Best way to carry out the invention I. Washing machine

A washing machine and a control procedure thereof, as incorporated and described extensively herein, will be described with reference to the accompanying drawings. Figure 1 is an exploded perspective view of a washing machine according to a first embodiment as described herein extensively, in which the control procedures according to various embodiments can be applied.

Referring to Figure 1, a washing machine 100 according to a first embodiment includes a box 110 configured to define an exterior appearance thereof, a tank 120 provided in the box 110 to keep the wash water inside and a drum 130 swivel provided in the tank 120. The box 110 defines the exterior appearance of the washing machine 100. A door 113 is provided in an opening 114 of the box 110 and a user opens the door 113 to load the clothes into the box 110.

The tank 120 is provided in the box 110 to keep the wash water inside. The drum 130 can rotate in the tank 120 and can accommodate the clothes inside. In this case, a plurality of elevators 135 can be provided in the drum 130 to lift and drop the clothes during washing. The drum 130 includes a plurality of through holes 131 to allow the wash water held in the tank 120 to pass therethrough. The tank 120 can be supported by one or more springs arranged on an outer side of the tank 120. A motor 140 is mounted on a rear surface of the tank 120 and the motor 140 rotates the drum 130. When the vibration is generated by the drum 130 rotated by the motor 140, the tank 120 is vibrated in communication with the drum 130. When the drum 130 is rotated, the vibration generated in the drum 130b and in the tank 120 can be absorbed by a damper located below from Cuba 120.

As shown in Figure 1, the bowl 120 and the drum 130 can be provided substantially parallel to a base plate of the box 110. Alternatively, the rear portions of the bowl 120 and the drum 130 can be placed in an oblique orientation, with the open end of the drum 130 oriented slightly upwards to facilitate the loading of the clothes in the drum 130.

A control panel 115 may be provided in a predetermined portion of a front portion of the box 110. The user may select a program of the washing machine through the control panel 115 or recognize the information relating to the washing machine. For example, a program selection part 117 configured for the user to select a particular wash program can be provided in the control panel 115. In addition, an option selection part 118 may be provided to allow the user to adjust the operating conditions of each cycle or stage provided in the selected program and a display part 119 may be provided in the control panel 115 to display information of the Current operation of the washing machine. More details of the washing machine are described in US Patent No. 6,460,382 B1 issued on October 8, 2002 and in U.S. Application No. 12 / 704,923 filed on February 12, 2010, whose full disclosures are incorporated by reference herein.

Figure 2 is an exploded perspective view of a washing machine according to another embodiment as described herein extensively. A washing machine according to various embodiments as described herein may include a vat fixedly supported in a box, or a vat supported in a box through a flexible structure, such as a suspension unit, and without being therefore fixedly secured thereto, as shown in Figure 2. In addition, the support structure of the tank can be between a support through the suspension unit and the complete fixing structure. That is, the tank can be supported flexibly through a suspension unit that will be described later, it can be fixedly supported to be in a more rigidly supported state than the previously flexibly supported state. In alternative embodiments, the washing machine can be provided without a box. For example, an installation space of a built-in type washing machine can be defined by a wall structure instead of a box. That is, in certain embodiments, a box configured to form an independent exterior appearance may not be provided.

Referring to Figure 2, a tank may include a front portion 200 of the bowl and a rear portion 220 of the bowl that forms a rear portion of the front portion 200 of the bowl. The front part 200 of the tank and the rear part 220 of the tank can be mounted by means of screws or other appropriate fixing mechanism, and a predetermined space is formed inside to accommodate a drum. The rear part 220 of the tank includes an opening formed on a rear surface thereof and a rear joint 250 can be connected to an inner circumference of the opening. The rear joint 250 can be connected to a back 230 of the tank and the back 230 of the tank can include a through hole having an axis passing through a center thereof.

The rear joint 250 is sealed and connected to each of the back 230 of the tank and the rear part 220 of the tank to prevent the washing water from leaking from the tank. Since the reverse 230 of the bowl vibrates when the drum is rotated, the reverse 230 of the bowl may be away from the rear portion 220 of the vessel at a predetermined distance so as not to interfere with the rear portion 220 of the vessel. In addition, the back joint 250 may be formed of flexible material to allow the back 230 of the tank to move relatively, without interfering with the back portion 220 of the tank. The rear joint 250 may include a corrugated part that is extensible to a length sufficient to allow relative movement of the back 230 of the tank. This embodiment presents the rear joint 250 connected to the back 230 of the tank and the present invention is not limited to this. The rear joint 250 is configured to seal the gap between the tank and an actuating part (not shown) that includes a shaft 351 and a bearing housing 400 and to allow the actuating portion to move relatively with respect to the vessel. As a result, the connected shapes and objects of the subsequent joint 250 can be unlimitedly variable, only if this function is enabled. A flexible material 280 which will be described as the front gasket later can be installed in a front portion of the front part 200 of the tank.

The drum can be configured from a front part 300 of the drum, a center 320 from the drum and a rear part 340 from the drum. Ball balancers 310 and 330 can be installed in the front and rear portions of the drum, respectively. The rear part 340 of the drum can be connected to a crosshead 350 and the crosshead 350 can be connected to the shaft 351. The drum can rotate inside the tank by a rotational force transmitted through the shaft 351.

The shaft 351 can be connected to a motor and pass through the reverse 230 of the tank. In certain embodiments, the motor can be connected to the axis 351 concentrically. In certain embodiments, the motor can be connected directly to the axis 351 and, in particular, a motor rotor can be connected directly to the axis 351. In alternative embodiments, the motor and the axis 351 can be indirectly connected to each other, for example, They can be connected by a strap.

The bearing housing 400 can be secured to the back 230 of the tank to rotatably support the shaft, between the motor and the reverse 230 of the tank. A stator can be fixedly secured to the bearing housing 400. And the rotor can be placed around the stator. As mentioned above, the rotor can be connected directly to the shaft 351, the motor being an external rotor type motor that can be connected to the shaft directly. The bearing housing 400 can be supported by a base 600 through the suspension unit. The suspension unit may include a perpendicular suspension and an oblique suspension configured to support the bearing housing 400 with respect to a forward and backward direction. For example, the suspension unit according to this embodiment may include three perpendicular suspensions 500, 510 and 520 (vertical, as shown in Figure 2) and two oblique suspensions 450 and 530 (angled, or inclined, as shown in Figure 2) configured to support the bearing housing 400 with respect to a forward and backward direction. The suspension unit can be connected to the base 600 with a predetermined elastic transformation that allows a backward and / or right / forward / left movement of the drum, and therefore is not fixedly connected. That is, the suspension unit can be supported by the base, with sufficient predetermined elasticity to allow rotation at a predetermined angle in forward / backward and right / left directions relative to the points connected to the base . For such elastic support, the perpendicular suspension can be installed in the base by a rubber bushing or other mechanism as appropriate.

The perpendicular suspension of the suspension unit can suspend the vibration of the drum elastically and the oblique suspension can dampen the vibration. That is, the perpendicular suspension can be used as a spring and the oblique suspension as damping means in a vibration system that includes a spring and damping means.

The tank is supported in the box and the vibration of the drum can be damped by the suspension unit. As a result, the washing machine according to this embodiment may have a substantially independent support structure between the tank and the drum or it may have a structure that does not transmit the drum vibration directly to the tank.

II. Drum flipping movement

The diversification of the drum drive movements and combinations thereof, as incorporated and described extensively herein, can provide significant improvements in washing capacity, noise / vibration, energy consumption, and customer satisfaction. A control procedure that provides improved washing capacity will be described. The effect of hand washing can be done by various patterns of movement of clothing. For example, the effect of hand washing can be performed by a combination of massage and / or unraveling movements and / or impact and / or oscillation and / or rubbing and / or compression / filtration.

Such different clothing movement patterns can be implemented by various drum drive movements and combination or combinations of different drum drive movements. Drum drive movements may include combinations of turning directions and

turning speeds The clothes found in the drum can have different directions of fall, drop points and fall distance due to the drum drive movements. Because of that, the clothes can have different displacements inside the drum. The drum drive movements can be performed, for example, by controlling the direction of rotation and / or speed of the motor that drives the drum.

When the drum is rotated, the clothes are lifted by one or more elevators 135 provided on the inner circumferential surface of the drum. Because of that, the direction of rotation of the drum can be controlled and the impact applied to the clothing can be varied accordingly. That is, a mechanical force applied to clothing such as the friction generated between clothes, the friction generated between clothes and water, and the impact of falling clothes can be varied. In other words, a degree of impact or rubbing applied to clothes for laundry can be varied and a degree of distribution of the laundry or spin inside the drum can be varied accordingly.

As a result, such a control procedure of the washing machine can provide various drum drive movement and drum drive movements are varied according to each of the cycles and a specific stage that composes the cycle, in such a way An optimal mechanical force can be used to treat clothes based on the type of clothes being washed, the level of dirt, and other factors. Because of that, the effectiveness of laundry washing can be improved. In addition, excessive time required by the typical drum drive movement can be avoided.

In certain embodiments, to incorporate such various drum drive movements, the motor 140 may be a type of direct connection. That is, the motor can have a stator fixed to a rear surface of the tank 120 and a rotor that rotates the drum 120 directly. Since the direction of rotation and the torque of the direct connection type motor can be controlled, the time delay or reaction can be avoided and then the drum drive movement can be controlled as appropriate.

In contrast, drum drive movements that allow time or reaction delay, for example, a flip motion or flip motion, can be performed on an indirect connection type motor that includes a pulley such that its torque It can be transmitted to an axle through the pulley. However, the indirect connection type motor may have limited applicability.

The drum drive movement can be performed by the control of the motor 140. As a result, the engine control procedure can be diversified and then the various drum drive movements can be achieved.

The patterns of movement of the clothes and the driving movement of the drum to achieve the pattern of movement of the clothes will be described in detail later.

A movement pattern of clothing massage can be achieved if friction between the clothes and the drum is maximized. For example, when the drum is rotated continuously in a predetermined direction at a predetermined speed or less, the clothes can be rocked to achieve the massage effect. If the speed of rotation of the drum driven in the flipping movement is defined as a reference speed, the predetermined speed may be the reference speed. For example, a drum drive movement configured to rotate the drum at a predetermined speed or less in a predetermined direction can be defined as 'turning movement'.

A unraveling movement pattern can be performed by, for example, a flipping movement. The flipping movement can be defined as a movement configured to continuously rotate the drum at the reference speed in a predetermined direction. The unraveling movement pattern drops the clothes contained in the drum, with a medium level drop distance and a friction of medium magnitude.

An impact movement pattern can be achieved by dropping the clothes contained in the drum at a maximum drop distance. For example, if the drum is rotated at the reference speed or more to raise the clothes to the highest point inside the drum, and then the drum suddenly brakes, such an impact effect can be achieved. This drum drive movement can be defined as 'progressive movement'.

An oscillating movement pattern can be achieved when the drum is rotated at a predetermined speed lower than the reference speed in the clockwise / counterclockwise direction. Such drum drive movement can be defined as 'swing movement'.

A rubbing movement pattern can be achieved when the friction between the clothes and the drum is increased. For example, if the drum rotates at the reference speed or more clockwise, it brakes suddenly and then is rotated counterclockwise, the clothes move along the inner circumferential surface of the drum from a predetermined high point of the drum. drum. Such drum drive movement can be defined as 'rubbing movement'.

A compression and filtration movement pattern can be achieved if the wash water is supplied while

Spins the drum at reference speed or more. Once the drum is rotated at a relatively high speed, the clothes can unfold, or spread and cling along the inner circumferential surface of the drum and then, the washing water that is sprayed into the drum is passed to Through clothing and then clothing can be squeezed to improve the effect of rinsing. A drum drive movement of this type can be defined as 'filtration movement'.

Various drum drive movements configured to achieve the various previous movement patterns of the clothing will be described with reference to the drawings.

Figure 3 is a diagram of various drum drive movements as incorporated and described extensively herein.

Figure 3 (a) is a diagram of a turning movement. In the turning movement, the motor 140 continuously rotates the drum 130 in a predetermined direction and the clothes that are on the inner circumferential surface of the rotating drum along the direction of rotation of the drum are dropped from the position in an angle approximately less than 90 ° with respect to the drum of rotation of the drum to the lowest point of the drum.

That is, once the motor 140 rotates the drum at a speed that is less than a reference turning speed (turning speed), for example, at approximately 40 RPM, the clothes that are at the point lower of the drum 130 rises to a predetermined height along the direction of rotation of the drum 130 and then the clothes move rolling to the lowest point of the drum from the position of less than 90 ° with respect to the direction of rotation of the drum from the lowest point of the drum. Visually, in case the drum is turned clockwise, the clothes are continuously rolling in a third quadrant of the drum.

The laundry is washed by the maximum friction with the washing water and the maximum friction with other garments and the maximum friction with the inner circumferential surface of the drum in the turning movement. This turning movement allows enough turning of the clothes to generate a gentle washing effect similar to the massage. The drum RPM of the drum drive movement can be determined based on a relationship with respect to a drum radius. That is, the higher the RPM of the drum, the greater the centrifugal force generated in the clothes contained in the drum. A difference between the magnitude of the centrifugal force and the force of gravity applied to the clothes in the drum differentiates the point at which the clothes are dropped and the corresponding movement of the clothes contained in the drum. Both the rotational force of the drum and the friction between the drum and the clothes can also be considered. Therefore, the RPM of the drum in the turning movement can be determined to allow the generated centrifugal force and friction force to be less than gravity (1G).

Figure 3 (b) is a diagram of a flipping movement. In the turning movement, the motor 140 continuously rotates the drum 130 in a predetermined direction and the clothes that are on the inner circumferential surface of the drum are dropped from the position of approximately 90 ° to 110 ° with respect to the direction of rotation of the drum to the lowest point of the drum. If the drum is controlled to be rotated at a suitable RPM in a predetermined direction, a mechanical force can be generated between the clothes and the drum in the flipping motion. Because of that, the flipping movement can be used in washing and rinsing.

That is, the laundry loaded on the drum 130 is at the lowest point of the drum 130 before the motor 140 is driven. When the motor 140 provides a torque to the drum 130, the drum 130 is rotated and the elevator 135 provided on the inner circumferential surface of the drum raises the clothes to a predetermined height from the lowest point of the drum. If the motor 140 rotates the drum 130 at the reference rotation speed, for example, at approximately 46 RPM, the laundry can be raised to the position of approximately 90 ° to 110 ° with respect to the direction of rotation of the drum and then get off to the lowest point of the drum. In the turning movement, the RPM of the drum can be determined to allow the centrifugal force generated to be greater than the centrifugal force generated in the rotation movement and to be less than gravity.

Visually, if the drum is rotated clockwise in the flipping motion, the clothes are raised sequentially to the third quadrant and a part of a second quadrant from the lowest point of the drum. After that, the clothes are dropped to the lowest point of the drum. As a result, the flipping movement allows the clothes to be washed by the impact generated by friction with the washing water and the impact of falling. Because, in the turning movement, a mechanical force greater than the mechanical force of the turning movement can be used to implement washing and rinsing. Also, the turning movement can be effective in separating tangled clothes and distributing clothes evenly.

Figure 3 (c) is a diagram of a progressive movement. In the progressive movement, the motor 140 rotates the drum 130 in a predetermined direction and the clothing that is located on the inner circumferential surface of the drum is controlled to drop to the lowest point of the drum from the highest point (approximately 180 ° ) with respect to the direction of rotation of the drum. Once the motor 140 rotates the drum 130 at a speed that is greater than the reference turning speed (turning speed), for example, approximately 60 RPM or more, the clothes can be rotated by the centrifugal force until reaching the highest point of the drum, without

to drop In the progressive movement, the drum is rotated at a predetermined speed so that the clothing is dropped, and then suddenly braked to maximize the impact applied to the clothing as it is dropped.

After rotating the drum 130 at the predetermined speed where the clothes cannot be dropped (approximately 60 RPM or more) until the clothes are near the highest point of the drum, the motor 140 supplies a reverse torque in the drum 130 with clothes that are near the highest point of the drum (180 ° with respect to the direction of rotation of the drum). Therefore, the clothes rise from the lowest point of the drum 130 along the direction of rotation of the drum, the drum stops momentarily by the reverse torque of the motor, and the clothes are dropped from the highest point to the lowest point of the drum 130. The progressive movement allows the clothes to be washed by the impact generated while the clothes are dropped with the maximum height difference.

Visually, in the progressive movement, after moving from the lowest to the highest point of the drum as the drum is rotated, the fall distance inside the drum is the largest in the progressive movement, and the Mechanical strength of progressive movement can be applied to a small amount of clothing effectively. The motor 140 can be braked in reverse phase in the progressive movement using a torque generated in an inverse direction with respect to a direction of rotation of the motor. A phase of a current supplied to the motor can be reversed to generate an inverse torque in a direction of reverse rotation of the motor and the reverse phase brake allows the application of sudden braking. The reverse phase brake can be used to apply the strong impact to the clothing.

Therefore, after applying the torque to rotate the drum clockwise, the torque is applied to rotate the drum counterclockwise and the drum suddenly brakes. After that, a pair is applied to the drum to rotate it clockwise and the progressive movement materializes. The progressive movement can be used to wash the clothes using the friction between the water extracted through the through hole 131 formed in the drum and the clothes and with the impact generated by the fall of the clothes when the clothes reach the highest point of the drum. This progressive movement can generate a washing effect of 'impact washing' type.

Figure 3 (d) is a diagram of a swing movement. In the oscillating movement, the motor 140 rotates the drum 130 in clockwise and counterclockwise directions alternately and the clothes are dropped in a position approximately less than 90 ° with respect to the direction of rotation of the drum. That is, once the motor 140 rotates the drum 130 at a speed that is lower than the reference turning speed (turning speed), for example, at approximately 40 RPM counterclockwise, the clothes that located at the lowest point of the drum 130 rises to a predetermined height along the counterclockwise direction. Before the clothes reach the position of approximately 90 ° with respect to the counterclockwise direction of the drum, the motor stops the rotation of the drum and the clothes are dropped to the lowest point of the drum from the position approximately below 90 ° with respect to the drum direction counterclockwise.

Therefore, the motor 140 rotates the drum 130 at a speed that is lower than the reference turning speed (turning speed), for example, approximately 40 RPM clockwise to raise the clothes a predetermined height clockwise along the direction of rotation of the drum. Before the clothes reach the position of approximately 90 ° with respect to the counterclockwise direction of the drum, the motor stops the rotation of the drum and the clothes are dropped to the lowest point of the drum from the position of less than 90 ° with respect to clockwise drum.

Therefore, the oscillation movement is a movement in which the turn and stop with respect to a first direction and the turn and stop with respect to a second (opposite) direction can be repeated. Visually, clothing that rises to a part of the second quadrant from the third quadrant of the drum is dropped gently, and is raised again to a part of the first quadrant from a fourth quadrant of the drum and gently dropped, repeatedly.

In certain embodiments, the motor 140 can use the rheostatic braking and a load applied to the motor 140 so that a mechanical abrasion of the motor 140 can be reduced, and the impact applied to the clothing can be adjusted. When using rheostatic braking, if a current applied to a motor is disconnected, the motor functions as a generator because of the inertia of rotation, and a sense of the current flowing in a motor coil will change in a reverse direction before the Power disconnection and a force (Fleming's right hand rule) is applied along a turn that interferes with the motor's turn, to brake the engine. Unlike reverse phase braking, rheostatic braking does not generate sudden braking but changes the direction of rotation of the drum smoothly. As a result, the clothes can be moved in a figure-8 shape on the third and fourth quadrants of the drum in the oscillating movement. The oscillation movement can generate a wash similar to 'the oscillation of clothes'.

Figure 3 (e) is a diagram of a rubbing movement. In the rubbing movement, the motor 140 rotates the drum 130, in both directions clockwise and counterclockwise alternately and the clothes can be dropped from the position of more than 90 ° with respect to the direction of rotation of the drum.

That is, once the motor 140 rotates the drum 130 at a speed that is greater than the speed of rotation

reference (turning speed), for example, approximately 60 RPM or more in the counterclockwise direction, the clothes that are at the lowest point of the drum 130 are raised a predetermined height in the counterclockwise direction. After the clothes move to an approximately 90 ° position with respect to the counterclockwise direction of the drum, the motor provides a reverse torque in the drum to temporarily stop the drum, and the clothes that are on the inner circumferential surface of the drum can be drop quickly. As a particular result, the clothes found on the inner circumferential surface of the drum are dropped to the lowest point of the drum from the position of 90 ° or more with respect to the clockwise direction of the drum. Therefore, clothes can be left quickly from the predetermined height, in the rubbing movement. Motor 140 may use reverse torque phase braking to brake the drum.

In the rubbing movement, the direction of rotation of the drum is changed rapidly and the clothes may not be far from the inner circumferential surface of the drum for a long period of time. Because of that, a washing effect similar to strong friction by maximized friction between the clothes and the drum can be achieved in the rubbing movement. In the rubbing movement, clothing that has moved to a part of the second quadrant through the third quadrant is dropped quickly and then dropped again after having moved back to a part of the first quadrant through the fourth quadrant . As a result, visually, in the rubbing movement, the clothes that have been raised are dropped along the inner circumferential surface of the drum repeatedly.

Figure 3 (f) is a diagram of the filtration movement. In the filtration movement, the motor 140 rotates the drum 130 so that the clothes are not dropped from the inner circumferential surface of the drum, and the wash water is sprayed into the drum. That is, in the filtration movement, the clothes extend along and maintain close contact with the inner circumferential surface of the drum as the washing water is sprayed into the drum. Water is discharged out of the tank through the through holes 131 of the drum by centrifugal force. Since the filtration movement spreads / expands a surface area of the clothes and allows water to pass through the clothes, the wash water can be supplied to the clothes evenly.

