A dryer or combination washer/dryer machine has a drum (12) and a clothes drying circuit (16) recirculates a drying airflow. An inlet (20, 104) and outlet (22, 106) are connected by a conduit (24). A water vapor path (18) includes a sieve (30) and a compressor (32). The sieve (30) is positioned in the conduit (24). The sieve (30) removes water molecules from the drying airflow to reduce relative humidity in the drying airflow. The compressor (32) is coupled with the sieve to draw the water molecules through the sieve into the compressor (32). The compressor (32) heats the water in the water vapor path (18) and passes it to the drum (12). The water condenses in the drum (12) to heat the drum (12) and air within the drum (12) to dry clothes in the drum (12).

A drain system for a laundry appliance is provided. The laundry appliance may be configured as a clothes dryer having a heat exchanger to cool and condense moisture-laden air received from the laundry drum. The drain system utilizes a drain structure to catch condensate from the heat exchanger and evacuate the condensate to a sump area. A blower and blower channel moves the dry air from the heat exchanger back to the drum. To prevent negative pressure in the blower channel from moving the condensate to the sump area, an air channel between the blower channel and sump area provides air flow communication.

The present disclosure relates to an integrated washing-drying machine and a method of controlling the same, the integrated washing-drying machine including a housing, a drying drum disposed at an upper side in the housing and configured to accommodate and dry laundry, a washing drum disposed at a lower side in the housing and configured to accommodate and wash laundry, a heat pump having an evaporator, a compressor, and a condenser and produce hot air for drying laundry and supply the hot air to the drying drum, and a cleaning means configured to clean the condenser by spraying cleaning water to the condenser. In this case, the cleaning means uses, as the cleaning water, at least any one of condensate water produced in the evaporator and washing water to be supplied to the washing drum. With this configuration, when the amount of condensate water is insufficient, the washing water is additionally supplied to clean the condenser cleanly.

A laundry treating apparatus includes a cabinet with an insertion opening defined in a front face, a laundry receiving space in the cabinet, a support assembly in the laundry receiving space for supporting laundry, and a first chamber including an air supply part for supplying dehumidified and heated air into the laundry receiving space. A communication opening in the front face of the cabinet opens to the first chamber. A chamber door is configured to open and close the communication opening. A water discharge tank is detachably connected to the chamber door and stores condensate water discharged from the air supply part. A chamber door conveying part reciprocates the chamber door, and moves the support assembly toward the insertion opening when the door opens the insertion opening.
