    • A cleanser feeding mechanism has a cleanser housing portion, a cleanser feeding member for feeding a cleanser housed in the cleanser housing portion, and a synchronous motor for applying a drive force to the cleanser feeding member, and feeds and amount of cleanser corresponding to the number of revolutions of the synchronous motor. A cleanser feeding amount-setting unit sets an amount of cleanser to be fed from the cleanser feeding mechanism. A driving unit applies an AC source voltage of an AC power source to the synchronous motor. A counter counts the number of cycles of the AC source voltage from a timing at which the AC source voltage is applied to the synchronous motor. A reference cycle number-setting unit sets a total cycle number of the AC source voltage which corresponds to a cleanser amount set by the cleanser feeding amount-setting unit. A motor controller compares a count output from the counter with a total cycle number from the reference cycle number-setting unit and stops application of the AC source voltage to the synchronous motor when the count output and the total cycle number coincide with each other.
    • 清洁剂进给机构具有清洁器容纳部分,用于馈送容纳在清洁器容纳部分中的清洁剂的清洁剂进给构件以及用于向清洁剂进给构件施加驱动力的同步电动机,并且对应于数量的进料和量的清洁剂 的同步电机的转数。 清洁剂进料量设定单元设定要从清洁剂进给机构供给的清洁剂的量。 驱动单元将AC电源的AC电源电压施加到同步电动机。 计数器从AC电源电压施加到同步电机的时刻计数AC电源电压的周期数。 参考周期数设定单元设定与清洁剂供给量设定单元设定的清洁剂量对应的交流电源电压的总周期数。 电机控制器将计数器的计数输出与参考循环次数设定单元的总循环次数进行比较,并且当计数输出和总循环次数相互一致时,停止将AC电源电压施加到同步电机。
