Description

  The present invention relates to an electric device, an electric device control method, an electric device control program, and an electric device control apparatus that change an operation start time designated by a user.

  Home appliances such as rice cookers and air conditioners have a timer reservation operation function. The timer reservation operation function has the following two types.

  The first is a timer reservation operation in which a user sets a desired time and the home appliance starts driving when the set time is reached. The second is a timer reservation operation in which the home appliance ends its operation when the time set by the user is reached, or the home appliance completes a predetermined operation at the set time.

  As an example of the timer reservation operation for setting the first operation start time, there is a timer reservation operation of a dishwasher and a garbage disposal machine. If the user sets the operation start time, for example, at 23:00 so that the user can drive in the night time zone (23: 00-7pm) when the power rate is low, and the user goes to bed before 23:00, The dishwasher and garbage processor automatically start operation.

  As an example of the timer reservation operation for setting the second operation end time, there is a timer reservation operation of the rice cooker and the washing / drying machine. In the timer reservation operation of the rice cooker, the cooking end time is set so that rice is cooked according to the meal time. For example, the user sets the operation end time of the rice cooker in accordance with the return time or the wake-up time.

  In addition, the timer reservation operation of the washing / drying machine is set in advance so that the time at which washing of clothes is finished or the time at which drying of clothes is finished is a time convenient for the user. For example, the user sets the operation end time of the washing / drying machine in accordance with the return time or the wake-up time.

  As described above, assuming that the home appliance is used, the timer reservation operation in which the home appliance starts to operate when the set time comes, and the home appliance ends the operation at the time set by the user, or The timer reservation operation in which the home appliance completes a predetermined operation at the set time is properly used.

  Moreover, there exists household appliances provided with both the timer reservation driving | running which a household appliance starts a driving | operation, and the timer reservation driving | running which a household appliance ends a driving | operation like an air conditioner. The user sets a time at which the operation of the air conditioner is terminated at the time of going to bed, and sets a time at which the operation of the air conditioner is started at the time of waking up. Depending on the air conditioner, there is a home appliance with a timer reservation operation that starts the operation early so that the room temperature set at the reserved time is reached.

  By the way, the timer reservation driving | operation WHEREIN: There exists the driving | running method which makes an electric power charge cheap by giving the width | variety to the reservation time and driving an household appliance in the time zone when the electric power charge is cheap within the time width.

  For example, when home appliances store information on power charges according to time zones, the user sets a desired operation start time (or desired operation end time), and operates the home appliances in the vicinity of the set time The operation start time is calculated such that the electricity bill charged for is the lowest, and the operation is started when the operation start time is reached.

  For example, in Patent Document 1, the latest time at which the user wants to end the operation of the device is set as the latest desired end time, and the device does not exceed the energy consumption upper limit frame before reaching the latest desired end time. An energy supply and demand adjustment system for determining the operation schedule is disclosed. Note that Patent Document 1 describes a washing machine, a clothes dryer, and a dishwasher as devices.

JP 2007-336655 A

  In Patent Literature 1, the latest time when the user desires to end the operation of the device is set as the latest desired end time (hereinafter referred to as a desired operation end time).

  Here, if the user sets the desired driving end time to end driving by 10 am, for example, the driving end time will be a little late, but if the user ends driving by 10:10 am, the electricity bill will be cheaper. In this case, the user cannot be informed that there is such an operating time setting. That is, it is not possible to propose an operation end time that is not assumed by the user. In addition, there is a problem that it is not known how much the operation end time may be delayed from the desired operation end time in order to reduce the electricity bill.

  Also, as described in the timer reservation operation described above, it is more convenient to set the operation start time instead of the operation end time depending on the device, and there are usually home appliances that are designed to set the operation start time. . For example, in a dishwasher and a garbage disposal machine, a timer reservation operation is performed assuming a life scene in which an operation start time is set before going to bed and the user operates while sleeping.

  Therefore, when timer reservation operation of various home appliances is performed with a common remote controller or control device, the operation end time desired by the user is input and set (Patent Document 1), and the operation start time desired by the user There are two cases where the setting is made by inputting.

  In that case, the user operates the first step for setting the desired time, the second step for setting whether the set desired time is the operation start time or the operation end time, and the operation by the set desired time. It is necessary to perform a third step of setting whether to start (or end) the operation after the set desired time. In other words, in the timer reservation of the current washing and drying machine, the user only needs to set the operation end time, but in the timer reservation operation that reserves the time for reducing the electricity bill, the user needs three steps. Become. There are fears that a user does not use a troublesome function with many setting operations.

  FIG. 25A to FIG. 25D are diagrams illustrating an example of an operation pattern with respect to a desired time input by a user. FIG. 25A is a diagram illustrating an operation pattern when the operation of the home appliance starts before the desired time, and FIG. 25B illustrates an operation pattern when the operation of the home appliance starts after the desired time. FIG. 25C is a diagram illustrating an operation pattern when the operation of the home appliance is completed by the desired time, and FIG. 25D is a diagram illustrating the operation of the home appliance after the desired time. It is a figure which shows the driving | running pattern in the case of complete | finishing.

  The settings of the first to third steps must be performed by the user assuming four driving patterns as shown in FIGS. 25 (A) to 25 (D). However, it is not easy for the user to set the desired operation start time or the desired operation end time by comparing the operation time of the home appliance and the life scene of the user.

  For example, when setting the reserved operation of the washing / drying machine, the user is empirically used to set the operation end time, so it may be unthinkable to set the operation start time. Then, even if the home appliance has a function that can set the operation start time and the operation end time of the four operation patterns in FIGS. 25A to 25D, the user can perform the operations shown in FIGS. Only the operation end time of the two operation patterns of 25 (D) can be set.

  The home appliance 1 is, for example, a washing / drying machine, a rice cooker, an electric water heater, a dishwasher, a clothes dryer, an air conditioner, an electromagnetic cooker (IH), and a garbage disposal machine.

  The driving information acquisition unit 11 includes, for example, a switch for operating the home appliance 1 by a user, a keyboard, or a touch panel. The driving information acquisition unit 11 operates the driving conditions for driving the home appliance 1 and the desired operation of the home appliance 1 desired by the user. The desired operation time indicating the start time or the desired operation end time is acquired. Note that the operating conditions are, for example, operation modes such as a standard washing mode, a firm washing mode, a washing mode, a dehydration mode, and a drying mode if the home appliance 1 is a washing / drying machine. Moreover, you may acquire the weight of the clothes to wash from a weight sensor. The driving information acquisition unit 11 outputs the acquired driving conditions to the driving information reading unit 13 and outputs the acquired desired driving time to the driving time calculation unit 16.

  The driving information storage unit 12 stores driving period information indicating a period required for driving the home electric appliance 1 and electric energy information indicating an electric power required for driving the electric home appliance 1 in association with the driving conditions. The driving information storage unit 12 stores driving period information and electric energy information associated with the driving conditions in advance, but the present invention is not particularly limited thereto, and driving period information associated with the driving conditions and You may acquire electric energy information from an external server via the communication part 14 mentioned later.

  The driving information reading unit 13 includes driving period information corresponding to the driving conditions acquired by the driving information acquiring unit 11 and power amount information corresponding to the driving conditions acquired by the driving information acquiring unit 11. Read from.

  The communication unit 14 connects to an external server via a network and transmits / receives information.

  The power rate information acquisition unit 15 acquires power rate information indicating a power rate that changes with time via the communication unit 14. The power rate information is provided from, for example, an electric power company. For example, the power charge information acquisition unit 15 acquires the power charge information of the day on the previous day and stores it in the internal memory. The power rate information represents a change in power rate per 1 kWh for 24 hours. The electric power charge fluctuates according to time, for example, every hour. This is because electricity supply sources such as solar cells and fuel cells are installed in homes with home appliances, and electricity supply systems to homes change drastically due to the installation of storage batteries. It reflects the changing real-time pricing.

  Real-time pricing generally indicates power rate information notified from an electric power company in advance. Real-time pricing is created not only from information on electricity charges from electric power companies, but also from past results of household appliances such as power supply sources and storage batteries, information on purchased electricity charges, and information on electricity sales. In some cases, the power rate information is displayed.

  As described above, the power rate information is applied only to a certain home created not only from the power rate information from the power company but also from the past performance of the device operation information, the power purchase fee information and the power sale fee information.

  The operation time calculation unit 16 includes the desired operation time acquired by the operation information acquisition unit 11, the power rate information acquired by the power rate information acquisition unit 15, and the operation period information read by the operation information reading unit 13. Based on the above, for each of a plurality of operation patterns of the household electrical appliance 1 defined according to the desired operation time, an operation start time at which the power rate is equal to or lower than a predetermined rate is calculated. Here, the predetermined fee is an amount that the user may pay for using the home appliance 1 once. For example, normal power when the home appliance 1 is operated under conditions that do not reflect real-time pricing. It is a charge.

  Note that the operation time calculation unit 16 may calculate only the operation end time instead of calculating only the operation start time, or may calculate both the operation start time and the operation end time.

