[0028] Hereinafter, an embodiment of one aspect of the present invention will be described with reference to the accompanying drawings. In the following description, the same reference numerals are used to denote the same parts. Their names and functions are also the same. Therefore, detailed descriptions of them will not be repeated.

[0029] <First Implementation>

[0030] <Overall Structure of a Network System>

[0031] First, refer to Figure 1 The overall configuration of the network system 1 in this embodiment will be described. The network system 1 includes, as a main device, a server 100 for providing this service; multiple washing machines 200 configured in each household that exchange data with the server 100 via routers, the Internet, etc.; and communication terminals 300 such as smartphones of users utilizing the washing machines 200.

[0032] <Summary of Network System Operations>

[0033] Next, refer to Figures 1 to 3 The operation overview of the network system 1 in this embodiment will be explained.

[0034] First, the user performs a wash cycle using washing machine 200. When the wash cycle is complete, washing machine 200 sends this information to server 100. At this time, washing machine 200 sends data on various sensor results measured during the wash cycle to server 100. For example, the steps performed, the amount of water used in each step, the time for each step, the amount of laundry, and the degree of soiling are uploaded.

[0035] Server 100 sends a message to the user's communication terminal 300 indicating that the wash cycle has ended and that feedback has been received. Communication terminal 300 receives feedback from the user regarding the current wash cycle and sends it to server 100. Server 100 uses this feedback to adjust various settings in the standard wash program of washing machine 200 and sends this adjusted data back to washing machine 200. Therefore, when executing the next standard wash program, washing machine 200 can perform control that better meets the user's needs.

[0036] In this embodiment, after providing feedback to the server 100, the server 100 sends a report on the sensing results related to the current wash to the communication terminal 300. The communication terminal 300 displays the report related to the sensing results.

[0037] Furthermore, particularly in this embodiment, the server 100 downloads a washing control program, designed to better suit the user's needs, to the washing machine 200 based on feedback from the communication terminal 300 and sensing results from the washing machine 200. For example, when a washing control program is prepared to better suit the user's needs, the server 100 queries the user's communication terminal 300 to request that the control program be downloaded to the washing machine 200. Then, upon receiving an affirmative response from the user, the server 100 downloads the control program to the washing machine 200.

[0038] Thus, the network system 1 of this embodiment is a system that provides the washing machine 200 with a control program for executing a washing process that better meets the user's needs, based on information input by the user to the communication terminal 300 and the washing machine 200, and the sensing results of the washing machine 200. Hereinafter, the configuration of each device used to implement such a function in the network system will be described in detail.

[0039] <Composition of Communication Terminal 300>

[0040] First, one configuration of the communication terminal 300 used by the user of the washing machine 200 will be described. The communication terminal 300 is a device such as a smartphone, wearable device, tablet computer, or personal computer capable of data communication with the server 100. (Refer to...) Figure 4The main components of the communication terminal 300 include a CPU 310, a memory 320, a display 330, an operation unit 340, a communication interface 360, a speaker 370, and a microphone 380.

[0041] CPU 310 controls the various parts of communication terminal 300 by executing programs stored in memory 320 or external storage medium.

[0042] The memory 320 is implemented using various types of RAM (Random Access Memory) and ROM (Read-Only Memory). The memory 320 stores various application programs executed by the CPU 310, data generated by the CPU 310 executing programs, text data, image data, voice data received from the server 100, and data input via the operation unit 340.

[0043] The display 330 outputs characters, images, etc., based on signals from the CPU 310. The operation unit 340 accepts commands from the user and inputs the commands to the CPU 310. The display 330 and the operation unit 340 can also be implemented via a touch panel 350.

[0044] The communication interface 360 ​​is implemented through communication modules such as wireless LAN or wired LAN. The communication interface 360 ​​sends and receives data with other devices such as the server 100 through wired or wireless communication.

[0045] The speaker 370 outputs sound based on the signal from the CPU 310. The microphone 380 generates a sound signal based on external sound and inputs it to the CPU 310.

[0046] In this embodiment, for example, the CPU 310, according to the program in the memory 320 and based on instructions from the server 100, receives washing-related feedback from the user via the operation unit 340, or sends the feedback data to the server 100 via the communication interface 360. Alternatively, the washing machine 200 can also directly receive feedback information via its own user interface.

