The discharge pipe 17 is formed as a flexible hose made of a resin material having sufficient corrosion resistance against strong acidic water and strong alkaline water. The discharge conduit 17 discharges the strongly alkaline electrolyzed water supplied from the first supply port 11 through the outflow port 16C of the three-way valve 16 to the outside of the casing 5 without mixing with the strongly acidic electrolyzed water. Therefore, the tip end side is connected to the first outlet 14 in the casing 5.

  A mixing pipe 18 is connected to the outflow port 16D of the three-way valve 16 and is provided in the casing 5. Most of the mixing line 18 is formed by using a flexible hose, like the discharge line 17. The mixing pipe 18 is connected to the flow pipe 13 of the strongly acidic electrolyzed water in the casing 5 in order to mix the strongly alkaline electrolyzed water with the strongly acidic electrolyzed water. The mixing line 18 circulates the strongly alkaline electrolyzed water flowing through the inside so as to collide against the strongly acidic electrolyzed water in the flow line 13, thereby mixing the two electrolyzed waters with each other.

  In particular, as shown in FIG. 4, the front end portion 18 </ b> A of the mixing pipe line 18 is located in front of and behind the front end part 13 </ b> A of the flow pipe 13 and the casing 5 across the upper end side (inflow side) of the second discharge port 15. It is arranged so as to face horizontally in the direction. For this reason, the strongly alkaline electrolyzed water in the mixing line 18 and the strongly acidic electrolyzed water in the flow line 13 are mixed so as to collide head-on, and the two are uniformly mixed in the casing from the second outlet 15. 5 is discharged outside.

  Reference numeral 19 denotes a needle valve as a flow rate adjustment valve provided in the casing 5 in the middle of the mixing pipe 18. This needle valve 19 adjusts the mixing ratio of strongly alkaline electrolyzed water and strongly acidic electrolyzed water by variably adjusting the flow rate of strongly alkaline electrolyzed water flowing through the mixing pipe 18 through the three-way valve 16. It is.

  The needle valve 19 is mounted and attached to the base plate 6 with the operation portion 19A for flow rate adjustment facing downward, and is installed at a height position substantially equal to the three-way valve 16 in the casing 5. The operation portion 19A of the needle valve 19 protrudes downward to the outside of the casing 5 through the through hole 6E of the base plate 6, and is disposed at a position operable from the outside. In other words, the needle valve 19 is disposed so that the operation part 19A for flow rate adjustment can be operated from the outside of the casing 5 at a position different from the operation part 16A of the three-way valve 16.

  Reference numeral 20 denotes a branch pipe provided in the casing 5 by branching from the mixing pipe 18 on the upstream side of the needle valve 19. The diversion pipe 20 is branched from an intermediate portion of the mixing pipe 18 using a T-shaped joint 21 called cheese. The diversion pipe 20 is a pipe that diverts a part of the strongly alkaline electrolyzed water guided to the mixing pipe 18 through the three-way valve 16 toward the downstream side of the discharge pipe 17 on the upstream side of the needle valve 19. . The front end side of the diversion pipe 20 is connected to the discharge pipe 17 at the position of the connecting portion 22. This connection part 22 is comprised, for example using a T-shaped coupling member etc., and is installed in the upper position of the 1st discharge port 14, as shown in FIG. Most of the diversion pipe 20 is formed by using a flexible hose, like the discharge pipe 17.

  Reference numeral 23 is a check valve provided in the middle of the diversion pipe 20, and the check valve 23 allows the strong alkaline electrolyzed water to flow from the diversion pipe 20 toward the discharge pipe 17 (connecting portion 22). Is provided between the flow dividing line 20 and the discharge line 17 in order to prevent the reverse flow. That is, the check valve 23 prevents the strong alkaline electrolyzed water flowing through the discharge pipe 17 from flowing in (reverse flow) into the diversion pipe 20.

