Abstract: A washing machine includes a drum and a condensing duct connected with the drum. The condensing duct includes an air inlet, an air outlet and a condensing unit. A condensation water spray member is disposed in the condensing duct and a condensation water dispersing plate is supported by a lower portion of an inside wall in the condensing unit, and formed with an air-passing hole connected with the air inlet in a center portion thereof.

Abstract: A washing machine, includes a drum; a condensing duct to condense air which flows in from the drum; a cooling water supplying unit to supply cooling water to the inside of the condensing duct so that the air flowing into the condensing duct from the drum is condensed; and a control unit to control the cooling water supplying unit so that the cooling water is supplied intermittently. Thus, a washing machine is provided that is capable of reducing the consumption amount of cooling water, increasing an efficiency of drying laundry and shortening the time for drying the laundry.

Abstract: A washing machine includes a drum and a condensing duct that communicates with the drum. The condensing duct includes an air inlet unit, a condensing unit and an air outlet unit which are connected sequentially. A condensed water jetting member is provided inside the condensing unit and a backward flow blocking guide is provided inside the condensing unit. The condensing unit has a flow width larger than the air inlet unit and the air outlet unit.

Abstract: A drum washing machine includes a drum; a drying duct communicating with the drum; a fan for introducing air into the drying duct; and a heater provided in the drying duct and for heating the air from the fan. The drying duct is insulated so as to prevent heat generated by the heater from being radiated outward. Thus, the drum washing machine prevents heat generated by the heater from being radiated from the drying duct, thereby reducing heat-loss.

Abstract: A washing machine includes a drum; a discharging duct communicating with the drum, and discharging inner air of the drum; a supplying duct communicating with the drum, and supplying external air into the drum to make a flow direction of the external air pass across that of the inner air; and a heat exchanger connected to the discharging and supplying ducts, in which a first air flow path which passes therethrough the inner air discharged outward through the discharging duct and a second air flow path which passes therethrough the external air supplied into the drum through the supplying duct cross each other. The washing machine may also include a humidity regulating part which reduces the humidity of the inner air as it is discharged. Thus, the washing machine improves efficiency of heat exchange between the inner air and the external air through the heat exchanger.

Abstract: A washing machine is provided that includes a drum; and a condensing duct that communicates with the drum and is supplied with air from an inside of the drum. A coolant spray is provided inside the condensing duct, and sprays coolant from a lower portion to an upper portion of the condensing duct. A washing machine is thus provided that enhances condensation efficiency by increasing a contact time between hot moisture-laden air in a condensing duct and the coolant while decreasing time consumed during a drying phase. In addition, the washing machine can enhance the condensation efficiency by changing a spray direction of a coolant spray device.
