Description

【０００１】
【発明の属する技術分野】
本発明は、温風を吹き出して室内を暖房する温風暖房装置に関するものである。
【０００２】
【従来の技術】
従来、この種の温風暖房機としては図８に示すように、例えば表示器を突出して設け、機器正面、両側面、上面より運転状態が発光により確認できる構成とした灯油を使用した温風暖房機がある。
【０００３】
図８において、１０１は温風暖房機本体で、１０２は前面上部に備えられた運転等の操作部、１０３は温風を吹き出すルーバ１０４を取り付けた温風吹出し口、１０５は温風暖房機本体１０１の背面の空気取入れ口１０６に取り付けられた対流用ファン、１０７はバーナヘッド部１０８を突出して設けたバーナ部で、１０９はバーナヘッド１０８を囲み燃焼空間を形成する燃焼筒である。
【０００４】
１１０は操作部１０２と温風吹き出し口１０３との間における温風暖房機本体１０１の前面上部で、その幅中央部に設けたカラー表示部で、赤色及び緑色の２色発光する発光部１１１と、この発光部１１１の光をカラー表示部１１０の周囲に拡散させる拡散レンズ１１２とにより構成されている（例えば、特許文献１参照）。
【０００５】
しかしながら、前記従来の構成では、表示器であるカラー表示部１１０の拡散レンズ１１２を突出して設け、機器正面、両側面、上面より運転状態が発光により確認できるものであるが、温風暖房機本体１０１の前面上部の一定の高さ位置で、かつ幅方向の中央部であるため、表示器が小さくなり、遠くからはその運転状態がはっきりと確認できないという課題を有していた。特に、ガスを燃料に使用した温風暖房機では燃焼時の運転音が静かになり、弱燃焼の場合は騒音が２２ｄＢと低く、燃焼しているかどうか一目で確認でき難くなり、消し忘れて燃焼しっぱなしの状態になることが考えられる。さらに、表示器および温風吹き出し口１０３の位置する以外の温風暖房機本体１０１の前面大半は、本体ケースの前面そのままで、結果的に内部構造物が見えないようにする機能以外、全く利用されることのない構造であった。

【発明が解決しようとする課題】
上記従来の技術の問題点に鑑み、本発明が解決しようとする課題は、温風暖房装置の広範囲な前面を利用して視覚暖房感と装置の使用状況の表示効果を高めた温風暖房装置を提供することにある。
【０００８】
【課題を解決するための手段】
上記目的を達成するために本発明の温風暖房装置は、本体ケース内に設けた温風暖房部と、視覚暖房部と、前記温風暖房部および視覚暖房部を制御する制御手段とを備え、前記温風暖房部はバーナと、前記バーナからの燃焼ガスと外部より取り込んだ空気を混合する燃焼室と、前記空気を吸引し、かつ前記燃焼ガスと空気の混合した温風を送出する第一の対流用ファンと、前記本体ケースの下部前面に設けた温風吹出し口と、燃焼用の空気を取り込む対流用フィルターとで構成し、前記視覚暖房部は前記温風吹出し口の上部に位置する本体ケースの前面部分と前記燃焼室との間に配設し、複数の発光体と、前記本体ケースの前面を形成し、外から内部が見えなくて前記発光体の発光により視覚暖房像が映る前面板と、空気流を受けて揺らぎ、発光を受けて反射する視覚暖房像形成体と、前記空気流を発生する第二の対流用ファンとで構成し、前記制御手段は前記バーナへ供給する燃料の量と第一の対流用ファンの回転数で定まる燃焼量を制御する温風暖房制御部と、前記複数の発光体を発光させる制御および前記第二の対流用ファンの回転数の制御を行う視覚暖房制御部とで構成し、かつ前記視覚暖房制御部を前記温風暖房制御部に連動させ、前記複数の発光体への通電回数と通電量、および前記第二の対流用ファンの回転数を前記燃焼量に比例して可変させる制御にしたものである。
【０００９】
上記手段によって、温風暖房に連動した視覚暖房感とその運転状況の表示が、揺らぎながら光を反射する視覚暖房像と温風吹出し口を除く本体ケースの広範囲な前面を有効に利用して行なえ、遠くからでも一目で機器の運転状態が確認でき、さらに機器の運転状況に応じた適切な表示が行なえる。
【００１０】
また、上記の連動が比例していることにより、発光量と視覚暖房像の揺らぎ度合いは燃焼量に連動して細やかに表示ができ、遠くからでも一目で機器の運転状態が確認できる。
【００１１】
また、本発明の温風暖房装置は、本体ケース内に設けた温風暖房部と、視覚暖房部と、前記温風暖房部および視覚暖房部を制御する制御手段とを備え、前記温風暖房部はバーナと、前記バーナからの燃焼ガスと外部より取り込んだ空気を混合する燃焼室と、前記空気を吸引し、かつ前記燃焼ガスと空気の混合した温風を送出する第一の対流用ファンと、前記本体ケースの下部前面に設けた温風吹出し口と、前記温風吹出し口に接続し、かつ前記燃焼室を覆い、温風を案内する温風ガイドと、燃焼用の空気を取り込む対流用フィルターとで構成し、前記視覚暖房部は前記温風吹出し口の上部に位置する本体ケースの前面部分と前記燃焼室との間に配設した視覚暖房ケースと、前記視覚暖房ケース内に設けた複数の発光体と、前記視覚暖房ケースの前面に対向して前記本体ケースの前面を形成し、外から内部が見えなくて前記発光体の発光により視覚暖房像が映る前面板と、前記視覚暖房ケース内に設け、空気流を受けて揺らぎ、かつ発光を受けて反射する視覚暖房像形成体と、前記温風以外の空気を吸引し、前記視覚暖房ケース外に排出して前記空気流を発生する第二の対流用ファンとで構成し、前記制御手段は前記バーナへ供給する燃料の量と第一の対流用ファンの回転数で定まる燃焼量を制御する温風暖房制御部と、前記複数の発光体を発光させる制御および前記第二の対流用ファンの回転数の制御を行う視覚暖房制御部とで構成し、かつ前記視覚暖房制御部を前記温風暖房制御部の制御状況に応じて連動させる制御にしたものである。
【００１２】
上記手段によって、温風暖房に連動した視覚暖房感とその運転状況の表示が、揺らぎながら光を反射する視覚暖房像と温風吹出し口を除く本体ケースの広範囲な前面を有効に利用して行なえ、遠くからでも一目で機器の運転状態が確認でき、さらに機器の運転状況に応じた適切な表示ができる。
【００１３】
また、視覚暖房部は視覚暖房ケース内に、視覚暖房像形成体を揺らす専用の第二の対流ファンを利用し、かつ温度の比較的に低い空気流を生じさせるので、構成簡単にして冷却効果が得られて温風暖房部の熱影響に左右されず、視覚暖房感とその運転状況の表示を優先（極めて見やすい、温風吹出し口を除く本体ケースの広範囲な前面を有効に利用）した配置ができる。
【００１４】
【発明の実施の形態】
上記した本発明の目的は、各請求項に記載した構成を実施の形態とすることにより達成できるので、以下には各請求項の構成にその構成による作用効果を併記し併せて請求項記載の構成のうち説明を必要とする特定用語については詳細な説明を加えて本発明の実施の形態とする。
【００１５】
