The control unit, after a first transmission of the setting signal, a predetermined time before the operation start time or the operation stop time indicated by the setting signal, transmits a signal to instruct starting or stopping of the operation the predetermined time later to the household electric appliance.
Additionally, in other embodiment, a household electric appliance capable of a reserved operation of performing an operation start or stop at a set time comprises: a receiving unit that receives a setting signal indicative of an operation start time or an operation stop time in the reserved operation of the household electric appliance from a predetermined server apparatus connected by way of a network; a control unit that controls the operation of the household electric appliance; and a storage unit that stores data. The control unit, after a first reception of the setting signal, a predetermined time before the operation start time or the operation stop time indicated by the setting signal, receives a setting signal instructing starting or stopping of the operation the predetermined time later, stores contents of the setting signal in the storage unit, and executes the reserved operation in accordance with the contents of the setting signal stored in the storage unit.
The above embodiments can provide the household electric appliance, the household electric system, and the server apparatus that perform an operation start or an operation stop on time at the reserved setting time and further have enhanced convenience in the operation reservation.
Preferred embodiments according to the present invention will now be described with reference to the drawings.
A remote control system for household electric appliances according to conventional technologies does not provide a solution to how to process overlapped reservations. For example, as to the remote control system according to Patent Document 1, there is no description of the case of the overlapped reservations made from a remote controller attached to the household electric appliance and from a mobile terminal connectable to the Internet.
The household electric appliance and the household electric system according to a first embodiment operate properly when overlapped reservation data are input from the remote controller attached to the household electric appliance and from the mobile terminal connectable to the Internet. Namely, the first embodiment provides the household electric appliance and the household electric system that give priority to convenience from user's viewpoint in such a case.
The household electric appliance and the household electric system according to the first embodiment will now be described with reference to
<1-1 Configuration>
1-1-1 Overall Configuration of Household Electric System
A configuration will now be described of the household electric system according to the first embodiment with reference to
The household electric system 10 according to the first embodiment has the air-conditioners 12-1 to 12-3, the rice cooker 13, a radio adaptor (communication device) 14, a mobile terminal 16, a gateway device (relay device) 18, a router device 26, the Internet 20, and a server apparatus 22.
In the first embodiment shown in
The radio adaptor (communication device) 14, arranged to be electrically connected to a control unit of each of the air-conditioners 12-1 to 12-3, communicates with the gateway device 18. The radio adaptor 14 receives an operation signal to operate the air-conditioners 12-1 to 12-3 transmitted from the gateway device 18 and outputs the received operation signal to the control unit of the air-conditioner 12. Based on this operation signal, the air-conditioners 12-1 to 12-3 perform a corresponding operation.
The radio adaptor 14 acquires identification information (e.g., manufacturing serial number, model number, etc.) of the air-conditioners 12-1 to 12-3 from the control unit of the air-conditioners 12-1 to 12-3 and transmits the information to the gateway device 18. The radio adaptor 14 may be disposed integrally with the air-conditioners 12-1 to 12-3. The radio adaptor 14 may be disposed to be attachable and detachable to and from the air-conditioners 12-1 to 12-3 so that the radio adaptor 14 can be connected to any of a plurality of air-conditioners 12-1 to 12-3. The rice cooker 13 according to the first embodiment communicates with the gateway device 18 by, for example, an integrated radio adaptor (not shown) incorporated in the main body of the rice cooker 13. The control unit will be described later of each of the air-conditioners 12-1 to 12-3.
Each radio adaptor 14 has a “connection” button 14a. The “connection” button 14a is a button for newly connecting individual radio adaptor 14 to the gateway device 18. When the “connection” button 14a is operated by the user, the radio adaptor 14 equipped with the “connection” button 14a acquires the identification information of the air-conditioners 12-1 to 12-3 from the control unit of the air-conditioners 12-1 to 12-3. The identification information is, for example, the manufacturing serial number or the model number. The radio adaptor 14 transmits the acquired identification information to the gateway device 18.
