Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electrolyzed water generator for, for example, disinfection and sterilization (sterilization). Preferably, the present invention relates to an electrolyzed water generator used for care such as disinfection in the oral cavity.

[0002]

2. Description of the Related Art For example, in the fields of agriculture and food,
Electrolyzed water generated by electrolysis is useful,
Generally known. This electrolyzed water has excellent disinfecting and disinfecting effects and is highly safe. Therefore, in order to prevent food poisoning in ordinary households, household goods such as kitchenware, baby goods, toys, cloth towels, furniture, toilets, bathrooms, etc. ,
It has begun to be applied to disinfection and sanitization of rooms such as bedrooms and living rooms.

[0003] In addition, it has begun to be used for disinfection and disinfection of the human body, particularly for washing and disinfecting the fingers. It has been studied to use it for sterilization and disinfection of percutaneous openings, stomas (prosthesis), anus, etc. Especially in the field of oral care, conventional disinfectants use drugs that are toxic to the human body, such as popidone iodine, oxidol, and sodium hypochlorite. Is a disinfectant that has high bactericidal activity and low toxicity, and is gentle to the human body and the environment, so its use is expanding.

[0004] Such an apparatus for producing electrolyzed water is directly connected to a water supply pipe, and is used for mixing a concentrated solution of the water to be electrolyzed and tap water to produce a large stationary apparatus or several hundreds of electrolyzed water.
There are known small batch-type ones in which a container of about cc is placed and an electrode is incorporated in this container to generate electrolyzed water. However, large-sized devices for stationary use have to be transferred to another container and used once in the medical field, which is troublesome. In addition, a small batch-type electrolyzed water generator must be prepared in a specified amount even if the amount used is small.For electrolyzed water that changes over time during storage, extra electrolyzed water can be discarded. Many. Also, when one or more batches of electrolyzed water are desired to be used, they must be prepared a plurality of times, which is inconvenient.

[0005] In addition, the electrode used in the conventional batch system has a smaller electrode area in contact with the amount of water to be electrolyzed in the electrolyzer, has lower electrolysis efficiency, and has a longer electrolysis time than an apparatus for continuously producing electrolyzed water. Cost. In order to obtain effective electrolyzed water in a short time, the electrodes must be enlarged.

[0006] In the case of oral care, since the target for injecting acidic water is in the mouth, the injection nozzle must be as light and small as possible, and a pump, an electrolysis section, a power supply section, and a storage of electrolyzed water. When the main body such as the unit and the injection nozzle are integrated, the operability is significantly reduced. For this reason, it is preferable that the injection nozzle is connected to the main body via the liquid feeding tube.

Further, a system for injecting electrolyzed water in synchronism with electrolysis in order to always supply fresh electrolyzed water is preferable. However, when a small pump is used, the load pressure on the pump changes by moving up and down the liquid feeding tube. Then, the flow rate changes. If the flow rate of the water to be electrolyzed flowing into the electrolysis unit changes, there is a problem that the effective chlorine concentration changes under a constant electrolysis current.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a light-weight and small-sized electrolyzed water generating apparatus, and the electrolyzed water generated even when a load pressure on a pump changes and a flow rate changes.

[0020]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an electrolyzed water generating apparatus according to the present invention will be described based on a preferred embodiment shown in the accompanying drawings. The electrolyzed water generating apparatus 1 of the present invention shown in FIG.
It consists of a tube 4.

The main body 2 has an electrolyzed water storage 5 for storing electrolyzed water, an electrolyzer 6 for electrolyzing the electrolyzed water to generate electrolyzed water, and an electrolyzed water storage for temporarily storing electrolyzed water. Part 8
And a tube 93, a solenoid 72, a constricted portion 73, a pump 93 for feeding stored electrolytic water, and a tube 91,
92.

