Description

【0001】
【発明の属する技術分野】
本発明は、給湯機と有線または無線で接続された給湯機操作装置に火災報知に関わる機能を付加するためのものである。
【0002】
【従来の技術】
従来、図4に示すように給湯機5は屋外に設置され、台所7、浴室8、居間10には給湯温度の設定やふろへの自動湯張りなどの給湯機の操作を行うため給湯機5と給湯機操作装置通信線6で接続された給湯機操作装置4a、4c、4bを設置している。
また、台所7、居間10、寝室11、階段12には、それぞれ火災警報器1a、1b、1c、1dが備えられている。
さらに、住居の構造により火災警報器の発する警報音が他の居室で聞こえ難い場合は、台所7、浴室8、便所9、居間10、寝室11の各居室に他の居室で起こった火災も報知できるように外部音響装置2c、2e、2b、2d、2aが設置され、火災警報器1a、1b、1c、1dと、火災警報器通信線3aで接続されている。
なお、図4では図示していないが火災警報器1a、1b、1c、1dと外部音響装置2c、2e、2b、2d、2aには作動のための電源が必要であり、個々に電源(例えばAC100V)を接続するか電池を内蔵する必要がある。特に後者の電池式の火災警報器および外部音響装置は電源工事が不要であるため既設住宅への設置に適している。
【0003】
次に、火災警報器1(1a、1b、1c、1d)と外部音響装置2(2a、2b、2c、2d、2e)の動作を図5の火災警報器の一例を示すブロック図および図6の外部音響装置の一例を示すブロック図により説明する。
火災警報器1は、火炎検出判定回路17が火災よる熱や煙、赤外線などを検出し火災発生と判定すると、音響装置駆動回路19により火災警報器1の周辺に向けて警報音を発するとともに、火災検知信号出力回路20より火災検知信号(接点出力)を出力する。
また、火災警報器1には、火災検出判定回路17及び音響装置駆動回路19へ電源を供給する電源回路18が備えられている。電源回路18へはAC100Vを接続する。
あるいは、電源回路18の代わりに電池を内蔵しているタイプもある(例えば、特許文献1参照。)。
なお火災検知信号出力回路20と、図6に示す外部音響装置2の火災検知信号入力回路21をあらかじめ通信線により接続しておくと、火災発生時に火災警報器1の警報音に連動して外部音響装置2からも警報音を出すことができる。住居の構造により火災警報器の発する警報音が他の居室で聞こえ難い場合、この外部音響装置を該居室に設置する必要がある。
また、外部音響装置2には、音響装置駆動回路23へ電源を供給する電源回路22が備えられている。電源回路22へはAC100Vを接続する。
あるいは、電源回路22の代わりに電池を内蔵しているタイプもある。

【発明が解決しようとする課題】
火災発生を確実に居住者に知らしめ早期に消火と避難の機会を与えることが火災警報器設置の目的であり、そのため火災警報器および外部音響装置の警報音は住居内のどこでも聞こえるようにすべきである。しかしそれには外部音響装置を複数台設置する必要があり外部音響装置通信線を居室をまたがり各所に敷設することになるため大掛かりな工事が必要であり費用がかかるという問題がある。特に既設住宅に火災警報器を設置する場合、火災警報器自体は前述の電池式のものを利用すれば電源配線工事が不要になるものの外部音響装置への通信線の接続は必要であり多大な工事費用がかかるため、住居内全域で警報音が聞けるようにすることをあきらめざるをえない場合が多かった。
【0006】
これに対し、特開平7−182574に見られるように火災警報器と外部音響装置との間を無線により接続するものが考案されているが、住居全域に届く無線出力を得ようとすると火災警報器の単価が上がること、電池式のものにおいては電池寿命が短くなることという問題があり普及にはいたっていない。
従って、本発明の目的は火災警報器の火災警報を住居内各所で確認できる家庭用防災システムを、大掛かりな工事なしに安価に提供することにある。
【0007】
【課題を解決するための手段及びその作用・効果】
