Description

  The present invention relates to an electrolyzed water generating device that generates electrolyzed water by electrolyzing water.

  2. Description of the Related Art Conventionally, an electrolyzed water generating apparatus is known that electrolyzes water to generate electrolyzed reduced water (hereinafter referred to as “electrolytic hydrogen water”) and electrolytic acid water. For example, an electrolyzed water generator disclosed in Patent Document 1 below includes an electrolyzer provided with a cathode chamber and an anode chamber separated by a diaphragm (separator), and electrolyzes water in the electrolyzer. Electrolytic hydrogen water is obtained from the cathode chamber, and electrolytic acid water is obtained from the anode chamber. This diaphragm is comprised with the sheet | seat material which has ion permeability, and prevents mixing of the water ionized by the electrolytic hydrogen water and the electrolytic acidic water. In addition, in this electrolyzed water generator, in order to clean the so-called “scale” (metal ions such as calcium contained in water) adhering to the electrodes, the polarity of the electrodes in the anode chamber and the cathode chamber is changed after a certain period of time. Inverting technology is adopted.

  By the way, in the electrolyzed water generating apparatus, not only generating electrolyzed hydrogen water and electrolyzed acidic water, but also producing electrolyzed mixed water by mixing electrolyzed hydrogen water and electrolyzed acidic water is known. For example, in the electrolyzed water generating device disclosed in Patent Document 2 below, electrolyzed hydrogen water and electrolyzed acidic water are joined together by a valve device provided at a downstream position of the electrolyzer to produce electrolyzed mixed water. To the outside. According to this electrolyzed water generating apparatus, since not only electrolyzed hydrogen water and electrolyzed acidic water but also electrolyzed mixed water can be generated, electrolyzed water corresponding to various needs can be obtained.

Japanese Patent No. 2618321 JP 2001-246383 A

  By the way, as in the electrolyzed water generating device described in Patent Document 2, when the acidic acid water and the electrolyzed hydrogen water are simply joined at a predetermined ratio at the downstream position of the electrolytic cell, the pressure is applied to the diaphragm in the electrolytic cell. May be applied. This is because when acidic electrolytic water and electrolytic hydrogen water are merged at a predetermined ratio at the downstream position of the electrolytic cell, the pressure (back pressure) on the flow path side with a small flow rate is affected by the pressure on the flow path side with a large flow rate due to the merge. This is because this pressure change (pressure difference) gives a load to the diaphragm in the electrolytic cell.

  When the pressure changes as described above, the diaphragm is composed of a thin sheet material having ion permeability as described above, and thus the sheet material may be damaged. As a result, in the worst case, the problem arises that the expensive electrolytic cell must be replaced.

  Therefore, the present invention has been made to solve the above problems, and while using the electrolytic water generating device to generate electrolytic mixed water, it reduces the burden on the diaphragm of the electrolytic cell and uses the electrolytic cell for a long period of time. It is an object of the present invention to provide an electrolyzed water generating device that can be used.

  The electrolyzed water generating device of the present invention is an electrolyzed water generating device comprising an electrolytic cell in which a cathode chamber and an anode chamber are separated by a diaphragm, and a predetermined merging ratio of electrolytic acid water in the anode chamber and electrolytic hydrogen water in the cathode chamber When the electrolyzed mixed water is generated by merging in the above, the diversion ratio of the raw water to the anode chamber and the cathode chamber is made to coincide with the predetermined merging ratio of the electrolytic acid water and the electrolytic hydrogen water. Is.

  Specifically, the first invention includes a first chamber including a first electrode serving as a positive electrode, a second chamber including a second electrode serving as a cathode, and a diaphragm partitioning the first chamber and the second chamber. An electrolyzed water generating device comprising: an electrolyzer equipped with an inside; a raw water supply water channel for supplying raw water to the electrolyzer from outside; and an electrolyzed water discharge channel for discharging electrolyzed water generated in the electrolyzer to the outside. A first flow path valve provided in the raw water supply channel, a second flow path valve provided in the electrolyzed water discharge channel, and operating the second flow channel valve with a predetermined control signal, The acidic acidic water generated in the first chamber using the first electrode as a positive electrode and the electrolytic hydrogen water generated in the second chamber using the second electrode as a cathode are merged at a predetermined merging ratio. , A merging operation means for generating electrolytic mixed water, and the first flow path valve in synchronism with the operation of the second flow path valve By actuating, the flow rate to the first chamber and the diversion ratio of the flow rate to the second chamber are matched with the predetermined merging ratio of the second flow path valve, and the raw water is mixed with the first chamber and the first chamber. An electrolyzed water generating device comprising a diversion operating means for diverting to a second chamber.

  According to the above configuration, the first flow path valve is provided upstream of the electrolytic cell, the second flow path valve is provided downstream of the electrolytic cell, and when the electrolytic mixed water is generated, the second flow path valve is formed by the merging operation means. , The acidic acidic water and the electrolytic hydrogen water are merged at a predetermined merging ratio, and the first flow path valve is operated by the divergence operating means, so that the raw water is fed to the first chamber and the second at a predetermined divergence ratio. Shunt to room. At this time, the raw water is divided by matching a predetermined diversion ratio in the first flow path valve with a predetermined merge ratio in the second flow path valve.

  For this reason, even when the electrolytic acid water and the electrolytic hydrogen water are merged downstream of the electrolytic cell when the electrolytic mixed water is generated, the raw water has a diversion ratio that matches the merge ratio at the upstream position of the electrolytic cell. Since the flow is divided into the first chamber and the second chamber, no pressure change occurs in the first chamber and the second chamber, and no load is generated on the diaphragm.

  According to a second aspect of the present invention, there is provided the electrolysis apparatus according to the first aspect, further comprising electrode inversion control means for inverting the polarity of the first electrode and the polarity of the second electrode every elapse of a predetermined time. It is a water generator.

  According to the above configuration, the polarity of the first electrode and the polarity of the second electrode are reversed by the electrode inversion control means after a predetermined time has elapsed. For this reason, the scale adhering to the electrode can be washed. Therefore, the electrolysis power of the electrolytic cell can be maintained for a long time.

  Moreover, since the ion movement direction is reversed by reversing the polarity of the electrodes with respect to the diaphragm, there is no bias in the movement of ions, and the burden on the diaphragm can be reduced.

  Therefore, the life of the electrode can be extended, and the performance of the diaphragm can be maintained for a long time.

  However, by reversing the polarity of the electrodes, the polarity of the first chamber and the polarity of the second chamber are reversed, and the generation location of the electrolytic acid water and the generation location of the electrolytic hydrogen water are reversed. Since both are merged by the flow path valve and the same electrolytic mixed water is finally generated, there is no problem in terms of discharging the electrolytic mixed water.

  Therefore, according to the second invention, it is possible to reliably obtain the electrolytic mixed water while stably suppressing the burden on the electrolytic cell for a long period of time.

  In addition, the third invention is the first invention or the second invention, wherein the power supply to the first electrode and the second electrode is stopped and the raw water is controlled to flow in the electrolytic cell as it is. An electrolyzed water generating device comprising an electrode stop control means.

  According to the above configuration, the power supply to the first electrode and the second electrode is stopped, and the raw water flows into the electrolytic cell as it is, so that the raw water is discharged as it is, not the electrolytic mixed water, from the electrolytic water drain. Will be.

  Therefore, according to the present invention, raw water can be obtained in addition to the electrolytically mixed water. If a water purifier is installed in the middle of the water channel, purified water can be obtained in addition to the electrolytically mixed water. And since raw | natural water flows in an electrolytic cell as it is, since the diaphragm, an electrode, etc. of an electrolytic vessel can be wash | cleaned with raw | natural water, the lifetime of a diaphragm etc. can be made longer.

  Therefore, according to the third invention, raw water and the like can be obtained from the electrolytic water discharge port in addition to the electrolytic mixed water. Moreover, the lifetime of a diaphragm, an electrode, etc. can be lengthened.

