Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to an improvement in the support structure of the bottom plate, called a so-called deck pan, of an inner box that forms a product display chamber inside in a multi-stage refrigerated open show case.

[Conventional technology]

A multi-stage refrigerated open-shelf case shown in FIG. 5 is known. In Figure 5,
The main case 2 of the refrigerated open case 1 is
A cold air circulation path 5 is provided between the outer box 3 having an insulating wall and the inner box 4, which has an opening 2a on the front for entering and exiting the product.
It is composed by forming. A fan 6 and a cooler 7 are disposed in the cold air circulation path 5, and both ends of the cold air circulation path 5 are open to the opening 2a, with a cold air outlet 5a at the upper open end and a cold air outlet 5a at the lower open end. A cooling suction port 5b is formed. The inside of the inner box 4 forms a product display room 8, and is provided with shelves 9 that partition the room into a plurality of upper and lower stages. The bottom wall of the inner box 4 is formed with a removable bottom plate 41 called a so-called deck pan so that the cold air circulation path 5 and the fan 6 can be cleaned and inspected. That is, the bottom plate 41
As shown in FIG. 6, the back plate 42 forming the back wall of the inner box 4 and the opening 2 forming the front wall of the inner box 4
Front and rear edges are supported by lower edges 42a and 43a of the front plate 43 on the lower side that are bent in opposite directions to each other, making it removable. Further, as shown in FIGS. 6 and 7, the back plate 42 and the front plate 43
are provided with a large number of locking holes 11 that are arranged vertically and form pairs on the left and right, and are held above the bottom plate 41 by engaging a pair of left and right protrusions 12a at both front and rear ends with the locking holes 11, A wire rack 12 is provided on the top surface on which the product is placed.

In the refrigerated open-air case 1 described above, indoor air is turned into cold air by the cooler 7 by the fan 6, and is circulated in the direction of the arrow A within the cold air circulation path 5. Thus, the cooling is blown out from the cold air outlet 5a toward the cold air intake 5b, forming a cold air curtain 13 at the opening 2a that thermally isolates the inside of the product display room 8 from the outside air, and a portion of the cooling air also flows into the room. to keep products indoors cool. In the product display room 8, there are shelves 9 to enhance the product display effect.
The shelf board 92 is supported with its rear end inclined at an appropriate angle by a shelf support 91 which is cantilever-supported by the inner box 4, and the wire rack 12 has a protrusion 12a at an appropriate height and inclined at an appropriate angle. They are held by engaging with appropriate locking holes 12, and products are displayed on these shelf boards 92 and wire racks 12.

[The problem that the idea aims to solve]

By the way, in the conventional refrigerated open show case, the production cost is high because it is equipped with a wire rack 12 at the bottom of the product display room 8 for effectively displaying products, and the inside of the cold air circulation path 5 and the fan 6 have to be cleaned during maintenance. In order to inspect it, both the bottom plate 41 and the wire rack 12 must be removed, which has the disadvantage of complicating maintenance.

Therefore, this idea was developed by configuring the bottom plate that forms the inner box to also have a product display function, and by eliminating the wire rack that was previously required, the refrigerated storage can reduce manufacturing costs and facilitate maintenance. The purpose is to provide an open case.

[Means to solve the problem]

To achieve the above objective, this design has an opening on the front, a product display room on the inside and a cold air circulation path between the outside and the outer box, and the bottom is removable. In the refrigerated open show case, which includes an inner box and forms a cold air curtain by blowing from the cold air outlet of the cold air circulation path toward the inlet at the front opening, the back wall of the inner box and the front under the opening are provided. Each wall is provided with locking holes lined up vertically, and a plurality of rows of locking holes are provided on the left and right. A bottom plate support having a locking part that is removably locked in the locking hole is provided on each of the front and back wall sides, and the front and back wall sides are selectively locked in the vertically arranged locking holes. The front and rear edges are removably engaged with the bottom plate supports to support the bottom plate.

[Effect]

According to the refrigerated open case of this invention based on the above means, a plurality of locking holes 4 are provided in the back wall (back plate 42) and the front wall (front plate 43) of the inner box 4.
Locking holes 45, 4 at appropriate height positions among 5, 46
6 is selected to attach the bottom plate supports 17 and 18, and the bottom plate 41 can be supported on these bottom plate supports 17 and 18. By selecting the locking holes 45 and 46, the bottom plate 41 can be adjusted to an appropriate support height or slope. It becomes possible to effectively display products on the bottom plate 41 by installing it at an angle. Therefore, it is possible to eliminate the wire rack 12 that was conventionally required to effectively display products at the bottom of the product display room 8, thereby reducing manufacturing costs and making it easier to clean the inside of the cold air circulation path 5. When inspecting, maintenance work can be easily performed by simply removing the bottom plate 41. Moreover, since the bottom plate supports 17 and 18 are provided with a length that can support substantially the entire width of the bottom plate 41, the bottom plate supports 17 and 18
8, the bottom plate always sufficiently partitions between the inside of the warehouse (product display room 8) and the cold air circulation path 5, and does not impair the original function of the bottom plate, which is to form the cold air circulation path 5.
