Description

【０００１】
【発明の属する技術分野】
本発明は、浴室の天井裏等に設置して浴室内の暖房を行う浴室暖房機本体に取り付けられて、浴室を含む脱衣室及びトイレ等の複数室の換気を行うことができる浴室暖房機の換気装置に関する。
【０００２】
【従来の技術】
従来、浴室の天井板に開口部を設け、この開口部の天井裏に設置して浴室内の暖房及び換気をする浴室暖房機本体と、この浴室暖房機本体側板に取り付けて浴室、脱衣室及びトイレの換気を行う換気装置とが開示されている（例えば、特許文献１参照。）。
【０００３】
この種の浴室暖房機の本体は、箱体状の本体ケースを有し、この本体ケース内に外部の熱源機等から温水の供給される熱交換器と、浴室内から空気を吸い込み熱交換器を介して熱交換された空気を浴室内に吹き出す温風ファンと、浴室内の空気を換気する換気ファンとを備え、本体ケースの側板に浴室換気用の送出口が設けられている。また、本体ケースの底面には吸込口及び吹出口を有する吸込グリルが取り付けられている。
【０００４】
前記換気装置は箱体状のケース（以下換気ケースという）内に通風路を形成しこの通風路内に換気ファンを設け、換気ケースの一側板に本体の送出口へ連通する連通口を設け、別の側板に脱衣室及びトイレ用の２つの吸気口を設け、さらに別の側板に連通口及び２つの吸気口から吸い込まれた空気を排出する排気口を設けている。２つの吸気口にはダクト接続具を介して各室に連通する吸気ダクトが接続され、排気口にはダクト接続具を介して室外に連通する排気ダクトが接続されている。
【０００５】
そして、浴室換気用ファンと別室換気用ファンとを作動することにより浴室の換気を行うことができ、別室換気用ファンのみを作動することにより脱衣室及びトイレの換気を行うことができる。

【発明が解決しようとする課題】
ところで、前述した換気装置の設置工事において、本体近傍の天井には点検口が設けられ、この点検口は、天井の強度や取扱上、換気装置の出し入れができる最小限の大きさになっており、換気装置の外形寸法（縦×横）より少しだけ大きくなっている。そしてこの点検口を通して、浴室暖房機本体の設置後に、換気装置の設置作業が行われる。
【０００８】
ここで、ダクト接続具を換気装置に取り付けたとき、ダクト接続具は換気装置の外方に突出するために点検口を通すことが難しくなる。そこで、ダクト接続具の換気装置への着脱は、天井裏で行われることになり、狭い場所での作業を容易にするためにダクト接続具の着脱作業はできるだけ簡単にする必要があった。
【０００９】
本発明は上述のような従来の事情に鑑みなされものであり、浴室の天井裏等に設置される浴室暖房機本体に取り付けられる換気ケースを備えた浴室暖房機の換気装置において、ダクトの着脱作業を容易にし、設置作業性及びサービス性の向上を図ることを目的とする。
【００１０】
【課題を解決するための手段】
請求項１に記載の本発明では、浴室（Ａ）の天井裏（Ｂ）に設置される箱体状の浴室暖房機本体（２）に取り付けられる箱体状の換気ケース（６）を有し、この換気ケース（６）の側板（６ｂ、６ｃ）には、吸気口（８、９）と排気口（１０）とが設けられ、これら吸気口（８、９）と排気口（１０）には、それぞれ取付枠（３１）及びダクト接続具（３１ａ、３１ｂ）を介してダクト（１５、１７、１８）が接続される構成とした浴室暖房機の換気装置において、前記取付枠（３１）は、角筒状に形成されると共に、それの一側板（３３ｄ）に係合孔（３５）が設けられ、かつ、この係合孔（３５）が設けられた一側板（３３ｄ）に対向する他の側板（３３ａ）には、スライド可能な掛止部（３４）が設けられており、前記ダクト接続具（３１ａ、３１ｂ）は、前記ダクト（１５、１７、１８）を連結する円筒部（４２）とフランジ部（４４）とを有すると共に、このフランジ部（４４）には、前記取付枠（３１）に内嵌めされてその取付枠（３１）の内周面に接する内接板（４７ａ、４７ｂ、４７ｃ、４７ｄ）と、前記取付枠（３１）の係合孔（３５）に係合する突起片（４８）と、この突起片（４８）に対向する位置に設けられて前記取付枠（３１）を押える押え板（４５）と、前記取付枠（３１）の掛止部（３４）が掛け止めされる被掛止部（４６ａ）とが設けられていることを特徴とする。

【００１２】
【発明の実施の形態】
以下、本発明の一実施形態を図面に基づいて説明する。図１は本発明の一実施形態における浴室暖房機の設置構成図、図２は図１の浴室暖房機の平面図である。
【００１３】
図１、図２において、浴室暖房機１は、浴室Ａの天井裏Ｂ等に設置される浴室暖房機本体２及び換気装置３と、前記浴室暖房機本体２に温水等の熱媒を供給する熱源機４とを備え、温水配管５にて接続されている。換気装置３の各側板には、本体に連通する連通口（図示せず）、脱衣室用吸気口８、トイレ用吸気口９及び排気口１０が設けられ、連通口は浴室暖房機本体２を介して浴室Ａに連通し、脱衣室用吸気口８は吸気ダクト１５を介して脱衣室Ｃに連通し、トイレ用吸気口９は吸気ダクト１７を介してトイレＤに連通し、排気口１０は排気ダクト１８を介して室外に連通している。前記ダクト１５、１７、１８は、浴室Ａ、脱衣室Ｃ及びトイレＤの天井裏Ｂに配設されている。また、浴室暖房機１には、浴室暖房機本体２及び換気装置３を操作するためのリモコン２１が設けられ、リモコン２１及び浴室暖房機本体２間、並びに浴室暖房機本体２及び熱源機３間が信号線２２にて接続されている。
【００１４】
