Abstract

PURPOSE: To secure a stable drying efficiency and safety for a long time by letting the machine be equipped with a dry air circulating passage through which generated dry air flows, and with a filter removing waste yarn and the like at the suction port side of the dry air circulating passage mutually communicated with a dry air inlet port. CONSTITUTION: After washing has been over, water spinned by the rotation of a spinning basket 5 is drained out of spinning holes 21. Subsequently after spinning has been over, and when drying operations are started, dry air generated by a heater 45 is sent to the spinning basket 5 from a dry air intake port 17, and drying operations thereby take place. Dry air having done drying is returned to a dry air circulating path 7 from a dry air intake port 19. In this case, dry air is dehumidified when it passes through a dehumidifier 43, and sent to the spinning basket 5 again from the dry air intake port 17. While drying operations are carried out, waste yarn and the like produced in the spinning basket 5 are removed by a filter 47. Therefore, the dehumidifier 43, the heater 45 and the like are prevented from being adversely affected.
