　以下、本発明の実施形態の表示装置を、図面を参照しながら説明する。なお、各図面においては、同一又は同等の要素には同一の符号を付し、同一又は同等の要素の重複する説明は必要がなければ繰り返さない。 Hereinafter, the display device according to the embodiment of the present invention will be described with reference to the drawings. In each drawing, the same or equivalent elements are designated by the same reference numerals, and duplicate explanations of the same or equivalent elements are not repeated unless necessary.
　（第１実施形態）
　図１～図６を用いて、第１実施形態に係る洗浄機１を説明する。 (First Embodiment)
The washing machine 1 according to the first embodiment will be described with reference to FIGS. 1 to 6.
　図１は、第１実施形態に係る洗浄機１の構成を説明するための断面模式図である。 FIG. 1 is a schematic cross-sectional view for explaining the configuration of the washing machine 1 according to the first embodiment.
　洗浄機１は、食器などの被洗浄物Ｄを水または洗浄液によって洗浄した後に、被洗浄物Ｄを乾燥させるものである。 The washing machine 1 is for washing the object to be washed D such as tableware with water or a washing liquid, and then drying the object to be washed D.
　（洗浄機１の構成）
　図１に示すように、洗浄機１は、洗浄室２と、吸湿室３と、空気循環機構４とを備える。 (Structure of washing machine 1)
As shown in FIG. 1, the washing machine 1 includes a washing chamber 2, a moisture absorbing chamber 3, and an air circulation mechanism 4.
　〈洗浄室２〉
　洗浄室２では、食器などの被洗浄物Ｄが洗浄される。洗浄室２は、被洗浄物Ｄを載せる棚２０と、被洗浄物Ｄに洗浄液を噴射する洗浄ノズル２１と、洗浄水や洗浄液を貯留する洗浄槽２２と、を備えている。洗浄槽２２とノズル２１とは、洗浄液供給配管２６によって接続されている。洗浄室２２の外部では、洗浄液供給配管２６にポンプ２３が接続されている。洗浄液槽２２の洗浄液は、ポンプ２３の駆動により、洗浄液供給管２６を経由して、洗浄ノズル２１に供給され、洗浄ノズル２１から被洗浄物Ｄに噴射される。 <Washing room 2>
In the washing room 2, the object to be washed D such as tableware is washed. The cleaning chamber 2 includes a shelf 20 on which the object D to be cleaned is placed, a cleaning nozzle 21 that injects the cleaning liquid onto the object D to be cleaned, and a cleaning tank 22 that stores the cleaning water and the cleaning liquid. The cleaning tank 22 and the nozzle 21 are connected by a cleaning liquid supply pipe 26. Outside the cleaning chamber 22, the pump 23 is connected to the cleaning liquid supply pipe 26. The cleaning liquid in the cleaning liquid tank 22 is supplied to the cleaning nozzle 21 via the cleaning liquid supply pipe 26 by the drive of the pump 23, and is ejected from the cleaning nozzle 21 to the object D to be cleaned.
　洗浄液槽２２内には、給湯器（図示せず）から温水供給配管２５を経由して温水が、洗浄液槽２２内へ供給される。このため、洗浄機１では、洗浄水または洗浄液を含む温水により被洗浄物Ｄを洗浄することができる。つまり、温水供給配管２５を流れる温水は、被洗浄物Ｄを洗浄する洗浄液または洗浄水を加熱するために利用される。 In the cleaning liquid tank 22, hot water is supplied from the water heater (not shown) into the cleaning liquid tank 22 via the hot water supply pipe 25. Therefore, in the washing machine 1, the object D to be washed can be washed with washing water or warm water containing a washing liquid. That is, the hot water flowing through the hot water supply pipe 25 is used to heat the cleaning liquid or the cleaning water for cleaning the object D to be cleaned.
　〈吸湿室３〉
　吸湿室３には、タンクのような構造をなしており、吸湿液Ｗが貯留されている。吸湿室３では、吸湿液Ｗにより水分を吸湿する。具体的には、吸湿室３では、洗浄室２から取り込んだ空気中に含まれる水分の少なくとも一部を、吸湿液Ｗによって吸湿する。 <Hygroscopic chamber 3>
The moisture absorbing chamber 3 has a tank-like structure and stores the moisture absorbing liquid W. In the moisture absorbing chamber 3, moisture is absorbed by the moisture absorbing liquid W. Specifically, in the hygroscopic chamber 3, at least a part of the moisture contained in the air taken in from the washing chamber 2 is absorbed by the hygroscopic liquid W.
　吸湿液Ｗは、空気中に含まれる水分を吸湿する液体のことである。吸湿液Ｗは、例えば、グリセリン、塩化リチウム、ポリグリセリン等の吸水高分子、または塩化カルシウム、臭化リチウム等を含む。吸湿液Ｗは上記の成分を１種類のみ含んでいてもよいし、２種以上含んでいてもよい。 The hygroscopic liquid W is a liquid that absorbs the moisture contained in the air. The hygroscopic liquid W contains, for example, a water-absorbing polymer such as glycerin, lithium chloride, or polyglycerin, or calcium chloride, lithium bromide, or the like. The hygroscopic liquid W may contain only one kind of the above-mentioned components, or may contain two or more kinds of the above-mentioned components.
　〈空気循環機構４〉
　空気循環機構４は、洗浄室２内の空気と吸湿室３内の空気とを循環させる。空気循環機構４は、空気循環配管４１と、ファン４２と、第１開閉バルブ４３と、第２開閉バルブ４４とを備える。 <Air circulation mechanism 4>
The air circulation mechanism 4 circulates the air in the cleaning chamber 2 and the air in the moisture absorption chamber 3. The air circulation mechanism 4 includes an air circulation pipe 41, a fan 42, a first on-off valve 43, and a second on-off valve 44.
　空気循環配管４１は、第１空気配管４１ａと、第２空気配管４１ｂとを備える。第１空気配管４１ａは、洗浄室２内の空気が吸湿室３に移送される際に、空気が通過する配管である。第１空気配管４１ａには、第１開閉バルブ４３と、ファン４２とが配されている。第１開閉バルブ４３は、第１空気配管４１ａ内を流れる空気の流路の開閉を行う。 The air circulation pipe 41 includes a first air pipe 41a and a second air pipe 41b. The first air pipe 41a is a pipe through which air passes when the air in the cleaning chamber 2 is transferred to the moisture absorbing chamber 3. A first open / close valve 43 and a fan 42 are arranged in the first air pipe 41a. The first on-off valve 43 opens and closes the flow path of the air flowing in the first air pipe 41a.
