(95) FIG. 5 illustrates the display unit 200 of the laundry treating apparatus in accordance with the present disclosure.

(96) The display unit 200 may be formed in any shapes only if capable of displaying current states of the first and second treating units 110 and 120 or allowing the user to input operation commands of the first and second treating units 110 and 120.

(97) In FIG. 5, the display unit 200 is provided in a circular shape.

(98) The display unit 200 may be a touch panel so as to receive the operation command by enabling the overall region to sense an external force or electricity of the surface.

(99) The display unit 200 may include a first region 210 and a second region 220 which are distinguished from each other.

(100) Both of the first and second regions 210 and 220 are capable of displaying screens and sensing the external force or electricity to receive the operation command.

(101) The first and second regions 210 and 220 may be provided by dividing the display unit 200 (see FIG. 5 (a)) or a predetermined region of the display unit 200 is formed as the first region 210 and another region distant from the first region is formed as the second region 220 (see FIG. 5 (b)).

(102) Meanwhile, different from what is shown in the drawings, the first region 210 and the second region 220 may be provided side by side.

(103) The display unit 200 may display a screen on the full region so that the first region 210 and the second region 220 can selectively display a screen based on a specific control signal.

(104) The display unit 200 may further include a third region 230 provided as the integration of the first and second regions 210 and 220.

(105) The third region 230 may occupy the full screen of the display unit 200. When the first region 210 and the second region 220 are formed in some region of the display unit 200, the third region 230 may be overlapped with the first and second regions 210 and 220.

(106) Accordingly, the display unit 200 may display the current states of the first and second treating units and screens related with the first and second treating units so as to receive operation commands configured to wash or dry clothes in the first and second treating units.

(107) The currents states of the first and second treating units mean a state where the first and the second treating units 110 and 120 are linked to the control unit 300 or the display unit 200. The screen capable of receiving the operation commands mean the courses for performing washing or drying cycles in the first and second treating units 110 and 120.

(108) Hereinafter, it is described that the display unit 200 displays screens related with the first and second while describing a control method of the laundry treating apparatus.

(109) FIG. 6 illustrates a control method for controlling the first and second treating units 110 and 120 by using one display unit 200. FIGS. 7 through 13 illustrate screens displayed on the display unit 200 in steps of the control method.

(110) When the power is supplied to the display unit 200, the control unit 300 is implemented to perform a sense step (S1) for sensing whether the first treating unit 110 and the second treating unit 120 are activated on the display unit 200. The sense step (S1) may be implemented to display an operation preparing state S100 of the laundry treating apparatus on the display unit 200 such as booting or loading (see FIG. 7).

(111) Because of that, the user might fail to recognize that the sense step (S1) is implemented.

(112) The state where the first and second treating units 110 and 120 are activated may mean a state where the first and second treating units 110 and 120 are ready to receive and perform an operation command from the display unit 200 or the control unit 300.

(113) In addition, the state where the units 110 and 120 are activated may mean a state where they are linked to the display unit and ready to transmit their current states to the display unit 200.

(114) For example, when the first power supply unit 118 is input to the first treating unit 110 or the second power supply unit 128 is input to the second treating unit 120, it is determined that the first or second treating unit 110 or 120 is activated.

(115) Once the sense step (S1) senses that both of the first and second treating units 110 and 120 are activated, a selection request step (S2) for displaying select information S200 for allowing the user to select the first and second treating units 110 and 120 on the display unit 200 may be performed.

(116) Specifically, the select request step (S2) is implemented to allow the user to select the unit to control or operate. The select information S200 may mean that names of the activated treating unit are displayed on the display unit 200 (for example, the first treating unit and the second treating unit).

(117) In other words, the select request step (S2) means that the treating unit the user selects to control or operate is specified.

(118) At this time, the select information S200 may include a first select information s210 for selecting the first treating unit 110; and second select information s220 for selecting the second treating unit 120 (see FIG. 8 (a)).

(119) When it is sensed in the sense step (S1) that both of the first and second treating units and 110 and 120 are activated, the select request step (S2) may display the first select information S210 in the first region 210 and the second select information S220 in the second region 220 distinguishably.

(120) In this instance, the display unit 200 is divided into top and bottom regions as the first and second regions 210 and 220. The first select information S210 is displayed on the first region 210 and the second select information S220 is displayed on the second region 220 (see FIG. 8 (a)).

(121) Alternatively, the display unit 200 may be divided into left and right regions as the first and second regions 210 and 220. The first select information and the second select information may be displayed in the first region 210 and the second region 220, respectively.