  Reference numeral 24 denotes an orifice provided in the branch flow line 20 on the upstream side of the check valve 23. The orifice 24 is disposed between the T-shaped joint 21 and the check valve 23, and the mixing line 18. The flow is throttled by imparting resistance to the strongly alkaline electrolyzed water that flows in a branched manner to the branch pipe 20. For this reason, the strongly alkaline electrolyzed water flowing in the mixing pipe line 18 is preferentially supplied to the tip end portion 18A (downstream side) via the needle valve 19, and the strongly alkaline electrolyzed water that has become surplus on the upstream side of the needle valve 19. Only water will be introduced into the diversion conduit 20.

  As shown in FIG. 3, the check valve 23 and the orifice 24 provided in the middle of the diversion pipe 20 are arranged in a position higher than the three-way valve 16 and the needle valve 19 in the casing 5. That is, the check valve 23 and the orifice 24 are disposed at a position higher than the connection portion 22 as a joint that connects the distal end side of the flow dividing pipe 20 to the discharge pipe 17. Therefore, it is arranged at a position higher than the three-way valve 16 and the needle valve 19.

An inflow port 16 </ b> B of a three-way valve 16 is connected to the first supply port 11 through a supply line 11 </ b> A in the casing 5. Then, the three-way valve 16 manually operates the operation portion 16A such as an operation lever from the outside of the casing 5, thereby causing strong alkaline electrolyzed water from the first supply port 11 to flow between the discharge conduit 17 and the mixing conduit 18. Selectively distribute to either one.

  When strong alkaline electrolyzed water is circulated to the discharge pipe 17 side by the selection operation of the three-way valve 16, the strong alkaline electrolyzed water guided from the first supply port 11 into the casing 5 is used as it is in the PH concentration ( For example, it can be discharged out of the casing 5 from the first outlet 14 at PH 12.5). This strong alkaline electrolyzed water is suitably used for cleaning of therapeutic instruments, in-hospital cleaning, and the like in, for example, dental clinics and hospitals. In golf courses, farms, etc., it is used as spray water for the purpose of promoting the growth of plants.

  On the other hand, the strongly acidic electrolyzed water guided from the second supply port 11 into the casing 5 through the flow conduit 13 has the same PH concentration (for example, PH 1.9 to 2.5) as the second discharge port. 15 can be discharged out of the casing 5. This strongly acidic electrolyzed water is used, for example, for sterilization of oral wounds and sterilization of therapeutic instruments in dental clinics. In golf courses, farms, etc., strong acidic electrolyzed water can be sprayed for the purpose of controlling pathogens, viruses, and diseases.

  Next, when the operation portion 16A of the three-way valve 16 is operated from the outside of the casing 5 and the inflow port 16B of the three-way valve 16 is connected to the other outflow port 16D, the first supply port 11 is supplied. Strong alkaline electrolyzed water is circulated toward the mixing pipe 18 and can be led to the position of the needle valve 19. By manually operating the operation portion 19A of the needle valve 19 from the outside of the casing 5, the flow rate of the strong alkaline electrolyzed water flowing to the tip end portion 18A side of the mixing pipe line 18 can be appropriately adjusted.

  On the base plate 6 of the casing 5, by forming an identification display such as a scale around the through hole 6E (see FIG. 5), it is determined how much the operation portion 19A of the needle valve 19 is rotated. It can be adjusted while judging from the outside of the casing 5 (base plate 6). When the flow rate of the strongly alkaline electrolyzed water guided to the upstream side of the needle valve 19 through the mixing pipe 18 is Q and the adjustment ratio k (for example, 0.1 ≦ k ≦ 1.0), the adjusted flow rate (k × The strongly alkaline electrolyzed water of Q) is supplied to the downstream side of the needle valve 19 (the front end portion 18A of the mixing pipe line 18).

  At this time, strong alkaline electrolyzed water corresponding to the remaining flow rate [(1-k) × Q] becomes surplus water and is diverted to the diversion pipe line 20 side via the T-shaped joint 21. The orifice 24 provided in the middle of the diversion pipe 20 gives a throttling action to the strongly alkaline electrolyzed water that has become surplus on the upstream side of the needle valve 19. For this reason, among the strong alkaline electrolyzed water having a flow rate Q flowing through the mixing pipe 18, the strong alkaline electrolyzed water for the adjusted flow rate (k × Q) is preferentially given to the tip 18 </ b> A (downstream side) via the needle valve 19. Therefore, only strong alkaline electrolyzed water corresponding to the remaining flow rate [(1−k) × Q] that is surplus on the upstream side of the needle valve 19 can be guided to the diversion pipe 20. .

