"Outline of electrolyzed water supply system"
In the present embodiment, an electrolyzed water supply system that supplies electrolyzed water (acidic water, alkaline water) to a plurality of sections (for example, shared facilities, residential facilities, and dedicated facilities) in each of the above-described levels (floors) 1, 2, and 3 Is assumed. The electrolyzed water supply system includes an electrolyzed water production apparatus 4, electrolyzed water dilution means 5, 6, an electrolyzed water supply pipe 7, an electrolyzed water supply network 8, and a water supply control device 9, as shown in FIGS. And.

  The electrolyzed water production apparatus 4 is configured to be able to produce electrolyzed water (acidic water, alkaline water). In this case, the water supply control device 9 controls the electrolyzed water production device 4 (for example, a water supply mechanism 21 described later), so that the production state of the electrolyzed water (acidic water, alkaline water) (for example, production amount, production speed, etc.) Has been adjusted. In the drawing, one electrolyzed water production apparatus 4 is shown as an example. In this case, you may apply the some electrolyzed water manufacturing apparatus 4 according to the scale and structure of an above-mentioned apartment building (high-rise apartment).

  The electrolyzed water dilution means 5 and 6 are configured to be able to dilute electrolyzed water (acidic water, alkaline water) produced by the electrolyzed water producing apparatus 4 (see FIG. 2). As an example, the drawing shows one alkaline water (electrolyzed water) diluting means 5 for diluting alkaline water and one acidic water (electrolyzed water) diluting means 6 for diluting acidic water. Yes. In this case, a plurality of electrolyzed water dilution means 5 and 6 may be applied according to the number of the electrolyzed water production apparatuses 4 described above and the scale and structure of the collective building (high-rise apartment).

  The electrolyzed water supply pipe 7 is connected to the electrolyzed water dilution means 5 and 6. The electrolyzed water supply pipe 7 is configured to be able to supply electrolyzed water (acidic water, alkaline water) to a plurality of levels (floors). In the drawing, one electrolyzed water supply pipe 7 is shown as an example. In this case, a plurality of electrolyzed water supply pipes 7 may be applied according to the number of the above-described electrolyzed water dilution means 5, 6 and the scale and structure of the apartment building (high-rise apartment).

  In addition, what is necessary is just to supply acidic water and alkaline water alternately, when the one electrolyzed water supply piping 7 is comprised (refer FIG. 1). When the alkaline water supply pipe and the acidic water supply pipe are configured separately (not shown), it is possible to supply alkaline water and acidic water simultaneously.

  The electrolyzed water supply network 8 is connected to the electrolyzed water supply pipe 7. The electrolyzed water supply network 8 extends along each level (floor). The electrolyzed water supply network 8 is constructed to be able to supply electrolyzed water (acidic water, alkaline water) to a plurality of sections (for example, shared facilities, residential facilities, dedicated facilities) for each level (floor). As an example, the drawing shows one electrolyzed water supply network 8 (open arrow) for each layer (floor). In this case, a plurality of electrolyzed water supply networks 8 may be applied according to the number of the electrolyzed water supply pipes 7 described above and the scale and structure of the apartment building (high-rise apartment).

  In addition, when the one electrolyzed water supply network 8 is comprised (refer FIG. 1), what is necessary is just to supply acidic water and alkaline water alternately. When the acidic water supply network and the alkaline water supply network are configured separately (not shown), it becomes possible to supply acidic water and alkaline water simultaneously.

"Characteristics of electrolyzed water supply system"
In the electrolyzed water supply system of the present embodiment, the electrolyzed water production apparatus 4 and the electrolyzed water dilution means 5 and 6 are provided in a hierarchy (floor) 1 for supplying electrolyzed water (acidic water, alkaline water) through the electrolyzed water supply pipe 7. , 2 and 3 above the floor (floor). As an example in the drawing, the electrolyzed water production apparatus 4 and the electrolyzed water diluting means 5 and 6 include a hierarchy 10 above the uppermost floor 3 in which the above-described dedicated facilities (for example, the pool 3a and the rest room 3b) are partitioned. (For example, it is installed on the rooftop floor 10).

  The electrolyzed water supply pipe 7 extends along the direction of gravity. As an example, the drawing shows an electrolyzed water supply pipe 7 extending straight and parallel along the direction of gravity. The electrolyzed water supply pipe 7 extends from the electrolyzed water dilution means 5, 6 on the rooftop floor 10 to the lower floor 1 through the uppermost floor 3 or the middle floor 2. The electrolyzed water supply pipe 7 extends separately from a tap water pipe (not shown) described later.

