[First embodiment]
A washing machine system 1 according to a first embodiment of the present invention will be described with reference to Fig. 1. Fig. 1 is a schematic diagram of the washing machine system 1 according to the first embodiment of the present invention.

As shown in FIG. 1, the washing machine system 1 includes a washing machine 100 and a server 200. The washing machine 100 and the server 200 can communicate with each other via a communication network N that uses, for example, an electrical communication network or an optical communication network.

The washing machine 100 includes an operation display unit 110, a connection port 111, a door 112, a door open button 113, and a housing 114.

The operation display unit 110 is provided at the top of the front surface of the housing 114. The connection port 111 is provided at the top of the front surface of the housing 114. The connection port 111 is connected to a water faucet. Water released from the faucet is supplied to the washing machine 100 via the connection port 111. The door 112 is provided at the front surface of the housing 114. The door 112 separates the inside of the housing 114 from the outside of the housing 114. The door open button 113 is located around the periphery of the door 112. When the door open button 113 is operated, the door 112 opens.

Next, the washing machine 100 will be further described with reference to Figure 2. Figure 2 is a cross-sectional view of the washing machine 100.

As shown in FIG. 2, the washing machine 100 further includes a drum 115, a water tub 116, and a damper 117.

The drum 115 and the water tub 116 are each disposed inside the housing 114. The drum 115 and the water tub 116 each have a cylindrical shape with one end closed. The drum 115 is capable of holding laundry. A drum bottom is formed at one end of the drum 115. A drum opening 15a is formed at the other end of the drum 115. The drum opening 15a faces the door 112. The drum 115 is disposed inside the water tub 116. A water tub bottom is formed at one end of the water tub 116. A water tub opening 16a is formed at the other end of the water tub 116. The water tub opening 16a faces the door 112.

When the door 112 is opened, the drum opening 15a faces the outside of the housing 114. As a result, the user can load laundry into the drum 115 through the drum opening 15a.

The washing machine 100 further includes a drum motor 118, an output shaft 119, a plurality of holes 120, and a plurality of baffles 121.

The drum motor 118 rotates the drum 115. The drum motor 118 is connected to the drum 115 via an output shaft 119. A plurality of holes 120 are formed in the drum 115. The plurality of holes 120 penetrate the drum 115. Each of the plurality of baffles 121 is formed on the inner circumferential surface of the drum 115 and protrudes inward from the drum 115. The plurality of baffles 121 are arranged along the circumferential direction of the drum 115.

The steps for the washing machine 100 to perform a wash operation are explained below.

First, laundry is placed into the drum 115. Water is then supplied into the drum 115 through multiple holes 120, and the laundry is immersed in the water. The drum 115 is then rotated by the power of the drum motor 118. As the drum 115 rotates, the laundry is lifted by the baffle 121. The laundry then falls due to gravity and is slammed against the inner surface of the drum 115. As the drum 115 continues to rotate, the laundry is alternately lifted and slammed against the inner surface of the drum 115. As a result, the laundry is washed.

The washing machine 100 further includes a fan 122, a heater 123, and a duct 124. The fan 122 is connected to the drum 115 via the heater 123 and the duct 124.

The procedure for the washing machine 100 to perform the drying operation is explained below.

Hot air generated by the fan 122 and heater 123 is supplied to the inside of the water tub 116 via the duct 124. The hot air supplied to the inside of the water tub 116 is then supplied to the inside of the drum 115 via multiple holes 120. As a result, the laundry inside the drum 115 is dried.

The washing machine 100 washes and dries laundry by performing, for example, a washing process, a rinsing process, a spin-drying process, and a drying process. The washing process refers to the process of washing laundry. The rinsing process refers to the process of rinsing laundry. The spin-drying process refers to the process of spin-drying laundry. The drying process refers to the process of drying laundry. Note that the washing machine 100 does not necessarily have a drying function.

Hereinafter, the operation details of the washing machine 100 may be referred to as "operation details."

In the first embodiment, the washing machine 100 has multiple operation settings. Each operation setting is associated with an operation content.

In the first embodiment, the multiple operation settings include "low vibration," "standard," and "smooth," which indicate settings for the "spin-dry level." The multiple operation settings also include "thorough," "standard," and "moderate," which indicate settings for the "dry level." The multiple operation settings also include "standard," "thorough," and "dry," which indicate settings for the "washing course" and "wash-to-dry course." Operation settings created by the user are registered under each of "My Way" and "Original." The "washing course" refers to a course that includes a washing process, a rinsing process, and a spin-drying process. The "washing-to-dry course" refers to a course that includes a drying process in addition to the "washing course."

The unlock key 513 accepts an instruction to unlock the door 112. The power on key 514 accepts an instruction to start the flow of electricity to the washing machine 100. The power on key 514 is an example of a power operation unit of the present invention. The power off key 515 accepts an instruction to cut off the flow of electricity to the washing machine 100.

Next, the washing machine 100 will be further described with reference to Figure 4. Figure 4 is a block diagram of the washing machine 100.

As shown in FIG. 4, the washing machine 100 further includes an output unit 125, a washing machine communication unit 126, a washing machine memory unit 127, and a washing machine control device 128.

The output unit 125 outputs sound. The output unit 125 includes, for example, a speaker. The washing machine communication unit 126 is a device that communicates with the server 200. The washing machine communication unit 126 communicates with the server 200, for example, via a wireless access point and communication network N (see FIG. 1). In this case, the washing machine communication unit 126 communicates with the wireless access point using, for example, the Wi-Fi (registered trademark) communication standard.

