  • Patent number: 8511324
    Abstract: A washing/drying machine according to the present invention is capable of efficiently performing a drying operation to reduce a drying period. The washing/drying machine includes a tank (11) for storing used water, and the water is circulated from the tank (11) for dehumidification of air circulated through a drying air duct (20). Since the water is circulated from the tank (11), a great amount of water can be supplied as dehumidification water for higher dehumidification efficiency. The amount of the circulated water (the amount of cooling water (dehumidification water)) is reduced in a first half of a drying process, and increased in a second half of the drying process. As a result, the drying efficiency is improved during the drying operation, thereby reducing the drying period.
