Description

  The present invention relates to a refrigerator capable of obtaining an energy saving effect while maintaining the preservation quality of food stored in a storage room, and a network system including the refrigerator.

  Due to the recent increase in energy conservation, various home appliances have various power saving functions. Typical examples of the air conditioner include a power ON / OFF control function based on the presence / absence detection of a person, a save mode for limiting driving ability at night when there is little movement of the person, and the like.

  However, a refrigerator that manages food stored in the storage room requires continuous cooling operation regardless of the presence or absence of people or day and night. It varies greatly depending on the usage situation of the user. Therefore, even when power saving operation is performed, it is necessary to form a cooling environment that is not excessive or deficient in correspondence with the storage load status and the user usage status while maintaining the storage quality of food.

  Therefore, as a conventional refrigerator that controls the cooling capacity according to the amount of food stored in the storage room, a temperature sensor that detects the temperature in the storage room and a weight sensor that detects the weight of food in the storage room are installed. Based on the detection result by the temperature sensor and the detection result by the weight sensor, the one that prevents excessive cooling or insufficient cooling by controlling the rotation speed of the compressor or the temperature of the food in the storage chamber has been proposed. (For example, refer to Patent Document 1).

  In addition, as a conventional refrigerator that automatically controls the refrigeration and freezing environment based on regional characteristics, for example, when downloading an application suitable for the area where the refrigerator is installed from the network and storing regional food, A device capable of forming an optimum environment has been proposed (see, for example, Patent Document 2).

JP 2013-011383 A (refer to, for example, [0019] to [0027] and FIGS. 3 to 7) Japanese Patent No. 3636441 (see, for example, [0007] to [0014], FIG. 2 and FIG. 3)

  In the refrigerator described in Patent Document 1, even if the temperature in the storage chamber is high, cooling is suppressed when the weight of the food is light, so that excessive cooling and freezing can be prevented. Further, even if the temperature in the storage chamber is low, the cooling is continued when the weight of the food is heavy. Therefore, even when the food is packed in the storage chamber, local cooling shortage can be avoided.

  However, since the type of food and the usage status of the user are not reflected, there is a situation in which fresh food that should be stored at a lower temperature and vegetables with low-temperature damage are stored at the same temperature, resulting in quality deterioration. There was a problem of doing it. In addition, there is a problem that power consumption is unnecessarily increased by cooling more than necessary for long-term absence.

  Moreover, in the refrigerator described in Patent Document 2, an application suitable for the region where the refrigerator is installed is downloaded, and a temperature environment corresponding to the region-specific food is selected. However, the load amount of food and the use situation of the user are not reflected, and the cooling operation is performed in a specific pattern for each region. For this reason, there is a problem that quality degradation occurs or power consumption increases unnecessarily.

  The present invention has been made to solve the above-described problems, and an object of the present invention is to provide a refrigerator capable of obtaining an energy saving effect while maintaining the storage quality of food and a network system including the refrigerator. It is said.

The refrigerator according to the present invention includes a main body constituting an outer shell, a plurality of storage rooms provided in the main body, food storage information in the storage room, or recommended setting of the storage room based on user schedule information A recommended set temperature calculating means for calculating a temperature; a recommended set temperature approval correcting means for prompting a user to approve or correct the recommended set temperature calculated by the recommended set temperature calculating means; and the recommended set temperature approval correcting means. A set temperature determining means for determining the recommended set temperature approved or corrected by the user as the set temperature of the storage room, a schedule setting means for inputting user schedule information, and the user schedule input by the schedule setting means Schedule management means for receiving and organizing information, and the recommended set temperature calculation means is And calculates the recommended set temperature on the basis of the schedule information organized the user in the schedule management unit.

  According to the refrigerator of the present invention, the recommended set temperature is calculated based on the food storage information or the user's schedule information, that is, the use state of the user, and after the user approves or corrects, the set temperature is determined and the cooling control is performed. Therefore, it is possible to carry out a cooling operation without excess or deficiency, and to obtain an energy saving effect while maintaining the preservation quality of foods required by individual users.