The mobile terminal 16 is a general-purpose portable terminal such as a smartphone and a tablet PC (personal computer). The mobile terminal 16 has a connection means of connecting with the Internet 20 and a communication means of communicating with the router device 26. The mobile terminal 16 (e.g., smartphone) can connect with the Internet 20 by way of a telephone network (e.g., 3G network).
The mobile terminal 16 can connect with the router device 26 and the household electric appliances by, for example, a Wi-Fi communication, a Bluetooth (registered trademark) communication, or an infrared communication, etc. In this case, a device for such a purpose (e.g., Wi-Fi antenna, etc.) is incorporated in the mobile terminal 16.
The router device 26 can communicate with the mobile terminal 16 by, for example, the Wi-Fi communication, etc. The router device 26 can communicate with the air-conditioners 12-1 to 12-3 and the rice cooker 13 by the router device 26 sending, by way of the gateway device (relay device) 18, a radio signal of a command, etc., received from the mobile terminal 16 and the radio adaptor 14 receiving the signal. In the example shown in
As described above, the gateway device (relay device) 18 relays the communication between the radio adaptor 14 and the router device 26. The gateway device 18 is installed inside the user's house 24. The gateway device 18 communicates with the radio adaptor 14, using, for example, a signal of a special small-scale frequency band (924.0 to 928.0 MHz) of the specified low power radio. The frequency band of the communication between the gateway device 18 and the radio adaptor 14 is preferably a low frequency band that reaches up to a long distance.
The mobile terminal 16 and the server apparatus 22 can connect with the Internet 20. Connected with the Internet 20, the mobile terminal 16 can acquire, for example, an application program to operate the air-conditioners 12-1 to 12-3 from the server apparatus 22 by way of the Internet 20. This server apparatus 22 is set up by a manufacturer of the air-conditioners 12-1 to 12-3 and, for example, builds a homepage of the manufacturer. Accordingly, an operator of the mobile terminal 16 operates the manufacturer's homepage to take the application program into the mobile terminal 16.
Installing of the above-described acquired application program in the mobile terminal 16 and starting of the installed program make it possible for the mobile terminal 16 to operate the air-conditioners 12-1 to 12-3. Namely, the operation of an operation screen of a touch panel 16a of the mobile terminal 16 makes it possible to generate and transmit the operation signal to operate the air-conditioners 12-1 to 12-3. The operation of the touch panel 16a of the mobile terminal 16, the generation of the operation signal, and the transmission of the operation signal will be described later.
The server apparatus 22 controls information, etc., necessary for an access and a verification with respect to the mobile terminal 16, the air-conditioners 12-1 to 12-3, the radio adaptor 14, and the gateway device 18. For example, the server apparatus 22 verifies (judges) whether the identification information of the mobile terminal 16 contained in a communication request signal from the mobile terminal 16 and the identification information of the mobile terminal stored (registered) in the gateway device 18 match. If these match, then the server apparatus 22 verifies the mobile terminal 16 making the communication request (trying to access) as a legitimate mobile terminal, permitting its communication with the household electric appliance inside the house 24.
Thus, the mobile terminal 16 accesses the server apparatus 22 by way of the Internet 20, outside the house 24. With the verification by the server apparatus 22, the mobile terminal 16 can indirectly communicate with the household electric appliances of the air-conditioners 12-1 to 12-3, etc., by way of the router device 26 and the gateway device 18. The mobile terminal 16 can also communicate directly with the household electric appliances of the air-conditioners 12-1 to 12-3, etc., by way of the router device 26 and the gateway device 18, inside the house 24. In this case, the mobile terminal 16 does not access the server apparatus 22 from the Internet 20.
1-1-2 Configuration of Air-Conditioner
The configuration will then be described of the air-conditioner according to the first embodiment with reference to
As shown in
The indoor machine 30 has an interface 32, a controller 33a, a remote controller receiving unit 34, a storage unit 35, and a timer 36. The indoor machine 30 is supplied with power from, for example, an AC source 31 as a commercial power source inside the house 24.
