The air A <b> 1 is supplied to the internal space of the first storage tank 211 through the first air introduction flow path 30 by the blower 212.
　ノズル２１３は、第１貯留槽２１１の内部空間の上部に配置されている。後述する霧化再生部２４によって再生された後、第２液体吸湿材輸送流路２５を介して吸湿部２１に戻された液体吸湿材Ｗ１は、ノズル２１３から第１貯留槽２１１の内部空間に流下し、この際に液体吸湿材Ｗ１と空気Ａ１とが接触する。この種の液体吸湿材Ｗ１と空気Ａ１との接触の形態は、一般に「流下方式」と呼ばれる。なお、液体吸湿材Ｗ１と空気Ａ１との接触形態は、流下方式に限らず、他の方式を用いることができる。例えば第１貯留槽２１１に貯留された液体吸湿材Ｗの中に空気Ａ１を泡状にして供給する方式、いわゆるバブリング方式を用いることもできる。 The nozzle 213 is disposed in the upper part of the internal space of the first storage tank 211. After being regenerated by the atomization regenerating unit 24 described later, the liquid hygroscopic material W1 returned to the hygroscopic unit 21 via the second liquid hygroscopic material transport channel 25 is transferred from the nozzle 213 to the internal space of the first storage tank 211. At this time, the liquid hygroscopic material W1 and the air A1 come into contact with each other. This type of contact between the liquid hygroscopic material W1 and the air A1 is generally referred to as a “flow-down method”. In addition, the contact form of the liquid hygroscopic material W1 and the air A1 is not limited to the flow-down method, and other methods can be used. For example, a so-called bubbling method in which air A1 is supplied in the form of foam into the liquid hygroscopic material W stored in the first storage tank 211 can also be used.
　外部空間に存在する空気Ａ１は、ブロア２１２から第１貯留槽２１１の排出口２１１ａに向かう気流を形成し、ノズル２１３から流れ落ちる液体吸湿材Ｗと接触する。このとき、空気Ａ１中に含まれる水分の少なくとも一部は、液体吸湿材Ｗに吸収されることによって空気Ａ１中から除去される。吸湿部２１では、元々の室内の空気から水分が除去された空気が得られるため、排出口２１１ａから排出される空気Ａ３は、調湿装置２０の外部空間の空気Ａ１よりも乾燥した状態となる。このように、乾燥した空気Ａ３が第１空気排出流路２３を介して筐体２０１の外部に排出される。 The air A1 existing in the external space forms an air flow from the blower 212 toward the discharge port 211a of the first storage tank 211, and comes into contact with the liquid moisture absorbent W flowing down from the nozzle 213. At this time, at least a part of the moisture contained in the air A1 is removed from the air A1 by being absorbed by the liquid moisture absorbent W. In the moisture absorption part 21, air from which moisture has been removed from the original indoor air is obtained, so the air A <b> 3 discharged from the discharge port 211 a is in a state of being drier than the air A <b> 1 in the external space of the humidity controller 20. . Thus, the dried air A3 is discharged to the outside of the housing 201 through the first air discharge channel 23.
　液体吸湿材Ｗは、水分を吸収する性質（吸湿性）を示す液体であり、例えば温度が２５℃、相対湿度が５０％、大気圧下の条件で吸湿性を示す液体が好ましい。液体吸湿材Ｗは、後述する吸湿性物質を含んでいる。また、液体吸湿材Ｗは、吸湿性物質と溶媒とを含んでいてもよい。この種の溶媒としては、吸湿性物質を溶解させる、または吸湿性物質と混和する溶媒が挙げられ、例えば水が挙げられる。吸湿性物質は、有機材料であってもよいし、無機材料であってもよい。 The liquid hygroscopic material W is a liquid exhibiting a property of absorbing moisture (hygroscopicity). For example, a liquid that exhibits hygroscopicity under conditions of a temperature of 25 ° C., a relative humidity of 50%, and atmospheric pressure is preferable. The liquid hygroscopic material W contains a hygroscopic substance to be described later. The liquid hygroscopic material W may contain a hygroscopic substance and a solvent. Examples of this type of solvent include a solvent that dissolves the hygroscopic substance or is miscible with the hygroscopic substance, for example, water. The hygroscopic substance may be an organic material or an inorganic material.
　吸湿性物質として用いられる有機材料としては、例えば２価以上のアルコール、ケトン、アミド基を有する有機溶媒、糖類、保湿化粧品などの原料として用いられる公知の材料などが挙げられる。それらの中でも、親水性が高いことから、吸湿性物質として好適に用いられる有機材料としては、２価以上のアルコール、アミド基を有する有機溶媒、糖類、保湿化粧品等の原料として用いられる公知の材料が挙げられる。 Examples of the organic material used as the hygroscopic substance include known materials used as raw materials for dihydric or higher alcohols, ketones, organic solvents having an amide group, sugars, moisturizing cosmetics, and the like. Among them, known organic materials that are used as raw materials for dihydric or higher alcohols, organic solvents having an amide group, saccharides, moisturizing cosmetics, and the like because of their high hydrophilicity. Is mentioned.
　２価以上のアルコールとしては、例えばグリセリン、プロパンジオール、ブタンジオール、ペンタンジオール、トリメチロールプロパン、ブタントリオール、エチレングリコール、ジエチレングリコール、トリエチレングリコールなどが挙げられる。 Examples of the divalent or higher alcohol include glycerin, propanediol, butanediol, pentanediol, trimethylolpropane, butanetriol, ethylene glycol, diethylene glycol, and triethylene glycol.
　アミド基を有する有機溶媒としては、例えばホルムアミド、アセトアミドなどが挙げられる。 Examples of the organic solvent having an amide group include formamide and acetamide.
　糖類としては、例えばスクロース、プルラン、グルコース、キシロール、フラクトース、マンニトール、ソルビトールなどが挙げられる。 Examples of the saccharide include sucrose, pullulan, glucose, xylol, fructose, mannitol, sorbitol and the like.
　保湿化粧品などの原料として用いられる公知の材料としては、例えば２－メタクリロイルオキシエチルホスホリルコリン（ＭＰＣ）、ベタイン、ヒアルロン酸、コラーゲンなどが挙げられる。 Examples of known materials used as raw materials for moisturizing cosmetics include 2-methacryloyloxyethyl phosphorylcholine (MPC), betaine, hyaluronic acid, collagen, and the like.
　吸湿性物質として用いられる無機材料としては、例えば塩化カルシウム、塩化リチウム、塩化マグネシウム、塩化カリウム、塩化ナトリウム、塩化亜鉛、塩化アルミニウム、臭化リチウム、臭化カルシウム、臭化カリウム、水酸化ナトリウム、ピロリドンカルボン酸ナトリウムなどが挙げられる。 Examples of inorganic materials used as hygroscopic substances include calcium chloride, lithium chloride, magnesium chloride, potassium chloride, sodium chloride, zinc chloride, aluminum chloride, lithium bromide, calcium bromide, potassium bromide, sodium hydroxide, pyrrolidone. Examples thereof include sodium carboxylate.
　吸湿性物質の親水性が高いと、例えば吸湿性物質の材料と水とを混合させたときに、液体吸湿材Ｗの表面（液面）近傍に吸着される水分子の割合が多くなる。後述する霧化再生部２４では、液体吸湿材Ｗの表面近傍から霧状液滴Ｗ３を発生させ、液体吸湿材Ｗから水分を分離する。そのため、液体吸湿材Ｗの表面近傍に吸着される水分子の割合が多いと、水分を効率的に分離できる点で好ましい。また、液体吸湿材Ｗの表面近傍における吸湿性物質の割合が相対的に少なくなるため、霧化再生部２４での吸湿性物質の損失を抑えられる点で好ましい。 If the hygroscopic substance has high hydrophilicity, for example, when the hygroscopic substance material and water are mixed, the ratio of water molecules adsorbed near the surface (liquid surface) of the liquid hygroscopic material W increases. In an atomization regeneration unit 24 described later, a mist-like droplet W3 is generated from the vicinity of the surface of the liquid moisture absorbent W, and moisture is separated from the liquid moisture absorbent W. Therefore, if the ratio of water molecules adsorbed in the vicinity of the surface of the liquid moisture absorbent W is large, it is preferable in that water can be efficiently separated. Moreover, since the ratio of the hygroscopic substance in the vicinity of the surface of the liquid hygroscopic material W is relatively small, it is preferable in that the loss of the hygroscopic substance in the atomization reproduction unit 24 can be suppressed.