Figure 3 (g) is a diagram of the compression movement. In the compression movement, the motor 140 rotates the drum 130 so that the clothing adheres to / is not dropped from the inner circumferential surface of the drum by centrifugal force, and then the motor reduces the speed of rotation of the drum 130 to temporarily separate the clothes from the inner circumferential surface of the drum. This procedure is repeated and water is sprayed into the drum during drum rotation. That is, the drum is continuously rotated at a speed that is high enough not to drop the clothes from the inner circumferential surface of the drum in the filtration movement. In contrast, in the compression movement, the speed of rotation of the drum is changed to repeat the laundry casting process and to separate it from the inner circumferential surface of the drum 130.

The spraying of the wash water in the drum 130 in the filtration movement and in the compression movement can be implemented by, for example, a circulation path and a pump. The pump can communicate with the bottom surface of the tank 120, with one end of the circulation path connected to the pump so that the washing water is sprayed from the tank in the drum through the other end of the circulation path .

In alternative embodiments, the wash water can be sprayed into the drum through a supply path connected to an external water supply source located outside the box. That is, one end of the supply path is connected to the external power supply and the other end thereof is connected to the tank. If a nozzle is provided for spraying wash water into the drum, the wash water can be sprayed into the drum, either in one or both of the filtration and compression movements.

Figure 4 is a diagram of the progressive movement in more detail.

First, the clothes move from a lower point to a higher point of the drum 130 as shown in Figures 4 (a) - (c). As described with respect to the tank 120 which is still placed adjacent to the drum 130, the clothing received in the drum 130 moves from a position adjacent to the lowest point of the tank 120 to the highest point of the tank 120. For such movement of the clothes, the motor 140 applies a turning force, in particular, a turning torque to the drum in a predetermined direction, which is one clockwise as shown in the drawings, and the drum 130 is rotated along the predetermined direction along with the clothes, to raise the clothes.

The clothes can be rotated together with the drum, in close contact with an inner surface of the drum 130 by a frictional force with elevators and the inner circumferential surface of the drum 130. The clothes are raised to the highest point of the drum 130, without separating from drum 130 by rotating drum 130 at about 60 RPM or more, since this rotation speed generates a predetermined centrifugal force sufficient to prevent clothing from separating from drum 130 to the highest point of drum 130.

The speed of rotation of the drum can be changed so that the generated centrifugal force is greater than gravity, allowing the clothes to rotate together with the drum from the lowest point of the drum 130, which is a

55

predetermined point of the inner surface of the drum adjacent to the lowest point of the tank 120 to the highest point of the tank 120. The clothes are dropped from the highest point of the drum 130 to the lowest point of the drum 130 when the Drum 130 suddenly brakes, either at or just before the clothes reach the highest point of the drum 130.

Specifically, to suddenly brake drum 130, motor 140 provides drum 130 with an inverse torque. The reverse torque is generated by the reversed phase braking configured to supply the reverse phase currents to the motor 140, as described with reference to Figure 3 (c). Reverse phase braking is a type of motor braking that uses a torque generated in a reverse rotation with respect to a direction of motor rotation. A phase of a current supplied to the motor can be reversed to generate an inverse torque in a direction of reverse motor rotation and reverse phase braking, allows the application of sudden braking on the motor. For example, as shown in the drawing, a current is applied to the motor to rotate the drum clockwise and then a current is applied to the motor to turn the drum counterclockwise suddenly.

The time point of the reverse phase braking with respect to the motor 140 may be closely related to the location of the clothing contained in the drum 130. Because of that, a device used to determine or predict the location of the clothing can be provided and a detection device such as, for example, a Hall effect sensor configured to determine a rotation angle of a rotor, can for example be such a device. The control part can determine the angle of rotation of the drum using the detection device and control the motor 140 for reverse phase braking when or just before the drum has a rotation angle of 180 °. As a result, the drum that rotates clockwise stops quickly in response to the counterclockwise torque. The centrifugal force applied to the clothes is removed and then the clothes are dropped to the lowest point.

Therefore, as shown in Figure 4 (d), the drum 130 is continuously rotated clockwise and the clothes spin / fall is repeated. Although Figure 4 shows that the drum is rotated clockwise, the drum can rotate counterclockwise to apply progressive movement. The progressive movement generates a relatively large amount of load on the motor 140 and a net acting ratio of the progressive movement can be reduced.

The net performance ratio is a ratio of a motor drive time to a total value of drive time and engine stop time 140. If the net performance ratio is '1', this means that the engine It is operated without a downtime. The progressive movement can be implemented in approximately 70% of the net operating ratio, taking into account the engine load. For example, the engine can be stopped for 3 seconds after 10 seconds. Other ratios and drive / stop times may also be appropriate.

Before the falling clothes reach the lowest point of the drum, that is, while the clothes are dropped, the drum 130 begins its rotation to implement the next progressive movement. In this case, the drum 130 is rotated at a predetermined angle and after the clothes it reaches the lowest point of the drum 130. From this point, the clothes and the drum can rotate together. Although the drum is rotated 180 ° as set, the clothes cannot be rotated 180 °, that is, the highest point of the drum 130 and it cannot be dropped from the highest point to obtain the capacity of desired wash.

Because of that, the drum 130 is controlled to rotate again as shown in Figure 4 (d) after the clothes reach the lowest point of the drum. That is, the drum is held in a stopped position until the clothes reach the lowest point of the drum. More specifically, at the moment when the clothes really start to fall, the drum stop 130 is generated. From the point of fall in time to the point where the clothes reach the lowest point of the drum, it remains stopped and Does not turn. The stop time may be longer than the time necessary for the clothes to fall to the lowest point (point 1) from the highest point of the drum. As a result, the drum may remain stopped for, for example, 0.4 seconds, or in certain embodiments, 0.6 seconds, to ensure sufficient time in the stop state. This allows progressive movement to be implemented more precisely to generate maximum impact and the desired washing capacity can be achieved accordingly.

Figure 5 is a diagram of the rubbing movement in more detail.

First, the clothes move from the lowest point of the drum 130 to a position reached after 90 ° or more clockwise rotation of the drum 130, as shown in Figures 5 (a) - (c). As described with respect to the tank 120 stopped adjacent to the drum 130, the clothing contained in the drum 130 moves from the predetermined point of the surface of the inner drum adjacent to the lowest point of the bowl 120 to the point of the surface of the inner drum rotated 90 ° or more along the clockwise direction of the drum 120. To generate such movement of the laundry, the motor applies a rotational force, that is, a torque to the drum 130 in a predetermined direction, (in the sense schedule) and then drum 130 is rotated together with the clothes to lift the clothes.

The clothes are rotated together with the drum, in close contact with the inner circumferential surface of the drum 130 by the elevator and friction with the inner circumferential surface of the drum, and does not separate from the drum 130. For this, the drum is made rotate at approximately 60 RPM or more to generate enough centrifugal force to

5

10

fifteen

twenty

25

30

35

40

Four. Five

55

that the clothes do not separate from the drum 130. The speed of rotation of the drum can be configured to generate a centrifugal force greater than gravity by taking the size of the drum, such as an inner diameter, under consideration. As a result, the clothes are rotated together with the drum from the lowest point of the drum to the position of 90 ° or more rotation with respect to the lowest point of the drum.

The clothes are then dropped, from the 90 ° position or more turn to the lowest point. For this fall of the clothes, the drum 130 suddenly brakes when the clothes reach the 90 ° position or more rotation of the drum. Motor 140 provides drum 130 with an inverse torque to apply a sudden brake to the drum. As mentioned above with reference to Figure 3 (e), the reverse torque is an inverse torque generated by the reverse phase braking configured to supply reverse phase currents to the motor 140.

The control part can determine a rotation angle of the drum by using a detection device as described above. Once the rotation angle of the drum is 90 ° or more, the control part can control the motor 140 to brake in reverse phase. As a result, the drum 130 which rotates clockwise is provided with a counterclockwise torque to momentarily stop the rotation and remove the centrifugal force applied to the clothing. As shown in Figure 5 (c), the clothing cannot fall perpendicularly due to the counterclockwise torque, but falls to the lowest point of the drum obliquely towards the inner circumferential surface of the drum. Due to the inclined fall, the clothes can have a relatively large amount of friction with the inner surface of the drum in the middle of the fall and the simultaneous friction between the clothes and between the clothes and the wash water can be relatively large .

Therefore, as shown in Figure 5 (d), the drum 130 is rotated counterclockwise continuously and the rotation / fall of the aforementioned clothing can be repeated. Figure 5 shows that the drum is rotated clockwise before, but the counterclockwise rotation can be implemented before. The rubbing movement generates a relatively large load applied to the motor 140, as does the progressive movement, and the net actuation ratio of the rubbing movement can be reduced, for example, a stop of 3 seconds after the rubbing movement can be repeated and The net acting ratio of the rubbing movement can be controlled to be 70%. Other provisions may also be appropriate.

Before the falling clothes reaches the lowest point of the drum, that is, while the clothes are dropped, the drum 130 begins its rotation in the reverse direction to implement the next progressive movement. In this case, the drum 130 is rotated at a predetermined angle and then the clothes reach the lowest point of the drum 130. From this point, the clothes and the drum can rotate together. Although the drum is rotated at 90 ° as set, the clothes cannot be rotated by 90 °, that is, the highest point of the drum 130 and cannot be dropped from the highest point to obtain the washing capacity desired.

Because of that, the drum 130 is rotated again as shown in Figure 5 (d) after the clothes reach the lowest point of the drum. That is, the drum is controlled to keep stopped that the clothes reach the lowest point of the drum. More specifically, at the moment when the clothes actually begin to fall, the stopping of the drum 130 is generated. From the point in time the clothes are dropped until the clothes reach the lowest point of the drum, the drum will keeps in the stopped state and does not turn. The time period of the drum stop state may be longer than the time necessary for the clothes to fall to the lowest point of the drum. As a result, the stop state maintained by the drum can be set, for example, in 0.2 seconds, which is less than the stop state of the drum in the progressive movement.

Since such a stop state maintained by the drum is established, the progressive movement can be implemented more precisely in order to generate maximum friction between the surface of the inner drum and the clothes, the maximum friction between the washing elements and the Maximum friction between the laundry and the wash water and the desired washing capacity can be achieved accordingly.

Figure 6 is a graph that compares the washing capacity and vibration level of each movement shown in Figure 3. A horizontal axis shows the washing capacity, with an easier separation of the contaminants contained in the clothes moving toward the left. A vertical axis presents the level of vibration or noise, with the highest levels moving up, with a reduced washing time for the same clothes.

The progressive movement and the rubbing movement are typical of washing programs implemented to reduce the washing time when the clothes have excessive contaminants. The progressive movement and the rubbing movement have a high level of vibration / noise and are generally not used to wash sensitive fabrics and / or to minimize noise and vibration.

The turning movement has a good washing capacity and a low level of vibrations, with minimal damage to the clothes and low engine load. As a result, the turning movement can be used in all washing programs, especially to help detergent dissolution at an initial washing stage and to moisten clothes.

The turning movement has a lower washing capacity compared to the rubbing movement and a medium vibration level compared to the rubbing movement and the turning movement. The turning movement has a lower vibration level, but has a longer washing time than the turning movement.

Because of that, the flipping movement can be applicable to all washing programs and can be effective in a washing program to distribute clothes evenly.

The compression movement has a washing capacity similar to the turning movement and a higher vibration level than the turning movement. The compression movement repeats the procedure of extracting the clothes towards and separating the clothes from the inner circumferential surface of the drum. In this procedure, the wash water is discharged out of the drum after passing through the clothes. Therefore, the compression movement can be applied to clarify.

The filtration movement has a lower washing capacity compared to the compression movement and a noise level similar to the turning movement. In the filtration movement, water is passed through the clothes and discharged out of the drum, with the clothes in close contact with the inner circumferential surface of the drum. As a result, the filtration movement can be applied to a program to moisten clothes.

The oscillation movement has the lowest vibration and wash capacity and can be applied in a low noise and low vibration washing program and in a program for washing sensitive or delicate items.

As mentioned above, each drum drive movement has its own advantages and it is preferable that these various drum drive movements be used to maximize the advantages. Each drum drive movement can also have advantages and disadvantages in relation to the amount of clothing. Even in the case of the same program and cycle, the various drum drive movements can be applied differently depending on the relationship with the amount of clothing.

An interior of the drum in the drum type washing machine can be visible from the outside through the door. The various drum drive movements can be implemented in a washing program that will be described later. As a result, the user can see the different drum drive movements implemented inside the drum. That is, a gentle impact type wash (flip motion), a strong impact type wash (progressive movement), smooth rub type wash (spin motion) and a strong rub type wash (rub motion) can be identified. Visibly Because of that, the user may feel that the washing is implemented correctly, which can generate an improved satisfaction on the part of the user, in addition to a substantially improved washing efficiency.

III. Washing machine programs

Various control procedures will be described below, that is, various programs of a washing machine as incorporated and described extensively herein.

A. Cycle A (standard program)

Program A will be described with reference to Figure 7. Program A is a standard program that can be used to wash normal clothes without any auxiliary options. Program A includes a wash cycle, a rinse cycle and a spin cycle. The user can select the standard program in a program selection part 117 (S710).

A.1 Washing cycle (S730):

The wash cycle includes a water supply stage (S733) that supplies washing water and detergent to a tank 120 or drum 130 to dissolve the detergent in the wash water, and a washing stage (S742) configured to operate The drum for washing clothes. In the water supply stage, the water is supplied from an external water supply source to the washing machine, together with the detergent. By improving the efficiency of the water supply stage in the preparation for the washing stage, the effectiveness of the washing cycle can also be achieved, including washing efficiency and reducing washing time.

A.1.1 Determination (S731) of the quantity of clothing:

As mentioned above, the water supply stage is performed in preparation for the main wash stage. As a result, detergent solution, wetting clothes and the like, can be implemented quickly and completely. However, taking into account the capacity of the drum and the amount of washing water supplied to the drum, a drum drive movement can be controlled according to the amount of the laundry in the drum in the water supply stage. That is, a drum drive movement capable of performing detergent dissolution and wetting of clothes can be selected more efficiently based on the amount of laundry in the drum.

A step of determining the amount of clothes configured to determine the amount of clothes housed in the drum can be implemented before the water supply stage. Based on the amount of clothing determined, the drum drive movement can be differentiated in the water supply stage.

A quantity of clothing can be determined by measuring the electric currents that are used to

5

10

fifteen

twenty

25

30

35

40

Four. Five

55

actuate the drum For example, the currents used to apply a flipping motion can be measured. To implement the flip motion, a control part controls the drum for rotation at a predetermined RPM, for example, 46 RPM. A value of the current required to operate the drum in that RPM may be different, depending on the amount of clothing in the drum. Therefore, the amount of clothing can be determined based on a quantity of current required to drive a particular drum at a particular RPM, in a particular movement.

If the amount of clothing is relatively large, sufficient washing water can be supplied to the clothes at an initial stage of the water supply stage and the washing efficiency of the washing can be further improved. The driving movement of the drum can be differentiated according to the amount of laundry in the water supply stage and the parameters of the water supply stage can be determined appropriately.

A.1.2 Water supply (S733):

A.1.2.1 Determination (S734) of the type of detergent:

In the initial stage of the water supply stage, a detergent type determination stage can be implemented to determine if the detergent supplied during the initial stage of the water supply stage is a powder type or a liquid type. This step is performed to determine a drum drive movement or the number of rinses in the rinse cycle that will be applied after the wash cycle. Information regarding the wash cycle and rinse cycle may be available to the user through a display part 119 in an initial operation of the washing machine. Because of that, the detergent type determination stage can be implemented in the initial stage of the water supply stage, specifically, before a stage of which stage of promoting the detergent solution.

A.1.2.2 Promotion (S735) of detergent solution:

As the wash water and detergent are supplied in the water supply stage, the detergent dissolution stage can be implemented. To improve the effectiveness of the wash cycle, the detergent can be dissolved more completely and efficiently in the initial stage of the water supply stage. As a result, the stage of promoting the detergent solution can be implemented in the water supply stage to promote the detergent solution.

A movement, in particular, the driving movement of the drum to move the laundry contained in the drum to promote detergent dissolution may be a movement configured to supply a strong mechanical force in the wash water and in the laundry. For example, a progressive movement configured to repeatedly lift the clothes along the rotating drum and drop the clothes from an inner circumferential surface of the drum according to a brake applied to the drum can be implemented at the stage of promoting detergent dissolution. . Alternatively, a rubbing movement configured to lift the clothes along the rotating drum and drop the clothes according to the brake and reverse the rotation of the drum to re-lift the clothes can be implemented instead of the progressive movement. The progressive movement and the rubbing movement are movements configured to apply a sudden brake to the rotating drum to suddenly change the direction of clothing movement and apply a strong impact to the clothing. In addition, the progressive movement and the rubbing movement are configured to also apply the strong impact to the wash water. As a result, strong mechanical force is provided in the initial stage of the water supply stage to promote detergent dissolution and improve the efficiency of the wash cycle accordingly.

In alternative embodiments, the stage of promoting the detergent solution can be implemented by repeating the sequential combination of the progressive movement and the rubbing movement. In this case, two types of drum drive movements are combined several times and the wash water flow patterns can be more diversified to improve the efficiency of the wash cycle.

In a conventional water supply stage, the drum is actuated in the turning movement that continuously rotates the drum in a predetermined direction at a predetermined speed to raise and drop the clothes. However, it has been found that the time taken to dissolve the detergent in the wash water in the turning movement may be greater in either the stage or rubbing movements, or a combination thereof. For example, the time to dissolve detergent in the turning movement in an exemplary washing machine can be approximately 15 minutes, while the time it takes to dissolve the detergent in the washing water in the progressive movement or rubbing movement using the same washing machine It can be from 9 to 10 minutes. Therefore, the progressive movement or rubbing movement can dissolve the detergent in the wash water more quickly, and the corresponding time of the specific washing program is reduced.

In progressive and rubbing movements, the clothes are dropped and the fall impact is applied to the clothes, while the rotation and stopping of the drum can generate a strong vortex in the wash water.

In addition, a circulation stage configured to circulate the washing water contained in the tank and re-supplying the washing water to the drum can be implemented at which stage of promoting the detergent solution. In the circulation stage, the wash water contained below the drum is supplied inside the drum,

5

10

fifteen

twenty

25

30

35

further promoting the dissolution of detergent and the wetting of clothes.

In certain embodiments, the step of promoting the detergent solution may be implemented for, for example, approximately 2 minutes, or another period of time as appropriate, until the water supply is completed. The water supply can be completed at which stage of promoting the detergent solution or the water can be supplied, in addition, because a water level can decrease in a next stage of wetting clothes. The step of promoting the detergent solution can be implemented for a relatively short time so that no significant impact damages the wash fabric. As a result, a drum drive movement in the stage of promoting the detergent dissolution of each previous program may be the rubbing movement, depending on a quantity of clothes in the drum.

That is, the step of promoting the detergent solution can be implemented if the amount of clothing determined is a predetermined or lower level, since the drum drive movements configured to deliver the strong mechanical force can be more effective with small amounts of washing. and because small amounts of clothing can maintain sufficient contact with the wash water. Specifically, the small amount of clothing indicates that an area of the surface of the clothing that has to come in contact with the wash water is small and that the detergent solution and the wetting of clothing can be implemented by the mechanical force applied to flip the clothes in a relatively short time. As a result, the progressive movement or the rubbing movement makes it possible to improve the washing efficiency and reduce the washing time accordingly.

On the contrary, if the amount of clothing determined at the stage of determining the amount of clothing is a predetermined or higher level, the step of promoting the detergent solution can be omitted. That is, if the amount of clothing is relatively large, the mechanical force is not sufficient for clothes to come in sufficient contact with the wash water since the wash water cannot be supplied to / absorbed by the tangled clothes in a sufficient quantity.

As a result, if the amount of clothing is a predetermined or higher level, the stage of promoting the detergent solution is skipped and the clothes wetting stage is started immediately. If the amount of clothing is the predetermined or higher level, the clothing can make better contact with the wash water to promote detergent dissolution through the circulation stage in the water supply stage.

A.1.2.3 Wetting (S736) of clothing:

A stage of sufficiently wetting the laundry with the wash water can be implemented in the water supply stage, together with the detergent solution. In the case of a drum-type washing machine, the clothes do not have to be completely submerged in the washing water and, therefore, the wetting of the clothes can be quickly implemented at an initial stage of the washing cycle. After the stage of promoting detergent dissolution, a stage promoting the wetting of clothes can be implemented to promote the wetting of clothes. This stage can be implemented after the water supply stage is performed to a predetermined degree or until the water supply stage is completed to ensure that the clothing is sufficiently saturated. Alternatively, the step of promoting the detergent solution can be implemented after the supply water has been completed. The water level decreases at the stage of wetting clothes and an additional water supply can be implemented.

The clothes wetting stage can be partially implemented in which stage of promoting the detergent solution mentioned above and a water level can be increased sufficiently to allow the washing water to be collected inside the drum. Because of this, the stage of promoting the wetting of clothes can be implemented after the stage of promoting the detergent solution. A drum drive movement of the clothing wetting promotion stage can be controlled differently compared to that of the stage of promoting the detergent solution. For example, the drum drive movement of the clothing wetting promotion stage may include a turning movement and / or a filtration movement. In certain embodiments, the filtration movement and the rotation movement can be implemented sequentially.

The filtration movement is a movement in which the clothing is widely distributed to expand the surface area of the clothing, and therefore the filtration movement can be used to wet the clothes evenly. The turning movement is a movement in which the clothes are repeatedly tipped along to make the wash water stay under the drum in contact with the clothes in a uniform manner, and the turning movement can also be applied in the wetting clothes. To use these effects as much as possible, different drum drive movements, that is, repeated / sequential implementation of the filtration and rotation movements in a predetermined order can maximize the effect of the stage of promoting the wetting of clothes.

If the amount of clothing is at a predetermined level or higher, the drum drive movement of the clothing wetting promotion stage may include the filtration movement. That is, in the filtration movement, the surface area of the clothing is enlarged and the washing water is supplied in the movement of

5

10

fifteen

twenty

25

30

35

40

Four. Five

55

filtration, and the clothes are distributed evenly without getting tangled and the washing water is supplied to the clothes evenly. As an alternative, or in addition to the filtration movement, the flipping movement can also be implemented.

