Summary of the Invention
Problems to be Solved by the Invention
[0004] The opening and closing of the cock for flowing electrolyzed water is manually performed. Therefore, there is a possibility that cleaning cannot be performed at an appropriate timing.
[0005] The present disclosure has been made to solve the above problems, and an object thereof is to provide a technique for cleaning at an appropriate timing.
Means for Solving the Problems
[0006] To solve the above problems, an electrolyzed water supply device according to an aspect of the present disclosure includes a water tank unit that stores water, a chloride ion supply unit that can supply chloride ions into the water tank unit, an electrolysis unit that electrolyzes water having chloride ions in the water tank unit to generate electrolyzed water, a water supply unit that can supply the electrolyzed water stored in the water tank unit to a piping unit, a chloride ion detection unit that detects the presence or absence of supply of chloride ions from the chloride ion supply unit into the water tank unit at every preset time, a valve that opens and closes the piping unit, and a control unit that controls the electrolysis unit, the water supply unit, and the valve. When the chloride ion detection unit detects that the supply is present, the control unit causes the electrolysis unit to generate electrolyzed water, closes the valve, and then causes the water supply unit to supply the electrolyzed water. After causing the water supply unit to supply the electrolyzed water, the control unit opens the valve.
[0007] Furthermore, any combination of the above components, as well as any conversion of the expressions of this disclosure between methods, apparatus, systems, recording media, computer programs, etc., are also valid forms of this disclosure. [Effects of the Invention]

[0010] Before specifically describing the embodiments of this disclosure, an overview of the embodiments will be given. This embodiment relates to an electrolytic water supply device for supplying electrolytic water to clean the washing tank, drain, and piping of a sink. The electrolytic water supply device generates electrolytic water by supplying chloride ions to water and then electrolyzing the water containing chloride ions. If the generated electrolytic water is supplied manually, there is a risk that slime and grime may accumulate in the washing tank, drain, and piping if the electrolytic water is not supplied regularly. The electrolytic water supply device according to this embodiment periodically detects whether chloride ions are being supplied, and if they are being supplied, generates electrolytic water and then supplies it. At that time, the valve in the piping is closed, so that electrolytic water is stored in the piping. After a predetermined period of time, the valve is opened.
[0011] The following describes the implementation of this disclosure, referring to the attached drawings, in the following order: (1) basic configuration, (2) treatment when chloride ions are not replenished, and (3) treatment when chloride ions are replenished.
[0012] (1) Basic configuration Figs. 1(a)-(b) show the main part of the sink where the electrolyzed water supply device 100 is installed. Fig. 1(a) shows the main part of the sink where the electrolyzed water supply device 100 is installed. A bucket-shaped washing tank 12 is installed in the sink, and a piping part 13 is provided at the bottom part of the washing tank 12. The piping part 13 has a drain port 14 and a pipe 16. Specifically, a drain port 14 is provided at the bottom part of the washing tank 12, and the drain port 14 is connected to the hollow pipe 16. A faucet (not shown) is provided at the upper part of the washing tank 12, and the water from the faucet flows from the washing tank 12 through the drain port 14 into the pipe 16. The electrolyzed water supply device 100 generates electrolyzed water and discharges the electrolyzed water into the washing tank 12 from the dedicated faucet 10. The discharged electrolyzed water also flows from the washing tank 12 through the drain port 14 into the pipe 16. A valve 18 is provided in the pipe 16, and the valve 18 opens and closes the pipe 16. Since the valve 18 is closed at the timing when the electrolyzed water is discharged from the electrolyzed water supply device 100, the electrolyzed water is stored in the pipe 16. Thereby, the electrolyzed water washes the washing tank 12, the drain port 14, and the pipe 16. After a predetermined period, the valve 18 is opened and the electrolyzed water flows through.
[0013] In Fig. 1(b), the electrolyzed water supply device 100 is not connected to the dedicated faucet 10 but is connected to the piping part 1(3) (the drain port 14 or the pipe 16). The electrolyzed water supply device 100 directly discharges the electrolyzed water into the piping part 13. Therefore, Fig. 1(b) is a configuration in which the piping part 13 can be efficiently washed with electrolyzed water. Hereinafter, this embodiment will be described based on Fig. 1(b), but the same process may be performed in Fig. 1(a).
