Description

Terminal device, home appliance, method for controlling a terminal device, and control system for a home appliance using a terminal device

[0001] The present invention relates to a terminal device, a home appliance, a control method of the terminal device, and a control system of the home appliance using the same, which changes a course according to a satisfaction evaluation of a course set in the home appliance.

[0002] Home appliances that operate according to set courses, such as dishwashers, washing machines, garment steamers (stylers), and cooking appliances, are widely used.

[0003] These devices can be operated so that when a course is set by a user, at least one administration is performed according to the set course.

[0004] The course set by the user may be changed by the user or by a pre-set program, and the home appliance may be operated according to the changed course.

[0005] For example, a washing machine or dishwasher can perform operations such as washing, rinsing, and drying. Users can set or change the courses for these operations.

[0006] As another example, a clothing processing device can operate to perform operations such as steaming, wrinkle removal, odor removal, and dust removal, and a cooking device can operate to perform operations such as heating, rotation, and cooling.

[0007] Other home appliances can also be operated to perform administration according to their respective functions.

[0008] However, with home appliances, a situation may arise where satisfaction with a set course is low after the operation is completed. In this case, the user needs to change the appliance's current course.

[0009] Conventional home appliances do not support a function to change courses based on course satisfaction evaluations, and since they do not display both the current course and the course to be changed when changing courses, it was difficult to compare and verify the before and after of the course change.

[0010] Meanwhile, Korean Published Patent No. 10-2021-0069421 discloses a dishwasher and a control method for a dishwasher that provide a course and a washing option, and Korean Published Patent No. 10-2007-0117677 discloses a washing machine cleaning method and a washing machine equipped with a washing tub cleaning course.

[0011] The present invention aims to provide a terminal device, a home appliance, a control method of the terminal device, and a control system of the home appliance using the terminal device, which allow a course to be changed according to a satisfaction evaluation after the operation of the home appliance.

[0012] The present invention aims to provide a terminal device, a home appliance, a method for controlling a terminal device, and a control system for a home appliance using a terminal device, which allows for comparison of the before and after of a course change by simultaneously displaying the current course and the course to be changed on one screen when changing the course.

[0013] The present invention aims to provide a terminal device, a home appliance, a method for controlling a terminal device, and a control system for a home appliance using a terminal device, which allows for manual course change so that the user can directly set the driving conditions of the desired course.

[0014] A terminal device according to an embodiment of the present invention can set and change the course of a home appliance. To this end, the terminal device receives course information of the home appliance from a user, sets the course information, and then transmits it to the home appliance so that the course information is downloaded to the home appliance.

[0015] The home appliance operates according to a set course and notifies the terminal device of the end of operation when the operation is completed. Accordingly, when the terminal device is notified of the end of the home appliance's operation, it can conduct a user satisfaction evaluation for the corresponding course.

[0016] Accordingly, the terminal device displays a user interface for evaluating user satisfaction on the screen, and when a satisfaction evaluation is input from the user, it can change the course according to the set program by reflecting the satisfaction evaluation.

[0017] For example, if the cleaning process in a given course is unsatisfactory, the operating conditions of the cleaning process are changed. This involves modifying the stages of the cleaning process to ensure satisfactory results.

[0018] At this time, the administrative stages should be changed one step at a time rather than abruptly. This is because if the administrative stages are changed two or more times, there is a problem with the energy consumption and time required changing abruptly.

[0019] The terminal device displays course information before and after the change on a single screen when the course is changed. This allows the user to quickly understand the effects of the course change at a glance.

[0020] The terminal device may also display the estimated energy consumption and estimated time required for a course change. Of course, the energy consumption and time required before and after the course change can be displayed together on a single screen.

[0021] Such a terminal device may include: a terminal display unit that displays course information of a home appliance; a terminal communication unit that receives notification of the end of operation of the dishwasher; and a terminal control unit that controls the terminal display unit to display a user interface for evaluating the satisfaction of the course when the end of operation is notified, determines whether to change the course based on the course satisfaction evaluation by the user, and controls the terminal display unit to display course information before and after the change together on one screen when the course is changed.

[0022] Satisfaction evaluation items may include items for washing, drying, and time, and each evaluation item may be evaluated on a 5-level scale of very dissatisfied, dissatisfied, average, satisfied, and very satisfied.

[0023] The terminal control unit changes the driving conditions of at least one stroke constituting the course when the course is changed. At this time, the stroke may include a washing stroke and a drying stroke.

[0024] In other words, the operating conditions of the washing and drying cycles are changed when the course is changed. At this time, the terminal control unit increases or decreases the washing and drying cycles by one step each when the course is changed.

[0025] The terminal control unit can control the terminal display unit to display information regarding the effects before and after the change when the course is changed. These effects may include the estimated power consumption and estimated time required according to the course before and after the change.

[0026] The terminal device transmits information about the changed course to the dishwasher. At this time, the terminal device may transmit it directly to the dishwasher, or the terminal device may transmit it to a server and request the server to transmit it to the dishwasher.

[0027] A home appliance according to an embodiment of the present invention can receive course information from an external device, such as a terminal device or a server, and display it on a display device.

[0028] To this end, the home appliance includes a device communication unit that communicates with an external device to receive course information, a device display unit that displays the course information, and a device control unit that controls the device display unit to display the course information when the course information is received from the device communication unit.

[0029] The device control unit controls the device display unit to display the course information before and after the change together on one screen when the course is changed.

[0030] The device control unit controls the device display unit to display information regarding the effects before and after the change when the course is changed.

[0031] The device control unit controls the device display unit to display the estimated power consumption and estimated time required according to the course before and after the change together on one screen.

[0032] A home appliance can display information identical to that displayed on a terminal device. In this case, the home appliance may receive and display the same information from the terminal device, or it may receive and display the same information from a server as that from the terminal device.

[0033] A control method for a terminal device according to an embodiment of the present invention comprises: a step of controlling the terminal display unit to display a user interface for evaluating the satisfaction of a course of the home appliance in a terminal device including a terminal display unit and a terminal communication unit when a notification of the termination of operation of the home appliance is received through the terminal communication unit; and a step of controlling the terminal display unit to display course information before and after the course change together on one screen when the satisfaction evaluation is completed by a user in the terminal control unit, by determining whether to change the course based on the satisfaction evaluation.

[0034] A home appliance control system according to an embodiment of the present invention comprises: a home appliance; and a terminal device including a terminal display unit and a terminal communication unit. When a notification of the end of operation of the home appliance is received, the terminal device displays a screen for evaluating the satisfaction of a course, determines a course change based on the satisfaction evaluation by a user, displays course information before and after the course change together on one screen when the course is changed, and transmits the changed course information to the home appliance.

[0035] Here, the home appliance receives the changed course information and can display the course information before and after the change together on one screen.

