BY-PASS TYPE AIR FILTER IN AIR CONDITIONER

摘要

PURPOSE:To directly suck outside air into an air conditioner at the air cleaning period like midnight by forming a by-pass passage wherein outside air does not pass air filters to a passage from an outside air intake to an air conditioner when the air filters are folded. CONSTITUTION:A screw shaft 4 for operating air filters 1...1 is attached to the end of a topmost air filter 2 with a fitting metal by rotating a handle 41 provided on the upper end to move up and down a nut 5 screwed with the screw shaft 4 and to move up and down the air filter 2 integrated with the nut 5. Accordingly, the air filters 2...2 can be spread and folded by the operation of the handle, and thereby, a by-pass passage which is independent of the air filters is formed.
