Description
本発明は、空気中に水素を供給可能な加湿器に関する。 The present invention relates to a humidifier that can supply hydrogen to the air.
本発明者らにより発表された論文である下記の非特許文献１及び非特許文献２には、水に水素を溶存させた水素水に触れることで、皮膚の弾力性が向上したり、毛髪の滑らかさや毛髪の艶が増したり、深部体温を上昇させたりすることが開示されている。 The following non-patent literature 1 and non-patent literature 2, which are papers published by the present inventors, disclose that exposure to hydrogen water, which is water with hydrogen dissolved in it, improves skin elasticity, makes hair smoother and shinier, and raises core body temperature.
また、下記の特許文献１には、水素水のような還元水が皮膚の老化防止等に寄与することから、入浴剤に水素発生剤を用いた技術が開示されている。 In addition, the following Patent Document 1 discloses a technology that uses a hydrogen generating agent in bath additives, because reduced water such as hydrogen water contributes to preventing skin aging, etc.
また、下記の特許文献２には、水素水のような還元水を飲むと、胃腸症状の改善や活性酸素の除去といったアンチエイジング効果が期待されることから、水を電気分解して電解水を生成する技術が開示されている。 In addition, the following Patent Document 2 discloses a technology for producing electrolyzed water by electrolyzing water, based on the expectation that drinking reduced water such as hydrogen water will have anti-aging effects such as improving gastrointestinal symptoms and removing active oxygen.
さらに、下記の特許文献３には、水を電気分解して機能水を生成し、精製された機能水を霧化して大気中に放出する加湿器が開示されている。 Furthermore, the following Patent Document 3 discloses a humidifier that electrolyzes water to produce functional water, atomizes the purified functional water, and releases it into the atmosphere.
また、下記の特許文献４には、ミストを分子状水素が残存した状態で対象物に噴霧することができるミスト生成装置およびミスト生成方法が開示されている。 In addition, the following Patent Document 4 discloses a mist generating device and a mist generating method that can spray mist onto an object while still retaining molecular hydrogen.
一方、食塩水の電気分解で生じた次亜塩素酸を空気中へ放出して室内における殺菌及び消臭の効果を期待する製品も種々提供されている。 On the other hand, there are various products available that release hypochlorous acid produced by electrolysis of salt water into the air, with the hope of killing bacteria and deodorizing indoors.
上記の非特許文献１及び非特許文献２並びに特許文献１及び特許文献２で開示されているように、水素水が人体へ及ぼす好影響を考慮すると、水素水を霧化することで空気中に放出された水素を吸入することによっても人体への好影響が期待できる。 As disclosed in the above Non-Patent Documents 1 and 2 and Patent Documents 1 and 2, considering the positive effects of hydrogen water on the human body, it is expected that inhaling hydrogen released into the air by atomizing hydrogen water will also have a positive effect on the human body.
そこで、本開示の水素供給加湿器は、食塩水を電気分解して得た水素水の霧化によって空気中に水素を放出するのみならず、電気分解により生ずる副産物である次亜塩素酸も有効に活用することを課題とする。 Therefore, the hydrogen supply humidifier disclosed herein aims not only to release hydrogen into the air by atomizing hydrogen water obtained by electrolyzing saline solution, but also to effectively utilize hypochlorous acid, a by-product of the electrolysis.
