BEST MODE FOR CARRYING OUT THE INVENTION

I. washing machine

The washing machine and its control method as embodied and described in detail in the materials of this application will be described with reference to the accompanying drawings. 1 is an exploded perspective view of a washing machine according to a first embodiment, described in detail herein, to which control methods according to various embodiments can be applied.

With reference to FIG. 1, a washing machine 100 according to a first embodiment includes a housing 110 configured to determine the appearance of the washing machine, a tank 120 provided in the housing 110 for receiving washing water therein, and a rotating drum 130 provided in the tub 120. The cabinet 110 determines the appearance of the washing machine 100. At the opening 114 of the cabinet 110, a door 113 is provided, and the user opens the door 113 to load laundry into the cabinet 110.

In the housing 110, a tank 120 is provided for receiving washing water therein. The drum 130 may house laundry and rotate in the tub 120. In this case, a plurality of jaws 135 may be provided in the drum for lifting and dropping the laundry during washing. The drum 130 includes a plurality of through holes 131 to allow washing water in the tub 120 to pass through them. The tank 120 may be supported by one or more springs provided on the outside of the tank 120. The engine 140 is attached to the rear surface of the tank 120, and the engine 140 rotates the drum 130. When the drum 130, which is rotated by the engine 140, generates vibration, the tank 120 vibrates with the drum 130. When the drum 130 rotates, the vibration generated in the drum 130b and in the tank 120 can be absorbed by the shock absorber located under the tank 120.

As shown in FIG. 1, the tub 120 and the drum 130 may be mounted substantially parallel to the base plate of the housing 110. Alternatively, the rear portions of the tub 120 and the drum 130 may be tilted, with the open portion of the drum 130 pointing slightly upward to enclose the load laundry to the drum 130.

A control panel 115 may be provided at a predetermined end portion of the housing 110. The user can select the washing machine mode or can obtain information related to the washing machine through the control panel 115. For example, a mode selection component 117 may be provided on the control panel 115 so that the user can select a specific washing mode. Additionally, an option selection component 118 may be provided to allow the user to adjust the operating conditions of each cycle or step provided in the selected mode, and a display component 119 may be provided on the control panel 115 to display the current operating information of the washing machine. A washing machine is described in more detail in US Pat. No. 6,460,382 B1, published October 8, 2002, and US Application No. 12 / 704,923, registered February 12, 2010, the full disclosures of which are incorporated herein by reference.

Figure 2 is an exploded perspective view of a washing machine according to another embodiment described in detail in the materials of this application. A washing machine according to various embodiments described in detail in the materials of this application may include a tank fixedly attached to the body, or a tank attached to the body by means of a flexible structure, for example, a suspension unit, due to which it is not fixedly attached to the body, as shown in figure 2. Also, the supporting structure of the tank may be a cross between a suspension unit and a fixed structure. That is, the tank can be supported movably by means of a suspension unit, which will be described later, and it can be supported stationary to be secured in a more stationary state, in contrast to the aforementioned securing in a movable state. In alternative embodiments, a washing machine may be provided without a housing. For example, the installation space of a built-in type washing machine may be determined by the wall structure rather than the housing structure. Those. in certain embodiments, a housing configured to model an individual appearance may not be provided.

With reference to FIG. 2, the tank may include a front part 200 of the tank and a rear part 220 of the tank. The front part 200 of the tank and the rear part 220 of the tank can be combined with bolts or other suitable mounting mechanism, while a predetermined space is formed inside the tank for accommodating the drum. The rear portion 220 of the tank includes an opening formed on its rear surface, while the rear gasket 250 may be connected to the inner circumference of the opening. The rear gasket 250 may be connected to the rear wall 230 of the tank, and the rear wall 230 of the tank may include a through hole, and a shaft passes through the center of the hole.

The rear gasket 250 is connected to both the rear wall 230 of the tank and the rear 220 of the tank for sealing, to prevent leakage of water from the washing tank. Since the rear wall 230 of the tank vibrates when the drum rotates, the rear wall 230 of the tank may be removed from the rear of the tank 220 and may not come into contact with the rear of the tank 220. In this case, the rear gasket 250 may be formed of a flexible material to allow relative movement of the rear wall 230 of the tank without contacting the rear part 220 of the tank. The rear gasket 250 may include a corrugated portion that expands sufficiently to allow for relative movement of the rear 230 wall of the tank. This embodiment provides a rear gasket 250 connected to the rear wall 230 of the tank, but the present invention is not limited to this. The rear gasket 250 is configured to seal the gap between the tank and the drive portion (not shown) including the shaft 351, the bearing housing 400, and also to allow relative movement of the drive portion in relation to the tank. Thus, the shapes of the rear gasket 250 and the connected objects can be changed without limitation, but only if the mentioned function is provided. Flexible material 280, which will be described as a front gasket, can be mounted on the front portion of the front wall 200.

The drum may be configured from the front wall 300 of the drum, the Central part 320 of the drum and the rear wall 340 of the drum. At the front and rear portions of the drum, respectively, ball balancers 310 and 330 can be mounted. The rear wall 340 of the drum can be connected to a star-shaped part 350, which can be connected to the shaft 351. The drum rotates in the tank due to the rotational force transmitted by the shaft 351.

The shaft 351 can be connected to the engine and passes through the rear wall 230 of the tank. In some embodiments, an engine may be connected concentrically to shaft 351. In some embodiments, the engine may be directly connected to the shaft 351, and in particular, the rotor of the engine may be directly connected to the shaft 351. In alternative embodiments, the engine and shaft 351 may not be directly connected to each other, for example, they may be connected with a belt.

A bearing housing 400 may be attached to the rear wall of the tank 230 between the engine and the rear wall of the tank 230 so as to rotate to support the shaft. The stator may be fixedly mounted to the bearing housing 400. The rotor may be located around the stator. As mentioned above, the rotor can be directly connected to the shaft 351, the engine being an external rotor motor that can be connected directly to the shaft. Bearing housing 400 may be supported by base 600 via a suspension unit. The suspension unit may include a perpendicular suspension device and an inclined suspension device configured to support the bearing housing 400 in a forward and reverse direction. For example, the suspension unit according to this embodiment may include three perpendicular (vertical, as shown in FIG. 2) suspension devices 500, 510 and 520 and two inclined (angled or inclined, as shown in FIG. 2) devices 450 and 530 for suspension, configured to support the bearing housing 400 with respect to the back and forth direction. The suspension unit may be connected to the base 600 by a predetermined flexible transformation, allowing the drum to move forward / backward and to the right / left, and thus the connection is not stationary. Those. the suspension unit may be supported by the base with satisfactory predetermined flexibility to allow rotation by a predetermined angle in the forward / backward and right / left directions with respect to points connected to the base. To provide such flexible support, a perpendicular suspension device may be installed on the base, if necessary, by means of a rubber sleeve or other mechanism.

The perpendicular device for hanging the suspension unit can spring-stop the vibration of the drum, and the inclined device for hanging can dampen the vibration. Those. a perpendicular suspension device can be used as a spring, and an inclined suspension device as a damping means, in a vibration system including a spring and a damping means.

The tank is supported by the housing, and the vibration of the drum can be suppressed by means of a suspension unit. As a result, the washing machine according to this embodiment may have a substantially independent support structure between the tub and the drum, or it may have a structure in which vibration of the drum is indirectly transmitted to the tub.

II. DRUM ROTATION MOVEMENT

The variety of drive motions of the drum and their combinations, as embodied and described in detail in the materials of this application, can provide significant improvements for washing, noise / vibration, energy consumption and user satisfaction. A control method that provides improved washing ability will be described. The effect of hand washing can be embodied in various patterns of movement of linen. For example, the effect of hand washing can be embodied by a combination of kneading and / or unraveling and / or stress and / or swing and / or friction and / or saturation / saturation with compression.

Such various patterns of movement of the linen can be implemented by various drive motions of the drum and a combination (and) of various drive motions of the drum. Drum driving movements may include a combination of rotation directions and drum rotation speeds. The laundry placed in the drum, depending on the driving movements of the drum may have different directions of falling, points of falling and height of falling. For this reason, the laundry can be moved inside the drum in different ways. The driving movements of the drum can be implemented, for example, by controlling the direction of rotation and / or the speed of the engine that drives the drum.

When the drum rotates, the laundry is lifted by one or more jaws 135 provided on the inner circumferential surface of the drum. For this reason, it is possible to control the direction of rotation of the drum, while the impact applied to the laundry can be changed accordingly. Those. the mechanical effect applied to the laundry can be changed, for example, the friction formed between the laundry items, the friction formed between the laundry and water and the impact due to dropping the laundry. In other words, the impact force and friction applied to the laundry items may change, and the degree of distribution or the intensity of turning the laundry inside the drum may change accordingly.

As a result, such a control method of the washing machine may include various drive movements of the drum, and the drive movements of the drum are changed in accordance with the cycles and the specific steps constituting the cycle, so that the optimum mechanical effect for washing the laundry, depending on the type of laundry to be washed, degree of pollution and other similar factors. For this reason, the washing efficiency of the laundry can be improved. In addition, you can get rid of the excessive time that is required with a typical driving movement of the drum.

In specific embodiments, for implementing such various driving motions of the drum, engine 140 may be a direct-coupled motor. Those. the engine may have a stator attached to the rear surface of the tank 120, and a rotor that directly rotates the drum 120. Due to the fact that it becomes possible to control the direction of rotation and torque of the engine with a direct connection type, it is possible to prevent a time delay or a reverse stroke, and in this case, it is possible to properly control the driving movement of the drum.

In contrast, drive movements of the drum allowing a time delay or a reverse stroke, for example, a flipping or rotating motion, may be embodied by an indirect connection motor including a pulley so that torque can be transmitted to the shaft via a pulley. However, an indirect connection type engine may have limited applicability.

The driving movement of the drum may be embodied by controlling the engine 140. As a result, the method of controlling the engine may vary, and thereby various driving movements of the drum can be achieved.

Hereinafter, laundry moving patterns and drum driving motions for implementing a laundry moving pattern will be described.

The pattern of shifting the movement of linen can be implemented with a maximum increase in friction between the linen and the drum. For example, when a drum rotates continuously in a predetermined direction at a predetermined speed or less, laundry can be rolled to effect a shifting effect, if the rotation speed of the drum driven in the tumbling motion is defined as a reference speed, the predetermined speed may be a reference speed. For example, a drive movement of a drum configured to rotate a drum at a predetermined speed or less in a predetermined direction can be defined as a 'torsion movement'.

The pattern of disentangling movement may be embodied, for example, by a motion of the base rotation. The movement of the base rotation can be defined as the movement of the continuously rotatable drum with the reference speed in a given direction. In the untangling movement pattern, the laundry is discarded inside the drum at a dumping height of the average level and with an average friction.

The pattern of movement with the blow can be implemented by dropping the laundry inside the drum from the maximum height of the dropping. Such a shock effect can be realized, for example, if the drum rotates at a reference speed or faster to lift the laundry to the highest point inside the drum, and then the drum braking is sharply applied. This drive movement of the drum can be defined as a 'smoothing movement'.

The wiggle pattern can be implemented when the drum rotates in a clockwise / counterclockwise direction at a predetermined speed less than the reference speed. Such a driving motion of the drum may be defined as a 'wiggle motion'.

The rubbing movement pattern can be implemented when the friction between the laundry and the drum increases. For example, if a drum rotating at a reference speed or faster in a clockwise direction brakes sharply and then rotates in a counterclockwise direction, the laundry rolls along the inner circumferential surface of the drum from a predetermined height. Such a driving movement of the drum can be defined as a 'reverse rotation movement'.

Compression saturation and saturation movement pattern can be implemented if washing water is supplied during rotation of the drum at a reference speed or faster. When the drum rotates at a relatively high speed, the laundry can be deployed or extended and held along the inner circumferential surface of the drum, and then the washing water sprayed in the drum passes through the laundry, and then the laundry can be compressed to improve the rinse effect. Such a driving movement of the drum can be defined as a 'saturation movement'.

Various drive movements of the drum configured to implement the aforementioned various laundry movement patterns will be described with reference to the drawings.

Figure 3 is a diagram of various drive movements of the drum, as embodied and described in detail in the materials of this application.

Figure 3 (a) is a torsion motion diagram. During torsion movement, the engine 140 continuously rotates the drum 130 in a predetermined direction, and the laundry placed on the inner circumferential surface of the drum and rotating together with the direction of rotation of the drum is reset from a location that is approximately at an angle less than 90 ° with respect to the direction of rotation of the drum from the lowest point of the drum .

Those. when the motor 140 rotates the drum at a speed that is less than the reference rotational speed (rotational speed when capsizing), for example, at about 40 rpm, the laundry placed at the lowest point of the drum 130 rises to a predetermined height according to the direction of rotation of the drum 130 and then the laundry rolls to the lowest point of the drum from a location that is lower than 90 ° with respect to the direction of rotation of the drum from the lowest point of the drum. Visually, when the drum rotates in a clockwise direction, the laundry constantly rotates in the third quarter of the drum.

When the torsion movement, the laundry is washed with maximum friction with water for washing and with maximum friction with other items for washing, as well as with maximum friction with the inner surrounding surface of the drum. The torsion movement provides the possibility of a sufficient number of turns of linen for the implementation of the effect of washing similar to a gentle kneading of linen. The rotational speed of the drum for driving the movement of the drum can be determined based on the correspondence to the radius of the drum. Those. the higher the rotational speed of the drum, the greater the centrifugal force that is generated for the laundry inside the drum. The difference between the size of the centrifugal force and the gravity applied to the laundry items in the drum varies the drop point of the laundry and the corresponding movement of the laundry inside the drum. The rotational force of the drum and the friction force between the drum and the laundry may also be taken into account. Thus, the rotational speed of the drum during torsion movement can be determined so that the generated centrifugal force and friction force are greater than gravity (1G).

Figure 3 (b) is a basic rotation motion diagram. When the basic rotation movement, the engine 140 continuously rotates the drum 130 in a predetermined direction, and the laundry placed on the inner circumferential surface of the drum, rotating together with the direction of rotation of the drum, is reset from a location located at an angle from approximately 90 ° to 110 ° with respect to the direction of rotation of the drum from the lowest point of the drum. If the rotation of the drum is controlled at a suitable speed in a predetermined direction, during the movement of the basic rotation, the laundry and the drum can mechanically act on each other. For this reason, the movement of the base rotation can be used in washing and rinsing.

Those. before the drive of the engine 140, the laundry loaded into the drum 130 is located at the lowest point of the drum 130. When the engine 140 provides the drum 130 with torque, the drum 130 rotates and the grip 135 provided on the inner circumferential surface of the drum raises the laundry to a predetermined height from bottom point of the drum. If the engine 140 rotates the drum 130 at a reference rotational speed, for example, at about 46 rpm, the laundry can be lifted to a location that is approximately in the range of 90 ° to 110 ° with respect to the direction of rotation of the drum, and then can be reset to the bottom point of the drum. When the base rotation is moving, the drum rotation frequency can be determined so as to allow the generated centrifugal force to be greater than the centrifugal force generated by the torsion movement and to be lower than the gravity.

Visually, if during the movement of the basic rotation the drum rotates in a clockwise direction, the laundry rises sequentially in the third quarter and part of the second quarter from the lowest point of the drum. After that, the laundry is dumped to the lowest point of the drum. As a result, the movement of the basic rotation provides the possibility of washing the laundry during friction with washing water and when hit by dropping. For this reason, during basic rotation movement, a mechanical force greater than the mechanical force arising from the torsion movement can be used to implement washing and rinsing. Also, the movement of the base rotation can be effective in unraveling tangled laundry and evenly distributing the laundry.

Figure 3 (c) is a smoothing motion diagram. In the smoothing movement, the engine 140 rotates the drum 130 in a predetermined direction, and for laundry placed on the inner circumferential surface of the drum, control is performed so as to drop the laundry to the lowest point of the drum from the highest point (approximately 180 °) with respect to the direction of rotation of the drum. When the motor 140 rotates the drum 130 at a speed that is greater than the reference rotational speed (rotational speed when capsizing), for example, at about 60 rpm or faster, the laundry can be rotated by centrifugal force without dropping until the laundry reaches the highest point drum. During the smoothing movement, the drum rotates at a given speed so as not to drop the laundry, and then brakes sharply in order to maximize the impact applied to the laundry when dropping.

After rotating the drum 130 at a predetermined speed that does not allow the laundry to drop (approximately 60 rpm or faster) until the laundry is near the highest point of the drum, the engine 140 applies reverse torque to the drum 130 when the laundry is near the highest point of the drum (180 ° in relation to the direction of rotation of the drum). Thus, the laundry rises from the lowest point of the drum 130 according to the direction of rotation of the drum, and the drum is instantly stopped by the reverse torque of the engine, and the laundry is reset from the highest point to the lowest point of the drum 130. The smoothing movement allows the laundry to be washed away by the shock generated at the moment when the laundry is reset to maximum height. The mechanical force generated by this smoothing motion is greater than the mechanical force generated by the torsion motion or the basic rotation motion mentioned above.

Visually, when the smoothing movement, after moving from the lowest point to the highest point of the drum during rotation of the drum, for the smoothing movement, the drop height inside the drum is the largest, and the mechanical effect of the smoothing movement can be effectively applied to a small amount of laundry. The engine 140 during smoothing movement can be braked by reverse engagement using the torque generated in the opposite direction with respect to the direction of rotation of the engine. The phase of the current supplied to the motor can be reversed to generate reverse torque in the reverse direction of rotation of the motor, and anti-start braking provides the ability to sharply apply braking. Opposition braking can be used to subject the laundry to a strong blow.

Thus, after applying the torque to rotate the drum in a clockwise direction, the torque is applied to rotate the drum in a counterclockwise direction, and the drum is suddenly braked. After that, a torque is applied to the drum for rotation in a clockwise direction and the smoothing movement is embodied. The smoothing movement can be used to wash the laundry using friction between the water passing through the through holes 131 formed in the drum and the laundry using the blow formed by dropping the laundry when the laundry reaches the highest point of the drum. With such a smoothing movement, a washing effect of the “laundry hit” can be generated.

3 (d) is a wiggle motion diagram. With the wiggle movement, the engine 140 rotates the drum in either clockwise or counterclockwise directions, and the laundry is discarded from a location that is approximately below 90 ° with respect to the direction of rotation of the drum. Those. when the engine 140 rotates the drum 130 at a speed that is less than the reference rotation speed (rotation speed when capsizing), for example, at about 40 rpm in the counterclockwise direction, the laundry placed at the lowest point of the drum 130 rises to a predetermined height according to counterclockwise direction. Before the laundry reaches a location located at approximately 90 ° with respect to the counterclockwise direction of the drum, the engine will stop the rotation of the drum, and the laundry will be dropped to the lowest point of the drum from a location located at approximately 90 ° with respect to the counterclockwise direction of the drum.

Further, the motor 140 rotates the drum 130 at a speed that is less than the reference rotation speed (rotation speed when tipping over), for example, at approximately 40 rpm in a clockwise direction to raise the laundry to a predetermined height in a clockwise direction along with the direction drum rotation. Before the laundry reaches a location approximately 90 ° with respect to the clockwise direction of the drum, the engine will stop the rotation of the drum and the laundry will be dropped to the lowest point of the drum from a location lower than 90 ° with respect to the clockwise direction of the drum .

Thus, the wiggle movement is a movement in which rotation and stop in relation to the first direction and rotation and stop in relation to the second (opposite) direction can be repeated. Visually, the laundry that rises to the edge of the second quarter of the third quarter of the drum is reset smoothly, and then re-lifts to the edge of the first quarter of the fourth quarter of the drum and is repeatedly smoothly reset.

In specific embodiments, the engine 140 may use rheostatic braking, and a load can be applied to the engine 140 such that the mechanical wear of the engine 140 can be reduced, and it is also possible to correct the impact applied to the laundry. When rheostatic braking is used, if the current supply to the engine is stopped, the engine acts as a generator due to inertia of rotation, and before turning off the power, the direction of the current flowing in the motor winding is reversed, and for braking along the direction that prevents rotation of the motor, force is applied ( Fleming's right-hand rule). Unlike inhibition braking, rheostatic braking does not provide sudden braking, but instead smoothly changes the direction of rotation of the drum. As a result, while swaying, the laundry can move in the form of a figure 8 through the third and fourth quarters of the drum. A wiggle movement can generate a wash effect of a 'swing of laundry'.

Figure 3 (e) is a reverse rotation motion diagram. When the reverse rotation movement, the engine 140 rotates the drum 130 either in a clockwise direction or in a counterclockwise direction of rotation, and the laundry can be dropped from a location higher than 90 ° with respect to the direction of rotation of the drum.

Those. when the engine 140 rotates the drum 130 at a speed that is higher than the reference rotation speed (rotation speed when tipping over), for example, at about 60 rpm or faster counterclockwise, the laundry located at the lowest point of the drum 130 rises to a predetermined height counterclockwise. After the laundry passes the location at approximately 90 ° with respect to the counterclockwise direction of the drum, the engine provides the drum with reverse torque to temporarily stop the drum, and the laundry placed on the inner circumferential surface of the drum can be quickly reset, which in particular causes the laundry placed on the inner circumferential surface of the drum to be discarded to the lowest point of the drum from a location at 90 ° or higher with respect to the direction of tiv clockwise of the drum. Thus, when reversing the movement, the laundry can be quickly dropped from a predetermined height. Engine 140 for braking the drum may use anti-deceleration braking.

With the movement of the reverse rotation, the direction of rotation of the drum changes rapidly, and the laundry cannot move away from the inner circumferential surface of the drum for a long period of time. For this reason, when the movement is reversed, the washing effect with strong friction can be achieved due to the maximum increased friction between the laundry and the drum. When the reverse rotation movement, the laundry moved to the second quarter region through the third quarter is quickly reset and re-reset after the next movement to the first quarter region through the fourth quarter. As a result, visually when the reverse rotation movement, the lifted linen is cyclically dropped along the inner circumferential surface of the drum.

