Blowing device and air conditioning apparatus having the same |
摘要 |
A blowing device having an air suction guide with an improved structure to reduce blowing operational noise, and an air conditioning apparatus having the blowing device. The blowing device includes a blowing fan, a fan casing placed to cover the blowing fan and having a suction port, and a suction guide provided in the suction port of the fan casing to guide inlet air to the blowing fan. The suction guide includes a flow guide part extending forward from an edge of the suction port of the fan casing by a predetermined length. Due to the flow guide part of the blowing device, the inlet air flows through the suction port at a constant flowing speed and in a state of laminar flow. Therefore, the blowing device reduces a variation in a pressure applied onto blades of the blowing fan by the inlet air, and reduces operational noise thereof.
