Hereinafter, the detailed structure of the door 120 will be described. Fig. 2 is an exploded perspective view of the door 120 shown in Figs. 1A to 1C.

2, the door 120 includes a door frame 130, a door window 136, a display module 128, and a door cover 190. As shown in FIG. As described above, the hinge unit 140 for coupling with the main body 110 is mounted on the door 120, but the hinge unit 140 is omitted in the figure.

In this embodiment, it is shown that the door 120 is formed in a circular shape (including a garden shape and an elliptical shape). However, the present invention is not limited thereto. The door 120 may be polygonal (square, hexagonal, etc.).

The door frame 130 is rotatably coupled to the main body 110 so that the hinge unit 140 is coupled to the door frame 130 and the main body 110, respectively.

As shown, the door frame 130 may include an outer frame 131 and an inner frame 132. The outer frame 131 and the inner frame 132 may be formed of a synthetic resin material (for example, an ABS material, a PC material, or the like).

The reason why the above-described configurations are referred to as the outer frame 131 and the inner frame 132 is that when the door frame 130 alone is placed in the closed state of the door 120, 110, and the inner frame 132 is directed toward the inside of the main body 110. As shown in Fig. Without this distinction, the outer frame 131 and the inner frame 132 may be referred to as a first frame and a second frame, respectively.

The door frame 130 includes a first opening 130a facing the garment input port 165 and a second opening 131b corresponding to the display module 128 mounted inside the door 120 in a closed state of the door 120 do. The first opening 130a may also be referred to as a door window hole in that the door window 136 is provided in the first opening 130a and that the display module 128 is mounted in the second opening 131b The second opening 131b may also be referred to as a display hole. The second opening 131b may be located on the first opening 130a.

The first opening 130a may include a front opening 131a formed in the outer frame 131 and a rear opening 132a formed in the inner frame 132. [ The second opening 131b is formed in the outer frame 131. A communication part 132b may be formed on the rear side opening 132a of the inner frame 132 and the display module 128 may be mounted inside the door frame 130 through the communication part 132b.

The door window 136 is installed in the door frame 130 to correspond to the first opening 130a. The door window 136 is formed of a translucent material such as glass or synthetic resin so that the door 120 is disposed to correspond to the garment input port 160a when the door 120 is closed.

A display module 128 is installed inside the door frame 130. The display module 128 is arranged to correspond to the second opening 131b and the touch screen 122 provided in the display module 128 is configured to output time information related to information processed in the washing machine 100. [

A door cover 190 is coupled to the door frame 130 to form an outer appearance of the door 120. The door cover 190 may be formed of a light-transmitting glass material or a synthetic resin material.

The door cover 190 has an opaque area 193 and a second translucent area 191 corresponding to the first opening 130a in the opaque area 193 and a second translucent area 191 corresponding to the second opening 131b, And a light-transmissive region 192. The first and second light- transmissive regions 191 and 192 are separated from each other by the opaque region 193. In this embodiment, the door frame 130 and the door cover 190 are formed in a circular shape so as to correspond to the circular door 120, and the first and second transparent regions 191, 192 are formed in a circular shape.

According to the present invention, the door cover is provided with an opaque region and first and second transparent regions that are separated from each other in the opaque region, and each of the first and second transparent regions has a window and a display So that a simple door appearance can be realized. Particularly, when the first and second light-transmissive regions are circularly formed so as to correspond to a circular door, the user can be provided with an integrated esthetics.

The door cover 190 may be formed to be bent at least in one portion. For example, the first cover portion and the second cover portion on both sides of the bending portion can be formed obliquely with respect to each other by the bent bending portion. Here, the first cover portion and the second cover portion are formed in a flat shape. In order to correspond to the door cover 190, the door frame 130 may also be formed at least partially bent.

In this embodiment, the first light-transmitting region 191 is formed over the first cover portion and the bending portion, and the second light-transmitting region 192 is formed in the second cover portion.

The second transparent region 192 is formed to be smaller than the second opening 131b so that the door cover 190 overlaps the second opening 131b when engaged with the door frame 130. [

As shown in the figure, the second opening 131b is formed in a rectangular shape corresponding to the rectangular display module 128, and the second transparent region 192 is formed in a circular shape to be overlapped within the second opening 131b . With the above configuration, the time information is output only to the portion corresponding to the circular second transparent region 192, so that the circular touch screen 122 can be provided to the user.

The circular display has a higher price than a generally used square display, and since it is difficult to accurately locate the mounting position, the assembly failure may occur frequently. However, according to the above structure, the user can be provided with the touch screen 122 which is seen as a circular shape, while using a square display which is less expensive and can be assembled in an accurate position.

