　特許文献１には、除湿すべき空気を本体内へ吸入し、かつこの空気を顕熱交換器の一方の通路を経て、回転自在な吸湿ロータへ送り、吸湿ロータで除湿された空気を本体外へ排出する第１ファンと、ヒータにより加熱された空気を上記除湿ロータへ送って吸湿ロータの水分を蒸発させることにより吸湿ロータを再生し、かつ高湿となった空気を上記顕熱交換器の他方の通路へ送って顕熱交換器内で結露を発生させた後、再びヒータを経て吸湿ロータへ循環させる第２ファンと、上記顕熱交換器内に結露した結露水を回収する手段とを具備したことを特徴とする除湿装置が開示されている。 In Patent Document 1, air to be dehumidified is sucked into the main body, and this air is sent to a rotatable hygroscopic rotor through one passage of the sensible heat exchanger, and the air dehumidified by the hygroscopic rotor is removed from the main body. The first fan discharged to the heater and the air heated by the heater are sent to the dehumidifying rotor to evaporate the moisture in the hygroscopic rotor, thereby regenerating the hygroscopic rotor, and the humid air is removed from the sensible heat exchanger. A second fan that is sent to the other passage to cause condensation in the sensible heat exchanger, and then circulates again through the heater to the moisture-absorbing rotor, and means for recovering the condensed water in the sensible heat exchanger. There is disclosed a dehumidifying device characterized by comprising.
　この除湿装置では、吸入された室内の空気は、顕熱交換器、吸湿ロータを経て、外部に排出される。また、除湿装置内の循環空気は、ヒータ、吸湿ロータ、顕熱交換器というサイクルで流れる。 In this dehumidifier, the inhaled indoor air is discharged to the outside through a sensible heat exchanger and a moisture absorption rotor. The circulating air in the dehumidifier flows in a cycle of a heater, a moisture absorption rotor, and a sensible heat exchanger.
特許２８１９４９７号Japanese Patent No. 2819497
　しかし、特許文献１に開示されている除湿装置は、熱交換の効率化を改善する余地がある。熱交換が効率よくなされないと、除湿対象の空気の除湿効率も限定的になる。顕熱交換器は、除湿対象の空気の流路でみれば、吸湿ロータに対して前に位置し、顕熱交換器と吸湿ロータとの間の距離がほとんどないため、顕熱交換器の冷却効率が悪く、結果として除水量が少なかった。 However, the dehumidifying device disclosed in Patent Document 1 has room for improving the efficiency of heat exchange. If heat exchange is not performed efficiently, the dehumidification efficiency of the air to be dehumidified is limited. The sensible heat exchanger is located in front of the hygroscopic rotor in the air flow path to be dehumidified, and there is almost no distance between the sensible heat exchanger and the hygroscopic rotor. The efficiency was poor, and as a result, the amount of water removed was small.
　そこで、本発明は、熱交換の効率化を改善して、除湿対象の空気の除湿効率を高めることを課題とする。 Therefore, an object of the present invention is to improve the efficiency of heat exchange and increase the dehumidification efficiency of the air to be dehumidified.
　上記課題を解決するために、本発明の除湿装置は、除湿対象の空気を吸入して当該空気に含まれる水分を吸い取る手段と、前記水分を含む相対的に高温である空気に対して前記除湿対象の空気の吸入ルートとは異なるルートから吸入された相対的に低温である空気を用いて熱交換を行う手段とを備える。 In order to solve the above-described problems, the dehumidifying apparatus of the present invention includes a unit that sucks in air to be dehumidified and absorbs moisture contained in the air, and the dehumidifying device with respect to air that contains the moisture and is at a relatively high temperature. And means for performing heat exchange using relatively cool air sucked from a route different from the target air suction route.
　具体的には、この除湿装置は、一例ではあるが、前記除湿対象の空気を吸入する第１ファンと、前記相対的に低温である空気を吸入する第２ファンとを備えている。もっとも、この除湿装置は、さらに、前記相対的に高温である空気を、前記熱交換を行う手段に対して送る第３ファンを備えている。この場合、各ファンは、一つのモータによって回転すれば、除湿装置の省スペース化を維持できる。さらには、前記相対的に低温である空気の流路を規定する規定部を有すると、熱交換の効率化が一層向上される。 Specifically, this dehumidifying device includes, as an example, a first fan that sucks in air to be dehumidified and a second fan that sucks in air that is relatively low in temperature. However, the dehumidifier further includes a third fan that sends the relatively hot air to the means for performing heat exchange. In this case, if each fan is rotated by one motor, the space saving of the dehumidifier can be maintained. Furthermore, the efficiency of heat exchange is further improved by having a defining part that defines the flow path of the air having a relatively low temperature.

