(First Embodiment)
FIG. 1 is a diagram showing a configuration example of the home appliance system 1 of the first embodiment. The home appliance system 1 includes a refrigerator 100, a user terminal device 200, a user information server device 300, and an application server device 400. Further, the refrigerator 100, the user terminal device 200, the user information server device 300, and the application server device 400 are connected to the communication network 900 by communication. The refrigerator 100 includes a refrigerator main body 110, a communication module 120, a sensor group 130, an information device 140, a state value acquisition unit 151, a specific unit 152, a control unit 153, and a storage unit 160.

Even if any one, or two or more of the user terminal device 200, the user information server device 300, the application server device 400, and the communication network 900 has an external configuration of the home appliance system 1. good.
The refrigerator 100 may be composed of two or more devices, such as the specific unit 152 being configured as a device different from the refrigerator 100. For example, as will be described later, the specific unit 152 may be mounted on a learning server device 500 (see FIG. 7) different from the refrigerator 100. The learning server device 500 may be configured as a cloud server.

The home appliance system 1 provides the user with recommended settings according to the user in the refrigerator 100. In particular, the home appliance system 1 identifies recommended settings in the refrigerator 100 and provides them to the user according to the user's operation different from changing the operation settings of the refrigerator 100.
The recommended setting referred to here is an operation setting specified as an operation setting provided to the user by the specific unit 152 among the operation settings of the refrigerator 100. The method in which the home appliance system 1 provides the recommended setting to the user may be a method in which the recommended setting is automatically set in the refrigerator 100. Alternatively, the method in which the home appliance system 1 provides the recommended setting to the user may be a method of presenting information indicating the recommended setting to the user. For example, the user terminal device 200 may display information indicating recommended settings.
Here, it is conceivable to reproduce, for example, the operation settings made in the past according to the operation of the user who changes the operation setting of the refrigerator 100, such as the user operation for the refrigerator 100. However, in this case, it is not possible to provide an operation setting that the user has not made.

Further, it is conceivable to randomly propose, for example, possible operation settings for the refrigerator 100, but there is a high possibility that an operation setting not desired by the user will be proposed, and it is highly likely that it will not benefit the user.
On the other hand, the home appliance system 1 can propose an operation setting that the user has not performed by proposing a recommended setting according to an operation different from changing the operation setting of the refrigerator 100. Moreover, it is expected that the home appliance system 1 can propose an operation setting that meets the user's request or preference by proposing a recommended setting according to the user's operation.

The refrigerator 100 provides the user with a function as a refrigerator in the refrigerator main body 110. Further, the refrigerator 100 provides recommended settings.
The refrigerator body 110 is a part of the refrigerator 100 that performs a function as a refrigerator. For example, each room such as a refrigerator room, a freezer room, a vegetable room, and an ice making room, and a compressor for cooling each room, a heat exchanger, a refrigerant tank, a pipe, etc., perform a cooling function as a refrigerator. Each part for doing so is included in the refrigerator body 110. The refrigerator body 110 operates according to the control of the control unit 153 to provide the user with a function as a refrigerator.

The communication module 120 communicates with other devices. For example, the communication module 120 receives user information including history information of the user's operation from the user information server device 300. This user information is used by the refrigerator 100 to propose recommended settings. Alternatively, the communication module 120 may acquire the user information from another device in addition to or instead of the user information server device 300, such as receiving the history information of the user operation for the user terminal device 200 from the user terminal device 200. You may do it.
Further, the communication module 120 may transmit information on the user's operation regarding the refrigerator 100, such as the opening / closing history of the door of the refrigerator 100, to the user information server device 300 or the user terminal device 200. This information may be displayed on the user terminal device 200 so that the user can confirm the usage status of his / her own refrigerator 100.

The sensor group 130 includes various sensors for detecting the state of the refrigerator 100 or its surroundings. The sensor referred to here is not limited to a specific type. For example, a switch that outputs a binary value, such as a door switch that detects the opening / closing of a door, may be included in the sensor group 130. The sensor group 130 also includes a detection unit that detects a current value of a current flowing through an electric component (for example, a compressor) included in the refrigerator main body 110.

The information device 140 is used as a user interface in the refrigerator 100. For example, the information device 140 may be provided with either or both of a display screen and a speaker to notify the user of various messages related to the refrigerator body 110 such as running out of water in the ice making tank. Further, the information device 140 may provide various information to the user, such as playing a recipe (information on recipe, cooking method, etc.) video.

Further, the display screen of the information device 140 may be configured as a touch panel, or the information device 140 may accept various user operations by holding a microphone and performing voice recognition. For example, the information device 140 may accept a user operation on the refrigerator main body 110 and a user operation on the information device 140 itself.

The state value acquisition unit 151 acquires a state value that quantitatively indicates the state of the refrigerator 100. For example, the state value acquisition unit 151 may acquire the measured value by the sensor group 130 as the state value. The state value acquired by the state value acquisition unit 151 is used, for example, to determine whether or not to switch the mode of the refrigerator 100.

