The water is automatically supplied to the heat exchanger, the main burner is ignited, and the hot water generated in the heat exchanger is supplied. Further, by adjusting the gas supply amount to the main burner during combustion, the combustion amount of the main burner is adjusted to adjust the hot water supply temperature. Moreover, such a water heater can supply water to a plurality of places such as a bathtub, a kitchen, and a washroom by itself.

ようにしたものがある。Each time the water heater is used, the user must ignite or extinguish the pilot burner each time.
The operation is troublesome. Therefore, in recent years, in order to improve the operability and convenience of the water heater, an electronic unit is incorporated in the water heater, and automatic water supply to the heat exchanger, automatic gas supply to the main burner, automatic ignition of the main burner, etc. In the meantime, a controller for remotely operating the electronic unit is provided in the room, and by operating the controller, the water heater is remotely operated, and the bathtub is automatically filled with water, boiled, and kept warm. Furthermore, there are some that allow reserved driving and the like.

ーナの燃焼不良を検出することができない。All of the conventional water heaters have a safety device incorporated therein to prevent the burner from disappearing and the boiler being heated. However, it is necessary to monitor changes in combustion specifications of the air supply / exhaust system. Therefore, the combustion failure of the burner due to the variation of the combustion specifications cannot be detected.

ともある。Combustion specifications of the supply / exhaust system include exhaust pressure in the combustion chamber, supply pressure, exhaust temperature, and the like, and the influence of changes in these combustion specifications on combustion cannot be ignored in automatic operation. . For example, a bird makes a nest in the exhaust stack,
If foreign matter enters or the exhaust stack is clogged, the exhaust pressure becomes abnormally high, which may cause backfire.
On the contrary, if a hole is formed in the exhaust stack or if the exhaust stack is disengaged, the exhaust gas leaks into the room. In addition, the air supply port may be blocked and insufficient air supply may not be performed.

囲を予めセットすることができない。In order to solve such a problem, it is sufficient to monitor the fluctuation of combustion specifications during hot water supply. The combustion specifications depend on the environment of the place where the water heater is installed and the exhaust gas connected. It depends on the length of the cylinder, etc. and is not always constant. Therefore, the variation range of the combustion specifications cannot be set in advance in the electronic unit incorporated in the water heater.

That is, when the exhaust pressure changes, the hot water supply fan (17) or the bath fan (3
The load of 2) also changes and the current changes. The safety device is controlled by detecting this change in current. To set the initial value, after installing the water heater (1), operate it once and measure the current fluctuation of the electric motor within the safe combustion range,
The measured value is stored in the electronic unit (44) as an initial value.

なる。According to the present invention, after the combustor is installed indoors, the combustor is operated to operate from the minimum safe combustion to the maximum safe combustion, and the combustion of the supply / exhaust gas in the combustion chamber at that time is performed. When the measured data of the specifications are stored in the electronic unit as initial values, the measured data of the combustion specifications of the supply / exhaust gas in the combustion chamber during combustion are transmitted to the electronic unit, and the measured data deviates from the initial values stored in advance. Since the safety device is activated to shut off the gas and stop the combustion, the control becomes accurate.
