A refrigerator compartment 202 is provided at the top of the heat insulating box 201. Below the refrigerator compartment 202, a freezer compartment 203 is provided, for example, via a partition wall filled with a heat insulating material. Below the freezer compartment 203, for example, a vegetable compartment 204 is provided via a partition wall filled with a heat insulating material. In addition, the positional relationship, size, number, etc. of the refrigerator compartment 202, the freezer compartment 203, and the vegetable compartment 204 are only examples, and are not limited to the above. In addition to the refrigerator compartment 202, the freezer compartment 203, and the vegetable compartment 204, other storage compartments for storing stored items at a predetermined temperature may be provided.

  The freezer compartment 203 is a space for storing stored items in a frozen state at a preset temperature. The refrigerator compartment 202 is a space for refrigerated storage of stored items at a higher temperature than the freezer compartment 203, and the vegetable compartment 204 is a space for maintaining stored items such as vegetables refrigerated while maintaining the temperature higher than that of the refrigerator compartment 202.

  For example, the refrigerator compartment 202 is opened and closed by a pair of doors 211 that are rotatably supported at the left and right ends of the refrigerator compartment 202. The freezer compartment 203 and the vegetable compartment 204 are opened and closed by drawer type doors 212 and 213 formed integrally with the storage case, for example.

  A cold air passage 205 and a cold air passage 206 connected via a damper 128 are provided on the back surfaces of the freezer compartment 203 and the refrigerator compartment 202. A cold room fan 207 and a cold room fan 208 for circulating cold air are arranged in the cold air passage 205 and the cold air flow path 206, respectively. Below the freezer compartment fan 207, an evaporator 209 that generates cold air is disposed. In addition, a defrosting unit 129 for removing (defrosting) frost attached to the evaporator 209 is provided below the evaporator 209. The defrosting part 129 is a heater, for example, and the upper surface of the defrosting part 129 is covered with a heater cover 210. The heater cover 210 suppresses failure, breakage, and the like of the defrosting unit 129 caused by the defrosting water dripping onto the defrosting unit 129.

  The cold air passage 205 is provided on the back surface of the freezer compartment 203. A part of the lower part of the cold air passage 205 is provided on the back of the vegetable compartment 204. The cool air passage 205 includes a discharge port 214 that is an opening for discharging cool air to the freezer compartment 203 and a return port 215 that is an opening for returning the cool air from the freezer chamber 203 to the cool air passage 205. The cool air flow path 206 is provided on the back surface of the refrigerating chamber 202 and includes a discharge port 216 that is an opening for discharging cool air. The heat insulating box 201 is provided with a passage (not shown) that connects the refrigerator compartment 202 and the vegetable compartment 204. The cold air passage 205 is provided with a return port 218 that opens into the vegetable compartment 204 and through which the cold air returns from the vegetable compartment 204 to the cold air passage 205.

  A machine room 217 is provided below the cold air passage 205 on the back of the vegetable room 204. A compressor 126 is installed in the machine room 217. By driving the compressor 126, the refrigerant flows through a refrigerant pipe (not shown) connected to the compressor 126. The evaporator 209 connected to the compressor 126 via the refrigerant pipe is cooled. The evaporator 209 has flat fins (not shown), and refrigerant pipes pass through the fins. And the said air is cooled by flowing air between several fins.

  When the freezer compartment fan 207 is driven, the cooled cold air flows through the cold air passage 205. The cold air flowing through the cold air passage 205 is discharged from the discharge port 214 into the freezer compartment 203. The cool air discharged from the discharge port 214 flows through the inside of the freezer compartment 203, cools the stored items inside the freezer compartment 203, and returns to the cool air passage 205 from the return port 215. That is, the cold air in the cold air passage 205 circulates in the freezer compartment 203, cools the internal storage (receives heat from the storage and is heated), and returns to the cold air passage 205.

  When the damper 128 is open, the cool air flowing through the cool air passage 205 flows into the cool air flow path 206. By driving the freezer compartment fan 207 and the freezer compartment fan 208 with the damper 128 open, the cold air circulating in the freezer compartment 203 and the cold air passage 206 is refrigerated from the discharge port 216 as described above. It is discharged into the chamber 202. Then, the cold air discharged from the discharge port 216 flows in the refrigerator compartment 202 to cool the stored items in the refrigerator compartment 202. The cold air flowing in the refrigerator compartment 202 flows into the vegetable compartment 204, flows inside the vegetable compartment 204, cools the stored items in the vegetable compartment 204, and returns to the cold passage 205 from the return port 218. .

  The cold air is heated to take heat away from the stored items when flowing in the refrigerator compartment 202. Then, since the heated cold air flows into the vegetable compartment 204, the vegetable compartment 204 becomes hotter than the refrigerator compartment 202.

