ってしまう欠点がある。By the way, the laundry in the tub is entangled with each other due to the water flow generated by the agitator, and the laundry is entangled with each other depending on its quantity or quality. It is often encouraged to become dango. However, in the case of the above-mentioned conventional structure, the agitator is rotated under a predetermined washing condition regardless of the quantity or quality of the laundry. This causes a decrease in power or a decrease in rinsing ability. In addition, in the case of an automatic washing machine that continuously executes dehydration operation, when the dumpling state of the laundry occurs due to the washing operation or the rinsing operation, the rotating tub becomes unbalanced during the dehydration and the washing ends. Sometimes there is a drawback that it becomes difficult to take out the laundry.

It is an object of the present invention to provide a washing machine having effects such as prevention.

転条件を弱める制御手段を設けたものである。A washing machine of the present invention is provided with a load amount detecting means for detecting a load amount according to the amount or quality of laundry in a tub a plurality of times during a washing operation or a rinsing operation, The control means is provided to weaken the operating condition of the washing operation or the rinsing operation when the variation in the detected value by the load amount detecting means becomes equal to or less than the set value.

ことを防止することができる。The load amount detecting means detects the load amount according to the amount or quality of the laundry during the washing operation or the rinsing operation.
At this time, when the laundry in the tub is entangled with each other in a dangling state, the value detected by the load amount detecting means changes greatly. As a result, the control means changes the operating condition of the washing operation or the rinsing operation in the direction of shortening the driving time, so that the laundry is prevented from progressing to the dumpling state and the washing ability or the rinsing ability is further reduced. Can be prevented.

The operation will be described with reference to FIG. It should be noted that the flowchart of FIG. 3 describes only the operation related to the load amount detection of the operation control circuit 12, and the description related to the control of the laundry operation is omitted. Further, the operation related to the load amount detection of the operation control circuit 12 is executed in the washing operation and the rinsing operation, but since the control contents thereof are substantially the same, only the control contents of the washing operation will be described and the rinsing operation control The description of the contents is omitted.

うにしてずれ量を１６回求めたところで次に示す数式に
基づいてずれ量の総和を演算する。That is, when the washing operation is started by operating the switch input section 15, the operation control circuit 12 executes load amount detection in step S1. That is, the operation control circuit 12 inputs and stores the load amount from the load amount detection means 21 when the stirring body 4 is rotated counterclockwise, for example.
Subsequently, the operation control circuit 12 again inputs the load amount from the load amount detecting means 21 after a lapse of a predetermined time, and obtains a deviation amount (absolute amount) by subtracting the load amount input this time from the load amount input last time. Then, when the deviation amount is obtained 16 times as described above, the operation control circuit 12 calculates the total deviation amount based on the following mathematical formula.

タ５の負荷量は大きく変動している。このため、ずれ量
の総和であるＫの値は比較的大きな値となっている。At this time, at the start of the washing operation,
Since the laundry is in a disjointed state, the load amount of the washing machine motor 5 greatly changes. Therefore, the value of K, which is the sum of the deviation amounts, is a relatively large value.
【００１６】続いて、運転制御回路１２は、一定時間待

して負荷量Ｋ´を前記Ｋを求める計算式により求める。Subsequently, the operation control circuit 12 proceeds from step S2 to step S3 after standing by for a certain period of time, and obtains the load amount K'by the formula for obtaining K.

なるので、Ｋ＞Ｋ´となるのが一般的である。As the washing operation progresses, the laundry in the rotary tub 3 may become entangled due to the water flow of the agitator 4, and may be in a dango state depending on the quantity or quality of the laundry. .. When the laundry is dumped in this manner, the variation in the load applied to the washing machine motor 5 is reduced, so that K> K 'is generally satisfied.

止することができる。Here, the operation control circuit 12 has K> 2K '.
If it becomes, it is judged that the amount of entanglement is extremely large and the operating condition of the washing operation is changed. That is, the operation control circuit 12
The water flow due to the rotation of the stirring body 4 is weakened or the washing time is shortened. Specifically, the drive timing of the washing machine motor 5 which was on for 1.2 seconds and off for 1.0 seconds was set to 1.0
Seconds on, 1.0 seconds off, or 15 minutes wash time changed to 12 minutes. As a result, the water flow by the agitator 4 is weakened and the progress of the laundry into the dumpling state is prevented, so that it is possible to prevent the washing ability from further decreasing.
【００１９】そして、運転制御回路１２はステップＳ6
に進行して、上述のように変更した洗い条件でもって洗
い運転を洗い時間が終了するまで実行する。The operation control circuit 12 then proceeds to step S6.
And the washing operation is executed under the washing conditions changed as described above until the washing time ends.

ことを防止することができる。In short, according to the above configuration, the entanglement amount of the laundry is detected based on the load amount applied to the washing machine motor 5, and when the entanglement amount becomes equal to or more than the set value, the washing operation is started. By changing the conditions to prevent the entanglement of the laundry, unlike the conventional example where the washing operation is continued in the entangled state of the laundry, it is possible to prevent the washing ability from decreasing. it can.

を取り出し難くなるということもない。Further, in the case of the automatic washing machine, since the entanglement of the laundry is prevented as described above, the rotating tub does not become unbalanced during the dehydration operation, and
There is no possibility that the laundry becomes a strong dumpling and it is difficult to take out the laundry from the rotary tub 3.

る。Further, in the case of a washing machine that is originally provided with a load amount detecting device for detecting the amount or quality of laundry, the load amount detecting device should be used to detect the amount of entanglement of the laundry. Therefore, it is possible to suppress an increase in cost.
【００２３】尚、上記実施例では、洗い運転時の作用を