  Excess water of strong alkaline electrolyzed water guided to the diversion pipe 20 flows from the connecting portion 22 to the discharge pipe 17 via the check valve 23 and is discharged from the first discharge port 14. At this time, the check valve 23 prevents the strong alkaline electrolyzed water flowing through the discharge pipe 17 from flowing back (inflow) into the diversion pipe 20. On the other hand, the strongly alkaline electrolyzed water for the adjusted flow rate (k × Q) flowing in the mixing pipe 18 toward the tip end 18A (downstream) collides with the strongly acidic electrolyzed water in the flow pipe 13. Mixed. Thereby, from the 2nd discharge port 15, the mixed water which mixed two electrolyzed water mutually, ie, the mixed water by which PH density | concentration was adjusted, can be discharged | emitted.

  In particular, according to the first embodiment, as shown in FIG. 4, the tip end 18 </ b> A of the mixing pipe 18 is located on the upper end side (inflow side) of the second discharge port 15. The front end portion 13A and the casing 5 are disposed so as to be horizontally opposed in the front and rear directions. For this reason, the strongly alkaline electrolyzed water in the mixing line 18 and the strongly acidic electrolyzed water in the flow line 13 can be mixed so as to collide front, and the mixed water whose PH concentration is uniformly adjusted is the second. Can be discharged out of the casing 5.

  At this time, the PH concentration can be adjusted as appropriate by rotating the operation portion 19 </ b> A of the needle valve 19 from the outside of the casing 5. That is, if the valve opening of the needle valve 19 is increased and the adjustment flow rate (k × Q) of the strongly alkaline electrolyzed water is increased, the mixing ratio of the strongly alkaline electrolyzed water to the strongly acidic electrolyzed water in the flow conduit 13 is increased. For example, alkaline mixed water having a concentration of about PH 9.5 can be taken out from the second outlet 15 so as to be discharged out of the casing 5.

  On the other hand, the adjustment flow rate (k × Q) of the strongly alkaline electrolyzed water is reduced so that the valve opening degree of the needle valve 19 is reduced, that is, the adjustment ratio k (0.1 ≦ k ≦ 1.0) is reduced. If the operation unit 19A is rotated, the mixing ratio of the strongly alkaline electrolyzed water to the strongly acidic electrolyzed water in the flow conduit 13 can be lowered. For example, acidic mixed water having a concentration of about PH 3 to 4 2 can be taken out from the casing 5 so as to be discharged out of the casing 5. In this case, the concentration can be adjusted by, for example, 0.1 unit of PH concentration. Usually, the PH concentration (mixing ratio) of the mixed water is adjusted with an adjustment margin of, for example, about 0.2 unit with respect to the target concentration. You can adjust.

  That is, if the flow ratio of strong alkaline electrolyzed water to strong acidic electrolyzed water is approximately 1: 1, neutral or near-neutral mixed water having a pH of 6.3 to 7.0 can be prepared. By gradually increasing the flow rate ratio, for example, alkaline mixed water having a pH of 7.2 or higher can be prepared. On the other hand, by gradually lowering the flow ratio of strongly alkaline electrolyzed water to strongly acidic electrolyzed water from 1: 1, acidic mixed water having a pH of 6.3 to 6.8 or less can be prepared, for example.

  Table 1 below shows the relationship between the PH concentration and the effective chlorine concentration when strongly alkaline electrolyzed water (raw liquid) is mixed with strongly acidic electrolyzed water (raw water). Here, the strongly acidic electrolyzed water has a pH of 1.9 and an effective chlorine concentration of 96 ppm. Strong alkaline electrolyzed water has a pH of 12.5 and an effective chlorine concentration of 0 ppm. On the other hand, Table 2 below shows the relationship between the PH concentration and the effective chlorine concentration when tap water (mixed solution) is mixed with strongly acidic electrolyzed water (raw water). Also in this case, the strongly acidic electrolyzed water has a pH of 1.9 and an effective chlorine concentration of 96 ppm, and the tap water has a pH of 6.8 and an effective chlorine concentration of 0 ppm.