Figure 3 (f) is a diagram of the movement of saturation. With the saturation movement, the engine 140 rotates the drum 130 in such a way that the laundry is not discharged from the inner circumferential surface of the drum, and the washing water is sprayed in the drum. Those. during saturation movement, the laundry is dispersed and maintained in close contact with the inner circumferential surface of the drum, and washing water is sprayed in the drum. Water flows from the tank through the through holes 131 of the drum under the action of centrifugal force. Since with the saturation movement, the surface area of the laundry increases, and for water it is possible to pass through the laundry, washing water can be supplied to the laundry evenly.

Figure 3 (g) is a diagram of the motion of saturation with compression. When the saturation movement is in compression, the engine 140 rotates the drum 130 so that the laundry is held / not dropped from the inner circumferential surface of the drum using centrifugal force, and then the engine slows down the rotation speed of the drum 130 to temporarily separate the laundry from the inner circumferential surface of the drum. This sequence of operations is repeated, and during rotation of the drum, water is injected into the drum. Those. during saturation movement, the drum rotates continuously at a speed that is sufficient not to drop laundry from the inner circumferential surface of the drum. In contrast, when moving with compression, the rotation speed of the drum changes to repeat the sequence of operations for holding and separating the laundry from the inner circumferential surface of the drum 130.

The injection of washing water into the drum 130 during the saturation movement and during the saturation movement with compression can be carried out, for example, by a pump and a circulation channel. The pump may be connected to the bottom surface of the tank 120, the end of the circulation channel being connected to the pump so that washing water is injected from the tank into the drum through the other end of the circulation channel.

In alternative embodiments, washing water may be injected into the drum through a supply channel connected to an external water supply source located outside the housing. Those. one end of the feed channel is connected to an external supply source, and the other end is connected to the tank. If a spray tip is provided for injecting washing water into the drum, washing water may be injected into the drum in each case of a saturation movement or a saturation movement with compression.

4 is a more detailed diagram of the smoothing movement.

First of all, the laundry moves from the lowest point to the highest point of the drum 130, as shown in FIGS. 4 (a) to (c). As described with respect to the tub 120 fixedly connected to the drum 130, laundry placed in the drum 130 moves from a location near the lowest point of the drum 120 to the highest point of the drum 120. With this movement of the laundry, the motor 140 applies a rotational force, and it is the torque to the drum in a predetermined direction, which is a clockwise direction, as shown in the drawings, and the drum 130 rotates along a predetermined direction with the laundry in order to lift the laundry.

The laundry can rotate with the drum in close contact with the inner surface of the drum 130 due to the frictional force with the grips and the inner surrounding surface of the drum 130. The laundry rises to the highest point of the drum 130 when the drum 130 rotates at approximately 60 rpm or faster without separation away from the drum, since this rotation speed generates a centrifugal force that is sufficient to prevent the laundry from separating from the drum 130 up to the highest point of the drum 130.

The rotation speed of the drum can be changed so that the generated centrifugal force is greater than the force of gravity, which would enable the laundry to rotate with the drum to the highest point of the drum 120 from the lowest point of the drum 130, which is a given point on the inner surface of the drum adjacent to the lowest point of the tank 120. The laundry is dropped from the highest point of the drum 130 to the lowest point of the drum 130 when the drum 130 is suddenly braked, or at the moment when the laundry reaches th high point of the drum 130 or directly before this moment.

More specifically, in order to sharply brake the drum 130, the engine 140 provides the drum 130 with reverse torque. The reverse torque is generated due to braking by an anti-inclusion, which is configured to supply reverse current to the engine 140, as described with reference to FIG. 3 (c). Opposition braking is a type of engine braking that uses the torque generated in the opposite direction with respect to the direction of rotation of the engine. The phase of the current supplied to the motor can be reversed to generate reverse torque in the reverse direction of rotation of the motor, and anti-braking provides the possibility of applying sudden braking. For example, as shown, a current is applied to the motor to rotate the drum in a clockwise direction, and then current is applied to the motor to abruptly rotate the drum in a counterclockwise direction.

The timing for the anti-start braking with respect to the engine 140 may be closely related to the location of the laundry inside the drum 130. For this reason, a device used to determine or predict the location of the laundry may be provided, and an example of such a device may be a measuring device, for example, such as Hall effect sensor, configured to determine the angle of rotation of the rotor. The control component can determine the angle of rotation of the ram through the use of a measuring device and control the engine 140 to brake the counterclockwise moment, or immediately before the drum rotates through an angle of 180 °. As a result, the drum rotated in the counterclockwise direction quickly stops in response to the torque in the counterclockwise direction. The centrifugal force applied to the laundry is eliminated, and at that moment the laundry is reset to the lowest point.

Next, as shown in FIG. 4 (d), the drum continuously rotates in a clockwise direction, and the rotation / dropping of the laundry is repeated. Although FIG. 4 shows that the drum rotates in a clockwise direction, to realize the smoothing movement, the drum can be rotated in a counterclockwise direction. The smoothing movement generates a relatively high load on the engine 140, and the ratio of the resulting action of the smoothing movement can be reduced.

The ratio of the resultant action is the ratio of the drive time of the engine to the total value of the drive time and the stop time of the engine 140. If the ratio of the resultant action is '1', this means that the motor is driven and does not have a stop time. The smoothing movement can be realized at approximately 70% of the resulting action ratio, taking into account the load on the engine. For example, a motor can be stopped for 3 seconds after a drive for 10 seconds. Other drive / stop ratios may also be acceptable.

Before falling laundry reaches the lowest point of the drum, i.e. while dropping the laundry, the drum 130 starts its rotation to implement the next smoothing movement. In this case, the drum 130 is rotated by a predetermined angle, and after that the laundry reaches the lowest point of the drum 130. From this point, the laundry and the drum can rotate together. Although the drum rotates 180 °, as set, laundry cannot be moved 180 °, i.e. to the highest point of the drum 130, and it cannot be dropped from the highest point of the drum to achieve the desired washing ability.

For this reason, the drum 130 is controlled so that it is rotated a second time as shown in FIG. 4 (d) after the laundry has reached the lowest point of the drum. Those. the drum remains stationary until the laundry reaches the lowest point of the drum. More precisely, at the moment when the start of dropping the laundry actually takes place, the drum 130 is stopped. From the moment of dropping, until the moment when the laundry reaches the lowest point of the drum, the drum remains stopped and does not rotate. The stopping time may be longer than the time necessary to drop the laundry to the lowest point (point 1) from the highest point of the drum. As a result, the drum can remain stopped, for example, for 0.4 seconds, or in some embodiments for 0.6 seconds, to provide sufficient time to be in a stopped state. This makes it possible to more accurately realize the smoothing movement to generate maximum impact, and accordingly, the desired washing ability can be provided.

5 is a more detailed diagram of the movement of reverse rotation.

First, the laundry is moved from the lowest point of the drum 130 to a location reached after passing 90 °, or further in the clockwise rotation direction of the drum 130, as shown in FIGS. 5 (a) to (c). As described with respect to the tub 120 remaining stationary and adjacent to the drum 130, laundry inside the drum 130 is moved from a predetermined point on the inner surface of the drum adjacent to the lowest point of the tub 120, with a point on the inner surface of the drum rotated 90 ° or more together in a clockwise direction of the drum 130. To effect such a movement of the laundry, the engine applies a rotational force, i.e. the torque of the drum 130 in a predetermined direction (clockwise direction), and then the drum 130 rotates with the laundry to lift the laundry.

The laundry rotates with the drum in close contact with the inner circumferential surface of the drum 130 due to grip and friction with the inner circumferential surface of the drum, and does not separate from the drum 130. For this, the drum rotates at about 60 rpm or faster to generate sufficient centrifugal force so that the laundry is not separated from the drum 130. The rotation speed of the drum can be set so as to generate a centrifugal force greater than the attractive force, taking into account the size of the drum, n example, the inner diameter. As a result, the laundry rotates with the drum from the lowest point of the drum to a rotation position of 90 ° or further with respect to the lowest point of the drum.

The laundry is then reset from a rotation position of 90 ° or more to the lowest point. For such a discarding of laundry, the drum is braked sharply when the laundry reaches a drum rotation position of 90 ° or more. The engine 140 provides the drum with reverse torque for applying sudden drum braking. As mentioned above, with reference to FIG. 3 (e), the reverse torque is the reverse torque generated by the anti-trip brake, which makes it possible to supply reverse current to the motor 140.

The control component can determine the angle of rotation of the drum using a measuring device, as described above. When the rotation angle of the drum is 90 ° or more, the control component can perform anti-start braking for the engine 140. As a result, the drum 130 rotating in the clockwise direction is provided with a torque in the counterclockwise direction to instantly stop rotation and eliminate the centrifugal force applied to the laundry. As shown in FIG. 5 (c), the laundry cannot be perpendicular to the reset torque in the counterclockwise direction, but is reset to the lowest point of the drum with an inclination with respect to the inner circumferential surface of the drum. Due to tilted dropping, the laundry may have a relatively large amount of friction with the inner surface of the drum during dropping, and the mutual friction between the laundry items and between the laundry and the washing water may be relatively high.

Further, as shown in FIG. 5 (d), the drum continuously rotates in a counterclockwise direction and the rotation / dropping of the laundry mentioned above can be repeated. Figure 5 shows that, first of all, the drum rotates in a clockwise direction, but also counterclockwise movement can be realized first of all. The movement of the reverse rotation generates a relatively large load applied to the engine 140, similar to the smoothing movement, and the ratio of the resulting action for the movement of the reverse rotation can be reduced, for example, by stopping for 3 seconds after which, the movement of the reverse rotation can be repeated, while the ratio the resulting action can be maintained at 70%. Other configurations may also be appropriate.

Before falling laundry gets to the lowest point of the drum, i.e. while dropping laundry, the drum 130 starts its rotation in the opposite direction to implement the next movement of the reverse rotation. In this case, the drum 130 is rotated by a predetermined angle and after that the laundry enters the lowest point of the drum 130. From this point, the laundry and the drum can rotate together. Although the drum rotates as set to 90 °, the laundry cannot be moved 90 °, i.e. to the highest point of the drum 130, and it cannot be dropped from the highest point of the drum to achieve the desired washing ability.

For this reason, the drum 130 is rotated a second time, as shown in FIG. 5 (d), after the laundry reaches the lowest point of the drum. Those. the drum is held back in order to remain stationary until the laundry reaches the lowest point of the drum. More precisely, at the moment when the laundry actually starts to drop, the drum 130 is stopped. From the moment that the laundry is reset until the moment when the laundry reaches the lowest point of the drum, the drum is stationary and does not rotate. The time period of the stationary state of the drum may be longer than the time it takes to drop the laundry to the lowest point of the drum. As a result, the time for maintaining the stationary state of the drum can be set, for example, to 0.2 seconds, which is less than in the case of a stationary state of the drum during smoothing movement.

When setting the time for maintaining the stationary state of the drum, the movement with reverse rotation can be implemented more precisely in such a way as to generate the maximum friction force between the inner surface of the drum and the laundry, the maximum friction force between the laundry items and the maximum friction force between the laundry and water for washing, it is also accordingly possible to achieve the desired washing ability.

6 is a graph comparing the washing ability and the vibration level of each movement shown in FIG. The horizontal axis represents the washing ability, and the easier it is to separate the contaminants present in the laundry, the greater the shift to the left. The vertical axis represents the level of vibration or noise, and the higher the level, the higher it is moved, while decreasing the washing time for the same laundry.

The smoothing movement and the reverse rotation movement are more suitable for washing modes implemented to reduce the washing time when the laundry is heavily soiled. The smoothing movement and the reverse rotation movement have a high level of vibration / noise and are typically not used to wash sensitive fabrics and / or to minimize noise and vibration.

The torsion movement has a satisfactory washing ability and a low vibration level while minimizing damage to the laundry and low engine load. Therefore, the torsion movement can be used in all washing modes, in particular, it helps to dissolve detergents at the initial stage of washing, and also helps to wet the laundry.

The base rotation movement has a lower washing ability than the reverse rotation movement and the average vibration level with respect to the reverse rotation movement and the torsion movement. The torsion movement has a lower vibration level, but it has a longer washing time than the movement of the base rotation. Therefore, the movement of the basic rotation can be used in all washing modes and can be effective in the washing mode with a uniform distribution of linen.

The saturation movement with compression has a similar washing ability as the movement of the base rotation and a higher level of vibration than the movement of the base rotation. The saturation movement with compression repeats the sequence of operations on approaching the laundry and separating the laundry from the inner circumferential surface of the drum. With this sequence of operations, washing water is discharged outside the drum after passing through the laundry. Thus, the saturation movement with compression can be applied to rinse.

The saturation movement has a lower washing ability than the saturation movement with compression and a similar noise level as the torsion movement. During saturation movement, water passes through the laundry and is discharged from the drum, the laundry being in close contact with the inner circumferential surface of the drum. As a result, a saturation movement can be applied to the laundry wetting mode.

The wiggle movement has the lowest vibration and washing ability and can be applied in the low noise and low vibration washing mode and in the washing mode of sensitive or delicate products.

As mentioned above, each drive movement of the drum has its advantages, and it is preferable to use these various drive movements of the drum to maximize the use of these advantages. Each drive movement of the drum may also have advantages and disadvantages with respect to the amount of laundry. Even in the case of the same mode or cycle, different drive movements of the drum can be applied in different ways depending on the amount of laundry.

The inside of the drum for a drum type washing machine should be visible through the door from the outside. In the washing modes, which will be described later, various drive movements of the drum can be implemented. Therefore, the user can see the various driving movements of the drum, which are realized in the inner part of the drum. Those. visually it is possible to determine washing with a weak type of strokes (basic rotation motion), washing with a strong type of strokes (smoothing motion), washing with a weak type of friction (torsion motion) and washing with a strong type of friction (reverse rotation motion). Due to this, the user can realize that the washing is done satisfactorily, which can provide the user with increased satisfaction along with a significantly increased washing ability.

III. WASHING MACHINE MODES

Next, various control methods, i.e. various modes of the washing machine, embodied and described in detail in the materials of this application.

A. Mode A (STANDARD MODE)

Mode A will be described with reference to FIG. Mode A is the standard mode that can be used to wash ordinary laundry without auxiliary options. Mode A includes a wash cycle, a rinse cycle and a spin cycle. A user may select a standard mode using the mode selection component 117 (S710).

A. 1 washing cycle (S730):

The washing cycle includes a water supplying step (S733), in which washing water and detergent are supplied to a tub 120 or a drum 130 for dissolving the detergent in the washing water, and a washing step (S742) configured to drive the washing drum linen. At the stage of water supply, water from an external water supply source together with detergent is supplied to the washing machine. By increasing the efficiency of the water supply stage in preparation for the washing step, it is also possible to successfully achieve a washing cycle efficiency including washing efficiency and reduced washing time.

A.1.1 Determining the amount of laundry (S731):

As mentioned above, the water supplying step is performed in preparation for the main washing step. As a result, the dissolution of the detergent, the wetting of the laundry and the like can be realized quickly and thoroughly. However, taking into account the volume of the drum and the amount of washing water supplied to the drum, in the water supplying step, the driving movement of the drum can be controlled according to the amount of laundry in the drum. Those. based on the amount of laundry in the drum, a drive movement of the drum can be selected to allow more efficient dissolution of the detergent and wetting of the laundry.

The step of determining the amount of laundry, configured to determine the amount of laundry placed in the drum, can be implemented before the step of supplying water. The driving movement of the drum at the stage of water supply may vary depending on a certain amount of laundry.

The amount of laundry can be determined by measuring the electric currents used to drive the drum. For example, the currents used to realize the motion of the base rotation can be measured. To implement the motion of the basic rotation, the control component controls the rotation of the drum at a given speed, for example, at 46 rpm. The current value required to drive the drum at this speed may vary, depending on the amount of laundry in the drum. Thus, the amount of laundry can be determined based on the amount of current required to drive a particular drum at a particular rotation speed in a particular movement.

If the laundry amount is relatively large, sufficient water for washing can be supplied to the drum at the initial stage of the water supplying step, and the washing efficiency can be further improved. In the water supplying step, the driving movement of the drum may vary depending on the amount of laundry, and the parameters of the water supplying step can be determined appropriately.

A 1.2 Water supply (S733):

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

At the initial stage of the water supplying step, a step of determining the type of detergent to determine whether the type of detergent provided during the initial stage of the water supplying step is liquid or powder may be implemented. This step is implemented to determine the driving movement of the drum or the number of rinses in the rinse cycle, which will be implemented after the wash cycle. Information regarding the wash cycle and the rinse cycle may be available to the user through the display component 119 at the time the washing machine is put into operation. For this reason, the step of determining the type of detergent can be implemented at the initial stage of the water supply stage, and more precisely, before the step of facilitating the dissolution of the detergent.

A. 1.2.2 Promoting the dissolution of detergent (S735):

When the washing water and the detergent are supplied in the water supplying step, the step of dissolving the detergent can be implemented. To increase the efficiency of the washing cycle, the detergent can be absolutely and effectively dissolved at the initial stage of the water supply stage. As a result, to facilitate the dissolution of the detergent in the water supplying step, the step of promoting the dissolution of the detergent can be implemented.

The movement, namely the driving movement of the drum to move the laundry in the drum to facilitate the dissolution of the detergent, may be a movement configured to impart a strong mechanical effect on the washing water and on the laundry. For example, in the step of facilitating the dissolution of the detergent, a smoothing movement may be implemented that is capable of cyclically lifting the laundry along with the rotation of the drum and dropping the laundry from the inner circumferential surface of the drum according to the braking applied to the drum. Alternatively, instead of a smoothing movement, a reverse rotation movement may be implemented, configured to lift the laundry together with the rotation of the drum and discard the laundry according to the braking of the drum and rotate the drum in a reverse manner to re-lift the laundry. The smoothing movement and the reverse rotation movement are configured to apply sharp braking to the rotating drum to drastically change the direction of movement of the laundry and apply a strong blow to the laundry. In addition, the smoothing movement and the reverse rotation movement are configured to apply a strong blow to the washing water. As a result, a strong mechanical effect is provided at the stage of the water supply stage in order to accordingly facilitate the dissolution of the detergent and to increase the efficiency of the washing cycle.

In alternative embodiments, the step of facilitating the dissolution of the detergent may be implemented by repeating the sequence of combining the smoothing movement and the reverse rotation movement. In this case, two types of drive movements of the drum are cyclically combined, and patterns of washing water flows can be alternated to increase the efficiency of the washing cycle.

In a typical water supplying step, the drum is driven by a base rotation that continuously rotates the drum in a predetermined direction at a predetermined speed for lifting and dropping laundry. However, it turned out that the time required for the detergent to dissolve in the washing water during the movement of the base rotation can be longer than the time either during the smoothing movement, or during the movement of the reverse rotation, or when combining them. For example, the time for the detergent to dissolve during basic rotation in a typical washing machine may be approximately 15 minutes, while the time required for the detergent to dissolve in washing water during the smoothing movement or during reverse rotation when used in the same washing machine machines can be from 9 to 10 minutes. Thus, the smoothing movement or the reverse rotation movement can dissolve the detergent in the washing water faster, and the corresponding time of the specific washing mode will be reduced.

With the smoothing movement and with the reverse rotation movement, the laundry is discarded, and the blow from the drop is applied to the laundry, while the rotation and stop of the drum can generate a strong whirlpool in the wash water.

In the step of facilitating the dissolution of the detergent, a circulation step may further be implemented, configured to circulate the washing water in the tub and to re-supply the washing water to the drum. In the circulation step, washing water below the drum is supplied inside the drum, further facilitating the dissolution of the detergent and the wetting of the laundry.

In some embodiments, the step of facilitating the dissolution of the detergent may take, for example, about 2 minutes or another amount of time, if necessary, until the water supply is complete. The water supply can be completed at the stage of facilitating the dissolution of the detergent, or water can be additionally supplied, since the water level can be lowered in the next step of wetting the laundry. The step of facilitating the dissolution of the detergent can be implemented in a relatively short period of time so as to slightly damage the fabric of the laundry upon impact. As a result, the driving movement of the drum in the step of facilitating the dissolution of the detergent of each of the aforementioned modes may be a reverse rotation movement, depending on the amount of laundry in the drum.

Those. the step of facilitating the dissolution of the detergent can be implemented if a certain amount of laundry is at a predetermined level or lower, since the driving movements of the drum configured to exert a strong mechanical effect can be more effective with small amounts of laundry, and since small amounts of laundry can provide a satisfactory contact with water for washing. More specifically, a small amount of laundry indicates that the surface area of the laundry to be contacted with the washing water is small, and that the dissolution of the detergent and the wetting of the laundry can be realized by the mechanical force applied to the laundry turning over in a relatively short time. As a result, the smoothing movement or the reverse rotation movement makes it possible to accordingly improve the washing efficiency and reduce the washing time.

In contrast, if the laundry amount determined in the laundry amount determination step is at a predetermined level or higher, the step of facilitating the dissolution of the detergent may be omitted.

Those. if the amount of the laundry is relatively large, the mechanical force is not sufficient to make a satisfactory contact of the laundry with the washing water, since the washing water cannot be sufficiently supplied / absorbed by the tangled laundry.

As a result, if the amount of laundry is at a predetermined level or higher, the step of facilitating the dissolution of the detergent is omitted, and immediately begins the stage of wetting the laundry. If the laundry amount is at a predetermined level or higher, the laundry can make more satisfactory contact with water to facilitate the dissolution of the detergent using the circulation step in the water supply step.

A.1.2.3 Wet laundry (S736):

The step of satisfactorily wetting the laundry with washing water can be implemented at the step of supplying water together with the dissolution of the detergent. In the case of a drum type washing machine, there is no need for the laundry to be completely covered with washing water, and thus, wetting of the laundry can be realized quickly at the initial stage of the washing cycle. After the step of facilitating the dissolution of the detergent, a step of facilitating wetting of the laundry may be implemented to facilitate wetting of the laundry. This stage can be implemented after the implementation of the specified percentage of the water supply stage, or until the water supply stage is completed, in order to guarantee satisfactory saturation of the laundry. Alternatively, the step of facilitating the dissolution of the detergent may be implemented after the end of the water supply. In the laundry wetting step, the water level decreases and an additional water supply can be realized.

