Description

  The present invention relates to a power feeding system for a solar power generation device, and an information processing terminal device, a washing / drying machine, and a refrigerator that are network-connected to the solar power generation device.

  In recent years, the number of solar power generation devices installed in ordinary households has increased. At home, home appliances are operated using the power generated by the attached photovoltaic power generation device. In this manner, by using the solar power generation device, it is possible to take a part in helping to counter global warming. Moreover, in order to cover the electric power used in the home with the solar power generator as much as possible, it is necessary to increase the power generation amount of the solar power generator. On the other hand, by using the electric power generated by the solar power generation apparatus without waste, most of the electric power used in the home can be covered by the solar power generation apparatus.

  Japanese Patent Application Laid-Open No. 4-130507 (Patent Document 1) describes a solar cell driven device that can efficiently use the power generated by a solar power generation device. A solar cell drive type device described in Japanese Patent Laid-Open No. 4-130507 (Patent Document 1) includes a solar cell, a main device as a home appliance, and a sub device. The main device and the slave device are devices that use the power generated by the solar cell. When the operation of the main device is stopped or the surplus in the amount of power generated by the solar cell occurs, the solar cell driven device operates the slave device by using the power generated by the solar cell.

  On the other hand, various household electrical appliances such as air conditioners, refrigerators, lighting devices, and washing machines used in general households are required to reduce power consumption (that is, to save energy) as a measure against global warming. Has been. In addition, by connecting various home appliances and information processing terminal devices via a network, network technology configured to enable communication between various home appliances and information processing terminal devices, or network technology Home appliances are being developed. According to such a technique, the information processing terminal device collects information such as the power consumption and the operation mode of each home appliance, and controls each home appliance based on the collected information.

  As an example of home appliances that support network technology, a laundry dryer starts operation so that the requested end time for washing or drying is achieved even if the end time for washing or drying is requested by the user. And it is only necessary to drive. In addition, the end time of washing or drying requested by the user is often relatively early rather than immediately after clothes or the like are put into the washing / drying machine. In this way, the time period during which the washing / drying machine must actually operate is not so limited as compared with that of other types of home appliances.

  In the washing and drying machine, especially when drying is performed in addition to washing, the role of the washing and drying machine is fulfilled. Therefore, only the washing is carried out during the time when the washing and drying machine must actually operate. There are no further restrictions compared to the case. Therefore, the user can use the electric power generated by the solar power generation device without waste by operating the washing and drying machine in a time zone when the power generation amount of the solar power generation device is excessive. As described above, the washing / drying machine has a relatively high degree of freedom with respect to the user's desire to operate in a time zone in which surplus in the amount of power generated by the photovoltaic power generation apparatus occurs. However, in a washing / drying machine, when drying is performed in addition to washing, electric power used increases.

  Japanese Patent Application Laid-Open No. 2007-236538 (Patent Document 2) describes a fully automatic washing and drying method that allows a user to automatically drive in an optimal time zone according to the situation in consideration of the importance of electricity charges and life rhythm. The machine is listed. Japanese Patent Application Laid-Open No. 2007-236538 (Patent Document 2) describes a fully automatic washing / drying machine that detects the weight of clothes to be washed, and a necessary operation for all processes based on the detected weight of clothes. Based on the operation required time prediction means for predicting the required time, the priority time zone storage means for storing the priority time zone where the unit price of electricity is low, and the operation required time and the priority time zone predicted by the operation required time prediction means, Driving time zone calculating means for calculating the driving start time and expected driving end time of each mode and presenting it to the user for a plurality of driving modes divided according to how to use the priority time zone, and driving time zone calculating means presented Washing and drying means for starting the operation at the calculated operation start time for the operation mode selected by the user based on the information and continuously executing all the steps.

  According to the fully automatic washer / dryer described in Japanese Patent Application Laid-Open No. 2007-236538 (Patent Document 2), the user can save electricity charges by selecting an optimal operation mode according to the situation. , Can keep the rhythm of life. Moreover, the fully automatic washing dryer described in Unexamined-Japanese-Patent No. 2007-236538 (patent document 2) is communication which receives the information regarding the electric power generation amount of auxiliary power supply apparatuses, such as a fuel electric cogeneration system and a solar cell cogeneration system. Equipment. The operation mode includes a special mode in which operation is started when the amount of generated power received by the communication device exceeds a predetermined value. When a special mode is selected by the user, the washing and drying means starts operation when the amount of generated power received by the communication device exceeds a predetermined value and continuously executes all the steps. Thus, the fully automatic washing and drying machine described in JP 2007-236538 A (Patent Document 2) is provided by providing a special mode in which the generated power of the cogeneration system with a low unit price of electric power can be used. In addition, the electricity bill can be further saved.

JP-A-4-130507 JP 2007-236538 A

  Generally, the amount of power generated by a solar power generation device changes every moment due to the influence of the time of day and the weather. In addition, the power consumption of home appliances used in the home changes every moment. For example, even if the photovoltaic power generator is generating a sufficiently large amount at any point in time, it is assumed that the amount of power generation has decreased after some time has passed since that point. The Therefore, the difference between the amount of power consumed by each home appliance and the amount of power generated by the solar power generator also changes every moment. On the other hand, when taking into account the actual operation of a washing / drying machine among household electrical appliances, a constant power is supplied to the washing / drying machine in a continuous time period from the start of washing to the completion of drying. is necessary.

  In the solar cell drive type device described in JP-A-4-130507 (Patent Document 1), the solar cell drive type device has a surplus in the amount of power generated by the solar cell when the operation of the main device is stopped. In some cases, the slave device is operated by using the electric power generated by the solar cell. However, the solar cell drive type device described in Japanese Patent Application Laid-Open No. 4-130507 (Patent Document 1) operates the slave device according to the operation state of the main device at an arbitrary time and the power generation amount of the solar cell. ing.

  Further, in the fully automatic washing and drying machine described in Japanese Patent Application Laid-Open No. 2007-236538 (Patent Document 2), the washing and drying unit is configured to generate power received by the communication device when a special mode is selected by the user. When the electric energy exceeds a predetermined value, the operation is started and all the processes are continuously executed. However, even if the generated power amount falls below a predetermined value after the operation of the fully automatic washing and drying machine is started by determining that the generated power amount has exceeded a predetermined value, the operation is not stopped. The operation is continued until the last step is finished. However, it is unclear whether the electric power supplied from the commercial power source or the electric power generated by the auxiliary power feeding device is used while the operation is continued. As described above, also in the fully automatic washing and drying machine described in Japanese Patent Application Laid-Open No. 2007-236538 (Patent Document 2), the amount of power generated by the auxiliary power supply device at an arbitrary time is the start of washing of the fully automatic washing and drying machine. It is used for such judgment.

  As described above, when considering the actual operation of the washing / drying machine, the washing / drying machine needs a certain amount of power in a continuous time period from the start of washing to the completion of drying. . In other words, the information processing device grasps the power generation amount of the solar power generation device only at an arbitrary point of time, thereby efficiently using the power generated by the solar power generation device when operating the washing dryer. I can't say.

  When considering that the defrosting operation is actually performed in the refrigerator, constant power is required for the refrigerator in the continuous time period from the start of the defrosting operation to the end thereof. That is, only at an arbitrary time point, the information processing device grasps the power generation amount of the solar power generation device, thereby efficiently using the power generated by the solar power generation device when the defrosting operation is performed. I can't say.

  Furthermore, when operating a plurality of home appliances such as a washing and drying machine and a refrigerator in accordance with a time zone in which the power generation amount of the solar power generation device is surplus, the power generation of the solar power generation device and the plurality of home appliances It is necessary to consider the power consumed for the operation of the equipment.

For the washing / drying machine 900, the information transmission unit 122 transmits information about the operation start time determined by the determination unit 127.

  Next, the control processed by the washing / drying machine 900 will be described using a flowchart. As shown in FIG. 8, in step S101, the laundry is put into the rotating drum 932 (see FIG. 3) by the user. In step S102, an operation mode or a washing course of the washing / drying machine 900 is selected by operating the mode selection button 923 or the course selection button 922 of the operation unit 920 (see FIG. 5). Examples of operation modes include a washing process, a rinsing process, and a mode that performs only washing including a dehydration process, or a mode that performs a drying process in addition to washing, a washing process, a rinsing process, a dehydration process, And any one of the drying strokes is set to a mode longer than the normal operation, or any one of the washing stroke, the rinsing stroke, the dehydration stroke, and the drying stroke is set shorter than the normal operation. A plurality of modes are included such as whether the mode is a mode that has been set or a mode that uses remaining hot water in the bath.

  In step S103, it is determined whether or not the operation completion desired time is input by operating the time selection buttons 926 and 927. If it is determined in step S103 that the desired operation completion time has been input, the process proceeds to step S104. In step S104, the input operation completion desired time is stored in the storage unit 951. On the other hand, when it is determined in step S103 that the operation completion desired time is not input, the process proceeds to step S105.

  In step S105, it is determined whether or not the start button 921 (see FIG. 5) has been operated. If it is determined that the start button 921 is pressed, the process proceeds to step S115. The fact that the start button 921 has been pressed means that the user has selected the start of the operation such as the washing process without causing the information processing terminal device 100 (see FIG. 6) and the washing / drying machine 900 to communicate with each other. Means.

  On the other hand, if it is determined in step S105 that the start button 921 is not operated, the process proceeds to step S106. In step S106, it is determined whether or not the automatic button 924 is operated. If it is determined that the automatic button 924 is pressed, the process proceeds to step S107. The fact that the automatic button 924 has been pressed means that, as will be described later, the information processing terminal device 100 (see FIG. 6) and the washing / drying machine 900 communicate with each other to surplus the amount of power generated by the solar power generation device 2. This means that the user desires to operate the laundry dryer 900 using, or to operate the laundry dryer 900 in the midnight time zone when the unit price of electricity is low.

