It includes a refresh unit (C1) to perform, a reservation unit (C2) to input a reservation command to perform a course at a specific time, and an additional function unit (C4) to utilize additional additional functions such as pairing with other devices. can do.

In addition, the setting unit P2 may further include an anti-wrinkle unit E that executes an anti-wrinkle course to prevent the clothing from being wrinkled when the course is finished.

In the setting unit P2, a function that can be utilized at the present time or a function selected by the user may be turned on, and a function that cannot be executed or not selected by the user may be turned off.

The setting unit P2 may display all of the above contents through the auxiliary display P19.

Fig. 10 shows an aspect of the control panel p when operating the laundry treatment apparatus of the present invention.

Referring to FIG. 10(a) , the clothes handling apparatus is in a state in which power is cut off and the display unit P8 and the auxiliary display P19 are turned off.

The user may supply power to the laundry treatment apparatus including the display unit P8 and the auxiliary display P19 by inputting the power supply unit P46.

Referring to FIG. 10(b), power is supplied to the control panel P, and the manipulation unit P7 can be activated. The user can select a desired course by rotating the control unit p7, and can select a desired option by confirming or inputting the auxiliary display P19.

The selected course and option may be displayed on the display unit P8, and the selected additional option or function may be displayed on the auxiliary display P19.

The user can perform the courses and options by inputting the execution unit P47.

Referring to FIG. 10(c), the display unit P8 may display the course and option performance states, and the auxiliary display P19 may display the current option state. For example, when an additional function such as steam is used, the steam unit C3 may be turned on. In addition, if the energy amount of the course is medium and the drying degree is set to be low and the drying course is performed, it can be indicated that the moisture content is high and the drying time is not particularly limited.

Referring to FIG. 10(d), completion information indicating that the courses and options have been completed may be displayed on the display unit P8. Thereafter, the control panel p may be powered off.

Based on the information displayed on the display unit P8, the user can select a course or option, determine a course or option, and grasp the course or option's performance status and the end state of the course or option at once.

FIG. 11 shows the usability of the display unit P8, and the display unit P84 is highlighted in the display unit P8.

Referring to FIG. 11(a), when power is input to the control panel P, the name and description of the selected course or option are written in the content display area D2 of the display unit P8 or display P84. and information on the number of courses or options that can be changed can be displayed in the status display area D1.

The content display area D2 may be disposed below the status display area D1 and may have a larger area than the status display area D1. Therefore, the content display area D2 can actively convey necessary information to the user by using text and icons.

The status display unit D1 can intuitively convey information through a symbol such as an icon or sign.

The input area D3 may be disposed under the content display area D2. Accordingly, it is possible to prevent the user's body from covering the content display area D2 when the user touches the input area D3.

The input area D3 can display information by which the user can determine the information displayed in the content display area D2. That is, when it is necessary to receive a command requiring confirmation or decision by the user through the selector R, the input content corresponding to the selector R can be displayed in the input area D3. .

For example, it is not an arbitrary course or option set as default that can be selected by rotating the control unit P7, but a recommended course or option provided by a manufacturer, a course or option that has been used more than N times recently, or a course or option previously set by the user. An indication that a course or option in the form of a master card additionally stored in the control unit, such as a setting course or option, can be selected may be displayed in the input area D3.

The master card may correspond to new courses or options provided by the server or set by a user changing an option value for a specific course, which is different from any course or option basically set when the clothes handling machine is purchased. .

Referring to FIGS. 11(b) and 11(c) , the display unit D84 may display confirmation contents confirming a command additionally input by the user. The confirmation may be to enlarge and display the name or effect of the command input by the user.

For example, if the user inputs the steam part C3 of the setting part P2, the steam part C3 is turned on in the auxiliary display P19 and the steam is turned on in the display P84. etc. appears in a large size to indicate to the user that the steam function has been activated.

In addition, when the user inputs the steam part C3 of the setting part P2 again, not only the steam part C3 is turned off in the auxiliary display P19, but also the steam is turned off in the display P84. A message appears to indicate to the user that the steam function has been deactivated.