　第１バルブ４３が開いているときに、ファン４２が駆動すると、洗浄室２内の空気は、吸湿室３まで送り込まれる。吸湿室３内に送り込まれた空気は、吸湿液Ｗに接触し、その少なくとも一部の水分を除去される。吸湿室３内の水分が除去された空気は、それ自体の圧力が高まることによって、第２空気配管４１ｂに送り出される。 When the fan 42 is driven while the first valve 43 is open, the air in the cleaning chamber 2 is sent to the moisture absorption chamber 3. The air sent into the moisture absorbing chamber 3 comes into contact with the moisture absorbing liquid W, and at least a part of the water is removed. The air from which the moisture in the moisture absorbing chamber 3 has been removed is sent out to the second air pipe 41b by increasing the pressure of itself.
　第２空気配管４１ｂは、吸湿室３内の空気が洗浄室２に返送される際に、空気が通過する配管である。第２空気配管４１ｂには、第２開閉バルブ４４が設けられている。第２開閉バルブ４４は、第２１空気配管４１ｂ内を流れる空気の流路の開閉を行う。 The second air pipe 41b is a pipe through which air passes when the air in the moisture absorbing chamber 3 is returned to the cleaning chamber 2. The second air pipe 41b is provided with a second on-off valve 44. The second on-off valve 44 opens and closes the flow path of the air flowing in the 21st air pipe 41b.
　洗浄機１は、吸湿室３に加熱空気を供給する加熱空気供給部９をさらに備える。加熱空気供給部９は、加熱空気供給配管９ａと、加熱空気供給ファン９ｂと、熱交換器９ｃと、第３開閉バルブ９ｄとを備える。 The washing machine 1 further includes a heated air supply unit 9 that supplies heated air to the moisture absorbing chamber 3. The heated air supply unit 9 includes a heated air supply pipe 9a, a heated air supply fan 9b, a heat exchanger 9c, and a third on-off valve 9d.
　加熱空気供給配管９ａは、その一方が吸湿室３に接続されており、他方が洗浄機１の外部空気に開放されている。このため、加熱空気供給配管９ａは、加熱空気供給ファン９ｂが回転すると、洗浄機１の外部の空気を吸湿室３まで導く。 One of the heated air supply pipes 9a is connected to the moisture absorbing chamber 3, and the other is open to the outside air of the washing machine 1. Therefore, when the heated air supply fan 9b rotates, the heated air supply pipe 9a guides the air outside the washing machine 1 to the moisture absorbing chamber 3.
　熱交換器９ｃは、加熱空気供給配管９ａに設けられている。熱交換器９ｃは、温水供給配管２５内を通過する温水の熱と、洗浄機１の外部から加熱空気供給配管９ａに取り込まれた空気の熱とを熱交換する。より具体的には、温水供給配管２５内の温水の熱が加熱空気供給配管９ａ内の空気に与えられる。これにより、洗浄機１の外部から取り込まれた空気は、例えば、５０℃以上７０℃以下に加熱される。加熱された空気は、加熱空気供給ファン９ｂによって吸湿室３に供給される。 The heat exchanger 9c is provided in the heated air supply pipe 9a. The heat exchanger 9c exchanges heat between the heat of the hot water passing through the hot water supply pipe 25 and the heat of the air taken into the heated air supply pipe 9a from the outside of the washing machine 1. More specifically, the heat of the hot water in the hot water supply pipe 25 is given to the air in the heated air supply pipe 9a. As a result, the air taken in from the outside of the washing machine 1 is heated to, for example, 50 ° C. or higher and 70 ° C. or lower. The heated air is supplied to the moisture absorbing chamber 3 by the heated air supply fan 9b.
　第３開閉バルブ９ｄは、加熱空気供給配管９ａに設けられており、加熱空気供給配管９ａの空気の流路の開閉を行う。 The third on-off valve 9d is provided in the heated air supply pipe 9a and opens and closes the air flow path of the heated air supply pipe 9a.
　＜制御部＞
　本実施の形態においては、前述のポンプ２３、開閉バルブ４３、４４、９ｄ、ファン４２、及び加熱空気供給ファン９ｂは、洗浄の開始を指示するスイッチがＯＮされると、図示されていない制御部によって自動的に制御される。ただし、前述のポンプ２３、開閉バルブ４３、４４、９ｄ、ファン４２、および加熱空気供給ファン９ｂの少なくともいずれかが、人の操作によって制御されるものであってもよい。 <Control unit>
In the present embodiment, the pump 23, the on-off valves 43, 44, 9d, the fan 42, and the heated air supply fan 9b described above are control units (not shown) when the switch instructing the start of cleaning is turned on. Is automatically controlled by. However, at least one of the pump 23, the on-off valves 43, 44, 9d, the fan 42, and the heated air supply fan 9b described above may be controlled by human operation.
　〈洗浄機１の動作〉
　次に図２～図５を用いて、洗浄機１の動作について説明する。 <Operation of washing machine 1>
Next, the operation of the washing machine 1 will be described with reference to FIGS. 2 to 5.
　洗浄機１は、被洗浄物Ｄを洗浄する一連の構成としての予備洗浄工程、本洗浄工程、およびすすぎ工程と、被洗浄物Ｄを乾燥させる乾燥工程と、吸湿室３内の吸湿液Ｗを再生させる吸湿液再生工程と、を有する。 The cleaning machine 1 performs a preliminary cleaning step, a main cleaning step, and a rinsing step as a series of configurations for cleaning the object to be cleaned D, a drying step to dry the object to be cleaned D, and a moisture absorbing liquid W in the moisture absorbing chamber 3. It has a moisture absorbing liquid regeneration step of regenerating.
　本実施形態では、吸湿液再生工程を本洗浄工程と同時に行う例について説明する。ただし、吸湿液再生工程は、本洗浄工程とは別の工程として実行されてもよい。 In this embodiment, an example in which the hygroscopic liquid regeneration step is performed at the same time as the main cleaning step will be described. However, the hygroscopic liquid regeneration step may be executed as a step different from the main cleaning step.
　（予備洗浄工程）
　図２は、本実施形態に係る洗浄機１における予備洗浄工程を説明するための断面模式図である。予備洗浄工程では、被洗浄物Ｄの表面に付着した固形物等の汚れを、洗浄水により洗浄する。 (Preliminary cleaning process)
FIG. 2 is a schematic cross-sectional view for explaining a pre-cleaning step in the washing machine 1 according to the present embodiment. In the pre-cleaning step, dirt such as solid matter adhering to the surface of the object to be cleaned D is washed with cleaning water.
