It relates to a cold air flow path structure of the refrigerator configured to be discharged into the refrigerating chamber through the cold air discharge port of the side surface of the refrigerator compartment.

In general, the refrigerator discharges cold air generated by a refrigeration cycle consisting of a compressor, a condenser, an expansion valve, an evaporator, and lowers the temperature in the refrigerator to freeze or refrigerate food and the like. Top Mount-Type with R) partitioned up and down, Bottom Freezer-Type with Refrigerator compartment R and Freezer compartment F and Up and Down compartments, and Freezer compartment F And the refrigerating chamber (R) is divided into a side by side type (Side By Side-Type) divided into left and right.

Referring to the top-mounted refrigerator in which the freezer compartment F and the refrigerating compartment R are divided into upper and lower parts of the refrigerator divided into the above shapes, the following description is as follows.

As shown in FIG. 1, the top-mounted refrigerator includes: a refrigerator body (2) in which a freezer compartment and a refrigerating compartment are divided up and down by a barrier (1); A freezer compartment door (4) and a refrigerating compartment door (5) for opening and closing the refrigerator main body (2); An ice maker 20 installed inside the freezing compartment F or the freezing compartment door 4 to allow the supply water to be defrosted by the cold air discharged and supplied to the freezing compartment F; An ice bank (30) for receiving the ice extracted from the ice maker (20); Refrigeration cycle devices including a compressor, a condenser (not shown), an expansion valve (not shown), and an evaporator 8 to form a refrigeration cycle so that cold air necessary for cooling the freezing compartment F and the refrigerating compartment R may be generated. It is composed.

In particular, the freezing chamber so that the cold air generated through the evaporator 8, which takes the ambient heat among the elements of the refrigeration cycle equipment to evaporate the refrigerant in the gas phase state can be discharged to the freezing compartment (F) and the refrigerating chamber (R). The cold air supply duct 12 and the cold air discharge port 14 are formed in the inner wall (F) and the rear surface of the refrigerating chamber R. As shown in FIG.

The ice maker 20 and the ice bank 30 are components of an ice making apparatus in which ice is iced by cold air supplied from the freezing chamber F, and thus the ice maker 20 has a plurality of partition protrusions.
