使い勝手上、大変不便は手段を用いていた。 Generally, hot water boilers require several hours of combustion time to boil hot water, and once the target water temperature is reached, combustion stops and the combustion indicator lamp turns off.
If the appliance is in a normal condition, but if an abnormal condition occurs in the combustion system such as mis-ignition or misfire, or a dry firing condition due to a water outage, the operation will be stopped and an abnormality indicator lamp will be turned on, and a safety device using a bimetal switch will be used. The system uses a means to electrically stop operation and mechanically pop out a button to indicate an abnormality in the equipment.A display system is provided mainly for the purpose of taking measures in the event of an abnormality. In terms of ease of use, the system used a method that was extremely inconvenient in terms of ease of use, as it postponed the display of the boiling water status until later.

Reed relay switch as a switch means for detecting the presence or absence of a body, 15.

点灯する。 When the operation switch 3 is turned on, if the hot water temperature detected by the hot water temperature thermistor 12 is lower than the target temperature set by the variable resistor 13, the output terminal of the comparator 17 becomes "high". The transistor 22 drives the relay 23 to turn on the combustion motor, and starts charging the electrolytic capacitor 32 via the resistor 30, and the combustion control sequence circuit 36 operates to start combustion.
The combustion lamp 5 is turned on. When the hot water temperature reaches the target, the output of the comparator 17 is reversed to "low", releasing the charging voltage of the electrolytic capacitor 32,
Since the combustion control sequence circuit 36 is stopped and the transistor 22 is turned off, the transistor 27 is turned on and the boiling lamp 28 is turned on.

continues and combustion does not start. As a result, neither the combustion lamp 5 nor the boiling lamp 28 lights up.
If there is an abnormality in the combustion system and mis-ignition or pre-ignition occurs, the combustion lamp 5 will not light up because no combustion detection signal will be generated. Further, since the hot water has not reached the target temperature, the output 17 of the comparator continues to be "high" and the boiling lamp 28 does not light up.

ねることが出来るものである。 Therefore, according to the present invention, if the appliance is burning during normal operation, the combustion lamp 5 lights up, and when hot water boils and combustion stops, the boiling lamp 2 lights up.
8 lights up, and the combustion lamp 5 goes out. When an abnormality occurs, neither the combustion lamp 5 nor the boiling lamp 28 will turn on, and the status of the appliance can be easily determined by combining multiple lamps, improving usability and displaying abnormal conditions. It can serve as both.