If the amount of clothing is below the predetermined level, a filtration and / or flipping movement can be used during the stage of promoting the wetting of clothes.

The user can select a level of contamination of the clothes in the selection part 118 of options and a net engine performance ratio can be differentiated according to this selection. However, the net performance ratio in the water supply stage cannot be differentiated according to the level of contamination selected, because the net performance ratio in the water supply stage is predetermined to optimize the detergent solution and the wetting of clothes, and due to the worry of unnecessary damage to clothes can not be ignored. If the net acting ratio is reduced, the detergent solution and the wetting of the clothes cannot be sufficiently implemented.

The water supply stage in the standard program may include the detergent type determination stage, the detergent dissolution dissolution stage and the clothing wetting promotion stage described above. In alternative embodiments, the stage of determining the type of detergent, the stage of promoting the detergent solution or the stage of wetting clothes can be provided regardless of the stage of water supply. In this case, the detergent determination stage, the stage of promoting the detergent dissolution or the laundry wetting stage can be implemented after the water supply is completed.

A.1.3 Heating (S740):

The wash cycle includes the wash stage. To prepare for washing, a heating stage can be implemented between the washing and water supply stages.

The heating stage can be configured to heat the wash water by using the heater provided in the tank or to increase the temperature of the washing water or the drum by using steam supplied inside the drum. Because of that, the heating stage can be implemented or omitted if necessary. That is, if air or cold water is used for the treatment of clothing, the heating stage may not be implemented. However, if the wash water temperature is preset to be higher than the cold water temperature because of a predetermined temperature associated with a selected program, or if the wash water temperature is selected to be higher than the temperature of the cold water of part 118 of option selection, the heating stage can be implemented.

The movement of the drum in the heating stage may vary depending on the quantity of the clothes. A flipping movement can be implemented in the heating stage regardless of the amount of clothing. However, as mentioned above, if the amount of clothing is at the predetermined or lower level, the turning movement can be implemented in the heating stage. That is, in case the clothes are relatively small, repeated turning of the clothes in the lower part of the drum can be more effective in heating and washing than in the distribution of the clothes. Alternatively, with a small amount of dirty clothes in the heating stage, a combination of the turning and turning movements can be used, and with a large amount of clothing, the turning movement can be used.

The heating stage may include a heating preparation stage configured to prepare for heating after the water supply stage. This means that the water supply stage is completed after the end of the wetting of the clothes. As a result, it is possible to determine the amount of clothing more precisely after the water supply stage, because wet clothes cannot be distinguished from dry clothes based on the amount of clothing before wetting the clothes. For example, the amount of wet clothes can be determined as greater than the actual amount, before wetting the clothes. As a result, in certain embodiments, a step of determining the most precise amount of clothing can be implemented in the heating stage, before washing. If the heating stage is omitted, a stage corresponding to the preparation heating stage can be implemented to determine the precise amount of clothing. That is, if the heating stage is omitted, the stage of determining the amount of precise clothing can be implemented before the washing stage after the water supply stage complements.

A.1.4 Washing (S742):

Once the water supply stage and the heating stage described above have been completed, the washing stage configured to wash the laundry can be implemented. A drum drive movement in the washing stage can be a combination of stages and / or turning and / or turning movements to apply a large mechanical force and move the clothes in various patterns to improve washing efficiency.

Alternatively, the drum drive movement in the washing stage can be a sequential combination of the filtration movement and the turning movement to continuously supply washing water to the

5

10

fifteen

twenty

25

30

35

40

Four. Five

55

clothes to improve the washing efficiency generated by the detergent as well as the washing efficiency generated by the mechanical force applied to the clothes.

As a result, the driving movement of the drum in the washing stage can be differentiated according to the amount of laundry, because the driving movement of the drum capable of generating an optimal washing effect can be different depending on the amount of laundry. The amount of clothing may be the amount of clothing determined before the water supply stage or in the heating stage. In the washing stage, the drum drive movement can be differentiated depending on the amount of laundry determined after the water supply stage.

If the amount of clothing is at a predetermined or higher level, the drum drive movement may include the filtration movement and / or the turning movement. If the washer is not equipped to circulate the wash water, only the flipping movement can be implemented. In the case of a large number of clothes, the wash water can be supplied to the clothes evenly and the mechanical force can be applied to the clothes simultaneously to improve the washing efficiency.

If the amount of clothing is at a predetermined or lower level, the drum drive movement may include a progressive movement and / or a rotation movement to improve washing efficiency as the clothes move in various patterns with the mechanical force applied to clothing. In certain embodiments, the flipping movement can also be implemented with the progressive movement and / or the turning movement.

As mentioned above, in the standard program, the drum drive movement in the water supply stage, the heating stage and the washing stage can be diversified and the efficiency of the washing cycle can be improved accordingly. In addition, the drum drive movement in each of the stages can be differentiated depending on the amount of laundry in the drum and the optimized washing cycle can be implemented accordingly.

If the user selects a level of contamination in the clothing of the option selection part 118, the net performance ratio of the heating stage and the washing stage can be differentiated. If the net performance ratio is unnecessarily high in a case where the level of contamination is relatively low, the clothing would be unnecessarily damaged.

A.2 Rinse cycle (S750):

A procedure for controlling a rinse cycle in program A will be described with reference to Figure 7. According to this embodiment, the rinse cycle can be implemented as part of a single program, together with the wash cycle described above. , or it can be implemented independently. Simply to facilitate the description, a rinse cycle control procedure implemented after the wash cycle mentioned in the standard program will be described below.

A.2.1. First rinse (S751):

Once the wash cycle has been completed, a first rinse stage configured to supply water and operate the drum to implement the rinse can be performed.

One or more centrifugation stages can be implemented in the standard program in each of the wash cycle, the rinse cycle and the spin cycle. For example, centrifugation after the wash cycle and centrifugation in the rinse cycle can be implemented. These spin stages can be referred to as 'intermediate spin' to distinguish from the spin cycle that is the last cycle of the standard program.

A spin level can be determined based on the RPM of the drum. Normally, intermediate spinning can be implemented at about 200 to 400 RPM, and, for example, at about 400 RPM in a sensitive program, at about 600 RPM in a weak program, at about 800 RPM in an intermediate program, and at about 1,000 RPM in a strong program. The drum RPM for intermediate spinning can be selected based on a low resonance frequency and a high resonance frequency during operation depending on the current operating parameters.

The resonant frequency is a physical value of the washing machine itself and the vibration of the washing machine increases dramatically near the resonant frequency. If the drum is rotated around the resonant frequency and the clothes are not distributed evenly, the vibration of the washing machine will increase very suddenly. As a result, if the spin is performed at a predetermined RPM higher than the resonant frequency, a clothing unraveling stage would normally be implemented to distribute the clothes evenly inside the drum and the vibration is detected. If the detected vibration is less than a predetermined value, an acceleration stage can be implemented to be outside a resonance frequency band.

Since the water supply and the rinse are repeated more times in the rinse cycle, the time required for intermediate spinning implemented in the middle of the rinse would be longer. To address the

Residual detergent concerns that remain after the wash is complete, the rinse steps can be implemented at least three times or more in the rinse cycle. The intermediate spin implemented at this time can add a significant amount of time to the rinse cycle, which results in an excessively long rinse cycle. According to this embodiment, the RPM in the intermediate centrifuge implemented in the medium of the water supply and the rinse can be differentiated. That is, the drum can be rotated at a predetermined RPM lower than the low resonance frequency in a specific predetermined intermediate spin and at a predetermined RPM greater than the high resonance frequency in another specific predetermined intermediate spin.

When the specific intermediate spin is run at a lower RPM than the low resonance frequency, the time required for an auxiliary clothing unraveling stage, vibration amount sensing stage and acceleration stage may be unnecessary, thereby potentially reducing the time required for the rinse cycle. The RPM of this intermediate centrifuge can be set to be approximately 100 to 110. On the contrary, if the specific intermediate centrifuge is run at a lower RPM than the low resonance frequency, the time required by the rinse cycle can be reduced. , but the washing water that includes the detergent cannot be completely discharged.

Most contaminants and detergent residues can be found in the wash water after the wash cycle. Because of that, the wash water can be discharged from the clothes as thoroughly as possible after the wash cycle.

A high speed spin (S752) can be implemented in an initial stage of the first rinse stage, after the wash cycle in the standard program. In high speed spinning, the drum can rotate at a higher RPM than the high resonant frequency so that a maximum amount of wash water can be discharged into clothing. For example, the RPM can be set at approximately 1000 RPM. The high speed spin stage can continuously rotate the drum at high speed, that is, approximately 1000 RPM, regardless of user selection, so that the detergent residue can be discharged as thoroughly as possible before rinsing.

Upon completion of high speed spinning, a first stage (S753) of drum operation can be implemented to drive the drum after water supply to rinse the laundry. A rinse water level can be a relatively high level allowing the water level to be visible through the door, whereby the clothes are submerged in the wash water. Therefore, a significant amount of wash water can be supplied to rinse clothes at an initial stage of the rinse cycle.

A drum drive movement in the first drum drive stage may be a rubbing and / or oscillation movement, to move the maximum amount of clothing immersed in the wash water to improve rinse performance. This rubbing and oscillation movements correspond to a procedure of continuously rubbing the clothes under the washing water after immersing the clothes in the washing water. The turning and progressive movements correspond to a procedure of repeatedly moving the clothes in and out of the wash water. As a result, the first drum drive stage can control the drum for use in rubbing and oscillation movements, with a high level of water, allowing the user to visually recognize the implementation of sufficient rinse. In alternative embodiments, a circulation stage configured to circulate the wash water contained in the tank in the drum can be implemented in the first stage of drum operation. The washing water is sprayed in the drum to wash the clothes. This procedure can be referred to as 'spray rinse'. This also shows a user, as it can be visible through the door, which is sufficiently enlightened implemented.

Once the first drum drive stage has been completed, a first stage (S754) of intermediate drain and spin can be implemented. During the discharge of the water, the drum can be operated in the progressive and / or flipping movement. Clothes are raised and lowered to improve washing efficiency and bubbles are generated to improve rinse efficiency. The movement of the drum can be differentiated depending on the quantity of clothes. In the case of a small amount of clothing, the drum is operated in the progressive movement to generate the maximum distance between the elevation and the fall. In the case of a large amount of clothing, the drum can be operated in the flipping motion.

Intermediate centrifugation can be implemented at approximately 100 to 110 RPM in the first drain and intermediate centrifuge. Then, the clothing unraveling stage, the vibration detection stage and the acceleration stage can be omitted and the time required can be significantly reduced.

In alternative embodiments, in the first stage of intermediate drain and spin of a standard program, the intermediate spin can be implemented at approximately 400 RPM higher than the low resonance frequency. In this case, progressive and / or flipping movement can be implemented when water is drained and clothing is sufficiently distributed. Because of that, the unraveling stage of clothing can be omitted. Even at a higher rotation speed than the low resonance frequency, intermediate spinning can be implemented for a short time, with the vibration detection stage and the individual acceleration stage. Such intermediate centrifugation can be implemented at a relatively high RPM to discharge the remains of

detergent and contaminants that fail to be discharged through the high speed spin stage. However, in a case where the amount of vibration measured in the vibration detection stage is outside an allowable range, the vibration detection stage can be repeated to stop entering the acceleration stage, and the time Washing could be increased disadvantageously. Because of that, the vibration detection stage can be implemented at the drum speed of about 100 to 110 RPM and, in case the acceleration stage does not start within a predetermined time of vibration stage implementations, The first stage of drain and intermediate centrifugation can end.

A.2.2 Second rinse (S756) and final rinse (S760):

A second stage (S756) of rinse may follow the first stage of rinse. The second rinse stage may include a second stage (S757) of drum operation and a second stage (S758) of intermediate drain and spin. The second drum drive stage may be essentially the same as the first drum drive stage described above. In addition, the second drain stage and intermediate spin may be essentially the same as the first drain and intermediate spin stage. However, the intermediate spin is performed at approximately 100 to 110 RPM in the second drain stage and intermediate spin to reduce the washing time, because the detergent remains have already been discharged in the high speed spin stage and in the First stage of drain and intermediate spin.

The rinse cycle can make use of the result of the determination of the step of determining the type of detergent.

If the detergent is of the liquid type, relatively little detergent can remain and the second rinse stage can be omitted to reduce the time required for the rinse cycle. If the detergent is a powder type, the first rinse stage and the second rinse stage can be performed by default.

If the detergent is of the liquid type, a third stage (S760) of washing may serve as a final rinse stage after the first rinse stage. If the detergent is a powder type, the third rinse stage can serve as a final rinse stage after the second rinse stage. However, when the bubbles are detected in the third washing stage (in the case of a powder type detergent), a fourth rinse stage such as the final rinse stage can be implemented.

A water level of the final rinse stage (S760) may be a relatively low level. In the case of an inclined drum type washing machine having an inclined drum at a predetermined angle, a water level may be a predetermined level sufficient to supply water only to a predetermined rear portion of the inclined drum. That is, the water level may be such that it is not detected, or is visible, from outside the washing machine. However, a water level of this type is predetermined so as not to generate more bubbles in the clothes. Even if bubbles are generated, bubbles are generated in the tank, not in the drum, to avoid excess accumulation. As a result, the user can visually identify that there are no bubbles generated in the final rinse stage and the satisfaction of the rinse performance can be improved.

A third stage (S762) of drainage can be implemented after the third stage (S761) of drum operation in the final rinse stage, to implement the spin cycle. The drum can be operated in the progressive and / or rubbing movement to distribute the clothes evenly in the third drainage stage.

A.3 Spin cycle (S770):

A spin cycle control procedure in the standard program will be described with reference to Figure 7. The spin cycle can be implemented as a part of the standard program, together with the wash cycle and rinse cycle, or independently as A single program. Simply to facilitate the description, a centrifugal cycle control procedure implemented after the wash cycle and the rinse cycle that make up the standard program will be described.

A.3.1 Unraveling (S771) of clothing:

The spin cycle may include a clothes unraveling stage configured to unravel the clothes by actuating the drum to distribute the clothes evenly. The spin cycle is provided to minimize the vibration generated when the drum is rotated at a high speed. If the drum is operated in the progressive and / or rubbing movement in the drainage stage just before the spin cycle, it is likely that the clothes will be unraveled to a predetermined degree by the progressive and / or rubbing movement and the time required for the unraveling stage of clothing can be reduced significantly.

A.3.2 Measurement (S773) of eccentricity:

After the unraveling stage of clothing, the amount of eccentricity with the rotation of the drum at an RPM

predetermined lower than the low resonance frequency for a predetermined period of time, it can be measured by accelerating the drum and determining whether the clothes are distributed evenly inside the drum.

An eccentricity measurement stage of a spin cycle in a standard program according to another embodiment can be implemented before a clothing unraveling stage. A significant amount of unraveling of clothes may have been implemented by the drum drive movement of the rinse cycle. As a result, the spin cycle can begin with the eccentricity measurement step to reduce the spin cycle time. If the measured eccentricity compared to a reference eccentricity value is determined to be satisfactory, the acceleration, which will be described later, can be implemented. If the measured eccentricity is unsatisfactory compared to the reference eccentricity value, the unraveling stage of clothing can be implemented. The drum can be actuated in the progressive movement in the unraveling stage of clothes to promote the unraveling of the clothes and the eccentricity measurement stage can be restarted after the unraveling stage of clothes.

A. 3.3 Acceleration and centrifugation (S775) normal:

After the eccentricity measurement stage, a stage of acceleration of the drum rotation at a normal spin speed (acceleration stage) can be implemented. After that, a normal spin stage configured to rotate the drum at a normal spin RPM can be implemented to complete the spin cycle. The speed of rotation of the drum in normal spin can be preset to be approximately 1000 RPM. That is, the amount of moisture contained in the clothing can be reduced as much as possible to minimize detergent residue. The RPM of the normal spin may vary according to the user's selection, because the RPM of the normal spin is related to a residual moisture level and wrinkle level in the clothes after completing the spin cycle. As a result, the user can select an RPM of the normal spin stage, related to a humidity level and a wrinkle level of the clothing.

B. Program B (strong pollutants program):

A program B of strong contaminants in which a lot of dirt has to be removed from the garments will be described. Referring to Figure 8. The program of strong contaminants can be selected in part 117 of the program selection (S810).

B.1 Washing cycle (S830):

B.1.1. Determination (S831) of the amount of clothing:

Once the heavy pollutant program is selected, a step of determining the amount of clothes can be implemented to determine the amount of clothes loaded in the drum. The procedure for determining the amount of clothing may be similar to that described above with respect to the standard program, and therefore a repeated description thereof will be omitted accordingly. The stage for determining the amount of clothing could be implemented before the program selection stage.

The control part compares the amount of clothes determined in the step of determining the amount of clothes with a reference value and controls the drum drive movements of a water supply stage and a washing stage, which will be described more forward, based on the result of the comparison. Essentially, a certain amount of clothing greater than a reference value can be considered a large load, and a certain quantity of clothing less than the reference value can be considered a small load. The drum drive movements of each stage according to the amount of clothing determined will be described.

B.1.2 Water supply (S833):

In a water supply stage, the control part controls the water supply device (for example, the water supply path and the water supply valve) connected to the water supply source and to the tank to supply the wash water to the tank. If the amount of clothing that is measured in the step of determining the amount of clothing is less than a reference value, the control part may control the drum to actuate in the turning movement and / or the progressive movement and / or rubbing movement and / or filtration movement and / or turning movement.

First, if the clothes loaded in the drum become entangled, the eccentric rotation of the drum would be generated, and the control part can control the drum to actuate in the turning movement in the water supply stage to unravel the clothes. In the turning movement, the drum is rotated in a predetermined direction and the clothes are dropped to the lowest point of the drum from a position of approximately 90 ° or more with respect to the direction of rotation of the drum, so that tangled clothing can be unraveled and distributed evenly.

The control part controls the drum to rotate in the progressive movement and / or the rubbing movement so that a fall impact is applied to the clothes loaded on the drum. Progressive movement and rubbing can be applied to eliminate insoluble contaminants without problems. As a result, once the drum is actuated in the progressive movement and / or the rubbing movement, insoluble contaminants can be eliminated in the water supply stage, and a reduction of the washing time and an improvement of the washing efficiency

The water supply stage supplies water for washing water to the tank and moisturizes the laundry loaded in the drum, as mentioned above. Because of that, the control part can drive the drum in the filtration movement after the progressive movement and / or rubbing movement to wet the clothes.

In addition, the control part can drive the drum in the turning movement to dissolve the detergent in the washing water in the water supply stage, in addition to the turning movement, to moisten the laundry in the washing water, before complete the water supply stage.

If the amount of clothing is more than a reference value, the control part can control the drum to actuate in the turning movement and / or filtration movement, in the water supply stage. If the amount of clothing is relatively large, specifically, greater than the reference value, the movement of the drum configured to apply a sudden brake to the drum such as the progressive movement and / or the rubbing movement may apply too much load on the motor. By extension, the original effect of the progressive and / or rubbing movement that is the application of the fall impact cannot be achieved. Therefore, progressive and / or rubbing movement is not implemented if a large amount of clothing is loaded into the drum. In addition, if a large amount of clothing is loaded into the drum, the wetting effect of the clothing generated by the turning movement having a relatively low spin speed cannot be achieved effectively, and so it can be implemented instead. the flipping movement for wetting clothes. Eventually, if the amount of clothing is more than the reference value, the drum can be actuated in the turning and / or filtration movement in such a way that the effects of the washing distribution, the removal of insoluble contaminants, the wetting of the laundry and the detergent solution mentioned above can be achieved.

B.1.3 Washing (S835):

After the water supply stage is completed, a washing stage of the heavy contaminant program can begin. The washing stage of the heavy pollutants program may include a soaking stage, a contaminant removal stage and a removal stage for the remaining contaminants. In this case, wash water with different temperatures can be supplied at each stage and each stage can be implemented accordingly.

B.1.3.1 Soak (S836):

The soaking stage is a procedure of soaking the clothes in cold water to loosen the strong contaminants contained in the clothes. Relatively cold water having a temperature of, for example, approximately 15 ° C is used in the soaking stage, to loosen the protein components contained in the strong contaminants attached to the clothing for a long time. If these protein components come into contact with hot water, these strong contaminants tend to solidify permanently in clothing and it is difficult to separate them from clothing. Because of that, the soaking stage can be implemented using cold water, to prevent strong contaminants that have protein components from attaching to clothing.

If the amount of clothing is less than a predetermined value, the motor can drive the drum in the progressive movement. The turning movement and / or the turning movement can be added after the progressive movement. Since the progressive movement has excellent washing capacity and reduces the washing time, the strong contaminants attached to the clothing can be soaked and an impact is applied to the clothing. As a result, progressive movement has the effect of inducing the separation of strong contaminants from clothing.

If the amount of clothing is greater than the reference value, the drum can be operated in the turning movement and / or the turning movement in the soaking stage. That is, if the amount of clothing measured is greater than a predetermined reference value, progressive movement cannot be implemented due to the excessive load applied to the engine. As noted above, the progressive movement applies a fall impact to the clothes contained in the drum and improves the washing efficiency. However, if the amount of clothing is large, the progressive movement cannot be implemented. When the amount of clothing is greater than the reference value, progressive movement is also not implemented in the stages of contaminant removal and removal of the remaining contaminants, which will be described below.

B. 1.3.2 Elimination (S837) of contaminants:

After the soaking stage, a contaminant removal stage configured to heat the wash water in a range of 35 ° C to 40 ° C to remove the strong contaminants can begin. The temperature of the washing water used in the pollutant removal stage is set between 35 ° C and 40 ° C since

5

The sebum components contained in the strong contaminants can be more easily removed at a temperature that is similar to the temperature of the human body. The heater provided on the bottom surface of the tank or the moisture supply device configured to supply hot moisture, such as steam to the tank, can be used to increase the temperature of the wash water to within the predetermined range.