請求項１記載に係る発明は、本体ケース内に設けた温風暖房部と、視覚暖房部と、前記温風暖房部および視覚暖房部を制御する制御手段とを備え、前記温風暖房部はバーナと、前記バーナからの燃焼ガスと外部より取り込んだ空気を混合する燃焼室と、前記空気を吸引し、かつ前記燃焼ガスと空気の混合した温風を送出する第一の対流用ファンと、前記本体ケースの下部前面に設けた温風吹出し口と、燃焼用の空気を取り込む対流用フィルターとで構成し、前記視覚暖房部は前記温風吹出し口の上部に位置する本体ケースの前面部分と前記燃焼室との間に配設し、複数の発光体と、前記本体ケースの前面を形成し、外から内部が見えなくて前記発光体の発光により視覚暖房像が映る前面板と、空気流を受けて揺らぎ、発光を受けて反射する視覚暖房像形成体と、前記空気流を発生する第二の対流用ファンとで構成し、前記制御手段は前記バーナへ供給する燃料の量と第一の対流用ファンの回転数で定まる燃焼量を制御する温風暖房制御部と、前記複数の発光体を発光させる制御および前記第二の対流用ファンの回転数の制御を行う視覚暖房制御部とで構成し、かつ前記視覚暖房制御部を前記温風暖房制御部に連動すべく、前記複数の発光体への通電回数と通電量、および前記第二の対流用ファンの回転数を前記燃焼量に比例して可変させる制御にした温風暖房装置である。
【００１６】
この実施の形態によると、制御手段の温風暖房制御部により温風暖房部の運転が開始されると同時に、視覚暖房制御部により視覚暖房部の複数の発光体は通電されて発光状態となり、第二の対流用ファンは起動されて空気流を発生し、この空気流と発光を受けて視覚暖房像形成体が揺らぎながら光を反射し、この視覚暖房像を受けた前面板が前記の像を映すのである。
【００１７】
従って、燃料が燃焼する炎を擬似的に見せる上で、より実際の炎のように見せることができるため、暖かさを視覚で感じることができるとともに、擬似的な炎像が映る温風吹出し口を除く本体ケースの広範囲な前面を通じて遠くからでも一目で機器の運転状態が確認でき、かつ広範囲な本体ケースの前面を、本体ケースの内部構造物が見えないようにする機能を維持しつつ、有効に利用して明確な運転表示が可能になる。
【００１８】
また、上記の視覚暖房制御部が温風暖房制御部に連動、かつ比例していることにより、運転能力状態も容易に確認できる。例えば、温風暖房部の燃焼量が最大量の場合は発光体も最大の明るさとし、かつ第二の対流用ファンの回転数も最大にして視覚暖房像形成体、例えばリボン状反射部材を大きく揺らぐようにする。逆に燃焼量が最小量の場合は発光体も最小の明るさまで低下させ、かつ第二の対流用ファンの回転数も最小にして視覚暖房像形成体、例えばリボン状反射部材の揺らぎを抑える。このようにして、擬似的な炎をより現実的に演出することができる。
【００１９】
請求項２記載に係る発明は、本体ケース内に設けた温風暖房部と、視覚暖房部と、前記温風暖房部および視覚暖房部を制御する制御手段とを備え、前記温風暖房部はバーナと、前記バーナからの燃焼ガスと外部より取り込んだ空気を混合する燃焼室と、前記空気を吸引し、かつ前記燃焼ガスと空気の混合した温風を送出する第一の対流用ファンと、前記本体ケースの下部前面に設けた温風吹出し口と、前記温風吹出し口に接続し、かつ前記燃焼室を覆い、温風を案内する温風ガイドと、燃焼用の空気を取り込む対流用フィルターとで構成し、前記視覚暖房部は前記温風吹出し口の上部に位置する本体ケースの前面部分と前記燃焼室との間に配設した視覚暖房ケースと、前記視覚暖房ケース内に設けた複数の発光体と、前記視覚暖房ケースの前面に対向して前記本体ケースの前面を形成し、外から内部が見えなくて前記発光体の発光により視覚暖房像が映る前面板と、前記視覚暖房ケース内に設け、空気流を受けて揺らぎ、かつ発光を受けて反射する視覚暖房像形成体と、前記温風以外の空気を吸引し、前記視覚暖房ケース外に排出して前記空気流を発生する第二の対流用ファンとで構成し、前記制御手段は前記バーナへ供給する燃料の量と第一の対流用ファンの回転数で定まる燃焼量を制御する温風暖房制御部と、前記複数の発光体を発光させる制御および前記第二の対流用ファンの回転数の制御を行う視覚暖房制御部とで構成し、かつ前記視覚暖房制御部を前記温風暖房制御部の制御状況に応じて連動させる制御にしたものである。
【００２０】
この実施の形態によると、制御手段の温風暖房制御部により温風暖房部の運転が開始されると同時に、視覚暖房制御部により視覚暖房部の複数の発光体は通電されて発光状態となり、第二の対流用ファンは起動されて空気流を発生し、この空気流と発光を受けて視覚暖房像形成体が揺らぎながら光を反射し、この視覚暖房像を受けた前面板が前記の像を映すのである。
【００２１】
従って、燃料が燃焼する炎を擬似的に見せる上で、より実際の炎のように見せることができるため、暖かさを視覚で感じることができるとともに、擬似的な炎像が映る温風吹出し口を除く本体ケースの広範囲な前面を通じて遠くからでも一目で機器の運転状態が確認でき、かつ広範囲な本体ケースの前面を、本体ケースの内部構造物が見えないようにする機能を維持しつつ、有効に利用して明確な運転表示が可能になる。
【００２２】
また、視覚暖房部は視覚暖房ケース内に、発光体と、視覚暖房像形成体と、視覚暖房像形成体を揺らす専用の第二の対流ファンとが内装され、かつ第二の対流ファンにより温度の比較的に低い空気流を生じさせるので、空気流により視覚暖房像形成体が炎のように揺れながら光反射するだけでなく、構成簡単にして視覚暖房ケース内に冷却作用が得られ、温風暖房部の前側で、かつ本体ケースの広範囲な前面であっても温風暖房部の熱影響に左右されず、視覚暖房感とその運転状況の表示を、極めて見やすい、温風吹出し口を除く本体ケースの広範囲な前面を有効に利用して優先的に配置が可能になる。
【００２３】
また、上記の視覚暖房制御部が温風暖房制御部に連動、かつ比例していることにより、運転能力状態も容易に確認できる。例えば、温風暖房部の燃焼量が最大量の場合は発光体も最大の明るさとし、かつ第二の対流用ファンの回転数も最大にして視覚暖房像形成体、例えばリボン状反射部材を大きく揺らぐようにする。逆に燃焼量が最小量の場合は発光体も最小の明るさまで低下させ、かつ第二の対流用ファンの回転数も最小にして視覚暖房像形成体、例えばリボン状反射部材の揺らぎを抑える。このようにして、擬似的な炎をより現実的である暖房能力に合わせて演出することができる。
【００２４】
請求項３記載に係る発明は、請求項１または２記載の温風暖房装置にあって、制御手段は、温風暖房制御部の動作に連動する視覚暖房制御部の前記連動の有無を選択する選択スイッチを設けたもので、選択スイッチの操作による選択有り、または選択無しで視覚暖房制御部による視覚暖房部は温風暖房部に連動して動作、または動作しなくなり、温風暖房装置の使用状態や環境および使用者の好みなどにより自由に選択して使用することが可能になる。
【００２５】
例えば、視覚暖房部が明るいと一般的に使用者が不快感を抱く就寝時や起床時などでは、視覚暖房部を停止させて安らかに就寝や起床ができることになり、また就寝時や起床時等では、一般的に使用者が機器の運転確認を必要としないときでもあり、効率的である。
【００２６】
請求項４記載に係る発明は、請求項１〜３のいずれか１項に記載の温風暖房装置にあって、制御手段は、温風暖房部がタイマー運転の選択状態にある場合は、温風暖房制御部の動作に連動する視覚暖房制御部の連動を解除し、視覚暖房制御部はＯＦＦ状態とするもので、温風暖房装置がタイマー運転により、例えば一定時間だけの暖房運転後に停止、または一定時間後に自動的に暖房運転に入る状態では、視覚暖房制御部は温風暖房制御部との連動が解除されて動作しなくなる。従って、視覚暖房部が明るいと、一般的に使用者が不快感を抱く就寝時や起床時などでは、視覚暖房部を停止させて安らかに就寝や起床ができることになり、また就寝時や起床時等では、一般的に使用者が機器の運転確認を必要としないときでもあり、効率的である。
【００２７】
