Next, the structure of the storage body 1 will be described with reference to FIGS. 1 to 5. As described above, the storage body 1 is
Insulation wall 11 covering the periphery of the machine room 5 and insulation box 2
The heat insulating wall 11 of the machine room 5 and the heat insulating box 2 are integrally formed. And this storage body 1
Includes an inner box 31 forming the inner surface of the storage chamber 3, an outer box 32 forming the outer shell of the storage body 1, and a machine room box 33 forming the inner surface of the machine room 5. A heat insulating material 34 such as urethane is injected and foamed into the space between the inner box 31, the outer box 32 and the machine room box 33 made of a metal plate.

The back plate 37 of the outer box 32 continuously covers the back surface of the heat insulating box body 2 and the back surface of the heat insulating wall 11 of the machine room 5, and the back surface of the heat insulating box body 2 and the heat insulation of the machine room 5 are insulated. Wall 1
There is no joint between the back plate and the back surface of No. 1. Similarly, the side plate 38 of the outer box 32 continuously covers the side surface of the heat insulating box body 2 and the side surface of the heat insulating wall 11 of the machine room 5.
In addition, an inner reinforcing member 41 and an outer reinforcing member 42 are vertically long in the corners on both sides of the back surface of the storage body 1. The inner reinforcing member 41 and the outer reinforcing member 42 each have a substantially L-shaped cross section, and have rear surface portions 41a and 42a along the rear surface of the storage body 1,
Side portions 41b, 42b along the side surface of the storage body 1
It consists of Rivet or screw holes 45 are formed in the back surface portions 41a and 42a and the side surface portions 41b and 42b at substantially equal intervals in the vertical direction.

The back plate 37 and the side plate 38 are sandwiched between the inner reinforcing member 41 and the outer reinforcing member 42.
The back plate 37 and the side plate 38 have an inner reinforcing member 4
A fixing hole 46 is formed at a position corresponding to the first hole 45 and the outer reinforcing member 42.

As shown in FIGS. 4 and 5, the tip of the back plate 37 reaches the central portion of the back surface 41a of the inner reinforcing member 41, and the rear surface of the back surface 41a of the inner reinforcing member 41. Spot welding is performed at the welding point 51. The welding location 51 is located approximately in the middle of the space between the holes 45 of the inner reinforcing member 41. On the other hand, the side plate 38
Of the inner reinforcing member 41 overlaps the side surface portion 41b of the inner reinforcing member 41, is bent near the corners of the inner reinforcing member 41, and reaches the central portion of the rear surface portion 41a of the inner reinforcing member 41. Is facing. Outside reinforcing members 42 are arranged outside the front end portions of the side plate 38 and the back plate 37, and the inside reinforcing members 41 and the outside reinforcing members 42 are provided.
The side plate 38 and the back plate 37 are sandwiched between and.
Then, the rivet 53 is provided on the back surface 4 of the inner reinforcing member 41.
The inner reinforcing member 41, the rear plate 37, and the outer reinforcing member 42 are connected to each other by fitting in the holes 45 of 1a, the hole 46 of the rear plate 37, and the hole 45 of the rear portion 42a of the outer reinforcing member 42. Similarly, the inner reinforcing member 41, the side plate 38, and the outer reinforcing member 42 are also joined by the rivets 53.

The front end of the side plate 38 is bent to cover the front surface of the heat insulating box 2, and the reinforcing member 54 is attached to the corner of the side plate 38 formed by this bending. There is.

As described above, the periphery of the machine room 5 arranged at the upper part of the storage main body 1 is covered with the heat insulating wall 11. Since the heat insulating wall 11 has a rigidity higher than that of the panel, the object is Even if it collides, it rarely bends or deforms easily. Further, it is not necessary to provide a mounting member in the machine room 5 for mounting the panel. Moreover, since the drainage pipe 16 is arranged, the water that has entered the machine room 5 can be quickly drained.

The back plate 37 of the heat insulation wall 11 of the machine room 5
Since the back plate 37 of the heat insulating box 2 is composed of one continuous plate, there is no joint at the boundary between the heat insulating wall 11 and the heat insulating box 2. Therefore, it is possible to prevent the back plate from flipping up when an object hits the joint.

Since the inner reinforcing member 41 and the outer reinforcing member 42 are used to connect the rear plate 37 and the side plate 38, the work of attaching the inner reinforcing member 41 and the outer reinforcing member 42 and the rear plate 37 The connection with the side plate 38 is performed at the same time. Therefore, unlike the conventional example shown in FIG. 6, there is no need to connect the back plate 02 and the side plate 03 with the screw 04. As a result, the man-hours for assembling the outer box are reduced, and the assembling work is simplified.

Further, in the embodiment, the back plate 3
The width of 7 is smaller than the lateral width of the storage body 1, and is insufficient to cover the entire back surface of the storage body 1. However, the end portion of the back plate 37 has the back portion 41 of the inner reinforcing member 41.
It is sandwiched between a and the rear part 42a of the outer reinforcing member 42, and is attached. The shortage of the width of the rear plate 37 is complemented by the rear parts 41a and 42a of the two reinforcing members 41 and 42.