  Moreover, 4th invention is the invention in any one of 1st invention thru | or 3rd invention, The said raw | natural water supply water channel is comprised by the 1st raw | natural water supply water channel and the 2nd raw water supply water channel, The said electrolyzed water The drainage channel is composed of a first electrolyzed water drainage channel and a second electrolyzed water drainage channel, and the first channel valve is connected to the first raw water supply channel and the raw water flows to the first chamber. A passage and a second passage connected to the second raw water supply water channel and flowing raw water to the second chamber are provided, and the second flow path valve is connected to the first chamber and connected to the first electrolysis When a predetermined condition is detected, a third passage through which the electrolytic water flows into the water drainage channel and a fourth passage through which the electrolytic water flows to the second electrolytic water drainage passage are connected to the second chamber. Comprises second electrode inversion control means for inverting the polarity of the first electrode and the polarity of the second electrode. When the polarity of the electrode is reversed by the second electrode inversion control means, the third passage and the fourth passage of the second passage valve are switched, and the first passage of the first passage valve is switched. An electrolyzed water generating device characterized in that a flow path switching means for switching the flow path of the second passage is provided.

  According to the above configuration, the raw water supply channel is composed of the first raw water supply channel and the second raw water supply channel, the raw water is supplied from the two supply channels, and the electrolyzed water drain channel is connected to the first electrolyzed water channel. It comprises a 2nd electrolyzed water drainage channel, and electrolyzed water is discharged | emitted from two discharge water channels. Then, from these two supply channels, the raw water is poured into the first chamber and the second chamber by the first passage and the second passage of the first flow path valve, respectively, and the electrolyzed water from the first chamber and the second chamber is poured. The third passage and the fourth passage of the second passage valve discharge from these two drainage channels.

  When the second electrode inversion control means reverses the polarity of the first electrode and the polarity of the second electrode, the first electrolysis is performed to switch the third passage and the fourth passage of the second passage valve. Neither the electrolyzed water discharged from the water drainage channel nor the electrolyzed water discharged from the second electrolyzed water drainage channel has the same polarity (the electrolyzed water discharged from each drainage channel does not change).

  At the same time, since the first passage and the second passage of the first flow path valve are also switched, the ratio of the electrolytic water flowing out from the first chamber and the second chamber of the electrolytic cell before and after the electrode inversion is reduced. The ratio of raw water flowing into the first chamber and the second chamber of the tank can be made the same. For this reason, a burden is not given to the diaphragm in an electrolytic cell.

  Therefore, according to the fourth aspect of the invention, even if the polarity of the electrode is reversed, the polarity of the electrolyzed water discharged from the first electrolyzed water drainage channel and the second electrolyzed water drainage channel does not change. In addition to the electrolytically mixed water, electrolytic hydrogen water and electrolytic acid water can be obtained with certainty. Moreover, since the burden is not given with respect to a diaphragm, the lifetime of a diaphragm can be lengthened further.

  According to the present invention, when the electrolytic mixed water is generated, even if the electrolytic acid water and the electrolytic hydrogen water are combined at the downstream position of the electrolytic cell, the raw water is the same ratio as the combined ratio at the upstream position of the electrolytic cell. Therefore, the pressure is not changed between the first chamber and the second chamber, and no load is generated on the diaphragm.

  Therefore, the electrolytic cell can be used for a long time while reducing the burden on the diaphragm of the electrolytic cell while generating the electrolytic mixed water with the electrolytic water generating device.

Yes. In this way, the electrolyzed water discharge channel O is configured.

  Next, the above-described double cross line valve 1 will be described in detail with reference to FIG. FIG. 2 is an exploded perspective view of the double cross line valve 1.

  The double crossline valve 1 includes a cylindrical outer cylinder 11 and a cylindrical inner cylinder 20 that fits into the outer cylinder 11, and the inner cylinder 20 is fitted into the outer cylinder 11. In this state, the inner cylindrical body 20 is rotated around the A axis to change the relative angle between the inner cylindrical body 20 and the outer cylindrical body 11, so that the flow path of the internal water is switched appropriately. Has been. Thereby, the double cross line valve 1 functions as the first flow path valve and the second flow path valve of the present invention.

  In this embodiment, the single flow path valve and the second flow path valve are configured by one double cross line valve 1, but of course, the first flow path valve and the second flow path are separated by separate valves. A valve may be configured.

  The aforementioned outer cylinder 11 is formed in a bottomed cylindrical shape in which the right end surface of the outer cylinder 11 shown in FIG. 2 is a sealed bottom surface 12 and the inside is hollow, and an angle of 90 ° in the direction orthogonal to the A axis ( In FIG. 2, a total of eight openings 13a, 13b, 14a, 14b, 15a, 15b, 16a, 16b are provided, each having four openings arranged in a straight line so as to form an angle α).

A second inlet 13b to which the water channel 4b is connected, a second re-outlet 14b to which the second drainage channel 8b is connected, and a first re-outlet 14a to which the first drainage channel 8a is connected, from the right side to the left side. In order. Of these, only the first re-outlet 14a has a connector shape.

  The openings 15a, 15b, 16a and 16b are connected to the first outlet 15a connected to the first electrode chamber Da and the second electrode chamber Db at a position above the outer cylinder 11 shown in FIG. The second outlet 15b, the second reinlet 16b to which the second take-out water channel 7b is connected, and the first re-inlet 16a to which the first take-out water channel 7a is connected are provided in order from the right side to the left side. It has been.

  The aforementioned inner cylinder 20 is formed in a double-bottom cylindrical shape in which both end surfaces (only the right end is shown in FIG. 2) are sealed bottom surfaces 21a and 21b and the interior is hollow. Although not shown in FIG. 2, a partition wall 22 (see FIG. 3) that partitions the internal space in the left-right direction is provided at the axial center position of the inner cylinder 20.

  On the outer periphery of the inner cylinder 20, a plurality of convex portions 23, 24, 25, which are liquid-tightly fitted to the inner peripheral surface 11 a of the outer cylinder 11, at positions corresponding to the openings of the outer cylinder 11. 26 and a portion of the outer peripheral surface 27 of the circular arc curved surface so that a gap is formed between the inner peripheral surface 11a of the outer cylinder 11 and the portion provided with 26.

  The convex portions 23, 24, 25, and 26 are elongated oval-shaped first portions that are provided at about 90 ° or more along the outer circumferential direction of the inner cylinder 20 at the axially central right position of the inner cylinder 20. A first convex portion 23, and a short elliptical second convex portion 24 provided at a position on the right side of the first convex portion 23 and spaced apart from the first convex portion 23 by about 90 ° in the outer circumferential direction of the inner cylindrical body 20. The third convex portion 25 having an elliptical shape provided in the axially central left side position of the inner cylindrical body 20 along the outer circumferential direction of the inner cylindrical body 20 over about 90 °, and the third convex portion 25 A short elliptical fourth convex portion 26 is provided on the left side of the third convex portion 25 so as to be separated from the third convex portion 25 in the outer circumferential direction of the inner cylindrical body 20 by about 90 °.

  Then, the first guide hole 28 and the second guide hole 29 are formed at both end positions in the outer peripheral direction of the first convex portion 23 with an interval of about 90 ° in the outer peripheral direction. The space is configured to communicate with the external space. Further, the second convex portion 24 is also formed with a third guide hole 30 (see FIG. 4) so as to communicate the inner space and the outer space of the inner cylindrical body 20. The fourth guide hole 31 and the fifth guide hole 32 are formed at both end positions in the outer peripheral direction of the third convex portion 25 with an interval of about 90 ° in the outer peripheral direction, so that the inner space of the inner cylindrical body 20 is formed. And communicate with the external space. Further, a sixth guide hole 33 (see FIG. 4) is also formed in the fourth convex portion 26 so as to communicate the internal space and the external space of the inner cylindrical body 20.

  Further, a partition rod part 34 that protrudes outward and is formed in a bowl shape is provided at the axial center position of the inner cylindrical body 20. The partition rod 34 is liquid-tightly fitted to the inner peripheral surface 11a of the outer cylindrical body 11 by an annular rubber material 34a fitted around. This partitioning rod portion 34 prevents water from flowing into the double crossline valve 1 from the left portion 1B to the right portion 1A and from the right portion 1A to the left portion 1B.

