The electrolysis unit provided in the electrolysis apparatus as described above generates hydrogen at the cathode and oxygen gas at the anode by electrolyzing tap water. At the anode, chloride ions contained in water react to generate chlorine. This chlorine reacts with water to produce hypochlorous acid.

Thus, in order to generate hypochlorous acid having a certain concentration or more by the electrolysis unit, it is necessary to supply tap water containing a predetermined chloride ion to the electrolysis unit. That is, when pure water is injected into the water supply tank or when water that does not contain chloride ions such as well water and does not contain chloride ions is injected, the concentration of water that is effective for the electrolyzed water produced by the electrolyzer is low. There is a problem that hypochlorous acid cannot be produced and a sufficient effect cannot be exhibited.

It becomes possible.

At this time, it is possible to measure the contact time between the injected water and the sustained-release material by measuring the time due to the fall of the contents, and it is possible to ensure the contact time. Thereby, it is possible to secure the amount of release from the sustained release material to the stored water, and it is possible to generate water having a predetermined chloride ion concentration.

Hereinafter, an embodiment of a water supply tank for an electrolyzer according to the present invention will be described with reference to the drawings. First, an air cleaning apparatus that performs air cleaning using water supplied from a water supply tank as an electrolysis apparatus will be described as an example. FIG. 1 is a rear perspective view of an air cleaning device (electrolysis device) 10 according to the present embodiment, FIG. 2 is a front perspective view of the water tank 1 of FIG. 1 being pulled out, and FIG. 3 is a rear exploded view of the air cleaning device of FIG. Each perspective view is shown.

The air cleaning apparatus 10 as an electrolysis apparatus in the present embodiment is formed with an air suction port 12 on a side surface of a rectangular main body 11 and a clean air outlet 13 on an upper surface. The ventilation path which connects the air suction inlet 12 and the blower outlet 13 is formed. In this ventilation path, a blower as a blowing means (not shown) and a gas-liquid contact member 17 provided in a water tank 16 described later are disposed. As a result, when the blower is operated, the outside air that has entered the ventilation path passes through the gas-liquid contact member 17 and is then discharged to the outside from the air outlet 13.

And the lower part of the main body 11 serves as a water tank storage part 14, and an insertion / removal port 15 opened rearward is formed on the lower rear surface of the main body 11 corresponding to the water tank storage part 14. In this insertion / removal port 15, a water tank 16 having an upper opening is accommodated in a slide-type manner so as to be slidable back and forth with respect to the main body 11 by a handle 16 A at the lower rear surface.

The rear part of the water tank 16 is a bulging part 16B that protrudes rearward from the main body 11 in a state where the water tank 16 is mounted on the main body 11 of the air cleaning device 10. A partition 19 that closes the insertion / removal port 15 of the main body 11 is erected in the water tank 16, and a filter chamber 16 F is formed on the main body 11 side by the partition 19. ) Is formed with a tank chamber 16T.

In the filter chamber 16F of the water tank 16, a gas-liquid contact member 17 having high water retention as a gas-liquid contact means is erected in a state where the lower part is immersed in the water stored in the water tank. In this embodiment, the gas-liquid contact member 17 is a filter member adopting a honeycomb structure, and has a structure in which a gas-liquid contact area is wide and is not easily clogged. The gas-liquid contact member 17 is made of a material that is less reactive with the electrolyzed water generated in the water tank 16, that is, a material that is less deteriorated by the electrolyzed water, such as a polyolefin resin, a PET resin, or a vinyl chloride resin. A material such as a resin, a fluororesin, or a ceramic resin is used.

In the tank chamber 16T of the water tank 16, a water supply tank 1 according to the present invention, which will be described in detail later, is stored. A recess 20 is formed in the bottom surface of the tank chamber 16T, and a protrusion 18 is provided in the recess 20 to push up and open a water stop valve 31 (to be described later) of the water supply tank 1.

