The present invention relates to a refrigerator, and more particularly, to a refrigerator air supply structure for circulating cold air into a storage space of a refrigerator.

1 is a front view showing a refrigerator provided with a cold air supply structure according to the prior art, Figure 2 is a cross-sectional view showing the cold air supply structure shown in FIG.

As shown in the figure, the outer case 11 forms the outside of the refrigerator main body 10. In addition, the freezer compartment 15 and the refrigerating compartment 17 which are divided up and down by the inner case 13 forming the inside of the main body 10 are provided. The freezing chamber 15 and the refrigerating chamber 17 are selectively opened and closed by the freezing chamber door 15D and the refrigerating chamber door 17D, each of which has a front end pivotally installed in the main body 10 so as to rotate forward and backward.

As shown in FIG. 2, the inner case 13 corresponding to the rear surface of the refrigerating chamber 17 is provided with a pair of flow path grooves 18. The flow path groove 18 is formed by recessing a portion of the inner case 13 up and down in a predetermined width to the rear of the refrigerating chamber 17. The flow path groove 18 is for forming a flow path 25 to be described below.

Meanwhile, a cold air duct 21 is provided on the rear surface of the refrigerating chamber 17. The cold air duct 21 is for transferring the cold air heat exchanged in an evaporator (not shown) provided at the rear end of the freezing chamber 15 to the refrigerating chamber 17. The cold air duct 21 is formed in a flat polyhedral shape in which one surface in close contact with the inner case 13 is opened. In the illustrated embodiment, the cold air duct 21 is formed in a polyhedral shape having a substantially hexagonal cross section, but is not necessarily limited thereto.

The cold air duct 21 is fixed to one side of the inner case 13 corresponding to the rear surface of the refrigerating chamber 17. The cold air duct 21 may be fixed to the inner case 13 by a separate fastener (not shown) or a hook (not shown) provided in the cold air duct 21. In the state where the cold air duct 21 is fixed to the inner case 13, the flow path groove 18 is located in a longitudinal cross-sectional area adjacent to both end portions of the cold air duct 21.

In addition, a lamp installation unit 23 is provided at an upper center of the cold air duct 21. The lamp installation unit 23 is provided with a lamp (not shown) for lighting the refrigerating chamber 17.

On both sides of the space between the inner case 13 and the cold air duct 21 corresponding to both sides of the lamp mounting portion 23, a pair of flow paths 25 are provided to extend vertically. At this time, the flow path 25 is substantially formed by both inner end portions of the flow path groove 18 and the cold air duct 21. The flow path 25 serves as a passage through which cold air heat exchanged in the evaporator flows.

A plurality of cold air discharge ports 27 are provided at both ends of the front surface of the cold air duct 21. The cold air discharge ports 27 communicate with the flow channels 25, respectively, and serve as outlets through which cold air flowing through the flow channels 25 is discharged to the refrigerating chamber 17.

In addition, an insulation member 29 is provided inside the flow path 25, that is, between the inner case 13 and the cold air duct 21. The insulation member 29 serves to block heat exchange between the refrigerating chamber 17 and the cold air flowing through the flow path 25, and at the same time, the cold air flowing through the flow path flows through the inner case 13 and the cold air duct ( 21) It prevents the phenomenon of leakage to the outside through the space between. The insulation member 29 is provided to surround the entirety of the flow path 25 except for one side of the flow path 25 in communication with the cold air discharge port 27. That is, the cold air heat exchanged in the evaporator may be said to flow inside the insulation member 29.

Unexplained reference numerals denote thermal insulation layers. The heat insulation layer 14 is provided between the outer case 11 and the inner case 13 to block heat exchange between the freezing compartment 15 or the refrigerating compartment 17 and the indoor space where the refrigerator is installed.

However, the cold air supply structure for a refrigerator according to the prior art has the following problems.

As described above, the flow path 25 is formed by the inner case 13 and the cold air duct 21. Therefore, since the cold air duct 21 is separately manufactured to supply the cold air heat-exchanged in the evaporator to the refrigerating chamber 17, there is a disadvantage that the product is complicated.

In addition, a gap may occur between the inner case 13 and the cold air duct 21 due to a dimension error or a work tolerance of the inner case 13 or the cold air duct 21. Therefore, the cold air flowing through the flow path 25 is not discharged in a predetermined direction through the cold air discharge port 27 and leaks to the outside, that is, the refrigerating chamber 17 through such a gap, so that the cold air is evenly distributed in the refrigerating chamber 17. There may be a risk of not supply.
