[0025] The server 400 can communicate with the terminal device 200 via the network N. The server 400 can also communicate with the refrigerator 100 via the network N.

[0026] Next, the notification control system 1 will be described in more detail with reference to Figures 1 and 2. Figure 2 shows a block diagram of the notification control system 1 according to this embodiment.

[0027] The refrigerator 100 includes a cooling unit 60, a moving object detection unit 101, an opening / closing detection unit 102, a first communication unit 103, a second communication unit 104, a memory unit 105, a clock unit 106, and a control unit 150.

[0028] The cooling section 60 cools the first storage space 10a of the first refrigeration compartment 10, the second storage space 20a of the second refrigeration compartment 20, and the third storage space 30c of the freezer compartment 30.

[0029] The cooling unit 60 has a refrigerant, a refrigerant pipe, a compression unit, a condensation unit, an expansion unit, an evaporation unit, a fan, a cold air passage, and a damper. The refrigerant transports heat. The refrigerant pipe guides the refrigerant. The refrigerant pipe connects the compression unit, the condensation unit, the expansion unit, and the evaporation unit, and the refrigerant circulates between the compression unit, the condensation unit, the expansion unit, and the evaporation unit.

[0030] The compression section compresses the refrigerant vaporized in the evaporation section, making it high temperature and high pressure. The condensation section dissipates heat from the gas that has become high temperature and high pressure in the compression section, making it a liquid refrigerant at room temperature and high pressure. The expansion section reduces the pressure on the liquid refrigerant at room temperature and high pressure, making the liquid refrigerant low temperature and low pressure. The evaporation section vaporizes the low temperature and low pressure liquid refrigerant. When the refrigerant vaporizes, it absorbs heat from the surrounding air and cools the surrounding air. The fan blows the cooled air into the cold air passage. The cold air passage guides the cold air to the first refrigerator compartment 10, the second storage space 20a of the second refrigerator compartment 20, and the third storage space 30c of the freezer compartment 30.

[0031] The mobile object detection unit 101 detects the presence of a mobile object. The mobile object detection unit 101 detects the presence of the mobile object and outputs a detection signal indicating that the mobile object has been detected to the control unit 150. The mobile object is, for example, a human being such as a user. The mobile object detection unit 101 includes a human presence sensor and a camera. The human presence sensor is, for example, an infrared sensor. The camera captures an image of the mobile object and outputs an image capture signal as a detection signal to the control unit 150.

[0032] The open / close detection unit 102 is an open / close sensor that detects the opening and closing operation of the door unit. The open / close detection unit 102 detects that the door unit is opened, and outputs a detection signal to the control unit 150. The open / close detection unit 102 also detects that the door unit is closed, and outputs a detection signal to the control unit 150.

[0033] Specifically, for example, the open / close detection unit 102 is disposed at the opening of the first refrigerator compartment 10. The open / close detection unit 102 detects that the first door unit 11 is opened, and outputs a detection signal to the control unit 150. The open / close detection unit 102 also detects that the first door unit 11 is closed, and outputs a detection signal to the control unit 150.

[0034] Furthermore, the refrigerator 100 may have a plurality of open / close detection units 102. For example, the refrigerator 100 has three open / close detection units 102. One of the three open / close detection units 102 detects, for example, the open / close operation of the first door unit 11. Another of the three open / close detection units 102 detects, for example, the open / close operation of the second door unit 21. Yet another of the three open / close detection units 102 detects, for example, the open / close operation of the third door unit 31.

[0035] The first communication unit 103 is capable of wired or wireless communication with the server 400. The first communication unit 103 transmits and receives data to and from the server 400. The first communication unit 103 corresponds to an example of a "communication unit".

[0036] The first communication unit 103 communicates with the server 400 via the network N, for example. The first communication unit 103 may include, for example, a network interface controller (NIC) that communicates according to a predetermined communication protocol. The first communication unit 103 may also include, for example, a wireless communication module. In a state in which communication with the server 400 is permitted by the user, the first communication unit 103 communicates with the server 400. In addition, in a state in which communication with the server 400 is not permitted by the user, the first communication unit 103 does not communicate with the server 400.

[0037] The second communication unit 104 communicates with the terminal device 200. The second communication unit 104 includes a wireless communication module that complies with a short-range wireless communication standard. The short-range wireless communication standard is, for example, Bluetooth (registered trademark). For example, the second communication unit 104 and the terminal device 200 are associated with each other, whereby the refrigerator 100 and the terminal device 200 are linked.

[0038] The storage unit 105 stores data and computer programs. For example, the storage unit 105 temporarily stores data necessary for each process of the control unit 150, and stores setting data for the cooling unit 60. The storage unit 105 includes storage devices (main storage device and auxiliary storage device), and includes, for example, a memory and a hard disk drive. The storage unit 105 may include removable media.

[0039] The clock unit 106 keeps track of time.

