Description

【0001】
【発明の属する技術分野】
本発明は、建物の床下等の空間を換気・除湿する換気除湿装置に関するものである。
【0002】
【従来の技術】
日本古来の住居に見られるような束建てになっている場合には、家屋の床下は通気性が良く、高温多湿の気象条件下であっても耐久性の高い木造住宅とすることができるものである。しかし近年は、床下を布基礎で囲む構成としているため、わずかな換気口はあるものの床下の通気性は悪くなっている。このため床下は湿度が高く、カビや腐朽菌などが繁殖しやすく、床下を構成する木材が腐食しやすくなっている。
【0003】
このような理由で、近年、床下の通気を良くするために図7に示すような構成の床下用換気扇の使用が増えてきている。1は換気扇本体2の内部に設けている送風機で、吸気口3から床下7の淀んだ空気を吸気し排気口4から排気している。この換気扇本体2は、図8に2a・2b・2cとして示しているように、建物の北側、或いは洗面所・風呂場・台所等の水回りの床下近傍に、建物の基礎5と建物の土台6との間に数カ所設けている換気口8の一部を利用して配置している。図9はこの床下用換気扇の電気接続を示している。コントローラ9は複数個設けている換気扇本体2a・2b・2cの運転を制御する。
【0004】
以上の構成で、コントローラ9が所定の時刻の間、例えば比較的外気の湿度が低くなる午前10時頃から午後4時頃までの間、換気扇本体2を運転する。換気扇本体2が動作すると、矢印Aに示しているように南側屋外の空気が換気口8から流入する。この結果、床下7に淀んでいる多湿の空気は排気口4から屋外に排出される。この運転を繰り返すことによって、床下7の湿度は次第に低下し、床下7を構成している木材の含水率も低下して、木材の腐朽菌の活動、或いはカビの活動を抑制する。
【0005】
またコントローラ9が湿度センサを内蔵しているものでは、雨降り時等の外気の湿度が高い間は換気扇本体2の運転を停止し、外気が低湿状態になると換気扇本体2を運転する。
【0006】
【発明が解決しようとする課題】
前記従来の構成の床下用換気扇は、換気機能が充分ではないという課題を有している。つまり、単に所定の時刻の間毎日換気扇本体2を運転する構成のものは、外気の湿度が高い場合には床下7に高湿度の外気を取り込むものである。従って、逆に床下7の湿度を高めることになる。またコントローラ9が湿度センサを内蔵した構成のものは、梅雨季等の長期の高湿度状態が続く間は、運転を停止したままの状態となる。つまり、本来換気による乾燥が必要なときに運転を停止したままとなる。更に、外気の湿度が低い場合においても床下用換気扇が設置された北側の床下(洗面所等)の空気の相対湿度はそれほど低下しない。この理由は、南側の換気口から床下7に吸い込まれた屋外の空気の温度は、北側の洗面所に到達するまでに床下7に淀んでいる空気によって低下し、相対湿度を下げるまでには至らないものである。
【0007】
【課題を解決する手段】
本発明は、吸着材を用いて屋外の空気を除湿乾燥し、乾燥した空気を床下に送風すると共に、吸着材を再生する再生加熱手段の制御を屋外の空気の温度と湿度に応じたものとして、効率的な運転ができる換気除湿装置としているものである。

【0014】
【実施例】
(実施例1)
以下、本発明の第1の実施例について説明する。図1は本実施例の構成を示す断面図である。換気除湿装置の本体10(以下単に本体10と称する)内には、屋外の空気を吸気口11から吸気し送風する送風手段12と、送風手段12が送風する送風経路13を構成する風胴を設けている。送風経路13内には、シリカゲルまたはゼオライト等を使用した吸着材14と、吸着材14の上流側に設けた、吸着材14を活性化するための再生加熱手段15と、吸着材14の下流側に設けた、乾燥空気を床下16に送風する第一の排気管17と、送風手段12が送風する空気を機外に放出する第二の排気管18と、第一の排気管17と第二の排気管18とを選択的に開閉する吸着・再生経路切換弁19と、送風手段12が送風する空気を床下に送風する送風口20と、送風手段12が送風する空気を送風口20側または吸着材14側に選択的に切り換える換気・除湿切換弁21と、吸着材14を通過する前の屋外の空気の温度と湿度とを検知する検知手段25と、検知手段25の情報を受けて各部を制御する制御手段26とを配置している。制御手段26は、検知手段25の検知温度・湿度に応じて換気運転・除湿運転を実行するものである。また除湿運転の開始時または除湿運転中には、検知手段25から受けた情報に基づいて再生加熱手段15への通電時間または通電容量またはこの両方を制御しているものである。
【0015】
第一の排気管17は、送風口20と連通している。吸着・再生経路切換弁19と換気・除湿切換弁21とは、それぞれ図示していないモータ・電磁石等の駆動源と仕切り板とによって構成している。また送風手段12は、ファン・モータ及びケーシングによって構成している。また送風口20は、建物側に取り付けている換気口パネル22に、ダクト24によって連結されている。尚本体10は、北側に面した洗面所や台所等の水まわりの床下16の換気口23の近くに設置しているものである。
