DEVICE HAVING SUPPLY AND EXHAUST OPENING ABNORMALITY DETECTING FUNCTION AND METHOD FOR DETECTING SUPPLY AND EXHAUST OPENING ABNORMALITY

摘要

PROBLEM TO BE SOLVED: To provide a device capable of detecting closing (clogging of a filter) before the temperature of the internal part of a device reaches an abnormal value by detecting a temperature difference between an internal temperature and an external temperature and simultaneously considering a load amount applied on a device at that point of time, in a device having a supply and exhaust opening (particularly provided with a power source unit). SOLUTION: The device comprises an external temperature detecting means to detect the increase of the temperature of the external part of the device; an internal part temperature detecting means to detect the increase of the temperature of the internal part of the device; and a load amount detecting means to detect a load amount of the device. A temperature difference between an external part temperature detected by the external temperature detecting means an internal part temperature detected by the internal part temperature detecting means is calculated. It is decided whether the temperature difference is in a normal temperature difference range in a load amount detected by a load amount detecting means. When it exceeds the normal temperature difference range, it is decided that there is an abnormality in a fan or a supply and exhaust opening, and abnormality information processing to a specified destination is executed. Further, along with the abbve processing a specified device stop processing is executed.
