摘要： PURPOSE:To raise the efficiency of a centrifugal fan and reduce noises caused by the turbulence in the air flow by forming as one body in the drain pan a blow-out air guide that extends to the blow-out port of the centrifugal fan from the side of the inner circumference of a drain pan, the drain pan being provided below a heat exchanger provided round the centrifugal fan. CONSTITUTION:An air conditioner has a centrifugal fan 6 at the central section in the main body 2 of the case that is buried in the ceiling and a bell mouth 12 that guides the air to the centrifugal fan 6. Below a heat exchanger 7 that is provided around the centrifugal fan 6 a drain pan 10 is provided. In this constitution, the drain pan 10 has a blowout air guide 20 formed as one body with the drain pan 10 by resin injection forming. The blow-out air guide 20 extends to the vicinity of a blow-out port 6a of the centrifugal fan 6 from the side of the inner circumference of the drain pan 10. And the air flow that is blown out from a blow-out port 6a is guided by the blow-out air guide 20 and made to flow into the heat exchanger 7 smoothly. With this arrangement turbulence in the air flow and pressure loss are reduced, and thereby the efficiency is raised and noises are reduced.
