Description

CROSS-REFERENCE TO RELATED APPLICATION(S)

This application claims the benefit of Korean Patent Application No. 10-2023-0101605, filed on Aug. 3, 2023, which is hereby incorporated by reference as if fully set forth herein.

TECHNICAL FIELD

The disclosure relates to a laundry treatment apparatus, and more particularly, to a laundry treatment apparatus including an output part that outputs a screen.

BACKGROUND

A laundry treatment apparatus is a device that performs a laundry treatment process, such as removing contamination from laundry by putting clothing, bedding, and so on (hereinafter, referred to as laundry) into a drum.

The laundry treatment apparatus may perform processes such as washing, rinsing, spinning, and drying laundry. Laundry treatment apparatuses may be classified into a top loader type and a front loader type depending on how laundry is into a drum.

The laundry treatment apparatus may include a cabinet forming the exterior thereof, a tub accommodated inside the cabinet, a drum rotatably mounted inside the tub and receiving laundry, and a detergent supply supplying detergent into the drum.

In the case where the laundry treatment apparatus is provided to wash laundry, when the drum is rotated by a motor while water and detergent are supplied to laundry contained in the drum, dirt on the laundry may be removed by friction between the drum and the washing water.

The detergent supply is equipped with a detergent supply function to enhance the washing effect. Detergent refers to a substance that enhances the washing effect, such as fabric detergent, fabric softener, and fabric bleach. The detergent may be in a powder form or a liquid form.

In the case where the laundry treatment apparatus is provided to dry laundry, the laundry treatment apparatus may remove moisture from the laundry by providing dry air to the laundry.

The laundry treatment apparatus may be configured to include the cabinet, the drum rotatably provided inside the cabinet, and a heater for heating or drying air provided to laundry.

As dry air is supplied to the laundry contained in the drum, moisture may be evaporated from the laundry by the dry air, thereby removing the moisture from the laundry.

The laundry treatment apparatus may provide various options for laundry treatment courses such as washing or drying, so that a user may adjust the options.

For example, the wash course may be provided with wash options which enable adjustment of various conditions for the wash course, such as the temperature of washing water, the number of rinses, and the number of spins, and the dry course may be provided with dry options which enable adjustment of various conditions for the dry course, such as a laundry amount and a dry intensity level.

The laundry treatment apparatus may provide various means by which the user adjusts the options. A relevant document KR 10-2023-0001307 A1 discloses an option display part for displaying course options that a user may adjust for a treatment course.

However, a laundry treatment apparatus in the relevant document provides the option display part with buttons, which is separate from an output part. This scheme may reduce use convenience by increasing the number of objects that the user should recognize to check information or manipulate to input a command.

To overcome the above shortcomings, a laundry treatment apparatus has been developed, which may provide option information and allow options to be set on a screen output from an output part.

In this case, the output part may display various options which may be set for laundry treatment courses on a screen, and the user may select and set an option on the screen.

The output part may output a course selection screen displaying a plurality of treatment courses for laundry treatment. When a plurality of options are displayed on the course selection screen, visibility may be reduced or a limited number of options may be displayed due to a limited screen size. Accordingly, the output part may output an option display screen displaying a plurality of options separately from the course selection screen.

However, identifying option information or setting an option using the option display screen which has been output by selecting any one treatment course on the course selection screen may require switching between a plurality of screens, thereby reducing use convenience.

Moreover, when the output part separately outputs an option setting screen for changing the setting values of options, the number of screens to be output for option settings may further increase, which increases inconvenience.

Certain options may be more important for some of the plurality of treatment courses, displaying all options on the option display screen as described above may make it difficult to distinguish options of high importance or different characteristics from each other, and accessibility to highly important options may be reduced. Therefore, use convenience may be decreased.

Therefore, it is an important issue in the technical field of the disclosure to provide a laundry treatment apparatus for providing a user with a more efficient and convenient option setting process and providing visibility and accessibility for a specific option depending on a treatment course.

