Claims

[Scope of utility model registration request]

Detects the water temperature in the power supply and the heat insulating heater with a small heat generating capacity connected to this power supply, and when the water temperature is low, turns the first contact ON and turns the second contact OFF. A thermoswitch that turns off the first contact and turns on the second contact when the temperature reaches A1 or higher, which is slightly lower than the boiling temperature of hot water; the first, second, and third timer contacts; and the power supply. a water heater with a large heat generating capacity, which is connected through a first contact of the T-MOS switch and connected in series to a second contact of the T-MOS switch and a third timer contact; a relay connected in parallel to the third timer contact via an automatic reset pushbutton switch; a first normally open contact of the relay connected in parallel to the pushbutton switch; A parallel circuit of a series circuit of the first contact of the switch and the first timer contact, a series circuit of the second contact of the thermoswitch and the second timer contact, and a normally closed contact of the relay in series. and a timer motor connected via a second normally open contact of the relay, the timer motor turning on the first timer contact for a short time by energization, and then turning on the second timer contact. The operation of turning on for a relatively long time is 1.
Repeatedly as a cycle, the O of the second timer contact
An electric kettle characterized in that a third timer contact is turned ON for a sufficient period of time for the water temperature to reach boiling temperature from A□ during the N period.゛