【0016】
次に本実施例の動作について説明する。検知手段25が検知している外気の湿度が基準値より低いときには、制御手段26は換気運転を実行する。すなわち、換気・除湿切換弁21を送風口20を開とするa側にセットし、この状態で送風手段12を運転する。従って吸気口11から吸気された低湿の屋外空気は、送風手段12によって送風口20から床下16に送風される。このため床下16に滞留している多湿の淀んだ空気は、本体10を設置している換気口23とは別の換気口から排出され、床下16の空気は低湿の屋外空気に置き換えられる。
【0017】
また検知手段25の検知湿度が基準値より高い場合には、制御手段26は除湿運転を実行する。つまり、吸気口11から吸気した多湿の屋外空気の水分を吸着材14に吸着させて乾燥した空気を床下16に送風する。このとき図2に示しているように、例えば吸着材14に屋外空気を接触させて、空気中の水分を吸着材14に吸着させて乾燥空気とする吸着モード運転から除湿運転を開始する場合には、換気・除湿切換弁21を吸着材14側を開とするb側に、吸着・再生経路切換弁19を第一の排気管17を開とするイ側にセットし、この状態で送風手段12を運転するものである。送風手段12が送風する多湿の屋外空気は、吸着材14を通過する際にその水分を奪われて乾燥し、同時に吸着材14から吸着熱を受けて温風となって、dとして示しているように第一の排気管17から送風口20へ流れ、床下16に送風される。このため床下16に滞留している多湿の淀んだ空気は、本体10を設置している換気口23とは別の換気口から排出され、床下16の空気は乾燥した低湿の空気に置き換えられる。こうして所定時間T1の吸着モード運転を行うと、吸着材14は活性が低下する。このため、所定時間T2の再生モード運転に切り換えるものである。すなわち吸着・再生経路切換弁19を第二の排気管18を開とするロ側にセットし、再生加熱手段15を所定の通電容量W1で所定時間T2の間通電するものである。このため送風手段12が送風する空気は、再生加熱手段15によって加熱され高温となって、吸着材14内を通過する。吸着材14が吸着していた水分は、この高温の空気によって吸着材14から脱離し、吸着材14は活性化されて吸着能力を回復する。吸着材14から脱離した水分を含んで多湿となった空気は、第二の排気管18から機外に放出される。こうして再生モードの運転の開始からT2の時間が経過すると、再生加熱手段15への通電を終了し、吸着・再生経路切換弁19をイ側にセットして、再び吸着モードの運転に切り換えるものである。このように吸着・再生モードの運転を繰り返すことによって、床下16の乾燥が進行する。
【0018】
このとき本実施例では、制御手段26は再生加熱手段15に対する通電時間T2あるいは通電容量W1をまたは通電時間T2と通電容量W1の両方を検知手段25の検知湿度に応じて調整するようにしているものである。つまり外気の湿度が比較的低い場合には、再生加熱手段15に対する通電は小容量・短時間で吸着材14が活性化されるが、外気の湿度が比較的高い場合には、大容量・長時間の通電が必要となるものである。従って本実施例では、特に制御手段26が除湿運転の開始時または除湿運転中に、吸着材14を通過する前の屋外空気の湿度を検知して、この検知湿度に応じて、再生加熱手段15に対する通電時間T2あるいは通電容量W1をまたは通電時間T2と通電容量W1の両方を調整するようにしているものである。従って本実施例によれば、外気の湿度の変化に対応した除湿運転が可能になり、効率の良い換気除湿装置を実現できるものである。
【0019】
尚本実施例においては、再生モードの運転時間T2と再生加熱手段15への通電時間T2とを同一の時間設定としているが、異なった時間としてもなんら支障のないものである。
【0020】
(実施例2)
次に本発明の第2の実施例について説明する。図3は、本実施例の構成を示す断面図である。本実施例では、検知手段27とを備えている。検知手段27は、本体10の内部の上部に配置しており、送風手段12が送風した空気が吸着材14を通過した後の空気の温度と湿度を検知しているものでもある。また本実施例の制御手段26は、除湿運転の開始時またはその後所定の時間行なう除湿運転中に検知手段27から受けた情報に応じて再生加熱手段15への通電時間または通電容量またはこの両方を制御するようにしているものである。
【0021】
以下、本実施例の動作について説明する。検知手段27の検知湿度が基準値より高い場合、つまり雨天時等の場合には、制御手段26は除湿運転を実行する。除湿運転中に検知手段27が検知する吸着材14を通過した後の空気の温度が例えば高くなった場合には、制御手段26は再生加熱手段15への通電時間または通電容量またはこの両方を小さくするように制御する。この制御によって、吸着材14が吸着している水分を効率的に脱離でき、効率的な運転ができる換気除湿装置としているものである。つまり外気の温度が低くなった場合は、当然、外気の絶対湿度も低くなっているものである。従って吸着材14が吸着している水分の量も少なく、活性化に必要なエネルギーの量も少なくて済むものである。この状態で仮に外気の温度が低下する以前の通電時間・通電容量を変更せずに再生加熱手段15に与え続けると、水分の脱離に使われるはずの再生加熱手段15のエネルギーの一部が送風経路13内の加熱に使用されることになるものである。送風経路13内が加熱されると、本体10内部の部品等が温度上昇して、故障の原因ともなるものである。
