The compressor supplies refrigerant to the first cooler and the second cooler. The first blower supplies cold air cooled by the first cooler to the storage room 30 in the refrigeration temperature range. The second blower supplies cold air cooled by the second cooler to the storage room 30 in the freezing temperature range.

<2.4 Communication Department>
The communication unit 140 is, for example, a wireless communication module. The communication unit 140 is capable of communicating with the server 200 via a wireless router WR and a modem M placed in the user U's residence.

<2.5 Control section>
Control unit 150 is realized by one or more hardware processors such as a CPU (Central Processing Unit) installed in refrigerator 100 executing a program. However, part or all of the control unit 150 may be realized by hardware such as an ASIC (Application Specific Integrated Circuit), a PLD (Programmable Logic Device), or an FPGA (Field Programmable Gate Array), or may be realized by a combination of software and hardware. It may also be realized by cooperation with software.

Control unit 150 centrally controls refrigerator 100 as a whole. For example, the control unit 150 controls the cooling unit 130 based on the set temperature (target temperature) of each storage compartment 30 and the detection result of the temperature sensor 120, so that the cooling unit 130 cools each storage compartment 30. For example, the control unit 150 controls the compressor contained in the cooling unit 130 by PID (Proportional-Integral-Differential) control based on the difference between the set temperature (target temperature) of each storage chamber 30 and the temperature detected by the temperature sensor 120. the first blower, and the second blower.

The control unit 150 causes the storage unit 180 to store the detection result of the door opening/closing detection sensor 110 as door opening/closing information 181. The door opening/closing information 181 includes information regarding door opening/closing every predetermined unit time (for example, one hour). For example, the door opening/closing information 181 indicates the number of times the door is opened/closing per predetermined unit time or the door opening time. "Door open time" is the total time the door remains open. The control unit 150 causes the storage unit 180 to hold the door opening/closing information 181 for at least a predetermined period of time (for example, three hours). The predetermined time period is twice or more the predetermined unit time period.

Based on the detection result of the temperature sensor 120 and a preset threshold, the control unit 150 determines whether or not a large temperature increase exceeding the threshold (for example, a temperature increase exceeding 10° C. as a temperature difference) has occurred in each storage chamber 30. is determined at a predetermined period. The “large temperature increase” is, for example, a temperature increase that occurs when warm stored items are stored in the storage chamber 30. When determining that a large temperature rise has occurred in a certain storage room 30, the control unit 150 causes the storage unit 180 to store information that a large temperature rise has occurred in the storage room 30 as temperature rise information 182. The temperature rise information 182 includes whether there is a large temperature rise in each storage chamber 30 every predetermined unit time (for example, one hour). The control unit 150 causes the storage unit 180 to hold the temperature rise information 182 for the predetermined period (for example, 3 hours).

The control unit 150 includes a timer 151. Control unit 150 transmits usage state information indicating the usage state of refrigerator 100 to server 200 every predetermined unit time (for example, one hour) measured by timer 151. The usage status information includes information detected in the refrigerator 100. In this embodiment, the usage state information includes door opening/closing information 181 and temperature rise information 182 stored in the storage unit 180.

In this embodiment, the usage state information includes information detected in the refrigerator 100 most recently and in the past. For example, the usage state information includes latest information, first past information, and second past information. The most recent information includes door opening/closing information 181 and temperature rise information 182 regarding the most recent predetermined unit time (for example, the most recent one hour from the time of transmission) in the refrigerator 100. The first past information includes door opening/closing information 181 and temperature rise information 182 regarding the previous predetermined unit time (for example, the time between two hours and one hour before the transmission time). The second past information includes door opening/closing information 181 and temperature rise information 182 regarding the predetermined unit time two hours ago (for example, the time between 3 hours and 2 hours before the transmission time).

Further, in this embodiment, the control unit 150 acquires a control command for the refrigerator 100 generated by the server 200 from the server 200 via the communication unit 140. An example of the control command for the refrigerator 100 is a special operation execution command for reducing the power consumption of the refrigerator 100. The special operation will be described in detail later. Control unit 150 controls cooling unit 130 based on control commands obtained from server 200. For example, when acquiring a special operation execution command as the control command, the control unit 150 performs the special operation of the refrigerator 100 based on the execution command.

