Definitions
- the present invention relates to a washing machine designed to efficiently use an induction motor.
- An induction motor is an AC motor that is driven by a rotating magnetic field generated by a coil that flows through an alternating current to generate an induced current to the rotor side, and is driven by the interaction between the generated magnetic field and the rotating magnetic field.
- the rotational power generated on the output shaft of such a motor is transmitted to the input shaft of the rotating portion such as the stirring blade or the dewatering tub via the speed reducer via a pair of pulleys and a belt (Patent Document 1).
- the inverter control is a control method in which an alternating current is converted into a direct current and then converted into an alternating current of an arbitrary frequency to drive the motor (Patent Document 2).
- the frequency conversion control type washing machine can be set to a frequency of efficient operation, since the control system is complicated, there is a disadvantage that the overall price is high.

- the inertia rotation time is a work unit, and the control of the reverse rotation of the rotating portion is repeatedly performed for each of the work units.
- the predetermined driving time in this case is preferably set to be longer than the time when the speed ratio of the transmission is changed from the maximum to the minimum.
- the torque on the driven side can be multiplied in the low-efficiency low-rotation region of the induction motor by the transmission, and the low-rotation region can be quickly passed. Then, by the torque multiplied, the cleaning power to the laundry after starting is increased, and then the power consumption is reduced by rapidly moving to the side of the high rotation region where the motor efficiency is high. Since the washing machine repeatedly performs the unique operation of forward/reverse rotation in a short time, the above effects are repeated. Therefore, according to the present invention, even a low-cost structure using an induction motor can be realized as Efficient operation in the case of a frequency converter.
- the inertia weight only increases the portion of the component parts required for the variable structure as compared with the structure using the fixed type pulley. Therefore, the moment of inertia when the laundry is pulled and rotated is also increased, and the cleaning effect can be further improved.
- the time until the stop is also lengthened as the inertial weight increases.
- the rotating portion is reversed by the same inertia stopping time as the fixed type pulley, it will be reversed during the inertia rotation.
- the inertial weight can be used.
- the induced inertial rotation is effectively applied to the cleaning. Further, as long as such a setting is adopted, since the induction motor has a speed of 0 every time, the torque multiplication effect at the time of starting can be utilized every time.
