Abstract
An electric device having a casing with an air-outlet, and a main unit disposed inside the casing, includes a first temperature sensor configured to detect the temperature inside the casing, a second temperature sensor installed in the vicinity of the air-outlet, and an electric fan configured to generate an airflow from the air-outlet toward the inside of the casing at the time of the low-temperature startup such that the temperature detected by the first temperature sensor is lower than a preset first threshold value, and the temperature detected by the second temperature sensor is higher than the temperature detected by the first temperature sensor.