  In addition, the structure of the said refrigerator 101 is an example, Comprising: The refrigerator 101 concerning this Embodiment is not necessarily limited above. For example, in the above description, the case where the refrigerator 101 has three storage chambers of the refrigerator compartment 202, the freezer compartment 203, and the vegetable compartment 204 has been described. However, the refrigerator 101 may be configured to have a different number of storage compartments, or the damper 128. The number of dampers 128 and fans 127 different from the above may also be provided for the fan 127 and the fan 127.

  FIG. 3 is a diagram illustrating an example of a functional configuration of the control unit of the home appliance illustrated in FIG. 1. As illustrated in FIG. 3, the control unit 111 of the home appliance 103 according to the present embodiment functionally includes a home appliance side state information acquisition unit 301 and a home appliance side device identification information acquisition unit 302.

  The home appliance-side state information acquisition unit 301 acquires, for example, state information indicating a state in which food after being cooked by the home appliance 103 is expected to be put into a predetermined storage room of the refrigerator 101. Here, the state information is set in advance, for example, for each home appliance 103 and for each cooking mode of the home appliance 103, corresponding to a situation where food after cooking is introduced. Specifically, for example, when the home appliance 103 is a microwave oven, the status information starts cooking in a preparation recipe or a cooking recipe that is a process of cooling in a refrigerator after heating in the microwave oven. It is represented by state information ST1 indicating a state (for example, a state in which the preparation mode is selected by the user and the start of cooking in the mode is selected). In addition, for example, when the home appliance 103 is a rice cooker, the state information is represented by state information ST2 that represents a state that rice cooking in the freezing rice course has started. In addition, the status information includes the state in which the menu is searched in the microwave oven equipped with other menu functions, the state in which the IH cooking heater is energized, the state in which the juicer is energized, the state in which the shaved ice device is energized, Nespresso (registered trademark) application is opened and the ice coffee menu is selected, etc., so that the identification information is set in advance.

  The home appliance side device identification information acquisition unit 302 acquires device identification information for identifying the home appliance 103. Specifically, for example, the device identification information is represented by A1, A2, and the like. For example, the microwave oven is identified by A1, and the rice cooker is identified by A2. Then, the acquired state information and device identification information are transmitted to the refrigerator 101 via the communication unit 123.

  FIG. 4 is a diagram illustrating an example of a functional configuration of the control unit of the refrigerator in the present embodiment. As illustrated in FIG. 4, the control unit 121 of the refrigerator 101 functionally includes, for example, a state information acquisition unit 401, a device identification information acquisition unit 402, a cooling control information acquisition unit 403, and a temperature control unit 404.

  The status information acquisition unit 401 acquires status information from the home appliance 103 via the network 102. Specifically, for example, when the home appliance 103 is a microwave oven, the identification information ST1 is acquired when cooking in the preparation mode is started.

  Device identification information acquisition section 402 acquires device identification information from home appliance 103. For example, in the case of the above example, the device identification information acquisition unit 402 acquires A1.

  The cooling control information acquisition unit 403 acquires cooling control information representing the content of the cooling control of the refrigerator 101 associated with the state information. Specifically, in the present embodiment, for example, the cooling control information will be described below as including changed temperature information that is changed from a set temperature set in advance by the user or the like from the cooling control information acquisition unit 403. The cooling control information acquisition unit 403 acquires the changed temperature information and the storage room identification information based on the state information, the device identification information, and the changed temperature related information. For example, as shown in FIG. 5, the cooling control information acquisition unit 403 acquires changed temperature related information in which state information, device identification information, changed temperature information, and storage room identification information are associated. The cooling control information acquisition unit 403 acquires changed temperature information associated with the acquired state information and device identification information based on the changed temperature related information. In the case of the above example, since the changed temperature information: -2 and the storage room identification information: C1 are associated with the status information: ST1 and the device identification information: A1, the cooling control information acquisition unit 403 changes the changed temperature information: -2. The storage room identification information: C1 is acquired. Here, the storage room identification information represents information for identifying each storage room. Specifically, for example, if the changed temperature information is −2, it represents that the temperature is lowered by 2 degrees from the set temperature, and for example, C1 represents a freezer compartment.

  The temperature controller 404 controls the temperature of the storage room based on the acquired cooling control information. Specifically, for example, the temperature control unit 404 controls the storage room identified by the storage room identification information to be changed from a preset temperature set based on the acquired changed temperature information. More specifically, for example, the temperature control unit 404 controls the fan 127, the damper 128, the compressor 126, and the like so as to change the temperature from a preset temperature. Since the temperature control of each storage chamber by the compressor 126 and the like is well known, a detailed description thereof will be omitted. In the case of the above example, when the set temperature of the storage room identified by the storage room identification information: C1 is preset at 6 ° C., the temperature control unit 404 has the changed temperature information of −2, so the storage room The temperature is controlled to 4 ° C.