本開示の水素供給加湿器は、食塩水を貯留する給水タンクと、前記食塩水を無隔膜電解により電気分解して、水素及び次亜塩素酸を含有する電気分解水とする電気分解部と、前記電気分解水から次亜塩素酸を除去して水素含有水とする濾過部と、前記電気分解水及び前記水素含有水を霧化する霧化部と、前記電気分解部の下流において、前記霧化部へ前記電気分解水が直接流れる第１流路と、前記濾過部へ前記電気分解水が流れる第２流路とに流路を切り替える流路切替部と、前記濾過部から前記霧化部へと前記水素含有水が流れる第３流路と、を備える。 The hydrogen supply humidifier of the present disclosure includes a water supply tank for storing saline solution, an electrolysis section for electrolyzing the saline solution by membraneless electrolysis to produce electrolyzed water containing hydrogen and hypochlorous acid, a filtration section for removing hypochlorous acid from the electrolyzed water to produce hydrogen-containing water, an atomization section for atomizing the electrolyzed water and the hydrogen-containing water, a flow path switching section downstream of the electrolysis section for switching the flow path between a first flow path through which the electrolyzed water flows directly to the atomization section and a second flow path through which the electrolyzed water flows to the filtration section, and a third flow path through which the hydrogen-containing water flows from the filtration section to the atomization section.
給水タンクに貯留される食塩水は、電気分解部において無隔膜電解により電気分解される。電気分解された食塩水は、水素及び次亜塩素酸を含有する電気分解水となる。この電気分解水の流れは第１流路と第２流路とに分岐し、どちらの流路を流れるかは流路切替部によって切り替えられる。 The salt water stored in the water supply tank is electrolyzed by diaphragmless electrolysis in the electrolysis section. The electrolyzed salt water becomes electrolyzed water containing hydrogen and hypochlorous acid. The flow of this electrolyzed water branches into a first flow path and a second flow path, and which path it flows through is switched by a flow path switching section.
第１流路は直接、霧化部へと連絡している。第１流路を流れる電気分解水は、霧化部により霧化され、水素及び次亜塩素酸を含有するミストが空気中に放出される。 The first flow path is directly connected to the atomization section. The electrolyzed water flowing through the first flow path is atomized by the atomization section, and a mist containing hydrogen and hypochlorous acid is released into the air.
一方、第２流路は、濾過部に連絡し、そこから第３流路を介して霧化部へと連絡している。第２流路を流れる電気分解水は、濾過部により次亜塩素酸が除去され、電気分解産物としては水素のみを含有する水素含有水となる。水素含有水は第３流路を流れて霧化部にいたり、そこで霧化され、水素のみを含有するミストが空気中に放出される。 Meanwhile, the second flow path is connected to the filtration section, and from there to the atomization section via the third flow path. The electrolyzed water flowing through the second flow path has hypochlorous acid removed by the filtration section, and the electrolysis product becomes hydrogen-containing water that contains only hydrogen. The hydrogen-containing water flows through the third flow path to the atomization section, where it is atomized, and a mist containing only hydrogen is released into the air.
すなわち、水素及び次亜塩素酸を含有するミストが空気中に放出されるか、又は、水素のみを含有するミストが空気中に放出されるかを、流路切替部により選択することが可能となる。たとえば、無人環境下においては、電気分解水の流れを第１流路に切り替えることで、水素とともに放出される次亜塩素酸によって、室内の殺菌及び消臭を図ることができる。一方、有人環境下においては、電気分解水の流れを第２流路に切り替えることで、次亜塩素酸が除去されることで、水素のみを含有し塩素臭のないミストが放出されることとなる。 In other words, the flow path switching unit can select whether a mist containing hydrogen and hypochlorous acid is released into the air, or a mist containing only hydrogen is released into the air. For example, in an unmanned environment, the flow of electrolyzed water can be switched to the first flow path, and the hypochlorous acid released together with hydrogen can sterilize and deodorize the room. On the other hand, in a manned environment, the flow of electrolyzed water can be switched to the second flow path, and the hypochlorous acid can be removed, resulting in the release of a mist containing only hydrogen and without the chlorine odor.
なお、前記電気分解部は前記給水タンク内に設けられていることとしてもよい。 The electrolysis unit may be provided inside the water supply tank.
また、前記給水タンク中の食塩水はｐＨ５～７．５に調整されていることが望ましい。 It is also desirable that the saline solution in the water tank be adjusted to a pH of 5 to 7.5.
