<p><P>PROBLEM TO BE SOLVED: To provide an inexpensive detection device of a drain discharge abnormality quickly detecting a discharge abnormality of drain water, and to provide a compressed air dehumidifier. <P>SOLUTION: The detection device of a drain discharge abnormality detects a discharge abnormality of drain water in compressed air equipment. The detection device includes a pressure sensor 26 detecting pressure of a cheese 25 downstream of a solenoid valve 24 discharging the drain water, and a control part 4 controlling open/close of the solenoid valve 24. The control part 4 performs abnormality determination when pressure difference between pressure detected by the pressure sensor 26 before and after the control part 4 controls to open the solenoid valve 24 is smaller than predetermined pressure difference. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