In the pollutant removal stage, the control part can control the engine to drive the drum in the turning movement and / or the turning movement if the amount of clothing is the reference value or less. The turning movement and / or the turning movement can be applied under load on the motor and reduce the washing time, with high washing efficiency. Because of that, a reduction in washing time can be achieved.

If the amount of clothing is more than the reference value, the control part can control the drum to actuate in the flipping movement. In the case of a large amount of clothing, the turning movement configured to rotate the drum at relatively low speed cannot be effective in removing contaminants, and therefore the turning movement can be applied.

B.1.3.3 Elimination (S838) of the remaining contaminants:

The control part can implement a pollutant removal stage configured to heat the wash water to have the temperature of approximately 60 ° C and sterilize and bleach the clothes, after the pollutant removal stage. The temperature of the wash water may be approximately 60 ° C or higher at the stage of removing the remaining contaminants to sterilize and bleach the laundry.

In the stage of elimination of the remaining contaminants, the control part can control the drum to actuate in the progressive movement or in the order of the progressive movement and / or turning movement and / or turning movement, if the amount of clothing is less than the reference value.

If the amount of clothing is greater than the reference value, the control part can control the drum to actuate in the filtration movement and / or turning movement in the stage of elimination of the remaining contaminants.

B.2 Rinse cycle (S850):

The rinse cycle of the heavy contaminant program may be similar to the rinse cycle of the standard program described above and the rinse cycles of the other programs that will be described later. Therefore, the repeated description of the rinse cycle will be omitted.

B. 3. Spin cycle (S870):

The spin cycle of the heavy contaminant program may be similar to the spin cycle of the standard program described above and the spin cycles of the other programs that will be described later. Therefore, the repeated description of the spin cycle will be omitted.

C. Program C (rapid boil program):

Program C will be described with reference to Figure 9. Program C may be referred to as the "rapid boil program" configured to heat the wash water at a predetermined temperature for a relatively short time to achieve a sanitary boiling effect of the clothing. , such as in a disinfection cycle.

Normally, when the clothes are sterilized and bleached, the wash water contained in the tank is heated to a preset 'setpoint temperature' and then the washing is implemented. Since the washing time is relatively long and the electrical power consumed is enough to heat the washing water only, it takes quite a long time and a lot of electrical energy to heat the washing water contained in the tank to the preset temperature. In the rapid boil program the clothes can be sterilized and bleached while also reducing the total washing time and energy consumption. The rapid boil program heats the washing water supplied to the drum for a predetermined period of time, regardless of the temperature of the washing water, instead of heating the washing water until the washing water reaches the preset temperature. In order to have the washing capacity under consideration, a stage of compensating the moment of a washing stage provided in the rapid boiling program according to the temperature of the washing water can be included in this washing cycle, as will be described with reference to Figure 9.

First, the user can select the rapid boil program in the program selection part 117 (S910). Next, the control part implements a time setting stage of the wash stage of the rapid boil program. This stage of setting the washing time allows the control part to determine the time required by the washing stage of the rapid boiling program, which is stored in a storage device, such as a memory. This stage can be implemented simultaneously with the program selection stage or a water supply stage.

C.1 Washing cycle (S930):

C.1.1 Determination (S931) of the amount of laundry and setting of the washing time:

Once the user selects the rapid boil program, the control part can implement a step of determining the amount of clothes configured to measure the amount of clothes and a stage of setting the washing time configured to adjust the required time for a washing stage of the rapid boil program based on the amount of clothing determined. The control part may use the time necessary to rotate the drum to a predetermined position to determine the amount of clothing, as described above, or the residual rotation time after the drum is rotated for a predetermined time.

In the stage of setting the wash time, the control part can select a wash time corresponding to the amount of clothing measured from the appropriate times stored in the memory. The variety of time required by the wash stage of the rapid boil program is stored in the storage device, such as memory, so that, when the rapid boil program is selected, a suitable time stored in the memory can be select by the control part.

C.1.2 Water supply (S933):

The wash cycle of the rapid boil program may include a water supply stage configured to supply wash water to the tank. In the water supply stage, the control part controls the water supply device (for example, water supply path and water supply valve) connected to the water supply source and the water supply tank to Cuba. In addition, the control part controls the drum to be operated in a drum drive movement similar to the drum drive movement of the water supply stage of, for example, the heavy pollutant program described above, and therefore a description more detailed will be omitted.

C.1.3 Stage (S935) of water temperature / compensation measurement:

Once the water is supplied to the tank, the control part measures the temperature of the washing water using a temperature sensor provided in the washing machine and compares the measured temperature with a reference temperature to adjust the stage time washing

For example, the control part may compare the measured temperature of the wash water with a reference temperature, for example, greater than about 50 ° C. If the measured temperature is higher than the reference temperature, for example, if hot water is supplied to the tank, the control part can implement the washing step immediately. However, if the measured temperature is lower than the reference temperature, the control part may implement a compensation stage configured to adjust the washing stage time.

As mentioned above, the washing step can be implemented after heating the washing water for the predetermined period of time in this program, regardless of the water temperature. Because of that, the temperature of the wash water contained in the tank may be different, depending on the temperature of the water supplied to the tank after a heating stage has been completed, and there would be no difference in the washing capacity due to to the difference of the water temperature. As a result, the compensation stage is provided to minimize the difference in the washing capacity caused by the washing water with different temperatures after the heating stage. If the washing water temperature is lower than the reference temperature, the washing stage time is increased to compensate the washing capacity at the lower temperature.

The number of reference temperatures used to define a temperature range can be adjusted appropriately. For example, in one embodiment, a single reference temperature may be provided, and in alternative embodiments, a plurality of the reference temperatures may be provided. When the temperature of the wash water is higher than a first reference temperature (for example, 50 ° C) and there are three reference temperatures, that is, first, the second and third reference temperatures are provided, the control part can Implement the wash stage immediately. When the measured temperature of the wash water is lower than the first reference temperature and higher than the second reference temperature, the second reference temperature (for example, 40 ° C) which is lower than the first reference temperature (for example 50 ° C), when the measured temperature is lower than the second reference temperature and higher than the third reference temperature, the third reference temperature (for example, 30 ° C) is lower than the second reference temperature (for example , 40 ° C) and when the measured temperature is lower than the third reference temperature, the compensation stage configured to compensate for the time of the preset washing stage in the washing time adjustment stage is performed.

When the washing stage time is compensated, the control part can control the compensated time to be different depending on the temperature of the washing water. The washing capacity is substantially in relation to the temperature of the washing water. Because of this, the lower the measured temperature of the wash water, the longer the compensated time will be. The reference temperature and the time interval added in the

Compensation stage can be preset based on the capacity of the washing machine and other similar factors.

C.1.4 Heating (S937):

Once the predetermined time of the washing stage is compensated in the compensation stage, a heating stage configured to remove the contaminants contained in the clothes by means of the drum movement and heating the washing water at the same time can be implemented. for a predetermined period of time. The heating stage can be implemented as an independent stage or as part of a washing stage which will be described later. Simply to facilitate the description, in this description of the program, the heating stage is described as the part of the washing stage.

C.1.5 Washing (S939):

A drum drive movement of the washing stage of the rapid boiling program may include the progressive movement and / or the turning movement and / or the turning movement.

The progressive movement has excellent washing capacity and applies the impact to the clothes in such a way that the contaminants attached to the clothes can be separated and the washing time can be reduced. As a result, the control part can rotate the drum in the progressive movement at an initial stage of the washing stage. In this case, the heating stage can be implemented after the progressive movement of the washing stage.

In progressive movement, the drum is rotated at a predetermined speed allowing the clothes not to fall from the inner circumferential surface of the drum due to centrifugal force. When the clothes are near the highest point of the drum, a reverse pair is applied to the drum. Since the net operating ratio of the progressive movement is adjusted, the load applied to the motor is larger in the progressive movement than in the other movements. Because, if the heating stage configured to heat the wash water is continued during the progressive movement, the energy consumption would increase and a safety problem could occur due to the increase in the amount of current. As a result, the heating stage can be implemented for a predetermined time after the progressive movement is completed.

The heating stage is configured such that the heater is not activated for a predetermined period of heating time, and not necessarily until the temperature of the wash water reaches the preset value. This allows the time and electrical energy required by the washing stage to be accurately forecast and the user is notified of the predicted data. In addition, the washing stage can be implemented only for essentially the same preset time, regardless of the temperature of the washing water supplied in the washing stage, so that energy consumption and washing time can be reduced.

Therefore, the control part can control the turning movement and / or the turning movement to be implemented. In this case, the turning movement and / or the turning movement can be implemented simultaneously with the start of the heating stage. The turning movement and the turning movement apply a low load to the motor and have good washing capacity, with a reduced washing time. As a result, the turning movement and the turning movement can achieve the effect of reducing the washing time required by the washing stage and the effect of an adequate washing capacity even with the washing stage implemented using the washing water with Different temperatures

C.2 Washing cycle (S950):

A rinse cycle of the rapid boil program may be similar to the rinse cycles of the programs described above and the rinse cycles of other programs which will be described later. Therefore, an additional detailed description thereof will be omitted.

C. 3 Cycle (S970) spin:

A spin cycle of the rapid boil program may be similar to the spin cycles of the programs described above and the spin cycles of the other programs that will be described later. Therefore, an additional detailed description thereof will be omitted.

D. Program D (cold wash program):

A cold wash program D will be described with reference to Figure 10. The cold wash program D is configured to wash clothes without heating the wash water, providing energy savings, without degrading the desired washing capacity. As a result, this program measures the temperature of the wash water supplied to the tank, the measured temperature is compared with a preset temperature, and the operating parameters are adjusted accordingly, which allows the washing capacity to be maintained. For example, if the wash water temperature does not reach a reference temperature based on the result of the comparison, the wash time is sufficiently compensated to provide a target wash capacity in the wash program.

First, the user can select the cold wash program in the program selection part 117 (S1010). Once the user selects the cold wash program, the control part can implement a wash cycle, a rinse cycle and / or a sequential or selectively spin cycle.

5 D.1 Washing cycle (S1030) (first embodiment):

D.1. Determination (S1031) of the amount of laundry / setting of the washing time:

Once the user selects the cold wash program, the control part can implement a step of determining the amount of clothes configured to measure the amount of clothes and a stage of setting the washing time configured to adjust the time required by a washing step of the cold wash program 10 based on the measured amount of clothing. In the step of determining the amount of clothing, the control part may use the time necessary to rotate the drum to a predetermined position or the residual rotation time of the drum, to measure the amount of clothing, as has been previously described. In the stage of setting the washing time, the control part may select a washing time corresponding to the amount of clothing measured from appropriate times stored in the memory according to the amount of clothes.

D.1.2 Water supply (S1033):

The wash cycle of the cold wash program may include a water supply stage configured to supply wash water to the tank. In the water supply stage, the control part controls the water supply device (for example, water supply path and water supply valve) connected 20 with the water supply source and the tank to supply water to the tank In addition, the control part controls the drum to be operated in a drum drive movement similar to the drum drive movement of the water supply stage of the heavy contaminant program or the rapid boil program described above. Therefore, an additional detailed description thereof will be omitted.

D.1.3 Measurement (S1035) of water temperature / compensation of washing time:

25 Once the wash water is supplied to the tank, the control part can measure the temperature of the wash water using a temperature measuring device provided in the washing machine. The control part can compare the measured temperature with a reference temperature (for example 15 ° C). If the measured temperature of the wash water is the reference temperature or more, the control part can implement the washing step without compensating the washing time according to the amount of laundry. If the measured temperature is lower than the reference temperature, the control part can implement the washing time compensation stage. In this example, the temperature of '15 ° C 'is presented as an example of a critical temperature capable of ensuring a cold wash wash capacity and a reference temperature of a wash capacity test using cold water. As a result, if the measured temperature of the wash water is lower than the reference temperature, the control part can adjust the time of the washing stage 35 set in the washing time setting stage. For example, if the measured temperature is lower than the reference temperature, the control part may add a predetermined time to the washing stage time to avoid deterioration of the washing capacity due to the use of cold washing water having a temperature lower than the reference value. For example, if the measured temperature of the wash water is less than about 10 ° C, 10 minutes can be added to the time of the washing stage in the step of clearing the washing time. If, for example, the measured temperature is more than 10 ° C and less than 15 ° C, 5 minutes may be added at the time of the washing step.

D.1.4 Washing (S1037):

Once the time of the washing stage is compensated, the amount of clothing measured in the stage of determining the amount of clothing mentioned above is compared with a clothing quantity value of 45 reference and a washing stage that includes Different drum drive movements implemented according to the amount of clothing, can be implemented. The amount of reference clothing quantity can be preset based on a quantity of clothing that allows progressive movement, taking into account the size of the drum and the motor output. For example, the reference value of the amount of laundry can be an average value of the washing capacity of the washing machine (approximately 5 ~ 6 kg in a 50 washing machine having a capacity of 11 kg). A case in which the value of the amount of clothing measured is less than the value of the quantity of reference clothing will be described first, and then a case will be described in which the measured value is the reference value or more.

When the value of the quantity of clothing measured is less than the value of the quantity of reference clothing, the control part controls the progressive movement and / or the turning movement and / or the turning movement to be implemented in the washing step 55. The progressive movement applies the impact of falling to the clothes loaded on the drum and the contaminants contained in the clothes can be easily removed, even if cold water is used. If the clothes become entangled during the washing stage, the eccentric rotation of the drum can be generated. Therefore, the control part drives the drum

in the turning and / or turning movement to unravel and distribute the tangled clothing.

When the measured quantity of clothing is the reference value or more, the control part controls the filtration movement and / or the turning movement to be implemented in the washing stage. If the amount of clothing is the reference value or more, the large amount of cargo makes it difficult to achieve the effect of applying the impact of the clothing on the progressive movement and the effect of spinning the clothes along the inner circumferential surface of the drum in the turning movement. Because of that, the filtration movement and the flipping movement can be implemented, individually or sequentially, to achieve the effect of ensuring the washing capacity and the distribution effect of the clothing.

D.1 'Washing cycle (S1130) (second embodiment):

Figure 11 is a diagram of a cold wash program according to a second embodiment as described herein extensively.

In comparison to the cold wash program according to the first embodiment, the cold wash program according to the second embodiment omits a washing time setting stage and a compensation stage and instead the water is heated wash using the heater if the wash water temperature is below 15 ° C. That is, in a wash cycle according to the second embodiment, the amount of clothing is determined (S1131) and a water supply stage (S1133) can be implemented immediately without adjusting the washing time. After that, the temperature of the wash water is measured (S1135) to implement the wash stage (S1137). A drum drum drive movement can be differentiated depending on the amount of laundry in the washing step according to the second embodiment, which is similar to the first embodiment described above.

A case in which the amount of clothing measured in the washing step is less than the reference value will be described, in which the drum drum drive movement includes the progressive movement and / or turning movement and / or movement of turn.

When the measured temperature of the wash water is lower than the reference value, the progressive movement is performed after the washing stage begins. After the progressive movement, a heating stage configured to heat the wash water using a heater or a moisture supply device provided in the tank can be implemented. The warm-up stage begins after the progressive movement, because the progressive movement applies an increase in motor load, as mentioned above. Therefore, a safety problem, as well as the deterioration of the washing capacity can occur if the heating stage and the progressive movement are implemented simultaneously. In addition, if the heating stage is carried out before the progressive movement to avoid the above problems, the washing time would be disadvantageously increased. Therefore, in this embodiment the heating stage begins after the progressive movement is completed.

At the time of starting the heating stage, the control part can implement the turning movement and, sequentially, the turning movement. The turning movement and the turning movement have no concern in the deterioration of the washing capacity or safety and can reduce the washing time, even if they are applied together with the heating stage simultaneously.

The wash water temperature is measured again after the heating stage and it is determined whether the newly measured temperature reaches the reference temperature. When the wash water temperature reaches the reference temperature, the heating stage may end. However, if the washing water temperature does not reach the reference temperature, the heating stage can be continued during the washing stage. That is, even if the temperature of the washing water heated in the heating stage does not reach the reference temperature, if the washing stage ends then the heating stage also ends.

If the measured temperature is the reference temperature or more, the control part drives the drum in the progressive movement and / or the turning movement and / or the turning movement essentially the same as in the description of the driving movement of the drum of according to the first embodiment, and therefore an additional description thereof will be omitted accordingly.

If the amount of clothing is the reference value or more in the washing stage, the control part can operate the drum in the filtration movement and / or the turning movement. At this time, the heating stage can be provided in case the measured temperature of the wash water is lower than the reference temperature. As described above, the drum is not actuated in the progressive movement during the heating stage.

In comparison to the cold wash program according to the first embodiment described above, the cold wash program according to the third embodiment supplies hot water to the tank if the temperature of the wash water supplied in a supply stage of Water is less than about 15 ° C. That is, after determining (S1231) the amount of clothing, the control part can implement a water supply stage (S1233) configured to supply wash water to the tank based on the amount of clothing determined, omitting a time configuration of the washing time and a compensation stage.

At the time of application of the water supply stage, the control part supplies cold water to the tank (1234) and can also implement a stage (S1235) for measuring the temperature of the water and the cold water is supplies simultaneously. In this case, when the measured temperature of the wash water is 15 ° C or higher, a washing step (S1240) can be implemented according to the amount of the laundry loaded in the drum. If the measured temperature is below 15 ° C, a stage (S1236) of hot water supply can be implemented.

The water supply stage can be continued until the amount of cold water and the amount of hot water supplied in the water supply stage reaches the amount of wash water determined according to the amount of clothing. Once the water supply stage is completed, a washing stage implemented according to the amount of clothing can begin. The driving movement of the drum can be differentiated according to the amount of laundry in the washing stage, just like the first embodiment described above, and therefore a more detailed description thereof will be omitted.

D.2 Cycle (S1050, S1150, S1250) rinse:

A rinse cycle of the cold wash program may be similar to the rinse cycles of the programs described above and the rinse cycles of the other programs that will be described later. As a result, an additional detailed description thereof will be omitted.

D. 3 Cycle (S1070, S1170, S1270) spin:

A spin cycle of the cold wash program may be similar to the spin cycles of the programs described above and the spin cycles of the other programs that will be described later. As a result, an additional detailed description thereof will be omitted.

E. Program E (color garment program):

Program E will be described Referring to Figure 13. Program E can be referred to as a 'color garment program' configured to wash color wash items more efficiently. When washing color wash items, a problem of color migration, which can cause the color to pass between the color elements, discoloration, a lint problem and a ball formation problem can occur. The migration of the previous color is likely to be generated since the static friction between the drum and the clothing is greater. This program may include a temperature control stage configured to prevent color migration by controlling the temperature of the wash water, a color article washing stage configured to operate the drum to prevent the formation of lint and pellets. , and a rinsing stage. As follows, the steps will be described in detail.

E.1 Washing cycle (S1330) (first embodiment):

E.1.1 Water supply (S1331):

In a water supply stage, the control part controls the cold water to be supplied to the tank. Color migration is more likely to occur at a higher wash water temperature. In the water supply stage, the control part can control the motor to drive the drum in the oscillation movement or the filtration movement or a combination thereof. The water supply stage can be provided to supply wash water necessary to wash the laundry in the tank and to moisten the laundry loaded in the drum in the wash water. As a result, the drum is actuated in the filtration movement in the water supply stage such that the wetting of the clothes can be implemented effectively. In addition, the drum can be operated in the oscillation movement in the water supply stage, rather than in the filtration movement. The oscillation movement can minimize the movement of the clothes inside the drum, in comparison with the other movements, to minimize the generation of lint and the formation of balls that could be generated by the frictional force between the laundry articles.

E.1.2 Stage (S1333) for measuring water / heating temperature:

Once the water supply stage is completed, the control part can measure the temperature of the wash water supplied to the tank. When the measured temperature is a reference temperature or more (for example 30 ° C or 40 ° C), the control part can start the washing step immediately. When the measured temperature is lower than the reference temperature (for example, cold water because the washing water supplied in the water supply stage is cold water), the control part can initiate a configured heating stage

to heat the wash water. In certain embodiments, the temperature (reference temperature) of the wash water that allows the washing stage to begin can be set to be 30 ° C or 40 ° C, since the temperature of the wash water capable of maximizing the washing capacity , while minimizing color migration is in a range of 30 ° C to 40 ° C.

The heating stage heats the washing water supplied to the drum using a heater provided on the bottom surface of the tank or a steam generating device configured to supply steam to the tank.

E.1.3 Washing (S1335):

When the heating stage allows the washing water temperature to reach the reference temperature (30 ° C or 40 ° C), the control part can initiate a washing stage. In the washing stage, the control part can control the drum to be operated in a drum driving movement that can minimize the force of mechanical friction to prevent the formation of lint and balls and achieve the desired washing capacity. For example, the control part can control the drum to actuate in the oscillation movement and / or the progressive movement, in the washing stage of this program. Such progressive movement and oscillation movement can be implemented sequentially and the sequential application can be repeated.

The oscillating movement rotates the drum in both opposite directions and drops the clothes from a position of approximately 90 ° or less with respect to the direction of rotation of the drum. The oscillation movement applies rheostatic braking to the motor, because the physical friction applied to the clothing can be reduced as much as possible, while maintaining a predetermined level of washing efficiency. As a result, the possibility of lint and pellet formation, which can be generated by friction between the clothes or between the clothes and the drum, can be minimized.

As mentioned above, the progressive movement rotates the drum at the predetermined speed allowing the clothes not to fall from the inner circumferential surface of the drum by centrifugal force and then apply the sudden brake to the drum to maximize the impact applied to the clothes . Because of that, the progressive movement has excellent washing capacity, and is sufficient to compensate for an insufficient washing capacity of the oscillating movement. The period of time during which the progressive movement is performed may be shorter than the period of time during which the oscillation movement is performed to minimize the possibility of lint and ball formation.

E.1 'Washing cycle (S1430) (second embodiment):

Figure 14 is a diagram of a color garment program according to a second embodiment. Unlike the previous program according to the first embodiment, the color garment program according to the second embodiment allows a water temperature measurement stage and a heating stage to be applied in a washing stage (S1433) after a water supply stage (S1431). If the water temperature measurement stage and the heating stage are implemented before the washing stage, the washing time would be disadvantageously increased. As a result, this embodiment presents a program of colored garments capable of reducing the washing time compared to the previous embodiment.