本開示の水素供給加湿器によれば、食塩水を電気分解して得た水素水の霧化によって空気中に水素を放出するのみならず、電気分解により生ずる副産物である次亜塩素酸も有効に活用することが可能となる。 The hydrogen supply humidifier disclosed herein not only releases hydrogen into the air by atomizing hydrogen water obtained by electrolyzing salt water, but also makes it possible to effectively utilize hypochlorous acid, a by-product of electrolysis.
以下、図面を参照しつつ本開示の水素供給加湿器の実施形態を説明する。なお、以下の説明で言及する各図面は模式図であって、図中に示すサイズ及び形状は実際のサイズ及び形状を必ずしも反映していない。また、各図において共通して用いられている符号は、特段の説明がない限り同一の構成を指し示すものである。 Below, an embodiment of the hydrogen supply humidifier of the present disclosure will be described with reference to the drawings. Note that the drawings referred to in the following description are schematic diagrams, and the sizes and shapes shown in the drawings do not necessarily reflect the actual sizes and shapes. Furthermore, symbols commonly used in each drawing indicate the same configuration unless otherwise specified.
（１）第１の実施形態
図１は、第１の実施形態の水素供給加湿器１０の概要を示す模式図である。本実施形態の水素供給加湿器１０は、食塩水１００（図２及び図４参照）を貯留する給水タンク２０と、前記食塩水１００を無隔膜電解により電気分解して、水素及び次亜塩素酸を含有する電気分解水１１０（図２及び図４参照）とする電気分解部３０と、前記電気分解水１１０から次亜塩素酸を除去して水素含有水１２０（図２参照）とする濾過部５０と、前記電気分解水１１０及び前記水素含有水１２０を霧化する霧化部６０と、前記電気分解部３０の下流において、前記霧化部６０へ前記電気分解水１１０が直接流れる第１流路４１と、前記濾過部５０へ前記電気分解水１１０が流れる第２流路４２とに流路を切り替える流路切替部４０と、前記濾過部５０から前記霧化部６０へと前記水素含有水１２０が流れる第３流路４３と、を備える。第３流路４３は、霧化部６０の手前で合流部４４を介して第１流路４１と合流する。霧化部６０としては、蒸気式、気化式、バブリング式、超音波式又はハイブリッド式等、加湿器として公知の機構を採用することができる。また、水素供給加湿器１０は、空気清浄機の一部として構成されていてもよい。
(1) First Embodiment FIG. 1 is a schematic diagram showing an overview of a hydrogen supply humidifier 10 according to a first embodiment. The hydrogen supply humidifier 10 of this embodiment includes a water supply tank 20 that stores saline solution 100 (see Figures 2 and 4), an electrolysis unit 30 that electrolyzes the saline solution 100 by diaphragm-less electrolysis to produce electrolyzed water 110 (see Figures 2 and 4) containing hydrogen and hypochlorous acid, a filtration unit 50 that removes hypochlorous acid from the electrolyzed water 110 to produce hydrogen-containing water 120 (see Figure 2), an atomization unit 60 that atomizes the electrolyzed water 110 and the hydrogen-containing water 120, a flow path switching unit 40 downstream of the electrolysis unit 30 that switches the flow path between a first flow path 41 through which the electrolyzed water 110 flows directly to the atomization unit 60 and a second flow path 42 through which the electrolyzed water 110 flows to the filtration unit 50, and a third flow path 43 through which the hydrogen-containing water 120 flows from the filtration unit 50 to the atomization unit 60. The third flow path 43 merges with the first flow path 41 via a junction 44 just before the atomization unit 60. As the atomization unit 60, a mechanism known as a humidifier, such as a steam type, an evaporation type, a bubbling type, an ultrasonic type, or a hybrid type, can be adopted. Furthermore, the hydrogen supply humidifier 10 may be configured as a part of an air purifier.
