Washing machine and control method thereof

In accordance with an aspect of the present disclosure, a washing apparatus including a main motor configured to generate a rotational force and provide the rotational force to a washing shaft; a coupling disposed above the main motor and selectively transmitting the rotational force of the main motor to a spin-drying shaft by vertically moving; a clutch motor configured to generate a tensile force in a radial direction of the coupling; a clutch lever configured to decouple the main motor from the coupling by moving the coupling upward using the tensile force of the clutch motor; and a controller configured to rotate the main motor in a mode switching section from a spin-drying mode, in which the coupling is coupled to the main motor, to a washing mode, in which the coupling is decoupled from the main motor, or from the washing mode to the spin-drying mode.

Washing apparatus and controlling method thereof

The present invention relates to a washing machine and a control method thereof. The method of controlling the washing machine may include accelerating a motor, and detecting a weight of laundry inside a washing tub; and providing a force in a direction opposite to a rotating direction of the motor to the motor, and decelerating the motor.

Washing machine and method for controlling same

A washing machine includes an alternating current (AC) motor which generates torque, a clutch assembly which selectively transfers the torque to a rotating tub and a pulsator, a speed detector which detects a rotary speed of the clutch assembly, and a controller configured to repetitively perform operating and stopping the operating of the AC motor based on a predetermined target speed and the rotary speed of the clutch assembly in a spin-drying operation. The controller gradually increases the torque of the AC motor while operating the AC motor.

Washing machine and method of controlling the same using an AC motor

A washing machine includes a rotary tub; a motor to rotate the rotary tub; a velocity sensing unit to sense rotational velocity of the motor; and a controller to compare a command value of the motor with a predetermined limit value, when the rotational velocity of the motor is less than a spin-drying velocity during spin-drying, to determine whether the motor is overloaded and to control driving of the motor in response to the determination.

Washing machine and method for controlling the same

A method of controlling a washing machine includes detecting a water level in a drum when a barrel cleaning is executed; supplying or draining water according to the detected water level such that a water level reaches a reference water level; soaking an interior of the drum in water; draining water after the interior of the drum is soaked in water; and detecting clothes contained in the drum by rotating the drum.

Method of controlling washing machine

A washing machine and a control method thereof, capable of reducing noise by performing a zero-current control during the braking of a motor, and checking whether a vibration sensor is installed on a tub in a weight detection state in the beginning of a spin-drying. The zero-current control is performed by driving a current regulator with a command current set to '0 A', so that the current flowing at the motor decreases and thus noise is reduced. In a washing machine having a vibration sensor fixedly attached to a tub, a fixation state of the vibration sensor with respect to the tub is checked in advance by use of measurement data of the vibration sensor at a weight detection stage in the beginning of the spin drying so that the frame touch caused by an erroneous detection of vibration or a failure of vibration detection may be prevented.

A washing machine and a control method thereof capable of determining whether a driving motor is locked. A pulsator is rotatably mounted in a spin basket, a driving motor generates rotational force, a clutch transmits the rotational force to the pulsator or the spin basket, a driving circuit supplies a driving current to the driving motor, and a control unit controls the driving circuit and the clutch so that the pulsator rotates in a forward or reverse direction and rotation of the spin basket is stopped in a washing or rinsing process. The control unit controls the driving circuit so that a motor lock detection current is supplied to the driving motor, and controls the clutch so that, if a rotating speed of the driving motor is less than a reference speed, the rotational force is transmitted only to the pulsator.

Disclosed herein are a washing machine and a method of controlling the same that are capable of removing bubbles from a door after washing. The washing machine includes a drum and a door to open and close the drum. The method of controlling the washing machine includes determining whether the present operation is a spin-drying operation, and, when the present operation is the spin-drying operation, supplying water to the door to remove residual bubbles from the door.

A method for controlling a washing machine includes comparing a command value of a motor with a predetermined limit value, during spin-drying, to determine whether the motor is overloaded, and controlling driving of the motor in response to the determination. It may be possible to determine a water filling state, an excessive bubble state, or a drainage error state, which may be caused during a spin-drying operation, and to take a proper measure. That is, in the drainage error state, a user is informed of the drainage error. In the water filling state, the spin-drying is normally completed by re-performing the spin-drying operation. In the excessive bubble state, a rinsing or spin-drying operation is added to remove the bubbles. When the bubbles are not removed by the added rinsing or spin-drying operation, the excessive bubble message is displayed to inform a consumer of the excessive bubble state.

A washing machine and a control method thereof in which a tub washing course is safely performed using a sensor to measure vibration of a tub. Since whether or not laundry is present in s drum is sensed while performing the tub washing course, consumption of separate time, water, and energy to sense whether or not laundry is present is not required, and operation of the washing machine is controlled by diagnosing malfunction of the sensor. If plural sensors are installed, a micro-computer is connected to the plural sensors in common through a Serial Peripheral Interface (SPI) communication method or an Inter Integrated circuit (I2C) communication method, thereby reducing costs and volume of wire-harness.
