<P>PROBLEM TO BE SOLVED: To provide a washing drying machine by which drying operation time can be shortened and consumed power can be reduced. <P>SOLUTION: The washing drying machine has an inverter circuit 83 controlling a compressor motor 45M driving a compressor in the case a heat pump is constituted within the washing drying machine, and the inside laundry is dried by directing air heated by a condenser into a rotary tank, while the exhaust air from the rotary tank is circulated so as to reheat the same by the condenser dehumidified by an evaporator. Also, a drying step control section 70 operates the compressor motor 45M by a weak field by a voltage-phase control in an initial step of drying operation thereafter operates the compressor motor 45M by a full field shifting the control to a vector control controlling by current. <P>COPYRIGHT: (C)2009,JPO&INPIT |
