以下、本発明の実施の形態について図面を参照しながら説明する。 BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described with reference to the drawings.

図１、図２において、１は箱型の本体ケースで、この本体ケース１の側面には、吸込口２が配置され、上部には吹出口３が配置されている。 In FIGS. 1 and 2, reference numeral 1 denotes a box-shaped main body case. A suction port 2 is arranged on a side surface of the main body case 1, and an air outlet 3 is arranged on an upper portion thereof.

本体ケース１内には、圧縮機４と放熱器５と膨張器６と吸熱器７とを順次環状に連結し冷媒を循環する冷凍サイクルを設置し、室内空気を吸込口２から吹出口３に送風する送風手段８を設置している。さらに、空気から水分を吸着する吸湿部９および、空気に水分を放出する放湿部１０を有する除湿ロータ１１を備え、放湿部１０に供給される空気、および放湿部１０を加熱する加熱手段１２を備えている。 Inside the main body case 1, a refrigeration cycle is installed in which a compressor 4, a radiator 5, an expander 6, and a heat absorber 7 are sequentially connected in an annular fashion to circulate the refrigerant. A blowing means 8 for blowing air is installed. Furthermore, a dehumidifying rotor 11 having a moisture absorbing portion 9 that adsorbs moisture from the air and a moisture releasing portion 10 that releases moisture to the air is provided, and the air supplied to the moisture releasing portion 10 and the heating for heating the moisture releasing portion 10 are provided. Means 12 are provided.

そして、本体ケース１内においては、吸込口２から順次、除湿ロータ１１、吸熱器７、放熱器５、送風手段８の順に配置している。除湿ロータ１１は、円板状に形成され中心軸が水平方向になるように回転可能に立設され、駆動手段１３により回転している。さらに除湿ロータ１１の放湿部１０の風上側には、加熱手段１２を設置している。放湿部１０と吸熱器７とは、対向するように配置されている。 In the main body case 1, the dehumidifying rotor 11, the heat absorber 7, the radiator 5, and the air blowing means 8 are arranged in this order from the suction port 2. As shown in FIG. The dehumidification rotor 11 is formed in a disc shape and is rotatably erected so that its center axis is horizontal, and is rotated by the driving means 13 . Further, a heating means 12 is installed on the windward side of the moisture releasing section 10 of the dehumidifying rotor 11 . The moisture releasing part 10 and the heat absorber 7 are arranged to face each other.

また、本体ケース１内において、吸熱器７の下方には、漏斗状の集水手段１４を設け、さらに、集水手段１４の下方には集水タンク１５を、本体ケース１に対して着脱自在に配置している。 In addition, a funnel-shaped water collecting means 14 is provided below the heat absorber 7 in the main body case 1 , and a water collecting tank 15 is provided below the water collecting means 14 so as to be detachable from the main body case 1 . are placed in

さらに、本体ケース１内には、第１送風路１６と、第２送風路１７と、第３送風路１８とを備えている。第１送風路１６は、送風手段８によって、吸込口２から空気を吸引し吸湿部９に供給し、送風手段８を介して吹出口３に排出する風路である。第２送風路１７は、送風手段８によって、吸込口２から空気を吸引し加熱手段１２、放湿部１０、吸熱器７、放熱器５の順に供給し、送風手段８を介して吹出口から排出する風路である。 Furthermore, a first air passage 16 , a second air passage 17 , and a third air passage 18 are provided inside the main body case 1 . The first air passage 16 is an air passage through which air is sucked from the suction port 2 by the air blowing means 8 , supplied to the moisture absorbing portion 9 , and discharged to the air blowing port 3 via the air blowing means 8 . The second air passage 17 sucks air from the suction port 2 by the air blowing means 8, supplies the air to the heating means 12, the moisture desorption part 10, the heat absorber 7, and the radiator 5 in this order, and supplies the air from the air outlet via the blowing means 8. It is an air passage to discharge.

