[0010] (Findings that formed the basis of this disclosure) At the time when the inventors came up with the idea of ​​the present disclosure, a technology for changing the control value of a washing machine based on the results of a survey, such as the washing machine management system disclosed in Patent Document 1, was known. However, even if a user of a home appliance is dissatisfied with the results obtained by operating the appliance, they may not be able to know how to set the appliance to resolve the dissatisfaction. For example, if the appliance is a washing machine, simply changing the operating parameters that control the washing machine, such as the amount of detergent or the wash time, may not be enough to resolve the dissatisfaction.

[0011] In addition, home appliance developers design operating programs that combine a large number of operating parameters to control the appliance so as to obtain effects suited to the purpose and object, and install these operating programs in the appliances. Home appliances are equipped with many operating programs for different purposes. The inventors of the present invention have discovered that home appliance users are not able to master many of the operating programs, and furthermore, even if an operating program that is likely to resolve their dissatisfaction is installed in the appliance, they may not be able to use the operating program. Therefore, the present disclosure provides a home appliance system, a program, and a satisfaction improvement method that increase the satisfaction of users of home appliances.

[0012] Hereinafter, embodiments will be described in detail with reference to the drawings. However, in some cases, more detailed explanation than necessary may be omitted.

[0040] The display control unit 253 causes the terminal processor 270 to execute the APP 263, thereby causing the APP screen 240 to be displayed on the touch panel 230. The APP screen 240 includes, for example, an initial setting screen (not shown). The initial setting screen is a screen that accepts input of initial settings such as the user's name, password, address, user ID, email address, washing machine ID, type of laundry detergent being used, and remaining amount of laundry detergent. Furthermore, the APP screen 240 displays questionnaire screens including a first questionnaire screen 500, a second questionnaire screen 600, and a third questionnaire screen 700. The display control unit 253 causes the touch panel 230 to display the questionnaire screens based on the questionnaire data received from the management server 300.

[0041] [4. Management Server Configuration] 4 is a diagram showing the configuration of the management server 300. The management server 300 corresponds to an example of an information processing device. The management server 300 is a computer device including a server communication I / F 310 and a server control unit 330.

[0042] Server communication I / F 310 includes a network adapter such as a network interface card (NIC), and performs data communication with washing machine 100 and terminal device 200 via communication network 5.

[0043] The server control unit 330 is a computer device that includes a server storage unit 340 and a server processor 350.

[0044] The server storage unit 340 includes a non-volatile semiconductor memory or a combination of volatile and non-volatile semiconductor memories, and also includes an auxiliary storage device such as an SSD (Solid State Drive) or an HDD (Hard Disk Drive).

[0045] The server storage unit 340 stores a control program 341, a user database 343, and a usage status management database 345. Hereinafter, the database will be abbreviated as DB.

[0046] FIG. 5 is a diagram showing an example of the configuration of the user DB 343. As shown in FIG. One record of the user DB 343 includes a user ID, name, password, address, email address, washing machine ID, etc. This information is information about the initial settings received by the terminal device 200 on the initial setting screen displayed as the APP screen 240. The terminal device 200 transmits the information about the initial setting received on the initial setting screen to the management server 300.

[0047] FIG. 6 is a diagram showing an example of the configuration of the usage status management DB 345. As shown in FIG. Each record in the usage status management DB 345 includes a user ID, a washing machine ID, the detergent used, the operation date and time, the operation course, and the amount of detergent used. This information is registered in the usage status management DB 345 based on the operation data received from the terminal device 200.

[0048] The server processor 350 is an arithmetic processing unit configured with a CPU or an MPU. The server processor 350 may be configured with a single processor, or may be configured with multiple processors.

[0049] The server control unit 330 includes, as functional components, a server communication control unit 351, a questionnaire management unit 353, and a determination unit 355. These functional components are realized by the server processor 350 executing the control program 341.

[0050] Server communication control unit 351 performs data communication with terminal device 200 and washing machine 100 possessed by the user via server communication I / F 310.

[0051] The questionnaire management unit 353 acquires questionnaire data by generating questionnaire data or reading out previously generated questionnaire data from the server storage unit 340, and outputs the acquired questionnaire data to the server communication control unit 351. The questionnaire data is transmitted to the terminal device 200 under the control of the server communication control unit 351.

[0052] Determination unit 355 determines whether the user is satisfied with the laundry, which is the result of washing machine 100 executing an operating program. For example, determination unit 355 determines whether the user's satisfaction with laundry is low based on a comparison between an input regarding satisfaction with the operating program executed before the operating parameters are changed and an input regarding satisfaction with the operating program after the operating parameters are changed. In other words, determination unit 355 determines whether to output an output to improve the user's satisfaction, such as a suggestion display encouraging a change to the second operating program or a third questionnaire for identifying items with low satisfaction in more detail. Note that determination unit 355 may determine the user's satisfaction based on the input regarding satisfaction, or may directly determine whether or not to output an output from the input value regarding satisfaction.