  If it is determined in step S106 that the automatic button 924 has not been pressed, the process returns to step S105.

  In step S107, processing for measuring the capacity of the laundry is performed. The process in step S107 is a process necessary for determining the amount of detergent suitable for the laundry volume, and is based on the laundry course, the operation mode, and the laundry volume selected in step S102. The time for the laundry dryer 900 to actually operate is determined. After the process of step S107 is completed, the amount of detergent corresponding to the laundry capacity is displayed on the display unit 910 (see FIG. 4). The user may put the detergent after step S107 and before step S114 (see FIG. 9).

  Subsequent to step S107, step S108 is performed. In step S108, the operating time information set according to the laundry capacity or each operation mode and stored in the storage unit 951 (see FIG. 6) is transmitted to the information processing terminal device 100. Furthermore, when the operation completion desired time information is stored in the storage unit 951 in step S104, the operation time information including the information on the operation completion desired time is transmitted to the information processing terminal device 100 in step S108.

  Note that the desired operation completion time is not limited to being set by the user operating time selection buttons 926 and 927 of operation unit 920 (see FIG. 5). For example, information about the desired driving completion time may be transmitted to the information processing terminal device 100 from a portable information terminal such as the smart phone 10 (see FIG. 7) having higher operability. When a portable information terminal such as the smartphone 10 is used, the information about the operation completion desired time is stored in the information processing terminal device 100 by step S117 even after the operation mode or the like is selected in step S102. It only needs to be sent. Moreover, each operation mode etc. may be selected in step S102 by operation of the smart phone 10. In this way, the information processing terminal device 100 can receive information about the desired driving completion time from the smartphone 10.

  Further, the information processing terminal device 100 may receive information about the desired operation completion time a plurality of times until step S117 even after the operation mode or the like is selected in step S102. That is, the operation completion desired time once selected may be changed before the operation start desired time arrives. In this way, the information processing terminal device 100 can receive information about the desired operation completion time from the smartphone 10 or the washing / drying machine 900 a plurality of times.

  Subsequent to step S108, the operation start time of the washing / drying machine 900 (see FIG. 3) is set in step S110 (see FIG. 9). As will be described later, the operation start time is set by the information processing terminal device 100 (see FIG. 7). In step S111 after step S110, information on the operation start time is transmitted from the information processing terminal device 100, and the information receiving unit 955 of the control unit 950 receives the information on the operation start time.

  Subsequent to step S111, in step S112, the operation completion time or the operation start time is displayed on the time display unit 912 of the display unit 910 (see FIG. 4). Whether the time displayed on the time display unit 912 is the operation start time or the operation completion time is distinguished by information such as characters displayed on the title unit 911. The time displayed on the title section 911 is switched between the operation completion time and the operation start time each time the mode selection button 923 is operated, for example. However, the operation completion time and the operation start time displayed on the title part 911 may be switched by operating other buttons (not shown), or the automatic button 924 or the course selection button 922 is operated. May be switched. As described above, the display unit 910 of the washing / drying machine 900 (see FIG. 6) displays the operation start time determined by the information processing terminal device 100, or the washing / drying machine 900 corresponding to the operation start time and the operation time information. Displays the operation completion time.

  The user of the washing / drying machine 900 confirms the time displayed on the time display unit 912 to drive at the displayed operation completion time after the washing / drying machine 900 is operated in the selected operation mode and washing course. Whether or not to accept the completion of the operation or the start of the operation at the displayed operation start time can be selected.

  When the user does not approve the operation completion time or the operation start time displayed on the time display unit 912, the user operates the cancel button 929 (see FIG. 5) (see step S113). Thereby, the user can start the operation of the washing and drying machine 900 immediately. On the other hand, when the user approves the operation completion time or the operation start time displayed on the time display unit 912, the user operates the OK button 928 (see FIG. 5) (see step S116). Thereby, the user can start driving at the approved driving start time, or can complete driving by the approved driving completion time.

  In the present embodiment, when the cancel button 929 is pressed, an operation such as a washing process is started immediately. However, when there are a plurality of power surplus time zones that can cover all the power for the operation time, or when it is possible to set a plurality of operation times of the washing and drying machine 900 in the power surplus time zone. When the estimated power surplus time zone is relatively long, any one of a plurality of operation start times may be selected and determined by the user. In such a case, another operation start time or operation completion time may be displayed by pressing the cancel button 929 with respect to the displayed operation start time or operation completion time. Thus, when the information processing terminal device 100 and the washing / drying machine 900 are configured, the user can select a more convenient time zone.

  After step S116, the washing / drying machine 900 is in a standby state until the operation start time comes. If it is determined in step S117 that the operation start time has arrived, the process proceeds to step S114. In step S114, operation in the operation mode selected in step S102 is started.

  By the way, in step S115, the process for measuring the capacity | capacitance of the laundry is performed similarly to step S107. After the process of step S115 is completed, the amount of detergent corresponding to the laundry capacity is displayed on the display unit 910 (see FIG. 4). The user may put the detergent after step S115 and before step S114 (see FIG. 9).

  In this embodiment, the operation of the washing and drying machine 900 is immediately started after step S115 by shifting to step S114 after step S115. However, when it is determined in step S103 that the desired operation completion time has been input, the start of operation may be waited until the desired operation time arrives. That is, a step similar to step S117 may be provided between step S115 and step S114. In this way, a general reserved operation can be realized in the washing / drying machine 900.

  Next, the control for setting the time for starting the operation of the washing / drying machine 900, that is, the control processed by the information processing terminal device 100 will be described using a flowchart. As shown in FIG. 10, in step S201, the information receiving unit 121 (see FIG. 7) of the information processing terminal device 100 transmits the information to the information processing terminal device 100 from the information transmitting unit 953 (see FIG. 6) of the washing and drying machine 900. Received operating time information. Furthermore, when it is determined in step S103 (see FIG. 8) that the operation completion desired time has been input, the information receiving unit 121 provides information on the operation completion desired time desired by the user as the operation time information. Is further received from the information transmission unit 953 (see FIG. 6).

  Subsequent to step S201, it is determined in step S202 whether or not information on the desired operation completion time has been received from the information transmission unit 953. That is, in step S202, it is determined whether or not the desired operation completion time is set. If it is determined in step S202 that the desired operation completion time is set, the process proceeds to step S203. If it is determined in step S202 that the desired operation completion time is not set, the process proceeds to step S209.

  In step S203, the time transition of the electric power generated by the photovoltaic power generation apparatus 2 from that time to the operation completion desired time is estimated with reference to the time when the operation time information is transmitted from the washing / drying machine 900. The information processing terminal device 100 accumulates the temporal transition of the generated power during a certain past period as data by constantly monitoring the generated power of the solar power generation device 2. The average value of the temporal transition of the generated power over a certain period in the past is calculated by the calculation unit 123 based on the accumulated data, so that the temporal transition of the generated power from the present to the desired operation completion time is estimated. Is done.

  For example, the certain period in the past may be one week or one month. In addition, when the certain period in the past is, for example, January, the data of the temporal transition of the generated power may be distinguished for each day of the week. Alternatively, the information processing terminal device 100 acquires weather information via, for example, the external Internet, and calculates an average value of temporal transitions for several days that were the same weather during a certain period in the past. By doing so, the temporal transition of the generated power from the present time to the desired operation completion time may be estimated.

  Subsequently, in step S204, with reference to the time point when the operation time information has been transmitted from the washing / drying machine 900, the time transition of the power used by other home appliances from that point to the operation completion desired time is estimated. . The information processing terminal device 100 accumulates the time transition of the power used by the other home appliances as data in the past certain period by constantly monitoring the power used by the other home appliances excluding the washing and drying machine 900. ing. The average value of the temporal transition of the power used by other home appliances in a certain past period is calculated by the calculation unit 123 based on the accumulated data, so that the power used from the present to the desired operation completion time Is estimated.

  In addition, when the day is a weekday, the average value of the time transition for several days that were a weekday in a certain period in the past is calculated, so that from the current weekday to the desired completion time The temporal transition of the used power may be estimated. Similarly, when the current day is a holiday, the desired time of completion of operation from the present day as a holiday is calculated by calculating the average value of the temporal transition of several days that were a holiday during a certain period in the past. The temporal transition of the power consumption up to may be estimated. Furthermore, not only the distinction between weekdays and holidays, but also the temporal transition of the used power distinguished for each day of the week may be estimated.

  On the other hand, in step S209, the time transition of the power generated by the solar power generation device 2 is estimated from the time point, for example, 24 hours later, based on the time point when the operation time information is transmitted from the washing / drying machine 900. . Note that the estimated temporal transition is not limited to 24 hours from the present time, and may be another time. Since the time of 24 hours after the current time is set as in the present embodiment, the laundry dryer is put into the rotating drum 932 (see step S101 in FIG. 8) and within one day at the latest. It is possible to complete 900 operations.

  Subsequently, in step S210, with reference to the time point at which the operation time information has been transmitted from the washing / drying machine 900, the temporal transition of power used by other home appliances from that point to 24 hours later is estimated.

  Like these step S203-step S204 and step S209-step S210, the information processing terminal device 100 (refer FIG. 7) is the information of the time transition of the past electric power generation amount of the solar power generation device 2, and refrigerator 5 And the time zone when surplus in the generated power of the solar power generation device 2 is estimated from the information of the temporal transition of the past power consumption of the television 6, the air conditioner 7, and the lighting device 8. Moreover, the memory | storage part 124 of the information processing terminal device 100 memorize | stores the result of the estimated time slot | zone as electric power surplus time slot | zone information.