The interface (I/F) 32 performs exchange of data, etc., between the radio adaptor 14 and the air-conditioner 12-1 (controller 33a).
The controller (control unit) 33a controls an overall operation of the indoor machine 30. The controller 33a receives an instruction of a predetermined operation reservation action from the interface 32 and the remote controller receiving unit 34 as a receiving unit. Upon reception of the instruction of the predetermined operation reservation action, the controller 33a controls the indoor machine 30 to execute the operation reservation action and further transmits an instruction signal S33 to a controller 33b of the outdoor machine 40. Details of the operation reservation action will be described later.
The remote controller receiving unit 34 receives a remote controller operation signal from a main body remote controller of this air-conditioner 12-1 and transmits the signal to the controller 33a. The controller 33a in reception of the remote controller operation signal from the main body remote controller controls the operation of the air-conditioner 12-1 depending on the operation signal, in the same manner as in the case of the instruction from the mobile terminal 16.
The storage unit 35 stores fixed contents (operation start time, operation stop time, etc.) of a reserved operation. The data, etc., stored in the storage unit 35 will be described later.
The timer 36 notifies the controller 33a of the current time. The timer 36 notifies the controller 33a of the time that is set at zero when the operation reservation is set and that is counted down or counted up as the time elapses.
The outdoor machine 40 has the controller 33b, a fan drive circuit 41, a compressor drive circuit 42, a fan 43, and a compressor 44. The outdoor machine 40 is supplied with power from the indoor machine 30.
The fan drive circuit 41 receives a control signal C41 from the controller 33b to control the drive of the fan 43 in respect of the number of rotations, etc.
The compressor (compressing machine) drive circuit 42 receives a control signal C42 from the controller 33b to control the drive of the compressor (compressing machine) 44.
The fan 43 operates under control of the fan drive circuit 41 and generates an airflow to radiate or absorb heat of refrigerant in an outdoor heat exchanger (not shown).
The compressor (compressing machine) 44, under control of the compressor drive circuit 42, compresses the refrigerant (not shown) circulating inside the air-conditioner 12-1.
<1-2 Control Setting by Mobile Terminal>
A control setting by the mobile terminal to the air-conditioner according to the first embodiment will then be described. In the following, with respect to a temperature setting, etc., of the air-conditioners 12-1 to 12-3, the setting (remote control mode) will be described in the case of performing the same control as done by the attached remote controller, using the touch panel 16a of the mobile terminal 16. It is assumed that the mobile terminal 16 is the smartphone, etc., having the touch panel 16a and that an operation program for the air-conditioners 12-1 to 12-3 is already installed in the mobile terminal 16 from the server apparatus 22 and is already started.
In the mobile terminal 16, upon start of the operation program of the air-conditioner 12-1 (model number: CS-X00XX), a screen including various selection items is displayed on a display panel 16a of the mobile terminal 16, as shown in
If the item of “remote control” is selected by the user, selection buttons related with “remote control” are displayed on the display panel 16a, as shown in

(A-3) Likewise, if the item of “preset wind direction” inside the broken line in
(B-1) If the item of “transmit setting” in
(B-2) If “OK” in
(B-3) Thereafter, when the transmission is completed, the screen shown in
<1-3 Calendar Reservation Action>
A calendar reservation action in the air-conditioner 12-1 according to the first embodiment will then be described.
