PURPOSE:To prevent the curvature of an air filter and to smoothly handle the insertion and removal thereof, by a method wherein projections are formed on both sides of the air filter and recesses are formed on the filter insertion part of a decorated cover. CONSTITUTION:A cabinet 1 has a heat-exchanger 2 and an air-sending device 3, and a decorated cover 4 has suction grilles 5 and an outlet 6. Projections 7a, 7b are formed on both sides of an air filter 7 which is formed so as to be inserted into the space between the cabinet 1 and the decorated cover 4 and be removed out of the space, from outside. While these projection and recess parts are acting as guides, the filter 7 is inserted and removed. In this case, the filter 7 is not caught by anything, and has no curvature because the projections 7a, 7b are formed on the filter 7 itself, and thus the filter 7 can be smoothly inserted and removed. |
