Abstract

A self-propelled cleaner (1), i.e., a self-propelled electronic device, includes a temperature measurement unit (63) that measures an ambient temperature during self-propelled operation, a temperature decision unit (521) that decides whether the measured ambient temperature is equal to or more than a set value, and an abnormal temperature notification unit (522) that externally reports abnormal temperature information indicating that the measured ambient temperature is equal to or more than the set value if the measured ambient temperature is decided to be equal to or more than the set value.

Claims

1. A self-propelled electronic device with a travel driving unit, comprising:

a temperature measurement unit that measures an ambient temperature during self-propelled operation;

a temperature decision unit that decides whether the ambient temperature measured by the temperature measurement unit is equal to or more than a set value; and

an abnormal temperature notification unit that externally reports abnormal temperature information indicating that the measured ambient temperature is equal to or more than the set value if the temperature decision unit decides that the measured ambient temperature is equal to or more than the set value.

2. The self-propelled electronic device according to claim 1, further comprising:

a voice output unit,

wherein the abnormal temperature notification unit causes the voice output unit to output the abnormal temperature information as voice information.

3. The self-propelled electronic device according to claim 1, further comprising:

a data communication unit that performs data communication with an external terminal device,

wherein the abnormal temperature notification unit causes the data communication unit to transmit the abnormal temperature information to the external terminal device.

4. The self-propelled electronic device according to claim 3, transmitting, as the abnormal temperature information, information that causes the terminal device to output a voice indicating that the self-propelled electronic device is exposed to a dangerous temperature environment or information that causes the terminal device to display an image indicating that the self-propelled electronic device is exposed to a dangerous temperature environment, to the terminal device.

5. The self-propelled electronic device according to claim 1, further comprising:

a measurement control unit that decides whether a certain time has elapsed after the temperature decision unit decides that the measured temperature is equal to or more than the set value and, if the certain time has elapsed, causes the temperature measurement unit to perform temperature control again.

6. The self-propelled electronic device according to claim 1, further comprising:

a travel driving control unit that, if the temperature decision unit decides that the measured temperature is equal to or more than the set value, causes the travel driving unit to move the self-propelled electronic device to an area where the measured temperature does not exceed the set value.

7. The self-propelled electronic device according to claim 1, further comprising:

a travel driving control unit that counts the number of times the abnormal temperature notification unit has externally reported the abnormal temperature information and, if the counted number of times exceeds a set value of the reported number of times, causes the travel driving unit to move the self-propelled electronic device to an area where the measured temperature does not exceed a set value of the measured temperature.

8. The self-propelled electronic device according to claim 1, further comprising:

a cleaning function.

9. The self-propelled electronic device according to claim 1, further comprising:

an air cleaning function.

10. The self-propelled electronic device according to claim 8, further comprising:

an ion generating unit,

wherein ions generated by the ion generating unit are released together with air released from the self-propelled electronic device.