In this way, the user can intuitively check what the command he/she inputs and whether or not the user's command is properly input through one display P84. Accordingly, the user can accurately determine whether or not the corresponding command has been input, even without a separate display device that separately displays whether or not the corresponding command has been received.

Referring to FIG. 11(d), when waiting for a certain period of time or when the selector R is input, the selected course and option may be displayed on the display P84. In this way, the user can confirm that his or her command has been reflected, and can execute the selected course and option without delay in course execution.

12 illustrates an embodiment of selecting a course or option.

In the control panel (P), any courses or options provided by default may be stored. However, the user can use it repeatedly by continuously adding a specific option in a specific course.

In addition, a manufacturer or the like may research the weather, installation area, characteristics of the clothes handling device, and the like, and may have courses or options that are recommended to the user.

However, if the user repeatedly sets these courses or options, it may be very cumbersome, and the user may not be aware of the existence of the courses or options and may not be able to use them.

Accordingly, the control panel P of the laundry treatment apparatus of the present invention may store a new course or option other than the basically set course or option separately in the form of a shortcut.

For example, a newly set course or option may be sequentially displayed on the display P84 by input of the manipulation unit P7. Accordingly, since new course or option types are sequentially displayed on the display unit P84, it can be defined as a master card.

That is, the master card may be one of newly set courses and options, unlike the basically provided courses and options. The master card may be provided in plurality, and the order in which they are sequentially displayed may be set in advance.

For example, a course frequently used by the user or a master card corresponding to a course previously set by the user may be displayed first, followed by courses that may be recommended.

Referring to FIG. 12 (a), a standard drying course, which is one of a basically provided course or an option, may be displayed on the display P84.

At this time, the user can select the master card displayed in the input area D3 with the selector R.

Referring to FIG. 12(b), the first master card may be displayed on the display P84. The first master card may be an option that the user frequently uses recently.

The user can perform the course corresponding to the master card by inputting the execution unit. However, the user can select another master card by rotating the control unit p7.

Referring to FIG. 12(c), when the user rotates the manipulation unit p7, a second master card may appear. For example, when the laundry treatment device has a steam function, an option in which steam is added may be recommended.

Referring to FIG. 12(d), when the user rotates the manipulation unit p7 again, a third master card may appear. For example, a speed drying course that can compress drying time as much as possible than a general drying course may appear. This increases the temperature or the flow rate of hot air, and can be applied when the material of the clothing is strong in durability.

In this way, the user can sequentially check the stored master cards by rotating the control unit p7, and when all of them are confirmed, the first master card can appear again.

Accordingly, in the laundry handling apparatus of the present invention, a desired course and option can be quickly selected through the control unit p7 even if an input unit for inputting a separate course or option is not provided.

Fig. 13 shows that the laundry treatment apparatus of the present invention performs a wrinkle prevention operation.

Referring to FIG. 13 (a), when the wrinkle prevention process is performed, the drum rotates intermittently.

In this way, it can be prevented that the position of the clothes is changed on the drum 2 so that a specific position of the clothes is pressed or wrinkled.

However, if the rotation time of the drum is too long or if the drum rotates repeatedly more than necessary, energy consumption is severe and the user may mistakenly think that the drying cycle is not over.

Therefore, in the anti-wrinkle process, the time during which the drum stops may be set longer than the time during which the drum rotates. For example, in the anti-wrinkle process, the rotating time of the drum may be set to be three times longer than the stopping time of the drum.

In the anti-wrinkle operation, the rotation rpm of the drum may be set lower than the speed at which the clothes adhere to the inner wall of the drum and rotate. As a result, wrinkles caused by pressing a specific part of the clothes as the location or shape of the clothes are repeatedly changed inside the drum can be prevented.

Referring to FIG. 13(b), the rotational direction of the drum 2 may be continuously changed in the anti-wrinkle process.

For example, if the drum 2 rotates to the left and stops, then the drum 2 can rotate to the right and stop.

As a result, since the shape or position of the clothes is changed more than when the clothes are rotated to one side, the occurrence of wrinkles on the clothes can be prevented.

