Title:
ELECTROLYTIC WATER DISCHARGE DEVICE
Document Type and Number:
Japanese Patent JP2019148081
Kind Code:
A
Abstract:
To suppress deposition of scales inside a flow channel in an electrolytic water discharge device generating electrolytic water by electrolyzing water and discharging generated electrolytic water.SOLUTION: An electrolytic water discharge device of one embodiment in this disclosure comprises a water discharge portion, an electrolytic water generating portion, a flow channel, an on-off valve and a control portion. The electrolytic water generating portion generates electrolytic water by electrolyzing water using a first electrode and a second electrode. The flow channel connects the electrolytic water generating portion with the water discharge portion. The on-off valve can open and close the flow channel. The control portion performs: voltage applying processing which makes the electrolytic water generating portion perform electrolyzation by applying voltage between the first electrode and the second electrode; and polarity inversion processing which reverses polarity of voltage applied between the first electrode and the second electrode. The control portion determines whether pH of liquid inside the flow channel is equal to or smaller than a threshold value after a start of the voltage applying processing and, after determining that pH is equal to or smaller than the threshold value, controls the on-off valve to close the flow channel.SELECTED DRAWING: Figure 5