　以下、説明の都合上、図５を参照しつつ、各部材について順次説明する。 Hereinafter, for convenience of explanation, each member will be sequentially described with reference to FIG.
　ロータケース１３は、除湿対象の空気吸入上流に設けられている。ロータケース１３は、ロータケース１６とともに、吸湿ロータ１４を収容するケースである。ロータケース１３には、吸湿ロータ１４の除湿対象の空気の吸入位置に対応した開口部が形成されている。具体的には、この開口部は、吸湿ロータ１４の面積の例えば２／３程度の大きさの扇形としている。また、ロータケース１３は、開口部の円弧の両端間から円弧の外に向けて延びる隆起部分が形成されている。この隆起部分は、ＰＴＣヒータ１５によって加温されてから吸湿ロータ１４を通過する、除湿装置内の循環空気を、熱交換器ケース２１に送る部分となる。 The rotor case 13 is provided upstream of air intake to be dehumidified. The rotor case 13 is a case that houses the hygroscopic rotor 14 together with the rotor case 16. The rotor case 13 is formed with an opening corresponding to the intake position of the air to be dehumidified by the moisture absorption rotor 14. Specifically, the opening has a fan shape having a size of about 2/3 of the area of the hygroscopic rotor 14, for example. Further, the rotor case 13 is formed with a raised portion extending from both ends of the arc of the opening portion toward the outside of the arc. This raised portion serves as a portion for sending the circulating air in the dehumidifying device, which passes through the hygroscopic rotor 14 after being heated by the PTC heater 15, to the heat exchanger case 21.
　ロータケースカバー１２は、上記隆起部分に対して一体的に形成されていて、ロータケースカバー１２の平面方向に対する直交部分に、螺子止め等により取り付けられている。 The rotor case cover 12 is integrally formed with the raised portion, and is attached to a portion orthogonal to the planar direction of the rotor case cover 12 by screwing or the like.
　ロータモータ１は、吸湿ロータ１４を回転させるためのモータである。ロータモータ１は、本実施形態では、ロータケース１３の下部に設置されているが、ロータモータ１の設置場所はこれに限定されるものではない。なお、ロータモータ１を用いることなく、吸湿ロータ１４によって吸い取られた水分の重さを利用して、吸湿ロータ１４を回転させることも可能である。 The rotor motor 1 is a motor for rotating the hygroscopic rotor 14. In this embodiment, the rotor motor 1 is installed in the lower part of the rotor case 13, but the installation location of the rotor motor 1 is not limited to this. In addition, it is also possible to rotate the moisture absorption rotor 14 using the weight of the water sucked by the moisture absorption rotor 14 without using the rotor motor 1.
　ロータホイール２は、ロータホイール３とともに、吸湿ロータ１４を収容するホイールである。ロータホイール２は、吸湿ロータ１４に対応する大きさで、例えば６つのスポークを有する輪状である。ロータホイール２の周縁部分には、歯が刻まれていて、ロータモータ１に接続されている歯車と噛み合うように構成されている。したがって、ロータモータ１を駆動することによって、吸湿ロータ１４が回転することになる。 The rotor wheel 2 is a wheel that houses the hygroscopic rotor 14 together with the rotor wheel 3. The rotor wheel 2 has a size corresponding to the hygroscopic rotor 14 and has a ring shape having, for example, six spokes. The peripheral portion of the rotor wheel 2 is engraved with teeth and is configured to mesh with a gear connected to the rotor motor 1. Therefore, by driving the rotor motor 1, the moisture absorption rotor 14 is rotated.
　ロータホイール３は、ロータホイール２と同様に、例えば６つのスポークを有する輪状のものである。ロータホイール２，３は、吸湿ロータ１４を挟みこみ、除湿装置内における吸湿ロータ１４の位置決めを行っている。ロータホイール３の周縁部分には、ロータホイール２と結合するための例えば４つの結合部が設けられている。 As with the rotor wheel 2, the rotor wheel 3 is, for example, a ring-shaped member having six spokes. The rotor wheels 2 and 3 sandwich the hygroscopic rotor 14 and position the hygroscopic rotor 14 in the dehumidifier. For example, four coupling portions for coupling with the rotor wheel 2 are provided at the peripheral portion of the rotor wheel 3.