[0036] Home appliances can display the same information as that displayed on the terminal device.

[0037] The terminal device, home appliance, control method of the terminal device, and control system of the home appliance using the terminal device according to an embodiment of the present invention have the following effects.

[0038] According to the present invention, after an operation according to a course is completed, a satisfaction evaluation for the course is performed, and the course can be changed based on the satisfaction evaluation.

[0039] According to the present invention, when changing a course, the current course and the course to be changed are displayed simultaneously on one screen, allowing the user to compare the course before and after the change and change the course.

[0040] According to the present invention, since the course can be changed directly by manual means, the course can be changed simply and quickly.

[0041] According to the present invention, in the satisfaction evaluation, even if the result is very satisfied or very dissatisfied, only one step of change is possible, thereby preventing rapid changes in time and energy.

[0042] According to the present invention, satisfaction evaluations for specific actions can be performed at various points in time.

[0043] According to the present invention, the user can directly set / change the course, and the course setting / changing is performed simply by minimizing the options for selecting the course.

[0201] The washing process can be subdivided into a pre-washing process and a main washing process, and the rinsing process can be subdivided into a general rinsing process and a heat rinsing process.

[0202] The terminal display unit (240) may also display the operation conditions of the administration for the course to be changed when the course is changed.

[0203] At this time, the terminal display unit (240) can display the driving conditions for each administration before and after the course change on one screen.

[0204] The terminal display unit (240) can display the estimated power consumption and estimated time required when the dishwasher (10) operates according to the course under the control of the terminal control unit (250).

[0205] The terminal display unit (240) may be provided as a display panel of a previously disclosed type, or as a touchscreen formed integrally with the terminal input unit (210) as described above.

[0206] The terminal control unit (250) can control the overall operation of the terminal device (20).

[0207] The terminal control unit (250) may include at least one processor that executes a program necessary to control the operation of the terminal device (20) and the dishwasher (10).

[0208] The processor may include one or more of a central processing unit (CPU), an application processor, or a communication processor.

[0209] The terminal control unit (250) can execute a dedicated app stored in the terminal storage unit (220) according to a user operation command input through the terminal input unit (210).

[0210] The terminal control unit (250) can execute a dedicated app and transmit course information entered by the user to the dishwasher (10) through the terminal communication unit (230).

[0211] The terminal control unit (250) can execute a dedicated app and transmit operation commands for the dishwasher (10) to the dishwasher (10) through the terminal communication unit (230).

[0212] For example, the terminal control unit (250) can transmit on / off commands, course setting / change / update commands, and operation commands according to the course to the dishwasher (10).

[0213] The terminal control unit (250) can control the terminal display unit (240) to display information including information related to the dishwasher (10) according to the user's operation.

[0214] The terminal control unit (250) can control the terminal display unit (240) to display a user interface that evaluates the satisfaction of the course when the operation of the dishwasher (10) is finished.

[0215] The terminal control unit (250) can change the course based on the course satisfaction evaluation by the user. At this time, the change of the course may involve changing the driving conditions of multiple administrations that constitute the course.

[0216] The administration of the above course may include washing administration, rinsing administration, drying administration, etc.

[0217] The washing process can be subdivided, for example, into a washing process and a main washing process, and the rinsing process can be subdivided, for example, into a general rinsing process and a heat rinsing process.

[0218] When changing the course, the operating conditions can be changed by changing the steps of the washing, rinsing, and drying cycles. Each of these cycle steps can be divided into, for example, 1 to N steps.

[0219] In this embodiment, the driving conditions are changed by dividing them into, for example, 1 to 7 steps. Of course, these steps are examples, and the number of steps can be changed.

[0220] The closer to level 1, the more the driving conditions may change relatively weakly or slightly, and the closer to level 7, the more the driving conditions may change relatively strongly or significantly.

[0221] The terminal control unit (250) may change the course by user operation. That is, by changing the driving conditions of each stroke of the course by user input, the course can be changed to one that suits the user's preference.

[0222] In this specification, the course before modification may be referred to as the "current course" or "first course," and the course modified to suit the user's preferences may be referred to as the "user-customized course" or "second course."

[0223] To change the course, the terminal control unit (250) can control the terminal display unit (240) to display a user interface that can change multiple administrative driving conditions.

[0224] The user can change from the current course (first course) to the user-customized course (second course) by changing the driving conditions for each administration of the current course using the user interface displayed on the terminal display unit (240).

[0225] At this time, changing the driving conditions of the above-mentioned stroke may involve changing the intensity of the stroke. This intensity may be divided into multiple stages.

[0226] When the driving conditions of the washing and rinsing cycles are classified into stages 1 to N, if the washing and rinsing cycles are at stage 1, the spray intensity of the washing water is the weakest, and as the stages are increased by one, the spray intensity of the washing water can gradually become stronger. When the washing and rinsing cycles reach the maximum stage N, the washing water can be sprayed at maximum intensity.

[0227] To this end, if the driving conditions of the washing and rinsing cycles are changed from stage 1 to stage 2, the terminal control unit (250) can control the washing device (210) to spray the washing water more strongly than in stage 1, and conversely, if the conditions are changed from stage 2 to stage 1, the washing device (210) can control the washing water to spray it less weakly than in stage 2.

[0228] As another example, if the driving conditions of the drying process are changed from stage 1 to stage 2, the terminal control unit (2250) can control the drying device (220) so that the heater emits heat more strongly than stage 1, and conversely, if the conditions are changed from stage 2 to stage 1, the drying device (220) can control the heater so that heat is emitted less weakly than stage 2.

[0229] As another example, if the driving condition for noise is changed from stage 1 to stage 2, the terminal control unit (250) can control the noise device (not shown) to increase the noise decibel (dB) higher than stage 1, and conversely, if it is changed from stage 2 to stage 1, the noise device can control the noise decibel (dB) lower than stage 2.

[0230] The above noise device can generate noise and change the decibel (dB) of the noise.

[0231] The terminal control unit (250) can receive information on the end of operation of the dishwasher (10).

[0232] The terminal control unit (250) can control the terminal display unit (240) to display a user interface that can evaluate satisfaction with the current course when the end of operation of the dishwasher (10) is notified.

[0233] The items for the satisfaction evaluation may include items such as washing, drying, and time. However, the present embodiment is not limited thereto, and some items may be deleted from the three items above, or other items may be added.

[0234] Satisfaction evaluations can be conducted in various ways.

[0235] In this embodiment, it is set so that it can be evaluated in 5 stages, such as very dissatisfied, dissatisfied, average, satisfied, and very satisfied.

[0236] However, the present invention is not limited thereto and can be evaluated in other ways. For example, a simple three-stage evaluation of dissatisfaction, average, and satisfaction is possible, and a more simple two-stage evaluation of dissatisfaction and satisfaction is also possible.

