Abstract

PURPOSE: To open a heater circuit securely when the heater is not in use, water has reached boiling point, or the heater works with water emptied in a kettle, by constituting a magnetic circuit with a ferrite having Curie point at temperature of boiling point and a thermal relay.
CONSTITUTION: When a ferrite 5 having Curie point at temperature of boiling point is fixed on the top of a handle 9 outside a vessel 1 and a control unit A provided with a heater 2 is installed on the portion where the ferrite 5 is fixed, ends of wrought iron plates 3-1, 3-2 holding at thermal lead switch 4 connected in series to the heater 2 and a magnet 3 come in contact with the ferrite 5. A line of magnetic force from the magnet 3 works only on the ferrite 5 where the temperature does not reach boiling point, and the thermal lead switch 4 is closed to keep conducting to the heater 2. Where the control unit A is not installed and water has boiled up, the line of magnetic force works on the thermal lead switch 4 to open, thus discontinuing carrying the current to the heater 2.