すなわち、本実施形態の水素供給加湿器１０では、食塩水１００は給水タンク２０から電気分解部３０に至り、電気分解に供され、電気分解水１１０となる。食塩水１００の塩化ナトリウム濃度は、０．１～１０質量％が望ましい。電気分解部３０から霧化部６０までの電気分解水１１０の流れは、流路切替部４０で第１流路４１と第２流路４２とに分岐する。第１流路４１と第２流路４２との分岐部には流路切替部４０が設けられている。この流路切替部４０の手動制御又は自動制御により、電気分解水１１０の流れは第１流路４１及び第２流路４２のいずれかに切り替えられる。第１流路４１は霧化部６０と直接連絡している。一方、第２流路４２は、濾過部５０、第３流路４３及び合流部４４を介して霧化部６０と連絡している。濾過部５０には、活性炭又は亜硫酸カルシウム等の、塩素及び次亜塩素酸は吸着・分解するが水素は吸着・分解しない吸着剤が充填されている。 That is, in the hydrogen supply humidifier 10 of this embodiment, the saline solution 100 reaches the electrolysis unit 30 from the water supply tank 20, where it is subjected to electrolysis and becomes electrolysis water 110. The sodium chloride concentration of the saline solution 100 is preferably 0.1 to 10 mass%. The flow of the electrolysis water 110 from the electrolysis unit 30 to the atomization unit 60 branches into a first flow path 41 and a second flow path 42 at the flow path switching unit 40. The flow path switching unit 40 is provided at the branching point of the first flow path 41 and the second flow path 42. By manual or automatic control of this flow path switching unit 40, the flow of the electrolysis water 110 is switched to either the first flow path 41 or the second flow path 42. The first flow path 41 is directly connected to the atomization unit 60. On the other hand, the second flow path 42 is connected to the atomization unit 60 via the filtration unit 50, the third flow path 43, and the junction unit 44. The filtration section 50 is filled with an adsorbent, such as activated carbon or calcium sulfite, that adsorbs and decomposes chlorine and hypochlorous acid but does not adsorb or decompose hydrogen.
図２は、本実施形態の水素供給加湿器１０において、電気分解水１１０の流れが流路切替部４０で第１流路４１に切り替えられている状態を示す。給水タンク２０に貯留されている食塩水１００は、電気分解部３０に至ると下記反応式にて電気分解に供されて水素及び次亜塩素酸ナトリウムを含有する電気分解水１１０となる。 Figure 2 shows the state in which the flow of electrolyzed water 110 is switched to the first flow path 41 by the flow path switching unit 40 in the hydrogen supply humidifier 10 of this embodiment. When the salt water 100 stored in the water supply tank 20 reaches the electrolysis unit 30, it is subjected to electrolysis according to the following reaction formula, and becomes electrolyzed water 110 containing hydrogen and sodium hypochlorite.
ＮａＣｌ＋Ｈ２Ｏ→ＮａＯＣｌ＋Ｈ２ NaCl + H2O → NaOCl + H2
なお、次亜塩素酸ナトリウムは水溶液中では下記式のようにイオン化して存在している。 In addition, sodium hypochlorite exists in an aqueous solution in an ionized form as shown in the following formula:
ＮａＯＣｌ→Ｎａ＋＋ＯＣｌ－ NaOCl → Na + +OCl -
無隔膜電解では、食塩水を電解した場合、電解水のｐＨは、実際には多少アルカリ側に傾くが、電解前の食塩水と同じｐＨになる。次亜塩素酸は、ｐＨにより優位となる化学種が異なる。すなわち、有効塩素比率（％）（化学種として有効な塩素化合物の比率）を縦軸とし、ｐＨを横軸とした図３に示すように、ｐＨ７．５付近を境に酸性側では殺菌力の高い次亜塩素酸（ＨＯＣｌ）が優位となる一方、アルカリ性側では殺菌力が次亜塩素酸の１００分の１程度と大幅に低下する次亜塩素酸イオン（ＯＣｌ－）が優位となる。しかし、ｐＨが４以下になると猛毒の塩素が生成され安全性が損なわれる。そのため、殺菌力を強めたい場合は、給水タンク中の食塩水のｐＨを弱酸性から中性、具体的には５～７．５に調製することが望ましい。ｐＨの調整には、塩酸又はクエン酸等の酸を添加することが望ましい。 