  Further, the right and left ends of the inner cylindrical body 20 are provided with sealed flange portions 35 and 36 that project outward and have a bowl shape. In particular, the sealing flange 36 at the left end is liquid-tightly fitted to the inner peripheral surface 11a of the outer cylinder 11 by an annular rubber material 36a fitted around. This prevents water from leaking from the inside of the double cross line valve 1.

  As described above, the double cross line valve 1 is constituted by the partition rod portion 34 of each of the inner cylinders 20, the convex portions 23, 24, 25, 26, the guide holes 28, 29, 30, 31, 32, 33, and the like. By defining the flow of water inside the double cross line valve 1, it functions as the first flow path valve or the second flow path valve of the present invention.

  Specifically, the flow of water is freely switched by rotating the inner cylinder 20 by the power of the double crossline valve motor m2 via the rotary boss shaft 37 provided at the left end of the inner cylinder 20. It is configured.

  Next, the flow path change of the water by the rotation angle of this inner cylinder 20 is demonstrated using FIG. 3 thru | or FIG. 3 shows a case where the rotation angle position of the inner cylinder 20 is 0 °, FIG. 4 shows a case where the rotation angle position of the inner cylinder 20 is 90 °, and FIG. 5 shows a case where the rotation angle position of the inner cylinder 20 is 45 °. Respectively. Hereinafter, “rotational angle position” will be abbreviated as “position”.

  First, as shown in FIGS. 3 (a) and 3 (b), when the position of the inner cylinder 20 is 0 °, as shown by an arrow (a part is indicated by a dotted line in FIG. 3 (b)), The water that has entered from the first inlet 13a of the cylinder 11 has no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that coincides with the position of the first inlet 13a). The liquid flows out from the first outlet 15a of the outer cylinder 11 to the outside (to the electrolytic cell D) through the gap w between the outer peripheral surface 27 and the inner peripheral surface 11a of the outer cylinder 11. On the other hand, the water entering from the second inlet 13b of the outer cylinder 11 passes through the first guide hole 28 because the positions of the first guide hole 28 and the second inlet 13b of the inner cylinder 20 coincide. Then, it flows into the right inner space S1 in the inner cylinder 20. Then, since the water that has flowed in matches the positions of the second guide hole 29 of the inner cylinder 20 and the second outlet 15b, the water passes through the second guide hole 29 and passes through the second outlet 15b to the outside. (Corresponding to the first passage and the second passage of the present invention).

  Further, the water flowing out from the electrolytic cell D enters the left portion 1B of the double crossline valve 1 from the first reinlet 16a and the second reinlet 16b of the outer cylinder 11, but as shown by the arrows, the outer cylinder Since there is no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that coincides with the position of the first re-inlet 16a), the water that has entered from the first first inlet 16a has an outer periphery of the inner cylinder. The air flows out from the first re-outlet 14a of the outer cylinder 11 through the gap w between the surface 27 and the inner peripheral surface 11a of the outer cylinder 11.

  On the other hand, the water that has entered from the second reinlet 16b of the outer cylinder 11 passes through the fourth guide hole 31 because the positions of the fourth guide hole 31 and the second reinlet 16b of the inner cylinder 20 coincide. Then, it flows into the left inner space S2 in the inner cylinder 20. And since this flowed-in water has the position of the 5th guide hole 32 and the 2nd re-outlet 14b of the inner cylinder 20 corresponded, it passes through the 5th guide hole 32, and the outside from the 2nd re-outlet 14b. (Corresponding to the third and fourth passages of the present invention).

  Next, as shown in FIGS. 4 (a) and 4 (b), when the position of the inner cylinder 20 is 90 °, as shown by an arrow (a part is shown by a dotted line in FIG. 4 (b)), The water that has entered the first inlet 13a of the outer cylinder 11 has no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that coincides with the position of the first inlet 13a). Passes through a gap w between the outer peripheral surface 27 of the outer cylinder 11 and the inner peripheral surface 11a of the outer cylinder 11. However, since the second protrusion 24 is present at the first outlet 15a to stop the flow of water, the water that has passed through the gap w is at an oblique position from the first inlet 13a and is open. It flows out from the two outlets 15b to the outside (to the electrolytic cell D).

  On the other hand, the water that has entered the second inlet 13b of the outer cylinder 11 passes through the second guide hole 29 because the positions of the second guide hole 29 and the second inlet 13b of the inner cylinder 20 coincide. Then, it flows into the right inner space S1 in the inner cylinder 20. But since the position of the 3rd guide hole 30 of the inner cylinder 20 and the 1st outflow port 15a corresponds, the water which flowed into the right side inner space S1 passes the 3rd guide hole 30, and the 1st flow of the diagonal position is carried out. It flows out from the outlet 15a to the outside (to the electrolytic cell D). That is, in this case, the flow path of the water “crosses”, and the flow path is reversed and switched from the case where the position of the inner cylinder 20 is 0 ° (the first aspect of the present invention). Corresponds to switching between one passage and second passage).

  Further, when the water flowing out from the electrolytic cell D enters the first reinlet 16a and the second reinlet 16b of the outer cylinder 11, it enters from the first reinlet 16a of the outer cylinder 11 as shown by the arrows. Since the positions of the sixth guide hole 33 and the first re-inlet 16a of the inner cylinder 20 coincide with each other, the water passes through the sixth guide hole 33 and flows into the left inner space S2 in the inner cylinder 20. . And since this flowed-in water has the position of the 4th guide hole 31 of the inner cylinder 20, and the 2nd re-outlet 14b, it passes the 4th guide hole 31 from the left side internal space S2, and the 1st It flows out of the second re-outlet 14b at an oblique position from the re-inlet 16a. On the other hand, the water that has entered the second re-inlet 16b of the outer cylinder 11 has no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that matches the position of the second re-inlet 16b). It passes through a gap w between the outer peripheral surface 27 of the inner cylinder 20 and the inner peripheral surface 11a of the outer cylinder 11. But the position of the 4th guide hole 31 and the 2nd re-outlet 14b is in agreement, and since the water which entered into the 2nd re-inlet 16b cannot flow out from the 2nd re-outlet 14b, the water which passed through crevice w is The second re-inlet 16b is at an oblique position and flows out from the open first re-outlet 14a. That is, even in the left side portion 1B of the double cross line valve 1, when the position of the inner cylinder 20 is 90 °, the flow path of the water “crosses”, and the position of the inner cylinder 20 is The flow path is reversed and switched from the case of 0 ° (corresponding to switching of the third passage and the fourth passage of the present invention).

  Next, as shown in FIG. 5, when the position of the inner cylinder 20 is 45 °, the first inlet of the outer cylinder 11 is indicated by an arrow (a part is indicated by a dotted line in FIG. 5B). Since there is no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that coincides with the position of the first inflow port 13a), the water that has entered 13a does not have the outer peripheral surface 27 of the inner cylinder 20 and the outer cylinder. 11 flows out from the first outflow port 15a and the second outflow port 15b of the outer cylindrical body 11 through a gap w between the inner peripheral surface 11a. At this time, since a part of the second convex portion 24 overlaps the first outlet 15a, the flow rate from the first outlet 15a is somewhat limited, and the splitting ratio between the first outlet 15a and the second outlet 15b is about About 40 to 60, water is diverted and flows out to the outside (electrolysis cell D). On the other hand, since the position of the second inlet 13b coincides with the portion where the holes 28 and 29 of the first convex portion 23 are not formed, the first convex portion is formed in the second inlet 13b of the outer cylindrical body 11. The presence of 23 prevents water from flowing in. For this reason, in the right side portion 1A of the double cross line valve 1, it functions as a diversion valve that diverts only the water flowing in from the first inflow port 13a into the first outflow port 15a and the second outflow port 15b (in the present invention). This corresponds to the shunt flow of the first flow path valve).

