本願第2発明(請求項3の発明)は、本願第1発明(請求項1の発明)の前記作動に加えて、燃焼正常信号カウント手段Dは、燃焼判別手段よりの燃焼正常信号を受信して、燃焼正常信号の発生時間を蓄積し、燃焼正常信号の存在時間を蓄積カウントする。 In the second invention of the present application (invention of claim 3), in addition to the operation of the first invention of the present application (invention of claim 1), the combustion normal signal counting means D receives the combustion normal signal from the combustion discrimination means. Then, the generation time of the combustion normal signal is accumulated, and the existence time of the combustion normal signal is accumulated and counted.

連続正常燃焼判別手段Eは、前記燃焼正常信号蓄積カウント手段Dよりの燃焼正常信号の時間値と、設定時間値T3(例えば、60分)とを比較して、「所定時間連続正常燃焼」を判別し、「所定時間連続正常燃焼」信号を前記燃焼異常信号カウント手段Bに送信して、燃焼異常信号カウント手段のカウント蓄積値をゼロとする。 The continuous normal combustion determination means E compares the time value of the combustion normal signal from the combustion normal signal accumulation count means D with a set time value T3 (for example, 60 minutes), and performs “predetermined time continuous normal combustion”.

なお、実施例にかいては、燃焼正常信号カウント手段Dのカウント蓄積値をゼロとする燃焼正常カウントリセット手段Fを設けたので、燃焼正常信号が連続していることが条件で、途中に燃焼異常信号が発生した場合には、燃焼異常信号発生の前後を加算して積算値T3を超えても、燃焼異常信号カウント手段のカウント蓄積値のクリヤー処理は発生しない。 In the embodiment, the combustion normal count resetting means F for setting the count accumulation value of the combustion normal signal counting means D to zero is provided, so that the combustion is performed on the condition that the combustion normal signal is continuous. When an abnormal signal is generated, the count accumulation value of the combustion abnormal signal counting means is not cleared even if the integrated value T3 is exceeded by adding before and after the occurrence of the abnormal combustion signal.

本願第3発明(請求項5の発明)は、前述の異常燃焼リセット手段Gにより、連続正常燃焼判別手段Eによる「所定時間連続正常燃焼」の判別により燃焼異常信号カウント手段Bを「カウント零」にリセットするが、燃焼異常信号の発生で、正常燃焼リセット手段Fは、燃焼正常信号カウント手段Dを「正常連続燃焼時間蓄積=0」にリセットすることで、正常燃焼を「所定時間連続」することが条件となる。
In the third invention of the present application (invention of claim 5), the abnormal combustion signal counting means B is set to “count zero” by the above-mentioned abnormal combustion resetting means G by the discrimination of “continuous normal combustion for a predetermined time” by the continuous normal combustion judging means E. However, the normal combustion reset means F resets the combustion normal signal count means D to “normal continuous combustion time accumulation = 0” to generate “normal continuous combustion” for a predetermined time. It is a condition.

本発明は、燃焼機器の連続不完全燃焼時の運転を確実に阻止することで、燃焼機器の機器不良による酸欠事故を防止し、消費者に安全な燃焼機器を提供するものであるから、燃焼機器製造産業の発展に寄与するものである。 Since the present invention reliably prevents the operation during continuous incomplete combustion of the combustion equipment, prevents an oxygen deficiency accident due to equipment failure of the combustion equipment, and provides a safe combustion equipment to the consumer. It contributes to the development of the combustion equipment manufacturing industry.