請求項５記載に係る発明は、請求項１〜４のいずれか１項に記載の温風暖房装置にあって、視覚暖房制御部は、温風暖房制御部で制御するバーナの燃焼量が一定の安定した状態の場合、発光体への通電数および通電量を、前記バーナの燃焼量に比例した一定値に安定させ、第二の対流用ファンの回転数は、前記バーナの燃焼量に比例した一定値を中心にして、一定の変動幅と変動サイクルを有した制御を行うようにしたものである。
【００２８】
上記実施の形態によると、バーナの燃焼量が安定すると、視覚暖房制御部により第二の対流用ファンの回転数がある一定の変動幅と変動サイクルを持った可変となり、一方の発光体の通電数および通電量が一定状態に関わらず、視覚暖房像形成体、例えば複数のリボン状反射部材はある変動した揺らぎ状態をつくり、複数の発光体からの発光をランダムに遮ることで、機器前面から見える発光状態を、より実際の炎のように揺らいで見せることが可能になる。
【００２９】
請求項６記載に係る発明は、請求項１〜４のいずれか１項に記載の温風暖房装置にあって、視覚暖房制御部は、温風暖房制御部で制御するバーナの燃焼量が一定の安定した状態の場合、第二の対流用ファンの回転数を、前記バーナの燃焼量に比例した一定値に安定させ、複数の発光体への通電数および通電量は、前記バーナの燃焼量に比例した一定値を中心にして、一定の変動幅と変動サイクルを有した制御を行うようにしたものである。
【００３０】
上記実施の形態によると、バーナの燃焼量が安定すると、視覚暖房制御部により発光体の通電数および通電量が一定の変動幅と変動サイクルを持った可変となり、一方の第二の対流用ファンの回転数が一定状態による視覚暖房像形成体、例えば複数のリボン状反射部材が一定の揺らぎ状態でありながら、複数の発光体からの発光で揺らぎを生じることになり、機器前面から見える発光状態を、より実際の炎のように揺らいで見せることが可能になる。
【００３１】
【実施例】
以下、本発明の温風暖房装置の実施例について図１〜図７に基づき説明する。
【００３２】
（実施例１）
図１は、本発明の実施例１における温風暖房装置の概略の正面断面図で、図２は同じく概略の側面断面図で、図３は同じく温風暖房装置の制御ブロック図である。
【００３３】
図１において、１はバーナで、供給されたガスの燃焼を行う。２はバーナ１の燃焼により発生した燃焼ガスと空気を混合する燃焼室である。４はバーナ１の下方に設けた第一の対流用ファンで、本体ケース６の背面に設けた集塵用の網目状の対流用フィルター８を介して空気を吸引し、かつ前記燃焼ガスと空気の混合した温風３を送出するものである。第一の対流用ファン４の下流側には、本体ケース６の前面下部に位置して温風３を導くルーバー５を取り付けた温風吹出し口７が本体ケース６の幅いっぱいに設けてある。温風吹出し口７には、燃焼室２から流出した燃焼ガスと空気の混合気である温風３を案内する温風ガイド７ａを接続している。以上の構成で以って温風暖房部９を形成している。
【００３４】
１１は温風吹出し口の上部に位置する本体ケース６の前面部分と温風ガイド７ａに囲まれた燃焼室２の前部との間に配設した視覚暖房ケースで、その後面は燃焼室２と一定の空間を残して温度の高い燃焼室２との遮熱仕切りをなし、前面は常には内部構造物が見えなく、後面に沿って収納した通電により発光するＬＥＤ等の複数の発光体１０が発光すると視覚暖房像が映る半透光性部材の前面板１２で構成し、前面板１２が本体ケース６の前面を構成している。
【００３５】
視覚暖房ケース１１は、温風吹出し口７を除く本体ケース６の広範囲な前面の全体に配置してあり、発光体１０以外に、発光体１０の前方に間隔を有し、かつ上下の端が固定されて空気流を受けると左右に揺らぎ、かつ発光体１０の光を受けて反射する、例えば複数の布製や樹脂ビニール製のリボン状反射部材等の視覚暖房像形成体１６と、前面板１２の下に設けた吸気孔１２ａより温風３以外の空気を吸引し、前面板１２の上に設けた排気孔１２ｂより視覚暖房ケース１１外に排出して視覚暖房ケース１１内の視覚暖房像形成体１６と発光体１０の間に空気流を生じさせ視覚暖房像形成体１６を左右に揺るがす第二の対流用ファン１４を収納している。以上の構成で以って視覚暖房部１３を形成している。第二の対流用ファン１４は、駆動用モーター１５を有し、また吐出口１７近傍には、視覚暖房像形成体１６の下端が固定されている。
【００３６】
１８はマイクロコンピュータおよびその周辺回路からなる制御手段で、温風暖房部９の運転、停止と暖房能力等の制御および視覚暖房部１３の制御を行なうもので、制御基板１８ａ、１８ｂに分けて設けている。
【００３７】
すなわち、制御手段１８はバーナ１へ供給する燃料の量と第一の対流用ファン４の回転数で定まる燃焼量（例えば、強、中、弱）を制御する温風暖房制御部２５と、複数の発光体１０を発光させる制御および第二の対流用ファン１４の回転数の制御を行う視覚暖房制御部２６と、温風暖房制御部２５と視覚暖房制御部２６の関連を記憶し、それぞれの制御部に関連信号を送る記憶制御部２７を備え、そして、視覚暖房制御部２６を温風暖房制御部２５に連動させ、複数の発光体１０への通電回数と通電量、および第二の対流用ファン１４の回転数を前記燃焼量に比例して可変させる制御にしたものである。
【００３８】
従って、上記した制御を行なうために制御手段１８は、次に説明する制御シーケンスを実行するプログラムを格納しているものである。運転スイッチ２４がＯＮすると、温風暖房制御部２５が制御し始め、電磁弁１９、ガス比例弁２０、第一の対流用ファン４を駆動する第一の駆動用モーター２８を駆動させ、バーナ１へガスを供給し、点火プラグ２３の放電で点火して燃焼を開始する。同時に燃焼が開始したことを記憶した記憶制御部２７は、視覚暖房制御部２６へ信号を送り、発光体１０、第二の対流用ファン１４を駆動する第二の駆動用モーター１５を駆動させる。さらに、記憶制御部２７は、温風暖房制御部２５の制御状態を記憶判断し、予め定められたバーナ１の燃焼状態に対応した視覚暖房状態を作り出すよう、視覚暖房制御部２６に信号を送ることで、当該機器の温風暖房状態と連動した視覚暖房状態を作りだすことができるようにしてある。このように当該機器の温風暖房部９と視覚暖房部１３が駆動し運転を始めると、室温を室温センサー２９で検知し、制御基板１８ｂ上にある室温設定スイッチ３０で設定した設定温度になるよう、温風暖房制御部２５を介しバーナ１の燃焼量を可変する。
【００３９】
また、制御手段１８はバーナ１に燃料を供給する電磁弁１９および燃料量を制御するガス比例弁２０、第一の対流用ファン４を駆動させる第一の駆動用モーター２８、発光体１０、第二の対流用ファン１４を駆動させる第二の駆動用モーター１５と電気的に接続し、各部品の制御をしている。また、これ以外にも点火プラグ２３、運転スイッチ２４、室温センサー２９、室温設定スイッチ３０が制御手段１８に接続している。当該機器の運転をＯＮ・ＯＦＦする運転スイッチ２４は、制御基板１８ｂに設けられている。図中、２１はガスの供給パイプ、２２はバーナ１にガスを噴出するノズルである。
【００４０】