【0022】
この現象は、制御手段26の動作タイミングの遅れによっても発生するものであるが、本実施例では制御手段26は検知手段27の検知温度によっても動作するため、送風経路13内の温度が異常に高くなる前に適切な制御が行えるものである。また除湿運転中に検知手段27が温度が低くなった場合には、再生加熱手段15への通電時間または通電容量またはこの両方を大きくするように制御するものである。
【0023】
従って本実施例によれば、本体10の内部の温度が異常に高くなる前に、再生加熱手段15への適切な制御が可能になり、除湿運転時の屋外空気の絶対湿度の減少による本体の温度上昇等に機敏に対応でき、屋外空気の温度・湿度の変化に対応した安全で効率的な換気除湿装置を実現できるものである。
【0024】
(実施例3)
続いて本発明の第3の実施例について説明する。本実施例では、図1で説明した検知手段25と、検知手段27とを備えている。検知手段25は、本体10の下部に配置しており屋外の空気の温度と湿度とを検知している。検知手段27は、本体10の内部の上部に配置しており、送風手段12が送風した空気が吸着材14を通過した後の空気の温度と湿度を検知しているものでもある。また制御手段26は検知手段25と検知手段27の検知温度と湿度の情報を受けて、図4に示しているような制御プログラムに基づいて各部を制御しているものである。つまり検知手段25が検知する温度と湿度とに応じて、動作モードを決定しているものである。すなわち、検知手段25が検知する温度が基準値tよりも低くかつ湿度が基準値φよりも低いDの状態ときは、換気運転を実行し、検知温度が基準値tよりも低くかつ湿度が基準値φよりも高いAの状態ときと、検知温度が基準値tよりも高くかつ湿度が基準値φよりも高いBの状態ときと、検知温度が基準値tよりも高くかつ湿度が基準値φよりも低いCの状態ときとは除湿運転を実行するものである。また除湿運転中は、検知手段27が検知する温度情報によって再生加熱手段15への通電を制御しているものである。
【0025】
本実施例では、前記したように検知手段25が検知する温度と湿度とに応じて、動作モードを決定し、除湿運転中は検知手段27が検知する温度情報によって再生加熱手段15への通電を制御しているものである。従って、例えば除湿運転中に天候が急変してAの状態からDの状態へと外気の温度・湿度が大きく低下したような場合にも、正確に換気運転を実行できるものである。つまり、検知手段27のみによって制御を実行している場合には、吸着材14を通過した後の空気の温度が除湿運転での再生加熱手段15の通電によって高温となっているため、制御手段26はBの状態からCの状態に変化したと認識するものである。つまり、換気運転には切り換わらないものである。この点、本実施例では、検知手段25と検知手段27の両方を使用して、常時は検知手段25に応じて換気運転・除湿運転を切り換えるようにプログラムされているものである。このため、天候が急変してAの状態からDの状態へと外気の温度・湿度が大きく低下したような場合には、検知手段25がこの状態を正確に検知して制御手段26にフィードバックできるものである。このため、この場合にも正確に換気運転を実行できるものである。
【0026】
以上のように本実施例によれば、除湿運転の途中で外気の温度・湿度が大きく変化しても正確に換気運転・除湿運転を実行でき、また除湿運転中は検知手段27の温度情報によって再生加熱手段15への通電を制御しているため、本体10の内部の温度が異常に高くなる事態が生ずることが無く、安全で効率的な換気除湿装置を実現するものである。
【0027】
(実施例4)
続いて本発明の第4の実施例について説明する。図5は本実施例の構成を示す断面図である。本実施例で使用している吸着材14は、図1で説明した換気・除湿切換弁21の機能を兼ねているものである。すなわち、吸着材14は送風経路13内でその一端を軸に回転可能に設けているものである。
【0028】
以下本実施例の動作について説明する。検知手段25の検知湿度が低いときには、制御手段26は換気運転を実行する。すなわち、吸着・再生経路切換弁19を、第二の排気管18を閉じ第一の排気管17を開くようにイ側にセットする。また同時に、吸着材14を保持している軸を90度回転させて送風経路13を開き、この状態で送風手段12を運転するものである。従って吸気口11から吸気した低湿の屋外空気は、送風手段12によって第一の排気管17を通過して床下16に送風される。このため床下16に滞留している多湿の淀んだ空気は、本体10を設置している換気口23とは別の換気口から排出され、床下16の空気は低湿の屋外空気に置き換えられる。
【0029】