　液体吸湿材Ｗのうち、吸湿部２１での処理に用いられる液体吸湿材Ｗ１に含まれる吸湿性物質の濃度は、特に限定されないが、４０質量％以上であることが好ましい。吸湿性物質の濃度が４０質量％以上である場合、液体吸湿材Ｗ１は、効率良く水分を吸収することができる。 Of the liquid hygroscopic material W, the concentration of the hygroscopic substance contained in the liquid hygroscopic material W1 used for the treatment in the hygroscopic portion 21 is not particularly limited, but is preferably 40% by mass or more. When the concentration of the hygroscopic substance is 40% by mass or more, the liquid hygroscopic material W1 can efficiently absorb moisture.
　液体吸湿材Ｗの粘度は、２５ｍＰａ・ｓ以下であることが好ましい。これにより、後述する霧化再生部２４において、液体吸湿材Ｗの液面に液体吸湿材Ｗの液柱Ｃを生じさせやすい。そのため、液体吸湿材Ｗから効率良く水分を分離することができる。 The viscosity of the liquid hygroscopic material W is preferably 25 mPa · s or less. Thereby, in the atomization reproduction | regeneration part 24 mentioned later, it is easy to produce the liquid column C of the liquid hygroscopic material W on the liquid surface of the liquid hygroscopic material W. Therefore, water can be efficiently separated from the liquid hygroscopic material W.
　図２は、霧化再生部２４の概略構成を示す正面図である。図３は、霧化再生部２４の概略構成を示す平面図である。
　図２および図３に示すように、霧化再生部２４は、第２貯留槽２４１（貯留槽）と、超音波振動子２４４（超音波発生部）と、流速減衰部材２４５と、を備えている。霧化再生部２４は、第１液体吸湿材輸送流路２２を介して吸湿部２１から供給された液体吸湿材Ｗ２に含まれる水分の少なくとも一部を霧化し、液体吸湿材Ｗ２から水分の少なくとも一部を除去することにより液体吸湿材Ｗ２を再生する。 FIG. 2 is a front view illustrating a schematic configuration of the atomization reproduction unit 24. FIG. 3 is a plan view showing a schematic configuration of the atomization reproduction unit 24.
As shown in FIGS. 2 and 3, the atomization regeneration unit 24 includes a second storage tank 241 (storage tank), an ultrasonic transducer 244 (ultrasonic wave generation unit), and a flow velocity attenuation member 245. Yes. The atomization regeneration unit 24 atomizes at least part of the moisture contained in the liquid absorbent material W2 supplied from the moisture absorbent unit 21 via the first liquid absorbent material transport channel 22, and at least part of the moisture from the liquid absorbent material W2 The liquid hygroscopic material W2 is regenerated by removing a part thereof.
　第２貯留槽２４１は、第１液体吸湿材輸送流路２２が接続された給液口２４１ａを有しており、再生すべき液体吸湿材Ｗ２を貯留する。第２貯留槽２４１には、第１液体吸湿材輸送流路２２、第２液体吸湿材輸送流路２５、第２空気導入流路２６、および第２空気排出流路２８が接続されている。また、第２貯留槽２４１は、第２液体吸湿材輸送流路２５が接続された排液口２４１ｂを有しており、再生された液体吸湿材Ｗ１を排液口２４１ｂから排出する。 The second storage tank 241 has a liquid supply port 241a to which the first liquid hygroscopic material transport channel 22 is connected, and stores the liquid hygroscopic material W2 to be regenerated. The second storage tank 241 is connected to the first liquid hygroscopic material transport channel 22, the second liquid hygroscopic material transport channel 25, the second air introduction channel 26, and the second air discharge channel 28. Moreover, the 2nd storage tank 241 has the drainage port 241b to which the 2nd liquid hygroscopic material transport channel 25 was connected, and discharge | releases the regenerated liquid hygroscopic material W1 from the drainage port 241b.
　超音波振動子２４４は、第２貯留槽２４１に設けられ、霧状液滴Ｗ３を発生させるための超音波を発振する。これにより、液体吸湿材Ｗ２に超音波が照射され、液体吸湿材Ｗ２から水分を含む霧状液滴Ｗ３が発生する。超音波振動子２４４から液体吸湿材Ｗ２に超音波が照射される際、超音波の発生条件を調整することにより、液体吸湿材Ｗ２の液面に液体吸湿材Ｗ２の液柱Ｃを生じさせることができる。霧状液滴Ｗ３は、液体吸湿材Ｗ２の液柱Ｃから多く発生する。 The ultrasonic transducer 244 is provided in the second storage tank 241 and oscillates an ultrasonic wave for generating the mist droplet W3. As a result, the liquid hygroscopic material W2 is irradiated with ultrasonic waves, and mist droplets W3 containing water are generated from the liquid hygroscopic material W2. When the ultrasonic wave is applied from the ultrasonic vibrator 244 to the liquid absorbent material W2, the liquid column C of the liquid absorbent material W2 is generated on the liquid surface of the liquid absorbent material W2 by adjusting the generation conditions of the ultrasonic wave. Can do. Many of the mist droplets W3 are generated from the liquid column C of the liquid hygroscopic material W2.
　また、図１に示すように、超音波振動子２４４は、第２貯留槽２４１の底板２４１ｆに対して傾斜して設けられている。超音波振動子２４４の超音波射出面２４４ａの中心から超音波射出面２４４ａに対して垂直な軸を超音波の放射軸Ｊと定義する。超音波振動子２４４が第２貯留槽２４１の底板２４１ｆに対して傾斜していることにより、超音波は、放射軸Ｊが液体吸湿材Ｗ２の液面に対して傾くように、超音波射出面２４４ａから液面に向けて伝播される。これにより、液面で反射した超音波が超音波振動子２４４に戻りにくく、超音波振動子２４４自身が超音波によるダメージを受けにくい。また、放射軸Ｊが傾くことに伴って、液柱Ｃは液面に対して傾くように生成される。 Further, as shown in FIG. 1, the ultrasonic transducer 244 is provided to be inclined with respect to the bottom plate 241 f of the second storage tank 241. An axis perpendicular to the ultrasonic emission surface 244a from the center of the ultrasonic emission surface 244a of the ultrasonic transducer 244 is defined as an ultrasonic radiation axis J. Since the ultrasonic vibrator 244 is inclined with respect to the bottom plate 241f of the second storage tank 241, the ultrasonic wave is emitted from the ultrasonic wave emission surface so that the radial axis J is inclined with respect to the liquid surface of the liquid moisture absorbent W2. Propagated from 244a toward the liquid surface. As a result, the ultrasonic wave reflected by the liquid surface is unlikely to return to the ultrasonic transducer 244, and the ultrasonic transducer 244 itself is not easily damaged by the ultrasonic wave. Further, as the radial axis J is inclined, the liquid column C is generated so as to be inclined with respect to the liquid surface.
　超音波振動子２４４は、給液口２４１ａが設けられた側の超音波射出面２４４ａの端部が高く、排液口２４１ｂが設けられた側の超音波射出面２４４ａの端部が低くなる方向に傾斜している。すなわち、図３に示すように、第２貯留槽２４１を底板２４１ｆの法線方向から見たとき、超音波振動子２４４は、矢印Ｙ１で示す放射軸Ｊが傾斜していることによって液体が液柱を形成して落下する向きと、矢印Ｙ２で示す給液口２４１ａから排液口２４１ｂに向かう液体吸湿材Ｗの流れの向きと、が一致する方向に傾斜している。 In the ultrasonic transducer 244, the end of the ultrasonic emission surface 244a on the side where the liquid supply port 241a is provided is high, and the end of the ultrasonic emission surface 244a on the side where the drainage port 241b is provided is low. It is inclined to. That is, as shown in FIG. 3, when the second storage tank 241 is viewed from the normal direction of the bottom plate 241f, the ultrasonic transducer 244 has a liquid that is liquid because the radial axis J indicated by the arrow Y1 is inclined. The direction of falling by forming a column is inclined in a direction in which the direction of the flow of the liquid hygroscopic material W from the liquid supply port 241a toward the liquid discharge port 241b indicated by the arrow Y2 coincides.