FIG. 5 is an example showing a stored food confirmation screen (screen for erasing used food) displayed on the stored food input / display device 2 of the refrigerator 1000 according to Embodiment 1 of the present invention.
When the food stored in the storage room is used, the user erases the information on the food taken out of the storage room for use by the stored food input / display device 2 in the operation panel 1. FIG. 5 shows, as an example, a screen in the stored food input / display device 2 when 200 g of spinach expired in the example of FIG. 4 is used in the vegetable room 500.

  As an erasing method on this screen, first select the storage room taken out for use of food from the left side of the refrigerator 1000 (displayed with shading), and then specify the food taken out from the stored food list. (Displayed with shading), select the amount and unit that were taken out from the drop-down list displayed below. Finally, the procedure is to press the “use” button.

Next, an example of operation | movement of the refrigerator 1000 which concerns on this Embodiment 1 is demonstrated using FIGS.
As shown in FIG. 2, the air in the storage room cooled by the cooler 1002 is transferred to each storage room via the cooling air passage 1010 by the air transfer device 1003. Then, the return air after cooling each storage chamber is a circulating air path that returns to the cooler 1002 again via the return air path 1020. At this time, air (for example, −30 ° C. to −25 ° C.) cooled by the cooler 1002 is distributed to cool each storage chamber, and cooling air flows in by opening and closing a plurality of dampers including the refrigerator compartment damper 102. By adjusting the amount, the temperature is set individually for each storage room.

  For example, the damper of the freezer compartment 400 (for example, −22 ° C. to −16 ° C.) that is set to the lowest temperature is almost fully opened, and the damper of the vegetable room 500 (for example, 3 ° C. to 9 ° C.) that is set to the highest temperature is substantially fully closed. Yes. And the vegetable room 500 is indirectly cooled with the return air which cooled the refrigerator compartment 100 (for example, 0 degreeC-6 degreeC) and the chilled room 110 (for example, 0 degreeC-2 degreeC) lower than the vegetable room 500, etc., The set temperature has been changed.

  Here, the set temperature of each storage room can be adjusted to about ± 2 to 3 ° C. in response to overcooling or undercooling. For example, the freezer room 400 has a temperature of about −25 ° C. to −13 ° C. 100 can change the set temperature in the range of about −2 ° C. to 9 ° C.

  In addition, when a specific storage room is set to a low temperature due to insufficient cooling, for example, when only the refrigerating room 100 is lowered, the cooling air to the refrigerating room 100 is increased by increasing the opening degree of the refrigerating room damper 102. Increase the inflow volume. However, when it is necessary to lower the temperature of the plurality of storage chambers, the number of rotations of the compressor 1001 and the amount of air transported by the air transport device 1003 are increased, and the cooling capacity of the refrigeration cycle is increased. Therefore, the power consumption of the refrigerator 1000 increases.

  On the contrary, when a specific storage room is set to a high temperature due to excessive cooling, for example, when only the refrigerator compartment 100 is heated, the cooling of the refrigerator compartment 100 is reduced by reducing the opening degree of the refrigerator compartment damper 102. Reduce air inflow. However, when it is necessary to increase the temperature of the plurality of storage chambers, the number of rotations of the compressor 1001 and the amount of air transported by the air transport device 1003 are decreased, and the cooling capacity of the refrigeration cycle is decreased. Therefore, the power consumption of the refrigerator 1000 decreases.

  The power consumption of the refrigerator 1000 is small compared to other home appliances such as room air conditioners and IH cooking heaters, but since the food is managed, the power cannot be turned off (cooling stopped) like those home appliances. Therefore, in order to implement a power saving operation that consumes less power than a normal operation, it is necessary to raise the set temperature of each storage room according to information about the food storage status or information about the user usage status. For example, when the amount of food stored in the storage room is small, or when storing food that does not require a low-temperature environment as high as the normal set temperature, even if the set temperature is raised, power-saving operation is performed without impairing the storage quality of the food. It becomes possible to do.

