Description

[Technical Field]

[0001] The present invention relates to an electrolyzed water generating device, and contributes to the technology of generating hypochlorous acid water by electrolysis. [Background technology]

[0002] Traditionally, hypochlorous acid water generated by electrolyzed water generators has been used in closed and semi-closed spaces where people gather, such as schools, hospitals, and commercial facilities, for sterilization, hygiene management, infection control, and BCP (business continuity planning).

[0003] The electrolyzed water generator generates chlorine gas by electrolyzing a raw chemical solution in an electrolytic cell, and mixes the chlorine gas into water supplied from a water supply system to generate slightly acidic electrolyzed water.

[0004] In addition, the electrolyzed water generating device described in Patent Document 1 comprises an electrolytic cell in which a pair of electrodes are arranged, a water-to-be-electrolyzed supply pipe that supplies water-to-be-electrolyzed containing an electrolyte to the electrolytic cell, and a power supply device that applies a DC voltage between the pair of electrodes.The water-to-be-electrolyzed supplied through the water-to-be-electrolyzed supply pipe is electrolyzed in the electrolytic cell by applying a DC voltage between the pair of electrodes by the power supply device, thereby generating electrolyzed water containing hypochlorous acid.The water-to-be-electrolyzed supply pipe is provided with a heating means for increasing the temperature of the water-to-be-electrolyzed.

[0005] Furthermore, the electrolyzed water generating device described in Patent Document 2 applies a DC voltage between a pair of electrodes from a power supply under control conditions where the current value detected by an ammeter is a preset electrolytic current corresponding to the required properties of the electrolyzed water, and generates electrolyzed water and pours it out from an outflow conduit. A drainage conduit is connected to the outflow conduit, and an outflow valve and a drainage valve are provided as switching means for switching the flow of electrolyzed water between the outflow conduit and the drainage conduit. When the set electrolytic current is detected by the ammeter, the outflow valve is controlled to open and the drainage valve is controlled to close, and when the set electrolytic current is not detected by the ammeter, the outflow valve is controlled to close and the drainage valve is controlled to open. [Prior art documents] [Patent documents]

[0006] [Patent Document 1] Patent Publication No. 2022-115302 [Patent Document 2] Patent Publication No. 2022-115299 Summary of the Invention [Problem to be solved by the invention]

[0007] In conventional electrolyzed water generators, such as those in Patent Document 1, the entire amount of raw water is heated. However, the amount of raw water is large, and the amount of energy consumed for heating is large, which raises concerns about the impact on costs, the environment, and safety.

[0008] Furthermore, as in Patent Document 2, when the dispensing valve is opened and the drain valve is closed when the set electrolysis current is detected by the ammeter, a waiting time occurs until the concentration of the electrolyzed water reaches the appropriate level before the extraction of electrolyzed water of the appropriate concentration can begin, resulting in a time loss from the start of electrolyzed water production to the completion of extraction of the electrolyzed water, which is a factor that reduces the time efficiency of extraction.

[0009] Furthermore, the remaining amount of electrolyte is detected by calculation from a theoretical value, i.e., the electrolysis operation time or the operation time of the electrolyte feed pump. However, since the amount of electrolyte consumed during electrolysis varies depending on the ambient temperature, there is a possibility that an error will occur between the theoretical value and the actual value, which may cause problems such as the electrolyte being depleted before a warning is issued or the warning being issued before the remaining amount reaches a predetermined amount.

[0010] Since the electrolyte is stored in a single tank, the amount remaining in the tank is the actual remaining amount of electrolyte. If there is a time lag between the issuance of the warning and replacement or replenishment, for example, due to not noticing the warning or being too busy to replace it, the electrolyte may run out and it may become impossible to extract electrolyzed water.

[0011] Drainage is by gravity flow, and installation is limited as it cannot be installed in places with a high head, such as where the drainage pipe is standing.

