[Diagram 5]FIG. 4 is a sequence diagram showing a restriction display method in the air conditioning system of the present embodiment. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. In the drawings, the same or corresponding parts are designated by the same reference characters and description thereof will not be repeated.

[0011] First, an air conditioning system 100 and an electric device 10 of the present embodiment will be described with reference to FIG. 1 and FIG. 2. FIG. 1 is a diagram showing the air conditioning system 100 of the present embodiment. FIG. 2 is a block diagram of the air conditioning system 100 of the present embodiment. The air conditioning system 100 includes an electric device 10 and one or more operation terminals 20. In FIG. 1, as an example, the air conditioning system 100 includes operation terminals 20A and 20B. In FIG. 2, one operation terminal 20 is representatively shown. The electric device 10 is, for example, an air conditioner (air conditioner) installed in a room RM, and conditions the air in the room RM. The electric device 10 is capable of bidirectional communication with the operation terminal 20 via a network 30. The operation terminal 20 is capable of bidirectional communication with the electric device 10 via the network 30. The operation terminal 20 is, for example, a smartphone, a tablet terminal, a notebook personal computer (notebook PC), or a desktop personal computer (desktop PC).

[0012] [Electrical Equipment 10] 2, the electrical device 10 includes an air conditioning unit 11, a reception unit 12, a control unit 13, a display unit 14, and a storage unit 15. The air conditioning unit 11 adjusts at least one property of air temperature, humidity, and airflow.

[0013] The reception unit 12 receives air conditioning settings related to the air conditioning unit 11. Specifically, the reception unit 12 includes, for example, a communication unit 121 and an infrared receiving unit 122. The communication unit 121 receives a signal including the air conditioning settings transmitted from the operation terminal 20 via a network 30 including a wired LAN (Local Area Network) or a wireless LAN. The infrared receiving unit 122 receives an infrared signal including the air conditioning settings transmitted from a remote control (not shown).

[0014] The control unit 13 includes a processor such as a CPU (Central Processing Unit). The control unit 13 acquires the air conditioning settings contained in the signal received by the communication unit 121 or the infrared signal received by the infrared receiving unit 122, and controls the air conditioning unit 11 based on the acquired air conditioning settings.

[0015] Display unit 14 is, for example, a liquid crystal display, and displays information related to the air conditioning settings under the control of control unit 13. Specifically, control unit 13 generates an air conditioning setting image including the temperature, humidity, etc. indicated by the air conditioning settings, and displays it on display unit 14. Note that the air conditioning setting image may include the air volume and air direction of air conditioning unit 11 in addition to the temperature and humidity.

[0016] Also, for example, the display unit 14 may be one or more LED lamps. In this case, the control unit 13 controls the turning on and off of the corresponding LED lamps based on the air conditioning settings. Specifically, the control unit 13 changes the lighting color of the LED lamps or the number of LED lamps to be turned on according to the air conditioning settings.

[0017] The storage unit 15 stores various data. For example, the storage unit 15 stores a control program for operating the electric device 10. The control unit 13 controls the operation of the electric device 10 by executing the control program.

[0018] [Operation terminal 20] The operation terminal 20 includes a control unit 21, a storage unit 22, a display unit 23, an operation unit 24, and a communication unit 25. The control unit 21 controls the storage unit 22, the display unit 23, the operation unit 24, and the communication unit 25.

[0019] The control unit 21 includes a processor such as a CPU (Central Processing Unit).

[0020] The storage unit 22 stores various data. For example, the storage unit 22 stores a control program for driving the operation terminal 20. The control unit 21 controls the operation of the operation terminal 20 by executing the control program.

[0021] The storage unit 22 may also store an application program related to the control of the electric device 10. For example, the control unit 21 may control the electric device 10 by executing the application program.

[0022] The display unit 23 displays an operation screen or the results of various processes, and includes a liquid crystal display or an organic EL display.

[0023] The operation unit 24 may include a touch sensor. The display unit 23 and the operation unit 24 may be integrated into a touch panel. On the touch panel, for example, various keys for instructing the type of job and the contents of the job are displayed. Alternatively, the operation unit 24 may include buttons or a keyboard.

[0024] The communication unit 25 communicates with an external device. Here, the communication unit 25 transmits a specific signal to at least the electric device 10 via the network 30. The communication unit 25 may also receive a specific signal from at least the electric device 10.

