を提供する。DISCLOSURE OF INVENTION Problems to be Solved by the Invention In an electrolyzed water generator such as an alkaline ionized water generator or a strong electrolyzed water generator,
When general tap water or the like is electrolyzed, an electrolyte such as calcium in the water is deposited on the diaphragm surface on the cathode side or the cathode to inhibit electrolysis. Therefore, a method is adopted in which the electrolytic polarity is reversed and the electrolyte deposited on the cathode side is turned to the anode side to energize for cleaning. The amount of the electrolyte deposited during electrolysis greatly differs depending on the concentration of the electrolyte contained in the raw water and the strength of the electrolysis. Fig. 3 shows the difference between the calcium / magnesium hardness (ppm) and the electrical conductivity of the raw water that we surveyed for tap water throughout Japan. Therefore, the deposited electrolyte may not be sufficiently removed by cleaning by polarity reversal in a constant reversal cycle or cleaning with a constant amount of water. Therefore, there is provided a cleaning method of an electrolysis device that can perform stable electrolysis for a long period of time by performing cleaning according to the hardness of raw water to be supplied.