[0053] [5. Management Server Operation] 7 to 9 are flowcharts showing the operation of the management server 300. The operation of the management server 300 will be described with reference to the flowcharts shown in FIGS. First, the server control unit 330 selects a user ID to be processed. The server control unit 330 determines whether a predetermined period has elapsed since the first questionnaire was sent to the email address associated with the selected user ID (step S1). If the predetermined period has not elapsed (step S1 / NO), the server control unit 330 waits until the predetermined period has elapsed before sending the first questionnaire to the email address associated with the selected user ID. The server control unit 330 then selects the next user ID to be processed. Note that in this embodiment, a case will be described in which the first questionnaire is sent to the email address associated with the user ID. However, the questionnaire may be sent by a push server provided separately from the management server 300 to the touch panel 230 of the terminal device 200 via push notification. In this case, the terminal device 200 may display the questionnaire as a pop-up even if the APP 263 is not running.

[0054] When a predetermined period of time has passed since the previous transmission of the first questionnaire (step S1 / YES), server control unit 330 acquires the questionnaire data of the first questionnaire from server storage unit 340 (step S2). Server control unit 330 transmits the acquired questionnaire data of the first questionnaire to target terminal device 200 (step S3). Washing machine 100 performs a wash operation according to, for example, a predetermined operating course to wash laundry. This predetermined operating course may be selected by the user or may be an operating course set by default in washing machine 100. This predetermined operating course corresponds to the first operating course.

[0055] Here, the first questionnaire will be explained. 10 is a diagram showing an example of a first questionnaire screen 500 displayed on the touch panel 230 of the terminal device 200. The first questionnaire screen 500 is a screen that is displayed when the terminal control unit 250 executing the APP 263 displays on the touch panel 230 an image based on questionnaire data received from the management server 300. When the user inputs information into the first questionnaire screen 500 displayed on the touch panel 230, the terminal device 200 accepts the input regarding the first satisfaction level.

[0056] The first questionnaire displayed on first questionnaire screen 500 is a questionnaire that is sent to terminal device 200 every time a preset period has elapsed, and is a questionnaire that evaluates an operating program that is frequently used by the user. The preset period may be, for example, one month, three months, or six months, but management server 300 may send the first questionnaire to terminal device 200 every time washing machine 100 is used a preset number of times. First questionnaire screen 500 includes operating program name 501 to be evaluated, questionnaire items 503, and satisfaction level input field 505 in which the user inputs the degree of satisfaction.

[0057] The questionnaire items 503 include, for example, items such as stain removal, odor, wrinkles, dryness, etc. These questionnaire items 503 correspond to the first questionnaire items. Five shapes are arranged horizontally in the satisfaction level input field 505. Fig. 10 shows an example in which a star-shaped shape is displayed as the shape, but the shape of the shape may be other than a star, such as a circle, a triangle, or a rectangle. The five shapes are displayed for each of the multiple questionnaire items 503.

[0058] The user evaluates each questionnaire item of dirt removal, odor, wrinkles, and dryness on a five-point scale, and inputs the degree of satisfaction for each questionnaire item 503 by touching the touch panel 230. In the example shown in Fig. 10, the higher the satisfaction level, the more black star shapes there are, and the lower the satisfaction level, the more white star shapes there are.

[0059] The first questionnaire screen 500 also displays a send button 507 and a cancel button 509. The send button 507 is a button for sending the survey results of the first questionnaire to the management server 300. The cancel button 509 is a button for canceling the satisfaction level that has been input in the satisfaction level input field 505.

[0060] Returning to FIG. 7, the operation of the management server 300 will be described. Next, the server control unit 330 determines whether or not the survey result of the first survey has been received from the terminal device 200 (step S4). If the survey result of the first survey has not been received (step S4 / NO), the server control unit 330 waits until the survey result of the first survey is received.

[0061] When the server control unit 330 receives the survey results of the first survey (step S4 / YES), the server control unit 330 stores the received survey results of the first survey in the server storage unit 340 (step S5).

[0062] Next, server control unit 330 acquires the results of the first questionnaire from server storage unit 340 (step S6), and determines, based on the acquired results of the first questionnaire, whether there is any questionnaire item for which the user is dissatisfied with the laundry washed by washing machine 100 (step S7). The operation when the user is not dissatisfied with the laundry washed by washing machine 100 will be described with reference to the flowchart shown in FIG.

[0063] The server control unit 330 may determine whether the user is satisfied with the laundry each time the survey results of the first survey are stored in the server memory unit 340, or may determine whether the user is satisfied with the laundry after a predetermined number of survey results for the same user ID have been stored in the server memory unit 340.