The specifying unit 152 specifies recommended settings (settings suitable for the user) according to the user in the refrigerator 100. As described above for the home appliance system 1, the specifying unit 152 specifies the recommended setting based on the information indicating the user's operation different from changing the operation setting of the refrigerator 100. "User's operation different from changing the operation setting of the refrigerator 100" means the operation of the user who directly changes the operation setting of the refrigerator 100 (for example, the set temperature and the operation mode of the refrigerator 100 after the change are directly specified. It means an operation different from the operation of the user who performs the operation.

The specific unit 152 may directly specify the recommended setting.
As described above for the home appliance system 1, the specific unit 152 may automatically set the specified recommended setting in the refrigerator 100. Alternatively, the specific unit 152 may propose the specified recommended setting to the user by displaying it on the user terminal device 200 or the information device 140, and may not perform the automatic setting.

Alternatively, the specific unit 152 may change the determination condition for setting switching. For example, when the user's operation corresponds to a predetermined operation as an operation when he / she is interested in power saving, the specific unit 152 determines a condition for switching between the normal mode and the power saving mode of the refrigerator 100 (to the power saving mode). The transition condition) may be changed so that the power saving mode can be easily set.

The specific unit 152 may reflect the user's reaction to the recommended setting in the subsequent identification of the recommended setting. For example, when the recommended setting is changed by the user operation such that the user cancels the recommended setting for the recommended setting specified by the specific unit 152, it is considered that the user does not like the recommended setting. In this case, the specific unit 152 may learn how to specify the recommended settings so that the same recommended settings are not specified again or it is difficult to specify the same recommended settings again.

Alternatively, the specific unit 152 may provide the specified recommended setting to the user at a different time zone or a different day of the week from the timing of provision when changed by the user. In this case as well, learn how to specify the recommended settings so that the specific unit 152 will not specify the same recommended settings again after the recommended settings have been changed by the user, or it will be difficult to specify the same recommended settings again. You may try to do it.

The control unit 153 controls each unit of the refrigerator 100. In particular, the control unit 153 controls the refrigerator body 110.
The control unit 153 controls the refrigerator 100 according to the operation setting of the specific unit 152 or the refrigerator 100 specified by the user operation. As a result, the control unit 153 controls the refrigerator 100 based on the operation setting (recommended setting) of the refrigerator 100 specified by the specific unit 152. For example, when the specific unit 152 automatically sets the recommended setting to the refrigerator 100, the control unit 153 controls the refrigerator 100 according to the setting made by the specific unit 152. Even when the specific unit 152 proposes the recommended setting to the user and the recommended setting is set to the refrigerator 100 by the user operation, the control unit 153 controls the refrigerator 100 according to the setting.

For the setting in which the setting switching determination condition is shown, the control unit 153 determines the operation setting according to the determination condition, and controls the refrigerator 100 according to the determined setting. When the specific unit 152 changes the determination condition as described above, the control unit 153 controls the refrigerator 100 according to the changed determination condition.

The storage unit 160 stores various information. The storage unit 160 may store the learning model (learned model) for the specific unit 152 to specify the recommended setting. The specific unit 152 may specify the recommended setting by calculation using this learning model. For example, the specific unit 152 may input the user's motion information or the like into the learning model, and adopt the motion setting output by the learning model as the recommended setting.

The functions of the state value acquisition unit 151, the specific unit 152, and the control unit 153 may be executed by executing a program (software) by one or more hardware processors such as a CPU. Alternatively, all or part of these functional parts may be realized by a circuit part (hardware) such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array). , May be realized by the collaboration of software and hardware. The storage unit 160 may be realized by a RAM (Random Access Memory), a ROM (Read Only Memory), an HDD (Hard Disk Drive), a flash memory, or a combination of a plurality of these.

The user terminal device 200 is a device that accepts user operations. The operation history information of the user terminal device 200 by the user may be used as the information of the user's operation for the specifying unit 152 to specify the recommended setting.
Hereinafter, a case where the user terminal device 200 is a user's smartphone (Smartphone) will be described as an example. For example, the user may install and use an application program that provides information about the refrigerator 100, such as information on the opening / closing history of the door of the refrigerator 100, on the user terminal device 200. Then, the information browsing history information in the user terminal device 200 may be used as information on the user's operation for the specifying unit 152 to specify the recommended setting.

However, the configuration of the user terminal device 200 is not limited to a specific configuration. Various devices that accept user operations can be used as the user terminal device 200. For example, the user terminal device 200 may be configured by using a computer such as a personal computer (PC) or a tablet terminal device (Tablet).

The information of the user's operation for the specifying unit 152 to specify the recommended setting is information indicating the user's operation with respect to the refrigerator 100, information indicating the user's operation (operation) with respect to the information device 140, or the user with respect to the user terminal device 200. Any of the information indicating the operation (operation) of the above, or a combination thereof may be used. However, the information on the user's operation for the specific unit 152 to specify the recommended setting is not limited to these. For example, as information on the user's operation for the specific unit 152 to specify the recommended setting, information indicating an operation in which the user uses a device other than the refrigerator 100, the information device 140, or the user terminal device 200, such as a user's speech to a smart speaker. May be used.

