Description

Controlling Method of Washing Machine

The present invention relates to a control method of a laundry machine, and more particularly, to a method of controlling a laundry machine, which is easy to use and can satisfy various consumer demands, by effectively washing laundry that may be damaged.

In general, a washing machine is a device for removing dirt from laundry by the action of water and detergent.

The washing machine is largely divided into stirring, vortex and drum washing machines.

The stirring type washes by rotating the laundry rod rising to the left and right in the center of the washing tank, and the vortex type washes by using the friction force between the water flow and the laundry by rotating the disc-shaped rotary blade formed at the lower part of the washing tank to the left and right, and the drum type inside the drum. Add water, detergent and laundry to wash the drum by rotating it.

The drum washing machine is equipped with a tub in which washing water is accommodated in a cabinet forming an exterior, a drum in which laundry is accommodated, and a back of the tub is provided with a motor and a shaft for rotating the drum. .

The drum type laundry machine having the above-described configuration removes dirt contained in the laundry by the frictional force of the wash water stored in the tub and the laundry stored in the drum, and the chemical action of the detergent stored in the wash water.

Therefore, the combination of the rotational direction and the rotational speed of the drum is closely related to the washing performance of the washing machine.

On the other hand, since the drum is powered from the motor provided on the back of the tub, the combination of the rotational direction and the rotational speed of the drum designed to improve the washing performance of the washing apparatus must be considered the load on the motor.

In the case of a drum washing machine, washing is performed while the laundry inside the drum flows as the drum rotates. In general, laundry damage in a drum washing machine is known to be less than agitation or vortex type.

In the case of a conventional drum washing machine, laundry and rinsing were performed by a tumble drive in which laundry inside a drum was lifted and dropped. Therefore, damage of laundry of cotton or the like is not a big problem, but damage of laundry of delicate materials such as wool or synthetic fibers could not be overlooked. Of course, the conventional drum washing machine attempted to prevent the damage of the laundry of the delicate material by driving the drum by varying the actual operation rate (on time of the drum / off time of the drum) according to the material of the laundry.

For example, when washing laundry made of cotton, the driving time of the drum is longer than the stopping time, and when washing laundry made of delicate fibers such as wool or silk, the driving time of the drum is shorter than that of the cotton material. It was.

However, despite these attempts, the laundry is likely to be damaged due to the tumble drive. When the operation rate is too low, the washing efficiency is significantly lowered.

Therefore, there is a need for a laundry apparatus and a control method thereof capable of preventing damage to laundry and increasing washing efficiency.

On the other hand, in recent years there are a lot of people enjoying leisure demand for sportswear is increasing. Such sportswear is made of special materials, and there is an increasing demand for easy washing of such sportswear at home.

For example, sportswear is made of various materials such as Coolmax and Tactel. Such a material is a material that accelerates sweat absorption and improves ventilation. In addition, it has excellent quick-drying action, which lowers body temperature in summer and keeps dry in winter, so it is widely used in sportswear. Accordingly, there is a need for a washing apparatus and a control method thereof capable of optimally reflecting the properties of such materials.

An object of the present invention is to provide a method of controlling a washing apparatus that can prevent washing damage and improve washing efficiency.

More specifically, an object of the present invention is to provide a washing apparatus and a control method thereof, by which a user can easily select a washing course capable of performing optimal washing according to a material of laundry.

In addition, an object of the present invention is to provide a control method of a laundry machine that is convenient to use by shortening the washing time by controlling the motion of the laundry flowing in the drum according to the course selected according to the material of the laundry.

It is an object of the present invention to provide a washing apparatus and a control method thereof which can increase the efficiency of the user's satisfaction by increasing the efficiency of the washing course as a whole through the optimum efficiency and the time required for each stage of the washing administration. .

An object of the present invention is to provide a washing apparatus and a control method thereof which can easily wash wool, delicate fibers and sportswear.

In order to solve the above technical problem, the present invention comprises the steps of selecting a course to be driven from a plurality of driving courses from the user; Washing operation step of washing the laundry is performed in a swing motion in which the laundry flows to the left and right to rotate the drum after the rotation of the predetermined angle in the forward direction and then rotate the power generation after the predetermined angle in the reverse direction; Rinse administration step of rinsing; And a dehydration administration step in which dehydration is performed.

The selected driving course is preferably a driving course provided for washing wool or fine fiber laundry or sportswear. Therefore, when such a course is selected, it is desirable to wash the laundry in swing motion.

Swing motion is a motion in which the rotation of the drum is smoothly converted, so that the laundry substantially flows smoothly at the bottom of the drum. Then, it can be seen as a motion of washing laundry gently by washing the laundry. Through this motion, the hand washing effect can be realized in the drum washing apparatus. In addition, it is possible to increase the wash water level so that most of the laundry is immersed in the wash water. Through this, it can be expected to wash the laundry in the soaked laundry and washing water while washing.

On the other hand, there is a fear that the laundry of wool material shrinks in response to a change in temperature or a change in applied mechanical force. Therefore, when the driving course is selected to wash the laundry of the wool material, the swing motion is preferably carried out until the end of the laundry administration. That is, the drum drive is not stopped after repeated swing motion, it is preferable to continue to drive the drum until the end of the washing stroke.

Here, the drum drive of the swing motion is a drive that does not lift the laundry substantially to the top of the drum. The load on the motor during drum rotation is greatest near the left and right 90 ° angles of the drum. Therefore, in the swing motion, the drum does not rotate to the maximum range of the load on the motor, and since the rotation is performed in both directions, the load on the motor can be minimized.

In addition, swing motion does not perform reverse phase braking for braking of the motor. In other words, gentle braking is achieved, so that the load on the motor due to braking is less.

In consideration of the characteristics of the swing motion and the characteristics of the wool material it is desirable to repeat the swing motion until the end of the washing administration.

When the driving course is selected to wash the laundry of wool material, it is preferable that the rinse administration step is repeated three times from water supply to rinsing after draining. This is to prevent the residual detergent from being rinsed sufficiently.