The wetting step of the laundry can be partially implemented in the step of facilitating the dissolution of the detergent mentioned above, and the water level can be increased in order to allow enough water to be collected for washing inside the drum. For this reason, the step of facilitating wetting of the laundry can be implemented after the step of facilitating the dissolution of the detergent. The driving movement of the drum of the laundry wetting assistance step may be controlled in a different way as opposed to the detergent dissolution promoting step. For example, the drive movement of the drum of the laundry wetting assistance step may include torsion movement and / or saturation movement. In some embodiments, the saturation movement and the torsion movement can be implemented sequentially.

The saturation movement is a movement in which the laundry is widely dispersed to increase the surface area of the laundry, and thus, the saturation movement can be used to uniformly wet the laundry. A torsion movement is a movement in which the laundry is rotated cyclically in order to make uniform contact with the laundry of water located at the bottom of the drum, therefore, the torsion movement can also be used to wet the laundry. In order to use these effects as much as possible, various drive movements of the drum, i.e. repeated / sequential implementation of the saturation movement and the torsion movement in a predetermined order, which can maximize the efficiency of the laundry wetting assistance step.

If the laundry amount is equal to a predetermined level or is large, the drive movement of the drum of the laundry wetting assistance step may include a saturation movement. Those. during saturation movement, the surface area of the laundry is vast, the laundry is distributed evenly without tangling, thus washing water is evenly supplied to the laundry. Alternatively or in addition to the saturation movement, a basic rotation movement can also be implemented.

If the laundry amount is below a predetermined level, a saturation movement and / or a base rotation movement can be applied during the laundry wetting assistance step.

The user can select the level of soiling of the laundry through the option selection component 118, and depending on this selection, the ratio of the resultant engine action can be set. However, the ratio of the resulting action at the water supply stage may not be established depending on the selected level of contamination due to the fact that the ratio of the resulting action at the water supply stage is set in advance to optimize the dissolution of the detergent and the wetting of the laundry, and because it should not be ignored the likelihood of excessive damage to the laundry. If the ratio of the resulting action decreases, the dissolution of the detergent and the wetting of the laundry cannot be satisfactorily implemented.

The water supplying step in the standard mode may include the step of determining the type of detergent, the step of facilitating the dissolution of the detergent, and the step of assisting the wetting of the laundry described above. In alternative embodiments, the step of determining the type of detergent, the step of facilitating the dissolution of the detergent, and the step of promoting wetting of the laundry may be provided regardless of the step of supplying water. In this case, the step of determining the type of detergent, the step of facilitating the dissolution of the detergent, and the step of assisting the wetting of the laundry can be implemented after the water supply is completed.

A.1.3 Heating (S740):

The washing cycle includes a washing step. To prepare for washing, a heating step may be implemented between the washing step and the water supplying step.

The heating step may be configured to heat the wash water by using a heater provided under the tub or to increase the temperature of the wash water or tub using steam supplied inside the drum. For this reason, the heating step may be used or omitted, if necessary. Those. when using cold air or water for washing clothes, the heating step may not be implemented. However, if the temperature of the washing water is set in advance as greater than the temperature of the cold water based on the default temperature that is associated with the selected course, or if the temperature of the washing water is selected on the component 118 of the option selection as higher than the temperature of the cold water, there may be the heating step is implemented.

The driving movement of the drum during the heating step may vary depending on the amount of laundry. At the stage of heating, the movement of the base rotation can be implemented regardless of the amount of laundry. However, as mentioned above, if the amount of laundry is equal to a predetermined level or is less, a torsional movement can be realized in the heating step. Those. in the case where the amount of the laundry is relatively small, the repeated flipping of the laundry in the lower portion of the drum may be more effective in heating and washing than the distribution of the laundry. Alternatively, with a small amount of laundry at the heating stage, a combination of the movement of the base rotation and the movement of torsion can be used, and with a large amount of linen, the movement of the base rotation can be used.

The heating step may include a heating preparation step to prepare for heating after the water supplying step. This means that the water supplying step is completed after the wetting of the laundry is completed. As a result, after the water supplying step, it is possible to determine the amount of the laundry more accurately, since before wetting the laundry based on the amount of the laundry, it is impossible to recognize the number of wet laundry items in relation to the dry laundry items. For example, before wetting the laundry, the number of wet laundry items may be determined to be greater than the actual amount. As a result, in some embodiments, the step of more accurately determining the amount of laundry may be implemented in the step of heating before washing. If the heating step is omitted, the step corresponding to the preparation step for heating can be implemented to determine the exact amount of laundry. Those. if the heating step is omitted, the step of accurately determining the amount of laundry may be implemented before the washing step, after the completion of the water supplying step.

A.1.4 Wash (S742):

After the completion of the water supplying step and the heating step described above, a washing step configured to wash the laundry may be implemented. The driving movement of the drum at the washing stage may be a sequential combination of the smoothing movement and / or the basic rotation movement and / or the torsion movement to apply strong mechanical stress and move the laundry in a variety of patterns to improve the washing efficiency.

Alternatively, the drive movement of the drum during the washing step may be a sequential combination of the saturation movement and the base rotation movement to continuously supply washing water to the laundry to improve the washing efficiency generated by the detergent, as well as the washing efficiency generated by the mechanical force applied to the laundry.

As a result, the driving movement of the drum in the washing step may vary according to the amount of laundry, since the driving movement of the drum, allowing the generation of the optimal washing effect, may vary depending on the amount of laundry. The laundry amount may be the laundry amount determined before the water supplying step or the heating step. In the washing step, the driving movement of the drum may vary depending on the amount of laundry determined after the water supplying step.

If the laundry amount is equal to a predetermined level or is large, the driving movement of the drum may include a saturation movement and / or a base rotation movement. If the washing machine is not equipped with equipment for circulating washing water, only a basic rotation movement can be realized. In the case of a large amount of laundry, washing water can be supplied to the laundry evenly, and at the same time, mechanical force can be applied to the laundry to improve the washing efficiency.

If the laundry amount is at a predetermined level or lower, the driving movement of the drum may include a smoothing movement and / or torsion movement to increase the washing efficiency, since the laundry will move according to different patterns, applying mechanical force to the laundry. In some embodiments, the base rotation motion may also be implemented with a smoothing motion and / or with a torsion motion.

As mentioned above, in the standard mode, the driving movement of the drum in the water supplying step, the heating step and the washing step may vary, and the efficiency of the washing cycle can be accordingly increased. In addition, the driving movement of the drum at each stage may vary depending on the amount of laundry in the drum, and accordingly, an optimized washing cycle may be implemented.

If the user selects the level of soiling of the laundry on the option component 118, the ratio of the resultant action of the heating step and the washing step may be different. If the resulting action ratio is excessively high in the case in which the level of contamination is relatively low, the laundry may be unreasonably damaged.

A.2 Rinse cycle (S750):

The method of controlling the rinse cycle in mode A will be described with reference to Fig.7. According to this embodiment, the rinse cycle can be implemented as part of a single mode, together with the washing cycle described above, or it can be implemented independently. For simplicity, a rinse cycle control method that is implemented after the washing cycle mentioned in the standard mode will be described below.

A.2.1 First rinse (S751):

Upon completion of the wash cycle, a first rinse step may be performed, configured to supply water and drive a drum to implement the rinse.

In standard mode, one or more spin steps can be implemented in each of the wash cycle, rinse cycle and spin cycle. For example, spin after a wash cycle and spin in a rinse can be implemented. These spin steps may be referred to as 'intermediate spin', which must be distinguished by a spin in the spin cycle, which is the last cycle of the standard mode.

The spin level can be determined based on the rotational speed of the drum. Typically, the intermediate spin may be implemented at about 200 to 400 rpm and, for example, at about 400 rpm in delicate mode, about 600 rpm in cautious mode, about 800 rpm in medium mode, and about 1000 rpm in intensive mode. The rotational speed of the drum for the intermediate spin can be selected based on the lower resonant frequency and the upper resonant frequency during operation, depending on the current operating parameters.

The resonant frequency is a characteristic physical value of the washing machine, while the vibration of the washing machine increases substantially near the resonant frequency. If the drum rotates near the resonant frequency and the laundry is not evenly distributed, the vibration of the washing machine will increase very sharply. Therefore, if the spin cycle is realized at a predetermined rotational speed higher than the resonant frequency, the laundry unraveling step is typically implemented to distribute the laundry uniformly inside the drum, and vibration is measured. If the measured vibration is less than a predetermined value, an acceleration step may be implemented to exit the resonant frequency band.

Since the water supply and rinsing are repeated many times in the rinse cycle, the time required by the intermediate spin that occurs at the time of rinsing will be large. To eliminate the likelihood of detergent precipitation after washing, the rinsing steps in the wash cycle can be implemented at least three times or more. An intermediate spin realized at this time can add a considerable amount of time to the rinse cycle, resulting in an excessively long rinse cycle. According to this embodiment, the rotation speed during the intermediate spin realized during the water supply and rinsing may vary. Those. the drum can rotate at a given speed, lower than the lower resonance frequency in a given specific intermediate spin and at a given speed, higher than the upper resonant frequency with another specified specific intermediate spin.

When a particular intermediate spin is realized at a rotational speed lower than the lower resonance frequency, the time required by the auxiliary untangling step, the vibration measuring step and the acceleration step may be unnecessary, thus, the time required by the rinsing cycle is potentially reduced. The speed for this intermediate spin can be set approximately in the range from 100 to 110 rpm. In contrast, if a particular intermediate spin is realized at a rotational speed lower than the lower resonant frequency, the time required for the rinse cycle can be reduced, but the washing water including the detergent may not be completely drained.

After a wash cycle in washing water, most contaminants and detergent residues can be detected. For this reason, after the washing step, the washing water can be drained from the laundry as much as possible.

In standard mode, at the initial stage of the first rinse stage after the washing cycle, high-speed spinning can be realized (S752). During high-speed spinning, the drum can rotate at a speed higher than the upper resonant frequency so that the maximum amount of water can be drained from the laundry. For example, the speed may be set to approximately 1000 rpm. The high-speed spin step can continuously rotate the drum at high speed, i.e. at approximately 1000 rpm, regardless of the user's choice, so that the remnants of the detergent before rinsing can be drained as much as possible.

When the high-speed spin is completed, the first drum drive step (S753) for driving the drum after supplying the rinse water may be implemented. The rinse water level may be a relatively high level, allowing the water level to be visible through the door, in addition, the laundry is immersed in the wash water. Thus, a significant amount of washing water can be supplied at the initial stage of the rinse for rinsing the laundry.

The driving movement of the drum in the first drum driving step may be a reverse rotation movement and / or a wiggle movement to move the maximum amount of laundry covered with washing water to increase rinse performance. These reverse rotation and / or wiggle movements correspond to the sequence of operations of continuous manual friction of the laundry under the wash water after the laundry is placed in the wash water. The basic rotation movement and the smoothing movement correspond to the sequence of operations for the cyclical movement of the laundry in and out of the wash water. As a result, in the first drum driving step, it is possible to control the drum driving in reverse rotation and / or swaying motion at a high water level, allowing the user to visually identify that a satisfactory rinse is being realized. In alternative embodiments, a circulation step may be implemented in the first drum drive step to circulate the wash water in the tub to the drum. Laundry water is injected into the rinse drum. This operation may be called a 'spray rinse'. It also displays to the user that a satisfactory rinse is being implemented, as the operation can be seen through the door.

When the first drum drive step is completed, the first drain step and the intermediate spin step may be implemented (S754). During the discharge of water, the drum may be driven by smoothing and / or basic rotation. To increase the efficiency of washing, the laundry rises and folds, and to increase the effectiveness of rinsing, bubbles are generated. The driving movement of the drum may vary depending on the amount of laundry. In the case of a small amount of laundry, the drum is driven in a smoothing movement to generate a maximum drop height. In the case of a large amount of laundry, the drum may be driven by basic rotation.

At the first discharge, the intermediate spin may be implemented in the range of approximately 100 to 110 rpm. In this case, the step of unraveling the laundry, the step of measuring vibration and the step of acceleration can be omitted and the required time can be significantly reduced.

In alternative embodiments, in standard mode, during the first drain and intermediate spin phase, the intermediate spin may be implemented at approximately 400 rpm higher than the lower resonant frequency. In this case, a smoothing movement and / or a basic rotation movement can be realized, wherein the water drains and the laundry is appropriately dispersed. For this reason, the unraveling step of the laundry may be omitted. Even at a rotation speed greater than the lower resonant frequency, an intermediate spin cycle with a vibration measurement step and a single acceleration step can be realized over a short period of time. Such an intermediate spin may be implemented at a relatively high speed to drain detergent residues and contaminants that have not been drained by the high speed spin step. However, in the case where the vibration amount measured in the vibration measuring step is outside acceptable limits, the vibration measuring step may be repeated in such a way that it is not possible to start the acceleration step, and the rinsing time may be adversely increased. For this reason, the vibration measurement step can be implemented at a drum speed in the range of approximately 100 to 110 rpm, and in the case where the acceleration step does not begin within a predetermined number of implementations of the vibration measurement step, the first discharge and intermediate spin may be completed.

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

The second rinse step (S756) may follow the first rinse step. The second rinse step may include a second drum drive step (S757), as well as a second drain and intermediate spin step (S758). The second drum drive step may be substantially the same as the first drum drive step described above. Also, the second drain and intermediate spin step may be substantially the same as the first drain and intermediate spin step. However, an intermediate drain to reduce rinsing time is approximately in the range from 100 to 110 rpm at the second drain and intermediate spin phase, since the remaining detergents have already been drained at the high-speed spin stage and the first drain and intermediate spin phase.

The rinse cycle can take advantage of the determination of the detergent type.

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

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

The water level of the final rinse step (S760) may be relatively low. In the case of a washing machine with an inclined drum, in which the drum is inclined by a predetermined angle, the water level may be a predetermined level sufficient to supply water only to a predetermined rear portion of the inclined drum. Those. the water level may be such that it cannot be detected or seen from the outside of the washing machine. However, this water level is set so as to no longer generate bubbles in the laundry. Even if bubbles are generated, bubbles are generated in the tank and not in the drum to prevent excess accumulation. As a result, the user can visually identify that no bubbles are generated at the final rinse step, and this will increase satisfaction with the rinse performance.

To implement the spin cycle in the final rinse step after the third drum drive step (S761), the third drain step can be implemented (S762). In the third discharge step, for even distribution of the laundry, the drum may be driven into a smoothing movement and / or a reverse rotation movement.

A.3 Spin cycle (S770):

A method for controlling the spin cycle in the standard mode will be described with reference to Fig.7. The spin cycle can be implemented as part of the standard mode in conjunction with the wash cycle and spin cycle, or independently as a single mode. For simplicity, a method for controlling the spin cycle that is realized after the washing cycle and the rinse cycle, forming a standard mode, will be described.

A.3.1 Unraveling laundry (S771):

The spin cycle may include a laundry unraveling step configured to unravel the laundry by driving the drum to uniformly unravel the laundry. The spin cycle is designed to minimize the vibration generated when the drum rotates at high speed. If the drum at the drainage stage immediately before the spin cycle is driven into smoothing motion and / or reverse rotation motion, the laundry due to the smoothing motion and / or reverse rotation motion will be untangled to a predetermined degree, and the time required for the laundry untangling step can be significantly reduced .

A.3.2 Measurement of eccentricity (S773):

After the laundry unraveling step, the amount of eccentricity during the rotation of the drum at a predetermined rotational speed less than the lower resonance frequency for a predetermined period of time can be measured by accelerating the drum and determining whether the laundry is distributed evenly inside the drum.

The step of measuring the eccentricity of the spin cycle in the standard mode according to another embodiment may be implemented before the step of unraveling the laundry. Due to the drive movement of the drum of the rinse cycle, unraveling of a significant amount of laundry can be realized. As a result, to reduce the spin cycle time, the spin cycle can begin with the step of measuring the eccentricity. If the measured eccentricity in comparison with the value of the reference eccentricity is determined to be satisfactory, acceleration can be realized, which will be described later. If the measured eccentricity is determined to be unsatisfactory in comparison with the value of the reference eccentricity, a laundry unraveling step may be implemented. To facilitate the unraveling of the laundry, the drum can be driven into a smoothing motion during the unraveling process, and the eccentricity measurement step can be restarted after the uncoiling process.

A.3.3 Acceleration and normal spin (S775):

After the step of measuring the eccentricity, the step of accelerating the drum to the normal speed for spinning (the step of acceleration) can be implemented. After that, to complete the spin cycle, a conventional spin step may be implemented, configured to rotate the drum at a normal spin speed. The normal spin speed of the drum may default to approximately 1000 rpm. Those. To minimize detergent residues, the amount of moisture contained in the laundry can be reduced as much as possible. The speed during normal spinning can be changed according to the user's choice, since the speed during normal spinning is related to the level of residual moisture and the number of folds of laundry after spinning is completed. As a result, the user can select the frequency of rotation of the normal spin phase, associated with the level of residual moisture and the number of folds of linen.

B. MODE B (HEAVY DUTY MODE):

The severe soiling mode B, in which heavy soiling must be removed from the laundry, will be described with reference to FIG. The severe pollution mode can be selected using the mode selection component 117 (S810).

B.1 Washing cycle (S830):

B.1.1 Determining the amount of laundry (S811):

After selecting a heavily soiled mode, a step of determining the amount of laundry to determine the amount of laundry loaded in the drum may be implemented. The method for determining the amount of laundry may be similar to the method described above with respect to the standard mode, and thus, its re-description will be accordingly omitted. The step of determining the amount of linen may be implemented before the step of selecting a mode.

The control component compares the laundry amount determined in the laundry amount determination step with the reference value, and controls the driving movements of the drum of the water supplying step and the washing step, which will be described later, based on the comparison result. Essentially, a certain amount of laundry that is larger than the reference value can be taken into account as a large load, and a certain amount of linen that is smaller than the reference value can be taken into account as a small load. The driving movements of the drum of each stage according to a certain amount of laundry will be described.

B.1.2 Water supply (S833):

In the water supplying step, the control component controls the water supplying device (for example, the water supplying channel and the water supplying valve) connected to the water supplying source and the tub to supply washing water to the tub. If the laundry amount measured in the laundry amount determination step is less than the reference value, the control component can control the drum to drive the base rotation and / or the smoothing movement and / or the reverse rotation movement and / or the saturation movement and / or torsion movement.

First, if the laundry loaded in the drum is entangled, an eccentric rotation of the drum will be generated, therefore, in the water supplying step for unraveling the laundry, the control component can drive the drum in basic rotation. In the case of a basic rotation movement, the drum rotates in a predetermined direction, and the laundry is dropped to the lowest point of the drum from a location located at about 90 ° or further with respect to the direction of rotation of the drum, so that entangled laundry can be unraveled and evenly distributed.

The control component controls the drum to rotate in a smoothing movement and / or reverse rotation movement such that a blow due to dropping is applied to the laundry loaded in the drum. The smoothing movement and the reverse rotation movement can be applied to gradually eliminate persistent contaminants. As a result, since the drum is driven by a smoothing motion and / or a reverse rotation motion, persistent contaminants can be removed at the water supply stage, whereby reduced washing time and improved washing efficiency can be achieved.

The water supplying step supplies washing water to the tub and wets the laundry loaded in the drum as described above. For this reason, to perform laundry wetting, the control component may cause the drum to move in a saturation movement after the smoothing movement and / or reverse rotation movement.

In addition, in the water supplying step, the control component can cause the drum to rotate in order to dissolve the detergent in the wash water, in addition to the torsion movement to wet the laundry in the wash water.

If the laundry amount is larger than the reference value, the control component in the water supplying step may control the drum to drive the base rotation and / or the saturation movement. If the laundry amount is relatively large, more precisely, larger than the reference value, a drum movement configured to apply sudden drum braking, for example, a smoothing movement and / or a reverse rotation movement, can apply a very high engine load. Accordingly, it is not possible to provide an exemplary effect for smoothing movement and / or reverse rotation movement that apply shock by dropping. Thus, if a large amount of laundry is loaded into the drum, the smoothing movement and / or the reverse rotation movement are not applied. Also, if a large amount of laundry is loaded into the drum, it is not possible to achieve a wetting effect of the laundry generated by a torsion movement having a relatively low rotational speed, and instead, a basic rotation movement can be implemented to wet the laundry. Essentially, if the laundry amount is larger than the reference value, the drum may be driven in a basic rotation and / or saturation movement such that effects of distribution of the laundry, removal of persistent contaminants, wetting of the laundry, and dissolution of the detergent mentioned above can be achieved.

B.1.3 Wash (S835):

After the completion of the water supplying step, the washing step of the heavily soiled condition may begin. The step of washing the heavily soiled regime may include an impregnation step, a step for removing contaminants, and a step for removing remaining contaminants. In this case, washing water having different temperatures can be suitably supplied for the respective implementation of each step.

B.1.3.1 Impregnation (S836):

The stage of impregnation is a sequence of operations for impregnating linen in cold water for peeling strong contaminants on the linen. Relatively cold water, having a temperature of, for example, approximately 15 ° C, is used in the impregnation step to exfoliate the protein components contained in heavy contaminants on the laundry for a long period of time. If these protein components come into contact with heated water, these strong contaminants tend to solidify on the laundry, and it becomes difficult to separate them from the laundry. For this reason, the impregnation step can be implemented using cold water to prevent strong contaminants having protein components from attaching to the laundry.

If the laundry amount is less than a predetermined value, the motor may drive the drum in a smoothing motion. After the smoothing movement is completed, a base rotation movement and / or a torsion movement can be added. Since the smoothing movement has excellent washing ability and reduced washing time, heavy soiling located on the laundry can be impregnated, and a blow can be applied to the laundry. As a result, the smoothing movement produces an effect including the separation of heavy contaminants from the laundry.

If the laundry amount is larger than the reference value, the drum in the impregnation step may be driven by a base rotation and / or torsion movement. Those. if the measured amount of laundry is greater than the predetermined reference value, the smoothing movement may not be applied due to the excessive load that may be applied to the engine. As noted above, the smoothing movement to increase the washing efficiency applies a blow by dropping the laundry inside the drum. However, if the amount of laundry is large, the smoothing movement may not be realized. When the amount of laundry is greater than the reference value, the smoothing movement is also not realized at the stage of removing contaminants and the stage of removing remaining contaminants, which will be described later.