  FIG. 6 is a diagram illustrating an example of the flow of the refrigerator in the present embodiment. As illustrated in FIG. 6, the state information acquisition unit 401 acquires state information from the home appliance 103 (S101). The identification information acquisition unit acquires device identification information from the home appliance 103. (S102). The cooling control information acquisition unit 403 acquires the changed temperature information and the storage room identification information based on the state information, the device identification information, and the changed temperature related information. (S103). Based on the acquired changed temperature information, the temperature control unit 404 controls the storage room identified by the storage room identification information to be changed from a preset set temperature. (S104). In addition, this Embodiment is not limited to the said flow, A various deformation | transformation is possible. For example, the order of S101 and S102 may be reversed.

  According to the present embodiment, for example, the refrigerator 101 that can further suppress the power consumption by performing the cooling control based on the user's action (for example, the user's operation) about the home appliance 103 other than the refrigerator 101. And the refrigerator system 100 can be provided. Specifically, for example, when a state in which food input is expected in a predetermined home appliance 103 is started, the temperature of the storage room corresponding to the end of cooking by the predetermined home appliance 103 is determined from a preset temperature. Can be changed. Thereby, compared with the case where this embodiment is not used, for example, when the food cooked in the home appliance 103 is put into the storage room of the refrigerator 101, the temperature of the storage room is set in advance. By keeping the temperature lower than the temperature, an increase in the temperature of the storage room after the food is added can be suppressed. Therefore, it is possible to suppress a rapid increase in the number of revolutions of the compressor 126 due to a rapid increase in the temperature in the storage chamber when the food after cooking is input, thereby suppressing power consumption.

  The present invention is not limited to the above-described embodiment, and is substantially the same configuration as the configuration shown in the above-described embodiment, a configuration that exhibits the same operational effects, or a configuration that can achieve the same purpose. May be replaced. For example, in the above description, the change temperature information corresponding to each state information and device identification information is acquired, and the case where the temperature of the storage room is changed based on the change temperature information has been described. Information representing the changed set temperature (precooling temperature) may be associated with each piece of information, and the temperature of the storage room may be changed based on the information representing the changed set temperature. Moreover, you may use in combination with 2nd Embodiment regarding the operation | movement of the defrosting part 129 mentioned later. Furthermore, an expected charging time information acquisition unit 701, which will be described later, may be provided so that the temperature of the corresponding storage room is made lower than a preset temperature by the expected charging time. Furthermore, in the above description, the case where the changed temperature information corresponding to the state information and the device identification information is associated is described as an example. However, the changed temperature information may be associated with the state information.

(Second Embodiment)

  Next, a second embodiment of the present invention will be described. In the following, description of points that are the same as those of the first embodiment will be omitted.

  FIG. 7 is a diagram for describing an example of a functional configuration of the control unit of the refrigerator in the present embodiment. As shown in FIG. 7, the control unit 121 of the refrigerator 101 in the present embodiment is functionally, for example, a state information acquisition unit 401, a device identification information acquisition unit 402, a cooling control information acquisition unit 403, and a temperature control unit 404. , An expected charging time information acquisition unit 701, a defrosting determination unit 702, a defrosting time calculation unit 703, a defrosting end determination unit 704, and a defrosting necessity determination unit 705 are included.

  Similarly to the first embodiment, the state information acquisition unit 401 acquires state information from the home appliance 103. For example, the state information acquisition unit 401 acquires the state information ST1. Device identification information acquisition section 402 acquires device identification information from home appliance 103. For example, the device identification information acquisition unit 402 acquires A1.

  The expected charging time information acquisition unit 701 acquires predicted charging time information indicating the charging time when food is expected to be charged into the refrigerator 101 based on the acquired state information and device identification information. Specifically, for example, the expected insertion time information acquisition unit 701 acquires the expected insertion time related information associated with the state information and the device identification information as shown in FIG. Here, the expected charging time related information is set based on statistical values or the like in advance for each cooking mode of each home appliance, for example, and represents the time (for example, 90 minutes) until the food is charged into the refrigerator 101. . The expected insertion time information acquisition unit 701 acquires the expected insertion time information based on the status information, the device identification information, and the expected insertion time related information. Specifically, for example, as shown in FIG. 8, since 90 is associated with the acquired ST1 and A1, 90 is acquired as the expected insertion time information. Then, the expected insertion time information acquisition unit 701 acquires the expected insertion time based on the current time and the expected insertion time information. Note that the expected insertion time may be configured to correspond to the time when cooking by the home appliance 103 is completed. Also, the current time is acquired from, for example, the time measuring unit 131 that measures time.

  The defrost determination part 702 determines whether the defrost part 129 is defrosting now. Specifically, for example, the defrost determination unit 702 is configured to determine whether the defrosting unit 129 is currently defrosted based on whether or not the defrosting unit 129 is energized.