[0040] The control unit 150 includes a processor such as a CPU (Central Processing Unit) or an ASIC (Application Specific Integrated Circuit), and a storage device. For example, the control unit 150 receives various signals from each element of the refrigerator 100, and controls each element of the refrigerator 100 based on the received signals. Specifically, the control unit 150 controls each element of the refrigerator 100, such as the cooling unit 60, the moving object detection unit 101, the open / close detection unit 102, the first communication unit 103, the second communication unit 104, the storage unit 105, and the clock unit 106.

[0042] The notification unit 201 notifies the user that the refrigerator 100 can communicate with the server 400. The notification unit 201 includes a display unit 210 and a speaker 220.

[0043] The display unit 210 displays various images. The display unit 210 is, for example, a liquid crystal display (LCD).

[0044] The speaker 220 outputs sound. For example, the speaker 220 outputs voice.

[0045] The third communication unit 203 is capable of wired or wireless communication with the server 400. The third communication unit 203 transmits and receives data to and from the server 400. The third communication unit 203 communicates with the server 400 via, for example, a network N. The third communication unit 203 may include, for example, a network interface controller (NIC) that performs communication according to a predetermined communication protocol. Furthermore, the third communication unit 203 may include, for example, a wireless communication module.

[0046] The fourth communication unit 204 communicates with the refrigerator 100. The fourth communication unit 204 includes a wireless communication module that complies with a short-range wireless communication standard. The short-range wireless communication standard is, for example, Bluetooth (registered trademark). For example, the fourth communication unit 204 and the second communication unit 104 are associated with each other, thereby linking the refrigerator 100 and the terminal device 200. When the refrigerator 100 and the terminal device 200 are linked, for example, the terminal device 200 can wirelessly operate the refrigerator 100 via the second communication unit 104 or the fourth communication unit 204.

[0047] The storage unit 205 stores data and computer programs. For example, the storage unit 205 temporarily stores data necessary for each process of the control unit 250, and stores setting data for the display unit 210 and the speaker 220. The storage unit 205 includes storage devices (main storage device and auxiliary storage device), and includes, for example, a memory and a hard disk drive. The storage unit 205 may include removable media.

[0048] The control unit 250 includes a processor such as a CPU or an ASIC, and a storage device. For example, the control unit 250 receives various signals from each element of the terminal device 200, and controls each element of the terminal device 200 based on the received signals. Specifically, the control unit 250 controls each element of the terminal device 200, such as the display unit 210, the speaker 220, the third communication unit 203, the fourth communication unit 204, and the storage unit 205.

[0049] The server 400 includes a fifth communication unit 403, a storage unit 405, and a control unit 450.

[0050] The fifth communication unit 403 is capable of wired or wireless communication with the refrigerator 100 and the terminal device 200. The fifth communication unit 403 transmits and receives data between the refrigerator 100 and the terminal device 200. The fifth communication unit 403 communicates with the refrigerator 100 and the terminal device 200, for example, via a network N. The fifth communication unit 403 may include, for example, a network interface controller (NIC) that communicates according to a predetermined communication protocol. The fifth communication unit 403 may also include, for example, a wireless communication module.

[0051] The storage unit 405 stores data and computer programs. For example, the storage unit 405 temporarily stores data necessary for each process of the control unit 450 and stores function information of the refrigerator 100. The storage unit 405 includes storage devices (main storage device and auxiliary storage device), and includes, for example, a memory and a hard disk drive. The storage unit 405 may include removable media.

[0052] The control unit 450 includes a processor, such as a CPU or an ASIC, and a storage device. For example, the control unit 450 controls the fifth communication unit 403 to transmit function information to the terminal device 200.

[0053] The process executed by the control unit 150 of the refrigerator 100 will be described in detail with reference to FIG.

[0054] As shown in FIG. 2, the control unit 150 includes a notification control unit 151.

[0055] The notification control unit 151 executes notification control. The notification control indicates that the notification unit 201 of the terminal device 200 is controlled to notify that the refrigerator 100 can communicate with the server 400. Specifically, the notification control indicates that the display unit 210 of the terminal device 200 is controlled to display an image indicating that the refrigerator 100 can communicate with the server 400. Also, specifically, the notification control indicates that the speaker 220 of the terminal device 200 is controlled to output a sound indicating that the refrigerator 100 can communicate with the server 400. Note that the notification control may indicate that the display unit 210 is controlled to display an image indicating that the refrigerator 100 can communicate with the server 400, and that the speaker 220 is controlled to output a sound indicating that the refrigerator 100 can communicate with the server 400.

[0056] Specifically, the notification control unit 151 executes notification control to control the notification unit 201 to notify that communication with the server 400 is possible when power is supplied to the refrigerator 100. When starting to supply power to the refrigerator 100, the user plugs the power supply terminal of the refrigerator 100 into an outlet. In other words, the user is near the refrigerator 100. Therefore, when the user is near the refrigerator 100, the notification unit 201 can notify that communication with the server 400 is possible. As a result, the user can be notified that the refrigerator 100 has a communication function. In other words, the user can be efficiently notified that the refrigerator 100 has a communication function, and the user can be prompted to allow communication between the refrigerator 100 and the server 400.