After the water supply stage (S1431), the control part can control the drum to actuate in the progressive movement and / or oscillation movement in the washing stage and can determine if the temperature of the washing water is a temperature reference (for example, 30 ° C or 40 ° C) or more at the same time. When the temperature of the wash water is the reference temperature or more based on the result of the determination, the control part controls the drum to be operated continuously according to the washing step. When the temperature of the wash water is lower than the reference temperature, the control part can initiate a heating stage configured to heat the wash water.

The control part can control the drum to actuate in the progressive movement in the heating stage. That is, in the heating stage, the control part drives the drum in the oscillating movement, not in the progressive movement. The reason why this heating stage is not implemented together with the progressive movement simultaneously is described in the previous programs and thus a more detailed explanation will be omitted.

E.2 Rinse cycle (S1450):

The control part may start a rinse cycle after the wash cycle is completed. The control part can control the drum to actuate in the filtration movement during the rinse cycle. The filtration movement rotates the drum at the predetermined speed that allows the clothes not to fall from the inner circumferential surface of the drum by centrifugal force and then spray the washing water into the drum such that the filtration movement can be apply to moisten or wash clothes. In addition, the filtration movement can generate little friction between the clothes and between the clothes and the drum. Because of that, the filtration movement allows the clothes to clear up in a relatively short time. The control part can implement the turning movement in the rinse cycle to complement the rinse capacity of the filtration movement.

E. 3 Cycle (S1470) spin:

Once the rinse cycle is complete, a spin cycle configured to remove the laundry water from the clothes can begin. The spin cycle of the color garment program may be similar to the spin cycles of the programs described above and the spin cycles of the other programs described below and therefore a further detailed description thereof will be omitted.

F. Program F (functional garments program)

The F program will be described Referring to Figure 15. The F program can be referred to as a functional garment program 'configured to wash functional garments, including sports garments such as mountaineering garments and other sports garments, effectively, without damaging the cloth Functional garments are manufactured to be appropriate for outdoor activities such as mountaineering, swimming, cycling and the like. Functional garments absorb sweat quickly and discharge moisture absorbed outdoors, and help maintain body heat. However, these functional garments are made of fine synthetic fabric and are more fragile than other types of fabrics. A washing program for functional garments can be optimized to be suitable for functional garments.

First, the user can select the functional garment program in the program selection part 117 (S1510). Once the user selects the functional garment program, the control part can initiate a wash cycle, a rinse cycle and / or a sequential or selectively spin cycle.

F.1 Washing cycle (S1530):

F.1.1 Water supply (S1531):

The control part implements a water supply stage of a wash cycle. The water supply stage supplies wash water necessary to wash clothes. In addition, the water supply stage dissolves the detergent in the supplied wash water and moisturizes the laundry loaded in the drum.

F.1.1.1 First supply (S1533) of water:

The water supply stage includes a first water supply stage implemented for a predetermined period of time. In the first stage of water supply, the drum can be operated in the oscillation movement. As mentioned above, the oscillation movement rotates the drum in a predetermined direction and one in the opposite direction as an alternative. After having turned 90 ° or less from the lowest point of the drum in the predetermined direction and in the opposite direction, the clothes can be dropped. As a result, the alternative clockwise / counterclockwise rotation generates a vortex in the wash water and the detergent solution can be promoted. At the same time, clothing that has been turned 90 ° or less is dropped and the great impact does not apply to clothing. Due to this, the oscillation movement in the first stage of water supply allows the detergent to dissolve in the wash water and a great impact is not applied to the functional garments. The oscillation movement can be repeated for a predetermined period of time, several times.

F.1.1.2 Second water supply (S1535):

Once the first water supply is completed, a second water supply can be implemented for a predetermined period of time. In the second water supply, the wash water is supplied continuously and the filtration movement and the oscillation movement are applied sequentially. The first and second stages of water supply can be classified according to a pre-established time. The time of each stage can be adjusted according to the amount of clothing and other parameters as appropriate. Therefore, a stage for determining the amount of clothing configured to determine the amount of clothing can be provided before the water supply stage.

As mentioned above, the filtration movement rotates the drum at high speed to generate the centrifugal force and the clothes are in close contact with the inner circumferential surface of the drum due to the centrifugal force. Also, the wash water passes through the clothes and the through holes of the drum by centrifugal force and is discharged into the tank. As a result, the clothes are moistened by the washing water in the filtration movement for washing. In addition, the washing water passes through the clothes simply the functional garments cannot be damaged while they are wetted in the washing water. After the filtration movement is performed for a predetermined period of time, the oscillation movement can be implemented. As mentioned above, the detergent can be dissolved continuously, without damage to functional garments. The clothes can be effectively moistened in the wash water by the generated vortex and, by extension, the oscillation movement generates the drum rotation repeated clockwise / counterclockwise. Because of that, tangled clothing can be separated before washing. In addition, the oscillation movement drops the clothes from a relatively low position and damage to the fabric of the clothes can be minimized while the clothes are unraveled. As a result, the combination of filtration and oscillation movements can minimize the damage of functional garments and allow wetting of clothes, dissolution

detergent and unraveling of clothes that must be achieved effectively. Such a sequential combination of filtration and oscillation movements can be repeated several times over a predetermined period of time.

F.1.2 Washing (S1540):

Once the wash water is supplied at a predetermined water level, the water supply stage is completed and then a washing stage can begin. While functional garments are relatively light and thin, essentially the same washing stage can be implemented, regardless of the amount of clothing in the drum.

F.1.2.1. First wash (S1541):

The washing stage may include a first washing stage implemented for a predetermined period of time, with the drum driven in the progressive movement. As mentioned earlier, the progressive movement drops the clothes from the highest position. As a result, the progressive movement in the first washing stage mixes the garments evenly and the wash water preliminary. In addition, the progressive movement soaks the contaminants in the clothes and applies the impact to the clothes to separate the contaminants from the dirty clothes by using the large twist / fall of the clothes.

F.1.2.2. Second Wash (S1543):

After the first wash stage, a second wash stage can be implemented for a predetermined period of time. In the second washing stage, the washing water is heated for a more efficient washing and removal of contaminants. First, the wash water can be heated by a heater arranged on a lower surface of the tank or a steam generating device configured to supply steam to the tank. Substantially, the wash water can be heated to about 25 ° C to 30 ° C, preferably, to about 27 ° C in the second wash stage. Functional garments are made of fine synthetic fabric texture and can be damaged if the temperature of the hot wash water is excessively high. As a result, washing water that has a suitable temperature used in the second washing stage can improve washing efficiency and can prevent tissue damage.

Simultaneously with the heating of the washing water, the drum can be operated in the oscillation movement in the second washing stage. The swing movement uses the fall of the clothes from the relatively low position and the alternative rotation of the drum. Because of that, clothes can be gently rotated and moved enough in the wash water. The wash water in the oscillation movement can be heated uniformly in a relatively short time and the heat can be transmitted to the clothing sufficiently. In addition, the oscillation movement can generate a discharge due to friction between the wash water and the clothing and the impact of falling and can effectively remove contaminants without damaging the fabric.

F.1.2.3. Third wash (S1545):

After the second wash stage, a third wash stage can be implemented for a predetermined period of time. In the third wash stage, any remaining contaminants can be removed and a combination of oscillation and progressive movements can be implemented. Although the oscillation movement can remove contaminants without damaging the fabric as mentioned above, the washing capacity is relatively low compared to the other movements. As a result, the progressive movement capable of applying a stronger impact is added and the washing capacity of the especially configured washing stage of the oscillation movement for the functional garments can be improved. In addition, the strong impact of progressive movement can prevent lint from sticking to clothing. As a result, the third stage of washing can minimize damage to functional garments and separate contaminants from clothing completely and effectively.

F.2. Rinse cycle (S1550):

A rinse cycle of the functional garments cycle may be similar to the rinse cycles of the programs including the aforementioned standard program and the rinse cycles of the other programs which will be described below and therefore a further detailed description thereof. will skip

To reinforce the overall washing capacity, the rinse cycle can be repeated more often than the rinse cycle of the standard program. For example, the rinse cycle can be implemented at least three times or more. This is because the drum is rotated at a lower RPM in a spin cycle of the functional garments cycle than in the standard program thus providing a weaker rinse capacity. That is, the spin cycle separates the wash water from the laundry using the centrifugal force generated by the high speed rotation of the drum and can provide a rinse function configured to separate the detergent and contaminants along with the wash water. of clothes simultaneously. A normal spin stage of the spin cycle of the functional garment program uses a relatively low RPM of drum rotation and the final rinse capacity can be weakened. Therefore, the rinse stage of the wash cycle of the functional garment program can be implemented three times or more.

F. 3 Cycle (S1570) spin:

A spin cycle of the functional garments cycle may be similar to the spin cycles of the cycles including the standard program mentioned above and the spin cycles of the other programs that will be described later. A normal spin stage of the spin cycle can rotate the drum at a lower RPM than the normal spin stage of the standard program, to avoid damage to clothing.

G. Program G (quick wash program):

A quick wash program G, which is referred to as a 'quick wash program' capable of washing clothes in a relatively short time, compared to the other programs, will be described with respect to Figure 26. A small amount of clothes It normally requires a substantially short period of time compared to a large amount of dirty clothes. In the case of a small amount of clothing, an unnecessarily long period of time can be taken to implement general washing. Because of that, a program used to wash a small amount of dirty clothes in a short period of time can be provided. The rapid wash program is based on the standard program described above with respect to Figure 7, and each cycle or operating conditions of each stage in the standard program can be optimized, or a predetermined number of stages can be omitted as appropriate.

First, the user can select the quick wash program in the program selection part 117 (S710B) and the control part can implement a wash cycle (S730B), a rinse cycle (S750B), and a cycle (S770) spin that make up the quick wash program.

G.1 Washing cycle:

G.1.1 Determination of the amount of clothing:

The control party may begin a step of determining the amount of clothing to determine the amount of clothing (S731B). The step of determining the amount of clothing can be implemented before a water supply stage that starts after the user selects the quick wash program. The quantity of clothing measured in the stage quantity of clothing determining the standard program as described above can be classified into two categories, that is, a large quantity and a small quantity, to determine the next drum cycle or movement of each stage and Other operating conditions. In the rapid wash program, the amount of clothing measured can be used to determine the overall total wash time, that is, the total time needed to complete the wash, rinse and spin cycles as well. In this case, the amount of clothing can be specified in more categories, for example, three or more categories in the quick wash program. If the quantity of clothes is classified into more categories, a different total washing time (that is, the total time needed to complete the washing, rinsing and spin cycles) can be set for each of the categories of the quantity of clothes . As a result, the total washing time can be controlled corresponding to the amount of clothing. Because of that, a relatively short time can be properly applied to a small amount of clothing without deteriorating the actual washing capacity.

For example, the amount of clothing measured can be classified into three categories including first, second and third categories, or it can be classified into more than three categories. For example, the first category corresponds to a load of less than 1.5 kg and an adequate washing time of the first category can be set to be approximately 25 to 30 minutes, in particular 29 minutes. The second category may correspond to a load of approximately 1.5 to 4.0 kg and a suitable washing time of the second category may be set to approximately 35 to 40 minutes, in particular 39 minutes. Finally, the third category may correspond to a load of more than approximately 4.0 kg and an adequate washing time of the third category may be 45 to 50 minutes, and in particular, 49 minutes.

Once the quantity of clothing is determined at the stage of determining the quantity of clothing, the control party determines to which category the quantity of clothing measured corresponds, referring to the stored category table. After that, the control part can adjust the washing time according to the category corresponding to the amount of clothing measured at a real washing time.

G. 1.2. Water Supply / Heating / Washing:

After the series of previous steps, the control part can sequentially apply a water supply stage (S733B), a heating stage (S740B) and a washing stage (S742B) of the washing cycle (S730B). The water supply stage, the heating stage, the washing stage of the wash cycle of the rapid wash program are similar to those of the wash cycle of the standard program shown in Figure 7 and therefore an additional description Detailed of them will be omitted.

As mentioned earlier in the standard program shown in Figure 7, a heating preparation stage configured to promote washing water heating can be implemented before a heating stage. However, the heating preparation stage may be a preliminary stage and a drum movement for a predetermined period of time may increase the total time.

washing As a result, preliminary steps such as the heating preparation stage before the heating stage cannot be implemented in the rapid wash program. After the water supply program, the heating stage can begin.

G.2 Rinse cycle:

Once the wash cycle has been completed, a rinse cycle (S750B) configured to remove detergent residue and contaminants that remain in the laundry can be implemented. The rinse cycle (S750B) is similar to the rinse cycle (S750) of the standard program shown in Figure 7 and therefore a more detailed description of the rinse cycle will be omitted.

The first rinse stage implemented in the initial rinse cycle stage of the standard program may include the first drum drive stage through the time-consuming filtration movement. On the contrary, the movements of the drum applied in the stages (S751B, S756B, S760B) of rinsing require a relatively short time, while still providing enough rinsing to the clothes. As a result, the filtration movement of the first rinse stage provided in the rinse cycle of the Quick Wash Program can be omitted to reduce the total wash time.

G. 3 Spin cycle:

Once the rinse cycle has been completed, the control part can initiate a spin cycle (S770B). The spin cycle of the Quick Wash Program is similar to the spin cycle of the standard program shown in Figure 7 and therefore a further detailed description thereof will be omitted.

The unraveling stage of clothes implemented in the initial stage of the spin cycle of the standard program implements a drum movement capable of unraveling the clothes. However, such drum movement cannot affect the spin capacity substantially. Because of that, the unraveling stage of clothes cannot be implemented in the spin cycle of the quick wash program to reduce the total washing time.

While the drum in the normal spin stage of the standard program can be rotated at about 1000 RPM, the drum in a normal spin stage of the quick wash program can be rotated at about 800 RPM. As the speed of rotation of the drum increases, the vibration and noise of the drum can become more severe and the preparation steps implemented so that the drum reaches the target RPM such as the eccentricity measurement stage can be repeated enough as to require a relatively long operating time. As a result, the target spin speed of the fast wash program is reduced compared to that of the standard program and the speed acceleration time can be prevented from increasing.

As mentioned above, the quick wash program can classify the wash quantities into specific categories and can adjust the total washing time appropriate to each category, so that the total washing time of the large amount of clothing, as well As the small amount of clothing can be reduced properly. In addition, compared to the standard program, unnecessary steps can be omitted from the cycles to reduce the total washing time. However, most drum movements applied to the standard program cycles are adapted in the fast wash program and the desired washing capacity can be achieved. As a result, the quick wash program can wash a small amount of the clothes in a short time, while maintaining the washing capacity.

H. Program H (silent program):

Program H will be described with reference to Figure 16. Program H can be called 'silent program' capable of reducing noise during washing.

In certain circumstances, less noise from the washing machine may be required by the user. For example, if washing is done at night and / or a baby or child is asleep, it is preferable that the washing machine operates with less operating noise. Operation noise reduction can be achieved in several ways. The optimization of a washing control procedure can reduce noise effectively, without increasing the cost of production. The washing control procedure configured to reduce such noise can be performed by a single program, in particular, a silent program presented by the optimization of the operating conditions. The silent program is based on the standard program and is materialized by optimizing or omitting certain operating conditions of certain cycles or stages of the standard program. Figure 16 is a flow chart of the different stages of the silent program of the standard program stages. First, the user can select the silent program in the program selection part 117 (S1610) and the control part can implement a following series of operations.

The control party may begin a step of determining the amount of clothing to determine the amount of clothing. The step of determining the amount of clothing has been described above and therefore a further detailed description thereof will be omitted. An object of the silent program is to reduce noise and / or vibration while maintaining the washing capacity. A drum drive movement of each stage can be differentiated depending on the quantity of clothes.

H.1.1. Water supply (S1633):

Once the user selects the silent program, a water supply stage can begin. The water supply stage supplies wash water to the tank. In addition, the water supply stage dissolves the detergent mixed with the wash water and moisturizes the laundry loaded in the drum. In the water supply stage of the silent program, the control part can supply a greater amount of wash water to the tank, compared to the water supply stage of the standard program. The reason why more washing water is supplied will be described in a subsequent washing step.

H.1.1.1 First water supply (S1635):

In the water supply stage, the control part may implement a first water supply stage, together with the washing water supply. In the first stage of water supply, the control part controls the drum to actuate in the turning movement.

As mentioned above, the rotational movement rotates the drum in a predetermined direction continuously and the clothes are separated from the drum after they have been turned to the position of 90 ° or less with respect to the direction of rotation of the drum from the lowest point of the drum. In the turning movement, the drum is rotated at a relatively low speed and the clothes separated by the spin move on the inner surface of the drum to the lowest point of the drum, without falling to the lowest point. Due to that, the rotation of the drum and the rotational movement of the clothes can generate a predetermined vortex in the washing water and the dissolution of detergent in the washing water can be promoted. At the same time, the turning movement induces the rotating movement of the clothes along the inner surface of the drum and that there may be no noise from the impact generated by the sudden drop of the clothes. As a result, the turning movement in the first stage of water supply may allow the detergent to dissolve sufficiently in the wash water while reducing noise. In the first stage of water supply, the turning movement can be repeated for a predetermined period of time a number of times.

H.1.1.2 Second water supply (S1637):

Once the first water supply stage has been completed, the control part can initiate a second water supply stage. In the second stage of water supply, the control part can control the drum to actuate in the filtration movement and the sequentially rotating movement, with the supply of washing water to the tank continuously. The first and second stages of water supply can be distinguished from each other according to the respective predetermined time and the time of each stage can be adjusted according to the amount of clothing.

As mentioned above, the filtration movement rotates the drum at a high speed to generate a centrifugal force and the generated centrifugal force keeps the clothes in close contact with the inner circumferential surface of the drum. Also, the wash water passes through the clothes and the through holes of the drum by the centrifugal force that is discharged into the tank. As a result, the clothes are moistened by the wash water in the filtration movement. In addition, the washing water passes through the clothes simply and the clothes cannot be damaged while being wetted in the washing water. After the filtration movement is performed for a predetermined period of time, the rotational movement can be implemented. As mentioned above, the turning movement in the first stage of water supply may allow the detergent to dissolve sufficiently in the wash water while reducing noise. Also, a wider surface area of the clothing is brought into contact with the wash water, rotates along the inner surface of the drum, and therefore the clothes can be wetted in the wash water so More effective and uniform. As a result, the combination of filtration and spinning movements can minimize noise and allow the wetting of clothes, detergent solution and unraveling clothes to be carried out effectively. Such a sequential combination of the filtration and rotation movements can be repeated several times for a predetermined period of time.

H.1.2 Washing (S1635):

Once the wash water is supplied at a predetermined water level, the water supply stage is completed and then a washing stage can begin.

H.1.2.1 Heating stage / First wash (S1640):

Once the water supply stage is completed, the control part starts a first washing stage. The first wash stage may include a heating stage configured to heat the wash water to a

default temperature Unlike the heating stage and the washing stage of the standard program, the first washing stage of the silent program may include only the turning movement. The turning movement allows the clothes to move in rotation along the inner surface of the drum without suddenly dropping the clothes. As a result, such a turning movement can maximize the friction between the dirty clothes and the washing water and between the clothes and the drum and the washing stage can remove the contaminants from the clothes effectively, with less noise.

As mentioned above, the control part in the water supply stage can supply a greater amount of wash water, compared to the water supply stage of the standard program. For example, the control part can control the amount of washing water supplied in the washing stage of the silent program to be 1.2 times more than the amount of washing water supplied to the same amount of laundry. The increase in the amount of wash water results in an increase in the level of water inside the drum. When the clothes are rotated in the drum with the increase of the water level by the turning movement, the friction between the washing water and the clothes can be increased further and the washing capacity can be further improved. Finally, the rotation movement adapted in the washing stage can provide adequate washing capacity while suppressing noise generation.

Once a predetermined amount or more of the clothes are loaded into the drum, the slow spin speed of the drum cannot easily rotate the clothes along with the drum. Even if it rotates along with the drum, the large amount of clothing may have difficulty moving in rotation on the inner surface of the drum due to the volume. As a result, since the spinning movement rotates the drum at a relatively low speed, the large amount of clothing does not move in rotation as intended and, therefore, cannot achieve the desired washing capacity. Because of this, in the case of washing a large amount of clothes, the washing stage can adapt a drum movement different from the turning movement described above.

That is, when the amount of clothes measured in the stage of determining the amount of clothes is greater than a predetermined reference value, the flipping movement can be implemented in the washing stage, instead of the turning movement. The turning movement rotates the drum in the predetermined direction continuously, similar to the turning movement, and the rotation speed of the drum in the turning movement is greater than that of the drum in the turning movement. As a result, the clothes are separated from the drum after having been turned to the position of 90 ° or more with respect to the direction of rotation of the drum from the lowest point of the drum. Since the drum is rotated at a relatively high speed in the turning movement, the separated clothes are dropped to the lowest point of the drum and this is different from the turning movement. As a result, the clothes can be washed by the impact generated by friction between the dirty clothes and the wash water and the fall. Although the turning movement generates more noise than the turning movement, the generated noise may be less than the noise generated in the other drum movements such as the progressive movement and the rubbing movement that have a strong washing capacity. Because of this, the flipping movement can wash a large amount of clothing effectively, while suppressing noise generation as much as possible. When the amount of clothing measured is less than the reference value, the turning movement can be implemented as mentioned above.

To promote the heating of the wash water, a heating preparation stage can be implemented before a heating stage. However, the heating preparation stage may include a drum movement and the drum movement may generate noise. As a result, preliminary stages such as the heating preparation stage before the first washing stage cannot be implemented in the washing stage of this program and the washing water can be heated to a predetermined temperature in the first stage of washed. The wash water can be heated by the heater or the steam generating device installed in the tank.