Meanwhile, in the anti-wrinkle process, since the drum 2 rotates, the door 112 may be kept in a locked state. Therefore, it is necessary to notify the user that wrinkle prevention is being performed even though the course has been completed.

In addition, since the anti-wrinkle process is performed in a situation in which the user cannot withdraw the clothes for a predetermined period of time or longer even after the course is completed, it may not be necessary to perform the process in a situation where the user can operate the laundry treatment device. This is because it is a situation in which the user can expect to withdraw clothes.

On the other hand, the wrinkle prevention process may be set not to be performed for a specific time or longer. This is because when the user is away for a long time, if the wrinkle prevention process is performed without interruption, standby power consumption is severe, resulting in energy waste.

For example, the specific time may be set to 4 hours or less.

14 shows the state of the display unit during the wrinkle prevention process.

Referring to FIG. 14(a) , when the course and option are performed in the laundry treatment apparatus, status information D2a of the course and option being performed may be displayed on the display P84. The status information D2a may display the names and remaining time of the courses and options.

Referring to FIG. 14(b), when the courses and options are completed, completion information D2b indicating that the courses and options have been completed may be displayed on the display P84.

Meanwhile, in the course and option process, the door 112 may be locked to the cabinet 1 . In addition, when the courses and options are completed, the door 112 may be unlocked from the cabinet 1 .

However, if the door 112 is not opened for a certain period of time even though the courses and options are completed, the laundry treatment apparatus of the present invention may perform an anti-wrinkle operation in which the drum is intermittently rotated to prevent the clothes from being wrinkled.

In addition, the laundry treatment apparatus of the present invention can perform the wrinkle prevention process even when the course and option are finished when the wrinkle prevention unit E is input in the setting unit p12 or the like.

Referring to FIG. 14(c), when the anti-wrinkle process is performed, performance information D2c indicating that the anti-wrinkle process is being performed may be displayed on the display P84. For example, the performance information D2c may correspond to a phrase or icon indicating a state in which the drum is additionally rotated to prevent wrinkles after the course is completed.

Thus, the user can also know that the drying course has been completed. Accordingly, it can also be recognized that the locking of the door is for the anti-wrinkle process and not for performing the drying course. As a result, it is possible to recognize that the user may stop the wrinkle prevention operation at any time.

Referring to FIG. 14(d), when the wrinkle prevention process is also completed, withdrawal information D2d indicating that the wrinkle prevention is completed and the clothes are taken out may be displayed. At this time, the door 112 is unlocked so that the user can open the door 112 and take out clothes from the drum 2 at any time.

Referring to FIG. 14(e), when the operation of the laundry treatment device, such as the anti-wrinkle operation, is finally completed, guidance information D2e to open the door 112 and ventilate may be displayed on the display D84.

15 shows the state of the control panel during the anti-wrinkle process.

Referring to FIG. 15 (a), the display D84 may display the performance information D2c.

At this time, the door 112 is locked, and the drum 2 may rotate intermittently.

However, when the user is near the clothes handling machine, he/she may want to take out the clothes from the drum 2 . This is because the wrinkle prevention information is performed when the course is finished, and drying of the clothes is finally completed.

Referring to FIG. 15(b), the user may touch or press the control panel p to end the wrinkle prevention process.

For example, the user may press or touch one or more of the power supply unit P46, the execution unit P47, the setting unit P2, and the wrinkle prevention unit E.

When the control panel (p) presses or touches the power supply unit (P46), the execution unit (P47), the setting unit (P2), and the anti-wrinkle unit (E) during the anti-wrinkle process, the anti-wrinkle process is immediately terminated. and unlock the door.

In other words, even if the user inputs the power supply unit P46, the power is not simply terminated, but the power may be terminated while the door is unlocked.

Thus, the user can take out the clothes from the drum 2 without waiting for the wrinkle prevention process to be completed.

16 shows an embodiment of a control method for performing an anti-wrinkle process.

The laundry handling apparatus according to the present invention may perform an arbitrary course and option and perform an end step (N1) of ending the course and option.