  For example, the operation time calculation unit 16 determines a predetermined value from the first operation start time when the power charge is equal to or lower than a predetermined charge in the first operation pattern in which the operation of the home appliance 1 is started by the desired operation time, and the desired operation time. At least a second operation start time at which the power charge is equal to or lower than a predetermined charge in a second operation pattern that is within the time and starts operation of the home appliance 1 after the desired operation time is calculated.

  In addition, the operation time calculation unit 16 performs a predetermined operation from the third operation start time when the power charge is equal to or lower than the predetermined charge in the third operation pattern in which the operation of the home appliance 1 is completed by the desired operation time, and the predetermined operation time. At least a fourth operation start time at which the power charge is equal to or lower than a predetermined charge in a fourth operation pattern that is within the time and ends the operation of the home appliance 1 after the desired operation time is calculated. The predetermined time will be described later.

  In the present embodiment, the “first operation pattern” and the “first operation start time” correspond to the “third operation pattern” and the “third operation start time” in the claims. , “Second operation pattern” and “second operation start time” correspond to “fourth operation pattern” and “fourth operation start time” in the claims, and “third operation pattern” ”And“ third operation start time ”correspond to“ first operation pattern ”and“ first operation start time ”in the claims, and“ fourth operation pattern ”and“ fourth operation start time ”. The “start time” corresponds to the “second operation pattern” and the “second operation start time” in the claims. The same applies to other embodiments.

  The electricity bill calculation unit 17 includes a plurality of operation start times (first to fourth operation start times) calculated by the operation time calculation unit 16, power rate information acquired by the power rate information acquisition unit 15, Based on the driving period information read by the information reading unit 13 and the electric energy information read by the driving information reading unit 13, a plurality of driving start times (first to first times) calculated by the driving time calculating unit 16. The electricity bill charged when the home appliance 1 is driven at each of the fourth driving start times) is calculated.

  The rank assignment unit 18 assigns ranks to a plurality of operation start times (first to fourth operation start times) in the order of cheaper electricity bills calculated by the electricity bill calculation unit 17.

  The notification unit 19 includes, for example, a liquid crystal display unit, and notifies the user of a plurality of operation start times (first to fourth operation start times) calculated by the operation time calculation unit 16. In addition, the notification unit 19 notifies a plurality of driving start times together with the ranks given by the rank assignment unit 18.

  In addition, in this Embodiment 1, the alerting | reporting part 19 is comprised by the display part, However, This invention is not specifically limited to this, The alerting | reporting part 19 is the audio | voice output part which outputs an audio | voice, and the household appliances 1 An output unit for outputting to a display device connected to the display device may be included.

  The operation time calculation unit 16 may calculate first to fourth operation end times corresponding to the first to fourth operation start times, and the notification unit calculates the operation time calculation unit 16. The user may be notified of the first to fourth operation end times.

  The operation time selection accepting unit 20 accepts selection of the operation start time desired by the user from among the plurality of operation start times notified by the notification unit 19.

  The operation time storage unit 21 stores the operation start time received by the operation time selection reception unit 20. The clock unit 22 measures time. The operation control unit 23 refers to the clock unit 22 and controls the operation of the home appliance 1 based on the operation start time stored in the operation time storage unit 21. That is, the operation control unit 23 outputs a start signal when the current time reaches the operation start time stored in the operation time storage unit 21, and controls the home appliance 1 to start operation.

  Next, the operation of the home appliance in the first embodiment will be described.

  FIG. 2 is a flowchart for illustrating the operation of the household electrical appliance according to the first embodiment.

  First, in step S1, the driving information acquisition unit 11 acquires a driving condition for driving the home appliance 1 and a desired driving time indicating a desired driving start time or a desired driving end time of the home appliance 1 desired by the user. To do. The driving information acquisition unit 11 receives an input of a driving condition for driving the home appliance 1 and a desired driving time indicating a desired driving start time or a desired driving end time of the home appliance 1 desired by the user.

  For example, the user inputs a desired operation start time or a desired operation end time of the home appliance 1. The user inputs an actual desired operation start time or desired operation end time such as “18:00”. Alternatively, the user inputs how many hours from the current time, such as “after 8 hours”, the operation starts or ends. Note that the user may input the desired operation start time and the desired operation end time without particular awareness. Further, as in the prior art, a step for setting whether the desired set input time is an operation start time or an operation end time, whether to start (or end) the operation by the set desired time, and set There is no need to set whether to start (or end) the operation after the desired time.

  In addition, the user inputs operating conditions for driving the home appliance 1. For example, if the household electrical appliance 1 is a washing / drying machine, the driving information acquisition unit 11 acquires a washing course (such as a standard course, an energy saving course, and a short-time course) selected by the user as driving conditions.

  In particular, if the household electrical appliance 1 is a washing / drying machine, a plurality of steps (for example, a washing step, a dehydration step, a drying step, etc.) are sequentially performed during the operation, and thus the operation conditions are complicated. The driving information acquisition unit 11 acquires the washing course, the weight of the laundry clothes, and the sensor results such as the water temperature and the outside temperature as driving conditions.

  Next, in step S <b> 2, the driving information reading unit 13 includes driving period information corresponding to the driving condition acquired by the driving information acquiring unit 11 and electric energy information corresponding to the driving condition acquired by the driving information acquiring unit 11. Are read from the driving information storage unit 12. The driving information reading unit 13 outputs the read driving period information to the driving time calculation unit 16. In addition, the operation information reading unit 13 outputs the read operation period information and power amount information to the electricity cost calculation unit 17.

  Next, in step S <b> 3, the power rate information acquisition unit 15 acquires power rate information indicating a power rate that changes with time via the communication unit 14. The power charge information acquisition unit 15 accesses an external server operated by the power company via the communication unit 14 and acquires power charge information from the external server. However, the present invention is not particularly limited to this, The power rate information acquisition unit 15 may read out power rate information stored in advance in an internal memory. The power rate information acquisition unit 15 outputs the acquired power rate information to the operation time calculation unit 16 and the electricity cost calculation unit 17.

  Next, in step S <b> 4, the driving time calculation unit 16 reads the desired driving time acquired by the driving information acquisition unit 11, the power rate information acquired by the power rate information acquisition unit 15, and the driving information reading unit 13. Based on the issued driving period information and the electric energy information read out by the driving information reading unit 13, the household electric appliance 1 is set for each of a plurality of driving patterns of the household electric appliance 1 defined according to the desired driving time. An operation start time calculation process for calculating an operation start time at which the electricity bill charged when the vehicle is operated is the lowest is executed.

  Here, the operation start time calculation process in step S4 of FIG. 2 will be described. FIG. 3 is a flowchart for explaining the operation start time calculation process in step S4 of FIG. FIG. 4A is a schematic diagram showing a first operation pattern for starting the operation of the home electric appliance by the desired operation start time, and FIG. 4B is within a predetermined time from the desired operation start time. FIG. 4C is a schematic diagram showing a second operation pattern in which the operation of the home appliance is started after the desired operation start time, and FIG. 4C is a diagram illustrating the end of the operation of the home appliance by the desired operation end time. 4D is a schematic diagram illustrating a driving pattern of No. 3, and FIG. 4D illustrates a fourth driving pattern that is within a predetermined time from the desired driving end time and that ends the operation of the home appliance after the desired driving end time. It is a schematic diagram shown.

  First, in step S <b> 21, the operation time calculation unit 16 starts the operation of the home appliance 1 in a time zone in which the power rate is the cheapest in the first operation pattern in which the operation of the home appliance 1 is started before the desired operation start time. A first operation start time calculation process for calculating a first operation start time for the purpose is executed. In this case, as shown in FIG. 4 (A), the first operation is performed so that the operation of the household electrical appliance 1 is started in the time zone from the current time to the desired operation time and at the lowest power rate. A start time is calculated. The first operation start time calculation process will be described later.

  Next, in step S <b> 22, the driving time calculation unit 16 is within a predetermined time from the desired driving start time, and in the second driving pattern in which the driving of the home appliance 1 is started after the desired driving start time, The second operation start time calculating process for calculating the second operation start time for starting the operation of the home appliance 1 in the cheapest time zone is executed. In this case, as shown in FIG. 4B, the operation of the home appliance 1 is started within a predetermined time from the desired operation time, after the desired operation time, and in the time zone with the lowest power rate. Thus, the second operation start time is calculated. The second operation start time calculation process will be described later.

  Next, in step S <b> 23, the operation time calculation unit 16 starts the operation of the home appliance 1 in the time zone in which the power rate is the cheapest in the third operation pattern in which the operation of the home appliance 1 is ended by the desired operation end time. A third operation start time calculation process for calculating a third operation start time for performing is performed. In this case, as shown in FIG. 4C, the third operation is performed so that the operation of the household electrical appliance 1 is terminated in the time period from the current time to the desired operation time and at the lowest power rate. A start time is calculated. The third operation start time calculation process will be described later.