H.1.2.2 Second wash (S1642):

The control part may initiate a second washing stage after the first washing stage. Contaminants can be removed more completely in the second wash stage. Like the first washing stage, the second washing stage of the silent program can include only the turning movement. The noise generation can be minimized in the turning movement and the contaminants in the clothes can be effectively removed in the turning movement, as described above. In addition, a greater amount of washing water is supplied in the turning movement, compared to the amount of washing water supplied in the standard program. Due to that, the rotation movement adaptation can guarantee sufficient washing capacity, while also suppressing noise generation.

If the amount of clothing is large, the drum is actuated in the flipping motion. If the amount of clothing is small, the drum is actuated in the turning movement, similar to the first washing step described above.

H.2 Rinse cycle (1650):

Once the wash cycle has been completed, a rinse cycle set to remove detergent residue and contaminants from clothing can begin. The rinse cycle is similar to the rinse cycles of the standard program described above and therefore a further detailed description thereof will be omitted.

The first rinse stage implemented in the initial rinse cycle stage of the standard program includes the first drum drive stage through the filtration movement, which can generate a lot of noise. As a result, the filtration movement is not implemented in the rinse cycle of the silent program. Although the stages of the rinse cycle of the standard program can adapt different drum movements, the silent program can apply only the rotational movement of the stages of the rinse cycle to reduce noise as in the washing stage.

To reinforce the general rinse capacity, the rinse stages are repeated more times in the silent program than in the standard program. For example, the rinse cycle can be implemented four times or more. This is because the drum is rotated at a lower RPM in the spin of the silent program than in the spin cycle of the standard program, thus deteriorating the rinse capacity. That is, in the spin cycle, the washing water is normally separated from the clothes by the centrifugal force generated by the high speed rotation of the drum and the detergent and the contaminants are separated from the clothes together with the washing water of simultaneously. However, in the normal spin stage of the spin cycle of the silent program, the drum is rotated at a lower RPM and, therefore, the final rinse capacity may deteriorate. As a result, the washing steps can be implemented four or more times in the rinse cycle of the silent program.

H. 3 Cycle (S1670) spin:

Once the rinse cycle has been completed, the control part can initiate a spin cycle. The spin cycle is similar to the spin cycle of the standard program and therefore a further detailed description thereof will be omitted.

In a normal spin stage of the silent program, the drum can rotate at a lower RPM than in the normal spin stage of the standard program to reduce noise. For example, to reduce noise, the drum can rotate at a predetermined RPM that is 50% of the RPM of the normal spin cycle of the standard program. That is, the drum can rotate at approximately 400 RPM.

I. Program I (mixed, cotton, synthetic programs)

Like the functional garment program described above, programs corresponding to the types of laundry items and for types of cloth can be provided. For example, a cotton program configured to wash cotton fabrics such as towels, tablecloths, t-shirts and the like, a synthetic program or easy care program configured to wash synthetic fabric, and a mixed program configured to wash a mixture can be provided of types of fabrics such as cotton and synthetic fabrics. The synthetic material may include, for example, polyamide, acrylic, polyester and other fabrics.

Cotton fabric and synthetic fabric have different characteristics. That is, cotton fabric is more resistant to friction and impact, with less worry of deformity, than synthetic fabric. In addition, cotton fabric can absorb more wash water than synthetic fabric and has less wrinkle concern than synthetic fabric. However, it is not easy to separate cotton cloth wash items from synthetic cloth wash items or implement corresponding wash programs to wash them separately all the time. This is because the user normally wears garments made from cotton and synthetic fabric together, and does not want to wash separate partial loads of cotton garments and synthetic fabric. As a result, a washing program that combines the cotton program and the synthetic program is merited, that is, a mixed program can be provided.

The mixed program can be useful for many reasons. For example, if the user separates cotton cloth garments and synthetic cloth garments to wash them separately, the washing can be delayed disadvantageously until a predetermined amount of clothing is collected and therefore the clothing Contaminated can be neglected for a relatively long time. Of course, if a small amount of dirty clothes is washed separately, energy can be wasted. Because of that, the mixed program capable of washing conventional types of cloth garments together can avoid the problem of neglecting clothes and wasting energy.

In the washing program provided corresponding to such mixtures of fabric types shown in Figure 17, a wash cycle, a rinse cycle and a spin cycle can be differentiated depending on the characteristics of the particular type of fabric. As follows, the cotton program, the synthetic program and the mixed program having the operating conditions of each stage adjusted based on the type of fabric will be described with reference to the cycles and stages of the standard program described above. In comparison to the standard program, the repeated detailed description will be omitted where appropriate, and the difference will be described in detail.

Once the user selects the cotton program, the synthetic program or the mixed program (S1710) according to the type of fabric of clothing, the control part can implement a wash cycle (S1730), a cycle (S1750 ) rinse, and a spin cycle (S1770) and stages according to the selected program.

1.1.1 Stage (S1734) for determining the amount of clothing:

The control party may determine the amount of clothing in a wash cycle and a procedure for determining the amount of clothing in this program is similar to the above procedures and a repeated description will be omitted. The amount of clothing measured can be used in a next stage correctly, which will be described in detail.

I.1.2. Water supply stage (S1733):

The control part can implement a water supply stage configured to supply washing water and detergent to the tank or drum and to dissolve the detergent in the washing water. That is, the wash water is supplied from an external water supply source, together with the detergent. To supply the wash water and laundry detergent initially, the wash water and detergent are supplied to the laundry contained in the drum directly. That is, a water supply path of the wash water can be placed in a front upper portion of the drum towards the inner drum, not in a lower portion of the tank. When the detergent is a type of powder, the detergent solution is not sufficiently implemented and a drum drive movement of the water supply stage, which will be described later, can dissolve sufficient detergent. As a result, the wash water and the detergent are supplied to the clothes in the initial stage of the wash cycle and the time required by the wash cycle can be reduced to improve the washing efficiency.

1.1.2.1 Promotion (S1735) of detergent solution:

In a stage of promoting the detergent solution, a drum drive movement can be differentiated according to the type of wash cloth. For example, the rubbing movement can be implemented for cotton cloth garments and the progressive movement can be implemented for synthetic cloth garments. In alternative embodiments, the rubbing movement and / or the progressive movement can be implemented.

The rubbing movement folds / stretches and rubs the clothes by dropping the clothes, to generate friction. Because of that, an effect similar to hand rubbing can be expected in the initial stage of the wash cycle. However, this rubbing movement can be implemented for the fabric that is somewhat resistant to friction and the drum driving movement may be the rubbing movement at the stage of promoting the detergent dissolution of the cotton program.

According to synthetic fabric characteristics, synthetic fabric garments are lighter than cotton cloth garments and synthetic fabric garments have a lower percentage of water than cotton cloth garments. . Also, synthetic fabric garments have a greater concern for the damage caused by the friction of cotton cloth garments. Because of that, progressive movement can be implemented at the stage of promoting detergent solution to promote detergent dissolution and preventing damage to the fabric. That is, a drum drive movement at which stage of promoting the detergent solution for the synthetic fabric may be the progressive movement. The progressive movement applies the maximum impact of fall to the light synthetic fabric to promote the dissolution of detergent and the washing effect similar to using the hands can be expected in the initial stage of the washing cycle.

A one-stage drum drive movement of promoting detergent dissolution in the mixed program may be a combination of the progressive movement and the rubbing movement. That is, the progressive movement and the rubbing movement that are optimal for the cotton tile and the synthetic fabric, respectively, can be combined in such a way that the detergent solution can be promoted and the washing effect can be expected in the initial stage. of the wash cycle. In this case, the different drum drive movements are combined and because of that, the movement patterns of the laundry and movement patterns of the wash water can be diverse enough to improve the effectiveness of the wash cycle.

1.1.2.2 Wetting (S1736) of clothing:

In the wetting stage of the standard program, the drum can rotate in the turning movement. The turning movement generates less friction applied to the clothes than the previous rubbing movement and the turning movement is performed in a period that has the wetting of clothes implemented. As a result, although friction is applied between wet wash items, there will be little concern of clothing damage and the clothes wetting stage implemented in the spinning movement can be implemented in a similar manner, regardless of the types of fabric the clothes.

Regardless of whether the fabric is made of cotton or synthetic, the spinning movement can be implemented at the stage of wetting clothes. Even when the user selects any one of the cotton program, the mixed program or the synthetic program, the spinning movement can be implemented at the stage of wetting clothes after the stage of promoting detergent dissolution.

The clothes wetting stage may include two stages that include first and second clothes wetting stages that are implemented separately. For example, when the clothes wetting stage is performed for 10 minutes, the first clothes wetting stage can be implemented for 5 minutes and the second clothes wetting stage can be implemented for 5 minutes. Specifically, the additional water supply can be implemented in the first stage of wetting clothes and the second stage of wetting clothes can be implemented once the additional water supply has been completed.

The drum drive movements of the first and second stages of wetting clothes can be differentiated to moisten the clothes more efficiently and supply both the detergent and the wash water to the clothes evenly. For example, the driving movement of the drum of the first stage of wetting clothes can be the turning movement and the driving movement of the drum of the second stage of wetting clothes can be a combination of the turning movement and the movement of filtration. That is, the turning movement can be implemented in a predetermined net action in the first stage of wetting clothes. In the second stage of wetting clothes, after the filtration movement is performed once, the turning movement is performed four times and this is made up of a single cycle. The cycle can be repeated.

The turning movement continuously dumps the clothes on the bottom of the drum to increase the contact time between the washing water and the detergent continuously. The filtration movement spreads the clothes widely and allows the washing water and the detergent to be supplied to the clothes in a uniform manner, so that an effective wetting of clothes may be possible. It may normally take approximately 13 minutes to complete the wetting of the clothes in the flipping movement, while the wetting of clothes may take approximately 10 minutes according to this embodiment.

The drum drive movement of the first stage of wetting clothes can be differentiated depending on the amount of clothes. The driving movement of the drum of the first stage of wetting clothes can be differentiated according to the amount of clothes determined in the stage of determining the amount of clothes. For example, if the amount of clothing determined is a predetermined level or more, the drum is actuated in the turning movement as mentioned above. If the amount of clothing determined is less than the predetermined level, the drum can be operated in a combination of progressive and turning movements.

The progressive movement suddenly drops the clothes after lifting it. If the amount of clothing is large, the distance of the washing drop can be reduced. Therefore, the progressive movement is suitable for a small amount of clothing. Such progressive movement could cause damage to clothing. As a result, in the cotton program, when the amount of clothing is lower than the predetermined level, the combination of progressive movement and spinning movement can be implemented in the first stage of wetting clothes. When the amount of clothing is the predetermined level or more, the spinning movement can be implemented in the first stage of wetting clothes. In the synthetic program and the mixed program that has the concern of damaging clothes, the spinning movement can be implemented in the first stage of wetting clothes, regardless of the amount of clothing.

In alternative embodiments, a circulation stage can be implemented in the water supply stage, in relation to the drum drive. That is, the circulation stage may be synchronized with the motor drive configured to drive the drum. The washing water that is circulated when the clothes are moved by the drum drive can be supplied to the clothes and the object of the water supply stage can be achieved more effectively.

The stage of promoting the detergent solution and the clothes wetting stage are included in the water supply stage according to this embodiment. However, the stage of promoting detergent dissolution and the clothes wetting stage could be provided independently of the water supply stage. In this case, after the water supply, the stage of promoting the dissolution of detergent or the stage of wetting clothes can be implemented.

I.1.3. Heating (S1741):

A heating stage can be differentiated according to the operating program selected in this program. For example, the temperature of the wash water used in the heating stage can be adjusted differently depending on the type of fabric of the clothes.

Cotton tile is somewhat heat tolerant. As the temperature of the wash water increases, more detergent dissolves in the wash water and the activation of the detergent is further promoted. As a result, when the cotton program is selected, the washing water temperature can be set to be approximately 60 ° C in the heating stage. A washing water temperature of this type can be selected from a range that ranges from cold water to water at approximately 95 ° C through option selection part 118. As the temperature of the wash water increases, detergent activation can be further promoted and the washing capacity can be further improved, further improving a sterilization / bleaching effect if appropriate.

Synthetic fabric may be more subject to / be less tolerant of heat and therefore the synthetic program or mixed program aims to prevent heat from damaging clothing. When the synthetic program or the mixed program is selected, the wash water temperature can be set to be approximately 40 ° C in the heating stage. In the synthetic program or the mixed program, the user can prevent the selection of the washing water temperature from exceeding 60 ° C, to avoid damage to the clothing. For example, when the synthetic program or the mixed program is selected, the temperature of the wash water in the heating stage may have the highest limit of 60 ° C.

A drum drive movement of the heating stage may be the flipping movement, regardless of the selected program. This is because the flipping movement can unravel the clothes, while reducing the damage to the clothes. As a result, the flipping movement can allow enough steam or hot wash water to be transmitted to clothing.

In alternative embodiments, a circulation stage can be implemented in the heating stage. The circulation stage may be synchronized with the drum drive. Since the circulation stage is performed after an initial heating is implemented to a predetermined degree, the circulation stage can be synchronized with the drum drive at a predetermined time after the initial drum drive starts.

I.1.4 Washing (S1742):

A drum drive movement of a washing stage may be a sequential combination of the turning movement and / or the turning movement and / or oscillating movement. The drum drive movement of the washing stage can be differentiated according to the selected program, because both the protective effect of the fabric and the effect of improving the washing capacity have to be achieved.

That is, in the case of washing cotton cloth clothes, a drum drive movement configured to wash the clothes using a strong mechanical force can be implemented. In the case of washing synthetic fabric clothes, a drum drive movement configured to wash dirty clothes by using a relatively low mechanical force can be implemented. The washing stage may include one of the washing cycle stages, which requires a longer time. As a result, the washing step can be controlled to implement a more efficient washing. Since the necessary time of the washing stage is long, it is likely to generate more damage to the clothes during the washing stage.

Taking into account that, the drum can be operated in combination of the turning movement and the turning movement in the washing stage when the cotton program is selected. The combination of the two different movements applies different patterns of strong mechanical strength to the clothes and the washing efficiency can be improved. That is, according to the characteristics of the cotton fabric, there is little concern to damage the fabric. Because of that, strong mechanical force is applied to wash clothes and the washing effect can be further improved. When the cotton program is selected, a combination of the filtration movement and the turning movement can be implemented in a washing stage, with the circulation stage synchronized with the drum drive. Since the cotton tile has little concern of damaging the clothes, the filtration movement can supply the washing water and the detergent to the clothes continuously and effectively.

In contrast, when the synthetic program is selected, the drum can rotate in a combination of the oscillation movement and the turning movement in the washing stage. The combination of the two different movements can improve the washing effect. The oscillation movement makes the clothes oscillate in the wash water gently and thus the damage to the clothing generated by friction can be minimized. In addition, the time in which the clothes are in contact with the wash water can be increased sufficiently to improve the washing effect.

As the mixed program is provided to wash both cotton cloth garments and synthetic cloth garments together effectively, the washing effect has to be improved and clothing damage has to be reduced as much as possible. , regardless of the type of washing cloth. To satisfy this, the drum drive movement of the wash stage when the mixed program is selected may be a combination of the flipping movement and / or oscillating movement and / or turning movement. That is, the oscillation movement configured to prevent tissue damage can be provided and the rotational movement configured to improve the washing capacity can be provided.

In the synthetic program and the mixed program, a circulation stage can be synchronized with the drum drive to allow both the supply of washing water and detergent to the laundry continuously.

As mentioned above, although one of the cotton program, synthetic program or the mixed program is selected, the drum drive movements of the washing stage can be controlled for a combination of two different movements. This is to generate various patterns of mechanical strength and movement of clothing and to improve user satisfaction visually.

When a level of laundry contaminants is selected in part 118 of the selection of options, the net engine performance ratio can be adjusted according to the selected contaminant level. However, increasing the net ratio that acts also increases the time that mechanical force is applied to clothing. Taking into account that, the net action ratio of the wash cycle can be differentiated according to the program selected by the user. That is, the net performance ratio of the cotton program may be larger than that of the synthetic program and of course that of the mixed program.

I.1.2 Rinse cycle (S1750):

Once the wash cycle has been completed, a rinse cycle can begin. In the rinse cycle, the steps configured to drain the wash water after the clothes are rinsed with the supplied wash water 10 can be repeated. The rinse stage of the rinse cycle in this program can be repeated three times or more.

The wash water can be supplied for a rinse cycle water level that is higher than a wash cycle water level. That is, the wash water can be supplied at a predetermined water level that is visible from the outside to improve the rinsing effect by using enough washing water.

15 A driving movement of the rinse cycle drum can be the turning movement. The flipping movement immerses / removes clothes from / in the wash water and this can be repeated. The high water level together with the flipping movement visually notifies the user of sufficient rinse. The turning movement of the rinse cycle can prevent motor overheating thereby improving the rinse efficiency. That is, the water level of the rinse cycle may be higher than that of the wash cycle and the load applied to the drum can be increased by the wash water accordingly. The progressive movement, the rubbing movement and the oscillating movement repeat the rotation and braking of the motor. As a result, such a brake can generate an excessive load on the engine. In addition, if the water level is high, the load generated by the wash water can be increased. In the rinse cycle that has a high level of water, the drum drive movement has no sudden brake to prevent motor overheating. Therefore, the turning movement 25 configured to rotate the drum in the predetermined direction may be preferable in the rinse cycle.

A circulation stage can be implemented in the rinse cycle to circulate the wash water contained in the tank inside the drum. This can generate a visual notification effect to the user of sufficient clarification.

I.3. Spin cycle (S1770):

30 Once the wash cycle and rinse cycle have been completed, a spin cycle configured to discharge the laundry water as much as possible can be implemented. In a normal spin stage of the spin cycle, the drum RPM can be differentiated according to the program selected by the user, taking into account the percentage of water content and residual wrinkle formation according to the type of tissue .

35 Cotton fabric has a high percentage of water content or absorption, with less worry of wrinkles. Even if there are wrinkles generated on the cotton tile, it is easy to remove the wrinkles. In contrast, synthetic tissue has a low percentage of water content or absorption, with great concern of wrinkles. As a result, in the cotton program, the preset RPM may be higher than those of the synthetic program and mixed program, and the preset RPM may be, for example, 1000 RPM or more. Here, the RPM of the centrifugation can be changed through the user selection part.

The preset RPM of the synthetic program and the mixed program can be set to be 400 to 600 RPM. Even when synthetic cloth garments are centrifuged at a low RPM, the wash water can be discharged from the synthetic cloth garments sufficiently and wrinkles can be avoided. In this case, the RPM of the centrifugation can be changed through the option selection part by the user. In certain embodiments, the centrifugation RPMs are set to a maximum of 800 RPM.

J. Program J (wool program):

A washing program provided according to a type of fabric of clothing may also include a wool program, instead of the cotton program, synthetic program and mixed program. The wool program applies to clothes that have fewer contaminants and a great concern for damaging the fabric. That is, the wool program can be provided for washing clothes of woolen fabrics that are hand washable. If washed using a strong mechanical force, woolen garments are prone to damage. As a result, in the wool program, the drum is operated in a predetermined movement having a weak mechanical force, for example, the oscillating movement. Taking into account the characteristics of the wool fabric, the drum drive movements of a wash cycle, a rinse cycle and a spin cycle of the wool program may be different from the drum movement of the standard program.

J.1. Wash cycle:

In the wool program, it is important to avoid damage to the fabric and the drum can be operated in the oscillation movement configured to move the clothes to the right and to the left in a lower portion of the drum gently, in a wash cycle of the Wool Program. In this case, a water level may be high enough to allow a drum water level inside to be visible from the outside. Because of that, the friction between the inner circumferential surface of the drum and the clothes can be minimized and the elevations that touch the clothes can be repeated, spinning the clothes immersed in the washing water, and this prevents damage to the clothes and allows the Implementation of washing or rinsing is subtle. This oscillating movement can minimize damage to the clothes and increase the contact time with the washing water and the detergent with the clothes to improve the washing effect.

The wool program is shown in Figure 18. A washing cycle of the wool program is selected (S1810). In an initial stage of the wash cycle (S1830), the wash water and detergent can be supplied to the tub or drum, that is, a water supply stage (S1833) can be implemented. The water supply stage may include a stage (S1835) of promoting detergent dissolution and a stage (S1836) of wetting clothes. The stage of promoting the detergent solution is configured to promote the dissolution of the detergent applied at an initial stage of the water supply stage and the clothes wetting stage is configured to sufficiently wet the clothes to prepare a washing stage after the supply water has been completed. The clothes wetting stage can be implemented after or before completing the water supply.

The detergent used in the wool program may be a neutral detergent and, in general, a type of liquid that may not require much time to dissolve in the wash water as a type of powder. Taking into account that, the detergent is supplied to the clothes in the initial stage of the water supply, together with the washing water. Once the water supply starts, wash water is supplied to the liquid detergent contained in a detergent box. The wash water and the liquid detergent are supplied together to the tub or drum. To supply the washing water and the liquid detergent to the clothes more quickly, the washing water and the liquid detergent mixed together can be sprayed onto the clothes in the drum. For the most effective detergent solution, a circulation stage configured to supply the wash water contained in the tank to the top of the drum can be implemented.

The drum can be operated in the oscillation movement and then a soft vortex is generated in the wash water in such a way that the detergent solution can be promoted, while simultaneously preventing damage to the clothes. Once the water supply is completed, the oscillation movement and the circulation stage can be implemented together to prepare for the washing stage. This can be considered as a type of clothing wetting stage.

Once the stage of promoting the detergent solution and the clothes wetting stage has been completed, a heating stage (S1841) configured to heat the wash water can be implemented if necessary. However, the temperature of the wash water in the heating stage can be controlled not to exceed 40 ° C. The heat generated if the temperature of the wash water is intensified too much will deform the clothes and damage the woven woolen clothes. The temperature of 40 ° C does not generate thermal deformity and promotes the activation of the detergent and the absorption of the washing water in the clothes.

A drum drive movement of the washing stage (S1842) may be the oscillating movement. The washing stage requires the longest time of the washing cycle stages and, in order to avoid damage to the laundry in the washing stage, the oscillation movement is used in the washing stage. If the application of mechanical force and stop are applied to woolen fabric clothing repeatedly, damage to the fabric may occur. Such mechanical repetition generates the contraction of the wool fabric. To avoid contraction, the oscillation movement can be implemented in the washing stage continuously.