[0047] Furthermore, in this embodiment, reference is made to Figure 5 The CPU 310, according to the program in the memory 320, receives information from the user regarding the detergent and fabric softener added to the washing machine 200 via the operation unit 340, and sends this information to the server 100 via the communication interface 360. Additionally, as described later, the washing machine 200 can also obtain information regarding the detergent and fabric softener used in the washing machine 200.

[0048] <Composition of Washing Machine 200>

[0049] Next, refer to Figure 6 One configuration of the washing machine 200 constituting the network system 1 will be described. The main components of the washing machine 200 include a CPU 210, a memory 220, a display 230, an operation unit 240, a communication interface 260, a speaker 270, a washing sensor 281, a reading sensor 282, a timer 285, and a device drive unit 290.

[0050] CPU 210 controls various parts of washing machine 200 by executing programs stored in memory 220 or external storage media. For example, CPU 110 controls device drive unit 290 to perform washing operations based on washing control commands, or controls device drive unit 290 to perform drying operations based on drying control commands, or calculates the predetermined end time of washing.

[0051] The memory 220 is implemented using various RAMs, ROMs, etc. The memory 220 stores washing control programs, drying control programs, dialogue programs, or other programs executed by the CPU 210; voice data or other data received from the server 100 or other servers; data input via the operation unit 240; and sensing results measured by various washing sensors 281. Additionally, the memory 120 pre-stores multiple washing control programs, but as described later, new control programs suitable for the washing machine 200 are downloaded and accumulated in the memory 120 based on feedback data and sensing results.

[0052] For example, memory 220 stores Figure 7 The adjustment data shown is used to store, for example, the correspondence between adjustment items, adjustment values, and adjustment contents. More specifically, for each item that is subject to adjustment, such as water volume, washing time, number of spin cycles, and spin time, the correspondence between the adjustment value and the adjustment content from server 100 is stored. For example, regarding water volume, if server 100 provides adjustment value 1, the water volume will be corrected to less than 5 liters compared to the standard; if server 100 provides adjustment value 2, the water volume will be the standard; if server 100 provides adjustment value 3, the water volume will be corrected to more than 5 liters compared to the standard.

[0053] return Figure 6 The display 230 outputs characters, images, etc., based on signals from the CPU 210. The operation unit 240, implemented via buttons, touch panels, etc., accepts various commands from the user and inputs these commands to the CPU 210. Alternatively, the display 230 and the operation unit 240 can also form a touch panel.

[0054] The communication interface 260 is implemented through a communication module such as a wireless LAN or a wired LAN, and exchanges data with other devices such as the server 100 via wired or wireless communication. For example, the CPU 210 sends commands received by the operation unit 240, the scheduled end time of washing, and various sensor data measured during washing to the server 100 via the communication interface 260, or receives adjustment values, control programs, remote control commands, and other data from the server 100 and inputs them into the CPU 210.

[0055] The speaker 270 outputs sound based on signals from the CPU 210. For example, the CPU 210 outputs voice data pre-registered in the memory 220 and voice data received from the server 100 from the speaker 270.

[0056] The washing sensor 281 is a sensor that measures the amount of water used, the weight of the laundry, the opening and closing status of the door, the degree of dirt, etc., and inputs the measurement results to the CPU 210.

[0057] The sensor 282 is a camera, barcode reader, RFID antenna, etc., that reads the QR code (registered trademark) and barcode on the packaging of detergents and fabric softeners, obtains information related to the detergents and fabric softeners, and inputs it into the CPU 210.

[0058] The timer 285 inputs the current time to the CPU 210, or measures the elapsed time from the start of the wash cycle to the end of the wash cycle and inputs it to the CPU 210.

[0059] The device drive unit 290 performs the main functions of the washing machine 200, such as the motor, actuator, and heater. The CPU 210 controls the device drive unit 290 and performs washing based on a pre-prepared control program, or based on feedback data, sensing results, and a new control program downloaded from the server 100.

[0060] <Composition of Server 100>

[0061] Next, the devices constituting network system 1 will be described in detail. First, refer to... Figure 8 The following describes one configuration of the server 100. The server 100 of this embodiment includes a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, and a communication interface 160 as main components.

[0062] CPU 110 controls various parts of server 100 by executing programs stored in memory 120. For example, CPU 110 executes programs stored in memory 120 and performs various processes, described later, by referring to various data.

