Abstract

<P>PROBLEM TO BE SOLVED: To solve the problem of the heater of conventional dehumidifying driers that its fabrication and attachment work requires a number of processes because it is necessary to bend and fold coiled nichrome wire in multiple into two stages as upper and lower, and fix it in a nearly fan-shaped form. <P>SOLUTION: The subject drier has a moisture-adsorbing material which adsorbs moisture. It causes air to be dehumidified to pass through a dehumidifying rotor 2 in the form of a rotating body so as to adsorb moisture in the air and thereby produce dry air while causing heated air generated by a heater 3 to pass through the rotor 2 having adsorbed the moisture so as to dry the rotor 2. With respect to the distance of the rotor 2 from a plane through which the heated air passes, the distance of the heater 3 arranged in the vicinity of the rotor 2 and upstream in the passage of the heated air is set to increase gradually from the peripheral to the central side of the rotor 2 in the radial direction. <P>COPYRIGHT: (C)2006,JPO&NCIPI

本発明は、除湿乾燥機に係り、より詳しくは、除湿ロータの吸着水分を蒸発させる加熱ヒータに関するものである。   The present invention relates to a dehumidifying dryer, and more particularly to a heater that evaporates adsorbed moisture of a dehumidifying rotor.

従来の除湿ロータと加熱ヒータを備えた除湿乾燥機においては、除湿ロータの再生部に送風する再生空気を加熱する加熱部の加熱ヒータを、除湿ロータの再生部に対応して、放射状に拡がる３枚の絶縁材に、コイル状ニクロム線を上下２段に、それぞれつずら折り状に曲げ固定し全体として略扇形にしていた（特許文献１）。
特開平１１−３００１４４号広報（第３頁〜第５頁、図２〜図１３） In a conventional dehumidifying dryer equipped with a dehumidifying rotor and a heater, the heater of the heating unit that heats the regenerated air blown to the regenerating unit of the dehumidifying rotor expands radially corresponding to the regenerating unit of the dehumidifying rotor 3 Coiled nichrome wires were bent and fixed in two upper and lower stages on a sheet of insulating material to form a substantially fan shape as a whole (Patent Document 1).
Japanese Laid-Open Patent Publication No. 11-300144 (Pages 3 to 5, FIGS. 2 to 13)

上記のように構成された従来の加熱ヒータでは、コイル状ニクロム線を上下２段に、それぞれつずら折り状に曲げ固定し全体として略扇形にする必要があり、加熱ヒータの製作、取付加工に多大の工数を要した。   In the conventional heater configured as described above, it is necessary to bend and fix the coiled nichrome wire in two upper and lower stages in a staggered manner to form a substantially fan shape as a whole. It took a lot of man-hours.

本発明は、上記のような課題を解決するためになされたもので、除湿ロータの乾燥用の加熱ヒータの製作、取付加工を容易とし、また、除湿ロータの再生部に未乾燥部を残さない除湿乾燥機を得ることを目的とする。   The present invention has been made to solve the above-described problems, and facilitates the manufacture and attachment processing of a heater for drying the dehumidifying rotor, and does not leave an undried portion in the regeneration portion of the dehumidifying rotor. The object is to obtain a dehumidifying dryer.

本発明に係る除湿乾燥機は、水分を吸着する吸湿材を有し、回転体である除湿ロータに被除湿空気を通過させ、該被除湿空気の水分を吸着させることにより乾燥空気を作成し、また、水分を吸着した除湿ロータに加熱ヒータで作成した加熱空気を通過させ、除湿ロータを乾燥させる除湿乾燥機であって、
除湿ロータの加熱空気通過面からの距離で、加熱空気の風路の上流側の除湿ロータ近傍に設けた加熱ヒータの距離を、除湿ロータの半径方向の外周側から中心側に向かって、次第に大きくなるようにしたものである。 The dehumidifying dryer according to the present invention has a moisture absorbing material that adsorbs moisture, passes the dehumidified air through a dehumidifying rotor that is a rotating body, and creates dry air by adsorbing moisture of the dehumidified air, Further, a dehumidifying dryer that passes the heated air created by the heater through the dehumidifying rotor that has adsorbed moisture, and dries the dehumidifying rotor,
The distance from the heating air passage surface of the dehumidification rotor gradually increases the distance of the heater provided in the vicinity of the dehumidification rotor on the upstream side of the air path of the heating air from the radial outer periphery side to the center side of the dehumidification rotor. It was made to become.