B.1.3.2 Removal of contaminants (S837):

After the impregnation step, a decontamination step may begin, configured to heat the wash water to a temperature of from 35 ° C to 40 ° C. The temperature of the washing water used in the step of removing contaminants is set in the range of 35 ° C to 40 ° C, because at a temperature that is similar to the temperature of the human body, it is easier to remove components of sebum contained in heavy contaminants. A heater provided on the bottom surface of the tank, or a moisture supply device configured to supply heated moisture, for example steam to the tank, can be used to increase the temperature of the washing water up to a predetermined range.

At the stage of removing contaminants, the control component can control the engine to drive the drum into basic rotation and / or torsion movement if the laundry amount is equal to or less than the reference value. A basic rotation movement and / or a torsion movement with high washing efficiency can impose a small load on the engine and reduce the washing time. For this reason, a reduced washing time can be achieved.

If the laundry amount is larger than the reference value, the control component can control the drum to drive the base rotation. In the case of a large amount of laundry, a torsion movement configured to rotate the drum at a relatively low speed may not be effective in removing contaminants, and thus a basic rotation movement can be applied.

B.1.3.3 Removal of remaining contaminants (S838):

The control component after the step of removing contaminants may implement the step of removing remaining contaminants, configured to heat the washing water to a temperature of about 60 ° C for sterilization and bleaching of the laundry. For sterilizing and bleaching laundry, the temperature of the washing water in the step of removing remaining contaminants may be approximately 60 ° C or higher.

At the stage of removing the remaining contaminants, the control component can control the drum to drive the smoothing motion or in the sequence of smoothing motion and / or basic rotation and / or torsion motion, if the amount of laundry is less than the reference value.

If the laundry amount is larger than the reference value, in the step of removing remaining contaminants, the control component can control the drum to drive a saturation movement and / or a base rotation movement.

B.2. Rinse Cycle (S850):

The rinse cycle of the heavily soiled mode can be similar to the rinse cycle of the standard mode described above and the rinse cycles of the other modes, which will be described later. Thus, a repeated description of the rinse cycle will be omitted.

IN 3. Spin cycle (S870):

The spin cycle of the heavy contamination mode can be similar to the spin cycle of the standard mode described above and the spin cycles of other modes, which will be described below. Thus, a repeated description of the spin cycle will be omitted.

C. Mode C (RAPID BOILING MODE)

Mode C will be described with reference to Fig.9. Mode C may be referred to as a 'quick boil mode' and may be configured to heat the washing water to a predetermined temperature in a relatively short period of time in order to achieve the effect of sanitary boiling of the laundry, for example, in a sanitizing cycle.

Typically, when sterilizing and bleaching the laundry, the washing water in the tub is heated to a “predetermined temperature”, and then the washing is realized. Since the washing time is relatively long, and the power supply is consumed in large quantities only for heating water, heating the washing water in the tank to a predetermined temperature consumes a large amount of electricity and takes a fairly large amount of time. In the fast boiling mode, the laundry can be sterilized and bleached also with a decrease in the total washing time and a decrease in food intake. The rapid boiling mode heats the washing water supplied to the tank for a predetermined period of time, regardless of the temperature of the washing water, instead of heating the washing water until the water reaches a predetermined temperature. In order to take into account the washing ability, the step of compensating the washing step provided according to the temperature of the washing water, as will be described with reference to FIG. 9, may be included in this fast boiling washing mode.

First, the user can select the fast boiling mode using the mode selection component 114 (S910). Then, the control component implements the time setting step for the washing step of the rapid boiling mode. This time setting step allows the control component to determine the time required by the washing step of the rapid boiling mode, which is stored on a memory device, for example, in memory. This step may be implemented similar to the step of selecting a mode or the step of supplying water.

C.1 Washing cycle (S930):

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

As soon as the user selects the fast boiling mode, the control component can implement the step of determining the amount of linen, configured to measure the amount of linen, and the step of setting the washing time, configured to based on the amount of linen to set the time required by the step of washing the mode of rapid boiling. The control component for determining the amount of laundry may use the time used to rotate the drum to a predetermined location, as described above, or the time of residual rotation, after turning the drum in a predetermined period of time.

At the step of setting the washing time, the control component can select the washing time corresponding to the measured amount of laundry from the characteristic periods of the washing time stored in the memory. The variety of values of the time periods required by the washing step of the quick boiling mode is stored in a memory device, for example, in memory so that when the fast boiling mode is selected, the control time can be selected by the control component inherent in it.

C.1.2 Water supply (S933):

The fast boiling cycle may include a water supply step configured to supply water to the tank. In the water supplying step, the control component controls the water supplying device (for example, the water supplying channels and the water supplying valve) connected to the water supplying source and the tank to supply water to the tank. Also, the control component controls the drum to drive into a similar driving movement of the drum as the driving movement of the drum of the water supplying step, for example, the severe pollution mode described above, and thus, a further detailed description will be omitted.

C.1.3 Step for measuring water temperature / Compensation (S935):

After the water enters the tank, the control component measures the temperature of the washing water using the temperature sensor provided in the washing machine and compares the measured temperature with the reference temperature to correct the time of the washing step.

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

As mentioned above, in this mode, the washing step can be implemented after a predetermined period of time for heating the water, regardless of the temperature of the water. For this reason, after the completion of the heating step, the temperature of the washing water in the tank may have different values depending on the temperature of the water supplied to the tank, and there will be a difference in washing ability due to different water temperatures. As a result, after the heating step, in order to minimize the difference in washing ability caused by different temperatures of the washing water, a compensation step is provided. If the temperature of the washing water is lower than the reference temperature, the time of the washing step is increased to compensate for the washing ability at a lower temperature.

The number of reference temperature values used to determine the temperature range can be adjusted accordingly. For example, in one embodiment, one reference temperature may be provided, and in alternative embodiments, multiple reference temperatures may be provided. When the temperature of the washing water is higher than the first reference temperature (e.g., 50 ° C), and there are three reference temperatures, i.e. the first, second and third reference temperatures are provided, the control component can immediately implement the washing step. When the measured temperature of the washing water is lower than the first reference temperature and higher than the second reference temperature, the second reference temperature (e.g., 40 ° C) being lower than the first reference temperature (e.g., 50 ° C) and when the measured temperature is lower than the second reference temperature and higher than the third reference temperature, wherein the third reference temperature (e.g., 30 ° C) is lower than the second reference temperature (e.g., 40 ° C), and when measured pace the temperature is lower than the third reference temperature, a compensation step is implemented, configured to compensate for the time of the washing step predetermined at the step of setting the washing time.

When the time of the washing step is compensated, the control component may select a different compensation time depending on the temperature of the washing water. The washing ability is essentially a proportion of the temperature of the washing water. For this reason, the lower the measured temperature of the washing water, the longer the compensated time. The reference temperature and the range of times added in the compensation step can be predefined based on the volume of the washing machine and other factors.

C.1.4 Heating (S937):

As soon as at the compensation stage, the predetermined time of the washing stage is compensated, for a given period of time, a heating step can be implemented, which is able to remove contaminants on the laundry by moving the drum and at the same time heating the washing water. The heating step may be implemented as an independent step or as part of a washing step, which will be described later. For simplicity, the heating step will be described as part of the washing step in this mode description.

C.1.5 Wash (S939):

The drive drum movement of the washing phase of the rapid boiling mode may include a smoothing motion and / or a base rotation motion and / or a torsion motion.

The smoothing movement has an excellent washing ability and applies a blow to the laundry in such a way that dirt fixed on the laundry can be removed and the washing time can be shortened. As a result, at the initial stage of the washing step, the control component can rotate the drum in the smoothing movement. In this case, the heating step may be implemented after the smoothing movement of the washing step.

When the smoothing movement, the drum rotates at a given speed, allowing the laundry due to centrifugal force not to be dumped from the inner circumferential surface of the drum. When the laundry is near the highest point of the drum, reverse torque is applied to the drum. The load applied to the engine in the case of smoothing movement is greater than in the case of any other driving movement of the drum. For this reason, if the heating step, configured to heat the washing water, continues during the smoothing movement, the power consumption will increase, and a safety problem may arise due to the increase in the current consumption. As a result, the heating step can be implemented for a predetermined time after the smoothing movement is completed.

The heating step is performed in such a way that the heater is not driven for a predetermined period of time, and it is also not necessary to bring the heater until the temperature of the washing water reaches a predetermined value. This allows you to accurately predict the time period and the amount of electricity required for the washing phase, and the user can be notified of the forecast data. Therefore, the washing step can be implemented essentially only during the same predetermined time, regardless of the temperature of the washing water supplied in the water supplying step, so that power consumption and washing time can be reduced.

Therefore, the control component may implement a base rotation motion and / or torsion motion. In this case, the motion of the base rotation and / or the torsion motion can be realized simultaneously with the start of the heating step. The base rotation and torsion motion apply a low engine load and have satisfactory washing ability with reduced washing time. As a result, when the base rotation moves and the torsion movement, it is possible to achieve the effect of decreasing the washing time required by the washing step and the effect of satisfactory washing ability, even at the washing step, which is implemented using washing water having a different temperature.

C.2 Rinse cycle (S950):

The rinse cycle of the quick boiling mode may be similar to the rinsing cycles of the modes described above and the rinsing cycles of other modes, which will be described below. Thus, its further detailed description will be omitted.

C.3 Spin cycle (S970):

The spin cycle of the fast boiling mode may be similar to the spin cycles of the modes described above and the spin cycles of other modes, which will be described below. Thus, its further detailed description will be omitted.

D. MODE D (COLD WASH MODE):

The cold wash mode D will be described with reference to FIG. 10. The cold wash mode D is configured to wash clothes without heating the wash water, thereby saving energy while not reducing the desired washing ability. As a result, in this mode, the temperature of the washing water supplied to the tank is measured, the measured temperature is compared at a predetermined temperature, and the operational parameters are adjusted to ensure that the washing ability is maintained. For example, if in the cold wash mode based on comparison, the temperature of the washing water does not reach the reference temperature, the washing time is compensated in such a way as to provide a sufficient target washing ability.

First, the user can select the cold wash mode using the mode selection component 117 (S1010). Once the user has selected the cold wash mode, the control component can implement the wash cycle, rinse cycle and / or spin cycle one by one or selectively.

D.1 Wash Cycle (First Embodiment) (S1030):

D.1 Determining the amount of linen / Setting the washing time (S1031):

As soon as the user selects the cold wash mode, the control component may implement the laundry amount determination step configured to measure the laundry amount and the washing time setting step configured to set the time required by the cold wash course washing step based on the measured laundry amount. In the step of determining the amount of laundry, the control component for measuring the amount of laundry may use the time required to rotate the drum to a predetermined location or the time of residual rotation of the drum, as described above. At the step of setting the washing time, the control component can select a washing time corresponding to the measured amount of laundry from the characteristic values of the washing time periods stored in the memory in accordance with the amount of the laundry.

D.1.2 Water supply (S1033):

The wash cycle of the cold wash may include a water supply step configured to supply washing water to the tub. In the water supplying step, the control component controls the water supplying device (for example, the water supplying channel and the water supplying valve) connected to the water supplying source and the tank to supply water to the tank. Also, the control component controls the drum to drive into a similar drive movement of the drum as the drive movement of the drum of the water supplying step, for example, a heavily soiled mode, or a fast boiling mode, which are described above. Thus, its further detailed description will be omitted.

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

After the washing water is supplied to the tank, the control component can measure the temperature of the washing water using the temperature measuring device provided in the washing machine. The control component can compare the measured temperature with the reference temperature (e.g. 15 ° C). If the measured temperature of the washing water is equal to or higher than the reference temperature, the control component according to the amount of the laundry may implement the washing step without compensating for the washing time. If the measured temperature is lower than the reference temperature, the control component may implement the step of compensating for the washing time. In this example, a temperature of 15 ° C is presented as an example of a critical temperature guaranteeing a cold washing ability and as a reference reference to a washing ability using cold water. As a result, if the measured temperature of the washing water is lower than the reference temperature, the control component can correct the time of the washing step set in the step of setting the washing time. For example, if the measured temperature is lower than the reference temperature, the control component may add a predetermined time to the time of the washing step to prevent deterioration of the washing ability due to the use of cold washing water having a lower temperature than the reference value. For example, if the measured temperature of the washing water is less than about 10 ° C, 10 minutes may be added to the time of the washing step in the step of compensating the washing time. If, for example, the measured temperature is greater than 10 ° C and less than 15 ° C, 5 minutes can be added to the time of the washing step.

D.1.4 Wash (S1037):

After compensating for the time of the washing step, the amount of laundry measured in the step of determining the amount of laundry mentioned above is compared with a reference value of the amount of laundry, and then a washing step including various driving movements of the drum realized according to the amount of laundry can be implemented. The reference value of the laundry amount may be predetermined based on the laundry amount that allows the smoothing movement to be performed, taking into account the drum size and engine power. For example, the reference value of the amount of laundry may be an average value of the washing volume of the washing machine (approximately 5 to 6 kg in a washing machine having a volume of 11 kg). First, a case will be described in which the measured value of the laundry amount is smaller than the reference value of the laundry amount, and then a case in which the measured value is equal to or greater than the reference value will be described.

When the measured value of the laundry amount is less than the reference value of the laundry amount, the control component for implementing the washing step controls the smoothing movement and / or the base rotation movement and / or the torsion movement. The smoothing movement applies a blow by dropping for the laundry loaded into the drum, and the dirt on the laundry can be easily removed even if cold water is used. If the laundry becomes tangled during the washing step, an eccentric rotation of the drum may occur. Therefore, the control component drives the drum in a base rotation and / or torsion movement to unravel and distribute entangled laundry.

When the measured value of the laundry amount is equal to the reference value or is large, the control component controls the saturation movement and / or the basic rotation movement, which should be implemented in the washing step. If the laundry amount is equal to the reference value or is large, a large load contributes to the difficulty in achieving the effect of applying a blow to the laundry during smoothing movement, as well as the complexity of the torsion effect of the laundry along the circumferential surface of the drum during torsion movement. For this reason, to ensure the effect of the washing ability and the distribution effect of the laundry, a saturation movement and a basic rotation movement can be implemented separately or sequentially.

D. 1 'Washing Cycle (Second Embodiment) (S1130):

11 is a diagram of a cold wash mode according to the second embodiment, as described in detail in the materials of this application.

Compared to the cold wash mode according to the first embodiment, in the cold wash mode according to the second embodiment, the washing time setting step and the compensation step are omitted, and instead, if the temperature of the washing water is less than 15 ° C, the washing water is heated using heater. Those. in the washing cycle according to the second embodiment of the invention, the laundry amount is determined (S1131), and the water supplying step (S1133) can be implemented immediately without setting the washing time. After that, the temperature of the washing water is measured (S1135) for implementing the washing step (S1137). In the washing step according to the second embodiment, which is similar to the first embodiment described above, the driving movement of the drum may vary depending on the amount of laundry. The washing step according to the second embodiment may, based on the measured temperature of the washing water, further include a heating step.

A case will be described in which the amount of laundry measured in the washing step is less than the reference value, in which the driving motion of the drum includes a smoothing motion and / or a base rotation motion and / or torsion motion.

If the measured temperature of the washing water is less than the reference value, a smoothing movement is implemented after the start of the washing step. After the smoothing movement, a heating step may be implemented, configured to heat the washing water using a heater or a moisture supply device provided in the tank. The heating step begins after the smoothing movement, since the smoothing movement applies an increased load on the engine, as mentioned above. If the heating step and the smoothing movement are realized at the same time, for this reason a safety problem may arise, as well as a deterioration in the washing ability. Moreover, if, in order to avoid the above-mentioned problems, the heating step is realized before the smoothing movement, the washing time will be unprofitable to increase. Thus, in this embodiment, the heating step begins after the smoothing movement is completed.

At the start of the heating step, the control component can sequentially implement the base rotation motion and the torsion motion. There is no likelihood of deterioration of the washing ability and safety for the base rotation and torsion movement, and the washing time may be reduced even if they are realized simultaneously with the heating step.

After the heating step, the temperature of the washing water is re-measured, and it is determined whether the re-measured temperature has reached the reference temperature. If the temperature of the washing water reaches the reference temperature, the heating step may be completed. However, if the temperature of the washing water has not reached the reference temperature, the heating step may be continued during the washing step. Moreover, even if the temperature of the washing water that is heated in the heating step cannot reach the reference temperature, the heating step also ends when the washing step is completed.

If the measured temperature is equal to the reference temperature or is higher, the control component drives the smoothing motion and / or the base rotation motion and / or torsion motion essentially similar to those in the description of the driving motion of the drum according to the first embodiment, and a further description thereof falls.

If the laundry amount is equal to the reference value or is large at the washing step, the control component may cause the drum to move in a saturation movement and / or in a base rotation movement. At the same time, if the measured temperature of the washing water is lower than the reference temperature, a heating step may be provided. As described above, during the heating step, the drum is not driven into the smoothing movement.

D. 1 '' washing cycle (third stage of implementation) (S1230):

Fig is a diagram of a cold wash according to the third variant of implementation, as described in detail in the materials of this application.

Compared to the cold wash mode according to the first embodiment described above, in the cold wash mode according to the third embodiment, warm water is supplied to the tank if the temperature of the washing water supplied in the water supplying step is below about 15 ° C. Those. after determining the amount of laundry (S1231), the control component may implement the step of supplying water (S1233), configured to supply washing water to the drum based on the determined amount of laundry, neglecting the step of setting the washing time and the compensation step.

During the implementation of the water supplying step, the control component supplies cold water to the tank (S1234), and can also implement the step of measuring the water temperature (S1235) and the cold water supply at the same time. In this case, if the measured temperature of the washing water is 15 ° C or higher, the washing step (S1240) can be implemented according to the amount of laundry loaded in the drum. If the measured temperature is less than 15 ° C, a warm water supplying step may be implemented (S1236).

The water supplying step may continue until the amount of cold water and the amount of warm water supplied in the water supplying step reaches the amount of washing water determined according to the amount of laundry. After completing the water supplying step, the implementation of the washing step according to the amount of the laundry can be started. In the washing step, the driving movement of the drum may vary depending on the amount of laundry, similar to the first embodiment described above, and therefore a further detailed description of this will be omitted.

D.2 Rinse cycle (S1050, S1150, S1250):

The rinse cycle of the cold wash cycle may be similar to the rinse cycles of the modes described above and the rinse cycles of other modes, which will be described below. Thus, its further detailed description will be omitted.

D.3 Spin cycle (S1070, S1170, S1270):

The spin cycle of the cold wash mode may be similar to the spin cycles of the modes described above and the spin cycles of other modes, which will be described below. Thus, its further detailed description will be omitted.

E. MODE E (COLOR ITEM MODE):

Mode E will be described with reference to FIG. Mode E may be referred to as a “colored item mode” and may be performed with the ability to more effectively wash colored laundry items. When washing colored items of linen, there may be a problem of repainting, which is caused by the transfer of paints between colored items, the problem of discoloration, the problem of adhering fibers and the problem of the formation of spools. The aforementioned repainting is capable of being carried out at a time when the static friction between the drum and the laundry becomes large. This mode may include a temperature control step configured to prevent repainting by controlling the temperature of the wash water, a colored article washing step configured to drive the drum to prevent fiber adherence and spool formation, and a rinse step. Below these steps will be described in more detail.

E.1 Wash Cycle (First Embodiment) (S1330):

E.1.1 Water supply (S1331):

In the water supplying step, the control component controls the supply of cold water to the tank. Repainting can occur at a higher temperature of the washing water. In the water supplying step, the control component can control the engine to drive the drum into a rocking motion or a saturation movement, or a combination thereof. A water supplying step may be provided for supplying to the tub the water required for washing the laundry and for wetting the laundry that is loaded into the drum in the washing water. As a result, in the water supplying step, the drum is driven to saturate so that wetting of the laundry can be effectively implemented. In addition, at the stage of water supply, the drum can be driven rather into a swaying movement than into a saturation movement. The swinging motion can minimize the movement of the laundry inside the drum compared to other movements to minimize the adhesion of the fibers and the formation of spools, which can be accomplished by the friction force between the laundry items.

E.1.2 Step for measuring water temperature / Heating (S1333):

Once the water supplying step is completed, the control component can measure the temperature of the washing water supplied to the tank. If the measured temperature is equal to the reference temperature or is higher (for example, 30 ° C or 40 ° C), the control component can immediately start the washing phase. If the measured temperature is less than the reference temperature (for example, it is cold water, since the washing water supplied to the water supplying step is cold water), the control component may start a heating step configured to heat the washing water. In some embodiments, the temperature (reference temperature) of the washing water, allowing the washing step to start, can be set to 30 ° C or 40 ° C, since the temperature of the washing water, allowing the washing ability to be maximized, while minimizing repainting, is in the range of 30 ° C to 40 ° C.

In the heating step, the water supplied to the tank is heated using a heater provided on the bottom surface of the tank, or a steam generation device configured to supply steam to the tank.

E.1.3 Wash (S1335):

When it is possible for the temperature to reach the reference temperature (30 ° C or 40 ° C) during the heating step, the control component may start the washing step. In the washing step, the control component can drive the drum, which can minimize the mechanical friction to prevent the fibers from sticking and spools and to provide the desired washing ability. For example, the control component in the washing step of this mode may cause the drum to swing and / or to smooth. Such a smoothing motion and a wiggling motion can be implemented sequentially, and the sequential implementation can be repeated.

With the swaying motion, the drum rotates in both opposite directions, and the laundry is discarded from a location of approximately 90 ° or less with respect to the direction of rotation of the drum. The wiggle movement applies rheostatic engine braking, so that the physical friction applied to the laundry can be reduced as much as possible while maintaining a given level of washing efficiency. As a result, the possibility of adhesion of the fibers and the formation of spools can be minimized, which can occur due to the frictional force between the items of linen or between the linen and the drum.

As mentioned above, during the smoothing movement, the drum rotates at a given speed, allowing the laundry to not be reset by the inner circumferential surface of the drum due to centrifugal force, and then the drum is braked sharply to provide maximum impact applied to the laundry. For this reason, the smoothing movement has an excellent washing ability and is able to compensate for the insufficient washing ability of the wiggle movement. The time period for executing the smoothing movement may be shorter than the period of time for executing the wiggle movement to minimize the possibility of fiber adhesion and spool formation.