The plurality of course objects D103 may be arranged along one direction on the course selection screen D20. For example, the plurality of course objects D103 may be arranged along the width direction, height direction, or diagonal direction of the cabinet 11.

A course object D103 other than the course object D103 representing the target treatment course D120 may be disposed on one side and/or the other side of the course object D103 representing the target treatment course D120. Among the plurality of course objects D103, the course object D103 representing the target treatment course D120 may be displayed in a larger size than the other course objects D103.

The course object D103 representing the target treatment course D120 is shown in FIG. 15 as being displayed in a larger size than the other course objects D103 and including an expected time D105 required to complete the treatment course, distinguishably from the other course objects D103, to which the disclosure is not necessarily limited.

The target treatment course D120 may be changed to another one of the plurality of treatment courses through the input part 120. The user may change the course object D103 corresponding to the target treatment course D120 through the input part 120 or the like.

For example, the user may change the target treatment course D120 in various manners such as generating a manipulation signal by sliding on a screen D1 of the output part 110 or selecting a course object D103 representing an intended treatment course to be displayed as the target treatment course D120.

The shortcut option D209 may be displayed included in the course object D103. That is, the shortcut option D209 may be displayed as a portion of the course object D103 or inside the course object D103. Accordingly, the user may easily identify the course object D103 for which the shortcut option D209 is.

In an embodiment of the disclosure, the course object D103 may include a border portion D109 displayed to define the border of the course object D103, and the shortcut option D209 may be displayed inside the border portion D109 of the course object D103.

The border portion D109 may define the boundary of the course object D103. However, the border portion D109 may define only a portion of the boundary of the course object D103, when needed. The shortcut option D209 may be displayed as a selectable object within an area surrounded by the border portion D109.

Some of the plurality of treatment courses on the course selection screen D20 may correspond to shortcut courses CS for which shortcut options D209 are displayed, and shortcut options D209 may not be displayed for the other treatment courses.

The shortcut courses CS may refer to treatment courses for which shortcut options D209 are displayed on the course selection screen D20, and the other treatment courses may refer to treatment courses for which shortcut options D209 are not displayed.

The shortcut options D209 may be preset for the shortcut course CS and not for the other treatment courses in the controller 70. The shortcut options D209 may be made during the manufacture of the laundry treatment apparatus 1 or in a user-set use environment.

In an embodiment of the disclosure, as illustrated in FIG. 15, a general course object D103 other than a course object D103 representing a shortcut course CS may be displayed such that it indicates a course name D104 and an expected required time D105, whereas the course object D103 representing the shortcut course CS may display a shortcut option D209 instead of an estimated required time D105. However, this is only an example of the disclosure, and it is also possible to display the shortcut option D209 together with the expected required time D105.

In an embodiment of the disclosure, the shortcut option D209 may be displayed only on the course object D103 representing the target treatment course D120. Accordingly, the course selection screen D20 may minimize unnecessary information and improve visibility for the user.

Further, as described above in an embodiment of the disclosure, the shortcut option D209 may be displayed only for the shortcut course CS. Accordingly, when the shortcut course CS is displayed as the target treatment course D120 on the course selection screen D20, the shortcut option D209 may be displayed on the course selection screen D20.

The user may easily identify whether the target treatment course D120 is a shortcut course CS depending on whether the shortcut option D209 is displayed on the course object D103 representing the target treatment course D120, and recognize the importance of the shortcut option D209.

FIG. 16 illustrates a process of setting a shortcut option D209 on a course selection screen D20 by the user. FIG. 16(a) illustrates a course selection screen D20 with a shortcut option D209 displayed thereon, FIG. 16(b) illustrates an option setting screen D250 which is output to the output part 110, upon selection of the shortcut option D209, and FIG. 16(c) illustrates a course selection screen D20 after a setting value of the shortcut option D209 is set on the option setting screen D250.

