The laundry administration 210 is a stroke for removing contamination from the cloth by rotating the drum 124 after wetting the laundry water mixed with the laundry detergent in the cloth. In the laundry method according to an embodiment of the present invention, the washing administration 210 proceeds in the order of water supply 211, washing 212, podis dispersion 213, drainage 214, and simple dewatering 215.

When the laundry administration 210 is started, the control unit 141 displays the washing icon on the progress display of the display unit 114a shown in FIG. 6 to indicate that the laundry administration is started.

The water supply 211 supplies washing water into the tub 122 from an external water source. When the control unit 141 opens the water supply valve 131 during the water supply 211, the washing water flows from the external water source to the detergent box 133 through the first water supply passage 132. In the detergent box 133, the washing water is mixed with the laundry detergent and introduced into the tub 122 through the water supply pipe 134. Washing water in the detergent box 133 may be mixed with bleach.

In the water supply 211, the washing machine mixed with the laundry detergent is evenly soaked in the cloth so that the control unit 141 drives the driving unit 113 so that the drum 124 rotates. The water supply 211 proceeds until the wash water fills up to the target water level, and the target water level is determined by the control unit 141 according to the amount of cloth (hereinafter referred to as 'amount') or the selected course measured before the water supply 211. do. The water level of the wash water is preferably measured by a water level detection device (not shown).

Amount can be measured in various ways. In this embodiment, after the driving unit 113 rotates the drum 124 at a constant speed for a predetermined time, the control unit 141 measures the deceleration time. The longer the deceleration time of the drum 124, the higher the level of the quantity of the gun.

When the wash water flows into the tub 122 to the target water level, the controller 141 blocks the water supply valve 131 to finish the water supply 211.

The laundry 212 rotates the drum 124 containing the cloth soaked with the washing water mixed with the laundry detergent. When the washing machine 212, the control unit 141 drives the driving unit 113, the driving unit rotates the drum 124, the foam in the drum is lifted up by the lifter 125, and falls off, friction between the foam and drop of the fabric This eliminates contamination of the fabric.

During washing 212, the control unit 141 may control the driving unit 113 to rotate the drum 124 at various speeds or directions, and in this embodiment, the drum is rotated in a predetermined direction at about 40 rpm. Drop repeatedly. In order to prevent overheating of the driving unit 113 during washing 212, the control unit 141 may allow the driving of the driving unit to be rested at several seconds to several minutes apart.

Steam may be injected into the drum 124 during the washing 212 according to the washing course or the user's choice. When washing 212, the controller 141 may operate the pump 136 to circulate the washing water into the tub 122 along the circulation passage 137.

Foam dispersion 213 is a drum 124 to disperse the cloth by repeating the acceleration and deceleration. When washing 212 or rinsing 222, the fabric is deviated to one side due to entanglement of the fabric and the like, causing an eccentricity in which one side becomes heavy based on the center of the drum. Since the eccentricity of the gun causes noise and vibration during the main dehydration 231, the gun dispersion 213 is required to evenly distribute the gun dewatering stroke 230.

The drain 214 discharges the washing water in the tub 122 to the outside of the cabinet 111. The control unit 141 operates the pump 136 to discharge the washing water in the tub 122 to the outside along the drain passage 138 at the time of drainage 214.

The simple dewatering 215 is to rotate the drum 124 at high speed so that the wash water soaked in the cloth exits. When the simple dewatering 215, the control unit 141 drives the driving unit 113 to rotate the drum 124 at high speed so as to be attached to the inner wall of the carriage drum and dehydrated by centrifugal force. Since the simple dehydration 215 does not need to be dehydrated to the extent that the fabric is dried, the drum 124 is preferably rotated at 108 rpm, which is a speed at which the foam is attached to the inner wall of the drum.

In the simple dewatering 215, the control unit 141 operates the pump 136 to discharge the washing water in the tub 122 to the outside along the drainage flow path 138.

The rinsing stroke 220 is a stroke for removing the residual laundry detergent of the fabric by rotating the drum 124 after wetting the wash water mixed with the fabric softener. In the washing method according to an embodiment of the present invention, the rinsing stroke 220 is in the order of water supply 221, rinsing 222, drainage 223, simple dewatering 224, water supply 225 and rinsing 226. Proceed. In this embodiment, the rinses 222 and 226 are repeated twice and may not be repeated or may be repeated several times depending on the embodiment.

When the rinsing stroke 220 is started, the control unit 141 displays a rinsing icon on the progress display of the display unit 141a shown in FIG. 6 to indicate that the rinsing stroke is started.

The water supply 221 supplies the washing water into the tub 122 from the external water source similarly to the water supply 211 of the washing stroke 210 described above. In the case of the water supply 221, the washing water introduced through the first water supply passage 132 may be supplied to the tub 122 through the water supply pipe 134, and the washing water introduced through the second water supply passage 139 may be removed. It is also possible to spray toward the fabric housed in the drum 124 through the two injection nozzles (129). Therefore, the controller 141 controls the water supply valve 131 to supply the washing water to the first water supply passage 132 and / or the second water supply passage 139 according to a set algorithm.

