The invention provides a refrigerator. The refrigerator comprises an inner container, an air flue, an evaporator and a draught fan; a storage chamber is limited in the inner container, the air flue extends in the inner container from bottom to top along the rear wall of the inner container, the evaporator is arranged on the outer side of the rear wall of the inner container, and is configured to indirectly cool air in the air flue, the draught fan is arranged in the air flue and located on the lower portion of the air flue, and is configured to promote air, cooled by the evaporator, in the airflue to flow into the storage chamber. According to the refrigerator, the draught fan is arranged on the lower portion of the air flue, the evaporator is arranged on the outer side of the rear wall of the inner container, when wet air passes through the refrigeration area of the evaporator through the air flue, the wet air exchanges heat with the face of the rear wall of the inner container, dueto the fact that the temperature of the face of the rear wall of the inner container is higher than the temperature of the evaporator, the frost quantity of wet air is reduced, it is ensured that muchwater steam is brought into the storage chamber, the phenomenon that most part of the water steam is frozen by the evaporator and forms frost is avoided, the humidity of the storage chamber is improved, humidity of the food in the storage chamber can be conveniently stored, and food can be prevented from being air dried.