  The defrosting time calculation unit 703 calculates the remaining defrosting time when it is determined that the defrosting determination unit 702 is currently defrosting. Specifically, the defrosting time calculation unit 703 acquires, for example, the time when the defrosting unit 129 starts defrosting, the current time, and the time required for defrosting, and the defrosting time required for defrosting and the current defrosting are acquired. The difference from the frost time (difference from the current time to the defrost start time) is obtained. Here, the defrosting time, which is a period required for defrosting, is grasped in advance by an experiment or the like for each refrigerator 101 and stored in the storage unit 122. For example, if the current time is 10:00, the time when the defrosting unit 129 starts defrosting is 9:15, and the time required for defrosting is 1 hour, the difference from the current time to the defrosting start time is 45 minutes. Therefore, the remaining defrosting time is calculated as 15 minutes. The time required for defrosting is set based on experiments and the like in advance.

  The defrosting end determination unit 704 determines whether or not the defrosting is completed by the expected charging time based on the calculated remaining defrosting time. Specifically, the defrosting end determination unit 704 obtains the defrosting end time based on the current time and the remaining defrosting time, and when the defrosting end time is earlier than the expected charging time, the expected charging time It is determined that the defrosting is finished by When it is determined that the defrosting is completed by the expected charging time, the defrosting unit 129 continues the defrosting. For example, in the case of the above example, if the expected charging time is 11:00 and the current time is 10:00, the defrosting ends at 10:15 when the remaining defrosting time of 15 minutes elapses. Determines that the defrosting is completed by the expected charging time, and the defrosting unit 129 continues the defrosting.

  On the other hand, when the defrosting end determination unit 704 determines that the defrosting does not end by the expected charging time, the defrosting end determination unit 704 causes the defrosting unit 129 to interrupt the defrosting operation by the expected charging time. Instruct. Then, after the elapse of a predetermined period (for example, 5 hours after the end of cooking or the expected charging time), the defrosting unit 129 is instructed to start defrosting. Thereby, the further temperature rise by operating the defrosting part 129 can be prevented, for example at the time of throwing into the refrigerator 101 after cooking. The predetermined period is set in advance by a statistical value or the like.

  If the defrosting necessity determination unit 705 determines that the defrosting unit 129 is not currently defrosting, the defrosting necessity determination unit 705 determines whether or not defrosting is necessary by the expected charging time. Here, the defrosting unit 129 is designed to start defrosting at a preset timing. Specifically, for example, the timer 131 is caused to measure the time when the compressor 126 has been operated since the last defrosting, and the defrosting is performed when the sum of the times (integrated time) reaches a predetermined time. Designed to be Note that the defrosting start timing of the defrosting unit 129 is not limited to the above. For example, as disclosed in Patent Document 1, in addition to the time when the compressor 126 is operated, the number of times the door of the refrigerator 101 is opened and closed, and the like. It may be designed to start the defrosting operation based on the above. The defrosting necessity determining unit 705 determines that defrosting is necessary when it is determined that the accumulated time reaches a predetermined time before the expected charging time, and removes when it is determined that the defrosting is not reached. It is determined that frost is unnecessary.

  When the defrost necessity determination unit 705 determines that defrosting is necessary by the expected insertion time, the defrost time calculation unit 703 acquires the defrost time, and the defrost end determination unit 704 It is determined whether or not the defrosting is completed at the expected charging time. For example, as described above, the defrosting time is obtained from a statistical value or the like, and therefore the defrosting time (for example, 10 o'clock) from the timing at which the defrosting unit 129 starts defrosting at a preset timing (for example, 10 o'clock). 1 hour) (11 o'clock) before the expected charging time (for example, 12:00), it is determined that the defrosting is completed at the predicted charging time. In this case, the defrosting unit 129 starts defrosting at a preset timing. In this case, the defrosting necessity determining unit 705 may be configured to start defrosting at a timing when it is determined that defrosting is necessary. And the defrosting part 129 complete | finishes a process after completion | finish of a defrost.

  On the other hand, when the defrost necessity determination unit 705 determines that defrosting is necessary by the expected charging time, the defrosting termination determination unit 704 determines that defrosting does not end at the expected charging time. In this case, the defrosting unit 129 instructs to defer the start of defrosting and start the defrosting after a predetermined period has elapsed (for example, 5 hours after the expected charging time). And the defrosting part 129 complete | finishes a process after completion | finish of a defrost.

  FIG. 9 is a diagram illustrating an example of a flow of the refrigerator 101 in the present embodiment. As shown in FIG. 9, as in the first embodiment, the state information acquisition unit 401 acquires state information from the home appliance 103 (S201). The device identification information acquisition unit 402 acquires device identification information from the home appliance 103 (S202). The expected charging time information acquisition unit 701 acquires predicted charging time information representing the expected charging time based on the state information and the device identification information (S203).

  The defrost determination part 702 determines whether the defrost part 129 is defrosting now (S204). When the defrost determination part 702 determines with defrosting now, the defrost time calculation part 703 calculates the remaining defrost time (S205). The defrosting end determination unit 704 determines whether or not the defrosting is completed by the expected charging time based on the calculated remaining defrosting time (S206). When it is determined that the defrosting is completed by the expected charging time, the defrosting unit 129 continues the defrosting (S207). And a process will be complete | finished when a defrost is complete | finished.