Since the second transparent region 192 is surrounded by the non-transparent region 193, the time information output from the portion of the touch screen 122 that does not correspond to the second transparent region 192 is not visible to the user. In view of this, the time information may not be output to the portion of the touch screen 122 that does not correspond to the second light-transmissive region 192.

For example, in a state in which time information related to information processed by the washing machine 100 is output to a portion corresponding to the second transparent region 192 of the touch screen 122, An outer image surrounding the time information may be output. The outline image may be filled with a specific sequence of colors (for example, black) as a portion that does not correspond to the second transmissive region 192.

For example, in a state in which time information related to information processed by the washing machine 100 is output to a portion of the touch screen 122 corresponding to the second transparent region 192, May be configured to be off. That is, not only the time information but also the outline image is not output to the portion of the display module 128 which does not correspond to the second transparent region 192. In this example, since only a part of the touch screen 122 is driven, the touch screen 122 can be efficiently driven as compared with the previous example in which the entire touch screen 122 is driven, thereby achieving a power saving effect.

The touch screen 122 formed on the door cover 190 may have a mutual layer structure with a touch sensor (not shown) or may be integrally formed to implement the touch screen 122. The touch screen 122 functions as a user input for providing an input interface between the washing machine 100 and the user and can provide an output interface between the washing machine 100 and the user. For example, the selection and change of the operation mode for performing the washing, the dewatering drying, and the like can be implemented by the touch input (or touch) of the user on the touch screen 122.

The touch screen 122 is provided with a touch sensor for sensing a touch input.

The touch sensor senses a touch input applied to the touch screen 122 using at least one of various touch methods such as a resistance film type, a capacitive type, an infrared type, an ultrasonic type, and a magnetic field type.

As an example, the touch sensor may be configured to convert a change in a pressure applied to a specific portion of the touch screen 122 or a capacitance occurring at a specific portion into an electrical input signal. The touch sensor may be configured to detect a position, an area, a pressure at the time of touch, etc. of a touch target object touching the touch screen 122 on the touch screen 122. Here, the touch object may be a finger, a touch pen, a stylus pen, a pointer, or the like as an object to which a touch is applied to the touch screen 122.

As such, when there is a touch input to the touch screen 122, the corresponding signal (s) is sent to the controller. The controller processes the signal (s) and sends the corresponding data to the controller 180 (FIG. 3). Thus, the control unit 180 can know which area of the touch screen 122 is touched or the like. Here, the controller 180 may be a separate structure from the controller 180, or the controller 180 itself.

Meanwhile, the control unit 180 may perform different controls or perform the same control according to the type of the touch object touching the touch screen 122. Whether to perform different controls or perform the same control depending on the type of the touch object may be determined according to the operating state of the washing machine 100 or an application program being executed.

The touch screen 122 may be a short touch, a long touch, a multi touch, a drag touch, a flick touch, a pinch-in touch such as a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch, and the like.

The touch screen 122 is configured to sense a touch input to a sensing region including the second transmissive region 192. [

The touch screen 122 is attached on the rear surface of the door cover 190 so as to cover a part of the opaque region 193 surrounding the second transparent region 192 and the second transparent region 192 . The touch sensing area of the touch screen 122 includes not only the second transmissive area 192 but also a part of the opaque area 193 surrounding the second transmissive area 192. Accordingly, various UIs or GUIs using a part of the opaque region 193 surrounding the second transparent region 192 can be provided.

In this structure, the touch sensor is formed in the form of a touch film having a touch pattern, and may be disposed between the door cover 190 and the display module 128. The touch film is made of a transparent conductive film, and the known ITO film (Indium-Tin Oxide film) or CNT film (Carbon Nano Tube film) can be used as the touch film.

The touch film may be composed of one or two layers. For example, in the case of a glass-film-film (GFF) in which the touch film is composed of two layers, the touch film may be attached to the rear surface of the door cover 190 or attached on the display module 128 . As another example, in the case of a method [G1F (Glass-Film)] in which the touch film is composed of one layer, the touch film may be attached to the rear surface of the door cover 190 and formed integrally with the door cover 190 .

The touch sensor may be formed by patterning metal wires directly on the rear surface of the door cover 190 without a separate touch film.

Alternatively, the touch sensor may be formed integrally with a display provided in the display module 128. For example, the touch sensor may be on-cell on a display or in-cell on a display.

The present invention can be applied not only to the case where the touch screen 122 is provided on the door 120 but also when the touch screen 122 is disposed on a position other than the door 120. For example, the touch screen 122 may be provided on one surface of the main body 110, and the one surface may correspond to a surface on which the power button 170 is disposed on the main body 110. However, for convenience of explanation, the case where the touch screen 122 is provided on the door 120 is described as an example, but the present invention is not limited thereto.

