The storage unit 40 includes a drawer body 41 having an upward opening for entering and exiting the storage and forming a receiving space for keeping the freshness such as fish or meat vegetables, and protruding in front of the drawer body 41. It is formed to include a handle 44 that can be gripped by the user to draw the drawer body 41 from the refrigerating compartment 20.

The drawer main body 41 has a cold air inlet 42 for introducing cold air from the freezer compartment 10 passing through the middle bulkhead 30 into the inner space of the drawer main body 41 on one side wall in contact with the middle bulkhead 30. The cold air flowing into the inner space of the drawer body 41 through the cold air inlet 42 circulates through the inner space of the drawer body 41 and then passes back through the intermediate partition 30 to return to the freezing chamber 10 again. A cold air discharge port 43 through which cold air is discharged inside the drawer body 41 is formed.

Here, the cold air inlet 42 is formed at a position corresponding to the same air line as the cold air outlet 31 through which the intermediate partition 30 is formed so that the cold air of the freezer compartment 10 may pass through the intermediate partition 30. The cold air discharge port 43 has the same axis as the cold air return port formed through the intermediate partition 30 so that the cool air inside the drawer body 41 passes through the intermediate partition 30 and returns to the freezing chamber 10 again. It is formed in the position corresponding to a line.

You can do this smoothly. In addition, due to the smooth flow of cold air, the freshness of the storage stored in the accommodating part 40 may be continuously maintained.

Furthermore, if the defrost heater 51 and the defrost receiving unit 52 that can receive the defrost water is further provided, it may be more desirable to remove the frost implanted on the implant plate 50 and receive it.

Meanwhile, in the above-described embodiment, one of the plurality of storage drawers is provided with the cold air supplied to the freezer compartment. However, the storage unit may maintain the freshness of the stored product by supplying the cold air of the freezer compartment to each of the plurality of storage drawers installed in the refrigerator compartment. Of course it can.

As described above, according to the present invention, due to the temperature difference between the cold and the freezer compartment that circulates inside the storage unit and returns to the freezing chamber through the cold return port, frost is formed in the middle partition wall in which the cold return port inner region or the cold return channel is formed. By suppressing implantation, it is possible to provide a refrigerator having a smooth flow of cold air between the freezer compartment and the inside of the storage unit.

Furthermore, if the defrost heater and the defrost receiver are provided in the lower part of the implantation member, the frost formed on the implantation member can be easily removed and the defrost water from the implantation member can be easily discharged.