  In this case, the electrolyzed water (acidic water, alkaline water) freely falls in the electrolyzed water supply pipe 7. Here, if the electrolyzed water (acidic water, alkaline water) can be freely dropped, the electrolyzed water supply pipe 7 does not necessarily have to extend in parallel and straight along the direction of gravity. For example, the electrolytic water supply pipe 7 can be inclined or curved so as to avoid an obstacle (not shown) in a building. In short, the electrolyzed water supply pipe 7 can be arbitrarily configured according to the use environment and the purpose of use, and has a high degree of design freedom.

  According to the configuration described above, the electrolyzed water production apparatus 4 produces electrolyzed water (acidic water, alkaline water). The produced electrolyzed water (acidic water, alkaline water) is diluted to a preset concentration by the electrolyzed water dilution means 5 and 6. The diluted electrolyzed water (acidic water, alkaline water) falls freely along the electrolyzed water supply pipe 7. By free-falling, the diluted electrolyzed water (acidic water, alkaline water) flows into the electrolyzed water supply network 8 extending along the respective floors (floors) 1, 2, 3.

  That is, for example, the diluted electrolyzed water can be distributed to the electrolyzed water supply networks 8 of the respective floors (floors) 1, 2, and 3 without separately providing a water supply mechanism such as a pump. Thus, the diluted electrolyzed water (acidic water, alkaline water) is supplied to a plurality of sections (for example, shared equipment, residential equipment, dedicated equipment) in each level (floor) 1,2,3. The diluted electrolyzed water (acidic water, alkaline water) supplied to each section is taken into the section through the above-described water intake (not shown).

Hereinafter, the electrolyzed water supply system will be specifically described.
"Electrolyzed water production device 4"
The electrolyzed water production apparatus 4 includes a three-chamber electrolytic tank 11. The electrolytic cell 11 has an intermediate chamber (electrolytic chamber) 12 and an anode chamber 13 and a cathode chamber 14 adjacent to both sides of the intermediate chamber 12. The intermediate chamber 12 and the anode chamber 13 are partitioned by an anion exchange membrane 15. The intermediate chamber 12 and the cathode chamber 14 are partitioned by a cation exchange membrane 16. An anode 17 is provided in the anode chamber 13. A cathode 18 is provided in the cathode chamber 14. The anode 17 and the cathode 18 have a rectangular shape with the same size. The anode 17 and the cathode 18 are disposed on both sides of the intermediate chamber 12 and face each other.

  The electrolyzed water production apparatus 4 includes a power source 19, an electrolytic solution supply mechanism 20, and a water supply mechanism 21. The power source 19 is configured to be able to apply a positive voltage to the anode 17. The power source 19 is configured to be able to apply a negative voltage to the cathode 18.

  The electrolytic solution supply mechanism 20 includes a salt water tank 22, a supply pipe 23, a water supply pump 24, and a discharge pipe 25. The salt water tank 22 is configured to be able to generate saturated salt water (electrolytic solution). The supply pipe 23 extends so as to connect the salt water tank 22 and the lower part of the intermediate chamber 12. A water supply pump 24 is connected to the supply pipe 23. The discharge pipe 25 extends so as to connect the upper part of the intermediate chamber 12 and the salt water tank 22.

  The water supply mechanism 21 includes a water supply source 26, a water supply pipe 27, an alkaline water pipe 28, an acidic water pipe 29, a gas-liquid separator 30, and a water supply valve 31. The water supply source 26 is configured to be able to supply water (electrolyte solution) such as tap water and softened water. Here, the water softened water is obtained by softening tap water with a water softener (not shown). Moreover, the above-mentioned saturated salt can also be produced | generated using water softening process water.

  The water supply pipe 27 extends to connect the water supply source 26 to the lower portions of both the anode chamber 13 and the cathode chamber 14. The alkaline water pipe 28 is connected to the upper part of the cathode chamber 14. The acidic water pipe 29 is connected to the upper part of the anode chamber 13. The gas-liquid separator 30 is connected to the alkaline water pipe 28. The water supply valve 31 is connected between the water supply source 26 and the water supply pipe 27. The water supply valve 31 is controlled to open and close by the water supply control device 9.

