態の図である。FIG. 2 shows that a small amount of clothing 40 is washed or
It is the figure which showed the state which is performing rinsing. At the time of washing or rinsing, the reversal time is long, so that the stirring blade 6 rotates clockwise or left for a long time, so that the clothes 40 in the washing tub 5 are centrifugally generated by the rotation of the stirring blade. The clothes are circulated in the washing tub 5 while the clothes are being brought to the inner peripheral wall of the washing tub 5. In addition, the washing water 42 is one in which a vortex is generated by a water flow generated by the rotational force of the stirring blade. In this state, the stirring blade 6 is stopped, and when the drainage-dehydration process is started, the vortex generated by the stirring blade 6 and the rotating centrifugal force of the stirring blade 6 cause
A small amount of clothing is biased to the washing tub and the inner wall, and when dewatering is performed in this state, vibrations increase and poor dehydration activation occurs. FIG. 3 is a view showing a state in which the stirring blade 6 is inverted for a few seconds or several minutes before the end of the washing or the rinsing for a period shorter than the inversion time at the time of the washing or rinsing shown in FIG. .
第３図における撹拌翼６の反転時限は、第２図に示

てはまだ不充分である。Since the reversal time of the stirring blade 6 in FIG. 3 is shorter than the reversal time of washing and rinsing shown in FIG. 2, the clothes 40 are located substantially in the center of the washing tub 5 and the vortex of the washing water 42 is Second
It is smaller than the vortex at the time of washing or rinsing in the figure.
The clothes 40 are shifted to the inner wall of the washing tub 5 and come to the center of the washing tub 5. However, if the reversal time is the same for both clockwise rotation and counterclockwise rotation, and the rotation is stopped by clockwise or counterclockwise rotation, the clothing 40 is not located at the center of the washing tub after stopping by the inertial rotation and vortex of the clothing 40. A situation arises. In this case, the vortex due to the inversion time during washing and rinsing, the inertial rotation of the garment is less, and the skew state of the garment is less, but when a fully automatic washing machine is used, it is not yet possible to completely dehydrate to the end. Insufficient.
第４図は、第３図で説明した衣類40の片寄りを完全に
無くした状態の説明図であり、撹拌翼６が右回転又は、
左回転で停止する場合において、右回転で停止した場
合、撹拌翼６を左回転方向に、右回転で終了した時限よ
りも短い時限で撹拌翼６を撹拌する。FIG. 4 is an explanatory view of a state in which the bias of the clothing 40 described in FIG. 3 is completely eliminated, and the stirring blade 6 rotates clockwise or
In the case of stopping by the left rotation, when stopping by the right rotation, the stirring blade 6 is stirred in the left rotation direction in a time period shorter than the time period ended by the right rotation.
または、逆に、左回転で停止した場合、撹拌翼を右回
転方向に、左回転で運転した時限よりも短い時限で撹拌
翼６を回転させ、衣類40と渦の流れに制動をかけ、停止
後衣類40が洗濯槽内周にいかず、洗濯槽の中央部に位置
させるようにしたものである。Or, conversely, when stopped with left rotation, the stirring blade 6 is rotated in the clockwise direction in a shorter time period than the time period in which the stirring blade is operated with left rotation, and the clothing 40 and the flow of the vortex are braked and stopped. The rear garment 40 does not go to the inner periphery of the washing tub, but is located at the center of the washing tub.
また、撹拌翼６の回転数を、洗濯又はすすぎ終了前に

回転数よりも低い回転数ですなわちモータ通電時間を短
くして撹拌することにより衣類40の動きや渦を小さく
し、停止後における衣類40の慣性回動を少なくし、布の
片寄りを防止するものである。Further, by stirring the rotation speed of the stirring blade 6 at a rotation speed lower than the rotation speed of the stirring blade 6 during washing or rinsing for several seconds or several minutes before the end of washing or rinsing, that is, by shortening the motor energizing time, The motion and vortex of the garment 40 are reduced, the inertial rotation of the garment 40 after stopping is reduced, and the cloth is prevented from being shifted.

のである。As a method for preventing the clothes 40 from being shifted several seconds or minutes before the end of the washing and rinsing, stirring is performed in a time period shorter than the reversal time during the washing and rinsing, and the vortex during the stirring and the inertial rotation of the clothes 40 are prevented. This is effective in preventing the clothes 40 from being shifted. Although the above-described control method is effective as this method, in addition to the above-described control method, a method of preventing the vortex by the stirring blade 6 and the inertial rotation of the garment 40 is used, and the reversal time of the stirring blade 6 is further shortened. To rotate the garment several times to eliminate the vortex and the inertial rotation of the garment, and to position the garment in the center of the washing tub.

The operation for correcting the offset between the front part and the rear part will be described in more detail. The operation at the front part mainly involves loosening a hardened laundry cloth in a washing or rinsing operation. Then, the loosened laundry is agitated for a shorter time in the forward / reverse rotation period at the rear, so that the laundry that is unevenly distributed on the inner peripheral wall side of the washing and dewatering tub is moved to the center of the washing and dewatering tub to eliminate the deviation. I have to.

起動不良を防止するものである。FIG. 5 is a detailed explanatory diagram of the operation control method of the stirring blade 6. This figure shows the operation time of the right and left rotations of the stirring blade 6 during washing and the stopped state of the stirring blade 6 during reversal. During washing, to provide a strong mechanical force in the garment 40, a long operating time t 1, also the stop time t 2 is reversed in a short period. In general, the relationship between t 1 and t 2 is t 1 > t 2
It has become. When the washing process is completed and the cloth slippage prevention process is started, the time period of t 2 for rotating the stirring blade 6 is shorter than the time period of t 1 for rotating the stirring blade 6 during washing, That is, for a time period of t 3 <t 1 , stirring for several seconds or several minutes,
This prevents the clothes 40 from being shifted. However, t 3 > t 1
When even in a timed stopping time of t 4 when inverted stirring timed has been completed, by the rotation of the stirring blade 6, especially when small amounts load, clothing 40
Are rotated by inertia, the ratio of the clothes 40 located at the center of the washing tub 5 is reduced, and large vibrations are generated at the time of dehydration, so that dehydration start failure occurs. Therefore, during the final stirring of the fabric offset preventing stroke example, when the right rotation direction is stopped, the stirring blade 6 in the left rotation direction rotates at a shorter time interval t 5 than t 3, the vortex during stirring, clothing 40 By controlling the inertia rotation of the clothes 40, the clothes 40 are positioned at the center of the washing tub and are advanced to the drainage-dehydration process, thereby minimizing the vibration during dehydration and preventing the dehydration start failure. is there.

せることを特徴とする全自動洗濯機にある。As described above, the present invention provides a washing and dewatering tub, a stirring blade that is provided at the inner bottom of the washing and dewatering tub and that rotates forward and backward in a short period of time, and rotationally drives the washing and dewatering tub and the stirring blade. A motor for automatically executing a washing step, a rinsing step, and a dehydrating step, and immediately before the washing step or the rinsing step is completed and a transition to the dehydrating step is performed, the stirring blade is rotated in a forward or reverse direction in the washing step or the rinsing step. In a fully automatic washing machine that performs a shift correction operation of a laundry that operates a stirring blade in a forward / reverse rotation period shorter than a time period, the shift correction operation is divided into a front portion and a rear portion, and the rear portion has a forward / reverse rotation shorter than the front portion. A fully automatic washing machine characterized in that a stirring blade is operated for a limited time.

The offset is further eliminated because the offset is made closer to the center of the dewatering tub.