[0064] For example, the server control unit 330 determines that a questionnaire item with three or more black star symbols is an item with which the user is satisfied. The server control unit 330 also determines that a questionnaire item with two or less black star symbols is an item with which the user is not very satisfied. When making a determination based on the survey results of a plurality of first surveys, the server control unit 330 may calculate an average value for each of the plurality of survey items and determine whether or not the user is satisfied based on the calculated average value.

[0065] If there is any survey item for which the user is dissatisfied with the laundry (step S7 / YES), the server control unit 330 determines the operating parameters to be changed and the set values ​​of the operating parameters based on the survey items of the first survey and the satisfaction level for each survey item (step S8). For example, if the survey item for which the user is least satisfied is "stain removal," the server control unit 330 determines parameters to change at least one of the washing time and the amount of detergent used by the washing machine 100. The washing time and the amount of detergent to be changed may also be set according to the level of dissatisfaction of the user.

[0066] Next, server control unit 330 transmits a change request including the determined operating parameters and the values ​​of these operating parameters to washing machine 100 (step S9). Note that the change request including the operating parameters and the values ​​of these operating parameters may be transmitted to terminal device 200. In this case, when using washing machine 100, the user sets washing machine 100 according to the operating parameters and the values ​​of the operating parameters displayed on terminal device 200. For example, the user changes at least one of the washing time and the amount of detergent according to the operating parameters and the values ​​of the operating parameters.

[0067] Next, server control unit 330 determines whether or not operation data has been received from washing machine 100 (step S10). That is, server control unit 330 determines whether or not washing machine 100 has operated after the change in operation parameters based on whether or not operation data has been received from washing machine 100. The operation course of washing machine 100 after the change in operation parameters is referred to as a post-change first operation course.

[0068] If the server control unit 330 has not received operation data from the washing machine 100 (step S10 / NO), the server control unit 330 waits until the operation data is received. If the server control unit 330 receives operation data from the washing machine 100 (step S10 / YES), the server control unit 330 proceeds to the process of step S11. The determination in step S10 may be set to be positive not only when the operation data is received from the washing machine 100 once, but also when the operation data is received multiple times. This is because a user's impressions of the laundry may not be consolidated in a single wash by the washing machine 100.

[0069] When server control unit 330 receives the operation data from washing machine 100 (step S10 / YES), it acquires the first questionnaire from server storage unit 340 (step S11) and resends the first questionnaire (step S12). Server control unit 330 resends the first questionnaire to terminal device 200 to which it was sent in step S3.

[0070] Next, the server control unit 330 determines whether or not the survey result of the first survey has been received from the terminal device 200 (step S13). If the survey result of the first survey has not been received (step S13 / NO), the server control unit 330 waits until the survey result is received.

[0071] When the server control unit 330 receives the survey result of the first survey (step S13 / YES), the server control unit 330 stores the received survey result of the first survey in the server storage unit 340 (step S14).

[0072] Next, the server control unit 330 acquires the survey results of the first survey from the server storage unit 340 (step S15). Based on the acquired survey results, the server control unit 330 determines whether there is any survey item for which the user is dissatisfied with the laundry (step S16). The operation when there is no survey item for which the user is dissatisfied with the laundry in step S7 or step S16 will be described with reference to the flowchart shown in FIG.

[0073] The server control unit 330 determines whether the user is satisfied based on a comparison between the input results of the first questionnaire for the operating course executed before the operating parameters were changed and the input results of the first questionnaire for the operating course after the operating parameters were changed. For example, the server control unit 330 compares the survey results of the first questionnaire executed before the operating parameters were changed, for which the user was dissatisfied, with the survey results of the first questionnaire executed before the operating parameters were changed, for which the user was dissatisfied. If the survey results of the survey items for which the user was dissatisfied are the same or the evaluation has decreased, the server control unit 330 determines that the user is not satisfied.

[0074] Next, the operation when the user is dissatisfied with any questionnaire item in the laundry will be described with reference to the flowchart shown in FIG. If the server control unit 330 determines based on the results of the first questionnaire that there is an item about which the user is dissatisfied with the laundry (step S16 / YES), it acquires the questionnaire data of the third questionnaire from the server storage unit 340 (step S17).

[0075] Here, the third questionnaire will be described with reference to FIG. FIG. 11 is a diagram showing the third questionnaire screen 600. The third questionnaire screen 600 is an additional questionnaire for the questionnaire items for which satisfaction was low in the first questionnaire. In other words, the third questionnaire is a questionnaire for further identifying the reasons for the low satisfaction for the questionnaire items for which satisfaction was low. When the user inputs information into the third questionnaire screen 600 displayed on the touch panel 230, the terminal device 200 accepts input regarding the second satisfaction level.