1-3-1 Setting of Calendar Reservation Action
Setting will be described of the calendar reservation action in the air-conditioner according to the first embodiment with reference to
In the mobile terminal 16, upon start of the operation program of the air-conditioner 12-1 (model number: CS-X00XX), the screen including various selection items is displayed on the display panel (touch panel) 16a of the mobile terminal 16, as shown in
If the item of “convenient functions” is selected by the user, the selection buttons related with the “convenient functions” are displayed on the display panel (touch panel) 16a, as shown in
If the selection button of the “calendar reservation” is selected by the user, the calendar of current year/month (June, 2013 in this example) is displayed, on the display panel (touch panel) 16a, as the setting item related with the “calendar reservation”, as shown in
If a date (June 14 in this example) on the displayed calendar is selected, the screen shown in
If “not yet set” of the “on-timer” or the “off-timer” is selected, the screen is displayed for selection (setting) of detailed time with respect to a reservation setting of the “on-timer” or the “off-timer”, as shown in
1-3-2 Calendar Reservation Determination Flow
A determination flow will then be described of the calendar-reserved operation in the household electric appliance according to the first embodiment with reference to
The controller 33a determines if the calendar reservation action described in “1-3-1” is set from both of the attached remote controller and the mobile terminal 16 (step S11). Specifically, the controller 33a, by reading out the data of the reservation contents stored in the storage unit 35, determines if the reservation action (operation) is set from both of the attached remote controller and the mobile terminal 16. If the reservation operation is not set from both of the attached remote controller and the mobile terminal 16 (No at step S11), then this determination flow is finished.
If the reservation action (operation) is set from both of the attached remote controller and the mobile terminal 16 (Yes at step S11), then the controller 33a determines if there is any overlapping of the operation times in the two reservations (step S12). Specifically, the controller 33a refers to the contents of the two reservations stored in the storage unit 35 to determine if there are overlapped operation times.
If there are overlapped operation times (Yes at step S12), then the controllers 33a and 33b preferentially select the earlier start time out of the two overlapped operation reservations and control so that the air-conditioner 12-1 will start its operation at that start time (step S13). Specifically, the controller 33a, referring to the time data of the two overlapped operation reservations stored in the storage unit 35, preferentially select the earlier start time and transmits the instruction signal S33 to the controller 33b so that the operation start will be performed at that start time. The controller 33b in reception of the instruction controls the start of the operation of the outdoor machine 40 so that the operation start will be performed at the earlier start time.
On the other hand, if there are no overlapped operation times (No at step S12), then the controllers 33a and 33b control so that the operation start will be performed at the reserved time (step S14).
After step S13, the controllers 33a and 33b preferentially select the earlier stop time out of the two stop times of the overlapped reservations and control so that the operation stop of the air-conditioner 12-1 will be performed at that stop time (step S15). Specifically, the controller 33a, referring to the time data of the two overlapped operation reservations stored in the storage unit 35, preferentially select the earlier stop time and transmits the instruction signal S33 so that the operation stop will be performed at that stop time. The controller 33b in reception of the instruction controls the stop of the operation of the outdoor machine 40 so that the operation stop will be performed at the earlier stop time.
On the other hand, after step S14, the controllers 33a and 33b control so that the operation stop will be performed at the reserved time (step S16). The above completes the determination flow.
<1-4 Effect>
The household electric appliance and the household electric system according to the first embodiment can have the following effect (1).
(1) A space of more comfortable temperature can be provided and the convenience can be enhanced.
As described above, in the household electric appliance and the household electric system according to the first embodiment, when the reservation operation is set from both of the remote controller attached to the air-conditioner and the mobile terminal 16 and when there are overlapped operation times, the controllers 33a and 33b preferentially select the earlier start time in the two reservations and perform the operation start at that start time (step S13). This is based on the view that when there is the overlapping of the operation time zones of the air-conditioner, the earlier start time best reflects the user's intention, with respect to the operation start.
As shown in
Further, when there are overlapped operation times, the controller 33a preferentially selects the earlier stop time out of the two stop times and performs the operation stop at that stop time (step S15). This is based on the view that when there is the overlapping of the operation time zones of the air-conditioner, the earlier stop time best reflects the user's intention, with respect to the operation stop.
For example, it can be assumed that the later stop time is set extremely later than the earlier stop time. In such a case, it is often apparent that this later stop time has been set due to the user's error. Then, if a priority is given to the later stop time, the operation will be continued up to the later stop time, resulting in an unnecessary waste of electricity by a useless operation. Therefore, from a standpoint of suppressing the wasteful operation due to the user's erroneous setting as much as possible, giving a priority to the earlier stop time as described above puts greater emphasis on the user's viewpoint.