For example, the washing machine 100 may request transmission of weather information to the server 200 connected via Wi-Fi, and the server 200 may transmit updated weather information to the washing machine 100 in response thereto .

Here, the server 200 may be a smart server that collects big data including weather information, or may be an electronic device capable of providing weather information, for example, a user terminal. In addition, the user terminal may include, for example, a smart phone, a tablet, a notebook, an ultrabook, a wearable device, a watch type terminal, and the like.

The communication unit 155 may be a communication unit such as a Bluetooth ™, a Radio Frequency Identification (RFID), an Infrared Data Association (IrDA), a UWB (Ultra Wideband), a ZigBee, -Fidelity), Wi-Fi Direct, and Wireless USB (Wireless Universal Serial Bus) technology. For example, the washing machine 100 and the user terminal can perform wireless data communication using Bluetooth communication in response to the user terminal registered in the main body of the washing machine 100 being close to each other.

The control unit 180 controls the overall operation related to the driving of the washing machine 100. Further, it is possible to control the operation of each constitution provided in the washing machine 100, and to process signals generated therefrom.

Here, the event related to the laundry may mean setting / changing of individual administration such as connection with an external device, power on / off, setting of a washing course, rinsing, dewatering and drying, initiation of washing, .

The sensor unit 145 may include at least one sensor for sensing at least one of information in the washing machine 100, surrounding environment information surrounding the washing machine 100, and user information. For example, the sensor unit 145 may include a sensor configured to sense opening and closing of the door 120, and the sensor may be disposed on one side of the door 120 or the hinge unit 140. In addition, the sensor unit 145 may sense a user approaching the washing machine 100 through a proximity sensor.

The memory 195 may store information related to programs and operations related to washing. The memory 195 may be a flash memory type, a hard disk type, a solid state disk type, an SDD type (Silicon Disk Drive type), a multimedia card micro type (RAM), a static random access memory (SRAM), a read-only memory (ROM), an EEPROM , electrically erasable programmable read-only memory (PROM), programmable read-only memory (PROM), magnetic memory, magnetic disk, and optical disk.

The washing machine 100 according to the present invention may be connected to a server that provides weather information through wireless communication, which may be referred to as a 'smart server' hereinafter. Upon receipt of the input of the start-of-laundry command, the server 200 may request that the updated weather information be transmitted.

When the updated weather information is received, the washing machine 100 according to the present invention judges the degree of laundering fitness based on the information, and based on the determined laundromat suitability, the received weather information, and the laundry pattern of the user stored in the memory 195 The optimum washing course can be set. Then, on the touch screen 122, an option screen for executing the washing with the optimum washing course set as described above is displayed. Then, the user can perform the washing with the optimum washing course simply by touching the option screen without inputting the respective strokes of the washing course (for example, rinsing, dehydrating, drying, etc.). In addition, since the optimum washing course takes into consideration not only the current weather condition but also the user's individual taste, the user's satisfaction with use can be further improved.

4 is a flowchart illustrating the operation of the washing machine according to an embodiment of the present invention.

Referring to FIG. 4, a step in which the washing machine 100 according to the present invention receives input of a wash start command is started (S10).

Herein, the input of the wash start command is an intentional input for starting laundry, for example, it may mean that a push input is applied to the power button 170 of the washing machine 100. [ Alternatively, 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 > Alternatively, 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.

When the washing start command is input, the washing machine 100 may request the connected server to update the weather information (S20). Here, the weather information may include data such as temperature, wind speed, humidity, precipitation, solar radiation, fine dust, and ozone.

In addition, the request for weather information can be transmitted to the server 200 at predetermined time intervals, and the latest weather information can be received from the server 200 in the washing machine 100 at that time. In addition, the washing machine 100 and the server 200 may be wirelessly connected to each other at the time when a wash start command is first inputted. In this case, a notification sound indicating that the wireless connection is established may be output through the sound output unit 125. [

Next, the controller 180 of the washing machine 100 performs a step of calculating a wash index indicative of the degree of washing fitness based on the updated weather information (S30). Here, 'laundry index' means exponentiation of how well the laundry will be dried in consideration of weather conditions, such as solar radiation, wind speed, temperature, and humidity. It is also named as 'laundry index'. In general, when the wash index is 80 or more, it is 'very good (most suitable)', when the wash index is in the range of 60 to 79, 'good' Is less than 30, it can be said to be 'bad (inappropriate)'.

On the other hand, if the laundry index is provided together with updated weather information in the 'smart server', the step of calculating the wash index (S30) may be omitted. In such a case, it suffices to perform only the operation related to displaying the received wash index on the screen.

Then, the control unit 180 of the washing machine 100 sets the washing course based on the calculated washing index, updated weather information, and the washing pattern of the user (S40). Here, the laundry pattern of the user can be analyzed based on the laundry history information for the predetermined previous period or read out from the memory 195.