(122) However, in case the first and second treating units 110 and 120 are arranged in top and bottom portions, the right and left displaying might confuse the user and it is preferred that the display unit 200 is divided into upper and lower regions.

(123) Meanwhile, once the sense step (S1) senses that one of the first and second treating units 110 and 120 is activated, the select request step (S2) may display only the select information S200 of the activated treating unit on the third region 230. At this time, the select information may be the first select information S210 or the second select information S220 (see FIGS. 8 (b) and (c)).

(124) For example, only the select information S210, S220 of the activated treating unit may be displayed on the full region of the display unit 200 (for example, names).

(125) Accordingly, the user is able to check the activated treating unit and avoid loading clothes in the wrong unit.

(126) In the select request step (S2), the user is able to select the select information S200 by pressing the display unit 200. For example, the user may select the select information S200 by pressing the first region 210 and the second region 220 (see FIG. 9).

(127) In this instance, when trying to select the first and second regions 210 and 220 simultaneously, the user may press the first and second regions 210 and 220 simultaneously in a preset time period or press a OK button (not shown) after pressing the first and second regions 210 and 220.

(128) A course select step (S3) may be implemented to display specific contents of an operation command which is performed in the selected one of the first and second treating units 110 and 120.

(129) Once both the first select information S210 and the second select information S220 are selected in the select request step (S2), the course display step (S3) may display an operation command S310 which is performable in the first treating unit 110 in the first region 210 and an operation command S320 which is performable in the second treating unit 120 in the second region 220 (see FIG. 10 (a)).

(130) Accordingly, the user is able to input the operation command S310 implemented in the first treating unit and the operation command S320 implemented in the second treating unit separately.

(131) When the first select information S210 or the second select information S220 is selected in the select request step (S2), an operation command S300 performable in the selected treating unit may be displayed in the third region 230 combined with the first and second regions 210 and 220 (see FIG. 10 (b)).

(132) At this time, that the first select information S210 or the second select information S220 is selected in the select request step (S2) may include a case that only one select information is selected even when both of the treating units are activated and a case that the select information of the activated treating unit is selected after the first treating unit or the second treating unit is activated.

(133) Accordingly, the user is able to input the intended operation command to the selected treating unit appropriately.

(134) Meanwhile, when both the first select information s210 and the second select information s220 are selected, the course display step (S3) displays operation commands S310 performable in one of the treating units 110 and 120 in the third region 230. After that, the user selects the operation command performable in the one of the treating units and then the course display step (S3) displays operation commands (S320) performable in the other treating unit in the third region 230 sequentially (see FIG. 10 (c)).

(135) In this instance, when desiring to input the operation command S300 to one of the treating units which is not displayed on the third region 230 first, the user may apply a slide force from the first region 210 to the second region 220 of the display unit 200.

(136) Specifically, even though both of the first and second treating units 110 and 120 are selected, contents of the operation commands S300 performable in the treating units are displayed on the display unit 200 sequentially and the user is then able to input the operation commands (S300) without errors.

(137) Meanwhile, once only one of the first select information S210 and the second select information S220 is selected in the select request step (S2), the course display step (S3 may display only the contents of the operation commands S300 performable in the selected treating unit in the third region 230 combined with the first region 210 and the second region 220.

(138) The operation commands S300 may be specific commands for performing at least one of washing and drying cycles in the first and second treating units 110 and 120.

(139) More specifically, the operation commands may include a normal course S330 configured of a course performing one or more of a wash cycle configured to removing foreign substances from clothes, a rinse cycle configured to rinse clothes and a dry cycle configured to dry clothes; and a special course S340 configured of an allergy care cycle configured to keep clothes over a preset specific temperature for a preset time period, a stain-remove cycle configured to remove stains from clothes by increasing the repetition number, duration time and cycle temperature of the preset washing and rinsing cycles.

(140) The normal course (330) may be configured of a normal course S331; a speed wash course S332; a heavy duty course S333; a wool course S334; and a perm press course S335, in case the first treating unit 110 is and the second treating unit 120 are provided as washers. The courses may be displayed on the display unit 200 as icons (see FIG. 10 (d)).

(141) The normal course S331 may mean the course configured to perform washing at an average water level, an average duration time, an average water temperature and an average RPM of all the courses or cycles performed in the first or second treating units 110 or 120.

(142) The speed wash course S332 may mean a shortened course with a shorter duration time than the normal course.