The control unit 150 causes the storage unit 180 to store the execution result of the special operation as execution result information 183. The execution result information 183 includes, for example, whether or not a special operation is performed every predetermined unit time (for example, one hour). The execution result information 183 is, for example, information indicating which of a normal operation, a first special operation, or a second special operation, which will be described later, was executed every predetermined unit time (for example, one hour). The control unit 150 causes the storage unit 180 to hold the execution result information 183 for the predetermined period of time (for example, three hours).

The control unit 150 transmits the execution result information 183 to the server 200 at predetermined unit times (for example, every hour) measured by the timer 151. Execution result information 183 includes execution results of special operations executed recently and in the past in refrigerator 100. For example, the execution result information 183 includes latest information, first past information, and second past information. The most recent information includes execution results of special operation in the refrigerator 100 regarding the most recent predetermined unit time (for example, the most recent 1 hour from the time of transmission). The first past information includes the execution result of the special operation regarding the previous predetermined unit time (for example, the time from 2 hours to 1 hour before the transmission time). The second past information includes the execution result of the special operation regarding the predetermined unit time two hours ago (for example, the time between 3 hours and 2 hours before the transmission time).

<2.6 Storage section>
The storage unit 180 is a functional unit that stores various information. The storage unit 180 is realized by a combination of RAM (Random Access Memory), ROM (Read Only Memory), EEPROM (Electrically Erasable Programmable ROM), SSD (Solid State Drive), or the like. The storage unit 180 stores door opening/closing information 181, temperature rise information 182, and execution result information 183.

<3. Server＞
Next, the server 200 will be explained in detail.
FIG. 4 is a block diagram showing the functional configuration of the server 200. The server 200 includes, for example, an information acquisition section 210, an operation plan generation section 220, a control command output section 230, an implementation rate calculation section 240, an information output section 250, and a storage section 280.

The information acquisition section 210, the operation plan generation section 220, the control command output section 230, the implementation rate calculation section 240, and the information output section 250 are configured such that one or more hardware processors such as a CPU installed in the server 200 execute programs. This is achieved by executing. However, some or all of these functional units may be realized by hardware such as ASIC, PLD, or FPGA, or may be realized by cooperation between software and hardware. Note that these functional units may be provided separately in a plurality of server devices. Further, one or more of these functional units may be provided in the terminal device 300 or the refrigerator 100 instead of the server 200.

<3.1 Information acquisition section>
Information acquisition section 210 acquires usage status information transmitted from refrigerator 100. The information acquisition unit 210 stores the usage status information acquired from the refrigerator 100 in the storage unit 280 as part of the usage status accumulation information 281. In the present embodiment, when the usage state information is acquired from the refrigerator 100, the information acquisition unit 210 acquires first past information and second past information included in the newly acquired usage state information based on the usage state accumulation information 281. It is determined whether the information has already been acquired and stored.

Then, when the first past information and the second past information included in the newly acquired usage state information are information that has already been acquired and stored, the information acquisition unit 210 acquires information about the first past information and the second past information. is discarded, and the most recent information is stored as part of the usage state storage information 281. On the other hand, if at least one of the first past information and the second past information included in the newly acquired usage state information is unaccumulated information (for example, if it could not be acquired due to communication interruption in the past), the unaccumulated The information is stored as part of usage state storage information 281. Thereby, the information acquisition unit 210 accumulates usage state information of the refrigerator 100 from the past to the most recent.

Information acquisition section 210 acquires execution result information 183 transmitted from refrigerator 100. The information acquisition unit 210 causes the storage unit 280 to store the execution result information 183 acquired from the refrigerator 100 as part of the execution result accumulation information 282. In this embodiment, when the execution result information 183 is acquired from the refrigerator 100, the information acquisition unit 210 acquires the first past information and the second past information included in the newly acquired execution result information 183 based on the execution result accumulation information 282. It is determined whether the past information has already been acquired and stored.

Then, if the first past information and the second past information included in the newly acquired execution result information 183 have already been acquired and stored, the information acquisition unit 210 acquires the first past information and the second past information. is discarded, and the latest information is newly stored as part of the execution result storage information 282. On the other hand, if at least one of the first past information and the second past information included in the newly acquired execution result information 183 is unaccumulated information (for example, when it could not be acquired due to communication interruption in the past), the unaccumulated information is newly accumulated as part of the execution result accumulation information 282. Thereby, the information acquisition unit 210 accumulates the execution result information 183 of the refrigerator 100 from the past to the latest.