検知湿度が高い状態のときは、除湿運転を実行するものである。すなわち、吸着材14を換気運転の状態から90度逆回転させて送風経路13を閉じ、送風経路13内を流れる外気が吸着材14を通過できるようにする。その後、例えば吸着モードでの運転時には、吸着・再生経路切換弁19を第一の排気管17を開とするイ側にセットし、この状態で送風手段12を運転する。このため、送風手段12が送風する多湿の屋外空気は、吸着材14によってその水分を奪われて乾燥し、dとして示すように第一の排気管17から床下16に送風される。また再生モードでの運転時には、吸着・再生経路切換弁19を第二の排気管18を開とするロ側にセットし、再生加熱手段15を通電する。このため送風手段12が送風する空気は、再生加熱手段15によって加熱され高温となって、吸着材14と接触するものである。このため吸着材14は活性化され、吸着材14を通過した空気は、吸着材14から脱離した水分を含んで多湿となって、第二の排気管18から機外に放出される。この吸着・再生モードの運転を繰り返すことによって、床下16の除湿乾燥が進行する。
【0030】
以上のように本実施例によれば、吸着材14を送風経路13内にその一端を軸に回転可能に設けた構成として、換気・除湿切換弁の機能を兼ねることができ、送風経路13を簡単に構成できるものである。また、吸着材14は回転する際にその一端を軸にして回転するため、除湿運転において吸着材14の外周と送風経路13の内周との間の空気漏れを無くすエアータイトも容易に実現できるものである。
【0031】
またこのとき本実施例によれば、吸着材14の回転方向は、送風手段12が送風する空気の流れる方向と一致しているものである。このため、送風手段12が送風する空気は、吸着材14の表面に付着していたほこり等を吹き飛ばすようにして下方に流れていく。つまり、換気運転時に吸着材14の自動清掃も行え、簡単な構成で耐久性の高い換気除湿装置を実現しているものである。
【0032】
(実施例5)
次に本発明の第5の実施例について説明する。図6は本実施例の構成を示す断面図である。吸着材14は、図5で説明したと同様、換気・除湿切換弁21の機能を兼ねており、送風経路13に回転可能に固定した軸に設けている。また制御手段26は、検知手段25・検知手段27の検知温度・検知湿度に応じて各部を制御している。つまり、常時は検知手段25の検知情報に応じて換気運転・除湿運転の切り換えを実行し、除湿運転中は検知手段27の検知温度情報に応じて再生加熱手段15への通電時間または通電容量またはこの両方を制御しているものである。また換気運転時は、吸着・再生経路切換弁19で第二の排気管18を閉じると共に、吸着材14をその一端を軸に空気の流れる方向へ回転させて送風経路13内を開くように制御している。除湿運転時には、吸着材14をその一端を軸に逆回転させ、送風経路13内に流れる外気が吸着材14と接触するように制御しているものである。
【0033】
以上の構成とすることによって、送風経路13の構成が簡単で、また屋外空気の温度・湿度の変化による換気運転への切換えも機敏にでき、安全でさらに効率的な運転ができる換気除湿装置としているものである。また特に本実施例によれば、検知手段27自身が、換気運転時に屋外の低湿の空気の通過によって冷却されるものである。このため、例えば除湿運転から換気運転に切り換わった場合に、正しい温度検知への回復が早くできるものである。また送風経路13、再生加熱手段15等の冷却も行える。
【0034】

TECHNICAL FIELD OF THE INVENTION
The present invention relates to a ventilating and dehumidifying device for ventilating and dehumidifying a space such as under a floor of a building.
[0002]
[Prior art]
In the case of a traditional Japanese house, it can be a wooden house with good air permeability under the floor of the house and high durability even under high temperature and high humidity weather conditions. It is. However, in recent years, since the underfloor is surrounded by a cloth foundation, although there are slight ventilation holes, the air permeability under the floor is poor. For this reason, the humidity under the floor is high, mold and rot fungi easily propagate, and the wood constituting the floor is easily corroded.
