また、第２送風手段８は熱交換器５を冷却するとともに、除湿ローター２に水分を吸着させて吹出口１２から室内に乾燥空気を送出している。前面が開口した略扇形形状の箱体１０ａは発熱手段１０を保持するとともに、箱体１０ａの開口面を覆うように、１つの出口部１１ａを備えた蓋部１１が結合している。また箱体１０ａには第１送風手段７からの送風を取り込む１つの入口部１０ｂを備え、蓋部１１の出口部１１ａは発熱手段１０で加熱された空気を除湿ローター２へと吹き出すものである。   The second air blowing means 8 cools the heat exchanger 5, adsorbs moisture to the dehumidifying rotor 2, and sends dry air from the air outlet 12 into the room. The substantially fan-shaped box body 10a whose front surface is open holds the heat generating means 10, and a lid portion 11 having one outlet portion 11a is joined so as to cover the opening surface of the box body 10a. Further, the box body 10a is provided with one inlet 10b for taking in the air blown from the first blower 7, and the outlet 11a of the lid 11 blows out the air heated by the heating means 10 to the dehumidifying rotor 2. .

また、発熱手段１０は箱体１０ａ内で加熱ヒーター１０ｅを収納する枠体１６を備え、この枠体１６の両側面に第１開口穴１６ａと第２開口穴１６ｂを設け、複数の通風路として枠体１６の表裏面をそれぞれ通過する表通風路１０ｃと裏通風路１０ｄを設けている。表通風路１０ｃは箱体１０ａの入口部１０ｂから第１開口穴１６ａ、加熱ヒーター１０ｅおよび蓋部１１の出口部１１ａに連通し、裏通風路１０ｄは箱体１０ａの入口部１０ｂから枠体１６の裏面、第２開口穴１６ｂ、加熱ヒーター１０ｅおよび蓋部１１の出口部１１ａに連通して設けている。   The heat generating means 10 includes a frame body 16 that houses the heater 10e in the box body 10a. The first opening hole 16a and the second opening hole 16b are provided on both side surfaces of the frame body 16 to form a plurality of ventilation paths. The front ventilation path 10c and the back ventilation path 10d which respectively pass the front and back of the frame 16 are provided. The front air passage 10c communicates from the inlet 10b of the box 10a to the first opening hole 16a, the heater 10e, and the outlet 11a of the lid 11, and the back air passage 10d extends from the inlet 10b of the box 10a to the frame 16. The second opening hole 16b, the heater 10e, and the outlet portion 11a of the lid portion 11 are provided in communication with each other.

また、枠体１６内で加熱ヒーター１０ｅを支持するために縦横に配置された複数の縦絶縁板１３および横絶縁板１４備え、枠体１６の側面に第１開口穴１６ａを設け、横絶縁板１４は第１開口穴１６ａから蓋部１１の出口部１１ａまでの表通風路１０ｃを複数の通風路として分離している。   In addition, a plurality of vertical insulating plates 13 and horizontal insulating plates 14 arranged vertically and horizontally to support the heater 10e in the frame body 16 are provided, and a first opening hole 16a is provided on a side surface of the frame body 16 to provide a horizontal insulating plate. 14 isolate | separates the surface ventilation path 10c from the 1st opening hole 16a to the exit part 11a of the cover part 11 as a some ventilation path.

さらに、加熱ヒーター１０ｅを支持する縦絶縁板１３の高さを順次変えることにより、加熱ヒーター１０ｅへ供給する風量をバランスよく適正に配分している。   Further, by sequentially changing the height of the vertical insulating plate 13 that supports the heater 10e, the amount of air supplied to the heater 10e is appropriately distributed in a balanced manner.

上記構成により、箱体１０ａは発熱手段１０として枠体１６に収納された加熱ヒーター１０ｅを保持するとともに、この箱体１０ａの開口面を覆う蓋部１１とを有している。   With the above configuration, the box 10a has the heater 11e housed in the frame 16 as the heat generating means 10, and has the lid 11 that covers the opening surface of the box 10a.