本発明の除湿乾燥機は、被除湿空気の水分を吸着した除湿ロータに加熱ヒータで作成した加熱空気を通過させ、除湿ロータを乾燥させるとともに、除湿ロータ近傍に設けた加熱ヒータの除湿ロータの加熱空気通過面からの距離を除湿ロータの半径方向の外周側から中心側に向かって、次第に大きくなるようにしたので、加熱ヒータは、除湿ロータの半径方向の外周側から中心側に延伸する単純な構造のヒータを傾斜設置すればよく、加熱ヒータの製作、取付加工が容易であり、また、加熱ヒータの熱放射により、除湿ロータの回転による中心側と外周側の回転速度の相違による乾燥むらを除去でき、再生部の水分を未乾燥部分なく均一に乾燥することができる。   The dehumidifying dryer of the present invention passes the heated air created by the heater through the dehumidifying rotor that has adsorbed the moisture of the air to be dehumidified, dries the dehumidifying rotor, and heats the dehumidifying rotor of the heater provided near the dehumidifying rotor. Since the distance from the air passage surface is gradually increased from the outer peripheral side in the radial direction of the dehumidifying rotor toward the central side, the heater is simply extended from the outer peripheral side in the radial direction of the dehumidifying rotor to the central side. It is only necessary to install a heater with a tilted structure, making it easy to manufacture and attach the heater, and due to the heat radiation of the heater, drying unevenness due to the difference in rotational speed between the center side and the outer periphery due to the rotation of the dehumidifying rotor It can be removed, and the moisture in the regenerating part can be uniformly dried without undried parts.

FIG. 1 is a schematic view showing the internal structure of the dehumidifying dryer according to Embodiment 1 of the present invention, and FIG. 2 is a perspective view showing the arrangement relationship of the heaters with respect to the dehumidifying rotor of FIG. These are side views which show the arrangement | positioning relationship of the heater with respect to the dehumidification rotor of FIG.
In FIG. 1, the present dehumidifying dryer includes a condenser 1 that condenses the moisture of the regenerated air in a housing, a dehumidifying rotor 2 that is a rotary hygroscopic body that passes dehumidified air that is room air and adsorbs the moisture, Heater 3 for heating air, indoor air that is dehumidified air taken in from the inlet of the housing, blower fan 4 that blows out as dry air from the outlet, water storage tank 5 that stores water condensed in the condenser 1, and wall portion The regenerative air path 7 that is the air path that circulates the regenerated air and the regenerative air path blower 6 that circulates the regenerated air in the regenerative air path are accommodated.