[0003]
For these reasons, in recent years, the use of underfloor ventilation fans configured as shown in FIG. 7 has been increasing in order to improve the ventilation under the floor. Reference numeral 1 denotes a blower provided inside the ventilation fan main body 2, which sucks stagnant air under the floor 7 from an intake port 3 and exhausts the air from an exhaust port 4. As shown in FIG. 8 as 2a, 2b, and 2c in FIG. 8, the ventilation fan body 2 is provided on the northern side of the building or in the vicinity of the floor under the water around a washroom, a bathroom, a kitchen, or the like. 6 and a part of the ventilation port 8 provided at several places. FIG. 9 shows the electrical connection of this underfloor ventilation fan. The controller 9 controls the operation of the plurality of ventilation fan bodies 2a, 2b, 2c.
[0004]
With the above configuration, the controller 9 operates the ventilation fan main body 2 for a predetermined time, for example, from about 10:00 am to about 4:00 pm when the humidity of the outside air is relatively low. When the ventilation fan main body 2 operates, the air outside on the south side flows in from the ventilation port 8 as shown by the arrow A. As a result, the humid air stagnant under the floor 7 is discharged from the exhaust port 4 to the outside. By repeating this operation, the humidity of the underfloor 7 gradually decreases, the moisture content of the wood constituting the underfloor 7 also decreases, and the activity of rot fungi or fungi on the wood is suppressed.
[0005]
When the controller 9 has a built-in humidity sensor, the operation of the ventilation fan main body 2 is stopped while the humidity of the outside air is high such as when it rains, and the ventilation fan main body 2 is operated when the outside air is in a low humidity state.
[0006]
[Problems to be solved by the invention]
The underfloor ventilation fan having the conventional configuration has a problem that the ventilation function is not sufficient. In other words, the configuration in which the ventilation fan main body 2 is operated every day for a predetermined time simply takes in the high-humidity outside air into the underfloor 7 when the humidity of the outside air is high. Therefore, conversely, the humidity under the floor 7 is increased. When the controller 9 has a built-in humidity sensor, the operation is stopped while a long-term high humidity state such as the rainy season continues. That is, the operation remains stopped when drying by ventilation is originally required. Furthermore, even when the humidity of the outside air is low, the relative humidity of the air under the floor (such as a washroom) on the north side where the underfloor ventilation fan is installed does not decrease so much. The reason for this is that the temperature of the outdoor air sucked into the underfloor 7 from the ventilation outlet on the south side is reduced by the air stagnant under the floor 7 before reaching the washroom on the north side, and the relative humidity cannot be reduced. Not something.
[0007]

[0014]
【Example】
(Example 1)
Hereinafter, a first embodiment of the present invention will be described. FIG. 1 is a sectional view showing the configuration of the present embodiment. Inside a main body 10 (hereinafter, simply referred to as main body 10) of the ventilation and dehumidifying device, a blowing means 12 for sucking outdoor air from an air inlet 11 and blowing it, and a wind tunnel forming a blowing path 13 for blowing the blowing means 12 are provided. Provided. An adsorbent 14 made of silica gel or zeolite or the like, a regenerative heating unit 15 provided upstream of the adsorbent 14 for activating the adsorbent 14, and a downstream side of the adsorbent 14 A first exhaust pipe 17 that blows dry air below the floor 16, a second exhaust pipe 18 that discharges air blown by the blowing means 12 to the outside, a first exhaust pipe 17, and a second exhaust pipe 17. A suction / regeneration path switching valve 19 for selectively opening and closing the exhaust pipe 18 of the above, an air outlet 20 for blowing air blown by the blower means 12 below the floor, and an air blower 20 for blowing air blown by the blower means 12 A ventilation / dehumidification switching valve 21 for selectively switching to the adsorbent 14 side, a detecting means 25 for detecting the temperature and humidity of outdoor air before passing through the adsorbent 14, And control means 26 for controlling . The control means 26 executes a ventilation operation and a dehumidification operation according to the temperature and humidity detected by the detection means 25. Further, at the start of the dehumidifying operation or during the dehumidifying operation, the energizing time and / or the energizing capacity to the regenerative heating means 15 are controlled based on the information received from the detecting means 25.
[0015]
The first exhaust pipe 17 is in communication with the air outlet 20. The adsorption / regeneration path switching valve 19 and the ventilation / dehumidification switching valve 21 are each constituted by a drive source such as a motor and an electromagnet (not shown) and a partition plate. The blowing means 12 is constituted by a fan motor and a casing. The ventilation port 20 is connected to a ventilation panel 22 mounted on the building side by a duct 24. Note that the main body 10 is installed near the ventilation port 23 under the floor 16 around the water in a washroom or kitchen facing the north side.
[0016]
Next, the operation of this embodiment will be described. When the humidity of the outside air detected by the detection unit 25 is lower than the reference value, the control unit 26 executes the ventilation operation. That is, the ventilation / dehumidification switching valve 21 is set to the side a where the air outlet 20 is opened, and the air blowing means 12 is operated in this state. Therefore, the low-humidity outdoor air taken in from the air inlet 11 is blown by the air blowing means 12 from the air outlet 20 to below the floor 16. Therefore, the humid stagnant air staying under the floor 16 is exhausted from a ventilation port different from the ventilation port 23 in which the main body 10 is installed, and the air under the floor 16 is replaced with low-humidity outdoor air.