　超音波振動子２４４が上述した向きに傾斜している構成は、超音波振動子２４４が上述した向きと逆向きに傾斜している構成、すなわち、矢印Ｙ１と矢印Ｙ２とが逆向きである場合に比べて、液柱Ｃの乱れが生じにくい点で好ましい。 The configuration in which the ultrasonic transducer 244 is tilted in the above-described direction is a configuration in which the ultrasonic transducer 244 is tilted in the reverse direction, that is, the arrows Y1 and Y2 are in the reverse direction. It is preferable in that the disturbance of the liquid column C is less likely to occur.
　本明細書において、図１に示すように、第２貯留槽２４１に貯留された液体吸湿材Ｗ２のうち、超音波振動子２４４の超音波射出面２４４ａの周縁から超音波射出面２４４ａに垂直な方向に延びる仮想的な面によって囲まれた領域を超音波伝播領域Ｒと称する。例えば超音波射出面２４４ａが円形であったとすると、超音波射出面２４４ａの周縁から超音波射出面２４４ａに垂直な方向に延びる円柱状の領域が超音波伝播領域Ｒである。 In this specification, as shown in FIG. 1, the liquid hygroscopic material W2 stored in the second storage tank 241 is perpendicular to the ultrasonic emission surface 244a from the periphery of the ultrasonic emission surface 244a of the ultrasonic transducer 244. A region surrounded by a virtual plane extending in the direction is referred to as an ultrasonic propagation region R. For example, if the ultrasonic emission surface 244a is circular, a cylindrical region extending in the direction perpendicular to the ultrasonic emission surface 244a from the periphery of the ultrasonic emission surface 244a is the ultrasonic propagation region R.
　図２および図３に示すように、流速減衰部材２４５は、第２貯留槽２４１の内部において、超音波伝播領域Ｒ以外の領域に設けられている。第２貯留槽２４１を底板２４１ｆの法線方向から見たとき、流速減衰部材２４５は、超音波伝播領域Ｒの外側に矩形環状に設けられている。 2 and 3, the flow velocity attenuating member 245 is provided in a region other than the ultrasonic wave propagation region R inside the second storage tank 241. When the second storage tank 241 is viewed from the normal direction of the bottom plate 241f, the flow velocity attenuating member 245 is provided in a rectangular ring shape outside the ultrasonic wave propagation region R.
　流速減衰部材２４５は、第２貯留槽２４１の内部空間と連通する空隙を有する構造体で構成されている。この種の構造体として、多数の空隙を有するスポンジ等の多孔質部材、立体構造を有するメッシュ等が用いられる。流速減衰部材２４５は、超音波伝播領域Ｒ以外の領域に設けられ、第２貯留槽２４１の内部空間と連通する空隙を有することにより、超音波伝播領域Ｒにおける超音波の伝播を許容するとともに、給液口２４１ａから第２貯留槽２４１の内部空間に流入する液体吸湿材Ｗ２の流速を減衰させる。これにより、流速減衰部材２４５を通過した後に超音波伝播領域Ｒを流れる液体吸湿材Ｗ２の流速は、流速減衰部材２４５を通過する前の液体吸湿材Ｗ２の流速に比べて低下する。 The flow velocity attenuating member 245 is configured by a structure having a gap communicating with the internal space of the second storage tank 241. As this type of structure, a porous member such as a sponge having a large number of voids, a mesh having a three-dimensional structure, or the like is used. The flow velocity attenuating member 245 is provided in a region other than the ultrasonic wave propagation region R, and has a gap communicating with the internal space of the second storage tank 241, thereby allowing ultrasonic wave propagation in the ultrasonic wave propagation region R, and The flow rate of the liquid hygroscopic material W2 flowing into the internal space of the second storage tank 241 from the liquid supply port 241a is attenuated. Thereby, the flow velocity of the liquid moisture absorbent W2 flowing through the ultrasonic wave propagation region R after passing through the flow velocity attenuation member 245 is lower than the flow velocity of the liquid absorbent material W2 before passing through the flow velocity attenuation member 245.
　流速減衰部材２４５の空隙のサイズは、２ｍｍ～１０ｍｍ程度であることが好ましい。空隙のサイズが大きすぎると、液体吸湿材Ｗ２が構造体に衝突する頻度が少なく、液体吸湿材Ｗ２の流速を低減させる効果が充分に得られない。また、空隙のサイズが小さすぎると、液体吸湿材Ｗ２の循環が阻害され、十分な循環量を確保できない。 The gap size of the flow velocity attenuating member 245 is preferably about 2 mm to 10 mm. If the size of the gap is too large, the liquid hygroscopic material W2 does not collide with the structure frequently and the effect of reducing the flow rate of the liquid hygroscopic material W2 cannot be obtained sufficiently. On the other hand, if the size of the gap is too small, the circulation of the liquid hygroscopic material W2 is hindered and a sufficient amount of circulation cannot be ensured.
　図１に示すように、第２空気導入流路２６の途中にブロア２４２が設けられている。ブロア２４２は、筐体２０１の外部空間から、第２空気導入流路２６を介して第２貯留槽２４１の内部に空気Ａ１を送り込み、第２貯留槽２４１の内部から、第２空気排出流路２８を介して筐体２０１の外部に流れる気流を発生させる。 As shown in FIG. 1, a blower 242 is provided in the middle of the second air introduction channel 26. The blower 242 feeds air A1 from the outer space of the housing 201 into the second storage tank 241 via the second air introduction flow path 26, and the second air discharge flow path from the inside of the second storage tank 241. An airflow that flows to the outside of the housing 201 via the 28 is generated.
　第２空気排出流路２８は、霧状液滴Ｗ３を含む空気Ａ４を筐体２０１の外部空間に排出し、調湿装置２０の内部から除去する。これにより、液体吸湿材Ｗ２から水分を分離することができる。これにより、液体吸湿材Ｗ２の吸湿性能が再び高まり、液体吸湿材Ｗ１を吸湿部２１に戻して再利用することができる。空気Ａ４は、第２貯留槽２４１の内部で発生した霧状液滴Ｗ３を含んでいるため、筐体２０１の外部空間の空気Ａ１よりも湿っている。このように、加湿された空気Ａ４が第２空気排出流路２８を介して筐体２０１の外部に排出される。 The second air discharge channel 28 discharges the air A4 containing the mist droplets W3 to the external space of the casing 201 and removes it from the inside of the humidity control apparatus 20. Thereby, moisture can be separated from the liquid hygroscopic material W2. Thereby, the hygroscopic performance of the liquid hygroscopic material W2 is increased again, and the liquid hygroscopic material W1 can be returned to the hygroscopic portion 21 and reused. Since the air A4 includes the mist droplets W3 generated inside the second storage tank 241, the air A4 is wetter than the air A1 in the external space of the housing 201. In this manner, the humidified air A4 is discharged to the outside of the housing 201 through the second air discharge channel 28.
　吸湿部２１と霧化再生部２４とは、液体吸湿材Ｗの循環流路を構成する第１液体吸湿材輸送流路２２と第２液体吸湿材輸送流路２５とによって接続されている。第２液体吸湿材輸送流路２５の途中には、液体吸湿材Ｗを循環させるためのポンプ２５２が設けられている。 The hygroscopic part 21 and the atomization regeneration part 24 are connected by a first liquid hygroscopic material transport channel 22 and a second liquid hygroscopic material transport channel 25 that constitute a circulation channel of the liquid hygroscopic material W. A pump 252 for circulating the liquid hygroscopic material W is provided in the middle of the second liquid hygroscopic material transport channel 25.