　具体的には、洗浄液槽２２に貯留された洗浄水が、ポンプ２３の駆動によって、洗浄液供給管２６および洗浄ノズル２１を介して被洗浄物Ｄに噴射される。この際、洗浄液槽２２の洗浄水は、給湯器（図示せず）から温水供給配管２５を経由して供給される温水によって加熱される。したがって、加熱された洗浄水が洗浄ノズル２１から被洗浄物Ｄへ吹き付けられる。そのため、被洗浄物Ｄに付着した汚れをより効率的に除去することができる。 Specifically, the cleaning water stored in the cleaning liquid tank 22 is sprayed onto the object to be cleaned D via the cleaning liquid supply pipe 26 and the cleaning nozzle 21 by the drive of the pump 23. At this time, the washing water in the washing liquid tank 22 is heated by the hot water supplied from the water heater (not shown) via the hot water supply pipe 25. Therefore, the heated cleaning water is sprayed from the cleaning nozzle 21 onto the object to be cleaned D. Therefore, the dirt adhering to the object to be cleaned D can be removed more efficiently.
　尚、予備洗浄工程では、第１開閉バルブ４３及び第２開閉バルブ４４は閉塞され、ファン４２は停止している。このため、洗浄室２内の水分を含む空気は吸湿室３内に侵入しない。 In the preliminary cleaning step, the first on-off valve 43 and the second on-off valve 44 are closed, and the fan 42 is stopped. Therefore, the air containing moisture in the washing chamber 2 does not enter the moisture absorbing chamber 3.
　（本洗浄工程）
　図３は、本実施形態における本洗浄工程を説明するための断面模式図である。本工程では、洗浄液槽２２内に貯留された洗剤等を含む洗浄液により、予備洗浄された後の被洗浄物Ｄを洗浄する。 (Main cleaning process)
FIG. 3 is a schematic cross-sectional view for explaining the main cleaning step in the present embodiment. In this step, the object to be cleaned D after pre-cleaning is washed with a cleaning liquid containing detergent and the like stored in the cleaning liquid tank 22.
　（吸湿液再生工程）
　本実施形態では、上記本洗浄工程と並行して、吸湿液再生工程を行う。 (Hygroscopic liquid regeneration process)
In the present embodiment, the hygroscopic liquid regeneration step is performed in parallel with the main cleaning step.
　吸湿液再生工程では、吸湿室３内に配された吸湿液Ｗに含まれている水分の少なくとも一部を除去する。 In the hygroscopic liquid regeneration step, at least a part of the water contained in the hygroscopic liquid W arranged in the hygroscopic chamber 3 is removed.
　吸湿液再生工程では、加熱空気供給ファン９ｂを駆動させると共に、第３開閉バルブ９ｄ及び第２開閉バルブ４４を開放する。これにより、洗浄機１外の乾燥した空気が、加熱空気供給ファン９ｂの駆動によって、加熱空気供給配管９ａを介して吸湿室３内に取り込まれる。この際、上述したように、洗浄機１外から取り込まれた空気は、熱交換器９ｃによって加熱される。このため、吸湿室３内には、加熱された空気が供給される。吸湿室３内に取り込まれた空気は、吸湿室３内の吸湿液Ｗと接触する。吸湿液Ｗに含まれている水分の少なくとも一部は、空気に取り込まれる。これにより、吸湿液Ｗに含まれている水分が低減され、吸湿液Ｗが再生される。 In the hygroscopic liquid regeneration step, the heated air supply fan 9b is driven and the third on-off valve 9d and the second on-off valve 44 are opened. As a result, the dry air outside the washing machine 1 is taken into the moisture absorbing chamber 3 via the heated air supply pipe 9a by driving the heated air supply fan 9b. At this time, as described above, the air taken in from the outside of the washing machine 1 is heated by the heat exchanger 9c. Therefore, heated air is supplied to the moisture absorption chamber 3. The air taken into the moisture absorbing chamber 3 comes into contact with the moisture absorbing liquid W in the moisture absorbing chamber 3. At least a part of the water contained in the hygroscopic liquid W is taken into the air. As a result, the water content contained in the hygroscopic liquid W is reduced, and the hygroscopic liquid W is regenerated.
　吸湿液Ｗに含まれている水分の少なくとも一部を取り込んだ空気は、加熱空気供給ファン９ｂの駆動によって、吸湿室３から第２空気配管４１ｂを介して洗浄室２内に移送され、洗浄室２の隙間から外部空間へ放出される。 The air that has taken in at least a part of the moisture contained in the hygroscopic liquid W is transferred from the hygroscopic chamber 3 to the cleaning chamber 2 via the second air pipe 41b by the drive of the heated air supply fan 9b, and is transferred into the cleaning chamber 2. It is discharged from the gap of 2 to the external space.
　上述のように、吸湿室３に送られる空気は、加熱空気供給配管９ａを流れているときに、熱交換器９ｃによって加熱されている。よって、吸湿室３から洗浄室２内に移送される空気も温度が高い。このため、本洗浄を行っている洗浄室２内に熱を付与することができる。 As described above, the air sent to the moisture absorption chamber 3 is heated by the heat exchanger 9c while flowing through the heated air supply pipe 9a. Therefore, the temperature of the air transferred from the moisture absorbing chamber 3 to the cleaning chamber 2 is also high. Therefore, heat can be applied to the inside of the washing chamber 2 where the main washing is performed.
　尚、吸湿液再生工程の際には、第１開閉バルブ４３および第２開閉バルブ４４は閉塞され、ファン４２は停止している。このため、洗浄室２内の水分を含む空気は吸湿室３内に侵入しない。 During the hygroscopic liquid regeneration process, the first on-off valve 43 and the second on-off valve 44 are closed, and the fan 42 is stopped. Therefore, the air containing moisture in the washing chamber 2 does not enter the moisture absorbing chamber 3.
　尚、本実施形態では、吸湿液Ｗの再生に、加熱空気を用いる例について説明したが、本開示の洗浄機はこの構成に限定されない。吸湿液再生工程では、常温の空気を吸湿室３に取り込んでもよい。 In the present embodiment, an example in which heated air is used for the regeneration of the hygroscopic liquid W has been described, but the washing machine of the present disclosure is not limited to this configuration. In the hygroscopic liquid regeneration step, air at room temperature may be taken into the hygroscopic chamber 3.
　（すすぎ工程）
　図４は、本実施形態におけるすすぎ工程を説明するための断面模式図である。本すすぎ工程では、洗浄液槽２２内に、洗浄水が貯留される。洗浄水は、洗浄ノズル２１を介して、被洗浄物Ｄに対して噴射される。これにより、被洗浄物Ｄに付着した洗浄液や汚れの残滓などが洗浄される。 (Rinse process)
FIG. 4 is a schematic cross-sectional view for explaining the rinsing process in the present embodiment. In this rinsing step, the washing water is stored in the washing liquid tank 22. The cleaning water is sprayed onto the object to be cleaned D via the cleaning nozzle 21. As a result, the cleaning liquid and the residue of dirt adhering to the object to be cleaned D are cleaned.