[0017]
If the detection humidity of the detection unit 25 is higher than the reference value, the control unit 26 performs a dehumidification operation. That is, the moisture of the humid outdoor air sucked from the air inlet 11 is adsorbed by the adsorbent 14 and the dried air is sent to the underfloor 16. At this time, as shown in FIG. 2, for example, when the outdoor air is brought into contact with the adsorbent 14, the moisture in the air is adsorbed by the adsorbent 14 and the dehumidifying operation is started from the adsorption mode operation in which the air is dried. Sets the ventilation / dehumidification switching valve 21 to the b side where the adsorbent 14 side is opened, and sets the adsorption / regeneration path switching valve 19 to the A side where the first exhaust pipe 17 is opened. 12 is operated. The humid outdoor air blown by the blowing means 12 is deprived of its moisture when passing through the adsorbent 14 and dried, and at the same time receives heat of adsorption from the adsorbent 14 to become hot air, which is indicated as d. As described above, the air flows from the first exhaust pipe 17 to the air outlet 20 and is blown under the floor 16. Therefore, the humid stagnant air staying under the floor 16 is exhausted from a ventilation port different from the ventilation port 23 in which the main body 10 is installed, and the air under the floor 16 is replaced with dry, low-humidity air. When the adsorption mode operation is performed for the predetermined time T1, the activity of the adsorbent 14 decreases. Therefore, the operation is switched to the regeneration mode operation for the predetermined time T2. That is, the adsorption / regeneration path switching valve 19 is set on the side where the second exhaust pipe 18 is opened, and the regeneration heating means 15 is energized with a predetermined energization capacity W1 for a predetermined time T2. For this reason, the air blown by the blowing means 12 is heated by the regeneration heating means 15 to a high temperature and passes through the adsorbent 14. The water that has been adsorbed by the adsorbent 14 is desorbed from the adsorbent 14 by the high-temperature air, and the adsorbent 14 is activated to recover the adsorption capacity. The humidified air containing the moisture desorbed from the adsorbent 14 is discharged from the second exhaust pipe 18 to the outside of the machine. When the time T2 elapses from the start of the operation in the regeneration mode, the energization of the regeneration heating means 15 is terminated, the adsorption / regeneration path switching valve 19 is set to the side A, and the operation is switched to the adsorption mode again. is there. By repeating the operation in the adsorption / regeneration mode in this manner, the drying of the underfloor 16 proceeds.
[0018]
At this time, in this embodiment, the control means 26 adjusts the power supply time T2 or the power supply capacity W1 to the regeneration heating means 15 or both the power supply time T2 and the power supply capacity W1 in accordance with the detected humidity of the detection means 25. Things. In other words, when the humidity of the outside air is relatively low, the power supply to the regeneration heating means 15 is activated with a small capacity and in a short time, but when the humidity of the outside air is relatively high, a large capacity and a long length are applied. It is necessary to energize for a long time. Therefore, in this embodiment, the control unit 26 detects the humidity of the outdoor air before passing through the adsorbent 14 at the start of the dehumidifying operation or during the dehumidifying operation. The power supply time T2 or the power supply capacity W1 or both the power supply time T2 and the power supply capacity W1 are adjusted. Therefore, according to the present embodiment, the dehumidifying operation corresponding to the change in the humidity of the outside air becomes possible, and an efficient ventilation and dehumidifying device can be realized.
[0019]
In the present embodiment, the operating time T2 in the regeneration mode and the energization time T2 to the regeneration heating means 15 are set to the same time, but different times do not cause any problem.
[0020]
(Example 2)
Next, a second embodiment of the present invention will be described. FIG. 3 is a cross-sectional view illustrating the configuration of the present embodiment. In the present embodiment, a detection unit 27 is provided. The detecting means 27 is arranged at the upper part inside the main body 10 and detects the temperature and humidity of the air after the air blown by the blowing means 12 has passed through the adsorbent 14. In addition, the control unit 26 of the present embodiment determines the energization time and / or the energization capacity to the regeneration heating unit 15 according to the information received from the detection unit 27 at the start of the dehumidification operation or during the dehumidification operation performed for a predetermined time thereafter. It is something that is controlled.