(143) The heavy duty course S333 may mean a course for washing relatively heavier clothes than the normal course, with an increased water amount or an increased RPM compared with the average water amount and RPM of the normal course.

(144) The wool course S334 may mean a course configured to perform washing with a lowered water amount and a lowered RPM compared with the average water amount and RPM of the normal course.

(145) The perm press course S335 may mean a course configured to press wrinkles by rotating the drum additionally after ending the spinning cycle.

(146) The special course S340 may be configured of an allergy care course S341; a stain care course S342; a delicate course S343; an outdoor course S344; and a direct wear course S345. The courses may be displayed on the display unit 200 as icons (see FIG. 10 (d)).

(147) The outdoor course S343 may mean a course in which the drum is rotated at a higher RPM than the normal course.

(148) The direct wear course S345 may mean a course configured to perform the dry cycle after the wash cycle and then prevent wrinkles by rotating the drum for a preset time period.

(149) The normal course S330 and the special course S340 operated in the selected treating unit after displayed in the course display step (S3) may be displayed in the first region 210 and the second region 220, respectively.

(150) However, if there are many specific courses are provided in the normal course S330 and the special course S340 and displayed in the first region 210 and the second region 220, respectively, the user might fail to recognize each of the courses clearly.

(151) The course display step (S3) may display specific contents or icons of the normal course S330 in the third region 230 of the display unit 200. When an external force for sliding the display unit 200 vertically or horizontally is applied, it is preferred that specific contents or icons of the special course S340 are displayed in the third region 230 (see FIG. 10 (d)).

(152) More specifically, when both the first select information and the second select information are selected in the select request step (S2), the course display step (S3) may display first the operation commands S300 performable in one of the first and second treating units 110 and 120 in the third region 230. Hence, when the selection of the operation commands S300 performable in the first treating unit 110 is complete, the course display step (S3) may display operation commands S300 performable in the other treating unit in the third region later.

(153) At this time, when the operation commands S300 performable in one of the first and second treating units 110 and 120 first, the normal course S330 is displayed first. After that, when the slide external force is applied to the display unit 200, the special course S340 may be displayed later.

(154) Meanwhile, the first select information S210 or the second select information S220 may be selected in the select request step (S2), which may include a case of displaying only the selected information of one treating unit in the select request step (S2) after one of the treating units is activated in the sense step (S1) as mentioned above. The course display step (S2) may display only the operation commands performable in the selected treating unit. At this time, the course display step (S2) may display contents of the normal course S330 and contents of the special course S340 in the first region 210 and the second region 220, respectively. Alternatively, one of the normal and special courses S330 and S340 may be displayed in the third region 230 and the other course may be displayed when the external force for sliding is applied.

(155) The control method of the laundry treating apparatus in accordance with the present disclosure may further include a course input sense step (S4) for sensing whether operation commands of the selected treating unit in the course display step (S3) is input.

(156) More specifically, when both the first select information and the second select information are selected in the select request step (S2), the control unit 300 in the course input sense step (S4) may sense whether the operation commands S300 performable in the first treating unit and the operation commands performable in the second treating unit are input in the course display step (S3).

(157) When the first select information or the second select information is selected in the select request step (S2), the control unit 300 in the course input sense step (S4) may sense whether the operation commands S300 performable in the selected treating unit are input.

(158) Unless the operation commands S300 performable in the selected treating unit are input in the course input sense step (S4), the current step returns to the course display step (S3) to induce the user to input the operation command to the selected treating unit.

(159) At this time, the current state may be in standby until the user inputs the operation command or display alarm information for inducing input to the display unit 200.

(160) Meanwhile, even when selecting one of the normal and special courses S330 and S340, the user is likely to intend to perform a specified course in the selected treating unit.

(161) For example, the user is likely to wash or dry specific clothes over or below a preset temperature or strengthen a soaking function for clothes. That is, the user intends to change the contents set in each course to perform a wash or dry cycle for specific clothes.

(162) To reflect those cases, once the operation commands are input in the course display step (S3), a setting change step (S5) may be performed to change one of setting information S500 which includes laundry amount and/or contamination levels S510, temperature S520, drum RPM S540 and rinsing number S530 (see FIG. 11).

(163) The setting change step (S5) is implemented to change one or more of the setting information S500 set in the normal course S330 and the special course S340, to be fitted to the user's intension.

(164) In the setting change step (S5), the setting information S500 is dividedly displayed on the display unit 200. When the divided region is pressed, one or more of changeable setting information 500 may be displayed. One of the displayed changeable setting information S500 is selected and then the setting information is changed into the selected setting information (see FIG. 11).