<3.2 Operation plan generation section>
The driving plan generation unit 220 analyzes the lifestyle pattern of the user U (the usage pattern of the refrigerator 100) based on the usage status information for a predetermined period (for example, the past two weeks) included in the usage status accumulation information 281, and generates a lifestyle pattern of the user U. An operation plan for the refrigerator 100 is generated according to the following. In other words, the driving plan generation unit 220 is a learning function unit that learns the usage pattern of the refrigerator 100 by the user U. In this application, "learning" broadly means updating past decisions based on new information.

In this embodiment, the driving plan generation unit 220 generates a driving plan for the next day of the same day of the week based on usage status information of the same day of the week in the past two weeks. For example, the driving plan generation unit 220 generates a driving plan for the next Monday based on the usage status information of the previous Monday and the Monday before the previous. The same applies to Tuesday to Sunday.

In this embodiment, the operation plan for refrigerator 100 is a plan that defines a time period in which refrigerator 100 performs normal operation and a time period in which refrigerator 100 performs special operation. The special operation is an operation that reduces the power consumption of refrigerator 100. In this embodiment, the special operation includes a first special operation (eco-operation) and a second special operation (pre-cooling operation). Note that an example in which the first special operation is executed based on the number of times the door is opened and closed will be described below. Alternatively/in addition to this, the first special operation may be executed based on the door opening time.

(Normal operation)
The normal operation is, for example, the operation set in the initial settings of the refrigerator 100. For example, the normal operation is an operation based on the assumption that the refrigerator 100 is used by the user U (for example, the door 20 is opened and closed). That is, the normal operation is an operation in which a relatively low set temperature (target temperature) is set so that the temperature rise in the storage room 30 can be suppressed to a certain level or less even when the door 20 is opened or closed.

(1st special operation)
In the first special operation, the set temperature (target temperature) of the storage room 30 is increased compared to the normal operation during a time period when the number of openings and closings of the door 20 is estimated to be small, and the operation of the cooling unit 130 is suppressed. This is an operation that reduces power consumption. For example, the first special operation increases the operating frequency of the compressor, the rotational speed of the first blower, or the rotational speed of the second blower by increasing the set temperature of the storage room 30 by 1°C or 2°C compared to the normal operation. lower.

In the present embodiment, the operation plan generation unit 220 determines that the number of times the door 20 has been opened and closed in a predetermined unit time (for example, one hour) is equal to or less than a predetermined number of times (for example, five times or less) during the same time period on the same day of the week in the past two weeks. In some cases, the first special operation is executed at the same time on the same day of the week next time. On the other hand, if there is a day in which the number of openings and closings of the door 20 in the predetermined unit time exceeds the predetermined number of times in the same time slot on the same day of the week in the past two weeks, the operation plan generation unit 220 generates a schedule for the same day of the same week next time. The first special operation is not executed during the time period, and normal operation is performed. Below, the first special driving may be referred to as "eco-driving".

Note that the number of times the door 20 is opened and closed refers to, for example, all the doors 20 included in the refrigerator 100 (refrigerator compartment door 21, vegetable compartment door 22, ice making compartment door 23, small freezer compartment door 24, and main freezer compartment door 25). ) is the total value of the number of times the door is opened and closed. Alternatively, the number of times the door 20 is opened and closed may be the total number of times that typical specific doors (for example, the refrigerator compartment door 21, the vegetable compartment door 22, and the main freezer compartment door 25) are opened and closed.

(Second special operation)
In the second special operation, when a large temperature rise (temperature rise exceeding a threshold value) is expected in the storage room 30, the temperature of the storage room 30 is lowered in advance (performing so-called cooling). This is an operation that suppresses a decrease in cooling efficiency (COP: Coefficient Of Performance) by cutting the peak of temperature rise in the room 30, and reduces power consumption of the refrigerator 100. For example, the second special operation is performed for a predetermined unit time in which it is estimated that there is a large temperature rise in the specific store room 30, and for the predetermined unit time and the predetermined unit time immediately before the predetermined unit time. The set temperature (target temperature) is set lower than in normal operation, and the temperature of the specific storage chamber 30 is lowered in advance. For example, in the second special operation, the set temperature of the storage room 30 is lowered by 1° C. or 2° C. compared to the normal operation, so that the operating frequency of the compressor, the rotational speed of the first blower, or the rotational speed of the second blower is reduced. increase.

