In addition, the sensor unit 160 may further include a laundry detection sensor (not shown) that detects the state or material of the laundry. The temperature sensor (not shown) senses the temperature and water temperature inside the laundry treatment apparatus 1. When the laundry treatment apparatus is provided with a heater, the temperature of the heater may be sensed. The temperature sensor is provided with a plurality, each installed in a different position to sense the temperature. The level sensor detects the height of the water supplied to the tub. The current sensor may detect a current applied to the motor 135 and the door sensor may detect whether the door is opened or closed.

The motor driving unit 130 applies a current to the motor 135 and controls the motor to rotate. The motor driving unit 130 controls the operation of the motor by converting and applying the power supplied through the power supply unit to the power for the motor 135 to rotate. The motor driver may include an inverter for driving the motor.

The motor driving unit 130 controls the rotation direction, the rotation angle and the rotation speed of the motor 135 according to the control command of the controller 110. The motor driving unit 130 controls the motor 135 to operate differently according to the set washing course and washing, rinsing, and dehydration. The motor driving unit 130 controls the rotation direction, the rotation angle and the rotation speed of the driving unit differently, so that the washing water in the drum forms a specific type of water flow.

The water supply unit 150 allows the cold and warm water to be supplied according to the washing and rinsing strokes. The water supply unit 150 controls the opening and closing of the water supply valve (not shown) to control the water supply amount.

The water supply unit 150 causes the water to be continuously supplied or stopped after the predetermined time water supply depending on the time at which it is performed, that is, whether it is being washed or rinsed or the operation pattern of the drum.

The drain 140 is disposed below the tub and includes a drain pipe (not shown) for forming a drain flow path and a drain pump (not shown) for pumping the wash water flowing through the drain flow path to the outside of the laundry treatment apparatus 1. It may include. The drain 140 controls the opening and closing of the drain valve (not shown) and controls the operation of the drain pump so that water is discharged to the outside through the drain hose.

The controller 110 controls a series of washing processes of washing, rinsing, dehydration and drying. Hereafter, performing the washing indicates that all operations including washing stroke, rinsing stroke, dehydration stroke, and drying stroke are performed. In the case of drying administration may be applied differently depending on whether the laundry treatment device includes a drying function.

The controller 110 stores the input operation setting in the memory 120 and controls the operation by calling the water level and temperature setting and the operation pattern according to the washing course in response to the data stored in the memory. The controller 110 allows the operation setting or the operation state to be output through the output unit 170.

The control unit 110 controls the water supply unit 150 and the drain unit 140 to perform the water supply and drainage to the tub according to the operation setting, and applies a control command to the motor driving unit 130, according to the operation of the drive unit The drum rotates to allow washing to be performed. In addition, the controller 110 applies a control command to a heater (not shown) so that the heater operates to heat the wash water or to perform a drying operation.

The controller 110 may control the motor driving unit 130 so that the drum operates according to a predetermined pattern, detect the amount of laundry (capacity), and determine unbalance due to tangling of the laundry. For example, the controller 110 may determine the amount of laundry on the basis of the current value measured while the drum rotates, and also determine the eccentricity through the change of the current, in particular, the ripple of the current. The manner of detecting the amount and eccentricity of the laundry may be various embodiments may be used, and the described manner is not limited thereto.

In addition, the control unit 110 allows the inflating operation to solve the tangling of the laundry before the rinsing after washing or before dehydration after rinsing. If the laundry is entangled, there may be a problem that an eccentricity may increase, and a limitation may occur in high-speed rotation during dehydration, so that the inflating operation is performed before proceeding with dehydration.

The controller 110 controls the motor driver to perform the inflating according to the designated operation pattern. In addition, the control unit may control the water supply unit during the inflating operation so as to ease the tangling of the laundry so that the washing water is partially supplied to the washing tank.

The controller 110 may determine the state of the laundry during the inflating operation, and stop the inflating operation and proceed with dehydration even if the set number of times is not reached in response to the state of the laundry.

3 is a view referred to explain the inflating operation of the laundry treatment apparatus according to an embodiment of the present invention.

As shown in FIG. 3, the control unit 110 controls the operation of the drum by applying a control command to the motor driving unit 130.

In particular, when the washing stroke is completed, and the rinsing stroke is started, the control unit 110 allows dehydration to be performed before entering the rinsing stroke.

Before the dehydration operation, the controller 110 may perform a quantity detection or an eccentricity detection. In addition, the controller 110 may entangle laundry, and thus may perform an inflating operation to release the laundry from tangling.

By performing the inflation before dewatering rotating at high speed, the eccentricity is reduced to facilitate high speed rotation.

The controller 110 applies a control command to perform the inflating operation, and the motor driving unit 130 controls the motor 135 to operate according to the designated operation pattern.

As shown in FIG. 4, the inflating operation may be performed.

The inflating operation may be composed of a plurality of motions of a predetermined pattern.