Unlike a general rinsing stroke, when selecting a driving course (wool course) provided to wash laundry of wool material, it is preferable that the drainage before the water supply after drainage is not performed. In other words, it is preferable that gantal may be performed but not gallant. Centrifugal force is generated due to the high RPM of the RPM drive to pull the laundry of the wool material, which is to prevent the problem that the laundry is deformed in advance. Then, the drum is driven in a swing motion in the rinsing stroke step.

When selecting a driving course (delicate course) or a sportswear course which is designed to wash laundry made of delicate fibers, the washing administration preferably includes a sieve step in which a sieve is performed by a combination of swing motion and filtration motion. .

The driving course prepared for washing such delicate fibers is a course prepared for washing very thin and delicate fibers such as thin film cloth, lace, and spinning. In addition, the course is designed to wash plastic fibers such as shower curtains, and textiles with metal ornaments and accessories. In addition, this course is designed to wash garments sensitive to cloth damage, such as women's underwear or blouses with very delicate cotton or silk.

Here, the step of dissolving the detergent through the swing motion is performed in the step of washing the water from the outside during the wool course and the delicate course. Specialty cleaners such as neutral detergents are suitable for wool and delicate courses. And these special detergents are usually liquid detergents. Therefore, detergent dissolution can be quickly achieved by weak water flow, not by strong water flow.

In the case of selecting a sportswear course, the step of dissolving the detergent through scrub motion for a short time is preferably performed.

On the other hand, fine fibers and sportswear may have a low water content due to the nature of the material. Therefore, there is a fear that a sufficient amount of washing water cannot be supplied to the laundry. To prevent this, a cladding step may be performed. Similarly, the swinging motion may be performed in the core coating step, and the filtration motion is preferably performed. The RPM in the filtration motion is not for discharging the wash water from the laundry by centrifugal force, but for supplying the wash water sufficiently by increasing the surface area of the laundry. Therefore, it is desirable to rotate the drum at about 100 RPM to prevent damage to the laundry.

When the delicate course is selected, it is preferable that the main washing step of washing is performed by a combination of swing motion and tumbling motion in the washing stroke after water supply is completed. In addition, the rinsing stroke may be repeated twice from water supply to rinsing after draining, and tumbling motion is preferably performed in the rinsing stroke. Here, it is preferable that the actuation rate in tumbling motion is very low.

When the sportswear course is selected, it is preferable that the main washing step of washing is performed in the swing motion in the washing stroke after water supply is completed.

On the other hand, when the wool course or the delicate course is selected, it is preferable that the washing cycle and the rinsing stroke in the washing cycle circulated to supply the laundry in the drum. In addition, the drum RPM in the swing motion is preferably the RPM that the laundry is not lifted more than 90 degrees left and right.

And, in order to prevent damage to the laundry by the water temperature, the temperature of the wash water is preferably controlled not to exceed 40 degrees Celsius. In particular, the water temperature in the wool course is set to 40 degrees, and in the delicate course is preferably set to 30 degrees.

When the sportswear course is selected, the drum may be driven in a scrub motion during the initial water supply of the washing administration stage. That is, the drum may be driven in a scrub motion in the detergent dissolution promoting step. Afterwards, the loading step may be performed in a rolling motion. It is preferable that the drum is driven in the filtration motion while the circulation step is performed in order to further enhance the foaming effect. The combination core step may be performed by the combination of the filtration motion and the rolling motion.

According to the present invention, it is possible to provide a washing apparatus capable of preventing damage to laundry and improving washing efficiency.

More specifically, it is possible to provide a washing apparatus and a control method thereof in which a user can easily select a washing course capable of performing optimal washing according to the material of laundry.

In addition, by controlling the motion of the laundry flows in the drum according to the course selected according to the material of the laundry to reduce the washing time can provide a convenient washing apparatus and a control method thereof.

It is possible to provide a washing apparatus and a control method thereof, which can prevent damage to laundry of wool or delicate fiber material and effectively wash the laundry.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Unless otherwise defined, all terms in the specification are the same as the general meaning of the terms understood by those skilled in the art, and if the terms used herein conflict with the general meaning of the terms Is in accordance with the definitions used herein.

On the other hand, the configuration or control method of the device to be described below is not intended to limit the scope of the present invention, but to describe the embodiment of the present invention, the same reference numerals are used throughout the specification the same components Indicates.

1 is a perspective view of a washing machine that is the control object of the washing machine of the present invention.

The washing apparatus includes a cabinet 110 forming an exterior, a tub 120 provided inside the cabinet and supported by the cabinet, a drum 130 rotatably provided inside the tub, and laundry loaded therein. And a motor 140 for rotating the drum by applying torque to the drum, and a control panel 115 for allowing a user to select and execute a washing course.

The cabinet 110 includes a main body 111, a cover 112 provided on the front surface of the main body and coupled to each other, and a top plate 116 coupled to the upper portion of the main body. The cover 112 may include an opening 114 provided to allow access to and from the laundry, and a door 113 to selectively open and close the opening.

The drum 130 forms a space for washing laundry put into the drum 130. The drum 130 is rotated by receiving power from the motor 140. Since the drum 130 includes a plurality of through holes 131, the wash water stored in the tub 120 may be introduced into the drum 130 through the through holes 131, and the washing inside the drum may be performed. Water can flow out of the tub. Therefore, when the drum is rotated, the laundry put into the drum is removed from the dirt during the friction with the wash water stored in the tub.

The control panel 115 is not only a user can input the information related to the washing, but also configured to check the information related to the washing. That is, the configuration for the interface with the user.

Accordingly, the control panel 115 includes manipulation units 117 and 118 through which a user can input a control command, and a display unit 119 displaying control information according to the control command. And the control panel may include a control unit for controlling the driving of the washing machine including the operation of the motor in accordance with the control command.

According to the control method of the washing apparatus of the present invention, the drum can be driven in various forms. That is, drum driving is performed in various forms as well as general tumble driving and spin driving. The tumble drive is a drum drive motion that drops after the laundry is lifted during washing or rinsing of a general drum washing machine, and the spin drive is a drum drive motion in which laundry is continuously rotated while the laundry is stuck inside the drum.

