In the pre-drainage treatment, the control unit 6 turns on the first flow path switch 46, while turns off the second flow path switch 47, and drives the pump 15 in this state for a prescribed time. As a result, the residual water in the circulation flow passage 14 is discharged from the fifth pipe portion 45e and the seventh pipe portion 45g to the drain portion 5.

In addition, when the washing button is pressed, the control unit 6 executes the washing process for a prescribed time. In the cleaning process, the control part 6 energizes the 1st flow path switch 46 and the 2nd flow path switch 47, turns them ON, and inverts the polarity of the negative electrode plate 2d and the positive electrode plate 2e, The pump 15 is driven by applying a prescribed time voltage (reverse voltage) between these electrodes. When the prescribed time elapses, the application of the voltage to the electrolytic cell 2 is stopped, the driving of the pump 15 is stopped, and the energization of the first flow path switch 46 and the second flow path switch 47 is stopped and they are stopped. Turn off. Thereby, the water in the circulation flow path 14 which communicates with the electrolyzer 2 and the electrolyzer 2 is discharged | emitted from the 5th pipe part 45e and the 6th pipe part 45f to the drain part 5.

In addition, in this embodiment, the 1st flow path switch 46 and the 2nd flow path switch 47 are used for the circulation flow path 14 and the drainage flow path (sixth pipe part 45f, 7th pipe part 45g). Since the communication state can be set variably, the water of the circulation flow path 14 can be prevented from flowing in a drain flow path, or the water of the circulation flow path 14 can flow into a drain flow path.

In addition, in this embodiment, since the filter 30 is provided in the water supply port 11 and the water discharge port 13, when a foreign material mixes in the water in the water storage part 4, the foreign material is returned to the main-body part 3; Inflow can be prevented by the filter 30. In addition, the filter 30 can prevent foreign matter from entering the main body portion 3 with the water storage portion 4 separated from the water supply port 11 and the water discharge port 13.

In addition, in this embodiment, the water storage part 4 is isolate | separated by covering the water supply port 11 and the water discharge port 13 with the cover 50 in the state in which the water storage part 4 was isolate | separated from the main-body part 3.