　第１液体吸湿材輸送流路２２は、水分の少なくとも一部が吸収された液体吸湿材Ｗ２を吸湿部２１から霧化再生部２４に輸送する。第１液体吸湿材輸送流路２２の一端は、第１貯留槽２１１の下部に接続されている。第１貯留槽２１１における第１液体吸湿材輸送流路２２の接続箇所は、第１貯留槽２１１内の液体吸湿材Ｗ１の液面よりも下方に位置している。一方、第１液体吸湿材輸送流路２２の他端は、第２貯留槽２４１の下部に接続されている。第２貯留槽２４１における第１液体吸湿材輸送流路２２の接続箇所は、第２貯留槽２４１内の液体吸湿材Ｗ２の液面よりも下方に位置している。 The first liquid hygroscopic material transport channel 22 transports the liquid hygroscopic material W2 in which at least a part of moisture has been absorbed from the hygroscopic unit 21 to the atomization regeneration unit 24. One end of the first liquid hygroscopic material transport channel 22 is connected to the lower portion of the first storage tank 211. The connection location of the first liquid hygroscopic material transport channel 22 in the first storage tank 211 is located below the liquid level of the liquid hygroscopic material W1 in the first storage tank 211. On the other hand, the other end of the first liquid hygroscopic material transport channel 22 is connected to the lower part of the second storage tank 241. The connection location of the first liquid hygroscopic material transport channel 22 in the second storage tank 241 is located below the liquid level of the liquid hygroscopic material W2 in the second storage tank 241.
　第２液体吸湿材輸送流路２５は、水分が除去されて再生された液体吸湿材Ｗを霧化再生部２４から吸湿部２１に輸送する。第２液体吸湿材輸送流路２５の一端は、第２貯留槽２４１の下部に接続されている。第２貯留槽２４１における第２液体吸湿材輸送流路２５の接続箇所は、第２貯留槽２４１内の液体吸湿材Ｗ２の液面よりも下方に位置している。一方、第２液体吸湿材輸送流路２５の他端は、第１貯留槽２１１の上部に接続されている。第１貯留槽２１１における第２液体吸湿材輸送流路２５の接続箇所は、第１貯留槽２１１内の液体吸湿材Ｗ１の液面よりも上方に位置し、上述のノズル２１３に接続されている。 The second liquid hygroscopic material transport channel 25 transports the liquid hygroscopic material W regenerated by removing moisture from the atomization regenerating unit 24 to the hygroscopic unit 21. One end of the second liquid hygroscopic material transport channel 25 is connected to the lower part of the second storage tank 241. The connection location of the second liquid hygroscopic material transport channel 25 in the second storage tank 241 is located below the liquid level of the liquid hygroscopic material W2 in the second storage tank 241. On the other hand, the other end of the second liquid hygroscopic material transport channel 25 is connected to the upper part of the first storage tank 211. The connection location of the second liquid hygroscopic material transport channel 25 in the first storage tank 211 is located above the liquid surface of the liquid hygroscopic material W1 in the first storage tank 211 and is connected to the nozzle 213 described above. .
　上記では、調湿装置２０において、除湿された空気が吸湿部２１から第１空気排出流路２３を介して排出され、加湿された空気が霧化再生部２４から第２空気排出流路２８を介して排出される、と説明した。湿度調整機能について、本実施形態の調湿装置２０を除湿機能のみを備えた調湿装置とする場合には、例えば第１空気排出流路２３の空気排出口を室内に向けて配置する一方、第２空気排出流路２８の空気排出口を室外に向けて配置した構成とすればよい。もしくは、加湿機能のみを備えた調湿装置とする場合には、例えば第２空気排出流路２８の空気排出口を室内に向けて配置する一方、第１空気排出流路２３の空気排出口を室外に向けて配置した構成とすればよい。また、除湿機能と加湿機能の双方を備えた調湿装置とする場合には、第１空気排出流路２３および第２空気排出流路２８の双方の空気排出口を室内に向けて配置し、制御部４２がいずれの空気排出口から空気を排出するかを制御する構成とすればよい。 In the above, in the humidity control apparatus 20, the dehumidified air is discharged from the hygroscopic unit 21 via the first air discharge channel 23, and the humidified air passes through the second air discharge channel 28 from the atomization regeneration unit 24. It was explained that it was discharged through. As for the humidity adjustment function, when the humidity control device 20 of the present embodiment is a humidity control device having only a dehumidification function, for example, the air discharge port of the first air discharge channel 23 is arranged indoors, What is necessary is just to set it as the structure which has arrange | positioned the air exhaust port of the 2nd air exhaust flow path 28 toward the outdoor side.

What is necessary is just to set it as the structure arrange | positioned toward outdoor. In the case of a humidity control device having both a dehumidifying function and a humidifying function, the air discharge ports of both the first air discharge channel 23 and the second air discharge channel 28 are arranged indoors, What is necessary is just to set it as the structure which controls which control part 42 discharges air from which air discharge port.
　本発明者らは、調湿装置２０において、霧化再生部２４における液体吸湿材Ｗの循環流量と液体吸湿材Ｗの霧化量との関係を測定した結果、循環流量がゼロの場合（液体吸湿材Ｗを循環させない場合）に所定の霧化量が得られたとき、循環流量を増加させると、霧化量が低下する傾向にあることを確認した。このことから、本発明者らは、所望の吸湿性能を達成するのに必要な循環流量を得ようとすると、霧化量が低下して液体吸湿材の再生が不充分になる、すなわち、液体吸湿材の吸湿性能と再生性能とがトレードオフの関係にあることを見出した。 As a result of measuring the relationship between the circulation flow rate of the liquid hygroscopic material W and the atomization amount of the liquid hygroscopic material W in the atomization regeneration unit 24 in the humidity control apparatus 20, When the predetermined atomization amount was obtained in the case where the hygroscopic material W was not circulated), it was confirmed that when the circulation flow rate was increased, the atomization amount tended to decrease. From this, the present inventors try to obtain the circulation flow rate necessary to achieve the desired moisture absorption performance, the atomization amount is reduced and the regeneration of the liquid moisture absorbent becomes insufficient, that is, the liquid It was found that the moisture absorption performance and the regeneration performance of the moisture absorbent material are in a trade-off relationship.
　本発明者らは、循環流量を増加させた際に霧化量が低下する原因は、貯留槽内での液体吸湿材の流速が速いと、超音波振動子から放射される超音波の放射軸が不安定化し、液面に発生する液柱が乱れることにあると想定した。そこで、本発明者らは、所定の循環流量を確保するために液体吸湿材の流れを完全に遮断することなく、液柱の乱れを抑制するため、液体吸湿材の流速を減衰させる作用を有する構造体を貯留槽内に配置する構成に想到した。 The inventors of the present invention have a reason that the atomization amount decreases when the circulation flow rate is increased. When the flow rate of the liquid hygroscopic material in the storage tank is high, the radiation axis of the ultrasonic wave radiated from the ultrasonic vibrator Was destabilized and the liquid column generated on the liquid surface was disturbed. Therefore, the present inventors have the effect of attenuating the flow rate of the liquid hygroscopic material in order to suppress the disturbance of the liquid column without completely blocking the flow of the liquid hygroscopic material in order to ensure a predetermined circulation flow rate. The inventors came up with a configuration in which the structure is disposed in the storage tank.
　本発明者らは、貯留槽内に多孔質構造体を配置するとともに、液体吸湿材の流速を一定にし、構造体の空隙のサイズを変えて液体吸湿材の霧化量を測定する実験を行った。構造体を配置しない比較例の霧化再生部における霧化量を１としたとき、実施例の霧化再生部での霧化量を規格化霧化量と定義する。このとき、空隙のサイズが２ｍｍ～１０ｍｍの構造体を配置したときの規格化霧化量は約１．１～１．２であった。この規格化霧化量は、比較例の霧化再生部において流速をゼロとしたときの規格化霧化量である約１．２と略同等であった。このように、貯留槽内に多孔質構造体を配置することによって、多孔質構造体を配置しない場合に比べて霧化量を増やせることが確認された。 The inventors conducted an experiment in which the porous structure is disposed in the storage tank, the flow rate of the liquid hygroscopic material is made constant, and the atomization amount of the liquid hygroscopic material is measured by changing the size of the voids in the structure. It was. When the atomization amount in the atomization reproduction unit of the comparative example in which the structure is not arranged is 1, the atomization amount in the atomization reproduction unit of the example is defined as a normalized atomization amount. At this time, the normalized atomization amount when a structure having a void size of 2 mm to 10 mm was arranged was about 1.1 to 1.2. This normalized atomization amount was substantially equivalent to about 1.2, which is the normalized atomization amount when the flow velocity was set to zero in the atomization regeneration section of the comparative example. Thus, it was confirmed that the amount of atomization can be increased by disposing the porous structure in the storage tank as compared with the case where the porous structure is not disposed.
