Description

本発明は、居住空間などに用いられる除湿装置に関するものである。   The present invention relates to a dehumidifying device used in a living space or the like.

居住空間の湿度を低下させ、快適性を増すものとして除湿装置が実用化されている。   Dehumidifiers have been put into practical use as a means of reducing the humidity of living spaces and increasing comfort.

その構成としては、吸込口と吹出口を有する本体ケース内に、圧縮機と放熱器と膨張器と吸熱器とを順次環状に連結した冷凍サイクルと、吸湿部で水分を吸着し放湿部で水分を放出する除湿ロータと、放湿部に供給される空気を加熱する加熱手段と、空気を送風する送風手段を備えたものとなっている。   The structure includes a refrigeration cycle in which a compressor, a radiator, an expander, and a heat absorber are sequentially connected in a ring in a main body case having a suction port and a blower outlet, and moisture is adsorbed by the moisture absorption unit. A dehumidification rotor that releases moisture, a heating unit that heats air supplied to the moisture release unit, and a blowing unit that blows air are provided.

そして、吸込口から空気を吸引し放熱器に供給して吹出口から排出する第１送風路と、吸込口から空気を吸引し吸熱器に供給して吹出口から排出する第２送風路を備え、第１送風路の放熱器に供給される空気の少なくとも一部が除湿ロータの吸湿部を通り、第２送風路の吸熱器に供給される空気の少なくとも一部が除湿ロータの放湿部を通るような構成となっている（例えば下記特許文献１）。   And a first air passage that sucks air from the suction port, supplies the heat to the radiator, and discharges it from the air outlet; and a second air passage that sucks air from the air inlet, supplies the heat to the heat absorber, and discharges it from the air outlet. At least part of the air supplied to the radiator of the first air passage passes through the moisture absorption part of the dehumidification rotor, and at least part of the air supplied to the heat absorber of the second air passage passes through the moisture release part of the dehumidification rotor. It is the composition which passes (for example, the following patent documents 1).

特許第４５９１２４３号公報Japanese Patent No. 4591233

上記従来例では、放熱器には室内空気をそのまま供給する、もしくは、除湿ロータの吸湿部を通過した空気を供給する構成となっている。   In the conventional example, indoor air is supplied to the radiator as it is, or air that has passed through the moisture absorbing portion of the dehumidifying rotor is supplied.

一方、吸湿部を通過した空気は、除湿ロータが吸湿した際の吸着熱や、放湿部での加熱手段での加熱の余熱などにより、温度が上昇することになる。   On the other hand, the temperature of the air that has passed through the hygroscopic part rises due to the heat of adsorption when the dehumidifying rotor absorbs moisture, the residual heat of heating by the heating means in the moisture releasing part, and the like.

つまり、冷凍サイクルの放熱器を冷却するのに、室温の空気もしくは、室温からさらに温度が上昇した空気を利用することになる。この場合、放熱器と冷却空気との温度差を大きくとることは難しく、冷凍サイクルの効率が低下し、引いては除湿効率の低下を招く結果となっていた。もし、除湿効率を維持しようとした場合には、必要熱量を冷却するために、放熱器に供給する空気量を増加させる必要があり、送風手段の大型化という課題があった。   In other words, room temperature air or air whose temperature has further increased from room temperature is used to cool the radiator of the refrigeration cycle. In this case, it is difficult to increase the temperature difference between the radiator and the cooling air, and the efficiency of the refrigeration cycle is reduced, which in turn leads to a decrease in dehumidification efficiency. If an attempt is made to maintain the dehumidification efficiency, it is necessary to increase the amount of air supplied to the radiator in order to cool the necessary heat amount, and there is a problem of increasing the size of the blowing means.

そこで、本発明は、本体サイズをコンパクトにしながら、除湿効率を高めることを目的とするものである。   Accordingly, the object of the present invention is to increase the dehumidification efficiency while reducing the size of the main body.