  Therefore, in the first embodiment, as shown in FIG. 2, the stored food information input by the stored food input / display device 2 in the operation panel 1 is organized by the stored food management means 3 and stored. Based on the food information, the recommended set temperature calculation means 4 calculates the recommended set temperature. Then, the calculated recommended set temperature is approved or corrected by the user in the recommended set temperature display / correction device 5 in the operation panel 1.

  Thereafter, the set temperature is determined by the set temperature determining means 6. Then, based on the determined set temperature, a control change instruction is sent to the cooling control means 7 that controls the compressor 1001, the air conveyance device 1003, the refrigerator compartment damper 102, and other storage compartment dampers. The cooling control means 7 to which the control change instruction is sent controls the compressor 1001, the air conveyance device 1003, the refrigerator compartment damper 102 and other storage room dampers, and changes the cooling capacity for each storage room. The set temperature of each storage room can be changed.

  Specifically, on the stored food setting screen of the stored food input / display device 2 in the operation panel 1 shown in FIG. 3, for each food actually stored in the refrigerator 1000, the type, amount, unit, And enter the storage period. The inputted stored food information is organized for each storage room in the stored food management means 3 as in the stored food list shown in FIG. The recommended set temperature is calculated by the recommended set temperature calculation means 4 based on the type and amount of the food stored in each storage room and the remaining time for the storage deadline (planned) date, and the recommended setting in the operation panel 1 is calculated. It is displayed on the temperature display / correction device 5.

  FIG. 6 is an example showing a set temperature confirmation screen displayed on the recommended set temperature display / correction device 5 of the refrigerator 1000 according to Embodiment 1 of the present invention. FIG. 6 shows the recommended set temperature of each storage room calculated by the recommended set temperature calculating means 4.

  In the example of FIG. 6, it is displayed on the screen that it is recommended to change the set temperature for each of the refrigerating room 100, the switching room 300, and the freezing room 400 (respectively indicated by shading). The refrigerator compartment 100 is recommended to be heated from 3 ° C. to 10 ° C. (the refrigeration upper limit temperature) because there are many beverages and freshly prepared dishes and the overall storage capacity is small. Since the switching room 300 contains only meat and fish to be used within 3 days, it is recommended to raise the temperature from −7 ° C. to 0 ° C. (chilled temperature). In the freezer compartment 400, there is no ice that melts unless it is -18 ° C or lower, and the stored frozen food and meat are scheduled to be used within one month. : ** = two-star) is recommended. When these recommended set temperatures are adopted, it is displayed on the screen that an energy saving effect of about 25% can be obtained with respect to the current situation.

  At this time, when these recommended set temperatures are adopted, they are determined by pressing the “Yes” button at the lower right of the screen. When not adopted, the respective set temperatures are corrected after the “No” button is pushed. Is possible. For example, although not shown, if only the switching room 300 is changed to a setting that maintains the current −7 ° C., the energy saving rate corresponding to that is calculated and displayed, and is confirmed again by pressing the “Yes” button.

  As described above, in the recommended set temperature display / correction device 5, the set temperature information approved or corrected by the user is transmitted to the set temperature determining means 6 and determined, and the control change instruction based on the set temperature is the cooling control. It is transmitted to the means 7.

  The cooling control means 7 transmits a control signal for achieving the set temperature to the compressor 1001, the air conveyance device 1003, the refrigerator compartment damper 102, and other dampers (not shown). For example, in order to raise the temperature of the freezer compartment 400, a signal for reducing the frequency of the motor is transmitted to the compressor 1001 and the air conveyance device 1003, and in order to raise the temperature of the refrigerator compartment 100, the refrigerator compartment damper 102 is closed. Send a signal.

  For example, when the recommended set temperature in which all the storage rooms are refrigerated temperature zones, such as when storing beverages in the freezer compartment 400 and cut vegetables in the switching chamber 300, the necessary storage quality is obtained. It is possible to obtain a significant energy saving effect of about 40%.