　吸湿ロータ１４は、上記のように、ロータホイール２，３によって位置決めがなされ、ロータホイール２，３と共に、中心軸周りに回転自在とされている。吸湿ロータ１４は、ロータケース１３の開口部を通じて吸入される除湿対象の空気を受け、この空気に含まれている湿気を吸い取るものである。吸湿ロータ１４は、炭酸カルシウム、塩化カルシウム、塩化リチウム、シリカゲル、水酸化アルミニウム、モレキューラシーブス、タルク、ゾノトライト、ケイ酸化マグネシウム、パルプ等の湿気を吸収或いは吸着する物質を含浸又はコーティングしたものとしている。 The moisture absorbing rotor 14 is positioned by the rotor wheels 2 and 3 as described above, and is rotatable around the central axis together with the rotor wheels 2 and 3. The moisture absorption rotor 14 receives the air to be dehumidified sucked through the opening of the rotor case 13 and absorbs moisture contained in the air. The moisture absorption rotor 14 is impregnated or coated with a substance that absorbs or adsorbs moisture such as calcium carbonate, calcium chloride, lithium chloride, silica gel, aluminum hydroxide, molecular sieves, talc, zonotrite, magnesium silicate, and pulp. Yes.
　ロータケース１６は、ロータケース１３の開口部に対応する箇所に、開口部が形成されている。また、ロータケース１６は、ロータケース１３における既述の隆起部分に対応する箇所には、除湿装置内を循環する循環空気の通路が形成されている。 The rotor case 16 has an opening formed at a location corresponding to the opening of the rotor case 13. Further, the rotor case 16 is formed with a passage of circulating air that circulates in the dehumidifier at a position corresponding to the above-described raised portion of the rotor case 13.
　ＰＴＣヒータ１５は、ロータケース１６に形成されている循環空気の通路内に装着される。ＰＴＣヒータ１５は、温度制御機能を有するヒータである。ＰＴＣヒータ１５の基本原理は、温度の上昇により抵抗が増加して発熱を停止し、温度の下降により抵抗が減少して発熱を再開するものである。なお、ＰＴＣヒータ１５を設けることは必須ではない。ＰＴＣヒータ１５を設ける意図は、熱交換器用パイプ２２での熱交換を実現することであるので、例えば、熱交換器用パイプ２２へ送る冷却用の空気を、冷却装置を用いて冷却することで、除湿を行うことも可能である。 The PTC heater 15 is mounted in a circulating air passage formed in the rotor case 16. The PTC heater 15 is a heater having a temperature control function. The basic principle of the PTC heater 15 is to stop the heat generation by increasing the resistance due to a rise in temperature, and to restart the heat generation by decreasing the resistance due to a decrease in temperature. It is not essential to provide the PTC heater 15. Since the intent of providing the PTC heater 15 is to realize heat exchange in the heat exchanger pipe 22, for example, by cooling the cooling air sent to the heat exchanger pipe 22 using a cooling device, It is also possible to perform dehumidification.
　ＰＴＣヒータカバー４は、ロータケース１６の循環空気の通路内に装着されるＰＴＣヒータ１５を、ロータケース１６に固定するものである。 The PTC heater cover 4 fixes the PTC heater 15 mounted in the circulating air passage of the rotor case 16 to the rotor case 16.
　通気ダクト１７は、上記循環空気を、ＰＴＣヒータ１５に向けて通すダクトである。通気ダクト１７は、ロータケース１６の上記通路の開口部に取り付けられる。通気ダクト１７を通る循環空気は、ＰＴＣヒータ１５によって加熱される。 The ventilation duct 17 is a duct for passing the circulating air toward the PTC heater 15. The ventilation duct 17 is attached to the opening of the passage of the rotor case 16. The circulating air passing through the ventilation duct 17 is heated by the PTC heater 15.
　ファンケース５は、前ファン６のケースである。ファンケース５は、前ファン６に対応する大きさの開口部が形成されている。なお、除湿された空気は、ファンケース５と前ファン６との隙間を通り、図示しない排出口を経由して、除湿装置外に排出される。 The fan case 5 is a case of the front fan 6. The fan case 5 has an opening having a size corresponding to the front fan 6. The dehumidified air passes through the gap between the fan case 5 and the front fan 6 and is discharged out of the dehumidifying device via a discharge port (not shown).
　前ファン６は、除湿対象の空気を除湿装置内に吸入するためのものである。本実施形態の除湿装置は、前ファン６と中ファン８と後ファン２５という、３つのファンを備えているが、前ファン６の直径が最も小さい。各ファン６，８，２５の径を異ならせているのは、本実施形態では、ＡＣモータ１１という一つのモータを用いて、合計３つの各ファン６，８，２５を回転させていることが一要因である。この点については、後述する。 The front fan 6 is for sucking the air to be dehumidified into the dehumidifier. The dehumidifying device of this embodiment includes three fans, that is, the front fan 6, the middle fan 8, and the rear fan 25, but the diameter of the front fan 6 is the smallest. The reason why the diameters of the fans 6, 8, and 25 are different from each other is that, in this embodiment, a total of three fans 6, 8, and 25 are rotated using a single motor called the AC motor 11. One factor. This point will be described later.
