A laundry treating apparatus comprising: a cabinet having an opening defined in a front face thereof; a drum disposed rotatably in the cabinet and having a laundry inlet defined in a front face thereof through which laundry is input into the drum; a base disposed below the drum and providing a space in which air inside the drum circulates; and a motor configured to provide power to rotate the drum, wherein the base comprises: an air circulating channel communicating with the drum, and intaking air from the drum and re-supply the air to the drum; a heat exchanger comprising a first heat exchanger disposed inside the air circulating channel to cool the air, and a second heat exchanger spaced apart from the first heat exchanger to heat the air cooled by the first heat exchanger; a water collector body disposed out of the air circulating channel and communicating with the air circulating channel and constructed to collect water condensed in the first heat exchanger; a pump for moving the water collected in the water collector body; a cleaning water channel disposed on a top face of the air circulating channel, and receiving water from the pump, and discharging the received water to the first heat exchanger; and characterized by a nozzle cover coupled to the top face of the circulating channel so as to shield the cleaning water channel. a cabinet having an opening defined in a front face thereof; a drum disposed rotatably in the cabinet and having a laundry inlet defined in a front face thereof through which laundry is input into the drum; a base disposed below the drum and providing a space in which air inside the drum circulates; and a motor configured to provide power to rotate the drum, wherein the base comprises: an air circulating channel communicating with the drum, and intaking air from the drum and re-supply the air to the drum; a heat exchanger comprising a first heat exchanger disposed inside the air circulating channel to cool the air, and a second heat exchanger spaced apart from the first heat exchanger to heat the air cooled by the first heat exchanger; a water collector body disposed out of the air circulating channel and communicating with the air circulating channel and constructed to collect water condensed in the first heat exchanger; a pump for moving the water collected in the water collector body; a cleaning water channel disposed on a top face of the air circulating channel, and receiving water from the pump, and discharging the received water to the first heat exchanger; and characterized by a nozzle cover coupled to the top face of the circulating channel so as to shield the cleaning water channel. an air circulating channel communicating with the drum, and intaking air from the drum and re-supply the air to the drum; a heat exchanger comprising a first heat exchanger disposed inside the air circulating channel to cool the air, and a second heat exchanger spaced apart from the first heat exchanger to heat the air cooled by the first heat exchanger; a water collector body disposed out of the air circulating channel and communicating with the air circulating channel and constructed to collect water condensed in the first heat exchanger; a pump for moving the water collected in the water collector body; a cleaning water channel disposed on a top face of the air circulating channel, and receiving water from the pump, and discharging the received water to the first heat exchanger; and characterized by a nozzle cover coupled to the top face of the circulating channel so as to shield the cleaning water channel.
