Thus, a required dehydration rate can be obtained while securing the strength of the dehydration mechanism. (At this time, it is conceivable that the dehydration time at 60 Hz is the same as the time at 50 Hz. However, rotating 60 Hz having a high rotation speed for a long period of time as well as 50 Hz is necessary for the dehydration life and the dehydration mechanism. However, it is disadvantageous because of the strength of (1), and it is necessary to keep the spinning speed low. This is not preferable.) In addition, the intermittent spinning time for preventing draining noise and foaming at the start of spinning is also operated at 50 Hz and 60 Hz, respectively.