In the present embodiment, when a large temperature rise is detected in the storage room 30 during the same time period on the same day of the week in the past two weeks, the operation plan generation unit 220 generates The second special operation is executed during the time period. On the other hand, if there is a day in which a large temperature rise is not detected in the storage room 30 during the same time period on the same day of the week in the past two weeks, the operation plan generation unit 220 does not perform the second special operation on the same day of the week next time, Perform normal operation or first special operation. Below, the second special operation may be referred to as "precooling operation."

In the present embodiment, the operation plan for the refrigerator 100 is a plan that specifies which of the normal operation, the first special operation, and the second special operation will be performed every predetermined unit time (for example, every hour). Note that, when the execution schedule of the first special operation and the execution schedule of the second special operation overlap in the same time period, the operation plan generation unit 220 sets the second special operation with priority.

FIG. 5 is a diagram showing an example of a driving plan created by the driving plan generation unit 220. The example shown in FIG. 5 shows a case where a driving plan for the next Monday is generated based on the usage status information of the previous Monday and the Monday before the previous.

In the example shown in Figure 5, (A) for each time period from 0:00 to 6:00, the number of times the door was opened and closed on the previous Monday and the day before the previous Monday was less than the predetermined number of times, and no large temperature rise was detected. , is assigned as the first special operation time slot as the operation plan for the next Monday. (B) For each time period from 6:00 to 8:00, a large temperature rise was detected between 7:00 and 8:00 on the previous Monday and the Monday before, so a second special operation will be implemented as the operation plan for the next Monday. Assigned as a time period. (C) During the time period from 8:00 to 9:00, no large temperature rise was detected on the previous Monday and the Monday before the previous, but there are days when the door was opened and closed more than the specified number of times, so the operation plan for the next Monday This will be assigned as the time period for normal operation. (D) For each time period from 9:00 to 11:00, the number of times the door was opened and closed on the previous Monday and the day before the previous Monday was less than the predetermined number of times, and no large temperature rise was detected, so the operation plan for the next Monday Allotted as the implementation time period for the first special operation.

<3.3 Control command output section>
Control command output unit 230 transmits a control command according to the driving plan generated by driving plan generating unit 220 to refrigerator 100. For example, the control command output unit 230 transmits a control command regarding the next predetermined unit time to the refrigerator 100 every predetermined unit time (for example, every hour). In this embodiment, the control command includes any one of a normal operation execution command, a first special operation execution command, and a second special operation execution command.

<3.4 Implementation rate calculation section>
The implementation rate calculation unit 240 calculates the implementation rate of the special operation based on the execution result accumulation information 282. Below, the implementation rate of special driving may be referred to as "eco-driving rate." The eco-driving rate is calculated based on the following formula, for example. Note that the "number of blocks" means the number of predetermined unit times in which each operation is performed.

Eco-driving rate [%] = (Number of blocks for eco-driving + pre-cooling operation / (Number of blocks for eco-driving + normal operation + pre-cooling operation)) × 100 ... (Formula 1)

In this embodiment, the eco-driving rate is not calculated during a time period in which no past data exists due to poor communication. In other words, uncertain elements are not included in the population. Furthermore, the eco-driving rate is the driving rate during the time period for which data exists for the current day. That is, the eco-driving rate is calculated based on data from the current day (for example, the execution result accumulation information 282 accumulated from midnight until the present). Note that "data after the current day" is not limited to data after midnight, but may be data after another reference time on the current day (for example, data after 1:00 am). Two examples of calculating the eco-driving rate are shown below.

<Calculation example 1>
When the current time is 22:00, if there are 10 blocks in eco-operation, 10 blocks in normal operation, 2 blocks in pre-cooling operation, and 0 blocks offline,
Eco-driving rate [%] = 12 blocks/22 blocks = 55%

<Calculation example 2>
When the current time is 10 o'clock, if there are 9 blocks in eco operation, 1 block in normal operation, 0 blocks in pre-cooling operation, and 0 blocks in offline mode,
Eco-driving rate [%] = 9 blocks/10 blocks = 90%

<3.5 Display information output section>
The display information output unit 250 generates information to be displayed on the display screen 301a of the terminal device 300 (hereinafter referred to as “display information”), and transmits the generated display information to the terminal device 300.

Note that a black frame indicated by the reference numeral 301a shown in FIG. 7 indicates the content that is displayed on the display screen 301a of the display device 301 at one time.