第１送風手段７からの送風を箱体１０ａの側方に設けた１つの入口部１０ｂより取り込み、枠体１６内の加熱ヒーター１０ｅで加熱して、蓋部１１に設けた１つ出口部１１ａより高温空気を除湿ローター２へ吹出している。このとき箱体１０ａの内部に加熱ヒーター１０ｅを通過する通風路１５を複数形成して、箱体１０ａ内の気流を分散することにより、加熱ヒーター１０ｅへの風速分布のアンバランスを調整することができるので、除湿ローター２表面を均一に加熱できるものである。   The air blown from the first air blowing means 7 is taken in from one inlet 10b provided on the side of the box 10a, heated by the heater 10e in the frame 16, and one outlet 11a provided in the lid 11 Higher temperature air is blown out to the dehumidifying rotor 2. At this time, by forming a plurality of ventilation passages 15 passing through the heater 10e inside the box 10a and dispersing the airflow in the box 10a, the imbalance of the wind speed distribution to the heater 10e can be adjusted. Therefore, the surface of the dehumidifying rotor 2 can be heated uniformly.

すなわち、箱体１０ａに設けた１つの入口部１０ｂから、蓋部１１に設けた１つの出口部１１ａに至る風路を、枠体１６の表側を通る表通風路１０ｃと枠体１６の裏側を通る裏通風路１０ｄの２つに分け、また枠体１６の両側面に設けた第１開口穴１６ａと第２開口穴１６ｂに各風路をそれぞれ通過させることにより、裏通風路１０ｄは入口部１０ｂとは反対側にある通風の行き届かない加熱ヒーター１０ｅへ確実に通風することができるので、加熱ヒーター１０ｅへの風速分布のアンバランスを調整して温風温度を均一化することができる。   That is, the air passage from one inlet portion 10 b provided in the box 10 a to one outlet portion 11 a provided in the lid portion 11, the front air passage 10 c passing through the front side of the frame body 16 and the back side of the frame body 16. The back ventilation path 10d is divided into two through passages, and each ventilation path is passed through a first opening hole 16a and a second opening hole 16b provided on both side surfaces of the frame body 16, so that the back ventilation path 10d can be Since it is possible to surely ventilate the heater 10e on the side opposite to the vent 10b where ventilation is not achieved, it is possible to make the warm air temperature uniform by adjusting the imbalance of the wind speed distribution to the heater 10e.

さらに、表通風路１０ｃにおいて、枠体１６内の加熱ヒーター１０ｅを横断するように配置された横絶縁板１４が通風を遮蔽する仕切りとなり、複数の通風路１５を形成することができる。すなわち箱体１０ａの入口部１０ｂから第１開口穴１６ａを通過する表通風路１０ｃを、横絶縁板１４により枠体１６内で複数の通風路１５に分離できるので、枠体１６内を通過する気流を広く分散することができ、加熱ヒーター１０ｅへの風速分布を均等に調整することができる。   Furthermore, in the front ventilation path 10c, the horizontal insulating plate 14 disposed so as to cross the heater 10e in the frame body 16 serves as a partition that blocks ventilation, and a plurality of ventilation paths 15 can be formed. That is, the front ventilation path 10c that passes through the first opening hole 16a from the inlet 10b of the box 10a can be separated into the plurality of ventilation paths 15 in the frame 16 by the lateral insulating plate 14, and therefore passes through the frame 16. The airflow can be widely dispersed, and the wind speed distribution to the heater 10e can be adjusted uniformly.