Therefore, by storing the water supply tank 1 in the tank chamber 16T, a lid member 6 to be described later, which is the lowermost part, is stored in the recess 20 by the weight of the water supply tank 1. In this state, the water stop valve 31 provided on the lid member 6 of the water supply tank 1 is pushed up and opened by the protrusion 18, and the water in the water supply tank 1 is supplied into the water tank 16. Since the recess 20 in the water tank 16 is configured to communicate with the filter chamber 16F, a predetermined water level is maintained in the recess 20 and the filter chamber 16F.

In the main body 11, an electrode unit 21 is provided in which at least a part is immersed in the water in the water tank 16 (filter chamber 16 F) by inserting the water tank 16 into the main body 11.

As shown in the schematic configuration diagram of FIG. 4, the electrode unit 21 includes at least a pair of

electrodes

21A and 21B. When the

electrodes

21A and 21B are energized, the water stored in the water tank 16 is electrically Decomposed (electrochemical treatment) to generate active oxygen species. Here, the reactive oxygen species are oxygen molecules having an oxidation activity higher than that of normal oxygen and related substances, and are so-called narrowly defined as superoxide anion, singlet oxygen, hydroxyl radical, or hydrogen peroxide. These active oxygens include so-called broadly active oxygens such as ozone and hypohalous acid. The water tank 16 is arranged in the vicinity of the gas-liquid contact member 17 and is configured to be able to quickly supply the active oxygen species generated by electrolyzing the water supplied from the water supply tank 1 to the gas-liquid contact member 17.

The

electrodes

21A and 21B are, for example, electrode plates in which the base is Ti (titanium) and the coating layer is made of Ir (iridium) or Pt (platinum). For example, when electricity is supplied to tap water by the electrode, in the electrode constituting the cathode,
2H2O + 2e- → H2 + 2OH-
In the electrode constituting the anode,
2H2O → 4H ++ O2 + 4e-
At the same time, the chloride ion contained in the water
2Cl- → Cl2 + 2e-
In addition, this Cl2 reacts with water,
Cl2 + H2O → HClO + H ++ Cl−
It becomes.

In this configuration, when the electrode is energized, HClO (hypochlorous acid) having high sterilizing power is generated, and the electrolyzed water supplied with the hypochlorous acid is sucked up by the capillary phenomenon of the gas-liquid contact member 17. Then, the outside air sucked into the main body 11 from the air suction port 12 is passed through the gas-liquid contact member 17. Thereby, it is possible to prevent germs from growing on the gas-liquid contact member 17 and to inactivate viruses floating in the outside air passing through the gas-liquid contact member 17. Further, when the odor also passes through the gas-liquid contact member 17, it reacts with hypochlorous acid in the electrolytic water, and is ionized and dissolved to be removed from the air and deodorized.

Next, the water supply tank 1 according to the present invention will be described in detail with reference to FIGS. 5 is a perspective view of the water supply tank 1 (installed state of the air purifier 10), FIG. 6 is a front view of the water supply tank 1 of FIG. 5, FIG. 7 is a front view of the water supply tank 1 (water injection state), and FIG. FIG. 9 is a perspective view of the water amount adjusting member 7 (upper perspective view in the water pouring state), and FIG. 9 is a perspective view of the water amount adjusting member 7 (lower perspective view in the water pouring state).

The water supply tank 1 is a synthetic resin tank through which internal water can be seen from the outside, and a water supply port 2 is formed at a lowermost position in the state of being provided in the tank chamber 16T of the air purifier 10. Yes. The water supply port 2 is formed by a so-called wide-mouthed opening having a predetermined diameter, and the opening edge is configured to have a side surface 2 A in which the outer edge rises outward and the outer surface is threaded. A lid member 6 for closing the water supply port 2 is detachably provided by threading formed on the side surface 2A.