[0021]
Hereinafter, the operation of the present embodiment will be described. When the detected humidity of the detecting means 27 is higher than the reference value, that is, when it is rainy, the control means 26 executes the dehumidifying operation. If the temperature of the air after passing through the adsorbent 14 detected by the detecting means 27 during the dehumidifying operation becomes high, for example, the control means 26 reduces the energizing time and / or the energizing capacity to the regeneration heating means 15. To control. By this control, the moisture adsorbed by the adsorbent 14 can be efficiently desorbed, and the ventilating dehumidifier can be operated efficiently. That is, when the temperature of the outside air decreases, the absolute humidity of the outside air naturally decreases. Therefore, the amount of moisture adsorbed by the adsorbent 14 is small, and the amount of energy required for activation is small. In this state, if the power is continued to be supplied to the regeneration heating means 15 without changing the power supply time and the power supply capacity before the temperature of the outside air is reduced, a part of the energy of the regeneration heating means 15 which should be used for desorbing the water is obtained. This is to be used for heating the inside of the air passage 13. When the inside of the air passage 13 is heated, the temperature of parts and the like inside the main body 10 rises, which may cause a failure.
[0022]
This phenomenon also occurs due to a delay in the operation timing of the control means 26. However, in this embodiment, since the control means 26 also operates according to the temperature detected by the detection means 27, the temperature in the air passage 13 becomes abnormal. Appropriate control can be performed before it becomes high. Further, when the temperature of the detecting means 27 becomes low during the dehumidifying operation, control is performed so as to increase the energizing time and / or energizing capacity to the regeneration heating means 15.
[0023]
Therefore, according to the present embodiment, before the temperature inside the main body 10 becomes abnormally high, it is possible to appropriately control the regenerative heating means 15, and to reduce the absolute humidity of the outdoor air during the dehumidifying operation. It is possible to realize a safe and efficient ventilation and dehumidifier capable of responding to changes in temperature and humidity of outdoor air, which can respond quickly to temperature rise and the like.
[0024]
(Example 3)
Next, a third embodiment of the present invention will be described. In the present embodiment, the detection unit 25 and the detection unit 27 described with reference to FIG. 1 are provided. The detecting means 25 is disposed below the main body 10 and detects the temperature and humidity of outdoor air. The detecting means 27 is arranged at the upper part inside the main body 10 and detects the temperature and humidity of the air after the air blown by the blowing means 12 has passed through the adsorbent 14. The control means 26 receives information on the temperature and humidity detected by the detection means 25 and 27 and controls each section based on a control program as shown in FIG. That is, the operation mode is determined according to the temperature and the humidity detected by the detection unit 25. In other words, when the temperature detected by the detection means 25 is D which is lower than the reference value t and the humidity is lower than the reference value φ, the ventilation operation is performed, and the detected temperature is lower than the reference value t and the humidity is lower than the reference value t. In the state of A higher than the value φ, and in the state of B where the detection temperature is higher than the reference value t and the humidity is higher than the reference value φ, the detection temperature is higher than the reference value t and the humidity is higher than the reference value φ. When the state is lower than C, the dehumidifying operation is executed. During the dehumidifying operation, the power supply to the regenerative heating unit 15 is controlled based on the temperature information detected by the detecting unit 27.
[0025]
In the present embodiment, the operation mode is determined according to the temperature and humidity detected by the detection unit 25 as described above, and during the dehumidifying operation, the power to the regeneration heating unit 15 is supplied by the temperature information detected by the detection unit 27. It is controlling. Therefore, for example, even when the weather suddenly changes during the dehumidifying operation and the temperature and humidity of the outside air greatly decreases from the state A to the state D, the ventilation operation can be executed accurately. In other words, when the control is performed only by the detection unit 27, the temperature of the air after passing through the adsorbent 14 is high due to the energization of the regeneration heating unit 15 in the dehumidifying operation. Is recognized as having changed from the state of B to the state of C. That is, the operation is not switched to the ventilation operation. In this regard, in the present embodiment, both the detection unit 25 and the detection unit 27 are used, and the program is programmed to always switch between the ventilation operation and the dehumidification operation according to the detection unit 25. Therefore, when the weather suddenly changes and the temperature and humidity of the outside air greatly decrease from the state A to the state D, the detecting unit 25 can accurately detect this state and feed it back to the control unit 26. Things. Therefore, even in this case, the ventilation operation can be accurately performed.
[0026]
As described above, according to the present embodiment, the ventilation operation and the dehumidification operation can be accurately performed even when the temperature and humidity of the outside air greatly change during the dehumidification operation, and the temperature information of the detection unit 27 is used during the dehumidification operation. Since the power supply to the regenerative heating means 15 is controlled, a situation in which the temperature inside the main body 10 becomes abnormally high does not occur, and a safe and efficient ventilation and dehumidifying device is realized.
[0027]
(Example 4)
Next, a fourth embodiment of the present invention will be described. FIG. 5 is a sectional view showing the configuration of the present embodiment. The adsorbent 14 used in this embodiment has the function of the ventilation / dehumidification switching valve 21 described with reference to FIG. That is, the adsorbent 14 is provided so as to be rotatable around one end thereof in the air passage 13.
