Description

【０００１】
【発明の属する技術分野】
本発明は、主に一般家庭における室内の暖房、換気、室内もしくは室内に干した洗濯物の乾燥に使用される暖房乾燥装置の中で、特に浴室の暖房、換気、浴室もしくは浴室に干した洗濯物の乾燥を行う浴室乾燥装置の乾燥運転方法および乾燥方法に関わるものである。
【０００２】
【従来の技術】
この種の浴室乾燥装置は、既に種々考案されているが、例として特開平９−６０９４１号公報に記載されたものが知られている。以下、その構成について図２９および図３０を参照しながら説明する。
【０００３】
図２９に示すように、浴室内の天井に設置された本体１０１に浴室内の空気を換気する換気手段１０２と、浴室内の空気を循環させる循環手段１０３と、循環手段１０３により生成される循環空気を加熱する加熱手段１０４とが設けられており、換気手段１０２は、本体１０１を構成するハウジング下部に開口した吸気口１０５と、吸気口１０５より浴室の空気を吸引する換気ファン１０６と、換気ファン１０６の駆動源である換気用モータ１０７と、本体１０１内に設けた隔壁によって構成した換気風路１０８とから構成され、換気風路１０８の出口は屋外に開口した図示しないダクトに接続される排気口１０９となっている。
【０００４】
また、循環手段１０３は換気手段同様に本体１０１を構成するハウジングの下部に開口した吸気口１０５と、吸気口１０５から吸気した浴室の空気をハウジングの下部に開口している吐出口１１０から吐出することを繰り返すことによって浴室内の空気を循環させる循環ファン１１１と、循環ファン１１１の駆動源である循環用モータ１１２と、本体１０１内に設けた隔壁によって構成した循環風路１１３と、循環風路１１３の出口を構成する吐出口１１０とを備えている。
【０００５】
また、加熱手段１０４は、循環風路１１３中に設けた３個のヒーター１１４ａ、１１４ｂ、１１４ｃを備えており、換気用モータ１０７の駆動、即ち換気ファン１０６の作動、循環用モータ１１２の駆動、即ち循環ファン１１１の作動、ヒーター１１４ａ、１１４ｂ、１１４ｃの作動を各々選択的に操作することにより、浴室換気運転、浴室涼風運転、浴室暖房運転、浴室乾燥運転、浴室省エネ乾燥運転を行うものである。
【０００６】
なお本体１０１は、図３０に示しているように浴室内に配置されている。
【０００７】
以上のように構成された浴室乾燥装置の動作について説明すると、図示しないコントローラから浴室換気運転の指示が出された場合は、換気用モータ１０７を駆動して換気ファン１０６を動作させ、吸気口１０５より浴室内の空気を吸引し、換気風路１０８内を送風して排気口１０９から屋外に排気する。これにより、図３０に示しているように浴室に隣接している洗面所の乾燥した空気が浴室ドア１１５に設けられたグリル１１６から流入し、浴室内の湿った空気と洗面所の乾燥空気とが入れ替わり換気が進行することになる。
【０００８】
また、コントローラから浴室涼風運転の指示が出された場合は、換気用モータ１０７を駆動させ換気ファン１０６を動作させるとともに、循環用モータ１１２を駆動させ循環ファン１１１を動作させる。これにより、浴室内の湿った空気を浴室の外に排出し洗面所の乾燥した空気を取り込む一方、浴室の空気が浴室内に循環して浴室への涼風の供給が行われることになる。
【０００９】
また、コントローラから浴室暖房運転の指示が出された場合は、循環用モータ１１２を駆動させ循環ファン１１１を動作させるとともに、ヒーター１１４ａ、１１４ｂ、１１４ｃ全てに通電する。これにより、循環する浴室空気がヒーター１１４ａ、ヒーター１１４ｂ、ヒーター１１４ｃにより暖められ、この暖められた循環空気が浴室内を循環するので浴室内の暖房が行われることになる。
【００１０】
また、コントローラより浴室の乾燥あるいは浴室内に干されている衣類を乾燥する浴室乾燥運転の指示が出された場合は、換気用モータ１０７および循環用モータ１１２を駆動させ換気ファン１０６および循環ファン１１１を動作させるとともに、ヒーター１１４ａ、１１４ｂ、１１４ｃ全てに通電する。これにより、浴室内の湿った空気を浴室の外に排出し洗面所の乾燥した空気を取り込む一方、ヒーター１１４ａ、１１４ｂ、１１４ｃにより暖められた循環空気が浴室内を循環するので、浴室内の壁面や床面、あるいは浴室内に干されている衣類が保有している水分が蒸発し乾燥が促進することになる。
【００１１】
また、コントローラより浴室の乾燥あるいは浴室内に干されている衣類を少ない投入エネルギーで乾燥する省エネ浴室乾燥運転の指示が出された場合は、換気用モータ１０７および循環用モータ１１２を駆動させ換気ファン１０６および循環ファン１１１を動作させるとともに、ヒーター１１４ａのみに通電する。これにより、前記した通常の浴室乾燥運転と比較して乾燥時間は長くなるものの、乾燥運転で消費される電力量を少なくすることが可能となる。例えば温度２０℃、湿度６０％の雰囲気条件においては、通常の浴室乾燥運転モードではヒーター１１４ａ、１１４ｂ、１１４ｃ全てに通電で１２００Ｗ（一本当り４００Ｗ）で乾燥時間が３時間であったのに対し、省エネ浴室乾燥運転モードではヒーター１１４ａのみ通電で４００Ｗにて乾燥時間は６時間となり、乾燥運転で消費される電力量は２／３に低減された結果となった。
【００１２】
【発明が解決しようとする課題】
以上のように従来の浴室乾燥装置では、浴室の乾燥あるいは浴室内に干されている衣類を少ない投入エネルギーで乾燥する省エネ浴室乾燥運転モードを設け、乾燥運転で消費される電力量の低減を図っているが、その省エネ効果は約１／３程度であり、毎日乾燥運転を行う場合などは、まだ消費電力量が多くランニングコストが嵩み有効に使われる運転モードに成り難いという問題点があった。
【００１３】
本発明はこのような従来の課題を解決するものであり、浴室の壁面、床面あるいは浴室等に干された洗濯物の乾燥に利用される乾燥運転を、少ないエネルギー消費量で効率良く行いランニングコストを削減するとともに、従来、乾きにくいとされる浴室の隅までも十分に乾燥してカビの増殖を抑制し、掃除等の家事労働負担も減らすことができる浴室乾燥装置および乾燥運転方法を提供することを目的としている。

【発明の実施の形態】
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。なお、従来例と同一の部分については、同一番号を付し詳細な説明は省略する。
【００３９】
（実施例１）
まず本発明における浴室乾燥装置の概略構成について説明する。図１は本発明の第１の実施例における浴室乾燥装置の概略構成を示す概略断面図である。図１に示したように、この浴室乾燥装置は、浴室内の天井に設置された本体１０１に浴室内に空気を換気する換気手段１０２と、浴室内の空気を循環させる循環手段１０３と、循環手段１０３により生成される循環空気を加熱する加熱手段１０４とが設けられており、換気手段１０２は、本体１０１を構成するハウジング下部に開口した吸気口１０５と、吸気口１０５より浴室の空気を吸引する換気ファン１０６と、換気ファン１０６の駆動源である換気用直流モータ１と、本体１０１内に設けた隔壁によって構成した換気風路１０８とから構成され、換気風路１０８の出口は屋外に開口した図示しないダクトに接続される排気口１０９となっている。
【００４０】
また、循環手段１０３は換気手段同様に本体１０１を構成するハウジングの下部に開口した吸気口１０５と、吸気口１０５から吸気した浴室の空気をハウジングの下部に開口している吐出口１１０から吐出することを繰り返すことによって浴室内の空気を循環させる循環ファン１１１と、循環ファン１１１の駆動源である循環用直流モータ２と、本体１０１内に設けた隔壁によって構成した循環風路１１３と、循環風路１１３の出口を構成する吐出口１１０とを備えている。
【００４１】
また、加熱手段１０４は、循環風路１１３中に在って通電されることにより輻射熱を照射する２個の輻射ヒーター３ａ、３ｂと、この輻射ヒーター３ａ、３ｂの輻射熱を全て浴室方向に反射するための反射板４から構成され、これら輻射ヒーター３ａ、３ｂの作動と換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動を各々選択的に操作することにより、浴室換気運転、浴室涼風運転、浴室暖房運転、浴室乾燥運転を行う制御手段５を設けた構成となっている。制御手段５には換気用直流モータ１、循環用直流モータ２および輻射ヒータ３ａ、３ｂの作動を制御する制御部６の他にコントローラからの運転指示を受ける受信部７と、運転時間を積算するタイマー８とを備えている。
【００４２】
以上の構成において、次に運転動作を説明する。浴室換気運転、浴室涼風運転、浴室暖房運転の各々の運転モードにおける換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動、輻射ヒーター３ａ、３ｂの作動は従来例と同様であり、ここでは浴室乾燥運転モードにおける詳細動作を説明する。図２は本発明の第１の実施例における浴室乾燥装置の浴室乾燥運転時の動作を示す動作説明図である。図２に示すように図示しないコントローラより浴室の乾燥あるいは浴室内に干されている衣類を乾燥する浴室乾燥運転の指示が出された場合は、換気用直流モータ１を駆動させ換気ファン１０６を所定換気量が維持できるように動作させるとともに、循環用直流モータ２を駆動させ循環ファン１１１の回転数を最大に、即ち浴室内を循環する循環風量が最大となるように動作させる。更に輻射ヒーター３ａ、３ｂに通電し浴室に輻射熱を照射するとともにタイマー８をスタートさせて浴室乾燥運転時間の積算を開始する。

浴室乾燥運転中は、循環ファン１１１により循環する浴室空気は、循環風路１１３に在る輻射ヒーター３ａ、３ｂにより加熱されて循環を繰り返す。この循環により浴室空気の水蒸気分圧は低下し、この水蒸気分圧の低い浴室内の空気が循環用直流モータ２で最大回転数で回っている循環ファン１１１によって高風量で浴室内を撹拌するため、浴室の壁面や床面に付着した水分の蒸発作用が高められ浴室内の乾燥が行われる。加えて輻射ヒーター３ａ、３ｂから照射される輻射熱によって輻射熱を受けた壁面や床面に付着した水分の蒸発が更に促される。これらの動作によって蒸発した水分は水蒸気となって浴室内の空気に含まれ換気ファン１０６の運転により吸気口１０５から換気風路１０８を通って浴室外へ排出され、図示しない浴室ドアに設けられたグリルより吸気される湿度の低い空気と入れ替わって浴室内の空気の水蒸気分圧が低下していくことになる。
【００４４】
この浴室内の空気の水蒸気分圧が十分低下した段階、即ちタイマー８が予め定めた所定時間Δｔの積算を完了した段階で、輻射ヒーター３ａ、３ｂの通電のみを停止し、換気用直流モータ１、循環用直流モータ２の運転はこれまで同様に継続するのである。
【００４５】
この加熱手段１０４の出力切替ポイントは、輻射ヒーター３ａ、３ｂで熱エネルギーを与えて浴室内の空気の水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果度合と、換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスとのバランスにより決定するのが望ましく、即ち、浴室乾燥運転開始直後は、浴室内の空気温度が低いため輻射ヒーター３ａ、３ｂの熱エネルギーを与えて水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果が大きいが、乾燥運転時間が経過するに従い浴室内の空気温度が上昇し換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスが増加し、投入した熱エネルギーの乾燥に有効に使われる割合が減少するため、換気による熱エネルギーロスが増大した段階を予め算出しΔｔ時間として設定し、Δｔ時間経過時に輻射ヒーター３ａ、３ｂの動作のみを停止させるのである。
【００４６】
輻射ヒーター３ａ、３ｂが停止した後でも、浴室内の空気の水蒸気分圧は十分低下しているので、その低い水蒸気分圧の空気を循環ファン１１２により浴室内において撹拌することにより、浴室の壁面や床面に付着した水分の蒸発作用の効果は継続し浴室内の乾燥は促進することになる。
【００４７】
以上の浴室乾燥運転動作を実行することにより、従来の浴室乾燥運転、省エネ浴室乾燥運転に比較して乾燥時間は長くなるものの、乾燥運転で消費される電力量を少なくすることが可能となる。例えば温度２０℃、湿度６０％の雰囲気条件下で、換気用直流モータ１の消費電力約２５Ｗで浴室からの換気量が約９０ｍ3／ｈ、循環用直流モータ２の消費電力約１０Ｗで循環風量約３００ｍ3／ｈ、輻射ヒーター３ａ、３ｂの消費電力が約１４００Ｗ（１本当り約７００Ｗ）の機器構成において、浴室乾燥運転開始から輻射ヒーター３ａ、３ｂの通電時間Δｔを１．５時間に設定した場合に、乾燥運転終了までの時間は約８時間であり、乾燥運転で消費される電力量は、従来の省エネ乾燥運転ではランニングコストが約２５０円であったのに対し本実施例では約５０円となり、約１／５に低減が可能であることを確認した。
【００４８】
以上のように本実施例の浴室乾燥装置は、制御手段５により浴室乾燥運転の開始時は輻射ヒーター３ａ、３ｂ共に運転し最大の加熱出力を循環空気に与えて浴室内の空気の水蒸気分圧を急速に低下させて乾燥を促進し、所定時間Δｔが経過して浴室内の空気の水蒸気分圧が十分低下した後に輻射ヒーター３ａ、３ｂへの通電を停止し、高温となった浴室内の空気が換気動作により浴室外に排出させることにより生じる熱エネルギーロスを抑制しつつ、水蒸気分圧が下がった乾燥空気を循環させて水分の蒸発を促しながら、換気動作によって浴室外の乾燥空気との入替えを実行するものであるから、少ないエネルギー消費量で効率良く浴室乾燥運転を行うことができるのである。
【００４９】
また、浴室乾燥運転中は、輻射ヒーター３ａ、３ｂの通電の入り切りの同時実行のみを行うため、制御装置を複雑化することなく、簡易かつ安価な構成で効率の良い浴室乾燥運転が実行できるのである。
【００５０】
また、換気手段１０２の駆動源として換気用直流モータ１を用いているため、換気ファン１０６の駆動電力を少なく抑えるとともに、排気ダクトの抵抗に依らず常に安定した必要換気量を確保することができ、２４時間換気運転モードにも対応できるのである。
【００５１】
また、循環手段１０３の駆動源として循環用直流モータ２を用いているため、循環ファン１１１の駆動電力を少なく抑えるとともに、容易に循環ファン１１１の最大出力での運転が実現できるのである。
【００５２】
また、浴室乾燥運転時においては常に循環用直流モータ２にて循環ファン１１１を最大の回転数で運転しているので、低い水蒸気分圧の循環空気を高風量で循環させて浴室内を撹拌し、浴室の壁面や床面からの水分の蒸発作用を促進することにより、効率的に乾燥運転を行うことができるのである。
【００５３】
また、加熱手段１０４として輻射ヒーター３ａ、３ｂを用いているため、輻射ヒーター３ａ、３ｂにより加熱され低い水蒸気分圧となった循環空気の浴室内循環による水分蒸発作用に加えて、輻射ヒーター３ａ、３ｂが照射する輻射熱により浴室の壁面および床面に付着した水分の蒸発作用を促進することにより、効率的な乾燥運転を行うことができるのである。
【００５４】
なお、本実施例において循環空気を加熱する加熱手段１０４に輻射ヒーター３ａ、３ｂを用いたが、輻射ヒーターに限らず、循環空気を加熱可能なものであれば良く、例えばセラミックヒーター（ＰＴＣヒーター）、シーズヒーター、ニクロムヒーターでも同様の効果が得られ、更には内部に高温の流体が流れる熱交換器を設けても良い。高温の流体としては、温水ボイラ、ＣＯ2ヒートポンプ給湯機、コージェネ排熱等を熱源とする温水や、直膨式ヒートポンプを熱源とするＲ４１０Ａ、ＣＯ2等の冷媒を用いれば良い。
【００５５】
また、浴室乾燥運転開始から輻射ヒーター３ａ、３ｂの通電を切るまでの所定時間Δｔは予め設定するのではなく、図３に示す動作説明図のように、図示しないコントローラより設定された乾燥運転時間の所定割合としても良い。例えば所定割合を２５％に予め設定し、浴室乾燥運転の設定時間が４時間の場合には輻射ヒーターの通電時間を運転開始から４時間×２５％＝１時間、浴室乾燥運転の設定時間が８時間の場合には輻射ヒーターの通電時間を運転開始から８時間×２５％＝２時間とし、浴室乾燥運転の設定時間が１２時間の場合には輻射ヒーターの通電時間を運転開始から１２時間×２５％＝３時間として選択余地を高めることにより、様々な浴室サイズや多様な条件に見合った浴室乾燥運転が実行できるのである。
【００５６】
また、浴室乾燥運転開始から所定時間Δｔ経過時に輻射ヒーター３ａ、３ｂの通電を同時に切る制御方法としたが、浴室の広さに応じて段階的に加熱量を減少させても良い。例えば図４に示す動作説明図のように、浴室乾燥運転開始から所定時間Δｔ１経過した時に輻射ヒーター３ａのみ通電を停止し、その後所定時間Δｔ２経過した時に輻射ヒーター３ｂの通電を停止する。そして浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の駆動を停止し浴室乾燥運転を終了する制御動作としても省エネ効果が得られるのである。
【００５７】
また、浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の全ての駆動を停止する運転方法としたが、浴室乾燥運転終了後も換気用直流モータ１の運転を継続し２４時間換気運転に対応させても良い。その際には換気用直流モータ１の消費電力が低いので、省エネの２４時間換気運転を行うことができるのである。
【００５８】
（実施例２）
本実施例において、実施例１と同一部分については同一の記号を付し、詳細な説明は省略する。ここでは浴室乾燥運転時の輻射ヒーター３ａ、３ｂの通電停止判断を循環空気の温度を用いて実行する場合について述べる。
【００５９】
図５は本発明の第２の実施例における浴室乾燥装置の概略構成を示した概略断面図である。図５に示したように、循環風路１１３内に吸気口１０５より吸込まれる循環空気の温度を検出する温度センサ９を設け、制御手段５はこの温度センサ９の検出温度を取りこんで、輻射ヒーター３ａ、３ｂの作動と換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動を操作する構成となっている。
