Description

This invention relates to an electrolytic water generating device, and contributes to the technology of generating hypochlorous acid water through electrolysis.

Traditionally, hypochlorous acid water generated by electrolytic 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).

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

The electrolytic water generating device described in Patent Document 1 includes 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 unit that applies a DC voltage between the pair of electrodes. The water-to-be-electrolyzed supply pipe is supplied with a DC voltage between the pair of electrodes by the power supply unit in the electrolytic cell, whereby electrolytic water containing hypochlorous acid is generated by electrolyzing the water-to-be-electrolyzed supply pipe. The water-to-be-electrolyzed supply pipe is provided with a heating means for increasing the temperature of the water-to-be-electrolyzed.

The electrolytic 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 electrolytic water, and generates electrolytic water and pours it out from an outlet pipe. A drain pipe connected to the outlet pipe, and an outlet valve and a drain valve are provided as switching means for switching the flow of electrolytic water between the outlet pipe and the drain pipe. When the ammeter detects the set electrolytic current, the outlet valve is controlled to open and the drain valve is controlled to close, and when the ammeter does not detect the set electrolytic current, the outlet valve is controlled to close and the drain valve is controlled to open.

In conventional electrolytic water generating devices, such as those described in Patent Document 1, the entire amount of raw water is heated. However, the amount of raw water is large, and a large amount of energy is consumed to heat it, raising concerns about the impact on costs, the environment, and safety.

In addition, 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 electrolyzed water becomes appropriate 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 in reducing the time efficiency of extraction.

In addition, the remaining amount of electrolyte is detected by calculation from a theoretical value, i.e., from the electrolysis operation time or the operation time of the electrolyte delivery pump. However, since the amount of electrolyte consumed during electrolysis varies depending on the environmental temperature, an error occurs 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 specified amount.

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

Drainage is by gravity flow, so installation locations are limited as it cannot be installed in places with a high head, such as where the drainage pipes are standing.

The present invention aims to solve the above-mentioned problems and provide an electrolytic water generating device that can replenish the electrolyte supply while continuing to operate the electrolytic water generating unit for a certain period of time even if the electrolyte supply runs out.

In order to solve the above problems, the electrolytic water generating device of the present invention includes an electrolytic water generating unit that generates electrolytic water by mixing chlorine gas generated by electrolysis of an electrolytic solution into water supply, a water supply system that supplies water to the electrolytic water generating unit, and an electrolytic solution supply system that supplies the electrolytic solution to the electrolytic water generating unit.
The device is equipped with a control unit that controls each part, and the electrolyte supply system has a replaceable chemical cartridge as a supply source, a buffer unit arranged in the path that supplies electrolyte from the chemical cartridge to the electrolytic water generation unit, and a measuring unit that actually measures the actual remaining amount of electrolyte in the chemical cartridge by measuring the liquid level or weight, and the electrolytic water generation unit has an electrolytic cell and a chemical pump that supplies electrolyte to the electrolytic cell, and the chemical pump supplies electrolyte to the electrolytic cell through the buffer unit, and the control unit issues an alarm when the measurement value of the measuring unit is below a set value.

The electrolytic water generating device of the present invention is characterized in that the electrolyte supply system has a permanent chemical tank that serves as a buffer section, and a chemical supply pump that supplies electrolyte from the chemical cartridge to the chemical tank.

The electrolytic water generating device of the present invention is also characterized in that the electrolyte supply system is made up of a flexible spiral tube in which the buffer section has a spirally arranged pipeline to increase the length of the pipeline.

The electrolytic water generating device of the present invention is also characterized in that the electrolyte supply system is made up of a flexible large-diameter tube in the buffer section, which has a redundant pipe diameter.

As described above, according to the present invention, by supplying the electrolyte to the electrolytic water generating unit through the buffer section, a certain amount of electrolyte remains in the buffer section even when the electrolyte supply source is depleted.

As a result, the electrolytic water generating unit can continue to operate for a certain period of time corresponding to the amount of electrolyte remaining in the buffer section, while the supply source chemical cartridge can be replaced during this time, providing a grace period for replenishing the electrolyte supply source.

Since the spiral tube and large diameter tube are flexible, there are fewer spatial constraints in arranging the buffer section, allowing greater freedom and making effective use of the internal space of the device as a whole. In addition, an electrolyte supply pump is no longer necessary, simplifying the device configuration.

FIG. 2 is a schematic diagram showing a main part of the electrolytic water generating device according to the embodiment; FIG. 2 is a schematic diagram showing a control unit of the electrolytic water generating device according to the embodiment; FIG. 13 is a schematic diagram showing a buffer unit according to another embodiment of the present invention; FIG. 13 is a schematic diagram showing a buffer unit according to still another embodiment of the present invention;

The electrolytic water generating device according to the embodiment of the present invention will be described below with reference to the drawings.

As shown in Figures 1 to 5, the electrolytic water generating device 1 has, as its main components, an electrolytic water generating unit 2, a water supply system 3, an electrolyte supply system 4, a control unit 5, an electrolytic water supply system 6, an electrolytic water extraction unit 7, and a drainage system 8.

