First Embodiment
<Overall configuration of network system>

First, the overall configuration of a network system 1 according to the present embodiment will be described with reference to Fig. 1. The network system 1 includes, as main devices, a server 100 for providing the present service, a plurality of washing machines 200 installed in each home that exchange data with the server 100 via a router, the Internet, etc., and a communication terminal 300 such as a smartphone of a user who uses the washing machines 200.
<Network system operation overview>

Next, an overview of the operation of the network system 1 according to this embodiment will be described with reference to Figures 1 to 3.

First, the user runs the washing machine 200 to wash the laundry. When the washing is finished, the washing machine 200 transmits a notification to that effect to the server 100. At this time, the washing machine 200 transmits various sensing result data measured during this washing to the server 100. For example, the steps performed, the amount of water used in each step, the time for each step, the amount of laundry, the degree of dirt, etc. are uploaded.

The server 100 transmits to the communication terminal 300 of the user of the washing machine 200 a notification that the wash is complete and a notification that feedback is being received. The communication terminal 300 receives feedback from the user regarding the current wash and transmits it to the server 100. The server 100 corrects various settings in the standard wash course of the washing machine 200 based on the feedback, and transmits the correction data to the washing machine 200. This allows the washing machine 200 to perform control that is more in line with the user's needs when executing the next standard wash course.

In this embodiment, after the feedback is provided to the server 100, the server 100 transmits a report on the sensing results for the current wash to the communication terminal 300. The communication terminal 300 displays the report on the sensing results.

In particular, in this embodiment, the server 100 downloads a washing control program to the washing machine 200 to perform control that is more in line with the user's needs, based on feedback input to the communication terminal 300 and the sensing results of the washing machine 200. For example, when a washing control program that is more in line with the user's needs is prepared, the server 100 inquires of the user's communication terminal 300 whether or not to download the control program to the washing machine 200. Then, when the server 100 receives an affirmative response from the user, it downloads the control program to the washing machine 200.

In this way, network system 1 according to the present embodiment provides washing machine 200 with a control program for performing washing that better meets the needs of the user, based on information input by the user to communication terminal 300 or washing machine 200, and sensing results of washing machine 200. The configuration of each device in the network system for realizing such functions will be described in detail below.
<Configuration of communication terminal 300>

First, one aspect of the configuration of the communication terminal 300 used by a user who uses the washing machine 200 will be described. The communication terminal 300 is a device capable of data communication with the server 100, such as a smartphone, a wearable device, a tablet, or a personal computer.

The display 330 outputs characters, images, etc. based on signals from the CPU 310. The operation unit 340 accepts commands from a user and inputs the commands to the CPU 310. The display 330 and the operation unit 340 may be realized by a touch panel 350.

The communication interface 360 is realized by a communication module such as a wireless LAN communication or a wired LAN. The communication interface 360 transmits and receives data to and from other devices such as the server 100 via wired or wireless communication.

The speaker 370 outputs audio based on a signal from the CPU 310. The microphone 380 creates an audio signal based on external audio and inputs it to the CPU 310.

In this embodiment, for example, the CPU 310 receives feedback on laundry from the user via the operation unit 340 based on instructions from the server 100 in accordance with the program in the memory 320, and transmits the feedback data to the server 100 via the communication interface 360. The feedback information may be received directly by the washing machine 200 via its own user interface.

5, in the present embodiment, CPU 310 receives information on the detergent and fabric softener to be put into washing machine 200 from the user via operation unit 340 in accordance with the program in memory 320, and transmits the information to server 100 via communication interface 360. Note that, as will be described later, information on the detergent and fabric softener used in washing machine 200 may also be acquired by washing machine 200.

The CPU 210 controls each part of the washing machine 200 by executing a program stored in the memory 220 or an external storage medium. For example, the CPU 110 controls the appliance driving unit 290 based on a control command for washing to perform a washing process, controls the appliance driving unit 290 based on a control command for drying to perform a drying process, and calculates the scheduled end time of the washing process.

