As in these patent documents, the left and right side plates of the front case are formed in a straight shape with uniform length in the front and rear direction, and mounting holes are formed in these side plates to allow the protrusion of the rear case to pass through. When the front and rear cases are joined using the protrusion and the mounting hole, the side plate of the front case and the side wall of the rear case largely overlap, increasing the contact area between the two cases. Therefore, it is inevitable that the cold heat inside the refrigerator is conducted to the front case via the rear case, causing the temperature of the front case to drop, and dew condensation is likely to occur on the front plate.

The present invention provides a front case made of metal that forms the outside surface of the refrigerator, a rear case made of synthetic resin that is placed on the inside of the refrigerator with respect to the front case, and a heat insulating layer that is placed between the front case and the rear case. The purpose of the present invention is to prevent dew condensation from forming on the front case by suppressing the conduction of cold heat from the rear case to the front case in a storage column provided with a material.

The present invention is directed to a storage that includes a storage main body 1 made of a heat insulating box body 11 having a front opening 10, and a column 19 extending in the vertical direction so as to partition the front opening 10. The support column 19 includes a vertically long metal front case 24 arranged on the front side, a vertically long synthetic resin rear case 25 arranged on the rear side, and an inner structure of these front and rear cases 24 and 25. A vertically long block-shaped heat insulating body 26 is housed. The front case 24 includes a front plate 30 that constitutes the front surface of the support column 19, and a plurality of engagement pieces 34 that partially extend rearward from both left and right ends of the front plate 30. The rear case 25 includes a rear wall portion 40 forming a rear surface, and a pair of side wall portions 41 extending forward from both left and right ends of the rear wall portion 40. Each engagement piece 34 is provided with a mounting hole 35 , and the inner surface of the side wall 41 is provided with a protrusion 49 corresponding to each mounting hole 35 , and the protrusion 49 is inserted into the mounting hole 35 . By doing so, the front case 24 and the rear case 25 can be joined , and the side wall portions 41, 41 of the rear case 25 have a rear taper whose opposing dimension gradually decreases toward the rear. It is characterized by being formed in a shape .

The front case 24 includes a front plate 30 constituting a front surface, a pair of side plates 31 extending rearward from both left and right ends of the front plate 30, and a portion extending rearward from the rear end edge of each side plate 31. It includes a plurality of engaging pieces 34 formed in an overhanging manner.

Each attachment hole 35 is a rectangular opening having front and rear edges 35a, 35b and upper and lower edges 35c, 35d, and the front edge 35a of the attachment hole 35 is located further forward than the rear edge 31a of the side plate 31. .

On the front plate 30, engagement bodies 36, which are composed of a pair of left and right engagement pieces 34, are installed at multiple locations on the top and bottom, and the engagement bodies 36A located on the upper edge of the front plate 30 and on the topmost stage. The distance defined by the upper edge 35c of the attachment hole 35 formed in the engagement piece 34 that constitutes the front plate 30 is defined as D1, and When the distance defined by the lower edge 35d of the attachment hole 35 formed in the mating piece 34 is defined as D2, the relationship D1<D2 holds true.

The upper end edge of the engaging piece 34 constituting the uppermost engaging body 36A and the upper end edge of the front plate 30 are formed at the same height position.

In the present invention, the storage column 19 is provided with a front case 24, a rear case 25, and a heat insulator 26 housed inside these front and rear cases 24 and 25. The front case 24 includes a front plate 30 constituting a front surface, and a plurality of engagement pieces 34 partially projecting rearward from both left and right ends of the front plate 30. Attachment holes 35 into which protrusions 49 formed on the side wall portion 41 of the rear case 25 are inserted are formed in each of the engaging pieces 34 that are partially projecting from the rear case 25 . As described above, according to the present invention, the overlapping area of both cases 24 and 25 where these engaging pieces 34 and side wall portions 41 overlap can be suppressed, and the conduction of cold heat from the rear case 25 to the front case 24 can be suppressed. Therefore, it is possible to effectively prevent dew condensation from forming on the front case 24. In other words, compared to a configuration in which the side plates are formed to protrude over the entire vertical direction of both left and right ends of the front plate and mounting holes are formed in the side plates as in Patent Document 1, the cases 24 and 25 overlap each other. Since the area can be made smaller in each step, the conduction of cold heat from the rear case 25 to the front case 24 can be suppressed, and dew condensation can be prevented from forming on the front case 24.