It is preferable that the fabric softener is not mixed with the wash water at the water supply 221 and the fabric softener is mixed with the wash water at the last water supply 225 of the rinsing stroke 220 which will be described later. The control unit 141 drives the driving unit 113 so that the washing water is evenly wetted with the cloth, and the drum core 124 rotates.

Rinse 222 is to rotate the drum 124 is accommodated in the cloth soaked with wash water. When the driving unit 113 rotates the drum 124 during the rinsing 222, the cloth in the drum is dropped after being lifted up by the lifter 125, and the residual laundry detergent and contamination of the cloth due to the friction between the cloths and the dropping of the cloths. Is removed.

In the rinsing 222, the control unit 141 may control the driving unit 113 to rotate the drum 124 at various speeds or directions. In this embodiment, the drum 124 is rotated in a predetermined direction at about 40 rpm. The gun in the drum is repeatedly dropped. In the rinsing 222, the control unit 141 operates the pump 136 to circulate the washing water into the tub 122 along the circulation passage 137.

The drain 223 discharges the washing water in the tub 122 to the outside of the cabinet 111, similarly to the drain 214 of the washing stroke 210 described above.

The simple dewatering 224 is similar to the simple dewatering 215 of the washing stroke 210 described above, and the controller 141 drives the driving unit 113 so that the washing water soaked in the cloth exits the drum 124 at high speed. It is to let. When the simple dewatering 224, the drum 124 may rotate at about 800 rpm, which is faster than the simple dewatering 215 of the washing stroke 210.

The water supply 225 supplies washing water from the external water source into the tub 122 in the same manner as the water supply 221 described above in order to repeat the rinsing 226 again. Washing water in the water supply 225 is preferably mixed with the fabric softener in the detergent box 133 is introduced into the tub 122. When the water supply 225, the washing water mixed with the fabric softener is evenly soaked in the fabric, and the control unit 141 drives the driving unit 113 so that the drum 124 rotates. As in the rinsing 222 described above, the wash water may be supplied through the second injection nozzle 129.

The rinse 226 rotates the drum 124 containing the cloth in which the washing water is soaked, similar to the rinsing 222 described above. However, the washing water mixed with the fabric softener during rinsing (226) acts on the fabric to soften the fabric.

Fossil dispersal 227 is similar to the dispersal 213 of the washing stroke 210 described above. The drum 124 repeats acceleration and deceleration to disperse the foam.

A detailed description of the foam dispersion 227 will be described later with reference to FIG. 7.

The dehydration stroke 230 is a stroke for dewatering the gun by rotating the drum 124 at high speed. In the laundry method according to an embodiment of the present invention, the dehydration stroke 230 includes the main dehydration 231.

When the dehydration stroke 230 is started, the controller 141 displays the dehydration icon on the progress display of the display unit 114a shown in FIG. 6 to indicate that the dehydration stroke is started.

The main dehydration 231 is to rotate the drum 124 at a high speed so that the wash water soaked in the cloth exits. If the control unit 141 rotates the drum 124 at high speed during the main dehydration 231, the control unit 141 is attached to the inner wall of the carriage drum and rotates to dehydrate the carriage by centrifugal force. The drum 124 during the main dewatering 231 may rotate at a speed of 1000 rpm or more, which is faster than the simple dewatering 215 of the washing stroke 210 or the simple dewatering 224 of the rinsing stroke 220.

When the main dewatering 231, the control unit 141 operates the pump 136, it is preferable that the washing water in the tub 122 is discharged to the outside along the drain flow passage (138).

When the drum 124 rotates at a high speed in the main dehydration 231, the drum may repeat the acceleration and deceleration to disperse the fabric. However, if the foam is sufficiently dispersed in the foam dispersion 213 of the washing stroke 210 and the foam dispersion 227 of the rinsing stroke 220 may be omitted.

After the main dehydration 231, drying may be performed to supply hot air into the drum 124 to dry the fabric.

7 is a view showing podis dispersion in the laundry method according to an embodiment of the present invention.

The foam dispersion 227 disperses the foam by repeatedly accelerating and decelerating the drum 124 before the dehydration stroke 230 in the state in which the washing water is accommodated in the tub 122 after the rinsing 226. The washing icon lights up in the progress indication of the display unit 114a at the time of dispersing 227 to indicate that the rinsing stroke 220 is performed.

The foam dispersion 227 accelerates and decelerates the drum 124 at 70 to 80 rpm, which is a speed at which the foam starts to adhere to the drum inner wall. The controller 141 measures the amount of eccentricity based on the speed change characteristic of the drum 124 at the time of foam dispersion 213. For example, the controller 124 may measure a quantity based on the deceleration time of the drum when the drum 124 is decelerated, and may measure the amount of eccentricity based on an amount of change in the rotational speed of the drum after accelerating the drum.

