The invention discloses a fresh keeping refrigerator which comprises a first chamber and a water drainage pipe arranged above the first chamber. The fresh keeping refrigerator further comprises an evaporation vessel arranged in the first chamber, and the water drainage pipe extends downwards to penetrate the top wall of the first chamber to be connected with the evaporation vessel. The evaporation effect is achieved through circulation of air in the chamber, dependency on the temperature of a compressor is avoided, the temperature in the chamber is improved, and the fresh keeping effect is achieved.