The washing machine memory unit 127 includes a main memory device (e.g., semiconductor memory) such as ROM (Read Only Memory) and RAM (Random Access Memory), and may further include a secondary memory device (e.g., a hard disk drive). The washing machine memory unit 127 stores various computer programs executed by the washing machine control device 128.

The washing machine memory unit 127 stores correspondence information Y. Correspondence information Y will be explained later.

The washing machine control device 128 includes a processor such as a CPU (Central Processing Unit) and an MPU (Micro Processing Unit). The washing machine control device 128 controls each element of the washing machine 100. Specifically, the processor of the washing machine control device 128 controls the operation display unit 110, drum motor 118, fan 122, heater 123, output unit 125, washing machine communication unit 126, and washing machine memory unit 127 by executing a computer program stored in the washing machine memory unit 127.

The washing machine control device 128 has a washing machine control unit 128a and a determination unit 128b. Specifically, the processor of the washing machine control device 128 executes a computer program stored in the washing machine memory unit 127, thereby functioning as the washing machine control unit 128a and the determination unit 128b.

Next, we will explain correspondence information Y with reference to Figures 3 and 5. Figure 5 shows correspondence information Y.

As shown in Figures 3 and 5, the correspondence information Y indicates information that associates operation settings with the operation details of the washing machine 100. When an operation setting is selected via the selection receiving unit X, the washing machine control unit 128a determines the operation details of the washing machine 100 associated with the operation setting based on the correspondence information Y. As a result, the washing machine 100 operates according to the operation details associated with the operation setting in the correspondence information Y.

For example, the operation settings specified for "My Way" are associated with a specific washing machine 100 operation in the correspondence information Y. The specific washing machine 100 operation is an operation in which the washing process takes α1 minute, the number of rinse cycles is α2, and the spin cycle takes α3 minutes. In this case, when "My Way" is selected via the selection receiving unit X, the washing machine 100 will perform the washing process for α1 minute, the rinsing process α2 times, and the spin cycle for α3 minutes.

Next, the server 200 will be described with reference to Figure 6. Figure 6 is a block diagram showing the server 200.

As shown in FIG. 6, server 200 may be a switch, a server cluster consisting of multiple servers, or a cloud computing service center. Server 200 provides communication services to clients.

The server 200 includes a server communication unit 210, a server storage unit 211, and a server control unit 212.

The server communication unit 210 is a device that communicates with the washing machine 100. The server communication unit 210 communicates with the server 200, for example, via a wireless access point and the communication network N.

The server memory unit 211 includes main memory devices such as ROM and RAM, and may also include auxiliary memory devices. The server memory unit 211 stores various computer programs executed by the server control unit 212.

The server storage unit 211 is capable of storing recommendation information 21a and registration information 21b. Therefore, the server storage unit 211 stores recommendation information 21a and registration information 21b.

Recommendation information 21a includes recommended operation settings for washing machine 100. In detail, recommendation information 21a includes information that associates recommended operation settings for washing machine 100 with the operation details of washing machine 100. Hereinafter, recommended operation settings for washing machine 100 may be referred to as recommended operation settings.

The administrator of the server 200 determines the recommended operating settings.

The server control unit 212 may also determine the recommended operation settings. In this case, for example, the server control unit 212 acquires the operation settings used by each of the multiple washing machines 100 from the multiple washing machines 100, and determines the recommended operation settings based on the acquired operation settings. For example, the server control unit 212 determines a ranking of the number of times the operation settings acquired from the multiple washing machines 100 have been used, and determines the operation setting with the highest ranking, or an operation setting higher than a predetermined rank, as the recommended operation setting.

The recommended operation settings stored in the server storage unit 211 may be single or multiple. If the server storage unit 211 stores multiple recommended operation settings, priorities may be set for the multiple recommended operation settings in the order in which they are recommended to the washing machine 100.

Registration information 21b contains the same content as correspondence information Y (see FIG. 5). Server 200 communicates with washing machine 100 via communication network N to obtain correspondence information Y from washing machine 100 and generate registration information 21b. As a result, server 200 can determine the operation settings registered in washing machine 100 from registration information 21b.

The server control unit 212 includes a processor such as a CPU and an MPU. The server control unit 212 controls each element of the server control unit 212. Specifically, the processor of the server control unit 212 controls the server communication unit 210 and the server storage unit 211 by executing a computer program stored in the server storage unit 211.

Next, the first operation of washing machine system 1 will be described with reference to Figures 7 to 9. Figure 7 is a first flow diagram showing the first operation of washing machine system 1. Figure 8 is a second flow diagram showing the first operation of washing machine system 1. Figure 9 is a schematic diagram showing the first operation of washing machine system 1.

As shown in Figures 7 and 9, in the first embodiment, the recommended operation setting A1 and the operation content A2 of the washing machine 100 associated with the recommended operation setting A1 are pre-registered in the washing machine 100. In other words, the recommended operation setting A1 and the operation content A2 of the washing machine 100 associated with the recommended operation setting A1 are stored in the washing machine memory unit 127.

Note that operation setting A1 being pre-registered in washing machine 100 means that operation setting A1 is stored in washing machine storage unit 127 before the trigger operation shown in step S100 below is performed, and operation setting A1 can be selected via selection receiving unit X (see FIG. 3). For example, the default operation setting registered in washing machine 100 when washing machine 100 is manufactured corresponds to the operation setting pre-registered in washing machine 100.

The first operation is described below.

In step S100, the determination unit 128b determines whether a trigger operation has been performed. A trigger operation refers to an operation that triggers the washing machine 100 to send an inquiry communication to the server 200. The inquiry communication refers to communication to inquire about the presence or absence of recommended operation settings. The trigger operation is performed via the trigger operation unit.