そして、この目的を達成するために、本発明は、吸込口と吹出口を有する本体ケース内に、圧縮機、放熱器、膨張器、吸熱器を順次環状に連結し冷媒を循環する冷凍サイクルと、吸湿部および放湿部を有する除湿ロータと、加熱手段と、を備え、前記吸込口から空気を記吸湿部に供給して前記吹出口から排出する第１送風路と、前記吸込口から空気を吸引し前記加熱手段、前記放湿部、前記吸熱器、前記放熱器の順に供給して前記吹出口から排出する第２送風路と、を備えた構成とし、これにより所期の目的を達成するものである。   And in order to achieve this object, the present invention includes a refrigeration cycle in which a compressor, a radiator, an expander, and a heat absorber are sequentially connected in an annular manner in a main body case having an inlet and an outlet, and a refrigerant is circulated. A dehumidification rotor having a moisture absorption part and a moisture release part, and a heating means, a first air passage for supplying air from the suction port to the moisture absorption part and exhausting from the blower outlet, and air from the suction port And a second air passage that supplies the heating means, the moisture release section, the heat absorber, and the heat radiator in this order and discharges them from the air outlet, thereby achieving the intended purpose. To do.

以上のように本発明は、吸込口から空気を吸引し吸湿部に供給して吹出口から排出する第１送風路と、吸込口から空気を吸引し放湿部、吸熱器、放熱器の順に供給して吹出口から排出する第２送風路とを備えた構成としたので、冷凍サイクルの放熱器には、吸熱器により室温より低い温度に冷却された空気を供給し、除湿ロータの吸湿部を通過した温度の上昇した空気の送風路とは別の送風路とすることにより、放熱器をより低い温度の空気で冷却することができ、冷凍サイクルの冷却効率を向上させ、除湿装置の除湿効率を向上させることができる。さらに、低温の空気で放熱器を冷却できるので、必要熱量を冷却するのに少ない量の空気で可能となり、風量を低減することが可能となるので、送風手段の小型化が可能となる。この結果、本体サイズをコンパクトにしながら、除湿効率を高めることができるのである。   As described above, the present invention sucks air from the suction port, supplies it to the moisture absorption part and discharges it from the outlet, and sucks air from the suction port in order of the moisture release part, the heat absorber, and the radiator. Since it was made into the structure provided with the 2nd ventilation path which supplies and discharges from a blower outlet, the air cooled to temperature lower than room temperature with a heat absorber is supplied to the heat radiator of a refrigerating cycle, and the moisture absorption part of a dehumidification rotor By using a different air flow path from the air flow path that has passed through the air, the radiator can be cooled with lower temperature air, improving the cooling efficiency of the refrigeration cycle and dehumidifying the dehumidifier Efficiency can be improved. Furthermore, since the radiator can be cooled with low-temperature air, a small amount of air can be used to cool down the required amount of heat, and the amount of air can be reduced, so that the size of the air blowing means can be reduced. As a result, the dehumidifying efficiency can be increased while reducing the size of the main body.

以下、本発明の実施例について図面を参照しながら説明する。   Embodiments of the present invention will be described below with reference to the drawings.

（実施の形態１）
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。 (Embodiment 1)
1 and 2, reference numeral 1 denotes a box-shaped main body case. A suction port 2 is disposed on a side surface of the main body case 1, and an air outlet 3 is disposed on an upper portion.