As described above, the shortcut option D209 may be displayed as an object selectable by the user. Upon selection of the shortcut option D209 on the course selection screen D20, the output part 110 may display the option setting screen D250 on which a plurality of option values D251 for the shortcut option D209 are displayed to be selectable.

Each of a plurality of options may have a plurality of option value D251. For example, a rinse number option may have option values D251 such as ‘1 time’ and ‘2 times’. The controller 70 may pre-store a plurality of option values D251 for each of the plurality of options.

For each of the plurality of options, one option value D251 may be stored in the controller 70 as a setting value corresponding to a setting result for the option. For example, when the option value D251 corresponding to ‘2 times’ is selected as the setting value of the rinse number option from among the plurality of option values D251, the controller 70 may store the setting value of the rinse number option as 2 times, and when performing a treatment course, perform a rinse cycle twice.

The output part 110 may output the option setting screen D250 on which a plurality of option values D251 for an option are displayed as selectable objects. The option setting screen D250, which is displayed upon selection of the shortcut option D209 on the course selection screen D20, may display a plurality of option values D251 for the shortcut option D209.

Each of the plurality of options may have an initial setting value before the user adjusts it. The initial setting value may be predetermined or adjusted by the controller 70. The initial setting value may be one of the plurality of option values D251.

The shortcut option D209 may be displayed to indicate the setting value on the course selection screen D20. The user may easily identify the setting of the shortcut option D209 directly on the course selection screen D20. Before the user changes the setting, the shortcut option D209 may be displayed to indicate the initial setting on the course selection screen D20. FIG. 16(a) shows a shortcut option D209 indicating an option value D251 of ‘35 minutes’ as an initial setting value.

Upon selection of the shortcut option D209 on the course selection screen D20, the controller 70 may control the output part 110 to output the option setting screen D250. An option value D251 corresponding to a current setting value D252 and the other option values D251 may be displayed distinguishably from each other on the option setting screen D250. In FIG. 16(b), the option value D251 corresponding to the current setting value D252 is shown with higher brightness than the other option values D251, to which the disclosure is not necessarily limited.

When the setting value of the shortcut option D209 is changed from a first option value D251 to a second option value D251 through the option setting screen D250, the shortcut option D209 may be displayed to indicate the second option value D251 as the setting value.

That is, the shortcut option D209 may be displayed to indicate the current setting value on the course selection screen D20. Therefore, when the first option value D251 of the plurality of option values D251 is the setting value, the shortcut option D209 may be displayed to indicate the first option value D251. When the setting value is changed from the first option value D251 to the second option value D251, the shortcut option D209 may be displayed to indicate the second option value D251.

In FIG. 16(c), upon selection of an option value D251 of ‘55 minutes’ on the option setting screen D250 of FIG. 16b, the shortcut option D209 indicates 55 minutes on the course selection screen D20.

FIG. 17 illustrates an option display screen D200 and a course progress screen D30 output from a course selection screen D20 according to an embodiment of the disclosure. FIG. 17(a) illustrates a course selection screen D20 on which a shortcut course CS is displayed as a target treatment course D120, FIG. 17(b) illustrates an option display screen D200 for the shortcut course CS, and FIG. 17(c) illustrates a course progress screen D30 for the shortcut course CS.

In an embodiment of the disclosure, upon selection of one of a plurality of treatment courses on the course selection screen D20, the output part 110 may output the option display screen D200 which displays at least some of a plurality of options for the selected treatment course.

Herein, the selection refers to an input signal different from an input signal that commands execution of a corresponding treatment course through manipulation of the start/pause button 140 or the like. For example, upon selection of the target treatment course D120 through the input part 120, the option display screen D200 for the target treatment course D120 may be displayed.

In an embodiment of the disclosure, upon receipt of a user touch signal on the course object D103 representing the target treatment course D120, the controller 70 may control the output part 110 to output the option display screen D200.