  In the drawing, a water receiving tank 32 is applied as an example of the water supply source 26. The water receiving tank 32 is provided on the rooftop floor 10 on which the electrolyzed water production apparatus 4 is installed. The water receiving tank 32 is configured to be able to temporarily store tap water pumped up by a pump 33 (see FIG. 1). The tap water stored in the water receiving tank 32 is supplied to both the anode chamber 13 and the cathode chamber 14 as electrolyzed water. The water receiving tank 32 is not necessarily required. For example, a configuration in which tap water pumped by the pump 33 can be directly supplied to the electrolyzed water production apparatus 4 (the anode chamber 13 and the cathode chamber 14) is applied as a water supply source. May be.

  In such a configuration, the water pump 24 is driven. Thereby, saturated salt water (hereinafter referred to as salt water) generated in the salt water tank 22 flows into the intermediate chamber 12 from the supply pipe 23 through the lower portion of the intermediate chamber 12. At this time, the water supply valve 31 is controlled to be opened by the water supply control device 9. As a result, the water supplied from the water supply source 26 flows into the anode chamber 13 and the cathode chamber 14 from the water supply pipe 27 through the lower portions of both the anode chamber 13 and the cathode chamber 14. At the same time, a positive voltage is applied from the power source 19 to the anode 17 and a negative voltage is applied to the cathode 18.

  At this time, sodium ions (cations) ionized in the salt water flowing into the intermediate chamber 12 are attracted to the cathode 18. Sodium ions (cations) pass through the cation exchange membrane 16 and flow into the cathode chamber 14. In the cathode chamber 14, water is electrolyzed at the cathode 18. Thereby, hydrogen gas and sodium hydroxide aqueous solution are produced | generated. The generated hydrogen gas and sodium hydroxide aqueous solution flow out of the cathode chamber 14 into the alkaline water pipe 28 and then are separated into hydrogen gas and sodium hydroxide aqueous solution by the gas-liquid separator 30. The separated sodium hydroxide aqueous solution (that is, alkaline water) is supplied to the alkaline water (electrolyzed water) dilution means 5 described later through the alkaline water pipe 28.

  Further, chlorine ions (anions) ionized in the salt water flowing into the intermediate chamber 12 are attracted to the anode 17. Chlorine ions (anions) pass through the anion exchange membrane 15 and flow into the anode chamber 13. In the anode chamber 13, chlorine ions (anions) are reduced. At this time, chlorine gas is generated. The generated chlorine gas reacts with water in the anode chamber 13. Thereby, hypochlorous acid and hydrochloric acid are produced. Acidic water is generated in the anode chamber 13 by the generated hypochlorous acid and hydrochloric acid. The generated acidic water is supplied to the acidic water (electrolyzed water) dilution means 6 described later through the acidic water pipe 29.

  The salt water flowing into the intermediate chamber 12 from the lower portion of the intermediate chamber 12 flows out from the upper portion of the intermediate chamber 12 and then returns to the salt water tank 22 through the discharge pipe 25. Thus, a series of electrolytic solution (salt water) circulation paths from the salt water tank 22 through the supply pipe 23 and the intermediate chamber 12 of the electrolytic cell 11 to the salt water tank 22 again from the discharge pipe 25 are configured.

"Electrolytic water dilution means 5, 6"
The alkaline water (electrolyzed water) dilution means 5 has an alkaline water tank 5t. The alkaline water tank 5t has a sealed water storage space (not shown). The alkaline water pipe 28 is connected to the alkaline water tank 5t. In such a configuration, the alkaline water (electrolyzed water) supplied through the alkaline water pipe 28 described above is temporarily stored in the water storage space of the alkaline water tank 5t.

  A first dilution pipe 34 is connected to the alkaline water tank 5t. The first water supply source 26 is connected to the first dilution pipe 34. A first dilution valve 35 is connected between the water supply source 26 and the first dilution pipe 34. The first dilution valve 35 is controlled to open and close by the water supply control device 9.

  The acidic water (electrolyzed water) dilution means 6 has an acidic water tank 6t. The acidic water tank 6t has a sealed water storage space (not shown). The acidic water pipe 29 is connected to the acidic water tank 6t. In such a configuration, the acid water (electrolyzed water) supplied through the acid water pipe 29 is temporarily stored in the water storage space of the acid water tank 6t.

