[Installation / removal of electrolytic cell unit]
Next, attachment / detachment of the electrolytic cell unit 20 to the unit fixture 70 will be described in detail.

  When attaching the electrolytic cell unit 20 to the unit fixture 70, as shown in FIG. 1, the operator attaches the round head screws 35 and 35 (see FIG. 6) of the electrolytic cell 21 to the electrolytic cell of the first divided frame 13. The electrolytic cell 21 is slid downward so that the locking portion 22j (see FIG. 6) is inserted into the support hole 13a and is retained by the retaining portion 13d of the electrolytic cell support hole 13a. As a result, the electrolytic cell 21 is locked and supported by the first divided frame 13. Thereafter, the operator screw-fixes the electrolytic cell 21 to the first divided frame 13 by screwing screws 36 and 36 (see FIG. 4) passing through the screw insertion portion 22g into the screw holes 13b and 13b. Next, the operator holds the holding portion 28d of the support member 28, and the connection tools 24e, 24e of the water supply pipes 24, 24 and the connection tools 25e, 25e of the water discharge pipes 25, 25 are connected to the double cross line valve 50, respectively. The fixing tool 26 is moved to the right side and pushed in so as to be inserted into the portions 57, 57, 57, 57. Thereafter, the operator screws and fixes the fixing plate 27 and the unit fixture 70 with the two screws 33 and 33.

  When removing the electrolytic cell unit 20 from the unit fixture 70, the operator loosens the two screws 33, 33, releases the screwing between the unit fixture 70 and the fixing plate 27, and holds the grip portion 28 d. Then, the connectors 24e and 24e of the water supply pipes 24 and 24 and the connectors 25e and 25e of the water discharge pipes 25 and 25 are removed from the double cross line valve 50. Next, after releasing the fastening of the screws 36, 36, the electrolytic cell 21 is lifted up to release the retaining portion 13 d of the locking portion 22 j (see FIG. 6), and then the electrolytic cell 21 is removed. The electrolytic cell 21 is removed from the first divided frame 13 by pulling it out to the left side.

  As described above, according to the present embodiment, the connection tools 24e, 24e of the water supply pipes 24, 24 and the connection tools 25e, 25e of the water discharge pipes 25, 25 are fixed to the fixing tool 26, so that a single screwing operation can be performed. Four connecting tools 24e, 24e, 25e, 25e can be attached / detached to / from the connecting portions 57, 57, 57, 57. That is, the water supply pipes 24, 24 and the water discharge pipes 25, 25 can be attached / removed simultaneously and easily. Moreover, since the connection tool 24e of the water supply pipe 24 and the connection tool 25e of the water discharge pipe 25 can be fixed to the fixing tool 26 in advance, the water supply is performed when the operator attaches the electrolytic cell unit 20 (electrolytic cell 21) to the apparatus main body. It is possible to prevent the attachment positions of the pipe 24 and the water discharge pipe 25 from being mistaken.

  Furthermore, when the fixing tool 26 is screwed to the unit fixing tool 70, the electrolytic cell 21 can be fixed to the first divided frame 13 prior to that, so that the fixing tool 26 is screwed while holding the electrolytic cell 21. There is no need to do. Thereby, the workability of the operator is further improved.

  When removing the electrolytic cell unit 20, the order of removing the fixture 26 and removing the electrolytic cell 21 may be reversed. For example, when water remains in the electrolytic cell 21, water leakage into the housing 11 can be prevented by removing the electrolytic cell 21 first.

[Other Embodiments]
While the preferred embodiments of the present invention have been described above, various modifications are possible.

  For example, in the embodiment, an example in which two water supply pipes 24 and 24 and two water discharge pipes 25 and 25 are provided has been described, but one water supply pipe and one water discharge pipe may be provided.

In that case, what is necessary is just to adjust the magnitude | size of the retaining hole 27e formed in the fixing plate 27 of the fixing tool 26 according to the outer diameter of the connecting tool 24e and the connecting tool 25e.

  In the above embodiment, the grip portion 28d of the support member 28 may be omitted. At this time, the first support portion 28b functions as a support member for supporting the water supply pipe 24 and the water discharge pipe 25 at the retaining position, and when the operator moves the fixture 26 in the attaching / detaching direction to the apparatus main body. It also has a function as a gripping part for gripping.

  In the present disclosure, when each electrolytic cell 21 is attached, each electrolytic cell 21 is locked and supported by the first divided frame 13 and then screwed and fixed to the first divided frame 13 by screws 36 and 36. The screws 36 and 36 may not be screwed and fixed. For example, each electrolytic cell 21 may be fixed by clipping, or may be fixed by closing the attachment door 12. However, the electrolytic cell 21 can be stably locked and supported by the first divided frame 13 when the electrolytic cell 21 is fixed by the screws 36 and 36.

  Since the electrolyzed water generating apparatus according to the present disclosure enables the electrolytic cell replacement operation to be easily and reliably performed, it is useful in food-related, medical-related, and agricultural-related fields that use a large amount of electrolyzed hydrogen water. is there.