[0014] Fig. 2 shows the configuration of the electrolyzed water supply device 100. The electrolyzed water supply device 100 includes a valve 18, a water storage tank part 110, an electrolytic cell part 112, a chloride ion supply part 120, a chloride ion detection part 122, a first water passage 124, a first water supply part 126, a second water passage 128, an electrolysis part 130, a third water passage 132, a second water supply part 134, a fourth water passage 136, and a control part 150.
[0015] The water storage tank section 110 and the electrolytic cell section 112 have a box shape with an open top surface. The water storage tank section 110 stores water. For example, a full water sensor (not shown) and a water shortage sensor (not shown) are installed in the water storage tank section 110, and a water supply section (not shown) is connected thereto. When the water shortage sensor detects water shortage, the water supply section supplies water to the water storage tank section 110, and when the full water sensor detects full water, the water supply section stops the water supply.
[0016] A chloride ion supply section 120 is disposed above the opening of the water storage tank section 110. The chloride ion supply section 120 can supply a raw material containing chloride ions necessary for electrolyzed water generation into the water storage tank section 110. The raw material containing chloride ions is a salt containing chloride that dissolves and ionizes in water, for example, sodium chloride or potassium chloride in powder or solid form, or an aqueous solution containing such a salt. When the raw material is in powder or solid form, the chloride ion supply section 120 periodically supplies a fixed amount of the raw material to the water storage tank section 110, and when the raw material is liquid, the chloride ion supply section 120 periodically pumps and supplies a fixed amount of the raw material to the water storage tank section 110. The chloride ion supply section 120 may supply a raw material containing chloride ions into the water storage tank section 110 when receiving a supply instruction from the control section 150. By the supply of the raw material from the chloride ion supply section 120, water having chloride ions (hereinafter referred to as "chloride ion water") is stored in the water storage tank section 110.
[0017] The chloride ion detection section 122 is disposed in the chloride ion supply section 120 or the water storage tank section 110 or between them, and detects the presence or absence of the supply of chloride ions from the chloride ion supply section 120 into the water storage tank section 110 at preset time intervals. The chloride ion detection section 122 stores the detection result and transmits the detection result to the control section 150 in response to a request from the control section 150. After transmitting the detection result, the chloride ion detection section 122 resets the detection result.
[0018] For example, the chloride ion detection unit 122 is a weight sensor that measures the weight of the water storage tank 110 and detects the presence of a supply when the weight increases. The chloride ion detection unit 122 is a weight sensor that measures the weight of the chloride ion supply unit 120 and detects the presence of a supply when the weight decreases. The chloride ion detection unit 122 is an infrared (light) sensor placed between the chloride ion supply unit 120 and the water storage tank 110 and detects the presence of a supply when it detects an object falling from the chloride ion supply unit 120 into the water storage tank 110. The chloride ion detection unit 122 is a measuring instrument that measures the conductivity of the water stored in the water storage tank 110 and detects the presence of a supply when it electrically detects a change in the conductivity of the water due to the addition of chloride ions. The chloride ion detection unit 122 detects the absence of a supply in all other cases.
[0019] A first water channel 124 is connected to the water storage tank section 110, the first water channel 124 is connected to the first water supply section 126, the first water supply section 126 is connected to a second water channel 128, and the second water channel 128 is connected to the electrolytic cell section 112. The first water channel 124 and the second water channel 128 are tubular in shape. The first water supply section 126 is, for example, a constant flow pump and is capable of supplying a constant amount of water. When the first water supply section 126 receives an operation instruction from the control unit 150, it draws chloride ion water stored in the water storage tank section 110 into the first water channel 124 and supplies the drawn-in chloride ion water to the electrolytic cell section 112 via the second water channel 128.
[0020] As a result, the electrolytic cell 112 is supplied with chloride ion water from the water storage tank 110 and stores the chloride ion water. An electrolytic unit 130 is provided inside the electrolytic cell 112. The electrolytic unit 130 is installed so as to be immersed in the chloride ion water inside the electrolytic cell 112. The electrolytic unit 130 has, for example, at least one pair of electrode plates, and by applying a predetermined voltage between the electrode plates based on instructions from the control unit 150, it electrolyzes the chloride ion water inside the electrolytic cell 112 to produce electrolyzed water containing reactive oxygen species.
[0021] Here, the electrode plate preferably has a catalytic material suitable for generating electrolyzed water, such as platinum or iridium. Furthermore, reactive oxygen species refer to oxygen molecules and related substances that have higher oxidative activity than ordinary oxygen. For example, reactive oxygen species include so-called reactive oxygen species in the narrow sense, such as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide, as well as so-called reactive oxygen species in the broad sense, such as ozone or hypochlorous acid (hypohalous acid). Electrolyzed water is also called hypochlorous acid water.