As mentioned above, the oscillation movement drives the drum by rheostatic braking and may not apply much load to the motor. In addition, the oscillation movement may have a drum drive configured to alternately move to the right and left at less than 90

° C. As a result, a large load is not required to lift clothes. If the drum is operated in the rubbing movement and the progressive movement continuously, an excessive load can be applied to the motor. In the turning movement, a smaller load can be applied to the motor than in the rubbing movement and the progressive movement, but the clothes are raised and lowered causing damage to the fabric. With this in mind, the oscillation movement is implemented in the washing stage.

J.2 Rinse cycle (S1850):

Once the wash cycle has been completed, a rinse cycle can be implemented. First, an intermediate spin can be implemented. After intermediate centrifugation, the wash water is supplied to begin washing and the washing cycle is performed several times if necessary. That is, after the water supply and rinse, the water drain can be repeated. Normally, intermediate centrifugation is implemented at half of the water supply after the water drain.

Intermediate spinning unravels clothes at a relatively low spin speed. The intermediate spin includes an intermediate spin configured to unravel the clothes at a relatively low spin speed, while detecting vibration, and a main spin configured to spin the clothes at a relatively high spin speed for a predetermined time. The intermediate centrifuge can be implemented at approximately 100 RPM and the main centrifuge can be implemented at approximately 200 RPM (low resonance frequency) or more.

However, when the wool program is selected, the intermediate spin can be skipped. Intermediate spinning is a procedure of discharging laundry water from clothes by centrifugal force and a tensile force can inevitably be generated in clothing. Because of that, woven woven clothing that is subjected to an external force may be subject to damage in the spin cycle. To alleviate this concern, intermediate centrifugation can be omitted. For example, the main spin of the intermediate spin is skipped and only the intermediate spin can be implemented. If the entire procedure for discharging the wash water by centrifugal force is omitted, the rinse capacity can be markedly impaired. Taking into account rinse capacity and damage to clothing, only the intermediate spin can be implemented and the main spin can be skipped.

The series of the rinsing stage including the water supply and drainage can be implemented three times or more, since the remains of detergents have to be sufficiently discharged from the clothes. The rinse water level may be higher than the wash stage water level and a circulation stage can be implemented in the rinse. When liquid detergent is used, it is generally possible to discharge the detergent residue sufficiently due to the rinse stage being implemented twice and the intermediate spin. However, in the case of this program, the main spin of the intermediate spin is omitted to avoid damage to the clothes and the rinse stage can be implemented three times to achieve the desired rinse effect.

A drum drive of the rinse stage may be the oscillating movement to prevent damage to the clothes. The oscillation movement gently swings the clothes in the wash water and allows the remains of detergent absorbed in the clothes to be discharged into the wash water, so that the rinse efficiency can be improved.

J. 3 Cycle (S1870) spin:

Once the wash cycle has been completed, a spin cycle can begin. The spin cycle is similar to the spin cycle of the standard program described above. The drum RPM of the normal spin stage can be set to be 800 RPM or less to protect woolen clothing.

K. Program K (delicate program):

A washing program provided according to the type of fabric of the clothing may include a delicate program as shown in Figure 19 for washing laundry items made of delicate fabrics such as silk, plastic cloth, clothing items that have metal accessories attached to them and other delicate items. A drum movement having a relatively weak mechanical force, for example, the oscillating movement, can be implemented to gently wash delicate clothes in the delicate program, similar to the wool program. As a result, having the characteristics of the delicate fabric in consideration, the movements of the drum drive of a wash cycle, a rinse cycle, and a spin cycle of the delicate program may be different from the drum drive movements of the standard program.

K.1 Washing cycle (S1930):

Similar to the wool program, the delicate cycle (S1910) is selected and the drum is actuated in the oscillation movement in a washing cycle (S1930) of the delicate program and the washing water is supplied (S1933) at a level of relatively high water. In addition, a step (S1935) of promoting detergent dissolution may be similar to the step of promoting detergent dissolution of the Wool Program, due to the type of liquid detergent that

10

fifteen

twenty

25

30

35

55

It is generally used to wash delicate clothing items in the delicate program, as in the wool program. However, after the stage of promoting detergent dissolution, a stage (S1936) of wetting clothes may be different from the stage of wetting clothes of the Wool Program. Wool fabric has a relatively good water absorption capacity compared to delicate fabric, and delicate fabric is more subject to heat damage compared to wool fabric. Because of that, the temperature of the wash water used to wash the delicate tissue can be set to be approximately 30 ° C. Although cold water could be selected, a temperature above 40 ° C is generally not selected.

Clothes wetting can be implemented effectively using the filtration movement in the clothes wetting stage. A circulation stage can also be implemented. After actuating the centrifugation of the drum and distributing the clothes evenly inside the drum to expand the area of the surface of the clothes, the circulation stage circulates the washing water contained in the tank towards the clothes. In addition, the oscillation movement is implemented to immerse the clothes in the wash water and to generate the gentle movement of the clothes to promote the wetting of the clothes. The filtration movement and the oscillation movement are repeated in various patterns to promote the wetting of clothes. However, the drum drive movement of the clothes wetting stage may be only the swing movement.

Once the wetting of the clothes is complete, a washing step can begin (S1942). A drum movement of the washing stage may be the oscillating movement. Delicate fabric may be more resistant to external impact, compared to wool fabric. To achieve a more efficient washing efficiency, the drum movement of the washing stage can be a combination of the oscillation movement and the turning movement, with a relatively high level of washing water.

Alternatively, only the flipping movement can be implemented in the washing stage. In this case, the fall clothes collide with the surface of the wash water, not against the inner bottom surface of the drum due to the high level of water. That means the fall distance is reduced. While the impact applied to clothing is reduced by the high level of water, a vortex is generated in the wash water to improve the washing effect. Since such clothing has a relatively low contamination, the washing stage time can be adjusted to be relatively short and the net acting ratio can be set to be relatively low. Although only the flipping movement is implemented, it is possible to avoid damage to clothing. A circulation stage can also be implemented in the washing stage.

K.2 Cycle (S1950) cleared:

Once the wash cycle is complete, a rinse cycle can begin. As mentioned above, the liquid type detergent can be used in the delicate program and the detergent residues can be sufficiently discharged by the rinse stage implemented twice. Like the wool program, an intermediate spin can be omitted in the delicate program. For example, an intermediate spin is not skipped and only a main spin can be skipped. A drum movement of the rinse cycle may be only the flipping movement. Such the flipping movement has the effect of distributing the clothes. That is, the flipping movement allows the surface area of the clothes to come in contact with the wash water evenly and discharge the detergent residue out. In this case, a wash water level can be relatively high. The oscillation movement can be added to the flipping movement in the rinse cycle.

K. 3 Cycle (S1970) spin:

Once the wash cycle has been completed, a spin cycle can begin. The spin cycle of this program may be similar to the wool cycle. The drum RPM of a normal spin stage can be set not to exceed 800 RPM. The delicate fabric has a low percentage of water content / absorption and the wash water can be sufficiently discharged even when the drum is rotated at a relatively low RPM in the normal spin stage. In addition, normal centrifugation can be implemented at a relatively low RPM to avoid damaging the spin-generated tissue.

L. Program L (sportswear program):

A sportswear program shown in Figure 2D can be provided in the laundry program categorized based on the type of fabric of the clothing described below. The sportswear program can be provided for washing clothes of functional fabric that have a good air permeability function and good perspiration absorption such as mountaineering clothing, jogging clothes and sportswear. Like the wool program or delicate program, a drum movement that has a weak mechanical force, for example, the swing movement, can be implemented in the sportswear program. Because, taking into account the characteristics of the sportswear, the drum movements of the wash, rinse and spin cycles provided in the sportswear program may be different from the drum movements of the standard program. Once the cycle (S2010) of sportswear, the wash cycle (S2030), the rinse cycle (S2050) and the spin cycle (S2070) can be implemented as the wool program and the delicate program. However, due to the

5

twenty

25

30

35

40

55

characteristics of sportswear, the washing cycle of the sportswear program may be different from the washing cycle of the other programs described above.

L.1 Washing cycle (S2030):

Sportswear has hydrophobic characteristics that prevent moisture from easily entering tissue. As a result, compared to other types of fabrics, the sportswear fabric has a low percentage of water content / absorption and therefore the water can be supplied to the sportswear fabric sufficiently and continuously in the wash cycle. . For this, a drum drive movement of the wash cycle (S2030), especially a water supply stage (S2033) provided in the wash cycle, may be different from the drum movement of the wash cycle in the other programs .

First, in this program, a one-stage drum drive movement (S2035) of promoting detergent dissolution may be the rubbing movement and / or the progressive movement. The sportswear fabric has little concern about tissue damage, compared to wool or delicate fabrics, so the sportswear program can use the drum drive movement capable of applying a stronger mechanical force than the movement of oscillation

A stage (S2036) of wetting clothes of the sportswear program may be different from the wool cycle and the delicate program. Although it can prevent damage to clothing, the oscillation movement does not provide enough washing water to a folded portion of the clothing due to the hydrophobic characteristics of the sportswear fabric. With this in mind, the filtration movement (including a circulation stage) can be implemented in the clothing wetting stage of the sportswear program. The filtration movement distributes the clothes contained in the drum evenly and supplies the washing water to the clothes evenly. Together with the filtration movement, the turning movement configured to dump clothes continuously can be implemented.

L.2 Rinse cycle (S2050):

A rinse cycle of this program may be similar to the rinse cycles of the standard program, the wool program and the delicate program, and therefore a more detailed description thereof will be omitted.

L. 3 Cycle (S2070) spin:

A spin cycle of this program may be similar to the spin cycles of the standard program, the wool program and the delicate program, and therefore a more detailed description thereof will be omitted.

M. Program M:

In the washing machine according to the second embodiment described above with respect to Figure 2, the tank is fixed directly to the box and the drum is provided in the tank. According to the second embodiment, the tank is fixed and only the drum vibrates. As a result, it is important to prevent the drum from coming into contact with the tank when the drum is rotated and the distance between the bowl and the drum can be greater than the distance in the washing machine according to the first embodiment shown in the Figure one.

When the distance between the tank and the drum is large, the clothes loaded in the drum may not be sufficiently wetted by the washing water supplied inside the tank. Because, when the water is supplied in the washing machine according to the second embodiment, a circulation pump is put into operation to wet the clothes effectively and the washing water supplied to the drum can be circulated. For example, the circulation pump can be operated continuously or operated at a predetermined interval, with the water supply valve being open.

In the washing machine according to the second embodiment, the drum is connected to the back 230 of the tank. However, the back 230 of the tank is supported by the suspension unit through the bearing housing 400, and not by the tank. Because, compared to the washing machine according to the first embodiment that includes the back of the tank directly connected to the tank to support the drum load, the degree of freedom of the drum provided in the washing machine according to with the first embodiment it can be relatively large and the front portion of the drum can have a greater degree of freedom.

However, when the water is supplied to the tank, a water supply line and a circulation line are used to supply the wash water from the front portion of the tank. As a result, the clothes found in the front portion of the drum would be moistened first and the load on the front portion of the drum is greater than the load on the rear portion. This can cause the front portion of the drum to move down. If the front portion of the drum moves down, noise and vibration can be increased during drum rotation and can cause the drum to contact the inner surface of the bowl. As a result, in the washing machine according to the second embodiment, the clothes that are in the front portion and in the rear portion of the drum must be wet evenly when water is supplied to the clothes. Program M is referred to as a washing program applicable to the washing machine according to the second embodiment,

specifically, a standard program of the washing machine according to the second embodiment. This program will be described with reference to Figure 21.

M.1 Washing cycle (S2130):

Figure 21 is a flow chart of the program M. Once the user selects this cycle in the cycle selection part (S2110), the control part can implement the following series of procedures.

The washing cycle may include a stage (S2131) for determining the amount of clothing, a stage (S2133) for water supply, a stage (S2135) for wetting clothes, a stage (S2137) for heating and a stage ( S2139) of rinse. In the following description, the clothes wetting stage is described as an independent stage separate from the water supply stage. However, the clothes wetting stage can be included in the water supply stage.

M.1.1 Water supply (S2133):

After detecting the amount of laundry in the wash cycle, a water supply stage can begin. A clothing determination stage of the water supply stage is described in detail in the previous programs and therefore a more detailed description thereof will be omitted.

The control part supplies wash water to the interior of the tank in the water supply stage. Specifically, the control part opens the water supply valve to supply wash water to the tank through the water supply line and the detergent box. As follows, when the washing water is supplied to the laundry in the washing machine according to the second embodiment, the embodiments of water supply procedures capable of moistening the laundry found in the front portion and the rear portion of the Drum will be uniformly described.

According to a water supply procedure according to a first embodiment, when the water supply stage supplies water, the circulation pump is put into operation to circulate the wash water and the drum is put into operation in a manner simultaneous. The control part can drive the drum in the rubbing movement of the drum movements described above.

In the washing machine according to the second embodiment, the distance between the drum and the tank is larger than the distance between the tank and the drum in the first embodiment. Therefore, in the second embodiment, if the drum is actuated in the turning movement (as in the first embodiment) during the water supply stage, the clothes that are in the rear portion of the drum are not moistened uniformly . That is, since the space between the drum and the tank is larger, the wash water between the drum and the tank cannot be raised by the rotation of the drum in the turning movement and especially, the clothes that are in the Rear portion of the drum does not get wet.

As a result, at the water supply stage of this program, the rubbing movement is implemented instead of the flipping movement. As mentioned above, the rubbing movement rotates the drum at a higher RPM (as compared to the flipping movement), and the wash water between the drum and the tank can be raised by rotating the drum and then drop in clothes.

In particular, if the rear portion of the drum and the tank are tilted downwards in the washing machine according to the second embodiment, the washing water that is in the rear portion of the tank can be supplied to the surface of the clothes for the rubbing movement. The rubbing movement rotates the drum clockwise / counterclockwise, reversing the direction of rotation suddenly. As a result, the sudden inverted rotation of the drum generates a vortex in the wash water and the clothes found in the front and rear portions of the drum can be wetted evenly.

When the water supply valve opens to supply the wash water, the drum is operated and rotated and the clothes move inside the drum according to the drum drive. In this case, the wash water supplied through the water supply line connected to the front portion of the drum can be supplied mostly to clothes that move to the front potion of the drum. The clothes located on the front portion of the drum are moistened before, compared to the clothes found on the rear portion of the drum. As a result, according to the second embodiment of the water supply process, the drum may not be operated until a predetermined time passes after opening the water supply valve for the water supply, or until the water level reaches a predetermined level When the drum is not operated during the predetermined time or until the washing water reaches the predetermined level, the washing water supplied through the water supply line can be kept in the lower part of the tank. The predetermined water level can be determined in consideration of the space between the tank and the drum and the predetermined time can be determined according to the capacity of the tank and the drum and the quantity of the clothes.

In particular, if the rear portion of the tank provided in the washing machine according to the second embodiment is tilted downwards, the washing water can both be collected in the rear portion of the tank. Therefore, after a predetermined time passes, the drum is operated and rotated and the wash water

55

contained in the back of the tank can moisten the clothes that are in the rear portion of the drum evenly. When the drum is operated in the washing machine according to the second embodiment, a drum movement may be the turning movement or the rubbing movement.

When the water supply valve is opened for the water supply according to the second embodiment, without the drum drive, the connection / disconnection of the water supply valve can be controlled. That is, when the water supply valve is opened to supply the water, the wash water may have a predetermined pressure due to the pressure of an external water supply source, such as a tap and then the supplied wash water. along the water supply line, the front portion of the drum can be supplied by the pressure of the water, so that the clothes in the front portion of the drum can be moistened before.

As a result, during the water supply in the second embodiment, the water supply valve is controlled several times to connect and disconnect, be continuously open, and then the supplied wash water can be controlled to connect and disconnect to have a predetermined water pressure enough not to be supplied directly to the drum. Sufficient pressure not to be supplied directly to the drum means a water pressure that allows the water supplied through the water supply line to fall along the drum, the vat or the door is collected in the lower portion of the Cuba, it is not sprayed into the drum directly. The water that falls along the drum, the tank or the door can be collected in the rear portion of the tank and the description of the washing water collected in the tank is similar to the second embodiment, such that a repeated description It can be omitted.

When the clothes contained in the drum become entangled during the water supply stage, the clothes can be partially moistened. In particular, the clothes that are in a center of a mass of tangled clothes cannot be moistened and only the clothes that are on a surface of the dough can be moistened. If only part of the clothing becomes wet, washing cannot be implemented in the washing cycle and a washing capacity can deteriorate. As a result, the control part can actuate the drum in the filtration movement to wet the clothes evenly if the clothes become entangled.

That is, the control part opens the water supply valve to supply water and actuate the circulation pump to circulate the wash water simultaneously. In addition, the control part rotates the drum at a predetermined RPM. The predetermined RPM is determined as an RPM that allows garments not to fall by gravity, but to be in close contact with the inner surface of the drum during drum rotation. As a result, the predetermined RPM can be adjusted for the centrifugal force generated by the rotation of the drum to be greater than the acceleration of gravity when the drum is rotated. In addition, the predetermined RPM can be set to be less than an area of excessive speed (approximately 200 RPM to 35 RPM) that generates resonance in the washing machine. If the drum is rotated at an RPM higher than that of the excessive speed area, noise and vibration can be markedly increased by resonance. As a result, the default RPM can be set to be approximately 100 RPM to 170 RPM in this control procedure.

As a result, once the control part rotates the drum at the predetermined RPM, the clothing may be in close contact with the inner surface of the drum due to centrifugal force. The wash water supplied through the circulation line and the water supply line can be distributed along the rotation of the drum. Distributed washing water can be supplied to the drum and clothes in close contact with the inner surface of the drum, so that the clothes can be wetted evenly.

M.1.2 Wetting (S2135) of clothing:

After the water supply stage, the control part can start a clothes wetting stage. In the clothes wetting stage, the control part disconnects the water supply valve. The control part drives the drum and the wash water is circulated, while the circulation pump is operated. Although the wetting of clothes is implemented in the water supply stage, the water supply valve is disconnected in the clothes wetting stage and the wetting of the clothes can be implemented by the drum drive.

In the wetting stage of this program, the control part drives the drum to implement the wetting of the laundry. In this case, the control part can drive the drum in the turning movement. Since the turning movement moves the contained clothing by rotating it in the drum together with the rotation of the drum, the washing water comes into contact with the clothes frequently and the wetting of the clothes can be implemented without problems.

When the clothes wetting stage is implemented, the control part classifies the clothes wetting stage into first and second clothes wetting stages. The first and second stages of wetting clothes can be operated according to the drum movements of the drum / that is, the control part can control the movements of the drum of the first and second stages of wetting clothes to be different from each other. . The operation of the circulation pump is as follows.

5

10

25

30

35

40

Four. Five

55

Specifically, in the first stage of wetting clothes, the control part can actuate the drum in one of the rotational and / or progressive movements. The selection of drum drive movements can be determined according to the amount of clothing. That is, if the amount of the clothes contained in the drum is less than a predetermined reference value, for example, if the amount of clothes is small, the control part can operate the drum according to the progressive movement. If the amount of clothing is the reference value or more, the control part can operate the drum according to the turning movement.

As mentioned above, if the amount of clothing is small, the effect of falling clothes from the progressive movement can be improved. As a result, if the amount of clothing is small in the first stage of wetting clothes, the progressive movement drops the clothes with a maximum drop distance to allow water to be absorbed into the clothes. Meanwhile, if the amount of clothing is large in the first stage of wetting clothes, the spinning movement is implemented. This is because the falling distance of the clothes of the progressive movement is not relatively large in the case of a large amount of the clothes.

Therefore, in the second stage of wetting clothes, the control part can drive the drum at a predetermined RPM allowing the clothes to be in close contact with the inner surface of the drum, it does not fall by gravity, i.e. according With the filtration movement. Finally, the drum is rotated at the predetermined RPM and the clothing may be in close contact with the inner surface of the drum due to centrifugal force. The wash water supplied by the circulation pump is supplied to the clothes attached to the inner surface of the drum in a uniform manner and therefore the clothes can be wetted evenly.

In the second stage of wetting clothes, the control part may implement another drum drive movement after the filtration movement. For example, the control part may implement the turning movement after the filtration movement. In this case, the filtration movement distributes the clothes to supply the washing water to the clothes and the turning movement moves the clothes by rotating it to moisten the clothes in the washing water evenly.

M.1.3 Heating (S2137):

After that, the control part starts a heating stage. Specifically, the control part drives the drum in accordance with one of the turning and / or turning and / or oscillating movements in the heating stage, with the actuation of the heater provided in the tank to heat the washing water contained in the Cuba

In the washing machine of the second embodiment, the space between the drum and the tank is greater than the space of the first embodiment. Because, when the washing water is heated by actuating the heater, the drum is rotated and only the washing water contained in the tank is heated, not the washing water contained in the drum. As a result, compared to hot wash water, contaminants in clothing may not be removed without problems at a washing stage, which will be described later, due to the relatively low temperature of the laundry.

Because of that, the control procedure applied to the washing machine according to the second embodiment drives the circulation pump in the heating stage, to circulate the washing water. The hot wash water kept in the tank is supplied back to the upper portion of the tank by the circulation pump so that the clothes can be heated. However, in the heating stage, the circulation pump can be operated intermittently at a predetermined interval, not operated continuously. In particular, in the heating stage, the circulation pump can be controlled so that the disconnection time of the circulation pump is longer than the connection time. If the circulation pump is operated continuously in the heating stage or if the connection time of the circulation pump is longer than the disconnection time, the washing water not heated to the predetermined temperature would be recirculated and the Washing water cannot be heated to the desired temperature.

