ABSTRACT:
A washing and drying machine that is capable of performing heat exchange between outside air introduced into a cabinet and the circumferential surface of a tub so as to condense air used to dry laundry. No cooling water is used to condense air used to dry the laundry. Consumption of water is reduced, and therefore, the maintenance costs of the washing and drying machine are decreased. Furthermore, no condensing duct is necessary. Consequently, flow resistance is decreased, and drying efficiency is improved. In addition, sufficient space is provided between the rear surface of the tub and the cabinet. Consequently, the volume of the drum is increased, and the washing/drying capacity of the washing and drying machine is increased.