[0022] A valve 18 is connected to the piping 16. The valve 18 can communicate with the control unit 150, and the valve 18 opens and closes the piping 16 in accordance with the open / close instructions received from the control unit 150. Specifically, when the open / close instruction indicates "open," the valve 18 opens the piping 16, and when the open / close instruction indicates "closed," the valve 18 closes the piping section 13.
[0023] A third water channel 132 is connected to the electrolytic cell section 112, the third water channel 132 is connected to the second water supply section 134, and a fourth water channel 136 is connected to the second water supply section 134. The second water supply section 134 is connected to the piping section 13 in Figure 1. The third water channel 132 and the fourth water channel 136 have a tubular shape. The second water supply section 134 is, for example, a constant flow pump and is capable of supplying a constant amount of water. When the second water supply section 134 receives an operation instruction from the control unit 150, it draws the electrolyzed water stored in the electrolytic cell section 112 into the third water channel 132 and supplies the drawn-in electrolyzed water from the fourth water channel 136 to the piping section 13. When the valve 18 is closed, the electrolyzed water is stored in the piping section 13. After a predetermined time, the valve 18 opens the piping section 13, allowing the electrolyzed water to flow.
[0024] The control unit 150 can communicate with the chloride ion detection unit 122, the first water supply unit 126, the electrolysis unit 130, the second water supply unit 134, and the valve 18. The control unit 150 periodically sends a request to the chloride ion detection unit 122 to transmit the detection result, and receives the detection result from the chloride ion detection unit 122. When the chloride ion detection unit 122 detects that there is a supply, the control unit 150 sends a request to the first water supply unit 126 to send the chloride ion water from the water storage tank unit 110 to the electrolysis cell unit 112. After the chloride ion water has been sent, the control unit 150 sends a request to the electrolysis unit 130 to generate electrolyzed water. Also, when the chloride ion detection unit 122 detects that there is a supply, the control unit 150 sends an open / close instruction to the valve 18, indicating "close", to close the valve 18. After the electrolyzed water is generated, the control unit 150 sends a request for the electrolyzed water to the second water supply unit 134, causing the electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. After a predetermined time has elapsed since the electrolyzed water was sent to the second water supply unit 134, the control unit 150 sends an open / close instruction to the valve 18, indicating "open," causing the valve 18 to open.
[0025] The chloride ion supply unit 120 periodically supplies chloride ions, the chloride ion detection unit 122 periodically detects whether or not chloride ions have been supplied, and the control unit 150 sends electrolyzed water based on the periodically acquired detection results, so that cleaning is performed at the appropriate timing. In addition, since the valve 18 is closed at the time the electrolyzed water is sent, the piping section 13 is cleaned efficiently.
[0026] (2) Treatment when chloride ions are not replenished Up to this point, we have described the operation when the detection result received by the control unit 150 indicates that a supply is available. On the other hand, there are also cases where the detection result indicates that a supply is not available. This means that the chloride ion supply unit 120 is not replenished with raw materials containing chloride ions, that is, it is in an unreplenished state. When the unreplenished state is detected, the control unit 150 executes either (2-1) the first unreplenished process or (2-2) the second unreplenished process.
[0027] (2-1) First Unfilled Processing The electrolytic water supply device 100 has a notification unit (not shown). The notification unit is, for example, a light or a speaker. When the detection result indicates no supply, the control unit 150 instructs the notification unit to send a notification. The notification unit, in response to the instruction from the control unit 150, notifies the system to replenish chloride ions in the chloride ion supply unit 120. The notification of replenishing chloride ions in the chloride ion supply unit 120 is made, for example, by turning on or flashing a light, or by outputting sound from a speaker.
[0028] When the chloride ion detection unit 122 detects that there is no supply, the control unit 150 sends a request to the first water supply unit 126 to send the water stored in the water storage tank unit 110 to the electrolytic cell unit 112. Also, when the chloride ion detection unit 122 detects that there is no supply, the control unit 150 sends an open / close instruction to the valve 18, indicating "close", to close the valve 18.
