A dryer includes a dryer body, a driving device, a groove, and an upper cover. The groove is located around the opening of the dryer body. The upper cover has a cone shape and is located at the opening of the dryer body. The edge of the bottom of the upper cover is located at the groove. The angle of the cone end of the upper cover makes the water drops condensed on the inner wall of the upper cover slide downward along the inner wall of the upper cover so that they are collected in the groove.