除湿ロータ２は、除湿ロータ回転用モータ（図示せず）で回転する回転円盤状体であり、ゼオライト等の水分吸着材を担持させ、空気が回転円盤状体の円盤面の前後に流通する通気性を有するものである。また、回転円盤状体は、被除湿空気を通過させ、被除湿空気から水分を吸湿する除湿部２ａと、加熱ヒータ３で加熱された加熱空気である再生空気を通過させ、蒸発水分として水分が除去される再生部２ｂとからなる。
凝縮器１は、再生風路７の一部分であり、この凝縮器１において、除湿ロータ３の再生部２ｂを通過し、吸湿水分を蒸発させた暖かい湿った再生風路７内の再生空気と、入口から取入れられた再生風路７外の室内空気とが熱交換することにより、再生風路７内の暖かい湿った再生空気が冷却され、水分が凝縮する。
再生風路７は、隔壁で形成され、風路内の再生風路用送風ファン６により再生空気を循環する風路であり、内部に加熱ヒータ３が設置され、通過する再生空気を加熱する。加熱ヒータ３の下流側で、加熱ヒータ３の近傍に、除湿ロータ２が、再生空気通過面を再生空気流れ方向に直交するように、回転中心を中心として回転可能に風路内に挿入されている。除湿ロータ２が挿入される再生風路７の上流側及び下流側開口部は、回転する除湿ロータ２の半径方向の外周側から中心側間に設けた略矩形等の長形状の開口を有し、この開口形状は、上流側の近傍に設置した加熱ヒータ３である後述の棒状加熱ヒータ３ａの外形形状に合せている。そして、再生風路７の開口部の開口に対応する除湿ロータ２の部分、即ち、開口から加熱空気が通過し、また、加熱ヒータ３の熱輻射が照射される部分が除湿ロータ２の再生部２ｂであり、その他の部分、即ち、被除湿空気が通過する部分が除湿部２ａである。
また、再生風路７の下部には、凝縮器１で凝縮した水を筐体下部の貯水タンク５に送る連通路が形成されている。
筐体内への被除湿空気の取入れ、及び除湿ロータ２の除湿部２ａ通過後の乾燥空気の吹出しは、送風ファン４で行う。 The dehumidifying rotor 2 is a rotating disk-like body that is rotated by a dehumidifying rotor rotating motor (not shown). The dehumidifying rotor 2 supports a moisture adsorbing material such as zeolite and allows air to flow before and after the disk surface of the rotating disk-like body. It has sex. Further, the rotating disk-shaped body passes the dehumidified air, passes the dehumidifying part 2a that absorbs moisture from the dehumidified air, and the regenerated air that is heated air heated by the heater 3, and the moisture is evaporated as moisture. The reproducing unit 2b is removed.
The condenser 1 is a part of the regeneration air passage 7, and in the condenser 1, the regeneration air in the warm and humid regeneration air passage 7 that has passed through the regeneration portion 2 b of the dehumidification rotor 3 and evaporated moisture absorption, Heat exchange with room air outside the regeneration air passage 7 taken in from the inlet cools the warm moist regeneration air in the regeneration air passage 7 and condenses moisture.
The regeneration air passage 7 is formed of a partition wall, and is an air passage through which the regeneration air is circulated by the air fan 6 for regeneration air passage in the air passage. The heater 3 is installed inside and heats the regeneration air passing therethrough. A dehumidification rotor 2 is inserted in the air passage so as to be rotatable about the rotation center so that the regeneration air passage surface is orthogonal to the regeneration air flow direction on the downstream side of the heater 3 in the vicinity of the heater 3. Yes. The upstream and downstream openings of the regeneration air passage 7 into which the dehumidifying rotor 2 is inserted have a long rectangular opening or the like provided between the outer peripheral side in the radial direction of the rotating dehumidifying rotor 2 and the center side. The opening shape is matched with the outer shape of a bar heater 3a, which will be described later, which is the heater 3 installed in the vicinity of the upstream side. The portion of the dehumidification rotor 2 corresponding to the opening of the opening of the regeneration air passage 7, that is, the portion where the heated air passes through the opening and the heat radiation of the heater 3 is irradiated is the regeneration portion of the dehumidification rotor 2. The other portion, that is, the portion through which the dehumidified air passes is the dehumidifying portion 2a.
In addition, a communication path is formed in the lower part of the regeneration air passage 7 to send the water condensed by the condenser 1 to the water storage tank 5 at the lower part of the casing.
The blower fan 4 performs intake of dehumidified air into the housing and blowing of dry air after passing through the dehumidifying part 2 a of the dehumidifying rotor 2.

