[0002] The electrolyzed water supply device includes an electrolyzed water generator, and discharges electrolyzed water generated by the electrolyzed water generator (see, for example, Patent Document 1). [Prior art documents] [Patent documents]

[0003] [Patent Document 1] Japanese Patent Application Laid-Open No. 2015-192966 Summary of the Invention [Problem to be solved by the invention]

[0004] The electrolyzed water generator generates new electrolyzed water when all the electrolyzed water has been discharged. Since it takes a certain amount of time to generate electrolyzed water, there is a waiting period during which the electrolyzed water cannot be discharged for a certain period of time.

[0005] The present disclosure has been made to solve the above problem, and aims to provide a technology that shortens the waiting time during which electrolyzed water cannot be discharged. [Means for solving the problem]

[0006] In order to solve the above problems, an electrolyzed water supply device according to one embodiment of the present disclosure comprises a water supply conduit branching at a branching position from a main water conduit supplying tap water, a first water supply unit connected to the water supply conduit, a second water supply unit connected to the water supply conduit, a chloride ion tank unit storing water supplied from the first water supply unit and into which chloride ions are added, an electrolytic tank unit to which water containing chloride ions from the chloride ion tank unit and water from the second water supply unit are supplied, an electrolysis unit producing electrolyzed water by electrolyzing water containing chloride ions from the electrolytic tank unit, a water supply tank unit to which electrolyzed water from the electrolytic tank unit is supplied, a water intake unit capable of taking in electrolyzed water from the water supply tank unit, a water intake conduit extending from the water intake unit and joining the main water conduit at a joining position, and delivering the electrolyzed water taken in by the water intake unit to the main water conduit, a water level sensor capable of detecting the water level in the water supply tank unit, and a control unit controlling the first water supply unit, the second water supply unit, the electrolysis unit, and the water intake unit. The control unit electrolyzes water containing chloride ions in the electrolytic cell unit using the electrolysis unit to generate electrolyzed water, and then supplies water from the second water supply unit to the electrolytic cell unit to dilute the electrolyzed water in the electrolytic cell unit before supplying it to the water supply tank unit, and causes the water intake unit to take in the electrolyzed water supplied to the water supply tank unit.When the water level sensor detects that the water level in the water supply tank unit has fallen below a reference water level, the control unit supplies water from the first water supply unit to the chloride ion cell unit to dilute the water containing chloride ions in the chloride ion cell unit before supplying it to the electrolytic cell unit, and causes the electrolysis unit to electrolyze the water containing chloride ions in the electrolytic cell unit.

[Figure 2]2(a) to 2(e) are diagrams showing an outline of the operation of the electrolyzed water supply device according to the embodiment. [Figure 3] FIG. 10 is a diagram showing the configuration of an electrolyzed water supply device according to a modified example. DETAILED DESCRIPTION OF THE INVENTION

[0010] Before describing specific examples of the present disclosure, an overview of the examples will be provided. This example relates to an electrolyzed water supply device that generates electrolyzed water and mixes electrolyzed water with tap water to discharge diluted electrolyzed water. The electrolyzed water supply device according to this example includes a chloride ion tank section, an electrolytic tank section, and a water supply tank section, and can simultaneously discharge water from the water supply tank section and generate electrolyzed water in the electrolytic tank section. When a water level sensor detects that the water supply tank section has dropped to a reference water level before all the electrolyzed water in the water supply tank has been discharged, the electrolyzed water supply device generates electrolyzed water in the electrolytic tank section. As a result, after all the electrolyzed water in the water supply tank section has been discharged, the electrolyzed water supply device immediately supplies electrolyzed water from the electrolytic tank section to the water supply tank section.

