In some embodiments, a thawing switch 224 for controlling the start or stop of a thawing program may be disposed on any one of compartment doors. The radio frequency generation module 130 may be configured to: start to work when the thawing switch 224 is turned on, and stop working when the thawing switch 224 is turned off. In a thawing process, a user can terminate the thawing program by turning off the thawing switch 224. A buzzer (not shown) may also be disposed on at least one compartment door and is configured to prompt the user that the object to be processed is thawed. The buzzer may be configured to: start to work when the detection module 150 determines that the object to be processed is thawed (the change rate of the dielectric coefficient of the object to be processed decreases to be less than or equal to the second preset threshold), and stop working when the object to be processed is taken out of the thawing chamber 114. In some exemplary embodiments, the refrigeration system of the refrigerator 10 can be configured to stop providing a cooling capacity for the containing space provided with the thawing device 100 when the thawing switch 224 is turned on; when the defrosting switch 224 is turned off, the refrigeration system of the refrigerator 10 can be controlled to provide the cooling capacity for the containing space provided with the thawing device 100 (i.e., an original cooling program for operating the refrigerator 10) to reduce the influence of the refrigeration system of the refrigerator 10 on the temperature of the thawing chamber 114 when the thawing device 100 thaws the object to be processed. The refrigeration system of the refrigerator 10 may include a compressor, a condenser, a capillary, and an evaporator for providing a cooling capacity.
