First Claim
1. A home appliance comprising:
- an input unit including a plurality of buttons;
a driver to drive a load;
a power supply to convert AC power supplied from an outside of the home appliance, and to receive DC power during interruption of electric power, wherein the power supply includes;
an AC power sensor to sense the AC power that is externally received, anda DC power sensor to sense the DC power supplied upon interruption of electric power;
a communication unit to receive information about interruption of electric power, kind and level of backup power supplied upon interruption of electric power, or supply duration of the backup power; and
a controller configured to;
(1) perform a control operation to supply first electric power based on the supplied AC power to the load in accordance with a normal operation mode when no interruption of electric power occurs,(2) perform a control operation to supply second electric power based on the supplied DC power to the load in accordance with the normal operation mode when no interruption of electric power occurs, and(3) perform a control operation to supply third electric power based on the supplied DC power to the load in accordance with a power saving mode upon interruption of electric power, wherein the first electric power has a higher level than the second electric power, and the third electric power has a lower level than the second electric power,wherein the controller is configured to;
when interruption of electric power occurs, activate a button associated with the power saving mode and a power button, from among the plurality of buttons,when the power saving mode operates during interruption of electric power, activate a power saving mode release button, andvary operation mode or operation time of the driver of the home appliance upon interruption of electric power, based on the information about interruption of electric power, kind and level of backup power supplied upon interruption of electric power, or supply duration of the backup power.
