摘要： PROBLEM TO BE SOLVED: To provide a CO gas detecting device to effect correction of a 0-point reference value right after installation of a gas apparatus with high precision by considering the influence of temperature after combustion. SOLUTION: An initial correction means 2a-6 performs initial correction of a 0-point reference value in a way that, not in a combustion state according to a start of operation of the gas apparatus and in a state that a detecting element is heated to a detecting temperature, the detecting output of a CO detector is stored as a fresh 0-point reference value at a 0-point reference value memory means instead of a 0-point reference value before the fresh 0-point reference value to execute initial correction of the 0-point reference value. A first combustion correcting means 2a-7 executes first combustion correction of the 0-point reference value such that the detecting output of the CO detector is stored as a fresh 0-point reference value instead of a 0-point reference value before the fresh 0-point reference value at the 0-point reference value memory means at a point of time when any influence is not exercised on correction of the 0-point reference value by temperature generated by combustion after completion of combustion during completion of the first time combustion of the gas apparatus after initial correction.

摘要： PROBLEM TO BE SOLVED: To provide a CO gas detecting device to perform correction operation of a 0-point reference value without modifying an existing gas hot water supply apparatus and inviting remarkable cost increase. SOLUTION: An initial correction means 2a-6 causes a heating control means to control heating to the detecting temperature of a detecting element by a heating means according to input of an operation starting signal to an operation starting signal input means 2a-3 and cause a combustion control signal output means 2a-4 to output a combustion control signal to prohibit combustion of the gas hot water supply apparatus. In a state that the gas hot water supply apparatus is not a combustion state but the detecting element is heated to a detecting temperature, initial correction of the 0-point reference value is executed such that the detecting output of a CO detector is stored as a fresh 0-point reference value at a 0-point reference value memory means instead of a 0-point reference value before the fresh 0-point reference value. Thereafter, the output of a combustion control signal by the combustion control signal means is completed to bring the gas hot water supply apparatus into a combustion state.

It is decided by a deciding means 2a-1 that a detecting signal outputted by the CO detector exceeds a predetermined given value based on given concentration of CO gas. An alarming means 2a-2 performs an alarm when a total value of times decided by the deciding means during a past specified period exceeds a predetermined value.

摘要： PROBLEM TO BE SOLVED: To provide a gas detector for outputting sensor output vsen having cancelled the effect due to a peripheral temperature without causing the rise in the heat values of both of the platinum coil Rs of a detection element 2 and the platinum coil Rs of a comparison element 3 accompanied by a temperature rise.
SOLUTION: A constant voltage source cv1 feeds constant voltage to the detection element 2 and the comparison element 3, and a sensor circuit 4 outputs the difference Vs-Vr, which is calculated by subtracting the voltage Vr across both terminals of the comparison element 3 from the voltage Vs across both terminals of the detection element 2 as the sensor output vsen. A fixed resistor Rcs is connected to the detection element 2 and the comparison element 3 in series so that sensor current i flows to the detection element 2 and the comparison element 3. A temperature correcting circuit 5 generates the temperature correcting voltage vc1 corresponding to the voltage Vcs across both terminals of the fixed resistor Rcs to add the generated voltage vc1 to the sensor output vsen to thereby correct the variation component corresponding to a rise and fall in the peripheral temperature of the sensor output vsen.

摘要： PROBLEM TO BE SOLVED: To distinguish whether imperfect combustion is temporary or caused by aged degradation. SOLUTION: A carbon monoxide sensor 11 for detecting imperfect combustion of a hot-water supply system 1 is provided in a stack adaptor 3 to be combined with the exhaust stack of the hot-water supply system 1. When determination means 21 detects imperfect combustion based on carbon monoxide concentration detected by the carbon monoxide sensor 11, a shut-off valve 13 is closed to stop the operation of the hot-water supply system 1. Counting means 25 counts the frequency of operation shutdown, and when the count reaches a predetermined number of times, the hot-water supply system 1 is prohibited to resume operation. When the operation of the hot-water supply system 1 is resumed after it is stopped due to imperfect combustion, however, if running time integrated by running-time integrating means 28 exceeds a predetermined time, reset means 29 resets the count of the counting means 25 regarding that temporary imperfect combustion has occurred.
