  The active water generating device 1 is a device that converts tap water into active water (functional water). Activated water is water that has been functionalized and activated by subjecting water to some kind of treatment, has high purification, sterilization, and deodorization, and is used in various fields such as agriculture and medicine. Yes. Hereinafter, this active water production | generation apparatus 1 is described in detail.

  2 is a side view of the activated water generating apparatus 1, FIG. 3 is a cross-sectional view taken along the line AA in FIG. 2, and FIG. 4 is an explanatory diagram for explaining the inside of the activated water generating apparatus when the flow rate is small. FIG. 5 is an explanatory diagram for explaining the inside of the active water generator when the flow rate is large. In the following description, the upper side in FIG. 2 is described as upper (UP) and the lower side is described as lower (LO).

  As shown in FIG. 1 and FIG. 2, the active water generating apparatus 1 is filled with ceramic-based particles inside a container 2, introduces water into the container 2, and ceramic-based particles inside the container 2. Is a device for obtaining active water by discharging water after flowing the water.

  The container 2 includes a hollow main body portion 3 extending vertically and a lid portion 4 attached above the main body portion 3. An introduction part 5 for introducing water into the container 2 is welded to the lower end of the container 2. Moreover, the discharge part 6 which discharges active water is welded to the upper end of the container 2. The main body part 3, the lid part 4, the introduction part 5, and the discharge part 6 are made of a rust-proof metallic member.

  The main body 3 has a substantially cylindrical shape with an opening on the upper side and an opening continuous with the flow path of the introduction unit 5 on the lower side, and has a space serving as a processing space 11 on the inner side. Further, the upper end edge of the main body portion 3 is provided with a flange portion 13 projecting inward, the lid portion 4 is placed on the flange portion 13, and the lid portion 4 is fixed by a screw 15. An O-ring 17 is disposed between the main body 3 and the lid 4, and the main body 3 and the lid 4, that is, the container 2 is watertight by the O-ring 17. The lid portion 4 is an annular body having an opening continuous with the flow path of the discharge portion 6 at the center.

  A lower partition plate 21 (introduction-side partition plate) is fixed inside the container 2 (main body portion 3) and in the vicinity of the lower end. Further, an upper partition plate 22 (discharge-side partition plate) is fixed inside the container 2 (lid portion 4) and in the vicinity of the upper end. That is, a space surrounded by the lower partition plate 21 and the upper partition plate 22 is formed inside the container 2, and the space is the processing space 11. In the processing space 11, ceramic particles 31 in which small diameter particles 31a having a particle diameter of 2 mm and large diameter particles 31b having a particle diameter of 8 mm are mixed are charged.

  The lower partition plate 21 is formed with a plurality of small holes having a size that allows water to pass therethrough but cannot pass the small-diameter particles 31a. Similarly, the upper partition plate 22 has a plurality of small holes through which water can pass and small diameter particles 31a cannot pass. The lower partition plate 21 and the upper partition plate 22 are not particularly limited as long as a plurality of small holes through which water passes and small diameter particles 31a do not pass are formed. For example, a metal net or the like may be used. .

  As described above, the activated water generating apparatus 1 according to the present embodiment includes the hollow, substantially cylindrical container 2, the lower portion includes the introduction portion 5, the upper portion includes the discharge portion 6, and the lower partition plate 21 and the upper partition inside. A ceramic particle in which a plate 22 is disposed, has a processing space 11 between the upper partition plate 21 and the lower partition plate 22, and a plurality of small diameter particles 31 a and large diameter particles 31 b are mixed in the processing space 11. 31 is inserted.

The ceramic-based particles 31 include silicon and aluminum as main components and an oxide-based ore containing an alkali metal or an alkaline earth metal in addition to these main components. For example, ores such as feldspar, mica and granite can be mentioned. As feldspars, anorthite (NaAlSi ₃ O ₈ ), anorthite (CaAl ₂ Si ₂ O ₈ ), and as mica, phlogopite (KMg ₃ [(AlSi ₃ ) O ₁₀ ] (OH) ₂ ), white cloud Although there is a mother (KAl ₂ [(AlSi ₃ ) O ₁₀ ] (OH) ₂ ), it is not limited thereto.

  And when the active water production | generation apparatus 1 introduce | transduces water into the inside from the lower introduction part 5, water will flow in the process space 11 through the lower partition plate 21, and will flow the ceramic type particle | grains 31 in the process space 11. FIG. Then, it flows to the upper partition plate 22, passes through the upper partition plate 22 and is discharged from the discharge portion 6 to obtain active water.

  The mechanism by which active water is generated is described. The ceramic surface is negatively charged by the interfacial flow potential, and apparently the inside is positive. Therefore, excessive positive charge exists on the ceramic surface due to the Peltier effect. This surplus positive charge acts on water, so that water is positively charged. Further, when water is introduced into the processing space 11 in which the ceramic particles 31 are charged, the ceramic particles 31 flow in the processing space 11. When the ceramic particles 31 flow, the ceramic particles 31 collide or collide with each other in the processing space 11. When the ceramic particles 31 are rubbed or collided with each other, heat is generated on the surface of the particles, and heat transfer occurs due to a temperature difference between the surface of the particles and the center. As a result, the water in contact with the ceramic particles 31 is positively charged. Due to these effects, the water that has passed through the treatment space 11 becomes active water.

  In such an active water generator that introduces water from below and discharges active water from above, the ceramic particles stick to the upper partition plate due to the flow rate of water (it was pressed against the upper partition plate under water pressure). In other words, the ceramic particles do not flow in the processing space and active water cannot be obtained.