  On the other hand, when it is determined in S206 that the defrosting is not completed by the expected charging time, the defrosting means interrupts the defrosting by the predicted charging time (S208). The defrosting unit 129 starts defrosting after a predetermined time has elapsed from the end of the expected charging time (S209). And a process will be complete | finished when a defrost is complete | finished.

  If the defrost determination unit 702 determines in S204 that the defrosting is not currently performed, the defrost necessity determination unit 705 determines whether or not the defrost is necessary by the expected charging time (S210). . When the defrost necessity determination unit 705 determines that defrosting is necessary by the expected charging time, the defrost time calculation unit 703 calculates the defrost time (S211). The defrosting end determination unit 704 determines whether or not the defrosting is completed by the expected charging time based on the calculated defrosting time (S212). If the defrosting end determination unit 704 determines in S212 that the defrosting is to be completed by the expected charging time, it starts defrosting at a preset time (S213). And a process will be complete | finished when a defrost is complete | finished. In S212, when the defrosting end determination unit 704 determines that the defrosting is not completed by the expected charging time, the defrosting unit 129 starts the defrosting after a predetermined time has elapsed from the predicted charging time (S214). . And a process will be complete | finished when a defrost is complete | finished. If the defrosting necessity determining unit 705 determines in step S210 that defrosting is not necessary by the expected charging time, the process proceeds to step S213. In addition, this Embodiment is not limited to the said flow, A various deformation | transformation is possible. For example, the order of S201 and S202 may be reversed. Further, for example, when the defrosting end determination unit 704 determines in S212 that the defrosting is not completed by the expected charging time, and the time when the defrosting time has elapsed from the current time is earlier than the predicted charging time. May be configured such that the defrosting is started before the preset time for starting the defrosting and the defrosting is completed by the expected charging time.

  According to the present embodiment, similarly to the first embodiment, for example, the power consumption can be further suppressed by performing the cooling control based on the user's action on the home appliance 103 other than the refrigerator 101. A refrigerator 101 and a refrigerator system 100 can be provided.

  Furthermore, according to the present embodiment, for example, when it is determined that the defrosting is not completed by the expected charging time, the defrosting unit 129 does not perform the defrosting operation at the predicted charging time, and the defrosting operation is performed after a predetermined period. Since frost is started, it is possible to prevent the defrosting unit 129 from performing a defrosting operation at the expected charging time. Thereby, the temperature rise based on the defrosting operation at the expected charging time can be suppressed by the defrosting operation.

  The present invention is not limited to the above-described embodiment, and is substantially the same configuration as the configuration shown in the above-described embodiment, a configuration that exhibits the same operational effects, or a configuration that can achieve the same purpose. May be replaced.

  Specifically, for example, the following modifications may be configured. FIG. 10 is a diagram for describing a functional configuration of the control unit 121 in a modification of the second embodiment. As shown in FIG. 10, this modification further includes a warning information acquisition unit 706 and a warning unit 707, for example.

  The warning information acquisition unit 706 acquires warning related information in which device identification information, state information, and warning information are associated with each other. For example, as shown in FIG. 11, the warning related information is associated with status information and warning information. Then, the warning information acquisition unit 706 acquires warning information associated with the state information and the warning information based on the acquired state information and warning information.

  Here, the warning information is, for example, identification information (for example, W1) for displaying warning information on the display unit 125 so as not to immediately put the finished dish into the refrigerator 101, or identification information (for example, for indicating by voice) For example, W2) and information (for example, W3) for displaying to the user that the cooked food is placed near the cold air return port are included.

  Based on the warning information, the warning unit 707 causes the display unit 125 to display or the playback unit 132 to reproduce sound. In this case, an increase in the temperature of the refrigerator 101 due to the input of food can be suppressed by the user following the warning. More specifically, for example, in the case of displaying to the user that the air is placed in the vicinity of the cool air return port 215, if the cool air return port 215, the influence of the air heated by the food in the storage chamber Therefore, an increase in the temperature of the storage chamber due to the input of food can be suppressed. In the above, position information in the vicinity of the cool air return port 215 may be stored in advance, and a space in the vicinity of the cool air return port 215 may be displayed on the display unit 125.

  The warning information is, for example, information for allowing the user to input whether or not the quick freezing space such as the switching room is to be used, and if the quick freezing space is used, indicates whether or not there is an empty space. You may comprise so that the information for showing with an audio | voice etc. may be included. For example, the warning information is also identified and stored by the identification information. The warning unit 707 causes the display unit 125 and the reproduction unit 132 to display or reproduce the information. In this case, the cooling efficiency of the refrigerator 101 can be improved by prompting the user to use the quick freezing space and using the quick freezing space.

  In addition, the said modification is not limited above, for example, combining with 1st Embodiment etc. besides the combination with the said 2nd Embodiment.

