The present invention relates to an air circulator which circulates air inside or outside a fabric drying machine (1). The air circulator comprises an air suction part (10), an air exhaust part (20), a control part (30), and an air ventilation part (40). The air suction part has an air suction duct (11) communicating with an upper portion of the drying machine and sucking cool air from the outside to the inside. The air exhaust part has an air exhaust duct (21) communicating with the upper portion of the drying machine and exhausting hot air from the inside to the outside. The control part has a control plate (31) and a humidity sensor (35), which are installed at the air suction part and the air exhaust part and control the amounts of suction air and exhaust air. The air ventilation part has air ventilators (45, 46) mounted on the suction duct and the exhaust duct, respectively. The air ventilators suck or exhaust the air inside or outside the drying machine by a motor (41). As described above, the motor is used to operate the air ventilators, thereby simplifying the fabric drying machine, and minimizing noise and breakdown. Further, the control plate and the humidity sensor are used to control the amounts of suction air and exhaust air, thereby precisely balancing the suction air and the exhaust air. Further, the exhaust duct and the suction duct intersect each other, thereby sucking a suction air having increased temperature, and thus preventing dew condensation in the drying machine. Further, the waste heat released to the outside is collected by heat exchange, thereby saving overall energy. |
