Abstract
PURPOSE:To improve the reliability of the full water detecting device by arranging a heater and the temperature sensor in a protecting pipe so as to face to each other, and detecting the decrease in the temperature by said temperature sensor at the time of full water. CONSTITUTION:The temperature sensor 2 is provided in an expanded part 1a of the tip of the protecting pipe 1. The electric heater 3 is provided around said temperature sensor 2 through an insulating material 4. A sensing part A is formed by the electric heater 3, the temperature sensor 3, and the expanded part 1a of the protecting pipe. The electric heater 3 is preheated. The temperature change in the full water detecting device due to the difference in heat radation between the time of no water and the time of the full water, i.e. the decrease in the temperature at the time of the full water is detected by the temperature sensor 2, and the full water of the full water detecting device is detected.
