Therefore, there is no inconvenience in the above-mentioned slide of the integrated electrolytic processing unit 2 and the support plate 3.

  In order to use this form, as shown in FIG. 6, it is installed outside the water tank T in which the raw water Wa is stored, and the filter 5 and the water pump 6 are connected to the inlet port 14 of the production container 1 from the water tank T. A supply path is provided by a hose, a pipe, and the like, and an annular flow path is provided at the outlet port 14 of the production container 1 up to the water storage tank T. Moreover, as shown in FIG. 7, it installs so that it may submerge in the inside of the water tank T in which raw | natural water Wa was stored, and the water pump 6 is attached to the inlet port 14 of the production | generation container 1 as a submersible pump type with a filter. Or make it built-in. That is, a usage pattern is adopted in which the concentration of the electrolyzed water Wb stored in the water tank T is successively increased by circulating the raw water Wa stored in the water tank T and continuously performing electrolysis. .

In the production container 1 in the circulation path configured as shown in FIGS. 6 and 7, the raw water Wa introduced from the inlet port 14 is guided to the partition wall 16 inside the main body 11 and has a U-shaped folded structure. While passing through the flow path R, the electrolytic treatment unit 2 performs an electrolysis process to form electrolyzed water Wb that is discharged from the outlet port 15 (see FIG. 1).

The raw water Wa filled in the main body part 11 of the closed generation container 1 enters the reaction chamber 213 through the communication hole 216 of the casing 21 of the electrolytic treatment part 2.

When the entire electrolytic treatment section 2 is immersed in the raw water Wa, when the electrode plate 23 on the window hole 214 side of the casing 21 is used as a negative electrode and the electrode 24 on the reaction chamber 213 side is used as a positive electrode, as shown in FIG. The raw water Wa is electrolyzed, hydrogen ions and electrons are generated by the positive electrode plate 24 inside the reaction chamber 213 of the casing 21, pass through the polymer film 22, and are exposed to the window hole 214 of the casing 21. Hydrogen (gas) a is generated by the negative electrode plate 23. Since the hydrogen a forms fine bubbles, it is efficiently dissolved in the raw water Wa, and electrolyzed water Wb made of hydrogen water is generated. When the raw water Wa is electrolyzed, ozone (gas) b is also generated by the positive electrode plate 24. However, ozone b stays inside the reaction chamber 213 of the casing 21 without passing through the polymer film 22, and is discharged from the communication hole 216 of the casing 21 when the staying pressure inside the reaction chamber 213 of the casing 21 increases. The As shown in FIG. 8, the discharged ozone b is not easily dissolved in the raw water Wa because it becomes large bubbles.

This electrolysis treatment is continuously executed by a plurality (eight in the drawing) of the electrolysis processing units 2 arranged along the distribution path R, and a large amount of electrolyzed water Wb composed of high-concentration hydrogen water is generated. Will be. That is, as the outlet port 15 of the production container 1 is approached, the hydrogen concentration is increased. In the circulation path shown in FIGS. 6 and 7, the raw water Wa and the electrolyzed water Wb can be circulated to generate the electrolyzed water Wb composed of higher-concentration hydrogen water.

The electrolytic processing unit 2 that performs the electrolysis treatment protects the entire surface of both surfaces of the polymer film 22 made of a thin film with a sandwich structure in which the electrode plates 23 and 24 are laminated, and the laminated polymer film 22 and the electrode. The plates 23 and 24 are elastically pressed against the stopper 215 of the casing 21 by a spring 25 so as to be able to withstand the water pressure and swinging of the raw water Wa and the electrolytic water Wb. Therefore, similarly to the electrolyzed water generating apparatus according to Patent Document 1, the fragile polymer film 22 and the electrode plates 23 and 24 can be protected by unitization of the electrolytic treatment unit 2 to obtain a high durability performance.

Furthermore, in this embodiment, the casings 21 of the plurality of electrolytic treatment units 2 are stacked and connected by the connection unit 217 and supported by the common support plate 3. Therefore, a plurality of electrolytic treatment parts 2 are integrated with the support plate 3 to protect the polymer film 22 and the electrode plates 23 and 24 that are vulnerable to high-speed raw water Wa and electrolytic water Wb, Higher durability can be obtained.

As described above, it is also possible to generate the electrolyzed water Wb made of ozone water by reversing the polarities of the electrode plates 23 and 24 of the electrolysis processing unit 2 in addition to the illustrated form.

  The electrolyzed water generating apparatus according to the present invention can be applied from a small household one to a large industrial one.