  Here, “the past” refers to a time point before the time point when the operation time information is transmitted from the washing / drying machine 900. Alternatively, the “past” may be a time point before the time point when the information processing terminal device 100 estimates the power surplus time zone.

  Subsequent to step S204, in step S205, the estimated temporal transition of the generated power of the photovoltaic power generation apparatus 2 and the estimated temporal transition of the used electric power of the other household electrical appliance are calculated (see FIG. 7). ) Is estimated, a power surplus time zone as a time zone in which surplus power is generated is estimated.

  Subsequent to step S205, in step S206 (see FIG. 11), it is determined whether there is a power surplus time zone corresponding to the operation time of the washing / drying machine 900 corresponding to the operation mode or the like. While the washing / drying machine 900 is in operation, predetermined power is required. Therefore, in step S206, it is determined whether or not there is a power surplus time zone that can cover power for a predetermined time required according to the operation mode or the like. If it is determined in step S206 that there is a power surplus time zone that can cover all power for the operating time, the process proceeds to step S207. On the other hand, if it is determined that there is no power surplus time zone that can cover all power for the operating time, the process proceeds to step S211.

  In step S <b> 206, the determination unit 126 (see FIG. 7) of the information processing terminal device 100 operates the operation time information including information on the desired operation completion time received by the information reception unit 121 and the power surplus time zone stored by the storage unit 124. Based on the information, it is determined whether or not there is a power surplus time zone that can cover the power consumed during the operation time according to the operation mode of the washing / drying machine 900 by the operation completion desired time. However, if it is determined in step S202 that the desired operation completion time is not set, the operation time information received by the information receiving unit 121 may not include information on the desired operation completion time.

  In step S207, the operation start time of the washing / drying machine 900 is determined. According to the operation start time determined in step S207, the operation from the start to the completion of the operation of the washing / drying machine 900 is achieved in the power surplus time zone that can cover all the electric power for the operation time according to the operation mode and the like. can do.

  As described above, the information processing terminal device 100 is based on the operating time information received from the washing / drying machine 900 as information on the time during which the washing / drying machine 900 actually operates, and the stored power surplus time zone information. The operation start time is determined.

  In addition, when there are a plurality of power surplus time zones that can cover all the power for the operation time, or when it is possible to set a plurality of operation times of the washing dryer 900 in the power surplus time zone. When the estimated power surplus time zone is relatively long and the operation completion desired time is not set, for example, the earliest time among a plurality of times is determined as the operation start time. However, at this time, for example, the latest time among a plurality of times may be selected. As described above, when there are a plurality of power surplus time zones that can cover all the power for the operation time, or it is possible to set a plurality of operation times of the washing dryer 900 in the power surplus time zone. In the case where the estimated power surplus time zone is relatively long, any one of the plurality of operation start times is selected and determined by the user in step S112, step S113, and step S116 shown in FIG. May be. In addition, when the operation completion desired time is set, the operation start time that satisfies the operation completion desired time is selected.

  On the other hand, in step S211, whether or not the information processing terminal device 100 is set in advance so that at least the washing / drying machine 900 among the plurality of home appliances uses power in a time zone in which the electricity rate such as midnight power is relatively low. Is determined. In the power supply system 1, the time zone of power supplied from the commercial power supply 4 includes a midnight time zone, which is a time zone in which a power unit price lower than the power unit price in the normal time zone is set.

  When the information processing terminal device 100 is set so that the washing / drying machine 900 uses midnight power, the process proceeds to step S212. In step S212, the operation start time is determined based on the midnight time zone. The operation start time determined in step S212 is a time at which the operation of the washer / dryer 900 is started in the midnight time zone. According to the operation start time determined in step S212, the operation of the washer / dryer 900 is started from midnight. Alternatively, the operation start time determined in step S212 uses the power in the midnight time zone after using as much power as possible in the power surplus time zone.

  The determination unit 127 (see FIG. 7) of the information processing terminal device 100 has a power surplus time zone in which the determination unit 126 can cover the power consumed during the operation time according to the operation mode of the washing / drying machine 900 or the like. If it is determined that the power does not exist (see step S206), the difference between the power consumed during the operation time and the surplus power generated by the solar power generation device 2 is washed and dried from the commercial power source 4. A signal for switching the power supplied from the commercial power supply 4 and the power generated by the solar power generation device 2 to the power supply switching device 3 is transmitted to the information transmission unit 122 so as to be supplied to the machine 900. The power supply switching device 3 receives a signal based on the signal from the information transmission unit 122. Thereby, the power of the difference between the power consumed during the operation time corresponding to the operation mode and the surplus power generated by the solar power generation device 2 is supplied from the commercial power supply 4 to the washing and drying machine 900. The electric power supplied from the commercial power source 4 and the electric power generated by the solar power generation device 2 are switched by the power source switching device 3.

  In addition, when it is determined NO in step S206 (see FIG. 11) and YES is determined in step S211 (see FIG. 11), the determination unit 127 supplies the washing and drying machine 900 with power in the midnight time zone. A signal for use is transmitted to the information transmitter 122. The power supply switching device 3 receives a signal based on the signal from the information transmission unit 122. The power supply switching device 3 switches between the two powers so that power is supplied from the commercial power source 4 to the home appliances including the washer / dryer 900 from the time when the surplus of the generated power of the solar power generation device 2 is insufficient at the latest. .

  On the other hand, if it is determined in step S211 that the information processing terminal device 100 is set not to use late-night power, the process proceeds to step S213. In step S213, the operation start time is determined based on the time zone in which the power in the power surplus time zone is consumed most efficiently. According to the operation start time determined in step S213, the commercial power source 4 can cover the shortage while using as much power as possible in the power surplus time zone.

  In step S208, the information on the operation start time determined in step S207, step S212, or step S213 is transmitted from the information processing terminal device 100 to the washing and drying machine 900 (see FIG. 7).

  The information of the operation start time transmitted from the information processing terminal device 100 in step S208 is received by the information receiving unit 955 (see FIG. 6) of the washing / drying machine 900 (see step S111 in FIG. 9). As described above, in step S112 (see FIG. 9), the operation start time determined by the information processing terminal device 100 or the operation start time and the operation are displayed on the display unit 910 of the washing and drying machine 900 (see FIG. 6). The operation completion time of the washer / dryer 900 corresponding to the time information is displayed.

  Furthermore, the information processing terminal device 100 is configured to control among the plurality of home appliances to be controlled according to the difference between the estimated surplus of the generated power of the solar power generation device 2 and the power consumption of the plurality of home appliances. Some or all of the home appliances may be selected. When the information processing terminal device 100 selects a plurality of home appliances, the difference between the power consumption of the selected home appliances and the estimated surplus power generated by the solar power generation device 2 Accordingly, it is selected to switch between sequentially supplying surplus power to each of the plurality of home appliances and simultaneously supplying surplus power to any or all of the plurality of home appliances. The information processing terminal device 100 can control a plurality of home appliances. By doing in this way, in the electric power feeding system 1, the electric power which the solar power generation device 2 generated can be utilized efficiently.

  The rotation axis of the rotary drum 932 of the washing / drying machine 900 may extend in a substantially vertical vertical direction.

  In the present embodiment, the information processing terminal device 100 may include a display unit as shown in FIG.

  In this embodiment, the operation time of the washing / drying machine 900 is a time during which the washing / drying machine 900 as a predetermined home appliance actually operates. The operation time is the time from the start of the first stroke to the completion of the operation among the washing stroke, the rinsing stroke, the dewatering stroke, or the drying stroke. Furthermore, the operation time information is information on a time during which the washing / drying machine 900 is actually operated. The operation time information is information transmitted from the information transmission unit 953 of the washing / drying machine 900 and is received by the information reception unit 121 of the information processing terminal device 100.

  Since the time during which the washing / drying machine 900 actually operates differs depending on the selected laundry course, the operation time varies depending on the selected laundry course. In addition, when the time required for each stroke is appropriately selected by the user, the operation time varies depending on the time of each selected stroke. Furthermore, in the washing / drying machine 900, the operation time differs depending on, for example, each operation mode because the time of the washing process, the rinsing process, the dehydration process, or the drying process differs for each operation mode. Moreover, since the quantity of the water supplied to the water tank 931 (refer FIG. 3) changes with the capacity | capacitances of the laundry W, the operation time differs.

  In addition, the position where the control part 950 is arrange | positioned in the washing dryer 900 is not specifically limited. The control unit 950 shown in FIG. 3 is shown schematically and may be any unit that exhibits a desired function as described above.

(Second Embodiment)
In the second embodiment, an example of the predetermined home appliance is the refrigerator 5. Examples of other home appliances are home appliances excluding the refrigerator 5. Although not illustrated, the plurality of home appliances may include a plurality of similar home appliances (for example, a plurality of televisions 6 may be provided). As will be described below, the defrosting operation of the refrigerator 5 is performed in a time zone in which surplus in the generated power of the solar power generation device 2 occurs, so that the power generated by the solar power generation device 2 is generated in the power feeding system 1. It can be used efficiently. In addition, performing defrost operation in the refrigerator 5 can be paraphrased as operating the refrigerator 5 so as to perform defrost operation.

  FIG. 12 shows the entire refrigerator 5 as an example of home appliances compatible with network technology. The refrigerator 5 has a refrigeration function in addition to a refrigeration function. In FIG. 12, hatching indicating a cross section is omitted.

