And the charger 20 is arrange | positioned on the range which can perform infrared communication with these household appliances, for example, the charger stand 301 inside the room 30. FIG. In addition, the air conditioner 32, the television 33, and the video tape recorder 34 shall each have the infrared rays light-receiving parts 35a-35c for receiving the infrared rays which the charger 20 outputs. For simplification of description, a case where the charger 20 controls the air conditioner 32 (for example, power on / off) will be described.

(Operation when set)
The operations of the mobile phone 10 and the charger 20 when the mobile phone 10 is set in the charger 20 will be described with reference to FIG.

  First, infrared information setting operation SET1, calendar information setting operation SET2, and time information setting operation SET3 by the user are reflected as control data, and stored in the terminal storage unit 13 as infrared setting information DAT1, calendar information DAT2, and time information DAT3. Shall.

  At this time, the infrared setting information DAT1 indicates that when the mobile phone 10 is set in the charger 20, the power of the air conditioner 32 is turned on, and when the mobile phone 10 is released from the charger 20, the power is turned off. Assume that settings have been written. It is assumed that the date and time for controlling the air conditioner 32 is also written in the calendar information DAT2 and the time information DAT3.

  When the mobile phone 10 is set in the charger 20 (ST11), the communication electrodes C101 and C201 are connected, the charging electrodes C102 and C202 are connected, and the charging electrodes C103 and C203 are connected. Thereby, the terminal charge detection unit 14 detects the set of the mobile phone 10 (step ST12), and then the charge detection unit 21 also detects the set of the mobile phone 10 (step ST13). That is, the terminal charge detection unit 14 and the charge detection unit 21 recognize the start of charging.

  Upon receiving a charge start signal from the terminal charge detection unit 14, the device control unit 171 controls the terminal communication unit 18 to transmit the control data in the terminal storage unit 13 to the charger 20 (step ST14). At this time, the charger communication unit 22 is in a standby state waiting for reception of control data (step ST15), and when the terminal communication unit 18 transmits a transmission start signal to the charger communication unit 22 (step ST16), The charger communication unit 22 receives a signal to start transmission from the terminal communication unit 18 and is ready to receive control data (step ST17).

  The device control unit 171 controls the terminal communication unit 18 so as to transmit the infrared setting information DAT1 in the terminal storage unit 13 because the device control unit 171 can communicate with the charger 20. The terminal communication unit 18 transmits the infrared setting information DAT1 to the charger communication unit 22 (step ST19). When the charger communication unit 22 receives the infrared setting information DAT1 from the terminal communication unit 18, the charger control unit 23 Stores the infrared setting information DAT1 in the charger storage unit 24 (step ST110).

  Subsequently, the terminal communication unit 18 transmits the calendar information DAT2 to the charger communication unit 22 (step ST111), and when the charger communication unit 22 receives the calendar information DAT2 from the terminal communication unit 18, the charger control unit 23 stores the calendar information DAT2 in the charger storage unit 24 (step ST112).

  Similarly, the terminal communication unit 18 transmits the time information DAT3 to the charger communication unit 22 (step ST113). When the charger communication unit 22 receives the time information DAT3 from the terminal communication unit 18, the charger control is performed. Unit 23 stores time information DAT3 in charger storage unit 24 (step ST114).

  After transmitting the control data, the terminal communication unit 18 transmits a signal indicating the end of transmission to the charger communication unit 22 (step ST115). The charger communication unit 22 receives a signal indicating the end of transmission from the terminal communication unit 18, and after the charger control unit 23 becomes controllable (step ST116), the terminal communication unit 18 transmits the control data. Is terminated (step ST117).

  The charger control unit 23 reads the time information DAT3 stored in the charger storage unit 24 (step ST118), and then reads the calendar information DAT2 (step ST119).

  The determination unit 231 compares the date and time counted by the RTC 25 with the dates and times of the calendar information DAT2 and the time information DAT3, and determines whether or not the air conditioner 32 needs to be controlled (step ST120). If the two dates coincide (YES), the charger control unit 23 reads the infrared setting information DAT1 stored in the charger storage unit 24 (step ST121), and the power supply of the air conditioner 32 is based on the infrared setting information DAT1. Is generated and outputted to the infrared devices 26a to 26d, and the infrared devices 26a to 26d transmit the control signals as infrared rays (step ST122).

  As a result, the infrared light receiver 35a of the air conditioner 32 receives a control signal from the infrared devices 26a to 26d, and the power supply of the air conditioner 32 is turned on.

  On the other hand, if the dates and times do not match in step ST120 (NO), the series of processing ends.

(Release behavior)
Next, operations of the mobile phone 10 and the charger 20 when the mobile phone 10 is released from the charger 20 will be described with reference to FIG.

