ABSTRACT:
A clothes dryer comprises: a cabinet; a drum rotatably installed within the cabinet; and an exhaust port for discharging air having passed through the drum, wherein the exhaust port includes first and second exhaust pipes respectively diverged to both sides of the cabinet, and exits of the first and second exhaust pipes are arranged at positions rotationally symmetric to each other by 180° with respect to a vertical axis passing through the center of the cabinet. Since panels constituting right and left walls of the cabinet are fabricated by one process thus to be commonly applied to the right and left sides of the cabinet, the number of fabrication processes is reduced thus to enhance a productivity.
