After setting at 8, when the changeover switch 13 is set to "automatic" or "boiling", if the water temperature (hot water temperature) is below the set temperature, the ignition operation is started. For ignition, first, the closing valve 3 is opened, the pilot burner 5 is ignited, and after confirming that the pilot burner 5 is ignited, the ignition valve 4 is opened and the main burner 6 is ignited. The heat exchanger 7 is heated by the main burner 6 to boil the bath. When it is detected by the signal from the temperature sensor 2 that the set hot water temperature is reached, the ignition valve 4 and the shutoff valve 3 are closed, and the combustion is stopped. Further, when the temperature sensor 2 is out of order and is not heated, an abnormality is detected by a signal from the temperature sensor 2 and the ignition valve 4

をくり返す。First, when the changeover switch 13 is "OFF", the DC power is not transmitted and all operations are stopped. Next, when the changeover switch 13 is set to "continuous", the DC power is directly supplied to the ignition sequence circuit 11, and the main burner 7 burns. When the changeover switch 13 is set to "automatic operation",
If there is no failure in the sensor 2 from the signal from the sensor 2, the DC power is supplied to the hot water temperature detection circuit 15 via the abnormality detection circuit 14, and the signal from the sensor 2 compares the set temperature with the water temperature (hot water temperature). If the set temperature is high, the hot water temperature detection circuit 1
DC power is supplied to the ignition sequence circuit 11 via 5 and the main burner 7 burns. Then, the signal that the ignition valve 4 is opened activates the forced combustion circuit 16 for detection of the empty heating, and the DC power source is given to the ignition sequence circuit 11 through the forced combustion circuit for a predetermined time to perform combusted combustion.
In the meantime, if there is no heating by the signal from the temperature sensor 2, the abnormality detection circuit 14 is activated and the DC power supply is the abnormality detection circuit 1
It stops at 4 and all movement stops. If normal, if the set temperature is higher than the hot water temperature after the operation of the forced combustion circuit 16 is completed, the DC power supply is given to the ignition sequence circuit 11 via the hot water temperature detection circuit 15 and burns until the hot water temperature reaches the set temperature. continue. If the set temperature is lower than the hot water temperature, the DC power supply stops at the hot water temperature detection circuit 15 and the combustion stops. Next, when the hot water temperature becomes equal to or lower than the set temperature, the DC power source is supplied to the ignition sequence circuit 11 via the hot water temperature detection circuit, and the above operation is repeated.

Not only does the bath water boil to the set temperature, but even if the bath water radiates heat and the hot water temperature drops after a lapse of time, the main burner 6 again heats the bath water to the set temperature according to the instruction of the ignition sequence circuit 11. It is easy to use because you can bathe in hot water at the set temperature at any time. Also, if you want to stop both heating operations after boiling, you can prevent waste of energy by putting the changeover switch 13 in "boiling", and also use "continuous" heating operation. You can also select the driving that suits your usage.