　尚、すすぎ工程においては、第１開閉バルブ４３及び第２開閉バルブ４４は閉塞される。このため、洗浄室２内の空気と吸湿室３内の空気とは循環されない。また、第３開閉バルブ９ｄは閉塞されている。このため、加熱空気は、吸湿室３内に供給されない。 In the rinsing process, the first on-off valve 43 and the second on-off valve 44 are closed. Therefore, the air in the washing chamber 2 and the air in the moisture absorbing chamber 3 are not circulated. Further, the third on-off valve 9d is closed. Therefore, the heated air is not supplied into the moisture absorbing chamber 3.
　（乾燥工程）
　図５は、本実施形態における乾燥工程を説明するための模式図である。本工程では、洗浄室２内の空気を乾燥させることで、被洗浄物Ｄの乾燥を行う。 (Drying process)
FIG. 5 is a schematic diagram for explaining the drying process in the present embodiment. In this step, the object to be cleaned D is dried by drying the air in the cleaning chamber 2.
　乾燥工程では、空気循環機構４の、第１開閉バルブ４３及び第２開閉バルブ４４を開放するとともに、ファン４２を駆動させる。これにより、洗浄室２内の空気と吸湿室３内の空気とを循環させる。すなわち、洗浄室２内の空気は吸湿室３に取り込まれ、吸湿室３内の空気は洗浄室２内に返送される。 In the drying step, the first on-off valve 43 and the second on-off valve 44 of the air circulation mechanism 4 are opened and the fan 42 is driven. As a result, the air in the washing chamber 2 and the air in the moisture absorbing chamber 3 are circulated. That is, the air in the washing chamber 2 is taken into the moisture absorbing chamber 3, and the air in the moisture absorbing chamber 3 is returned to the cleaning chamber 2.
　空気循環機構４によって、吸湿室３に取り込まれた洗浄室２内の空気は、吸湿液Ｗと接触する。吸湿液Ｗと接触した空気中の水分の少なくとも一部は、吸湿液Ｗにより吸湿される。これによって、空気中の水分が低減される。水分が低減された空気は、第２空気配管４１ｂを介して洗浄室２内に返送される。上記循環を複数回繰り返すことにより、洗浄室２内の空気が乾燥し、被洗浄物Ｄが乾燥する。 The air in the cleaning chamber 2 taken into the hygroscopic chamber 3 by the air circulation mechanism 4 comes into contact with the hygroscopic liquid W. At least a part of the moisture in the air in contact with the hygroscopic liquid W is absorbed by the hygroscopic liquid W. This reduces the moisture in the air. The air with reduced water content is returned to the cleaning chamber 2 via the second air pipe 41b. By repeating the above circulation a plurality of times, the air in the washing chamber 2 is dried, and the object D to be washed is dried.
　以上説明したように、洗浄機１では、洗浄室２内の水分を含んだ空気を、吸湿液Ｗにより吸湿する。このため、乾燥剤としてゼオライトなどの固体吸湿材を用いる洗浄機のように、乾燥剤再生用のヒーターを別途設ける必要がない。また、１５０℃もの高温に加熱する必要がなく、省電力化を図ることができる。 As described above, in the washing machine 1, the air containing water in the washing chamber 2 is absorbed by the hygroscopic liquid W. Therefore, unlike a washing machine that uses a solid hygroscopic material such as zeolite as a desiccant, it is not necessary to separately provide a heater for regenerating the desiccant. In addition, it is not necessary to heat the product to a high temperature of 150 ° C., which can save power.
　尚、本実施形態では、本洗浄工程と並行して吸湿液再生工程を行ったが、本開示の洗浄機はこの構成に限定されない。吸湿液再生工程は、すすぎ工程と並行して行ってもよいし、被洗浄物Ｄの洗浄を行っていないとき、つまり、洗浄機１が動作していないときに行ってもよい。 In the present embodiment, the hygroscopic liquid regeneration step is performed in parallel with the main washing step, but the washing machine of the present disclosure is not limited to this configuration. The hygroscopic liquid regeneration step may be performed in parallel with the rinsing step, or may be performed when the object D to be cleaned is not washed, that is, when the washing machine 1 is not operating.
　次に、吸湿室３の構成の一例について詳細に説明する。 Next, an example of the configuration of the moisture absorption chamber 3 will be described in detail.
　図６は、吸湿室３の構成の一例を示す概略図である。 FIG. 6 is a schematic view showing an example of the configuration of the moisture absorption chamber 3.
　図６に示すように、吸湿室３は、吸湿液槽３０と、基材５と、吸湿液供給部３１とを備える。 As shown in FIG. 6, the moisture absorbing chamber 3 includes a moisture absorbing liquid tank 30, a base material 5, and a moisture absorbing liquid supply unit 31.
　吸湿液槽３０は、吸湿液Ｗを収容している。 The hygroscopic liquid tank 30 houses the hygroscopic liquid W.
　基材５は、例えば、複数設けられており、吸湿室３内において、上下に延びるように配されている。複数の基材５のそれぞれは、矩形形状を有するシートにより構成されている。複数の基材５は、互いに間隔をおいて平行に配されている。 A plurality of base materials 5 are provided, for example, and are arranged so as to extend vertically in the moisture absorbing chamber 3. Each of the plurality of base materials 5 is composed of a sheet having a rectangular shape. The plurality of base materials 5 are arranged in parallel at intervals from each other.
　基材５には、吸湿液Ｗが含浸されている。本実施形態では、複数の基材５のそれぞれの下方の一部分が、吸湿液槽３０の吸湿液に浸漬されている。 The base material 5 is impregnated with the hygroscopic liquid W. In the present embodiment, a lower portion of each of the plurality of base materials 5 is immersed in the hygroscopic liquid of the hygroscopic liquid tank 30.
　吸湿液供給部３１は、複数の基材５のそれぞれに、吸湿液槽３０内の吸湿液Ｗを供給する。吸湿液供給部３１は、吸湿液供給配管３１ａと、吸湿液供給ポンプ３１ｂと、吸湿液ノズル３１ｃとを備える。 The hygroscopic liquid supply unit 31 supplies the hygroscopic liquid W in the hygroscopic liquid tank 30 to each of the plurality of base materials 5. The hygroscopic liquid supply unit 31 includes a hygroscopic liquid supply pipe 31a, a hygroscopic liquid supply pump 31b, and a hygroscopic liquid nozzle 31c.