Here, the laundry pattern may be generated on the basis of information on the laundry course performed for each season, month, and day based on the laundry history information.

In one example, the user's laundry pattern may be updated at a predetermined period or at a specific event occurrence. In addition, the cycle of the update may be changed according to the number of washing machines and the interval. Further, in another example, the plurality of users may be stored to have different washing patterns. In this case, a process of recognizing the user through voice recognition or the like may be performed prior to the input of the laundry start command, and the laundry pattern corresponding to the recognized user may be read from the memory 195.

The washing course includes at least one of the strength, the time, and the number of times of each of the individual strokes such as the washing stroke, the rinsing stroke, the dewatering stroke, and the drying stroke, and information about the water temperature. The laundry course set according to the embodiment of the present invention means an optimal laundry course that satisfies both the current weather condition and the user's usual laundry pattern, and may be hereinafter referred to as a " smart laundry course ".

Since the weather conditions and the user's laundry pattern vary with the passage of time, the intensity, time, and number of individual strokes of the smart laundry course can be changed each time.

Specifically, the smart laundry course has a very large number of cases depending on the combination of updated weather information, user's laundry pattern, and laundry index. For example, although the washing index is the same, the washing course may be set differently according to the washing pattern of the user (for example, the 'strongest' pattern of dehydration). Further, even if the washing index and the washing pattern are the same, the rinsing cycle may be added one or two more times in the existing washing pattern if the fine dust amount is high.

Next, an option screen for executing the laundry with the smart laundry course set as described above is displayed on the touch screen 122 (S50). The user confirms the individual strokes of the laundries set through the option screen, and then selects the laundering drive button included in the option screen to perform laundering with the optimum laundering course set.

FIG. 5 is a conceptual diagram illustrating the operation of FIG. 4 in detail. 5, when the touch screen 122 provided in the washing machine 100 is activated, a home screen 501 including a graphic object corresponding to a washing related function that can be executed by the washing machine is displayed on the touch screen 122 . Here, the graphic object may include an icon, a menu, an item, a guidance message, and the like.

For example, the home screen 501 may display a plurality of icons for executing predetermined washing-related functions. Here, the plurality of icons may mean menus for executing different washing methods depending on the washing time, the type of laundry, and the like. For example, a plurality of icons, such as standard wash, speed wash, synthetic fiber, blend wash, knit / wool, smart care 510, may be displayed along the circumference of the circular touch screen.

There is no particular limitation on the manner of arranging the plurality of icons. Although not shown, the plurality of icons may be arranged in columns / rows when implemented with a rectangular touch screen. Alternatively, if a specific icon is selected on the home screen, sub-icons corresponding thereto may be displayed, or a single search window may be displayed instead of a plurality of icons to search a desired function.

An indicator area 520 indicating a wireless connection with the server 200 is displayed in one area of the home screen 501, for example, at the top. The user can visually recognize the connection / disconnection between the washing machine 100 and the server 200 through the indicator area 520.

Meanwhile, although not shown, in one example, when the connection between the washing machine 100 and the server 200 is disconnected through the indicator area 520, a registered user terminal (not shown) is brought close to the indicator area 520 So that the pairing of the registered user terminal and the washing machine 100 can be performed. In this case, the washing machine 100 can receive weather information from the registered user terminal through the short distance communication.

While the home screen 501 is being displayed, if the user touches or touches the smart care 510 using the touch object, for example, the user's finger, the smart care 510 is selected, Lt; / RTI > In other words, here, it is recognized that a command to start the laundry is input at the time when the touch is applied to the smart care 510.

As the touch input is applied to the smart care 510, the washing machine 100 receives the updated weather information through the wireless communication with the server 200, for example, Wi-Fi communication. At the same time, the controller 180 reads the laundry pattern information based on the history of the washing operation information of the washing machine 100 from the memory 195 and reads the laundry pattern information. Also, the controller 180 may calculate the wash index indicating the degree of the wash suitability based on the received weather information, or may receive the wash index calculated by the server 200 together with the weather information.

Then, the controller 180 adjusts the detailed strokes included in the laundry pattern information read based on the weather information and the wash index to set a smart laundry course.

For example, one or more of the intensity, time, and frequency of the dewatering cycle in the user's normal laundry pattern can be adjusted on the basis of weather information such as humidity, rainfall / solar radiation, wind speed, and washing index indicating the degree of washing. Further, in the case where the amount of fine dust is large, the number of rinsing strokes can be added one more time in the user's usual laundry pattern. As described above, since the adjustment of the detailed stroke suitable for the weather and the washing index is performed based on the usual laundry pattern of the user, even if the fine dust amount is the same, the user can set the rinsing frequency twice or three times The number of rinsing times may vary.