　ファン固定プレート１８は、前ファン６を、ＡＣモータ１１に連結するためのプレートである。具体的には、ファン固定プレート１８は、中央部分に孔が設けられていて、この孔内に対して、ＡＣモータ１１に接続されているシャフトが通された状態で、前ファン６とＡＣモータ１１との連結がなされる。 The fan fixing plate 18 is a plate for connecting the front fan 6 to the AC motor 11. Specifically, the fan fixing plate 18 is provided with a hole in the central portion, and the front fan 6 and the AC motor are in a state where a shaft connected to the AC motor 11 is passed through the hole. 11 is connected.
　中ファン８は、熱交換器用パイプ２２を冷却するために、除湿装置の外部から冷却用の空気を吸入するものである。中ファン８は、前ファン６及び後ファン２５に比して、最も直径が大きいし、ファンの幅（図４の左右方向の長さ）もある。中ファン８は、図３に示すように、その中心軸が、熱交換器用パイプ２２の各パイプの軸方向と直交する態様で、熱交換器用パイプ２２に隣接設置されている。このため、冷却用の空気を、熱交換器用パイプ２２のパイプ間に、効率よく通過させることが可能となる。なお、中ファン８の直径を、前ファン６の直径よりも大きくする理由は、除湿対象の空気の吸入及び排出量よりも、熱交換器用パイプ２２の冷却用の空気の吸入及び排出量が多く必要であるためである。こうして、本実施形態では、熱交換効率を向上させている。 The middle fan 8 sucks cooling air from the outside of the dehumidifier to cool the heat exchanger pipe 22. The middle fan 8 has the largest diameter compared to the front fan 6 and the rear fan 25, and also has a fan width (length in the left-right direction in FIG. 4). As shown in FIG. 3, the middle fan 8 is disposed adjacent to the heat exchanger pipe 22 such that the central axis thereof is orthogonal to the axial direction of each pipe of the heat exchanger pipe 22. For this reason, it becomes possible to efficiently pass the cooling air between the pipes of the heat exchanger pipe 22. The reason why the diameter of the middle fan 8 is made larger than the diameter of the front fan 6 is that the amount of air sucked and discharged for cooling the heat exchanger pipe 22 is larger than the amount of air sucked and discharged as the object of dehumidification. This is because it is necessary. Thus, in this embodiment, the heat exchange efficiency is improved.
　ファン固定プレート７は、中ファン８を、ＡＣモータ１１に連結するためのプレートである。具体的には、ファン固定プレート７は、中央部分に孔が設けられていて、この孔内に対して、ＡＣモータ１１に接続されているシャフトが通された状態で、中ファン８とＡＣモータ１１との連結がなされる。 The fan fixing plate 7 is a plate for connecting the middle fan 8 to the AC motor 11. Specifically, the fan fixing plate 7 is provided with a hole in the central portion, and the medium fan 8 and the AC motor are in a state where a shaft connected to the AC motor 11 is passed through the hole. 11 is connected.
　ファンケース１９は、前ファン６と中ファン８との双方を収容するケースである。ファンケース１９は、前ファン６の収容部と中ファン８の収容部とが仕切られていて、除湿対象の空気と熱交換器用パイプ２２の冷却用の空気とが混在しないようにしてある。また、ファンケース１９は、図３に示すように、熱交換器用パイプ２２を冷却する冷却用の空気が、熱交換器用パイプ２２に対して効率よく当たるように、風向きを規定する規定部１９Ａが端部に設けられている。 The fan case 19 is a case that accommodates both the front fan 6 and the middle fan 8. In the fan case 19, the housing portion of the front fan 6 and the housing portion of the middle fan 8 are partitioned so that the air to be dehumidified and the air for cooling the heat exchanger pipe 22 are not mixed. Further, as shown in FIG. 3, the fan case 19 has a defining portion 19 </ b> A that regulates the wind direction so that the cooling air for cooling the heat exchanger pipe 22 efficiently hits the heat exchanger pipe 22. It is provided at the end.
　熱交換器ケース２１は、熱交換器用パイプ２２の上方に設けられていて、吸湿ロータ１４を通過することによって高温多湿となった循環空気を、熱交換器用パイプ２２に送るものである。 The heat exchanger case 21 is provided above the heat exchanger pipe 22, and sends the circulating air that has become hot and humid by passing through the hygroscopic rotor 14 to the heat exchanger pipe 22.
　上部熱交換器ホルダ２０は、熱交換器用パイプ２２の上部側と連結されるものである。具体的には、上部熱交換器ホルダ２０には、熱交換器用パイプ２２の各パイプに連結される複数の孔が設けられている。熱交換器ケース２１を通じて送られてきた循環空気は、これらの孔を通じて、熱交換器用パイプ２２に送られる。上部熱交換器ホルダ２０は、規定部１９Ａと同様の趣旨で設けられていて、熱交換器用パイプ２２に対して、冷却用の空気を効率よく当てるためのものである。 The upper heat exchanger holder 20 is connected to the upper side of the heat exchanger pipe 22. Specifically, the upper heat exchanger holder 20 is provided with a plurality of holes connected to each pipe of the heat exchanger pipe 22. The circulating air sent through the heat exchanger case 21 is sent to the heat exchanger pipe 22 through these holes. The upper heat exchanger holder 20 is provided for the same purpose as the defining portion 19 </ b> A, and is for efficiently applying cooling air to the heat exchanger pipe 22.
