Abstract

PURPOSE: To prevent secondary dissasters by arranging a temperature sensor in parallel with a heater so as to detect overheating accident or such accidents as breaking of wire in the heater.
CONSTITUTION: A heating medium containing casing 2 fitted on the side face of an engine block 1 is filled with an engine oil 3 as a heating medium. A heater 4 is fitted to the side face of the casing 2 and connected with a power source 7, the heating coil portion being inserted in the oil 3. A temperature sensor 8 is fitted to the side face of the casing 2, in parallel with the heater 4. When the temperature is below a set point, the sensor 8 turns on and is connected with an alarm device 9 such as a lamp and a buzzer. With a current supplied from the power source 7 to the heater 4, the oil 3 is heated to keep the engine block 1 in the warming-up condition. When the heating coil has been broken and the temperature has fallen, the sensor 8 turns on to make an alarm.
