Abstract
Disclosed is an apparatus for extracting coffee that includes an input part which receives a command for controlling an operation of the apparatus for extracting coffee; a heater which heats water supplied to a coffee flow path for extracting coffee; a temperature sensor which measures the temperature of the heater; an input voltage acquisition part which acquires an input voltage value applied to the apparatus for extracting coffee; and a control part which determines the possibility of coffee extraction by detecting the operation of the apparatus for extracting coffee, and if it is determined that there is a high possibility of coffee extraction, controls a preheating operation of the heater on the basis of the input voltage value acquired by the input voltage acquisition part and the temperature of the heater measured by the temperature sensor.