また、加熱ヒーター１０ｅを支持する縦絶縁板１３の高さを順次高くすることにより、箱体１０ａの入口部１０ｂから第１開口穴１６ａを通過して枠体１６内に流入する通風量を、高さの異なる縦絶縁板１３により均等に分配することができ、加熱ヒーター１０ｅへの通過風量を均等に調整して、満遍なく温風を除湿ローター２に供給することができる。   Further, by sequentially increasing the height of the vertical insulating plate 13 that supports the heater 10e, the amount of air flowing from the inlet 10b of the box 10a through the first opening hole 16a into the frame 16 is reduced. The vertical insulating plates 13 having different heights can be evenly distributed, and the amount of air passing through the heater 10e can be adjusted uniformly so that warm air can be uniformly supplied to the dehumidifying rotor 2.

（実施の形態２）
図６に示すように、蓋部１１の開口部１１ａの端辺に沿って段差部１１ｂを形成し、加熱ヒーター１０ｅに近接して設けている。 (Embodiment 2)
As shown in FIG. 6, the step part 11b is formed along the edge of the opening part 11a of the cover part 11, and it has provided in proximity to the heater 10e.

上記構成により、蓋部１１の開口部１１ａの端辺は段差部１１ｂを有しているので、近接する加熱ヒーター１０ｅから熱を受けた場合でも、蓋部１１の開口部１１ａの端辺は熱膨張によって変形しにくくなるため、蓋部１１と除湿ローター２の隙間を適正に保つことができ、閉循環させている空気の漏れを生じないようにして、除湿ローター２の再生効率を維持することにより、除湿能力を安定して発揮できる除湿装置を提供することができる。   With the above configuration, the edge of the opening 11a of the lid 11 has the stepped portion 11b. Therefore, even when heat is received from the adjacent heater 10e, the edge of the opening 11a of the lid 11 is heated. Since it becomes difficult to be deformed by expansion, the gap between the lid portion 11 and the dehumidifying rotor 2 can be properly maintained, and the regeneration efficiency of the dehumidifying rotor 2 can be maintained without causing leakage of the closed and circulated air. Thus, it is possible to provide a dehumidifying device that can stably exhibit the dehumidifying ability.

（実施の形態３）
図７および図８に示すように、加熱ヒーター１０ｅを収納する枠体１６は、蓋部１１の開口部１１ａの端辺に沿う位置に折曲部１６ｃを設け、蓋部１１の開口部１１ａの端辺を平板状に形成するとともに、折曲部１６ｃと重合する構成としている。 (Embodiment 3)
As shown in FIGS. 7 and 8, the frame 16 that houses the heater 10 e is provided with a bent portion 16 c at a position along the edge of the opening 11 a of the lid 11, The end side is formed in a flat plate shape and overlaps with the bent portion 16c.

上記構成により、蓋部１１の開口部１１ａの端辺に沿う位置に、枠体１６の折曲部１６ｃを設けているので、加熱ヒーター１０ｅから温風熱などを受けた場合でも、枠体１６の折曲部１６ｃは熱膨張によって変形しにくいため、蓋部１１の開口部１１ａの端辺が平板状であっても熱変形を防ぐことができ、蓋部１１の開口部１１ａの形状を簡素化できるとともに、蓋部１１と除湿ローター２の隙間を適正に保つことができる。したがって、蓋部１１と除湿ローター２の隙間から循環空気の漏れが防止できるので、除湿ローター２の再生効率を維持することができ、除湿能力を安定して発揮できる除湿装置を提供することができる。   With the above configuration, since the bent portion 16c of the frame body 16 is provided at a position along the edge of the opening 11a of the lid portion 11, the frame body 16 can be used even when receiving hot air heat from the heater 10e. Since the bent portion 16c is not easily deformed by thermal expansion, it is possible to prevent thermal deformation even when the edge of the opening 11a of the lid 11 is flat, and the shape of the opening 11a of the lid 11 is simple. And the gap between the lid 11 and the dehumidifying rotor 2 can be kept appropriate. Therefore, since the leakage of circulating air can be prevented from the gap between the lid 11 and the dehumidifying rotor 2, the regeneration efficiency of the dehumidifying rotor 2 can be maintained, and a dehumidifying device that can stably exhibit the dehumidifying ability can be provided. .