　熱交換器用パイプ２２は、高温多湿の循環空気の熱エネルギーを、中ファン８を回転させることによって除湿装置内に取り込んだ低温の冷却用の空気に伝えるものである。循環空気は、熱交換器用パイプ２２を通る際に冷却され、その一部は各パイプ内で結露することになる。 The heat exchanger pipe 22 transmits the heat energy of the hot and humid circulating air to the low-temperature cooling air taken into the dehumidifier by rotating the middle fan 8. The circulating air is cooled when passing through the heat exchanger pipe 22, and a part of the circulating air is condensed in each pipe.
　下部熱交換器ホルダ１０は、熱交換器用パイプ２２の下部側と連結されるものである。具体的には、下部熱交換器ホルダ１０には、熱交換器用パイプ２２の各パイプに連結される複数の孔が設けられている。熱交換器２６によって冷却された循環空気は、排出ダクト９に送られる。下部熱交換器ホルダ１０は、規定部１９Ａと同様の趣旨で設けられていて、熱交換器用パイプ２２に対して、冷却用の空気を効率よく当てるためのものである。 The lower heat exchanger holder 10 is connected to the lower side of the heat exchanger pipe 22. Specifically, the lower heat exchanger holder 10 is provided with a plurality of holes connected to each pipe of the heat exchanger pipe 22. The circulating air cooled by the heat exchanger 26 is sent to the discharge duct 9. The lower heat exchanger holder 10 is provided for the same purpose as the defining portion 19A, and is for efficiently applying cooling air to the heat exchanger pipe 22.
　排出ダクト９は、下部熱交換器ホルダ１０を経由した循環空気を後ファン２５に向けて排出すると共に、熱交換器用パイプ２２のパイプ内の結露水を、図示しない容器に排出するものである。 The discharge duct 9 discharges the circulating air passing through the lower heat exchanger holder 10 toward the rear fan 25 and discharges condensed water in the pipe of the heat exchanger pipe 22 to a container (not shown).
　ＡＣモータ１１は、前ファン６と中ファン８と後ファン２５との各々を回転させるものである。もっとも、前ファン６と中ファン８と後ファン２５とを、一つのＡＣモータによって回転させるのではなく、複数のＡＣモータによって回転させてもよい。 The AC motor 11 rotates each of the front fan 6, the middle fan 8, and the rear fan 25. However, the front fan 6, the middle fan 8, and the rear fan 25 may be rotated by a plurality of AC motors instead of being rotated by a single AC motor.
　モータケース２３は、ＡＣモータ１１を収容するケースである。具体的には、モータケース２３は、ＡＣモータ１１に対応する大きさの窪部、及び、ＡＣモータ１１に接続されるシャフトを通す開口部が形成されている。この窪部部内に、ＡＣモータ１１が収容され、螺子止めなどによって、モータケース２３に固定される。また、モータケース２３は、図３に示すように、熱交換器用パイプ２２を冷却する冷却用の空気が、熱交換器用パイプ２２に対して効率よく当たるように、風向きを規定する規定部２３Ａが端部に設けられている。なお、モータケース２３のうち、ＡＣモータ１１の外周を覆う部分などに、熱交換器用パイプ２２を冷却するための外気を通す開口部を設けてもよい。 The motor case 23 is a case that accommodates the AC motor 11. Specifically, the motor case 23 has a recess having a size corresponding to the AC motor 11 and an opening through which a shaft connected to the AC motor 11 passes. The AC motor 11 is accommodated in the recess and is fixed to the motor case 23 by screwing or the like. Further, as shown in FIG. 3, the motor case 23 has a regulating portion 23 </ b> A that regulates the wind direction so that the cooling air for cooling the heat exchanger pipe 22 efficiently hits the heat exchanger pipe 22. It is provided at the end. In addition, you may provide the opening part which lets the external air for cooling the pipe 22 for heat exchangers in the part etc. which cover the outer periphery of the AC motor 11 among the motor cases 23. FIG.
　ファンケース２４は、後ファン２５を収容するケースである。ファンケース２４には、モータケース２３の窪部を受ける開口部が形成されている。また、ファンケース２４の上部には、通気ダクト１７と連結され、後ファン２５側から送られてくる循環空気を通気１７に送る開口部が形成されている。 The fan case 24 is a case that houses the rear fan 25. The fan case 24 is formed with an opening for receiving the recess of the motor case 23. Further, an opening is formed in the upper part of the fan case 24 so as to be connected to the ventilation duct 17 and send the circulating air sent from the rear fan 25 side to the ventilation 17.
