By the way, the conventional washing machines are provided with a control panel for the course selection unit for the course selection, a control unit for modifying the various course information for the course, and a display unit for displaying a variety of information while the washing machine is running do. As such, when the course selection unit, the operation unit, and the display unit are separately provided, a lot of time and cost may be required to assemble the control panel. Furthermore, a large number of buttons and lamps included in the course selection unit, the operation unit, and the display unit are disposed on the control panel, so that it is not easy for the user to drive the washing machine through proper operation. Therefore, various embodiments of the present application to simplify the configuration of the control panel to be suitable for the user while at the same time look at a washing machine having a configuration that allows easy operation and various information display of the washing machine.

The control panel 30 of the washing apparatus 10 according to an embodiment may include a driving and pause button 50 for starting the operation of the display 40 and the washing apparatus. The display 40 is provided in the control panel 30 and may be provided as a touch screen type that allows the user to recognize various information and at the same time allows the user to select a washing course. Accordingly, the user may operate the display 40 to select a washing course of the washing apparatus 10 or to modify various course information, additional information or driving information about washing. In addition, the display 40 may display the information on the washing apparatus 10 or the information on the washing course while the washing apparatus is driven so that the user may recognize it. On the other hand, when the user selects the washing course can operate or stop the driving of the washing machine by operating the drive and pause button 50. In this case, the washing apparatus 10 is driven according to the selected washing course.

Therefore, the washing apparatus 10 according to an embodiment includes a display 40 on the control panel 30, and the display 40 enables the washing machine to operate, modify information, and display information. However, even when the display is provided as described above, the washing machine may be easily operated by the user according to the change and / or arrangement of the screen implemented in the display, and may be difficult for the user to operate. Hereinafter, with reference to the drawings will be described with respect to the switching and / or arrangement of the screen of the display so that the user can easily operate the washing machine and at the same time easily recognize a variety of information about the washing machine.

2 and 3 are front views showing only the display 40 in FIG. 1 in an enlarged manner.

As described above, the display 40 provides various information to the user, and enables the user to make various selections necessary for driving the washing apparatus based on the provided information. In addition, the user may store various washing information, additional information, driving information, etc., including the course selected by the user, so that the stored information may be used when the washing apparatus is driven again later. In addition, energy information provided by the utility company may provide information such as monthly electricity consumption and / or hourly electricity bill. Hereinafter, look at in detail.

Referring to FIG. 2, the display 40 includes a first area 110 displaying at least one course of the washing machine 10 and a second area 120 displaying at least one information related to the washing machine. The first screen 100 or the main screen 100 may be provided. Furthermore, the first screen 100 may be provided with a third area 130 that provides various information related to the installation and / or setting of the laundry machine 10.

In recent years, the laundry machines, in addition to the preset course stored in the laundry machine from the time of shipment, may generate a course at random or modify the preset course and store the course as a user course. However, in order to recall the user course, a separate means, for example, a separate button should be selected. In addition, when the user course is displayed, the entire screen of the display is switched to display the user course. Such a method is inconvenient for the user to press a button directly, and furthermore, there is a problem in that other functions cannot be selected because the entire screen is switched and displayed. Therefore, a method for solving the above problems will be described with reference to the accompanying drawings.

4 is a conceptual diagram illustrating various zones displayed on the first area 110 of the first screen of the display 40.

Referring to FIG. 4, the user zone 1100 having at least one user course and the preset zones 1200, 1300, 1400 having at least one preset course of the washing machine are connected to each other to continuously change. It may be provided.

For example, the user area 1100 and the preset areas 1200, 1300, and 1400 may be disposed by providing a virtual background surface 1000 and partitioning the background surface 1000. In this case, at least one user zone 1100 and preset zones 1200, 1300, and 1400 may be provided. The drawing shows an example having one user zone 1100 and three preset zones 1200, 1300, and 1400, but this is only one example.