【００６０】
以上の構成において、次に運転動作を説明する。
【００６１】
浴室換気運転、浴室涼風運転、浴室暖房運転の各々の運転モードにおける換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動、輻射ヒーター３ａ、３ｂの作動は従来例と同様であり、ここでは浴室乾燥運転モードにおける詳細動作を説明する。図６は本発明の第２の実施例における浴室乾燥装置の浴室乾燥運転時の動作を示す動作説明図である。図６に示すように図示しないコントローラより浴室の乾燥あるいは浴室内に干されている衣類を乾燥する浴室乾燥運転の指示が出された場合は、換気用直流モータ１を駆動させ換気ファン１０６を所定換気量が維持できるように動作させるとともに、循環用直流モータ２を駆動させ循環ファン１１１の回転数を最大に、即ち浴室内を循環する循環風量が最大となるように動作させる。更に輻射ヒーター３ａ、３ｂに通電し浴室に輻射熱を照射するとともに温度センサ９が検出する吸気口１０５より本体１０１に吸込まれる循環空気の温度、即ち浴室温度を制御手段５に取り込む。
【００６２】
浴室乾燥運転中は、循環ファン１１１により循環する浴室空気は、循環風路１１３に在る輻射ヒーター３ａ、３ｂにより加熱されて循環を繰り返す。この循環により浴室空気の水蒸気分圧は低下し、この水蒸気分圧の低い浴室内の空気が循環用直流モータ２で最大回転数で回っている循環ファン１１１によって高風量で浴室内を撹拌するため、浴室の壁面や床面に付着した水分の蒸発作用が高められ浴室内の乾燥が行われる。加えて輻射ヒーター３ａ、３ｂから照射される輻射熱によって輻射熱を受けた壁面や床面に付着した水分の蒸発が更に促される。これらの動作によって蒸発した水分は水蒸気となって浴室内の空気に含まれ換気ファン１０６の運転により吸気口１０５から換気風路１０８を通って浴室外へ排出され、図示しない浴室ドアに設けられたグリルより吸気される湿度の低い空気と入れ替わって浴室内の空気の水蒸気分圧が低下していくことになる。
【００６３】
この浴室内の空気の水蒸気分圧が十分低下した段階は浴室内の空気温度で判断できる。即ち温度センサ９により検出される循環空気の温度、即ち浴室内の空気温度が予め定めた所定値Ｋを上回った段階で、輻射ヒーター３ａ、３ｂの通電のみを停止し、換気用直流モータ１、循環用直流モータ２の運転はこれまで同様に継続するものである。
【００６４】
この加熱手段１０４の出力切替ポイントは、輻射ヒーター３ａ、３ｂで熱エネルギーを与えて浴室内の空気の水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果度合と、換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスとのバランスにより決定するのが望ましく、即ち、浴室乾燥運転開始直後は、浴室内の空気温度が低いため輻射ヒーター３ａ、３ｂの熱エネルギーを与えて水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果が大きいが、乾燥運転時間が経過するに従い浴室内の空気温度が上昇し換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスが増加し、投入した熱エネルギーの乾燥に有効に使われる割合が減少するため、換気による熱エネルギーロスが増大した段階を浴室内の空気温度で検出し、輻射ヒーター３ａ、３ｂの動作のみを停止させるのである。
【００６５】
輻射ヒーター３ａ、３ｂが停止した後でも、浴室内の空気の水蒸気分圧は十分低下しているので、その低い水蒸気分圧の空気を循環ファン１１１により浴室内において撹拌することにより、浴室の壁面や床面に付着した水分の蒸発作用の効果は継続し浴室内の乾燥は促進することになる。
【００６６】
以上のような浴室乾燥運転動作を実行することにより、従来の浴室乾燥運転、省エネ浴室乾燥運転に比較して乾燥時間は長くなるものの、乾燥運転で消費される電力量を少なくすることが可能となる。例えば温度２０℃、湿度６０％の雰囲気条件下で、換気用直流モータ１の消費電力約２５Ｗで換気量が約９０ｍ3／ｈ、循環用直流モータ２の消費電力約１０Ｗで循環風量約３００ｍ3／ｈ、輻射ヒーター３ａ、３ｂの消費電力が約１４００Ｗ（１本当り約７００Ｗ）の機器構成において、温度センサ９の検出温度が約３８℃で輻射ヒーター３ａ、３ｂの通電を切る運転方法とした場合に、浴室乾燥運転開始から約１．５時間で輻射ヒーター３ａ、３ｂが停止し、約８時間で乾燥運転は終了した。この時の乾燥運転で消費される電力量は、従来の省エネ乾燥運転ではランニングコストが約２５０円であったのに対し本実施例では約５０円となり、約１／５に低減が可能であることを確認した。
【００６７】
以上のように本実施例の浴室乾燥装置は、制御手段５により浴室乾燥運転の開始時は輻射ヒーター３ａ、３ｂ共に運転し最大の加熱出力を循環空気に与えて温度を高め、浴室内の空気の水蒸気分圧を急速に低下させて乾燥を促進し、浴室内の空気温度が所定値Ｋまで上昇して浴室内の空気の水蒸気分圧が十分低下した後に輻射ヒーター３ａ、３ｂへの通電を停止し、高温となった浴室内の空気が換気動作により浴室外に排出させることにより生じる熱エネルギーロスを抑制しつつ、水蒸気分圧が下がった乾燥空気を循環させて水分の蒸発を促しながら、換気動作によって浴室外の乾燥空気との入替えを実行するものであるから、少ないエネルギー消費量で効率良く浴室乾燥運転を行うことができるのである。
【００６８】
なお、本実施例において循環空気を加熱する加熱手段１０４に輻射ヒーター３ａ、３ｂを用いたが、輻射ヒーターに限らず、循環空気を加熱可能なものであれば良く、例えばセラミックヒーター（ＰＴＣヒーター）、シーズヒーター、ニクロムヒーターでも同様の効果が得られ、更には内部に高温の流体が流れる熱交換器を設けても良い。高温の流体としては、温水ボイラ、ＣＯ2ヒートポンプ給湯機、コージェネ排熱等を熱源とする温水や、直膨式ヒートポンプを熱源とするＲ４１０Ａ、ＣＯ2等の冷媒を用いれば良い。
【００６９】
また、浴室乾燥運転開始から温度センサ９の検出温度が所定値Ｔ到達時に輻射ヒーター３ａ、３ｂの通電を同時に切る制御方法としたが、浴室の広さに応じて段階的に加熱量を減少させても良い。例えば図７に示す動作説明図のように、温度センサ９により検出される循環空気温度が所定値Ｋ１を上回った時に輻射ヒーター３ａのみ通電を停止し、その後所定値Ｋ２を上回った時に輻射ヒーター３ｂの通電を停止する。そして浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の駆動を停止し浴室乾燥運転を終了する制御動作としても省エネ効果が得られるのである。
【００７０】
また、浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の全ての駆動を停止する運転方法としたが、浴室乾燥運転終了後も換気用直流モータ１の運転を継続し２４時間換気運転に対応させても良い。その際には換気用直流モータ１の消費電力が低いので、省エネの２４時間換気運転を行うことができるのである。
【００７１】
（実施例３）
本実施例において、実施例１および実施例２と同一部分については同一の記号を付し、詳細な説明は省略する。ここでは浴室乾燥運転時の輻射ヒーター３ａ、３ｂの通電停止判断を循環空気の湿度を用いて実行する場合について述べる。
【００７２】
図８は本発明の第３の実施例における浴室乾燥装置の概略構成を示した概略断面図である。図８に示したように、循環風路１１３内に吸気口１０５より吸込まれる循環空気の湿度を検出する湿度センサ１０を設け、制御手段５はこの湿度センサ１０の検出湿度を取りこんで、輻射ヒーター３ａ、３ｂの作動と換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動を操作する構成となっている。
【００７３】
以上の構成において、次に運転動作を説明する。浴室換気運転、浴室涼風運転、浴室暖房運転の各々の運転モードにおける換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動、輻射ヒーター３ａ、３ｂの作動は従来例と同様であり、ここでは浴室乾燥運転モードにおける詳細動作を説明する。図９は本発明の第３の実施例における浴室乾燥装置の浴室乾燥運転時の動作を示す動作説明図である。図９に示すように図示しないコントローラより浴室の乾燥あるいは浴室内に干されている衣類を乾燥する浴室乾燥運転の指示が出された場合は、換気用直流モータ１を駆動させ換気ファン１０６を所定換気量が維持できるように動作させるとともに、循環用直流モータ２を駆動させ循環ファン１１１の回転数を最大に、即ち浴室内を循環する循環風量が最大となるように動作させる。更に輻射ヒーター３ａ、３ｂに通電し浴室に輻射熱を照射するとともに湿度センサ１０が検出する吸気口１０５より本体１０１に吸込まれる循環空気の湿度、即ち浴室湿度を制御手段５に取り込む。
【００７４】
浴室乾燥運転中は、循環ファン１１１により循環する浴室空気は、循環風路１１３に在る輻射ヒーター３ａ、３ｂにより加熱されて循環を繰り返す。この循環により浴室空気の水蒸気分圧は低下し、この水蒸気分圧の低い浴室内の空気が循環用直流モータ２で最大回転数で回っている循環ファン１１１によって高風量で浴室内を撹拌するため、浴室の壁面や床面に付着した水分の蒸発作用が高められ浴室内の乾燥が行われる。加えて輻射ヒーター３ａ、３ｂから照射される輻射熱によって輻射熱を受けた壁面や床面に付着した水分の蒸発が更に促される。これらの動作によって蒸発した水分は水蒸気となって浴室内の空気に含まれ換気ファン１０６の運転により吸気口１０５から換気風路１０８を通って浴室外へ排出され、図示しない浴室ドアに設けられたグリルより吸気される湿度の低い空気と入れ替わって浴室内の空気の水蒸気分圧が低下していくことになる。
【００７５】
この浴室内の空気の水蒸気分圧が十分低下した段階は浴室内の空気湿度でも判断できる。即ち湿度センサ１０により検出される循環空気の湿度、即ち浴室内の空気湿度が予め定めた所定値Ｈを下回った段階で、輻射ヒーター３ａ、３ｂの通電のみを停止し、換気用直流モータ１、循環用直流モータ２の運転はこれまで同様に継続するものである。
【００７６】
この加熱手段１０４の出力切替ポイントは、輻射ヒーター３ａ、３ｂで熱エネルギーを与えて浴室内の空気の水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果度合と、換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスとのバランスにより決定するのが望ましく、即ち、浴室乾燥運転開始直後は、浴室内の空気温度が低いため輻射ヒーター３ａ、３ｂの熱エネルギーを与えて水蒸気分圧を低下させることによる浴室内付着水分の蒸発作用促進効果が大きいが、乾燥運転時間が経過するに従い浴室内の空気温度が上昇し換気手段１０２による浴室内空気と浴室外空気の入れ替わりによるエネルギーロスが増加し、投入した熱エネルギーの乾燥に有効に使われる割合が減少するため、換気による熱エネルギーロスが増大した段階を浴室内の空気湿度で検出し、輻射ヒーター３ａ、３ｂの動作のみを停止させるのである。
【００７７】
輻射ヒーター３ａ、３ｂが停止した後でも、浴室内の空気の水蒸気分圧は十分低下しているので、その低い水蒸気分圧の空気を循環ファン１１１により浴室内において撹拌することにより、浴室の壁面や床面に付着した水分の蒸発作用の効果は継続し浴室内の乾燥は促進することになる。
【００７８】
以上のような浴室乾燥運転動作を実行することにより、従来の浴室乾燥運転、省エネ浴室乾燥運転に比較して乾燥時間は長くなるものの、乾燥運転で消費される電力量を少なくすることが可能となる。例えば温度２０℃、湿度６０％の雰囲気条件下で、換気用直流モータ１の消費電力約２５Ｗで換気量が約９０ｍ3／ｈ、循環用直流モータ２の消費電力約１０Ｗで循環風量約３００ｍ3／ｈ、輻射ヒーター３ａ、３ｂの消費電力が約１４００Ｗ（１本当り約７００Ｗ）の機器構成において、湿度センサ１０の検出湿度が４０％で輻射ヒーター３ａ、３ｂの通電を切る運転方法とした場合に、浴室乾燥運転開始から１．５時間で輻射ヒーター３ａ、３ｂが停止し、約８時間で乾燥運転は終了した。この時の乾燥運転で消費される電力量は、従来の省エネ乾燥運転では約２５０円であったのに対し本実施例では約５０円となり、約１／５に低減が可能であることを確認した。
【００７９】
以上のように本実施例の浴室乾燥装置は、制御手段５により浴室乾燥運転の開始時は輻射ヒーター３ａ、３ｂ共に運転し最大の加熱出力を循環空気に与えて温度を高め、浴室内の空気の水蒸気分圧を急速に低下させて乾燥を促進し、浴室内の空気湿度が所定値Ｈまで減少して浴室内の空気の水蒸気分圧が十分低下した後に輻射ヒーター３ａ、３ｂへの通電を停止し、高温となった浴室内の空気が換気動作により浴室外に排出させることにより生じる熱エネルギーロスを抑制しつつ、水蒸気分圧が下がった乾燥空気を循環させて水分の蒸発を促しながら、換気動作によって浴室外の乾燥空気との入替えを実行するものであるから、少ないエネルギー消費量で効率良く浴室乾燥運転を行うことができるのである。
【００８０】
なお、本実施例において循環空気を加熱する加熱手段１０４に輻射ヒーター３ａ、３ｂを用いたが、輻射ヒーターに限らず、循環空気を加熱可能なものであれば良く、例えばセラミックヒーター（ＰＴＣヒーター）、シーズヒーター、ニクロムヒーターでも同様の効果が得られ、更には内部に高温の流体が流れる熱交換器を設けても良い。高温の流体としては、温水ボイラ、ＣＯ2ヒートポンプ給湯機、コージェネ排熱等を熱源とする温水や、直膨式ヒートポンプを熱源とするＲ４１０Ａ、ＣＯ2等の冷媒を用いれば良い。
【００８１】
また、浴室乾燥運転開始から湿度センサ１０の検出湿度が所定値Ｈを下回った時に輻射ヒーター３ａ、３ｂの通電を同時に切る制御方法としたが、浴室の広さに応じて段階的に加熱量を減少させても良い。例えば図１０に示す動作説明図のように、湿度センサ１０により検出される循環空気湿度が所定値Ｈ１を下回った時に輻射ヒーター３ａのみ通電を停止し、その後所定値Ｈ２を下回った時に輻射ヒーター３ｂの通電を停止する。そして浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の駆動を停止し浴室乾燥運転を終了する制御動作としても省エネ効果が得られるのである。
【００８２】
また、浴室乾燥運転終了時に換気用直流モータ１および循環用直流モータ２の全ての駆動を停止する運転方法としたが、浴室乾燥運転終了後も換気用直流モータ１の運転を継続し２４時間換気運転に対応させても良い。その際には換気用直流モータ１の消費電力が低いので、省エネの２４時間換気運転を行うことができるのである。
【００８３】
（実施例４）
本実施例において、実施例１と実施例２、及び実施例３と同一部分については同一の記号を付し、詳細な説明は省略する。本実施例では、循環空気の吐出方法について述べる。図１１は実施例における浴室乾燥装置の概略構成、及び風の流れの概略図を示したものである。図１１に示したように、この浴室乾燥装置は、本体１０１を構成するハウジングの下部に開口した吸気口１０５から循環ファン１１１によって吸気した循環空気を吐出口１１０から吐出させ、前記吐出口１１０の近傍部に第１の風向制御手段１１を複数個下部が循環空気の吐出方向に対して正面に位置する浴室壁面１２の方向に向くような傾きになるように固定配置し、この第１の風向制御手段１１により吐出口１１０より吐出される循環空気の吐出方向に対して正面に位置する浴室壁面１２に集中的に循環空気を送風できる構成とする。
【００８４】
以上のように本実施例の浴室乾燥装置は、循環空気を吐出方向に対して正面に位置する浴室壁面に集中的に送風するものであるから、吐出方向に対して正面に位置する浴室壁面に付着している水滴の蒸発作用が促進され浴室壁面を短時間で乾燥することができる。
【００８５】
また、前記第１の風向制御手段１１において別の方式について説明する。図１２の上段、及び下段の図は本体１０１を構成するハウジングの下部に開口した吸気口１０５と吐出口１１０の近傍のみの断面図を示した図である。図１２の上段、及び下段の図に示すように第１の風向制御手段１１に第１の連結桟１４により複数個の第１の風向制御手段１１を連結し、その第１の連結桟１４に第１の取っ手１５を有する構成とする。
【００８６】
前記の構成において、次に第１の風向制御手段１１の動きについて説明する。図１２の上段の図に示すように第１の取っ手１５を手動にて矢印の方向に引いた場合は第１の風向制御手段１１は下部が循環空気の吐出方向に対して正面に位置する浴室壁面１２の方向に向くような傾きになるように変化し、この場合は循環空気は吐出方向に対して正面の浴室壁面１２の方向に吐出される。この場合は吐出方向に対して正面の浴室壁面１２に付着している水滴の蒸発作用が促進され短時間にて壁面乾燥がおこなえる。
【００８７】
逆に吸気口側に位置する浴室壁面１３の方向に循環空気を吐出したい場合は、図１２の下段に示すように第１の取っ手１５を手動にて矢印の方向に引き、第１の風向制御手段１１の下部が吸気口側に位置する浴室壁面１３の方向に向くような傾きになるように変化させる。この場合は吸気口側に位置する浴室壁面１３に付着している水滴の蒸発作用が促進され短時間にて浴室壁面１３の壁面乾燥がおこなえる。
【００８８】
また、図示しないが第１の風向制御手段１１を垂直になるように第１の取っ手１５を手動にて操作した場合は、循環空気は真下に吐出するようになる。この場合は真下に位置する図示しない本体１０１の真下に位置する浴室床面に向くように吐出され浴室床面の水滴の蒸発作用が促進され、浴室床面の短時間乾燥がおこなえる。
【００８９】
前記記載の動作を手動にておこなえるような構成の浴室乾燥装置であるから、所望する浴室壁面を短時間にて浴室乾燥をできるものである。もちろん、前記記載の動作を組み合わせて周期的、もしくは繰り返しておこなうことも可能であり、動作を組み合わせることによりムラなく浴室壁面の水滴の蒸発作用が促進され、さらなる効率的な浴室乾燥をできる。
【００９０】