  As shown in FIG. 12, the entire refrigerator 5 is covered with a heat insulating box 51. A refrigerator compartment 510 is arranged in the upper stage of the refrigerator 5, an ice making room 503 is arranged in the middle stage, and a freezing room 505 is arranged in the lower stage. Further, a chilled chamber 514 maintained at a chilled temperature zone (about −3 ° C.) is disposed at the lower part of the refrigerator compartment 510. The inside of the freezer compartment 505 communicates with the inside of the ice making room 503. In addition, the inside of the freezer compartment 505 is configured so that stored items such as food stored in the freezer compartment 505 can be stored frozen. In the freezer compartment 505 and the ice making room 503, a storage case 511 for storing stored items is arranged. In the refrigerator compartment 510, a plurality of storage shelves 512 on which stored items are placed are arranged.

  A cool air passage 521 is disposed behind the freezer compartment 505. A cold air passage 522 communicating with the cold air passage 521 is disposed behind the refrigerator compartment 510. In the heat insulation box 51 of the refrigerator 5, a compressor 523 is disposed below the cold air passage 521. An evaporator 524 connected to the compressor 523 is disposed in the cold air passage 521. When the compressor 523 is driven, the refrigerant circulates through a condenser, an expander, and an evaporator 524 (not shown). The refrigerant is, for example, isobutane. The refrigeration cycle is operated by the circulation of the refrigerant. When the refrigeration cycle is operated, in the evaporator 524 on the low temperature side of the refrigeration cycle, heat is exchanged between the air flowing through the cold air passage 521 and the refrigerant, thereby generating cold air. Thus, the refrigerating cycle which produces | generates cold air is comprised by the compressor 523, the evaporator 524, the condenser (not shown), and the expander (not shown).

  A blower 525 is disposed in the cold air passage 521. A blower 526 is disposed in the cold air passage 522. The cold air generated by the evaporator 524 is supplied to the freezing room 505 and the ice making room 503 through the cold air passage 521 when the blower 525 is driven. The cool air generated by the evaporator 524 is supplied to the refrigerating chamber 510 through the cool air passage 522 when the blower 526 is driven.

  The refrigerator 5 includes a heater 527 as a heating unit. The heater 527 is constituted by, for example, a thermal radiation type glass tube heater. However, the configuration of the heater 527 is not particularly limited, and other heaters may be used.

  With the above-described configuration, the refrigerator 5 uses the compressor 523, the evaporator 524, and the like to store the food, mainly in the same manner as a general refrigerator, so that the refrigerator room 510 and the freezer room 505 are separated. It is cooling. Among the cooling operations for cooling the refrigerator compartment 510 and the freezer compartment 505, for example, when the refrigerator compartment 510 is cooled, the temperature of the refrigerator compartment 510 reaches a predetermined temperature or higher in order to keep the temperature of the refrigerator compartment 510 at a low temperature. Sometimes it is started and stopped when it reaches below another predetermined temperature. The cooling operation occupies most of the power consumed by the refrigerator 5.

  Further, the refrigerator 5 removes frost attached to the evaporator 524 by an operation called defrosting. The defrosting operation is an operation for removing frost using the heat of the heater 527. The defrosting operation occupies a relatively large portion of the power consumed by the refrigerator 5.

  A general conventional refrigerator defrosting operation start condition is, for example, that the integrated value of the time during which the cooling operation is performed is a predetermined value, or a predetermined time after the previous defrosting operation ends. It is after the elapse of time. The time interval from the end to the start of the defrosting operation and the operation time required for the defrosting operation depend on the performance, capacity, use conditions, etc. of the refrigerator. However, in general, the defrosting operation is performed about once a day or every two days. Moreover, the operation time required for the defrosting operation is generally about several tens of minutes. That is, in a general conventional refrigerator, a defrosting operation that requires several tens of minutes is performed once every two days. Thus, the operation time required for the defrosting operation is extremely short compared to the time interval from the end to the start of the defrosting operation.

  For example, when the time interval from the end of the defrosting operation to the start of the next time is shortened, the defrosting operation is started in a state where a large amount of frost is not generated. However, since the frost is not generated in such a large amount in such a case, the operation time of the defrosting operation can be shortened.

  On the contrary, when the time interval from the end of the defrosting operation to the next start is extended, the defrosting operation must not be started in a state where more frost is required than the defrosting amount. This may adversely affect the cooling operation. Therefore, it is possible to extend the time interval from the end of the defrosting operation to the start of the next defrosting operation to such an extent that the cooling operation is not adversely affected.

  On the other hand, the operation time of the cooling operation is longer than the time when the cooling operation is not performed. In addition, since the cooling operation is an operation that directly affects the temperature inside the refrigerator 5, the change of the start timing of the cooling operation cannot be easily realized.

  Thus, even if the start time of the defrosting operation is changed in the refrigerator 5, the refrigerator 5 is not significantly affected. That is, changing the start time of the defrosting operation in the refrigerator 5 is an effective means for the refrigerator 5 to efficiently consume power.

  As will be described below, the refrigerator 5 is configured to be able to change the start time of the defrosting operation in accordance with a time zone in which surplus in the amount of power generated by the solar power generation device 2 occurs.

  As shown in FIG. 13, the refrigerator 5 includes a control unit 550. The control unit 550 includes an information reception unit 551, a storage unit 552, a calculation unit 553, a timer 554, an information transmission unit 555, an operation control unit 556, and an operation state detection unit 559. The timer 554 has a function as a clock.

  The information receiving unit 551 receives a signal transmitted from the information processing terminal device 100. The storage unit 552 stores at least information on the past defrosting operation time and information on the time of the cooling operation performed in the past. The calculating unit 553 calculates a numerical value necessary for controlling the refrigerator 5 based on the information received by the information receiving unit 551, the time measured by the timer 554, and the information stored in the storage unit 552. Moreover, the determination about the control required for the driving | operation of the refrigerator 5 is determined by the calculating part 553 which has a function of a determination part.

  As will be described later, the calculation unit 553 calculates the operation time of the current defrosting operation as an estimated value based on the past defrosting operation time and the time interval from the end of the previous defrosting operation to the current time. . Furthermore, the calculating part 553 calculates the start time limit of a defrost operation based on at least the past defrost operation time. In addition, the calculation unit 553 calculates the completion restriction time of the defrosting operation by adding the estimated current defrosting operation time to the start restriction time.

  The calculation result of the calculation unit 553 is stored in the storage unit 552. The operation control unit 556 includes a compressor 523, an evaporator 524, a heater 527, a blower 525, and a blower so that a cooling operation and a defrosting operation are performed based on information such as a calculation result stored in the storage unit 552. 526 is controlled. The operation control unit 556 includes a cooling operation control unit 557 that controls the cooling operation, and a defrosting operation control unit 558 that controls the defrosting operation.

  The operation state detection unit 559 detects the control state of the operation control unit 556 for the defrosting operation or the cooling operation. Information about the result detected by the operating state detection unit 559 is stored in the storage unit 552.

  On the other hand, the information transmission unit 555 transmits the information on the defrosting operation time and the information on the completion time limit as the calculation result of the calculation unit 553 to the information processing terminal device 100.

  In addition, the integrated value (Ti described later) of the past cooling operation and the predetermined time (Tp described later) after the last defrosting operation is completed are controlled by the operation control unit 556. Is calculated by the operation unit 553 calculating the time during which the operation state detection unit 559 detects the operation state and the operation control unit 556 continues the control state. The integrated value (Ti) of the calculated time and information on the predetermined time (Tp) are stored in the storage unit 552.

  The information receiving unit 551 receives information on the start time of the defrosting operation transmitted from the information processing terminal device 100 and information on the estimated power surplus time zone. A defrosting operation is performed in the refrigerator 5 based on the information received by the information receiving unit 551.

  In addition, the information received by the information receiving unit 551 includes information for notifying the refrigerator 5 that the power surplus time zone does not exist when the estimated power surplus time zone is shorter than the defrosting operation time. Whether or not there is is determined by the calculation unit 553. When the calculation unit 553 determines that information for notifying that the power surplus time zone does not exist is included in the storage unit 552, information for advancing the start time of the next defrosting operation is stored in the storage unit 552. Stored.

  On the other hand, as illustrated in FIG. 7, the information processing terminal device 100 includes a control unit 120. The information receiving unit 121 of the control unit 120 receives information on the current defrosting operation time from the refrigerator 5 as the operation time information. The information receiving unit 121 also includes information on the temporal transition of the amount of power generated by the solar power generation device 2 and other home appliances (for example, the TV 6, the air conditioner 7, the lighting device 8, and the washing and drying machine 900 (see FIG. 1). )) And information on temporal transition of power consumption.

  The calculation unit 123 receives the information on the temporal transition of the past power generation amount of the photovoltaic power generation apparatus 2 and the information on the temporal transition of the past power consumption amount of the other home appliances received by the information reception unit 121. Based on this, a time zone in which surplus power is generated is estimated. In this way, the information processing terminal device 100 generates power from the information on the temporal transition of the past power generation amount of the solar power generation apparatus 2 and the information on the temporal transition of the past power consumption amount of other home appliances. Estimate the time zone when surplus occurs.

  The memory | storage part 124 memorize | stores the result of the time slot estimated by the calculating part 123 as electric power surplus time slot | zone information. The determination unit 126 covers the power consumed during the defrosting operation time of the refrigerator 5 based on the information on the defrosting operation time received by the information receiving unit 121 and the power surplus time zone information stored in the storage unit 124. It is determined whether there is a power surplus time zone that can be used. However, in determining whether or not there is a power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, information on the defrosting operation time received by the information receiving unit 121 and the removal Information on the time limit for completion of the frost operation may be taken into consideration. That is, the operating time information received from the refrigerator 5 may include information on the current defrosting operation time and information on the completion time limit for the current defrosting operation. The completion time limit for the defrosting operation will be described later.

