洗濯乾燥機
Document Type and Number:
Japanese Patent JP4517501
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To drive a plurality of motors by controlling a plurality of inverter circuits by a control means, to freely control the number of rotation regardless of the frequency of an electric power source and to realize downsizing and low price in a washing and drying machine in which each process of washing, rinsing, dehydrating and drying is controlled. SOLUTION: An inner tank is freely rotatably supported in the outer tank being hung in a casing and the inner tank or a rotor blade is driven by means of the first motor 37 and a self-water suction pump for suction of water such as water in a bathtub is driven by the second motor 40 and a blower for drying for blowing hot air heated by means of a heater 15 is driven by means of the third motor 43. A DC electric power in rectifier circuits 31, 32 and 33 connected with an AC electric source 29 is converted to an AC electric power by means of a plurality of inverter circuits 34, 35 and 36 to drive the first motor 37, the second motor 40 and the third motor 43. The control means 46 is constituted in such a way that it simultaneously controls a plurality of the inverter circuits 34, 35 and 36 and simultaneously drives a plurality of the motors.