[0076] The third questionnaire screen 600 displays, for example, a plurality of radio buttons 601, text 603 displayed in association with each of the plurality of radio buttons 601, a send button 605, and a cancel button 607. For example, if the questionnaire item with low satisfaction in the first questionnaire was stain removal, text 603 specifying the type of stain, such as mud stains, yellowing and sebum stains, oil stains, food spills, blackening, etc. The user selects the type of stain that is causing the questionnaire item with low satisfaction by touch operation and presses the send button 605.

[0077] The server control unit 330 transmits the acquired third questionnaire to the terminal device 200 used by the target user (step S18). Next, the server control unit 330 determines whether or not the questionnaire result of the third questionnaire has been received from the terminal device 200 (step S19).

[0078] If the server control unit 330 has not received the survey results for the third survey from the terminal device 200 (step S19 / NO), it waits until it receives the survey results from the terminal device 200. Furthermore, if the server control unit 330 receives the survey results for the third survey from the terminal device 200 (step S19 / YES), it stores the received survey results for the third survey in the server storage unit 340 (step S20).

[0079] Next, server control unit 330 acquires the results of the third questionnaire from server storage unit 340 (step S21) and determines an operating course based on the acquired results of the third questionnaire (step S22). The determined operating course is hereinafter referred to as the second operating course. When changing the parameters, the amount of detergent added and the washing time can be changed, but the number of operation steps performed in the washing operation cannot be increased or the order of the operation steps cannot be changed. If server control unit 330 determines that changing the parameters will not result in a low level of user satisfaction, it determines an operating course to be executed by washing machine 100. Server control unit 330 transmits information about the determined second operating course to terminal device 200 (step S23) and displays a proposal for the second operating course on touch panel 230 of terminal device 200.

[0080] Next, the operation when there is no questionnaire item for which the user is dissatisfied with the laundry in step S7 or step S16 will be described with reference to the flowchart shown in FIG. If the server control unit 330 determines based on the acquired survey results that there are no survey items that the user is dissatisfied with (step S7 / NO or step S16 / NO), it acquires survey data for the second survey from the server storage unit 340 (step S24).The server control unit 330 transmits the acquired survey data for the second survey to the terminal device 200 used by the target user (step S25).

[0081] Here, the second questionnaire will be described with reference to FIG. FIG. 12 is a diagram showing a second questionnaire screen 700. The second questionnaire screen 700 is an additional questionnaire to be conducted when there is no questionnaire item with low satisfaction in the first questionnaire. The second questionnaire includes second questionnaire items, which are questionnaire items other than the first questionnaire items included in the first questionnaire. In other words, the second questionnaire is a questionnaire to identify additional factors, such as concerns about pollen on clothes or viruses on clothes, rather than factors that occur in laundry due to the performance of the washing machine 100, such as dirt removal, odor, or wrinkles. When the user inputs information into the second questionnaire screen 700 displayed on the touch panel 230, the terminal device 200 accepts input regarding the third satisfaction level.

[0082] The second questionnaire screen 700 displays a plurality of radio buttons 701 and text 703 indicating the questionnaire item displayed in association with each of the plurality of radio buttons 701. The third questionnaire screen 700 also displays a send button 705 and a cancel button 707.

[0083] 12, the example of the second questionnaire screen 700 displays questionnaire items such as towels are stiff, I'm concerned about pollen on my clothes, I'm concerned about viruses on my clothes, I want to prevent mold in the tub, nothing in particular, etc. If the user is concerned about any of the questionnaire items, they can select the corresponding item and press the send button 705.

[0084] The operation of the server control unit 330 will now be described. Next, the server control unit 330 determines whether or not the survey result of the second survey has been received from the terminal device 200 (step S26). If the survey result of the second survey has not been received from the terminal device 200 (step S26 / NO), the server control unit 330 waits until the survey result is received.

[0085] When the server control unit 330 receives the survey results of the second survey from the terminal device 200 (step S26 / YES), the server control unit 330 stores the received survey results of the second survey in the server storage unit 340 (step S27).

[0086] Next, the server control unit 330 acquires the results of the second questionnaire from the server storage unit 340 (step S28) and selects a recommended operating program based on the acquired results of the second questionnaire (step S29). The operating program selected here is referred to as the third operating program. The server control unit 330 transmits the acquired information about the third operating program to the terminal device 200 (step S30). FIG. 13 shows an example of a screen displayed on the touch panel 230 of the terminal device 200 that has received the third operating program information. The APP screen 240 shown in FIG. 13 displays a program description 241 for the 40°C soaking program selected as the third operating program, a TRY button 242, and a CLOSE button 243. When the TRY button 242 is pressed, the terminal control unit 250 transmits a change instruction to the washing machine 100 to change the operating program to the 40°C soaking program. When the CLOSE button 243 is pressed, the terminal control unit 250 closes the display of the APP screen 240.

