導モータ３への配線である。2. Description of the Related Art Conventionally, this type of electric washing machine has had a configuration as shown in FIG. In FIG. 2, a pulsator 1 rotates left and right alternately to agitate the clothes 2 and wash them. 3 is a single-phase induction motor that drives the pulsator 1. Reference numeral 4 denotes a control device comprising a semiconductor element, which controls the single-phase induction motor 3. 5 and 6 are connected by pulleys and a rubber belt 7 to reduce the speed of the single-phase induction motor 3 and transmit it to the pulsator 1. 8 is wiring from the control device 4 to the single-phase induction motor 3.

の回転時間は同じであった。In the above configuration, the rotation time of the pulsator 1 is as shown in Fig. 3, with an alternating cycle of 2 seconds of left rotation, a pause of 0.6 seconds, and 2 seconds of right rotation. The rotation times were the same.

った。Problems to be Solved by the Invention In such a conventional method of operating an electric washing machine, due to the characteristics of the single-phase induction motor 3, the rotational torque in one of the left and right rotation directions is inevitably weak, and the clothes can only be moved in one direction. It will stop rotating. As a result, the washing performance deteriorates in cases where there is a lot of uneven washing and fabric tangles. At this time, single-phase induction motor 3
In order to equalize the left and right rotational torque of single-phase induction motor 3
If this countermeasure is taken with the winding, the current consumption will increase when one side rotates, and the semiconductor element in the control device 4 that controls the single-phase induction motor 3 will become unbalanced for right rotation and counterclockwise rotation. Another problem is that the price of the single-phase induction motor 3 itself increases.
本発明はこのような問題点を解決するもので、左右回転
時の回転トルクの違う安価な単相誘導モータであっても
良好な洗濯性能を得ようとすることを目的とするもので
ある。The present invention is intended to solve these problems, and aims to provide good washing performance even with an inexpensive single-phase induction motor that has different rotational torques during left and right rotation.

である。Means for Solving the Problem In order to solve this problem, the method of operating an electric washing machine of the present invention changes the rotation time of the left and right sides of the induction motor 3, so that the rotation torque in the left and right directions is weaker. The reversal period is controlled so that the rotation time in one direction is always longer than the other.
作用
以上の電気洗濯機の運転方法により、回転トルクが弱く
回転数が低くて布の回シ方が悪い、一方向の回転時間を
、他の一方向より常に長くすることにより、左右の布の
回シ方を同等にすることができる。Due to the operating method of electric washing machines, the rotation torque is weak and the rotation speed is low, making it difficult to turn the cloth.By always making the rotation time in one direction longer than in the other direction, it is possible to The rotation direction can be made the same.

な洗濯性能が得られる。EXAMPLE Hereinafter, an example of the method of operating an electric washing machine of the present invention will be described with reference to FIG. Note that the configuration is the same as that in FIG. 2, so a description thereof will be omitted. In FIG. 1, the control device 4
The control of a single-phase induction motor 3 is shown. In the same figure, the rotation time of pulsator 1 is 2.4 seconds for counterclockwise rotation and 0
．． It is controlled to pause for 6 seconds and then rotate clockwise for 2.0 seconds. At this time, if the single-phase induction motor 3 is a relatively inexpensive motor for clockwise rotation, the rotational torque during counterclockwise rotation is weak, making it difficult to rotate the clothes 2 in the counterclockwise direction, resulting in uneven washing and fabric tangles. However, since the rotation time for left rotation is longer than for right rotation, clothes can be rotated well in both left and right rotations, and good washing performance can be obtained.
