This will be explained with the help of a diagram. After the washing process is completed, the process moves to the rinsing process. First, after washing is finished, drain the detergent-containing water remaining in the washing tub. Further, the motor controller 2 causes the condenser-type induction motor M to rotate at high speed in order to scatter the water containing the detergent contained in the clothes by centrifugal force.

到達するまでの時間である。At this time, the motor control device 2 controls the condenser type induction motor M to periodically turn ON and OFF so that the clothes in the washing tub do not become unbalanced. Such a dehydration method is hereinafter referred to as intermittent dehydration. Figure 2 shows how the voltage across the capacitor 1 changes over time after the intermittent dehydration starts. Here, vo in FIG. 2 is the voltage across the capacitor 1 immediately after the start of intermittent dehydration, and T is the voltage across the capacitor 1. ?

る。If V≧v0+va holds true, the timer of the timer device is stopped and the counted time T is classified into three categories depending on the magnitude of the time T. That is, if o<'r<tl, it is assumed that the load amount is small, and the subsequent steps are set to course A and controlled. Similarly, if t1≦T<t2, the load amount is considered to be medium and course B is set, and if t2≦T, course C is set with the load amount being set to dog. Here 11.1
2 is a predetermined value, and the set course is, for example, the course shown in the table. This data is stored in the storage unit 8, and the data in the storage unit 8 is used in the subsequent rinsing process and dehydration process. It is controlled based on the following.

This method can be applied even when the condenser-type induction motor does not cycle through ON/OFF cycles regularly, and during all processes from the start of washing to the end of spin-drying.