  The determination unit 127 determines the start time of the defrosting operation based on the determination result of the determination unit 126. The information transmission unit 122 transmits information about the start time of the defrosting operation determined by the determination unit 127 to the refrigerator 5.

  Thus, the information processing terminal device 100 stores the estimated time zone result as the power surplus time zone information. Moreover, the information processing terminal device 100 is information on the time to operate as the defrosting operation among the information on the time when the refrigerator 5 is actually operated, and information on the defrosting operation time received from the refrigerator 5 and the power surplus time zone Based on the information, the start time of the defrosting operation as the operation start time of the refrigerator 5 is determined.

  Next, the control processed by the refrigerator 5 is demonstrated using a flowchart. As shown in FIG. 14, it is determined in step S301 whether or not a defrosting operation is necessary. In a conventional general refrigerator-freezer, usually, the integrated value of the time during which the above cooling operation is performed has reached a predetermined value or more, or a predetermined time or more after the last defrosting operation is completed. It is determined that the defrosting operation is necessary when any of the conditions for whether or not it has passed is satisfied. The amount of frost attached to the evaporator of the refrigerator-freezer has been verified in advance by experiments or the like according to the performance of the configuration for operating the refrigeration cycle such as the evaporator. The predetermined integrated value or the predetermined time used for determining whether or not the defrosting operation is necessary is calculated by the calculation means of the refrigerator-freezer based on such a verification result.

  On the other hand, in the refrigerator 5, the determination different from the conventional freezer refrigerator is performed like determination of step S301. In step S301, whether or not the integrated value of the time when the cooling operation of the refrigerator 5 is performed is equal to or greater than a predetermined value (in this case, for example, Ti), or from the end of the previous defrosting operation to the present. In addition, it is determined whether or not a predetermined time (indicated here as Tp, for example) has elapsed. In the refrigerator 5, in order to expand the allowable range for changing or adjusting the time to start the defrosting operation, the integrated value (Ti) of the time when the cooling operation used in the determination of step S301 is performed, and the previous time The predetermined time (Tp) elapsed from the end of the defrosting operation to the present time is set shorter than the integrated value used in the conventional general refrigerator-freezer and the predetermined time, respectively. Has been. The integrated value (Ti) as the threshold value used for the determination in step S301 and the predetermined time (Tp) are stored in the storage unit 552, respectively.

  By doing in this way, compared with the conventional refrigerator-freezer, it is possible to shift the time at which defrosting operation is started in the previous direction in terms of time. Moreover, it is a case where it is determined in advance that the defrosting operation is necessary in advance compared to the conventional refrigerator-freezer, so that the time when the defrosting operation is started extends backward from the time of determination. In addition, it is possible to provide an allowance for the time required to reach a state where more frost than the amount necessary for the defrosting operation is accumulated. Thus, according to determination of step S301 of the refrigerator 5, the time slot | zone which can perform a defrost operation can be extended.

  Note that the predetermined time (Tp) that has passed since the last defrosting operation has ended may be further shortened depending on the result of determination in step S307 described later.

  In step S302, based on the past defrosting operation time including the previous time and the time interval from the end of the previous defrosting operation to the current time, the operation time of the current defrosting operation is the calculation unit 553 (see FIG. 13). Is calculated by At this time, the calculated value of the calculation unit 553 is an estimated value.

  The operation time of the defrosting operation is the time required for the defrosting operation from the start of the defrosting operation to the end thereof. As shown in FIG. 14, the operation time of the defrosting operation as the predetermined operation time is referred to as a defrosting operation time. The current defrosting operation time estimated in step S302 only needs to be estimated based on at least the past defrosting operation time.

  In step S <b> 303, the start restriction time of the defrosting operation and the completion restriction time of the defrosting operation are estimated by calculation of the calculation unit 553. The start time limit for the defrosting operation is estimated based on at least the past defrosting operation time.

  The defrosting operation start time limit means the limit of the start time of the defrosting operation, and the start time of the defrosting operation of the refrigerator 5 is longer than the start time of the defrosting operation of the conventional refrigerator-freezer. This is the time set to extend backwards. For example, when the defrosting operation is started after the start limit time, the cooling operation in the refrigerator 5 may be adversely affected. That is, in order to maintain a state in which no predetermined or specific adverse effect appears in the cooling operation in the refrigerator 5, the defrosting operation must be started at the latest by the start limit time. As described above, the start limit time is a predetermined time set according to the performance of the refrigeration cycle such as the evaporator 524 and the capacity of the refrigerator 5, and the cooling operation of the refrigerator 5 continues well. It is the time set as the limit of the start time of the defrosting operation.

  On the other hand, the defrosting operation completion time limit is calculated by adding the defrosting operation time estimated in step S302 to the estimated start time limit.

  In step S304, the information on the defrosting operation time calculated in step S302 and the information on the completion time limit calculated in step S303 are transmitted to the information processing terminal device 100. In this way, the refrigerator 5 estimates the current defrosting operation time based on the information on the past defrosting operation time among the information on the time when the refrigerator 5 actually operates, and the estimated current time Information on the defrosting operation time is transmitted to the information processing terminal device 100. In addition, the refrigerator 5 transmits information on the time limit for completion of the current defrosting operation to the information processing terminal 100.

  Subsequent to step S304, the start time of the defrosting operation is set in step S305. As will be described later, the start time of the defrosting operation is set by the information processing terminal device 100 (see FIG. 7). In step S306 after step S305, information on the start time of the defrosting operation is transmitted from the information processing terminal device 100, and the information receiving unit 551 of the refrigerator 5 receives the information on the start time. In step S306, information on the power surplus time zone is transmitted from the information processing terminal device 100, and the information receiving unit 551 of the refrigerator 5 receives the information on the power surplus time zone.

  As will be described later, the information processing terminal device 100 can be set to notify the refrigerator 5 that the power surplus time zone does not exist when the power surplus time zone is shorter than the defrosting operation time. As described above, the information on the power surplus time zone may include information for notifying that the power surplus time zone does not exist. Whether or not to include information indicating that the power surplus time zone does not exist in the information on the power surplus time zone is based on the setting and control of the information processing terminal device 100.

  In step S307, it is determined whether or not information for notifying that there is no power surplus time zone is included. When it is determined that the information for notifying that the power surplus time zone does not exist is included, the process proceeds to step S308, and the information for notifying that the power surplus time zone does not exist is included. If it is determined that there is not, the process proceeds to step S309. Note that the determination in step S307 may be whether or not there is a notification that there is no power surplus time zone.

  In step S308, a flag for raising the start time of the next defrosting operation is set. This flag is used for the determination in step S301 as information on the time of the past defrosting operation. When the flag is raised, the timing for starting the defrosting operation is made earlier than in the normal state. In addition, a normal state is a case where there is no power surplus time zone that can cover all of the power consumed during the defrosting operation time of the refrigerator 5, and the flag is not raised. That's it.

  In step S306, based on the control in step S305, information on the start time of the defrosting operation and information on the defrosting operation time are transmitted from the information processing terminal device 100. According to the information on the start time of the defrosting operation and the information on the defrosting operation time determined by the control processed by the information processing terminal device 100, the refrigerator 5 generates power from the solar power generation device 2 (see FIG. 7). The defrosting operation can be performed using the surplus power. However, when the defrosting operation is performed in the defrosting operation time according to the information on the defrosting operation time transmitted from the information processing terminal device 100, there is a possibility that the evaporator 524 is not sufficiently defrosted. There is. Therefore, the adverse effect on the cooling operation can be prevented by advancing the start time of the next defrosting operation in accordance with the control in step S308. In addition, when the start time of the next defrosting operation is advanced, the next defrosting operation time is shortened from the normal time, so that most of the electric power used for the next defrosting operation is reduced to sunlight. This can be covered by the surplus of power generated by the power generation device 2.

  Thus, when there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, the refrigerator 5 starts the start time of the next defrosting operation from the normal state. Also advance.

  In step S309, the standby state of the defrosting operation continues until the start time of the defrosting operation arrives. If it is determined in step S309 that the start time of the defrosting operation has arrived, the process proceeds to step S310. In step S310, the current defrosting operation is started. In addition, as will be described later, when there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, the time zone in which the surplus estimated by the information processing terminal device 100 occurs The defrosting operation of this time is performed in the longest time zone.

  Subsequently, the control for setting the time to start the defrosting operation, that is, the control processed by the information processing terminal device 100 will be described using a flowchart. As shown in FIG. 15, in step S <b> 401, the information reception unit 121 (see FIG. 7) of the information processing terminal device 100 is transmitted from the information transmission unit 555 (see FIG. 13) of the refrigerator 5 to the information processing terminal device 100. Receives information on defrosting operation time. Further, the information receiving unit 121 further receives information on the completion time limit calculated in step S303 (see FIG. 14) from the information transmitting unit 555.

  In step S402, the time transition of the electric power generated by the photovoltaic power generation apparatus 2 from the time point to the completion limit time is estimated with reference to the time point when the defrosting operation time information is transmitted from the refrigerator 5. The information processing terminal device 100 accumulates the temporal transition of the generated power during a certain past period as data by constantly monitoring the generated power of the solar power generation device 2. The average value of the temporal transition of the generated power during a certain past period is calculated by the calculation unit 123 (see FIG. 7) based on the accumulated data, so that the generated power from the present time to the desired operation completion time is calculated. Temporal transition is estimated. An example of the past fixed period is the same as the control for the washer / dryer 900.

