Abstract

PURPOSE:To secure a certain cleaning degree always regardless of the load amount and use the output of motor effectively particularly when the load amount is small by enlarging the rotational operation time of motor in one direction with decreasing load amount on the basis of the result from judging the load amount, shortening the current feed stopping time to the motor, and also shortening the washing time. CONSTITUTION:When agitating wings 3 makes five times of operation through repetition of motor 8 operating cycles consisting of regular rotating, stopping, and reverse rotating, the cumulated value (n) of the number of inertia pulses at this time is calculated by a control device 15, and the load amount is judged. This load amount is considered large if n=50 or less, and automatic setting thereafter is made so that the operating angle of the agitating wings 3, i.e. the current feed angle to the motor 3, is 200 deg., the stop time after current feed is 300 msec, and the washing time is 12 min. These factors are thus set according to the load amount, and particularly when the load amount is small, the operating angle is large, stop time is short, and washing time is shortened, so that the washing can be finished in a short time with a strong water stream when the washes are less to enable effective utilization of the output of the motor 8.

After supplying water to a high water level during powerful washing,

According to the present invention, when water is supplied to a high water level and the load is small, for example, the rotation operation time in one direction of the motor is increased, and the subsequent energization off time is set short, so that the rotation time due to inertia is increased. A strong water flow can be obtained by reducing the amount of water, and
By shortening the overall washing time by that much, the output of the motor can be effectively used to generate water flow, allowing efficient operation and ensuring the specified washing power.

When the load is large, the rotation time of the motor in one direction is short, the off time is long, and the overall washing time is set long, so the next rotation is performed after the rotational force due to inertia has almost disappeared. Since the machine starts operating, a predetermined reversing force is obtained and a predetermined cleaning power is obtained.

As mentioned above, the operating angle, stop time, and washing time of the stirring blade (3) are set according to the load amount. Especially when the load amount is small, the operating angle is large, the stop time is short, and the washing time is short. Therefore, when the amount of laundry is small, washing can be completed in a short time with a strong water flow, and the output of the motor (8) can be used effectively.

Then, the washing operation is performed in a mode corresponding to each load amount (Step 1), and when the set time is reached, the washing operation ends (Step 1), and the process moves to the next step.

〔発明の効果〕〔Effect of the invention〕

以上述べたように本発明の撹拌式洗濯機の運転制御方法
は、強力洗いを行う場合に水位を高水位とし、負荷量に
応じてこれが小さくなる程攪拌翼の動作角度を大きく、
通電後の停止時間を短く、かつ全体の洗い時間を短くし
たので特に負荷量の少ない時は強い水流で短時間のうち

できる。
As described above, the method for controlling the operation of an agitating washing machine according to the present invention sets the water level to a high water level when performing powerful washing, and increases the operating angle of the agitating blade as the water level decreases according to the load amount.
The stop time after energization is shortened, and the overall washing time is shortened, so especially when the load is small, washing can be completed in a short time with a strong water flow, and the motor's output can be used to the maximum extent possible.

また、負荷量の大小にかかわらず、高水位で運転し、か
つ前記のごとく負荷量に対応させて攪拌翼の動作角度等

力が確保でき、洗浄力のバラツキや布傷みなどが生じる
ことを防止でき、信頼性を向上できるものである。
In addition, regardless of the load amount, the operation is performed at a high water level, and the operating angle of the stirring blade is set in accordance with the load amount as described above, so the same cleaning power is ensured regardless of the load amount. This can prevent variations in cleaning power and damage to the fabric, and can improve reliability.