Further, as information on the user's operation for specifying the recommended setting by the specific unit 152, an operation other than the operation performed by the user using the device, such as the user's shopping information (for example, information that the user has made a bulk purchase), is performed. The information shown may be used. The user's shopping information may be obtained, for example, by the refrigerator 100 provided with a camera and taking an image of the user's shopping and acquiring it by image analysis.

The user information server device 300 stores user information. The user information server device 300 may be configured by using, for example, a personal computer or a computer such as a workstation.
As described above, the user information stored in the user information server device 300 may include the history information of the user's operation. The history information of the user's operation may be used as the information of the user's operation for the specific unit 152 to specify the recommended setting. Further, the user information stored in the user information server device 300 may be transmitted to the user terminal device 200 so that the user can browse the user information using the user terminal device 200.
As described above, the user information server device 300 collects information on the user's operation from one or both of the refrigerator 100 and the user terminal device 200, and stores it as (a part of) the user information. You may do it.

The application server device 400 provides an application program used in the user terminal device 200. For example, the application server device 400 may provide an application program for viewing information related to the refrigerator 100, such as information on the opening / closing history of the door of the refrigerator 100. An application program is also simply referred to as an application.
The application server device 400 may be configured by using a computer such as a personal computer or a workstation.

The communication network 900 is not limited to a specific communication network as long as it can provide a communication path between devices. For example, the communication network 900 may be configured to include, but is not limited to, a combination of the Internet and a mobile phone network. The mobile phone network is a wireless communication network provided by a telecommunications carrier for mobile terminal devices such as smartphones.

FIG. 2 is a diagram showing an example of input / output of a learning model stored in the storage unit 160. As described above, the learning model is used by the specific unit 152 to specify the recommended setting.
In the example of FIG. 2, the learning model receives input of user operation information, current time information, and refrigerator operation state information, and outputs recommended setting information.
The recommended setting information is information indicating the recommended setting.

The user operation information is the above-mentioned user operation information. For example, when the user operation information indicates that the user frequently browses the opening / closing history of the door of the refrigerator 100, it is considered that the user is highly interested in the energy consumption (power consumption) of the refrigerator 100. In this case, the specific unit 152 may use the learning model to specify the power saving mode setting or the mode determination condition setting that tends to be the power saving mode as a recommended setting.

The current time information is information indicating the current date and time. For example, it is conceivable that the usage status of the refrigerator 100 or the state of the refrigerator 100 differs depending on time factors such as a time zone, a day of the week, and a season, such as the frequency of opening and closing the door of the refrigerator 100 differs between day and night. Therefore, the specifying unit 152 may specify the recommended setting according to the current date and time by using the learning model.

The refrigerator operating state information is information indicating the state of the refrigerator 100. The refrigerator operation state information includes, for example, the operation mode (operation status) of the refrigerator 100, the air temperature in the refrigerator, the temperature of the cooler, and the like. For example, it is conceivable that the appropriate operation setting differs depending on the state of the refrigerator 100 such as the amount of food stored in the refrigerator compartment. Therefore, the specifying unit 152 may specify the recommended setting according to the state of the refrigerator 100 by using the learning model.

However, the information input to the learning model is not limited to a specific one as long as it includes information on the user's behavior. For example, one or both of the current time information and the refrigerator operating state information may not be input to the learning model. Alternatively, the learning model may receive input other than the information shown in FIG. 2, such as receiving input of setting status information in another refrigerator in addition to or instead of the current time information and refrigerator operating state information. May be good.

The learning of the learning model is a teacher who indicates the operation setting that the person in charge of learning (for example, the engineer of the manufacturer of the refrigerator 100) considers appropriate for the input data such as the user operation information, the current time information, and the refrigerator operation state information. It may be performed using the learning data to which the data is associated. The trained learning model may be implemented in the refrigerator 100. The refrigerator 100 does not have to have a learning function for updating the learning model.

Alternatively, the specific unit 152 may update the learning model according to the user's reaction to the recommended setting. As described above, when the recommended setting is changed by the user operation such as the user canceling the recommended setting, the specific unit 152 does not specify the same recommended setting again, or it is difficult to specify the same recommended setting again. The learning model may be updated so that it becomes. For example, the specific unit 152 uses the learning data in which the data indicating the operation setting after the user changes is linked as the teacher data to the data input to the learning model by the specific unit 152 itself to specify the recommended setting. You may want to make this change in the machine learning you were using.

The structure of the learning model is not limited to a specific one. For example, even if the training model is configured using a neural network (NN), a support vector machine (SVM), a random forest (Random Forest), a regression model, or a combination thereof. good. Further, the learning model is not limited to the software-like model stored in the storage unit 160, and may be configured by using hardware.
Further, the specifying unit 152 specifies the recommended setting by using a specific method determined by a method other than machine learning, such as specifying the recommended setting by using the inference rule defined by the designer of the refrigerator 100. May be good.

