みを実行する。In FIG. 5, the laundry is put into the washing / dehydrating tub 15 (step 101), and the detergent is put into a detergent feeding port (not shown) so that the washing / dehydrating tub 15 and the outer tub 14 are separated from each other. Start operation after dropping (steps 102, 103)
Then, the water supply valve 37 is operated to start the water supply (step 106), and at the same time, the washing / dehydrating tank 15 is operated by the A
The rotation starts in the direction (step 107). At this time, as shown in FIG. 6, the washing water rotates the bottom of the outer tub 14 in the direction A, but since the guide wall 29 is provided in the opening 28, the washing water does not flow into the opening 28. It is configured. When water is supplied while rotating the washing / dehydrating tub 15 in this manner, the introduced detergent is dissolved by the stirring force generated by the rotation of the washing / dehydrating tub 15. After that, when the water level reaches C (step 108), the washing and dehydrating tub 1
5 stops the rotation (steps 110 and 111) and executes only water supply.

03) Let me. After that, the motor 18 is turned on to rotate the washing / dehydrating tub 15 in the direction A (step 204) for centrifugal dehydration, and the detergent component contained in the clothes is blown out together with the water. After dehydration for a predetermined time (T = T3) (step 205), the motor 18 is turned off (step 20).
6) Then, the deceleration mechanism / clutch 20 brakes the rotation of the washing / dehydrating tub 15 (step 207) to stop the rotation.
After that, the clutch is switched (step 208), the operation of the drain valve 38 is stopped (step 209), and the water supply valve 37 is operated to start the water supply (step 210). When the water level reaches D (step 211), the braking of the deceleration mechanism / clutch 20 is released to switch the clutch (steps 212 and 213), and at the same time, the motor 18 is turned on to turn on the washing / dehydrating tub 15. Rotate in the B direction (step 214). At this time, the washing water is guided by the guide wall 29 in a state where the detergent component is diluted, and the opening 2
8 and rises through a circulation passage 26 formed by the outer tank 14 and the partition wall 25.
The foam is discharged into the washing / dehydrating tub 15 from the foam discharging part 24 of the cover body 22 which communicates with the opening 27 at the upper end of 6, and is circulated. After that, when the water level reaches E (step 215), the power supply to the motor 18 is turned off (step 216), and the rotation of the washing / dehydrating tub 15 is braked by the speed reduction mechanism / clutch 20 (step 217). The clutch is switched (step 218). When water is continuously supplied to the final predetermined water level F (step 219), the water supply is stopped (step 220), the stirring blade 21 is rotated forward and reverse (step 221), and rinsed for a predetermined time (T = T4) (step S221). After performing 222), energization of the motor is terminated (step 223), and the rinsing process is terminated (step 224).

A circulation passage 26 having a lower end opening 28 at the lower end, and a bubble generation mechanism 3 provided near the lower end opening 28 in the circulation passage 26.
2. When the washing / dehydrating tub 15 is rotated in the B direction, washing water is discharged from the upper end opening 27 of the circulation passage 26, and when the washing / dehydrating tub 15 is rotated in the A direction, the circulation passage is provided. Since the washing water is not discharged from the upper end opening 27 of 26, the amount of the washing water discharged from the upper end opening 27 when the washing / dehydrating tub 15 is rotated in the B direction can be increased. The circulation of more bubbles and washing water can improve the washing performance.

Since the guide wall 29 formed to extend substantially vertically from the bottom surface of the is integrally provided, the washing and dehydrating tub 15 can be efficiently rotated in the B direction with a simple configuration without using a separate component. At the time of washing, the washing water flows into the lower end opening 28 of the circulation passage 26, and the washing water is discharged from the upper end opening 27.
When the washing / dehydrating tub 15 is rotated in the A direction, it is possible to realize a configuration in which the washing water is prevented from flowing into the lower end opening 28 of the circulation passage 26 as much as possible and the washing water is not discharged from the upper end opening 27.

Since the washing and dehydrating tub 15 is rotated for a predetermined time in the direction in which the washing water is discharged from the portion 27, by supplying the foam to the rotating laundry at the same time as the washing water, the foam is generated during the passage of the laundry. Break the bubbles,
High-concentration detergent liquid will soak into the laundry, especially
Since the bubbles combine with the oil and the particle dirt attached to the oil and carry away, the cleaning power for the oil dirt and the like can be enhanced. In addition, since the volume of the washing liquid is increased by making the washing liquid into foam, the detergent component can be made to act on the dirt of the laundry with a small amount of washing liquid. Since it is possible to act on the dirt of the laundry on the upper side of which the mechanical force is hard to be transmitted, it is possible to improve the washing performance and reduce the uneven washing.