In this way, since there are no joints between the plates on the back surface of the heat insulating box 2, it is possible to prevent the joints from being turned up even if an object collides.

As in the side plate 38 shown in FIG. 4, when the end portions are bent and attached to both the reinforcing members 41 and 42, when a tensile force is applied to the side plate 38, The bent portion at the end of the side surface plate 38 can support this pulling force, and the mounting portion of the rivet 53 is not subjected to excessive force, so that the hole 46 of the side surface plate 38 is deformed or damaged. There are few things. However, if the ends of the plates attached to both the reinforcing members 41 and 42 are not bent and attached, a pulling force is largely applied to the attachment portion of the rivet 53, and the attachment holes of the plates may be deformed or damaged. is there. And, as mentioned above,
The back plate 37 does not have its ends bent, and the reinforcing members 41,
It is attached to 42 and cannot support the pulling force at the bent portion. Therefore, the end portion of the back plate 37 is spot-welded to the inner reinforcing member 41 at the welding point 51, and the pulling force is supported at this welding point 51 to prevent a large pulling force from being applied to the mounting portion of the rivet 53. .

Further, in this embodiment, the back plate 37 is spot-welded to the inner reinforcing member 41,
The outer reinforcing member 42 is not spot welded. Therefore, even when a portion of the outer reinforcing member 42, which is a corner portion of the storage main body 1, collides with an object and is damaged, the outer reinforcing member 4
Since 2 is not spot-welded to the back plate 37, it can be easily separated from the back plate 37, and the outer reinforcing member 42 can be easily replaced. However, when the outer reinforcing member 42 is spot-welded to the back plate 37, it is difficult to separate the outer reinforcing member 42 and the back plate 37,
The back plate 37 also needs to be replaced together.

The embodiment of the present invention has been described above in detail.
The present invention is not limited to the above embodiment,
Within the gist of the present invention described in the claims,
Various changes can be made. Modification examples of the present invention are exemplified below. (1) The drainage pipe 16 can be attached by cutting a hole in the heat insulation wall 11 after the heat insulation wall 11 is manufactured, or can be attached in advance before injecting the heat insulating material 34. It is also possible.

(2) In the embodiment, the back plate 37
Is spot-welded to the inner reinforcing member 41, but may be spot-welded to the outer reinforcing member 42. However, spot welding to the inner reinforcing member 41 makes it easier to replace the outer reinforcing member 42. (3) In the embodiment, the storage is a portable freezer / refrigerator, but it may be a storage. Further, it is possible to use a stationary type instead of a portable type.

(4) In the embodiment, the inner reinforcing member 41 and the outer reinforcing member 42 are fixed with rivets, but they can be fixed with screws. (5) In the embodiment, the welding location 51 of spot welding is performed substantially in the middle of the space between the fixing locations by the rivets 53, but the welding location 51 can be changed as appropriate. However, it is more optimal in terms of strength to perform in the middle. It is also possible to perform spot welding at a plurality of locations at intervals between the fixed locations by the rivets 53.

(6) In the embodiment, the rivets 5 on the back surface portions 41a and 42a of the reinforcing members 41 and 42 are used.
3 and the rivets 5 on the side surface portions 41b and 42b
Although the interval of 3 is the same, it is also possible to make the interval of the rivet on the back surface part different from the interval of the rivet on the side surface part.

[0029]

According to the present invention, all four side surfaces of the machine room arranged above the heat insulating box are covered with heat insulating walls, and the heat insulating wall has a heat insulating material arranged therein. Since it is more rigid than the panel, it is less likely to be bent or deformed even when an object collides. Moreover, since this heat insulating wall is formed integrally with the lower heat insulating box body, it is possible to prevent the strength of the boundary between the heat insulating box body and the heat insulating wall from being lowered. Further, since the drainage pipe is arranged so as to penetrate through the lower portion of the heat insulation wall, the machine room can be drained well despite the fact that the heat insulation wall is formed integrally with the heat insulation box.

Further, since the tip of the back plate reaches and is fixed to the back part of the inner reinforcing member and the back part of the outer reinforcing member, even if the width of the back plate is narrower than the width of the heat insulating box,
The shortage can be supplemented by the back surface of the inner reinforcing member and the back surface of the outer reinforcing member. Moreover, even if the back plate and the inner reinforcing member and the outer reinforcing member are small in overlapping portions, since they are reinforced by spot welding, it is possible to prevent a large force from being applied to the mounting portion of the rivet or the screw.

When spot welding is carried out in the approximate middle of the intervals between the fixing points by rivets or screws, the intervals between the fixing points by rivets or screws and the fixing points by spot welding are substantially equal. ,
The fixing strength is less likely to be non-uniform. as a result,
The small strength part is reduced and the strength is improved.