As described above, the quantity is calculated by measuring the deceleration time when the controller 141 decelerates the drum 124. The longer the deceleration time of the drum 124, the higher the level of the quantity of the gun. According to an exemplary embodiment, the controller 141 may calculate an amount of fuel by measuring an acceleration time when accelerating the drum 124.

The amount of eccentricity is calculated based on the change amount of the drum speed after the controller 141 accelerates the drum 124. The speed of the drum 124 is calculated by using a Hall sensor or by measuring a current flowing through the motor of the driving unit 113. The controller 141 calculates the degree of eccentricity of the fabric by the difference between the speed change amount of the drum 124 and the reference speed change amount. The reference speed change depends on the quantity.

The controller 141 may accelerate or decelerate the drum 124 according to the amount of eccentricity. That is, the controller 141 may adjust the acceleration for accelerating or decelerating the drum 124 according to the amount of eccentricity.

8 is a flowchart illustrating a washing method according to an embodiment of the present invention.

The user inputs various washing conditions through the input unit 114a to start the operation of the washing machine 100. The user may set the washing stroke 210, the rinsing stroke 220, and the dehydrating stroke 230 to be continuously performed through the input unit 114a, and selects a desired stroke from among the washing stroke, the rinsing stroke, and the dehydrating stroke. It is also possible. Hereinafter, it will be described that the washing stroke 210, the rinsing stroke 220, and the dehydrating stroke 230 are all set by the user.

After the washing stroke 210 is performed (S10), the rinsing stroke is started (S20). As shown in FIG. 4, the washing stroke 210 may be sequentially performed with water supply 211, washing 212, podisic acid 213, drainage 214, and simple dehydration 215.

Water supply (221, 225) of the washing water for rinsing the cloth during the rinsing stroke 210 is made (S21), rinsing (222, 226) is performed by using the water supplied washing water, the drum 124 is rotated Podispersion 227 is performed (S23).

Since the overall configuration of the washing stroke 210 and the rinsing stroke 220 is the same as described with reference to Figure 4 will not be described.

In the washing method according to the exemplary embodiment of the present invention, whether the dehydration 231 is performed is determined based on the eccentricity U measured when the dispersion 227 of the rinsing stroke 220 is performed.

More specifically, the dispersion 227 of the rinsing stroke 220 is made in the state where the washing water is supplied into the drum 124, and at this time, it is determined whether the measured eccentricity U is within the allowable value Um (S24). ) Is entered into the dehydration 231 (S31). At this time, the allowable value (Um) may be set differently according to the quantity.

The main dehydration 231 is a process in which the drum 124 is accelerated to dewater the fabric, and the drum rotates at a speed higher than the embedding speed, which is a speed at which the carriage adheres to the inner wall of the drum 124 by centrifugal force. As described above, the rotation speed of the drum 124 may be 1000 rpm or more.

During the dehydration 231, the washing water dewatered from the cloth is drained out of the cabinet 111. The controller 141 controls the driving unit 113 to accelerate the drum 124 when the eccentricity U is within the allowable value Um, and controls the pump 136 to operate to perform the main dehydration 231. At this time, the controller 141 displays the dehydration icon on the progress display of the display unit 114a shown in FIG. 6 to indicate that the dehydration operation is started.

On the other hand, the display indicating the start of the dehydration operation is not limited to being output as an image through the display unit 114a, but may be output as sound through a buzzer or a speaker.

Since the dispersion 227 is made in the drum 124 in a state where the washing water is cold, the process of draining the washing water before the execution of conventional podis dispersion can be omitted, and if it is determined that the cloth in the drum is uniformly dispersed (U) <Um) By directly entering the main dewatering 231 is performed with dehydration and drainage, there is an effect that can reduce the overall required time of the dehydration stroke (230).

In the main dewatering 231, the pump 136 may be operated according to the water level in the tub 122, or may be repeatedly operated at regular intervals.

On the other hand, when the eccentricity U is larger than the allowable value Um, the pore dispersion 227 is repeated until the eccentricity U becomes smaller than the allowable value Um or a set number of times (S23).

As described above, the idea of the present invention in which dehydration is performed according to the amount of eccentricity (U) is not limited to entering the main dehydration 231 from the dispersing 227 of the rinsing stroke 220, the washing stroke 210 It can also be applied when entering the simple dewatering 215 in the podis dispersion 213, in this case, it is preferable that the drainage 214 is performed together when the simple dewatering.

Those skilled in the art will appreciate that the present invention can be embodied in other specific forms without changing the technical spirit or essential features of the present invention. Therefore, it should be understood that the embodiments described above are exemplary in all respects and not restrictive.