　吸湿液供給配管３１ａは、複数の基材５の上方に配された吸湿液ノズル３１ｃと、吸湿液槽３０とを接続している。吸湿液供給配管３１ａには、吸湿液供給ポンプ３１ｂが設けられている。吸湿液供給ポンプ３１ｂを駆動することにより、吸湿液ノズル３１ｃから吸湿液槽３０内の吸湿液Ｗが、吸湿液ノズル３１ｃから複数の基材５のそれぞれに供給される。これにより、吸湿液Ｗが複数の基材５のそれぞれの全体に接触し続ける。換言すれば、複数の基材５の全体に吸湿液Ｗが含浸された状態が保持される。 The hygroscopic liquid supply pipe 31a connects the hygroscopic liquid nozzles 31c arranged above the plurality of base materials 5 and the hygroscopic liquid tank 30. The hygroscopic liquid supply pipe 31a is provided with a hygroscopic liquid supply pump 31b. By driving the hygroscopic liquid supply pump 31b, the hygroscopic liquid W in the hygroscopic liquid tank 30 is supplied from the hygroscopic liquid nozzle 31c to each of the plurality of base materials 5. As a result, the hygroscopic liquid W continues to be in contact with the entire of each of the plurality of base materials 5. In other words, the state in which the hygroscopic liquid W is impregnated in the entire plurality of base materials 5 is maintained.
　複数の基材５は、吸湿液Ｗを保持できる材料を含んでいれば、その材質は特に限定されない。ただし、基材５は、例えば、貫通孔、開口、または隙間等の、空気が通過できる構造を有する通気性材料または微細な連通孔を有する多孔質材料を含んでいることが好ましい。つまり、基材５は、空気を通過させる通気性部を有していることが好ましい。通気性部を有する基材５としては、例えば、ガラス繊維紙、セラミックペーパー等の材料を用いたハニカムコア材、網目状材料、織布、不織布等が挙げられる。 The material of the plurality of base materials 5 is not particularly limited as long as it contains a material capable of retaining the hygroscopic liquid W. However, it is preferable that the base material 5 contains a breathable material having a structure through which air can pass, such as a through hole, an opening, or a gap, or a porous material having fine communication holes. That is, it is preferable that the base material 5 has a breathable portion through which air can pass. Examples of the base material 5 having a breathable portion include a honeycomb core material using a material such as glass fiber paper and ceramic paper, a mesh-like material, a woven fabric, and a non-woven fabric.
　本実施形態では、複数の基材５に吸湿液Ｗが含浸されている。このため、吸湿室３内に取り込まれた空気と、吸湿液Ｗとの接触面積を大きくすることができる。 In this embodiment, the plurality of base materials 5 are impregnated with the hygroscopic liquid W. Therefore, the contact area between the air taken into the hygroscopic chamber 3 and the hygroscopic liquid W can be increased.
　さらに、本実施形態では、複数の基材５は、通気性部を有しており、吸湿室３内において、上下に延びるように配されている。このため、乾燥工程において、洗浄室２内の水分を含む空気は、吸湿室３へ取り込まれた後、複数の基材５を通過する。換言すれば、空気循環機構４が、洗浄室２から取り込んだ水分を含む空気に複数の基材５の微細な連通孔を通過させる。よって、吸湿室３内に取り込まれた水分を含む空気と、吸湿液Ｗとの接触面積を、より大きくすることができる。従って、洗浄室２内の空気に含まれる水分を効率的に低減することができる。このため、洗浄機１では、乾燥工程に要する時間を、通気性部を含まない場合よりも短縮し得る。 Further, in the present embodiment, the plurality of base materials 5 have a breathable portion and are arranged so as to extend vertically in the moisture absorbing chamber 3. Therefore, in the drying step, the air containing moisture in the washing chamber 2 passes through the plurality of base materials 5 after being taken into the moisture absorbing chamber 3. In other words, the air circulation mechanism 4 allows the water-containing air taken in from the cleaning chamber 2 to pass through the fine communication holes of the plurality of base materials 5. Therefore, the contact area between the water-containing air taken into the hygroscopic chamber 3 and the hygroscopic liquid W can be made larger. Therefore, the moisture contained in the air in the cleaning chamber 2 can be efficiently reduced. Therefore, in the washing machine 1, the time required for the drying step can be shortened as compared with the case where the breathable portion is not included.
　また、本構成を有する吸湿室３であれば、吸湿液再生工程の際に、加熱空気供給部９が、加熱空気に複数の基材５の微細な連通孔を通過させることができる。このため、加熱空気と吸湿液Ｗとの接触面積を大きくすることができる。よって、吸湿液Ｗの再生を効率的に行うことができる。 Further, in the case of the moisture absorbing chamber 3 having this configuration, the heated air supply unit 9 can allow the heated air to pass through the fine communication holes of the plurality of base materials 5 during the moisture absorbing liquid regeneration step. Therefore, the contact area between the heated air and the hygroscopic liquid W can be increased. Therefore, the hygroscopic liquid W can be efficiently regenerated.
　尚、本実施形態では、複数の基材５が設けられている例について説明したが、本開示の吸湿室はこの構成に限定されない。例えば、基材５は、一つのみ設けられていてもよい。また、吸湿室３に基材５が設けられておらず、吸湿液Ｗのみが配されていてもよい。また、吸湿液供給部３１が複数の基材５に吸湿液Ｗを供給するのであれば、複数の基材５が吸湿液Ｗに接触していなくてもよい。 Although an example in which a plurality of base materials 5 are provided has been described in the present embodiment, the moisture absorption chamber of the present disclosure is not limited to this configuration. For example, only one base material 5 may be provided. Further, the base material 5 may not be provided in the moisture absorbing chamber 3, and only the moisture absorbing liquid W may be arranged. Further, if the hygroscopic liquid supply unit 31 supplies the hygroscopic liquid W to the plurality of base materials 5, the plurality of base materials 5 may not be in contact with the hygroscopic liquid W.
　また、本実施形態では、吸湿室３が、吸湿液供給部３１を有している例について説明した。しかし、本開示の吸湿室３は、この構成に限定されない。基材５に吸湿液Ｗが含浸していれば、吸湿液供給部３１を有していなくてもよい。 Further, in the present embodiment, an example in which the hygroscopic chamber 3 has the hygroscopic liquid supply unit 31 has been described. However, the moisture absorbing chamber 3 of the present disclosure is not limited to this configuration. If the base material 5 is impregnated with the hygroscopic liquid W, it is not necessary to have the hygroscopic liquid supply unit 31.