The inflating operation performs a second motion of causing the laundry to flow outward from the inside of the drum by the rotation of the drum, and performs a third motion of causing the laundry to flow from the inner part of the drum to the inside by rotating the drum. Do it. In addition, the inflating operation may operate according to the first motion of repeating the rotation of the drum alternately in the left and right directions before performing the second motion.

When the inflating operation is performed, before the drum is operated, the control unit controls the water supply unit 150 to stop the water supply and additionally supply the wash water. The laundry is tangled to provide additional wash water so that the laundry can be easily loosened. .

The second motion is operated at the third speed S3, and the third motion and the first motion are rotated at the first speed S1.

After the first motion is performed, the controller 110 repeats the set number of times of the second motion and the third motion in one unit, and then proceeds with dehydration.

The control unit 110 performs the second motion and the third motion repeatedly so that tangling of the laundry is easily eliminated.

When the inflating operation is started P1, the first motion is performed during the first period D1, and the second motion and the third motion are repeatedly performed during the second to fifth periods D2 to D5. In the second to fifth sections, each section may be divided into a twenty-first section D21 in which the second motion is performed and a twenty-second section D22 in which the third motion is performed.

In addition, after the second motion is performed in the sixth section D6, the motor is stopped, and in the seventh section D7, the dehydration operation is performed.

During the inflating operation, the control unit 110 determines the state of the laundry on the basis of the eccentric value detected by the sensor unit, and determines whether or not to enter the dehydration. The dehydration is started during the stationary state or the rotational operation and accelerates step by step, and accelerates and progresses above the fourth speed S4.

The controller determines the eccentricity during the third motion during each of the second to fifth periods (P2 to P5), and allows dehydration to proceed when the eccentricity is less than / less than the set value.

In particular, in the washing process of removing contaminants of laundry, the laundry may be entangled by performing an operation that generates the bibim effect.

Accordingly, the inflating can be performed at the finishing stage of the washing administration.

FIG. 4 is a diagram referred to describe an operation for entering dehydration during the inflating operation of FIG. 3.

As shown in FIG. 4, the inflating operation is composed of a combination of first to first motions.

During the laundry administration, when the washing is completed, the control unit causes the inflating operation to be performed.

When the inflating operation is started (P1), the drum operates while stirring left and right at the first speed S1 according to the first motion during the first section D1.

In addition, the second motion is performed at the third speed during the twenty-first period D21, and the third motion is performed at the first speed during the twenty-second period D22.

During the third motion, the controller detects the eccentricity based on the data input from the sensor unit (P2), and, according to the eccentricity, may immediately start the dehydration operation (D12), as shown. The eccentricity may be detected in the step of decelerating after maintaining the first speed for a predetermined time in the 22nd section D22.

When the eccentricity satisfies the set value, the controller 110 maintains the second speed S2, which is the current rotation speed, for a predetermined time and accelerates the rotation without reducing the rotation speed.

At this time, by accelerating while maintaining the rotation state without stopping the motor it is possible to shorten the time required for the acceleration step during the dehydration operation.

In particular, dehydration short-circuit phenomenon occurs due to vibration in the process of reaching a constant speed at low speed during dehydration, and dehydration short-circuit occurs as the dehydration short-circuit phenomenon starts dehydration past the speed section that occurs. It is possible to avoid wasting time, water and energy during repeated entry. The dehydration short circuit is likely to occur at or below the second speed S2.

5 is a view referred to for explaining the inflating operation and dehydration operation of the laundry treatment apparatus according to an embodiment of the present invention.

As shown in FIG. 5, dehydration may be performed in response to the state of the laundry during the inflating operation.

During the first interval, the first motion is performed at the first speed S1, and while the third motion and the first motion are repeatedly performed, inflating is performed according to the second and third motions in the second interval D2. And after performing the second motion in the third section (T11), while performing the third motion, the controller detects the eccentricity based on the detected data.

If the measured eccentricity is less than / less than the set value, the subsequent inflating operation is canceled and the dehydration operation (D7 ') is immediately started.

While decelerating at the first speed by performing the third motion, when the eccentricity is detected (P3), the dehydration operation is started. After the second rotational speed is maintained in the eighth section D8 for a predetermined time, the second rotation speed is accelerated to the fourth speed S4, and then, in the ninth section D9, dehydration is performed at a fourth speed or more.

At this time, as the dehydration operation is performed, the drainage unit starts draining. Accordingly, drainage waiting time can also be reduced.

FIG. 6 is a view referred to explaining the rotational speed and the vibration generated during the inflating operation of the laundry treatment apparatus according to an embodiment of the present invention, and FIG. 7 is used to describe the load torque for the inflating operation of FIG. 6. It is a figure.

As shown in FIG. 6, during the inflating operation, the rotational speed L11 of the motor is increased to the first speed and then decreased while performing the third motion.

After the rotational speed of the motor increases to the first speed and maintains the first speed for a predetermined time, while decelerating, the controller calculates an eccentricity based on the sensed current value and determines whether or not dehydration proceeds.

