Abstract

PURPOSE:To avoid the non-available condition of a predetermined hot-water temperature due to the shortage of conduction time period by a method wherein the heater is constituted so as to conduct an exothermal body simultaneously with the restoration of daytime electric power in case the service interruption of the daytime electric power is caused during conduction of the exothermal body. CONSTITUTION:When the conduction of midnight electric power is started, count of night timer HN is started in a timer unit 8a, water temperature Tw and hot-water set temperature Th are taken into a micro-computer 8 and necessary conduction time Hs and conduction starting shift time HP are operated. The obtained HP is compared with the night timer HN and conduction of a heater is started when the condition of HN>=HP is established. On the other hand, when daytime electric power is restored from the service interruption thereof, the micro-computer 8 detects the restoration from service interruption by a daytime electric power detecting circuit 10 and the conduction of the heater is started immediately, therefore, a condition that the conduction time becomes short and the predetermined hot-water temperature becomes not available may be avoided even when the service interruption of daytime electric power is caused during the conduction of the heater.

As shown in the figure. In the figure, first, when the late-night power supply starts, it is detected, the water temperature (Ts'c) is set by the hot water temperature setting means, and the water temperature (Ts'c) is detected by the hot water sensor at the bottom of the tank. 'C) respectively, and using the following formula, the required energization time (H8) of the heating element and
The energization start shift time (HP) is calculated by the calculator.

However, the controller operates on daytime power that is continuously energized day and night, and if there is a daytime power outage while power is being applied in the middle of the night, the power will be restored. Since the configuration is such that the night timer (HN) starts counting from that point on, if a daytime power outage occurs while the heating element is being energized, the energization time will be changed because the midnight power supply time period is determined. This causes a situation where the specified hot water temperature cannot be obtained.

Due to lack of time, one embodiment of the present invention will be described below with reference to the drawings.