さらに、第１の風向制御手段１１において別の方式について説明する。図１３上段、及び下段の図は本体１０１を構成するハウジングの下部に開口した吸気口１０５と吐出口１１０の近傍のみの断面図を示した図である。図１３の上段、及び下段の図に示すように第１の風向制御手段１１に第１の連結桟１４により複数個の第１の風向制御手段１１を連結し、その第１の連結桟１４に第１の駆動用モーター１６を取付、第１の駆動用モーター１６が回転することにより第１の連結桟１４が可動する構成とする。また、第１の駆動用モーター１６は第１の駆動制御手段１７によって制御される構成とする。
【００９１】
前記構成において、次に第１の風向制御手段１１の動きについて説明する。
【００９２】
図１３の上段の図に示すように第１の駆動制御手段１７によって第１の駆動用モーター１６を矢印の方向に回転させた場合、第１の風向制御手段１１は下部が循環空気の吐出方向に対して正面に位置する浴室壁面１２の方向に向くような傾きになるように変化し、この場合は循環空気は吐出方向に対して正面の浴室壁面１２の方向に吐出される。この場合は吐出方向に対して正面の浴室壁面１２に付着している水滴の蒸発作用が促進され短時間にて浴室壁面１２の壁面乾燥がおこなえる。
【００９３】
逆に吸気口側に位置する浴室壁面１３の方向に循環空気を吐出させたい場合は、図１３の下段に示すように第１の駆動制御手段１７によって第１の駆動用モーター１６を矢印の方向に回転させ、第１の風向制御手段１１の下部が吸気口側に位置する浴室壁面１３の方向に向くような傾きになるように変化し、吸気口側に位置する浴室壁面１３に付着している水滴の蒸発作用が促進され短時間にて浴室壁面１３の壁面乾燥がおこなえる。
【００９４】
また、図示しないが第１の風向制御手段１１を垂直になるように第１の駆動制御手段１７によって第１の駆動用モーター１６を駆動させ循環空気が真下に吐出するように第１の風向制御手段を制御した場合は真下に位置する図示しない本体１０１の真下に位置する浴室床面に向くように吐出され、浴室床面の水滴の蒸発作用が促進され、浴室床面の短時間乾燥がおこなえる。
【００９５】
前記記載の動作を第１の駆動制御手段１７によって第１の駆動用モーター１６を制御することにより自動的におこなえる浴室乾燥装置であるから自動的に短時間にて浴室乾燥をできるものである。もちろん、前記記載の動作を組み合わせて周期的、もしくはある一定リズム的（例えば、ゆらぎリズム）におこなうことも可能であり、動作を組み合わせることによりムラなく浴室壁面の水滴の蒸発作用が促進され、自動的におこなえるため人の手を煩わせずさらなる効率的な浴室乾燥をできる。
【００９６】
さらに、別の方式について説明する。図１４の上段、下段図は第１の風向制御手段１１の近傍のみの断面図である。図１４の上段、下段図に示すように第１の風向制御手段１１、第１の連結桟１４、及び第１の駆動用モーター１６とは別に第２の風向制御手段１８を第２の連結桟１９にて複数個連結し、第２の駆動用モーター２０が回転することにより第２の風向制御手段１８が可動する構成とする。この第２の風向制御手段１８と第１の風向制御手段１１を組み合わせ、第１の風向制御手段１１と第２の風向制御手段１８の間に吐出風通過風路２１が形成される構成とする。吐出風通過風路２１は第１の風向制御手段１１と第２の風向制御手段１８との動きにより可変される。図１４上段図に示すように第１の風向手段１１を第１の駆動用モーター１６を矢印の方向に回転させることにより第１の風向制御手段１１は下部が循環空気の吐出方向に対して正面に位置する浴室壁面１２の方向に向くような傾きとし、第２の風向手段１８を第２の駆動用モーター２０を矢印の方向に回転させることにより第２の風向制御手段１８は下部が吸気口側に位置する浴室壁面１３の方向に向くような傾きとなる。この場合は吐出風通過風路２１は小さくなり、通過する循環空気の風速は速くなり、壁面にスポット的に循環風をあてることができ、より壁面に付着した水滴の蒸発作用を促進できるため壁面乾燥を短時間でおこなえる。
【００９７】
また、図１４の下段図に示すように第２の風向手段１８を第２の駆動用モーター２０を矢印の方向に回転させることにより第２の風向制御手段１８を第１の風向制御手段１１と平行の傾きになるようにした場合は、吐出風通過風路２１は大きくなり、通過する循環空気の風量が多くなり、スポット的ではなくより広い範囲に循環空気を浴室壁面にあて浴室壁面の水滴の蒸発作用を促進し短時間での浴室乾燥がおこなえる。
【００９８】
図示しないが、前記第１の風向手段１１と第２の風向手段１８は真下に吐出させる方向にもできるため、真下の浴室床面も乾燥がおこなえる。
【００９９】
前記記載の動作を第１の風向制御手段１１と第２の風向制御手段１８を第１の駆動用モーター１６と第２の駆動用モーター２０により自動的に制御することがおこなえる浴室乾燥装置であるから、短時間にて浴室乾燥をできるものである。もちろん、前記記載の動作を組み合わせて周期的、もしくは繰り返し的におこなうことも可能であり、動作を組み合わせることによりムラなく浴室壁面の水滴の蒸発作用が促進され、自動的におこなえるため人の手を煩わせずさらなる効率的な浴室乾燥をできる。
【０１００】
前記までは、吐出される循環空気に対して正面方向の浴室壁面への制御について記載してきたが、以後は吐出される循環空気に対して平行に配置される浴室壁面への制御についても記載する。
【０１０１】
図１５は本体１０１を浴室の天井に設置し、本体１０１を構成するハウジングの下部に開口した吐出口１１０の近傍、及びユニットバスの浴槽の長手方向と平行の断面図である。図１５に示すように、本体１０１を構成するハウジングの下部に開口した吐出口１１０を設け、前記吐出口１１０に第１の風向制御手段１１が有り、この第１の風向制御手段１１を通過した風がさらにその下流側に配置する複数個の第３の風向制御手段２２ａを下部が吐出される循環空気に対して平行側に配置される浴室壁面２３ａの方向に向くように固定配置され、複数個の第３の風向制御手段２２ｂを吐出される循環空気に対して平行側に配置される浴室壁面２３ｂの方向に向くように固定配置され、吐出される循環空気が浴室壁面２３ａ、２３ｂにあたるようにワイドに循環空気が吐出される構成とする。
【０１０２】
以上のように吐出される循環空気と平行側に配置される浴室壁面に向けて吐出できるものであるからして吐出される循環空気と平行側に位置する浴室壁面に付着している水滴の蒸発作用が促進され浴室壁面を短時間で乾燥することができる。
【０１０３】
また、前記第３の風向制御手段２２ａ、２２ｂにおいて別の方式について説明する。図１６の上段、及び下段の図は本体１０１を構成するハウジングの下部に開口した吐出口１１０の近傍のみの断面図を示した図である。図１６の上段、及び下段の図に示すように第３の風向制御手段２２ａ、２２ｂに各々第３の連結桟２４ａ、２４ｂにより複数個の第３の風向制御手段２２ａ、２２ｂを連結し、その第３の連結桟２４ａ、２４ｂに各々第３の取っ手２５ａ、２５ｂを有する構成とする。
【０１０４】
前記の構成において、次に第３の風向制御手段２２ａ、２２ｂの動きについて説明する。図１６の上段の図に示すように第３の取っ手２５ａ、２５ｂを手動にて矢印の方向に引いた場合は第３の風向制御手段２２ａは下部が浴室壁面２３ａの方向に向くような傾きになるように変化する。また、第３の風向制御手段２２ｂは下部が浴室壁面２３ｂの方向に向くような傾きになるように変化する。この場合は循環空気は吐出される循環空気の方向に対して平行側の浴室壁面２３ａ、２３ｂの方向に吐出される。この場合は浴室壁面２３ａ、２３ｂに付着している水滴の蒸発作用が促進され短時間にて浴室壁面２３ａ、２３ｂの壁面乾燥がおこなえる。
【０１０５】
また図１６の下段図に示すように第３の風向制御手段２２ａを下部が浴室壁面２３ｂの方向に向くような傾きにし、さらに第３の風向手段２２ｂを第３の風向制御手段２２ａと平行な傾きとした場合は吐出する循環空気は浴室壁面２３ｂの方向に吐出され。この場合は浴室壁面２３ｂに付着している水滴の蒸発作用が促進され短時間にて壁面乾燥がおこなえる。
【０１０６】
逆に第３の風向制御手段２２ａ、２２ｂの下部を浴室壁面２３ａの方向に傾くように第３の取っ手２５ａ、２５ｂを制御した場合は、浴室壁面２３ａに循環空気があたり短時間にて浴室壁面２３ａの乾燥がおこなえる。
【０１０７】
また、図示しないが第３の風向制御手段２２ａ、２２ｂを垂直になるように第３の取っ手２５ａ、２５ｂを手動にて操作した場合は、循環空気は真下に吐出するようになる。この場合は真下に位置する図示しない浴室床面に向くように吐出され浴室床面の水滴の蒸発作用が促進され、浴室床面の短時間乾燥がおこなえる。
【０１０８】
前記記載の動作を手動にておこなえるような構成の浴室乾燥装置であるから、短時間にて所望の浴室壁面の乾燥をできるものである。もちろん、前記記載の動作を組み合わせて周期的、もしくは繰り返しておこなうことも可能であり、動作を組み合わせることによりムラなく浴室壁面の水滴の蒸発作用が促進され、さらなる効率的な浴室乾燥をできる。
【０１０９】
さらに、第３の風向制御手段２２ａ、２２ｂにおいて別の方式について説明する。図１７の上段、及び下段の図は本体１０１を構成するハウジングの下部に開口した吐出口１１０の近傍のみの断面図を示した図である。図１７の上段、及び下段の図に示すように第３の風向制御手段２２ａ、２２ｂに第３の連結桟２４ａ、２４ｂにより複数個の第３の風向制御手段２２ａ、２２ｂを連結し、その第３の連結桟２４ａ、２４ｂに第３の駆動用モーター２６ａ、２６ｂを取付、第３の駆動用モーター２６ａ、２６ｂが回転することにより第３の連結桟２４ａ、２４ｂが可動する構成とする。また、第３の駆動用モーター２６ａ、２６ｂは第２の駆動制御手段２７によって制御される構成とする。
【０１１０】
前記構成において、次に第３の風向制御手段２２ａ、２２ｂの動きについて説明する。
【０１１１】
図１７の上段の図に示すように第３の駆動制御手段２７によって第３の駆動用モーター２６ａ、２６ｂを各々矢印の方向に回転させた場合、第３の風向制御手段２６ａは下部が浴室壁面２３ａの方向に向くような傾きになるように変化し、この場合は浴室壁面２３ａの方向に吐出され、浴室壁面２３ａに付着している水滴の蒸発作用が促進され短時間にて壁面乾燥がおこなえる。また、第３の風向制御手段２６ｂは下部が浴室壁面２３ｂの方向に向くような傾きになるように変化し、この場合は浴室壁面２３ｂの方向に吐出され、浴室壁面２３ｂに付着している水滴の蒸発作用が促進され短時間にて壁面乾燥がおこなえる。よって浴室壁面２３ａ、２３ｂに循環空気を吐出させれるため、両壁面を均一に短時間で乾燥できる。
【０１１２】
また、図１７の下段に示すように第３の駆動制御手段２７によって第３の駆動用モーター２６ａ、２６ｂを矢印の方向に回転させた場合、第３の風向制御手段２２ａ、２２ｂの下部が浴室壁面２３ｂの方向に向くような傾きになるように変化し、この場合は浴室壁面２３ｂに集中的に吐出させれるため、浴室壁面２３ｂに付着している水滴の蒸発作用が促進され、短時間にて壁面乾燥がおこなえる。
【０１１３】
また、逆に図示しないが第３の風向制御手段２２ａ、２２ｂの下部を浴室壁面２３ａの方向に向くような傾きに制御させると、浴室壁面２３ａに集中的に循環空気が吐出できるようになり浴室壁面２３ａの水滴の蒸発作用が促進され、短時間で乾燥がおこなえる。
【０１１４】
前記記載の動作を第３の駆動制御手段２７によって第３の駆動用モーター２６ａ、２６ｂを制御することにより自動的におこなえる浴室乾燥装置であるから、短時間にて浴室乾燥をできるものである。もちろん、前記記載の動作を組み合わせて周期的、もしくはある一定リズム的（例えば、ゆらぎリズム）におこなうことも可能であり、動作を組み合わせることによりムラなく浴室壁面の水滴の蒸発作用が促進され、自動的におこなえるため人の手を煩わせずさらなる効率的な浴室乾燥をできる。
【０１１５】
（実施例５）
本実施例において、実施例１、２、３および４と同一部分については同一の記号を付し、詳細な説明は省略する。ここでは浴室乾燥装置に除湿機能を付加した場合の構成および浴室乾燥運転時の動作について述べる。
【０１１６】
図１８は本発明の第５の実施例における浴室乾燥装置の概略構成を示した概略断面図である。図１８に示したように、この浴室乾燥装置は、浴室内の天井に設置された本体１０１に浴室内に空気を換気する換気手段１０２と、浴室内の空気を循環させる循環手段１０３と、循環手段１０３により浴室内を循環する循環空気中の水分を除湿する除湿手段２８と、除湿手段２８により除湿した水分を凝縮させる凝縮器２９と、凝縮器２９に発生した結露水を浴室外へ排出する結露水排出手段３０とが設けられており、換気手段１０２は、本体１０１を構成するハウジング下部に開口した吸気口１０５と、吸気口１０５より浴室の空気を吸引する換気ファン１０６と、換気ファン１０６の駆動源である換気用直流モータ１と、本体１０１内に設けた隔壁によって構成した換気風路１０８とから構成され、換気風路１０８の出口は屋外に開口した図示しないダクトに接続される排気口１０９となっている。
【０１１７】
また、循環手段１０３は換気手段同様に本体１０１を構成するハウジングの下部に開口した吸気口１０５と、吸気口１０５から吸気した浴室の空気をハウジングの下部に開口している吐出口１１０から吐出することを繰り返すことによって浴室内の空気を循環させる循環ファン１１１と、循環ファン１１１の駆動源である循環用直流モータ２と、本体１０１内に設けた隔壁によって構成した循環風路１１３と、循環風路１１３の出口を構成する吐出口１１０とを備えている。
【０１１８】
また、除湿手段２８は循環風路１１３と換気風路１０８にまたがって配され、循環風路１１３に位置する吸湿部３１において循環空気より吸湿し、換気風路１０８に位置する再生部３２では加熱されて脱湿する吸着材３３と、吸湿部３１と再生部３２が連続的に入れ替わるように吸着材３３を回転させる駆動手段としての駆動モータ３４と再生部３２を加熱する加熱手段１０４としてのセラミックヒーター３５とを備えており、再生部３２において吸着材３３より脱湿した水分を凝縮器２９により凝縮させる構成となっている。
【０１１９】
また、結露水排水手段３０は凝縮器２９に発生した結露水を蒸発気化させる蒸発手段としての気化フィルター３６を備え、再生部３２において吸着材３３から脱湿した水分を吸着材３３から送り出すために吸着材３３の再生部３２に流通する再生用空気と気化フィルター３６において結露水を蒸発気化させるために気化フィルター３６を通過する蒸発用空気は共に換気ファン１０６の運転により吸気口１０５から本体１０１内に吸気される浴室の空気が用いられ、再生部３２において吸着材３３より脱湿した水分を含んだ再生用空気と気化フィルター３６において蒸発気化する結露水を含んだ蒸発用空気は共に換気ファン１０６に吸込まれ換気風路１０８を通って排気口１０９より浴室外へ排気される構成となっている。
【０１２０】
また、凝縮器２９は再生部３２において吸着材３３より脱湿した水分を含んだ高湿状態の再生用空気が流れる内部通路３７と、高湿状態の再生用空気を冷却して結露させるための冷却用空気が流れる外部通路３８を有しており、冷却用空気は循環ファン１１１の運転により吸気口１０５から本体１０１内に吸気される循環空気が用いられ、循環ファン１１１により循環する循環空気を、吸気口１０５から本体１０１に吸気し凝縮器２９の外部通路３８を通した後、吸着材３３の吸湿部３１を通過させて吐出口１１０から浴室に吐出することを繰り返して循環する構成となっている。
【０１２１】
次に吸着材３３の詳細な構成について説明する。図１９は吸着材３３の構成を示した構成説明図である。図１９に示すように、吸着材３３はセラミック繊維、ガラス繊維等の無機繊維、もしくはそれら無機繊維とパルプとを混合して抄造した平面紙３９とコルゲート加工を施した波型紙４０とを積層して巻き上げて円盤状に形成し、ゼオライト、シリカゲル、活性炭などの吸着材料を１種類以上担持したもので構成され、図中の矢印の方向に多数の小透孔４１を有していて通風が可能な構造となっている。吸着材３３が比較的湿分を多く含むときに相対的に湿度の低い空気、例えば加熱された空気が通過すると通過空気中に水分を放湿し、吸着材３３が比較的乾燥しているときに相対的に湿度の高い空気、例えば浴室内の空気が通過すると通過空気中の水分を吸湿する性質を持っている。
【０１２２】
以上の構成において、次に運転動作を説明する。浴室換気運転、浴室涼風運転、の各運転モードにおける換気用直流モータ１の駆動、即ち換気ファン１０６の作動、循環用直流モータ２の駆動、即ち循環ファン１１１の作動は従来例と同様であり、ここでは浴室乾燥運転モードにおける詳細動作を説明する。図２０は本発明の第５の実施例における浴室乾燥装置の除湿動作を伴う浴室乾燥運転時の動作を示す動作説明図である。図２０に示すように図示しないコントローラより浴室の乾燥あるいは浴室内に干されている衣類を乾燥する浴室乾燥運転の指示が出された場合は、換気用直流モータ１を駆動させ換気ファン１０６を所定換気量が維持できるように動作させるとともに、循環用直流モータ２を駆動させ循環ファン１１１の回転数を最大に、即ち浴室内を循環する循環風量が最大となるように動作させる。更に駆動モータ３４に通電し吸着材３３を回転駆動するとともに、セラミックヒーター３５に通電し吸着材３３の再生部３２を加熱して吸着材３３の再生が可能なように動作させる。
【０１２３】
循環ファン１１１の運転により浴室内を循環する循環空気は、図中実線矢印に示すように吸気口１０５より本体１０１内に入り、凝縮器２９の外部通路３８を通過する。この時、凝縮器２９の内部通路３７を流れる高湿状態の再生空気を冷却し結露させるので、結露させた水分量に相当する凝縮熱が循環空気に与えられ昇温されて吸着材３３の吸湿部３１に供給される。吸湿部３１において循環空気中の水分は吸着材３３に吸湿され低湿状態となると共に吸着熱を付与されて更に昇温され、高温低湿空気となって吐出口１１０から浴室内に吐出する。この循環を繰り返すことにより浴室内の空気は温度が上昇すると共に除湿されるので水蒸気分圧が急速に低下して浴室内の壁面や床面に付着した水分の蒸発作用が促進することになる。
【０１２４】