Drum drive motion in the present invention refers to the motion of the laundry flow in the drum associated with this as well as the RPM of the drum rotation. Accordingly, the present invention provides a control method of a motor for generating drum rotation, in particular, rotation of the drum for driving the drum in various drum driving motions.

Hereinafter, various drum driving motions applicable to embodiments of the present invention will be described in detail.

Figure 2 is a view showing a variety of drum driving motion utilized in the control method of the present invention laundry machine.

Drum driving motion means a combination of the rotational direction and the rotational speed of the drum, the laundry located inside the drum by the drum driving motion is different in the falling direction, the dropping time and therefore the flow of the laundry in the drum is different You lose. The drum driving motion is implemented by controlling the motor.

Since the laundry is raised by the lift 135 provided on the drum inner circumferential surface when the drum is rotated, the impact applied to the laundry can be changed by controlling the rotation speed and the rotation direction of the drum. That is, the mechanical forces such as friction between laundry, friction between laundry and washing water, and dropping impact of laundry can be changed. In other words, it is possible to vary the degree of tapping or rubbing the laundry for washing, it is possible to vary the degree of dispersion or flipping of the laundry.

Accordingly, the present invention provides a method for controlling a washing machine having various drum driving motions, and thus, the drum driving motion is optimized according to the detailed steps of the type of laundry, the degree of contamination of the laundry, each step, and each step. It is possible to process the laundry by the mechanical power of. This can improve the washing efficiency of the laundry. In addition, due to the consistent drum drive motion it can prevent excessive washing time to reduce the time required.

On the other hand, in order to implement such various drum driving motion, the motor 140 is preferably a direct type motor. That is, the stator of the motor is preferably the tub 120 is fixed to the rear, the rotor of the motor is rotated to drive the drum 120 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).

On the other hand, in the form of transmitting the rotational force of the motor to the rotating shaft through the pulley, the drum driving motion of the form that allows time delay or backlash, for example, tumbling drive or spin drive will be possible. Therefore, it is not desirable to implement various drum driving motions. The type of driving method of the motor and the drum is obvious to those skilled in the art, so detailed description thereof will be omitted.

2 (a) is a diagram showing a rolling motion (rolling motion). The rolling motion is a motion in which the motor 140 rotates the drum 140 in one direction, and the laundry on the inner circumferential surface of the drum falls to the lowest point of the drum at a position less than about 90 degrees in the drum's rotation direction.

That is, when the motor 140 rotates the drum at about 40 RPM, the laundry located at the lowest point of the drum 140 rises a predetermined height along the rotational direction of the drum 140 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 laundry continues to roll in three quadrants of the drum.

The laundry is washed through the rolling motion through friction with the wash water, friction between the laundry, and friction with the drum inner circumferential surface. And through this motion, the laundry is turned upside down enough to obtain the effect of gently scrubbing the laundry.

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 laundry in the drum. Due to the difference in size between the centrifugal force and gravity, the flow of laundry in the drum is changed. Of course, the rotational force of the drum and the friction between the drum and the laundry should also be considered.

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

FIG. 2B is a diagram showing tumbling motion.

The tumbling motion is a motion in which the motor 140 rotates the drum 130 in one direction, but the laundry on the inner circumferential surface of the drum falls 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 during washing and rinsing because mechanical force is generated only by controlling the drum to rotate in one direction at an appropriate RPM.

That is, the laundry put into the drum 140 is located at the lowest point of the drum 130 before the motor 140 is driven. When the motor 140 provides torque to the drum 130, the drum 130 rotates, and the lift 135 provided on the inner circumferential surface of the drum moves laundry from the lowest point in the drum to a predetermined height. . If the motor 140 rotates the drum 140 to about 46 RPM, the laundry drops from the lowest point of the drum to the lowest point of the drum at a position of about 90 to 110 degrees in the rotational direction.

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 drum's inner peripheral surface to the lowest point of the drum.

Therefore, the tumbling motion allows the laundry to be washed by the impact force caused by friction and dropping with the wash water, thereby performing washing and rinsing with a mechanical force greater than that of the rolling motion. And, because the motion to fall off the drum to some extent it is effective to separate the tangled laundry and to disperse the laundry.

2 (c) is a diagram showing step motion. The step motion is a motion in which the motor 140 rotates the drum 130 in one direction, but the laundry on the inner circumferential surface of the drum drops 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 motor 140 rotates the drum 130 to about 60 RPM or more, the laundry can be rotated without falling by centrifugal force. The step motion is performed at a speed such that the laundry does not fall from the drum inner circumferential surface by the centrifugal force. After the drum is rotated, the drum is braked to maximize the impact force on the laundry.

In the step motion, the motor 140 rotates the drum at a speed at which the laundry does not fall from the outer circumferential surface of the drum by centrifugal force (about 60 RPM or more), and the laundry is located near the highest point of the drum (180 degrees in the rotational direction). The reverse torque is controlled to supply the drum 130.

Therefore, the laundry rises in the rotational direction of the drum at the lowest point of the drum 130 and then falls from the highest point of the drum 130 to the lowest point at the moment the drum is stopped by the reverse torque of the motor 140. Is a motion of washing by the impact force caused by the process of the laundry in the drum falls to the maximum drop. 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 more effectively provide a mechanical force when the amount of small amount.

On the other hand, the motor 140 is preferably reversed braking for braking the drum. The reversed phase 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 rapid braking of the motor. Accordingly, the reversed braking is the most suitable braking method for the step motion which gives a strong impact on the laundry.

Thereafter, the motor 140 applies torque to the drum 130 again to raise the laundry 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 step motion is implemented by applying the torque to rotate clockwise again.

As a result, the step motion is a motion of washing the laundry and the laundry introduced into the through-hole 131 during the rotation of the drum, and washing the laundry by the impact force when the laundry is located at the top of the drum.

Figure 2 (d) is a view showing a swing motion (swing motion). The swing motion is a motion in which the motor 140 rotates the drum 130 in both directions, so that laundry is dropped at a position less than about 90 degrees in the rotation direction of the drum.

