[0014]

Next, the operation of the inner box structure of the storage according to the embodiment will be described below. Shelf brackets 40 are respectively locked in a plurality of locking holes 34 in the inner box 14 and the rack support posts 44, 44 which are located in the same plane and are vertically separated from each other. Then, the shelf nets 46 are placed on the plurality of shelf receivers 40 located on the left side across the center in the width direction, and the shelf nets 46 are placed on the plurality of shelf receivers 40 located on the right side. As shown in FIG. 3 and FIG. 4, a plurality of shelving nets 46 are horizontally separated from each other and are vertically arranged in multiple stages in the refrigerator. And each shelf network 46
By placing the article to be refrigerated on, the article can be refrigerated and stored in a display state.

The load of the plurality of shelving nets 46 and the articles to be refrigerated placed on the shelving nets 46 is transferred via the shelves 40 to the inner box 1.
Join 4 In this case, since the bent portion 36 is formed along the locking hole group in the vicinity of the locking hole group formed in the side plate 20 of the inner box 14, the locking hole group is not formed. The rigidity of the side plate 20 against the applied load is high, and the side plate 20 can be effectively prevented from peeling from the heat insulating material 16. That is, it is possible to prevent deterioration of the heat insulating effect due to the peeling of the inner box 14 from the heat insulating material 16. In addition, since the inner box 14 can be prevented from being deformed, each shelf net 46
Can always be placed stably in a horizontal state.

The side plate 20 of the inner box 14 has the bent portion 3
The second bent side 20b formed by further bending the first bent side 20a bent to form 6 extends to the front opening 18a of the heat insulating box body 18. That is, the thickness dimension (thickness including the outer case 12 and the inner case 14) of the heat insulating box 18 in the front opening 18a is set to be thin, and the opening area of the opening 18a is greatly increased. Thereby, the side frame rod 26 in the door frame 26 in which the transparent door 28 is disposed.
It is possible to widen the distance between a and 26a, and the side frame rod 26
It is possible to prevent the visibility of the article to be refrigerated from decreasing due to the protrusion of a inside the opening 18a. In other words, the two side frame rods 26a, 26a of the door frame 26 are the shelves 4
Since it is located outside the effective width area in the refrigerator in which 6 is arranged (see FIG. 5), the visibility of the left and right refrigerated articles stored in the refrigerator is good.

The cool air sent from the internal fan 70 to the inside of the refrigerator is spread throughout the inside of the refrigerator through the rear cold air passage 48, the front cold air passage 50 and the central cold air passage 52, so that the articles to be refrigerated can be efficiently stored. Can be cooled. Moreover, the inner box 14
Since the side air passage 54 through which the cool air flows is ensured by the first bent side 20a and the second bent side 20b formed on the side plate 20, the cool air is efficiently circulated through the passage 54 as well. Therefore, it is possible to uniformly cool the entire inside of the refrigerator without being influenced by the placed state of the article to be refrigerated.

FIG. 6 shows a modified example of the inner box structure. Although the basic structure is the same as that of the above-mentioned embodiment,
The inner projecting end of the side frame rod 26a of the door frame 26 is set to be located outside the line L that contacts the inner surface of the side plate 20 of the inner box 14. This makes it easier to take in and out the refrigerated item and the shelf net 46, and
The visibility of the article to be refrigerated is also improved.

In the embodiment, the case where the sliding type door is arranged in the heat insulating box has been described. However, even if the opening and closing type door is pivotally supported at one side, the heat insulating box can be opened. It is also the case that the visibility of the articles to be refrigerated stored in the refrigerator is improved by the configuration in which the opening area is made large. Further, the shelf member is not limited to the shelf network as in the embodiment and may be a shelf plate.

[0020]

As described above, according to the inner box structure of the storage according to the present invention, the rigidity is improved by forming the bent portion in the vicinity of the locking hole group formed in the inner box. However, it is possible to effectively prevent the inner box from peeling off from the heat insulating material due to the load applied through the shelf bracket. Therefore, the heat insulating effect of the heat insulating box does not deteriorate, and the refrigerated article can be efficiently refrigerated and stored. Further, since the inner box is prevented from being deformed, the shelf member placed on the shelf receiver can always be stably held in a horizontal state.

By bending the end portion near the opening side of the side plate in the inner box to the outer box side, the opening area of the front opening of the heat insulating box can be greatly increased, and the refrigerated object stored in the refrigerator can be stored. The effect that the visibility of an article can be improved is produced. Also before
Inside of the side frame rod of the door frame mounted inside the opening
Line where the protruding end on the side contacts the inner surface of the side plate of the inner box
By setting it to be located outside,
The shelf members can be taken in and out more easily, and items to be refrigerated
Also has good visibility.