  On the other hand, when storing meat, fish, frozen food, etc. in the refrigerator compartment 100 and the vegetable compartment 500 and planning to store them for one week or more, all storage rooms are set in the freezing temperature zone, and −18 depending on the scheduled storage period. When the recommended temperature is set to ℃ or less (refrigeration performance: *** = Three Star, 3 months storage) to -6 ℃ or less (refrigeration performance: * = One Star, storage for 1 week) Will increase. However, it is possible to obtain a storage environment suitable for the user's purpose of storing more food for a long period of time.

  As described above, according to the refrigerator 1000 according to the first embodiment, the recommended set temperature is calculated based on the food storage information and the user schedule information, and after the approval or correction by the user, the set temperature is confirmed. This is reflected in the cooling control. Therefore, a customized storage environment suitable for the type and quantity of food can be realized, and the maximum energy saving effect can be obtained while maintaining the storage quality of food required by individual users. It becomes.

  In addition, when operating at the set temperature once determined by the set temperature determining means 6, as shown in the example of spinach in FIG. In use, the stored food input / display device 2 erases it as shown in FIG. Or it moves to the storage room of the low temperature environment with a longer shelf life. For example, switching to frozen storage, the stored food information is reset by the stored food input / display device 2 as shown in FIG. Then, the recommended set temperature is calculated again by the recommended set temperature calculating means 4, approved or corrected by the user by the recommended set temperature display / correcting device 5, and then set by the set temperature determining means 6. Just drive.

  As described above, even when new foods are not stored, by changing the set temperature according to changes in the storage conditions in the storage room, the preservation quality of the foods required at that time can be maintained and maximum energy saving can be achieved. An effect can be obtained.

  The operation panel 1 shown in FIG. 1 and FIG. 2 shows the stored food list shown in FIGS. 4 and 5 in the stored food input / display device 2 and the recommended set temperature display / correction device 5 shown in FIG. The relationship with the recommended set temperature is displayed. And since the influence which the storage condition in a storage room has on set temperature, ie, an energy-saving effect, can be confirmed, the effect that it becomes possible to enlighten the user about the storage method which contributes to optimal cooling operation and power saving operation is acquired. .

  Note that the recommended set temperature information, the determined set temperature information, the food storage information, and / or the user schedule information are collectively managed by the refrigerator 1000 alone. Management here means storing the above information and rearranging the stored information (the same applies hereinafter). For example, the management of the user's schedule information is to store the inputted schedule information of one or a plurality of users and rearrange the stored information for each user.

(Or that there was a plan).

  Next, an example of the operation of the refrigerator 1000 according to the second embodiment will be described with reference to FIGS. 7 and 8. However, the description of the same operation as that of the first embodiment will be omitted.

  As described in the first embodiment, since the refrigerator 1000 cannot be turned off (stops cooling) due to the property of the equipment that manages food, the user can use the power saving operation. It is necessary to raise the set temperature of each storage room according to the situation and the storage situation in the storage room. For example, a rapid cooling operation that rapidly cools the storage chamber is performed. Here, the rapid cooling operation lowers the set temperature from the original target temperature, reaches the original target temperature earlier, and reaches a lower temperature. It is a cooling operation.

  When the opening / closing frequency of the door 30 is low (less than a predetermined value), or when the amount of food stored in the storage chamber is low (less than a predetermined value), the opening / closing frequency of the door 30 is (predetermined). It is possible to perform power-saving operation without deteriorating the storage quality of food even when the set temperature is raised, compared to the case where the amount of food stored in the storage room is greater (than the value) or the amount of food stored in the storage chamber is greater (than the predetermined value). .

  Therefore, in the second embodiment, as shown in FIG. 7, the user's schedule information input by the schedule input / display device 8 in the operation panel 1 is arranged by the schedule management means 9, and the schedule information is arranged. Based on the above, the recommended set temperature calculation means 4 calculates the recommended set temperature. Thereafter, after the user approves or corrects the recommended set temperature display / correction device 5 in the operation panel 1, the set temperature is determined by the set temperature determination means 6. Then, based on the determined set temperature, by sending a control change instruction to the cooling control means 7 that controls the compressor 1001, the air conveyance device 1003, and the cold room damper 102 and other storage room dampers, The set temperature of the storage room can be changed.