次に、図２、図３により、除湿ロータ２に対する加熱ヒータ３の配置関係を説明する。
本実施の形態では、加熱ヒータ３は、Ｕ字状の棒状加熱ヒータ３ａを使用する。棒状加熱ヒータ３ａは、そのＵ字で形成する面を除湿ロータ２の空気通過面に対向させ、また、長手方向の一端側（リード線側）を除湿ロータ２の空気通過面の外周側とし、他端側を回転中心側とし、かつ、除湿ロータ２の再生部２ｂの空気通過面からの距離を外周側で小さく、中心側で大きくする。即ち、棒状加熱ヒータ３ａは除湿ロータ２の再生部２ｂの空気通過面に対して、半径方向に外周側から中心側に向かって、両者間の距離が大きくなるように傾斜して設置される。また、棒状加熱ヒータ３ａは、除湿ロータ２の再生部２ｂに対向させるが、接触しないように設置する。
除湿ロータ２の加熱による水分再放出は、「輻射」と「加熱空気の通過」の両方によるものであり、「輻射」の効果の比率は「加熱空気の通過」の効果よりも低い。
よって、棒状加熱ヒータ３をこように設置することにより、除湿ロータ２が回転したとき、回転速度の大きい外周側は、棒状加熱ヒータ３ａまでの距離が小さいため、加熱空気が高温のまま除湿ロータ２を通過し、また、回転速度の小さい中心側は棒状加熱ヒータ３ａまでの距離が大きいため、加熱空気がわずかに温度低下して除湿ロータ２を通過することになる。また、棒状加熱ヒータ３ａによる熱は、棒状加熱ヒータ３ａから除湿ロータ２の再生部２ｂに熱輻射により照射されるため、除湿ロータ２と棒状加熱ヒータ３ａとの距離が離れているほど、棒状加熱ヒータ３ａから除湿ロータ２への照射熱量は低下する。
これにより、除湿ロータ２の回転速度の速い外周側は、棒状ヒータ３ａとの距離が近いため、照射熱量が多く、かつ高温の加熱空気が通過することで短時間加熱され、回転速度の小さい中心側は、照射熱量が少なく、かつ外周部よりは低い温度の加熱空気が通過することで長時間加熱される。即ち、除湿ロータ２の再生部２ｂの半径方向の加熱が均一に行われる。
なお、除湿ロータ２の再生部２ｂには、加熱ヒータ３で加熱された加熱空気である再生空気を通過させ、全体的に乾燥は進行するが、除湿ロータ２の回転速度の速い外周側の乾燥は、回転速度の遅い中心側の乾燥より遅れる。即ち、再生部２ｂへ一応に加熱空気を送っても外周側ほど残存水分量は多くなる。
そこで、除湿ロータ２の再生部２ｂに対して、棒状加熱ヒータ３の傾斜を維持して、両者間の間隔を所定の間隔に調節することにより、除湿ロータ２の再生部２ｂの乾燥むらをなくすることができ、また、未乾燥部分をなくすことができる。除湿ロータ２は、回転させ風路内の再生部２ｂで、半径方向の外周側から中心側まで乾燥する。 Next, the positional relationship of the heater 3 with respect to the dehumidifying rotor 2 will be described with reference to FIGS.
In the present embodiment, the heater 3 uses a U-shaped rod heater 3a. The rod-shaped heater 3a has a U-shaped surface opposed to the air passage surface of the dehumidification rotor 2, and one end side (lead wire side) in the longitudinal direction is the outer peripheral side of the air passage surface of the dehumidification rotor 2, The other end side is set as the rotation center side, and the distance from the air passage surface of the regenerating portion 2b of the dehumidifying rotor 2 is decreased on the outer peripheral side and increased on the central side. That is, the rod-shaped heater 3a is installed to be inclined with respect to the air passage surface of the regeneration unit 2b of the dehumidifying rotor 2 so that the distance between the two increases from the outer peripheral side toward the central side in the radial direction. Further, the rod-shaped heater 3a is disposed so as not to come into contact with the regeneration unit 2b of the dehumidifying rotor 2 but facing it.
The moisture re-release due to heating of the dehumidifying rotor 2 is due to both “radiation” and “passing of heated air”, and the ratio of the effect of “radiation” is lower than the effect of “passing of heated air”.
Therefore, when the dehumidification rotor 2 rotates by installing the rod-shaped heater 3 in this way, the dehumidification rotor is kept at a high temperature because the distance to the rod-shaped heater 3a is small on the outer peripheral side where the rotation speed is large. 2 and the center side where the rotational speed is low has a large distance to the rod-shaped heater 3a, the heated air slightly drops in temperature and passes through the dehumidification rotor 2. Further, since the heat from the rod heater 3a is irradiated from the rod heater 3a to the regenerating part 2b of the dehumidification rotor 2 by heat radiation, the longer the distance between the dehumidification rotor 2 and the rod heater 3a, the more the rod heater The amount of heat applied from the heater 3a to the dehumidifying rotor 2 decreases.
As a result, the outer peripheral side where the rotational speed of the dehumidifying rotor 2 is fast is close to the rod-like heater 3a, so that the amount of irradiation heat is high and the high-temperature heated air passes through for a short time. The side is heated for a long time when heated air having a lower amount of irradiation heat and lower temperature than the outer peripheral portion passes. That is, the heating in the radial direction of the regeneration unit 2b of the dehumidifying rotor 2 is performed uniformly.
Note that the regeneration air, which is the heated air heated by the heater 3, is passed through the regeneration unit 2b of the dehumidification rotor 2, and the drying proceeds as a whole, but the dehumidification rotor 2 has a high rotational speed on the outer peripheral side. Is delayed from the drying at the center side where the rotation speed is slow. That is, even if heated air is sent to the regeneration unit 2b, the residual moisture amount increases toward the outer peripheral side.
Therefore, by maintaining the inclination of the bar heater 3 with respect to the regeneration unit 2b of the dehumidification rotor 2 and adjusting the interval between the two to a predetermined interval, drying unevenness of the regeneration unit 2b of the dehumidification rotor 2 is eliminated. In addition, the undried portion can be eliminated. The dehumidification rotor 2 is rotated and dried from the outer peripheral side in the radial direction to the central side by the regenerating unit 2b in the air passage.