詳細に説明すると、第１送風路１６においては、吸込口２から吸い込まれた室内空気は除湿ロータ１１の吸湿部９に供給される。この時、空気中の水分が吸湿部９に吸着され、乾燥した空気となる。さらに、水分を吸着する際の吸着熱が発生するので、室内空気は湿度が低減し、温度が上昇した状態で、放熱器５および吸熱器７の上方を主に介して送風手段８に吸引され、吹出口３から室内へ送風されることになる。 Specifically, in the first air passage 16 , the indoor air sucked from the suction port 2 is supplied to the moisture absorbing portion 9 of the dehumidifying rotor 11 . At this time, the moisture in the air is absorbed by the moisture absorption part 9 and the air becomes dry. Furthermore, since heat of adsorption is generated when moisture is adsorbed, the indoor air is sucked by the air blowing means 8 mainly above the radiator 5 and the heat absorber 7 in a state where the humidity is reduced and the temperature is increased. , the air is blown into the room from the air outlet 3.

一方、第２送風路１７においては、加熱手段１２によって温められた室内空気は、除湿ロータ１１の放湿部１０に供給される。放湿部１０では、吸湿部９で吸着した水分が除湿ロータ１１の回転駆動により放湿部１０に移動し、加熱手段１２の加熱により供給された空気に放出される。この高湿の空気が吸熱器７に供給され、冷却されることにより結露し、水分は水滴として取出される。この後、冷却された空気は、放熱器５に供給され、放熱器５を冷却する。そして、放熱器５から熱を奪い、温度が上昇した空気が送風手段８に吸引されることになる。冷凍サイクルとしては、放熱器５を効果的に冷却することが、吸熱器７を冷却するに際して、冷却効率を上昇させることになる。 On the other hand, in the second air passage 17 , the room air warmed by the heating means 12 is supplied to the moisture releasing section 10 of the dehumidifying rotor 11 . In the moisture desorption part 10 , the moisture adsorbed by the moisture absorption part 9 is moved to the moisture desorption part 10 by the rotational drive of the dehumidification rotor 11 and released into the supplied air by heating by the heating means 12 . This high-humidity air is supplied to the heat absorber 7 and cooled to condense, and the moisture is taken out as water droplets. After that, the cooled air is supplied to the radiator 5 to cool the radiator 5 . Then, the air whose temperature has risen by taking heat from the radiator 5 is sucked into the air blowing means 8 . As for the refrigerating cycle, effective cooling of the radiator 5 increases the cooling efficiency when cooling the heat absorber 7 .

また、第３送風路１８においては、吸込口２から空気を吸引し吸熱器７、放熱器５の順に供給し、送風手段８を介して吹出口３から排出する。すなわち、第３送風路１８においては、吸込口２から吸い込まれた室内空気が吸熱器７に供給され、冷却されることにより結露し、水分は水滴として取り出される。この後、冷却された空気は、放熱器５に供給され、放熱器５を冷却する。そして放熱器５から熱を奪い、温度が上昇した空気が送風手段８に吸引されることになる。 In the third air passage 18 , air is sucked from the suction port 2 , supplied to the heat absorber 7 and the radiator 5 in this order, and discharged from the air outlet 3 via the air blowing means 8 . That is, in the third air passage 18, the indoor air sucked from the suction port 2 is supplied to the heat absorber 7 and cooled to condense, and water is taken out as water droplets. After that, the cooled air is supplied to the radiator 5 to cool the radiator 5 . Then, the air whose temperature rises by taking heat from the radiator 5 is sucked into the air blowing means 8 .

図３において、内部構成をさらに詳しく説明すると、本体ケース１内には、除湿ロータ１１を回動自在に支持するロータ支持部１９を設ける。ロータ支持部１９には、加熱手段１２、駆動手段１３も備えている。 Referring to FIG. 3, the internal structure will be described in more detail. Inside the main body case 1, a rotor support portion 19 that supports the dehumidification rotor 11 so as to be rotatable is provided. The rotor support 19 is also provided with heating means 12 and driving means 13 .