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。   In the main body case 1, a refrigeration cycle in which a compressor 4, a radiator 5, an expander 6, and a heat absorber 7 are sequentially connected in an annular manner to circulate the refrigerant is installed, and indoor air is passed from the inlet 2 to the outlet 3. Blowing means 8 for blowing air is installed. Furthermore, the dehumidification rotor 11 which has the moisture absorption part 9 which adsorb | sucks a water | moisture content from air, and the moisture release part 10 which discharge | releases a water | moisture content to air is provided, the air supplied to the moisture release part 10, and the heating which heats the moisture release part 10 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。吸熱器７と放熱器５の上端は、同じ高さになるように配置されている。除湿ロータ１１は、円板状に形成され中心軸が水平方向にあ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 heat radiator 5, and the air blowing means 8 are sequentially arranged from the suction port 2. The upper ends of the heat absorber 7 and the radiator 5 are arranged so as to have the same height. The dehumidifying rotor 11 is formed in a disc shape, is erected so as to be rotatable so that the central axis is in the horizontal direction, 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 release part 10 and the heat absorber 7 are arrange | positioned so that it may oppose.

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 the main body case 1, a funnel-shaped water collecting means 14 is provided below the heat absorber 7, and a water collecting tank 15 is detachably attached to the main body case 1 below the water collecting means 14. Is arranged.

つまり、吸熱器７部分で結露をさせ、その結露水を漏斗状の集水手段１４で集めて集水タンク１５に流入させるようにしているのである。   That is, dew condensation is caused at the heat absorber 7, and the condensed water is collected by the funnel-shaped water collecting means 14 and flows into the water collecting tank 15.

本実施形態において特徴的なのは、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に排出する第１送風路１６と、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第２送風路１７を備えたことである。   What is characteristic in the present embodiment is that air is sucked from the suction port 2, supplied to the moisture absorption unit 9, and discharged to the blower outlet 3 through the blower 8, and air is sucked from the suction port 2. The heating means 12, the moisture release unit 10, the heat absorber 7, and the heat radiator 5 are supplied in this order, and the second air passage 17 that discharges from the outlet through the air blowing means 8 is provided.

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。   More 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, moisture in the air is adsorbed by the hygroscopic section 9 and becomes dry air. Furthermore, since heat of adsorption is generated when moisture is adsorbed, the indoor air is sucked into the blowing means 8 mainly through the radiator 5 and the heat absorber 7 with the humidity reduced and the temperature 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 unit 10 of the dehumidifying rotor 11. In the moisture releasing part 10, the moisture adsorbed by the moisture absorbing part 9 moves to the moisture releasing part 10 by the rotational drive of the dehumidifying rotor 11 and is released to the air supplied by the heating of the heating means 12. This high-humidity air is supplied to the heat absorber 7 and is condensed by being cooled, and moisture is taken out as water droplets. Thereafter, the cooled air is supplied to the radiator 5 to cool the radiator 5. And the heat which took heat from the heat radiator 5 and the temperature rose is attracted | sucked by the ventilation means 8. FIG. As the refrigeration cycle, effectively cooling the radiator 5 increases the cooling efficiency when the heat absorber 7 is cooled.

上述のように、冷凍サイクルの放熱器５には、吸熱器７により室温より低い温度に冷却された空気を供給し、除湿ロータ１１の吸湿部９を通過した温度の上昇した空気の送風路とは別の送風路とすることにより、放熱器５をより低い温度の空気で冷却することができ、冷凍サイクルの冷却効率を向上させ、除湿装置の除湿効率を向上させることができる。さらに、低温の空気で放熱器を冷却できるので、必要熱量を冷却するのに少ない量の空気で可能となり、風量を低減することが可能となるので、送風手段８の小型化、消費電力の低減、騒音の低減が可能となる。この結果、本体サイズをコンパクトにしながら、除湿効率を高めることができるのである。   As described above, the air that has been cooled to a temperature lower than room temperature by the heat absorber 7 is supplied to the radiator 5 of the refrigeration cycle, and the temperature of the air blowing passage that has passed through the moisture absorbing portion 9 of the dehumidifying rotor 11 is increased. By using another air passage, the radiator 5 can be cooled with air at a lower temperature, the cooling efficiency of the refrigeration cycle can be improved, and the dehumidifying efficiency of the dehumidifier can be improved. Furthermore, since the radiator can be cooled with low-temperature air, a small amount of air can be used to cool down the necessary heat, and the air volume can be reduced. Therefore, the blower 8 can be reduced in size and power consumption can be reduced. Noise can be reduced. As a result, the dehumidifying efficiency can be increased while reducing the size of the main body.

