- the input of the wash start command may be performed when the touch screen 122 is switched from the inactive state to the on state, the home screen is displayed on the touch screen 122, or a specific function icon is touched on the home screen . ≪ / RTI >
- it may be considered that an input of a wash start command occurs when a user is detected to be close to the washing machine 100 through a proximity sensor, or when it is paired with the smart server 200 or a user terminal. Or the closing of the door 120 is sensed after the laundry is introduced into the washing tub.
- the controller 180 of the washing machine 100 rotates the drum 150 in accordance with the rotation of the motor to detect the laundry load, that is, the load (S20). Then, the water supply amount is determined on the basis of the detected load, and the washing water is introduced into the washing tub.

- the average of individual pollution levels can be calculated.
- the camera provided in the washing machine 100 is activated to recognize the QR code (or bar code) of the laundry or laundry, so that the type and amount of the contamination can be estimated by grasping the type and the type of the laundry. For example, if it is classified as 'sportswear' or 'baby clothes', it can be estimated that the pollution degree is high.
- FIG. 5C shows an example in which a second graphic object 505 indicative of contamination (turbidity) sensing is output to the touch screen 122 during the course of the wash cycle.
- the information 504 indicating the washing time is outputted as shown in the left drawing of FIG. 5C while the contamination degree detection is not performed.
- a second graphic object 505 is displayed that includes an image indicating that it is on.
- the control unit 180 finally determines the amount of the laundry detergent to be introduced based on the detected size of the load and the contamination degree of the laundry (S40).
- the initial amount of the laundry detergent may be determined according to the load, and then an additional amount may be added to the initial amount of the laundry based on the degree of contamination of the laundry, or a predetermined amount may be removed from the initial amount of the laundry. For example, if the initial load is determined to be 40 ml as a result of load detection and the contamination level is judged to be very low, the final dosage may be changed to 30 ml, and 30 ml of laundry detergent may be automatically dispensed with the water supply.
- the amount of laundry detergent to be actually input may become larger or smaller than the initial amount of the laundry detergent determined only by the load of the laundry, or may be maintained without fluctuation. According to this, an optimal amount of laundry detergent can be automatically input depending on the state of the laundry.
- a graphic object associated with the input amount of the laundry detergent is displayed on the touch screen 122 of the washing machine 100 (S50).
- the graphic object may be text, an image, a moving image, and a combination of at least two of them.
- the graphic object may be displayed with a first object indicating the input amount of the laundry detergent.

Specifically, at the time when the input amount of the laundry detergent is determined, the first graphic object which can directly input the input amount is displayed. While the laundry detergent contained in the detergent supply unit 210 is being input into the washing machine, a second graphic object indicating the input of the laundry detergent associated with the first graphic object is displayed.
- a first graphic object 502 including a detergent cup image and text that can directly input the input amount is displayed on the touch screen 122 as shown in the left drawing .
- a second graphic object 503 including an animation image for putting detergent is output to the touch screen 122 as shown in the right side of FIG. 5B.
- a sound effect for example, a detergent input sound
- the second graphic object 203 may output an image that changes according to the degree of the laundry detergent contained in the detergent supply unit 210 being input to the washing tub, for example, the animation shown at the right side of FIG. 5B.
- the user may touch the image before the animation ends to input change commands such as interruption, addition, and reduction of the laundry detergent.

- the user can touch one of the items (pollution degree, time, detergent amount, rinsing frequency) displayed on the screen 506 to check related details or change the individual administration.
- a corresponding feedback voice or sound may be outputted together with the detection of the load of the laundry, the detection of the degree of contamination, the determination of the amount of laundry detergent, and the inputting process. Accordingly, even when the user is far away from the washing machine, the current operating state or the administrative course can be audibly confirmed.
- the amount of the laundry detergent which is automatically input according to the state of the laundry can be adjusted by itself without any user's operation, It automatically resets the course. Therefore, by using an amount of laundry detergent suited to the laundry, the use of the detergent can be prevented, and the efficiency of washing can be increased by appropriately resetting the individual administrative course according to the amount of detergent to be injected.
- Fig. 6 shows another exemplary flow chart of the washing machine operation
- Fig. 7D shows an example of a method of instantly changing the amount of laundry detergent determined.
- a step of receiving an input of a wash start command is performed (S601).
- the washing start command is issued when the touch screen 122 is switched from the inactive state to the on state or the home screen is displayed on the touch screen 122 Or when a user touches a specific function icon on the home screen or when a user is detected to be close to the washing machine 100 or is paired with a registered user terminal or when a closing of the door 120 is detected after the laundry is inserted And the like.
- the load of the next laundry is detected, and the amount of the primary detergent is determined on the basis of the load (S602). Then, the determined laundry detergent is introduced into the washing tub. Specifically, after the water supply to the washing tub is started, the gear pump is turned on / off so that the liquid laundry detergent corresponding to the first detergent input amount is introduced into the washing tub.