以上のように構成された温風暖房装置について、以下その動作と作用効果について説明する。運転スイッチ２４をＯＮすると、制御手段１８の温風暖房制御部２５により制御されてガスが電磁弁１９を通り、ガス比例弁２０により供給量を制御され、供給パイプ２１を介してノズル２２よりバーナ１に供給され、バーナ１近傍に設けられた点火プラグ２３の放電により着火して燃焼を行う。その燃焼により発生する高温の燃焼ガスと、燃焼室２の燃焼風路内で対流用フィルター８を通過した対流用空気が混合され、適度な温度となった混合空気が第一の対流用ファン４により、本体ケース６の前面下部の温風吹出し口７から温風３になって送出され、この循環により居住室の暖房が行われる。
【００４１】
また、上記暖房運転開始と同時に、これに連動した視覚暖房制御部２６の制御により、発光体１０の通電を行い発光させ、かつ第二の駆動用モーター１５の駆動により第二の対流用ファン１４の運転を行い、第二の対流用ファン１４の吐出口１７から上方に向って空気が排出され、その空気流で吐出口１７近傍に固定された複数のリボン状反射部材からなる視覚暖房像形成体１６が左右に揺れるランダムな動作を行い、結果として下から上に揺らぎながら吹き上がる。一方、このような視覚暖房像形成体１６の後方からは発光体１０の発光が照射され、その発光が視覚暖房像形成体１６の揺らぎにより遮られる瞬間および反射される瞬間が起こり、全体として見え隠れして前面板１２に下から上に左右に揺らぎ上がる擬似炎が映ることになる。
【００４２】
以上のように本実施例では、機器の本体ケース６の前面より見た場合、発光体１０の光がランダムな左右の揺らぎをする複数の視覚暖房像形成体１６に遮断されて見え隠れし、かつその光は本体ケース６の前面板１２を介すことにより拡散され、視覚的に炎のように見せることができ、使用者に視覚で暖かさを感じさせることができる。
【００４３】
また、擬似的な炎像が映る、温風吹出し口７を除く本体ケース６の広範囲な前面を通じて遠くからでも一目で機器の運転状態が確認でき、かつ広範囲な本体ケース６の前面を、機器の不使用時には本体ケース６の内部構造物が見えないようにする機能を維持しつつ、機器の使用時には有効に利用し明確な運転表示ができる。従って、外出時などの消し忘れ防止により安全性を高めることができる。
【００４４】
また、視覚暖房部１３は視覚暖房ケース１１内に、発光体１０と、視覚暖房像形成体１６と、視覚暖房像形成体を揺らす専用の第二の対流ファン１４とが内装され、かつ第二の対流ファン１４により温度の比較的に低い空気流を生じさせるので、空気流により視覚暖房像形成体１６が炎のように左右に揺れながら光反射するだけでなく、構成簡単にして視覚暖房ケース１１内に冷却作用が得られ、温風暖房部９の前側で、かつ本体ケース６の広範囲な前面であっても温風暖房部９の熱影響に左右されず、視覚暖房感とその運転状況の表示を、極めて見やすい、温風吹出し口を除く本体ケースの広範囲な前面を有効に利用して優先的に配置することができ、かつ設計的にも自由度が得られる。

また、視覚暖房制御部２６が温風暖房制御部２５に連動し、かつ比例していることにより、視覚暖房部１３の発光量とゆらぎ度合いはバーナの燃焼量に連動し、すなわち、運転能力状態も容易に確認できる。例えば、温風暖房部９の燃焼量が最大量の場合は発光体１０も最大の明るさとし、かつ第二の対流用ファン１４の回転数も最大にして視覚暖房像形成体１６を大きく揺らぐようにする。逆に燃焼量が最小量の場合は発光体１０も最小の明るさまで低下させ、かつ第二の対流用ファン１４の回転数も最小にして視覚暖房像形成体１６の揺らぎを抑える。このようにして、擬似的な炎をより現実的に演出することができるとともに、遠くからでも一目で機器の運転状態と暖房能力が確認できる。
【００４６】
また、前面板１２はガラス板あるいは樹脂板で構成することで、半透光性部材を薄く形成でき、機器の大きさを抑制することができる。
【００４７】
また、発光体１０を複数のＬＥＤで構成することで、安価で寿命が長く消費電力を少なくできる。
【００４８】
また、前面板１２は外部から内部の様子がほとんど確認できない程度のスモーク性を有しているため、内部の発光体１０、複数の視覚暖房像形成体１６、第二の対流用ファン１４そのものを確認できないので、本体ケース６の前面は温風暖房装置として何ら支障なく構成できる。
【００４９】
また、視覚暖房ケース１１は発光体１０と燃焼室２を仕切り、発光体１０を収納しているので、後面の表面に反射体を設けるか、または反射しやすい加工を施すことにより、発光体１０の発光作用を高められ、輝度とランダム性の増加が得られて視覚暖房作用と運転等の表示作用を高めることができる。
【００５０】
また、視覚暖房ケース１１は、燃焼室２とは空間を有して配置しているため、燃焼に必要な対流用空気は温風ガイド７ａに案内されて、この間を通過するように確保され、温風暖房部９への影響はなく良好な燃焼を維持することができ、かつ燃焼により発生する熱は、視覚暖房ケース１１の後面の遮熱仕切り作用により遮断され、発光体１０の温度上昇も防止できる。

（実施例２）
図４は本発明の実施例２における温風暖房装置の制御ブロック図である。本実施例は、温風暖房の動作に連動する視覚暖房の動作を停止させるかどうかを選択できるように構成した点で実施例１の発明と異なり、図１、図２を利用し実施例１と同一構成並びに作用効果を奏する部分には同じ符号を付して詳細な説明を省略し、異なるところを中心に説明する。
【００５２】
制御手段１８は、視覚暖房部１３の動作を、温風暖房部９の動作に連動させるか、停止させるかを選択できるようにするため、温風暖房制御部２５と視覚暖房制御部２６との連動の有無を選択する選択スイッチ３１を接続したもので、図２に示す制御基板１８ｂの運転スイッチ２４とは独立して設けている。従って、制御手段１８は選択スイッチの作動状態、または停止状態の信号を取り込んで記憶制御部２７からの信号のうち、視覚暖房制御部２６への信号を遮断、または入れるようにする制御シーケンスを実行するプログラムを格納している。
【００５３】
上記実施例において、選択スイッチ３１を押して作動の状態を選択すると、制御手段１８の記憶制御部２７からの信号のうち、視覚暖房制御部２６への信号を遮断し、例えば、運転スイッチ２４がＯＮ状態の場合は、温風暖房制御部２５による温風暖房運転だけが制御され、視覚暖房制御部２６による視覚暖房部１３の制御は停止され、発光体１０や第二の駆動用モーター１５の動作は行われず、視覚暖房部１３は発光しないのである。
【００５４】
従って、当該機器である温風暖房装置は選択スイッチ３１を作動状態にすると、温風暖房運転中は視覚暖房制御部２６による視覚暖房部１３の動作が停止しているため、発光による視覚暖房と表示作用がなくなり、温風暖房装置の使用状態や環境および使用者の好みなどにより自由に選択して使用することができる。
【００５５】
例えば、視覚暖房部１３が明るいと一般的に使用者が不快感を抱く就寝時や起床時などでは、視覚暖房部を停止させて安らかに就寝や起床ができるとともに、就寝時や起床時等では、一般的に使用者が機器の運転確認を必要としないときでもあり、効率的にできる。
【００５６】
なお、本実施例では選択スイッチ３１を押し下げて作動状態にする選択で視覚暖房制御部２６による視覚暖房部１３の動作を停止させているので、これを解除するには再度、選択スイッチ３１を押し下げて選択無しの元の状態にすることで再び視覚暖房制御部２６の動作を温風暖房制御部２５の動作に連動させるものである。
【００５７】
また、選択スイッチ３１で視覚暖房制御部２６による視覚暖房部１３の動作を停止させているのを、選択無しの元の状態にするには、選択スイッチ３１の選択と同時に動作したタイマにより、一定時間後に選択スイッチ３１の選択が解除され、その時に温風暖房部９が動作している時は自動的に視覚暖房制御部２６が連動して視覚暖房部１３が動作するようにしても良い。
