To prevent an influence of adhesive matters by separating air sucked and introduced in an air-conditioning case from liquid, along with components of detergent and softener which are often mixed with moisture accompanied therewith, passing them through a heat exchange section and discharging the separated water by diluting the high-viscosity detergent and softener components mixed therein.

A suction-inlet-side heat exchange area in a heat exchange area 393a is provided with: a vapor-liquid separation section 24 for separating moisture, which is accompanied with air sucked in from a suction inlet port 391 to a heat exchanger 31 for dehumidification, and components of detergent and softener, which sometimes enter into an air-cleaning and -sending pathway, for dying laundry by sucking and passing air in a water tub 3 to an air-conditioning unit 38, making it dry and high-temperature air and returning it to the interior of the water tub 3; and a separated water drainage passage 23 for collecting the separated water and the components of the detergent and softener which are often contained in the separated water and discharging the collected separated water to the outside by diluting the components of the detergent and the softener.