As described above, when the user zone 1100 and the preset zones 1200, 1300, and 1400 are disposed along the background surface 1000, the user zone 1100 and the preset zones 1200, 1300, and 1400 The first region 110 may be continuously changed or continuously scrolled to be sequentially displayed. That is, when the first preset zone 1200 is shown among the three preset zones 1200, 1300, and 1400 as shown in FIG. 4, when the background surface 1000 moves along the arrow A, the first zone ( In 110, a user course of the user area 1100 may be displayed.

Meanwhile, when the background surface 1000 moves, the moving process may be continuously displayed. That is, not all of the first area 110 in which the first preset area 1200 is displayed is switched to the user area 1100 at once, but the first preset area 1200 is moved as the background surface 1000 moves. The user area 1100 is slid from the left side of the first area 110 by sliding to the right of the first area 110 and enters the first area 110. When the user zone 1100 enters all of the first zones 110, the user zone 1100 is fixedly displayed in the first zone 110 and the preset zones 1200, 1300, and 1400 are not displayed. That is, when any one of the user zone 1100 and the preset zones 1200, 1300, and 1400 enter the first area 110 and is fixedly displayed, the other area is not displayed in the first area 110.

Meanwhile, the above-described virtual background surface 1000 may be provided to be transparent so that it is not actually seen. That is, when the background surface 1000 moves, the course icon 1210 provided in the preset zones 1200, 1300, and 1400 or the course icon 1120 of the user zone 1100 move in the eyes of the user. It is recognized. In addition, when the background screen is provided by the user's selection or the controller of the washing apparatus in the first area 110, the background screen continues to the first area 110 regardless of the movement of the background surface 1000 described above. Can be displayed. As a result, it may be defined that the background screen is provided in the first area 110 and the transparent background surface 1000 moves along with the course icons 1120 and 1210 in front of the background screen.

Accordingly, the first area 110 may display the user area or the preset area by continuously changing all parts instead of changing them at once, such as screen switching. The movement of the background surface 1000 or the switching of the first region 110 may be performed by selecting the moving regions 112 and 114 in FIG. 2 or 3. As illustrated in FIG. 2 or FIG. 3, the moving areas 112 and 114 may be illustrated in the form of arrows on the left and right sides of the first area 110. Therefore, when the user selects one of the moving areas 112 and 114, the background surface 1000 may move in the direction opposite to the arrow direction of the selected moving areas 112 and 114. That is, when the right side moving area 112 is selected, the background surface 1000 moves to the left side and the area placed on the right side of the first area 110 moves to the first area 110 to be seen. Meanwhile, although the drawing illustrates that the background surface 1000 is scrolled in the horizontal direction and displayed sequentially, the present invention is not limited thereto. For example, the background surface may be scrolled vertically to display sequentially.

Meanwhile, referring back to FIG. 2, the first screen 100 may include a second area 120 displaying at least one piece of information related to the laundry machine in addition to the first area 110. In this case, the second area 120 may be fixed to a predetermined position, for example, an upper portion of the first screen 100. That is, even when the user zone 1100 and the preset zones 1200, 1300, and 1400 continuously change in each other in the first zone 110, the second zone 120 may display preset information without conversion. .

For example, the second area 120 may include a zone display area 1200 that provides information about various zones displayed in the first area 110 and a device information area 1300 that provides information about a washing machine. It may include.

The zone display area 1200 indicates where the zone displayed in the first area 110 is located on the above-described virtual background surface 1000. That is, when the first preset area 1200 in which the preset course is displayed as shown in FIG. 2 is displayed, the preset course is displayed by the name 'LG Cycle'. In addition, the display unit 1210 is provided to correspond to the number of zones provided in the virtual background surface 1000. The number of the display unit 1210 may increase or decrease in correspondence with the number of zones provided in the background surface 1000. In FIG. 2, having four display units 1210 means that there are four zones on the background surface 1000. In addition, the second display unit 1210 on the left is displayed differently from other display units, for example, darker, so that the area displayed on the first area 110 may be recognized as the second in all four areas, that is, the second area from the left. have. In this case, when the user selects the left moving area 114, the first area of the background surface 1000 is illustrated as shown in FIG. 3. Here, since the first zone is a preset state as the user zone 1100, the user zone 1100 is displayed. Of course, the name of the zone display area 1200 is also changed to 'My Cycle' so that the user can recognize that the user course is displayed.

