PROBLEM TO BE SOLVED: To prevent the generation of condensation on the air direction plate at an air outlet port by a method wherein an air shielding body is provided at the lower part of a heat insulating member opposed to the discharging port of a fan casing to disperse outlet air near the discharging port high in air volume, by the air shielding body. SOLUTION: An outer cylinder 11 is provided therein with a heat insulating member 11a, opposed to a discharging port 7a, while an air shielding body 13 is provided below the heat insulating member 11a. The lower part of the air shielding body 13 is provided with tapered part (e) to throttle air toward an air outlet port 12c whereby discharging air, from the discharging port 7a toward the air outlet port 12c through a discharging passage, can be effectively. According to this method, sucking of indoor air through the discharging port 12c is eliminated and the generation of condensation on the air direction plate 12d can be prevented. |