　さらに、本実施形態では、複数の基材５の下方の一部が、吸湿液槽３０の吸湿液Ｗに浸漬している例について説明したが、複数の基材５の一部が吸湿液Ｗに浸漬していなくてもよい。 Further, in the present embodiment, an example in which a part of the lower part of the plurality of base materials 5 is immersed in the hygroscopic liquid W of the hygroscopic liquid tank 30 has been described, but a part of the plurality of base materials 5 is immersed in the hygroscopic liquid W. It does not have to be immersed in.
　本実施形態では、吸湿室３内に吸湿液Ｗが含浸された基材５が配されている例について説明したが、本開示はこの構成に限定されない。洗浄機１では、例えば、吸湿室３内に、吸湿液Ｗが含浸された吸水性の樹脂が配されていてもよい。吸湿液Ｗが含浸された吸水性の樹脂は、例えば、複数の球状であってもよい。この場合、複数の球状の樹脂を筒状の容器内に充填することにより構成されたカラム管を、吸湿室３内に配し、カラム管内に洗浄室２から取り込んだ空気を通過させる構成であってもよい。 In the present embodiment, an example in which the base material 5 impregnated with the hygroscopic liquid W is arranged in the hygroscopic chamber 3 has been described, but the present disclosure is not limited to this configuration. In the washing machine 1, for example, a water-absorbent resin impregnated with the hygroscopic liquid W may be arranged in the hygroscopic chamber 3. The water-absorbent resin impregnated with the hygroscopic liquid W may be, for example, a plurality of spheres. In this case, a column tube formed by filling a tubular container with a plurality of spherical resins is arranged in a moisture absorbing chamber 3, and the air taken in from the cleaning chamber 2 is passed through the column tube. You may.

　〈吸湿液循環機構６１〉
　吸湿液循環機構６１は、吸湿液循環ポンプ６２を駆動させることにより、吸湿室３と再生槽６０との間で吸湿液Ｗを循環させる。尚、吸湿液循環機構６１は、吸湿室３と再生槽６０との間で、連続的に吸湿液Ｗを循環させるものであってもよいし、断続的に吸湿液Ｗを循環させるものであってもよい。 <Hygroscopic liquid circulation mechanism 61>

May be.
　吸湿液循環機構６１は、第１移送配管６１ａと第２移送配管６１ｂとを有する。 The hygroscopic liquid circulation mechanism 61 has a first transfer pipe 61a and a second transfer pipe 61b.
　第１移送配管６１ａは、吸湿室３と再生槽６０とに接続されている。第１移送配管６１ａは、吸湿液Ｗが吸湿室３から再生槽６０に移送される際に、吸湿液Ｗが通過する配管である。第１移送配管６１ａには、吸湿液循環ポンプ６２が設けられている。吸湿液循環ポンプ６２は、吸湿室３と再生槽６０との間で吸湿液Ｗを循環させる。 The first transfer pipe 61a is connected to the moisture absorption chamber 3 and the regeneration tank 60. The first transfer pipe 61a is a pipe through which the hygroscopic liquid W passes when the hygroscopic liquid W is transferred from the hygroscopic chamber 3 to the regeneration tank 60. The first transfer pipe 61a is provided with a hygroscopic liquid circulation pump 62.

The second transfer pipe 61b is a pipe through which the hygroscopic liquid W passes when the hygroscopic liquid W is returned from the regeneration tank 60 to the hygroscopic chamber 3.
　尚、本実施形態では、第１移送配管６１ａに吸湿液循環ポンプ６２が設けられている例について説明したが、本開示の洗浄機はこの構成に限定されない。吸湿液循環ポンプ６２は、例えば、第２移送配管６１ｂに設けられていてもよい。 In the present embodiment, an example in which the hygroscopic liquid circulation pump 62 is provided in the first transfer pipe 61a has been described, but the washing machine of the present disclosure is not limited to this configuration. The hygroscopic liquid circulation pump 62 may be provided in, for example, the second transfer pipe 61b.

　本実施形態では、第１実施形態と同様に、吸湿液再生工程を、本洗浄工程と並行して行う例について説明する。 In the present embodiment, as in the first embodiment, an example in which the hygroscopic liquid regeneration step is performed in parallel with the main cleaning step will be described.
　〈加熱空気供給部９〉
　本実施の形態の加熱空気供給部９は、第１実施形態の加熱空気供給部９とは異なり、再生槽６０内へ加熱空気を導くためのものである。加熱空気供給部９は、加熱空気供給配管９ａと、加熱空気供給ファン９ｂと、熱交換器９ｃと、第３開閉バルブ９ｄとを備えている。 <Heating air supply unit 9>
Unlike the heated air supply unit 9 of the first embodiment, the heated air supply unit 9 of the present embodiment is for guiding the heated air into the regeneration tank 60. The heated air supply unit 9 includes a heated air supply pipe 9a, a heated air supply fan 9b, a heat exchanger 9c, and a third on-off valve 9d.
　本実施の形態においては、加熱空気供給配管９ａの一方端が、外気に開放されている点においては、実施の形態１と同様であるが、加熱空気供給配管９ａの他方端は、再生槽６０に接続されている点において、第１実施形態と異なる。したがって、加熱空気供給ファン９ｂが駆動されると、外部から加熱空気供給配管９ａ内に取り込まれた空気は、熱交換器９ｃによって加熱され後、加熱空気供給配管９ａによって再生槽６０まで導かれる。 The present embodiment is the same as the first embodiment in that one end of the heated air supply pipe 9a is open to the outside air, but the other end of the heated air supply pipe 9a is the regeneration tank 60. It differs from the first embodiment in that it is connected to. Therefore, when the heated air supply fan 9b is driven, the air taken into the heated air supply pipe 9a from the outside is heated by the heat exchanger 9c and then guided to the regeneration tank 60 by the heated air supply pipe 9a.
　図８は、第２実施形態に係る洗浄機１ａの吸湿液再生工程（本洗浄工程）を説明するための断面模式図である。 FIG. 8 is a schematic cross-sectional view for explaining the hygroscopic liquid regeneration step (main cleaning step) of the washing machine 1a according to the second embodiment.
　（吸湿液再生工程）
　吸湿液再生工程では、まず、吸湿液循環ポンプ６２を駆動させることにより、吸湿室３内の吸湿液Ｗを、第１移送配管６１ａを介して再生槽６０に移送する。次いで、加熱空気供給ファン９ｂを駆動させると共に、加熱空気供給配管９ａに設けられた第３開閉バルブ９ｄを開放する。これにより、加熱空気供給配管９ａを流れる空気は、温水供給配管２５を流れる温水の熱を熱交換器９ｃ経由して受け取った後、加熱空気供給配管９ａから再生槽６０内に流れ込む。そのため、再生槽６０内の吸湿液Ｗは、高温の空気により加熱される。 (Hygroscopic liquid regeneration process)
In the moisture absorption liquid regeneration step, first, the moisture absorption liquid W in the moisture absorption chamber 3 is transferred to the regeneration tank 60 via the first transfer pipe 61a by driving the moisture absorption liquid circulation pump 62. Next, the heated air supply fan 9b is driven, and the third on-off valve 9d provided in the heated air supply pipe 9a is opened. As a result, the air flowing through the heated air supply pipe 9a receives the heat of the hot water flowing through the hot water supply pipe 25 via the heat exchanger 9c, and then flows into the regeneration tank 60 from the heated air supply pipe 9a. Therefore, the hygroscopic liquid W in the regeneration tank 60 is heated by high temperature air.