[0087] 6. Effect of the embodiment The home appliance system 1 according to the embodiment is a system including a washing machine 100, a terminal device 200, and a management server 300. The washing machine 100 includes an operation control unit 171 that causes the home appliance to execute a first operation program including predetermined operation parameters. The terminal device 200 includes a touch panel 230 that functions as an input unit and an output unit. Touch panel 230 receives an input regarding a first degree of satisfaction of the user with respect to a result obtained by executing the first operation program by washing machine 100. In addition, touch panel 230 outputs a suggestion regarding an operation program to be executed by washing machine 100. The management server 300 includes a determination unit 355 that determines whether or not to cause the terminal device 200 to output a suggestion regarding driving, based on the first questionnaire received by the terminal device 200.

[0088] When operation control unit 171 of washing machine 100 executes a first operating course after modification, which is a first operating course in which the operating parameters have been modified, touch panel 230 accepts a first questionnaire regarding the results obtained by operating the first operating course after modification. Furthermore, when the management server 300 determines that the user's satisfaction level is low, the touch panel 230 outputs a proposal for a second operating program that is different from the first operating program, based on the input of the first questionnaire.

[0089] According to this configuration, when the home appliance executes an altered first operating program in which the operating parameters of the first operating program have been changed, it accepts input of a first questionnaire regarding the result obtained by operating the altered first operating program. If it is determined that the user's satisfaction with the result is low, a proposal regarding a second operating program that is different from the first operating program and that is selected based on the input of the first questionnaire is output. Therefore, if the user is not satisfied with the result simply by changing the operating parameters, the second operating program selected based on the input of the first questionnaire is proposed to the user. This makes it possible to increase user satisfaction.

[0090] The input of the first questionnaire includes a plurality of items for evaluating the first operating program. A suggestion for the second operating program is output to the touch panel 230 based on the items for which the user is least satisfied.

[0091] According to this configuration, a proposal for a second operating program is output based on the items determined to have low user satisfaction. This makes it possible to propose a second operating program that can improve the items for which the user has low satisfaction. This makes it possible to increase user satisfaction.

[0092] The touch panel 230 accepts a third questionnaire having additional items that further specify items determined to have low user satisfaction. The touch panel 230 also outputs a proposal for a second operating program based on the input of the third questionnaire.

[0093] According to this configuration, an input regarding a second satisfaction level that further specifies the items determined to have low user satisfaction is accepted, and a proposal regarding a second operating program is output based on the input regarding the second satisfaction level. This makes it possible to specify in more detail the items determined to have low user satisfaction, and to propose a second operating program that can improve the more specifically specified items with low satisfaction. This makes it possible to increase user satisfaction.

[0094] The determination unit 355 determines whether to output a proposal for a second operating course different from the first operating course based on a comparison between the input of the first questionnaire for the first operating course executed before the operating parameters were changed and the input of the first questionnaire for the changed first operating course.

[0095] According to this configuration, whether to output a proposal for a second operating program different from the first operating program is determined based on a comparison between an input related to the first satisfaction level for the first operating program and an input related to the first satisfaction level for the changed first operating program. This makes it possible to accurately determine whether to output a proposal for the second operating program.

[0096] When the determination unit 355 determines that the user is satisfied with the laundry based on the input in the first questionnaire, the touch panel 230 accepts input in response to a second questionnaire that includes questionnaire items other than those included in the first questionnaire.

[0097] Therefore, even if the user is satisfied with the result, the user's satisfaction can be further increased.

[0098] The touch panel 230 outputs a proposal regarding a third operating program that is different from the first operating program and the second operating program, based on the user's input to the second questionnaire.

[0099] With this configuration, a proposal for the third operating program is output based on the user's input to the second questionnaire. Therefore, even if the user is satisfied with the result, it is possible to propose an operating program that will further increase the user's satisfaction.

[0100] [7. Other Configurations] The above-described embodiments are intended to illustrate the technology of the present disclosure, and various modifications, substitutions, additions, omissions, etc. may be made within the scope of the claims or their equivalents.

[0101] For example, in the above-described embodiment, the home appliance is the washing machine 100, but the home appliance is not limited to the washing machine 100 and may be, for example, a rice cooker, a dishwasher, or a cooking appliance.

[0102] When the home appliance is a cooker, parameters for changing the degree of heating or stirring correspond to the operation parameters, and when the home appliance is a cooker, a cooking sequence corresponds to the operation course.