[0025] For example, the communication unit 25 transmits a signal including the air conditioning settings of the electrical appliance 10 to the electrical appliance 10. Specifically, when the user operates the operation unit 24 according to the screen displayed on the display unit 23 by executing an application program to input the air conditioning settings of the electrical appliance 10 to the operation terminal 20, the control unit 21 generates a signal including the input air conditioning settings. The communication unit 25 transmits the signal including the air conditioning settings generated by the control unit 21 to the electrical appliance 10 via the network 30.

[0026] [Restriction Settings] In this embodiment, a setting range can be set for the air conditioning setting. For example, in an electrical device 10 whose adjustable temperature range is 15°C to 30°C, a limit setting can be set to limit the temperature setting range to 20°C to 26°C.

[0027] Specifically, to set a limit setting on the electrical device 10, for example, the user operates a remote control to transmit an infrared signal including a limit setting instruction to set the limit setting from the remote control to the electrical device 10. The limit setting instruction includes information that the limit range is 20°C to 26°C.

[0028] The reception unit 12 of the electrical device 10 receives a limit setting that indicates a limit range of the air conditioning setting. Specifically, the infrared receiving unit 122 receives an infrared signal that includes a limit setting instruction transmitted from a remote control.

[0029] The control unit 13 acquires the limit setting instruction contained in the infrared signal received by the infrared receiving unit 122, and stores it in the memory unit 15. The control unit 13 controls the air conditioning unit 11 based on the limit setting instruction stored in the memory unit 15.

[0030] Specifically, the control unit 13 controls the adjustment range of the air temperature by the air conditioning unit 11 to be within the restricted range (20°C to 26°C). For example, in the case where the air conditioning setting (temperature setting) in the electrical device 10 before the restrictive setting was accepted was 20°C, the control unit 13 maintains the air conditioning setting (temperature setting) at 20°C and controls the air conditioning unit 11 based on the maintained air conditioning setting. On the other hand, in the case where the air conditioning setting (temperature setting) before the restrictive setting was accepted was 19°C, the control unit 13 changes the air conditioning setting (temperature setting) to 20°C and controls the air conditioning unit 11 based on the changed air conditioning setting. In this way, in the electrical device 10, the state in which the air conditioning unit 11 operates based on the restrictive setting is called the restricted state.

[0031] In this embodiment, the limit setting instruction can be sent not only from a remote control, but also from the operation terminal 20. For example, when the user operates the operation unit 24 in accordance with a screen displayed on the display unit 23 by executing an application program, the control unit 21 displays a limit input screen on the display unit 23 requesting the user to input a limit range for the air conditioning settings.

[0032] When the user operates the operation unit 24 to input the limit range to the operation terminal 20 according to the limit input screen displayed on the display unit 23, the control unit 21 generates a limit setting instruction generated in the remote control and generates a signal including the limit setting instruction. The communication unit 25 transmits the signal including the limit setting instruction generated by the control unit 21 to the electrical device 10 via the network 30.

[0033] 1, when the air conditioning system 100 includes a plurality of operation terminals 20, at least one of the operation terminals 20 is a management terminal capable of transmitting a limit setting instruction. In the air conditioning system 100, the operation terminals 20 other than the management terminal cannot transmit a limit setting instruction.

[0034] [Electrical equipment restriction markings] For example, when the electric appliance 10 is in a restricted state, if the electric appliance 10 receives an air-conditioning setting outside the restricted range transmitted from the remote control or the operation terminal 20, the electric appliance 10 cannot reflect the received air-conditioning setting.

[0035] On the other hand, for a user who sent the air conditioning settings using the remote control or operation terminal 20, the air conditioning settings may not be reflected, and the user may mistakenly assume that there is a malfunction.

[0036] In this embodiment, the display unit 14 displays a restriction display indicating that the air conditioning unit 11 is in a restricted state. For example, when the control unit 13 receives a restriction setting instruction transmitted from the remote control or the operation terminal 20 and controls the air conditioning unit 11 to the restricted state, the control unit 13 causes the display unit 14 to display the restriction display.

[0037] Specifically, when the display unit 14 is a liquid crystal display, the control unit 13 causes words and messages indicating the restricted state to be displayed on the display unit 14. In addition, for example, the control unit 13 changes the display color of the temperature, humidity, and the like indicated by the air conditioning settings in the air conditioning setting image.

[0038] In addition, when the display unit 14 is an LED lamp, the control unit 13 controls turning on and off the corresponding LED lamp depending on whether or not it is in a restricted state. For example, the control unit 13 changes the lighting color of the LED lamp or the number of LED lamps to be turned on depending on whether or not it is in a restricted state.