【００５８】
（実施例３）
図５は本発明の実施例３における温風暖房装置の制御ブロック図である。本実施例は、所定時間継続してタイマーによる温風暖房運転をしている時は、温風暖房の動作に連動する視覚暖房の動作を停止させるように構成した点で実施例１および実施例２の発明と異なり、図１、図２を利用し実施例１と同一構成並びに作用効果を奏する部分には同じ符号を付して詳細な説明を省略し、異なるところを中心に説明する。
【００５９】
３２は図５に示す制御基板１８ａに設け、温風暖房部９の運転をタイマーにより所定時間継続した後に自動停止するようにする所定時間後運転停止設定スイッチとしての、おやすみ運転スイッチで、制御手段１８に接続している。従って、制御手段１８は、おやすみタイマー機能を備え、おやすみ運転スイッチ３２の作動状態、または停止状態の信号を取り込んで記憶制御部２７からの信号のうち、おやすみ運転スイッチ３２の作動状態時には視覚暖房制御部２６への信号を遮断、また、おやすみ運転スイッチ３２の停止状態時には信号を入れるようにする制御シーケンスを実行するプログラムを格納している。
【００６０】
上記実施例において、おやすみ運転スイッチ３２を選択すると、制御手段１８の記憶制御部２７からの信号のうち、視覚暖房制御部２６への信号を遮断し、例えば、おやすみ運転スイッチ３２がＯＮ状態の場合は、温風暖房制御部２５のみの暖房運転だけが制御され、視覚暖房制御部２６の制御による視覚暖房部１３の動作は停止され、発光体１０や第二の駆動用モーター１５の動作は行わないものである。
【００６１】
従って、温風暖房装置はおやすみ運転スイッチ３２を作動状態にすると、温風暖房運転中は視覚暖房制御部２６の制御による視覚暖房部１３の動作が停止しているので、視覚暖房部１３が明るいと一般的に使用者が不快感を抱く就寝時や起床時などでは、視覚暖房部１３が停止しているから、安らかに就寝や起床ができるとともに、就寝時や起床時等では、一般的に使用者が温風暖房装置の運転確認を必要としないときでもあり、効率的にできる。
【００６２】
なお本実施例では、おやすみ運転スイッチ３２の設定で温風暖房運転に関係なく、視覚暖房制御部２６による視覚暖房部１３の動作を所定時間のみ停止させているので、所定時間継続後であるタイマーの設定時間終了後には自動的におやすみ運転スイッチ３２の設定が解除されるようにしてある。
【００６３】
また、本実施例の制御手段１８では上記したように、おやすみタイマー機能を備えているが、さらに、おはようタイマー機能を備えた場合において制御手段１８は、使用者の起床前に自動起動して温風暖房運転に入り部屋を暖房するために、タイマーを使用して所定時間後運転起動設定スイッチ（図示せず）の作動状態、または停止状態の信号を取り込んで記憶制御部２７からの信号のうち、所定時間後運転起動設定スイッチの設定時間の経過後に自動的に温風暖房運転に入ると、これに連動して視覚暖房制御部２６へ信号が入り視覚暖房部１３が動作し、また所定時間後運転起動設定スイッチの停止、つまり設定されていない、実施例１で説明したように通常の使用状態では温風暖房部９の動作に連動して視覚暖房部１３が動作するように視覚暖房制御部２６へ信号が入るようにする制御シーケンスを実行するプログラムを格納するものである。ただ、この場合には使用者の起床前に温風暖房部９が自動的に立ちあがると、それと同時に視覚暖房部１３が発光するので、発光が就寝中の使用者の視野に入り、目覚めが悪いと感じる場合と目覚ましになると感じる場合が考えられ、適宜選択すればよいことである。

【００６６】
上記実施例において、温風暖房装置は図６（ｂ）に示すように、制御手段１８の温風暖房制御部２５によりバーナ１の燃焼量が強・中・弱と能力変更する際、これに連動した視覚暖房制御部２６により視覚暖房部１３の発光体１０の通電量も、ある一定量にて多・中・少と同期変化する。そして、視覚暖房部１３の第二の対流用ファン１４の回転数も、バーナ１の燃焼量の変化に多・中・少と同期変化するとともに、さらにある各一定値を中心にＴなる変動幅とＳなる変動サイクル（周期）を以って常に変化するのである。
【００６７】
従って、強・中・弱の各暖房能力に応じた多・中・少の一定値の発光体１０の発光度合いでも、第二の対流用ファン１４からの吐出空気量が周期的に変動し、これにより複数の視覚暖房像形成体１６の揺らぎも、ある周期を有して変化するため、この周期を有して揺れる視覚暖房像形成体１６により発光が見え隠れして視覚的に炎のようにみせることができ、特に発光体の多・中・少の一定値の発光体１０の発光度合いでも、視覚暖房像形成体１６の周期変化で使用者に視覚暖房と暖房能力表示を確実に感じさせることができる。

TECHNICAL FIELD OF THE INVENTION
TECHNICAL FIELD The present invention relates to a hot air heating device that blows out hot air to heat a room.
[0002]
[Prior art]
Conventionally, as this type of hot air heater, as shown in FIG. 8, for example, a display device is provided so as to protrude, and hot air using kerosene having a configuration in which an operation state can be confirmed by light emission from the front, both side surfaces, and the upper surface of the device. There is a heater.
[0003]
In FIG. 8, reference numeral 101 denotes a hot air heater main body, 102 denotes an operation unit such as an operation provided at the upper part on the front surface, 103 denotes a hot air outlet to which a louver 104 for blowing hot air is attached, and 105 denotes a hot air heater main body. A convection fan attached to the air intake 106 on the back of 101, a burner 107 projecting from the burner head 108, and a combustion cylinder 109 surrounding the burner head 108 and forming a combustion space.
[0004]
