Description

Controlling method of clothing treatment device {Controlling Method of LAUNDRY TREATING APPARATUS}

The present invention relates to a control method of a laundry treatment apparatus. More specifically, the present invention relates to a control method of a laundry treatment apparatus capable of reducing washing time by preventing rotation of a drum in a rinsing process.

In general, the clothes treating apparatus refers to a device capable of washing, drying or washing or drying clothes. The garment treatment apparatus may perform only a washing or drying function, or may perform both washing and drying.

In addition, recently, a steam supply device is provided, and a washing machine having a refresh function such as wrinkle removal, odor removal, and static electricity removal of clothes and the like has been widely used.

When the clothes treating apparatus is equipped with a washing machine, a washing stroke for removing foreign matters of clothes, a rinsing stroke for separating foreign matters and detergents of clothes, and a dehydration stroke for removing moisture from clothes are performed.

Conventional clothes handling apparatus has been derived by stirring the drum in the laundry administration or by intermittently rotating the drum in one direction to provide the stretching force and friction force to the clothes rub the clothes with detergent and water.

In the rinsing cycle, the water was resupplied and the drum was rotated to remove foreign matters and detergents from the clothes, and the water was drained to discharge the foreign matters and detergents to the outside of the clothes treatment apparatus.

In the dehydration stroke, the drum was rotated at high speed to provide strong centrifugal force to the clothes to remove moisture from the clothes.

Meanwhile, the conventional clothing treatment apparatus prevents excessive vibration by performing a process of detecting an unbalance of clothing by intermittently rotating a drum before entering a dehydration stroke.

In addition, the conventional clothing treatment apparatus to remove the moisture of the clothes by rotating the drum at a high speed before the water in the rinsing stroke. This is to prevent the contamination of the re-supplied water by discharging the water and the foreign substance dissolved in the detergent remaining in the washing process or the previous rinsing process from the clothes.

Therefore, the conventional clothing processing apparatus performs a process of detecting unbalance of clothing by intermittently rotating the drum even before starting the rinsing stroke, and in the case where the rinsing stroke is repeated a plurality of times, the process of detecting the unbalance is also plural. Was performed twice.

This conventional clothes treatment apparatus was able to prevent excessive vibration in advance in the rinsing stroke or dehydration stroke. However, since the unbalance should always be detected in the rinsing stroke or the dehydrating stroke, there was a problem in that the washing time was delayed.

Stirring (30) from side to side, or rotated in one direction can be performed washing, rinsing, dehydration.

Figure 4 shows a variety of drum driving motion utilized in the control method of the washing stroke, rinsing stroke, and the like of the present invention washing machine.

Drum driving motion means a combination of the rotational direction and the rotational speed of the drum, the clothing located inside the drum by the drum driving motion is the fall direction, the dropping time is different and therefore the flow of clothes in the drum is different You lose. The drum driving motion is implemented by controlling the drive unit.

Since the clothes are raised by the lift provided on the inner circumferential surface of the drum when the drum is rotated, the shock applied to the clothes can be changed by controlling the rotation speed and the rotation direction of the drum. That is, mechanical forces such as friction between clothes, friction between clothes and wash water, and dropping impact of clothes can be varied. In other words, it is possible to vary the degree of tapping or rubbing clothes for washing, and to vary the degree of dispersion or flipping of the clothes.

Therefore, the present invention can process the garment with the optimum mechanical force by varying the drum driving motion according to the type of clothes, the degree of contamination of the clothes, each step, each step of forming each stroke. This can improve the washing efficiency of the clothes.

In order to implement such various drum driving motions, the driving unit 40 is preferably a direct type motor. That is, the stator of the motor is preferably the tub 20 is fixed to the rear, the rotor of the motor is rotated to drive the drum 30 directly. This is because by controlling the rotation direction, torque, etc. of the motor, it is possible to immediately control the drum drive motion by preventing the time delay or backlash (maximum).

4 (a) is a view showing a rolling motion (rolling motion). The rolling motion is a motion in which the driving unit 40 rotates the drum 30 in one direction, and the clothes on the inner circumferential surface of the drum fall to the lowest point of the drum at a position less than about 90 degrees in the rotation direction of the drum.

