PROBLEM TO BE SOLVED: To eliminate a fixation of a solenoid valve, while restraining electric power consumption of an emergency power source.SOLUTION: A control part of a toilet bowl washing device on the present embodiment discharges wash water stored in a bowl part by successively inputting an opening signal and a closing signal to a solenoid valve by using an emergency power source when accepting predetermined operation, and afterwards, returns a water level in the bowl part by successively inputting the opening signal and the closing signal again to the solenoid valve by using the emergency power source. The control part comprises a determination processing part and an input processing part. The determination processing part determines the existence of a fixation of the solenoid valve on the basis of at least one of a current characteristic of the solenoid valve when inputting the opening signal of a first time, the current characteristic of the solenoid valve when inputting the closing signal of a first time and the current characteristic of the solenoid valve when inputting the opening signal of a second time. The input processing part inputs the closing signal of a second time to the solenoid valve in a different mode from when there is no fixation when determined that there is the fixation in determination processing.SELECTED DRAWING: Figure 9

【課題】非常用電源の電力消費量を抑えつつ、電磁弁の固着を解消すること。【解決手段】本実施形態に係る便器洗浄装置の制御部は、所定の操作を受け付けた場合に、非常用電源を用いて電磁弁に開信号および閉信号を順次入力することによってボウル部に貯留された洗浄水を排出し、その後、非常用電源を用いて電磁弁に再度開信号および閉信号を順次入力することによってボウル部内の水位を戻す。また、制御部は、判定処理部と、入力処理部とを備える。判定処理部は、１回目の開信号を入力した場合における電磁弁の電流特性、１回目の閉信号を入力した場合における電磁弁の電流特性および２回目の開信号を入力した場合における電磁弁の電流特性の少なくとも１つに基づき、電磁弁の固着の有無を判定する。入力処理部は、判定処理において固着有りと判定された場合に、２回目の閉信号を固着無しの場合と異なる態様で電磁弁に入力する。【選択図】図９