The electrolysis section 6 has electrodes 61 and 62 which serve as an anode and a cathode, respectively, and perform electrolysis of the electrolyzed water passing between the electrodes. A tube 71 is provided downstream of the electrolytic section 6.
Are connected to the electrolyzed water storage unit 8 via the constriction 73. Here, the liquid flow path of the electrolytic unit 6,
The tube 71 and the constriction 73 form a first channel.
Further, the constricted portion 73 uses the head between the electrolyzed water storage portion 5 and the electrolyzed water storage portion 8 to make the electrolyzed water flow at a suitable speed when performing electrolysis while flowing the electrolyzed water. It also has functions. The solenoid 72 is provided with a tube 7 so that water to be electrolyzed flows through the electrolysis section in response to the supply of electricity to the electrolysis section.
1 is opened and closed. The solenoid 72 forms an electrolyzed water control unit.

The electrolyzed water storage section 8 has an electrolyzed water inflow section 83,
An electrolyzed water outflow portion 84 and an electrolyzed water sampling portion 82 are provided. A tube 91 is connected to the electrolytic water outflow portion 84 and the pump 9
3. The tube 92 is subsequently connected. Tube 9
A tube 4 is connected to a downstream side of the tube 2, and an injection unit 3 is connected to a tip of the tube 4. The liquid flow path of the pump 93 (not shown), the tubes 91, 92, and 4 and the electrolyzed water flow section of the injection section 3 form a second water path. The injection unit 3 has an injection nozzle 31 and a switch 32.

According to the present invention, the flow rate of the electrolyzed water flowing through the electrolysis section 6 and the flow rate of the electrolyzed water discharged from the injection nozzle 31 are defined as follows.
Since it has the electrolyzed water control means and the electrolyzed water control means which are controlled separately and independently, it is possible to electrolyze the electrolyzed water under constant electrolysis conditions even if it has a long second water path represented by the tube 4. As a result, it is possible to obtain electrolyzed water of a certain property and to apply the electrolyzed water to a narrow space such as the oral cavity.

Hereinafter, these will be described in detail. The electrolyzed water reservoir 5 may be hard or soft.
The capacity is 100 to 1500 in consideration of miniaturization of the device.
ml is preferable, and 250-1000 ml is more preferable.
A predetermined amount of electrolyzed water is stored inside the electrolyzed water storage unit 5.

The water to be electrolyzed used in the present invention is, for example, an aqueous solution in which an electrolyte such as sodium chloride, potassium chloride or magnesium chloride is dissolved, and sodium chloride is particularly preferable in consideration of safety for the human body. The concentration of the electrolyte in the water to be electrolyzed is preferably, for example, 0.2 to 1 w / v% for sodium chloride, and 0.3 to 0.9 w / v.
% Is more preferred. When the electrolyte concentration is less than 0.2 w / v% as sodium chloride, the electrolysis efficiency is reduced, and a device for continuously generating electrolyzed water with a small applied voltage is required to generate a sufficient effective chlorine concentration. Requires the flow rate to be reduced, which takes time to produce. If the concentration of sodium chloride exceeds 1% w / v, the amount of salt precipitated by drying after use of electrolytic water increases.

In order to keep the pH of the electrolyzed water generated by electrolysis within a suitable range, it is preferable to add an acid for pH adjustment to the water to be electrolyzed in advance. Acids for pH adjustment include inorganic acids such as hydrochloric acid and sulfuric acid, citric acid, ascorbic acid,
Organic acids such as acetic acid and succinic acid can be mentioned, but succinic acid is preferable in consideration of pH stability in a range of pH 3 to 7 of generated electrolyzed water, safety to a human body, and temporal stability of effective chlorine concentration. . The succinic acid concentration may be appropriately set according to the effective chlorine concentration of the generated electrolytic water,
For example, when producing 50 ppm of electrolyzed water, about 0.0
Addition of 1% w / v succinic acid stabilizes the pH in the range of 3-7.

