Abstract: Disclosed is a laundry treatment apparatus equipped with an exhaust type drying system, which is capable of not only enhancing drying efficiency while reducing consumption of energy and cooling water required to dry laundry, but also achieving smooth exhaust of air even when a water trap is formed in a drainage duct. The laundry treatment apparatus includes a casing, an outer tub, an inner tub, a drainage duct for guiding wash water stored in the outer tub to be discharged to the outside of the casing, a first exhaust duct connected, at one end thereof, to the drainage duct, to guide air present in the outer tub into the drainage duct, and a second exhaust duct upwardly branched from the drainage duct, to exhaust air present in the drainage duct to the outside of the outer tub or the outside of the cashing.

Abstract: A dryer having a waste heat recovery device includes a cabinet, a drum rotatably mounted within the cabinet and having a front surface and a rear surface, an intake duct configured to provide an intake flow path through which air flows into the drum, an exhaust duct configured to exhaust air coming from the drum out of the cabinet, a heater configured to heat air flowing into the drum, and an ambient air duct configured to inhale air from outside the cabinet and supply the air from outside the cabinet into the drum. The waste heat recovery device includes an evaporation unit configured to absorb heat from air that is exhausted from the drum, a condenser unit configured to transfer heat absorbed from the evaporation unit to ambient air that flows into the ambient air duct, and a heat transfer medium configured to transfer heat between the evaporation unit and the condenser unit. The ambient air duct is configured to communicate air from the ambient air duct into the intake duct at a point along a flow path between the drum and the heater.

Abstract: The present disclosure relates to a laundry treatment machine. The laundry treatment machine according to an embodiment of the present invention includes a casing; a door attached to the casing; a washing tub disposed inside the casing; a heating unit; a blower for supplying to the washing tub; a temperature detector for detecting a temperature of the washing tub; a motor for rotating the washing tub; a driving unit for driving the motor; and a controller to control the blower to operate in a first drying mode, and to control the heating unit to intermittently output a first power during a first period after the operation of the blower while controlling an operating time of the heating unit to increase during the first period. Accordingly, the power consumption can be reduced while reducing the drying period in the drying mode.

Abstract: A clothes treatment apparatus includes a cooling water pipe that is placed within a condensing duct to condense humidity contained in a circulating air current. The latent heat generated from the condensation of humidity causes the temperature of the cooling water in the cooling water pipe to rise. A thermoelectric pump mechanism collects heat from the higher-temperature cooling water and uses it in heating the circulating air.
