Abstract

PROBLEM TO BE SOLVED: To provide an air conditioner in which air supply efficiency is prevented from lowering by passing the air sucked from an air inlet through a filter during air cleaning operation and preventing the air filter from generating an air resistance in the suction air flow during cooling operation or heating operation and in which the filter can be inserted and removed easily. SOLUTION: A plurality of suction louvers 7 are arranged vertically while being born by a suction panel 6 to conceal an air inlet 2 under first state, to half open the air inlet 2 under second state, to full open the air inlet 2 under third state, and to turn until the back face is directed obliquely upward on the front side under fourth state. A containing section 11 is formed continuously on the back face of the suction louver and a filter 7d is inserted removably such that the air inlet is closed under second state. The suction louver is brought into the second state at the time of air cleaning operation, brought into the third state at the time of cooling or heating operation and brought into the fourth state at the time of inserting/removing the filter.