That is, when the motor 140 rotates the drum 130 counterclockwise to about 40 RPM, the laundry located at the lowest point of the drum 130 rises a predetermined height counterclockwise. At this time, the motor stops the rotation of the drum before the laundry reaches a position of about 90 degrees counterclockwise of the drum so that the laundry moves to the lowest point of the drum at a position less than about 90 degrees counterclockwise of the drum.

Thereafter, the motor 140 rotates the drum 130 clockwise to about 40 RPM so that the falling laundry rises a predetermined height clockwise along the rotational direction of the drum. On the other hand, the motor 140 stops the rotation of the drum before the laundry reaches the position of the drum clockwise of about 90 degrees so that the laundry drops to the lowest point of the drum at a position less than about 90 degrees clockwise 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 laundry rises from the three quadrants of the drum to a portion of the second quadrant and then falls gently. It can be said to be a form that repeatedly rises up and falls smoothly.

At this time, the braking of the motor 140 can minimize the load generated on the motor 140 by using the power generation braking, minimize the mechanical wear of the motor 140, and at the same time can control the impact applied to the laundry.

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 motor 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, unlike the reverse braking, does not brake the motor smoothly but smoothly changes the rotational direction of the drum.

Thus, visually, the swing motion is a form in which the laundry flows in the form of eight characters lying sideways over the third and fourth quadrants of the drum.

Figure 2 (e) is a view showing a scrub motion (scrub motion). The scrub motion is a motion in which the motor 140 rotates the drum 130 in both directions, and the laundry is dropped at a position of about 90 degrees or more in the rotation direction of the drum.

That is, when the motor 140 rotates the drum 130 counterclockwise to about 60 RPM or more, the laundry located at the lowest point of the drum 130 rises a predetermined height counterclockwise. At this time, the motor is to stop the rotation of the drum by providing a reverse torque to the drum after the laundry has passed the counterclockwise position of about 90 degrees. Then, the laundry on the inner circumferential surface of the drum drops rapidly.

Thereafter, the motor 140 rotates the drum clockwise at about 60 RPM to raise the dropped laundry a predetermined height clockwise. The motor 140 stops rotation of the drum by providing reverse torque to the drum 130 when the laundry passes through the clockwise 90 degree position of the drum. Therefore, the laundry on the inner circumferential surface of the drum falls to the lowest point of the drum at a position 90 degrees or more clockwise of the drum.

Therefore, the scrub motion is to wash the laundry by dropping the laundry sharply at a predetermined height. On the other hand, the motor 140 is preferably reversed braking for braking the drum.

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

Figure 2 (f) is a view showing the filtration motion (filtration motion). The filtration motion is a motion in which the motor 140 rotates the drum 130 so that the laundry does not fall from 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 laundry is unfolded, so that the washing water is sprayed into the drum while the washing water is rotated by the centrifugal force to the tub 120 through the laundry, the through hole 131 of the drum. Get out. Therefore, the filtration motion expands the surface area of the laundry while allowing the washing water to penetrate the laundry, thereby obtaining the effect of supplying the washing water evenly to the laundry.

2 (g) is a diagram showing a squeeze motion. The squeeze motion repeats the operation of separating the laundry from the inner peripheral surface of the drum by lowering the rotational speed of the drum 130 after rotating the drum 130 so that the laundry does not fall from the inner peripheral surface of the drum by centrifugal force The motion of spraying the washing water into the drum during the rotation of the drum.

In other words, the filtration motion is continuously rotated at a speed at which the laundry does not fall from the inner circumferential surface of the drum, but the squeeze motion changes the rotation speed of the drum to repeat the washing and close contact with the inner circumferential surface of the drum 130. There is.

The process of spraying the washing water into the drum 130 during the filtration motion and the squeeze motion may be implemented as a circulation passage and a pump although not shown in FIG. 1. The pump communicates with the bottom of the tub 120 to pressurize the washing water, and the circulation passage may be provided so that one side is connected to the pump and the other side may spray the washing water from the top of the drum into the drum. .

However, since the above-described circulation flow path and the pump are necessary to inject the laundry water stored in the tub, it is not necessary to exclude the case of spraying the washing water into the drum through the injection water supply flow path connected to the water supply source outside the cabinet. no.

That is, if the injection water supply passage has one side connected to the water supply source, the other side is connected to the tub, but provided with a nozzle for injecting the washing water into the drum, washing water into the drum of the filtration and squeeze motion Will be able to spray.

3 shows the step motion in more detail. When the motor 140 applies torque to the drum 130 in a predetermined direction, the drum rotates in a predetermined direction, so that the laundry is brought into close contact with the inner circumferential surface of the drum 130. At this time, the drum is preferably rotated to about 60 RPM or more so that the laundry can rise in close contact with the inner peripheral surface of the drum. Here, the rotational speed of the drum is determined in relation to the inner diameter of the drum, and is determined as the rotational speed at which the centrifugal force becomes larger than gravity.

Immediately before the laundry reaches the highest point in the drum past the point of rotation of the drum 130 in the 90 degree direction, the motor 140 is braked in reverse to temporarily stop the rotation of the drum. Since the inverse braking timing of the motor 140 is closely related to the position of the laundry in the drum 130, a device capable of determining or predicting the position of the laundry is preferably provided, and a hole capable of determining the rotation angle of the rotor. An example is a sensing device having a Hall effect sensor.

Through the Hall sensor, the controller may determine the rotation direction as well as the rotation angle of the rotor. Details thereof will be apparent to those skilled in the art, and thus a detailed description thereof will be omitted.

The control unit may determine the rotation angle of the drum through the sensing device, and controls the motor 140 to reverse brake before the drum reaches 180 degrees. In this case, the reverse phase braking means applying a reverse phase current so that the drum rotates in the opposite direction. For example, after the current is applied to the motor to rotate clockwise, the current is suddenly applied to rotate counterclockwise.

Therefore, the drum rotated in the clockwise direction stops at an instant, and the angle is substantially 180 degrees so that the laundry drops from the highest point in the drum to the lowest point in the drum. Thereafter, current is continuously applied so that the drum continues to rotate clockwise.

3 illustrates a case in which the drum rotates clockwise, step motion may be performed during counterclockwise rotation. However, since the step motion generates a high load on the motor 140, it is preferable to lower the running rate.