本除湿乾燥機においては、入口から取り入れた被除湿空気である室内空気は、除湿ロータ２の除湿部２ｂを通過することにより、除湿ロータ２の除湿部２ａの水分吸着材により水分が除去され、乾燥空気として、吹出口から室内に吹出す。
また、除湿ロータ２の水分を吸湿した除湿部２ａは、回転により再生部２ｂとなり、加熱ヒータ３（棒状加熱ヒータ３ａ）により加熱された高温の加熱空気により乾燥する。この際、除湿ロータ２の再生部２ｂの面に対して、棒状加熱ヒータ３ａを半径方向に外周側から回転中心側に向けて両者間の距離が大きくなるように傾斜させ、かつ、所定の距離を保って設置したので、棒状加熱ヒータ３ａからの照射熱量と加熱空気の温度差による加熱量は、外周側の方が中心側より大きくなり、除湿ロータ２の回転による中心側と外周側の回転速度の相違による乾燥むらを除去でき、再生部２ｂの水分を未乾燥部分なく均一に乾燥することができる。
この際、加熱ヒータ３は、除湿ロータ２の半径方向の外周側から中心側に延伸する単純な構造のヒータを傾斜して設置すればよく、また、再生風路７の開口部の開口形状も矩形状の単純なものでよく、下熱ヒータ３の製作、設置が容易である。
また、再生風路７の下部に形成した連通路により、再生風路７の凝縮器１で凝縮した水分は、貯水タンク５に貯水される。 In the present dehumidifying dryer, the room air that is the dehumidified air taken in from the inlet passes through the dehumidifying part 2b of the dehumidifying rotor 2, whereby the moisture is removed by the moisture adsorbing material of the dehumidifying part 2a of the dehumidifying rotor 2, As dry air, it blows out into the room from the outlet.
Further, the dehumidifying part 2a that has absorbed the moisture of the dehumidifying rotor 2 becomes a regenerating part 2b by rotation, and is dried by high-temperature heated air heated by the heater 3 (rod heater 3a). At this time, the bar heater 3a is inclined with respect to the surface of the regeneration unit 2b of the dehumidifying rotor 2 in such a manner that the distance between the two increases from the outer peripheral side to the rotation center side in the radial direction, and a predetermined distance is reached. Therefore, the heating amount due to the temperature difference between the irradiation heat amount from the bar heater 3a and the heated air is larger on the outer peripheral side than on the central side, and the rotation on the central side and the outer peripheral side due to the rotation of the dehumidifying rotor 2 is performed. Unevenness of drying due to the difference in speed can be removed, and the moisture in the reproduction unit 2b can be uniformly dried without any undried portions.
At this time, the heater 3 may be installed by inclining a heater having a simple structure extending from the outer peripheral side in the radial direction of the dehumidifying rotor 2 to the center side, and the opening shape of the opening of the regeneration air passage 7 is also set. A simple rectangular shape may be used, and the lower heater 3 can be easily manufactured and installed.
Further, the water condensed in the condenser 1 of the regeneration air passage 7 is stored in the water storage tank 5 by the communication passage formed in the lower part of the regeneration air passage 7.

