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 including a travel drive, a surface cleaner, and an air cleaner, comprising:

a temperature measurement sensor that measures an ambient temperature during a time of self-propelled operation while surface cleaning or air cleaning;

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

abnormal temperature notification circuitry 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 circuitry decides that the measured ambient temperature is equal to or more than the set value; and

travel driving control circuitry that controls the travel drive to move the self-propelled electronic device in a predetermined direction;

wherein

when the temperature decision circuitry decides during the time of self-propelled operation that the ambient temperature measured by the temperature measurement sensor is equal to or more than the set value, the travel driving control circuitry controls the travel drive to move the self-propelled electronic device to an area where the ambient temperature measured by the temperature measurement sensor is not equal to or more than the set value.

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

a voice output speaker, wherein

the abnormal temperature notification circuitry causes the voice output speaker to output the abnormal temperature information as voice information.

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

data communication circuitry that performs data communication with an external terminal device, wherein

the abnormal temperature notification circuitry causes the data communication circuitry 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:

measurement control circuitry that decides whether a certain time has elapsed after the temperature decision circuitry 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 circuitry to perform temperature control again.

6. The self-propelled electronic device according to claim 1, wherein

the travel driving control circuitry counts the number of times the abnormal temperature notification circuitry 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 drive to move the self-propelled electronic device to the area where the measured temperature does not exceed the set value of the measured temperature.

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

an ion generator, wherein

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