  Next, in step S24, the driving time calculation unit 16 has a power charge in a fourth driving pattern that is within a predetermined time from the desired driving end time and ends the operation of the home appliance 1 after the desired driving end time. 4th operation start time calculation processing which calculates the 4th operation start time for starting operation of household appliances 1 in the cheapest time zone is performed. In this case, as shown in FIG. 4D, the operation of the home appliance 1 is terminated within a predetermined time from the desired operation time, after the desired operation time, and in the time zone with the lowest power rate. Thus, the fourth operation start time is calculated. The fourth operation start time calculation process will be described later.

  Next, in step S25, the operation time calculation unit 16 determines whether the calculated first to fourth operation start times can be executed, and can execute the operation start time determined to be impossible. An operation start time adjustment process is performed to make adjustments as follows. The operation start time adjustment process will be described later.

  Here, the first operation start time calculation process in step S21 of FIG. 3 will be described. FIG. 5 is a flowchart for explaining the first operation start time calculation process in step S21 of FIG.

  First, in step S <b> 31, the operation time calculation unit 16 searches for a time zone with the lowest power rate between the current time and the time obtained by adding the operation period to the desired operation time. The cheapest time zone for the power rate here is the lowest time zone for the power rate between the current time and the time when the operation period is added to the desired operation time. Not the cheapest time zone.

  Next, in step S <b> 32, the operation time calculation unit 16 determines whether or not there is a time zone with the lowest power rate between the current time and the time obtained by adding the operation period to the desired operation time. Here, when it is determined that there is a time zone with the lowest power rate between the current time and the time obtained by adding the operation period to the desired operation time (YES in step S32), the operation time is calculated in step S33. The unit 16 determines the end of the time zone with the lowest power rate as the operation end time.

  Next, in step S34, the operation time calculation unit 16 calculates the first operation start time by going back the operation period from the determined operation end time.

  On the other hand, when it is determined that there is no cheapest time zone between the current time and the desired operation time plus the operation period, that is, the operation period is set from the current time to the desired operation time. If the power rate does not change before the added time (NO in step S32), in step S35, the operation time calculation unit 16 determines the desired operation time as the first operation start time.

  FIG. 6 is a schematic diagram for explaining the first operation start time calculation process. In FIG. 6, the current time is 14:00, the operation period of the home appliance 1 is 1 hour, and the desired operation time is 16:30. In addition, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and the time from 23:00 to 2 o'clock The electricity charge for the band is 8 yen / kWh.

  First, the operation time calculation unit 16 operates from 14:00 (current time) to 17:30 (the desired operation time (16:30) plus the operation period (1 hour)), Find the cheapest time of the day. In the time zone from 14:00 to 17:30, the power rate in the time zone from 14:00 to 17:00 is 28 yen / kWh, and the power rate in the time zone from 17:00 to 17:30 21 yen / kWh. Therefore, the operation time calculation unit 16 extracts the time zone from 17:00 to 17:30 when the power rate is 21 yen / kWh as the cheapest time zone of the power rate.

  Next, the operation time calculation unit 16 determines 17:30, which is the end of the time zone with the lowest power rate, as the operation end time.

  Next, the operation time calculation unit 16 calculates 16:30, which is one hour later than the operation period, from 17:30 as the operation end time, as the first operation start time. In this way, the first operation start time is determined at 16:30, and the household electrical appliance 1 is operated from 16:30 to 17:30. And when the electric power consumption of 1 hour of the household appliances 1 is 1 kWh, the charged electricity bill will be (28 yen + 21 yen) /2=24.5 yen.

  In FIG. 6, when the desired operation time is, for example, 15:00, the range searched by the operation time calculation unit 16 is from 14:00 to 16:00 (the operation period (1 hour) is added to the desired operation time (15:00)). Time). In this case, the power charge in the time zone from 14:00 to 16:00 is a uniform 28 yen / kWh. Therefore, the operation time calculation unit 16 determines that there is no time zone with the lowest power rate. As a result, the operation time calculation unit 16 determines 15:00, which is the desired operation time, as the first operation start time. At this time, if the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 28 yen.

  In FIG. 6, when the desired operation time is, for example, 24:00, the range searched by the operation time calculation unit 16 is 14:00 to 1 o'clock (the operation period (1 hour) is added to the desired operation time (24:00)). Time). In this case, in the time zone from 14:00 to 1 o'clock, the time zone with the lowest power charge is from 23:00 to 1 o'clock. Therefore, the operation time calculation unit 16 extracts the time zone from 23:00 to 1 o'clock where the power rate is 8 yen / kWh as the cheapest time zone of the power rate. As a result, the operation time calculation unit 16 determines 1 o'clock, which is the end of the time zone with the lowest power rate, as the operation end time, and calculates 24:00 as the first operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIGS. 5 and 6, the description has been made so that only the cheapest time zone of the electric power charge is searched from the current time to the time obtained by adding the operation period to the desired operation time. Alternatively, a plurality of first operation start times may be calculated by searching for the second lowest time zone. Further, the operation start time may be calculated every time the power rate changes from the current time to the time obtained by adding the operation period to the desired operation time.

  Next, the second operation start time calculation process in step S22 of FIG. 3 will be described. FIG. 7 is a flowchart for explaining the second operation start time calculation process in step S22 of FIG.

  First, in step S41, the operation time calculation unit 16 searches for the time zone with the lowest power rate from the desired operation time to the time obtained by adding the operation period and the allowable period to the desired operation time. Here, the cheapest time zone of the electricity rate is the cheapest time zone of the electricity rate between the current time and the time obtained by adding the operation period and the allowable period to the desired operation time. It's not the cheapest time of the electricity bill.

  The allowable period represents a period that is allowed even if the desired operation start time or the desired operation end time is earlier or later, and is set to 5 hours in the present embodiment, for example. Further, when the time from the current time to the desired operation time is long, it may be limited within the allowable period retroactively from the desired operation time. Although the allowable period is stored in advance, the user can set an arbitrary period. The permissible period may be different for each home appliance and stored, or the permissible period may be different according to the desired operation time or the operation time of the device.

  Next, in step S <b> 42, the operation time calculation unit 16 determines whether or not there is a time zone with the lowest power rate between the desired operation time and the time obtained by adding the operation period and the allowable period to the desired operation time. Determine whether. Here, when it is determined that there is a time zone with the cheapest power rate between the desired operation time and the time obtained by adding the operation period and the allowable period to the desired operation time (YES in step S42), step S43 The operation time calculation unit 16 determines whether or not the desired operation time is included in the time zone with the lowest power charge.

  If it is determined that the desired operation time is not included in the time zone with the lowest power rate (NO in step S43), in step S44, the operation time calculation unit 16 sets the second end of the time zone with the lowest power rate as the second end. The operation start time is determined.

  On the other hand, if it is determined that there is no cheapest time zone between the desired operation time and the time obtained by adding the operation period and the allowable period to the desired operation time, that is, the desired operation time It is determined that the power rate does not change before the time obtained by adding the operation period and the allowable period to the operation time (NO in step S42), or the desired operation time is included in the cheapest time zone of the power rate If so (YES in step S43), in step S45, the operation time calculation unit 16 determines the desired operation time as the second operation start time.

  FIG. 8 is a schematic diagram for explaining the second operation start time calculation process. In FIG. 8, the current time is 14:00, the operation period of the home appliance 1 is 1 hour, the allowable period is 5 hours, and the desired operation time is 16:30. In addition, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and the time from 23:00 to 2 o'clock The electricity charge for the band is 8 yen / kWh.

  First, the operation time calculation unit 16 calculates an operation period (1 hour) and an allowable period (5 hours) from 16:30 (desired operation time) to 22:30 (desired operation time (16:30)). The time zone with the lowest power rate is searched until the time (added time). In the time zone from 16:30 to 22:30, the power charge in the time zone from 16:30 to 17:00 is 28 yen / kWh, and the power charge in the time zone from 17:00 to 22:30 However, it is 21 yen / kWh. Therefore, the operation time calculation unit 16 extracts the time zone from 17:00 to 22:30 when the power rate is 21 yen / kWh as the cheapest time zone.

  Next, the operation time calculation unit 16 determines whether or not the desired operation time is included in the time zone with the lowest power charge. In the example of FIG. 8, the operation time calculation unit 16 determines that the desired operation time (16:30) is not included in the cheapest time zone (17:00 to 22:30), and the power rate 17:00, which is the start of the cheapest time zone, is determined as the second operation start time. In this way, the second operation start time is determined at 17:00, and the home electric appliance 1 is operated from 17:00 to 18:00. And when the electric power consumption per hour of the household appliances 1 is 1 kWh, the charged electricity bill is 21 yen.

