<1-3. Characteristic configuration of cooling storage 1>
In the present embodiment, in order to reduce the number of screws (that is, the number of parts), each of the first horizontal members 32a to 32c has a first sheet metal member 321 and a center pillar 31 as shown in FIG. Has a central sheet metal member 311. Both the first sheet metal member 321 and the central sheet metal member 311 are produced by sheet metal processing.

  Each first sheet metal member 321 is provided on the most front side in the first horizontal members 32a to 32c, and has a main surface S1 having a substantially rectangular shape in a plan view from the front and substantially parallel to the zx plane. The central sheet metal member 311 is provided on the most front side in the center pillar 31 and has a main surface S2 substantially parallel to the zx plane. When the first horizontal members 32 a to 32 c are attached to the center pillar 31, the main surface S <b> 1 and the main surface S <b> 2 are substantially flush (that is, in a state where there is no step).

  Hereinafter, the configuration of the central sheet metal member 311 will be described in more detail. As shown in FIGS. 5A and 5B, the central sheet metal member 311 includes a left side plate 312 </ b> L and a right side plate 312 </ b> R as a sandwiched portion 312. The left side plate 312L and the right side plate 312R, that is, the sandwiched portion 312 are integrated with the main surface S2 by sheet metal processing, and are directed rearward from both left and right ends of the main surface S2 substantially parallel to the yz plane.

  Further, it is preferable that the left side plate 312L and the right side plate 312R have two pairs of protrusions 313 protruding in the right direction of the central sheet metal member 311 at predetermined positions in the vertical direction. The two pairs of protrusions 313 are provided in a number corresponding to the number of the first sheet metal members 321.

  Further, the left side plate 312L and the right side plate 312R are formed with notches 314 at predetermined positions in the vertical direction for alignment with the first sheet metal member 321 and the like.

  Next, a more detailed configuration of the first sheet metal member 321 will be described. Each first sheet metal member 321 has a leaf spring clip portion 322 as shown in FIGS. 6A and 6B. Each leaf spring clip portion 322 is integrated with the main surface S1 by sheet metal processing, and extends from one side of the main surface S1 in the left-right direction (left end in the example of FIGS. 6A and 6B) to the rear. It is formed. Each leaf spring clip portion 322 sandwiches the sandwiched portion 312 (see FIG. 5A and the like) with two sheet metal portions facing each other in the left-right direction, and holds the sandwiched portion 312 in a sandwiched position.

  The pair of through holes into which the protrusions 313 of the central sheet metal member 311 are fitted when the first horizontal members 32 a to 32 c are attached to the center pillar 31 in the sheet metal portion inside the leaf spring clip part 322. 323 is formed. 6A, both through holes 323 are hidden, and in FIG. 6B, one through hole 323 is hidden.

  In the present embodiment, each of the first sheet metal members 321 is further a perforated plate portion 324 from the other side of the main surface S1 in the left-right direction (the right end in FIGS. 6A and 6B) toward the rear, Perforated plate portion 324 having through holes formed therein. In the present embodiment, the perforated plate portion 324 is used when the other end side of the first sheet metal member 321 is screwed to the peripheral portions of the openings A1 and A2 in the interior body 22.

  Each first sheet metal member 321 further includes an upper side plate 325 and a lower side plate 326 that are substantially parallel to the xy plane from both ends of the main surface S1 in the vertical direction toward the rear. The front end portions of the upper side plate 325 and the lower side plate 326 are folded back to be stopped by an upper concave portion 3212 and a lower concave portion 3213, which will be described later, to become an upper locking portion 327 and a lower locking portion 328.

  When attaching the first sheet metal member 321 to the central sheet metal member 311, as shown in FIG. 7A, the operator determines the attachment position of one first sheet metal member 321 based on one notch 314, The sandwiched portion 312 is sandwiched between two sheet metal portions facing each other in the left-right direction in the spring clip portion 322. In this state, the operator pulls the first sheet metal member 321 forward and inserts the sandwiched portion 312 between the leaf spring clip portions 322. In the process, two pairs of protrusions 313 formed in the central sheet metal member 311 are fitted into two pairs of through holes 323 formed in the leaf spring clip portion 322. As a result, as shown in FIG. 7B, one end side of the first sheet metal member 321 is fixed to the central sheet metal member 311.

  In the present embodiment, the perforated plate portion 324 provided on the other end side is an opening in the interior body 22 so that the first sheet metal member 321 is horizontally mounted between the interior body 22 and the center pillar 31. It is screwed to the peripheral part of part A1, A2.

  The operator repeats the above steps to attach all the first sheet metal members 321 to the central sheet metal member 311.

<1-4. Other configurations of first horizontal member 32 and second horizontal member 33>
Reference is now made to FIG. 2 again. The second horizontal member 33 has a second sheet metal member 331. The second sheet metal member 331 is different from the first sheet metal member 321 in that it includes a perforated plate portion similar to the perforated plate portion 324 described above instead of the leaf spring clip portion 322. That is, the 2nd sheet metal member 331 is provided with the perforated board part which goes to back from each of the both ends in the horizontal direction of its principal surface. Other than this, there is no difference between the sheet metal members 321 and 331. Such a second sheet metal member 331 is provided at each end of the opening A2 so as to be laid across between the left peripheral edge (inside the interior body 22) and the right peripheral edge (center pillar 31 side). The perforated plate portion is screwed to the peripheral edge portion of the opening A2.

