る。DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to a daytime electric heater that heats water in a hot water storage tank using daytime electric power, and a nighttime electric heater that heats water in the hot water storage tank using late night electric power. A control circuit for a two-load, two-power electric water heater equipped with an electric heater. For the purpose of downsizing and energy saving, a two-load, two-power electric water heater is equipped with a daytime electric heater that uses daytime electricity. It is used for replenishment, and the most effective time to apply electricity is from the time the power is cut off in the morning and late at night until the evening.
それ以降の通電は、通電コストの安い深夜電力で通電し

タを通電するメリットがないばかりでなく、通電コスト
の高い昼間電力を快うために、経済性が悪い。After that, it is more economical to turn on electricity using late-night electricity, which is cheaper. For example, if a large amount of hot water in the hot water storage tank is used for taking a bath at 8 p.m., the water is heated by an electric heater during the daytime until water is supplied to the hot water storage tank and the midnight electricity starts. However, after 8 p.m., the water in the hot water storage tank will boil by the time the user goes to bed, making it impossible to use it for the rest of the day, and not only is there no benefit to turning on the electric heater during the day, but it also costs money. It is not economical because it requires high daytime power consumption.
また、昼間電気ヒータで予熱されているため、夜間電気
ヒータによる沸き上げが早くなり放熱ロスが大きく省エ
ネに反するというデメリッ]・がある。In addition, because the water is preheated during the day by an electric heater, it has the disadvantage that the electric heater at night heats up the water quickly, resulting in large heat radiation losses, which goes against energy conservation.
これに対して、昼間電気ヒータをタイマ回路によりある
一定の時間だけ通電可能にして、不要な通電は行わない
という方法が考えられる。しかしそれだけでは、ユーザ
ーの使い方もまちまちであり、上記の問題点を完全に解
消するものではない。On the other hand, a method can be considered in which the electric heater is enabled to be energized during the daytime only for a certain period of time using a timer circuit, and unnecessary energization is not performed. However, this alone does not completely solve the above-mentioned problems since users use the system in different ways.
例えばタイマ回路により、深夜電力の停止する午前7時
から夕方6時までの11時間を昼間電気ヒータの通電時
間としてセットした場合を考える。For example, consider a case in which a timer circuit is used to set the 11 hours from 7 am to 6 pm, when power is cut off in the middle of the night, as the daytime electric heater energization time.
夕方7時に入浴で大量に給湯した場合は通電時間外であ
るから、昼間電気ヒータは通電せず上記問題点の解消に
なっている。しかし夕方4時に入浴で大量に給湯をした
場合は、夕方6時までは昼間電気ヒータが通電するため
、昼間電力の無駄な使用になり経済性がよくないという
問題点を有するものである。If a large amount of hot water is supplied for taking a bath at 7:00 in the evening, it is outside the energization time, so the electric heater is not energized during the day, which solves the above problem. However, if a large amount of hot water is supplied for taking a bath at 4 p.m., the electric heater is turned on during the day until 6 p.m., which results in a waste of daytime power and is not economical.

う問題点を解消するものである。Purpose of the Invention In view of the above-mentioned conventional problems, the present invention has been made to reduce daytime electric power by enabling a timer circuit to energize a daytime electric heater that heats water in a hot water storage tank using daytime electric power. This eliminates wasteful energization and improves economic efficiency, and also solves the problem that the boiling time is too early, which goes against energy conservation.
更に、昼間電気ヒータ通電時間内に大量の給湯があった

層の経済性を高めるものである。Furthermore, if a large amount of hot water is supplied during the daytime electric heater energization time, the power supply to the daytime electric heater is stopped, thereby further increasing economic efficiency.

The electric heater is configured to stop energizing the daytime electric heater when the amount of remaining hot water decreases to less than a predetermined amount within a certain period of time.
