Claims19
A laundry apparatus comprising:
- a tub, the tub including a tub body and a tub opening formed at a front of the tub body;
- a drum rotatable on a shaft and provided in the tub, the drum having at least a predetermined region of a circumferential surface made of metal, the drum having a plurality of penetrating holes provided in the circumferential surface of the drum;
- an inductor provided on the tub body and configured to heat the predetermined region of the circumferential surface of the drum by generating an electromagnetic field;
- an air passage duct including a first duct and a second duct;
- and
- a fan configured to generate air flow through the air passage duct, the first duct being in communication with the tub opening or a front portion of the tub body and the second duct being in communication with a rear portion of the tub body,
- wherein air provided into the tub via the second duct is supplied to an internal space of the drum via the plurality of penetrating holes provided in the circumferential surface of the drum by the fan after exchanging heat with the circumferential surface of the drum and then exhausted to the first duct after passing through a drum opening provided at a front portion of the drum.