The electrolyzed water is supplied from the electrolyzed water reservoir 5 to the electrolyzer 6.
As the electrolyzed water control means for feeding the electrolyzed water, a liquid feed pump may be installed. However, when the electrolyzed water storage portion and the electrolyzed water storage portion can be fed by a head, the liquid is sent by the head. It is more preferable because it is smaller and lighter. The liquid sending flow rate due to the head can be controlled by providing a portion having a small orifice diameter in the middle of the first water channel. Further, even when a pump is used as the electrolyzed water control means, the condition of the flow path from the electrolyzed water reservoir 5 to the electrolyzed water inlet 83 is constant, and the flow rate of the electrolyzed water in the electrolyzer 6 is controlled. A simple pump can be used to keep it constant.

The electrolysis section 6 is formed in the middle of a first water channel connecting the electrolyzed water storage section 5 and the electrolyzed water storage section 8, and is provided with an electrode pair 61, 62 composed of an anode and a cathode disposed opposite to each other. It is composed of a pair of energizing circuits. The electrolytic unit 6 is a non-diaphragm electrolytic cell in which no diaphragm is interposed between the anode and the cathode.
Thereby, the configuration of the apparatus can be simplified as compared with the case where an electrolytic cell having a diaphragm is used, and the required amount of electrolyzed water can be generated with a smaller amount of electrolyzed water because no alkaline waste liquid is generated. There is.

The material of the anode and the cathode may be, for example, a metal plate made of titanium and plated with platinum, but is not limited to this configuration. The distance between the anode and the cathode is preferably 0.2 to 5 mm, and 0.3 to 3 mm.
Is more preferred. If the distance between the electrodes is less than 0.2 mm, the gas generated from the electrodes will block the flow path, making it difficult for the water to be electrolyzed to flow. On the other hand, if it exceeds 5 mm, the electrolysis efficiency is lowered, and the concentration of the produced effective chlorine is lowered. The effective area of the electrode is preferably 2 to 20 cm ^2, 5 to 10 cm ² is more preferable. If the effective area of the electrode is less than 2 cm ² , it is difficult to obtain an electrolyzed water having a sufficient effective chlorine concentration with a small impressed voltage because the electrode is too small, and if it exceeds 20 cm ² , the whole apparatus becomes large.

A circuit for supplying electricity to the electrolytic electrodes 61 and 62 is composed of a power supply 101, an electrolytic switch 103, power control means 102, electrolytic electrodes 61 and 62, and electrolyzed water control means 104. In the case of the present embodiment shown in FIG. 1, the solenoid 72 is used as the electrolyzed water control means 104. The plus terminal of the power supply 101 is connected to the anode via the power control means 102, and the minus terminal of the power supply is connected to the cathode via the electrolytic switch 103. Power supply 101 is AC
It can be a power supply or a battery. Examples of the battery include a manganese dry battery, an alkaline dry battery, a nickel-cadmium dry battery, a nickel-hydrogen dry battery, and a lead battery.

The water to be electrolyzed is electrolyzed in the electrolysis section 6 and temporarily stored in the electrolyzed water storage section 8. The electrolytic water storage section 8 may be a hard container or a soft variable capacity container. The variable capacity container refers to a container whose capacity changes according to the liquid volume, including a flexible container, and includes, for example, containers made of an elastomer such as silicone rubber or butyl rubber, polyethylene, or vinyl chloride. In the case of a rigid container, a vent for allowing gas to flow outside the container is provided. It is preferable to use a disinfecting filter for preventing invasion of bacteria in the vent. It is preferable to use a hydrophobic porous membrane for the sterilization filter. The capacity of the electrolyzed water storage section 8 is preferably slightly larger than that of the electrolyzed water storage section 5.

The electrolyzed water reservoir 8 has an electrolyzed water inlet 83,
An electrolyzed water outlet 84 and an electrolyzed water sampling port 82 are provided. The electrolyzed water inlet 83 is provided so that the inflow speed of the electrolyzed water is not affected by the amount of liquid in the electrolyzed water storage 8.
Is preferably provided at the upper end. Further, the electrolyzed water outlet 84 is preferably provided at the lower end so that the electrolyzed water in the electrolyzed water reservoir 8 can flow out to the end.

