Abstract

The present invention relates to a washing machine driving device capable of minimizing energy consumption when forming a washing water flow in the opposite direction driven by a pulsator and a washing tank in opposite directions in order to form a powerful three-dimensional washing water flow with a high washing degree, and a washing machine having the same and Washing machine driving method. The driving device of the washing machine is characterized in that it comprises: a driving motor with double rotors and double stators, which has an inner rotor and an outer rotor that can be independently controlled by the double stators; an inner shaft that transmits the output of the outer rotor to the pulsator; for transmitting the output of the inner rotor to the washing tank; and a control unit for controlling the inner rotor and the outer rotor, the control unit controls in the following manner: when the washing stroke is performed, the rotation of the pulsator is switched in the clockwise direction and the counterclockwise direction There is a stop time in the direction, and the washing tub is driven in the direction opposite to the rotation direction of the pulsator by starting before the clockwise and counterclockwise driving time of the pulsator ends.

Description

technical field

[0001] The present invention relates to a washing machine, and more particularly, to a washing machine driving device, a washing machine having the same, and a washing machine driving method. When washing the water flow, energy consumption can be minimized. Background technique

[0002] In the washing machine with a spin-drying function proposed in Korean Laid-Open Patent Publication No. 10-1999-0076570 (Patent Document 1), the washing motor has the characteristics of a low-speed, high-torque motor. Compared with the washing motor, the spin-drying motor has the characteristics of a high-speed, low-torque motor. , the above-mentioned washing motor is an outer rotor type with a diameter larger than that of the dehydration motor, the dehydration motor is an inner rotor type, the washing motor is on the outer side, and the dehydration motor is on the inner side.

[0003] In the washing machine of the above-mentioned Patent Document 1, the washing motor is of the...
