The operation is performed by the solenoid coil 19. Since the water supply system is the same as that of the conventional fully automatic washing machine, the illustration is omitted, and the control for controlling the operation of the drive motor 6, the control of the water supply / drainage system, and the control of the solenoid coil 18 for operating the transmission device 7 is performed. Since the same applies to the device, the illustration is omitted.

It is driven by the drive motor 6 so as to repeat the normal rotation and the reverse rotation at a low speed of 50 rpm in a short cycle. At this time, the rotation direction of the rotary blade 10 is determined by the rotation direction of the drive motor 6, and the transmission 7 reduces the rotation of the drive motor 6 and transmits it only to the inner output shaft 7a to rotate the rotary blade 10 at low speed. Works like that.

The water is discharged from the outlet 14d to the water conduit 15a, rises up the water conduit 15a, flows out of the outlet 15b to the cloth dust collecting filter 16, where the cloth is collected and returned to the washing tub 9. Then, washing water at the bottom of the outer tub 3 is sucked into the pump chamber through the suction ports 9f and 11a together with the cloth waste, and the dewatering / cloth waste discharge hole 9e is provided at the bottom.
The washing water including the cloth waste in the washing tub 9 flows through the washing tub 9.

とができる。In a general washing machine, a relatively large gap is formed between the outer peripheral edge of the rotary blade 10 and the bottom wall 9a of the washing tub 9 in order to avoid contact between them due to manufacturing errors and aging. There is a problem that washing water is spouted by the pumping action due to the rotation of the bottom surface of the rotary wing 10 to diffuse the cloth waste settled on the bottom wall of the washing tub 9. However, in this embodiment, the circulating pump 12 acts to suck the washing water also from the suction port 14b, so that the washing water located at the bottom of the washing tub 9 is provided in the gap on the lower side of the rotary blade 10. As a result, the cloth waste settled at the bottom of the washing tub 9 can be prevented from diffusing, and can be sucked into the pump chamber and sent out to the water conduit 15a.

c serves to suck the washing water from the suction ports 9f and 11a, thereby preventing the washing water circulation flow from being biased.

By opening the drainage electromagnetic valve 17 to drain the washing water in the outer tub 3, the washing water in the washing tub 9 also has holes 9 e, 14 b, 9.
The water is drained out of the tank through f and 11a. The transmission 7 is switched by the solenoid coil 19 to transmit the rotation of the drive motor 6 to the inner and outer output shafts 7a and 7b at a high speed, thereby rotating the washing tub 9 and the rotary blade 10 integrally at a high speed. Thus, the washing water contained in the laundry is centrifugally dehydrated.

And is discharged out of the washing tub and reaches the bottom of the outer tub or settles at the bottom of the washing tub. Circulation pump in the cloth dust collecting means, since the trapping by circulating the fabric scrap collecting portion sucks the wash water from the gap and the outer tub bottom between the rotating blades washing tub, a cloth moving aboard the water flow Dust and sediment at the bottom of the washing tub
The effect is obtained that the collected cloth waste can be efficiently collected.