上記目的を達成するために請求項1記載の給湯機操作装置は、給湯機と有線または無線で接続された給湯機操作装置であって、火災警報器が発する火災検知信号の入力手段を備えるとともに、前記給湯機操作装置に接続されている給湯機もしくは前記とは別の給湯機操作装置もしくはその両方に対し、前記入力手段で入力した火災検知信号を出力する給湯機操作装置であるので、火災警報器の発する火災検知信号出力を近傍にある給湯機操作装置の火災検知信号入力を経て住居内の各所に設置された他の給湯機操作装置に送信し、前記給湯機操作装置を外部音響装置として利用して警報音や音声や文字などで居住者に火災発生を知らしめる手段を提供することができる。これにより外部音響装置の必要数と外部音響装置通信線の敷設工事が軽減され、火災警報器の火災警報を住居内各所で確認できる家庭用防災システムを、安価で提供できる。
【0008】
請求項2記載の給湯機操作装置は、請求項1記載の給湯機操作装置において、火災警報器が発する火災検知信号の入力手段と火災警報器の火災検知信号の出力回路とを通信線で接続する給湯機操作装置であるので、既存の火災警報器で外部音響装置への接続のための火災検知信号出力回路をもつものをそのまま利用することができる。
【0009】
請求項3記載の給湯機操作装置は、請求項1記載の給湯機操作装置において、火災警報器が発する火災検知信号の入力手段は火災警報器の発する無線による火災検知信号を受信する無線信号受信手段である給湯機操作装置であるので、通信線無しで火災警報器の発する無線による火災検知信号を給湯機操作装置に送信することができる。なお、火災警報器に追加する無線による送信機能は送信可能範囲を近傍にある給湯機操作装置までに限定できるので微弱電波を利用したものや赤外線を利用したものなど安価でかつ電池式での使用に耐えうる低消費電力のものが使用できる。これにより火災警報器本体の無線送信機能追加による単価上昇を押え、かつ火災警報器と給湯機操作装置を接続するための通信線敷設が不要となるため、火災警報器の火災警報を住居内各所で確認できる家庭用防災システムを安価に提供することができる。
【0010】
請求項4記載の給湯機操作装置は、請求項1記載の給湯機操作装置において、火災警報器が発する火災検知信号の入力手段は火災警報器の発する警報音を検出する警報音検出手段である給湯機操作装置であるので、火災検知信号の出力回路を持たない火災警報器を使用することができ、火災発生時には火災警報器が発した火災警報音を近傍に設置した給湯機操作装置で検出し火災検知信号として住居内の他の居室にある給湯機操作装置に送り、信号を受けた給湯機操作装置で音声や文字や絵表示による表示手段により火災の発生を居住者に知らせることができる。これにより火災警報器本体は火災検知信号の出力を持たないため安価に製造でき、かつ火災警報器と給湯機操作装置を接続するための通信線敷設が不要となるため、安価な家庭用防災システムとして提供できる。
【0011】
請求項5記載の給湯機操作装置は、請求項1記載の給湯機操作装置であって、火災警報器に電源を供給する給湯機操作装置であるため、火災警報器の電池交換もしくは電源線の設置をする必要がない。
【0012】

【0013】
請求項7記載の給湯機操作装置は、請求項6記載の給湯機操作装置であって、外部音響装置に電源を供給する給湯機操作装置であるため、外部音響装置の電池交換もしくは電源線の設置をする必要がない。
【0014】
【発明の実施の形態】
以下、本発明の実施の形態を、図面により詳細に説明する。
図1は、本発明の一実施形態に係るシステム構成図である。
台所7、居間10、寝室11および階段12にはそれぞれ火災警報器1a、1b、1c、1dが設置されており、寝室11および便所9には外部音響装置2a、2bがそれぞれ設置されている。そして火災警報器通信線3aにより火災警報器1b、1c、1dと給湯機操作装置4bが、外部音響装置通信線33aにより外部音響装置2aと給湯機操作装置4bが接続されており、火災警報器通信線3bにより火災警報器1aと給湯機操作装置4aが接続され、さらに外部音響装置通信線33cにより外部音響装置2bと給湯機操作装置4cが接続されている。給湯機操作装置4a、4b、4cは給湯機操作装置通信線6によりそれぞれ給湯機5に接続されている。なお、無線通信とすると、給湯機操作装置通信線6は不要となる。
【0015】
図2は、本発明の給湯機操作装置の一例を示す外観図である。
給湯機操作装置4aは、給湯機の運転状況や操作内容を文字や絵表示により表示するための液晶表示部14や、音声や警報音による報知のためのスピーカー15、操作のための操作スイッチ13及び24、インターホン機能により給湯機操作装置間で通話するためのマイクロホン16を備えている。