[0057] For example, notification control unit 151, which executes notification control, generates control information for controlling notification unit 201 so that notification unit 201 notifies that it can communicate with server 400. Then, notification control unit 151 causes second communication unit 104 to transmit the control information to fourth communication unit 204 of terminal device 200. Based on the control information received by fourth communication unit 204, control unit 250 controls notification unit 201 so that notification unit 201 notifies that it can communicate with server 400. Therefore, when the user is near refrigerator 100, display unit 210 displays an image indicating that it can communicate with server 400. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400.

[0058] Also, for example, notification control unit 151 that executes notification control generates control information for controlling display unit 210 so that display unit 210 displays an image indicating that it can communicate with server 400. Then, notification control unit 151 causes second communication unit 104 to transmit the control information to fourth communication unit 204 of terminal device 200. Based on the control information received by fourth communication unit 204, control unit 250 controls display unit 210 so that display unit 210 displays an image indicating that it can communicate with server 400. Therefore, when the user is near refrigerator 100, display unit 210 displays an image indicating that it can communicate with server 400. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400.

[0059] Furthermore, for example, notification control unit 151, which executes notification control, generates control information for controlling speaker 220 so that speaker 220 outputs a sound indicating that communication with server 400 is possible. Then, notification control unit 151 causes second communication unit 104 to transmit the control information to fourth communication unit 204 of terminal device 200. Based on the control information received by fourth communication unit 204, control unit 250 controls speaker 220 so that speaker 220 outputs a sound indicating that communication with server 400 is possible. Therefore, when the user is near refrigerator 100, speaker 220 outputs a sound indicating that communication with server 400 is possible. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400.

[0060] The notification control unit 151 executes notification control in a state in which communication between the first communication unit 103 and the server 400 is not permitted. In other words, when the function information cannot be notified to the user, the notification control unit 151 executes notification control to control the notification unit 201 to notify that communication with the server 400 is possible. As a result, the user can be prompted to permit communication between the refrigerator 100 and the server 400. In other words, when communication between the first communication unit 103 and the server 400 is not permitted and power is supplied to the refrigerator 100, the notification control unit 151 executes notification control to control the notification unit 201 to notify that communication with the server 400 is possible.

[0061] The storage unit 105 also stores information indicating that power has been supplied to the refrigerator 100. That is, the notification control unit 151 obtains information indicating that power has been supplied to the refrigerator 100 from the storage unit 105.

[0062] Furthermore, the notification control unit 151 determines whether or not the end time of the notification control has arrived based on the timer unit 106. The end time is, for example, "10 minutes from the start of the notification control." If the end time has arrived, the notification control unit 151 ends the notification control. If it is not the end time, the notification control unit 151 executes the notification control.

[0063] When communication between the first communication unit 103 and the fifth communication unit 403 of the server 400 is permitted, the notification control unit 151 does not execute notification control. Therefore, it is possible to suppress unnecessary notifications to the user. As a result, it is possible to reduce power consumption required for unnecessary notification control.

[0064] Next, the process executed by the control unit 150 of the third embodiment will be described in detail with reference to Fig. 3. Fig. 3 is a flowchart showing the process executed by the control unit 150 of the third embodiment. As shown in Fig. 3, the process executed by the control unit 150 includes steps S11 to S18.

[0065] In step S11, the notification control unit 151 acquires information indicating that power has been supplied to the refrigerator 100 from the storage unit 105. The process proceeds to step S12.

[0066] In step S12, the notification control unit 151 determines whether or not the first communication unit 103 is permitted to communicate with the server 400. If the first communication unit 103 is permitted to communicate with the server 400 (Yes in step S12), the process ends. If the first communication unit 103 is not permitted to communicate with the server 400 (No in step S12), the process proceeds to step S13.

[0067] In step S13, the notification control unit 151 executes notification control and generates control information for controlling the notification unit 201 so that the notification unit 201 notifies that communication with the server 400 is possible. The process proceeds to step S14.

[0068] In step S14, the notification control unit 151 controls the second communication unit 104 so that the second communication unit 104 transmits the control information to the fourth communication unit 204 of the terminal device 200. The process proceeds to step S15.

[0069] In step S15, the notification control unit 151 judges whether or not information indicating that communication between the refrigerator 100 and the server 400 is permitted has been received from the terminal device 200. If information indicating that communication is permitted has not been received (No in step S15), the process proceeds to step S17. If information indicating that communication is permitted has been received (Yes in step S15), the process proceeds to step S16.

[0070] If the result of step S15 is Yes, in step S16, the notification control unit 151 ends the notification control, and the process ends.

[0071] If the result in step S15 is No, in step S17, the notification control unit 151 determines whether or not it is time to end the notification control. If it is not time to end the notification control (No in step S17), the process returns to step S15. If it is time to end the notification control (Yes in step S17), the process proceeds to step S18.

[0072] If the result of step S17 is Yes, in step S18, the notification control unit 151 ends the notification control, and the process ends.

[0073] [Embodiment 2] Next, a third embodiment of the processing of the control unit 150 will be described with reference to Fig. 1, Fig. 2, and Fig. 4. The second embodiment differs from the present embodiment mainly in that the notification control unit 151 executes notification control based on the detection result of the moving object detection unit 101. The differences between the second embodiment and the present embodiment will be described below.