　再生槽６０には、霧化機構７０が設けられている。具体的には、本実施形態では、霧化機構７０は、吸湿液Ｗに超音波を付与することにより、吸湿液Ｗに含まれる水分を霧化させる機構である。再生槽６０内の吸湿液Ｗには、霧化機構７０によって超音波が照射される。これにより、吸湿液Ｗに含まれる水分の少なくとも一部は霧化される。霧化された水分は、加熱空気供給配管９ａから供給された空気と接触し、空気中に取り込まれる。これにより、吸湿液Ｗに含まれている水分が低減され、吸湿液Ｗが再生される。 The regeneration tank 60 is provided with an atomization mechanism 70. Specifically, in the present embodiment, the atomization mechanism 70 is a mechanism for atomizing the water contained in the hygroscopic liquid W by applying ultrasonic waves to the hygroscopic liquid W. The hygroscopic liquid W in the regeneration tank 60 is irradiated with ultrasonic waves by the atomization mechanism 70. As a result, at least a part of the water contained in the hygroscopic liquid W is atomized. The atomized water comes into contact with the air supplied from the heated air supply pipe 9a and is taken into the air. As a result, the water content contained in the hygroscopic liquid W is reduced, and the hygroscopic liquid W is regenerated.
　本吸湿液再生工程では、水分排出配管６３の第４開閉バルブ６３ａ及び第２空気配管４１ｂの第２開閉バルブ４４が開放される。このため、水分を取り込んだ空気は、水分排出配管６３を通過して、第２空気配管４１ｂに流入する。第２空気配管４１ｂに流入した水分を含んだ空気は、第２開閉バルブが開いているため、洗浄室２内に送り出される。その後、空気中の水分は、洗浄室２において、水滴となって、落下し、洗浄室２の排水口（図示せず）から外部へ排出される。 In this hygroscopic liquid regeneration step, the fourth on-off valve 63a of the moisture discharge pipe 63 and the second on-off valve 44 of the second air pipe 41b are opened. Therefore, the air that has taken in moisture passes through the moisture discharge pipe 63 and flows into the second air pipe 41b. The air containing water that has flowed into the second air pipe 41b is sent out into the cleaning chamber 2 because the second on-off valve is open. After that, the moisture in the air becomes water droplets in the cleaning chamber 2 and falls, and is discharged to the outside from the drain port (not shown) of the cleaning chamber 2.
　水分が低減され、再生された吸湿液Ｗは、吸湿液循環ポンプ６２の駆動により、第２移送配管６１ｂを通過して吸湿室３に返送される。 The moisture-reduced and regenerated moisture-absorbing liquid W is driven by the moisture-absorbing liquid circulation pump 62, passes through the second transfer pipe 61b, and is returned to the moisture-absorbing chamber 3.
　尚、本吸湿液再生工程においては、第１開閉バルブ４３は閉塞されている。このため、洗浄室２内の水分を含む空気は吸湿室３内に侵入しない。 In this hygroscopic liquid regeneration step, the first opening / closing valve 43 is closed. Therefore, the air containing moisture in the washing chamber 2 does not enter the moisture absorbing chamber 3.
　上述のように、本実施形態では、再生槽６０内に送られる空気は、加熱空気である。このため、再生槽６０内の吸湿液Ｗは加熱される。一般的に、吸湿液Ｗ中に含まれる水分を霧化させる際に、吸湿液Ｗの温度が高いと霧化効率が上昇する。このため、洗浄機１ａでは、吸湿液Ｗを効率的に再生することができる。 As described above, in the present embodiment, the air sent into the regeneration tank 60 is heated air. Therefore, the hygroscopic liquid W in the regeneration tank 60 is heated. Generally, when the water contained in the hygroscopic liquid W is atomized, if the temperature of the hygroscopic liquid W is high, the atomization efficiency increases. Therefore, in the washing machine 1a, the hygroscopic liquid W can be efficiently regenerated.
　尚、本実施形態では、吸湿液Ｗの再生に、加熱空気を用いる例について説明した。しかし、本開示の洗浄機はこの構成に限定されない。吸湿液再生工程では、常温の空気を再生槽６０内に取り込んでもよい。 In this embodiment, an example in which heated air is used to regenerate the hygroscopic liquid W has been described. However, the washing machine of the present disclosure is not limited to this configuration. In the hygroscopic liquid regeneration step, air at room temperature may be taken into the regeneration tank 60.
　次に、再生槽６０の構成の一例について詳細に説明する。 Next, an example of the configuration of the regeneration tank 60 will be described in detail.
　図９は、再生部６における、再生槽６０の構成の一例を説明するための断面模式図である。 FIG. 9 is a schematic cross-sectional view for explaining an example of the configuration of the regeneration tank 60 in the regeneration unit 6.
　上述のように、再生部６には、霧化機構７０が設けられている。霧化機構７０は、超音波振動子７１と、制御基板７２とを有する。 As described above, the regeneration unit 6 is provided with an atomization mechanism 70. The atomization mechanism 70 has an ultrasonic vibrator 71 and a control board 72.
　超音波振動子７１は、再生槽６０内の調湿液Ｗに超音波を付与する。超音波振動子７１は、再生槽６０の底壁に設けられている。超音波振動子７１は、制御基板７２に接続されている。制御基板７２は、超音波振動子７１を制御する。 The ultrasonic vibrator 71 applies ultrasonic waves to the humidity control liquid W in the regeneration tank 60. The ultrasonic vibrator 71 is provided on the bottom wall of the regeneration tank 60. The ultrasonic vibrator 71 is connected to the control board 72. The control board 72 controls the ultrasonic vibrator 71.
