Abstract
A refrigerator having a thawing device. The thawing device includes: a cavity, a device door, a radio frequency generator module, an upper electrode plate and a lower electrode plate, and a detection module, configured to detect an incident wave signal and a reflected wave signal of an electrical connection wire connecting the radio frequency generation module to the upper electrode plate, and calculate a load impedance of the radio frequency generation module according to a voltage and a current of the incident wave signal and a voltage and a current of the reflected wave signal to determine the thawing progress of the object to be processed.