  However, in the active water generator 1 in the present embodiment, when the flow rate of the water Wa introduced into the container 2 is small, the large-diameter particles 31b hardly flow and the small-diameter particles 31a flow as shown in FIG. To produce active water. On the contrary, when the flow rate of the water Wa introduced into the container 2 is large, as shown in FIG. 4, the small-diameter particles 31a stick to the upper partition plate 22, but the large-diameter particles 31b flow and activate the active water. Will be generated. Therefore, even if the active water generating device 1 is used in an environment where the flow rate changes, the active water can be always stably generated and the active water generating device 1 can be used in various places.

  As for the particle diameter, the small diameter particle 31a has a diameter of 2 mm and the large diameter particle 31b has a diameter of 8 mm. However, the optimum numerical value in the experiment is illustrated, and the small diameter particle 31a and the large diameter particle 31b are mixed. The same effect can be obtained. Moreover, although the example which mixes the small diameter particle 31a and the large diameter particle 31b was described, what further mixed the particle | grains which are larger than the particle diameter of the small diameter particle 31a and smaller than the particle diameter of the large diameter particle 31b, That is, it is good also as what further mixes an intermediate diameter particle. Further, various particle sizes may be mixed between the small particle size 31a and the large particle size 31b.

  As described above, the home water supply pipe system 100 of the present invention branches the water in the water supply main pipe 101 into the house from the water pipe 190 and the water in the water supply main pipe 101 into the cold water side pipe 121 and the water heater side pipe 125. The active water generator 1 is attached between the water pipe 190 and the cool / warm branch portion 107. And the active water production | generation apparatus 1 is equipped with the ceramic type particle | grains 31 by which at least 2 or more types of ceramic type particle | grains from which a particle size differs are mixed, water is introduce | transduced into the processing space 11 from the downward direction, and the processing space 11 The active water is obtained from above by flowing the ceramic particles 31 inside. The activated water discharged from the activated water generator 1 flows through the cold water side pipe 121 and the hot water supply side pipe 125 and flows into the hot water heater 130 and the water field in the house.

  According to such a domestic water supply pipe system 100 of the present invention, since all water used in the house becomes active water, scales are prevented from adhering to various pipes and the heat exchanger 136 of the water heater 130. it can. In other words, since the active water is charged with cations, it can prevent the calcium that is the basis of the scale from adhering to the pipes and the heat exchanger 136, so the frequency of maintenance and inspection can be reduced, and the water supply can be reduced. The life of various components and machines that come into contact with water can be extended. Moreover, since active water is excellent in washing | cleaning property and deodorizing property, since a stain | pollution | contamination falls quickly by performing washing and cooking using active water, the usage-amount of limited water can be reduced. Furthermore, since two or more kinds of ceramic particles 31 having different particle diameters are used, activated water can be stably generated even when the amount of water flowing through the water supply main pipe 101, the water pressure, and the flow velocity change. .

  And by mixing two kinds (two sizes) of small-diameter particles 31a and large-diameter particles 31b, it is possible to provide an active water generator 1 that can always generate active water stably even if the flow rate changes, It becomes possible to provide the domestic water supply pipe system 100 suitable for the home environment.

  Moreover, the active water production | generation apparatus 1 which can be adapted to most environments can be provided by making the particle diameter of the small diameter particle 31a into 2 mm, and making the particle diameter of the large diameter particle 31b into 8 mm, and the domestic water supply pipe | tube suitable for a household environment can be provided. The system 100 can be provided.

  Note that the home water supply pipe system is not limited to the embodiments described so far. For example, as shown in FIG. 6, as a modified example, a home water supply pipe system 200 having a configuration in which the above-described cold / warm branching portion 107 is not disposed can be used. In addition, the same code | symbol is attached | subjected to what is common in embodiment mentioned above.

  In the domestic water supply pipe system 200 according to the modification of the present embodiment, the active water generating device 1 is disposed downstream of the pressure reducing valve 105, the cold water branching unit 141 is disposed downstream of the active water generating device 1, and the cold water branching unit The hot water heater 130 is arranged downstream of 141. Even in such a configuration, since all tap water in the home can be made active water, the same effect as the above-described embodiment can be obtained.

  Furthermore, as a modified example of a different domestic water supply pipe system, as shown in FIG. 7, the active water generator 1 may be installed in a pipe through which water flows in the hot water heater 130, that is, in the hot water heater side pipe 125. That is, in the domestic water supply pipe system 300 in the present modification, the active water generating device 1 is arranged in the hot water supply side pipe 125 downstream of the cold / hot branching unit 107, and the hot water supply side pipe 125 and the active water generation apparatus 1, a hot water heater 130, a hot water pipe 137, and a hot water branching unit 143 are provided.

  In such a configuration, since the water flowing toward the hot water heater 130 becomes active water, it is possible to prevent the scale from adhering to the heat exchanger 136 to which the scale is most likely to adhere. Therefore, the frequency of maintenance and inspection of the water heater 130 can be reduced, and the life of the water heater 130 can be extended. Moreover, since the active water production | generation apparatus 1 should just be attached to piping near the water heater 130, the active water production | generation apparatus 1 can be easily attached to the existing domestic water supply pipe system.

  In addition, this invention is not limited to embodiment described so far, A various change is possible unless the summary of invention is changed. For example, in the configuration in which the activated water generating device 1 is arranged in the hot water supply side piping 125 shown in FIG. 7, the activated water generating device 1 can also be arranged in the cold water side piping 121. In this case, since all the water flowing in the house can be used as active water, it is possible to prevent the scale from adhering to the piping through which the cold water flows. You can increase your power. Thus, the structure which arrange | positions the activated water production | generation apparatus 1 to the hot water supply side and the cold water side can be used in the situation where the water supply main pipe | tube 101 is buried and it is difficult to attach the activated water production | generation apparatus 1, respectively.