  In FIG. 8, when the desired operation time is, for example, 20:00, the range searched by the operation time calculation unit 16 is a range from 20:00 to 2 o'clock. In this case, the power rate in the time zone from 20:00 to 23:00 is 21 yen / kWh, and the power rate in the time zone from 23:00 to 2 o'clock is 8 yen / kWh. Therefore, the operation time calculation unit 16 determines that the desired operation time (20 o'clock) is not included in the cheapest time zone (23:00 to 2 o'clock), and at the start of the cheapest time zone A certain 23:00 is determined as the second operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIG. 8, when the allowable period is 12 hours, for example, the range searched by the operation time calculation unit 16 is a range from 16:30 to 5:30. In this case, the power charge in the time zone from 16:30 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and from 5 pm The power charge for the time period up to 30 minutes is 8 yen / kWh. Therefore, the operation time calculation unit 16 determines that the desired operation time (16:30) is not included in the cheapest time zone (23:00 to 5:30) of the power rate, and the time when the power rate is the lowest 23:00, which is the beginning of the belt, is determined as the second operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIG. 7 and FIG. 8 described above, the description is made so that only the cheapest time zone in which the power rate is the cheapest is searched from the desired operation time to the time obtained by adding the operation period and the allowable period to the desired operation time. However, the present invention is not limited to this, and the second cheapest time zone may also be searched to calculate a plurality of second operation start times. Further, the operation start time may be calculated every time the power rate changes from the desired operation time to the time obtained by adding the operation period and the allowable period to the desired operation time.

  Next, the third operation start time calculation process in step S23 of FIG. 3 will be described. FIG. 9 is a flowchart for explaining the third operation start time calculation process in step S23 of FIG.

  First, in step S51, the operation time calculation unit 16 searches for a time zone with the lowest power rate between the current time and the desired operation time. Here, the cheapest time zone of the power rate here is the cheapest time zone of the power rate between the current time and the desired operation time, and is not the cheapest time zone of the power rate within the day.

  Next, in step S52, the operation time calculation unit 16 determines whether or not there is a time zone with the lowest power rate between the current time and the desired operation time. Here, when it is determined that there is a time zone with the cheapest power charge between the current time and the desired operation time (YES in step S52), in step S53, the operation time calculation unit 16 sets the lowest power charge. The end of the cheap time zone is determined as the operation end time.

  On the other hand, if it is determined that there is no cheapest time zone between the current time and the desired operation time, that is, the power rate does not change between the current time and the desired operation time (step In step S54, the operation time calculation unit 16 determines the desired operation time as the operation end time.

  Next, in step S55, the operation time calculation unit 16 calculates a third operation start time by going back the operation period from the determined operation end time.

  FIG. 10 is a schematic diagram for explaining the third operation start time calculation process. In FIG. 10, the current time is 14:00, the operation period of the home appliance 1 is 1 hour, and the desired operation time is 16:30. In addition, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and the time from 23:00 to 2 o'clock The electricity charge for the band is 8 yen / kWh.

  First, the operation time calculation unit 16 searches for a time zone with the lowest power rate between 14:00 (current time) and 16:30 (desired operation time). The power charge in the time zone from 14:00 to 16:30 is a uniform 28 yen / kWh. Therefore, the operation time calculation unit 16 determines that there is no time zone with the lowest power rate.

  Next, the operation time calculation unit 16 determines 16:30, which is the desired operation time, as the operation end time.

  Next, the operation time calculation unit 16 calculates 15:30, which is one hour later than the operation period from 16:30 as the operation end time, as the third operation start time. In this way, the third operation start time is determined at 15:30, and the household electrical appliance 1 is operated from 15:30 to 16:30. At this time, if the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 28 yen.

  In FIG. 10, when the desired operation time is, for example, 19:00, the range searched by the operation time calculation unit 16 is a range from 14:00 to 19:00. In this case, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, and the power charge in the time zone from 17:00 to 19:00 is 21 yen / kWh. Therefore, the operation time calculation unit 16 extracts the time zone from 17:00 to 19:00 when the power rate is 21 yen / kWh as the cheapest time zone of the power rate. As a result, the operation time calculation unit 16 determines 19:00, which is the end of the time zone with the lowest power rate, as the operation end time, and calculates 18:00 as the third operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 21 yen.

  In FIG. 10, when the desired operation time is 1 o'clock, for example, the range searched by the operation time calculation unit 16 is a range from 14:00 to 1 o'clock. In this case, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and from 23:00 to 2 o'clock The electricity charge in the time period until is 8 yen / kWh. Therefore, the operation time calculation unit 16 extracts the time zone from 23:00 to 1 o'clock where the power rate is 8 yen / kWh as the cheapest time zone of the power rate. As a result, the operation time calculation unit 16 determines 1:00, which is the end of the time zone with the lowest power rate, as the operation end time, and calculates 24:00 as the third operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIG. 9 and FIG. 10, the description has been made so that only the time zone with the lowest power rate is searched from the current time to the desired operation time. However, the present invention is not limited to this. A plurality of third operation start times may be calculated by searching for bands. Further, the operation end time may be calculated every time the power rate changes between the current time and the desired operation time.

  Next, the fourth operation start time calculation process in step S24 of FIG. 3 will be described. FIG. 11 is a flowchart for explaining the fourth operation start time calculation process in step S24 of FIG.

  First, in step S61, the operation time calculation unit 16 searches for a time zone with the lowest power rate from the time obtained by subtracting the operation period from the desired operation time to the time obtained by adding the allowable period to the desired operation time. . The cheapest time zone of the electricity rate here is the cheapest time zone of the electricity rate from the time obtained by subtracting the operation period from the desired operation time to the time obtained by adding the allowable period to the desired operation time, It is not the cheapest time of the day for electricity charges.

  The allowable period represents a period that is allowed even if the desired operation end time or the desired operation end time is earlier or later, and is set to, for example, 5 hours in the present embodiment. Further, when the time from the current time to the desired operation time is long, it may be limited within the allowable period retroactively from the desired operation time. Although the allowable period is stored in advance, the user can set an arbitrary period. The permissible period may be different for each home appliance and stored, or the permissible period may be different according to the desired operation time or the operation time of the device.

  Next, in step S62, the operation time calculation unit 16 has a time zone with the lowest power rate between the time obtained by subtracting the operation period from the desired operation time and the time obtained by adding the allowable period to the desired operation time. Judge whether to do. Here, when it is determined that there is a time zone with the lowest power rate between the time obtained by subtracting the operation period from the desired operation time and the time obtained by adding the allowable period to the desired operation time (YES in step S62). In step S63, the operation time calculation unit 16 determines whether or not the desired operation time is included in the time zone with the lowest power rate.

  When it is determined that the desired operation time is not included in the time zone with the lowest power rate (NO in step S63), in step S64, the operation time calculation unit 16 sets the start point of the time zone with the lowest power rate as the fourth end. The operation start time is determined.

  On the other hand, when it is determined that there is no cheapest time zone between the time obtained by subtracting the operation period from the desired operation time and the time obtained by adding the allowable period to the desired operation time, that is, the desired operation time If the power charge does not change between the time obtained by subtracting the operation period from the time obtained by adding the permissible period to the desired operation time (NO in step S62), or the desired operation time is in the time zone with the lowest power charge If it is determined that it is included (YES in step S63), in step S65, the operation time calculation unit 16 determines the desired operation time as the operation end time.

  Next, in step S66, the operation time calculation unit 16 calculates a fourth operation start time by going back the operation period from the determined operation end time.

  FIG. 12 is a schematic diagram for explaining the fourth operation start time calculation process. In FIG. 12, the current time is 14:00, the operation period of the household electrical appliance 1 is 1 hour, the allowable period is 5 hours, and the desired operation time is 16:30. In addition, the power charge in the time zone from 14:00 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and the time from 23:00 to 2 o'clock The electricity charge for the band is 8 yen / kWh.

  First, the operation time calculation unit 16 starts at 21:30 (desired operation time (16:30) from 15:30 (time obtained by subtracting the operation period (1 hour) from the desired operation time (16:30)). ) To the time period obtained by adding the allowable period (5 hours) to the time period). In the time zone from 15:30 to 21:30, the power rate in the time zone from 15:30 to 17:00 is 28 yen / kWh, and the power rate in the time zone from 17:00 to 21:30 However, it is 21 yen / kWh. Therefore, the operation time calculation unit 16 extracts the time zone from 17:00 to 21:30 when the power rate is 21 yen / kWh as the cheapest time zone of the power rate.

  Next, the operation time calculation unit 16 determines whether or not the desired operation time is included in the time zone with the lowest power charge. In the example of FIG. 12, the operation time calculation unit 16 determines that the desired operation time (16:30) is not included in the cheapest time zone (17:00 to 21:30) of the power rate, and the power rate 17:00, which is the start of the cheapest time zone, is determined as the fourth operation start time. In this way, the fourth operation start time is determined at 17:00, and the household electrical appliance 1 is operated from 17:00 to 18:00. And when the electric power consumption per hour of the household appliances 1 is 1 kWh, the charged electricity bill is 21 yen.