The option display screen D200 may display options for the target treatment course D120. On the option display screen D200, all of a plurality of options for the treatment course may be displayed at the same time, only some of them may be displayed in a switching relationship with the others, or only some of the options may be displayed at all times.

The options may be displayed to indicate their respective setting values on the option display screen D200. As the user selects the course object D103 on the course selection screen D20, the option display screen D200 may be output and the user may easily identify the setting values of the plurality of options.

However, in an embodiment of the disclosure, a shortcut option D209 may be identified directly on the course selection screen D20 without being output on the option display screen D200, thereby improving use convenience.

Further, only the shortcut option D209 among the plurality of options may be displayed on the course selection screen D20, which does not display the options displayed on the option display screen D200. That is, only the shortcut option D209 may be displayed on the course selection screen D20, excluding the plurality of options.

Accordingly, a plurality of treatment courses and information about the shortcut option D209 may be efficiently displayed without the deterioration of user visibility, which is caused by providing too much information in a limited output area of the output part 110.

As illustrated in FIG. 17(b), at least some of the plurality of options and the shortcut option D209 may be displayed together on the option display screen D200. That is, the shortcut option D209 may be displayed not only on the course selection screen D20 but also on the option display screen D200.

Accordingly, an embodiment of the disclosure may avoid an uncomfortable situation in which information about or the setting of the shortcut option D209 is available only on the course selection screen D20, not on the option display screen D200.

In other words, some of the options displayed on the option display screen D200 may also be displayed as selectable on the course selection screen D20. Some of the options may mean the shortcut option D209.

The shortcut option D209 may be displayed separately from the at least some of the plurality of options on the option display screen D200. That is, the shortcut option D209 may be displayed separately from other options in terms of position or concept on the option display screen D200. Among the options displayed on the option display screen D200, options other than the shortcut option D209 are referred to as general options D208.

The option display screen D200 may include an option display area D201 in which the general options D208 are displayed, and the shortcut option D209 may be displayed outside the option display area D201.

In an embodiment of the disclosure, the above-described course object D103 may be displayed on the option display screen D200, and the shortcut option D209 may be displayed located inside the border portion D109 of the course object D103, so that it may be distinguished from the other options in terms of position.

Each of the options displayed on the option display screen D200 may be displayed to be selectable through the input part 120. Upon selection of one of the plurality of general options D208 on the option display screen D200, the output part 110 may output the afore-described option setting screen D250 for the selected general option D208.

Referring to FIG. 17(c), in an embodiment of the disclosure, when the start/pause button 140 is manipulated on the course selection screen D20, the target treatment course D120 may start.

Further, upon selection of the target treatment course D120 on the course selection screen D20 through the input part 120, the option display screen D200 for the target treatment course D120 may be output, as described above.

As described above, in an embodiment of the disclosure, the user may conveniently command execution of a plurality of processes on the course selection screen D20, such as outputting the option display screen D200 or executing a treatment course.

FIG. 18 illustrates an option display screen D200 for a general course and an option display screen D200 for a shortcut course CS. The general course may be defined as a treatment course other than a shortcut course CS among a plurality of treatment courses.

FIG. 18(a) illustrates the option display screen D200 for the general course, on which a plurality of options are all displayed in a selectable state T1, and FIG. 18(b) illustrates the option display screen D200 for the shortcut course CS, on which some of a plurality of options are displayed in the selectable state T1, and the other options are displayed in an unselectable state T2.

In an embodiment of the disclosure, some of the options displayed on the option display screen D200 may be displayed in the selectable state T1 in which they may be selected through the input part 120, and the other options may be displayed in the unselectable state T2 in which they are not selectable.

The selectable state T1 refers to a state in which the setting value of a corresponding option may be changed and thus the option setting screen D250 may be output, and the unselectable state T2 refers to a state in which the user is not allowed to arbitrarily change the setting value, and thus the option setting screen D250 may not be output.