  As is clear from Tables 1 and 2 above, in order to adjust (control) the PH concentration of strongly acidic electrolyzed water, when mixing with tap water by mixing using strongly alkaline electrolyzed water as a mixed solution It is confirmed that the PH concentration can be easily adjusted as compared with FIG. In addition, when compared at the same PH concentration (for example, PH 2.3), the effective chlorine concentration is 1.67 when the strongly alkaline electrolyzed water is used as the mixed solution compared with the one using tap water. Since the double concentration can be maintained, neutralized water that maintains the bactericidal effect can be easily produced.

  Thus, according to the first embodiment, strong alkaline electrolyzed water supplied from the electrolyzed water generating device 1 into the casing 5 of the mixing device 4 is selected as one of the discharge pipe 17 and the mixing pipe 18. Therefore, the operation portion 16A of the three-way valve 16 can be easily operated from the outside of the casing 5, and the flow direction of the strongly alkaline electrolyzed water can be easily selected.

  When the strong alkaline electrolyzed water is circulated in the mixing pipe line 18, the flow rate of the strong alkaline electrolyzed water is controlled by operating a needle valve 19 provided in the middle of the mixing pipe line 18 from the outside of the casing 5. It can be adjusted variably, and the mixing ratio of the strongly alkaline electrolyzed water and the strongly acidic electrolyzed water can be easily adjusted.

  Therefore, when adjusting the PH concentration of the mixed water, the mixing ratio of the strongly alkaline electrolyzed water and the strongly acidic electrolyzed water is variably adjusted by operating the three-way valve 16 and the needle valve 19 from the outside of the casing 5. For example, gargle water for sterilization of oral cavity in dental clinics can be prepared so as to be within the quality standards of tap water, and mixed gargle that retains the sterilization power of acidic water It can be provided easily and conveniently as water. In addition, for sprayed water used in farms, golf courses, etc., by controlling pH concentration by mixing strongly acidic electrolyzed water with strong alkaline electrolyzed water, it is possible to control diseases while suppressing discoloration of planting due to acid burning. It can be performed.

  Further, according to the first embodiment, the first and second supply ports 11 and 12, the first and second discharge ports 14 and 15, the three-way valve 16, the strong alkaline electrolyzed water discharge conduit 17, Mixing line 18 of strong alkaline electrolyzed water for strongly acidic electrolyzed water, needle valve 19 provided in the middle of mixing pipe 18, a part of strong alkaline electrolyzed water discharged from mixing pipe 18 upstream of needle valve 19 The diversion pipe 20 for diverting to the path 17 side, the check valve 23 and the orifice 24 provided in the middle of the diversion pipe 20 can be accommodated in the casing 5 in a compact manner, and the entire mixing device 4 can be arranged. The maintainability can be improved by downsizing.

  Then, by arranging the check valve 23 and the orifice 24 at a higher position in the casing 5 than the needle valve 19 and the three-way valve 16, hydrogen bubbles mixed in the strongly alkaline electrolyzed water are distributed along the branch flow line 20. It can escape to the upper position of the casing 5. Thereby, the flow rate adjustment by the needle valve 19 can be stabilized, the mixing property of the strongly alkaline electrolyzed water with respect to the strongly acidic electrolyzed water can be enhanced, and the concentration of the entire mixed water can be made uniform.

  Moreover, the orifice provided in the middle of the diversion pipe 20 restricts the flow rate of the strong alkaline electrolyzed water flowing from the mixing pipe 18 toward the diversion pipe 20 and gives flow resistance, thereby adjusting the flow rate at the needle valve 19. The adjustment work can be facilitated and stabilized while expanding the range. As a result, the mixed water having the necessary concentration corresponding to the flow rate adjustment at the needle valve 19 can be taken out from the second discharge port 15 with the PH concentration of the mixed water adjusted appropriately.

  Furthermore, according to the first embodiment, the casing 5 of the mixing device 4 is constituted by the base plate 6 and the outer case 7, and the base plate 6 has the first and second supply ports 11, 12, and the circulation.
