FIG. 1 is a perspective view showing a refrigerator 1 according to a first embodiment of the present invention. FIG. 2 is a vertical cross-sectional view showing the refrigerator 1 according to the first embodiment of the present invention.

As shown in FIGS. 1 and 2, the refrigerator 1 includes an outer box 2 that covers the outside and an inner box 3 that is arranged inside the outer box 2. A heat insulating wall formed by using a heat insulating material such as polyurethane foam is provided between the outer box 2 and the inner box 3.

The refrigerator 1 has a refrigerating chamber 4 at the top. The refrigerator 1 has a vegetable compartment 5 in the lower middle portion of the refrigerator compartment 4. Refrigerator 1 has a freezing chamber 6 in the lower part below the vegetable compartment 5. These chambers are partitioned and formed by a heat insulating wall.

In the refrigerator 1, a cold air circulation air passage 8 for circulating cold air from the lowermost cooler 7 to each of these chambers is formed on the back side of these chambers. The cold air circulation air passage 8 of the refrigerator 1 is formed by connecting a plurality of ducts.

<Structure of vegetable room 5>
The vegetable compartment 5 of the refrigerator 1 is partitioned above the refrigerator compartment 4 by a heat insulating wall 9, and a partition plate 10 shown in FIG. 6 described later is provided on the back side and the upper portion so as to project downward. The vegetable compartment 5 includes a cold air circulation air passage component 11 arranged on the inner side of the chamber. The cold air circulation air passage component 11 has a rectangular cover 12. A duct 13 forming a part of the cold air circulation air passage 8 is attached to the cover 12. The upper end portion 12b of the cover 12 of the cold air circulation air passage component 11 is in contact with the partition plate 10 provided in the vegetable compartment 5. As a result, the vegetable compartment 5 is closed on the back side by the cover 12, and the back wall is formed by using the cold air circulation air passage component 11.

The vegetable compartment 5 has a drawer door (not shown) that closes the opening on the front side, and a box-shaped container (not shown) that is attached to the drawer door and has an opening at the top. In the vegetable compartment 5, the containers are guided by rails 14 provided on both the left and right sides, and the containers are retractably stored.

<Structure of cold air circulation air passage component 11>
FIG. 3 is a perspective view showing the cold air circulation air passage component 11 according to the first embodiment of the present invention as viewed from the front side. FIG. 4 is a perspective view showing the cold air circulation air passage component 11 according to the first embodiment of the present invention as viewed from the back side. FIG. 5 is a vertical cross-sectional view showing the cold air circulation air passage component 11 according to the first embodiment of the present invention.

The cold air circulation air passage component 11 has a cover 12 that constitutes a back wall in the vegetable compartment 5. The cold air circulation air passage component 11 is integrated with the cover 12, and has a duct 13 that forms a part of the cold air circulation air passage 8 on the back side of the back wall from the cover 12. An outlet 15 for supplying cold air to the vegetable compartment 5 is formed in a region of the cover 12 where the duct 13 is not formed.

The cover 12 has a main body portion 12a, an upper end portion 12b, three ribs 12c shown in FIG. 6 to be described later, and four ribs 12d different from the ribs 12c. The main body portion 12a of the cover 12 constitutes the back wall in the vegetable compartment 5. The upper end portion 12b of the cover 12 is bent from the main body portion 12a of the cover 12, which constitutes the back wall of the vegetable compartment 5, to the front side of the vegetable chamber 5, as shown in FIG. 6, which will be described later.

FIG. 8 is an enlarged view showing the rib 12c of the cold air circulation air passage component 11 according to the first embodiment of the present invention.

The three ribs 12c function as auxiliary contact portions that are upper end portions 12b of the cover 12 and that expand the contact region that contacts the partition plate 10 provided in the vegetable compartment 5 above the duct 13. The number of ribs 12c may be 1 or more, and is not limited. The three ribs 12c are the upper end 12b of the cover 12 and are arranged on the left, right, and center above the duct 13, respectively.

As shown in FIG. 7, the rib 12c has the same thickness as the cover 12. As a result, it is easy to mold evenly together with the resin cover 12. As shown in FIG. 8, the rib 12c is provided with a plate surface upright on the upper surface of the upper end portion 12b. A small gap S is formed between the contact portion on the front side of the rib 12c and the partition plate 10.

As shown in FIG. 8, the rib 12c is chamfered at the inner corner of the vegetable chamber, and the corner is formed into an R shape 12c1. This prevents the cover 12 from being caught by other parts when rotating.

As shown in FIG. 8, the inner edge of the rib 12c in the vegetable compartment 5 is formed flush with the inner surface of the main body 12a forming the inner wall in the vegetable compartment 5 of the cover 12. As a result, the width from the front side to the back side is widened to the maximum to increase the strength while preventing the cover 12 from being caught by other parts when rotating.

The rib 12d that functions as an auxiliary contact portion is provided at a position other than above the duct 13 at the upper end portion 12b of the cover 12. Two of these ribs 12d are arranged on the left and right sides of the duct 13 at intervals of two.

<Installation method of cold air circulation air passage component 11>
In the cold air circulation air passage component 11, the tip of the upper end 12b of the cover 12 is brought into contact with the partition plate 10, the tip of the upper end 12b is used as a rotation fulcrum, and the opening space from the upper side to the inner side in the vegetable compartment 5 It is fitted.

FIG. 9 is an enlarged view showing a lower end portion 12e of the cold air circulation air passage component 11 according to the first embodiment of the present invention.

The ribs 12c and 12d of the upper end portion 12b of the cover 12 are fixed by being pressed by the partition plate 10. Here, even if the resin cover 12 is bent and deformed, it does not deform because the position of the duct 13 is fixed with respect to the back direction of the vegetable compartment 5. On the other hand, the bent cover 12 may be deformed to the front side of the vegetable compartment 5 which is a free space. However, the rib 12c provided above the duct 13 expands the contact area and contacts the partition plate 10. Therefore, the duct 13 is prevented from tilting toward the front side of the vegetable compartment 5.

By pressing the ribs 12c and 12d in contact with the partition plate 10 in this way, the cover 12 is fixed, and a part of the cold air circulation air passage 8 of the duct 13 is set in the correct position. That is, even if the cover 12 is deformed and tries to bend, it does not tilt toward the front side of the vegetable compartment 5. In particular, since three ribs 12c are arranged above the duct 13, the three ribs 12c come into contact with the partition plate 10 to fix the cover 12, and a part of the cold air circulation air passage 8 of the duct 13 is provided. It stays in the correct position more precisely. Therefore, it is possible to prevent a part of the cold air circulation air passage 8 of the duct 13 and a part of the cold air circulation air passage 8 of the other parts from being displaced from each other and causing cold air leakage.