FIG. 3 is a diagram showing an example of a function that the user terminal device 200 can execute in an application program. The specific unit 152 may input the execution history of these functions into the learning model as user operation information.
The remote control function is a function of performing operations on the refrigerator 100 such as operation settings of the refrigerator 100 from the user terminal device 200 via a server device for remote control. In the example of FIG. 3, the user changes the set temperature of the refrigerating room, changes the set temperature of the freezing room, switches the chilled mode of the chilled room (such as changing to the quenching mode or the chilled mode of a special mode), and the ice making room. Ice making mode switching (rapid change to ice making mode, etc.), freezing mode switching in the freezer room, and automatic power saving mode switching can be performed remotely.

If the user frequently uses the remote control function, it is considered that he / she is highly interested in the operation setting of the refrigerator 100. In this case, the specific unit 152 may specify the recommended setting more frequently.
The specific unit 152 may specify the recommended setting based on the usage history of the remote control function. For example, when the specifying unit 152 makes it easy to select an operation setting that is frequently used as a recommended setting, it is expected that it becomes easy to specify an operation setting that suits the user's request or preference. Alternatively, when the specific unit 152 makes it easy to select an operation setting that is not frequently used as a recommended setting, it is expected that an operation setting that the user has never used or an operation setting that the user is not familiar with can be proposed to the user as a recommended setting. Will be done.

The specific unit 152 can make a quantitative determination such as whether or not the user frequently uses the remote control function by using the threshold value. For example, as a determination of whether or not the specific unit 152 corresponds to the above-mentioned "when the user frequently uses the remote control function", whether or not the frequency of the user using the remote control function is higher than a predetermined threshold value. It may be determined whether or not.
The same applies to the quantitative determination other than "when the user frequently uses the remote control function".

The door opening / closing history function is a function for the user to check the opening / closing history of the door of the refrigerator 100. In the example of FIG. 3, the user can select either the daily history or the weekly history and display it on the user terminal device 200.
As described above, when the user frequently checks the door opening / closing history, it is considered that the user is highly interested in the power consumption of the refrigerator 100. In this case, the specifying unit 152 may specify, as a recommended setting, the setting of the power saving mode or the setting of the mode determination condition that tends to be the power saving mode. As described above, the specific unit 152 consumes the refrigerator 100 according to the user based on the information indicating the confirmation operation of the user who confirms the opening / closing history of the door of the refrigerator 100 (for example, the information indicating the number of confirmation operations of the user). The power setting may be specified as a recommended setting.

When the specifying unit 152 specifies the setting of the mode determination condition such that the refrigerator 100 is likely to be in the power saving mode, the specifying unit 152 specifies one or both of the temperature threshold value and the time threshold value related to the temperature inside the refrigerator 100. May be good. For example, the condition for switching from the power saving mode other than the power saving mode (for example, the normal mode) to the power saving mode is that the temperature inside the refrigerator is within a predetermined range (for example, a stable state within a predetermined range) for a predetermined time or longer. May be. In this case, the specifying unit 152 specifies the temperature threshold so that the lower temperature threshold indicating the range of the temperature inside the refrigerator is lowered, the upper temperature threshold is raised, or both are performed. May be good. Further, the specifying unit 152 may specify the time threshold value so that the predetermined time is shortened.
In the power saving mode, the control unit 153 reduces the operating frequency of the compressor of the refrigerator 100, reduces the rotation speed of the fan, extends the time interval of the defrosting process in the refrigerator 100, and reduces the illumination of the lighting in the refrigerator 100. Any one or a combination thereof may be used.

The Mimamori function is a function of notifying the user terminal device 200 when a preselected condition is satisfied. In the example of FIG. 3, the user receives the notification as a condition that the door is not opened / closed in the designated time zone, the door is opened / closed in the designated time zone, or the temperature near the refrigerator is high. You can select one or more of.

For example, if the condition of notifying when the door is opened / closed during the specified time is frequently selected, it is assumed that the door will not be opened / closed during that time due to the user going out or going to bed. It is conceivable that you will be notified when the door is opened or closed unexpectedly. By not opening and closing the door, the temperature inside the refrigerator may be maintained and power saving may be possible. Therefore, even if the specific unit 152 specifies, as a recommended setting, the setting of the power saving mode or the setting of the mode determination condition that tends to be the power saving mode for the time zone in which this condition is frequently specified. good.

The foodstuff management function is a function for the user to confirm the type, amount, expiration date, etc. of the foodstuff stored in the refrigerator 100. For example, the user terminal device 200 may display information such as the type, amount, and expiration date of the food material in a list for each storage room such as a freezing room and a refrigerating room. The expiration date referred to here may be the expiration date. Information on ingredients used for the ingredient management function is also referred to as ingredient management information.

The specific unit 152 may specify the recommended setting based on the expiration date shown in the food material management information. For example, when there are many foodstuffs whose expiration date is near, the specific unit 152 automatically lowers the temperature control in the refrigerator, puts it in a rapid cooling mode, uses the sterilization function, or uses the deodorization function. , Or a combination of these may be specified as a recommended setting. This is expected to keep the freshness of the ingredients for a relatively long time.
Further, when the number of foodstuffs having a near expiration date is high, the specific unit 152 may specify as a recommended setting that the temperature in the refrigerator is constantly set lower than the standard temperature.