　上述したように、本実施形態の調湿装置２０においては、第２貯留槽２４１の内部に流速減衰部材２４５が設けられているため、液体吸湿材Ｗの流速が速い場合に生じる液柱Ｃの乱れが抑制され、所望の霧化量を確保することができる。また、流速減衰部材２４５が多数の空隙を有する構造体から構成されているため、液体吸湿材Ｗの流れが遮断されることはなく、所望の循環流量を確保することができる。さらに、流速減衰部材２４５は、超音波伝播領域Ｒ以外の領域に設けられているため、超音波の伝播を阻害することもない。これにより、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置２０を実現することができる。 As described above, in the humidity control apparatus 20 of the present embodiment, since the flow rate attenuation member 245 is provided inside the second storage tank 241, the liquid column C generated when the flow rate of the liquid hygroscopic material W is high. Disturbance is suppressed and a desired atomization amount can be ensured. In addition, since the flow velocity attenuating member 245 is composed of a structure having a large number of gaps, the flow of the liquid hygroscopic material W is not blocked, and a desired circulating flow rate can be ensured. Furthermore, since the flow velocity attenuating member 245 is provided in a region other than the ultrasonic wave propagation region R, the ultrasonic wave propagation is not hindered. Thereby, the humidity control apparatus 20 which has both the moisture absorption performance and reproduction | regeneration performance of the liquid moisture absorption material W is realizable.

Hereinafter, the humidity control apparatus of 2nd Embodiment is demonstrated using FIG.
The basic configuration of the humidity control apparatus of the second embodiment is the same as that of the first embodiment, and the configuration of the atomization regeneration unit is different from that of the first embodiment. Therefore, in 2nd Embodiment, description of structures other than the atomization reproduction | regeneration part is abbreviate | omitted.
FIG. 4 is a plan view showing a schematic configuration of the atomization reproduction unit 32 of the second embodiment.
In FIG. 4, the same components as those used in the first embodiment are denoted by the same reference numerals, and description thereof is omitted.
　図４に示すように、第２実施形態の霧化再生部３２は、第２貯留槽２４１（貯留槽）と、超音波振動子２４４（超音波発生部）と、流速減衰部材３２５と、を備えている。流速減衰部材３２５は、第２貯留槽２４１の全体にわたって設けられておらず、給液口２４１ａの近傍のみに設けられている。このように、流速減衰部材３２５は、第２貯留槽２４１の内部において、超音波伝播領域Ｒ以外の領域に設けられている。流速減衰部材３２５は、第１実施形態と同様、第２貯留槽２４１の内部空間と連通する空隙を有するスポンジ、メッシュ等の多孔質構造体で構成されている。霧化再生部３２のその他の構成は、第１実施形態と同様である。 As shown in FIG. 4, the atomization regeneration unit 32 of the second embodiment includes a second storage tank 241 (storage tank), an ultrasonic vibrator 244 (ultrasonic wave generation unit), and a flow velocity attenuation member 325. I have. The flow velocity attenuating member 325 is not provided over the entire second storage tank 241, and is provided only in the vicinity of the liquid supply port 241a. Thus, the flow velocity attenuating member 325 is provided in a region other than the ultrasonic wave propagation region R inside the second storage tank 241. Similar to the first embodiment, the flow velocity attenuating member 325 is configured by a porous structure such as a sponge or a mesh having a gap communicating with the internal space of the second storage tank 241. The other structure of the atomization reproduction | regeneration part 32 is the same as that of 1st Embodiment.
　第２実施形態においては、液体吸湿材Ｗが第１液体吸湿材輸送流路２２から第２貯留槽２４１に流入する際に、流速減衰部材３２５が液体吸湿材Ｗの流れの抵抗となり、液体吸湿材Ｗの流速が減衰される。これにより、液体吸湿材Ｗの流れに伴う液柱Ｃの乱れが抑制される。 In the second embodiment, when the liquid hygroscopic material W flows from the first liquid hygroscopic material transport channel 22 into the second storage tank 241, the flow velocity attenuation member 325 becomes a resistance to the flow of the liquid hygroscopic material W, and the liquid hygroscopic material W The flow velocity of the material W is attenuated. Thereby, disorder of the liquid column C accompanying the flow of the liquid hygroscopic material W is suppressed.
　第２実施形態においても、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置を実現できる、といった第１実施形態と同様の効果が得られる。 Also in the second embodiment, the same effect as in the first embodiment can be obtained that a humidity control apparatus having both the moisture absorption performance and the regeneration performance of the liquid moisture absorbent W can be realized.
　また、第２実施形態の場合、給液口２４１ａの近傍のみに設けられた流速減衰部材３２５のみで第１実施形態と同等の液柱の乱れを抑制する効果が得られるのであれば、流速減衰部材３２５の使用量を第１実施形態よりも減らすことができる。 In the case of the second embodiment, if only the flow velocity attenuating member 325 provided only in the vicinity of the liquid supply port 241a can obtain the same effect of suppressing the disturbance of the liquid column as that of the first embodiment, the flow velocity is attenuated. The usage amount of the member 325 can be reduced as compared with the first embodiment.

Hereinafter, the humidity control apparatus of 3rd Embodiment is demonstrated using FIG.
The basic configuration of the humidity control apparatus of the third embodiment is the same as that of the first embodiment, and the configuration of the atomization regeneration unit is different from that of the first embodiment. Therefore, in 3rd Embodiment, description of structures other than the atomization reproduction | regeneration part is abbreviate | omitted.
FIG. 5 is a plan view illustrating a schematic configuration of the atomization reproduction unit 34 of the third embodiment.
In FIG. 5, the same reference numerals are given to the same components as those used in the first embodiment, and the description thereof is omitted.
　図５に示すように、第３実施形態の霧化再生部３４は、第２貯留槽２４１（貯留槽）と、超音波振動子２４４（超音波発生部）と、流速減衰部材３４３と、を備えている。流速減衰部材３４３は、超音波伝播領域Ｒ以外の領域に設けられ、第２貯留槽２４１を底板２４１ｆの法線方向から見たとき、超音波伝播領域Ｒの外側に矩形環状に設けられている。 As illustrated in FIG. 5, the atomization reproduction unit 34 of the third embodiment includes a second storage tank 241 (storage tank), an ultrasonic vibrator 244 (ultrasonic wave generation unit), and a flow velocity attenuation member 343. I have. The flow velocity attenuating member 343 is provided in a region other than the ultrasonic wave propagation region R, and is provided in a rectangular ring shape outside the ultrasonic wave propagation region R when the second storage tank 241 is viewed from the normal direction of the bottom plate 241f. .
　流速減衰部材３４３は、第１流速減衰部材３４１と、第２流速減衰部材３４２と、から構成されている。第２貯留槽２４１を底板２４１ｆの法線方向から見たとき、第１流速減衰部材３４１は、超音波伝播領域Ｒに近い側に矩形環状に設けられている。第２流速減衰部材３４２は、第１流速減衰部材３４１の外側に矩形環状に設けられている。第１流速減衰部材３４１および第２流速減衰部材３４２は、第２貯留槽２４１の内部空間と連通する空隙を有するスポンジ、メッシュ等の構造体で構成されている。第１流速減衰部材３４１と第２流速減衰部材３４２とは、異なる材料からなる構造体で構成されていてもよい。 The flow velocity attenuation member 343 includes a first flow velocity attenuation member 341 and a second flow velocity attenuation member 342. When the second storage tank 241 is viewed from the normal direction of the bottom plate 241f, the first flow velocity attenuating member 341 is provided in a rectangular ring shape on the side close to the ultrasonic wave propagation region R. The second flow velocity attenuating member 342 is provided in a rectangular ring shape outside the first flow velocity attenuating member 341. The first flow velocity attenuating member 341 and the second flow velocity attenuating member 342 are configured by a structure such as a sponge or a mesh having a gap communicating with the internal space of the second storage tank 241. The first flow velocity attenuating member 341 and the second flow velocity attenuating member 342 may be composed of structures made of different materials.
