BLOWER UNIT OF AIR CONDITIONER

摘要

A blower unit for an air conditioner is provided to maintain an inner air inlet port open while softly opening and shutting an outer air inlet port without a noise, thereby improving the performance of controlling the temperature of an air conditioner in case of an outer air mode. An opening and shutting door(3) opens and shuts an inner air inlet port(1a) or an outer air inlet port(1b) by a plurality of door plates(3a) arranged in a row and interworking to rotate. A pinion gear(4) is combined with a rotary shaft of one door plate of the opening and shutting door. A rack gear(5) is engaged with the pinion gear and is connected with an inner air/outer air mode conversion switch by a cable(6) so that the rack gear rotates the pinion gear while interworking with the inner air/outer air mode conversion switch for reciprocation.