[0012] The present invention solves the above-mentioned problems and aims to provide an electrolyzed water generating device that always has electrolyzed water of the appropriate concentration ready when the user starts to take out electrolyzed water, eliminates waiting time until the concentration becomes appropriate when electrolyzed water is supplied, and eliminates time loss from the time the user starts the operation to supply electrolyzed water until electrolyzed water of the appropriate concentration is completely taken out, thereby improving the time efficiency of taking out the water. [Means for solving the problem]

[0013] In order to solve the above problems, the electrolyzed water generating device of the present invention comprises an electrolyzed water generating unit that generates electrolyzed water by mixing chlorine gas generated by electrolysis of an electrolyte into water supply, a water supply system that supplies water to the electrolyzed water generating unit, an electrolyte supply system that supplies electrolyte to the electrolyzed water generating unit, an electrolyzed water supply system that supplies the electrolyzed water generated in the electrolyzed water generating unit to an electrolyzed water outlet, a drainage system that leads to the outside of the device, a concentration adjustment drainage channel that connects the electrolyzed water supply system and the drainage system, a flow path switching unit that selectively switches and connects the electrolyzed water supply system to the electrolyzed water outlet and the concentration adjustment drainage channel, and a control unit that controls each part of the device. The control unit has an electrolyzed water supply operation function unit and a concentration adjustment operation function unit, and the electrolyzed water supply operation function unit performs supply operation control to generate electrolyzed water in the electrolyzed water generation unit and control the flow path switching unit to supply the electrolyzed water generated in the electrolyzed water generation unit to the electrolyzed water outlet during electrolyzed water service, and the concentration adjustment operation function unit performs adjustment operation control to generate electrolyzed water in the electrolyzed water generation unit and control the flow path switching unit to discharge the electrolyzed water generated in the electrolyzed water generation unit to the concentration adjustment drainage channel during idle time when the electrolyzed water supply operation function unit is not operating.

[0014] In the electrolyzed water generating device of the present invention, the concentration adjusting operation function unit is characterized by having an execution time setting unit that arbitrarily sets the execution time of the adjusting operation control.

[0015] In the electrolyzed water generating device of the present invention, the concentration adjusting operation function unit is characterized by having an operation timing setting unit that arbitrarily sets the operation timing of the adjusting operation control.

[0016] In the electrolyzed water generating apparatus of the present invention, the drainage system is characterized by having a drainage pump that forcibly drains the electrolyzed water.

[0017] The electrolyzed water generating device of the present invention is characterized in that it has a heating means for heating the electrolytic solution in the electrolyzed water generating unit or the electrolytic solution supply system.

[0018] In the electrolytic water generation device of the present invention, the electrolytic water generation unit is characterized by having an electrolytic cell that electrolyzes the electrolyte, having electrodes used for electrolysis within the electrolytic cell, and having at least one heating unit selected from the group consisting of an electrolytic cell heating unit that heats the electrolytic cell, an electrode heating unit that heats the electrodes, and a pipeline heating unit that heats the pipeline that supplies the electrolyte to the electrolytic cell.

[0019] In the electrolytic water generating device of the present invention, the electrolyte supply system is characterized by having an electrolyte storage section for storing the electrolyte, and at least one heating section, which is an electrolyte heating section for heating the electrolyte storage section and a pipeline heating section for heating the pipeline that supplies the electrolyte to the electrolytic cell. [Effects of the Invention]

[0020] As described above, according to the present invention, when electrolyzed water is being served, the electrolyzed water supply operation function unit performs supply operation control to supply the electrolyzed water generated in the electrolyzed water generation unit to the electrolyzed water outlet, and during idle time when the electrolyzed water supply operation function unit is not operating, the concentration adjustment operation function unit performs adjustment operation control to discharge the electrolyzed water generated in the electrolyzed water generation unit into the concentration adjustment drainage channel.As a result, there is no need to adjust the concentration of the electrolyzed water when serving electrolyzed water, and electrolyzed water of the appropriate concentration is ready when electrolyzed water service begins, so there is no waiting time for adjusting the concentration of the electrolyzed water, and there is no time loss from the start of electrolyzed water service to the completion of electrolyzed water removal, improving the time efficiency of removal.