[0011] Hereinafter, embodiments of the present disclosure will be described with reference to the accompanying drawings. Figures 1(a)-(d) show an outline of the operation of an electrolyzed water supply device 100. Figure 1(a) shows the configuration of the electrolyzed water supply device 100. The electrolyzed water supply device 100 is connected to a main water channel 10. The electrolyzed water supply device 100 includes a water supply passage 110, a first water supply section 112, a second water supply section 114, a chloride ion supply section 116, an electrolysis section 118, a water intake section 120, a water intake passage 122, a check valve 124, a water level sensor 126, a control section 130, a first solenoid valve 140, a second solenoid valve 142, a chloride ion tank section 150, a first electrolytic tank section 152a and a second electrolytic tank section 152b collectively referred to as the electrolytic tank section 152, a water supply tank section 154, a first separation wall 160, a second separation wall 162, a partition section 164, and a communication opening 166.

[0012] The main water channel 10 is a pipe connected to a water pipe within the facility and supplies tap water. A water supply channel 110 branches off from a branching position 12 of the main water channel 10. The water supply channel 110 carries water (tap water) from the main water channel 10. A first water supply section 112 and a second water supply section 114 are connected to the water supply channel 110. A first solenoid valve 140 is provided in the first water supply section 112. The first solenoid valve 140 opens and closes the first water supply section 112. The opening and closing of the first solenoid valve 140 is controlled by the control section 130. A second solenoid valve 142 is provided in the second water supply section 114. The second solenoid valve 142 opens and closes the second water supply section 114. The opening and closing of the second solenoid valve 142 is controlled by the control section 130.

[0013] The chloride ion tank section 150, the electrolytic tank section 152, and the water tank section 154 are integrally formed and have a box shape with an open top. The chloride ion tank section 150 and the electrolytic tank section 152 are separated by a first separation wall 160, and the electrolytic tank section 152 and the water tank section 154 are separated by a second separation wall 162. The second separation wall 162 is lower than the first separation wall 160. The electrolytic tank section 152 is further divided into a first electrolytic tank section 152a and a second electrolytic tank section 152b by a partition section 164. A communication opening 166 is provided at the bottom of the partition section 164, which is an opening that connects the first electrolytic tank section 152a and the second electrolytic tank section 152b.

[0014] The chloride ion tank section 150 has a structure capable of storing water, and when the first solenoid valve 140 is open, it stores water supplied from the first water supply section 112. A chloride ion supply section 116 is disposed above the opening of the chloride ion tank section 150. The chloride ion supply section 116 can be loaded with an electrolysis accelerator, and when it receives an instruction from the control section 130 to add an electrolysis accelerator, it rotates a tablet injection member (not shown). When the tablet injection member rotates, the electrolysis accelerator falls into the chloride ion tank section 150. The chloride ion supply section 116 counts the number of electrolysis accelerators dropped from the chloride ion supply section 116, and when it determines that one tablet of electrolysis accelerator has fallen into the chloride ion tank section 150, it stops rotating the tablet injection member. The electrolysis accelerator dissolves in the water in the chloride ion tank section 150, producing water containing chloride ions in the chloride ion tank section 150. An example of the electrolysis promoter is sodium chloride, which is formed as an electrolysis promoter tablet. That is, the chloride ion supply unit 116 can supply chloride ions to the chloride ion tank unit 150. The electrolyzed water supply device 100 may not be provided with the chloride ion supply unit 116, and electrolysis promoter tablets may be manually inserted into the chloride ion tank unit 150.

[0015] Water containing chloride ions from the chloride ion tank section 150 is supplied to the first electrolytic tank section 152a through the first separation wall 160. A second water supply section 114 is provided above the first electrolytic tank section 152a, and the first electrolytic tank section 152a stores the water supplied from the second water supply section 114 when the second solenoid valve 142 is open. In the first electrolytic tank section 152a, the water containing chloride ions from the chloride ion tank section 150 and the water from the second water supply section 114 are mixed (hereinafter, the mixed result will also be referred to as "water containing chloride ions"). The water containing chloride ions in the first electrolytic tank section 152a moves to the second electrolytic tank section 152b through the communication opening 166.

