Description

【０００１】
【発明の属する技術分野】
本発明は電気除湿機に関する。さらに詳しくは、送風ファンの回転数を増加させず、しかも本体内部の負圧を上昇させることなく、大風量を得ることができる電気除湿機に関する。
【０００２】
【従来の技術】
従来より家庭用電気除湿機として、吸放湿性を有するゼオライトなどの吸湿素子を用いた乾式除湿機がある。
【０００３】
従来の乾式除湿機は、送風ファンの上流側に向かって、吸湿素子と、吸湿素子から放湿された湿気を冷却して結露させるための熱交換器とが順に配設されている。したがって、送風ファンの負圧によって本体内部に吸い込まれる空気は、まず熱交換器を通過し、ついで吸湿素子を通過するときに空気に含まれる水分が吸湿素子へ吸湿され、そののち、乾いた空気が室内へ放出される。
【０００４】
吸湿素子に吸湿された水分は、除湿機内部に設けられたヒータで加熱された空気を吸湿素子に通過させることにより、吸湿素子から放湿される。放湿された湿気は、前述の熱交換器で冷却されて結露したのち、タンクに貯められる。
【０００５】
【発明が解決しようとする課題】
熱交換器の冷却効率および室内で乾かされる洗濯物の乾燥効率を向上させるためには、風量を増加させることが効果的である。しかし、吸湿素子の通気抵抗が高いため、風量を増やすためには送風ファンの回転数を上げる必要があり、騒音の原因になるという問題がある。
【０００６】
また、吸湿素子の通気抵抗が高いため、風量を増やせば本体内の圧力が大きく下がり、吸湿素子から放湿された蒸気が熱交換器で冷却されて結露を行なう循環経路外に排出され、その結果、除湿効率が低下するという問題がある。
【０００７】
本発明はかかる問題を解消するためになされたものであり、送風ファンの回転数の増加や本体内部の負圧の上昇を生じることなく、大風量を得ることができる電気除湿機を提供することを目的とする。
【０００８】
【課題を解決するために手段】
本発明の電気除湿機は、（ａ）本体内部に配設され、本体の吸気口から外部の空気を吸い込み、本体の排気口から空気を排気するための送風ファンと、
（ｂ）該送風ファンの上流側に設けられ、前記吸気口から吸い込まれた空気に含まれる水分を吸湿する吸湿素子と、
（ｃ）該吸湿素子に吸湿された水分を取り除くために当該吸湿素子を通過する空気を加熱する加熱手段と、
（ｄ）該吸湿素子の上流側に設けられ、当該吸湿素子から放湿された湿気を冷却して結露させるための熱交換器とを備えてなる電気除湿機であって、
前記熱交換器と送風ファンとのあいだに前記吸湿素子をバイパスする通路を設けると共に、前記バイパス通路を開閉するためのシャッタをさらに備えてなることを特徴としている。
【０００９】
前記熱交換器と送風ファンとのあいだに密閉された空間部が形成され、該空間部の上流側部分と下流側部分とが隔壁によって分割され、該隔壁には、前記吸湿素子に連通する連通孔および前記吸湿素子をバイパスするバイパス孔が形成されてなるのが好ましい。
【００１１】
【発明の実施の形態】
つぎに図面を参照しながら本発明の電気除湿機をさらに詳細に説明する。図１は本発明の電気除湿機の一実施の形態を示す本体内部の吸湿素子付近を前方から見た断面説明図、図２は図１の電気除湿機の本体を前後方向に切断した断面説明図、図３は図１の電気除湿機の正面図、図４は図１の本体内部の熱交換器付近を前方から見た断面説明図、および図５は図１の本体を幅方向に切断して上から見た断面説明図である。
【００１２】
図１〜５に示される電気除湿機は、本体１の前面（図２の左側）から本体１の前後方向に沿って熱交換器２、吸湿素子３および送風ファン４が順に配設されている。本体１の前面の吸気口５から吸い込まれた空気は、熱交換器２および吸湿素子３を通って送風ファン４へ行くメインの吸気ルートＲ１、ならびに熱交換器２から吸湿素子３をバイパスしてバイパス孔６を通って送風ファン４へ到達するバイパスルートＲ２の２つの経路を通る。
【００１３】
メインの吸気ルートＲ１に設けられた円板状の吸湿素子３は、吸放湿性を有するゼオライトなどの材料をハニカム構造にしたものなどが用いられているため、通気抵抗が大きい。しかし、図１〜２に示されるように、メインの吸気ルートＲ１とは別に吸湿素子３をバイパスするバイパスルートＲ２を有しているため、送風ファン４の回転数を上げたり、本体内部の負圧を大幅に下げなくても大風量の空気を得ることができる。
【００１４】
図１〜２に示される除湿機の場合、熱交換器２と送風ファン４とのあいだに密閉された空間部７が形成され、該空間部７の上流側部分７ａと下流側部分７ｂとが隔壁８によって分割されている。隔壁８には、吸湿素子３に連通する連通孔９および吸湿素子３をバイパスするバイパス孔６が形成されている。したがって、１枚の隔壁８に連通孔９およびバイパス孔６を形成した簡単な構造で、２つの吸気ルートＲ１、Ｒ２を得ることができる。
【００１５】
