The present invention relates to a wingless fan, and more specifically, to a wingless fan generating an air flow without a wing and comprises a ventilation body with a double structure, thereby achieving uniform distribution of the air flow and increasing the supply range of the air flow. The wingless fan comprises: a main body; a first ventilation body; a second ventilation body; and a control part. The main body has a plurality of air introduction openings formed on one side thereof to allow external air to be introduced and has a fan and a motor mounted on the interior thereof. The first ventilation body is installed on the upper part of the main body, sucks air in from the main body through a first ventilation opening formed inside. The second ventilation body is connected to the upper end of a supply duct installed on one side of the inner circumferential surface of the first ventilation body to be arranged in a concentric circle of the first ventilation body and there is a second ventilation opening formed inside. The control part is installed on the lower part of the interior of the main body to control the operation of the motor. |
