PROBLEM TO BE SOLVED: To provide a highly useful oxygen enriching machine which can prevent a user from inhaling, together with oxygen enriched air, water drops formed as dew in a path of the oxygen enriched air to the user. SOLUTION: This oxygen enriching machine is equipped with: an oxygen enriching means 15 to generate the oxygen enriched air; a blowing port 7 to blow the oxygen enriched air obtained by the oxygen enriching means 15; an air path 24 to connect the oxygen enriching means 15 and the blowing port 7; and a control means 8 to control the operation of equipment. After start, the control means 8 performs an oxygen enriched air generation operation to blow the oxygen enriched air from the blow port 7 for a prescribed period of time, and then performs an air blow operation to blow air except for the oxygen enriched air from the blowing port 7. Thereby, dewed water generated in a supply path during supply of highly humid oxygen enriched air is dried/discharged by supplying the air except for the oxygen enriched air to prevent the user from sucking water drops together with the oxygen enriched air.