  Specifically, with respect to the user's schedule shown in FIG. 8, as a control example in units of several days, (6) travel from 6/6 to 6/8 from (a) month display and (b) week display As a result, it is understood that the whole family is absent and that the door 30 is not opened and closed and the stored food does not increase during that time. Therefore, the recommended set temperature calculation means 4 calculates the recommended set temperature for raising the temperature of all the storage rooms except for the ice making room 200 and the freezing room 400, such as the storage room that may cause harmful effects when the temperature is raised. Then, the recommended set temperature display / correction device 5 in the operation panel 1 is displayed.

  Here, the set temperature determination means 6 determines the set temperature after reflecting the user's approval or, for example, correction such that the ice making chamber 200 can stop cooling and the switching chamber 300 cannot raise the temperature. . Then, based on the determined set temperature, a control change instruction for reducing the number of rotations of the compressor 1001 and the amount of conveyance air by the air conveyance device 1003 is sent to the cooling control means 7. By doing so, it is possible to carry out maximum power saving operation while maintaining the storage quality of foods required by individual users.

  In addition, as an example of the control in units of one day, (c) in the day display, as shown in the outing time zones 15a and 15b according to the steady schedule, the time zone of 8:00 to 15:00 and the sleeping time zone 16 As shown, the opening and closing of the door 30 is not normally performed in the time zone from 23: 00 to 6:00, except for sudden cases (such as going home due to illness, getting up at night and taking out a beverage). . Therefore, it is possible to carry out the power saving operation in the same manner, and the same applies to the time zone of 18:00:00 to 21:00 as shown in the outing time zone 14b due to the unsteady schedule. For this reason, by managing the user's schedule and reflecting it in the cooling control, it is possible to perform power saving operation in units of time suitable for the user's life pattern.

  Further, as a lifestyle pattern that the schedule management means 9 and the recommended set temperature calculation means 4 reflect on the recommended set temperature, in addition to the actions that all of them are related to such as going out regularly, going to sleep, and getting up, in the refrigerator 1000 that stores food, The shopping pattern, that is, the door 30 opening / closing pattern of the refrigerator 1000 that causes the rapid cooling operation is also an important control factor.

  Therefore, in the second embodiment, similar to the user schedule shown in FIG. 8, as a shopping pattern, for example, a double-working family makes a bulk purchase on the weekend, and a full-time housewife family makes shopping every day or every other day in a short cycle. The schedule management means 9 manages patterns such as

  For the weekend bulk buying pattern, instead of lowering the set temperature of each storage room on the weekend when the door 30 is frequently opened and closed and the amount of food stored in the storage room is increased, the set temperature is set toward the weekend, for example. Increase the set temperature on weekdays by gradually increasing the value. For short-cycle shopping patterns, only the scheduled shopping date is changed to a slightly lower set temperature.

  As described above, the frequency of opening and closing the door 30 and the amount of food stored in the storage chamber are estimated based on the user's schedule information, and cooling is performed according to the estimated frequency of opening and closing the door 30 and the amount of food stored in the storage chamber. By changing the control, overcooling and undercooling can be prevented, and efficient cooling becomes possible.

  At this time, when the recommended set temperature calculation means 4 performs the power saving operation for raising the set temperature of each storage room based on the user's schedule, for example, the time for going out by eating out as shown in FIG. Prior to the belt 14b (18: 00 to 21:00), it is desirable to perform a rapid cooling operation for lowering the set temperature of each storage chamber in advance to lower the temperature in the storage chamber. If the temperature of the storage room and the food in the storage room is lowered to a certain extent by the rapid cooling operation, even if the schedule is changed and the frequency of opening and closing the door 30 increases, the storage room and its storage can be performed without performing the rapid cooling operation. The temperature rise of the food inside can be suppressed. Therefore, it is possible to maintain the storage quality of food.

  FIG. 9 is an example of the calculated recommended set temperature in recommended set temperature calculation means 4 of refrigerator 1000 according to Embodiment 2 of the present invention. FIG. 9 is a trial calculation of a recommended set temperature plan for each storage room calculated by the recommended set temperature calculation means 4 by simulation. Since the user's life pattern can be assumed to some extent based on the schedule information arranged by the schedule management means 9, the recommended set temperature calculation means 4 can calculate the recommended set temperature according to the life pattern.