　単位体積あたりの構造体に含まれる空隙の体積の割合を流速減衰部材の空隙率と定義する。第１流速減衰部材３４１と第２流速減衰部材３４２とは、構造体の材質が同じであるか否かにかかわらず、空隙率は互いに異なっている。具体的に、第１流速減衰部材３４１の空隙率は、第２流速減衰部材３４２の空隙率よりも小さい。すなわち、流速減衰部材３４３を構成する構造体は、互いに異なる空隙率を有する複数の領域を有しており、超音波伝播領域Ｒに相対的に近い位置の領域の空隙率は、超音波伝播領域Ｒから相対的に遠い位置の領域の空隙率よりも高い。したがって、液体吸湿材Ｗの流れに対して、第１流速減衰部材３４１の抵抗は、第２流速減衰部材３４２の抵抗よりも大きい。霧化再生部３４のその他の構成は、第１実施形態と同様である。 The ratio of the void volume contained in the structure per unit volume is defined as the void ratio of the flow velocity attenuating member. The first flow velocity attenuation member 341 and the second flow velocity attenuation member 342 have different void ratios regardless of whether or not the material of the structure is the same. Specifically, the porosity of the first flow velocity attenuation member 341 is smaller than the porosity of the second flow velocity attenuation member 342. That is, the structure constituting the flow velocity attenuating member 343 has a plurality of regions having mutually different void ratios, and the void ratio in the region relatively close to the ultrasonic wave propagation region R is the ultrasonic wave propagation region. It is higher than the porosity of the region relatively far from R. Therefore, the resistance of the first flow velocity attenuation member 341 is greater than the resistance of the second flow velocity attenuation member 342 with respect to the flow of the liquid hygroscopic material W. The other structure of the atomization reproduction | regeneration part 34 is the same as that of 1st Embodiment.
　第３実施形態においても、流速減衰部材３４３の作用によって液体吸湿材Ｗの流速が減衰され、液柱Ｃの乱れが抑制される。これにより、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置を実現できる、といった第１実施形態と同様の効果が得られる。 Also in the third embodiment, the flow velocity of the liquid hygroscopic material W is attenuated by the action of the flow velocity damping member 343, and the disturbance of the liquid column C is suppressed. Thereby, the effect similar to 1st Embodiment that the humidity control apparatus which has both the moisture absorption performance and reproduction | regeneration performance of the liquid moisture absorption material W is realizable is acquired.
　特に第３実施形態の場合、超音波伝播領域Ｒに近い側にある第１流速減衰部材３４１の空隙率が超音波伝播領域Ｒから遠い側にある第２流速減衰部材３４２の空隙率よりも小さいため、液体吸湿材Ｗの流れが超音波伝播領域Ｒに近付く程、流速が減衰される程度が大きくなる。これにより、流速減衰部材３４３は、超音波伝播領域Ｒから外れた経路を流れる液体吸湿材Ｗの流速をそれ程低減させることなく、超音波伝播領域Ｒに向かう経路を通る液体吸湿材Ｗの流速を十分に低減させることができる。 Particularly in the case of the third embodiment, the porosity of the first flow velocity attenuation member 341 on the side closer to the ultrasonic propagation region R is smaller than the porosity of the second flow velocity attenuation member 342 on the side far from the ultrasonic propagation region R. Therefore, the closer the flow of the liquid hygroscopic material W is to the ultrasonic wave propagation region R, the greater the degree to which the flow velocity is attenuated. As a result, the flow velocity attenuating member 343 reduces the flow velocity of the liquid moisture absorbent material W passing through the path toward the ultrasonic wave propagation region R without significantly reducing the flow velocity of the liquid moisture absorbent material W flowing through the route away from the ultrasonic wave propagation region R. It can be sufficiently reduced.

　図６に示すように、第４実施形態の調湿装置２７は、吸湿部２１と、霧化再生部２９と、第１液体吸湿材輸送流路２２と、第２液体吸湿材輸送流路２５と、第１空気導入流路３０と、第２空気導入流路２６と、第１空気排出流路２３と、第２空気排出流路２８と、制御部４２と、を備えている。霧化再生部２９以外の調湿装置２７の構成は、第１実施形態と同様である。 As shown in FIG. 6, the humidity control apparatus 27 according to the fourth embodiment includes a moisture absorption unit 21, an atomization regeneration unit 29, a first liquid moisture absorbent transport channel 22, and a second liquid moisture absorbent transport channel 25. A first air introduction flow path 30, a second air introduction flow path 26, a first air discharge flow path 23, a second air discharge flow path 28, and a control unit 42. The configuration of the humidity control device 27 other than the atomization regeneration unit 29 is the same as that of the first embodiment.
　図７および図８に示すように、霧化再生部２９は、第２貯留槽２４１（貯留槽）と、超音波振動子２４４（超音波発生部）と、流速減衰部材２９１と、を備えている。流速減衰部材２９１以外の霧化再生部２９の構成は、第１実施形態と同様である。 As shown in FIGS. 7 and 8, the atomization regeneration unit 29 includes a second storage tank 241 (storage tank), an ultrasonic transducer 244 (ultrasonic wave generation unit), and a flow velocity attenuation member 291. Yes. The structure of the atomization reproduction | regeneration part 29 other than the flow velocity attenuation | damping member 291 is the same as that of 1st Embodiment.
　流速減衰部材２９１は、給液口２４１ａと超音波伝播領域Ｒとを結ぶ液体吸湿材Ｗの流れと交差する方向に板面を向けて設けられた板体で構成されている。板体は、第２貯留槽２４１の内壁面から間隔をおいて設けられている。本実施形態において、流速減衰部材２９１は、給液口２４１ａが設けられた側の第２貯留槽２４１の側板２４１ｃと平行に設けられている。ただし、流速減衰部材２９１は、側板２４１ｃに対して傾いて設けられていてもよい。また、流速減衰部材２９１を構成する板体の材質、形状、寸法等は特に限定されない。 The flow velocity attenuating member 291 is configured by a plate body provided with the plate surface facing in the direction intersecting with the flow of the liquid moisture absorbent W connecting the liquid supply port 241a and the ultrasonic wave propagation region R. The plate body is provided at a distance from the inner wall surface of the second storage tank 241. In the present embodiment, the flow velocity attenuating member 291 is provided in parallel with the side plate 241c of the second storage tank 241 on the side where the liquid supply port 241a is provided. However, the flow velocity attenuating member 291 may be provided to be inclined with respect to the side plate 241c. Further, the material, shape, dimensions, etc. of the plate constituting the flow velocity attenuating member 291 are not particularly limited.
　流速減衰部材２９１は、超音波伝播領域Ｒ以外の領域に設けられていることにより、超音波伝播領域Ｒにおける超音波の伝播を許容するとともに、液体吸湿材Ｗの流速を減衰させる。 The flow velocity attenuating member 291 is provided in a region other than the ultrasonic wave propagation region R, thereby allowing the ultrasonic wave to propagate in the ultrasonic wave propagation region R and attenuating the flow rate of the liquid hygroscopic material W.
　第４実施形態の場合、流速減衰部材２９１が給液口２４１ａと超音波伝播領域Ｒとを結ぶ液体吸湿材Ｗの流れと交差するように設けられているため、液体吸湿材Ｗの流れを破線の矢印Ｙ２で示したように、第２貯留槽２４１に流入した液体吸湿材Ｗは、流速減衰部材２９１に衝突した後、流速減衰部材２９１の外側を回り込み、流速減衰部材２９１と第２貯留槽２４１の内壁面との間の間隙から排液口２４１ｂに向かって流れる。このように、流速減衰部材２９１によって液体吸湿材Ｗの流速が減衰され、液柱Ｃの乱れが抑制される。 In the case of the fourth embodiment, the flow velocity attenuating member 291 is provided so as to intersect the flow of the liquid hygroscopic material W connecting the liquid supply port 241a and the ultrasonic wave propagation region R. As indicated by the arrow Y2, the liquid hygroscopic material W that has flowed into the second storage tank 241 collides with the flow velocity attenuation member 291 and then wraps around the outside of the flow velocity attenuation member 291 so that the flow velocity attenuation member 291 and the second storage tank It flows toward the drainage port 241b from the gap between the inner wall surface of 241. Thus, the flow velocity of the liquid hygroscopic material W is attenuated by the flow velocity attenuating member 291 and the disturbance of the liquid column C is suppressed.