The specific unit 152 may specify the recommended setting based on the input status of the expiration date information. For example, when the user inputs the expiration date of all the ingredients registered in the ingredient management function many times, the user may be concerned about the freshness of the ingredient. In this case, the specifying unit 152 may specify as a recommended setting a setting for keeping the freshness of the food material longer, such as setting the temperature inside the refrigerator to be lower than the standard temperature.

The specifying unit 152 may specify the recommended setting based on the information indicating the tendency of the operation regarding the user's purchase. For example, if users tend to buy in bulk, it may take time to use up the purchased ingredients. In this case, the specific unit 152 sets the temperature inside the refrigerator lower than the standard temperature, or quickly cools the foodstuffs purchased in bulk with the rapid cooling function, so that the freshness of the foodstuffs can be maintained for a longer time. , You may specify it as a recommended setting.

As described above, the tendency of the operation regarding the user's purchase may be acquired by, for example, the refrigerator 100 provided with a camera to take an image of the user's shopping and perform image analysis. Alternatively, the specifying unit 152 may grasp the tendency of the user's purchasing operation from the foodstuff management information registered by the user in the foodstuff management function.

Further, the specific unit 152 may specify the recommended setting based on the nutritional component specified from the type of the food material. For example, if some of the foodstuffs stored in the refrigerator 100 can increase the nutritional content when the temperature is high, the specific unit 152 specifies a setting that raises the temperature inside the refrigerator for a predetermined time as a recommended setting. You may do so.
In addition, here, the food material is also referred to as food. That is, the phrase "foodstuff" and the phrase "food" are not distinguished, and are used as a phrase that refers to food in general.

The specifying unit 152 may specify the recommended setting based on the information of the operation related to the confirmation of the nutrition information of the user. For example, if a user is performing an operation to check the nutrition of foodstuffs, such as accessing a site that provides information on the nutritional components of foodstuffs on the Internet, it is considered that the interest in cormorants is high. In this case, the setting in which the specifying unit 152 raises the temperature in the refrigerator for a predetermined time in order to increase the nutritional components of the foodstuff may be specified as the recommended setting.

Further, the specifying unit 152 may specify the recommended setting based on the number of times the user confirms the food management information for each storage room (storage unit) and / or the number of times the door of the storage room is opened / closed. good. For example, if the user checks the food management information for a specific storage room (refrigerating room, freezing room, or vegetable room) more than a predetermined ratio than other storage rooms, the user enters the storage room. It is considered to be of high interest. In this case, the specifying unit 152 may make it easier to specify the operation setting related to this storage room as a recommended setting. Alternatively, the specific unit 152 may specify a setting for preferentially cooling the storage chamber as a recommended setting.

The recipe function is a function for the user to refer to the recipe. For example, the user terminal device 200 may display a recipe search screen or a recipe list, and display a recipe specified by the user.
The specifying unit 152 may specify the recommended setting based on the action of the user referring to the recipe. For example, when the user actually cooks by referring to the recipe, it is conceivable to open the door of the refrigerator 100 and take out the ingredients. Therefore, the specifying unit 152 may specify the recommended setting so as to lower the temperature in the refrigerator at the timing when the user refers to the recipe.

The power consumption display function is a function for the user to confirm the power consumption of the refrigerator 100. In the power consumption display function, the user terminal device 200 may display the history of the power consumption of the refrigerator 100 or the average value of the power consumption of the refrigerator 100 during the immediate neighborhood period.

In this way, the specific unit 152 consumes the refrigerator 100 according to the user based on the information indicating the confirmation operation of the user who confirms the power consumption of the refrigerator 100 (for example, the number of confirmation operations of the user who confirms the power consumption). The operation setting related to power may be specified as a recommended setting.

FIG. 4 is a diagram showing an example of items of input data to the learning model. In the example of FIG. 4, the item of the application operation history and the item of the refrigerator operating state are shown.
Each item of the application operation history corresponds to an example of the item of the user operation information input to the learning model. For each application program such as remote operation and door opening / closing history exemplified in FIG. 3, the specific unit 152 provides user operation information on the screen display count, screen display time, operation time, and function selection count in the application program. It may be input to the learning model as. In addition, the specific unit 152 may input the history information for each item of each function (each application program) shown in FIG. 3 and the history information for each setting into the learning model as user operation information. ..

Each item of the refrigerator operation state corresponds to an example of the item of the refrigerator operation state information input to the learning model. The state of the refrigerator 100 is shown by the sensing data by the sensors such as the refrigerating room door switch and the vegetable room door switch exemplified in FIG. By inputting the data of these items into the learning model as the refrigerator operating state information, the specifying unit 152 is expected to specify an effective operation setting as a recommended setting according to the state of the refrigerator 100.

The specific unit 152 may perform image display and / or audio output on the information device 140, or any one of them, in response to a user operation in which the user seems to be in front of the refrigerator 100. For example, the specific unit 152 may execute an application program to display an image and output audio in the information device 140, or to output either one of them. The execution of the application program in this case may correspond to an example of implementing the recommended setting, or may be different from the recommended setting such as playback of an entertainment video.