The lid member 6 is formed with a communication portion 32 that communicates the inside and outside of the water supply tank 1, and a water stop valve 31 is disposed on the water supply tank 1 side of the communication portion 32. The water stop valve 31 has a shaft 33 that is located in the communication portion 32 and extends toward the outside of the water supply tank 1. The shaft 33 is always biased in a direction in which the water stop valve 31 closes the communication portion 32 by a biasing means (not shown). In the state where the water supply tank 1 is provided in the tank chamber 16T of the air purifier 10 as described above so that the water supply port 2 (the cover member 6) is at the lowest position, the shaft 33 of the cover member 6 is The protrusion 18 provided in the air cleaning device 10 is pushed up against the urging force of the urging means, and thereby the communication portion 32 is opened.

In this embodiment, the water supply port 2 is provided with a water injection amount adjusting member (pressure loss cap) 7 for adjusting the water injection amount per unit time from the water supply port 2. In the present embodiment, the water injection amount adjusting member 7 may be detachable from the water supply port 2, but is not limited thereto.

As shown in the perspective views of FIGS. 8 and 9, the water injection amount adjusting member 7 protrudes toward the water supply tank 1 and has a storage portion 8 having a predetermined volume. The surface inside the water supply tank 1 of the storage unit 8 (that is, the bottom surface of the storage unit 8 in a state where the water supply port 2 is placed at the upper side when water is injected into the water supply tank 1) A plurality of communication holes 9 having a predetermined dimension are formed. It is assumed that the volume of the reservoir 8 and the number and size of the communication holes 9 formed in the surface 8A are set in advance by the amount of water injected into the water supply tank 1 per unit time.

And the latching | locking part 8B formed by folding outward is formed in the outer edge by the side of the opening of this storage part 8. As shown in FIG. Thereby, the said water injection amount adjustment member 7 is latched by the opening edge part of the water supply port 2 so that attachment or detachment is possible.

On the other hand, a handle portion 35 is provided at the uppermost portion in a state where the water supply tank 1 is provided in the air cleaning device 10. In the present embodiment, the handle portion 35 is formed integrally with the water supply tank 1. In addition, at the time of pouring water into the water supply tank 1, the water supply port 2 is the uppermost part, and in this state, the lowermost part, in this case, the handle part 35, is the flattest surface 35A. ing. Thereby, the stable support by the flat surface 35A is attained at the time of water injection.

Further, a sustained release material opening 36 is formed on the side of the water supply tank 1 where the handle portion 35 is provided, and the sustained release material opening 36 can be freely opened and closed by a sustained release material mounting member 41. It is blocked.

The sustained-release material mounting member 41 stands up outward from the opening edge of the sustained-release material opening 36 and is detachably provided on a side surface having a threaded outer surface. The sustained release material mounting member 41 includes a sustained release material accommodation portion 42 that protrudes outward (opposite to the water supply port 2). A material 40 is accommodated.

A plurality of communication holes 43 that allow passage of water and prohibit passage of the sustained release material 40 are formed on the surface of the sustained release material accommodation portion 42 on the side of the water supply port 2.

The sustained release material 40 accommodated in the sustained release material accommodation portion 42 releases chloride ions in an amount proportional to the contact time with water. In this embodiment, a structural material having porosity and hydrophilicity in a state where a water-soluble substance containing chloride ions such as sodium chloride and potassium chloride is kneaded with a hydrophobic substance, for example, a water-insoluble resin such as a saturated fatty acid. It is comprised by embedding in. Thereby, while the sustained release material 40 is in contact with water, water enters through a gap (path) generated between the structural material and the hydrophobic material, and from the water-soluble substance containing chloride ions, An amount of chloride ions proportional to the contact time is released into the water in contact (in this case, water in the water supply tank 1).