[0016] The second electrolytic bath 152b is provided with an electrolysis unit 118. The electrolysis unit 118 is installed so as to be immersed in the water in the second electrolytic bath 152b. When energized based on instructions from the control unit 130, the electrolysis unit 118 electrolyzes the water containing chloride ions in the second electrolytic bath 152b, generating electrolyzed water containing active oxygen species. Here, active oxygen species refers to oxygen molecules and related substances that have higher oxidative activity than normal oxygen. Examples of active oxygen species include so-called active oxygen in the narrow sense, such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide, as well as so-called active oxygen in the broad sense, such as ozone or hypochlorous acid (hypohalous acid). Electrolyzed water is also called hypochlorous acid water, and hypochlorous acid water of a predetermined concentration is generated in the second electrolytic bath 152b. The electrolyzed water generated in the second electrolytic bath 152b is also stored in the first electrolytic bath 152a through the communication opening 166.

[0017] Electrolyzed water from second electrolytic bath 152b is supplied to water supply tank 154 through second separation wall 162. Water intake unit 120 is disposed within water supply tank 154 and is connected to water intake channel 122. Water intake unit 120 is, for example, a pump, and when it operates in response to instructions from control unit 130, it draws electrolyzed water stored in water supply tank 154 toward water intake channel 122 (water intake is possible). Water intake channel 122 is a pipe connecting water supply tank 154 and main water channel 10. Specifically, water intake channel 122 extends from water intake unit 120 and merges with main water channel 10 at junction 14. As a result, water intake channel 122 delivers electrolyzed water taken in by water intake unit 120 to main water channel 10. Check valve 124 prevents tap water from main water channel 10 from flowing toward water supply tank 154.

[0018] The water level sensor 126 can detect the water level of the water tank section 154. For example, the water level sensor 126 detects the water level (hereinafter referred to as the "reference water level") at which electrolyzed water needs to be supplied as the water level of the water tank section 154. The reference water level is set to be higher than the drought water level. Since known technology can be used for the water level sensor 126, a description thereof will be omitted here. When the water level sensor 126 detects that the water level of the water tank section 154 is the reference water level, it notifies the control section 130.

[0019] A third solenoid valve 20 is provided in the main water channel 10 between the branch position 12 and the junction position 14. The third solenoid valve 20 opens and closes the main water channel 10. The opening and closing of the third solenoid valve 20 is controlled by a control unit 130. The control unit 130 is communicatively connected to the third solenoid valve 20, the chloride ion supply unit 116, the electrolysis unit 118, the water intake unit 120, the water level sensor 126, the first solenoid valve 140, and the second solenoid valve 142. The control unit 130 controls the third solenoid valve 20, the chloride ion supply unit 116, the electrolysis unit 118, the water intake unit 120, the first solenoid valve 140, and the second solenoid valve 142. Controlling the first solenoid valve 140 corresponds to controlling the first water supply unit 112, and controlling the second solenoid valve 142 corresponds to controlling the second water supply unit 114.

[0020] 1(b), the control unit 130 opens the first solenoid valve 140 and closes the second solenoid valve 142 and the third solenoid valve 20. In this state, water from the main water passage 10 is supplied to the chloride ion tank section 150 via the branch position 12, the water supply passage 110, and the first water supply section 112. After a predetermined amount of water has been supplied to the chloride ion tank section 150, the control unit 130 closes the first solenoid valve 140. As a result, the supply of water from the first water supply section 112 to the chloride ion tank section 150 is stopped.

[0021] 1(c), the control unit 130 sends an instruction to supply an electrolysis promoter to the chloride ion supply unit 116, and the chloride ion supply unit 116 supplies the electrolysis promoter (chloride ions) to the chloride ion tank unit 150. The amount of electrolysis promoter to be supplied is determined in advance. Water containing chloride ions is produced in the chloride ion tank unit 150.

