PURPOSE:To maintain the temperature of the heated liquid at a preset value by a method wherein the temperature of a heater adhered closely to the outer surface of a heating vessel is controlled by the temperature of the outer wall surface of the heating vessel. CONSTITUTION:A rubber heater 2 is adhered to one side surface 1a of the heating vessel 1 and is fixed with an adapter plate 4 having an opening 4a at the center thereof and a spring panel 5. A plate spring 3 is attached to a supporting plate 7 so as to make it easy to release the vessel 1 from the heater 2. A temperature detecting element 8 is attached to a position which is not affected by the heater 2 at the outer surface of the vessel 1 while the temperature detecting elements 10, 11 are adhered and fixed to the spring panel 5. The temperature of the heater 2 is controlled in accordance with the temperature of the outer surface of the vessel 1 which is the output of the temperature detecting element 8. For the further reference, the temperature detecting element 11 is for preventing the over heating of the heater 2. |