  When the cellular phone 10 is released from the charger 20 (ST21), the connection between the communication electrodes C101 and C201 is disconnected, the connection between the charging electrodes C102 and C202 is disconnected, and the charging electrodes C103 and C203 are disconnected. The connection is broken. Thereby, the terminal charge detection unit 14 detects the release of the mobile phone 10 (step ST22), and then the charge detection unit 21 also detects the release of the mobile phone 10 (step ST23). That is, the terminal charge detection unit 14 and the charge detection unit 21 recognize the end of charging.

  After the charging of the battery 16 is completed (step ST24), the control of the air conditioner 32 (for example, switching off the power supply) is executed again. Specifically, the charger control unit 23 reads the time information DAT3 stored in the charger storage unit 24 (step ST26), and then reads the calendar information DAT2 (step ST27).

  The determination unit 231 compares the date and time counted by the RTC 25 with the date and time of the time information DAT3 and the calendar information DAT2, and determines whether or not the air conditioner 32 needs to be controlled (step ST28). If the two dates coincide (YES), the charger control unit 23 reads the infrared setting information DAT1 stored in the charger storage unit 24 (step ST29), and the power supply of the air conditioner 32 is based on the infrared setting information DAT1. Is generated and output to the infrared devices 26a to 26d, and the infrared devices 26a to 26d transmit the control signals as infrared rays (step ST210).

  As a result, the infrared light receiver 35a of the air conditioner 32 receives a control signal from the infrared devices 26a to 26d, and the power supply of the air conditioner 32 is switched off.

  On the other hand, if the dates and times do not match in step ST28 (NO), the series of processing ends.

  As described above in detail, when the mobile phone 10 is set in the charger 20, the power supply of the air conditioner 32 is turned on, and when the mobile phone 10 is released from the charger 20, the power supply of the air conditioner 32 is turned off. Switch.

  In addition to the control of the air conditioner 32, for example, when the television 35 (which may be the video tape recorder 34) shown in FIG. 4 is also controlled (for example, the power is turned on / off), the following may be performed. For example, in the infrared setting information DAT1, a setting that turns on the power of the television 35 when the mobile phone 10 is set in the charger 20 and turns off the power when the mobile phone 10 is released from the charger 20 is added. Keep it. The date and time for controlling the television 35 are additionally written in the calendar information DAT2 and the time information DAT3.

  Then, for each household electrical appliance to be controlled, when the mobile phone 10 is set, for example, the processing of steps ST120 to ST122 is repeated, and when the mobile phone 10 is released, for example, the processing of steps ST28 to ST210 may be repeated. .

  Needless to say, the battery 16 is charged before the mobile phone 10 is set in the charger 20 and released.

  In the present embodiment, after the process described with reference to FIG. 5 or FIG. 6, the charger 29 can control the home appliance alone using the schedule function. A specific example will be described with reference to FIG.

  FIG. 7 is a sequence diagram illustrating an operation example performed by the charger after the mobile phone according to the present embodiment is released.

  In the following description, after the processing when the mobile phone 10 is set is executed (steps ST11 to ST122 shown in FIG. 5), the processing when the mobile phone 10 is released is executed (shown in FIG. 6). Steps ST21 to ST1210) to be performed. That is, the charger storage unit 24 stores infrared setting information DAT1, calendar information DAT2, and time information DAT3, and the mobile phone 10 is released.

  At this time, the calendar information DAT2 and the time information DAT3 are written with a start time, an end time, a time interval, etc. for executing the schedule function. It is assumed that the infrared setting information DAT1 includes a setting for turning on the power of the air conditioner 32 when the start time is reached and turning off the power when the end time is reached.

  When the time measured by the RTC 25 reaches the start time set in the calendar information DAT2 and the time information DAT3 (step ST31), the charger control unit 23 performs steps ST118 to ST122 shown in FIG. Processing similar to that shown in steps ST26 to ST210 is executed.

  That is, the charger control unit 23 reads the time information DAT3 stored in the charger storage unit 24 (step ST31), and then reads the calendar information DAT2 (step ST32).

  The determination unit 231 compares the date and time counted by the RTC 25 with the date and time of the time information DAT3 and the calendar information DAT2, and determines whether or not the air conditioner 32 needs to be controlled (step ST34). If the two dates coincide (YES), the charger control unit 23 reads the infrared setting information DAT1 stored in the charger storage unit 24 (step ST35), and the power source of the air conditioner 32 is based on the infrared setting information DAT1. Is generated and outputted to the infrared devices 26a to 26d, and the infrared devices 26a to 26d transmit the control signals as infrared rays. (Step ST36). As a result, the power supply of the air conditioner 32 is switched on.

  On the other hand, if the dates and times do not match in step ST34 (NO), the series of processing ends.

  When the time counted by the RTC 25 reaches the end time, the above-described steps ST31 to ST36 are executed so that the power supply of the air conditioner 32 is turned off. Even when the home appliance is controlled at predetermined intervals (for example, one hour), the same processing as steps ST31 to ST36 is executed.
