うものである。The diode 11, the resistor 12, the capacitor 13 and the constant voltage diode 14 constitute the power supply circuit 3, rectify an AC voltage to generate a DC voltage and supply the DC voltage to other electric elements. The current detection means 4 rectifies the current transformer 15, the resistor 16 serving as the load, and the voltage generated in the resistor 16 in order to detect the current flowing to the load 7 in the current supply line from the AC power supply 1 to the load 7. It is composed of a diode 17 for converting into a DC voltage signal, a resistor 19, and a capacitor 18. The current drop detection means 5 receives the output of the current detection means 4, detects the output current when it drops, and outputs a signal. In order to detect the current drop, the current drop detection means 5 outputs a signal. Capacitor 23 and diode that store the minimum value corresponding to the maximum value obtained by dividing the maximum output value with resistors 21 and 22.
From the current value voltage dividing storage means constituted by 20 and the comparison detecting means 24 (hereinafter referred to as comparator 24) which inputs the divided voltage and inputs the output of the current detecting means 4 for comparison. Composed. Normally, the output of the current detection means 4 is
Since it is higher than the voltage divided by the resistors 21 and 22 and stored in the capacitor 23, the comparator 24 outputs a low voltage. However, when the output of the current detection means 5 decreases, the decreased voltage remains at the negative input terminal of the comparator 24 and the previously stored voltage remains at the positive input terminal, which is lower than the stored voltage. When the output of the current detecting means 4 decreases, the input state of the comparator 24 is inverted and the comparator 24 outputs a high voltage. As a result, the notification means 6 sends the notification to the outside.
Is Umono.

がったことを知ることができる。Next, when the hot water is boiled, the jar pot of the load 7 is automatically switched to the heat retention state, and the temperature of the hot water is maintained with low power consumption. At this time, the current supplied to the load 7 decreases as shown by T 2 to T 3 in FIG. 2B, and the time constants of the capacitor 18 and the resistor 19 are made short accordingly, so that the current detection The output voltage of the means 4 also decreases.
The time constant of the capacitor 23 and the resistor 22 in the current drop detecting means 5 is configured to be larger than that of the current detecting means 4,
Even if the output of the current detecting means 4 is lowered, the voltage of the capacitor 23 is slowly lowered while remaining (FIG. 2, dT 2- ).
T 3 ). At this time, the input voltage of the comparator 24 is reversed between the negative terminal and the positive terminal, the positive input of the comparator 24 becomes high, and the output outputs a high voltage (eT 2 to T 3 in FIG. 2 ). The notification means 6 receives this signal and performs an external notification operation. This allows the user to know that the hot water in the jar pot of load 7 has boiled.