As shown in
Thus, according to the configuration and the action described above, when the operation reservation is set from both of the mobile terminal 16 and the attached remote controller and when the operation times partially overlap, a priority is given to the operation start time and the operation stop time that can be deemed to be effective from the user's viewpoint. This makes it possible to further enhance the convenience of the household electric appliance. In light of greater emphasis on the user's viewpoint, customer satisfaction can be further enhanced.
The conventional (e.g., described in Patent Document 1) remote control system transmits an operation start signal or an operation stop signal to a device whose designation code, etc., are input in a menu screen beforehand, when the time input in the menu screen beforehand comes. In the case of the conventional remote control system, however, when the server apparatus is busy at the operation start time or the operation stop time at which the signal is to be transmitted, it is possible that the operation signal or the stop signal cannot be transmitted at the reserved time. Then, there is a risk of the device not operating or stopping normally at the reserved time.
In light of the above problem, a second embodiment according to the present invention provides the household electric appliance, the household electric system, and the server apparatus capable of accurately performing the operation start or the operation stop on time at a set time reserved by the user.
The household electric appliance, the household electric system, and the server apparatus according to the second embodiment will now be described with reference to
<2-1 Configuration>
2-1-1 Overall Configuration of Household Electric System
The configuration of the household electric system according to the second embodiment is substantially the same as that of the household electric system according to the first embodiment shown in
The household electric system 10 according to the second embodiment has, in the same manner as in the first embodiment, the air-conditioners 12-1 to 12-3, the rice cooker 13, the radio adaptor (communication device) 14, the mobile terminal 16, the gateway device (relay device) 18, the router device 26, the Internet 20, and the server apparatus 22.
2-1-2 Configuration of Air-Conditioner
The configuration of the air-conditioner according to the second embodiment is substantially the same as that of the air-conditioner according to the first embodiment shown in
The air-conditioner 12-1 according to the second embodiment, like the air-conditioner according to the first embodiment, is composed of the indoor machine 30 and the outdoor machine 40. As shown in
2-1-3 Configuration of Server Apparatus
The configuration will then be described of the server apparatus 22 according to the second embodiment with reference to
The interface (I/F) 22-1 is a communicating unit that, under control of the control unit 22-2, performs an exchange of data between the mobile terminal 16 and the router device 26 and the server apparatus 22 by way of the Internet 20.
The control unit 22-2 controls the overall operation of the server apparatus 22. The control unit 22-2 controls the household electric system including the household electric appliances such as the air-conditioner 12-1 to perform the action after the calendar reservation (to be described later). Specifically, the control unit 22-2 receives information indicative of the operation start time or the operation stop time in the reserved operation of the air-conditioner 12-1 from the mobile terminal 16 and transmits a setting signal indicative of the operation start time or the operation stop time to the air-conditioner 12-1. Further, after a first transmission of the setting signal, a predetermined time before the operation start time or the operation stop time indicated by the setting signal, the control unit 22-2 transmits a signal (reservation signal) to instruct the operation starting or stopping the predetermined time later to the air-conditioner 12-1.
The data storage unit 22-3, under control of the control unit 22-2, stores control programs, application programs, and necessary data for execution of the household electric system. The data storage unit 22-3 stores, for example, the information indicative of the operation start time or the operation stop time in the operation reservation, to be transmitted from the mobile terminal 16. The data storage unit 22-3 is composed of, for example, an HDD (Hard Disc Drive) or an SSD (Solid State Drive).
<2-2 Calendar Reservation Action>
2-2-1 Setting of Calendar Reservation Action
The air-conditioners 12-1 to 12-3 according to the second embodiment, in the same manner as in the air-conditioners according to the first embodiment, perform the setting of the calendar reservation action shown in
2-2-2 Action Flow after Calendar Reservation
An action flow after the calendar reservation will then be described in the household electric system according to the second embodiment with reference to
As described in “1-3-1 Setting of Calendar Reservation Action”, the setting is performed, from the mobile terminal 16, of the calendar reservation action to specify the operation action start time and the operation action stop time of the air-conditioner 12-1 (step S61).