[0021] In other words, by automatically generating and discharging electrolyzed water during idle times, when the water quality is unstable in the early stages of electrolysis, electrolyzed water of stable quality can always be provided when the electrolyzed water service is in progress.

[0022] The timing and amount of drainage during the adjustment operation control can be set as desired. For example, 10 AM at 10 L, or 2 hours after the last drain, 5 L. The user's draining operation, which is an external operation, can be set to interrupt so as not to interfere with the execution of the electrolyzed water service. This is done by setting the execution time of the adjustment operation control as desired in the execution time setting section of the concentration adjustment operation function section, and setting the operation time as desired in the operation time setting section of the concentration adjustment operation function section.

[0023] The drainage is forced out using a drainage pump, so the system can be installed in places where gravity flow is not possible, allowing for greater freedom in installation location.

[0024] Providing a function to heat the electrolyte improves the efficiency of electrolysis. This is achieved by providing an electrolytic cell heating unit that heats the electrolytic cell, an electrode heating unit that heats the electrodes, an electrolyte heating unit that heats the electrolyte reservoir, and a pipeline heating unit that heats the pipeline that supplies the electrolyte to the electrolytic cell. In other words, by heating the electrolyte that is supplied to the electrolytic water generation unit as electrolyte rather than heating the raw water that is supplied to the electrolytic water generation unit, the amount of material that needs to be heated is reduced, and electrolysis efficiency can be improved with less energy consumption, reducing the impact on costs, the environment (CO2), and safety (overheating due to malfunctions, etc.).

DETAILED DESCRIPTION OF THE INVENTION

[0026] An electrolyzed water generating device according to an embodiment of the present invention will be described below with reference to the drawings. Example 1 As shown in Figures 1 to 5, the electrolyzed water generating device 1 has, as its main components, an electrolyzed water generating unit 2, a water supply system 3, an electrolyte supply system 4, a control unit 5, an electrolyzed water supply system 6, an electrolyzed water extraction unit 7, and a drainage system 8.

[0027] In this embodiment, a plurality of electrolyzed water generation units 2 (two units in this example) are provided inside the housing 9. The electrolyzed water generation unit 2 has an electrode 22 inside an electrolytic cell 21, and in addition to the electrolytic cell 21, has a chemical pump 23, and is also composed of a pressure reducing valve, a solenoid valve, a flow meter, a check valve, a trap waterway, etc. (not shown).

[0028] As shown in Fig. 4 as an example, the electrolytic cell 21 has an air mixing section 25 connected to the electrolytic water discharge passage 24. Then, hydrochloric acid in the raw chemical solution, which is the electrolyte, is electrolyzed to generate chlorine gas G, and the chlorine gas G is mixed into the feed water flowing through the pipeline of the water supply system 3 in the air mixing section 25 from an opening 26 of the electrolytic cell 21, to obtain slightly acidic electrolyzed water (hypochlorous acid water). The slightly acidic electrolyzed water here is an aqueous solution whose main active ingredient is hypochlorous acid (HClO), with a pH of 5.0-6.5 and an effective chlorine concentration of 10-80 mg / kg.

[0029] The water supply system 3 has, in order from upstream to downstream, a ball valve 31, a strainer 32, a check valve 33, and an emergency shut-off valve 34 in the flow path that supplies water from the water supply source 10 to each electrolyzed water generation unit 2, as well as a water receiving tank 35 and a booster pump 36. The downstream pipe leading to the discharge port of the booster pump 36 is connected to the inlet port of a first three-way valve 38 via a check valve 37, and the downstream pipe leading to one outlet port of the first three-way valve 38 branches, and each of the branch pipes is connected to each of the electrolyzed water generation units 2 via a constant flow valve 39 and a constant flow valve 40. The downstream pipe leading to the other outlet port of the first three-way valve 38 is connected to the drainage system 8. As an alternative pipe configuration, a pair of constant flow valves with different set flow rates can be switchably arranged in each of the branch pipes.