メインの吸気ルートＲ１の流量Ｑ１およびバイパスルートＲ２の流量Ｑ２は、適宜設定すればよいが、たとえば、Ｑ１：Ｑ２＝２：１程度の割合で設定するのが好ましい。
【００１６】
また、図示されていないが、風量の調節に応じてバイパスルートＲ２を開閉するためのシャッタをさらに備えてもよい。たとえば、前記隔壁８のバイパス孔６に手動または電動で開閉されるシャッタを設ければ、風量を弱くして送風する場合には、バイパス孔６をシャッタで閉じることにより、吸湿素子３を通過する乾燥した空気だけを本体外部へ排出することができる。
【００１７】
本体１の前方側（図２における左側）に配設された熱交換器２は、図２および図４に示されるように、吸気口５からの空気が通る複数の通気孔１１が形成された中空体からなる。本発明では、熱交換器の形状や構造についてはとくに限定するものではなく、複数の中空パイプに放熱フィンを設けたものを熱交換器として用いてもよい。
【００１８】
さらに、熱交換器２には、図２および図５に示されるように、循環用ファン１２、および加熱手段であるヒータ１３に連通する循環経路１４が接続されている。なお、図５の１５は、循環用ファン１２を回転駆動させるためのモータである。
【００１９】
また、図２および図４に示されるように、熱交換器２の下端の位置には、排水口１６が形成され、熱交換器２によって結露された除湿水は、この排水口１６を通して下方のタンク１７へ集められる。
【００２０】
送風ファン４は、図２に示されるように、本体１の前方から空気を吸って送風ファン２の半径方向に排気する、いわゆる遠心ファンであり、ファン４の中央にはファン２を駆動するための駆動モータ１８が設置されている。
【００２１】
図２〜３に示されるように、本体１の前面に複数のスリットからなる吸気口５が形成され、本体１の上面には吸湿素子３を通過して吸湿された乾いた空気を室内へ排気するための排気口１９が形成されている。
【００２２】
本実施の形態の電気除湿機では、図１〜４に示されるように、室内の湿気を帯びた空気は、吸気口５より吸気され、熱交換器２を通過し、送風ファン４によって吸湿素子３へ送風される。湿気を帯びた空気は、吸湿素子３を通過する際に水分が吸湿され、乾燥した空気となって本体外へ排気される。それとともに、バイパス孔６を通して吸湿素子３を通過せずに送風ファン４によって排気される空気も得ることができる。したがって、メイン吸気ルートＲ１およびバイパスルートＲ２によって得られる大風量の空気によって、熱交換器２の冷却および洗濯物の乾燥を効果的に行なうことができる。
【００２３】
吸湿素子３は、駆動モータ１８によって回転され、室内の空気を吸湿し、そののち、ヒータ１３に対向する加熱領域２０に入り、加熱された空気が通過することにより、吸湿素子３に吸湿された水分が放湿される。放湿された水分は、連通管２１を通して図１の本体前方側の熱交換器２内を通過することにより冷却されて結露し、除湿水として排水口１６を通してタンク１７に貯められる。
【００２４】
また、本実施の形態の除湿機では、図１および図５に示されるように、ヒータ１３を有する加熱領域２０と並列に、バイパス領域２２が配置されている。そのため、循環経路１４を流れる空気の一部は、ヒータ１３で加熱されて吸湿素子３の放湿に用いられるが、その他の空気は、バイパス領域２２を通して吸湿素子３に吹きつけて吸湿素子３の冷却に用いられる。したがって、図１に示される吸湿素子３を反時計方向に回転させた場合、吸湿素子３を通過する空気をヒータ１３で加熱して当該吸湿素子３に吸着された水分を放湿したのち、バイパス領域２２を通る空気によって吸湿素子３が冷却されるので、前記メインの吸気ルートＲ１を流れる空気の除湿を効果的に行なうことができる。
【００２５】
【発明の効果】
本発明によれば、バイパス孔を形成することによって、吸湿素子を通る風路と、当該吸湿素子をバイパスする風路とを構成することができるので、送風ファンの回転数の増加や本体内部の負圧の上昇を生じることなく、大風量を得ることができる。さらに、排気口より大風量の風が吹き出されるので、洗濯物を素早く乾燥させることができる。また、シャッタにより前記バイパス通路を開閉することで、風量の調節を行なうことができる。

BACKGROUND OF THE INVENTION
The present invention relates to an electric dehumidifier. More specifically, the present invention relates to an electric dehumidifier that can obtain a large air volume without increasing the rotational speed of the blower fan and without increasing the negative pressure inside the main body.