本実施形態において特徴的なのは、第３送風路の風量を調整する、風量調整手段２０を設けたことである。風量調整手段２０によって、第３送風路１８の風量をコントロールすることで、吸熱器７に最適な風量を送ることが可能となり、結果として、除湿性能の向上を図ることができる。例えば、室内雰囲気温度が低いときは、風量調整手段２０によって、第３送風路１８の風量を減らすことにより、第２送風路１７の風量を増加させるとともに、吸熱器７に通過する風量を減らす効果がある。すなわち、室内の冷えた空気は吸熱器７には供給されにくくなり、第２送風路１７の、加熱手段１２によって室温度よりも温められた空気が吸熱器７に供給されやすくなる。一般的な冷凍サイクルにおいて、周囲温度が低温になると、吸熱器７の除湿水が氷結し、吸熱器７に霜として付着することで除湿能力が著しく低下する。そこで、吸熱器７に付着した霜を取り除くために、定期的に冷凍サイクルの運転を停止し、除霜運転を実施する。吸熱器７に霜が付着した状態では除湿性能が低下することに加えて、除霜運転中は除湿性能が得られない。風量調整手段２０によって、第３送風路１８の風量を減らすことにより、吸熱器７に室温よりも温かい空気が供給され、吸熱器７の霜付を防ぐ効果が期待できる。結果として、除湿性能の向上を図ることができる。 A feature of this embodiment is that an air volume adjustment means 20 is provided for adjusting the air volume of the third air passage. By controlling the air volume of the third air passage 18 with the air volume adjusting means 20, it is possible to send the optimum air volume to the heat absorber 7, and as a result, it is possible to improve the dehumidification performance. For example, when the indoor ambient temperature is low, the air volume adjustment means 20 reduces the air volume of the third air passage 18, thereby increasing the air volume of the second air passage 17 and reducing the air volume passing through the heat absorber 7. There is That is, cold air in the room is less likely to be supplied to the heat absorber 7 , and air warmed above the room temperature by the heating means 12 in the second air duct 17 is more likely to be supplied to the heat absorber 7 . In a general refrigeration cycle, when the ambient temperature becomes low, the dehumidified water in the heat absorber 7 freezes and adheres to the heat absorber 7 as frost, resulting in a significant reduction in dehumidification performance. Therefore, in order to remove the frost adhering to the heat absorber 7, the operation of the refrigerating cycle is periodically stopped and the defrosting operation is performed. When the heat absorber 7 is covered with frost, the dehumidifying performance is lowered and the dehumidifying performance cannot be obtained during the defrosting operation. By reducing the air volume of the third air passage 18 by the air volume adjustment means 20, air warmer than room temperature is supplied to the heat absorber 7, and the effect of preventing the heat absorber 7 from frosting can be expected. As a result, it is possible to improve the dehumidification performance.

また、図３、図４に示すごとく、風量調整手段２０は、第３送風路１８の吸込口２と吸熱器７との間に設ける。第２送風路１７の空気と、第３送風路１８の空気は、吸熱器７以降、徐々に混合しながら吹出口３へと向かうため、吸熱器７の上流に設けることで、最も効率的に第３送風路１８を閉塞することができる。結果として、除湿性能の向上を図ることができる。 Further, as shown in FIGS. 3 and 4 , the air volume adjusting means 20 is provided between the suction port 2 of the third air passage 18 and the heat absorber 7 . After the heat absorber 7, the air in the second air passage 17 and the air in the third air passage 18 are gradually mixed and headed toward the outlet 3. The third air passage 18 can be closed. As a result, it is possible to improve the dehumidification performance.

また、風量調整手段２０は、加熱手段１２または除湿ロータ１１の下方に配置する。加熱手段１２または除湿ロータ１１の下方の空間に風量調整手段２０を配置するので、本体ケース１を大きくする必要がない。 Also, the air volume adjusting means 20 is arranged below the heating means 12 or the dehumidifying rotor 11 . Since the air volume adjusting means 20 is arranged in the space below the heating means 12 or the dehumidifying rotor 11, the main body case 1 does not need to be enlarged.

更に、第２送風路１７では、放湿部１０直後の室温より高い温度の空気を、吸熱器７における冷媒が流れている方向の下流側（吸熱器７の上部）の冷媒温度が比較的高い領域に通過させる。一方、第３送風路１８では、室内の空気を、第３送風路１８から吸熱器７における冷媒が流れている方向の上流側（吸熱器７の下部）の冷媒温度が比較的低い領域に通過させることができる。結果として、吸熱器７を効率的に利用することで、除湿性能の向上を図ることができる。 Furthermore, in the second air passage 17, the air having a temperature higher than the room temperature immediately after the moisture desorption section 10 is blown to the downstream side of the heat absorber 7 in the direction in which the refrigerant flows (the upper part of the heat absorber 7), where the refrigerant temperature is relatively high. pass through the area. On the other hand, in the third air passage 18, the indoor air passes from the third air passage 18 to a region where the refrigerant temperature is relatively low on the upstream side (lower portion of the heat absorber 7) in the direction in which the refrigerant flows in the heat absorber 7. can be made As a result, by efficiently using the heat absorber 7, the dehumidification performance can be improved.