また、本実施形態において、さらに特徴的なのは、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から排出する第３送風路１８を備えたことである。   Further, in the present embodiment, a further characteristic is that a third air passage 18 that sucks air from the suction port 2, supplies it in the order of the heat absorber 7 and the heat radiator 5, and discharges it from the outlet 3 through the blower 8. It is to be prepared.

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は、加熱手段１２と除湿ロータ１１の下方を主に介して吸熱器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。   That is, in the 3rd ventilation path 18, the indoor air suck | inhaled from the suction inlet 2 is supplied to the heat absorber 7 mainly through the lower part of the heating means 12 and the dehumidification rotor 11, and is condensed by being cooled, Water is taken out as water droplets. Thereafter, the cooled air is supplied to the radiator 5 to cool the radiator 5. And the heat which took heat from the heat radiator 5 and the temperature rose is attracted | sucked by the ventilation means 8. FIG.

除湿ロータ１１の放湿部１０に送風する風量には、放湿部１０出口の空気をより結露しやすい空気（湿度が高く、温度が低い空気）とするため、最適な風量が存在する。一方、吸熱器７における冷却結露に対しても、その表面積や冷凍サイクルの動作熱量などにより、最適風量が存在する。これらの風量のアンバランスを解消するため、上述の第３送風路を設けることにより、吸熱器７への最適風量と、放湿部１０への最適風量をバランスさせることができる。   The amount of air blown to the moisture release unit 10 of the dehumidification rotor 11 has an optimum amount of air in order to make the air at the outlet of the moisture release unit 10 easier to condense (air with high humidity and low temperature). On the other hand, there is an optimum air flow for cooling condensation in the heat absorber 7 depending on the surface area, the operating heat amount of the refrigeration cycle, and the like. In order to eliminate these air volume imbalances, the optimal air volume to the heat absorber 7 and the optimal air volume to the moisture release unit 10 can be balanced by providing the above-described third air passage.

なお、除湿ロータ１１の放湿部１０と、吸熱器７との間には、第２送風路１７と第３送風路１８とが連通する連通風路２１を備えても良い。具体的には、連通風路２１は、除湿ロータ１１の放湿部１０周縁と吸熱器７との隙間である。すなわち、第３送風路１８を流れている室内の空気の一部が、連通風路２１を介して、第２送風路１７から吸熱器７へ流れても良い。   Note that a communication air passage 21 in which the second air passage 17 and the third air passage 18 communicate with each other may be provided between the moisture releasing portion 10 of the dehumidifying rotor 11 and the heat absorber 7. Specifically, the communication air passage 21 is a gap between the periphery of the moisture releasing portion 10 of the dehumidifying rotor 11 and the heat absorber 7. That is, part of the indoor air flowing through the third air passage 18 may flow from the second air passage 17 to the heat absorber 7 through the communication air passage 21.

第２送風路１７において、放湿部１０から流出する空気は、水分が多く含まれ、加熱手段１２の余熱も追加されており温度も高くなっており顕熱の比率が大きくなっているが、上述のように、この空気に連通風路２１を介して第３送風路１８からの室内空気を混合することにより、第２送風路１７における放湿部１０から吸熱器７へ流れる空気の温度が下がり、顕熱比率を下げることができ、より結露しやすい空気とすることができる。   In the second air passage 17, the air flowing out from the moisture release part 10 contains a lot of moisture, the residual heat of the heating means 12 is added, the temperature is high, and the ratio of sensible heat is large, As described above, the temperature of the air flowing from the moisture release unit 10 in the second air passage 17 to the heat absorber 7 is mixed by mixing the room air from the third air passage 18 through the communication air passage 21 with the air. The sensible heat ratio can be lowered and air can be more easily condensed.

