To reduce the height of a drier, to compact the whole structure and to obtain excellent drying performance by connecting a hot air generator and a hot air feeding port at the lower part of a drier and providing a drying drum provided with a lower feeding port and an upper discharge port inside the drier.

The hot air generator 13 is mounted adjacently to the drier 10 and the hot air feeding port 10b at the lower part of the drier 10 and the hot air generator 13 are connected through a hot air feeding duct 14. A circular drying drum 10c provided with the upper discharge port 10aa and the lower feeding part 10bb is disposed inside the drier 10 and a hot air discharge duct 10a is connected to the upper discharge port 10aa. Thus, at the time of washing and drying, inside the drier 10, since hot air fed from the lower part is made to pass through the circular drying drum 10c provided with the upper discharge port 10aa and the lower feeding port 10bb in the inside and discharged, the drum passing property of the hot air is excellent, the convection balance of heat becomes uniform and drying efficiency is improved.