E. 1 'Washing Cycle (Second Embodiment) (S1430):

Fig. 14 is a mode diagram of colored objects according to the second embodiment. In contrast to the aforementioned mode according to the first embodiment, the colored object mode according to the second embodiment allows, after the water supplying step (S1431), to realize the step of washing the water temperature and the heating step in the washing step (S1433). If the step of measuring the water temperature and the heating step are implemented before the washing step, the washing time will be unfavorably extended. As a result, this embodiment provides a colored article mode allowing for a reduction in washing time compared to the aforementioned embodiment.

After the water supplying step (S1431), the control component can control the drum in the washing step to drive it into a smoothing motion and / or a swaying motion, and at the same time can determine whether the washing water temperature is a reference temperature (e.g., 30 ° C or 40 ° C ) or higher. If, based on the determination, the temperature of the washing water is equal to or higher than the reference temperature, the control component controls the drum for permanent drive according to the washing step. When the temperature of the wash water is less than the reference temperature, the control component may start a heating step configured to heat the wash water.

The control component may control the drum so that it is not driven by a smoothing motion during the heating step. Those. at the heating stage, the control component drives the drum in a swaying motion, and not in a smoothing motion. The reason why the heating step is not implemented simultaneously with the smoothing movement is described in the above modes, and thus, an additional detailed description will be omitted.

E.2 Rinse cycle (S1450):

The control component may start the rinse cycle after the completion of the wash cycle. During the rinse cycle, the control component can control the drum drive in a saturation movement. The saturation movement rotates the drum at a given speed, preventing the laundry from being discharged from the inner circumferential surface of the drum due to centrifugal force, and at the same time injects washing water into the drum, so that a saturation movement can be applied to wet or rinse the laundry. Also, a saturation movement can generate slight friction between the laundry and between the laundry and the drum. For this reason, the saturation movement allows the laundry to rinse in a relatively short amount of time. To expand the ability to rinse the saturation movement in the rinse cycle, the control component can implement a basic rotation movement.

E.3 Spin cycle (S1470):

After completion of the rinse cycle, a spin cycle may be started, configured to remove wash water from the laundry. The spin cycle of the colored-object mode may be similar to the spin cycles of the modes described above and other cycles that will be described below, and thus its further detailed description will be omitted.

F. F MODE (FUNCTIONAL CLOTHING MODE)

Mode F will be described with reference to FIG. Mode F may be referred to as a “functional clothing mode” and may be arranged to be washed efficiently without damaging the fabric of the functional clothing, including outdoor clothing such as mountaineering clothing and other sportswear. Functional clothes are made and designed for outdoor sports, for example, for mountaineering, swimming, cycling, etc. Functional clothing quickly absorbs sweat and releases absorbed moisture into the environment, and also helps maintain heat from the body. However, this functional clothing is made from a thin synthetic fabric and is less durable than other types of fabrics. The washing mode for functional clothes can be optimized to be more suitable for functional clothes.

First, the user can select the functional clothing mode using the mode selection component 117 (S1510). As soon as the user selects the functional clothes mode, the control component can start the wash cycle, rinse cycle, spin cycle one after another or selectively.

F.1 washing cycle (S1530):

F.1.1 Water supply (S1531):

The control component implements the water supply stage of the wash cycle. The water supply stage supplies the washing water required for washing the laundry. Also, at the water supply stage, the detergent is dissolved in the supplied washing water, and the laundry loaded into the drum is wetted.

F.1.1.1 First water supply (S1533):

The water supplying step includes a first water supplying step implemented for a predetermined time period. In the first water supplying step, the drum may be swayed. As mentioned above, the wiggle movement rotates the drum either in a predetermined direction or in the opposite direction. After turning 90 ° or less from the lowest point of the drum in a predetermined direction and in the opposite direction, the laundry may be discarded. As a result, an alternate clockwise / counterclockwise rotation generates a whirlpool in the wash water, which helps to dissolve the detergent. At the same time, laundry rotated 90 ° or less is discarded, but a strong blow is not applied to the laundry. For this reason, the wiggle movement at the first water supply stage ensures that the detergent dissolves in the wash water, and a strong blow is not applied to the functional clothes. The wiggle movement for a given period of time can be repeated several times.

F.1.1.2 Second water supply (S1535):

After completion of the first water supply within a predetermined period of time, a second water supply can be realized. During the second water supply, the washing water is continuously supplied, and the saturation movement and the wiggle movement can be sequentially implemented. The stages of the first and second water supply can be classified according to a predetermined time. If necessary, the time for each stage can be adjusted according to the amount of linen and other parameters. For this, a laundry amount determination step configured to determine the laundry amount may be provided before the water supplying step.

As mentioned above, the saturation movement rotates the drum at high speed to generate centrifugal force, and the laundry due to the friction force is in close contact with the inner circumferential surface of the drum. Also, due to the frictional force, the washing water passes through the laundry and through the holes in the drum and is discharged from the tank. As a result, when the saturation movement is made, the laundry to be wetted is wetted with washing water. In addition, the washing water simply passes through the laundry, and functional clothes cannot be damaged during the wetting of the laundry. After the saturation movement is realized for a predetermined period of time, the wiggle movement can be realized. As mentioned above, the detergent can be continuously dissolved without damaging the functional clothes. The laundry can be effectively wetted in the wash water by generating a whirlpool and stretching, while the swinging movement in the expanded sense generates a repeated rotation of the drum in a clockwise / counterclockwise direction. For this reason, tangled laundry may be unraveled before washing. In addition, the wiggle movement drops the laundry from a relatively low location, and if the laundry is untangled, damage to the laundry fabric can be minimized. As a result, the combination of saturation and swaying motion can minimize damage to functional clothing and enable efficient wetting of the laundry, dissolution of the detergent, and unraveling of the laundry. Such a sequential combination of saturation and wiggle movements can be repeated several times over a given period of time.

F.1.2 Wash (S1540):

After supplying water to a predetermined water level, the water supplying step is completed, and then the washing step can be started. Since functional clothing is relatively light and thin, essentially the same washing step can be implemented regardless of the amount of laundry in the drum.

F.1.2.1 First wash (S1541):

The washing step may include a first washing step implemented for a predetermined period of time, the drum being driven in a smoothing motion. As mentioned above, the smoothing movement drops laundry from the highest location. As a result, the smoothing movement in the first washing step preliminarily uniformly mixes laundry items and washing water. Also, the smoothing movement impregnates the dirt on the laundry and applies a blow to the laundry to separate the dirt from the laundry by using strong rotation / dropping of the laundry.

F.1.2.2 Second wash (S1543):

After the first washing step, a second washing step may be implemented for a predetermined period of time. In the second washing step, the washing water is heated to wash more efficiently and remove impurities. First of all, the washing water can be heated by a heater provided on the bottom surface of the tank, or a steam generation device configured to supply steam to the tank. As such, in the second washing step, the washing water can be heated to approximately 25 ° C to 30 ° C, preferably to 27 ° C. Functional clothing is made from a thin synthetic fabric structure and may be damaged if the temperature of the heated washing water is excessively high. As a result, washing water having an inherent temperature used in the second washing step can increase the washing efficiency and can prevent tissue damage.

Simultaneously with the heating of the washing water in the second washing step, the drum may be driven by wiggling. The wiggle movement uses dropping the laundry from a relatively low location and uses alternative drum rotation. For this reason, the laundry may sway slightly and to some extent move in the wash water. The wash water during the swinging motion can be uniformly heated for a relatively short period of time, and heat can be transferred to the laundry in sufficient quantities. Also, the wiggle movement can generate friction and shock between the wash water and the laundry, and the shock by dropping can effectively remove dirt without damaging the fabric.

F.1.2.3 Third wash (S1545):

After the second washing step, a third washing step may be implemented for a predetermined period of time. In the third washing step, any remaining dirt can be removed, and a combination of wiggle and smooth motion can be implemented. Although, as mentioned above, the wiggle movement can remove dirt without damaging the fabric, its washing ability is relatively low compared to other movements. As a result, a washing step is added allowing for the use of the strongest blow, while the washing ability of the washing step, which is largely configured from the wiggle movement, can be increased for functional clothes. In addition, a strong blow to the smoothing movement can prevent the fibers from sticking to the laundry. As a result, the third washing step can minimize damage to functional clothes and completely and efficiently separate dirt from the laundry.

F.2 Rinse cycle (S1550):

The rinse cycle of the functional item mode can be similar to rinse cycles of the modes including the standard mode mentioned above, and rinse cycles of other cycles, which will be described below, and thus, its further detailed description will be omitted.

To enhance the overall rinse ability, the rinse cycle can be repeated more often than the standard rinse cycle. For example, a rinse cycle may be implemented at least three times or more. The reason is that in the spin cycle of the functional clothes mode, the drum rotates at a lower rotational speed than in the standard mode, thereby providing a weaker rinse ability. Those. a 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 simultaneously separate the detergent and the dirt together with the wash water from the laundry.

The normal spin phase of the functional mode spin cycle uses the relatively low drum speed and the final rinse ability may be reduced. Thus, the rinse step of the rinse cycle of the functional clothing mode can be implemented three times or more.

F.3 Spin cycle (S1570):

The spin cycle of the functional clothing mode may be similar to spin cycles of the cycles including the standard mode mentioned above and spin cycles of other modes, which will be described later. The normal spin cycle of the spin cycle can rotate the drum at a lower rotational speed than the normal spin phase of the standard mode to prevent damage to the laundry.

G. G MODE (QUICK WASH MODE):

A quick wash mode G, referred to as a “quick wash mode” allowing laundry to be washed in a relatively short amount of time compared to other modes, will be described with respect to FIG. A small amount of laundry typically requires a substantially short wash time compared to a large amount of laundry. In the case of a small amount of laundry, an excessively long period of time may be required to realize a full wash. For this reason, a mode used to wash a small amount of laundry in a short amount of time may be provided. The quick wash mode is based on the standard mode described above with respect to FIG. 7, and in the standard mode, each cycle or operating conditions of each step can be optimized or, if necessary, a predetermined number of steps can be omitted.

First of all, the user can select the quick wash mode (S710B) on the mode selection component 117, and the control component can implement the wash cycle (S730B), the rinse cycle (S750B) and the spin cycle (S770) constituting the quick wash mode.

G.1 washing cycle:

G.1.1 Determination of the amount of laundry:

The control component may start the step of determining the amount of linen for determining the amount of linen (S731B). The step of determining the amount of linen can be implemented before the step of supplying water, which begins after the user selects the quick wash mode. The amount of linen measured in the step of determining the amount of linen of the standard mode, as described above, can be divided into two categories, i.e. large and small quantity, to determine the subsequent cycle or drum movements for each stage and for other operating conditions. In the quick wash mode, the measured amount of laundry can be used to determine the total time of the entire wash, i.e. the total time taken to complete the wash, rinse and spin cycles. Then, in the quick wash mode, the amount of laundry can be distributed into a larger number of categories, for example, three or more categories. If the laundry amount is divided into a larger number of categories, an excellent value for the total washing time (i.e., the total time required to complete the washing, rinsing and spin cycles) can be set for each laundry quantity category. As a result, the total washing time can be controlled depending on the amount of laundry. For this reason, a relatively short time can be suitably applied to a small amount of laundry without compromising the actual washing ability.

For example, the measured amount of laundry can be divided into three categories, including the first, second and third categories, or can be distributed into more than three categories. For example, the first category corresponds to a load of less than about 1.5 kg, and a suitable washing time for the first category can be selected from a range of 25 to 30 minutes, in particular 29 minutes. The second category can correspond to a load of approximately 1.5 to 4.0 kg, and a suitable washing time for the second category can be selected from a range of 35 to 40 minutes, in particular 39 minutes. Finally, the third category can correspond to a load of more than about 4.0 kg, and a suitable washing time for the third category can be selected from a range of 45 to 50 minutes, in particular 49 minutes. Such categories and times can be stored in the memory of the control component as tabular data.

As soon as the laundry amount is determined in the laundry amount determination step, the control component determines which category corresponds to the measured laundry amount, with reference to the stored category table. After that, the control component can set the washing time set for the category corresponding to the measured amount of laundry as the actual washing time.

G.1.2 Water supply / Heating / Washing:

After the above sequence of steps, the control component can sequentially implement the step of supplying water (S733B), the heating step (S740B) and the washing step (S742B) of the wash cycle. The water supplying step, the heating step, the washing step of the washing cycle of the quick wash course are similar to the steps of the washing cycle of the standard mode shown in FIG. 7, and thus their further detailed description will be omitted.

As mentioned above, in the standard mode shown in FIG. 7, a heating preparation step configured to facilitate heating of the wash water can be implemented before the heating step. However, the step of preparing for heating can be a preparatory step, and the movement of the drum in a given period of time can increase the total washing time. As a result, the preparatory steps, for example, the pre-heating step before the heating step, may not be implemented in the case of the quick wash mode. After the water supply mode, a heating step may be started.

G.2 Rinse cycle:

After the washing cycle is completed, a rinse cycle (S750B) may be implemented, configured to remove detergent residues and remaining dirt from the laundry. The rinse cycle (S750B) is similar to the rinse cycle (S750) of the standard mode shown in FIG. 7, and thus a detailed description of the rinse cycle will be omitted.

The first rinse stage, implemented at the initial stage of the standard mode rinse cycle, may include a first drum drive step using a saturation movement that takes a lot of time. In contrast, the drum movement implemented in the rinsing steps (S751B, S756B, S760B) requires a relatively short time, while providing a satisfactory rinse of the laundry. As a result, the saturation movement of the first rinse step provided for in the rinse cycle of the quick wash mode can be omitted to reduce the total washing time.

G.3 Spin cycle

After completing the rinse cycle, the control component may start the spin cycle (S770B). The spin cycle of the quick wash mode is similar to the spin cycle of the standard mode shown in FIG. 7, and therefore, an additional detailed description thereof will be omitted.

The stage of unraveling the laundry, implemented at the initial stage of the spin cycle of the standard mode, implements the movement of the drum, allowing the unraveling of linen. However, such a movement of the drum essentially cannot affect the spin ability. For this reason, to reduce the total washing time, the unraveling step of the laundry may not be implemented in the spin cycle of the quick wash mode.

Although the drum in the normal spin phase of the standard mode can spin at approximately 1000 rpm, the drum in the normal spin phase of the quick wash mode can rotate at approximately 800 rpm. If the rotational speed of the drum increases, the vibration and noise of the drum may become stronger, and the preparation steps are implemented so that the drum reaches the target speed, for example, the step of measuring the eccentricity may be repeated so much that it may require a relatively long operational time. As a result, the target rotation speed of the quick wash mode is reduced compared to the rotation speed of the standard mode, and the time to increase the speed may be limited.

As mentioned above, the quick wash mode can distribute the laundry amount values to predetermined categories, and can set the total wash time values suitable for each category, so that the total wash time of a large amount of laundry, as well as a small amount of laundry, can be reduced by a suitable way. Moreover, compared to the standard mode, the optional stages of the cycles can be omitted to reduce the total washing time. However, most of the drum movements used in the standard cycle are adapted for the quick wash mode, and the desired washing ability can be achieved. As a result, the quick wash mode can wash a small amount of laundry in a short period of time, while the washing ability is maintained.

H. H MODE (SILENT MODE):

Mode H will be described with reference to FIG. Mode H may be referred to as 'silent mode' and may allow noise reduction during washing.

In specific circumstances, the user may not need to feel the noise from the washing machine. For example, when washing at night and / or while sleeping an infant or child, it is desirable that the washing machine operate with less noise. Reducing operational noise can be achieved in various ways. Noise can be effectively reduced by optimizing the control method without increasing production costs. The washing control method for reducing such noise can be implemented in a single mode, namely, a silent mode represented by optimizing operating conditions. Silent mode is based on the standard mode and is implemented by optimizing or neglecting the specific operating conditions of specific cycles or stages of the standard mode. FIG. 16 is a flowchart of various steps of the silent mode method based on the steps of the standard mode. First, the user on the mode selection component 117 may select a silent mode (S1610), and the control component may implement the following sequence of operations.

H.1 washing cycle (S1630):

H.1.1 Determination of the amount of laundry (S1631):

The control component may begin the step of determining the amount of laundry to determine the amount of laundry. The step of determining the amount of laundry has been described above, and its further detailed description will be omitted. The task of the silent mode is to reduce noise and / or vibration, but also maintain the ability to wash. The driving movement of the drum of each stage may vary depending on the amount of laundry.

H.1.1 Water supply (S1633):

Once the user selects silent mode, the water supplying step may begin. The water supply stage supplies washing water to the tank. Also, at the water supply stage, the detergent is dissolved and mixed with washing water, and the laundry loaded into the drum is wetted. In the silent mode water supplying step, the control component can supply a larger amount of washing water to the tub compared to the standard mode water supplying step. The reason that more washing water is supplied will be described in the next washing step.

H.1.1.1 First water supply (S1635):

In the water supplying step, the control component may implement the first water supplying step along with the washing water supply. In the first water supply step, the control component controls the drum to drive torsion.

As mentioned above, the torsion movement continuously rotates the drum in a predetermined direction, and the laundry is separated from the drum after the drum is rotated to a location of 90 ° or less with respect to the direction of rotation of the drum from the lowest point of the drum. When the torsion movement, the drum rotates at a relatively low speed, and the separated laundry rolls along the inner surface of the drum to the lowest point of the drum, and it does not reset to the lowest point. For this reason, rotating the drum and rolling the laundry may generate a predetermined whirlpool in the washing water, which may facilitate the dissolution of the detergent in the washing water. At the same time, the torsion movement involves rolling the laundry along the inner surface of the drum, and therefore, there is no noise from the shock formed by the abrupt drop of the laundry. As a result, the torsion movement in the first water supply step can allow satisfactory dissolution of the detergent in the wash water, while also reducing noise. In the first water supply step, the torsion movement may be repeated several times over a predetermined period of time.

H.1.1.2 Second water supply (S1637):

Once the first water supplying step is completed, the control component may start the second water supplying step. In the second water supply step, the control component can control the drum for sequentially driving the saturation and torsion motion while continuously supplying washing water to the tub. The stages of the first and second water supply can be distinguished from each other according to the corresponding predetermined time, and the time of each stage can be adjusted according to the amount of linen.

As mentioned above, the saturation movement rotates the drum at high speed to generate centrifugal force, and the generated centrifugal force keeps the laundry in close contact with the inner circumferential surface of the drum. Also, due to centrifugal force, the washing water passes through the laundry and through the openings in the drum in order to be discharged into the tank. As a result, when the movement is saturated, the laundry is wetted with water for washing. In addition, the washing water simply passes through the laundry, and the laundry cannot be damaged when wetted in the washing water. After the saturation motion is realized for a predetermined period of time, the torsion motion can be realized. As mentioned above, the torsion movement in the first water supply step can allow satisfactory dissolution of the detergent in the wash water, while also reducing noise. Also, a large surface area of the laundry is in contact with the washing water, rolling along the inner surface of the drum, and thus, the laundry can be soaked in the washing water more efficiently and evenly. As a result, the combination of saturation and torsion movements can minimize noise and provide the ability to achieve effective wetting of the laundry, dissolving the detergent and unraveling the laundry. This combination of saturation and torsion motions can be repeated several times over a given period of time.

H.1.2 Wash (S1635):

After supplying water to a predetermined water level, the water supplying step is completed, and then the washing step can be started.

H.1.2.1 Heating Step / First Wash (S1640):

As soon as the water supplying step is completed, the control component starts the first washing step. The first washing step may include a heating step configured to heat the washing water to a predetermined temperature. In contrast to the heating step and the washing step of the standard mode, the first washing step of the silent mode may include only torsion movement. The torsion movement allows pain to roll along the inner surface of the drum without abruptly dropping the laundry. As a result, since rolling can maximize friction between the laundry and the washing water, as well as between the laundry and the drum, the washing step can effectively remove dirt from the laundry with minimal noise.

As mentioned above, the control component in the water supplying step may supply more washing water than the standard mode water supplying step. For example, the control component may adjust the amount of washing water supplied in the silent washing step so that it is 1.2 times larger than the amount of washing water supplied for the same amount of laundry. An increase in the amount of washing water leads to an increase in the water level inside the drum. When the laundry is rolled in the drum due to the torsion movement at an increased water level, the friction between the washing water and the laundry can be further increased, while the washing ability can be further increased. As such, the torsion movement adapted for the washing step can provide a suitable washing ability, while also reducing noise generation.

If a predetermined amount or more of laundry is loaded into the drum, the slow rotation speed of the drum cannot freely rotate the laundry together with the drum. Even if it rotates together with the drum, a large amount of laundry may have difficulty rolling over the inner surface of the drum, which is related to the volume. As a result, since the torsion movement rotates the drum at a relatively low speed, a large amount of laundry is not able to roll, as was calculated, which leads to the inability to achieve the desired washing ability. For this reason, when washing a large amount of laundry, the washing step can adapt the movement of the drum, which is different from the torsion movement described above.

Those. when the laundry amount measured in the laundry amount determining step is larger than a predetermined reference value, a basic rotation movement instead of a torsion movement can be realized in the washing step. This basic rotation movement continuously rotates the drum in a predetermined direction like a torsion movement, and the drum rotation speed during the basic rotation movement is higher than the drum speed during the torsion movement. As a result, the laundry is separated from the drum after the drum is rotated to a location 90 ° or further with respect to the direction of rotation from the lowest point of the drum. Since the drum rotates at a relatively high speed during the movement of the base rotation, the separated laundry is dropped to the lowest point of the drum, and this is a difference from the torsion movement. As a result, the laundry can be washed with a blow generated by the frictional force between the laundry and the washing water, as well as dropping. Although the base rotation movement generates more noise than the torsion movement, the generated noise may be less than the noise generated by other drum movements, for example, a smoothing movement and a reverse rotation movement, which have a high washing ability. For this reason, the movement of the base rotation can effectively erase a large amount of laundry, while suppressing the generation of noise as much as possible. When the measured amount of laundry is less than the reference value, a torsional motion can be realized as described above.

To facilitate heating of the wash water, a pre-heating step may be implemented before the heating step. However, the step of preparing for heating may include drum movement, and drum movement may generate noise. As a result, preparatory steps, such as the step of preparing for heating before the first washing step, may not be implemented in the washing step of this mode, and the washing water may be heated to a predetermined temperature in the first washing step. The washing water may be heated by a heater or a steam generating device installed in the tank.