  Subsequently, in step S403, based on the time point when the defrosting operation time information and the completion restriction time information are transmitted from the refrigerator 5, the time of power used by other home appliances from that point to the completion restriction time. Transition is estimated. The information processing terminal device 100 accumulates data on the temporal transition of the power used by other home appliances during a certain period in the past by constantly monitoring the power used by other home appliances other than the refrigerator 5. . The average value of the temporal transition of the power used by other home appliances in a certain period in the past is calculated by the calculation unit 123 based on the accumulated data. Temporal transition is estimated. Data on the temporal transition of power used by other home appliances in a certain past period may be distinguished not only for weekdays and holidays but also for each day of the week.

  The “past” in step S402 and step S403 is a time point before the time point when the defrosting operation time information is transmitted from the refrigerator 5. Alternatively, the “past” may be a time point before the time point when the information processing terminal device 100 estimates the power surplus time zone.

  In step S404, the estimated time transition of the generated power of the solar power generation device 2 and the estimated time transition of the power consumption of other home appliances are compared by the calculation unit 123 (see FIG. 7). Thus, a power surplus time zone is estimated as a time zone in which surplus power is generated.

  Subsequent to step S404, in step S405, it is determined whether or not there is a power surplus time zone for the defrosting operation time. While the defrosting operation is being performed in the refrigerator 5, predetermined power is required in a continuous time zone from the start of the defrosting operation to the completion thereof. Therefore, in step S405, it is determined whether or not there is a power surplus time zone that can cover the power for a predetermined time required for the current defrosting operation. If it is determined in step S404 that there is a power surplus time zone that can cover all power for the defrosting operation time, the process proceeds to step S406.

  In step S406, the start time of the defrosting operation is determined. According to the start time determined in step S406, it is possible to achieve from the start to the completion of the defrosting operation in the power surplus time zone in which all the power for the estimated current defrosting operation time can be covered. it can.

  In step S406, when there are a plurality of power surplus time zones that can cover all the power for the defrosting operation time, or a plurality of defrosting operation times can be set in the power surplus time zone. In the case where the estimated power surplus time zone is relatively long, the time in the time zone where the temperature outside the refrigerator 5 is expected to be the lowest in the power surplus time zone is selected. Good.

  When the defrosting operation is performed, the temperature inside the refrigerator 5 increases due to the operation of the heater 527 (see FIG. 12), and thus the cooling operation is performed before and after the defrosting operation. When the temperature outside the refrigerator 5 is relatively low, power consumed in the cooling operation can be suppressed. Thus, when the defrosting operation can be started from the time of the time zone when the temperature outside the refrigerator 5 is low, the power consumed by the refrigerator 5 can be reduced.

  On the other hand, when it is determined in step S405 that there is no power surplus time zone that can cover all power for the defrosting operation time, the process proceeds to step S451 (see FIG. 16).

  The information processing terminal device 100 can be set to notify the refrigerator 5 that the power surplus time zone does not exist when the estimated power surplus time zone is shorter than the defrosting operation time. As described above, the information on the power surplus time zone may include information for notifying that the power surplus time zone does not exist. Whether or not to include information indicating that the power surplus time zone does not exist in the information on the power surplus time zone is based on the setting and control of the information processing terminal device 100.

  In step S451, it is determined whether or not the setting for notifying the refrigerator 5 that there is no power surplus time zone is valid. The user of the information processing terminal device 100 can cause the information processing terminal device 100 to set in advance whether to notify the refrigerator 5 that there is no surplus power time zone. If it is determined as YES in step S451, the process proceeds to step S452, and if it is determined NO, the process proceeds to step S461 (see FIG. 15).

  In step S452, the start time of the defrosting operation and the defrosting operation time are determined based on the time zone in which the power in the power surplus time zone is consumed most efficiently. Note that the defrosting operation time determined in step S452 is a time equal to or shorter than the defrosting operation time calculated in step S302 (see FIG. 14). Thus, when there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, among the time zones in which the surplus estimated by the information processing terminal device 100 occurs This defrosting operation is performed in the longest time zone.

  In step S453, it is determined whether or not the defrosting operation time determined in step S452 is equal to or longer than a reference time in which a minimum function can be performed as the defrosting operation of the refrigerator 5. If it is determined in step S453 that the time is equal to or longer than the reference time, the process proceeds to step S454. If it is determined that the time is less than the reference time, the process proceeds to step S455.

  In step S454, information on the start time of the defrosting operation, information on the defrosting operation time, and information for notifying that there is no power surplus time zone are transmitted from the information processing terminal device 100 to the refrigerator 5. (See FIG. 7).

  On the other hand, in step S455, information on the start time of the defrosting operation among the start time and the defrosting operation time determined by the calculation in step 452 is transmitted to the refrigerator 5. In step S455, the amount of power that is insufficient when the defrosting operation is performed after using only the surplus of the generated power of the solar power generation device 2 is supplemented by the power supplied from the commercial power source 4. As described above, a predetermined signal is transmitted from the information processing terminal device 100 to the power supply switching device 3.

  When the determination unit 126 determines NO in step S453 by the determination unit 126, the determination unit 127 (see FIG. 7) of the information processing terminal device 100 uses the power consumed during the current defrosting operation time and the sun. The power supplied from the commercial power supply 4 and the power generated by the solar power generation apparatus 2 so that the difference power from the surplus power generated by the photovoltaic power generation apparatus 2 is supplied from the commercial power supply 4 to the refrigerator 5 Is transmitted to the information transmission unit 122 to switch the power supply switching device 3. The power supply switching device 3 receives a signal based on the signal from the information transmission unit 122. Thereby, after temporarily using only the surplus of the generated electric power of the solar power generation device 2, an amount of electric power that is insufficient when the defrosting operation is performed can be supplied from the commercial power supply 4 to the refrigerator 5.

  When it is determined in step S451 (see FIG. 16) that the setting for notifying the refrigerator 5 that the power surplus time zone does not exist is not valid, the process proceeds to step S461 (see FIG. 15). In step S461, it is determined whether or not the information processing terminal device 100 is set in advance so that at least the refrigerator 5 among the plurality of home appliances uses power in a time zone in which the electricity rate such as midnight power is relatively low. The If it is determined in step S461 that the information processing terminal device 100 is set so that the refrigerator 5 uses midnight power, the process proceeds to step S462.

  In step S462, it is determined whether or not the power surplus time zone estimated in step S404 includes a midnight time zone with a low electricity bill. If it is determined in step S462 that the power surplus time zone includes the midnight time zone, the process proceeds to step S463.

  In step S463, the start time of the defrosting operation is determined based on the midnight time zone. According to the start time determined in step S463, the defrosting operation is started from midnight.

  On the other hand, when it is determined in step S462 that the power surplus time zone does not include the midnight time zone, or in step S461, the information processing terminal device 100 is set not to use midnight power. If yes, the process proceeds to step S464. In step S464, the start time of the defrosting operation is determined based on the time zone in which the power in the power surplus time zone is consumed most efficiently. According to the start time of the defrosting operation determined in step S463 or step S464, if there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, information processing is performed. The current defrosting operation is performed in the longest time zone among the time zones in which the surplus estimated by the terminal device 100 occurs.

  In step S464, the amount of power that is insufficient when the defrosting operation is performed after using only the surplus of the generated power of the solar power generation device 2 is supplemented by the power supplied from the commercial power source 4. As described above, a predetermined signal is transmitted from the information processing terminal device 100 to the power supply switching device 3. As described above, according to the start time of the defrosting operation determined in step S464, it is possible to cover the shortage from the commercial power supply 4 while using as much power as possible in the power surplus time zone.

  In step S407, information on the start time of the defrosting operation determined in step S406, step S463, or step S464 is transmitted from the information processing terminal device 100 to the refrigerator 5 (see FIG. 13).

  As described above, the power feeding system 1 includes the solar power generation device 2, the washing / drying machine 900, the refrigerator 5, the television 6, the air conditioner 7, the lighting device 8, and the information processing terminal device 100. I have. The washer / dryer 900, the television 6, the air conditioner 7, and the lighting device 8 are examples of other home appliances. The plurality of home appliances are operated by at least electric power generated by the solar power generation device 2. The information processing terminal device 100 is network-connected so that it can communicate with a plurality of home appliances and the solar power generation device 2.

  The information processing terminal device 100 generates surplus in the generated power from the information on the temporal transition of the past power generation amount of the photovoltaic power generation apparatus 2 and the information on the temporal transition of the past power consumption amount of other home appliances. Estimate the time zone. Further, the information processing terminal device 100 stores the estimated time zone result as the power surplus time zone information, and the defrosting operation time received from the refrigerator 5 as information on the time when the refrigerator 5 actually operates as the defrosting operation. Based on the information and the power surplus time zone information, the start time of the defrosting operation of the refrigerator 5 is determined.

  According to the power feeding system 1, the solar power generation device 2 is obtained from the information on the temporal transition of the past power generation amount of the solar power generation device 2 and the information on the temporal transition of the past power consumption amount of other home appliances. Estimate the time zone in which surplus power is generated. Further, the information processing terminal device 100 determines the start time of the defrosting operation as the operation of the refrigerator 5 based on the power surplus time zone information and the information on the defrosting operation time as the operation time information. Thus, according to the power feeding system 1, only the amount of power generated by the solar power generation device 2 at an arbitrary point in time is not used for the determination for starting the defrosting operation of the refrigerator 5, and the refrigerator 5 This defrosting operation can be operated in a time zone where surplus power is generated in the generated power of the solar power generation device 2.