That is, when the driving unit 40 rotates the drum at about 40 RPM, the garment located at the lowest point of the drum 30 rises a predetermined height along the rotational direction of the drum 30 and is less than about 90 degrees in the rotational direction at the lowest point of the drum. As it rolls in position, it flows to the lowest point of the drum. Visually, when the drum rotates clockwise, the clothing rolls continuously in three quadrants of the drum.

The clothing is washed through the rolling motion through friction with water, friction between clothing, and friction with the drum inner circumferential surface. In addition, the motion of the clothing is sufficiently generated through such a motion, thereby obtaining the effect of gently rubbing the clothing.

Here, the drum RPM is determined in relation to the radius of the drum. That is, as the RPM of the drum increases, centrifugal force is generated on the clothes in the drum. Due to the difference in size between the centrifugal force and gravity, the flow of clothing in the drum is changed. Of course, the rotational force of the drum and the friction between the drum and the garment should also be taken into account.

Therefore, in the rolling motion, the RPM of the drum is determined so that the centrifugal force and the frictional force are less than the gravity 1G.

FIG. 4B is a diagram showing tumbling motion.

The tumbling motion is a motion in which the driving unit 40 rotates the drum 30 in one direction but the clothes on the inner circumferential surface of the drum fall to the lowest point of the drum at a position of about 90 to 110 degrees of rotation of the drum. The tumbling motion is a drum driving motion that is generally used when washing and rinsing because the mechanical force is generated only by controlling the drum to rotate in one direction at an appropriate RPM.

That is, the clothing put into the drum 30 is located at the lowest point of the drum 30 before the driving unit 40 is driven. When the driving unit 40 provides torque to the drum 30, the drum 30 rotates, and the lift provided on the inner circumferential surface of the drum moves the clothes from the lowest point in the drum to a predetermined height. If the driving unit 40 rotates the drum 30 to about 46 RPM, the clothes fall in the lowest point direction of the drum at a position of about 90 to 110 degrees in the rotational direction at the lowest point of the drum.

The tumbling motion generates a greater centrifugal force than the centrifugal force in the rolling motion, but the RPM of the drum is determined to generate less than the gravity.

Visually, tumbling motion is a form in which the drum moves from the third quadrant to a part of the second quadrant at the lowest point of the drum when it is rotated clockwise and then falls off the inner peripheral surface of the drum to the lowest point of the drum.

Thus, the tumbling motion allows the garment to be washed by the impact force caused by friction and drop with water, thereby providing a greater mechanical force to the garment than the mechanical force in the rolling motion. And, because the motion to fall out of the drum to some extent, there is an effect of separating the tangled clothing and to distribute the clothing.

4 (c) is a diagram showing step motion. The step motion is a motion in which the driving unit 40 rotates the drum 30 in one direction but the clothes on the inner circumferential surface of the drum fall from the highest point in the drum's rotational direction (a position of about 180 degrees) to the lowest point of the drum.

When the driving unit 40 rotates the drum 30 at about 60 RPM or more, the garment can rotate without falling by centrifugal force, and the step motion is performed at a speed such that the garment does not fall from the drum inner circumferential surface due to the centrifugal force. After the drum is rotated, the drum is braked to maximize the impact force on the garment.

In the step motion, the driving unit 40 rotates the drum at a speed (about 60 RPM or more) at which the clothes do not fall from the outer circumferential surface of the drum by centrifugal force, and then the clothes are positioned near the highest point of the drum (180 degrees in the rotational direction). The reverse torque is controlled to supply the drum 30.

Therefore, since the clothes are raised in the rotational direction of the drum at the lowest point of the drum 30, the clothes fall from the highest point of the drum 30 to the lowest point at the moment when the drum stops due to the reverse torque of the driving unit 40. Is a motion of washing clothes by the impact force caused in the process of falling to the maximum fall of the clothing inside the drum. The mechanical force generated by such step motion is larger than the rolling motion or tumbling motion described above.

Visually, the step motion is a form in which the drum moves clockwise from the lowest point of the drum to the highest point of the drum after passing from the third quadrant to the highest point of the drum and then suddenly falls off the inner peripheral surface of the drum to the lowest point of the drum. Therefore, since the distance falling in the drum in the step motion is the largest, it is possible to provide a mechanical force more effectively in case of small amounts.

