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.

Refrigerator

A thawing method for a thawing device includes: generating, by a radio frequency generation module, a radio frequency signal in a frequency range of 40 to 42 MHz; obtaining the radio frequency signal; and generating, by an upper electrode plate and a lower electrode plate, radio frequency waves of corresponding frequency in a thawing chamber according to the radio frequency signal, and thawing an object to be processed in the thawing chamber. Radio frequency waves using the above frequency range have shorter thawing time, higher temperature-uniformity and lower juice loss rate than radio frequency waves of other frequencies.

Thawing method for thawing device

A refrigerator has a thawing device. The thawing device includes a cylinder, having a thawing chamber with a forward opening; a device door; and a radio frequency generation module, upper and lower electrode plates electrically connected thereto generating radio frequency waves in the thawing chamber; and at least one temperature sensor is disposed on the inner wall of the thawing chamber and configured to sense the temperature of an object to be processed, thereby adjusting the power of the radio frequency generaton module to prevent the object to be processed from being excessively thawed.

A thawing method for a thawing device includes: generating a radio frequency signal; acquiring the radio frequency signal; an upper electrode plate and a lower electrode plate of the thawing chamber generating, according to the radio frequency signal, radio frequency waves having a corresponding frequency in a thawing chamber and thawing an object to be processed, obtaining voltages and currents of the incident wave signal and reflected wave signal, and determining a thawing progress of the object to be processed.