図４は、本除湿乾燥機の運転時の除湿ロータ２の除湿部２ａの表面温度分布の測定結果を示す図である。横軸は、除湿ロータ２の中心側（図３の半径Ｒ１）から外周側（図３の半径Ｒ２）までの距離であり、縦軸は、定常運転中のローター表面温度である。半径方向に均一な温度が得られた。
なお、再生空気である加熱空気を作成する加熱ヒータ３は、除湿ロータ２に輻射熱を放射する加熱ヒータ３とは別ヒータとしてもよく、同様の効果が得られる。
また、再生風路７の開口部の開口形状は、半径方向に長形の矩形状の単純なものに限らず、除湿ロータ２の円盤状体に倣って略扇形としてもよく、略扇形とすれば、その開口面積を適切な値とすることで、加熱空気による半径方向の外周側と中心側との乾燥むらも緩和できる。 FIG. 4 is a diagram showing the measurement result of the surface temperature distribution of the dehumidifying part 2a of the dehumidifying rotor 2 during operation of the present dehumidifying dryer. The horizontal axis is the distance from the center side (radius R1 in FIG. 3) to the outer peripheral side (radius R2 in FIG. 3) of the dehumidifying rotor 2, and the vertical axis is the rotor surface temperature during steady operation. A uniform temperature in the radial direction was obtained.
Note that the heater 3 that creates the heated air that is the regeneration air may be a separate heater from the heater 3 that radiates radiant heat to the dehumidifying rotor 2, and similar effects are obtained.
The opening shape of the opening of the regenerative air passage 7 is not limited to a simple rectangular shape that is long in the radial direction, and may be substantially fan-shaped following the disk-like body of the dehumidifying rotor 2. For example, by setting the opening area to an appropriate value, drying unevenness between the outer peripheral side and the central side in the radial direction due to heated air can be reduced.

実施の形態２．
図５は、実施の形態２の除湿乾燥機の除湿ロータに対する加熱ヒータの配置関係を示す斜視図であり、図６は、同じく、除湿ロータに対する加熱ヒータの配置関係を示す側面図である。それぞれ、実施の形態１の図２、図３に対応する図である。
実施の形態１の除湿乾燥機の加熱ヒータ３は、直線的に傾斜させたが、本実施の形態の除湿乾燥機はの加熱ヒータ３は、曲線を描いて傾斜させたものである。その他の構成等は同様であるので、以下、主として相違点を説明する。
本実施の形態の加熱ヒータ３は、実施の形態１のＵ字状の棒状加熱ヒータ３ａにおいて、Ｕ字状体の直線部を、一端側（除湿ロータ２の外周側と対向する側）から他端側（除湿ロータ２の回転中心側と対向する側）の長手方向に、除湿ロータ２側が凹となるように連続的に曲げた（図５、図６の例では円弧状になるように曲げた）Ｕ字体としたものである。即ち、実施の形態１では、除湿ロータ２の再生部２ｂの面に対して、棒状加熱ヒータ３ａを半径方向に外周側から回転中心側に向けて両者間の距離が大きくなるように直線的に傾斜させたのに対して、本実施の形態では、曲線を描いて半径方向に全体的には同様に傾斜させ曲線加熱ヒータ３ｂとした。 Embodiment 2. FIG.
FIG. 5 is a perspective view showing the positional relationship of the heater with respect to the dehumidifying rotor of the dehumidifying dryer according to the second embodiment, and FIG. 6 is a side view showing the positional relationship of the heater with respect to the dehumidifying rotor. FIG. 4 is a diagram corresponding to FIGS. 2 and 3 of the first embodiment, respectively.
Although the heater 3 of the dehumidifying dryer of Embodiment 1 is linearly inclined, the heater 3 of the dehumidifying dryer of this embodiment is inclined in a curved line. Since other configurations are the same, differences will be mainly described below.
The heater 3 of the present embodiment is different from the U-shaped rod-shaped heater 3a of the first embodiment in that the straight portion of the U-shaped body is different from one end side (the side facing the outer peripheral side of the dehumidifying rotor 2). In the longitudinal direction of the end side (the side opposite to the rotation center side of the dehumidifying rotor 2), the dehumidifying rotor 2 side is continuously bent so as to be concave (in the example of FIGS. 5 and 6, bent so as to have an arc shape) E) U-shaped. That is, in the first embodiment, the rod heater 3a is linearly arranged with respect to the surface of the regeneration unit 2b of the dehumidifying rotor 2 so that the distance between the two increases from the outer peripheral side to the rotation center side in the radial direction. In contrast to the inclination, in the present embodiment, a curved heater is formed by drawing a curved line and inclining in the same manner in the radial direction.