The trigger operation unit in the first embodiment simultaneously accepts a trigger operation and an instruction to the washing machine 100. Therefore, even if the user inputs an instruction to the washing machine 100 via the trigger operation unit without being aware of the trigger operation, the determination unit 128b determines that a trigger operation has been performed. As a result, inquiry communication is initiated, allowing the user to recognize that the washing machine 100 has the function of communicating with the server 200.

In the first embodiment, the trigger operation unit is the power-on key 514. In this case, the trigger operation refers to the operation of the power-on key 514. When the power-on key 514 is operated and the power of the washing machine 100 is turned on from off, the determination unit 128b determines that a trigger operation has been performed.

Note that the trigger operation unit is not limited to the power-on key 514. A key on the reception unit 50 other than the power-on key 514 may also be the trigger operation unit.

The washing machine 100 may also be provided with an open/close detection unit that detects whether the door 112 is open or closed, and the open/close detection unit may function as a trigger operation unit. For example, after the power-on key 514 is operated to start the washing machine 100, when the open/close detection unit first detects that the door 112 has been opened, the determination unit 128b determines that a trigger operation has been performed.

Furthermore, the washing machine 100 may be provided with a voice reception device, such as a microphone, that receives voice, and the voice reception device may function as the trigger operation unit. For example, when a specific voice is input via the voice reception device, the determination unit 128b determines that a trigger operation has been performed.

Furthermore, the washing machine 100 may be provided with a human presence sensor, which functions as the trigger operation unit. For example, after the power-on key 514 is operated to start the washing machine 100, when the human presence sensor first detects a person, the determination unit 128b determines that a trigger operation has been performed.

If a trigger operation is performed (Yes in step S100), processing proceeds to step S110. If a trigger operation is not performed (No in step S100), the processing shown in step S100 is repeated.

In step S110, the washing machine control unit 128a controls the washing machine communication unit 126 so that the washing machine communication unit 126 sends trigger information to the server 200. The trigger information includes information indicating that the server 200 is to be queried as to whether or not there are any recommended operation settings.

In step S200, the server communication unit 210 receives trigger information.

In step S210, the server control unit 212 determines whether there are any recommended operation settings. Specifically, the server control unit 212 determines whether recommended information 21a is stored in the server storage unit 211.

If a recommended operating setting is available (Yes in step S210), processing proceeds to step S220. In the first embodiment, the recommended operating setting is operating setting A1.

If there are no recommended operating settings (No in step S210), processing proceeds to step S230.

In step S220, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 sends first query information to the washing machine 100. The first query information is information indicating whether or not to use the recommended operation setting A1.

The first query information is an example of query information of the present invention.

In step S230, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 transmits termination information to the washing machine 100. The termination information is information indicating that the server 200 has terminated the process for notifying the washing machine 100 of recommended operation settings. As a result, the processing of the server 200 terminates.

In step S120, the washing machine control unit 128a determines whether the washing machine communication unit 126 has received the first query information.

If the washing machine communication unit 126 receives the first query information (Yes in step S120), processing proceeds to step S130.

If the washing machine communication unit 126 does not receive the first query information (No in step S120), the processing of the washing machine 100 ends. In other words, if the washing machine communication unit 126 receives termination information, the processing of the washing machine 100 ends.

In step S130, the washing machine control unit 128a controls the output unit 125 so that the output unit 125 outputs the first query information. The output unit 125 outputs the first query information by voice.

An example of the first question information is, "It looks like it will start raining in an hour. Would you like to add drying to the wash settings?" In this case, the recommended operation setting A1 prepared by the server 200 is, for example, "Standard" for the "Wash-Dry Course."

Two examples of the first question information are, "It's gotten colder recently, and it seems like the laundry isn't drying as well. Would you like to set it to thorough drying?" In this case, the recommended operation setting A1 prepared by the server 200 is, for example, "thorough" for the "drying level."

Note that while the output unit 125 is outputting the first query information by voice, operation of all keys included in the reception unit 50 may be disabled. Also, while the output unit 125 is outputting the first query information by voice, the light-emitting units of multiple keys (bath water key 501 to listen key 518) on the reception unit 50 may be turned off. As a result, it is possible to prevent erroneous operation by the user.

The output unit 125 provided in the washing machine 100 may also be a display device such as a monitor. In this case, the first query information is displayed on the display device. As a result, the user can visually recognize the first query information via the display device.

As shown in FIG. 8, in step S140, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the first question within a predetermined time period. In the first embodiment, the wash key 503 and the dry key 506 of the reception unit 50 receive responses to the first question. The wash key 503 functions as a key that accepts "Yes." In the first embodiment, the wash key 503 accepts a response that indicates that the recommended operation setting A1 will be used. The dry key 506 functions as a key that accepts "No." In the first embodiment, the dry key 506 accepts a response that indicates that the recommended operation setting A1 will not be used.

The specified time is set in advance and stored in the washing machine memory unit 127.

In addition, within a predetermined time, the illuminated area around the wash key 503 that is shaped like the word "Yes" may be illuminated, and the illuminated area around the dry key 506 that is shaped like the word "No" may be illuminated. As a result, the user can easily enter a response to the first question.

Furthermore, the washing machine 100 may be equipped with a voice receiving device, such as a microphone, that receives voice, and the voice receiving device may receive a voice response to the first question.

The wash key 503 and dry key 506 are examples of the response receiving unit of the present invention.

If the reception unit 50 receives a response to the first question within the specified time (Yes in step S140), processing proceeds to step S150.

If the reception unit 50 does not receive a response to the first question within the specified time (No in step S140), the processing of the washing machine 100 ends.

In step S150, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the first question indicating that the recommended operation setting A1 will be used. In other words, in step S140, the washing machine control unit 128a determines whether the wash key 503 (Yes) has been operated.