The option display screen D200 for the shortcut course CS displays some of the options in the unselectable state T2.

The number of options displayed in the selectable state T1 on the option display screen D200 for the shortcut course CS may be smaller than the number of options displayed in the selectable state T1 on the option display screen D200 for the general course.

For example, some of the options displayed in the selectable state T1 on the option display screen D200 for the general course may be displayed in the unselectable state T2 on the option display screen D200 for the shortcut course CS.

For example, when adjustment of the shortcut option D209 involves adjustment of other options, when adjustment of the shortcut option D209 takes precedence over adjustment of other options, or when adjustment of other options is meaningless due to the occurrence of the shortcut option D209, the user may not be allowed to adjust at least one option in relation to the shortcut option D209.

In this case, some options may be displayed in the unselectable state T2 on the option display screen D200 for the shortcut course CS on which the shortcut option D209 exists. The setting values of the options in the unselectable state T2 may be dependent on a change in the setting value of the shortcut option D209 or may be kept constant.

For example, in an embodiment of the disclosure, the shortcut option D209 may correspond to a required time option for setting a required time for any one of the plurality of treatment courses.

In order to adjust a required time for a treatment course, the number of times at least one cycle belonging to the treatment course is performed or an execution time of the at least one cycle needs to be adjusted dependently, and thus, the number option for the cycle may be configured not to be adjusted by the user in the controller 70.

For example, referring to FIG. 18(b), the shortcut course CS may correspond to a wash course for performing a process of washing laundry. In this case, the required time option for adjusting a required time for the wash course may be provided to the user as the shortcut option D209.

In this case, when the time required for the wash course is adjusted, the afore-described rinse number and so on needs to be adjusted dependently. Accordingly, the controller 70 may change the setting value of the rinse number option based on a change in the setting value of the required time option, and configure the rinse number option not to be changed by the user.

The wash course with the required time option as described above may be referred to as a time wash course in an embodiment of the disclosure. However, an embodiment of the disclosure is not necessarily limited to the wash course and the corresponding required time option, and may also be applied to various treatment courses and various options, such as a dry course.

FIG. 19 illustrates a process of determining an initial setting value of a shortcut option D209 according to an embodiment of the disclosure. FIG. 19(a) illustrates a course selection screen D20 displaying a close recommendation message D310 that recommends to close the door 19, FIG. 19(b) illustrates a course selection screen D20 displaying a laundry amount detection message D320 indicating that the amount of laundry is detected, and FIG. 19(c) illustrates a course selection screen D20 displaying a shortcut option D209.

In an embodiment of the disclosure, the initial setting value of the shortcut option D209 before being changed through the option setting screen D250 may be changed according to a treatment condition for laundry. That is, the initial setting value of the shortcut option D209 may be changed depending on the treatment condition for the laundry. The treatment condition may vary, including a laundry amount, a laundry material, a treatment time, a season, and weather.

As described above, in an embodiment of the disclosure, the shortcut option D209 may correspond to a required time option for setting a required time for any one of the plurality of treatment courses.

Further, the treatment condition may include the amount of laundry accommodated in the drum 13, and the initial setting value may be changed depending on the laundry amount. That is, the controller 70 may determine the initial setting value based on the laundry amount.

Specifically, the required time option is an option that determines a time required for a treatment course, and a required time range may be determined depending on the amount of laundry required to be treated, that is, the laundry amount.

For example, when too short a time is set for too much laundry, the laundry may not be sufficiently washed. Additionally, when too a long time is set for too small an amount of laundry, water, detergent, time, and so on may be unnecessarily wasted.

Accordingly, in an embodiment of the disclosure, the setting value of the shortcut option D209 may be determined in an appropriate setting range by presenting the initial setting value of the shortcut option D209 to the user based on the amount of the laundry.

In an embodiment of the disclosure, the controller 70 may determine the initial setting value by determining the amount of the laundry before performing one of the plurality of treatment courses.