  A second dilution pipe 36 is connected to the acidic water tank 6t. The above-described water supply source 26 is connected to the second dilution pipe 36. A second dilution valve 37 is connected between the water supply source 26 and the second dilution pipe 36. The second dilution valve 37 is controlled to open and close by the water supply control device 9.

  A first capacity monitor 38 is provided in the alkaline water tank 5t. The 1st capacity | capacitance monitor 38 is comprised so that the capacity | capacitance (water storage amount) of the alkaline water (electrolyzed water) stored in the alkaline water tank 5t (water storage space) can be monitored. The 1st capacity | capacitance monitor 38 monitors the capacity | capacitance (water storage amount) of the alkaline water (electrolyzed water) with respect to the water line (not shown) preset in the alkaline water tank 5t (water storage space), for example. In addition, since the capacity | capacitance (water storage amount) of the alkaline water tank 5t is set according to the scale of the above-mentioned collective building (high-rise apartment) and the amount of alkaline water (electrolyzed water) used, for example, it is particularly limited here. do not do.

  In this case, when the capacity (amount of stored water) of alkaline water (electrolyzed water) is below the water line, the water supply control device 9 controls the electrolyzed water production device 4 based on the output of the first capacity monitor 38. That is, the water supply control device 9 controls the water supply valve 31 and the first dilution valve 35 to open. At this time, the water supplied from the water supply source 26 flows into the cathode chamber 14 through the water supply pipe 27. Alkaline water (electrolyzed water) generated in the cathode chamber 14 is supplied to the alkaline water tank 5t through the alkaline water pipe 28. At the same time, the water supplied from the water supply source 26 flows into the alkaline water tank 5t through the first dilution pipe 34. Thereby, alkaline water (electrolyzed water) having a preset concentration is automatically produced and stored in the alkaline water tank 5t.

  Here, the concentration of the alkaline water (electrolyzed water) is set so that the sodium concentration is in the range of 0.1 ppm to 2500 ppm, preferably in the range of 1 ppm to 500 ppm, and more preferably in the range of 10 ppm to 300 ppm. .

  On the other hand, when the capacity (storage amount) of alkaline water (electrolyzed water) exceeds the draft, the water supply control device 9 controls the electrolyzed water production device 4 based on the output of the first capacity monitor 38. . That is, the water supply control device 9 controls the water supply valve 31 and the first dilution valve 35 to be closed. Thereby, the production of alkaline water (electrolyzed water) is automatically stopped.

  Thus, based on the output of the first capacity monitor 38, the water supply control device 9 controls the opening and closing of the water supply valve 31 and the first dilution valve 35, respectively. Thereby, in the alkaline water tank 5t (water storage space), the capacity (water storage amount) or concentration of the alkaline water (electrolyzed water) is always maintained constant. As a result, it becomes possible to utilize the alkaline water (electrolyzed water) at any time without omission for various uses in daily life.

  The acidic water tank 6t is provided with a second capacity monitor 39. The 2nd capacity | capacitance monitor 39 is comprised so that the capacity | capacitance (water storage amount) of the acidic water (electrolyzed water) stored in the acidic water tank 6t (water storage space) can be monitored. The 2nd capacity | capacitance monitor 39 monitors the capacity | capacitance (water storage amount) of the acidic water (electrolyzed water) with respect to the waterline (not shown) preset in the acidic water tank 6t (water storage space), for example. In addition, since the capacity | capacitance (water storage amount) of the acidic water tank 6t is set according to the scale of the above-mentioned collective building (high-rise apartment) and the usage amount of acidic water (electrolyzed water), for example, it is particularly limited here. do not do.

  In this case, when the capacity (water storage amount) of the acidic water (electrolyzed water) is below the water line, the water supply control device 9 controls the electrolyzed water production device 4 based on the output of the second capacity monitor 39. That is, the water supply control device 9 controls the water supply valve 31 and the second dilution valve 37 to open. At this time, the water supplied from the water supply source 26 flows into the anode chamber 13 through the water supply pipe 27. The acidic water (electrolyzed water) generated in the anode chamber 13 is supplied to the acidic water tank 6t through the acidic water pipe 29. At the same time, the water supplied from the water supply source 26 flows into the acidic water tank 6t through the second dilution pipe 36. Thereby, acidic water (electrolyzed water) having a preset concentration is automatically produced and stored in the acidic water tank 6t.

