<p>PROBLEM TO BE SOLVED: To provide an oxygen enricher of which the noise caused by cooling air for a motor and the like and adsorbed nitrogen exhaust is decreased effectively. SOLUTION: The guide 61 is installed in the exhaust silencing chamber 51 to rotate the exhaust gas introduced from the exhaust inlet 20 and to exhaust the gas from the exhaust outlet 55 to the outside. As the exhaust gas rotates in the exhaust gas chamber 51 to keep a flow distance and not to flow zigzag and to be smooth flow, the silencing effect is increased.</p> |