[0029] After water is supplied, the control unit 150 sends a water supply request to the second water supply unit 134, causing the water from the electrolytic cell unit 112 to be supplied to the piping unit 13. After a predetermined time has elapsed since the second water supply unit 134 supplied water, the control unit 150 sends an open / close instruction, indicated as "open," to the valve 18, causing the valve 18 to open. In other words, the control unit 150 supplies water to the second water supply unit 134 without allowing the electrolytic unit 130 to generate electrolyzed water. As a result, cleaning with water is not performed, but cleaning with electrolyzed water is performed.
[0030] (2-2) Second Unfilled Processing If the control unit 150 detects that there is no supply, it instructs the notification unit to send a notification. The notification unit, in response to the instruction from the control unit 150, notifies the chloride ion supply unit 120 to replenish the chloride ions. This process is the same as (2-1) the first non-replenishment process.
[0031] When the chloride ion detection unit 122 detects that there is no supply, the control unit 150 sends a request to the first water supply unit 126 to send the water stored in the water storage tank unit 110 to the electrolytic cell unit 112. After the water is sent, the control unit 150 sends a request to the electrolytic unit 130 to generate electrolyzed water, thereby generating electrolyzed water without a chloride ion supply. Therefore, the concentration of hypochlorous acid in the generated electrolyzed water is lower than the concentration of hypochlorous acid in electrolyzed water generated with a chloride ion supply. Also, when the chloride ion detection unit 122 detects that there is no supply, the control unit 150 sends an open / close instruction to the valve 18, indicating "closed," to close the valve 18.
[0032] After the electrolyzed water is generated, the control unit 150 sends a request for the electrolyzed water to the second water supply unit 134, causing the electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. After a predetermined time has elapsed since the electrolyzed water was sent to the second water supply unit 134, the control unit 150 sends an open / close instruction, indicated as "open," to the valve 18, causing the valve 18 to open. In other words, the control unit 150 generates electrolyzed water in the electrolysis unit 130 without supplying chloride ions and sends the electrolyzed water to the second water supply unit 134. The cleaning power of this electrolyzed water is lower than usual, but cleaning is performed using such electrolyzed water.
[0033] (3) Treatment when electrolytic ions are replenished This section describes the process when (2) the chloride ion supply unit 120 is refilled with a raw material containing chloride ions after the process for when chloride ions are not replenished has been performed. (2) The process for when chloride ions are not replenished is performed, which reduces the cleaning power compared to when the process for the basic configuration (1) is performed. As a result, slimy buildup may occur in the cleaning tank 12, the drain outlet 14, and the piping 16. To remove the slimy buildup that has occurred, the electrolytic water supply device 100 performs one of the following: (3-1) the first post-refill treatment, (3-2) the second post-refill treatment, (3-3) the third post-refill treatment, or (3-4) the fourth post-refill treatment. In the following, the electrolytic water generated in the electrolysis unit 130 before the chloride ion detection unit 122 detects that there is no supply may be defined as the first electrolytic water.
[0034] (3-1) Post-refill processing The electrolytic water supply device 100 includes a memory unit (not shown). When the detection result indicates no supply, the control unit 150 updates the number of times no supply has been detected (hereinafter referred to as the "number of no supply occurrences") by adding "1", and stores the updated number of no supply occurrences in the memory unit. The number of no supply occurrences indicates the period during which chloride ions have not been replenished, and the larger the number of no supply occurrences, the longer the period during which chloride ions have not been replenished. The longer the period during which chloride ions have not been replenished, the higher the possibility that slime buildup has occurred in the washing tank 12, drain outlet 14, and piping 16. Therefore, it can be said that the higher the number of no supply occurrences, the higher the possibility of slime buildup.
[0035] When the detection result changes from "no supply" to "supply available," the control unit 150 acquires the updated number of "no supply" occurrences and resets the number of "no supply" occurrences stored in the memory unit to zero. The control unit 150 sends a request for the supply of chloride ion water to the first water supply unit 126, causing the chloride ion water from the water storage tank unit 110 to be supplied to the electrolysis cell unit 112. After the chloride ion water has been supplied, the control unit 150 sends a request for the generation of electrolyzed water different from the first electrolyzed water (hereinafter referred to as "second electrolyzed water") to the electrolysis unit 130, causing the second electrolyzed water to be generated.
[0036] Figures 3(a) and 3(b) show the data structure of the table used in the control unit 150. As shown in Figure 3(a), the correspondence between the number of supply cycles and the electrolysis time is shown. The electrolysis time indicates the time for the electrolysis unit 130 to perform electrolysis. Here, the more supply cycles there are, the longer the electrolysis time. Figure 3(b) is omitted, and we return to Figure 2.