　後ファン２５は、除湿装置内の循環空気の当該循環を実現するファンである。後ファン２５は、後ファン２５は、前ファン６より直径が大きいが、中ファン８ほどではない。なお、各ファン６，８，２５の直径は、例えば１５８ｍｍ、２０８ｍｍ、１８８ｍｍとしている。この場合、各ファン６，８，２５の直径比率は１：１．３７：１．１９となるが、一例として、１：１．２～１．４：１．１～１．３の範囲から適宜決定すればよい。また、各ファン６，８，２５の幅は３０ｍｍ、３４ｍｍ、２３ｍｍとしている。この場合、各ファン６，８，２５の幅比率は１：１．１３：０．７７となるが、一例として、１：１．１～１．３：０．７～０．９の範囲から適宜決定すればよい。 The rear fan 25 is a fan that realizes the circulation of the circulating air in the dehumidifier. The rear fan 25 is larger in diameter than the front fan 6 but not as large as the middle fan 8. In addition, the diameter of each fan 6,8,25 is 158 mm, 208 mm, and 188 mm, for example. In this case, the diameter ratio of the fans 6, 8, and 25 is 1: 1.37: 1.19. As an example, the diameter ratio is from 1: 1.2 to 1.4: 1.1 to 1.3. What is necessary is just to determine suitably. The widths of the fans 6, 8, 25 are 30 mm, 34 mm, and 23 mm. In this case, the width ratio of the fans 6, 8, 25 is 1: 1.13: 0.77. As an example, the width ratio is from 1: 1.1 to 1.3: 0.7 to 0.9. What is necessary is just to determine suitably.
　ファン固定プレート２７は、後ファン２５を、ＡＣモータ１１に連結するためのプレートである。具体的には、ファン固定プレート２７は、中央部分に孔が設けられていて、この孔内に対して、ＡＣモータ１１に接続されているシャフトが通された状態で、後ファン２５とＡＣモータ１１との連結がなされる。 The fan fixing plate 27 is a plate for connecting the rear fan 25 to the AC motor 11. Specifically, the fan fixing plate 27 is provided with a hole in the central portion, and the rear fan 25 and the AC motor are connected to the hole with a shaft connected to the AC motor 11 passing therethrough. 11 is connected.
　ファンケースカバー２６は、後ファン２５を挟み込む態様で、ファンケース２４に螺子止め等によって取り付けられるカバーである。 The fan case cover 26 is a cover that is attached to the fan case 24 by screwing or the like in such a manner as to sandwich the rear fan 25.
　つぎに、図１に示す除湿装置の動作時の空気の流れについて説明する。まずは、除湿対象の空気に関して説明する。 Next, the flow of air during the operation of the dehumidifier shown in FIG. 1 will be described. First, the air to be dehumidified will be described.
　除湿装置の電源がオンされると、ロータモータ１及びＡＣモータ１１が駆動する。これに伴って、吸湿ロータ１４が回転を開始し、かつ、各ファン６，８，２５が回転を開始する。また、ＰＴＣヒータ１５が通電することで、発熱を開始する。 When the power of the dehumidifier is turned on, the rotor motor 1 and the AC motor 11 are driven. Along with this, the hygroscopic rotor 14 starts rotating, and the fans 6, 8, 25 start rotating. Further, when the PTC heater 15 is energized, heat generation is started.
　前ファン６が回転すると、除湿装置内の空気を排気しようとすることになるので、除湿装置周辺の空気、すなわち、除湿対象の空気が、除湿装置内に吸入されることになる。具体的には、ロータケース１３の開口部を通じて、除湿対象の空気が、除湿装置内に吸入される。 When the front fan 6 rotates, the air in the dehumidifier is exhausted, so the air around the dehumidifier, that is, the air to be dehumidified, is sucked into the dehumidifier. Specifically, the air to be dehumidified is sucked into the dehumidifier through the opening of the rotor case 13.
　つづいて、除湿対象の空気は、ロータホイール２のスポーク間を介して、吸湿ロータ１４に到達する。この結果、除湿対象の空気中の湿気が、吸湿ロータ１４によって吸い取られる。吸湿ロータ１４は、既述のように、ロータモータ１の駆動により回転されるので、吸湿ロータ１４の湿気吸取部分は、ＰＴＣヒータ１５に向けて移動される。 Subsequently, the air to be dehumidified reaches the hygroscopic rotor 14 through the spokes of the rotor wheel 2. As a result, moisture in the air to be dehumidified is absorbed by the moisture absorption rotor 14. Since the moisture absorption rotor 14 is rotated by driving the rotor motor 1 as described above, the moisture absorption portion of the moisture absorption rotor 14 is moved toward the PTC heater 15.