  Moreover, although the water which flowed out from the electrolytic cell D enters into the 1st reinlet 16a and the 2nd reinlet 16b of the outer cylinder 11, as shown by the arrow (in FIG.5 (b), a part is shown with a dotted line) The water that has entered from the first re-inlet 16a of the outer cylinder 11 has no hole corresponding to the inner cylinder 20 (that is, the hole of the inner cylinder 20 that coincides with the position of the first re-inlet 16a). The air flows out from the first re-outlet 14a of the outer cylinder 11 through the gap w between the outer peripheral surface 27 of the cylindrical body 20 and the inner peripheral surface 11a of the outer cylindrical body 11. In addition, since the water that has entered from the second re-inlet 16b of the outer cylindrical body 11 is located in the second re-outlet 14b, the portion where the holes 31 and 32 of the third convex portion 25 of the inner cylindrical body 20 are not formed. The air flows out from the first re-outlet 14a through the gap w between the outer peripheral surface 27 of the inner cylindrical body 20 and the inner peripheral surface 11b of the outer cylindrical body 11. For this reason, the left side portion 1B of the double crossline valve 1 also functions as a merging valve for merging the water flowing in from the first reinlet 16a and the second reinlet 16b into the first reoutlet 14a (first of the present invention). This corresponds to the merging of two flow path valves).

  Even in this merging, since the fourth convex portion 26 partially overlaps the first reinlet 16a, the flow rate from the first reinlet 16a is somewhat limited, and the first reinlet 16a and the second reinlet 16b The merge ratio is approximately 40 to 60. This is a ratio that matches the diversion ratio described above, but the reason for this is the size, shape, phase position, etc., of the second convex part 24 and the fourth convex part 26 provided on the inner cylinder 20. This is because the inner cylinder 20 provided with the second convex portion 24 and the fourth convex portion 26 is integrally rotated.

  In addition, since the diversion ratio and the merging ratio of the double cross line valve 1 are made the same as described above, the pressure in the electrolytic cell D and the like do not change before and after the merging. That is, simply joining the flow paths that have been separate flow paths at the downstream position of the electrolytic cell D increases the back pressure on the side where the flow rate has increased, and the pressure in the electrolytic cell D may change. However, a change in the back pressure does not occur when the flow is divided at the upstream position of the electrolytic cell D simultaneously with the merge at the downstream position. Therefore, a burden is not imposed on the diaphragm Sp provided inside the electrolytic cell D.

  Next, the control method of the electrolyzed water generating apparatus M will be described with reference to FIGS.

  FIG. 6 is a system block diagram of the electrolyzed water generating apparatus M. As shown in FIG. 6, the control means 40 of the electrolyzed water generating apparatus M is set at the center position. The control means 40 is connected to input means such as a start switch 41, an electrolytic hydrogen water mode switch 42, an electrolytic acid water mode switch 43, an electrolytic mixed water mode switch 44, a purified water mode switch 45, a water amount setting switch 46, etc. doing. These input means are configured to transmit a predetermined input signal to the control means 40 by an action (pressing operation) operated by an operator.

  The control means 40 is connected to output means such as a water source valve motor m1, a double cross line valve motor m2, a flow rate control valve motor m3, a first electrode 6a, and a second electrode 6b. These output means are each operating mechanism or each operating element that operates in response to a control signal output by arithmetic processing by the control means 40.

  Further, a timer 47 that counts the operation time and a storage unit 48 that stores a calculation program and the like are connected to the control unit 40. In addition, although not shown, various sensors that detect various conditions, water flow information, and the like are also connected to the control means 40.

(Main control Fm)
FIG. 7 is a flowchart of the main control Fm of the electrolyzed water generating apparatus M. The electrolyzed water generating apparatus M performs main control by the main control Fm. As shown in FIG. 7, first, various conditions are read in S1. Here, information such as information input by the operator, information at the previous control cycle, and current timer value is read.

  Next, it is determined whether or not the start switch 41 has been pressed in S2. The start switch 41 is a switch for operating the electrolyzed water generating apparatus M (water electrolysis operation or the like). If the start switch 41 is pressed, the process proceeds to S3 with YES. On the other hand, if the start switch 41 is not pressed, the process proceeds to S4 with NO. The main power switch of the electrolyzed water generator M is set separately from the start switch 41, although not shown.

  If it transfers to S3, in S3, the water source valve motor m1 will be operated in the present mode state, the water source valve 2A will be open | released, and the flow of water will be started. At the same time, water is electrolyzed. This electrolysis and the like will be described in various modes described later.

  Thereafter, the process proceeds to the water stop control Fc, and the process proceeds to the timer control Ft. The water stop control Fc and the timer control Ft will also be described with reference to FIGS. Then, after the timer control Ft, the process shifts to return and shifts to the next control cycle.

  If it transfers to S4, it will be judged in S4 whether the electrolytic hydrogen water mode switch 42 was pushed. The electrolytic hydrogen water mode switch 42 is a switch for switching to a mode in which the electrolytic hydrogen water is drained from the first electrolytic water discharge port 10a. When the electrolytic hydrogen water mode switch 42 is pressed, the electrolytic hydrogen water mode is YES. The control shifts to the water mode switching control F1. On the other hand, if the electrolytic hydrogen water mode switch 42 is not pressed, the process proceeds to S5 with NO. The switching control F1 to the electrolytic hydrogen water mode will be described later with reference to FIG.

  If it transfers to S5, it will be judged in S5 whether the electrolytic acid water mode switch 43 was pushed. The electrolytic acid water mode switch 43 is a switch for switching to a mode in which the electrolytic acid water is drained from the first electrolyzed water discharge port 10a. When the electrolytic acid water mode switch 43 is pressed, the electrolytic acid water is selected as YES. The control shifts to the water mode switching control F2. On the other hand, if the electrolytic acid water mode switch 43 is not pressed, the process proceeds to S6 with NO. The switching control F2 to the electrolytic acid water mode will be described later with reference to FIG.

  If it transfers to S6, it will be judged whether the electrolytic water mixing mode switch 44 was pushed in S6. This electrolytic mixed water mode switch 44 is a switch for switching to a mode in which electrolytic mixed water is drained from the first electrolytic water discharge port 10a. When this electrolytic mixed water mode switch 44 is pressed, the electrolytic mixed water is YES. The control shifts to the water mode switching control F3. On the other hand, if the electrolytic mixed water mode switch 44 is not pressed, the process proceeds to S7 with NO. The switching control F3 to the electrolytic mixed water mode will be described later with reference to FIG.

  If it transfers to S7, it will be judged in S7 whether the water purification mode switch 45 was pushed. The water purification mode switch 45 is a switch for switching to a mode in which purified water is drained from the first electrolyzed water discharge port 10a. When the water purification mode switch 45 is pressed, the control for switching to the water purification mode F4 is YES. Transition. On the other hand, if the water purification mode switch 45 is not pushed, it returns to NO with return. The switching control F4 to the water purification mode will be described later with reference to FIG.

  The above control steps are steps of the main control Fm of the electrolyzed water generating device. Next, the control flow in each mode will be described with reference to each drawing.

(Switching control F1 to electrolytic hydrogen water mode)
FIG. 8 is a flowchart of the switching control F1 to the electrolytic hydrogen water mode. As shown in FIG. 8, first, in S10, it is determined whether the immediately preceding (previous) mode is the electrolytic hydrogen water mode. If the mode is the electrolytic hydrogen water mode, the process proceeds to S11 with YES. If it is not the electrolytic hydrogen water mode, the process proceeds to S12 with NO. In S11, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged.

  On the other hand, in S12, it is determined whether the immediately preceding (previous) mode is the electrolytic acid water mode. If the mode is electrolytic acid water mode, the process proceeds to S13 with YES. If it is not the electrolytic acid water mode, the process proceeds to S14 with NO. In S13, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged.

  In S14, it is determined whether the immediately preceding (previous) mode is an electrolytic mixed water mode or a purified water mode. If the electrolytic mixed water mode or the purified water mode is selected, the process proceeds to S15 with YES. When it is not the electrolytic mixed water mode or the purified water mode, the process returns to NO at NO.