- the magnitude of the sensed load can be evaluated on a level by level basis.
- the level may be used as a criterion for setting the number of times of turbidity detection and the sensing interval of the laundry corresponding to the following process.
- the level of the load is determined as one of a plurality of levels divided into predetermined units according to the size of the load, and the value of the level of the load can be determined in proportion to the size of the load. For example, the larger the load, the higher the level, and conversely, the smaller the load, the lower the level.
- the control unit 180 or the detergent injection decision unit 182 determines the initial amount of laundry detergent determined based on the size or level of the load. While the water is being supplied to the washing tub, laundry detergent as much as the initial amount of injection is supplied to carry out the washing cycle.
- a step of detecting the contamination level of the laundry i.e. turbidity, is performed during the washing cycle (S603). That is, in this case, the degree of contamination of the laundry is measured after the laundry detergent is once charged according to the size of the load.
- the contamination level of the laundry can be detected more than once during the washing cycle.
- the detection result of the pollution degree can also be evaluated on a level basis according to a predetermined standard. For example, the first to third stages may be classified according to the degree of contamination of the laundry.
- the controller 180 may set the sensing frequency and the sensing interval of the pollution degree differently according to the size of the sensed load or the level of the estimated load. For example, if the level corresponding to the laundry load detected in step S602 is one of 1 to 3, the contamination degree detection may be performed only three times or less in total. On the other hand, if the level of the load detected in step S20 is one of 4 to 5, the contamination degree detection may be performed four to five times or more in total to obtain a more accurate detection result.
- control unit 180 may determine whether the second detergent is input based on the detected degree of pollution (turbidity) (S604).
- the control unit 180 can determine the additional amount of the laundry detergent to be input in the second order in consideration of the contamination level of the laundry and the size of the load. For example, if the degree of contamination of the laundry is detected in three stages and additional laundry detergent is determined, a larger additional load can be determined when the load level is large.
- the washing cycle is changed based on the laundry load, the degree of turbidity (turbidity), and the total amount of detergent, and a screen related to the changed washing cycle is displayed on the touch screen 122 (S605) .
- the change of the washing cycle means, for example, to increase the washing time, or to add, increase or decrease at least one of the rinsing cycle and / or the rinsing frequency of the dewatering cycle, and the dewatering strength. Also, maintaining the individual strokes, adjusting the water supply or adjusting the temperature of the water may be included in the change of the washing cycle.
- the screen related to the changed washing cycle refers to a washing process screen in which one or more individual strokes are changed according to the determination of load and contamination level of the laundry and the total detergent dosage.
- another image that can be visually distinguished from the unchanged individual stroke can be output to the information indicating the changed individual stroke.
- the other image may include a case where the size of the text is different, a different color is output, or other highlighting effect is output.
- the controller 180 can automatically adjust some individual strokes, for example, by increasing the number of times of rinsing, when the addition of laundry detergent is determined. Also, as a result of detecting the degree of contamination of the laundry, the controller 180 can adjust some individual strokes such as the number of times of rinsing and the increase of the dewatering strength, for example, even when no additional laundry detergent is required.
- the user can further control the amount of the detergent input automatically through the touch screen 122.
- An example related to this is shown in Fig. 7d.
- a touch input is applied to a particular image, e.g., a detergent cup image, of the graphic object 502 while the graphic object 502 representing the determined amount of laundry detergent is displayed on the touch screen 122
- the graphic object 502 is switched to a screen 502 'for controlling the amount of laundry detergent input.
- a first icon 714 for removing the amount of detergent to be input and a second icon 715 for adding detergent to be input may be displayed on the screen 502 '.
- the user can easily and quickly re-adjust the amount of detergent to be input by applying a touch input to the first icon 714 or the second icon 715. [ At this time, the amount of detergent to be relieved or added is cumulatively adjusted based on the degree or the number of touches of the touch input applied to the first icon 714 or the second icon 715.
- a screen showing the changed amount of the detergent may be output to the touch screen 122.
- the washing individual stroke is further automatically controlled. For example, the number of times of rinsing, the washing time may be increased, the temperature of water, the amount of water may be further changed. Accordingly, the detergent does not remain in the laundry even when the laundry detergent is further input by manual input, and when the amount of laundry detergent is reduced, electric energy, time, and the like can be saved.
- a predetermined image of the graphic object 503 for example a predetermined touch input (e.g., a long touch input)
- the addition of the detergent may be interrupted.
- the washing process is continued, unlike the case where the touch input is applied to the washing cut-off icon ("
- a detergent cup image showing 'amount of detergent added' to the amount of detergent to be injected may be displayed on the screen when a predetermined time has elapsed. This results in the same effect as that of removing the laundry detergent input.