In this embodiment, the housing 9 contains multiple electrolytic water generation units 2, two in this example. The electrolytic water generation unit 2 contains an electrode 22 inside an electrolytic cell 21, and in addition to the electrolytic cell 21, contains a chemical pump 23, and is composed of a pressure reducing valve, a solenoid valve, a flow meter, a check valve, a trap waterway, etc., which are not shown.

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, the hydrochloric acid in the raw chemical solution, which is the electrolyte, is electrolyzed to generate chlorine gas G, and in the air mixing section 25, the chlorine gas G is mixed into the feed water flowing through the pipeline of the water supply system 3 from an opening 26 of the electrolytic cell 21, to obtain slightly acidic electrolytic water (hypochlorous acid water). The slightly acidic electrolytic 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.

The water supply system 3 has, in sequence from upstream to downstream, a ball valve 31, a strainer 32, a check valve 33, and an emergency shutoff valve 34 in the flow path that supplies water from the water supply source 10 to each electrolytic water generation unit 2, and further has a water receiving tank 35 and a pressure pump 36. The downstream pipe following the discharge port of the pressure pump 36 is connected to the inlet port of the first three-way valve 38 via a check valve 37, and the downstream pipe following one outlet port of the first three-way valve 38 branches, and each of the branch pipes is connected to each of the electrolytic water generation units 2 via constant flow valves 39 and 40. The downstream pipe following the other outlet port of the first three-way valve 38 is connected to the drainage system 8. As another pipe configuration, a pipe configuration in which a pair of constant flow valves with different set flow rates are switchably arranged in each branch pipe is also possible.

The electrolyte supply system 4 has a replaceable chemical cartridge 41 as a supply source, and a buffer section arranged in the path that supplies electrolyte from the chemical cartridge 41 to the electrolytic water generation unit 2, where the buffer section is made up of a permanent chemical tank 42.

The electrolyte supply system 4 supplies hydrochloric acid, which is the raw chemical solution that is the electrolyte stored in the replaceable chemical solution cartridge 41, which is the supply source, to the chemical solution pumps 23 of both electrolytic water generating units 2 via the chemical solution tank 42, which is the buffer section. The chemical solution cartridge 41 and the chemical solution tank 42 form an electrolyte solution storage section that stores the raw chemical solution.

The raw chemical liquid from the chemical cartridge 41 is supplied to the chemical tank 42 by the chemical supply pump 43, and the raw chemical liquid from the chemical tank 42 is sucked up by the chemical pump 23 of each electrolytic 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 is OFF, the chemical supply pump 43 starts, and when the lower limit sensor 45 is ON, the chemical supply pump 43 stops. The upper limit sensor 44 is a fail-safe for stopping the operation due to an error at an abnormally high liquid level. The chemical cartridge 41 and the chemical tank 42 are placed on a chemical drain pan 47 equipped with a water leakage sensor 46.

The stand 400 on which the drug solution cartridge 41 is placed is provided with a measuring unit 401 that actually measures the actual remaining amount of electrolyte remaining inside the drug solution cartridge 41. Here, the measuring unit 401 is made up of a non-contact liquid level measuring unit 402, but it is also possible to actually measure by weight measurement. The liquid level measuring unit 402 is a non-contact type proximity sensor, level sensor, etc., and is capable of measuring the liquid level at multiple detection positions; here, the liquid level is measured at the upper limit position 403, the intermediate position 404, and the lower limit position 405.

In other words, when the amount of electrolyte inside the drug solution cartridge 41 decreases and the liquid level reaches the level of the lower limit position 405, the control unit 5 determines that the amount of electrolyte in the drug solution cartridge 41, which is the supply source, is so small that the drug solution supply pump 43 can no longer adequately supply electrolyte.

The electrolytic water supply system 6 supplies electrolytic water generated in the electrolytic water generation unit 2 to multiple, here two, electrolytic water extraction units 7 via a second three-way valve 61 and a third three-way valve 62 that form a flow path switching unit. The downstream pipelines leading to the electrolytic water discharge paths 24 of each electrolytic water generation unit 2 merge and are then connected 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.

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

The electrolytic 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. The lower drain pan 77 is equipped with an upper limit water level sensor 78, a lower limit water level sensor 79, and a set water level sensor 80.

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

In addition, a downstream pipe continuing to 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 drain port 84 via a check valve 83, and the middle of the pipe downstream of the drainage pump 82 is connected to the lower drain pan 77 via a vacuum breaker 85.

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.

Each of the electrolytic water extraction units 7 has doors 91, 92, and is equipped with various sensors that check whether the doors 91, 92 are open or closed, whether a container is present, and whether the doors are locked or unlocked.

The control unit 5 has an electrolytic 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 (2L, 10L, cancel, etc.) on the outer surface. When electrolytic water service is performed to supply electrolytic water to the electrolytic water extraction unit 7, the electrolytic water supply operation function unit 51 starts both electrolytic water generation units 2 to generate electrolytic 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 electrolytic water generated in the electrolytic water generation unit 2 to the electrolytic water extraction port.