Then, the setting contents of the calendar reservation action are accepted by the server apparatus 22 from the mobile terminal 16 by way of the communication channel. The accepted setting contents of the calendar reservation action are stored by the control unit 22-2 of the server apparatus 22 in the data storage unit 22-3 (step S62).
Then, the server apparatus 22 notifies the setting contents of the calendar reservation action to the air-conditioner 12-1 by way of the Internet 20. The controller 33a of the notified air-conditioner 12-1 lights up a main body display unit of the indoor machine 30 (step S63). This makes it possible to inform a person inside the house 24 in which the air-conditioner 12-1 is installed that, for example, the calendar reservation was set from outside the house 24 by the mobile terminal 16. In the case of this example, a timer lamp, etc., of the main body display unit start to light from 0:00 am at which the reservation was set.
Then, the server apparatus 22 notifies an operation start reservation signal to the air-conditioner 12-1 by way of the Internet 20, the predetermined time before an operation start reserved time (step S64). In this example, the server apparatus 22 notifies the operation start reservation signal to the air-conditioner 12-1 by way of the interface 32 at time “7:30”, the predetermined time “30 minutes” before the operation start reserved time “8:00”.
The notified controller 33a stores the received operation start reservation signal in the storage unit 35. Upon completion of the storage thereof in the storage unit 35, the controller 33a sends back a response signal to the server apparatus 22 (step S65).
Then, the server apparatus 22 makes an inquiry to the air-conditioner 12-1 periodically with a predetermined time interval until the response signal from the air-conditioner 12-1 is sent back to confirm the acceptance. The inquiry made by the server apparatus 22 is of the same contents as those notified at step S64 and this inquiry is made repeatedly (step S66). In this example, the server apparatus 22 makes the inquiry to the air-conditioner 12-1 periodically with the predetermined time “10 minute” interval by repeatedly transmitting the same reservation signal as at step S64.
The controller 33a in reception of the inquiry sends back a response signal of the timer 36 to the server apparatus 22. Further, the controller 33a updates the time up to the operation start stored in the storage unit 35 so that it can start the operation of the air-conditioner at the time after an elapse of the predetermined time from the time at which the inquiry is received. Namely, the controller 33a updates the time up to the operation start stored in the storage unit 35 to such as 30 minutes later, 29 minutes later, . . . 15 minutes later (step S67). For example, when “10 minutes” have passed from the time at which the reservation signal of 30 minutes before the operation start time was received from the server apparatus 22, the controller 33a updates the time up to the operation start stored in the storage unit 35 so that the operation will be started 20 minutes later.
The server apparatus 22 determines whether the reservation is correctly set, based on the time of the timer 36 of the air-conditioner 12-1 (step S68). For example, the server apparatus 22 confirms whether the time of the timer 36 of the air-conditioner 12-1 matches the value to be set after an elapse of “10 minutes” from the time set at the time of the transmission of the operation start reservation signal of step S64.
If the timer 36 of the air-conditioner 12-1 is not normal, namely, the reservation action is not set correctly (No at step S68), then the server apparatus 22 transmits a notification signal to the mobile terminal 16 from which the reservation is set. From the server apparatus 22 the mobile terminal 16 receives the notification signal to the effect that the reserved time of the operation start of the air-conditioner 12-1 is abnormal (step S69). This makes it possible for the user to know that the reserved time of the operation start of the air-conditioner 12-1 is abnormal.
The controllers 33a and 33b of the air-conditioner 12-1, when judging, based on the time of the timer 36, that the reserved time of the operation start has come, perform the operation start (step S70). In this example, when judging based on the time notified by the timer 36 that the reserved time of the operation start “8:00” has come, the controllers 33a and 33b perform the operation start in the operation mode set previously, for example, in the “cooling” mode.