When the shortcut option D209 corresponds to a required time option, the required time option may be set before the treatment course is performed, and in an embodiment of the disclosure, the controller 70 may determine the amount of the laundry in the course selection process P2, so that the initial setting value of the required time option is determined based on the amount of the laundry.

Further, in an embodiment of the disclosure, the amount of laundry may be determined in various manners. For example, the controller 70 may determine the amount of laundry, based on a detection result of a load sensor provided in the drum 13 or by measuring a current or voltage value of the driving part 14, while controlling the driving part 14 to rotate the drum 13.

Further, in an embodiment of the disclosure, the controller 70 may determine the amount of laundry at various times or under various conditions. For example, the controller 70 may perform a laundry amount determination process in the start process P1 performed upon power-on, or at a time when the shortcut course CS is displayed as the target treatment course D120.

In an embodiment of the disclosure, laundry may be input into or discharged from the drum 13 through the laundry inlet 18, when the afore-described door 19 is open. In other words, it may be understood that the door 19 is open before the amount of laundry is determined.

Therefore, in an embodiment of the disclosure, when the laundry inlet 18 is switched from the open state to the closed state by the door 19, the controller 70 may perform the process of determining the amount of laundry.

In this case, when the laundry inlet 18 is in the open state with the course selection screen D20 output, the output part 110 may output the close recommendation message D310 recommending to close the laundry inlet 18.

That is, upon selection of a shortcut course CS, which has a shortcut option D209 with an initial setting value determined based on the amount of laundry, such as the required time option, as the target treatment course D120, the controller 70 may recommend the user to rotate the door to the closed state by the close recommendation message D310, so as to confirm the amount of laundry.

The close recommendation message D310 may be output only in the open state of the door 19 or each time the shortcut course CS is selected as the target treatment course D120. That is, the controller 70 may propose to perform the laundry amount determination process by rotating the door 19 back to the closed state whenever the shortcut course CS becomes the target treatment course D120, in order to ensure accuracy of the laundry amount.

The close recommendation message D310 may include various phrases or shapes. In FIG. 19(a), a close recommendation message D310 including the phrase ‘Close the door and select a washing time’ is displayed, to which the disclosure is not necessarily limited.

In an embodiment of the disclosure, when the laundry amount determination process is being performed with the course selection screen D20 output, the output part 110 may output the laundry amount detection message D320.

The user may recognize that the laundry amount determination process is in progress by the laundry amount detection message D320. The laundry amount detection message D320 may have the effect of preventing the user from opening the door 19.

When the laundry amount determination process is completed along with the output of the laundry amount detection message D320 as described above, the controller 70 may control the output part 110 to display the shortcut option D209. That is, the shortcut option D209 may be displayed on the course selection screen D20, after the laundry amount determination process is completed by the controller 70.

As is apparent from the foregoing description, embodiments of the disclosure may provide a laundry treatment apparatus which enables setting of an option for a laundry treatment course on a screen output from an output part.

Further, embodiments of the disclosure may provide a laundry treatment apparatus for effectively shortening an option setting process.

Further, embodiments of the disclosure may provide a laundry treatment apparatus for displaying some of a plurality of options to be distinguishable from the remaining options and enabling the options to be adjusted conveniently.

Further, embodiments of the disclosure may provide a laundry treatment apparatus for effectively improving the visibility of a specific option and accessibility to the specific option, for settings.

Further, embodiments of the disclosure may provide a laundry treatment apparatus for notifying a user of a time required for a treatment course according to a laundry amount even before performing the treatment course.

Further, embodiments of the disclosure may provide a laundry treatment apparatus for enabling a user to conveniently adjust a required time for a laundry treatment course.

While the disclosure has been shown and described with respect to specific embodiments, it will be apparent to those skilled in the art that various modifications and variations may be made to the disclosure without departing from the scope and spirit of the disclosure as provided by the following claims.
