AIR CURTAIN APPARATUS FOR INSECT PROOFING

摘要

PROBLEM TO BE SOLVED: To provide a one-side blowout type insect proofing air curtain in which an air curtain airflow flowing to an opening flows only in one direction for reducing the number of the facilities of an air suction/blowout device for blowing out the air curtain airflow, and for preventing the deterioration of insect proofing effects around the outlet of the air curtain airflow of the air suction/blowout device which blows out the air curtain airflow.;SOLUTION: The air suction/blowout device having an outside air suction port for sucking outside air and an air curtain airflow blowout nozzle laterally crossing a passage space configuring the entrance/exist of an indoor space is arranged at the side of the passage space where the blowout nozzle is arranged while a blowout angle is maintained so that the blown-out airflow flows toward an exterior space side at an appropriate blowout angle, and a baffle board formed so as to abut against the air curtain airflow at an acute angle for making the air curtain airflow escape to the exterior space side of the passage space is formed at the other side of the passage space. Thus, it is possible to satisfactorily achieve the capturing of an insect by increasing the suction speed of the outside air of the outside air suction port of the air suction/blowout device.;COPYRIGHT: (C)2012,JPO&INPIT
