The present invention relates to a low noise and low power hair dryer. The hair dryer comprises: a Coanda nozzle having an air inflow portion formed on the external circumferential surface and in which pressed air ventilated in a ventilation fan is entered, an air suction portion formed in one end of a longitudinal direction, and a curve portion which protrudes from the internal circumferential surface to form a gap between the air inflow portion and the air suction portion, guides the air transferred from the air inflow portion to the internal circumferential surface, produces a suction force in the air suction portion, and makes external air sucked; a discharge nozzle coupled with the other end of a longitudinal direction of the Coanda nozzle, and from which the pressed air and the external air transferred from the Coanda nozzle are discharged; and a heater installed inside the discharge nozzle, and heating the pressed air and the external air. |
