<Industrial Application Field> The present invention relates to an apparatus for producing sterilized water by electrolysis. <Prior Art and Problems> Sterile water having sterilizing properties is widely used as washing water for tableware and washing water for surgical operations. Conventionally, sterile water is obtained by adding disinfectants such as hydrogen peroxide to tap water, but this not only increases costs due to the use of expensive disinfectants, but also makes it difficult to clean the body of patients undergoing surgery. When used, there was a risk that the side effects of the stabilizer added to hydrogen peroxide could damage the tissue at the injured site and worsen the postoperative course. In addition, since conventional sterilized water is given sterilization by chemicals, it cannot be used as food preservation water (for example, tofu preservation water), and its uses are limited. The present invention has been made in view of the above-mentioned conventional circumstances, and an object of the present invention is to provide a sterilized water manufacturing apparatus that can obtain sterilized water without adding a sterilizing agent. <Means for Solving the Problems> The sterilized water production apparatus according to the present invention, which achieves the above objects and solves the above problems, includes installing a cathode plate and an anode plate in an electrolytic cell with a partition between them. , a water conduit for supplying electrolyte to the electrolytic tank is connected, and an electric circuit for applying a direct current between the negative and anode plates is connected, and a cathode generated by electrolysis is placed in the cathode plate chamber defined by the partition. A cathode water tube for discharging water is connected to the anode plate chamber defined by the partition, and an anode water tube for discharging sterilizing anode water produced by electrolysis is connected to the anode plate chamber defined by the partition. <Operation> The pH of the anode water produced in the anode plate chamber by electrolyzing the electrolytic solution decreases, and oxidizing substances are generated in the anode plate chamber. Therefore, the anode water is acidic and has residual oxidizing power.
Provides bactericidal properties. <Example> An example of the present invention will be described based on the drawings. FIG. 1 is a block diagram of a sterilized water production apparatus according to the present invention, and FIG. 2 is a block diagram of its electric circuit. As shown in FIG. 1, an anode plate 3 and a cathode plate 4 are placed facing each other with a partition (diaphragm) 5 in between, in an electrolytic cell 1 to which a water conduit 2 is connected. and an anode plate chamber 7 defined by the partition 5 and housing the anode plate 3;
is connected to the anode water tube 8 and guided to the outside of the electrolytic cell 1, while the cathode plate chamber 9 defined by the partition 5 and housing the cathode plate 4 is connected to the cathode water tube 10 and guided to the outside of the electrolytic cell 1. being guided to. An electric circuit for applying direct current is connected between the anode plate 3 and the cathode plate 4, as shown in FIG. That is, the primary side of the transformer 11 is provided with a body switch 12, a fuse 13, and a power lamp 14, and the secondary side of the transformer 11 is provided with a rotary switch 15 for switching taps, a rectifier stack 16 for supplying direct current, Smoothing capacitor 17
is provided. According to the manufacturing apparatus having the above configuration, when the electrolytic solution is connected and supplied from the water conduit pipe 2 into the electrolytic cell 1, and the vessel switch 12 is closed to apply a direct current between the electrode plates 3 and 4, The electrolyte is electrolyzed between the electrode plates 3 and 4, and the anode water (sterilized water) generated in the anode plate chamber 7 and having sterilizing properties is continuously obtained from the anode water tube 8. In addition, with the rotary switch 15, the electrode plate 3,
By adjusting the electrolytic voltage between
The bactericidal strength can be appropriately selected by adjusting the pH level. Generally, under acidic or alkaline conditions,
Proteins constituting bacterial cell membranes and enzyme proteins that play a role in substance metabolism are denatured, and as a result, bacterial physiological activity is inhibited under acidic or alkaline conditions. This is a well-known fact, for example, in vinegar used for food preservation. Here, if we focus on the cathode water discharged from the cathode water tube 10, the liquid nature of the cathode water is alkaline, but as shown in the following table, although it has a considerable antibacterial effect, it cannot be said that it has a strong bactericidal effect. On the other hand, the anode water obtained from the anode water tube 8 is acidic and has residual oxidizing power due to the oxidizing substances generated near the anode plate 3. Therefore, the anode water has an extremely strong It has a bactericidal effect.

A chemical tank 28 containing a neutralizer and an electrolytic reaction accelerator and a water pump 29 are interposed in the tank 0. Therefore, the anode water is circulated and used without being discharged to the outside, and only anode water (sterilized water) can be obtained. Note that the other configurations and operations are the same as the embodiment shown in FIGS. 1 and 2. Here, it is known that when a P-type oxide semiconductor is used as an electrode, chemically active oxygen species are adsorbed on the surface of the electrode. Therefore, when a P-type oxide semiconductor is used as the anode plate 3, oxidizing substances can be generated more efficiently than when a normal metal electrode plate is used, and anode water with stronger bactericidal properties can be obtained. be able to. <Effects of the Invention> According to the sterilized water production apparatus according to the present invention, sterilized water can be continuously obtained without adding a sterilizing agent. Since no disinfectant is used, running costs are reduced, and the sterile water can be safely used as surgical cleaning water or food storage water.