In this embodiment, the display control unit 330 causes the power saving performance display screen D1 to display an operation unit B1, an operation performance display area R1, a door opening/closing frequency display area R2, and a door opening/closing history display area R3. In this embodiment, the display control unit 330 displays the driving performance display area R1, the door opening/closing frequency display area R2, and the door opening/closing history display area R3 on one screen (the same screen). In this application, "displaying on one screen" means "displaying on a series of screens." In other words, "displaying on one screen" is not limited to displaying on a screen that can be viewed at once (for example, within the display screen 301a), but also when a portion of the screen that can be viewed at once is hidden. This may also include a case where the images are displayed in order by scrolling from the original state.

<5.1 Operation section>
The operation unit B1 accepts an operation to change the date to which display information displayed on the power saving performance display screen D1 corresponds. For example, the operation section B1 includes a first operation section B1a and a second operation section B1b. When the first operation unit B1a is operated (for example, tapped) by the user U, display information (driving record, number of door opening/closing times, door opening/closing history, etc.) corresponding to the date one day before the currently displayed date is displayed. Ru. On the other hand, when the second operation unit B1b is operated (for example, tapped) by the user U, display information corresponding to a date one day after the currently displayed date is displayed. The screen displayed when the operation unit B1 is operated will be described later.

That is, the implementation rate display area R1a displays the implementation rate of special driving calculated based on data from that day onwards. In the example shown in FIG. 7, the implementation rate of special operation based on data from 0:00 to 13:00 on May 17th is displayed. Note that the example shown in FIG. 7 is the content displayed on the display screen 301a at 13:00 on May 17th. That is, in the example shown in FIG. 7, the period after 14:00 relates to the future.

(driving history display area)
The driving history display area R1b displays the types of driving performed from early morning to the present day. For example, the type of driving is displayed by a time bar 401 on a chronological basis. The time bar 401 indicates the type of operation performed in each predetermined unit time by color-coding, for example. In the example shown in Fig. 7, the first special driving (eco driving) is performed from 0:00 to 3:00, and from 3:00 to 4:00 there is no data due to communication interruption (offline), and from 4:00 to 6:00. The first special operation (eco-driving) is carried out until 1. This is a case where special driving (eco-driving) is performed and normal driving is performed from 11:00 to 13:00.

The information indicating the type of driving displayed in the driving history display area R1b (for example, the time bar 401) is an example of the "execution result of the special driving", and is an example of the "information indicating the implementation time period in which the special driving was executed". This is an example. In the example shown in FIG. 7, the first special operation is performed from 0:00 to 3:00, from 4:00 to 6:00, and from 9:00 to 11:00. The second special operation was conducted from 6:00 to 8:00.

The driving history display area R1b displays a special display 402 in association with the time series of the time bar 401. The special display 402 is a display indicating that a large temperature rise exceeding a threshold value was predicted in generating the driving plan (a large temperature rise was detected on the same day of the week in the past two weeks). The special display 402 is displayed in association with the time when a large temperature rise is expected in the above-mentioned time series.

<5.3 Door opening/closing count display area>

In the example shown in FIG. 7, the number of times the refrigerator door 21 is opened and closed, the number of times the vegetable compartment door 22 is opened and closed, and the number of times the freezer door 20C is opened and closed are classified and displayed as numerical values. Further, the total number of times these doors (refrigerator compartment door 21, vegetable compartment door 22, freezer door 20C) are opened and closed is displayed as a numerical value.

<5.4 Door opening/closing history display area R3>
The door opening/closing history display area R3 displays the number of door openings/closings from early morning to the present day in the form of a bar graph 411. In the example shown in FIG. 7, the total number of times the doors 20 (refrigerator compartment door 21, vegetable compartment door 22, freezer door 20C) are opened and closed is displayed every predetermined unit time (for example, one hour). Further, the breakdown of the number of times the refrigerator door 21 is opened and closed, the number of times the vegetable compartment door 22 is opened and closed, and the number of times that the freezer door 20C is opened and closed is displayed for each predetermined unit time (for example, one hour). That is, the display control unit 330 displays information indicating the usage status of the refrigerator 100 such as information indicating the usage status of the refrigerator compartment 31 (for example, the number of times the refrigerator compartment door 21 is opened/closed) and information indicating the usage status of the vegetable compartment 32 ( For example, information indicating the usage status of the freezer compartment 30C (number of times the freezer door 20C is opened and closed) is displayed separately.

