaft 67 will rotate in a counterclockwise direction.

In this case, the stirring portion 6 rotates counterclockwise inside the drum by the counterclockwise rotation of the rotating shaft 67, and the drum 4 is rotated by the second stopper 96 And remains in a stopped state.

However, when the rotary shaft 67 rotates up to a preset number of times and the operating portion 91 contacts the second stopper 96, the drum 4 rotates counterclockwise together with the stirring portion 6 Will be.

The structure and function of the driving unit 7, the connecting unit 8, and the power transmitting unit 9 described above are based on a case where a drawer tub is provided which can be drawn out from a cabinet. However, the driving unit, The present invention can be applied to a clothes processing apparatus in which drawers are omitted.

That is, the driving unit 7, the connecting unit 8, and the power transmitting unit 9 may be applied to a garment processing apparatus including a cabinet, a tub fixed within the cabinet, and a drum rotatably installed in the tub .

The present invention may be embodied in various forms without departing from the scope of the invention. Accordingly, it is intended that the present invention cover the modifications and variations of this invention provided they come within the scope of the appended claims and their equivalents.