図３は、風量調整手段２０が開いた状態である。図３を用いて、ロータ支持部１９の構成について、さらに詳しく説明すると、ロータ支持部１９は、除湿ロータ１１を回動自在に支持し、ロータ支持部１９には、第３送風路１８が通る連通開口２０ｂを有している。風量調整手段２０は、第３送風路１８が通る連通開口２０ｂと、この連通開口２０ｂを開閉する風量調整部材２０ａである。このように、ロータ支持部１９に、連通開口２０ｂと風量調整部材２０ａとを設けることにより、風量調整手段２０を支持する新たな支持部材を設ける必要が無く、部品点数を低減できる。 FIG. 3 shows a state in which the air volume adjusting means 20 is open. The configuration of the rotor support portion 19 will be described in more detail with reference to FIG. It has a communication opening 20b. The air volume adjusting means 20 includes a communicating opening 20b through which the third air passage 18 passes, and an air volume adjusting member 20a for opening and closing the communicating opening 20b. Thus, by providing the communication opening 20b and the air volume adjusting member 20a in the rotor supporting portion 19, there is no need to provide a new supporting member for supporting the air volume adjusting means 20, and the number of parts can be reduced.

図４は、風量調整手段２０が閉じた状態である。風量調整部材２０ａについて、さらに詳しく説明すると、図４と図５に示すように、風量調整部材２０ａは、水平方向に開口した連通開口２０ｂを塞ぐダンパ部２２と、ダンパ部２２から水平外方に延びた一対の軸部２３と、軸部２３を支持するロータ支持部１９に設けた支持部２４と、軸部２３を介してダンパ部２２を回動させるモータ部（図示せず）とを備え、ダンパ部２２は、連通開口２０ｂから吸込口２側に回動する、つまり送風方向における下流側から上流側に開く構成とする。すなわち、ダンパ部２２を閉じたとき、送風手段８によって、より閉塞される方向に力が働き、冷凍サイクルや送風手段８等、回転物特有のビビリ音の発生を防ぐ効果が得られる。 FIG. 4 shows a state in which the air volume adjusting means 20 is closed. 4 and 5, the air volume adjustment member 20a includes a damper portion 22 that closes a communication opening 20b that opens in the horizontal direction, and a damper portion 22 that extends horizontally outward from the damper portion 22. A pair of extended shafts 23 , a support 24 provided on the rotor support 19 that supports the shafts 23 , and a motor (not shown) that rotates the damper 22 via the shafts 23 . , The damper portion 22 is configured to rotate from the communication opening 20b toward the suction port 2 side, that is, open from the downstream side to the upstream side in the blowing direction. That is, when the damper portion 22 is closed, the air blowing means 8 exerts a force in the direction of closing the air blowing means 8, thereby obtaining an effect of preventing chattering noise peculiar to rotating objects such as the refrigerating cycle and the air blowing means 8.

また、ダンパ部２２は、連通開口２０ｂの開口面積よりも大きくする構成とするとよい。これにより、吸込み側にロータ支持部１９と重なる面を持たせることができる。結果として、閉塞レベルを向上することが可能である。 Also, the damper portion 22 may be configured to have a larger opening area than the communication opening 20b. As a result, the suction side can have a surface that overlaps with the rotor support portion 19 . As a result, it is possible to improve the occlusion level.