If the wash key 503 is operated and a response indicating that the recommended operation setting A1 will be used is entered (Yes in step S150), processing proceeds to step S160.

If the drying key 506 is operated and a response is entered indicating that the recommended operation setting A1 will not be used (No in step S150), the processing of the washing machine 100 ends.

In step S160, the washing machine control unit 128a uses the recommended operation setting A1. Using the recommended operation setting A1 means that the washing machine control unit 128a operates the washing machine 100 in accordance with the operation content A2 of the washing machine 100 associated with the recommended operation setting A1.

When the first query information is an example, the recommended operation setting A1 is "standard" for the "wash-dry course." Therefore, when the first query information is an example, the washing machine control unit 128a uses operation setting A1 that sets the "wash-dry course" to "standard."

When the first question information is Example 2, the recommended operation setting A1 is "thorough" for the "drying level." Therefore, when the first question information is Example 2, the washing machine control unit 128a uses the operation setting A1 that sets the "drying level" to "thorough." For example, when the user uses the operation setting "standard" for the "wash-dry course," the washing machine control unit 128a enables the use of the operation setting A1 that sets the "drying level" to "thorough." Then, the washing machine control unit 128a adds the operation setting A1 that sets the "drying level" to "thorough" to the operation settings used by the user.

As described above with reference to Figures 7 to 9, in step S220 (see Figure 7), the server communication unit 210 sends first question information to the washing machine 100. Therefore, a user who is unfamiliar with the types of operation settings can respond that they will use the recommended operation setting A1. In contrast, a user who wants to select the operation setting themselves can respond that they will not use the recommended operation setting A1. As a result, the washing machine system 1 can allow the user to select an operation setting that suits the user's needs for the task of selecting the operation setting for the washing machine 100.

Furthermore, in step S130, the output unit 125 outputs the first query information. Therefore, the user can recognize that the washing machine system 1 has a function to notify the user of the recommended operation setting A1. Furthermore, the user can be provided with an opportunity to learn about the operation setting A1 that he or she was not previously aware of.

Furthermore, in step S150 (see Figure 8), the user responds by indicating that they wish to use the recommended operation setting A1, which results in the operation setting A1 being selected. This eliminates the need for the user to search for the operation setting A1 they wish to use. As a result, operation setting A1 can be easily selected, allowing for efficient laundry operations.

Furthermore, in step S150, a response to the first question is input via keys provided on the washing machine 100 (in the first embodiment, the wash key 503 and the dry key 506). Therefore, there is no need to provide a separate device for inputting a response to the first question. As a result, a response to the first question can be easily input.

Second Embodiment
Next, a second operation of washing machine system 1 will be described with reference to Fig. 10 to Fig. 14. Fig. 10 is a flow chart showing the second operation of washing machine system 1. Fig. 11 is a first schematic diagram showing the second operation of washing machine system 1.

As shown in Figures 10 and 11, the second embodiment differs from the first embodiment in that the recommended operation setting C1 is not registered in the washing machine 100. The fact that the operation setting C1 is not registered in the washing machine 100 means that the operation setting C1 is not stored in the washing machine memory unit 127, and the operation setting C1 cannot be selected via the selection receiving unit X (see Figure 3).

The following describes the second operation of the washing machine system 1, focusing mainly on the differences from the first operation of the first embodiment.

In step S211, the server control unit 212 determines whether there are any recommended driving settings.

If a recommended operating setting is available (Yes in step S211), processing proceeds to step S221. In the second embodiment, the recommended operating setting is operating setting C1.

If there are no recommended operating settings (No in step S211), processing proceeds to step S230.

In step S221, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 sends second query information to the washing machine 100. The second query information is information indicating whether or not to use the recommended operation setting C1.

The second query information is an example of query information of the present invention.

In step S121, the washing machine control unit 128a determines whether the washing machine communication unit 126 has received the second query information.

If the washing machine communication unit 126 receives the second query information (Yes in step S121), processing proceeds to step S131.

If the washing machine communication unit 126 does not receive the second query information (No in step S121), the processing of the washing machine 100 ends. In other words, if the washing machine communication unit 126 receives the termination information, the processing of the washing machine 100 ends.

In step S131, the washing machine control unit 128a controls the output unit 125 so that the output unit 125 outputs the second query information.

An example of the second question information is, "Dad did the laundry over the weekend, but would you like to return to Mom's laundry settings today?" In this case, the recommended operation setting C1 prepared by the server 200 is, for example, "Mom's laundry," which can be registered under "Our Way."

Two examples of the second question information are, "It's the season when you need a blanket. Why not wash your blanket using the dust mite removal cycle before using it?" In this case, the recommended operating setting C1 prepared by the server 200 is, for example, the "dust mite removal cycle," which can be registered as "original."

In step S141, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the second question within a predetermined time period.

If the reception unit 50 receives a response to the second question within the specified time (Yes in step S141), processing proceeds to step S170.

If the reception unit 50 does not receive a response to the second question within the specified time (No in step S141), the processing of the washing machine 100 ends.

In step S170, the washing machine 100 performs a first response transmission process.

Furthermore, after the processing shown in step S221 is completed, in step S240, the server 200 performs a first response reception process. A detailed description of the first response process will be provided later with reference to Figures 13 and 14.

The first response transmission process will be described with reference to Figures 12 and 14. Figure 12 is a flow diagram showing the first response transmission process. Figure 14 is a second schematic diagram showing the second operation of the washing machine system 1.

As shown in Figures 12 and 14, in step S171, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the second question indicating that the recommended operation setting C1 will be used.