また、吸着材３３は、駆動モータ３４により吸湿部３１と再生部３２が連続的に入れ替わるように矢印ａ方向に回転しており、再生部３２においてセラミックヒーター３５により加熱されて脱湿再生した後、吸湿部３１において供給される循環空気より吸湿し、再び再生部３２に戻って再生するという動作を連続的に繰り返し、循環空気から常に吸湿を行うことになる。
【０１２５】
一方、換気ファン１０６の運転により発生する再生用空気は、図中破線矢印に示すように吸気口１０５より本体１０１内に入り、セラミックヒーター３５によって熱せられ高温となって吸着材３３の再生部３２に供給される。再生部３２において吸着材３３より脱湿する水分を含み高湿状態となって凝縮器２９の内部通路３７に入り、外部通路３８を通過する循環空気との熱交換を行う。この熱交換過程で再生用空気は露点温度以下に冷却された後、換気ファン１０６に吸込まれて換気風路１０８より浴室外に排気される。
【０１２６】
凝縮器２９において露点温度以下に冷却され凝縮した再生用空気中の水分は結露水となり、気化フィルター３６に集水される。この集水された水の量が除湿手段２８における除湿量となる。気化フィルター３６に集水された結露水は換気ファン１０６の運転により創出される図中一点鎖線矢印で示す蒸発用空気が気化フィルター３６を通過する際に蒸発して水蒸気となり蒸発用空気に含まれて換気ファン１０６に吸込まれ再生用空気ともに換気風路１０８より浴室外に排気される。換気ファン１０６は再生用空気と蒸発用空気を浴室内から吸気し浴室外に排気しており、この再生用空気と蒸発用空気を加算した空気量が浴室乾燥装置の換気量となる。
【０１２７】
本実施例の浴室乾燥運転における浴室内の空気の水蒸気分圧の低下度合は、加熱手段１０４で単純に循環空気を昇温する場合よりも大きくなる。即ち、加熱手段１０４で単純に昇温した場合の水蒸気分圧の低下度合は、本実施例においては吸着材３３の循環空気からの吸湿に伴い発生する吸着熱による昇温分と循環空気が除湿されることによる絶対水分量の減少分とを加算した水蒸気分圧の低下度合と同一値となり、本実施例では更に凝縮器２９において結露させた水分の凝縮熱に相当する昇温分が加算されるため、水蒸気分圧は単純な昇温動作時よりも低下することになるのである。
【０１２８】
以上のような除湿動作を伴う浴室乾燥運転により浴室内の空気の水蒸気分圧が十分低下する段階、即ち実施例１と同様に所定時間Δｔが経過した段階で、セラミックヒーター３５と駆動モータ３４の通電のみを停止し、換気用直流モータ１、循環用直流モータ２の運転を継続し、高温となった浴室内の空気が換気動作により浴室外に排出させることにより生じる熱エネルギーロスを抑制しつつ、水蒸気分圧が下がった乾燥空気を循環させて水分の蒸発を促しながら、換気動作によって浴室外の乾燥空気との入替えを行うことにより、更に効率の良い浴室乾燥運転が可能となる。
【０１２９】
以上のように本実施例の浴室乾燥装置は、吸湿部３１において循環空気中の水分を吸着材３３で吸湿して取り除き、再生部３２において吸着材３３から水分を脱湿し、脱湿した水分を換気ファン１０６で排出する動作を連続して行い浴室内の空気の水蒸気分圧を低下させるものであるから、浴室の壁面あるいは床面に付着した水分の蒸発作用を促進し効率的な乾燥運転を行うことができるのである。
【０１３０】
また、吸湿部３１において循環空気中の水分を吸着材３３で吸湿して取り除くと共に、吸湿した水分を再生部３２において吸着材３３から脱湿し、脱湿した水分を凝縮器２９において凝縮させ、その凝縮熱を循環空気に与えるものであるから、より浴室内の空気の水蒸気分圧の低下を促し浴室の壁面あるいは床面に付着した水分の蒸発作用を促進して効率的な乾燥運転を行うことができるのである。
【０１３１】
また、凝縮器２９に発生した結露水を気化フィルター３６により蒸発気化させ、気化した水分を含む水蒸気を換気ファン１０６により浴室外に排出するため、結露水の手動での排水作業を生じること無く、除湿した水分を凝縮させ、その凝縮熱を循環空気に与えて、浴室内の空気の水蒸気分圧の低下を促し、浴室の壁面あるいは床面に付着した水分の蒸発作用を促進して効率的な乾燥運転を行うことができるのである。
【０１３２】
なお、本実施例において再生部３２を加熱する加熱手段１０４にセラミックヒーター３５を用いたが、セラミックヒーター３５に限らず、再生部３２を加熱可能なものであれば良く、例えば輻射ヒーター（ハロゲンヒーター、カーボンヒーター）、シーズヒーター、ニクロムヒーターでも同様の効果が得られ、更には内部に高温の流体が流れる熱交換器を設けても良い。高温の流体としては、温水ボイラ、ＣＯ2ヒートポンプ給湯機、コージェネ排熱等を熱源とする温水や、直膨式ヒートポンプを熱源とするＲ４１０Ａ、ＣＯ2等の冷媒を用いれば良い。
【０１３３】
また、浴室乾燥運転開始からセラミックヒーター３５、駆動モータ３４の通電を切るまでの所定時間Δｔは予め設定するのではなく、コントローラにより設定された乾燥運転時間の所定割合としても良い。例えば所定割合を２５％に予め設定し、浴室乾燥運転の設定時間が４時間の場合にはセラミックヒータ３５および駆動モータ３４の通電時間を運転開始から４時間×２５％＝１時間、浴室乾燥運転の設定時間が８時間の場合にはセラミックヒータ３５および駆動モータ３４の通電時間を運転開始から８時間×２５％＝２時間とし、浴室乾燥運転の設定時間が１２時間の場合にはセラミックヒータ３５および駆動モータ３４の通電時間を運転開始から１２時間×２５％＝３時間として選択余地を高めることにより、様々な浴室サイズや多様な条件に見合った浴室乾燥運転を実行するようにしても良い。
【０１３４】
また、浴室乾燥運転開始からセラミックヒーター３５、駆動モータ３４の通電を切るまでの所定時間Δｔを予め設定するのではなく、実施例２と同様に循環空気の温度を検出する温度センサを設け、浴室乾燥運転開始から温度センサの検出温度が所定値Ｋを上回った段階でセラミックヒーター３５、駆動モータ３４の通電を切るようにしても良く、あるいは実施例３と同様に循環空気の湿度を検出する湿度センサを設け、浴室乾燥運転開始から湿度センサの検出湿度が所定値Ｈを下回った段階でセラミックヒーター３５、駆動モータ３４の通電を切るようにしても良い。
【０１３５】
また、換気ファン１０６の換気風量を再生用空気と蒸発用空気の加算値としたが、換気風量が更に必要な場合は、図２１に示すように別途吸気口１０５から直接換気ファン１０６に吸気させる風路を設けても良い。
【０１３６】
また、再生用空気を換気ファン１０６に吸込ませ浴室外に排気する構成としたが、図２２に示すように別途再生空気用ファン４２を設け、凝縮器２９の内部通路３７、セラミックヒーター３５、吸着材３３の再生部３２を循環するようにしても良い。この場合、吸湿部３１において浴室内の循環空気より吸湿した水分を再生部３２においてセラミックヒーター３５により加熱することにより脱湿し、その脱湿した水分の全量を凝縮器２９において凝縮させ結露水とすることができるため、循環空気に付与する結露水量分の凝縮熱量が増加し、より循環空気の温度を高め、浴室の壁面や床面に付着した水分の蒸発作用を更に高めることが可能となる。
【０１３７】
また、本体１０１内に吸気する循環空気の全量を吸着材３３の吸湿部３１に供給する構成としたが、騒音を抑制するため吸湿部３１の通過風速を低下させるような場合には図２３に示すように循環空気の一部を吸湿部３１に供給するように構成しても良い。
【０１３８】
また、本体１０１内に吸気する循環空気の全量を凝縮器２９の外部通路３８に供給する構成としたが、騒音を抑制するため凝縮器２９の外部通路３８の通過風速を低下させるような場合には図２４に示すように循環空気の一部を凝縮器２９の外部通路３８に供給するように構成しても良い。
【０１３９】
また、結露水排水手段３０を凝縮器２９に生じた結露水を気化フィルター３６に集水し、そこに換気ファン１０６の運転によって蒸発用空気を流通させ、蒸発気化させて水蒸気として浴室外へ排出する構成としたが、結露水の排水機能を有していれば良いのであり、例えば集水した結露水をポンプにより汲み上げ、ドレン配管を通じて排水しても良く、あるいはドレン配管を本体１０１の下方に接続し結露水をドレン配管を通して自然排水しても良い。その場合ドレン配管からの排水を浴槽内に落せばより簡易な排水が可能となる。また、自動排水機能を設けない場合には、本体１０１内に集水タンクを設け、集水タンクに相当量の結露水が溜まった時にタンクを取り出して排水しても良い。
【０１４０】
また、本実施例において浴室暖房運転を行う場合には、図２５に示すように循環用直流モータ２を駆動させ循環ファン１１１を動作させるとともに、駆動モータ３４とセラミックヒーター３５に通電し、セラミックヒーター３５により吸着材３３を加熱し、再生部３２において加熱されることにより高温となった吸着材３３を駆動モータ３４で回転させて吸湿部３１に移動させ、吸湿部３１において循環ファン１１１の運転により吸湿部３１に供給される循環空気に吸着材３３が保有する熱を付与し、循環空気は高温となって吐出口１１０より浴室内に吐出して循環する。また、吸湿部３１において熱を奪われ温度が低下した吸着材３３は再び再生部３２へと回転移動してセラミックヒータ３５により加熱される。この動作を繰り返すことにより浴室内の空気温度は上昇し暖房運転が行われることになる。あるいは、図２６に示すようにセラミックヒーター３５とは別に循環風路１１３の吐出口近傍に別途加熱手段１０４としての輻射ヒーター４３を設け、浴室暖房運転時あるいは浴室乾燥運転時にこの輻射ヒーター４３に通電して、暖房効果および乾燥効果を高めても良いのである。

[0006]
The main body 101 is arranged in the bathroom as shown in FIG.
[0007]
The operation of the bathroom drying apparatus configured as described above will be described. When an instruction for bathroom ventilation operation is issued from a controller (not shown), the ventilation fan 106 is operated by operating the ventilation motor 107 and the intake port 105 is operated. Then, the air in the bathroom is sucked, the ventilation air passage 108 is blown, and the air is exhausted from the exhaust port 109 to the outside. Thus, as shown in FIG. 30, the dry air in the bathroom adjacent to the bathroom flows in from the grill 116 provided in the bathroom door 115, and the wet air in the bathroom, the dry air in the bathroom, Will be replaced and ventilation will proceed.

Accordingly, the circulating bathroom air is heated by the heater 114a, the heater 114b, and the heater 114c, and the heated circulating air circulates in the bathroom, so that the heating in the bathroom is performed.
[0010]
  In addition, when an instruction to dry the bathroom or a bathroom drying operation for drying clothes that are dried in the bathroom is issued from the controller, the ventilation motor 107 and the circulation motor 112 are driven to drive the ventilation fan 106 and the circulation fan.111And energize all the heaters 114a, 114b, and 114c. As a result, the moist air in the bathroom is discharged outside the bathroom and the dry air in the bathroom is taken in, while the circulating air heated by the heaters 114a, 114b, 114c circulates in the bathroom. Drying is promoted by evaporating the water held by clothes that are dried on the floor or in the bathroom or in the bathroom.
[0011]

DETAILED DESCRIPTION OF THE INVENTION
Embodiments of the present invention will be described below with reference to the drawings. In addition, about the part same as a prior art example, the same number is attached | subjected and detailed description is abbreviate | omitted.
[0039]
Example 1
First, a schematic configuration of the bathroom drying apparatus in the present invention will be described. FIG. 1 is a schematic sectional view showing a schematic configuration of a bathroom drying apparatus in a first embodiment of the present invention. As shown in FIG. 1, this bathroom drying apparatus includes a ventilation means 102 for ventilating air into a bathroom, a circulation means 103 for circulating air in the bathroom, and a circulation system. Heating means 104 for heating the circulating air generated by the means 103 is provided, and the ventilation means 102 sucks bathroom air from the inlet 105 opened at the lower part of the housing constituting the main body 101 and the inlet 105.

The exhaust port 109 is connected to a duct (not shown).
[0040]
Similarly to the ventilation means, the circulation means 103 discharges the air inlet 105 opened at the lower part of the housing constituting the main body 101 and the bathroom air sucked from the air inlet 105 from the outlet 110 opened at the lower part of the housing. The circulation fan 111 that circulates the air in the bathroom by repeating this, the circulation DC motor 2 that is the drive source of the circulation fan 111, the circulation air passage 113 that is constituted by the partition provided in the main body 101, and the circulation air And a discharge port 110 constituting an outlet of the passage 113.
[0041]