When the end step (N1) is performed, a determination step (N2) of detecting whether or not the wrinkle prevention unit (E) has been touched on the control panel (P) or whether the anti-wrinkle operation is set to be performed may be performed (N2). .

When there is no command for performing the anti-wrinkle operation in the determination step (N2), a release step (N9) of unlocking the door may be performed.

On the other hand, if it is determined in the determination step (N2) that the wrinkle prevention operation is to be performed, a locking step (N3) of maintaining the lock of the door or re-locking the door may be performed.

Thereafter, in the laundry treatment apparatus of the present invention, the performing step N4 of performing the wrinkle prevention operation may be executed. In the performing step (N4), the drum rotates intermittently, and the rotation direction of the drum may be alternately changed. As a result, the drive unit additionally rotates the drum 2 when the course or option ends, thereby preventing the clothes from being wrinkled. The additional rotation of the drum 2 means that the driving unit is additionally operated even after completing the set course. When the additional rotation of the drum is completed by the drive unit, the display unit may display that the additional rotation of the drum is completed, and supply of power may be stopped.

In addition, in the performing step (N4), the entire rotating time of the drum 2 may be set shorter than the stopping time of the drum 2.

The display unit (N8) may perform a notification step (N5) of displaying performance information that the wrinkle prevention operation is performed. In addition, in the notification step (N5), the display unit (P8) can display status information indicating that the door is locked. That is, it can be seen that the performance information includes the status information.

Meanwhile, the laundry treatment apparatus of the present invention may perform a power sensing step (N6) of detecting whether or not the user inputs the power supply unit (P46) while performing the wrinkle prevention operation. When the power unit is input in the power sensing step (N6), the laundry treatment apparatus may perform the stopping step (N8) of stopping the wrinkle prevention operation and the release step (N9).

However, if the power supply unit is not input, the laundry treatment apparatus according to the present invention may perform an additional detection step (N7) whether there is an input from the control panel P while the wrinkle prevention operation is performed.

When it is detected that the user manipulates the control panel (p) in the additional detection step (N7), the laundry treatment apparatus of the present invention performs the stopping step (N8) of stopping the wrinkle prevention operation, and the releasing step (N9). ) can be performed.

Manipulating the control panel P means that the user is near the laundry treatment device, and manipulating the control panel P during the anti-wrinkle process means that the user intends to end the anti-wrinkle process. because it means

In the additional sensing step (N7), when the manipulation unit (P7), the setting unit (P2), and the selection unit (R) are input, the laundry treatment apparatus may perform the interrupting step (N8).

The stopping step (N8) may mean stopping the rotation of the drum 2 by the drive unit. Also, when the stopping step (N8) is performed, the unlocking step (N9) is performed so that the locking unit (L) can release the lock of the door.

On the other hand, when a specific time elapses without a separate input in the power sensing step (N6) and the additional sensing step (N7), the completion step (N10) of terminating the wrinkle prevention process may be performed.

When the completion step N10 is performed, the laundry handling apparatus may perform a display step N11 of displaying the completion information on the display unit N8. Thereafter, the releasing step (N9) may be performed. As a result, when the further rotation of the drum 2 is completed by the drive unit, the display unit P8 indicates that the additional rotation of the drum has been completed and the supply of power can be stopped.

On the other hand, when the completion step (N10) is performed, the display step (N11) may be omitted and the release step (N9) may be immediately performed. The fact that the completion step N10 has been performed can be regarded as a state in which the user has not already checked the laundry treatment device. Therefore, even if the display step (N11) is performed, there is a high probability that the user will not be able to confirm it.

Accordingly, the display step N11 is omitted, the release step N9 is immediately performed, and then the power supply to the laundry treatment apparatus may be cut off.

As a result, when the additional rotation of the drum 2 is completed by the driving unit, the display unit p8 does not display completion information and power supply can be cut off.

Since the structure, control method, and assembly method of the interface and the laundry treatment apparatus described above are only for explaining an example of the interface and the laundry treatment apparatus, the scope of rights of the present application is not limited to the above-described embodiment.