[0237] When satisfaction is divided into 5 levels, it can be indicated to be rated as very dissatisfied, dissatisfied, average, satisfied, and very satisfied (see Fig. 12). For example, 1 star can be rated as very dissatisfied, 2 stars as dissatisfied, 3 stars as average, 4 stars as satisfied, and 5 stars as very satisfied.

[0238] In other embodiments, instead of a star shape, it may be displayed in the shape of a circle, square, triangle, etc., and in yet another embodiment, satisfaction may be evaluated by assigning evaluation scores by subdividing each evaluation item into 1 to N levels according to the degree between dissatisfaction and satisfaction.

[0239] When a satisfaction evaluation is input by the user, the terminal control unit (250) can change the current course to a course tailored to the user's preferences by changing the driving conditions for each administration of the current course according to the satisfaction evaluation.

[0240] At this time, in the case of a course change, the course change can be made only when the satisfaction evaluation of the current course is very unsatisfactory or unsatisfactory. That is, the terminal control unit (250) changes the course only when the current course is very unsatisfactory or unsatisfactory.

[0241] Here, changing the course may involve changing the driving conditions of the strokes constituting the course one step at a time. However, if the change is made two or more steps, a drastic change in the required time and energy may occur, so changes of two or more steps need to be avoided.

[0242] Accordingly, in this embodiment, after the operation of the dishwasher (10), a user evaluates the satisfaction regarding washing, drying, and time items, and if a specific item is evaluated as very unsatisfactory or unsatisfactory, the operating conditions for washing, drying, and noise are changed. At this time, the operating conditions are changed only one step at a time, thereby preventing abrupt changes in time and energy consumption.

[0243] The terminal control unit (250) can control the terminal display unit (240) to display the before and after of the change in the driving conditions of each administration on one screen.

[0244] Accordingly, the terminal device (20) displays the driving conditions of each stroke before and after the course change on one screen, so that the user can compare the before and after of the course change and quickly understand the cleaning effect according to the user-customized course that changes.

[0245] The terminal control unit (250) can request the server (30) to display the driving conditions of each stroke before and after the course change on the device display unit (150) of the dishwasher (10).

[0246] That is, the server (30) can transmit the driving conditions of each course before and after the course change to the dishwasher (10) in response to a request from the terminal device (20), and the dishwasher (10) can display this information on the device display unit (150).

[0247] In this way, the server (30) may also allow information displayed on the terminal device (20) at the request of the terminal device (20) to be displayed on the dishwasher (10).

[0248] Meanwhile, the noise level can also be changed when changing courses. In the case of noise, lower noise is generally preferred.

[0249] However, if the noise generated by the dishwasher (10) in the kitchen is too quiet, the user in the living room has the inconvenience of having to go directly to the kitchen to check whether the dishwasher (10) is operating normally and visually check whether the dishwasher (10) is operating.

[0250] Conversely, if the noise of the dishwasher (10) is too loud, it may interfere with reading or watching TV.

[0251] Accordingly, in this embodiment, the terminal device (20) sets and changes the decibel (dB) of the noise so that an appropriate amount of noise is generated in the dishwasher (10) as needed.

[0252] Noise can be set / changed in decibels (dB) in fixed units, or it can be set / changed in level units by dividing the decibels (dB) into multiple steps or levels.

[0253] The terminal control unit (250) can transmit a user-customized course, which has been changed based on a user satisfaction evaluation, to the dishwasher (10) through the terminal communication unit (230).

[0254] Accordingly, the dishwasher (10) can update the current course (first course) to a changed user-customized course (second course), and then perform washing operations according to the changed user-customized course (second course).

[0255] The terminal control unit (250) may also control the terminal display unit (240) to determine the estimated power consumption and estimated time required according to the changed second course and display them on the screen.

[0256] At this time, the terminal control unit (250) can control the terminal display unit (240) so that the estimated power consumption and estimated time required before and after the course change can be displayed simultaneously on one screen.

[0257] Accordingly, users can quickly check the estimated power consumption and estimated time required before and after the course change, and understand the effects of the course change.

[0258] When a course change is determined, the terminal control unit (250) may request the server (30) to transmit the estimated power consumption and estimated time according to the changed course to the dishwasher (10).

[0259] FIG. 6 is an internal configuration block diagram of a server according to an embodiment of the present invention.

[0260] Referring to FIG. 6, a server (30) according to an embodiment of the present invention may be configured to include a server communication unit (310), a server storage unit (320), and a server control unit (330).

[0261] The server communication unit (310) can communicate with the dishwasher (10) and the terminal device (20).

[0262] The server communication unit (310) can perform communication via wired or wireless methods.

[0263] The server communication unit (310) can transmit a file for a software upgrade to the dishwasher (10) in response to a software upgrade request from the terminal device (20) for the dishwasher (10). The dishwasher (10) can upgrade the software through the file.

[0264] The server storage unit (320) can store information, data, programs, etc. necessary for the operation of the server (30).

[0265] The server storage unit (320) can store information related to the dishwasher (10) and the terminal device (20).

[0266] The server storage unit (320) may be provided as volatile and / or non-volatile memory, or may be provided in the form of a database (DB).

[0267] The server storage unit (320) can store information related to software upgrades of the dishwasher (10). The upgrade-related information may include software data installed in the dishwasher (10), information related to the dishwasher (10), user-related information, etc.

[0268] The server control unit (330) can control the overall operation of the server (30).

[0269] The server control unit (330) can store information transmitted from the dishwasher (10) and the terminal device (20) in the server storage unit (320).

[0270] The server control unit (330) can process information according to requests transmitted from the dishwasher (10) and the terminal device (20) and reply to each.

[0271] The server control unit (330) can upload software data to upgrade the dishwasher (10) through the upgrade management webpage of the dishwasher (10).

[0272] The server control unit (330) can automatically download the uploaded software data to the dishwasher (10).

[0273] The server control unit (330) can check the status and operation status of the dishwasher (10).

[0274] The server control unit (330) can manage and operate the dishwasher (10) by checking the status information and operation information that the dishwasher (10) periodically transmits.

[0275] The server control unit (330) can calculate the energy consumption and time required for the dishwasher (10) when operating the dishwasher (10) according to the course information transmitted from the terminal device (20) through the server communication unit (310).

[0276] The server control unit (330) can transmit the calculated energy consumption and time required to the terminal device (20).

[0277] The server control unit (330) transmits course information to the dishwasher (10) in response to a request from the terminal device (20), thereby allowing the dishwasher (10) to download the corresponding course information and update the course information.

[0278] Accordingly, the dishwasher (10) may display the corresponding course information through the device display unit (150).

[0279] The server control unit (330) can provide a user interface for evaluating satisfaction with the current course to the terminal device (20) in response to a request from the terminal device (20).

[0280] A user interface for evaluating the satisfaction of such courses can be provided to a terminal device (20) after the operation of the dishwasher (10).

