<Operation of exercise bike generator>
FIG. 6 is an example of a flowchart for explaining the operation of the exercise bike generator shown in FIG.
In the flowchart shown in FIG. 6, the subject of operation is the CPU 73.
First, the CPU 73 determines whether or not a switch for driving the electric fan 21 is pushed after completion of charging of all the storage batteries connected to the battery box 25 and the connector 41 (step S1), and a switch for driving the electric fan 21 is determined. Is determined (step S1 / Yes), it is determined whether or not a switch for driving the DC / AC inverter 67 has been pressed after all the storage batteries have been charged (step S2).
When the switch for driving the DC / AC inverter 67 is pressed (step SS2 / Yes), the CPU 73 drives only the relay 63a among the relays 63a to 63e of the switching unit 62 and starts charging the mobile phone (step) S3).

CPU 73 determines whether or not charging of the mobile phone is completed (step S5).
When the mobile phone is being charged, that is, when the charging is not completed (step S5 / No), the CPU 73 displays the remaining time until the charging is completed on the display unit 24 and continues the charging (steps S4 and S5). When the charging of the mobile phone is completed (step S5 / Yes), the charging completion is notified (step S6), and only the relay 63b among the relays 63a to 63e of the switching unit 62 is driven to start charging the nickel metal hydride storage battery. (Step S7).

CPU73 judges whether charge of the nickel metal hydride storage battery was completed (step S9).
When the charging of the nickel-metal hydride storage battery is not completed (step S9 / No), the CPU 73 displays the remaining time until charging on the display unit 24 and continues the charging (steps S8 and S9). When the charging of the nickel metal hydride storage battery is completed (step SS9 / Yes), the charging completion is notified (step S10), and only the relay 63c among the relays 63a to 63e of the switching unit 62 is driven to start charging the lead storage battery. (Step S11).

CPU73 judges whether charge of a lead storage battery was completed (Step S13).
When the lead-acid battery is being charged, that is, when the charging is not completed (step S12 / No), the CPU 73 displays the remaining time until the charging is completed on the display unit 24 and continues the charging (steps S12 and S13). When the charging of the lead storage battery is completed (step S13 / Yes), the charging completion is notified (step S14), and only the relay 63d among the relays 63a to 63e of the switching unit 62 is driven to generate the generator 53 to the fan 21. Power supply from only is started (step S15). At this time, if the drive switch of the electric fan 21 is ON, the electric fan 21 is driven to blow air toward the user of the exercise bike generator 10.

The CPU 73 starts feeding power from only the generator 53 to the DC / AC inverter 67 (step S17). At this time, an external device (for example, home appliances such as an electric kettle, coffee maker, radio, and television) can be connected to the connector 40 of the DC / AC inverter 67 and operated.
Here, the electric power feeding to the electric fan 21 and the DC / AC inverter 67 is performed not from the storage battery but only from the generator 53.

  The CPU 73 determines whether power generation is continuing (step S17). If the CPU 73 determines that power generation is continuing (step S17 / Yes), it returns to step S15, and if it is determined that power generation is not continuing, that is, power generation has stopped (step S17 / No), finish.

Here, when the switch 30 for driving the electric fan is not ON after the charging of all the storage batteries is completed (step S1 / No), the CPU 73 determines whether or not the switch 30 of the electric fan 21 is OFF (step S21).
When the switch of the fan 21 is not OFF (step S21 / No), the CPU 73 supplies power from the generator 53 to the fan 21 (step S22). When the switch of the fan 21 is OFF (step S21 / Yes), the fan 21 is supplied. Power supply to is stopped (step S23).

  Further, when the switch for driving the DC / AC inverter 67 is not pushed after the charging of all the storage batteries is completed (step S2 / No), the CPU 73 switches the switch 68 for supplying power to the DC / AC inverter 67. When is OFF, power is not supplied to the DC / AC inverter 67.

  As described above, the exercise bike generator 10 according to the present embodiment displays the time until the storage battery is fully charged on the display unit 24, so that the time until the charge is completed can be grasped. In principle, since the electric power can be supplied from the generator to the electric fan 21 and the DC / AC inverter 67 after the storage battery is completely charged, surplus electric power of the electric generator can be used effectively.

  For example, the exercise bike generator of the present application can be used for rehabilitation of patients at a rehabilitation center of a hospital, or installed in a public facility and used by an unspecified number of people.