Further, the following action flow of the operation stop is executed in the same manner as the foregoing action flow of the operation start. Namely, the server apparatus 22 notifies an operation stop reservation signal to the air-conditioner 12-1 by way of the Internet 20, the predetermined time before an operation stop reserved time (step S71). In this example, the server apparatus 22 notifies the operation stop reservation signal to the air-conditioner 12-1 by way of the interface 32 at time “9:30”, the predetermined time “30 minutes” before the operation stop reserved time “10:00”.
The notified controller 33a stores the received operation stop reservation signal in the storage unit 35. Upon completion of the storage thereof in the storage unit 35, the controller 33a sends back a response signal to the server apparatus 22 (step S72).
Then, the server apparatus 22 makes an inquiry to the air-conditioner 12-1 periodically with a predetermined time interval until the response signal from the air-conditioner 12-1 is sent back to confirm the acceptance. The inquiry made by the server apparatus 22 is of the same contents as those notified at step S71 and this inquiry is made repeatedly (step S73). In this example, the server apparatus 22 makes the inquiry to the air-conditioner 12-1 periodically with the predetermined time “10 minute” interval by repeatedly transmitting the same reservation signal as at step S71.
The controller 33a in reception of the inquiry sends back a response signal of the timer 36 to the server apparatus 22. Further, the controller 33a updates the time up to the operation stop stored in the storage unit 35 so that it can stop the operation of the air-conditioner at the time after an elapse of the predetermined time from the time at which the inquiry is received (step S74). For example, when “10 minutes” have passed from the time at which the reservation signal of 30 minutes before the operation stop time was received from the server apparatus 22, the controller 33a updates the time up to the operation stop stored in the storage unit 35 so that the operation will be stopped 20 minutes later.
The server apparatus 22 determines whether the reservation is correctly set, based on the time of the timer 36 of the air-conditioner 12-1 (step S75). For example, the server apparatus 22 confirms whether the time of the timer 36 of the air-conditioner 12-1 matches the value to be set after an elapse of “10 minutes” from the time set at the time of the transmission of the operation stop reservation signal of step S71.
If the timer 36 of the air-conditioner 12-1 is not normal, namely, the reservation action is not set correctly (No at step S75), then the server apparatus 22 transmits a notification signal to the mobile terminal 16 from which the reservation is set. From the server apparatus 22 the mobile terminal 16 receives the notification signal to the effect that the reserved time of the operation stop of the air-conditioner 12-1 is abnormal (step S76). This makes it possible for the user to know that the reserved time of the operation stop of the air-conditioner 12-1 is abnormal.
The controllers 33a and 33b of the air-conditioner 12-1, when judging, based on the time of the timer 36, that the reserved time of the operation stop has come, perform the operation stop in the operation mode set previously, for example, in the “cooling” mode (step S77). In this example, when the reserved time of the operation stop “10:00” has come based on the time notified by the timer 36, the controllers 33a and 33b perform the operation stop.
The example of the action flow shown in
As shown in
Then, the air-conditioner 12-1, notified of the operation start reservation signal at time “7:30”, the predetermined time “30 minutes” before the operation start reserved time “8:00”, from the server apparatus 22 (step S64), has the operation start reservation set.
Then, the air-conditioner 12-1, by receiving the inquiry from the server apparatus 22 periodically with the predetermined time “10 minute” interval, is asked to confirm whether the operation start reservation is set (step S66).
Then, when the operation start reserved time “8:00” has come, based on the time notified from the timer 36, the air-conditioner 12-1 performs the operation start in the operation mode previously set, for example, the “cooling” mode (step S70).
Then, the air-conditioner 12-1, notified of the operation stop reservation signal at time “9:30”, the predetermined time “30 minutes” before the operation stop reserved time “10:00”, from the server apparatus 22 (step S71), has the operation stop reservation set.
