<p>PROBLEM TO BE SOLVED: To provide an oxygen enricher of which the air compressor and its motor are cooled effectively without losing noise prevention effect. SOLUTION: On the oxygen enricher 100 which produces highly enriched oxygen gas from a compressed air, the air compressor 40 and its motor are supported in the sound insulation compartment 41 to keep space around the up and down and horizontal sides in the enricher. The first opening 18 is located on the ceiling of the sound insulation compartment 41. The air compressor 40 and the like are cooled by the downward air flow from the fan 30 through the first opening 18. The second opening 20 is located on the floor of the second insulation compartment 41. The exhaust silencing chamber 51 is located under the floor and has the second opening as the exhaust inlet and has the third opening 55 as the exhaust outlet and is pasted inside with a silencing material. As the air to cool the air compressor flows like top-to-bottom and simple stream and is exhausted outside, the cooling efficiency is much increased.</p> |