Reference numeral 110 denotes an upper front portion of the hot air heater main body 101 between the operation unit 102 and the hot air outlet 103, and a color display unit provided at the center of the width thereof, and a light emitting unit 111 for emitting two colors of red and green. And a diffusion lens 112 for diffusing the light of the light emitting unit 111 around the color display unit 110 (for example, see Patent Document 1).
[0005]
However, in the conventional configuration, the diffusion lens 112 of the color display unit 110 as a display is provided so as to protrude, and the operation state can be confirmed by light emission from the front, both side surfaces, and the top surface of the device. Since the display 101 is located at a certain height at the upper portion of the front surface and at the center in the width direction, the display is small, and there is a problem that the operation state cannot be clearly confirmed from a distance. In particular, in the case of a hot air heater that uses gas as fuel, the operating noise during combustion is quieter, and in the case of weak combustion, the noise is as low as 22 dB, making it difficult to see at a glance whether or not combustion is occurring. It is conceivable that it will be left unattended. Further, most of the front surface of the hot air heater main body 101 other than the position where the display and the hot air outlet 103 are located is the same as the front surface of the main body case, except for the function of making the internal structure invisible as a result. It was a structure that was never done.

The front plate 12 is a semi-translucent member on which a visual heating image is projected when light is emitted. The front plate 12 forms the front surface of the main body case 6.
[0035]
The visual heating case 11 is disposed over the entire wide front surface of the main body case 6 except for the hot air outlet 7, and has an interval in front of the luminous body 10 in addition to the luminous body 10, and has upper and lower ends. A visual heating image forming body 16, such as a plurality of cloth or resin vinyl ribbon reflecting members, which fluctuates left and right when fixed and receives an air flow, and which receives and reflects light from the light emitting body 10, and a front plate 12. Air other than the warm air 3 is sucked through an air inlet 12a provided under the front panel 12 and discharged out of the visual heating case 11 through an exhaust hole 12b provided on the front plate 12 to form a visual heating image in the visual heating case 11. A second convection fan 14 for generating an airflow between the body 16 and the light emitting body 10 to shake the visual heating image forming body 16 left and right is housed. With the above configuration, the visual heating unit 13 is formed. The second convection fan 14 has a drive motor 15, and the lower end of the visual heating image forming body 16 is fixed near the discharge port 17.
[0036]
Reference numeral 18 denotes a control unit including a microcomputer and its peripheral circuits, which controls the operation, stop, and heating capacity of the hot air heating unit 9 and controls the visual heating unit 13, and is provided separately on control boards 18a and 18b. ing.