風量調整部材２０ａの下方には集水手段１４を設ける構成とするとよい。先述の通り、集水手段１４は吸熱器７の下方に配置するが、本実施形態では、風量調整部材２０ａの下方にも延長する構成とする。低温などの雰囲気で運転し、連通開口２０ｂを閉じて運転する場合に、ロータ支持部１９と吸熱器７に囲まれた空間が高温多湿状態に保たれ、風量調整部材２０ａの吸熱器７方向に結露が発生する可能性がある。風量調整部材２０ａに結露が発生した場合でも、を外部に漏らすことなく、集水タンク１５に回収することができ、結果として、ユーザーの使用性を向上できる。 A water collection means 14 may be provided below the air volume adjusting member 20a. As described above, the water collecting means 14 is arranged below the heat absorber 7, but in this embodiment, it is configured to extend below the air volume adjusting member 20a. When operating in an atmosphere such as a low temperature and operating with the communication opening 20b closed, the space surrounded by the rotor support portion 19 and the heat absorber 7 is kept in a hot and humid state, and the air volume adjustment member 20a moves toward the heat absorber 7. Condensation may occur. Even if condensation occurs on the air volume adjusting member 20a, it can be collected in the water collection tank 15 without leaking to the outside, and as a result, usability for the user can be improved.

更に、軸部２３とダンパ部２２の構成について詳しく説明すると、軸部２３をダンパ部２２の下端側に設け、ダンパ部２２の上端側が、吸込口２側、つまり送風方向における上流側に開口する構成とするとよい。すなわち、ダンパ部２２が開状態（通常の運転状態）では、ダンパ部２２が、風量調整部材２０ａの下方に配置された集水手段１４に当たり、支持される構成になり、モータ部に負荷がかからないため、結果として、モータ部の故障リスクを軽減することができる。 Further, the structure of the shaft portion 23 and the damper portion 22 will be described in detail. configuration. That is, when the damper portion 22 is in the open state (normal operating state), the damper portion 22 hits the water collecting means 14 arranged below the air volume adjusting member 20a and is supported, so that no load is applied to the motor portion. Therefore, as a result, the risk of failure of the motor section can be reduced.

風量調整部材２０ａの動作方法について、詳細に説明する。図３と図６に示すように、本体ケース１内には、第１の温度測定部２５と、第２の温度測定部２７と、湿度測定部２８と、制御部２６とを備えている。制御部２６は、第１の温度測定部２５、第２の温度測定部２７、湿度測定部２８との測定値によって、冷凍サイクルの圧縮機４と、送風手段８と、除湿ロータ１１を回転させる駆動手段１３と、加熱手段１２と、風量調整部材２０ａとを制御する。 A method of operating the air volume adjusting member 20a will be described in detail. As shown in FIGS. 3 and 6, the body case 1 includes a first temperature measurement section 25, a second temperature measurement section 27, a humidity measurement section 28, and a control section . The control unit 26 rotates the compressor 4 of the refrigeration cycle, the air blowing means 8, and the dehumidification rotor 11 based on the measured values of the first temperature measurement unit 25, the second temperature measurement unit 27, and the humidity measurement unit 28. It controls the driving means 13, the heating means 12, and the air volume adjusting member 20a.

具体的には、第１の温度測定部２５は、吸込口２の近傍に設けてられている。制御部２６は、除湿運転中に、第１の温度測定部２５の測定温度によって風量調整部材２０ａを制御する。制御部２６は、第１の温度測定部２５の測定温度が第１の所定温度以下の場合には、圧縮機４と、送風手段８と、駆動手段１３と、加熱手段１２とを動作させ、風量調整部材２０ａによって第３送風路１８を閉じる構成とするのがよい。すなわち、第３送風路１８を閉じることによって、吸熱器７に加熱手段１２を通過した温かい空気が供給され、かつ、冷えた室温空気の供給を抑制することにより、吸熱器７の霜付を防ぐことができる。除湿性能の向上を図ることができる。なお、第１の所定温度の一例は、１０度から２０度である。 Specifically, the first temperature measurement unit 25 is provided near the suction port 2 . The control unit 26 controls the air volume adjustment member 20a according to the temperature measured by the first temperature measurement unit 25 during the dehumidification operation. When the temperature measured by the first temperature measuring unit 25 is equal to or lower than the first predetermined temperature, the control unit 26 operates the compressor 4, the air blowing means 8, the driving means 13, and the heating means 12, It is preferable to employ a configuration in which the third air passage 18 is closed by the air volume adjusting member 20a. That is, by closing the third air passage 18, warm air that has passed through the heating means 12 is supplied to the heat absorber 7, and by suppressing the supply of cold room temperature air, the heat absorber 7 is prevented from frosting. be able to. It is possible to improve dehumidification performance. An example of the first predetermined temperature is 10 degrees to 20 degrees.