[0074] The notification control unit 151 of the second embodiment executes notification control to control the notification unit 201 to notify that communication with the server 400 is possible, based on the detection result of the moving object detection unit 101. Therefore, when the user is near the refrigerator 100, the notification unit 201 can notify that communication with the server 400 is possible. As a result, the user can be efficiently notified that the refrigerator 100 has a function for communicating with the server 400.

[0075] Specifically, in a state in which communication between first communication unit 103 and server 400 is not permitted, notification control unit 151 executes notification control to control notification unit 201 to notify that communication with server 400 is possible, based on the detection result of mobile object detection unit 101. Therefore, when the user is near refrigerator 100, notification unit 201 can notify that communication with server 400 is possible. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400. Then, it is possible to urge the user to permit communication between refrigerator 100 and server 400.

[0076] Furthermore, since notification unit 201 notifies that communication with server 400 is possible when mobile object detection unit 101 detects a user, power consumption can be reduced compared to a case in which the notification unit always notifies that communication with server 400 is possible. As a result, power consumption by refrigerator 100 can be reduced while notifying the user that communication with server 400 is possible.

[0077] When the mobile object detection unit 101 detects the user multiple times, the notification control unit 151 executes notification control. Multiple times indicates, for example, an integer equal to or greater than 2. Therefore, the notification unit 201 does not issue a notification every time the user is detected. As a result, it is possible to reduce power consumption required for notification control.

[0078] Generally, a user passes near the refrigerator 100 frequently. Therefore, if the notification unit 201 issues a notification every time the user passes near the refrigerator 100, the power consumption for the notification will be large. Therefore, as in this embodiment, when the mobile object detection unit 101 detects the user multiple times, the notification control unit 151 executes notification control. As a result, the power consumption for the notification can be reduced.

[0079] For example, if the "multiple times" is an integer indicating "100", when the mobile object detection unit 101 detects the user only 100 times, the notification control unit 151 executes notification control. Therefore, every time the number of times the user is detected reaches 100, the notification unit 201 notifies the server 400 that it can communicate with the server 400. In other words, the power consumption required for notification control can be reduced compared to the case where the notification unit 201 notifies the server 400 that it can communicate with the server 400 every time the user is detected.

[0080] The notification control unit 151 executes notification control when a predetermined time has come. Specifically, the notification control unit 151 executes notification control when the mobile object detection unit 101 detects the presence of the user multiple times and the predetermined time has come. For example, in general, a user is often busy in the morning. In other words, when the user is busy, it is difficult to prompt the user to allow communication between the refrigerator 100 and the server 400 even if the notification control unit 151 executes notification control. On the other hand, in the afternoon, the user has time to take a break. Therefore, for example, by setting the predetermined time to a time in the afternoon when the user takes a break, it is possible to efficiently notify the user that the refrigerator 100 has a function to communicate with the server 400. As a result, it is possible to prompt the user to allow communication between the refrigerator 100 and the server 400 while reducing the power consumption required for notification.

[0081] Based on the time measured by clock unit 106, notification control unit 151 determines whether or not a predetermined time has arrived. The predetermined time is, for example, "20:00." If the predetermined time has arrived, notification control unit 151 executes notification control. If the predetermined time has not arrived, notification control unit 151 waits until the predetermined time arrives. The predetermined time may be stored in memory unit 105 before refrigerator 100 is shipped.

[0082] Furthermore, the control unit 150 may determine the predetermined time based on the detection result of the moving object detection unit 101 and the time measured by the clock unit 106. Specifically, for example, based on the detection result of the moving object detection unit 101 and the time measured by the clock unit 106, the control unit 150 stores the time when the moving object detection unit 101 detected the moving object in the storage unit 105. In general, when the moving object detection unit 101 detects a moving object frequently per hour, the user is busy. For example, when the moving object detection unit 101 detects a moving object frequently per hour, the user frequently passes near the refrigerator 100. Therefore, the control unit 150 determines the predetermined time to be a time different from the time when the moving object detection unit 101 detects a moving object frequently per hour.

[0083] The process executed by the control unit 150 of the refrigerator 100 will be described in further detail with reference to Fig. 2. As shown in Fig. 2, the control unit 150 has a change unit 152 and a determination unit 153.

[0084] Change unit 152 changes the content of the notification by notification unit 201 based on the number of times notification control has been executed. Therefore, different notification content can be notified to the user based on the number of times notification control has been executed. As a result, the user can be prompted to allow communication between refrigerator 100 and server 400. Also, it is possible to reduce the amount of notification that the user finds annoying.

[0085] For example, the control information generated by the notification control unit 151 includes a plurality of pieces of function information. The plurality of pieces of function information includes, for example, first to third function information. The first piece of function information is information indicating that the server 400 and the refrigerator 100 communicate with each other to enable the user to use a shopping memo function. The shopping memo function indicates, for example, a purchasing list of ingredients. The second piece of function information is information indicating that the server 400 and the refrigerator 100 communicate with each other to enable the user to use a menu memo function. The menu memo function indicates a list of dishes. The third piece of function information is information indicating that the server 400 and the refrigerator 100 communicate with each other to enable the user to use a message function. The message function indicates a function for sending a message from one user to another user.

