PURPOSE: An oil recovery device for a refrigerator is provided to improve the performance of an evaporator by preventing oil from flowing into the evaporator. CONSTITUTION: An oil recovery device for a refrigerator comprises a first evaporator(5), a second evaporator(6), a first connection pipe(51), a second connection pipe(61), an oil storage(8), a third evaporator(7), and a third connection pipe(72). The second evaporator is located under the first evaporator. Refrigerants exhausted from the first evaporator flow into a compressor through the first connection pipe. Refrigerants exhausted from the second evaporator pass through the first connection pipe through the second connection pipe. The oil storage is connected to the bottom of the first connection pipe and recovers oil. The third evaporator is located under the second evaporator. Refrigerants exhausted from the third evaporator pass through the first connection pipe through the third connection pipe.