[0037] The control unit 150 refers to a table and obtains the electrolysis time corresponding to the number of supply failures obtained. The control unit 150 includes the electrolysis time information in the generation request and transmits it to the electrolysis unit 130. The electrolysis unit 130 generates second electrolyzed water by performing electrolysis for the electrolysis time included in the generation request. In addition, if the chloride ion detection unit 122 detects that there is no supply, the control unit 150 transmits an open / close instruction indicated as "closed" to the valve 18, thereby closing the valve 18.
[0038] After the second electrolyzed water is generated, the control unit 150 sends a request for electrolyzed water to the second water supply unit 134, causing the electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. After a predetermined time has elapsed since the electrolyzed water was sent to the second water supply unit 134, the control unit 150 sends an open / close instruction to the valve 18, indicating "open," causing the valve 18 to open.
[0039] Here, instead of the table in Figure 3(a), the table in Figure 3(b) may be used for the control unit 150. Here, the electrolysis time for generating the first electrolyzed water and the electrolysis time for generating the second electrolyzed water are shown, regardless of the number of supply cycles. Furthermore, the electrolysis time for generating the second electrolyzed water is made longer than the electrolysis time for generating the first electrolyzed water.
[0040] (3-2) Post-refill processing for the second refill The electrolytic water supply device 100 includes a memory unit (not shown). When the detection result indicates no supply, the control unit 150 updates the number of times no supply has been detected (hereinafter referred to as the "number of no supply occurrences") by adding "1", and stores the updated number of no supply occurrences in the memory unit.
[0041] When the detection result changes from "no supply" to "supply available," the control unit 150 acquires the updated number of "no supply" occurrences and resets the number of "no supply" occurrences stored in the memory unit to zero. The control unit 150 sends a request for the supply of chloride ion water to the first water supply unit 126, causing the chloride ion water from the water storage tank unit 110 to be supplied to the electrolysis cell unit 112. After the chloride ion water has been supplied, the control unit 150 sends a request for the generation of electrolyzed water different from the first electrolyzed water (hereinafter referred to as "second electrolyzed water") to the electrolysis unit 130, causing the second electrolyzed water to be generated.
[0042] Figures 4(a) and 4(b) show the data structure of the table used in the control unit 150. As shown in Figure 4(a), the correspondence between the number of supply cycles and the current value is shown. The current value indicates the current value when the electrolysis unit 130 is made to perform electrolysis. Here, the current value increases as the number of supply cycles increases. Figure 4(b) is omitted, and we return to Figure 2.
[0043] The control unit 150 refers to a table and obtains a current value corresponding to the number of times no supply has been obtained. The control unit 150 includes the current value information in the generation request and transmits it to the electrolysis unit 130. The electrolysis unit 130 generates second electrolyzed water by performing electrolysis according to the current value included in the generation request. In addition, if the chloride ion detection unit 122 detects no supply, the control unit 150 transmits an open / close instruction indicated as "closed" to the valve 18, thereby closing the valve 18.
[0044] After the second electrolyzed water is generated, the control unit 150 sends a request for the second electrolyzed water to the second water supply unit 134, causing the second electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. After a predetermined time has elapsed since the second electrolyzed water was sent to the second water supply unit 134, the control unit 150 sends an open / close instruction to the valve 18, indicating "open," causing the valve 18 to open.
[0045] Here, instead of the table in Figure 4(a), the table in Figure 4(b) may be used for the control unit 150. Here, the current value for generating the first electrolyzed water and the current value for generating the second electrolyzed water are shown, regardless of the number of supply cycles. Furthermore, the current value for generating the second electrolyzed water is made greater than the current value for generating the first electrolyzed water.
[0046] (3-3) Post-refill processing for the third refill The electrolytic water supply device 100 includes a memory unit (not shown). When the detection result indicates no supply, the control unit 150 updates the number of times no supply has been detected (hereinafter referred to as the "number of no supply occurrences") by adding "1", and stores the updated number of no supply occurrences in the memory unit.