[0281] In this embodiment, the course satisfaction evaluation item may be at least one of washing, drying, and time items. In other embodiments, some of these three items may be deleted or other items may be added.

[0282] When the satisfaction evaluation result is transmitted from the terminal device (20), the server control unit (330) can transmit course change information based on the satisfaction evaluation result to the dishwasher (10).

[0283] Course change information may include a change in the driving conditions of at least one stroke constituting the course. For example, it may be information on the change in driving conditions of a washing stroke, a rinsing stroke, and a drying stroke.

[0284] Accordingly, the dishwasher (10) can subsequently operate based on the changed course.

[0285] FIG. 7 is a flowchart showing the sequence of operations according to the operation of a dishwasher according to an embodiment of the present invention.

[0286] Referring to FIG. 7, the dishwasher (10) according to the present invention can operate in the steps of a washing step (S11), a rinsing step (S12), and a drying step (S13).

[0287] At this time, although not shown in the drawing, the washing process (S11) can be subdivided into a pre-washing process and a main washing process and performed in sequence. The rinsing process (S12) can be subdivided into a general rinsing process and a heat rinsing process and performed in sequence.

[0288] When a user loads used dishes onto the racks (101, 102) of the dishwasher (10), food residue may remain on the dishes.

[0289] Therefore, to wash the dishes inside, the dishwasher (10) can perform a washing process (S11) as the first process.

[0290] The washing process may perform a pre-wash process first. During the pre-wash process, the detergent is not guided toward the lower side of the tub, allowing bulky food particles on the dishes to be removed first using only wash water without detergent.

[0291] Once the pre-washing process is completed, the main washing process can be performed. When the dishwasher (10) washes dishes using only washing water without detergent, the grease stains on the dishes are not washed well, so the dishes are cleaned thoroughly by removing grease stains through the main washing process using detergent.

[0292] When the washing process (S11) is finished, the dishwasher (10) can discharge the used washing water to the outside through the sump (106) and supply new washing water to perform the rinsing process (S12).

[0293] The rinsing process may first perform a general rinsing process. In the general rinsing process, washing water is sprayed to remove detergent and other residues from the dishes. Subsequently, in the heated rinsing process, high-temperature heated washing water is sprayed to rinse the dishes once again and simultaneously raise the surface temperature of the dishes so that moisture adhering to the surface of the dishes evaporates easily within a short period of time.

[0294] When the rinsing process (S12) is finished, the dishwasher (10) can dry the dishes by performing a drying process (S13).

[0295] In this way, the dishwasher (10) can sequentially perform washing, rinsing, and drying cycles according to the set course, thereby allowing the washing of dishes to proceed and be completed.

[0296] Hereinafter, with reference to the attached FIGS. 8 to 35, the process of controlling the operation of a dishwasher (30) in a terminal device (20) according to an embodiment of the present invention will be described in detail.

[0297] FIGS. 8 to 10 are drawings illustrating the process of initially downloading a course set in a terminal device (20) according to an embodiment of the present invention to a dishwasher (10).

[0298] FIG. 8 is an example of a screen showing course information through a dedicated app or terminal application (ThinQ App) for managing / operating a dishwasher (10) in a terminal device (20) according to an embodiment of the present invention.

[0299] The course information screen can display detailed course information, along with the estimated energy consumption (estimated power consumption) and estimated time required for the course.

[0300] For example, the course information may have the driving conditions and noise levels of multiple strokes, namely washing and drying strokes, determined as initial values. In the drawing, for example, washing is set to 2 stages, drying to 1 stage, and noise to 1.

[0301] The estimated energy consumption and estimated time are exemplified as the estimated power consumption and estimated time required for the dishwasher (10) when there are 2 washing stages, 1 drying stage, and 1 noise stage as described above, respectively as 0.9 kWh and 1 hour and 2 minutes.

[0302] The figures shown in the drawings are illustrative figures for the convenience of explanation, and it is obvious that these figures may vary depending on the model of the dishwasher (10). It is stated in advance that the same applies to subsequent drawings.

[0303] These courses may be modified under specific conditions. In this embodiment, the course may be modified if a user inputs a satisfaction evaluation of the course after the dishwasher (10) has been operated at least once according to the course.

[0304] To inform of these conditions, a notice saying "If you evaluate satisfaction after washing, you can wash with the optimal course" may be displayed on the screen of Fig. 8.

[0305] The terminal device (20) can apply a course to the dishwasher (10). To do this, when the user touches the 'Download menu to dishwasher' on the screen of FIG. 8, the terminal device (20) can transmit the corresponding course information to the dishwasher (10).

[0306] Accordingly, the dishwasher (10) can download course information received from the terminal device (20) and store it in the device storage unit (160). As a result, the dishwasher (10) operates according to the stored course information during subsequent operation.

[0307] Figure 9 illustrates an example of a screen that informs users that they can use a customized course after evaluating their satisfaction after washing.

[0308] Course information downloaded to the dishwasher (10) can be reconfirmed. When course information is touched in FIG. 9, the current course information downloaded and applied to the dishwasher (10) can be displayed as in FIG. 10.

[0309] Since the course information of FIG. 10 is the course information initially downloaded to the dishwasher (10) by the terminal device (20), the screen of FIG. 10 may be the same as the screen of FIG. 8.

[0310] Course information may be transmitted directly by the terminal device (20) to the dishwasher (10), or the server (20) may transmit it to the dishwasher (30) upon the request of the terminal device (20).

[0311] In this way, the terminal device (20) displays specific information about the course before and after the course change on one screen simultaneously when the course is changed, and it is important that such specific information about the course before and after the course change is also displayed on one screen simultaneously in the dishwasher (10).

[0312] FIG. 11 is an example diagram showing a course transmitted from a terminal device to a home appliance according to an embodiment of the present invention and then displayed on the screen.

[0313] Referring to FIG. 11, a dishwasher (10) according to an embodiment of the present invention can receive course information transmitted from a terminal device (20) or a server (30).

[0314] Afterward, the dishwasher (10) can display the course information received through the device display unit (150). Thus, the user can check the course information on the terminal device (20) and also check the course information on the dishwasher (10).

[0315] Meanwhile, the dishwasher (10) may display information identical to the information displayed on the terminal device (20). This may be possible by the terminal device (20) directly transmitting the information displayed on the terminal device (20) to the dishwasher (20), or by the server (30) transmitting information identical to the information displayed on the terminal device (20) to the dishwasher (10).

[0316] In the case of other home appliances, such as washing machines, course information can be displayed on a display device. Specifically, the operation and driving conditions corresponding to the course can be displayed.

[0317] FIGS. 12 to 17 are drawings illustrating the performance of a satisfaction evaluation and the change of course information based on the satisfaction evaluation in a terminal device according to an embodiment of the present invention.