  Further, the heating means 104 reflects the radiant heat of the two radiant heaters 3a and 3b that irradiate the radiant heat by being energized in the circulation air passage 113, and the radiant heats of the radiant heaters 3a and 3b. The operation of the radiation heaters 3a and 3b and the driving of the ventilation DC motor 1, that is, the operation of the ventilation fan 106, the driving of the circulation DC motor 2, that is, the operation of the circulation fan 111 are selected. Thus, the control means 5 for performing bathroom ventilation operation, bathroom cool wind operation, bathroom heating operation, and bathroom drying operation is provided. The control means 5 includes a ventilation DC motor 1, a circulation DC motor 2, and a radiation heater.3a, 3bIn addition to the control unit 6 that controls the operation, a receiving unit 7 that receives an operation instruction from the controller and a timer 8 that integrates the operation time are provided.
[0042]
  Next, the operation of the above configuration will be described. Driving of the ventilation direct current motor 1 in each operation mode of bathroom ventilation operation, bathroom cool air operation, and bathroom heating operation, that is, operation of the ventilation fan 106;DC motor for circulation2, that is, the operation of the circulation fan 111 and the operation of the radiant heaters 3 a and 3 b are the same as those in the conventional example, and the detailed operation in the bathroom drying operation mode will be described here. FIG. 2 is an operation explanatory view showing an operation during a bathroom drying operation of the bathroom drying apparatus in the first embodiment of the present invention. As shown in FIG. 2, when a controller (not shown) instructs to dry the bathroom or to dry the clothes being dried in the bathroom, the ventilation DC motor 1 is driven to set the ventilation fan 106 to a predetermined value. The operation is performed so that the ventilation amount can be maintained, and the circulation direct current motor 2 is driven so that the number of rotations of the circulation fan 111 is maximized, that is, the amount of circulation air circulating in the bathroom is maximized. Further, the radiation heaters 3a and 3b are energized to irradiate the bathroom with radiation heat, and the timer 8 is started to start accumulation of the bathroom drying operation time.
[0043]
  During the bathroom drying operation, the bathroom air circulated by the circulation fan 111 isCirculating air passageIt is heated by the radiant heaters 3a and 3b at 113 and repeats circulation. Due to this circulation, the water vapor partial pressure of the bathroom air decreases, and the air in the bathroom with a low water vapor partial pressure is stirred in the bathroom with a high air volume by the circulation fan 111 rotating at the maximum rotational speed by the DC motor 2 for circulation. The evaporation effect of the water adhering to the wall and floor of the bathroom is enhanced, and the bathroom is dried. In addition, evaporation of moisture adhering to the wall surface or floor surface that has received the radiant heat is further promoted by the radiant heat irradiated from the radiant heaters 3a and 3b. Moisture evaporated by these operations becomes water vapor and is contained in the air in the bathroom.Ventilation air passageIt is discharged out of the bathroom through 108,Installed on a bathroom door (not shown)GuriLeThe water vapor partial pressure of the air in the bathroom is lowered by replacing the low-humidity air that is sucked in.
[0044]
When the water vapor partial pressure of the air in the bathroom is sufficiently reduced, that is, when the timer 8 completes the integration of the predetermined time Δt, the energization of the radiation heaters 3a and 3b is stopped, and the ventilation direct current motor 1 The operation of the circulating DC motor 2 continues as before.
[0045]
The output switching point of the heating means 104 is based on the degree of effect of promoting the evaporation action of the moisture adhering to the bathroom by applying heat energy with the radiant heaters 3a and 3b to lower the water vapor partial pressure of the air in the bathroom, and the ventilation means 102. It is desirable to determine the balance between the energy loss due to the exchange of the air inside the bathroom and the air outside the bathroom, that is, immediately after the start of the bathroom drying operation, the air temperature in the bathroom is low, so the heat energy of the radiation heaters 3a and 3b is given. The effect of promoting the evaporation of the moisture adhering to the bathroom by lowering the water vapor partial pressure is great, but as the drying operation time elapses, the temperature of the air in the bathroom rises and the ventilation means 102 replaces the air in the bathroom and the air outside the bathroom. As energy loss increases and the rate of effective use of the input thermal energy decreases, ventilation reduces Calculated in advance the step of heat energy loss is increased and set as a Delta] t time, Delta] t time elapsed during radiant heater 3a, it is for stopping only the operation of 3b.
[0046]
  Even after the radiant heaters 3a and 3b are stopped, the water vapor partial pressure of the air in the bathroom is sufficiently reduced. Therefore, the air of the low water vapor partial pressure is stirred in the bathroom by the circulation fan 112, thereby Of water adhering to the floorofThe effect will continue and drying in the bathroom will be promoted.
[0047]
By executing the above-described bathroom drying operation, the amount of power consumed in the drying operation can be reduced, although the drying time is longer than that in the conventional bathroom drying operation and energy-saving bathroom drying operation. For example, under an atmospheric condition of a temperature of 20 ° C. and a humidity of 60%, the ventilation power from the bathroom is about 90 m with the power consumption of the ventilation DC motor 1 being about 25 W.Three/ H, power consumption of DC motor 2 for circulation is about 10W and circulation air volume is about 300mThree/ H, when the power consumption time of the radiant heaters 3a and 3b is set to 1.5 hours from the start of the bathroom drying operation in a device configuration in which the power consumption of the radiant heaters 3a and 3b is about 1400W (about 700W per one) The time to complete the drying operation is about 8 hours, and the amount of power consumed in the drying operation is about 50 yen in this embodiment, while the running cost is about 250 yen in the conventional energy-saving drying operation. It was confirmed that the reduction was possible to about 1/5.
[0048]
As described above, the bathroom drying apparatus of the present embodiment is operated by the control means 5 at the start of the bathroom drying operation with the radiation heaters 3a and 3b, giving the maximum heating output to the circulating air and the partial pressure of water vapor in the bathroom. Is rapidly reduced, and drying is promoted. After a predetermined time Δt has elapsed, the water vapor partial pressure of the air in the bathroom is sufficiently lowered, and then the energization to the radiant heaters 3a and 3b is stopped. While suppressing the heat energy loss caused by the air being exhausted outside the bathroom by the ventilation operation, circulating the dry air having a reduced water vapor partial pressure to promote moisture evaporation, Since the replacement is performed, the bathroom drying operation can be performed efficiently with a small amount of energy consumption.
[0049]
In addition, during the bathroom drying operation, only the energization of the radiant heaters 3a and 3b is performed simultaneously. Therefore, an efficient bathroom drying operation can be performed with a simple and inexpensive configuration without complicating the control device. is there.
[0050]
In addition, since the ventilation DC motor 1 is used as a drive source for the ventilation means 102, the drive power of the ventilation fan 106 can be suppressed to a low level, and a stable required ventilation amount can always be ensured regardless of the resistance of the exhaust duct. It can also support the 24-hour ventilation operation mode.