H.1.2.2 Second wash (S1642):

The control component may begin the second washing step after the first washing step. In the second washing step, contaminants can be completely and completely removed. Like the first washing step, the second washing step of the silent mode may include only torsion movement. When the torsion movement, the noise generation can be minimized, and, as described above, when the torsion movement, the laundry contamination can be effectively removed. Also, during torsion movement, a larger amount of washing water is supplied as compared to the amount of washing water supplied in the standard mode. For this reason, adaptation of the torsion movement can guarantee a satisfactory washing ability, while also suppressing noise generation.

If the laundry amount is large, the drum is driven by a base rotation. If the laundry amount is small, the drum is driven in a torsional motion, similar to the first washing step described above.

H.2 Rinse Cycle (1650):

As soon as the wash cycle ends, a rinse cycle may begin, configured to remove detergent residues and dirt from the laundry. The rinse cycle is similar to the rinse cycles of the standard mode described above, and therefore, its further detailed description will be omitted.

The first rinse stage, implemented at the initial stage of the standard mode rinse cycle, includes a first drum drive step using a saturation motion that can generate a loud noise. Therefore, the saturation movement is not realized in the rinse cycle of the silent mode. Although the steps of the rinse cycle of the standard mode can adapt various drum movements, the silent mode can only apply torsion motion for the steps of the rinse cycle to reduce noise as in the washing step.

To enhance the overall rinse ability, the rinse stages in silent mode are repeated more times than in standard mode. For example, a rinse cycle may be implemented four times or more. The reason is that the drum rotates at a lower speed during the spinning of the silent mode than during the spinning in the standard mode, thus, the rinsing ability is deteriorated. Those. during the spin cycle, the washing water is typically separated from the laundry by centrifugal force generated by the high rotation speed of the drum, and detergents and dirt are separated from the laundry at the same time as the washing water. However, during the normal spin cycle of the spin cycle of the silent mode, the drum rotates at a lower rotational speed, and thus, the final rinse ability may be impaired. As a result, in the silent rinse cycle, the rinsing steps can be implemented four times or more.

H.3. Spin cycle (S1670):

Once the rinse cycle is completed, the control component can start the spin cycle. The spin cycle is similar to the spin cycles of the standard mode and, therefore, its further detailed description will be omitted.

In the normal spin phase of the silent mode, the drum can be rotated at a lower rotational speed than in the normal phase spin of the standard mode to reduce noise. For example, to reduce noise, the drum can rotate at a given speed, which is 50% of the speed of the normal spin cycle of the standard mode. Those. the drum can rotate at approximately 400 rpm.

I. MODE I (COTTON MODE, SYNTHETIC, MIXED MODE)

Similar to the functional clothing mode described above, modes may be provided for the respective type of laundry items and type of fabric laundry. For example, a cotton mode may be provided that is capable of washing cotton fabric, for example, towels, tablecloths, T-shirts, etc., a synthetic mode or a daily wash mode, capable of washing a synthetic fabric, and a mixed mode, capable of washing mixed types of linen, for example, cotton and synthetic fabrics. The synthetic material may include, for example, polyamide, acrylic, polyester and other types of fabrics.

Cotton fabric and synthetic fabric have excellent characteristics. Those. Cotton fabric is more resistant to abrasion and impact and has a low probability of deformation, unlike synthetic fabric. In addition, a cotton fabric absorbs more water for washing than a synthetic fabric has less chance of wrinkling than a synthetic fabric. However, it is very difficult to always separate items of linen from cotton fabric from items of linen made of synthetic fabric and separately implement the corresponding washing modes for washing them. The reason is that the user usually wears clothes made from cotton and synthetic fabrics at the same time and does not want to wash separate loads of cotton and synthetic clothes. As a result, a washing mode combining the cotton mode and the synthetic mode, i.e. mixed mode.

Mixed mode can be useful for many reasons. For example, if a user separates items of cotton fabric and items of synthetic fabric for washing separately, washing may be disadvantageously delayed until a predetermined amount of laundry is collected, and thus, the soiled laundry may be left unattended for a relatively long time interval. And also, if a small amount of laundry is washed separately, you can uselessly use up electricity. For this reason, the mixed mode, allowing the joint washing of items of linen from traditional types of fabrics, may prevent waste of energy and ignoring the laundry.

In the washing mode provided in accordance with such combinations of various types of fabric shown in FIG. 17, the washing cycle, the rinse cycle, the spin cycle can be varied according to the characteristics of a particular type of fabric. As indicated below, the cotton mode, synthetic mode, and mixed mode, having the correcting operating conditions of each step based on the type of fabric, will be described with reference to the cycles and steps of the standard mode described above. Compared with the standard mode, if necessary, a repeated detailed description will be omitted, and the differences will be described in detail.

As soon as the user selects the cotton mode, synthetic mode or mixed mode (S1710) according to the type of the laundry fabric, the control component may implement a washing cycle (S1730), a rinse cycle (S1750), a spin cycle (S1770), and steps according to the selected cycle.

1.1 Wash cycle

1.1.1 Step for determining the amount of linen (S1734):

The control component can determine the amount of laundry in the washing cycle, and the method for determining the amount of linen of this mode is similar to the above methods, and its re-description will be omitted. The measured amount of laundry can be suitably used in the next step, which will be described in more detail.

1.1.2 Water supply step (S1733):

The control component may implement a water supplying step configured to supply washing water and detergent to the tub or drum and to dissolve the detergent in the washing water. Those. washing water is supplied from an external water supply source together with a detergent. For the initial supply of washing water and laundry detergent, washing water and detergent are supplied to the laundry directly from the inside of the drum. Those. the washing water supply channel may be located in the front upper portion of the drum, toward the inside of the drum, and not in the lower portion of the tub. When the type of detergent is a powder, the dissolution of the detergent cannot be satisfactorily carried out, while the driving movement of the drum of the water supplying step, which will be described later, can satisfactorily dissolve the detergent. As a result, the washing water and the detergent are supplied to the laundry at the initial stage of the washing cycle, and the time required by the washing cycle can be reduced to increase the washing efficiency.

1.1.2.1 Promoting Dissolution of Detergent (S1735):

In the step of facilitating the dissolution of the detergent, the driving movement of the drum may vary depending on the type of fabric of the laundry. For example, a reverse movement may be realized for items of cotton fabric, and a smoothing movement may be implemented for items of synthetic fabric. In alternative embodiments, a reverse rotation movement and / or a smoothing movement may be implemented.

The reverse rotation movement wrinkles / stretches and rubs the laundry by dropping the laundry to generate friction. For this reason, at the initial stage of the washing cycle, an effect similar to the friction effect created by human hands can be suggested. However, this reverse rotation movement can be realized for a fabric that is somewhat resistant to friction, while in the step of facilitating the dissolution of the cotton detergent, the driving movement of the drum may be a reverse rotation movement.

According to the characteristics of synthetic fabric, synthetic laundry items are lighter than cotton laundry items, and synthetic laundry items can absorb less water than cotton laundry items. Also, synthetic laundry items are more likely to be damaged due to friction than cotton laundry items. For this reason, a smoothing movement may be implemented to facilitate the dissolution of the detergent and to prevent damage to the laundry in the step of promoting the dissolution of the detergent. Those. the driving movement of the drum in the step of facilitating the dissolution of the detergent for the synthetic fabric may be a smoothing movement. The smoothing movement applies a maximum drop of dropping to a light synthetic fabric to facilitate the dissolution of the detergent, and an effect similar to that of the user may be offered at the initial stage of the wash cycle.

The driving movement of the drum of the step of facilitating the dissolution of the detergent in the mixed mode may be a combination of the smoothing movement and the reverse rotation movement. Those. the smoothing movement and the reverse rotation movement, which are respectively optimal for cotton and synthetic fabrics, can be combined in such a way as to facilitate the dissolution of the detergent, and the washing effect can be expected at the initial stage of the washing cycle. In this case, the excellent driving movements of the drum are combined, and for this reason, the patterns of moving the laundry and patterns of moving the water for washing can be diverse enough to increase the efficiency of the washing cycle.

1.1.2.2 Wetting laundry (S1736):

At the stage of wetting the laundry standard mode, the drum may be driven by torsion. The torsion movement generates less friction applied to the laundry, in contrast to the aforementioned reverse rotation movement, and the torsion movement is realized after the laundry is wetted. As a result, although friction is applied between the wetted laundry items, there is a slight likelihood of damage to the laundry, and the laundry wetting step implemented by the torsion movement, regardless of the type of fabric of the laundry, can be similarly implemented.

Regardless of whether the fabric is cotton or synthetic, a torsional movement can be realized at the stage of wetting the laundry. Even when the user selects one of a cotton mode, a mixed mode or a synthetic mode, a torsional movement can be realized in the laundry wetting step after the step of facilitating the dissolution of the detergent.

The step of wetting the laundry may include two stages, including the steps of the first and second wetting of the laundry, which are implemented separately. For example, when the laundry wetting step is implemented within 10 minutes, the first wetting step of the laundry can be implemented for 5 minutes, and the second wetting step of the laundry can be implemented for 5 minutes. More precisely, the additional supply of water can be implemented at the stage of the first wetting of the laundry, and the step of the second wetting of the laundry can be implemented as soon as the supply of additional water is completed.

The driving movements of the drum of the first and second wetting stages can be varied for more effective wetting of the laundry and for uniform supply of both detergent and washing water. For example, the driving movement of the drum of the first wetting step of the laundry may be a torsion movement, and the driving movement of the drum of the second wetting step may be a combination of the torsion movement and the saturation movement. Those. at the stage of the first wetting of the laundry, the torsion movement can be realized with a given ratio of the resulting action. In the second wetting step of the laundry after the saturation movement is realized once, the torsion movement is realized four times, and this is one cycle. The cycle can be repeated.

The torsion movement continuously turns the laundry in the lower section of the drum to increase the contact time between the washing water and the detergent. The saturation movement disperses the laundry extensively and allows washing water and detergent to be uniformly supplied to the laundry so that the laundry can be wetted effectively. Typically, approximately 13 minutes are required to complete the wetting of the laundry while the base rotation is moving, although according to this embodiment, the wetting of the laundry may take about 10 minutes.

The driving movement of the drum of the laundry wetting step may vary depending on the amount of laundry. The driving movement of the drum of the first laundry wetting step may vary depending on the determined amount of laundry in the laundry amount determining step. For example, if a certain amount of laundry is equal to a predetermined level or is large, the drum is driven by torsion, as mentioned above. If a certain amount of laundry is less than a predetermined level, the drum may be driven by a combination of smoothing and torsion movements.

The smoothing movement resets laundry after lifting. If the amount of laundry is large, the drop height of the laundry can be reduced. Thus, the smoothing movement is suitable for a small amount of laundry. This smoothing movement may cause damage to the laundry. As a result, in the cotton mode, when the amount of linen is below a predetermined level, at the stage of the first wetting of the linen, a combination of smoothing motion and torsion motion can be realized. When the laundry amount is at a predetermined level or higher, a torsional movement can be realized in the first wetting step of the laundry. In the synthetic mode and mixed mode, for which there is a possibility of damage to the laundry, a torsional movement can be realized at the stage of the first wetting of the laundry, regardless of the amount of the laundry.

In alternative embodiments, a circulation step in accordance with a drum drive may be implemented in the water supplying step. Those. the circulation step can be synchronized with the motor drive, which is configured to drive the drum. The washing water circulating when the laundry is moved by the drum drive can be supplied to the laundry, and the task of the water supplying step can be carried out more efficiently.

According to this embodiment, the step of facilitating the dissolution of the detergent and the step of wetting the laundry are included in the step of supplying water. However, the step of facilitating the dissolution of the detergent and the step of wetting the laundry may be provided regardless of the step of supplying water. In this case, after the water supply, the step of facilitating the dissolution of the detergent and the step of wetting the laundry may be implemented.

1.1.3 Heating (S1741):

The heating step may be modified according to the selected operating condition in this mode. For example, the temperature of the washing water used in the heating step may be set differently depending on the type of fabric of the laundry.

The cotton fabric is somewhat resistant to heat. As the temperature of the washing water increases, more detergent dissolves in the washing water, and this further contributes to the activation of the detergent. As a result, when the cotton mode is selected, in the heating step, the temperature of the washing water can be set to approximately 60 ° C. Such a washing water temperature can be selected by an option component 118 from a range starting from cold water and above to about 95 ° C. As the temperature of the washing water increases, this can further contribute to the activation of the detergent, and the washing ability can be further increased, further increasing, if necessary, the sterilization / bleaching efficiency.

Synthetic fabric can be more strongly / less resistant to high temperature and, thus, synthetic mode or mixed mode has the task to prevent damage to linen by high temperature. When a synthetic mode or a mixed mode is selected, the temperature of the washing water in the heating step can be set to approximately 40 ° C. In synthetic mode or mixed mode, the user can prevent the washing water from choosing a temperature that exceeds 60 ° C to prevent damage to the laundry. For example, when a synthetic mode or a mixed mode is selected, the temperature of the washing water in the heating step may have the highest value of 60 ° C.

The driving movement of the drum of the heating step may be a basic rotation movement, regardless of the mode selected. The reason is that the movement of the base rotation can unravel the laundry while reducing damage to the laundry. As a result, the movement of the base rotation allows the heated wash water stream to be supplied in sufficient quantity to the laundry.

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

1.1.4 Wash (S1742):

The drive movement of the drum of the washing step may be a combination of sequential torsion motion and / or basic rotation motion and / or wiggle movement. The driving movement of the drum of the washing step may vary depending on the selected mode, since both effects must be realized - the effect of protecting the fabric and the effect of increased washing ability.

Those. in the case of washing linen from a cotton fabric, a drive movement of the drum configured to wash the laundry using a strong mechanical effect can be realized. In the case of washing laundry from a synthetic fabric, a drive movement of the drum configured to wash laundry using a relatively small mechanical effect can be realized. The washing step may include one of the steps of the washing cycle, which requires a longer time. As a result, the washing step can be controlled for the most efficient implementation of the wash. Since the required time of the washing step is long, most of the damage to the laundry is capable of being carried out at the washing step.

With this in mind, when the cotton mode is selected, the drum in the washing step may be brought in a combination of a torsion movement and a basic rotation movement. The combination of two different movements applies different patterns of strong mechanical impact on the laundry, and washing efficiency can be increased. Those. according to the characteristics of the cotton fabric, there is little chance of tissue damage. For this reason, a strong mechanical effect is applied to the laundry, and the washing effect can be further enhanced. When the clap mode is selected, at the washing stage, a combination of the saturation movement and the base rotation movement can be realized, with the circulation step synchronized with the drum drive. Since there is little likelihood of damage to the fabric for cotton, the saturation movement can efficiently and evenly supply washing water and detergent to the laundry.

In contrast, when the synthetic mode is selected, the drum during the washing step can be rotated using a combination of wiggle motion and basic rotation motion. The combination of two different movements can increase the washing effect. The wiggle movement gently sways the laundry in the wash water, and therefore, damage to the laundry generated by the frictional force can be minimized. In addition, the time during which the laundry is in contact with washing water can be increased to sufficiently increase the washing effect.

Since the mixed mode is designed for effective joint washing of both cotton and synthetic laundry items, the washing effect should be increased and the damage to the laundry should be reduced as much as possible, regardless of the type of fabric. To accomplish this, if a mixed mode is selected, the drive movement of the drum of the washing step may be a combination of a base rotation motion and / or a wiggle motion and / or torsion motion. Those. a wiggle movement configured to prevent tissue damage may be provided, and a torsion movement configured to increase the washing ability may be provided.

In synthetic mode and mixed mode, the circulation stage can be synchronized with the drum drive in order to allow continuous supply of washing water and detergent to the laundry.

As mentioned above, even if one of the cotton mode, synthetic mode or mixed mode is selected, the driving movement of the drum of the washing step can be adjusted in combination of two excellent movements. This is necessary for the formation of a variety of patterns of mechanical impact and movement of linen, as well as to improve the visual satisfaction of the user.

When the level of contamination of the laundry is selected on the option selection component 118, the ratio of the resultant motor action can be adjusted according to the selected level of contamination. However, an increase in the ratio of the resulting action also increases the time during which the mechanical effect is applied to the laundry. Taking this into account, the ratio of the resulting action of the wash cycle may vary according to the mode selected by the user. Those. the ratio of the resulting action of the cotton regime may be greater than the ratio of the synthetic regime and the mixed regime.

1.1.2 Rinse Cycle (S1750):

As soon as the wash cycle is completed, a rinse cycle may begin. In the rinse cycle, the rinsing steps performed with the possibility of draining the washing water may be repeated after rinsing the laundry using the supplied washing water. The rinse step of the rinse cycle in this mode can be repeated three times or more.

Laundry water can be supplied up to the water level of the rinse cycle, which should be higher than the water level of the wash cycle. Those. washing water can be supplied to a predetermined water level, which is visible from the outside to increase the rinse effect by using enough washing water.

The drive movement of the rinse cycle drum may be a base rotation movement. The basic rotation movement immerses / removes the laundry into / out of the washing water, and this can be repeated. The high water level together with the movement of the base rotation visually notifies the user of a satisfactory rinse. A basic rotation of the rinse cycle can prevent the motor from overheating and also increase the rinse efficiency. Those. the water level of the rinse cycle may be higher than the level of the washing cycle, and the load applied to the drum may be correspondingly increased by the washing water. The smoothing movement, the reverse rotation movement and the wiggle movement repeat the rotation and braking of the engine. As a result, such braking can generate an excessive load on the engine. Also, if the water level is high, the load generated by the washing water can be increased. In a rinse cycle with a high water level, the drive movement of the drum should not be sharply braked to prevent overheating of the engine. Thus, for a rinse cycle, a basic rotation movement adapted to rotate the drum in a predetermined direction may be preferable.

In the rinse cycle, a circulation step for circulating the washing water in the tub to the drum may be implemented. This may generate the effect of visually notifying the user of a satisfactory wash.

1.3 Spin cycle (S1770):

As soon as the washing cycle and the rinsing cycle are completed, a spin cycle may be implemented, configured to remove the washing water from the laundry as much as possible. At the stage of the spin cycle, the spin speed of the drum may vary according to the mode selected by the user, taking into account the percentage of water concentration and residual wrinkling according to the type of fabric.

Cotton fabric has a high percentage of water concentration or absorption capacity, with less chance of wrinkling. Even if wrinkles form on the cotton fabric, these wrinkles are easy to remove. In contrast, synthetic fabric has a low percentage of water concentration or absorption capacity, with a high probability of wrinkling. As a result, in the clap mode, the predetermined speed may be higher than that of the synthetic mode and the mixed mode, and the predetermined speed may be, for example, 1000 rpm or more. Therefore, the spin speed can be changed by the user through the option selection component.

The preset speed of the synthetic mode and the mixed mode can be set in the range from 400 to 600 rpm. Even when synthetic laundry items are squeezed out at a low speed, washing water can quite satisfactorily be removed from the synthetic laundry items, and wrinkling can be prevented. In this case, the spin speed can be changed by the user through the option selection component. In some embodiments, the spin speed is set to a maximum of 800 rpm.

J. J MODE (WOOL MODE):

The washing mode provided according to the type of fabric of linen may rather include a wool mode than a cotton mode, a synthetic mode, and a mixed mode. The wool mode is applied to linen that has less pollution and is more likely to damage the fabric. Those. a wool mode may be provided for washing items of linen from a woolen fabric that are washed manually. When washing with a strong mechanical effect, items of linen made of woolen cloth can be damaged. As a result, in the wool mode, the drum is driven in a predetermined movement, which has a weak mechanical effect, for example, a wiggle movement. Considering the characteristics of the wool fabric, the driving movements of the drum of the wash cycle, rinse cycle and spin cycle of the wool mode may differ from the drum drive in the standard mode.

J.1 washing cycle:

In the wool mode, it is important to prevent damage to the fabric, and the drum can be driven by swaying, made with the ability to gently move the laundry to the right and left in the lower section of the drum. In this case, the water level may be high enough to allow you to see the water level in the drum from the outside. For this reason, the friction between the inner circumferential surface of the drum and the laundry can be minimized, and the touch of the grips on the laundry can be repeated rotating the laundry immersed in water, and this prevents damage to the laundry and allows for careful washing and rinsing. This wiggling motion can minimize damage to the laundry and increase the contact time of the laundry with washing water and detergent to increase the washing effect.

The wool mode is shown in FIG. The wool cycle wash cycle is selected (S1810). At the initial stage of the washing cycle (S1830), washing water and detergent can be supplied to the tub or drum, i.e. a water supplying step may be implemented (S1833). The water supplying step may include a step of facilitating the dissolution of the detergent (S1835) and a step of wetting the laundry (S1836). The detergent dissolution promoting step is configured to facilitate the detergent dissolution in the initial stage of the water supplying step, and the laundry wetting step is configured to sufficiently wet the laundry to prepare the washing step after the water supply is completed. The wetting step of the laundry may be implemented before or after completion of the water supply.

The detergent used in the wool mode may be a neutral detergent and typically is a liquid that does not take long to dissolve in washing water as a powder. Taking this into account, the detergent is supplied to the laundry at the initial stage of the water supply together with the washing water. As soon as the water supply starts, the washing water is supplied to the liquid detergent located in the detergent tray. Laundry water and liquid detergent are jointly supplied to a tank or drum. To supply washing water and liquid detergent more quickly, washing water and liquid detergent mixed together can be sprayed onto laundry placed in the drum. For more efficient dissolution of the detergent, a circulation step may be implemented that is capable of supplying washing water in the tub to the upper portion of the drum.

The drum can be swayed, and then a mild whirlpool is generated in the wash water, which thus helps to dissolve the detergent, while preventing damage to the laundry. As soon as the water supply is completed, the swinging movement and the circulation step can be implemented together to prepare the washing step. In the wetting step, the type of laundry may also be taken into account.