[0103] Furthermore, the operation parameters may be changed manually by the user operating the washing machine 100 or the terminal device 200. For example, in the first embodiment, as shown in steps S1 to S3 of the flowchart in FIG. 7, a configuration has been described in which a first questionnaire is acquired and transmitted after a predetermined period of time has elapsed. When the changed first operating course is executed, an input regarding the first satisfaction level with respect to the result obtained by running the changed first operating course is accepted. Therefore, the timing of the input regarding the first satisfaction level is not limited to when a predetermined period of time has elapsed. For example, the input regarding the satisfaction level may be accepted each time the first operating course is completed, or once every multiple operations. Alternatively, the input regarding the satisfaction level may be accepted only after running the changed first operating course, triggered by the operation of the changed first operating course. Alternatively, the input regarding the satisfaction level may be accepted each time the first operating course is completed, but a suggestion regarding a second operating course may be output only when the changed first operating course is executed and the user's satisfaction level is low.

[0104] In the above-described embodiment, a questionnaire has been described as an example of a method for accepting input regarding satisfaction with the laundry, which is the result. The method for accepting input regarding satisfaction with the result or proposing an operation program for washing machine 100 is not limited to a questionnaire, and an interactive input system such as a chatbot may be used. A chatbot is a type of bot or robot that chats with a user (dialogue based on text data).

[0105] 14 to 17 are diagrams showing examples of a chatbot screen 280 that the management server 300 causes to be displayed on the touch panel 230 of the terminal device 200. FIG. Chatbot screen 280 shown in FIG. 14 is a screen corresponding to the first questionnaire shown in FIG. 10 and the third questionnaire shown in FIG. 11. When washing machine 100 finishes washing, management server 300 displays message 281 inquiring about the satisfaction level of the laundry on touch panel 230 of terminal device 200. If the user is not satisfied with the laundry, the user inputs message 282 indicating the dissatisfaction. For example, as shown in FIG. 14, message 282 such as "the stains were not removed" is input. Management server 300 determines that negative message 282 such as "the stains were not removed" is an input related to satisfaction level and indicates low satisfaction level.

[0106] If the user is satisfied with the laundry, they may input words of gratitude such as "thank you." The management server 300 may determine that input of positive expressions, such as words of gratitude, is an input with a high level of satisfaction. On the other hand, the management server 300 may determine that input of negative expressions is an input with a low level of satisfaction. If the management server 300 is unable to determine whether the user's input is an input related to satisfaction, or if it is unable to determine the level of satisfaction, it may display an additional message and extract input related to satisfaction from multiple exchanges.

[0107] When message 282 indicating low satisfaction is input, management server 300 displays message 283 asking the user about the reason for the low satisfaction, i.e., the type of dirt. In the example shown in FIG. 14, message 283 asking what kind of "dirt" is displayed. This message 283 corresponds to the third questionnaire. In response to message 283, the user inputs message 284 indicating the reason for dissatisfaction. In the example shown in FIG. 14, message 284 such as "It's muddy" is input.

[0108] FIG. 15 shows an example of a message that the management server 300 displays when a user inputs a message indicating dissatisfaction with the muddy stains. In response to a message 284 indicating that the cause of low satisfaction is muddy stains, the management server 300 displays a message 285 suggesting an operating course and an explanation 286 of the proposed operating course. FIG. 15 shows an example in which a 40°C soaking course is proposed as the proposed operating course. The proposed operating course corresponds to the course identified in the third questionnaire. A Try button 287 and a Close button 288 are displayed in the explanation of the operating course. The operating course suggested in the explanation 286 of the operating course corresponds to the second operating course.

[0109] The chatbot screen 280 shown in FIG. 16 is a screen corresponding to the second questionnaire shown in FIG. The management server 300 displays a message 291 asking about the user's satisfaction with the finished laundry. When the user inputs a message 292 indicating that they are satisfied with the laundry, the management server 300 displays a message 293, similar to the second questionnaire, asking about additional factors such as whether they are concerned about pollen on their clothes or viruses on their clothes. If the user has any concerns about the laundry, they input a message 294. The example shown in FIG. 16 shows a case where the user inputs a message 294 indicating that the towels are stiff.

[0110] FIG. 17 is a screen showing a response to message 294 entered by the user. For example, in the screen shown in FIG. 16, when a message 294 saying "The towel is stiff" is input, the management server 300 displays a message 295 suggesting a driving course that can improve this problem, and an explanation 296 of the suggested driving course, as shown in FIG. 17. 17 shows an example in which a towel-only program is suggested as the operation program. In the explanation 296 of the operation program, a try button 297 and a close button 297 are displayed.

[0111] Furthermore, the method of receiving input regarding satisfaction with the laundry, which is the result, may be voice input.

[0112] In addition, in the above-described embodiment, whether the user is satisfied is determined based on a comparison between the input results of the first questionnaire for the operating course executed before the operating parameters were changed and the input results of the first questionnaire for the operating course executed after the operating parameters were changed. Alternatively, it may be determined whether the user is satisfied with the laundry based on the input result of the first questionnaire only after the parameter change. In other words, the user's satisfaction with the laundry may be determined from the input result of a single questionnaire.