本曲線加熱ヒータ３ｂにおいては、除湿ロータ２の再生部２ｂの面に対して、棒状加熱ヒータ３ａを半径方向に外周側から回転中心側に向けて両者間の距離が大きくなるように、曲線を描いて傾斜させたので、除湿ロータ２の回転による中心側と外周側の回転速度の相違による乾燥むらを同様に除去できる。さらに、本実施の形態においては、被除湿空気の空気条件の相違である除湿部２ａの半径方向の風量の相違、加熱空気の空気条件の相違である再生部２ｂの半径方向の風量や温度の相違、即ち、再生部２ｂの半径方向に被除湿空気の空気条件、加熱空気の空気条件により吸湿量の相違がある場合にも、曲率を選定することにより対応した加熱が容易となり、乾燥むらを除去でき、再生部２ｂの水分を未乾燥部分なく均一に乾燥することができる。
また、本除湿乾燥機は、除湿ロータ２の回転による中心側と外周側の回転速度の相違と、除湿ロータ２の除湿部２ａの半径方向の被除湿空気の空気条件の相違及び／又は除湿ロータ２の再生部２ｂの半径方向の加熱空気の空気条件の相違とを考慮して、加熱ヒータ３を半径方向に外周側から回転中心側に向けて両者間の距離を直線的に及び／又は曲線的に変化させて設置すれば、その寸法の微調整を行うことで、より効果的に再生部２ｂの水分を未乾燥部分なく均一に乾燥することができる。 In this curved heater 3b, a curve is formed so that the distance between the two becomes larger with respect to the surface of the regenerating part 2b of the dehumidifying rotor 2 from the outer periphery side to the rotation center side in the radial direction. Since it is drawn and inclined, drying unevenness due to the difference in rotational speed between the central side and the outer peripheral side due to the rotation of the dehumidifying rotor 2 can be similarly removed. Further, in the present embodiment, the difference in the air volume in the radial direction of the dehumidifying part 2a, which is the difference in the air condition of the dehumidified air, and the difference in the air volume and temperature in the radial direction of the regenerating part 2b, which is the difference in the air condition of the heated air. Even when there is a difference in moisture absorption due to the air condition of the dehumidified air and the heated air in the radial direction of the regeneration unit 2b, the corresponding heating is facilitated by selecting the curvature, and uneven drying is caused. It is possible to remove the moisture in the regenerating unit 2b uniformly without undried portions.
In addition, the present dehumidifying dryer has a difference in rotational speed between the center side and the outer peripheral side due to the rotation of the dehumidifying rotor 2, a difference in air condition of the dehumidified air in the radial direction of the dehumidifying portion 2a of the dehumidifying rotor 2, and / or a dehumidifying rotor. In consideration of the difference in the air condition of the heated air in the radial direction of the two regenerating parts 2b, the distance between the heater 3 is linearly and / or curved in the radial direction from the outer peripheral side to the rotation center side. If it is installed in a changed manner, the moisture in the regenerating unit 2b can be more effectively dried without undried parts by finely adjusting the dimensions.