  By doing in this way, the electric power feeding system 1 which can use efficiently the electric power which the solar power generation device 2 generated can be provided.

  The refrigerator 5 is a refrigerator as a predetermined home appliance used in the power feeding system of the solar power generation device 2. The operating time information is information on the defrosting operation time received from the refrigerator 5 as information on the time when the refrigerator 5 actually operates as the defrosting operation, and the operation start time is the start time of the defrosting operation of the refrigerator 5, The information on the defrosting operation time is information on the defrosting operation time estimated by the refrigerator 5 based on the information on the past defrosting operation time.

  According to this configuration, the information processing terminal device 100 receives information on the defrosting operation time estimated by the refrigerator 5 based on the information on the past defrosting operation time. Moreover, the information processing terminal device 100 determines the start time of the defrosting operation of the refrigerator 5 based on the information on the defrosting operation time and the power surplus time zone information. Therefore, according to this configuration, the refrigerator 5 can perform the defrosting operation using the surplus power generated by the solar power generation device 2.

  The refrigerator 5 estimates the defrosting operation start time limit based on the past defrosting operation time information, and further adds the defrosting operation time to the estimated start time limit, thereby completing the defrosting operation completion time limit. Is calculated.

  According to this configuration, the information processing terminal device 100 receives information on the defrosting operation time and information on the completion time of the defrosting operation. Therefore, the refrigerator 5 can start the defrosting operation using the surplus power generated by the solar power generation device 2 by the time when the cooling operation may be adversely affected at the latest. Therefore, according to this configuration, when the defrosting operation is performed using the surplus power generated by the solar power generation device 2, the start time of the defrosting operation is changed backward in time. However, the influence on the cooling operation of the refrigerator 5 can be reduced.

  When there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, the refrigerator 5 has a time zone in which surplus estimated by the information processing terminal device 100 occurs. The current defrosting operation is performed in the longest time zone, and the start time of the next defrosting operation is advanced from the normal state.

  According to this configuration, when there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, the time zone in which the surplus estimated by the information processing terminal device 100 occurs is generated. The current defrosting operation is performed in the longest time zone. Thus, when the defrosting operation is performed in the longest time zone in which surplus occurs, it is expected that a situation where defrosting is insufficient will occur. If the defrosting is insufficient, the cooling operation of the refrigerator 5 may be adversely affected.

  However, according to this configuration, when there is no power surplus time zone that can cover the power consumed during the defrosting operation time of the refrigerator 5, the power is removed in the longest time zone in which surplus occurs. When the frost operation is performed, the start time of the next defrost operation is advanced from the normal state. As described above, the start time of the next defrosting operation is advanced, so that an adverse effect on the cooling operation can be prevented.

  As described above, in step S464 and step S452, the power in the power surplus time zone is consumed most efficiently (in other words, the power generated by the photovoltaic power generator 2 is consumed most). The start time of the frost operation is determined. However, in step S464 and step S452, the start time of the defrosting operation may be determined by selecting the time of the time zone in which the temperature outside the refrigerator 5 is expected to be the lowest. .

  In the refrigerator 5, the defrosting operation described above means that the heater 527 (see FIG. 12) is turned on. However, the defrosting operation may include a cooling operation performed before the heater 527 is turned on and after the heater 527 is turned on.

(Third embodiment)
The third embodiment is a case where the number of predetermined home appliances is plural, that is, 2 as an example. In the third embodiment, the two predetermined home appliances are different types of home appliances. An example of a plurality of predetermined home appliances is a refrigerator 5 as the device A and a washing / drying machine 900 as the device B described below. In the following, control for determining the operation start times of a plurality of predetermined home appliances will be described. Note that the number of the plurality of predetermined home appliances may be three or more. Alternatively, the combination of a plurality of predetermined home appliances is not limited to the washer / dryer 900 and the refrigerator 5, and may be other combinations including other devices. Moreover, the combination of a plurality of predetermined home appliances may include a plurality of home appliances of the same type (for example, home appliances as device A, home appliances as device B, and other home appliances, Each may be a refrigerator 5).

  In 3rd Embodiment, the structure of the washing-drying machine 900 and the structure of the refrigerator 5 are the same as what is shown to 1st Embodiment and 2nd Embodiment, respectively, and description is abbreviate | omitted. In the third embodiment, the configuration of the information processing terminal device 100 includes the configuration shown in the first embodiment and the configuration shown in the second embodiment. Furthermore, in 3rd Embodiment, the control performed between the information processing terminal device 100 and the washing / drying machine 900 and the control performed between the information processing terminal device 100 and the refrigerator 5 are respectively 1st. The control shown in the embodiment and the control shown in the second embodiment are included.

  Below, the case where a some predetermined | prescribed household appliance is comprised with the apparatus A and the apparatus B is demonstrated using FIGS. However, even if the number of the plurality of home appliances is 3 or more and / or the combination of the plurality of predetermined home appliances is another combination other than the refrigerator 5 and the washing / drying machine 900, for example, FIG. ˜20, the information processing terminal device 100 (see FIG. 7) determines the operation start time of each predetermined home appliance.

  As illustrated in FIG. 17, in step S <b> 1001, the information receiving unit 121 (see FIG. 7) of the information processing terminal device 100 receives the operation information of the device A and the operation information of the device B. In the case where the device is the washing / drying machine 900, the operation information includes information on the operation completion desired time and the operation time information of the washing / drying machine 900. When the device is the refrigerator 5, information on the defrosting operation time and the completion time limit are included.

  In step S1002, the temporal transition of the generated power of the photovoltaic power generation apparatus from the present time to the operation completion desired time and the completion limit time of the devices A and B is estimated. In the following, the desired operation completion time and the completion restriction time are collectively referred to as a completion time. Note that the current time refers to, for example, the time when the operation information is transmitted to the information receiving unit 121 (see FIG. 7) of the information processing terminal device 100 (the time when step S1001 is executed).

  In step S1003, the temporal transition of the power consumption of the home appliances excluding the devices A and B from the current time to the completion time is estimated. In step S1004, using the time transition of the generated power estimated by the calculation in step S1002 and the time transition of the used power estimated by the calculation in step S1003, the power surplus time zone (of the solar power generation device 2) Time) when surplus in generated power occurs.

  In step S1005, it is determined whether there is a power surplus time zone in which device A and device B can be operated simultaneously. In other words, the information processing terminal device 100 (see FIG. 7) determines whether there is a power surplus time zone in which a surplus of an amount that can operate the devices A and B simultaneously occurs in the generated power. To do. If YES is determined in step S1005, the process proceeds to step S1006. If NO is determined, the process proceeds to step S1007.

  In step S1005, it is determined whether there is a time zone in which a relatively large surplus power is generated among the power generated by the solar power generation device 2. When there is no time zone in which relatively large surplus power is generated, it is impossible to operate the device A and the device B at the same time, so that the operation period of the device A and the operation period of the device B do not overlap. In addition, it is necessary to determine the operation start time of each device.

  In step S <b> 1006, it is determined whether there is a power surplus time period corresponding to the operation time of the device A and the device B on the assumption that the device A and the device B are operated simultaneously. In other words, the information processing terminal device 100 (see FIG. 7) determines whether the longer operation time of the device A or the device B in the power surplus time zone used for the determination of YES in step S1005 is the time zone. It is determined whether or not the time is less than or equal to. If YES is determined in step S1006, the process proceeds to step S1009. Details of step S1009 will be described later with reference to FIG. On the other hand, if NO is determined in step S1006, the process proceeds to step S1010. Details of step S1010 will be described later with reference to FIG.

  In step S1007, it is determined whether there is a power surplus time zone corresponding to the operating time of the device A and the device B on the assumption that the device A and the device B are not operated simultaneously. In step S1007, it is determined whether or not the total operating time of the devices A and B is equal to or less than the length of the power surplus time zone. If YES is determined in step S1007, the process proceeds to step S1008, and if NO is determined, the process proceeds to step S1010. Note that the determination of NO in step S1007 means that it is impossible to operate both device A and device B using surplus power.

  In step S1008, it is determined whether there is a power surplus time zone in which the device A and the device B can be operated so that the operation period of the device A and the operation period of the device B do not overlap. In other words, in one relatively long power surplus time zone, it is determined whether or not the length of the time zone is longer than the total operating time of the devices A and B. If YES is determined in step S1008, the process proceeds to step S1009, and if NO is determined, the process proceeds to step S1010.

  As described later, after the operation start times of the devices A and B are determined in step S1009 or step S1010, information on the operation start times is transmitted to the devices A and B in step S1011.

  Next, a process for assigning the authority to use surplus power generated by the photovoltaic power generation apparatus 2 to each device according to the priority order (that is, step S1010 shown in FIG. 17) will be described with reference to FIG. First, in step S1101, it is determined whether the priority order of each device is set in advance by the user. If YES is determined in step S1101, the process proceeds to step S1102, and if NO is determined, the process proceeds to step S1103.

  In step S1102, the right to use the surplus power of the photovoltaic power generation apparatus 2 is given to the device A and the device B according to the priority order of each device preset by the user. On the other hand, in step S1103, the right of use is given to the devices A and B according to the priority order corresponding to the characteristics of each device.

  Subsequent to step S1102 or step S1103, in step S1104, it is determined whether or not a power surplus time zone corresponding to the operation time of the device exists for the device to which the usage right is given. Further, the operation start time of this device is determined based on the determination. Specifically, for example, when the device to which the usage right is given is the washing / drying machine 900, the predefined processing in step S110 shown in FIG. 9 (see FIGS. 10 to 11) or the usage right is given. If the device is the refrigerator 5, the predefined process (see FIGS. 15 to 16) in step S305 shown in FIG. 14 is executed in step S1104. In step S1104, the operation start times of the devices A and B are determined so that the operation timing of the device A and the operation timing of the device B do not overlap.