On the other hand, the drive unit 40 is preferably reversed braking for braking the drum. The reverse braking is a method of braking the motor by generating a rotational force in a direction opposite to the direction in which the motor is rotating. The phase of the current supplied to the motor can be reversed to induce a rotation force opposite to the direction in which the motor is rotating, and the reverse phase braking enables the braking of the motor. Thus, the reversed braking is the most appropriate braking method for the step motion which gives a strong impact on the garment.

Thereafter, the driving unit 40 applies torque to the drum 30 again to raise the garment at the lowest point of the drum to the highest point. That is, after the torque is applied to rotate clockwise, the torque is momentarily stopped by applying the torque to rotate in the counterclockwise direction and then the torque is applied to rotate in the clockwise direction.

As a result, the step motion is a motion of washing the laundry by friction with the laundry water introduced into the through-hole provided in the drum inner wall during the rotation of the drum, washing the clothes by dropping when the clothing is located at the top of the drum.

4 (d) is a view showing swing motion. The swing motion is a motion in which the driving unit 40 rotates the drum 30 in both directions, and the clothes fall after passing through a 90 degree point in the rotation direction of the drum.

That is, when the driving unit 40 rotates the drum 30 in the counterclockwise direction at about 40 RPM, the garment located at the lowest point of the drum 30 rises a predetermined height in the counterclockwise direction. In this case, the driving unit stops the rotation of the drum after passing through the counterclockwise 90 degree point of the drum so that the clothes fall in the direction of the lowest point of the drum after passing the counterclockwise 90 degree point of the drum.

Thereafter, the driving unit 40 rotates the drum 30 clockwise at about 40 RPM and drops the clothes to a predetermined height in a clockwise direction along the rotational direction of the drum. Meanwhile, the driving unit 40 stops the rotation of the drum after the clothes have passed the clockwise 90 degree point of the drum so that the clothes fall in the direction of the lowest point of the drum at the position which has passed the clockwise 90 degree point of the drum.

In other words, swing motion is a motion in which the drum rotates in one direction and stops and the rotation and stops in reverse direction. Visually, the clothes rise from the three quadrants of the drum to a portion of the second quadrant, and then drop gently. It can be said to be a form that repeatedly rises up and falls smoothly.

At this time, the braking of the driving unit 40 is to minimize the load generated on the driving unit 40 by using the power generation braking, and to minimize the mechanical wear of the driving unit 40, it is possible to adjust the impact applied to the clothing.

The power generation braking is a braking method in which the motor acts as a generator by rotational inertia when the current applied to the driving unit is turned off. When the current applied to the motor is turned off, the direction of the current flowing through the coil of the motor is opposite to the direction of the current before the power is turned off. Therefore, a force (Fleming's right hand law) acts in a direction that hinders the rotation of the motor, thereby braking the motor. The power generation braking does not brake the motor differently from the reverse braking, but smoothes the rotational direction of the drum.

Therefore, the swing motion visually becomes a form in which the clothes flow in the form of eight characters lying sideways over the third and fourth quadrants of the drum.

4 (e) is a view showing scrub motion. The scrub motion is a motion in which the driving unit 40 rotates the drum 30 in both directions, and the clothes fall at a position of about 90 degrees or more in the rotational direction of the drum through reverse braking.

That is, when the driving unit 40 rotates the drum 30 counterclockwise to about 60 RPM or more, the garment located at the lowest point of the drum 30 rises a predetermined height in the counterclockwise direction. At this time, the driving unit is to stop the rotation of the drum by providing a reverse torque to the drum after the clothing passes the position of about 90 degrees counterclockwise of the drum. Then, the clothing on the inner circumferential surface of the drum drops rapidly.

Thereafter, the drive unit 40 rotates the drum clockwise at about 60 RPM to raise the dropped clothes to a predetermined height in the clockwise direction. The drive unit 40 stops rotation of the drum by providing reverse torque to the drum 30 when the clothing passes through the clockwise 90 degree position of the drum. Therefore, the clothes on the inner circumferential surface of the drum fall to the lowest point of the drum at a position 90 degrees or more clockwise of the drum.

Accordingly, the scrub motion washes the clothes by causing the clothes to fall sharply at a predetermined height. On the other hand, the drive unit 40 is preferably reversed braking for braking the drum.

Since the direction of rotation of the drum is sharply switched, the garment does not deviate greatly from the inner circumferential surface of the drum, thereby achieving a very strong rubbing effect. The scrub motion is a form in which the clothing that has moved to a portion of the second quadrant after the third quadrant drops sharply, moves again to the portion of the first quadrant after passing through the fourth quadrant. Therefore, it can be said that the garment which rises visually descends along the inner peripheral surface of a drum.