  Here, the concentration of the acidic water (electrolyzed water) is set so that the concentration of hypochlorous acid is in the range of 10 ppm to 200 ppm, preferably in the range of 10 ppm to 100 ppm, and more preferably in the range of 30 ppm to 60 ppm. The

  On the other hand, when the capacity | capacitance (water storage amount) of acidic water (electrolyzed water) has exceeded the water line, the water supply control apparatus 9 controls the electrolyzed water manufacturing apparatus 4 based on the output of the 2nd capacity | capacitance monitor 39. . That is, the water supply control device 9 controls the water supply valve 31 and the second dilution valve 37 to be closed. Thereby, manufacture of acidic water (electrolyzed water) is stopped automatically.

  Thus, based on the output of the second capacity monitor 39, the water supply control device 9 controls the opening and closing of the water supply valve 31 and the second dilution valve 37, respectively. Thereby, in the acidic water tank 6t (water storage space), the capacity (water storage amount) or concentration of the acidic water (electrolyzed water) is always maintained constant. As a result, the acidic water (electrolyzed water) can be utilized without omission for various uses in daily life.

"Electrolyzed water supply pipe 7"
A first connection pipe 40 is connected to the alkaline water tank 5t. A first on-off valve 41 is connected to the first connection pipe 40. The first on-off valve 41 is controlled to open and close by the water supply control device 9. In this configuration, the first on-off valve 41 is controlled to open by the water supply control device 9. Thereby, the diluted alkaline water set to the above concentration can be sent out through the first connection pipe 40.

  A second connection pipe 42 is connected to the acidic water tank 6t. A second on-off valve 43 is connected to the second connection pipe 42. The second on-off valve 43 is controlled to open and close by the water supply control device 9. In such a configuration, the second on-off valve 43 is controlled to be opened by the water supply control device 9. Thereby, the diluted acidic water set to the above concentration can be sent out through the second connection pipe 42.

  Here, when the alkaline water supply pipe and the acidic water supply pipe are configured separately (not shown), the alkaline water supply pipe is connected to the extension of the first connection pipe 40, and the second connection pipe 42 is connected to the second connection pipe 42. An acidic water supply pipe is connected to the extension destination. On the other hand, when one electrolyzed water supply pipe 7 is configured (see FIG. 1), the first and second connection pipes 40 and 42 are merged into one at the extension (not shown). . The one electrolyzed water supply pipe 7 is connected to this merged portion.

  In any case, the electrolyzed water supply pipe 7 extends over the lower floor 1 through the uppermost floor 3 or the middle floor 2. The electrolyzed water supply pipe 7 extends while avoiding the tap water pipe. In such a configuration, the diluted electrolyzed water (acidic water, alkaline water) sent through the first and second connecting pipes 40 and 42 falls freely in the electrolyzed water supply pipe 7. At this time, the dilute electrolyzed water (acidic water, alkaline water) flows into the electrolyzed water supply network 8 extending along each level (floor) by free-falling.

"Electrolyzed water supply network 8"
The electrolyzed water supply network 8 is connected to the above-described electrolyzed water supply pipe 7. For this reason, according to the configuration of the electrolyzed water supply pipe 7, one or more electrolyzed water supply networks 8 are constructed for each of the floors (floors) 1, 2, and 3. For example, when one electrolyzed water supply pipe 7 is configured (see FIG. 1), one electrolyzed water supply network 8 (open arrow) may be constructed for each of the floors (floors) 1, 2, and 3. In such a configuration, acidic water and alkaline water are alternately supplied along one electrolyzed water supply network 8. Further, two electrolyzed water supply networks 8 may be constructed for one electrolyzed water supply pipe 7. In this case, tanks 5t and 6t for storing acidic water and alkaline water are provided on each floor. Thereby, it becomes possible to supply acidic water and alkaline water to a water intake simultaneously.

  In contrast, when the alkaline water supply pipe and the acidic water supply pipe are configured separately (not shown), an alkaline water supply network that can be connected to the alkaline water supply pipe and an acidic water that can be connected to the acidic water supply pipe. What is necessary is just to build a water supply network separately. In such a configuration, it is possible to supply acidic water and alkaline water simultaneously.