前記浴室暖房機本体２は箱体状の本体ケース２Ａを有し、この本体ケース２Ａ内に外部の熱源機４等から温水が供給される熱交換器（図示せず）と、浴室Ａ内から空気を吸い込み、熱交換器を介して熱交換された空気を浴室Ａ内に吹き出す温風ファン（図示せず）と、浴室Ａ内の空気を換気する浴室換気用ファン２５とを備え、本体ケース２Ａの側板には、浴室換気用の送出口（図示せず）が形成されている。浴室暖房機本体２は、浴室Ａの天井に設けられた天井開口部の裏側に４本の吊りボルトにて吊り下げられて設置され、この本体２の底面には、天井開口部を塞ぐように天井面に設けられる吸込グリル２６がねじ止め固定される。この吸込グリル２６には、吸込口と吹出口（図示せず）が設けられ、この吸込口は前記送出口に連通している。
【００１５】
前記換気装置３は箱体状の換気ケース６を有し、この換気ケース６内には通風路が形成されて通風路内に換気ファン２４が設けられ、通風路は換気ケース６の側板６ａ、６ｂ、６ｃに形成された複数の開口に連通している。これら開口は、本体２の送出口に連通する連通口と、別の側板６ｂに形成された２つの別室用の吸気口８、９と、さらに別の側板６ｃに形成された排気口１０であり、各開口には通風を開放遮断する開閉ダンパ（図示せず）が設けられている。また脱衣室用の吸気口８には、脱衣室Ｃに連通する吸気ダクト１５が接続され、トイレ用の吸気口９には、トイレＤに連通する吸気ダクト１７が接続され、排気口１０には、室外に連通する排気ダクト１８が接続される。
【００１６】
また、換気装置３近傍の天井板には、浴室暖房機１の設置及び点検等を行うための点検口２３が設けられ、この点検口２３は、天井強度や取扱上、換気装置３の外形寸法（縦×横）より少しだけ大き目に作られ、換気装置の出し入れができるようになっている。
【００１７】
図３は、換気装置の吸気口とダクト接続具とを上方から見た斜視図、図４は、換気装置の吸気口とダクト接続具とを下方から見た斜視図である。
【００１８】
図３、図４において、前記吸気口８には、外方に突出する四角筒状の取付枠３１が設けられ、この取付枠３１の上側板３３ａには、吸気口８の正面から見て左右にスライドするＵ字状の掛止部３４が設けられ、この掛止部３４を左方向（実線矢印）へスライドさせることによりダクト接続具４１の上部を固定し、右方向へスライドさせることにより固定が解除される。また、下側板３３ｄには横長の係合孔３５が設けられている。
【００１９】
前記ダクト接続具４１は、一端側にダクトを連結する円筒部４２と、他端側に換気装置３へ接続される四角形のフランジ部４４とを有しており、円筒部４２には円筒形のダクトが外嵌されテープ止めにて気密に接続される。フランジ部４４の上辺、左辺、右辺及び下辺には、図４に示すように、換気装置３側へ突出する内接板４７ａ、４７ｂ、４７ｃ、４７ｄが設けられ、これら内接板４７ａ、４７ｂ、４７ｃ、４７ｄは、取付枠３１に内嵌めされてその取付枠３１の側板３３ａ、３３ｂ、３３ｃ、３３ｄに内接するようになっている。内接板の上板４７ａは中央部を切欠いて２つに分けて設けられ、左右両板４７ｂ、４７ｃは下から上にかけて突出幅が狭くなるように形成され、下板４７ｄは上板４７ａよりも突出幅が広く形成されている。そして下板４７ｄの下面には下方に突出する突起片４８が設けられ、この突起片４８が係合孔３５に係合するようになっている。また、フランジ部４４の上部には換気装置３側へ突出する押え板４５と突起部４６とが設けられている。突起部４６には上方に突出するボス４６ａ（被掛止部）を有してフランジ部４４の中央に設けられ、押え板４５は突起部４６に隣接して設けられている。
【００２０】
次に、ダクト接続具を吸込口の取付枠に取り付ける作業について説明する。
【００２１】
図３〜図６において、取付枠３１の掛止部３４を固定解除の位置にしておき、フランジ部４４の下部が先になるように斜めに倒してダクト接続具４１を取付枠３１の内側に挿入する。突起片４８を係合孔３５に挿入し、突起片４８を中心にダクト接続具４１を回動し、内接板４７ａ、４７ｂ、４７ｃ、４７ｄを取付枠３１の側板３３ａ、３３ｂ、３３ｃ、３３ｄに嵌合する。このとき左右内接板４７ｂ、４７ｃの突出幅が下から上にかけて狭くなっているので、ダクト接続具４１はスムーズに回動される。フランジ部４４が取付枠３１の先端に当接するとともに、図５に示すように、押え板４５が上側板３３ａの上面を押える。これにより、上側板３３ａが内接板４７ａと押え板４５とで挟持され、ダクト接続具４１が取付枠３１に仮固定される。
【００２２】
次に、掛止部３４を、図５の実線矢印方向にスライドすることにより、図６に示すように、突起部４６のボス４６ａ（被掛止部）が、掛止部３４のＵ字部分の内側で押えられて掛け止めされ、ダクト接続具４１が、取付枠３１に対して確実に、かつ、気密に固定される。
【００２３】
このように、換気装置３へのダクト接続具４１の取付作業が容易であるので、これらの作業を片手でも行うことができ、狭い天井裏Ｂでの作業を簡単に行うことができる。また、ダクト接続具４１を取付枠３１に取付後、取付枠３１から外す際には、取付作業と逆の手順で作業することにより簡単に取外し作業を行うことができる。
【００２４】
なお、排気口９も吸気口８と同様の構成になっており、同様の方法でダクト接続具４１を取付枠３１に着脱することができる。
【００２５】
以上、一実施形態に基づいて本発明を説明したが、本発明はこれに限定されるものではない。
【００２６】
【発明の効果】