[0318] The terminal device (20) can receive operation information of the dishwasher (10).

[0319] This operation information may include information such as whether the dishwasher (10) has started, is in operation, or has finished operation.

[0320] Operation information can be received directly by the terminal device (20) from the dishwasher (10), or the dishwasher (10) can transmit to the server (30) and the terminal device (20) can receive from the server (30).

[0321] When the terminal device (20) receives information on the end of operation of the dishwasher (10), it can display a user interface on the screen that guides the satisfaction evaluation (see FIG. 12).

[0322] FIG. 12 is an example of a screen that shows how to change to a customized course based on the satisfaction evaluation of the last course used in the dishwasher (10).

[0323] When you touch "Evaluate Satisfaction" in Fig. 12, a user interface for evaluating satisfaction with the course may be displayed as shown in Fig. 13.

[0324] Satisfaction evaluation items may include washing, drying, time, etc.

[0325] However, these items are merely examples, and only some of the three items mentioned above may be displayed, or additional items may be added.

[0326] FIG. 13 illustrates, as an example, a user interface that evaluates the satisfaction of a course on a 5-star scale. It has been previously mentioned that there may be various methods for evaluating satisfaction.

[0327] In this embodiment, for example, among the 5 star ratings, 1 point from the left may mean very dissatisfied, 2 points dissatisfied, 3 points average, 4 points satisfied, and 5 points very satisfied.

[0328] For example, if the user is dissatisfied with the washing process in the current course, they can rate the washing process as unsatisfactory by touching the washing item with 2 stars in Fig. 13. In this case, as shown in Fig. 14, the washing item may be shaded up to 2 stars.

[0329] The satisfaction evaluation for each item of washing, drying, and time can be reflected in the course change of the dishwasher (10) later. That is, if the satisfaction for each item in the course is 'very dissatisfied' or 'dissatisfied,' the course for that item can be changed by one step to increase the satisfaction.

[0330] This involves changing the driving conditions of the course administration one step at a time so that items that are very dissatisfied or dissatisfied can have a satisfaction level of at least average or higher (i.e., average, satisfied, or very satisfied).

[0331] In this embodiment, if the satisfaction evaluation is rated as 'average', 'satisfied', or 'very satisfied', no course change is made.

[0332] In other embodiments, the course may be set to change even when 'Normal' is selected.

[0333] In Fig. 14, when the completion button is touched after the satisfaction evaluation, the terminal device (20) can recognize that the satisfaction evaluation is completed.

[0334] When the completion of the satisfaction evaluation is recognized by touching the completion button, the terminal device (20) changes to a course that reflects the satisfaction evaluation results as shown in FIG. 15, and can display information before and after the course change on one screen.

[0335] In one example of FIG. 15, an example of course change reflecting the results of a satisfaction evaluation is illustrated. Specifically, the current stage and the stage to be changed of the washing process, the current stage and the stage to be changed of the drying process, and the current stage and the stage to be changed of the noise can be displayed together on one screen.

[0336] In addition, for the washing and drying cycles, the energy consumption and time required before and after the course change can be displayed respectively.

[0337] Users can check the energy consumption and time required before and after the course change, respectively, to verify the effects of switching to the customized course tailored to their preferences.

[0338] Information regarding the course before and after changes is displayed together on one screen for comparison. As shown in Fig. 15, the information before and after changes can be displayed in the form of a bar graph to allow for easy and quick visual comparison. Of course, this form is merely an example.

[0339] When the apply menu in Fig. 15 is touched, the terminal device (20) can transmit the changed course information to the dishwasher (10).

[0340] The dishwasher (10) can download the changed course information and update it in the device storage unit (160). Afterwards, the dishwasher (10) operates according to the changed course.

[0341] The terminal device (20) can display a guide to try operating on the changed course according to the course change (see FIG. 16), and can display the changed course information when the course information menu is touched to check the changed course information (see FIG. 17).

[0342] In Fig. 17, when a course is changed based on a satisfaction evaluation, the course information before and after the change is displayed together on one screen.

[0343] Specifically, by displaying the washing, drying, and noise levels before and after reflecting the satisfaction evaluation on a single screen, information before and after the course change can be compared. At this time, the estimated energy consumption and estimated time according to the changed course may also be displayed.

[0344] FIGS. 18 to 20 are drawings illustrating cases where there is substantially no change in the course in the satisfaction evaluation according to an embodiment of the present invention.

[0345] The user can perform a satisfaction evaluation by touching the star rating for each evaluation item in the user interface of Fig. 18.

[0346] In this case, if you select 'average', 'satisfied', or 'very satisfied' in the satisfaction evaluation, the course will not be changed. In other words, evaluating one of these three means that you are satisfied with the current course or have no complaints, so a change of course is not considered.

[0347] In the user interface of Fig. 18, if you select one of ‘Normal’, ‘Satisfied’, or ‘Very Satisfied’ for all items of washing, drying, and time and touch the complete button, a notice that there is no course change based on the satisfaction evaluation result may be displayed as in Fig. 19.

[0348] If 'very dissatisfied' or 'dissatisfied' is selected for at least one of these three items, the user interface of FIG. 19 will not be displayed, and the user interfaces of FIG. 16 and FIG. 17 described above will be displayed. That is, this is because if evaluated as very dissatisfied or dissatisfied, the course is changed to become satisfied or very satisfied.

[0349] The user interface of Fig. 19 can be displayed for a set period of time and then switched to the user interface of Fig. 20. As another example, touching the user interface of Fig. 19 can switch to the user interface of Fig. 20.

[0350] Since there is no course change in Fig. 20, information about the current course may be displayed. That is, the course information before the change may be displayed on the screen.

[0351] Here, if there is no course change, the course information before the change is displayed, and a message indicating the effect of the course change (see FIG. 23) can be optionally displayed.

[0352] In this case, if there is no course change, it may be displayed on the screen as follows.

[0353] In one embodiment, only the course information prior to the change may be displayed on a single screen.

[0354] In another embodiment, information about the course before the change or a message guiding options for changing the course or the effects of changing the course (see FIG. 23) may be displayed together on one screen.

[0355] In another embodiment, the course information prior to the change may be displayed on the first screen, and a message guiding options for changing the course or the effects of changing the course may be displayed on the second screen.

[0356] At this time, the second screen may appear as a pop-up screen on the first screen, or it may appear as a screen separate from the first screen. As described above, the first and second screens can each serve as user interfaces.

[0357] FIGS. 21 to 23 are drawings illustrating cases where satisfaction evaluation is not performed in a terminal device according to an embodiment of the present invention.

[0358] The user may not evaluate the satisfaction of the course on the terminal device (20).

[0359] Figure 21 illustrates, as an example, a user interface for evaluating satisfaction.

