Abstract:
1. A cooker comprising: a cooking chamber in which food is cooked; a temperature sensor detects the temperature of the cooking chamber; a first heat source and a plurality of second heat sources provide heat to heat food in the cooking chamber; an input unit capable of receiving a driving temperatures or driving levels for the first and second heat sources, the driving temperatures are user's desired temperatures, and the driving levels correspond to preset driving temperatures; and a controller controls the first and second heat sources, and the controller is capable of detecting operation times of the first and second heat sources; wherein the controller drives the first heat source at a maximum driving level thereof and drives the second heat source at an input driving level for the second heat source that the input unit has received, until the cooking chamber reaches a preset reference temperature of the cooking chamber; if the temperature sensor detects that the cooking chamber reaches the reference temperature of the cooking chamber, the controller drives the first heat source at a preset driving level of the first heat source, and drives the second heat source at a first preset driving level of the second heat source for a first preset time; and if the first preset time elapses, the controller drives the second heat source at a second preset driving level for a second preset time.
