After detecting that the water is gone [Step (a)], wait for 1 minute before moving to the next process as a temporary standby for draining water, and after 1 minute, [Step (b)], The motor is energized to perform low-speed dehydration for 1 minute [step (c)], and then high-speed dehydration for 1 minute [step (d)].

洗濯水が洗濯兼脱水槽と水受け槽との間の隙間に排水さ
れる。In the dewatering operation in the rinsing step immediately after the washing step, the laundry containing the washing water having a large amount of detergent is dewatered, and the washing water having a large amount of detergent is also used for washing. It is drained into the gap between the dehydration tank and the water receiving tank.

濯兼脱水槽と水受け槽との間の隙間が狭くなっている。
このため、脱水運転を行うと、洗剤分の濃い洗濯水がこ
の狭い隙間に一気に排水されることになり、排水ホース
での排水能力が追いつかない。By the way, in recent years, there has been a tendency to make the washing / dehydrating tub large in order to increase the capacity of the laundry, and the gap between the washing / dehydrating tub and the water receiving tub is narrowed.
For this reason, when the dehydration operation is performed, the washing water with a strong detergent content is drained all at once into this narrow gap, and the drainage hose cannot keep up with the drainage capacity.

0分程度を要し、運転に支障を来す。In this state, the washing / dehydrating tub and the rotary blades rotate for dewatering, so that the washing liquid having a large amount of detergent is stirred in a narrow gap to generate bubbles, and the bubbles rotate with the washing / dehydrating tub. It becomes a resistance to the motor that rotates the blades and heats the motor. Since the bubbles are light and are not discharged in a short time, if the operation is continued in this state, the safety device of the motor is activated and the motor is stopped, and then, for example, 3 is taken by the time of recovery.
It will take about 0 minutes and will interfere with driving.

る。The object of the present invention is to eliminate the disadvantages of the conventional example, and during the dehydration operation in the first rinse step, the wash water is drained into the gap between the washing / dehydrating tank and the water receiving tank. An object of the present invention is to provide an operation control method for a washing machine, which can prevent the operation from being stopped due to the heating of the motor when the foaming occurs due to the agitation of the washing water and the operation is stopped halfway.

脱水では泡が発生する可能性が低くなる。According to the first aspect of the present invention, the washing water discharged from the laundry during the spin-drying operation cannot be completely drained, and is collected in the gap between the washing / dehydrating tank and the water receiving tank, and the washing water is stirred. As a result, bubbles are generated, and the bubbles become a resistance, and after a lapse of a predetermined time after the start of dehydration, if it is detected that the number of rotations of the motor has not reached a predetermined value, the dehydration operation is stopped, and the motor is stopped. It is possible to prevent heating. After the dehydration is stopped, water is supplied and a rinse operation is performed to dilute the detergent component, so that the possibility that bubbles will be generated in the next dehydration is reduced.

When bubbles are generated and the bubbles become a resistance and the number of rotations of the motor that rotates the washing / dewatering tub and the rotor after the dehydration operation starts increases and then decreases, the dehydration operation is stopped and the motor is stopped. It is possible to prevent heating. After the dehydration is stopped, water is supplied and a rinse operation is performed to dilute the detergent component, so that the possibility that bubbles will be generated in the next dehydration is reduced.

As a result, bubbles are generated and the bubbles become a resistance, and when it is detected that the number of rotations of the motor has not reached the prescribed value after the elapse of a predetermined time after the start of dehydration, or after the start of dehydration operation, washing and removal are performed. When the number of rotations of the motor for rotating the water tank and the rotary blade rises and then decreases, the dehydration operation is stopped, so that the motor can be prevented from heating. And after the dehydration is stopped, water is supplied and a rinse operation is performed to dilute the detergent component,
The next dehydration will reduce the possibility of foam formation. Furthermore, by setting the drainage time after this rinsing longer than the previous drainage time, sufficient draining is performed, and the possibility that bubbles will be generated in the next dehydration is further reduced.

And after the dehydration is stopped, water is supplied and a rinse operation is performed to dilute the detergent component,
The next dehydration will reduce the possibility of foam formation. Further, in this water supply rinsing operation, since the amount of water is larger than that of the last time, the detergent component has a larger diluting effect, and the possibility of generating bubbles in the next dehydration is further suppressed.

It comprises a first rinsing step, a second rinsing step, and a dehydration step. The present invention relates to a dewatering operation method in a first rinsing step following a washing step, and other draining steps in other washing steps, second rinsing step, dewatering step, and first rinsing step. Since the steps, the temporary standby step after drainage, the dehydration stop step, and the water supply step are the same as those in the conventional method, detailed description thereof will be omitted here.

プ(ヤ)〕。By the way, the step (L) (W)
In (wa), if the rotation speed of the motor 7 has not reached 75 rpm at the time when 10 seconds have passed after the start of the low speed dewatering operation, the water is discharged into the gap 4 between the washing / dehydrating tank 3 and the water receiving tank 1. The washed water is agitated and bubbles are generated there, and it is determined that the bubbles act as a resistance to prevent an increase in the number of rotations of the motor 7, and the actuators 10 and 11 are energized to operate the brake. Thus, the washing / dehydrating tub 3 is forcibly stopped, the drain valve 9 is closed, and the dehydration operation is stopped [step (YA)].

This bubble becomes a resistance, and after a lapse of a predetermined time after the start of dehydration, if it is detected that the rotation speed of the motor has not reached a predetermined value,
Or, if the number of rotations of the motor that rotates the washing / dehydrating tub and the rotor after the dehydration operation starts increases and then decreases,
Since the dehydration operation is stopped, heating of the motor can be prevented. After the dehydration is stopped, water is supplied and a rinse operation is performed to dilute the detergent component, so that the possibility that bubbles will be generated in the next dehydration is reduced.