  In S15, it is determined whether or not the position of the double cross line valve 1 is 0 ° in the mode of the control cycle two times before. If it is 0 °, the process proceeds to S16 with YES, and if it is not 0 °, the process proceeds to S17 with NO.

  In S16, the control of the double cross line valve motor m2 is performed to switch the position of the double cross line valve 1 to 90 °. On the other hand, in S17, the control of the double cross line valve motor m2 is performed so that the position of the double cross line valve 1 is switched to 0 °. Such control is performed by reducing the burden on the electrodes 6a and 6b and the diaphragm Sp by using 90 ° and 0 ° evenly without biasing the position of the double cross line valve 1 to one angle as much as possible. Thus, the electrolytic cell D can be used for a long time.

  After the position control of the double cross line valve 1 is performed in S11, S13, S16, and S17, the process proceeds to S18. In S18, it is determined whether the position of the double cross line valve 1 is 0 °. If the position of the double crossline valve 1 is 0 °, the process proceeds to S19 with YES, and if it is not 0 °, that is, if the position of the double crossline valve 1 is 90 °, NO The process proceeds to S20.

  In S19, the first electrode 6a and the second electrode 6a are controlled in "electrode mode A", and in S20, the first electrode 6a and the second electrode 6a are controlled in "electrode mode B". Here, the “electrode mode A” is an electrode mode in which the first electrode 6a is controlled to the cathode (minus electrode) and the second electrode 6b is controlled to the anode (plus electrode). On the other hand, the “electrode mode B” is an electrode mode in which the first electrode 6a is controlled to the anode (plus electrode) and the second electrode 6b is controlled to the cathode (minus electrode).

  As described above, the first electrode 6a and the second electrode 6b are controlled in the two electrode modes, so that in the “electrode mode A”, the first electrode chamber Da becomes the cathode chamber, and the first electrode chamber Da. Thus, electrolytic hydrogen water is generated, the second electrode chamber Db becomes an anode chamber, and electrolytic acidic water is generated in the second electrode chamber Db.

  On the other hand, in the “electrode mode B”, the first electrode chamber Da becomes an anode chamber, electrolytic acid water is generated in the first electrode chamber Da, the second electrode chamber Db becomes a cathode chamber, and the second electrode chamber Electrolytic hydrogen water is generated with Db.

  That is, in the electrode mode A and the electrode mode B, the electrodes 6a and 6b are inverted to generate electrolytic hydrogen water and electrolytic acid water in the first electrode chamber Da and the second electrode chamber Db, respectively. Can do it.

  Thereafter, the flow shifts from S19 and S20 to return, and the flow returns to the flow of the main control Fm in FIG.

  In the next control cycle of the switching control F1 to the electrolyzed hydrogen water mode, when the operator presses the start switch 41 (S2), raw water flows into the electrolyzed water generator M and electrolysis is performed from the first electrolyzed water discharge port 10a. Hydrogen water is drained.

  Specifically, in the electrolytic hydrogen water mode, when the water source valve motor m1 is operated to open the water source valve 2A (S3), the raw water flows through the water purifier J to be purified and becomes purified water. 3. Pass through the first water inlet 4a and the second water inlet 4b, respectively, and enter the right portion 1A of the double crossline valve 1 from the first inlet 13a and the second inlet 13b.

  At this time, when the position of the double cross line valve 1 is 0 °, the water flow path is defined in the state of FIG. 3, so the purified water that has entered from the first inlet 13a is electrolyzed from the first outlet 15a. It flows into the first electrode chamber Da of the tank D. Moreover, the purified water which entered from the 2nd inlet 13b flows into the 2nd electrode chamber Db of the electrolytic cell D from the 2nd outlet 15b.

  And in electrode mode A, since the 1st electrode chamber Da is controlled to the cathode chamber and the 2nd electrode chamber Db is controlled to the anode chamber, the purified water of the 1st electrode chamber Da is electrolyzed by electrolytic hydrogen water. Thus, the purified water in the second electrode chamber Db is electrolyzed into electrolytic acid water.

  Thereafter, the electrolytic hydrogen water in the first electrode chamber Da enters the left portion 1B of the double cross line valve 1 through the first reinlet 16a and exits from the first reoutlet 14a through the first extraction water passage 7a. And this electrolyzed hydrogen water is drained from the 1st electrolyzed water drain opening 10a through the 1st drainage channel 8a.

  On the other hand, the electrolytic acid water in the second electrolysis chamber Db sequentially passes through the second extraction water passage 7b, the second re-inlet port 16b, the second re-outlet port 14b, and the second drainage passage 8b of the double crossline valve 1A. The water is drained from the second electrolytic drain port 10b.

  As described above, when the electrolyzed water generating apparatus M of the present embodiment is switched to the electrolyzed hydrogen water mode and the electrolysis of water is performed by pressing the start switch 41, electrolysis is performed from the first electrolytic drain port 10a. Hydrogen water can be drained, and electrolytic acid water can be drained from the second electrolytic drain port 10b.

(Switching control to electrolytic acid water mode F2)
FIG. 9 is a flowchart of the switching control F2 to the electrolytic acid water mode. As shown in FIG. 9, first, in S21, it is determined whether the immediately preceding (previous) mode is the electrolytic hydrogen water mode. In the case of the electrolytic hydrogen water mode, the process proceeds to S22 with YES. If it is not the electrolytic hydrogen water mode, the process proceeds to S23 with NO. In S22, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged.

  On the other hand, in S23, it is determined whether the immediately preceding (previous) mode is the electrolytic acid water mode. If the mode is electrolytic acid water mode, the process proceeds to S24 with YES. If it is not the electrolytic acid water mode, the process proceeds to S25 with NO. In S24, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged.

  In S25, it is determined whether the immediately preceding (previous) mode is an electrolytic mixed water mode or a purified water mode. If it is the electrolytic mixed water mode or the purified water mode, the process proceeds to S26 with YES. When it is not the electrolytic mixed water mode or the purified water mode, the process returns to NO at NO.

  In S26, it is determined whether or not the position of the double cross line valve 1 was 0 ° in the mode of the control cycle two times before. If it is 0 °, the process proceeds to S27 with YES, and if it is not 0 °, the process proceeds to S28 with NO.

  In S27, the control of the double cross line valve motor m2 is performed to switch the position of the double cross line valve 1 to 90 °. On the other hand, in S28, the control of the double cross line valve motor m2 is performed so that the position of the double cross line valve 1 is switched to 0 °. Again, this control is performed by using 90 ° and 0 ° equally without biasing the position of the double crossline valve 1 to one angle as much as possible, similar to S16 and S17 described above. This is to reduce the burden on the electrodes 6a and 6b and the diaphragm Sp so that the electrolytic cell D can be used for a long time.

  After controlling the position of the double cross line valve 1 in S22, S24, S27, and S28, all proceeds to S29. In S29, it is determined whether the position of the double cross line valve 1 is 0 °. If the position of the double cross line valve 1 is 0 °, the process proceeds to S30 with YES, and if it is not 0 °, that is, 90 °, the process proceeds to S31 with NO. In S30, the electrode mode B, that is, the first electrode 6a is controlled to the anode (plus electrode), and the second electrode 6b is controlled to the cathode (minus electrode). On the other hand, in S31, the electrode mode A, that is, the first electrode 6a is controlled to the cathode (minus electrode) and the second electrode 6b is controlled to the anode (plus electrode).

  Thereafter, the process shifts from S30 and S31 to return, and returns to the flow of the main control Fm in FIG.

  In the next control cycle of the switching control F2 to the electrolytic acid water mode, when the operator presses the start switch 41 (S2), the raw water flows through the electrolyzed water generating device M and electrolyzes from the first electrolyzed water outlet 10a. Acidic water is drained.