[0037]
That is, the control means 18 includes a hot air heating control unit 25 that controls a combustion amount (for example, strong, medium, or weak) determined by the amount of fuel supplied to the burner 1 and the rotation speed of the first convection fan 4; The visual heating control unit 26 that controls the light emission of the light emitter 10 and controls the rotation speed of the second convection fan 14, and stores the relationship between the hot air heating control unit 25 and the visual heating control unit 26, and stores The storage unit 27 that sends a related signal to the control unit is provided, and the visual heating control unit 26 is linked to the hot air heating control unit 25, and the number of times and the amount of current to the plurality of light emitters 10, and the second convection In this control, the rotation speed of the fan 14 is varied in proportion to the combustion amount.
[0038]
Therefore, the control means 18 stores a program for executing a control sequence described below in order to perform the above control. When the operation switch 24 is turned on, the hot air heating control unit 25 starts to control, and drives the solenoid valve 19, the gas proportional valve 20, the first drive motor 28 for driving the first convection fan 4, and the burner 1 The gas is supplied to the ignition plug 23 to ignite by the discharge of the ignition plug 23 to start combustion. At the same time, the storage control unit 27 that has stored the fact that combustion has started sends a signal to the visual heating control unit 26 to drive the luminous body 10 and the second drive motor 15 that drives the second convection fan 14. Further, the storage control unit 27 stores and determines the control state of the hot air heating control unit 25, and sends a signal to the visual heating control unit 26 to create a visual heating state corresponding to a predetermined combustion state of the burner 1. This makes it possible to create a visual heating state linked to the hot air heating state of the device. As described above, when the hot air heating unit 9 and the visual heating unit 13 of the device are driven and started to operate, the room temperature is detected by the room temperature sensor 29, and the temperature becomes the set temperature set by the room temperature setting switch 30 on the control board 18b. Thus, the combustion amount of the burner 1 is varied via the hot air heating control unit 25.
[0039]
The control means 18 includes an electromagnetic valve 19 for supplying fuel to the burner 1, a gas proportional valve 20 for controlling the amount of fuel, a first drive motor 28 for driving the first convection fan 4, a light emitter 10, It is electrically connected to a second drive motor 15 for driving the two convection fans 14, and controls each component. In addition, an ignition plug 23, an operation switch 24, a room temperature sensor 29, and a room temperature setting switch 30 are connected to the control means 18. An operation switch 24 for turning ON / OFF the operation of the device is provided on the control board 18b. In the figure, reference numeral 21 denotes a gas supply pipe, and reference numeral 22 denotes a nozzle for ejecting gas to the burner 1.
[0040]
The operation and effect of the hot air heating device configured as described above will be described below. When the operation switch 24 is turned on, the gas is controlled by the hot air heating control unit 25 of the control means 18, the gas passes through the solenoid valve 19, the supply amount is controlled by the gas proportional valve 20, and the gas is supplied from the nozzle 22 through the supply pipe 21. 1 and is ignited by the discharge of a spark plug 23 provided near the burner 1 to perform combustion. The high-temperature combustion gas generated by the combustion is mixed with convection air that has passed through the convection filter 8 in the combustion air passage of the combustion chamber 2, and the mixed air having an appropriate temperature is supplied to the first convection fan 4. As a result, the warm air 3 is sent out from the warm air outlet 7 at the lower front part of the main body case 6, and the circulation heats the living room.
[0041]
Simultaneously with the start of the heating operation, the luminous body 10 is energized to emit light under the control of the visual heating control unit 26 in conjunction therewith, and the second convection fan 14 is driven by the driving of the second drive motor 15. Is performed, air is discharged upward from the discharge port 17 of the second convection fan 14, and the air flow forms a visual heating image formed by a plurality of ribbon-shaped reflecting members fixed near the discharge port 17 The body 16 performs a random motion of swaying left and right, and as a result, blows up while swaying from bottom to top. On the other hand, the light emission of the light emitting body 10 is emitted from behind the visual heating image forming body 16, and the moment when the light emission is interrupted and reflected by the fluctuation of the visual heating image forming body 16 occurs, and as a whole, it appears and disappears. Then, a simulated flame oscillating right and left from bottom to top is reflected on the front plate 12.
[0042]
As described above, in the present embodiment, when viewed from the front of the main body case 6 of the device, the light of the illuminant 10 is intercepted by the plurality of visual heating image forming bodies 16 that fluctuate randomly from side to side, and is visible and hidden. The light is diffused by passing through the front plate 12 of the main body case 6, and can be visually made to look like a flame, so that the user can visually feel warmth.
[0043]
In addition, the operating state of the device can be checked at a glance even from a distance through a wide front surface of the main body case 6 excluding the hot air outlet 7 where a simulated flame image is reflected. While the function of keeping the internal structure of the main body case 6 invisible when not in use is maintained, when the device is used, it can be effectively used and a clear operation display can be made. Therefore, safety can be enhanced by preventing forgetting to turn off when going out.
[0044]
Further, the visual heating unit 13 includes a luminous body 10, a visual heating image forming body 16, and a second convection fan 14 dedicated to swing the visual heating image forming body inside the visual heating case 11, and Generates a relatively low temperature air flow by the convection fan 14, so that the visual heating image forming body 16 not only reflects light while swaying left and right like a flame due to the air flow, but also has a simple configuration to achieve a visual heating case. 11, a cooling effect is obtained, and even in the front side of the hot air heating unit 9 and even in the wide front of the main body case 6, the visual heating feeling and the operation state thereof are not affected by the thermal influence of the hot air heating unit 9. Can be preferentially arranged by effectively utilizing the wide front surface of the main body case excluding the hot air outlet, which is extremely easy to see, and the degree of freedom in design can be obtained.
[0045]
Further, since the visual heating control unit 26 is interlocked with and is proportional to the hot air heating control unit 25, the light emission amount and the fluctuation degree of the visual heating unit 13 are interlocked with the combustion amount of the burner. Can also be easily confirmed. For example, when the combustion amount of the hot air heating unit 9 is the maximum amount, the light emitting body 10 is also set to the maximum brightness, and the rotation speed of the second convection fan 14 is also maximized so that the visual heating image forming body 16 fluctuates greatly. To Conversely, when the combustion amount is the minimum amount, the light emitting body 10 is also reduced to the minimum brightness, and the rotation speed of the second convection fan 14 is also minimized to suppress the fluctuation of the visual heating image forming body 16. In this way, a pseudo flame can be produced more realistically, and the operating state and the heating capacity of the device can be confirmed at a glance even from a distance.
[0046]
Further, by forming the front plate 12 from a glass plate or a resin plate, the semi-transparent member can be formed thin, and the size of the device can be suppressed.
[0047]
Further, by configuring the light emitting body 10 with a plurality of LEDs, it is possible to reduce the power consumption with a low cost and a long life.