In the case of electrolysis without a diaphragm, when saline is electrolyzed, the pH of the electrolyzed water actually leans slightly toward the alkaline side, but it is the same pH as the saline before electrolysis. Different chemical species of hypochlorous acid are dominant depending on the pH. That is, as shown in FIG. 3, in which the effective chlorine ratio (%) (the ratio of chlorine compounds effective as a chemical species) is on the vertical axis and the pH is on the horizontal axis, hypochlorous acid (HOCl) with high bactericidal power is dominant on the acidic side around pH 7.5, while hypochlorite ions (OCl − ), whose bactericidal power is significantly reduced to about 1/100 of hypochlorous acid, are dominant on the alkaline side. However, when the pH is 4 or less, highly toxic chlorine is generated and safety is compromised. Therefore, if you want to strengthen the bactericidal power, it is desirable to adjust the pH of the saline in the water supply tank from weakly acidic to neutral, specifically 5 to 7.5. To adjust the pH, it is desirable to add an acid such as hydrochloric acid or citric acid.
この第１流路４１を通って霧化部６０に至った電気分解水１１０は、水素及び次亜塩素酸を含有したまま霧化される。これにより、霧化されたミストとともに、水素及び次亜塩素酸は空気中に放出される。この次亜塩素酸により、室内の殺菌及び消臭効果が期待される。もちろん、水素による健康上のメリットも期待される。 The electrolyzed water 110 that passes through this first flow path 41 and reaches the atomization section 60 is atomized while still containing hydrogen and hypochlorous acid. As a result, hydrogen and hypochlorous acid are released into the air along with the atomized mist. This hypochlorous acid is expected to have a sterilizing and deodorizing effect indoors. Of course, hydrogen is also expected to have health benefits.
図４は、本実施形態の水素供給加湿器１０において、電気分解水１１０の流れが流路切替部４０で第２流路４２に切り替えられている状態を示す。食塩水１００が電気分解により水素及び次亜塩素酸を含有する電気分解水１１０となるのは図２の場合と同様である。この第２流路４２を通って濾過部５０に至った電気分解水１１０は、濾過部５０内の吸着剤で次亜塩素酸が除去され、電気分解産物としては水素のみを含有する水素含有水１２０となる。水素含有水１２０は第３流路４３を通って、合流部４４を経て霧化部６０に至る。霧化部６０に至った水素含有水１２０は、水素を含有したまま霧化される。これにより、霧化されたミストとともに、水素は空気中に放出される。この水素により、健康上のメリットも期待される。 Figure 4 shows the state in which the flow of the electrolyzed water 110 is switched to the second flow path 42 by the flow path switching unit 40 in the hydrogen supply humidifier 10 of this embodiment. As in the case of Figure 2, the salt water 100 is electrolyzed to become the electrolyzed water 110 containing hydrogen and hypochlorous acid. The electrolyzed water 110 that reaches the filtration unit 50 through this second flow path 42 has hypochlorous acid removed by the adsorbent in the filtration unit 50, and becomes the hydrogen-containing water 120 containing only hydrogen as the electrolysis product. The hydrogen-containing water 120 passes through the third flow path 43 and reaches the atomization unit 60 through the junction unit 44. The hydrogen-containing water 120 that reaches the atomization unit 60 is atomized while still containing hydrogen. As a result, hydrogen is released into the air along with the atomized mist. This hydrogen is also expected to have health benefits.