[0360] A menu to express the intention not to perform a satisfaction evaluation may be displayed here, and if the user touches the menu, the terminal device (20) may recognize that the satisfaction evaluation will not be performed. Alternatively, if the user touches the cancel menu, the terminal device (20) may recognize that the satisfaction evaluation will not be performed.

[0361] If you select the corresponding menu or touch the cancel menu, the satisfaction evaluation is not performed, so the course information is not changed and the current course information can be displayed (see FIG. 22).

[0362] Afterward, when the dishwasher (10) operates according to the current course and the terminal device (20) receives information that the dishwasher (10) has finished operating, a user interface guiding a satisfaction evaluation can be displayed as shown in FIG. 23. This may be the same user interface as in FIG. 12.

[0363] Meanwhile, the user may also directly set and change the course on the terminal device (20).

[0364] That is, as described above, in one embodiment, the course may be changed to a new course (second course) by reflecting the satisfaction evaluation after the satisfaction evaluation, but in another embodiment, the user may change the course directly on the terminal device (20).

[0365] FIGS. 24 to 29 are drawings illustrating an example of directly changing course information after a satisfaction evaluation in a terminal device according to an embodiment of the present invention.

[0366] When the satisfaction evaluation is completed by the user, the user-customized course information that has been changed to reflect the satisfaction evaluation can be displayed on the screen of the terminal device (20) (see FIG. 24).

[0367] When switching to a customized course, the course information before and after the change can be displayed together on a single screen. In other words, the operating conditions before and after the change regarding washing, drying, and noise are displayed on one screen for comparison. In addition, the estimated energy consumption and estimated time corresponding to the changed course may be displayed together or separately.

[0368] Looking at FIG. 24, the terminal device (20) may display a menu for performing course direct setting by the user's touch.

[0369] When the direct setting menu is touched, the terminal device (20) may be provided with a user interface that allows the user to directly change the driving conditions for each stroke of the current course by touching or selecting (see FIG. 25).

[0370] FIG. 25 illustrates an example of a user interface in the form of a slide bar that allows a terminal device (20) to change the driving conditions of each stroke for course change.

[0371] This user interface can provide a slide bar that can change the operating conditions of the washing process and a slide bar that can change the operating conditions of the drying process.

[0372] Additionally, the user interface may provide buttons for selecting the noise level. The buttons may be displayed as numerical values ​​representing the noise level.

[0373] In the button's numerical value, level 1 may mean a small noise of relatively low decibels, and level 2 may mean a loud noise of relatively high decibels.

[0374] Although only two levels are shown in the drawing, this is merely an example, and the number of levels can be varied depending on the user's settings.

[0375] Accordingly, the user can change the operating conditions of the washing and drying process by adjusting the position of the adjustment point of each slide bar through the terminal input unit (210), and can change the noise level by touching the button.

[0376] The above user interface for changing driving conditions in each stroke according to a course change is exemplary, and therefore the present invention is not limited to such examples. Any user interface capable of receiving user input for changing driving conditions in each stroke may be applied without limitation.

[0377] FIG. 25 illustrates an example in which the driving conditions of the washing stroke are changed from the current 3 stages to 6 stages, the driving conditions of the drying stroke are changed from the current 4 stages to 5 stages, and the driving conditions of the noise are changed from the current 2 stages to 1 stage.

[0378] When the driving conditions for each administration are changed in this way, the changed driving conditions are displayed as shown in FIG. 26, and the course change update, which was disabled in FIG. 25, can be switched to enabled.

[0379] When the course change update is touched in Fig. 26, the course is updated to a user-customized course reflecting the changed operating conditions, and the terminal device (20) can transmit the updated user-customized course to the dishwasher (10).

[0380] These user-customized courses may be transmitted directly from the terminal device (20) to the dishwasher (10), or may be transmitted from the server (10) to the dishwasher (20) at the request of the terminal device (20).

[0381] In addition, as the driving conditions for each stroke change when the course is changed, the energy consumption (power consumption) and time required before and after the course change can be displayed together.

[0382] When the course change update is completed and the save menu is touched, the terminal device (20) can store the information of the updated user-customized course internally, or the terminal device (20) can transmit the information of the updated user-customized course to the server (30) so that the server (30) can store it internally.

[0383] In another embodiment, when the course change update in FIG. 26 is touched, the updated user-customized course information is not transmitted from the terminal device (20) to the dishwasher (10), and may be set to be transmitted when the save menu is touched.

[0384] In this case as well, the updated user preference-tailored course information from the terminal device (20) may be transmitted directly to the dishwasher (10), or it may be transmitted from the server (10) to the dishwasher (20) at the request of the terminal device (20).

[0385] When the save menu is touched in FIG. 27, the driving conditions of each stroke before and after the course change can be displayed on the terminal device (20) as in FIG. 28.

[0386] In other words, the operating conditions of washing, drying, and noise before and after the course change can be displayed.

[0387] The estimated energy consumption and estimated time before and after the course change can also be displayed.

[0388] Afterwards, a notice may be displayed instructing to use the dishwasher (10) with the changed course (see FIG. 29).

[0389] FIG. 30 is a diagram illustrating an example of directly setting course information without satisfaction evaluation in a terminal device according to an embodiment of the present invention.

[0390] The terminal device (20) may allow the user to directly set / change the course without a satisfaction evaluation.

[0391] Since no satisfaction evaluation is performed, the course information is not changed and only the current course information can be displayed (see Fig. 30).

[0392] Looking at FIG. 30, the terminal device (20) may display a menu for performing course direct setting by the user's touch.

[0393] When the "Direct Course Setting" menu is touched, the subsequent process can be carried out in the same way as the process described in FIGS. 25 to 29 above.

[0394] Both FIG. 30 and FIG. 24 provide a user interface that allows the user to set the course directly, but they differ in that FIG. 24 allows the user to set or change the course directly after a satisfaction evaluation, whereas FIG. 30 allows the user to set or change the course directly without a satisfaction evaluation.

[0395] In this way, the terminal device (20) of the present invention can control the user to directly perform course changes not only when there is a satisfaction evaluation but also when there is no satisfaction evaluation. This is intended to allow the user to set a customized course of their choice at various times.

[0396] In the present embodiment, when describing FIGS. 8 to 30, the terminal device (20) may set / change the course and transmit it to the dishwasher (10). The terminal device (20) may directly transmit the course information to the dishwasher (10), but preferably, the server (30) may transmit the course information to the dishwasher (10) at the request of the terminal device (20).

[0397] That is, in the latter case, the terminal device (20) requests the server (30) to transmit course information to the dishwasher (10), and the server (30) transmits the corresponding course information to the dishwasher (10) in response to this request.

[0398] FIG. 31 is a flowchart illustrating a change of course according to a satisfaction evaluation in a terminal device according to an embodiment of the present invention.