　第４実施形態においても、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置２７を実現できる、といった第１実施形態と同様の効果が得られる。 Also in the fourth embodiment, the same effect as in the first embodiment can be obtained that the humidity control device 27 having both the moisture absorption performance and the regeneration performance of the liquid moisture absorbent W can be realized.

Hereinafter, the humidity control apparatus of 5th Embodiment is demonstrated using FIG.
The basic configuration of the humidity control apparatus of the fifth embodiment is the same as that of the first embodiment, and the configuration of the atomization regeneration unit is different from that of the first embodiment. Therefore, in 5th Embodiment, description of structures other than the atomization reproduction | regeneration part is abbreviate | omitted.
FIG. 9 is a plan view illustrating a schematic configuration of the atomization reproduction unit 36 of the fifth embodiment.
In FIG. 9, the same components as those used in the first embodiment are designated by the same reference numerals, and the description thereof is omitted.
　図９に示すように、第５実施形態の霧化再生部３６は、第２貯留槽２４１（貯留槽）と、超音波振動子２４４（超音波発生部）と、流速減衰部材３６１と、を備えている。第４実施形態と同様、流速減衰部材３６１は、給液口２４１ａと超音波伝播領域Ｒとを結ぶ液体吸湿材Ｗの流れと交差する方向に板面を向けて設けられた板体で構成されている。ただし、第４実施形態と異なり、流速減衰部材３６１は、第２貯留槽２４１の内壁面に接して設けられており、両側部３６１ｓに開口部３６１ｈを有している。 As illustrated in FIG. 9, the atomization reproduction unit 36 of the fifth embodiment includes a second storage tank 241 (storage tank), an ultrasonic vibrator 244 (ultrasonic wave generation unit), and a flow velocity attenuation member 361. I have. Similar to the fourth embodiment, the flow velocity attenuating member 361 is configured by a plate body provided with the plate surface facing in a direction intersecting with the flow of the liquid moisture absorbent W connecting the liquid supply port 241a and the ultrasonic wave propagation region R. ing. However, unlike the fourth embodiment, the flow velocity attenuating member 361 is provided in contact with the inner wall surface of the second storage tank 241, and has openings 361h on both sides 361s.
　流速減衰部材３６１を構成する板体の両側部３６１ｓは、複数の孔が設けられたメッシュ状の板材で構成されている。一方、板体の中央部３６１ｃは、孔が設けられていない板体で構成されている。板体の中央部３６１ｃと両側部３６１ｓとは、一体の部材であってもよいし、別体の部材であってもよい。流速減衰部材３６１以外の霧化再生部３６の構成は、第１実施形態と同様である。 Both side portions 361 s of the plate body constituting the flow velocity attenuating member 361 are made of a mesh plate material provided with a plurality of holes. On the other hand, the central part 361c of the plate is configured by a plate that is not provided with a hole. The central part 361c and both side parts 361s of the plate body may be an integral member or separate members. The structure of the atomization reproduction | regeneration part 36 other than the flow velocity attenuation | damping member 361 is the same as that of 1st Embodiment.
　第５実施形態においても、第４実施形態と同様、液体吸湿材Ｗが流速減衰部材３６１の両側部３６１ｓを通して流れることにより、液体吸湿材Ｗの流速が減衰され、液柱Ｃの乱れが抑制される。ただし、第４実施形態では、液体吸湿材Ｗは、流速減衰部材２９１と第２貯留槽２４１の側板との間隙を流れるのに対し、第５実施形態では、液体吸湿材Ｗは、流速減衰部材３６１の両側部３６１ｓの開口部３６１ｈを通して流れる。 Also in the fifth embodiment, as in the fourth embodiment, the liquid hygroscopic material W flows through the both side portions 361s of the flow velocity attenuating member 361, whereby the flow velocity of the liquid hygroscopic material W is attenuated and the disturbance of the liquid column C is suppressed. The However, in the fourth embodiment, the liquid hygroscopic material W flows through the gap between the flow velocity attenuation member 291 and the side plate of the second storage tank 241, whereas in the fifth embodiment, the liquid hygroscopic material W is a flow velocity attenuation member. It flows through the openings 361h on both sides 361s of 361.
　第５実施形態においても、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置を実現できる、といった第１実施形態と同様の効果が得られる。 Also in the fifth embodiment, the same effect as in the first embodiment can be obtained that a humidity control apparatus having both the moisture absorption performance and the regeneration performance of the liquid moisture absorbent W can be realized.
　また、第５実施形態においては、液体吸湿材Ｗが流速減衰部材３６１の両側部３６１ｓの開口部３６１ｈの複数の孔を通して流れるため、第４実施形態に比べて、液体吸湿材Ｗの流れを整流化する効果が高く、流れの乱れが少なくなる。これにより、液柱Ｃの乱れを抑える効果が高まり、霧化効率を向上させることができる。 In the fifth embodiment, since the liquid hygroscopic material W flows through a plurality of holes in the openings 361h of the both side portions 361s of the flow velocity attenuating member 361, the flow of the liquid hygroscopic material W is rectified as compared with the fourth embodiment. Effect is high and less turbulent flow. Thereby, the effect which suppresses disturbance of the liquid column C increases, and the atomization efficiency can be improved.

Hereinafter, the humidity control apparatus of 7th Embodiment is demonstrated using FIG.
The basic configuration of the humidity control apparatus of the seventh embodiment is the same as that of the first embodiment, and the configuration of the atomization regeneration unit is different from that of the first embodiment. Therefore, in 7th Embodiment, description of structures other than the atomization reproduction | regeneration part is abbreviate | omitted.
FIG. 11 is a plan view showing a schematic configuration of the atomization reproduction unit 40 of the seventh embodiment.
In FIG. 11, the same reference numerals are given to the same components as those used in the above embodiment, and the description thereof will be omitted.
　図１１に示すように、第７実施形態の霧化再生部４０は、第２貯留槽２４６（貯留槽）と、複数の超音波振動子２４４（超音波発生部）と、複数の流速減衰部材２９１と、を備えている。 As shown in FIG. 11, the atomization reproduction | regeneration part 40 of 7th Embodiment is the 2nd storage tank 246 (storage tank), several ultrasonic transducer | vibrator 244 (ultrasound generation part), and several flow velocity attenuation | damping member. 291.
　第７実施形態の霧化再生部４０は、複数の超音波振動子２４４を備えているため、超音波振動子２４４の数と等しい数の液柱Ｃが形成され、霧化効率を向上させることができる。図１１に示す霧化再生部４０は６個の超音波振動子２４４を備えているが、超音波振動子２４４の数は６個に限ることなく、適宜変更が可能である。 Since the atomization reproduction unit 40 of the seventh embodiment includes a plurality of ultrasonic transducers 244, the number of liquid columns C equal to the number of ultrasonic transducers 244 is formed, and the atomization efficiency is improved. Can do. The atomization reproduction unit 40 shown in FIG. 11 includes six ultrasonic transducers 244, but the number of ultrasonic transducers 244 is not limited to six and can be changed as appropriate.
　第２貯留槽２４６の内部において、６個の超音波振動子２４４は、３個ずつ２列に配列されている。図１１において、上列の３個の超音波振動子２４４と下列の３個の超音波振動子２４４とは、液柱の落下する向きＹ１が逆向きに傾斜するように設置されている。すなわち、上列の３個の超音波振動子２４４は、液柱の落下する向きＹ１が下側を向くように設置されている。下列の３個の超音波振動子２４４は、液柱の落下する向きＹ１が上側を向くように設置されている。 In the second storage tank 246, six ultrasonic transducers 244 are arranged in two rows of three. In FIG. 11, three ultrasonic transducers 244 in the upper row and three ultrasonic transducers 244 in the lower row are installed such that the direction Y1 in which the liquid column falls is inclined in the opposite direction. That is, the three ultrasonic transducers 244 in the upper row are installed such that the direction Y1 in which the liquid column falls is directed downward. The three ultrasonic transducers 244 in the lower row are installed such that the direction Y1 in which the liquid column falls is directed upward.