The number of door opening/closing times displayed in the door opening/closing history display area R3 is an example of "information indicating the usage status of the refrigerator detected by the refrigerator." Note that the door opening/closing history display area R3 may display the door opening time instead of/in addition to the number of door openings/closings. The number of door opening/closing times or the door opening time is an example of "information regarding door opening/closing."

FIG. 8 is a diagram showing the correspondence between the driving history display area R1b and the door opening/closing history display area R3. In this embodiment, the display control unit 330 displays the execution result of the special operation and the information indicating the usage status of the refrigerator 100 in the same chronological order. "Display in the same time series" means, for example, that the unit time length (interval) L of the time axes included in the graphs is the same, and this may also apply even if the graphs or figures are separate. .

In the example shown in FIG. 8, a time bar 401 indicating the type of driving in the driving history display area R1b and a bar graph 411 indicating the number of door openings and closings in the door opening/closing history display area R3 are displayed in the same chronological order. In the present embodiment, the driving history display area R1b and the door opening/closing history display area R3 are arranged so that the time on the time axis included in the driving history display area R1b (for example, the time included in the time bar 401) and the door opening/closing history display area R3 are They are arranged so that the times on the included time axes (for example, the times included in the bar graph 411) match.

Note that the content displayed in the driving history display area R1b and the content displayed in the door opening/closing history display area R3 may be displayed in one graph. Further, the door opening/closing frequency display area R2 may be omitted, and the driving history display area R1b and the door opening/closing history display area R3 may be arranged adjacent to each other.

<5.5 Display of past power saving results>
FIG. 9 is a diagram illustrating an example of a power saving performance display screen D1 showing past power saving performance. The power saving performance display screen D1 is displayed by operating the first operating section B1a shown in FIG. 7, for example.

<6. Control flow>
Next, the flow of control will be explained.
FIG. 10 is a sequence diagram showing the flow of control. FIG. 10 assumes that usage state accumulation information 281 for the past two weeks of refrigerator 100 is accumulated in storage unit 280 of server 200.

First, the operation plan generation unit 220 of the server 200 analyzes the lifestyle pattern of the user U (the usage pattern of the refrigerator 100) based on the usage state accumulation information 281 of the refrigerator 100 for the past two weeks stored in the storage unit 280, An operation plan for the refrigerator 100 is generated according to the lifestyle pattern of the user U (S101). Next, the control command output unit 230 of the server 200 transmits a control command regarding the next predetermined unit time according to the operation plan to the refrigerator 100 every predetermined unit time (for example, every hour) (S102). When receiving the control command from the server 200, the control unit 150 of the refrigerator 100 controls the cooling unit 130 of the refrigerator 100 based on the received control command (S103).

For each predetermined unit time, the control unit 150 of the refrigerator 100 collects usage state information (for example, door opening/closing information 181 and temperature rise information 182) indicating the usage state of the refrigerator 100 detected during the predetermined unit time, and the predetermined information. Execution result information 183 indicating the operation details of refrigerator 100 during a unit time is transmitted to server 200 (S104). The server 200 accumulates the usage state information received from the refrigerator 100 as the usage state accumulation information 281, and also accumulates the execution result information 183 received from the refrigerator 100 as the execution result accumulation information 282 (S105).

When the information acquisition unit 310 of the terminal device 300 receives an operation by the user U to display the power saving performance display screen D1 on the display screen 301a (S111), the information acquisition unit 310 of the terminal device 300 transmits a display information transmission request to the server 200 (S112). When receiving a display information transmission request, the information output unit 250 of the server 200 generates display information based on the latest usage status accumulation information 281 and execution result accumulation information 282 (S113), and sends the generated display information to the terminal. The information is transmitted to the device 300 (S114). When the display information is acquired by the information acquisition unit 310, the display control unit 330 of the terminal device 300 causes the usage state information, execution result information 183, and special operation implementation rate included in the display information to be displayed on one screen. (S115).

<7. Advantages>
As a comparative example, consider a terminal device that displays the time period of whether or not a refrigerator is in energy-saving operation and the degree of energy-saving. With such a terminal device, even if it is possible to understand that the refrigerator has been operated in an energy-saving manner, due to the lack of other information sources, it may not be possible to fully support the user's energy-saving awareness. Sometimes it is difficult to take concrete action.

On the other hand, in the present embodiment, the display control unit 330 of the terminal device 300 combines the execution result of the special operation of the refrigerator 100 to reduce power consumption and the information indicating the usage state of the refrigerator 100 detected by the refrigerator 100 into one. display on one screen. According to such a configuration, it is possible to support the energy saving consciousness of the user U, and it becomes easier for the user U to take the next specific action. For example, the user U can easily take specific actions such as ``reducing the number of times the door is opened and closed'' and ``let hot food cool before putting it in.'' Thereby, user U's convenience can be improved.

