A large gap S is taken.

The left and right side panels 40 are provided so as to face each other. The side panel 40 is formed of a metal plate, and as shown in FIG. 2, as shown in FIG. 2, the side panel 40 has a width that is equal to the depth of the upper surface of the refrigerator body 10 and a width that is equal to the height of the column 20. And a short bent portion 42 bent at a right angle toward the opposite direction at both longitudinal edges (front and rear edges) of the panel body 41 in the length direction.
As shown in FIGS. 4 and 8, linear flanges 45 and 46 that are bent at right angles toward the back side are formed on both upper and lower edges of the side panel 40. However, the flanges 45A and 46A formed on the upper and lower edges of the panel body 41 have a double plate structure folded on the back side, and the thickness is doubled as shown in FIG. Yes.

In the posture in which the front and rear column bodies 20 are sandwiched between the front and rear bent portions 42, the side panel 40 has L-shaped front and rear end portions in the lower edge flange 46 as shown in FIG. 4. As shown in FIG. 8, the front and rear end portions of the upper edge flange 45 that are L-shaped in the gap S provided below the outer edge portion of the lower surface plate 26 are the upper surface plates of the front and rear column bodies 20. 25 is applied to the first side plates 21 of both column bodies 20 while covering the upper part of the L-shaped outer edge portion. After that, the front and rear end portions of the panel main body 41 in the side panel 40 are screwed and fixed to the first side plate 21 of the front and rear column bodies 20 at two locations on the upper and lower sides, respectively. As a result, the side panels 40 are stretched between the columnar bodies 20 that are paired in the front and rear directions.
Here, in order to absorb manufacturing tolerances and mounting tolerances of the column body 20 and the side panel 40, as shown in FIG. 6, both front and rear end portions of the flange 45 on the upper edge of the side panel 40 and front and rear column bodies are provided. A clearance c of a small size is set between the upper surface plate 25 and the upper surface plate 25.

The front panel 50 is configured to be openable and closable with respect to the left and right pillars 20 on the front side, and the mounting structure will be briefly described.
As shown in FIG. 5, the front panel 50 is configured by integrally assembling synthetic resin corner bodies 52 at both left and right ends of a panel body 51 made of a metal plate. Each corner body 52 is formed with a vertically long mounting plate 53 protruding toward the back side, a hook 55 is provided at the upper end thereof, and an elastic locking portion 56 is provided at a position near the lower end.
In the column 20, as shown in FIG. 3, a latching groove 30 is notched and formed in a corner portion extending from the upper end of the second side plate 22 facing the front to the top plate 25. A first projecting piece 31 is cut and raised toward the back side at the lower edge, and a locking opening 32 is formed at a position near the lower end of the second side plate 22. Is cut and raised toward the back side.

Further, the elastic locking portion 56 is pushed into the locking opening 32 and is prevented from coming off, so that the front panel 50 is held in the closed position. At this time, the upper surface of the front panel 50 (corner body 52) is located slightly lower than the upper edge of the side panel 40.

  When opening the front panel 50, when the lower end portion of the front panel 50 is lifted to the near side from the state of FIG. 6, the elastic locking portion 56 is elastically displaced and pulled out from the locking opening 32 to the near side, and the hook When 55 is swung in the opening direction while being received by the first projecting piece 31 and the front panel 50 is swung to the horizontal position and then pushed into the column 20 side, as shown in FIG. The rear edge of the front panel 50 enters and engages with the insertion groove 57 on the proximal end side of the hook 55 and the protruding edge of the mounting plate 53 is received by the first protruding piece 31. The swinging in the closing direction due to is restricted, that is, held in the open state.