  In the example of FIG. 9, (1) standard: a user who uses it normally, (2) ice making unnecessary: a user who does not make ice in the refrigerator 1000, (3) limited to one month: a user who uses up the frozen food within one month (4) Freezing only: User who uses only freezer 400 (freezer only), (5) Refrigerated only: user who does not store food after freezing, (6) Villa: For long-term use, cool with odor countermeasure It shows the recommended set temperature aimed at the user.

  As shown in (2) to (6) of FIG. 9, in any of (2) to (6), (1) by performing a power saving operation for raising the set temperature of each storage room based on the user's schedule. It can be seen that a high energy saving rate (11% to 55%) that cannot be obtained in the normal operation). And it turns out that the maximum energy-saving effect is acquired, after satisfy | filling the objective that a user preserve | saves food.

Embodiment 3 FIG.
FIG. 10 is a schematic configuration diagram of a home system 2000 on which the refrigerator 1000 according to Embodiment 3 of the present invention is placed.
Hereinafter, the third embodiment will be described. Items not particularly described in the third embodiment are the same as those in the first and second embodiments, and the same reference numerals are used for the same functions and configurations. Let's say.

  As shown in FIG. 10, in-home system 2000 according to Embodiment 3 includes a room air conditioner including a refrigerator 1000, a hot water heater, an IH cooking heater, a home appliance such as a microwave oven, and a power measuring device 2002 including a power line 2006. Is connected to the system power supply 2001 to supply power.

  The power measurement device 2002 measures the power supplied to each home appliance (that is, the power consumption of each home appliance) and the total power supplied from the system power supply 2001 by using a power measurement terminal 2003 such as a CT, for example. Can be saved. Each home appliance and power measuring device 2002 has a built-in communication device 10 for external bidirectional communication with a home controller 2004 in a wired or wireless manner, or is provided and connected to the outside.

  The home controller 2004 corresponds to the “controller” of the present invention.

The communication device 10 includes a communication module such as a serial interface or a driver when communicating by wire, and a communication module such as Wi-Fi or Bluetooth (registered trademark) when communicating wirelessly. It is equipped.
The in-home controller 2004 manages the power consumption of each home appliance, the power supplied to the system power supply 2001 obtained from the power measuring device 2002 via the communication device 10, and the operating state information obtained from each home appliance. It is also possible to transmit a control change instruction to the device.

FIG. 11: is a schematic block diagram (side sectional drawing) of the refrigerator 1000 which concerns on Embodiment 3 of this invention. FIG. 11 is a cross-sectional view at the same position as in FIG.
The recommended set temperature display / correction device 5 and the schedule input / display device 8 are built in the operation panel 1 provided in the door 30 of the refrigerator compartment 100 in the second embodiment, but in the third embodiment, FIG. As shown in FIG. 2, the controller is built in the home controller 2004 and mounted on the control board 1004 provided on the back surface of the refrigerator 1000. The recommended set temperature display / correction device 5 is connected to the recommended set temperature calculation means 4 and the set temperature determination means 6 via the communication device 10, and the schedule input / display device 8 is a schedule management means 9. Are connected via the communication device 10 and communicate with each other.

  Next, an example of the operation of the refrigerator 1000 according to the third embodiment will be described with reference to FIGS. 10 and 11, but the description of the same operation as in the first and second embodiments will be omitted.

  In FIG. 10, home appliances such as a refrigerator 1000, a room air conditioner, a water heater, an IH cooking heater, and a microwave oven are operated by being supplied with electric power from a system power supply 2001. And these household appliances transmit the information of a driving | running state to the home controller 2004 by wired communication or radio | wireless communication via the communication apparatus 10 continuously or when there exists a request | requirement.