[0399] The terminal device (20) can set course information to be applied to the dishwasher (10) by running a dedicated app or a terminal application (ThinQ App) for managing / operating the dishwasher (10) (S101).

[0400] This course information may include the washing and drying stages and noise levels of the course, along with information on the estimated energy consumption (estimated power consumption) and estimated time required for the corresponding course.

[0401] The terminal device (20) can apply the set course information to the dishwasher (10). To do this, the terminal device (20) can download the corresponding course information to the dishwasher (10) by user input (S102).

[0402] Accordingly, the terminal device (20) can transmit the set course information to the dishwasher (10) in order to download the course information set to the dishwasher (10) (S103).

[0403] The dishwasher (10) downloads and applies course information transmitted from the terminal device (20) (S104), and can operate according to the received course during subsequent operation (S105).

[0404] Afterward, when the dishwasher (10) finishes operating, the end of operation can be notified to the terminal device (20) (S106).

[0405] When the terminal device (20) recognizes the end of the operation of the dishwasher (10) by the notification of the end of the operation, it can display a user interface on the screen that evaluates satisfaction with the course (S107).

[0406] Satisfaction evaluation items may include, for example, items such as washing, drying, and time.

[0407] The satisfaction evaluation can be conducted by the user selecting one of the following for each evaluation item: very dissatisfied, dissatisfied, average, satisfied, or very satisfied.

[0408] The results of the satisfaction evaluation may be reflected in future course changes. In other words, if the satisfaction evaluation is rated as "very dissatisfied" or "dissatisfied," changes to the course may be made.

[0409] This implies that satisfaction with the course is low, so the course is to be modified in a way that can increase satisfaction.

[0410] Accordingly, when a course change is requested based on a satisfaction evaluation (S108), the terminal device (20) changes the currently set first course to a second course reflecting the satisfaction evaluation (S109), and can display the course information before and after the change on one screen simultaneously so that the course information before and after the change can be compared at a glance (S110).

[0411] The fact that a course change is requested in the above S108 step means that at least some of the satisfaction evaluation items are rated as very unsatisfactory or unsatisfactory, and therefore a course change is necessary.

[0412] Accordingly, the terminal control unit (250) can change the course by recognizing that a request for a course change has occurred when the satisfaction evaluation is rated as very dissatisfied or dissatisfied.

[0413] The terminal device (20) can transmit the changed second course to the dishwasher (10) (S111).

[0414] Accordingly, the dishwasher (10) can apply the second course information transmitted from the terminal device (20) by downloading and storing it during the next operation (S112).

[0415] Meanwhile, if there is a satisfaction evaluation in step S108 that does not request a course change, the course change is not made and the course information before the change can be displayed on the screen (S113).

[0416] Here, the existence of satisfaction evaluations that do not request a course change may mean that no satisfaction evaluation was conducted, or that even if an evaluation was conducted, it was rated as average, satisfied, or very satisfied.

[0417] In this way, the present invention allows the terminal device (20) to perform a user satisfaction evaluation for the current first course when the end of operation of the dishwasher (10) is notified, and if the current first course is evaluated as very unsatisfactory or unsatisfactory by the user in the satisfaction evaluation, the evaluation result is reflected and the course is changed to the second course and reflected in the dishwasher (10).

[0418] At this time, one of the important features is that the details of the first course before the change and the second course after the change are displayed together on one screen, allowing the user to quickly check the before and after of the change (see Fig. 15).

[0419] If the satisfaction evaluation for the current first course is not conducted, or if the first course is evaluated as average, satisfactory, or very satisfactory in the satisfaction evaluation, the course change is not conducted and the current first course is maintained in the dishwasher (10).

[0420] As described above, in one embodiment, the course change from the first course to the second course is automatically performed after the satisfaction evaluation and reflects the satisfaction evaluation, but in another embodiment, the user may change the course directly.

[0421] Direct course changes by the user are possible even after a satisfaction evaluation, or even after a satisfaction evaluation has not been conducted.

[0422] FIG. 32 is a flowchart showing the process of a user directly setting course information in a terminal device according to another embodiment of the present invention.

[0423] The drawing explains direct changes to the course after a satisfaction evaluation by the user or after no satisfaction evaluation.

[0424] When the satisfaction evaluation is completed by the user, the user-customized course information that has been changed to reflect the satisfaction evaluation can be displayed on the screen of the terminal device (20) (see FIG. 24).

[0425] Alternatively, if there is no satisfaction evaluation by the user, the information of the current course may be displayed on the screen of the terminal device (20) without changing the course (see FIG. 30).

[0426] On each screen, a menu may be displayed for performing direct course setting by user touch.

[0427] When the direct setting menu is touched (S201), the terminal device (20) may display a user interface on the screen that allows the user to directly set / change the driving conditions for each administration of the current first course by touch or selection as shown in FIG. 25 (S202).

[0428] FIG. 25 illustrates an example of a user interface in the form of a slide bar that allows a terminal device (20) to change the driving conditions of each stroke for course change.

[0429] The user can change the driving conditions of the washing and drying cycles by adjusting the position of the control point of each slide bar.

[0430] Additionally, the user interface may provide buttons for selecting noise levels. The buttons may be displayed as numerical values ​​representing noise levels. In the numerical values ​​of the buttons, Level 1 may mean low noise of relatively low decibels, and Level 2 may mean high noise of relatively high decibels.

[0431] When a course change is requested by the user based on a course change direct by the user (S203), the terminal device (20) changes the current first course to the second course by reflecting the course change direct by the user (S204), and can display the course information before and after the change simultaneously on one screen so that the course information before and after the change can be compared at a glance (S205).

[0432] The terminal device (20) can transmit the changed second course to the dishwasher (10) (S206).

[0433] Accordingly, the dishwasher (10) can apply the second course information transmitted from the terminal device (20) by downloading and storing it during the next operation (S207).

[0434] Meanwhile, in step S203, if the course change is not performed or if the course is changed to the same course as the first course even if the course change is performed, it is determined that no course change is requested and therefore the course change is not performed, so the information of the first course before the change can be displayed on the screen (S208).

[0435] In this way, the present invention allows the terminal device (20) to perform a user satisfaction evaluation for the current first course when the end of operation of the dishwasher (10) is notified, and if the current first course is evaluated as very unsatisfactory or unsatisfactory by the user in the satisfaction evaluation, the evaluation result is reflected and the course is changed to the second course and reflected in the dishwasher (10).

[0436] At this time, one of the important features is that the details of the first course before the change and the second course after the change are displayed together on one screen, allowing the user to quickly check the before and after of the change (see Fig. 15).

[0437] If the satisfaction evaluation for the current first course is not conducted, or if the first course is evaluated as average, satisfactory, or very satisfactory in the satisfaction evaluation, the course change is not conducted and the dishwasher (10) maintains the current first course.