このように、風量のアンバランスを解消し、吸熱器７上流の空気を結露しやすい空気とすることが可能となり、除湿装置の除湿効率を向上させることができるものである。   In this way, it is possible to eliminate the imbalance of the air volume, to make the air upstream of the heat absorber 7 easily dewed, and to improve the dehumidifying efficiency of the dehumidifying device.

また、本実施形態において、さらに特徴的なのは、吸込口２から空気を吸引し放熱器５に供給して吹出口３から排出する第４送風路１９を備えたことである。   Further, in the present embodiment, a further characteristic is that a fourth air passage 19 that sucks air from the suction port 2, supplies it to the radiator 5, and discharges it from the blower outlet 3 is provided.

すなわち、第４送風路１９において、吸込口２から吸い込まれた室内空気は、加熱手段１２と除湿ロータ１１と吸熱器７の下方を主に介して放熱器５に供給され、放熱器５を冷却したのち、送風手段８に吸引されることになる。   That is, in the 4th ventilation path 19, the indoor air suck | inhaled from the suction inlet 2 is supplied to the heat radiator 5 mainly through the lower part of the heating means 12, the dehumidification rotor 11, and the heat absorber 7, and cools the heat radiator 5. After that, the air is sucked by the blowing means 8.

吸熱器７における冷却結露に対しては、その表面積や冷凍サイクルの動作熱量などにより、最適風量が存在する。一方、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。上述のように第４送風路１９を配置することにより、放熱器５により多くの風量を供給することができるので、冷凍サイクルの冷却効率を向上させることができ、除湿装置の除湿効率を向上させることができるものである。   For cooling condensation in the heat absorber 7, there is an optimum air volume depending on the surface area, the operating heat amount of the refrigeration cycle, and the like. On the other hand, in the refrigeration cycle, effective cooling of the radiator 5 increases the cooling efficiency when the heat absorber 7 is cooled. By disposing the fourth air passage 19 as described above, a large amount of air can be supplied to the radiator 5, so that the cooling efficiency of the refrigeration cycle can be improved and the dehumidification efficiency of the dehumidifier is improved. It is something that can be done.

また、本実施形態において、さらに特徴的なのは、本体ケース１内に吸込口２側から順番に、除湿ロータ１１、吸熱器７、放熱器５、送風手段８を水平方向に並設するとともに、加熱手段１２を放湿部１０の風上側に並設したことである。   Further, in the present embodiment, what is more characteristic is that the dehumidifying rotor 11, the heat absorber 7, the heat radiator 5, and the air blowing means 8 are arranged in the main body case 1 in order from the suction port 2 side in the horizontal direction and heated. That is, the means 12 is arranged in parallel on the windward side of the moisture release section 10.

すなわち、風路方向に対して各要素部品の送風開口が面するように配置することができ、風路の曲がりなどのためにスペースを割く必要が無く、除湿装置のコンパクト化、送風抵抗の低減による送風手段８の小型化などの効果を有することになる。   That is, it can be arranged so that the air blowing openings of each component part face the air passage direction, so there is no need to divide the space for bending the air passage, etc., making the dehumidifier compact and reducing the air blowing resistance Thus, there is an effect such as downsizing of the air blowing means 8.

なお、第２送風路１７と第３送風路１８とは、吸込口２から送風手段８までの風路において、一直線となる風路を有しているので、送風抵抗を低減できる。   In addition, since the 2nd ventilation path 17 and the 3rd ventilation path 18 have the air path which becomes a straight line in the air path from the suction inlet 2 to the ventilation means 8, ventilation resistance can be reduced.

（実施の形態２）
図３は本発明の他の実施形態を示すもので、上記実施形態と同じ構成部分には、同じ符号を付している。 (Embodiment 2)
FIG. 3 shows another embodiment of the present invention, and the same reference numerals are given to the same components as those in the above embodiment.