　超音波振動子７１によって再生槽６０内の吸湿液Ｗに超音波が照射されると、超音波振動によって、吸湿液Ｗの液面に吸湿液Ｗの液柱Ｃが形成される。液柱Ｃが加熱空気供給部９から供給された空気と接触すると、液柱Ｃから霧状の水分が分離され、空気中に取り込まれる。これにより、吸湿液Ｗの水分が低減され、吸湿液Ｗが再生される。水分を取り込んだ空気は、上述のように、水分排出配管６３を通過して、第２空気配管４１ｂに流入する。第２空気配管４１ｂに流入した空気は、洗浄室２内に流れ込む。 When ultrasonic waves are applied to the moisture-absorbing liquid W in the regeneration tank 60 by the ultrasonic vibrator 71, the liquid column C of the moisture-absorbing liquid W is formed on the liquid surface of the moisture-absorbing liquid W by the ultrasonic vibration. When the liquid column C comes into contact with the air supplied from the heated air supply unit 9, the mist-like moisture is separated from the liquid column C and taken into the air. As a result, the water content of the hygroscopic liquid W is reduced, and the hygroscopic liquid W is regenerated. As described above, the air that has taken in moisture passes through the moisture discharge pipe 63 and flows into the second air pipe 41b. The air that has flowed into the second air pipe 41b flows into the cleaning chamber 2.
　（第３実施形態）
　図１０～図１３を用いて、第３実施形態に係る洗浄機について説明する。なお、以下の説明においては、第１実施形態と同様である点に関する説明は、特に必要がなければ繰り返さない。本実施形態の洗浄機は、次の点で、第１実施形態に係る洗浄機と異なる。 (Third Embodiment)

In the following description, the description of the same points as in the first embodiment will not be repeated unless there is a particular need. The washing machine of the present embodiment is different from the washing machine of the first embodiment in the following points.
　図１０は、第３実施形態における洗浄機１ｂの、予備洗浄工程を説明するための断面模式図である。 FIG. 10 is a schematic cross-sectional view for explaining the pre-cleaning process of the washing machine 1b according to the third embodiment.
　第１実施形態では、第１空気配管４１ａに第１開閉バルブ４３が設けられており、第２空気配管４１ｂに第２開閉バルブ４４が設けられている例について説明した。しかし、本開示はこの構成に限定されない。 In the first embodiment, an example in which the first on-off valve 43 is provided in the first air pipe 41a and the second on-off valve 44 is provided in the second air pipe 41b has been described. However, the present disclosure is not limited to this configuration.

　第１実施形態では、乾燥工程において、洗浄室２内の空気と吸湿室３内の空気とを循環させていたが、必ずしも洗浄室２内の空気と吸湿室３内の空気とを循環させなくてもよい。 In the first embodiment, in the drying step, the air in the cleaning chamber 2 and the air in the moisture absorbing chamber 3 are circulated, but the air in the cleaning chamber 2 and the air in the moisture absorbing chamber 3 are not necessarily circulated. You may.
　図１３に示すように、外部の空気を加熱供給配管９ａから取り込み、吸湿室３を通過させ、洗浄機２内にその空気を供給した後に、洗浄室２内の空気を洗浄機１ｂの外部へ排出してもよい。本実施形態では、具体的には、洗浄室２からの空気を、第１空気配管４１ａに設けた第１三方弁４３ａから洗浄機１ｂの外部へ排出する。 As shown in FIG. 13, external air is taken in from the heating supply pipe 9a, passed through the moisture absorbing chamber 3, the air is supplied into the washing machine 2, and then the air in the washing room 2 is sent to the outside of the washing machine 1b. It may be discharged. In the present embodiment, specifically, the air from the cleaning chamber 2 is discharged to the outside of the cleaning machine 1b from the first three-way valve 43a provided in the first air pipe 41a.
　尚、第３実施形態では、上述の第１実施形態と動作の異なる点について説明したが、洗浄機１ｂにおいて、第１実施形態と同様の運転を行い、必要に応じて第３実施形態の動作を適宜行ってもよい。 In the third embodiment, the difference in operation from the first embodiment described above has been described, but the washing machine 1b is operated in the same manner as the first embodiment, and the operation of the third embodiment is performed as necessary. May be performed as appropriate.
　（変形例１）
　第１及び第２実施形態では、第１空気配管４１ａにファン４２が設けられている例について説明した。しかし、本開示の洗浄機はこの構成に限定されない。図１４に示すように、例えば、第２空気配管４１ｂにファン９ｂが設けられていてもよい。 (Modification 1)
In the first and second embodiments, an example in which the fan 42 is provided in the first air pipe 41a has been described. However, the washing machine of the present disclosure is not limited to this configuration. As shown in FIG. 14, for example, the fan 9b may be provided in the second air pipe 41b.
　この場合、吸湿液再生工程において、加熱空気供給配管９ａ内の空気をファン４２によって吸湿室３内に引き込むことができる。従って、加熱空気供給配管９ａに、加熱空気供給ファン９ｂを設ける必要が必ずしもない。 In this case, in the hygroscopic liquid regeneration step, the air in the heated air supply pipe 9a can be drawn into the hygroscopic chamber 3 by the fan 42. Therefore, it is not always necessary to provide the heated air supply fan 9b in the heated air supply pipe 9a.
　（変形例２）
　図１５は、吸湿室３の変形例における構成を説明するための断面模式図である。実施形態１では、吸湿室３内に複数の板状の基材５が設けられている例について説明した。しかし、本開示の吸湿室はこの構成に限定されない。図１５に示すように、吸湿室３内には、例えば、斜行ハニカム８（ニチアス技術時報Ｎｏ．３３８：Ｔ／＃８８０５－ＨＷ）が設けられていてもよい。吸湿室３内に取り込まれた空気は、斜行ハニカム８を通過する。本変形例のように、基材として斜行ハニカムを用いた場合、基材５の表面積を大きくすることができる。したがって、吸湿室３内に取り込まれた空気と接触する吸湿液Ｗをより多くすることができる。したがって、洗浄室２から取り込んだ、水分を含んだ空気を、より効率的に乾燥させることができる。 (Modification 2)
FIG. 15 is a schematic cross-sectional view for explaining a configuration in a modified example of the moisture absorption chamber 3. In the first embodiment, an example in which a plurality of plate-shaped base materials 5 are provided in the moisture absorbing chamber 3 has been described. However, the moisture absorption chamber of the present disclosure is not limited to this configuration. As shown in FIG. 15, for example, a diagonal honeycomb 8 (Nichias Technical Time Signal No. 338: T / # 8805-HW) may be provided in the moisture absorbing chamber 3. The air taken into the moisture absorbing chamber 3 passes through the oblique honeycomb 8. When a diagonal honeycomb is used as the base material as in this modification, the surface area of the base material 5 can be increased. Therefore, the amount of the hygroscopic liquid W that comes into contact with the air taken into the hygroscopic chamber 3 can be increased. Therefore, the air containing water taken in from the washing chamber 2 can be dried more efficiently.