For example, while the washing machine 100 collects and analyzes the updated weather information and the user's laundry pattern, the image information 502 such as a predetermined image, text, moving image, and animation may be output to the touch screen 122 .

When weather information collection fails due to the disconnection with the server 200 while the image information 502 is being output, this state can be notified via the image information 502. [ At this time, if the user terminal is brought close to the indicator area 520, weather information can be received from the paired user terminal and the corresponding operation can be continuously performed without interruption. On the other hand, even when the disconnection state between the server 200 and the user terminal continues, a smart laundry course may be set based on only the user's laundry pattern without interruption.

The smart laundry course information thus set is output to the touch screen 122. As shown in FIG. 5, a first graphical object for indicating detailed administration information of the set laundry course and a second graphic object 511 corresponding to the calculated wash index are displayed on the option screen 502. [

Here, the first graphical object may be a graphical object in which the individual administrative information of smart laundry course information is displayed in a clockwise or semi-circular manner according to the flow of the washing sequence in the form of text such as, for example, three times of rinsing, strong dehydration, Can be displayed in a clockwise direction.

Also, the second graphic object may be displayed as an image in which the user can intuitively understand the wash index. The second graphic object may be displayed as different images depending on the fitness level of the calculated wash index. Here, different images mean different shapes, colors, highlighting effects, facial expressions / shapes of emoticons.

For example, the second graphic object may be formed to have different colors depending on the fitness level of the wash index. For example, the higher the fitness level of the wash index is, the more the blue color is applied to the wash index icon, and the lower the fidelity level of the wash index is, the more red color can be applied to the wash index icon. For example, if the wash index is above 80 (very good or best), it is blue. If the wash index is in the range of 60 to 79 (good or good), it is green (green) (Red) if the wash index is less than 30 (bad or inadequate).

Referring to FIG. 5, a color representing the fitness level of the washing index may be displayed along the rim of the circular image in which the 'wash index' text is displayed. The user can visually intuitively determine whether the wash index is high or low through the graphic object on the option screen. This provides intuitive help in determining whether the user is performing laundry and whether to further manipulate the individual administration.

In addition, the option screen 502 is provided with an execution button 512 for executing the laundry with the smart laundry course corresponding to the first graphic object. When the user touches the execution button 512, the washing operation is immediately started by the smart washing course.

On the other hand, if the user touches the execution button 512 to start the washing operation again, the washing operation is stopped and the detailed strokes of the smart laundry course corresponding to the first graphic object can be displayed again. Accordingly, even after the washing is started, the washing course can be changed by touching the displayed detailed strokes. A total washing time is displayed at the center of the option screen 502, and a counting operation is performed when the washing operation is performed.

In the option screen 503, a third graphic object may be displayed in the detailed stroke adjusted in relation to the laundry pattern among the detailed strokes of the laundry pattern information. 5, if the conventional washing pattern is a 'rinse twice' and a 'middle dehydration', if a smart laundry course is set by addition of one rinse and strong dehydration based on the wash index and weather information, The square frame images 511a and 511b can be displayed in the highlight area, and the 'rinse three times' display area can be displayed with the highlighting effect, respectively.

In one example, a guidance voice informing the changed administration information may be output through the sound output unit 125. [ For example, at the time of outputting the option screen 503, voice information 'perform washing with three times of rinsing and strong dehydration' together with 'smart laundry course is set' can be outputted through the sound output unit 125 have. In the case where a microphone (not shown) is provided in the washing machine 100, it is also possible to input a washing start or a rinse or dehydrate reset command through the user's voice in response to the voice information.

As described above, according to the embodiment of the present invention, only when the user inputs the wash start command, the current weather information and the usage pattern are collected and analyzed to set an optimal washing course. Therefore, the user does not have to add or change the individual administrations according to the current weather conditions. Also, since the optimum washing course is based on the analysis of the laundry pattern of the existing user, the user's taste can be satisfied at the same time. Furthermore, by providing visual information that allows the user to intuitively understand the wash index, it helps the user to decide whether to proceed with washing and whether to change the administration by himself or herself.

Hereinafter, various operations related to directly confirming the washing index and weather information on the touch screen 122 of the washing machine 100 will be described in detail. 6A, 6B, and 6C show examples of various screen changes related to providing the wash index information.

6A, the touch screen 122 of the washing machine 100 displays an option screen 603 for executing a smart washing course set based on the washing index, weather information, and the user's washing pattern.

A wash index icon 611 displaying the text 'Wash Index' is displayed in one area of the option screen 603, for example, the center of the option screen 603, and the wash index icon 611 has a fidelity level (very good, (For example, best-to-blue) corresponding to the color (e.g., good, medium, or poor) may be displayed.