[0113] In the above-described embodiment, the configuration has been described in which management server 300 includes a determination unit and determines whether the user's satisfaction with the laundry is low or not. However, washing machine 100 or terminal device 200 may function as the determination unit. In addition, in the above-described embodiment, the case where touch panel 230 of terminal device 200 functions as an input section and an output section has been described, but touch panel 120 provided in washing machine 100 may also function as an input section and an output section.

[0114] Furthermore, in the above-described embodiment, the output unit displays a suggestion regarding the second operating course on the touch panel 230 of the terminal device 200 as the APP screen 240 or as the chatbot screen 280, but the output unit may also output the suggestion regarding the second operating course by voice.

[0115] Furthermore, the functional units of the management server 300 shown in FIG. 4 represent functional configurations, and the specific implementation form is not particularly limited. In other words, it is not necessary to implement hardware corresponding to each functional unit individually, and it is of course possible to configure the system so that a single processor executes a program to realize the functions of multiple functional units. Furthermore, some of the functions realized by software in the above embodiments may be realized by hardware, and some of the functions realized by hardware may be realized by software. In addition, the specific detailed configurations of other units of the projector may also be changed as desired without departing from the spirit of the present invention. The same applies to the configuration of the washing machine 100 shown in FIG. 2 and the configuration of the terminal device 200 shown in FIG. 3.

[0116] 7 to 9 are divided into processing units according to the main processing content in order to make the processing of the management server 300 easier to understand. The present invention is not limited by the manner in which the processing units are divided or the names of the processing units shown in the flowcharts of FIGS. 7 to 9. Furthermore, the processing of the management server 300 can be divided into more processing units according to the processing content, or one processing unit can be divided so that it includes more processes. Furthermore, the processing order of the above flowcharts is not limited to the example shown in the drawings.

[0117] Furthermore, when the program is implemented using server processor 350 included in management server 300, the program executed by the processor can be configured as a processor-readable, non-transitory recording medium. Alternatively, the program can be configured as a transmission medium for transmitting the program executed by the processor. The recording medium can be a magnetic or optical recording medium or a semiconductor memory device. Specific examples include portable or fixed recording media such as flexible disks, hard disk drives (HDDs), CD-ROMs, digital versatile discs (DVDs), Blu-ray (registered trademark) discs, magneto-optical discs, flash memories, and card-type recording media. Furthermore, the recording medium can be a non-volatile storage device such as RAM, ROM, or HDD, which is an internal storage device included in management server 300 and washing machine 100.

[0118] [8. Notes] The above description of the embodiments discloses the following techniques.

[0119] (Technology 1) A home appliance system comprising: an operation control unit that causes a home appliance to execute a first operating course including predetermined operating parameters; an input unit that accepts input regarding a user's first satisfaction level with respect to an outcome obtained by the operation control unit executing the first operating course; an output unit that outputs a suggestion regarding the operation to be executed by the home appliance; and a judgment unit that judges whether to cause the output unit to output a suggestion based on the input regarding the first satisfaction level accepted by the input unit, wherein when the operation control unit executes a modified first operating course, which is the first operating course in which the operating parameters have been changed, the input unit accepts input regarding the first satisfaction level with respect to an outcome obtained by operating the modified first operating course, and the output unit outputs a suggestion regarding a second operating course different from the first operating course based on the input regarding the first satisfaction level.

[0120] According to this configuration, when the home appliance executes an altered first operating program in which the operating parameters of the first operating program have been changed, the home appliance receives an input regarding a first satisfaction level with respect to an outcome obtained by operating the altered first operating program. The output unit outputs a proposal regarding a second operating program different from the first operating program based on the input regarding the first satisfaction level. Therefore, if the user is not satisfied with the outcome by simply changing the operating parameters, the second operating program selected based on the input regarding the first satisfaction level is proposed to the user. This can increase user satisfaction.

[0121] (Technology 2) The input regarding the first satisfaction level includes a plurality of items for evaluating the first operating course, and the output unit outputs a suggestion regarding the second operating course based on the items determined to have low satisfaction levels.

[0122] According to this configuration, a proposal for a second operating program is output based on the items determined to have low user satisfaction. This makes it possible to propose a second operating program that can improve the items for which the user has low satisfaction. This makes it possible to increase user satisfaction.

[0123] (Technology 3) The input unit receives an input regarding a second satisfaction level having an additional item that further identifies the item with low satisfaction, and the output unit outputs a suggestion regarding the second operating course based on the input regarding the second satisfaction level.