  The electrolyzed water supply network 8 extends while branching from the electrolyzed water supply pipe 7 toward a place (section) where diluted electrolyzed water (acidic water, alkaline water) is utilized. Here, the utilization place (section) may be provided with three intakes (not shown) of acidic water, alkaline water, and tap water. Thereby, the target water (acid water, alkaline water, tap water) can be efficiently and selectively taken in definitely.

  On the other hand, when providing one intake port in the utilization place (section), a tap water faucet (not shown) capable of discharging tap water may be applied as it is. In this case, a switching mechanism (not shown) is connected between the tap water pipe and the tap water faucet. The electrolyzed water supply network 8 is connected to the switching mechanism. In such a configuration, the switching mechanism is controlled. Thereby, it becomes possible to switch to either discharging tap water from the tap water tap or discharging diluted electrolytic water (acidic water, alkaline water) from the tap water tap.

"Low-rise floor 1: shared facilities"
On the lower floor 1, for example, shared facilities such as an elevator 1a, an elevator hall (entrance) 1b, and a pet foot washing place 1c are partitioned.

  The “elevator 1a” repeats the raising and lowering operation. For this reason, it is preferable to apply the water intake (not shown) which can respond to the raising / lowering operation of the elevator 1a. For example, the electrolyzed water supply pipe 7 is configured in a flexible hose shape. Alternatively, instead of such a water intake, for example, a diluted electrolytic water (acid water, alkaline water) tank (not shown) is set in the elevator 1a. Then, the diluted electrolyzed water is sprayed from the tank into the elevator 1a, for example, in a mist form. The timing of spraying is preferably set after confirming that there is no passenger, for example, by a human sensor (not shown) installed in the elevator 1a.

  Moreover, when the tank becomes empty, for example, the diluted electrolyzed water may be automatically poured from the stopped levels (floors) 1, 2, and 3. Further, an electrolyzed water spray mechanism (not shown) is provided for each level (floor) 1, 2, and 3. Then, the diluted electrolyzed water is sprayed into the elevator 1a from the electrolyzed water spray mechanism in synchronization with the stop timing of the elevator 1a. About the frequency | count and time of spraying, it can set freely.

  Furthermore, it is preferable to provide a system (not shown) for spraying diluted electrolyzed water in the elevator hall (entrance) 1b. In this case, it is preferable to set the spraying timing based on, for example, the output of a human sensor (not shown) attached to the elevator hall (entrance) 1b. For example, after confirming that there is no traffic, diluted electrolyzed water is sprayed.

  In the “pet foot washing place 1c”, a tap water faucet (not shown) capable of discharging tap water may be applied as it is as a water intake. In this case, a switching mechanism (not shown) is connected between the tap water pipe and the tap water faucet. If it does so, it can switch to either discharging a tap water from a tap water tap, or discharging diluted electrolyzed water (acidic water, alkaline water) from a tap water tap by a switching mechanism. For example, mud and dust are washed away with tap water. Next, it is sterilized with acidic water. And it wash | cleans with alkaline water.

"Middle floor 2: Housing facilities"
On the middle floor 2, for example, housing facilities such as a kitchen 2a and a bathroom 2b are partitioned.

  “Kitchen 2a” has a relatively high frequency of use of tap water. For this reason, it is preferable to provide a water intake (not shown) capable of discharging diluted electrolyzed water (acidic water, alkaline water) separately from the tap water faucet (not shown). In this case, when the work in the kitchen 2a is finished, for example, after washing with alkaline water, the bacteria are sterilized with acidic water. Thereby, a kitchen can always be maintained in the state cleaned.

  The “bathroom 2b” is preferably provided with a water intake (not shown) and a system (not shown) for spraying diluted electrolyzed water (acidic water, alkaline water) in a mist form. By spraying diluted electrolyzed water in the form of a mist, it is possible to achieve cosmetic use for bathers and use for preventing mold in the bathroom. On the other hand, the diluted electrolyzed water taken from the water intake may be used for sterilization and washing in the bathroom. Moreover, you may utilize diluted electrolyzed water for bathing. For example, mix diluted acidic water with hot water. Thereby, the disinfection thru | or disinfection effect with respect to the area | region ranging from a bathtub to a drain outlet can be expected. Furthermore, it is preferable to enable selection of tap water and diluted electrolyzed water only by the user's panel operation.

"Top floor 3: dedicated equipment"
On the top floor 3, for example, dedicated facilities such as a pool 3a and a rest room 3b are partitioned.