Examples of user actions in which the user seems to be in front of the refrigerator 100 include actions for taking out ingredients from the refrigerator 100, actions for referring to a recipe presented by the information device 140, and actions for opening and closing the door of the refrigerator 100. Not limited to.
As a result, it is expected that the specific unit 152 can reach out to the user at an appropriate timing when the user is in front of the refrigerator 100.

The specific unit 152 stores the timing when the user puts the food in the refrigerator 100, and lowers the temperature inside the refrigerator at the same timing, for example, at the same time on the same day of the week (for example, lowers the temperature inside the refrigerator first). The recommended setting may be specified so that the defrosting operation is performed first so that the cooling can be performed at that timing.
As a result, when the user puts the ingredients in the refrigerator 100 at the same timing, such as when the user goes shopping at the same time on the same day of the week, the newly stored ingredients can be quickly cooled, and the freshness of the ingredients can be obtained. Is expected to be able to keep.
The specific unit 152 may detect the timing when the user puts the food in the refrigerator 100 by referring to the information registered in the food management application (the application program that provides the function for managing the food). .. Alternatively, the specific unit 152 may detect the timing when the user puts the food in the refrigerator 100 by performing the image recognition process on the image of the camera in the refrigerator.

The specifying unit 152 may specify as a recommended setting a setting for lowering the temperature inside the refrigerator, such as a rapid cooling mode, for an operation in which the user puts a relatively high temperature food material into the refrigerator 100.
As a result, it is expected that the newly stored foodstuff can be cooled quickly and the freshness of the foodstuff can be maintained. In addition, it is expected that the temperature inside the refrigerator will be kept relatively low and the freshness of ingredients other than the newly stored ingredients can be maintained.

An application program related to shopping, such as a connection to a mail-order site or payment of electronic money, as an example of a method in which the specific unit 152 detects an operation in which a user puts a relatively hot food material into the refrigerator 100. ), Detection of opening and closing of the door of the refrigerator 100, detection of an increase in the temperature inside the refrigerator, and detection of events associated with the user's shopping. Further, as an example of the method of detecting the operation of the user to put the food having a relatively high temperature into the refrigerator 100, the specific unit 152 detects the operation of the user referring to the recipe, detects the opening / closing of the door of the refrigerator 100, and the inside of the refrigerator. It is possible to detect an event associated with the user cooking, such as detection of an increase in temperature. However, the method by which the specific unit 152 detects the operation of the user putting the food material having a relatively high temperature into the refrigerator 100 is not limited to these methods.

The specifying unit 152 may specify the operation setting related to ice making according to the user as a recommended setting based on the information indicating the user's action for the notification of the water shortage of the ice making tank.
For example, if the user does not confirm the notification that the ice tank is out of water, or if the user confirms the notification but does not replenish the water, it is possible that the user has not requested ice making. In this case, the specifying unit 152 may specify a setting that does not perform automatic ice making as a recommended setting.
Alternatively, if the user refills water (within a predetermined time) immediately after being notified that the ice tank is out of water, it is possible that the user wants more ice. In this case, the specifying unit 152 may specify a setting for increasing the ice making speed as a recommended setting.

FIG. 5 is a diagram showing an example of a processing procedure in which the refrigerator 100 provides a recommended setting to the user. The refrigerator 100 repeats the process of FIG. 5 at regular intervals, for example.
In the process of FIG. 5, the specific unit 152 acquires the input data to the learning model (step S111). For example, the specifying unit 152 acquires the user operation information, the current time information, and the refrigerator operating state information exemplified in FIG. 2 as input data to the easy-hand model.

Next, the specifying unit 152 specifies the recommended setting (step S112). Specifically, the specifying unit 152 inputs the data obtained in step S111 into the learning model, and specifies the operation setting output by the learning model as a recommended setting.
Next, the specific unit 152 determines whether or not the recommended setting is valid (step S113). For example, if the operation setting specified in step S112 is already the current operation setting of the refrigerator 100, the specifying unit 152 determines that the specified recommended setting is invalid. Alternatively, the learning model may not output the recommended settings. If the learning model does not output the recommended settings, the specific unit 152 determines that the recommended settings are invalid.

When the specific unit 152 determines that the recommended setting is invalid (step S113: NO), the refrigerator 100 ends the process of FIG.
On the other hand, when it is determined that the recommended setting is valid (step S113: YES), the specific unit 152 automatically sets the specified recommended setting in the refrigerator 100 (step S114). Alternatively, the specific unit 152 may not perform automatic setting, but may propose to the user by displaying the specified recommended setting on the user terminal device 200. The user may select in advance whether or not the specific unit 152 automatically sets the recommended setting in the refrigerator 100.

Next, the specific unit 152 reports to the user that the recommended setting is automatically set in the refrigerator 100 (step S115). For example, the specific unit 152 reports by transmitting a message to the effect that the recommended setting is automatically set in the refrigerator 100 to the user terminal device 200 via the communication module 120 and displaying the message.
After step S115, the refrigerator 100 ends the process of FIG.

