The present invention relates to a cold fan. More specifically, the present invention relates to a cold air fan that can maximize user convenience and can be used hygienically.

For example, a fan may be used as a home appliance that is used indoors and outdoors in summer. Fans are home appliances that are invented so that the human body can be placed in a more comfortable environment at high humidity and temperature indoors and outdoors during summer by the artificial wind by the rotational movement of the propeller. However, such a fan, as the temperature of the surrounding air rises as the motor for operating the propeller is heated, and the air whose temperature rises becomes an artificial wind according to the rotational movement of the propeller, a hot wind is generated when the fan is used for a long time. It is rather unpleasant.

In order to solve this problem, a cooler has been developed. The cooler is basically similar to that of a fan by a blowing means such as a propeller or an impeller that rotates. Cooling means is further provided to the.

Representative air cooling means have often been provided with a wet cloth.