本実施形態において、特徴的なのは、吸込口２から空気を吸引し吸湿部９、放熱器５の順に供給して吹出口３から排出する第５送風路２０を備えたことである。   In the present embodiment, what is characteristic is that a fifth air passage 20 is provided which sucks air from the suction port 2, supplies the air in the order of the moisture absorbing portion 9 and the radiator 5, and discharges the air from the outlet 3.

すなわち、放熱器５の上端は、吸熱器７の上端より上方に位置するように配置されている。これにより、第５送風路２０において、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となる。その後、吸熱器７の上方を介して、放熱器５に供給される。吸湿部９で温度が上昇している空気となるが、放熱器５の冷媒温度に比べると低い温度となるので、放熱器５に供給することで放熱器５の冷却に利用することができる。少しでも放熱器５への空気の供給量を増加することにより、放熱器５での放熱量を増加し、冷凍サイクルの冷却効率を増加することができる。   That is, the upper end of the heat radiator 5 is disposed so as to be located above the upper end of the heat absorber 7. Thereby, in the 5th ventilation path 20, the indoor air suck | inhaled from the suction inlet 2 is supplied to the moisture absorption part 9 of the dehumidification rotor 11. FIG. At this time, moisture in the air is adsorbed by the hygroscopic section 9 and becomes dry air. Furthermore, since heat of adsorption is generated when moisture is adsorbed, the indoor air is in a state where the humidity is reduced and the temperature is increased. Thereafter, the heat is supplied to the radiator 5 via the heat absorber 7. Although it becomes the air where the temperature is rising in the moisture absorption part 9, the temperature is lower than the refrigerant temperature of the radiator 5, so that it can be used for cooling the radiator 5 by supplying it to the radiator 5. By increasing the amount of air supplied to the radiator 5 as much as possible, the amount of heat released by the radiator 5 can be increased and the cooling efficiency of the refrigeration cycle can be increased.

このように、除湿装置の除湿効率を向上させることができるものである。   As described above, the dehumidifying efficiency of the dehumidifying device can be improved.

以上のように本発明は、吸込口から空気を吸引し吸湿部に供給して吹出口から排出する第１送風路と、吸込口から空気を吸引し放湿部、吸熱器、放熱器の順に供給して吹出口から排出する第２送風路とを備えた構成としたので、冷凍サイクルの放熱器には、吸熱器により室温より低い温度に冷却された空気を供給し、除湿ロータの吸湿部を通過した温度の上昇した空気の送風路とは別の送風路とすることにより、放熱器をより低い温度の空気で冷却することができ、冷凍サイクルの冷却効率を向上させ、除湿装置の除湿効率を向上させることができる。さらに、低温の空気で放熱器を冷却できるので、必要熱量を冷却するのに少ない量の空気で可能となり、風量を低減することが可能となるので、送風手段の小型化が可能となる。この結果、本体サイズをコンパクトにしながら、除湿効率を高めることができるのである。   As described above, the present invention sucks air from the suction port, supplies it to the moisture absorption part and discharges it from the outlet, and sucks air from the suction port in order of the moisture release part, the heat absorber, and the radiator. Since it was made into the structure provided with the 2nd ventilation path which supplies and discharges from a blower outlet, the air cooled to temperature lower than room temperature with a heat absorber is supplied to the heat radiator of a refrigerating cycle, and the moisture absorption part of a dehumidification rotor By using a different air flow path from the air flow path that has passed through the air, the radiator can be cooled with lower temperature air, improving the cooling efficiency of the refrigeration cycle and dehumidifying the dehumidifier Efficiency can be improved. Furthermore, since the radiator can be cooled with low-temperature air, a small amount of air can be used to cool down the required amount of heat, and the amount of air can be reduced, so that the size of the air blowing means can be reduced. As a result, the dehumidifying efficiency can be increased while reducing the size of the main body.

したがって、除湿装置として極めて有用なものとなる。   Therefore, it becomes extremely useful as a dehumidifying device.