Memory 220 is realized by various RAMs, various ROMs, etc. Memory 220 stores the washing control program, drying control program, dialogue program, and other programs executed by CPU 210, voice data and other data received from server 100 and other servers, data input via operation unit 240, and sensing results measured by various sensors 281. Note that memory 120 stores multiple washing control programs in advance, but as described below, new control programs suitable for washing machine 200 are downloaded and stored in memory 120 based on feedback data and sensing results.

For example, memory 220 stores the adjustment data shown in FIG. 7. The adjustment data stores, for example, the correspondence between adjustment items, adjustment values, and adjustment contents. More specifically, the correspondence between the adjustment values from server 100 and adjustment contents is stored for each item to be adjusted, such as water volume, washing time, number of spin cycles, and spin cycle time. For example, with regard to the water volume, when an adjustment value of 1 is provided from server 100, the water volume is corrected to 5 liters less than the standard, when an adjustment value of 2 is provided from server 100, the water volume is set to the standard, and when an adjustment value of 3 is provided from server 100, the water volume is corrected to 5 liters more than the standard.

Returning to FIG. 6, the display 230 outputs characters, images, and the like based on signals from the CPU 210. The operation unit 240 is realized by buttons, a touch panel, and the like, and receives various commands from the user and inputs the commands to the CPU 210.

The communication interface 260 is realized by a communication module such as wireless LAN communication or wired LAN, and exchanges data with other devices such as the server 100 via wired or wireless communication. For example, the CPU 210 transmits commands received via the operation unit 240, the scheduled end time of the wash, various sensing data measured during the wash, etc., to the server 100 via the communication interface 260, and receives adjustment values, control programs, remote control commands, and other data from the server 100 and inputs them to the CPU 210.

The speaker 270 outputs sound based on a signal from the CPU 210. For example, the CPU 210 outputs from the speaker 270 sound data that has been preregistered in the memory 220 or sound data received from the server 100.

The laundry sensor 281 measures the amount of water used, the weight of the laundry, whether the door is open or closed, the degree of dirt, etc., and inputs the measurement results to the CPU 210.

The reading sensor 282 is a camera, barcode reader, RFID antenna, etc., that reads the QR code (registered trademark) or barcode on the detergent or fabric softener packaging, obtains information about the detergent or fabric softener, and inputs it to the CPU 210.

The timer 285 inputs the current time to the CPU 210, and measures the time elapsed since the start of washing and the time until washing is completed, and inputs these values to the CPU 210.

The device driving unit 290 realizes the main functions of the washing machine 200, such as a motor, an actuator, and a heater. The CPU 210 controls the device driving unit 290 based on a control program prepared in advance to perform washing, or controls the device driving unit 290 based on a new control program downloaded from the server 100 based on feedback data and sensing results to perform washing.
<Configuration of Server 100>

Next, each device constituting the network system 1 will be described in detail. First, one aspect of the configuration of the server 100 will be described with reference to FIG. 8. The server 100 according to this embodiment includes, as its main components, a CPU (Central Processing Unit) 110, a memory 120, an operation unit 140, and a communication interface 160.

The CPU 110 controls each part of the server 100 by executing a program stored in the memory 120. For example, the CPU 110 executes a program stored in the memory 120 and performs various processes described below by referring to various data.

Memory 120 is realized by various RAMs, various ROMs, etc., and may be included in server 100, may be detachable from various interfaces of server 100, or may be a recording medium of another device accessible from server 100. Memory 120 stores programs executed by CPU 110, data generated by execution of programs by CPU 110, user information data 121, washing machine information data 122, program information data 123, feedback correspondence data, adjustment value limit correspondence data, adjustment value fluctuation correspondence data, detergent correspondence data, sensing result correspondence data, laundry left-out correspondence data, etc.

Referring to FIG. 9, the user information data 121 stores, for each user registered with this service, the correspondence between the user's identification information, user name, identification information of the user's communication terminal 300, the user's address, and user attributes such as age and gender.