6A, when a tab or a single touch is applied to the wash index icon 611, the option screen 603 displays the weather information and the index of the wash index Screen information 604 is displayed.

The converted screen information 604 displays detailed information related to the weather (for example, temperature, humidity, fine dust, precipitation probability, etc.) along with index information (e.g., 85) of the wash index as shown in FIG. 6A. A color corresponding to the fitness level ('very good') of the washing index can be displayed on the outer circumferential edge of the screen information 604. Thus, the user can directly check the updated weather information and the index information of the wash index through the touch screen 122 provided in the washing machine 100.

While the screen information 604 is being displayed, the washing machine 100 may continuously request updated weather information to the server 200 at a predetermined time interval (e.g., 10 seconds). That is, even if there is no separate update input, the latest weather information and wash index can be confirmed on the screen.

In one example, the screen information 604 may be output in the form of a pop-up window. In this case, the screen information 604 is popped up on the upper part of the option screen 603 only when a touch is applied to the wash index icon 611. When the touch is released, the screen information 604 is immediately removed . The screen information 604 is touched by the OK button 614 or is switched to the option screen 603 after a predetermined time elapses.

On the other hand, the information on the wash index may be provided only as an image, not as a specific index. For example, FIG. 6B shows a face image 605 (smiley face) in a case of a high degree of laundry fit, and FIG. 6B shows a face image 606 Expression). According to this, a user with a poor visual acuity can easily recognize the wash suitability through the expression of the face image provided on the touch screen 122.

6C, a first indicator 615 for confirming the wash index history is provided at the top of the first screen information 605 indicating the index information of the wash index, for example, An arrow image can be displayed.

The user can touch the first indicator 615 to check exponential information of the last wash index and past weather information (not shown). To this end, the memory 195 of the washing machine 100 may accumulate and store exponential information of the laundry index, weather information, and information related to the smart laundry course generated based thereon for a predetermined period of time. Cumulative information is removed in the oldest order when new weather information is received.

The user can return to the past time point and check the wash index and weather information (not shown) as much as the number of touches or the touch time applied to the first indicator 615. For example, when the first indicator 615 is touched once, it can be switched to the second screen information 606 indicating the exponential information (e.g., 'good', 65 ') of the yin wash index as shown in FIG. 6C . At this time, a first indicator 616 for returning to the first screen information 605, for example, a right arrow image, is displayed on the upper right side of the second screen information 606.

At this time, if the laundry is repeated several times a day, the laundry index may be calculated several times, so that only the laundry index and weather information (not shown) calculated when the last or first washing operation is performed can be provided. Alternatively, it may be provided in the form of a mean value of a plurality of laundering indices and weather information. It should be noted that the difference from the currently set Smart Laundry Course is based on the fact that the Smart Laundry Course in the past was actually executed.

Further, in one example, the detailed strokes of the smart laundry course that has been executed in the past can be immediately confirmed and executed at the present time. Specifically, if a touch is applied to the area where the exponent information is displayed, for example, the central area, in the second screen information 606 indicating exponential information of the yin-washing index in FIG. 6C, Exponential information appears along the periphery of the displayed area, i.e., the outer circumferential surface of the touch screen 122. [ For the sake of convenience of explanation, the screen thus changed will be referred to as the third screen information 607. The user can visually confirm the detailed process of the smart laundry course executed yesterday through the third screen information 607. [

At this time, the controller 180 of the washing machine 100 determines whether the currently set smart laundry course (hereinafter referred to as the 'first smart laundry course') and the smart laundry course (hereinafter referred to as the 'second smart laundry course' The highlighting effect can be output to the individual administrative information (e.g., 'rinse 5 times') that is different from the first smart laundry course (617a).

When the user touches the execution button 512 displayed on the third screen information 607, the second smart laundry course is executed. Alternatively, the user may touch the back button 621 in the third screen information 607 to execute the first smart laundry course. Alternatively, the user may touch the individual stroke displayed on the third screen information 607 to perform the washing with the changed second smart washing course.

Next, FIGS. 9A, 9B, and 9C show various examples associated with the time point at which the wash index information is provided.

First, FIG. 9A is an example related to providing wash index information on the home screen of the touch screen 122. FIG. When the touch screen 122 of the washing machine 100 is activated, a plurality of icons corresponding to laundry-related functions that can be executed by the washing machine are displayed on the home screen 901.

When a specific icon among a plurality of icons, for example, SmartCare 910, is first touched, the controller 180 recognizes that the input of the wash start command has been received. Thereby, the above-described updated weather information request and calculation of the wash index are performed.

The control unit 180 displays exponential information of the laundry index calculated on the basis of the updated weather information or received from the server 200 on the touch screen 122 while the smart care unit 910 is touched, Can be output. For example, as shown in FIG. 9A, a region other than the smart care 910 may be inactivated, and a speech bubble message 912 informing the wash index '80' may pop up.