When the front case 24 is provided with the side plates 31 , 31 , that is, the front case 24 includes the front plate 30 , the pair of side plates 31 , 31 extending rearward from both left and right ends of the front plate 30 , and the side plates 31 . If it is provided with a plurality of engagement pieces 34 that are formed to partially project backward from the rear end edge, by providing the side plate 31, the entire front case 24 has a U-shaped cross section. Therefore, it is possible to improve the rigidity of the front case 24 and further improve the rigidity of the support column 19.

Each mounting hole 35 is a rectangular opening having front and rear edges 35a, 35b and upper and lower edges 35c, 35d, and the front edge 35a of the mounting hole 35 is located further forward than the rear edge 31a of the side plate 31. Since the mounting hole 35 can be formed across both the side plate 31 and the engaging piece 34, the opening area of the mounting hole 35 can be reduced while suppressing the overhanging area of the engaging piece 34 from the side plate 31. Can be made larger. If the overhanging area of the engaging piece 34 from the side plate 31 can be suppressed in this way, the overlapping area of the front and rear cases 24 and 25 can be reduced, thereby reducing the conduction of cold heat from the rear case 25 to the front case 24. This can prevent dew condensation from forming on the front case 24. Furthermore, if the opening area of the mounting hole 35 can be increased, the engagement area between the mounting hole 35 and the protrusion 49 can be increased, which increases the joint strength of the front and rear cases 24 and 25, and 19 can be improved in rigidity.

When the side wall portions 41, 41 of the rear case 25 are formed in a tapered shape with the opposing dimension gradually decreasing toward the rear, the opposing dimension of the side wall portions 41, 41 becomes narrower in the front-rear direction. Compared to the case where it is formed in a uniform straight shape, it is possible to suppress the blind area inside the refrigerator when viewed from the front side and to expand the visible area inside the refrigerator when viewed from the front side. Moreover, it is possible to obtain a visual effect that makes the inside of the refrigerator appear larger when viewed from the front side.

In the column 19 formed by joining the front and rear cases 24 and 25 as in the present invention, for example, only the front case 24 is fixed to the heat insulating box 11, and the shelf column 28 on which the shelf net 17 is attached to the rear case 25 If the weight of the stored items placed on the shelf network 17 is large and a large load is applied to the rear case 25 via the shelf pillars 28, the attachment holes 35 and the protrusions 49 There is a risk that the engagement state between the front and rear cases 24 and 25 may be disengaged, that is, the front and rear cases 24 and 25 may be disengaged, and the rear case 25 may be separated from the front case 24. Further, the rotational moment acting on the rear case 25 in the direction of separating it from the front case 24 increases as the rear case 25 moves upward. In order to solve the above-mentioned problems, in the present invention, the engaging bodies 36 composed of a pair of left and right engaging pieces 34 are installed at a plurality of upper and lower locations, and are attached to the upper edge of the front plate 30 and the uppermost stage. The distance defined by the upper edge 35c of the mounting hole 35 formed in the engagement piece 34 of the engagement body 36A located at When the distance defined by the lower edge 35d of the attachment hole 35 formed in the engagement piece 34 constituting the combination 36C is defined as D2, the relationship of D1<D2 is established. According to this, since the engaging body 36 is arranged above the support column 19 and the engagement portion between the mounting hole 35 and the protrusion 49 is arranged above the support support 19, for example, the shelf net 17 can accommodate a large amount of weight. Even when an object is placed on the rear case 25, the increase in the rotational moment acting on the rear case 25 can be minimized by the engagement portion on the upper side, so that the rear case 25 can be separated from the front case 24. can be prevented.

If the upper edge of the engagement piece 34 constituting the engagement body 36A located at the uppermost stage and the upper edge of the front plate 30 are formed at the same height position, the engagement point will be located at the uppermost position of the support column 19. , it is possible to further suppress an increase in the rotational moment acting on the rear case 25 and to reliably prevent the rear case 25 from separating from the front case 24 .