As soon as the step of facilitating the dissolution of the detergent and the step of wetting the laundry are completed, if necessary, a heating step (S1841) may be implemented, configured to heat the washing water. However, in the heating step, the temperature of the washing water can be controlled so that it does not exceed 40 ° C. The heat effect generated if the temperature of the washing water rises significantly will deform the laundry and damage the linen of the woolen fabric. A temperature of 40 ° C does not generate thermal deformation and promotes the absorption of detergent and washing water in the laundry.

The drive movement of the drum of the washing step (S1842) may be a wiggle movement. The washing step requires the longest downtime of the steps of the washing cycle, and in order to prevent damage to the laundry in the washing step, a wiggling movement is used in the washing step. If the application of mechanical action and stops are cyclically applied to the woolen fabric, tissue damage can be generated. This mechanical repetition generates wrinkling of the woolen fabric. To prevent wrinkling, the wiggling movement can be continuously implemented in the washing step.

As mentioned above, the wiggle movement drives the drum and uses rheostatic braking, which does not apply much load to the engine. In addition, the wiggle movement can use a drum drive configured to move the laundry to the right and left by less than 90 ° C. As a result, a large load is not required to lift the laundry. If the drum was continuously driven by a reverse rotation movement and a smoothing movement, an excessive load would be applied to the engine. When the base rotation moves, a lower load can be applied to the engine than when the reverse rotation movement and the smoothing movement, but the laundry rises and discards with the generation of damage to the fabric. Taking this into account, at the stage of washing the wiggle movement is realized.

J.2. Rinse Cycle (S1850):

As soon as the wash cycle ends, a rinse cycle can be implemented. First, medium spin may be implemented. After an average spin, water is supplied to start the rinse, and if necessary, the rinse cycle is carried out several times. Those. after water is supplied and rinsed, the water can be drained again. Typically, the average spin is realized in the middle of the water supply after draining the water.

The average spin unravels the laundry at a relatively low speed. The average spin includes an auxiliary spin configured to unravel laundry at a relatively low rotational speed along with measuring vibration, and a main spin configured to squeeze laundry at a relatively high rotational speed for a predetermined time. The intermediate spin can be realized at about 100 rpm, and the main spin can be realized at about 200 rpm (lower resonant frequency) or at a higher speed.

However, when the wool mode is selected, the average spin may be omitted. Medium spin is the process of removing water for washing from the laundry due to centrifugal force, and a tensile force can inevitably be generated for the laundry. For this reason, wool that is exposed to external influences may be damaged during the spin cycle. To reduce this probability, the average spin may be omitted. For example, the main spin of the middle spin is omitted, and only an intermediate spin can be realized. If all washing water withdrawal processes due to centrifugal force are omitted, the rinse ability may be noticeably impaired. Considering the rinsing ability and damage to the laundry, only an intermediate spin can be realized, and the main spin can be omitted.

The rinse sequence, which includes water supply and draining, can be implemented three times or more, since the remnants of the detergent must be removed from the laundry in a satisfactory manner. The rinse water level may be higher than the water level in the washing step, and the rinsing step may be a circulation step. When a liquid detergent is used, it is generally possible to satisfactorily remove the remaining detergent, since the rinsing step is carried out twice and the average spin is realized. However, in the case of this mode, the main spin of the middle spin is lowered in order to prevent damage to the laundry, and the rinse step to achieve the desired rinse effect can be implemented three times.

The drum drive of the rinse stage to prevent damage to the laundry may be a wiggle movement. The wiggle movement gently pumps the laundry in the wash water and allows detergents that have been soaked in the laundry to be brought into the wash water in such a way that the rinse efficiency can be improved.

J.3 Spin cycle (S1870):

After completing the rinse cycle, a spin cycle can be started. The spin cycle is similar to the spin cycle of the standard mode described above, while the drum speed of the normal spin step for protecting the woolen fabric of linen can be set to 800 rpm or less.

K. K MODE (DELICATE MODE)

The washing mode provided according to the type of fabric of linen may include a delicate mode, as shown in FIG. 19, for washing items of fabric made from a delicate fabric such as silk, a fabric of synthetic fiber, a fabric with elements of plastic, items of linen with metal accessories attached to them, and other similar delicate products. For gentle washing of delicate laundry in a delicate mode, like a wool mode, a drum movement having a relatively weak mechanical effect, such as a wiggle movement, can be realized. As a result, taking into account the characteristics of the delicate fabric, the driving movements of the drum of the washing cycle, the rinsing cycle and the spin cycle of the delicate mode may differ from the driving movements of the drum of the standard mode.

K. 1 washing cycle (S1930):

Like the wool mode, the delicate mode is selected (S1910), and the drum in the washing cycle of the delicate mode is set to swing (S1930), and the washing water is supplied (S1933) to a relatively high water level. Also, the step of facilitating the dissolution of the detergent (S1935) may be similar to the step of facilitating the dissolution of the detergent of the wool mode, since liquid type detergent is usually used to wash the delicate fabric in the delicate mode, similar to the wool mode. However, after the step of facilitating the dissolution of the detergent, a laundry wetting step other than a wool wetting step may be implemented. Wool fabric has a relatively good absorption capacity compared to delicate fabric, and delicate fabric is more susceptible to heat damage than wool fabric. For this reason, the temperature of the wash water that is used to wash the delicate fabric can be set to approximately 30 ° C. Although cold water can be selected, a temperature higher than 40 ° C is usually not selected.

In the laundry wetting step, laundry wetting can be implemented more efficiently by using a saturation movement. A circulation step may also be implemented. After driving rotation of the drum and evenly distributing the laundry inside the drum to increase the surface area of the laundry, the circulation step provides for the circulation of water in the tank with respect to the laundry. Moreover, to immerse the laundry in water and to carefully move the laundry to facilitate wetting of the laundry, a wiggle movement is implemented. To facilitate wetting, the saturation movement and the wiggle movement are repeated in various patterns. However, the driving movement of the drum of the laundry wetting step can only be a wiggle movement.

After the wetting of the laundry is completed, the washing step may start (S1942). The drum movement of the washing step may be a wiggle movement. Delicate underwear may be more resistant to external shock than wool. To achieve a more effective washing ability, the drum movement of the washing step may be a combination of wiggle motion and basic rotation motion, with a relatively high level of washing water.

Alternatively, only the base rotation movement can be realized in the washing step. In this case, the discarded laundry does not collide with the surface of the water in the lower inner portion of the drum due to the high water level. This means that the drop height is reduced. While the impact applied to the laundry is reduced due to the high water level, a whirlpool is generated in the washing water to increase the washing effect. Since such laundry has a relatively low pollution, the time of the washing step can be set relatively short, and the ratio of the resultant action can be set to relatively low. Although only the basic rotation movement is realized, it is possible to prevent damage to the laundry. In the washing step, a circulation step may also be implemented.

K.2 Rinse cycle (S1950):

As soon as the wash cycle is completed, a rinse cycle may begin. As mentioned above, the liquid type detergent can be used in a delicate manner, and the remnants of the detergent can be satisfactorily removed due to the rinse stage, implemented twice. Like the wool mode in delicate mode, the average spin can be omitted. For example, the intermediate spin is not lowered, but only the main spin can be omitted. The drum movement of the rinse cycle can only be the movement of the base rotation. This movement of the base rotation has a distribution effect of the laundry. Those. the movement of the basic rotation allows the surface area of the laundry to make uniform contact with water for washing and to remove the remnants of the detergent in the external environment. In this case, the washing water level may be relatively high. In the rinse cycle, a sway motion may be added to the base rotation motion.

K.3 Spin cycle (S1970):

After completing the rinse cycle, a spin cycle can be started. The spin cycle of this mode may be similar to the spin cycle of the wool mode. The rotational speed of the drum of the ordinary spin phase can be set so as not to exceed 800 rpm. The delicate fabric has a low percentage of water concentration or absorption capacity, and washing water can be discharged evenly, even when the drum rotates at a relatively low rotational speed during the normal spin cycle. Also, in order to prevent damage to the tissue generated by spinning, conventional spinning can be realized at a relatively low speed.

L. L MODE (SPORTS CLOTHING MODE)

Next, the sportswear mode shown in FIG. 2D provided in the washing mode, which is categorized based on the type of fabric of the laundry, will be described. Sportswear mode may be provided for washing laundry made of functional fabric having satisfactory breathability and a satisfactory sweat-absorbing function, for example, mountaineering clothes, tracksuits and sportswear. Like a wool mode or a delicate mode, in a sportswear mode, a drum movement having a weak mechanical effect, for example, a wiggle movement, can be realized. For this reason, taking into account the characteristics of sportswear, drum movements of washing, rinsing and spin cycles provided for in sportswear mode may differ from the drum movements of the standard mode. As soon as the sportswear mode is selected (S2010), the wash cycle (S2030), the rinse cycle (S2050) and the spin cycle (S2070) can be implemented similar to the wool mode and the delicate mode. However, due to the characteristics of sportswear, the washing cycle of the sportswear mode may be different from the washing cycle of the other modes described above.

L.1 Washing cycle (S2030):

Sportswear has water-repellent characteristics that prevent the easy penetration of moisture into the fabric. As a result, compared with other types of fabric, sportswear fabric has a low percentage of water concentration or absorption capacity, and thus, water can be supplied continuously and in sufficient quantity to sportswear fabric in the washing cycle. For this, the driving movement of the drum of the washing cycle (S2030), and in particular the step of supplying water (S2033) provided in the washing cycle, may be different from the movement of the drum of the washing cycles of other modes.

In this mode, the initial driving movement of the drum of the detergent dissolution assistance step (S2035) may be a reverse rotation movement and / or a smoothing movement. For sportswear fabric, there is a small chance of fabric damage compared to woolen or delicate fabric, so sportswear mode can use a driving drum movement that allows for a stronger mechanical effect than the wiggle movement.

The laundry wetting step (S2036) of the sportswear mode may be different from the wool mode or the delicate mode. Although damage to the laundry can be prevented, the wiggle movement is not able to supply enough washing water to the wrapped portion of the laundry due to the water repellent characteristics of the sportswear fabric. Taking this into account, at the stage of wetting the laundry of the sportswear mode, a saturation movement (including a circulation step) can be realized. The saturation movement evenly distributes the laundry inside the drum and evenly supplies washing water to the laundry. In conjunction with the saturation movement, a torsion movement made with the possibility of continuously turning the laundry over can be realized.

L.2 Rinse cycle (S2050):

The rinse cycle of this mode may be similar to the rinse cycles of the standard mode, the wool mode and the delicate mode, and thus its further detailed description will be omitted.

L.3 Spin cycle (S2070):

The spin cycle of this mode may be similar to the spin cycles of standard mode, wool mode and delicate mode, and thus, its further detailed description will be omitted.

M. MODE M:

In the washing machine according to the second embodiment described above with reference to FIG. 2, the tub is directly attached to the body and the drum is provided in the tub. According to a second embodiment, the tank is fixed, and only the drum vibrates. As a result, it is important to prevent the drum from contacting the tub when the drum rotates, and the distance between the tub and the drum may be greater than the distance in the washing machine according to the first embodiment shown in FIG. 1.

When the distance between the tub and the drum is large, the laundry loaded in the drum may not satisfactorily be wetted with water for washing supplied into the tub. For this reason, when water is supplied to the washing machine according to the second embodiment, a circulation pump is driven to efficiently wet the laundry, and the washing water supplied to the tub can be circulated. For example, the circulation pump may be continuously driven, or driven at a predetermined interval when the water supply valve is open.

In the washing machine according to the second embodiment, the drum is connected to the rear wall 230 of the tank. However, the rear wall 230 of the tank is supported by the suspension unit through the bearing socket 400, and not the tank. For this reason, compared with the washing machine according to the first embodiment, which includes a back wall of the tub directly connected to the tub to support the drum, the degree of freedom of the drum provided in the washing machine according to the second embodiment of the invention can be relatively large, and the front the portion of the drum may have an increased degree of freedom.

However, when water is supplied to the tank, the water supply channel and the circulation channel are used to supply washing water from the front portion of the drum. As a result, the laundry placed in the front portion of the drum will be wetted first, and the load on the front portion of the drum is greater than the load on the rear portion. This may cause a downward movement of the front of the drum. If the front portion of the drum moves downward, during the rotation of the drum, vibration noise may increase, and the drum may contact the inside of the tank. As a result, in the washing machine according to the second embodiment, the laundry placed in the front portion and the rear portion of the drum should be uniformly moistened when water is supplied to the laundry. The M mode is called the washing mode applied to the washing machine according to the second embodiment, and more specifically, is the standard mode of the washing machine according to the second embodiment. This mode will be described with reference to FIG.

M.1 washing cycle (S2130):

Fig is a sequence of operations of the mode M. As soon as the user selects a mode on the component selection mode (S2110), the control component can implement the following sequence of operations.

The washing cycle may include a laundry amount determining step (S2131), a water supplying step (S2133), a laundry wetting step (S2135), a heating step (S2137), and a washing step (S2139). In the following description, the laundry wetting step is described as an independent step separate from the water supplying step. However, the laundry wetting step may be included in the water supplying step.

M.1.1 Water supply (S2133):

After measuring the amount of laundry in the wash cycle, the water supplying step may begin. The laundry amount determining step of the water supplying step is described in detail in the above modes, and thus its further detailed description will be omitted.

In the water supplying step, the control component supplies washing water to the inside of the drum. More precisely, the control component opens the water supply valve for supplying washing water to the tank through the water supply channel and the detergent tray. As follows below, embodiments of water supply methods that allow uniform wetting of laundry located in the front portion and rear portion of the drum when supplying washing water to the laundry from the washing machine according to the second embodiment will be described.

According to the water supply method of the first embodiment, when water is supplied in the water supplying step, a circulation pump is driven to circulate the washing water, and the drum is simultaneously driven. The control component may drive the drum in a reverse rotation movement from among the drum movements described above.

In the washing machine according to the second embodiment, the distance between the drum and the tub is larger than the distance between the tub and the drum in the first embodiment. Thus, in the second embodiment, if during the water supplying step the drum is driven in basic rotation (as in the first embodiment), the laundry located in the rear portion of the drum cannot be wetted evenly. Those. since the gap between the drum and the tub is large, when the base rotation moves, the washing water between the drum and the tub cannot be lifted by the rotation of the drum, and in particular, the laundry located in the rear portion cannot be wetted.

As a result, at the stage of water supply of this mode, instead of the movement of the base rotation, the movement of reverse rotation is realized. As mentioned above, the reverse rotation movement rotates the drum at a higher rotation speed (compared to the base rotation movement), and washing water placed between the drum and the tub can be lifted by rotating the drum and then dumped onto the laundry.

In particular, if the rear portion of the drum and the tub is inclined downward in the washing machine according to the second embodiment, washing water disposed in the rear portion of the tub may be supplied to the surface of the laundry by a reverse rotation movement. A reverse rotation movement rotates the drum in a clockwise / counterclockwise direction, abruptly changing the direction of rotation. As a result, a sharp reverse rotation of the drum generates a whirlpool in the wash water, and the laundry placed in the front and rear sections of the drum can be uniformly moistened.

When the water supply valve is open to supply water for washing, the drum is driven and rotated, and the laundry is moved inside the drum according to the drum drive. In this case, the washing water supplied by the water supply channel, which is connected to the front portion of the drum, can be mainly supplied to the laundry transferred to the front portion of the drum. The laundry placed in the front portion of the drum is wetted more quickly than the laundry located in the rear portion of the drum. As a result, according to the second embodiment of the invention of the water supply method, the drum cannot be driven until a predetermined period of time has elapsed after the water supply valve for supplying water has been opened, or until the water level reaches a predetermined level. If the drum is not driven at a predetermined time or is not driven until the washing water reaches a predetermined level, washing water supplied through the water supply channel may accumulate in a lower portion of the tank. The predetermined water level can be determined taking into account the gap between the tank and the drum, and the predetermined time can be set according to the tank and drum capacity and the amount of laundry.

In particular, if the rear portion of the tub provided in the washing machine according to the second embodiment is tilted downward, more washing water can be collected in the rear portion of the tub. Therefore, after a predetermined time has elapsed, the drum is driven and rotated, and the washing water located in the rear portion of the tub can evenly moisten laundry placed in the rear portion of the drum. When the drum is driven in a washing machine according to the second embodiment, the movement of the drum may be a base rotation movement or a reverse rotation movement.

When the water supply valve is open for supplying water according to the second embodiment, and the drum drive is not carried out, it is possible to control the opening / closing of the water supply valve. Those. when the water supply valve is open to supply water, the washing water can have a predetermined pressure due to the pressure of an external water supply source, for example, a water tap, and then the washing water supplied through the water supply channel can be supplied to the front portion of the tank by pressure water so that laundry placed in the front of the drum can be dampened more easily.

As a result, during the water supply in the second embodiment, the water supply valve periodically closes or opens, and is not constantly open, and then the supplied washing water is supplied and stopped so that the predetermined water pressure is satisfactory so as not to directly supply water to drum. A pressure that is satisfactory so as not to supply water directly to the drum means water pressure that allows water to be supplied through the water supply channel so as to fall along the drum, tank or door so as to accumulate in the lower portion of the drum rather than being injected into the drum directly. Water falling along the drum, tank or door may be accumulated in the rear portion of the drum, and the accumulation of washing water in the tank is similar to the description of the second embodiment, so a duplicate description may be omitted.

When the laundry inside the drum becomes tangled during the water supplying step, the laundry may be partially wetted. In particular, the laundry located in the center of a large lump of tangled laundry may not be wet, but only laundry placed on the surface of a large lump may be wetted. If only a certain amount of laundry is wetted, the washing cannot be realized in the washing cycle, and the washing ability may be impaired. As a result, the control component can drive the drum in a saturation movement to uniformly wet the laundry if the laundry is tangled.

Those. the control component opens the water supply valve for supplying water, and also drives a circulation pump for simultaneously circulating washing water. The control component also rotates the drum at a given speed. The predetermined rotation speed is determined by the rotation speed, which allows the laundry to not be reset due to gravity, but to be in close contact with the inner surface of the drum during rotation of the drum. As a result, a predetermined speed can be set based on the centrifugal force generated by the rotation of the drum, which should be greater than the force of gravity during the rotation of the drum. In addition, a predetermined speed can be set below the resonance range (from about 200 rpm to 350 rpm) in which the resonance of the washing machine is generated. If the drum rotates at a speed that is above the resonance range, noise and vibration can be noticeably increased due to resonance. As a result, in this control method, a predetermined speed can be set at about 100 rpm to 170 rpm.

As a result, if the control component rotates the drum at a given speed, the laundry may, due to centrifugal force, be in close contact with the inner surface of the drum. The washing water supplied through the circulation channel and the water supply channel can be distributed according to the rotation of the drum. Distributed washing water can be fed into the drum to the laundry, which is in close contact with the inner surface of the drum so that the laundry can be uniformly moistened.

M.1 2 Washing the laundry (S2135):

After the water supplying step, the control component may start the laundry wetting step. In the laundry wetting step, the control component closes the water supply valve. The control component drives the drum, and washing water is circulated during the circulation pump drive. Although the wetting of the laundry is implemented in the water supplying step, in the wetting step of the laundry, the water supply valve is closed, and the wetting of the laundry can be realized by a drum drive.

In the laundry wetting step of this mode, the control component drives the drum to realize laundry wetting. In this case, the control component may drive the drum in a torsional motion. Since the torsion movement rolls the laundry inside the drum together with the rotation of the drum, the washing water often comes in contact with the laundry, and wetting of the laundry can be safely implemented.

When implementing the laundry wetting step, the control component classifies the laundry wetting step into the first and second laundry wetting steps. The stages of the first and second wetting of the laundry may be driven according to the movements of the drum, i.e. the control component can control the drum movements of the first and second laundry wetting stages, which will differ from each other. The actuation of the circulation pump is as described below.

More specifically, in the first wetting step of the laundry, the control component can drive the drum into one of the torsion and / or smoothing movements. The selection of drive movements of the drum can be determined according to the amount of laundry. Those. if the laundry amount inside the drum is less than a predetermined reference value, for example, if the laundry amount is small, the control component may drive the drum according to the smoothing movement. If the laundry amount is equal to the reference value or is large, the control component may drive the drum according to the torsion movement.

As mentioned above, if the amount of laundry is small, the dropping effect of the laundry for the smoothing movement can be increased. As a result, if the amount of laundry is small during the first wetting step of the laundry, the smoothing movement drops the laundry from the maximum drop height of the laundry to allow water to soak into the laundry. Moreover, if at the stage of the first wetting of the laundry, the amount of laundry is large, a torsion movement is realized. The reason is that the drop height of the laundry of the smoothing movement is not relatively large in the case of a large amount of laundry.

Therefore, in the second wetting step of the laundry, the control component can drive the drum with a predetermined speed, allowing the laundry to be in close contact with the inner surface of the drum, which is not discharged by gravity, i.e. according to the saturation movement. As a result, the drum rotates at a predetermined speed, and the laundry due to centrifugal force can be in close contact with the inner surface of the drum. The washing water supplied by the circulation pump is supplied to the laundry uniformly dispersed on the inner surface of the drum, and thus, the laundry can be uniformly moistened.

In the second laundry wetting step, the control component may implement another drive rotation of the drum after the saturation movement. For example, a control component after a saturation motion may implement a torsion motion. In this case, the saturation movement distributes the laundry to supply water to the laundry, and the torsion movement rolls the laundry to uniformly wet the laundry in the wash water.

M.1.3 Heating (S2137):

After that, the control component starts the heating step. More precisely, the control component drives the drum according to one of the movements of the base rotation and / or torsion and / or swaying, driving the heater provided in the tank for heating the washing water in the tank.

In the washing machine of the second embodiment, the gap between the drum and the tub is larger than the gap of the first embodiment. For this reason, when the washing water is heated by actuating the heater and the drum rotates, only the washing water in the tub is heated, and not the washing water in the drum. As a result, in comparison with heated water, at the washing step, the contaminants of the laundry cannot be uniformly removed, as will be described later, due to the relatively low temperature of the laundry.

For this reason, in the heating step, a control method applied to the washing machine according to the second embodiment for circulating the washing water results in a circulation pump. The heated washing water in the tub is re-fed to the upper portion of the tub by the circulation pump so that the laundry can be heated. However, at the heating stage, the circulation pump can be driven periodically, at predetermined intervals, and not driven continuously. In particular, during the heating step, the circulation pump can be controlled so that the turn-off time of the circulation pump is longer than the turn-on time. If the circulation pump is continuously driven during the heating step, or the turn-on time of the pump is longer than the turn-off time, washing water not heated to a predetermined temperature will circulate and washing water may not be heated to the desired temperature.

