LOW-TEMPERATURE DRYING MACHINE CAPABLE OF DRYING LAUNDRY WHILE PREVENTING DAMAGE OR DEFORMATION OF THE LAUNDRY

摘要

PURPOSE: A low-temperature drying machine is provided to prevent damage of the laundry in the process of a drying by effectively eliminating aqueous vapor, which is mixed with the laundry and exists in the air, at low temperature and to shorten the drying time by eliminating the aqueous vapor in the air through by means of saturated vapor pressure. CONSTITUTION: A low-temperature drying machine comprises a drum part(10) where a drum(11) for receiving the laundry is rotatably installed; a circulation duct(20) making one side of the drum part communicate with the other side; a refrigerator; a first heater(40) installed to one side of the inside of the circulation duct to heat the air passing through the circulation duct; a blower fan(50) connected to the circulation duct to make the air exhausted from the drum part pass through a dehumidifying evaporator(31) and the first heater and than to make the air flow into the drum part; a drain valve(60) discharging water obtained through the dehumidifying by the dehumidifying evaporator; an exhaust duct(70) communicating with one side of the drum part and communicating with the outside; a suction duct(80) communicating with the other side of the drum part and communicating with the outside; a suction fan(90) producing suction pressure to make the air flow into the drum part through the suction duct and then to make the air exhausted to the exhaust duct; first and second valves(V1,V2) installed to the exhaust duct and/or the suction duct; and a second heater(75) installed to the suction duct to heat the flowing air. The refrigerator comprises the dehumidifying evaporator installed to the other side of the inside of the circulation duct to dehumidify moisture from air passing through the circulation duct; a compressor pressing a refrigerant passing through the dehumidifying evaporator; and a condenser emitting the heat of the refrigerant passing through the compressor.