[0030] The electrolyte supply system 4 supplies hydrochloric acid, the raw chemical solution stored in a replaceable chemical cartridge 41, to the chemical pumps 23 of both electrolyzed water generation units 2 via a permanent chemical tank 42. The chemical cartridge 41 and the chemical tank 42 form an electrolyte storage section that stores the raw chemical solution. The raw chemical solution from the chemical cartridge 41 is supplied to the chemical tank 42 by a chemical supply pump 43, and the raw chemical solution from the chemical tank 42 is pumped up by the chemical pumps 23 of each electrolyzed water generation unit 2. The chemical tank 42 has an upper limit sensor 44 for the upper liquid level and a lower limit sensor 45 for the lower liquid level. When the lower limit sensor 45 turns OFF, the chemical supply pump 43 starts, and when the lower limit sensor 45 turns ON, the chemical supply pump 43 stops. The upper limit sensor 44 is a fail-safe that causes an error stop if the liquid level is abnormally high. The chemical cartridge 41 and the chemical tank 42 are placed on a chemical drain pan 47 equipped with a water leakage sensor 46 .

[0031] The electrolyzed water supply system 6 supplies electrolyzed water generated in the electrolyzed water generation unit 2 to multiple, here two, electrolyzed water extraction units 7 via a second three-way valve 61 and a third three-way valve 62, which form a flow path switching unit. The downstream pipes leading to the electrolyzed water discharge paths 24 of each electrolyzed water generation unit 2 join together and then connect to the inlet port of the third three-way valve 61. One outlet port of the second three-way valve 61 is connected to the inlet port of the third three-way valve 62, and the other outlet port of the second three-way valve 61 is connected to the drainage system 8 via a concentration adjustment drainage path 63.

[0032] Each of the electrolyzed water outlet units 7 has storage units 71, 72 for storing containers 13, 14 of different capacities, and has electrolyzed water outlets 73, 74 for discharging electrolyzed water into the storage units 71, 72. Here, a small-capacity (2 L) container 13 is stored in the storage unit 71 of the upper electrolyzed water outlet unit 7, and a large-capacity (10 L) container 14 is stored in the storage unit 72 of the lower electrolyzed water outlet unit 7. A downstream pipe leading to one outlet port of the third three-way valve 62 is connected to the electrolyzed water outlet 73 of the small-capacity container 13, and a downstream pipe leading to the other outlet port of the third three-way valve 62 is connected to the electrolyzed water outlet 74 of the large-capacity container 14.

[0033] The electrolyzed water extraction section 7 has a door lock 75 and an upper drain pan 76 in the upper storage section 71, and a door lock 75 and a lower drain pan 77 in the lower storage section 72, and the lower drain pan 77 is equipped with an upper water level sensor 78, a lower water level sensor 79, and a set water level sensor 80.

[0034] The downstream pipe leading to the upper drain pan 76 is connected to a lower drain pan 77, and the lower drain pan 77 is connected to a drainage system 8 and a drain valve 81.

[0035] In addition, a downstream pipe continuing from the other outlet port of the first three-way valve 38 is connected to a lower drain pan 77, a concentration adjustment drainage path 63 leading to the other outlet port of the second three-way valve 61 is connected to the lower drain pan 77, and an overflow pipe 351 of the water receiving tank 35 is connected to the lower drain pan 77. The drainage system 8 has a drainage pump 82, and the downstream pipe leading to the discharge port of the drainage pump 82 is connected to a drainage port 84 via a check valve 83, and the downstream pipe of the drainage pump 82 is connected to the lower drain pan 77 via a vacuum breaker 85.