[0086] For example, when the notification control is executed once, change unit 152 changes the notification content of notification unit 201. Specifically, change unit 152 changes the notification content to include information indicating that refrigerator 100 can communicate with server 400, the first function information, the second function information, and the third function information. Therefore, notification unit 201 notifies information indicating that refrigerator 100 can communicate with server 400, the first function information, the second function information, and the third function information.

[0087] Specifically, for example, display unit 210 displays an image indicating that refrigerator 100 can communicate with server 400, an image indicating the first function information, an image indicating the second function information, and an image indicating the third function information. Specifically, for example, speaker 220 outputs a sound indicating that refrigerator 100 can communicate with server 400, a sound indicating the first function information, a sound indicating the second function information, and a sound indicating the third function information.

[0088] Furthermore, when the number of times the notification control is executed is an integer equal to or greater than 2, change unit 152 changes the content of the notification by notification unit 201. Specifically, change unit 152 changes the content of the notification to include information indicating that refrigerator 100 can communicate with server 400, and any one of the first function information, the second function information, and the third function information.

[0089] The count of the number of times the notification control has been executed may be reset, for example, when the control unit 150 counts 1000 times. The number of times the notification control has been executed is just an example, and can be set to any number. The count of the number of times the notification control has been executed may be reset, for example, once a month. The timing of resetting the number of times the notification control has been executed is just an example, and can be set to any timing.

[0090] The determination unit 153 determines whether or not the number of times the notification control has been executed exceeds a threshold value. The threshold value is, for example, an integer indicating "100." Specifically, the determination unit 153 determines whether or not the number of times the notification control has been executed exceeds 100 times.

[0091] In this embodiment, when determination unit 153 determines that the number of times notification control has been executed exceeds the threshold, notification control unit 151 does not execute notification control. In general, when the number of times execution exceeds the threshold, the user often does not want communication between server 400 and refrigerator 100. Therefore, it is possible to determine whether or not the user wants communication between server 400 and refrigerator 100. As a result, it is possible to prevent the user from feeling annoyed by unnecessary notifications.

[0092] Furthermore, in this embodiment, the control unit 150 judges whether the terminal device 200 of a user moving near the refrigerator 100 is a terminal device 200 that is linked to the refrigerator 100. If the terminal device 200 is not linked to the refrigerator 100, the control unit 150 controls the second communication unit 104 so that the second communication unit 104 transmits information to the terminal device 200 indicating that the terminal device 200 can be linked to the refrigerator 100. This makes it possible to notify multiple users that the server 400 and the refrigerator 100 can communicate with each other. As a result, the possibility that communication between the server 400 and the refrigerator 100 will be permitted increases.

[0093] The control unit 150 may determine whether or not the user has a terminal device 200 linked to the refrigerator 100, based on the image capture signal output from the mobile object detection unit 101. If the user does not have a terminal device 200 linked to the refrigerator 100, the control unit 150 controls the second communication unit 104 so that the second communication unit 104 transmits to the terminal device 200 information indicating that the terminal device 200 can be linked to the refrigerator 100. This makes it possible to notify multiple users that communication between the server 400 and the refrigerator 100 is possible. As a result, the possibility that communication between the server 400 and the refrigerator 100 will be permitted increases.

[0094] Next, the process executed by the control unit 150 will be described in detail with reference to Fig. 4. Fig. 4 is a flowchart showing the process executed by the control unit 150 of the second embodiment. As shown in Fig. 4, the process executed by the control unit 150 includes steps S101 to S115.

[0095] In step S101, the notification control unit 151 acquires a detection signal indicating that the presence of a user has been detected from the moving object detection unit 101. The process proceeds to step S102.

[0096] In step S102, the notification control unit 151 determines whether or not the mobile object detection unit 101 has detected the user multiple times. If the user has not been detected multiple times (No in step S102), the process returns to step S101. If the user has been detected multiple times (Yes in step S102), the process proceeds to step S103.

[0097] If the answer is Yes in step S102, in step S103, the notification control unit 151 determines whether or not a predetermined time has arrived based on the timer unit 106. If the predetermined time has not arrived (No in step S103), the process repeats step S103. If the predetermined time has arrived (Yes in step S103), the process proceeds to step S104.

[0098] If the answer is Yes in step S103, in step S104, the notification control unit 151 determines whether or not the first communication unit 103 is permitted to communicate with the server 400. If the first communication unit 103 is permitted to communicate with the server 400 (Yes in step S104), the process ends. If the first communication unit 103 is not permitted to communicate with the server 400 (No in step S104), the process proceeds to step S105.

[0099] If the result is No in step S104, in step S105, the notification control unit 151 obtains the number of times the notification control has been executed from the storage unit 105. The process proceeds to step S106.

[0100] In step S106, the determination unit 153 determines whether the number of times the notification control is executed exceeds the threshold. If the number of times the notification control is executed exceeds the threshold (Yes in step S106), the process ends. If the number of times the notification control is executed does not exceed the threshold (No in step S106), the process proceeds to step S107.