  Here, since the switching control F2 to the electrolytic acid water mode is different from the switching control F1 to the electrolytic hydrogen water mode only in the electrode mode, specifically, only the point of this electrode mode will be described. That is, when the position of the double cross line valve 1 is 0 °, the mode shifts to the electrode mode B, and when the position of the double cross line valve 1 is 90 °, the mode shifts to the electrode mode A. Therefore (S29, S30, S31), in the first electrode chamber Da, electrolytic acidic water is generated instead of electrolytic hydrogen water, and in the second electrolytic chamber Db, electrolytic hydrogen water is generated instead of electrolytic acidic water. .

  Therefore, in the switching control F2 to the electrolytic acid water mode, the electrolytic acid water is drained from the first electrolytic water discharge port 10a instead of the electrolytic hydrogen water, and the electrolytic acid water is discharged from the second electrolytic water discharge port 10b. Instead, the electrolytic hydrogen water is drained.

  As described above, when the electrolyzed water generating apparatus M according to this embodiment is switched to the electrolytic acid water mode and the electrolysis of water is performed by pressing the start switch 41, electrolysis is performed from the first electrolytic drain port 10a. Acidic water can be drained, and electrolytic hydrogen water can be drained from the second electrolytic drain port 10b.

  By the way, in order to increase the amount of drainage from the first electrolyzed water outlet 10a and reduce the amount of drainage from the second electrolyzed water outlet 10b, the flow control valves 5 and 9 may be operated. That is, if the flow rate of the second water inlet channel 4b and the second drainage channel 8b is reduced by operating the flow rate control valves 5 and 9 by operating the flow rate control valve motor m3 with a switch (not shown), the first water inlet channel 4a and The flow rate of the first drainage channel 8a is increased (the split ratio of the first inlet channel 4a and the first drainage channel 8a is increased). For this reason, the amount of drainage from the first electrolyzed water outlet 10a is increased, and the amount of drainage from the second electrolyzed water outlet 10b is decreased. In addition, what is necessary is just to perform the action | operation of this flow control valve 5 and 9 according to a worker's request | requirement.

(Switching control to electrolytic water mode F3)
FIG. 10 is a flowchart of the switching control F3 to the electrolytic mixed water mode. As shown in FIG. 10, first, in S32, it is determined whether the immediately preceding (previous) mode is the electrolytic hydrogen water mode. In the case of the electrolytic hydrogen water mode, the process proceeds to S33 with YES. If it is not the electrolytic hydrogen water mode, the process proceeds to S34 with NO. In S33, the control of the double cross line valve motor m2 is performed to switch the position of the double cross line valve 1 to 45 °.

  On the other hand, in S34, it is determined whether the immediately preceding (previous) mode is the electrolytic acid water mode. In the case of the electrolytic acid water mode, the process proceeds to S33 with YES, similar to S32 described above. If it is not the electrolytic acid water mode, the process proceeds to S35 with NO.

  In S35, it is determined whether the immediately preceding (previous) mode is an electrolytic mixed water mode or a purified water mode. If it is the electrolytic mixed water mode or the purified water mode, the process proceeds to S36 with YES. When it is not the electrolytic mixed water mode or the purified water mode, the process returns to NO at NO.

  In S36, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged. This is because when the previous mode is the electrolytic mixed water mode or the purified water mode, the position of the double cross line valve 1 is 45 ° in the first place, so there is no need to change the position as it is.

  After controlling the position of the double cross line valve 1 in S33 and S36, all shifts to S37. In S37, the electrode mode is controlled, but the electrode mode A and the electrode mode B are controlled as they are. This is because, in the electrolytic mixed water mode, whatever the electrode mode is, it is the electrolytic mixed water that is finally generated. Therefore, any electrolysis can be performed in the first electrode chamber Da and the second electrode chamber Db. This is because even if water is generated, there is no effect.

  Thereafter, the process proceeds from S37 to RETURN and returns to the flow of the main control Fm in FIG.

  In the next control cycle of the switching control F3 to the electrolytic mixed water mode, when the operator presses the start switch 41 (S2), the raw water flows through the electrolytic water generating device M, and the electrolytic mixed water is discharged from the first electrolytic water. It is drained from the outlet 10a.

  Specifically, in the electrolytic mixed water mode, when the water source valve motor m1 is operated to open the water source valve 2A (S3), the raw water flows through the water purifier J to be purified to become purified water, 3. Passes through the first water inlet 4a and enters the right portion 1A of the double cross line valve 1 from the first inlet 13a.

  At this time, since the double crossline valve 1 is at a 45 ° position and the flow path of water is defined at the position shown in FIG. 5, the purified water that has entered from the first inflow port 13a flows into the first outflow port 15a and the second outflow port 15b. The flow is divided and flows into the first electrode chamber Da and the second electrode chamber Db of the electrolytic cell D, respectively. On the other hand, the purified water from the second inlet 13 b is blocked by the first convex portion 23, and therefore does not flow into the double cross line valve 1.

  And, for example, if the electrode mode is electrode mode A, the first electrode chamber Da is controlled to the cathode chamber and the second electrode chamber Db is controlled to the anode chamber, so the purified water that has entered the first electrode chamber Da is The purified water electrolyzed in the electrolytic hydrogen water and entered the second electrode chamber Db is electrolyzed in the electrolytic acid water.

  Then, the electrolytic hydrogen water in the first electrode chamber Da flows through the first extraction water passage 7a and enters the first reinlet 16a of the double crossline valve 1, and the electrolytic acid water in the second electrode chamber Db is second It flows through the extraction water channel 7b and enters the second re-inlet port 16b of the double cross line valve 1.

  Then, the electrolytic hydrogen water and the electrolytic acid water merge at the left portion 1B of the double cross line valve 1 and exit from the first re-outlet 14a as electrolytic mixed water. And this electrolysis mixed water flows through the 1st drainage channel 8a, and is drained from the 1st electrolysis water drainage port 10a. In addition, since the 2nd re-outlet 14b is sealed off by the 3rd convex part 25 from the 2nd electrolyzed water drain port 10b, electrolytic mixed water etc. are not drained.

  As described above, when the electrolyzed water generating apparatus M of the present embodiment is switched to the electrolyzed mixed water mode and the electrolysis of water is performed by pressing the start switch 41, electrolysis is performed from the first electrolysis drainage port 10a. The mixed water can be drained.

  That is, the purified water is diverted at the right side portion 1A of the double cross line valve 1 and then sent to the electrolytic cell D, where it is electrolyzed in the electrolytic cell D and then merged at the left side portion 1B of the double cross line 1. Then, it is drained as electrolytic mixed water.

  In particular, in this embodiment, since the diversion ratio and the merging ratio of the double cross line valve 1 are the same, the internal pressure of the electrolytic cell D does not change before and after switching to the mixed water mode. For this reason, a burden is not given to the diaphragm Sp of the electrolytic cell D. Therefore, according to this embodiment, the electrolytic cell D can be used for a long time.

(Switching control to clean water mode F4)
FIG. 11 is a flowchart of the switching control F4 to the water purification mode. As shown in FIG. 11, first, in S40, it is determined whether the immediately preceding (previous) mode is the electrolytic hydrogen water mode. If the mode is the electrolytic hydrogen water mode, the process proceeds to S41 with YES. If the mode is not the electrolytic hydrogen water mode, the process proceeds to S42 with NO. In S41, the double cross line valve motor m2 is controlled so that the position of the double cross line valve 1 is switched to 45 °.

  On the other hand, in S42, it is determined whether the immediately preceding (previous) mode is the electrolytic acid water mode. In the case of the electrolytic acid water mode, the process proceeds to S41 with YES as in S40 described above. If it is not the electrolytic acid water mode, the process proceeds to S43 with NO.

  In S43, it is determined whether the immediately preceding (previous) mode is an electrolytic mixed water mode or a purified water mode. If it is the electrolytic mixed water mode or the purified water mode, the process proceeds to S44 with YES. When it is not the electrolytic mixed water mode or the purified water mode, the process returns to NO at NO.

  In S44, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged. This is because when the previous mode is the electrolyzed mixed water mode or the purified water mode, the position of the double crossline valve 1 is 45 °, so there is no need to change the position as it is.

