Can be maintained.

When the refrigerator is operated in this state, the cold air of the first cold air passage 13 flows into the second cold air passage 23a of the connecting shaft 23 and is discharged through the cold air outlets 23b around the connecting shaft 23. The cold air is discharged in the longitudinal direction of both body portions 21a and 22a through discharge guide grooves 26 provided in the shaft coupling portions 25a, 25b, 25c and 25d of the shelf 20. That is, since the discharge guide groove 26 provided in the shaft coupling portions 25a, 25b, 25c, and 25d faces the longitudinal direction of the body portions 21a and 22a, the cold air of the second cold air flow passage 23a of the connecting shaft 23 is formed. Is discharged in the direction of both side walls of the storage chamber (11). In addition, since the discharge guide groove 26 is located below the body parts 21a and 22a, the cool air is discharged toward the lower part of the body parts 21a and 22a. Therefore, the cold air discharged from the discharge guide groove 26 may be supplied in a shower manner toward the storage placed on the lower shelf, and formed in the body parts 21a and 22a and the extension parts 21b and 22b of the shelf 20. Through the plurality of through holes 31 can also be supplied to the storage of the upper portion of the shelf (20). In this case, since the cold air discharged from the discharge guide groove 26 is not directly injected toward the storage material, the cold air may be prevented from being excessively cooled, and the cold air is stored through the through holes 31 of the shelf 20. ), So that the cooling of the entire storage compartment (11) can be evenly distributed.

On the other hand, when the bulk storage in the storage compartment 11, the first shelf 21 or the second shelf 22 can be used in the folded state. That is, as shown in FIG. 5, it can be used in a state where the second shelf portion 22 is bent downward while the extension portion 22b of the second shelf portion 22 is pushed toward the body portion 22a. . At this time, the storage can be stored on the upper part of the first shelf part 21, and the space where the second shelf part 22 was located (the right side of the storage compartment) becomes empty so that it can store the high or bulky storage item. Can be. In this case, the cool air of the second cold air flow passage 23a of the connecting shaft 23 is discharged downward in the direction of refraction of the second shelf part 22, and the cold air passes through the holes 31 of the second shelf part 22. Because it is distributed to both sides through), it is possible to evenly supply cold air to the position adjacent to the stores.

FIG. 6 illustrates a case in which the shelf 20 is mounted upside down while the second shelf portion 22 of the shelf 20 is folded. At this time, the storage can be placed on the upper part of the first shelf part 21, and the cold air discharged toward the second shelf part 22 from the second cold air passage 23a can be guided upward. In addition, an empty space on the right side of the shelf 20 may store a bulky storage.

FIG. 7 illustrates a case in which the shelf 20 is used as a guide means for guiding cold air without using the shelf 20 for loading a stored object. At this time, both the 1st shelf part 21 and the 2nd shelf part 22 are used in the state folded down. At this time, the cold air of the second cold air flow passage (23a) of the connecting shaft 23 is discharged downward, the plurality of through holes formed in the body portion (21a, 22a) and the extension portion (21b, 22b) of the shelf (20). It is distributed and supplied in both directions of the shelf 20 through the field 31. That is, at this time, the shelf 20 forms a partition between the stores, and serves to guide cold air between the stores. Accordingly, the user can induce more cold air to be supplied to a specific space of the storage compartment 11 by folding the shelf 20 in such a form and installing the shelf 20 at a desired position inside the storage compartment 11.

As described above in detail, the refrigerator according to the present invention can guide the supply of cold air through the connecting shaft of the shelf, and since the cold air guided through the connecting shaft is discharged in the longitudinal direction of the first and second shelf parts, While inducing even distribution of cold air therein, there is an effect that cold air is not directly injected into the storages to prevent overcooling of the storage.

In addition, the present invention can fold or unfold the first and second shelf parts of the shelf, and because the width of the shelf can be adjusted, there is an effect that can effectively use the storage space, the discharge direction of the cold air by folding or unfolding the shelf Since it can be adjusted to have the effect that the user can be supplied to the cold air in the desired direction.