[0101] If the result of step S106 is No, in step S107, the change unit 152 changes the content of the notification by the notification unit 201 based on the number of times the notification control has been executed. The process proceeds to step S108.

[0102] In step S108, the notification control unit 151 executes notification control and generates control information for controlling the notification unit 201 so that the notification unit 201 notifies that communication with the server 400 is possible. The process proceeds to step S109.

[0103] In step S109, the notification control unit 151 controls the second communication unit 104 so that the second communication unit 104 transmits the control information to the fourth communication unit 204 of the terminal device 200. The process proceeds to step S110.

[0104] In step S110, the notification control unit 151 determines whether or not information indicating that communication between the refrigerator 100 and the server 400 is permitted has been received from the terminal device 200. If information indicating that communication is permitted has not been received (No in step S110), the process proceeds to step S114. If information indicating that communication is permitted has been received (Yes in step S110), the process proceeds to step S111.

[0105] If the result of step S110 is Yes, in step S111, the notification control unit 151 ends the notification control, and the process ends.

[0106] If the result in step S110 is No, in step S114, the notification control unit 151 determines whether or not it is time to end the notification control. If it is not time to end the notification control (No in step S114), the process returns to step S108. If it is time to end the notification control (Yes in step S114), the process proceeds to step S115.

[0107] If the result of step S114 is Yes, in step S115, the notification control unit 151 ends the notification control, and the process ends.

[0108] [Embodiment 3] Next, a third embodiment of the processing of the control unit 150 will be described with reference to Fig. 1, Fig. 2, and Fig. 5. The third embodiment differs from the present embodiment mainly in that the notification control unit 151 executes notification control based on the detection result of the open / close detection unit 102. The differences between the third embodiment and the present embodiment will be described below.

[0109] The notification control unit 151 of the third embodiment executes notification control to control the notification unit 201 to notify that communication with the server 400 is possible, based on the detection result of the open / close detection unit 102. Therefore, when the user opens at least one of the first door unit 11, the second door unit 21, and the third door unit 31, the user is near the refrigerator 100. Furthermore, when the user closes at least one of the first door unit 11, the second door unit 21, and the third door unit 31, the user is near the refrigerator 100. In other words, when the user is near the refrigerator 100, the notification unit 201 can notify that communication with the server 400 is possible. As a result, the user can be efficiently notified that the refrigerator 100 has a function to communicate with the server 400. Then, the user can be prompted to allow communication between the refrigerator 100 and the server 400.

[0110] Specifically, when communication between first communication unit 103 and server 400 is not permitted, notification control unit 151 executes notification control to control notification unit 201 to notify that communication with server 400 is possible, based on the detection result of open / close detection unit 102. Therefore, when the user is near refrigerator 100, notification unit 201 can notify that communication with server 400 is possible. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400. Then, it is possible to urge the user to permit communication between refrigerator 100 and server 400.

[0111] When the open / close detection unit 102 detects multiple times that one of the openings of the first refrigerator compartment 10, the second refrigerator compartment 20, and the freezer compartment 30 has been opened, or that one of the openings of the first refrigerator compartment 10, the second refrigerator compartment 20, and the freezer compartment 30 has been closed, the notification control unit 151 executes notification control. Multiple times indicates an integer of 2 or more. Therefore, the notification unit 201 does not issue a notification every time a user is detected. As a result, the power consumption required for the notification control can be reduced.

[0112] In addition, the notification control unit 151 of the third embodiment judges whether or not a predetermined time has come based on the clock unit 106 after the open / close detection unit 102 detects that one of the openings of the first refrigerator compartment 10, the opening of the second refrigerator compartment 20, and the opening of the freezer compartment 30 has been opened, or that one of the openings of the first refrigerator compartment 10, the opening of the second refrigerator compartment 20, and the opening of the freezer compartment 30 has been closed. For example, in general, a user is often busy in the morning. That is, when a user is busy, even if the notification control unit 151 executes notification control, it is difficult to prompt the user to allow communication between the refrigerator 100 and the server 400. On the other hand, in the afternoon, the user has time to take a break. Therefore, for example, by setting the predetermined time to a time in the afternoon when the user takes a break, it is possible to efficiently notify the user that the refrigerator 100 has a function to communicate with the server 400. As a result, it is possible to prompt the user to allow communication between the refrigerator 100 and the server 400. As described above, when the opening of the refrigerator compartment is opened or closed and at a specified time, a notification is given to the user to encourage the connection between the refrigerator and the server, which makes the notification effective. This is because the opening of the refrigerator compartment is opened or closed when the user is near the refrigerator, and the specified time or period is not a busy time such as when preparing a meal. Therefore, the user can receive the notification at a time when it is easy for the user to set up the refrigerator to connect to the server.

[0113] Also, the control unit 150 may determine the predetermined time based on the detection result of the open / close detection unit 102 and the time measured by the clock unit 106. Specifically, for example, based on the detection result of the open / close detection unit 102 and the time measured by the clock unit 106, the control unit 150 stores the time at which the open / close detection unit 102 detects the opening or closing of the first door unit 11 in the memory unit 105. Generally, when the door of the refrigerator 100 is opened frequently, the user is busy. For example, when the door of the refrigerator 100 is opened frequently, the user is cooking. Therefore, the control unit 150 determines the predetermined time to be a time different from the time at which the door of the refrigerator 100 is opened frequently.