(Third embodiment)

  Next, a third embodiment of the present invention will be described. In the following, description of points that are the same as those in the first and second embodiments will be omitted.

  FIG. 12 is a diagram illustrating an example of a functional configuration of the control unit in the present embodiment. As shown in FIG. 12, the control unit 121 of the refrigerator 101 in the present embodiment includes, for example, an evaluation value information acquisition unit 801, an integrated score acquisition unit 802, an evaluation value determination unit 803, and a temperature control unit 404. The evaluation value information acquisition unit 801, the integrated score acquisition unit 802, and the evaluation value determination unit 803 correspond to the cooling control means in the claims.

  The evaluation value information acquisition unit 801 acquires an evaluation value based on state information, device identification information, and evaluation value related information. In the evaluation value related information, for example, status information, device identification information, and an evaluation value are associated as shown in FIG. Here, in FIG. 13, A1 represents a microwave oven and A2 represents a rice cooker. ST4 indicates that the setting mode setting screen has been opened for one minute or more, and ST1 indicates that cooking is started in the setting mode. Moreover, ST5 shows the state which the cooking of the rice course for freezing started. Then, 2, 5 and the like are associated with each state information and device identification information as evaluation values in order from the upper row of FIG. For example, when A1 is acquired by the state information acquisition unit 401 and ST4 is acquired by the device identification information acquisition unit 402, the evaluation value information acquisition unit 801 acquires evaluation value information because the evaluation value 2 is associated with A1 and ST4. The unit 801 acquires the evaluation value 2.

The integrated score acquisition unit 802 sequentially obtains the integrated score of the evaluation values acquired by the evaluation value information acquisition unit 801 sequentially. Specifically, for example, the integrated score acquisition unit 802 obtains an integrated score of evaluation values every time an evaluation value is acquired. That is, for example, when 2 is acquired as the evaluation value by the evaluation value information acquisition unit 801 and then 5 is acquired, the integrated score acquisition unit 802 acquires 7 as the integrated score. Here, the integrated score may be, for example, the sum of the evaluation values sequentially acquired by the evaluation value information acquisition unit 801, or a smooth moving average represented by the following formula 1.

  The evaluation value determination unit 803 determines whether the integrated score obtained by the integrated score acquisition unit 802 has exceeded a predetermined threshold. For example, when the integrated score is the sum of the evaluation values and the threshold is set to 3, and when the integrated score 7 is acquired, it is determined that the predetermined threshold is exceeded.

  When the evaluation value determination unit 803 determines that the integrated score exceeds a predetermined threshold, the temperature control unit 404 performs preset temperature control (pre-cooling control). The temperature control is, for example, temperature control for each storage room.

  Here, the temperature control includes, for example, temperature control for lowering the temperature of the freezer compartment 203 from a preset temperature (for example, setting from the user set temperature to −21 ° C.). The freezer compartment 203 cannot be cooled in a short time, and a large amount of electric power is required to cool it to the set temperature after the temperature of the freezer compartment 203 has risen due to the input of food. Therefore, by cooling the freezer compartment 203 in advance before the expected charging time, it is possible to suppress power consumption compared to the case of cooling after charging. In particular, in the present embodiment, since the pre-cooling control is performed based on the integrated score of the evaluation values acquired from the home appliance 103, the temperature is slowly lowered (pre-cooled) before the expected charging time when the user loads the food. Therefore, it is possible to suppress power consumption required for pre-cooling.

  In this case, the refrigerating room 202 may also be configured to start pre-cooling (for example, set to 1 ° C. from the user set temperature). In the case of a refrigerator room, in order to prevent freezing, the precooling control time may be measured and precooled only for a predetermined period (for example, 2 hours).

  FIG. 14 is a diagram illustrating an example of a flow of the refrigerator in the present embodiment. As illustrated in FIG. 14, the state information acquisition unit 401 acquires state information from the home appliance 103 (S301). The device identification information acquisition unit 402 acquires device identification information from the home appliance 103 (S302). The evaluation value information acquisition unit 801 acquires an evaluation value based on the state information, the device identification information, and the evaluation value related information (S303). The integrated score acquisition unit 802 obtains an integrated score of the evaluation values acquired by the evaluation value information acquisition unit 801 (S304). The evaluation value determination unit 803 determines whether or not the integrated score obtained by the integrated score acquisition unit 802 has exceeded a predetermined threshold (S305). When the evaluation value determination unit 803 determines that the integrated score has exceeded a predetermined threshold, the temperature control unit 404 performs preset temperature control (pre-cooling control) (S306). On the other hand, if it is determined that the integrated score does not exceed the predetermined threshold, the process returns to S301. In addition, this Embodiment is not limited to the said flow, A various deformation | transformation is possible. For example, the order of S301 and S302 may be reversed.