以上説明したように、本発明の浴室暖房機の換気装置は、浴室の天井裏に設置される箱体状の浴室暖房機本体に取り付けられる箱体状の換気ケースを有し、この換気ケースの側板には、吸気口と排気口とが設けられ、これら吸気口と排気口には、それぞれ取付枠及びダクト接続具を介してダクトが接続される構成とした浴室暖房機の換気装置において、前記取付枠は、角筒状に形成されると共に、それの一側板に係合孔が設けられ、かつ、この係合孔が設けられた一側板に対向する他の側板には、スライド可能な掛止部が設けられており、前記ダクト接続具は、前記ダクトを連結する円筒部とフランジ部とを有すると共に、このフランジ部には、前記取付枠に内嵌めされてその取付枠の内周面に接する内接板と、前記取付枠の係合孔に係合する突起片と、この突起片に対向する位置に設けられて前記取付枠を押える押え板と、前記取付枠の掛止部が掛け止めされる被掛止部とが設けられている構成であるから、ダクトが連結されたダクト接続具が取付枠に片手でも取り付けられるため、天井裏等の狭い場所でのダクトの取付作業を簡単に行うことができる。
【００２７】
さらに、取付枠の掛止部を片手でも操作できるようにスライド可能としたので、狭い場所での作業を一層簡単に行うことができる。
【００２８】
また、ダクト接続具を取付枠から外す際にも、簡単に取外し作業を行うことができる。
【００２９】
これにより、浴室暖房機の換気装置へのダクトの接続作業の効率化が図れるとともに、サービス性の向上を図ることができる。

[0026]
【The invention's effect】
As described above, the ventilation device for a bathroom heater according to the present invention has a box-shaped ventilation case attached to the box-shaped bathroom heater body installed on the back of the ceiling of the bathroom. The side plate is provided with an air inlet and an air outlet, and the air inlet and the air outlet are connected to a duct via a mounting frame and a duct connector, respectively. The mounting frame is formed in a rectangular tube shape, and an engagement hole is provided in one side plate thereof, and the other side plate opposed to the one side plate provided with the engagement hole is slidably hooked. A stop portion is provided, and the duct connector has a cylindrical portion and a flange portion for connecting the duct, and the flange portion is fitted into the mounting frame and is attached to the inner peripheral surface of the mounting frame. Engaging with the inscribed plate in contact with the engaging hole of the mounting frame Since the projection piece, the holding plate that is provided at a position facing the projection piece and presses the mounting frame, and the latched portion that latches the latching portion of the mounting frame are provided. , since the duct connected to the duct connecting device also mounted with one hand to the mounting frame, it is possible to perform the mounting operation of ducts in a narrow place ceiling or the like easily.
[0027]
Furthermore, since the latching portion of the mounting frame can be slid so that it can be operated with one hand, the work in a narrow place can be performed more easily.
[0028]
Also, when removing the duct connector from the mounting frame, the removal work can be easily performed.
[0029]
Thereby, efficiency of the connection work of the duct to the ventilator of the bathroom heater can be improved, and the serviceability can be improved.
