The position detection can also be judged directly through detecting the electric parameter variation of the motor without a hardware form, the fluctuation of the electric parameters can be generated due to the eccentric condition when the motor rotates, the bra fixing mode in the example generates larger eccentric amount under the condition that clothes are wetted, and the relative position of the bra is easy to judge through the fluctuation of the electric parameters. Therefore, it is preferable to apply a position detection form in which the water inlet means is combined with the shower means in the above-described water inlet process, and the laundry is wetted while the water is supplied. It should be noted that the measurement can be performed without wetting the laundry, which is to increase the accuracy of detecting the fixed orientation.
