Further, water is supplied into the outer tank 10.

It is transmitted to the stirring blade 14 via the belt 18, the driven pulley 19, the clutch / deceleration unit 20, and the stirring blade 14 rotates to perform “washing”.

パルスを中央処理回路３８に取り込む。After the motor 16 is rotated for a predetermined time at the end of the "washing", the power of the motor 16 is turned off, and the inertial rotation pulse of the stirring blade 14 immediately after the power supply to the motor 16 is stopped is sent to the central processing circuit 38. take in.

【００３９】この場合、洗濯槽６内の布に大きな片寄り
があると、布全体の周方向の動きが悪く、モータ１６の
通電停止直後における撹拌翼１４の慣性回転数は小さく
なって、そのパルス数も少なくなる。In this case, if the cloth in the washing tub 6 has a large deviation, the movement of the entire cloth in the circumferential direction is bad, and the inertial rotation speed of the stirring blade 14 becomes small immediately after the energization of the motor 16 is stopped. The number of pulses is also reduced.

【００４０】反対に、洗濯槽６内における布の片寄りが
小さい場合、布全体は周方向に良く動くので、モータ１
６の通電停止直後における撹拌翼１４の慣性回転数は大
きくなって、そのパルス数も多くなる。On the contrary, when the deviation of the cloth in the washing tub 6 is small, the entire cloth moves well in the circumferential direction.
Immediately after the stop of energization of No. 6, the inertial rotation speed of the stirring blade 14 increases, and the number of pulses thereof also increases.

動量検出のステップに戻る。When the number of pulses is equal to or more than the preset number of pulses, as shown in FIG. 4, the water in the washing tub 6 is discharged to shift to the dehydration step, and conversely, If the number of pulses is less than the set value, the stirring blade 14 is immediately discharged for a short time (that is, to obtain a weak water flow for loosening the laundry 15) without discharging the water in the washing tub 6. , The time period during which the forward rotation and the reverse rotation are shorter than the time of “washing”), the stirring blade 14 is rotated, and the process returns to the step of detecting the inertial rotation amount of the stirring blade again.

【００４２】つまり、設定値以上のパルス入力のあった
場合のみ脱水行程に移行する。That is, only when there is a pulse input equal to or more than the set value, the dehydration process is started.

細かな制御をおこなうことができる。If there is a pulse input above the set value, in other words, if the shift to the dehydration process is permitted,
Since the larger the number of pulses, the smaller the deviation of the cloth piece, when the number of detected pulses is large, the dehydration time is immediately reduced to shorten the dehydration time. On the other hand, when the number of detected pulses is less than a certain specified number, The rotation speed of the washing tub 6 can be slowed down at first and then gradually increased, or the rotating vibration of the washing tub 6 can be minimized by rotating the washing tub 6 intermittently.
By changing the dehydration operation mode in several stages, fine control can be performed.

As shown in FIG. 5, the permanent magnet 32 fixed to the shaft 31 of the motor 16
And a signal obtained by the coil 33 provided around it, is taken out by the lead wire 34, or as shown in FIG. 6, the inertial rotation time T by the detection of the back electromotive force of the motor and the rotation speed immediately after the motor is stopped are The same effect can be obtained by detecting the time t shown.

い。Also, during "washing" and "rinsing", the inertial rotation amount of the stirring blade 14 after the motor is turned off is detected a plurality of times to obtain an average value, and this and the motor at the final stage of "washing" and "rinsing" are determined. It may be possible to determine whether or not to shift to the dehydration process by comparing the amount of inertial rotation of the stirring blade after turning OFF.

It is also possible to determine the quality and water level, and determine whether or not to shift to the dewatering process by comparing this with the amount of rotation of the stirring blade inertia after the motor is turned off at the final stage of “washing” and “rinsing”.

When shifting to "dehydration" from, it is possible to easily detect the deviation of the laundry cloth, and if there is deviation of the cloth, correct it and always move to a stable dehydration operation. A large blurring of the outer tub 10 due to the one-sided displacement, and thus the outer tub 10 and the outer frame 13 which is the outer peripheral member thereof collide with each other to make a jarring collision sound, and the outer tub 10 and the outer frame 13 may be released at an early stage. You can solve the problems that hurt you. Of course, the outer tank 10
The fact that does not hit the outer frame 13 can eliminate the problem that dehydration cannot be started due to the operation of the safety switch during the dehydration operation.