If the reception unit 50 receives a response indicating that the recommended operation setting C1 will be used (Yes in step S171), processing proceeds to step S172.

If the reception unit 50 does not receive a response indicating that the recommended operation setting C1 will be used (No in step S171), processing proceeds to step S176.

In step S172, the washing machine control unit 128a controls the washing machine communication unit 126 so that the washing machine communication unit 126 sends first consent information to the server 200. The first consent information is a response indicating that the washing machine 100 will use the recommended operation setting C1.

In step S173, the washing machine communication unit 126 receives information indicating the recommended operation setting C1 from the server 200. In detail, the washing machine communication unit 126 receives recommendation information 21a from the server 200. The recommendation information 21a includes an operation setting C1 indicating the recommended operation setting and operation content C2 indicating the operation content of the washing machine 100 associated with the recommended operation setting.

In step S174, the washing machine control unit 128a uses the recommended operation setting C1.

When the second query information is an example, the recommended operation setting C1 is "Mom's Laundry." Therefore, when the second query information is an example, in step S173, the washing machine communication unit 126 receives from the server 200 information indicating "Mom's Laundry" and information indicating the operation details of the washing machine 100 associated with "Mom's Laundry." Then, in step S174, the washing machine control unit 128a uses the operation setting C1 for "Mom's Laundry."

When the second query information is two examples, the recommended operation setting C1 is the "Mite-free course." Therefore, when the second query information is two examples, in step S173, the washing machine communication unit 126 receives from the server 200 information indicating the "Mite-free course" and information indicating the operation details of the washing machine 100 associated with the "Mite-free course." Then, in step S174, the washing machine control unit 128a uses the operation setting C1 for the "Mite-free course."

In step S175, the washing machine control unit 128a registers the recommended operation setting C1 in the washing machine 100. In detail, the washing machine control unit 128a stores correspondence information Y, which is composed of the recommended operation setting C1 and the operation content C2 of the washing machine 100 that corresponds to the recommended operation setting C1, in the washing machine memory unit 127. As a result, it becomes possible to select the recommended operation setting C1 via the selection receiving unit X.

When the washing machine control unit 128a registers the recommended operation setting C1 in the washing machine 100, the processing of the washing machine 100 ends.

In step S176, the washing machine control unit 128a controls the washing machine communication unit 126 so that the washing machine communication unit 126 sends first refusal information to the server 200. The first refusal information is a response indicating that the washing machine 100 will not use the recommended operation setting C1. As a result, the processing of the washing machine 100 ends.

The first response reception process will be explained with reference to Figures 13 and 14. Figure 13 is a flow diagram showing the first response reception process.

As shown in Figures 13 and 14, in step S241, the server control unit 212 determines whether the server communication unit 210 has received the first consent information transmitted from the washing machine 100 in step S172 (see Figure 10).

If the server communication unit 210 receives the first consent information (Yes in step S241), processing proceeds to step S242.

If the server communication unit 210 does not receive the first consent information (No in step S241), the processing of the server 200 ends. In other words, if the server communication unit 210 does not receive the first refusal information, the processing of the server 200 ends.

In step S242, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 transmits information indicating the recommended operation setting C1. In particular, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 transmits recommendation information 21a to the washing machine 100. As a result, in step S173 (see FIG. 12), the washing machine 100 receives information indicating the recommended operation setting C1 and information indicating the operation content C2.

In step S243, the server control unit 212 updates the registration information 21b (see FIG. 6). In particular, information indicating the recommended operation setting C1 and the operation content C2 of the washing machine 100 associated with the recommended operation setting C1 are added to the registration information 21b. As a result, the processing of the server 200 ends.

As described above with reference to Figures 10 to 14, in step S221 (see Figure 10), the server communication unit 210 sends second question information to the washing machine 100. Therefore, the user can select "Yes" or "No" as the answer to the second question. As a result, the washing machine system 1 can allow the user to select operation settings according to the user's needs for the task of selecting operation settings for the washing machine 100.

Furthermore, in step S175 (see FIG. 12), the washing machine control unit 128a registers the recommended operation setting C1 in the washing machine 100. Therefore, after the operation setting C1 is registered in the washing machine 100, the user can select the operation setting C1 without the washing machine 100 communicating with the server 200.

[Third embodiment]
Next, a third operation of washing machine system 1 will be described with reference to Fig. 15 to Fig. 19. Fig. 15 is a flow chart showing the third operation of washing machine system 1. Fig. 16 is a first schematic diagram showing the third operation of washing machine system 1.

The third embodiment differs from the second embodiment in that the operation setting A1 registered in the washing machine 100 is updated.

As shown in Figures 15 and 16, in the third embodiment, a recommended operation setting A1 is registered in the washing machine 100. Hereinafter, the operation setting A1 registered in the washing machine 100 may be referred to as the registered operation setting A1. The operation content A2 of the washing machine 100 associated with the registered operation setting A1 is different from the operation content A3 of the washing machine 100 associated with the recommended operation setting A1.

In the third operation of the washing machine system 1, the registered operation setting A1 is updated to the recommended operation setting A1. Updating the registered operation setting A1 to the recommended operation setting A1 means that the operation content A2 associated with the registered operation setting A1 is changed to the operation content A3 associated with the recommended operation setting A1 (see FIG. 19).

The recommended operation setting A1 in the third embodiment is an example of an updated operation setting of the present invention.

The following describes the third operation of the washing machine system 1, focusing mainly on the differences from the second operation of the second embodiment.

As shown in Figures 15 and 16, in step S212, the server control unit 212 determines whether there are any recommended driving settings.

If a recommended operating setting is available (Yes in step S212), processing proceeds to step S222. In the second embodiment, the recommended operating setting is operating setting C1.