[0047] When the detection result changes from "no supply" to "supply available," the control unit 150 acquires the updated number of "no supply" occurrences and resets the number of "no supply" occurrences stored in the memory unit to zero. The control unit 150 sends a request for chloride ion water to the first water supply unit 126, causing the chloride ion water from the water storage tank unit 110 to be sent to the electrolytic cell unit 112. After the chloride ion water has been sent, the control unit 150 sends a request for electrolytic water generation to the electrolytic unit 130, causing the electrolytic water to be generated. Furthermore, when the chloride ion detection unit 122 detects "no supply," the control unit 150 sends an open / close instruction indicated as "closed" to the valve 18, causing the valve 18 to close.
[0048] After the electrolyzed water is generated, the control unit 150 sends a request for the electrolyzed water to the second water supply unit 134, causing the electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. Figures 5(a)-(b) show the data structure of the table used in the control unit 150. As shown in Figure 5(a), the correspondence between the number of supply cycles and the closing time is shown. The closing time is the time from when the second water supply unit 134 sends the electrolyzed water from the electrolytic cell unit 112 to the piping unit 13 until the valve 18 is closed. This corresponds to the time from when the second water supply unit 134 sends the electrolyzed water from the electrolytic cell unit 112 to the piping unit 13 until the valve 18 is opened. Here, the more supply cycles there are, the longer the closing time becomes. Figure 5(b) is omitted and we return to Figure 2.
[0049] The control unit 150 refers to a table and obtains the closing time corresponding to the number of supply cycles obtained. After the closing time has elapsed since the second water supply unit 134 supplied electrolyzed water to the control unit 150, it sends an open / close instruction to the valve 18, indicating "open," thereby opening the valve 18.
[0050] Here, instead of the table in Figure 5(a), the table in Figure 5(b) may be used for the control unit 150. Here, the closing time for closing valve 18 before replenishment and the closing time for closing valve 18 after replenishment are shown, regardless of the number of supply cycles. Furthermore, the closing time for closing valve 18 after replenishment is made longer than the closing time for closing valve 18 before replenishment.
[0051] (3-4) Post-refill processing for the fourth refill The electrolytic water supply device 100 includes a memory unit (not shown). When the detection result indicates no supply, the control unit 150 updates the number of times no supply has been detected (hereinafter referred to as the "number of no supply occurrences") by adding "1", and stores the updated number of no supply occurrences in the memory unit.
[0052] When the detection result changes from "no supply" to "supply available," the control unit 150 acquires the updated number of "no supply" occurrences and resets the number of "no supply" occurrences stored in the memory unit to zero. The control unit 150 sends a request for chloride ion water to the first water supply unit 126, causing the chloride ion water from the water storage tank unit 110 to be sent to the electrolytic cell unit 112. After the chloride ion water has been sent, the control unit 150 sends a request for electrolytic water generation to the electrolytic unit 130, causing the electrolytic water to be generated. Furthermore, when the chloride ion detection unit 122 detects "no supply," the control unit 150 sends an open / close instruction indicated as "closed" to the valve 18, causing the valve 18 to close.
[0053] After the electrolyzed water is generated, the control unit 150 sends a request for the electrolyzed water to the second water supply unit 134, causing the electrolyzed water from the electrolytic cell unit 112 to be sent to the piping unit 13. After a predetermined time has elapsed since the electrolyzed water was sent to the second water supply unit 134, the control unit 150 sends an open / close instruction to the valve 18, indicating "open," causing the valve 18 to open.
[0054] Figures 6(a) and 6(b) show the data structure of the table used in the control unit 150. As shown in Figure 6(a), the correspondence between the number of supply cycles and the number of flow cycles is shown. The number of flow cycles indicates the number of times the electrolysis unit 130 generates electrolyzed water and the second water supply unit 134 supplies the electrolyzed water. Here, the more supply cycles there are, the more flow cycles are assigned. We will skip Figure 6(b) and return to Figure 2.
[0055] The control unit 150 refers to a table and obtains the number of flows corresponding to the number of supply cycles obtained. The control unit 150 includes the flow count information in the generation request and sends it to the electrolysis unit 130, includes the flow count information in the water supply request and sends it to the second water supply unit 134, and includes the flow count information in the open / close instruction and sends it to the valve 18. The electrolysis unit 130 generates electrolyzed water for the number of flows, the second water supply unit 134 performs water supply for the number of flows, and the valve 18 opens and closes for the number of flows.
[0056] Here, instead of the table in Figure 6(a), the table in Figure 6(b) may be used in the control unit 150. Here, the number of flows for the electrolyzed water before replenishment and the number of flows for the electrolyzed water after replenishment are shown, without the number of flows depending on the number of supply cycles. Furthermore, the number of flows for the electrolyzed water after replenishment is set to be greater than the number of flows for the electrolyzed water before replenishment.