[0051]
In addition, since the circulation DC motor 2 is used as a drive source for the circulation means 103, the drive power of the circulation fan 111 can be suppressed to a low level, and the operation at the maximum output of the circulation fan 111 can be easily realized.
[0052]
In addition, during the bathroom drying operation, the circulation fan 111 is always operated at the maximum rotation speed by the DC motor 2 for circulation, so that the circulation air with a low water vapor partial pressure is circulated with a high air volume to stir the interior of the bathroom. The drying operation can be performed efficiently by promoting the evaporation of moisture from the wall and floor of the bathroom.
[0053]
In addition, since the radiation heaters 3a and 3b are used as the heating means 104, in addition to the moisture evaporation effect by circulating the circulating air heated by the radiation heaters 3a and 3b and having a low water vapor partial pressure in the bathroom, the radiation heaters 3a and 3a, Efficient drying operation can be performed by accelerating the evaporating action of the water adhering to the wall surface and floor surface of the bathroom by the radiant heat irradiated by 3b.
[0054]
In this embodiment, the radiant heaters 3a and 3b are used as the heating means 104 for heating the circulating air. However, the radiant heater is not limited to the radiant heater, and any means capable of heating the circulated air may be used. For example, a ceramic heater (PTC heater) The same effect can be obtained with a sheathed heater or a nichrome heater, and a heat exchanger through which a high-temperature fluid flows may be provided. Hot fluids include hot water boilers, CO2R410A, CO using heat pump water heaters, hot water with cogeneration exhaust heat as the heat source, and direct expansion heat pumps as the heat source2A refrigerant such as the above may be used.
[0055]
In addition, the predetermined time Δt from the start of the bathroom drying operation to the time when the radiation heaters 3a and 3b are turned off is not set in advance, but the drying operation time set by a controller (not shown) as shown in the operation explanatory diagram of FIG. It is good also as a predetermined ratio. For example, when the predetermined ratio is set to 25% in advance and the setting time of the bathroom drying operation is 4 hours, the energization time of the radiant heater is set to 4 hours × 25% = 1 hour from the start of the operation, and the setting time of the bathroom drying operation is 8 In the case of time, the energization time of the radiant heater is set to 8 hours × 25% = 2 hours from the start of operation, and when the set time of the bathroom drying operation is 12 hours, the energization time of the radiant heater is set to 12 hours × 25 from the start of operation. By increasing the choice as% = 3 hours, it is possible to execute a bathroom drying operation suitable for various bathroom sizes and various conditions.
[0056]
In addition, although the control method is such that the radiation heaters 3a and 3b are energized at the same time when the predetermined time Δt has elapsed since the start of the bathroom drying operation, the heating amount may be reduced stepwise in accordance with the size of the bathroom. For example, as shown in the operation explanatory diagram of FIG. 4, the energization of only the radiant heater 3 a is stopped when a predetermined time Δt1 has elapsed since the start of the bathroom drying operation, and then the energization of the radiant heater 3 b is stopped when the predetermined time Δt2 has elapsed. The energy saving effect can also be obtained as a control operation in which the driving of the ventilation DC motor 1 and the circulation DC motor 2 is stopped at the end of the bathroom drying operation to end the bathroom drying operation.
[0057]
Moreover, although it was set as the operation method which stops all the drive of the direct current motor 1 for ventilation and the direct current motor 2 for circulation at the end of bathroom drying operation, the operation of the direct current motor 1 for ventilation is continued after the completion of the bathroom drying operation, and ventilation is performed for 24 hours. It may correspond to driving. In that case, since the power consumption of the ventilation DC motor 1 is low, the energy-saving 24-hour ventilation operation can be performed.
[0058]

  In the present embodiment, the same parts as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Here, radiant heaters 3a, 3b during bathroom drying operationofA case where the energization stop determination is executed using the temperature of the circulating air will be described.
[0059]
  FIG. 5 is a schematic sectional view showing a schematic configuration of a bathroom drying apparatus in the second embodiment of the present invention.

[0060]
Next, the operation of the above configuration will be described.
[0061]
  Driving of the ventilation direct current motor 1 in each operation mode of bathroom ventilation operation, bathroom cool air operation, and bathroom heating operation, that is, operation of the ventilation fan 106;DC motor for circulation2, that is, the operation of the circulation fan 111 and the operation of the radiant heaters 3 a and 3 b are the same as those in the conventional example, and the detailed operation in the bathroom drying operation mode will be described here. FIG. 6 is an operation explanatory view showing the operation of the bathroom drying apparatus in the second embodiment of the present invention during the bathroom drying operation. As shown in FIG. 6, when an instruction to dry the bathroom or a bathroom drying operation for drying clothes dried in the bathroom is issued from a controller (not shown), the ventilation DC motor 1 is driven to set the ventilation fan 106 to a predetermined value. The operation is performed so that the ventilation amount can be maintained, and the circulation direct current motor 2 is driven so that the number of rotations of the circulation fan 111 is maximized, that is, the amount of circulation air circulating in the bathroom is maximized. Further, the radiant heaters 3 a and 3 b are energized to irradiate the bathroom with radiant heat, and the temperature of the circulating air sucked into the main body 101 from the intake port 105 detected by the temperature sensor 9, that is, the bathroom temperature is taken into the control means 5.
[0062]
  During the bathroom drying operation, the bathroom air circulated by the circulation fan 111 isCirculating air passageIt is heated by the radiant heaters 3a and 3b at 113 and repeats circulation. Due to this circulation, the water vapor partial pressure of the bathroom air decreases, and the air in the bathroom with a low water vapor partial pressure is stirred in the bathroom with a high air volume by the circulation fan 111 rotating at the maximum rotational speed by the DC motor 2 for circulation. The evaporation effect of the water adhering to the wall and floor of the bathroom is enhanced, and the bathroom is dried. In addition, evaporation of moisture adhering to the wall surface or floor surface that has received the radiant heat is further promoted by the radiant heat irradiated from the radiant heaters 3a and 3b. Moisture evaporated by these operations becomes water vapor and is contained in the air in the bathroom.Ventilation air passageIt is discharged out of the bathroom through 108,Installed on a bathroom door (not shown)GuriLeThe water vapor partial pressure of the air in the bathroom is lowered by replacing the low-humidity air that is sucked in.
[0063]
The stage where the water vapor partial pressure of the air in the bathroom is sufficiently lowered can be determined by the air temperature in the bathroom. That is, when the temperature of the circulating air detected by the temperature sensor 9, that is, the temperature of the air in the bathroom exceeds a predetermined value K, the energization of the radiant heaters 3a and 3b is stopped, and the ventilation direct current motor 1, The operation of the circulating DC motor 2 continues as before.
[0064]
The output switching point of the heating means 104 is based on the degree of effect of promoting the evaporation action of the moisture adhering to the bathroom by applying heat energy with the radiant heaters 3a and 3b to lower the water vapor partial pressure of the air in the bathroom, and the ventilation means 102. It is desirable to determine the balance between the energy loss due to the exchange of the air inside the bathroom and the air outside the bathroom, that is, immediately after the start of the bathroom drying operation, the air temperature in the bathroom is low, so the heat energy of the radiation heaters 3a and 3b is given. The effect of promoting the evaporation of the moisture adhering to the bathroom by lowering the water vapor partial pressure is great, but as the drying operation time elapses, the temperature of the air in the bathroom rises and the ventilation means 102 replaces the air in the bathroom and the air outside the bathroom. As energy loss increases and the rate of effective use of the input thermal energy decreases, ventilation reduces Detecting a step of heat energy loss is increased at an air temperature in the bathroom, radiant heater 3a, it is for stopping only the operation of 3b.
[0065]
  Even after the radiant heaters 3a and 3b are stopped, the water vapor partial pressure of the air in the bathroom is sufficiently lowered. Therefore, the air of the low water vapor partial pressure is stirred in the bathroom by the circulation fan 111, thereby Of water adhering to the floorofThe effect will continue and drying in the bathroom will be promoted.
[0066]
By performing the bathroom drying operation as described above, although the drying time becomes longer compared to the conventional bathroom drying operation and energy saving bathroom drying operation, it is possible to reduce the amount of power consumed in the drying operation. Become. For example, under an atmospheric condition of a temperature of 20 ° C. and a humidity of 60%, the ventilation power is about 90 m with a power consumption of about 25 W of the ventilation DC motor 1.Three/ H, power consumption of DC motor 2 for circulation is about 10W and circulation air volume is about 300mThree/ H, in a device configuration in which the power consumption of the radiant heaters 3a and 3b is about 1400 W (about 700 W per unit), the operation method of turning off the radiant heaters 3a and 3b when the temperature sensor 9 detects a temperature of about 38 ° C. In this case, the radiant heaters 3a and 3b were stopped in about 1.5 hours from the start of the bathroom drying operation, and the drying operation was completed in about 8 hours. The amount of power consumed in the drying operation at this time is about 50 yen in the present embodiment, while the running cost is about 250 yen in the conventional energy-saving drying operation, and can be reduced to about 1/5. It was confirmed.
[0067]
  As described above, in the bathroom drying apparatus of this embodiment, when the bathroom drying operation is started by the control means 5, both the radiant heaters 3a and 3b are operated and the maximum heating output is given to the circulating air to increase the temperature. Rapidly lowers the water vapor partial pressure of the air to promote drying, and the air temperature in the bathroom is a predetermined valueKAfter the water vapor partial pressure of the air in the bathroom has sufficiently decreased and the energization to the radiant heaters 3a and 3b is stopped, the heat generated by the hot air in the bathroom being discharged outside the bathroom by the ventilation operation While reducing the energy loss and circulating the dry air with reduced water vapor partial pressure to promote the evaporation of moisture, the ventilation operation replaces the dry air outside the bathroom. The bathroom drying operation can be performed efficiently.
[0068]
In this embodiment, the radiant heaters 3a and 3b are used as the heating means 104 for heating the circulating air. However, the radiant heater is not limited to the radiant heater, and any means capable of heating the circulated air may be used. For example, a ceramic heater (PTC heater) The same effect can be obtained with a sheathed heater or a nichrome heater, and a heat exchanger through which a high-temperature fluid flows may be provided. Hot fluids include hot water boilers, CO2R410A, CO using heat pump water heaters, hot water with cogeneration exhaust heat as the heat source, and direct expansion heat pumps as the heat source2A refrigerant such as the above may be used.
[0069]
In addition, when the temperature detected by the temperature sensor 9 reaches the predetermined value T from the start of the bathroom drying operation, the radiant heaters 3a and 3b are turned off simultaneously. However, the heating amount is gradually reduced according to the size of the bathroom. May be. For example, as shown in the operation explanatory diagram of FIG. 7, when the circulating air temperature detected by the temperature sensor 9 exceeds a predetermined value K1, only the radiant heater 3a is de-energized, and then when the circulating air temperature exceeds the predetermined value K2, the radiant heater 3b. Stop energizing. The energy saving effect can also be obtained as a control operation in which the driving of the ventilation DC motor 1 and the circulation DC motor 2 is stopped at the end of the bathroom drying operation to end the bathroom drying operation.
[0070]
Moreover, although it was set as the operation method which stops all the drive of the direct current motor 1 for ventilation and the direct current motor 2 for circulation at the end of bathroom drying operation, the operation of the direct current motor 1 for ventilation is continued after the completion of the bathroom drying operation, and ventilation is performed for 24 hours. It may correspond to driving. In that case, since the power consumption of the ventilation DC motor 1 is low, the energy-saving 24-hour ventilation operation can be performed.
[0071]
  (Example 3)
  In the present embodiment, the same parts as those in the first embodiment and the second embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. Here, radiant heaters 3a, 3b during bathroom drying operationofThe case where the energization stop determination is executed using the humidity of the circulating air will be described.
[0072]
  FIG. 8 is a schematic cross-sectional view showing a schematic configuration of a bathroom drying apparatus in the third embodiment of the present invention. As shown in FIG.Circulating air passageA humidity sensor 10 for detecting the humidity of the circulating air sucked from the intake port 105 is provided in 113, and the control means 5 incorporates the detected humidity of the humidity sensor 10 to operate the radiation heaters 3a and 3b and a direct current motor for ventilation. 1, that is, the operation of the ventilation fan 106, the driving of the circulation DC motor 2, that is, the operation of the circulation fan 111.
[0073]
  Next, the operation of the above configuration will be described. Driving of the ventilation direct current motor 1 in each operation mode of bathroom ventilation operation, bathroom cool air operation, and bathroom heating operation, that is, operation of the ventilation fan 106;DC motor for circulation2, that is, the operation of the circulation fan 111 and the operation of the radiant heaters 3 a and 3 b are the same as those in the conventional example, and the detailed operation in the bathroom drying operation mode will be described here. FIG. 9 is an operation explanatory view showing the operation during the bathroom drying operation of the bathroom drying apparatus in the third embodiment of the present invention. As shown in FIG. 9, when an instruction to dry the bathroom or a bathroom drying operation for drying clothes dried in the bathroom is issued from a controller (not shown), the ventilation DC motor 1 is driven to set the ventilation fan 106 to a predetermined value. The operation is performed so that the ventilation amount can be maintained, and the circulation direct current motor 2 is driven so that the number of rotations of the circulation fan 111 is maximized, that is, the amount of circulation air circulating in the bathroom is maximized. Further, the radiant heaters 3 a and 3 b are energized to irradiate the bathroom with radiant heat, and the humidity of the circulating air sucked into the main body 101 from the intake port 105 detected by the humidity sensor 10, that is, the bathroom humidity is taken into the control means 5.
[0074]
  During the bathroom drying operation, the bathroom air circulated by the circulation fan 111 isCirculating air passageIt is heated by the radiant heaters 3a and 3b at 113 and repeats circulation. Due to this circulation, the water vapor partial pressure of the bathroom air decreases, and the air in the bathroom with a low water vapor partial pressure is stirred in the bathroom with a high air volume by the circulation fan 111 rotating at the maximum rotational speed by the DC motor 2 for circulation. The evaporation effect of the water adhering to the wall and floor of the bathroom is enhanced, and the bathroom is dried. In addition, evaporation of moisture adhering to the wall surface or floor surface that has received the radiant heat is further promoted by the radiant heat irradiated from the radiant heaters 3a and 3b. Moisture evaporated by these operations becomes water vapor and is contained in the air in the bathroom.Ventilation air passageIt is discharged out of the bathroom through 108,Installed on a bathroom door (not shown)GuriLeThe water vapor partial pressure of the air in the bathroom is lowered by replacing the low-humidity air that is sucked in.
[0075]
The stage where the water vapor partial pressure of the air in the bathroom is sufficiently lowered can also be determined by the air humidity in the bathroom. That is, when the humidity of the circulating air detected by the humidity sensor 10, that is, the air humidity in the bathroom falls below a predetermined value H, only energization of the radiation heaters 3a and 3b is stopped, and the ventilation direct current motor 1, The operation of the circulating DC motor 2 continues as before.