Here, since the lifestyle habits of users vary widely, we gave direct advice to user U such as "Please reduce the number of times you open and close the door" and "Please let hot food cool before putting it in." In this case, it may not match the user U's wishes, and the user U may find it bothersome. On the other hand, according to the configuration of this embodiment, information on the refrigerator 100 side, such as the number of times the door is opened and closed and temperature rise, is written in an easy-to-understand manner on the display that feeds back the results of the energy-saving operation, so that the user U can freely decide on improvements. We can provide information on how you can help and support energy saving awareness.

In this embodiment, the execution result of the special operation includes information indicating the implementation time period in which the special operation was executed. According to such a configuration, it is possible to easily know in which time period the special operation was performed and in which time period the special operation was not performed while comparing the usage state of the refrigerator 100. This makes it easier for the user U to take the next specific action.

In this embodiment, the display control unit 330 displays the execution result of the special operation and the information indicating the usage state in the same chronological order. According to such a configuration, it becomes easier to understand the correspondence between the usage state of the refrigerator 100 and the execution result of the special operation. This makes it easier for the user U to take the next specific action.

In this embodiment, the display control unit 330 includes information indicating the usage status of the first storage unit (refrigeration compartment 31 or vegetable compartment 32) and information indicating the usage status of the second storage unit (freezer compartment 30C). Information indicating usage status is displayed separately. According to such a configuration, it becomes easier to understand the relationship between the opening and closing of each door 20 and the execution result of the special operation. This makes it easier for the user U to take the next specific action.

In this embodiment, the display control unit 330 displays the past execution results of the special operation and information indicating the past usage status of the refrigerator 100 on one screen. According to such a configuration, the user U can check the improvement effect based on past execution results and past usage conditions.

In this embodiment, the display control unit 330 displays on one screen the execution time period in which the special operation was executed as the execution result of the special operation and the implementation rate of the special operation. According to such a configuration, by digitizing the graph of the execution result of the special operation, it is possible to support the user U who wants to check the situation at a glance.

In this embodiment, the implementation rate of special driving is calculated based on data from that day onwards. Here, since the first special driving (eco-driving) is the norm during the night, special driving is performed based on data from that day onwards, compared to calculating the implementation rate of special driving based on 24-hour data. When the rate is calculated, a relatively high value is calculated as the implementation rate of special operation. Therefore, user U can easily maintain motivation to save energy.

(Modified example)
FIG. 11 is a diagram illustrating an example of a power saving performance display screen D1 according to a modification of the first embodiment. In this modification, the display control unit 330 displays a temperature history display area R4 instead of/in addition to the door opening/closing history display area R3.

The temperature history display area R4 displays the temperature history of the storage room 30 from early morning to the present day. In the example shown in FIG. 11, the temperature history of the refrigerator compartment 31 and the temperature history of the main freezing compartment 35 are displayed separately. The operating unit B2 is an operating unit that switches between displaying the temperature history of the refrigerator compartment 31 and displaying the temperature history of the main freezing compartment 35. Specifically, when the first operation part B2a is operated (for example, tapped), the temperature history of the refrigerator compartment 31 is displayed. On the other hand, when the second operation part B2b is operated (for example, tapped), the temperature history of the main freezing compartment 35 is displayed. The temperature history of the refrigerator compartment 31 or the main freezer compartment 35 is an example of "information indicating the usage state of the refrigerator detected by the refrigerator." The temperature history of the refrigerator compartment 31 is an example of "information indicating the usage status of the refrigerator compartment 31." The temperature history of the main freezing compartment 35 is an example of "information indicating the usage status of the freezing compartment 30C".

According to such a configuration, similarly to the first embodiment, it is possible to support the energy saving consciousness of the user U, and it becomes easier for the user U to take the next specific action.

(Second embodiment)
Next, a second embodiment will be described. The second embodiment differs from the first embodiment in that the driving performance display area R1 and the door opening/closing history display area R3 move in conjunction with each other in response to a predetermined operation by the user U. The configuration other than those described below is the same as the configuration of the first embodiment.