The control unit 150 resets the number of supply cycles (S190) and returns to step 150.
[0066] Figure 11 is a flowchart showing the processing procedure by the electrolyzed water supply device 100. This is (2-1) the first unreplenished processing and (3-4) the fourth re-replenished processing. The chloride ion detection unit 122 waits for a set time (S200). If chloride ions are supplied (Y in S202), the control unit 150 causes the electrolysis unit 130 to generate electrolyzed water (S204), closes the valve 18 (S206), and then sends the electrolyzed water to the second water supply unit 134 (S208).

The control unit 150 resets the number of supply cycles (S232) and returns to step 200.
[0069] (modified version) Next, a modified example will be described. Figures 12(a) and 12(b) show the configuration of the electrolytic water supply device 100. In Figure 12(a), the water storage tank section 110 and the electrolytic cell section 112 are combined into a water tank section 114. The water tank section 114 stores water. The chloride ion supply section 120 can supply raw materials containing chloride ions into the water tank section 114. The chloride ion detection section 122 detects whether or not chloride ions are being supplied from the chloride ion supply section 120 to the water tank section 114 at preset intervals. An electrolytic section 130 is located inside the water tank section 114, and the electrolytic section 130 generates electrolytic water by electrolyzing the water containing chloride ions in the water tank section 114. The water supply section 140 can supply the electrolytic water stored in the water tank section 114.
[0070] In Figure 12(b), a water supply unit 140 is positioned between the water storage tank 110 and the electrolytic cell 112. The water supply unit 140 supplies chloride ion water from the water storage tank 110 to the electrolytic cell 112, thereby pushing out the electrolyzed water from the electrolytic cell 112 and supplying it from the fourth water channel 136.
[0071] According to this embodiment, the presence or absence of chloride ion supply is detected at pre-set intervals, and if supply is detected, electrolyzed water is generated and the electrolyzed water is sent, so that cleaning can be performed at the appropriate timing. Furthermore, because cleaning is performed at the appropriate timing, the accumulation of dirt can be effectively suppressed. Furthermore, because cleaning is performed at the appropriate timing, the generation of dirt due to bacterial growth can be prevented. In addition, since the valve 18 is closed until a predetermined time has elapsed after the electrolyzed water is generated, the cleaning power can be improved. Furthermore, if no supply is detected, a notification is sent to the notification unit, and water is sent without generating electrolyzed water, so cleaning can be performed even without a supply of chloride ions. Furthermore, if no supply is detected, a notification is sent to the notification unit, and electrolyzed water is generated and sent even without a supply of chloride ions, so cleaning can be performed even without a supply of chloride ions.
[0072] Furthermore, when the state changes from detecting no supply to detecting supply, a second electrolyzed water is generated and the second electrolyzed water is supplied, so by processing under conditions different from the steady state, dirt accumulated during the period without chloride ions can be effectively reduced. Also, since the time for generating the second electrolyzed water is made longer than the time for generating the first electrolyzed water, the concentration of the electrolyzed water can be increased. Also, since the concentration of the electrolyzed water is increased, dirt accumulated during the period without chloride ion supply can be reduced more effectively. Also, the more times the supply is not detected, the longer the time for generating the second electrolyzed water is made, so the longer the period without chloride ion supply, the higher the cleaning power can be. Also, since the current value for generating the second electrolyzed water is increased compared to the current value for generating the first electrolyzed water, the higher the concentration of the electrolyzed water can be. Also, since the more times the supply is not detected, the larger the current value for generating the second electrolyzed water is made, so the longer the period without chloride ion supply, the higher the cleaning power can be.
[0073] Furthermore, by making the closing time when the state changes from one where no supply is detected to one where supply is detected longer than the closing time before no supply is detected, the cleaning power can be increased. Also, the more times the supply is interrupted, the longer the closing time when the state changes from one where no supply is detected to one where supply is detected, so the longer the period without chloride ion supply, the higher the cleaning power can be. Also, by making the number of times the product is generated when the state changes from one where no supply is detected to one where supply is detected greater than the number of times it is generated before no supply is detected, the cleaning power can be increased. Also, the more times the supply is interrupted, the more times the product is generated when the state changes from one where no supply is detected to one where supply is detected, so the longer the period without chloride ion supply, the higher the cleaning power can be.