Further, an electrolytic water storage amount monitor may be provided so that the electrolytic water storage unit 8 does not become full, and the electrolyzed water control means such as the solenoid 72 may be operated according to the monitor. As the electrolytic water storage amount monitor, a liquid level detector, a weight detector, a pressure detector and the like can be used.
When a flexible container having a variable capacity is used as the electrolyzed water storage unit, a weight detector such as a strain gauge for monitoring the amount of electrolyzed water in the electrolyzed water storage unit is provided. The electrolytic water storage unit 8 is controlled so as not to fall below a predetermined amount.
It is preferable to control the operation of the electrolyzed water control means according to the stored amount of electrolyzed water. In the present embodiment, since the head is of the head type, the solenoid 72 operates according to the amount of stored electrolyzed water in the electrolyzed water storage unit 8, and the tube 71 is opened and closed.

The electrolyzed water sampling port 82 is preferably provided below the electrolyzed water reservoir 8, and has a valve function such as a three-way valve or a rubber stopper. A collecting means such as a syringe can be connected to the electrolytic water collecting port 82 to collect the electrolytic water. By providing the electrolyzed water sampling port 82, in addition to the application to the normal oral cavity from the injection unit 3, it is possible to treat with an appropriate amount of electrolyzed water at any time. It is also used to improve usability. When the syringe connected to the electrolytic water sampling port 82 is used for oral care, it is preferable to use a syringe of 5 to 50 ml, more preferably 10 to 20 ml. For oral care
Since the amount used at one time is about 10 to 20 ml, if it is 5 ml or less, it must be collected twice or more. If it is 50 ml or more, it is too large and is not suitable for oral care.

The electrolyzed water stored in the electrolyzed water storage section 8 flows out of the electrolyzed water outlet 84 by the operation of the pump 93.
After passing through the tubes 91, 92, and 4, it reaches the injection unit 3 and is injected from the injection port 31. The tubes 91, 92, 4, and the electrolyzed water circulation section of the injection section 3 constitute a second water passage from the electrolyzed water storage section 8 to the injection nozzle 31. Pump 9
The electrolyzed water circulation part 3 constitutes a part of the second channel.

When disinfecting or disinfecting a narrow part such as in oral care, it is preferable to separate the main body for generating and storing the electrolyzed water from the injection unit applied to the affected part. Depending on the positional relationship of the main body, the energy for sending and injecting the electrolyzed water differs, and it becomes difficult to inject at a constant speed. In particular, when the height difference between the injection unit and the main body is 50 cm or more, and a simple and small pump is used, the change in the liquid sending speed may be large. But,
The present invention is a liquid sending means at the time of electrolysis where a change in flow velocity is a problem,
Since the liquid feeding means for jetting for disinfection is provided separately and independently, the pump 93 can be downsized, and the pump used for this can be a diaphragm pump, a centrifugal pump, or a piston pump. Is preferred. The electrolyzed water stored in the electrolyzed water storage unit 8 is adjusted to a substantially constant property by the operation of the electrolyzing unit 6 and the electrolyzed water control means. Effect does not decrease. Further, the electrolyzed water control means may be provided in the main body 2 or the injection unit 3. It is preferable that the injection section 3 is provided in the main body 2 because the weight of the injection section 3 can be reduced. By having the configuration of the present invention, it is possible to inject acidic water having a predetermined effective chlorine concentration even when the height difference between the injection unit and the main body is 50 cm or more. The preferred height difference is 50 cm or more and 1.5 m or less.