第２の温度測定部２７は、吸熱器７に設けられている。制御部２６は、除湿運転中に、第２の温度測定部２７の測定温度によって風量調整部材２０ａおよび圧縮機４を制御する。制御部２６は、第２の温度測定部２７の測定温度が第２の所定温度以下の場合には、送風手段８と、駆動手段１３と、加熱手段１２とを動作させ、風量調整部材２０ａによって第３送風路１８を閉じ、かつ、圧縮機４を停止する構成とするのがよい。なお、第２の所定温度の一例は、０度から４度である。 A second temperature measurement unit 27 is provided in the heat absorber 7 . The control unit 26 controls the air volume adjustment member 20a and the compressor 4 according to the temperature measured by the second temperature measurement unit 27 during the dehumidification operation. When the temperature measured by the second temperature measuring unit 27 is equal to or lower than the second predetermined temperature, the control unit 26 operates the air blowing unit 8, the driving unit 13, and the heating unit 12, and the air volume adjusting member 20a It is preferable that the third air passage 18 is closed and the compressor 4 is stopped. An example of the second predetermined temperature is 0 degrees to 4 degrees.

先述の通り、吸熱器７には、一定の温度以下で霜が付着するため、先述のように、第１の温度測定部２５の温度が所定温度以下の場合には、風量調整部材２０ａによって、第３送風路１８を閉じる構成とするのがよい。しかしながら、第３送風路を閉じた状態、または、第１の温度測定部２５の温度が第１の所定温度以上のときであっても、湿度や風量などの条件により、霜が発生する場合があり、着霜の検知には、第２の温度測定部２７のように吸熱器７に温度測定部を設ける構成とするのがよい。すなわち、第２の温度測定部２７の検知温度が第２の所定温度以下の場合には、制御部２６は、風量調整部材２０ａによって第３送風路１８を閉じ、かつ、圧縮機４を停止し、除霜モードに自動的に切り替わるものとするのがよい。すなわち、第３送風路１８を閉じることによって、吸熱器７に加熱手段１２を通過した温かい空気が供給され、結果として、除霜性能の向上を図ることができる。 As described above, frost adheres to the heat absorber 7 at a certain temperature or lower. A configuration in which the third air passage 18 is closed is preferable. However, even when the third air passage is closed, or when the temperature of the first temperature measuring unit 25 is equal to or higher than the first predetermined temperature, frost may occur depending on conditions such as humidity and air volume. Therefore, it is preferable to provide a temperature measuring section in the heat absorber 7 like the second temperature measuring section 27 for detecting frost formation. That is, when the temperature detected by the second temperature measuring unit 27 is equal to or lower than the second predetermined temperature, the control unit 26 closes the third air passage 18 by the air volume adjusting member 20a and stops the compressor 4. , it should automatically switch to the defrosting mode. That is, by closing the third air passage 18, warm air that has passed through the heating means 12 is supplied to the heat absorber 7, and as a result, defrosting performance can be improved.

湿度測定部２８は、第１の温度測定部２５の近傍に設けられている。制御部２６は、除湿運転中に、湿度測定部２８の測定湿度によって風量調整部材２０ａを制御する。制御部２６は、湿度測定部２８の湿度が所定の湿度以下の場合には、圧縮機４と、送風手段８と、駆動手段１３と、加熱手段１２とを動作させ、風量調整部材２０ａによって第３送風路１８を閉じる構成とするのがよい。なお、第２の所定湿度の一例は、３０％から５０％である。 The humidity measuring section 28 is provided near the first temperature measuring section 25 . The control unit 26 controls the air volume adjustment member 20a according to the humidity measured by the humidity measurement unit 28 during the dehumidification operation. When the humidity measured by the humidity measuring unit 28 is equal to or lower than the predetermined humidity, the control unit 26 operates the compressor 4, the air blowing means 8, the driving means 13, and the heating means 12, and the air volume adjusting member 20a controls the second humidity. 3 It is preferable that the blowing path 18 is closed. An example of the second predetermined humidity is 30% to 50%.