FIG. 10 shows the elution amount of chloride ions with respect to the contact time of the sustained release material 40 employed in this embodiment with water. In this case, the amount of chloride ions with respect to the contact time when 1 g of the sustained release material is brought into contact with 100 mL of pure water is shown. According to this, about 6.2 mg of chloride ions are eluted at a contact time of 5 minutes, and about 10.6 mg of chloride ions are eluted at a contact time of 10 minutes. From this, it can be said that the sustained-release material 40 elutes water with an amount of chloride ions proportional to the contact time with water.

With the above configuration, water supply operation to the water supply tank 1 and water supply operation from the water supply tank 1 to the air cleaning device 10 will be described. When the water in the water supply tank 1 runs out, the air cleaning device 10 notifies the user that the water in the water supply tank 1 has run out by detecting a low water level by means of a built-in water level detection means. The user holds the handle portion 35 and removes the water supply tank 1 from the tank chamber 16T of the air cleaning device 10. And it has so that the water supply port 2 may become an upper part and the sustained release material 40 (grip part 35 side) may become a lower part, and the cover member 6 which obstruct | occludes the water supply port 2 is open | released.

And tap water is supplied from the open water supply port 2. The water poured into the water supply tank 1 from the water supply port 2 is sequentially filled from the lower part of the water supply tank 1 by its own weight. Here, since the sustained release material 40 is provided in the lower part of the water supply tank 1, that is, in this embodiment, at the lowermost position in this state, while the state (posture) is maintained, it is actually While the water injection operation is being performed, the injected water and the sustained release material 40 are in contact with each other, and during the contact, an amount of chloride ions proportional to the contact time is obtained from the sustained release material 40. Is released.

In the present embodiment, a water injection amount adjusting member 7 is provided at the water supply port 2 for injecting water into the water supply tank 1. Therefore, regardless of the flow rate of water supplied from a water pipe or the like, the water injection rate adjusting member 7 limits the water injection rate (water injection amount per unit time) into the water supply tank 1.

Therefore, the time until the water supply tank 1 becomes full can be kept constant by the water injection amount adjusting member 7, thereby ensuring a certain contact time between the sustained release material 40 and the water in the water supply tank 1. It becomes possible to do.

Thereby, the amount of chloride ions released from the sustained release material 40 proportional to the contact time with the water in the water supply tank 1 is released to the water injected according to the amount of water injected through the water supply port 2. Can do. Therefore, water having a predetermined chloride ion concentration can be supplied from the water supply tank 1 to the air cleaning device (electrolysis device) 10.

FIG. 11 shows the chloride ion concentration with respect to the contact time when the above-mentioned sustained release material is 20 g and the amount of water injected into the water supply tank 1 is 4 L of pure water. According to this, when the contact time (water injection time) between the sustained release material and the water in the water supply tank 1 is about 5 minutes and 10 seconds, the water that was pure water has a chloride ion concentration of about 31 mg / L. When the contact time (water injection time) was about 10 minutes, the pure water had a chloride ion concentration of about 48 mg / L.

Therefore, a plurality of types of water injection amount adjusting members 7 different for each water injection amount per unit time into the water supply tank 1 may be configured for the water supply tank 1. In this case, the type of water supplied to the water supply tank 1, that is, water having different chloride ion concentrations, or chloride ions adjusted in the water supply tank 1 even if the water has the same chloride ion concentration The water injection amount adjusting member 7 is attached to the water supply port 2 according to the concentration. Thereby, it is possible to pour water into the water supply tank 1 at an appropriate speed according to the type of water to be used and the mode of use, and appropriately secure and adjust the contact time between the sustained release material 40 and the poured water. It becomes possible to do. Therefore, water with an appropriate chloride ion concentration can be supplied from the water supply tank 1 to the electrolysis device, in this embodiment, the air cleaning device 10.

For this reason, the water supply tank 1 employed in this embodiment is filled with water at 4L, and when pure water is injected, the water injection time until the water is filled is about 5 minutes and 10 seconds by the water injection amount adjusting member 7. If what is set to become is, chloride ions can be released from the sustained-release material so that the chloride ion concentration is about 31 mg / L. If the water injection amount adjusting member 7 to be used is set so that the water injection time to full water is about 10 minutes, chloride ions from the sustained release material are adjusted so that the chloride ion concentration is about 48 mg / L. Can be released.

