Next, the operation of the drive unit will be described from the state where laundry and water enter the washing / dehydrating tub 5. When washing general clothes, first, when the second pulley 17b rotates in the Q direction, the clutch spring (1) 128 is in the loosening direction, so that power is not transmitted, and the rotation of the second pulley 17b does not occur. , Is transmitted to the rotary blade 7 through the reduction gear 142 and the honey shaft 143. At this time, the washing / dehydrating tub 5 also tries to rotate due to inertia, but the washing / dehydrating tub 5 is fixed to the washing tub shaft 103 by the female screw 145 through the flange 144 at the bottom.
It becomes the tightening direction of the coil spring 105 and prevents the rotation.

When the second pulley 17b rotates in the R direction, the clutch spring (1) 128 is in the tightening direction, but the plunger 123a of the solenoid 123 and the rising portion 137a of the operating band 137 are engaged with each other, and the spring collar 1

In this way, by fixing the washing / dehydrating tub 5 and reversing the rotary vanes 7, general clothes can be washed by the scrubbing action and the water flow generated by the rotary vanes 7.

On the other hand, when washing a futon or the like, first, the solenoid 123 is energized to attract the plunger 123a, release the engagement of the operation band 137, and release the spring collar 13.
0 is set to the free state. At this time, R the second pulley 17b
By rotating the clutch spring (1) 128 in the tightening direction intermittently,
The rotation is transmitted to the shaft shaft 125 and the washing tub shaft 103 via the boss (2), and the washing / dehydrating tub 5 and the rotary blades 7 are
Rotates intermittently.

At this time, the energizing time to the washing machine motor 15 is ON time of 1.5 seconds and OFF time of 6 seconds,
Since a large amount of water is contained in the washing / dehydrating tub 5, it is very slow during rotation.

As a result, the laundry, together with the washing / dehydrating tub and the rotating blade, moves intermittently in the water in the outer tub, and water containing water or detergent passes through the inside of the laundry to wash it. Dust, sweat and other dirt adhering to the items are removed, and you can wash the laundry without damaging it.

Also, the operation of 1.5 seconds ON-6 seconds OFF is 3
Washing is carried out by repeating the cycle for 4 minutes and then stopping the operation of the motor for 16 minutes 4 times. By providing a 16-minute pause after the motor operation control,

At this time, the clutch spring (2) 129 rotates integrally with the spring collar 130, but since the clutch spring (2) 129 is engaged without tightening margin, it is not wound around the boss (1) 116 and the brake does not operate.

Next, at the time of dehydration, the drain valve 9 is opened to drain water, and then the drive unit 10 is brought into a state similar to that of washing a futon or the like, and the washing / dehydrating tub 5 is rotated at a high speed.

When braking, first the solenoid 123
Of the operating band 137 that is rotating at high speed due to the plunger 123a protruding by stopping the energization of
Lock 137a. At this time, slippage occurs between the operation band 137 and the spring collar 130, and the rotation of the spring collar 130 does not stop immediately. However, due to the sliding resistance of the operating band 137 and the spring collar 130, the clutch spring (2)
129 winds up and the brake operates.