[0022] In FIG. 1(d), the control unit 130 opens the first solenoid valve 140 and the second solenoid valve 142. The control unit 130 supplies water from the first water supply unit 112 to the chloride ion tank unit 150, causing the water containing chloride ions in the chloride ion tank unit 150 to be supplied to the first electrolytic tank unit 152a across the first separation wall 160. The control unit 130 also supplies water from the second water supply unit 114 to the first electrolytic tank unit 152a. As a result, the water containing chloride ions from the chloride ion tank unit 150 and the water from the second water supply unit 114 are mixed in the first electrolytic tank unit 152a. This corresponds to diluting the water containing chloride ions. The diluted water containing chloride ions (hereinafter also referred to as "water containing chloride ions") also flows through the communication opening 166 to the second electrolytic tank unit 152b. As a result, water containing chloride ions is stored in first electrolytic cell section 152a and second electrolytic cell section 152b. When a predetermined amount of water is supplied from first water supply section 112 and second water supply section 114, control section 130 closes first solenoid valve 140 and second solenoid valve 142.

[0023] 2(a)-(e) show an overview of the operation of the electrolyzed water supply device 100. In FIG. 2(a), the control unit 130 sends a command to energize the electrolysis unit 118, and the electrolysis unit 118 executes the energization. The energization time is determined in advance. That is, the control unit 130 causes the electrolysis unit 118 to electrolyze water containing chloride ions in the second electrolysis bath unit 152b, thereby producing electrolyzed water. As a result, electrolyzed water is produced in the first electrolysis bath unit 152a and the second electrolysis bath unit 152b.

[0024] 2(b), the control unit 130 opens the second solenoid valve 142. The control unit 130 supplies water from the second water supply unit 114 to the first electrolytic bath unit 152a, thereby diluting the electrolyzed water in the second electrolytic bath unit 152b and supplying it to the water supply tank unit 154 across the second separation wall 162. When a predetermined amount of water has been supplied from the second water supply unit 114, the control unit 130 closes the second solenoid valve 142.

[0025] In Fig. 2(c), the control unit 130 sends an operation instruction to the water intake unit 120, and the water intake unit 120 sends the electrolyzed water supplied to the water supply tank unit 154 from the water intake channel 122. The control unit 130 also opens the third solenoid valve 20. This causes water to flow in the main water channel 10. As a result, the electrolyzed water from the water intake channel 122 merges with the water from the main water channel 10, and diluted electrolyzed water is discharged.

[0026] Figure 2(d) shows a state following Figure 2(c). As water is fed by water intake unit 120, the water level in water feed tank unit 154 drops. When the water level in water feed tank unit 154 falls below the reference water level, water level sensor 126 detects that the water level in water feed tank unit 154 has fallen below the reference water level. Water level sensor 126 notifies control unit 130 that the water level in water feed tank unit 154 has fallen below the reference water level.

[0027] 2(e), when control unit 130 is notified by water level sensor 126 that the water level in water supply tank unit 154 has fallen below the reference water level, control unit 130 supplies a certain amount of water from first water supply unit 112 to chloride ion tank unit 150. As a result, the water containing chloride ions in chloride ion tank unit 150 is diluted and supplied to first electrolytic tank unit 152a and second electrolytic tank unit 152b. At this time, control unit 130 may send an instruction to chloride ion supply unit 116 to supply an electrolysis accelerator (chloride ions), and chloride ion supply unit 116 may supply the electrolysis accelerator (chloride ions) to chloride ion tank unit 150.