Then, the air-conditioner 12-1, by receiving the inquiry from the server apparatus 22 periodically with the predetermined time “10 minute” interval, is asked to confirm whether the operation stop reservation is set (step S73).
Then, when the operation stop reserved time “10:00” has come, based on the time notified from the timer 36, the air-conditioner 12-1 performs the operation stop.
In this example, as described above, description has been made citing as an example the case in which the reservation signal of the operation start and the operation stop is notified to the air-conditioner 12-1, with the predetermined time before the reserved time of the operation start and the operation stop set at 30 minutes. The predetermined times before the reserved time, however, are not limited to 30 minutes but may be made changeable independently of each other, as required.
<2-3 Effect>
The household electric appliance, the household electric system, and the server apparatus according to the second embodiment can have the following effect (1).
(1) The operation start and the operation stop can be performed accurately on time at the reserved set time.
As described above, the air-conditioner (household electric appliance) 12-1 is a household electric appliance capable of the reserved operation of performing the start and the stop of the operation at the set time. The air-conditioner has the interface 32, the controllers (control unit) 33a and 33b, and the storage unit 35. The interface 32 receives the setting signal indicative of the operation start time or the operation stop time in the reserved operation of the air-conditioner 12-1 from the predetermined server apparatus 22 connected by way of the Internet 20. The controllers (control unit) 33a and 33b control the overall operation of the air-conditioner 12-1. The storage unit 35 stores predetermined data.
Further, the controllers 33a and 33b, after the first reception of the setting signal (step S63), the predetermined time before the time of the operation start or the operation stop indicated by the setting signal, receive the setting signal to instruct the operation starting or stopping the predetermined time later. The controllers 33a and 33b then store contents of the setting signal in the memory unit 35 (step S65, step S72) and execute the reserved operation in accordance with the contents of the setting signal stored in the storage unit 35.
According to the configuration and the operation described above, even if, for example, the server apparatus 22 is busy or congested, the server apparatus 22 transmits, the predetermined time earlier, the reservation signal to start or stop the operation the predetermined time later to the air-conditioner 12-1 (step S64, step S71). Consequently, the air-conditioner 12-1 that receives the reservation signal the predetermined time earlier can perform the operation start or the operation stop accurately on time at the reserved setting time even if the server apparatus 22 is busy. The configuration and the operation described above, which can avoid the communication at the busy time of the server apparatus 22, are effective in reducing the load of the server apparatus 22.
Further, when the household electric appliance is the air-conditioner as in this example, a plurality of air-conditioners connected to the server apparatus 22 often have the operation start times and the operation stop times close to one another, because of the characteristics of the household electric appliance. The household electric system according to the second embodiment can avoid the congested communication due to such closeness, resulting in a great advantage of reduced load of the server apparatus 22.
an example of same action as that of remote controller attached to main body)]
The household electric appliance, the household electric system, and the server apparatus according to a third embodiment will be described with reference to
In the third embodiment, the calendar reservation set by the mobile terminal 16 is the same as the calendar reservation set by the remote controller attached to the main body of the air-conditioners 12-1 to 12-3.
The third embodiment, however, is so configured that, in the case of the calendar reservation by the remote controller, a plurality of reservations cannot be set within a predetermined time (e.g., 90 minutes). Namely, the third embodiment is so configured that a space of a predetermined time (e.g., 90 minutes) or longer must be placed between two reservations.
It may be so arranged that, in the case of the reservation setting by the mobile terminal as well, a space of a predetermined time (e.g., 90 minutes) or longer must be placed between two reservations, in the same manner as in the case of the reservation setting by the remote controller.
The household electric appliance, the household electric system, and the server apparatus according to the third embodiment can have the same effect as that of (1) above. Further, the household electric appliance, the household electric system, and the server apparatus according to the third embodiment make it possible for the remote controller attached to the main body to perform the calendar reservation by the mobile terminal 16.
The present disclosure is applicable to the household electric appliance such as the air-conditioner and the household electric system controlling the household electric appliance.
