The present invention relates to a cold air duct structure in which a cold air discharge into the refrigerating chamber is uniformly made throughout the refrigerating chamber in the refrigerator, and in particular, a cold air duct is provided on a shelf guide that supports the refrigerator compartment shelf to discharge cold air through the cold air duct. It relates to a structure of a refrigerator cold air duct of a refrigerator to be supplied.

In the conventional refrigerators, the cold air generated from the cooler is discharged and supplied into the refrigerating chamber only through the cold air ducts extending up and down in the center of the rear wall of the refrigerating compartment. Significant temperature deviations occur in the liver, and thus, the refrigerated storage state of the food in the refrigerator compartment is difficult to be uniform throughout the inside of the refrigerator compartment.

The present invention has been devised in view of such a conventional problem, and its purpose is to ensure that the cold air discharged into the refrigerating compartment is discharged as uniformly as possible throughout the refrigerating compartment without being discharged unbiasedly. It is to provide a refrigerator refrigerator cold air duct structure of a more improved refrigerator that can lead to a refrigerator storage condition.

According to the present invention, the first cooling duct is installed horizontally above the rear wall of the refrigerating compartment and is connected to both ends of the first cold duct, and is vertically installed along both edges of the rear wall of the refrigerating compartment. A plurality of second cold air ducts extending and arranged inside the shelf guides provided on both side wall portions of the refrigerating chamber, and the rear ends thereof are respectively communicated with the second cold air ducts, and are arranged at regular intervals along the length direction of the shelf guide. It is achieved by providing a cold air duct structure comprising a third cold air duct each of the cold air discharge holes of the.

Hereinafter, the present invention will be described in more detail based on the embodiments illustrated in the accompanying drawings.

1 to 3 show one possible example of the cold air duct structure according to the present invention, wherein reference numeral 10 denotes a refrigerating chamber of a refrigerator according to the present invention, 11 a rear wall of the refrigerating chamber 10, and 12 a refrigerating chamber 10 The left and right sidewalls of) are respectively shown. According to the present invention, the first cold air duct 13 into which the circulation cold air toward the refrigerating compartment 10 is introduced among the cold air generated from the cooler (or evaporator) not shown here on the rear wall 11 of the refrigerating compartment 10 It is installed horizontally. Left and right ends of the first cold air duct 13 are respectively provided to the second cold air ducts 20 extending in the vertical direction at corners where the rear wall 11 and the side walls 12 of the refrigerating chamber 10 meet. Cold air introduced into the first cold air duct 13 in communication with each other is distributed to these second cold air ducts 20. On both sidewalls 12 of the refrigerating compartment 10, a plurality of sets of shelf guides 30 for the refrigerating compartment shelves are provided. Each shelf guide 30 has a shelf as shown in FIGS. A second cold air duct 32 having a plurality of cold air discharge holes 33 arranged at regular intervals along the longitudinal direction of the guide 30 is provided, and the rear end of each of the third cold air ducts 32 is described above. Each of the second cold air duct 20 is installed in communication with each other, and the cold air from the second cold air duct 20 flows into each of the third cold air ducts 32 and then through the cold air discharge holes 33. It is to be discharged to the inside. Here, the cold air discharge holes 21 as shown in the example shown in FIG. 1 are also provided in each of the second ducts 20 so that a part of the cold air introduced into the second cold air ducts 20 It is also discharged from both corners of the rear of the refrigerating chamber 20 through the cold air discharge holes 21, so that the cold air is discharged evenly supplied almost all over the inside of the refrigerating chamber 20.

The shelf guide 30 may be attached to the side wall 12 of the refrigerating compartment 10 by means such as, for example, a screw 34, and the shelf 5 may be fitted to the top of each shelf guide 30. Guide grooves 31 are provided. In each of the shelf guides 30, the heat insulating material 40 is disposed above and below the third cold air duct 32, and the surface of the shelf guide 30 is formed by cold air flowing inside the third cold air duct 32. Do not allow dew or frost to occur.

The present invention configured as described above is installed by inserting the shelf 50 on each shelf guide 30 and operating the refrigerator in a state in which the refrigerated foods are stored on the shelf 50, and generated from the cooler of the refrigerator. The circulating cold air into the refrigerating compartment 10 of the cold air is first introduced into the first cold air duct 13, and the cold air is distributed to the second cold air ducts 20 connected to both ends of the first cold air duct 13. And some of them are discharged into the refrigerating chamber 10 through the cold air discharge holes 21 on the second cold air duct 20, and the remaining cold air is respectively rear end of the second cold air duct 20. After the distribution flows into the third cold air duct 32 inside the shelf guide 30 is installed, through the cold air discharge hole 33 of each side of the third cold air duct 32, the lower side of each shelf 50 Discharged into the refrigerating chamber 10 from the Uniform cold air discharge is made almost all over.

Therefore, the present invention has a new useful effect that can be freshly refrigerated at a uniform temperature as a whole as a whole, the food stored in the refrigerating chamber by the configuration, action as described above.