On the other hand, the device information area 1300 provides at least one piece of information about the laundry-device. For example, a wireless communication display unit 1310 for displaying a wireless communication state and a smart grid display unit 1320 for displaying a state of a so-called 'smart grid' may be provided. The display unit may be displayed in various symbols, symbols, figures, and characters, and may be displayed in the form of an icon as shown in the drawing.

The wireless communication display unit 1310 may include a wireless LAN icon 1312 indicating a connection state of a wireless LAN (WIFI) and a network icon indicating a connection state of a wireless sensor network such as a zigbee. 1314). That is, the laundry machine may include a wireless communication device (not shown) and display whether the wireless LAN is connected through the wireless LAN icon 1312. In addition, the laundry machine may include a wireless communication device corresponding to the wireless sensor network, and display whether the wireless sensor network is connected through the network icon 1314. Of course, it is also possible to have a wireless communication device corresponding to the wireless LAN and the wireless sensor network, respectively.

The smart grid display unit 1320 may include a smart grid icon to display various types of information according to a so-called 'smart grid'. The intelligent power grid is as follows.

The intelligent power grid means a system in which two-way communication is possible between a power source and / or a power plant that supplies power, except for being unilaterally supplied with electricity at a power source as in the related art. Therefore, the power source and the power plant can be notified to the power source and the power plant, and electricity can be produced and distributed according to the situation of the power source. The power source and / or the power plant can select an appropriate power supply source according to the situation of the power source and / or the power plant.

In addition, since the real-time communication about the power information between the power supplier and the consumer in the intelligent power grid is possible, the response of various consumers according to the power supply, that is, "real-time grid response" is possible. For example, when the price of power varies according to time zones or the price of power varies depending on the power supply company, the consumer can change or adjust the power consumption or power consumption time in consideration of such conditions. In addition, the power supplier can adjust the power price or the amount of power supply according to the response of the consumer.

Therefore, the intelligent power grid will have an energy management system (EMS) that is responsible for real-time power management and real-time prediction of power demand at the customer's destination, and an advanced metering infrastructure (AMI) that measures power consumption in real time. Can be. The energy management device and the measurement device may be configured as separate devices, or may be configured to perform the functions of both devices in one device.

Thus, the instrumentation used in the intelligent grid enables a consumer friendly efficiency concept such as "Prices to Devices". That is, real-time price information of the electric power market may be transmitted through an energy management device (EMS) installed in each home, and the energy management device (EMS) may control and communicate with an electric device provided in each home. Accordingly, the user can save power and energy by recognizing power information of each electric device by the energy management device (EMS) and performing power information processing such as power consumption amount or electric charge limit setting based on the power information. The above-described energy management device (EMS) is a local energy management device (Local EMS) used in the office or home, information collected by the local energy management device (Local EMS) by bidirectional communication with the local energy management device (EMS) It can be configured as a central energy management device (Central EMS) for processing.

It can be provided with an energy management device (2) connected to the two home appliances and control their operation. On the other hand, the electricity bill of each household can be charged as an hourly rate, and the hourly electricity bill becomes expensive in the time period when the power consumption is sharply increased, and the hourly electricity bill becomes cheaper at night time such as relatively low power consumption. Can be.

The energy management device 2 is connected to electrical appliances such as a refrigerator 6, a washing machine 10, an air conditioner 7, a TV 8 or a cooking appliance 9 through a network in the home. Bidirectional communication is possible. Communication inside the home can be via wireless or wired, such as a PLC. In addition, each electrical appliance may also be arranged to be connected to other electrical appliances to enable communication.

