ものである。Further, when the water heater is started with the operation switch turned on at the time of turning on the power (at the time of power recovery), a power failure occurs during hot water supply, and then, when running water is detected when power is restored, combustion may start. However, if an earthquake accompanied by a power outage occurs, if there is water flowing after power restoration, combustion may start in spite of a dangerous state, and in order to solve this problem, Flowing water detecting means for detecting the flow of water to be heated, combustion starting means for starting combustion when the flowing water detecting means detects running water with the water heater turned on, and abnormality detecting for detecting abnormality of the water heater. Means,
A memory capable of storing an ON / OFF state of the operation switch of the water heater before the power failure and capable of holding the same even during the power failure, and an operation switch ON / O stored in the memory when the power is restored.
Power recovery control means for switching to the FF state, wherein the power recovery control means turns off the operation switch of the water heater at the time of power recovery after the abnormality detection means detects an abnormality.

Even after a power outage is detected, the EEP
Even if the ROM 9 stores the operation switch ON state, since the abnormality content data is also stored in the EEPROM 9 at the same time, the water heater 1 is started in the operation switch OFF state. It is safe without starting combustion.

By doing so, the contents of the abnormality are displayed. If the contents of the abnormality are so severe that they need to be repaired by a serviceman, the operation switch 16 is operated to prevent the abnormality from being released, and the operation of the reset switch (not shown) on the board of the hot water supply control device 6 causes the abnormality to be corrected. If it can be released, a serious abnormality is not inadvertently released, and further safety can be ensured.

The operation switch OFF state data is stored in the ROM 9, and when the power is subsequently turned on (when the power is restored).
In order to read the operation switch OFF state data from the EEPROM 9, when there is any abnormality, the water heater 1 is started in the operation switch OFF state. Therefore, when there is an abnormality, the water heater 1 is started in the operation switch ON state. It is very safe without falling.

In the power recovery control sequence, the EEPROM 9
It is only necessary to be able to start the water heater 1 in the operation switch OFF state at the time of power recovery, regardless of the operation switch ON / OFF state before the power failure stored in the water heater. Also, by setting the invalidity setting means 10 to invalidation, the EEPROM
Alternatively, the operation switch OFF state may be always stored in 9 and the operation switch OFF state data stored in the EEPROM 9 may be read out when the power is restored to start the water heater 1 in the operation switch OFF state.

計れるものである。As described above, according to the first aspect of the present invention, when the water heater before the power failure is in the ON state at the time of power recovery after the power failure, the invalidity setting means causes the water heater to operate with the operation switch ON. It is possible to set whether to start or to start the water heater with the operation switch OFF even if the water heater before the power failure is in the operation switch ON state, and it can respond to differences in customs regarding how to turn on the power locally. In areas where the main power supply is directly turned on and off, when the power is turned on (when the power is restored), the operation switch automatically returns to the previous operation switch ON / OFF state, thereby improving usability. For users who are uncomfortable with starting the water heater when the operation switch is ON, it is possible to start the water heater with the operation switch OFF when power is restored by setting the invalidation setting means to invalid. It is, it is intended that measurably costs can be shared component corresponding to different regions of the specification.

The water heater is started with the operation switch OFF regardless of the N / OFF state data. For example, even in a situation where an earthquake occurs during hot water supply and a power failure occurs immediately after the combustion stop processing is performed. , Operation switch OFF after power recovery
The water heater is started in this state, and even if running water is detected at the time of power recovery, combustion is not started and safety is ensured.