The running rate is the ratio of the driving time of the motor to the sum of the driving time and the stopping time of the motor 140, and the running rate 1 means that the motor is driven without the stopping time. In the case of the step motion, it is preferable that the control rate is about 70% when considering the load of the motor. For example, the step motion may be stopped for 4 seconds after driving for 10 seconds.

4 is a view showing scrub motion in more detail. When the motor 140 applies torque to the drum 130, the laundry in the drum rotates clockwise. The drum 130 preferably controls the motor 140 to have a rotation speed of about 60 RPM or more so that laundry can rotate in close contact with the inner circumferential surface of the drum. Then, when the laundry passes through the 90 degree point in the rotational direction of the drum, the motor 140 is braked in reverse, so that the laundry closely attached to the inner circumferential surface of the drum falls to the lowest point of the drum.

When the laundry falls to the lowest point, the motor 140 provides torque for rotating the drum counterclockwise. Therefore, the dropped laundry adheres to the inner circumferential surface of the drum and rotates in a counterclockwise direction. When the laundry is located between a 90 degree counterclockwise point and the highest point of the drum at the lowest point of the drum, the motor is braked in reverse and thus close to the inner circumferential surface of the drum. The laundry will fall to the lowest point of the drum.

As described above, the scrub motion generates a high load on the motor 140 as in the step motion, and thus is preferably executed by lowering the running rate. The scrub motion is stopped at 4% after performing the scrub motion for 10 seconds to 70% running rate. One example is controlled.

On the other hand, although not shown in the swing motion is changed the braking method of the motor in the scrub motion to the power generation braking, and since the time of power generation braking is changed to when the laundry reaches the 90 degrees of the rotational direction of the drum, detailed description thereof will be omitted.

FIG. 5 is a graph comparing the cleaning force and the degree of vibration of each motion disclosed in FIG. 2. The horizontal axis represents the washing force, and the more the left side is, the easier it is to separate the dirt contained in the laundry. The vertical axis represents the vibration or noise level, and the vibration level increases as the upper direction increases, but the washing time for the same laundry decreases.

The step motion and scrub motion is a motion suitable for the washing course to reduce the washing time and the case of heavy contamination of the laundry due to the excellent washing power. In addition, the step motion and scrub motion is a motion with a high level of vibration and noise. Therefore, when the laundry is sensitive clothing or the washing course that needs to minimize noise and vibration is an undesirable motion.

The rolling motion is a motion characterized by excellent washing power and low vibration level, minimizing laundry damage and low motor load. Therefore, it can be applied to all washing courses, but it is a motion suitable for the initial washing detergent dissolution and washing wet.

The tumbling motion has a lower washing force than the scrub motion but the vibration level is a motion between the scrub motion and the rolling motion. Since the rolling motion takes longer washing time than the tumbling motion instead of low vibration level, the tumbling motion is applicable to all washing courses but is a useful motion especially for the step for podis dispersion.

The squeeze motion is similar to the tumbling motion in terms of the fine force, and the vibration level is higher than the tumbling motion. The squeeze motion is a useful motion for the step of rinsing because the washing water is discharged to the outside of the drum in the process of repeating the contact and separation of the laundry on the inner peripheral surface of the drum.

The filtration motion has a lower cleaning force than the squeeze motion, and the noise level is similar to that of the rolling motion. The filtration motion is a motion that is useful for the step where the washing water is discharged to the outside of the drum through the laundry in a state in which the laundry is in close contact with the inner peripheral surface of the drum.

The swing motion is the motion with the lowest vibration level and washing power. Therefore, swing motion is a motion that is useful for low noise or low vibration washing courses and is suitable for washing sensitive clothes.

As mentioned above, each drum drive motion has advantages and disadvantages. Therefore, it would be desirable to use these various drum driving motions appropriately. And each drum drive motion will have advantages and disadvantages in relation to the quantity. Therefore, in the same course, the same stroke, etc., it would be desirable to use various drum driving motions properly in relation to the quantity of the gun.

Hereinafter, a control method of a washing apparatus according to an embodiment of the present invention will be described in detail with reference to FIG. 6.

This embodiment relates to a control method for performing a washing course. The washing course here refers to the operation of a washing machine in which washing strokes, rinsing strokes and dehydration strokes are automatically performed in sequence. The washing course may be selected through the course selection unit 117.

The course selector 117 may generally be provided in the form of a rotary knob. A plurality of courses are printed around the rotary knob, and the user may select a specific course among the plurality of courses by rotating the rotary knob. The rotary knob is provided with LEDs corresponding to the respective courses, and when a specific course is selected, the corresponding LED is emitted so that the user can easily know which course is selected.

Since the matter about the course selection unit 117 will be apparent to those skilled in the art, detailed description thereof will be omitted.

The user selects a desired driving course through the course selection unit 117 provided in the control panel 115. That is, the controller receives a course to be driven among the plurality of driving courses from the user (S10). The input driving course is a washing course for washing the laundry using the wash water and detergent, a rinsing stroke for discharging residual detergent and contaminants from the laundry using the wash water, and a dehydration stroke for discharging the washing water from the laundry. It is made, including.

On the other hand, it is preferable that the driving course is provided in a variety of ways. There are a plurality of such driving courses depending on the type of laundry, the material, and the specific purpose.

According to an embodiment of the present invention, a step of receiving a selection of a course to be driven among a plurality of driving courses by a user is performed, and a washing administration step is performed according to the selected driving course.

Here, the selected driving course is preferably a wool course, a delicate course or a sportswear course. That is, it is preferable that the course is suitable for laundry having relatively little contamination and fear of damage.

When the course is selected, the drum is rotated by a predetermined angle in the forward direction, and the power generation brake is repeated after the predetermined angle is rotated in the reverse direction, and the washing administration step in which the washing is performed in a swing motion in which the laundry flows from side to bottom in the drum ( S100) is preferably performed. At this time, the washing water level is preferably a high water level in which the water level inside the drum can be confirmed from the outside. Therefore, the swing motion is made while a large part of the laundry is immersed in the wash water.

