<p>PROBLEM TO BE SOLVED: To promote reduction of a cost and to improve assembly workability by reduce the number of part items in such a way that an air filter frame forms a multifunctional structure. SOLUTION: A heat-exchanger 4 and a fan 2 are contained in a casing 1 and an air filter 11 is arranged in a position above a suction port 5, situated at the central part of the under surface of the casing 1, in such a state that the peripheral edge of the suction port is held at an air filter frame 9 fixed at the lower end part of the casing 1 and a drain pan 7 is arranged on the upper surface side of the air filter frame 9. In this case, a09 positioning part horizontally engaged with the drain pan 7 and regulating horizontal movement of the drain pan 7 is arranged at the air filter frame 9 and the drain pan 7 is held in such a state to be vertically nipped between the air filter 9 and the heat-exchanger 4. By providing the air filter frame 9 with a function to position the drain pan 7 and a function to hold it, a need to arrange a positioning member and holding member for a drain pan 7 use only is eliminated.</p> |
