<P>PROBLEM TO BE SOLVED: To provide an oxygen concentrator with high safety capable of informing early to a user that the oxygen concentrator is not used under a normal condition, and especially that an intake vent or the like is closed. <P>SOLUTION: The oxygen concentrator includes: an air intake part for introducing a raw material air; an air compressing part for forming an compressed air from the raw material air introduced through the air intake part; a PSA part for forming a high concentration oxygen by separating nitrogen from the compressed air formed at the air compressing part; an oxygen supplying part discharging the high concentration oxygen formed in the PSA part from an oxygen outlet; and a fan part for cooling the air compressing part by introducing an open air from the intake opening and blowing it toward the air vent. In the oxygen concentrator, whether the air intake opening or the air vent is closed or not, is monitored, and when it is determined that the intake opening or the air vent is closed, it is informed from an informing part (a closed condition monitoring part). <P>COPYRIGHT: (C)2012,JPO&INPIT |
