PROBLEM TO BE SOLVED: To provide an oxygen enriching device capable of restraining a load of a compressor at the time when the device stops, capable of restraining a noise and vibration from being generated, capable of restraining therein an adsorbent from being deteriorated with moisture adsorption after the device stops, and provided thereby with a function for discharging surely, to an outside, adsorbed water staying in a piping system and dew-condensed water in a pipe. SOLUTION: This oxygen enriching device carries out sequentially controls of (1) executing an operation at a regular sequence until finishing a purge generation process or until finishing a purge exhaustion process, when recognizing an operation stop signal of the device, (2) operating the compressor 102 under the condition where closing an equalizer valve 107, where opening supply valves 104a, 104b and exhaust valves 104c, 104d of purge generation process side adsorption cylinders 105a, 105b, and where closing supply valves 104a, 104b of purge exhaustion process side adsorption cylinders 105a, 105b and opening exhaust valves 104c, 104d thereof, and (3) stopping the compressor 102 under the condition where opening all of the supply valves 104a, 104b and the exhaust valves 104c, 104d.
