The present invention relates to a cold air circulation device of a refrigerator, and more particularly, to a cold air circulation device of the refrigerator so as to simplify the configuration by circulating cold air toward the refrigerating compartment by directly forming a cold air passage in the rear of the freezer compartment.

Generally, the refrigerator is divided into a freezer compartment 1 and a refrigerating compartment 2 filled with a heat insulating material 3b between the inner and outer wounds 3 and 3a, as shown in FIGS. 1 and 2. The freezer compartment 1 is provided with an evaporator 4 constituting a refrigeration cycle device so that the air inside the freezer compartment and the refrigerator compartment compartment 1 is cooled by cold air. Such cold air is circulated into the freezer compartment 1 along the discharge port 1a formed on the rear side of the freezer compartment 1 and also circulated into the refrigerator compartment 2 along the cold air passage 6 of the freezer compartment 1.

The cold air passage 6 is formed on a separately manufactured cover 5 and the cover 5 is attached to the back of the inner box 3 on the freezing chamber 1 side with a tape 5a in the manufacturing process of the refrigerator. And the lower end of the discharge port (2a) formed in the upper side of the refrigerating chamber (2) and the cold air passage (6) is connected by the connector (8) so that the cold air is circulated into the refrigerating chamber (2).

In the conventional cold air circulation system configured as described above, the cold air circulating inside the freezing and refrigerating chamber 1 and 2 is recovered by the circulation fan 4a toward the evaporator 4, and then cooled again, and then the freezing and refrigerating chamber 1 and 2 ) Is circulated inside. That is, the cold air passing through the evaporator 4 is circulated into the freezing chamber 1 along the discharge port 1a, and some of the cold air flows downward along the cold air passage 6, and then along the connection port 8 and the discharge port 2a. 2) Circulated inside

However, there is a need to prepare a separate cover 5 to circulate the cold air toward the refrigerating compartment 2 and then attach it to the inner box 3 behind the freezing compartment 1 using the tape 5a. In addition, the cold air passage (6) formed in the cover (5) is attached to the insulating plate (7) to prevent freezing due to the temperature difference inside the freezer compartment 1, there is a problem such as complicated configuration.

The present invention was developed in view of the conventional problems, and an object thereof is to provide a cold air circulation device of a refrigerator which simplifies the configuration by directly forming a cold air passage on the inner side of the freezer compartment and connecting the freezer compartment and the refrigerating compartment to each other by a duct. Is in.

In order to achieve the above object, the present invention provides a freezing and refrigerating chamber in which insulation is filled between inner and outer wounds; An evaporator installed at the rear of the freezer compartment; A cold air passage integrally formed on the inner side of the freezing compartment toward the refrigerating compartment; And a duct connecting the lower end of the cold air passage and the discharge port formed on the inner side of the refrigerating chamber side.

Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings.

3 is a side cross-sectional view of the present invention refrigerator. The refrigerator of the present invention is divided into a freezer compartment 10 and a refrigerating compartment 11, and the heat insulating material 15 is filled between the inner and outer wounds 13 and 14 constituting them, and the inside is insulated. In addition, the evaporator 12 is installed at the rear of the freezer compartment 10 so that the cold air circulated into the freezer and refrigerating compartment 10 and 11 is cooled and partitions the freezer and refrigerating compartment 10 and 11. It is cooled while being circulated again toward the evaporator 12 along the recovery passage 17.

The cold air is circulated by the circulation fan 12a installed above the evaporator 12. The cold air is discharged into the freezer compartment 10 along the discharge port 10a in front of the circulation fan 12a, and some of the cold air is stored in the freezer compartment 10. It is circulated into the refrigerating chamber 11 along the cold air passage 20 formed in the rear inner box 13. The cold air passage 20 is formed directly on the inner phase 13, and the heat insulation plate 21 is covered on the upper portion of the cold air passage 20. The heat insulating plate 21 insulates the evaporator 12 to prevent freezing of the cold air passage 20.

In addition, the discharge port 11a formed on the lower end of the cold air passage 20 and the upper side of the inner phase 13 toward the refrigerating chamber 11 is connected to the duct 22. In addition, the discharge port 11a is connected to the distribution plate 11b formed in the inner box 13 so that cold air is distributed and discharged into the refrigerating chamber 11 along the distribution plate 11b.

The present invention configured as described above is simplified in configuration as the cold air passage 20 is integrally formed on the inner box 13 of the freezer compartment 10 side. In addition, since the open portion of the cold air passage 20 is covered by the heat insulating plate 21 such as Schiropol, it is not directly exposed toward the evaporator 12. Thus, freezing of the passage due to subcooling of the evaporator 12 is prevented. The discharge ports 11a formed in the lower end of the cold air passage 20 and the inner phase 13 on the refrigerating chamber 11 side are connected to each other by the duct 22 so that the cold air is circulated toward the refrigerating chamber.

Referring to the cold air circulation process of the present invention in detail as follows. The cold air passing through the evaporator 12 is blown toward the discharge port 10a by the circulation fan 12a and then circulated into the freezer compartment 10. In this process, the stored food is frozen and the cold air circulated into the freezer compartment 10 is circulated again to the evaporator 12 along the recovery passage 17 formed in the diaphragm 16.

In addition, a portion of the cold air heat exchanged through the evaporator 12 is blown toward the cold air passage 20 formed behind the inner bed 13 and then circulated into the refrigerating chamber 11 along the lower duct 22. In this process, the food stored in the refrigerating chamber 11 is refrigerated at a predetermined temperature, and the refrigerated cold air is recycled toward the mid-term 12 along the recovery passage 17 formed in the diaphragm 16.

As described above, according to the present invention, a cold air passage is directly formed on the inner side of the rear of the freezer compartment and connected to the refrigerating chamber, so that a separate cover having a cold air passage is not required, and the cold air passage is blocked from the evaporator by an insulating plate. Freezing is suppressed. In addition, the lower part of the cold passage and the refrigerating chamber is directly connected by the duct has an effect such as improved assembly.