[0114] Next, the process executed by the control unit 150 of the third embodiment will be described in detail with reference to Fig. 5. Fig. 5 is a flowchart showing the process executed by the control unit 150 of the third embodiment. As shown in Fig. 5, the process executed by the control unit 150 includes steps S201 to S215. Steps S203 to S215 shown in Fig. 5 correspond to steps S103 to S115 of the second embodiment described with reference to Fig. 4. Therefore, the description of steps S203 to S215 will be omitted, and steps S201 to S202 will be described.

[0115] In step S201, the notification control unit 151 acquires a detection signal indicating that the opening is opened or a detection signal indicating that the opening is closed from the open / close detection unit 102. The process proceeds to step S202.

[0116] In step S202, the notification control unit 151 judges whether the open / close detection unit 102 has detected the opening of the opening or the closing of the opening multiple times. If the open / close detection unit 102 has not detected the opening of the opening or the closing of the opening multiple times (No in step S202), the process returns to step S201. If the open / close detection unit 102 has detected the opening of the opening or the closing of the opening multiple times (Yes in step S202), the process proceeds to step S203.

[0117] [Embodiment 4] Next, a fourth embodiment of the present invention will be described with reference to Figs. 3 to 6. The notification control system 1 of the fourth embodiment differs from the notification control system 1 of the first embodiment in that the refrigerator 100 includes a notification unit 50. Below, differences between the fourth embodiment and the first embodiment will be described, and descriptions of parts that overlap with the first embodiment will be omitted. Fig. 6 is a block diagram showing the notification control system 1 according to the fourth embodiment.

[0118] As shown in FIG. 6, the refrigerator 100 includes a cooling unit 60, a moving object detection unit 101, an opening / closing detection unit 102, an alarm unit 50, a first communication unit 103, a second communication unit 104, a memory unit 105, a timing unit 106, and a control unit 150.

[0119] The cooling unit 60 cools the first storage space 10a of the first refrigerator compartment 10, the second storage space 20a of the second refrigerator compartment 20, and the third storage space 30c of the freezer compartment 30. The moving object detection unit 101 detects the presence of a moving object. The opening / closing detection unit 102 is an opening / closing sensor that detects the opening and closing operation of the door unit. The first communication unit 103 is capable of wired or wireless communication with the server 400. The second communication unit 104 communicates with the terminal device 200. The memory unit 105 stores data and computer programs. The clock unit 106 keeps track of the time. The control unit 150 controls each element of the refrigerator 100.

[0120] The notification unit 50 notifies the user that the refrigerator 100 can communicate with the server 400. The notification unit 50 includes a display unit 110 and a speaker 120.

[0121] The display unit 110 displays various images. The display unit 110 is, for example, a liquid crystal display (LCD). The display unit 110 is disposed on the first door unit 11, for example.

[0122] The speaker 120 outputs sound. The speaker 120 is disposed in the first door portion 11, for example.

[0123] The control unit 150 of the fourth embodiment will be described in detail with reference to Fig. 6. As shown in Fig. 6, the control unit 150 includes a notification control unit 151, a change unit 152, and a determination unit 153.

[0124] The notification control unit 151 of the fourth embodiment executes notification control in a state in which communication between the first communication unit 103 and the server 400 is not permitted. Specifically, the notification control of the fourth embodiment indicates control to cause the display unit 110 to display an image indicating that communication with the server 400 is possible. Also, specifically, the notification control indicates control to cause the speaker 120 to output a sound indicating that communication with the server 400 is possible. Note that the notification control may indicate control to cause the display unit 110 to display an image indicating that communication with the server 400 is possible, and control to cause the speaker 120 to output a sound indicating that communication with the server 400 is possible.

[0125] Specifically, the notification control unit 151 of the fourth embodiment executes notification control such that, when power is supplied to the refrigerator 100 in a state in which communication between the first communication unit 103 and the server 400 is not permitted, the notification unit 50 performs notification so as to notify that communication with the server 400 is possible. When starting to supply power to the refrigerator 100, the user plugs the power supply terminal of the refrigerator 100 into an outlet. That is, the user is near the refrigerator 100. Therefore, when the user is near the refrigerator 100, the notification unit 50 can notify that communication with the server 400 is possible. As a result, the user can be efficiently notified that the refrigerator 100 has a function for communicating with the server 400. That is, when the user is near the refrigerator 100, the refrigerator 100 performs notification, so that the user can easily recognize that the refrigerator 100 is the one that can be connected to the server 400. Then, the user can be prompted to permit communication between the refrigerator 100 and the server 400.

[0126] Furthermore, in a state where communication between the first communication unit 103 and the server 400 is not permitted, the notification control unit 151 of the fourth embodiment executes notification control to control the notification unit 50 to notify that communication with the server 400 is possible, based on the detection result of the moving object detection unit 101. Therefore, when the user is near the refrigerator 100, the notification unit 50 can notify that communication with the server 400 is possible. As a result, the user can be efficiently notified that the refrigerator 100 has a function for communicating with the server 400. Then, the user can be prompted to allow communication between the refrigerator 100 and the server 400.