If a heater is provided in the tank, it is important to bring the heater when it is covered with water. If the heater is driven when it is not in water, a heavy load is applied to the engine, and the heater may not work properly. As a result, if the heater is activated during the heating step, the predetermined water level that is remote from the heater (hereinafter the reference water level) can be maintained in the heating step. Those. when the water level is lower than the reference level in the heating step, the control component turns off the heater. When the water level rises to a predetermined level or higher by re-supplying water, the control component turns on the heater again (hereinafter referred to as the “turn-off moment”).

However, if the heating step uses the shutdown torque method in the washing machine according to the second embodiment, a large load may be applied to the heater, and the life of the various circuits and the washing machine may be reduced.

Those. the heating step of the washing machine according to the second embodiment of the invention drives the heater to heat, while driving the circulation pump, as mentioned above. As a result, the water level inside the tank cannot be evenly maintained due to the drive of the circulation pump, but can continuously change with a given degree. In this case, the water level inside the tank changes to some extent so that it is below the reference water level. In particular, if the water level inside the tank changes outside the reference level, and if the water level is higher than the reference level, the heater can be turned on and off if the water level is lower than the reference value so that the engine can be turned on / off continuously. Repeated turning on / off of the heater can apply a large load to the heater and many circuits, and can shorten the life of the heater.

As a result, if the water level inside the drum decreases toward the reference level during the motor drive during the heating step of the washing machine according to the second embodiment, re-supply of water can be implemented to prevent the heater from turning on / off again. More precisely, when during the heating step, the water level inside the drum falls below the reference level, the control component stops the drum drive and turns off the circulation pump. At this time, in addition, the water supply valve is opened in order to realize a re-supply of water. The reason the circulation pump and drum are turned off is because it is difficult to accurately measure the water level when the water level changes, when the drum and the circulation pump are driven. In an expanded sense, the engine can be turned off. In this case, when measuring the water level, a repeated supply of water can be realized for a predetermined time or can be realized up to a reference level or above a reference level. The specific water level for re-supplying water may vary according to the type of mode selected at the initial stage of heating.

M.1.3 Wash (S2139):

After the heating step, the control component may implement a washing step configured to drive the circulation pump during the drum drive. In the washing step, the driving movement of the drum may be suitably selected from the movements of the drum, in accordance with a mode selected by the user. For example, the driving movement of the drum of the washing step may be determined similar to the driving movement of the drum of the washing steps provided for the above modes. The circulation pump can be driven for a predetermined period of time to circulate the washing water in the tank.

M.2 Rinse Cycle (S2150):

As soon as the wash cycle is completed after the above steps, the control component can start the rinse cycle. The main rinse cycle may include a rinse-spin step, a water supply step, a drum drive step, and a water discharge step. First, in the rinse-spin step, the control component starts rinsing-spin by rotating the drum at a second rotation speed (RPM 2) (S2151) to remove moisture and residual detergent from the laundry, while rotating the drum from about 500 rpm to 700 rpm min The control component stops the drum and opens the water supply valve to supply rinse water to the tank. The rinse water level can be pre-set according to the mode selected by the user or according to the user's manual settings.

After the water supply, the control component drives the drum to the first rotation speed (RPM 1) for a predetermined interval. In the drum drive step, a control component controls the drive movement of the drum and removes detergent from the laundry. The control component at this stage can drive the drum into one of the movements of the base rotation and / or smoothing and / or reverse rotation and / or torsion and / or rocking described above.

As a result, the control component stops the drum drive and drives the drain pump to drain the rinse water in the tub outside the washing machine (S2153).

The rinse-spin cycle, the water supply step, the drum drive step and the drain step described above can be one cycle of the rinse cycle. The control component according to the mode selected by the user can implement the cycle once or several times. However, a single rinse cycle may include a rinse-spin step. The second rotation speed of the rinse-spin step may correspond to approximately 500 rpm to 700 rpm, as mentioned above, and the rotation speed of such a rinse-spin may correspond to a resonance range (approximately 200 rpm to 350 rpm), which generates the resonance of the washing machine.

As a result, if the laundry placed in the drum is not evenly distributed, then there can be implemented a distribution step configured to distribute the laundry, and the speed of the drum can be accelerated to rinse-spin. The laundry distribution step constantly rotates the drum at a given speed in a clockwise and / or counterclockwise direction. After the laundry distribution step, the eccentricity level of the drum is identified. If the eccentricity level of the drum is less than a predetermined value, rinse-spin may be implemented. If the eccentricity level is equal to or above a predetermined level, the laundry distribution step may be repeated. Since the laundry distribution step is implemented before the rinse-spin step, the rinse cycle time can be increased. In particular, since the laundry distribution step is repeated, the rinse cycle time can be significantly increased, and the time consumed by the rinse cycle cannot be accurately predicted.

Hereinafter, in order to solve the aforementioned problems, a method for controlling a rinse cycle will be described, allowing a reduction in the total time consumed by the rinse cycle.

As shown in FIG. 21, the rinsing cycle of the washing machine according to the second embodiment may include a washing water supply step, a drum driving step (S2151), and a water draining step (S2153). Compared to the first embodiment, the rinse cycle according to the second embodiment omits the rinse-spin step. Since the rinse-spin step is omitted, the rinse cycle time can be reduced by the time of the rinse-spin step, and the laundry distribution step may not be necessary, thereby preventing a noticeable increase in the rinse cycle caused by the repeat of the laundry distribution step. Although due to the omitted rinse-spin step, the rinse cycle time is reduced, the spin rinse step, configured to remove detergent residues by rotating the drum at a relatively high speed, is omitted, and then it will be difficult to satisfactorily remove detergent residues.

As a result, in the rinse cycle control method according to the second embodiment, the drum rotates at a second rotation speed (RPM 2) for about 1 to 3 minutes, and does not stop at the water draining step. The second rotation speed is determined as a predetermined speed, which allows the laundry to lie on the inner surface of the drum due to centrifugal force and not be reset during rotation of the drum. The second rotation speed can be set by centrifugal force generated by the rotation of the drum, which should be greater than gravity. Also, the second rotation speed can be set so as to be below the resonance range of the washing machine. If the drum rotates within the resonance range, resonance can markedly increase noise and vibration. Therefore, the second rotation speed can be set at approximately 100 to 170 rpm.

As a result, the draining step rotates the drum at a given speed, and the laundry, thus, can be in close contact with the inner surface of the drum due to centrifugal force in order to remove residual detergent from the laundry. To compensate for the omitted rinse-spin step, the drain step rotates the drum at a second rotation speed to prevent deterioration of the rinse ability.

At the stage of rotation of the drum at the second speed of rotation (a predetermined speed that allows the laundry to be in close contact with the inner surface of the drum) if the water in the tank is drained, all stages of the drain can be implemented before the rinse cycle. Those. even if the water is drained in the washing cycle, the step of rotating the drum at a given speed can be implemented.

M.3 Spin cycle (S2170):

The spin cycle of this mode can be similar to the spin cycles of other modes, for example, the spin cycle of mode A. Thus, its additional detailed description will be omitted.

The M mode described above can be applied in the washing machine according to the second embodiment. However, mode M can also be applied to the washing machine according to the first embodiment. Those. mode M can be applied to any washing machines according to the first and second embodiments.

N. TIME MANAGEMENT OPTION

Next will be described the time management option. Usually, when choosing a particular mode, the selected mode starts to operate based on a predetermined algorithm, and the work ends after a predetermined amount of time. The operating time required to implement the mode may be the total operating time required by the individual cycles constituting the mode. This total operating time may be displayed on the display component 119.

Under specific circumstances, the operating time can be very long. For example, if the user must leave after 1 hour, and the predefined time is 1 hour 20 minutes, this time is 20 minutes longer than the desired time for the user. In contrast, for severe contamination, the washing process, which takes 1 hour and 20 minutes, is not sufficient to wash the laundry. To solve these problems, a washing machine and its control method that allows time management is provided.

The washing machines described above may include a time management option provided for time management. Those. the operating time of a particular mode can be increased or decreased by the option component. More precisely, the user can select the time saving option through the time management option. Alternatively, the user can select the intensive wash option through the time management option. If no such options are selected, the operation can be implemented according to a predetermined mode. This time management can be implemented before the start of the wash cycle and after selecting the operating mode.

For example, when the user selects the time saving option, if the operating time of the clap mode is 120 minutes, the required operating time can be reduced, for example, to 100 minutes. When the user selects the intensive wash option, the operating time can be increased to 140 minutes to provide the effect of cleaning heavily soiled items. There may be a certain difference between a predetermined time and the actually required time.

The required time for the wash cycle and / or rinse cycle can be varied according to the choice of time saving option. Those. a cycle in which the required operating time is changed / adjusted may be different, depending on the mode selected. For example, in the case of cotton mode, synthetic mode and mixed mode, it is important to increase the washing ability. For this reason, the required normal wash cycle time cannot be changed even if the time save option is selected. Thus, during correction, the required time of one of the components of the rinse cycle can be taken into account.

The rinse cycle repeats the water supply, draining and spinning. Rinsing can be carried out twice, three times or four times. Spin can be implemented in the same sequence of the spin cycle, but with a rotation frequency and main spin time less than that of the spin cycle. As a result, when the time saving option is selected, the main spin of the rinse cycle may be omitted.

When the time saving option is selected, the step of determining the amount of laundry depending on the selected mode may be omitted. For example, when a wool mode or a sportswear mode is selected, the amount of this particular fabric is relatively small. If such tissue items become dirty, the user has a tendency to wash them immediately. As a result, very rarely such types of laundry are washed in large quantities at a time in any mode. With this in mind, the step of determining the amount of laundry may be omitted when the wool mode, delicate mode or sportswear mode is selected.

In contrast, when the intensive wash option is selected, the number of rinse implementations in the rinse cycle or the required wash cycle time can be increased, or both can be increased.

This time management option satisfies the task of a given mode and allows the user to conveniently manage time.

IV. DRUM DRIVING ACCORDING TO THE MODE AND STAGE OF THE MODE

Next, the driving movement of the drum according to each cycle of each mode will be described. As mentioned above, the drive movement of the drum includes a combination of the direction of rotation of the drum and the speed of rotation of the drum, and varies the direction of the drop and the drop point of the laundry placed in the drum to form excellent movements of the drum. These drive movements of the drum may be implemented under engine control.

Since the laundry is lifted by the grip provided on the inner circumferential surface of the drum, during rotation of the drum, the rotation speed and the direction of rotation of the drum are controlled to modify the impact applied to the laundry. Those. mechanical stresses, including friction between items of laundry, friction between laundry and water for washing and shock due to dropping can vary. In other words, when washing the laundry, the level of impact and friction of the laundry may vary, and the level of distribution of the laundry or the level of turning the laundry may also vary.

As a result, the driving movement of the drum may vary according to each cycle forming different washing modes, and to each specific step forming each cycle so that the laundry can be washed with optimized mechanical action. For this reason, washing efficiency can be increased. In addition, separately taken constant drive movement of the drum may lead to excessive washing time. Next, the driving movement of the drum for each cycle will be described.

Washing cycle:

The washing cycle includes a step of determining the amount of laundry, a step for supplying water and a washing step. The water supplying step includes a step of facilitating the dissolution of the detergent, configured to dissolve the detergent, and a step of wetting the laundry, configured to wet the laundry. The step of facilitating the dissolution of the detergent and the step of wetting the laundry may be provided independently, separately from the water supplying step. Additionally, a heating step may be provided according to each mode.

1. 1. Determination of the amount of linen:

To implement the stage of determining the amount of linen, electric currents are measured, which are used to rotate the drum. In this case, when the drum rotates in a predetermined direction, at the step of determining the amount of laundry, the current consumption can be measured, and the drum can be driven according to a single rotation motion, for example, a basic rotation motion.

1. 2. Water supply:

In the water supplying step, washing water is supplied together with the detergent, and the step of dissolving the detergent can be implemented. To increase the efficiency of the wash cycle, the dissolution of the detergent can be effectively completed at the initial stage of the water supply stage. To quickly dissolve the detergent in the wash water, a movement made with the ability to apply strong mechanical stress may be effective. Those. a strong mechanical effect is applied to the washing water to more efficiently dissolve the detergent in the washing water. As a result, in the step of facilitating the dissolution of the detergent, the drum rotates according to the smoothing movement and / or the reverse rotation movement. As mentioned above, the smoothing movement and the reverse rotation movement rotate the drum at a relatively high speed, applying a sharp braking of the drum to change directions, and a strong mechanical effect can be provided. At this stage, it may be possible to combine the smoothing movement and the reverse rotation movement.

At the stage of promoting wetting, it is important to soak the laundry in washing water mixed with a detergent. In this case, the driving movement of the drum may be a saturation movement. Alternatively, a saturation movement and a torsion movement can be sequentially implemented. The torsion movement continuously turns the laundry in order to enable the washing water located in the lower portion of the drum to make uniform contact with the laundry and to ensure proper wetting of the laundry. The saturation movement disperses the laundry during the rotation of the drum in order to bring the laundry into close contact with the inner circumferential surface of the drum, while the washing water is simultaneously injected into the drum so that the washing water can be discharged into the tub through the laundry and through the openings drum due to centrifugal force. As a result, the saturation movement increases the surface area of the laundry and allows washing water to pass through the laundry. For this reason, it is possible to achieve the effect of a uniform supply of washing water to the laundry. Also, in order to use this effect, at the stage of assisting the wetting of the laundry, two driving movements of the drum are sequentially repeated, i.e., the saturation movement and the torsion movement. If the laundry amount is equal to a predetermined level or is large, the wetting effect of the laundry may be worsened by a torsion movement that has a relatively low drum rotation speed, and thus, instead of a torsion movement, a basic rotation movement having a relatively high drum rotation speed can be implemented.

However, the step of facilitating the dissolution of the detergent or the step of wetting the laundry of the water supplying step can be classified according to the driving movements of the drum when the washing water is supplied continuously. As a result, it is difficult for the user to distinguish the above steps in the water supplying step. From the user's point of view, it seems that the drum at the stage of water supply is driven according to one of the torsion and / or basic rotation and / or smoothing and / or reverse rotation movements, or a combination of two or more of these movements.

There may be modes configured to prevent damage to the laundry fabric according to the type of laundry fabric. Also, according to such a mode, there may be modes configured to suppress the generation of noise when washing the laundry. When the drum is driven according to movement allowing the application of strong mechanical stress during the water supplying step, it is usually difficult to avoid damaging the laundry fabric or generating noise. As a result, movements are provided for at the water supply stages that allow the reduction of noise generation as much as possible, or that prevent damage to the laundry. In such modes, the effect of dissolving the detergent and the effect of wetting are achieved in such a way that in these modes, the drum can be driven by swaying, or the time of the torsion movement can be increased.

The wiggle movement can minimize the movement of the laundry inside the drum compared to other movements, and it can minimize the tissue damage generated by the friction of the laundry and the friction between the laundry and the drum. In addition, the torsion movement includes rolling the laundry along the inner surface of the drum, and does not generate a shock due to the abrupt drop of the laundry.

If the dissolution of the detergent and the wetting of the laundry are realized at the stage of water supply, at least at a predetermined stage, a circulation step may be provided that is capable of circulating the washing water. Such a circulation step can be implemented at the entire water supply stage or at a predetermined stage of the water supply stage.

1.3. The heating:

At the heating stage, a driving movement of the drum may be provided, configured to transfer heat generated by the heater to the laundry during heating of the water. In the heating step, the drum is driven according to a base rotation movement configured to continuously rotate the drum in a predetermined direction. If the direction of rotation of the drum changes, a whirlpool is generated in the wash water, and heat transfer efficiency may be impaired. If the laundry amount is below a predetermined level of the laundry amount, the drum is driven by torsion. If the laundry amount is equal to a predetermined level of the laundry amount or is large, the drum is driven by a base rotation. The torsion movement can satisfactorily heat the laundry if the amount of the laundry is below a predetermined level. If the laundry amount is equal to or above a predetermined level, a basic rotation movement adapted to rotate the drum at a relatively high speed may be suitable.

1.4. Wash:

The washing step may take the longest wash cycle time. In the washing step, the contaminants of the laundry can be substantially removed, and the driving movement of the drum of the washing step can be a movement allowing the laundry to be moved in different patterns. For example, the drive movement of the drum of the washing step may be one of either a combination of a smoothing motion and / or a base rotation motion and / or a torsion motion. This combination of movements can apply a strong mechanical effect to the laundry. The combination of these movements can be especially effective in the case of a small amount of linen.

The driving movement of the drum of the washing step may be a combination of the movement of saturation and the movement of the base rotation. Such a driving movement of the drum can continuously supply washing water to the laundry to increase the washing efficiency and can evenly apply mechanical action to the laundry to increase the washing efficiency. This combination can be effective with a large amount of linen.

A heating step is provided before the washing step, wherein washing water can be heated in the washing step to increase the washing efficiency. When heating the washing water, the driving movements of the drum can be combined. For example, if the heater provided in the tank is driven to heat the washing water, the drum may be driven according to a driving movement of the drum that does not have sudden braking.

As mentioned above, in modes configured to prevent tissue damage and suppress the generation of noise during the washing step, movement may be provided allowing a relatively weak mechanical effect on the laundry to be applied. For example, in the washing steps of the above modes, a wiggling movement can be implemented to reduce noise generation and prevent tissue damage. As a result, the running time of the wiggle movement may be longer than that of other mode movements. If the washing step is carried out only by the swaying movement, the washing efficiency may be impaired, and in addition, a movement having a strong mechanical effect may be provided. The operating time of a movement having a strong mechanical effect can be set shorter than the time of a movement having a weak mechanical effect.

2. Rinse cycle:

In the rinse cycle, the steps of water supply, drum drive and draining are repeated to rinse in order to remove contaminants on the laundry or residues of detergent. As a result, the drive movement of the drum of the rinse cycle may be a movement allowing the generation of an effect similar to friction. For example, the drive movement of the rinse drum may be a reverse rotation movement and / or a wiggle movement. Both the reverse rotation movement and the wiggle movement to increase the rinsing ability have the effect of continuous friction and rolling of the laundry in the wash water.

When a drum is provided in the rinsing step, a circulation step configured to circulate the wash water in the tub inside the drum and the saturation movement can be implemented together. Those. washing water is injected into the drum and the laundry is rinsed with running water. The saturation movement generates a strong centrifugal force and can separate detergents and soiling of the laundry along with water from the laundry.

In the rinse cycle, the washing water can be drained together with the bubbles through the use of mechanical action applied to the laundry during draining and / or intermediate spinning. As a result, the drum is driven into a smoothing movement or a basic rotation movement. When dropping the raised laundry, the washing efficiency can be increased, and the bubbles can be safely removed. The driving movement of the drum may vary depending on the amount of laundry. Those. in the case of a small amount of laundry, a smoothing movement is implemented to effect dropping from a maximum height. In the case of a large amount of linen, a basic rotation movement is realized.

As mentioned above, in the modes selected to prevent tissue damage or to inhibit the generation of noise, movement may be provided in the rinse cycle allowing a relatively weak mechanical effect to be applied to the laundry. For example, wiggle motion may be provided in rinse cycles. In the mode selected to reduce the washing time, it is possible to reduce the rinse cycle time. For example, the saturation movement consumes a relatively large amount of time, and thus, at the stage of driving the rinse drum, the saturation movement can be omitted when the mode with decreasing the total washing time is selected.

3. Spin cycle:

In the spin cycle, the drum rotates at a predetermined speed or higher to remove moisture contained in the laundry, and the spin cycle may include an unraveling step of the laundry and an eccentricity measurement step for accelerating the rotation of the drum to a predetermined speed. A suitable drive movement of the drum may be selected according to the task of each step. For example, at the stage of unraveling laundry, it is preferable to apply a relatively strong mechanical effect on the laundry. If a movement allowing a strong mechanical impact is provided before the rinse cycle, even a movement having a weak mechanical effect is sufficient. Also, for accurate measurement of the eccentricity in the step of measuring the eccentricity, a driving movement of the drum configured to continuously rotate the drum in one direction may be suitable.

V. NEW MODES

In the description of the different modes, each mode includes a washing cycle, a rinse cycle and a spin cycle. However, according to the user's choice, it is possible to omit one cycle from each mode. Those. it is possible to omit the washing cycle from mode A (standard mode), or to lower the rinse cycle from mode B (highly contaminated mode), or to lower the spin cycle from mode C (fast boiling mode). In an expanded sense, one of the cycles provided in each mode can be defined as an auxiliary mode. For example, the wash cycle of mode F (functional clothing mode) may be set as a separate new mode. In this case, it may be referred to as 'washing functional clothes'. Instead of a wash cycle, rather the rinse cycle or spin cycle provided in each mode can be set as a new mode.

Although the wash cycle, rinse cycle and spin cycle are described in a specific order to explain each of the modes, such cycles of one mode can be combined with cycles of another mode to create a new mode. For example, the rinse cycle and the spin cycle of mode A (standard mode) can be combined with the washing cycle of mode B (heavy soiling mode). Alternatively, each cycle can be obtained from other modes. For example, the rinse cycle of mode A (standard mode) and the spin cycle of mode M can be combined with the wash cycle of mode B (heavy soiling) and set as the new mode. In this case, the steps performed with the ability to join the cycles can be adjusted or changed in a suitable way.

Additionally, the new mode can be implemented based on actions and conditions appropriate for washing clothes. In FIG. From 22 to 25, the stages, results and conditions used to determine the movement of the standard mode, the mode with intensive movements (heavy pollution mode, fast boiling mode and cold wash mode) and the mode with careful movements (colored objects mode, delicate mode or wool mode) are illustrated ) To create new programs, based on the desired effects and conditions, the movements of the drum can be selected among the movements of the standard mode, the mode with intensive movements and the mode with careful movements. The present disclosure and features may be further applied to the movement of the dryer drum, which, for example, is disclosed in US Publication Nos. 2009/0126222, 2010/0005680 and 2010/0162586 of US applications, the entire disclosure of which is incorporated herein by reference.