Here, it is preferable that the washing level is a level above the level where the lift 135 is completely locked. Therefore, the frictional force between the drum inner peripheral surface and the laundry is minimized, and the operation of touching the laundry while rotating the laundry immersed in the wash water can be repeated. This prevents damage to the laundry and allows for gentle washing or rinsing.

As described above, the swing motion may be referred to as a motion of washing laundry in a wash water by gently shaking the laundry in a drum. This motion minimizes damage to the laundry and increases the time that the wash water and detergent come in contact with the wash water, thereby increasing the washing effect.

When the washing administration step (S100) is finished, the rinsing administration step (S200) and the dehydration administration step (S300) is performed in order to end all selected driving courses.

The wool course is designed for washing hand washable wool. The delicate course is designed to wash delicate fibers such as silk or plastic fibers, or clothing with metal ornaments or accessories. In addition, the sportswear course is provided for washing laundry of a functional material having excellent sweat absorption performance and breathability, such as mountain climbing clothes and sportswear.

Laundry made of these materials is highly susceptible to damage when washing with strong mechanical force. Therefore, it is preferable to wash gently through the swing motion as described above.

On the other hand, in consideration of the characteristics of the material, the drum driving in the specific washing stroke step (S100), rinsing stroke step (S200) and dehydration stroke step (S300) is preferably controlled differently.

First, the control method when the wool course is selected will be described in detail.

In the initial washing administration step (S100), washing water and detergent are supplied to the tub or drum. That is, the water supply step S110 is performed. The water supply step (S110) may be a detergent dissolution promotion step (S111) to facilitate the initial detergent dissolution of the water supply step and a weaving step (S112) of sufficiently washing the laundry to prepare the main washing step after the water supply is performed. Here, the coating core step S112 may be performed after all of the water supply is finished, or may be performed before the water supply is finished.

Here, the detergent used in the wool course is preferably a neutral detergent, such a neutral detergent is generally a liquid detergent. Therefore, it does not take much time to dissolve the detergent in the wash water compared to the powder detergent.

In view of these matters, it is more preferable to supply washing water together with the wash water at the beginning of the water supply. When water is started, the washing water is supplied to the liquid detergent provided in the detergent container, and the washing water and the liquid detergent are mixed and supplied to the tub or drum. Therefore, in order to supply the washing water and the liquid detergent to the laundry more quickly, the washing water and the liquid detergent supplied are more preferably mixed and sprayed into the laundry inside the drum.

And, it is preferable that a circulation step of supplying the washing water in the tub from the upper drum for more effective detergent dissolution is performed.

At this time, the drum drive is preferably swing motion. Soft vortices are generated in the wash water to promote detergent dissolution and to prevent damage to the laundry.

When the water supply is finished, the circulation step may be performed together with the swing motion to prepare the main washing step. This step can be seen as a sieve step (S112).

On the other hand, when the above-described detergent dissolution promoting step (S111) and the bubbling step (S112) is finished, a heating step (S120) for heating the wash water as needed. However, the washing water temperature in the heating step is preferably controlled not to exceed 40 degrees Celsius. This is because when the temperature of the wash water is higher, the laundry of the wool material may be deformed and damaged by heat. The temperature of 40 degrees Celsius is a temperature that promotes the activation of the detergent and the degree of washing water is absorbed into the laundry without heat deformation.

The drum drive in the main washing step (S130) is preferably a swing motion. The main washing step is a step in which the most time is spent in the washing administration step (S100) substantially, and washing is performed in earnest. Therefore, it is necessary to prevent damage to the laundry in the main washing step. Swing motion is preferred for this.

On the other hand, it is not desirable to repeat the stopping and applying the mechanical force to the wool laundry. That is, there is a concern that shrinkage of laundry may occur through such repetition. In order to prevent this, it is preferable that the swing motion is continuously performed in the main washing step (S130).

As described above, since the swing motion is to drive the drum through power generation braking, the load on the motor is not large. In addition, it can be said to be a drum drive reciprocating between the angle of less than 90 degrees left and right. Therefore, there is no heavy load to lift the laundry. If the drum is continuously driven through a scrub motion, step motion, or the like, a large burden may be generated on the motor. In addition, the tumbling motion may be less burden on the motor than the scrub motion and step motion, but there is a risk of damage to the laundry because the drum drive to lift and drop the laundry. Reflecting this, it is most preferable that the swing motion is continuously performed in the main washing step.

When the washing administration step (S100) is finished, the rinsing administration step (S200) is performed.

In general, when the washing administration step is completed, the intermediate dehydration is performed after draining. The wash water is then watered to begin rinsing after intermediate dewatering. In addition, the rinsing administration step may be rinsed a plurality of times as necessary. That is, drainage may be repeated several times after watering and rinsing. In general, intermediate dehydration is also performed between the water supply after drainage.

In this case, the intermediate dehydration may include enthaling for performing a defogging at a low spin rotation and intermittent for detecting vibration and a dehydration for a predetermined time at a high spin rotation. Ganta may be performed at approximately 100RPM, main bone may be performed at about 200RPM (low speed resonant frequency) or more.

However, if a wool course is chosen, this intermediate dewatering process is preferably omitted. Medium dewatering is the process of draining the wash water from the laundry by centrifugal force. Through this process, tension is inevitably generated in the laundry. Therefore, there is a fear that the laundry is damaged through the intermediate dehydration process due to the nature of the wool material vulnerable to external forces. In order to alleviate this concern, it is desirable to omit the intermediate dehydration process.

More specifically, in the middle dehydration, the main stripping may be omitted, and only the liver stripping may be performed. This is because the rinsing performance may be significantly reduced when all processes of discharging the washing water by centrifugal force are omitted. In consideration of rinsing performance and damage to laundry, only deboning can be omitted in intermediate dewatering and only deboning can be performed.

On the other hand, the series of rinses leading to the drainage after the water supply is preferably controlled to be performed three times. This is to ensure that the residual detergent is sufficiently discharged from the laundry. Here, the water level during the rinsing is preferably controlled higher than the water level in the washing step. In addition, it is preferable that the circulation step is performed at the time of rinsing.