以上のとおり、空気中から水素を容易に生活の中で体内に取り入れることができるとともに、流路切替部４０で第１流路４１が選択されている場合には、同時に室内の空気の殺菌及び消臭もできる。さらに、室内に人がいる際には流路切替部４０で第２流路４２を選択して次亜塩素酸が除去された水素のみを、塩素臭のないミストとともに空気中に放出することができる。一方、室内が無人の際には流路切替部４０で第１流路４１を選択して、水素とともに次亜塩素酸を空気中に放出して室内の空気の殺菌及び消臭を行っておくことも可能になる。 As described above, hydrogen can be easily taken into the body from the air during daily life, and when the first flow path 41 is selected by the flow path switching unit 40, the air in the room can be sterilized and deodorized at the same time. Furthermore, when there is someone in the room, the flow path switching unit 40 can select the second flow path 42, and only hydrogen from which hypochlorous acid has been removed can be released into the air along with a mist that does not have a chlorine odor. On the other hand, when there is no one in the room, the flow path switching unit 40 can select the first flow path 41, and hypochlorous acid can be released into the air along with hydrogen, thereby sterilizing and deodorizing the air in the room.
以上のとおり、本実施形態の水素供給加湿器１０は、流路切替部４０による流路の切替により、次亜塩素酸が除去された水素を含んで健康効果が期待されるミストと、水素とともに次亜塩素酸を含むことで殺菌及び消臭効果が期待されるミストとの、性質の違うミストを場合に応じて選択することができる。 As described above, the hydrogen supply humidifier 10 of this embodiment can select mist with different properties depending on the situation, by switching the flow path using the flow path switching unit 40, between mist that contains hydrogen from which hypochlorous acid has been removed and is expected to have health benefits, and mist that contains hypochlorous acid together with hydrogen and is expected to have sterilizing and deodorizing effects.
（２）第２の実施形態
図５は、第２の実施形態の水素供給加湿器１０の概要を示す模式図である。第２の実施形態は、給水タンク２０の中に電気分解部３０が設けられていて、給水タンク２０の中で食塩水１００が電気分解され、給水タンク２０からは電気分解水１１０が直接流出する点で第１の実施形態と異なる。電気分解の機構、流路切替部４０による第１流路４１及び第２流路４２の切替、濾過部５０における次亜塩素酸の除去、及び霧化部６０における電気分解水１１０及び水素含有水１２０の霧化については、第１の実施形態と同様であり、その作用効果についてもまた同様であるので、説明は割愛する。
(2) Second embodiment Fig. 5 is a schematic diagram showing an overview of the hydrogen supply humidifier 10 of the second embodiment. The second embodiment differs from the first embodiment in that an electrolysis unit 30 is provided in a water supply tank 20, a saline solution 100 is electrolyzed in the water supply tank 20, and electrolyzed water 110 flows directly from the water supply tank 20. The mechanism of electrolysis, switching between the first flow path 41 and the second flow path 42 by the flow path switching unit 40, removal of hypochlorous acid in the filtration unit 50, and atomization of the electrolyzed water 110 and the hydrogen-containing water 120 in the atomization unit 60 are the same as those in the first embodiment, and the effects thereof are also the same, so a description thereof will be omitted.
本実施形態では、給水タンク２０の外部に電気分解部３０を設ける必要がないため、装置全体をコンパクトに設計することができる、という利点がある。 In this embodiment, there is no need to provide an electrolysis unit 30 outside the water supply tank 20, which has the advantage that the entire device can be designed compactly.
（３）その他
上記各実施形態においては、食塩水１００の電気分解は無隔膜電解により行われる。この無隔膜電解には、電解槽においてイオン交換膜を隔てて陽極及び陰極を配し、電気分解を行った後、陽極水と陰極水とを互いに混合する方法を含むこととしてもよい。
(3) Others In each of the above embodiments, electrolysis of the saline solution 100 is performed by diaphragm-free electrolysis. This diaphragm-free electrolysis may include a method in which an anode and a cathode are disposed across an ion exchange membrane in an electrolytic cell, and after electrolysis, the anode water and the cathode water are mixed together.