The energy management device 2 includes a display unit 3 for displaying electric power information and / or external environmental information, an input unit 4 that can be operated by a user, a communication unit (not shown) for transmitting and receiving information with an external device, and a clock ( It may be provided with a control unit (not shown). For example, the energy management device 2 may include a touch panel, and the display unit 3 may be provided on the touch panel.

In the intelligent power grid, the energy management device 2 may provide power information and / or external environment information through the display unit 3. Here, the power information is the current electricity consumption, the electricity bill, the expected charges based on the accumulated history, the energy information of the day such as carbon dioxide generation, the electricity bill of the section to which the current time belongs, the electricity bill of the next time period, and the electricity bill It may include at least one of the real-time energy information including the changing time interval. In addition, the external environment information may include at least one of information such as current weather, temperature, humidity, precipitation, wind. In addition, the power information may display a graph indicating a power consumption amount and / or a change in the time interval of the home appliance used, and may also show a graph of the electricity rate for each time period.

Such power information and / or external environmental information may be provided through the energy management device or may be provided through the display of the above-described laundry machine. That is, when the aforementioned smart grid icon is activated, the above-described various power information and / or external environment information may be provided through the display 40. To this end, the first screen 100 may be switched to a smart grid screen (not shown) capable of providing smart grid information. This screen switching may be performed when the user selects, for example, when the user selects the smart grid icon. Alternatively, when the smart grid information changes, for example, when there is a change in information such as an hourly electricity rate when using a washing machine, the controller of the washing apparatus may automatically display the information.

In this case, the energy management device and the laundry device may be configured to communicate by wire or wirelessly. In addition, when data is transmitted and received wirelessly, communication may be possible through the aforementioned WLAN or wireless sensor network. To this end, the energy management device and the laundry device may include a data transmitter (not shown) and a data receiver (not shown), respectively.

In addition, the third area 130 may further include an 'used course' icon 136 that displays a predetermined number of courses recently used by the user. The driver's course has a difference in that it is automatically stored by the controller compared to the above-described user course. That is, the controller of the washing apparatus may store a predetermined number, for example, up to three courses used by the user (hereinafter, only the case of storing up to three driver courses) will be described. Accordingly, when the user selects the driver's course icon 136, the controller may switch the first screen 100 to the driver's course display screen (not shown) to display up to three courses that have already been used. This is to eliminate the hassle of finding a course or modifying various information of a course when a user wants to reuse a recently used course. Accordingly, the controller may continue to store until three courses are already used by the user. On the other hand, if there are three courses already stored and the user selects a course again and uses the theta device, the controller deletes the first stored course sequentially and stores the new course as an article course.

Hereinafter, a step in which the user selects any one course in the preset zones 1200, 1300, and 1400 to drive the washing machine will be described with reference to the drawings.

As described above, Fig. 2 displays the preset course in the first area. The preset course may be displayed in various symbols, symbols, figures, and characters, and may be displayed in the form of an icon as shown in FIG. 2. In addition, the name of each course can be displayed together with the icon. At least one of the icon type and / or name may be changed. That is, the user may change the selection by selecting the 'set up' icon 132 described above.

In FIG. 2, six courses are displayed, including a 'Cotton / Normal' course. The number of courses represented by one preset zone 1200, 1300, 1400 is not limited and can be adjusted appropriately.

Meanwhile, when the user selects the cotton / normal course icon 1210 to perform washing by the cotton / normal course, the user may be switched to the second screen 200 displaying at least one information on the selected course.

FIG. 5 shows a second screen 200 or a course information display screen 200 (hereinafter, referred to as a 'course information display screen') for displaying information on cotton / normal course when the cotton / normal course icon is selected in FIG. 2. ).

Referring to FIG. 5, the course information display screen 200 may include a device information area 1300 that provides information about a washing apparatus as in the first screen 100 described above. Since the device information area 1300 has been described above, a detailed description thereof will be omitted.

