In a laundry treatment apparatus including a cabinet having an opening formed in one side thereof, a door rotatably coupled to the cabinet to open and close the opening, a drum rotatably provided inside the cabinet and configured to accommodate laundry introduced through the opening, a door lock unit provided inside the cabinet and configured to lock the door when the door closes the opening or release a locked state of the door in order to open the opening closed by the door, a communication unit configured to receive remote inputs of a user for communication with an external device, and a switch unit configured to connect or disconnect an external power, a locked state of the door and connection to the external power are maintained while a user maintains remote control after a preset cycle including rotation of the drum is performed.

A dryer includes a rotating drum; a lifter positionable on an inner surface of the rotating drum; an energy harvester positionable inside the lifter so that while the energy harvester is positioned inside the lifter, the energy harvester generates electric power as the rotating drum rotates while the lifter is positioned on the inner surface of the rotating drum; a humidity sensor positionable inside the lifter so that while the humidity sensor is positioned inside the lifter, the humidity sensor receives the electric power generated by the energy harvester and senses humidity; a circuit board positionable inside the lifter and on which the humidity sensor is disposed; and an air passage formed through the lifter so as to allow air inside the rotating drum to pass through the lifter. The humidity sensor senses the humidity according to air passing through the air passage of the lifter.

A dryer including a drum; a heat pump including a compressor, evaporator, condenser, and electronic expansion valve; a user interface; a power module to control power supply to the compressor motor and the drum motor; a duct to receive air from the drum so that the received air flows in the duct to be heated by operation of an evaporator and condenser, and to discharge the heated air to the drum; a plurality of temperature sensors to detect temperature of the heat pump, the power module, and the duct; and a controller configured to identify a factor to be controlled from among a plurality of factors that may cause incomplete drying, based on at least one of output data from the plurality of temperature sensors and opening degree data of the electronic expansion valve, and control the user interface to output a notification of the identified factor to be controlled.

The present invention relates to a combination washing and drying appliance for laundry. The appliance is configured to automatically transfer wet clothes from the washing unit to the dryer unit for automatically drying the clothes. The appliance has either vertical or horizontal stacked washing and dryer units. The washing and dryer units have a common conduit for automatically transferring the wet laundry from the washing unit to the dryer unit after a wash cycle is completed. The dryer unit is automatically activated for drying wet clothes when the wet clothes are deposed in the dryer drum of the dryer unit. The common conduit is accessible only after completion of the wash cycle using sliding doors positioned on the washing tub of the washing unit and the dryer drum of the dryer unit.
