Abstract
Provided are a method and an electronic device for detecting contamination of a filter. When a revolutions per minute (RPM) of a fan motor increases so as to exceed a target RPM, a stabilization time is detected from a time point when the RPM of the fan motor reaches the target RPM to a time point when the RPM of the fan motor is maintained within a reference RPM difference with respect to the target RPM. When it is determined that the detected stabilization time is greater than a filter replacement threshold time, a notification to replace the filter is displayed on a display.
Claims20
An electronic device comprising:
- a fan that is rotatable to suction air through a filter;
- a fan motor configured to rotate the fan;
- at least one memory storing one or more instructions;
- and
- at least one processor configured to execute the one or more instructions stored in the at least one memory to:
- when a revolutions per minute (RPM) of the fan motor increases while rotating the fan so as to exceed a target RPM, detect a stabilization time from a time point when the RPM of the fan motor reaches the target RPM to a time point when the RPM of the fan motor is maintained within a reference RPM difference with respect to the target RPM,
- determine whether the detected stabilization time is greater than a filter replacement threshold time, and
- when it is determined that the detected stabilization time is greater than the filter replacement threshold time, perform control so that a notification to replace the filter is displayed on a display.
A method of controlling an electronic device that includes a fan that is rotatable to suction air through a filter, and a fan motor configured to rotate the fan, the method comprising:
- when a revolutions per minute (RPM) of the fan motor increases while rotating the fan so as to exceed a target RPM, detecting a stabilization time from a time point when the RPM of the fan motor reaches the target RPM to a time point when the RPM of the fan motor is maintained within a reference RPM difference with respect to the target RPM;
- determining whether the detected stabilization time is greater than a filter replacement threshold time;
- and
- when it is determined that the detected stabilization time is greater than the filter replacement threshold time, performing control so that a notification to replace the filter is displayed.