　また、上列の３個の超音波振動子２４４と下列の３個の超音波振動子２４４とは、液体吸湿材Ｗの流れ方向Ｙ２における位置がずれて配置されている。例えば、下列左端の超音波振動子２４４は、流れ方向Ｙ２の位置が上列左端の超音波振動子２４４と上列中央の超音波振動子２４４との間に配置され、下列中央の超音波振動子２４４は、流れ方向Ｙ２の位置が上列中央の超音波振動子２４４と上列右端の超音波振動子２４４との間に配置されている。このように、複数の超音波振動子２４４のうち、一部の超音波振動子２４４と他の超音波振動子２４４とは、超音波により発生する液柱Ｃの落下方向Ｙ１が互いに逆向きとなるように配列されるとともに、液体吸湿材Ｗの流れ方向Ｙ２にずれて配置されている。 Also, the three ultrasonic transducers 244 in the upper row and the three ultrasonic transducers 244 in the lower row are arranged with their positions in the flow direction Y2 of the liquid hygroscopic material W shifted. For example, the ultrasonic transducer 244 at the left end of the lower row is disposed between the ultrasonic transducer 244 at the left end of the upper row and the ultrasonic transducer 244 at the center of the upper row, and the ultrasonic vibration at the center of the lower row. The child 244 is disposed between the ultrasonic transducer 244 at the center of the upper row and the ultrasonic transducer 244 at the right end of the upper row in the flow direction Y2. In this way, among the plurality of ultrasonic transducers 244, some ultrasonic transducers 244 and other ultrasonic transducers 244 have the liquid column C drop direction Y1 generated by the ultrasonic waves opposite to each other. And arranged so as to be shifted in the flow direction Y2 of the liquid hygroscopic material W.
　流速減衰部材２９１は、第４実施形態と同様、給液口２４１ａと超音波伝播領域Ｒとを結ぶ液体吸湿材Ｗの流れと交差する方向に板面を向けて設けられた板体で構成されている。複数の流速減衰部材２９１の各々は、複数の超音波振動子２４４の各々に対応して設けられている。流速減衰部材２９１は、当該流速減衰部材２９１に対応する超音波振動子２４４における液体吸湿材Ｗの流れの上流側に配置されている。 As in the fourth embodiment, the flow velocity attenuating member 291 is configured by a plate body that is provided with the plate surface facing in a direction intersecting with the flow of the liquid moisture absorbent W connecting the liquid supply port 241a and the ultrasonic wave propagation region R. ing. Each of the plurality of flow velocity attenuating members 291 is provided corresponding to each of the plurality of ultrasonic transducers 244. The flow velocity attenuating member 291 is disposed on the upstream side of the flow of the liquid hygroscopic material W in the ultrasonic transducer 244 corresponding to the flow velocity attenuating member 291.
　本実施形態において、流速減衰部材２９１は、給液口２４１ａが設けられた側の第２貯留槽２４１の側板２４１ｃと平行に設けられている。ただし、破線で示したように、流速減衰部材２９１Ａは、液体吸湿材Ｗの流れ方向Ｙ２に沿って側板２４１ｃに対して傾いて設けられていてもよい。また、流速減衰部材２９１を構成する板体の材質、形状、寸法、配置等は特に限定されない。 In this embodiment, the flow velocity attenuating member 291 is provided in parallel with the side plate 241c of the second storage tank 241 on the side where the liquid supply port 241a is provided. However, as indicated by a broken line, the flow velocity attenuating member 291A may be provided to be inclined with respect to the side plate 241c along the flow direction Y2 of the liquid hygroscopic material W. Further, the material, shape, dimensions, arrangement, etc. of the plate constituting the flow velocity attenuating member 291 are not particularly limited.
　流速減衰部材２９１は、超音波伝播領域Ｒ以外の領域に設けられていることにより、超音波伝播領域Ｒにおける超音波の伝播を許容するとともに、液体吸湿材Ｗの流速を減衰させる。 The flow velocity attenuating member 291 is provided in a region other than the ultrasonic wave propagation region R, thereby allowing the ultrasonic wave to propagate in the ultrasonic wave propagation region R and attenuating the flow velocity of the liquid hygroscopic material W.
　第７実施形態においても、液体吸湿材Ｗの吸湿性能と再生性能との双方を兼ね備えた調湿装置を実現できる、といった第１実施形態と同様の効果が得られる。 Also in the seventh embodiment, an effect similar to that of the first embodiment can be obtained, such that a humidity control device having both the moisture absorption performance and the regeneration performance of the liquid moisture absorbent W can be realized.
　また、第７実施形態の場合、液柱の落下する向きＹ１が互いに逆向きの超音波振動子２４４は、液体吸湿材Ｗの流れ方向Ｙ２における位置がずれて配置されているため、液柱Ｃ同士が互いに干渉し合うことがなく、液柱Ｃが安定して形成されやすい。さらに、流速減衰部材２９１が上記のように配置されたことにより、液柱の落下する向きＹ１が互いに逆向きの超音波振動子２４４によって生じる液柱Ｃの落下に起因する乱流が超音波伝播領域Ｒにおける超音波伝播に悪影響を及ぼすことを抑制できる。 Further, in the case of the seventh embodiment, since the ultrasonic vibrators 244 whose liquid column falling directions Y1 are opposite to each other are disposed in a position shifted in the flow direction Y2 of the liquid hygroscopic material W, the liquid column C The liquid columns C do not interfere with each other and the liquid column C is easily formed stably. Further, since the flow velocity attenuating member 291 is arranged as described above, the turbulent flow caused by the drop of the liquid column C caused by the ultrasonic vibrators 244 whose liquid column falling directions Y1 are opposite to each other is ultrasonically propagated. An adverse effect on ultrasonic wave propagation in the region R can be suppressed.
　なお、第７実施形態では、複数の超音波振動子２４４を備えた霧化再生部４０に第４実施形態の流速減衰部材２９１を組み合わせた例を示したが、第５実施形態の流速減衰部材３６１（図９参照）や第６実施形態の流速減衰部材３８１（図１０参照）を組み合わせてもよい。あるいは、複数の超音波振動子２４４を備えた霧化再生部４０に、第１実施形態の流速減衰部材２４５（図２参照）、第２実施形態の流速減衰部材３２５（図４参照）、第３実施形態の流速減衰部材３４３（図５参照）等の多孔質部材からなる流速減衰部材を組み合わせてもよい。 In the seventh embodiment, the example in which the atomization reproducing unit 40 including the plurality of ultrasonic transducers 244 is combined with the flow velocity attenuating member 291 of the fourth embodiment is shown. However, the flow velocity attenuating member of the fifth embodiment is shown. 361 (see FIG. 9) or the flow velocity attenuating member 381 of the sixth embodiment (see FIG. 10) may be combined. Alternatively, the atomization reproduction unit 40 including a plurality of ultrasonic transducers 244 is added to the flow velocity attenuation member 245 (see FIG. 2) of the first embodiment, the flow velocity attenuation member 325 (see FIG. 4) of the second embodiment, A flow velocity attenuating member made of a porous member such as the flow velocity attenuating member 343 (see FIG. 5) of the third embodiment may be combined.
　なお、本発明の技術範囲は上記実施形態に限定されるものではなく、本発明の趣旨を逸脱しない範囲において種々の変更を加えることが可能である。
　例えば第１実施形態の霧化再生部は、流速減衰部材が貯留槽の内部空間と連通する空隙を有する構造体で構成され、第４実施形態の霧化再生部は、流速減衰部材が液体吸湿材の流れと交差する方向に設けられた板体で構成されていた。これに対して、前記構造体と前記板体とが組み合わされた構成の流速減衰部材が用いられてもよい。例えば、第１実施形態の構造体の一部が板体に置き換わっていてもよいし、第４実施形態の板体の両側方が多孔質の構造体に置き換わっていてもよい。 The technical scope of the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention.
For example, the atomization regeneration unit of the first embodiment is configured with a structure in which the flow velocity attenuation member has a gap communicating with the internal space of the storage tank. It was comprised with the board provided in the direction which cross | intersects the flow of material. On the other hand, a flow velocity attenuating member having a configuration in which the structure body and the plate body are combined may be used. For example, a part of the structure of the first embodiment may be replaced with a plate, or both sides of the plate of the fourth embodiment may be replaced with a porous structure.
