A drying machine may include a condensation duct for accommodating a condenser, a first drying duct connected to a rear end of the condensation duct and to a drying fan housing accommodating a drying fan, and a second drying duct connected to the drying fan housing and to a drum. The drying machine may also include a first drying duct drain outlet formed in the lower portion of the first drying duct, and an outer rib, which is provided at the side edge of the first drying duct drain outlet that is close to the drying fan housing and that extends upward, so as to prevent condensed water, introduced through the condensation duct, from flowing over the first drying duct drain outlet.
