PROBLEM TO BE SOLVED: To use a cold air fan having a duct for guiding cold air, diffused from a cold air outlet of a front surface of a frame to an arbitrary place, even in a business establishment. SOLUTION: Cold air is generated by a refrigerating circuit having a compressor, a condenser and an evaporator, and the air diffused from a cold air outlet 6 of a front surface plate 1a of a frame 1 is altered upward by a cold air duct 8. Furthermore, a diffusing side of the duct 8 is formed of a flexible material to guide the air in an arbitrary direction. A metal net-like guard 13 is mounted at a fan scroll 5a of a cold air fan continued to the outlet 6 through a connecting cylinder 7. A flat surface plate 9 for constituting a mount in the frame 1 is provided in the duct 8 of the frame 1 side. The plate 9 is made detachable by a fixing member 10 and a set screw 12. When the duct 8 is removed, the front surface of the guard 13 is opened so that an article attempting to infiltrate into the frame 1 from the duct 8 is made removable. |