Figure 4 (f) is a view showing the filtration motion (filtration motion). The filtration motion is a motion in which the driving unit 40 rotates the drum 30 so that the clothes do not fall off the inner circumferential surface of the drum by centrifugal force, and sprays the washing water into the drum.

That is, the filtration motion is in close contact with the inner circumferential surface of the drum after the clothes are unfolded, so that water is sprayed into the drum while the water is discharged to the tub 20 through the through holes of the clothes and the drum by centrifugal force. Therefore, the filtration motion expands the surface area of the garment in contact with the wash water, while allowing the wash water to penetrate the clothes, thereby providing an effect of evenly supplying the wash water to the clothes.

The method of spraying water on the drum in the filtration motion may be implemented by circulating and spraying the washing water stored in the tub using a circulation passage and a circulation pump.

On the other hand, the filtration motion may proceed to rotate only the clothes are in close contact with the inner peripheral surface of the drum without spraying water.

In addition, the filtration motion may be implemented by spraying clean water supplied from an external water source without circulating the wash water stored in the tub. Spary Rinse motion). Since the spray rinse motion uses clean water, the spray rinse motion is suitable for a stroke requiring rinsing.

4 (g) is a diagram showing a squeeze motion. The squeeze motion repeats the operation of separating the clothes from the inner peripheral surface of the drum by lowering the rotational speed of the drum 30 after the drive unit 40 rotates the drum 30 so that the clothing does not fall from the inner peripheral surface of the drum by centrifugal force And spraying water into the drum during rotation of the drum.

That is, the filtration motion is continuously rotated at a speed at which the garment does not fall off the inner circumferential surface of the drum, but the squeeze motion changes the rotation speed of the drum to repeat the close and close contact with the inner circumferential surface of the drum 30. There is.

The process of spraying water into the drum 30 during the filtration motion and the squeeze motion may be implemented by the circulation passage and the circulation pump.

Hereinafter, with reference to Figures 4 to 6, the drum driving motion and drum rpm control applied in the washing stroke, rinsing stroke, dehydration stroke of the present invention clothes handling apparatus will be described.

Figure 5 also shows a graph of the change in the drum RPM in the rinsing stroke.

Figure 5 (a) shows a rinsing stroke of the conventional clothing treatment apparatus, Figure 5 (b) shows a rinsing stroke of the laundry treatment apparatus of the present invention.

Referring to Figure 5 (a), the conventional laundry treatment apparatus performs a wet bubble detection step (step a) to detect the amount of clothing when the washing cycle is finished and all the water is drained to start the rinsing stroke. The control unit of the conventional clothing treatment apparatus determines the amount of water to be injected into the drum based on the detected amount of wet foam. The rolling motion or the tumbling motion may be repeatedly performed when the amount of the blister is sensed.

Thereafter, the conventional clothing treatment apparatus performs a first unbalance detection step (step b) of detecting whether the clothes are evenly distributed in the drum. The first unbalance detection step is to detect whether excessive vibration is generated inside the drum while intermittently performing a filtration motion or performing a squeeze motion by increasing the rotational speed of the drum higher than the reference RPM. The reference RPM may be set to a rotational speed at which the garment is attached to the drum inner wall.

On the other hand, it is preferable that the rotational speed of the drum does not exceed the excess RPM in the unbalance detection step. The transient rpm may be set to an rpm between the dehydration rpm and the reference rpm. For example, the excessive RPM may correspond to the rpm at which abnormal vibration occurs when raising the rpm of the drum. It may also be a region corresponding to the resonance frequency of the clothes treating apparatus. Thus, in the unbalance detection step, even when the unbalance degree is less than the reference value, it is possible to prevent the misjudgment of the balance degree due to abnormal vibration by raising the drum above the excessive rpm.

The control unit of the conventional clothing treatment apparatus performs a rinsing dehydration step (step C) of raising the rotational speed of the drum to a dewatering RPM, through which centrifugal force can discharge the water, when it is determined that the unbalance degree is less than or equal to the reference value.

The unbalance detection step and the rinsing dehydration step may be performed in the rinsing stroke to discharge the detergent and foreign substances remaining in the garment to the outside of the drum. have.

