Abstract (en)
[origin: EP4148356A1] The present disclosure relates to a refrigerator. The refrigerator according to one embodiment of the present disclosure comprises: an evaporator; a defrosting heater; a temperature sensor; and a controller to control the defrosting heater. The controller is configured to: in response to a defrosting operation starting time arriving, perform a defrosting operation mode including a pre-defrosting cooling mode, a heater operation mode and a post-defrosting cooling mode; perform a continuous operation mode, in which the defrosting heater is continuously on; and when a temperature change rate sequentially increases, decreases and increases again, perform a pulse operation mode, in which the defrosting heater is repeatedly turned on and off. Accordingly, defrosting efficiency may be improved, and power consumption may be reduced.
