Claim:
1. A sterilizable drying machine using ultraviolet radiation, comprising: a casing including a front frame at a front surface and having a door frame at an inlet so that washed laundry can be put into the drying machine through the inlet; a drum rotatably installed inside the casing, to perform drying; a front supporter installed between the front frame and the drum for supporting a front portion of the drum; an ultraviolet light source installed at the front supporter, for sterilizing the inside of the drum by radiating ultraviolet rays; and a control means connected to the ultraviolet light source, for controlling the ultraviolet light source to generate the ultraviolet rays, wherein a diameter of the drum is larger than a diameter of the inlet of the front frame so that the front supporter is formed in a ring shape inclined inwardly to the inlet, and the ultraviolet light source is mounted in a settling groove at an upper portion of the front supporter, and wherein the control means is configured to control the ultraviolet light source to perform a sterilization step and to control a rotation speed of the drum so that air flow velocity inside the drum is below 2 m/s during the sterilization step and the laundry is evenly shaken.