  Information on the operation state in the refrigerator 1000 includes, for example, set temperatures and actual temperature history of each storage room, operation modes with and without ice making operation and rapid cooling operation, alert information on the empty state of the water supply tank and the open state of the door 30, etc. There is. At this time, the current supplied to each home appliance is measured by the power measurement terminal 2003, and the power measuring device 2002 calculates the power consumption of each home appliance and the supply power of the system power supply 2001. Then, the calculated power information is transmitted to the home controller 2004 via the communication device 10 by wired communication or wireless communication.

The in-home controller 2004 manages the power consumption of each home appliance obtained from the power measuring device 2002, the power supplied to the system power supply 2001, and the operating state information obtained from each home appliance, and based on the information. A control change instruction is transmitted to each home appliance.
For example, when the total power consumption of each home appliance approaches the upper limit value of the supply capacity of the system power supply 2001, a power saving instruction is transmitted to a home appliance with particularly high power consumption. And about the refrigerator 1000, when it is judged that it is overcooling from the preset temperature and actual temperature history of a storeroom, the raise of preset temperature can be instruct | indicated.

  As for the refrigerator 1000 alone shown in FIG. 11, the schedule management means 9 organizes the user's schedule information input by the schedule input / display device 8 in the home controller 2004 as in the second embodiment. Based on the arranged schedule information, the recommended set temperature is calculated by the recommended set temperature calculation means 4, and the recommended set temperature display / correction device 5 in the home controller 2004 is approved or corrected by the user. Confirm the set temperature with. Then, based on the determined set temperature, by sending a control change instruction to the cooling control means 7 that controls the compressor 1001, the air conveyance device 1003, and the cold room damper 102 and other storage room dampers, The set temperature of the storage room is changed.

  Therefore, since all operations can be performed by the home controller 2004, it is not necessary to go to the place where the refrigerator 1000 is placed and operate the operation panel 1. Also, the recommended controller temperature information managed by the refrigerator 1000 alone, the determined preset temperature information, the food storage information, and / or the user schedule information can be collectively managed by the home controller 2004. Furthermore, the power consumption and operation information of each home appliance can be managed collectively. Therefore, it can be reflected in the control of other home appliances, and the effect that the configuration of the operation panel 1 can be simplified even with the refrigerator 1000 alone can be obtained.

  In addition, in the home controller 2004, in addition to the temperature information of each storage room, the input schedule information of the user, the recommended set temperature calculated based on the schedule information, the power supply information of the system power supply 2001 and the power consumption information of the refrigerator 1000 Is also displayed. Then, in addition to the user's schedule, by checking the power supply / demand situation and the corresponding control content, it is possible to educate the user on the power saving behavior.

FIG. 12 is an example of history data indicating the power consumption level of each home appliance in the home system 2000 on which the refrigerator 1000 according to Embodiment 3 of the present invention is placed. In addition, the air conditioner in FIG. 12 is a room air conditioner.
FIG. 12 simulates the daily history data of the power consumption level of each home appliance measured by the power measurement device 2002 and the total power consumption level of the home system 2000 in the home system 2000 shown in FIG. (A) is the total of home system 2000, (b) is refrigerator 1000, (c) is a room air conditioner, (d) is a water heater, (e) is an IH cooking heater, and (f) is the power consumption level of the microwave oven. is there.

  12A to 12F show simulated data 17 (17a, 17b) of the history of the power consumption level measured by the power measuring device 2002. FIG. Specifically, the simulation data 17a is simulation data of a history of power consumption levels during normal operation, and the simulation data 17b is simulation data of a history of power consumption levels after changing the cooling control of the refrigerator 1000. As in FIG. 8, the in-home system 2000 is installed in a double-family home and assumes that the home is absent during the daytime (8:00 to 18:00).