[0039] For example, the control unit 13 causes the display unit 14 to display the restriction display until the restricted state is released. In this way, by displaying the restriction display while the air conditioning unit 11 is in a restricted state, it becomes easier for the user to recognize that the air conditioning unit 11 is in a restricted state, and it is possible to reduce meaningless operations.

[0040] Note that when the air conditioning unit 11 is in a restricted state and the reception unit 12 receives an air conditioning setting outside the restricted range, the control unit 13 may display a restriction display on the display unit 14. For example, when the air conditioning unit 11 is in a restricted state and the communication unit 121 receives an air conditioning setting transmitted from the operation terminal 20, the control unit 13 determines whether the air conditioning setting received by the communication unit 121 is within the restricted range or outside the restricted range.

[0041] Specifically, the control unit 13 refers to information indicating the restriction range contained in the restriction setting instruction stored in the memory unit 15, and determines whether the air conditioning setting received by the communication unit 121 is within the restriction range or outside the restriction range.

[0042] When the control unit 13 determines that the air conditioning setting received by the communication unit 121 is outside the restriction range, the control unit 13 causes the display unit 14 to display a restriction indication. After a predetermined period of time has elapsed since the restriction indication was displayed on the display unit 14, the control unit 13 causes the display unit 14 to erase the restriction indication.

[0043] In this way, by displaying the restriction display on display unit 14 when a signal including air conditioning settings is transmitted, the user can more easily check, for example, whether the air conditioning settings have been accepted. Also, the period during which the restriction display is displayed on display unit 14 is shortened, which reduces power consumption.

[0044] [Display restrictions on operating device] In this embodiment, a restriction display may be displayed on the operation terminal 20. For example, when the air conditioning unit 11 is in a restricted state, and the communication unit 121 receives an air conditioning setting transmitted from the operation terminal 20, the control unit 13 determines whether the air conditioning setting received by the communication unit 121 is within the restricted range or outside the restricted range.

[0045] Specifically, the control unit 13 refers to information indicating the restriction range contained in the restriction setting instruction stored in the memory unit 15, and determines whether the air conditioning setting received by the communication unit 121 is within the restriction range or outside the restriction range.

[0046] When the control unit 13 determines that the air conditioning settings received by the communication unit 121 are outside the limit range, it acquires information indicating the referenced limit range. The control unit 13 generates a limit display instruction including the acquired information indicating the limit range and an instruction to display a limit display. The communication unit 121 transmits a signal including the limit display instruction generated by the control unit 13 via the network 30 to the operation terminal 20 that sent the air conditioning settings.

[0047] The communication unit 25 of the operation terminal 20 receives a signal including a restriction display instruction transmitted from the electric appliance 10. The control unit 21 acquires the restriction display instruction included in the signal received by the communication unit 25. Based on information indicating the restriction range included in the acquired restriction display instruction and an instruction to display the restriction display, the control unit 21 causes the display unit 23 to display words, a message, etc. indicating that the electric appliance 10 is in a restricted state and an indication indicating the restriction range,.

[0048] In this way, by displaying the restriction display and the restricted range on the operation terminal 20, the user can recognize the restricted state and the restricted range at his / her fingertips.

[0049] The control unit 13 may include the air conditioning settings to be controlled in the restricted state in the restriction display instruction instead of the information indicating the restricted range. In this case, the control unit 21 of the operation terminal 20 causes the display unit 23 to display the air conditioning settings to be controlled in the restricted state.

[0050] Furthermore, in this embodiment, when the air conditioning unit 11 is in a restricted state and the communication unit 121 receives an air conditioning setting outside the restricted range transmitted from the operation terminal 20, the management terminal may be notified that an air conditioning setting outside the restricted range has been received.

[0051] For example, when the control unit 13 determines that the air conditioning setting received by the communication unit 121 is outside the restricted range, the control unit 13 generates information to the effect that the air conditioning setting outside the range has been accepted. The communication unit 121 transmits a signal including the information generated by the control unit 13 to the effect that the air conditioning setting outside the range has been accepted to the management terminal via the network 30.

[0052] Next, an example of a limit setting control method in the electrical appliance 10 of the present embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart showing an example of a limit setting control method in the electrical appliance 10 of the present embodiment. Fig. 3 shows an example of a limit display displayed on the display unit 14 when the reception unit 12 receives an air conditioning setting outside the limit range.