Referring to FIG. 10, the washing machine information data 122 stores, for each washing machine 200 registered with this service, the correspondence between the identification information of the washing machine 200, the user of the washing machine 200, detergent information, fabric softener information, various histories such as the operation and sensing results of the washing machine 200, various adjustment values based on the feedback and sensing results, and information on the control program downloaded to the washing machine 200 based on the feedback and sensing results.

Referring to FIG. 11, the program information data 123 stores, for each control program used in the washing machine, a correspondence between the program identification information, the program contents and code, and the conditions suitable for providing the program to the washing machine 200.

Referring to FIG. 12, the feedback correspondence data stores the correspondence between adjustment items and adjustment values corresponding to feedback from the communication terminal 300.

Referring to FIG. 13, the adjustment value limit correspondence data stores, for each adjustment item, a guide message to be provided to the communication terminal 300 when the adjustment value reaches its limit. The adjustment value limit correspondence data also stores information on a control program that is preferably downloaded to the washing machine 200, in association with the adjustment item and the limit value of the adjustment value. When the situation cannot be addressed by simply changing the adjustment value of the standard washing course, the CPU 110 provides the washing machine 200 with a new control program via the communication interface 160. For example, a control program may be prepared that uses more water than the standard washing course, extends the washing time, or increases the number of washes, or that reduces the number of rotations of the washing layer and the amount of detergent compared to the standard washing course.

Referring to FIG. 14, the adjustment value fluctuation correspondence data stores a guide message to be provided to the communication terminal 300 when the feedback fluctuates. The adjustment value fluctuation correspondence data also stores information on a control program that is preferably downloaded to the washing machine 200 in association with the repetition of conflicting feedback. Then, when the problem cannot be solved by simply changing the adjustment value of the standard washing course, the CPU 110 provides the washing machine 200 with a new control program via the communication interface 160.

Referring to FIG. 15, the detergent correspondence data stores the correspondence between detergents and fabric softeners and the guide text. The detergent correspondence data also stores information on a control program that is preferably downloaded to the washing machine 200 in correspondence with the detergent, fabric softener, or a combination thereof. Specifically, it is preferable to create the detergent correspondence data by acquiring the preferred correspondence between the amount of laundry, the amount of detergent or fabric softener, the wash time, and the amount of water from a server of the detergent or fabric softener manufacturer. Then, according to the information on the specified detergent or fabric softener, the CPU 110 creates a preferred control program for the amount of laundry, the amount of detergent or fabric softener, the wash time, and the amount of water, or a control program of a level that cannot be handled by feedback, and provides it to the washing machine 200.

Referring to FIG. 16, the sensing result correspondence data stores the correspondence between the sensing result by the washing machine 200 and the guidance text. The sensing result correspondence data also stores information on a control program that is preferably downloaded to the washing machine 200 in association with the sensing result. Specifically, when a large amount of dirt is detected, a control program that uses a larger amount of detergent or a control program with a longer wash time is created, and when it is detected that detergent foam is not easily eliminated, a control program with a longer rinse time or number of rinses is created, or a control program of a level that cannot be handled by feedback is created and provided to the washing machine 200.

Referring to FIG. 17, the laundry-leaving corresponding data stores the correspondence between the adjustment value, the time the laundry is left lying around from the end of washing to the opening of the door, and the guide message. The laundry-leaving corresponding data also stores information on a control program that is preferably downloaded to the washing machine 200 in association with the notification time. Specifically, for washing machine 200 that is left lying around for a long time on average, a control program that uses a larger amount of antibacterial detergent, a control program that uses LED lights, a control program that uses the air blowing function for a longer period, or a control program at a level that cannot be handled by feedback may be created and provided to washing machine 200.

Returning to FIG. 8, the operation unit 140 accepts operations from a service administrator or the like and inputs various commands to the CPU 110.

Communication interface 160 transmits various data such as voice data and control commands to other devices such as washing machine 200 and communication terminal 300 via the Internet, a carrier network, a router, etc. Conversely, communication interface 160 receives data from other devices via the Internet, a carrier network, a router, etc., and passes the data to CPU 110.