If there are no recommended operating settings (No in step S212), processing proceeds to step S230.

In step S222, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 sends third query information to the washing machine 100. The third query information is information indicating whether or not to use the recommended operation setting A1.

In the third embodiment, using the recommended operating setting A1 means updating the registered operating setting A1 to the recommended operating setting A1. Therefore, in the third embodiment, the third question information asks whether to update the registered operating setting A1 to the recommended operating setting A1.

The third query information is one of three examples of query information of the present invention.

In step S122, the washing machine control unit 128a determines whether the washing machine communication unit 126 has received the third query information.

If the washing machine communication unit 126 receives the third query information (Yes in step S122), processing proceeds to step S132.

If the washing machine communication unit 126 does not receive the third query information (No in step S122), the processing of the washing machine 100 ends. In other words, if the washing machine communication unit 126 receives the termination information, the processing of the washing machine 100 ends.

In step S132, the washing machine control unit 128a controls the output unit 125 so that the output unit 125 outputs the third query information.

An example of the third question information is, "The shirt washing method for washing shirts has been updated. Would you like to update to the latest recommended settings?" In this case, in the washing machine 100, the "shirt washing method," which is registered operation setting A1, is registered in "Original."

In step S142, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the third question within a predetermined time period.

If the reception unit 50 receives a response to the third question within the specified time (Yes in step S142), processing proceeds to step S180.

If the reception unit 50 does not receive a response to the third question within the specified time (No in step S142), the processing of the washing machine 100 ends.

In step S180, the washing machine 100 performs a second response transmission process.

Furthermore, after the processing shown in step S222 is completed, in step S250, the server 200 performs a second response reception process. A detailed description of the second response reception process will be provided later with reference to Figures 18 and 19.

The second response transmission process will be described with reference to Figures 17 and 19. Figure 17 is a flow diagram showing the second response transmission process. Figure 19 is a second schematic diagram showing the third operation of the washing machine system 1.

As shown in Figures 17 and 19, in step S181, the washing machine control unit 128a determines whether the reception unit 50 has received a response to the third question indicating that the registered operation settings A1 of the washing machine 100 should be updated to the recommended operation settings A1.

If the reception unit 50 receives a response indicating that the registered operation setting A1 of the washing machine 100 will be updated (Yes in step S181), the process proceeds to step S182.

If the reception unit 50 does not receive a response indicating that the registered operation setting A1 of the washing machine 100 will not be updated (No in step S181), the process proceeds to step S185.

In step S182, the washing machine control unit 128a controls the washing machine communication unit 126 so that the washing machine communication unit 126 sends second consent information to the server 200. The second consent information is a response indicating that the registered operation setting A1 of the washing machine 100 will be updated.

In step S183, the washing machine communication unit 126 receives update information from the server 200. The update information includes information indicating the operation content A3 associated with the recommended operation setting A1.

In step S184, the washing machine control unit 128a updates the registered operation setting A1 registered in the washing machine 100 to the recommended operation setting A1. In detail, the washing machine control unit 128a changes the operation content A2 of the washing machine 100 associated with the registered operation setting A1 to the operation content A3.

The washing machine control unit 128a stores the recommended operation setting A1 in the washing machine memory unit 127. As a result, when the recommended operation setting A1 is selected via the selection receiving unit X, the washing machine 100 operates according to the operation content A3.

As an example of the third question information, the "Shirt washing method" registered in the "Original" section of the washing machine 100 is updated.

When the washing machine control unit 128a updates the registered operation setting A1, the processing of the washing machine 100 ends.

In step S185, the washing machine control unit 128a controls the washing machine communication unit 126 so that the washing machine communication unit 126 sends second refusal information to the server 200. The second refusal information is a response indicating that the registered operation setting A1 of the washing machine 100 will not be updated. As a result, the processing of the washing machine 100 ends.

As shown in FIG. 15, after the processing shown in step S222 is completed, in step S250, the server 200 performs a second response reception process.

The second response reception process will be explained with reference to Figures 18 and 19. Figure 18 is a flow diagram showing the second response reception process.

As shown in Figures 18 and 19, in step S251, the server control unit 212 determines whether the server communication unit 210 has received the second consent information transmitted from the washing machine 100 in step S182 (see Figure 17).

If the server communication unit 210 receives the second consent information (Yes in step S251), processing proceeds to step S252.

If the server communication unit 210 does not receive the second consent information (No in step S251), the processing of the server 200 ends. In other words, if the server communication unit 210 does not receive the second refusal information, the processing of the server 200 ends.

In step S252, the server control unit 212 controls the server communication unit 210 so that the server communication unit 210 transmits the update information. As a result, in step S183 (see FIG. 17), the washing machine 100 receives the update information.

In step S253, the server control unit 212 updates the registration information 21b. Specifically, in the registration information 21b, operation content A2 associated with operation setting A1 is changed to operation content A3. As a result, the processing of the server 200 ends.

As described above with reference to Figures 15 to 19, in step S222 (see Figure 15), the server communication unit 210 sends third question information to the washing machine 100. Therefore, the user can select either Yes or No as the answer to the third question. As a result, the washing machine system 1 allows the user to select whether or not to update the registered operation setting A1.

Furthermore, in step S184 (see FIG. 17), the washing machine control unit 128a updates the registered operation setting A1 to the recommended operation setting A1. Therefore, after the recommended operation setting A1 is registered in the washing machine 100, the user can select the recommended operation setting A1 without the washing machine 100 communicating with the server 200.

