DEVICE FOR VISUALIZING OXYGEN-ENRICHED AIR OF AIR CONDITIONER SUPPLYING OXYGEN-ENRICHED AIR

摘要

PURPOSE: A device for visualizing oxygen-enriched air of air conditioner supplying oxygen-enriched air is provided to make a user believe reliability of the air conditioner. CONSTITUTION: A device includes a water tank(1) supplied with high-pressure oxygen-enriched air through an oxygen supply pipe(7) from an oxygen-enriched air separator(25); an anti-backflow device(2) preventing water in the water tank from flowing back through the oxygen supply pipe to the oxygen-enriched air separator; a bubble generating port(3) installed on an inlet part of the oxygen supply pipe of the water tank and having a plurality of holes formed thereon to make easy to generate bubble of oxygen-enriched air; and a water level controlling device(4) attached on one side of the water tank to control water level in the water tank.
