- the length between the two end portions 25b can be changed.
- the first end 25a of the multi-stage hollow pipe is connected to the third shaft 29, and the second end 25b of the multi-stage hollow pipe (the open / close pipe of the pitcher opening / closing section) is connected to the fourth shaft 30 and the third shaft.
- the drive unit 26 can change the length of the multistage hollow pipe 25 by changing the distance between the third shaft 29 and the fourth shaft 30.
- the open / close valve 23 for the electrolytic water outlet and the open / close pipe 25 for the pitcher opening / closing section are arranged on the same straight line.
- the drive unit 26 supplies the electrolyzed water generated in the electrolytic cell 15 to the pitcher.
- the drive unit 26 uses the anode unit in FIG.
- the operation performed before pouring the raw material aqueous solution into the electrolytic cell will be described.
- the drive unit 26 drives (shrinks the multistage hollow pipe) until the third shaft 29 and the fourth shaft 30 contact each other.
- the open / close valve 22 of the electrolytic water outlet and the open / close pipe 24 of the pitcher opening / closing section are closest to each other, and the open / close valve 22 of the electrolytic water outlet moves downward in the electrolytic cell 15 to move the electrolytic water outlet 20 Close and open
- the closed pipe 24 moves upward in the pitcher opening / closing part 2 and closes the opening 3.
- the drive unit 26 moves the third shaft 29 and the fourth shaft 30 until they are farthest from each other (extends the multistage hollow pipe). Due to this operation, the open / close valve 23 for the electrolytic water outlet and the open / close pipe 25 of the pitcher opening / closing part are farthest from each other, and the open / close valve 23 for the electrolytic water outlet moves upward in the electrolytic cell 15 to move the electrolytic water outlet 21
- the opening / closing pipe 25 of the pitcher opening / closing part moves downward, contacts the connecting part 2b of the pitcher opening / closing part 2, and opens the opening 3.
- each drive unit connected to the cathode part and the anode part performs an operation of shrinking the multistage hollow pipe before supplying the raw material aqueous solution to the electrolytic cell 15, and the cathode water and the anode water generated in the cathode part and the anode part are reduced.
- the electrolyzed water can be generated by the electrolyzed water generating device, and the generated electrolyzed water can be stored by the pitcher.
- the performance of the electrolyzed water generator 10 was evaluated from the characteristics of electrolyzed water obtained when electrolysis was repeated. Specifically, 2 liters of raw material aqueous solution was placed in the electrolytic cell, and electrolysis was performed for 10 minutes to generate electrolyzed water. Then, the effective chlorine content of the obtained anodic electrolyzed water was examined. Under this condition, when the electrolyzed water generating apparatus 10 operates normally, the pH of the acidic electrolyzed water is 2.4 to 2.6 and the effective chlorine content is 40 to 60 ppm.
- the electrolyzed water generating device having the above-described electrode set structure with a diaphragm can stably produce electrolyzed water having desired characteristics even when electrolyzed water is repeatedly generated. Power of s.
- the performance of the electrolyzed water in the electrolyzed water generating apparatus 10 is deteriorated, the performance of the electrolyzed water can be recovered by removing the scale attached to the electrodes in the cleaning mode.
- the cleaning mode means that when the electrolysis efficiency is reduced, the polarity of the electrode plate is switched and then the electrolysis is performed to dissolve the scale attached to the electrode plate to clean the electrode and to reduce the electrolysis. A process that restores efficiency.
- the configuration used in the above description is an example, and the configuration and arrangement can be changed as appropriate as long as the technical idea of the present invention is satisfied.
- a check valve may be used instead of the on-off valve.
- the shape of the adsorbent can be changed at any time.