On the other hand, in the unbalance detection step, if the degree of unbalance exceeds the reference value, the inflation step may be further performed, such as performing a tumbling motion or watering the tub.

The conventional clothing treatment apparatus performs a rinsing water supply step (d step) of supplying water to the tub after stopping the rotation of the drum when the rinsing dehydration step is completed.

In the rinsing water supply step (d step), the drum may be rotated intermittently so that the water supplied to the clothes may be better penetrated or penetrated, for example, a rolling motion or a tumbling motion may be performed.

When the water supply is completed, the conventional clothes treating apparatus performs a rinsing step (step e) of removing the foreign matter or detergent contained in the clothes by rotating the drum. In the rinsing step, the drum may be stirred by rotating from side to side, or may be intermittently rotated in one direction to separate detergent and foreign substances remaining in the garment. For example, rolling motion, tumbling motion, scrub motion, or the like may be performed.

In the rinsing step (step e), the circulation pump 82 is driven to circulate the washing water to maximize the rinsing performance.

When the rinsing step is completed, the conventional clothing treatment apparatus performs a draining step (step f) to discharge the detergent and foreign matter to the outside of the tub.

When the drainage is completed, the conventional clothing treatment apparatus performs a second unbalance detection step (step g) of removing some of the moisture of the clothes while detecting unbalance in the drum again. The second unbalance detection step may be performed in the same manner as the first unbalance detection step (step b).

When the unbalance degree is less than the reference value, the control unit of the conventional clothing treatment apparatus performs the rinsing dehydration step (c) again to discharge foreign substances, detergent, and water remaining in the garment to the outside of the drum. The rinsing dehydration step (c), which is carried out after the draining step (f), may be longer than the rinsing dehydration step (c) before the rinsing water supply step.

In this case, the first rinsing dehydration step (c) and the second rinsing dehydration step (h) may remove the washing water and foreign substances discharged by the drain pump from the tub.

As a result, the unbalance detection step (B, G) or the rinsing dehydration step (C, H step) in the rinsing stroke maintains the clothes attached to the drum by rotating the drum above the standard RPM, and the wet bubble detection step. B. In the rinsing water supply stage, the rinsing stage, and the draining stage, the drum rotates to less than the reference RPM so that the clothing is repeatedly attached and detached from the drum inner wall. In addition, the conventional clothing treatment apparatus repeats stopping and rotating the drum for the time T1 at which the rinsing stroke is started and completed, and always performs an unbalance detection step before entering the rinsing dehydration step.

Therefore, the conventional clothing treatment apparatus has a problem that the time required for the rinsing stroke is delayed by the time for performing the unbalance detection step, and as a result, the washing time is delayed. In addition, the conventional clothing processing apparatus has a problem that the energy efficiency is reduced while the power is consumed while performing the unbalance detection step.

In addition, the conventional clothing treatment apparatus has a problem that excessive vibration is generated inside the drum by stopping the drum rotation or changing the rotation direction, the excessive load on the drive unit 40.

Figure 5 (b) shows the rinsing stroke of the laundry treatment apparatus of the present invention based on the RPM of the drum.

The rinsing stroke of the laundry treatment apparatus according to the present invention may be the same as performing a wet bubble detection step (step a), an unbalance detection step (step b), and a rinsing dehydration step (step c) in the conventional laundry treatment device after the washing stroke. .

However, the laundry treatment apparatus of the present invention maintains the rotational speed of the drum at a reference rpm or higher even after the rinsing dehydration step is completed after the rotational speed of the drum is increased to the dehydration RPM in the first rinsing dehydration step (step c). .

The clothes treating apparatus of the present invention performs a rinsing water supply step (d step), the rinsing step (e step) and the draining step (step f) while maintaining the rotation speed of the drum at a reference rpm or more.

In other words, the present invention, while performing the unbalance detection step (b) and the rinsing dehydration step (c), while maintaining the state that the clothes are attached to the inner wall of the drum while the unbalance degree is below the reference value, A rinsing water supply step (d step), the rinsing step (e step) and the draining step (step f) may be performed.

On the other hand, the laundry treatment apparatus of the present invention does not stop the rotation of the drum even if the first rinsing dehydration step (step c) is completed. Therefore, the control unit P of the present invention laundry treatment apparatus may open the water supply valve after detecting the RPM of the drum reaches the reference RPM or decelerated below the excessive RPM after the first rinsing dehydration step.

