The invention provides a refrigerator. The refrigerator comprises an air flue and a temperature change chamber. The air flue is provided with an air door, the temperature change chamber is connected with the air door, a heater assembly is arranged in the temperature change chamber, and the heater assembly comprises a heater and a fan. When the air door is opened, the heater assembly does not work, and the temperature change chamber can be cooled by the air flue; when the air door is closed, the heater assembly works, and the temperature change chamber can be heated by the heater assembly. According to the technical scheme, the cooling capacity entering the temperature change chamber from the air flue can be adjusted by adjusting the size of an opening of the air door; meanwhile, the temperature of the inside of the temperature change chamber can rise by adjusting the working condition of the heater and the working condition of the fan, the fan in the temperature change chamber can increase the ventilation speed of air around the heater, hence, the heating efficiency of the heater can be improved, the adjusting range of the temperature in the temperature change chamber can be widened, and accordingly the functional requirements of users on the various aspects of unfreezing, leavening dough, heating milk, heating facial masks and the like can be met.
