OXYGEN ENRICHMENT MACHINE

摘要

PROBLEM TO BE SOLVED: To provide an oxygen enrichment machine which can be used even at a place with no commercial alternating current available. SOLUTION: The oxygen enrichment machine provides an oxygen enrichment means 2 to generate oxygen enriched air, a conveying means 4 to convey the enriched air and a commercial power converting means 13 to convert commercial alternating current to direct current. The conveying means 4 is constructed so as to be driven by both commercial alternating power supplying means and direct power supplying means, allowing the oxygen enrichment machine to be used even at a place with no commercial alternating current available, to be installed in home and to be carried away easily.