Here, the time-related information may include at least one of an estimated time required for the selected course, an estimated time required for each administration, an estimated remaining time, an end delay time, and a start delay time. For example, although FIG. 5 includes an expected remaining time display unit 232 and a time delay selector 234, the present invention is not limited thereto.

The estimated remaining time display unit 232 displays the estimated remaining time for the course selected by the user. The controller of the washing apparatus calculates the estimated time required for the selected course and displays the estimated remaining time on the display unit 232 and displays the remaining time as time passes. The control unit may first calculate the estimated time according to the amount or the maximum amount of capacity mainly used by the user. This is because the user may select only the course first and do not put the laundry object into the drum yet. Therefore, the accurate estimated remaining time can be calculated by detecting the amount of dose when the user closes the door 60 and presses the drive and pause button 50 later.

On the other hand, the time delay selection unit 234 may delay the driving time of the washing machine by the user's selection. For example, the user may select the increase unit 235 of the time delay selector 234 to delay the driving time of the washing machine. FIG. 6 illustrates a case in which the driving time of the washing apparatus is delayed by one hour by the user selecting the increase unit 235 of the time delay selecting unit 234. The unit of time delayed in the case of selecting the increase unit 235 can be appropriately adjusted. For example, it can be set to delay 30 minutes or 1 hour for each selection. On the other hand, in the case where the driving of the washing machine is delayed by one hour, when the washing machine is normally driven without delay, the time delay may be reduced by selecting the reducing unit 236 of the time delay selecting unit 234. Similarly, when the reduction unit 236 is selected once, the time can be set to decrease by 30 minutes or 1 hour.

Referring to FIG. 5 again, the course information display screen 200 may include an additional information area 250 that displays at least one additional information on the selected course and may modify the additional information as described above.

The additional information that can be displayed in the additional information area 250 includes at least one of washing temperature, rinsing temperature, rinsing frequency, dehydration rate, contamination level, boiling degree, stain level, cold water washing, additional water supply, and softening agent.

The user may change the type and / or number of information displayed in the main area 2500 by selecting the aforementioned 'set up' icon.

On the other hand, the main area 2500 is provided with a display and correction area 2510 that can not only display the content of the additional information but also can be modified. The display and correction area 2510 can be implemented in various ways. For example, as shown in the drawing, a scroll bar 2512 is provided at one side to change a driving condition displayed by manipulation of the scroll bar 2512. have. FIG. 7 is a diagram illustrating a state in which the pollution degree displayed on the main region 2500 is corrected.

Referring to FIG. 7, when the user corrects the degree of contamination of the laundry object, the user manipulates the scroll bar 2512 of the degree of contamination display and correction area 2510 that displays the degree of contamination. For example, the degree of contamination may be adjusted from 'normal' to 'heavy' by manipulating the scroll bar 2512. That is, the value of the driving condition displayed in response to the manipulation of the scroll bar 2512 is changed. Since the remaining information included in the main area 2500 can be modified in a similar manner, repeated description thereof will be omitted.

Meanwhile, referring back to FIG. 5, in the present embodiment, information on the degree of boiling, the number of rinsing, the degree of staining, additional water supply, whether the cold water is washed, and whether the softening agent is added may be displayed on the auxiliary area 2600. Like the main area 2500, the number of information displayed on the sub area 2600 can be appropriately adjusted and is not limited to the six shown in the drawing. In addition, the type and number of driving conditions or additional information displayed on the auxiliary area 2600 may be selected by a user's selection. The user may change the type and / or number of information displayed on the auxiliary area 2600 by selecting the above-mentioned 'set up' icon.

As described above, the auxiliary area 2600 may be regarded as having a lower utilization than the additional degree or driving conditions displayed on the main area 2500. Therefore, since the area of each area of the displayed information may be narrower than that of the main area 2500, it is difficult to provide a sub-region 2600 that can be simultaneously displayed and modified like the main area 2500. Accordingly, the auxiliary area 2600 includes a display unit 2610 for displaying additional information or driving conditions, and the auxiliary window capable of correcting the selected additional information when the user selects additional information or driving conditions that need correction. It can be configured to be generated.