高湿条件では、加熱手段１２で温められた空気が、放湿部１０を通過し、除湿ロータ１１に吸着している水分を脱着するときに温度が低下する。低湿条件では、除湿ロータ１１の吸湿部９に供給される水分量が少なくなる。すなわち、除湿ロータ１１の放湿部１０で放湿される水分量が少なくなり、第２送風路１７における放湿部１０の下流が過熱される恐れがある。湿度測定部２８の湿度が所定湿度以下の場合に、風量調整部材２０ａによって第３送風路１８を閉じることにより、除湿ロータ１１の風量が増加する。つまり、吸放湿量が増加し、放湿部１０下流の温度上昇が少なくなる。さらに、第２送風路の風量も増加するため、加熱手段１２の放熱が促進され、放湿部１０下流の温度上昇を抑える方向に働く。結果として、放湿部１０周辺の樹脂の過昇温を防ぐことができ、安全性の向上が期待できる。 Under high-humidity conditions, the air warmed by the heating means 12 passes through the moisture releasing section 10 and the temperature drops when the moisture adsorbed on the dehumidifying rotor 11 is desorbed. Under low humidity conditions, the amount of moisture supplied to the moisture absorbing portion 9 of the dehumidifying rotor 11 is reduced. That is, the amount of moisture released by the moisture release section 10 of the dehumidification rotor 11 is reduced, and there is a risk that the downstream side of the moisture release section 10 in the second air passage 17 will be overheated. When the humidity measured by the humidity measuring unit 28 is equal to or lower than the predetermined humidity, the air volume of the dehumidifying rotor 11 is increased by closing the third air passage 18 with the air volume adjusting member 20a. That is, the amount of moisture absorption and desorption increases, and the temperature rise downstream of the moisture desorption section 10 decreases. Furthermore, since the air volume of the second air passage also increases, the heat dissipation of the heating means 12 is promoted, and it works in the direction of suppressing the temperature rise downstream of the moisture releasing section 10 . As a result, it is possible to prevent excessive temperature rise of the resin around the moisture release section 10, and an improvement in safety can be expected.

図２と図３に示すように、本体ケース１内には、第４送風路２９を備えている。第４送風路２９は、送風手段８によって、吸込口２から空気を吸引し放熱器５に供給し、送風手段８を介して吹出口３に排出する風路である。制御部２６は、第１の温度測定部２５が第３の所定温度以上の場合は、圧縮機４と、送風手段８と、駆動手段１３と、加熱手段１２とを動作させ、風量調整部材２０ａによって第３送風路１８を閉じる構成とするのがよい。なお、第３の所定温度は第１の所定温度より高く、第３の所定温度の一例は、３０度から４０度である。 As shown in FIGS. 2 and 3, the body case 1 is provided with a fourth air passage 29 . The fourth air passage 29 is an air passage through which air is sucked from the suction port 2 by the air blowing means 8 , supplied to the radiator 5 , and discharged to the air outlet 3 via the air blowing means 8 . When the temperature of the first temperature measuring unit 25 is equal to or higher than the third predetermined temperature, the control unit 26 operates the compressor 4, the air blowing unit 8, the driving unit 13, and the heating unit 12, and controls the air volume adjusting member 20a. It is preferable to have a configuration in which the third air passage 18 is closed by . The third predetermined temperature is higher than the first predetermined temperature, and an example of the third predetermined temperature is 30 degrees to 40 degrees.

第４送風路２９は、放熱器５の放熱を促進するために設けるもので、特に高温条件では、吸熱器７の吸熱量が増加し、放熱器５の放熱量とのバランスが崩れ、放熱器５の内圧が上昇し、圧縮機４が過熱する恐れがある。すなわち、第３送風路１８を閉じることにより、相対的に放熱器５の風量を増加させることができ、結果として、圧縮機４の寿命を長くする効果が期待できる。 The fourth air passage 29 is provided to promote heat dissipation from the radiator 5. Especially under high temperature conditions, the amount of heat absorbed by the heat absorber 7 increases, and the balance with the amount of heat released from the radiator 5 is lost. There is a risk that the internal pressure of 5 will rise and the compressor 4 will overheat. That is, by closing the third air passage 18, the air volume of the radiator 5 can be relatively increased, and as a result, the effect of lengthening the life of the compressor 4 can be expected.