In addition, the control unit (P) of the laundry treatment apparatus according to the present invention detects that the water level sensor 90 in the drainage step (f) step that all the water in the tub 20 is discharged, or that all of the discharged When it is detected that the corresponding reference water level is reached, the driving unit 40 may be controlled to immediately increase the rotational speed of the drum 30.

Thus, the laundry treatment apparatus of the present invention can perform the water supply and drainage at a suitable time even if each step of the rinsing stroke is not divided by the rotational speed of the drum.

In addition, the laundry treatment apparatus of the present invention may perform a second rinsing dehydration step (step h) to raise the rpm of the drum to the dewatering rpm as soon as the draining step (step f) is completed. This is because the clothes are kept evenly attached to the drum from the rinsing dehydration step (step c) performed before the rinsing water supply step.

Therefore, the laundry treatment apparatus of the present invention may omit the second unbalance detection step (step G) in the rinsing step, and thus shorten the time required for the rinsing stroke. Specifically, if the time required for the rinsing administration of the conventional clothing treatment apparatus is t1, the time required for the rinsing administration of the laundry treatment apparatus of the present invention is t2, the time can be reduced by t3.

In addition, the laundry treatment apparatus of the present invention is a water supply in the state of maintaining the drum at the reference rpm or more when performing the rinsing water supply step (d step), the rinsing step (e step), the draining step (f step) By operating only the valve or drain pump, not only can the algorithm be simplified, but the load on the drive can be greatly reduced.

In addition, the laundry treatment apparatus of the present invention can greatly reduce power consumption required by the driving unit or by omitting the driving unit to change the direction in which the drum is rotated.

Furthermore, the clothes treating apparatus of the present invention reduces vibrations and noises because the clothes are fixed inside the drum, and can block the occurrence of an error in the dehydration step or the dehydration stroke.

On the other hand, the present invention, the laundry treatment apparatus may be defined as the wet bubble detection step (a) or the unbalance detection step (b) occurs when the drum is stopped rotating, or the rotation direction of the drum is switched, it is an intermittent rotation step. have.

In addition, since the rotation of the drum is not stopped from the first rinsing dehydration step to the second rinsing dehydration step in the laundry treatment apparatus of the present invention, it may be defined as a continuous rotation step.

On the other hand, most washing courses and options of the clothes treatment apparatus generally perform a rinsing cycle a plurality of times to ensure complete removal of foreign substances and detergents.

Therefore, the effect can be further maximized when the rinsing cycle is repeated a plurality of times.

Figure 6 shows a graph on the basis of the rpm of the drum when the rinsing stroke is performed a plurality of times.

FIG. 6 (a) shows a case where a rinsing stroke is performed a plurality of times in a conventional clothes treating apparatus, and FIG. 6 (b) shows a case where a rinsing stroke is performed a plurality of times in a laundry treatment apparatus according to the present invention.

Referring to Figure 6 (a), the conventional flow treatment apparatus may perform a first rinsing stroke to perform a rinse once and then a second rinsing stroke to perform one more time.

At this time, the conventional clothing treatment apparatus may perform the first row stroke including the second rinsing dehydration step (h) in the wet bubble detection step (step a) and repeat the step. In other words, in the conventional flow treatment apparatus, since the rotation of the drum is stopped when the first rinsing stroke is completed, the wet rinsing dehydration step (c) and the rinsing water are performed by performing the wet bubble detection step (a) and the unbalance detection step (b). Step (d) must be performed.

In other words, each time the rinsing stroke is performed a plurality of times, the wet bubble detection step (a) or the unbalance detection step (b) should be performed more repeatedly by that, which corresponds to the fact that washing is delayed and energy consumption is high. do.

Referring to FIG. 6 (b), the apparatus for treating clothes of the present invention may perform a first rinsing stroke for rinsing once and a second rinsing stroke for performing one more rinsing.

The first rinsing stroke of the laundry treatment apparatus of the present invention may be the same as that of FIG. 5 (b), but the rinsing water supply step (d) starts immediately after the rinsing step (e) and the draining step ( f), rinsing dehydration step (h) can be performed. In other words, the laundry treatment apparatus of the present invention may omit performing the wet bubble detection step and the unbalance detection step during the second rinsing stroke.