- FIGS. 7A, 7B, and 7C are various illustrative conceptual diagrams related to a method of notifying the lack of laundry detergent in a washing machine according to an embodiment of the present invention.
- 8 is an exemplary flowchart for explaining another operation of the washing machine according to the embodiment of the present invention.
- FIG. 7A illustrates an example in which the amount of remaining laundry detergent contained in the storage container is sensed at the time when the start-of-laundry command is received, thereby notifying that the laundry detergent is insufficient to proceed with the washing.
- the controller 180 of the washing machine 100 may control the touch screen 122 to output information related to the remaining amount of the laundry detergent sensed by the remaining amount sensing unit, in response to the input of the wash start command.
- the selection of any one of the image 701a of the first washing tub 701a and the image 701b of the second washing tub 703 in the home screen 701 can be recognized as the input of the washing start command. Accordingly, the notification information 702 notifying the lack of the remaining amount of detergent contained in the storage container of the detergent supply unit 210, which is sensed by means of the remaining amount sensing unit, the air pocket, the electrode pair or the like, pops up on the touch screen 122 .
- the notification information 702 disappears when a touch is applied to an icon ('ok') requesting confirmation by the user or when a feedback voice (eg, 'OK') is recognized when the voice recognition function is activated. As a result, the notification information 702 disappears and the washing schedule setting screen 703, which is the next step, is output to the touch screen 122 as shown in FIG. 7B. At this time, an icon 711 indicating the remaining amount of the detergent amount may be displayed in one area of the washing-administration-setting screen 703, for example, at the upper part.
- a guide for filling the storage container of the detergent supply unit 210 with the laundry detergent or the liquid softening agent may be sequentially output to the touch screen 122.
- the user can easily charge the laundry detergent and the liquid softening agent according to the guidance information.
- the icon 711 disappears from the screen or is switched to another icon.
- the notification information 702 may disappear as the touch screen 122 is switched to the inactive state. In this case, the pop-up notification information 702 may be displayed again when the touch screen 122 is activated.
- FIG. 7C is an example of providing a notification that the laundry detergent is insufficient during the washing progress.
- the changed washing administration screen 704 is displayed on the touch screen, the remaining amount of detergent contained in the storage container of the detergent supply unit 210 can be detected. Detecting the amount of residual detergent can take several seconds.
- a pop-up message 702 indicating 'lack of detergent' may be displayed on the screen. Thereafter, when there is user feedback (e.g., touching the " ok " icon), the pop-up message 702 immediately disappears and the washing process is continued. Even after the pop-up message 702 disappears, a notification icon indicating the lack of detergent as shown in FIG. 7B may be continuously displayed on the upper part of the laundry administration screen 704.
- FIG. 8 is a flowchart for explaining the operation of the washing machine 100 according to the present invention when the amount of the laundry detergent contained in the storage container of the detergent supply unit 210 is insufficient after the amount of the laundry detergent is determined.
- the amount of laundry detergent to be input is determined based on the load and the degree of contamination of the laundry (S801), and then it is determined whether the amount of the laundry detergent contained in the storage container of the supplying unit 210 is less than the determined amount of the laundry detergent S802). Based on such judgment, whether or not the washing cycle is continued can be determined.
- means for detecting the remaining amount of the laundry detergent contained in the detergent supply unit 210 are provided. Specifically, the residual quantity sensing unit, the air pocket, the electrode pair, and the like may be in communication with the flow path of the detergent supply unit 210 so that the remaining amount of the laundry detergent can be accurately sensed without a false detection due to the detergent foam.
- step S802 if the remaining amount of detergent is sufficient (at least the determined amount of laundry detergent), the determined amount of detergent is input and the above-described graphic object is output to the touch screen 122 (S804).
- the predetermined alarm information is output (S803).
- the alarm information may be output in the form of a pop-up window on the touch screen 122. Alternatively, it may be output along with a predetermined sound or announcement voice (eg, 'lack of detergent').
- the controller 180 determines again whether the amount of detergent remaining in the storage container of the detergent supply unit 210 is less than the reference value (S805).
- the reference value may not be set based on the amount of the laundry detergent determined above, but may be a predetermined specific value. That is, the amount of laundry detergent may be slightly smaller or larger than the determined amount of laundry detergent.
- step S805 if the amount of the remaining detergent is greater than or equal to the reference value, the remaining amount of the detergent and the determined amount of the detergent detergent are determined as the amount of the detergent to be inputted into the washing machine.
- a detergent charging notification is output (S807).
- step S805 if it is determined in step S805 that the remaining amount of detergent is less than the determined amount of washing detergent and the reference value, the washing cycle can be stopped (S806). This is because, at this time, when the washing is continued only by the amount of the residual detergent, the contamination of laundry can not be removed.