  From FIG. 12, in (e) IH cooking heater and (f) microwave oven used for cooking, power consumption suddenly occurs between 6: 00-8: 00 at breakfast and 18: 00-20: 00 at dinner Level rises. (C) The room air conditioner starts up at the time of wake-up that overlaps with breakfast and returns home that overlaps with dinner, and the power consumption level suddenly increases, and thereafter, steady operation is continued at a relatively low power consumption level. (D) It is assumed that the water heater is heated to the midnight power band except that the power consumption level slightly rises when taking a bath at night. (B) As for the refrigerator 1000, the opening and closing frequency of the door 30 increases during breakfast and dinner, so the refrigerator 1000 is cooled to avoid a temperature rise, and the power consumption level during normal operation is increased. a) As shown in the total of the home system 2000, as a result, the power consumption level during normal operation increases intensively during breakfast and dinner. Furthermore, in FIG. 12, (b) in the refrigerator 1000, it is assumed that the defrosting operation is performed at 21:00 to 23:00 at night, but when the defrosting operation also overlaps at breakfast or dinner, The possibility of tightening the power supply is increased.

  At this time, the in-home controller 2004 obtains the power consumption of each home appliance and the supply power of the system power supply 2001 from the power measuring device 2002, and the total power consumption of each home appliance approaches the upper limit value of the supply capacity of the system power supply 2001. If it is, the power saving instruction is transmitted via the communication device 10. For example, (e) IH cooking heaters and (f) microwave ovens that are cooking at breakfast or dinner are difficult to accept power-saving instructions, but they operate to consume more power during that time period. Inevitable (b) refrigerator 1000 and (c) room air conditioner can perform power saving operation.

  (B) In the refrigerator 1000, for example, when the opening / closing frequency of the door 30 of the refrigeration room 100 increases during breakfast or dinner, the cooling control unit 7 cancels the rapid cooling operation and then opens the refrigeration room damper 102. The rate is increased, and a signal for reducing the number of rotations of the compressor 1001 and the amount of air transported by the air transport device 1003 is transmitted, and cooling air is caused to flow intensively into the refrigerator compartment 100.

  By doing so, as shown in the simulation data 17b of the power consumption level history after the change of the cooling control in FIG. 12, the total power consumption of (b) the refrigerator 1000 and (a) the home system 2000 during breakfast and dinner. The level can be reduced. Furthermore, in the defrosting operation and the rapid cooling operation in which the power consumption increases, the timing at which those operations are required is predicted from the operation history, and as shown in the simulation data 17b of the power consumption level history after the cooling control change, It is implemented in advance in a time zone where the power consumption level of other household electrical appliances is low, particularly in the late-night power zone where the electricity cost per unit power is cheap, so that concentration of power consumption is avoided and the power cost is reduced.

  Here, as shown in FIG. 12, the power consumption of each home appliance is closely related to the presence / absence status of the user, that is, the user's schedule. In the third embodiment, the in-house controller 2004 collectively manages the user's schedule information input by the schedule input / display device 8 and the power consumption information of each home appliance. By doing so, the recommended set temperature is calculated reflecting both information, and after the approval or correction by the user, the set temperature can be determined.

  Therefore, by comparing the user's schedule information with the power consumption information of each home appliance, for example, a sudden schedule change or a schedule input error, or a lifestyle pattern that cannot be determined by schedule information alone (scheduled at home but due to lunch box or home delivery etc. For example, do not use cooking appliances). By doing so, it is possible to accurately correspond to the user's schedule, and it is possible to carry out optimal cooling control without excessive cooling or insufficient cooling while maintaining the preservation quality of food.

  In FIG. 11, the schedule input / display device 8 is built in the home controller 2004 and the recommended set temperature is calculated based on the user's schedule information as in the second embodiment. The stored food input / display device 2 may be built in and the recommended set temperature may be calculated based on the stored food information as in the first embodiment. Even when the stored food information and the power consumption information of each household electrical appliance are combined instead of the user's schedule information, it is the same that the recommended set temperature can be calculated according to the cooling load situation, and the same effect Is obtained.

  Further, in FIG. 10, the current supplied to each home appliance is measured by the power measurement terminal 2003, and the power measuring device 2002 calculates the power consumption of each home appliance and the supply power of the system power supply 2001. The power consumption measurement function may be mounted on the home appliance, and the power consumption information may be directly transmitted from each home appliance to the home controller 2004 via the communication device 10. This eliminates the need for the power measurement device 2002 and the power measurement terminal 2003 shown in FIG. 10, so that it is possible to simplify the home system 2000 and to construct it at low cost.