  In FIG. 12, when the desired operation time is, for example, 21:00, the range searched by the operation time calculation unit 16 is a range from 20:00 to 2 o'clock. In this case, the power rate in the time zone from 20:00 to 23:00 is 21 yen / kWh, and the power rate in the time zone from 23:00 to 2 o'clock is 8 yen / kWh. Therefore, the operation time calculation unit 16 determines that the desired operation time (21:00) is not included in the cheapest time zone (23:00 to 2 o'clock), and at the start of the cheapest time zone. A certain 23:00 is determined as the fourth operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIG. 12, when the allowable period is 12 hours, for example, the range searched by the operation time calculation unit 16 is a range from 15:30 to 4:30. In this case, the power charge in the time zone from 15:30 to 17:00 is 28 yen / kWh, the power charge in the time zone from 17:00 to 23:00 is 21 yen / kWh, and it is 4 from 23:00. The power charge for the time period up to 30 minutes is 8 yen / kWh. Therefore, the operation time calculation unit 16 determines that the desired operation time (16:30) is not included in the cheapest time zone (23:00 to 4:30) of the power rate, and the time when the power rate is the lowest 23:00, which is the beginning of the belt, is determined as the fourth operation start time. At this time, when the electric power consumption per hour of the home appliance 1 is 1 kWh, the charged electricity bill is 8 yen.

  In FIG. 11 and FIG. 12, only the time zone with the lowest power rate is searched from the time obtained by subtracting the operation period from the desired operation time to the time obtained by adding the allowable period to the desired operation time. However, the present invention is not limited to this, and a plurality of fourth operation start times may be calculated by searching for the second lowest time zone. Alternatively, the operation end time may be calculated every time the power rate changes from the time obtained by subtracting the operation period from the desired operation time to the time obtained by adding the allowable period to the desired operation time.

  Next, the operation start time adjustment process in step S25 of FIG. 3 will be described. FIG. 13 is a flowchart for explaining the operation start time adjustment process in step S25 of FIG. Here, the operation start time is compared with the current time, and processing is performed when the operation start time is before the current time, that is, when execution is impossible.

  First, in step S71, the operation time calculation unit 16 determines whether or not the calculated first operation start time is after the current time. Here, when it is determined that the calculated first operation start time is not after the current time (NO in step S71), it is impossible to start the operation at the first operation start time. In S72, the operation time calculation unit 16 determines the first operation start time as the current time so that the operation can be started immediately.

  When it is determined that the calculated first operation start time is after the current time (YES in step S71), or when the current time is determined as the first operation start time, in step S73, an operation time calculation unit 16 determines whether or not the calculated second operation start time is after the current time. If it is determined that the calculated second operation start time is not after the current time (NO in step S73), the operation cannot be started at the second operation start time. In S74, the operation time calculation unit 16 determines the second operation start time as the current time so that the operation can be started immediately.

  When it is determined that the calculated second operation start time is after the current time (YES in step S73), or when the current time is determined as the second operation start time, in step S75, the operation time calculation unit 16 determines whether the calculated third operation start time is after the current time. If it is determined that the calculated third operation start time is not after the current time (NO in step S75), it is impossible to start the operation at the third operation start time. In S76, the operation time calculation unit 16 determines the third operation start time as the current time, and allows the operation to start immediately.

  When it is determined that the calculated third operation start time is after the current time (YES in step S75), or when the current time is determined as the third operation start time, in step S77, an operation time calculation unit 16 determines whether or not the calculated fourth operation start time is after the current time. Here, when it is determined that the calculated fourth operation start time is not after the current time (NO in step S77), it is impossible to start the operation at the fourth operation start time. In S78, the operation time calculation unit 16 determines the fourth operation start time as the current time so that the operation can be started immediately.

  When it is determined that the calculated fourth operation start time is after the current time (YES in step S77), or when the current time is determined as the fourth operation start time, the operation time calculation unit 16 Then, the operation start time adjustment process is terminated.

  Returning to FIG. 2, the processing after step S5 will be described.

  In step S <b> 5, the electricity bill calculation unit 17 includes first to fourth operation start times calculated by the operation time calculation unit 16, power rate information acquired by the power rate information acquisition unit 15, and an operation information reading unit. Each of the first to fourth driving start times calculated by the driving time calculating unit 16 based on the driving period information read by the driving information 13 and the electric energy information read by the driving information reading unit 13. Calculates the electricity bill charged when the vehicle is operated.

  The electricity bill calculation unit 17 calculates the electricity bill charged when the home appliance 30 is operated using the following equation (1). That is, the electricity bill calculation unit 17 multiplies the power rate Y (t) that changes with time by the amount of power P (t) required for the home appliance 1 to operate from the operation start time t1 to the operation end time t2. By integrating over the operation period until, the electricity bill charged when operated at each of the first to fourth operation start times is calculated.

  As shown in FIGS. 6, 8, 10, and 12, the electric bills are 24.5 yen at the first operation start time, 21 yen at the second operation start time, In the case of 3 driving start time, it is 28 yen, and in the case of 4th driving start time, it is 21 yen.

  Next, in step S <b> 6, the rank assigning unit 18 assigns ranks to the first to fourth operation start times in the order of cheaper electricity bills calculated by the electricity bill calculating unit 17.

  FIG. 14 is a diagram for explaining the order given to each of the first to fourth operation start times in the first embodiment.

  In FIG. 14, the electricity bill represents the electricity bill charged when the vehicle is operated at each of the first to fourth operation start times. Note that the electricity cost in FIG. 14 indicates the electricity cost charged when the vehicle is operated at each of the first to fourth operation start times calculated in the examples of FIGS. The electricity bill at the first operation start time is 24.5 yen, but rounded off to 25 yen. The value of the electricity bill represents how much it is cheaper with respect to the highest electricity bill, with the highest electricity bill of 0 yen being charged. The recommendation rank represents the rank assigned by the rank assigning unit 18.

  The rank assigning unit 18 assigns ranks in order from the highest value of the electricity bill. The electricity bill charged when the vehicle is operated at the first operation start time is 25 yen, the value of the electricity bill is +3 yen, and the recommendation ranking is No. 3. The electricity bill to be charged when the vehicle is operated at the second operation start time is 21 yen, the value of the electricity bill is +7 yen, and the recommendation ranking is 1st. The electricity bill charged when the vehicle is operated at the third operation start time is 28 yen, the value of the electricity bill is 0 yen, and the recommendation ranking is No. 4. The electricity bill charged when the vehicle is operated at the fourth operation start time is 21 yen, the value of the electricity bill is +7 yen, and the recommendation ranking is No. 2.

  Here, since the operation time is the same when operated at the second operation start time and when operated at the fourth operation start time, it is charged when operated at the second operation start time. The electricity cost charged is the same as that charged when the vehicle is operated at the fourth operation start time. When a plurality of operation start times with the same electricity bill are calculated, the same rank may be given to all, or the rank may be given at random. In FIG. 14, “No. 1” is assigned with the same ranking given to the second driving start time and the ranking given to the fourth driving start time.

  Further, when a plurality of operation start times having the same operation start time are calculated, the rank assigning unit 18 may leave only one operation start time and delete other operation start times. At this time, the operation time calculation unit 16 may calculate the operation start time again for the deleted operation pattern by changing the calculation condition by changing the condition, for example, by widening the permission period, as will be described later. .

  Returning to FIG. 2, in step S <b> 7, the notification unit 19 displays the first to fourth driving start times calculated by the driving time calculating unit 16 together with the ranks given by the rank assigning unit 18.

  Next, in step S <b> 8, the operation time selection receiving unit 20 receives the selection of the operation start time desired by the user from the first to fourth operation start times notified by the notification unit 19.

  FIG. 15A to FIG. 15D are diagrams illustrating examples of display screens displayed by the notification unit. The notification unit 19 displays a plurality of operation start times one by one in order. The notification unit 19 displays the display screens shown in FIGS. 15A to 15D in descending order.

  First, the alerting | reporting part 19 displays the driving | operation start time to which the ranking of "No. 1" was provided on the display screen. As shown in FIG. 15A to FIG. 15D, on the display screen, the recommendation order recommended by the home appliance 1, the operation start time when the home appliance 1 starts operation, from the operation start time to the operation end time And the electricity bill charged when the home appliance 1 is operated are displayed. Moreover, the alerting | reporting part 19 displays the selection item for receiving selection of the driving | operation start time displayed on a display screen. The selection item indicates whether the displayed operation start time is acceptable or whether another operation start time is viewed, and the user selects one of them.

  The operation time selection accepting unit 20 accepts selection of the operation start time desired by the user from among the plurality of operation start times notified by the notification unit 19. That is, when the operation start time displayed on the display screen is acceptable, the user presses the button corresponding to “Yes”, and when displaying another operation start time, the user presses the button corresponding to “No”. .

  When the operation start time displayed by the user is not selected, the notification unit 19 displays the operation start time assigned with the rank “No. 2” on the display screen. Thereafter, the notification unit 19 sequentially displays the operation start times assigned with the ranks of “No. 3” and “No. 4” on the display screen until the operation start time is selected.

  When the same operation start time is calculated as in the second operation start time and the fourth operation start time shown in FIG. 14, the notification unit 19 displays three operation start times. Further, when calculating the second operation start time, as described in FIG. 12, the second operation start time (23:00) calculated when the allowable period is set to be extended to 12 hours is duplicated. It may be displayed instead of the operation start time. The display screen shown in FIG. 15D displays the second operation start time calculated when the allowable period is set to 12 hours.