  According to the present embodiment, similarly to the other embodiments, for example, the refrigerator 101 that can further suppress power consumption by performing cooling control based on the user's action on the home appliance 103 other than the refrigerator 101. And the refrigerator system 100 can be provided. In addition, according to the present embodiment, it is possible to perform more precise cooling control by associating the evaluation value with the user's action on the household electrical appliances 103 other than the refrigerator 101, and further suppress power consumption. It can be planned.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, in the above description, the case where the pre-cooling control is performed when it is determined that the integrated score exceeds a predetermined threshold has been described. However, as in the first embodiment, it is determined that the integrated score exceeds the predetermined threshold. In such a case, it is possible to obtain the changed temperature information (S103) and perform temperature control based on the changed temperature information (S104).

  Moreover, you may comprise like the various modifications demonstrated below. In the first modification, the temperature control unit 404 presets the temperature of the refrigerator compartment 202 before the expected charging time when the evaluation value determination unit 803 determines that the integrated score exceeds a predetermined threshold. Control to lower than temperature. That is, precooling control of the refrigerator compartment 202 is performed. In this case, the temperature control unit 404 stops the cooling of the refrigerator compartment 202 when detecting that the food is put into the freezer compartment 203. Thereby, even if the cooling of the refrigerator compartment 202 is stopped for a predetermined period from the time when the food is added, the temperature of the refrigerator compartment 202 can be kept at a predetermined low temperature, and the freezer compartment 203 can be preferentially cooled. Note that detection of food being put into the freezer compartment 203 is performed by, for example, a door opening / closing sensor 130 that detects opening / closing of the door of the freezer compartment 203.

  In the second modification, the temperature control unit 404 is a case where the evaluation value determination unit 803 determines that the integrated score has exceeded a predetermined threshold, and when it is predicted that cooking will take a predetermined time or more, Only the freezer compartment 203 is configured to be controlled to a temperature lower than the set temperature by a predetermined time before the end of cooking. Thereby, the temperature rise of the freezer compartment 203 at the time of food addition can be suppressed, and power consumption can be reduced. In addition, when it is predicted that cooking takes a predetermined time (for example, 3 hours) or more, the temperature control unit 404 sets the temperature so that the temperature is lower than the set temperature from a predetermined time (for example, 3 hours) before the end of cooking. You may comprise so that it may control. Thereby, power consumption can be reduced compared with the case where temperature control of the freezer compartment 203 or the like is performed at a temperature lower than the set temperature immediately after determining that the integrated score exceeds a predetermined threshold. In this case, freezing of the refrigerator compartment 202 can be prevented. Note that the time expected to be cooked is obtained, for example, in advance by statistical values, stored in association with the state information and device identification information, and acquired based on the state information and device identification information.

  In the third modification, the defrosting unit 129 is configured to start defrosting when the evaluation value determination unit 803 determines that the integrated score exceeds a predetermined threshold. Thereby, it can suppress that the defrosting operation | movement of the defrosting part 129 is performed at the time of food addition.

  In the fourth modified example, when the evaluation value determination unit 803 determines that the integrated score exceeds a predetermined threshold, the flow of the defrosting process of S204 to S214 is performed as in the second embodiment. Configure as follows. Moreover, you may comprise so that the flow of the defrost process of S204 thru | or S214 may be performed like the said 2nd Embodiment at the timing estimated that cooking is started. Here, the cooking start timing is estimated, for example, the cooking start timing is stored in association with each piece of device identification information and state information, and the cooking start timing is estimated based on the device identification information and state information. Configure as follows.

  In the fifth modification, the evaluation value determination unit 803 determines whether or not the first threshold and the second threshold are exceeded, and when it is determined that the first threshold is exceeded, the fourth modification is performed. Similarly to the example, when the flow of the defrosting process of S204 to S214 is performed and then it is determined that the second threshold value is exceeded, the pre-cooling control of the second modified example is performed.

  The present invention is not limited to the above embodiments and modifications, and the above embodiments and modifications may be used in combination as long as they do not contradict each other. Further, in each of the above embodiments and each modified example, in order to prevent freezing, a predetermined time limit (for example, a maximum of 2 hours) is provided for pre-cooling control of a storage room such as the refrigerator compartment 202 where freezing is not preferable. May be. Furthermore, in each modification, although the precooling control of the freezer compartment 203 and the refrigerator compartment 202 was demonstrated, you may apply also to other storage rooms, such as the vegetable compartment 204. FIG.

(Fourth embodiment)

  Next, a fourth embodiment of the present invention will be described. In the following, description of points that are the same as those in the first to third embodiments will be omitted. FIG. 15 is a diagram illustrating an example of a functional configuration of the control unit 121 according to the fourth embodiment. As shown in FIG. 15, the control unit 121 in the fourth embodiment functionally includes a cooling control information acquisition unit 902.

  Similarly to the first embodiment, the state information acquisition unit 401 acquires state information from the home appliance 103. In addition, the device identification information acquisition unit 402 acquires device identification information from the home appliance 103.