FIG. 8 is a diagram illustrating a case of modifying the degree of life displayed on the auxiliary area 2600.

Referring to FIG. 8, when the user wants to change the degree of boiling (boiling time) during the additional information or driving conditions displayed on the auxiliary area 2600, the user may select the degree of boiling display 2610 that displays the degree of boiling. have. In this case, the auxiliary window 2612 may be generated to change the degree of life. As shown in FIG. 8, the auxiliary window 2612 may be provided to change the boiling time in units of 15 minutes, 30 minutes, 45 minutes, 60 minutes, 120 minutes, and 180 minutes. Boiling time provided in the auxiliary window is of course adjustable. 8 is a diagram illustrating a case in which the user selects 30 minutes in the auxiliary window of the degree of boiling. As shown in FIG. 9, when the user selects 30 minutes, the degree of life (boiling time) is displayed as '30 minutes'. Furthermore, if the degree of boil is set to 30 minutes, the driving time of the washing machine is increased, and thus the estimated remaining time also changes according to the change of the additional information. That is, when the degree of boil is set to 30 minutes and the driving time is increased by 30 minutes, the estimated remaining time displayed on the estimated remaining time display unit 232 may also be increased by 30 minutes. Other additional information or driving conditions displayed on the auxiliary area 2600 may also be changed in a similar manner to the above-described method, and thus repetitive description thereof will be omitted.

Meanwhile, referring back to FIG. 5, the course information display screen 200 may include a storage and deletion area 270 for selecting to save or delete the selected course. This is an area in which the user can save a preset course selected by the user as a user course or delete a course already selected as the user course from the user course.

5 illustrates a case in which one of the preset courses is selected as described above. In this case, the storage and deletion area 270 may display a storage selection unit 274 that inquires whether to save or not. This is because even a course already stored as a preset course can be stored as a user course by the user's selection. In this case, as described above, the user may change the icon and / or name of the user course. Meanwhile, when any one of the information, additional information, or driving conditions displayed on the course information display screen 200 is changed as shown in FIG. 6, 7, or 9, the storage and deletion area 270 inquires whether to store or not. The storage selector 274 may continue to be displayed. This is because it is preferable to ask the user whether to save as a user course because the driving conditions, additional information, etc. have been changed.

FIG. 10 shows a display when the user starts the driving of the washing machine by pressing the drive and pause button 50 while the user inserts the laundry object into the drum in the state of FIG. 5 and closes the door.

Referring to FIG. 10, when the washing apparatus starts to drive, the display 40 includes a third screen 300 or a driving display screen 300 which displays at least one piece of information related to washing during driving.

The driving display screen 300 may include a driving display area 310 displaying at least one of a selected course, an estimated remaining time, and a corresponding stroke.

At a predetermined position, for example, an upper portion of the driving display region 310, a name display region 312 may be provided to display a name and an icon of a selected course.

In addition, the driving display area 310 may include a remaining time display area 314 that displays an estimated remaining time. The remaining time is displayed according to the selected course, the amount of laundry and the passage of time.

Furthermore, the drive display area 310 may include a stroke display area 316 for providing information on the stroke. The administration display area 316 may provide information such as a washing stroke, a rinsing stroke, a dehydrating stroke, and / or a drying stroke, as well as detailed information such as a quantity detection state, a washing water supply state, and a detergent supply state. In FIG. 10, the user indicates that the amount of the amount of the amount of the amount of detected amount is detected as the user presses the driving and pause button 50. The controller may detect the correct amount of quantity through the quantity of detection and display the accurate estimated time according to the detected amount of quantity. In addition, a separate message window 340 may be generated to indicate that the door 60 is closed.