  Thus, by displaying a plurality of operation start times one by one on the display screen, the user can determine one by one whether the operation start times are permissible. Further, when the first operation start time is acceptable, it is not necessary to determine the operation start times after the second order, and the selection operation is facilitated.

  Next, a first modification of the display screen displayed by the notification unit will be described. FIG. 16 is a diagram illustrating a first modification of the display screen displayed by the notification unit. In FIG. 16, a plurality of operation start times are collectively displayed on the display screen. The notification unit 19 displays a plurality of operation start times in descending order.

  As shown in FIG. 16, the display screen includes a current time, a desired driving time input by the user, a period required for driving, a recommendation order recommended by the home appliance 1, and a plurality of driving starts when the home appliance 1 starts driving. The time, the operation time from the operation start time to the operation end time, and the electricity bill charged when the home appliance 1 is operated are displayed. Moreover, the alerting | reporting part 19 displays the selection item for accepting selection of one driving | running start time from the several driving | running start times displayed on a display screen. In the selection item, a sentence that prompts the user to select the operation start time desired from the plurality of operation start times displayed is displayed.

  Returning to FIG. 2, in step S <b> 9, the operation time storage unit 21 stores the operation start time received by the operation time selection reception unit 20.

  Next, in step S <b> 10, the operation control unit 23 determines whether or not the current time has reached the operation start time stored in the operation time storage unit 21. When it is determined that the current time is not the operation start time stored in the operation time storage unit 21 (NO in step S10), the standby state is entered, and the current time is stored in the operation time storage unit 21. The determination process in step S10 is repeated at a predetermined timing until the current operation start time is reached.

  On the other hand, when it is determined that the current time is the driving start time stored in the driving time storage unit 21 (YES in step S10), the driving control unit 23 starts driving the home appliance 1 in step S11. To do. The operation control unit 23 operates the home appliance 1 according to the operation condition acquired by the operation information acquisition unit 11.

  In this way, for each of a plurality of operation patterns of the household electrical appliance 1 defined according to the desired operation time, an operation start time or an operation end time at which the power charge is equal to or less than a predetermined charge is calculated, and the calculated plurality of operation start Since the user is notified of the time or a plurality of operation end times, it is possible to propose an operation start time or an operation end time that the user has not assumed, or to simplify the setting operation of the desired operation time performed by the user.

(Embodiment 2)
Next, the home appliance according to Embodiment 2 will be described. FIG. 18 is a diagram showing a configuration of a household electrical appliance according to Embodiment 2 of the present invention.

  18 includes a driving information acquisition unit 11, a driving information storage unit 12, a driving information reading unit 13, a communication unit 14, a power rate information acquisition unit 15, a driving time calculation unit 16, and an electricity bill calculation unit 17. , An order assignment unit 18, a notification unit 19, an operation time selection reception unit 20, an operation time storage unit 21, a clock unit 22, an operation control unit 23, and a time difference calculation unit 24. In addition, in the household electrical appliance 1 'which concerns on Embodiment 2, description is abbreviate | omitted about the same structure as the household electrical appliance 1 which concerns on Embodiment 1, and only a different structure is demonstrated.

  The time difference calculation unit 24 calculates a time difference between the operation start time or the operation end time specified by each of the plurality of operation start times calculated by the operation time calculation unit 16 and the desired operation time. That is, the time difference calculation unit 24 calculates the time difference between the operation end time specified by the first and second operation start times calculated by the operation time calculation unit 16 and the desired operation time, and the operation time calculation unit 16. The time difference between the third and fourth driving start times calculated by the above and the desired driving time is calculated.

  Based on the electricity cost calculated by the electricity cost calculating unit 17 and the time difference calculated by the time difference calculating unit 24, the rank assigning unit 18 has a plurality of operation start times (first to fourth operation start times). Give rankings to them.

  Next, the operation of home appliance 1 'in the second embodiment will be described.

  FIG. 19 is a flowchart for illustrating the operation of home appliance 1 ′ according to the second embodiment.

  The processes in steps S81 to S85 and S88 to S92 are the same as the processes in steps S1 to S5 and S7 to S11 shown in FIG.

  In step S86, the time difference calculation unit 24 calculates the time difference between the operation start time and the desired operation time specified by the first operation start time and the second operation start time calculated by the operation time calculation unit 16, and the operation time. A time difference between the operation end time specified by the third operation start time and the fourth operation start time calculated by the calculation unit 16 and the desired operation time is calculated.

  As shown in FIG. 6 described above, when the desired operation time (desired operation start time) is 16:30 and the calculated first operation start time is 16:30, it is calculated by the time difference calculation unit 24. The time difference between the operation start time (16:30) specified by the first operation start time and the desired operation time (16:30) is “0 minutes”.

  As shown in FIG. 8 described above, when the desired operation time (desired operation start time) is 16:30 and the calculated second operation start time is 17:00, the time difference calculation unit 24 calculates the time difference. The time difference between the operation start time (17:00) specified by the second operation start time and the desired operation time (16:30) is “30 minutes”.

  When the permission period is set to 12 hours when calculating the second operation start time, the second operation start time is 23:00. In this case, the time difference between the operation start time specified by the second operation start time and the desired operation time is “6 hours 30 minutes”.

  Further, as shown in FIG. 10 described above, when the desired operation time (desired operation end time) is 16:30 and the calculated third operation start time is 15:30, the time difference calculation unit 24 The time difference between the operation end time (16:30) specified by the third operation start time and the desired operation time (16:30) calculated by the above is “0 minutes”.

  Further, as shown in FIG. 12 described above, when the desired operation time (desired operation end time) is 16:30 and the calculated fourth operation start time is 17:00, the time difference calculation unit 24 calculates the time difference. The time difference between the operation end time (18:00) specified by the fourth operation start time and the desired operation time (16:30) is “90 minutes”.

  Returning to FIG. 19, in step S <b> 87, the rank assigning unit 18 performs a plurality of operation start times based on the electricity cost calculated by the electricity cost calculating unit 17 and the time difference calculated by the time difference calculating unit 24. To give a ranking.

  FIG. 20 is a diagram for describing the order given to each of the first to fourth operation start times in the second embodiment.

  In FIG. 20, the electricity bill represents the electricity bill charged when the vehicle is operated at each of the first to fourth operation start times. Note that the electricity charges in FIG. 20 indicate the electricity charges charged when the operation is performed at each of the first to fourth operation start times calculated in the examples of FIGS. 6, 8, 10, and 12. The value of the electricity bill represents how much it is cheaper with respect to the highest electricity bill, with the highest electricity bill of 0 yen being charged. The time difference is the time difference between the operation start time specified by the first operation start time and the desired operation time, the time difference between the operation start time specified by the second operation start time and the desired operation time, and the third operation start. The time difference between the operation end time specified by the time and the desired operation time and the time difference between the operation end time specified by the fourth operation start time and the desired operation time are shown. The value of the time difference is obtained by converting the time difference into an electricity bill. The longest time difference is 0 yen, and the time difference of 30 minutes is converted into an electricity bill of 1 yen. The total value is the sum of the value of the electricity bill and the value of the time difference. The recommendation rank represents the rank assigned by the rank assigning unit 18.

  Here, the operation time when operated at the second operation start time is the same as the operation time when operated at the fourth operation start time, but the time difference when operated at the second operation start time; Since the time difference when operated at the fourth operation start time is different, the total value of the value of the electricity cost and the value of the time difference is different. Alternatively, since the time at which the home appliances are operated is the same although the value of the time difference is different, only the higher value may be notified and the lower value may not be notified.

  In FIG. 20, the time difference corresponding to the fourth operation start time is 90 minutes and is the longest time difference corresponding to the first to fourth operation start times, so the value of the time difference is 0 yen, The total is 7 yen. In addition, since the time difference corresponding to the first operation start time is 0 minutes, the value of the time difference is +3 yen, and the total with the value of the electricity bill is 6 yen. Since the time difference corresponding to the second operation start time is 30 minutes, the value of the time difference is +2 yen, and the total with the value of the electricity bill is 9 yen. Since the time difference corresponding to the third operation start time is 0 minutes, the value of the time difference is +3 yen, and the total value with the value of the electricity bill is 3 yen.

  The rank assigning unit 18 assigns ranks in descending order of the sum of the value of the electricity bill and the value of the time difference. In FIG. 20, since the sum of values corresponding to the second operation start time is the highest, the first recommendation order is given. Then, the second, third, and fourth recommendation ranks are given to the fourth operation start time, the first operation start time, and the third operation start time, respectively.

  In the second embodiment, the time difference of 30 minutes is converted into a 1-yen electricity bill. However, the present invention is not particularly limited to this, and when the value of the electricity bill is more important, it is 1 hour. The time difference may be converted into a 1-yen electricity bill to increase the value of the electricity bill relative to the time difference. When the value of the time difference is more important, the time difference of 15 minutes may be converted into a 1-yen electricity bill to increase the value of the time difference with respect to the electricity bill.