  The cooling control information acquisition unit 902 acquires cooling control information (referred to as corresponding operation information in the present embodiment) representing the operation of the fan 127, the damper 128, the compressor 126, and the like based on the acquired state information and device identification information. To do. Specifically, for example, as illustrated in FIG. 16, the cooling control information acquisition unit 902 acquires corresponding operation related information in which state information, device identification information, and corresponding operation information are associated. Then, the cooling control information acquisition unit 902 acquires corresponding operation information representing the operation of the temperature control unit 404 based on the acquired state information and device identification information. Here, as the corresponding operation-related information, for example, as shown in FIG. 16, for example, the state information is ST2 indicating that rice cooking has started, and the device identification information is A2 indicating rice cooker. Corresponding operation information D1 for identifying such a corresponding operation is acquired. For example, according to the corresponding operation information, the timing unit 131 counts a predetermined period (for example, 5 minutes) after the state information is acquired by the state information acquisition unit 401, and the fan control unit 903, which will be described later, controls the fan 127 during the period. At the same time, the damper control unit 904, which will be described later, closes the damper 128 and stops discharging cool air into the storage chamber. When the timer 131 measures the predetermined period (for example, 5 minutes), the timer 131 then counts the predetermined period (30 minutes), and the damper control unit 904 operates the damper. The fan control unit 903 reduces the amount of cool air discharged into the storage chamber by setting 128 to be half open or by lowering the rotational speed of the fan 127 below a preset rotational speed. In the present embodiment, the state information represents a state in which the door of the refrigerator 101 is predicted to be opened. For example, state information in which preparation of a meal is predicted to start in the kitchen (other than the above) Or when the thawing of the frozen food is completed in the microwave oven).

  The temperature control unit 404 includes a fan control unit 903, a damper control unit 904, and a compressor control unit 905. The fan control unit 903 controls the operation of the fan 127. The damper control unit 904 controls the opening / closing of the damper 128. The compressor control unit 905 controls the rotational speed of the compressor 126 and the like. Then, the temperature control unit 404 controls the operations of the fan 127, the damper 128, and the compressor 126 according to the acquired corresponding operation information. Specifically, for example, when D1 is acquired as the corresponding operation information, a predetermined period (for example, 5 minutes) is measured after the state information is acquired by the time measuring unit 131 according to the corresponding operation information. The fan control unit 903 stops the fan 127 and the damper control unit 904 closes the damper 128 to stop the discharge of cold air to the storage chamber. When the timer 131 measures the predetermined period (for example, 5 minutes), the timer 131 further counts the predetermined period (30 minutes), and the damper controller 904 opens the damper 128 halfway during the predetermined period. Alternatively, the fan control unit 903 reduces the amount of cool air discharged into the storage chamber by, for example, lowering the rotational speed of the fan 127 below a preset rotational speed.

  Next, a processing flow in the present embodiment will be described. FIG. 17 is a diagram for explaining the flow of processing in the present embodiment.

  As shown in FIG. 17, the state information acquisition unit 401 acquires state information from the home appliance 103 (S401). In addition, the device identification information acquisition unit 402 acquires device identification information from the home appliance 103 (S402). The cooling control information acquisition unit 902 acquires corresponding operation information representing operations of the fan 127, the damper 128, the compressor 126, and the like based on the acquired state information and device identification information (S403).

  The temperature control unit 404 controls the fan 127 and the like according to the corresponding operation information acquired in S403 (S404). Then, the process ends.

  The present invention is not limited to the above flow, and various modifications are possible. For example, in the above, the order of S401 and S402 may be reversed.

  According to the present embodiment, for example, as in other embodiments, a refrigerator that can further suppress power consumption by performing cooling control based on the user's behavior with respect to the home appliances 103 other than the refrigerator 101. 101 and the refrigerator system 100 can be provided. Furthermore, according to the present embodiment, it may be possible to further suppress the outflow amount of cold air from the corresponding storage chamber when the door is opened. Specifically, for example, in a situation where a door is expected to be opened, by controlling the operation of a refrigerator fan or the like based on the corresponding operation information, the amount of cold air flowing out from the storage room corresponding to the door Can be suppressed.

  The present invention is not limited to the above embodiment, and various modifications can be made. For example, it can be replaced with a configuration that is substantially the same as the configuration described in the above embodiment, a configuration that exhibits the same operational effects, or a configuration that can achieve the same purpose. For example, a door opening information acquisition unit that acquires door opening information indicating that the door has been opened from the door opening / closing sensor 130 is provided, and when door opening information is acquired, a fan for a refrigerator, etc., according to the corresponding operation information May be configured to operate. Thereby, the outflow amount of the cold air from the corresponding storage chamber when the door is opened can be suppressed.

  For example, this embodiment may be used in combination with the first to third embodiments and each of the modified examples as long as they do not contradict each other. Further, for example, the state information based on the user's action may be configured to be shared with other users together with the position information.