【0016】
図3は、本発明に係る給湯機操作装置のブロック図である。
給湯機操作装置4aには、操作スイッチ13、24よりの操作信号に基づいて、液晶表示部14や通信回路27を介して通信情報を処理するマイクロコンピュータ25が備えられるとともに、給湯機操作装置通信線6を介して給湯機5より供給される電力を給湯機操作装置4aを動作させるための所定電圧に調整して、マイクロコンピュータ25等に動作用電力を供給する電源回路1(26)が備えられている。
また、給湯機操作装置4aには、音声や警報音による報知のためのスピーカー15及びスピーカー15を駆動させるためのスピーカー駆動回路31、インターホン機能により給湯機操作装置間で通話するためのマイクロホン16及び音声入力回路32が備えられている。
さらに、火災警報器1より火災警報器通信線3a、3bを介して送られてくる火災検知信号を入力するための火災検知信号入力回路29、外部音響装置2へ外部音響装置通信線33a、33cを介して火災検知信号を出力する火災検知信号出力回路30が備えられている。
また、火災警報器1や外部音響装置2の動作用の電圧をつくるための電源回路2(28)が備えられている。
【0017】
次に、台所7で火災が発生した場合を例として動作を説明する。
台所7で火災が発生すると、まず火災警報器1aが、火災による熱や煙を検出し内蔵された音響装置駆動回路19により警報音を発するとともに火災検知信号出力回路20より火災検知信号を火災警報器通信線3bに出力する。給湯機操作装置4aは火災警報器通信線3b経由で火災警報器1aの発した火災検知信号を受信すると、液晶表示部14で火災発生を文字表示するとともにスピーカー15より火災発生を音声により報知し、さらに給湯機5と給湯機操作装置4b、4cに火災検知信号を給湯機操作装置通信線6を介して出力する。火災検知信号を受信した給湯機操作装置4b、4cも給湯機操作装置4aと同じように液晶表示部14で火災発生を文字表示するとともにスピーカー15より火災発生を音声により報知し、さらに外部音響装置2a、2bに外部音響装置通信線33a、33cを介して火災検知信号を出力する。火災検知信号を受信した外部音響装置2a、2bは、音響装置駆動回路23より火災発生を警報音により報知する。
【0018】
なお、図1の中では火災警報器1a、1b、1c、1dおよび外部音響装置2a、2bの電源については図示していないが、家庭用電源(AC100V)に接続するか電池を内蔵する、もしくは給湯機操作装置4に接続し、電源回路2(28)より電源を供給する。
このように図1の例は、台所7で火災が発生した場合に浴室8や便所9などを含めたすべての居室で警報音や文字や音声により居住者に報知できる防災システムでありながら、図4の従来例に較べ外部警報装置が少なく、その外部警報装置を接続するための通信線も削減できているので大掛かりな工事なしに安価に提供することができる。
また、本例では火災警報器1a、1b、1c、1dと給湯機操作装置4a、4bの間および外部音響装置2a、2bと給湯機操作装置4b、4cの間を通信線で接続したものとして説明したが、微弱電波もしくは赤外線を利用し通信線なしで火災検知信号の伝達を行えば通信線の配線工事がさらに減り、施工が容易になる。
その場合、図3に示す火災検知信号入力回路29は無線信号受信手段を備えたものとなり、また、火災検知信号出力回路30は無線信号送信手段を備えたものとなる。
そして、図5に示す火災警報器1の火災検知信号出力回路20は無線信号送信手段を備えたものとなり、図6に示す外部音響装置2の火災検知入力回路21は無線信号受信手段を備えたものとなる。
【0019】
さらに、別の方法として給湯機操作装置にインターホン用として備えたマイクロホンで火災警報器の発する警報音を検出することで火災検知信号とする方法もあり、この場合火災警報器として火災検知信号出力回路を持たない安価なものが利用できるので防災システムとして最も安価に提供することができる。
この場合は、図3に示す火災検知信号入力手段29は不要となり、火災警報器の発する警報音はマイクロホン16で検出され、音声入力回路32を介してマイクロコンピュータ25へ入力される。そして、音声入力回路32又はマイクロコンピュータ25にて警報音特有の周波数を検出して火災と判断する。
一方、図5に示す火災警報器1の火災検知信号出力回路20は不要となる。