During idle times when the electrolytic water supply operation function unit 51 is not in operation, the concentration adjustment operation function unit 52 starts 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 units 2 into the drainage system 8 via the concentration adjustment drainage channel 63.

The concentration adjustment operation function unit 52 has 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 as a maintenance program, and the execution time setting unit 54 and the operation timing setting unit 55 are controlled by operating a touch panel or the like.

The control unit 5 further includes an alarm unit 56. When the liquid level measured by the liquid level measuring unit 402 reaches the level of the lower limit position 405, the control unit 5 determines that the amount of electrolyte in the chemical solution cartridge 41, which is the supply source, is low and that the chemical solution supply pump 43 can no longer supply electrolyte sufficiently. The alarm unit 56 issues an alarm to notify that the chemical solution cartridge 41, which is the supply source of electrolyte, has run out.

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

When providing electrolytic water service, the electrolytic water supply operation function unit 51 of the control unit 5 supplies water from the water supply system 3 to the electrolytic water generating unit 2 corresponding to any selected electrolytic water extraction unit 7 using the pressure pump 36, supplies the electrolytic solution supplied from the electrolyte supply system 4 to the electrolytic cell 21 using the electrolyte pump 23 to generate electrolytic water, and supplies the electrolytic water generated by the electrolytic water generating unit 2 to the electrolytic water outlets 73, 74 of the selected electrolytic water extraction unit 7, supplying a fixed amount of electrolytic water set for each container 13, 14 of the selected electrolytic water extraction unit 7 with each supply operation.

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.

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 the supply, and supplies electrolyzed water 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.

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 the supply, and supplies electrolyzed water 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.

In this way, by providing multiple electrolyzed water extraction units 7 each having an electrolyzed water outlet 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, multiple consumption needs for electrolyzed water can be selectively met.

In addition, by selectively switching between electrolyzed water generating units 2 with different water supply volumes, electrolyzed water with different effective chlorine concentrations can be selectively supplied according to the application.

The control unit 5 periodically or irregularly performs adjustment operation control during idle times when the electrolytic water supply operation function unit 51 is not in operation, activating the concentration adjustment operation function unit 52 to generate electrolytic water in both electrolytic water generation units 2, 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 through the concentration adjustment drainage channel 63 to the drainage system 8.

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 prepared when electrolyzed water service begins, so there is no waiting time for the concentration of electrolyzed water to be adjusted, and there is no time lost from the start of electrolyzed water service until the electrolyzed water is taken out, improving the time efficiency of the water being taken out.

In other words, by automatically generating and draining electrolyzed water during idle times, when the water quality is unstable at the beginning of the electrolysis process, electrolyzed water of stable quality can always be provided when the electrolyzed water service is started.

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

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.

In addition, the control unit 5 periodically or irregularly starts the drain pump 82, which drains wastewater accumulated in the lower drain pan 76 through the drainage system 8 and out of the machine from 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, allowing for greater freedom in the installation location.

When the liquid level measured by the liquid level measuring unit 402 reaches the level of the lower limit position 405, the control unit 5 determines that the amount of electrolyte in the supply source, the chemical solution cartridge 41, is so small that the chemical solution supply pump 43 can no longer adequately supply electrolyte, and the alarm unit 56 sounds to notify that the remaining amount of electrolyte in the chemical solution cartridge 41, which is the supply source, has run out.

The electrolyte supply system 4 supplies the electrolyte to the electrolytic water generating unit 2 through the buffer section's chemical tank 42, so that even when the electrolyte in the supply source's chemical cartridge 41 runs out, a certain amount of electrolyte remains in the buffer section's chemical tank 42.

As a result, the electrolytic water generating unit can continue to operate for a certain period of time corresponding to the amount of electrolyte remaining in the chemical tank 42, while the chemical cartridge 41, which is the supply source, can be replaced during this period, providing a grace period for replenishing the electrolyte supply source.

Here, the buffer section is made up of a chemical tank 42, so that a large amount of electrolyte can be stored, and the operation of the electrolytic water generation unit can be continued for a grace period of, for example, several weeks, even after the electrolyte supply source runs out.

As shown in FIG. 6, the buffer section of the electrolyte supply system 4 can be configured as a spiral tube 421 in which the pipeline is arranged in a spiral shape to increase the pipeline length.

In this case, since the spiral tube 421 is flexible, there are fewer spatial constraints in arranging the buffer section, allowing greater freedom, and the internal space of the device as a whole can be used effectively. In addition, the electrolyte supply pump 43 is no longer necessary, simplifying the device configuration.

As shown in FIG. 7, the electrolyte supply system can also be configured with a large-diameter tube 422 in which the buffer section has a redundant pipe diameter.

Even in this case, the large diameter tube 422 is flexible, so there are fewer spatial constraints in arranging the buffer section, allowing greater freedom and making effective use of the internal space of the device as a whole. In addition, the electrolyte supply pump 43 is no longer necessary, simplifying the device configuration.