Reference is now made to FIGS. 8A and 8B.
First, a perspective view of the first breaker 329 before being attached to the first sheet metal member 321 is shown in the upper part of FIG. 8A, and the first part along the line II ′ shown in the upper part of the same figure is shown in the lower part. A cross-sectional view when the sheet metal member 321 and the first breaker 329 are cut is shown.
8B shows a perspective view of the first breaker 329 after being attached to the first sheet metal member 321, and the lower part shows the first along the line II-II ′ shown in the upper part of the figure. A cross-sectional view when the sheet metal member 321 and the first breaker 329 are cut is shown.

  Each of the first horizontal members 32a to 32c described above further includes a first breaker 329 as shown in FIGS. 8A and 8B. The first breaker 329 is made of resin or the like, and a cross section cut in parallel to the yz plane has a substantially “U” shape. More specifically, when the first breaker 329 is attached to the first sheet metal member 321, the first breaker 329 has a main surface S3 that faces the main surface S1 of the first sheet metal member 321 in the front-rear direction. The first breaker 329 further includes an upper side plate 3210 and a lower side plate 3211 that are substantially parallel to the xy plane from the both ends in the vertical direction of the main surface S3 toward the front when attached to the first sheet metal member 321. The tip portions of the upper side plate 3210 and the lower side plate 3211 are an upper concave portion 3212 and a lower concave portion 3213 into which the upper locking portion 327 and the lower locking portion 328 are fitted.

  Reference is now made to FIG. 2 again. The second horizontal member 33 further includes a second breaker 332. The second breaker 332 is substantially the same as the first breaker 329. Such a second breaker 332 is attached to the second sheet metal member 331 in the same manner as the first breaker 329.

  As is clear from the above, both the horizontal members 32 and 33 are hollow. Heaters (not shown) for heating the sheet metal members 321 and 331 are provided inside the horizontal members 32 and 33 in order to prevent condensation and the like. In addition, a heat insulating material (not shown) is provided on the rear side of the heater to thermally isolate the inside of the accommodation space.

  As described above, each first horizontal member 32 is attached to the center pillar 31 by the leaf spring clip portion 322 and the sandwiched portion 312. Therefore, when a backward force is applied by putting in and out each drawer, the position of each first horizontal member 32 may be shifted backward. Therefore, in the present embodiment, as shown in FIGS. 2 and 3, a restricting portion 315 </ b> R protruding rightward from the position corresponding to the rear end of the first horizontal member 32 is provided on the right side surface of the center pillar 31. It is formed. Although not shown for convenience, a similar restricting portion is also formed on the left side surface of the center pillar 31.

<1-5. Action / Effect of Cooling Storage 1>
As described above, in the cooling storage 1, the middle partition 3 includes the three first horizontal members 32 (32 a to 32 c). The first horizontal members 32a to 32c are bridged in the left-right direction (that is, the horizontal direction) between the interior body 22 and the center pillar 31 in any one of the openings A1 and A2. Here, the first horizontal members 32 a to 32 c are attached to the center pillar 31 using the leaf spring clip portion 322 and the sandwiched portion 312 without using screws. Moreover, the plate spring clip portion 322 is integrally formed with the first sheet metal member 321 by sheet metal processing, and the sandwiched portion 312 is formed integrally with the central sheet metal member 311 by sheet metal processing. Due to the above two points, when the partition 3 is divided into a plurality of small openings B, the total number of screws can be reduced, so that the number of parts of the cooling storage 1 can be reduced.

  In the present embodiment, the restricting portion 315 (only the restricting portion 315R on the right side is shown) is formed on the left and right side surfaces of the center pillar 31 at a position corresponding to the rear end of the first horizontal member 32. By this restricting portion 315, the backward movement (that is, misalignment) of the first horizontal member 32 including the first sheet metal member 321 can be suppressed.

  Moreover, in this embodiment, as shown in FIG. 2, the heat insulation housing | casing 2 is provided with the detachable cover 23 in order to access the inside of the machine room 5 from an accommodation space. The operator can visually confirm the frost formation on the evaporator blower and the evaporator constituting the cooling unit by opening the lid 23. Accordingly, the second horizontal member 33 on the machine room 5 side is removed more frequently than the first horizontal member 32 that is separated from the machine room 5. Since the left and right sides of the second horizontal member 33 are screwed to the peripheral edge of the opening A2, even if the removal frequency is high, rattling is unlikely to occur. On the other hand, the first horizontal member 32 is fixed to the center pillar 31 by using the leaf spring clip portion 322 and the sandwiched portion 312. Therefore, when the removal frequency increases (that is, when the insertion / removal increases), It tends to cause sticking. Therefore, it is not preferable to use the first horizontal member 32 for the entire side close to the machine room 5.

<1-6. Addendum>
In the above embodiment, the first horizontal member 32 is provided with the leaf spring clip portion 322, and the center pillar 31 is provided with the sandwiched portion 312. However, the present invention is not limited thereto, and a leaf spring clip portion equivalent to the leaf spring clip portion 322 may be provided on the center pillar 31, and a sandwiched portion equivalent to the sandwiched portion 312 may be provided on the first horizontal member 32. Absent.

  Moreover, in the said embodiment, the partition 3 was demonstrated as the center pillar 31 provided. However, the present invention is not limited to this, and the partition 3 may be configured by a combination of the first horizontal member 32 and the second horizontal member 33 or may be configured by only the first horizontal member 32. In this case, the first horizontal member 32 or the second horizontal member 33 is bridged from the left side to the right side of the accommodation space.

  Moreover, in the said embodiment, the cooling storage 1 was demonstrated as a drawer type. However, the present invention is not limited thereto, and in the cooling storage 1, the heat insulating door 4 may be attached to the heat insulating housing 2 by, for example, a plurality of hinges and rotatable about the axes of the plurality of hinges.

  The cooling storage of this indication can reduce a number of parts, and is suitable for a commercial refrigerator.