In general, in the case of using a liquid detergent, it is possible to discharge the residual detergent sufficiently by two rinsing cycles through an intermediate dehydration process. However, in the case of this course, since the intermediate dehydration process is omitted in order to prevent damage to the laundry, it is preferable to perform three rinsing processes for a sufficient rinsing effect.

The drum drive during rinsing is preferably a swing motion. That is, to prevent damage to the laundry. The swing motion gently shakes the laundry in the wash water so that the residual detergent absorbed in the laundry is discharged into the wash water, thereby increasing the rinsing efficiency.

When the rinsing administration step (S200) is finished, the spin-driving drum is dewatering administration step (S300) for discharging the wash water from the laundry. The drum RPM here is preferably preset not to exceed 800 RPM for the protection of laundry.

Hereinafter, the control method when the delicate course is selected will be described in detail.

Initial detergent dissolution promoting step (S111) may be performed in the same manner as the wool course described above. This is because detergents for washing delicate garments are generally prepared as liquid detergents.

However, after the detergent dissolution promoting step (S111) is finished, it is preferable that the coating step (S112) is performed differently from the above-described wool course. Wool is better at absorbing wash water than fine fibers. In addition, delicate fibers are sometimes more susceptible to heat than wool. For this reason, the temperature of the washing water for washing the delicate fibers is preferably set to 30 degrees Celsius. Of course, cold water may also be selectable, but it is preferable not to select a temperature exceeding 40 degrees.

Due to these material properties, it is desirable to carry out the bubbling effectively. To this end, the coating core step (S112) may be a filtration motion. Spin driving the drum to distribute the laundry evenly inside the drum to increase the surface area, it is preferable that the circulation step of circulating the washing water in the tub to supply the laundry. In addition, by submerging the laundry in the wash water in the swing motion to generate a smooth flow it can promote the siege. It is desirable to promote the seam in various forms by repeating the filtration motion and swing motion.

On the other hand, the drum drive motion in the core step (S112) may be performed only as a swing motion.

When the packing is finished, the main washing step (S130) is performed. Likewise, the drum drive in the main washing step is preferably swing motion.

Delicate fibers, on the other hand, are more resistant to external forces than wool. Therefore, in order to obtain a more effective washing efficiency, the drum driving in the main washing step (S130) may be performed by combining a swing motion and a tumbling motion. Here, the washing water level is preferably a high water level. Of course, it can also be performed with only tumbling motion.

Thus, the falling laundry will hit the wash surface instead of the drum bottom. In other words, the falling distance is reduced by that amount. Therefore, the washing water level is high, thereby reducing the impact on the laundry while generating vortices in the washing water, thereby increasing the washing effect. In addition, since the laundry is low in contamination, the time required for the main washing step S130 may be relatively short. And, the actual operation rate can also be preset relatively low. Therefore, there is less concern about laundry damage even if tumbling motion is performed.

In addition, in the main washing step (S130), the circulation step may be performed in the same manner.

When the main washing step is finished, the rinsing administration step (S200) is performed. As described above, it is preferable to use a liquid detergent in the delicate course. Therefore, it is possible to discharge enough residual detergent through two rinsing processes.

Of course, as with the wool course, intermediate dehydration can be omitted. Specifically, the gantal may not be omitted, and only the main gall may be omitted. In addition, the drum drive in the rinsing process is preferably a tumbling motion. This tumbling motion has the effect of dispersing the laundry. In other words, the surface of the laundry is evenly contacted with the washing water to effectively discharge the residual detergent. In this case, the washing water level is also preferably high. Of course, the drum driving in the rinsing process may be a combination of tumbling motion and swing motion.

On the other hand, when the rinsing administration step (S200) is finished, the dehydration administration step (S300) is performed, the course is all finished. RPM during dehydration is preferably set so as not to exceed 800 RPM, like the wool course. Due to the low water content due to the nature of the fine fiber, even if dehydration is performed at a relatively low RPM, the washing water is sufficiently discharged. Of course, dehydration is preferably performed at a relatively low RPM to prevent damage to laundry due to dehydration.

Hereinafter, a control method when a sportswear course is selected will be described.

When the sportswear course is selected, washing, rinsing, and dehydrating strokes may be performed like the wool course and the delicate course. However, due to the nature of the sportswear material washing administration is preferably controlled unlike the other courses described above.

Sportswear preferably has water repellent properties. Therefore, the water content is smaller than other materials. Therefore, it is necessary to supply the wash water sufficiently and continuously to the laundry.

To this end, in particular, in the case of a sportswear course in the water supply step (S110), it is preferable to control the drum drive motion differently.

First, the drum drive motion in the detergent dissolution promoting step (S111) is preferably a scrub motion. Sportswear is less susceptible to laundry damage than wool or delicate fibers. Therefore, it is preferable to use a drum drive motion that exerts a stronger mechanical force than the swing motion.

In the detergent dissolution promoting step (S111), it is preferable that a step motion of repeating the laundry rising along the rotating drum falling out of the inner circumferential surface of the drum by braking of the drum is performed. Of course, the scrub motion may be performed in which the laundry rising along the rotating drum instead of the step motion is repeatedly raised and lowered due to braking and reverse rotation of the drum. Since the step motion and the scrub motion are motions in which the drum is suddenly stopped after rotation, the flow direction of the laundry is drastically changed. Therefore, it can be referred to as a motion in which a strong impact force is applied to the laundry. In addition, such a motion may be referred to as a motion to apply a strong impact to the wash water. Therefore, by providing a strong mechanical force at the beginning of the water supply step (S110) it is possible to promote the detergent dissolution to improve the efficiency of the washing administration.

In general, the drum is driven in a tumbling motion in the water supply stage. In other words, the laundry is lifted and dropped as the drum is continuously rotated in one direction at a constant speed.

According to the inventors' experiment, it was found that the time required for the detergent to be dissolved in the wash water was 15 minutes through this tumbling motion. In other words, it was found that the time required to saturate the detergent was 15 minutes.

On the other hand, it was found that the time required for saturation of the detergent was 9 to 10 minutes through step motion or scrub motion. In other words, it was found that the faster detergent was dissolved in the wash water through the step motion or the scrub motion. Therefore, through this motion it can be seen that it is very effective to shorten the time required to perform a specific washing course as a whole.