[0036] In this embodiment, the concentration adjustment drainage channel 63 leading to the other outlet port of the second three-way valve 61 is connected to the lower drain pan 77, but it can also be connected to the drainage system 8 downstream of the drainage pump 82.

[0037] Each of the electrolyzed water outlet units 7 has a door 91, 92, and is equipped with various sensors for checking whether the doors 91, 92 are open or closed, whether a container is present, and whether the doors are locked or unlocked.

[0038] The control unit 5 has an electrolyzed water supply operation function unit 51 and a concentration adjustment operation function unit 52 configured internally by circuits or programs, and has a selection operation unit 53 (2 L, 10 L, cancel, etc.) on its outer surface. When electrolyzed water service is performed to supply electrolyzed water to the electrolyzed water extraction unit 7, the electrolyzed water supply operation function unit 51 starts both electrolyzed water generation units 2 to generate electrolyzed water, and controls the second three-way valve 61 and the third three-way valve 62 of the flow path switching unit to perform supply operation control to supply the electrolyzed water generated in the electrolyzed water generation units 2 to the electrolyzed water extraction port.

[0039] During idle times when the electrolytic water supply operation function unit 51 is not operating, the concentration adjustment operation function unit 52 activates both electrolytic water generation units 2 to generate electrolytic water, and controls the second three-way valve 61 of the flow path switching unit to discharge the electrolytic water generated in the electrolytic water generation unit 2 into the drainage system 8 via the concentration adjustment drainage path 63.

[0040] The concentration adjustment operation function unit 52 has as its maintenance program an execution time setting unit 54 that arbitrarily sets the execution time of the adjustment operation control and an operation timing setting unit 55 that arbitrarily sets the operation timing of the adjustment operation control, and the execution time setting unit 54 and the operation timing setting unit 55 are controlled by operating a touch panel or the like.

[0041] The operation of the above configuration will be described below. The user operates the selection operation unit 53 of the control unit 5 to select the electrolyzed water extraction unit 7 to be supplied.

[0042] The electrolyzed water supply operation function unit 51 of the control unit 5 supplies water from the water supply system 3 to both electrolyzed water generation units 2 using the pressure pump 36 during electrolyzed water service, and supplies the electrolytic solution supplied from the electrolyte supply system 4 to the electrolytic cell 21 using the chemical pump 23 to generate electrolyzed water.The electrolyzed water generated in the electrolyzed water generation unit 2 is supplied to the electrolyzed water outlets 73, 74 of the selected electrolyzed water extraction unit 7, and a fixed amount of electrolyzed water set for each container 13, 14 of the selected electrolyzed water extraction unit 7 is supplied with each supply operation.

[0043] For example, up to 2 L of electrolyzed water is supplied each time from the electrolyzed water outlet 73 to the container 13 stored in the upper storage section 71, and up to 10 L of electrolyzed water is supplied each time from the electrolyzed water outlet 74 to the container 14 stored in the lower storage section 72.

[0044] That is, when the user requests the supply of electrolyzed water to the upper storage section 71 using the selection operation section 53, the electrolyzed water supply operation function section 51 turns OFF the door lock 75 of the corresponding storage section 71. The user opens the door, places the container 13, and closes the door. The electrolyzed water supply operation function section 51 turns ON the door lock 75, starts supplying electrolyzed water, and supplies it to the electrolyzed water outlet 73 located in the upper storage section 71 through the second three-way valve 61 and the third three-way valve 62.

[0045] Furthermore, when the user requests the supply of electrolyzed water to the lower storage section 72 using the selection operation section 53, the electrolyzed water supply operation function section 51 turns OFF the door lock 75 of the corresponding storage section 72. The user opens the door, places the container 14, and closes the door. The electrolyzed water supply operation function section 51 turns ON the door lock 75, starts supplying electrolyzed water, and supplies it to the electrolyzed water outlet 74 located in the lower storage section 72 through the second three-way valve 61 and the third three-way valve 62.

