PURPOSE:To prevent the sound of blowing the air by forming a guard to guide the flowing air and to protect a blower to a unit case integrally, arranging numerous guard elements almost concentrically to the center of the blower, and forming roundnesses at the edges on the leeward of the elements. CONSTITUTION:An air conditioner unit is composed by installing a heat exchanger 1 and a blower 2 with a motor 2a in an outer box 3 which composes a unit case, and a guard 4 to guide the flowing air from a blower 2 and to protect the blower 2 is furnished to the other box 3. In this case, the guard 4 is formed of the material plate same as the outer box 3, and formed unitary with the outer box 3. Moreover, the guard 4 is formed by furnishing numerous guard elements 4a to 4d concentrically to the center of the blower, and the elements 4a to 4d are formed to have a roundness in a U-shape, for example, at the leeward side of the air flowing direction. Consequently, the resistance of the flowing air is reduced, a separation of the flowing is prevented, and the noise is reduced. |