[0048]
Further, since the front plate 12 has a smoke property that the inside can hardly be seen from the outside, the inside light emitting body 10, the plurality of visual heating image forming bodies 16, and the second convection fan 14 itself are used. Since it cannot be confirmed, the front surface of the main body case 6 can be configured without any trouble as a hot air heating device.
[0049]
Further, since the visual heating case 11 separates the luminous body 10 from the combustion chamber 2 and accommodates the luminous body 10, the luminous body 10 is provided by providing a reflector on the rear surface or performing a process of easily reflecting the light. , The brightness and the randomness are increased, and the visual heating action and the display action such as driving can be enhanced.
[0050]
Further, since the visual heating case 11 is arranged with a space from the combustion chamber 2, convection air necessary for combustion is guided by the hot air guide 7a and secured so as to pass through the space. Good combustion can be maintained without affecting the hot air heating unit 9, and the heat generated by the combustion is cut off by the heat shielding partitioning action on the rear surface of the visual heating case 11, and the temperature of the luminous body 10 also increases. Can be prevented.
[0051]
(Example 2)
FIG. 4 is a control block diagram of the hot air heating device according to the second embodiment of the present invention. The present embodiment differs from the invention of the first embodiment in that it is configured to select whether to stop the operation of the visual heating linked to the operation of the hot air heating, and the first embodiment uses FIGS. Portions having the same configuration and operation and effect as those described above are denoted by the same reference numerals, and detailed description thereof will be omitted.
[0052]

Therefore, the control means 18 executes a control sequence for taking in the signal of the operation state or the stop state of the selection switch and cutting off or turning on the signal to the visual heating control section 26 among the signals from the storage control section 27. Program to be stored.
[0053]
In the above embodiment, when the operation state is selected by pressing the selection switch 31, the signal to the visual heating control unit 26 among the signals from the storage control unit 27 of the control unit 18 is cut off. In the state, only the hot air heating operation by the hot air heating control unit 25 is controlled, the control of the visual heating unit 13 by the visual heating control unit 26 is stopped, and the operation of the light emitting body 10 and the second drive motor 15 are performed. Is not performed, and the visual heating unit 13 does not emit light.
[0054]
Therefore, when the selection switch 31 is activated in the hot air heating device, the operation of the visual heating unit 13 by the visual heating control unit 26 is stopped during the hot air heating operation. The display function is eliminated, and the apparatus can be freely selected and used depending on the usage state, environment, and user's preference of the hot air heating apparatus.
[0055]
For example, at the time of bedtime or waking up when the user generally has discomfort when the visual heating unit 13 is bright, the visual heating unit can be stopped and sleeping or waking up can be performed safely by stopping the visual heating unit, and at the time of going to bed or waking up. In general, even when the user does not need to check the operation of the device, the operation can be efficiently performed.
[0056]
In this embodiment, since the operation of the visual heating unit 13 by the visual heating control unit 26 is stopped by selecting the operation switch 31 by pressing down the selection switch 31, the selection switch 31 is depressed again to cancel the operation. The operation of the visual heating control unit 26 is again linked to the operation of the hot air heating control unit 25 by returning to the original state without selection.
[0057]
In addition, the operation of the visual heating control unit 26 stopped by the visual heating control unit 26 by the selection switch 31 is returned to the original state without any selection. After a certain time, the selection of the selection switch 31 is canceled, and when the hot air heating unit 9 is operating at that time, the visual heating control unit 26 may be automatically linked with the visual heating unit 13 to operate.
[0058]
(Example 3)
FIG. 5 is a control block diagram of a hot air heating device in Embodiment 3 of the present invention. This embodiment is different from the first embodiment and the first embodiment in that the visual heating operation linked to the hot air heating operation is stopped when the timer is performing the hot air heating operation continuously for a predetermined time. Unlike the second embodiment, the portions having the same configuration and operation and effect as those of the first embodiment are denoted by the same reference numerals in FIGS. 1 and 2 and the detailed description thereof will be omitted, and different portions will be mainly described.
[0059]
A sleep operation switch 32 is provided on the control board 18a shown in FIG. 5 and serves as an operation stop setting switch for a predetermined time after which the operation of the hot air heating unit 9 is automatically stopped after the timer is continued for a predetermined time. 18. Therefore, the control means 18 has a good night timer function, takes in the signal of the operation state of the good night operation switch 32 or the stop state, and receives the signal from the storage control unit 27 and performs the visual heating control when the good night operation switch 32 is in the operation state. A program for executing a control sequence for shutting off a signal to the unit 26 and turning on the signal when the sleep operation switch 32 is stopped is stored.
[0060]
In the above embodiment, when the good night operation switch 32 is selected, the signal from the storage control unit 27 of the control unit 18 to the visual heating control unit 26 is shut off. For example, when the good night operation switch 32 is in the ON state, Only the heating operation of the hot air heating control unit 25 is controlled, the operation of the visual heating unit 13 under the control of the visual heating control unit 26 is stopped, and the operations of the light emitter 10 and the second drive motor 15 are performed. Not something.
[0061]
Therefore, when the warm air heating device sets the night operation switch 32 to the operating state, the operation of the visual heating unit 13 under the control of the visual heating control unit 26 is stopped during the hot air heating operation, so that the visual heating unit 13 is bright. At the time of bedtime or wake-up when the user is generally uncomfortable, the visual heating unit 13 is stopped, so that the user can go to bed or wake up in a relaxed manner. Even when the user does not need to check the operation of the hot air heating device, the operation can be performed efficiently.
[0062]
In the present embodiment, the operation of the visual heating unit 13 by the visual heating control unit 26 is stopped only for a predetermined time regardless of the hot air heating operation by setting the good night operation switch 32. After the end of the set time, the setting of the sleep operation switch 32 is automatically released.
[0063]
Further, as described above, the control means 18 of the present embodiment has the good night timer function. However, in the case where the good morning timer function is provided, the control means 18 automatically starts up before the user wakes up and warms up. In order to start the air heating operation and to heat the room, after a predetermined period of time using a timer, the operation start setting switch (not shown) is operable or stopped, and the signal from the storage controller 27 is taken out. When the warm air heating operation is automatically started after a lapse of a set time of the operation start setting switch after a predetermined time, a signal is input to the visual heating control unit 26 in conjunction with the warm air heating operation, and the visual heating unit 13 is operated. The visual heating unit 13 is operated in conjunction with the operation of the hot air heating unit 9 in the normal use state as described in the first embodiment, in which the post-operation start setting switch is stopped, that is, not set. It is for storing a program for executing a control sequence to allow the signal enters the objective Heating controller 26. However, in this case, when the warm air heating unit 9 automatically rises before the user wakes up, the visual heating unit 13 emits light at the same time, so that the light emission enters the field of view of the sleeping user, and awakening is poor. There is a case where the user feels that he / she is awake, and a case where he / she feels that he / she wakes up.
