Meanwhile, as shown in FIG. 3, a driving method of the electric boiler will be described.

The driving method of the electric boiler 100 is largely divided into 1 to 5 steps. The first step is to check whether the storage battery 40 is discharged (S10).

In the second step, when the battery 40 is discharged in the first step, the photosensitive sensor 22 detects sunlight (S20), while the battery 40 is not discharged (S10). The power of the storage battery 40 is supplied to the controller 45 (S90), and the controller 45 is supplied to the heating plates 62 and 72 to be operated (S100).

In the third step, when solar light is detected by the photosensitive sensor 22 in the second step (S20), the solar heat collecting plate 24 collects solar heat (S30), and the solar heat collected in this manner is converted by the converter 26. If it is converted to electrical energy (S40) and, on the other hand, is not detected (S20), it is determined whether it is a late night power use time (S60), and if it is a late night time, the late night power is supplied from the late night power supply unit 34 (S70).

When the product is used after commercializing only the late night power and the storage battery, the battery is charged and operated at the same time as the battery is charged using the power of the midnight power use time (23:00 ~ 07:00).

The power charged in the battery is used in a time zone other than the night time power use time, and after the power of the battery is used up, general power is used. At this time, the general power is not charged in the battery.

The use of low-cost late night power reduces the operating costs and has an economic effect.

In addition, when the product is used after commercializing only solar energy and storage batteries, the solar sensor senses sunlight and collects solar heat from the solar heat collecting plate, and converts the collected solar energy into electrical energy through a converter to charge the battery. At the same time, the electric boiler is powered and operated.

If the photosensitive sensor fails to detect sunlight, the electric boiler is operated using general power.

As in the case of using the late night power, the general power is not used to charge the battery.

In addition, when the product is used after commercializing only the general power and the storage battery, the battery is charged with power, the power is supplied to the electric boiler, and the battery is used only in the event of a power failure or emergency. The capacity of the electric boiler does not have to be so large that the size of the electric boiler can be made easy.

As described above, it can be mass-produced separately for each electric power, and can be individualized, thereby providing an electric boiler suitable for a situation.

By using the boiler as it has the advantage of reducing the installation cost.

In addition, since the preheating tube is provided inside the water heating supply unit, the cold water supplied to the outside is preheated and moved to the main container, thereby providing hot water and heating water at a constant temperature without changing the temperature.

As described above, the electric boiler driving apparatus and driving method according to the present invention reduce the operating cost by charging electricity to a battery using solar energy and low-cost late-night power for high efficiency heating. It is effective to reduce the installation cost by using existing equipment.

In addition, it is a useful invention having the advantage of supplying hot water and heating water of a constant temperature without changing the temperature by having a preheating tube inside the water heating supply unit is preheated to move the cold water supplied to the outside.
