PURPOSE:To provide a motor fan for cold air which has a high cooling capacity, by a method wherein a radiator, having a number of radiating fins formed in a protruding manner, is brought into surface contact with a heat transfer plat located to at least one side of an ice box containing ice therein, and this cools the air through the cooled radiating fins to exhaust it. CONSTITUTION:In operation, a door 4 is first opened to remove an ice box 14, and the box is fully filled with water through a draining port being capable of being closed with a drain plug, not shown. The ice box 14 is placed in a refrigerator with the heat transfer plate 15 down and in a condition that a float 16 rises to the surface to ice water at the inside. After icing, the ice box 14 is placed back in an outer case 1 and on a rib 1c, and the door 4 is closed. When a blast vane 8 is driven by a motor 7 to feed blast in a direction A, the blast makes contact with the heat transfer plate 15, and the indoor air is cooled through the working of radiating fins 23 of a radiator 21 cooled by the ice in the ice box 14 to exhaust it to the interior of a room through an air feed port 9. In which case, the float 16 is floated by water 18 produced as a result of melting to push up an ice 17. |