The speech balloon message 912 is displayed only when a touch is applied to the smart care 910, and disappears when the touch is released. In this case, the execution screen corresponding to the smart care 910, that is, the above-described option screen, may be executed, for example, when a touch applied to the smart care 910 is dragged toward the center of the home screen 901. [

In another example, FIG. 9B shows an example in which exponential information of the washing index is continuously displayed in a predetermined area while the touch screen 122 of the washing machine is in an activated state. At this time, the activation state includes not only the entire on state of the touch screen 122 but also a specific region, for example, only the upper indicator region 920a is on as shown in FIG. 9B . In the indicator area 920a, the index information 912b of the wash index can be displayed at any time along with an icon indicating the connection status with the server 200. [ When the touch information is added to the index information 912b of the wash index in the indicator area 920a, details of the weather information can be confirmed.

9C shows index information of the wash index when the door is closed after the washing machine 100 is loaded with laundry. The laundry index has a high probability that useful information will be used at the time of starting the laundry, and the time for starting washing is generally performed within a predetermined time after the laundry is supplied and the door is closed. In the case of FIG. 9A, the power consumption is increased in that it requires a simple input of the user, in the case of FIG. 9B, at least a part of the touch screen must be kept active.

9C, when the door 120 is opened, the touch screen 122 remains in an inactive state (900). If the closing of the door 120 is detected after the laundry is inserted into the washing tub, it is recognized that the input of the washing start command has been received. Accordingly, the server 200 requests the updated weather information through the communication unit 155 of the washing machine 100. For this purpose, a sensor for sensing the opening and closing of the washing machine door 120 may be provided on one side of the door 120 or on the hinge part 140. Thereafter, the index information of the wash index is provided to the touch screen 122 even if the user does not push or touch the power button 170 or the touch screen 122 (940).

Accordingly, it is not necessary to perform additional input on the home screen as shown in FIG. 9A or to keep a part of the touch screen continuously activated as shown in FIG. 9B in order to check the washing index.

The control unit 180 determines whether the washing index of the washing index displayed on the touch screen 122 is lower than the threshold level or not, Too low ') can be output. Thereby helping the user to determine whether to postpile the laundry later or add a drying stroke.

Hereinafter, FIG. 7 is an exemplary flowchart illustrating another operation of the washing machine according to the embodiment of the present invention.

Referring to FIG. 7, when the laundry is completed with the smart laundry course or the modified laundry course (S710), the washing machine 100 may request the connected server 200 to update the weather information again (S720).

Then, the controller 180 of the washing machine 100 calculates the wash index indicating the washout fitness based on the updated weather information (S730). The reason why the wash index is once again calculated after the completion of the washing is that the weather condition may be changed from the time when the washing is started when the washing time is long. In addition, since the time at which the laundry is actually dried is closer to that at the time when the laundry is completed than at the time when the laundry is started, the availability of the laundry index can be further improved.

When the wash index is recalculated as described above, the controller 180 of the washing machine 100 sets the drying stroke course based on the calculated wash index (S740).

At this time, a process of comparing and analyzing the first wash index calculated at the time when the input of the wash start command is received and the second wash index calculated after completion of washing may be further performed. Then, one of the strength, time, and frequency of the drying stroke may be set to correspond to the comparison and analysis result. In order to distinguish the drying stroke course set on the basis of the wash index from the case of the user input, hereinafter, it can be named as the 'smart drying stroke course'.

On the other hand, if the drying cycle has already been added to the smart laundry course, the controller 180 controls the intensity, time, and frequency of the drying cycle of the smart laundry course according to the comparison and analysis result of the first washing index and the second washing index A smart drying administrative course can be set by appropriately adjusting one or more. For example, if the second laundering index is higher than the first laundering index, a smart drying stroke course can be set by decreasing the drying stroke time. On the other hand, if the second laundering index is lower than the first laundering index, the smart drying stroke course can be set by increasing or increasing the time of the drying stroke course.

Next, the smart drying and drying course information may be output to the touch screen 122 in response to the opening signal of the door 120 of the washing machine 100 (S750). To this end, as described above, a sensor for detecting the opening and closing of the door 120 may be provided on one side of the door 120 or on the hinge part 140.

Specifically, when the opening of the door 120 is detected after the completion of washing, the touch screen 122 is activated and a drying option screen for executing the smart drying stroke is displayed on the touch screen 122. Thereafter, if the user touches the execution button of the drying option screen, the drying is immediately executed in the drying cycle optimal for the current weather condition. The reason why the drying option screen is provided in response to the opening signal of the door 120 after the completion of the washing is to provide useful information in consideration of the case where the laundry is collected after a long time after the washing is completed.