Embodiments of the present invention have been described above with reference to the drawings (Figs. 1 to 19). However, the present invention is not limited to the above embodiments and can be implemented within the scope of its gist (e.g., (1) to (13)). Furthermore, various inventions can be created by appropriately combining multiple components disclosed in the above embodiments. For example, some components may be omitted from all components shown in the embodiments. The drawings primarily show each component diagrammatically to facilitate understanding, and the number of components shown may differ from the actual number due to the convenience of the drawings. Furthermore, the components shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within the scope of the invention without substantially departing from the effects of the present invention.

(1) In step S100 of the first to third embodiments (see Figures 7, 10, and 15), trigger operation is performed via the trigger operation unit.

The trigger operation unit may be a terminal such as a smartphone or a PC (Personal Computer). In this case, when an input unit such as a touch panel or keyboard provided on the terminal is operated, the determination unit 128b (see FIG. 4) determines that a trigger operation has been performed. The terminal is connected wirelessly or via a wired connection to the washing machine 100 and/or the server 200 so as to be able to communicate with them.

(2) In step S220 of the first embodiment (see FIG. 7), step S221 of the second embodiment (see FIG. 10), and step S222 of the third embodiment (see FIG. 15), the server communication unit 210 transmits query information to the washing machine 100. Query information is a general term for the first query information, the second query information, and the third query information. However, the present invention is not limited to this. The server communication unit 210 may transmit query information to the washing machine 100 and/or a terminal.

When the server communication unit 210 transmits query information to the terminal, the terminal receives the query information. The terminal then displays the query information on a terminal display unit provided on the terminal. The terminal display unit includes, for example, a display. As a result, the user can visually recognize the first query information via the terminal display unit. The query information may also be output as audio from an audio output unit provided on the terminal. The audio output unit includes, for example, a speaker.

When the user checks the question information on the terminal, they input a response to the question via the input section of the terminal. As a result, the response to the question is transmitted from the terminal to the server 200. Note that the response to the question may also be transmitted from the terminal to the server 200 via the washing machine 100.

The terminal is an example of an external output device of the present invention. The query information may be received and answered using a terminal instead of the washing machine 100, or using both the washing machine 100 and a terminal. As a result, the user can select a device to receive the query information and answer the query according to their needs.

(3) In the first to third embodiments, as shown in FIGS. 9, 11, and 16, the washing machine storage unit 127 of the washing machine 100 stores operation setting A1 and operation content A2 of the washing machine 100 associated with operation setting A1. However, the present invention is not limited to this. Operation content A2 does not have to be stored in the washing machine storage unit 127. Below, a configuration in which operation content A2 is not stored in the washing machine storage unit 127 will be described with reference to FIGS. 9, 11, and 16.

Operation setting A1 is stored in washing machine memory unit 127, but operation content A2 is not. Registration information 21b of server 200 includes operation setting A1 and operation content A2. When operation setting A1 is selected via selection acceptance unit X (see FIG. 3) of washing machine 100, washing machine control unit 128a communicates with server 200 via washing machine communication unit 126 and obtains operation content A2 from registration information 21b of server 200. As a result, washing machine control unit 128a becomes able to use operation setting A1.

As explained above with reference to Figures 9, 11, and 16, when operation setting A1 is selected via selection receiving unit X, washing machine control unit 128a acquires operation content A2 from server 200. Therefore, washing machine control unit 128a acquires operation content A2 from server 200 as needed. As a result, it is possible to use the memory of washing machine storage unit 127 efficiently.

(4) Before the washing machine 100 performs a wash cycle, it may perform capacity sensing. Capacity sensing refers to a process in which the washing machine control unit 128a calculates the volume of laundry by rotating the drum 115 after laundry has been placed in the drum 115 and no water has been supplied to the drum 115. The volume of laundry that the washing machine 100 can process varies depending on the operation setting.

If the laundry volume calculated by capacity sensing exceeds the capacity that washing machine 100 can process, query information such as the first query information of step S220 (see FIG. 7) asking whether or not to use recommended operation settings may be sent from server 200 to washing machine 100. In this case, the recommended operation settings indicate other operation settings that can process a larger volume of laundry than the operation settings currently being used by washing machine 100. The user then responds to the query from server 200 by pressing wash key 503 (Yes) or dry key 506 (No).

(5) If the reason for sending query information from server 200 to washing machine 100 is that the laundry volume is too large, washing machine 100 may perform the following processing, as described with reference to Figures 2 and 4. In this case, washing machine 100 includes an open/close detection unit that detects whether door 112 is open or closed.

After query information is sent from server 200 to washing machine 100, when the open/close detection unit detects that door 112 has been opened, washing machine control unit 128a determines that the amount of laundry in drum 115 has been reduced. When the open/close detection unit subsequently detects that door 112 has been opened, washing machine control unit 128a performs capacity sensing. Then, washing machine control unit 128a notifies the user via output unit 125 of information indicating that capacity sensing is being performed again.

(6) In the first embodiment, in step S130 (see FIG. 7), the output unit 125 outputs the first query information by voice. In the second embodiment, in step S131 (see FIG. 9), the output unit 125 outputs the second query information by voice. In the third embodiment, in step S132 (see FIG. 12), the output unit 125 outputs the third query information by voice. Hereinafter, the first to third query information may be collectively referred to as query information.

The washing machine 100 may be provided with a playback operation unit that plays back the audio of the question information. This will be described below with reference to Figures 3 and 4. The playback operation unit is, for example, the Listen key 518. As a result, even if the user misses the question information, the user can operate the Listen key 518 to have the audio of the question information played back from the output unit 125 and listen to the question information again. In this case, in response to the question from the server 200, the user can select Yes, No, or Listen Again.