　一方、吸湿ロータ１４を通過することによって除湿処理がなされた空気は、ロータホイール３のスポーク間を介して、ロータケース１６を通り、前ファン６に到達する。除湿処理がなされた空気は、前ファン６の回転により、除湿装置の外部へ排気される。以上のような工程によって、除湿対象の空気は、除湿される。 On the other hand, the air that has been dehumidified by passing through the hygroscopic rotor 14 passes through the rotor case 16 through the spokes of the rotor wheel 3 and reaches the front fan 6. The dehumidified air is exhausted to the outside of the dehumidifier by the rotation of the front fan 6. The air to be dehumidified is dehumidified by the process described above.
　また、ＡＣモータ１１の駆動により、後ファン２５が回転されるので、除湿装置内の循環空気の循環が実現される。さらに、ＰＴＣヒータ１５が通電されることで、循環空気が加熱される。吸湿ロータ１４には、ＰＴＣヒータ１５によって加熱された高温低湿の循環空気が通される。吸湿ロータ１４によって吸い取られた湿気は、高温低湿の循環空気と接触することによって乾燥されるので、吸湿ロータ１４から湿気が除去される。これにより、吸湿ロータ１４は、除湿対象の空気の湿気が吸収可能となる。 In addition, since the rear fan 25 is rotated by driving the AC motor 11, circulation of the circulating air in the dehumidifier is realized. Furthermore, circulating air is heated by energizing the PTC heater 15. High-temperature, low-humidity circulating air heated by the PTC heater 15 is passed through the moisture absorption rotor 14. The moisture sucked out by the moisture absorption rotor 14 is dried by contact with the high-temperature and low-humidity circulating air, so that the moisture is removed from the moisture absorption rotor 14. Thereby, the moisture absorption rotor 14 can absorb the moisture of the air to be dehumidified.
　一方、吸湿ロータ１４を通過した循環空気は、高温多湿状態となり、ロータケース１３の隆起部分、ロータケースカバー１２を介して、熱交換器ケース２１に到達する。さらに、当該循環空気は、上部熱交換器ホルダ２０の孔を通じて、熱交換器用パイプ２２に進む。 On the other hand, the circulating air that has passed through the hygroscopic rotor 14 is in a hot and humid state, and reaches the heat exchanger case 21 through the raised portion of the rotor case 13 and the rotor case cover 12. Further, the circulating air proceeds to the heat exchanger pipe 22 through the hole of the upper heat exchanger holder 20.
　ＡＣモータ１１の駆動により、中ファン８が回転され、しかも、下部熱交換器ホルダ１０、上部熱交換器ホルダ２０、規定部１９Ａ、規定部２３Ａによって囲まれる部分に対応する位置に、熱交換器用パイプ２２が設けられているので、熱交換器用パイプ２２のパイプ間に、効率よく相対的に多量の空気が流れることになる。この空気は、熱交換器用パイプ２２内を通る循環空気よりも相対的に低温であるので、結果的には、循環空気を冷却することになる。なお、規定部１９Ａ等を設けたのは、熱交換器用パイプ２２のパイプ間は空気抵抗が相対的に高いので、仮に、規定部１９Ａ等を設けなかった場合には、パイプ間を避けて通る空気量が増加して、熱交換器用パイプ２２の冷却効率が低下するためである。 By driving the AC motor 11, the middle fan 8 is rotated, and at the position corresponding to the portion surrounded by the lower heat exchanger holder 10, the upper heat exchanger holder 20, the defining portion 19 </ b> A, and the defining portion 23 </ b> A, Since the pipe 22 is provided, a relatively large amount of air efficiently flows between the pipes of the heat exchanger pipe 22. This air is relatively cooler than the circulating air passing through the heat exchanger pipe 22, and as a result, the circulating air is cooled. The provision of the defining portion 19A and the like is because the air resistance between the pipes of the heat exchanger pipe 22 is relatively high. Therefore, if the defining portion 19A and the like are not provided, the passage between the pipes is avoided. This is because the amount of air increases and the cooling efficiency of the heat exchanger pipe 22 decreases.
　なお、この冷却用の空気は、除湿対象の空気とは異なるルートで、除湿装置の外部から吸入され、熱交換器用パイプ２２のパイプ間を経由して、除湿対象の空気とは異なる　　ルートで、除湿装置の外部へ排気される。 The cooling air is different from the air to be dehumidified and is sucked from the outside of the dehumidifying device, passes through the pipes of the heat exchanger pipe 22, and is different from the air to be dehumidified. It is exhausted outside the dehumidifier.