  After controlling the position of the double cross line valve 1 in S41 and S44, the process proceeds to S45. In S45, control is performed such that the electrode mode A and the electrode mode B remain as they are. However, control is performed so that electrolysis is not performed. Although the electrode mode setting itself is not changed, even in the case where the start switch 41 is pressed and water is supplied in the next control cycle, electrolysis is not performed in S3 of FIG. 7 ( The power supply is stopped). Thereby, purified water can be poured into the electrolytic cell D with purified water.

  Thereafter, the process proceeds from S45 to RETURN and returns to the flow of the main control Fm in FIG.

  In the next control cycle of the switching control F4 to the water purification mode, when the operator presses the start switch 41 (S2), the raw water flows through the electrolyzed water generating device M, and the purified water remains as it is from the first electrolyzed water discharge port 10a. It is drained.

  The specific flow of water is the same as that in the above-described electrolytic mixed water mode, and power is not supplied to the first electrode 6a and the second electrode 6b.

  Thus, in the electrolyzed water generating apparatus M of this embodiment, when the start switch 41 is pressed after switching to the water purification mode, the purified water can be drained from the first electrolytic drainage port 10a. By having the water purification mode in this way, the electrolyzed water generating apparatus of the present embodiment can obtain not only electrolyzed water such as electrolyzed mixed water but also purified water.

Moreover, since the purified water flows in the electrolytic cell D in such a purified water mode, the diaphragm Sp, the first electrode 6a, and the second electrode 6b in the electrolytic cell D can be washed with purified water. can do.
(Water stop control Fc)
FIG. 12 is a flowchart of the water stop control Fc. When the water stop control Fc reaches the set amount of water and stops or when the start switch 41 is pressed again during the electrolysis control or the like to stop the water, the stop position of the double cross line valve 1 is This is a control for deciding where to go. For the set water amount, the operator sets the water amount by the water amount setting switch 46. For example, it is conceivable to set the amount of water from 10 liters to 2000 liters in increments of 10 liters.

  As shown in FIG. 12, first, in S50, it is determined whether the amount of water that has been continuously flowed has reached the set amount of water and stopped, or whether the start switch 41 has been pressed again to stop water. If the water does not stop, the process proceeds to return with NO. In this case, the flow returns to the flow of the main control Fm in FIG. On the other hand, if the water has stopped, the process proceeds to S51 with YES.

  In S51, it is determined whether the current mode is an electrolytic mixed water mode or a purified water mode. In the case of the electrolytic mixed water mode or the purified water mode, the process proceeds to S52 with YES. On the other hand, when it is not electrolytic mixed water mode or purified water mode, it transfers to S53 by NO.

  In S52, the control of the double cross line valve motor m2 is performed such that the position of the double cross line valve 1 remains unchanged. This is because the position of the double cross line valve 1 is set to 45 °, so that the next time the double cross line valve 1 is operated, not only to the 45 ° position, but also to the 0 ° position and the 90 ° position. It is because it is easy to move.

  In S53, it is determined whether the current mode is an electrolytic hydrogen water mode. If the mode is electrolytic hydrogen water mode, the process proceeds to S54 with YES. If it is not the electrolytic hydrogen water mode, the process proceeds to S55 with NO. In S55, it is determined whether the current mode is an electrolytic acid water mode. If the electrolytic acid water mode is selected, the process proceeds to S54 in the same manner as YES. When the mode is not the electrolytic acid water mode, the process returns to NO with return.

  In S54, it is determined whether the position of the double cross line valve 1 is 0 °. If the position of the double cross line valve 1 is 0 °, the process proceeds to S56 with YES. When the position of the double cross line valve 1 is not 0 °, that is, when the position of the double cross line valve 1 is 90 °, the process proceeds to S57.

  In S56, the double cross line valve motor m2 is controlled so that the position of the double cross line valve 1 is switched to 90 °. This is because the position of the double cross line valve 1 is 0 ° until this period, so that the position of the double cross line valve 1 is changed to 90 ° during the next electrolysis. This is to avoid biasing to 0 °.

  On the other hand, in S57, it is determined whether the double cross line valve 1 has stopped at the 90 ° position for a total of 12 times. This is because the inside of the double cross line valve 1 is contaminated with scale or the like when used for a long time, and therefore the inside of the double cross line valve 1 is washed by rotating the inner cylinder 20 in the reverse direction. Note that after the cleaning operation is performed, the value of the cumulative stop count at the 90 ° position is reset to zero.

  After that, in S58, the control of the double cross line valve motor m2 is performed to switch the position of the double cross line valve 1 to 0 °. This is because the position of the double crossline valve 1 is 90 ° until this period, so that the position of the double crossline valve 1 is set to 0 ° during the next electrolysis. This is so as not to be biased to 90 °.

  Thereafter, the flow shifts from S52, S56, and S58 to return, and the flow returns to the flow of the main control Fm in FIG.

  Thus, in the electrolyzed water generating apparatus M of the present embodiment, when the water flow is stopped and the electrolysis is finished by performing the water stop control Fc, the stop position of the double cross line valve 1 is set to each mode. Switch with. Therefore, since the flow path of the double cross line valve 1 is not biased, the life of the electrolytic cell D can be extended. Moreover, since the double cross line valve 1 itself is cleaned independently, the life of the double cross line valve 1 can be extended.

(Timer control Ft)
FIG. 13 is a flowchart of the timer control Ft. This timer control Ft is designed to remove the scale attached to the electrodes 6a and 6b. When the electrolysis is continued for a certain time or longer, the flow of water is temporarily stopped to change the polarity of the electrodes 6a and 6b. It is the control which starts the flow of water again after reversing.

  As shown in FIG. 13, first, in S60, it is determined whether the current mode is an electrolytic mixed water mode. In the case of the electrolytic mixed water mode, the process proceeds to the electrode control Fa in the electrolytic mixed water mode with YES. The electrode control Fa in the electrolytic mixed water mode will be described later with reference to FIG.

  If it is not the electrolytic mixed water mode, the process proceeds to S61 with NO. In S61, it is determined whether the electrolysis is performed for 20 minutes or more. That is, it is determined whether or not the electrolysis is continued for a certain time or more. Note that the 20 minutes is only a guide value and is not limited to this time.

  If the electrolysis has been performed for 20 minutes or more, the process proceeds to S62 with YES. If the electrolysis has not been performed for 20 minutes or more, a return is made to NO. In S62, the water source valve motor m1 is operated to close the water source valve 2A and stop water. That is, the flow of water is once stopped. This is because the electrolytic hydrogen water and the acidic acidic water drained from the first electrolyzed water outlet 10a and the second electrolyzed water outlet 10b are mixed unintentionally when the electrodes 6a and 6b described later are inverted. Is to prevent.

  Thereafter, in S63, it is determined whether the position of the double cross line valve 1 is 0 °. If the position of the double crossline valve 1 is 0 °, the process proceeds to S64 with YES. On the other hand, when the position of the double cross line valve 1 is not 0 °, that is, when the position of the double cross line valve 1 is 90 °, the process proceeds to S65.

  In S64, the double cross line valve motor m2 is controlled so that the position of the double cross line valve 1 is switched to 90 °. That is, the flow path of the water is switched by switching the position of the double cross line valve 1 from 0 ° to 90 °.

  On the other hand, in S65, the control of the double cross line valve motor m2 is performed so that the position of the double cross line valve 1 is switched to 0 °. That is, in this case, conversely, the position of the double cross line valve 1 is switched from 90 ° to 0 °.

  Thereafter, the process proceeds from S64 to S66. In S66, the current electrode mode is switched to the other electrode mode. That is, if it is electrode mode A, it switches to electrode mode B, and if it is electrode mode B, it switches to electrode mode A. Thereby, the poles of the first electrode 6a and the second electrode 6b are reversed, and the electrolytic hydrogen water and the electrolytic acid water generated in the first electrode chamber Da and the second electrode chamber Db are switched.