The laundry treatment apparatus of the present invention does not decelerate the drum rotation speed below the standard rpm until the rinsing stroke is completely completed after the rinsing stroke starts and passes the unbalance detection step. Therefore, even when the first rinsing stroke is finished, since the clothes are evenly attached to the inner wall of the drum, the second rinsing stroke can be started by detecting that the rpm reaches the reference rpm or falls below the excessive rpm. .

As a result, more time t6 can be saved and energy efficiency can be increased by that than when performing a rinse stroke once.

In other words, the more the rinsing stroke is performed in the laundry treatment apparatus of the present invention, the washing time can be greatly saved, and the energy efficiency can be greatly increased.

Figure 7 is a graph showing the entire stroke of the laundry treatment apparatus according to the present invention on the basis of the rpm of the drum.

The laundry treatment apparatus of the present invention may perform a raisins detection step when a washing course is performed.

The raisins detection step may be a step of sensing the weight of the clothing itself before moisture is in contact with the clothing, and the control unit (p) performs a rolling motion, a tumbling motion, and the like by detecting the load added to the driving unit. Volume can be detected.

Thereafter, the controller p may set a water supply amount based on the amount of dry matter and then perform a washing operation. The washing operation may be performed by combining at least one of a rolling motion, a tumbling motion, a swing motion, a step motion, a filtering motion, and a scrub motion according to a washing course and an option. Thereafter, the control unit p may terminate the washing operation by opening the drainage pump to discharge the washing water and the detergent.

When the laundry administration is finished, the present invention, the clothes treating apparatus may perform the second rinse dehydration step (c) in the above-described wet bubble detection step (a) or repeatedly perform the rinsing stroke.

At this time, the laundry treatment apparatus of the present invention can always maintain the rotational speed of the drum above the reference speed (rpm) from the unbalance detection step (b) until the end of the rinsing stroke. Therefore, the laundry treatment apparatus of the present invention can always rotate the drum in the filtering motion in the rinsing stroke.

In other words, the laundry treatment apparatus according to the present invention may continuously rotate the drum in one direction so that the clothes are prevented from being separated from the drum in the rinsing stroke, and after the sensing step includes the wet bubble detection step and the unbalance detection step. The drum may be continuously rotated in one direction to prevent the garment from being separated from the drum until at least the end of the rinsing stroke.

In this case, in the rinsing stroke, water may be supplied to the tub or the water of the tub may be drained while the clothes are attached and rotated from the drum.

In addition, when the last rinsing dehydration step in the rinsing cycle, the present invention clothing processing apparatus may perform a dehydration stroke. In the dehydration stroke, a main dehydration step may be performed to increase the drum speed to a high speed rpm (highest rpm, highest speed) which is a higher rpm than a rinse dehydration step. As a result, the moisture remaining in the garment in the dehydration stroke can be removed as much as possible.

In this case, the dehydration stroke may be performed by accelerating the drum in the rinsing dehydration stroke, or may be performed when the rotational speed of the drum reaches the reference rpm or decreases below the excessive rpm in the rinsing dehydration stroke. As a result, sensing the unbalance level or entering the dehydration stroke may be omitted.

As a result, the laundry treatment apparatus of the present invention can continuously rotate the rotative speed of the drum from the rinsing stroke to the end of the dehydration stroke without being decelerated below the reference rpm. To maximize.

8 is a control method of the laundry treatment apparatus according to the present invention, which shows a conventional washing stroke or dehydration stroke newly defined in consideration of a rotation method of a drum.

The laundry treatment apparatus of the present invention may be newly defined as an intermittent rotation step because there is a time when the drum rotates intermittently or the drum stops rotating even when the drum having the unbalance detection step of the rinsing stroke is rotated at a high speed. Since the rotation of the drum is not stopped or the direction of rotation is not changed until the dehydration stroke, the drum can be newly defined as a continuous rotation stage.

Specifically, the raisins detection step and the unbalance detection step in the laundry administration may be defined as a first intermittent rotation step (s1). That is, in the washing stroke, after the first intermittent rotation step, the water supply step (s2) of performing the water supply by opening the water supply valve may be performed. Thereafter, a step of performing washing by performing the drum rolling, tumbling motion, etc. may be defined as a second intermittent rotation step s3. And, it can be seen that the drainage step (S4) is performed to drain the water and foreign matter by opening the drainage pump at the end of the washing administration.