[0002]
[Prior art]
Conventionally, as a household electric dehumidifier, there is a dry dehumidifier using a hygroscopic element such as zeolite having hygroscopic properties.
[0003]
In a conventional dry dehumidifier, a hygroscopic element and a heat exchanger for cooling and condensing moisture released from the hygroscopic element are sequentially arranged toward the upstream side of the blower fan. Therefore, the air sucked into the main body by the negative pressure of the blower fan first passes through the heat exchanger, and then the moisture contained in the air is absorbed into the hygroscopic element when passing through the hygroscopic element, and then the dry air Is released into the room.
[0004]
The moisture absorbed by the moisture absorption element is released from the moisture absorption element by allowing the air heated by the heater provided inside the dehumidifier to pass through the moisture absorption element. The released moisture is cooled by the heat exchanger described above and condensed, and then stored in a tank.
[0005]
[Problems to be solved by the invention]
In order to improve the cooling efficiency of the heat exchanger and the drying efficiency of the laundry to be dried indoors, it is effective to increase the air volume. However, since the ventilation resistance of the hygroscopic element is high, it is necessary to increase the rotational speed of the blower fan in order to increase the air volume, which causes a problem of noise.
[0006]
In addition, because the ventilation resistance of the moisture absorption element is high, if the air volume is increased, the pressure in the main body will be greatly reduced, and the vapor released from the moisture absorption element will be cooled by the heat exchanger and discharged outside the circulation path where condensation occurs. As a result, there is a problem that the dehumidification efficiency is lowered.
[0007]
The present invention has been made to solve such a problem, and provides an electric dehumidifier capable of obtaining a large air flow without causing an increase in the rotational speed of a blower fan or an increase in negative pressure inside a main body. With the goal.
[0008]
[Means for solving the problems]
The electric dehumidifier of the present invention is (a) disposed inside the main body, sucks external air from the air intake port of the main body, and exhausts air from the exhaust port of the main body,
(B) a hygroscopic element that is provided on the upstream side of the blower fan and absorbs moisture contained in the air sucked from the air inlet;
(C) a heating means for heating the air passing through the hygroscopic element in order to remove moisture absorbed by the hygroscopic element;
(D) An electric dehumidifier provided on the upstream side of the hygroscopic element, and comprising a heat exchanger for cooling and dehumidifying moisture released from the hygroscopic element,
Rutotomoni provided a passage bypassing the moisture absorbing element between the blower fan and the heat exchanger, and characterized in that it comprises further a shutter for opening and closing the bypass passage.
[0009]
A sealed space portion is formed between the heat exchanger and the blower fan, and an upstream portion and a downstream portion of the space portion are divided by a partition, and the partition communicates with the hygroscopic element. It is preferable that a bypass hole for bypassing the hole and the hygroscopic element is formed.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, the electric dehumidifier of the present invention will be described in more detail with reference to the drawings. FIG. 1 is a cross-sectional explanatory view of the vicinity of a moisture-absorbing element inside a main body showing an embodiment of the electric dehumidifier of the present invention, and FIG. FIG. 3, FIG. 3 is a front view of the electric dehumidifier of FIG. 1, FIG. 4 is a cross-sectional explanatory view of the vicinity of the heat exchanger inside the main body of FIG. 1, and FIG. And it is sectional explanatory drawing seen from the top.
[0012]
In the electric dehumidifier shown in FIGS. 1 to 5, a heat exchanger 2, a moisture absorption element 3, and a blower fan 4 are sequentially arranged from the front surface of the main body 1 (left side in FIG. 2) along the front-rear direction of the main body 1. . The air sucked from the air inlet 5 on the front surface of the main body 1 bypasses the main intake route R1 going to the blower fan 4 through the heat exchanger 2 and the hygroscopic element 3, and the hygroscopic element 3 from the heat exchanger 2. It passes through two paths of a bypass route R2 that reaches the blower fan 4 through the bypass hole 6.
[0013]
The disk-shaped moisture absorption element 3 provided in the main intake route R1 has a high ventilation resistance because a material such as zeolite having a moisture absorption / release property having a honeycomb structure is used. However, as shown in FIGS. 1 and 2, since the bypass route R2 that bypasses the moisture absorbing element 3 is provided separately from the main intake route R1, the rotational speed of the blower fan 4 is increased, and A large amount of air can be obtained without greatly reducing the pressure.