  In addition, as described in FIG. 8, when the second operation start time is calculated, when the permission period is set to 12 hours, the second operation start time is 23:00, and the time difference is 6 hours 30 minutes. It becomes. In this case, the value of the electricity bill is +20 yen (28 yen-8 yen), the value of the time difference is -10 yen ((90 minutes-390 minutes) / 30 minutes x 1 yen), and the total value is 10 yen And the recommendation order is first.

  In this way, by setting a conversion factor for converting the time difference into the electricity bill, the value ratio between the electricity bill and the time difference can be changed. Further, since the order of recommendation to the user is determined in consideration of not only the electricity bill but also the time difference, it is possible to propose an operation start time that is more suitable for the user's preference.

  For example, the ratio may be varied depending on the type of home appliance or the user's preference. In a cooking device such as a rice cooker that sticks to the time of eating, the value of the electricity bill with respect to the time difference is increased so as to reduce the time difference between the operation end time and the desired operation time. For example, a time difference of 15 minutes is converted into an electricity bill of 1 yen. On the other hand, in a dishwasher that does not mind a slight change in the completion time, even if the time difference between the operation end time and the desired operation time is large, the value of the electricity bill with respect to the time difference is lowered so as to reduce the electricity bill. For example, the time difference of 1 hour is converted into an electricity bill of 1 yen.

  In addition, the electricity bill with respect to the time difference may be changed according to the driving time. For example, in the sleeping hours, the value of the electricity bill with respect to the time difference is lowered, or the morning and night time zones are raised.

  In addition, the conversion coefficient when calculating the total value of the electricity bill and the time difference in this way is stored in advance in the operation information storage unit 12, or externally via the operation information acquisition unit 13 or the communication unit 14. It is possible to change the setting from

  The home appliance remote control unit 41 refers to the clock unit 40 and remotely controls the operation of the first home appliance 5a based on the operation start time stored in the operation time storage unit 39. That is, the home appliance remote control unit 41 generates an operation start instruction signal for starting the operation of the first home appliance 5a when the current time is the operation start time stored in the operation time storage unit 39. The home appliance remote control unit 41 outputs the generated operation start instruction signal to the home communication unit 31. The in-home communication unit 31 transmits the operation start instruction signal generated by the home appliance remote control unit 41 to the in-home communication unit 54 of the first home appliance 5a.

  Alternatively, although not illustrated, when the first home appliance 5a includes the clock unit 40 and the operation control unit 55 determines that the current time is the operation start time received from the device control device 2, the operation of the first home appliance 5a is performed. May be configured to start.

  In the third embodiment, the first home appliance 5a and the second home appliance 5b include the driving information storage unit 52 and the driving information reading unit 53, but the present invention is not particularly limited thereto. The device control apparatus 2 may include an operation information storage unit 52 and an operation information reading unit 53. In this case, the driving information acquisition unit 51 acquires the driving conditions and the desired driving time, and outputs the acquired driving conditions and the desired driving time to the home communication unit 54. The in-home communication unit 54 transmits the operation condition and the desired operation time to the device control apparatus 2. The in-home communication unit 31 of the device control apparatus 2 receives the driving condition and the desired driving time transmitted by the first home appliance 5a, outputs the received driving condition to the driving information reading unit, and receives the received desired driving time. It outputs to the operation time calculation part 34. The driving information reading unit of the device control device 2 stores driving period information corresponding to the driving conditions received by the in-home communication unit 31 and power amount information corresponding to the driving conditions received by the home communication unit 31. Read from the section. The same applies to the fourth embodiment described later.

  In the third embodiment, the operating conditions for driving the first home appliance 5a, the desired operation start time indicating the desired operation start time or the desired operation end time of the first home appliance 5a desired by the user, and Is set in the first home appliance 5a by the user, and the device control apparatus 2 acquires this via the in-home communication unit 31, but the user operates the device control apparatus 2 to operate the operating condition. Alternatively, the desired operation time may be set. The same applies to the fourth embodiment described later.

  Next, the operation of the device control system in the third embodiment will be described.

  FIG. 22 is a flowchart for explaining the operation of the device control system according to the third embodiment. In the following description, an operation for determining the operation start time of the first home appliance 5a will be described.

  First, in step S101, the driving information acquisition unit 51 indicates a driving condition for driving the first home appliance 5a and a desired driving start time or a desired driving end time of the first home appliance 5a desired by the user. Get the desired driving time. The driving information acquisition unit 51 inputs the driving conditions for driving the first home appliance 5a and the desired driving time indicating the desired driving start time or desired driving end time of the first home appliance 5a desired by the user. Accept. The driving information acquisition unit 51 outputs the acquired driving conditions to the driving information reading unit 53 and outputs the acquired desired driving time to the home communication unit 54.

  Next, in step S <b> 102, the driving information reading unit 53 includes driving period information corresponding to the driving conditions acquired by the driving information acquiring unit 51 and power amount information corresponding to the driving conditions acquired by the driving information acquiring unit 51. Are read from the driving information storage unit 52. The driving information reading unit 53 outputs the read driving period information and power amount information to the home communication unit 54.

  Next, in step S <b> 103, the in-home communication unit 54 sends the desired driving time acquired by the driving information acquisition unit 51, the driving period information and the electric energy information read by the driving information reading unit 53 to the device control apparatus 2. Send.

  Next, in step S104, the in-home communication unit 31 of the device control apparatus 2 receives the desired operation time, operation period information, and power amount information transmitted by the in-home communication unit 54 of the first home appliance 5a. The in-home communication unit 31 outputs the received desired operation time and operation period information to the operation time calculation unit 34, and outputs the received operation period information and electric energy information to the electricity cost calculation unit 35.

  The processing in steps S105 and S106 is the same as the processing in steps S3 and S4 shown in FIG.

  Next, in step S <b> 107, the operation time calculation unit 34 determines the operation start time among the calculated plurality of operation start times, and operates other home appliances stored in the operation time storage unit 39. It is determined whether or not there is an operation start time that overlaps with the period, and when it is determined that there is an operation start time that overlaps, the operation start time that overlaps is deleted from the calculated plurality of operation start times. On the other hand, if it is determined that there is no overlapping operation start time, the process proceeds to step S108.

  In the third embodiment, the present invention is not particularly limited to this, and step S107 is not essential. In addition, the operation time calculation unit 34 refers to the operation time storage unit 39 to determine whether or not there is an operation start time that overlaps with the operation period of other home appliances. Without being limited to this, the driving time calculation unit 34 collects the driving start time and the driving period set in the other home appliances by the in-home communication unit 31, thereby overlapping the driving period of the other home appliances. It may be determined whether a start time exists. The same applies to the fourth embodiment described later.

  The processing in steps S108 to S113 is the same as the processing in steps S5 to S10 shown in FIG.

  When it is determined that the current time is the operation start time stored in the operation time storage unit 39 (YES in step S113), in step S114, the home appliance remote control unit 41 determines the first home appliance 5a. A driving start instruction signal for starting driving is generated and output to the in-home communication unit 31.

  Next, in step S115, the in-home communication unit 31 transmits the operation start instruction signal generated by the home appliance remote control unit 41 to the in-home communication unit 54 of the first home appliance 5a.

  Next, in step S116, the in-home communication unit 54 of the first home appliance 5a receives the operation start instruction signal transmitted by the in-home communication unit 31 of the device control apparatus 2.

  Next, in step S117, the driving control unit 55 starts driving the first home appliance 5a based on the driving conditions acquired by the driving information acquiring unit 51.

  Thus, for each of a plurality of operation patterns of home appliances defined according to the desired operation time, an operation start time or an operation end time at which the power charge is equal to or less than a predetermined charge is calculated, and the calculated plurality of operation start times Or, since a plurality of operation end times are notified to the user, it is possible to propose an operation start time or an operation end time that the user did not expect, and to simplify the setting operation of the desired operation time performed by the user. , User convenience can be improved.

  In Step 107 of the third embodiment, when the operation time calculation unit 34 determines that there are home appliances with overlapping operation periods, the operation start time is calculated from the calculated operation start times. Although it is deleted, the present invention is not particularly limited to this, and when the operation time calculation unit 34 determines that there are overlapping operation periods, the operation time calculation unit 34 overlaps with the home appliance that calculated the operation start time in the operation period. It may be determined whether the maximum value of the total amount of electric power with the other home appliances is smaller than a predetermined value.

  When it is determined that the maximum value of the total amount of electric power between the home appliance for which the operation start time is calculated and the other home appliances that are duplicated is greater than or equal to a predetermined value, the operation time calculation unit 34 calculates the plurality of calculated operations. The overlapping operation start time is deleted from the start time. In addition, when it is determined that the total maximum amount of electric power of the home appliance that has calculated the operation start time and other home appliances that have been overlapped is smaller than a predetermined value, the operation time calculation unit 34 starts the overlap operation Use without deleting the time. The same applies to the fourth embodiment described later. The predetermined value is, for example, 70% of the maximum amount of power that can be used in the home or the maximum amount of power that can be used in the home.