  In the “pool 3a”, it is preferable to construct a system (not shown) that can select tap water or diluted electrolyzed water (acidic water, alkaline water). For example, at the time of cleaning the pool 3a, after washing away dirt with tap water, diluted electrolyzed water is poured. Thereby, the area | region ranging from the pool 3a to a drain port (not shown) can be sterilized and cleaned at a time. Thereafter, diluted electrolyzed water is sprayed in a mist form. Thereby, sterilization of the whole facility of the pool 3a or mold prevention can be aimed at.

  The “rest room 3b” provided with a toilet and a washroom (not shown) has a relatively high frequency of using tap water. For this reason, it is preferable to provide a water intake (not shown) capable of discharging diluted electrolyzed water (acidic water, alkaline water) separately from the tap water faucet (not shown). In particular, the toilet is preferably provided with a water intake capable of selectively flowing tap water and diluted electrolyzed water. For example, tap water is poured on a daily basis, and diluted acidic water is poured at a fixed timing. Thereby, the sterilization of a toilet, cleaning, and a deodorizing (deodorizing) effect can be expected. Moreover, you may flow diluted acid water on a daily basis.

"Operation example of one embodiment"
An example of the operation of the electrolyzed water supply system will be described with reference to the flowcharts of FIGS. 3 to 4 (processes S1 to S8, T1 to T11).

  Electrolyzed water (alkaline water, acidic water) is produced by the electrolyzed water production apparatus 4 (S1 in FIG. 3). The electrolyzed water is diluted to a preset concentration by the electrolyzed water dilution means 5 and 6 (S2 in FIG. 3). Diluted electrolyzed water (alkaline water, acidic water) is supplied to each level (floor) through the electrolyzed water supply pipe 7 (S3 in FIG. 3). And the said diluted electrolyzed water is supplied to the some division constructed | assembled for every hierarchy (floor) by the electrolyzed water supply network 8 (S4 of FIG. 3).

  In this case, when the switching mechanism described above is provided (S5 in FIG. 3), the switching control described above is possible. Further, when a later-described valve mechanism is connected (S6 in FIG. 3), switching control described later becomes possible.

  Here, in the above-described dilution process S2, when a later-described flow monitor 44 is operated (T1 in FIG. 4), the monitor 44 monitors the flow state of various pipes (for example, the electrolytic water supply pipe 7) ( T2 in FIG. That is, it is monitored whether the amount of water is constant (T3 in FIG. 4). Instead, when the capacity monitors 38 and 39 are operated (T4 in FIG. 4), the water amount is similarly monitored (T3 in FIG. 4).

  At this time, it is specified whether the cause that the amount of water cannot be constant is in the alkaline water tank 5t (T5 in FIG. 4) or in the acidic water tank 6t (T6 in FIG. 4). In any case, it is determined whether the amount of water stored in the tanks 5t and 6t is below the water line (T7 in FIG. 4) or above (T8 in FIG. 4).

  And when it is below (T7 of FIG. 4), electrolyzed water (alkaline water, acidic water) is manufactured by the electrolyzed water manufacturing apparatus 4 (T9 of FIG. 4). And it dilutes to the preset density | concentration by the electrolyzed water dilution means 5 and 6 (T10 of FIG. 4). On the other hand, when it exceeds (T8 in FIG. 4). Production of electrolyzed water (alkaline water, acidic water) is stopped (T11 in FIG. 4).

"Effect of one embodiment"
According to the present embodiment, the electrolyzed water production apparatus 4 and the electrolyzed water diluting means 5, 6 are supplied to the hierarchy (floor) 1 for supplying diluted electrolyzed water (acidic water, alkaline water) through the electrolyzed water supply pipe 7. Installed on a level higher than a few (roof floor 10). Thereby, the diluted electrolyzed water can be freely dropped along the electrolyzed water supply pipe 7. By allowing the free fall, for example, the diluted electrolyzed water can flow into the electrolyzed water supply network 8 extending along each floor (floor) without separately providing a water supply mechanism such as a pump. Thus, the diluted electrolyzed water can be supplied without omission over a plurality of sections (for example, shared facilities, residential facilities, and dedicated facilities) in each floor (floor) 1, 2, and 3.