[0014]
In the case of the dehumidifier shown in FIGS. 1 and 2, a sealed space portion 7 is formed between the heat exchanger 2 and the blower fan 4, and an upstream portion 7 a and a downstream portion 7 b of the space portion 7 are formed. It is divided by a partition wall 8. In the partition wall 8, a communication hole 9 that communicates with the hygroscopic element 3 and a bypass hole 6 that bypasses the hygroscopic element 3 are formed. Therefore, two intake routes R1 and R2 can be obtained with a simple structure in which the communication hole 9 and the bypass hole 6 are formed in one partition wall 8.
[0015]
The flow rate Q1 of the main intake route R1 and the flow rate Q2 of the bypass route R2 may be set as appropriate. For example, it is preferable to set the flow rate Q1: Q2 = 2: 1.
[0016]
Although not shown, a shutter for opening and closing the bypass route R2 according to the adjustment of the air volume may be further provided. For example, if the bypass hole 6 of the partition wall 8 is provided with a shutter that is opened or closed manually or electrically, when the air volume is reduced and the air is blown, the bypass hole 6 is closed by the shutter to pass through the moisture absorbing element 3. Only dry air can be discharged outside the main body.
[0017]
As shown in FIGS. 2 and 4, the heat exchanger 2 disposed on the front side of the main body 1 (the left side in FIG. 2) has a plurality of air holes 11 through which air from the air inlet 5 passes. It consists of a hollow body. In the present invention, the shape and structure of the heat exchanger are not particularly limited, and a plurality of hollow pipes provided with radiating fins may be used as the heat exchanger.
[0018]
Further, as shown in FIGS. 2 and 5, the heat exchanger 2 is connected to a circulation path 14 that communicates with a circulation fan 12 and a heater 13 that is a heating means. Note that reference numeral 15 in FIG. 5 denotes a motor for rotating the circulation fan 12.
[0019]
Further, as shown in FIGS. 2 and 4, a drain port 16 is formed at the lower end of the heat exchanger 2, and dehumidified water condensed by the heat exchanger 2 passes through the drain port 16 below. Collected in the tank 17.
[0020]
As shown in FIG. 2, the blower fan 4 is a so-called centrifugal fan that sucks air from the front of the main body 1 and exhausts it in the radial direction of the blower fan 2. The fan 4 is driven at the center of the fan 4. The drive motor 18 is installed.
[0021]
As shown in FIGS. 2 to 3, an air inlet 5 composed of a plurality of slits is formed on the front surface of the main body 1, and the dry air absorbed through the hygroscopic element 3 is exhausted into the room on the upper surface of the main body 1. An exhaust port 19 is formed for this purpose.
[0022]
In the electric dehumidifier according to the present embodiment, as shown in FIGS. 1 to 4, indoor air is taken in through the air intake 5, passes through the heat exchanger 2, and is absorbed by the blower fan 4. 3 is blown. Moisturized air absorbs moisture when passing through the hygroscopic element 3 and becomes dry air and is exhausted outside the main body. In addition, air exhausted by the blower fan 4 without passing through the hygroscopic element 3 through the bypass hole 6 can also be obtained. Therefore, cooling of the heat exchanger 2 and drying of the laundry can be effectively performed by the large amount of air obtained by the main intake route R1 and the bypass route R2.
[0023]
The hygroscopic element 3 is rotated by the drive motor 18 to absorb indoor air, and then enters the heating region 20 facing the heater 13 and is absorbed by the hygroscopic element 3 by passing the heated air. Moisture is released. Moisturized moisture is cooled and condensed by passing through the heat exchanger 2 on the front side of the main body of FIG. 1 through the communication pipe 21 and is stored in the tank 17 through the drain 16 as dehumidified water.
[0024]
Moreover, in the dehumidifier of this Embodiment, as FIG.1 and FIG.5 shows, the bypass area | region 22 is arrange | positioned in parallel with the heating area | region 20 which has the heater 13. As shown in FIG. Therefore, a part of the air flowing through the circulation path 14 is heated by the heater 13 and used to release the moisture absorbing element 3, but other air is blown to the moisture absorbing element 3 through the bypass region 22 and the moisture absorbing element 3. Used for cooling. Therefore, when the hygroscopic element 3 shown in FIG. 1 is rotated counterclockwise, the air passing through the hygroscopic element 3 is heated by the heater 13 to release moisture adsorbed on the hygroscopic element 3 and then bypassed. Since the hygroscopic element 3 is cooled by the air passing through the region 22, the air flowing through the main intake route R1 can be effectively dehumidified.
[0025]
【The invention's effect】
According to the present invention, by forming the bypass hole, it is possible to configure an air passage that passes through the hygroscopic element and an air passage that bypasses the hygroscopic element. A large air volume can be obtained without increasing the negative pressure. Furthermore, since a large amount of air is blown from the exhaust port, the laundry can be dried quickly. Further, the air volume can be adjusted by opening and closing the bypass passage with a shutter.