(7) While output unit 125 is outputting the audio query, wash key 503 and dry key 506, which are examples of the response receiving unit of the present invention, may not accept any operation. That is, before the audio query is output, wash key 503 functions as the original key for instructing the laundry wash operation, and dry key 506 functions as the original key for instructing the laundry dry operation. After the audio query is output, wash key 503 functions as a key for selecting Yes, and dry key 506 functions as a key for selecting No. As a result, it is possible to prevent erroneous operation, such as when the user operates wash key 503 to wash laundry when the audio query starts to be output, but washing machine control unit 128a determines Yes. Note that the fact that wash key 503 and dry key 506 do not accept any operation means that washing machine 100 does not operate in response to the operation of wash key 503 and/or dry key 506.

Furthermore, the wash key 503 and dry key 506 may not accept any operation until a predetermined period of time has elapsed from immediately before the output unit 125 starts outputting the audio query information. In other words, the wash key 503 may function as a key for selecting Yes, and the dry key 506 may function as a key for selecting No, before the audio query information output ends. Note that the predetermined period of time from immediately before the audio query information output starts refers to, for example, the period from several hundred milliseconds before the audio query information output starts to two seconds after the audio output starts.

(8) In the first to third embodiments, in step S100 (see Figures 7, 9, and 12), if the reception unit 50 receives input of an operation setting before the output unit 125 starts outputting the audio query information after a trigger operation is performed via the power-on key 514, the process of the output unit 125 outputting the audio query information (see steps S130, S131, and S132) may be canceled.

Also, after a trigger operation is performed via the power-on key 514, if the reception unit 50 receives input of operation settings before the output unit 125 starts outputting the audio query information, but the input of operation settings is interrupted and a predetermined waiting time has elapsed, the output unit 125 may perform processing to output the audio query information. In this case, after the predetermined waiting time has elapsed, the washing machine control unit 128a determines that the user is unsure which operation settings to select. Then, the washing machine control unit 128a controls the output unit 125 to output the audio query information from the output unit 125.

(9) Server 200 may acquire information indicating a first operation log of washing machine 100 from washing machine 100 and determine recommended operation settings based on the information indicating the first operation log. The information indicating the first operation log is information indicating the state of washing machine 100 during operation. The state of washing machine 100 during operation is, for example, the degree of shaking of washing machine 100. In this case, washing machine 100 is equipped with a vibration detection means for detecting the degree of shaking of washing machine 100. The detection results of the vibration detection means are transmitted to server 200 via communication network N (see FIG. 1) and stored in server 200 as a first operation log. Server 200 then determines operation settings for washing machine 100 according to the state of washing machine 100 during operation, such as the degree of shaking of washing machine 100. Server 200 then transmits query information to washing machine 100 indicative of whether or not to use the operation settings determined by server 200. The user then responds to the query from server 200 by pressing wash key 503 (Yes) or dry key 506 (No). As a result, the user can use operation settings that suit the state of the washing machine 100.

(10) Server 200 may acquire information indicating the second operation log of washing machine 100 from washing machine 100, and may determine, based on the information indicating the second operation log, the timing at which washing machine 100 will perform a cleaning operation after washing machine 100 has completed its washing operation. The information indicating the second operation log includes, for example, the degree of dirtiness of washing machine 100 and the history of cleaning operation of washing machine 100. Washing machine 100 is equipped with a sensor that detects a physical quantity indicating the degree of dirtiness of washing machine 100, and transmits the detection value of the sensor to server 200. Washing machine 100 also transmits the history of cleaning operation to server 200. As a result, the degree of dirtiness of washing machine 100 and the history of cleaning operation of washing machine 100 are accumulated in server 200 as the second operation log. Then, server 200 determines, based on the second operation log, the timing at which washing machine 100 will perform a cleaning operation. Then, when the time arrives for washing machine 100 to perform a cleaning operation, after washing machine 100 has finished its wash operation, server 200 sends query information to washing machine 100 informing the user whether or not to perform a cleaning operation. The user then responds to the query from server 200 by pressing wash key 503 (Yes) or dry key 506 (No). As a result, the user can easily recognize when washing machine 100 should be cleaned.

(11) The washing machine 100 in the first to third embodiments is a drum-type washing machine. However, the present invention is not limited to this. The washing machine of the present invention may also be a vertical washing machine.

(12) The recommended operation settings include settings for post-processing operation to be performed after the washing machine 100 completes a washing operation. Post-processing operation refers to, for example, a cleaning operation of the washing machine 100, an operation to prevent laundry wrinkles, or a drying operation to prevent mold and mildew of the washing machine 100. In this case, the server control unit 212 sends query information to the washing machine 100 and/or the terminal, inquiring as to whether or not to use the post-processing operation setting. Then, the output unit 125 of the washing machine 100 and/or the audio output unit of the terminal outputs a voice prompt such as, for example, "Do you want to perform a cleaning operation?" Note that the output unit 125 of the washing machine 100 and/or the audio output unit of the terminal may output a voice prompt after the washing operation completes. As a result, after the washing operation completes, the user hears the voice prompt and can respond to the prompt using the wash key 503 (Yes key) and the dry key 506 (No key).

(13) The washing machine storage unit 127 may store recommendation information 21a. In this case, the output unit 125 outputs query information indicative of a query as to whether or not to use the recommended operation settings stored in the washing machine storage unit 127. In other words, the output unit 125 outputs the query information without going through the server 200. For example, the output unit 125 outputs a query as to whether or not to use a post-processing operation setting such as cleaning operation. The user then responds to the query using the wash key 503 (Yes key) and the dry key 506 (No key). As a result, the user can select operation settings that suit the user's needs for selecting operation settings for the washing machine 100.

The present invention can be used in the field of washing machines and washing machine systems.