  According to the present embodiment, diluted electrolyzed water (acidic water, alkaline water) is supplied to each floor (floor) 1,2,3. Thereby, for example, even when leakage occurs in the electrolytic water supply pipe 7, the leaked electrolytic water does not adversely affect the surrounding portions.

  According to the present embodiment, the electrolyzed water supply network 8 is extended along the respective layers (floors) 1, 2, and 3 separately from the electrolyzed water supply pipe 7 that allows the diluted electrolyzed water to freely fall. Thereby, the diluted electrolyzed water can be spread without leakage even in a place where the electrolyzed water production apparatus 4 cannot be installed. Thereby, it becomes possible to utilize diluted electrolyzed water for various uses of daily life without omission.

  According to this embodiment, it is a system which makes the diluted electrolyzed water fall freely. Here, for example, assuming a system that pumps diluted electrolyzed water (acidic water, alkaline water), at least two pumps (acidic water pump, alkaline water pump) are required. If so, the configuration of the entire system becomes complicated, and the cost for constructing the system also increases. On the other hand, if it is a system which only makes diluted electrolyzed water fall freely like this embodiment mentioned above, a pump (water supply mechanism) will become unnecessary at all. Thereby, the structure of the whole system can also be simplified. As a result, the cost for constructing the system can be drastically reduced.

  According to the present embodiment, the capacity monitors 38 and 39 are provided in the electrolyzed water dilution means 5 and 6 (the alkaline water tank 5t and the acidic water tank 6t). Thereby, based on the output of the capacity | capacitance monitors 38 and 39, the capacity | capacitance (water storage amount) thru | or density | concentration of the electrolyzed water (alkaline water, acidic water) in each tank 5t, 6t can always be maintained constant. As a result, the target electrolyzed water can be used at any time without omission for various uses in daily life.

"First modification"
Instead of the capacity monitors 38 and 39 described above, for example, a flow monitor 44 may be applied. In this modification, the flow monitor 44 is provided in the above-described electrolyzed water supply pipe 7. When the alkaline water supply pipe and the acidic water supply pipe are configured separately, the flow monitor 44 may be provided in each pipe.

  Specifically, the flow monitor 44 is connected between the electrolyzed water supply pipe 7 and the above-described electrolyzed water supply network 8. Preferably, the flow monitor 44 is connected to the electrolyzed water supply pipe 7 between the electrolyzed water supply network 8 on the top floor and the electrolyzed water dilution means 5 and 6. The electrolysis supply network 8 on the uppermost floor is along the layer (the uppermost floor 3) immediately below the layer (the rooftop floor 10) where the electrolyzed water production apparatus 4 and the electrolyzed water dilution means 5 and 6 are installed. It is extended.

  In this modification, the flow monitor 44 monitors the flow state of diluted electrolyzed water (acidic water, alkaline water) flowing out from the electrolyzed water diluting means (alkaline water diluting means 5, acidic water diluting means 6). Here, the flow state is a concept including, for example, a flow rate or a flow rate per unit time. According to this configuration, the above-described water supply control device 9 controls the electrolyzed water production device 4 based on the output of the flow monitor 44. Thereby, diluted electrolyzed water can be manufactured automatically.

"Second modification"
You may connect a tap water piping (not shown) with respect to the above-mentioned electrolyzed water manufacturing apparatus 4 and the electrolyzed water dilution means 5 and 6, respectively. That is, the electrolyzed water production apparatus 4 and the electrolyzed water dilution means 5 and 6 are connected to the tap water pipe via a valve mechanism (not shown). The valve mechanism is controlled to be opened and closed by, for example, the water supply control device 9 described above.

  In this modification, by controlling the opening and closing of the valve mechanism, flowing electrolytic water from the electrolytic water production apparatus 4 to the tap water pipe, flowing electrolytic water from the electrolytic water diluting means 5 and 6 to the tap water pipe, It is possible to switch to either flowing tap water through the tap water pipe. According to such a configuration, it is possible to flow electrolytic water having a relatively high concentration from the electrolyzed water production apparatus 4 to the tap water pipe. Thereby, the inside of tap water piping can be sterilized and washed, and the drain pipe into which the electrolytic water flows can be sterilized and washed reliably.

“Third Modification”
As an application range of the above-described electrolyzed water supply system, for example, home appliances in which electrolyzed water is likely to be used in the future can be included. Although not particularly illustrated as home appliances, for example, a washing machine, an air conditioner, an air purifier, and the like can be assumed.