[0076]
The output switching point of the heating means 104 is based on the degree of effect of promoting the evaporation action of the moisture adhering to the bathroom by applying heat energy with the radiant heaters 3a and 3b to lower the water vapor partial pressure of the air in the bathroom, and the ventilation means 102. It is desirable to determine the balance between the energy loss due to the exchange of the air inside the bathroom and the air outside the bathroom, that is, immediately after the start of the bathroom drying operation, the air temperature in the bathroom is low, so the heat energy of the radiation heaters 3a and 3b is given. The effect of promoting the evaporation of the moisture adhering to the bathroom by lowering the water vapor partial pressure is great, but as the drying operation time elapses, the temperature of the air in the bathroom rises and the ventilation means 102 replaces the air in the bathroom and the air outside the bathroom. As energy loss increases and the rate of effective use of the input thermal energy decreases, ventilation reduces A step of heat energy loss is increased detected air humidity in the bathroom, radiant heater 3a, it is for stopping only the operation of 3b.
[0077]
  Even after the radiant heaters 3a and 3b are stopped, the water vapor partial pressure of the air in the bathroom is sufficiently lowered.111Evaporation of water adhering to the bathroom wall and floor by stirring in the bathroomofThe effect will continue and drying in the bathroom will be promoted.
[0078]
By performing the bathroom drying operation as described above, although the drying time becomes longer compared to the conventional bathroom drying operation and energy saving bathroom drying operation, it is possible to reduce the amount of power consumed in the drying operation. Become. For example, under an atmospheric condition of a temperature of 20 ° C. and a humidity of 60%, the ventilation power is about 90 m with a power consumption of about 25 W of the ventilation DC motor 1.Three/ H, power consumption of DC motor 2 for circulation is about 10W and circulation air volume is about 300mThree/ H, when the power consumption of the radiant heaters 3a and 3b is about 1400W (about 700W per unit), and the operation method is to turn off the radiant heaters 3a and 3b when the humidity sensor 10 has a detected humidity of 40%. In addition, the radiant heaters 3a and 3b were stopped 1.5 hours after the start of the bathroom drying operation, and the drying operation was completed in about 8 hours. The amount of power consumed in the drying operation at this time was about 250 yen in the conventional energy-saving drying operation, but is about 50 yen in this embodiment, confirming that it can be reduced to about 1/5. did.
[0079]
  As described above, in the bathroom drying apparatus of this embodiment, when the bathroom drying operation is started by the control means 5, both the radiant heaters 3a and 3b are operated and the maximum heating output is given to the circulating air to increase the temperature. The water vapor partial pressure in the bathroom is rapidly reduced to promote drying andAir humidityIs a predetermined valueHUntilDecreaseThen, after the water vapor partial pressure of the air in the bathroom has sufficiently decreased, the energization to the radiant heaters 3a and 3b is stopped, and the heat energy loss caused by exhausting the heated air in the bathroom outside the bathroom by the ventilation operation This system is designed to circulate dry air with a reduced partial pressure of water vapor to promote moisture evaporation, and to replace dry air outside the bathroom with ventilation, so it can be efficiently used with low energy consumption. The bathroom can be dried.
[0080]
In this embodiment, the radiant heaters 3a and 3b are used as the heating means 104 for heating the circulating air. However, the radiant heater is not limited to the radiant heater, and any means capable of heating the circulated air may be used. For example, a ceramic heater (PTC heater) The same effect can be obtained with a sheathed heater or a nichrome heater, and a heat exchanger through which a high-temperature fluid flows may be provided. Hot fluids include hot water boilers, CO2R410A, CO using heat pump water heaters, hot water with cogeneration exhaust heat as the heat source, and direct expansion heat pumps as the heat source2A refrigerant such as the above may be used.
[0081]
Moreover, although it was set as the control method which cuts off energization of radiation heaters 3a and 3b at the same time when the humidity detected by the humidity sensor 10 falls below a predetermined value H from the start of the bathroom drying operation, the heating amount is gradually increased according to the size of the bathroom. It may be decreased. For example, as shown in the operation explanatory diagram of FIG. 10, when the circulating air humidity detected by the humidity sensor 10 falls below a predetermined value H1, only the radiant heater 3a is de-energized, and when it falls below the predetermined value H2, the radiant heater 3b. Stop energizing. The energy saving effect can also be obtained as a control operation in which the driving of the ventilation DC motor 1 and the circulation DC motor 2 is stopped at the end of the bathroom drying operation to end the bathroom drying operation.
[0082]
Moreover, although it was set as the operation method which stops all the drive of the direct current motor 1 for ventilation and the direct current motor 2 for circulation at the end of bathroom drying operation, the operation of the direct current motor 1 for ventilation is continued after the completion of the bathroom drying operation, and ventilation is performed for 24 hours. It may correspond to driving. In that case, since the power consumption of the ventilation DC motor 1 is low, the energy-saving 24-hour ventilation operation can be performed.
[0083]
(Example 4)
In the present embodiment, the same parts as those in the first embodiment, the second embodiment, and the third embodiment are denoted by the same reference numerals, and detailed description thereof is omitted. In this embodiment, a method for discharging circulating air will be described. FIG. 11: shows the schematic structure of the bathroom drying apparatus in an Example, and the schematic of the flow of a wind. As shown in FIG. 11, this bathroom drying apparatus discharges the circulating air sucked by the circulation fan 111 from the intake port 105 opened at the lower part of the housing constituting the main body 101 from the discharge port 110, and The first wind direction control means 11 is fixedly arranged in the vicinity so that the lower portions are inclined so as to be directed toward the bathroom wall surface 12 positioned in front of the circulating air discharge direction. It is set as the structure which can ventilate circulated air intensively to the bathroom wall surface 12 located in front with respect to the discharge direction of the circulating air discharged from the discharge port 110 by the control means 11.
[0084]
As described above, the bathroom drying apparatus of the present embodiment intensively blows circulating air to the bathroom wall surface located in front of the discharge direction. The evaporation effect of the attached water droplets is promoted, and the bathroom wall surface can be dried in a short time.
[0085]
  Further, another method in the first wind direction control means 11 will be described. 12 is a cross-sectional view of only the vicinity of the intake port 105 and the discharge port 110 opened in the lower part of the housing constituting the main body 101. As shown in the upper and lower diagrams of FIG.FirstA plurality of first wind direction control means 11 are connected by a connecting bar 14, and the first handle 15 is provided on the first connecting bar 14.

Next, the movement of the first wind direction control means 11 in the above configuration will be described. As shown in the upper drawing of FIG. 12, when the first handle 15 is manually pulled in the direction of the arrow, the first wind direction control means 11 is a bathroom whose lower part is located in front of the direction of discharge of the circulating air. In this case, the circulating air is discharged in the direction of the bathroom wall 12 in front of the discharge direction. In this case, the evaporation effect of water droplets adhering to the bathroom wall surface 12 in front of the discharge direction is promoted, and the wall surface can be dried in a short time.
[0087]
Conversely, when it is desired to discharge the circulating air in the direction of the bathroom wall surface 13 located on the air inlet side, the first handle 15 is manually pulled in the direction of the arrow as shown in the lower part of FIG. The lower portion of the means 11 is changed so as to be inclined toward the direction of the bathroom wall surface 13 located on the inlet side. In this case, the evaporation effect of water droplets adhering to the bathroom wall surface 13 located on the inlet side is promoted, and the wall surface of the bathroom wall surface 13 can be dried in a short time.
[0088]
Although not shown, when the first handle 15 is manually operated so that the first air direction control means 11 is vertical, the circulating air is discharged directly below. In this case, it is discharged so as to face the bathroom floor located directly below the main body 101 (not shown), and the evaporation of water droplets on the bathroom floor is promoted, so that the bathroom floor can be dried for a short time.
[0089]
Since it is a bathroom drying apparatus of the structure which can perform the operation | movement of the said description manually, the bathroom bathroom desired bathroom bathroom can be dried in a short time. Of course, it is also possible to perform the above-mentioned operations in combination with each other periodically or repeatedly, and by combining the operations, the evaporation effect of water droplets on the bathroom wall surface is promoted without unevenness, and further efficient bathroom drying can be achieved.
[0090]
Further, another method in the first wind direction control means 11 will be described. The upper and lower views of FIG. 13 are sectional views showing only the vicinity of the intake port 105 and the discharge port 110 opened at the lower portion of the housing constituting the main body 101.

The first driving motor 16 is attached, and the first connecting bar 14 is movable by rotating the first driving motor 16. The first drive motor 16 is controlled by the first drive control means 17.
[0091]
Next, the movement of the first wind direction control means 11 in the above configuration will be described.
[0092]
As shown in the upper diagram of FIG. 13, when the first drive motor 16 is rotated in the direction of the arrow by the first drive control means 17, the first wind direction control means 11 has a lower portion in the direction of discharging the circulating air. In this case, the circulating air is discharged in the direction of the bathroom wall 12 in front of the discharge direction. In this case, the evaporation effect of water droplets adhering to the front bathroom wall surface 12 with respect to the discharge direction is promoted, and the wall surface of the bathroom wall surface 12 can be dried in a short time.
[0093]
Conversely, when it is desired to discharge the circulating air in the direction of the bathroom wall surface 13 located on the inlet side, the first drive motor 16 is moved in the direction of the arrow by the first drive control means 17 as shown in the lower part of FIG. And the lower part of the first air direction control means 11 changes so as to be inclined toward the direction of the bathroom wall surface 13 located on the inlet side, and adheres to the bathroom wall surface 13 located on the inlet side. The evaporation effect of the water droplets is promoted, and the wall surface of the bathroom wall surface 13 can be dried in a short time.
[0094]
Although not shown, the first wind direction control unit 17 drives the first drive motor 16 so that the first wind direction control unit 11 is vertical so that the circulating air is discharged directly below. When the means is controlled, it is discharged so as to face the bathroom floor surface located directly below the main body 101 (not shown), and the evaporation effect of water droplets on the bathroom floor surface is promoted, so that the bathroom floor surface can be dried for a short time. .
[0095]
Since it is a bathroom drying apparatus that can automatically perform the operation described above by controlling the first drive motor 16 by the first drive control means 17, the bathroom can be automatically dried in a short time. Of course, it is also possible to perform the above-described operations in a periodic manner or in a certain rhythmic manner (for example, fluctuation rhythm). Since it can be performed manually, it is possible to dry the bathroom more efficiently without bothering people.
[0096]
Further, another method will be described. 14 is a cross-sectional view of only the vicinity of the first air direction control means 11. As shown in the upper and lower diagrams of FIG. 14, the second wind direction control means 18 is connected to the second connection bar separately from the first wind direction control means 11, the first connection bar 14, and the first drive motor 16. A plurality of units 19 are connected to each other, and the second wind direction control means 18 is movable by rotating the second driving motor 20. The second wind direction control means 18 and the first wind direction control means 11 are combined so that a discharge wind passage air passage 21 is formed between the first wind direction control means 11 and the second wind direction control means 18. . The discharge air passage 21 is varied by the movement of the first air direction control means 11 and the second air direction control means 18.

The second airflow direction control means 18 is rotated in the direction of the arrow by setting the inclination so as to face the direction of the bathroom wall surface 12 located at the bottom, and the second airflow direction control means 18 has a lower intake port. The inclination is directed toward the bathroom wall surface 13 located on the side. In this case, the discharge air passage passage 21 becomes smaller, the speed of circulating air passing therethrough becomes faster, the circulating air can be spotted on the wall surface, and the evaporation effect of water droplets adhering to the wall surface can be further promoted. Drying can be done in a short time.
[0097]
Further, as shown in the lower diagram of FIG. 14, the second wind direction control unit 18 and the first wind direction control unit 11 are rotated by rotating the second wind direction unit 18 in the direction of the arrow. In the case of parallel inclination, the discharge wind passage air passage 21 becomes large, the amount of circulating air passing therethrough increases, and the circulating air is applied to the bathroom wall surface in a wider area rather than as a spot, so that water drops on the bathroom wall surface Evaporation of the water can be promoted and bathroom drying can be performed in a short time.
[0098]
Although not shown in the drawings, the first wind direction means 11 and the second wind direction means 18 can also be discharged in the direction directly below, so that the bathroom floor just below can also be dried.
[0099]
The bathroom drying apparatus is capable of automatically controlling the first wind direction control means 11 and the second wind direction control means 18 by the first drive motor 16 and the second drive motor 20 as described above. Therefore, the bathroom can be dried in a short time. Of course, it is possible to perform the above-mentioned operations in combination with each other periodically or repeatedly, and by combining the operations, the evaporation effect of the water droplets on the bathroom wall surface is promoted without any unevenness. More efficient bathroom drying can be done without bothering you.

In this case, the circulating air is discharged in the direction of the bathroom wall surfaces 23a and 23b parallel to the direction of the discharged circulating air. In this case, the evaporation effect of water droplets adhering to the bathroom wall surfaces 23a and 23b is promoted, and the wall surfaces of the bathroom wall surfaces 23a and 23b can be dried in a short time.
[0105]
Further, as shown in the lower part of FIG. 16, the third air direction control means 22a is inclined so that the lower part faces the bathroom wall surface 23b, and the third air direction means 22b is parallel to the third air direction control means 22a. When inclined, the circulating air to be discharged is discharged in the direction of the bathroom wall surface 23b. In this case, the evaporation effect of the water droplets adhering to the bathroom wall surface 23b is promoted, and the wall surface can be dried in a short time.
[0106]
Conversely, when the third handles 25a and 25b are controlled so that the lower part of the third wind direction control means 22a and 22b is inclined toward the bathroom wall surface 23a, the circulating wall hits the bathroom wall surface 23a in a short time. 23a can be dried.
[0107]
Although not shown, when the third handles 25a and 25b are manually operated so that the third air direction control means 22a and 22b are vertical, the circulating air is discharged directly below. In this case, it is discharged so as to face a bathroom floor (not shown) located directly below, and the evaporation effect of water droplets on the bathroom floor is promoted, so that the bathroom floor can be dried for a short time.

Similarly to the ventilation means, the circulation means 103 discharges the air inlet 105 opened at the lower part of the housing constituting the main body 101 and the bathroom air sucked from the air inlet 105 from the outlet 110 opened at the lower part of the housing. The circulation fan 111 that circulates the air in the bathroom by repeating this, the circulation DC motor 2 that is the drive source of the circulation fan 111, the circulation air passage 113 that is constituted by the partition provided in the main body 101, and the circulation air And a discharge port 110 constituting an outlet of the passage 113.
[0118]
  The dehumidifying means 28 is disposed across the circulation air passage 113 and the ventilation air passage 108, absorbs moisture from the circulation air in the moisture absorption section 31 located in the circulation air passage 113, and heats in the regeneration section 32 located in the ventilation air passage 108. The adsorbent 33 dehumidified, the drive motor 34 as a driving means for rotating the adsorbent 33 so that the hygroscopic section 31 and the regeneration section 32 are continuously replaced, and the ceramic as the heating means 104 for heating the regeneration section 32. A heater 35, and a condenser that removes moisture dehydrated from the adsorbent 33 in the regeneration unit 32.29It is configured to condense.
