A washing and drying machine includes a water tank, a rotary drum, an irradiating light source and control means. The rotary drum is rotatably supported in the water tank. The irradiating light source is for emitting a light beam including ultra-violet ray to the inside of the rotary drum. The control means controls the irradiating light source such that the light beam including the ultra-violet ray is emitted to the inside of the rotary drum after the end of the drying process.

1. A drying method for a washing and drying machine that includes a water tank and a rotary drum rotatably supported in said water tank, the method comprising: drying an article in said rotary drum by providing heated air from an outside of said rotary drum into said rotary drum;cooling down, after said drying step, a temperature inside said rotary drum to at least 30° C. and at most 60° C.; andirradiating, under said temperature and after the drying step, a light beam including ultra-violet ray into said rotary drum to provide sun-dried fragrance to the article. 2. The drying method according to claim 1, further comprising: controlling said irradiating step such that only an irradiating step of emitting the light beam including ultra-violet ray into said rotary drum can be performed. 3. The drying method according to claim 1, wherein said irradiating step includes, controlling a door provided to open/close an opening of said rotary drum such that the door is locked while the light beam including ultra-violet ray into said rotary drum is irradiated. 4. The drying method according to claim 1, further comprising: shutting off said ultra-violet ray by a component containing an ultra-violet ray absorber. 5. The drying method according to claim 1, wherein said irradiating step is performed by an irradiating component that is provided on a door provided to open/close an opening of said rotary drum. 6. The washing and drying machine according to claim 1, further comprising: emitting, by an irradiating component provided on said water tank, the light beam including ultra-violet ray to an outer circumferential surface of said surface of said rotary drum, said light beam being emitted through a plurality of through holes penetrating to the inside of said rotary drum in said outer circumferential surface of said rotary drum.