[0127] Furthermore, for example, notification control unit 151, which executes notification control, generates control information for controlling display unit 110 so that display unit 110 displays an image indicating that it can communicate with server 400. Then control unit 150 controls display unit 110 so that display unit 110 displays an image indicating that it can communicate with server 400. Therefore, when the user is near refrigerator 100, display unit 110 displays an image indicating that it can communicate with server 400. As a result, the user can be efficiently notified that refrigerator 100 has a function for communicating with server 400. In other words, when the user is near refrigerator 100, display unit 110 of refrigerator 100 displays an image, so that the user can easily recognize that refrigerator 100 is the device that can connect to server 400.

[0128] Furthermore, for example, notification control unit 151, which executes notification control, generates control information for controlling speaker 120 so that speaker 120 outputs a sound indicating that communication with server 400 is possible. Then, control unit 150 controls speaker 220 so that speaker 120 outputs a sound indicating that communication with server 400 is possible. Therefore, when the user is near refrigerator 100, speaker 120 outputs a sound indicating that communication with server 400 is possible. As a result, it is possible to efficiently notify the user that refrigerator 100 has a function for communicating with server 400. In other words, when the user is near refrigerator 100, speaker 120 of refrigerator 100 outputs a sound, so that the user can easily recognize that refrigerator 100 is the device that can connect to server 400.

[0129] When the mobile object detection unit 101 detects the user multiple times, the notification control unit 151 executes notification control. Multiple times indicates an integer equal to or greater than 2. Therefore, the notification unit 201 does not issue a notification every time the user is detected. As a result, it is possible to reduce power consumption required for notification control.

[0130] Furthermore, in the fourth embodiment, the notification control unit 151 executes notification control to control the notification unit 50 to notify that communication with the server 400 is possible, based on the detection result of the open / close detection unit 102, in a state in which communication between the first communication unit 103 and the server 400 is not permitted. Therefore, when at least one of the first door unit 11, the second door unit 21, and the third door unit 31 is opened by the user, the user is near the refrigerator 100. In other words, when the user is near the refrigerator 100, the notification unit 201 can notify that communication with the server 400 is possible. As a result, the user can be efficiently notified that the refrigerator 100 has a function to communicate with the server 400. Then, the user can be prompted to permit communication between the refrigerator 100 and the server 400.

[0131] When the open / close detection unit 102 detects multiple times that one of the openings of the first refrigerator compartment 10, the second refrigerator compartment 20, and the freezer compartment 30 has been opened, or that one of the openings of the first refrigerator compartment 10, the second refrigerator compartment 20, and the freezer compartment 30 has been closed, the notification control unit 151 executes notification control. Multiple times indicates an integer of 2 or more. Therefore, the notification unit 201 does not issue a notification every time a user is detected. As a result, the power consumption required for the notification control can be reduced.

[0132] The notification control unit 151 executes notification control when a predetermined time arrives. Therefore, for example, by setting the predetermined time to a time in the afternoon when the user is taking a break, the user can be efficiently notified that the refrigerator 100 has a function for communicating with the server 400. As a result, the user can be prompted to allow communication between the refrigerator 100 and the server 400.

[0133] When communication between the first communication unit 103 and the fifth communication unit 403 of the server 400 is permitted, the notification control unit 151 does not execute notification control. Therefore, it is possible to suppress unnecessary notifications to the user. As a result, it is possible to reduce power consumption required for unnecessary notification control.

[0134] The change unit 152 changes the content of the notification by the notification unit 201 based on the number of times the notification control has been executed.

[0135] The determination unit 153 determines whether or not the number of times the notification control is executed exceeds the threshold value. When the determination unit 153 determines that the number of times the notification control is executed exceeds the threshold value, the notification control unit 151 of the fourth embodiment does not execute the notification control. Therefore, it is possible to determine whether or not the user desires communication between the server 400 and the refrigerator 100. As a result, it is possible to prevent the user from feeling annoyed by unnecessary notifications.

[0136] Moreover, the control unit 150 of the fourth embodiment executes the process shown in Fig. 3. When the control unit 150 of the fourth embodiment executes the process shown in Fig. 3, step S14 is omitted, and the content of step S15 is changed.

[0137] Specifically, in step S15, the notification control unit 151 judges whether or not information indicating that communication between the refrigerator 100 and the server 400 is permitted has been acquired. If information indicating that communication is permitted has not been acquired (No in step S15), the process proceeds to step S17. If information indicating that communication is permitted has been acquired (Yes in step S15), the process proceeds to step S16.

[0138] Moreover, the control unit 150 of the fourth embodiment executes the process shown in Fig. 4. When the control unit 150 of the fourth embodiment executes the process shown in Fig. 4, step S109 is omitted. And the content of step S110 is changed. Step S110 with the changed content corresponds to step S15 executed by the control unit 150 of the fourth embodiment.