FIG. 6 is a diagram showing an example of a processing procedure in which the refrigerator 100 reflects the user reaction to the recommended setting in the learning result. The refrigerator 100 performs the process of FIG. 6 after a predetermined time has elapsed, for example, one hour after the recommended setting is automatically set in the refrigerator 100 in step S114 of FIG.
In the process of FIG. 6, the specific unit 152 acquires refrigerator operation information (step S121). The refrigerator operation information here includes information indicating the current operation setting of the refrigerator 100.
Next, the specific unit 152 determines whether or not the setting has been changed from the recommended setting (step S122). For example, the specific unit 152 determines whether the current operation setting of the refrigerator 100 indicated by the refrigerator operation information is different from or the same as the recommended setting.

When the specific unit 152 determines that the setting has not been changed from the recommended setting (step S122: NO), the refrigerator 100 ends the process of FIG.
On the other hand, when it is determined that the setting has been changed from the recommended setting (step S122: YES), the specific unit 152 feeds back the result that the recommended setting has not been adopted to the learning model (step S123). As described above, the learning model is updated so that the specific unit 152 does not specify the same recommended setting again, or it becomes difficult to specify the same recommended setting again. As described above, the specific unit 152 may make this change by machine learning.
After step S123, the refrigerator 100 ends the process of FIG.

As described above, the specifying unit 152 specifies the operation setting of the home electric appliance according to the user based on the information indicating the operation of the user different from changing the operation setting of the home electric appliance (for example, the refrigerator main body 110). .. The control unit 153 notifies the user of a proposal to control the home electric appliance or change the operation setting of the home electric appliance based on the operation setting of the home electric appliance specified by the specific unit 152.
As a result, the home appliance system 1 can support the use of user-configurable functions.
Here, it is conceivable to reproduce, for example, the operation settings made in the past according to the operation of the user who changes the operation settings of the home electric appliance such as the user operation for the home electric appliance, but in this case, the user does not perform the operation setting. It is not possible to propose operation settings.

Further, it is conceivable to randomly propose, for example, possible operation settings for home appliances, but there is a high possibility that operation settings not desired by the user will be proposed, and it is highly likely that it will not benefit the user.
On the other hand, the home appliance system 1 can propose an operation setting that is not performed by the user by proposing a recommended setting according to an operation different from changing the operation setting of the home appliance. Moreover, the home appliance system 1 is expected to be able to propose an operation setting that suits the user's request or preference even if the user does not know the existence of the mode or the content of the mode by proposing the recommended setting according to the user's operation. Will be done. This makes it possible to improve convenience.

In addition, the state value acquisition unit 151 acquires a state value that quantitatively indicates the state of the home electric appliance. The specifying unit 152 specifies a threshold value for controlling a home electric appliance according to the user based on the information indicating the operation of the user. The control unit 153 controls the home electric appliance based on the state value acquired by the state value acquisition unit 151 and the threshold value specified by the specific unit 152.
In this way, instead of directly specifying the operation setting by the specifying unit 152, by specifying the threshold value, the control unit 153 responds to the state value acquired by the state value acquiring unit 151 such as the temperature inside the refrigerator. Home appliances can be controlled by the operation settings. According to the home appliance system 1, in this respect, it is expected that the home appliances can be appropriately controlled according to the state of the home appliances.
Further, the specifying unit 152 may specify (change) a threshold value already provided for controlling the home electric appliance. In this respect, changes to the existing control logic for reflecting the identification by the specific unit 152 in the control of the home electric appliance can be small.

Further, when the setting is changed by the user's operation from the operation setting specified by the specific unit 152, the specific unit 152 suppresses the specification of the operation setting before the change again.
When the user changes the setting from the operation setting specified by the specific unit 152, it is considered that the user does not want the operation setting specified by the specific unit 152. It is expected that the specifying unit 152 can specify the operation setting that suits the user's request or preference by suppressing the specification of the operation setting in this case again.

The specific unit 152 consumes the refrigerator 100 according to the user based on the information indicating the confirmation operation of the user who confirms the opening / closing history of the door of the refrigerator 100 (for example, the number of confirmation operations of the user who confirms the opening / closing history of the door). Identify operating settings related to power.
When the number of confirmation operations of the user who confirms the opening / closing history of the door of the refrigerator 100 is large, it is considered that the user is highly interested in the power consumption of the refrigerator 100. In this case, it is expected that the specifying unit 152 can specify the operation setting that meets the user's request or preference, for example, by specifying the operation setting that reduces the power consumption of the refrigerator 100.

Further, the specifying unit 152 specifies at least one of a temperature threshold value and a time threshold value related to the temperature inside the refrigerator 100 as an operation setting related to the power consumption of the refrigerator. The control unit 153 controls the refrigerator 100 based on at least one of the temperature threshold value or the time threshold value specified by the specific unit 152.
In this way, instead of directly specifying the operation setting of the refrigerator 100 by the specifying unit 152, by specifying the temperature threshold value or the time threshold value, the control unit 153 can set the stable time of the refrigerator temperature or the refrigerator temperature, for example. The refrigerator 100 can be controlled by the operation setting based on the above. In this respect, the control unit 153 can control the refrigerator 100 by setting the operation according to the state of the refrigerator 100. According to the home appliance system 1, in this respect, it is expected that the refrigerator 100 can be appropriately controlled according to the state of the refrigerator 100.
Further, the specifying unit 152 may specify a threshold value already provided for controlling the refrigerator 100. In this respect, changes to the existing control logic for reflecting the identification by the specifying unit 152 in the control of the refrigerator 100 can be made small.

