<p>PURPOSE:To prevent lowering of dehumidifying capacity and the occurrence of overheat and firing by a method wherein the abnormal increase of an exhaust gas temperature is detected and informed to a user and the maintenance period of a filter is properly indicated to the user. CONSTITUTION:Formation of a dehumidifying device is such that a fan 5, a heater 6, and a ventilating moisture absorbent 7 are disposed, in the order, from a suction port 1 side to the discharge port part 2 side in an internal ventilation passage 4 of a casing 3 having the suction port part 1 and the discharge port part 2, and a filter 8 for removing dust is arranged in the internal ventilation passage 4. A temperature sensor 9 to detect an exhaust temperature is arranged at the discharge port part 2. Further, the dehumidifying device is provided with a control part 10 to decides that an exhaust gas temperature detected by the temperature sensor 9 exceeds a preset decision temperature and changes and corrects the decision temperature according to an ambient temperature and a display part 11 to announce the decision by the control part based on the decision by the control part 10.</p> |
