The supply duct holder 132 is formed to have a shape in which a plurality of straight lines are coupled as shown, and the supply duct insertion hole 132 ′ vertically penetrated is formed in the supply duct holder 132. . Therefore, the supply duct 120 'is inserted into and fixed to the supply duct insertion hole 132'.

The discharge duct holder 134 has a shape in which a plurality of straight lines are coupled, as in the supply duct holder 132 described above, and the discharge duct insertion hole 134 ′ vertically penetrated inside the discharge duct holder 134. Is formed. Accordingly, the discharge duct 120 ″ is inserted into and fixed to the discharge duct insertion hole 134 ′.

The connecting rib 136 connects the lower end (in FIGS. 4 and 5) of the supply duct holder 132 and the upper end (in FIGS. 4 and 5) of the discharge duct holder 134. The side ribs 138 are formed symmetrically on both sides of the discharge duct holder 134 and the supply duct holder 132 so that the cold air duct 120 is positioned at the center of the wall surface of the refrigerating chamber 200. do.

In more detail, the side ribs 138 are formed at both sides of the discharge duct holder 134 and the supply duct holder 132 with a predetermined length, and an inner case having an end portion forming a wall surface of the refrigerating chamber 200. Installed in contact with (I) and the outer case (O).

In addition, the side ribs 138 formed on both sides of the discharge duct holder 134 and the supply duct holder 132 are preferably formed to have the same size. As such, the lengths of the two side ribs 138 are equal to each other at the same distance from the inner case I and the outer case O forming the inner wall and the outer wall of the refrigerating chamber 200, as shown in FIG. This is to allow the cold air duct 120 to be positioned. That is, to guide the cold air duct 120 to be positioned at the center of the inner case I and the outer case O.

As described above, when the cold air duct 120 is located at the center portion between the inner case I and the outer case O, the foam liquid L filled between the inner case I and the outer case O may be formed. The flow is smooth. That is, since the distance between the cold air duct 120 and the inner case (I) or the outer case (O) is kept constant, the foam liquid between the cold air duct 120 and the inner case (I) and the outer case (O) (L) is sufficiently filled.

Hereinafter, the operation of the refrigerator according to the present invention having the configuration as described above will be described.

When power is applied from the outside to operate the refrigerator, the refrigerating chamber 200 and the freezing chamber 300 maintain a set low temperature state by a refrigerating cycle.

The ice is made in the ice making chamber 220, and part of the cold air supplied to the freezing chamber 300 is used in the ice making chamber 220. More specifically, the evaporator (not shown) installed at the rear side of the freezing chamber 300 absorbs external heat to evaporate the internal refrigerant. Therefore, the air outside the evaporator is cooled and supplied into the freezing compartment 300.

Meanwhile, a part of the cold air supplied to the freezing chamber 300 by the cold air supply means 400 is also supplied to the ice making chamber 220. That is, the cold air forcedly flowed by the cold air supply means 400 flows into the ice making chamber 220 through the inside of the barrier 110 and the supply duct 120 '. Therefore, ice is produced in the ice making chamber 220.

Next, the cold air used to manufacture the ice in the ice making chamber 220 is relatively elevated in temperature, and then returned to the freezing chamber 300 through the discharge duct 120 ″, namely, the ice making chamber 220. Air introduced into the main body 100 through the door outlet 232 and the main body inlet 124 is returned to the rear side of the freezing chamber 300 through the discharge duct 120 ". This air is again cooled by an evaporator (not shown) and supplied to the ice making chamber 220 as described above.

On the other hand, since the cold air duct 120 is provided with a guide rib 121 and the duct holder means 130, when the cold air duct 120 is installed inside the wall surface of the refrigerating chamber 200 and the inner case (I) and Maintain a constant distance from the outer case (O).

That is, the guide rib 121 is formed in the connection duct portions 120'b and 120 "b constituting the cold air duct 120, so that the cold air duct 120 is positioned at the center of the inside of the refrigerating chamber 200 wall. In addition, the duct holder means 130 is provided on the outside of the main duct (120 'a, 120 "a) so that the cold air duct 120 is installed on the inside of the refrigerating chamber 200 wall surface while the flow This is to be prevented.

In more detail, the side ribs 138 guide the supply duct 120 'and the discharge duct 120 " to be located at the center of the wall of the refrigerating chamber 200, and prevent the left and right flows. The rib 136 serves to allow the supply duct 120 'and the discharge duct 120 "to be integrally connected to each other so that no flow occurs between them.

The scope of the present invention is not limited to the above embodiments, and many other modifications based on the present invention will be possible to those skilled in the art within the above technical scope.

In the refrigerator according to the present invention as described above in detail, a cold air duct for guiding cold air is formed inside the main body to supply a part of the cold air supplied to the freezing compartment to the ice making chamber. Therefore, there is no need for a separate device for ice production, there is an advantage that the cold air is efficiently utilized.

In addition, the present invention is provided with a duct holder means for the cold air duct installed on the wall surface of the refrigerating chamber to be positioned in place. Therefore, since the cold air duct is spaced apart from the inner case and the outer case forming the wall surface of the refrigerating chamber by a predetermined distance, there is an effect that the flow of the foam liquid filled in the wall surface of the refrigerating chamber is smooth.

In addition, since the duct holder means prevents the flow of the cold air duct and is fixed at the proper position, the flow of the foam liquid filled in the wall of the refrigerating chamber is smooth, so that the filling liquid is filled more completely. Therefore, since the cold air duct maintains a predetermined distance from inside and outside the refrigerating chamber, there is an advantage that the heat insulation effect is improved. That is, there is an advantage that the heat loss of the cold air flowing through the cold air duct is prevented.