[0028] Subsequently, as shown in FIG. 2(a), the control unit 130 causes the electrolysis unit 118 to electrolyze the water containing chloride ions in the second electrolytic bath unit 152b to produce electrolyzed water. At this time, the water intake unit 120 continues to feed the electrolyzed water in the water supply bath unit 154 from the water intake channel 122, and as water continues to flow in the main water channel 10, the electrolyzed water from the water intake channel 122 merges with the water from the main water channel 10, and diluted electrolyzed water is discharged. Furthermore, the processes shown in FIGS. 2(b)-(d) are repeatedly executed. As a result, the discharge of diluted electrolyzed water from the electrolyzed water supply device 100 is simply stopped in the state shown in FIG. 2(b), thereby shortening the waiting time during which electrolyzed water cannot be discharged.

[0029] The subject of the device, system, or method of the present disclosure includes a computer. The computer executes a program to realize the functions of the subject of the device, system, or method of the present disclosure. The computer includes, as its main hardware component, a processor that operates according to the program. The processor may be of any type, as long as it can realize the functions by executing the program. The processor may be composed of one or more electronic circuits, including a semiconductor integrated circuit (IC) or a large-scale integration (LSI). The electronic circuits may be integrated into a single chip or may be provided on multiple chips. The multiple chips may be integrated into a single device or may be provided on multiple devices. The program is recorded on a non-transitory recording medium, such as a computer-readable ROM, optical disk, or hard disk drive. The program may be pre-stored on the recording medium or may be supplied to the recording medium via a wide-area communication network, including the Internet.

[0030] (Variation) Next, a modified example will be described. This modified example differs from the previous examples in the configuration of the electrolytic bath section 152. Figure 3 shows the configuration of the electrolyzed water supply device 100. Compared to Figure 1(a), the electrolytic bath section 152 does not have a partition section 164 and a communication opening 166, so it is not divided into a first electrolytic bath section 152a and a second electrolytic bath section 152b. In other words, only one electrolytic bath section 152 is provided. The processing of the control section 130 is the same as the previous examples, so a description thereof will be omitted here.

[0031] According to this embodiment, the chloride ion tank section 150, the electrolytic tank section 152, and the water supply tank section 154 are separated, so that the discharge of water from the water supply tank section 154 and the generation of electrolyzed water from the electrolytic tank section 152 can be carried out simultaneously. Furthermore, because the discharge of water from the water supply tank section 154 and the generation of electrolyzed water from the electrolytic tank section 152 are carried out simultaneously, electrolyzed water is generated in the electrolytic tank section 152 and supplied to the water supply tank section 154 before the electrolyzed water from the water supply tank section 154 is completely discharged, so that the waiting time during which electrolyzed water cannot be discharged can be shortened.

[0032] Furthermore, by supplying water to the chloride ion tank section 150 after water containing chloride ions is produced in the chloride ion tank section 150, the water containing chloride ions is supplied to the electrolytic tank section 152 over the first separation wall 160, so that water containing chloride ions can be sent instead of solid sodium chloride. Furthermore, by sending water containing chloride ions instead of solid sodium chloride, the solid cannot be used for electrolysis, but the water containing chloride ions is used for electrolysis, so loss of sodium chloride can be suppressed.

[0033] Furthermore, since a difference in height is provided between the first separation wall 160 and the second separation wall 162, it is possible to prevent the water in the electrolytic cell section 152 from flowing back into the chloride ion cell section 150. Furthermore, since a difference in height is provided between the first separation wall 160 and the second separation wall 162, it is possible to raise the water levels in the electrolytic cell section 152 and the water supply cell section 154 to a level equal to or higher than that of the second separation wall 162. Furthermore, since the water levels in the electrolytic cell section 152 and the water supply cell section 154 can be raised to a level equal to or higher than that of the second separation wall 162, it is possible to increase the amount of electrolyzed water supplied to the main water channel 10.

[0034] In addition, since the partition 164 separates the first electrolytic bath section 152a and the second electrolytic bath section 152b, when water is supplied from the first water supply section 112 to the chloride ion bath section 150, it is difficult for water containing chloride ions to flow over the second electrolytic bath section 152b and into the water supply bath section 154.
