DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an open showcase in which a bottom plate and a support member are arranged below a storage room.

[0002]

2. Description of the Related Art A description will be given below with reference to FIGS. Reference numeral 1 denotes an open type showcase in which a main body is defined by a heat insulating wall 3 having an opening 2 formed on the front surface.
A cold air passage 7 and an exhibition room 8 are formed by arranging a partition plate 5 including a back plate portion 5B and a top plate portion 5C, and a plurality of bottom plates 6 that are part of the partition plate. One end of the cool air passage 7 communicates with an outlet 9 at the upper end of the opening 2 and the other end communicates with a suction port 10 at the lower end of the opening 2, and a cooler 11 and a blower 12 are installed inside. Further, in the exhibition room 8, a plurality of product mounting shelves 13 each having a fluorescent lamp 16 are provided at the front lower surface, and the front plate 5A and the back plate 5B of the partition plate 5 on which the bottom plate 6 is mounted. A plurality of holes 15 formed at the upper end of the lower end are provided with protrusions 15 at the front and rear ends.
A metal wire rack 15 engaging B and 15C is attached. The wire rack 15 is provided with wires 15A having a fine pitch in the vertical direction in order to prevent the product from falling and falling.

[0003] In the above showcase, the cool air exchanged by the cooler 11 is cooled by the cooler 11, the outlet 9, the exhibition room 8 and the opening 2, the inlet 10, as shown by arrows in FIG. 2.
Circulates in the order of blower 12 and cooler 11. Here, the cool air blown out from the outlet 9 turns into the air inlet 10 after forming an air curtain, and a part of the cool air circulates to the product display room 8 partitioned vertically by the shelf 13. 2 and 3
As shown in the figure, a part of the cool air is also discharged from a plurality of discharge ports 5D formed in the lower part of the back plate of the partition plate 5, thereby cooling the lowermost exhibition area 8A.

[0004]

According to the above prior art, since the wire rack 15 is arranged at intervals on the bottom plate 6, fruits and vegetables are piled up on the wire rack 15. In addition, when the product is placed in the state described above, there is a problem that the load of the upper product is applied to the lowermost product, the lowermost product bites into the wire 15A, and the product is seriously damaged. Bottom plate 6 and wire rack 15
There is also a problem that the effective internal volume of the lowermost exhibition area 8A is reduced because a gap is formed between the blower 1 and the blower 1 that is used daily.
When inspecting 2 and cleaning the heat insulating wall 3 bottom wall, the bottom plate 6,
There is also a problem that it takes time to remove both the wire racks 15. There has also been a problem that the mounting structure of the bottom plate and the wire rack is complicated.

[0005] An object of the present invention is to solve the above problems.

[0006]

According to the present invention, as a means for solving the above-mentioned problems, a partition plate and a bottom plate are arranged in a refrigerator which is defined by a heat insulating wall having an opening formed on one side, and cooling is performed. In an open showcase comprising a cold air passage in which a fan and a blower are installed, and a storage room, a bottom plate suction port is formed in the bottom plate, a blower is provided below the bottom plate, and the partition located in a front part of the storage room. A plurality of holes were respectively provided in the front plate portion of the plate and the back plate portion of the partition plate located at the back of the storage room, and a support member for supporting the bottom plate was provided in each of the holes.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. In FIGS. 4 and 5, the same reference numerals as those in FIGS. 1 to 3 denote the same elements. 4 and 5 show a supporting member (in this embodiment, a wire rack which is the same as the conventional technology is used, and is hereinafter referred to as a wire rack).
5 show open-type showcases 1 and 1 each having a plurality of bottom plate suction ports 6A formed only at the rear portion of each bottom plate 6 mounted on the bottom plate 5. A partition plate 5 and a fan case 5E which is a part of this partition plate are shown. And a high-pressure chamber 22 for accommodating the cooler 11 and the blower 12 is formed in the cool air passage 7 surrounded by the heat insulating wall 3, and at least the blower 12 is provided below the bottom plate 6 and is displayed in the lower part. The cold air in chamber 8A is indicated by arrows 26 and 29
Is drawn into the cold air passage 7 through the bottom plate suction port 6A and the wire rack 15 as shown by the arrow, and a part of the forced circulation flow is reduced from the opening side as shown by the arrow 26 by the static pressure drop in the exhibition area 8A. It is drawn inside 8A, directed to the bottom plate suction port 6A and sucked into the cool air passage 7 to promote cooling of the exhibition area 8A.

The wire rack 15 is supported by the partition plate 5 by engaging projections 15B and 15C at both front and rear ends with holes 14 formed in the front plate portion 5A and the back plate portion 5B of the partition plate 5, respectively. On the other hand, a bottom plate 6 which is a part of the partition plate 5 is placed on the wire rack 15. Accordingly, since the wire rack 15 acts as a support member for the bottom plate 6, it is not necessary to dispose a fine pitch wire 15A for placing products on the wire rack 15, unlike a conventional showcase, and a wire with a coarse pitch is not necessary. 15A is sufficient.

According to the above configuration, since the bottom plate 6 is placed on the wire rack 15, the bottom plate 6 and the wire rack 1
No useless space is formed between the bottom plate 6 and the bottom plate 6, and the contact area between the bottom plate 6 and the commodities is large, so that the effective internal volume of the lowermost display area 8A is not impaired unlike the conventional showcase. Even if the products are placed in the state, the lowermost product does not bite into the wire rack 15, and the bottom plate 6 is removed at the time of checking the cleaning of the blower 12 and the bottom wall of the heat insulating wall 3. The state of the bottom area of the cold air passage 7 can be seen via 15.

[0010]

According to the present invention described above, in an open showcase in which a door or the like is not provided on the front surface and dust or the like easily enters, a blower or a heat insulating wall disposed in a bottom area of a cool air passage is provided. By removing the bottom plate from the support member when inspecting the cleaning on the wall, it is possible to see whether the bottom area of the cool air passage is dirty or not, and it is very easy to inspect the lower part of the bottom of the cold air passage. In addition, since the cool air in the lower part of the storage room is sucked into the cool air passage through the bottom plate suction port formed in the bottom plate, the cooling of the lower part of the storage room can be promoted.
