PROBLEM TO BE SOLVED: To reduce noises of a blower without increasing the number of component parts by forming a cold air distribution guide plate projecting to the side of the blower and leading cold air in all directions at a portion of a cold air guide plate, which is positioned in front of the blower. SOLUTION: Cold air sucked through a cold air suction port 13 provided in a cold air guide plate 20 passes through a cooler 6 positioned between a bell-mouth 21 and an inner case 5 and is blown to a cold air distribution guide plate 14 formed integrally with the cold air guide plate 20 and conically projected to the side of a fan 11 for a blower, by the fan 11 for the blower, which is rotated by a motor 10 for the blower. With such an arrangement that the cold air distribution guide plate 14 is formed conically and integrally with the cold air guide plate 20 in front of the blower, the turbulent flow of the cold air does not occur. Further, the strength of the cold air guide plate 20 is increased to reduce the vibration thereof, and, furthermore, the number of component parts required becomes smaller. |
