PROBLEM TO BE SOLVED: To provide an oxygen concentrator capable of promptly and smoothly conducting normal operation as the oxygen concentrator or operation of detection or notification of smoking.SOLUTION: When a signal indicating a concentration of CO (and HC), or NOx can be obtained by a smoking detection sensor part 141, the smoking detection sensor part 141 sends the gas detection signal to an electronic controller 143 for smoking (provided separately from an electronic controller 111 for a body), and the electronic controller 143 for smoking determines smoking on the basis of the gas detection signal transmitted from the smoking detection sensor part 141 and received. That is, since the oxygen concentrator includes the electronic controller 143 for smoking determining the smoking separately from the electronic controller 111 for the body performing operation of generation or the like of oxygen concentrated gas, the oxygen concentrator can promptly determine the smoking by the electronic controller 143 for smoking without imposing an excessive load on the electronic controller 111 for the body.COPYRIGHT: (C)2015,JPO&INPIT【課題】酸素濃縮装置の通常の動作や喫検知や報知の動作を、支障なく速やかに行うことができる酸素濃縮装置を提供すること。【解決手段】喫煙検知センサ部141によって、CO(及びHC)、或いはNOxの濃度を示す信号が得られた場合には、喫煙検知センサ部141からそのガス検知信号を、(本体用電子制御装置111とは別体に設けられた)喫煙用電子制御装置143に送り、喫煙用電子制御装置143では、喫煙検知センサ部141から送信されて受信したガス検知信号に基づいて喫煙の判定を行う。つまり、酸素濃縮ガスの生成等の動作を行う本体用電子制御装置111とは別に、喫煙の判定を行う喫煙用電子制御装置143を備えているので、本体用電子制御装置111に過度の負担をかけることなく、喫煙用電子制御装置143によって速やかに喫煙の判定を行うことができる。【選択図】図8