Meanwhile, the driving display screen 300 may include a 'home' area 320 that may return to the first screen 100. When the user selects the home area 320, the driving display screen 300 is switched to the first screen 100. However, when the washing apparatus is being driven, the home region 320 may be deactivated. This is to prevent the user from returning to the first screen and changing the washing course by selecting the home area while the washing apparatus is being driven. On the other hand, when the user pauses the driving of the washing machine by pressing the drive and pause button 50 during the driving of the washing machine, the home area 320 may be activated. This provides an opportunity to return to the first screen 100 because the driving of the washing machine is paused by the user's selection.

Meanwhile, the driving display screen 300 may further include a child lock display unit 330 indicating whether or not a child lock is used to prevent a laundry machine from malfunctioning by operating a laundry machine. have. The activation of the child lock function may be activated when another operation unit provided in the control panel, for example, the driving and pause button 50 is pressed for a predetermined time. The release of the child lock may be released in the same manner as the activation, for example, when the driving and pause button 50 is pressed for a predetermined time.

When the quantity detection is finished, it can be inquired whether the laundry object is added as shown in FIG. 11. Further inquiries of the laundry object may be made through the above-described administrative display area 316. That is, when the quantity detection is finished, the control unit finally inquires whether to add the laundry object before driving the washing apparatus according to the selected course. At this time, if there is a laundry object to be added by the user can be added by opening the door 60. When the opening of the door 60 is detected, the control unit may again detect the amount of water and reflect the added laundry object to calculate and display the estimated remaining time again. On the other hand, if the opening of the door 60 is not detected for a predetermined time, the controller determines that there is no additional laundry object and drives the washing apparatus according to the selected course.

On the other hand, the driving display area 310 may further include a time display area 318 that can visually display the required time and the remaining time during the driving of the laundry machine. For example, the time display area 318 may be provided along the edge of the driving display area 310 as shown in FIG. 11. Accordingly, the time display area 318 may be illustrated so that the user can recognize the required time and / or remaining time as time passes. That is, as shown in the drawing, bars 319 of different colors may progress along the time display area 318 to fill the time display area 318 with the bar in proportion to the passage of time. have. Therefore, the user can check the remaining time numerically through the remaining time display area 314, and how much time has elapsed and how much time remains in the total time required through the time display area 318. Can be intuitively recognized.

12 illustrates a state in which the washing apparatus is driven according to the selected course.

12 shows a case where the washing administration of the selected course is in progress, for example. That is, in the case where the washing apparatus performs the washing administration, a 'washing' sentence indicating the washing administration may be displayed on the administration display area 316.

On the other hand, the user may temporarily stop the driving of the washing machine by various factors while the selected course is being performed. For example, there is a case in which a laundry object is to be additionally introduced, or a case in which a bag of laundry is difficult to be immersed in water, or the like. In the case described above, the user can stop the driving of the washing machine by pressing the driving and pause button 50. However, if the user stops driving the washing machine and does not drive the washing machine again for a predetermined time or more, the smell may remain on the washing object. Particularly, when the washing water remains in the inside of the washing machine, if the driving of the washing machine is stopped for a long time for a predetermined time or longer, odor or the like may remain on the washing object and wrinkles may occur. Therefore, as described above, the control unit of the washing apparatus takes measures to protect the laundry object when the washing apparatus stops for a predetermined time or more while driving.

16 is a flowchart illustrating a control method that may be performed by the controller.

Referring to FIG. 16, in the method of controlling a washing apparatus, a step of performing a selected course (S1610), a step of waiting for a suspension command (S1630), and a process of stopping a course of the selected course according to the suspension command for a first time ( And determining whether to drain the wash water inside the tub by detecting an input of a re-execution command of the selected course during the first time (S1650). Since the steps for performing the selected course have already been described, the following steps will be described.

As described above, the controller of the washing apparatus may wait for a command for suspending the course while performing the selected course (S1630). The suspend command can be implemented in various ways depending on the washing apparatus. For example, a pause button may be provided on the control panel of the washing machine so that a pause command may be input by manipulation of the button. Alternatively, the course selected by the manipulation of the button is performed by the driving and the pause button 50 as in the present embodiment, and the manipulation of the button may be input as a suspending command during the course.