[0053] When the reception unit 12 receives a restriction setting instruction (Yes in step S11), the control unit 13 controls the air conditioning unit 11 to a restricted state. Specifically, the control unit 13 controls the adjustment range of the air temperature by the air conditioning unit 11 to be within the restricted range according to the restriction setting instruction (step S12). The control unit 13 waits for the reception of an air conditioning setting (step S13).

[0054] On the other hand, if the control unit 13 cannot confirm that the reception unit 12 has received a restriction setting instruction (No in step S11), it does not control the air conditioning unit 11 to the restricted state, and waits for the reception of an air conditioning setting (step S13).

[0055] When the reception unit 12 receives the air conditioning settings, the control unit 13 determines whether or not the air conditioning unit 11 is in a restricted state (step S14).

[0056] If the air conditioning unit 11 is not in a restricted state (No in step S14), the control unit 13 controls the air conditioning unit 11 in accordance with the air conditioning settings accepted by the acceptance unit 12 (step S16).

[0057] On the other hand, if the air conditioning unit 11 is in a restricted state (Yes in step S14), the control unit 13 determines whether the air conditioning setting accepted by the acceptance unit 12 is within the restricted range (step S15).

[0058] If the air conditioning setting accepted by the accepting unit 12 is within the restricted range (Yes in step S15), the control unit 13 controls the air conditioner 11 in accordance with the air conditioning setting accepted by the accepting unit 12 (step S16).

[0059] On the other hand, if the air conditioning setting accepted by the accepting unit 12 is outside the limit range (No in step S15), the control unit 13 causes the display unit 14 to display a limit indication (step S17). The control unit 13 controls the air conditioning unit 11 according to the limit range indicated by the limit setting instruction (step S18).

[0060] Next, another example of the limit setting control method in the electric appliance 10 of the present embodiment will be described with reference to Fig. 4. Fig. 4 is a flowchart showing another example of the limit setting control method in the electric appliance 10 of the present embodiment. Fig. 4 shows an example in which a limit display is displayed on the display unit 14 while the electric appliance 10 is in a restricted state.

[0061] Steps S21 and S22 shown in Fig. 4 are the same as steps S11 and S12 shown in Fig. 3. When the control unit 13 controls the air conditioning unit 11 to the restricted state (step S22), it causes the display unit 14 to display a restriction display (step S23) and waits for acceptance of air conditioning settings (step S24).

[0062] Steps S24 to S27 are the same as steps S13 to S16 shown in Fig. 3. However, if the air conditioning setting accepted by the acceptance unit 12 is outside the limit range (No in step S26), the control unit 13 controls the air conditioning unit 11 according to the limit range indicated by the limit setting instruction (step S18).

[0063] Next, a restriction display method in the air conditioning system 100 of this embodiment will be described with reference to Fig. 5. Fig. 5 is a sequence diagram showing the restriction display method in the air conditioning system 100 of this embodiment.

[0064] The operation terminal 20 transmits a restriction setting instruction to the electric device 10 (step S31).

[0065] The electric device 10 receives the restriction setting instruction and transitions to a restricted state (step S32).

[0066] The operation terminal 20 transmits the air conditioning setting that is outside the restricted range to the electrical device 10 (step S33).

[0067] The electrical device 10 determines that the air conditioning setting from the operation terminal 20 is outside the limit range (step S34), and generates a limit display instruction including information indicating the limit range and an instruction to display the limit display, and transmits the instruction to the operation terminal 20 (step S35).

[0068] The operation terminal 20 receives the restriction display instruction transmitted from the electric device 10, and displays the restriction display in accordance with the instruction to display the restriction display included in the restriction display instruction (step S36).

[0069] Furthermore, the operation terminal 20 displays the restricted range based on the information indicating the restricted range included in the restriction display instruction (step S37).

[0070] In the present embodiment, the electrical appliance 10 is an air conditioner, but is not limited thereto and may be, for example, an electric fan, an electric carpet, or the like.

[0071] The embodiments of the present invention have been described above with reference to the drawings (FIGS. 1 to 5). However, the present invention is not limited to the above embodiments, and can be implemented in various forms without departing from the spirit of the present invention. The drawings are mainly schematic illustrations of each component for ease of understanding, and the thickness, length, number, etc. of each component shown in the drawings are different from the actual ones due to the convenience of drawing. Furthermore, the materials, shapes, dimensions, etc. of each component shown in the above embodiments are merely examples and are not particularly limited, and various modifications are possible within a range that does not substantially deviate from the effects of the present invention.