[0063] The memory 120 is implemented using various RAMs, ROMs, etc. It can be a memory built into the server 100, a memory that can be installed and removed from various interfaces of the server 100, or a storage medium of other devices that can be accessed from the server 100. The memory 120 stores the program executed by the CPU 110, the data generated by the CPU 110 executing the program, user information data 121, washing machine information data 122, program information data 123, feedback corresponding data, adjustment value limit corresponding data, adjustment value fluctuation corresponding data, detergent corresponding data, sensing result corresponding data, and laundry placement corresponding data, etc.

[0064] Reference Figure 9 User information data 121 stores the corresponding relationships of user identification information, username, user communication terminal identification information 300, user address, age, gender and other user attributes for each user registered with this service.

[0065] Reference Figure 10 The washing machine information data 122 stores the corresponding relationships for each washing machine 200 registered with this service, including the identification information of the washing machine 200, the user of the washing machine 200, the information of the detergent, the information of the fabric softener, the actions of the washing machine 200, the various historical records such as sensing results, various adjustment values ​​based on feedback and sensing results, and the information of the control program downloaded to the washing machine 200 based on feedback and sensing results.

[0066] Reference Figure 11 The program information data 123 stores the program identification information, program content, code, and the corresponding relationship of conditions suitable for providing the program to the washing machine 200 for each control program used in the washing machine.

[0067] Reference Figure 12 The feedback data is stored to correspond to the adjustment items and adjustment values ​​corresponding to the feedback from the communication terminal 300.

[0068] Reference Figure 13 The adjustment value limit corresponding data is stored for each adjustment item, and a guidance statement is provided to the communication terminal 300 when the adjustment value reaches the limit. Furthermore, the adjustment value limit corresponding data stores information about the control program preferably downloaded to the washing machine 200, corresponding to the adjustment item and the limit value of the adjustment value. Moreover, if the CPU 110 cannot handle the situation by simply changing the adjustment value of the standard washing program, it provides a new control program to the washing machine 200 via the communication interface 160. For example, a control program that uses more water than the standard washing program, extends the washing time, increases the number of washes, or reduces the spin speed of the washing layer and the amount of detergent compared to the standard washing program can also be prepared.

[0069] Reference Figure 14 The adjustment value fluctuation data is stored in the guidance statement provided to the communication terminal 300 in the case of feedback fluctuation. Furthermore, the control program information preferably downloaded to the washing machine 200 is stored in the corresponding data of adjustment value fluctuation and the repetition of opposite feedback. Moreover, if the CPU 110 cannot cope with the situation by simply changing the adjustment value of the standard washing program, it provides a new control program to the washing machine 200 via the communication interface 160.

[0070] Reference Figure 15 The detergent correspondence data stores the mapping relationship between detergents, fabric softeners, and guiding statements. Furthermore, the detergent correspondence data stores information about the control program preferably downloaded to the washing machine 200, corresponding to the detergent, fabric softener, and combinations thereof. Specifically, the detergent correspondence data is preferably generated by obtaining the preferred mapping relationship between the amount of laundry, the amount of detergent or fabric softener, the washing time, and the amount of water from the detergent or fabric softener manufacturer's server. Then, the CPU 110 generates a preferred control program related to the amount of laundry, the amount of detergent or fabric softener, the washing time, and the amount of water, as well as a control program for levels that cannot be addressed in the feedback, based on the specified detergent and fabric softener information, and provides this to the washing machine 200.

[0071] Reference Figure 16 The sensing result corresponding data stores the correspondence between the sensing results of the washing machine 200 and the guidance statements. Furthermore, the sensing result corresponding data stores information about the control program preferably downloaded to the washing machine 200, corresponding to the sensing results. Specifically, when a large amount of dirt is detected, a control program is created that uses a larger amount of detergent and sets a longer washing time; when detergent foam is detected as difficult to dissipate, a control program is created that sets a larger rinsing time and more rinses; and a control program at a level that cannot be addressed in the feedback is provided to the washing machine 200.

[0072] Reference Figure 17 The system stores adjustment values ​​for laundry placement data, the relationship between placement time from the end of the wash cycle to door opening, and guidance statements. Furthermore, the system stores information from the control program preferably downloaded to the washing machine 200, corresponding to the laundry placement data and notification time. Specifically, it provides the washing machine 200 with control programs that generate more antibacterial detergent when the average placement time is longer, control programs that utilize LED lights, control programs that utilize the airflow function for longer periods, and control programs that cannot handle feedback.

