Description

【0001】
【発明の属する技術分野】
本発明は、浴室や台所等に給湯を行う給湯機を始めとする各種住宅設備機器を遠隔操作・制御するために使用されるリモコンに関する。
【0002】
【従来の技術】
近年、一般家庭において、浴室や台所などに給湯を行う給湯機を遠隔操作するために、浴室内や台所の壁面などにリモコンが設置され、該リモコンでのキー操作により、給湯機の始動・停止、湯温や湯量の設定などが行えるような給湯システムが普及している。図1は、こうした給湯システムの配置の一例を示す概略図である。この例では、屋外にガス燃焼式の給湯機(熱源)1が設置され、屋内の浴室5及び台所6に浴室リモコン2及び台所リモコン3がそれぞれ設置されている。給湯機1、浴室リモコン2及び台所リモコン3は居宅の壁面内や屋根裏等に配設された通信線4に接続されており、浴室リモコン2及び台所リモコン3のいずれからも給湯機1の運転に関する操作が可能となっている。なお、給湯機1がガス燃焼式でなく電気式である場合には通常屋内に設置されるが、その場合でも、通信線4を介してリモコン2、3と接続される点は同様である。最近、幼児などの入浴者の安全を確保すべく操作に対して制限を設けるようチャイルドロックなる機能が存在している。(例えば、特許文献1参照。)
【0003】
【特許文献1】
実用新案第2560789号
【0004】
【発明が解決しようとする課題】
上記チャイルドロック機能で第二のリモコンにて動作させると安全性の意味合いから解除できるのは第一のリモコンが権利を持っていることが多いが、第一のリモコンが通信不良もしくは接続解除された場合、前記チャイルドロックの解除する方法がなく非常に不便を強いられてしまう。また、上記チャイルドロック機能を設定した操作者が第二のリモコンで同機能を解除する必要があった時、操作者は第一のリモコンの設置場所まで移動することになり非常に利便性に乏しくなってしまう。
【0005】
【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は、給湯機等の住宅設備機器と該機器を遠隔操作するための複数のリモコン間で相互にデータ送受信を行うための送受信装置と、前記複数のリモコン間の通信方式としてデジタル変調を利用した通信を行い、前記複数の第一のリモコンが前記複数の第二のリモコンに対して第二のリモコン自身のキー操作を受け付けなくするチャイルドロック機能が設定可能である住宅設備機器用リモコンシステムにおいて、前記第二のリモコンは自分自身で所定のキー操作解除判断を行う解除判断手段を有するとともに、前記解除判断手段の出力に応じて前記チャイルドロック機能が設定・解除可能であることを特徴とする。
この結果、従来幼児等の入浴時いたずらを防止するために、第二のリモコンで第一のリモコンにチャイルドロックが設定されていて、そのあとに大人がチャイルドロックを解除し忘れて入浴していても、第二のリモコンの所定の操作等で解除可能である。そのため、わざわざ浴室を出て第二のリモコンのところまで出て必要がなくなる。
【0006】
また、請求項2は請求項1記載の住宅設備機器用リモコンシステムにおいて、前記解除判断手段は前記第一のリモコンのネットワーク接続への有無若しくは通信不能の判断によることを特徴とする。
これにより、第一のリモコンの故障時には、第二のリモコンでの所定の操作等で解除可能になるので、第一のリモコンが直らなくても問題なくなる。
【0007】
また、請求項3は請求項1又は2記載の住宅設備機器用リモコンシステムにおいて、前記チャイルドロック機能の設定・解除状況が行われたリモコン以外の他のリモコンで前記報設定・解除状況を表示または報知できるように構成されたことを特徴とする。
これにより、チャイルドロック機能の設定・解除状況が行われたリモコン以外の他のリモコンで前記報設定・解除状況を表示または報知できるようになるので、他の場所のリモコンで所定のリモコンのチャイルドロック機能の設定状況が確認できて便利である。
【0008】
【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、本実施例を適用する給湯システムを表す。この給湯システムでは、従来通り、浴室リモコン2及び台所リモコン3からキー操作を行うと、その操作に応じた制御データが通信線4を介して給湯機1へと伝送され、給湯機1の動作が制御されるようになっている。また、それ以外に、浴室リモコン2と台所リモコン3との間で通話が行えるようになっている。浴室リモコン2及び台所リモコン3は基本的には同一の構成を有している。
【0009】