In addition, a wet bubble detection step and a ub detection step of detecting the amount or unbalance of the clothing by intermittently rotating the drum after the draining step after the draining step in the rinsing stroke may be defined as a third intermittent rotation step (s5). Can be.

In addition, the rinsing stroke may be defined as a continuous rotation step s6 from the third intermittent rotation step until the rinsing dehydration step or the end of the dehydration stroke.

The rinsing water supply step (d) and the draining step (f) performed in the continuous rotation step (s6) is performed while rotating the drum 30 to the rotation water supply step (S6-1) and the rotation drainage step (s6-2) Can be defined

As a result, the continuous rotation step (s6) of the laundry treatment apparatus 1 of the present invention continuously rotates the drum so that the rotation of the drum 30 is not stopped or the rotation direction of the drum 30 is prevented from being changed. Can be.

In other words, it may be prevented that the rotation of the drum is stopped or the rotation direction of the drum is not changed after the third intermittent rotation step s5 until the main dehydration stroke is completed.

In addition, the continuous rotation step (s6) of the laundry treatment apparatus of the present invention can maintain the continuous rotation of the drum even if water is supplied or drained to the tub, it is possible to perform the water supply and drainage while the drum is rotating have.

On the other hand, the laundry treatment apparatus of the present invention may not reduce the rotational speed of the drum below the reference speed until at least the rotation drainage step (f, s4) in the rinsing dehydration step (b).

Of course, as described above, the continuous rotation step (s6) to continuously rotate the drum 30 above the reference speed (rpm) from after the third intermittent rotation step until the end of the rinsing stroke or the end of the washing course. Can be.

In the continuous rotation step, the rinsing dehydration step (c) may be immediately performed after the completion of the rotation draining step (s6-2), and the rinsing dehydration step (c) may be the rotation draining step (6-2, f). If the water level of the tub reaches a reference level or less can be performed.

9 compares the performance of the present invention and the conventional laundry treatment apparatus.

Figure 9 (a) shows the ratio of the maximum current value in the first rinsing dehydration step and the second rinsing dehydration step in the rinsing stroke. (Maximum current of the second rinsing dehydration stage / Max. Current of the first rinsing dehydration stage)

Fig. 9 (c) shows the deviation of the power consumption of the conventional clothing processing apparatus and the clothes processing apparatus of the present invention.

Conventional clothes treatment apparatus has a large deviation of the maximum current value consumed in the second rinsing dehydration step on the basis of the maximum current value consumed in the first rinsing dehydration step, the present invention, the laundry treatment apparatus is the maximum consumed in the first rinsing dehydration step The deviation is small based on the current value.

This means that during the rinsing step in the conventional clothes handling apparatus, more instantaneous energy is required to rotate the drum due to agglomeration or twisting of the clothes in the drum.

However, the clothes treating apparatus of the present invention means that the energy required to rotate the drum is almost uniform because the clothes are not separated inside the drum even after the continuous rotation step or the rinsing stroke and the dehydration stroke.

Since the value of the current is proportional to the square on the basis of the power consumption, the deviation of the current consumption value of the conventional clothes treating apparatus is larger as shown in FIG.

Therefore, the experimental data demonstrates that the laundry treatment apparatus of the present invention consumes almost uniform power even when the washing course and options are repeated a plurality of times, or the consumption thereof is smaller than before.

Fig. 9B shows the ratio of the maximum vibration value of the first rinsing dehydration step and the maximum vibration value of the second rinsing dehydration step of the conventional clothing processing apparatus and the clothes treating apparatus of the present invention. (Maximum vibration of 2 rinsing dehydration stage / maximum vibration of 1st rinsing dehydration stage)

In the conventional clothing treatment apparatus, excessive vibration occurs every time the drum is rotated due to the twisting or agglomeration of the clothes in the rinsing step. However, the laundry treatment apparatus of the present invention almost generates vibration even when the clothing is always attached to the inner wall of the drum even when the rinsing step is performed. It can be seen that it is uniform. Therefore, the experimental data proves that the laundry treatment apparatus of the present invention has a smaller vibration generation amount. (This is because the first rinsing dehydration is performed through the unbalance detection step, so the vibration amount is small.)

The present invention may be practiced in various forms and is not limited to the above-described embodiment. Therefore, if the modified embodiment includes the components of the claims of the present invention will be considered to belong to the scope of the present invention.
