MOTOR DRIVING DEVICE OF WASHING/DRYING MACHINE

摘要

PROBLEM TO BE SOLVED: To miniaturize a motor driving device of a washing/drying machine with a plurality of motors to be simultaneously driven.

SOLUTION: The driving device for simultaneously driving a plurality of motors by at least one processor can be miniaturized by feeding the dc power from a dc power supply bus line to be converted to the ac power by a plurality of inverter circuits consisting of a first inverter circuit 3A and a second inverter circuit 3B; driving a heat-pump compressor motor 4A by the first inverter circuit 3A; driving a rotary drum driving motor 4B by the second inverter circuit 3B; driving a blower fan motor 4C by a third inverter circuit 3C; disposing the plurality of inverter circuits parallel between positive and negative dc power bus lines; and disposing a control means near the inverter circuits.