図2はこのリモコンの電気系の機能的構成を示すブロック図である。制御の中心には、CPU101、タイマ102、ROM103、RAM104等を含む中央制御部10が据えられ、中央制御部10には通信処理部11、操作部12、表示制御部13、音声入出力制御部15等が接続されている。通信処理部11は、機能的に搬送波信号生成部111、分離・混合部112、変復調部113等を備える。搬送波信号生成部111はASK変調に必要な250kHzと1MHzの2つの搬送波信号を生成する。
【0010】
図3に示したように、250kHzの搬送波は制御データのASKに、1MHzの搬送波は音声データのASKに利用される。変復調部113は変調部と復調部とから成り、変調部では中央制御部10から与えられるデジタル信号に応じて2つの搬送波信号をそれぞれ振幅変調する。一方、復調部では分離・混合部112から与えられる2系統のASK信号を検波して、元のデジタル信号列を取り出して中央制御部10へと送る。分離・混合部112は、送信時には2系統のASK信号を重畳して通信線4へと送出し、受信時には、重畳されている2系統のASK信号を周波数帯域で分離して変復調部113へと与える。操作部12は給湯機1の動作制御のための各種操作キーを含み、これらの操作キーが操作される度に、操作内容に応じた信号を中央制御部10へ送る。表示制御部13は中央制御部10の指示に従って、LEDやLCDから成る表示器14を用いて視覚的に情報を表示する。また、音声入出力制御部15は、マイク17から入力された音声信号を適宜に増幅した後にデジタル信号に変換して中央制御部10へと送る一方、スピーカ16を用いて他のリモコンから送られて来た音声やブザー音等を出力する。中央制御部10は、操作部12からの操作指示信号や、通信処理部11を通じて給湯機1から送られて来る各種信号及び他のリモコンから送られて来る音声信号を所定の方法で処理し、その処理結果に応じて表示制御部13や音声入出力制御部15へ情報表示や音声出力に関する信号を送ったり、通信処理部11を通じて給湯機1へ制御信号を送ったり、同じく通信処理部11を通じて他のリモコンへ音声信号を送ったりする。なお、中央制御部10やその周囲の回路の一部は、マイクロコンピュータを中心に具現化することができ、該マイクロコンピュータが内蔵する又は外付けのROMに格納した制御プログラムを実行することにより、各種の制御を遂行することができる。
【0011】
本実施例の給湯システムでは、台所リモコン3と浴室リモコン2との間で行われる通話のための通信路を確立すべく実行される各リモコン2、3での動作に特徴を有する。操作部12には容易に操作ができないようにするいわゆるチャイルドロックスイッチを設けてある。台所リモコン3と浴室リモコン2に夫々設けており、台所リモコン3と浴室リモコン2が接続されておりかつ相互に通信できる状態においては、このチャイルドロックの設定は台所リモコン3と浴室リモコン2のどちらからでも可能なように設定されている。解除するのは台所リモコン3のみとなっている。即ちチャイルドロック機能に関しては台所リモコン3は主たる設定と解除の権利をもち、浴室リモコンは従たる設定の権利のみをもつ。チャイルドロックに関する状態変化については夫々前記の通信処理部11を介して他方に伝達されるよう構成されている。ここで通信路が何らかの事故で断線し、台所リモコン3と通信できなくなった場合には台所リモコン3からの受信データが無いことを浴室リモコン2の方で検知すると、浴室リモコン2の操作部12においてチャイルドロックスイッチを設定のみならず解除もできる権利を与えるよう制御する。
【0012】
さらに、台所リモコン3が修理などによって通信可能な状態になれば浴室リモコン2では台所リモコン3が接続されていることを検知次第チャイルドロックスイッチの機能に関して設定のみの権利に戻すよう制御する。前記処理を図4のフローチャートに基づいて以下に説明していく。浴室リモコン2のチャイルドロックスイッチを操作されると(S10)まず自身の状態がチャイルドロック中であるかどうか判断する。(S11)結果YESであった場合台所リモコン3が接続されているか否か判断する。(S12)結果NOであった場合即ち台所リモコン3が接続されていない場合はチャイルドロックを解除する。(S13)また、前記S11でチャイルドロック中で無い場合はチャイルドロックを設定する。(S14)さらに、S12の結果YESの場合即ち台所リモコン3が接続されている場合は何もしないで終了となる。こうすることにより台所リモコンが故障などになった場合でもチャイルドロックスイッチの機能を十分に活用することができる。
【0013】
【別実施例】
上記実施例ではチャイルドロックスイッチの機能に関して主たる設定、解除を台所リモコン3側に、従たる設定を浴室リモコン側にしてあるが、台所リモコン3で夫々の権限に関して別に設定できるようにしてもよい。即ち主たる設定、解除を浴室リモコン2側にし、従たる設定を台所リモコン3側にすることで使用者の使い勝手を更に向上することも可能となる。
