Abstract:
A refrigerator comprising: a cooler; a heater unit (80) for heating the cooler; a current supply unit (105) for supplying current to the heater unit (80); a temperature measurement device (90) for measuring the temperature of the cooler; a determination unit (113) for determining whether the elapsed time of a state (in which an absolute value for a temperature difference between the measured temperature of the cooler and the melting point of ice is equal to or less than a reference temperature difference) is equal to or greater than a reference time, and for determining whether a match with a stopping condition for stopping the supply of current from the current supply unit (105) to the heater unit (80) has been achieved; and a heater control unit (114) for controlling the current supply unit (105) so as to increase the amount of heat generated by the heater unit (80) when the determination unit (113) has determined that the elapsed time is equal to or greater than the reference time, and for controlling the current supply unit (105) so as to stop the supply of current to the heater unit (80) when the determination unit (113) has determined that a match with the stopping condition has been achieved.
