<P>PROBLEM TO BE SOLVED: To provide a simple cold wind device for an electric fan, convenient and economical, by which a comfortable life can be led while conserving electricity with a room air temperature reduced to one several degrees C less than a preset cooling temperature of an air conditioner, by changing an electric fan into a cold wind device (cold wind fan) only by mounting this cold wind device on an existing electric fan to send cold wind. <P>SOLUTION: A simple cold wind device for an electric fan includes a water retaining material 1 arranged on a front side of fan blades 10b of the electric fan 10 and is ventilatable, a water storage container 2 arranged at a position higher than the water retaining material, and a water supplying tube 3 for supplying the water stored in the water storage container to the water retaining material 1. This simple cold wind device is mounted on the electric fan 10 and the water retaining material 1 is arranged directly in front of the fan blades 10b of the electric fan. When rotating the fan blades 10b of the electric fan to send the cold wind while supplying water inside the water storage container 2 to the water retaining material 1 via the water supplying tube 3 to permeate the water into the water retaining material 1, the water permeated into the water retaining material 1 to be retained there is evaporated by wind passing through the water retaining material 1 for the vaporization heat to be drawn by the wind and therefore the electric fan 10 acts as a cold wind device (cold wind fan), permitting ambient temperature to be lowered by several degrees C. <P>COPYRIGHT: (C)2013,JPO&INPIT |