[0046] In this way, by providing multiple electrolyzed water extraction units 7 each having electrolyzed water extraction outlets 73, 74 for discharging electrolyzed water, selecting the electrolyzed water extraction unit 7 to which the electrolyzed water is to be supplied, and supplying a set amount of electrolyzed water for each electrolyzed water extraction unit 7, it is possible to selectively respond to multiple consumption needs for electrolyzed water.

[0047] The control unit 5 periodically or irregularly performs adjustment operation control during idle times when the electrolyzed water supply operation function unit 51 is not operating, by activating the concentration adjustment operation function unit 52 to generate electrolyzed water in both electrolyzed water generation units 2, and by controlling the second three-way valve 61 of the flow path switching unit to discharge the electrolyzed water generated in both electrolyzed water generation units 2 into the drainage system 8 through the concentration adjustment drainage path 63.

[0048] By performing this adjustment operation control, there is no need to adjust the concentration of electrolyzed water when it is being served, and electrolyzed water of the appropriate concentration is already prepared when the electrolyzed water service begins, so there is no waiting time for the concentration of the electrolyzed water to be adjusted, and there is no time loss from the start of the electrolyzed water service until the electrolyzed water is completely taken out, improving the time efficiency of the water being taken out.

[0049] In other words, by automatically generating and discharging electrolyzed water during idle times, when the water quality is unstable in the early stages of electrolysis, electrolyzed water of stable quality can always be provided when the electrolyzed water service is in progress.

[0050] The timing of starting the concentration adjustment operation function unit 52, that is, the timing and amount of drainage during adjustment operation control, can be set arbitrarily. For example, 10 L of water can be generated and drained at 10 AM when operation starts first thing in the morning. Or, 5 L can be generated and drained irregularly when two hours have passed since the last withdrawal. However, the user's withdrawal operation, which is an external operation, can be set to be interruptible so as not to interfere with the execution of the electrolyzed water service.

[0051] This is done by arbitrarily setting the execution time of the adjustment operation control in the execution time setting unit 54 of the concentration adjustment operation function unit 52, and arbitrarily setting the operation timing in the operation timing setting unit of the concentration adjustment operation function unit 52.

[0052] Furthermore, the control unit 5 periodically or irregularly starts the drain pump 82, which drains wastewater accumulated in the drain pan 76 at the bottom out of the machine through the drainage system 8 and the drain outlet 84. By forcibly draining water using this drain pump 82, the machine can be installed in places where water cannot be drained by gravity, which increases the flexibility of the installation location. Example 2 6, it is also possible to provide a heating means for heating the electrolytic solution in the electrolytic water production unit 2 or the electrolytic solution supply system 4. Suitable heating means include a surface heater and a wrap heater (ribbon, string, etc.).

[0053] For example, the electrolyzed water production unit 2 is provided with an electrolytic cell heating section 27a that heats the electrolytic cell 21, an electrode heating section 27b that heats the electrodes 22, or a pipeline heating section 27c that heats the pipeline that supplies the electrolytic solution to the electrolytic cell 21. The electrolyte solution supply system 4 is provided with an electrolyte solution heating section 27d that heats the chemical solution cartridge 41 and chemical solution tank 42 that form the electrolyte solution storage section, or a pipeline heating section 27e that heats the pipeline that supplies the electrolytic solution to the electrolytic cell 21. It is also possible to selectively provide at least one of the heating sections.

[0054] In this way, by heating the electrolyte supplied to the electrolytic water generation unit 21 as an electrolytic solution rather than heating the raw water supplied to the electrolytic water generation unit 2, the amount of material to be heated is small, and the electrolysis efficiency can be increased with less energy consumption, thereby reducing the impact on costs, the environment (CO2), and safety (overheating due to malfunctions, etc.).