　循環空気は、熱交換器用パイプ２２内で冷却されることで熱交換される。循環空気は、熱交換によって一部が液化されるので、熱交換器用パイプ２２の内壁には結露が発生する。結露は、所定量を超えると、自重により、当該内壁をつたって、下部熱交換器ホルダ１０の孔、及び、排出ダクト９を通って容器に到達する。 The circulating air is heat-exchanged by being cooled in the heat exchanger pipe 22. Since part of the circulating air is liquefied by heat exchange, dew condensation occurs on the inner wall of the heat exchanger pipe 22. When the dew condensation exceeds a predetermined amount, the dew reaches the container through its inner wall through the hole of the lower heat exchanger holder 10 and the discharge duct 9 due to its own weight.
　また、熱交換器用パイプ２２内で冷却された循環空気は、下部熱交換器ホルダ１０の孔、及び、排出ダクト９を通って、後ファン２５に到達する。そして、循環空気は、後ファン２５の回転により、通気ダクト１７に送られる。通気ダクト１７には、ＰＴＣヒータ１５が設けられているので、循環空気は、既述のように、過熱されて、高温低湿状態となる。 Also, the circulating air cooled in the heat exchanger pipe 22 reaches the rear fan 25 through the hole of the lower heat exchanger holder 10 and the discharge duct 9. The circulating air is sent to the ventilation duct 17 by the rotation of the rear fan 25. Since the PTC heater 15 is provided in the ventilation duct 17, the circulating air is overheated as described above to be in a high temperature and low humidity state.
　図６は、本発明の実施例の除湿装置の分解斜視図であり、図５に対応するものである。図６に示す除湿装置は、図５のものと同様であるが、以下の点を変更している。なお、これらの変更点は、全てを採用することが必須ではなく、図５に示した除湿装置に対して選択的に採用してもよい。 FIG. 6 is an exploded perspective view of the dehumidifier according to the embodiment of the present invention, and corresponds to FIG. The dehumidifying device shown in FIG. 6 is the same as that of FIG. 5, but the following points are changed. In addition, it is not essential to employ all of these changes, and they may be selectively employed for the dehumidifying apparatus shown in FIG.
　ファンケース５及びファンケース１９は、その上部に、前ファン６を回転させることによって、処理後の空気を排出する際の流路を規定する規定部を設けている。これにより、処理後の空気と熱交換器用パイプ２２へ送る冷却用空気とが混在することを抑止している。 The fan case 5 and the fan case 19 are provided with a defining portion that defines a flow path for discharging the processed air by rotating the front fan 6 at the upper part thereof. Thereby, mixing of the air after a process and the cooling air sent to the pipe 22 for heat exchangers is suppressed.
　ロータケースカバー１２は、幅寸法（処理対象の空気の流れに直交する方向：図面の奥行き方向）を狭めるため、形状を変更している。具体的には、幅寸法を狭めるとともに、厚み処理対象の空気の流れる方向）を増加させるような形状としている。 The shape of the rotor case cover 12 is changed in order to narrow the width dimension (direction perpendicular to the air flow to be processed: the depth direction in the drawing). Specifically, the shape is such that the width dimension is narrowed and the thickness of the air to be processed is increased.
　ＰＴＣヒータカバー４、ＰＴＣヒータ１５との位置ずれがなくなるように、例えば、３本のリブを追加している。 For example, three ribs are added so that the positional deviation between the PTC heater cover 4 and the PTC heater 15 is eliminated.
　熱交換器ケース２１は、その上斜部に、電源プリント基板ボードアッセンブリを装着するためのネジボスを設けている。なお、電源プリント基板ボードアッセンブリの装着箇所は、熱交換器ケース２１に限定されず、装置の筺体内のデッドスペースをなくせるような箇所とすればよい。 The heat exchanger case 21 is provided with a screw boss for mounting the power printed board board assembly on the upper oblique portion. Note that the place where the power printed circuit board board assembly is mounted is not limited to the heat exchanger case 21 and may be a place where the dead space in the housing of the apparatus can be eliminated.
　冷却用ファン８Ａは、ＡＣモータ１１との連結をやめ、別途、冷却用８Ａ駆動用のモータを内蔵等し、中ファン８に対して回転軸を直交させている。この結果、冷却用ファン８Ａの径は中ファン８の径よりも小さくなるので省スペース化が図れ、冷却用ファン８Ａの向きを流路に対応させることで効果的に熱交換器用パイプ２２を冷却するようにしている。 The cooling fan 8A is disconnected from the AC motor 11 and has a separate built-in motor for driving the cooling 8A, and the rotational axis thereof is orthogonal to the middle fan 8. As a result, the diameter of the cooling fan 8A is smaller than the diameter of the middle fan 8, so that space can be saved, and the heat exchanger pipe 22 is effectively cooled by making the direction of the cooling fan 8A correspond to the flow path. Like to do.