Further, the specifying unit 152 relates to the power consumption of the refrigerator 100 according to the user based on the information indicating the confirmation operation of the user who confirms the power consumption of the refrigerator 100 (for example, the number of confirmation operations of the user who confirms the power consumption). Identify the behavior settings. When the number of confirmation operations of the user who confirms the power consumption of the refrigerator 100 is large, it is considered that the user is highly interested in the power consumption of the refrigerator 100. In this case, it is expected that the specifying unit 152 can specify the operation setting that meets the user's request or preference, for example, by specifying the operation setting that reduces the power consumption of the refrigerator 100.

Further, the specifying unit 152 specifies an operation setting related to temperature control of the refrigerator 100 according to the user, based on the operation of the user who inputs the expiration date of the food stored in the refrigerator.
For example, when the user inputs the expiration date of all the ingredients registered in the ingredient management function many times, the user may be concerned about the freshness of the ingredient. In this case, the specific unit 152 sets the temperature inside the refrigerator to be lower than the standard temperature, and by specifying the settings for keeping the freshness of the ingredients for a longer time, the operation settings that meet the user's request or preference can be set. Expected to be identifiable.

Further, the specifying unit 152 specifies the operation setting regarding the temperature control of the refrigerator 100 according to the user, based on the information indicating the tendency of the operation regarding the purchase of the user.
For example, if users tend to buy in bulk, it may take time to use up the purchased ingredients. In this case, the specific unit 152 sets the temperature inside the refrigerator lower than the standard temperature, or quickly cools the foodstuffs purchased in bulk with the rapid cooling function, so that the freshness of the foodstuffs can be maintained for a longer time. By doing so, it is expected that the operation setting that suits the user's request or preference can be specified.

Further, the specifying unit 152 specifies the operation setting related to the temperature control of the refrigerator according to the user based on the information indicating the user's confirmation operation regarding the nutrition of the food (for example, the number of times the user confirms the nutrition of the food). ..
In this case, it is considered that the user is highly interested in the nutrition of the food. It is expected that the specifying unit 152 can specify the operation setting that meets the user's request or preference by specifying the operation setting related to the temperature control of the refrigerator.
For example, if some of the foodstuffs stored in the refrigerator 100 can increase the nutritional content when the temperature is high, the specific unit 152 specifies a setting that raises the temperature inside the refrigerator for a predetermined time as a recommended setting. You may do so.

Further, the specific unit 152 is the temperature of the refrigerator 100 according to the user based on the information indicating the user's operation regarding the specific storage unit included in the refrigerator 100 (for example, the number of times the user opens and closes the specific storage unit). Identify management behavior settings.
When the number of confirmation operations of the user for a specific storage unit is large, it is considered that the user is highly interested in the storage unit (uses the storage unit frequently). By specifying the operation setting based on the information indicating the number of confirmation operations of the user regarding the specific storage unit, the specific unit 152 is of interest to the user, for example, specifying the setting for preferentially cooling the storage unit. It is expected that the operation settings can be appropriately specified according to the above.

Further, the specifying unit 152 specifies the operation setting related to the temperature control of the refrigerator 100 in a specific time zone according to the user, based on the information indicating the operation of the user who puts the food in the refrigerator at the specific time zone.
As a result, it is expected that the home appliance system 1 can appropriately control the temperature of the refrigerator 100 according to the timing when the user puts the food in the refrigerator 100, and can maintain the freshness of the food.

For example, the specifying unit 152 stores the timing when the user puts the food in the refrigerator 100, and specifies the recommended setting so that the temperature inside the refrigerator is lowered at the same timing such as the same time on the same day of the week. You may.
As a result, when the user puts the ingredients in the refrigerator 100 at the same timing, such as when the user goes shopping at the same time on the same day of the week, the newly stored ingredients can be quickly cooled, and the freshness of the ingredients can be obtained. Is expected to be able to keep.

Further, the specifying unit 152 specifies the operation setting related to ice making according to the user, based on the information indicating the user's action for the notification of the water shortage of the ice making tank.
Thereby, it is expected that the specifying unit 152 can specify the operation setting that meets the user's request or preference regarding ice making.
For example, if the user does not confirm the notification that the ice tank is out of water, or if the user confirms the notification but does not replenish the water, it is possible that the user has not requested ice making. In this case, the specifying unit 152 may specify a setting that does not perform automatic ice making as a recommended setting.
Alternatively, if the user refills water (within a predetermined period of time) immediately after being notified that the ice tank is out of water, it is possible that the user wants more ice. In this case, the specifying unit 152 may specify a setting for increasing the ice making speed as a recommended setting.
