And a cold air generating chamber 40 and a cooler 50 provided in the cold air generating chamber 40.

The refrigerating compartment 20 disposed above the refrigerator body 10 is opened and closed by two refrigerating compartment doors 21: 21a and 21b rotatably coupled to the left and right sides, and the freezing compartment 30 is connected to the freezing compartment door 31. By opening and closing. An ice making chamber 60 is provided inside the refrigerating chamber door 21a of one side, and a groove bar 70 is provided inside the refrigerating chamber door 21b of the other side. In addition, a machine room (not shown) in which a compressor (not shown), a condenser (not shown), and the like are accommodated below the refrigerator body 10.

The cold air generating chamber 40 is a separate space formed on the refrigerating chamber 20, and the upper, lower, front and rear walls 41 surrounding the cold air generating chamber 40 are made of a heat insulating material. In addition, the cold air generating chamber 40 is usually installed in the upper portion of the refrigerator body 10 in a state surrounded by a blowing agent 42 such as urethane.

In the cold air generating chamber 40, the cooler 50 installed therein cools the surroundings by heat exchange to generate cold air. The cooler 50 is circulated in the low temperature refrigerant compressed and condensed in the machine room.

The cold air generating chamber 40 communicates with the refrigerating chamber 20 and the freezing chamber 30 by a plurality of ducts, and the cold air generated in the cold air generating chamber 40 by this configuration is the refrigerating chamber 20 and the freezing chamber 30. Circulate Specifically, as illustrated in FIGS. 2 and 3, a main duct 81 is installed in the rear wall 11 of the refrigerator main body 10, and the main duct 81 has a rear cold air outlet 810. It communicates with the cold air generation chamber 40 through, and extends downward to communicate with the refrigerating chamber 20 and the freezing chamber 30 respectively. The main duct 81 is provided with dampers 811 and 812 at points communicating with the refrigerating chamber 20 and the freezing chamber 30, respectively.

Meanwhile, a blower fan 90 is installed at the cold air discharge port 810 of the cold air generating chamber 40, and the blower fan 90 is rotated forward and backward by a motor 91 that rotates forward and backward by an external power source. .

By such a configuration, the blowing fan 90 rotates to suck cold air in the cold air generating chamber 40 to transfer cold air downward along the main duct 81. In this case, the dampers 811 and 812 are selectively opened and closed to selectively supply cold air to the refrigerating chamber 20 or the freezing chamber 30.

Meanwhile, as shown in FIG. 2, a return duct 85 is installed on the rear wall 11 of the refrigerator main body 10 in which the main duct 81 is installed. The return duct 85 communicates with the cold air generating chamber 40 at the upper portion and extends downward to communicate with the refrigerating chamber 20 and the freezing chamber 30, respectively. The cold air introduced into the refrigerating chamber 20 and the freezing chamber 30 through the return duct 85 flows back into the cold air generating chamber 40 to circulate cold air.

In general, since the cold air of the low temperature has a property to move downward, it moves to the lower side without additional power. Unlike the main duct 81, the left and right ducts 82 and 83 do not have a separate blowing fan, and naturally flow into the refrigerating chamber 20 or the freezing chamber 30 by the characteristics of the cold air described above.

Referring to FIGS. 2 and 3 again, a front cold air outlet 840 is formed at the front of the cold air generating chamber 40 to communicate with the outside. A damper 841 is installed inside the front cold air outlet 840 to selectively open and close the front cold air outlet 840.

In addition, a door duct 84 is formed inside the refrigerating compartment door 21. The door duct 84 communicates with the front cold air outlet 840 in a state where the refrigerating compartment door 21 is closed. The door duct 84 is provided with a damper 842 for selectively opening and closing the door duct 84.

The dampers 841 and 842 close the front cold air discharge port 840 and the door duct 84 when the refrigerating compartment door 21 is opened, and open the refrigerating compartment door 21 when the refrigerating compartment door 21 is closed. 21) Let it flow inside.

The door duct 84 supplies cold air to the ice making chamber 60 installed inside the refrigerating chamber door 21 or supplies cold air to the home bar 70. When cold air is supplied to the door duct 84, both of the dampers 841 and 842 are opened and the blower fan 90 rotates (rotating in the opposite direction to the rotation direction when the cold air is sucked into the main duct 81). By blowing cold air forward.

As mentioned above, although the said Example about this invention was described concretely, this invention is not limited to the said Example and can be variously changed in the range which does not deviate from the technical idea of Claim.

The same applies to the refrigerator.

As described above, the present invention has the effect of increasing the front and rear width of the refrigerating compartment and the freezing compartment in the refrigerator by placing the cooler in the upper portion of the refrigerator.

In addition, the present invention is to supply the cold air by forced air in the front, rear direction in the upper cold air generating chamber. That is, by cooling the cold air to the rear can not only cool the refrigerating compartment and the freezing compartment, but also cool air can be smoothly blown from the ice maker and the home bar installed in the door by blowing the cold air forward. Therefore, the present invention has the effect of supplying cool air more efficiently.

In addition, the present invention has the effect that can be smoothly supplied by using the property that the low-temperature cold air generated in the upper cold air generating chamber flows naturally to the lower portion.
