Abstract

PURPOSE:To prevent a shield member from being all wet by a method wherein a shield member of a paper material to shield the side of each of a heat insulating wall and a cold air passage is disposed on the surface on the heat insulating space side of the clear sheet, on the inner side of a refrigerator, of a multilayer clear plate. CONSTITUTION:A shield member 46 made of a paper material to shield the side of each of a heat insulating wall 2 and a cold air passage is laminated on the surface on the heat insulating space 25 side of a clear sheet 23, on the inner side of a refrigerator, of a multilayer clear plate 21 of which a heat- insulating side plate 20 consists mainly. The clear sheet 23 on the inner side of a refrigerator is served as a partition piece by which the shield member 46 is partitioned away from the heat insulating wall 2. Since the paper material has moisture absorption property, the paper material performs an action to gradually absorb moisture of air in the heat insulating space 25 of the multilayer clear plate 21. As a result, the shield member 46 is prevented from being all wet.

Description

[Detailed Description of the Invention] [Object of the Invention] Industrial Field of Application The present invention relates to a showcase equipped with heat insulating side plates mainly made of transparent plates disposed on both left and right sides of a heat insulating wall and allowing a storage room to be seen through. .

Conventional Technology In a so-called oven-type showcase that has an opening for loading and unloading products in the front, a flow of cold air (i.e., a cold airflow) is formed in the opening to cool the inside of the cabinet. There is Japanese Utility Model Application Publication No. 63-91065. In this publication, a plate member and a glass side plate are provided, which wrap the side surface of a duct part to form a cold air flow on the side of the showcase body, and the plate member connects the showcase body and the glass side plate. A technique is disclosed in which the device is inserted between the two and fixed by being tightened with a fixing screw.

Problems to be Solved by the Invention In the above-mentioned conventional technology, since the plate member is separate from the glass side plate, when the plate member is sandwiched between the showcase body and the glass side plate, the plate member It is difficult to perform this work, and it is also necessary to form holes for the fixing screws to pass through, making the manufacturing and installation work extremely troublesome. In addition, the thickness of the side wall becomes thicker and heavier due to the sandwiching of the plate members, and this is especially noticeable when the plate members are made of steel. There was a fear that it would become too large.

Therefore, in the present invention, without changing the thickness of the heat insulating side plate,
The present invention provides a low-temperature showcase in which the side surfaces of a heat-insulating wall are shielded.

[Structure of the invention]

Means for Solving the Problems The low-temperature showcase provided by the present invention has a storage chamber formed of an insulating wall having an entrance for articles in the front, a cold air passage surrounding the storage chamber, and a left and right side wall of the insulating wall. A pair of left and right heat insulating side plates, which are mainly composed of multi-layer transparent plates that are arranged in It is provided with a shielding member that is formed by pasting a paper material to a portion facing each side and shields each side.

Function: A paper shielding member that shields each side of the heat insulating wall and the cold air passage is attached to the side of the transparent plate on the inside of the refrigerator, which constitutes the main body of the heat insulation side plate, on the side of the heat insulation space. The transparent plate acts as a spacer separating the shielding member and the heat insulating wall. Furthermore, since the paper material has a hygroscopic effect, the paper material gradually absorbs the moisture in the air within the heat insulating space in the multilayer transparent plate.

Reference numeral 45 denotes an expandable sealing member provided on the outer surfaces of the two closed main plates 32 and 33, which is compressively deformed by attaching the heat insulating side plate 20 to the heat insulating wall 2, and seals between the heat insulating wall 2 and the heat insulating side plate 20. Maintain the airtightness of the joints. The sealing member 45 is preferably a band-shaped foamed resin having countless closed cells, with adhesives 45A and 45B applied to both the inner and outer surfaces as shown in FIG. It is preferable to attach it to 32.33.

Reference numeral 46 is formed in a band shape on the outer surface of the transparent plate 23 on the inner side of the multi-layer transparent plate 21, that is, the surface on the side of the heat insulating space 25, and is formed in a band shape on the side surface of the heat insulating wall 2 and the partition plate 4, the cold air passage 7, specifically the first This is a shielding member that shields the closing plate 32 and the sealing member 45 from being seen from the outside, and is formed by, for example, applying a paper material with adhesive on one side in an inverted shape as shown in FIG.

The width (L) of this shielding member 46 is the width (M) from the outer circumferential edge of the side surface of the insulation wall 2 to the inner circumferential edge of the side surface of the partition plate 4, as shown in FIG.
In other words, the inner circumferential edge of the shielding member 46 is slightly larger than the inner circumferential edge of the partition plate 4, and when viewed diagonally rearward from the side of the low temperature showcase 1 as shown by the arrow in FIG. Also, the inner circumferential ends of each side surface of the partition plate 4, the first closing plate 32, and the seal member 45 are shielded by the shielding member 46.

Note that a paper material is used as the shielding member 46, and since this paper material has some hygroscopicity, it can absorb moisture in the heat insulating space 25 in the multi-layer transparent plate 21. The amount of desiccant installed can be reduced.

According to this configuration, a paper shielding member 46 that shields the side surface of the heat insulating wall 2 is formed on the surface of the transparent plate 23 on the inner side of the storage compartment of the multilayer transparent plate 21 constituting the heat insulating side plate 20 on the heat insulating space 25 side. Therefore, since the transparent plate 23 on the inner side of the refrigerator functions as a spacer separating the shielding member 46 and the heat insulating wall 2, specifically, the sealing member 45, the adhesive 45B of the sealing member 45 adheres to the shielding member 46 and causes the shielding. It is possible to prevent the member 46 from becoming wet with water. Moreover, the shielding member 46 is in a sealed state in the heat insulating space 2.
Because it is formed on the 5-side surface, it will not be damaged by external mischief or deteriorated by changes in outside air humidity.

Furthermore, since the shielding member 46 is made of paper material, the amount by which the multilayer transparent plate 21 becomes thicker is negligible, and its weight hardly increases. Further, since it is made of paper material, it has the advantage of being very inexpensive and easy to work with, and since paper material has a moisture absorbing effect, the amount of desiccant in the spacer 26 can be reduced.

〔Effect of the invention〕

As detailed above, according to the present invention, the paper material that shields each side of the heat insulating wall and the cold air passage is attached to the surface on the heat insulating space side of the transparent plate on the inner side of the multi-layer transparent plate constituting the main body of the heat insulating side wall. By disposing the shielding member, the transparent plate inside the refrigerator acts as a spacer that separates the shielding member from the heat insulating wall, and it is possible to prevent the shielding member from getting wet. Furthermore, since the shielding member is located on the side of the heat insulating space of the multilayer transparent plate, the thickness of the multilayer transparent plate is not increased, and since it is made of paper material, its weight is hardly increased. Moreover, the shielding member may be damaged by external mischief, etc.
It will not deteriorate due to changes in outside air humidity.