(165) Accordingly, a personalized wash or dry cycle fitted to the user's intension may be performed.

(166) The user may not intend to change the setting in the setting change step (S5). In other words, the user may usually trust the setting information of the normal and special courses and not intend to change the setting information in the setting change step.

(167) At this time, the control flow of the laundry treating apparatus pauses without changing the setting information in the setting change step (S5), the performing of the operation commands S300 may be delayed.

(168) To prevent that, the preset operation command S300 may be performed in the selected treating unit as it is, unless any inputs are made in the setting change step (S5) for a preset time period.

(169) Once all of the steps mentioned above are completed, the selected treating unit may perform the input operation commands S300.

(170) A process display step (S6) configured to display a process state S600 of the operation command performed in the selected treating unit in the display unit 200 may be performed. The process display step (S6) may provide certain information including the laundry amount S610, the water temperature S620, the drum RPM S630 and the currently processing course S640.

(171) The process display step (S6) may display contents including the remaining time S650, the currently progressing cycle S660 and specific description of the course or cycle (see FIG. 12 (a)).

(172) Accordingly, the user is able to check whether the intended operation commands is performed in the selected treating unit and whether the selected treating unit is malfunctioned.

(173) Meanwhile, the control unit 300 may further perform an end determine step (S7) configured to determine whether the operation of the first treating unit 110 and the operation of the second treating unit 120 end, when the first and second treating units 110 and 1200 are ready to perform the operation commands simultaneously.

(174) In the end determine step (S7), the control unit may display only the processing state of the other one, when sensing that one of the first and second treating units 110 and 120 ends the performance of the operation command (see FIG. 12 (b)).

(175) In other words, only the operation state of the currently progressing treating unit may be displayed so that the user may be provided with only meaningful information.

(176) As mentioned above, the control unit 300 may provide the user with the display state information of the laundry treating apparatus including the first treating unit 110 and the second treating unit 120 on the display unit 300.

(177) Moreover, the control unit may control the laundry treating apparatus including the first treating unit 110 and the second treating unit 120 by allowing the user to manipulate the display unit 300.

(178) In this instance, the displaying order, input method and contents displayed on the display unit 200 may not be familiar to the user who uses the laundry treating apparatus for the first time.

(179) Accordingly, it is necessary to provide guidelines and explanation about the manipulation method of the display unit 200 to the user who is unfamiliar to the display unit 200.

(180) For that, when the power is supplied to the laundry treating apparatus, the control unit 300 may perform a guide step (S2-1) configured to display guidelines about the manipulation method of the display unit 200.

(181) The guide step (S2-1) may be performed before or after the sense step (S1). In other words, it is after the select request step (S2) that the user starts to manipulate the display unit 200, so that the guide step (S2-1) can be performed before the select request step (S2).

(182) In the guide step (S2-1), start, remove and no re-start of the guidelines to manipulate the display unit 200 and confirm of the start, remove and no re-start may be displayed on divided regions of the display unit 200.

(183) More specifically, icons implemented to display start S221, remove S222, no more of the display unit use guidelines and confirm of the no more guidelines S224 on divided regions of the display unit 200 (see FIG. 13).

(184) The user is able to touch the surface of the display unit 200 which displays icons for the start S221, the remove S222, the no re-start of the use guidelines and no more guidelines S223 and then touch the confirm icon.

(185) At the same time, when the guide step (S2-1) starts, a text message of “check washer usage guidelines” S225 on a center of the display unit 200.

(186) When the user selects the start of the use guidelines, a guideline describe step (S2-2) may be implemented to display specific use guidelines about the manipulation manual of the display unit 200.

(187) The guideline describe step (S2-2) may be configured of select request step (S2) and the course input step (S4) tutorial.

(188) When the user selects the remove of the use guideline, the guide step (S2-1) ends and the select request step (S2) is implemented.

(189) When the user selects the no re-start of the use guideline in the guide step (S2-1), the guide step (S2) may be omitted from the next power-ON.

(190) It is likely to start the guide step (S2) unintendedly or not to repeat the guide step (S2) when a confirm button is additionally displayed. Accordingly, the confirm button is displayed to check the user's intension.

(191) Various variations and modifications are possible in the component parts and/or arrangements of the subject combination arrangement within the scope of the disclosure, the drawings and the appended claims. In addition to variations and modifications in the component parts and/or arrangements, alternative uses will also be apparent to those skilled in the art.
