DISPLAY DEVICE WITH BOTH FLOWING WATER APPRECIATION EFFECT AND AIR CLEANING OPERATION

摘要

PROBLEM TO BE SOLVED: To obtain a display device which makes air clean while flowing water is appreciated by making the flowing water visible and obtaining both the flowing water appreciation effect and air cleaning operation. SOLUTION: The air cleaning operation and display operation are both obtained. Air is blown to the flowing water 3 from the air blow hole 13 of an air blower 12 with a hood 11 above the upper opening 1 of a water tank. This device makes the visible flowing water 3 flow down in a layer from the upper opening hole 1 of the water tank along the external wall surface of the water tank. A ground electrode 4 is grounded avoiding the inside of the visual field of the flowing water 3. An ionizing electrode 5 is put close to the flowing water 3 and ionizes dust on an atmosphere side. A high-voltage DC power source 6 adds an ionization voltage. A filter 7 is dipped in the water to filterate contaminated air. A circulation pump 10 circulates the flowing water 3 having passed through the filter 7 to the water tank from a surge chamber 8 for water through an air-conditioning device 9.