  In this embodiment, as shown in FIGS. 2 and 8, the upper surface of the upper surface plate 25 of the four columnar bodies 20, specifically, the L-shaped upper portion of the upper surface plate 25 at both ends of the side panel 40 is formed. A receiving plate 60 made of a metal plate having a rectangular shape in plan view is attached to a region inside the outer edge portion covered with the flange 45 of the edge by welding or the like. When the receiving plate 60 is affixed, the upper surface of the receiving plate 60 is positioned above the flange 45 on the upper edge of the side panel 40, in other words, on the upper surface plate 25 of the column body 20 The high level surface 61 located above the flange 45 of the edge is formed.

The vertical refrigerator according to the present embodiment has the above-described structure. When the product is stored in a product warehouse after manufacturing, the vertical refrigerator may be stacked in two stages up and down via cardboard D as shown in FIG. is there. In that case, the legs 12 provided at the four corners of the bottom surface of the upper refrigerator R are placed on the four corners of the upper surface of the machine room 15 of the lower refrigerator R with the cardboard D interposed therebetween. As shown, the four legs 12 provided on the bottom surface of the upper refrigerator R are positioned higher than the upper surface plate 25 of the columnar body 20 erected at the four corners of the machine room 15 of the lower refrigerator R across the cardboard D. It is placed on the surface 61 and receives a load. That is, being placed on the flange 45 at the upper edge of the side panel 40 is avoided, and the side panel 40 is prevented from buckling.
When the refrigerator legs are relatively thin, the upper refrigerator R is placed on the upper surface of the machine room 15 of the lower refrigerator R via a cardboard, with the legs removed for the upper refrigerator R. In this case, in this case, the four corners of the bottom surface of the refrigerator main body 10 in the upper refrigerator R are formed on the upper plate 25 of the columnar body 20 erected on the four corners of the machine room 15 of the lower refrigerator R with the cardboard interposed therebetween. It will be put on the high level surface 61, and it is avoided that it is similarly put on the flange 45 of the upper edge of the side panel 40.

  Further, when the product is packed and transported, the upper surface of the machine room 15 is covered with a packing member made of reinforced cardboard and a support member, and between the packing member and the cardboard laid on the bottom surface of the refrigerator main body 10. In some cases, a packing form is used in which a tie band is wrapped around and tightened. In this case, the four corners of the packing member can be placed on the flange 45 on the upper edge of the side panel 40 because the four corners of the packaging member 15 are placed on the high surface 61 of the upper surface plate 25 of the columnar body 20 erected on the four corners. This avoids the load from the packing member accompanying the tightening of the tie band from being applied to the side panel 40, and similarly prevents the side panel 40 from buckling and deforming.

  In addition, when fixing the receiving plate 60 to the upper surface plate 25 of each columnar body 20, a plurality of types of metal plates having different thicknesses are prepared and selectively placed, or the number of stacked thin metal plates is changed. Thus, if the thickness of the receiving plate 60 can be changed, the high-order surfaces 61 of the top plate 25 of each columnar body 20 can be arranged on the same height surface. Therefore, for example, when stacking another refrigerator R on the machine room 15 of one refrigerator R, it can be stably placed without rattling.

The upper surface 61A located above the flange 45 at the upper edge of the side panel 40 is formed.

  As in the first embodiment, it is avoided that a load is applied to the side panel 40 from above, and the side panel 40 is prevented from buckling. In particular, since the high-order surface 61A is integrally formed by knocking out the upper surface plate 25A, an increase in the number of parts can be avoided, and the manufacturing cost can be reduced.

  Further, since the upper surface 61A is integrally provided on the upper surface plate 25A of the column 20A, as shown in FIG. 12, the height of the rear edge 30A of the retaining groove 30 that functions to hold the front panel 50 in the open position. The height position is set to a high position as compared with the height position (symbol h) in the first embodiment. Therefore, the holding posture in the open position of the front panel 50 is a steeply downward posture as compared with the first embodiment, that is, the lower end position of the front panel 50 remains at a low position from the installation surface, and the operator's hand is easy to reach. This is convenient when the front panel 50 is opened and closed.