[0124] According to this configuration, an input regarding a second satisfaction level that further identifies items for which the user has low satisfaction is accepted, and a proposal regarding a second operating program is output based on the input regarding the second satisfaction level. This makes it possible to identify in more detail the items for which the user has low satisfaction, and to propose a second operating program that can improve the more specifically identified items for which satisfaction is low. This makes it possible to increase the user's satisfaction.

[0125] (Technology 4) The home appliance system described in Technology 1, wherein the determination unit determines whether to output a suggestion for a second operating program different from the first operating program based on a comparison between an input regarding the first satisfaction level for the first operating program executed before the operating parameters were changed and an input regarding the first satisfaction level for the first operating program after the change.

[0126] According to this configuration, whether to output a proposal for a second operating program different from the first operating program is determined based on a comparison between an input related to the first satisfaction level for the first operating program and an input related to the first satisfaction level for the changed first operating program. This makes it possible to accurately determine whether to output a proposal for the second operating program different from the first operating program.

[0127] (Technology 5) The home appliance system according to technology 1, wherein the input unit receives an input to a first questionnaire that is presented to the user so that the input is available, as an input regarding the first satisfaction level.

[0128] According to this configuration, an input regarding the first satisfaction level can be received by inputting the first questionnaire, and therefore the satisfaction level of the user can be obtained in a simple manner.

[0129] (Technology 6) The home appliance system described in Technology 5, wherein the output unit is presented to the user so that the user can input a second questionnaire that includes second questionnaire items other than the first questionnaire items included in the first questionnaire, when the determination unit determines that the user is satisfied with the result based on the input regarding the first satisfaction level, and accepts input regarding a third satisfaction level.

[0130] According to this configuration, if the user is satisfied with the result, an input to the second questionnaire including second questionnaire items other than the first questionnaire items included in the first questionnaire is accepted as an input regarding the third satisfaction level. Therefore, even if the user is satisfied with the result, the user's satisfaction can be further increased.

[0131] (Technology 7) The home appliance system described in Technology 6, wherein the output unit outputs a proposal regarding a third operating program different from the first operating program and the second operating program based on the user's input for the second questionnaire item of the second questionnaire.

[0132] With this configuration, a proposal for the third operating program is output based on the user's input for the second questionnaire item in the second questionnaire. Therefore, even if the user is satisfied with the result, it is possible to propose an operating program that will further increase the user's satisfaction.

[0133] (Technology 8) A program to be executed by a processor mounted on an information processing device, the program causing the processor to execute the following: a reception process for receiving input regarding a user's first satisfaction level with a result obtained when a home appliance executes a first operating course including predetermined operating parameters; an output process for outputting a suggestion regarding the operation to be executed by the home appliance; and a determination process for determining whether or not to cause the output process to output a suggestion based on the input regarding the first satisfaction level received in the reception process, wherein when the home appliance executes a modified first operating course, which is the first operating course in which the operating parameters have been changed, the reception process receives input regarding the first satisfaction level with a result obtained by operating the modified first operating course, and the output process outputs a suggestion regarding a second operating course different from the first operating course, based on the input regarding the first satisfaction level.

[0134] According to this, when the home appliance executes an altered first operating program in which the operating parameters of the first operating program have been changed, an input regarding a first satisfaction level with respect to an outcome obtained by operating the altered first operating program is received. The output unit outputs a proposal regarding a second operating program different from the first operating program based on the input regarding the first satisfaction level. Therefore, if the user is not satisfied with the outcome by simply changing the operating parameters, the second operating program selected based on the input regarding the first satisfaction level is proposed to the user. This can increase user satisfaction.

[0135] (Technology 9) A satisfaction improvement method comprising: an operating step of causing a home appliance to execute a first operating course including predetermined operating parameters; a reception step of receiving input regarding a user's first satisfaction level with respect to a result obtained by executing the first operating course by the operating step; an output step of outputting a proposal regarding the operating course to be executed by the home appliance; and a determination step of determining whether to cause the output step to output a proposal based on the input regarding the first satisfaction level received in the reception step, wherein when the operating step executes a modified first operating course, which is the first operating course in which the operating parameters have been changed, the reception step receives input regarding the first satisfaction level with respect to a result obtained by operating the modified first operating course, and the output step outputs a proposal regarding a second operating course different from the first operating course, based on the input regarding the first satisfaction level.

[0136] According to this, when the home appliance executes an altered first operating program in which the operating parameters of the first operating program have been changed, an input regarding a first satisfaction level with respect to an outcome obtained by operating the altered first operating program is received. The output unit outputs a proposal regarding a second operating program different from the first operating program based on the input regarding the first satisfaction level. Therefore, if the user is not satisfied with the outcome by simply changing the operating parameters, the second operating program selected based on the input regarding the first satisfaction level is proposed to the user. This can increase user satisfaction. [Industrial Applicability]