  In addition, when it is determined that there are household appliances with overlapping driving periods, the driving time calculation unit 34 may calculate the driving start time again so as not to include a period during which other household appliances with duplicate driving are included. . For example, when the period during which other duplicate home appliances are operated is from 18:00 to 19:00, the operation time calculation unit 34 removes the time from 18:00 to 19:00 and calculates the operation start time again. The same applies to the fourth embodiment described later.

  In addition, the driving information storage unit 52 may store a priority order given in advance for each home appliance, and may determine which home appliance has priority when it is determined that there are home appliances with overlapping driving periods. When it is determined that there are home appliances with overlapping operation periods, the operation time calculation unit 34 collects the priorities of the overlapping home appliances via the in-home communication unit 31, and the home appliances with higher priority are operated. The operation start time of the low-priority home appliances may be calculated again so that the period is not included. The same applies to the fourth embodiment described later.

  Moreover, although the apparatus control apparatus 2 is provided with the alerting | reporting part 37 and the driving time selection reception part 38, this invention is not specifically limited to this, The 1st household appliances 5a has an alerting | reporting part and an operation time selection reception part. You may prepare. In this case, the in-home communication unit 31 of the device control apparatus 2 transmits a plurality of operation start times to the first home appliance 5a together with the ranks given by the rank assigning unit 36, and the in-home communication unit of the first home appliance 5a 54 receives a plurality of operation start times assigned ranks. And the alerting | reporting part of the 1st household appliances 5a displayed the several driving | operation start time received by the subscriber | terminal communication part 54, and the driving time selection reception part of the 1st household appliances 5a was displayed by the alerting | reporting part. The selection of the operation start time by the user is received from among a plurality of operation start times. Thereafter, the in-home communication unit 54 of the first home appliance 5a transmits the operation start time selected by the operation time selection receiving unit to the device control apparatus 2, and the operation time storage unit 39 is received by the in-home communication unit 31. The operation start time is stored. The same applies to the fourth embodiment described later.

(Embodiment 4)
Subsequently, a device control system according to Embodiment 4 will be described. FIG. 23 is a diagram showing a configuration of a device control system according to Embodiment 4 of the present invention. The device control system shown in FIG. 23 includes a device control device 2 ′, a first home appliance 5a, and a second home appliance 5b.

  The first home appliance 5a and the second home appliance 5b include a driving information acquisition unit 51, a driving information storage unit 52, a driving information reading unit 53, a home communication unit 54, and a driving control unit 55. The first home appliance 5a and the second home appliance 5b have the same configuration, although the types are different. The device control device 2 ′ includes an in-home communication unit 31, a communication unit 32, a power rate information acquisition unit 33, an operation time calculation unit 34, an electricity cost calculation unit 35, a rank assignment unit 36, a notification unit 37, and an operation time selection reception unit 38. , An operation time storage unit 39, a clock unit 40, a home appliance remote control unit 41, and a time difference calculation unit 42. In the device control system according to the fourth embodiment, the description of the same configuration as that of the device control system according to the third embodiment is omitted, and only a different configuration is described.

  The time difference calculation unit 42 calculates a time difference between the operation start time or the operation end time specified by each of the plurality of operation start times calculated by the operation time calculation unit 34 and the desired operation time. The time difference calculator 42 has the same configuration as the time difference calculator 24 in the second embodiment.

  The rank assigning unit 36 assigns ranks to a plurality of operation start times based on the electricity cost calculated by the electricity cost calculating unit 35 and the time difference calculated by the time difference calculating unit 42. The rank assigning unit 36 has the same configuration as the rank assigning unit 18 in the second embodiment.

  Next, the operation of the device control system in the fourth embodiment will be described.

  FIG. 24 is a flowchart for explaining the operation of the device control system according to the fourth embodiment.

  The processing in steps S121 to S128 and S131 to S138 is the same as the processing in steps S101 to S108 and S110 to S117 shown in FIG. Further, the processing in steps S129 and S130 is the same as the processing in steps S86 and S87 shown in FIG.

  In this way, by setting a conversion factor for converting the time difference into the electricity bill, the value ratio between the electricity bill and the time difference can be changed. Further, since the order of recommendation to the user is determined in consideration of not only the electricity bill but also the time difference, it is possible to propose an operation start time that is more suitable for the user's preference.

  In the first to fourth embodiments, the operation time storage units 21 and 39 may store the history of the operation start time selected by the user for each home appliance for each home appliance. At this time, the operation time storage units 21 and 39 store the operation pattern corresponding to the operation start time or the operation end time selected by the user among the plurality of operation patterns in FIGS. 4 (A) to 4 (D). To do. The rank assigning units 18 and 36 may assign weighting coefficients in descending order of the number of selected driving patterns among the plurality of driving patterns. Thereby, the order of the driving start time corresponding to the driving pattern that is likely to be selected by the user can be increased.

  For example, in a dishwasher / garbage disposal machine, if the number of times the user selects an operation pattern calculated by using the user's input desired operation time as the operation start time increases, the operation pattern of FIG. The recommendation order can be raised and presented to the user. In addition, in the clothes washer / dryer and rice cooker, if the number of times the user selects an operation pattern calculated using the user's input desired operation time as the operation end time increases, the recommended order of the operation pattern in FIGS. Can be presented to the user.

  In the first to fourth embodiments, the operation time storage units 21 and 39 divide, for example, 24 hours into hourly time zones, and determine to which time zone the operation start time selected by the user belongs. And the frequency | count to which driving | operation start time belongs for every time slot | zone may be memorize | stored for every household appliances. The rank assigning units 18 and 36 may assign a weighting coefficient to a time zone having a large number of selected operation start times. Thereby, according to a user's life time zone, the order of the driving start time corresponding to the driving pattern with high possibility of being selected can be made high.

  For example, if the desired operation time of the rice cooker is often set at 7:00 am, which is the user's wake-up time, and if the number of times of selecting an operation pattern in which rice cooking ends before the desired operation time increases, 15 and 16, the recommendation order of the driving pattern can be raised and presented to the user.

  Moreover, in Embodiment 1-4, the driving time calculation parts 16 and 34 may calculate driving | running start time or driving | operation end time using the driving | operation pattern different for every household appliances. For example, when the home appliance is a rice cooker or a washing / drying machine, the operation time calculation units 16 and 34 assume that the user has priority over the operation start time over the operation start time. The operation end time is calculated using only the operation pattern. In addition, when the home appliance is a dishwasher or a garbage disposal machine, the operation time calculation units 16 and 34 assume that the operation start time has priority over the operation end time. The operation start time is calculated using only the operation pattern 2. Different driving patterns for each home appliance are stored in the driving information storage unit 12 in advance. In addition, in FIG. 15, FIG. 16, and FIG. 17 that are examples of display screens displayed by the notification unit, four candidates for driving start time are displayed. In this case, two candidates for driving start time are displayed. .

  In this way, since the operation start time or the operation end time is not calculated using all of the plurality of operation patterns, the operation start time or the operation end time is calculated using a part of the plurality of operation patterns. For example, if only the operation start time is calculated and compared using at least the first operation pattern and the second operation pattern, how much the power rate changes when the operation start time is shifted before and after the desired operation time The user can grasp what to do.

  In that case, the operation start time at which the power rate is the lowest in the first operation pattern and the operation start time at which the power rate is the second lowest, and the operation start at which the power rate is the lowest in the second operation pattern. You may make it increase a user's choice by calculating and alert | reporting time and the 2nd cheapest driving start time, respectively.

  Moreover, if only the operation end time is calculated and compared using at least the third operation pattern and the fourth operation pattern, how much the electric charge changes when the operation end time is shifted before and after the desired operation time. The user can grasp this. In addition, the processing time for calculating the operation time can be shortened.

  In that case, the operation start time with the lowest power charge in the third operation pattern and the operation start time with the second lowest power charge, and the operation start with the lowest power charge in the fourth operation pattern are started. You may make it increase a user's choice by calculating and alert | reporting time and the 2nd cheapest driving start time, respectively.

  In the first to fourth embodiments, home appliances at home have been described as examples of electrical devices. However, the present invention is not limited to this, and electrical devices that are handled in offices, factories, facilities, and the like, and generate electric energy. The same effect can be obtained in a power generator such as a gas turbine or a fuel cell, a storage battery control device that stores electric energy, and a charging control device for an electric vehicle or an electric motorcycle equipped with the storage battery.

  Further, the present invention may be distributed as a program by a storage medium or a communication medium, and installed in a server, a personal computer, or a microcomputer of an electric device to be executed.

  The electric device, the electric device control method, the electric device control program, and the electric device control device according to the present invention propose an operation start time or an operation end time that the user has not assumed, or a user's desired operation time. An electric device, an electric device control method, an electric device control program, and an electric device control device that can simplify setting operations, improve user convenience, and change an operation start time designated by the user.
