摘要： PROBLEM TO BE SOLVED: To provide a latent heat recovery type hot water supply apparatus, surely preventing drain generated due to heat exchange from splashing outside of an exhaust part together with combustion gas through an outflow port. SOLUTION: In this latent heat recovery type hot water supply apparatus, the exhaust part 9 is formed by mounting an exhaust part structure 25 on a secondary heat exchanger 7. A deflecting member 26 is disposed in the interior of the exhaust part 9, and a dispersion plate 27 is provided in a position opposite thereto. A deflecting plate part 30 of the deflecting member 26 is substantially put in the state of hanging downward from the top face 9a side, and a gap 35 is formed between the lower end part thereof and a base 9b. Combustion gas introduced into the exhaust part 9 from the base 9b flows toward the dispersion plate 27 after passing through the gap 35 so that the flowing direction is deflected. The combustion gas is dispersed in the exhaust part 9 by collision with the dispersion plate 27, and then discharged from an exhaust port 23. COPYRIGHT: (C)2009,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a gas hot water supply apparatus, achieving accurate combustion characteristic to some degree while simple control is adopted, and exhibiting the original maximum output number even under the exhaust resistance.
SOLUTION: Increase in exhaust resistance is detected according to a change in load current value of a fan motor, and the rotating speed of the fan motor is increased by predetermined amount each. As an upper limit to an output number computed value (S11) obtained by adding an FB control number to FF control number, from the original preset maximum output number, a number obtained by multiplying the up count of the fan rotating speed by a predetermined increase number is added to the preset maximum output number to obtain an enlarged change number, and it is changed to the enlarged change number (S12-S14). On the other hand, the preset maximum flow rate value (24 L/min) which is the upper limit value to the maximum flow (S21) in control, computed based on a temperature difference between the preset hot water delivery temperature and the inlet water temperature, is maintained as it is normal without exhaust resistance (S22-S24).

摘要： PROBLEM TO BE SOLVED: To sense when an incomplete combustion that an oxygen is deficient occurs by providing a combustion temperature sensor for measuring a combustion temperature of a gas combustor, and sensing an oxygen deficiency state by a falling speed of the combustion temperature of the combustor. SOLUTION: A gas proportional valve 13 and a main solenoid valve 14 are provided at gas piping 12 for supplying gas to a gas burner 10. A burner sensor (combustion temperature sensor) 17 such as a thermistor or the like for directly sensing a combustion temperature by a thermal conduction due to a contact with a burning flame is provided at a gas burning position of the burner 10, and the combustion temperature of the burner 10 is measured more accurately than that of a flame rod or the like. An oxygen deficiency deciding unit 21 provided in a controller 19 reads a measured value (burner sensor temperature) of the sensor 17 each time a predetermined time is elapsed, calculates a falling speed of the combustion temperature of the burner 10 from the burner sensor temperature, and monitors the oxygen deficient state based on the result.