[0073] return Figure 8 The operations unit 140 receives operations from service administrators and others, and inputs various commands to the CPU 110.

[0074] The communication interface 160 transmits various data, such as voice data and control commands, to other devices, such as the washing machine 200 and the communication terminal 300, via the Internet, carrier networks, routers, etc. Conversely, the communication interface 160 receives data from other devices via the Internet, carrier networks, routers, etc., and transmits it to the CPU 110.

[0075] <Functional Composition of Server 100>

[0076] Next, refer to Figure 18 The functions of the server 100 in this embodiment will be described below. In this embodiment, the server 100 mainly implements the functions of the application data receiving unit 111, the washing machine data receiving unit 112, the adjustment value determining unit 113, the guidance statement determining unit 114, the washing machine data sending unit 115, and the application data sending unit 116. Each function will be described in detail below.

[0077] CPU 110 executes the program in memory 120 and, while using communication interface 160, implements application data receiving unit 111. Application data receiving unit 111 receives feedback data from application programs in communication terminal 300, detergent information, fabric softener information, etc.

[0078] The CPU 110 executes the program in the memory 120 and, while using the communication interface 160, implements the washing machine data receiving unit 112. The washing machine data receiving unit 112 receives sensing results, feedback data, detergent information, fabric softener information, etc. from the washing machine.

[0079] CPU 110 executes the program in memory 120 to implement adjustment value determination unit 113. Adjustment value determination unit 113 refers to various data in memory 120 and determines various adjustment values ​​based on feedback data from communication terminal 300 and sensing results from washing machine 200. In addition, adjustment value determination unit 113 determines a control program suitable for washing in washing machine 200 based on feedback data and sensing results.

[0080] The CPU 110 executes the program in the memory 120 to implement the boot statement determination unit 114. The boot statement determination unit 114 refers to various data in the memory 120 and determines various boot statements based on feedback data from the communication terminal 300 and sensing results from the washing machine 200.

[0081] The CPU 110 executes the program in the memory 120 and, while using the communication interface 160, implements the washing machine data transmission unit 115. The washing machine data transmission unit 115 sends adjustment values, guidance statements, control programs, etc., to the washing machine 200.

[0082] The CPU 110 executes the program in the memory 120 and, while using the communication interface 160, implements the application data transmission unit 116. The application data transmission unit 116 sends text data of the guiding statement, voice data, etc., to the application program of the communication terminal 300.

[0083] <Information Processing of Server 100>

[0084] In this embodiment, the CPU 110 of the server 100 executes the following processes according to the program in the memory 120.

[0085] When the washing machine 200 has finished washing, the CPU 110 obtains the sensing results from the washing machine 200 via the communication interface 160 and saves them to the washing machine information data 122 (step S102).

[0086] Next, the CPU110 receives feedback related to the current wash from the user's communication terminal 300 corresponding to the washing machine 200 via the communication interface 160 (step S104).

[0087] CPU110 determines an adjustment value suitable for the feedback and sensing results by referring to various corresponding data (step S106).

[0088] If the setting value can be corrected, that is, if the limit of the setting value has not been reached (if "No" is set in step S108), the CPU110 updates the corresponding setting value of the washing machine 200 and sends an instruction to the washing machine 200 to update the setting value (step S110).

[0089] If the set value cannot be corrected, i.e., the limit of the set value is reached (if "No" is selected in step S110), the CPU 110 refers to the program information data 123, specifies a control program suitable for washing the washing machine 200, and downloads the control program to the washing machine 200 (step S112). Thus, the CPU 210 of the washing machine 200 can further execute a washing process according to the downloaded control program, tailored to the user's preferences.

[0090] <Second Implementation>

[0091] In the above embodiment, when the set value reaches a limit, the server 100 extracts a control program suitable for the washing machine 200 and provides it to the washing machine 200. However, it is also possible to extract a washing control program suitable for the washing machine 200 and download it to the washing machine 200 regardless of whether the set value has reached a limit.

[0092] <Third Implementation Method>

[0093] In the above embodiment, feedback related to washing, detergent, or fabric softener information is input to the communication terminal 300, but this information can also be received by the washing machine 200 itself. For example, the CPU 210 can also obtain feedback related to washing, detergent, or fabric softener information via the operation unit 240 of the washing machine 200 and the reading sensor 282, and upload it to the server 100 via the communication interface 260.
