The spring is transmitted to the rotary wing 7 in the same manner as when the spring is loosened. At this time, the coil spring 105 does not operate because it is in the loosening direction.
The rotational force of the washing and spin-drying tub 5 is transmitted to the boss (2) 124 via a sita shaft 125 integrally connected to the tub 03 and a spring portion 126. At this time clutch spring (2)
Since the bent part 131 of the boss 129 and the spring engaging part 127 of the boss (2) 124 are engaged, the clutch spring (2) 129 winds around the outer periphery of the boss (2) 124 and the boss (1) 116, boss
(1) The rotation is transmitted to the brake plate 114 via the play portion 117 of the 116 to prevent the rotation. In this way, by fixing the washing and dewatering tub 5 and inverting the rotating blades 7, general clothes can be washed by the scrubbing action and the water flow generated by the rotating blades 7.

On the other hand, when washing a futon or the like, the solenoid 123 is first energized to suck the plunger 123a, disengage the operation band 137, and release the spring collar 13
0 is set to a free state. At this time, the second pulley 17b is
Rotating intermittently in the direction
(1) 128 becomes the tightening direction, and the pulley boss 138,
The rotation is transmitted to the sita shaft 125 and the washing tub shaft 103 via the boss (2), and the washing and dewatering tub 5 and the rotary blade 7 rotate intermittently.

At this time, the ON time of the washing machine motor 15 is 1.5 seconds, the OFF time is 6 seconds, and the washing and spin-drying tub 5 contains a large amount of water. It is very slow when rotating.

As a result, the laundry moves intermittently in the water in the outer tub together with the washing / dewatering tub and the rotating blades, and water containing detergent or the like passes through the inside of the laundry, and Dirt such as dust and sweat attached to the object is removed, and the laundry can be washed without damaging the laundry.

The operation of 1.5 seconds ON-6 seconds OFF is 3
After that, washing is performed by repeating a cycle of stopping the operation of the motor four times for 16 minutes. By providing a 16-minute pause after the operation control of the motor, the temperature rise of the motor caused by rotating the washing tub in a full state can be reduced, and at the same time, the washing power can be improved by the washing effect. Things.

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

Next, at the time of dehydration, after the drain valve 9 is opened and water is drained, the driving device 10 is set in the same state as when washing a futon or the like, and the washing and dewatering tub 5 is rotated at a high speed.

At the time of braking operation, first, the solenoid 123
Is stopped, the plunger 123a protrudes, and the rising portion 13 of the operation band 137 rotating at a high speed.
Lock 7a. At this time, a slip 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 between the operation band 137 and the spring collar 130, the clutch spring (2)
129 is wound and the brake operates.
