PURPOSE:To make it possible to grossly change the direction of wind and contrive to improve easiness of operation by constituting so as to change the direction of a discharge grille itself and at the same time inserting a projection provided on the grille into a cut-out portion of a box body to fix the grille. CONSTITUTION:A discharge grille 2a made of resin and metallic reinforcing plate 5 are mutually fastened by a screw 6, and projections 2b and 5a are provided symmetrically with respect to the center line AB of a discharge grille constituting member 2. The projections 2b and 5a of the discharge grille constituting member 2 are inserted into a cut-out section 1a provided on a box body 1 and they are fixed. With this arrangement, by blowing air from a blower device 3 the air which exchanges heat in a heat exchanger 4 can be switched in the air blowing by blowing reversing to the right or left the discharge grille constituting member 2. Further, due to the fastening the discharge grille to the metallic reinforcing plate 5 as one body it is possible to secure strength in either of the air blowing directions. |