  Also, the process proceeds from S65 to S67, and the current electrode mode is switched to another electrode mode. Here again, the poles of the first electrode 6a and the second electrode 6b are inverted, the poles of the first electrode chamber Da and the second electrode chamber Db are inverted, and the electrolyzed water generated in each electrode chamber Da, Db. Is switched.

  Thereafter, the process proceeds from S66 and S67 to S68. In S68, the water flow once stopped is restarted by operating the water source valve motor m1 to open the water source valve 2A. In this way, water is electrolyzed without mixing the electrolytic hydrogen water and the electrolytic acid water.

  Then, the process shifts from Fa, S68 to return, and returns to the flow of the main control Fm in FIG.

  Thus, in the electrolyzed water generating apparatus M of the present embodiment, by performing the timer control Ft, the polarities of the first electrode 6a and the second electrode 6b are periodically switched, so the scale of the electrodes 6a and 6b is scaled. Adhesion is suppressed, and the lifetime of the first electrode 6a and the second electrode 6b can be extended. In addition, since the ion moving direction periodically changes, the burden on the diaphragm Sp can be reduced, and the life of the diaphragm Sp can be extended.

(Electrode control Fa in electrolytic mixed water mode)
FIG. 14 is a flowchart of the electrode control Fa in the electrolytic mixed water mode. As shown in FIG. 14, first, in S70, it is determined whether electrolysis is performed for 20 minutes or more. That is, it is determined whether or not the electrolysis is continued for a certain time or more.

  If the electrolysis has not been performed for 20 minutes or more, the process proceeds to S71 with NO. On the other hand, if the electrolysis has been performed for 20 minutes or more, the process proceeds to S72 in YES.

  In S71, electrolysis is performed in the same electrode mode. This is because the electrolysis is not performed in the same electrode mode for a certain period of time or longer, and no scale or the like is attached to the electrodes 6a and 6b.

  On the other hand, in S72, the electrolysis is stopped. This is because electrolysis is performed in the same electrode mode continuously for a certain time or more, and there is a high possibility that scales are attached to the electrodes 6a and 6b. Therefore, the electrolysis is temporarily stopped.

  Then, it transfers to S73 and waits for about 5 seconds after electrolysis stop. This is because the movement of ions in the electrolytic cell D is suppressed and the inside of the electrolytic cell D is stabilized. In step S74, it is determined whether the current electrode mode is the electrode mode A.

  If it is determined in S74 that the electrode mode is A, the process proceeds to S75 to switch to electrode mode B. On the other hand, when it is not the electrode mode A, that is, in the case of the electrode mode B, the process proceeds to S76 to switch to the electrode mode A. In this way, the electrode mode is switched to the opposite electrode mode, and the poles of the electrodes 6a and 6b are inverted. Thereby, the scale adhering to the electrodes 6a and 6b is removed.

  Thereafter, the process proceeds to S77 and waits for about 2 seconds after switching. This is also for stabilization in the electrolytic cell D. And after that, it transfers to S78 and restarts the electrolysis of water.

  Thus, the process shifts from S71 and S78 to return, and the process returns to the flow of the timer control Ft in FIG.

  Thus, in the electrolyzed water generating apparatus M of this embodiment, by performing the electrode control Fa in the electrolyzed mixed water mode, the polarities of the first electrode 6a and the second electrode 6b are regular even in the electrolyzed mixed water mode. Therefore, the scales are prevented from adhering to the electrodes 6a and 6b, and the lifetimes of the first electrode 6a and the second electrode 6b can be extended. In addition, since the ion moving direction also changes periodically, the burden on the diaphragm Sp can be reduced, and the life of the diaphragm Sp can be further extended. In particular, in the electrode control Fa in the electrolytic mixed water mode, the polarity of the electrodes 6a and 6b can be switched without stopping the flow of water, so that the amount of drainage of electrolytic mixed water or the like is not reduced.

  The electrolyzed water generating apparatus of the present embodiment has the following effects by being controlled by the above control method.

  Even when the electrolytic acid water and the electrolytic hydrogen water are combined at the downstream position of the electrolytic cell D by the double cross line valve 1 when the electrolytic mixed water is generated, the purified water is the same as the combined ratio at the upstream position of the electrolytic cell D. Since the current is divided into the first electrode chamber D1 and the second electrode chamber D2 at a ratio, no pressure change occurs between the first electrode chamber D1 and the second electrode chamber D2, and no load is generated on the diaphragm Sp. Therefore, while the electrolytic water is generated by the electrolytic water generator M, the burden on the diaphragm Sp of the electrolytic cell D can be reduced and the life of the electrolytic cell D can be extended.

  Moreover, since the polarity of the first electrode 6a and the polarity of the second electrode 6b are reversed after elapse of a predetermined time by the electrode control Fa in the electrolytic mixed water mode, the scale attached to the electrodes 6a and 6b can be removed. Therefore, the electrolysis power of the electrolytic cell D can be maintained for a long time. In addition, since the polarity of the electrodes 6a and 6b is reversed with respect to the diaphragm Sp, the ion movement direction is reversed, so that the ion movement is not biased and the burden on the diaphragm Sp can be reduced. Therefore, the lifetime of the electrodes 6a and 6b can be extended, and the performance of the diaphragm Sp can be maintained for a long time.

  Moreover, by making the electrolyzed water production | generation apparatus M into the water purification mode by switching control F4 to the water purification mode, purified water is drained as it is from the first electrolyzed water outlet 10a, and purified water is obtained in addition to the electrolyzed water. Can do. And since purified water flows in the electrolytic cell D as it is, the diaphragm Sp of the electrolytic cell D, electrode 6a, 6b, etc. can be wash | cleaned, The lifetime of the diaphragm Sp etc. can also be lengthened. Therefore, purified water can be obtained in addition to the electrolytically mixed water. Moreover, the lifetime of a diaphragm, an electrode, etc. can also be lengthened.

  In addition, although this embodiment demonstrated the electrolyzed water generating apparatus M which installed the water purifier J, the electrolyzed water generating apparatus which does not install the water purifier J may be sufficient. In this case, the raw water flows through the electrolytic cell D as it is, and the raw water is drained as it is.

  When the polarities of the first electrode 6a and the second electrode 6b are reversed, the double cross line valve 1 switches the flow path between the upstream position of the electrolytic cell D and the downstream position of the electrolytic cell D. Even if the polarities of 6a and 6b are reversed, the hydrogen water and electrolysis can be reliably performed without changing the polarity of the electrolyzed water drained from the first electrolyzed water drain port 10a and the second electrolyzed water drain port 10b. Acidic water can be obtained. Further, the ratio of raw water flowing into the first electrolysis chamber Da and the second electrolysis chamber Db of the electrolysis tank D with respect to the ratio of electrolysis water flowing out from the first electrolysis chamber Da and the second electrolysis chamber Db of the electrolysis tank D is also shown. Since it changes at the same ratio, the membrane Sp is not burdened, and the life of the membrane Sp can be extended.

  Moreover, in the electrolyzed water generating apparatus M of this embodiment, since the function of two valve bodies is acquired by the single double cross line valve 1, the drive means is sufficient by one of the double cross line valve motors m2. For this reason, it becomes more advantageous in terms of control, cost, and layout space than a configuration in which the valve body is composed of two. In particular, in terms of control, the upstream and downstream positions of the electrolytic cell D must be operated in synchronism with each other. However, since the single double cross line valve 1 is used, the two valve bodies are synchronized. There is no need to plan.

  Moreover, according to the electrolyzed water generating apparatus M of this embodiment, since electrolyzed hydrogen water, electrolyzed acidic water, electrolyzed mixed water, and purified water can be selectively obtained with one apparatus, it can be applied to various applications. . In particular, the electrolytic mixed water obtained by the electrolyzed water generating apparatus M of the present embodiment is particularly preferably applied to plant growth.

  As described above, one embodiment has been described. However, the present invention may be changed as appropriate without departing from the scope of the object, and is not limited to this embodiment.

  As described above, the electrolyzed water generating apparatus according to the present invention is useful in, for example, an electrolyzed water generating apparatus that can generate at least electrolytic mixed water by electrolyzing water.