[0438] In this way, the present invention allows the current first course to be changed to the second course by the user directly changing the course at the terminal device (20), so that this is reflected in the dishwasher (10).

[0439] In this case as well, the details of the first course before the change and the second course after the change are displayed together on one screen, allowing the user to quickly check the before and after of the change (see Fig. 28).

[0440] If the user does not directly change the course for the current first course, or if there is no actual change to the course even if the course is directly changed, the current first course is maintained in the dishwasher (10).

[0441] FIG. 33 is a flowchart showing a method for changing the driving conditions of each stroke of a course by reflecting a satisfaction evaluation in a terminal device according to an embodiment of the present invention, and FIG. 34 is a diagram summarizing the change in driving conditions of each stroke of FIG. 33.

[0442] Referring to FIG. 33, when the terminal device (20) receives a notification of the end of operation of the dishwasher (10) (S301), it performs a user satisfaction evaluation for the current course (first course) of the dishwasher (10) (S302).

[0443] When the dishwasher (10) is finished after operating at least once, it can send a notification of the end of operation of the dishwasher (10) to the terminal device (20).

[0444] The end of such washing operation may be transmitted directly by the dishwasher (10) to the terminal device (20), or the server (30) may receive it from the dishwasher (10) and transmit it to the terminal device (20).

[0445] Satisfaction evaluation items may include, for example, items such as washing, drying, and time.

[0446] The satisfaction evaluation can be conducted by the user selecting one of Very Dissatisfied, Dissatisfied, Neutral, Satisfied, and Very Satisfied for each of the above evaluation items.

[0447] The results of the satisfaction evaluation may be reflected in future course changes. In other words, if the satisfaction evaluation is rated as "very dissatisfied" or "dissatisfied," changes to the course may be made.

[0448] This implies that satisfaction with the course is low, so the course is to be modified in a way that can increase satisfaction.

[0449] Satisfaction evaluation can be performed for each item. In this embodiment, for example, each item of washing, drying, and time is set to be evaluated with 1 to 5 stars (see FIG. 13).

[0450] For example, it is set so that 1 star is rated as very dissatisfied, 2 stars as dissatisfied, 3 stars as average, 4 stars as satisfied, and 5 stars as very dissatisfied. Of course, this evaluation method is merely an example, and satisfaction evaluations can be conducted in various ways.

[0451] In the case of changing the course based on the satisfaction evaluation, this embodiment changes the driving conditions of the washing and drying cycles according to the evaluation of the washing and drying cycles based on the evaluation of the time cycle.

[0452] In this embodiment, the change in the steps of the washing and drying process is explained by conducting a satisfaction evaluation with 5 stars as in the example above.

[0453] First, check the star rating for the time item in the satisfaction evaluation. If the star rating for the time item is 2 points or less (S303), check if the star rating for the cleaning item is 2 points or less.

[0454] If the star rating of the washing item is 2 points or less (S304), the star rating of the drying item is checked, and if the star rating of the drying item is 2 points or less (S305), the washing and drying steps are each increased by 1 step (S306).

[0455] If the star rating of the drying item in step S305 is not 2 points or less, this means that the star rating of the drying item is 3 points or more, in this case, the washing process is increased by 1 step and the drying process is maintained at the current step (S307).

[0456] If the star rating of the washing item in step S304 is not 2 points or less, this means that the star rating of the washing item is 3 points or more, and in this case, the star rating of the drying item is checked again. If the star rating of the drying item is 2 points or less (S308), the washing process maintains the current stage and the drying process is increased by 1 stage (S309).

[0457] If the star rating of the drying item in step S308 is not 2 points or less, this means that the star rating of the drying item is 3 points or more, and in this case, the washing and drying steps are each reduced by 1 step (S310).

[0458] If the star rating of the time item in step S303 is not 2 points or less, this means that the star rating of the time item is 3 points or more, in this case, the star rating of the washing item is checked again. If the star rating of the washing item is 2 points or less (S311), the star rating of the drying item is checked, and if the star rating of the drying item is 2 points or less (S312), the washing and drying steps are each increased by 1 step (S313).

[0459] If the star rating of the drying item in step S312 is not 2 points or less, it means that the star rating of the drying item is 3 points or more, in which case the washing process is increased by 1 step and the drying process is maintained at the current step (S314).

[0460] If the star rating of the washing item in step S311 is not 2 points or less, this means that the star rating of the washing item is 3 points or more, and in this case, if the star rating of the drying item is 2 points or less (S315), the washing process maintains the current stage and the drying process is increased by 1 stage (S316).

[0461] If the star rating of the preparatory item in step S315 is not 2 points or less, this means that the star rating of the drying item is 3 points or more, and in this case, the washing and drying processes each maintain their current stages (S317).

[0462] Changes in driving conditions of the washing and drying cycles according to the star rating of the evaluation items shown in Fig. 33, that is, changes in the steps of the washing and drying cycles, can be summarized as shown in the table in Fig. 34.

[0463] In this way, when the operating conditions of the washing and drying process are changed in accordance with the satisfaction evaluation, the steps of the washing and drying process are increased or decreased by only one step. This prevents abrupt changes in energy consumption and time required caused by rapidly changing the washing and drying process by two or more steps, even if the satisfaction evaluation item is rated as very unsatisfactory.

[0464] As described above, the present invention allows a user to set and change the course of a home appliance using a terminal device. At this time, the user interface displayed on the terminal device may be displayed on the home appliance in the same or similar manner.

[0465] Accordingly, the user may check and change the course using the user interface displayed on the terminal device, or may check and change the course using the user interface displayed on the home appliance.

[0466] In addition, the terminal device of the present invention can conduct a user satisfaction evaluation of the course upon notification of the end of operation of the home appliance and control the automatic change of the course by reflecting the satisfaction evaluation. When the course is changed, the course information before and after the change is displayed simultaneously on a single screen on the terminal device, thereby enabling the user to quickly check and understand the effects of the course change on the terminal device.

[0467] Meanwhile, course information before and after the course change can be simultaneously displayed on a single screen of the home appliance, allowing the user to quickly check and understand the effects of the course change on the appliance.

[0468] Although the home appliances described in the above embodiments are specifically limited to dishwashers as an example, this is for the convenience of explanation, and it is obvious that the present invention can be applied to other home appliances capable of performing multiple operations according to a course and setting and changing the course, in addition to dishwashers.

[0469] As described above, even though all components constituting an embodiment according to the present invention have been described as being combined or operating in combination, the present invention is not necessarily limited to such an embodiment. That is, within the scope of the purpose of the present invention, all components may be selectively combined in one or more ways to operate. Furthermore, terms such as "include," "constitute," or "have" as described above, unless specifically stated otherwise, mean that the relevant component may be inherent; therefore, they should be interpreted as allowing for the inclusion of additional components rather than excluding other components.