FIG. 12 is a diagram showing an example of the power saving performance display screen D1 of the second embodiment. In the present embodiment, the display control unit 330 performs a predetermined operation by the user U to display information regarding a different time period in chronological order regarding either the execution result of the special operation or the information indicating the usage status of the refrigerator 100. If accepted, the execution result of the special operation and the information indicating the usage state are changed and displayed in conjunction with each other in chronological order. This content will be explained below.

For example, the driving history display area R1b is displayed in relatively large characters, and 24 hours' worth of information cannot fit on the display screen 301a. For example, a part of the time bar 401 does not fit into the display screen 301a and is not displayed. In this embodiment, the driving history display area R1b includes an operation part B3a that can accept a swipe operation by the user U. The swipe operation is an operation in which a finger is slid in a direction parallel to the time axis in order to display a hidden portion of the time bar 401. An operation on the operation unit B3a is accepted by the operation reception unit 320.

Similarly, the door opening/closing history display area R3 is displayed in relatively large characters, and 24 hours' worth of information cannot fit on the display screen 301a. For example, the bar graph 411 for some time periods does not fit on the display screen 301a and is not displayed. In this embodiment, the door opening/closing history display area R3 includes an operation unit B3b that can accept a swipe operation by the user U. The swipe operation is an operation in which a finger is slid along a direction parallel to the time axis in order to display a hidden portion of the bar graph 411. The operation on the operation unit B3b is accepted by the operation reception unit 320.

In the present embodiment, when the user U's swipe operation is accepted on the operation unit B3a of the driving history display area R1b, the display control unit 330 controls the display content of the driving history display area R1b and the door opening/closing history display area R3. Change the display contents in chronological order. "Linked in chronological order" means maintaining a correspondence relationship in chronological order. For example, when the user U's swipe operation is accepted on the operation unit B3a of the driving history display area R1b, the display control unit 330 changes the display content of the driving history display area R1b to slide and displays the time bar 401. The hidden part of the bar graph 411 is displayed, and the display contents of the door opening/closing history display area R3 are changed to slide to display the hidden part of the bar graph 411.

In addition, when the user U's swipe operation is accepted on the operation unit B2b of the door opening/closing history display area R3, the display control unit 330 controls the display content of the driving history display area R1b and the display of the door opening/closing history display area R3. Changes are made in conjunction with the content in chronological order. For example, when the user U's swipe operation is accepted on the operation unit B2b of the door opening/closing history display area R3, the display control unit 330 changes the display content of the driving history display area R1b to slide and displays the time bar. 401 is displayed, and the display content of the door opening/closing history display area R3 is changed to slide to display the hidden part of the bar graph 411.

According to such a configuration, it becomes easy to compare the content displayed in the driving history display area R1b and the content displayed in the door opening/closing history display area R3. As a result, the user U's effort is reduced and analysis becomes easier for each time period.

(Third embodiment)

In this embodiment, the storage compartment 30 in the refrigerating temperature range (refrigerating compartment 31 and the vegetable compartment 32) and the storage compartment 30 in the freezing temperature range (freezing compartment 30C) are independently operated in the normal operation and the first special operation. , or the second special operation is set. The power saving performance display screen D1 includes information indicating the execution results and usage status of the special operation regarding the storage room 30 in the refrigerating temperature range, and information indicating the execution result and usage status of the special operation regarding the storage compartment 30 in the freezing temperature range. are displayed separately.

In the present embodiment, the power saving performance display screen D1 includes an operation unit B4 that can switch between information regarding the storage compartment 30 in the refrigerating temperature range and information regarding the storage compartment 30 in the freezing temperature range. The operating section B4 includes a first operating section B4a and a second operating section B4b. When the first operation part B4a is operated (for example, tapped), an operation performance display area R1, a door opening/closing frequency display area R2, and a door opening/closing history display area R3 regarding the storage room 30 in the refrigeration temperature range are displayed. On the other hand, when the second operation part B4b is operated (for example, tapped), an operation record display area R1, a door opening/closing frequency display area R2, and a door opening/closing history display area R3 regarding the storage room 30 in the freezing temperature range are displayed. .

According to such a configuration, it becomes easier to understand the relationship between the usage status of each storage chamber 30 and the execution result of the special operation. This makes it easier for the user U to take the next specific action.

(Fourth embodiment)
Next, a fourth embodiment will be described. The fourth embodiment differs from the first embodiment in that the door opening/closing frequency display area R2 can be downsized or omitted. The configuration other than those described below is the same as the configuration of the first embodiment.