This is because the impact force is applied as the step motion or the scrub motion falls as well, and the strong vortex is generated in the wash water due to the sudden change of the drum rotation such as rotation and stop.

On the other hand, the drum drive motion in the detergent dissolution promoting step (S111) is preferably performed differently depending on the material of the laundry. For example, it is preferable that the cloth of cotton is performed in scrub motion, and the cloth of synthetic fiber is performed in step motion. However, the present invention is not limited thereto, and in any case, the scrub motion or the step motion may be performed.

Scrub motion is not only a drop of laundry but also a motion that causes the laundry to stretch and rub. Therefore, the effect of rubbing in the initial stage of washing process can also be expected. However, such a motion is preferably performed in a cloth resistant to friction. Therefore, the drum driving motion in the detergent dissolution promoting step (S111) of the cotton course is preferably a scrub motion.

Here, the detergent dissolution promoting step (S112) is performed for a relatively short time. Therefore, the resulting laundry damage is not a matter of concern.

In addition, it is preferable that the coating step S112 is similarly controlled unlike the wool course and the delicate course. In the case of swing motion, when the laundry is folded, the washing water may not be sufficiently supplied to the folded part. Because of the water repellent nature of sportswear. In consideration of this, it is preferable that the initiation step S112 in the sportswear course is performed in a filtration motion (including a circulation step). Through this motion, the laundry is evenly distributed in the drum, and the washing water can be evenly supplied to the laundry. In addition to such a filtration motion, a rolling motion for continuously inverting laundry may be performed.

Hereinafter, the dehydration stroke (S300) in each course will be described in detail.

The dehydration stroke (S300) may include, in particular, the liver depilation (S301), the main shell (S302) and the inflating step (S303). Ganta step (S301) is a step to evenly disperse the gun inside the drum for separation or to measure the eccentricity, and to accelerate to drum RPM for the separation. Accordingly, the inter-detachment step S301 includes a step of spin-driving the drum at approximately 100 RPM. If the separation is not performed, the de-interval step (S301) will be omitted acceleration step for the separation and only spin driving at low dehydration RPM will be performed.

When the deprivation step S301 is completed, the deprivation step S302 is performed for a predetermined time.

When the separation step (S302) is finished, the laundry is attached to the inner peripheral surface of the drum due to the centrifugal force or tangled with each other. Therefore, it is very inconvenient for the user to take out the laundry. In order to prevent this, it is very preferable that the inflating step S303 is performed after the exiting step S302 is completed. This is to loosen the tangled laundry and to minimize creases if the laundry is left unattended after the course.

The drum drive in the inflating step (S303) is preferably a step motion. In other words, the greatest impact is applied to the laundry to more effectively release the laundry. Through this, the user can easily withdraw laundry from the drum one by one without effort.

Hereinafter, a time management option will be described in detail.

In general, when a specific course is selected, driving starts according to a predetermined algorithm and the driving ends after a predetermined time elapses. Here, the driving time required for the course execution is preset by adding up the time required for the administrations constituting the course. Such driving time may be displayed on the display unit 119.

Meanwhile, depending on the current situation of the user, the driving time required when the course driving is performed for a preset time may be too long. For example, one hour after the hour to go out, the preset time may be 1 hour 20 minutes. On the contrary, the contamination of the laundry is severe and may not be sufficiently washed with one hour and 20 minutes of washing. In order to easily solve this problem, a laundry machine capable of managing time will be needed.

The laundry machine according to the present invention may include a time management option so that the option unit S118 may manage time. In other words, it is possible to increase or decrease the driving time of the selected course by selecting the time management option.

The user can select a time save option through the time management option. Conversely, the time management option allows you to choose the intensive option. If this option is not selected, driving will be performed to the preset course. This time management selection may be made after the driving course selection (S10) before performing the washing administration (S100).

For example, if the time required to select a wool course is 60 minutes, the time saving option may be 50 minutes, and the intensive laundry option may be 70 minutes. Of course, there may be some deviation between the preset time and the actual time required.

Here, it is preferable that the time required in the washing stroke and / or the rinsing stroke is varied according to the selection of the time saving option. In other words, it is preferable that the stroke in which the time required varies depending on the selected course.

In the case of the wool course, it is very important to improve the washing power and the rinsing power. This is because sensitive baby clothes must be protected by removing residual detergent as much as possible. Therefore, when the time saving option is selected and when it is not (normal), the time required for the washing operation S100 is preferably not changed. This is to ensure minimal washing power. Therefore, the time required for the rinsing stroke (S200) is preferably variable. However, since the rinsing performance is also very important, it is preferable to delete only the main body without changing the rinsing frequency.

The rinsing stroke (S200) repeats water supply, drainage, and dehydration, and it can be said that rinsing is performed twice according to the number of such repetitions, and three or four times. In addition, the dehydration may be performed in the same order as the dehydration stroke (S300) described above. However, the RPM and the departure time in the departure may be less than the dehydration stroke (S300).

In addition, when the intensive washing is selected and when it is not (normal), the time required for the washing operation S100 may be further increased. However, the time required for the rinsing stroke is preferably the same.

Such a time management option may be very convenient as the user may manage time while satisfying the purpose of a particular course.

As described above, in the embodiment of the present invention, the drum is driven in the swing motion in the washing administration step to effectively wash the laundry of the wool material, the fine fiber material and the sportswear, which are likely to be damaged. Therefore, damage to laundry can be minimized and hand washing can be implemented in a drum washing machine to provide a laundry machine that is convenient to use.

6, the amount of water detection (S30) before the water supply step (S110) is shown. As in the general course, it is possible to detect the quantity of water before the water supply step (S110) and thus change the time or actual running rate for washing.

However, if a course for washing wool, delicate fibers or sportswear is selected, this quantity detection step can be omitted. Because the quantity detection step detects the quantity of water by rotating the drum before the washing water is supplied, there is a risk of unnecessary washing time increase.

This special material of laundry is not large in quantity and is often washed immediately in case of contamination. Therefore, it is very rare to wash a large amount of laundry in one course driving. In consideration of these matters, it is preferable that the quantity detection step is omitted.

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.