[0119]
  Condensate drainage means30Has a vaporization filter 36 as an evaporation means for evaporating and evaporating the condensed water generated in the condenser 29, and the regeneration unit 32 of the adsorbent 33 in order to send the moisture dehumidified from the adsorbent 33 in the regeneration unit 32 from the adsorbent 33. In order to evaporate and vaporize the condensed water in the vaporizing filter 36 and the regenerating air flowing through the vaporizing filter 36,Ventilation fan 106In this operation, bathroom air sucked into the main body 101 from the intake port 105 is used, and regeneration air containing moisture dehumidified from the adsorbent 33 in the regeneration unit 32 and condensed water evaporated and evaporated in the vaporization filter 36 are used. Both the evaporation air included is a ventilation fan106And is exhausted from the exhaust port 109 to the outside of the bathroom through the ventilation air passage 108.
[0120]
Further, the condenser 29 cools the dehumidification air through the internal passage 37 through which the high-humidity regeneration air containing moisture dehumidified from the adsorbent 33 in the regeneration unit 32 is condensed. An external passage 38 through which the cooling air flows is provided. The cooling air is the circulation air that is sucked into the main body 101 from the intake port 105 by the operation of the circulation fan 111, and the circulation air circulated by the circulation fan 111 is used. Then, after the intake port 105 sucks air into the main body 101 and passes through the external passage 38 of the condenser 29, it is repeatedly circulated by passing the moisture absorbing portion 31 of the adsorbent 33 and discharging it from the discharge port 110 to the bathroom. ing.
[0121]
Next, the detailed structure of the adsorbent 33 will be described. FIG. 19 is a configuration explanatory view showing the configuration of the adsorbent 33. As shown in FIG. 19, the adsorbent 33 is formed by laminating a flat paper 39 made by mixing inorganic fibers such as ceramic fibers and glass fibers, or a mixture of these inorganic fibers and pulp, and corrugated paper 40 subjected to corrugating. It is formed by rolling up into a disk shape and is composed of one or more adsorbing materials such as zeolite, silica gel, activated carbon, etc., and has a number of small through holes 41 in the direction of the arrow in the figure, allowing ventilation. It has a simple structure. When the adsorbent 33 contains a relatively large amount of moisture, when air with relatively low humidity, for example, heated air passes, moisture is released into the passing air, and the adsorbent 33 is relatively dry. In addition, when air with relatively high humidity, for example, air in a bathroom passes, it has a property of absorbing moisture in the passing air.
[0122]
  Next, the operation of the above configuration will be described. Driving of the ventilation DC motor 1 in each operation mode of bathroom ventilation operation and bathroom cool wind operation, that is, operation of the ventilation fan 106;DC motor for circulationThe driving of 2, that is, the operation of the circulation fan 111 is the same as that of the conventional example, and here, the detailed operation in the bathroom drying operation mode will be described. FIG. 20 is an operation explanatory view showing an operation during a bathroom drying operation accompanied by a dehumidifying operation of the bathroom drying apparatus in the fifth embodiment of the present invention. As shown in FIG. 20, when an instruction for drying the bathroom or drying the clothes being dried in the bathroom is given from a controller (not shown), the ventilation DC motor 1 is driven to set the ventilation fan 106 to a predetermined value. The operation is performed so that the ventilation amount can be maintained, and the circulation direct current motor 2 is driven so that the number of rotations of the circulation fan 111 is maximized, that is, the amount of circulation air circulating in the bathroom is maximized. Further, the drive motor 34 is energized to rotate the adsorbent 33 and the ceramic heater 35 is energized to heat the regeneration unit 32 of the adsorbent 33 so that the adsorbent 33 can be regenerated.
[0123]
  Circulating air that circulates in the bathroom by the operation of the circulation fan 111 is a solid line arrow in the figure.InAs shown, the air enters the main body 101 through the intake port 105 and passes through the external passage 38 of the condenser 29. At this time, the internal passage of the condenser 2937Therefore, the condensed air corresponding to the amount of condensed moisture is given to the circulating air, the temperature is raised, and the moisture is supplied to the moisture absorbing portion 31 of the adsorbent 33. Moisture in the circulating air is absorbed by the adsorbent 33 in the hygroscopic section 31 to be in a low humidity state and is further heated by adsorption heat, and is discharged into the bathroom from the discharge port 110 as high temperature and low humidity air. By repeating this circulation, the air in the bathroom rises in temperature and is dehumidified, so that the water vapor partial pressure is rapidly lowered, and the evaporation action of moisture adhering to the wall surface and floor surface in the bathroom is promoted.
[0124]
Further, the adsorbent 33 is rotated in the direction of arrow a so that the hygroscopic portion 31 and the regenerating portion 32 are continuously switched by the drive motor 34, and after being dehumidified and regenerated by being heated by the ceramic heater 35 in the regenerating portion 32. The operation of absorbing moisture from the circulating air supplied in the moisture absorption unit 31 and returning to the regeneration unit 32 again for regeneration is continuously repeated, so that moisture is always absorbed from the circulation air.
[0125]
On the other hand, the regeneration air generated by the operation of the ventilation fan 106 enters the main body 101 through the intake port 105 as indicated by the broken line arrow in the figure, is heated by the ceramic heater 35 and becomes a high temperature, and the regeneration portion 32 of the adsorbent 33. To be supplied. In the regenerating unit 32, the moisture that dehumidifies from the adsorbent 33 enters a high humidity state, enters the internal passage 37 of the condenser 29, and performs heat exchange with the circulating air that passes through the external passage 38. In this heat exchange process, the regeneration air is cooled below the dew point temperature, and then is sucked into the ventilation fan 106 and exhausted outside the bathroom through the ventilation air passage 108.
[0126]
The water in the regeneration air that has been cooled and condensed below the dew point temperature in the condenser 29 becomes condensed water and is collected in the vaporization filter 36. The amount of the collected water becomes the dehumidifying amount in the dehumidifying means 28. The condensed water collected in the vaporizing filter 36 is evaporated when the evaporating air shown by the one-dot chain line arrow in the figure created by the operation of the ventilation fan 106 passes through the vaporizing filter 36 to become water vapor and is included in the evaporating air. Then, the air is sucked into the ventilation fan 106 and the air for regeneration is exhausted from the ventilation air passage 108 to the outside of the bathroom. The ventilation fan 106 sucks the regeneration air and the evaporation air from the bathroom and exhausts the air outside the bathroom, and the amount of air obtained by adding the regeneration air and the evaporation air becomes the ventilation amount of the bathroom drying apparatus.
[0127]
The degree of decrease in the water vapor partial pressure of the air in the bathroom in the bathroom drying operation of the present embodiment is larger than that when the heating means 104 simply raises the temperature of the circulating air. That is, the degree of decrease in the water vapor partial pressure when the temperature is simply raised by the heating means 104 is determined in the present embodiment when the temperature rise due to the adsorption heat generated by moisture absorption from the circulating air of the adsorbent 33 and the circulating air are dehumidified. In this embodiment, a temperature increase corresponding to the heat of condensation of moisture condensed in the condenser 29 is further added. Therefore, the water vapor partial pressure is lower than that during a simple temperature raising operation.
[0128]
When the steam partial pressure of the air in the bathroom is sufficiently lowered by the bathroom drying operation with the dehumidifying operation as described above, that is, when the predetermined time Δt has passed as in the first embodiment, the ceramic heater 35 and the drive motor 34 While only energizing is stopped, the operation of the ventilation DC motor 1 and the circulation DC motor 2 is continued, and the heat energy loss caused by exhausting the heated air in the bathroom outside the bathroom by the ventilation operation is suppressed. Further, a more efficient bathroom drying operation can be performed by replacing the drying air outside the bathroom with a ventilation operation while circulating the drying air having a reduced water vapor partial pressure to promote evaporation of moisture.
[0129]
As described above, in the bathroom drying apparatus of the present embodiment, moisture in the circulating air is removed by absorbing the moisture in the moisture absorbing section 31 with the adsorbent 33, and moisture is dehumidified from the adsorbent 33 in the regenerating section 32, and the moisture is dehumidified. The exhaust fan 106 is continuously discharged to reduce the water vapor partial pressure of the air in the bathroom, so that the evaporation action of water adhering to the wall surface or floor surface of the bathroom is promoted and efficient drying operation is performed. Can be done.
[0130]
In addition, moisture in the circulating air is removed by the adsorbent 33 in the hygroscopic section 31, and the moisture absorbed is dehumidified from the adsorbent 33 in the regeneration section 32, and the dehumidified water is condensed in the condenser 29. Since the heat of condensation is given to the circulating air, it is possible to further reduce the water vapor partial pressure of the air in the bathroom and promote the evaporation action of moisture adhering to the wall surface or floor surface of the bathroom for efficient drying operation. It can be done.
[0131]
In addition, the condensed water generated in the condenser 29 is evaporated and evaporated by the vaporizing filter 36, and the water vapor containing the evaporated water is discharged outside the bathroom by the ventilation fan 106. Condensed dehumidified moisture and give the heat of condensation to the circulating air to promote a decrease in the water vapor partial pressure of the air in the bathroom, and promote the evaporation of moisture adhering to the wall or floor of the bathroom. A drying operation can be performed.
[0132]
In this embodiment, the ceramic heater 35 is used as the heating means 104 for heating the regenerating unit 32. However, the heating unit 104 is not limited to the ceramic heater 35, and may be anything that can heat the regenerating unit 32. For example, a radiant heater (halogen heater) , Carbon heater), sheathed heater, and nichrome heater, the same effect can be obtained, and a heat exchanger through which a high-temperature fluid flows may be provided. Hot fluids include hot water boilers, CO2R410A, CO using heat pump water heaters, hot water with cogeneration exhaust heat as the heat source, and direct expansion heat pumps as the heat source2A refrigerant such as the above may be used.
[0133]
  Further, the predetermined time Δt from the start of the bathroom drying operation to the time when the ceramic heater 35 and the drive motor 34 are turned off may not be set in advance, but may be a predetermined ratio of the drying operation time set by the controller. For example, when the predetermined ratio is set to 25% in advance and the set time for the bathroom drying operation is 4 hours,Ceramic heater 35 and drive motor 34When the energizing time is 4 hours x 25% = 1 hour from the start of operation and the set time for the bathroom drying operation is 8 hoursCeramic heater 35 and drive motor 34When the energizing time is 8 hours x 25% = 2 hours from the start of operation and the set time for bathroom drying operation is 12 hoursCeramic heater 35 and drive motor 34The energizing time is set to 12 hours × 25% = 3 hours from the start of operation, and the room for selection may be increased, so that a bathroom drying operation suitable for various bathroom sizes and various conditions may be executed.
[0134]
Also, instead of presetting a predetermined time Δt from the start of bathroom drying operation until the ceramic heater 35 and the drive motor 34 are de-energized, a temperature sensor for detecting the temperature of the circulating air is provided in the same manner as in the second embodiment. The ceramic heater 35 and the drive motor 34 may be de-energized when the temperature detected by the temperature sensor exceeds a predetermined value K from the start of the drying operation, or the humidity for detecting the humidity of the circulating air as in the third embodiment. A sensor may be provided, and the ceramic heater 35 and the drive motor 34 may be turned off when the humidity detected by the humidity sensor falls below a predetermined value H from the start of the bathroom drying operation.
[0135]
Further, although the ventilation air volume of the ventilation fan 106 is an added value of the regeneration air and the evaporation air, if further ventilation air volume is required, the ventilation fan 106 is directly sucked into the ventilation fan 106 as shown in FIG. An air path may be provided.
[0136]
Further, the regeneration air is sucked into the ventilation fan 106 and exhausted to the outside of the bathroom. However, as shown in FIG. 22, the regeneration air fan 42 is separately provided, and the internal passage 37 of the condenser 29, the ceramic heater 35, and the adsorption are provided. You may make it circulate through the reproduction | regeneration part 32 of the material 33. FIG. In this case, moisture absorbed from the circulating air in the bathroom in the moisture absorption unit 31 is dehumidified by heating it with the ceramic heater 35 in the regeneration unit 32, and the entire amount of the dehumidified moisture is condensed in the condenser 29 to form dewed water and Therefore, it is possible to increase the amount of condensation heat corresponding to the amount of condensed water to be added to the circulating air, to further increase the temperature of the circulating air, and to further enhance the evaporation effect of moisture adhering to the wall surface and floor surface of the bathroom. .
[0137]
Further, the entire amount of circulating air sucked into the main body 101 is supplied to the moisture absorbing portion 31 of the adsorbent 33. However, in order to reduce noise, the passage air speed of the moisture absorbing portion 31 is reduced as shown in FIG. As shown, a part of the circulating air may be supplied to the hygroscopic part 31.
[0138]
Further, the entire amount of circulating air sucked into the main body 101 is supplied to the external passage 38 of the condenser 29. However, in order to suppress noise, the passing air speed of the external passage 38 of the condenser 29 is reduced. As shown in FIG. 24, a part of the circulating air may be supplied to the external passage 38 of the condenser 29.
[0139]
Further, the condensed water draining means 30 collects the condensed water generated in the condenser 29 to the vaporizing filter 36, and then evaporates the air by operating the ventilation fan 106, evaporates it, and discharges it as water vapor outside the bathroom. However, it is only necessary to have a function of draining condensed water. For example, the collected condensed water may be pumped up and drained through a drain pipe, or the drain pipe may be disposed below the main body 101. It is possible to connect and drain the condensed water naturally through the drain pipe. In that case, if drainage from the drain pipe is dropped into the bathtub, simpler drainage becomes possible. When the automatic drainage function is not provided, a water collection tank may be provided in the main body 101, and the tank may be taken out and drained when a considerable amount of condensed water accumulates in the water collection tank.
[0140]
Further, in the present embodiment, when the bathroom heating operation is performed, as shown in FIG. 25, the circulation DC motor 2 is driven to operate the circulation fan 111, and the drive motor 34 and the ceramic heater 35 are energized to The adsorbent 33 is heated by 35, and the adsorbent 33 heated to the high temperature by being heated in the regeneration unit 32 is rotated by the drive motor 34 and moved to the moisture absorption unit 31, and the circulation fan 111 is operated in the moisture absorption unit 31. The heat held by the adsorbent 33 is applied to the circulating air supplied to the moisture absorption unit 31, and the circulating air becomes a high temperature and is discharged and circulated into the bathroom from the discharge port 110. Further, the adsorbent 33 whose temperature has been reduced due to heat removal in the hygroscopic portion 31 is rotated again to the regenerating portion 32 and heated by the ceramic heater 35. By repeating this operation, the air temperature in the bathroom rises and heating operation is performed. Alternatively, as shown in FIG. 26, separately from the ceramic heater 35, a radiant heater 43 as a heating means 104 is separately provided in the vicinity of the discharge port of the circulation air passage 113, and this radiant heater 43 is energized during a bathroom heating operation or a bathroom drying operation. Thus, the heating effect and the drying effect may be enhanced.
[0141]
In addition, although two ventilation units, the ventilation fan 106 and the circulation fan 111, are provided, the ventilation operation and the circulation operation may be performed by one ventilation fan 44 as shown in FIG. In this case, when only one of the ventilation operation or the circulation operation is necessary, that is, when performing the bathroom ventilation operation or the bathroom heating operation, only one of the ventilation air passage 108 or the circulation air passage 113 is closed by the damper 45. When both the ventilation operation and the circulation operation are required, that is, when the bathroom cool wind operation or the bathroom drying operation is performed, the damper 45 is fixed at an intermediate position and the ventilation air passage 108 and the circulation air passage are fixed. It suffices that both 113 are opened.