[0028]
Hereinafter, the operation of this embodiment will be described. When the detection humidity of the detection unit 25 is low, the control unit 26 executes the ventilation operation. That is, the adsorption / regeneration path switching valve 19 is set on the side A so that the second exhaust pipe 18 is closed and the first exhaust pipe 17 is opened. At the same time, the shaft holding the adsorbent 14 is rotated by 90 degrees to open the blowing path 13 and the blowing means 12 is operated in this state. Therefore, the low-humidity outdoor air taken in from the air inlet 11 is blown by the blowing means 12 through the first exhaust pipe 17 to the underfloor 16. Therefore, the humid stagnant air staying under the floor 16 is exhausted from a ventilation port different from the ventilation port 23 in which the main body 10 is installed, and the air under the floor 16 is replaced with low-humidity outdoor air.
[0029]
When the detected humidity is high, the dehumidifying operation is performed. That is, the adsorbent 14 is rotated 90 degrees backward from the state of the ventilation operation to close the air passage 13, so that the outside air flowing in the air passage 13 can pass through the adsorbent 14. Thereafter, for example, in the operation in the adsorption mode, the adsorption / regeneration path switching valve 19 is set to the side A where the first exhaust pipe 17 is opened, and the blowing means 12 is operated in this state. For this reason, the humid outdoor air blown by the blowing means 12 is deprived of the moisture by the adsorbent 14 and dried, and is blown from the first exhaust pipe 17 to the lower floor 16 as indicated by d. Further, during the operation in the regeneration mode, the adsorption / regeneration path switching valve 19 is set to the side where the second exhaust pipe 18 is opened, and the regeneration heating means 15 is energized. Therefore, the air blown by the blowing means 12 is heated by the regeneration heating means 15 to a high temperature, and comes into contact with the adsorbent 14. Therefore, the adsorbent 14 is activated, and the air that has passed through the adsorbent 14 becomes humid including the water desorbed from the adsorbent 14, and is discharged from the second exhaust pipe 18 to the outside of the machine. By repeating the operation in the adsorption / regeneration mode, the dehumidification and drying of the underfloor 16 proceeds.
[0030]
As described above, according to the present embodiment, the adsorbent 14 is provided in the air passage 13 so as to be rotatable around one end thereof, and can also function as a ventilation / dehumidification switching valve. It can be easily configured. In addition, since the adsorbent 14 rotates around one end when rotating, air tightness that eliminates air leakage between the outer periphery of the adsorbent 14 and the inner periphery of the air passage 13 in the dehumidifying operation can be easily realized. Things.
[0031]
At this time, according to the present embodiment, the rotation direction of the adsorbent 14 coincides with the direction in which the air blown by the blower 12 flows. Therefore, the air blown by the blowing means 12 flows downward so as to blow off dust and the like attached to the surface of the adsorbent 14. That is, the adsorbent 14 can be automatically cleaned during the ventilation operation, and a highly durable ventilation and dehumidifier with a simple configuration is realized.
[0032]
(Example 5)
Next, a fifth embodiment of the present invention will be described. FIG. 6 is a sectional view showing the configuration of the present embodiment. The adsorbent 14 also functions as the ventilation / dehumidification switching valve 21, as described with reference to FIG. 5, and is provided on a shaft rotatably fixed to the ventilation path 13. The control unit 26 controls each unit according to the detected temperature and detected humidity of the detection unit 25 and the detection unit 27. That is, the switching between the ventilation operation and the dehumidification operation is always performed in accordance with the detection information of the detection unit 25, and the energization time or the energization capacity or the energization capacity to the regeneration heating unit 15 is determined in accordance with the detection temperature information of the detection unit 27 during the dehumidification operation. This controls both. Further, during ventilation operation, the second exhaust pipe 18 is closed by the adsorption / regeneration path switching valve 19, and the adsorbent 14 is rotated around one end thereof in the direction in which air flows so as to open the inside of the ventilation path 13. are doing. At the time of the dehumidifying operation, the adsorbent 14 is reversely rotated about one end thereof to control the outside air flowing in the air blowing path 13 to contact the adsorbent 14.
[0033]
With the above configuration, the configuration of the ventilation path 13 is simple, and the switching to the ventilation operation due to the change in the temperature and humidity of the outdoor air can be performed promptly, so that the ventilation and dehumidifying device can be operated more safely and more efficiently. Is what it is. Further, according to the present embodiment, in particular, the detecting means 27 itself is cooled by the passage of outdoor low humidity air during the ventilation operation. Therefore, for example, when the operation is switched from the dehumidifying operation to the ventilation operation, it is possible to quickly recover to the correct temperature detection. In addition, the cooling of the blowing path 13, the regenerative heating means 15, and the like can be performed.
