PURPOSE: An automatic blower for a desk is provided to keep a user in the pleasant environment by inducing the wind of upward air streams discharged from a wide fan toward the knees of the user. CONSTITUTION: A case is formed in the curved shape. A motor support and a bearing support are upright installed on the left and right sides in a lower case(20). The motor support and the bearing support simultaneously supports a wide fan directly connected to a fan motor. A swing blade(15) integrated with a swing grip(16) is fitted to the motor support and the bearing support. Many air intake portions(18) are formed on the rear face of an upper case(17) having an intake/exhaust diaphragm. Many auxiliary supports are installed on the inner face of the upper case. An electronic control unit automatically/semi-automatically senses the existence of a user. The air sucked from the rear portion of the upper case is sucked to the upper end of the wide fan. The air discharged toward the lower end approaches the swing blade. The air forms an upward air stream proportional to a control angle of the swing blade. The upward air stream is blown to the front side of a desk.