If the heater is provided in the tank, it is important to operate the heater when it is not exposed outside the surface of the water. If the heater is operated while exposed, excess load is applied to the engine and the heater may malfunction. As a result, if the heater is operated in the heating stage, a predetermined water level distant from the heater (hereinafter, the reference water level) can be maintained in the heating stage. That is, when the water level is lower than a reference level in the heating stage, the control part disconnects the heater. When the water level increases to the predetermined level or more by the new water supply, the control part connects the heater again (hereinafter, 'interruption').

However, if the heating stage uses the interruption procedure in the washing machine according to the second embodiment, the excess load can be applied to the heater and a variety of circuits and the life of the washing machine can be seen reduced

That is, the heating stage of the washing machine according to the second embodiment drives and heats the heater, while a circulation pump is operated at the same time as mentioned above. As a result, the level of water inside the tank cannot be maintained regularly by the circulation pump drive, but can be varied to a predetermined degree of shape.

keep going. In this case, the water level inside the tank is varied enough to be reduced below the reference water level. Especially, if the water level inside the tank is varied beyond the reference level, the heater can be switched on if the water level is above the reference level and disconnected if the water level is below the value reference, so that the motor connection / disconnection can be repeated continuously. Repeated heater connection / disconnection may apply too much load to the heater and the variety of circuits and may reduce the service life.

As a result, if the water level inside the tank is reduced to reach the reference level during the motor drive in the heating stage of the washing machine according to the second embodiment, a new water supply can be implemented. to avoid repeated heater on / off. Specifically, when the water level inside the tank is reduced below the reference level in the heating stage, the control part stops the drum drive and disconnects the circulation pump. At this time, in addition, the water supply valve opens to implement a new water supply. The reason why the drum and the circulation pump are disconnected is that it is difficult to detect a precise water level due to the variation of the water level when the drum and the circulation pump are operated. By extension, it is possible to turn off the engine. Meanwhile, a new water supply can be implemented for a predetermined time or until the water supply is implemented so that the water level reaches the reference level or beyond the reference level by the water level sensor. A specific water level of the new water supply can be differentiated according to the type of program selected in the initial heating stage.

M.1.3 Washing (S2139):

After the heating stage, the control part can implement a washing stage configured to operate the circulation pump, while the drum is operated. In the washing stage, a drum drum drive movement can be suitably selected from the drum moves according to the program selected by the user. For example, a drum drive movement of the washing stage can be determined, similar to one of the washing steps provided in the previous programs. The circulation pump can be operated at a predetermined interval to circulate the wash water contained in the tank.

M.2 Cycle (S2150) cleared:

Once the wash cycle is completed after the previous steps, the control part can start a rinse cycle. The rinse cycle may generally include a rinse-spin stage, a water supply stage, a drum drive stage and a water drain stage. First, the control part starts the rinse-spin, rotates the drum at a second speed (RPM 2) (S2151), in the rinse-spin stage, to remove any remaining moisture and detergent residue on clothes, while rotating the drum at approximately 500 RPM to 700 RPM. The control part stops the drum and opens the water supply valve, to supply rinse water to the tank. The rinse water level can be determined according to the program selected by the user or according to the user's manual configuration.

After the water supply, the control part drives the drum at a first rotational speed (RPM 1) at a predetermined interval. In the drum drive stage, the control part controls a drum drum drive movement and removes laundry detergent. The control part of this stage can control the drum to be one of the turning and / or progressive movement and / or rubbing and / or turning and / or oscillation described above.

Therefore, the control part stops the drum drive and drives the water drain pump to drain the rinse water contained in the tank outwards (S2153).

The rinse-spin cycle, the water supply stage, the water supply stage, the drum drive stage and the drain stage described above can compose a single cycle of the rinse cycle. The control part can implement the cycle once or several times according to the selected program or the user's selection. However, the Individual rinse cycle program may include the rinse-spin stage. The second spin speed of the rinse-spin stage may correspond to approximately 500 RPM to 700 RPM, as mentioned above, and the spin speed of the rinse-spin may correspond to the excess speed area (about 200 RPM at 350 RPM) that generates resonance of the washing machine.

As a result, if the laundry found in the drum is not distributed evenly, a washing distribution stage configured to distribute the laundry can be implemented and after that, the drum speed can be accelerated for rinsing-spinning. The washing distribution stage repeatedly rotates the drum at the predetermined RPM clockwise and / or counterclockwise. After the washing distribution stage, a level of eccentricity of the drum is identified. The eccentricity level of the drum is lower than a predetermined value, the rinse-spin can be implemented. If the eccentricity level is the value

By default or more, the washing distribution stage can be repeated. Since the wash distribution stage is performed before the rinse-spin stage, the rinse cycle time can be increased. In particular, since the clothing distribution stage is repeated, the rinsing cycle time can be markedly increased and the time consumed by the rinsing cycle cannot be accurately predicted.

As follows, to solve the above problem, a rinse cycle control procedure capable of reducing the total time consumed by the rinse cycle will be described.

As shown in Figure 21, the rinse cycle of the washing machine according to the second embodiment may include a stage for supplying wash water, a stage (S2151) for drum operation and a stage (S2153) for drainage of water. In comparison with the first embodiment, the rinse cycle according to the second embodiment omits a rinse-spin stage. Since the rinse-spin cycle has been omitted, the rinse cycle time may be reduced as much as the rinse-centrifuge stage time and the wash distribution stage may not be necessary, thus significantly avoiding an increase in time. of the rinse cycle caused by the repetition of the clothing distribution stage. Although the omission of the rinse-spin stage reduces the rinse cycle time, the rinse-spin stage configured to remove detergent residues by rotating clothes at a relatively high speed is omitted and then it would be difficult to eliminate enough detergent residue.

As a result, in the rinse cycle control procedure according to the second embodiment, the drum is rotated at the second rotational speed (RPM 2) for approximately 1 to 3 minutes, and does not stop at the drain stage of water. The second speed of rotation is determined to be a predetermined speed that allows the clothes to be fixed to the inner surface of the drum due to gravity, and not to fall, during the rotation of the drum. The second speed of rotation can be adjusted so that the centrifugal force generated by the rotation of the drum is greater than the acceleration of gravity. In addition, the second turning speed can be set to be less than the excess speed area of the washing machine. If the drum is rotated over the area of excess speed, resonance can increase noise and vibration noticeably. As a result, the second turning speed can be set at approximately 100 to 170 RPM.

Finally, the drain stage rotates the drum at the predetermined speed and therefore the clothes may be in close contact with the inner surface of the drum due to centrifugal force in order to remove the laundry detergent residue. Compensating for the omission of the rinse-spin stage, the drain stage rotates the drum at the second rotation speed to avoid deterioration of the rinse capacity.

In the stage of rotating the drum at the second turning speed (the predetermined speed that allows the clothes to be in close contact with the inner surface of the drum), if the water contained in the tank is drained, all of the Drainage stages can be implemented before the rinse cycle. That is, even if the water is drained in the wash cycle, the stage of rotating the drum at the predetermined RPM can be implemented.

M. 3 Cycle (S2170) spin:

A spin cycle of this program may be similar to the spin cycles of the other programs, for example, the spin cycle of the program A. Therefore, a further detailed description thereof will be omitted.

The program M described above can be applied to the washing machine according to the second embodiment. However, the M program can also be applied to the washing machine according to the first embodiment. That is, the M program can be applicable to any of the washing machines according to the first and second embodiments.

N. Time management option:

A time management option will be described below. Typically, once a specific program is selected, an operation of the selected program begins based on a preset algorithm and the operation ends in a predetermined period of time. The operating time required to implement the program can be for the total time required by the individual cycles that make up the program. This total operating time can be displayed in the display part 119.

Under certain circumstances, the operation time may be too long. For example, if the user has to exit in 1 hour and the default operating time is 1 hour and 20 minutes, the operating time is 20 minutes longer than is desirable for the user. In contrast, severe contamination can make the washing operation implemented for 1 hour and 20 minutes not enough to wash clothes. To solve the problem, a washing machine and its control procedure capable of managing time are provided.

The washing machines described above may include a time management option provided to manage the time. That is, the operating time of a specific program can be increased or decreased through the options part. Specifically, the user can select a saving option of

5

10

fifteen

twenty

25

30

35

40

Four. Five

fifty

55

Time in time management option. Alternatively, the user can select an intensive option through the time management option. If these options are not selected, the operation can be implemented according to the preset program. This time management selection can be implemented before starting the wash cycle and after selecting the operation program.

For example, when the user selects the time saving option if the operation time of the cotton program is 120 minutes, the required operation time can be reduced to, for example, 100 minutes. When the user selects the intensive option, the operating time can be increased to 140 minutes to ensure sufficient cleaning of highly contaminated clothing. There may be a predetermined difference between the preset time and the time actually required.

The required time of the wash cycle and / or the rinse cycle may vary according to the selection of the time saving option. That is, the Program Whose required operating time is changed / adjusted may be different depending on the selected program. For example, in the case of the cotton program, the synthetic program and the mixed program, it is important to improve the washing capacity. Because of that, the required time of the normal wash cycle cannot be variable, even if the time saving option is selected. Therefore, the required time of one of the components of the rinse cycle can be considered for adjustment.

The rinse cycle repeats the water supply, water discharge and centrifugation. The rinse can be implemented twice, three times or four times. The centrifugation can be implemented in the same order of the spin cycle, with the RPM and the main spin time less than the spin cycle. As a result, when the time-saving option is selected, the main spin cycle rinse can be skipped.

When the time saving option is selected, the step of determining the amount of clothing can be omitted, depending on the selected program. For example, when the wool, delicate or sportswear program is selected, the amount of this special fabric is relatively small. If such textile items become contaminated, the user tends to wash them immediately. As a result, it is rare to wash a large amount of this type of clothing in a single program operation. Taking into account that, the step of determining the quantity of clothing can be omitted when the wool, delicate or sportswear program is selected.

On the contrary, when the intensive option is selected, the number of rinse implementations in the rinse cycle or the necessary wash cycle time can be increased, or both can be increased.

This time management option satisfies the object of the specific program and allows the user to conveniently manage the time.

IV. Drum drive movement with the program and program stage

Next, a drum drive movement will be described according to each cycle of each program. As mentioned above, the drum drive movement includes a combination of the direction of rotation of the drum and the speed of rotation of the drum, and differs from the direction of fall and the point of fall of the clothes found in the drum to compose the different movements of the drum. These drum drive movements can be implemented under motor control.

Since the clothes are lifted by the elevator provided on the inner circumferential surface of the drum during the rotation of the drum, the speed of rotation and the direction of rotation of the drum are controlled to differentiate the impact applied to the clothes. That is, the mechanical force including friction between clothes, friction between dirty clothes and wash water and the impact of falling can be differentiated. In other words, a level of impact or rubbing of the clothes can be differentiated to wash the clothes, and a level of distribution of clothes or a level of clothes turning can be differentiated.

As a result, a drum drive movement can be differentiated according to each cycle that make up the various washing programs and each specific stage that makes up each cycle so that the clothes can be treated by an optimized mechanical force. Because of that, the washing efficiency can be improved. In addition, a single fixed drum drive movement can result in excessive washing time. Next, a drum drive movement will be described for each cycle.

Wash cycle:

A wash cycle includes a stage for determining the amount of clothing, a water supply stage and a washing stage. The water supply stage includes one which stage of promoting the detergent solution configured to dissolve detergent and a clothes wetting stage configured to moisten the clothes. The stage of promoting the detergent solution and the wetting stage clothes can be provided independently, separate from the water supply stage. A heating stage can be additionally provided according to each cycle.

1.1. Determination of the amount of clothing:

The electric currents used to rotate the drum are measured to apply the step of determining the amount of clothing. In this case, when the drum is rotated in a predetermined direction, the currents consumed are measured, and the drum can be operated according to a single flipping movement, for example, the flipping movement, in the step of determining The amount of clothes.

1.2 Water supply:

In a water supply stage, the wash water is supplied together with the detergent and a stage of dissolving the detergent can be implemented. To improve the efficiency of the wash cycle, the detergent solution can be completed effectively at an initial stage of the water supply stage. To dissolve the detergent in the wash water quickly, a movement configured to apply a mechanical force can be effective. That is, a strong mechanical force is applied to the wash water to dissolve the detergent in the wash water more efficiently. As a result, at the stage of promoting the detergent solution, the drum is rotated according to the progressive movement and / or the rubbing movement. As mentioned above, progressive movement and rubbing movement rotate the drum at a relatively high speed, apply a sudden brake to the drum to change directions, and strong mechanical force can be provided. A combination of the progressive movement and the rubbing movement may be possible at this stage.

In the stage of promoting the wetting of clothes, it is important to wet the clothes in the wash water mixed with the detergent. In this case, a drum drive movement may be the filtration movement. Alternatively, the filtration movement and the rotation movement can be implemented sequentially. The turning movement continuously rotates the clothes to allow the washing water contained in the lower part of the drum to come in contact with the clothes in a uniform manner and is suitable for wetting the clothes. The filtration movement widens the clothes during the rotation of the drum to bring the clothes in close contact with the inner circumferential surface of the drum, while the washing water is sprayed in the drum at the same time, such that the washing water is It can discharge from the tank through the clothes and through holes of the drum due to centrifugal force. As a result, the filtration movement expands the surface area of the clothes and allows the wash water to pass through the clothes. Because of this, the effect of supplying the wash water to the clothes evenly can be achieved. In addition, to use such an effect, two different drum drive movements, that is, the filtration movement and the rotation movement are repeated sequentially at the stage of promoting the wetting of clothes. If the amount of clothing is a predetermined value or more, the wetting effect of clothing may deteriorate in the spinning movement that has the relatively low spinning speed of the drum, and therefore the turning motion that has the spinning speed. Relatively high drum can be implemented instead of the turning movement.

However, the stage of promoting detergent dissolution or the clothes wetting stage of the water supply stage can be classified according to the drum drive movement when washing water is continuously supplied. As a result, it is difficult for the user to distinguish the stages described above in the water supply stage. From the user's point of view, it appears that the drum is operated in accordance with one of the turning and / or turning and / or progressive and / or rubbing movements in the water supply stage, or a combination of two or more movements

Depending on the type of clothing fabric, there may be programs configured to prevent damage to the wash cloth. Also, according to the program, there may be programs configured to suppress the generation of noise when the laundry is washed based on the cycles. When the drum is operated in accordance with the movement capable of applying a large mechanical force in the water supply stage, the damage of washing tissue or noise generation can generally be difficult to avoid. As a result, in the water supply stages, movements capable of reducing noise generation as much as possible or preventing tissue damage are provided. In these programs, the detergent dissolution effect and the wetting effect of the clothes are achieved so that, in these programs, the drum can be operated in the oscillating movement or the turning movement time can be increased.

The oscillation movement can minimize the movement of the clothes contained in the drum, in comparison with the other movements, and can minimize the tissue damage caused by the friction of clothes and the friction between the clothes and the drum. In addition, the turning movement induces the turning movement in the clothes along the inner surface of the drum, and does not generate an impact generated by the sudden fall of the clothes.

If the detergent solution and the wetting of the laundry are implemented in the water supply stage, a circulation stage configured to circulate the wash water can be provided in at least one predetermined stage. A circulation stage of this type can be implemented at the water supply stage or at a predetermined stage of the water supply stage.

1.3 Heating:

In a heating stage, a drum drive movement configured to transmit heat

10

twenty

25

40

55

generated while the heater provided in the tank heats the washing water to the clothes can be provided. In the heating stage, the drum is operated in accordance with the turning movement configured to rotate the drum in the predetermined direction continuously. If the direction of rotation of the drum is changed, a vortex is generated in the wash water and the heat transfer efficiency may deteriorate. If the amount of clothes is less than a predetermined level the amount of clothes, the drum is actuated in the turning movement. If the amount of clothing is at the level of the predetermined amount of clothing or more, the drum is actuated in the flipping motion. The spinning movement can heat the clothes sufficiently if the amount of clothes is less than the predetermined level. If the amount of clothing is at the predetermined level or more, the flipping movement configured to rotate the drum at relatively high speed may be appropriate.

1.4 Washing:

A washing step can take the longest time of the washing cycle. In the washing stage, the contaminants in the laundry can be substantially removed and a drum drive movement of the washing stage can be a movement capable of moving the laundry in various patterns. For example, the drum drive movement of the washing stage may be one of, or a combination of, the progressive movement and / or the turning movement and / or the turning movement. Such a combination of movements can apply a strong mechanical force to the clothes. Especially, in the case of a small amount of clothing, a combination of these movements can be effective.

The drum drive movement of the washing stage may be a combination of the filtration movement and the turning movement. Such a drum drive movement can continuously supply washing water to the laundry to improve the washing efficiency and can apply a mechanical force to the laundry evenly to improve the washing efficiency. Such a combination can be effective with a large amount of dirty clothes.

A heating stage is provided before the washing stage and the washing water can be heated in the washing stage to improve the washing efficiency. If the wash water is heated, the drum drive movements can be combined. For example, if the heater provided in the tank is operated to heat the wash water, the drum can be operated in accordance with a drum drive movement without sudden braking.

As mentioned above, in programs configured to prevent tissue damage and to suppress noise generation, a movement capable of applying a relatively weak mechanical force to the clothing can be provided in the washing stage. For example, the washing steps of the previous programs, the oscillation movement can be implemented to reduce noise generation and prevent tissue damage. As a result, the operating time of the swing movement may be longer than the other movements in the program. If the washing step is performed only by the oscillation movement, the washing efficiency can be impaired and a movement having a strong mechanical force can be provided additionally. The operating time of the movement that has the strong mechanical force can be set to be shorter than that of the movement that has the weak mechanical force.

2. Rinse cycle:

In the rinse cycle, the water supply, drum drive and drain stages are repeated to rinse contaminants attached to the laundry or detergent residue. As a result, a drum drive movement of the rinse cycle may be a movement capable of generating an effect similar to rubbing. For example, the driving movement of the rinse cycle drum may be the rubbing movement and / or the oscillating movement. Both the rubbing movement and the oscillating movement have the effect of rubbing and oscillating the clothes in the washing water continuously, to improve the rinse capacity.

When the drum is operated in the rinse cycle, a circulation stage configured to circulate the wash water contained in the tank inside the drum and the filtration movement can be implemented together. That is, the wash water is sprayed in the drum and the clothes are rinsed by the flowing water. The filtration movement generates a strong centrifugal force and can separate detergent and contaminants from clothing, along with washing water.

In the rinse cycle, the wash water can be drained together with bubbles by the use of mechanical force applied to the clothes during the drain and / or intermediate spin. As a result, the drum is actuated in the progressive movement or flipping movement. By dropping the raised clothes, the washing efficiency can be improved and the bubbles can be removed without problems. The movement of the drum can be differentiated depending on the quantity of clothes. That is, in the case of a small amount of clothing, the progressive movement is implemented to generate a maximum distance of fall. In the case of a large amount of clothing, the flipping movement is implemented.

As mentioned above, in the programs selected to avoid any tissue damage or to suppress the generation of noise, the movement capable of applying a relatively weak mechanical force to the clothing can be provided in the rinse cycle. For example, the swing movement can be provided in the

5

10

fifteen

twenty

25

30

35

40

Four. Five

rinse cycles of the programs. In the selected program to reduce the washing time, it is possible to reduce the rinse cycle time. For example, the filtration movement consumes a relatively large amount of time and therefore the filtration movement can be omitted in the drum drive stage of the rinse cycle in the case of a selected program to reduce the total wash time .

3. Spin cycle:

In a spin cycle, the drum is rotated at a predetermined or higher speed to remove moisture contained in the laundry and the spin cycle may include a clothing unraveling stage and an eccentricity measuring stage to accelerate the speed of drum rotation at a predetermined RPM. A suitable drum drive movement can be selected according to the object of each stage. For example, it is advantageous at the stage of unraveling clothes to apply a relatively strong mechanical force to the clothes. If a movement capable of applying a large mechanical force in the pre-rinse cycle is provided, even a movement that has a weak mechanical force is sufficient. In addition, to measure eccentricity accurately, a drum drive movement configured to rotate the drum in one direction continuously may be appropriate in the eccentricity measurement stage.

V. New programs

In the description of the different programs, each program includes a wash cycle, a rinse cycle and a spin cycle. However, it is possible to skip a single cycle of each program according to the user's selection. That is, it is possible to skip the wash cycle of program A (standard program) or skip the rinse cycle of program B (heavy contaminant program) or skip the spin cycle of program C (rapid boil program). By extension, one of the cycles provided in each program can be established as an auxiliary program. For example, the wash cycle of the F program (functional garment program) can be established as a new Individual program. In this case, it can be referred to as 'washing of functional garments'. Instead of the wash cycle, the rinse cycle or the spin cycle provided in each program can be established as a new program.

Although the wash cycle, the rinse cycle and the spin cycle are described in a particular order to explain each of the programs, such cycles of one program can be combined with cycles of another program to establish a new program. For example, the rinse cycle and the spin cycle of program A (standard program) can be combined with the wash cycle of program B (heavy contaminant program) and are defined as a new program. Alternatively, each cycle can be taken from the other programs. For example, the rinse cycle of program A (standard program) and the spin cycle of program M can be combined with the wash cycle of program B (heavy contaminant program) and are defined as a new cycle. In this case, the stages configured to connect the cycles can be adjusted or changed as appropriate.

In addition, a new program can be carried out based on the efforts and conditions of the clothing. Figures 22 to 25 illustrate the stages, effects and conditions used to determine the movements of the standard program, strong movement programs (strong contaminant program, rapid boil program and cold wash program) and weak movement programs (program colored, delicate or wool). Based on the desired effects and conditions, drum movements can be selected interchangeably between standard program, strong movement programs and weak movement programs to create new programs. The present disclosure and features may also be applied to the movement of a dryer drum, which, for example, is disclosed in United States Patent Publications No. 2009/0126222, 2010/0005680 and 2010/0162586.

In accordance with the control method of the present invention as mentioned above, the various movements of the drum are provided and the efficiency of the washing, rinsing and spin cycles can be improved.

In addition, according to the control procedure, the various combinations of drum movements are provided based on the weight of the clothes, type of clothes, type of detergent, degree of dirt and selected program.