The vibration L12 sensed while the third motion is performed rapidly increases in the acceleration section of the third motion to indicate the peak P11.

In addition, while accelerating while performing the second motion, the vibrations represent the second pits P12.

At this time, the vibration is the vibration of the tub.

The controller may predict the vibration of the dehydration operation based on the vibration detected during the inflating operation.

As shown in FIG. 7, the value for the load torque may be estimated using the motor torque equation according to the following equation 1 according to the vibration generated during the inflating operation.

Te is the driving torque and T _L Is the load torque, Bm is the friction coefficient, Jm is the inertia coefficient, and Wm is the speed.

Accordingly, it can be seen that the load torque L13 increases in the acceleration section P14 where vibration is large.

The load torque during the dehydration operation can be estimated based on the correlation between the vibration and the load torque.

The controller may determine whether to enter the dehydration based on the eccentricity detected during the third motion. In addition, the controller may determine the load torque based on the vibration caused by the eccentricity, and determine whether or not to enter the dehydration.

8 is a view referred to for explaining the change in vibration according to the number of inflating operation of the laundry treatment apparatus according to an embodiment of the present invention.

The inflating operation is performed in the first to the first motions.

FIG. 8A is a diagram illustrating the relationship between the number of inflating and the vibration when the inflating is performed in the first motion, and FIG. 8B is a diagram showing the case in which the inflating is performed in the second motion. A diagram showing the relationship between the number of inflation and vibration.

As described above, the inflating operation is performed once by performing the initial first motion, and then repeatedly performing the second and third motions.

The second motion is an operation for eliminating tangling of the laundry and the third motion is an operation for determining the state of the laundry.

In the case of repeating the first motion, the vibration is greatly reduced at the time of performing the first time, but after the second time, the vibration is not large and the vibration is maintained at 10 or more.

On the other hand, when the inflating is performed through the second motion, the vibration is greatly reduced at the first time, and the amplitude of the vibration is decreased from the second time, but the vibration is reduced rather than the case where the first motion is repeated before.

Accordingly, rather than repeating the first motion, the second motion is repeated after the first motion is performed once, and the dehydration can be easily performed by detecting an eccentricity in the third motion to determine whether or not to enter the dehydration.

9 is a flowchart illustrating a control method of a laundry treatment apparatus according to an embodiment of the present invention.

As shown in FIG. 9, the laundry treatment apparatus starts a set operation.

The laundry treatment apparatus detects an amount of laundry, that is, a quantity of laundry (S310), performs a first motion and a fourth motion (S320, S330), and performs laundry (A). The first motion and the fourth motion are operations for decontaminating laundry.

Washing is performed and the inflating operation (B) to eliminate the tangling of the laundry in the step of finishing.

The controller controls the water supply so that water is additionally supplied in the state in which the drum is stopped (S340). By additionally supplying the wash water, the tangles of the laundry can be more effectively resolved.

After the additional water supply, after performing the same first motion (first motion) as washing once, after performing the second motion (second motion) to solve the tangling of the laundry, the third motion (third motion) is performed. Perform. At this time, the eccentric is sensed during the third motion, and the load torque according to the vibration is calculated.

The control unit determines whether the eccentricity is less than or equal to the set value, and repeats the second and third motions according to the inflated by the set number n (S390).

Specifically, the control unit determines whether or not to enter the dehydration by calculating the load torque value of the vibration that can occur according to the eccentricity.

If the eccentricity does not satisfy the condition even after repeating the second and third motions in the inflated motion, the controller adds the second motion once for inflated motion and stops the motion and accelerates the rotational speed. Dehydration is performed (S420).

When the first dehydration is completed, the second dehydration is performed (S430).

On the other hand, if the eccentricity is less than the set value, the dehydration proceeds immediately regardless of the remaining inflated operation (S410). The controller proceeds with dehydration, maintains the rotational speed as it is while performing the third motion, and then accelerates to perform the first dehydration in the second speed section. The second speed section is a speed section that is faster than the first speed section as part of the first speed section.

After the first dehydration, the second dehydration is performed at a third speed section that is faster than the second speed section (S430). Primary dehydration is a preliminary dehydration section and secondary dehydration is a main dehydration section.

Accordingly, by checking the state of the laundry while performing the inflating operation (B) to determine whether to start the dehydration operation (C), if it is determined that the laundry is tangled, the unnecessary inflating operation is not repeated immediately. Dehydration can proceed. Accordingly, by not performing unnecessary operations, washing time can be reduced, water consumption can be reduced, and energy waste can be prevented.

Although the above has been illustrated and described with respect to preferred embodiments of the present invention, the present invention is not limited to the above-described specific embodiments, and the present invention is not limited to the scope of the present invention as claimed in the claims. Various modifications can be made by those skilled in the art, and these modifications should not be individually understood from the technical spirit or the prospect of the present invention.