And when it reaches a predetermined full water level (for example, when the water level flush with the end of the water supply port 2 is the full water level, or when the water level is displayed in advance in the water supply tank 1 itself), The user closes the water supply port 2 with the lid member 6, inverts the water supply port 2 to a position where the water supply port 2 is at the bottom and the sustained release material 40 is at the top, and installs the water supply port 2 in the tank chamber 16T of the air cleaning device 10.

Thereby, the water stop valve 31 provided in the lid member 6 of the water supply tank 1 is pushed up by the protrusion 18 provided on the air cleaning device 10 side, the communication portion 32 is opened, and the water tank 16 is filled with water. Thus, water supply from the water supply tank 1 to the water tank 16 is stopped.

When the water supply tank 1 is provided in the air cleaning device 10 in a full water state, the sustained release material 40 is positioned above the water surface in the water supply tank 1 so that the sustained release material 40 and the water in the water supply tank 1 are in contact with each other. It is assumed that there is no state. In this case, the full water state means that water is poured into the water supply tank 1 to a water level that is substantially flush with the end of the water supply port 2, and in this state, the water tank 16 of the air cleaning device 10 is full. In addition, it is assumed that the water level in the water supply tank 1 is positioned below the lower surface of the sustained release material 40 in a state where the air purifier 10 is installed.

In addition, even if it is a case where the water in the water tank 16 is at a low water level, even when the water is poured into the water supply tank 1 up to a water level that is substantially flush with the end of the water supply port 2, Since a certain amount of water is supplied into the water tank 16 from the water supply tank 1 in the state where it is installed in the air cleaning device 10, the water level in the water supply tank 1 is lower than the lower surface of the sustained release material 40 provided at the top in this state. It will be located below. In addition to this, as described above, if the full water level to the water supply tank 1 is displayed in advance and water injection is performed only up to the water level, the water supply tank 1 is reversed, and the sustained release material By positioning 40 at the top, contact between the sustained release material 40 and the water in the water supply tank 1 can be prohibited.

Thus, according to the present embodiment, the sustained-release material 40 provided in the water supply tank 1 is in contact with the water at least while the water is being injected into the interior from the water supply port 2, and the air cleaning device 10 is in contact with the water. Since it is arranged at a position where it does not come into contact with the injected water in the provided state, the water and the sustained release material 40 come into contact with each other while the water is being injected into the interior from the water supply port 2, and An amount of chloride ions proportional to the contact time can be released from the release material 40 into the water inside the tank. And after completion | finish of the water injection to the inside, in the state provided in the air purifying apparatus 10 so that the water supply port 2 may become the lowest part, the sustained release material 40 becomes non-contact with the water inside the tank 1 stored. Therefore, in this state, it can be avoided that chloride ions are released from the sustained release material 40 into the water stored therein.

As a result, the sustained release material 40 can be brought into contact with the water to be injected for the time required for injecting water into the interior from the water supply port 2, and an amount of chloride ions proportional to the contact time can be released into the water. . Therefore, the water containing the required amount of chloride ions in the air cleaning device 10 can be supplied from the water supply tank 1 to the air cleaning device 10 without using any special measuring means such as a concentration detecting means. Electrolyzed water can be appropriately generated by the electrolysis treatment by the electrolysis unit 21.

In particular, the sustained release material 40 is provided at the upper position with the water supply port 2 in the lowest position, and when it is provided in the air cleaning device 10 in the full water condition, by being positioned above the water surface, In the state provided in the air cleaning device 10, the water in the water supply tank 1 can be reliably brought into a non-contact state with the sustained release material 40. Thereby, the inconvenience that chloride ions are released from the sustained release material 40 to the water in the water supply tank 1 more than necessary, for example, chloride ions are excessively released into the water supply tank 1, or the sustained release material 40. It is possible to avoid the inconvenience that the life of the battery becomes shorter.

