ABSTRACT:
Disclosed is a washing machine and dryer having a condensation unit (700). A tub (200) is installed in a cabinet (100), and a drum is rotatably installed within the tub (200). A drying duct (610) has one end connected with an interior of the tub (200), and a condensation duct (710) connects the tub (200) with the drying duct (610). A cooling water supply unit (720) is provided in one side of the condensation duct (710) to supply cooling water supplied from an outside to the interior of the condensation duct (710). A cooling water dropping unit (750) collects the cooling water supplied to an interior of the condensation duct to drop the collected cooling water to the inner space of the condensation duct. A heater (620) heats air circulating the tub (200), the condensation duct (710), and the drying duct (610), and a circulation fan (800) circulates the air. A drain pump (500) discharges washing water in the tub (200) outside the cabinet (100). To dry laundry in the drum (300), the drum (300) rotates, the heater (620) and the circulation fan (800) operate, and cooling water is fed into the condensation duct (710) through the cooling water supply unit (720). Moist absorbing moisture while drying the laundry in the drum (300) exchanges heat with the cooling water dropped by a cooling water dropping unit (750) while being via the condensation duct (710), and is condensed to remove moisture, so that dry performance of the washing machine is enhanced.
