Refrigerator

The invention provides a refrigerator which comprises an unfreezing chamber, a temperature sensor is arranged in the unfreezing chamber, and the unfreezing chamber is configured as follows: after an object is put into the unfreezing chamber, if a heating instruction is not received within a certain period of time, the temperature of the object is continuously monitored; if it is found that the temperature change of the object accords with the heat balance trend between the object and the unfreezing chamber, after the temperature of the object reaches a preset first temperature, the temperature of the unfreezing chamber is adjusted and maintained within a certain range above and below a preset second temperature till the object is taken out. According to the invention, food can be prevented from being over-thawed or not-thawed through a method of identifying the temperature and setting the thawing threshold value; or for food which is taken out of the freezing chamber and placed in the refrigerating chamber to