13 illustrates a case where a suspend command is input while driving the washing apparatus.

Referring to FIG. 13, when a pause command is detected, a phrase 'Pause' may be displayed in the administration display area 316 indicating that the driving of the washing machine is stopped. The controller may stop the progress of the selected course for a predetermined first time when a suspension command is detected during the progress of the selected course (S1650). In this case, the first time may be appropriately set, for example, about 5 to 10 minutes.

Subsequently, the controller may wait for an input of a re-execution command requesting to perform the selected course again during the first time. In addition, by detecting the input of the re-execution command it may be determined whether to wash the wash water in the tub (S1670).

That is, the controller may wait for the re-execution command to be input by the operation of the driving and pause button 50 during the first time. If a re-execution command is input during the first time, the controller may again perform the remaining stroke of the selected course. However, the user may not input a re-execution command during the first time. Accordingly, the controller may inform that the wash water in the tub is drained and the selection of the selected course may be deleted if the re-execution command is not input before the second time before the first time ends. For example, approximately one minute before the end of the first time, you can visually or acoustically announce a phrase such as "Your course selection will be deleted within one minute. To continue the selected course, press the Start and Pause button." You can inform. 14 illustrates a state in which the above phrase is displayed through the message window 1340. In addition, although not shown in the drawing, if the re-execution command is not input within the predetermined time may inform that the wash water in the tub may be drained.

Despite the above notification, if the user does not input a re-execution command during the first time, the controller first checks whether the wash water remains in the tub. For example, if the time point at which the course is stopped is the washing administration, the controller determines that the washing water remains inside the tub. In addition, the control unit determines that no washing water remains in the tub in the case of the dehydrating stroke and / or the drying stroke. On the other hand, in the case of the rinsing stroke, since the water supply and drainage are repeated, the control unit detects the driving of the water supply valve and the driving of the drain valve to determine whether the wash water remains in the tub. That is, if the course of the course is stopped without driving the drain valve after driving the water supply valve in the rinsing stroke, the controller determines that the wash water remains inside the tub. In addition, when the course of the course is stopped before the water supply valve is driven after the drain valve is driven in the rinsing cycle, the controller determines that no washing water remains in the tub.

If the re-run command is not input for the first time and it is determined that the wash water remains inside the tub, the controller may drain the wash water inside the tub. This is to prevent the laundry object is immersed in the wash water for more than a predetermined time as described above, so that smells and the like remain and wrinkles become severe. In addition, the controller may delete the selected course at the same time as draining the wash water. That is, when draining the wash water, it is difficult to re-run the course that was previously performed, so the selection of the course is deleted. In addition, when such an operation is made, the user may be visually or acoustically informed of the drainage of the wash water and / or the deletion of the course selection.

On the other hand, Figure 15 shows a case in which the re-execution command is input within the predetermined first time and the selected course is re-executed to complete the driving of the washing machine.

Referring to FIG. 15, a 'Complete' message indicating that driving is completed may be displayed in the remaining time display area 314. In addition, the time display area 318 is all filled by the bar (bar) described above, the user can recognize that the operation of the washing machine is completed. Meanwhile, when driving of the washing apparatus is completed, the driving display screen 300 may display the storage display unit 350 inquiring whether to store the selected course. However, when the selected course corresponds to the user course and the user course is performed without modifying the information of the user course, the above-described storage display unit 350 is not displayed because the course is already stored as the user course. On the other hand, if the driving is terminated by selecting any one of the preset courses, or if at least one of washing information, additional information or driving conditions is modified even in the user course, the course is not yet stored as the user course. The storage display unit 350 may be displayed. When the user selects the storage display unit 350, the selected course is stored as a new user course.

On the other hand, the description of the washing machine described above was described as the case of the washing machine to perform the washing, but is not limited thereto. For example, it may be sufficiently applied even in the case of a dryer for drying or a combined-use washing machine for drying and washing.
