<p>PURPOSE:To prevent malfunction, etc., at the time of a low temperature by providing a temperature sensor to detect an outside air temperature, stopping an electric fan when the outside air temperature is <= the operation temperature of a temperature sensor, and operating the electric fan when the outside air temperature is >= the operation temperature of the temperature sensor. CONSTITUTION:When the outside air temperature is <= the operation temperature of a temperature sensor S1 in a condition in which the temperature in the title device is cooled, an electric fan 5 is stopped. For this reason, the cooled air is not taken into the device, and heating in the device warms the inside of the device. When the outside air temperature is >= the operation temperature of the temperature sensor, the electric fan 5 is operated, and when the inside of the device is cooled in winter, the warm outside air is taken into the device, and the inside of the device is warmed. On the other hand, at the time of the normal temperature or more or in summer, the outside air is taken into the device and the inside of the device is cooled. Consequently, when the outside air of the device set in a cold area in winter is at the low temperature, the outside air is not taken in and the heating in the device warms the inside of the device. Thus, grease, oil, etc., in the mechanism part are not solidified, and the mechanism part normally operates.</p> |