The tube 4 connecting the main body 2 and the injection section 3 is preferably an elastomer tube in order to improve the operability of the injection section 3, and is most preferably a fluororesin tube. The length of the tube 4 is preferably 50 to 200 cm, more preferably 50 to 100 cm. In the case of oral care, if it is 50 cm or less, the main body 2 and the patient's mouth are close to each other, and the operability of the injection unit 3 is reduced. On the other hand, when the distance is 200 cm or more, the liquid feeding path becomes longer, and the operability similarly decreases. The inner diameter of the tube 4 is preferably 1-4 mm,
mm is more preferable. If it is 1 mm or less, tube 4
The flow resistance in the inside increases, the load of the pump 93 increases, and when the diameter is 4 mm or more, the amount of electrolytic water filled in the tube 4 increases, and as a result, the weight of the tube 4 increases. When this occurs, the weight becomes heavy, leading to a decrease in operability.

The injection section 3 may have any shape as long as it can be easily gripped, and a pencil type is preferable, but it is needless to say that the injection section 3 is not limited to this shape. A nozzle for oral cavity cleaning, a periodontal pocket cleaning needle, or the like can be attached to the injection port 31 according to the application. Further, the ejection unit 3 is provided with a discharge switch 32. When the discharge switch 32 is pressed, the pump 93 is operated, and the electrolytic water is injected.

The discharge switch 32 includes electrolytic electrodes 61 and 62
An electrolytic switch for energizing the solenoid and opening the solenoid 72 may also be used. In this case, when the discharge switch 32 is pressed, the solenoid 72 is opened, and at the same time as the water to be electrolyzed flows in the electrolysis section 6, electrolysis is started to generate electrolyzed water. On the other hand, when the pump 93 operates in conjunction with the operation, the electrolytic water is injected from the injection nozzle 31. It goes without saying that the electrolytic switch may be provided separately from the discharge switch and may be operated independently of each other.

In the electrolysis section 6, when the water to be electrolyzed flows and electricity is supplied between the electrode pairs 61 and 62, the water to be electrolyzed is electrolyzed. Chlorous acid (HClO) is generated, sodium hydroxide (NaOH) and hydrogen gas (H2) are generated on the cathode side,
Electrolyzed water containing these is obtained.

The pH of the electrolyzed water injected from the injection nozzle 31 is preferably 3 to 7, more preferably 4 to 6.5, and even more preferably 4.5 to 5.5. . The figure shows the available chlorine contained in the electrolyzed water, namely, hypochlorous acid (HClO), hypochlorite ion (OC).
1 ⁻ ) and the change in the abundance ratio of chlorine molecules (Cl ₂ ) with respect to pH. As shown in the figure, when the pH is less than 3, the abundance ratio of chlorine molecules in the electrolytic water tends to increase, and the effective chlorine amount becomes unstable. Conversely, if the pH exceeds 7, the abundance ratio of hypochlorite ion in the electrolytic water tends to increase, and the disinfecting / bactericidal effect decreases. Therefore, the pH of the electrolyzed water is preferably in the above range.

The flow rate of the electrolytic water injected from the injection nozzle 31 may be changed according to the intended use by using a shift switch of the pump 93 (not shown). For example, in the case of mouth washing, 0.1 to 10 ml / s
ec, and more preferably 0.2 to 8 ml / sec. Electrolyzed water injected from the nozzle is
The effective chlorine concentration is preferably from 10 to 100 ppm, more preferably from 20 to 80 ppm. When the effective chlorine concentration is less than 10 ppm, when used for sterilization and disinfection in the human body, the protein is inhibited and sufficient disinfection and disinfection effects cannot be obtained. On the other hand, if it exceeds 100 ppm, there are problems such as safety for human body and chlorine odor.

The electrolytic water of the injection nozzle 31 is, for example,
One or more spray forms, such as a form that sprays one or more lines of electrolyzed water, a form that sprays like a shower, a form that sprays as a mist, and a form that sprays a jet in a pulsating or rotating manner Or a combination of these multiple injection modes.

In the electrolyzed water generator 1 as described above, the load pressure on the pump is changed by moving up and down the portion (tube 4) from the main body 2 of the second water passage, and the flow rate is changed accordingly. Electrolyzed water with a constant effective chlorine concentration can always be supplied.
