Abstract
A home appliance is provided. The home appliance includes a motor configured to execute a predetermined function of the home appliance, and a processor configured to determine an upper limit of noise of the home appliance based on ambient noise information of the home appliance and control a driving speed of the motor to have magnitude of noise of the home appliance equal to or less than the upper limit of the noise.
Claims16
A home appliance comprising:
- a motor configured to execute a predetermined function of the home appliance;
- an accelerometer configured to generate acceleration information by measuring acceleration of the motor;
- and
- at least one processor configured to:
- determine an upper limit of noise of the home appliance based on ambient noise information,
- control a driving speed of the motor to have magnitude of noise of the home appliance equal to or less than the upper limit of the noise,
- redetermine the upper limit of the noise during a user's absence or base d on a predicted noise information of the home appliance, and
- control the driving speed of the motor using the redetermined upper limit of the noise,
- wherein the processor is further configured to:
- extract an operation frequency of the motor using the acceleration information,
- generate reference data having a predetermined size and phase using the extracted operation frequency,
- generate noise information of the home appliance using the reference data and a noise estimation algorithm, and
- control the driving speed of the motor using the noise information and the upper limit of the noise of the home appliance.