FIG. 8 shows a specific screen change according to the operation of FIG. When the laundry is completed with the set or changed smart laundry course, the touch screen 122 displays screen information 801 indicating that the laundry is completed. In the indicator area 820 of the screen information 801, an icon indicating connection / disconnection with the server 200 is displayed.

The control unit 180 requests updated weather information from the connected server 200, and re-calculates the wash index based on the received weather information. Thus, during the collection of the weather information and the calculation of the washing index, the predetermined idle screen 802 is output to the touch screen 122. [

The control unit 180 requests updated weather information to the server 200 at a reference time interval until the opening of the door is detected after the completion of the washing, and re-calculates the washing index. However, the idle screen 802 may be output only for a predetermined time after the completion of washing in consideration of power consumption, and thereafter, the touch screen 122 may be inactivated.

The control unit 180 can set the drying stroke course based on the latest weather information and the re-calculated wash index. For example, when the washing is started, the humidity is low. However, when the humidity is high or the humidity after the washing is high, it is possible to increase at least one of the strength, the number of times, and the time of the drying stroke. Meanwhile, in one example, the smart drying stroke can be set based on the washing pattern of the user in addition to the washing index and weather information. For example, when the user performs a drying stroke for 30 minutes after the completion of the normal washing, the drying stroke time can be set to one hour when the washing index is low.

When the opening of the door 120 is sensed, a drying option screen 803 is displayed which enables the smart drying stroke to be immediately executed while the touch screen 122 is activated. A graphical object 811 representing the wash index is displayed at the center of the drying option screen 803, and the set drying time is displayed in the inside area 802. When the user selects the execution button 812 after confirming the closing of the door 120, drying is performed in the set smart drying stroke.

10 is an exemplary flowchart illustrating another operation of the washing machine according to the embodiment of the present invention. And shows a concrete example of the operation method of the washing machine when the set smart administration course is changed through the touch screen.

In response to the input of the laundry start command, an option screen for executing the laundry with the smart laundry course set on the basis of the laundry index, the weather information, and the laundry pattern of the user is displayed on the touch screen 122 provided in the washing machine 100 (S50).

The washing machine 100 may sense that an input for adjusting at least one individual stroke, i.e., a touch input, is received in the displayed option screen (S60).

To this end, the detailed screen information of the set smart laundry course is displayed on the option screen. Then, the user can arbitrarily adjust the intensity, time, and frequency of individual strokes such as a rinse stroke, a dehydration stroke, a water temperature, a drying stroke, and the like using the touch input. That is, it is possible to quickly perform the adjustment of the individual strokes on the option screen without changing the screen.

Next, the controller 180 of the washing machine 100 may perform updating of the user's washing pattern based on the received input (S70). Specifically, when the washing operation is performed with the changed washing course, the controller 180 can learn the user's washing pattern based on the changed washing course. And can be used to calculate the next wash index based on the updated wash pattern.

In addition, the control unit 180 may store the changed washing course as the optimal washing course corresponding to the corresponding washing index. However, even if the wash index is the same, the smart laundry course can be set by correspondingly adjusting the individual strokes of the stored optimal wash course when specific weather information is different (for example, fine dust level, insufficient solar radiation, etc.).

As described above, according to the washing machine and the washing method of the present invention, when only the washing start command is inputted, the current weather information and the usage pattern are collected and analyzed to set an optimal washing course. Therefore, the user does not have to add or change the individual strokes of the laundry course according to the current weather conditions. Also, since the optimum washing course is based on the analysis of the laundry pattern of the existing user, the user's taste can be satisfied at the same time. In addition, it provides visual information that allows the user to intuitively understand the wash index, thereby helping the user decide whether to proceed with washing and whether to change the administration. Further, it is possible to easily and quickly change a desired individual stroke by a convenient touch operation even after an optimum washing course is set. In addition, after the completion of the washing, the screen is provided so as to perform the optimum drying process based on the latest weather information, thereby achieving convenient and reliable washing of the interface.

The present invention described above can be embodied as computer-readable codes on a medium on which a program is recorded. The computer readable medium includes all kinds of recording devices in which data that can be read by a computer system is stored. Examples of the computer readable medium include a hard disk drive (HDD), a solid state disk (SSD), a silicon disk drive (SDD), a ROM, a RAM, a CD-ROM, a magnetic tape, a floppy disk, , And may also be implemented in the form of a carrier wave (e.g., transmission over the Internet). Also, the computer may include a control unit 180 of the terminal. Accordingly, the above description should not be construed in a limiting sense in all respects and should be considered illustrative. The scope of the present invention should be determined by rational interpretation of the appended claims, and all changes within the scope of equivalents of the present invention are included in the scope of the present invention.