In this embodiment, as shown in FIG. 6, the sustained-release material opening 36 is formed with a protrusion 36 A that protrudes outward from the end opposite to the water supply port 2 of the tank portion of the water supply tank 1. And the end of the sustained release material 40 is provided at the outer end of the protrusion 36A.

Thus, a space 37 having a predetermined dimension in the vertical direction and opening downward is formed by the projection 36A at a position corresponding to the lower side of the sustained release material 40 in a state provided in the air cleaning device 10. As a result, in the state provided in the air cleaning device 10, the stored water and the sustained release material 40 are separated from each other via the space 37, so that the water supply tank 1 is more reliably provided. It is possible to avoid contact between the water inside and the sustained release material 40, and release of a predetermined amount or more of chloride ions can be suppressed.

Thus, regardless of the type of water supplied to the water supply tank 1, that is, the chloride ion concentration, the air cleaning device 10 is supplied with water having a chloride ion concentration suitable for producing electrolyzed water. 1, the electrolysis unit 21 provided in the air cleaning device 10 generates electrolyzed water containing active oxygen species by electrochemical treatment using the water, and this electrolyzed water. It becomes possible to purify the air using the. Therefore, air can be purified by electrolyzed water containing hypochlorous acid at a predetermined concentration.

In particular, even when pure water or other tap water having a low chloride ion concentration is poured into the water supply tank 1, the electrolyzed water containing hypochlorous acid having a concentration capable of effectively purifying air is used. It is possible to realize processing with a high purification effect.

In the present embodiment, the amount of water injected per unit time to be injected into the water supply tank 1 is adjusted by the water injection amount adjusting member 7, but the contact between the sustained release material 40 and the water in the water supply tank 1 at the time of water injection. The means for securing the predetermined time is not limited to this.

For example, the side of the water supply tank 1 may be provided with timing means capable of timing when the contents, for example, a plurality of types of liquids having different specific gravity by falling, fall. Thereby, in the state provided in the air purifying apparatus 10, the water supply port 2 provided in the position which becomes the lowermost part is turned into the uppermost part when the water is injected into the inside, and the time measuring means is reversed together with this. By doing so, it is possible to measure the time by dropping the contents.

Therefore, it is possible to measure the contact time between the water being poured and the sustained-release material 40 by measuring time due to the fall of the contents of the time measuring means, and it is possible to secure such contact time. Thereby, the discharge | release amount to the water stored from the sustained release material 40 can be ensured, and it becomes possible to produce | generate the water of predetermined | prescribed chloride ion concentration.

In addition, the sustained release material in the present embodiment is provided in the water supply tank 1 so as to be exchangeable from the outside by the sustained release material mounting member 41 as described above. Therefore, when chloride ions are completely released from the sustained release material 40, it can be easily exchanged from the outside. This allows for permanent use.

At this time, the sustained-release material 40 to be used may contain a dye corresponding to the concentration of chloride ions to be supported. In this case, the sustained-release material mounting member 41 is configured such that at least the sustained-release material accommodating portion 42 can be seen through from the outside. As a result, the amount of chloride ions contained in the sustained release material 40 can be visually recognized using the amount of the pigment contained in the same manner as an index. Thereby, the replacement | exchange time of the sustained release material 40 can be recognized visually from the outside, and it can replace | exchange appropriately.

In the present embodiment, the air cleaning device 10 is described as an example of an electrolysis device, but the present invention is not limited to this, and at least a hypoxia is obtained by electrochemically treating (electrolyzing) water. The same effect can be obtained even in an apparatus that generates electrolyzed water containing active oxygen species such as chloric acid and sterilizes with the electrolyzed water, for example, a humidifier that sterilizes a water path such as a water tank. Can be played.