  For example, the defrosting operation of the refrigerator 5 as the device A greatly affects the quality of the cooling operation of the refrigerator 5. On the other hand, since the operation of the washing / drying machine 900 as the device B only needs to be completed by the operation completion time desired by the user, the operation start time of the washing / drying machine 900 is the defrosting of the refrigerator 5. There are no restrictions compared to the start time of the operation. As described above, as the priority order of the usage rights corresponding to the characteristics of each device, for example, in the example of the washing / drying machine 900 and the refrigerator 5, the refrigerator 5 has a higher priority order than the washing / drying machine 900. Yes. Such priority order information corresponding to the characteristics of each device is preliminarily converted into data and stored in the storage unit 124 (see FIG. 7) of the information processing terminal device 100.

  In addition, about the apparatus containing the refrigerator 5 and the washing-drying machine 900, and household appliances different from these refrigerator 5 and the washing-drying machine 900, a priority is set as follows, for example. However, as shown in steps S1101 to S1102 above, the priority order set by the user is preferentially used in a plurality of predetermined home appliances.

  First, an order is preferentially assigned to a device having a time limit, in other words, a device to which a completion time is imposed or a device to which an operation start time is imposed. That is, whether the time limit exists is considered as the first requirement. Second, an order is preferentially assigned to a device that needs to operate continuously, and that consumes a large amount of power and has a long operation time. That is, as a second requirement, whether the power consumption is large and the operation time is long is considered for a device that needs to operate continuously.

  Thirdly, an order is preferentially assigned to devices with a long operation time. Fourth, an order is preferentially assigned to a device with high power consumption. As described above, whether the operation time is long is considered as the third requirement, and whether the power consumption is large is considered as the fourth requirement.

  A device with large power consumption is, for example, an air conditioner 7 (see FIG. 1), a washing / drying machine 900, a rice cooker, an electric water heater, or the like. Devices with low power consumption are, for example, robot cleaners, air cleaners, and the like.

  An apparatus with a short operation time is, for example, an electric pot. Devices with a long operation time are, for example, a washing / drying machine 900, an electric water heater, an air conditioner 7, and the like.

  Examples of devices that need to operate continuously are a washing dryer 900, a rice cooker, and the like. On the other hand, examples of devices that do not need to operate continuously and may be stopped during operation include an electric pot, a defrosting operation of the refrigerator 5, an air conditioner 7, a robot cleaner, and an electric water heater.

  Examples of devices to which the completion time is imposed are a washing / drying machine 900, a rice cooker, and the like. An example of a device to which the operation start time is imposed is an air conditioner 7 or the like.

  Next, the process for determining the operation start times of the devices A and B (that is, step S1009 shown in FIG. 17) will be described using FIG.

  In step S <b> 1201, it is determined whether there are a plurality of power surplus time zones that can cover all the power consumed during the operation time of the devices A and B. For example, it is determined whether there are two or more power surplus time zones that are determined to be YES in steps S1005 and S1006. Alternatively, it is determined whether there are two or more power surplus time zones that are determined to be YES in step S1008. If YES is determined in step S1201, the process proceeds to step S1202, and if NO is determined, the process proceeds to step S1203.

  In step S1202, the operation start times of the devices A and B are adjusted so as to match the earliest time zone or the latest time zone among the plurality of power surplus time zones according to the characteristics of the device A and the characteristics of the device B. Is determined. At this time, the operation start time of the device A or the device B substantially coincides with the starting point of the power surplus time zone during which the devices A and B are operating, or the device A or the device B reaches the end point of the power surplus time zone. Preferably, the operation start times of the devices A and B are determined so that the completion times of

  Depending on the characteristics of each of the devices A and B, the operation start time of any of the devices A and B that need to be completed earlier is the power surplus time period in which the devices A and B are operating. Is determined so that the operation start time of the device substantially coincides with the starting point. On the other hand, among the devices A and B, the operation start time of any device that needs to be completed later is the end of the power surplus time zone, which is the period during which the devices A and B operate, The start times are determined so as to substantially match.

  However, when there is no difference between the characteristics of the devices A and B (that is, both the devices A and B are devices that need to complete operation earlier, or both the devices A and B are delayed). Device A and B start operation based on the difference in power consumption between device A and device B, which is the second requirement above. Time is determined. Alternatively, also in step S1009 executed after passing through steps S1005, S1007, and S1008 shown in FIG. 17, based on the difference in power consumption between device A and device B, devices A and B The operation start time is determined. For example, when both the device A and the device B are devices that need to complete operation early, the operation of the device with large power consumption is started first. When both the device A and the device B are devices that need to complete the operation later, the operation of the device with low power consumption is started first. By doing in this way, more surplus electric power can be left in the electric power surplus time zone which is the period when apparatus A and B operate.

  In step S1203, the operation start times of the devices A and B are determined in the only power surplus time zone. At this time, as in step S1202, the operation start time of the device A or the device B substantially coincides with the starting point of the power surplus time zone, which is the period in which the devices A and B operate, or the power surplus time zone It is preferable that the operation start times of the devices A and B are determined so that the completion time of the device A or the device B substantially coincides with the end point.

  In addition, by operating the device A and the device B in the earliest time zone or the latest time zone, for example, another predetermined device that is not included in the plurality of predetermined home appliances or the operation start time is redetermined. The device A or device B can have a relatively long power surplus time period. In addition, in the power surplus time zone in which the devices A and B are operating, by determining the operation start time of the device A and the operation start time of the device B at the earliest time or the latest time, for example, a plurality of times A relatively long power surplus time zone can be left in another predetermined device that is not included in the predetermined home appliance, or in the device A or the device B whose operation start time is determined again.

  Specifically, for the washing / drying machine 900, the time closest to the operation completion desired time is, for example, the end point of the latest time zone. In view of this, the operation start time of the washer / dryer 900 is preferably determined so that the operation completion time substantially coincides with the end point of the latest time zone. The requirement for determining the operation start time according to the characteristics of the device is preferably preliminarily converted into data and stored in the storage unit 124 (see FIG. 7) of the information processing terminal device 100.

  By the way, the time which determines the time which starts the driving | operation of several household appliances may not be simultaneous about all the household appliances, for example, may differ for every household appliances. Therefore, the operation start time of one predetermined home appliance is first so that one predetermined home appliance among a plurality of predetermined home appliances is operated in a time zone in which surplus power is generated in the solar power generation device 2. In order to be able to efficiently use the surplus of the generated power of the photovoltaic power generation apparatus 2 by another predetermined household electrical appliance different from the one predetermined household electrical appliance. It is preferable that the operation start time of the predetermined home appliance is determined.

  However, when the surplus of the generated power of the solar power generation device 2 is insufficient or the time during which the surplus power is generated in the solar power generation device 2 is relatively short, another operation start time is determined later. There arises a situation in which home appliances cannot use the surplus power generated by the solar power generation device. On the other hand, the operation start time can be changed before the operation of the home appliance whose operation start time is determined first is started. Therefore, when the operation start time of another predetermined household electrical appliance is determined after the operation start time of one predetermined household electrical appliance is determined, the operation time of the determined one predetermined household electrical appliance is changed. By doing, it can be made to drive | operate so that the surplus part of the generated electric power of the solar power generation device 2 may be utilized by both one predetermined household appliances and another predetermined household appliances.

  Hereinafter, a process for determining the operation start time of the second predetermined home appliance in the state where the operation start time of the first predetermined home appliance has already been determined will be described using FIG.

  Note that the first predetermined home appliance is a device whose operation start time has been determined first among predetermined home appliances. The second predetermined home appliance is a device in which the operation start time is determined after the first predetermined home appliance in which the operation start time is determined first among the predetermined home appliances. . In the following, an example in which the device A is a first predetermined household electrical appliance and the device B is a second predetermined household electrical appliance will be described.

  In step S1301, the operation start time of the device A is determined. At the time when step S1301 is executed, the device A has not reached the operation start time. Thus, for example, steps S1302 to S1305 are executed in a state where the operation start time of the device A has already been determined and the device A has not reached the operation start time. In step S1302, the information receiving unit 121 (see FIG. 7) of the information processing terminal device 100 receives the operation information of the device B.

  Subsequently, in step S1303, whether there is a surplus power time zone that can cover the amount of power consumed during the predetermined operating time of the device B without changing the operation start time of the device A that has already been determined. Whether it is determined. If YES is determined in step S1303, the process proceeds to step S1304. If NO is determined, the process proceeds to step S1002 (see FIG. 17).

  In step S1304, the operation start time of device B is determined so that device B operates in the corresponding power surplus time zone. Note that the control executed in step S1304 is the same as the control executed for device B in step S1009 (see FIG. 17). That is, step S1304 is executed according to step S1009 (see FIG. 17), that is, the flowchart shown in FIG.

  Subsequent to step S1304, information about the operation start time is transmitted to device B in step S1305. In step S1305, information on the operation start time that has not been changed may be transmitted to the device A again.

  If NO is determined in step S1303, the process proceeds to step S1002 (see FIG. 17). In the steps after step S1002 shown in FIG. 17, for example, the operation start time of the device A is determined again based on the operation information of the device A transmitted in the past. At the same time, the operation start time of the device B is determined in steps after step S1002 based on the operation information of the device B transmitted in step S1302 (see FIG. 20). The device B whose operation start time has been determined in the steps after step S1002 is notified of the operation start time determined in step S1009.
